[0047] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0048] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0050] The following is combined Figures 1 to 10The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.

[0051] Combination Figures 1 to 10 The present invention provides a cleaning assembly comprising a liquid storage component 100, a cleaning liquid container 200, and an output pump 500.

[0052] The liquid storage component 100 has an inlet end 110, a liquid outlet end 120 and an air outlet end 130. The liquid storage component 100 is installed inside the range hood, so that the user cannot see the liquid storage component 100, which improves the overall appearance of the range hood.

[0053] The cleaning fluid container 200 is connected to the inlet 110, which can provide the storage container 100 with the cleaning fluid that needs to be replenished, ensuring the normal operation of the cleaning components.

[0054] The output pump 300 has a liquid inlet 310, a foam outlet 320, and an air inlet 330. The liquid inlet 310 is connected to the liquid outlet 120 of the liquid storage device 100, which can extract the cleaning liquid in the liquid storage device 100. The air inlet 330 is connected to the air outlet 130 of the liquid storage device 100, which can draw in gas. After the gas drawn in by the output pump 300 is mixed with the extracted cleaning liquid, the liquid-gas mixture is output from the foam outlet 320 of the output pump 300, which can clean the range hood.

[0055] For example, foam outlet 320 can spray onto the volute of the range hood's duct system. The liquid-gas mixture can be dense foam, which flows onto the impeller of the duct system. The foam reacts fully with the grease on the impeller. At this time, the fan can rotate at a lower speed, throwing the mixture of foam and grease out of the impeller, flowing out from under the volute, and finally into the grease cup at the bottom of the range hood, completing the cleaning process.

[0056] It is understood that the cleaning assembly provided in the embodiments of this utility model includes a liquid storage device 100 having an inlet end 110, a liquid outlet end 120, and an air outlet end 130; an output pump 300 having a liquid inlet 310, a foam outlet 320, and an air inlet 330; and a cleaning liquid container 200 that can provide cleaning liquid to the liquid storage device 100; and the inlet end 110 is connected to the cleaning liquid container 200, the liquid inlet 310 is connected to the liquid outlet end 120, and the air inlet 330 is connected to... The outlet 130 allows the output pump 300 to draw cleaning fluid from the cleaning fluid container 200 into the storage container 100 to replenish the storage container 100. At the same time, the foam outlet 320 of the output pump 300 can also draw cleaning fluid from the storage container 100 and mix it with gas to output a liquid-gas mixture for cleaning the range hood. This cleaning component eliminates the need for two water pumps when cleaning the range hood, resulting in a simpler structure and cost savings.

[0057] Combination Figure 1 and Figure 3 To facilitate replenishment of the liquid storage unit 100, in some embodiments of this invention, the cleaning assembly further includes a replenishment pipe 400 and an air inlet 410. The air inlet 410 can be located on the smoke collection chamber side of the range hood. One end of the replenishment pipe 400 is connected to the cleaning liquid container 200, and the other end is detachably connected to the air inlet 410, which is connected to the inlet end 110 of the liquid storage unit 100. When the cleaning liquid in the liquid storage unit 100 is sufficient, the cleaning liquid container 200 can be easily removed to allow the output pump 300 to draw in air more fully.

[0058] Furthermore, in order to ensure that the output pump 300 can also fully draw in gas when the cleaning assembly replenishes the cleaning fluid to the liquid storage container 100, in some embodiments of this utility model, the flow rate of the air inlet 330 is greater than the flow rate of the liquid inlet 310; at this time, the liquid in the liquid storage box is also continuously drawn into the pump for mixing, and the liquid in the liquid storage box is continuously increasing, and the liquid in the liquid storage box is replenished after 30 to 120 seconds.

[0059] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the cleaning assembly further includes a nozzle assembly 500. The input end of the nozzle assembly 500 is connected to the foam outlet 320 of the output pump 300, and the output end of the nozzle assembly 500 faces the area of ​​the range hood that needs to be cleaned. When the output pump 300 sprays a mixture of cleaning liquid and air, it can be sprayed from the nozzle assembly onto the range hood for cleaning, which can improve the cleaning degree and expand the cleaning range.

[0060] Specifically, in some embodiments of this utility model, the nozzle assembly 500 includes a nozzle 510, a nozzle pipe 520, and a nozzle support 530.

