Referring to fig. 4, furthermore, the lateral width from the edge of the air outlet front wall 14 to the edge of the air outlet 142 is set to be not smaller than the width of the second air deflector 62. That is, the lateral distance between the two sides of the air outlet 142 is sufficient to fully expand the second air deflector 62 to completely avoid the passage between the air outlet 142 and the lateral end surface 520.
Referring to fig. 4, in some usage scenarios, the two first air deflectors 60 are in a closed position, and the two second air deflectors 62 are rotated to be respectively attached to the air outlet front wall 14, so that the first air deflectors 60 and the enclosed area 514 are utilized to guide the heat exchange air flow to be discharged through the side end face 520.
That is, in this scenario, the two first air deflectors 60 translate to a combined configuration of transverse splicing to enclose the ventilation zone 512, such that the overall body face 510 is enclosed by the two first air deflectors 60 and the two enclosed zones 514, and the heat exchange air flow cannot pass forward. Each of the second air deflection plates 62 is attached to the front surface of the air outlet front wall 14 after being rotated 180 ° in a state of closing the air outlet 142, so that the heat exchange air flow discharged from the air outlet 142 can be discharged forward to the main body surface 510. Because the main body surface 510 is totally enclosed, two sides of the main body surface 510 are two side end surfaces 520 for ventilation, so that the heat exchange air flow discharged from the air outlet 142 is discharged forward to the rear of the main body surface 510, and then is guided by the first air deflector 60 and the enclosed area 514 transversely and then is discharged from the two side end surfaces 520 respectively, thereby realizing two-side air outlet and avoiding direct blowing users.
In some usage scenarios, the two first air deflectors 60 are in an open position and the at least one second air deflector 62 is rotated such that an end distal from the pivot axis is behind the ventilation zone 512 to direct the flow of heat exchange air out of the ventilation zone 512.
Referring to fig. 5, in some specific usage scenarios, the two first air deflectors 60 are in the open position, and the two second air deflectors 62 are rotated such that the ends of the two second air deflectors, which are far away from the pivot axis, are located behind the ventilation area 512, so that an air outlet channel extending approximately forwards and backwards is formed between the air outlet 142 and the ventilation area 512 by rotation of the two second air deflectors 62, and the heat exchange air flow discharged from the air outlet 142 can be almost completely discharged to the ventilation area 512 along the air outlet channel, and finally discharged forwards to the indoor environment through the ventilation area 512, so that forward aggregation air supply can be achieved.
Referring to fig. 6, in some other use scenarios, when the two first air deflectors 60 are in the open position, the right second air deflector 62 rotates such that the end away from the pivot axis is behind the ventilation zone 512, and the left second air deflector 62 rotates to be attached to the air outlet front wall 14, so that a portion of the heat exchange air flow discharged from the air outlet 142 is discharged forward from the ventilation zone 512 into the indoor environment under the guidance of the right second air deflector 62, and another portion can be discharged to the left side end face 520 under the guidance of the left closed zone 514, and then discharged into the indoor environment through the left side end face 520, thereby achieving forward and leftward air outflow, avoiding direct blowing of users on the right side.
Referring to fig. 7, of course, in some other use scenarios, when the two first air deflectors 60 are in the open position, the left second air deflector 62 rotates such that the end away from the pivot axis is behind the ventilation zone 512, while the right second air deflector 62 rotates to attach to the ventilation front wall 14, enabling forward and rightward ventilation, avoiding direct blowing of the user on the left.
It can be seen that, in the cabinet air-conditioning indoor unit 1 of the present invention, the adjustment of the two first air deflectors 60 and the two second air deflectors 62 can realize at least four modes of preventing direct air blowing, namely: two sides of the air outlet without front air outlet (the straight-blowing preventing front user shown in fig. 4), two sides of the air outlet with front air outlet (the straight-blowing preventing left and right users simultaneously shown in fig. 5), two sides of the air outlet with front and left air outlet without right air outlet (the straight-blowing preventing right user shown in fig. 6), two sides of the air outlet with front and right air outlet without right air outlet (the straight-blowing preventing left user shown in fig. 7).
Referring to fig. 8, in some embodiments, the lateral width of the ventilation area 512 is set to be the same as the lateral width of the air outlet 142, the ventilation area 512 is aligned front to back with the air outlet 142, and the width of each second air deflector 62 is set to be the same as the spacing between the main body face 510 and the air outlet front wall 14.
That is, since the second air deflectors 62 rotate around the two side edges adjacent to the air outlet 142, by the above limitation, when the air is blown forward, the two second air deflectors 62 can make their ends far away from the pivot shaft abut against the lateral two side edges of the ventilation area 512 by rotating, so that the air outlet channel is almost sealed, the heat exchange air flow cannot penetrate from two sides, and the effect of the aggregate air supply is further improved.
Referring to FIG. 5, in other embodiments, the orthographic projection of the air outlet 142 to the ventilation area 512 is inside the ventilation area 512. In this embodiment, the width of the second air deflector 62 may be set to be the same as the distance between the main body surface 510 and the air outlet front wall 14. In this embodiment, if a sealed air outlet passage is desired, the second air deflection 62 needs to extend back and forth so that the end of the second air deflection 62 remote from the pivot axis needs to abut against the rear surface of the air permeable region 512. If one end of the two second air deflectors 62 far from the pivot shaft is abutted against two lateral side edges of the ventilation area 512, the front end of the resultant air outlet passage may leak air to two sides, but basically the effect of converging the air supply forward can be achieved.
Referring to fig. 9, in some embodiments, two first air deflectors 60 may each be driven by a set of first drive mechanisms. Each set of first driving mechanism may include a first motor 710, a transmission gear 712, and a rack 714, where the first motor 710 is fixed on the housing 10, the transmission gear 712 is fixed on an output shaft of the first motor 710, the transmission gear 712 is meshed with the rack 714, and the rack 714 is disposed along a width direction of the first air deflector 60.
