Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly relates to an anti-deformation back panel structure and a range hood having the structure. Background Art

[0002] During the design process of a range hood, a smoke collecting hood back panel is assembled to facilitate the disassembly and assembly of internal parts and after-sales service. During the transportation of the range hood, since the back panel assembly uses low-cost materials such as 0.4 - 0.8 mm galvanized sheet, the back panel is often prone to denting, deformation, and damage during handling or dropping. When a user opens the product and finds it damaged, the product will be returned or complained about, which not only reduces the competitiveness of the product but also affects the brand influence.

[0003] In order to solve the problem that the 0.4 - 0.8 mm galvanized sheet is prone to deformation and damage during transportation or dropping, the existing method is to paste fixing glue on the back panel and strengthen the packaging structure. The strength of the back panel is enhanced by adding structures such as reinforcing ribs. However, the above methods not only greatly increase the overall cost of the machine, but also are extremely inconvenient in terms of assembly and after-sales during actual use.

[0004] In addition, in order to solve the problem of dropping deformation, the existing method is to press the galvanized sheet to enhance the strength of the back panel. However, due to unreasonable design, there is an obvious improvement effect on products with short-term transportation, low height, and light weight. However, there is no obvious improvement on products with long-distance transportation and heavy weight. Therefore, there is an urgent need to design a back panel structure that is not easily deformed even when dropped on products with long-distance transportation and heavy weight. Summary of the Invention

[0005] To solve the deficiencies of the existing technology, the present invention provides an anti-deformation back panel structure and a range hood having the structure.

[0006] The technical solution of the present invention is as follows:

[0007] An anti-deformation back panel structure includes a back panel body and mounting holes provided on the back panel body. An anti-deformation plate is provided at the upper end of the mounting holes, and auxiliary anti-deformation plates are provided at both ends of the anti-deformation plate. A first press-forming is provided in the circumferential direction of the anti-deformation plate, and the first press-forming provided at the position of the anti-deformation plate opposite to the mounting holes is in an arch rectangular structure. A second press-forming is provided on the auxiliary anti-deformation plate, and the cross-section of the second press-forming is in a rectangular structure.

[0008] Further, the mounting holes are arranged in 5 horizontally arranged at intervals.

[0009] Further, the anti-deformation plate and the back panel body are provided as an integral structure.

[0010] Furthermore, the front surface of the anti-deformation plate protrudes from the backplane body, and the back surface of the anti-deformation plate is recessed in the backplane body.

[0011] Furthermore, the anti-deformation plate is arranged in a strip structure, and an anti-deformation groove with an arch structure corresponding to the mounting hole is arranged at the bottom of the anti-deformation plate.

[0012] Furthermore, the auxiliary anti-deformation plate and the backplane body are arranged as an integral structure.

[0013] Furthermore, the auxiliary anti-deformation plate is arranged in a rectangular structure.

[0014] Furthermore, the width of the auxiliary anti-deformation plate is 2-4 mm smaller than the thickness of the wall of the air duct cover.

[0015] An oil fume extractor includes the above anti-deformation backplane structure.

[0016] The beneficial effects achieved by the present invention are as follows:

[0017] In the anti-deformation backplane structure of the present invention, an anti-deformation plate is arranged on the backplane body, and auxiliary anti-deformation plates are arranged on both sides of the anti-deformation plate. The arrangement of the auxiliary anti-deformation plates further avoids deformation during heavy mass, long-term transportation, and high-altitude drop.

[0018] The present invention sets a first press type on the anti-deformation plate. The first press type is designed in the shape of an arch rectangle, so that when the mounting screw exerts force to squeeze or pull the backplane body, the force can be better guided and the force is evenly distributed.

[0019] The backplane body of the present invention is provided with an auxiliary anti-deformation plate and a second press type. The width of the auxiliary anti-deformation plate is 2-4 mm larger than the wall thickness of the air duct cover, which fully ensures that the backplane does not deform. Description of the Drawings

[0026] To facilitate those skilled in the art to understand the present invention, the following combines the drawings to illustrate the specific implementation mode of the present invention.

[0027] As Figures 1 to 5 shown, the present invention provides an anti-deformation back plate structure and a range hood having this structure. The anti-deformation back plate structure includes a back plate body and mounting holes 1 provided on the back plate body. The mounting holes 1 are arranged horizontally at intervals in sequence, with 5 in number. Changing the existing 3 mounting holes 1 to 5 can prevent the hole pitch from being too large due to too few mounting holes 1, thereby preventing the back plate of the range hood from being deformed due to the force between the hole pitches during transportation or after falling.

[0028] An anti-deformation plate 2 is provided at the upper end of the mounting hole 1, and auxiliary anti-deformation plates 3 are provided at both ends of the anti-deformation plate 2. The anti-deformation plate 2 and the back plate body are set as an integral structure. The front of the anti-deformation plate 2 protrudes from the back plate body, and the back of the anti-deformation plate 2 is recessed from the back plate body. The anti-deformation plate 2 is set as a strip-shaped structure, and an anti-deformation groove in the shape of an arch corresponding to the mounting hole 1 is provided at the bottom of the anti-deformation plate 2. This can prevent the back plate structure from being deformed in products with heavy mass, long-term transportation, and high-altitude falling. A first press forming 21 is provided on the circumference of the anti-deformation plate 2, and the first press forming 21 provided at the position of the anti-deformation plate 2 opposite to the mounting hole 1 is an arch rectangular structure. This enables the mounting screws to better conduct force and be evenly stressed when squeezing or pulling the back plate body, and on the basis of 5 mounting screw holes, the corresponding first press forming 21 is added and connected together, fully ensuring that no deformation, wrinkle, damage, etc. occur in the anti-deformation plate 2 during the transportation, falling or vibration of the range hood.

[0029] The auxiliary anti-deformation plate 3 and the back plate body are set as an integral structure. The auxiliary anti-deformation plate 3 is set as a rectangular structure. A second press forming 31 is provided on the auxiliary anti-deformation plate 3, and the cross-section of the second press forming 31 is set as a rectangular structure. The width of the auxiliary anti-deformation plate 3 is 2 - 4 mm smaller than the thickness of the wall of the air duct cover 4. In this way, not only can the back plate body be hidden behind the range hood, but also the bottom of the air duct cover 4 can be completely wrapped at the bottom of the back plate body by using the second press forming 31 which is one press forming surface higher than the air duct cover 4, completely solving the problem of bumping between the back plate body and the air duct cover 4 during transportation and falling. Secondly, since the second press forming 31 is provided on the back plate body, part of the force forms a force in the direction of shear stress to squeeze the back plate body, so the second press forming 31 is provided here to fully solve the problem of shear stress extrusion.

[0030] The embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
