[0003] Specifically, the Chinese utility model patent "kitchen garbage disposal" with the patent number 202221965311.8 and the authorized announcement number CN218292145U includes a casing and a grinding cover, a grinding disc is installed inside the grinding cover, the grinding cover includes an upper grinding cover and a lower grinding cover, a feeding port is opened at the top of the upper grinding cover, a discharge port is opened on the upper part of the lower grinding cover, an annular wall is installed on the inner circumferential wall of the lower side of the upper grinding cover, the annular wall is arranged above the grinding disc, an annular cavity is formed between the annular wall and the upper grinding cover, a water inlet is opened on the outer circumferential wall of the upper grinding cover and is in communication with the annular cavity, a water outlet hole is opened on the inner wall of the annular cavity, and an annular cutter capable of rotating under the action of water pressure is installed in the annular cavity.

[0004] For example, the Chinese utility model patent "kitchen garbage disposal system" with the patent number 202321652436.X and the authorized announcement number CN220538788U includes a sink and a garbage disposal device arranged below the sink, the garbage disposal device includes a grinding cavity and a grinding disc arranged in the grinding cavity, the grinding cavity has a discharge port, the discharge port is arranged below the grinding disc, a step structure is formed at the bottom of the sink, a main feeding port is opened at the top of the step structure, a feeding cover is installed on the main feeding port, and the top of the grinding cavity is installed on the main feeding port.

[0005] When the kitchen garbage disposal device on the market works, the electric control assembly in it will be affected by temperature rise, thereby affecting the service life. Generally, the electric control assembly of the kitchen garbage disposal device is located at the bottom or side of the machine, and when the electric control assembly is repaired, the machine often needs to be taken off from the sink and then disassembled for repair, which is relatively inconvenient to operate.

[0006] Therefore, a heat dissipation module is arranged below the electric control assembly, and heat dissipation is achieved through natural convection with air, but this method needs to match a larger heat sink, thereby increasing the cost. At the same time, the arrangement of the existing heat dissipation module will additionally occupy the height space in the machine, thereby causing the machine to be relatively large in size and inconvenient to install. UTILITY MODEL CONTENTS

[0007] The first technical problem to be solved by the utility model is to provide a kitchen garbage disposal device capable of improving the heat dissipation effect of the electric control assembly according to the status of the prior art.

[0008] The second technical problem to be solved by the utility model is to provide a compact kitchen waste processor.

[0009] The utility model solves the above-mentioned first technical problem adopts the technical scheme of a kitchen waste processor, comprising:

[0010] The shell has a crushing chamber inside, the upper part of the crushing chamber has a feeding port, and the lower part of the crushing chamber has a discharging port;

[0011] The crushing part is arranged in the crushing chamber and can work under the drive of the drive mechanism to crush the kitchen waste entering from the feeding port;

[0012] The electric control assembly is located below the crushing chamber and is electrically connected with the drive mechanism;

[0013] It is characterized in that:

[0014] The bottom wall of the crushing chamber is a heat-conducting wall and forms a closed heat dissipation chamber with the upper side of the electric control assembly, and the heat dissipation chamber has a heat exchange medium that can change phase between gas and liquid with temperature change.

[0015] In this way, the heat generated by the electric control assembly during the operation of the kitchen waste processor is transmitted to the heat dissipation chamber in the form of heat conduction, and then transmitted to the bottom wall of the crushing chamber in the form of phase change heat exchange of the heat exchange medium, and the crushed kitchen waste flowing to the discharging port in the crushing chamber can take away part of the heat, thereby effectively relieving the temperature rise of the electric control assembly during operation and improving the service life.

[0016] The working principle of phase change heat exchange is that the heat exchange medium (such as refrigerant) in the heat dissipation chamber is in a gas-liquid mixed state, and because the density of gaseous refrigerant is different from that of liquid refrigerant, the gaseous refrigerant is located in the upper part of the internal space of the heat dissipation chamber, and the liquid refrigerant is located in the lower part of the internal space of the heat dissipation chamber, at this time, the gaseous refrigerant in the upper part of the internal space of the heat dissipation chamber will liquefy into liquid refrigerant and deposit downward in the lower part of the internal space of the heat dissipation chamber under low temperature (the crushed kitchen waste flowing to the discharging port in the crushing chamber can take away heat in time), and the liquid refrigerant will vaporize into gaseous refrigerant and take away the heat around under high temperature (heat generated by the electric control assembly during operation), thereby achieving the cooling of the electric control assembly.

