Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a duct structure and a heater. Background Technology

[0002] In the heating equipment sector, most heaters on the market currently suffer from limited airflow. Traditional heaters have a single-direction air outlet, often blowing air only in a specific direction, resulting in a narrow heating range. For example, in a family gathering, if a typical unidirectional heater is used, only some people will feel warm while others may remain cold, failing to meet the heating needs of multiple people simultaneously. Furthermore, in public places like restaurants, customers' legs often don't receive adequate warmth while dining.

[0003] Although some heating devices with multi-directional air supply exist in the existing technology, they generally have the following technical defects: 1. The air supply range is limited, and it is impossible to achieve true 360° all-round air supply; 2. The hot air distribution is uneven, with the area near the air outlet being too hot and the area far from the air outlet being too cold; 3. The height is fixed, and it cannot adapt to the heating needs of people of different heights.

[0004] In view of this, it is indeed necessary to improve the existing air duct structure and heaters to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a duct structure that allows for airflow from all sides.

[0006] To achieve the above objectives, this utility model provides an air duct structure, comprising:

[0007] The housing has an air inlet on one axial side and multiple air outlets on the outer peripheral wall;

[0008] The flow guiding array consists of multiple flow guiding structures located inside the shell and distributed circumferentially along the shell.

[0009] The flow guide channel is formed by the flow guide structure and the outer peripheral wall of the shell. The flow guide channel has a flow guide port, and an air inlet cavity is formed between two adjacent flow guide structures, which connects the air inlet and the flow guide port of one of the flow guide structures.

[0010] The external airflow enters the housing through the air inlet, flows into the corresponding guide groove through the air inlet cavity and guide port, and then flows out of the housing through the air outlet.

[0011] Optionally, the airflow guiding structure has a first airflow guiding surface facing the air inlet cavity and a second airflow guiding surface facing away from the air inlet cavity. After the external airflow enters the housing from the air inlet, it is guided by the first airflow guiding surface to the airflow guiding port of the adjacent airflow guiding structure and then enters the airflow guiding groove of the adjacent airflow guiding structure, and flows along the second airflow guiding surface of the adjacent airflow guiding structure to the air outlet.

[0012] Optionally, the flow guiding structure includes a bottom wall that fits into the housing and a side wall perpendicular to the bottom wall. The side wall includes a first end near the flow guiding port and a second end away from the flow guiding port. The cross-section of the bottom wall gradually decreases from the first end toward the second end.

[0013] Optionally, the first and second guiding surfaces are walls of the guiding structure arranged opposite each other, and are constructed as guiding curved surfaces.

[0014] Optionally, the outer peripheral wall of the housing is arranged in a grid pattern, and the air outlet is formed by the gaps in the grid.

[0015] Optionally, a heating device is provided at the flow outlet.

[0016] Another objective of this invention is to provide a heater that includes the above-described air duct structure.

[0017] To achieve the above objectives, this utility model provides a heater, comprising:

[0018] The above-mentioned air duct structure;

[0019] The first bracket is detachably connected to the housing of the air duct structure;

[0022] Optionally, the connector is a knob fitted on the first bracket, and the knob is configured to lock into the second bracket after the first bracket reaches a predetermined position.

[0023] Optionally, the bottom of the housing is provided with a protruding connecting post, and the top of the first bracket is provided with a corresponding connecting hole. The connecting post extends into the connecting hole and is fixedly connected to the first bracket.

[0024] The beneficial effects of this utility model are:

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0040] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0041] like Figure 1 The image shows a heater 100 provided by this utility model. The heater 100 includes an air duct structure 200, a first support 300, and a second support 400. The air duct structure 200 is responsible for guiding and heating the airflow, while the first support 300 and the second support 400 are used to support and adjust the height of the heater 100, enabling the heater 100 to achieve both 360° uniform airflow and height adjustment.

[0042] like Figures 3-4 As shown, the air duct structure 200 includes a housing 210 and a flow guide array disposed within the housing 210. The housing 210 includes an air inlet 2101 and multiple air outlets 2102.

