Description

Technical Field

[0001] The utility model relates to the technical field of fresh air equipment, in particular to an integrated fresh air unit with an electric control assembly. Background Art

[0002] With the continuous improvement of modern people's requirements for indoor environmental quality, technologies in the heating, ventilation and air conditioning (HVAC) field are also developing rapidly. To meet the demands for refined management of indoor temperature control and air quality (such as oxygen content and cleanliness) at the same time, the "integrated fresh air air-conditioning unit" technology that integrates fresh air ventilation and air-conditioning cooling / heating functions has emerged. Compared with the traditional split fresh air system and air-conditioning system, this type of integrated unit usually has the characteristics of saving installation space, simplifying pipelines and realizing linkage control, so it has gradually become one of the favored solutions for environmental control in buildings and residences at present.

[0003] In the conventional technology, in order to improve the energy saving performance of the integrated unit, the industry has proposed a variety of complex energy recovery solutions. For example, Chinese patent application CN114935187A discloses a winter-summer dual-working-condition energy-saving sprayable fresh air air-conditioning integrated unit. In this solution, by constructing a complex dual refrigeration system and multiple sets of fins, the discharged indoor air is used to pre-cool or pre-heat specific fins in the unit; even the condensed water generated on the fresh air side is further used, which is sprayed onto the fin system on the return air side through a water pump, so as to reduce the working condition point of the compressor and achieve the purpose of energy saving. However, although this design carries out in-depth optimization on the thermal performance, it also leads to a highly complicated internal structure of the unit, in which the vibration-generating compressor, fan, filter screen, and the spray and dual-water-pump drainage systems involving liquid water are mixed and arranged in the same unit. While pursuing complex heat exchange and water circuit utilization, this solution does not clearly plan an independent and protected installation space for the core electric control assembly.

[0004] However, the current integrated fresh air air-conditioning units including the above-mentioned patent generally have a problem in structural layout: they often arrange the precision electric control assemblies and functional components that generate vibration (such as compressors), high heat (such as condensers) or moisture (such as evaporators, condensate trays, spray systems) in the same unit chamber, or in adjacent areas without effective physical isolation. This makes the electric control assemblies exposed to adverse environments of humidity, high temperature, vibration and dust for a long time, which easily leads to corrosion of circuit boards, overheating and aging of electronic components, poor contact or even short circuit of wiring terminals, or connection failure caused by vibration. This not only seriously affects the operation stability and reliability of the whole unit and shortens the service life of the product, but also brings great inconvenience to the later inspection and maintenance because the electric control components are scattered in layout or hidden deep in the complex structure. Contents of the Utility Model

[0005] Therefore, it is necessary to provide a fresh air unit with electronic control components to address the above problems.

[0006] This application provides a fresh air unit with electronic control components. The fresh air unit includes a frame, and a fresh air module and an outdoor unit module disposed on the frame. The frame includes a partition and a panel. The partition and the panel form a first receiving cavity and a second receiving cavity. The first receiving cavity and the second receiving cavity are arranged in a vertical direction. The fresh air module and the outdoor unit module are respectively disposed in the first receiving cavity and the second receiving cavity. The fresh air module includes a top cover and a side panel. A third receiving cavity is formed between the side panel and the panel of the frame. The third receiving cavity is connected to one side of the first receiving cavity. The third receiving cavity is used to house the electrical control components. The electrical control components are electrically connected to the fresh air module and the outdoor unit module, respectively.

[0007] Optionally, the electrical control assembly includes a terminal block and a control box, with the terminal block disposed within the third receiving cavity.

[0008] Optionally, the control box is disposed in the third receiving cavity and is arranged vertically with the compressor. An inspection port is provided on the front panel, and the inspection port is provided corresponding to the control box and the compressor. An inspection cover is provided on the inspection port.

[0009] Optionally, the control box is located at the junction of the third and second accommodating cavities and is arranged vertically with the compressor. An inspection port is provided on the front panel, which is corresponding to the control box and the compressor. The inspection port is provided with an inspection cover.

