Description

Technical Field

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

[0002] There are generally two sealing protection measures for the display operation panel assembly of existing range hoods: one is to add a sealing sponge or a sealing pad between the display operation panel assembly and the glass panel. Since the fitting pressure of the display operation panel assembly itself is limited, there will be a poor sealing problem; the other is to add a switch cover outside the display operation panel assembly, which has the disadvantage of high cost.

[0003] In addition, when the plastic shell of the display operation panel assembly is deformed unevenly, the display screen of the display operation panel assembly cannot be attached to the glass panel due to the limited fitting pressure of the display operation panel assembly itself, which eventually leads to unclear display problems. Summary of the invention

[0004] The present invention aims to solve at least one of the problems existing in the existing related technologies to a certain extent. To this end, the present invention proposes a switch installation structure for a range hood, which has a simple structure and enhances the installation reliability of the switch component, so that the display screen of the switch component is close to the glass panel, thereby ensuring a better display effect.

[0005] According to the switch installation structure of a range hood provided above, it is implemented through the following technical solutions:

[0006] A switch mounting structure for a range hood comprises: a panel assembly, comprising a glass panel and a lining plate fixedly connected to the back of the glass panel, the lining plate being provided with a mounting opening; a switch assembly, passing through the mounting opening and connected to the lining plate; and at least one bracket assembly, clamped outside the switch assembly and connected to the lining plate, the bracket assembly pressing the switch assembly against the back of the glass panel.

[0008] In some embodiments, the reinforcing bracket includes a back plate and two side plates. The back plate is tightly pressed against the back surface of the switch assembly. The upper and lower ends of the back plate are bent forward respectively to form two side plates. The two side plates are located on the upper and lower outer sides of the switch assembly, and the free ends of the two side plates are detachably connected to the two mounting brackets respectively.

[0009] In some embodiments, the free end of the side plate is bent away from the switch assembly to form a convex edge. The convex edge is located behind the mounting bracket and is in clearance fit with the mounting bracket. The mounting bracket and the convex edge are detachably connected by a fastener.

[0010] In some embodiments, at least one bead arranged vertically is provided on the back plate, and the upper end and / or the lower end of the bead extends forward to the side plate.

[0011] In some embodiments, two mounting brackets located on the left and right outer sides of the mounting opening are fixedly connected to the back surface of the lining plate. Outer convex platforms extending outward are respectively provided at the left and right ends of the switch assembly, and the outer convex platforms are detachably connected to the corresponding mounting brackets.

[0012] In some embodiments, the mounting bracket is in any one of a "Z" shape, a "C" shape or an "Ω" shape.

DETAILED DESCRIPTION

[0024] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0025] refer to Figure 1-5 This embodiment provides a switch installation structure for a range hood, comprising a panel assembly (not shown in the figure), a switch assembly 2 and at least one bracket assembly (not shown in the figure), wherein the panel assembly comprises a glass panel 11 and a lining plate 12, the lining plate 12 is fixedly connected to the back of the glass panel 11 by bonding, and a mounting opening 121 is provided in the middle of the lining plate 12 in the left and right directions. The switch assembly 2 is inserted into the mounting opening 121 and connected to the lining plate 12, so that the switch assembly 2 is firmly and reliably mounted on the panel assembly.

[0026] In this embodiment, there is one bracket assembly, which is clamped outside the middle of the switch assembly 2 in the left-right direction and connected to the lining plate 12, and the bracket assembly presses the switch assembly 2 tightly against the back of the glass panel 11. In other embodiments, there may be two bracket assemblies, which are clamped outside the left and right ends of the switch assembly 2 respectively.

[0027] It can be seen that by placing the bracket assembly outside the switch assembly 2 and connecting it to the lining plate 12, it is beneficial to further enhance the installation reliability of the switch assembly, and secondly, the display screen 221 of the switch assembly 2 is closely attached to the glass panel 11 of the panel assembly, see Figure 2 To ensure better display effect, thus solving the problem that the display operation panel component (i.e., switch component) cannot be attached to the glass panel due to the uneven deformation of the plastic shell, which ultimately leads to unclear display.

