Description

Technical Field

[0001] This utility model relates to the technical field of air conditioning equipment, and in particular to a base structure, an independent air conditioning accessory shell, and an air conditioning secondary cooling and heating device. Background Technology

[0002] An air conditioning system consists of two parts: an outdoor unit and an indoor unit. During operation, the refrigerant is first throttled at the outdoor unit and then transported to the indoor unit through pipes, where it exchanges heat with the indoor air to achieve cooling or heating. However, in some practical applications, due to the large size of the outdoor unit and space constraints, it often needs to be installed far from the indoor unit. In this case, the refrigerant exchanges heat with the external environment during its journey through the pipes to the indoor unit. This can cause the refrigerant temperature to rise or fall, affecting the cooling effect and preventing it from reaching its ideal cooling state. To solve this problem, it is necessary to add a secondary cooling / heating device, while ensuring that this device is compact and suitable for installation in confined spaces. Utility Model Content

Detailed Implementation

[0020] This utility model provides a base structure, an independent air conditioner accessory housing, and an air conditioner secondary cooling and heating device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0022] Please see Figure 1The first aspect of this utility model provides a base structure, including a base plate 1 and a first fixing member 11, a plurality of second fixing members 12, and a plurality of third fixing members 13 fixed on the base plate 1; the base plate 1 is also provided with a front wall 14, a right wall 15, and a rear wall 16 connected in sequence; the first fixing member 11 and the second fixing member 12 have the same height and are greater than the height of the third fixing member 13; the length of the first fixing member 11 is greater than the length of the second fixing member 12 and is connected to the inner side of the right wall 15; the plurality of second fixing members 12 are disposed in the middle of the base plate 1, away from the first fixing member 11; the first fixing member 11 and the second fixing member 12 are used to fix the circuit board 5; the third fixing member 13 is used to fix the pipe clamp. Specifically, the base structure of this embodiment is used to assemble an air conditioner secondary cooling and heating device. A double-layer design can be formed on the basis of the base structure, the base plate 1 is used to install the refrigerant circuit assembly 4 of the air conditioner secondary cooling and heating device, while the first fixing member 11 and the second fixing member 12 are used to install the circuit board 5, forming a double-layer structure with the refrigerant circuit assembly 4 below and the circuit board 5 above. The overall structure is compact and small in size, making it suitable for installation in confined spaces. Furthermore, the first fixing member 11 is relatively long and connects to the inner side of the right wall 15, providing a larger support area for a more secure fixation of the circuit board 5. The relatively large size of the first fixing member 11, and its placement at the connection point with the inner side of the right wall 15, prevents it from being installed in the middle of the base plate 1, which would interfere with the installation of the refrigerant circuit assembly 4; and its placement away from the left side of the base plate 1 avoids obstructing the external introduction of the refrigerant circuit assembly 4's piping. Specifically, multiple second fixing members 12 are arranged in a triangular pattern with the first fixing member 11, providing better support for the circuit board 5. The base structure in this embodiment has an opening on the left side to facilitate the subsequent installation of the refrigerant circuit assembly 4's piping. This also allows piping and wiring to exit from one side for easier management. The piping in the refrigerant circuit assembly 4 requires pipe clamps for fixation, and the third fixing member 13 provides mounting points for the pipe clamps in the middle of the base plate 1. The refrigerant circuit assembly 4 is used to throttle the refrigerant, achieving secondary refrigeration.

The fourth fixing member 17 has multiple mounting holes for fixing pipe clamps. The multiple mounting holes are arranged sequentially along the length of the fourth fixing member 17. The fourth fixing member 17 is used to fix the inlet and outlet pipes in one area for easy management. Specifically, the pipe clamps are connected to the fourth fixing member 17 by screws.

[0024] Please see Figure 1In one embodiment, a wire clamp 18 is provided on the front wall 14, right wall 15, or rear wall 16. The wire clamp 18 is used to clamp the connecting wires of the circuit board 5. The circuit board 5 is connected to the valve body on the refrigerant circuit assembly 4 through the connecting wires. The middle section of these connecting wires is clamped on the front wall 14, right wall 15, or rear wall 16, thereby making the internal wiring clear.

[0025] Please see Figure 2 In one embodiment, the wire clamp 18 includes a fixing part 181 and a clamping part 182; the fixing part 181 is fixedly connected to the front wall 14, the right wall 15, or the rear wall 16; the clamping part 182 abuts against the front wall 14, the right wall 15, or the rear wall 16; the clamping part 182 is provided with a slot 183; the slot 183 extends along the length direction of the clamping part 182. The fixing part 181 and the clamping part 182 are elastically connected. Specifically, the connecting wire can first pass through the slot 183 from the front and then come out from the back of the clamping part 182, thereby clamping more securely.

[0026] Please see Figure 1 In one embodiment, the top inner sides of the front wall 14 and the rear wall 16 are respectively provided with connecting portions 141; the connecting portions 141 are provided with slots 142; the slots 142 are used to engage with the top cover 2.

[0027] Please see Figure 3 In one embodiment, the slot 142 includes an insertion portion 143 and a locking portion 144; the width of the insertion portion 143 is greater than the width of the locking portion 144. Specifically, the width of the insertion portion 143 is greater than the locking block 21 of the top cover 2; while the width of the locking portion 144 is less than the locking block 21 of the top cover 2, but greater than the connecting piece between the locking block 21 and the top cover 2. In use, the locking block 21 is first inserted into the insertion portion 143, and then moves towards the locking portion 144, while the connecting piece moves into the locking portion 144, and the locking block 21 is locked below the locking portion 144.

[0028] Please see Figure 4 and Figure 5 The second aspect of this utility model provides an independent air conditioner accessory housing, including a top cover 2, a side cover 3, and a base structure as described above; the top cover 2 is detachably connected to the front wall 14 and the rear wall 16 of the base structure; the side cover 3 is disposed on the left side of the base structure and is detachably connected to the front wall 14 and the rear wall 16 of the base structure.

[0030] In summary, this utility model provides a base structure, an independent air conditioner accessory housing, and an air conditioner secondary cooling and heating device. The base structure is a double-layer installation structure, which allows the refrigerant circuit assembly 4 and the circuit board 5 to be installed simultaneously in one housing, resulting in high internal space utilization and a smaller size for the air conditioner secondary cooling and heating device, effectively meeting the installation requirements of small spaces.

[0031] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
