Specifically, as shown in fig. 1 and 2, the air duct member 1 defines an air outlet passage 11, and one end of the air passage 11 is formed as an air outlet 12. It can be understood that the air duct member 1 may define the air flow channel 11, so that the air flow can move along a specific track, and at the same time, the air flow channel 11 may be used to separate the heat exchange air flow from other components of the indoor unit 100 of the air conditioner, thereby reducing energy loss during the air flow. In one example of the present invention, one end of the air flow channel 11 is formed as an air inlet 13, the other end of the air flow channel 11 is formed as an air outlet 12, and the air inlet 13 is disposed spaced apart from the air outlet 12.

As shown in fig. 1 and 2, the distance between the two opposite side walls of the diversion cavity 21 gradually increases in the direction of the airflow. It is understood that by increasing the distance between the two opposite side walls of the baffle chamber 21 in the direction in which the air flow flows so that the inner wall surface of the baffle chamber 21 is disposed obliquely forward, the air flow can be blown outward along the wall surface of the baffle chamber 21 toward the obliquely forward direction according to the coanda effect.

It can be understood that the baffle 3 is installed on the front panel 2, the front panel 2 is located outside the air duct member 1, and the baffle 3 is installed on the front panel 2, so that the installation and fixing difficulty is relatively small. The deflector 3 is located downstream of the outlet 12 in the direction of flow of the air flow. It can be understood that the flow guide plate 3 is disposed at a distance from the air outlet 12, and the flow guide plate 3 is located downstream of the air outlet 12, and the flow guide plate 3 and the inner wall surface of the flow guide cavity 21 define an air outlet channel. The distance between the two opposite side walls of the diversion cavity 21 is gradually increased, so that the inner wall surface of the diversion cavity 21 is arranged forwards in an inclined manner, an air outlet duct which is inclined forwards can be defined by the inner wall surface of the diversion cavity 21 and the diversion plate 3, and when air flows along the air outlet duct, the air flows towards the inclined forwards direction, so that the problem of backflow of the air flow can be avoided, and the heat exchange efficiency of the indoor unit 100 of the air conditioner can be improved.

It can be understood that the air deflector 4 is disposed at the air outlet 12, and the air deflector 4 can be rotated to close the air outlet 12, or the air deflector 4 can be rotated to open the air outlet 12. In addition, by providing the rotatable air deflector 4, the flow direction of the air flow at the air outlet 12 can be changed by the air deflector 4. Specifically, the air guide plates 4 are plural, the plural air guide plates 4 are arranged at intervals in the length direction or the width direction of the air outlet 12, and the indoor unit 100 of the air conditioner further includes: and the connecting rod is rotatably connected with the plurality of air deflectors 4 and is used for driving the plurality of air deflectors 4 to synchronously rotate.

According to the air-conditioning indoor unit 100 provided by the embodiment of the utility model, the front panel 2 is arranged at the air outlet end of the air duct piece 1, the front panel 2 is provided with the diversion cavity 21 communicated with the air outlet 12, and the distance between the two opposite side walls of the diversion cavity 21 is gradually increased, so that the inner wall surface of the diversion cavity 21 is arranged obliquely forwards, an air outlet duct which is inclined forwards can be defined by the inner wall surface of the diversion cavity 21 and the diversion plate 3, and when air flows along the air outlet duct, the air can flow towards the oblique forwards direction, so that the problem of air flow backflow can be avoided, and the heat exchange efficiency of the air-conditioning indoor unit 100 can be improved.

In some embodiments of the present invention, as shown in fig. 1 and fig. 2, on the cross section of the diversion cavity 21, a connection line between the air outlet end of the diversion cavity 21 and the air outlet end of the airflow channel 11 is a reference line, an included angle between the reference line and the flow direction of the airflow at the air outlet 12 is α (α shown in fig. 1), and satisfies: alpha is more than 0 degree and less than or equal to 77 degrees. It can be understood that the extending direction of the reference line is substantially parallel to the flowing direction of the airflow in the air outlet duct, and the included angle between the reference line and the flowing direction of the airflow at the air outlet 12 is set to be greater than 0 ° and less than or equal to 77 °, so that not only the airflow in the air outlet duct can be prevented from blowing directly to the user, but also the airflow blown out from the air outlet duct can be effectively separated from the air inlet 13 of the indoor unit 100 of the air conditioner.

