Fig. 1 is a schematic sectional view of an air conditioning indoor unit according to an embodiment of the present utility model, as shown in fig. 1, and referring to fig. 2 to 6, an embodiment of the present utility model provides an air conditioning indoor unit including:

the casing 1, the casing 1 includes first mating surface and second mating surface that contact with two walls of indoor corner respectively. The front surface of the casing 1 is provided with an air return port communicated with the room.

The heat exchange part 11 is arranged in the casing, and is configured to suck air flow from the return air inlet, heat or refrigerate the air flow, and then make the air flow out of the casing 1.

And a functional unit 12, wherein the functional unit 12 is disposed in the casing 1 and is configured to suck air flow from the return air inlet and make the air flow out of the casing 1.

Specifically, the heat exchange portion 11 is activated, and air flow is sucked from the room through the return air inlet, and after being sucked by the heat exchange portion 11, the air flow exchanges heat with the heat exchange portion 11 to become heat exchange air, and then is blown into the room through the air conditioning indoor unit.

The functional unit 12 is activated, and air flow is sucked from the room through the return air port, and the air flow is sucked into the functional unit 12, and then blown into the room through the air conditioning indoor unit. The functional unit 12 blows out functional air, which is indoor uniform air at this time.

The indoor unit of the air conditioner has the indoor air homogenizing function, so that the circulation of indoor air is promoted, and meanwhile, the air supply wind sense of the indoor unit of the air conditioner is softer.

The included angle between the first mating surface and the second mating surface is preferably 90 degrees, so that the indoor unit of the air conditioner can be installed at an indoor corner. When the indoor unit of the air conditioner is installed at an indoor corner, the first matching surface is attached to the wall of the indoor corner, and the second matching surface is attached to the wall of the indoor corner.

Of course, the included angle between the first mating surface and the second mating surface may be other angles, for example, when the angle of the indoor corner is 60 °, in order to enable the indoor unit of the air conditioner to be installed at the corner, the included angle between the first mating surface and the second mating surface may be designed to be 60 °. The first matching surface and the second matching surface of the indoor unit of the air conditioner are tightly attached to the wall surface of the indoor corner.

As shown in fig. 2, the air conditioner indoor unit of the present utility model is provided with the heat exchange part 11 and the functional part 12, so that the air conditioner indoor unit can blow and exchange hot air and indoor uniform air, and the air conditioner indoor unit has soft air supply sense.

In some embodiments of the utility model, the first mating surface or the second mating surface is provided with an opening 124 in communication with the outside.

The functional part 12 communicates with the opening 124 to draw in an air flow from the opening 124 and let the air flow out of the casing 1.

Specifically, the functional unit 12 blows functional wind, which may be indoor uniform wind and/or fresh air. The opening 124 is preferably disposed on the second mating surface.

On the basis that the functional part 12 can blow indoor uniform wind, if the functional part 12 is communicated with the opening 124, the functional part 12 is communicated with the outside, so that the functional part 12 can introduce air flow from the outside through the opening 124 and form fresh air, and the fresh air flows out of the casing 1. The function part 12 of the air conditioner indoor unit can blow not only indoor uniform air but also fresh air. Thereby meeting different requirements of users for fresh air and indoor uniform air and improving the cost performance of the indoor unit of the air conditioner.

In the above process, since the functional part 12 is located in the casing 1, the first mating surface and the second mating surface thereof may be preferentially disposed at the indoor corner; the distance between the functional part 12 and the indoor wall is shorter, so that when the air conditioner indoor unit needs to blow fresh air, the path required by the air entering the indoor unit body part from the outside is shorter, the time for blowing fresh air by the air conditioner indoor unit is shortened, and the air outlet efficiency of the air conditioner indoor unit is improved.

As shown in fig. 1, in some embodiments of the utility model, the air conditioning indoor unit further comprises a first stop device 125 and/or a second stop device 126. The first stopping device 125 is disposed in the casing 1, and is used for controlling the on-off between the air return port and the functional part 12. A second stop device 126 is disposed in the casing 1 for controlling the connection and disconnection between the opening 124 and the functional portion 12.

Specifically, when the functional air to be blown by the functional unit 12 is indoor uniform air, the first stopper 125 and the second stopper 126 are adjusted to allow the functional unit 12 to communicate with the return air inlet and to prevent the functional unit 12 from communicating with the opening 124. When the functional part 12 works, the functional part 12 only sucks air flow from the air return opening, namely, only sucks air flow from the indoor, so that indoor uniform air is blown, and then the indoor uniform air flows out of the machine shell 1, so that the indoor uniform air is blown by the indoor unit of the air conditioner.

