Description

TECHNICAL FIELD

[0001] The utility model relates to an oil fume purification device, especially an oil fume extractor. BACKGROUND

[0002] The oil fume extractor has become one of the indispensable kitchen household electrical appliances in modern families.

[0003] The traditional oil fume extractor is generally designed with the switch installed behind the panel (glass, acrylic, etc.), and the outer surface of the panel has no key protrusion, which is convenient for cleaning. For example, the oil fume extractor disclosed in Chinese Patent No. 201810201489.7 includes a shell, a touch switch, and an indication panel. The touch switch and the indication panel are oppositely arranged and respectively located on the two sides of the shell. The indication panel is pasted on the surface of the shell, and the indication panel includes a rectangular glass panel.

[0004] The above-mentioned prior art generally uses double-sided adhesive or silicone adhesive to integrally bond and fix the panel. The space required for the turnover of the fume hood and the panel after bonding before production is large. Since the glass panel and the box type are fixed in a non-detachable manner, if the glass is damaged, the fume hood assembly adhered thereto needs to be disassembled and repaired as a whole, which is difficult to disassemble and repair, and the cost loss is also large. In addition, when the switch assembly needs to be repaired, the top plate covering the upper part of the box and other parts affecting the disassembly space such as the fan cover need to be disassembled, which is complicated, time-consuming and laborious.

[0005] In addition, the conventional switch assembly and glass panel fixing method are generally to bond a switch bracket on the glass panel first, and then fix the switch assembly on the panel bracket through screws. However, based on the actual waterproofing needs, the front side of the switch assembly is usually provided with an elastic sealing element (foam or silicone pad, etc.), and based on the error between the bracket mounting hole and the switch mounting hole, the glass panel will be deformed to a certain extent after the switch is installed, especially for the glass panel with a large length-width ratio, which will cause uneven gaps between the panel assembly and the fume hood after installation, affecting the overall aesthetic delicacy, and the degree of bending deformation will increase the risk of water vapor entering the interior to a certain extent.

[0043] Referring to Figures 1-5 , Figure 7 An extractor hood comprises a hood 1, a panel assembly 2 and a switch assembly 3. The hood 1 comprises a mounting plate 11 on the front side, and the mounting plate 11 is provided with a through hole 111. The panel assembly 2 comprises a panel 21, a first support 22 and a second support 22. The mounting plate 11 is a part of the integral hood 1, which is a flat plate, and the shape and size of the mounting plate 11 are adapted to the panel 21. Generally, the mounting plate 11 and the panel 21 are both long strips. The panel 21 has a front side facing the user and a back side away from the user. The back side of the panel 21 is mounted to the mounting plate 11, and the back side can be tightly attached to the mounting plate 11, i.e. the panel 21 is mounted to the front side (the side facing the user) of the mounting plate 11, and the first support 22 and the second support 22 can pass through the mounting plate 11 from front to back. The switch assembly 3 is arranged on the back side of the panel 21 and extends to the back side of the mounting plate 11 through the through hole 111, so as to enter the inside of the hood 1.

[0044] The panel 21 is generally a glass panel. The number of the first support 22 can be one or at least two. When the number of the first support 22 is at least two, the first supports 22 are arranged at intervals along the length direction of the panel 21 (the left-right direction of the extractor hood in the mounted state). The first support 22 is bonded to the side of the panel 21 facing the mounting plate 11. The first support 22 comprises a first support body 221 and a clamping jaw 222 arranged on the first support body 221. The first support body 221 is generally a flat plate as a bonding surface for bonding to the panel 21, and the clamping jaw 222 extends from the first support body 221 to the mounting plate 11. In this embodiment, preferably, the clamping jaw 222 is formed at each of the upper end and the lower end of the first support body 221, and the upper and lower clamping jaws 222 can be symmetrically arranged. The clamping jaw 222 can be horizontally arranged in an L shape, so as to be assembled with the mounting plate 11 along the left-right direction of the extractor hood when the panel 21 is mounted. The mounting plate 11 is provided with a clamping groove 112, and the clamping jaw 222 of the first support 22 can pass through the clamping groove 112 to be clamped and fixed with the mounting plate 11.