[0043] The air inlet 2101 is located on one axial side of the housing 210 and is used to introduce external air to ensure that air can smoothly enter the interior of the housing 210 while preventing foreign objects from entering. Preferably, in this embodiment, the air inlet 2101 is located at the bottom of the housing 210.

[0044] Multiple air outlets 2102 are located on the outer peripheral wall 2103 of the housing 210. In this embodiment, the outer peripheral wall 2103 of the housing 210 is arranged in a grid shape, and the multiple air outlets 2102 are formed by the gaps in the grid. The grid-shaped outer peripheral wall 2103 not only serves to guide airflow but also prevents foreign objects from entering the heater 100, ensuring safe use. At the same time, the evenly distributed grid gaps ensure that the airflow can flow out evenly, achieving annular airflow. When the airflow flows towards the air outlet 2102, the grid will evenly disperse the airflow, so that the entire annular surface can have stable airflow.

[0045] like Figure 4As shown, the flow guiding array is composed of multiple flow guiding structures 220 distributed circumferentially along the housing 210. The flow guiding structure 220 of this invention can be three or more. In this embodiment, three flow guiding structures 220 are provided, and the three flow guiding structures 220 are centrally symmetrically distributed at 120°. Each flow guiding structure 220 adopts a logarithmic spiral design.

[0046] like Figures 4-5 As shown, multiple flow guiding structures 220 and the outer peripheral wall 2103 of the housing 210 form multiple flow guiding channels 2201. Each flow guiding channel 2201 has a flow guiding port 2210, and an air inlet cavity 2104 is formed between two adjacent flow guiding structures 220, connecting the air inlet 2101 and the flow guiding port 2210 of one of the flow guiding structures 220. The arrangement of the flow guiding channels 2201 allows the airflow to flow evenly within the housing 210, ultimately achieving an annular air outlet effect. When external airflow enters from the air inlet 2101, it first enters each air inlet cavity 2104, then flows evenly into different flow guiding channels 2201 through the flow guiding ports 2210, and finally flows out of the housing 210 from the air outlet 2102, ensuring that airflow exits from the entire annular surface.

[0047] The airflow guiding structure 220 has a first airflow guiding surface 2202 facing the air inlet cavity 2104 and a second airflow guiding surface 2203 facing away from the air inlet cavity 2104. Each first airflow guiding surface 2202 is positioned towards the airflow opening 2210 of the adjacent airflow guiding structure 220. Thus, after external airflow enters the housing 210 from the air inlet 2101, it is guided by the first airflow guiding surface 2202 to the airflow opening 2210 of the adjacent airflow guiding structure 220, then enters the airflow channel 2201 of that adjacent airflow guiding structure 220, and finally flows along the second airflow guiding surface 2203 of that adjacent airflow guiding structure 220 to the air outlet 2102. This design optimizes the airflow path and improves airflow utilization. Taking one of the airflow guiding structures 220 as an example, the airflow, guided by the first airflow guiding surface 2202, can accurately enter the adjacent airflow channel 2201, reducing airflow turbulence and energy loss.

[0048] Of course, it is understandable that after the external airflow enters the housing 210, some of the airflow flows along the first guide surface 2202 into the guide groove 2201 of the adjacent guide structure 220, and then flows out directly from the air outlet 2102 without passing through the second guide surface 2203. Therefore, the setting of the second guide surface 2203 widens the airflow path, making the annular airflow more uniform.

[0049] The airflow guiding structure 220 includes a bottom wall 2204 that fits against the housing 210 and a side wall 2205 perpendicular to the bottom wall 2204. The side wall 2205 includes a first end 2251 near the airflow inlet 2210 and a second end 2252 away from the airflow inlet 2210. The cross-section of the bottom wall 2204 gradually tapers from the first end 2251 toward the second end 2252. This shape design helps guide the airflow within the airflow channel 2201, enhancing the airflow speed and pressure. As the airflow flows within the airflow channel 2201 with its gradually tapering cross-section, the airflow speed also increases accordingly, thereby improving the airflow effect.

[0050] Furthermore, in this embodiment, the blade 2110 structure at the air inlet 2101 is configured to correspond to the first guide surface 2202, so that the airflow entering the air inlet cavity 2104 from the blade 2110 can flow directly to the first guide surface 2202 and flow from the first end 2251 to the second end 2252.

