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.

For example, in the example of fig. 1, the air inlet may be formed at the top of the cabinet 1. Two air outlets, namely a first air outlet 11 and a second air outlet 12, are formed on the machine shell 1, and the first air outlet 11 and the second air outlet 12 can be spaced apart from each other along the length direction of the machine shell 1. Correspondingly, the number of the air duct assemblies 2, the number of the heat exchangers 4 and the number of the fans 3 are two, the number of the air duct assemblies 2 is the first air duct assembly 21 and the second air duct assembly 22, the number of the heat exchangers is the first heat exchanger 41 and the second heat exchanger 42, the number of the fans 3 is the first fan 31 and the second fan 32, and the first air duct assembly 21 and the second air duct assembly 22, the first heat exchanger 41 and the second heat exchanger 42, and the first fan 31 and the second fan 32 are all arranged along the length direction of the casing 1 at intervals.

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 31 and the second fan 32 rotates to drive the indoor air to flow, so that the indoor air can enter the first outlet channel 211 and/or the second outlet channel 221 of the casing 1 through the inlet and exchange heat with the first heat exchanger 41 or the second heat exchanger 42 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.

The refrigerant control device 7 is arranged between the first heat exchanger 41 and the second heat exchanger 42, the refrigerant control device 7 comprises a first refrigerant port 71, a second refrigerant port 72 and a third refrigerant port 73, the first refrigerant port 71 is communicated with the second indoor connector pipe 6, the second indoor connector pipe 6 is positioned between the first heat exchanger 41 and the second heat exchanger 42, the second refrigerant port 72 is connected with a first refrigerant liquid pipe 411, the third refrigerant port 73 is connected with a second refrigerant liquid pipe 421, and the first refrigerant port 71 is communicated with at least one of the second refrigerant port 72 and the third refrigerant port 73 in a switchable manner.

When the indoor unit 100 of the air conditioner, for example, a wall-mounted indoor unit of the air conditioner, is operated and a user is located on either the left side or the right side of the indoor unit 100 of the air conditioner, the first refrigerant port 71 may be switched to be communicated with only one of the second refrigerant port 72 and the third refrigerant port 73, at this time, only one of the corresponding first heat exchanger 41 and the corresponding second heat exchanger 42 may be operated, the fan 3 opposite to the operated heat exchanger 4 is operated, and the air outlet opposite to the operated heat exchanger 4 is opened. The working heat exchanger 4 may be the heat exchanger 4 corresponding to the area where the user is located, for example, the air conditioner 100 is in a cooling mode, and when the user is located on the left side of the air conditioner 100, the first refrigerant port 71 may only be communicated with the second refrigerant port 72, the refrigerant in the second indoor online pipe 6 connected to the outdoor unit (not shown) of the air conditioner may flow into the first heat exchanger 41 through the first refrigerant port 71, the second refrigerant port 72 and the first refrigerant pipe 411, and exchange heat with the air near the first heat exchanger 41, and the air after heat exchange is blown into the room through the first air outlet 11 under the action of the first fan 31, so that the temperature of the area where the user is located may be rapidly adjusted, and the energy consumption of the air conditioner 100 may be reduced. The refrigerant heat-exchanged in the first heat exchanger 41 flows to the outdoor unit of the air conditioner through the first refrigerant pipe 412 and the first indoor coupling pipe 5.

Of course, the working heat exchanger 4 may also be the heat exchanger 4 on the opposite side of the area where the user is located, for example, when the air conditioner 100 is in the cooling mode and the user is located on the left side of the air conditioner 100, the first refrigerant port 71 may only be communicated with the third refrigerant port 73, the refrigerant in the second indoor online pipe 6 connected to the air conditioner outdoor unit may flow into the second heat exchanger 42 through the first refrigerant port 71, the third refrigerant port 73 and the second refrigerant pipe 421, and exchange heat with the air near the second heat exchanger 42, and the air after heat exchange is blown into the room through the second air outlet 12 under the action of the second fan 32, so that the air flow can be prevented from directly blowing the user.