[0028] refer to Figure 1-2 and Figure 5 Further, the bracket assembly includes a reinforcing bracket 3 and two mounting brackets 4, the two mounting brackets 4 are arranged on the upper and lower outer sides of the switch assembly 2, and the two mounting brackets 4 are fixedly connected to the back of the lining plate 12 by bonding or welding. The reinforcing bracket 3 is clamped outside the switch assembly 2, and the upper and lower ends of the reinforcing bracket 3 are detachably connected to the two mounting brackets 4 respectively. In this way, the switch assembly 2 is pressed and fitted to the back of the glass panel 11 through the cooperation of the reinforcing bracket 3 and the two mounting brackets 4, which can better ensure that the display screen 221 on the switch assembly 2 is in close contact with the glass panel 11, and the display effect is better.

[0029] Specifically, the reinforcing bracket 3 includes a back plate 31 and two side plates 32. The back plate 31 is arranged behind the switch assembly 2 and fits against the back of the switch assembly 2, and is used to press the switch assembly 2 against the panel assembly. The upper and lower ends of the back plate 31 are respectively bent forward to form two side plates 32. The two side plates 32 are located at the upper and lower outer sides of the switch assembly 2, and the free ends of the two side plates 32 are respectively detachably connected to the two mounting brackets 4.

[0030] In this embodiment, the side plate 32 is located behind the corresponding mounting bracket 4, and a gap H is left between the side plate 32 and the mounting bracket 4. During installation, the free end of the side plate 32 is detachably connected to the corresponding mounting bracket 4 through a fastener 5 (such as a screw), so that the reinforcing bracket 3 is stably and reliably detachably connected to the mounting bracket 4, and by adjusting the installation depth of the fastener 5, the size of the gap H between the side plate 32 and the mounting bracket 4 can be adjusted, thereby adjusting the degree of compression of the reinforcing bracket 3 on the switch assembly 2. In other embodiments, the free end of the side plate 32 and the corresponding mounting bracket 4 can be detachably connected through a snap-fit ​​structure, and the snap-fit ​​structure can include a positioning buckle and a plurality of snap positions. A plurality of snap positions arranged at intervals along the front-to-back direction are provided at the free end of the side plate 32, and a positioning buckle is provided on the mounting bracket 4. The positioning buckle can move between adjacent snap positions and can be matched with any snap position.

[0031] More specifically, the free end of the side plate 32 is bent in a direction away from the switch assembly 2 to form a convex edge 321. The convex edge 321 is located behind the mounting bracket 4 and is in clearance with the mounting bracket 4. A through hole 322 is provided on the convex edge 321 for the fastener 5 to pass through. A threaded hole 421 is provided at a position corresponding to the through hole 322 of the mounting bracket 4. During installation, the fastener 5 is passed through the through hole 322 of the convex edge 321 from back to front and then is threadedly connected to the hole wall of the threaded hole 421, so that the convex edge 321 can be detachably connected to the mounting bracket 4 through the fastener 5.

[0032] In order to increase the strength of the reinforcing bracket 3, at least one vertically arranged profile 311 is provided on the back plate 31, and the upper end and / or lower end of the profile 311 extends forward to the side plate 32. In this embodiment, the upper and lower ends of the profile 311 extend forward to the two side plates 32 respectively.

[0033] refer to Figure 1-5 Furthermore, two mounting brackets 4 located on the left and right outer sides of the mounting opening 121 are fixedly connected to the back of the lining plate 12, and outwardly extending external bosses 211 are respectively provided at the left and right ends of the switch assembly 2. The external bosses 211 are located behind the corresponding mounting brackets 4, and the external bosses 211 are detachably connected to the corresponding mounting brackets 4 by screws.

