The present invention firstly provides an air conditioner, which may generally include an indoor unit installed indoors and an outdoor unit installed outdoors. The air conditioner can use the cycle refrigeration system to achieve cooling or heating. The cycle refrigeration system uses the compression phase change cycle of the refrigerant in the compressor, outdoor unit heat exchanger, indoor unit heat exchanger, and throttling device to achieve heat transfer. In the air conditioner, the refrigeration system can also be equipped with a reversing valve to change the flow direction of the refrigerant, so that the heat exchanger of the indoor unit can be alternately used as an evaporator or a condenser to realize the cooling or heating function. Since the circulating refrigeration system in an air conditioner is well known to those skilled in the art, its working principle and structure will not be repeated here.

Referring to FIG. 1 to FIG. 5 , in some embodiments, the present invention also provides a cabinet-type indoor unit capable of blowing air from both sides to avoid blowing directly to users. The cabinet air conditioner indoor unit 1 may also include a casing 10 , an air duct frame 20 and a cross-flow fan 40 .

The casing 10 protects the entire indoor unit 1 of the cabinet air conditioner, and the rear side of the casing 10 is provided with an air inlet grille 12 on which a heat exchange air inlet is formed, and the front side of the casing 10 is provided with an air outlet 142.

The air channel frame 20 is arranged inside the casing 10, and the air channel frame 20 is formed with a heat exchange air channel 222, and the heat exchange air channel 222 has an air inlet side open toward the heat exchange air inlet and an air outlet toward the air outlet 142. side. The air channel frame 20 also has an air outlet air channel 224 connected between the air outlet side and the air outlet 142 to guide the heat exchange airflow in the heat exchange air channel 222 to the air outlet 142 . A plurality of swing vanes 226 can also be arranged in the air outlet duct 224 to adjust the direction of the heat exchange air flow by swinging up and down.

The evaporator 30 is installed on the air channel frame 20 and covers the heat exchange air channel 222 to exchange heat with the air sucked into the casing 10 from the heat exchange air inlet, and the heat-exchanged air passes through the air channel frame 20 The air outlet side of the air outlet and the air outlet 142 of the casing 10 are exhausted into the room to realize cooling or heating.

The cross-flow fan 40 is installed in the heat exchange air channel 222 along the horizontal direction, and is used to promote the indoor air flow from the heat exchange air inlet into the casing 10 to exchange heat with the evaporator 30 , and finally exhausted from the air outlet 142 .

In some embodiments, the casing 10 also has an air outlet front wall 14, and the air outlet 142 is arranged in the transverse middle of the air outlet front wall 14. Make full use of the shape of the casing 10 to obtain a larger air outlet area.

The cabinet-type air conditioner indoor unit 1 may also include an outlet grill 50 and an air guide assembly. Ventilation holes may be provided on the air outlet grille 50 so as to pass through the heat exchanging air 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 arranged facing the front of the air outlet front wall 14, and the two side end surfaces 520 are respectively formed on the lateral ends of the main body surface 510, and The lateral edges on both sides of the air outlet front wall 14 are connected. The wind deflector assembly includes two wind deflectors 60, and the two wind deflectors 60 are arranged laterally between the air outlet front wall 14 and the main body surface 510, in front of the air outlet 142, and the two wind deflectors 60 are configured to be respectively Rotate around the face 510 immediately adjacent to the main body. The wind guide assembly can realize different wind outlet effects through the rotation of the two air guide plates 60 , specifically, the air guide assembly can at least have a side air outlet state, a front air outlet state, and a diffuse air state.

Referring to Fig. 3, when the air guide assembly is in the state of blowing air from both sides, the two air guide plates 60 can be rotated close to each other, so that they are spliced horizontally in front of the air outlet 142, so as to prevent the heat exchange air from passing through forward. The two air deflectors 60 spliced horizontally can guide part of the heat exchange air to pass through the two side end surfaces 520 , so as to avoid direct blowing to users directly in front of the casing 10 .

It should be noted that, in this state, although the two wind deflectors 60 do not completely cover the main body surface 510, since the two wind deflectors 60 are spliced laterally in front of the air outlet 142, the exhaust air discharged from the air outlet 142 The hot air flow is firstly guided laterally by the two air deflectors 60 , so the heat exchanging air can almost completely pass through the two side end surfaces 520 , so as to avoid direct blowing to users.

