Description

TECHNICAL FIELD

[0001] The utility model belongs to garbage disposal technical field, concretely relates to a kitchen garbage disposal. BACKGROUND

[0002] The existing kitchen garbage disposal generally includes a casing with a feed inlet and a discharge outlet, a crushing element arranged in the casing, and a driving mechanism for driving the crushing element to work, and the crushing element can crush the kitchen garbage entering from the feed inlet under the driving of the driving mechanism.

[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 connected 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 arranged below the sink, the garbage disposal 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] After the kitchen garbage disposal finishes processing the garbage, part of the kitchen garbage residue will adhere to the wall surface of the crushing cavity, and will mildew, stink and breed bacteria after a long time. At present, there are two ways of water inlet for kitchen garbage disposals on the market, one is to manually open the water faucet to inlet water, which cannot clean the inner wall of the cavity; the second is automatic water inlet, although the automatic water inlet can solve the trouble of opening the water faucet when the user uses the garbage disposal, but the cleaning effect of the inner wall of the crushing cavity during automatic water inlet needs to be further improved.

[0006] At the same time, the electric control assembly in the kitchen garbage disposal on the market will affect the service life due to temperature rise when working. Generally, the electric control assembly of the kitchen garbage disposal 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.

[0007] To this end, a heat dissipation module is arranged below the electric control assembly to dissipate heat through natural convection with air, but this method requires a large heat sink to match, increasing the cost. Meanwhile, the arrangement of the existing heat dissipation module occupies additional height space in the machine, resulting in a large machine size and inconvenience for installation. Utility model content

[0008] The first technical problem to be solved by the utility model is to provide a kitchen waste disposer capable of improving the cleaning effect of the inside of the crushing chamber during the water inlet process.

[0009] The second technical problem to be solved by the utility model is to provide a kitchen waste disposer capable of improving the heat dissipation effect of the electric control assembly.

[0010] The second technical problem to be solved by the utility model is to provide a compact kitchen waste disposer.

[0011] The technical scheme adopted by the utility model to solve the above first technical problem is as follows:

[0012] A shell has a crushing chamber and an annular chamber arranged along the outer periphery of the side wall of the crushing chamber, the annular chamber is provided with a water inlet hole for the water source from outside to enter, the side wall of the crushing chamber is provided with a water outlet hole along the circumference to connect the crushing chamber and the annular chamber, the upper part of the crushing chamber is provided with a feeding port, and the lower part of the crushing chamber is provided with a discharging port.

[0013] An annular heating element is arranged in the annular chamber along the circumference to heat the water source in the annular chamber, and at least part of the surface of the heating element has a gap with the inner wall surface of the annular chamber to maintain the communication state of the water inlet hole and the water outlet hole of the annular chamber.

[0014] A crushing element is arranged in the crushing chamber and can work under the drive of the driving mechanism to crush the kitchen waste entering from the feeding port.

[0015] The annular chamber in the utility model can play the role of a water storage chamber, the water source enters the annular chamber through the water inlet hole and is heated to increase the temperature under the action of the heating element, and then is sprayed into the crushing chamber from the water outlet hole. Since the water outlet hole is arranged along the circumference of the side wall of the crushing chamber, the water flow sprayed from the water outlet hole can flush the inner wall surface of the crushing chamber in multiple directions and a large range, and the heated water flow is beneficial to the cleaning of the inside of the crushing chamber during the garbage disposal process and the discharge of grease and residues. Meanwhile, the cooperation of the annular chamber and the heating element in the utility model has the following technical effects:

[0016] 1. Ensure that the water source in the annular chamber can be heated; 2. The flow rate of the water source entering the annular chamber is relatively slow, so that the water source can be effectively heated.

[0017] Preferably, the kitchen garbage disposer further comprises:

[0018] An electric control assembly electrically connected with the driving mechanism;

[0019] A heat-conducting member acting between the electric control assembly and the heating member for transferring heat generated by the electric control assembly to the heating member.

