[0052] like Figure 3 As shown, the switch fixing bracket 100 provided by the utility model is used to be installed on the glass panel 200 , and comprises: a mounting plate body, the front side of the mounting plate body is in contact with the back side of the glass panel 200 .

[0053] like Figure 1 As shown, the mounting plate is provided with a switch mounting hole 120 that runs through both the front and back sides thereof, and the shape and area of ​​the switch mounting hole 120 are substantially consistent with the projection shape and area of ​​the switch assembly 300. After the switch fixing bracket 100 is attached to the glass panel 200, the switch assembly 300 is placed into the switch mounting hole 120, so that the display screen 322 on the front of the switch assembly 300 is attached to the glass panel 200.

[0054] The front side of the mounting plate has a recessed portion 110 that is recessed toward the back side thereof. The shape of the recessed portion 110 is determined according to the shape of the mounting plate, and may be a regular shape or an irregular shape.

[0055] The recess 110 is spaced apart from the switch mounting hole 120 . The recess 110 is used to contain the adhesive 400 . The recess 110 is not connected to the switch mounting hole 120 . Therefore, the adhesive 400 placed in the recess 110 will not overflow inward.

[0056] like Figure 1 and Figure 2 As shown, when the switch fixing bracket 100 is installed with the glass panel 200, the worker can drop the adhesive 400 into the recess 110, and then fit the front of the mounting plate body with the back of the glass panel 200. The front of the mounting panel is completely fitted with the glass panel 200, and the adhesive 400 in the recess 110 bonds the glass panel 200 and the mounting plate body together, and the recess 110 plays the role of retaining adhesive. In addition, since the front of the mounting plate body is fitted with the glass panel 200 as a whole, the adhesive 400 can be restricted in the recess 110, so as to prevent the adhesive 400 from flowing to the switch mounting hole 120, and prevent the adhesive 400 from overflowing inwards and contaminating the display area of ​​the glass panel 200 and the switch assembly 300.

[0057] According to different structures at different positions on the mounting plate, recesses 110 of different shapes can be provided. In one practicable manner, for example Figure 2 and Figure 5 As shown, the recess 110 extends to the outer edge of the mounting plate body. Such a recess 110 is generally arranged at a narrow edge and a position where it is difficult to open a hole. In this embodiment, such a recess 110 can be arranged on the upper and lower sides of the switch mounting hole 120. Taking the recess 110 on the lower side of the switch mounting hole 120 as an example, the recess 110 directly extends to the lower edge of the mounting plate body, that is, an open recess 110 is formed. When this recess 110 is bonded to the glass panel 200, a glue overflow port 140 can be formed below the mounting plate body and the glass panel 200. When too much adhesive 400 is placed in the recess 110, it plays a role in guiding the glue overflow to prevent the glue from overflowing inward and contaminating the display area of ​​the glass panel 200 and the switch assembly 300.

[0058] In another possible implementation, Figure 1 As shown, a glue overflow hole 150 connected to the back side of the mounting plate is provided on the bottom surface of the recess 110. Such a recess 110 can usually be provided at a position on the mounting plate where there is a large free space. In this embodiment, such recesses 110 are provided on the left and right sides of the switch mounting hole 120. The recess 110 is in a fully enclosed form to avoid circumferential glue overflow. A glue overflow hole 150 is left on the bottom surface of the recess 110. When there is too much adhesive 400, it plays a role in guiding the glue overflow to prevent the glue from overflowing inward and contaminating the display area of ​​the glass panel 200 and the switch assembly 300.

[0059] The switch installation hole 120 is provided with recessed portions 110 on all sides, and the installation plate body is connected to the glass panel 200 on all sides, and the connection is firm.

[0060] According to the specific shape of the mounting plate, the shape and position of the recess 110 can be different. In this embodiment, the recess 110 located on the upper side of the switch mounting hole 120, the recess 110 located on the lower side, the recess 110 located on the left side, and the recess 110 located on the right side are not connected to each other, that is, the recesses 110 at the four positions are independent of each other, not connected to each other, and are independently injected with glue, which has a higher injection accuracy. In other feasible schemes, at least two of the four recesses 110 located on the upper side of the switch mounting hole 120, the recess 110 located on the lower side, the recess 110 located on the left side, and the recess 110 located on the right side are interconnected, which can reduce the number of injections.

[0061] like Figure 1 As shown, the edge of the switch mounting hole 120 has a flange 130 folded toward the back side of the mounting plate body, and the flange 130 is located on the circumferential outer side of the switch assembly 300. The inner area of ​​the flange 130 is completely hollowed out to prevent the sheet metal from affecting the use of the switch assembly 300.

