In some embodiments, as shown in fig. 4 and 5, a bypass housing 300 is mounted on the right side plate 101 of the casing 100. The plate surface of the right side plate 101 located in the rear space is provided with a communication port 102, or the plate surface of the right side plate 101 located in the front space is provided with a communication port 102. The bypass housing 300 is provided with a bypass air inlet and a bypass air outlet, and the bypass air outlet is in butt joint with the communication port 102. A bypass fan 310 is disposed in the bypass casing 300, and the bypass fan 310 is used for blowing the air in the bypass casing 300 into the cabinet 100. In addition, an on-off assembly 320 is disposed in the casing 100, and the on-off assembly 320 is used for opening or blocking the air intake from the bypass casing 300 to the casing 100.

In this embodiment, when the user has a demand for rapid cooling or rapid heating, the on-off assembly 320 opens the air that bypasses the housing 300 to the cabinet 100. Indoor air enters the bypass casing 300 from the bypass air inlet, and the air in the bypass casing 300 enters the casing 100 through the bypass air outlet under the action of the bypass ventilator 310, so that the air inlet volume of the casing 100 is effectively increased, and the circulation rate of the indoor air is improved. When the user does not have the requirement for quick cooling or quick heating, the on-off component 320 blocks the air from the bypass casing 300 to the casing 100, so that the air in the casing 100 can be blocked from entering the bypass casing 300 from the communication port 102, the air exchanging heat between the inside of the casing 100 and the heat exchange component is prevented from being reduced, and the conventional cooling or heating capacity of the indoor unit is ensured.

Alternatively, the periphery of the exhaust outlet of the bypass fan 310 is provided with a connecting flange, the connecting flange can be fixed on the side plate of the bypass housing 300 provided with the bypass air outlet by using a bolt fastener, and the exhaust outlet and the bypass air outlet are butted.

Alternatively, the casing 100 is configured in a rectangular parallelepiped shape, and the bypass casing 300 is also configured in a rectangular parallelepiped shape. Therefore, after the bypass casing 300 is connected to the casing 100, the appearance of the indoor unit after the bypass casing 300 is newly added does not cause a sharp feeling to a user.

Alternatively, the bypass housing 300 is detachably connected to the right side plate 101 of the cabinet 100. Thus, the bypass housing 300 serves as a separate installation module, and the user selectively installs the bypass housing 300 according to the layout of the finished space and the use requirement.

Illustratively, two sliding blocks are disposed on the right side plate 101 of the bypass housing 300, and two sliding rails are respectively located at two sides of the bypass air outlet. Two sliding rails are arranged on the side plate of the casing 100, which is provided with the communication port 102, and the two sliding rails respectively correspond to the two sliding blocks. When the bypass casing 300 is mounted, the slider is slid into the corresponding slide rail from below, the bypass air outlet is abutted against the communication opening 102, and then the slider is fixed to the slide rail by using the bolt fastener, so that the bypass casing 300 is attached to the right side plate 101 of the cabinet 100.

In some embodiments, the on/off assembly 320 includes a roller shade and two roller tubes. Wherein, the two reels are respectively arranged at two sides of the communication opening 102 of the casing 100; two ends of the roller shutter are respectively wound on the two winding shafts; the curtain surface of the roller shutter is provided with an avoidance opening, and the roller shutter is wound between two winding shafts; when the rolling shutter is wound to the position where the escape opening corresponds to the communication opening 102, the rolling shutter is used for opening the air intake from the bypass casing 300 to the housing 100, and when the rolling shutter is wound to the position where the escape opening is completely dislocated from the communication opening 102, that is, the curtain surface of the rolling shutter completely blocks the communication opening 102, so as to block the air intake from the bypass casing 300 to the housing 100.

In this embodiment, under the condition that the user does not have the demand for quick cooling or quick heating, the roller shutter is wound to the position completely blocking the communication port 102, and at this time, the curtain surface of the roller shutter blocks the air entering from the bypass casing 300 to the casing 100, so that the air in the casing 100 can be blocked from entering the bypass casing 300 from the communication port 102, thereby avoiding reducing the air in the casing 100 and exchanging heat with the heat exchange component, and ensuring the conventional cooling or heating capability of the indoor unit. Under the condition that a user has a requirement for quick cooling or quick heating, the roller shutter is wound to a position corresponding to the avoidance port and the communication port 102, and at the moment, the roller shutter opens the bypass casing 300 to supply air to the casing 100, so that the air inlet amount of the casing 100 can be increased under the action of the bypass ventilator 310, and the circulation rate of indoor air is increased.

