[0046] In the related art, the air inlet and air outlet directions of the traditional split-type air conditioner indoor unit cannot be changed because the positions of the air outlet and the air inlet are fixed. In addition, since the internal water collection pan design structure of the traditional split-type air conditioner indoor unit cannot meet both vertical and horizontal installation modes, when the traditional split-type air conditioner indoor unit is converted from vertical installation to horizontal installation, the air inlet and air outlet of the indoor unit will be blocked, and condensation water leakage may also occur inside the indoor unit. Therefore, the traditional split-type air conditioner indoor unit can only be assembled in a fixed installation method, which cannot meet a variety of different installation scenarios, reducing the adaptability of the air conditioner.

[0047] Reference below Figure 1-Figure 8 An indoor unit for an air conditioner according to an embodiment of the present invention is described.

[0048] The indoor unit 100 for an air conditioner according to the present invention comprises: a housing 11, a wind wheel assembly 12 and a transfer assembly, wherein the housing 11 is formed with a first wall 111 and a second wall 112, the first wall 111 and the second wall 112 are arranged adjacent to each other, a first air port 101 is formed on the first wall 111, and a second air port 102 is formed on the second wall 112; the wind wheel assembly 12 is arranged in the housing 11, a wind wheel cavity 105 is formed in the wind wheel assembly 12, and the wind wheel cavity 105 is communicated with the first air port 101 and the second air port 102 respectively; the transfer assembly A transfer air duct 153 is formed in the component, and the transfer component is arranged on the first wall 111 or the second wall 112; when the transfer component is arranged on the first wall 111, the inlet of the transfer air duct 153 is connected with the wind wheel cavity 105, and the outlet of the transfer air duct 153 is oriented in the same direction as the second air port 102 and serves as the air outlet 103; when the transfer component is arranged on the second wall 112, the outlet of the transfer air duct 153 is connected with the wind wheel cavity 105, and the inlet of the transfer air duct 153 is oriented in the same direction as the first air port 101 and serves as the return air port 104.

[0049] In some specific embodiments, the indoor unit 100 is mainly composed of a shell 11, a wind wheel assembly 12 and a switching assembly. A first wall 111 and a second wall 112 are respectively formed on two adjacent sides of the shell 11. One end of the first wall 111 is connected to one end of the second wall 112. A first air outlet 101 is formed on the first wall 111, and a second air outlet 102 is formed on the second wall 112. The first air outlet 101 and the second air outlet 102 can be connected to the external environment respectively, so that the airflow in the external environment can pass through the first air outlet. 101 or the second air outlet 102 enters into the shell 11, and a wind wheel assembly 12 is also arranged inside the shell 11. There is a gap between the wind wheel assembly 12 and the inner wall of the shell 11, and a wind wheel cavity 105 is formed in the wind wheel assembly 12. The wind wheel cavity 105 is connected with the first air outlet 101 and the second air outlet 102 respectively, and the wind wheel cavity 105 is also connected with the external environment. The wind wheel assembly 12 can discharge the airflow cooled or heated by other equipment in the shell 11 to the external environment, so as to adjust the temperature of the external environment.

[0050] The adapter assembly can be arranged on the first wall 111 or the second wall 112. When the indoor unit 100 is installed vertically, the wind wheel cavity 105 discharges air in a direction perpendicular to the first wall 111. The adapter assembly is arranged on the first wall 111. A horizontally extending adapter air duct 153 is formed in the adapter assembly. The inlet of the adapter air duct 153 is connected to the wind wheel cavity 105. The outlet of the adapter air duct 153 is in the same direction as the second air outlet 102. The outlet of the adapter air duct 153 can be used as the air outlet 103. The adapter assembly can change the air outlet direction of the wind wheel cavity 105 from a vertical direction to a horizontal direction, and discharge air in the direction of the second air outlet 102. When the indoor unit 100 is installed horizontally, the adapter assembly is arranged on the second wall 112, and the adapter air duct 153 formed in the adapter assembly can be used as a return air duct. The inlet of the adapter air duct 153 is in the same direction as the first air outlet 101. The airflow in the external environment can enter the shell 11 from the first air outlet 101 and the inlet of the adapter air duct 153. The outlet of the adapter air duct 153 is connected to the wind wheel cavity 105 to ensure the air intake in the wind wheel cavity 105.

[0051] Therefore, when the indoor unit 100 in the present application is converted from a vertical installation to a horizontal installation or from a horizontal installation to a vertical installation, the return air outlet 104 and the air outlet 103 will not be blocked, which can effectively ensure the air intake and air outlet of the indoor unit 100, so that the air conditioner can be installed in two different installation methods, horizontal and vertical, thereby improving the adaptability of the air conditioner and enhancing the universality of the air conditioner.

