A food waste disposer

Abstract

A food waste disposer includes a housing, an annular stepped portion formed on the side wall of an upper grinding shroud, a first water outlet located above the annular stepped portion, and a second water outlet on the annular stepped portion. A water inlet shroud with a water inlet is installed on the outer periphery of the upper grinding shroud, and a liquid-separating chamber is formed between the water inlet shroud and the upper grinding shroud. The first water outlet is always connected to the water inlet through the liquid-separating chamber. A liquid-separating ring capable of vertical movement is installed within the liquid-separating chamber, and the second water outlet is connected to or blocked from the water inlet through the vertical movement of the liquid-separating ring. When the food waste disposer is turned on, the liquid-separating ring is in the lower position, and water flows out from the first water outlet, achieving a wall cleaning effect. When food waste is put into the grinding chamber, the turbulence of the food causes the liquid-separating ring to be pushed upwards, and the water flow also directly shoots towards the grinding working area through the second water outlet, suppressing the food, increasing turbulence, and enhancing the grinding effect.

Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and in particular to a food waste processor. Background Technology

[0002] As people's living standards improve, the demand for smart kitchens is increasing, leading to the widespread use of smart appliances such as smart rice cookers and smart dishwashers. Kitchen waste, mostly organic matter, is prone to bacterial growth, producing unpleasant odors, and its complex composition makes sorting difficult, making it a major component of household waste and thus requiring corresponding products for processing. With the implementation of waste sorting policies in various regions, sales of sorting bins and waste disposers have increased significantly, and food waste disposers are being purchased and used by more and more users. Existing food waste disposers come in various types, among which direct-discharge disposers grind waste and discharge it directly into the sewer, providing some convenience. However, most existing food waste disposers rely on a tap above the sink for water supply. During use, users often place the feeder at the feeding port due to noise, which affects water intake and thus the grinding effect. Furthermore, if the feeding port is left open, water will directly enter the center of the grinding components, be thrown to the top of the grinding chamber, and finally flow to the area where the food waste is being ground. This consumes the effective power output of the motor and also results in poor grinding performance. To address the aforementioned issues, existing technologies disclose food waste disposers with automatic water intake; however, these disposers all employ a single-hole water inlet and outlet, which fails to effectively aid the grinding process. Therefore, further improvements to existing food waste disposers are necessary. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a food waste processor that can improve the turbulence and grinding effect, in view of the above-mentioned existing technology.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: The kitchen waste processor includes a housing and a grinding hood installed inside the housing. A grinding disc is installed inside the grinding hood. The grinding hood includes an upper grinding hood and a lower grinding hood. A feeding port is opened at the top of the upper grinding hood, and a discharge port is opened on the lower grinding hood. The upper grinding hood is characterized in that: an annular stepped portion is formed on the side wall of the upper grinding hood, and a first water outlet is opened on the upper grinding hood at intervals along the circumference. The first water outlet is located above the annular stepped portion. A second water outlet is opened on the annular stepped portion. A water inlet hood is installed on the outer periphery of the upper grinding hood. The water inlet hood has a water inlet. A liquid separation chamber is formed between the water inlet hood and the upper grinding hood. The first water outlet is always connected to the water inlet through the liquid separation chamber. A liquid separation ring that can move up and down is installed in the liquid separation chamber. The second water outlet is connected to or blocked from the water inlet through the up and down movement of the liquid separation ring.

[0005] Preferably, the annular stepped portion has a downward vertical through hole, and the bottom of the liquid-distributing ring has a pin that can be inserted into and pass through the downward vertical through hole. In this way, the high-speed rotation of the grinding disc, combined with the water flow from the first outlet, causes the kitchen waste and water to rotate and turbulent. The turbulence of the food causes the pin of the liquid-distributing ring to be lifted, thereby causing the liquid-distributing ring to move upward.

[0006] Further preferably, a supporting step extends radially outward on the side wall of the upper grinding shroud below the first outlet. An annular wall extends upward from the outer edge of the supporting step, and a water passage hole is formed in the annular wall. The liquid-distributing ring has vertically distributed annular baffle walls and a first radial protrusion extending radially outward from the upper edge of the annular baffle walls. The annular baffle walls are located on the inner side of the annular wall, the first radial protrusion is located above the annular wall, and the ejector pin is located at the bottom of the annular baffle walls. The outer periphery of the first radial protrusion abuts against the inner side wall of the inlet shroud. Thus, after the liquid-distributing ring moves upward, the second outlet is opened, allowing water flowing in from the inlet to both exit from the first outlet and pass through the water passage hole before exiting from the second outlet.

