[0041] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] Range hoods, as a common kitchen appliance, are widely used in kitchens to quickly remove and exhaust cooking fumes outdoors. During operation, grease and grime adhere to the inside of the range hood, and over time, this can cause grease and grime to drip from the internal walls onto the stovetop or clog the grease filter, thus affecting the range hood's performance. Therefore, regular cleaning of the range hood's interior is necessary. Currently, cleaning range hoods mainly relies on manual labor, which is time-consuming, laborious, and results in a poor user experience. Some range hoods have automatic cleaning devices, but these devices often have insufficient water flow and can only spray one type of cleaning agent, leading to poor cleaning effectiveness inside the range hood.

[0043] To address the aforementioned technical problems, this application provides a range hood that can select a suitable cleaning method based on the degree of grease buildup inside the hood, automatically cleaning the interior to avoid the time-consuming and laborious nature of manual cleaning, improve cleaning effectiveness, and thus enhance the user experience. The specific details of the range hood are further described below with reference to the accompanying drawings.

[0044] Figure 1 A structural schematic diagram of the range hood 100 is shown. Figure 2 It shows Figure 1 Another structural diagram from the perspective of Figure 3 It shows Figure 1 A schematic diagram of the structure of the spray component 120. Figure 4 It shows Figure 3 A cross-sectional schematic diagram. Combined with... Figures 1-4The range hood 100 includes a body 100, a spray component 120, and a filler component 130. The spray component 120 is connected inside the body 100 and has multiple spray holes 121. The filler component 130 is disposed inside the spray component 120, and the filler component 130 and the spray component 120 form a spray cavity 124. The filler component 130 has an independent first cavity 131 and a second cavity 132 inside, and both the first cavity 131 and the second cavity 132 are connected to the spray cavity 124.

[0045] The range hood 100 provided in this application has a spray component 120 connected inside the body 100. The spray component 120 has multiple spray holes 121, and a filler 130 is disposed inside the spray component 120. The filler 130 and the spray component 120 form a spray cavity 124. Therefore, the volume of the spray cavity 124 can be reduced, and the spray speed of the cleaning consumables sprayed from the spray holes 121 can be increased, thereby improving the cleaning effect on the inner wall of the body 100. In addition, since the filler 130 has an independent first cavity 131 and a second cavity 132, the first cavity 131... Both the first and second cavities 131 and 132 are connected to the spray chamber 124. Therefore, depending on the degree of oil contamination inside the machine body 100, one type of cleaning consumable can be delivered to the first cavity 131 or the second cavity 132, and one type of cleaning consumable can be sprayed from the spray hole 121 to adapt to cleaning scenarios with low oil contamination levels; or, one type of cleaning consumable can be delivered to the first cavity 131 and another type of cleaning consumable can be delivered to the second cavity 132, so that the spray hole 121 can spray two types of cleaning consumables to improve the cleaning effect inside the machine body 100 to adapt to cleaning scenarios with high oil contamination levels.

[0046] Combination Figure 1 as well as Figure 2 There are two spray elements 120, which are respectively located at the two top corners inside the body 100 so that the two spray elements 120 are arranged opposite each other. In addition, the range hood 100 also includes a fan 140, which is disposed inside the body 100. The fan 140 is provided with an air inlet 141, that is, the fan 140 has an air inlet side. Two spray members 120 are disposed opposite to the air inlet side of the fan 140. Each of the two spray members 120 has a first spray surface 122 facing the air inlet 141 of the fan 140. The first spray surface 122 is provided with spray holes 121. Cleaning consumables can be sprayed through the spray holes 121 of the first spray surface 122 onto the back panel of the body 100 and the air inlet side of the fan 140 to clean the back panel of the body 100 and the air inlet side of the fan 140. In addition, cleaning consumables can also enter the interior of the fan 140 through the air inlet 141 of the fan 140 to clean the interior of the fan 140.

[0047] Combination Figure 1 as well as Figure 2The two spray elements 120 also have opposing second spray surfaces 123, each with spray holes 121. Cleaning consumables are sprayed through the spray holes 121 of the second spray surfaces 123 onto the side walls of the machine body 100 to clean the side walls of the machine body 100. Of course, in other embodiments, other sides of the spray elements 120 may also be provided with spray holes 121, depending on the cleaning requirements. This application does not impose any restrictions on this.

