Specification

Description:FIELD OF THE INVENTION

[0001] The present invention relates to a self-contained bathing device that is capable of offering an enclosed, automated bathing experience with enhanced hygiene, comfort, and personalized environmental control for individual users.

BACKGROUND OF THE INVENTION

[0002] In recent years, there has been an increasing demand for advanced bathing solutions that not only ensure personal hygiene but also offer enhanced comfort, convenience, and privacy. Users seek devices that minimize manual intervention while providing features such as temperature control, efficient water usage, and adaptability to individual needs. The growing trend of compact, multi-functional bathroom units has accelerated the development of integrated bathing technologies. However, most existing solutions are either semi-automated or rely heavily on fixed plumbing installations and external infrastructures, making them less efficient in constrained or mobile living environments. Additionally, current devices often lack responsive safety features and personalized wellness options, such as stress monitoring or environmental feedback, which can significantly enhance the overall bathing experience.

[0003] Traditionally, bathing devices have been constructed using fixed enclosures with basic shower fittings and manually operated valves, offering limited flexibility or user interactivity. Steam functions, when available, are typically controlled through separate units and lack integration with user feedback or environmental responsiveness. These setups often fail to account for individual preferences such as ideal water temperature, steam levels, or real-time physiological conditions. Furthermore, existing bathing spaces do not adequately incorporate intelligent safety features, which are critical for users with specific health conditions or mobility limitations. Manual cleaning and drying after each session further reduce user convenience and hygiene.

[0004] US5564138A discloses a portable shower includes a base, a frame which is releasably attached to the base and which is provided by a plurality of releasably connected tubes, and a curtain which is supported by the frame. The base is formed from a pair of hingedly connected base portions which are pivotable between a shower position in which the base portions are co-planar to form a water-collecting basin and a storage position in which the base portions are superposed and form a storage case. The tubes of the frame and the curtain can be stored inside of the storage case.

[0005] US10327597B1 disclose a stand-alone shower device includes a cylindrical shower compartment with a transparent, translucent, or opaque wall and door, one or more specially configured shower nozzles, an optional storage compartment, and an optional surrounding cylindrical privacy curtain.

[0006] Conventionally, many devices designed for bathing have relied on fixed installations with limited adaptability, offering basic functionality without personalized features. These setups often lack automation, user-specific customization, and intelligent environmental responsiveness, resulting in reduced comfort, inefficient operation, and limited usability in diverse or space-constrained environments such as mobile or compact living spaces.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to offer a fully enclosed, adaptable, and intelligent bathing experience, capable of functioning independently while ensuring enhanced hygiene, user comfort, and operational efficiency across various environments without relying on fixed infrastructure or manual intervention.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a self-contained bathing device that is capable of delivering a controlled and enclosed bathing experience, offering improved hygiene, user comfort, and ease of use. The device further allows user-specific adjustments and maintains suitable conditions for a convenient and refreshing shower or steam bathing session.

[0022] Referring to Figure 1 & 2, an isometric view of a self-contained bathing device and an inner view of a pod associated with the device are illustrated, respectively, comprising a pod 101 constructed with a first and second vertically spaced concentric circular rings 102 interconnected by a plurality of vertically extendable links 103, a plurality of motorized roller units 104 mounted on the second circular ring 102 at top of the pod 101, a flexible multi-layered sheet 105 integrated on the roller units 104 comprises on inner mesh layer 105a, an intermediate fabric layer 105b, and an outer carbon mesh layer 105c, a circular base 201 positioned inside the pod 101 having a plurality of drainage holes 202, a motorized segmented door panel 106 comprising an electromagnetic locking unit 107 installed on a front side of the pod 101, a compartment 108 installed in a lower section of the pod 101 including a motorized water inlet valve 109 connected to a water source via a pipeline 110.

