Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste treatment, in particular to a cleaning structure for a drainage pipe and a kitchen waste treatment device using the structure. Background Art

[0002] With the improvement of people's living standards and the development of the catering industry, the amount of kitchen waste is increasing. Kitchen waste usually includes spoiled vegetables and leftovers after meals. Compared with other household waste, kitchen waste is often accompanied by its own unique odor, and is more likely to attract flies and insects, or mold, breed bacteria, etc. At present, when people deal with kitchen waste, they usually flush the kitchen waste directly into the sewer or pack it in a convenient bag and throw it away. However, when operating this method, since kitchen waste contains a lot of grease, if it is directly flushed into the sewer or packed and thrown away, it is not only easy to pollute the environment, but also causes mosquitoes and flies to breed, stench and other problems.

[0003] Therefore, food waste disposers have gradually entered the kitchen, such as the "A kitchen waste disposal device" disclosed in the Chinese invention patent application with patent number CN202311410622.7 (publication number CN117248598A), which includes a garbage inlet, a water inlet, a backup garbage inlet, a garbage disposal chamber, a filter drain and a motor.

[0004] Food waste disposers generally grind food residues into small particles, which are then discharged into the household drainage system under the drive of water flow. In the related art, food waste disposers are usually flushed directly with tap water. When the tap water volume is insufficient, the crushed small particles will remain at the bottom of the drain pipe. Long-term accumulation will cause pipe blockage, resulting in poor user experience, and there is room for improvement. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a drainage pipe cleaning structure capable of flushing the drainage pipe in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a kitchen waste disposer using the above cleaning structure in view of the current status of the prior art.

[0007] The utility model solves the above-mentioned first technical problem by adopting a technical solution: a drainage pipe cleaning structure, comprising:

There is a distance between the outer circumferential wall of the spray pipe and the inner circumferential wall of the drain pipe. A plurality of spray holes are arranged on the circumferential wall of the spray pipe at intervals along its circumference. Along the water flow direction, the upstream end of the spray pipe is open and located downstream of the connecting port.

[0012] In order to improve the cleaning effect of the spray pipe on the drain pipe, a circle of retaining edges is provided in the spray pipe along its circumference, one end of the retaining edge is connected to the downstream end of the spray pipe, and the other end extends toward the upstream end of the spray pipe and is inclined in the direction of the center line of the spray pipe. The spray hole is at least partially located on the side of the retaining edge, and the retaining edge plays the role of rebounding water flow, so that the water flow is sprayed out from the spray hole to flush the drain pipe.

[0013] The spray holes include a plurality of first spray holes and a plurality of second spray holes. Along the water flow direction, the second spray holes are located downstream of the first spray holes.

[0014] Preferably, the second spray hole is arranged adjacent to the downstream end of the spray pipe to prevent garbage from accumulating at the bottom of the spray pipe.

[0015] If the water entering from the water inlet end of the drain pipe only flows out from the spray hole, the drainage volume will be small. Therefore, preferably, along the water flow direction, the downstream end of the spray pipe is open so that the water can also flow out from the downstream end of the spray pipe.

[0016] In order to facilitate the installation of the spray pipe, the drainage pipe includes a first water outlet pipe and a second water outlet pipe which are arranged and connected in sequence along the water flow direction.

The spray pipe can be arranged in the second water outlet pipe, and then the first water outlet pipe and the second water outlet pipe are connected. The connection between the first water outlet pipe and the second water outlet pipe is connected by a transition connection of an arc structure to ensure smooth flow of water. Preferably, the first water outlet pipe extends vertically.

[0017] In order to pump water into the water supply pipe, the cleaning structure also includes a water tank and a water pump. The water inlet of the water pump is connected to the water tank through the water inlet pipe, and the drain hole of the water pump is connected to the water inlet end of the water supply pipe.

[0021] Preferably, a grinding assembly is provided in the grinding chamber, the grinding assembly is connected to a driving mechanism, and the driving mechanism is also connected to an impeller. The driving mechanism can be used to drive not only the grinding assembly but also the impeller, so that there is no need to set up a separate driving mechanism for the grinding assembly and the impeller, and fewer parts are involved.

[0022] In the above scheme, the grinding chamber is located at the upper part of the housing, the pump housing is the lower part of the housing, the driving mechanism includes a driving member and an upper output shaft and a lower output shaft connected to the driving member, the driving member is located between the grinding chamber and the pump housing, the upper output shaft is connected to the grinding assembly, and the lower output shaft is connected to the impeller.

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] like Figures 1 to 7 As shown, the cleaning structure of the drain pipe of this preferred embodiment includes a drain pipe 1, a water supply pipe 2, a spray pipe 3, a water tank 4 and a water pump 5.

[0033] A connection port 11 is provided on the peripheral wall of the drain pipe 1, and the water outlet end of the water supply pipe 2 is connected to the connection port 11 on the drain pipe 1. The spray pipe 3 is provided in the drain pipe 1, and the spray pipe 3 extends along the axial direction of the drain pipe 1. Along the water flow direction, the upstream end of the spray pipe 3 is open and located downstream of the connection port 11. The water flowing into the water inlet end of the drain pipe 1 and the water flowing into the water supply pipe 2 can both flow out from the upstream end of the spray pipe 3.

