[0002] When an air conditioner is running in cooling or heating mode, the temperature difference between the refrigerant pipes and the outside environment is significant, causing condensation to easily drip from the refrigerant pipes.

The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as limiting the present application.

[0056] The disclosure below provides many different embodiments or examples for implementing different structures of the application. For the sake of simplicity, the description below of a particular embodiment or example does not necessarily include all features of the application. It is intended, however, that the application include all possible combinations of features that would be dependent upon the particular embodiment or example described in the disclosure. It is also contemplated that the application include "generic" embodiments and / or examples that can include, but are not limited to, any and all possible combinations of the various features described in the disclosure. In addition, many of the concepts described in the disclosure can be implemented in different embodiments or examples.

[0057] In the description of embodiments of the present application, the term "and / or" is merely used to describe an associated relationship between associated objects, which means that there can be three relationships, for example, A and / or B, which can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0058] Next, with reference to the accompanying drawings, an air conditioner 2 according to an embodiment of the present application is described.

[0059] As shown in Figures 1-5 The air conditioner 2 includes a refrigerant circulation system, a first water pan 44a, a water beating device 70, and a first pipe water receiving member 80. The refrigerant circulation system includes a condenser 68 and a first refrigerant pipe 34. The first water pan 44a is arranged at the lower side of the condenser 68 and has a water receiving groove 440 and a water beating groove 441. The water receiving groove 440 is in communication with the water beating groove 441. The condenser 68 is arranged adjacent to the water beating groove 441. The water beating device 70 includes a water beating member 71 and a water beating motor 72. The water beating member 71 is arranged in the water beating groove 441. The water beating motor 72 is connected to the water beating member 71 to drive the water beating member 71 to beat the water in the water beating groove 441 to the condenser 68. The first pipe water receiving member 80 is arranged in the first refrigerant pipe 34 or in the first water pan 44a. The first pipe water receiving member 80 is arranged above the water beating motor 72 and has a first water receiving cavity 81 with an open top. The first water receiving cavity 81 is used to receive the condensed water dripping from the first refrigerant pipe 34 towards the water beating motor 72. The first pipe water receiving member 80 is formed with a first water outlet 82 in communication with the first water receiving cavity 81. The first water outlet 82 is opposite to and in communication with the water receiving groove 440.

[0060] It is evident that during the operation of the air conditioner 2, condensation will occur on the outer surface of the first refrigerant pipe 34. At least a portion of the first refrigerant pipe 34 is located above the water pump motor 72. There is a risk that the condensation generated by the first refrigerant pipe 34 will flow towards the water pump motor 72. The first pipe water inlet 80 can collect the condensation dripping from the first refrigerant pipe 34 towards the water pump motor 72, preventing the condensation from directly contacting the water pump motor 72. This reduces the risk of the water pump motor 72 failing due to water immersion, improves the stability of the water pump motor 72's operation, and, due to the aforementioned first pipe water inlet 80, reduces the requirements for the installation position of the water pump motor 72. In related technologies, to reduce the impact of condensation on... Due to the influence of the water pump motor, the first refrigerant line and the water pump motor are usually staggered to prevent condensate from dripping onto the water pump motor. However, this greatly restricts the placement of the water pump motor, thus limiting the internal layout of the air conditioner and hindering the miniaturization design. According to the embodiment of this application, the air conditioner 2 has the first pipe water inlet 80 covered on the upper side of the water pump motor 72, so that the condensate generated by the first refrigerant line 34 can be effectively received by the first pipe water inlet 80. This reduces the restriction on the placement of the water pump motor 72, allowing the layout of the air conditioner 2 to be more compact and facilitating the miniaturization design of the air conditioner 2.

[0061] For example, due to pipe routing limitations, and in order to collect the condensate generated in the first refrigerant pipe 34, the first refrigerant pipe 34 is bent so that the lowest point on the first refrigerant pipe 34 is directly above the water pump motor 72 (e.g., Figure 3 As shown, condensate can flow along the first refrigerant pipe 34 to the pump motor 72. At this time, the first pipe water receiving fitting 80 can be located at the first water receiving tray 44a. In the vertical direction of the air conditioner 2, the first pipe water receiving fitting 80 is located between the pump motor 72 and the first refrigerant pipe 34, and the first water receiving cavity 81 can receive the condensate dripping from the first refrigerant pipe 34 toward the pump motor 72. Of course, the arrangement of the first refrigerant pipe 34 and the first pipe water receiving fitting 80 is not limited to this. For example, the first pipe water receiving fitting 80 can also be located at the first refrigerant pipe 34, with the first refrigerant pipe 34 passing through the first pipe water receiving fitting 80 in the vertical direction, and the first water receiving cavity 81 surrounding the first refrigerant pipe 34. This also allows the first water receiving cavity 81 to receive the condensate generated by the first refrigerant pipe 34.

[0062] It is understood that the first refrigerant pipe 34 can be used to transfer refrigerant during the operation of the refrigerant circulation system. For example, the first refrigerant pipe 34 is connected to the evaporator. Since the temperature difference between the first refrigerant pipe 34 and the external environment is large during operation, condensation is easily generated on the surface of the first refrigerant pipe 34. This application provides a first pipe water receiving component 80 covering the upper side of the water pumping motor 72. The first pipe water receiving component 80 can receive the condensation generated by the first refrigerant pipe 34, so as to reduce the impact of condensation on the water pumping motor 72, thereby improving the stability of the air conditioner 2 operation.

[0063] In addition, a water pumping component 71 is installed inside a water pumping tank 441. A water pumping motor 72 can drive the water pumping component 71 to pump the water in the water pumping tank 441 onto the condenser 68. As a heat exchange device, the condenser 68 typically has a high surface temperature. By pumping water onto the condenser 68 through the water pumping component 71, the water can cover at least a portion of the condenser 68. Utilizing the heat absorption effect of water evaporation, heat is transferred from the condenser 68 to the environment, thereby improving the heat dissipation efficiency of the condenser 68 and thus increasing the working efficiency of the air conditioner 2.

[0064] The first water inlet 80 has a first drain outlet 82 that connects to the first water inlet cavity 81. The first drain outlet 82 is positioned opposite to and connected to the water inlet 440. For example, the first drain outlet 82 may be located above the water inlet 440 or extend downward toward the water inlet 440, so that the water in the first water inlet cavity 81 can flow smoothly into the water inlet 440. This prevents condensate from accumulating in the first water inlet cavity 81, reducing the risk of condensate overflow and preventing condensate from contacting the water pump motor 72 or the first pipe. The components attached to the water receiving part 80 help improve the safety of the water pumping motor 72 or the components near the water receiving part 80 of the first pipeline, thereby improving the stability of the air conditioner 2's operation. The water receiving tank 440 is connected to the water pumping tank 441, so the condensate in the first water receiving chamber 81 can flow through the water receiving tank 440 to the water pumping tank 441, and then the water pumping part 71 will agitate the condensate in the water pumping tank 441 to the condenser 68. The condenser 68 can evaporate the condensate, so the condensate can pass through the first water receiving chamber 81, the water receiving tank 440, the water pumping tank 441 and the condenser 68 in sequence, so that the condensate can be better treated.

[0065] like Figures 1-5 As shown, in some embodiments, a fastener 60 is provided on the first water receiving tray 44a. The fastener 60 passes through the first pipeline water receiving component 80 and the water pump motor 72 to fix both the first pipeline water receiving component 80 and the water pump motor 72 to the first water receiving tray 44a.

[0066] It can be seen that the fastener 60 can simultaneously fix the first pipeline water connection piece 80 and the water hitting motor 72 to the first water connection disc 44a, so that the positions of the first pipeline water connection piece 80 and the water hitting motor 72 are more stable. Even if the air conditioner 2 is subjected to external force, the water hitting motor 72 and the first pipeline water connection piece 80 are not prone to relative movement, the first pipeline water connection piece 80 can always play a protective role on the water hitting motor 72, which facilitates to improve the stability of the water hitting motor 72. At the same time, the first pipeline water connection piece 80 and the first water connection disc 44a are not prone to relative movement, so that the condensed water discharged from the first drain port 82 can be stably received by the water receiving groove 440, which facilitates to improve the stability of the air conditioner 2.

[0067] In addition, the first pipeline water connection piece 80 and the water hitting motor 72 share the fastener 60, and it is not necessary to fix the first pipeline water connection piece 80 and the water hitting motor 72 to the first water connection disc 44a respectively, which reduces the number of fasteners 60 and facilitates the assembly of the staff. It can be understood that the number of fasteners 60 shared by the first pipeline water connection piece 80 and the water hitting motor 72 can be one or more.

[0068] Optionally, the fastener 60 is configured such that the first pipeline water connection piece 80, the water hitting motor 72 and the first water connection disc 44a are detachably arranged. For example, the fastener 60 is a threaded fastener (such as a screw), and the installation and disassembly of the first pipeline water connection piece 80, the water hitting motor 72 and the first water connection disc 44a are more convenient, which facilitates subsequent maintenance and repair, and makes the overall structure more compact and saves space.

[0069] As shown in FIG. 1, Figures 3-5 In some embodiments, a plurality of spaced protruding structures 83 are protruded on the bottom wall of the first water connection cavity 81. When the condensed water on the first refrigerant pipeline 34 drops onto the bottom wall of the first water connection cavity 81, the plurality of spaced protruding structures 83 can play a buffering and dispersing role on the condensed water. For example, when the condensed water drops onto the bottom wall of the first water connection cavity 81, the splashed condensed water will be blocked by the protruding structures 83, so that the condensed water is not easy to splash out of the first water connection cavity 81, so that the condensed water is not easy to contact the water hitting motor 72, which is conducive to improving the stability of the water hitting motor 72.