[0017] Preferably, the heat dissipation chamber has a heat-conducting bottom wall, a side peripheral wall extending upward from the periphery of the heat-conducting bottom wall, the upper edge of the side peripheral wall is supported on the lower side of the bottom wall of the crushing chamber, and the heat-conducting bottom wall, the side peripheral wall and the bottom wall of the crushing chamber jointly form the heat dissipation chamber;

[0018] The upper side of the electric control assembly is attached to the lower side of the heat-conducting bottom wall.

[0019] Of course, the heat-dissipating chamber can also be formed directly by the side wall, the bottom wall of the crushing chamber and the upper surface of the electric control assembly.

[0020] To further solve the second technical problem, preferably, the electric control assembly is arranged horizontally side by side with the driving mechanism. In this way, the height of the kitchen waste processor itself can be reduced, and the electric control assembly arranged side by side with the driving mechanism facilitates its contact with the bottom wall of the crushing chamber.

[0021] Preferably, the discharge port is located on the right side of the crushing chamber, and the heat-dissipating chamber is arranged corresponding to the left side of the bottom wall of the crushing chamber. In this way, the space below the left side of the crushing chamber can be effectively utilized, and the heat exchange effect can be ensured.

[0022] In the above-mentioned solutions, preferably, the side wall of the crushing chamber is provided with a water inlet hole for the external water source to enter;

[0023] A flow guide cylinder is further included, which is arranged in the crushing chamber above the crushing element. The flow guide cylinder has a side ring wall which is inclined from bottom to top to the center. The upper end and the lower end of the side ring wall are connected to the corresponding side wall of the crushing chamber, so that the side ring wall and the side wall of the crushing chamber form a ring cavity with the water inlet hole. The upper part of the side ring wall is provided with at least two water outlet holes in the circumferential direction. Each water outlet hole is inclined upward and located above the water inlet hole.

[0024] Of course, the flow guide cylinder can not be additionally arranged, and the water source can directly enter the crushing chamber from the water inlet hole. The flowing water source can further take away the heat of the bottom wall of the crushing chamber. The water source can also enter the crushing chamber from the feeding port together with the kitchen waste.

[0025] The ring cavity formed between the flow guide cylinder and the side wall of the crushing chamber in the utility model plays the role of a water storage cavity. The water source entering from the water inlet hole flows into the ring cavity and flows upward along the side wall of the flow guide cylinder and is sprayed upward from each water outlet hole. The sprayed water flow can flush the inner wall surface of the crushing chamber above the flow guide cylinder and then flow downward under the action of its own gravity to clean the inner wall surface of other positions of the crushing chamber. In addition, the cooperation of the inclined side wall, the water outlet hole located in the upper part of the side wall and inclined upward, and the water inlet hole located below the water outlet hole in the utility model is conducive to the upward flow of the water flow sprayed from the water outlet hole. At the same time, the side wall which is inclined from bottom to top to the center in the utility model is conducive to the passing of the kitchen waste.

[0026] Preferably, the water outlet hole is in the shape of a parallelogram.

[0027] Preferably, the cross-sectional area of the water outlet hole gradually decreases along the water flow direction, so that the water flow is accelerated when being ejected from the water outlet hole.

[0028] Preferably, the water inlet area of the water inlet hole is 3-4 times the sum of the water outlet areas of the water outlet holes, so that the water in the annular cavity is pressurized, further ensuring that the water flow is ejected obliquely upward from the water outlet holes.

[0029] Further, the extension direction of the water outlet hole is arranged at an angle with the radial direction of the corresponding side ring wall, so that the water outlet holes are arranged in a whole clockwise or counterclockwise rotation direction in the circumferential direction, so that the water flow ejected from the water outlet holes not only flows obliquely upward, but also flows along the rotation direction to form an annular flow, avoiding mutual impact of the water flows, and improving the cleaning effect.

[0030] Further, the water outlet hole has three and is arranged equidistantly in the circumferential direction.

[0031] Compared with the prior art, the heat generated by the electric control assembly during the operation of the kitchen garbage disposer is transferred to the heat dissipation chamber in the form of heat conduction, and then is transferred to the bottom wall of the crushing chamber in the form of heat exchange medium phase change, so that the kitchen garbage after crushing flowing to the discharge port can take away the heat, thereby effectively relieving the temperature rise of the electric control assembly during operation, and prolonging the service life.
