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

[0026] This application discloses an integrated stove.

[0027] Reference Figure 1 An integrated stove includes an air duct assembly 1, a washing assembly 2, and an oil collection box 3. The air duct assembly 1 includes a volute 11 and an impeller 12. The washing assembly 2 includes a power unit 21 and a spray unit 22. The oil collection box 3 can be used to collect grease and store cleaning fluid. When the impeller 12 needs to be cleaned, the cleaning fluid is stored in the oil collection box 3. The power unit 21 can spray the cleaning fluid from the spray unit 22 into the volute 11. The volute 11 is provided with a volute liquid guide port 110 for guiding the liquid in the volute 11 into the oil collection box 3, so that the cleaning fluid in the oil collection box 3 can be recycled, thereby making full use of the space and structure of the oil collection box 3 itself, without being limited by the space constraints of the overall structure of the integrated stove.

[0028] In this embodiment, refer to Figure 1 and Figure 2 The spray section 22 is a spray nozzle connected to the volute 11. A spray hole 220 communicating with the inner cavity of the volute 11 is provided in the portion of the spray nozzle located inside the volute 11. The spray hole 220 faces the blades of the impeller 12. An inlet 221 is provided in the portion of the spray nozzle located outside the volute 11. A spray chamber is provided inside the spray nozzle. Both the inlet 221 and the spray hole 220 are connected to the spray chamber. A delivery pipe 222 for delivering cleaning fluid is provided between the inlet 221 and the power unit 21. The power unit 21 delivers the cleaning fluid from the oil collection box 3 to the spray chamber through the delivery pipe 222, enabling the cleaning fluid sprayed from the spray hole 220 to clean the blades of the impeller 12. Multiple spray holes 220 can be provided. The central axis directions of the multiple spray holes 220 can be the same or different, or partially the same and partially different, thereby enabling cleaning of more parts of the impeller 12 blades.

[0029] Reference Figure 3 Multiple injection holes 220 are provided, and the centers of at least multiple injection holes 220 are connected to form at least one first axis. The first axis is set at an angle to the extension direction of the blade tip of the impeller 12.

[0030] In other embodiments, a delivery pipe 222 may be provided between the spray unit 22 and the power unit 21, and the cleaning fluid may be delivered into the volute simply by means of the spray hole 220, without washing the blades of the impeller 12. The purpose is to clean the blades by accumulating a certain level of cleaning fluid inside the volute 11.

[0031] To enable the recycling of the cleaning fluid, the volute 11 is provided with a volute liquid guide port 110 for guiding the liquid inside the volute 11 into the oil collection box 3. The volute liquid guide port 110 is located at or near the lowest point of the volute 11. In this embodiment, the air duct assembly 1 also includes a bellows 13 located outside the volute 11. The bellows 13 surrounds the outside of the volute 11. A bellows liquid guide port 130 is provided at the bottom of the bellows 13. The volute liquid guide port 110 is higher than the bellows liquid guide port 130. The bottom wall inside the bellows 13 is inclined around the bellows liquid guide port 130. The bellows liquid guide port 130 is located at the lowest point, so that the grease or cleaning fluid flowing out of the volute liquid guide port 110 can flow into the oil collection box 3 through the bellows liquid guide port 130. The structure of the oil collection box 3 is the same as that of a conventional integrated stove. The oil collection box 3 is located below the air box 13, and has a rectangular, open-top structure. The air box liquid guide port 130 is aligned with the upper opening of the oil collection box 3, and the oil collection box 3 is slidably connected to the integrated stove body near the bottom. The oil collection box 3 can slide and be pulled out of the integrated stove body, allowing for the pouring out of grease or the addition and replacement of cleaning fluid. Figure 5The inner wall of the oil collection box 3 is provided with a water level indicator line 31, which includes a maximum water level line and a minimum water level line. The maximum water level line is higher than the minimum water level line. When the liquid in the oil collection box 3 is between the maximum water level line and the minimum water level line, it indicates that the amount of cleaning fluid can achieve the best cleaning effect.

