Smoke exhaust ventilator

[ technical field ] A method for producing a semiconductor device

The invention relates to a range hood, in particular to a range hood which comprises a body and a suspension device.

[ background of the invention ]

With the improvement of living standard of people, the kitchen design is one of the key points of modern household design, and the kitchen design not only is a place for people to cook food, but also shows the living quality of people. The existing range hood body is usually installed in a kitchen through a hanging device fixed on a wall or a ceiling. The body is hung on the hook of the hanging device through the hanging hole arranged on the body. In order to prevent the range hood from falling off, the hook of the suspension device inclines upwards when the suspension device is in a use state, namely, the vertical section of the hook forms an included angle of not 90 degrees with the gravity direction.

The matching of the size and height of the cabinet to the kitchen appliance is important not only for the suppliers engaged in the overall sale of kitchen appliances and cabinets, but also for the average household user. For example, it is desirable that the bottom end of the range hood body is flush with the bottom end of the cabinet, which makes the layout of the kitchen consistent. For the inclined hook, the range hood body has a descending process after being hung on the hook, so a range hood manufacturer has to estimate the descending height of the range hood body in advance when the range hood body is installed so as to enable the range hood body to be flush with the bottom end of the cabinet after the range hood body is installed. However, this approach does not guarantee the desired results. Because the hook is inclined upwards, the hook and the hanging hole which are manufactured under the current processing precision are difficult to ensure that the hanging hole is accurately hung at the same position of the hook, and the descending height of the body is difficult to accurately estimate. Therefore, the bottom end of the range hood body installed by the method has a certain drop with the bottom end of the cabinet, and the requirements cannot be completely met.

[ summary of the invention ]
