[0060] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0061] 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 to cool or heat the indoor space.

[0062] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas 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 the heat is released to the surrounding environment through the condensation process.

[0063] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0064] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0065] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0066] refer to Figure 1 , Figure 2 The present application provides an air conditioner, which includes an outer shell 100, the outer shell 100 includes a top wall 110, a bottom wall 120 and side walls, and the top wall 110, the bottom wall 120 and the side walls are arranged to form an installation cavity for installing working parts.

[0067] The fan coil unit 200 is arranged in the installation inner cavity, and the fan coil unit 200 is connected with a liquid inlet pipe group, a liquid outlet pipe group and a connecting pipe group.

[0068] The liquid inlet pipe group is used to input heat exchange medium into the heat exchange tube group, and the liquid outlet pipe group is used to output the heat exchange medium in the heat exchange tube group.

[0069] Combination Figure 4 The liquid inlet pipe group is connected to the liquid inlet pipeline 210 through the first connector 230, and the liquid outlet pipe group is connected to the liquid outlet pipeline 220 through the second connector 240.

[0070] The liquid inlet pipeline 210 is located above the liquid outlet pipeline 220 .

[0071] The heat exchange tube group includes a plurality of U-shaped tubes, and the U-shaped tubes include a liquid inlet and a liquid outlet.

[0072] The liquid inlet pipe group is connected with the liquid inlet, and the liquid outlet pipe group is connected with the liquid outlet. The position of the liquid inlet on each U-shaped tube is higher than the liquid outlet.

[0073] The connection position between the first connector 230 and the liquid inlet pipeline 210 is located outside the outer shell 100 , and the connection position between the second connector 240 and the liquid outlet pipeline 220 is also located outside the outer shell 100 .

[0074] That is, the first connector 230 passes through the side wall of the outer shell 100 , and one end thereof extending into the outer shell 100 is connected to the liquid inlet pipe set, and the other end extending outside the outer shell 100 is connected to the liquid inlet pipeline 210 .

[0075] The second connector 240 passes through the side wall of the outer shell 100 , and one end thereof extending into the outer shell 100 is connected to the liquid outlet tube set, and the other end thereof extending outside the outer shell 100 is connected to the liquid outlet pipeline 220 .

[0076] An internal water tray 300 is disposed below the fan coil unit 200 , and the bottom of the internal water tray 300 is fixed to the bottom wall 120 of the outer shell 100 .

[0077] refer to Figure 3 A water collecting tank is formed in the internal water tray 300 for collecting condensed water dripping from the surface of the fan coil unit 200 .

[0078] The water collecting tank is externally connected to a drain pipe 310 for collecting condensed water etc. formed during the operation of the fan coil unit 200 and then discharging the condensed water through the drain pipe 310 .

[0079] Since the liquid outlet pipeline 220 and the liquid inlet pipeline 210 are located outside the outer shell 100, during actual operation, condensed water is formed outside the liquid outlet pipeline 220 and the liquid inlet pipeline 210 due to the temperature difference between the internal heat exchange medium and the external environment.

[0080] Alternatively, although the connection positions between the liquid inlet pipe 210 and the first connector 230, and the liquid outlet pipe 220 and the second connector 240 are sealed with materials such as raw tape, dripping or leakage may still occur. Condensed water and leaked water may soak the user's ceiling or other furniture items, causing losses to the user.

[0081] In order to prevent water leakage or condensation from damaging the ceiling and furniture, the present application designs an external water connection piece 400 , which is detachably connected to the outside of the outer shell 100 and is located below the liquid inlet pipe 210 and the liquid outlet pipe 220 .

[0082] refer to Figure 5 , Figure 6 Specifically, the external water receiving part 400 includes an upper water receiving portion 410 , a lower water receiving portion 420 and a transition portion 430 , and the transition portion 430 is located between the upper water receiving portion 410 and the lower water receiving portion 420 .

[0083] The upper water receiving portion 410 is located below the liquid inlet pipeline 210 , and the lower water receiving portion 420 is located below the liquid outlet pipeline 220 .

[0084] A water guide pipe 441 extending to the upper side of the inner water receiving tray 300 is formed at one end of the lower water receiving portion 420 close to the outer shell 100 , and is used to transport the accumulated water in the lower water receiving portion 420 to the inner water receiving tray 300 .