[0070] It can be understood that the height of the protruding protruding structure 83 is less than the height of the circumferential wall of the first water connection cavity 81, so that the protruding structure 83 is not easy to interfere with other components (such as the first refrigerant pipeline 34) of the air conditioner 2, and the protruding structure 83 does not easily affect the layout of the components in the air conditioner 2, so that the structure of the air conditioner 2 can be more compact. The structure of the protruding structure 83 is not limited, for example, the protruding structure 83 can be hemispherical or columnar, etc.

[0071] Exemplarily, the bottom wall of the first water receiving cavity 81 is provided with a plurality of protruding point structures 83 arranged at intervals, which can be arranged in multiple rows and columns on the bottom wall of the first water receiving cavity 81, or the plurality of protruding point structures 83 are staggered on the bottom wall of the first water receiving cavity 81, so as to better utilize the space in the first water receiving cavity 81.

[0072] As shown in Figures 1-4 some embodiments, the air conditioner 2 further comprises a water level switch 62 arranged on the first water receiving tray 44a and corresponding to the water receiving groove 440, which can detect the water level in the water receiving groove 440. The first pipeline water receiving part 80 has a support portion 84 protruding from the outer circumferential side of the first water receiving cavity 81 and upwardly supporting the water level switch 62. The position where the water level switch 62 cooperates with the first water receiving tray 44a and the position where the water level switch 62 cooperates with the support portion 84 are arranged at intervals.

[0073] It can be seen that the support portion 84 protrudes from the outer circumferential side of the first water receiving cavity 81, so that the support portion 84 does not easily affect the condensate water received by the first water receiving cavity 81, and at the same time, the support portion 84 can better contact the water level switch 62, reducing the requirement for the setting position of the water level switch 62. The support portion 84 upwardly supports the water level switch 62, for example, the support portion 84 supports the lower end of the water level switch 62, which can provide the water level switch 62 with an upward supporting force, and in combination with the cooperation of the water level switch 62 with the first water receiving tray 44a, so that the water level switch 62 has at least two cooperation positions with other components, and the water level switch 62 is not prone to falling off. The position where the water level switch 62 cooperates with the first water receiving tray 44a and the position where the water level switch 62 cooperates with the support portion 84 are arranged at intervals, so that the cooperation of the water level switch 62 with the first water receiving tray 44a is not easily affected by the support portion 84, and at the same time, the above arrangement can increase the support range of the first water receiving tray 44a and the support portion 84 for the water level switch 62. Through the common support of the support portion 84 and the first water receiving tray 44a for the water level switch 62, the possibility of the water level switch 62 falling off is further reduced, so that the water level switch 62 can maintain a relatively stable working state, which is convenient for improving the stability of the operation of the air conditioner 2.

[0074] Among them, the water level switch 62 is arranged on the first water receiving tray 44a and corresponds to the water receiving groove 440, which is beneficial to make the distance between the water level switch 62 and the first pipeline water receiving part 80 closer, the support portion 84 can better contact the water level switch 62, and the size of the support portion 84 does not need to be too large, which is beneficial to reduce the manufacturing cost of the first pipeline water receiving part 80.

[0075] Exemplarily, the water level switch 62 is a double water level switch, and the double water level switch has a large size. If the water level switch 62 is only matched with the first water pan 44a (for example, the water level switch 62 is matched with the first water pan 44a through a snap structure), the part of the water level switch 62 far away from the matching position of the water level switch 62 and the first water pan 44a is prone to sagging, so that the water level switch 62 cannot accurately reflect the water level in the water collecting groove 440. However, the water level switch 62 is supported by the support part 84 and the first water pan 44a together. Even if the water level switch 62 has a large size, the water level switch 62 can also be well supported, the risk of sagging of the water level switch 62 is reduced, and the running stability of the air conditioner 2 is facilitated to be improved.

[0076] As shown in Figures 1-4 some embodiments, the water level switch 62 includes a first water level switch 62a and a second water level switch 62b arranged integrally. The working water level of the first water level switch 62a is lower than that of the second water level switch 62b, and the triggering water level of the first water level switch 62a is lower than that of the second water level switch 62b. For example, when a large amount of water is collected in the water collecting groove 440, the first water level switch 62a is triggered first, and the water level switch 62 transmits a signal to the controller of the air conditioner 2 to reduce the running power of the compressor 66 of the air conditioner 2, so as to reduce the condensed water generated on the first refrigerant pipeline 34. At the same time, the condensed water in the water collecting groove 440 can also be transmitted to the water hitting groove 441, and the water hitting groove 441 can consume part of the condensed water, so as to reduce the water level in the water collecting groove 440, so that the first water level switch 62a is released from triggering, and then the compressor 66 of the air conditioner 2 can run at normal power. If the running power of the compressor 66 is reduced, and the water level in the water collecting groove 440 continues to rise, that is, the amount of condensed water collected in the water collecting groove 440 is greater than the amount of condensed water consumed in the water hitting groove 441, until the second water level switch 62b is triggered. At this time, the condensed water in the first water pan 44a may have the risk of overflowing, the water level switch 62 transmits a signal to the controller of the air conditioner 2, at this time, the air conditioner 2 can be stopped for processing, and a large amount of condensed water will not be generated on the first refrigerant pipeline 34. At the same time, the condensed water in the first water pan 44a can be discharged from the air conditioner 2 through the drain port of the air conditioner 2, so as to reduce the water level in the water collecting groove 440, so that the second water level switch 62b is released from triggering, and the first water level switch 62a is still triggered. At this time, the air conditioner 2 can run at a lower power, so as to further reduce the water level in the water collecting groove 440, until the first water level switch 62a is released from triggering, and then the air conditioner 2 can run in a normal state. It can be seen that, by arranging the first water level switch 62a and the second water level switch 62b, the risk of overflow of the condensed water in the first water pan 44a is reduced, so as to reduce the risk of water bubble failure of each component in the air conditioner 2, so as to improve the running stability of the air conditioner 2.

[0077] The first water level switch 62a and the second water level switch 62b are arranged in sequence along the first horizontal direction, one end of the water level switch 62 in the first horizontal direction is matched with the first water pan 44a, and the other end of the water level switch 62 in the first horizontal direction is abutted by the support portion 84, for example, the support portion 84 abuts the lower end of the water level switch; by arranging the first water level switch and the second water level switch 62b in sequence along the first horizontal direction, the size of the water level switch 62 in the first horizontal direction is larger, and the first water pan 44a and the support portion 84 are respectively supported at both ends of the water level switch 62 in the first horizontal direction, and the first water pan 44a and the support portion 84 can both provide upward supporting force for the water level switch 62, so that the water level switch 62 is not prone to sagging, and the stability of the water level switch 62 in operation is improved. It can be understood that the first horizontal direction is perpendicular to the up-down direction, and the first horizontal direction can be the front-rear direction, the left-right direction, or a horizontal direction inclined relative to the front-rear direction and the left-right direction.

[0078] As shown in Figures 3-5 In some embodiments, the first pipeline water receiving element 80 has a first fixing portion 85 and a second fixing portion 86 arranged oppositely, the first fixing portion 85 and the second fixing portion 86 are protruded from the outer circumferential side of the first water receiving cavity 81, and the first fixing portion 85 and the second fixing portion 86 are respectively fixed with the first water pan 44a by the fastener 60, and the support portion 84 is arranged between the first fixing portion 85 and the second fixing portion 86.

[0079] It can be seen that the first water receiving cavity 81 and the support portion 84 are both located between the first fixing portion 85 and the second fixing portion 86, and the first fixing portion 85 and the second fixing portion 86 are respectively fixed with the first water pan 44a by the fastener 60, so that the first water pan 44a can support the first pipeline water receiving element 80, and the arrangement of the above-mentioned support portion 84 and the first water receiving cavity 81 can prevent the first water receiving cavity 81 and the support portion 84 from deforming and other problems, the support portion 84 can better support the water level switch 62, and the stability of the water level switch 62 in operation is improved.

[0080] The support portion 84 is arranged between the first fixing portion 85 and the second fixing portion 86, so that the support portion 84 does not easily interfere with the fixing of the first fixing portion 85 and the second fixing portion 86 with the first water pan 44a, and provides a larger operation space for the staff, and the assembly efficiency of the first pipeline water receiving element 80 is improved.

[0081] As shown in Figures 1-3As shown, in some embodiments, the refrigerant circulation system further comprises an evaporator and a throttling device 64, the first refrigerant pipeline 34 is connected between the throttling device 64 and the evaporator, the first refrigerant pipeline 34 can be used to transfer refrigerant, and the outer peripheral wall of the first refrigerant pipeline 34 is prone to produce condensed water. The first pipeline water receiving part 80 can receive the condensed water on the first refrigerant pipeline 34, so as to reduce the risk of water bubble failure of the water beating motor 72. The air conditioner 2 is configured to guide the condensed water generated by the evaporator to the water receiving groove 440, and further comprises a second water receiving tray 46. The second water receiving tray 46 is arranged on the lower side of the evaporator. Exemplarily, the condenser described above corresponds to the outdoor heat exchanger of the air conditioner 2, and the evaporator corresponds to the indoor heat exchanger of the air conditioner 2, but is not limited thereto.

