Description

Technical Field

[0001] This invention relates to a range hood, and more particularly to a display panel mounting structure and a range hood using the same structure. Background Technology

[0002] Many existing home appliances use touchscreens, with the control panel (display panel) located on the back of a glass panel. There are typically two installation methods for the control panel: one is to attach the control panel to the glass panel, which is more complex and requires higher manufacturing standards; the other is to integrate the control panel and glass panel as a single unit, which makes after-sales maintenance and disassembly more inconvenient. Therefore, further improvements are needed to the existing display panel installation structure. Summary of the Invention

[0003] The first technical problem to be solved by the present invention is to provide a display panel mounting structure that is simple in structure and easy to disassemble, in view of the above-mentioned existing technology.

[0004] The second technical problem to be solved by the present invention is to provide a range hood with a touch-sensitive display panel that can avoid oil fume contamination of the display panel, in light of the above-mentioned existing technology.

[0005] The technical solution adopted by the present invention to solve the first technical problem mentioned above is as follows: The display panel mounting structure includes a fixing box and a display panel mounted on the fixing box, characterized in that: it further includes a fixing strip, the fixing box is provided with a snap-fit ​​part, the snap-fit ​​part is provided with an elastic element, the fixing strip has a snap-fit ​​foot that cooperates with the snap-fit ​​part, the display panel has a through hole corresponding to the snap-fit ​​part, the fixing strip is located on the outside of the display panel, the snap-fit ​​foot of the fixing strip passes through the through hole and extends into the snap-fit ​​part to abut against the elastic element, under the elastic force of the elastic element, the snap-fit ​​foot has the tendency to move outward and drive the display panel to move outward until it abuts against the fixing strip.

[0006] In order to enable the elastic foot to drive the display panel to move outward, the side of the foot is provided with a hook, the hook is located on the inside of the display panel, and under the action of the elastic element, the hook is snapped onto the inside of the display panel.

[0007] In order to prevent the open hook head from interfering with the locking part, the side wall of the locking part has a notch to avoid the hook. When the locking foot is engaged in the locking part, the head of the hook is located in the notch.

[0008] The elastic element can have various structures. Preferably, the elastic element is a spring, with the inner end of the spring abutting against the bottom of the snap-fit ​​portion and the outer end of the spring abutting against the bottom of the snap-fit ​​foot.

[0009] To ensure a more secure installation of the display panel, the fixing box is square, with the snap-fit ​​parts distributed on two opposite sides of the fixing box, and the snap-fit ​​parts on each side are spaced apart. Correspondingly, there are two fixing strips, which are arranged on the two opposite sides of the fixing box, and the fixing strips are provided with snap-fit ​​feet that correspond one-to-one with the snap-fit ​​parts.

[0010] Further preferred, each side has 3 to 6 locking parts, and correspondingly, each fixing strip has 3 to 6 locking feet.

[0011] In order to keep the outer side of the display panel flush or approximately flush with the outer side of the fixing strip, a mounting step lower than the outer side of the display panel is formed on the display panel at the position corresponding to the fixing strip. The through hole is opened on the mounting step. The fixing strip is disposed on the mounting step, and the outer side of the fixing strip is flush or approximately flush with the outer side of the display panel.

[0012] To ensure a tight seal between the mounting box and the external mounting surface, a sealing ring is installed around the perimeter of the mounting box. This sealing ring prevents external contaminants from entering the mounting box and contaminating the display panel.

[0013] In order to install the fixing box, mounting holes for mounting on the fixing bracket are provided on the outer periphery of the fixing box.

[0014] The technical solution adopted by the present invention to solve the second technical problem mentioned above is that the range hood includes an upper housing assembly and a lower cavity assembly installed below the upper housing assembly. The lower cavity assembly includes a display panel, and the fixing box is provided on the back of the display panel. Under the action of the elastic member, the display panel abuts against the back of the display panel.