Referring to FIG. 4 , when the air guide assembly is in the front air outlet state, the two air guide plates 60 can be rotated to engage with the two sides of the air outlet 142 respectively, so as to guide the heat exchange air flow out from the main body surface 510 . That is to say, the two air deflectors 60 can form an air outlet channel extending forward and backward between the air outlet 142 and the main body surface 510 by rotating, and the heat exchange airflow discharged from the air outlet 142 can be almost completely discharged along the air outlet channel. to the main body surface 510, and finally through the main body surface 510 to discharge forward into the indoor environment, so as to realize forward convergent air supply.

Referring to FIG. 5 , when the wind deflector assembly is in the state of dissipating wind, the two wind deflectors 60 can also be rotated so that one end away from the pivot axis x is in front of the air outlet 142 , and they are inclined from the rear to the front and laterally to both sides. At this time, the two air deflectors 60 are not spliced, so that part of the heat exchange air can be discharged to the indoor environment through the gap between the two air deflectors 60 and through the main body surface 510, and the other part can be discharged into the indoor environment by the two air deflectors 60. The wind panel 60 is tilted in an inclined direction and discharged into the indoor environment to the left front and right front through the junction of the main body surface 510 and the side end surface 520 respectively, so as to realize the dispersion of wind.

The two wind deflectors 60 mentioned above are controlled synchronously. In addition, the two wind deflectors 60 can also be controlled separately, and other different air outlet effects can also be realized.

Referring to FIG. 6 , in some application scenarios, the wind deflector 60 on the left side can be rotated so that its end away from the pivot axis x is in front of the air outlet 142 , while the wind deflector 60 on the right side can be rotated to be aligned with the air outlet 142 In this way, the air deflector 60 on the right prevents the heat exchange air flow from being discharged to the right, and can only be discharged forward and left.

Referring to FIG. 7 , in some application scenarios, the air deflector 60 on the right side can be rotated so that its end away from the pivot axis x is in front of the air outlet 142 , and the air deflector 60 on the left side is rotated to be in line with the air outlet 142 . In this way, the air deflector 60 on the left prevents the heat exchange air flow from being discharged to the right, and can only be discharged forward and to the right.

It can be seen that, in the cabinet type air conditioner indoor unit 1 of the present invention, since the main body surface 510 is relatively arranged in front of the air outlet front wall 14, the two side end surfaces 520 are respectively formed on the lateral ends of the main body surface 510, and are aligned with the air outlet front wall 14. The lateral edges on both sides of the wall 14 are connected, and the two wind deflectors 60 are horizontally arranged between the air outlet front wall 14 and the main body surface 510, and are in front of the air outlet 142. The two wind deflectors 60 can respectively wrap around the When the pivot axis x of the main body surface 510 rotates, when the two air deflectors 60 are spliced laterally in front of the air outlet 142 , they can block the heat exchange airflow from leaking forward, and guide part of the heat exchange airflow to pass through the two side end surfaces 520. When the two wind deflectors 60 are rotated away from each other, so that they respectively connect with the two sides of the air outlet 142, so as to guide the heat exchange air flow out from the main body surface 510, and achieve forward convergence Air supply, in short, a larger range of air supply can be achieved.

Referring to FIG. 3 , in some embodiments, the main body surface 510 defines an opening 530 in front of the air outlet 142 . The pivot axes x of the two wind deflectors 60 are respectively vertically disposed at the edges on both sides of the opening 530 . When the two air deflectors 60 are spliced laterally and are in front of the air outlet 142 , the opening 530 is closed.

The two wind deflectors 60 are also arranged so that the combined form after the two are transversely spliced is adapted to the shape and size of the opening 530, so that the two wind deflectors 60 are respectively rotated around their pivot axes x 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 arranged vertically in the lateral center of the opening 530 . When the two wind deflectors 60 are spliced laterally in front of the air outlet 142 , the ends of the two wind deflectors 60 away from the pivot axis x face the rear side of the sealing plate 540 to seal the space between the two wind deflectors 60 The gap further reduces the air volume of the heat exchange airflow discharged forward.

Referring to Fig. 4, in addition, due to the existence of the opening 530, when the two air deflectors 60 are respectively connected with the two sides of the air outlet 142, the heat exchange air can be directly discharged into the indoor environment through the formed air outlet channel, reducing the loss of wind speed .

Referring to FIG. 4 , in some embodiments, the lateral edges of the opening 530 are opposite to the front and rear edges of the air outlet 142 . Since the pivot axes x of the two wind deflectors 60 are respectively vertically arranged at the edges on both sides of the opening 530, and the edges on both sides of the opening 530 in the transverse direction are directly opposite to the edges on both sides of the air outlet 142, so when the two When the air deflector 60 is rotated to extend forward and backward, it can be connected to the two side edges of the air outlet 142 , that is to say, the formed air outlet channel is opened forward as a whole, so that the heat exchanging air can be completely discharged forward.

