[0047] Central air conditioning includes air conditioning indoor unit and air conditioning indoor unit. The air conditioning indoor unit is usually installed outdoors, and the air conditioning indoor unit is usually installed indoors. The air conditioning indoor unit and air conditioning indoor unit work together to realize the air conditioner's cooling, heating, dehumidification and air purification functions to achieve comfortable air quality.

[0048] In a central air conditioner, there is usually one indoor air conditioner, but the number of indoor air conditioners can be multiple. Each indoor air conditioner is provided with one or more air outlets to discharge the cooled, heated, dehumidified or purified air into the room through the air outlets. An indoor heat exchanger is usually provided in the indoor air conditioner, and an outdoor heat exchanger is usually provided in the indoor air conditioner. The indoor heat exchanger and the outdoor heat exchanger are usually connected through a refrigerant pipeline, so that the refrigerant can flow between the indoor heat exchanger and the outdoor heat exchanger.

[0049] During the cooling process of the central air conditioner, the indoor heat exchanger is the evaporator, and the refrigerant in the evaporator absorbs heat from liquid to gas. In the process of refrigerant evaporation and heat absorption, the evaporator exchanges heat with the air flowing through the evaporator, and takes away the heat in the air in the air-conditioning indoor unit, so that the air discharged from the air-conditioning indoor unit is the air after heat release and cooling, and the air-conditioning indoor unit blows cold air. At the same time, the outdoor heat exchanger is the condenser, and the refrigerant in the condenser changes from gas to liquid. In the process of refrigerant condensation and heat release, the condenser exchanges heat with the air in the air-conditioning indoor unit flowing through the condenser, so that the air in the air-conditioning indoor unit brings the heat of the condenser to the outside of the air-conditioning indoor unit, realizing the cooling process.

[0050] During the heating process of the central air conditioner, the outdoor heat exchanger is the evaporator, and the refrigerant in the evaporator absorbs heat from liquid to gas. In the process of refrigerant evaporation and heat absorption, the evaporator exchanges heat with the air flowing through the evaporator, and replaces the heat carried by the air in the air conditioner indoor unit with the refrigerant in the evaporator. At the same time, the indoor heat exchanger is the condenser, and the refrigerant in the condenser changes from gas to liquid. In the process of refrigerant condensation and heat release, the condenser exchanges heat with the air in the air conditioner indoor unit flowing through the condenser, so that the air in the air conditioner indoor unit takes away the heat carried by the condenser and discharges it from the air conditioner indoor unit to the room outside the air conditioner indoor unit, so that the indoor unit blows hot air, thereby realizing the heating process.

[0051] At present, the box body of the air-conditioning indoor unit is usually integrated, which leads to the large overall size and weight of the air-conditioning indoor unit, which will cause inconvenience to the operator during transportation and installation. In order to solve the problem that the air-conditioning indoor unit is inconvenient to transport and install, the present application proposes an air-conditioning indoor unit and an air conditioner having the air-conditioning indoor unit, by splitting the box body into a first box body part and a second box body part, so as to split the weight of the air-conditioning indoor unit into two parts, so that the operator can operate the first box body part and the second box body part separately during transportation and installation, thereby reducing the labor intensity of the operator. At the same time, since the box body is split into the first box body part and the second box body part, although the overall volume of the box body is not changed, the split structure can be placed in a variety of relative positions, thereby facilitating the transportation and installation of the air-conditioning indoor unit.

[0052] Combination Figures 1 to 4As shown, in some embodiments of the present application, the air-conditioning indoor unit 1 includes a housing 10 and functional devices, the housing 10 includes a first housing portion 11 and a second housing portion 12, the first housing portion 11 and the second housing portion 12 are connected in a detachable manner, some functional devices are connected to the first housing portion 11, and other functional devices are connected to the second housing portion 12.

[0053] Specifically, the functional device may include an electrical component, wherein the electrical components that account for a large weight in the air conditioner indoor unit 1 include an indoor heat exchanger component 20 and a fan component 30. In order to distribute the weight of the housing 10 after disassembly to the first housing portion 11 and the second housing portion 12, the indoor heat exchanger component 20 is connected to the first housing portion 11 and is disposed inside the first housing portion 11, and the fan component 30 is connected to the second housing portion 12 and is disposed inside the second housing portion 12.