[0023] Figure 1 and 2 further illustrates an inverted L-shaped extendable hollow member 203 connected to the compartment 108, a shower panel 204 integrated with the hollow member 203, a steam generator 111 connected to the compartment 108 through a motorized valve 112, a multi-colored LED (Light Emitting Diode) light strip 205 arranged on the shower panel 204, a multi-joint two-bar linkage 206 connected to a wiper unit 207, an air blower unit 208 mounted inside the pod 101, a waterproof touchscreen control panel 209 mounted inside the pod 101, a plurality of fastening clamps 113 are attached to a lower edge of the sheet 105, a wearable wristband 114 linked wirelessly to the device, a multi-section nutrient infuser section 115 connected to the compartment 108, a camera 116 mounted on the outer surface of the pod 101, a spraying unit 117 installed on outer surface of the pod 101.

[0024] The device disclosed herein comprises of a pod 101 constructed with a first and second vertically spaced concentric circular rings 102. The rings 102 operate as a vertically aligned structural frameworks where the lower ring remains fixed and the upper ring is elevated or lowered through a plurality of vertically extendable links 103, enabling dynamic adjustment of the pod’s height to accommodate different user sizes and preferences. The pod 101 being configured to enclose a user during a shower or steam bath session.

[0025] For initiating functionality of the device, the user manually presses a push-button installed on the pod 101. The push button serves as the primary means for turning the device on and off. The push button is typically made from polycarbonate. When push button is pressed to switch on the device it allows current to flow. This sends a signal to the device's microcontroller, instructing it to activate the device. The microcontroller then powers up the device, enabling them to function.

[0026] The concentric circular rings 102 are interconnected by the plurality of vertically extendable links 103 which makes the pod 101. The extendable links 103 comprises linear actuators interconnecting the first and second concentric rings 102. Each links 103 includes an inner sliding shaft housed within an outer sleeve, actuated via miniature motors. Upon activation by the microcontroller, the motors extend or retract the inner shafts, thereby adjusting the vertical spacing between the rings 102. Limit sensors within the links 103 monitor extension length to prevent overextension. The links 103 are adjustable in length to vary distance between the rings 102 and adjust the height of the pod 101 based on the height of the user as detected via an integrated ultrasonic sensor.

[0027] The ultrasonic sensor comprises a transmitter and a receiver housed within the pod’s upper section. The transmitter emits high-frequency sound waves directed downward toward the user. These waves reflect off the user's head or shoulders and return to the receiver. The sensor measures the time delay between transmission and reception, calculating the user's height based on the speed of sound. This height data is transmitted to the microcontroller, which adjusts the vertically extendable links 103 of the pod 101 to set an optimal enclosure height around the user.

[0028] After adjusting the vertical space, the microcontroller actuates a plurality of motorized roller units 104 mounted on the second ring 102 on the top of the pod 101 to roll a flexible multi-layered sheet 105 inward to cover the pod 101. Each motorized roller unit 104 consists of a cylindrical drum connected to a compact electric motor with a gear reduction means to control rotation speed and torque. The flexible multi-layered sheet 105 is wound around the drum, and when the motor is activated by the microcontroller, it rotates the drum to either roll the sheet 105 outward for enclosure or retract it inward for opening. Rotary encoders are integrated to monitor the rotational position, ensuring precise deployment length.

[0029] The flexible multi-layered sheet 105 comprises three layers – an inner mesh layer 105a made of heat-resistant synthetic material allowing airflow while preventing direct contact with steam. An intermediate fabric layer 105b formed of PVC (Polyvinyl Chloride)-laminated cloth for steam retention and privacy, and an outer carbon mesh layer 105c for external tamper resistance and enhanced thermal insulation.

[0030] A plurality of fastening clamps 113 are attached to a lower edge of the sheet 105 for securing the sheet 105 to the pod 101 structure, ensuring a tight and stable enclosure during operation. Each fastening clamp 113 includes a spring-biased jaw assembly positioned along the lower edge of the flexible multi-layer sheet 105. The jaws are structured to engage with fixed anchoring projections on the pod 101. Upon full extension of the sheet 105, position sensors transmit a signal to the microcontroller, which activates the actuators to close the jaws over the projections, thereby securing the sheet 105. The clamps 113 remain in a locked state until a release signal is provided, following which the jaws disengage to permit sheet 105 retraction.

