In the description of the present embodiment, it is to be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "depth", etc. indicate orientations or positional relationships are based on the orientations in the normal use state of the cabinet air-conditioning indoor unit 1 as references, and can be determined with reference to the orientations or positional relationships shown in the drawings, for example, "front" indicating an orientation refers to a side facing a user. This is merely to facilitate describing the invention and to simplify the description and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operate in a particular orientation, and thus should not be construed as limiting the invention.
The present invention first provides an air conditioner, which may generally include an indoor unit installed indoors and an outdoor unit installed outdoors. The air conditioner can realize refrigeration or heating by using a circulating refrigeration system, and the circulating refrigeration system realizes heat transfer by using compression phase change circulation of refrigerant in a compressor, an outdoor unit heat exchanger, an indoor unit heat exchanger and a throttling device. In the air conditioner, the refrigerating system can also be provided with a reversing valve to change the flow direction of the refrigerant, so that the indoor unit heat exchanger can alternately serve as an evaporator or a condenser to realize the refrigerating or heating function. Since the circulating refrigeration system in the air conditioner is well known to those skilled in the art, the operation principle and construction thereof will not be described herein.
Referring to fig. 1 to 5, in some embodiments, the present invention further provides a cabinet indoor unit capable of exhausting air from both sides to avoid direct blowing of a user. The cabinet air conditioner indoor unit 1 may further include a cabinet 10, an air duct frame 20, and a cross flow fan 40.
The cabinet 10 protects the whole indoor unit 1 of the cabinet air conditioner, and an air inlet grille 12 is provided at the rear side of the cabinet 10, a heat exchange air flow inlet is formed on the air inlet grille 12, and an air outlet 142 is provided at the front side of the cabinet 10.
The air duct frame 20 is disposed inside the casing 10, a heat exchange air duct 222 is formed on the air duct frame 20, and the heat exchange air duct 222 has an air inlet side opened toward the heat exchange air flow inlet and an air outlet side opened toward the air outlet 142. The air duct skeleton 20 further has an air outlet air duct 224 connected between the air outlet side and the air outlet 142 to guide the heat exchange air flow in the heat exchange air duct 222 to the air outlet 142. A plurality of swing blades 226 can be further arranged in the air outlet duct 224 to adjust the direction of the heat exchange air flow through up-and-down swing.
The evaporator 30 is installed on the air duct frame 20 and covers the heat exchange air duct 222 to exchange heat with air sucked into the casing 10 from the heat exchange air flow inlet, and the heat exchanged air is discharged into the room through the air outlet side of the air duct frame 20 and the air outlet 142 of the casing 10, thereby realizing refrigeration or heating.
The cross flow fan 40 is installed in the heat exchange duct 222 in a lateral direction for inducing indoor air flow into the cabinet 10 from the heat exchange air flow inlet to exchange heat with the evaporator 30 and finally discharged from the air outlet 142.
In some embodiments, the casing 10 further has an air outlet front wall 14, the air outlet 142 is disposed at a lateral middle portion of the air outlet front wall 14, and the air outlet 142 may be elongated and extend along a height direction of the casing 10, so as to fully utilize a shape of the casing 10 and obtain a larger air outlet area.
The cabinet air conditioner indoor unit 1 may further include an air outlet grill 50 and an air guide assembly. The air outlet grill 50 may be provided with air holes so as to pass through the heat exchange air flow discharged from the air outlet 142. The air outlet grille 50 has a main body surface 510 and two side end surfaces 520, the main body surface 510 is disposed in front of the air outlet front wall 14 in a facing manner, and the two side end surfaces 520 are respectively formed at both lateral ends of the main body surface 510 and are engaged with both lateral side edges of the air outlet front wall 14. The air guide assembly comprises two air guide plates 60, wherein the two air guide plates 60 are transversely arranged between the air outlet front wall 14 and the main body surface 510 and positioned in front of the air outlet 142, and the two air guide plates 60 are respectively arranged to rotate around the position close to the main body surface 510. The air guide assembly can realize different air outlet effects by rotating the two air guide plates 60, and specifically, the air guide assembly at least can have two side air outlet states, a front air outlet state, a wind dispersing state and the like.
