Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and in particular to a kitchen waste treatment device. 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 across 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 generally consist of a corrosion-resistant grinding chamber, stainless steel grinding hammers, and a stainless steel grinding disc. They utilize a high-speed rotating permanent magnet motor to drive the grinding disc in the grinding chamber. Food waste collides with each other under centrifugal force, being ground into fine particles in a very short time and discharged through the water pipes, thus achieving the effects of cleaning the environment and eliminating odors, providing great convenience to people's lives. However, since the grinding disc rotates in one direction during operation, the debris on the grinding disc also rotates in one direction, resulting in insufficient impact with the grinding disc. The grinding effect needs to be further improved. Furthermore, the debris is easily thrown onto the inner wall of the grinding chamber under the action of centrifugal force, contaminating the inner wall of the grinding chamber. After long-term use, a lot of debris remains on the inner wall of the grinding chamber, and cleaning is relatively inconvenient. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a kitchen waste treatment device that improves the grinding effect by introducing water jets into the grinding chamber, 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 treatment device includes a housing and a grinding hood installed inside the housing. A rotatable grinding disc is installed inside the grinding hood. A feeding port is provided at the top of the grinding hood, and a discharge port is provided at the bottom of the grinding hood. The discharge port is located below the grinding disc. The device is characterized in that: an annular fixed sprayer is installed inside the grinding hood. The fixed sprayer is located above the grinding disc. Water outlet holes are distributed circumferentially on the fixed sprayer. A water inlet cavity is formed between the fixed sprayer and the inner wall of the grinding hood. A water inlet communicating with the water inlet cavity is provided on the grinding hood. A rotating disc is installed inside the water inlet cavity. The rotating disc can rotate under the action of the water flow flowing in from the water inlet. Furthermore, the rotation direction of the rotating disc is opposite to the rotation direction of the grinding disc.

[0005] The fixed sprayer can have various structures. Preferably, the fixed sprayer includes a connecting ring and a water outlet ring extending radially outward from the lower edge of the connecting ring. The upper part of the connecting ring is fixed to the feeding port, and the rotating disk is sleeved on the lower part of the connecting ring and can rotate relative to the connecting ring. The outer periphery of the water outlet ring abuts against the inner wall of the grinding cover, and the water outlet hole is provided on the water outlet ring. In this way, water will not flow out from the outer periphery of the water inlet chamber, the pressure holding effect of the water inlet chamber is better, which is conducive to the rotation of the rotating disk, thereby improving the spraying effect.

[0006] In order to ensure that the water outlets can discharge water evenly, the water outlets are distributed in at least two rings, an outer ring and an inner ring. The water outlets of the outer ring and the inner ring are evenly distributed and correspond one-to-one along the circumferential direction. Furthermore, along the direction of water flow, the water outlets of the outer ring are located in front of the water outlets of the inner ring.

[0007] In order to install the fixed sprayer at the feeding port, the inner wall of the feeding port is formed with a first threaded portion, and the upper part of the connecting ring is formed with a second threaded portion, and the first threaded portion and the second threaded portion are threadedly connected.

[0008] In order to ensure that the water flowing into the inlet can smoothly drive the rotating disk to rotate, the water inlet direction is parallel to the tangential direction of the rotating disk.

[0009] In order for the water flow to impact the rotating disk, a water-blocking part is provided on the outer periphery of the rotating disk, and the water-blocking part is distributed at intervals along the circumference of the rotating disk.

[0010] Further preferably, the water-blocking part includes a front water-blocking plate, a rear water-blocking plate, and an upper connecting plate disposed between the front and rear water-blocking plates. The corresponding parts of the front water-blocking plate, the rear water-blocking plate, the upper connecting plate, and the water outlet ring form a cavity, and the rear water-blocking plate constitutes a water flow impact surface. In this way, the cavity formed by the front water-blocking plate, the rear water-blocking plate, the upper connecting plate, and the water outlet ring contains less water, which allows the rotating disc to rotate more smoothly and enables intermittent water output from the fixed sprayer.