[0045] The second bracket 23 is arranged adjacent to the switch assembly 3 in the left-right direction of the range hood, and includes a second bracket body 231, a first folded edge 232, and a second folded edge 233. The second bracket body 231 is substantially flat to serve as an adhesive surface for bonding with the panel 21. The first folded edge 232 is formed on a side of the second bracket body 231 away from the switch assembly 3, and is bent from the second bracket body 231 toward the mounting plate 11, so as to pass through the through hole 111. The second folded edge 233 is transversely bent from a lower end of the first folded edge 232 away from the switch assembly 3. In this embodiment, the first folded edge 232 extends vertically, and the second folded edge 233 extends horizontally, both in an L shape. The second folded edge 233 is provided with a first fixing hole 234, which is a flange hole, and can achieve multiple detachments of the panel assembly 2 and the smoke collecting hood 1.

[0046] The first bracket 22 and the second bracket 23 are preferably integrally formed.

[0047] The smoke collecting hood 1 further includes a fixed edge 12 fixed with the second bracket 23. The fixed edge 12 includes a third folded edge 121 and a fourth folded edge 122. The third folded edge 121 is formed on a side edge of the mounting plate 11 located at the through hole 111, and extends in the same direction as the first folded edge 232. The fourth folded edge 122 is transversely bent from a lower end of the third folded edge 121 away from the switch assembly 3, and extends in the same direction as the second folded edge 233. In the mounted state, the first folded edge 232 is adjacent to the third folded edge 121, and the second folded edge 233 is adjacent to the fourth folded edge 122. Preferably, the first folded edge 232 is tightly attached to a side of the third folded edge 121 close to the switch assembly 3, and the second folded edge 233 is tightly attached below the fourth folded edge 122. The fourth folded edge 122 is provided with a second fixing hole 123. The second bracket 23 and the fixed edge 12 can be fixed (detachably connected) by a fastener such as a screw passing through the first fixing hole 234 and the second fixing hole 123, so as to further limit and fix the panel 21 and the mounting plate 11.

[0048] In the installation, the first bracket 22 of the bonded control panel assembly (the panel assembly 2 and the switch assembly 3) is first aligned with the corresponding clamping groove 112 on the mounting plate 11 of the smoke collecting hood 1, and is translated backward. The clamping jaw 222 of the first bracket 22 gradually passes through the clamping groove 112, and after the inner side of the panel 21 is pushed to contact the surface of the mounting plate 11 of the smoke collecting hood 1, the first bracket 22 is slid to the side where it is locked, until the clamping jaw 222 is limited, i.e., the bent part of the L-shaped clamping jaw 222 abuts against the edge of the clamping groove 112, so as to limit the forward and backward movement of the control panel assembly. The tightness of the left-right movement is controlled by limiting the relative gap between the first bracket 22 and the clamping groove 112 (statically working without being separated in the left-right direction).

[0049] The installation hole 13 for the lighting device 4 can be provided at a position below the mounting plate 11 and at the rear side of the mounting plate 11, see Figure 3 、 Figure 9 and Figure 10 The two installation holes are above the installation hole 13. Through the space of the installation hole 13, the second support 23 of the control panel assembly installed in place can be fixed to the corresponding folded edge of the fume hood 1 by a screw and a tool (such as a screwdriver), so as to realize effective locking and fixing of the control panel assembly and the fume hood 1, and ensure that the panel assembly does not slip off under the working conditions of machine movement drop and user wiping. Subsequent installation of the lighting device 4 to the installation hole 13 can cover the panel assembly installation features, avoid the exposure of screws and other factors affecting the appearance, and improve the overall delicacy of the product; when maintenance is needed, reverse operation can be performed.

[0050] Referring to Figure 6 and Figure 8 , the switch assembly 3 includes a switch base 31, a circuit board 32, and a switch upper cover 33. The switch base 31 is fixed to the panel 21 and can be directly fixed to the panel 21 by adhesive bonding. The two are not detachable (except for destructive disassembly such as scraping glue). The side of the switch base 31 away from the panel 21 is open to facilitate installation of the circuit board 32. The switch upper cover 33 covers the open side of the switch base 31, and the two are detachably connected, such as by screws. The circuit board 32 is detachably installed in the switch base 31, such as by a buckle or a screw. The switch upper cover 33 encloses the circuit board 32 in the switch base 31, and the switch cover plate 33 can be removed when the switch needs to be repaired.

[0051] In this embodiment, the switch support is no longer used, but the switch base 31 is directly bonded to the back of the panel 21, reducing the deformation caused by the bonding surface and the installation error of the two components, and also reducing the compression deformation of the sealing element. The switch assembly 3 only acts on a local area of the panel 21, and the overall deformation of the switch assembly 3 is smaller than that of the panel 21, which does not cause overall bending deformation, ensuring the overall flatness requirement, and the adhesive scheme can meet the waterproof requirement of the switch assembly 3.
