[0030] Currently, the internal structure of air-conditioning products is compact, and the size of the heat exchanger is restricted by the size of the housing, making it difficult to improve the heat exchange efficiency. How to increase the heat exchange area of the heat exchanger without increasing the volume of the indoor unit has become a key issue in improving the performance of the air-conditioning system.

[0031] Therefore, this technical solution proposes an indoor unit, including:

[0032] An indoor unit housing 100, including a chassis 110 and a first panel 120 connected to the chassis 110, with an air inlet 121 provided on the first panel 120;

[0033] An indoor-side heat exchanger 200, disposed on the chassis 110, corresponding to the inner side of the air inlet 121, and the indoor-side heat exchanger 200 is inclined relative to the air inlet 121.

[0034] Compared with the prior art, in the technical solution of the present utility model, the indoor unit includes an indoor unit housing 100, which includes a chassis 110 and a first panel 120 disposed on the chassis 110. An air inlet 121 is provided on the first panel 120, and an indoor-side heat exchanger 200 is also disposed on the chassis 110. The indoor-side heat exchanger 200 is opposite to the inner side of the air inlet 121, and the external air flow can enter the indoor-side heat exchanger 200 after entering the air inlet 121. In addition, the indoor-side heat exchanger 200 is inclined relative to the air inlet 121. Compared with the conventional solution where the heat exchanger is parallel to the air inlet 121, with the size of the air inlet 121 unchanged, the area of the heat exchanger facing the air inlet 121 can be designed to be larger. In this way, the contact area between the indoor-side heat exchanger 200 and the air flow at the air inlet 121 is increased, that is, the heat exchange area of the indoor-side heat exchanger 200 is increased, thereby improving the heat exchange efficiency of the indoor unit.

[0035] Such as Figures 1 to 3, in an embodiment of the present utility model, the indoor unit includes an indoor unit housing 100, the indoor unit housing 100 has a bottom plate and a first panel 120 disposed on one side of the chassis 110. The first panel 120 is connected to the chassis 110, and the first panel 120 can extend around the edge of the chassis 110. An air inlet 121 is formed on the first panel 120, and external air flow can enter the indoor unit housing 100 through the air inlet 121. In addition, an indoor heat exchanger 200 is also disposed on the chassis 110. The indoor heat exchanger 200 can be a condenser or an evaporator. The indoor heat exchanger 200 is opposite to the inner side position of the air inlet 121. The air flow entering the indoor unit housing 100 from the air inlet 121 can enter the indoor heat exchanger 200 and exchange heat to form a hot air flow or a cold air flow, and then be discharged from the indoor unit to realize the heating process or the cooling process. In order to improve the heat exchange efficiency, in this solution, the indoor heat exchanger 200 is inclined relative to the air inlet 121, and the inclination direction can be from the long side of the chassis 110 to the short side. In this way, when the size of the first panel 120 remains unchanged and the size of the air inlet 121 remains unchanged, a larger area of the windward side of the indoor heat exchanger 200 will be projected on the air inlet 121, and the size of the indoor heat exchanger 200 can be designed to be larger, so that the air flow at the air inlet 121 has a larger contact area with the indoor heat exchanger 200, thereby improving the heat exchange efficiency of the indoor unit.

[0036] In an embodiment of the present utility model, the indoor unit housing 100 further includes a top cover connected to the first panel 120, and the upper end of the indoor heat exchanger 200 extends to the top cover. The top cover is disposed at one end of the first panel 120 away from the chassis 110. The top cover, the first housing and the chassis 110 can be enclosed to form a complete outer shell of the indoor unit. The indoor heat exchanger 200 extends upward to the top cover, so that the overall size of the indoor heat exchanger 200 can be increased, which is also beneficial to increasing the contact area between the indoor heat exchanger 200 and the air flow at the air inlet 121 and improving the heat exchange efficiency of the indoor unit.

[0037] As Figure 2 , in an embodiment of the present utility model, the indoor unit further includes an air duct assembly 300 and a compressor assembly 400 disposed in the indoor unit housing 100;

[0038] The air duct assembly 300 and the indoor heat exchanger 200 are arranged side by side on the same side of the compressor assembly 400, and the air duct assembly 300 is disposed on the side of the indoor heat exchanger 200 away from the air inlet 121.

[0039] In this embodiment, the indoor heat exchanger 200 is an evaporator. The air duct assembly 300 is arranged side by side with the indoor heat exchanger 200. The air duct assembly 300 is arranged on the side of the indoor heat exchanger 200 away from the air inlet 121. The air flow can sequentially pass through the air inlet 121, the indoor heat exchanger 200, and the air duct assembly 300 in the same direction. Such an arrangement can make the air flow more smooth, reduce the wind resistance and operating noise. In addition, the indoor heat exchanger 200 and the compressor assembly 400 are arranged at two opposite angles of the chassis 110. In this way, the indoor heat exchanger 200 can be as far away from the compressor assembly 400 as possible, reducing the heat exchange between the two and ensuring the performance of the indoor unit. In addition, the indoor heat exchanger 200 and the air duct assembly 300 are arranged side by side on one side of the compressor assembly 400. In this way, the compactness of the indoor unit can be improved, which is beneficial to the miniaturization of the indoor unit.

