[0035] ]>The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0036] Next, refer to the attached Figures 1 to 8 to describe the range hood according to an embodiment of the present invention.

[0037] As Figures 1 to 8 shown, the range hood according to an embodiment of the present invention includes: a range hood body 1, an oil mesh 2, a flap 3, and a cleaning component 4. An air inlet 11 is provided on the range hood body 1. The oil mesh 2 is arranged at the air inlet 11. The flap 3 is connected to the range hood body 1. The flap 3 is movable between a first position for opening the air inlet 11 and a second position for closing the air inlet 11. The cleaning component 4 is connected to the range hood body 1. The cleaning component 4 is movable relative to the oil mesh 2 to clean the oil stains on the oil mesh 2.

[0038] The range hood according to an embodiment of the present invention can move the flap 3 between a first position and a second position to open and close the air inlet 11, thereby improving the use effect of the range hood. In addition, since the cleaning component 4 can move relative to the oil mesh 2, the oil stain on the oil mesh 2 can be cleaned by the cleaning component 4, so that the oil mesh 2 does not need to be removed, making the oil stain cleaning of the range hood convenient, with a simple structure and good cleaning effect.

[0039] In some embodiments, there is one air inlet 11, and the single air inlet 11 is provided on the front surface of the range hood body 1 and extends along the length direction of the range hood body 1 (such as Figure 4 the left - right direction). By setting the air inlet 11 to be one, the range hood according to the embodiment of the present invention can reduce the number of components in the range hood body 1, facilitate assembly, has a simple structure, and good practicability.

[0040] In other embodiments, as Figure 1 and Figure 2 shown, there are two air inlets 11, and the two air inlets 11 are provided on the front surface of the range hood body 1 and are arranged at intervals along the length direction of the range hood body 1 (such as Figure 4 the left - right direction). It can be understood that an oil mesh 2 is provided at each air inlet 11, and a cleaning component 4 is provided on each oil mesh 2. The user can open one or two air inlets 11 according to actual needs, which is convenient for the user to use and can improve the oil extraction effect of the range hood.

[0041] In some embodiments, the cleaning component 4 may not be in direct contact with the oil mesh 2. For example, the cleaning component 4 may be a hot air blower, which is opposite to the oil mesh 2, and the hot air blower can spray hot air flow to melt the oil stain on the oil mesh 2. The cleaning component 4 can move relative to the oil mesh 2 so that the hot air blower can clean different positions of the oil mesh 2, thereby making the cleaning effect of the cleaning component 4 better.

[0042] In other embodiments, as Figure 3 and Figure 5 shown, the cleaning component 4 is in direct contact with the oil mesh 2. For example, the cleaning component 4 includes a scraper 41, and the scraper 41 is movable relative to the oil mesh 2 and abuts against the oil mesh 2. The range hood according to the embodiment of the present invention can scrape the oil stain on the oil mesh 2 through the scraper 41, so that the structure of the cleaning component 4 of the range hood is simple, the cost is low, and the cleaning effect is good.

[0043] Optionally, the scraper 41 is made of an elastic material. For example, the scraper 41 is made of silica gel material. By setting the scraper 41 to be made of an elastic material, the range hood according to the embodiment of the present invention can avoid the scraper 41 scratching the oil mesh 2, improve the service life of the scraper 41 and the oil mesh 2, and can make the cleaning effect of the oil stain better.

[0044] Specifically, asFigure 3 and Figure 5 As shown in Figure 5 , the cleaning assembly 4 further includes a first driving member 43. The first driving member 43 is disposed on the main body 1 of the range hood and is connected to the scraper 41. The first driving member 43 is used to drive the scraper 41 to move relative to the oil net 2. In the range hood according to the embodiment of the present invention, the first driving member 43 drives the scraper 41 to translate relative to the oil net 2, so that the cleaning assembly 4 can automatically clean the oil net 2, thereby improving the automation degree of the range hood, having higher reliability, and being convenient for users to use. For example, the first driving member 43 is one of a linear motor, a cylinder, and an oil cylinder. By setting the first driving member 43 to the above structure in the range hood according to the embodiment of the present invention, the structure of the range hood can be simplified, and the production cost of the range hood can be reduced.

[0045] Optionally, as Figure 3 and Figure 5 shown, the first driving member 43 is detachably connected to the scraper 41. In the range hood according to the embodiment of the present invention, by detachably connecting the scraper 41 to the first driving member 43, the assembly and disassembly of the scraper 41 can be facilitated. When the scraper 41 is damaged or aged, the scraper 41 can be replaced, thereby improving the cleaning effect of the range hood and having better practicability.

