Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of 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, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state 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 heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

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.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

An air conditioner indoor unit 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 11. The air conditioner indoor unit 100 may be a wall-mounted air conditioner indoor unit. In the following description of the present application, the air conditioner indoor unit 100 is exemplified as a wall-mounted air conditioner indoor unit. Of course, the air conditioner indoor unit 100 may be other types of air conditioner indoor units, and is not limited to a wall-mounted air conditioner indoor unit.

As shown in fig. 1 to 11, an air conditioner indoor unit 100, such as a wall-mounted air conditioner indoor unit, according to an embodiment of the present invention includes a casing 1, a first air duct assembly 4, a second air duct assembly 5, a first heat exchanger 6, a second heat exchanger 7, a first fan 8, a second fan 9, a first wind sweeping assembly 10, and a second wind sweeping assembly 20.

Specifically, the casing 1 is formed with an air inlet, a first air outlet 11 and a second air outlet 12, the first air outlet 11 is provided with two first air deflectors 2 to jointly adjust the direction of the air flow blown out from the first air outlet 11, and the second air outlet 12 is provided with two second air deflectors 3 to jointly adjust the direction of the air flow blown out from the second air outlet 12. The first air duct assembly 4 and the second air duct assembly 5 are both arranged in the machine shell 1, the first air duct assembly 4 is provided with a first air outlet channel 41, the first air outlet channel 41 is communicated with the first air outlet 11, the second air duct assembly 5 is provided with a second air outlet channel 51, and the second air outlet channel 51 is communicated with the second air outlet 12. The first heat exchanger 6 is arranged between the air inlet and the first air duct assembly 4, the second heat exchanger 7 is arranged between the air inlet and the second air duct assembly 5, and the first heat exchanger 6 and the second heat exchanger 7 work independently. The first fan 8 is positioned on one side of the first heat exchanger 6 adjacent to the first air outlet 11, the second fan 9 is positioned on one side of the second heat exchanger 7 adjacent to the second air outlet 12, and the first fan 8 and the second fan 9 work independently.

For example, in the example of fig. 1 and 2, the intake vent may be formed at the top of the cabinet 1, and the first and second outlet vents 11 and 12 may be provided at the lower portion of the cabinet 1 and spaced apart from each other along the length direction of the cabinet 1. The first heat exchanger 6 and the second heat exchanger 7, and the first fan 8 and the second fan 9 are arranged at intervals along the length direction of the machine shell 1, and are respectively opposite to the first air outlet 11 and the second air outlet 12.

When the indoor unit 100 of the air conditioner, such as a wall-mounted indoor unit of the air conditioner, is operated, at least one of the first fan 8 and the second fan 9 rotates to drive indoor air to flow, so that the indoor air can enter the first outlet channel 41 or the second outlet channel 51 of the casing 1 through the air inlet and exchange heat with the first heat exchanger 6 or the second heat exchanger 7 in the casing 1, and the air after heat exchange can be blown into the room through the first outlet 11 or the second outlet 12 to adjust the indoor temperature.

Since the first heat exchanger 6 and the second heat exchanger 7 are operated independently of each other, the first fan 8 and the second fan 9 are also operated independently of each other. Specifically, for example, when the user is located within the air supply range of the first air outlet 11, only the first heat exchanger 6 and the first fan 8 may operate, at this time, only the first air outlet 11 may be opened, and the air flow after heat exchange may be blown into the room after being guided by the first air outlet 11 and the two first air deflectors 2, so as to quickly adjust the temperature of the area corresponding to the first air outlet 11 in the room. The flowing direction of the airflow blown out from the first air outlet 11 can be adjusted through the two first air deflectors 2, so that the flowing direction of the airflow is matched with the working mode of the indoor unit 100 of the air conditioner, and the user experience is improved.

Or, when the user is located within the air supply range of the first air outlet 11, only the second heat exchanger 7 and the second fan 9 may work, at this time, only the second air outlet 12 may be opened, the air flow after heat exchange may be blown into the room after being guided by the second air outlet 12 and the two second air deflectors 3, wherein the flow direction of the air flow blown out from the second air outlet 12 may be adjusted by the two second air deflectors 3, so that the air flow may be prevented from blowing directly to the user.

Similarly, when a user is located in the air supply range of the second air outlet 12, only the second heat exchanger 7 and the second fan 9 may work, at this time, only the second air outlet 12 may be opened, and the air flow after heat exchange may be blown into the room after being guided by the second air outlet 12 and the two second air deflectors 3; or, only the first heat exchanger 6 and the first fan 8 may work, at this time, only the first air outlet 11 may be opened, and the air flow after heat exchange may be blown to the indoor through the first air outlet 11 and the flow guides of the two first air deflectors 2.

