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 indoor unit 100, i.e., the indoor unit, is connected to an outdoor unit, i.e., the outdoor unit (not shown), installed in an outdoor space, through a pipe. The outdoor unit of the air conditioner may be provided with a compressor, an outdoor heat exchanger, an outdoor fan, an expander, and the like of a refrigeration cycle, and the indoor unit 100 may be provided with an indoor heat exchanger and an indoor fan.
For example, the indoor unit may include a wall-mounted indoor unit installed on a wall of the indoor space.
As shown in fig. 1 to 3, an air conditioner indoor unit 100 according to an embodiment of the present invention includes a cabinet 1, a plurality of duct assemblies 2, a plurality of heat exchangers 3, and a plurality of fans 4. The heat exchanger 3 is the indoor heat exchanger, and the fan 4 is the indoor fan. In the description of the present invention, "a plurality" means two or more.
An air inlet and a plurality of air outlets 11 are formed on the machine case 1, the plurality of air outlets 11 are formed at the bottom of the machine case 1, and the plurality of air outlets 11 include a first air outlet 111 and a second air outlet 112 which are arranged left and right. The air duct assemblies 2 are all arranged in the machine shell 1, the air duct assemblies 2 comprise a first air duct assembly 21 and a second air duct assembly 22, the first air duct assembly 21 is provided with a first air outlet channel 211, the first air outlet channel 211 is communicated with a first air outlet 111, the second air duct assembly 22 is provided with a second air outlet channel 221, the second air outlet channel 221 is communicated with a second air outlet 112, the heat exchangers 3 comprise a first heat exchanger 31 and a second heat exchanger 32, the first heat exchanger 31 is arranged between an air inlet and the first air duct assembly 21, the second heat exchanger 32 is arranged between the air inlet and the second air duct assembly 22, the fans 4 comprise a first fan 41 and a second fan 42, the first fan 41 is arranged on the first air duct assembly 21, and the second fan 42 is arranged on the second air duct assembly 22.
For example, in the example of fig. 2 and 3, there are two air outlets 11, two air duct assemblies 2, two heat exchangers 3, and two fans 4, where the two air outlets 11 are the first air outlet 111 and the second air outlet 112, the two air duct assemblies 2 are the first air duct assembly 21 and the second air duct assembly 22, the two heat exchangers 3 are the first heat exchanger 31 and the second heat exchanger 32, and the two fans 4 are the first fan 41 and the second fan 42. Wherein the first fan 41 and the second fan 42 may be cross-flow fans. When the air conditioner is started, indoor air can flow into the casing 1 from the air inlet under the action of the first fan 41 and the second fan 42, and flows through the first heat exchanger 31 and the second heat exchanger 32 for heat exchange, the air after heat exchange can be sucked in along the radial direction of the fan 4, then is conveyed to the first air outlet 111 and the second air outlet 112, and finally flows out from the first air outlet 111 and the second air outlet 112, so that the indoor temperature can be adjusted.
Two air outlets 11, two air duct assemblies 2, two heat exchangers 3 and two fans 4 are shown in fig. 1-3 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 three or more air outlets 11, air duct assemblies 2, heat exchangers 3 and fans 4, and this also falls into the protection scope of the present invention.
Wherein the first heat exchanger 31 and the second heat exchanger 32 are operated independently of each other, and the first fan 41 and the second fan 42 are operated independently of each other. For example, in the example of fig. 2, 9 and 10, when indoor air flows into the cabinet 1 from the air inlet, a part of the air flow passes through the first heat exchanger 31 under the action of the first fan 41 to exchange heat, and the air after heat exchange can enter the first fan 41, then flow to the first air outlet 111 along the first air outlet channel 211, and finally flow into the indoor from the first air outlet 111; another part of the airflow passes through the second heat exchanger 32 for heat exchange under the action of the second fan 42, and the air after heat exchange can enter the second fan 42, then flow to the second air outlet 112 along the second air outlet channel 221, and finally flow into the room from the second air outlet 112.
Therefore, through the above arrangement, the first heat exchanger 31 and the second heat exchanger 32 can respectively and independently control the air supply temperature, the first fan 41 and the second fan 42 can respectively and independently control the air supply quantity, so that the temperature and the air quantity of the air flow blown out from the first air outlet 111 and the second air outlet 112 can be different, thereby realizing the zone air supply of the air conditioner indoor unit 100, realizing different heat exchange effects in different zones by using the same air conditioner indoor unit 100, meeting the requirements of different users in the same room, and effectively improving the use comfort of the users. Moreover, when one of the first outlet 111 and the second outlet 112 is closed, the single-side air supply of the air conditioner indoor unit 100 can be realized according to the user requirement.
