Description: A MIXER GRINDER WITH SENSING MECHANISM AND A METHOD OF WORKING THEREOF

FIELD OF THE INVENTION
[0001] The present disclosure relates to a mixer grinder with sensing mechanism. The present disclosure also relates to a method of working of a mixer grinder with sensing mechanism. More particularly, the present disclosure relates to a mixer grinder with sensing mechanism. The sensing mechanism senses the lid to jar and jar to base connection.

BACKGROUND OF INVENTION
[0002] In general, a mixer grinder consists of a motor base unit, jars (n nos.) and corresponding lid of jars. Normally during grinding or any other mixing operation through mixer grinder, the jar (containing material to be grinded) with lid closed manually, is placed over the base unit where the jar coupler gets engaged with motor unit coupler and then only mixer grinder power should be turned ON to perform required grinding operation. However, there are specific scenarios which can make the mixer grinder operation un-safe:
• If lid & jar is not properly connected. There is tendency of spillage,
• If jar & base unit is not properly connected
• Jar is connected, but lid loosen – Spillage problem
• Lid & jar is connected but jar & base unit not connected- coupler or product damage.
• A person is pouring the material in jar and mistakenly switch ON the unit
[0003] CN113811235A titled as “Food Processor”, relates to a food processor which can sense whether a cover is closed or not by transmitting an electric signal through a transparent film. The food processor of the invention comprises: a container for containing food; a body disposed at a lower side of the container and supporting the container, a cover detachably attached to the top surface of the container to open and close the upper part of the container; and a sensing system sensing whether the cover is mounted to the container, the sensing system including a transparent electrode film attached to a surface of the container and guiding a flow of electricity. Therefore, there is an advantage that whether or not the lid is attached or detached can be transmitted to the body without affecting the appearance of the container made of the transparent material. However, due to guiding a flow of electricity may lead to electrical shock during the usage of food processor. Thus the processor is not safe to use.
[0004] In addition, in the US patent publication US7871196, a link for transferring the closing of the lid to the upper and lower sides of the container is provided inside the handle of the container, not at the side of the container. Namely, it is realized in the following manner: a push rod (push rod) disposed long up and down is disposed into a groove (groove) inside the handle to move the push rod (push rod) to a lower side by closing the cover from an upper side, so that a lower switch disposed at the lower side is activated by the push rod (push rod) to sense the cover. However, in this patent, a separate pressing member or push block (push block) or the like needs to be provided, and a link or push rod (push rod) formed long up and down needs to be provided according to the length, and thus, not only is it difficult to manufacture and assemble, but also there are problems in that: a sensing function loss due to wear or breakage caused by frequent use, and a non-sensing (signal transmission is not possible) caused by twisting or bending of a link or a push rod (push rod) having a relatively long length, or the like.
[0005] US10357749B2 titled as “Container/lid/blender interlock”, discloses an interlocking method and blending apparatus is provided which includes a base, container, and lid. The apparatus comprises light emitters, light sensors, and light reflectors. Light is emitted by the light emitters from the base, through the container, and toward the lid. Light reflectors in the lid reflect the light back through the container and toward the base. The light sensors detect the reflected light and can be used to control operation of the blender and illumination of the container. Light may be in the visible spectrum, or sub-visible spectrum. The light emitters and light sensors may be at the base and/or the bottom of the container. In this blender, the light is required to travel a long path starts from base and end to base, which require a proper obstacle free path. Any damage or minor discrepancy in the path would obstruct the light to travel and thus the purpose of the blended would be defeated.
[0006] US6629492B1 titled as “Juicer having a safe power connection” function as a juicer having a safe power connection function includes a motor seat, a fixing ring, a container, an electric wire, a conductive switch, and a top cover. Thus, when the top cover is not mounted on the top of the container rigidly and stably and when the press member of the conductive switch is not in contact with the conductive member of the conductive switch, the motor will not be driven to operate, so as to prevent the cutter blades from being rotated due to unintentional touch of the control switches, thereby preventing the user from being injured, and thereby protecting the user's safety.
[0007] Currently the solution present in the market alternative involves mechanical linkages and micro-switches which need efforts to close the lids and have the mechanical hassles. The technique disclosed in the prior arts has the issues like break down & jamming of the levers.