Referring to FIG. 4 , further, the width of the wind deflector 60 is set to be the same as the distance between the air outlet front wall 14 and the main body surface 510 . When the lateral edges of the opening 530 are facing the front and rear edges of the air outlet 142, the width of the wind 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 the wind deflector 60 The end far away from the pivot axis x can be connected to the edge of the air outlet 142, which can prevent the heat exchange air from leaking out to both sides, and further improve the effect of aggregated air supply.

In some other embodiments, in the transverse direction, the edges on both sides of the opening 530 are more outward than the edges on both sides of the air outlet 142 . That is to say, the lateral width of the opening 530 is set so that the lateral width of the air outlet 142 is larger, and the projection of the air outlet 142 to the opening 530 is inside the opening 530, so that the air outlet channel formed in this way is roughly expanded from the rear to the front. The shape can reduce the wind speed without changing the air volume.

Referring to FIG. 8 , FIG. 8 is a schematic diagram of the installation relationship between the drive mechanism and the air deflector 60 in the cabinet air conditioner indoor unit 1 according to an embodiment of the present invention. In some embodiments, the two wind deflectors 60 can be respectively driven by a set of driving mechanisms. Each driving mechanism may include a motor 72 , a driving gear 74 and a driven gear 76 . The motor 72 is fixed on the casing 10 , the driving gear 74 is fixed on the output shaft of the motor 72 , the driven gear 76 is meshed with the driving gear 74 , and the driven gear 76 is connected with the rotating shaft of the wind deflector 60 .

In some specific embodiments, the casing 10 defines an installation cavity at the top or bottom of the air outlet front wall 14, and the driving mechanism can be disposed in the installation cavity. The motor 72 is detachably fixed on the wall of the installation chamber adjacent to the air outlet front wall 14, the driving gear 74 is installed on the output shaft of the motor 72, and the driven gear 76 can be installed in the installation chamber through the rotating shaft, and is kept with the driving gear 74. Engagement, the rotating shaft of the driven gear 76 can extend through the installation cavity to the position between the air outlet front wall 14 and the main body surface 510 so as to be connected with the rotating shaft at the top or bottom of the wind deflector 60 .

Further, the diameter of the driving gear 74 is set smaller than the diameter of the driven gear 76 . That is to say, the transmission mode of the driving mechanism is that the small gear drives the large gear, so that the deceleration effect can be achieved, and the operation of the wind deflector 60 is more stable.

In some specific embodiments, the motor 72 can be set as a stepping motor 72, and the angular displacement of the stepping motor 72 can be set before leaving the factory, and the stepping motor 72 can be pre-configured before the cabinet air conditioner indoor unit 1 leaves the factory Multiple angular displacements correspond to the postures of multiple air deflectors 60 , and the user can control the stepper motor 72 through voice control/remote control, etc., to realize aggregated air supply or decentralized air supply.

Referring to FIG. 1 , in some embodiments, the casing 10 may further include an exterior wall 16 . The appearance wall 16 is configured as the appearance front wall 16 of the cabinet air conditioner indoor unit 1, which is at the forefront of the casing 10. The front of the wall surface has a side end surface 520, so the distance between the air supply wall surface and the appearance wall surface 16 can be used to accommodate the side end surface 520, so that the main body surface 510 of the air outlet grille 50 protrudes from the appearance wall surface 16, affecting the The aesthetics of the cabinet type indoor unit 1.

In some embodiments, the outline of the main body surface 510 of the air outlet grille 50 matches and is flush with the outline of the exterior front wall 16 . As shown in FIG. 9 , for example, when the appearance wall surface 16 is a forward convex arc surface, then the main body surface 510 should be configured as a forward convex arc surface. For another example, as shown in FIG. 1 and FIG. 10 , when the appearance wall surface 16 is flat, the main body surface 510 and the side end surface 520 should also be set to be flat. The above examples are only adaptive matching in some scenarios. Of course, there are other shapes of the casing 10 in actual use, and this article does not illustrate them one by one.

As shown in Figures 1 and 9, in some embodiments, the lateral width of the main body surface 510 is set to be the same as the lateral width of the air outlet front wall 14, or as shown in Figure 10, the lateral width of the main body surface 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 that of the air outlet front wall 14 , the two side end surfaces 520 can extend back and forth to connect with both sides of the air outlet front wall 14 . When the lateral width of the main body surface 510 is set to be smaller than the lateral width of the air outlet front wall 14 , the two side end surfaces 520 can extend obliquely and connect to both sides of the air outlet front wall 14 .