[0032] Refer to Figure 4 and Figure 5 The power unit 21 is provided with an inlet 210 for connecting to the oil collection box 3 and an outlet 2120 for connecting to the delivery pipe 222. The power unit 21 includes an oil collection part 211 and a power pump 212. The oil collection part 211 is provided with an oil collection chamber 2110 that communicates with the inlet 210 and the outlet 2120. One of the oil collection part 211 and the power pump 212 is provided with an inlet 210 and the other is provided with an outlet 2120.

[0033] In this embodiment, the liquid collection section 211 is provided with a liquid inlet 210, and the power pump 212 is provided with a liquid outlet 2120.

[0034] The liquid collection section 211 can be configured as a cylinder, cuboid, or other three-dimensional structure according to the actual space of the integrated stove. The liquid collection section 211 can also be a pipe connected to the power pump 212, with the liquid inlet 210 located at the end of the pipe away from the power pump 212.

[0035] A heating element 5 for heating the liquid in the collection chamber 2110 is provided at the bottom of the liquid collection section 211. The heating element 5 can be an electric heating plate. The heating part of the heating element 5 is located inside the collection chamber 2110, and the energized part of the heating element 5 is located at the bottom outside the liquid collection section 211. The energized part can be used to turn the heating element 5 on and off, thereby heating or stopping the heating of the cleaning fluid in the collection chamber 2110. The liquid collection section 211 is provided with a temperature sensor 51, which is electrically connected to a controller. The controller is electrically connected to the heating element 5 and controls the on and off of the heating element 5 according to the temperature signal transmitted by the temperature sensor 51. When the temperature reaches the set value or range, the controller controls the heating element 5 to turn off the power. When the temperature does not reach the set value or range, the controller controls the heating element 5 to turn on the power and heat the liquid in the collection chamber 2110.

[0036] Combination Figure 6 and Figure 7 The outer peripheral wall of the liquid collecting part 211 is connected to the docking part 213. The docking part 213 is provided with a flow channel cavity that communicates with the liquid collecting chamber 2110. The end of the flow channel cavity away from the liquid collecting part 211 is formed as an inlet 210 that penetrates the docking part 213. The inlet 210 is used to communicate with the liquid inlet 30 of the oil collecting box 3, so that the cleaning liquid in the oil collecting box 3 can enter the liquid collecting chamber 2110.

[0037] The power pump 212 is provided with a connecting part 214, which is fixed to the outer peripheral wall of the liquid collecting part 211. The connecting part 214 is provided with a power chamber that communicates with the liquid collecting chamber 2110. The liquid outlet 2120 is provided at the connecting part 214. The power pump 212 can be a vacuum pump to generate negative pressure in the power chamber, thereby enabling the cleaning liquid in the liquid collecting chamber 2110 to be pumped out from the liquid outlet 2120.

[0038] In other embodiments, the inlet 210 can be provided on the power pump 212 and communicate with the liquid inlet 30 of the oil collection box 3, and the outlet 2120 can be provided on the liquid collection part 211 so that the liquid collection chamber 2110 communicates with the inner cavity of the delivery pipe 222.

[0039] Reference Figure 8 The liquid collection section 211 is provided with a drain port 61 communicating with the liquid collection chamber 2110. A drain control component for opening and closing the drain port 61 is provided at the drain port 61. The drain control component includes a fixed part 62, a movable part 63 movably connected to the fixed part 62, and a first sealing part 64 connected to the movable part 63 and moving with the movable part 63 to achieve sealing or detachment from the drain port 61. When circulation cleaning is required, cleaning fluid is put into the liquid collection chamber 2110, and the drain port 61 is closed by using the drain control component. The cleaning fluid in the liquid collection chamber 2110 is pumped out through the outlet 2120 by the power pump 212. After cleaning is completed, the drain port 61 is opened by using the drain control component, so that the sewage in the liquid collection chamber 2110 can be discharged. The fixed part 62 includes two parallel guide rods, the movable part 63 is slidably connected to the two guide rods, and the first sealing part 64 is connected to the movable part 63 on the side facing the drain outlet 61. The movable part 63 is driven to move in the direction toward or away from the drain outlet 61 by a power member fixed on the fixed part 62, thereby achieving the sealing or detachment of the first sealing part 64 and the drain outlet 61.