[0010] Optionally, the wiring terminals are connected to the panel via a mounting plate.

[0011] Optionally, the mounting plate is angled to the panel so that the wiring terminals face the fresh air module.

[0012] Optionally, the electrical control box is provided with a main control board. The electrical control box includes a cover and a panel, and the cover and panel together form a space suitable for setting the main control board.

[0013] Optionally, the electrical control box has a wire hole on the side facing the second receiving cavity.

[0014] Optionally, a sealing element is provided at the connection between the box lid and the box panel.

[0015] This application also provides a fresh air unit with electronic control components, including a frame, and a fresh air module and an outdoor unit module disposed on the frame. The frame includes a partition and a panel, the partition and the panel forming a first receiving cavity. The fresh air module includes a top cover and a side panel, and a third receiving cavity is formed between the side panel and the panel of the frame. The third receiving cavity is connected to one side of the first receiving cavity. The third receiving cavity is used to house the electronic control components, so that the electronic control components are physically isolated from the fresh air module.

[0016] Optionally, the partition and the panel further form a second receiving cavity, the first receiving cavity and the second receiving cavity are arranged in a vertical direction, and the outdoor unit module is disposed in the second receiving cavity, so that the electronic control component and the outdoor unit module are physically isolated.

[0017] Compared with the prior art, the technical solution provided in this application has the following advantages: The aforementioned integrated fresh air unit with electronic control components constructs two vertically aligned accommodating cavities—a first and a second—by setting up a frame, partitions, and a panel, respectively accommodating the fresh air module and the outdoor unit module. This structural design firstly achieves the integration of fresh air function and outdoor unit function (such as cooling and heating) within a unified frame. Compared to the traditional separate installation of fresh air and air conditioning outdoor units, its structure is more compact, significantly saving installation space and floor area, and achieving a high degree of integration. Instead of placing the electronic control components directly within any of the aforementioned functional cavities, it utilizes the side panel of the fresh air module and the panel of the frame to form an additional independent third accommodating cavity, which is dedicated to housing the electronic control components.

[0018] The independent cavity design firstly achieves functional isolation and improved operational stability. The fresh air module (first cavity) involves air circulation, which may be accompanied by moisture and dust; while the outdoor unit module (second cavity) generates heat, vibration, and potential condensation during operation. As the core control unit of the equipment, the electrical control components have high environmental requirements. Placing them in a separate third cavity effectively isolates them from the two functional modules, thus effectively preventing the electrical control components from being adversely affected by moisture, dust, high temperatures, and vibration. This significantly improves the operational stability and reliability of the electrical control system and extends its service life. At the same time, this layout also optimizes the structure and ensures ease of maintenance. The third cavity connects to one side of the first cavity. This layout physically places the electrical control components adjacent to the two major functional modules, facilitating electrical connections (for centralized control) between the electrical control components and the fresh air module and outdoor unit module respectively, while also shortening wiring paths. Furthermore, since the electrical control components are located in a separate cavity formed by the panel (outside the frame), when the electrical control components need to be inspected or replaced, maintenance personnel may only need to open the corresponding panel to operate, without having to disassemble the complex fresh air module or outdoor unit module, thus significantly improving the convenience of installation and subsequent maintenance.

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] See Figure 1 and Figure 2 This utility model provides a fresh air unit with an electronic control component 400. The fresh air unit includes a frame 100, and a fresh air module 200 and an outdoor unit module 300 disposed on the frame 100. The frame 100 includes a partition 110 and a panel 120. The partition 110 and the panel 120 form a first receiving cavity 130 and a second receiving cavity 140. The first receiving cavity 130 and the second receiving cavity 140 are arranged vertically. The fresh air module 200 and the outdoor unit module 300 are respectively disposed in the first receiving cavity 130 and the second receiving cavity 140. The fresh air module 200 includes a top cover 210 and a side plate 220. A third receiving cavity 150 is formed between the side plate 220 and the panel 120 of the frame 100. The third receiving cavity 150 is connected to one side of the first receiving cavity 130 and is used to house the electronic control component 400. The electronic control component 400 is electrically connected to the fresh air module 200 and the outdoor unit module 300, respectively.