[0048] Combination Figure 1 as well as Figure 2 In one embodiment, the spray component 120 can be a right-angled trapezoid. When the spray component 120 is assembled into the body 100, one of its base edges is attached to the inner top of the body 100, and the right-angled edge is attached to the inner side of the side of the body 100, thereby connecting the two sides of the spray component 120 to the body 100 and improving the reliability of the spray component 120 assembly. Additionally, the lower base of the spray component 120 is attached to the inner top of the body 100, meaning the upper base of the spray component 120 is located below its lower base. Therefore, the spray component 120 is an inverted right-angled trapezoid. In another embodiment, the spray component 120 can also be other polygonal structures, such as a right triangle. Preferably, the polygonal structure also has two perpendicular sides to facilitate the assembly of the spray component 120 within the body 100.

[0049] Combination Figure 1 as well as Figure 2 The distance between the second spray surfaces 123 of the two spray components 120 decreases from bottom to top, meaning the second spray surfaces 123 are inclined. Since the spray components 120 are assembled in a slightly upper position inside the body 100, the inclined second spray surfaces 123 allow cleaning consumables to be sprayed not only on the sides of the body 100 but also to the bottom inside the body 100, thus thoroughly cleaning the body 100 and improving the cleaning effect.

[0050] Combination Figure 3 as well as Figure 4The spray nozzles 120 have multiple spray holes 121 arranged in an array, which allows the cleaning consumables to be sprayed evenly, achieving comprehensive cleaning of the inner cavity of the machine body 100. They also form sound-absorbing holes to reduce noise during operation of the range hood to a certain extent. In one embodiment, the diameter of the spray holes 121 increases progressively from top to bottom along the height direction of the machine body 100. The diameter of the spray holes 121 can be increased in stages; for example, the diameter of the upper spray holes 121 (e.g., the spray hole 121 opposite the first cavity 131) is slightly smaller, while the diameter of the lower spray holes 121 (e.g., the spray hole 121 opposite the second cavity 132) is slightly larger. This enhances the atomization effect of the cleaning consumables sprayed by the upper spray holes 121 and increases the spray flow rate of the cleaning consumables sprayed by the lower spray holes 121, achieving a better cleaning effect. In other embodiments, the diameter of the spray holes 121 can remain the same, and this application does not impose any limitations on this.

[0051] Combination Figure 3 and Figure 4 The shape of the filler 130 is adapted to the spray member 120, that is, the filler 130 and the spray member 120 have similar shapes. When the filler 130 is assembled into the spray member 120, the spray cavity 124 formed between the spray member 120 and the filler 130 is only located in at least a portion of the periphery of the filler 130, so that the spray cavity 124 forms a slit, further reducing the internal space of the spray cavity 124 and further increasing the spraying speed of the cleaning consumables. Specifically, the filler 130 and the first spray surface 122 and the second spray surface 123 of the spray member 120 have gaps, and the filler 130 abuts against the remaining sides of the spray member 120 to minimize the spray cavity 124 and increase the spraying speed of the cleaning consumables. In other embodiments, the filler 130 and the remaining sides of the spray member 120 may also have gaps, which is not limited in this application.

[0052] Combination Figure 3 as well as Figure 4The range hood 100 also includes a first partition 133, a first connector 151, and a second connector 152. The first partition 133 is disposed inside the filler 130 and divides the filler 130 into independent first cavities 131 and second cavities 132. The water inlet ends of the first connector 151 and the second connector 152 are both located outside the spray member 120. The first connector 151 passes through the first cavity 131, and the second connector 152 passes through the second cavity 132. The water outlet ends of the first connector 151 and the second connector 152 are both connected to the spray chamber 124. The first connector 151 and the second connector 152 respectively deliver different types of cleaning consumables. Since the first connector 151 and the second connector 152 are directly connected to the spray chamber 124, this arrangement allows the cleaning consumables to be delivered directly to the spray chamber 124 without having to pass through the first chamber 131 or the second chamber 132. Since the spray chamber 124 is a slit, the spraying speed of the cleaning consumables can be increased, thus improving the cleaning effect.

[0053] Figure 5 It shows Figure 4 A frontal view diagram. Combined with... Figure 5 In one embodiment, the partition extends further to the spray chamber 124, dividing the spray chamber 124 into a first spray chamber 1241 and a second spray chamber 1242. The first spray chamber 1241 is connected to the water outlet of the first connector 151, and the cleaning consumables delivered by the first connector 151 are output through the spray holes 121 of the first spray chamber 1241. The second spray chamber 1242 is connected to the water outlet of the second connector 152, and another type of cleaning consumable delivered by the second connector 152 is sprayed out through the spray holes 121 of the first spray chamber 1241. That is, the two types of cleaning consumables are sprayed out independently. For example, the first spray chamber 1241 is located above the second spray chamber 1242, and the cleaning consumables sprayed out by the first spray chamber 1241 are cleaning agents, while the consumables sprayed out by the second spray chamber 1242 are cleaning water.