[0085] Specifically, an end wall 440 bent upward is formed at one end of the lower water receiving portion 420 close to the outer shell 100 , a water hole is opened on the end, and a water pipe 441 is connected to the water hole for discharging water in the lower water receiving portion 420 .

[0086] The water pipe 441 can be inserted into the water hole, or the water pipe 441 can also be welded to the outside of the lower water receiving part 420. In addition, when the external water receiving part 400 is made of plastic material, the water pipe 441 can also be formed integrally with the lower water receiving part 420.

[0087] In some embodiments of the present application, the upper water receiving portion 410 is formed with a water receiving surface inclined toward the lower water receiving portion 420 , and the lower water receiving portion 420 is formed with a drainage surface inclined toward the outer shell 100 .

[0088] That is, the height of the water receiving surface gradually decreases along the direction close to the lower water receiving portion 420 , so as to guide the water drops dripping from the liquid inlet pipeline 210 to the lower water receiving portion 420 .

[0089] The drainage surface on the lower water receiving portion 420 gradually decreases along the direction approaching the outer shell 100 to discharge the water on the lower water receiving portion 420 in the direction of the water tank outer shell 100 until it is input into the inner water receiving tray 300 through the water guide pipe 441.

[0090] In some embodiments of the present application, the water pipe 441 is located at the lowest end of the drainage surface, that is, the water hole on the end wall 440 is connected to the lowest position of the drainage surface so that all the accumulated water on the lower water receiving part 420 can be discharged to the water pipe 441.

[0091] In some embodiments of the present application, a water-retaining edge 450 is formed on the peripheral side of the external water receiving member 400. The water-retaining edge 450 is arranged on the outer periphery of the external water receiving member 400 to form a bend extending upward on the external water receiving member 400 to prevent the accumulated water on the external water receiving member 400 from flowing out.

[0092] The water-retaining outer edge 450 includes a main water-retaining outer edge 451 perpendicular to the side wall of the outer shell 100 and an auxiliary water-retaining outer edge 450 arranged parallel to the side wall of the outer shell 100 .

[0093] Specifically, a main water retaining edge 451 is formed on both the upper water receiving portion 410 and the lower water receiving portion 420 , and the height of the main water retaining edge 451 gradually increases in a direction approaching the outer shell 100 to prevent accumulated water from flowing out from the outside during the flow process.

[0094] In some embodiments of the present application, a connection portion 460 is formed on the external water receiving member 400 for fixed connection with the outer shell 100 . The connection portion 460 is formed at one end of the main water retaining outer edge 451 and is bent outward.

[0095] The connecting portion 460 is detachably connected to the outer shell 100 via a fastener. A connecting hole is formed on the connecting portion 460 , and a fastening hole is formed at a corresponding position of the outer shell 100 . The fastener passes through the connecting hole and the fastening hole to fix the connecting portion 460 to the outer shell 100 .

[0096] In some embodiments of the present application, the upper water receiving portion 410, the lower water receiving portion 420, the transition portion 430 and the water retaining outer edge 450 are an integrally formed structure.

[0097] In some embodiments of the present application, the material of the external water receiving part 400 is plastic, and the upper water receiving part 410, the lower water receiving part 420, the transition part 430 and the water retaining outer edge 450 are integrally formed by injection molding, which facilitates processing and reduces assembly.

[0098] In other embodiments, the material of the external water receiving member 400 is sheet metal, and the upper water receiving portion 410, the lower water receiving portion 420, the transition portion 430 and the water retaining outer edge 450 are made by sheet metal forming.

[0099] In some embodiments of the present application, a heat-insulating layer is disposed on the outer side of the external water receiving member 400 to prevent condensation from forming on the external water receiving member 400 .

[0100] refer to Figure 7-Figure 11 In some embodiments of the present application, the fan coil unit 200 is tilted above the inner water tray 300 through the support assembly 500 .

[0101] Specifically, the heat exchange surface of the fan coil unit 200 is tilted above the internal water tray 300. Compared with the vertical placement of the heat exchange surface of the fan coil unit 200, the tilted placement can increase the heat exchange area of ​​the fan coil unit 200.

