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 4. 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 4, an air conditioner indoor unit 100 according to an embodiment of the present invention includes a casing 1, at least two air duct assemblies, at least two heat exchangers, and at least two fans.

Specifically, an air inlet and at least two air outlets are formed on the casing 1, the at least two air outlets include at least one first air outlet 11 and at least one second air outlet 12, a detection device 13 is arranged on the casing 1, and the detection device 13 is used for detecting a movement signal of a human body, so that the air conditioner indoor unit 100 adjusts an operation mode of the air conditioner indoor unit 100 according to the movement signal.

At least two wind channel subassemblies are all established in casing 1, and at least two wind channel subassemblies include at least one first wind channel subassembly 2 and at least one second wind channel subassembly 3, and first wind channel subassembly 2 has first air-out passageway 21, and first air-out passageway 21 communicates with first air outlet 11, and second wind channel subassembly 3 has second air-out passageway 31, and second air-out passageway 31 communicates with second air outlet 12. The at least two heat exchangers include at least one first heat exchanger 4 and at least one second heat exchanger 5, the first heat exchanger 4 is arranged between the air inlet and the first air duct assembly 2, the second heat exchanger 5 is arranged between the air inlet and the second air duct assembly 3, and the first heat exchanger 4 and the second heat exchanger 5 work independently. The at least two fans comprise at least one first fan 6 and at least one second fan 7, the first fan 6 comprises a first wind wheel 61, the first wind wheel 61 is arranged in the first air duct assembly 2, the second fan 7 comprises a second wind wheel 71, the second wind wheel 71 is arranged in the second air duct assembly 3, and the first fan 6 and the second fan 7 work independently.

For example, in the example of fig. 2, the air inlet may be formed at the top of the cabinet 1. The casing 1 is formed with two air outlets, which are a first air outlet 11 and a second air outlet 12, respectively, and the first air outlet 11 and the second air outlet 12 are spaced apart from each other along the length direction of the casing 1. Correspondingly, the number of the air duct assemblies, the number of the heat exchangers and the number of the fans are two, the two air duct assemblies are respectively a first air duct assembly 2 and a second air duct assembly 3, the first air duct assembly 2 and the second air duct assembly 3 are arranged at intervals along the length direction of the shell 1, the two heat exchangers are respectively a first heat exchanger 4 and a second heat exchanger 5, the first heat exchanger 4 and the second heat exchanger 5 are arranged at intervals along the length direction of the shell 1, the two fans are respectively a first fan 6 and a second fan 7, and the first fan 6 and the second fan 7 are arranged at intervals along the length direction of the shell 1. 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 wind wheel 61 of the first fan 6 and the second wind wheel 71 of the second fan 7 rotates to drive indoor air to flow, so that the indoor air can enter the first outlet channel 21 and/or the second outlet channel 31 of the casing 1 through the air inlet and exchange heat with the first heat exchanger 4 or the second heat exchanger 5 in the casing 1, and the air after heat exchange can be blown into the room through the first air outlet 11 or the second air outlet 12 to adjust the indoor temperature.

Since the air conditioner indoor unit 100 can adjust the operation mode of the air conditioner indoor unit 100 according to the human body movement signal detected by the detection device 13, the first heat exchanger 4 and the second heat exchanger 5 work independently of each other, and the first fan 6 and the second fan 7 work independently of each other. Specifically, for example, when the detection device 13 determines that a person is located within the air supply range of the first air outlet 11 according to the detected movement signal of the human body, only the first heat exchanger 4 and the first fan 6 may operate, at this time, only the first air outlet 11 may be opened, and the air flow after heat exchange may be blown from the first air outlet 11 to the room through the first air outlet channel 21 to adjust the temperature of the left area in the room; or, only the second heat exchanger 5 and the second fan 7 may work, at this time, only the second air outlet 12 may be opened, and the air flow after heat exchange may be blown from the second air outlet 12 to the indoor through the second air outlet channel 31, so that the air flow may be prevented from blowing directly to the user.

Similarly, when the detection device 13 determines that the person is located within the air supply range of the second air outlet 12 according to the detected human body activity signal, only the second heat exchanger 5 and the second fan 7 may work, at this time, only the second air outlet 12 may be opened, and the air flow after heat exchange may be blown from the second air outlet 12 to the indoor space through the second air outlet channel 31, so as to adjust the temperature of the indoor right area; or, only the first heat exchanger 4 and the first fan 6 may work, at this time, only the first air outlet 11 may be opened, and the air flow after heat exchange may be blown from the first air outlet 11 to the indoor through the first air outlet channel 21, so that the air flow may be prevented from blowing directly to the user.

