[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present utility model.

[0036] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between the embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] The present utility model provides a pipe joint structure for an air conditioner. The air conditioner includes an outdoor unit and an indoor unit. The refrigerant pipes are respectively connected to the indoor and outdoor units of the air conditioner. The air conditioner can be a split-type air conditioner that facilitates users to install it by themselves. The refrigerant pipes are connected to the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. Thus, when the user installs the equipment by themselves, they only need to fix the indoor and outdoor units of the air conditioner respectively, without the need to assemble the refrigerant pipes and fill the refrigerant, thereby reducing the installation difficulty and enabling users to install it by themselves.

[0039] Moreover, for such a split-type air conditioner that facilitates users to install it by themselves, the compressor can be arranged in the indoor unit of the air conditioner, thereby reducing the weight of the outdoor unit and facilitating the installation of the outdoor unit in the outdoor space. Correspondingly, in order to reduce the noise generated by the compressor, a noise reduction structure needs to be arranged for the compressor. However, this design is not limited thereto. In other embodiments, the air conditioner of the present utility model can also be a common split-type air conditioner or an integrated air conditioner.

[0040] The air conditioner further includes a flexible connection component. The flexible connection component includes refrigerant pipes, an indoor drain pipe, and connection wires. The refrigerant pipes, the indoor drain pipe, and the connection wires are respectively connected to the indoor and outdoor units of the air conditioner. In other embodiments, the flexible connection component includes a sleeve, and the refrigerant pipes, the indoor drain pipe, and the connection wires are arranged through the sleeve, so that the refrigerant pipes, the indoor drain pipe, and the connection wires are configured as a whole, facilitating the connection between the indoor and outdoor units of the air conditioner. Among them, the sleeve can also be configured as a wire structure, and the wire structure is wound around the outer periphery of the refrigerant pipes, the indoor drain pipe, and the connection wires to form a sleeve.

[0041] In addition, the air conditioner further includes an outdoor drain pipe. The outdoor drain pipe is connected to the casing 3 of the outdoor unit of the air conditioner, so that the condensed water generated by the indoor unit of the air conditioner is discharged into the outdoor unit of the air conditioner through the indoor drain pipe, and then the condensed water of the outdoor unit of the air conditioner is discharged from the air conditioner through the outdoor drain pipe. In order to facilitate the installation of the outdoor drain pipe and the casing 3, the pipe joint structure is fixedly installed on the casing 3 and is hermetically connected to the casing 3. The outdoor drain pipe is connected to one end of the pipe joint structure located outside the casing 3, thereby realizing the sealed connection between the outdoor drain pipe and the casing 3. The end of the pipe joint structure located inside the casing 3 is used to connect to the indoor drain pipe or the internal space of the casing 3, so that the outdoor drain pipe drains water for the outdoor unit of the air conditioner. And in order to reduce the accumulation of condensed water in the outdoor unit of the air conditioner, the casing 3 includes a chassis 32, and the pipe joint structure is installed on the chassis 32 or installed at a position of the casing 3 close to the chassis 32. In other embodiments, the pipe joint structure can also be installed at other positions of the casing 3. In other embodiments, the pipe joint 1 can also be installed on the casing 3 of the indoor unit of the air conditioner, and the indoor drain pipe is connected to the pipe joint structure to drain water for the indoor unit of the air conditioner.

[0042] Among them, the indoor drain pipe discharges the condensed water in the air conditioner indoor unit to the casing 3 of the air conditioner outdoor unit, and then the outdoor drain pipe discharges the condensed water in the casing 3. However, the discharge path of the condensed water in the air conditioner outdoor unit is not restricted. For example, the indoor drain pipe can discharge the condensed water in the air conditioner indoor unit to the outdoor heat exchanger in the air conditioner outdoor unit to assist the outdoor heat exchanger in dissipating heat in the refrigeration mode of the air conditioner, and then drip onto the chassis 32 of the outdoor unit casing 3, and then flow to the outdoor drain pipe through the chassis 32; it can also be directly discharged to the chassis 32 of the outdoor unit casing 3 and then flow to the outdoor drain pipe through the chassis 32. At this time, the pipe joint structure is directly connected to the inside of the casing 3; it can also be directly connected to the outdoor drain pipe and directly discharged through the outdoor drain pipe. At this time, the pipe joint structure is directly connected to the outdoor drain pipe, or connected to the outdoor drain pipe through a connecting pipe; that is, as long as the condensed water in the air conditioner indoor unit can pass through the casing 3, it is not necessarily required to make the condensed water in the air conditioner indoor unit stay in the casing 3.

