Description:A STAIN REMOVAL DEVICE
DESCRIPTION
Technical Field
[001] This disclosure relates generally to washing devices, and more particularly to a stain removal device.
Background
[002] Fabric care or washing machines are designed to wash away stains on the cloth uniformly, irrespective of the depth of the stains. Wash quality depends on multiple parameters such as water hardness, quality of the detergent, drum revolutions, wash time, volume of clothes put for washing, etc. Washing machines may work well in most of the cases, but not all the time. Washing machines may depend on hard chemicals or expensive detergents as a washing cycle cannot differentiate the stain spots from the rest of the cloth area while washing inside a drum.
[003] Hard (or deep) stains, including hard collar stains, may need a special attention. In the present state of art, the hard stains may be treated manually by hand scrubbing and rarely practiced due to time consumption, hands getting wet, washroom floor getting wet, and clumsy experience. At times, people may go for a laundry wash to get hard stains removed since they don’t have time and patience to get the stain off the clothes at home, even though they have access to washing machines. This is a laborious process which requires a lot of human effort and additional space in the house. Therefore, there is a need for a device to address these drawbacks in order to provide convenience to the people to frequently and efficiently remove hard stains from the clothes.
[004] The present invention is directed to overcome one or more limitations stated above or any other limitations associated with the known arts.

SUMMARY
[005] In one embodiment, a stain removal device is disclosed. In one example, the stain removal device may include a brush housing. The stain removal device may further include at least one brush assembly enclosed within the brush housing. It should be noted that each of the at least one brush assembly may include a cylindrical brush body. The cylindrical brush body may be rotatable about a rotation axis. It should also be noted that each of the at least one brush assembly may further include replaceable bristles covering the cylindrical brush body.

[028] It is worth noting that the at least one motor is a part of the brush assembly 104. This is explained in greater detail in conjunction with FIG. 4. Optionally, the stain removal device 100 may further include a water inlet (not shown in figure). The water inlet is configured to supply water to one of the brush housing 102 or the cleansing solvent chamber 110 from a water source. The supplied water may be mixed with the cleansing solvent. The water inlet may be made by using materials such as, plastic, etc. The stain removal device 100 may further include a clip mechanism (not shown). The clip mechanism may be affixed to one of the brush housing 102 or the tray assembly 114. It should be noted that the clip mechanism is configured to hold the stained object in place in the washing slot 112 during the washing operation.
[029] In an exemplary scenario, the user may want to remove hard stain (e.g., a stain of ink) from the cloth (e.g., a shirt). For this, initially the user may insert the stained portion of the shirt in the washing slot 112 and secure the stained portion via the clip mechanism (such as plastic fasteners). Further, the user may pour the cleansing solvent (e.g., liquid washing detergent) in the cleansing solvent chamber 110. At the time of pouring, the dispensing slots of the cleansing solvent chamber 110 may be in the closed configuration. Further, the user may turn on the power supply to the stain removal device 100. The user may further select the rotational speed level of the brush assembly 104 through a controller (e.g., a regulator) as per user requirements. When selecting the speed level, the user may consider factors such as type of the fabric (e.g., shirt), type of stain, intensity of the stain, or the like. In some embodiments, the rotational speed level of the brush assembly 104 may be automatically adjusted as per the fabric type.
[030] Upon selecting the rotational speed level of the brush assembly 104, the dispensing slots may switch from the closed configuration to the open configuration to dispense the cleansing solvent (e.g., liquid detergent) on the brush assembly 104. Further, the brush assembly 104 may start rotating over the stained portion of shirt. Further, the replaceable bristles 108 of the brush assembly 104 may scrub over the stained portion to remove the hard stain (i.e., ink stain) from the shirt.
[031] Further, the tray assembly 114 may collect the run-off cleansing solvent from the brush assembly 104 continuously during the washing operation through the one or more drainage pores. The one or more drainage pores of the tray assembly 114 may drain the run-off cleansing solvent from the stain removal device 100. The stain removal device 100 may include an outlet 116 to remove the run-off cleansing solvent collected within the tray assembly 114. In some embodiments, upon completion of the washing operation, the user may or may not put the shirt in the washing machine for the regular washing.

The at least one dispensing slot (such as a dispensing slot 118) is located on an adjoining surface between the brush housing 102 and the cleansing solvent chamber 110. The opening and closing of the at least one dispensing slot may be controlled through a valve. When each of the at least one dispensing slot is in the closed configuration, the cleansing solvent may remain within the cleansing solvent chamber 110. When at least one dispensing slot (such as the dispensing slot 118) is in the open configuration, the cleansing solvent may pass through the at least one dispensing slot from the cleansing solvent chamber 110 to the brush housing 102. Ultimately, the cleansing solvent is dispensed on the surface of the replaceable bristles 108.
[033] Additionally, the one or more drainage pores (such as a drainage pore 120) are located on a surface of the tray assembly 114 that acts as the washing platform in the washing slot 112. The one or more drainage pores are configured to drain the run off cleansing solvent from the washing slot 112 into the tray assembly 114. In some embodiments, the one or more drainage pores may not be required. In such embodiments, there may be an alternate drainage mechanism (such as a wiper assembly to wipe the run off cleansing solvent from the washing platform, mesh-like washing platform surface of the tray assembly 114 to allow collection of the runoff cleansing solvent, etc.).
