Description

Technical Field

[0001] This utility model relates to the field of heaters, and specifically to a structure for a long-outlet main unit. Background Technology

[0002] The existing heater main unit structure has many shortcomings in practical applications: First, the direct-light lamp housing design limits the space between the panel and the main unit, and the traditional main unit's single air inlet design results in insufficient air intake, which in turn affects the air output of the warm air outlet and leads to low heating efficiency; Second, the thermostat in the heating element is installed in an unreasonable position, resulting in delayed or inaccurate temperature detection, posing a safety hazard, and the heating block pins lack effective isolation, requiring additional silicone sleeves to meet safety requirements, increasing costs.

[0003] Therefore, in order to overcome the shortcomings of the existing technology, it is necessary to design a simple long-outlet main unit structure. Utility Model Content

[0004] This utility model provides a long-outlet air-generating host structure to solve the problems of the prior art.

[0005] The objective of this utility model can be achieved through the following technical solution: A long-outlet main unit structure includes: a main unit housing, a main unit cover plate, a fan assembly, and a heating assembly. The main unit housing has an internal air duct, the fan assembly is installed inside the air duct, the heating assembly is installed on one side of the air duct, and an air exchange port is provided on the long side of the main unit housing, located on the other side of the air duct. The main unit cover plate is fixed to the end face of the main unit housing. The main unit cover plate has mounting holes facing the heating assembly. Air inlet slots are provided in the middle of the long side and the middle of the short side of the main unit cover plate. A mesh cover is provided on the main unit cover plate facing the fan assembly. The heating assembly includes a heating frame, a PCT heating block, and a temperature controller. The PCT heating block is installed inside the heating frame, and the temperature controller is installed at the lower end of the PCT heating block via a bracket. The heating frame is provided with spacers at intervals, which separate the pins of the PCT heating block.

[0006] As a further improvement, the air duct is provided with an arc-shaped guide surface at the transition point to the heating element.

[0007] In a further improvement, the end face of the heating frame is provided with grid strips at intervals, and an air outlet channel is provided between the grid strips, with the grid strips on both sides inclined inward.

[0008] In a further improvement, the right side of the main unit cover is provided with a cavity for accommodating the wiring module, and a wire cover is fastened to the outside of the cavity, with wire outlet holes at both ends of the wire cover.

[0009] As a further improvement, the mesh cover is provided with baffles spaced in a ring.

[0010] Compared with the prior art, the beneficial effects of the extended air outlet main unit structure of this utility model are as follows:

[0011] The multi-directional design of the air inlet slot breaks through the space limitations of the direct-light lamp housing, significantly increasing the air intake volume and solving the problem of insufficient air output from traditional panel warm air vents, thus improving heating efficiency. The thermostat is close to the lower end of the PCT heating block, making temperature detection more direct and accurate, with a shorter response time. It can quickly trigger protection when the product is not operating normally, improving safety. The partition of the heating frame replaces the traditional silicone sleeve, which not only meets the creepage distance requirements of the live and neutral wires in safety regulations, but also reduces the material cost of the silicone sleeve and simplifies the assembly process.

[0018] The following is a description of the embodiments and appendices. Figures 1-4The technical solution of this utility model will be further described below.

[0019] Example 1

[0020] A long-exhaust main unit structure includes: a main unit housing 1, a main unit cover 2, a fan assembly 3, and a heating element 4. The main unit housing 1 has an internal air duct 12, the fan assembly 3 is installed within the air duct 12, and the heating element 4 is installed on one side of the air duct 12. An air exchange port 11 is provided on the long side of the main unit housing 1, located on the other side of the air duct 12. The main unit cover 2 is fixed to the end face of the main unit housing 1, and has mounting holes 5 facing the heating element 4. Air inlet slots 21 are provided at the middle of the long side and the middle of the short side of the cover plate 2. The main cover plate 2 is provided with a mesh cover 22 facing the fan wheel assembly 3. The heating assembly 4 includes a heating frame 41, a PCT heating block 42 and a temperature controller 43. The PCT heating block 42 is installed inside the heating frame 41. The temperature controller 43 is installed at the lower end of the PCT heating block 42 through a bracket 44. The heating frame 41 is provided with partitions 411 at intervals. The partitions 411 separate the pins 421 of the PCT heating block 42.

