[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 disposer arranged below the sink, the garbage disposer 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] The existing kitchen garbage disposer generally uses the water inlet mode of opening the water faucet of the sink, cooperates with the crushing and grinding of the crushing piece, plays the effect of treating and discharging the garbage, and some kitchen garbage disposers realize automatic water inlet in the cavity through a valve body, which is more convenient and does not need manual operation, and the water is automatically turned off after work, which saves time and effort.

[0006] The kitchen garbage disposer that realizes automatic water inlet in the cavity through the valve body, after treating the kitchen garbage, some kitchen garbage residues will be attached to the inner wall surface of the grinding cavity or enter the water inlet hole. And the water flow entering the cavity from the water inlet hole generally flows downward under the action of its own gravity, and the cavity wall surface, especially the cavity wall surface above the water inlet hole, cannot be cleaned. UTILITY MODEL CONTENTS

[0007] The first technical problem to be solved by this utility model is to provide a food waste disposer that can achieve self-cleaning of the cavity wall, especially the cavity wall above the water inlet, in light of the current state of the technology.

[0008] The second technical problem to be solved by this utility model is to provide a food waste disposer that can prevent food waste residue from clogging the water inlet.

[0009] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a kitchen waste disposer, comprising:

[0010] The machine casing has a grinding chamber inside, with a feed inlet at the top and a discharge outlet at the bottom, and the side wall of the grinding chamber is provided with a water inlet for external water to enter.

[0011] A shredder is disposed inside the shredding chamber and can work under the drive of the drive mechanism to shred kitchen waste entering from the feed inlet;

[0012] Its characteristic is that it also includes:

[0013] The nozzle is disposed in the water inlet hole in such a way that it can move inward and outward along the extension direction of the water inlet hole, and the inner end face of the nozzle faces the crushing chamber. The edge of the inner end face is adjacent to or fits against the inner side of the water inlet hole. At least the upper part of the outer end face of the nozzle is inclined inward from bottom to top to form a slope. The nozzle is arranged to be able to move inward when an external water source applies a force to the slope, so that a first channel for water source to pass through is formed between the slope and the upper edge of the corresponding water inlet hole.

[0014] An elastic element acts on the nozzle to ensure that the nozzle always tends to move outward and close the water inlet.

[0015] When in use, water enters the inlet and impacts the inclined surface of the nozzle, causing it to move inward. A first channel is formed between the inclined surface of the nozzle and the upper edge of the corresponding inlet. Water then flows upward along the inclined surface through this second channel to flush the wall of the pulverizing chamber above the inlet. When the water is turned off, the nozzle moves outward and resets under the action of an elastic element to prevent food residue from entering the inlet and the first channel.

[0016] Preferably, the upper edge of the inclined surface extends to the inner end face of the nozzle and engages with the upper edge of the inner end face.

[0017] The aforementioned elastic element can be a spring, a spring, etc. Preferably, the elastic element is an inwardly and outwardly extending spring, which is sleeved on the outer periphery of the nozzle. The inner end of the spring acts on the flange on the outer peripheral surface of the nozzle, and the outer end of the spring acts on the step on the inner side of the water inlet. The flange, the step, and the corresponding inner side of the water inlet and the outer peripheral surface of the nozzle form an annular cavity for accommodating the spring. The fluid in the annular cavity is compressed as the nozzle moves inward. The fluid can be a gas such as air in the annular cavity, or a liquid such as water.

[0018] To further address the second technical problem mentioned above, preferably, the nozzle contains:

[0019] A second channel extending vertically, the upper end of the second channel opening into the upper side of the inclined surface, and the lower end of the second channel communicating with the annular chamber;

[0020] The pressure relief return chamber is located beside the second channel, and the inlet of the pressure relief return chamber is located on the side wall of the lower part of the second channel. The outlet of the pressure relief return chamber is connected to the annular chamber, and a one-way valve for closing the outlet is provided at the outlet. When the pressure in the pressure relief return chamber is greater than the pressure in the annular chamber, the one-way valve opens.

[0021] A push rod is inserted into the second channel. The lower end of the push rod is located below the inlet of the pressure relief return chamber, and the upper end of the push rod is located inside the second channel. The push rod is arranged so that it can move upward under the action of the compressed fluid in the annular chamber, so that the upper end of the push rod extends out relative to the inclined surface. At this time, the lower end of the push rod is located above the inlet of the pressure relief return chamber.

[0022] Thus, as the nozzle moves inward, the push rod moves upward under the action of the compressed fluid, extending relative to the inclined surface, thereby pushing aside the food residue above and preventing it from clogging the first channel. After the push rod moves upward under the action of the compressed fluid, its lower end is positioned above the inlet of the pressure relief return chamber, protruding from the inlet. The compressed fluid can then enter the pressure relief return chamber through the inlet to relieve pressure. After pressure relief, the push rod falls back into the second channel under its own gravity (i.e., when the nozzle is maintained in the inward-open position under the action of the water source, the push rod is in the state of falling back into the second channel, without affecting the water output of the first channel). After the water is turned off, the nozzle moves outward, the pressure in the annular chamber decreases, the one-way valve automatically opens, and the fluid in the pressure relief return chamber flows out from the outlet and back into the annular chamber.