[0082] The air conditioner 2 further comprises a driving motor, a water inlet of the driving motor is in communication with the second water receiving tray 46, and a water outlet of the driving motor is in communication with the water receiving groove 440 or the water beating groove 441. The second water receiving tray 46 can receive the condensed water generated during the operation of the evaporator. By arranging the driving motor, the condensed water in the second water receiving tray 46 can flow to the water receiving groove 440 through the driving motor, thereby indirectly flowing to the water beating groove 441, or the condensed water in the second water receiving tray 46 directly flows to the water beating groove 441 through the driving motor, so as to be used by the water beating device 70 to beat the condenser 68 on the condenser 68, thereby facilitating to improve the heat dissipation efficiency of the condenser 68, and further improving the refrigeration or heating effect of the air conditioner 2. In addition, the first water receiving tray 44a and the second water receiving tray 46 are integrated, and the first water receiving tray 44a and the second water receiving tray 46 are formed with a flow guide structure in communication with the first water receiving tray 44a and the water receiving groove 440. The flow guide structure is used to guide the water on the second water receiving tray 46 to the water receiving groove 440. For example, the flow guide structure enables the condensed water to spontaneously flow to the water receiving groove 440 under the action of its own gravity. Through the flow guide structure, the condensed water generated during the operation of the evaporator can be guided to the water receiving groove 440. That is, the condensed water of the evaporator first drops into the second water receiving tray 46, and then the condensed water in the second water receiving tray 46 is guided to the water receiving groove 440 through the flow guide structure. The condensed water in the water receiving groove 440 flows to the water beating groove 441, so as to be used by the water beating device 70 to beat the condenser 68 on the condenser 68, thereby facilitating to improve the heat dissipation efficiency of the condenser 68, and further improving the refrigeration or heating effect of the air conditioner 2.

[0083] It can be understood that the first water pan 44a and the second water pan 46 are integrally arranged, which can reduce the connection points between the first water pan 44a and the second water pan 46, so that the condensed water is not easy to leak out from the gap between the first water pan 44a and the second water pan 46, thereby facilitating to improve the stability of the air conditioner 2 in operation, and the first water pan 44a and the second water pan 46 are integrally designed, which is convenient for processing, for example, the first water pan 44a and the second water pan 46 are formed by injection molding, thereby facilitating to improve the processing efficiency of the first water pan 44a and the second water pan 46, and at this time, the air conditioner 2 can be an integrated air conditioner.

[0084] Exemplarily, the flow guide structure is configured that the bottom wall of the second water pan 46 is gradually inclined downward toward the water collecting groove 440, so that the condensed water in the second water pan 46 can flow to the water collecting groove 440 under the action of gravity, so that the condensed water in the second water pan 46 can be timely treated, and the condensed water in the second water pan 46 is not easy to overflow, so as to reduce the risk of water soaking the components near the second water pan 46, thereby facilitating to improve the stability of the air conditioner 2 in operation.

[0085] As shown in Figures 1-3 In some embodiments, the refrigerant circulation system further includes an evaporator, a throttling device 64, a second refrigerant pipeline 30 and a third refrigerant pipeline 32, the first refrigerant pipeline 34 and the second refrigerant pipeline 30 are connected in series between the throttling device 64 and one end of the evaporator, for example, the first refrigerant pipeline 34 and the second refrigerant pipeline 30 are both used for transmitting refrigerant, the refrigerant passing through the throttling device 64 can first pass through the first refrigerant pipeline 34 and then pass through the second refrigerant pipeline 30 to the evaporator (as shown in Figure 3 ), or the refrigerant passing through the throttling device 64 can first pass through the second refrigerant pipeline 30 and then pass through the first refrigerant pipeline 34 to the evaporator, so as to complete the refrigerant transmission between the throttling device 64 and the evaporator, and the third refrigerant pipeline 32 is connected to the other end of the evaporator, for example, one end of the third refrigerant pipeline 32 is connected to the evaporator, and the other end is connected to the compressor 66, so as to complete the refrigerant transmission between the evaporator and the compressor 66. It can be understood that the first refrigerant pipeline 34 and the second refrigerant pipeline 30 can correspond to the inlet end of the evaporator, and the third refrigerant pipeline 32 corresponds to the outlet end of the evaporator, and when the air conditioner 2 is in operation, the first refrigerant pipeline 34, the second refrigerant pipeline 30 and the third refrigerant pipeline 32 will all produce condensed water.

[0086] As shown in Figures 1-3As shown, the air conditioner 2 further comprises a second pipe water receiving element 10, the second pipe water receiving element 10 has a second water receiving cavity 120 with a top opening and a second water outlet 126 in communication with the second water receiving cavity 120, a bottom wall of the second water receiving cavity 120 is formed with a first perforation 140 for one of the second refrigerant pipe 30 and the third refrigerant pipe 32 to pass through, for example, the second pipe water receiving element 10 is used to receive condensed water on the second refrigerant pipe 30, the second refrigerant pipe 30 can pass through the first perforation 140, or the second pipe water receiving element 10 is used to receive condensed water on the third refrigerant pipe 32, the third refrigerant pipe 32 can pass through the first perforation 140; and / or, the air conditioner 2 further comprises a third pipe water receiving element 20, the third pipe water receiving element 20 has a third water receiving cavity 220 with a top opening and a third water outlet 222 in communication with the third water receiving cavity 220, a bottom wall of the third water receiving cavity 220 is formed with a second perforation 240 for the other of the second refrigerant pipe 30 and the third refrigerant pipe 32 to pass through, for example, the third pipe water receiving element 20 is used to receive condensed water on the second refrigerant pipe 30, the second refrigerant pipe 30 can pass through the second perforation 240, or the third pipe water receiving element 20 is used to receive condensed water on the third refrigerant pipe 32, the third refrigerant pipe 32 can pass through the second perforation 240.

[0087] It can be understood that when the air conditioner 2 comprises the second pipe water receiving element 10 and the third pipe water receiving element 20, the second refrigerant pipe 30 passes through the first perforation 140 to the second pipe water receiving element 10, and the third refrigerant pipe 32 can pass through the second perforation 240 to the third pipe water receiving element 20; or the third refrigerant pipe 32 passes through the first perforation 140 to the second pipe water receiving element 10, and the second refrigerant pipe 30 can pass through the second perforation 240 to the third pipe water receiving element 20. Thus, the condensed water on the second refrigerant pipe 30 and the third refrigerant pipe 32 can be effectively received by the second pipe water receiving element 10 and the third pipe water receiving element 20 respectively, so that the condensed water is not easy to drip onto other components of the air conditioner 2, facilitating to improve the stability of the air conditioner 2 in operation.

[0088] As shown, Figures 1-3As shown, in some embodiments, the air conditioner 2 comprises a second pipeline water receiving element 10 and a third pipeline water receiving element 20. Among them, the second pipeline water receiving element 10 and the third pipeline water receiving element 20 are arranged in sequence along the horizontal direction, so that the second drain port 126 and the third drain port 222 are respectively opposite and communicated with the water receiving groove 440, then the condensed water in the third water receiving cavity 220 cannot flow to the second water receiving cavity 120 through the third drain port 222, and the condensed water in the second water receiving cavity 120 cannot flow to the third water receiving cavity 220 through the second drain port 126. For example, the second drain port 126 and the third drain port 222 are both located above the water receiving groove 440, or the first drain port 82 and the third drain port 222 are both extended downward into the water receiving groove 440, that is, the condensed water in the second water receiving cavity 120 can flow directly to the water receiving groove 440 through the second drain port 126, and the condensed water in the third water receiving cavity 220 can flow directly to the water receiving groove 440 through the third drain port 222, so that the second pipeline water receiving element 10 and the third pipeline water receiving element 20 are not easy to interfere with each other, and the stability of the air conditioner 2 in operation is improved.

[0089] Of course, part of the second pipeline water receiving element 10 can also be opposite to the third pipeline water receiving element 20 up and down. If the second pipeline water receiving element 10 is located on the upper side of the third pipeline water receiving element 20, the second drain port 126 and the third water receiving cavity 220 are staggered in the horizontal direction, so that the second drain port 126 and the third drain port 222 are respectively opposite and communicated with the water receiving groove 440; on the contrary, if the third pipeline water receiving element 20 is located on the upper side of the second pipeline water receiving element 10, the third drain port 222 and the second water receiving cavity 120 are staggered in the horizontal direction, so that the second drain port 126 and the third drain port 222 are respectively opposite and communicated with the water receiving groove 440.

[0090] Exemplarily, the second pipeline water receiving element 10 and the third pipeline water receiving element 20 are arranged in the horizontal direction, so that the second water receiving cavity 120 and the third water receiving cavity 220 are arranged in the horizontal direction, and the second drain port 126 and the third drain port 222 are also arranged in the horizontal direction, so that the second pipeline water receiving element 10 and the third pipeline water receiving element 20 are not easy to interfere with each other, and at the same time, the second pipeline water receiving element 10 and the third pipeline water receiving element 20 are not easy to interfere with each other during assembly, so as to improve the stability of the air conditioner 2 in operation.

[0091] In other embodiments of this application, the second water inlet 10 and the third water inlet 20 are arranged vertically in sequence, such that the second drain outlet 126 is connected to the water inlet 440 through the third water inlet cavity 220, or the third drain outlet 222 is connected to the water inlet 440 through the second water inlet cavity 120. For example, the second water inlet 10 is located above the third water inlet 20, and the condensate in the second water inlet cavity 120 can flow through the second drain outlet 126 to the third water inlet cavity 220, and then through the third drain outlet 222 to the water inlet 440; or, the third water inlet 20 is located above the second water inlet 10, and the condensate in the third water inlet cavity 220 can flow through the third drain outlet 222 to the second water inlet cavity 120, and then through the second drain outlet 126 to the water inlet 440. Therefore, the relative positions of the second water inlet 10 and the third water inlet 20 in the vertical direction are not limited in this application, so that the arrangement of the second water inlet 10 and the third water inlet 20 is more flexible.