[0043] Please refer to Figures 1 to 9 , in an embodiment of the present invention, the pipe joint structure includes:

[0044] A pipe joint 1, one end of which is inserted into the mounting hole 31 and installed on the inner side of the edge of the mounting hole 31, the other end is used to connect the drain pipe of the air conditioner, and an annular abutting portion 11 is provided on the outer periphery of the pipe joint 1, and the annular abutting portion 11 is relatively spaced on the outer side of the casing 3; and

[0045] An annular seal 2 is sleeved on the pipe joint 1 and clamped between the annular abutting portion 11 and the casing 3, and the annular seal 2 is provided with a deformation groove 21 extending in the circumferential direction.

[0046] Specifically, a mounting hole 31 is provided on the casing 3. One end of the pipe joint 1 is inserted into the mounting hole 31 and clamped with the inner side of the edge of the mounting hole 31, and the other end is connected to the drain pipe, so as to realize the connection between the drain pipe and the inside of the casing 3 and facilitate the installation of the drain pipe. And in order to ensure the seal between the pipe joint 1 and the mounting hole 31, an annular abutting portion 11 is provided on the outer periphery of the pipe joint 1, and the annular abutting portion 11 is relatively spaced on the outer side of the casing 3. The annular seal 2 is sleeved on the pipe joint 1 and clamped between the annular abutting portion 11 and the casing 3. The annular seal 2 seals between the mounting hole 31 and the annular abutting portion 11, so as to further seal the mounting hole 31 and reduce the possibility of water leakage between the pipe joint 1 and the mounting hole 31.

[0047] However, in the prior art, the annular seal 2 is often directly configured as a solid structure such as a sealing gasket or a sealing ring. The operator pushes the pipe joint 1 toward the housing 3, so that the annular abutment portion 11 presses the annular seal 2, causing the annular seal to deform and completing the clamping of the pipe joint 1 with the edge of the mounting hole 31. Therefore, the thickness of the annular abutment portion 11 requires a high degree of precision. If the thickness of the annular seal 2 is too large, a large pushing force is required to complete the installation, which is inconvenient; if the thickness of the annular seal 2 is too small, it is not conducive to the sealing of the annular seal 2. Therefore, in this solution, the annular seal 2 is provided with a deformation groove 21 extending along the circumferential direction, thereby increasing the deformation rate of the annular seal 2 under the action of extrusion, thereby reducing the thickness requirement of the annular seal 2 during installation, so that the user only needs to use a small force to complete the sealing of the annular seal 2 and the pipe joint 1, thereby improving the sealing performance and installation convenience of the annular seal 2.

[0048] Among them, preferably, the deformation groove 21 is provided on the side facing the housing 3, or on the side facing the annular abutment portion 11, so as to reduce the local thickness of the annular seal 2, thereby increasing the local deformation of the annular seal 2, and thereby increasing the deformation rate of the annular seal 2 under extrusion. In other embodiments, the deformation groove 21 is directly provided on the inner side of the annular seal 2. And because the annular seal 2 can undergo a large degree of deformation during the installation process, before installation, the inner periphery of the annular seal 2 can be set with a gap from the outer periphery of the pipe joint 1. During installation, the axial sides of the annular seal 2 are subjected to extrusion deformation, and while its axial thickness is reduced, its circumferential size gradually increases, so that the inner periphery of the annular seal 2 abuts against the outer periphery of the pipe joint 1, thereby sealing the outer periphery of the pipe joint 1 while reducing the possibility of displacement of the annular seal 2.