[0011] Further preferably, the grinding shroud includes an upper grinding shroud and a lower grinding shroud mounted at the bottom of the upper grinding shroud. The feeding port is located at the top of the upper grinding shroud, the discharge port is located on the side of the lower grinding shroud, the grinding disc is located at the bottom of the upper grinding shroud, and a motor is mounted below the lower grinding shroud. The output shaft of the motor passes vertically upward through the lower grinding shroud and is connected to the grinding disc. This design facilitates the installation of the grinding disc and allows it to rotate under the drive of the motor.

[0012] To improve the grinding effect, the grinding disc includes an upper grinding disc and a lower grinding disc fixed to the bottom of the lower grinding disc. The outer peripheral edge of the lower grinding disc is formed with a first toothed ring, and the inner peripheral wall of the lower grinding cover is provided with a second toothed ring protruding inward. The first toothed ring is located above the second toothed ring and has a gap between it and the inner wall of the lower grinding cover. Furthermore, the vertical projection of the outer peripheral edge of the first toothed ring falls on the second toothed ring.

[0013] In order to control the water inlet, a water inlet pipe is connected to the water inlet and extends outward from the machine casing. A water inlet control unit is installed inside the machine casing.

[0014] In order to install the waste disposal device on the water tank, a connector assembly is installed at the feed inlet.

[0015] Compared with existing technologies, the advantages of this invention are as follows: This food waste treatment device installs a fixed sprayer and a rotating disc inside the grinding hood. The rotating disc rotates under the thrust of water flow, and its rotation direction is opposite to that of the grinding disc. This results in better pressure retention in the water inlet chamber. The water flow in the water inlet chamber generates a spraying effect through the water outlet on the fixed sprayer. The water flow is directly sprayed onto the grinding working area, introducing a water jet into the grinding chamber, agitating the food waste, and improving the grinding effect. At the same time, the water sprayed from the fixed sprayer can also spray onto the inner wall of the grinding hood, effectively washing away the food waste splashed onto the inner wall of the grinding hood by the grinding disc, improving the grinding effect and increasing the self-cleaning effect. In addition, compared with directly spraying water into the center of the grinding disc, the spraying method can reduce the motor load and help extend the motor's service life.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 9 As shown, the kitchen waste treatment device of this embodiment includes a housing 1, inside which a grinding hood 2 is installed. Inside the grinding hood 2, a grinding disc 3 and a ring-shaped fixed sprayer 4 are installed, with the fixed sprayer 4 positioned above the grinding disc 3. The grinding hood 2 includes an upper grinding hood 200 and a lower grinding hood 201 that fit together vertically, connected by corresponding flanges. A motor 7 is installed below the lower grinding hood 201. The output shaft of the motor 7 passes vertically upward through the lower grinding hood 201 and is connected to the grinding disc 3. During operation, the grinding disc 3 rotates under the drive of the motor 7. A feeding port 21 is provided at the top of the upper grinding hood 200, and a discharge port 22 is provided on the side of the lower grinding hood 201, located below the grinding disc 3. A connector assembly 10 is installed at the feeding port 21 for mounting on a water tank, and a discharge pipe 11 is connected to the discharge port 22 to discharge the treated waste into a drain pipe.

[0027] like Figures 5 to 7 As shown, the inner wall of the feeding port 21 is formed with a first threaded portion 211. The fixed sprayer 4 includes a connecting ring 42 and a water outlet ring 43 extending radially outward from the lower edge of the connecting ring. The upper part of the connecting ring 42 is formed with a second threaded portion 421. The first threaded portion 211 and the second threaded portion 421 are threadedly connected, so that the fixed sprayer 4 is fixed on the feeding port 21. The water outlet ring 43 has circumferentially distributed water outlet holes 41. In this embodiment, the water outlet holes 41 are arranged in three rings, and the water outlet holes of the inner ring, the middle ring, and the outer ring are evenly distributed circumferentially and correspond one-to-one. Furthermore, along the water flow direction, the water outlet holes of the outer ring are located in front of the water outlet holes of the middle ring, and the water outlet holes of the middle ring are located in front of the water outlet holes of the inner ring.