[0031] For stable standing of the user, a circular base 201 positioned inside the pod 101 for providing stable footing. The base 201 having a textured upper surface to prevent slipping and a plurality of drainage holes 202 for discharging water droplet. The circular base 201 is constructed from a high-strength, water-resistant polymer composite, featuring the textured upper surface melded with anti-slip patterns to ensure user stability during use. Internally, the base 201 integrates structural ribs for load distribution and is slightly sloped to channel water toward strategically placed drainage holes 202.

[0032] The plurality of drainage holes 202 is connected to a network of internal ducts that guide wastewater toward an underlying drainpipe. These holes 202 are fitted with fine mesh filters to prevent hair and debris from clogging the device. A passive gradient ensures gravity-assisted flow, while optional check valves within the ducts prevent backflow. The drainage network ultimately routes water to an external outlet water collection unit for disposal.

[0033] To allow smooth entry and exit of the user, the microcontroller actuates a motorized segmented door panel 106 installed on a front side of the pod 101 for vertical articulation. The motorized segmented door panel 106 consists of interlocking curved segments guided along vertical tracks embedded within the pod 101. A compact linear actuator drives the segments upward or downward, allowing smooth opening and closing. Each segment is linked via hinges, enabling a foldable motion. Limit switches detect fully open or closed positions.

[0034] The door panel 106 further comprising an electromagnetic locking unit 107 to secure the interior and retain steam during operation. The electromagnetic locking unit 107 comprises an electromagnet embedded in the pod 101 and a ferromagnetic plate attached to the door panel 106. When the door closes, the microcontroller energizes the electromagnet, creating a magnetic field that securely attracts and holds the armature, locking the door in place. A built-in sensor confirms lock engagement. During power-off or emergency override, a spring-loaded release means allows manual disengagement. This door panel 106 ensures airtight sealing during operation, particularly for steam retention, while providing safety and control through electronic regulation.

[0035] A compartment 108 installed in a lower section of the pod 101 for water storage and heating. The compartment 108 includes a motorized water inlet valve 109 connected to a water source via a pipeline 110 and configured to open automatically in response to water level detection. The compartment 108 is a sealed, insulated unit and includes an internal reservoir. A Peltier unit coupled with a temperature sensor integrated within the compartment 108 to heat water to a desired temperature. The Peltier unit operates using thermoelectric modules composed of n-type and p-type semiconductor elements. When electric current passes through the unit, heat is absorbed on one side (cooling) and dissipated on the other (heating). The heated side contacts the water reservoir, efficiently warming water to a desired temperature.

[0036] To monitor the water level inside the compartment 108, the microcontroller activates a level sensor installed inside the compartment 108 based on which the microcontroller actuates a motorized pump embedded with the compartment 108 to maintain a predefined water level inside the compartment 108. The motorized water inlet valve 109 consists of a solenoid connected to a valve gate within the pipeline 110. When the microcontroller detects a low water level via the level sensor, it sends a signal to the actuator to rotate or lift the valve gate, allowing water to flow into the compartment 108. The actuator includes position feedback sensors to ensure precise opening and closing. Once the desired water level is reached, the microcontroller signals the actuator to close the valve, maintaining accurate and automated water control.

[0037] Further, an inverted L-shaped extendable hollow member 203 connected to the compartment 108 to channel heated water or steam upward towards a shower panel 204 integrated with the hollow member 203. The extendable hollow member 203 is basically an inverted L-shaped conduit composed of telescopic cylindrical sections that slide within each other, allowing vertical extension and retraction. Internally, it features a heat-resistant, flexible water and steam delivery pipe running through the hollow sections. A motorized linear actuator, controlled by the microcontroller, drives the extension based on user height or preset settings. Sealed rotary couplings ensure continuous fluid flow without leaks during movement, enabling precise and adjustable delivery of heated water or steam to the shower panel 204.

[0038] The shower panel 204 integrated with the hollow member 203 contains an internal network of micro-channels connected to the hollow member’s fluid outlet, allowing uniform distribution of heated water or steam. Inside the panel, a pressure-regulated nozzle array disperses the fluid through multiple adjustable jets, enabling varied spray patterns such as mist, rainfall, or pulse.