[0020] Thus, the temperature rise of the electric control assembly during operation can be effectively alleviated, the service life is improved, and the energy saving advantage is achieved.

[0021] In addition, the heating member can also be an electric heating rod which generates heat after being powered on.

[0022] Preferably, the heating member is a heat exchange pipe which is hollow inside and has a heat-conducting pipe wall, the pipe wall of the heat exchange pipe is provided with a flow-through opening for the heat exchange medium to enter and exit, and the edge of the flow-through opening extends to the outside of the annular chamber.

[0023] Further, the electric control assembly is located on the lower side of the crushing chamber and the annular chamber.

[0024] The heat-conducting member comprises a heat dissipation chamber which is arranged above the electric control assembly, the bottom wall of the heat dissipation chamber is a heat-conducting wall and is in contact with the electric control assembly, the through hole at the top of the heat dissipation chamber is communicated with the flow-through opening of the heating member through a connecting pipe, and the heat dissipation chamber contains the above-mentioned heat exchange medium which can change phase between gas and liquid with the change of temperature.

[0025] In this way, the heat generated by the electric control assembly during the operation of the kitchen garbage disposer is transferred to the bottom wall of the heat dissipation chamber in the form of heat conduction, and then is transferred to the heating member in the form of phase change heat exchange, and the water flowing outside the heating member can take away this part of heat, so that the temperature rise of the electric control assembly during operation can be effectively alleviated, and the service life is improved.

[0026] The working principle of phase change heat exchange is that the heat exchange medium (such as refrigerant) is in a mixed state of gas and liquid, and because the density of gaseous refrigerant is different from that of liquid refrigerant, the gaseous refrigerant generally flows upward into the heating pipe, and the liquid refrigerant generally flows downward into the heat dissipation chamber. At this time, the gaseous refrigerant in the heating pipe will liquefy into liquid refrigerant and deposit downward in the heat dissipation chamber under low temperature (the water flowing outside the heating member 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.

[0027] The above connecting pipe and heating pipe can be an existing heat pipe. The heat pipe mainly uses the gas-liquid two-phase of a working medium to transfer heat from the electric control assembly to the corresponding position and dissipate heat through heat power, gravity and capillary action.

[0028] Preferably, the bottom wall of the crushing chamber and the top wall of the heat dissipation chamber are both heat-conducting walls and contact each other. In this way, the heat generated by the electric control assembly during the operation of the kitchen waste processor can be transferred to the bottom wall of the heat dissipation chamber in the form of heat conduction, and then transferred to the bottom wall of the crushing chamber in the form of phase change heat exchange of the heat exchange medium. The crushed kitchen waste flowing towards the discharge port in the crushing chamber can take away part of the heat, thereby effectively alleviating the temperature rise of the electric control assembly during operation and improving the service life.

[0029] Preferably, the discharge port is located on the right side of the crushing chamber, and the heat dissipation 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.

[0030] Preferably, the electric control assembly and the driving mechanism are arranged side by side in the horizontal direction. 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 is conducive to its contact with the bottom wall of the crushing chamber.

[0031] In the above schemes, preferably, the flow area on the cross section of the annular chamber gradually increases from bottom to top, the heating element is arranged on the upper side of the annular chamber, and the water outlet holes are located above the water inlet holes. In this way, the residence (heat exchange) time of the water flow in the annular chamber can be increased.

[0032] Preferably, the water outlet holes are at least two and are arranged in the side wall of the crushing chamber in a circumferential direction at intervals, and each water outlet hole is inclined upward. The water flow jetted from each water outlet hole flows upward obliquely, which can wash the inner wall surface of the crushing chamber above the annular chamber, and then flows downward under the action of its own gravity to clean the inner wall surface of other positions of the crushing chamber.

[0033] Preferably, the extension direction of the water outlet holes is arranged at an angle with the radial direction of the corresponding side wall of the crushing chamber, so that the direction of each water outlet hole is arranged in the circumferential direction as a whole in a clockwise or counterclockwise rotation direction. In this way, the water flow jetted from each water outlet hole not only flows upward obliquely, but also flows along the rotation direction to form an annular flow, avoiding the mutual impact of the water flows and improving the cleaning effect.

