[0029] Reference Figures 1 to 7 , which shows an embodiment of the cleaning device 100 provided by the utility model. The structure and working principle of the cleaning device 100 are described in detail below in conjunction with the drawings of the specification. The cleaning device 100 is applied to a range hood 200. The cleaning device 100 includes a conversion component 20 and a cleaning component 10; the conversion component 20 is provided with a first inlet 201 and a first outlet 202. The first inlet 201 is used to input a water source. The conversion component 20 is used to convert the water source into a cleaning medium and output it through the first outlet 202; the cleaning component 10 is arranged inside the range hood 200 and connected to the first outlet 202. The cleaning component 10 is provided with a cleaning portion 101 in communication with the first outlet 202 in both the horizontal and vertical directions. The cleaning portion 101 is used to release the cleaning medium.

[0030] In a specific implementation, a fan for extracting oil smoke is disposed on the inner side of the housing of the range hood 200. The fan is generally disposed at the center of the inner side of the range hood 200, and the fan is composed of a fan blade 2030 and a volute 2040 covered with a cover disposed outside the fan blade 2030. After the range hood 200 has been operated for a period of time, the inner side wall of the range hood 200 and the fan blade 2030, the volute 2040 and other parts of the fan are mostly dirty, so these parts are used as key dirt removal parts. In this embodiment, the cleaning device 100 is applied to the range hood 200 to clean the inner side of the range hood 200 so that the inner side of the range hood 200 is kept clean and sanitary. The cleaning device 100 is mainly composed of two parts, a conversion component 20 and a cleaning component 10. The conversion component 20 is provided with a first inlet 201 and a first outlet 202. The first inlet 201 is mainly used to input a water source, and the water source here can be tap water provided by a household faucet. The water source is input to the conversion component 20 through the first inlet 201, and the conversion component 20 can convert the input water source into a cleaning medium that can clean oil stains, such as steam, hot water and other media that can dissolve oil stains. After the conversion component 20 converts the input water source into a cleaning medium, the cleaning medium is output through the first outlet 202. The cleaning component 10 is disposed as a whole on the inner side of the range hood 200, and is mainly used to clean the parts of the inner side of the range hood 200 that are prone to oil stains, such as the volute 2040, the side wall and other parts of the range hood 200. The cleaning component 10 is connected to the first outlet 202 of the conversion component 20 to receive the cleaning medium output from the first outlet 202. The cleaning component 10 is provided with a cleaning part 101 in the horizontal direction and the vertical direction. The interior of the cleaning component 10 is a cavity. The cleaning part 101 is connected to the first inlet 201 through the cavity inside the cleaning component 10. The cleaning medium enters the cavity inside the cleaning component 10 through the first outlet 202. The cleaning medium input into the cleaning component 10 can be released through the cleaning part 101. The cleaning part 101 can specifically be a through hole or a nozzle or other structure. The method of releasing the cleaning medium specifically adopts a spraying method, that is, the cleaning medium is output from the first outlet 202 to the interior of the cleaning component 10 and then sprayed out by the cleaning part 101. The total number of cleaning sections 101 is multiple, and multiple cleaning sections 101 can release cleaning media at the same time. Since the cleaning sections 101 are arranged in the horizontal and vertical directions of the cleaning component 10, after the conversion component 20 converts the water source into a cleaning medium and outputs it to the cleaning component 10 through the first outlet 202, the cleaning section 101 in the horizontal direction of the cleaning component 10 releases the cleaning medium in the horizontal direction, and the cleaning section 101 in the vertical direction of the cleaning component 10 releases the cleaning medium in the vertical direction.The cleaning medium released in the horizontal direction can directly attach to the inner wall of the range hood 200 in the horizontal direction and the fan blades 2030 and the volute 2040 of the fan to play a cleaning role, while the cleaning medium released in the vertical direction can directly attach to the inner wall of the range hood 200 in the vertical direction and some other parts in the vertical direction to play a cleaning role. On the whole, the cleaning medium is released in both the horizontal and vertical directions to play a cleaning role, achieving all-round cleaning without dead angles. A waste oil cup 220 for collecting waste liquid is set at the bottom of the inner side of the range hood 200. The cleaning medium released by the cleaning part 101 on the cleaning component 10 decomposes the oil stains and mixes with the oil stains to form waste liquid. The waste liquid flows into the waste oil cup 220 under the action of gravity, and is finally discharged to the outside of the range hood 200 through the sewage pipe 210 set on the outside of the range hood 200.

