[0042] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0043] With the development of economy and society, people are pursuing higher and higher quality of life. Various air conditioning systems in our daily life are developing towards intelligence, comfort and fashionable appearance. At present, the duct air conditioners commonly used in the field have the advantages of being hidden, occupying small space and low transportation cost, but they also have the disadvantages of single air outlet, which leads to small heat exchange area and poor heat exchange effect, thus making the user experience poor.

[0044] Based on the above questions, please refer to Figures 1 to 6 The present invention provides an air conditioner 10, which adopts a rotatable active air duct 240 that can change the air outlet direction, so as to increase the air outlet range by changing the air outlet direction, solve the problem of the single air outlet 122 of the original air conditioner 10, and effectively improve the user experience.

[0045] In detail, the air conditioner 10 includes a housing 100, a wind wheel mechanism 200, a first driving mechanism 300, a second driving mechanism 400 and a heat exchange mechanism 500. The wind wheel mechanism 200, the first driving mechanism 300, the second driving mechanism 400 and the heat exchange mechanism 500 are all disposed on the housing 100, and the first driving mechanism 300 and the second driving mechanism 400 are both connected to the wind wheel mechanism 200 to provide power to the wind wheel mechanism 200.

[0046] In detail, the outer shell 100 is provided with an air inlet 121, an air outlet 122 and a vent 111; the wind wheel mechanism 200 includes a wind wheel 210 and a volute 220, the wind wheel 210 is arranged in the outer shell 100, and the volute 220 can be movably arranged on the wind wheel 210 so that one end of the air duct 240 formed by the volute 220 is connected to the vent 111, and the other end corresponds to the air inlet 121; or one end of the air duct 240 formed by the volute 220 is connected to the air outlet 122, and the other end corresponds to the vent 111.

[0047] In this embodiment, an air outlet 122 and a vent 111 are simultaneously provided on the outer casing 100, and a rotatable volute 220 is provided, so that the air duct 240 formed by the volute 220 is connected to the air outlet 122 or the vent 111, so that air is discharged through the air outlet 122 or the vent 111. This increases the air outlet direction of the air conditioner 10 and increases the air outlet range of the air conditioner 10, thereby effectively and quickly meeting the user's heat exchange needs and significantly improving the user experience.

[0048] It should be noted that the wind wheel mechanism 200 further includes a volute tongue 230 , and the volute 220 and the volute tongue 230 are snap-connected to form an air duct 240 together.

[0049] In this embodiment, the two side walls of the volute 220 in the length direction are provided with a clamping hole 221, and the two ends of the volute tongue 230 are protruding with a buckle 231. By inserting the buckle 231 into the clamping hole 221, the volute 220 and the volute tongue 230 are firmly connected.

[0050] Specifically, the housing 100 includes a front frame 110 , a middle frame 120 and a back plate 130 which are connected in sequence. The wind wheel mechanism 200 , the first driving mechanism 300 and the second driving mechanism 400 are all arranged in the middle frame 120 , and the heat exchange mechanism 500 is arranged in the front frame 110 .

[0051] In this embodiment, the air inlet 121 is arranged on the top wall of the middle frame 120, the front frame 110 is arranged on one side of the middle frame 120, the vent 111 is arranged on the front frame 110, and the air outlet 122 is arranged on the top wall of the middle frame 120, so as to realize two air outlet modes of the air conditioner 10, namely, the horizontal air outlet mode and the vertical downward air outlet mode.

[0052] like Figure 5 As shown, in the horizontal air outlet mode, the air duct 240 formed by the volute 220 is connected to the vent 111, and the wind wheel 210 is driven to rotate by the first driving mechanism 300, so that under the action of the wind wheel 210, the wind enters the air duct 240 where the volute 220 is located from the air inlet 121, and is blown out horizontally from the vent 111 along the volute 220.

[0053] Switch to vertical downward air outlet mode, such as Figure 6 As shown, the second driving mechanism 400 needs to drive the volute 220 to rotate so that the air duct 240 formed by the volute 220 rotates with the volute 220 until it is connected with the air outlet 122. In this case, the vent 111 is the air inlet 121, and the ground wind is blown out vertically from the air outlet 122 along the volute 220.

[0054] Of course, in other embodiments, the shape of the housing 100 may also be cylindrical, that is, the direction of the air outlet 122 is set at an angle to the direction of the vent 111. As long as the air outlet direction can be changed by rotating the volute 220, no specific limitation is made here.