[0034] Compared with the prior art, the annular chamber in the utility model can play the role of the water storage cavity, the water source enters the annular chamber through the water inlet hole, and is heated and temperature is increased under the action of the heating piece, and then is sprayed into the smashing chamber from the water outlet hole, since the water outlet hole is arranged along the circumference of the side wall of the smashing chamber, the water flow sprayed from the water outlet hole can flush the inner wall surface of the smashing chamber in multiple directions and a large range, and the heated water flow is beneficial to the cleaning of the inside of the smashing chamber in the garbage treatment process, and is beneficial to the discharge of grease and residues. Meanwhile, the cooperation of the annular chamber and the heating piece in the utility model has the following technical effects: 1. the water source in each part of the circumference of the annular chamber can be heated; 2. the flow speed of the water source entering the annular chamber is relatively slow, so that the water source can be effectively heated.

[0042] The utility model will be described further in detail below in combination with the embodiment of the drawings.

[0043] As Figures 1 to 7 shown, it is a preferred embodiment of the kitchen garbage disposer of the utility model, and the kitchen garbage disposer comprises a machine shell 1, a smashing piece 2, a driving mechanism 3, a flow guide cylinder 4, a heating piece 5, an electric control assembly 6 and a heat conducting piece 7.

[0044] The machine shell 1 has a vertically arranged ring wall, the bottom of the ring wall is closed through a bottom wall, the top is open as a feeding port 10a, and the lower part of the ring wall is provided with a discharging port 10b, and the upper part of the ring wall is provided with a water inlet hole 11a.

[0045] The above-mentioned draft tube 4 is vertically arranged in the inner periphery of the upper portion of the ring wall of the casing 1, and has a side peripheral wall 40 which is inclined toward the center from bottom to top. The upper end and the lower end of the side peripheral wall 40 are connected to the corresponding ring wall (the connection includes but is not limited to welding, screw connection, buckle connection and the like), so that the side peripheral wall 40 and the ring wall form a ring-shaped chamber 11 with the above-mentioned water inlet hole 11a therebetween. The flow area of the ring-shaped chamber 11 in the cross section gradually increases from bottom to top. The side peripheral wall 40 and the ring wall between the upper and lower portions of the side peripheral wall jointly form a crushing chamber 10. Meanwhile, the upper portion of the side peripheral wall 40 is provided with three water outlet holes 10c which are equidistantly arranged in the circumferential direction, so as to communicate the crushing chamber 10 and the ring-shaped chamber 11. The water outlet holes 10c are located above the water inlet hole 11a, and each water outlet hole 10c is inclined upward, and the upward inclination angle b of the water outlet hole 10c with respect to the horizontal plane is 50-60° (the inclination angle b can be any value between 50-60°, such as 50°, 55°, 60° and the like). For details, see Figure 7 The inclination angle b can ensure that the water flow washes the inner side of the feed inlet 10a at the top of the crushing chamber. Meanwhile, as shown in Figure 5 , the extension direction of the water outlet hole 10c is arranged at an included angle a with respect to the radial direction of the corresponding side peripheral wall 40, so that the direction of each water outlet hole 10c is arranged in the circumferential direction as a whole in the clockwise or counterclockwise rotation direction, and the included angle a is 30-40° (the included angle a can be any value between 30-40°, such as 30°, 35°, 40° and the like). The included angle a can ensure that the water flow flows along the side wall surface of the crushing chamber to form a circular flow. Meanwhile, the water outlet hole 10c of the present embodiment is a parallelogram, the short side of the parallelogram extends along the circumferential direction of the side peripheral wall 40, and the long side extends along the longitudinal direction of the side peripheral wall 40. Along the water flow direction, the flow area of the water outlet hole 10c in the cross section gradually decreases. Specifically, the size of the water inlet end of the water outlet hole 10c is 10x5mm, the size of the water outlet end is 5x2.5mm, and the sum of the water outlet end areas of the three water outlet holes 10c is 37.5mm 2 , and the water inlet area of the water inlet hole 11a is 111.3mm 2 , which is exactly 3 times the sum of the water outlet end areas of the three water outlet holes 10c (of course, the water inlet area of the water inlet hole 11a can be increased or the water outlet end area of the water outlet hole 10c can be reduced in the present embodiment, so that the water inlet area of the water inlet hole 11a is 3-4 times the sum of the water outlet areas of the water outlet holes 10c). In this way, the water in the ring-shaped chamber 11 is pressurized, so that the water flow is obliquely sprayed upward, and will not sink under the action of gravity.