When the detection device 13 judges that the human body is fixedly dispersed at each indoor position or the human body dynamically moves indoors according to the detected human body movement signal, the first heat exchanger 4 and the second heat exchanger 5 can work simultaneously, the first fan 6 and the second fan 7 work simultaneously, the first air outlet 11 and the second air outlet 12 are opened simultaneously at the moment, the air flow after heat exchange is blown indoors from the first air outlet 11 and the second air outlet 12 through the first air outlet channel 21 and the second air outlet channel 31 respectively, the heat exchange efficiency of the indoor unit 100 of the air conditioner can be effectively improved, and the indoor temperature can be quickly adjusted. When the detecting device 13 determines that the person is dynamically moving indoors according to the detected human body movement signal, the air sweeping assemblies in the first air outlet channel 21 and the second air outlet channel 31 can swing in the left-right direction, so that the direction of the airflow blown out from the first air outlet 11 or the second air outlet 12 can change dynamically along with the user. When the detection device 13 does not detect the activity signal, the air conditioner indoor unit 100 may operate in a low frequency energy saving mode to reduce energy consumption.

Therefore, the operation modes of the air conditioner indoor unit 100 are effectively increased, so that different requirements of different users can be better met, and the energy consumption of the air conditioner indoor unit 100 can be effectively reduced.

In addition, since the first heat exchanger 4 and the second heat exchanger 5 operate independently of each other, when the first heat exchanger 4 and the second heat exchanger 5 operate simultaneously, it is also possible to control the temperatures of the first heat exchanger 4 and the second heat exchanger 5 to be the same or different. When the temperatures of the first heat exchanger 4 and the second heat exchanger 5 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 4 and the second heat exchanger 5 are the same, the temperature of the airflow at the first air outlet 11 is approximately the same as the temperature of the airflow at the second air outlet 12, and the uniformity of the indoor temperature can be effectively guaranteed.

Two air duct assemblies, two heat exchangers and two fans are shown in fig. 2 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solution of the present application that the solution can be applied to other numbers of air duct assemblies, heat exchangers and fans, and the solution also falls within the protection scope of the present invention.

According to the utility model discloses air conditioner indoor unit 100, through set up two at least air outlets and detection device 13 on casing 1, and first heat exchanger 4 and second heat exchanger 5 independent work each other, first fan 6 and second fan 7 independent work each other. Therefore, compared with the traditional air conditioner indoor unit, the operation mode of the air conditioner indoor unit 100 is effectively increased, indoor zone air supply and zone temperature control of the air conditioner indoor unit 100 can be realized, different requirements of users can be met, and user experience is improved.

According to some embodiments of the present invention, referring to fig. 1-3, the detection device 13 is located between the first air outlet 11 and the second air outlet 12. So set up, can guarantee effectively that detection device 13 can detect the human activity signal in the air supply scope that first air outlet 11 covered and the human activity signal in the air supply scope that second air outlet 12 covered to make air conditioner indoor unit 100 can adjust air conditioner indoor unit 100's operating mode to human activity signal, in order to satisfy different users' demand.

According to some embodiments of the present invention, a mounting groove 14 is formed on the casing 1, and the detecting device 13 is rotatably disposed in the mounting groove 14. For example, in the example of fig. 1 to 4, the mounting groove 14 may be formed in the middle of the cabinet 1, and the detection device 13 may be entirely located in the mounting groove 14, in which case a side of the mounting groove 14 away from the center of the cabinet 1 protrudes from a side of the detection device 13 away from the center of the cabinet 1. Therefore, the mounting groove 14 can protect the detection device 13, the detection device 13 can be effectively prevented from being damaged, and dust is not easy to fall on the detection device 13. In addition, the range of the detection device 13 for detecting the activity signal of the human body can be effectively increased by rotatably arranging the detection device 13 in the mounting groove 14.

In some alternative embodiments, referring to fig. 3 in combination with fig. 4, the mounting groove 14 may be an elongated shape extending in the left-right direction, and the detection device 13 may be rotatable in the left-right direction. For example, the detection device 13 may be rotated 180 ° in the left-right direction. With this arrangement, the range of the detection device 13 for detecting the motion signal of the human body in the left-right direction can be effectively increased. The "left-right direction" refers to a left-right direction when the air conditioner indoor unit 100 is operating.