[0051] The first guide surface 2202 and the second guide surface 2203 are oppositely arranged walls of the guide structure 220, and are constructed as guide curved surfaces, that is, extending circumferentially inside the housing 210 in a logarithmic spiral manner, so that the entire side wall 2205 is arc-shaped. The arc-shaped side wall 2205 further optimizes the airflow trajectory, allowing the airflow to flow more smoothly in the guide groove 2201, reducing the friction between the airflow and the side wall 2205, and improving the uniformity of the airflow.

[0052] A heating device 230 is provided at the airflow inlet 2210. The heating device 230 heats the airflow as it passes through, turning the outflowing air into hot air to meet heating needs. The heating device 230 can use common heating elements such as electric heating wires or PTC ceramic heaters; the specific choice should be based on actual needs and cost considerations.

[0053] In this embodiment, after the external airflow enters through the air inlet 2101, it is evenly distributed to three independent air inlet chambers 2104. Guided by the first guide surface 2202, the airflow smoothly turns and enters the adjacent guide groove 2201. Within the guide groove 2201, part of the airflow spirals forward along the second guide surface 2203 and is finally evenly discharged from the air outlet 2102 on the grille.

[0054] like Figures 1-2As shown, the first bracket 300 is detachably connected to the housing 210 of the air duct structure 200. The bottom of the housing 210 has a protruding connecting post 2105, and the top of the first bracket 300 has a corresponding connecting hole 310. The connecting post 2105 extends into the connecting hole 310 and is fixedly connected to the first bracket 300. This design facilitates assembly and disassembly in different usage scenarios. In this embodiment, the heater 100 is a floor-standing design. In other embodiments, for example, when wall-mounted use is required, the air duct structure 200 can be easily detached from the first bracket 300 for installation via the connecting post 2105. In another embodiment, the heater 100 can also be suspended from a supporting surface via the connecting post 2105.

[0055] The second bracket 400 is connected to the first bracket 300 and can be raised or lowered relative to the first bracket 300. This lifting structure allows the height of the air outlet 2102 of the heater 100 to be adjusted according to the height and heating needs of different individuals. For example, for taller people, the first bracket 300 can be raised to make the height of the air outlet 2102 more suitable for their heating needs. For children or shorter people, the first bracket 300 can be lowered for better heating.

[0056] like Figure 6 As shown, the heater 100 also includes a connector 500. The connector 500 is disposed on the first bracket 300 and / or the second bracket 400, and the first bracket 300 and the second bracket 400 are locked and fixed by the connector 500. The connector 500 ensures that the first bracket 300 can be stably maintained in the position after the height is adjusted, without shaking or slipping.

[0057] In this embodiment, the connector 500 is a knob sleeved on the first bracket 300. The knob is configured to lock into the second bracket 400 after the first bracket 300 reaches a predetermined position. This knob-type connector 500 is simple and convenient to operate, and users can easily adjust and fix the height of the first bracket 300 by rotating the knob.

[0058] When installing the heater 100, first insert the connecting post 2105 at the bottom of the air duct structure 200 into the connecting hole 310 at the top of the first bracket 300 and secure it. Then, adjust the height of the first bracket 300 by rotating the knob according to actual usage needs, so that the air outlet 2102 of the heater 100 is in a suitable position. Finally, tighten the knob. If it is necessary to change the installation method of the heater 100, such as changing from a floor-standing type to a wall-mounted type, the first bracket 300 can be separated from the air duct structure 200, and wall-mounted installation can be performed using the connecting post 2105.

[0059] In summary, the air duct structure 200 of this utility model, by setting multiple airflow guiding structures 220 inside the housing 210, can guide the airflow entering the housing 210, enabling the heater 100 to achieve 360° circumferential airflow. Furthermore, through the lifting and lowering coordination of the first bracket 300 and the second bracket 400, the heater 100 can adapt to heating needs at different heights. Simultaneously, the first bracket 300 is detachably connected to the housing 210 of the air duct structure 200, allowing the heater 100 to meet various needs such as wall-mounted, suspended, and floor-standing installations.

[0060] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