[0007] The water passage holes can be arranged in various ways. Preferably, the water passage holes are distributed at intervals along the circumference of the annular wall.

[0008] In order to enable the ejector pin to be smoothly lifted under the turbulence, an upper vertical through hole is provided on the support step. The upper vertical through hole and the lower vertical through hole correspond one-to-one. The ejector pin is movably disposed in the upper vertical through hole and the lower vertical through hole.

[0009] In order to close the second outlet when the liquid separating ring moves downward and open the second outlet when it moves upward, the bottom of the annular water-blocking wall abuts against the supporting step when the liquid separating ring is in the fallen state, and a water passage gap is formed between the bottom of the annular water-blocking wall and the supporting step when the liquid separating ring is in the raised state.

[0010] Further preferably, the top of the annular wall has an outward flange, and the first radial protrusion is located above the outward flange. When the separating ring falls, its first radial protrusion abuts against the outward flange.

[0011] To prevent water leakage between the water inlet cover and the upper grinding cover, the annular stepped portion has a second radial boss extending outward, and the bottom outer side of the water inlet cover has a radial flange extending outward. The radial flange is located above the second radial boss, and a sealing ring is installed between the two.

[0012] To improve sealing, the outer periphery of the second radial boss has an upward flange, and the outer periphery of the radial flange abuts against the upward flange.

[0013] The water inlet can be set at multiple different positions of the water inlet cover. Preferably, the water inlet of the water inlet cover is set at the top of the water inlet cover, and the vertical projection of the water inlet falls on the first radial protrusion.

[0014] In order to smoothly drive the grinding disc to rotate, the grinding disc is located at the bottom of the upper grinding cover, and a motor is installed below the lower grinding cover. The output shaft of the motor passes vertically upward through the lower grinding cover and is connected to the grinding disc.

[0015] In order to install the garbage disposer on the sink, a connector assembly is installed at the feed inlet.

[0016] Compared with the prior art, the advantages of the present invention are as follows: a liquid separation chamber is formed between the water inlet cover and the upper grinding cover of the food waste disposer. The first water outlet on the upper grinding cover is always connected to the water inlet of the water inlet cover through the liquid separation chamber. The water outlet of the second water outlet is controlled by the liquid separation ring in the liquid separation chamber. When the machine is turned on, the liquid separation ring is in the lower position, and water comes out from the first water outlet to achieve the effect of cleaning the wall. The first water outlet has a small area and a small water volume, which has a certain water-saving effect. When food waste is put into the grinding chamber, the high-speed rotation of the grinding motor and the water flow from the first water outlet cause the food waste and water to rotate and turbulent. The turbulence of the food causes the liquid separation ring to be pushed upward. The water flow also directly shoots into the grinding working area through the second water outlet, which suppresses the food being ground. The water outlet of the second water outlet increases the source of water flow disturbance, enhances the turbulence, and can increase the grinding effect. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 5 As shown, the food waste disposer of this embodiment includes a housing 1, inside which is a grinding hood. A grinding disc 4 is installed inside the grinding hood. Specifically, the grinding hood includes an upper grinding hood 2 and a lower grinding hood 3. The grinding disc 4 is located at the bottom of the upper grinding hood 2. A motor 10 is installed below the lower grinding hood 3. The output shaft of the motor 10 passes vertically upward through the lower grinding hood 3 and is connected to the grinding disc 4. The grinding disc 4 rotates under the drive of the motor 10. A feeding port 20 is opened at the top of the upper grinding hood 20, and a connector assembly 11 is installed at the feeding port 20. The food waste disposer is installed on the sink via the connector assembly 11. A discharge port 30 is opened on the side of the lower grinding hood 3, and a discharge pipe (not shown in the figure) is connected to the discharge port 30. The processed waste is discharged into the drain pipe through the discharge pipe. The above structure is a conventional structure of existing food waste disposers and will not be described further here.