[0023] Preferably, the nozzle is further provided with a third channel extending outward from the lower end of the second channel, the outer end of the third channel is connected to the annular chamber, and the outlet of the pressure relief and return chamber is located on the side wall of the third channel.

[0024] Furthermore, the upper end face of the push rod is an inclined end face that matches the inclined plane. After the push rod falls back into the second channel, the upper end face of the push rod and the inclined plane are on the same plane, which does not affect the water flow from being sprayed upwards along the inclined plane.

[0025] In the above solutions, to improve the cleaning effect, preferably, the sidewall of the pulverizing chamber has a first side peripheral wall and a second side peripheral wall located inside the first side peripheral wall. The upper and lower ends of the second side peripheral wall are joined with the corresponding first side peripheral wall so that an annular water storage cavity is formed between the first side peripheral wall and the second side peripheral wall. The second side peripheral wall is provided with at least two water inlets spaced apart along the circumference. Each water inlet is provided with the above-mentioned nozzle and elastic element. The first side peripheral wall is provided with an inlet for external water to enter the water storage cavity.

[0026] The design of at least two water inlets can improve the cleaning range. Water enters through the inlet and fills the water storage chamber. As the water storage chamber fills with water, the water pressure increases. When the water pressure increases to a certain value, it can overcome the elastic force of the elastic element and push the nozzle to move inward, and water is sprayed out from the first channel.

[0027] Preferably, the extension direction of the water inlet holes is arranged at an angle to the radial direction of the corresponding second side peripheral wall, so that each water inlet hole is arranged in a clockwise or counterclockwise spiral direction. This allows the sprayed water to flow along the wall surface and form a swirling flow, improving the cleaning effect.

[0028] Furthermore, the second side peripheral wall slopes from bottom to top towards the center, the water inlet is located on the upper part of the second side peripheral wall, and the water outlet is located below the water inlet.

[0029] Furthermore, the feed inlet is located at the top of the crushing chamber, and the water inlet is located below the feed inlet and above the crushed parts. The water jet from the water inlet can clean the inner wall surface of the feed inlet.

[0030] Compared with existing technologies, the advantages of this invention are as follows: By configuring a nozzle and an elastic element, when in use, water entering the inlet hole impacts the inclined surface of the nozzle, causing the nozzle to move inward. A first channel is formed between the inclined surface of the nozzle and the upper edge of the corresponding inlet hole, allowing water to spray out from the second channel at an upward angle along the inclined surface to rinse the wall of the pulverizing chamber above the inlet hole. After the water is turned off, the nozzle moves outward and resets under the action of the elastic element to prevent food residue from entering the inlet hole and the first channel.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] like Figures 1-7 As shown, this is a preferred embodiment of a food waste disposer of the present invention. The food waste disposer includes a shell 1, a pulverizing component 2, a driving mechanism 3, a nozzle 4, and an elastic component 5.

[0040] The housing 1 has a grinding chamber 10 inside. The top of the grinding chamber 10 has a feed inlet 10a, the lower side wall of the grinding chamber 10 has a discharge outlet 10b, and the upper side wall of the grinding chamber 10 has a water inlet 10c for external water to enter. In this embodiment, the upper side wall of the grinding chamber 10 has a first side peripheral wall 12 and a second side peripheral wall 13 located inside the first side peripheral wall 12. The upper and lower ends of the second side peripheral wall 13 are joined with the corresponding first side peripheral wall 12 to form an annular water storage cavity 120 between the first side peripheral wall 12 and the second side peripheral wall 13. The second side peripheral wall 13 is inclined from bottom to top towards the center. At least two of the above-mentioned water inlets 10c are spaced apart along the circumference on the upper part of the second side peripheral wall 13 (in this embodiment, there are 5 water inlets 10c, which are arranged at equal intervals along the circumference). The extension direction of the water inlet 10c is arranged at an angle to the radial direction of the corresponding second side peripheral wall 13, so that each water inlet 10c is arranged in a clockwise or counterclockwise spiral direction. Please refer to [link to relevant documentation] for details. Figure 4 The first side wall 12 has an inlet 121 for external water to enter the water storage chamber 120, and the inlet 121 is located below the inlet hole 10c. The inlet 121 is connected to a water pipe 122, and a solenoid valve is provided on the water pipe 122 to control the water flow rate in the water pipe 122.

