Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning connection structure and an air conditioner having the same. Background Art

[0002] In household air conditioners, the design of air conditioners increasingly requires novel and varied product appearances, and to meet the personalized needs of consumers. In the prior art, the air conditioner middle frame and other components are designed as an integral whole. If the air conditioner appearance changes, the entire air conditioner middle frame must be changed. The mold manufacturing cost is high, and it is not competitive in the market where consumers have strong personalized needs. Therefore, the air conditioner middle frame and other components are divided into multiple panels for design and card connection. During the design, the mold change of the corresponding part does not affect the normal use of the molds of other parts. While the air conditioner is more fashionable and competitive in the market, it can save costs.

[0003] Since a middle frame or other components are connected by a snap-fit ​​structure, it is convenient for disassembly and assembly during maintenance. However, the snap-fit ​​structure is relatively complex, which causes certain difficulties in production and manufacturing, and increases the manufacturing cost of the mold.

[0004] It can be seen from this that it is necessary to invent an air conditioning connection structure with a simple structure, easy production and manufacturing, and reduced production costs. Summary of the invention

[0005] The technical problem solved by the present invention is that the clamping structure of multiple panels is complicated, which causes certain difficulties in production and manufacturing and increases the manufacturing cost of the mold.

[0006] In order to solve the above problems, the present invention provides an air conditioner connection structure.

[0007] An air conditioner connection structure includes a first plate and a second plate that fit together, and a clip, wherein the clip includes a first wall and a second wall connected at the ends, and the clip is further provided with a slot and / or a hook, and the first plate and the second plate are clipped together by the slot and / or the hook. This arrangement makes the structures of the first plate, the second plate and the clip very simple, so that the corresponding mold structure is also relatively simple, which is convenient for production and manufacturing, and can reduce production costs. In addition, the clip structure is firmly connected, and the clip is not easy to fall off.

[0008] Furthermore, one of the first plate or the second plate is provided with a first hook, and the other of the second plate or the first plate is provided with a second slot. The first hook and the second slot are provided on the first plate and the second plate respectively, so that the clamping member can clamp the first plate and the second plate at the same time, and the first hook and the second slot can be interchanged as needed to meet different usage requirements.

[0009] Furthermore, the ends of the first wall and the second wall are directly connected or connected through a connecting wall, a receiving cavity is formed between the first wall and the second wall, and the edges of the first plate and the second plate that are in contact with each other are inserted into the receiving cavity. In this arrangement, the clamping member is a double-layer structure, covering the edges of the first plate and the second plate, which can play a good limiting role, and the outer tube is neat and beautiful.

[0010] Furthermore, the first wall is provided with a first slot, which is a through slot that runs through the first wall, and is engaged with the first hook. In this arrangement, the first slot is a through slot, which is easy to produce, and the first hook can extend out of the first slot, which can make the connection of the connector stable and not easy to fall off.

[0011] Furthermore, a second hook is provided on the second wall, the second hook protrusion is provided in the accommodating cavity, and the second hook is engaged with the second slot. This arrangement can ensure that after the clamping piece is installed, the directions of the two hooks are consistent, and the clamping piece can be connected stably and not easily fall off.

[0012] Furthermore, the first plate includes a first recessed portion, which is disposed on a side of the first plate away from the second plate, and one of the first wall or the second wall is embedded in the first recessed portion. In this arrangement, the first recessed portion serves as a limit guide when the clamping member is clamped, and the clamping member does not interfere with other components, so that the connection can be smooth and beautiful.

[0013] Furthermore, the second plate includes a second recessed portion, which is arranged on a side of the second plate away from the first plate, and the second wall or the other of the first walls is embedded in the second recessed portion. In this arrangement, the second recessed portion serves as a limiting guide when the clamping member is clamped, and the clamping member does not interfere with other components, so that the connection can be smooth and beautiful.

[0014] The first recess is provided with a second slot, and the second recess is provided with a first hook. This arrangement enables the connector to be embedded in the first recess and the second recess when connected to the first plate and the second plate.

[0015] The first wall is provided with a gripping portion, which is folded toward a side away from the second wall and is arranged at an angle with the vertical direction, and the angle a is 0 to 90 degrees. This arrangement can facilitate the application of force by the hand during installation, so as to facilitate the insertion of the clamping part; during disassembly, the hand applies force to increase the distance between the first wall and the second wall, so as to facilitate the detachment of the clamping part.

[0016] Compared with the prior art, the air conditioning connection structure described in the present invention has the following advantages:

[0017] (1) The air conditioner connection structure of the present invention has a simple structure, a tight connection, is not easy to fall off, and is easy to install and disassemble, which is convenient for the maintenance of the air conditioner;

[0039] Further, such as Figure 4 and 6As shown, the clamping member 3 is made of a material with certain elasticity and hardness, such as plastic, resin, or metal, and includes a first wall 31, a second wall 32 and a connecting wall 33. The first wall 31 and the second wall 32 are vertically arranged and parallel to each other. The connecting wall 33 connects the end of the first wall 31 and the end of the second wall 32. The first wall 31, the second wall 32 and the connecting wall 33 together form an accommodating cavity 34. The first wall 31 and the second wall 32 form an opening away from the connecting wall 33. The first plate 1 is inserted into the accommodating cavity 34 from the first recess 11 and the second plate 2 is inserted into the accommodating cavity 34 from the second recess 21, so that the first wall 31 is embedded in the first recess 11 or the second recess 21, and the second wall 32 is embedded in the second recess 21 or the first recess 11. In this embodiment, the first wall 31 is embedded in the second recess 21, and the second wall 32 is embedded in the In the first recess 11, the plane of the first wall 31 away from the accommodating cavity 34 is a first surface 313, and the first surface 313 is aligned with the second plate inner surface 24, or is slightly concave in the second plate inner surface 24.