[0015] Compared with the prior art, the advantages of the present invention are as follows: the fixing box of the display panel mounting structure is provided with a snap-fit ​​part, and the fixing strip has a snap-fit ​​foot that cooperates with the snap-fit ​​part. When the snap-fit ​​foot of the fixing strip passes through the through hole of the display panel and extends into the snap-fit ​​part to abut against the elastic member, under the elastic force of the elastic member, the snap-fit ​​foot tends to move outward and drive the display panel to move outward until it abuts against the fixing strip. This mounting structure is not only simple in structure, but also very convenient to disassemble. After the range hood adopts this structure, the display panel can be pressed tightly against the back of the glass display panel to ensure touch sensitivity. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 5 As shown, the display panel mounting structure of this embodiment includes components such as a fixing box 1, a display panel 2, a fixing strip 3, a spring 4, and a sealing ring 5.

[0024] The fixing box 1 is square-shaped, and a mounting cavity 14 is formed inside the fixing box 1. A bracket portion 11 is provided inside the mounting cavity 14, and the snap-fit ​​portions 11 are distributed on two opposite sides of the fixing box 1. In this embodiment, each side of the fixing box 1 has four spaced-apart snap-fit ​​portions 11. The snap-fit ​​portions 11 are hollow inside, and a spring 4 is installed inside each snap-fit ​​portion 11. Notches 12 are formed on the side walls of the snap-fit ​​portions 11. In addition, the outer periphery of the fixing box 1 has mounting holes 13 for mounting on a fixing bracket (not shown in the figure). A sealing ring 5 is installed around the periphery of the fixing box 1.

[0025] The display panel 2 can also be called the control panel. The display panel 2 has a square structure that matches the shape of the fixing box 1. The display panel 2 is located in the mounting cavity 14. The two sides of the display panel 2 are formed with mounting steps 22 that are lower than the outer side of the display panel. Through holes 21 corresponding to the snap-fit ​​parts 11 are opened on the mounting steps 22, that is, four through holes 21 are opened on each side of the mounting steps 22.

[0026] There are two fixing strips 3, which are correspondingly arranged on two opposite sides of the fixing box 1. Each fixing strip 3 has a locking foot 31 that corresponds one-to-one with the locking part 11, that is, each fixing strip 3 has four locking feet 31. The two sides of the locking feet 31 are respectively provided with hooks 32.

[0027] When installing the display panel 2, first place the spring 4 inside the latching part 11, and place the display panel 2 in the appropriate position in the mounting cavity 14 of the fixing box 1, so that the through hole 21 of the display panel 2 is aligned with the latching part 11 of the fixing box 1; then, place the fixing strip 3 on the corresponding mounting step 22 of the display panel 2, press the fixing strip 3 inward, so that the latch 31 of the fixing strip 3 passes through the through hole 21 of the display panel 2 and inserts into the corresponding latching part 11, until the latch 31 is fully inserted and abuts against the spring 4 inside the latching part 11; finally, release the fixing strip 3, and the latch 31 springs outward under the elastic force of the spring 4, and the latch hook 32 of the latch 31 is upside down on the inner side of the display panel 2, thereby keeping the display panel 2 with an outward movement tendency until the mounting step 22 of the display panel 2 abuts against the fixing strip 3.

[0028] like Figure 5 As shown, after the display panel 2 is installed, the head of the hook 32 is located in the notch 12 of the latching part 11 and abuts against the inner side of the display panel 2. The outer side of the fixing strip 3 is flush with or approximately flush with the outer side of the display panel 2.

[0029] like Figure 6 As shown, the range hood in this embodiment includes an upper housing assembly 6 and a lower cavity assembly 7 installed below the upper housing assembly. The upper housing assembly 6 includes a range hood fan (not shown in the figure), and the lower cavity assembly 7 forms a smoke inlet chamber that communicates with the range hood fan. For an air-conditioning type range hood, the air conditioning component is installed inside the upper housing assembly 6.

[0030] The lower cavity assembly 7 includes a display panel 71, which is typically made of glass. A mounting bracket (not shown) is located on the back of the display panel 71. Both the display panel 71 and the mounting box 1 are mounted on the mounting bracket, and the mounting box 1 is sealed to the back of the display panel 71 by a sealing ring 5 to prevent oil fumes from entering the mounting cavity 14 of the mounting box 1 and contaminating the display panel 2. Additionally, the spring 4 allows the display panel 2 to adhere to the back of the display panel 71, ensuring touch sensitivity.