Referring to fig. 3, when the air guiding assembly is in the air-out state at two sides, the two air guiding plates 60 can rotate together, so that the two air guiding plates are transversely spliced in front of the air outlet 142 to block the heat exchange air flow from penetrating forward, and the two air guiding plates 60 transversely spliced can guide part of the heat exchange air flow to penetrate through the two side end faces 520, so that the user directly in front of the direct-blowing machine shell 10 is avoided.
In this state, although the two air deflectors 60 do not completely cover the main body surface 510, since the two air deflectors 60 are transversely spliced in front of the air outlet 142, the heat exchange air flow discharged from the air outlet 142 is first guided transversely by the two air deflectors 60, so that the heat exchange air flow can be almost completely discharged through the two side end surfaces 520, and thus, the direct blowing of the user is avoided.
Referring to fig. 4, when the air guide assembly is in the front air outlet state, the two air guide plates 60 can rotate to engage with two sides of the air outlet 142 respectively, so as to guide the heat exchange air flow to penetrate out from the main body surface 510. That is, the two air deflectors 60 may form an air outlet channel extending back and forth between the air outlet 142 and the main body surface 510 by rotating, and the heat exchange air flow discharged from the air outlet 142 may be almost entirely discharged to the main body surface 510 along the air outlet channel and finally discharged forward to the indoor environment through the main body surface 510, so that forward aggregate air supply can be realized.
Referring to fig. 5, when the air guiding assembly is in the air dispersing state, the two air guiding plates 60 can also rotate to make one end far away from the pivot axis x be located in front of the air outlet 142 and extend obliquely from back to front and towards two lateral sides, at this time, the two air guiding plates 60 are not spliced, so that a part of heat exchanging air flow can be discharged to the indoor environment forwards through the gap between the two air guiding plates 60 and through the main body surface 510, and another part of heat exchanging air flow can be discharged to the indoor environment forwards left and right respectively through the combination of the main body surface 510 and the side end surface 520 by the oblique directions of the two air guiding plates 60, so as to realize air dispersing.
The two air deflectors 60 are synchronously controlled, and in addition, the two air deflectors 60 can be respectively controlled, and other different air outlet effects can be realized.
Referring to fig. 6, in some applications, the left air deflection 60 may be rotated such that its end remote from the pivot axis x is forward of the air outlet 142, while the right air deflection 60 is rotated into engagement with the air outlet 142 such that the right air deflection 60 blocks the flow of heat exchange air from exiting to the right and is only able to exit forward and to the left.
Referring to fig. 7, in some applications, the right air deflection 60 may be rotated such that its end remote from the pivot axis x is forward of the air outlet 142, while the left air deflection 60 is rotated into engagement with the air outlet 142 such that the left air deflection 60 blocks the flow of heat exchange air from exiting to the right and is only able to exit forward and to the right.
Therefore, in the cabinet air-conditioning indoor unit 1 of the present invention, since the main body surface 510 is oppositely disposed in front of the air outlet front wall 14, the two side end surfaces 520 are respectively formed at two lateral ends of the main body surface 510 and are engaged with two lateral edges of the air outlet front wall 14, the two air deflectors 60 are transversely disposed between the air outlet front wall 14 and the main body surface 510 and in front of the air outlet 142, the two air deflectors 60 can rotate around the pivot axis x adjacent to the main body surface 510, when the two air deflectors 60 are transversely spliced and positioned in front of the air outlet 142, the heat exchange air flow can be blocked from being transmitted forward, and part of the heat exchange air flow is guided to be transmitted through the two side end surfaces 520, so as to realize air dispersion, and when the two air deflectors 60 are mutually rotated far from each other, the two air deflectors are respectively engaged with two sides of the air outlet 142, so as to guide the heat exchange air flow to be transmitted from the main body surface 510, so as to realize forward aggregate air supply, and in a wide range of air supply can be realized.
Referring to fig. 3, in some embodiments, the body face 510 is open to the front of the air outlet 142 with an opening 530. The pivot axes x of the two air deflectors 60 are respectively vertically disposed at edges of both sides of the opening 530. When two air deflectors 60 are positioned in front of the air outlet 142 in a transversely spliced manner, the opening 530 is closed.