[0028] In this embodiment, an annular stepped portion 21 is formed on the side wall of the upper grinding cover 2. First water outlets 22 are spaced circumferentially on the upper grinding cover 2, located above the annular stepped portion 21. Second water outlets 23 are formed on the annular stepped portion 21, with the water outlet direction of the second water outlet 23 facing downwards. A water inlet cover 5 is installed on the outer periphery of the upper grinding cover 2. The water inlet cover 5 has a water inlet 51, and a liquid distribution chamber 6 is formed between the water inlet cover 5 and the upper grinding cover 2. The first water outlet 22 is always connected to the water inlet 51 through the liquid distribution chamber 6. A liquid distribution ring 7 is installed inside the liquid distribution chamber 6, and the liquid distribution ring 7 can move up and down. The second water outlet 23 is connected to or blocked from the water inlet 51 through the up and down movement of the liquid distribution ring 7. The upper grinding cover 2 is provided with an annular stepped part 21. On the one hand, it is to form a liquid separation chamber 6 between itself and the water inlet cover 5, and to form a second water outlet 23 with the water outlet direction facing downward. On the other hand, it can effectively prevent splashing during the grinding process of waste, increase the probability of waste colliding with the grinding disc, and improve the grinding effect.

[0029] A support step 25 extends radially outward on the side wall of the upper grinding cover 2 below the first water outlet 22. An annular wall 26 extends upward from the outer edge of the support step 25. Water passage holes 261 are opened on the annular wall 26 and are distributed at intervals along the circumference of the annular wall 26. The top of the annular wall 26 has an outwardly turned edge 262.

[0030] The liquid separating ring 7 has vertically distributed annular water-retaining walls 71 and a first radial protrusion 72 extending radially outward from the upper edge of the annular water-retaining walls. The annular water-retaining walls 71 are located inside the annular wall 26, and the first radial protrusion 72 is located above the outer flange 262. The outer periphery of the first radial protrusion 72 abuts against the inner wall of the water inlet cover 5. A pin 73 extends downward from the bottom of the annular water-retaining wall 71. An upper vertical through hole 251 is opened on the support step 25 of the upper grinding cover 2, and a lower vertical through hole 24 is opened on the annular step portion 21. The lower vertical through holes 24 correspond one-to-one with the upper vertical through holes 251 and are aligned vertically. The pin 73 is movably disposed within the upper vertical through holes 251 and the lower vertical through holes 24.

[0031] In this embodiment, the water inlet cover 5 has a water inlet 51 located at its top, and the vertical projection of the water inlet 51 falls on the first radial boss 72. The annular stepped portion 21 has an outwardly extending second radial boss 27, and the outer bottom of the water inlet cover 5 has an outwardly extending radial flange 52, which is located above the second radial boss 27 and the two are sealed together by a sealing ring 9. This prevents water leakage between the bottom of the water inlet cover 5 and the upper grinding cover 2. In addition, the outer periphery of the second radial boss 27 has an upward flange 271, and the outer periphery of the radial flange 52 abuts against the upward flange 271, which makes the seal more reliable.

[0032] like Figure 6and Figure 7 As shown, when the machine is turned on, the separating ring 7 is in the lowered state, and the bottom of the annular water-blocking wall 71 abuts against the supporting step 25. Water flowing into the separating chamber 6 from the inlet 51 can only flow out through the first outlet 22 and then into the upper grinding cover 2, achieving the effect of cleaning the grinding cover wall. The first outlet 22 has a small area and a small water flow, thus achieving a certain water-saving effect. Due to the obstruction of the annular water-blocking wall 71, water cannot flow to the second outlet 23. At this time, the pin 73 of the separating ring 7 passes downward through the upper vertical through hole 251 and the lower vertical through hole 24 and is exposed inside the upper grinding cover 2. (See...) Figure 7 .

[0033] like Figure 8 and Figure 9 As shown, when kitchen waste is put into the grinding chamber, the high-speed rotation of the motor 10, combined with the water flow from the first outlet 22, causes the kitchen waste and water to rotate and turbulent. The turbulence of the food causes the pin 73 of the separating ring 7 to be lifted, so that the separating ring 7 is in an elevated state. A water passage gap 8 is formed between the bottom of the annular water-blocking wall 71 and the supporting step 25. The water flowing into the separating chamber 6 from the inlet 51 can flow out through the first outlet 22 and into the upper grinding cover 2, and can also flow through the water passage gap 8 and the water passage hole 261 on the annular wall 26 to the second outlet 23. Finally, the water is directly sprayed into the grinding working area through the second outlet 23, which suppresses the food being ground. The water from the second outlet 23 increases the source of water flow disturbance, enhances the turbulence, and can increase the grinding effect.
