Description

Technical Field

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

[0002] When the existing T-shaped range hood switch assembly adopts a color film button, the switch color film button needs to be attached to the glass panel to ensure the sensitivity of touch control. The conventional solution is to set a spring on the switch assembly so that the switch assembly can be attached to the glass under the action of the elastic force of the spring. The disadvantage is that the spring occupies the space of the switch assembly, making the switch assembly relatively large and unsuitable for some range hoods with narrow switch assembly installation positions.

[0003] Therefore, there is an urgent need for a switch structure of a range hood to solve the above problems. Utility Model Content

[0039] Embodiment 1

[0040] Please refer to Figure 1-Figure 4The utility model provides a switch structure of a range hood, comprising a limit reinforcement member 4, a switch assembly 3, a spring piece 6 and a panel 2. The limit reinforcement member 4 is mounted on the smoke hood 1 of the range hood, and a limit accommodating cavity with a first opening on the front side is provided in the middle of the limit reinforcement member 4. The switch assembly 3 is placed in the limit accommodating cavity, and the switch assembly 3 comprises a switch box 31 and a switch body 32 arranged in the switch box 31, and the switch box 31 and the limit reinforcement member 4 are magnetic members with the same magnetic properties. The spring piece 6 is arranged on the rear side of the switch box 31 and abuts against the rear inner wall of the limit reinforcement member 4. The panel 2 is mounted on the smoke hood 1 and is located on the front side of the switch assembly 3, and the rear side of the panel 2 is in contact with the front side of the switch body 32.

[0041] The switch assembly 3 of the range hood provided by the utility model is provided with a spring sheet 6 on the rear side of the switch box 31, so that the switch box 31 can be pressed against the rear side of the panel 2 by the elastic force of the spring sheet 6, and the spring sheet 6 occupies a small space, so that the switch structure is more compact, which is conducive to the miniaturization of the structure. At the same time, by setting the switch box 31 and the limit reinforcement member 4 as magnetic members with the same magnetic properties, there is a repulsive force between the switch box 31 and the limit reinforcement member 4, and the switch box 31 as a whole can have the force to stick to the panel 2 under the action of the repulsive force, thereby ensuring that the switch assembly 3 is still affected by the repulsive force at a position where the spring sheet 6 is not provided, so that the front side of the switch body 32 in the switch assembly 3 can be evenly attached to the rear side of the panel 2, thereby improving the sensitivity of the user to control the switch assembly 3 through the panel 2.

[0042] Optionally, the limit reinforcement 4 is a metal magnetic part, and the switch box 31 is a plastic magnetic part. By setting the switch box 31 as a plastic magnetic part, the switch body 32 arranged in the switch box 31 can have a better insulation effect, thereby ensuring the communication stability of the switch body 32 and further ensuring the sensitivity of the switch assembly 3.

[0043] Optionally, at least two spring sheets 6 are provided, and the at least two spring sheets 6 are evenly arranged on the rear side of the switch box 31 to evenly provide elastic force for the switch assembly 3 .

[0044] Optionally, a connecting member 5 is further included, and the connecting member 5 is installed on the smoke hood 1 . The limiting reinforcement member 4 is provided with a connecting portion 41 , and the connecting portion 41 is connected to the connecting member 5 , so that the limiting reinforcement member 4 is installed on the smoke hood 1 .

[0045] Optionally, the connecting portion 41 is detachably connected to the connecting member 5 by screws, so that the limiting reinforcement 4 can be detachably installed on the smoke hood 1. When the switch assembly 3 needs to be replaced or repaired, the limiting reinforcement 4 can be removed by screws, and then the switch assembly 3 can be taken out from the accommodating cavity of the limiting reinforcement 4.

[0046] Optionally, a cover plate 7 is further included, and the cover plate 7 is covered on the upper side of the switch assembly 3. By arranging the cover plate 7, the switch structure is covered in the smoke collecting hood 1, which has an aesthetic effect.

[0047] Optionally, the cover plate 7 is mounted on the connecting member 5 , thereby achieving installation on the smoke collecting hood 1 .

[0048] Optionally, two connecting members 5 are provided, and a connecting member 41 is provided on the left and right parts of the limiting reinforcement 4 . The connecting member 41 on the left part of the limiting reinforcement 4 is connected to one connecting member 5 , and the connecting member 41 on the right part of the limiting reinforcement 4 is connected to another connecting member 5 .

[0049] Embodiment 2

[0050] Please refer to Figure 5-Figure 8 The difference between the second embodiment and the first embodiment is that: a second opening communicating with the accommodating cavity is provided on the upper side of the position-limiting reinforcement member 4. By providing the second opening, when the switch assembly 3 needs to be replaced or repaired, the switch assembly 3 can be directly taken out of the accommodating cavity of the position-limiting reinforcement member 4 through the second opening without first removing the position-limiting reinforcement member 4, which is convenient for the repair and replacement of the switch assembly 3. Since the second opening is provided on the upper side of the position-limiting reinforcement member 4, the switch assembly 3 is limited in the accommodating cavity by the cover plate 7 covering the upper side of the switch assembly 3, thereby achieving the limiting effect on the switch assembly 3.

[0051] In this embodiment, since there is no need to disassemble the limiting reinforcement member 4, optionally, the connecting portion 41 is directly welded to the connecting member 5, and the structure is simple and stable.

[0052] Another aspect of the present invention provides a range hood, comprising a fume collecting hood 1 and the switch structure of the range hood.

[0053] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
