[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] See Figures 1 to 4 As shown, a range hood for hot air cleaning and oil removal includes a range hood body 1 and an air duct system 2 arranged in the range hood body. In this embodiment, the above structure is a conventional structure of the prior art, so it is not described in detail, but simply applied. In actual application, a hot air oil removal structure 3 is arranged on the air duct system; and the hot air oil removal structure includes a fan 31, an air duct 32 and a heating element 33, wherein the heating element is an electric heating wire or an electric heating tube; the temperature of the air duct blowing into the air duct system is 70-200°C. During installation, the fan is located on the outside of the top right side of the range hood body. When in use, the fan is started, and external air enters from the air inlet of the air duct, and is sent into the air duct system after being heated by the heating element. By blowing in high-temperature gas, the oil stains on the inner wall of the air duct system are melted and flow to the bottom wall of the air duct system under the action of gravity;

[0025] During the installation process, the fan is fixed to the top side of the air duct, and the heating element is fixed inside the air outlet end of the air duct; the bottom air outlet of the air duct passes through the top wall of the range hood body and is located on the top wall of the inner cavity of the air duct system; when in use, the fan is started, and air enters from the top air inlet of the air duct and is blown into the air duct system from the bottom air outlet after passing through the heating element.

[0026] In actual application, in order to better discharge the oil, an oil guide pipe 4 is provided on the bottom wall of the air duct system; the oil on the inner wall of the air duct system is discharged from the oil guide pipe. An oil cup 5 is provided at the bottom of the range hood body. The oil cup is a conventional structure of the prior art, which is simply used. The oil gradually flows to the bottom wall of the air duct system under its own gravity and is discharged from the oil guide pipe. The discharged oil will flow into the oil cup and gather.

[0027] In actual application, the range hood body is provided with a control switch 6 connected to the fan and the heating element. At the same time, in order to ensure its stability and reliability, a dustproof net is provided at the air inlet at the top of the air duct. The control switch is on the switch panel on the range hood body, which is more convenient to operate.

[0028] The utility model has positive effects: the structure of the utility model is reasonably arranged, and a hot air oil removal structure is arranged on the air duct system, and the hot air oil removal structure includes a fan, an air guide pipe and a heating element. When in use, the fan is started to allow external air to pass through the air guide pipe and the heating element, and hot air is blown into the air duct system. The high temperature gradually melts the oil stains on the inner wall of the air duct system, and the oil stains are discharged from the oil guide pipe on the bottom wall of the air duct system under the action of gravity. The utility model is not only convenient to operate, which is beneficial to improving the efficiency of oil removal, but also does not require professional personnel to disassemble and clean, which is beneficial to improving the cleaning efficiency, and will not affect the normal use of the range hood body, thereby ensuring the stability and reliability of the product, and having strong applicability and good practicality.

[0029] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0030] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
