For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The switch provided by the utility model can be installed on various kitchen appliances, such as range hoods, steam ovens, etc.

[0041] The switch comprises: a control box, wherein a main control circuit board 200 and at least two functional modules with different functions are arranged inside the control box.

[0042] like Figure 4As shown, the control box includes a box body 110 and a box cover 120, each functional module and the main control circuit board 200 are fixedly installed in the box body 110, and then the box cover 120 is connected to the box body 110 by means of screws or buckles.

[0043] The functional modules are all connected to the main control circuit board 200. The functional modules can send signals to the main control circuit board 200 and receive signals fed back by the main control circuit board 200. The main control circuit board 200 is connected to the power board outside the control box to uniformly supply power to each functional module. According to the spatial structure in the box body 110, the functional module and the functional adapter board can be directly connected, that is, the functional module is fixedly installed on the functional adapter board, or the functional module and the functional adapter board can be connected by wires.

[0044] The electrical connection between each functional module and the main control circuit board 200 is completed in the control box, and then the output end of the main control circuit board 200 is connected to the main controller, so that the signal is first transmitted to the main control circuit board 200, and then transmitted from the main control circuit board 200 to the main controller. Therefore, it is only necessary to connect the main control circuit board 200 to the main controller, which reduces the number of wiring and avoids the problem of cluttered leads. In addition, because the main control circuit board 200 is arranged inside the control box, the possibility of contamination of the main control circuit board 200 is also reduced, and its service life is increased.

[0045] like Figure 1 As shown, in a first practicable solution, at least one functional module includes a functional circuit board 300, and the functional circuit board 300 and the main control circuit board 200 are arranged at intervals in the up-down direction, wherein the up-down direction is the depth direction of the box body 110, the functional circuit board 300 is at the bottom, and the main control circuit board 200 is at the top. At least a partial area on the functional circuit board 300 is projected toward the plane where the main control circuit board 200 is located and falls on the main control circuit board 200, that is, in the up-down direction, the functional circuit board 300 and the main control circuit board 200 at least partially overlap, and the overlapping part is a non-interference part, that is, the parts of the functional circuit board 300 and the main control circuit board 200 that will generate signal interference are staggered, and other positions can overlap, thereby reducing the horizontal occupied space and shortening the horizontal length of the switch.

[0046] like Figure 2As shown, in the second practicable solution, at least two functional modules each have a functional circuit board 300, that is, there may be two or three functional modules in the switch, and at least two of these modules have a functional circuit board 300. At least two functional circuit boards 300 are arranged at intervals in the up-down direction, and there is at least a partial area on one of the functional circuit boards 300, and the projection of the partial area toward the plane where the other functional circuit board 300 is located falls on the main control circuit board 200. That is to say, in the up-down direction, the functional circuit boards 300 at least partially overlap each other, and the overlapping part is a non-interference part, that is, the parts of the functional circuit boards 300 that will generate signal interference are staggered, and other positions can overlap, thereby reducing the horizontal occupied space and shortening the horizontal length of the switch. In the case where there is enough space in the box body 110, the first embodiment and the second embodiment can be combined.

[0047] Specifically, Figure 4 and Figure 5 As shown, in this embodiment, one of the functional modules is a touch switch module, and the touch switch module includes an electrically connected sensing diaphragm 410 and a diaphragm circuit board 420, that is, the touch switch module as a functional module, its functional circuit board 300 is a diaphragm circuit board 420, and the sensing diaphragm 410 can be a black and white film or a color film. The sensing diaphragm 410 is attached to the front of the box body by structural adhesive, and the resistance of the sensing diaphragm 410 is changed by touching or applying pressure to the sensing diaphragm 410, thereby realizing the trigger button function. The sensing diaphragm 410 is connected to the outer wall of the control box. When the switch is connected to the panel component, the sensing diaphragm 410 contacts the glass panel of the panel component. The diaphragm circuit board 420 is located in the control box, and the diaphragm circuit board 420 can be fixed in the box body 110 by riveting, clamping or screwing. A through hole is provided on the front of the control box for the connecting cables between the sensing diaphragm 410 and the diaphragm circuit board 420 to pass through, wherein the cables are all connected to the back side of the sensing diaphragm 410. After the sensing diaphragm 410 is installed, the cables are hidden in the control box and cannot be seen.