[0040] To facilitate the connection between the liquid inlet 30 of the oil collection box 3 and the liquid inlet 210 of the power unit 21, an opening and closing assembly 4 is provided between the liquid inlet 210 and the liquid inlet 30. This assembly opens or closes the liquid inlet 30 as the oil collection box 3 moves. The opening and closing assembly 4 includes a part connected to the oil collection box 3 and another part connected to the power unit 21. When the oil collection box 3 is fully slid into the body of the integrated stove and the two parts of the opening and closing assembly 4 are in contact, the liquid inlet 210 and the liquid inlet 30 remain connected. When the oil collection box 3 slides out of the body of the integrated stove, the two parts of the opening and closing assembly 4 separate and close the liquid inlet 30, allowing the oil collection box 3 to store cleaning fluid. When the oil collection box 3 slides into the body of the integrated stove but the two parts of the opening and closing assembly 4 are not in contact, the liquid inlet 30 also remains closed, allowing the oil collection box 3 to normally receive the grease flowing out of the volute 11.

[0041] Reference Figure 6 and Figure 7 The opening and closing assembly 4 includes a guide sleeve 41, a guide rod 42 located inside the guide sleeve 41 for sealing with the liquid inlet 30, a push rod 43 for pushing the guide rod 42 to move, and an elastic element 44 for resetting the guide rod 42. The power unit 21 is connected to the push rod 43. The oil collection box 3 is provided with the guide rod 42 and the guide sleeve 41. The push rod 43 is used to extend into the guide sleeve 41 and apply force to the guide rod 42 to disengage the guide rod 42 from the liquid inlet 30 to achieve communication between the liquid inlet 210 and the liquid outlet 30. The elastic element 44 is used to seal the guide rod 42 with the liquid outlet 30 without other external force. In this embodiment, the guide rod 42 is rod-shaped, with one part extending into the oil collection box 3 and the other part extending out of the liquid inlet 30 and located in the guide sleeve 41. The push rod 43 is connected to the power unit 21. When the guide rod 42 moves with the oil collection box 3 and is moved by the push rod 43, the guide rod 42 and the liquid inlet 30 are separated, so that the liquid in the oil collection box 3 can flow through the liquid inlet 30 into the guide sleeve 41 and flow to the liquid inlet 210. When the push rod 43 does not apply force to the guide rod 42, the elastic force of the elastic member 44 can keep the guide rod 42 and the liquid inlet 30 sealed, so that the liquid in the oil collection box 3 will not flow out through the liquid inlet 30.

[0042] In other embodiments, the guide rod 42 can be completely disposed within the oil collection box 3, or completely disposed within the guide sleeve 41 outside the oil collection box 3. When the guide rod 42 is subjected to the force of the push rod 43 during the movement of the oil collection box 3, the guide rod 42 can not be limited to sliding along a straight line; it can also rotate. The push rod 43 drives the guide rod 42 to rotate during the movement of the oil collection box 3, thereby achieving communication or sealing between the guide rod 42 and the liquid inlet 30. For example, the rotation axis of the guide rod 42 is in the middle of the guide rod 42, one end of the guide rod 42 is subjected to the force of the push rod 43, and the other end is used to seal the liquid inlet 30. The elastic element 44 is used to keep the guide rod 42 sealed to the liquid inlet 30 without other external forces. The guide rod 42 and the push rod 43 are not limited to being rod-shaped; the guide rod 42 can be a disc or a piston.

[0043] In other embodiments, the opening and closing assembly 4 may also include a valve provided at the liquid inlet 30, the valve having an opening and closing switch, and an actuating element provided on the power unit 21. The switch may be mechanical or electronic. When the switch contacts the actuating element, the valve may be kept open. When the switch does not contact the actuating element, the valve may be kept closed.