[0023] This embodiment constructs two vertically arranged first and second receiving cavities 140 by setting up a frame 100, a partition 110, and a panel 120, which are used to accommodate the fresh air module 200 and the outdoor unit module 300, respectively. This structural design firstly achieves the effect of integrating the fresh air function and the outdoor unit function (such as cooling and heating) into a unified frame 100. Compared with the traditional separate installation of fresh air and air conditioning outdoor units, its structure is more compact, significantly saving installation space and floor area, and achieving a high degree of integration. It does not place the electronic control component 400 directly in any of the above-mentioned functional cavities, but uses the side plate 220 of the fresh air module 200 and the panel 120 of the frame 100 to form an additional independent third receiving cavity 150, which is dedicated to accommodating the electronic control component 400.

[0024] The independent cavity design firstly achieves functional isolation and improved operational stability. The fresh air module 200 (first receiving cavity 130) involves air circulation, which may be accompanied by moisture and dust; while the outdoor unit module 300 (second receiving cavity 140) generates heat, vibration, and potential condensation during operation. As the core control unit of the equipment, the electrical control component 400 has high environmental requirements. Placing it in an independent third receiving cavity 150 effectively isolates it from the two functional modules, thus effectively avoiding the adverse effects of moisture, dust, high temperature, and vibration on the electrical control component 400. This significantly improves the operational stability and reliability of the electrical control system and extends its service life. At the same time, this layout also optimizes the structure and ensures ease of maintenance. The third receiving cavity 150 connects to one side of the first cavity. This layout physically places the electrical control component 400 adjacent to the two major functional modules, facilitating electrical connections (for centralized control) between the electrical control component 400 and the fresh air module 200 and the outdoor unit module 300 respectively, while also shortening the wiring path. Furthermore, since the electrical control component 400 is located in a separate cavity formed by the panel 120 (outside the frame 100), when the electrical control component 400 needs to be inspected or replaced, the maintenance personnel may only need to open the corresponding panel 120 to operate it, without having to disassemble the complex fresh air module 200 or outdoor unit module 300, thus significantly improving the convenience of installation and subsequent maintenance.

[0025] See Figure 3 In one embodiment, the electronic control assembly 400 includes a terminal block 410 and a control box 420, with the terminal block 410 disposed within a third receiving cavity 150.

[0026] This embodiment further clarifies the specific composition of the electrical control component 400, which includes a terminal block 410 and a control box 420, and specifically points out that the terminal block 410 is located within the third receiving cavity 150. This technical feature firstly utilizes the independence and isolation characteristics of the third receiving cavity 150. The terminal block 410, as the electrical hub connecting the power supply to the whole unit and the fresh air module 200 and the outdoor unit module 300, is a critical node for electrical safety. Placing it within the previously discussed, independent and protected third receiving cavity 150 (logically, the control box 420 is also located in this cavity) ensures that these critical electrical connection points are kept away from moisture and dust that may be introduced from the first receiving cavity 130 (fresh air), as well as heat and vibration generated by the second receiving cavity 140 (outdoor unit). This layout effectively avoids the risk of corrosion, poor contact, or short circuit of the terminal block 410 due to harsh environmental factors, thereby significantly improving the electrical safety and long-term operational reliability of the whole unit. Furthermore, centralizing the main wiring interface, terminal block 410, in the third housing cavity 150 allows all electrical connections (including external power supplies and internal modules) to be gathered in an easily accessible and manageable area. This not only makes initial installation wiring more convenient and standardized, but also greatly facilitates subsequent maintenance and troubleshooting, further enhancing the technical effectiveness of this independent cavity in improving maintainability.

[0027] In one embodiment, the control box 420 is disposed in the third receiving cavity 150 and is arranged vertically with the compressor. An inspection port is provided on the front panel 120, which is corresponding to the control box 420 and the compressor. An inspection cover plate 121 is provided on the inspection port.

