[0032] In the description of this embodiment, it should be understood that the terms "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," and "depth," etc., indicate the orientation or positional relationship based on the orientation of the indoor unit 1 of the cabinet air conditioner under normal use, and can be determined with reference to the orientation or positional relationship shown in the accompanying drawings. For example, "front" in indicating orientation refers to the side facing the user. This is only for the convenience of describing the present invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0033] This invention first provides an air conditioner, which generally includes an indoor unit installed indoors and an outdoor unit installed outdoors. The air conditioner utilizes a circulating refrigeration system to achieve cooling or heating. This system uses a refrigerant in a compression phase-change cycle through a compressor, an outdoor unit heat exchanger, an indoor unit heat exchanger, and a throttling device to transfer heat. In the air conditioner, the refrigeration system can also be equipped with a reversing valve to change the direction of refrigerant flow, causing the indoor unit heat exchanger to alternately act as an evaporator or condenser to achieve cooling or heating functions. Since the circulating refrigeration system in air conditioners is well known to those skilled in the art, its working principle and structure will not be described in detail here.

[0034] See Figures 1 to 5 In some embodiments, the present application also provides a cabinet type indoor unit capable of blowing air from both sides to avoid direct blowing to the user. The cabinet type air conditioner indoor unit 1 can further include a casing 10, an air duct framework 20, and a cross-flow fan 40.

[0035] The casing 10 protects the entire cabinet type air conditioner indoor unit 1, and the rear side of the casing 10 is provided with an air inlet grille 12 having a heat exchange air inlet formed thereon, and the front side of the casing 10 is provided with an air outlet 142.

[0036] The air duct framework 20 is arranged inside the casing 10, and the air duct framework 20 is formed with a heat exchange air duct 222, and the heat exchange air duct 222 has an air inlet side open to the heat exchange air inlet and an air outlet side facing the air outlet 142. The air duct framework 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 leaves 226 can be arranged in the air outlet air duct 224 to adjust the direction of the heat exchange air flow by swinging up and down.

[0037] The evaporator 30 is mounted on the air duct framework 20 and covers the heat exchange air duct 222 to exchange heat with the air drawn into the casing 10 from the heat exchange air inlet, and the heat exchanged air is discharged into the room through the air outlet side of the air duct framework 20 and the air outlet 142 of the casing 10 to achieve cooling or heating.

[0038] The cross-flow fan 40 is mounted in the heat exchange air duct 222 in the transverse direction to facilitate the indoor air flow from the heat exchange air inlet into the casing 10 to exchange heat with the evaporator 30 and finally discharged from the air outlet 142.

[0039] In some embodiments, the casing 10 further has an air outlet front wall 14, and the air outlet 142 is arranged in the transverse middle part of the air outlet front wall 14, and the air outlet 142 can be in the shape of a long strip extending in the height direction of the casing 10 to make full use of the shape of the casing 10 to obtain a larger air outlet area.

[0040] The indoor unit 1 of the cabinet-type air conditioner can further include an air outlet grille 50 and an air guide assembly. The air outlet grille 50 can be provided with air-permeable holes for allowing the heat exchange airflow discharged from the air outlet 142 to pass through. The air outlet grille 50 has a main body surface 510 and two side end surfaces 520. The main body surface 510 is arranged in front of the air outlet front wall 14, and the two side end surfaces 520 are formed at the two ends of the main body surface 510 in the transverse direction and are connected to the two side edges of the air outlet front wall 14. The air guide assembly includes two air guide plates 60 arranged in the transverse direction between the air outlet front wall 14 and the main body surface 510 in front of the air outlet 142. The two air guide plates 60 are configured to rotate around the main body surface 510. The air guide assembly can achieve different air outlet effects by rotating the two air guide plates 60. Specifically, the air guide assembly can have at least a two-side air outlet state, a front air outlet state, and a scattered air outlet state.

[0041] Referring to Figure 3 When the air guide assembly is in the two-side air outlet state, the two air guide plates 60 can be rotated towards each other to be arranged in front of the air outlet 142 in the transverse direction to block the heat exchange airflow from being discharged forwardly. The two air guide plates 60 arranged in the transverse direction can guide part of the heat exchange airflow to be discharged through the two side end surfaces 520 to avoid directly blowing the user in front of the cabinet 10.

[0042] It should be noted that in this state, although the two air guide plates 60 do not completely block the main body surface 510, since the two air guide plates 60 are arranged in front of the air outlet 142 in the transverse direction, the heat exchange airflow discharged from the air outlet 142 will first be guided in the transverse direction by the two air guide plates 60. Therefore, the heat exchange airflow can be almost completely discharged through the two side end surfaces 520 to avoid directly blowing the user.

