With the improvement of material living standards, people's requirements for the kitchen environment are getting higher and higher, and the practicality and frequency of use of range hoods are getting higher and higher. In this way, the oil net and the impeller of the range hood including the entire air duct system will accumulate a large amount of oil, and will not be cleaned for a long time, which will affect the air volume, wind pressure and noise of the range hood, thereby affecting the range hood. Smoke extraction effect and service life. In response to the above problems, by installing an intelligent self-cleaning component on the household range hood, the impeller and the oil net of the range hood are automatically cleaned to achieve the best cleaning effect on the internal structure of the range hood, and the best improvement of the range hood is ensured. The clean and smart kitchen environment.
2 self-cleaning core function and working principle The self-cleaning core of the household range hood has the following functions: the first layered three-dimensional washing technology, which realizes 360 degree cleaning without dead angle; intelligent 12 minute cleaning, 2 high speed separation, 3 minutes drying design; Five safety protections to improve the safety of the range hood.
After self-cleaning core hoods are operated by intelligent monitoring of the range hood for 15 hours, the air duct and oil net of the range hood are self-cleaned, and the motor is controlled by the computer board to keep the low speed running, ensuring that the impeller of the duct system can achieve 360 ​​without Dead angle cleaning, when the control module detects that the feedback temperature of the sensor reaches 130T, the solenoid valve automatically opens the purified pure water in the pumping cup and delivers it to the heating body to generate high temperature steam (120-130) to the air duct of the range hood (mainly For impeller and oil net cleaning, high temperature steam cleaning impeller and oil net for 12 minutes, intermediate design 6th and 9th minute high speed oil design, when cleaning is completed, suck), male, now working for Qingdao Haier Dishwasher Co., Ltd. is mainly engaged in the research of electronic control and self-cleaning core module of range hood. The air duct system of the 872-disc hood is dried for 3 minutes at high speed to solve the user's traditional cleaning of the range hood and improve the safety and usability of the whole machine. The structure of the self-cleaning core system of the range hood is as shown.

The self-cleaning core module plays a central role in the cleaning function of the range hood. The module adopts an integrated design, including heating body, electromagnetic pump, thermostat, pressure relief valve and temperature sensor.
The integrated design of the self-cleaning core module not only saves the space occupied by the module assembly, but also realizes the “seamless†connection of each module, and maximizes the optimal effect of the integrated module.
The life of the self-cleaning core module can reach more than 1000 cycles, which can effectively meet the needs of users to clean the oil hood of the range hood. The self-cleaning core module is integrated as shown.
The side suction type oil net assembly adopts three rib reinforcement design schemes (see ,). The advantages of this type of fixing method are mainly the following four points.
The tubing can be placed behind the ribs for easy concealment as shown.
Three ribs act to fix the nozzle.
The concave oil net design can increase the negative pressure zone and enhance the smoking effect of the range hood.
Subvert the traditional oil net and the inlet ring separately.
The side suction nozzle type scheme is as shown, the red line is the steam range, and both cover the height of the entire impeller. According to the above design concept of comprehensive coverage of the impeller, the design of the aluminum tube and the position of the opening to ensure that the steam can cover the whole impeller. The design of the European flat-plate type nozzle should be considered from the perspective of comprehensive cleaning. For the double impeller (see), the comprehensiveness should be considered in the design and installation of the nozzle. As shown, the flat-plate type nozzle (see) provides effective and comprehensive coverage of the double-layer impeller, which can achieve 360 ​​without dead angle. Cleaning.
Let the air pressure in the valve chamber 1 be /, the volume is h, the air pressure in the valve chamber 2 is P2, the volume is F2, and the pressure at the water inlet is P (external pressure); when there is no power, the pressure in the valve chamber is = P2 = P (consistent with external atmospheric pressure).
A diode must be connected in series to cut off the reverse voltage portion of the alternating current. Within one cycle, half of the electric field is turned on, and the other half is not turned on or off (see 1).
When the electromagnetic coil is energized, the magnetic force of the electromagnetic ring to the right of the plunger is that the plunger moves to the right under the action of the force, and the force of the spring on the plunger = the compression distance of the spring, m. When the plunger moves to the right, the volume F2 of the valve chamber 2 becomes larger, the pressure P2 becomes smaller, and the volume R of the valve chamber 1 becomes smaller, and the pressure becomes larger, at this time P2
Haier deep cavity self-cleaning core range hood has been tested by authoritative organizations, and the washing rate has reached 99.2%. Haier deep cavity self-cleaning core range hood is not only in cleaning performance but also in the industry leading 7C level. With the country's awareness of energy conservation and emission reduction and environmental protection, this new idea, new program, and new products will certainly be accepted by the public and become a representative of innovative thinking.