When the functional air blown by the functional unit 12 is fresh air, the first stopper 125 and the second stopper 126 are adjusted so that the functional unit 12 is not communicated with the return air inlet and so that the functional unit 12 is communicated with the opening 124. When the functional part 12 is operated, the functional part 12 sucks in the air flow only from the opening 124, that is, the air flow only from the outside, thereby realizing blowing of the fresh air, and then the fresh air is caused to flow out of the casing 1, thereby realizing blowing of the fresh air by the indoor unit of the air conditioner.

This arrangement allows the functional unit 12 to switch between blowing indoor air and blowing fresh air.

As shown in fig. 4, in some embodiments of the utility model, the return air inlet includes a heat exchange air return opening 111 and a functional air return opening 127, and the functional air return opening 127 is disposed at the lower side of the heat exchange air return opening 111.

The first stopper 125 is a first baffle plate and is disposed inside or outside the functional air return opening 127 in a vertically movable manner.

The second stopper 126 is a second baffle plate and is disposed inside or outside the opening 124 in a vertically movable manner.

Specifically, the first shutter has a first position at which the functional air return opening 127 can communicate with the functional portion 12, and a second position at which the functional air return opening 127 can not communicate with the functional portion 12; the first baffle can move up and down between a first position and a second position and is switched;

The second shutter has a third position in which the opening 124 can communicate with the functional portion 12, and a fourth position in which the opening 124 can not communicate with the functional portion 12; the second baffle can move up and down between a third position and a fourth position and is switched;

when the functional air to be blown by the functional unit 12 is indoor uniform air, the first baffle is positioned at the first position, the second baffle is positioned at the fourth position, the functional unit 12 is communicated with the return air inlet, and the functional unit 12 is not communicated with the opening 124. When the functional part 12 is operated, the functional part 12 sucks air flow only from the functional air return port 127, that is, only from the indoor, thereby realizing that indoor uniform air is blown, and then the indoor uniform air flows out from the casing 1, thereby realizing that the indoor unit of the air conditioner blows indoor uniform air.

When the functional air blown by the functional unit 12 is fresh air, the first baffle is set at the second position, and the second baffle is set at the third position, so that the functional unit 12 is not communicated with the functional air return opening 127, and the functional unit 12 is communicated with the opening 124. When the functional part 12 is operated, the functional part 12 sucks in the air flow only from the opening 124, that is, the air flow only from the outside, thereby realizing blowing of the fresh air, and then the fresh air is caused to flow out of the casing 1, thereby realizing blowing of the fresh air by the indoor unit of the air conditioner.

As shown in fig. 4, in some embodiments of the utility model, both sides of the front surface of the cabinet 1 are provided with air blowing portions 13, and each air blowing portion 13 extends in the vertical direction. Each air supply portion 13 communicates with the functional portion 12 and the heat exchanging portion 11.

Specifically, the functional part 12 serves to convert an air flow into functional wind. When the air conditioning indoor unit cools/heats, it causes air to flow through the functional portion 12, and then the air flow is converted into functional wind. And then the functional air flows out of the air conditioning indoor unit through the air supply parts 13 provided at both sides of the front surface of the cabinet 1.

The heat exchange part 11 is used for exchanging heat with gas, so that the air flow flowing through the heat exchange part 11 is converted into heat exchange air, and the air conditioner indoor unit can perform refrigeration/heating conveniently. When the air conditioner cools/heats, it causes the gas to flow through the heat exchanging part 11, and then the gas exchanges heat with the heat exchanging part 11, thereby being converted into heat exchanging wind. And then the heat exchanging air flows out of the air conditioning indoor unit through the air supply parts 13 provided at both sides of the front surface of the cabinet 1, thereby changing the temperature of the indoor air.

The air conditioner indoor unit is convenient to cool/heat, so that the temperature of indoor air is changed, and the requirement of a user on the indoor temperature is met.

As shown in fig. 3 and 4, in some embodiments of the utility model, an air supply duct 14 that communicates with the two air supply portions 13, respectively, is further provided in the chassis 1. The inlet of the air supply duct 14 communicates with both the functional unit 12 and the heat exchanging unit 11.

Specifically, inlets of the two air supply channels 14 are respectively communicated with the functional part 12 and the heat exchange part 11, and air outlets of the two air supply channels 14 are respectively communicated with the air supply parts 13 positioned at two sides of the casing 1.

When the functional unit 12 is operated and the heat exchanging unit 11 is not operated, the functional unit 12 is activated, and an air flow is sucked from the outside through the opening 124 provided in the first mating surface or the second mating surface, and the air flow is sucked into the functional unit 12 and then converted into functional wind. The functional air is divided into two when flowing out from the functional part 12 and respectively enters the inlets of the two air supply air channels 14, and then the two functional air flows out from two sides of the air conditioning indoor unit through the outlets of the two air supply air channels 14 and the two air supply parts 13 in sequence, so that the air conditioning indoor unit blows the functional air indoors.