[0043] Referring to Figure 4 When the air guide assembly is in the front air outlet state, the two air guide plates 60 can be rotated to be connected to the two sides of the air outlet 142, respectively, to guide the heat exchange airflow to be discharged from the main body surface 510. That is, by rotating the two air guide plates 60, an air outlet channel extending in the front-rear direction can be formed between the air outlet 142 and the main body surface 510. 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 discharged forwardly through the main body surface 510 to the indoor environment. In this way, the front aggregated air supply can be achieved.

[0044] Referring to Figure 5When the air guide assembly is in the air dispersion state, the two air guide plates 60 can also be rotated to be in front of the air outlet 142 at the end away from the pivot shaft x and extend obliquely from back to front and to the lateral sides, at this time the two air guide plates 60 are not spliced, so that part of the heat exchange airflow can be discharged forward and through the main body surface 510 to the indoor environment through the gap between the two air guide plates 60, and the other part can be discharged to the indoor environment through the main body surface 510 and the side end surface 520 combined with the oblique direction of the two air guide plates 60 to the left front and right front respectively, to realize dispersed air outlet.

[0045] The above-mentioned two air guide plates 60 are synchronously controlled, in addition, the two air guide plates 60 can also be controlled respectively, and other different air outlet effects can also be realized.

[0046] Referring to Figure 6 In some application scenarios, the left air guide plate 60 can be rotated to be in front of the air outlet 142 at the end away from the pivot shaft x, and the right air guide plate 60 is rotated to be connected with the air outlet 142, so that the right air guide plate 60 blocks the heat exchange airflow to the right and can only be discharged forward and to the left.

[0047] Referring to Figure 7 In some application scenarios, the right air guide plate 60 can be rotated to be in front of the air outlet 142 at the end away from the pivot shaft x, and the left air guide plate 60 is rotated to be connected with the air outlet 142, so that the left air guide plate 60 blocks the heat exchange airflow to the right and can only be discharged forward and to the right.

[0048] Therefore, the cabinet type air conditioner indoor unit 1 of the present application, since the main body surface 510 is arranged in front of the air outlet front wall 14, the two side end surfaces 520 are respectively formed at the lateral two ends of the main body surface 510 and connected with the lateral two side edges of the air outlet front wall 14, the two air guide plates 60 are arranged between the air outlet front wall 14 and the main body surface 510 in the lateral direction and in front of the air outlet 142, and the two air guide plates 60 can be rotated around the pivot shaft x close to the main body surface 510, when the two air guide plates 60 are spliced in the lateral direction in front of the air outlet 142, the heat exchange airflow can be blocked from being discharged forward and guided to be discharged through the two side end surfaces 520, to realize dispersed air outlet, when the two air guide plates 60 are rotated away from each other to be connected with the two sides of the air outlet 142 respectively, to guide the heat exchange airflow to be discharged from the main body surface 510, to realize forward aggregated air supply, in short, a large range of air supply can be realized.

[0049] Referring to Figure 3In some embodiments, the main body surface 510 is provided with an opening 530 in front of the air outlet 142. The pivot axes x of the two air deflectors 60 are respectively arranged at the edges of the opening 530 in the vertical direction. When the two air deflectors 60 are horizontally spliced in front of the air outlet 142, the opening 530 is closed.

[0050] The two air deflectors 60 are also arranged to match the shape and size of the opening 530 in the combined state after being horizontally spliced. When the two air deflectors 60 are rotated around the pivot axes x to be horizontally spliced at the opening 530, the opening 530 can be completely closed.

[0051] Referring to Figure 3 Further, the transverse center of the opening 530 is provided with a sealing plate 540 in the vertical direction. When the two air deflectors 60 are horizontally spliced in front of the air outlet 142, the ends of the two air deflectors 60 away from the pivot axes x are both faced to the back side of the sealing plate 540 to seal the gap between the two air deflectors 60, further reducing the air volume of the heat exchange airflow discharged forward.

[0052] Referring to Figure 4 In addition, due to the presence of the opening 530, when the two air deflectors 60 are connected to the two sides of the air outlet 142, the heat exchange airflow can be directly discharged to the indoor environment through the formed air outlet channel, reducing the loss of air speed.