[0039] A steam generator 111 connected to the compartment 108 through a motorized valve 112 where heated water is selectively directed to the steam generator 111 to be converted into steam which is then released inside the pod 101 in response to the user command. When the microcontroller receives a user command for steam, it actuates the valve to open, allowing heated water to flow from the compartment 108 into the steam generator 111 chamber. Inside the chamber, electrical heating coils rapidly convert the incoming water into steam. A temperature and pressure monitoring unit regulates the conversion process. Once steam is formed, it is directed through a dedicated outlet channel into the enclosed pod 101 to begin the steam bath session.

[0040] A multi-colored LED (Light Emitting Diode) light strip 205 integrated with a temperature sensor arranged on the shower panel 204. The microcontroller operatively connected with the sensor and LED strip 205 change the LED color accordingly to visually indicate current water temperature. The temperature sensor consists of a thermistor that varies its electrical resistance based on the surrounding fluid temperature. This resistance change is measured by the microcontroller, which calculates the corresponding temperature through an internal calibration curve and uses this data to actuate the multi-coloured LED light strip 205.

[0041] The light strip 205 is composed of addressable RGB LEDs embedded within a protective waterproof casing along the shower panel 204. Each LED receives input signals from the microcontroller, which adjusts the red, green, and blue channels to display a specific colour corresponding to the sensed water temperature. For example, blue indicates cold, green indicates warm, and red indicates hot. The strip 205 dynamically updates in real-time, providing the user with a visual indication of current water conditions without requiring physical contact.

[0042] Furthermore, a multi-joint two-bar linkage 206 connected to a wiper unit 207 to automatically cleans water droplets from the pod 101 surface after shower completion. The multi-joint two-bar linkage 206 consists of two rigid arms connected by a central pivot and mounted between the pod 101 surface and the wiper unit 207. One end of the first arm is fixed to a motor shaft, while the other end is pivotally linked to the second arm, which is attached to the wiper. Upon activation by the microcontroller, the motor rotates the first arm, causing the second arm to follow a defined path across the pod’s inner surface. This coordinated movement ensures complete coverage and consistent wiper motion. The wiper unit 207 comprises a curved, soft-edged blade designed to conform to the pod’s interior contour, effectively sweeping away water droplets and residual moisture after shower completion.

[0043] An air blower unit 208 is mounted inside the pod 101 to dry the user’s body after bath completion, operable manually via user’s voice commands. The blower unit 208 consists of a high-speed electric motor connected to a centrifugal fan housed within a noise-insulated casing. When activated via voice, the microcontroller drives the motor to rotate the fan, drawing ambient air through an intake filter and forcing it through a heating coil. The heated air is then expelled through a directional nozzle positioned inside the pod 101. The microcontroller regulates fan speed and air temperature based on user preferences, ensuring efficient drying of the user’s body after the shower session.

[0044] Additionally, a waterproof touchscreen control panel 209 is mounted inside the pod 101, serving as the central interface for operating and customizing features, operable with wet or steamy hands. The waterproof touchscreen control panel 209 is integrated within the pod’s interior and enclosed in a sealed casing made of moisture-resistant, impact-rated material such as polycarbonate with a capacitive touch-sensitive surface. Internally, the panel includes a microprocessor, memory unit, display controller, and a communication interface linked to the central microcontroller. The capacitive layer detects finger contact even under wet or steamy conditions by sensing electrical variations caused by the user's touch. The processor interprets these inputs and executes corresponding commands, such as activating features, adjusting settings, or displaying operational status. Real-time feedback, icons, and alerts are rendered on the screen for user interaction.

[0045] A wearable wristband 114 is linked wirelessly to the device, including a GSR sensor for monitoring user’s stress and thermal conditions to auto-adjust safety settings upon detection of abnormal physiological readings. The wearable wristband 114 is constructed with a flexible, waterproof housing containing a wireless communication module, rechargeable power unit, and sensor interface. It continuously transmits physiological data to the pod’s microcontroller and allows real-time user monitoring during bathing sessions, ensuring automated safety adjustments based on biometric inputs.

