Description

Technical Field

[0001] The present invention relates to the technical field of kitchen household appliances, and in particular to kitchen waste processing equipment. Background Art

[0002] A variety of food waste may be generated in the kitchen, such as small pieces of pork bones, chicken bones, fish bones, eggshells, melon peels, fruit peels and cores, tea leaves, vegetable roots and leaves, coffee grounds, leftovers, soup scraps, and bread crumbs. A food waste disposer is a device installed at the garbage outlet of a kitchen sink or under the kitchen sink. It can conveniently discharge food waste into a pipe or grind it into fine particles or a slurry, which is then discharged naturally through a pipe with water. A food waste disposer is usually connected to a garbage pipe to immediately and conveniently dispose of all food waste, achieving a clean environment and eliminating odors. It can also reduce kitchen odors, reduce pest infestation, and promote family health.

[0003] In the prior art, a food waste disposer uses a drive mechanism to rotate a grinding element within a grinding chamber. The rotation of the grinding element grinds and pulverizes the food waste, turning it into a powder or small particles that flow into the sewer along with the water. Once the waste is pulverized by the grinding element, it enters the waste discharge pipe through the narrow gaps within the grinding element. The remaining waste in these gaps can easily breed bacteria, which, if left untouched, can produce odors. Summary of the Invention

[0004] In view of this, the present invention provides a kitchen waste treatment device to solve the problem that the kitchen waste remaining in the grinding chamber is prone to breeding bacteria.

[0005] The present invention provides a kitchen waste treatment device, comprising: a shell, enclosing a grinding chamber; a grinding disc, arranged in the grinding chamber, and capable of grinding the kitchen waste entering the grinding chamber by rotating; a heating component, comprising a first heating part, the first heating part being arranged on the shell, and the first heating part surrounding the grinding chamber and arranged relative to the grinding disc to heat the edge of the grinding disc.

[0006] By arranging the first heating part in a circular manner on the shell, and the first heating part is opposite to the edge of the grinding disk, the projection of the first heating part on the inner wall of the shell covers the projection of the grinding disk on the inner wall of the shell, so that the first heating part can heat the shell after starting the heating, thereby transferring the heat to the grinding disk and completely heating the garbage on the grinding disk through the groove, so that the garbage remaining in the groove can be disinfected and sterilized, thereby avoiding or reducing the breeding and reproduction of bacteria and avoiding the generation of odor.

[0007] In an optional embodiment, the first heating part is a coil, and the food waste treatment equipment also includes a magnetic flux change generating device, which is partially arranged on the grinding disk, so that the process of synchronous rotation of the magnetic flux change generating device and the grinding disk can generate alternating current in the coil to generate heat.

[0008] By placing the multi-turn coil in an annular cavity, the safety of the coil during use can be guaranteed. The first heating unit is installed in the annular cavity. The gas in the annular cavity acts as a medium to quickly transfer heat to the shell, which in turn allows the generated heat to be transferred more quickly to the inner wall of the shell, thereby improving thermal efficiency. By changing the magnetic flux entering the coil, alternating current is generated in the coil. When alternating current is generated in the coil, the coil can generate heat, and the heat generated by the coil can heat the shell.

[0009] In an optional embodiment, the magnetic flux change generating device includes: a magnetic connector, provided on the grinding disk; a magnet, including a south magnetic pole and a north magnetic pole, and the south magnetic pole and the north magnetic pole are arranged in a circumferential direction in sequence; wherein, the magnetic connector contacts the south magnetic pole and the north magnetic pole in sequence during the synchronous rotation of the grinding disk.

[0010] The magnetic connector can rotate synchronously with the grinding disk. By placing the magnet on the movement trajectory of the magnetic connector, the magnetic connector can alternately contact the south and north poles of the magnet, thereby changing the change of the magnetic flux entering the coil and generating alternating current in the coil.

[0011] In an optional embodiment, the magnet is provided in plurality, and the plurality of south magnetic poles and the north magnetic poles are arranged alternately in a circumferential direction.