[0053] Referring to Figure 4 In some embodiments, the edges of the opening 530 on the transverse sides are opposite to the edges of the air outlet 142 in front and back. Since the pivot axes x of the two air deflectors 60 are respectively arranged at the edges of the opening 530 in the vertical direction, and the edges of the opening 530 on the transverse sides are opposite to the edges of the air outlet 142 in front and back, when the two air deflectors 60 are rotated to extend forward and backward, they can be connected to the edges of the air outlet 142, that is, the formed air outlet channel is entirely open forward to facilitate the heat exchange airflow to be completely discharged forward.

[0054] Referring to Figure 4 Further, the width of the air deflector 60 is arranged to be the same as the distance between the air outlet front wall 14 and the main body surface 510. In the case that the edges of the opening 530 on the transverse sides are opposite to the edges of the air outlet 142 in front and back, the width of the air deflector 60 is arranged to be the same as the distance between the air outlet front wall 14 and the main body surface 510, and the end of the air deflector 60 away from the pivot axis x can be connected to the edge of the air outlet 142, which can prevent the heat exchange airflow from leaking to the sides, further improving the effect of the concentrated air supply.

[0055] In some other embodiments, in the lateral direction, the edges of the two sides of the opening 530 are further outward than the edges of the two sides of the air outlet 142. That is, the lateral width of the opening 530 is set to be greater than the lateral width of the air outlet 142, and the projection of the air outlet 142 on the opening 530 is inside the opening 530, so that the air outlet channel formed thereby is substantially in the shape of a gradually expanding cone from back to front, achieving the effect of reducing the air speed while keeping the air volume unchanged.

[0056] Referring to Figure 8 , Figure 8 FIG. 1 is a schematic view of the installation relationship between the driving mechanism and the air deflector 60 in the cabinet air conditioner indoor unit 1 according to an embodiment of the present application. In some embodiments, two air deflectors 60 can be driven by a set of driving mechanisms respectively. Each set of driving mechanisms can include a motor 72, a driving gear 74 and a driven gear 76. The motor 72 is fixed to the cabinet 10, the driving gear 74 is fixed to the output shaft of the motor 72, and the driven gear 76 is connected to the rotating shaft of the air deflector 60 and engaged with the driving gear 74.

[0057] In some specific embodiments, the cabinet 10 defines a mounting cavity at the top or bottom of the air outlet front wall 14, and the driving mechanism can be arranged in the mounting cavity. The motor 72 is detachably fixed to the wall of the mounting cavity adjacent to the air outlet front wall 14, the driving gear 74 is mounted on the output shaft of the motor 72, and the driven gear 76 is mounted in the mounting cavity through a rotating shaft and engaged with the driving gear 74. The rotating shaft of the driven gear 76 can extend into the position between the air outlet front wall 14 and the main body surface 510 so as to be connected to the rotating shaft of the top or bottom of the air deflector 60.

[0058] Further, the diameter of the driving gear 74 is set to be smaller than the diameter of the driven gear 76. That is, the driving mechanism is in the mode of a small gear driving a large gear, so that the speed reduction effect can be achieved, and the operation of the air deflector 60 is more stable.

[0059] In some specific embodiments, the motor 72 can be a stepping motor 72, and the angular displacement of the stepping motor 72 can be set before delivery. The stepping motor 72 can be pre-configured with multiple angular displacements before delivery of the cabinet air conditioner indoor unit 1, so as to correspond to multiple postures of the air deflector 60 respectively. The user can control the stepping motor 72 through voice control / remote controller and other means, so as to achieve the effects of convergent air supply or divergent air supply.

[0060] Referring to Figure 1In some embodiments, the cabinet 10 can further include an appearance wall 16. The appearance wall 16 is configured as the appearance front wall of the cabinet 10, which is located at the frontmost position of the cabinet 10. The air supply wall can be arranged to be more rearward than the appearance wall 16. Since the air supply grille is arranged 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 to accommodate the side end surface 520. In this way, the main body surface 510 of the air supply grille 50 can protrude from the appearance wall 16, which affects the aesthetics of the cabinet 1.

[0061] In some embodiments, the main body surface 510 of the air supply grille 50 is contoured and flush with the contour of the appearance front wall 16. As shown in Figure 9 , for example, when the appearance wall 16 is a front convex arc surface, the main body surface 510 should be arranged as a front convex arc surface. For another example, as shown in Figure 1 , Figure 10 , when the appearance wall 16 is a flat surface, the main body surface 510 and the side end surface 520 should also be arranged as flat surfaces. The above examples are only adaptive collocations in some scenarios. Of course, there are other shapes of cabinets 10 in actual use, which are not illustrated one by one herein.