[0054] In another embodiment, the aforementioned partition may be omitted, meaning the spray chamber 124 is a single, integral cavity. The cleaning consumables delivered by the first connector 151 are output through the spray holes 121 of the spray chamber 124, and another type of cleaning consumables delivered by the second connector 152 are sprayed out through the spray holes 121 of the spray chamber 124. In specific implementation, the delivery sequence of the cleaning consumables can be controlled according to the selected cleaning mode, allowing different cleaning consumables to be sprayed out through the spray holes 121. For example, one type of cleaning water and detergent can be sprayed out first, followed by the other type, allowing the cleaning water and detergent to be sprayed out intermittently; or, the first connector 151 delivers one type of cleaning consumable, and the second connector 152 delivers another type, both types of cleaning consumables are simultaneously delivered to the spray chamber 124, and after mixing within the spray chamber 124, the mixed cleaning consumables are output through the spray holes 121.

[0055] Combination Figure 1 as well as Figure 2 The water inlet end of the first connector 151 and the water inlet end of the second connector 152 both pass through the top of the body 100 to facilitate the connection of the first connector 151 and the second connector 152 with the pipe. The water outlet end of the first connector 151 and the water outlet end of the second connector 152 can both be in the form of a 90° bend. The water outlet end of the first connector 151 and the water outlet end of the second connector 152 both face the fan 140 inside the body 100, that is, the water outlet end of the first connector 151 and the water outlet end of the second connector 152 both face the first spray surface 122.

[0056] Combination Figure 1 The range hood 100 also includes a heater 160, which can be arranged in the middle of the top of the body 100. The heater 160 is disposed between two spray elements 120 and communicates with the spray chamber 124 of the spray element 120 to deliver heated cleaning consumables to the spray chamber 124 of the spray element 120. Specifically, the heater 160 communicates with the spray chamber 124 of the spray element 120 through at least one of the first connector 151 and the second connector 152 to deliver at least one heated cleaning consumable to the spray chamber 124 of the spray element 120.

[0057] Figure 6 A schematic diagram of the delivery of cleaning consumables in one embodiment is shown. (Combined with...) Figure 2 as well as Figure 6 The range hood 100 also includes a housing 170, which contains a third cavity 171 and a fourth cavity 172. The third cavity 171 stores one type of cleaning consumable, and the fourth cavity 172 stores another type of cleaning consumable. At least one of the third cavity 171 and the fourth cavity 172 is connected to a heater 160, so that the heater 160 can heat at least one type of cleaning consumable and deliver it to the spray chamber 124, thereby allowing the heated cleaning consumable to be sprayed out through the spray hole 121, thereby improving the cleaning effect.

[0058] Combination Figure 6In one embodiment, the third chamber 171 is used to store clean water, and the fourth chamber 172 is used to store cleaning consumables such as detergent. The heater 160 has a built-in pump body. The input end of the heater 160 is connected to the third chamber 171, and the heater 160 has two output ends, which are respectively connected to the first connectors 151 of the two spray elements 120. The range hood 100 also includes a washing pump 180. The input end of the washing pump 180 is connected to the fourth chamber 172, and the washing pump 180 also has two output ends, which are respectively connected to the second connectors 152 of the two spray elements 120. When cleaning the inside of the machine body 100, the clean water can be heated by the heater 160 to generate steam. After the steam is sprayed out from the spray holes 121 of the spray elements 120, it can soften the grease on the inner wall of the machine body 100. Cleaning consumables such as detergent are directly pumped to the spray elements 120 by the washing pump 180 to decompose the grease.

[0059] Figure 7 A schematic diagram of the delivery of cleaning consumables in another embodiment is shown. (Combined with...) Figure 7 In another embodiment, two heaters 160 may be provided, one of which is connected to the third cavity 171 and the other is connected to the fourth cavity 172. That is, both water and detergent can be heated, and the heated water and detergent are used to clean the inner wall of the machine body 100 to further improve the cleaning effect inside the machine body 100.

[0060] Figure 8 A structural schematic diagram of the housing 170 is shown. Figure 9 It shows Figure 8 A schematic diagram of the explosion. Combined with... Figure 8 as well as Figure 9 To facilitate the replacement of the housing 170, the housing 170 is detachably mounted on the outside of the body 100, for example, on the front side of the body 100. A second partition 173 is provided inside the housing 170, arranged vertically to divide the interior of the housing 170 into the aforementioned third cavity 171 and fourth cavity 172. An openable door 174 is provided on the top of the housing 170. After the housing 170 is removed from the body 100, the door 174 is opened to add clean water and / or the spray unit 120 into the housing 170.

