Description

Technical Field

[0001] The utility model relates to the technical field of range hood installation, and is a mounting structure for a range hood. Background Art

[0002] Range hoods are essential appliances for daily cooking and extracting fumes. To achieve a high-end look, today's kitchens often feature integrated cabinets and range hoods. Installation, maintenance, removal, and reinstallation of range hoods often require matching them with the cabinets. Traditional range hoods are typically secured to the wall using hooks installed on the back.

[0003] In order to facilitate hanging the range hood on the hook, a groove with an up and down stroke needs to be provided on the hook to prevent the range hood from falling forward. The range hood needs to be placed in two different positions with an up and down difference during the entire installation process. This will make it difficult to install the range hood flush with the cabinet that has been installed in advance, resulting in an obvious gap between the bottom of the cabinet and the smoke hood of the range hood, which makes it easy for dirt to accumulate in the gap and difficult to clean, and also affects the appearance.

[0004] There are also some installation methods in the prior art that can avoid obvious gaps in the range hood after installation, such as the "A hanging bracket for range hood" disclosed in the Chinese utility model patent application with application number 202120383372.2 (authorization announcement number CN214275883U), which includes a range hood, a hood fixing plate, and an anti-cracking reinforcement plate fixed on the upper end of one side of the range hood. The anti-cracking reinforcement plate of the range hood fixing plate is evenly distributed on the side close to the range hood, and there are also a range hood bracket, a range hood fixing plate, and a range hood bracket. The range hood bracket includes a bracket fixing plate and a range hood fixing plate. Through the mutual cooperation between the range hood and the range hood bracket, the range hood can be easily installed and disassembled, avoiding the gap between the range hood and the wall. However, only the gap between the range hood and the wall is reduced here, and there is no significant improvement in the coordination structure between the range hood and the cabinet.

[0005] Therefore, how to provide a more convenient installation method to achieve seamless installation between the range hood and the cabinet, and to adapt well to the different sizes of openings opened by carpenters or cabinet companies, and to utilize the original openings when replacing the range hood without having to drill new holes in the user's home, is a problem that technical personnel in this field urgently need to solve.

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] Figures 1 to 3 The structure diagram of Example 1 is shown. The range hood installation structure in Example 1 mainly includes a fan frame 1, a fume hood 2, a cabinet 3 and a mounting bracket 4.

[0026] refer to Figures 1 to 3 As shown, the cabinet 3 is located above the smoke hood 2. An opening 3b is provided on the bottom plate 3a of the cabinet 3 for the fan rack 1 to enter from the bottom up. The mounting bracket 4 is provided on two opposite sides of the fan rack 1. The mounting bracket 4 includes a connecting portion 4a laterally connected to the side of the fan rack 1 and a supporting portion 4b extending downward from the connecting portion 4a. The supporting portion 4b has a supporting piece 4b1 extending obliquely downward toward the outside of the fan rack 1 and having a certain elasticity. The fan rack 1 penetrates the opening 3b from the bottom up. In state b, the support piece 4b1 can deform inwardly under its own elastic action so that the mounting bracket 4 can be synchronously passed up to the inside of the cabinet along with the fan frame 1. After passing up to the inside of the cabinet 3, the support piece 4b1 can be reset outwardly and supported on the bottom plate 3a of the cabinet 3 to fix the fan frame 1 on the cabinet 3. By gently pushing the fan frame 1 upward into the opening 3b, the entire range hood can be fixed to the cabinet 3 through the mounting bracket 4, and the smoke hood 2 and the cabinet 3 can be fixed to each other and fit together.

[0027] In order to optimize the overall structure of the mounting bracket 4, so that the support piece 4b1 can be better connected to the connecting portion 4a, and the support piece 4b1 can better form elasticity under external force, refer to Figure 3As shown, the support portion 4b in embodiment 1 further includes a support plate 4b2 extending vertically downward from the first end of the connecting portion 4a, and the support piece 4b1 extends obliquely from the bottom of the support plate 4b2 toward the outside of the wind turbine frame 1 and is integrally formed.

[0028] Secondly, in order to better install the mounting bracket 4 on the side of the wind rack 1, refer to Figure 3 As shown, in Example 1, the second end portion of the connecting portion 4a is formed with a mounting plate 4a1 extending vertically for connection to the side of the fan frame 1. The mounting plate 4a1 is provided with a mounting hole 4a3 for a first fastening screw 4a2 to pass through. The first fastening screw 4a2 can be used to fix the mounting bracket 4 to the mounting bracket 4 of the range hood at a set position.