[0049] See also Figures 5 to 8 In an embodiment of the present invention, a sealing rib 22 is provided on the side of the annular seal 2 facing the housing 3, and a deformation groove 21 is formed on the side of the annular seal 2 facing away from the sealing rib 22. Specifically, the sealing rib 22 is provided on the side of the annular seal 2 facing the housing 3, that is, the side of the annular seal 2 facing the housing 3 is partially axially protruded, thereby increasing the local thickness of the annular seal 2. Compared to increasing the overall thickness of the annular seal 2, this solution can reduce the installation force required to complete the seal between the annular seal 2 and the pipe joint 1, thereby improving the sealing performance of the annular seal 2 and the ease of installation. The deformation groove 21 is provided on the side of the annular seal 2 facing away from the sealing rib 22, that is, the deformation groove 21 and the sealing rib 22 are respectively arranged on two opposite axial sides of the annular seal 2, so that the side of the annular seal 2 facing the casing 3 can improve the sealing performance of the periphery of the mounting hole 31, and the side of the annular seal 2 facing away from the casing 3 is more likely to deform, thereby further improving the sealing performance and installation convenience of the annular seal 2.

[0050] Furthermore, the sealing rib 22 and the deformation groove 21 are axially overlapped; that is, the diameter of the ring formed by the sealing rib 22 is the same as the diameter of the ring formed by the deformation groove 21. Since the thickness of the annular seal 2 at the sealing rib 22 is the thickest, the compression amount is the largest during installation, and the corresponding compression resistance is also the largest. Therefore, the overlapping arrangement of the deformation groove 21 and the sealing rib 22 helps to reduce the maximum thickness of the annular seal 2, thereby further improving the sealing performance and installation convenience of the annular seal 2. In other embodiments, the sealing rib 22 and the deformation groove 21 are not axially overlapped; or, the sealing rib 22 and the deformation groove 21 are axially offset.

[0051] To reduce the elastic deformation amount at the sealing rib 22 of the annular seal 2, in the embodiment of the present invention, please refer to Figure 5 and Figure 8 , along the direction close to the housing 3, the width of the sealing rib 22 is set to become smaller. Specifically, the smaller the thickness of the sealing rib 22, the easier it is to deform during its extrusion process, and thus the easier it is to install. However, if the overall thickness is small, it is difficult to ensure the sealing stability at the sealing rib 22. Therefore, along the direction close to the housing 3, the width of the sealing rib 22 is set to become smaller, so as to ensure both the sealing stability and the installation convenience.

[0052] Preferably, the cross-section of the sealing rib 22 along the radial direction of the annular seal 2 is triangular. In other embodiments, the cross-section of the sealing rib 22 along the radial direction of the annular seal 2 is trapezoidal.

[0053] Furthermore, please refer to Figure 8 , along the direction close to the housing 3, the groove width of the deformation groove 21 is set to become smaller, so that the two sides of the deformation groove 21 in the radial direction can be regarded as two locally connected sealing rings. As the extrusion force increases, the deformation groove 21 also provides sufficient avoidance space for the deformation of the two sealing rings, thus facilitating the deformation of the annular seal 2. Preferably, the cross-section of the sealing rib 22 along the radial direction of the annular seal 2 is triangular or trapezoidal.

[0054] Please refer to Figure 9, in an embodiment of the present utility model, a blocking portion is provided on the outer edge of the annular abutting portion 11, and the blocking portion abuts against the outer peripheral side of the annular seal 2. During installation, both axial sides of the annular seal 2 are squeezed and deformed. While its axial thickness decreases, its circumferential dimension gradually increases, causing the outer diameter of the annular seal 2 to gradually increase, making it possible for the annular seal 2 to partially escape from the annular abutting portion 11, affecting the seal between the pipe joint 1 and the mounting hole 31. Therefore, a blocking portion is provided on the outer edge of the annular abutting portion 11, and the blocking portion abuts against the outer peripheral side of the annular seal 2, thereby reducing the possibility of the annular seal 2 escaping from the annular abutting portion 11. In other embodiments, it is also possible to set the outer circumference of the annular abutting portion 11 to be much larger than the outer peripheral side dimension of the annular seal 2, thereby reducing the possibility of the annular seal 2 partially escaping from the annular abutting portion 11.