On the contrary, a variety of optional components are described to illustrate the wide variety of possible embodiments of the present disclosure.
[0037] To overcome the drawbacks of prior arts, ensure accidental scenarios not to occur, a technology employing smart sensing and wireless connection feature is introduced in the mixer grinder and discussed in the present disclosure where the base unit will get operational only when a proper orientation and connection is established between lid, jar and base unit. This smart feature is enabled through electronics module which increases the consumer comfort and product reliability via this invention in comparison to mechanical solutions (mechanical linkages using lever & micro switch) already available in the market. The main attribute of this invention is the wireless sensing of lid to jar with the help of a magnet and jar to base unit with the help of IR sensor module which reduces the locking discomfort experienced due to mechanical linkages.
[0038] In the present invention, as part of lid which comes in contact with the jar upon connection, is provided with a magnet. On placing and connecting the lid over jar, the magnet will activate the reed switch. In the handle the reed switch, a battery and an IR generator is provided in a series connection.

Also a lid 200 detachably mounted on the open end of the jar 300. The lid 200 having a magnet M 210 disposed upon at least a portion on circumferential portion of the lid 200. The mixer grinder 100 has a base 500 having a motor 510 and a bore to secure the jar 300 by receiving the bottom end of the jar and a power supply to provide power to the motor 510.
[0042] In the mixer grinder as disclosed by the present disclosure, the handle 400 comprises a sensing mechanism configured to sense the connection between the lid 200 and the jar 300 and provide a signal to the base 500. The sensing mechanism has a light spectrum generator 431 placed at the lower portion 430 of the handle 400, a battery 421 surrounded by the vertical portion 420 of the handle 400 and occupied a part of lower portion 430 of the handle 400 and a reed switch (411) positioned at the upper portion 410 of the handle 400. The base comprises a light spectrum detector 520, configured to provide power to the motor 510 when the signal sent by the sensing mechanism is received by the light spectrum detector 520.
[0043] The reed switch 411 gets activation upon coupling with the magnet M 210, when the lid 200 mounted on the jar 300 and get engaged with the jar 300. Here the battery 421 is provided to provide power to the light spectrum generator 431 through the reed switch 411. Thus, upon activation of the reed switch, the circuit between the reed switch 411, battery 421 and the light spectrum generator 431 become closed and the light spectrum generator 431starts receiving power from the battery 421 and thus generates signal in the form of light spectrum. The circuit is shown in Fig. 2.
[0044] The light spectrum detector 520 is provided on the surface of the base and when the jar is secured with the base, the light spectrum detector 520 and the lower portion 430 of the handle 400 are in a straight line. Thus, the light spectrum detector 520 receives the signal sent by the light spectrum generator 431. Upon receiving light, the secure connection between the lid 200 and jar 300 and jar 300 to base 500 is ensured and the base starts sending power to motor 510 for operation.
[0045] In an embodiment of the mixer grinder disclosed in the present disclosure, the vertical portion 420 has projections for the fingers to hold the handle 400 by user. The light spectrum generator 431 may be an IR generator and the light spectrum detector may be an IR detector. The mixer grinder 100 also may has a plurality of LED which get activation upon secure connection of lid 200 with jar 300 and the base 500 has a plurality of LED and buzzer which get activation upon secure connection of jar 300 with base 500.

TECHNICAL ADVANTAGES
[0046] This will enhance customer safety by not letting the whole unit to operate without proper alignment and connection is established between lid to jar and jar to base unit.
[0047] The customer will experience a spillage free operation of mixer grinder, in case the lid of jar loosen up.
[0048] The present disclosure discloses a major shift from mechanical to electronic based solution which reduces the customer’s effort in aligning the jar and base unit for proper assembly. Instead of using a mechanical contact, we will use a wireless contact for Lid to Jar and Jar base to Base unit connection thereby generating the comfort to users and introducing automation. It assists in reduction of number of parts and elimination of complicated mechanism (through wireless solution).
[0049] Base unit will not turn ON unless the Lid to Jar and Jar base to base unit contacts are securely established. It will ensure safe operation of mixer grinder. Connection will be established using Magnet, Reed switch, IR transmitter & receiver using battery power. It uses the AND logic to function and provide safety feature in mixer grinder.
