Description

Technical Field

[0001] This invention relates to the field of household food waste disposers, and particularly to a pusher for a household food waste disposer and a household food waste disposer using the pusher. Background Technology

[0002] With the implementation of domestic garbage sorting policies, not only has the sales of sorting garbage bins increased significantly, but household food waste disposers (also known as "kitchen waste disposers" or "food waste disposers") have also been increasingly accepted by families. This is especially true for those installed under the kitchen sink drain. These typically include an inlet connected to the sink drain, a grinding chamber, a blade assembly within the grinding chamber, and an outlet connected to the drain pipe. This type of disposer uses the blade assembly to pulverize food waste in the grinding chamber and discharge it directly into the sewer, thus preventing the growth of bacteria, insects, and unpleasant odors caused by prolonged storage of food waste in the kitchen.

[0003] Before a household food waste disposer can operate, food waste needs to be fed into the grinding chamber through the inlet. Vegetable leaves, fruit peels, bones, etc., can easily clog the inlet, requiring the operator to handle them by hand. This means that the hands will directly come into contact with the food waste, which is both troublesome and unhygienic.

[0004] To address this, Chinese invention patent CN202316485U (application number 201120424005.9), entitled "Feeding Inlet Cover of Food Waste Disposer," adds a push rod mechanism to the existing cover to push food waste into the food waste disposer's feeding inlet. Specifically, the feeding inlet cover includes a hollow blocking body with a circular handle at the top, an annular protruding edge extending outwards in the middle, and a push rod sleeve at the bottom. A support rod is formed between the bottom of the push rod sleeve and the top of the circular handle. An annular sealing ring is fitted onto the annular protruding edge of the blocking body. Therefore, this invention uses the support rod and the cover to push food waste from the sink into the food waste disposer's feeding inlet. After processing the food waste, the blocking body is placed back into the feeding inlet. It is evident that this patent operates on a "dry" basis, meaning that no additional water is injected into the grinding chamber during the grinding process. This results in a relatively high workload for the motor and consequently, relatively high noise levels.

[0005] Therefore, a food waste disposer that can continuously add water while working was developed. Chinese invention patent CN216552243U (application number 202122487074.0), entitled "A Plug and Food Waste Disposer", discloses a plug that can be used with this type of new food waste disposer. It includes a plug body and a plug assembly. The plug body is configured to block the entrance of the grinding chamber. The plug body is provided with a first through hole and a sealing part. The plug assembly passes through the plug body and is provided with a second through hole. The plug assembly can rotate relative to the plug body so that the second through hole can selectively face the first through hole or the sealing part. The plug assembly includes a cover body and a column (with a pointed tip) provided on the side of the plug body facing the grinding chamber. This invention uses a plug assembly to replace manual labor in pushing food waste into the grinding chamber inlet and pressing it into the grinding chamber. When the processor is working, if water needs to be added, the second through hole is aligned with the first through hole on the plug body so that the plug is in a water-filled state. At this time, there is no gap between the plug and the grinding chamber inlet, and the connection with the receiving cavity is achieved only through the first and second through holes. This improves the sealing and noise reduction effect of the grinding chamber while meeting the need for water to be supplied to the grinding chamber. If water is not needed, the second through hole is aligned with the sealing part so that the plug is in a sealed state. At this time, the grinding chamber inlet is completely closed, further improving the sealing and noise reduction effect of the grinding chamber.

[0006] However, since the invention only has through holes in the plug used to seal the entrance of the grinding chamber, in actual use, the water flowing in from the through holes of the plug can only reach the grinding area of ​​the grinding chamber by its own weight through the gradual penetration of the layers of food waste. Due to the limited space under the sink, the grinding chamber space of these household food waste disposers is not large, but there is a lot of food waste in the house. Users often need to make the disposer work repeatedly for multiple cycles. Therefore, they often fill the grinding chamber with food waste and then cover the plug (at this time, the tip of the plug assembly will be inserted into the food waste) before starting the disposer to work.

[0007] On the other hand, the cutting tool assembly is usually located in the lower middle part of the grinding chamber, thus forming the grinding working area in the vicinity. Due to the blockage of food waste, the water entering the grinding chamber from the feed inlet can only reach the grinding working area at a very slow speed. Therefore, at least in the initial stage of each working cycle, the water in the grinding working area is unevenly distributed. At this time, not only is the noise of the cutting tool assembly crushing the waste loud, but the effective power output of the motor is also high, which further increases the noise. At the same time, the service life of the motor will also be reduced and the grinding effect will be poor. Summary of the Invention

[0008] The first technical problem to be solved by the present invention is to provide a pusher for a household food waste processor that enables water to quickly reach the grinding working area.

