Full-embedded range hood and opening and closing control method thereof

Abstract

The invention discloses a full-embedded range hood comprising a range hood main body, a main smoke collection cavity, an auxiliary smoke collection cavity, a steady flow plate, a first driving mechanism, a second driving mechanism, an oil smoke sensor and an electrical control system. The steady flow plate is opened and closed rotationally at the bottom of the auxiliary smoke collection cavity. The first driving mechanism drives the steady flow plate to rotate. The second driving mechanism drives the main smoke collection cavity to move up and down. The oil smoke sensor detects the oil smoke concentration of an oil smoke area in real time and feeds back the oil smoke concentration to the electrical control system. The electrical control system is in electric connection with the first driving mechanism and the second driving mechanism. The electrical control system judges the magnitude of the oil smoke concentration to control the strokes of the first driving mechanism and the second driving mechanism and then controls opening and closing angles of the steady flow plate and the moving-down stroke of the main smoke collection cavity. The invention further discloses an opening and closing control method of the full-embedded range hood. With the adoption of the full-embedded range hood and the opening and closing control method thereof, the work utilization rate of the range hood can be increased effectively, and the smoke collection effect of the full-embedded range hood can also be improved effectively.

Description

technical field [0001] The invention relates to a range hood, more specifically, to a fully embedded range hood and an opening and closing control method thereof. Background technique [0002] Fully embedded range hoods are deeply loved by users because they can be fully embedded in the cabinet, fit the overall cabinet, and have strong appearance consistency. In the existing technology, the fully embedded smoke machine uses a liftable smoke collection chamber, which can be retracted into the whole machine when the machine is turned off, which not only ensures the overall aesthetic appearance of the appearance, but also prevents the lifting smoke collection chamber from being polluted. And it can achieve the effect of anti-backflow to a certain extent; in addition, some are equipped with auxiliary smoke collection chambers. However, the size of the domestic cabinet determines the installation size of the fully embedded range hood. In the working state, the descending size of...

AI Technical Summary

Problems solved by technology

However, the size of the domestic cabinet determines the installation size of the fully embedded range hood. In the working state, the descending size of the liftable smoke collection chamber is fixed, and the height of the auxiliary smoke collection chamber is also fixed. This will cause the following problems : First, due to the structural size limitation, after the fully embedded range hood is fully lowered, there is a risk of interference with the domestic ordinary steamer; second, the lowering stroke of the movable smoke collection chamber cannot be selected at will No matter how big or small the fume is, the whole machine is fully open, which consumes a lot of energy; thirdly, the current fully embedded range hood has an unsatisfactory smoke collection effect due to the influence of the depth of the whole machine. In the cooking environment, especially at the moment of stir-frying, the oil fume will rise rapidly, and the oil fume that is not sucked away in time will be blown to the face of the user, causing trouble; fourth, in order to better realize the fully embedded function, the installation size of the range hood It is flush with the cabinet, and its installation height determines that the distance between the center of the air duct and the smoking port is elongated, so its smoking efficiency is lower than that of traditional side suction hoods