When the heat exchange part 11 is operated and the functional part 12 is not operated, the heat exchange part 11 is started to promote the gas to flow through the heat exchange part 11, and then the gas exchanges heat with the heat exchange part 11, so that the gas is converted into heat exchange wind. The heat exchange air is divided into two when flowing out from the heat exchange part 11 and respectively enters the inlets of the two air supply air channels 14, and then the two heat exchange air flows out from the two sides of the air conditioning indoor unit through the outlets of the two air supply air channels 14 and the two air supply parts 13 in sequence, so that the air conditioning indoor unit blows the heat exchange air indoors.

When the heat exchange part 11 and the functional part 12 work simultaneously, the heat exchange part 11 and the functional part 12 start simultaneously, and the heat exchange part 11 sucks air flow from the room and converts the air flow into heat exchange air; the functional part 12 introduces an air flow from outside or inside and converts it into functional wind. And then the heat exchange air and the functional air flow into the air supply air channels 14 and respectively flow out through the outlets of the two air supply air channels 14 and the air supply part 13 in sequence. Wherein, one part of the two air supply parts 13 flow out the heat exchange air, and the other part flows out the functional air. The arrangement enables the air conditioner indoor unit to blow functional air and heat exchange air simultaneously, so that the air conditioner indoor unit can cool/heat, keep indoor air fresh and clean, and has better user experience.

As shown in fig. 5, in some embodiments of the present utility model, the two air supply ducts 14 are a first air supply duct and a second air supply duct, respectively;

The first air supply duct is close to the first matching surface, the duct wall of the first air supply duct close to the first matching surface comprises a first air outlet section, and the first air outlet section is connected with the corresponding air supply part 13 and is parallel to the first matching surface;

The second air supply duct is close to the second matching surface, and the duct wall of the second air supply duct close to the second matching surface comprises a second air outlet section, and the second air outlet section is connected to the corresponding air supply part 13 and is parallel to the second matching surface.

The air duct wall of the first air supply air duct far away from the first matching surface comprises a third air outlet section, the third air outlet section is connected with the corresponding air supply part 13, and an included angle between a tangent plane at the tail end of the third air outlet section and the first matching surface is smaller than or equal to 45 degrees;

The air duct wall of the second air supply air duct far away from the second matching surface comprises a fourth air outlet section, the fourth air outlet section is connected to the corresponding air supply part 13, and an included angle between a tangent plane at the tail end of the fourth air outlet section and the second matching surface is smaller than or equal to 45 degrees.

Specifically, an included angle between a tangential plane at the tail end of the third air outlet section and the first matching surface is 45 degrees, and an included angle between a tangential plane at the tail end of the fourth air outlet section and the second matching surface is 45 degrees.

Of course, the first air supply duct further comprises other air outlet sections, the other air outlet sections are connected with the first air supply section and the third air supply section to form the first air supply duct 11 together, preferably, the first air outlet section and the third air outlet section form an outlet of the first air supply duct together, and the outlet of the first air supply duct is one of the air supply parts 13; the other air outlet sections are respectively connected with the first air outlet section and the third air outlet section and form an inlet of the first air supply duct.

In the air supply process of the first air supply duct, after the air flow is blown into the first air supply duct, the air flow respectively passes through the first air outlet section and the third air outlet section; when the air flow passes through the first air outlet section, the air flow flows along the direction parallel to the wall edge of the indoor corner under the guidance of the first air outlet section; the arrangement is such that after the air flow has exited from the first supply air duct, the air flow flows toward and along the wall of the corner of the room.

In addition, the second air supply duct further comprises other air outlet sections, the other air outlet sections are connected with the second air supply section and the fourth air supply section to jointly form an inlet and an outlet of the second air supply duct, preferably, the second air outlet section and the fourth air outlet section jointly form an outlet of the second air supply duct, and the outlet of the second air supply duct is the other air supply part 13; the other air outlet sections are respectively connected with the second air outlet section and the fourth air outlet section and form an inlet of the second air supply duct.

In the air supply process of the second air supply duct, after the air flow is blown into the second air supply duct, the air flow respectively passes through the second air outlet section and the fourth air outlet section; when the air flow passes through the second air outlet section, the air flow flows along the direction parallel to the wall edge of the indoor corner under the guidance of the second air outlet section; the arrangement is such that after the air flow has exited from the second supply air duct, the air flow flows toward and along the wall of the corner of the room.