The first air outlet 111 and the second air outlet 112 extend obliquely upward from the direction of the ends adjacent to each other toward the ends away from each other, the first heat exchanger 31 extends in the same direction as the first air outlet 111, and the second heat exchanger 32 extends in the same direction as the second air outlet 112. The first fan 41 and the first outlet 111 extend in the same direction, and the second fan 42 and the second outlet 112 extend in the same direction. For example, in the example of fig. 2, 3, 7 and 9, the first and second air duct assemblies 21 and 22 are generally V-shaped, the first and second air outlets 111 and 112 are generally V-shaped, the first and second heat exchangers 31 and 32 are generally V-shaped, and the first and second fans 41 and 42 are generally V-shaped.
Therefore, through the arrangement, the distances between the first heat exchanger 31 and the first fan 41, between the second heat exchanger 32 and the second fan 42, between the first fan 41 and the first air outlet 111, and between the second fan 42 and the second air outlet 112 can be more uniform, so that the temperature and the air volume of the air flow output by the first air outlet 111 and the second air outlet 112 can be more uniform, and the user experience can be further improved. Furthermore, the first outlet 111 and the second outlet 112 can guide the air flow, so that the air flow flowing out from the outlet 11 (for example, the first outlet 111) at the left end of the casing 1 can flow into the room obliquely leftwards relative to the cross section passing through the center of the casing 1, and the air flow flowing out from the outlet 11 (for example, the second outlet 112) at the right end of the casing 1 can flow into the room obliquely rightwards relative to the cross section passing through the center of the casing 1, so that the air flow can be diffused towards the left and right sides relative to the cross section passing through the center of the casing 1, the air supply angle of the indoor unit 100 of the air conditioner can be increased, and the air supply range of the indoor unit 100 can be expanded. In addition, when the air outlet temperatures and the air volumes of the first air outlet 111 and the second air outlet 112 are different, the first air outlet 111 and the second air outlet 112 arranged in this way can avoid mutual interference of air flows, so that the air flows with different temperatures flowing out of the first air outlet 111 and the second air outlet 112 can enable different indoor areas to have different temperatures, and the requirements of users in different areas on comfortable air temperatures can be better met.
The first heat exchanger 31 and the second heat exchanger 32 are connected by a connecting assembly 6. From this, the coupling assembling 6 that so sets up can realize being connected between first heat exchanger 31 and the second heat exchanger 32, has guaranteed the stability of the relative position of first heat exchanger 31 and second heat exchanger 32 effectively to can effectively guarantee the heat transfer effect. During installation, the connecting assembly 6 can connect the two independent heat exchangers 3 into a whole, and then integrally install the heat exchangers 3 on the air duct assembly 2, so that the assembling efficiency of the indoor unit 100 of the air conditioner can be improved.

Moreover, by arranging the first heat exchanger 31 and the second heat exchanger 32 which work independently of each other and the first fan 41 and the second fan 42 which work independently of each other, the temperature and the air volume of the air flow blown out from the first air outlet 111 and the second air outlet 112 can be different, so that different heat exchange effects can be realized in different areas by the same air conditioner indoor unit 100, different user requirements in the same scene are met, and the user experience can be effectively improved. In addition, the first heat exchanger 31 and the second heat exchanger 32 are connected through the connecting assembly 6, so that the stability of the relative positions of the two heat exchangers 3 is effectively ensured, and the assembly efficiency of the air conditioner indoor unit 100 can be effectively improved.
In some alternative embodiments of the present invention, referring to fig. 2 and 3, the included angle between the plane of the first air outlet 111 and the cross-section passing through the center of the casing 1 is α1The included angle between the plane of the second air outlet 112 and the cross section passing through the center of the casing 1 is α2Wherein α is1、α2Respectively satisfy: alpha is not less than 85 DEG1＜90°，85°≤α2< 90 deg. Specifically, for example, when α1Or alpha2When the angle is smaller than 85 °, an included angle between the plane where the first air outlet 111 or the second air outlet 112 is located and the cross section passing through the center of the housing 1 is too small, which may cause an excessively large inclination angle of the first air outlet 111 or the second air outlet 112 relative to the horizontal plane, on one hand, may cause an excessively large occupied space of the whole air conditioner indoor unit 100 and poor appearance aesthetic property; on the other hand, the spatial layout of the heat exchanger 3 and the fan 4 in the cabinet 1 is not facilitated. When alpha is1Or alpha2When the angle is larger than 90 °, the air supply angle of the first air outlet 111 or the second air outlet 112 is reduced, so as to reduce the air supply range of the indoor unit 100 of the air conditioner.
