[0034] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0035] This utility model provides an automatic cleaning range hood, comprising: a range hood body 1 and an oil removal component. An oil fume separation screen 11 is provided at the air inlet of the range hood body 1, and the oil fume separation screen 11 is arranged vertically or at an angle. The oil removal component is disposed inside the range hood body 1, and has an oil removal outlet facing the oil fume separation screen 11, capable of blowing hot air or spraying hot steam onto the oil fume separation screen 11.

[0036] Example 1

[0037] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, in this embodiment, the oil removal component includes a flow guide 2 and a heating element 3. Both the flow guide 2 and the heating element 3 are disposed inside the main body 1 of the range hood. The oil removal outlet of the flow guide 2 faces the oil fume separation net 11, and the heating element 3 is located at the air inlet end of the flow guide 2 or between the oil removal outlet of the flow guide 2 and the oil fume separation net 11.

[0038] Specifically, the aforementioned air intake component 2 includes an air duct 21, an impeller 22, and a motor 23. The air duct 21 is located inside the main body 1 of the range hood, with its outlet facing the oil fume separation mesh 11. The impeller 22 and the motor 23 are both located inside the air duct 21, and the impeller 22 is connected to the output end of the motor 23. In practical application, the main body 1 of the range hood is equipped with a control switch electrically connected to the oil removal component. The control switch can control the oil removal component. When the automatically cleaning range hood stops working, the oil removal component is activated by the control switch. The motor 23 is powered on, driving the impeller 22 to rotate. This causes outside air to enter the air duct 21 through the air inlet under the action of the impeller 22, and is heated by the heating element 3 to become hot air. The hot air is blown out of the air duct 21 through the air outlet under the action of the impeller 22 and blown towards the oil fume separation mesh 11. The grease adsorbed on the oil fume separation mesh 11 flows down along the oil fume separation mesh 11 under the action of the hot air, making the oil fume separation mesh 11 clean.

[0039] It is understandable that the air outlet of the aforementioned air duct 21 is the oil removal outlet of the guide component 2.

[0040] Understandably, after the degreasing component is started, it can either shut down automatically after a predetermined running time, or it can be shut down again via a control switch.

[0041] Specifically, the heating element 3 mentioned above can be a heating wire, a heating tube, or a heating plate.

[0042] Specifically, there are two oil removal components and two oil fume separation nets 11. The two oil fume separation nets 11 increase the contact area between the oil fumes generated during cooking and the oil fume separation nets 11, thereby improving the oil fume purification rate.

[0043] Through the above technical solution, the flow guide 2 can blow the hot air generated by the heating element 3 when it is powered on towards the oil fume separation net 11, so that the grease adsorbed on the oil fume separation net 11 flows down along the oil fume separation net 11 under the action of the hot air, making the oil fume separation net 11 clean, so as to ensure that a good purification rate can still be achieved in subsequent use.

[0044] like Figure 4As shown, in some preferred embodiments, the aforementioned air duct 21 is provided with an arc-shaped air guide plate 24. One end of the arc-shaped air guide plate 24 is tangentially arranged to the top wall of the air inlet of the air duct 21, and the other end of the arc-shaped air guide plate 24 is tangentially arranged to the rear wall of the air outlet of the air duct 21. Through the above technical solution, the air entering the air duct 21 through the air inlet can be accurately guided to the air outlet of the air duct 21 under the action of the arc-shaped air guide plate 24, thereby allowing more hot air to be blown towards the oil fume separation net 11, so as to achieve a better cleaning effect.

[0045] In practical applications, the oil fume separation mesh 11 is usually composed of two interlocking mesh plates, forming an oil fume channel between the two mesh plates. To ensure that the oil fume channel can also be cleaned, such as... Figure 2 and Figure 5 As shown, in some preferred embodiments, the aforementioned guide member 2 is located above the oil fume separation mesh 11. The top of the oil fume separation mesh 11 has a first through hole 111 that communicates with the oil fume channel inside the oil fume separation mesh 11, and the first through hole 111 faces the oil removal outlet (the air outlet of the air duct 21). Through this technical solution, the hot air blown out from the air outlet of the air duct 21 can flow from the top to the bottom of the oil fume separation mesh 11 and can enter the oil fume channel through the first through hole 111. In this way, the grease adsorbed on the inner wall (i.e., the inner wall of the mesh plate) and the outer wall of the oil fume separation mesh 11 can flow down along the oil fume separation mesh 11 under the action of the hot air, making the oil fume separation mesh 11 cleaner.

[0046] like Figure 7 and Figure 8 As shown, in some preferred embodiments, the air inlet of the above-mentioned range hood body 1 is provided with an upper mounting plate 12 and a lower mounting plate 13. The upper mounting plate 12 is provided with a first groove 121 and a second through hole, and the lower mounting plate 13 is provided with a second groove 131. The top end of the oil fume separation net 11 is located in the first groove 121, the first through hole 111 is connected to the first groove 121, and the bottom end of the oil fume separation net 11 is located in the second groove 131. With this technical solution, not only can the oil fume separation net 11 be detachably installed at the air inlet of the range hood body 1 for convenient use, but it also does not affect the hot air entering the oil fume channel to clean the oil filter adsorbed on the inner wall of the oil fume separation net 11 (i.e., the inner wall of the mesh plate). Specifically, the hot air blown out from the air outlet of the air duct 21 enters the oil fume channel in sequence through the second through hole, the first groove 121, and the first through hole 111.

