Because the number of internal components of the whole heat pump is large, the layout is complex, and the space is limited, if the waterway component installation is simple, the operation is simple, the installation is firm, the production efficiency of the product can be greatly improved.

[0003] In the related art, the connection of the waterway component of the whole heat pump and the water pipeline usually adopts conventional nut thread connection, and the sealing effect is achieved by extruding the middle gasket through the hex nut.

[0089] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and refrigeration or heating of indoor space.

[0090] The low-temperature and low-pressure refrigerant enters the compressor, which compresses the refrigerant gas into a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0091] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant formed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with the material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0118] The second limiting part 913 is protrudingly arranged on the outer wall of the first plug-in part 910 and can be a complete annular protrusion or a plurality of separate protrusions arranged at intervals in the circumferential direction.

[0119] As shown in Figure 13 , the second plug-in part 920 further comprises a third limiting part 922 and a fourth limiting part 923.

[0120] The third limiting part 922 is formed on the inner wall of the second plug-in part 921 and is used to stop and limit the first plug-in part 910. Specifically, when the first plug-in part 910 is inserted into the second plug-in part 921 to abut against the third limiting part 922 at the end face, the first plug-in part 910 is plugged into the second plug-in part 920, and the water module pipeline 600 is plugged into the water pump 700.

[0121] The fourth limiting part 923 is protrudingly arranged on the outer wall of the second plug-in part 920 and can be a complete annular protrusion or a plurality of separate protrusions arranged at intervals in the circumferential direction.

[0122] When the water module pipeline 600 is plugged into the water pump 700, the end face of the second limiting part 913 and the end face of the fourth limiting part 923 also abut against each other, further stopping and limiting the plugging of the water module pipeline 600 and the water pump 700, as shown in Figure 9 and Figure 13 .

[0123] Therefore, through the above structure, each component of the first quick plug-in connection structure 900 can be accurately and quickly plugged into place, further improving the installation efficiency.

[0124] As for the locking part 940, in some embodiments of the present application, it is a clamp, i.e. a resilient clamp with one end closed and the other end having an opening, as shown in Figure 9 . It is convenient to disassemble and assemble. Specifically, when locking, force is applied to the closed end of the locking part 940 to make the open end expand and insert into the plug-in part of the first plug-in part 910 and the second plug-in part 920, and the first plug-in part 910 and the second plug-in part 920 are clamped under the elastic force.

[0125] The locking member 940 has a through portion 941 for avoiding the second limiting portion 913 and the fourth limiting portion 923. That is, in the clamped state, a portion of the second limiting portion 913 and the fourth limiting portion 923 is embedded in the through portion 941 of the locking member 940, so that the second limiting portion 913 and the fourth limiting portion 923 can restrict the locking member 940 from sliding down and disengaging from the first connector 910 and the second connector 920, thus ensuring reliable locking.

[0126] Of course, the locking element 940 can also adopt other structures, such as other forms of clamps, stainless steel cable ties, etc., and no specific restrictions are imposed here.

[0127] like Figures 6 to 8 , Figures 10 to 12 As shown, in some embodiments of this application, a flow meter 1100 is connected to the water module pipeline 600 to more accurately identify the water flow rate. The flow meter 1100 is connected to the water module pipeline 600 via a second quick-connect connection structure 1200, that is, the inlet and outlet of the flow meter 1100 are connected to the corresponding connectors of the water module pipeline 600 via the second quick-connect connection structure 1200, realizing quick and convenient installation and removal of the flow meter 1100. The flow meter 1100 is connected in series with the water pump 700 on the water module pipeline 600.

[0128] The second quick-connect structure 1200 has the same structure as the first quick-connect structure 900, that is, the second quick-connect structure 1200 also includes a first connector 910, a second connector 920, a seal 930 and a locking member 940.

[0129] In some embodiments of this application, unlike the first quick-connect structure 900, the first connector 910 of the second quick-connect structure 1200 is provided on the corresponding connector end of the water module pipeline 600, and the second connector 920 is provided on the inlet and outlet of the flow meter 1100; or, the first connector 910 of the second quick-connect structure 1200 is provided on the inlet and outlet of the flow meter 1100, and the second connector 920 is provided on the corresponding connector end of the water module pipeline 600.

[0130] In some embodiments of this application, such as Figures 5 to 7 As shown, the plate heat exchanger 810 is installed vertically, and the first port 811 of the water flow path of the plate heat exchanger 810 is located below its second port 812.

