[0045] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement.

[0046] Currently, most commercial and household air conditioning systems use a blower wheel to achieve air circulation and distribution, thereby meeting the cooling or heating requirements of the indoor space. The centrifugal blower wheel is a commonly used blower wheel. The structure of the centrifugal blower wheel determines that its air volume output is limited and it is difficult to meet the requirements of large-area rooms. In addition, due to the low air pressure of the centrifugal blower wheel, the air supply distance is short. During actual use, the temperature difference between the area near the air outlet of the air conditioner and the area far from the air outlet is large, which is not conducive to improving the cooling and heating effects.

[0047] In view of this, the embodiments of the present utility model provide an indoor unit of an air conditioner and an air conditioner. By replacing the centrifugal blower wheel with a cross-flow blower wheel, the air can be sent to a farther distance, making the indoor temperature distribution more uniform. Moreover, during the air supply process of the cross-flow blower wheel, the air flow loss in the air duct is small, which is conducive to improving the energy efficiency ratio of the air conditioner. It can be understood that by using the cross-flow blower wheel, the air supply volume and the air supply distance can be increased, which can effectively improve the cooling or heating effect of the air conditioner and enhance the user comfort. In addition, in the present application, the compressor is arranged indoors, that is, integrated in the indoor unit of the air conditioner, which can reduce the weight of the outdoor unit of the air conditioner, thereby facilitating the installation of the outdoor unit of the air conditioner. At the same time, since the outdoor unit of the air conditioner usually needs to be fixed on a bracket, the reduction of the weight of the outdoor unit of the air conditioner can reduce the pressure on the bracket and prevent the bracket from cracking due to excessive pressure, thereby improving the service life of the bracket. And, the compressor and the cross-flow blower wheel are arranged in the vertical direction, increasing the overall height of the indoor casing, and the height of the air outlet will also be increased. The cold air or warm air can better mix with the indoor air, which helps to form a more uniform temperature distribution, thereby enhancing the cooling or heating effect.

[0048] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the accompanying drawings.

[0049] AsFigures 1 to 3 As shown in Figures 1 to 3 , an embodiment of the present utility model provides an indoor unit of an air conditioner, which includes:

[0050] An indoor unit housing 10, an installation cavity is formed inside the indoor unit housing 10, and a relatively enclosed space can be provided through the installation cavity to facilitate the installation of other components. The indoor unit housing 10 is provided with an air inlet 11 and an air outlet 12 communicating with the installation cavity. It can be understood that after the air flow enters the installation cavity from the air inlet 11, it then flows out from the air outlet 12, thereby realizing the circulating flow of air. Optionally, the air inlet 11 is arranged at the rear side of the indoor unit housing 10, and the air outlet 12 is arranged at the front side of the indoor unit housing 10. In one embodiment, multiple air inlets 11 can be arranged, and multiple air outlets 12 can also be arranged, so as to increase the air inlet or outlet area and accelerate the circulating flow of air. Specifically, the indoor unit housing 10 can be a plastic part, with a lighter weight and lower cost. Of course, in other embodiments, the indoor unit housing 10 can also be a sheet metal part, which is not limited here. To facilitate the installation of other components inside the installation cavity, the indoor unit housing 10 can include a front shell and a rear shell that are detachably connected. The front shell and the rear shell jointly enclose the installation cavity, and the front shell and the rear shell can be detachably connected by means such as buckles and bolts;

[0051] A cross-flow fan 20, which is arranged in the installation cavity and located between the air inlet 11 and the air outlet 12. By arranging the cross-flow fan 20, the air flow from the air inlet 11 towards the air outlet 12 can be accelerated, and the circulating flow of air is accelerated, which is beneficial to improving the refrigeration and heating effects. It can be understood that the cross-flow fan 20 rotates at a high speed in the installation cavity, attracting the air flow to flow into the installation cavity from the air inlet 11 and flowing out from the air outlet 12;

[0052] A compressor 30, which is arranged below the cross-flow fan 20, and the compressor 30 can realize the transfer of thermal energy. The compressor 30 is arranged indoors, that is, integrated in the indoor unit of the air conditioner, which can reduce the weight of the outdoor unit of the air conditioner, thereby facilitating the installation of the outdoor unit of the air conditioner. At the same time, since the outdoor unit of the air conditioner usually needs to be fixed on a bracket, the reduction of the weight of the outdoor unit of the air conditioner can reduce the pressure on the bracket and prevent the bracket from cracking due to excessive pressure, thereby improving the service life of the bracket. Since the compressor 30 will generate noise or vibration during operation, for this reason, a damping structure, such as rubber and plastic, can be arranged at the bottom of the compressor 30 to absorb vibration. A sound insulation cover can also be arranged outside the compressor 30 to absorb or reduce noise, making the indoor environment relatively quiet, reducing the impact of noise on users, and providing a comfortable rest environment for users.

