Description

Technical Field

[0001] The utility model relates to a switch on a household appliance, in particular to a switch on a range hood. Background Art

[0002] Kitchen fumes can easily make the environment greasy. Range hoods, as a kitchen appliance that purifies the kitchen environment, have become a powerful tool for improving it. They transform the overall kitchen environment by quickly extracting harmful fumes, which are harmful to the kitchen environment and the human body, and exhausting them outdoors, reducing pollution and purifying the air. Range hoods have become an essential kitchen appliance in modern households.

[0003] While range hoods purify the kitchen environment, they themselves are still susceptible to oil fume pollution. Therefore, range hoods are constantly being refined, both in terms of technology and control. For example, early mechanical switches evolved into computer-controlled switches (touch buttons), and now are commonly used touch-screen computer-controlled switches. Touch-screen switches allow the operating surface to be a solid piece of glass, shielding the control panel from direct oil fume contamination and potentially damaging it. However, touch-screen switches require direct user contact, which can be inconvenient in real-world situations. For example, when the user's hands are dirty or cluttered, it can be difficult to operate. Therefore, contactless range hood control offers advantages. Utility Model Content

[0008] The switch disclosed herein utilizes an internal infrared sensor device to enable gesture-controlled sensor switching, solving the problem of contactless range hood control and offering the advantage of ease of use.

[0024] The following is further described in detail through specific implementation methods:

[0025] The figure marks in the drawings of the specification include: housing 1, base 2, control board 3, infrared sensing device 4, infrared emitting unit 5, infrared receiving unit 6, top frame 7, light partition 8, light-transmitting hole 9, panel 10, first surrounding frame 11, bottom plate 12, second surrounding frame 13, card hole 14, buckle 15, screw seat 16, gasket 17, connecting frame 18.

[0026] As attached Figure 1-3 As shown, this embodiment shows a switch, including a housing 1 and a base 2 connected to each other, a control board 3 is arranged between the housing 1 and the base 2, and infrared sensing devices 4 are respectively arranged at both ends of the control board 3.

[0027] Among them, the infrared sensing device 4 includes an infrared emitting unit 5, an infrared receiving unit 6 and a top frame 7. The infrared emitting unit 5 and the infrared receiving unit 6 are respectively connected to the control board 3 and are both arranged in the top frame 7. A light partition 8 is arranged in the top frame 7. The infrared emitting unit 5 and the infrared receiving unit 6 are respectively arranged on both sides of the light partition 8. Two light-transmitting holes 9 are opened at the top of the top frame 7. The positions of the two light-transmitting holes 9 are respectively arranged relative to the positions of the infrared emitting unit 5 and the infrared receiving unit 6; the outer shell 1 is made of a light-transmitting material.

[0028] The working principle of the switch of this embodiment is as follows: the signal emitted by the infrared emitting unit 5 is emitted through the light-transmitting hole 9 of the top frame 7 and the outer shell 1, and after being reflected by the external human body or object, the infrared receiving unit 6 receives the infrared signal and sends it to the control board 3, thereby realizing the control of operations such as turning on or off the range hood.

[0029] Among them, the light partition 8 separates the infrared emitting unit 5 and the infrared receiving unit 6 in the top frame 7, preventing the infrared rays emitted by the infrared emitting unit 5 from being directly received by the adjacent infrared receiving unit 6, thereby preventing the induction switch from malfunctioning.

[0030] Specifically, the housing 1 includes a panel 10 and a first frame 11. The panel 10 is generally elongated and elliptical in shape. The first frame 11 is disposed below the panel 10 and has an overall elongated and elliptical cross-section. The base 2 includes a bottom plate 12 and a second frame 13. The bottom plate 12 is generally elongated and elliptical in shape, and the second frame 13 has an overall elongated and elliptical cross-section.

[0031] The shape and size of the control panel 3 are adapted to those of the second frame 13 to reduce shaking of the control panel 3 in the housing 1 .

[0032] The first frame 11 has latch holes 14 on its sidewalls, and the second frame 13 has latches 15 on its sidewalls. These latches 15 engage with the latch holes 14. The latch holes 14 and latches 15 cooperate to achieve the initial connection and assembly between the housing 1 and the base 2. At least two screw seats 16 are provided within the second frame 13, which connect the housing 1, control board 3, and base 2 together using screws. Screws are then used to further secure the housing 1, control board 3, and base 2.

[0033] A gasket 17 is provided between the control board 3 and the screw seat 16. The gasket 17 is used to protect the control board 3 and reduce the pressure from the screw to prevent the control board 3 from being deformed.

[0034] Specifically, a connecting frame 18 is provided on one side of the top frame 7. Screws are screwed into the screw seat 16, the connecting frame 18 and the shell 1 at one time to fix the base 2, the top frame 7 and the shell 1 together.

[0035] In this embodiment, the housing 1 is made of acrylic material. Acrylic material allows light to pass through. Of course, other light-transmitting materials can also be used to make the housing 1, without limitation.

[0036] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