[0028] Furthermore, the outer periphery of the water outlet ring 43 abuts against the inner wall of the upper grinding cover 200, forming a water inlet cavity 5 between the fixed sprayer 4 and the inner wall of the upper grinding cover 200. A water inlet 23 communicating with the water inlet cavity 5 is provided on the upper grinding cover 200, and a water inlet pipe 8 is connected to the outside of the water inlet 23, extending to the outside of the housing 1. A water inlet control unit 9 is installed inside the housing 1 to control the water intake through the water inlet 23.

[0029] A rotating disk 6 is installed inside the water inlet chamber 5. The rotating disk 6 is sleeved on the lower part of the connecting ring 42. The rotating disk 6 rotates under the action of the water flow into the water inlet 23. The water inlet direction of the water inlet 23 is parallel to the tangential direction of the rotating disk 6. Furthermore, the rotation direction of the rotating disk 6 is opposite to the rotation direction of the grinding disk 3.

[0030] In this embodiment, the outer periphery of the rotating disk 6 is provided with a water-blocking part 61. There are three water-blocking parts 61, which are evenly distributed along the circumference of the rotating disk 6. The water-blocking part 61 includes a front water-blocking plate 611, a rear water-blocking plate 612, and an upper connecting plate 613 disposed between the front water-blocking plate and the rear water-blocking plate. The corresponding parts of the front water-blocking plate 611, the rear water-blocking plate 612, the upper connecting plate 613, and the water outlet ring 43 below the upper connecting plate form a cavity 62. The rear water-blocking plate 611 constitutes a water flow impact surface. The cavity 62 structure has two advantages: firstly, the cavity contains less water, which allows the rotating disk to rotate more smoothly; secondly, it enables intermittent water output from the fixed sprayer, which is beneficial for improving the grinding effect.

[0031] like Figure 9 As shown, the grinding disc 3 in this embodiment includes an upper grinding disc 31 and a lower grinding disc 32 fixed to the bottom of the upper grinding disc. A first toothed ring 321 is formed on the outer peripheral edge of the lower grinding disc 32, and a second toothed ring 202 protrudes inward from the inner peripheral wall of the lower grinding cover 201. The first toothed ring 321 is positioned above the second toothed ring 202 and has a gap between it and the inner wall of the lower grinding cover 201. Furthermore, the vertical projection of the outer peripheral edge of the first toothed ring 321 falls onto the second toothed ring 202.

[0032] When the waste disposal device is working, the tangentially positioned water inlet 23 utilizes the water pressure generated by the tap water itself or the water pressure boosted by the pump to generate a tangential thrust. The rotating disc 6 rotates under the thrust of the water flow, and the water in the inlet chamber 5 sprays through the outlet hole 41 to create a spraying effect. Because the rotation direction of the rotating disc 6 is opposite to that of the grinding disc 3, the water flowing from the outlet hole 41, when sprayed directly onto the grinding area, can more thoroughly agitate the kitchen waste, improving the grinding effect. When the water pressure at the inlet 23 increases, the rotation speed of the rotating disc 6 increases, resulting in a better water flow impact effect. Furthermore, the structure of the rotating disc 6 also allows for intermittent water output from the fixed sprayer 4. In addition, the water sprayed from the fixed sprayer 4 also sprays onto the inner wall of the grinding hood 2, effectively washing away the kitchen waste splashed onto the inner wall of the grinding hood 2 by the grinding disc 3, improving the grinding effect and providing a self-cleaning function.