[0028] In this embodiment, the electronic control component 400 is placed in an independent third receiving cavity 150, while the control box 420 and the compressor (located in the second receiving cavity 140 of the outdoor unit module 300) are arranged vertically. This layout (combined with the vertical stacking of the first and second receiving cavities 140 mentioned above) achieves a reasonable partitioning of key components: the precision electronic component, the control box 420, is placed in the upper third receiving cavity 150, while the compressor, the main source of vibration and weight, is placed in the lower second receiving cavity 140.

[0029] The most significant highlight of this embodiment lies in its extreme pursuit of maintenance convenience. By creating an access port on the front panel 120, positioning it to correspond to both the control box 420 above and the compressor below, and then sealing it with an access cover 121, this design achieves an integrated maintenance access. This means that maintenance personnel do not need to open multiple panels 120 separately or disassemble complex machine structures during maintenance; they only need to open this single access cover 121 to simultaneously obtain operating space for the two most frequently inspected and adjusted critical components: the electrical control core (control box 420) and the refrigeration / heating core (compressor). This design, which combines the access points for the two core components into one, greatly simplifies the maintenance process, significantly shortens the time for troubleshooting and maintenance, and thus greatly improves the product's maintainability and user-friendliness.

[0030] See Figure 4 In one embodiment, the control box 420 is located at the junction of the third receiving cavity 150 and the second receiving cavity 140, and is arranged vertically with the compressor. The front panel 120 has an inspection port, which is corresponding to the control box 420 and the compressor. The inspection port is provided with an inspection cover plate 121.

[0031] In this embodiment, the control box 420 is located at the junction of the third receiving cavity 150 and the second receiving cavity 140, maintaining a vertical orientation with the compressor and sharing the same access port. This junction layout, situated at the bottom of the upper electronic cavity (third receiving cavity 150) and adjacent to the top of the lower outdoor unit cavity (second receiving cavity 140), optimizes the electrical connection. The control box 420 is functionally closely related to the compressor; its placement on the physical boundary with the compressor (located in the second cavity) ensures they are vertically adjacent. This layout shortens the electrical wiring distance between the control box 420 and the compressor, requiring only the wiring to pass through the partition 110 between them. This not only saves on wiring costs and reduces wiring complexity but, more importantly, reduces signal interference or power loss that may result from long-distance wiring, further improving the reliability of the electronic control system.

[0032] Secondly, this layout is key to achieving an integrated maintenance access panel. While the previous embodiment proposed a shared maintenance access panel, if the control box 420 was located in the upper part of the third chamber and the compressor in the second chamber, the significant vertical distance between them necessitated a very long and narrow access panel to accommodate both, making operation inconvenient. This embodiment, however, moves the control box 420 down to the junction, allowing it and the compressor to be spatially clustered in the same area of ​​the panel 120. This allows for a more compact and efficient design of the maintenance access panel 120. Maintenance personnel can open the same access cover 121 to simultaneously access both the electrical control core (control box 420) and the mechanical power core (compressor) within a very close range, greatly optimizing the maintenance experience and making this shared maintenance channel design more rational and efficient, resulting in a significant leap in maintenance convenience.

[0033] See Figure 5 In one embodiment, terminal 410 is connected to panel 120 via mounting plate 430.

[0034] In one embodiment, the mounting plate 430 is angled to the panel 120 so that the wiring terminal 410 faces the fresh air module 200.

[0035] In the two embodiments described above, regarding the layout of the critical electrical interface 410, this invention securely connects it to the panel 120 of the frame 100 via a mounting plate 430. This design not only provides a solid mounting foundation for the terminal block 410, preventing loosening due to vibration, but more importantly, it places this frequently operated component, the terminal block 410, on the most easily accessible outer panel 120, greatly enhancing the maintenance convenience of the aforementioned solution. Furthermore, by setting the mounting plate 430 at an angle to the panel 120, the terminal block 410 faces the fresh air module 200 (i.e., towards the interior of the unit), demonstrating ingenious ergonomic considerations. When maintenance personnel open the panel 120, the interface of the terminal block 410 (such as a screw) will be presented at an angle conducive to tool operation, rather than perpendicular or parallel to the panel 120, significantly improving the ease of operation during wiring and maintenance. Simultaneously, this inward-facing layout also facilitates guiding the wiring harness towards the fresh air module 200 within the third receiving cavity 150, resulting in neater wiring.

