Description

Technical Field

[0001] The utility model relates to an oil fume purification device, in particular to a range hood. Background Art

[0002] With the increasing variety of the forms of range hoods, there are more and more changes in the appearance and movement forms of traditional top-mounted range hoods. Nowadays, many top-mounted range hoods are installed with a back panel at the upper rear side of the smoke collecting hood to improve the overall aesthetics and fullness of the machine. For example, a range hood disclosed in the application number 202330177640.X of the applicant.

[0003] The traditional form of installing the complete machine at the user's home poses challenges to the transportation and installation safety of the back panel glass and places higher requirements on the capabilities of installation technicians. If the back panel assembly is installed on the production line, the production efficiency will be reduced; if the machine is installed at the user's home with the existing back panel structure, it is easy for the back panel glass to be scratched due to the inclination angle, resulting in losses. In addition, the weight of the back panel assembly will increase the burden on the installation technicians.

[0004] Therefore, a convenient and safe back panel installation method that can be installed at the user's home is needed. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a range hood aiming at the deficiencies of the above-mentioned existing technologies, so as to improve the convenience of installing the range hood including the back panel assembly.

[0006] The technical solution adopted by the utility model to solve the above technical problems is as follows: A range hood includes a box body, a smoke collecting hood arranged at the bottom of the box body, and back panel assemblies arranged on the left and right sides of the box body. The box body includes side plates on the left and right sides. The back panel assembly includes a back panel glass. It is characterized in that:

[0007] The back panel assembly further includes a rear plate. The rear plate includes a plate body and a convex portion extending downward from the bottom of the plate body. The plate body is arranged on the back of the back panel glass and matches the back panel glass. The convex portion is located below the top surface of the smoke collecting hood. A screw bushing assembly is arranged at the rear side of the smoke collecting hood. A support groove is formed by the bottom surface of the convex portion being recessed upward. The support groove cooperates with the screw bushing assembly so that the convex portion is supported on the screw bushing assembly.

[0008] The backplate assembly is independent of the range hood body, so it can have its own separate packaging space, improving the safety during transportation. Through the cooperation of the convex part and the screw bushing assembly, the backplate assembly can be placed from top to bottom during installation, reducing the burden on the installation technician caused by the weight of the backplate assembly and improving the convenience of installing the range hood with the backplate assembly. In addition, the cooperation of the convex part and the screw bushing assembly can limit the offset of the backplate assembly in the left-right direction, avoiding the risk of backplate glass breakage caused by the offset.

[0009] Preferably, the support groove is semi-circular, the screw bushing assembly includes a screw and a bushing arranged on the outer periphery of the rod part of the screw, and the peripheral wall of the support groove wraps around the outer periphery of the bushing.

[0010] Preferably, to increase the stability of the support, there are two convex parts arranged at intervals left and right, and correspondingly, there are two groups of screw bushing assemblies arranged at intervals left and right.

[0011] Furthermore, the rear plate further includes an installation part formed at the top of the plate body. The installation part is arranged at the position corresponding to the corresponding side plate of the plate body, extends forward from the position of the plate body, and is fixedly combined with the corresponding side plate. The cooperation between the installation part and the side plate can limit the offset of the backplate assembly in the vertical direction and the rotational direction, reducing the risk of scratching the backplate glass during installation.

[0012] Furthermore, a sunk platform is formed at the position where the side plate cooperates with the installation part, and the installation part is embedded at the sunk platform to prevent the installation part from protruding above other parts of the side plate.

[0013] Furthermore, the backplate glass is in close contact with the corresponding side plate, the plate body extends beyond the side plate towards the middle and partially overlaps with the side plate, and the installation part is formed at the overlapping part of the plate body and the side plate, so as to facilitate the formation of the installation part corresponding to the side plate.

[0014] Furthermore, an installation groove is formed at the rear end of the top of the smoke collecting hood. The installation groove is formed by recessing downward from the top surface of the smoke collecting hood, and the bottom of the backplate glass is inserted into the installation groove. Through the setting of the installation groove, the overall appearance of the machine can be more integrated, and there will be no phenomenon of light leakage due to the slight inclination or gap of the backplate assembly.

[0015] Furthermore, the backplate assembly further includes an elastic cushion strip. The cushion strip is placed in the installation groove and supports the bottom of the backplate glass, thereby facilitating the reliable and stable installation of the bottom of the backplate glass in the installation groove.

[0016] Compared with the prior art, the advantages of the present utility model are as follows: The backplate assembly is independent of the range hood body, so it can have its own separate packaging space, improving the safety during transportation; through the cooperation of the convex portion and the screw bushing assembly, the backplate assembly can be placed from top to bottom during installation, reducing the burden on the installation technician caused by the weight of the backplate assembly and improving the convenience of installing the range hood with the backplate assembly; in addition, the cooperation of the convex portion and the screw bushing assembly can limit the offset of the backplate assembly in the left - right direction, avoiding the risk of backplate glass breakage caused by the offset; through the cooperation of the installation portion and the side plate, the offset of the backplate assembly in the vertical direction and the rotational direction can be limited, reducing the risk of scratching the backplate glass during installation; through the installation groove formed on the smoke collecting hood and the cooperation with the bottom of the backplate glass, the overall machine can have a more integrated appearance, and there will be no light leakage phenomenon caused by the slight inclination or gap of the backplate assembly.

[0026] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions.