[0046] Specifically, as Figure 6 shown, the cleaning assembly 4 further includes a fixing seat 42. The fixing seat 42 is connected to the first driving member 43. One of the fixing seat 42 and the scraper 41 is provided with a clamping groove 421, and the other is provided with a clamping protrusion 411. The clamping protrusion 411 is clamped in the clamping groove 421. For example, the fixing seat 42 is provided with the clamping groove 421, and the scraper 41 is provided with the clamping protrusion 411. Optionally, the inner end of the clamping groove 421 is provided with an arc groove with a circular cross section, and one end of the clamping protrusion 411 facing away from the oil net 2 is provided with a convex column with a circular cross section. The convex column cooperates with the arc groove. It can be understood that when installing the scraper 41, the clamping protrusion 411 can be inserted into the clamping groove 421 from the side of the fixing seat 42. Due to the setting of the arc groove and the convex column, the scraper 41 can be prevented from moving in the direction close to or away from the oil net 2, thereby improving the reliability of the scraper 41 when cleaning oil stains. In addition, in the range hood according to the embodiment of the present invention, by clamping the fixing seat 42 to the scraper 41, the installation and disassembly of the scraper 41 are facilitated, and the structural design is simple, and the processing and manufacturing difficulty is low.

[0047] In some embodiments, as Figure 6As shown, a heating element 6 is provided on at least one of the scraping plate 41 and the oil screen 2. It can be understood that the heating element 6 can be provided alone on the scraping plate 41, or alone on the oil screen 2, or heating elements 6 are provided on both the scraping plate 41 and the oil screen 2. In the embodiment of the range hood of the present invention, heating elements 6 are provided on the scraping plate 41 and the oil screen 2, so that the oil stain can be heated by the heating element 6 to soften the oil stain, thereby facilitating the scraping plate 41 to clean the oil stain on the oil screen 2 and making the cleaning effect of the oil screen 2 better.

[0048] Optionally, as Figure 6 shown, the heating element 6 includes a first heating element 61, and the first heating element 61 is arranged inside the scraping plate 41. Specifically, the heating element 6 can be arranged on the surface of the scraping plate 41 or inside the scraping plate 41. For example, the first heating element 61 is a heating wire, and the heating wire penetrates into the scraping plate 41 along the length direction of the scraping plate 41. There is a certain distance between the first heating element 61 and the free end of the scraping plate 41, so that it will neither affect the oil scraping effect of the scraping plate 41 nor can heat the scraping plate 41, thereby making the cleaning effect of the scraping plate 41 on the oil screen 2 better.

[0049] Optionally, the heating element 6 further includes a second heating element (not shown), and the second heating element is wound around the oil screen 2. For example, the second heating element can be a heating net or a heating wire, and the second heating element can cover the oil screen 2. The first heating element 61 and the second heating element can be heated simultaneously to further accelerate the dissolution rate of the oil stain on the oil screen 2 and make the cleaning effect of the oil screen 2 better.

[0050] In some embodiments, as Figure 3 and Figure 5 shown, a first oil baffle 31 is provided on the side of the flap 3 adjacent to the oil screen 2. The range hood body 1 includes a panel 12, and the lower end of the oil screen 2 is connected to the panel 12. In the second position, the first oil baffle 31 abuts against the panel 12. By providing the first oil baffle 31 in the embodiment of the range hood of the present invention, it is possible to prevent the oil stain on the oil screen 2 from flowing out of the range hood body 1 and make the use effect of the range hood better. It can be understood that the oil stain scraped off from the oil screen 2 can be guided through the channel formed between the first oil baffle 31, the oil screen 2 and the panel 12, so that the oil stain can be smoothly introduced into the oil cup and the oil stain cleaning effect of the range hood is better.

[0051] Optionally, as Figure 7 and Figure 8As shown, the oil screen 2 is provided with oil holes 21, and the oil holes 21 extend along the movement direction of the scraper 41. It can be understood that when the scraper 41 moves up and down, the oil holes 21 extend in the up and down direction. When the scraper 41 moves left and right, the oil holes 21 extend in the left and right direction. On the side of the scraper 41 adjacent to the oil screen 2, there are oil scraping teeth 412. For example, there are multiple oil scraping teeth 412, and the multiple oil scraping teeth are arranged along the length direction of the scraper 41. The range hood of the embodiment of the present invention can scrape the oil stains around the oil holes 21 through the oil scraping teeth 412, so that the scraper 41 can scrape the oil stains on the oil screen 2 more cleanly, and further improve the cleaning effect of the range hood.

[0052] Optionally, the surfaces of the oil screen 2 and the scraper 41 can be sprayed with an oil-repellent coating. For example, the oil-repellent coating can be a nano-coating and a Teflon coating, so as to reduce the adhesion of oil stains and make the oil stain cleaning effect of the range hood better.
