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 4.

As shown in fig. 1 and 2, an air conditioner according to some embodiments of the present application includes an air conditioner indoor unit 100 installed in an indoor space. 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 and 2, an air conditioner indoor unit 100 according to an embodiment of the present invention includes a cabinet 1, at least one heat exchanger 2, and at least one fan 3. The heat exchanger 2 is the indoor heat exchanger, and the fan 3 is the indoor fan.

Specifically, an air inlet and at least one air outlet 11 are formed on the casing 1, the air outlet 11 extends obliquely towards the direction of two ends along the middle part of the left and right direction of the casing 1, the direction of the air outlet 11 is close to the center of the casing 1, the heat exchanger 2 is arranged in the casing 1, and the fan 3 is arranged on one side of the heat exchanger 2 far away from the air inlet.

Here, it should be noted that "the middle portion in the left-right direction of the housing 1" should be broadly understood in the present application, and refers to a portion between the left end and the right end of the housing 1, and is not limited to the center in the left-right direction of the housing 1.

For example, in the example of fig. 1 and 2, the fan 3 may be a crossflow fan. When the air conditioner is started to operate, indoor air can flow into the machine shell 1 from the air inlet under the action of the fan 3 and flows through the heat exchanger 2 for heat exchange, and the air after heat exchange can be sucked in along the radial direction of the fan 3 and then is conveyed to the air outlet 11. The air flow from the outlet 11 at the left end of the cabinet 1 may flow into the room obliquely leftward with respect to the cross section passing through the center of the cabinet 1, and the air flow from the outlet 11 at the right end of the cabinet 1 may flow into the room obliquely rightward with respect to the cross section passing through the center of the cabinet 1. From this, through setting up foretell air outlet 11, air outlet 11 can lead the air current, makes the air current can be for the cross section orientation left and right sides diffusion at the center of casing 1 to can increase air conditioner 100's air supply angle, can effectively enlarge air conditioner 100's air supply scope, make the temperature value of whole room air can reach user's settlement temperature fast evenly, avoid local temperature to hang down excessively or too high, and then can effectively promote user experience.

According to the air conditioner indoor unit 100 of the embodiment of the invention, the air inlet and the at least one air outlet 11 are formed on the casing 1, the middle part along the left and right directions of the casing 1 extends towards the directions of the two ends, and the air outlet 11 extends towards the direction close to the center of the casing 1 in an inclined manner, so that the air outlet 11 can effectively increase the air supply angle, the air supply range of the air conditioner indoor unit 100 is expanded, and the use comfort of a user can be effectively improved.

In some alternative embodiments of the present invention, referring to fig. 1 to 3, an included angle between a plane where the air outlet 11 is located and a cross-section passing through the center of the housing 1 is α, where α satisfies: alpha is more than or equal to 85 degrees and less than 90 degrees. Specifically, for example, when α < 85 °, the included angle between the plane of the air outlet 11 and the cross section passing through the center of the housing 1 is too small, which may result in too large an inclination angle of the air outlet 11 relative to the horizontal plane, and on the one hand, may result in too large occupied space of the whole air conditioner indoor unit 100 and poor appearance aesthetic property; on the other hand, the space layout of the heat exchanger 2 and the fan 3 in the casing 1 is not facilitated. When the angle α is greater than 90 °, the air outlet 11 reduces the air supply angle, thereby reducing the air supply range of the indoor unit 100 of the air conditioner. Thus, by making α satisfy: alpha is more than or equal to 85 degrees and less than 90 degrees, when the air outlet 11 is ensured to 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 2 and the fan 3 in the shell 1 can be more reasonable, and the appearance attractiveness of the air conditioner indoor unit 100 can be effectively improved. Further optionally, α may further satisfy: α is 87 °. But is not limited thereto.

In some optional embodiments of the present invention, with reference to fig. 2 to 4, the number of the air outlets 11 may be multiple, the multiple air outlets 11 include at least one first air outlet 111 and at least one second air outlet 112, the first air outlet 111 and the second air outlet 112 are arranged at a left-right interval, and the first air outlet 111 and the second air outlet 112 respectively extend obliquely toward a direction approaching to the center of the enclosure 1 along a direction from a middle portion of the left-right direction of the enclosure 1 toward two ends. In the description of the present invention, "a plurality" means two or more.