[0012] By setting up multiple magnets and arranging multiple south magnetic poles and north magnetic poles alternately in a circumferential direction, and increasing the contact frequency of the magnetic connector with the south magnetic pole and the north magnetic pole, the alternating current generated in the coil can be increased. The magnetic connector alternately contacts the south magnetic pole and the north magnetic pole, so that the magnetic fields of the south magnetic pole and the north magnetic pole are alternately enhanced by the magnetizer, and the coil generates an induced current due to the change in magnetic flux.

[0013] In an optional embodiment, the magnetic connector is provided at the bottom of the grinding disc, and the magnet is provided below the grinding disc.

[0014] By arranging the magnetic connector at the bottom of the grinding disc and the magnet below the grinding disc, it is easier for the magnetic connector to alternately contact the south pole and the north pole of the magnet.

[0015] In an optional embodiment, the magnetic connector is provided at the edge of the grinding disc, and the magnet is provided on the housing. By providing the magnetic connector at the edge of the grinding disc and the magnet on the housing, the area used for the magnet and the magnetic connector can be reduced, thereby reducing costs.

[0016] In an optional embodiment, the food waste treatment device further includes a controller, the controller includes a detection module, and the detection module is electrically connected to the coil, so that the controller can detect the current of the coil through the detection module.

[0017] The controller detects the alternating current generated by the coil. When the driving device drives the grinding disc to rotate at speed a, there should be an induced current I a When garbage blocks the grinding disc, if the induction current detected by the detection circuit of the controller is not I a , indicating a stall. In this case, the drive unit can be controlled to stop to prevent damage and reduce the service life of the food waste treatment equipment. Therefore, the controller detects the induced current generated by the coil and can use the detected current to determine the rotation speed of the grinding disc. This can determine whether the grinding disc's rotation speed is normal, avoid stalls, and thus extend its service life.

[0018] In an optional embodiment, the food waste treatment equipment further includes a power storage device, which is electrically connected to the coil and connected to the controller, so that the controller can control the power storage device to store electrical energy.

[0019] The electrical energy of the induced current generated by the coil can be stored by the electrical storage device, thereby recovering the energy. The electrical storage device can be realized by existing technologies and will not be described in detail here.

[0020] In an optional embodiment, the food waste disposal equipment also includes a warning module electrically connected to the controller, the detection module includes a detection circuit, and the warning module is electrically connected to the detection circuit so that when the current detected by the detection circuit does not match the preset current, the warning module sends an alarm signal.

[0021] The induced current generated by the coil is detected by the detection circuit, and a warning signal is sent out through the warning module to display and prompt whether there is a stall in real time through the screen, sound, etc.

[0022] In an optional embodiment, the shell is provided with a garbage discharge port connected to the grinding chamber, the garbage discharge port is connected to a garbage discharge pipe, and the heating component further includes a second heating part, which is provided in the garbage discharge pipe.

[0023] By arranging the second heating part on the garbage discharge pipe, the second heating part can heat the garbage discharge pipe after starting heating, thereby heating the inner wall of the garbage discharge pipe to reduce garbage adhering to the inner wall of the garbage discharge pipe, or sterilize the residual garbage adhering to the inner wall of the garbage discharge pipe to further reduce the growth of bacteria in the garbage discharge pipe.

[0024] The second heating unit is electrically connected to the detection circuit of the controller, making the detection of stall more reliable. For example, if the coil of the first heating unit is damaged, if the AC current generated by the second heating unit is detected to be inconsistent with the current required for the normal speed of the motor, then a stall can be determined.

[0041] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0042] The following combination Figures 1 to 8 , describing embodiments of the present invention.

