Description

a range hood

technical field

The invention relates to the technical field of range hoods, in particular to an automatic degreasing range hood.

Background technique

The range hood needs to be cleaned regularly. Simple cleaning cannot remove the oil stains. To clean the range hood, a professional cleaning agent must be used for cleaning. The degreasing effect of the range hood is poor, which cannot meet the needs of cleaning. In addition, there is also the disadvantage that the range hood has a low wind pressure and is greatly affected by wind resistance.

Contents of the invention

The purpose of the present invention is to provide a range hood for automatic degreasing. The atomized cleaning agent flows through the diversion air duct, and the heater heats it to make the oil stain fall off, and the decontamination efficiency is high. It can better overcome the influence of wind resistance.

The technical solution of the present invention is: a range hood, including a shell, a conical cover, and a smoke collecting cavity, the shell, the conical cover, and the smoke collecting cavity are all formed of sheet metal and connected sequentially from top to bottom, the An obliquely arranged oil-gas separation cover is clamped between the lower inner walls of the shell, the angle between the oil-gas separation cover and the horizontal plane is 10° to 30°, and the upper inner wall of the shell is provided with a trumpet-shaped cavity. A guide air duct is formed between the cavities, and the top of the cavity is horizontally provided with a mounting frame, and the middle part of the lower surface of the mounting frame is fixed with a drive motor, and a motor shaft is provided below the drive motor. The bottom end of the rotating shaft and the middle part of the motor rotating shaft are provided with fan blades matching the inner wall of the cavity, and the inner top of the cavity is provided with an inclined platform with a microporous structure and a cross-sectional angle of 150 degrees.

The middle part of the cavity is a cavity structure, the inner wall of the cavity is wound with a heater, an ultrasonic generator is installed at the bottom of one side of the cavity, and a cleaning agent box is arranged above the ultrasonic generator. One side of the detergent box is provided with a liquid inlet installed on the shell.

The bottom side of the shell is provided with a fixed bracket, and the fixed bracket is provided with a detachable oil collecting bottle. The bottom end of the oil and gas separation cover.

The middle part of the outer wall of the smoke collecting chamber is provided with an LED display screen, and both sides of the LED display screen are provided with control knobs installed on the outer wall of the smoke collecting chamber.

Both sides of the top of the shell and both sides of the middle of the shell are provided with bolt hole hangers.

Beneficial effect

1. The air flow is discharged from the diversion air duct, and the oil and gas separation cover is used to block most of the oil stains. The ultrasonic generator atomizes the detergent in the detergent box, and the drive motor reverses at a low speed, and the atomized detergent flows through the diversion The air duct is heated by the heater to make the oil fall off, and enter the oil collection bottle through the connecting nozzle along the inclined oil and gas separation cover. The decontamination efficiency is high, and the fan blades installed in double layers are powerful enough to better overcome the influence of wind resistance.

Detailed ways

As shown in Figure 1-2, a range hood includes a casing 1, a conical cover 2, and a smoke collection chamber 3. The smoke collection chamber 3 is used to collect oil fume. The sheet metal is formed and connected sequentially from top to bottom. An oblique oil-gas separation cover 4 is clamped between the lower inner walls of the shell 1. The angle between the oil-gas separation cover 4 and the horizontal plane is 10 degrees to 30 degrees. The shell 1 The inner wall of the upper part is provided with a trumpet-shaped cavity 5, which is used to reduce wind resistance and provide installation space at the same time. A guide air duct 6 is formed between the cavity 5, and a mounting frame 7 is installed horizontally on the top of the cavity 5. , the middle part of the lower surface of the mounting frame 7 is fixed with a drive motor 8, and the motor shaft 9 is arranged below the drive motor 8, and the bottom end of the motor shaft 9 and the middle part of the motor shaft 9 are provided with fan blades that cooperate with the inner wall of the cavity 5 10. On the inner side of the top of the cavity 5, there is an inclined platform 11 with a microporous structure and a cross-sectional angle of 150 degrees. The middle part of the cavity 5 is a cavity structure. The inner wall of the cavity 5 is wound with a heater 12. One side bottom end is equipped with ultrasonic generator 13, and the top of ultrasonic generator 13 is provided with cleaning agent box 14, and one side of cleaning agent box 14 is provided with the liquid inlet 15 that is installed on the casing 1, and the bottom end of casing 1 one There is a fixed bracket 16 on the side, and a detachable oil collection bottle 17 is arranged on the fixed bracket 16. The lower part of the shell 1 is provided with a connecting nozzle 18 matched with one end of the oil collecting bottle 17, and the connecting nozzle 18 is arranged at the bottom of the oil-gas separation cover 4 end, the middle part of the outer wall of the smoke collecting chamber 3 is provided with an LED display 19, and both sides of the LED display 19 are provided with control knobs 20 installed on the outer wall of the smoke collecting chamber 3, the two sides of the top of the housing 1 and the middle of the housing 1 Both sides are provided with bolt hole hangers 21.