[0131] like Figures 5 to 9As shown, the water module pipeline 600 includes a first water module pipeline 610 and a second water module pipeline 620. The first end I of the first water module pipe 610 is connected to the first port 811 of the water flow path of the plate heat exchanger 810, and the second end II of the first water module pipe 610 is connected to the first through hole 150 on the housing 100 for external water connection; the position of the second end II of the first water module pipe 610 is lower than the first port 811 of the water flow path of the plate heat exchanger 810; the first end I of the second water module pipe 620 is connected to the second port 812 of the water flow path of the plate heat exchanger 810, and the second end II of the second water module pipe 620 is connected to the second through hole 160 on the housing 100 for external water connection; thus, one of the first water module pipe 610 and the second water module pipe 620 serves as the inlet water pipe, and the other serves as the outlet water pipe. External water enters the water flow path of the plate heat exchanger 810 through the inlet water pipe, exchanges heat with the refrigerant, and then flows out through the outlet water pipe.

[0132] The first water module pipeline 610 includes a vertical section 611, on which the flow meter 1100 is connected and installed in the forward direction, meaning the water flow direction is consistent with the required direction of the flow meter 1100. This ensures the required straight section length of the flow meter 1100's inlet and outlet, thus guaranteeing its accuracy. Furthermore, the vertical section 611 allows the first water module pipeline 610 to be installed as vertically as possible, maximizing the utilization of the heat pump housing 100's height and reducing the overall footprint.

[0133] like Figure 6 and Figure 7 As shown, the top end c of the vertical section 611 is higher than the first port 811 of the plate heat exchanger 810. That is, in the vertical height direction, the top end c of the vertical section 611 is located above the first port 811 of the plate heat exchanger 810, so as to further make the water module pipeline 600 more compact and reduce the space occupation.

[0134] A bypass pipe 630 is provided on the first water module pipe 610. Both ends of the bypass pipe 630 are connected to the first water module pipe 610, and one end of the bypass pipe 630 is connected to the connection point of the first water module pipe 610, i.e. Figure 8 Point a in the diagram is the connection point between the other end of the bypass pipe 630 and the first end I of the first water module pipe 610, which is also the first port 811 of the water flow path of the plate heat exchanger 810. Figure 8 Point b in the diagram is located below the first end I of the first pipeline 610 of the water module, which is also below the first port 811 of the water flow path of the plate heat exchanger 810.

[0135] If the plate heat exchanger 810 has water storage, the water storage is at the bottom of the plate heat exchanger 810. Since the water module first pipeline 610 is provided with a vertical section 611, and the top end c of the vertical section 611 is located higher than the first port 811 of the plate heat exchanger 810, the water storage in the plate heat exchanger 810 is difficult to be discharged through the water module first pipeline 610.

[0136] In some embodiments of the present application, a bypass pipeline 630 is arranged on the water module first pipeline 610. One end of the bypass pipeline 630 is connected to the water module first pipeline 610 at the connection point a, which is close to the first port 811 of the water flow path of the plate heat exchanger 810. The other end of the bypass pipeline 630 is connected to the water module first pipeline 610 at the connection point b, which is located lower than the first port 811 of the water flow path of the plate heat exchanger 810, and the second end II of the water module first pipeline 610 is also located lower than the first port 811 of the water flow path of the plate heat exchanger 810. Therefore, if the plate heat exchanger 810 has water storage, and there is a need to drain water in winter, the second end II of the water module first pipeline 610 can be opened, and the water storage in the plate heat exchanger 810 can be introduced into the second end II of the water module first pipeline 610 through the bypass pipeline 630, and then discharged through the second end II of the water module first pipeline 610, so as to prevent the plate heat exchanger from being frozen.

[0137] In some embodiments of the present application, the height position of the pipeline section between the connection point b and the second end II of the water module first pipeline 610 (for the convenience of description, this part of the pipeline section can be referred to as the low-position pipeline section 612) is lower than the height position of the connection point b, so as to improve the smoothness of water storage and drainage. When draining water in winter, the second end II of the water module first pipeline 610 is opened, and the water storage in the plate heat exchanger 810 is introduced into the low-position pipeline section 612 of the water module first pipeline 610 through the bypass pipeline 630, and then discharged through the second end II of the water module first pipeline 610.

[0138] In some embodiments of the present application, the first port 811 of the water flow path of the plate heat exchanger 810 is the water inlet, and the second port 812 is the water outlet. Correspondingly, the water module first pipeline 610 is the water inlet pipeline, and the water module second pipeline 620 is the water outlet pipeline, so that the flow meter 1100 is arranged on the vertical section 611 of the water inlet pipeline, and the measurement accuracy of the flow meter 1100 is higher.

[0139] In some embodiments of the present application, the water pump 700 is also arranged on the vertical section 611 of the water module first pipeline 610.

[0140] In some embodiments of the present application, a micro-bubble exhaust valve 1300 is further connected to the water module pipeline 600. If the plate heat exchanger 810 is broken, the micro-bubble exhaust valve 1300 can quickly discharge the refrigerant dissolved in the water, so as to prevent the refrigerant from entering the room.

[0141] In the description of the above-mentioned embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0142] The above merely describes the specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