[0043] like Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, on the one hand, a kitchen waste treatment device is provided, including: a shell 11, a grinding disc 12 and a heating component 13, the shell 11 encloses a grinding chamber, the grinding disc 12 is arranged in the grinding chamber, and the grinding disc 12 rotates to grind the kitchen waste entering the grinding chamber, and the heating component 13 includes a first heating part 131, the first heating part 131 is arranged on the shell 11, and the first heating part 131 surrounds the grinding chamber and is arranged relative to the grinding disc 12 to heat the edge of the grinding disc 12.

[0044] The projection of the first heating portion 131 on the inner wall of the housing 11 covers the projection of the grinding wheel 12 on the inner wall of the housing 11 .

[0045] The top of the housing 11 is open, so that food waste can enter the grinding chamber through the top opening of the housing 11. The housing 11 is provided with a water inlet, which is connected to the grinding chamber and can be connected to a water inlet pipe, so that water can be fed into the grinding chamber through the water inlet.

[0046] The grinding disc 12 is a disc-shaped structure with a certain thickness. The edge of the grinding disc 12 is provided with a garbage passing groove, and there are multiple garbage passing grooves. The edge of the grinding disc 12 is arranged close to the inner wall of the grinding chamber, that is, there is a gap between the edge of the grinding disc 12 and the inner wall of the shell 11. The gap is small to prevent garbage entering the grinding chamber from falling without being ground.

[0047] The grinding disc 12 rotates to grind the garbage, and after being ground, the garbage passes through the edge of the grinding disc 12 and falls through the slot.

[0048] The first heating portion 131 is arranged in a circular manner on the shell 11, and the first heating portion 131 is opposite to the edge of the grinding disc 12, so that the first heating portion 131 can heat the shell 11 after starting the heating, thereby transferring the heat to the grinding disc 12 and heating the garbage on the grinding disc 12 through the groove.

[0049] The projection of the first heating part 131 on the inner wall of the shell 11 covers the projection of the grinding disc 12 on the inner wall of the shell 11, so that the first heating part 131 can completely heat the garbage passing groove of the grinding disc 12 after starting the heating, thereby disinfecting and sterilizing the garbage remaining in the garbage passing groove, avoiding or reducing the growth and reproduction of bacteria, and avoiding the generation of odor.

[0050] Specifically, a drive device is provided below the grinding disc 12 to rotate the grinding disc 12 to grind the garbage. The housing of the drive device has an inclined surface, so that garbage falling from the grinding disc 12 through the groove falls onto the inclined surface and is then discharged from the grinding chamber through the garbage discharge port provided on the housing 11.

[0051] The driving device can be a motor 15, such as Figure 2 As shown, the motor 15 is disposed below the grinding disc 12 , and the motor 15 is connected to the grinding disc 12 via a motor shaft 151 to drive the grinding disc 12 to rotate. The motor shaft 151 passes through the grinding disc 12 .

[0052] The first heating unit 131 can be disposed on the outer wall, inner wall, or inside the shell 11. As long as the first heating unit 131 is disposed on the shell 11, when the first heating unit 131 starts heating, it will transfer heat to the shell 11, and then transfer heat to the inner wall of the shell 11 through the shell 11. Since the first heating unit 131 is only partially disposed on the shell 11, considering heat loss and the certain thickness of the grinding disc 12, if the projection of the first heating unit 131 on the inner wall of the shell 11 cannot cover the projection of the grinding disc 12 on the inner wall of the shell 11, then after the first heating unit 131 starts heating, the upper and lower ends of the garbage passage may not be heated enough, resulting in incomplete sterilization.

[0053] The food waste treatment equipment in this embodiment also includes a cover plate (not shown in the figure). The cover plate serves as the cover plate of the food waste treatment equipment and is mainly used to cover the grinding chamber to prevent garbage from splashing out during grinding. The shell 11 serves as an integral support structure of the food waste treatment equipment. The grinding chamber is formed inside the shell 11, forming a space for grinding garbage.

[0054] In one embodiment, Figure 2 and Figure 3 As shown, the first heating part 131 is a coil, and the food waste treatment equipment also includes a magnetic flux change generating device 14, which is partially arranged on the grinding disc 12, so that the magnetic flux change generating device 14 and the grinding disc 12 can generate alternating current in the coil to generate heat during the synchronous rotation process.