11, the air conditioner 1 can also include a controller 800, the controller 900 can include a processor 810 and a memory 820, the memory 920 has a machine executable program 922, when the processor 910 executes the machine executable program 822, a A method for controlling the air supply of an air conditioner 1, the control method may be based on the above-mentioned cabinet-type indoor unit. Referring to Figure 12, the air supply control method may include the following steps:

Step S910, acquire the air supply mode of the cabinet indoor unit 1, the air supply mode includes the anti-direct blowing mode and the wind following mode. The signal may be a voice signal from the user or an electrical signal transmitted through the remote controller. For example, the anti-blow mode button and the wind-following mode button are set on the remote control. When the user presses the anti-blow button, the air conditioner enters the anti-blow mode. Press the anti-blow button again to exit the automatic anti-blow mode and return to normal. Air supply logic.

Step S920, detecting the presence of users in multiple preset areas in the indoor environment where the indoor unit 1 is located. In this step, the user's position can be detected by the human body infrared sensing device disposed on the casing 10 , and the human body infrared sensing device can be disposed at the lateral center of the casing.

Step S930, control the air guide assembly to adjust the air supply direction of the heat exchange airflow according to the air supply mode and the presence of the situation, so that in the anti-direct blowing mode, the air supply to the preset area where there are users is stopped to realize the anti-direct blowing function, or In the wind following mode, the wind is sent to the preset area where the user exists to realize the anti-direct blowing function.

As can be seen from the above analysis, since the main body surface 510 of the air outlet grille 50 is arranged facing the front of the air outlet front wall 14, the two side end surfaces 520 are respectively formed on the lateral ends of the main body surface 510, and are connected to the air outlet front wall 14. The edges on both sides of the horizontal side are connected, that is, the outlet grille where the heat exchange airflow is discharged from multiple air supply directions. The air guide assembly can realize various air outlet modes through the rotation of the two air guide plates 60 , therefore, the air guide assembly can be used to adjust the air supply direction, thereby realizing the function of preventing direct blowing and following the wind.

In conjunction with Fig. 5, further, a plurality of preset areas are set to be divided into three preset areas according to the extension direction of the two wind deflectors 60 in the scattered wind state, and the three preset areas are respectively located in the wind deflector of Daoge. A first area between the extension directions and a second area and a third area respectively on the left and right of the first area.

Referring to FIG. 3 , in some embodiments, when in the anti-direct blowing mode, when it is detected that there is a user in the first area, the two wind deflectors 60 are urged to rotate close to each other, so that they are horizontally spliced at the air outlet 142, to prevent the heat exchange airflow from penetrating forward into the first area, and guide the heat exchange airflow to the left front and right front to penetrate into the second area and the third area respectively, that is, to switch the air guide assembly to the two sides. wind state.

In some embodiments, when it is detected that there is a user in the second area, the wind deflector 60 close to the second area is rotated to engage with the edge of the corresponding air outlet 142 to prevent the heat exchange airflow from being exhausted to the second area.

That is to say, when it is detected that there is a user in the second area, the wind deflector 60 close to the second area can only be rotated to engage with the edge of the corresponding air outlet 142, so as to prevent the heat exchange air flow from being discharged to the second area, and in addition A wind deflector 60 can be determined according to specific conditions. As shown in Figure 4, for example, when there are users in the second area, there are also users in the third area, then the wind deflector 60 close to the third area can be rotated to engage with the edge of the corresponding air outlet 142, that is, to deflect the wind. The component switches to the front air outlet state. As shown in FIG. 7 , for example, when there are users in the second area and there are no users in the third area, the wind deflector 60 close to the third area can be rotated to extend from the rear to the front and outwards to realize simultaneous Wind forward and towards the third zone.

In some embodiments, when it is detected that there is a user in the third area, the wind deflector 60 close to the third area is rotated to engage with the edge of the corresponding air outlet 142 so as to prevent the heat exchanging air from being exhausted to the third area.

Similar to the above embodiment, when it is detected that there is a user in the third area, the wind deflector 60 close to the third area can only be rotated to engage with the edge of the corresponding air outlet 142, so as to prevent the heat exchange air from being exhausted to the second area , while the other wind deflector 60 can be determined according to specific conditions.

Referring to FIG. 5 , in some embodiments, when it is detected that there are no users in any of the areas, the air guide assembly is controlled to switch to the diffused state, so as to blow air to three preset areas at the same time.