The two air deflectors 60 are further arranged to adapt the combination form of the two air deflectors after being transversely spliced to the shape and the size of the opening 530, so that when the two air deflectors 60 rotate around the pivot axis x of the two air deflectors to be transversely spliced at the opening 530, the opening 530 can be completely closed.
Referring to fig. 3, further, a sealing plate 540 is provided at the lateral center of the opening 530 in the vertical direction. When the two air deflectors 60 are transversely spliced and positioned in front of the air outlet 142, the ends of the two air deflectors 60, which are far away from the pivot axis x, face the rear side of the sealing plate 540, so as to seal the gap between the two air deflectors 60, and further reduce the forward air volume of the heat exchange air flow.
Referring to fig. 4, in addition, due to the opening 530, after the two air deflectors 60 are respectively engaged with two sides of the air outlet 142, the heat exchange air flow can be directly discharged into the indoor environment through the formed air outlet channel, so that the air speed loss is reduced.
Referring to fig. 4, in some embodiments, the edges of the lateral sides of the opening 530 are aligned front-to-back with the edges of the sides of the air outlet 142. Because the pivot shafts x of the two air deflectors 60 are respectively vertically disposed at the edges of the two sides of the opening 530, and the edges of the two lateral sides of the opening 530 are opposite to the edges of the two sides of the air outlet 142, when the two air deflectors 60 rotate to a front-back extending posture, the two air deflectors can be connected to the edges of the two sides of the air outlet 142, that is, the formed air outlet channel is opened forward entirely, so that the heat exchange air flow is discharged forward completely.
Further, referring to fig. 4, the width of the air deflector 60 is set to be the same as the distance between the air outlet front wall 14 and the main body surface 510. Under the condition that the edges of the two lateral sides of the opening 530 are opposite to the edges of the two sides of the air outlet 142, the width of the air deflector 60 is set to be the same as the distance between the air outlet front wall 14 and the main body surface 510, and one end of the air deflector 60 away from the pivot axis x can be connected to the edge of the air outlet 142, so that heat exchange air flow can be prevented from penetrating to the two sides, and the effect of aggregation air supply is further improved.
In some further embodiments, the edges of both sides of the opening 530 are further outward than the edges of both sides of the air outlet 142 in the lateral direction. That is, the lateral width of the opening 530 is set to be larger than the lateral width of the air outlet 142, and the projection of the air outlet 142 to the opening 530 is located inside the opening 530, so that the formed air outlet channel is approximately in a shape gradually expanding from back to front, and the air speed is reduced under the condition that the air quantity is unchanged.

The appearance wall 16 is configured as the appearance front wall 16 of the cabinet air-conditioning indoor unit 1, which is located at the forefront of the casing 10, and the air supply wall may be disposed further behind the appearance wall 16, and since the grille is disposed in front of the air supply wall and has the side end surface 520, the distance between the air supply wall and the appearance wall 16 can be used for accommodating the side end surface 520, so that the main body surface 510 of the air supply grille 50 protrudes from the appearance wall 16, and the aesthetic appearance of the cabinet air-conditioning indoor unit 1 is affected.
In some embodiments, the body face 510 of the air outlet grill 50 is contoured to match and level with the contour of the exterior front wall 16. As shown in fig. 9, for example, when the exterior wall surface 16 is a forwardly convex arc surface, then the body surface 510 should be provided as a forwardly convex arc surface. For another example, as shown in fig. 1 and 10, when the exterior wall surface 16 is planar, both the main body surface 510 and the side end surface 520 should be planar. The above examples are only adaptive matching in some situations, and other shapes of the casing 10 are naturally also present in the actual use process, which is not illustrated herein.
In some embodiments, as shown in fig. 1 and 9, the lateral width of the main body face 510 is set to be the same as the lateral width of the air outlet front wall 14, or as shown in fig. 10, the lateral width of the main body face 510 is set to be smaller than the lateral width of the air outlet front wall 14.
When the lateral width of the main body surface 510 is set to be the same as the lateral width of the air-out front wall 14, the two side end surfaces 520 may be engaged with both sides of the air-out front wall 14 in a front-back extending manner. When the lateral width of the main body surface 510 is set smaller than the lateral width of the air outlet front wall 14, the two side end surfaces 520 may be obliquely extended and engaged with two sides of the air outlet front wall 14.