Alternatively, the avoidance port on the curtain surface of the roll screen is greater than or equal to the communication port 102 of the right side plate 101, and the curtain surface shifts between positions of completely blocking the communication port 102, partially blocking the communication port 102, and completely avoiding the communication port 102 as the roll screen is wound back and forth between the two winding shafts. When the roller shutter is completely retracted from the position of the communication port 102, the amount of air taken into the housing 100 by the bypass case 300 is maximized. In the case of the position where the shutter completely blocks the communication port 102, the amount of air taken into the cabinet 100 by the bypass case 300 is zero.

Optionally, the on-off assembly 320 further includes two drive motors. The two driving motors are respectively connected to a reel through a transmission component so as to drive the corresponding reels to rotate. The user can adjust the position of the escape opening of the roll screen relative to the communication opening 102 of the housing 100 by controlling the two driving motors.

Illustratively, the two winding shafts are a first winding shaft and a second winding shaft respectively, and the avoidance port is completely wound on the second winding shaft when the roller shutter is in the initial position, namely, the curtain surface of the roller shutter completely blocks the communication port 102 in the initial position. When the driving motor corresponding to the first reel is started, the first reel winds up the curtain surface, the avoiding opening gradually corresponds to the communication opening 102, and the curtain surface of the roller curtain completely avoids the communication opening 102 when the avoiding opening and the communication opening completely correspond to each other. Then, when the driving motor corresponding to the second winding shaft is started, the second winding shaft winds the curtain surface, the avoidance ports are gradually and completely wound on the second winding shaft, the avoidance ports are staggered with the communication port 102, and when the avoidance ports are completely staggered with the communication port 102, the curtain surface of the rolling curtain completely shields the communication port 102. In this way, the position of the avoidance opening can be effectively adjusted by controlling the starting and stopping of the driving motor, for example, the roller shutter is adjusted to the position for shielding the 1/4 communication opening 102, or the roller shutter is adjusted to the position for shielding the 1/2 communication opening 102.

Optionally, the indoor unit further comprises a wind speed detector. The wind speed detector is used for detecting the air intake of the bypass casing 300 to the enclosure 100, and the wind speed detector and the two driving motors are electrically connected to the air conditioner controller, so that the position of the roller shutter relative to the communication port 102 can be regulated according to the air intake.

Illustratively, the amount of air supplied to the cabinet 100 by the bypass housing 300 is too large, and the air speed detector sends an air speed signal to the air conditioner controller, so that the air conditioner controller adjusts the roller blind to a position blocking the 1/2 communication port 102 by driving the motor, and the air conditioner controller controls the power of the bypass fan 310 to be reduced, thereby reducing the amount of air supplied to the cabinet 100 by the bypass housing 300.

As another example, when the amount of air supplied to the cabinet 100 by the bypass housing 300 is too small, the air speed detector sends an air speed signal to the air conditioning controller, the air conditioning controller adjusts the roller blind to completely avoid the position of the communication port 102 by driving the motor, and the air conditioning controller controls the power of the bypass fan 310 to be increased, thereby increasing the amount of air supplied to the cabinet 100 by the bypass housing 300.

Optionally, the curtain side of the roller blind between the two roller shafts abuts against the right side plate 101 of the cabinet 100. The curtain surface is attached to the right side plate 101, so that the communication tightness between the casing 100 and the bypass casing 300 can be improved, and particularly, under the condition that the communication opening 102 is completely shielded by a rolled-up and unrolled curtain, the air in the casing 100 is favorably prevented from entering the bypass casing 300 from the communication opening 102.

Optionally, the curtain face of the roller blind is a rubber curtain face. With the rubber curtain surface, when the rubber curtain surface is abutted against the inner wall of the casing 100, the sealing property of the communication between the casing 100 and the bypass casing 300 can be further improved.

The embodiment of the disclosure also provides an air conditioner, which comprises the indoor unit described in any one of the embodiments.