[0092] As can be seen, the second water connection fitting 10 and the third water connection fitting 20 can be arranged sequentially in the horizontal direction or in the vertical direction, so that the installation positions of the second water connection fitting 10 and the third water connection fitting 20 are more flexible, which makes it easier to adapt to different installation environments and improves the practicality of the second water connection fitting 10 and the third water connection fitting 20.

[0093] like Figures 6-9 As shown, in some embodiments, the air conditioner 2 includes a second water inlet 10. The second water inlet 10 includes a first water inlet 12, a first mounting portion 14, and an elastic limiting portion 16. The first water inlet 12 has a second water inlet cavity 120 with a top opening. The first mounting portion 14 protrudes upward from the bottom wall 122 of the second water inlet cavity 120, and the second water inlet cavity 120 surrounds the first mounting portion 14. The first mounting portion 14 forms a first through hole 140. The elastic limiting portion 16 is disposed on the outer periphery of the first water inlet 12 and has a limiting hole 160. The hole wall 164 of the limiting hole 160 has a notch 162. The elastic limiting portion 16 is configured such that the width of the notch 162 (e.g., ...) is... Figure 7 d2) is smaller than the diameter of the limiting hole 160 (e.g. Figure 7 d1) so that another of the second refrigerant line 30 and the third refrigerant line 32 is adapted to be engaged in the limiting hole 160 through the notch 162. For example, the second refrigerant line 30 passes through the first through hole 140 and the third refrigerant line 32 is engaged in the limiting hole 160, or the third refrigerant line 32 passes through the first through hole 140 and the third refrigerant line 30 is engaged in the limiting hole 160.

[0094] Hereinafter, taking the second refrigerant pipeline 30 penetrating the first perforation 140 and the third refrigerant pipeline 32 clamping the limiting hole 160 as an example, the second pipeline water receiving element 10 is explained.

[0095] It can be seen that the second refrigerant pipeline 30 can penetrate the first perforation 140, since the second water receiving cavity 120 is arranged around the first mounting portion 14, it is convenient to form the hole wall of the first perforation 140 into a closed contour, in the direction perpendicular to the central axis of the first perforation 140, the second refrigerant pipeline 30 will not easily separate from the first mounting portion 14; moreover, the third refrigerant pipeline 32 clamps the limiting hole 160 through the gap 162, so that the third refrigerant pipeline 32 is not easily separated from the limiting hole 160 through the gap 162, and the elastic limiting portion 16 has a certain limiting effect on the third refrigerant pipeline 32, so that the second pipeline water receiving element 10 can be simultaneously matched with the second refrigerant pipeline 30 and the third refrigerant pipeline 32, realizing multi-point matching of the second pipeline water receiving element 10, so that the second pipeline water receiving element 10 is not easy to rotate relative to the second refrigerant pipeline 30 around the central axis of the first perforation 140, so that the setting position of the second pipeline water receiving element 10 is more stable, so that the effect of the second pipeline water receiving element 10 receiving condensed water is more stable; in short, the second refrigerant pipeline 30 penetrates the first perforation 140, and the third refrigerant pipeline 32 clamps the limiting hole 160, so as to limit the rotation of the second pipeline water receiving element 10 relative to the second refrigerant pipeline 30 around the central axis of the first perforation 140 by the cooperation of the elastic limiting portion 16 and the third refrigerant pipeline 32. It can be understood that by simultaneously matching the second pipeline water receiving element 10 with the second refrigerant pipeline 30 and the third refrigerant pipeline 32, the second pipeline water receiving element 10 is not easy to rotate relative to the second refrigerant pipeline 30 around the central axis of the first perforation 140, which reduces the limitation on the shape of the first perforation 140, for example, the shape of the first perforation 140 can be circular, polygonal, irregular, etc., and at the same time reduces the limitation on the shape of the second refrigerant pipeline 30, as long as the second refrigerant pipeline 30 can penetrate the first perforation 142. Thus, it is convenient to improve the applicability of the second pipeline water receiving element 10.

[0096] Exemplarily, if the second water receiving cavity 120 has a second drain port 126, the above arrangement can make the position of the second drain port 126 stable, that is, the drain position of the second pipeline water receiving element 10 is stable, so as to drain the water in the second water receiving cavity 120 to the desired position, which can improve the water leakage problem caused by the unstable drain position of the second pipeline water receiving element 10 due to the vibration of the air conditioner 2 during transportation and work; of course, the second water receiving cavity 120 can also not have the second drain port 126, for example, the condensed water on the second refrigerant pipeline 30 is relatively small.

[0097] The second water receiving cavity 120 is arranged around the first mounting portion 14, and the peripheral wall 124 of the second water receiving cavity 120 is arranged in a spaced manner with the first mounting portion 14, so that the condensed water generated on the peripheral wall of the second refrigerant pipeline 30 can be more comprehensively and effectively received by the second water receiving cavity 120, the condensed water is collected, the condensed water is conveniently treated in a centralized manner, and the condensed water is less likely to flow to other uncontrollable positions to affect the normal work of other lines and the like.

[0098] Exemplarily, the second refrigerant pipeline 30 can refer to a refrigerant pipeline for transmitting refrigerant. Since the refrigerant pipeline has a large temperature difference with the external environment during work, condensed water is easily generated on the surface of the refrigerant pipeline, and the second pipeline water receiving element 10 needs to be arranged to receive the condensed water, so that the condensed water is less likely to leak to other lines. Of course, the second refrigerant pipeline 30 can also be used to transmit other heat exchange media, such as water and the like.

[0099] In addition, the elastic limiting portion 16 is arranged on the outer peripheral side of the first water receiving portion 12, so that the elastic limiting portion 16 is less likely to block the top opening of the second water receiving cavity 120, and the third refrigerant pipeline 32 is also facilitated to avoid the top opening of the second water receiving cavity 120. In addition, the elastic limiting portion 16 is less likely to be disturbed by the first water receiving portion 12 when the third refrigerant pipeline 32 is assembled, so that a larger operation space is provided for the assembly of the third refrigerant pipeline 32 and the second pipeline water receiving element 10, and the assembly of the second pipeline water receiving element 10 is facilitated. The third refrigerant pipeline 32 is clamped in the limiting hole 160 through the gap 162, so that the second pipeline water receiving element 10 does not need to be installed by penetrating from one end of the third refrigerant pipeline 32, and the gap 162 can be directly aligned with the corresponding position of the third refrigerant pipeline 32 for assembly. The assembly method is relatively simple, and the assembly process of the second pipeline water receiving element 10 is facilitated. For example, the elastic limiting portion 16 can at least partially elastically deform, and a certain external force is applied to the elastic limiting portion 16 during assembly of the third refrigerant pipeline 32, so that the gap 162 can be deformed to a certain extent, and the third refrigerant pipeline 32 can be more conveniently clamped in the limiting hole 160.

[0100] The width of the gap 162 is smaller than the hole diameter of the limiting hole 160, so that the third refrigerant pipeline 32 is less likely to be pulled out after being clamped in the limiting hole 160. That is, the third refrigerant pipeline 32 is less likely to be pulled out from the gap 162 when the second pipeline water receiving element 10 is subjected to external vibration or impact, so that the second pipeline water receiving element 10 is self-fixed, and the stability of the second pipeline water receiving element 10 during operation is improved.

[0101] For example, the second refrigerant pipe 30 is first inserted through the first through hole 140 to complete the assembly of the second refrigerant pipe 30 and the second pipe water connector 10. Then, a certain external force is applied to the third refrigerant pipe 32 so that the third refrigerant pipe 32 can be locked into the limiting hole 160 through the notch 162. Once the third refrigerant pipe 32 is in the limiting hole 160, no further external force is applied to the third refrigerant pipe 32 so that it is not easy for the third refrigerant pipe 32 to come out through the notch 162. In this way, the second pipe water connector 10 is fitted into the second refrigerant pipe 30 and the third refrigerant pipe 32, which simplifies the assembly process of the second pipe water connector 10.

[0102] Furthermore, since the second water receiving cavity 120 is arranged around the first mounting part 14 and the elastic limiting part 16 is located on the outer periphery of the first water receiving part 12, the part of the second refrigerant pipe 30 that mates with the second pipe water receiving component 10 is referred to as the first part, and the part of the third refrigerant pipe 32 that mates with the second pipe water receiving component 10 is the second part. The first part and the second component are arranged separately, which helps to reduce the impact of the second refrigerant pipe 30 and the condensate on the second refrigerant pipe 30 on the third refrigerant pipe 32.

[0103] Optionally, the second refrigerant pipe 30 and the third refrigerant pipe 32 can be different pipes, for example, the second refrigerant pipe 30 and the third refrigerant pipe 32 can transmit different types of heat exchange media, and / or transmit heat exchange media at different temperatures respectively; of course, in other embodiments, the second refrigerant pipe 30 and the third refrigerant pipe 32 can also be connected by the same pipe, for example, the second refrigerant pipe 30 and the third refrigerant pipe 32 can also transmit the same type of heat exchange media with the same temperature.