[0053] In the technical solution adopted in this embodiment, the cross-flow impeller 20 is provided, which has a relatively high air pressure and can send the air to a farther distance, making the indoor temperature distribution more uniform. Moreover, during the air supply process of the cross-flow impeller 20, the air flow loss in the air duct is relatively small, which is beneficial to improving the energy efficiency ratio of the air conditioner. It can be understood that the cross-flow impeller 20 can increase the air supply volume and the air supply distance, effectively improving the refrigeration or heating effect of the air conditioner and enhancing the user comfort. In addition, in this application, the compressor 30 is arranged indoors, that is, integrated in the indoor unit of the air conditioner, which can reduce the weight of the outdoor unit of the air conditioner, thus facilitating the installation of the outdoor unit of the air conditioner. At the same time, since the outdoor unit of the air conditioner usually needs to be fixed on a bracket, the reduction of the weight of the outdoor unit of the air conditioner can reduce the pressure on the bracket and prevent the bracket from cracking due to excessive pressure, thereby improving the service life of the bracket. And, the compressor 30 and the cross-flow impeller 20 are arranged in the vertical direction, increasing the overall height of the indoor casing 10, and the height of the air outlet 12 will also be increased, so that the cold air or warm air can better mix with the indoor air, contributing to the formation of a more uniform temperature distribution, and further enhancing the refrigeration or heating effect.

[0054] In an embodiment of the present utility model, the cross-flow impeller 20 is vertically arranged in the installation cavity. The height of the air outlet 12 of the existing air conditioner is relatively low, which affects the air supply distance. For this reason, in this embodiment, the cross-flow impeller 20 is vertically arranged. In this way, the height of the entire indoor casing 10 is increased, and the height of the air outlet 12 is also increased accordingly, which is beneficial to increasing the air supply distance and further enhancing the refrigeration and heating effects. Moreover, the air outlet 12 at a higher position can prevent the cold air from directly blowing on the human body, reducing the direct impact on the human body and enhancing the comfort. At the same time, the air outlet 12 at a higher position can reduce the interference of furniture, decorations, etc. on the air flow, ensuring that the air conditioning system can operate efficiently without being affected by physical obstacles.

[0055] In an embodiment of the present utility model, referring to Figure 2 , the indoor unit of the air conditioner further includes a wind guiding component 40 for changing the air outlet direction of the air outlet 12. The wind guiding component 40 is rotatably arranged in the installation cavity and corresponds to the air outlet 12. In this way, the air outlet direction and the air outlet angle of the air outlet 12 can be adjusted through the wind guiding component 40, facilitating the user to adjust the wind direction according to personal preferences or room layout, avoiding the air flow from directly blowing on the human body, and improving the comfort.

[0056] In an embodiment of the present utility model, referring to Figure 2, the air guiding assembly 40 includes a plurality of louvers 41 extending horizontally and rotatable; and / or, the air guiding assembly 40 includes a plurality of air guiding plates 42 extending vertically and rotatable. It can be understood that through the arrangement of the louvers 41 and the air guiding plates 42, the adjustment methods of the air outlet direction are increased, and the adjustment by the user is more flexible, effectively improving the user experience. In one embodiment, the louvers 41 and the air guiding plates 42 can be driven to rotate by a motor, which will not be elaborated here.

[0057] In one embodiment of the present utility model, referring to Figure 2 and Figure 3 , the air conditioner indoor unit further includes a volute 50. The volute 50 has an air duct 51 communicating the air inlet 11 and the air outlet 12. The cross-flow fan 20 is arranged in the air duct 51, and the air guiding assembly 40 is arranged at the outlet of the air duct 51. The main function of the volute 50 is to guide the air flow, so that the air flow flows in the designed direction and speed, that is, from the air inlet 11 to the air outlet 12, which can improve the air supply efficiency of the air conditioner and ensure that the air flow is evenly distributed to the area to be covered. In addition, the volute 50 can increase the pressure of the air flow, and the air flow flowing out from the air outlet 12 can be sent farther, thereby improving the air supply distance and coverage range of the air conditioner and effectively enhancing the refrigeration and heating effects.

[0058] In one embodiment of the present utility model, referring to Figure 2 , the air conditioner indoor unit further includes an indoor side heat exchanger 60. The indoor side heat exchanger 60 is arranged between the cross-flow fan 20 and the air inlet 11. Through the indoor side heat exchanger 60, the air flowing in from the air inlet 11 can be heated or cooled, so that the air flows out from the air outlet 12 after being heated or cooled, realizing the adjustment of the indoor temperature.