[0034] There is a gap between the outer wall of the spray pipe 3 and the inner wall of the drain pipe 1. A plurality of spray holes are arranged on the peripheral wall of the spray pipe 3 at intervals along its circumference. A retaining edge 31 is arranged in the spray pipe 3 along its circumference. One end of the retaining edge 31 is connected to the downstream end of the spray pipe 3, and the other end extends toward the upstream end of the spray pipe 3 and is inclined in the direction of the center line of the spray pipe 3. The spray holes are at least partially located on the side of the retaining edge 31. The retaining edge 31 plays the role of rebounding water flow, so that water flows out from the spray holes to flush the drain pipe 1.

[0035] In this embodiment, Figure 4 , 6 As shown, the spray holes include a plurality of first spray holes 32 and a plurality of second spray holes 33. Along the water flow direction, the second spray holes 33 are located downstream of the first spray holes 32. The plurality of first spray holes 32 are arranged in sequence at intervals along the circumference of the spray pipe 3. The plurality of second spray holes 33 are arranged in sequence at intervals along the circumference of the spray pipe 3. Each first spray hole 32 extends along the axial direction of the spray pipe 3, so that the cleaning area of ​​the drain pipe 1 is large.

[0036] The second spray hole 33 is located beside the retaining edge 31 , and the water rebounded by the retaining edge 31 flows out from the second spray hole 33 ; in addition, the second spray hole 33 is arranged near the downstream end of the spray pipe 3 to prevent garbage from accumulating at the bottom of the spray pipe 3 .

[0037] If the water entering from the water inlet end of the drain pipe 1 only flows out from the spray hole, the drainage volume will be small. Therefore, along the water flow direction, the downstream end of the spray pipe 3 is open. Because the baffle 31 does not completely block the downstream end of the spray pipe 3, the water can flow out from the downstream end of the spray pipe 3.

[0038] In this embodiment, the drain pipe 1 includes a first water outlet pipe 12 and a second water outlet pipe 13 which are arranged and connected in sequence along the water flow direction. The connecting port 11 is arranged on the peripheral wall of the first water outlet pipe 12 adjacent to the downstream end. The spray pipe 3 is arranged at the upstream end of the second water outlet pipe 13. The spray pipe 3 can be arranged in the second water outlet pipe 13, and then the first water outlet pipe 12 and the second water outlet pipe 13 are connected. The connection between the first water outlet pipe 12 and the second water outlet pipe 13 is transitionally connected by an arc structure 121 to ensure smooth flow of water. Preferably, the first water outlet pipe 12 extends vertically, and the angle between the water supply pipe 2 and the first water outlet pipe 12 can be an acute angle, such as 60°, or a right angle.

[0039] The drain pipe 1 of this embodiment is connected to the discharge port of the food waste disposer. Of course, the drain pipe 1 can also be connected to the drain port of a sink or a dishwasher.

[0040] like Figure 5 As shown, the food waste disposer includes a shell 6 and a grinding assembly 7. The shell 6 has a grinding chamber 61 inside. The shell 6 is provided with a feed port 62 and a discharge port 63 connected to the grinding chamber 61. The water inlet end of the drain pipe 1 (i.e., the water inlet end of the first water outlet pipe 12) is connected to the discharge port 63, and the water in the grinding chamber 61 can be discharged from the discharge port 63.

[0041] A grinding assembly 7 is provided in the grinding chamber 61, and the grinding assembly 7 is connected to a driving mechanism 8. The grinding assembly 7 can adopt an existing structure to grind the garbage.

[0042] The water inlet hole 51 of the water pump 5 is connected to the water tank 4 through the water inlet pipe 52, and the drainage hole 53 of the water pump 5 is connected to the water inlet end of the water supply pipe 2. An existing liquid level sensor can be set in the water tank 4 to detect the water storage amount of the water tank 4 and replenish water in the water tank 4 in time.

[0043] The water pump 5 includes a pump casing 54 and an impeller 55 arranged in the pump casing 54. The water inlet hole 51 and the drain hole 53 are both arranged on the pump casing 54. The driving mechanism 8 is also connected to the impeller 55. The impeller 55 can adopt an existing structure, such as a centrifugal impeller. The driving mechanism 8 can be used not only to drive the grinding component 7, but also to drive the impeller 55. In this way, there is no need to set up a set of driving mechanisms 8 separately for the grinding component 7 and the impeller 55, and fewer parts are involved.

[0044] The pump housing 54 is a part of the housing 6, so that the water pump 5 and the food waste disposer are integrated together. In this embodiment, the grinding chamber 61 is located at the upper part of the housing 6, the pump housing 54 is the lower part of the housing 6, and the driving mechanism 8 includes a driving member 81 and an upper output shaft 82 and a lower output shaft 83 connected to the driving member 81. The driving member 81 is located between the grinding chamber 61 and the pump housing 54, the upper output shaft 82 is connected to the grinding assembly 7, and the lower output shaft 83 is connected to the impeller 55. The driving member 81 can be a motor.

[0045] Because the food waste disposer is usually connected to a sink, and the space below the sink is relatively ample, disposing the pump housing 54 below the grinding chamber 61 is equivalent to extending the length of the housing 6 in the longitudinal direction, thereby increasing the utilization rate of the space below the sink.

[0046] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