[0055] In this embodiment, the angle between the direction of the air outlet 122 and the direction of the ventilation port 111 is 90°. Correspondingly, the rotatable angle of the volute 220 is set to correspond to the angle of 90°, which can prevent the rotation angle of the volute 220 from being too large or too small.

[0056] Furthermore, the heat exchange mechanism 500 includes a heat exchanger 510 , a side plate 520 and a water receiving box 530 .

[0057] In this embodiment, the heat exchanger 510 is disposed at the vent 111 to ensure that the wind exchanges heat with the heat exchanger 510 when flowing through the vent 111, thereby achieving the purpose of blowing hot air or cold air.

[0058] The heat exchanger 510 may be an evaporator, which is installed in the front frame 110 through the side plate 520. The water receiving box 530 is arranged at the bottom of the evaporator to receive and discharge condensed water generated during the operation of the evaporator.

[0059] Specifically, the vent 111 is disposed on the front frame 110 , and the air inlet 121 and the air outlet 122 are disposed on the top wall and the bottom wall of the middle frame 120 , respectively.

[0060] Furthermore, the outer shell 100 is provided with a first partition 140 and a second partition 150 at the vent 111. Specifically, the middle frame 120 is provided with an opening connected to the outer frame, and the first partition 140 and the second partition 150 are provided at the opening; therefore, when the air duct 240 is connected with the vent 111, the volute tongue 230 is connected with the first partition 140, and the volute 220 is connected with the second partition 150 to jointly form an air outlet channel, so that the wind entering from the air inlet 121 can all flow out through the vent 111 to ensure the air output.

[0061] Furthermore, a third partition 160 and a fourth partition 170 are provided at the outer shell 100 and the air outlet 122. Therefore, when the air duct 240 is connected to the air outlet 122, the volute tongue 230 is connected to the third partition 160, and the volute 220 is connected to the fourth partition 170, so that the wind entering from the vent 111 can all flow out through the air outlet 122 to ensure the air output.

[0062] Furthermore, the first driving mechanism 300 includes a main motor 310, a motor base 320 and a motor pressure plate 330. The main motor 310 is installed between the motor base 320 and the motor pressure plate 330. The main motor 310 is transmission-connected to the wind wheel 210 to drive the wind wheel 210 to rotate.

[0063] Furthermore, the second driving mechanism 400 includes a motor 410, a base 420, a transmission member 430 and a sleeve 440. The base 420 is arranged in the outer shell 100, and the motor 410 is arranged on the base 420. The motor 410 is connected to the transmission member 430 through the sleeve 440. The transmission member 430 is connected to the volute 220 for driving the volute 220 to rotate under the drive of the motor 410.

[0064] In this embodiment, the transmission member 430 is driven to rotate by the motor 410 , and the transmission member 430 drives the volute 220 to rotate, so that the air duct 240 formed by the volute 220 is connected to the vent 111 or the air outlet 122 .

[0065] Optionally, the motor 410 may be, but is not limited to, a stepper motor 410 .

[0066] In detail, the transmission member 430 is provided with a clamping portion 431 , and the volute 220 is provided with a clamping slot 222 , and the clamping portion 431 is clamped with the clamping slot 222 .

[0067] In this embodiment, the holding portion 431 is engaged with the slot 222 of the volute 220 to stably drive the volute 220 to rotate.

[0068] Furthermore, the base 420 is provided with a guide hole 421 , and the guide hole 421 is used for the holding portion 431 to pass through and limit the movement of the holding portion 431 .

[0069] In this embodiment, the guide hole 421 is arc-shaped, and the clamping portion 431 can be movably inserted into the guide hole 421 and can move along the arc-shaped trajectory of the guide hole 421 to drive the volute 220 to accurately rotate to the connection point with the vent 111 or the outlet 122.

[0070] In summary, an embodiment of the present invention provides an air conditioner 10, by simultaneously arranging an air outlet 122 and a vent 111 on the outer casing 100, and arranging a rotatable volute 220, so that the air duct 240 formed by the volute 220 is connected to the air outlet 122 or the vent 111, so that air is discharged through the air outlet 122 or the vent 111, thereby increasing the air outlet direction of the air conditioner 10 and increasing the air outlet range of the air conditioner 10, thereby effectively and quickly meeting the user's heat exchange needs and significantly improving the user experience.
