a range hood

Abstract

The invention discloses a range hood, which comprises a smoke collecting hood and a movable smoke baffle. The movable smoke baffle includes a front smoke baffle and side smoke baffles arranged on the left and right sides of the front smoke baffle. The side smoke baffle consists of The connection with the front smoke baffle extends backwards, the rear end of the side smoke baffle is rotatably connected with the smoke collecting hood, and the center of the connection constitutes the rotation center of the movable smoke baffle, and the movable smoke baffle can be positioned at the position of the front smoke baffle. The front and side smoke baffles of the smoke collection hood are located at the closed position on the left and right sides of the smoke collection hood, and the movable smoke baffle can also be in an open position where the front smoke baffle is located at the lower front side of the smoke collection hood by rotating downward around the rotation center. Compared with the prior art, the present invention has the advantage that: by setting a movable smoke baffle around the smoke collecting hood, the movable smoke baffle can be rotated to the lower side of the smoke collecting hood during operation, forming A larger smoke collection cavity is provided, thereby expanding the working distance of the negative pressure area on the front side of the smoke collection hood cavity, reducing the chance of the rising oil fume escaping from the front side of the smoke collection hood, and the smoke collection effect is good.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] The range hood has become one of the indispensable kitchen appliances in modern families. The range hood works by using the principle of fluid dynamics. Grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] Although the range hood can suck most of the oil fumes when it is working, there are still some oil fumes near the front of the human body during the cooking process that are not completely sucked, so that the oil fumes can be directly breathed into the human body, which affects the heal...

Problems solved by technology

[0003] Although the range hood can suck most of the oil fumes when it is working, there are still some oil fumes near the front of the human body during the cooking process that are not completely sucked, so that the oil fumes can be directly breathed into the human body, which affects the health of the body, especially when cooking. The phenomenon of running smoke is more obvious when people move around

At present, two different methods are commonly used to solve this problem: 1) a fixed smoke baffle is arranged on the front side of the smoke collecting hood, but this structure increases the volume of the whole machine, which increases the packaging cost on the one hand, and on the other hand due to The fixed smoke baffle always occupies a certain space position, and if the position is unreasonable, it will easily reduce the user's operating experience; 2) The smoke collection structure of the air curtain, whether it is from top to bottom or bottom to top, when the wind force of the air curtain is small , the oil fume is difficult to be confined in the air curtain area; when the air curtain wind force is large, it will cause some interference to the thermal efficiency of the cooker and the user's use, and it is difficult to determine the working condition of the oil fume. have greater limitations

However, since the range hood itself already has a certain depth, when the hood is moved laterally to open, further expanding this depth will easily affect the user's sight, making it difficult to cook, and it is very easy to bump into each other and cause injury