[0059] In one embodiment of the present utility model, referring to Figure 2 , the air conditioner indoor unit further includes a water receiving tray 71. The water receiving tray 71 is connected to the indoor unit housing 10 and is arranged below the indoor side heat exchanger 60. Condensate will be generated when the indoor side heat exchanger 60 is working. To prevent the condensate from flowing around, the water receiving tray 71 is provided. In this embodiment, the water receiving tray 71 is arranged below the indoor side heat exchanger 60, and the condensate generated by the indoor side heat exchanger 60 can directly drip into the water receiving tray 71 under the action of gravity, thereby realizing the collection of the condensate and preventing the condensate from flowing around and causing a short circuit in the circuit or soaking electronic components. In one embodiment, the water receiving tray 71 is arranged between the compressor 30 and the indoor side heat exchanger 60 and is connected to the indoor unit housing 10. Specifically, the water receiving tray 71 can be fixed to the inner wall of the indoor unit housing 10 by bolts or buckles.

[0060] In one embodiment of the present utility model, referring to Figure 5, the air conditioner indoor unit further includes a water collection box 72. The water collection box 72 is arranged on one side of the compressor 30 and below the water receiving tray 71. The water collection box 72 is communicated with the water receiving tray 71 through a pipeline. The capacity of the water receiving tray 71 is limited, and the condensed water in the water receiving tray 71 needs to be discharged in time. For this purpose, in this embodiment, the water collection box 72 is provided. The water collection box 72 is connected to the water receiving tray 71 through a pipeline, so that the condensed water in the water receiving tray 71 flows into the water collection box 72, and the condensed water in the water receiving tray 71 is discharged in time. Optionally, the water collection box 72 is arranged below the water receiving tray 71. In this way, the condensed water in the water receiving tray 71 can directly flow into the water collection box 72 under the action of gravity, and the structure is simpler. In one embodiment, the indoor unit housing 10 can be provided with a pipeline outlet to facilitate the discharge of the condensed water in the water collection box 72 through a pipeline. In other embodiments, a maintenance port can also be provided on the indoor unit housing 10. A detachable maintenance board is provided at the maintenance port. By removing the maintenance board, the water collection box 72 can be taken out from the installation cavity, so as to pour out the condensed water in the water collection box 72, which is simple and convenient.

[0061] In an embodiment of the present utility model, the air conditioner indoor unit further includes a drainage assembly for discharging the condensed water of the water collection box 72. The drainage assembly is arranged at the bottom of the indoor unit housing 10. In this way, the condensed water in the water collection box 72 can be automatically discharged through the drainage assembly, reducing the workload of the user.

[0062] In an embodiment of the present utility model, referring to Figure 2 , the drainage assembly includes a water pump 81. The water pump 81 is arranged at the bottom of the indoor unit housing 10 for discharging the condensed water of the water collection box 72. It can be understood that the water inlet of the water pump 81 is connected to the water collection box 72 through a pipeline, and the water outlet of the water pump 81 extends to the outside of the indoor unit housing 10 through a pipeline and can be connected to the air conditioner outdoor unit or directly extend to the outside. This is not limited here. In this way, the condensed water in the water collection box 72 can be automatically pumped out and discharged through the water pump 81, replacing the direct operation of the user.

[0063] And / or, the drainage assembly includes a liquid level monitor 82, which is arranged inside the water collection box 72. By setting the liquid level monitor, the liquid level condition of the condensed water in the water collection box 72 can be monitored in real time. When the preset liquid level is reached, the water collection box 72 is drained in time to prevent the condensed water in the water collection box 72 from overflowing. In one embodiment, the air conditioner indoor unit further includes a controller, and the controller is connected to the liquid level monitor 82 and the water pump 81. The controller controls the opening or closing of the water pump 81 according to the monitoring situation of the liquid level monitor 82 to realize automatic drainage.

The indoor unit of the air conditioner is configured as the indoor unit of the air conditioner described above. Specifically, for the specific structure of the indoor unit of the air conditioner, refer to the above embodiment. Since this air conditioner adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, and will not be elaborated here one by one.

[0068] It should be noted that the air conditioner of the present invention can be a split air conditioner that is convenient for the user to realize personal installation. It uses a refrigerant pipe to connect the indoor heat exchanger 60 and the outdoor heat exchanger, and injects refrigerant into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the indoor unit of the air conditioner and the outdoor unit of the air conditioner respectively, without the need to assemble the refrigerant pipes and add refrigerant, thereby reducing the installation difficulty and realizing personal installation by the user.