[0009] The second technical problem to be solved by the present invention is to provide a pusher for a household food waste processor that can spray water at high speed towards the grinding work area with additional water pressure in addition to its own weight.

[0010] The third technical problem to be solved by the present invention is to provide a pusher for a household food waste processor that can effectively reduce noise leakage when the processor is working without the need for an additional sealing component.

[0011] The fourth technical problem to be solved by the present invention is to provide a household food waste processor that uses the above-mentioned pusher.

[0012] The technical solution adopted by this invention to solve the first technical problem is: a pusher for a household food waste disposer, characterized in that it includes:

[0013] The mounting base is used to fit into the feed inlet of the aforementioned household food waste processor;

[0014] The pusher includes a bottom wall located below the mounting base and a peripheral wall extending upward along the edge of the bottom wall, thus defining a cavity with an open upper end. The upper end of the peripheral wall engages with the central portion of the mounting base, and a water outlet is provided on the bottom wall and / or the peripheral wall adjacent to the bottom wall. A first water inlet is provided on the upper part of the peripheral wall.

[0015] The technical solution adopted by the present invention to solve the second technical problem is as follows: it also includes:

[0016] The push rod is inserted into the cavity of the pusher through the opening in a manner that allows it to move up and down reciprocally;

[0017] A piston is located at the lower part of the push rod and can move up and down within the cavity of the pusher as the push rod moves up and down. At least one section of the inner diameter of the cavity of the pusher corresponds to the piston and matches the outer diameter of the piston. Thus, by moving the push rod up and down, the piston and the cavity wall of the corresponding section of the pusher slide and seal, allowing the water from the first water inlet to be sprayed at high speed with additional water pressure in addition to its own weight into the cavity of the pusher in the grinding working area. The increased water flow rate further reduces the noise in the grinding working area and makes it easier to flush the food residue after grinding in the grinding working area to the discharge port of the processor. At the same time, when the pressurized water jets out of the water outlet at high speed, it also flushes out the food waste that is blocked in the water outlet when the pusher is pushed down, thus cleaning the pusher.

[0018] To facilitate limiting the position of the push rod, preferably, the cavity of the pusher has at least a section of its inner diameter that matches the outer diameter of the push rod at the location corresponding to the push rod.

[0019] To facilitate increasing the water flow velocity into the piston chamber, preferably, the outer diameter of the piston is larger than the outer diameter of the push rod, and the cavity of the pusher includes, from top to bottom: a guide cavity with an inner diameter matching the outer diameter of the push rod, a buffer cavity with an inner diameter larger than the outer diameter of the piston, and a piston cavity with an inner diameter matching the outer diameter of the piston; the first water inlet is formed on the cavity wall of the buffer cavity.

[0020] To facilitate the flow of water into the first inlet hole, preferably, the buffer cavity has a first transition section with a gradually decreasing inner diameter at the connection point with the guide cavity, and the first inlet hole is formed on the cavity wall of the first transition section.

[0021] Preferably, the buffer chamber has a second transition section with a gradually decreasing inner diameter at the connection point with the piston chamber. In this way, after the piston is lifted away from the piston chamber and enters the buffer chamber, the water in the buffer chamber can enter the piston chamber as quickly as possible, so as to ensure continuous water output when the piston moves up and down.

[0022] To increase the spray area of ​​the water outlet, preferably, the cavity of the pusher has a water outlet cavity with an inner diameter larger than the outer diameter of the piston between its bottom wall and the piston cavity, and the water outlet hole is opened on the bottom wall and / or the peripheral wall of the water outlet cavity.

[0023] The technical solution adopted by the present invention to solve the third technical problem is as follows: the mounting base includes a ring-shaped main body, a hollow tube column located in the center of the main body, and a rib connecting the two, and these three together define the second water inlet hole; the pusher part matching the push rod is the upper end of the pusher part and is engaged with the hollow tube column, and the inner cavities of the two are interconnected.

[0024] Preferably, the mounting base and the pusher are integrally injection molded parts.

[0025] The technical solution adopted by the present invention to solve the fourth technical problem is: a household waste food processor using the pusher, including a feed inlet, characterized in that: the mounting base is detachably installed at the feed inlet.