[0061] The nozzle 520 connects the foam outlet 320 of the output pump 300 to the nozzle 510, so that the liquid-gas mixture of the output pump 300 can be delivered to the nozzle 510 through the nozzle 520. The nozzle bracket 530 fixes the nozzle 510 on the volute of the range hood, making the nozzle 510 more stable during cleaning and preventing it from being displaced by the backlash force of the cleaning.

[0062] The nozzle 510 is equipped with spray holes that face the impeller blades of the range hood, making it easy to precisely clean the areas of the range hood that need cleaning.

[0063] To improve the intelligence level of the cleaning component and make the cleaning operation simpler, more convenient and faster, in some embodiments of this utility model, the cleaning component further includes a first liquid level sensor 600 and a second liquid level sensor 610.

[0064] The first liquid level sensor 600 is located above the liquid storage container 100 and can detect the liquid level at the top of the liquid storage container 100 to prevent the cleaning liquid from overflowing and ensure the cleaning and safety of the range hood.

[0065] The second liquid level sensor 610 is located below the liquid storage container 100. It can detect the liquid level at the bottom of the liquid storage container 100 and provide feedback to the user to replenish the cleaning fluid in time, so as to avoid stopping the cleaning work due to insufficient cleaning fluid in the liquid storage container 100.

[0066] When the user activates the cleaning function of the range hood, the first liquid level sensor 600 and the second liquid level sensor 610 detect signals. When the liquid volume V in the storage container is greater than 0, the output pump 300 and the range hood motor start working. The output pump 300 simultaneously draws in gas and liquid from the storage container 100. The liquid enters the output pump 300 through the liquid outlet 120 of the storage container 100; the gas enters the space above the liquid surface in the storage container 100 through the air inlet 410 and enters the output pump through the air outlet 130 of the storage container 100. After the gas and liquid mix in the output pump 300, they are converted into gas-liquid foam, which can finally be sprayed out from the nozzle 510 to clean the range hood.

[0067] When the liquid volume V in the reservoir 100 is less than or equal to V0, the second liquid level sensor 610 will send feedback to the range hood system, which will then remind the user to replenish the liquid. The user can connect one end of the replenishment pipe 400 to the air inlet 410 and the other end to the cleaning liquid container 200 containing the cleaning solvent. After activating the range hood's cleaning function, the output pump 300 starts working. Due to the negative pressure generated at the air inlet 330 of the output pump 300, the cleaning solvent in the cleaning liquid container 200 is drawn into the reservoir 100. Simultaneously, the liquid in the reservoir 100 is continuously drawn into the output pump 300 and mixed. Because the flow rate at the air inlet 330 of the output pump 300 is much greater than the flow rate at the liquid inlet 310, the liquid in the reservoir 100 will continuously increase, and the liquid in the reservoir 100 can be completely replenished after 30–120 seconds (e.g., 60 seconds, where 's' is seconds). At this time, the range hood's program will continue to run a complete cleaning cycle. After this cleaning function is completed, no additional liquid replenishment is required when the cleaning function is started next time, allowing the solvent to remain in the range hood for an extended period.

[0068] Combination Figure 7 and Figure 8 In order to ensure that the liquid in the liquid storage component 100 can be fully utilized and extracted, reducing the frequency of liquid replenishment, in some embodiments of this utility model, the liquid storage component 100 is a water storage box 700, which includes a water storage box shell 710, a support plate 720, and a water extraction pipe 730.

[0069] The support plate 720 is fixed to the side panel inside the range hood, and the water storage box housing 710 is mounted on the support plate 720.

[0070] The first end of the water pumping pipe 730 extends into the bottom of the water storage box housing 710, and the second end of the water pumping pipe 730 is connected to the liquid outlet 120.

[0071] An embodiment of this utility model also provides a range hood, which includes the above-mentioned cleaning component and range hood body 800, and the liquid storage component 100 of the cleaning component is disposed in the range hood body 800.

[0072] It is understood that the range hood provided in the embodiments of this utility model, since it includes the aforementioned cleaning components, inevitably possesses all the advantages of those components. That is, the range hood no longer requires two water pumps for cleaning, resulting in a simpler structure and cost savings.

[0073] Furthermore, in some embodiments of this utility model, the cleaning liquid container 200 of the cleaning component is disposed outside the range hood body 800 and is detachably connected to the range hood body 800, which makes it easier to install or remove the cleaning liquid container 200 and improves the liquid replenishment efficiency of the range hood.
