Description

Technical Field

[0001] This utility model relates to the field of range hoods, and specifically to a range hood volute assembly. Background Technology

[0002] A range hood, also known as a cooking hood, is a kitchen appliance used to purify the kitchen environment. Installed above the stove, it quickly removes waste from combustion and harmful fumes produced during cooking, expelling them outdoors. It also condenses and collects these fumes, reducing pollution, purifying the air, and providing safety features such as protection against toxic substances and explosions.

[0003] Range hoods generally include a smoke extraction chamber and a blower box. The blower box contains a volute assembly, which mainly includes a volute, a motor, and an impeller. As shown in CN104929983A, the volute includes a volute plate (enclosure) and two side guards. The opening of one side guard is smaller than that of the other side guard, and it is used to house the frame and the motor.

[0004] However, since the range hood needs to be disassembled for maintenance after working for a period of time, it is not very convenient to disassemble and maintain it because it can only be disassembled from the other side of the frame (that is, the air guide ring is removed from the side of the guard plate with a larger opening, and then the motor and impeller are disassembled). This is due to the limitations of the range hood's structure itself.

[0005] Therefore, the inventors conducted further research and developed a range hood volute assembly, which led to this invention. Utility Model Content

[0006] The purpose of this utility model is to provide a range hood volute assembly that improves the convenience of disassembling and maintaining the volute assembly.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A range hood volute assembly, comprising

[0009] The enclosure has a first guard plate and a second guard plate on both sides.

[0010] The first guard plate is equipped with a chassis, the chassis is equipped with a frame, and the frame is equipped with a motor that can drive the impeller to rotate.

[0011] The second guard plate is equipped with an air guide ring;

[0012] After the chassis is removed from the first guard plate, the impeller and motor are taken out from one side of the first guard plate along with the chassis.

[0013] In the existing structure, the motor needs to be disassembled from the side of the air guide ring, and the impeller cannot be removed from the side of the protective plate where the frame is located. The above improvements have increased the disassembly efficiency of the impeller and the motor.

[0014] Furthermore, the opening dimensions of the first and second protective plates are consistent, with a dimensional error range not exceeding ±10%.

[0015] The opening here refers to the circular through hole that occupies most of the area on the protective plate. The opening size on both sides of the protective plate is the same, but they do not have to be exactly the same.

[0016] Furthermore, both the air guide ring and the chassis are bolted to their respective protective plates.

[0017] Furthermore, the frame includes a support frame and an inner ring. Several supports are provided on the inner ring. The support frame is connected to the chassis. The inner ring is used to install the motor.

[0018] Furthermore, the bracket and chassis are an integrated structure, with the bracket recessed inward relative to the chassis.

[0019] Furthermore, four supports are installed between the inner ring and the chassis, and the supports are evenly distributed.

[0020] By adopting the above solution, this utility model has the following advantages compared with the prior art:

[0021] The entire impeller, motor, and other components can be disassembled from the volute assembly for maintenance from one side of the motor chassis; this reduces the limitations of the overall structural design of the range hood, allowing the volute to be matched with more types of components, improving maintenance efficiency, and thus enhancing market competitiveness.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-3As shown, a range hood volute assembly includes a surrounding plate 11, a first protective plate 12, and a second protective plate 13 constituting the main structure of the volute 1. The first protective plate 12 and the second protective plate 13 are disposed on both sides of the volute 1, and both protective plates have through holes in the middle. A frame that is recessed inward is provided on one side of the first protective plate 12. The frame includes an inner ring 32 for mounting a motor 4 and a bracket 31 connecting the inner ring 32 and the first protective plate 12. In this embodiment, the bracket 31 is evenly distributed in a cross shape on the side of the inner ring 32, and the motor 4 is installed in the inner ring 32.

[0030] like Figure 2 As shown, the chassis 2 and the first guard plate 12 are connected by a number of evenly distributed bolt holes, and the through hole in the middle of the first guard plate 12 is larger than the diameter of the impeller 6. When the chassis 2 is disassembled, the entire chassis 2, along with the impeller 6 and the motor 4, can be removed from the side of the first guard plate 12.

[0031] like Figure 3 As shown, a guide ring 5 is provided on one side of the second guard plate 13, and the guide ring 5 has a mesh protective structure in the middle. In the prior art, due to structural limitations, the impeller 6 enters from the guide ring 5, is aligned with the motor shaft 4, and then installed; however, in the concept of this utility model, it can be installed from... Figure 2 Remove the impeller 6, motor 4, and chassis 2 together from the viewing angle.

[0032] The above are merely specific embodiments of this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this utility model are for reference only and are not absolute limitations. Any non-substantial modifications made to this utility model shall be considered as infringing upon the protection scope of this utility model.