[0055] The shell 11 is provided with an annular cavity, and the coil is a multi-turn coil. The multi-turn coil is arranged in the annular cavity, which can ensure the safety of the coil during use. The first heating part 131 is installed in the annular cavity. The gas in the annular cavity acts as a medium to quickly transfer heat to the shell 11, and then the generated heat can be transferred to the inner wall of the shell 11 more quickly, which can improve the thermal efficiency. The shape and material of the magnetic flux change generating device 14 are not specifically limited, and it only needs to have strong magnetic conductivity. By changing the magnetic flux entering the coil, alternating current is generated in the coil. When alternating current is generated in the coil, the coil can generate heat, and the heat of the coil can heat the shell 11.

[0056] In one embodiment, Figure 3 and Figure 4 As shown, the magnetic flux change generating device 14 includes a magnetic connector 141 and a magnet 142. The magnetic connector 141 is arranged on the grinding disk 12. The magnet 142 includes a south magnetic pole 1421 and a north magnetic pole 1422. The south magnetic pole 1421 and the north magnetic pole 1422 are arranged in a circumferential direction in sequence. In the process of synchronous rotation of the magnetic connector 141 and the grinding disk 12, the south magnetic pole 1421 and the north magnetic pole 1422 are contacted in sequence.

[0057] The above-mentioned magnetic connector 141 is located on the grinding disc 12, so that the magnetic connector 141 can rotate synchronously with the grinding disc 12. The movement trajectory of the magnetic connector 141 is circular. As long as the magnet 142 is set on the movement trajectory of the magnetic connector 141, the magnetic connector 141 can alternately contact the south magnetic pole 1421 and the north magnetic pole 1422 of the magnet 142.

[0058] The magnet 142 is made of a magnetic conductive material. When the grinding disc 12 rotates, the magnetic connector 141 can alternately contact the south magnetic pole 1421 and the north magnetic pole 1422, thereby changing the magnetic flux entering the coil, so that alternating current can be generated in the coil. Figure 5 As shown, the magnetic connector 141 and the magnet 142 in this embodiment may respectively have arc-shaped contact surfaces, which can increase the contact area between the magnetic connector 141 and the magnet 142.

[0059] Specifically, considering that the frequency of contact between the magnetic connector 141 and the south magnetic pole 1421 and the north magnetic pole 1422 increases, the frequency of change of the magnetic flux entering the coil will also increase. Therefore, the magnet 142 is provided in plurality, and the plurality of south magnetic poles 1421 and north magnetic poles 1422 are arranged alternately in a circumferential direction. By increasing the frequency of contact between the magnetic connector 141 and the south magnetic pole 1421 and the north magnetic pole 1422, the generation of alternating current in the coil can be increased. The magnetic connector 141 alternately contacts the south magnetic pole 1421 and the north magnetic pole 1422, so that the magnetic fields of the south magnetic pole 1421 and the north magnetic pole 1422 are alternately enhanced by the magnetic conductor, and the coil generates an induced current due to the change in magnetic flux.

[0060] In one embodiment, Figure 4 As shown, the magnetic connector 141 is disposed at the bottom of the grinding disc 12 , and the magnet 142 is disposed below the grinding disc 12 .

[0061] It can be understood that, Figure 5 As shown, the movement trajectory of the magnetic connector 141 is a circle, and the magnet 142 is arranged on the circular movement trajectory. The magnet 142 is arranged below the magnetic connector 141, so that the magnetic connector 141 can more conveniently contact the south pole 1421 and the north pole 1422 of the magnet 142 alternately.

[0062] Of course, in other embodiments, Figure 6 As shown, the magnetic connector 141 is disposed on the edge of the grinding disc 12 , and the magnet 142 is disposed on the housing 11 .