[0104] like Figure 7 and Figure 8 As shown, in some embodiments, the central axis of the limiting hole 160 is parallel to the central axis of the first through hole 140, which simplifies the relative arrangement of the limiting hole 160 and the first through hole 140. Furthermore, at least a portion of the second refrigerant pipe 30 and at least a portion of the third refrigerant pipe 32 are also parallel to each other. The elastic limiting portion 16 and the third refrigerant pipe 32 are less likely to obstruct the top opening of the second water receiving cavity 120 and less likely to interfere with the first water receiving portion 12. And / or, at least a portion of the hole wall 164 of the limiting hole 160 participates in defining the peripheral wall 124 of the second water receiving cavity 120, so that a portion of the peripheral wall 124 of the second water receiving cavity 120 can participate in defining the limiting hole 160. Thus, the limiting hole 160 and the second water receiving cavity 120 have a structure that is at least partially shared, which helps reduce the amount of material used in manufacturing the second pipe water receiving component 10 and lowers the manufacturing cost of the second pipe water receiving component 10.

[0105] It can be understood that the hole wall 164 of the limiting hole 160 can partially participate in defining the peripheral wall 124 of the second water receiving cavity 120, or the whole of the hole wall 164 of the limiting hole 160 participates in defining the peripheral wall 124 of the second water receiving cavity 120, for example, the limiting hole 160 is defined by a part of the peripheral wall 124 of the second water receiving cavity 120, so as to further reduce the amount of material for manufacturing the second pipeline water receiving piece 10.

[0106] Exemplarily, the central axis of the limiting hole 160 is parallel to the central axis of the first perforation 140, and at least part of the hole wall 164 of the limiting hole 160 participates in defining the peripheral wall 124 of the second water receiving cavity 120. In combination with the arrangement that the second water receiving cavity 120 has a top opening, the peripheral wall 124 of the second water receiving cavity 120 can extend around a vertical axis, the peripheral wall 124 of the second water receiving cavity 120 can extend vertically upward or obliquely upward from the bottom wall of the second water receiving cavity 120, for example, the peripheral wall 124 can be cylindrical or conical, and then the central axis of the limiting hole 160 defined by part of the peripheral wall 124 is more likely to be parallel to the central axis of the first perforation 140. Of course, in other embodiments of the present application, the central axis of the limiting hole 160 can also form an acute angle with the central axis of the first perforation 140, the third refrigerant pipeline 32 cooperates with the limiting hole 160, and the second refrigerant pipeline 30 cooperates with the first perforation 140, so that the central axis of the part of the third refrigerant pipeline 32 cooperating with the limiting hole 160 and the central axis of the part of the second refrigerant pipeline 30 cooperating with the first perforation 140 form an acute angle, so that the third refrigerant pipeline 32 can limit the rotation of the second refrigerant pipeline 30 around the central axis of the first perforation 140, so as to make the arrangement position of the second refrigerant pipeline 30 more stable.

[0107] As shown in Figure 7 and Figure 8 In some embodiments, the elastic limiting part 16 includes a fixed part 166 and a deformed part 168 arranged in sequence along the circumference of the limiting hole 160, the fixed part 166 and the deformed part 168 define the limiting hole 160, one end of the fixed part 166 and one end of the deformed part 168 are spaced apart to define the gap 162, for example, one end of the fixed part 166 is connected with one end of the deformed part 168 to define the limiting hole 160, the other end of the fixed part 166 and the other end of the deformed part 168 are arranged in a spaced apart manner to define the gap 162, so that the staff can exert a certain external force on the third refrigerant pipeline 32 to make the deformed part 168 deform and change the width of the gap 162, and then the third refrigerant pipeline 32 is placed in the limiting hole 160 through the gap 162, thereby simplifying the assembly process of the third refrigerant pipeline 32 and the second pipeline water receiving piece 10. It can be understood that the deformed part 168 has good elastic deformation capacity relative to the fixed part 166.

[0108] The length of the deformation portion 168 is less than the length of the fixed portion 166 in the circumferential direction of the limiting hole 160. Thus, the elastic deformation ability of the elastic limiting portion 16 is considered, and the third refrigerant pipeline 32 is assembled conveniently. The longer fixed portion 166 makes the limiting hole 160 have sufficient structural strength, so that the limiting hole 160 is not easily deformed greatly. The fixed portion 166 can effectively support the third refrigerant pipeline 32, so that the third refrigerant pipeline 32 is not easily displaced greatly in the limiting hole 160. The assembly of the second pipeline water receiving element 10 and the third refrigerant pipeline 32 is more stable.

[0109] As shown in Figure 7 and Figure 8 , in some embodiments, the fixed portion 166 participates in defining the circumferential wall 124 of the second water receiving cavity 120, and the fixed portion 166 is recessed towards the second water receiving cavity 120. Thus, the fixed portion 166 can more fully utilize the space of the second water receiving cavity 120 to provide arrangement space for the third refrigerant pipeline 32. The structure of the second pipeline water receiving element 10 is more compact, facilitating the miniaturization design of the second pipeline water receiving element 10, and the structural stability of the second water receiving cavity 120 is not easily affected. The third refrigerant pipeline 32 is clamped in the limiting hole 160. Even if the third refrigerant pipeline 32 extrudes the circumferential wall 124 of the second water receiving cavity 120, the structural stability of the second water receiving cavity 120 is not easily affected.

[0110] Obviously, the fixed portion 166 is spaced apart from the first mounting portion 14, that is, there is a gap between the fixed portion 166 and the second refrigerant pipeline 30. Thus, the condensed water on the second refrigerant pipeline 30 is not easily flowed to the fixed portion 166, facilitating the stability of the second pipeline water receiving element 10.

[0111] As shown in Figure 7 and Figure 8 , in some embodiments, the length (such as L2 in Figure 7 ) of the second water receiving cavity 120 is greater than the width (such as L3 in Figure 7 ) of the second water receiving cavity 120. The fixed portion 166 is arranged on one side of the width of the second water receiving cavity 120. Thus, the fixed portion 166 can more fully utilize the space of the second water receiving cavity 120 in the width direction. The structure of the second pipeline water receiving element 10 is more compact, facilitating the miniaturization design of the second pipeline water receiving element 10. The length of one side edge of the second water receiving cavity 120 in the width direction is large, which does not easily limit the circumference and shape of the fixed portion 166. The arrangement space of the fixed portion 166 is large, which is beneficial to the second pipeline water receiving element 10 receiving more.

[0112] The fixed portion 166 has a first end 1660 and a second end 1662 oppositely arranged along the length direction of the second water receiving cavity 120, and the deformed portion 168 is cantilevered connected to the first end 1660, i.e. a gap 162 is defined between the free end of the deformed portion 168 and the second end 1660 of the fixed portion 166, and the deformed portion 168 extends from the first end 1660 to the second end 1662 in a direction away from the other side of the width direction of the second water receiving cavity 120. For example, the second water receiving cavity 120 has a first wall 50 and a second wall 51 oppositely arranged in the width direction, and the fixed portion 166 and the deformed portion 168 are both located on one side of the first wall 50, and the deformed portion 168 extends from the first end 1660 to the second end 1662 and is arranged in a direction away from the second wall 51, so as to facilitate increasing the size of the limiting hole 160 to a certain extent, so that when the third refrigerant pipeline 32 is located in the limiting hole 160, the third refrigerant pipeline 32 will not continuously press the deformed portion 168 outward of the limiting hole 160, thereby facilitating reducing the possibility of permanent damage or material fatigue of the deformed portion 168 caused by long-term pressure, and facilitating improving the service life of the second pipeline water receiving element 10.

[0113] As shown in Figure 7 and Figure 8 In some embodiments, the bottom wall 122 of the second water receiving cavity 120 is formed with a second drainage opening 126, and the bottom wall 122 of the second water receiving cavity 120 is further convexly provided with a water storage rib 128, which is arranged in a spaced manner with the first mounting portion 14 and separates the second drainage opening 126 from the first mounting portion 14. In this way, by convexly providing the water storage rib 128 on the bottom wall 122 of the second water receiving cavity 120 upward, the second water receiving cavity 120 has a certain water storage function. When the pipe segment of the second refrigerant pipeline 30 located above the second water receiving cavity 120 needs to be welded, a certain amount of water can be stored in the second water receiving cavity 120 in advance. After the high-temperature welding slag falls, it first contacts the water in the second water receiving cavity 120, and the water can quickly cool the welding slag, which can reduce the possibility of the welding slag melting the second pipeline water receiving element 10, so that the falling welding slag is not easy to damage the normal work of the second pipeline water receiving element 10. Moreover, the water storage rib 128 separates the second drainage opening 126 from the first mounting portion 14, so that the condensed water generated by the second refrigerant pipeline 30 is not easy to directly flow to the second drainage opening 126, but flows to the second drainage opening 126 after flowing over the water storage rib 128, so that the condensed water can flow gently in the second water receiving cavity 120, thereby facilitating improving the stability of the work of the second pipeline water receiving element 10.

[0114] For example, the water storage rib 128 extends in a closed ring shape and surrounds the second drainage opening 126, so that the water storage rib 128 separates the second drainage opening 126 from the first mounting portion 14, which is simple in structure and convenient to process.

[0115] AsFigure 7 and Figure 8 As shown in Figs. 1 and 2, in other embodiments of the present application, the water storage rib 128 extends in an open ring shape and both ends of the water storage rib 128 are connected to the peripheral wall 124 of the second water receiving cavity 120, and a part of the peripheral wall 124 of the second water receiving cavity 120 and the water storage rib 128 are arranged around the second drain port 126, which facilitates reducing the amount of material required for manufacturing the water storage rib 128, thereby reducing the manufacturing cost of the second pipe water receiving device 10.

[0116] It should be noted that the "ring shape" described herein is understood in a broad sense, i.e., not limited to a "circular ring shape", for example, it can also be a "polygonal ring" and the like; in addition, the "ring shape" includes an open ring shape (i.e., a non-closed ring shape, such as a C shape, a U shape, an Ω shape, etc.) and a closed ring shape.

