Embodiment Construction

[0015] During the implementation of this patent, traditional processing techniques are used to assemble sheet metal and plastic molded parts. The construction of the indoor and outdoor convection system is completed by using the method of large tubes and small tubes to realize the convection function. The large pipe introduces outdoor air into the room through passive suction, is discharged from the designed convection outlet, and descends to form an air curtain. The rising oil fume heat passes through the Qi-shaped global rectification cover （注2） The rectification is squeezed from the middle to the periphery, the flow velocity increases, and it flows to the base of the fairing, which is the oil fume suction port on the edge of the range hood. The low-temperature and low-velocity high-pressure air of the peripheral air curtain will squeeze the rising high-velocity hot oily fume low-pressure airflow, forming a surround for the rising oily fume hot airflow. Prevent oil fum...

Abstract

The invention discloses a convection type rectifying edge air suction lampblack removal mode, and belongs to the technical field of household appliance products. Due to popularization of modern household air conditioning equipment, a closed space is formed in the household environment. In the use process of a range hood, indoor air and outdoor air cannot achieve convection, the air pressure difference is increased, the sucking rate is lowered, and the lampblack removal efficiency is reduced. Due to the structural factor of the range hood, turbulent flow appears in the process that lampblack gas enters a suction opening, the lampblack gas overflows, and the lampblack removal efficiency is influenced. According to the mode, an air inlet channel is additionally arranged on the range hood, the outdoor air is introduced into a room, the range hood has the convection condition, the indoor air conditioning environment is protected, and smooth smoke exhausting conditions are provided. Based on the aerodynamics principle, it is designed that an air curtain is formed on the periphery of the range hood through the introduced outdoor air, and lampblack overflowing is avoided. The structure of the range hood is optimized. Rising smoke is guided into the suction opening in the edge of the range hood through a global fairing, it is guaranteed that lampblack gas generated in the cooking process can be completely exhausted, and therefore the lampshade removal function is improved.

Description

technical field [0001] Home appliance. Background technique [0002] The standard of a good range hood should be measured by its smoke removal effect. Range hoods on the market, whether they are top-suction or side-suction, are designed to provide better smoke removal effects. However, in actual use, there are some factors that limit the smoke removal efficiency, which have not been paid attention to and solved, resulting in insufficient oil smoke removal effect. The first is environmental factors: due to the use of air-conditioning equipment in modern homes, it is rare to open windows or doors for a long time, or consciously open windows and doors when cooking. The entire indoor environment forms a closed space. When the range hood is working, the range hood draws air from the room to the outside. In the absence of convection, the pressure difference between indoor and outdoor increases, and the air extraction volume decreases due to the increase in pressure difference. ...