[0048] Furthermore, the membrane circuit board 420 and the main control circuit board 200 are arranged at intervals in the vertical direction, and at least a portion of the main control circuit board 200 has a projection toward the plane where the membrane circuit board 420 is located, which falls on the membrane circuit board 420. That is to say, in the vertical direction, the membrane circuit board 420 and the main control circuit board 200 at least partially overlap, and the overlapping portion is a non-interference portion, that is, the portions of the membrane circuit board 420 and the main control circuit board 200 that will generate signal interference are staggered, and other positions can overlap, thereby reducing the horizontal occupied space and shortening the horizontal length of the switch.

[0049] like Figure 5As shown, in order to further reduce signal interference, there is a gap between the upper and lower overlapping parts of the diaphragm circuit board 420 and the main control circuit board 200, and an insulating layer is provided in the gap, that is, during the assembly process, glue can be injected between the diaphragm circuit board 420 and the main control circuit board 200, and the electrical gap between the two is isolated by the glue-filled insulating layer.

[0050] like Figure 5 As shown, the main control circuit board 200 has an installation area, and at least one functional module is installed on the installation area. In this embodiment, the functional modules installed on the main control circuit board 200 can be a Bluetooth module 510 and a WiFi module 520. In order to avoid the Bluetooth module 510 and the WiFi module 520 interfering with the membrane circuit board 420, the projection of the installation area toward the plane where the membrane circuit board 420 is located falls on the outside of the membrane circuit board 420 and is staggered from each other.

[0051] Of course, in other feasible solutions, the Bluetooth module 510 and the WiFi module 520 may also be arranged at other locations other than the main control circuit board 200 .

[0052] like Figure 5 As shown, the switch is installed in the installation bin of the panel component, the material of the installation bin is metal, and the main control circuit board 200 is provided with a notch 310 extending from its edge to the installation area, and the notch 310 is located on the side where the signal transceiver end of the functional module is located, thereby increasing the distance between the signal transceiver end and the installation bin and reducing signal interference with the metal installation bin.

[0053] like Figure 3 and Figure 6 As shown, in the above-mentioned embodiments, the functional circuit boards 300 or the functional circuit boards 300 and the main control circuit board 200 are all arranged in an up-down staggered manner, and in the third feasible solution, at least one functional module includes the functional circuit board 300, and the main control circuit board 200 and the functional circuit board 300 are coplanar, that is, the two are arranged side by side along the length direction of the box body 110, although it will cause the horizontal length of the control box to increase, it can directly solve the signal interference between the circuit boards. Alternatively, the projection of the main control circuit board 200 toward the plane where the functional circuit board 300 is located falls on the outside of the functional circuit board 300, that is, although the main control circuit board 200 and the functional circuit board 300 are arranged up and down, they do not overlap, and there will be no interference in the up and down directions.

[0054] Similarly, when there are multiple functional circuit boards 300, taking two of them as an example, the two functional circuit boards 300 may not overlap in the vertical direction, that is, the two functional circuit boards 300 may be coplanar. Alternatively, the projection of one functional circuit board 300 toward the plane where the other functional circuit board 300 is located falls outside the functional circuit board 300, that is, although the two functional circuit boards 300 are arranged up and down, they do not overlap, and there will be no interference in the vertical direction.

[0055] In an implementable solution, when there are more than three functional circuit boards 300 , two of the functional circuit boards 300 may overlap vertically, and two of the functional circuit boards 300 may not overlap vertically.

[0056] At least one functional module in the switch is a waving module 530, which can collect the user's waving action to trigger certain functions, such as turning on or off the fan of the range hood.

[0057] The kitchen appliance provided by the utility model includes the above switch. Since the kitchen appliance provided by the utility model uses the above switch, the kitchen appliance provided by the utility model also has the advantages of the switch.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