[0061] Figure 10 This diagram shows the assembly of the housing 170 onto the body 100. Figure 11 It shows Figure 10 The explosion diagram, combined with 8- Figure 11The side of the body 100 is provided with two third connectors 111, each with a built-in valve. One of the third connectors 111 is connected to the heater 160 via a pipe, and the other third connector 111 is connected to the washing pump 180 via a pipe. The side of the housing 170 is provided with two fourth connectors 175, which are configured one-to-one with the third connectors 111. One of the fourth connectors 175 is connected to the third cavity 171, and the other fourth connector 175 is connected to the fourth cavity 172. When the housing 170 is assembled onto the body 100, the fourth connector 175 is inserted into the corresponding third connector 111, and the valve in the corresponding third connector 111 is opened at the same time, so that the third cavity 171 is connected to the heater 160, and the clean water in the third cavity 171 can be delivered to the heater 160. The fourth cavity 172 is connected to the washing pump 180, and the detergent in the fourth cavity 172 can be pumped to the spray unit 120 by the washing pump 180.

[0062] After the user assembles the housing 170 into place, when activating the cleaning function of the range hood 100, there are three cleaning modes:

[0063] The first cleaning mode: First, start the washing pump 180. The detergent in the fourth chamber 172 of the housing 170 is pumped into the spray chamber 124 of the spray component 120 and sprayed out from the spray hole 121 to decompose the oil stains in the machine body 100. During the decomposition of oil stains, the fan 140 can be controlled to jog or rotate continuously at low speed. Then, start the heater 160. The clean water in the third chamber 171 of the housing 170 is heated into steam and then transported into the spray chamber 124 of the spray component 120 and sprayed out from the spray hole 121 to rinse the decomposed oil stains. During the rinsing process, the fan 140 jogs or rotates continuously at low speed, and can also pump detergent in intermittently or continuously for a period of time. Finally, the machine is dried by the high-speed fan 140.

[0064] The second cleaning mode: First, the heater 160 is activated, and the clean water in the third chamber 171 of the housing 170 is heated into steam and then transported to the spray chamber 124 of the spray element 120 and sprayed out from the spray hole 121 to soften the oil stains; then the washing pump 180 is activated, and the detergent in the fourth chamber 172 of the housing 170 is pumped into the spray chamber 124 of the spray element 120 and sprayed out from the spray hole 121 to decompose the oil stains in the machine body 100. During the decomposition of oil stains, the fan 140 can be controlled to jog or rotate continuously at low speed; then the heater 160 is activated again, and the clean water in the third chamber 171 of the housing 170 is heated into steam and then transported to the spray chamber 124 of the spray element 120 to rinse the decomposed oil stains. During the rinsing process, the fan 140 jogs or rotates continuously at low speed, and detergent can also be pumped in intermittently or continuously for a period of time. Finally, the oil is dried by the high-speed fan 140. Compared to the first cleaning mode, the second cleaning mode softens the grease with steam first, which improves the detergent's ability to break down grease. Therefore, the second cleaning mode is suitable for cleaning scenarios with higher grease concentrations within 100ml of the machine body.

[0065] The third cleaning mode: First, the heater 160 and the washing pump 180 are started simultaneously. The clean water in the third chamber 171 is heated into steam and then delivered to the spray chamber 124 of the spray unit 120. The detergent in the fourth chamber 172 of the housing 170 is pumped into the spray chamber 124 of the spray unit 120. The clean water and detergent in the spray chamber 124 mix and are sprayed out from the spray hole 121, forming a mixed cleaning. The heater 160 is started again, and the decomposed oil stains are rinsed by steam. During the rinsing process, the fan 140 rotates intermittently or continuously at a low speed, and can also pump detergent in intermittently or continuously for a period of time. Finally, the final steam rinsing and air drying are carried out by the high-speed fan 140. Compared with the second cleaning mode, the third cleaning mode improves the decomposition effect of detergent on oil stains because it softens and decomposes oil stains by mixing steam and detergent. Therefore, the third cleaning mode is more suitable for cleaning scenarios with higher oil stain concentrations inside the machine body 100.

[0066] As described above, the range hood 100 provided in this application can select different cleaning modes to clean the inner wall of the machine body 100 according to the degree of oil stains inside the machine body 100, which can save consumables to a certain extent and has good practicality. It should be noted that different cleaning modes can be selected by the user. For example, the cleaning mode option can be set on the operation panel of the range hood 100 or the control terminal connected to the range hood 100, and the user can actively select the cleaning mode; or / and, the range hood 100 is equipped with an oil fume concentration detector, which can obtain the oil fume concentration inside the machine body 100. When the user needs to clean the inside of the machine body 100, the controller of the range hood 100 automatically selects a cleaning mode that matches the oil fume concentration based on the obtained oil fume concentration inside the machine body 100. This disclosure does not limit this.