[0026] Compared with the prior art, the advantages of the present invention are as follows: The pusher is placed inside the feed inlet of the household food waste processor via a mounting base. The pusher includes a bottom wall located below the mounting base and a peripheral wall extending upward along the edge of the bottom wall, thus defining a cavity with an open upper end. A water outlet is provided on the bottom wall and / or the peripheral wall adjacent to the bottom wall, and a first water inlet is provided on the upper part of the peripheral wall. When the grinding chamber is filled with food waste, the pusher located at the processor feed inlet is inserted into the waste. In the initial stage of each working cycle of the household food waste processor, the pusher allows water to quickly reach the grinding working area, reducing the noise of the blade assembly crushing the waste, reducing the effective power output of the motor, further reducing noise while increasing the motor's service life, and achieving excellent grinding results.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] See Figures 1 to 9The figure shows a preferred embodiment of the pusher of the present invention for a household food waste processor, including a mounting base 4, a push rod 2, a piston 21 and a pusher 1.

[0038] Mounting base 4 includes a ring-shaped main body 40, a hollow tube column 43 located in the center of the main body 40, and a rib 42 connecting the two, and these three together define the second water inlet 41. See also Figure 5 , Figure 8 As shown, the mounting base 4 is located inside the feed inlet 51 of the household food waste processor 5, and the mounting base 4 and the household food waste processor 5 are detachably connected. In this embodiment, the mounting base 4 and the pusher 1 are integrally injection molded parts. In other embodiments, the mounting base 4 and the pusher 1 can be separately molded and then connected together.

[0039] The pusher 1 includes a bottom wall 13 located below the mounting base 4 and a peripheral wall 12 extending upward along the edge of the bottom wall 13, thus defining a cavity 10 with an upper opening 11. The upper end of the peripheral wall 13 engages with the central portion of the mounting base 4, and a water outlet 131 is provided on the bottom wall 13. A first water inlet 111 is provided on the upper part of the peripheral wall 12. See also Figure 3 , Figure 6 , Figure 9 As shown, the cavity 10 of the pusher component includes, from top to bottom: a guide cavity 1a with an inner diameter matching the outer diameter of the push rod 2; a buffer cavity 1b with an inner diameter larger than the outer diameter of the piston 21; a piston cavity 1c with an inner diameter matching the outer diameter of the piston 21; and a water outlet cavity 1d with an inner diameter larger than the outer diameter of the piston 21, located between the bottom wall 13 and the piston cavity 1c. The upper end of the pusher component 1 is connected to the hollow tube column 43. The guide cavity 1a is the inner cavity of the upper end, and the top opening of the guide cavity 1a is the vent 11. The guide cavity 1a is interconnected with the inner cavity of the hollow tube column 43. The buffer cavity 1b has a first transition section 121 with a gradually decreasing inner diameter at the connection with the guide cavity 1a, and the first water inlet 111 is formed on the cavity wall of the first transition section 121. The buffer cavity 1b has a second transition section 122 with a gradually decreasing inner diameter at the connection with the piston cavity 1c.

[0040] The push rod 2 is inserted into the cavity 10 of the pusher through the hollow tube column 43 and the opening 11 in a way that allows it to move up and down. The piston 21 is located at the lower part of the push rod 2. The outer diameter of the piston 21 is larger than the outer diameter of the push rod 2. As the push rod 2 moves up and down, it can move up and down within the cavity 10 of the pusher, and can be in a state of being disengaged from the piston cavity 1c or in a state of sliding and sealing connection with the inner wall of the piston cavity 1c.

[0041] Working status: Before the household food waste processor 5 starts working, first remove the pusher from the feed inlet 51. Use the pusher 1 to push the food waste in the sink into the grinding chamber of the household food waste processor 5 through the feed inlet 51. After the grinding chamber is full of food waste, install the pusher back into the feed inlet 51. Insert the pusher into the food waste. Turn on the faucet and start the household food waste processor 5. Water flows into the cavity 10 through the second water inlet 41 and the first water inlet 111. At the same time, the pusher 2 moves up and down relative to the mounting base 4. Water flows from the buffer cavity 1b into the piston cavity 1c and is pushed into the outlet cavity 1d by the piston 21. Finally, it is sprayed out from the outlet hole 131. This pusher allows water to quickly reach the grinding area at the beginning of each work cycle, avoiding obstruction from layers of food waste. The high-speed, pressurized water jet reduces noise from the blade assembly crushing waste and the increased power output of the motor. Furthermore, the mounting base 4 further blocks noise transmission from the grinding chamber, further minimizing noise leakage during operation. The high-speed water flow also quickly flushes the ground food residue towards the discharge port, improving the efficiency of each work cycle.