[0052] According to the present invention, the indoor unit 100 is provided with adjacent first wall 111 and second wall 112 on the shell 11, and the adapter assembly is arranged on the first wall 111 or the second wall 112. When the indoor unit 100 is installed vertically, the wind wheel cavity 105 discharges air in a direction perpendicular to the first wall 111, and the adapter assembly is arranged on the first wall 111. A horizontally extending adapter air duct 153 is formed in the adapter assembly, and the inlet of the adapter air duct 153 is connected to the wind wheel cavity 105, and the outlet of the adapter air duct 153 is in the same direction as the second air outlet 102. The outlet of the adapter air duct 153 can be used as the air outlet 103, and the adapter assembly can change the air outlet direction of the wind wheel cavity 105 from a vertical direction to a horizontal direction, and discharge air in the direction of the second air outlet 102. When the indoor unit 100 is installed horizontally, the adapter assembly is arranged on the second wall 112, and the adapter air duct 153 formed in the adapter assembly can be used as a return air duct. The inlet of the adapter air duct 153 is in the same direction as the first air outlet 101, and the airflow in the external environment can enter the housing 11 from the first air outlet 101 and the inlet of the adapter air duct 153. The outlet of the adapter air duct 153 is connected with the wind wheel cavity 105 to ensure the air intake in the wind wheel cavity 105. When the indoor unit 100 is converted from vertical installation to horizontal installation or from horizontal installation to vertical installation, the return air outlet 104 and the air outlet 103 will not be blocked, which can effectively ensure the air intake and air outlet of the indoor unit 100. The air conditioner can be installed in two different installation methods, horizontal and vertical, which improves the adaptability of the air conditioner and improves the universality of the air conditioner.

[0053] According to some embodiments of the present invention, when the adapter assembly is arranged on the first wall 111, the end face of the air outlet 103 is located in the same plane as the first wall 111; when the adapter assembly is arranged on the second wall 112, the end face of the return air outlet 104 is located in the same plane as the second wall 112, so that the outer surface morphology of the indoor unit 100 is consistent, and the indoor unit 100 can be assembled into the outdoor unit more conveniently and quickly, thereby improving the assembly efficiency of the indoor unit 100 of the air conditioner.

[0054] According to some embodiments of the present invention, when the adapter assembly is disposed on the first wall 111, the adapter assembly includes: an adapter shell 15 and an air guide plate 151, an adapter air duct 153 is formed in the adapter shell 15, and the adapter shell 15 is fixed to the first wall 111; the air guide plate 151 can be pivotally disposed on the adapter shell 15 to selectively adjust the air outlet direction of the air outlet 103.

[0055] In some specific embodiments, when the adapter assembly is arranged on the first wall 111, the adapter assembly is composed of an adapter housing 15 and an air guide plate 151, the adapter housing 15 is arranged on the first wall 111, and the adapter housing 15 is formed with an air inlet on a side facing the wind wheel assembly 12, and the adapter housing 15 is formed with an air outlet 103 on a side facing the second air outlet 102, the air inlet can be connected to the wind wheel cavity 105, the air outlet 103 can be connected to the external environment, and a horizontally extending adapter air duct 153 is formed between the air outlet 103 and the first air inlet. The switching air duct 153 can horizontally guide the airflow in the wind wheel cavity 105 to the air outlet 103. The air guide plate 151 can be pivotally set on the air outlet 103. The user can adjust the angle formed between the air guide plate 151 and the first wall 111, thereby adjusting the air outlet direction of the air outlet 103, so that the airflow is more evenly distributed in the room, avoiding the airflow from blowing directly to the human body or a specific area, so that the cold air or warm air generated in the indoor unit 100 can better cover the entire room, improve the cooling or heating effect of the air conditioner, and enhance the user experience.

[0056] According to some embodiments of the present invention, when the adapter assembly is disposed on the second wall 112, the adapter assembly includes: an adapter shell 15, in which a adapter air duct 153 connected to the second air outlet 102 is formed, and the adapter shell 15 and the shell 11 are constructed as an integral shell; and a support foot 152, which is disposed at the bottom of the second wall 112.

[0057] In some specific embodiments, when the adapter assembly is arranged on the second wall 112, the adapter assembly is composed of an adapter shell 15 and a support foot 152. The adapter shell 15 is arranged on the second wall 112. The adapter shell 15 can be constructed as an integral structure with the shell. On the one hand, it is convenient to assemble and disassemble the adapter assembly. On the other hand, it can reduce the number of processing parts of the internal machine 100 and reduce the manufacturing cost. A support foot 152 is arranged between the second wall 112 and the bottom wall of the adapter shell 15. The support foot 152 can support the second wall 112, so that a certain space is left between the second wall 112 and the bottom wall of the adapter shell 15 to form a transfer air duct 153. The outlet of the transfer air duct 153 is directly connected to the bottom wall of the adapter shell 15. The evaporator is arranged so that the inlet of the adapter air duct 153 has the same direction as the first air outlet 101, and the adapter air duct 153 is connected with the second air outlet 102, so that the airflow can flow into the evaporator from the first air outlet 101 and the inlet of the adapter air duct 153 respectively. In addition, since the inlet of the adapter air duct 153 is relatively narrow, the airflow flowing into the shell 1111 from the first air outlet 101 can flow into the adapter air duct 153 through the second air outlet 102, so as to increase the airflow rate flowing into the evaporator from the adapter air duct 153, so that the air intake volume in the shell 11 is basically the same when the indoor unit 100 is assembled horizontally and when it is assembled vertically, thereby ensuring the cooling effect and cooling efficiency of the indoor unit 100 when the indoor unit 100 is installed horizontally.

