Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a mounting structure for a range hood switch. Background Art

[0002] A switch for controlling the operation of the range hood is generally provided on the front side wall or front panel of the existing range hood housing. The switch installation methods can be divided into hidden and directly exposed types. The directly exposed switch installation structure, such as the structure disclosed in the Chinese utility model patent with patent number 201220640086.0 (authorization announcement number CN202973280U), has a first opening for embedding the switch on the front panel of the range hood, and first brackets parallel to the horizontal plane are fixed on the left and right sides of the first opening on the inner side of the front panel, respectively. The left and right ends of the switch are fixed to the first bracket in the upper and lower directions by screws.

[0003] To enable exposed installation of the switch, the opening on the range hood is generally larger than the exposed surface of the switch. During actual installation, factors such as positioning deviations can result in an uneven gap between the exposed surface of the switch and the edge of the opening, with one side showing a larger gap than the other, thus affecting the overall refinement of the range hood.