[0046] The GSR (Galvanic Skin Response) sensor embedded in the wristband 114 measures changes in skin conductivity caused by sweat gland activity, which correlates with stress or thermal changes. It includes two electrodes placed on the inner wrist that apply a low-voltage current and detect resistance variations. These signals are amplified and digitized, then sent to the microcontroller, which interprets them to assess the user’s stress levels or abnormal conditions, prompting automated adjustments such as temperature reduction or early shutdown.

[0047] Based on the user’s skin type detected via the GSR sensor, the microcontroller activates a multi-section nutrient infuser section 115 connected to the compartment 108 for selectively dispensing nutrient liquids. The multi-section nutrient infuser section 115 includes multiple sealed chambers, each pre-filled with specific nutrient liquids suitable for different skin types. Solenoid-controlled valves are assigned to each chamber and are connected to a common outlet linked to the water flow line. Upon receiving input from the GSR sensor, the microcontroller identifies the appropriate chamber and actuates the corresponding valve, releasing a precise volume of nutrient liquid into the water stream. This enables customized skin nourishment during the shower or steam session.

[0048] Further, a camera 116 is mounted on the pod’s outer surface for continuously monitoring for unauthorized interference by humans or animals. The camera 116 includes a wide-angle lens, image sensor (such as CMOS), and a digital signal processor housed in a weather-resistant casing. It captures continuous video feed or still images of the surrounding environment. The image data is processed to detect motion or identify human or animal presence using predefined pattern recognition protocols. Upon detection, the camera 116 sends signals to the microcontroller, which triggers a spraying unit 117 provided on outer surface of the pod 101 to repel animals, and also triggers alerts including image capture and notifications to authorities upon detecting human tampering.

[0049] The spraying unit 117 includes multiple sealed compartments; each filled with a distinct non-harmful fragrance liquid. These compartments are connected via micro-channels to a telescopic hollow rod fitted with an ultrasonic atomizer at its outlet. Upon receiving a signal from the microcontroller after animal detection by the camera 116, a solenoid valve corresponding to the selected fragrance opens, allowing liquid to flow into the atomizer. The atomizer converts the liquid into a fine mist using high-frequency vibration. Simultaneously, the telescopic rod extends outward, directing the mist toward the animal, ensuring effective deterrence without causing harm or distress.

[0050] The present invention works best in the following manner, where the user enters the pod 101 structure formed by the concentric rings 102, with the flexible multi-layered sheet 105 fully extended and secured in place using the plurality of fastening clamps 113 at the lower edge. The user operates the waterproof touchscreen control panel 209 mounted on the interior surface of the pod 101, which responds even under wet or steamy conditions. Upon command, the microcontroller initiates water inflow through the motorized inlet valve 109 into the compartment 108, where the Peltier unit heats the water to the desired temperature as detected by the temperature sensor. The heated water flows through the extendable hollow member 203 into the integrated shower panel 204, from which it is sprayed via pressure-regulated nozzles.

[0051] In continuation, the temperature sensor simultaneously sends real-time data to the microcontroller, which alters the color of the multi-coloured LED light strip 205 accordingly to indicate current water temperature. During steam mode, the microcontroller opens the motorized valve 112 to transfer heated water into the steam generator 111, which converts it into steam and releases it inside the pod 101. The ultrasonic sensor detects the height of the user, prompting the microcontroller to adjust the vertically extendable links 103 for optimal enclosure height. Throughout the session, the wearable wristband 114 transmits physiological data via wireless communication, including stress signals detected by the GSR sensor. If abnormal readings are identified, the microcontroller automatically adjusts temperature or activates safety overrides. Upon session completion, the multi-joint two-bar linkage 206 connected to the wiper unit 207 performs surface cleaning of the pod 101 interior, and the air blower begins to emit warm air to dry the user's body. The camera 116 mounted externally continues monitoring for any unauthorized presence, and if the animal is detected, the microcontroller activates the spraying unit 117 to release non-harmful fragrance mist from the selected fragrance liquid compartment to deter the animal.