For example, in one example of the utility model, the angle between the reference line and the direction of flow of the airflow at the outlet 12 may be 10 °, 20 °, 30 °, 40 °, 50 °, 60 ° or 70 °. Specifically, the included angle between the reference line and the flowing direction of the airflow at the air outlet 12 can be set according to the model, size and applied environment of the indoor unit 100 of the air conditioner.

In some embodiments of the present invention, as shown in fig. 1 and 2, the sidewall of the cross-section of diversion cavity 21 includes: first extension section 22 and second extension section 23, first extension section 22 have relative first end and second end, and first end is connected with airflow channel 11's air-out end, and the second end extends along first direction, and second extension section 23 has relative third end and fourth end, and the third end is connected with the second end, and the fourth end extends along the second direction, and wherein, there is the contained angle between second direction and the first direction. It can be understood that the side wall of the cross section of the diversion cavity 21 includes two first extension sections 22 and two second extension sections 23 with different extension directions, so that the difficulty of processing the diversion cavity 21 can be reduced during processing, and the processing and forming are facilitated. For example, in one example of the present invention, the first extension 22 and the second extension 23 are both straight line segments.

In some embodiments of the present invention, as shown in fig. 1 and fig. 2, an included angle between the first direction and the flow direction of the airflow at the air outlet 12 is β 1(β 1 shown in fig. 1), and an included angle between the second direction and the flow direction of the airflow at the air outlet 12 is β 2(β 2 shown in fig. 1), and satisfies: beta 1 is more than beta 2. It can be understood that the airflow blown out from the air outlet 12 moves along the first extending section 22 first, and then moves along the second extending section 23, because the included angle between the first extending section 22 and the flow direction of the airflow at the air outlet 12 is greater than the included angle between the second extending section 23 and the flow direction of the airflow at the air outlet 12, when the airflow transitions from the first extending section 22 to the second extending section 23, the airflow may deflect towards the front of the air outlet 12, and the deflected airflow may move towards the direction deviating from the air inlet 13 under the action of inertia, so as to further reduce the probability of backflow, and further improve the heat exchange efficiency of the indoor air conditioner 100.

In some embodiments of the present invention, the inner sidewall of diversion chamber 21 is formed in an arc shape. It can be understood that, by setting the inner side wall of the diversion cavity 21 to be arc-shaped, the resistance of the airflow flowing through the inner side wall of the diversion cavity 21 can be reduced, so that the energy loss of the airflow flowing through the inner side wall of the diversion cavity 21 can be reduced, the energy consumption of the indoor unit 100 of the air conditioner is reduced, and the heat exchange efficiency of the indoor unit 100 of the air conditioner is further improved.

In some embodiments of the utility model, the inner side walls of the baffle chamber 21 are concave towards the direction away from the baffle 3. Therefore, when the airflow is on the inner side wall of the diversion cavity 21, the airflow can deflect towards the front of the air outlet 12, and the deflected airflow can move towards the direction deviating from the air inlet 13 under the action of inertia, so that the probability of backflow is further reduced, and the heat exchange efficiency of the indoor air conditioner 100 is further improved.

In some embodiments of the utility model, the baffle 3 is rotatably connected to the front panel 2. It can be understood that the air outlet duct is defined by the guide plate 3 and the inner wall surface of the guide cavity 21, and the position and the radial width of the air outlet duct can be changed by rotating the guide plate 3, so that the air outlet direction and the strength of the air outlet force can be adaptively adjusted.

For example, in an example of the present invention, the baffle 3 is rotatably disposed on the front panel 2 through a connecting bracket, specifically, the indoor air conditioner 100 is provided with a driving mechanism 5, one end of the connecting bracket away from the baffle 3 is connected to an output shaft of the driving mechanism 5, and the connecting bracket and the baffle 3 can be driven to rotate synchronously by the rotation of the driving mechanism 5. Wherein the output shaft of the drive mechanism 5 can be switched between clockwise and counter-clockwise rotation.