[0063] The south magnetic poles 1421 and north magnetic poles 1422 of the magnets 142 can be alternately arranged circumferentially on the housing 11. The magnets 142 can be embedded in the housing 11. When the magnetic connector 141 is rotated to a position opposite the south magnetic pole 1421 and the north magnetic pole 1422, the magnetic connector 141 will contact the south magnetic pole 1421 and the north magnetic pole 1422. By arranging the magnetic connector 141 at the edge of the grinding disc 12 and the magnets 142 on the housing 11, the space used for the magnets 142 and the magnetic connector 141 can be reduced, thereby reducing costs.

[0064] In one embodiment, Figure 7 As shown, the food waste treatment device further includes a controller 18 , which includes a detection module. The detection module is electrically connected to the coil, so that the controller 18 can detect the current of the coil through the detection module.

[0065] The controller 18 can be located at the bottom of the housing 11 or elsewhere. The controller 18 includes a detection module connected to the coil. When alternating current is generated in the coil, the detection module detects the current in the coil. The detected current can be used to determine the rotational speed of the grinding disc 12 and whether the rotational speed of the grinding disc 12 is normal.

[0066] When the driving device drives the grinding disc 12 to rotate at a speed a, there should be an induced current I a When the garbage causes the grinding disc 12 to stall, if the induced current detected by the detection module of the controller 18 is not I a , it indicates that a stall has occurred. At this time, the drive device can be controlled to stop to avoid damage and reduce the service life of the food waste treatment device. Therefore, by detecting the induced current generated by the coil through the detection module of the controller 18, stall can be avoided, thereby increasing its service life.

[0067] When a stall occurs, the controller 18 can control the drive device to stop running or not, depending on the severity of the stall, and control the opening of the switch valve 16. The switch valve 16 is a solenoid valve, and a flow monitor is provided on the solenoid valve to monitor the flow to prevent insufficient water intake due to insufficient water pressure.

[0068] In addition, the controller 18 may further include a control circuit, which may be connected to the motor 15. When the food waste treatment equipment is turned off, the control circuit may control the motor 15 to stop, thereby cutting off the power supply of the motor 15 in time.

[0069] like Figure 3 As shown, in one embodiment, the food waste treatment device further includes a power storage device, which is electrically connected to the coil and connected to the controller 18, so that the controller 18 can control the power storage device to store electrical energy.

[0070] The aforementioned energy storage device may include a capacitor or a battery. The induced current generated by the coil can be stored in the capacitor. When the energy storage device includes a battery, the alternating current generated by the coil needs to be converted into direct current, which can then be stored in the battery.

[0071] The above-mentioned power storage devices can all be realized by existing technologies and will not be described in detail here.

[0072] In one embodiment, the food waste disposal device also includes a warning module electrically connected to the controller 18, the detection module includes a detection circuit, and the warning module is electrically connected to the detection circuit so that when the current detected by the detection circuit does not match the preset current, the warning module sends an alarm signal.

[0073] The controller 18 may include a display screen, and the warning module may include a display screen. When the current detected by the detection circuit does not conform to the preset current, for example, when the detected current is greater than the preset current or less than the preset current, it indicates that the current detected by the detection circuit does not conform to the preset current. At this time, the controller 18 may display in real time on the display screen whether the grinding disc 12 is stalled, so as to promptly alert the user and improve the user experience.

[0074] In addition, the controller 18 can also use a voice device to prompt whether the grinding disc 12 is blocked. Of course, the user can also choose to shield the blockage detection function through the setting.

[0075] In one embodiment, Figure 7 As shown, the shell 11 is provided with a garbage discharge port connected to the grinding chamber, and the garbage discharge port is connected to a garbage discharge pipe 17 . The heating component 13 also includes a second heating part 132 , and the second heating part 132 is provided on the garbage discharge pipe 17 .

