[0039] Reference Figures 1 to 6 In one embodiment of the utility model, a range hood is provided, which includes a housing 100, an air duct cover and a partition 300. The housing 100 is provided with a cavity, and a first smoke inlet 111 and a second smoke inlet 121 connected to the cavity are provided on the front side wall of the housing 100, and the first smoke inlet 111 and the second smoke inlet 121 are arranged at intervals along the length direction of the housing 100. The air duct cover is provided above the housing 100 and connected to the cavity, and a fan 210 is installed in the air duct cover. The partition 300 is provided in the cavity and divides the cavity into a first smoke collecting chamber 110 and a second smoke collecting chamber 120 connected to the first smoke inlet 111 and the second smoke inlet 121 in a one-to-one correspondence, and the first smoke collecting chamber 110 and the second smoke collecting chamber 120 are both connected to the air duct cover. Among them, a protective groove 310 is provided on the rear side of the partition 300.

[0040] By adopting the range hood of the embodiment of the utility model, the cavity is divided into a first smoke inlet cavity and a second smoke inlet cavity corresponding to the first smoke inlet 111 and the second smoke inlet 121 by using the partition 300, so that the smoke flowing in from the first smoke inlet 111 can flow to the air duct cover through the first smoke collecting cavity 110, and the smoke flowing in from the second smoke inlet 121 can flow to the air duct cover through the second smoke collecting cavity 120, that is, the smoke at the two smoke inlets can flow into the corresponding smoke collecting cavity without interfering with each other, that is, the smoke flowing in from the two smoke inlets is not easy to cause air flow turbulence due to cross collision during the flow process, thereby improving the flow rate of the smoke in the cavity, and then improving the smoking efficiency. In addition, by setting a protective groove 310 on the rear side of the partition 300, some parts in the smoke collecting cavity can be installed in the protective groove 310, so that these parts can be shielded and protected, the smoke in the cavity can be resisted, and the pollution and corrosion caused by the smoke to these parts are reduced, and the surface of these parts is also made cleaner, reducing the difficulty of cleaning.

[0041] Reference Figures 1 to 6In some embodiments, the protection groove 310 is an open groove opened on the rear side of the partition 300 , and the rear side wall of the housing 100 abuts against the rear side of the partition 300 and blocks the rear opening of the protection groove 310 .

[0042] In the above structure, by setting the protection groove 310 as an open groove located on the rear side of the partition 300, it is easy to open the protection groove 310, and by abutting the rear side of the partition 300 against the rear side wall of the housing 100, the rear opening of the protection groove 310 can be blocked by the rear side wall of the housing 100, thereby further protecting and limiting the parts in the protection groove 310, thereby improving the protection effect of the protection groove 310. In addition, this structure is also conducive to the installation of parts in the protection groove 310. Specifically, the parts can be installed inside the cavity first, and then the partition 300 can be installed, so that the protection groove 310 is covered on the periphery of the parts and abuts against the rear side wall of the housing 100.

[0043] Reference Figures 1 to 6 In some embodiments, the protection groove 310 extends in the up-down direction and passes through the upper end surface and the lower end surface of the partition 300 , and the protection groove 310 is formed by bending the left and right side edges of the partition 300 backwards.

[0044] By adopting the above structure, the protection groove 310 is extended in the up-down direction and penetrates the upper end surface and the lower end surface of the partition 300, so that the protection groove 310 can be easily opened and the connection between the parts in the protection groove 310 and the external structure can be easily made. The protection groove 310 is formed by bending the left and right side edges of the partition 300 backwards, which not only improves the structural strength of the partition 300, but also makes the processing of the protection groove 310 simpler and more convenient, and only needs to be bent, which is conducive to improving the production and processing efficiency of the partition 300.

[0045] Reference Figures 1 to 7 An oil guide pipe 140 is provided in the protection groove 310 , the upper end of the oil guide pipe 140 extends toward the fan 210 and can receive oil drops on the surface of the fan 210 , and the lower end of the oil guide pipe 140 extends to the bottom of the cavity.

[0046] By adopting the above structure, the upper end of the oil guide pipe 140 extends close to the fan 210, and the lower end extends to the oil cup 400, so that the oil droplets accumulated on the outer surface of the fan 210 can be received and guided to the bottom of the cavity, so as to prevent the oil droplets from directly dripping onto the inner wall of the housing 100 or dripping downward from the smoke inlet onto the stove after accumulating on the outer surface of the fan 210, thereby making the range hood cleaner, thereby reducing the difficulty of cleaning the housing 100, and also making the stove environment cleaner and tidier. By arranging the oil guide pipe 140 in the protective groove 310, the pollution and corrosion of the oil smoke in the cavity to the oil guide pipe 140 can be reduced, which not only prolongs the service life of the oil guide pipe 140, but also makes the surface of the oil guide pipe 140 cleaner, thereby making the removal, replacement, and maintenance of the oil guide pipe 140 more convenient, and reducing the difficulty of cleaning the oil guide pipe 140.