[0044] In this embodiment, the guide rod 42 includes a second sealing portion 421 for sealingly mating with the inner wall of the liquid passage port 30 and a guiding portion 422 connected to the second sealing portion 421. The second sealing portion 421 is located inside the oil collecting box 3 and is cylindrical. The guiding portion 422 is located inside the guide sleeve 41. The guide sleeve 41 is connected to the outer wall of the oil collecting box 3 and surrounds the liquid passage port 30. The guiding portion 422 is slidably connected to the inside of the guide sleeve 41. A sealing ring for sealingly mating with the peripheral wall of the liquid passage port 30 is embedded on the end face of the second sealing portion 421 facing the liquid passage port 30. A part of the size of the guiding portion 422 is smaller than the size of the liquid passage port 30, so that when the second sealing portion 421 disengages from the liquid passage port 30, the liquid in the oil collecting box 3 can flow out from the liquid passage port 30. The size of the end of the guiding portion 422 far from the second sealing portion 421 is similar to the size of the inner wall of the guide sleeve 41, so that the outer peripheral wall of the end of the guiding portion 422 far from the second sealing portion 421 fits with the inner peripheral wall inside the guide sleeve 41. And the elastic member 44 can be selected as a spring. The elastic member 44 is sleeved outside the guiding portion 422, and one end is connected to the side of the guiding portion 422 far from the second sealing portion 421, and the other end is connected inside the guide sleeve 41.

[0045] The ejector rod 43 is connected to the docking portion 213. The docking portion 213 extends along the central axis of the liquid inlet 210 at the end of the liquid inlet 210 to form a limiting sleeve 45 located outside the guide sleeve 41. A sealing ring is provided outside the guide sleeve 41. When the ejector rod 43 extends into the guide sleeve 41, the guide sleeve 41 also extends into the limiting sleeve 45, so that the outer peripheral wall of the guide sleeve 41 and the inner peripheral wall of the limiting sleeve 45 are kept sealed.

[0046] The ejector rod 43 is arranged around the liquid inlet 210. The ejector rod 43 can be annular, and a through hole communicating with the liquid inlet 210 is provided at the center of the ejector rod 43. The ejector rod 43 can also be a structure with an arc-shaped or semi-circular cross-section. The ejector rod 43 can also be a structure with a cross-section approximately in the shape of a Chinese character 'Ri'. The ejector rod 43 only needs to have a solid surface that can abut against the guide rod 42. In order to maintain the stability of the connection between the liquid passage port 30 and the liquid inlet 210 when the ejector rod 43 pushes the guide rod 42 to disengage from the liquid passage port 30, at this time, the elastic member 44 is compressed, and the rebounding force exerted by the elastic member 44 on the guide rod 42 is less than the frictional force between the components of the opening and closing assembly 4, that is, the force for the elastic member 44 to restore its original state can be close to the frictional force between the guide sleeve 41 and the limiting sleeve 45 and between the guide sleeve 41 and the ejector rod 43, so that the connection relationship between the liquid passage port 30 and the liquid inlet 210 can be maintained during the cleaning process.

[0047] The implementation principle of this embodiment is as follows: When the oil collection box 3 is fully slid into the integrated stove body and the top rod 43 pushes the guide rod 42 to slide into the oil collection box 3, the liquid inlet 30 is opened, and the liquid inlet 210 and the liquid inlet 30 remain in communication, allowing the cleaning fluid in the oil collection box 3 to flow into the liquid inlet 210. When the oil collection box 3 slides out of the integrated stove body, the top rod 43 disengages from the guide rod 42. Under the action of the elastic element 44, the second sealing part 421 and the liquid inlet 30 remain sealed, closing the liquid inlet 30 so that the oil collection box 3 can store the cleaning fluid. When the oil collection box 3 slides into the integrated stove body but the top rod 43 has not yet pushed the guide rod 42, the liquid inlet 30 remains closed, allowing the oil collection box 3 to normally receive the grease flowing out of the volute 11. The power unit 21 can use the cleaning fluid in the liquid collection unit 211 to enter the spray unit 22 through the delivery pipe 222, and spray it towards the blades of the impeller 12 through the spray hole 220. The cleaning fluid is rinsed and enters the air box 13 through the volute liquid guide port 110, and flows back to the oil collection box 3 through the air box liquid guide port 130, thereby realizing the circulation cleaning.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