[0040] As Figure 1 and Figure 2 , in an embodiment of the present utility model, the air duct assembly 300 includes a volute and an indoor fan arranged in the volute. The volute is provided with an air inlet portion 310 extending towards the indoor heat exchanger 200. An air inlet inclined port 320 is provided at one end of the air inlet portion 310 away from the volute. The air inlet inclined port 320 is arranged in parallel with the indoor heat exchanger 200. Among them, a spiral air duct is arranged in the volute to guide the external air flow along the optimal path. An indoor fan is arranged in the volute to drive the air flow in the volute. In addition, an air inlet portion 310 is arranged on the side of the volute facing the indoor heat exchanger 200. The air inlet portion 310 is used to guide the air flow passing through the indoor heat exchanger 200 into the volute. An air inlet inclined port 320 is arranged on the air inlet portion 310. The air inlet inclined port 320 is arranged in parallel with the indoor heat exchanger 200 to ensure that all the air flow can uniformly flow into the air inlet portion 310. The arrangement of the air inlet inclined port 320 can reduce the wind resistance when the air flow enters the volute from the indoor heat exchanger 200, make the air flow more smooth, thereby maximizing the heat exchange efficiency and reducing the operating noise at the same time.

[0041] As Figure 3, in an embodiment of the present utility model, the chassis 110 is provided with a water receiving tank 111 located below the indoor heat exchanger 200 and the air duct assembly 300; the indoor unit further includes moving wheels provided at the bottom of the chassis 110, and the chassis 110 is further provided with a wheel installation area 112 for connecting the moving wheels; the water receiving tank 111 and the wheel installation area 112 are arranged in a staggered manner; wherein, the water receiving tank 111 is opposite to the indoor heat exchanger 200 and the air duct assembly 300 in position, and the condensed water on the air duct assembly 300 and the condensed water droplets on the indoor heat exchanger 200 can be received by the water receiving tank 111 below after falling, and drainage holes can be provided in the water receiving tank 111 to drain the condensed water in the water receiving tank 111; wheel installation areas 112 can be provided at the four corner ends of the chassis 110, and each installation area can be connected with a moving wheel to facilitate the movement of the indoor unit; in addition, the positions of the wheel installation area 112 and the water receiving tank 111 are staggered, so that condensed water can be prevented from dripping onto the wheel installation area 112, preventing the wheel installation area 112 and the moving wheels from cooling down to generate condensed water, and improving the use experience of the indoor unit.

[0042] As Figure 3 , in an embodiment of the present utility model, the chassis 110 is further provided with a baffle 113, and the baffle 113 is arranged between the wheel installation area 112 and the water receiving tank 111; in this embodiment, the baffle 113 can be integrally formed with the chassis 110, and the baffle 113 completely separates the wheel installation area 112 from the water receiving tank 111, so that the water receiving tank 111 and the wheel installation area 112 are two independent areas on the chassis 110, so that condensed water can be prevented from dripping or splashing into the wheel installation area 112, further eliminating the hidden danger of generating condensed water on the wheel installation area 112 and the moving wheels, and improving the user experience.

[0043] In an embodiment of the present utility model, the indoor unit further includes a heat preservation member, and the heat preservation member covers the bottom of the chassis 110 and is opposite to the water receiving tank 111 in position. The heat preservation member can be heat preservation foam or foam, and the heat preservation member is fixed to the bottom of the chassis 110 and covers the area on the bottom of the chassis 110 that is directly opposite to the water receiving tank 111. Since the condensed water received by the water receiving tank 111 has a low temperature, the temperature of the position on the chassis 110 corresponding to the water receiving tank 111 is also lower than the room temperature. By attaching the heat preservation member at this position, the area of the chassis 110 can be heat-preserved, preventing external air from contacting this position to generate condensed water and dripping onto the ground, so that the use experience of the indoor unit can be improved.

[0044] In another embodiment of the present utility model, the area of the heat preservation member is not less than the area of the water receiving tank 111, and the area of the heat preservation member can be equivalent to the area of the water receiving tank 111, so that condensed water can be prevented from being generated in the area of the bottom of the chassis 110 corresponding to the water receiving tank 111; the area of the heat preservation member can also be larger than the area of the water receiving tank 111, so that the area around the water receiving tank 111 can be heat-preserved, further eliminating the hidden danger of generating condensed water.

[0045] The present utility model further provides an air conditioner, which includes an indoor unit and an outdoor unit. A refrigerant circuit is connected between the indoor unit and the outdoor unit to achieve heat exchange between the indoor unit and the outdoor unit. The specific structure of the indoor unit refers to the above-mentioned embodiments. Since this air conditioner adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated herein one by one.

[0046] In an embodiment of the present utility model, the indoor unit and the outdoor unit are connected by a flexible refrigerant pipe, and the flexible refrigerant pipe is pre-filled with refrigerant. Refrigerant can be pre-filled into the refrigerant circuit at the factory stage. During installation, only the air conditioner indoor unit and the air conditioner outdoor unit need to be fixed respectively, without the need to assemble the refrigerant pipe and add refrigerant, thereby reducing the installation difficulty and enabling personal installation by users. In addition, the use of a flexible refrigerant pipe also allows a certain relative displacement between the pipelines of the indoor unit and the outdoor unit, and can also ensure the tightness of the pipeline to prevent refrigerant leakage.