It is understood that the specific operation states of the first heat exchanger 41 and the second heat exchanger 42 can be specifically set according to the actual needs of users to better meet the actual application.

Thus, the refrigerant control device 7 is provided to split the refrigerant, so that the refrigerant flowing from the same first refrigerant port 71 can flow into the first heat exchanger 41 and the second heat exchanger 42 through the second refrigerant port 72 and the third refrigerant port 73, respectively, to thereby realize the operation of the first heat exchanger 41 and the second heat exchanger 42. Moreover, at least one of the first heat exchanger 41 and the second heat exchanger 42 can be controlled to work by controlling the communication and the separation of the first refrigerant port 71, the second refrigerant port 72 and the third refrigerant port 73, and the first heat exchanger 41 and the second heat exchanger 42 can work independently, so that the air outlet mode of the indoor unit 100 of the air conditioner can be increased, and the user experience is improved.

In addition, the arrangement of the first indoor coupling pipe 5, the refrigerant control device 7 and the second indoor coupling pipe 6 makes the distances between the refrigerant control device 7 and the first heat exchanger 41 and between the refrigerant control device 7 and the second heat exchanger 42 smaller, so that the second refrigerant port 72 and the first refrigerant liquid pipe 411, and the third refrigerant port 73 and the second refrigerant liquid pipe 421 are conveniently connected.

Two air duct assemblies 2, two heat exchangers 4 and two fans 3 are shown in fig. 1 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 2, heat exchangers 4 and fans 3, and the utility model also falls into the protection scope of the present invention.

The air conditioner indoor unit 100 according to an embodiment of the present invention, for example, a wall-mounted air conditioner indoor unit, is configured by disposing the first indoor link pipe 5, the refrigerant control device 7, and the second indoor link pipe 6 between the first heat exchanger 41 and the second heat exchanger 42. Therefore, the space between the first heat exchanger 41 and the second heat exchanger 42 is fully utilized, so that the volume of the air conditioner indoor unit 100 can be effectively reduced, the layout of other components in the machine shell 1 is facilitated, the structure of the whole air conditioner indoor unit 100 is more compact and the layout is more reasonable, and the connection of the second refrigerant port 72 and the first refrigerant liquid pipe 411, the third refrigerant port 73 and the second refrigerant liquid pipe 421 is facilitated.

According to some embodiments of the present invention, an escape opening 23 is defined between the first air duct assembly 21 and the second air duct assembly 22, and the first indoor inline pipe 5 and the second indoor inline pipe 6 pass through the escape opening 23. As shown in fig. 2, a first opening is formed at a side of the first air duct assembly 21 adjacent to the second air duct assembly 22, a second opening is formed at a side of the second air duct assembly 22 adjacent to the first air duct assembly 21, and the first opening and the second opening together form an avoiding opening 23.

In some alternative embodiments, referring to fig. 1, 2, 4 and 5, the first refrigerant port 71, the second refrigerant port 72 and the third refrigerant port 73 are formed at the bottom of the refrigerant control device 7. An escape opening 23 is formed between the tops of the first air duct assembly 21 and the second air duct assembly 22. Because the first fan 31 and the second fan 32 are arranged below the refrigerant control device 7, the avoidance port 23 is arranged between the tops of the first air duct assembly 21 and the second air duct assembly 22, so that the interference between the first indoor connecting pipe 5 and the second indoor connecting pipe 6 and the interference between the first fan 31 and the second fan 32 can be avoided, the arrangement of the first indoor connecting pipe 5 and the second indoor connecting pipe 6 is facilitated, the first refrigerant port 71, the second refrigerant port 72 and the third refrigerant port 73 are arranged at the bottom of the refrigerant control device 7, the interference between the first refrigerant liquid pipe 411 and the second refrigerant liquid pipe 421 and the interference between the first indoor connecting pipe 5 and the second indoor connecting pipe 6 can be avoided, and the arrangement of each pipeline can be more reasonable.