Referring to fig. 11, the air conditioner 1 may further include a controller 800, the controller 900 may include a processor 810 and a memory 820, the memory 920 may have a machine executable program 922, and when the processor 910 executes the machine executable program 822, a control method of air supply of the air conditioner 1 may be implemented, and the control method may be based on the above-described cabinet indoor unit. Referring to fig. 12, the air supply control method may include the steps of:
step S910, an air supply mode of the cabinet indoor unit 1 is acquired, where the air supply mode includes a direct air blow preventing mode and a wind following mode. The signal may be a voice signal from a user or an electrical signal transmitted through a remote control. For example, a direct-blowing prevention mode key and a wind following mode key are arranged on the remote controller, when a user presses the direct-blowing prevention key, the air conditioner enters the direct-blowing prevention mode, presses the direct-blowing prevention key again, exits the automatic direct-blowing prevention mode, and resumes normal air supply logic.
Step S920, detecting the presence of the user in a plurality of preset areas in the indoor environment where the indoor unit 1 is located. In this step, the user position may be detected by a human body infrared sensing device provided on the cabinet 10, which may be provided at the lateral center of the cabinet.

As can be seen from the above analysis, since the main body surface 510 of the air outlet grille 50 is disposed in front of the air outlet front wall 14 in a facing manner, two side end surfaces 520 are respectively formed at both lateral ends of the main body surface 510 and are engaged with both lateral edges of the air outlet front wall 14, that is, the air outlet grille from which the heat exchange air flows are respectively discharged from the plurality of air supply directions. The air guide assembly can realize various air outlet modes through the rotation of the two air guide plates 60, so that the air guide assembly can be utilized to adjust the air supply direction, and further realize the direct blowing prevention function and the wind following function.
With reference to fig. 5, further, the plurality of preset areas are configured to divide three preset areas according to the extending directions of the two air deflectors 60 in the air dispersion state, where the three preset areas are a first area located between the extending directions of the air deflectors of the blade, and a second area and a third area located at the left side and the right side of the first area, respectively.
In some embodiments, when a user is detected in the blow-through preventing mode, the two air deflectors 60 are urged to rotate toward each other when the user is detected in the first area, so that the two air deflectors are positioned in front of the air outlet 142 in a transversely spliced manner, so as to block the heat exchange air flow from penetrating into the first area forward, and guide the heat exchange air flow to penetrate into the second area and the third area forward left and forward right respectively, that is, switch the air guiding assembly to the two-side air outlet state.
In some embodiments, when a user is detected in the second zone, the air deflection 60 proximate the second zone is caused to rotate into engagement with the edge of its corresponding air outlet 142 to block the flow of heat exchange air from exiting the second zone.

As shown in fig. 4, for example, when a user exists in the second area and a user also exists in the third area, the air guide plate 60 near the third area may be rotated to engage with the edge of the air outlet 142 corresponding to the air guide plate, i.e. the air guide assembly is switched to the front air outlet state. As shown in fig. 7, for example, when the second area has no user, the air deflector 60 near the third area may be rotated to extend from the rear to the front and out to realize the simultaneous air outlet to the front and out to the third area.
In some embodiments, when a user is detected in the third zone, the air deflection 60 proximate the third zone is caused to rotate into engagement with the edge of its corresponding air outlet 142 to block the flow of heat exchange air from exiting the third zone.
Similar to the above embodiment, when a user is detected in the third area, only the air deflector 60 adjacent to the third area may be rotated into engagement with the edge of its corresponding air outlet 142 to block the flow of heat exchange air from being discharged to the second area, and another air deflector 60 may be optionally provided.
In some embodiments, in conjunction with fig. 5, when it is detected that no user is present in all the areas, the air guiding assembly is controlled to switch to a dispersed air state to simultaneously discharge air to three preset areas.
Referring to fig. 5, in some embodiments, each preset area is divided into a near zone and a far zone according to a preset distance from the indoor unit; and the air supply control method comprises the following steps: detecting whether a user exists in a near area of each air supply area in a wind following mode; when a user is present in the vicinity of any one of the air blowing areas, the air speed of the cross flow fan 40 is reduced.