In some embodiments, the housing 10 defines a mounting cavity at the top or bottom of the air outlet front wall 14, and the first drive mechanism may be disposed within the mounting cavity. The first motor 710 is detachably fixed on the wall of the mounting cavity adjacent to the air outlet front wall 14, the transmission gear 712 is arranged in the mounting cavity and is mounted on the output shaft of the first motor 710, and the rack 714 can be directly formed on the first air deflector 60 or mounted on the first air deflector 60 through a connecting piece, and when the first motor 710 rotates, the rack 714 is driven to translate through the transmission gear 712, so that the first air deflector 60 is controlled to translate.
Referring to fig. 10, in some embodiments, two second air deflectors 62 may each be driven by a set of second drive mechanisms. Each set of second drive mechanisms may include a second motor 720, a driving gear 722, and a driven gear 724. The motor 72 is fixed to the housing 10, the driving gear 722 is fixed to an output shaft of the motor 72, the driven gear 724 is meshed with the driving gear 722, and the driven gear 724 is connected with a rotating shaft of the second air deflector 62.
In some embodiments, the first motor 710 and the second motor 720 are both removably secured to the wall of the mounting cavity adjacent the air outlet front wall 14, the drive gear 722 is mounted to the output shaft of the motor 72, the driven gear 724 is rotatably mounted within the mounting cavity and is held in engagement with the drive gear 722, and the rotation shaft of the driven gear 724 extends through the mounting cavity to a position between the air outlet front wall 14 and the main body surface 510 for connection to the rotation shaft of the top or bottom of the second air deflector 62.
Further, the diameter of the driving gear 722 is set smaller than the diameter of the driven gear 724. That is, the driving mechanism drives the pinion to drive the bull gear, so that a deceleration effect can be realized, and the air deflector 60 operates more stably.
In some specific embodiments, the first motor 710 and the second motor 720 may be configured as a stepper motor, and angular displacement of the stepper motor may be set before the cabinet air-conditioning indoor unit 1 is shipped, and the stepper motor may be preconfigured with a plurality of angular displacements before the cabinet air-conditioning indoor unit is shipped, and a user may control the stepper motor through a voice control/remote controller or the like, so as to further implement aggregate air supply or distributed air supply.
Referring to fig. 1, in some embodiments, the housing 10 may also include an exterior wall 16. 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. 11, 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 12, 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, the lateral width of the body face 510 is set to be the same as the lateral width of the outlet front wall 14, as shown in fig. 1, 11, or the lateral width of the body face 510 is set to be less than the lateral width of the outlet front wall 14, as shown in fig. 12.
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. 13, 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 having a machine executable program 922, and a method of controlling air supply of the air conditioner 1 may be implemented when the processor 910 executes the machine executable program 822. Referring to fig. 14, the air supply control method may include the steps of:
step S910, a signal for starting the blow-through preventing mode is received from the user. The signal may be a voice signal from a user or an electrical signal transmitted through a remote control. For example, a button of a direct blowing prevention mode is arranged on the remote controller, when a user presses the button of the direct blowing prevention mode, the air conditioner enters the direct blowing prevention mode, presses the button of the direct blowing prevention mode again, exits the automatic direct blowing prevention mode, and resumes normal air supply logic.
In step S920, the presence of the user in three preset areas in the indoor environment where the indoor unit is located is detected, wherein the three preset areas are respectively a front area, a left area and a right area of the indoor unit 1 of the cabinet air conditioner. In this step, the user position can be detected by the human body infrared sensing device provided on the casing 10.
In step S930, the first air deflector 60 and the second air deflector 62 are controlled according to the existence condition to adjust the air supply direction of the heat exchange air flow, so as to stop the air supply to the preset area where the user exists, thereby realizing the direct blowing prevention function. For example, when a user is present in the front area, the air supply to the front area may be stopped, when a user is present in the left area, the air supply to the left area may be stopped, and when a user is present in the right area, the air supply to the right area may be stopped, thereby realizing the blow-out preventing function.
Specifically, when a user is detected to be present in the front area, the two first air deflectors 60 are caused to translate to the closed position to shut off the path of the air blown to the front area. In this scenario, the two second air deflectors 62 may be respectively rotated to be attached to the air outlet front wall 14, so as to guide the heat exchange air flow to be discharged through the two side end surfaces 520 by using the first air deflectors 60 and the enclosed area 514.
When a user is detected in the left area, the two first air deflectors 60 are caused to translate to the open position, causing the second air deflector 62 near the left area to rotate such that the end remote from the pivot axis is rearward of the ventilation area 512 to shut off the path of the left area air supply. In this scenario, the second air deflector 62 far from the left area may be attached to the air outlet front wall 14 to supply air to the front area and the right area at the same time, or may be turned such that the end far from the pivot shaft is located behind the ventilation area 512 to only supply air to the front area.
When a user is detected in the right area, the two first air deflectors 60 are caused to translate to the open position, causing the second air deflector 62 near the right area to rotate such that the end remote from the pivot axis is behind the ventilation area 512 to shut off the path of the right area air supply. In this scenario, the second air deflector 62 far from the right side area may be attached to the air outlet front wall 14 to supply air to the front area and the left side area at the same time, or may be turned such that one end far from the pivot shaft is located at the rear of the ventilation area 512 to only supply air to the front area.
In some embodiments, when no user is detected in any of the areas, the two first air deflectors 60 are caused to translate to the open position and the two second air deflectors 62 are caused to be respectively affixed to the outlet front wall 14 to simultaneously supply air in the front, left, and right areas.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