[0055] Preferably, the blocking portion is configured as an annular rib 111 provided on the outer circumference of the annular abutting portion 11 to ensure the blocking effect of the blocking portion. And the annular rib 111 is integrally formed with the annular abutting portion 11, which can not only ensure the stable installation of the annular seal 2 but also facilitate the installation of the pipe joint structure. In other embodiments, the blocking portion can also be configured as a blocking portion, and the blocking portions are arranged at intervals along the outer circumference of the annular abutting portion 11.

[0056] And to ensure the sealing effect of the annular seal 2, in an embodiment of the present utility model, along the axis of the annular seal 2, the height of the blocking portion is less than the thickness of the annular seal 2. Specifically, if the height of the blocking portion is less than the thickness of the annular seal 2, during installation, when the annular seal 2 is not subjected to extrusion or sufficient extrusion force, it is difficult to ensure the sealing effect between the annular seal 2, the pipe joint 1, and the mounting hole 31. Therefore, the height of the blocking portion is set to be less than the thickness of the annular seal 2. Preferably, the height of the blocking portion is less than the height of the annular seal 2 after installation, so as to ensure that the annular seal 2 is subjected to sufficient extrusion force during installation, thereby ensuring the sealing effect of the annular seal 2.

[0057] Please refer to Figure 1 、 Figure 2 and Figure 9, in an embodiment of the present utility model, a water passing port 12 and a plurality of buckles 13 are provided on the circumferential side of one end of the pipe joint 1 inserted into the mounting hole 31. The water passing port 12 is used for the condensed water in the air conditioner to flow out, and the plurality of buckles 13 are clamped to the inner side of the edge of the mounting hole 31. Specifically, a water passing port 12 is provided on the circumferential side of one end of the pipe joint 1 inserted into the mounting hole 31, and the water passing port 12 communicates with the inner circumferential side of the pipe joint 1. Since the pipe joint 1 is partially inserted into the air conditioner, the water passing height of the pipe joint 1 must be greater than the height of the air conditioner chassis 32. Once water enters the outdoor unit of the air conditioner, some water will accumulate on the chassis 32 and it is difficult to drain. Therefore, setting the water passing port 12 can effectively reduce the water passing height of the pipe joint 1, thereby reducing the possibility of water remaining on the chassis 32. The buckle 13 is used to clamp the pipe joint 1 to the casing 3, thus facilitating the installation of the pipe joint 1.

[0058] In this embodiment, the buckle 13 and the annular abutting portion 11 are respectively provided on the inner and outer sides of the casing 3, so that the annular abutting portion 11 and the annular seal 2 jointly press the chassis 32 to ensure that the buckle 13 clamps the edge of the mounting hole 31, thereby ensuring the installation stability of the pipe joint 1.

[0059] The buckle 13 can be provided at the edge of the mounting hole 31, so that the water passing port 12 can provide an avoidance function for the buckle 13, and there is no need to provide an avoidance notch at the periphery of the installation. Thus, it is convenient for the processing of the mounting hole 31. During actual installation, only need to insert the pipe joint 1 into the mounting hole 31. When the buckle 13 passes through the installation, the buckle 13 can be clamped to the edge of the mounting hole 31, thus facilitating the installation of the pipe joint 1.

[0060] In an embodiment of the present utility model, a plurality of buckles 13 are provided at one end of the pipe joint 1 at intervals in the circumferential direction. The plurality of buckles 13 are clamped to the edge of the mounting hole 31, and the interval between any two adjacent buckles 13 forms a water passing gap, which is used for the condensed water on the chassis 32 to flow out; the outdoor drain pipe is connected to the other end of the pipe joint 1. However, at this time, a avoidance notch needs to be provided at the edge of the mounting hole 31 corresponding to each buckle 13. After the buckle 13 passes through the corresponding avoidance notch, rotate the pipe joint 1, and the buckle 13 can be clamped to the edge of the mounting hole 31.

[0061] The present utility model also proposes an air conditioner, which includes a pipe joint structure. The specific structure of the pipe joint structure refers to the above embodiment. Since this air conditioner adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one.

[0062] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