[0054] According to the air-conditioning indoor unit 1 of the present application, during the transportation and installation process of the air-conditioning indoor unit 1, the box body 10 can be split into the first box body part 11 and the second box body part 12, the indoor heat exchanger assembly 20 is arranged in the first box body part 11, and the fan assembly 30 is arranged in the second box body part 12. By splitting the weight of the air-conditioning indoor unit 1 into two parts, the operator can operate the first box body part 11 and the second box body part 12 separately during the transportation and installation process, thereby reducing the labor intensity of the operator. At the same time, although the overall volume of the box body 10 does not change when the box body 10 is split into the first box body part 11 and the second box body part 12, the fan assembly 30 is arranged in the second box body part 12. Figure 2 In the vertical direction shown, the height dimensions of the first box body portion 11 and the second box body portion 12 after splitting are respectively smaller than the height dimension of the entire box body 10 before splitting. The first box body portion 11 and the second box body portion 12 after splitting can be arranged side by side in the horizontal direction, or placed in other relative positions, so as to facilitate the transportation and installation of the air-conditioning indoor unit 1.

[0055] In some embodiments of the present application, since the first box body portion 11 and the second box body portion 12 are detachable structures, and an indoor heat exchanger assembly 20 is provided inside the first box body portion 11, the first box body portion 11 can be connected to part of the gas furnace assembly to form a gas furnace with an indoor heat exchanger assembly 20.

[0056] Combination Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of the present application, the first box body 11 includes a first end 111 and a second end 112 that are oppositely disposed, and the first end 111 and the second end 112 can be connected to the second box body 12 respectively.

[0057] The first end 111 and the second end 112 are both provided with an open opening, thereby ensuring airflow between the inside and outside of the box body 10. The first end 111 and the second end 112 can be connected to the second box body 12 respectively, which can facilitate the first box body 11 and the second box body 12 to be assembled in various forms, thereby meeting various assembly requirements.

[0058] Specifically, in some embodiments of the present application, the functional device also includes a water receiving box 40, and at least part of the water receiving box 40 is arranged between the indoor heat exchanger assembly 20 and the first end 111; or, at least part of the water receiving box 40 is arranged between the indoor heat exchanger assembly 20 and the second end 112.

[0059] For the convenience of description, the embodiment of the present application is only illustrated by exemplifying that the water receiving box 40 is disposed between the indoor heat exchanger assembly 20 and the second end 112 .

[0060] like Figure 2 As shown, in some embodiments of the present application, the indoor heat exchanger assembly 20 includes a first heat exchange part 21, a second heat exchange part 22, a connecting plate 23 and at least one baffle 24. The first heat exchange part 21 and the second heat exchange part 22 are arranged at a first angle a, and a guide cavity is formed, and the end of the guide cavity opposite to the first angle a forms an open end. The value range of the first angle a is 0°<a<180°, that is, the first heat exchange part 21 and the second heat exchange part 22 are arranged in a roughly V-shaped structure, and a baffle 24 is arranged at the opening of at least one side of the V-shaped structure, so as to prevent the airflow from flowing into or out of the guide cavity through the side opening of the V-shaped structure. In some embodiments of the present application, baffles 24 can be respectively arranged at the openings on both sides of the V-shaped structure, so as to prevent the airflow from flowing into or out of the guide cavity through the openings on both sides of the V-shaped structure. At the same time, the ends of the first heat exchange part 21 and the second heat exchange part 22 that form the angle are connected by a connecting plate 23, so that the first heat exchange part 21 and the second heat exchange part 22 form a whole. The connecting plate 23 may include a first connecting plate and a second connecting plate, the first connecting plate is used to connect to the first heat exchange part 21, the second connecting plate is used to connect to the second heat exchange part 22, and the first connecting plate and the second connecting plate are connected to form the connecting plate 23 together.

[0061] Since condensed water may be formed in the process of heat exchange between the first heat exchange part 21 and the second heat exchange part 22 and the airflow, a water receiving box 40 needs to be provided below the indoor heat exchanger assembly 20, and the water receiving box 40 corresponds to the open end of the guide cavity.

[0062] like Figure 2 As shown, in some embodiments of the present application, the water receiving box 40 further includes a water outlet 43 , which is connected to an external pipeline of the housing 10 to discharge condensed water in the water receiving box 40 to the outside of the housing 10 .