For example, in the example of fig. 2 to 4, there are two air outlets 11, the two air outlets 11 are a first air outlet 111 and a second air outlet 112, the first air outlet 111 is located at the left side of the second air outlet 112, the central axis of the first air outlet 111 extends obliquely leftward from inside to outside with respect to the cross-section passing through the center of the cabinet 1, and the central axis of the second air outlet 112 extends obliquely rightward from inside to outside with respect to the cross-section passing through the center of the cabinet 1. Wherein, every air outlet 11 department can be equipped with interior aerofoil subassembly 6 and outer aerofoil subassembly 5, and outer aerofoil subassembly 5 can drive it through actuating mechanism 51 and open and close, and interior aerofoil subassembly 6 can drive it through aerofoil motor 61 and open and close to realize better horizontal wind-guiding effect. The external wind plate assembly 5 may shield the corresponding air outlet 11 to completely seal the air outlet 11, so as to prevent external dust or impurities such as insects from entering the air conditioner indoor unit 100 through the air outlet 11. When it is required to deliver airflow from the outlets 11, the driving mechanism 51 may drive the outer wind plate assembly 5 to adjust to a set angle, so as to expose the corresponding outlets 11.

When a user approaches the second outlet 112, the outer wind plate assembly 5 at the first outlet 111 can be opened and the outer wind plate assembly 5 at the second outlet 112 can be closed, so that the airflow can be only delivered into the room from the first outlet 111, and the airflow output from the second outlet 112 is prevented from directly blowing the user; when a user approaches the first outlet 111, the outer wind plate assembly 5 at the second outlet 112 may be opened and the outer wind plate assembly 5 at the first outlet 111 may be closed, so that the airflow can only be delivered to the room from the second outlet 112, so as to prevent the airflow output from the first outlet 111 from directly blowing the user; when the user is relatively far away from the first outlet 111 and the second outlet 112, the outer wind plate assembly 5 at the first outlet 111 and the outer wind plate assembly 5 at the second outlet 112 can be opened simultaneously, so that the air flow can be delivered from the first outlet 111 and the second outlet 112 to the indoor simultaneously. Of course, the first outlet 111 and the second outlet 112 may also be used for exhausting air toward the user according to the user's requirement, which is not limited in the present invention.

Therefore, by arranging the first air outlet 111 and the second air outlet 112, the opening and closing of the first air outlet 111 and the second air outlet 112 can be controlled through the requirements of a user, and the user experience is effectively improved. Moreover, when the first air outlet 111 and the second air outlet 112 simultaneously discharge air, the air supply angle of the air conditioner indoor unit 100 can be effectively increased, and the air supply range of the air conditioner indoor unit 100 is expanded.

Two outlets 11 are shown in fig. 1-4 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solutions of the present application that the solutions can be applied to three or more outlets 11, which also falls within the protection scope of the present invention.

Alternatively, as shown in fig. 2 to 4, the first outlet port 111 and the second outlet port 112 are arranged in bilateral symmetry. For example, in the example of fig. 2-4, the first outlet 111 and the second outlet 112 are symmetrical about a cross-section through the center of the cabinet 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.

Of course, the present invention is not limited thereto, and in other embodiments of the present invention, there may be one air outlet 11 (not shown), the air outlet 11 extends along the left-right direction, the left end of the air outlet 11 extends to the left end adjacent to the casing 1, and the right end of the air outlet 11 extends to the right end adjacent to the casing 1.

Here, it should be noted that "the left end of the air outlet 11 extends to be adjacent to the left end of the casing 1" may be understood as that the left end of the air outlet 11 is closer to the left end of the casing 1 than to the center of the casing 1 in the left-right direction, that is, the distance between the left end of the air outlet 11 and the left end of the casing 1 is smaller than the distance between the left end of the air outlet 11 and the center of the casing 1 in the left-right direction; the expression "the right end of the air outlet 11 extends to the right end adjacent to the casing 1" is understood to mean that the right end of the air outlet 11 is closer to the right end of the casing 1 than to the center of the casing 1 in the left-right direction, that is, the distance between the right end of the air outlet 11 and the right end of the casing 1 is smaller than the distance between the right end of the air outlet 11 and the center of the casing 1 in the left-right direction.

From this, through making the air outlet 11 be one, the processing of air outlet 11 is more convenient, can effectively improve air conditioner indoor unit 100's machining efficiency, and air outlet 11 department can only need set up a aviation baffle to can effectively reduce whole air conditioner indoor unit 100's spare part quantity, reduce cost. Moreover, because the air outlet 11 extends continuously in the left-right direction, the whole air outlet 11 can convey air flow to the indoor, and the air conditioner is ensured to have better refrigerating and heating effects. In addition, the left end and the right end of the air outlet 11 extend to the two ends of the adjacent casing 1 respectively, and the length of the air outlet 11 is large, so that the area of the air outlet 11 can be increased, the air supply range of the air conditioner indoor unit 100 is ensured to be enlarged, and the air output of the air conditioner indoor unit 100 can be effectively improved.