[0047] Reference Figures 1 to 10 In some embodiments, the housing 100 is further provided with a third smoke collecting chamber 130 located above the cavity and extending forward relative to the cavity, the third smoke collecting chamber 130 is connected to the first smoke collecting chamber 110 and the second smoke collecting chamber 120, the air duct cover is located above the third smoke collecting chamber 130 and is connected to the third smoke collecting chamber 130, and the lower side wall of the third smoke collecting chamber 130 is provided with a third smoke inlet 131. As a result, the range hood can also extract oil smoke through the third smoke inlet 131 above, further improving the efficiency of oil smoke extraction. At this time, the fan 210 is located above the third smoke collecting chamber 130, and by providing the oil guide pipe 140, it can further prevent the oil droplets accumulated on the outer surface of the fan 210 from dripping directly from the third smoke inlet 131 onto the stove.

[0048] Reference Figures 1 to 10 A water pipe 150 is passed through the protection groove 310 , one end of the water pipe 150 extends upward close to the fan 210 and is connected to a nozzle 151 for cleaning the fan 210 , and the other end of the water pipe 150 extends to the outside of the casing 100 .

[0049] By adopting the above structure, the water pipe 150 can guide the external clean water to the nozzle 151, and clean the fan 210 through the nozzle 151, thereby preventing the fan 210 from accumulating a large amount of oil and dirt and affecting the smoke extraction effect of the fan 210, thereby improving the oil smoke extraction efficiency of the range hood. By inserting the water pipe 150 into the protective groove 310, the pollution and corrosion of the oil smoke in the cavity to the water pipe 150 can be reduced, which can not only extend the service life of the water pipe 150, but also make the surface of the water pipe 150 cleaner, thereby making the removal, replacement and maintenance of the water pipe 150 more convenient, and reducing the difficulty of cleaning the water pipe 150.

[0050] It is understandable that, referring to Figures 6 to 10In some embodiments, the fan 210 includes a volute 211 and a wind wheel 212. The volute 211 is installed in the air duct cover, and the wind wheel 212 is installed in the volute 211. The nozzle 151 is specifically installed in the volute 211, and the water inlet end of the nozzle 151 is located outside the volute 211, and the water outlet end of the nozzle 151 extends to the inside of the volute 211, thereby facilitating the cleaning of the inner wall of the volute 211 and the wind wheel 212 in the volute 211, thereby making it easier to clean the fan 210, further reducing the impact of accumulated oil on the operation of the fan 210, and helping to improve the oil fume extraction efficiency of the range hood.

[0051] It is understandable that, referring to Figure 1 and Fig.10 In some embodiments, the water pipe 150 and the oil guide pipe 140 are installed in the protection groove 310 at the same time, thereby protecting the water pipe 150 and the oil guide pipe 140 at the same time, and improving the space utilization rate in the cavity, making the structure of the range hood more compact. Of course, in addition to this, only the water pipe 150 can be installed in the protection groove 310, or only the oil guide pipe 140 can be installed in the protection groove 310 as needed, and the present invention does not make specific limitations on this.

[0052] Reference Figures 1 to 10 In some embodiments, an oil guide pipe 140 is provided in the protection groove 310 , and an upper edge of the oil guide pipe 140 has a receiving portion 141 extending outward from bottom to top toward the fan 210 .

[0053] In the above structure, the setting of the receiving portion 141 can receive and collect the oil droplets accumulated on the surface of the fan 210 to a greater extent, and guide the collected oil smoke into the oil guide pipe 140, and guide it to the bottom of the cavity through the oil guide pipe 140, further reducing the risk of some oil droplets on the surface of the fan 210 directly avoiding the oil guide pipe 140 and dripping downward onto the side wall of the cavity or the stove.

[0054] Reference Figures 1 to 10 In some embodiments, the protective groove 310 is penetrated by an oil guide pipe 140 and a water pipe 150, and also includes a water cup 500 and an oil cup 400. Both the water cup 500 and the oil cup 400 can be detachably installed at the bottom of the casing 100. Both the oil guide pipe 140 and the water pipe 150 are penetrated by the bottom wall of the casing 100 and extend to the bottom of the casing 100.

[0055] By adopting the above structure, when the range hood is in normal use, the oil cup 400 can be installed at the bottom of the housing 100, so that the oil guide pipe 140 can directly guide the oil droplets accumulated on the surface of the fan 210 into the oil cup 400. When the fan 210 needs to be cleaned or the oil stains in the oil cup 400 need to be cleaned, the oil cup 400 can be removed from the housing 100. If the fan 210 needs to be cleaned, the water cup 500 can be installed at the bottom of the housing 100, and the lower end of the water pipe 150 is connected to the water cup 500, so that the water in the water cup 500 can be pumped to the nozzle 151 through the water pipe 150 by a water pump to clean the fan 210, which is convenient for users to operate and use.

[0056] It is understandable that the oil cup 400 and the water cup 500 can be detachably mounted on the bottom of the housing 100 by means of snap connection or screw connection.