[0117] It can be understood that the water storage rib 128 can be arranged at the edge of the second drain port 126 (as shown in Figs. 1 and 2), or alternatively, the water storage rib 128 can also be arranged spaced apart from the edge of the second drain port 126. Figure 7 and Figure 8 It can be understood that the water storage rib 128 can be arranged at the edge of the second drain port 126 (as shown in Figs. 1 and 2), or alternatively, the water storage rib 128 can also be arranged spaced apart from the edge of the second drain port 126.

[0118] As shown in Figs. 1 and 2, in other embodiments of the present application, the water storage rib 128 extends in an open ring shape and both ends of the water storage rib 128 are connected to the peripheral wall 124 of the second water receiving cavity 120, and a part of the peripheral wall 124 of the second water receiving cavity 120 and the water storage rib 128 are arranged around the second drain port 126, which facilitates reducing the amount of material required for manufacturing the water storage rib 128, thereby reducing the manufacturing cost of the second pipe water receiving device 10. Figure 10As shown, in some embodiments, the top of the water-storing rib 128 is higher than the highest point of the bottom wall 122 of the second water-receiving cavity 120, and the two are spaced apart by x in the vertical direction, where 0.5mm ≤ x ≤ 5mm. That is, the top of the water-storing rib 128 is located at a position x above the highest point of the bottom wall 122 of the second water-receiving cavity 120. When the vertical distance between the top of the water-storing rib 128 and the highest point of the bottom wall 122 of the second water-receiving cavity 120 is small (e.g., x < 0.5mm), the water storage capacity of the second water-receiving cavity 120 is weak. When the pipe section of the second refrigerant pipe 30 located above the second water-receiving cavity 120 needs to be welded, the high-temperature weld slag falls and first comes into contact with the water in the second water-receiving cavity 120. Due to the small amount of water stored, it may be difficult to achieve the desired water storage capacity. This results in a slower cooling rate of the welding slag. When the vertical distance between the top of the water storage rib 128 and the highest point of the bottom wall 122 of the second water receiving cavity 120 is large (e.g., x > 5 mm), the second water receiving cavity 120 has a good water storage capacity, allowing it to hold a large amount of water. However, a large amount of water cannot be drained in time, which may lead to the growth of bacteria, mold, and other microorganisms, affecting the cleanliness and hygiene of the second pipeline water receiving component 10. By setting the vertical distance between the top of the water storage rib 128 and the highest point of the bottom wall 122 of the second water receiving cavity 120 within the range of 0.5 mm to 5 mm, the second water receiving cavity 120 can have sufficient water storage capacity, and the water stored in the second water receiving cavity 120 can also be drained in time. For example, x can be 0.5mm, 0.8mm, 1.2mm, 1.4mm, 1.5mm, 1.9mm, 2.3mm, 2.7mm, 3.1mm, 3.6mm, 3.9mm, 4.1mm, 4.7mm, 5mm, etc.

[0119] The bottom wall 122 of the second water receiving cavity 120 is set horizontally, which reduces the processing difficulty and makes the processing of the second pipeline water receiving component 10 simpler, facilitating the large-scale production of the second pipeline water receiving component 10; or, the bottom wall 122 of the second water receiving cavity 120 is set inclined relative to the horizontal direction, and the position of the first mounting part 14 is higher than the position of the second drain outlet 126, that is, the position where the first mounting part 14 contacts the bottom wall 122 is higher than the position of the second drain outlet 126, so that the condensate generated by the second refrigerant pipeline 30 can flow to the second drain outlet 126 under the action of gravity, which facilitates the discharge of condensate in the second water receiving cavity 120, reduces the residence time of condensate in the water receiving cavity, and thus reduces the occurrence of potential problems such as scale and bacterial growth.

[0120] like Figures 7-10 As shown, in some embodiments, the central axis of the first perforation 140 (e.g.) Figure 10The bottom wall 122 of the second water receiving cavity 120 is inclined, and the included angle between the bottom wall 122 of the second water receiving cavity 120 and the horizontal plane is α, 1°≤α≤30°. By setting the included angle between the bottom wall 122 of the second water receiving cavity 120 and the horizontal plane in the range of 1° to 30°, the second water receiving cavity 120 has a certain slope, which facilitates the discharge of the condensed water in the second water receiving cavity 120, and the occupied space of the second pipeline water receiving element 10 in the vertical direction is not too large, which facilitates the adaptation to different use environments. For example, α is 1°, 4°, 9°, 11°, 14°, 17°, 20°, 21°, 24°, 27°, 30°, etc.

[0121] It can be understood that the discharge speed of the condensed water in the second water receiving cavity 120 is positively correlated with the included angle between the bottom wall 122 of the second water receiving cavity 120 and the horizontal plane. Therefore, when it is necessary to change the discharge of the condensed water in the second water receiving cavity 120, the included angle between the bottom wall 122 of the second water receiving cavity 120 and the horizontal plane can be changed correspondingly, so that the discharge speed of the condensed water is more appropriate.

[0122] As shown in FIG. 1, Figures 6-10 In some embodiments, at least part of the hole wall 164 of the limiting hole 160 participates in defining the peripheral wall 124 of the second water receiving cavity 120, and the above-mentioned at least part of the hole wall 164 of the limiting hole 160 is arranged between the water storage rib 128 and the first mounting portion 14. Therefore, the peripheral wall 124 of the second water receiving cavity 120 is arranged in a part of the hole wall 164 of the limiting hole 160 in a recessed manner, so that the limiting hole 160 is located between the water storage rib 128 and the first mounting portion 14. This is beneficial to reduce the size of the limiting portion 16 protruding outwardly from the first water receiving portion 12, so as to make the structure of the second pipeline water receiving element 10 more compact, facilitate the miniaturization design of the second pipeline water receiving element 10, and appropriately increase the distance between the water storage rib 128 and the first mounting portion 14, thereby facilitating the increase of the water storage capacity of the second water receiving cavity 120, so as to more quickly and timely reduce the temperature of the slag in the second water receiving cavity 120, and improve the use reliability of the second pipeline water receiving element 10.

[0123] As shown in FIG. 1, Figures 6-10As shown in the drawings, in some embodiments, the bottom wall 122 of the second water receiving cavity 120 is formed with a second water outlet 126, and the bottom wall 122 of the second water receiving cavity 120 is further provided with a water storage rib 128, which is spaced apart from the first mounting portion 14 and separates the second water outlet 126 from the first mounting portion 14. The water storage rib 128 extends in an open ring shape and is connected to the peripheral wall 124 of the second water receiving cavity 120 at both ends. A portion of the peripheral wall 124 of the second water receiving cavity 120 and the water storage rib 128 are arranged around the second water outlet 126. The elastic limiting portion 16 includes a fixing portion 166 and a deformation portion 168 arranged in sequence along the circumference of the limiting hole 160. The fixing portion 166 participates in defining the peripheral wall 124 of the second water receiving cavity 120 and is recessed towards the inside of the second water receiving cavity 120. At least a portion of the fixing portion 166 is arranged between the water storage rib 128 and the first mounting portion 14. As can be seen, one end of the water storage rib 128 can be connected to the fixing portion, so that the water storage rib 128 and the elastic limiting portion 16 are closer, so that the structure of the first water receiving member is more compact. At the same time, a portion of the peripheral wall 124 of the second water receiving cavity 120, a portion of the fixing portion 166, and the water storage rib 128 are arranged around the second water outlet 126, which facilitates reducing the amount of material required to manufacture the water storage rib 128, thereby reducing the manufacturing cost of the second pipeline water receiving member 10. Alternatively, the portion of the peripheral wall 122 of the second water receiving cavity 120 connected to the water storage rib 128 is spaced apart from the fixing portion 166, so that the water storage rib 128 and the elastic limiting portion 16 are farther apart, so that the water storage rib 128 does not easily affect the arrangement of the elastic limiting portion 16.

[0124] As shown in the drawings, Figure 10 and Figure 11 As shown in the drawings, in some embodiments, the upper end of the first mounting portion 14 has a first flow guide portion 142 adapted to be in interference fit with the second refrigerant pipeline 30. In the cross section of the first mounting portion 14, the outer peripheral contour length of the first flow guide portion 142 increases from top to bottom, for example, the first flow guide portion 142 is conical, the small end of the cone is located at the upper end of the first flow guide portion 142, and the large end of the cone is located at the lower end of the first flow guide portion 142. The cross section of the first mounting portion 14 is perpendicular to the central axis of the first through hole 140. In the longitudinal section of the first mounting portion 14, the included angle between the first flow guide portion 142 and the cross section of the first mounting portion 14 is β, and 30°≤β≤70°. The longitudinal section of the first mounting portion 14 passes through the central axis of the first through hole 140.