[0031] The cleaning device provided in this embodiment converts a water source into a cleaning medium that can clean oil stains through a conversion component, the cleaning component is arranged on the inner side of the range hood, and a cleaning part for releasing the cleaning medium is arranged in the horizontal and vertical directions of the cleaning component. In cooperation with the conversion component, the cleaning part releases the cleaning medium in the horizontal and vertical directions of the inner side of the range hood at the same time, so that the cleaning medium can fully cover various dirt-hidden areas inside the range hood to play a cleaning role, thereby effectively improving the cleaning effect of the inside of the range hood.

[0032] In one embodiment, referring to Figure 2 and Figure 3The cleaning assembly 10 includes at least one first cleaning member 11 and at least one second cleaning member 12. The first cleaning member 11 and the second cleaning member 12 are both horizontally extended on the inner side wall of the range hood 200 in the horizontal direction, and the first cleaning member 11 and the second cleaning member 12 are perpendicular to each other. The cleaning portion 101 is arranged on the side walls of the first cleaning member 11 and the second cleaning member 12 in the horizontal and vertical directions. In a specific implementation, the first cleaning member 11 and the second cleaning member 12 are both columnar as a whole. The first cleaning member 11 and the second cleaning member 12 are both horizontally extended on the inner side wall of the range hood 200 in the horizontal direction, and the first cleaning member 11 and the second cleaning member 12 are perpendicular to each other in the horizontal direction, that is, the first cleaning member 11 is arranged on a side wall of the range hood 200 in the horizontal direction, and the second cleaning member 12 is arranged on another side wall of the range hood 200 in the horizontal direction, and the two remain perpendicular to each other. The lengths of the first cleaning member 11 and the second cleaning member 12 are adapted to the width of the inner side of the range hood 200 where the first cleaning member 11 and the second cleaning member 12 are located in the horizontal direction, and the cleaning parts 101 are arranged on the side walls of the first cleaning member 11 and the second cleaning member 12 in both the horizontal and vertical directions. Since the first cleaning member 11 and the second cleaning member 12 both have a side wall in the horizontal direction that needs to be connected and fixed to the inner side wall of the range hood 200, the cleaning parts 101 may not be arranged on the side of the first cleaning member 11 and the second cleaning member 12 that is connected to the side wall of the range hood 200 in the horizontal direction, and the cleaning parts 101 are arranged only on the side facing away from the inner side wall of the range hood 200 in the horizontal direction. The number of the first cleaning member 11 and the second cleaning member 12 is at least one, that is, one or more first cleaning members 11 and second cleaning members 12 can be provided. For example, two or more first cleaning members 11 or second cleaning members 12 can be provided at intervals on the inner side wall of the range hood 200 in the horizontal direction, or can be provided at intervals on the inner side wall of the range hood 200 in the horizontal direction. Through the first cleaning member 11 and the second cleaning member 12 arranged perpendicularly to each other, the cleaning unit 101 releases the cleaning medium in both the horizontal direction and the vertical direction of the first cleaning member 11 and the second cleaning member 12 at the same time, and the cleaning medium can be fully released and attached to the inner side wall of the range hood 200 in the horizontal, longitudinal and vertical directions, and at the same time, the cleaning medium is more fully attached to the fan blades 2030, the volute 2040 and other parts of the fan located at the inner center of the range hood 200, so as to achieve all-round cleaning of the inner side of the range hood 200 by the cleaning medium, thereby improving the cleaning effect.

[0033] Further, Figure 2 and Figure 3, there are two first cleaning members 11, which are arranged in parallel and at intervals on two inner side walls of the range hood 200 opposite to each other in the horizontal direction, and the second cleaning member 12 is arranged between the two first cleaning members 11. In a specific implementation, there are two first cleaning members 11, which are arranged in parallel and at intervals on two inner side walls of the range hood 200 opposite to each other in the horizontal direction, and the second cleaning member 12 is arranged between the two first cleaning members 11 and is kept perpendicular to the two first cleaning members 11, so that the cleaning portion 101 on the first cleaning member 11 and the cleaning portion 101 of the second cleaning member 12 are distributed in a "U" shape on the inner side of the range hood 200 as a whole. In cooperation with the conversion component 20, the cleaning portions 101 in the horizontal direction of the two first cleaning members 11 release the cleaning medium in the horizontal direction at the same time. The cleaning portion 101 in the horizontal direction of one of the first cleaning members 11 will release the cleaning medium toward the position of the other first cleaning member 11. On the whole, the cleaning portions 101 on the two first cleaning members 11 release the cleaning medium toward each other, and the cleaning portion 101 in the horizontal direction of the second cleaning member 12 is located between the two first cleaning members 11 and releases the cleaning medium in the horizontal direction, forming a large-scale release of the cleaning medium in the horizontal direction as a whole. The cleaning medium can be widely attached to the inner side wall of the range hood 200 in the horizontal direction and the fan blades 2030 and the volute 2040 of the fan in the center. At the same time, the cleaning portions 101 in the vertical direction of the first cleaning member 11 and the second cleaning member 12 release the cleaning medium in the vertical direction, which cleans the upper and lower inner side walls and the inner side walls in the horizontal direction of the range hood 200. On the whole, the cleaning effect of the range hood 200 is more comprehensive.