This arrangement serves to abut against fingers when the clip 3 is installed, and is convenient for the fingers to apply force in the direction of movement of the clip 3. When the clip 3 is disassembled, it is convenient for the fingers to apply force in the direction away from the plate, so that the first slot 311 is disengaged from the first hook 211; a chamfered portion 322 is provided at the end of the second wall 32, and the chamfered portion 322 is arranged on the inner side of the accommodating cavity 34, which can serve as a guide when the clip 3 is installed, and is convenient for the fingers to apply force in the direction away from the plate during disassembly, so that the second hook 321 is disengaged from the second slot 111.

[0042] More specifically, the thickness of the first plate 1 at the first recess 11 is H1, the thickness of the second plate 2 at the second recess 21 is H2, the distance between the first wall 31 and the second wall 32 constituting the accommodating cavity 34 is H, and after the first plate 1 and the second plate 2 are attached, H1+H2≤H, preferably, H1+H2=H, so that after the first plate 1 and the second plate 2 are inserted into the accommodating cavity 34, it is convenient to disassemble the clamping member 3 and ensure that the clamping member 3 has a certain elasticity; the height of the second hook 321 is L, and the second clamping groove The height of 111 is L1, L≤L1, and L1≤H1. This setting ensures that after the second hook 321 is inserted into the second slot 111, the clamping member 3 can fit well with the first plate 1 and the second plate 2, and the connection is more stable; the width of the clamping member 3 is D, the width of the first recess 11 is D1, and the width of the second recess 21 is D2, D1=D2, and D≤D1, preferably, D=D1, the second recess 21 plays a limiting and guiding role on both sides of the first wall 31, and the first recess 11 plays a limiting and guiding role on both sides of the second wall 32.

[0043] When the first plate 1, the second plate 2 and the clamping member 3 are connected, the first plate fitting surface 13 and the second plate fitting surface 23 are fitted together, the first plate top surface 10 and the second plate top surface 20 are aligned, and the first recess 11 is aligned with the second recess 21 in width direction, the first top surface 12 and the second top surface 22 are aligned, the openings of the first wall 31 and the second wall 32 on the clamping member 3 are downward, the first wall 31 faces the second recess 21, and the second wall 32 faces the first recess 11, and the clamping member 3 is pushed downward with force, the first wall 31 is embedded in the second recess 21, and the second wall 32 is embedded in the first recess 11, until the first hook 211 is inserted into the first slot 311, and the second hook 211 is inserted into the first slot 311. The hook 321 is inserted into the second slot 111, and the first top surface 12 and the second top surface 22 abut against the inner top surface 331 of the connector 3. Preferably, the chamfered portion 322 maintains a certain gap with the lower edge of the first recess 11 to accommodate a finger, and the holding portion 312 maintains a certain gap with the lower edge of the second recess 21 to accommodate a finger. The holding portion 312 protrudes from the inner surface 24 of the second plate, the first surface 313 is aligned with the inner surface 24 of the second plate, the second surface 323 is aligned with the outer surface 14 of the first plate, and the outer top surface 332 is aligned with the top surface 10 of the first plate and the top surface 20 of the second plate.

[0044] When the clamping member 3 is disassembled, a finger is placed in the gap between the lower edge of the second recess 21 and the holding portion 312, and a force is applied to the holding portion 312. Due to the elastic effect, the distance between the first wall 31 and the second wall 32 becomes larger, so that the first hook 211 is disengaged from the first slot 311, and the clamping member 3 can be pulled out upward. Alternatively, another finger is placed in the gap between the lower edge of the first recess 11 and the chamfered portion 322, and a force opposite to the holding portion 312 is applied to the chamfered portion 322. At this time, the distance between the first wall 31 and the second wall 32 is further increased, and the second hook 321 is disengaged from the second slot 111, making it easier to pull out the clamping member 3 upward.

[0045] Embodiment 2 is improved on the basis of embodiment 1, such as Figure 7 , Figure 8 and Fig. 9 As shown, the second card slot 111 is a square through slot, and the second hook 321 is a triangular protrusion. When clamped, the upper edge of the second hook 321 fits with the upper edge of the second card slot 111 to limit the clamping. The lower inclined surface of the second hook 321 plays a guiding role when the clamping component 3 is installed. This setting makes the connection between the clamping component 3 and the first plate 1 and the second plate 2 more stable. When the clamping component 3 is disassembled, it is necessary to apply opposite forces to the holding portion 312 and the chamfered portion 322 at the same time, which is more convenient to pull out the clamping component 3. Other settings are the same as those in Example 1.

The direction of the second hook 321 is opposite to that in the second embodiment. When engaged, the lower edge of the second hook 321 fits with the lower edge of the second slot 111 to limit the engagement. The upper inclined surface of the second hook 321 plays a guiding role when the engaging member 3 is disassembled. This arrangement makes it easier to disassemble the engaging member 3. Only force needs to be applied to the gripping portion 312 to pull it out in a direction roughly parallel to the inclined surface of the first hook 211 or the second hook 321. Other arrangements are the same as those in the first embodiment.