[0021] like Figures 1-4 As shown, the working principle of this utility model is as follows:

[0022] Air inlet slots 21 are provided at the middle of both the long and short sides of the main unit cover 2. By utilizing the limited space between the panel and the main unit, air inlet paths are opened from multiple directions (long and short sides) to increase the air inlet area. When the impeller assembly 3 is working, it draws in air from multiple directions through the air inlet slots 21 and delivers it to the heating element 4 through the air duct 12.

[0023] The heating element 4 uses a PCT heating block 42 as a heat source, which is installed inside the heating frame 41. Heat is transferred through airflow to achieve heating. The thermostat 43 is directly installed on the lower end of the PCT heating block 42 through the bracket 44, in close contact with the heat source. The partition 411 of the heating frame 41 physically separates the pins 421 (live and neutral wire pins) of the PCT heating block 42 to avoid direct contact between the pins.

[0024] Outside air enters through the air inlet slot 21, is driven by the impeller assembly 3, and is guided through the air duct 12 to the heating element 4. After being heated by the PCT heating block 42, it is sent out through the mounting hole 5. At the same time, the air exchange port 11 can realize the exchange of air between the inside of the host and the outside.

[0025] The multi-directional design of the air inlet slot 21 breaks through the space limitations of the direct-light lamp housing, significantly increasing the air intake volume and solving the problem of insufficient air output from traditional panel warm air vents, thus improving heating efficiency; the thermostat 43 is close to the lower end of the PCT heating block 42, making temperature detection more direct and accurate, with a shorter response time, and can quickly trigger protection when the product is not working properly, improving safety; the partition 411 of the heating bracket 41 replaces the traditional silicone sleeve, which not only meets the creepage distance requirements of the live and neutral wires in safety regulations, but also reduces the material cost of the silicone sleeve and simplifies the assembly process.

[0026] As a further preferred embodiment, the air duct 12 is provided with an arc-shaped guide surface 121 on the side where it transitions to the heating element 4. Traditional air ducts often have right-angle or acute-angle structures when transitioning to the heating element, which easily form turbulence and eddies when airflow passes through, resulting in increased wind resistance and energy loss. The arc-shaped guide surface 121 guides the airflow along an arc-shaped path through a smooth curved transition, reducing abrupt changes in airflow direction.

[0027] As a further preferred embodiment, the end face of the heating frame 41 is provided with spaced grid strips 412, and an air outlet channel 413 is provided between the grid strips 412. The grid strips 412 on both sides are inclined inward. In traditional heating frames, the grid strips are mostly arranged vertically or parallel, and the airflow after heating tends to diffuse to both sides when passing through the air outlet channel, resulting in rapid attenuation of wind speed. The grid strips 412 on both sides are inclined inward to form a "contractive" air outlet channel 413, which has a converging and guiding effect on the airflow, reduces airflow diffusion, and increases the outlet wind speed of the heated airflow.

[0028] As a further preferred embodiment, the right side of the main unit cover 2 is provided with a cavity 23 for accommodating the wiring module. A wire cover 24 is fastened to the outside of the cavity 23, and the wire cover 24 has wire outlet holes 25 at both ends. Traditional main unit wiring modules do not have dedicated space for accommodating the module, resulting in messy wiring; the wire outlet holes are mostly unidirectional, requiring bending of the wires in complex scenarios; and the wire cover is mostly fixed with screws, making installation cumbersome. The cavity 23 is specifically designed to accommodate the wiring module, achieving neat wiring; the wire cover 24 is connected to the cavity 23 by a fastening method, eliminating the need for screws; and the wire outlet holes 25 at both ends of the wire cover 24 provide two different directions for wire lead-out paths.

[0029] As a further preferred embodiment, the mesh cover 22 is provided with annularly spaced baffles 221. Traditional wind turbine assembly mesh covers are mostly open meshes with no obstruction, allowing foreign objects such as power cords and plugs to easily fall into the wind turbine assembly 3 through the mesh cover during installation. The baffles 221 of the mesh cover 22 form an annularly distributed physical barrier, preventing foreign objects from passing through the mesh cover and contacting the wind turbine.

[0030] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