[0034] Furthermore, two second cleaning members 12 are provided, and the two second cleaning members 12 are arranged in parallel and at intervals between the two first cleaning members 11. In a specific implementation, on the basis that two first cleaning members 11 are provided, the number of second cleaning members 12 is also set to two, and the two second cleaning members 12 are arranged in parallel and at intervals between the two first cleaning members 11, and the two second cleaning members 12 are both kept perpendicular to the two first cleaning members 11, so that the two first cleaning members 11 and the two second cleaning members 12 are respectively located on two pairs of opposite inner side walls in the horizontal direction of the inner side of the range hood 200, and the two first cleaning members 11 and the two second cleaning members 12 together enclose an annular structure on the inner side of the range hood 200, so that the cleaning parts 101 on the two first cleaning members 11 and the cleaning parts 101 of the two second cleaning members 12 are distributed in an annular manner on the inner side of the range hood 200 as a whole. In cooperation with the conversion assembly 20, the cleaning parts 101 of the two first cleaning members 11 in the horizontal direction release the cleaning medium in the horizontal direction at the same time, and the cleaning part 101 of one of the first cleaning members 11 in the horizontal direction will release the cleaning medium toward the position where the other first cleaning member 11 is located; similarly, the cleaning parts 101 of the two second cleaning members 12 in the horizontal direction release the cleaning medium in the horizontal direction at the same time, and the cleaning part 101 of one of the second cleaning members 12 in the horizontal direction will release the cleaning medium toward the position where the other second cleaning member 12 is located. Overall, the cleaning parts 101 on the two first cleaning members 11 release the cleaning medium toward each other's position, and the cleaning parts 101 on the two second cleaning members 12 release the cleaning medium toward each other's position, so as to perform all-round cleaning on the inner side wall of the range hood 200 in the horizontal direction and the fan blades 2030 and the volute 2040 of the fan. At the same time, the cleaning parts 101 of the two first cleaning members 11 and the two second cleaning members 12 release cleaning media in the vertical direction, cleaning the upper and lower inner walls of the range hood 200 as well as the inner walls in the horizontal direction, so that the cleaning effect of the range hood 200 is more comprehensive as a whole.

[0035] In one embodiment, referring to Figure 4The conversion component 20 includes a steam generating unit 21 and a first boosting pump 22. The steam generating unit 21 is connected to the first inlet 201. The first boosting pump 22 is connected between the steam generating unit 21 and the first outlet 202. The steam generating unit 21 is used to heat the water source and convert it into water vapor. The first boosting pump 22 is used to pressurize and transport the water vapor to the first outlet 202. In a specific implementation, the conversion component 20 includes a steam generating unit 21 and a first boosting pump 22. The steam generating unit 21 is connected to the first inlet 201. The water source is input into the steam generating unit 21 from the first inlet 201. The steam generating unit 21 is a device that can heat the water source and convert it into water vapor. Here, the steam generating unit 21 is a steam generator. After the water source enters the steam generating unit 21, the water source is heated into water vapor under the action of the steam generating unit 21, and the water vapor is used as a cleaning medium. The first booster pump 22 is a device that can increase the pressure of the medium, and is connected between the steam generating unit 21 and the first outlet 202.

The water vapor pressurized by the first booster pump 22 is input into the cleaning component 10 from the first outlet 202. After the high-temperature and high-pressure water vapor enters the cleaning component 10, it is ejected at a certain speed through the cleaning part 101 in the horizontal and vertical directions of the cleaning component 10 under the action of pressure. The ejected high-temperature water vapor contacts the corresponding parts on the inner side of the range hood 200, so that the oil stains attached to the corresponding parts on the inner side of the range hood 200 are decomposed and dissolved, thereby achieving effective cleaning.

