Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a constant temperature and humidity vertical air conditioner indoor unit. Background Art

[0002] With the widespread use of air conditioning systems, their performance and efficiency have become the focus of users. However, in the existing technology, water management and production efficiency issues of air conditioning indoor units still face significant challenges, especially in terms of water vapor control and insulation measures in the heat exchange area.

[0003] 1. Limitations of the water tray design

[0004] In the design of traditional air conditioner indoor units, the size and layout of the water tray are often the weak links in the design. The main function of the water tray is to collect condensed water generated by components such as heat exchangers, humidifier barrels, and electronic control boxes during operation, and ensure that the water can be effectively discharged to avoid dripping. However, since the area of ​​the water tray is not enough to fully cover the above heat exchange area, some water droplets formed by condensation of water vapor cannot be captured in time, causing dripping inside or around the indoor unit. This problem not only affects the normal operation of the air conditioning system, but may also have adverse effects on the indoor environment, such as breeding mold and damaging furniture.

[0005] 2. Limitations of insulation measures in heat exchange areas

[0006] In order to reduce the water vapor generated in the heat exchange area (including capillaries and internal pipes) under alternating hot and cold environments, the prior art usually takes measures to increase thermal insulation materials. Although this alleviates the water vapor problem to a certain extent, it also introduces new challenges. First, the additional insulation process significantly increases the production complexity and time consumption of the air-conditioning indoor unit, and reduces the overall production efficiency. Secondly, the use of thermal insulation materials not only increases the cost of the product, but may also increase the overall weight and volume of the air-conditioning indoor unit, which is not conducive to transportation and installation. In addition, there is also a method of tilting the heat exchanger to facilitate the reception of the generated water vapor, such as the air-conditioning equipment disclosed in patent CN201920862330.X, but it can only collect water vapor from the heat exchanger, and cannot guarantee that the water vapor from other heat exchange structures can be received and discharged in time.

[0007] In view of the above problems, while the existing technology improves the performance of the air-conditioning system, it also exposes deficiencies in water management and production efficiency. Summary of the invention

[0008] The utility model provides a constant temperature and humidity vertical air conditioner indoor unit to solve the problems of the prior art. The water vapor and water droplets generated in the heat exchange area can be received in a water receiving tray and then discharged in time through the water receiving tray. Therefore, the structure of the heat exchange area does not need to increase the thermal insulation material, thus reducing the production cost and improving the production efficiency.

[0034] This embodiment provides a constant temperature and humidity vertical air conditioner indoor unit, such as Figures 1 to 8 , including a frame, characterized in that: it also includes a fan 13 component, a heat exchange component, a humidification component, a drainage component and an electronic control component installed on the frame, the drainage component includes a water receiving tray 1, the humidification component includes a humidification barrel 2, the heat exchange component, the humidification barrel 2 and the electronic control component are all located above the water receiving tray 1, the heat exchange component is obliquely arranged above the humidification component and the electronic control component; the water receiving tray 1 is arranged obliquely to the horizontal plane.

[0035] Specifically, the area of ​​the water receiving tray 1 is sufficient to cover the heat exchange component, humidification component and electronic control component above it, that is, the water droplets generated by the components in the heat exchange area can fall into the water receiving tray 1 and be discharged to the drainage system in time by the water receiving tray 1.

[0036] The bottom of the water receiving tray 1 is tilted. Figure 4 As shown, it can be Figure 4 The left side of the slant is to the right, or it can be tilted from right to left; Figure 3 In the direction shown, it can be tilted from left to right or from right to left. It can be understood that the water receiving tray 1 only needs to be tilted in one direction to make the collected water flow in one direction. Furthermore, in the tilted direction, a drain port 5 is provided so that the collected water can flow to the drain port 5 until it is discharged. The tilted arrangement of the water receiving tray 1 of this embodiment allows only one drain port 5 to be provided, which simplifies the number of drain ports 5, is convenient for users to take over, is easy to operate, and has a simpler appearance.

[0037] Further, the assembly method of the water receiving tray 1 is to install a mounting frame 3 on the frame, the mounting frame 3 is in the shape of a cube, the mounting frame 3 is installed on the frame and is provided with a cavity, the water receiving tray 1 is provided with a support plate 4, and optionally, the water receiving tray 1 is provided with support plates 4 at least at both ends, and support plates 4 can also be provided on all sides. During assembly, the water receiving tray 1 is assembled into the cavity, and the support plate 4 of the water receiving tray 1 abuts against the surroundings of the mounting frame 3, such as Figure 4 and Figure 7 As shown, that is, the mounting frame 3 is fixed on the frame, and the water receiving tray 1 is directly placed on the mounting frame 3, so that the water receiving tray 1 can be removed and cleaned at any time, which is more convenient to use.

[0038] The structure of the humidification component of this embodiment is as follows Figure 4 and Figure 6 As shown, it includes a humidifying barrel 2 and a water collecting tray 6, the water collecting tray 6 is installed on the frame, the water outlet of the humidifying barrel 2 is located above the water collecting tray 6, and the water outlet of the water collecting tray 6 is located above the water receiving tray 1, wherein the shape of the water collecting tray 6 is similar to an L-shape, so after the water collecting tray 6 is installed on the frame, the humidifying barrel 2 is fixed to the water collecting tray 6, and the water discharged from the humidifying barrel 2 can fall into the water collecting tray 6, and then be uniformly discharged to the water receiving tray 1 from the water outlet of the water collecting tray 6, which can ensure that the water generated by the humidifying barrel 2 can accurately fall into the water receiving tray 1.

[0039] The heat exchange component of this embodiment is as follows Figure 1 , Figure 2 and Figure 8 As shown, it includes a heat exchanger 7, a heater 8 and a guide plate 9, both ends of the guide plate 9 are installed on the frame, one end of the heat exchanger 7 is installed on the guide plate 9, and the other end of the heat exchanger 7 is installed on the frame. The heat exchanger 7 is inclined, and the heater 8 is installed on the heat exchanger 7.

Therefore, the heat exchanger 7 is inclined, and the water droplets generated during the heat exchange process can flow to the guide plate 9 along the inclined direction of the heat exchanger 7, and then be guided to the water receiving tray 1 by the guide plate 9. Furthermore, the guide plate 9 is also inclined, such as Figure 8 As shown, a guide port 10 is further opened in the inclined direction of the guide plate 9, so that water falling into the guide plate 9 can flow to the guide port 10 along the inclined direction of the guide plate 9, and then flow out to the water receiving tray 1 through the guide port 10. It can be understood that a first baffle 16 is arranged around the guide plate 9, leaving only one guide port 10 for water to flow out. The setting of the first baffle 16 can prevent water from flowing out from other positions, thereby ensuring that water can accurately flow into the water receiving tray 1.