[0076] The above-mentioned second heating part 132 can be arranged in a ring on the garbage discharge pipe 17, so that after the second heating part 132 starts heating, it can heat the garbage discharge pipe 17, thereby heating the inner wall of the garbage discharge pipe 17 to reduce the adhesion of garbage to the inner wall of the garbage discharge pipe 17, or sterilize the residual garbage adhering to the inner wall of the garbage discharge pipe 17 to further reduce the growth of bacteria in the garbage discharge pipe 17.

[0077] The second heating portion 132 may be a coil. When the grinding disc 12 rotates, the magnetic connector 141 may alternately contact the south magnetic pole 1421 and the north magnetic pole 1422, thereby changing the magnetic flux entering the second heating portion 132, thereby generating alternating current within the second heating portion 132. The alternating current generated by the second heating portion 132 may also be stored in an energy storage device, thereby increasing the amount of energy stored.

[0078] The second heating unit 132 can also be electrically connected to the detection circuit of the controller 18, thereby making the detection of the occurrence of stall more reliable. For example, if the coil of the first heating unit 131 is damaged, if the AC power generated by the second heating unit 132 is detected to be inconsistent with the current required for the normal speed of the motor 15, then a stall can be determined.

[0079] Furthermore, the heating assembly 13 includes a third heating unit 133, which is disposed on the outer wall of the waste discharge pipe 17 at its outlet. This third heating unit 133 can also be a coil and is also connected to the controller 18 and the power storage device. When the grinding disc 12 rotates, the magnetic connector 141 alternately contacts the south magnetic pole 1421 and the north magnetic pole 1422, thereby varying the magnetic flux entering the third heating unit 133 and generating alternating current within the third heating unit 133.

[0080] The third heating unit 133 is connected to an electricity storage device to increase the storage of electric energy.

[0081] The third heating unit 133 can be electrically connected to the detection circuit of the controller 18, thereby making the detection of the occurrence of stall more reliable. For example, if the coils of the first heating unit 131 and the second heating unit 132 are damaged, if the AC power generated by the third heating unit 133 is detected to be inconsistent with the current required for the normal speed of the motor 15, then a stall can be determined.

[0082] The process of using the heating component 13 of the kitchen waste treatment device of the present invention to provide a garbage blockage reminder is as follows:

[0083] During the grinding operation, the detection circuit of the controller 18 detects the alternating current generated in the coil of the first heating part 131, and then determines whether the alternating current is consistent with the current corresponding to the normal rotation speed of the motor 15. When the alternating current is inconsistent with the current required for the normal rotation speed of the motor 15, it is determined that a stall has occurred. At this time, the controller 18 can control the motor 15 to stop or not, and then the controller 18 controls the switch valve 16 to add water. As the detection circuit determines the consistency between the detected alternating current and the current corresponding to the normal rotation speed of the motor 15, the controller 18 can control the motor 15 to run and drive the grinding disc 12 to rotate to continue the grinding and cleaning operations. The controller 18 can also send a blockage signal to the display screen for display or issue a sound prompt to prompt the user so that the user can take manual measures to clear the blockage when necessary.

[0084] The specific structure of the detection circuit can be realized by existing technology and will not be described in detail here.

[0085] The above-mentioned food waste treatment equipment sets a magnetic connector 141 on the grinding disc 12, so that the grinding disc 12 becomes a magnetic grinding disc. After the magnetic grinding disc starts to rotate, the magnetic grinding disc alternately contacts the N / S poles through the connector, so that the N / S pole magnetic field is alternately enhanced by the magnetic grinding disc, and an induced current is generated in the coil in the grinding chamber structure. The controller 18 detects the induced current to realize the function of detecting the speed of the motor 15 and energy recovery, and the coil is heated due to the induced current to realize the sterilization function.

[0086] like Figure 8 As shown, the control device includes a controller 18, a motor 15, a switch valve 16 and a heating component 13. The controller 18 can control the opening or closing of the motor 15. The controller 18 can also control the opening, closing and flow regulation of the switch valve, and the controller 18 can control the heating component 13 to connect to the detection module or cut off the electrical connection between the heating component 13 and the detection module.

[0087] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