[0062] As shown in Figure 1 , Figure 9 , in some embodiments, the transverse width of the main body surface 510 is arranged to be the same as the transverse width of the air supply front wall 14, or as shown in Figure 10 , the transverse width of the main body surface 510 is arranged to be smaller than the transverse width of the air supply front wall 14.

[0063] When the transverse width of the main body surface 510 is arranged to be the same as the transverse width of the air supply front wall 14, the two side end surfaces 520 can be extended forward and backward to connect the two sides of the air supply front wall 14. When the transverse width of the main body surface 510 is arranged to be smaller than the transverse width of the air supply front wall 14, the two side end surfaces 520 can be extended obliquely to connect the two sides of the air supply front wall 14.

[0064] Referring to Figure 11 , the air conditioner 1 can further include a controller 800. The controller 900 can include a processor 810 and a memory 820. The memory 820 has a machine executable program 822. When the processor 910 executes the machine executable program 822, an air supply control method of an air conditioner 1 can be implemented. The control method can be based on the cabinet 1 described above. Referring to Figure 12 , the air supply control method can include the following steps:

[0065] Step S910, obtaining the air supply mode of the cabinet indoor unit 1, the air supply mode including the anti-direct blowing mode and the wind following mode. The signal can be a voice signal from the user or an electrical signal transmitted through the remote controller. For example, the anti-direct blowing mode button and the wind following mode button are arranged on the remote controller, when the user presses the anti-direct blowing button, the air conditioner enters the anti-direct blowing mode, and presses the anti-direct blowing button again, the automatic anti-direct blowing mode is exited, and the normal air supply logic is restored.

[0066] Step S920, detecting the presence of the user in the multiple preset areas in the indoor environment where the indoor unit 1 is located. In this step, the user position can be detected by the human body infrared sensing device arranged on the cabinet 10, and the human body infrared sensing device can be arranged on the transverse center of the cabinet.

[0067] Step S930, controlling the air guide assembly to adjust the air supply direction of the heat exchange airflow according to the air supply mode and the presence, so that in the anti-direct blowing mode, the air supply to the preset area where the user is present is stopped to realize the anti-direct blowing function, or in the wind following mode, the air supply to the preset area where the user is present is performed to realize the anti-direct blowing function.

[0068] From the above analysis, since the main surface 510 of the air outlet grille 50 is arranged in front of the air outlet front wall 14, and the two side end surfaces 520 are formed at the transverse two ends of the main surface 510 and are connected with the transverse two side edges of the air outlet front wall 14, that is, the air outlet grille through which the heat exchange airflow is discharged from multiple air supply directions. The air guide assembly can realize multiple air outlet modes through the rotation of the two air guide plates 60, so that the air supply direction can be adjusted by using the air guide assembly, and the anti-direct blowing function and the wind following function can be realized.

[0069] In combination Figure 5 Further, the multiple preset areas are arranged to be divided into three preset areas according to the extension directions of the two air guide plates 60 in the air scattering state, and the three preset areas are respectively a first area between the extension directions of the two air guide plates and a second area and a third area respectively on the left side and the right side of the first area.

[0070] In combination Figure 3 In some embodiments, when it is detected that the user is present in the first area in the anti-direct blowing mode, the two air guide plates 60 are caused to rotate towards each other so as to be transversely spliced in front of the air outlet 142, so as to block the heat exchange airflow from penetrating into the first area, and guide the heat exchange airflow to penetrate into the second area and the third area respectively to the left front and the right front, that is, the air guide assembly is switched to the two-side air outlet state.

[0071] In some embodiments, when it is detected that the user is present in the second area, the air guide plate 60 close to the second area is caused to rotate to be connected with the edge of the corresponding air outlet 142, so as to block the heat exchange airflow from being discharged to the second area.

[0072] That is, when it is detected that the second area has a user, only the register 60 close to the second area can be rotated to abut the edge of the corresponding air outlet 142 to block the heat exchange airflow from being discharged to the second area, and the other register 60 can be determined according to the specific situation. For example, as shown in FIG. 6, when the second area has a user and the third area also has a user, the register 60 close to the third area can be rotated to abut the edge of the corresponding air outlet 142, that is, the register assembly is switched to the front air outlet state. Figure 4 Figure 7 For another example, as shown in FIG. 7, when the second area has a user and the third area does not have a user, the register 60 close to the third area can be rotated to extend from the back to the front and outward, so as to realize air outlet to the front and the third area at the same time.