[0102] In some embodiments of the present application, the support assembly 500 includes a first support member 510 and a second support member 520 respectively disposed at both ends of the fan coil unit 200 , and the first support member 510 and the second support member 520 are connected to the inner water tray 300 and the outer shell 100 .

[0103] In some embodiments of the present application, inclined support surfaces are respectively formed on the first support member 510 and the second support member 520. Specifically, an inclined first support surface 513 is formed on the first support member 510, and an inclined second support surface 523 is formed on the second support member 520, for supporting the fan coil unit 200.

[0104] Specifically, the shapes of the first support member 510 and the second support member 520 may be the same to provide support for both ends of the fan coil unit 200, or the first support member 510 and the second support member 520 may be designed to be different.

[0105] Next, an implementation method is proposed for the specific structure of the first support member 510 and the second support member 520:

[0106] refer to Figure 8 , Fig. 9 The first support member 510 is a sheet metal member, and a first support bottom surface 511 is formed at the bottom of the first support member 510. The first support bottom surface 511 is a flange formed at the bottom of the first support member 510, which is used to contact the bottom of the water receiving tray, thereby increasing the support area of ​​the first support member 510 and improving the stability of the connection.

[0107] A first fixing end surface 512 is formed on one side of the first support member 510 close to the side wall of the outer shell 100 . A fixing hole is formed on the first fixing end surface 512 for detachably connecting the first support member 510 to the outer shell 100 through a fastener.

[0108] A first avoidance groove 514 is further formed at the lower end of the first fixed end surface 512 . In the installed state, the first avoidance groove 514 matches the outer edge of the inner water tray 300 to avoid interference with the inner water tray 300 .

[0109] A supporting upper portion 515 is further disposed above the first supporting member 510 , and a supporting inclined surface adapted to the fan coil unit 200 is formed on the lower side of the supporting upper portion 515 .

[0110] In the installed state, the rear side of the fan coil unit 200 is supported on the first support surface 513, and the top end of the fan coil unit 200 is in contact with and connected to the support inclined surface.

[0111] refer to Fig.10 , Fig.11 The second support member 520 is a sheet metal member, and a second support bottom surface 521 is formed at the bottom of the second support member 520. The second support bottom surface 521 is a flange formed at the bottom of the second support member 520, which is used to contact the bottom of the water receiving tray, thereby increasing the support area of ​​the second support member 520 and improving the stability of the connection.

[0112] A second fixing end surface 522 is formed on one side of the second support member 520 close to the side wall of the outer shell 100 . A fixing hole is formed on the second fixing end surface 522 for detachably connecting the second support member 520 to the outer shell 100 through a fastener.

[0113] A second avoidance groove 524 is further formed at the lower end of the second fixed end surface 522 . In the installed state, the second avoidance groove 524 matches the outer edge of the inner water tray 300 to avoid interference with the inner water tray 300 .

[0114] The first support member 510 and the second support member 520 may be configured in one of the above two structures.

[0115] The air conditioner involved in the present application is provided with an external water receiving part 400 below the liquid inlet pipe 210 and the liquid outlet pipe 220. One end of the external water receiving part 400 is fixed to the outside of the outer shell 100. The upper water receiving part 410 is used to receive the liquid inlet pipe 210 located above, and the lower water receiving part 420 is used to receive the liquid outlet pipe 220 located below. The water in the upper water receiving part 410 is transported to the lower water receiving part 420 through the transition part 430, and finally transported to the internal water receiving tray 300 from the water guide pipe 441, and then discharged to the outside in a centralized manner.

[0116] The external water connection part 400 collects the condensed water formed on the liquid inlet pipe 210 and the liquid outlet pipe 220 and the water leakage at the pipe connection position to prevent it from dripping onto the ceiling and soaking the ceiling or even the furniture under the ceiling. It is safer and avoids losses to customers. It can be retrofitted and installed on the basis of the existing air conditioner and uses the drainage system of the internal water tray 300 for centralized drainage. There is no need to design an additional drainage pipe 310, and the modification cost is low.

[0117] On the other hand, the present application also proposes an air conditioner, which includes an outer shell 100 and a fan coil unit 200. An installation cavity is formed in the outer shell 100, and the fan coil unit 200 is arranged in the installation cavity.

[0118] The fan coil unit 200 is connected with a liquid inlet pipe group, a liquid outlet pipe group and a connecting pipe group.