[0041] There are five nozzles 4, each located within its corresponding water inlet 10c. The inner end face 41 of each nozzle 4 faces the pulverizing chamber 10. The upper part of the outer end face of each nozzle 4 slopes inward from bottom to top to form an inclined surface 42. The upper edge of the inclined surface 42 extends to the inner end face 41 of the nozzle 4 and engages with the upper edge of the inner end face 41. Each nozzle 4 can move inward or outward along the extending direction of its respective water inlet 10c to a closed or open position. Figures 2-4 As shown, in the closed position, the edge of the inner end face 41 of the nozzle 4 is adjacent to or abuts the inner surface of the water inlet 10c to close the water inlet 10c; and the nozzle 4 is arranged so that it can move inward to the open position when an external water source applies a force to the inclined surface 42, thereby forming a first channel 420 for water supply between the inclined surface 42 and the upper edge of the corresponding water inlet 10c. At this time, the water inlet 10c is connected to the pulverizing chamber 10 through the first channel 420. For details, please refer to [link to relevant documentation]. Figures 5-7 In this embodiment, the upper edge of the water inlet 10c is chamfered to facilitate the water flow from the first channel 420 being sprayed upwards at an angle.

[0042] There are also five elastic elements 5, each acting on its corresponding nozzle 4, so that the corresponding nozzle 4 always tends to move outward to the closed position. In this embodiment, as... Figure 3 , 6 As shown, the elastic element 5 is an inner and outer extending spring, which is sleeved on the outer periphery of the nozzle 4. The inner end of the spring acts on the flange 43 on the outer peripheral surface of the nozzle 4, and the outer end of the spring acts on the step 11 on the inner side of the water inlet hole 10c. The flange 43, the step 11, and the inner side of the corresponding water inlet hole 10c and the outer peripheral surface of the nozzle 4 form an annular cavity 100 for accommodating the spring. The fluid in the annular cavity 100 is compressed as the nozzle 4 moves inward.

[0043] At the same time, such as Figure 3 , 6As shown, to prevent food waste from clogging the first channel, this embodiment provides a second channel 44, a third channel 47, and a pressure relief and return chamber 45 in each nozzle 4. The second channel 44 extends vertically, and its upper end opens onto the upper side of the inclined surface 42. The third channel 47 extends outward from the lower end of the second channel 44, and its outer end communicates with the corresponding annular chamber 100. The pressure relief and return chamber 45 is located beside the second channel 44 and above the third channel 47. The inlet 451 of the pressure relief and return chamber 45 is located on the lower side wall of the second channel 44, and the outlet 452 of the pressure relief and return chamber 45 is located on the top wall of the third channel 47. A one-way valve for closing the outlet 452 is provided at the outlet 452. When the pressure in the pressure relief and return chamber 45 is greater than the pressure in the annular chamber 100, the one-way valve opens. In this embodiment, the one-way valve is a conventional valve plate structure, which is rotatably connected to the outlet 452. Meanwhile, a push rod 46 is inserted into the second channel 44. The lower end of the push rod 46 is located below the inlet 451 of the pressure relief and return chamber 45, and the upper end of the push rod 46 is an inclined end face that matches the inclined surface 42 and is located in the second channel 44 and arranged coplanarly with the inclined surface 42. The push rod 46 is arranged so that it can move upward under the action of the compressed fluid in the annular chamber 100, so that the upper end of the push rod 46 extends relative to the inclined surface 42. At this time, the lower end of the push rod 46 is located above the inlet 451 of the pressure relief and return chamber 45. Thus, as the nozzle 4 moves inward, the push rod 46 moves upward under the action of the compressed fluid and extends relative to the inclined surface 42, thereby pushing and puncturing the kitchen waste residue above, preventing the residue from clogging the first channel 420. Furthermore, after the push rod 46 moves upward under the action of the compressed fluid, the lower end of the push rod 46 is positioned above the inlet 451 of the pressure relief return chamber 45 and protrudes from the inlet 451. The compressed fluid can enter the pressure relief return chamber 45 through the inlet 451 to achieve pressure relief. After pressure relief, the push rod 46 falls back into the second channel 44 under its own gravity (that is, when the nozzle 4 is maintained in the inward open position under the action of the water source, the push rod 46 is in the state of falling back into the second channel 44, which does not affect the water output of the first channel 420). After the water is turned off, the nozzle 4 moves outward, the pressure in the annular chamber 100 decreases, the one-way valve opens automatically, and the fluid in the pressure relief return chamber 45 flows out from the outlet 451 and returns to the annular chamber 100.

[0044] The pulverizer 2 is located inside the pulverizing chamber 10, below the water inlet 10c and above the discharge port 10b, and can operate under the drive of the drive mechanism 3 to pulverize kitchen waste entering from the feed port 10a. In this embodiment, the pulverizer 2 is a conventional grinding disc, and the drive mechanism 3 is a conventional motor. The motor shaft extends upward and is connected to the center of the grinding disc to drive the grinding disc to rotate. The specific structure of the grinding disc and the principle of pulverizing kitchen waste are the same as in the prior art and will not be described in detail here.

[0045] In the specification and claims of this utility model, terms indicating direction, such as "upper," "lower," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0046] The term "radial" is also used in the specification and claims of this utility model, meaning basically along the inside and outside direction, and is not limited to the radial direction that passes through the center of the circle, but can also be slightly deviated from the radial direction.