[0063] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present application, the air conditioner indoor unit 1 adopts the installation mode of bottom air intake and top air outlet. At this time, the first box body 11 is connected to the second box body 12 through the first end 111. Specifically, the second box body 12 includes a third end 121 and a fourth end 122, and the third end 121 and the fourth end 122 are respectively provided with an open port, so as to ensure the air flow between the inside and the outside of the box 10. Among them, the fourth end 122 is arranged opposite to the air outlet end of the fan assembly 30, and the fourth end 122 is provided with the air outlet of the air conditioner indoor unit 1, and the third end 121 is used to connect with the first end 111, and at this time, the second end 112 forms the air inlet of the air conditioner indoor unit 1. The fan assembly 30 may include a vortex fan and a volute, and the volute is mounted on the outside of the vortex fan. When the vortex fan rotates, an airflow can be formed inside the box body 10, thereby sucking the airflow outside the box body 10 into the inside of the box body 10 through the air inlet on the side where the indoor heat exchanger assembly 20 is located. After the airflow sucked into the inside of the box body 10 exchanges heat with the indoor heat exchanger assembly 20, it is discharged to the outside of the box body 10 through the air outlet on the side where the fan assembly 30 is located.

[0064] Combination Figure 3 and Figure 5 As shown, in some embodiments of the present application, the air conditioner indoor unit 1 adopts the installation mode of top air intake and bottom air outlet. At this time, the air conditioner indoor unit 1 needs to be turned 180° as a whole. In the prior art, in order to make the water receiving box 40 continue to be arranged below the indoor heat exchanger assembly 20, it is necessary to remove the indoor heat exchanger assembly 20 and the water receiving box 40 from the second box body 12 respectively, and then assemble the water receiving box 40 and the indoor heat exchanger assembly 20 in sequence, so that the water receiving box 40 is along the Figure 5 The direction shown is set below the indoor heat exchanger assembly 20. In the present application, since the first end 111 and the second end 112 can be connected to the third end 121 respectively, there is no need to disassemble the indoor heat exchanger assembly 20 and the water receiving box 40. The first box body 11 is turned 180° to connect the second end 112 to the third end 121. Figure 5 The installation state of the indoor unit 1 of the air conditioner realizes the conversion from the bottom air intake state to the top air intake state, and the water receiving box 40 is arranged below the indoor heat exchanger assembly 20 in the vertical direction to collect condensed water. Figure 5 The water receiving box 40 is arranged inside the first box body 11, and only the water outlet end 43 extends to the outside of the first box body 11.

[0065] Combination Figure 2 and Figure 3As shown, in some embodiments of the present application, the water receiving box 40 includes a first water receiving portion 41 and a second water receiving portion 42, the first water receiving portion 41 is arranged opposite to the first end 111 or the second end 112, and the side wall between the first end 111 and the second end 112 is arranged opposite to the second water receiving portion 42.

[0066] Specifically, since the open end formed by the first heat exchange portion 21 and the second heat exchange portion 22 is disposed toward the second end portion 112, the first water receiving portion 41 is disposed opposite to the second end portion 112 and is disposed between the second end portion 112 and the indoor heat exchanger assembly 20. The second water receiving portion 42 is disposed to intersect with the first water receiving portion 41 and is disposed opposite to the side wall of the first housing portion 11. Figure 2 When the position shown is rotated 90° or flipped 90° and horizontal air inlet and outlet are adopted, the second water receiving portion 42 can be adjusted to be arranged relative to different side walls of the first box body portion 11, and the second water receiving portion 42 can be arranged below the indoor heat exchanger assembly 20 in the vertical direction, so as to collect condensed water through the second water receiving portion 42.

Specifically, the fixing portion 51 may be provided near the third end portion 121, and the fixing portion 51 may be fixed to the outer surface of the second box portion 12 by screws. The outer surface of the first box portion 11 is provided with a first groove portion 113, and the connecting portion 52 includes a main board portion 521 and an extension end 522, one end of the main board portion 521 is rotatably connected to the fixing portion 51, and the other end of the main board portion 521 is provided with an extension end 522, and the extension end 522 is provided at an angle with the main board portion 521, so that the extension end 522 is conveniently snapped into the first groove portion 113, and then the first box portion 11 and the second box portion 12 are fixedly connected through the connecting member 50.

[0071] The first box body 11 is provided with a plurality of first grooves 113 at positions near the first end 111 and at positions near the second end 112. The protruding end 522 can be respectively engaged with the first grooves 113 at the positions near the two ends of the first box body 11, so that the first end 111 and the second end 112 are respectively connected to the second box body 12. The second box body 12 is also provided with a second groove 123, which is arranged near the third end 121. The main board 521 and the fixing part 51 can be connected by a rotating shaft, which can be a part of the main board 521 or the fixing part 51, or the rotating shaft is a separate structure, and the main board 521 and the fixing part 51 are sequentially passed through. The second groove 123 is used to accommodate the rotating shaft, so that the main board 521 and the fixing part 51 after connection are respectively fitted with the outer surface of the box body 10, reducing the generation of the external protruding structure of the box body 10, and further reducing the scratch phenomenon caused by the existence of the protruding structure.