[0036] In one embodiment, referring to Figure 4The conversion component 20 includes a hot water generating unit 23 and a second booster pump 24. The hot water generating unit 23 is connected to the first inlet 201, and the second booster pump 24 is connected between the hot water generating unit 23 and the first outlet 202. The hot water generating unit 23 is used to heat the water source and convert it into hot water, and the second booster pump 24 is used to pressurize and transport the hot water to the first outlet 202. In a specific implementation, the conversion component 20 includes a hot water generating unit 23 and a second booster pump 24. The hot water generating unit 23 is connected to the first inlet 201. The water source is input into the hot water generating unit 23 from the first inlet 201. The hot water generating unit 23 is a device that can heat the water source into hot water. Its principle is the same as that of the water heater, which is electric heating. After the water source enters the hot water generating unit 23, the water source is heated into hot water under the action of the hot water generating unit 23, and the hot water is used as a cleaning medium. The second booster pump 24 is a device that can increase the pressure of the medium, and is connected between the hot water generating unit 23 and the first outlet 202. The hot water generated in the hot water generating unit 23 enters the second booster pump 24 for boosting. The hot water pressurized by the second booster pump 24 is input from the first outlet 202 to the cleaning component 10. After the high-temperature and high-pressure hot water enters the cleaning component 10, it is sprayed out at a certain speed through the cleaning part 101 in the horizontal and vertical directions of the cleaning component 10 under the action of pressure. The sprayed hot water contacts the corresponding parts on the inner side of the range hood 200. The high-temperature hot water decomposes and dissolves the oil stains attached to the corresponding parts on the inner side of the range hood 200, thereby achieving effective cleaning.

[0037] In one embodiment, referring to Figure 4The conversion component 20 includes a detergent supply unit 25 and a third booster pump 26, and the third booster pump 26 is connected between the detergent supply unit 25 and the first outlet 202, wherein the detergent supply unit 25 is used to contain detergent, and the third booster pump 26 is used to pressurize and deliver the detergent to the first outlet 202. In a specific implementation, the conversion component 20 includes the detergent supply unit 25 and the third booster pump 26, and the detergent supply unit 25 is a container as a whole, which is used to store and contain detergent, and the detergent is used as a cleaning medium. The detergent contained in the detergent supply unit 25 is usually a liquid detergent, such as detergent, washing spirit, etc. The third booster pump 26 is a device that can increase the pressure of the medium, and is connected between the detergent supply unit 25 and the first outlet 202. The detergent stored in the detergent supply unit 25 is pressurized by the third booster pump 26, and the pressurized detergent is input from the first outlet 202 into the cleaning component 10. Under the action of pressure, the detergent is sprayed out at a certain speed through the cleaning part 101 in the horizontal and vertical directions of the cleaning component 10, and the sprayed detergent contacts the corresponding parts on the inner side of the range hood 200. Since the detergent has an emulsifying effect on oil stains, the oil stains attached to the corresponding parts on the inner side of the range hood 200 are emulsified and decomposed, thereby achieving effective cleaning.

[0038] Furthermore, the conversion component 20 is also provided with a discharge port (not shown in the figure), and the discharge port 103 is connected to the detergent supply unit 25, and the discharge port 103 is used to put the detergent into the detergent supply unit 25. In a specific implementation, the detergent supply unit 25 is a container with a certain volume, and the detergent supply unit 25 can accommodate a limited amount of detergent. When the detergent in the detergent supply unit 25 is used up, it needs to be replenished in time. In this embodiment, a discharge port is provided on the conversion component 20, and the discharge port is connected to the inside of the detergent supply unit 25. It is mainly used to put detergent into the detergent supply unit 25. When the detergent in the detergent supply unit 25 is used up, the detergent can be very conveniently replenished into the detergent supply unit 25 through the discharge port, so that the amount of detergent in the detergent supply unit 25 can meet the cleaning use of the range hood 200.

[0039] In one embodiment, referring to Figures 5 to 7, the cleaning device 100 further includes a solenoid valve 30, the solenoid valve 30 is connected between the first inlet 201 and the water source, wherein the solenoid valve 30 is used to open or close the first inlet 201. In a specific implementation, the water source input conversion component 20 is controlled by the solenoid valve 30, and the solenoid valve 30 is connected between the first inlet 201 of the conversion component 20 and the water source. This embodiment takes a two-way solenoid valve 30 as an example, one port of the solenoid valve 30 is connected to the first inlet 201 of the conversion component 20, and the other port of the solenoid valve 30 is connected to the water source. The electromagnetic valve 30 realizes the communication and closing between the ports through electric control. When the electromagnetic valve 30 opens the first inlet 201, the water source can enter the conversion component 20 through the first inlet 201. When the electromagnetic valve 30 closes the first inlet 201, the water source cannot enter the conversion component 20 through the first inlet 201. By controlling the input of the water source through the electromagnetic valve 30, the quantitative injection of the water source into the conversion component 20 can be realized, that is, when the water source fills the conversion component 20, the input of the water source can be closed first, so that the quantitative water source is completely converted into the cleaning medium in the conversion component 20. The problem of incomplete conversion of the water source into the cleaning medium caused by continuous water source input can be avoided.