[0034] Specifically, the mounting bracket 4 is in any one of the shapes of "Ω", "Z", or "匚". In this embodiment, the mounting bracket 4 is in the shape of "Ω", including a front mounting edge 41 and a rear mounting edge 42. The rear mounting edge 42 is integrally formed by stamping backward from the middle of the length direction of the front mounting edge 41. A threaded hole 421 for mating with a fastener in threaded connection is provided on the rear mounting edge 42. The front mounting edge 41 (i.e., the front end of the mounting bracket 4) is fixedly connected to the back surface of the lining plate 12 by bonding or welding and is in contact with the lining plate 12. The rear mounting edge 42 (i.e., the rear end of the mounting bracket 4) is detachably connected to the reinforcing bracket 3 of the bracket assembly or the convex platform 21 of the switch assembly 2 by a fastener (such as a screw).

[0035] A positioning structure is provided between the front mounting edge 41 of the mounting bracket 4 and the lining plate 12. The positioning structure includes a positioning protrusion 123 and a positioning hole 411. Positioning holes 411 are respectively provided at opposite ends of the front mounting edge 41 of the mounting bracket 4. At the positions of the lining plate 12 corresponding to the positioning holes, a positioning protrusion 123 extending backward is integrally formed. The positioning protrusion 123 is inserted into the positioning hole of the front mounting edge 41. In this way, through the positioning structure, the installation of the mounting bracket 4 can be quickly positioned, and the mounting bracket 4 can be prevented from shifting relative to the lining plate 42, making it more convenient to fixedly connect the mounting bracket 4 to the back surface of the lining plate by bonding or welding.

[0036] Reference Figure 1-4 , Further, the switch assembly 2 includes a plastic housing 21 and a display panel 22. An opening 210 communicating with the inside of the plastic housing 21 is provided on the front surface of the plastic housing 21. Outer convex platforms 211 extending outward are integrally formed on the left and right sides of the plastic housing 21 respectively. The plastic housing 21 is detachably mounted on the lining plate 41 through the outer convex platforms 211. The display panel 22 is installed inside the plastic housing and has a display screen 221 extending forward. The display screen 221 sequentially passes through the opening 210 of the plastic housing 21 and the mounting opening 411 of the lining plate 41. Since the bracket assembly forms a pressing force on the switch assembly 2 after being connected to the lining plate 12, the front surface of the display screen 221 is closely attached to the back surface of the glass panel 11, ensuring the display effect.

[0037] In this embodiment, an annular groove 212 opening towards the lining plate 12 is provided on the outer periphery of the plastic housing 21 of the switch assembly 2. The annular groove 212 is arranged corresponding to the periphery of the mounting opening 121. Correspondingly, a flanging 122 extending backward is integrally formed on the periphery of the mounting opening 121. The flanging 122 is inserted into the annular groove 212 and is hermetically connected to the annular groove 212. In this way, through the cooperation of the flanging 122 and the annular groove 212, on the one hand, the switch assembly 2 is limited to prevent the switch assembly from shifting relative to the lining plate, and on the other hand, the sealing performance between the switch assembly 2 and the lining plate 12 is improved, thereby achieving the effects of oil prevention, smoke prevention, and water prevention.

[0038] Furthermore, the switch assembly 2 also includes a seal 23. The seal 23 is provided in the annular groove 212 and is located behind the flange 122. The flange 122 is sealed and connected to the annular groove 212 through the seal 23. In this way, the annular groove 212, the flange 122 and the seal 23 form a sealing barrier, so that the plastic housing 21 of the switch assembly 2 and the flange 122 on the liner 12 are in a close contact state, which plays a preliminary sealing role. Since the reinforcing bracket 3 squeezes the switch assembly 2, the seal 23 changes from a close contact state to an interference state, thereby playing a smoke-proof, oil-proof and waterproof sealing role for the switch assembly 2.

[0039] 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.