In some alternative embodiments of the present invention, as shown in fig. 2 and 3, the outlet 11 is formed at the bottom of the cabinet 1, and the bottom of the cabinet 1 is formed in a V shape. For example, in the example of fig. 2 and 3, the distance between the bottom of the cabinet 1 and the top surface of the cabinet 1 gradually decreases in the direction from the middle of the left-right direction of the cabinet 1 toward both ends. Therefore, because the indoor unit 100 of the air conditioner is usually installed on the upper part of the wall, the air outlet 11 is formed at the bottom of the casing 1, the air flow after heat exchange of the heat exchanger 2 can be better diffused downwards to the area where people are located, the indoor air temperature can reach the comfortable temperature of the human body more quickly, and the use comfort of the user can be effectively improved. Moreover, the bottom of the machine shell 1 is formed into a V shape, the air outlet 11 can better enlarge the air supply range, air flow after heat exchange of the heat exchanger 2 can be more uniformly conveyed to the whole indoor space, and the local temperature is prevented from being too high or too low.

In some embodiments of the present invention, referring to fig. 4, the width of the at least one outlet port 11 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 outlet 11 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 embodiments of the present invention, with reference to fig. 2 to 4, the number of the air outlets 11 is multiple, a plurality of air ducts independent from each other are defined in the casing 1, the plurality of air ducts correspond to the plurality of air outlets 11 one to one, and one end of each air duct is the air outlet 11. The heat exchangers 2 are multiple, the heat exchangers 2 correspond to the air ducts respectively, and the heat exchangers 2 work independently. The fans 3 are multiple, each fan 3 comprises a wind wheel 31, the wind wheels 31 are respectively arranged in the air ducts, and the fans 3 work independently.

For example, in the example of fig. 2-4, the air outlet 11, the air duct, the heat exchanger 2, and the fan 3 are all two, and the two air outlets 11, the two air ducts, the two heat exchangers 2, and the two fans 3 may all be symmetrical about a cross-section through the center of the cabinet 1. Wherein, two heat exchangers 2 can be connected in parallel through a three-way control valve 8. The wind turbine 3 may include a wind rotor 31 and a wind rotor motor 32, and the wind rotor motor 32 is used for driving the wind rotor 31 to rotate. Each air duct is internally provided with a fan 3, and each fan 3 is arranged on one side of the corresponding heat exchanger 2 adjacent to the air outlet 11. When the air conditioner is started, indoor air can flow into the machine shell 1 from the air inlet under the action of the fan 3 and flows through the heat exchanger 2 for heat exchange, the air after heat exchange can be sucked in along the radial direction of the fan 3, then flows to the air outlet 11 at one end of the air channel along the air channel, and finally flows into the indoor space from the air outlet 11. Therefore, by arranging the air ducts which are independent of each other, the heat exchangers 2 which work independently of each other and the fans 3 which work independently of each other, the temperature and the air volume of the air flow blown out from the different air outlets 11 can be different, so that the same air conditioner indoor unit 100 can output the air flow with different temperatures in different areas, and different user requirements in the same room are met.

Of course, the present invention is not limited to this, and in other alternative embodiments of the present invention, there are a plurality of air outlets 11, there may be one fan 3 and one heat exchanger 2, the heat exchanger 2 is opposite to the plurality of air outlets 11, and the fan 3 is located between the heat exchanger 2 and the plurality of air outlets 11. So set up, only need inject an wind channel in the casing 1, the structure of casing 1 inside can be simpler, and the installation of fan 3 and heat exchanger 2 is more convenient, can reduce air conditioner indoor unit 100's cost. Moreover, as the air outlets 11 are multiple, the opening and closing of different air outlets 11 can be controlled according to the requirements of users, so that the requirements of different users in the same room can be met, and the use comfort of the users is effectively improved.

In some embodiments of the present invention, as shown in fig. 1 to 4, the air conditioner indoor unit 100 may further include a detection device 4 and a controller. The detection device 4 is disposed on the casing 1, the detection device 4 is used for detecting a movement signal of a human body, the controller is in communication with the detection device 4, and the controller is used for receiving the movement signal of the human body and controlling an air outlet direction and/or an operation frequency of the indoor unit 100 of the air conditioner according to the movement signal of the human body. For example, the user can set the airflow output from the air outlet 11 to flow along with the human body or avoid the human body according to the requirement of the user. Therefore, by arranging the detection device 4, the flowing direction of the air flow can be controlled according to the requirements of users. Moreover, when the detection device 4 detects that no person is in the room, the air conditioner can perform an energy-saving mode of low-frequency operation, so that the energy consumption of the air conditioner can be effectively reduced.

Optionally, referring to fig. 2, the air conditioner indoor unit 100 further includes a base 9, at least one longitudinal wind plate assembly 91 and at least one electrical box 7. Wherein, the electrical box 7 can be arranged at the upper part of the heat exchanger 2. The longitudinal air plate assembly 91 is arranged on the base 9, and the left and right air sweeping is controlled by taking the driving motor 92 as a driving source.