Further, the width of the mounting groove 14 in the left-right direction gradually increases from the inside to the outside. Here, it should be noted that the term "from inside to outside" refers to a direction from the center of the air conditioner indoor unit 100 toward the outside of the air conditioner indoor unit 100. As shown in fig. 4, the mounting groove 14 has a substantially trapezoidal shape in a longitudinal section, and the mounting groove 14 has a minimum width on a side adjacent to the center of the indoor unit 100 and a maximum width on a side away from the center of the indoor unit 100. Therefore, the detection device 13 can be reliably installed in the installation groove 14, and the detection device 13 can be ensured to have a larger detection range in the left-right direction.

In other alternative embodiments, the detection device 13 may also be rotated through 180 °. The detecting device 13 can rotate at least 4180 ° at the front side of the casing 1 to detect at least the activity signal of the human body at the front side of the detecting device 13. For example, the detection device 13 may be rotated 180 ° in the left-right direction. This can expand the detection range of the detection device 13 and improve the detection efficiency of the detection device 13.

Alternatively, the detection means 13 may comprise infrared detection means. The infrared detection device is used to realize intelligent human detection, for example, to detect the activity signal of a human body, and the air conditioner indoor unit 100 can adjust the operation mode of the air conditioner indoor unit 100 according to the actual requirement of the user by using the activity signal of the human body detected by the infrared detection device. Alternatively, the infrared detection device may be an infrared camera. But is not limited thereto.

According to some embodiments of the present invention, a controller (not shown) is disposed in the casing 1, the controller communicates with the detecting device 13, and the controller is configured to receive the activity signal and control the operation mode of the indoor unit 100 of the air conditioner according to the activity signal. For example, when the indoor unit 100 of the air conditioner works, the infrared detection device can detect the activity signal of the human body in the room first, and then send the activity signal to the controller, and the controller processes the activity signal according to the received activity signal, determines the operation mode of the indoor unit 100 of the air conditioner under the activity signal, and controls the operation of the indoor unit 100 of the air conditioner under the operation mode, so that the intelligence of the indoor unit 100 of the air conditioner can be improved, and the user experience is further improved.

According to some embodiments of the utility model, interval setting about first air outlet 11 and the second air outlet 12, the central axis of first air outlet 11 and second air outlet 12 from inside to outside, along the length direction orientation of casing 1 slope the extension of the direction of keeping away from casing 1 center. Referring to fig. 2 and 3, the central axis of the first air outlet 11 may extend obliquely from inside to outside to the left, and the central axis of the second air outlet 12 may extend obliquely from inside to outside to the right. Therefore, the central axis of the first outlet 11 and the central axis of the second outlet 12 are set to extend in different directions, so that the air supply range of the indoor unit 100 of the air conditioner in the left-right direction can be increased. Moreover, when the first air outlet 11 and the second air outlet 12 work cooperatively, the air supply range of the air conditioner indoor unit 100 in the left-right direction can be further expanded, and the user experience is improved.

Further, an included angle between projections of central axes of the first air outlet 11 and the second air outlet 12 on the rear surface of the cabinet 1 and a projection of a cross-section passing through a center of the cabinet 1 on the rear surface of the cabinet 1 is α, where α satisfies: alpha is less than 0 degree and less than or equal to 5 degrees. When alpha is greater than 5 °, an included angle between a projection of the central axis of the first air outlet 11 or the central axis of the second air outlet 12 on the rear surface of the cabinet 1 and a projection of a cross-section passing through the center of the cabinet 1 on the rear surface of the cabinet 1 is large, an included angle between the central axis of the first air outlet 11 and the central axis of the second air outlet 12 may be large, and a width of the cabinet 1 in the up-down direction may be increased, so that an installation space of the air conditioner indoor unit 100 is increased, and further, applicability of the air conditioner indoor unit 100 may be affected. Therefore, by making α satisfy 0 ° < α ≦ 5 °, the installation space of the air conditioner indoor unit 100 can be effectively ensured while the air supply range of the air outlet 11 is ensured to be expanded, and thus the applicability of the air conditioner indoor unit 100 can be ensured.

Optionally, a may further satisfy: α ═ 3 °. When α > 3 °, the width of the cabinet 1 may be large, which may increase the installation space of the air conditioner indoor unit 100; when α < 3 °, an angle between a projection of the central axis of the first air outlet 11 or the central axis of the second air outlet 12 on the rear surface of the cabinet 1 and a projection of a cross-section passing through the center of the cabinet 1 on the rear surface of the cabinet 1 is small, so that an air blowing range of the indoor unit 100 in the left-right direction is relatively reduced, and it may be inconvenient to machine the cabinet 1. Therefore, when α is 3 °, the installation space of the air conditioner indoor unit 100 can be ensured, the air supply range of the air conditioner indoor unit 100 in the left-right direction can be ensured, and the processing of the housing 1 is facilitated.

Other configurations and operations of the air conditioner indoor unit 100 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.