In some embodiments of the utility model, the inlet of each air supply duct 14 is partially a functional air communication port communicating with the functional portion 12, and the rest of the inlet of each air supply duct 14 is a heat exchange air communication port communicating with the heat exchange portion 12. The functional air communication port and the heat exchange air communication port are sequentially arranged in height.

Specifically, the functional portion 12 and the heat exchanging portion 11 are disposed in order in the up-down direction, and the heat exchanging portion 11 is preferentially disposed above the functional portion 12. The inlet of each air supply duct 14 extends in the up-down direction, and the length of the inlet of each air supply duct 14 is greater than the sum of the lengths of the functional portion 12 and the heat exchanging portion 11 in the up-down direction. Correspondingly, the heat exchange air communication port and the functional air communication port are arranged in the up-down direction once, and the heat exchange air communication port is arranged above the functional air communication port. When the air conditioner indoor unit supplies air, heat exchange air is blown upward, and functional air is blown downward. Since the upper body of the user is located in the middle of the indoor space, the cabinet air conditioner is generally 1.7m-1.8m in height. Therefore, when the heat exchange air is blown by the air conditioner indoor unit, the heat exchange air can be blown to a user, so that the user can more obviously feel the refrigerating/heating effect brought by the heat exchange air, and the user experience is better.

In some embodiments of the present utility model, the air supply part 13 is an air supply port extending in a vertical direction, or the air supply part 13 includes a functional air supply port provided in correspondence in height with the functional air communication port and a heat exchange air supply port provided in correspondence in height with the heat exchange air communication port.

Each air supply duct 14 is vertically communicated, or a partition board is arranged in each air supply duct 14 and is positioned between the adjacent functional air communication ports and the heat exchange air communication ports. The partition is movably provided to move to the inside and outside of the supply air duct 14.

Specifically, when the air blowing portion 13 is an air blowing port extending in the vertical direction, the air blowing port is preferably rectangular, and the heights of the two air blowing ports coincide with the lengths of the inlets of the two air blowing ducts 14. When the air supply part 13 includes a heat exchange air supply port and a functional air supply port, preferably, a partition plate is provided in each air supply duct 14, and divides the space in the air supply duct 14 into a heat exchange space and a functional air space. The heat exchange space is communicated with the heat exchange air communication port and the heat exchange air supply port; the functional air space is communicated with the functional air communication port and the functional air supply port. Further, the partition is disposed horizontally and movably within the supply air duct 14, having a first position within the supply air duct 14 and a second position not within the supply air duct 14.

When the partition board is at the first position and is positioned in the air supply duct 14, the heat exchange space and the functional air space in the air supply duct 14 are isolated, that is, the heat exchange space and the functional air space are not communicated. When the heat exchange part 11 works, heat exchange air enters the heat exchange space from the heat exchange air communication port and flows out from the heat exchange air supply port; when the functional part 12 works, functional wind enters the functional wind space from the functional wind communication port and flows out from the functional wind supply port; the arrangement avoids mutual interference of the heat exchange air and the functional air, thereby avoiding the influence on the refrigerating/heating effect of the heat exchange air.

When the partition is in the second position, it is outside the air supply duct 14, and communicates the heat exchanging space with the functional air space. When the heat exchange part 11 works, heat exchange air enters the heat exchange space from the heat exchange air communication port; when the functional unit 12 is operated, functional wind enters the functional wind space from the functional wind communication port. Because the heat exchange space is communicated with the functional air space, the heat exchange air and the functional air flow out from the heat exchange air supply port and/or the functional air supply port after being mixed in the air supply duct 14. The arrangement makes the hot air exchange and the functional air mix, so that the air sense is softer when the indoor unit of the air conditioner supplies air.

As shown in fig. 1, in some embodiments of the utility model, the functional part 12 includes a fan 121, an air duct 122, and two filter modules 123. The fans 121 are centrifugal fans, and the number of inlets is two, and the fans are respectively arranged forward and backward.

The inlet of the air duct 122 communicates with the opening 124. The outlet of the air duct 122 is directed forward toward the rearward inlet of the fan 121 and communicates with the inlet of the fan 121. The forward facing inlet of the fan 121 is aligned with the functional air return 127 and communicates with the functional air return 127. In some embodiments of the present utility model, the second stopping device 126 is a second baffle, and is disposed at the outlet of the air duct 122 in a manner of moving up and down.

The fans 121 have two outlets, which communicate with the two functional wind communication ports 127, respectively.

The two filter modules 123 are respectively disposed at the two functional wind communication ports.

The second stopping device 126 is a second baffle, and is disposed on the outer side of the outlet of the air duct 122 in a vertically movable manner.