Thereby, by making alpha1、α2Satisfies the following conditions: alpha is not less than 85 DEG1Alpha is less than 90 degrees and less than or equal to 85 degrees2< 90 °, while ensuring that the first air outlet 111 and the second air outlet 112 can effectively enlarge the air supply range of the air conditioner indoor unit 100, the structural design of the air conditioner indoor unit 100 is more reasonable, the structural strength of the air conditioner indoor unit 100 can be improved, the occupied space of the air conditioner indoor unit 100 is reduced, the spatial layout of the heat exchanger 3 and the fan 4 in the casing 1 can be more reasonable, and the appearance attractiveness of the air conditioner indoor unit 100 can be effectively improved. Further optionally, α1、α2Can further satisfy: alpha is alpha1＝87°，α287 deg.. But is not limited thereto.
In some alternative embodiments of the present invention, in conjunction with fig. 4, the width of at least one of the first outlet port 111 and the second outlet port 112 in the left-right direction gradually increases from the inside to the outside. Here, it should be noted that the direction "in" is understood as a direction toward the center of the casing 1, and the opposite direction is defined as "out", i.e., a direction away from the center of the casing 1. For example, in the example of fig. 4, the first outlet 111 and the second outlet 112 may be formed in a horn-shaped structure, and the width of the outside of the outlet 11 is greater than the width of the inside of the outlet 11 along the length direction of the cabinet 1. Therefore, through the arrangement, the shielding of the outside of the air outlet 11 on the air flow can be reduced, so that the air supply range of the air conditioner indoor unit 100 can be further expanded, and the wide-area air supply of the air conditioner indoor unit 100 is realized.
In some alternative embodiments of the present invention, referring to fig. 2-4, the cabinet 1 is arranged in bilateral symmetry. For example, in the example of fig. 2-4, the first and second air outlets 111, 112, the first and second heat exchangers 31, 32, and the first and second fans 41, 42 are all symmetrical about a cross-section through the center of the enclosure 1. With such an arrangement, the inclination angle of the air flow flowing out from the first air outlet 111 relative to the cross section passing through the center of the machine case 1 may be equal to the inclination angle of the air flow flowing out from the second air outlet 112 relative to the cross section passing through the center of the machine case 1, so that the air outlet at the left and right sides of the whole air conditioner indoor unit 100 is more uniform, and the air flow may be uniformly diffused into the whole room. Moreover, the stress of the whole air conditioner indoor unit 100 can be more uniform, and the gravity center of the air conditioner indoor unit 100 is prevented from inclining left or right, so that the installation stability of the whole air conditioner indoor unit 100 can be ensured.

For example, in different operation modes, the first refrigerant port 51 may communicate with different refrigerant ports (i.e., the second refrigerant port 52 and the third refrigerant port 53). The first refrigerant port 51 may be communicated with only one of the second refrigerant port 52 and the third refrigerant port 53, and at this time, one of the corresponding first heat exchanger 31 and the corresponding second heat exchanger 32 operates; alternatively, the first refrigerant port 51 may communicate with the second refrigerant port 52 and the third refrigerant port 53 at the same time, and both the first heat exchanger 31 and the second heat exchanger 32 may operate at this time.
Accordingly, the refrigerant control device 5 can be provided to split the refrigerant, so that the refrigerant flowing from the first refrigerant port 51 can flow into the first heat exchanger 31 and the second heat exchanger 32 through the second refrigerant port 52 and the third refrigerant port 53 at the same time, thereby realizing the operation of the first heat exchanger 31 and the second heat exchanger 32. Moreover, the operation of different heat exchangers 3 can be controlled by controlling the communication and the separation of the first refrigerant port 51, the second refrigerant port 52 and the third refrigerant port 53, so that different heat exchangers 3 can be controlled to exchange heat according to the needs of users. In addition, the amount of refrigerant flowing from the first refrigerant port 51 into the second refrigerant port 52 and the third refrigerant port 53 can be controlled to control the air supply temperature of the first air outlet 111 and the second air outlet 112, so that the same air conditioner indoor unit 100 can achieve different air heat exchange effects, and different user requirements in the same scene can be fully met.
In some alternative embodiments of the present invention, as shown in fig. 2, 7 and 8, the refrigerant control device 5 may include a three-way valve including a first refrigerant port 51, a second refrigerant port 52 and a third refrigerant port 53.