[0029] In addition, in order to enhance the support strength of the mounting bracket 4, refer to Figure 3 As shown, the connecting portion 4a in Example 1 is in the form of a plate, and ribs 4a4 extending downward to enhance the lateral strength are formed on the two side edges of the connecting portion 4a. The extension of the ribs 4a4 can greatly enhance the lateral support strength of the mounting bracket 4.

[0030] In addition, in embodiment 1, in order to facilitate the manufacture of the mounting bracket 4 and save costs, the mounting plate 4a1, the connecting portion 4a, the supporting plate 4b2 and the supporting piece 4b1 are formed as an integral part.

[0031] Example 2

[0032] In order to make the length of the connecting portion adjustable, another embodiment of the mounting bracket 4 is provided. Figure 4 and Figure 6 As shown, in Example 2, the connecting portion 4a includes a first connecting portion 41 and a second connecting portion 42. The second connecting portion 42 can move relative to the first connecting portion 41 in the transverse direction to achieve length adjustment of the connecting portion 4a. The mounting plate 4a1 is connected to the first connecting portion 41, and the support plate 4b2 is connected to the second connecting portion 42. A positioning device 43 is also provided between the first connecting portion 41 and the second connecting portion 42, which can move the second connecting portion 42 to a set position and then fix it.

[0033] refer to Figure 5 As shown, in Example 2, in order to make the lateral movement of the first connecting part 41 and the second connecting part 42 more stable and precise, a laterally extending guide groove 41a is formed on the first connecting part 41, and a guide wall 42a that can be adapted in the guide groove 41a is formed on the second connecting part 42. The first connecting part 41 and the second connecting part 42 can achieve lateral relative movement under the guidance cooperation of the guide wall 42a of the guide groove 41a.

[0034] Moreover, the first connection portion 41 and the second connection portion 42 are both plate-shaped. The guide groove 41 a is formed by folding two side edges of the first connection portion 41 , and the guide wall 42 a is formed by folding two side edges of the second connection portion 42 .

[0035] refer to Figure 5 and Figure 6 As shown, in Example 2, the positioning device 43 includes a second fastening screw 43a, and the first connecting part 41 is provided with a screw hole 41b that passes through the screw hole 41b from top to bottom and is adapted for the second fastening screw 43a. After the second fastening screw 43a passes through the screw hole 41b from top to bottom, it can press against the second connecting part 42 to fix the first connecting part 41 and the second connecting part 42 to each other.

[0036] In Examples 1 and 2, in order to enable the mounting bracket 4 to better fix the range hood on the cabinet 3, the mounting bracket 4 is provided with at least two mounting holes 4a3 and arranged at intervals along the transverse direction of the mounting plate 4a1. As shown in the figure, there are two mounting holes 4a3.

[0037] Additional explanation is required here: in Example 1 and Example 2, by respectively providing mounting brackets 4 on two opposite sides of the fan rack 1, and forming the mounting bracket 4 with a connecting portion 4a laterally connected to the side of the fan rack 1 and a supporting portion 4b extending downward from the connecting portion, the supporting portion 4b is also formed with a supporting piece 4b1 extending obliquely downward. When the fan rack 1 is inserted into the opening 3b from bottom to top, the supporting piece 4b1 can deform inwardly under its own elastic action so that the mounting bracket 4 can follow the fan rack 1 and pass into the interior of the cabinet 3 synchronously. After passing into the interior of the cabinet 3, the supporting piece 4b1 can be reset outward so that the mounting bracket 4 is supported on the bottom plate 3a of the cabinet 3, and finally the fan rack 1 is quickly and conveniently fixed to the cabinet 3. Since we have measured the position and installed the mounting bracket 4 at the appropriate position on the side of the fan frame 1 in advance, we can quickly install it by accurately pushing the fan frame 1 of the range hood upward into the opening 3b opened on the bottom plate 3a of the kitchen cabinet 3, so that the top of the smoke hood 2 of the range hood can be completely fitted with the bottom of the kitchen cabinet 3 to achieve a seamless connection, avoiding the gap caused by two different positions with an upper and lower difference when the range hood is installed in the prior art, and can also well adapt the fan frame 1 of the range hood to the opening 3b originally opened by the carpenter or cabinet company, so that when the range hood is replaced and repaired, the original opening 3b can be used without drilling a new hole in the user's home. Since there is no need to set a hanging bracket on the back of the range hood, it can also effectively avoid the obvious gap between the back of the range hood and the wall.