[0036] See Figure 6 In one embodiment, the electrical control box is provided with a main control board 440. The electrical control box includes a cover 421 and a panel 422. The cover 421 and the panel 422 together form a space suitable for setting the main control board 440.

[0037] In one embodiment, the electrical control box has a wire hole 423 on the side facing the second receiving cavity 140.

[0038] In one embodiment, a seal is provided at the connection between the lid 421 and the panel 422.

[0039] In the above embodiments, the protection of the core component of the electronic control assembly 400—the main control board 440—is achieved through a box-within-a-box dual protection system, consisting of a control box (including a cover 421 and a panel 422). The main control board 440 is first housed within the control box, which is then placed within the third receiving cavity 150. This design provides better protection for the delicate main control board 440. Furthermore, by adding a seal at the connection between the cover 421 and the panel 422, the control box is upgraded to a high-protection-level sealed unit. Building upon the macroscopic physical isolation already provided by the third receiving cavity 150, it further provides micro-environmental isolation against dust and moisture intrusion, ensuring that the main control board 440 remains dry and clean under various operating conditions. This significantly improves the extreme reliability and service life of the electronic control system.

[0040] Furthermore, this solution achieves a high degree of sealing protection while also addressing wiring requirements. By creating a cable pass-through hole 423 on the side of the electrical control box facing the second receiving cavity 140, this design perfectly complements the optimized layout of the control box 420 and the compressor (located in the second receiving cavity 140) described above (such as vertical placement or placement at the junction). It provides the shortest and most direct path for control cables (such as compressor control lines), allowing them to be safely led out from the sealed electrical control box and immediately enter the second receiving cavity 140. This design minimizes the exposed length and complexity of the wiring harness within the machine body, reduces the risk of interference, and simplifies the assembly process.

[0041] See Figure 1 and Figure 2 An embodiment of this utility model also provides a fresh air unit with an electronic control component 400, including a frame 100, and a fresh air module 200 and an outdoor unit module 300 disposed on the frame 100. The frame 100 includes a partition 110 and a panel 120, the partition 110 and the panel 120 forming a first receiving cavity 130. The fresh air module 200 includes a top cover 210 and a side panel 220, a third receiving cavity 150 formed between the side panel 220 and the panel 120 of the frame 100. The third receiving cavity 150 is connected to one side of the first receiving cavity 130. The third receiving cavity 150 is used to house the electronic control component 400, so that the electronic control component 400 and the fresh air module 200 are physically isolated.

[0042] In one embodiment, the partition 110 and the panel 120 further form a second receiving cavity 140, the first receiving cavity 130 and the second receiving cavity 140 are arranged in a vertical direction, and the outdoor unit module 300 is disposed in the second receiving cavity 140, so that the electronic control component 400 and the outdoor unit module 300 are physically isolated.

[0043] The two embodiments described above—the physical isolation between the electronic control component 400 and the fresh air module 200, and the physical isolation between the electronic control component 400 and the outdoor unit module 300—both reiterate and summarize the core ideas of all the preceding technical solutions, and serve as the fundamental starting point for all the aforementioned refined designs. It is precisely because of this physical isolation foundation of the third accommodating cavity 150 that the convenient installation of the wiring terminal 410, the dual-sealed protection of the main control board 440, and the optimized path of the wiring hole 423 are possible. These features work together to systematically solve the challenges of operational stability, safety, and maintainability of the electronic control component 400 in complex environments (including water, dust, heat, and vibration) while ensuring the high integration and compact structure of the integrated fresh air unit.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
