A spray inner tube is vertically arranged between the spray rod and the spray pipe, and the spray rod is movably sleeved on the spray inner tube. A lifting mechanism is also provided on the spray rod, which drives the spray rod to rise and fall.

[0004] Among the existing technologies, including the aforementioned patents, most self-cleaning ovens can effectively clean the inside of the oven. The bottom of most self-cleaning ovens typically has a horizontally placed tray with a filter rack fixed to it. Cleaning water is then circulated to clean the oven walls. However, in actual use, some impurities remaining on the horizontally placed tray sometimes cannot be effectively rinsed into the filter rack. Furthermore, existing single-layer filter racks are prone to clogging, leading to difficulties in subsequent water drainage. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning oven that can improve the cleaning effect of the bottom tray inside the oven and reduce the problem of filter clogging.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a self-cleaning oven, comprising a self-cleaning oven body and a heating cavity and a liquid collection cavity disposed therein and interconnected therewith. The bottom of the heating cavity is provided with an inclined portion, and a filter assembly is provided on the inner wall of the heating cavity at the lower position of the inclined portion. The filter assembly includes a ring and a receiving rack and a fine mesh rack arranged vertically inside the ring, with the receiving rack located above the fine mesh rack. A liquid collection box is inserted into the liquid collection cavity.

[0007] Preferably, a spray nozzle is fixedly installed on the top of the self-cleaning oven body, and a water pump connected to the spray nozzle is fixedly installed in the self-cleaning oven body, with the first end of the water inlet pipe fixedly connected to the water pump located on one side of the liquid collection box.

[0008] Preferably, a rubber hose is inserted into the first end of the water inlet pipe, and a filter screen is fixedly installed at the end of the rubber hose.

[0009] Preferably, the bottom of the collection box is provided with an inclined bottom, and the rubber hose is located above the high position of the inclined bottom, while the ring is located above the low position of the inclined bottom.

[0010] Preferably, the inclined bottom is provided with multiple slag collection troughs, and a shielding part is provided on one side of the slag collection troughs on the inclined bottom.

[0011] Preferably, the fine mesh frame is a stainless steel mesh frame.

[0012] In the above technical solution, the self-cleaning oven provided by this utility model has the following beneficial effects: by setting the ring at the low position of the inclined part, when cleaning is sprayed inside the self-cleaning oven, the residue on the inclined part will move to the low position of the inclined part along with the water flow, thereby reducing the residue remaining on the inclined part. At the same time, the receiving rack is used to intercept large food residue particles, and then the fine mesh rack is used to intercept fine food residue particles, thereby avoiding the problem of filter mesh clogging caused by food residue accumulating on a filter screen. Then the filtered water flows into the collection box for collection. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, a self-cleaning oven includes a self-cleaning oven body 1 and a heating cavity 11 and a liquid collection cavity 12 disposed therein and connected to each other. The bottom of the heating cavity 11 is provided with an inclined part 13, and a filter assembly is provided on the inner wall of the heating cavity 11 at the lower position of the inclined part 13. The filter assembly includes a ring 4 and a receiving rack 41 and a fine mesh rack 42 arranged vertically inside the ring 4, with the receiving rack 41 located above the fine mesh rack 42. A liquid collection box 2 is inserted into the liquid collection cavity 12. By positioning the ring 4 at the lower position of the inclined section 13, when cleaning is sprayed inside the self-cleaning oven body 1, the residue on the inclined section 13 will move towards the lower position of the inclined section 13 along with the water flow, thereby reducing the residue remaining on the inclined section 13. At the same time, the receiving rack 41 is used to intercept large food residue particles, and then the fine mesh rack 42 is used to intercept fine food residue particles, thereby avoiding the problem of food residue accumulating on a filter screen and causing filter screen clogging. Then the filtered water flows into the collection box 2 for collection.

[0022] As a further technical solution provided by this utility model, a nozzle 3 is fixedly installed on the top of the self-cleaning oven body 1, and a water pump 31 connected to the nozzle 3 is fixedly installed inside the self-cleaning oven body 1. The first end of the water inlet pipe 32 fixedly connected to the water pump 31 is located on one side of the liquid collection box 2.