[0047] It should be noted that when the oil fume separation mesh 11 is installed at the air inlet of the main body 1 of the range hood, the bottom end of the oil fume separation mesh 11 abuts against the bottom of the second groove 131, and there is a gap between the top end of the oil fume separation mesh 11 and the bottom of the first groove 121. When it is necessary to remove the oil fume separation mesh 11, push the oil fume separation mesh 11 upward so that the top end of the oil fume separation mesh 11 abuts against the bottom of the first groove 121. At this time, the bottom end of the oil fume separation mesh 11 comes out from the second groove 131. Then, push the oil fume separation mesh 11 downward at an angle so that the top end of the oil fume separation mesh 11 comes out from the first groove 121, and the oil fume separation mesh 11 can be removed.

[0048] like Figure 6 , Figure 7 and Figure 8 As shown, in some preferred embodiments, the bottom end of the oil fume separation mesh 11 is provided with an oil drain hole 112, which communicates with the second groove 131. The lower mounting plate 13 is provided with an oil drain hole 132, which communicates with the second groove 131. The range hood body 1 is provided with a detachable oil cup, which is located below the oil drain hole 132 when it is installed on the range hood body 1. With this technical solution, the grease flowing down along the oil fume separation mesh 11 can flow into the oil cup through the oil drain hole 112, the second groove 131 and the oil drain hole 132 in sequence and be collected. Users can periodically remove the oil cup for cleaning to prevent grease from dripping everywhere.

[0049] like Figure 7 and Figure 9 As shown, in some preferred embodiments, the range hood body 1 is provided with an oil receiving plate 14, which is located below the turbine fan 15 installed inside the range hood body 1. An oil drain pipe 141 is formed on the oil receiving plate 14, and the oil drain pipe 141 is connected to an oil collecting cup via a pipe. This technical solution allows the oil receiving plate 14 to collect the oil dripping from the turbine fan 15. The oil collected by the oil receiving plate 14 flows through the oil drain pipe 141 and the pipe to the oil collecting cup for collection, preventing the oil dripping from the turbine fan 15 from accumulating inside the range hood body 1.

[0050] like Figure 1 As shown, in some preferred embodiments, a baffle 4 is hinged to the main body 1 of the range hood, and the baffle 4 movably corresponds to the air inlet of the main body 1. In specific applications, the baffle 4 can be opened when the automatic cleaning range hood is started, which helps to increase the area for blocking oil fumes and prevent oil fumes from escaping, thereby improving the oil fume extraction rate of the automatic cleaning range hood; after the range hood is turned off, the baffle 4 is closed, which helps to reduce the space occupied and also prevents dust, flying insects, etc. from sticking to the oil fume separation net 11 at the air inlet, which helps to keep the oil fume separation net 11 clean. Specifically, the baffle 4 can be opened or closed manually or electrically.

[0051] Example 2

[0052] like Figure 10 As shown, the difference between this embodiment and embodiment one is that: in this embodiment, the oil removal component includes a steam generator 5 and a nozzle 6. Both the steam generator 5 and the nozzle 6 are installed inside the main body 1 of the range hood. The water inlet of the steam generator 5 is connected to the water supply device through a pipe, and the steam outlet of the steam generator 5 is connected to the nozzle 6 through a pipe. The oil removal outlet of the nozzle 6 faces the oil fume separation net 11.

[0053] In practical applications, the oil removal component can be controlled by a control switch. When the automatic cleaning range hood stops working, the oil removal component is activated by the control switch. The water supply device provides water to the steam generator 5, which converts the water into hot steam. The hot steam is sprayed out from the nozzle 6 and onto the oil fume separation screen 11. The grease adsorbed on the oil fume separation screen 11 flows down along the oil fume separation screen 11 under the action of the hot steam, making the oil fume separation screen 11 clean.

[0054] It is understandable that the outlet of nozzle 6 mentioned above is the oil removal outlet of nozzle 6.

[0055] Specifically, there can be multiple nozzles 6, which can spray steam into the oil fume separation net 11 from multiple directions to achieve a better cleaning effect.

[0056] Specifically, the aforementioned water supply device can be an externally mounted water tank for an automatically cleaning range hood. Preferably, the water in the tank can be pumped into the steam generator 5 by a water pump.

[0057] In summary, in one or more embodiments of this utility model, the automatic cleaning range hood of this utility model has an oil removal component with an oil removal outlet facing the oil fume separation net inside the main body of the range hood. This allows the oil removal component to blow hot air or spray hot steam onto the oil fume separation net through the oil removal outlet, thereby causing the grease adsorbed on the oil fume separation net to flow down along the oil fume separation net under the action of hot air or hot steam, making the oil fume separation net clean and ensuring that a good purification rate can still be achieved in subsequent use.