Further, as shown in fig. 2, the first indoor inline pipe 5 and the second indoor inline pipe 6 pass through the escape opening 23 and then extend downward to be adjacent to the bottom walls of the first air duct assembly 21 and the second air duct assembly 22, and then extend horizontally. Thereby, the space between the bottom wall of the air duct assembly 2 and the cabinet 1 can be effectively utilized, so that the layout of the indoor unit 100 of the air conditioner is more compact.

In some alternative embodiments, referring to fig. 2-6, the cross-sectional area of the first indoor inline pipe 5 is larger than the cross-sectional area of the second indoor inline pipe 6. When the indoor unit 100 of the air conditioner is in the cooling mode, the refrigerant in the first indoor coupling is a low-temperature low-pressure gaseous refrigerant, the low-temperature low-pressure gaseous refrigerant is converted into a low-temperature low-pressure liquid refrigerant by compression of the compressor, heat exchange of a heat exchanger of the outdoor unit of the air conditioner, and a throttling decompression function of a throttling device such as a capillary tube, and the low-temperature low-pressure liquid refrigerant is discharged to the second indoor coupling 6. The pressure of the gaseous refrigerant sucked by the compressor is lower than that of the discharged gaseous refrigerant, the pressure drop of the refrigerant in the compressor can be relieved due to the large cross-sectional area of the first indoor connecting pipe 5, and in order to maintain the refrigerant quantity of the second indoor connecting pipe 6, the large cross-sectional area of the first indoor connecting pipe 5 can maintain larger air inflow. In addition, the flow resistance of the gaseous refrigerant is different from the flow resistance of the liquid refrigerant, so that the cross-sectional area of the second indoor pipe 6 can be set to be smaller under the condition that the flow rates of the refrigerant in the first indoor pipe 5 and the second indoor pipe 6 are constant.

According to some embodiments of the present invention, the first heat exchanger 41 and the second heat exchanger 42 are connected by a connecting assembly 8, the connecting assembly 8 includes a first connecting member 81 and a second connecting member 82, the first connecting member 81 and the second connecting member 82 are both connected between the first heat exchanger 41 and the second heat exchanger 42, and the refrigerant control device 7 is located between the first connecting member 81 and the second connecting member 82. For example, in the examples of fig. 1, 5 and 6, one end of the first heat exchanger 41 adjacent to the second heat exchanger 42 is provided with a first heat exchange end plate 413, one end of the second heat exchanger 42 adjacent to the first heat exchanger 41 is provided with a second heat exchange end plate 423, the first connecting member 81 may be located on one side of the first heat exchanger 41 and the second heat exchanger 42 adjacent to the fan 3, two ends of the first connecting member 81 are respectively connected to the first heat exchange end plate 413 and the second heat exchange end plate 423, the second connecting member 82 may be located on one side of the first heat exchanger 41 and the second heat exchanger 42 away from the fan 3, and two ends of the second connecting member 82 are respectively connected to the first heat exchange end plate 413 and the second heat exchange end plate 423, so that the relative positions of the first heat exchanger 41 and the second heat exchanger 42 may be ensured to be stable. The first connecting member 81 and the second connecting member 82 may jointly define an accommodating space, and the refrigerant control device 7 may be located in the accommodating space. Therefore, the accommodating space between the first connecting piece 81 and the second connecting piece 82 is fully utilized, the compact structure of the air conditioner indoor unit 100 is ensured, and the first connecting piece 81 and the second connecting piece 82 can limit the movement of the refrigerant control device 7 in the front and back directions, so that the stability of the position of the refrigerant control device 7 is ensured.