In some embodiments of the utility model, the deflector 3 is adapted to rotate between a first position in which the deflector 3 is directly opposite the outlet mouth 12 and the deflector 3 is spaced from the side walls of the deflector chamber 21, and a second position. It can be understood that, in the first position, the guide plate 3 is just right with the air outlet 12, that is to say, the guide plate 3 can shelter from the air current of blowing out from the air outlet 12 in the position just right to the air outlet 12, avoid the air current to blow the user directly, and the guide plate 3 sets up with the lateral wall interval of water conservancy diversion chamber 21, the both ends of guide plate 3 all separate with two lateral walls of water conservancy diversion chamber 21, from this the guide plate 3 can inject an air outlet duct respectively with two lateral walls of both sides, the air current that shelters from through the guide plate 3 can blow to the interior space from the air outlet duct of both sides.

In some embodiments of the utility model, in the second position, one end of the baffle 3 abuts the side wall of the baffle cavity 21. It can be understood that one end of the deflector 3 may abut against the sidewall of the deflector cavity 21, so that the airflow can only be blown out from the outlet duct at the other end of the deflector 3, and thus the specific outlet position of the indoor air conditioner 100 can be changed by rotating the deflector 3.

In some embodiments of the present invention, as shown in fig. 1 and 3, there are two baffles 3, two baffles 3 are symmetrically arranged in the width direction of the air outlet 12, and in the second position, the two baffles 3 are spaced apart in the width direction of the air outlet 12. It can be understood that, in the second position, one side of each air deflector 4 departing from each other is respectively abutted to two side walls of the air guide cavity 21 and one side of each two adjacent air deflectors 3 is arranged at an interval, so that the air flow blown out from the air outlet 12 can be blown out through one end of each two adjacent air deflectors 3, thereby providing a strong air supply experience for a user, and simultaneously reducing the energy loss when the air flow flows through the air deflectors 3, further improving the air supply distance of the air-conditioning indoor unit 100, and further improving the heat exchange efficiency of the air-conditioning indoor unit 100.

For example, in an example of the present invention, two guide plates 3 are respectively rotatably disposed on the front panel 2 through two connecting brackets, the front panel 2 is provided with a driving mechanism 5, one end of each connecting bracket, which is away from the guide plate 3, is connected to an output shaft of the driving mechanism 5, specifically, two driving mechanisms 5 are provided, the two driving mechanisms 5 are correspondingly matched with the two connecting brackets one by one, and the two connecting brackets and the two guide plates 3 can be respectively driven to rotate through the rotation of the two driving mechanisms 5. Wherein, the two driving mechanisms 5 can rotate synchronously or independently.

Specifically, in one example of the present invention, the two air deflectors 4 can be driven to synchronously rotate in the direction away from each other by the synchronous rotation of the two driving mechanisms 5, so that air supply to the area directly opposite to the air outlet 12 can be realized; or the two air deflectors 4 are driven to synchronously rotate in the direction of approaching each other, so that air supply in two side areas can be realized.

In another example of the present invention, the two driving mechanisms 5 are independently rotated, and when the two air deflectors 3 are both located at positions opposite to the air outlet 12, only the driving mechanism 5 on the left side may be controlled to operate, so that the driving mechanism 5 on the left side drives the air deflector 3 on the left side to rotate in a direction away from the other air deflector 3, thereby air flow may be supplied from a space between the two air deflectors 3, or may be supplied from an air outlet duct between the air deflector 3 on the right side and the right side wall of the air guide cavity 21.

Of course, it is also possible to only control the right driving mechanism 5 to operate, so that the right driving mechanism 5 drives the right guide plate 3 to rotate toward the direction away from the other guide plate 3, thereby the air flow can be supplied from the space between the two guide plates 3, or supplied from the air outlet duct between the left guide plate 3 and the right side wall of the guide cavity 21. Of course, the left driving mechanism 5 and the right driving mechanism 5 may be controlled to operate according to the chronological order.