[0062] like Figure 7 As shown, the switch mounting hole 120 is in a rectangular shape, and the upper, lower, left, and right sides of the switch mounting hole 120 are all provided with flanges 130, and the flanges 130 on all sides are connected as a whole, completely surrounding the switch assembly 300, preventing condensed oil and condensed water from contacting the switch assembly 300, and playing a role in protecting the switch assembly 300. The inner circle projection surface length a6 of the flange 130 is slightly greater than the length c3 of the switch assembly 300, and the inner circle projection surface widths a4 and a5 of the flange 130 are slightly greater than the widths c1 and c2 of the switch assembly 300, meeting the minimum size installation requirements of the switch assembly 300. The length b3 of the switch hole 610 is slightly greater than the outer circle length a3 of the flange 130, and the widths b1 and b2 of the switch hole 610 are slightly greater than the outer circle widths a1 and a2 of the flange 130, meeting the minimum size installation requirements of the switch fixing bracket 100. Therefore, the material removal area of ​​the switch hole 610 is approximately equal to the outer ring projection area of ​​the switch assembly 300, which meets the minimum installation requirements of the switch assembly 300, reduces the material removal of the switch hole 610, and improves the strength of the smoke hood 600.

[0063] The flange 130 and the switch assembly 300 are provided with corresponding limiting structures to prevent the switch assembly 300 from moving relative to the flange 130. The limiting structures may be a slot 131 provided on the flange 130 and a claw 310 provided on the switch assembly 300. When the switch assembly 300 is placed inside the flange 130 along the depth direction, the claw 310 enters the slot 131 to prevent the switch assembly 300 from moving left and right. The widths a4 and a5 of the inner projection surface of the flange 130 are slightly larger than the widths c1 and c2 of the switch assembly 300, wherein the width a4 of the small end is ≈ c1, which serves to limit the upper and lower positions of the switch assembly 300.

[0064] like Figure 4 As shown, the switch fixing bracket 100 also includes a cover plate 500, and the cover plate 500 is detachably connected to the flange 130. Specifically, a protrusion 510 is provided on one side of the cover plate 500, and a plug hole is provided on the flange 130 on the same side; a screw hole 520 is provided on the other side of the cover plate 500, and a through hole is provided on the flange 130 on the same side. When installing, the protrusion 510 is first inserted into the plug hole, and then the cover plate 500 is pressed down, and after the screw hole 520 is aligned with the through hole, the two are locked with screws. The cover plate 500 is abutted against the back of the switch assembly 300, so that the switch assembly 300 is pressed between the cover plate 500 and the glass panel 200.

[0065] The range hood provided by the utility model includes the switch fixing bracket 100. Since the range hood provided by the utility model uses the switch fixing bracket 100, the range hood provided by the utility model also has the advantages of the switch fixing bracket 100.

[0066] The range hood further includes a switch assembly 300, which is installed in the switch installation hole 120. The switch assembly 300 has at least two functional modules, which realize different functions. The functional modules are both connected to signal transmission harnesses. An isolation rib 391 is provided in the switch assembly 300, which is used to separate signal transmission harnesses connected to different functional modules to avoid signal interference.

[0067] Specifically, the switch assembly 300 includes: a housing, a touch module, an expansion module and a second circuit board 340. The housing includes a box body 380 and a cover body 390, which can be assembled together.

[0068] The touch module includes a display screen 322 and a first circuit board 320. The display screen 322 is connected to the outer wall of the box body 380 and is bonded to the glass panel 200. The first circuit board 320 is connected to the inside of the box body 380. The function implemented by the expansion module is different from that of the touch module. In this embodiment, the expansion module may include a waving module 330, which executes corresponding instructions by collecting the user's waving action. The second circuit board 340 plays a summarizing role. The first circuit board 320 and the expansion module are both electrically connected to the signal input end of the second circuit board 340, and the signal output end of the second circuit board 340 is used to connect to the main controller of the kitchen appliance.

[0069] like Figure 6 - Fig. 9As shown, in order to reduce the length of the switch assembly 300 in the left-right direction, the first circuit board 320 and the second circuit board 340 are arranged in parallel and spaced apart from each other. At least a part of the second circuit board 340 has a projection on the plane toward the first circuit board 320 that falls on the first circuit board 320, that is, the two are arranged in an interlaced manner. Specifically, a support rib 350 and a support column 360 can be arranged on the box body 380. The support rib 350 is used to support the first circuit board 320, and the support column 360 supports the second circuit board 340. The height of the support column 360 is higher than the height of the support rib 350. Therefore, the second circuit board 340 can be placed above the first circuit board 320, and some areas of the left and right spaces can be overlapped, so that the overall length of the switch assembly 300 is reduced, and the size of the corresponding switch hole 610 on the smoke hood 600 can be reduced, which reduces the material removal area and increases the strength of the smoke hood 600.

[0070] like Fig.10 and Fig.12 As shown, the waving module 330 and the second circuit board 340 are connected via the first wiring harness 321, the display screen 322 and the first circuit board 320 are connected via the second wiring harness 331, and an isolation rib 391 is provided on the cover body 390. When the cover body 390 is combined with the box body 380, the isolation rib 391 separates the first wiring harness 321 and the second wiring harness 331.

[0071] Further, such as Fig.11 As shown, in order to avoid the disorder of the wire harness, a wire harness buckle 370 is further provided inside the box body 380, and the wire harness buckle 370 can tighten the signal transmission wire harness. In this embodiment, the wire harness buckle 370 is arranged close to the side wall of the box body 380, and its head has a guide arc, and the distance between the top of the wire harness buckle 370 and the side wall is greater than the distance between the bottom and the side wall, so that the wire harness is guided to enter the bottom of the wire harness buckle 370 through the gap between the side wall of the box body 380 and the wire harness buckle 370.

[0072] 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.