[0023] Specifically, such as Figure 2 and Figure 3 As shown, the water inlet pipe 32 is connected to the water inlet end of the water pump 31, and the nozzle 3 is connected to the water outlet end of the water pump 31. The water pump 31 is used to draw the filtered cleaning liquid in the collection box 2, and the nozzle 3 is used to spray it again into the heating chamber 11 to achieve cyclic cleaning.

[0024] Furthermore, a rubber hose 33 is inserted into the first end of the water inlet pipe 32, and a filter screen package 34 is fixedly installed at the end of the rubber hose 33.

[0025] Specifically, the cleaning fluid entering the rubber hose 33 is filtered again by using the filter screen package 34. The filter screen package 34 can be made of an extremely fine filter screen and a fixing frame to wrap around the end of the rubber hose 33. The rubber hose 33 can be inserted into the water inlet pipe 32 for subsequent disassembly and cleaning. When the self-cleaning oven body 1 is pulled out of the liquid collection box 2, the rubber hose 33 deforms to detach from the liquid collection box 2.

[0026] Furthermore, the bottom of the liquid collection box 2 is provided with an inclined bottom 21, and the rubber hose 33 is located above the high position of the inclined bottom 21, while the ring 4 is located above the low position of the inclined bottom 21.

[0027] Specifically, after the liquid and food residue in the grilling chamber 11 are filtered by the receiving rack 41 and fine mesh rack 42 on the ring 4, some of the food residue and liquid flow down into the liquid collection box 2. Then, the liquid carries the food residue from the low position to the high position of the inclined bottom 21, while some of the food residue will be deposited at the bottom of the liquid collection box 2. As the inclined bottom 21 moves from the low position to the high position, it creates a certain resistance to the food residue, so that the food residue is better retained in the liquid collection box 2.

[0028] Furthermore, multiple slag collection troughs 22 are provided on the inclined bottom 21, and a shielding part 23 is provided on one side of the slag collection troughs 22 on the inclined bottom 21.

[0029] Specifically, when some food residue moves from the lower to the higher position of the inclined bottom 21, the multiple residue collection troughs 22 and the blocking parts 23 on the inclined bottom 21 cause some food residue to settle in the residue collection troughs 22, and create resistance to the food residue moving towards the higher position of the inclined bottom 21, such as... Figure 4 As shown, by using the inclined state of the inclined bottom 21 itself, in conjunction with the slag collection tank 22 and the shielding part 23, the deposited food residue is better collected in the liquid collection box 2, reducing the problem of being sucked into the water pump 31 and clogging the nozzle 3.

[0030] Furthermore, the fine mesh frame 42 is a stainless steel mesh frame.

[0031] Working principle: The water pump 31 draws the cleaning liquid from the collection box 2 and sprays it into the grilling chamber 11 through the nozzle 3 for cleaning. The residue on the inclined part 13 moves to the lower part of the inclined part 13 with the water flow, thereby reducing the residue remaining on the inclined part 13. At the same time, the receiving rack 41 intercepts large food residue particles, and then the fine mesh rack 42 intercepts fine food residue particles, thereby avoiding the problem of food residue accumulating on a filter screen and causing filter screen clogging. The filtered water then flows into the collection box 2 for collection. Then, the liquid carrying food residue moves from the lower to the higher position of the inclined bottom 21. Some of the food residue will settle at the bottom of the collection box 2. As the inclined bottom 21 moves from the lower to the higher position, it creates a certain resistance to the food residue. At the same time, through the multiple slag collection grooves 22 and the shielding part 23 on the inclined bottom 21, some food residue is deposited in the slag collection grooves 22, and further resistance is created to the food residue moving towards the higher position of the inclined bottom 21. This makes the deposited food residue better collected in the collection box 2, reducing the problem of being sucked into the nozzle 3 by the water pump 31 and clogging the nozzle 3.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