When a plurality of users are dispersed at each indoor position or the users dynamically move indoors, the first heat exchanger 6 and the second heat exchanger 7 can work simultaneously, the first fan 8 and the second fan 9 work simultaneously, the first air outlet 11 and the second air outlet 12 are opened simultaneously at the moment, air after heat exchange flows to the indoor space after being guided by the first air outlet 11, the second air outlet 12 and the two first air deflectors 2 and the two second air deflectors 3, the heat exchange efficiency of the indoor unit 100 of the air conditioner can be effectively improved, and therefore the indoor temperature can be quickly adjusted.

Therefore, the flow directions of the air flows at the first air outlet 11 and the second air outlet 12 are adjusted by the flow guiding effects of the two first air deflectors 2 and the two second air deflectors 3, and compared with a traditional air conditioner indoor unit, the flow directions of the air flows at the first air outlet 11 and the second air outlet 12 are more diversified, so that the air conditioner indoor unit 100 can well adjust the flow direction of the air flow at the first air outlet 11 or the second air outlet 12 according to the working mode. In addition, because the first heat exchanger 6 and the second heat exchanger 7 work independently, and the two first air deflectors 2 and the two second air deflectors 3 can adjust the flowing directions of the air flows of the first air outlet 11 and the second air outlet 12, the operation modes of the air conditioner indoor unit 100 can be effectively increased, so that different requirements of different users can be better met, and the user experience is improved.

It will be appreciated that since the first heat exchanger 6 and the second heat exchanger 7 operate independently of each other, it is also possible to control the temperatures of the first heat exchanger 6 and the second heat exchanger 7 to be the same or different when the first heat exchanger 6 and the second heat exchanger 7 operate simultaneously. When the temperatures of the first heat exchanger 6 and the second heat exchanger 7 are different, the air flow blown out from the first air outlet 11 and the air flow blown out from the second air outlet 12 have different temperatures, and two air flows with different temperatures can enable different indoor areas to have different temperatures, so that the indoor unit 100 of the air conditioner can control the temperature of indoor partitions, the requirements of users in different indoor areas can be met, and the user experience is improved. When the temperatures of the first heat exchanger 6 and the second heat exchanger 7 are the same, the temperature of the airflow at the first air outlet 11 is approximately the same as that of the airflow at the second air outlet 12, and the uniformity of the indoor temperature can be effectively guaranteed.

The second air sweeping assemblies 20 are arranged in the second air outlet channel 51, each second air sweeping assembly 20 comprises a second driving motor 201, a second swing arm 202, a second connecting rod 203 and a plurality of second air sweeping blades 204, the second driving motor 201 is fixed on the second air duct assembly 5, and when the second driving motor 201 works, the second driving motor 201 drives the second swing arm 202 to swing to drive the second connecting rod 203 to move left and right so as to drive the plurality of second air sweeping blades 204 on the second connecting rod 203 to swing left and right. As shown in fig. 1, 2, 6 and 8, a plurality of second wind sweeping blades 204 are spaced apart from each other along a length direction of a second link 203, a second swing arm 202 is connected to one end of the second link 203 in the length direction, and a second driving motor 201 is connected to the second swing arm 202. When the air flow at the second air outlet 12 needs to be swept from left to right, the second driving motor 201 rotates to drive the second swing arm 202 to swing, so that the swinging second swing arm 202 can drive the second connecting rod 203 to move from left to right to make the plurality of second air sweeping blades 204 on the second connecting rod 203 swing from left to right, thereby realizing that the second air sweeping blades 204 sweep from left to right, the air supply range of the air flow at the second air outlet 12 in the left-right direction can be effectively increased, and the second air sweeping assembly 20 is simple in structure and easy to install, and can further improve the assembly efficiency of the air conditioner indoor unit 100.

From this, the operation mode of air conditioner indoor unit 100 has been increased effectively, and the flow direction of the air current of first air outlet 11 and second air outlet 12 has more the variety, thereby air conditioner indoor unit 100 can adjust the flow direction of the air current of first air outlet 11 and second air outlet 12 well according to its mode, user experience has been promoted, and simultaneously, can increase the air supply scope of air conditioner indoor unit 100 on the left right direction, and first wind subassembly 10 and second wind subassembly 20 that sweeps is simple in structure, easily installation, can improve air conditioner indoor unit 100's assembly efficiency.

According to some embodiments of the present invention, the air conditioner indoor unit 100 includes a first air outlet mode and a second air outlet mode, and when the air conditioner indoor unit 100 is in the first air outlet mode, the two first air deflectors 2 extend substantially along the horizontal direction, and/or the two second air deflectors 3 extend substantially along the horizontal direction. Wherein, the two first wind deflectors 2 and the two second wind deflectors 3 can both extend along the horizontal direction (as shown in fig. 4); alternatively, only two first air deflectors 2 may extend substantially in the horizontal direction (not shown); still alternatively, only two second wind deflectors 3 may extend in a substantially horizontal direction (not shown).