Further, the first fan 31 includes a first motor 311 and a first wind wheel 312, the second fan 32 includes a second motor 321 and a second wind wheel 322, the first motor 311 and the second motor 321 are located between the first wind wheel 312 and the second wind wheel 322, the first connecting member 81 is connected to both the first air duct assembly 21 and the second air duct assembly 22, and the first motor 311 and the second motor 321 are respectively pressed on the first air duct assembly 21 and the second air duct assembly 22. As shown in fig. 1, 3 and 4, the first motor 311 is connected to the right side of the first wind rotor 312, and the second motor 321 is connected to the left side of the second wind rotor 322. A plurality of mounting holes are formed on both sides of the first connector 81 in the width direction, respectively. During installation, the first connecting member 81 may be placed on the first motor 311 and the second motor 321, and then, a plurality of threaded fasteners, such as screws, may pass through the plurality of mounting holes of the first connecting member 81, respectively, to fix the first connecting member 81 on the first air duct assembly 21 and the second air duct assembly, at this time, the first motor 311 may be compressed between the first connecting member 81 and the first air duct assembly 21, and the second motor 321 may be compressed between the first connecting member 81 and the second air duct assembly 22, thereby effectively ensuring the stability of the positions of the first motor 311 and the second motor 321, simplifying the mounting manner of the first motor 311 and the second motor 321, and improving the assembly efficiency of the indoor unit 100 of an air conditioner.

Optionally, an end of the first heat exchanger 41 away from the second heat exchanger 42 is fixedly connected to the first air duct assembly 21, and an end of the second heat exchanger 42 away from the first heat exchanger 41 is fixedly connected to the second air duct assembly 22. With such an arrangement, the first heat exchanger 41 can be more stably fixed on the first air duct assembly 21, and the second heat exchanger 42 can be more stably fixed on the second air duct assembly 22, so that the positions of the first heat exchanger 41 and the second heat exchanger 42 are further ensured to be stable.

According to some embodiments of the present invention, the refrigerant control device 7 may include a three-way valve 74, and the three-way valve 74 includes a first refrigerant port 71, a second refrigerant port 72, and a third refrigerant port 73. The number of the second refrigerant ports 72 and the third refrigerant ports 73 may be one, so that the three-way valve 74 may have a simpler structure and may be conveniently disposed.

Optionally, the number of the first refrigerant gas pipes 412 and the number of the second refrigerant gas pipes 422 may also be multiple, and the multiple first refrigerant gas pipes 412 and the multiple second refrigerant gas pipes 422 may be connected to the first indoor pipe joining machine 5, so that the heat exchange processes of the first heat exchanger 41 and the second heat exchanger 42 may be reduced, and the heat exchange effects of the first heat exchanger 41 and the second heat exchanger 42 may be enhanced.

Thus, by providing the refrigerant control device 7 with the three-way valve 74, the blowing temperatures of the first outlet 11 and the second outlet 12 can be controlled by controlling the amounts of the refrigerant flowing from the first refrigerant port 71 into the second refrigerant port 72 and the third refrigerant port 73, so that the temperatures of the air flows blown out from the first outlet 11 and the second outlet 12 can be the same or different. When the air flows of the first air outlet 11 and the second air outlet 12 have different temperatures, the two air flows with different temperatures can make different indoor areas have different temperatures, so that the indoor unit 100 of the air conditioner can control the indoor temperature in different zones, and the requirements of users in different indoor areas can be met. When the temperatures of the air flows of the first air outlet 11 and the second air outlet 12 are approximately the same, the uniformity of the indoor temperature can be effectively ensured.

Of course, the present invention is not limited thereto, and according to other embodiments of the present invention, the refrigerant control device 7 may further include a three-way pipe (not shown) including a first refrigerant port 71, a second refrigerant port 72 and a third refrigerant port 73, a first electronic expansion valve (not shown) provided on a pipeline of the three-way pipe communicating with the second refrigerant port 72, and a second electronic expansion valve (not shown) provided on a pipeline of the three-way pipe communicating with the third refrigerant port 73. Therefore, by arranging the three-way pipe, the first electronic expansion valve and the second electronic expansion valve, the first electronic expansion valve can control the on-off of the second refrigerant port 72, and the second electronic expansion valve can control the on-off of the third refrigerant port 73, so that a user can control the first heat exchanger 41 and/or the second heat exchanger 42 to exchange heat according to the requirement. Moreover, the first electronic expansion valve and the second electronic expansion valve can control the amount of the refrigerant flowing into the first heat exchanger 41 and the second heat exchanger 42, and also can make the first heat exchanger 41 and the second heat exchanger 42 have different heat exchange effects, so that the indoor unit 100 of the air conditioner can control the temperature of indoor areas, and user experience is improved.

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