[0046] The crushing member 2 is arranged in the crushing chamber 10, below the water outlet 10c and above the discharge port 10b, and can crush the kitchen garbage entering from the feeding port 10a under the driving of the driving mechanism 3. In the embodiment, the crushing member 2 is a conventional grinding disc, and the driving mechanism 3 is a conventional motor. The rotating shaft of the motor extends upward and is connected to the center of the grinding disc to drive the rotation of the grinding disc. The specific structure of the grinding disc and the principle of crushing the kitchen garbage are the same as those of the prior art, and thus will not be described here.

[0047] As shown in Figure 2 , the electric control assembly 6 is a conventional technology, which is arranged below the crushing chamber 10 and horizontally beside the driving mechanism 3, and is electrically connected with the driving mechanism 3.

[0048] As shown in Figures 2 to 4 , the annular heating member 5 is arranged in the upper space of the annular chamber 11 in the circumferential direction to heat the water source in the annular chamber 11. The inner annular surface of the heating member 5 and the side peripheral wall 40 of the flow guide cylinder 4 have an annular gap to maintain the communication state between the water inlet 11a of the annular chamber 11 and the water outlet 10c. The outer annular surface of the heating member 5 is in close contact with the annular wall of the casing 1.

[0049] The heat-conducting member 7 acts between the electric control assembly 6 and the heating member 5 to transfer the heat generated by the electric control assembly 6 to the heating member 5. In the embodiment, the heating member 5 is a heat exchange pipe with a hollow interior and a pipe wall capable of conducting heat. The pipe wall of the heat exchange pipe is provided with flow-through openings for the heat exchange medium to enter and exit. The heat-conducting member 7 includes a heat dissipation chamber 70 arranged above the electric control assembly 6. The bottom wall of the heat dissipation chamber 70 is a heat-conducting wall in contact with the electric control assembly 6. The top wall of the heat dissipation chamber 70 is a heat-conducting wall in contact with the bottom wall of the crushing chamber 10. The through hole at the top of the heat dissipation chamber 70 is communicated with the flow-through openings of the heating member 5 through a connecting pipe 71. The heat dissipation chamber 70 contains the heat exchange medium capable of changing between gas and liquid with the change of temperature. The heating member 5 and the connecting pipe 71 can adopt a conventional heat pipe. The working principle of the heat pipe is that the heat is transferred from the hot end of the electric control assembly 6 to the corresponding position and dissipated by using the gas-liquid two-phase of the working medium through heat power, gravity and capillary action.

[0050] Meanwhile, in the embodiment, the discharge port 10b is located at the right side of the crushing chamber 10, and the heat dissipation chamber 7 is arranged at the left side of the bottom wall of the crushing chamber 10.

[0051] The heat generated by the electric control assembly 6 during the operation of the kitchen garbage disposer is transferred to the bottom wall of the heat dissipation chamber 70 in the form of heat conduction, and then is transferred to the heating member 5 and the bottom wall of the crushing chamber 10 in the form of heat exchange by the phase change of the heat exchange medium. The water flowing outside the heating member and the kitchen garbage and water flowing to the discharge port in the crushing chamber can take away this part of heat, so as to effectively alleviate the temperature rise of the electric control assembly 6 during operation and improve the service life.