[0058] According to some embodiments of the present invention, the indoor unit 100 further includes: an evaporator, which is accommodated in the shell 11 and disposed between the shell 11 and the wind wheel assembly 12 .

[0059] In some specific embodiments, an evaporator is further provided inside the shell 11. The evaporator is arranged between the inner wall of the shell 11 and the wind wheel assembly 12. The evaporator can convert liquid low-temperature refrigerant into gas or mist. The liquid low-temperature refrigerant will absorb heat in the process of converting into gas or mist, so that the temperature of the evaporator will drop. When the air flow from the external environment into the shell 11 flows through the evaporator, the evaporator will absorb heat in the air flow, so that the temperature of the air flow drops and becomes cold air. The cold air enters the wind wheel cavity 105 through the gap between the wind wheel assembly 12 and the inner wall of the shell 11, and then flows from the wind wheel cavity 105 to the air outlet 103 and is guided into the room, thereby realizing cooling in the room.

[0060] According to some embodiments of the present invention, the evaporator includes: a first evaporator 13 and a second evaporator 14, the first evaporator 13 and the second evaporator 14 extend away from each other in a direction away from the second wall 112, and the wind wheel assembly 12 is arranged between the first evaporator 13 and the second evaporator 14.

[0061] In some specific embodiments, a first evaporator 13 and a second evaporator 14 are provided in the shell 11. The two evaporators can absorb more and faster the heat in the airflow entering the shell 11, so that the temperature of the airflow entering the shell 11 drops quickly, thereby improving the refrigeration efficiency and refrigeration effect of the air conditioner. The first evaporator 13 is obliquely arranged between the first wall 111 and the second wall 112, and the second evaporator 14 is obliquely arranged between the second wall 112 and the side wall of the shell 11 opposite to the first wall 111. The first evaporator 13 and the second evaporator 14 extend away from each other in a direction away from the second wall 112. A certain space is formed between the first evaporator 13 and the second evaporator 14 for accommodating the wind wheel assembly 12, so that the airflow cooled by the first evaporator 13 and the second evaporator 14 can enter the wind wheel assembly 12 at the same time, thereby increasing the flow rate of the cooling airflow in the wind wheel cavity 105, increasing the flow rate of the cooling airflow discharged into the room, and improving the cooling effect in the room.

[0062] According to some embodiments of the present invention, a plurality of second air vents 102 are disposed on the second wall 112 , at least one second air vent 102 is directly opposite to the first evaporator 13 , and at least another one is directly opposite to the second evaporator 14 .

[0063] In some specific embodiments, two second air outlets 102 arranged in parallel are formed on the second wall 112, and the airflow in the external environment can enter into the shell through the two second air outlets 102 respectively, thereby increasing the air intake inside the shell. One of the second air outlets 102 is arranged directly opposite to the first evaporator 13, and the other second air outlet 102 is arranged in parallel with the second evaporator 14, so that the airflow entering the shell from one of the second air outlets 102 can be directly blown to the first evaporator 13, and the airflow entering the shell from the other second air outlet 102 can be directly blown to the second evaporator 14, and the airflow is cooled in the first evaporator 13 and the second evaporator 14 at the same time, thereby increasing the cooling airflow flow in the wind wheel cavity 105 and improving the cooling efficiency and cooling effect of the air conditioner.

[0064] According to some embodiments of the present invention, a plurality of first air outlets 101 are disposed on the first wall 111 , at least one first air outlet 101 is directly opposite to the first evaporator 13 , and at least another first air outlet 101 is connected to the wind wheel cavity 105 .

[0065] In some specific embodiments, when the adapter assembly is disposed on the second wall 112, two first air outlets 101 are disposed on the first wall 111, wherein one of the first air outlets 101 is disposed opposite to the first evaporator 13, and the other first air outlet 101 is connected to the wind wheel cavity 105 and serves as an air outlet 103, so that the airflow entering the shell from one of the first air outlets 101 can be directly blown to the first evaporator 13 for cooling. After the cooled airflow enters the wind wheel cavity 105, it is guided into the room by the other first air outlet 101 to adjust the temperature in the room.
