Description

TECHNICAL FIELD

[0001] The utility model relates to domestic appliance technical field especially relates to a ring shape air outlet structure. BACKGROUND

[0002] The heater is a kind of heater that utilizes electric heating heating body to generate heat, then utilizes fan to make air flow, blows out the heat generated by heating body, and heats indoor environment.The commonly used heater is mainly composed of shell, motor and heating body, the motor and heating body are arranged in the shell, the shell is provided with air inlet and air outlet, the air outside is sucked into the shell from the air inlet by the blade driven by the motor, then is blown out from the air outlet, and the heating body is arranged in the air flow channel connected with the air outlet, the existing heating body is changed from original whole section to multi-section setting for reducing cost and facilitating maintenance, the annular body is surrounded by multi-section heating body, and sectional control is adopted, that is, a part of heating body works, and a part of heating body does not work, to adjust outlet temperature, for example, half of heating body works, and half of heating body does not work, and the working heating body and the non-working heating body are alternately arranged, but there is gap between adjacent heating bodies, if the gap distance is too large, when a part of heating body does not work, the length proportion of non-working in annular body is too high, and the problem of uneven outlet temperature is caused, and if the gap distance is too small, adjacent heating bodies will generate creeping phenomenon, leading to insulation damage, greatly influence user experience. CONTENT OF UTILITY MODEL

[0003] To solve the above problems, the utility model provides a ring shape air outlet structure, including air guide frame, the middle part of air guide frame is provided with air inlet, the edge of air guide frame is provided with annular air outlet, and the annular air outlet is evenly arranged with mounting frame, and the mounting frame is provided with heating block, and the spacing between adjacent heating blocks is at least 56mm.

[0004] Further, the outer wall of the air guide frame is provided with a fixing frame for connecting with the main machine of the electric appliance.

[0005] Further, the mounting frame includes an inner long frame and an outer short frame, and the heating blocks are arranged in the mounting frame according to the shape of the mounting frame.

[0006] Further, the outer short frame is provided with heating block buckles at both ends, and the heating block buckles are fixed with the top surface of the heating block.

[0007] Further, the spacing between the short edges of adjacent heating blocks is at least 56mm.

[0008] The utility model has the advantages of:

[0009] 1. The spacing between heating blocks should be at least 56mm to avoid the problem of creepage between adjacent heating elements due to insufficient spacing, which could lead to insulation failure, and also to avoid the problem of reduced heating effect due to excessive spacing.

[0010] 2. A heating block clip is provided inside the short outer frame of the mounting frame to facilitate the installation and removal of the heating block.

[0011] 3. The heating element is longer inside and shorter outside, allowing more airflow to be forced from the outside to the inside, solving the problem of uneven heat dissipation between the inside and outside. This results in better workmanship and a longer lifespan for the entire heating element. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be further described in detail below with reference to embodiments. Specific details will be involved in the following description to ensure a thorough understanding of the present invention. However, the present invention can still be realized without these specific details, meaning that those skilled in the art can more effectively explain the nature of their work to other skilled in the art using these descriptions and statements herein. Furthermore, it should be understood that the specific embodiments described herein are merely illustrative of the application and are not intended to limit the actual scope of protection. All raw materials used in the following embodiments are commercially available products.

[0016] Example 1

[0017] like Figs. 1-2 As shown, an annular air outlet structure includes an air guide frame, an air inlet 1 in the middle of the air guide frame, an annular air outlet at the edge of the air guide frame, mounting frames 2 evenly arranged inside the annular air outlet, heating blocks 5 arranged inside the mounting frames 2, and the distance between adjacent heating blocks 5 is at least 56mm.

[0018] Furthermore, the outer wall of the air guide frame is provided with a fixing bracket 6 for connecting to the electrical main unit.

[0019] Furthermore, the mounting frame 2 includes an inner long frame 4 and an outer short frame 3, and the heating block 5 is selected and set according to the shape of the mounting frame.

[0020] Further, the heating block buckle 7 is arranged at the left and right ends of the outer short frame 3, and the heating block buckle 7 is fixed to the top surface of the heating block 5.

[0021] Further, the interval D between the short sides of the adjacent heating blocks 5 is at least 56 mm.

[0022] The interval between the heating blocks 5 is at least 56 mm, which can avoid the problem of insulation failure caused by the creeping phenomenon between the adjacent heating bodies due to the small interval, and can also avoid the problem of reduced heating effect caused by the large interval; the heating block buckle is arranged in the outer short frame of the mounting frame, which facilitates the installation and disassembly of the heating block. Since the airflow driven by the rotation of the wind wheel is rotated and blown out, the airflow is more likely to flow out along the outer wall due to inertia, resulting in better heat dissipation on the outer side than on the inner side of the entire heating block. The heating block structure adopted in the utility model is long inside and short outside, which can make more airflow flow into the inner side from the outer side, balance the uneven heat dissipation problem of the inner and outer sides, make the entire heating block work more efficiently, and have a longer service life.

[0023] The above describes the technical solutions of the embodiments of the utility model in detail, and the principles and implementation modes of the embodiments of the utility model are described by applying specific examples. The above description of the embodiments is only applicable to help understand the principles of the embodiments of the utility model; meanwhile, for the general technical personnel in the field, the embodiments of the utility model, the specific implementation modes and the application range will be changed, and the above description should not be understood as the limitation of the utility model.