[0125] It can be seen that the first flow guide part 142 is in interference fit with the second refrigerant pipeline 30, so that the first flow guide part 142 and the second refrigerant pipeline 30 are more closely fitted, that is, the first flow guide part 142 can be partially deformed to fill the fitting gap between the two, so that the condensed water generated on the second refrigerant pipeline 30 is not easy to leak through the gap between the first flow guide part 142 and the second refrigerant pipeline 30, thereby improving the effect of the second pipeline water receiving part 10 receiving condensed water. For example, the pipe diameter (such as d3 in FIG. 13) of the second refrigerant pipeline 30 is 9 mm, and the inner diameter (such as d5 in FIG. 13) of the uppermost end of the first flow guide part 142 is 5 mm to 9 mm, so that the first flow guide part 142 and the second flow guide part 242 can be in interference fit, thereby facilitating the reduction of the fitting gap. Figure 5 Figure 10

[0126] In addition, the outer peripheral contour length of the first flow guide part 142 increases from top to bottom, and when the condensed water generated on the second refrigerant pipeline 30 flows to the first flow guide part 142 under the action of gravity, the outer peripheral contour of the first flow guide part 142 can guide the condensed water, so that the condensed water is not easy to accumulate on the fitting surface of the first flow guide part 142 and the second refrigerant pipeline 30, and the condensed water is not easy to penetrate into the gap between the first flow guide part 142 and the second refrigerant pipeline 30 due to surface tension. It can be understood that at least part of the first flow guide part 142 is in interference fit with the second refrigerant pipeline 30, for example, only the uppermost end of the first flow guide part 142 is in interference fit with the second refrigerant pipeline 30, and the other parts can be in gap fit, thereby facilitating the reduction of the resistance of the assembly of the second refrigerant pipeline 30 and the first flow guide part 142, so that the resistance of the assembly of the second pipeline water receiving part 10 and the second refrigerant pipeline 30 is not too large, thereby facilitating the assembly efficiency of the second pipeline water receiving part 10.

[0127] In the longitudinal section of the first mounting part 14, the included angle between the first flow guide part 142 and the cross section of the first mounting part 14 is β, and 30°≤β≤70°, so that the longitudinal section of the first flow guide part 142 is an inclined surface. When the inclination angle of the inclined surface is too small (for example, β<30°), the condensed water may be retained on the first flow guide part 142, increasing the risk of water accumulation. When the inclination angle of the inclined surface is too large (for example, β>70°), the axial dimension of the first flow guide part 142 may be large, so that the first flow guide part 142 is not convenient to process. By setting the inclination angle of the inclined surface in the above range, the risk of condensed water accumulation on the first flow guide part 142 is reduced, and the first flow guide part 142 is convenient to process.

[0128] ​​It can be understood that the cross-section included angle between the first flow guide portion 142 and the first mounting portion 14 can be a constant value, for example, the first flow guide portion 142 is conical, and the first mounting portion 14 is circular tube-shaped; or the cross-section included angle between the first flow guide portion 142 and the first mounting portion 14 can be changed, for example, the first mounting portion 14 is circular tube-shaped, and the first flow guide portion 142 is oblique conical, and the generatrix length of the first flow guide portion 142 gradually changes along with the extension of the conical shape, so that the cross-section included angle between the first flow guide portion 142 and the first mounting portion 14 also changes.

[0129] As shown in FIG. 1, in some embodiments, the second pipeline water receiving element 10 further comprises a binding portion 18, the binding portion 18 is downwardly protruding on the bottom wall 122 of the second water receiving cavity 120, and the binding portion 18 extends in a ring shape, the inner diameter (such as d4 in FIG. 1) of the binding portion 18 is greater than the hole diameter (such as d3 in FIG. 1) of the first perforation 140, so that the binding portion 18 is suitable for binding the heat preservation element wrapped outside the second refrigerant pipeline 30. Figures 6-10 Figure 10 As shown in FIG. 1, in some embodiments, the second pipeline water receiving element 10 further comprises a binding portion 18, the binding portion 18 is downwardly protruding on the bottom wall 122 of the second water receiving cavity 120, and the binding portion 18 extends in a ring shape, the inner diameter (such as d4 in FIG. 1) of the binding portion 18 is greater than the hole diameter (such as d3 in FIG. 1) of the first perforation 140, so that the binding portion 18 is suitable for binding the heat preservation element wrapped outside the second refrigerant pipeline 30. Figure 10

[0130] It can be seen that the binding portion 18 and the first mounting portion 14 are located on opposite sides of the second water receiving cavity 120, respectively, so that the binding portion 18 is not easy to interfere with the assembly of the first mounting portion 14 and the second refrigerant pipeline 30, and the above-mentioned arrangement makes the structure of the second pipeline water receiving element 10 more compact, which is convenient for reducing the occupied space of the second pipeline water receiving element 10, and is conducive to realizing the miniaturization design of the second pipeline water receiving element 10.

[0131] In addition, the inner diameter of the binding portion 18 is greater than the hole diameter of the first perforation 140, so that there is a certain gap in the radial direction between the binding portion 18 and the second refrigerant pipeline 30 passing through the first perforation 140, which is convenient for wrapping the heat preservation element outside the second refrigerant pipeline 30, so that the part of the second refrigerant pipeline 30 which cannot be received by the second pipeline water receiving element 10 (including the part of the second refrigerant pipeline 30 located on the lower side of the second pipeline water receiving element 10) can be wrapped with the heat preservation element, so that the second refrigerant pipeline 30 of the above-mentioned part is not easy to produce condensed water, thereby not easy to affect the normal work of other lines.

[0132] In addition, the inner diameter of the binding portion 18 is greater than the hole diameter of the first perforation 140, so that there is a certain gap in the radial direction between the binding portion 18 and the second refrigerant pipeline 30 passing through the first perforation 140, which is convenient for wrapping the heat preservation element outside the second refrigerant pipeline 30, so that the part of the second refrigerant pipeline 30 which cannot be received by the second pipeline water receiving element 10 (including the part of the second refrigerant pipeline 30 located on the lower side of the second pipeline water receiving element 10) can be wrapped with the heat preservation element, so that the second refrigerant pipeline 30 of the above-mentioned part is not easy to produce condensed water, thereby not easy to affect the normal work of other lines.

[0133] ​​It can be understood that the restraint part 18 can be an open ring or a closed ring, for example, the restraint part 18 is a "C" type, and the opening of the restraint part 18 faces the third refrigerant pipeline 32, so that there is more space between the restraint part 18 and the third refrigerant pipeline 32, so that the restraint part 18 and the third refrigerant pipeline 32 are not easy to interfere, and the applicability of the second pipeline water receiving piece 10 is improved.

[0134] In some embodiments, the second pipeline water receiving piece 10 is an integrally formed piece, for example, the first mounting part 14, the first water receiving part 12 and the elastic limiting part 16 are integrally formed, which can reduce the connection points between the first mounting part 14, the first water receiving part 12 and the elastic limiting part 16, improve the structural strength of the second pipeline water receiving piece 10, and the second water receiving cavity 120 defined by the first water receiving part 12 is not easy to have a water leakage risk, and the integrally formed piece is convenient for processing and manufacturing, which is beneficial to large-scale production of the second pipeline water receiving piece 10; and / or, the second pipeline water receiving piece 10 corresponds to the second refrigerant pipeline 30, the second refrigerant pipeline 30 and the third refrigerant pipeline 32 are welded and fixed, and the second refrigerant pipeline 30 and the third refrigerant pipeline are located above the second pipeline water receiving piece 10, the second pipeline water receiving piece 10 is a flame-retardant silica gel piece, for example, the second pipeline water receiving piece 10 is a flame-retardant silica gel (5VA), so that the second pipeline water receiving piece 10 has good high-temperature resistance, and when the second refrigerant pipeline 30 and the third refrigerant pipeline 32 need to be welded, by setting the second pipeline water receiving piece 10 as a flame-retardant silica gel piece, even if welding slag falls on the second pipeline water receiving piece 10, the second pipeline water receiving piece 10 is not easy to crack, deform and the like, which is convenient for improving the stability of the second pipeline water receiving piece 10.

[0135] As shown in FIG. 1, Figures 6-14 In some embodiments, the air conditioner 2 includes the second pipeline water receiving piece 10 and the third pipeline water receiving piece 20, the third pipeline water receiving piece 20 is arranged on the lower side of the second pipeline water receiving piece 10, and the third pipeline water receiving piece 20 includes the second water receiving part 22 and the second mounting part 24, the second water receiving part 22 has the third water receiving cavity 220 opposite to the second drain port 126, the second mounting part 24 is upwardly protruded on the bottom wall of the third water receiving cavity 220, and the third water receiving cavity 220 is arranged around the second mounting part 24, and the second mounting part 24 is formed with the second through hole 240 (for example, the second mounting part 24 is arranged opposite to the elastic limiting part 16, and the second refrigerant pipeline 30 or the third refrigerant pipeline 32 is arranged through the elastic limiting part 16 and the second through hole 240).

[0136] The upper end of the second mounting portion 24 has a second flow guide portion 242 adapted to interference fit with a corresponding refrigerant pipeline (for example, the second refrigerant pipeline 30 or the third refrigerant pipeline 32). In the cross section of the second mounting portion 24, the outer peripheral contour length of the second flow guide portion 242 increases from top to bottom, and the cross section of the second mounting portion 24 is perpendicular to the central axis of the second through hole 240. The third pipeline water connection piece 20 is an integral molding piece, for example, the second mounting portion 24 and the second water connection portion 22 are integrally molded, which facilitates reducing the connection points between the second mounting portion 24 and the second water connection portion 22, and is conducive to improving the structural strength of the third pipeline water connection piece 20. At the same time, the third water connection cavity 220 defined by the second water connection portion 22 is not prone to water leakage, and the integral molding piece is convenient for processing and manufacturing, which is conducive to large-scale production and manufacturing of the third pipeline water connection piece 20.

[0137] Hereinafter, the third refrigerant pipeline 32 is taken as an example of being arranged through the second through hole 240 to explain the third pipeline water connection piece 20 of the present application.