[0027] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the disclosed embodiments of the present utility model can be arranged in different directions, these terms indicating directions should only be regarded as illustrative and not as restrictive. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity. In addition, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0028] See Figures 1 to 5 , an oil fume suction machine, which includes a box body 1 and a smoke collecting hood 2 arranged at the bottom of the box body 1. The fan system (not shown) that serves as the power of the oil fume suction machine can be arranged inside the box body 1, or another box body communicating with the box body 1 can be provided for arranging the fan system.

[0029] The width of the box body 1 in the left-right direction is smaller than that of the smoke collecting hood 2. Therefore, a set of back plate assemblies 3 are respectively arranged on the left and right sides of the box body 1. The height of the back plate assemblies 3 is approximately equal to that of the box body 1. The total width of the two sets of back plate assemblies 3 and the box body 1 is approximately equal to the width of the smoke collecting hood 2. The two sets of back plate assemblies 3 have the same structure and are symmetrically arranged.

[0030] The back plate assemblies 3 are respectively installed on the box body 1 and the smoke collecting hood 2. Specifically, each set of back plate assemblies 3 includes a back plate glass 31, a back plate 32, and a cushion strip 33. The back plate glass 31 is arranged on the back plate 32. Most of the back plate 32 is located on the back surface of the back plate glass 31 (i.e., the surface facing the rear and away from the user in the installed state). Thus, it is installed on the box body 1 and the smoke collecting hood 2 through the back plate 32, and the back plate glass 31 is protected by arranging the back plate 32.

[0031] The cabinet 1 includes side plates 11 near the left and right sides. The rear plate 32 includes a plate body 321 whose size and shape match those of the back panel glass 31. The plate body 321 is located on the back side of the back panel glass 31. The back panel glass 31 is in close contact with the side plates 11, while the plate body 321 can slightly extend beyond the side plates 11 towards the middle to form a mounting portion 322 corresponding to the side plates 11 as described below. That is, for the right back panel assembly 3, the left end of its rear plate 32 can be located on the left side of the right side plate 11, and for the left back panel assembly 3, the right end of its rear plate 32 can be located on the right side of the left side plate 11. A mounting portion 322 is formed at the top of the plate body 321. The mounting portion 322 is provided at a position corresponding to the respective side plate 11 on the plate body 321, that is, at the overlapping portion of the plate body 321 and the side plate 11. This overlapping portion is located at the rear side of the side plate 11. The mounting portion 322 extends forward from the position of the plate body 321. Thus, the mounting portion 322 can cooperate with the side plate 11. During installation, the mounting portion 322 is located at the top of the side plate 11, and the two can be fixed by screws. A counterbore 111 can be formed at the position where the side plate 11 cooperates with the mounting portion 322. Thus, the mounting portion 322 can be embedded at the counterbore 111 during installation so that the mounting portion 322 does not protrude significantly higher than other positions at the top of the side plate 11 after installation, avoiding affecting the overall structure of the cabinet 1.

[0032] See Figure 3 、 Figures 6 to 9 At the rear side end of the top of the smoke collecting hood 2, a mounting groove 21 is formed. The mounting groove 21 is formed by the depression of the top surface of the smoke collecting hood 2 downward. The mounting groove 21 extends in the left - right direction and is used for inserting the back panel glass 31. The gasket 33 of the back panel assembly 3 is placed in the mounting groove 21 and supports the bottom of the back panel glass 31. The gasket 33 has a certain elasticity to enable the reliable installation of the back panel glass 31. Through the setting of the mounting groove 21, the overall appearance of the whole machine can be more integrated, and there will be no phenomenon of light leakage due to the slight inclination or gap of the back panel assembly 3.

[0033] The rear plate 32 further includes a protruding portion 324 extending downward from the bottom of the plate body 321. The protruding portion 324 is located below the top surface of the smoke collecting hood 2 and at the rear side of the mounting groove 21. A screw bushing assembly 22 is provided at the rear side of the smoke collecting hood 2 and penetrates below the mounting groove 21. A support groove 3241 is formed by the upward depression of the bottom surface of the protruding portion 324. The protruding portion 324 supports on the screw bushing assembly 22. The support groove 3241 is semi - circular, and thus can cooperate with the screw bushing assembly 22. The screw bushing assembly 22 includes a screw 221 and a bushing 222 provided on the outer periphery of the rod portion of the screw 221. The peripheral wall of the support groove 3241 wraps around the outer periphery of the bushing 222. The screw bushing assembly 22 can have two groups and is arranged at intervals left and right. The number and position of the protruding portions 324 respectively match those of the screw bushing assembly 22.

[0034] Thus, through the cooperation of the convex portion 324 and the screw bushing assembly 22, the offset of the back panel assembly 3 in the left-right direction can be restricted. The cooperation between the mounting portion 322 and the side panel 11 can restrict the offset of the back panel assembly 3 in the vertical direction and the rotational direction. In this way, the back panel assembly 3 can be reliably mounted on the whole machine.

[0035] When the main body of the range hood (including the cabinet 1, the smoke collecting hood 2, etc. as described above) has been installed in the user's home, the back panel assembly 3 is first brought close to the wall, then installed from top to bottom, then the support groove 3241 of the rear plate 32 is snapped onto the bushing 222 of the screw bushing assembly 22, and finally two screws are used to fix the mounting portion 322 of the rear plate 32 and the side panel 11 of the cabinet 1, thus completing the installation of the back panel assembly 3.