[0057] Reference Figures 6 to 10 In some embodiments, a mounting member 160 is installed on the bottom wall of the casing 100, and the mounting member 160 has a first mounting hole 161 and a second mounting hole 162 extending through the bottom wall of the casing 100, the lower end of the oil guide pipe 140 is connected to the first mounting hole 161, and the lower end of the water pipe 150 is connected to the second mounting hole 162.

[0058] In the above structure, the installation of the mounting member 160 is conducive to extending the water pipe 150 and the oil guide pipe 140 to the bottom of the housing 100, thereby facilitating the oil guide pipe 140 to guide the oil droplets into the oil cup 400, and also facilitating the extraction of clean water in the water cup 500 into the water pipe 150. In addition, the installation of the mounting member 160 is also conducive to fixing the water pipe 150 and the oil guide pipe 140, so that the installation of the water pipe 150 and the oil guide pipe 140 is more firm and stable.

[0059] It can be understood that the lower end of the oil guide tube 140 is connected to the first mounting hole 161. Specifically, the lower end of the oil guide tube 140 and the first mounting hole 161 can be plugged into each other, thereby making the connection between the oil guide tube 140 and the connecting piece more secure, thereby facilitating the fixing of the oil guide tube 140, making the installation of the oil guide tube 140 more secure and stable. Similarly, the lower end of the water pipe 150 is connected to the second mounting hole 162. Specifically, the lower end of the water pipe 150 and the second mounting hole 162 can be plugged into each other, thereby making the connection between the water pipe 150 and the connecting piece more secure, thereby facilitating the fixing of the water pipe 150, making the installation of the water pipe 150 more secure and stable.

[0060] Reference Figures 8 to 10In some embodiments, the water cup 500 has a clean water tank 510 and a dirty water tank 520 . When the water cup 500 is installed on the housing 100 , the first mounting hole 161 is connected to the dirty water tank 520 , and the second mounting hole 162 is connected to the clean water tank 510 .

[0061] By adopting the above structure, when it is necessary to clean the fan 210, the water cup 500 is installed at the bottom of the housing 100, and clean water is placed in the clean water tank 510. The lower end of the water pipe 150 is connected to the clean water tank 510, so that the water pipe 150 can pump the clean water in the clean water tank 510 to the nozzle 151 through the water pump, so as to clean the fan 210. The sewage formed after cleaning the fan 210 can drip into the oil guide pipe 140 along the outer surface of the fan 210, and flow along the oil guide pipe 140 to the sewage tank 520 of the water cup 500. This process is conducive to discharging the sewage generated by cleaning the fan 210 to the outside of the housing 100, and avoiding the accumulation of sewage inside the housing 100. In addition, when cleaning the fan 210 , the sewage flowing into the oil guide pipe 140 can also bring out some of the oil dirt adsorbed on the inner wall of the oil guide pipe 140 into the sewage tank 520 , thereby cleaning the inside of the oil guide pipe 140 .

[0062] Reference Figures 8 to 10 In some embodiments, the mounting member 160 is connected to a blocking member capable of opening or blocking the second mounting hole 162 .

[0063] By adopting the above structure, when there is no need to clean the fan 210, the second mounting hole 162 can be blocked by the blocking piece to prevent foreign matter from entering the water pipe 150 through the second mounting hole 162 and polluting the water pipe 150. It also prevents the oil stains in the oil cup 400 from accidentally entering the water pipe 150 and polluting the water pipe 150 when the range hood is working normally.

[0064] Reference Figures 8 to 10 In some embodiments, the blocking member includes a plug-in portion 170 and a sealing plug 172. The plug-in portion 170 is inserted into the second mounting hole 162 and has a through hole 171 connected to the second mounting hole 162. The sealing plug 172 is movably connected to the plug-in portion 170 and can open or seal the through hole 171.

[0065] By adopting the above structure, the plugging member is provided as the plug-in portion 170 and the sealing plug 172, and the sealing plug 172 is movably connected to the plug-in portion 170, so that when the fan 210 needs to be cleaned, the sealing plug 172 only needs to be pulled out from the through hole 171, and when the fan 210 does not need to be cleaned, the sealing plug 172 is inserted into the through hole 171 to block the through hole 171, which is simple and convenient to operate, and because the sealing plug 172 is movably connected to the plug-in portion 170, there is no need to worry about the sealing plug 172 being lost due to improper placement by the user when opening the through hole 171. In addition, by inserting the plug-in portion 170 into the second mounting hole 162, it is also convenient to replace the plugging member in time when the plugging member is damaged.

[0066] It is understandable that the sealing plug 172 is movably connected to the plug-in portion 170. Specifically, the plug-in portion 170 and the sealing plug 172 can be connected by a flexible member that can be deformed under the action of an external force, such as a rubber member, a silicone member, etc. In addition, in order to effectively seal the via 171, the sealing member can be a flexible member such as a rubber member, a silicone member, etc.

[0067] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