[0138] As can be seen, the third refrigerant pipeline 32 is arranged through the second through hole 240, so that the third refrigerant pipeline 32 can be matched with the third pipeline water connection piece 20 through the second mounting portion 24, and the third water connection cavity 220 is arranged around the second mounting portion 24, so that the condensed water generated on the third refrigerant pipeline 32 can be effectively collected by the third water connection cavity 220, and the condensed water is not prone to leak from the second mounting portion 24 to other pipelines. The third refrigerant pipeline 32 is interference fitted with the second flow guide portion 242, so that the third refrigerant pipeline 32 and the second flow guide portion 242 are matched more closely, and the condensed water is not prone to leak from the gap between the third refrigerant pipeline 32 and the second flow guide portion 242. In addition, the outer peripheral contour length of the second flow guide portion 242 increases from top to bottom, so that in the longitudinal cross section of the second mounting portion 24, the second flow guide portion 242 extends obliquely downward from top to bottom along the direction away from the central axis of the second through hole 240, so that the condensed water generated on the third refrigerant pipeline 32 can flow to the third water connection cavity 220 under the guidance of the second flow guide portion 242. The second mounting portion 24 is arranged opposite to the elastic limiting portion 16, so that the third refrigerant pipeline 32 does not need to be bent or the like, and the third refrigerant pipeline 32 can be matched with the second pipeline water connection piece 10 and the third pipeline water connection piece 20 at the same time.

[0139] In addition, the third pipeline water connection piece 20 is arranged on the lower side of the second pipeline water connection piece 10, and the second drain port 126 is arranged opposite to the third water connection cavity 220, so that the condensed water in the second water connection cavity 120 can flow to the third water connection cavity 220 through the second drain port 126, so that the third water connection cavity 220 can collect the condensed water in the second water connection cavity 120, so that the condensed water can be collected in the second water connection cavity 120, which is convenient for subsequent centralized treatment of the condensed water.

[0140] It is understandable that both the second refrigerant line 30 and the third refrigerant line 32 can refer to refrigerant lines used to transfer refrigerant.

[0141] In some embodiments, the air conditioner 2 includes a refrigerant circulation system, which includes a compressor 66, a reversing device, an indoor heat exchanger, a condenser 68, a throttling device 64, a second refrigerant pipe 30, and a third refrigerant pipe 32. The second refrigerant pipe 30 passes through a first through-hole 140, and the third refrigerant pipe 32 is secured to a limiting hole 160 through a notch 162. The second refrigerant pipe 30 can be a refrigerant pipe in the refrigerant circulation system. Low-temperature refrigerant flows within the second refrigerant pipe 30, and condensation easily forms on the outer peripheral wall of the second refrigerant pipe 30. The second pipe water inlet 10 can collect the condensation on the second refrigerant pipe 30.

[0142] It can be seen that the second pipe water inlet 10 works in conjunction with both the second refrigerant pipe 30 and the third refrigerant pipe 32 to make the installation position of the second pipe water inlet 10 more stable, so that the effect of the second pipe water inlet 10 in receiving condensate water is more stable, and the condensate water is less likely to leak to other lines of the air conditioner 2, which helps to improve the stability of the operation of the air conditioner 2.

[0143] It is understood that the type of air conditioner 2 in this application embodiment is not limited. It can be a vehicle air conditioner, an integrated air conditioner, or a split air conditioner. An integrated air conditioner can include a window air conditioner or a portable air conditioner, etc., and a split air conditioner can include a wall-mounted air conditioner or a floor-standing air conditioner, etc.

[0144] like Figure 13 , Figure 15 and Figure 17 As shown, in some embodiments, a second refrigerant line 30 is connected between the return port of the compressor 66 and one end of the indoor heat exchanger (e.g., the evaporator described above), and a third refrigerant line 32 is connected between the throttling device 64 and the other end of the indoor heat exchanger (e.g., the evaporator).

[0145] As can be seen, the second refrigerant pipe 30 and the third refrigerant pipe 32 are connected to the two ends of the indoor heat exchanger, respectively. Therefore, the temperature difference between the refrigerant transported in the second refrigerant pipe 30 and the external environment is relatively large, making it easy for condensation to form on the second refrigerant pipe 30 and the third refrigerant pipe 32. By installing the second pipe water inlet 10 and the third pipe water inlet 20, the condensation can be effectively collected by the second pipe water inlet 10 and the third pipe water inlet 20; or, the second pipe water inlet 10 can be fitted onto the second refrigerant pipe 30 to effectively collect the condensation generated by the second refrigerant pipe 30. The third refrigerant pipe 32 is covered with insulation cotton to prevent condensation from forming on the third refrigerant pipe 32, thus reducing the possibility of condensation leaking into other lines.

[0146] For example, when the air conditioner 2 operates in the cooling mode, the compressor first compresses the refrigerant into high-temperature and high-pressure refrigerant, which is then transmitted to the outdoor heat exchanger through the discharge port of the compressor. The heat in the refrigerant is released to the environment through the outdoor heat exchanger, so that at least part of the refrigerant is condensed from the gas state to the liquid state. Subsequently, the liquid refrigerant flows through the throttling device 64, and the refrigerant after temperature reduction by the throttling device 64 enters the indoor heat exchanger through the third refrigerant pipeline 32. The refrigerant of the indoor heat exchanger absorbs the indoor heat to realize the refrigeration of the air conditioner 2. The refrigerant after heat exchange flows to the suction port of the compressor through the second refrigerant pipeline 30, and the compressor again compresses the refrigerant to start the next refrigeration cycle of the refrigerant.

[0147] As shown in FIG. 1, in some embodiments, the third water receiving cavity 220 is formed with a third water outlet 222, and the edge of the third water outlet 222 has a downwardly extending water drainage section 224. One of the third water drainage section 224 and the second water receiving part 22 is limitedly matched with the groove wall of the water receiving groove 440 to limit the rotation of the third pipeline water receiving part 20 relative to the third refrigerant pipeline 32. Figures 12-16

[0148] It can be seen that the second pipeline water receiving part 10 can be used to receive the condensed water generated on the second refrigerant pipeline 30, and the third pipeline water receiving part 20 can be used to receive the condensed water generated on the third refrigerant pipeline 32. The condensed water in the second water receiving cavity 120 can flow to the third water receiving cavity 220 through the second water outlet 126, so that the condensed water generated on the second refrigerant pipeline 30 and the third refrigerant pipeline 32 can be gathered in the third water receiving cavity 220, and then flow to the water drainage section 224 through the third water outlet 222. The water drainage section 224 then guides the condensed water into the water receiving groove 440, and the water receiving groove 440 then guides the condensed water to other positions such as the outside of the air conditioner 2. Thus, the treatment of the condensed water generated on the second refrigerant pipeline 30 and the third refrigerant pipeline 32 is completed, so that the condensed water in the second pipeline water receiving part 10 and the third pipeline water receiving part 20 is not easy to leak to other lines, thereby facilitating the improvement of the stability of the operation of the air conditioner 2.

[0149] In addition, one of the water drainage section 224 and the second water receiving part 22 is limitedly matched with the groove wall of the water receiving groove 440 to make the setting position of the third pipeline water receiving part 20 more stable and not easy to rotate, so that the second water outlet 126 and the third pipeline water receiving part 20 are not easy to be misaligned, and the water drainage section 224 and the water receiving groove 440 are not easy to be misaligned, so that the discharge path of the condensed water is more clear, and the problem of leakage of the condensed water is not easy to occur, thereby further improving the stability of the operation of the air conditioner 2.

[0150] ​In the above-mentioned scheme, optionally, the upper end of the second mounting part 24 has a second guide part 242, the second guide part 242 is adapted to be interference fit with the third refrigerant pipe 32, on the cross-section of the second mounting part 24, the circumference of the outer perimeter of the second guide part 242 increases from top to bottom, the cross-section of the second mounting part 24 is perpendicular to the central axis of the second perforation 240; and / or, the third pipe water receiving part 20 is an integrally formed part.

[0151] like Figures 13-16 As shown, in some embodiments, a first stop portion 53 is also formed on the wall of the water receiving tank 440. The first stop portion 53 is disposed on one side of the third pipeline water receiving component 20 in the circumferential direction of the second through hole 240, and the first stop portion 53 is adapted to cooperate with the second water receiving portion 22 to limit the rotation of the third pipeline water receiving component 20 toward the first stop portion 53, so as to make the setting position of the third pipeline water receiving component 20 more stable; and / or, a second stop portion 54 is also formed on the wall of the water receiving tank 440. The second stop portion 54 is disposed on the other side of the third pipeline water receiving component 20 in the circumferential direction of the second through hole 240, and the second stop portion 54 is adapted to cooperate with the drainage section 224 to limit the rotation of the third pipeline water receiving component 20 toward the second stop portion 54, so as to make the setting position of the third pipeline water receiving component 20 more stable.

[0152] As can be seen, by providing a first stop 53 and a second stop 54, the third pipe water receiving component 20 is located between the first stop 53 and the second stop 54, so that the first stop 53 and the second stop 54 can work together to restrict the rotation of the third pipe water receiving component 20 relative to the third refrigerant pipe 32, making the setting position of the third pipe water receiving component 20 more stable. As a result, the effect of the third pipe water receiving component 20 in receiving and transmitting condensate is more stable, effectively reducing problems such as condensate leakage.

[0153] In some embodiments, the air conditioner 2 is a kitchen air conditioner. Exemplarily, the kitchen air conditioner is an integrated air conditioning unit with a relatively compact structure and complex wiring. The pipes usually need to be welded together so that the welded parts of the pipes cannot be covered with closed insulation cotton. By setting a second pipe water inlet 10 at the bottom of the above-mentioned pipes, the possibility of condensate generated in the pipes affecting other lines is reduced, thereby improving the stability of the kitchen air conditioner's operation.