In some embodiments of the present invention, the inner wall surface of the baffle 3 facing the baffle chamber 21 is formed in an arc shape. It can be understood that, by setting the inner wall surface of the flow guide plate 3 facing the flow guide cavity 21 to be arc-shaped, the resistance of the airflow flowing through the inner wall surface of the flow guide plate 3 can be reduced, so that the energy loss of the airflow flowing through the flow guide plate 3 can be reduced, the energy consumption of the indoor air conditioner 100 is reduced, and the heat exchange efficiency of the indoor air conditioner 100 is further improved.

The air deflector 4 is disposed at the air outlet 12, and the air deflector 4 can be rotated to close the air outlet 12, or the air deflector 4 can be rotated to open the air outlet 12.

An air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

An air conditioner according to an embodiment of the present invention includes: the air conditioning indoor unit 100 described above.

For example, in one example of the present invention, an air conditioner includes an air conditioner indoor unit 100 and an air conditioner outdoor unit. The air conditioner has a cooling mode and a heating mode. In a refrigeration mode, a refrigerant is compressed in a compressor, original low-temperature low-pressure refrigerant gas is compressed into high-temperature high-pressure superheated steam, the high-temperature high-pressure superheated steam is discharged from an exhaust port of the compressor, and the high-temperature high-pressure superheated steam enters from an inlet of a four-way valve. The high-temperature and high-pressure superheated steam is cooled in the condenser, and the superheated refrigerant is changed from a gaseous state to a liquid state through the cooling heat dissipation effect of the fan. The air conditioner has one-way valve between the indoor evaporator and the outdoor condenser to control the flow direction of refrigerant, and has the functions of one-way connection and reverse cut-off. When cooled low-temperature high-pressure refrigerant flows through, a one-way valve in the refrigerating system is switched on, and a heating one-way valve is switched off. Therefore, the refrigerant liquid passes through the check valve, then passes through the filter drier and the capillary tube for throttling and pressure reduction, and flows into the indoor unit 100 of the air conditioner through the liquid tube (thin tube). The refrigerant liquid absorbs heat and vaporizes in the evaporator of the indoor unit 100 of the air conditioner, the temperature of the ambient air temperature decreases, and the cool air is blown into the room by the cross flow fan. The gasified refrigerant is sent back to the outdoor unit of the air conditioner through the gas pipe (thick pipe), and the four-way valve is connected with the indoor evaporator pipe and is communicated with the air suction pipe of the compressor, so that the refrigerant gas is sucked back into the compressor through the air suction port of the compressor and is compressed into high-temperature high-pressure superheated steam again to maintain the refrigeration cycle.

In the heating mode, the high-temperature and high-pressure superheated steam compressed by the compressor is discharged from an exhaust port of the compressor, and is directly sent into the evaporator through the four-way valve by connecting the indoor evaporator tubes, at this time, the evaporator acts as a condenser, the superheated steam is radiated by the heat exchanger of the indoor unit 100 of the air conditioner, and the radiated heat is blown out from an air port by the cross-flow fan. The superheated steam is cooled to form a low-temperature high-pressure liquid, and then returned from the indoor unit 100 to the outdoor unit through a liquid pipe (narrow pipe). At this time, in the heating cycle, the heating check valve is turned on and the cooling check valve is turned off according to the flow direction of the refrigerant. The refrigerant liquid is sent to the condenser of the outdoor unit of the air conditioner after passing through the heating one-way valve, the drying filter and the throttling components such as capillary tubes. In contrast to the function of the evaporator, this is the effect of the condenser, which corresponds to the effect of the evaporator in the case of refrigeration. The low-temperature low-pressure refrigerant completes the vaporization process, the refrigerant liquid absorbs a large amount of heat to the outside, and is changed into dry saturated vapor again, and the cold air is blown out of the air conditioner outdoor unit by the axial flow fan. The dry saturated steam finally enters from the pipe orifice of the outdoor condenser and returns to the air suction port of the compressor through the air suction pipe of the compressor, and the heating cycle is maintained.
