[0036] In order to make the above objectives, features and advantages of the present application more obvious and understandable, the present application is further described in detail below with reference to FIGS. 1-4.

[0037] Embodiments of the present application provide an air conditioner. With reference to FIG. 1, an air conditioner 100 includes a housing 110 and an outer air guide plate 130, wherein the housing 110 is provided with an air outlet 111, the outer air guide plate 130 is rotatably provided on an outer wall of the housing 110, so as to guide output air of the air outlet 111, and the outer air guide plate 130 is provided at a position corresponding to a position of the air outlet 111. One side of the outer air guide plate 130 is provided with a rotating shaft 131, wherein the rotating shaft 131 is provided outside the air outlet 111 and is located above the air outlet 111, and the outer air guide plate 130 is rotatably provided on the outer wall of the housing 110 via the rotating shaft 131. In the above, a length of the outer air guide plate 130 is greater than that of the air outlet 111 and / or a width of the outer air guide plate 130 is greater than that of the air outlet 111.

[0038] The outer air guide plate 130 is rotatably provided on the outer wall of the housing 110, a rotation process and a rotation angle thereof are visible, and a user can quickly determine whether an air guide angle of the outer air guide plate 130 is adjusted in place. Moreover, as the outer air guide plate 130 is provided outside the air outlet 111, a size thereof is not restricted by a size of the air outlet 111, and the outer air guide plate can be adjusted to have a larger size, so as to obtain a better air guiding effect. Since the length and / or width of the outer air guide plate 130 are greater than the length and / or width of the air outlet 111, the outer air guide plate 130 may completely shield the air outlet 111, and airflow of the air outlet 111 may be completely guided by the outer air guide plate 130, thus the outer air guide plate 130 has a superior flow guiding effect, and when the air conditioner 100 is not used, dust entering the air outlet 111 may be reduced, and service life of the air conditioner 100 is prolonged.

[0039] A rotating portion 113 is provided on the outer wall of the housing 110 at a position corresponding to above the air outlet 111, and the rotating shaft 131 is rotatably fitted with the rotating portion 113. In the present embodiment, in order to improve rotation tightness of the outer air guide plate 130 and prevent generation of condensation on the outer wall of the housing 110. The rotating portion 113 is provided with a groove, and the rotating shaft 131 provided on the outer air guide plate 130 is embedded in the groove and is rotatably fitted with the groove.

[0040] By providing the rotating shaft 131 and the groove, the outer air guide plate 130, when rotating, is always tightly arranged in the groove, and the output air of the air outlet 111 is guided along the outer air guide plate 130, and is not easy to contact the outer wall of the housing 110 from a rotation position.

[0041] In order to further improve a utilization rate of the outer air guide plate 130, in the present embodiment, the groove is connected to an upper edge of the air outlet 111 and is parallel to an extension direction of the upper edge of the air outlet 111. The groove being connected to and extending in parallel with the upper edge of the air outlet 111 ensures that the outer air guide plate 130, after mounted to the groove, has air guiding effect in a wider area, which further improves an air-guiding utilization rate of the outer air guide plate 130.

[0042] In order to ensure that the outer air guide plate 130, after mounted to the groove, can fully cover the housing 110 in a horizontal direction, which avoids an uncovered region where a gap is generated on a surface of the housing 110 to cause generation of condensation. In the present embodiment, one end of the groove is formed on an end wall of one end of the housing 110 in the horizontal direction, and the other end of the groove extends to an end wall of the other end of the housing 110 in the horizontal direction. That is, the groove penetrates through two ends of the housing 110 in the horizontal direction.

[0043] After the outer air guide plate 130 is mounted to the groove, in order to implement smooth rotation, and further ensure tight fit between the outer air guide plate 130 and the housing 110 so as to prevent generation of a too big gap, in the present embodiment, a cross section of the groove is in a semi-circular arc shape.

[0044] The rotating shaft 131 is embedded in the groove, so as to realize rotatable fit between the outer air guide plate 130 and the housing 110. As the groove is recessed in the outer wall of the housing 110, outward protruding of the joint of the outer air guide plate 130 and the housing 110 is avoided, thus improving an overall aesthetic degree of the air conditioner 100.

[0045] In order to ensure the anti-condensation effect, lengths of the rotating shaft 131 and the outer air guide plate 130 are both corresponding to the length of the groove, and are both greater than the length of the air outlet 111. That is, in cases where the rotating shaft 131 is embedded in the groove, two ends of the rotating shaft 131 are coplanar with end walls of the two ends of the groove respectively, and two ends of the outer air guide plate 130 in the length direction are coplanar with the end walls of the two ends of the groove, respectively.

[0046] Referring to FIG. 1, the air conditioner 100 further includes an air guide mechanism, wherein the air guide mechanism is provided on the housing 110, and the air guide mechanism and the outer air guide plate 130 jointly form an air guide channel capable of changing a wind direction of the output air, so as to guide the output air of the air outlet 111. In the prior art, a wind direction is fixed in a direction of the air outlet 111, and the output air is only guided by the outer air guide plate 130, without changing the wind direction. By providing the air guide mechanism, the air guide mechanism cooperates with the outer air guide plate 130, so that the wind direction may be changed to a direction showing the best effect, and the air conditioner 100 may achieve the best effect when used, and comply with use requirements of users.

[0047] The air guide mechanism includes an inner air guide plate 150, wherein the inner air guide plate 150 is rotatably provided on the housing 110, and the outer air guide plate 130 and the inner air guide plate 150 are used to jointly form the air guide channel, so as to guide the output air of the air outlet 111. The outer air guide plate 130 and the inner air guide plate 150 cooperate with each other. The inner air guide plate 150 may flexibly rotate along with the outer air guide plate 130, so as to achieve the purpose of changing the wind direction.

[0048] The inner air guide plate 150 is rotatably provided on a side wall inside the air outlet 111 and away from the outer air guide plate 130. One side of the inner air guide plate 150 is provided with a rotating crank arm 151, wherein one end of the rotating crank arm 151 away from the inner air guide plate 150 is rotatably connected to the side wall inside the air outlet 111 and away from the outer air guide plate 130. The rotating crank arm 151 increases a rotation angle range of the inner air guide plate 150, so that the inner air guide plate 150 can completely rotate out of the air outlet 111, so as to obtain a larger air guide angle.

[0049] Referring to FIG. 2, a maximum air shielding area of the outer air guide plate 130 is greater than a maximum air shielding area of the inner air guide plate 150. In a power-off state of the air conditioner 100, the inner air guide plate 150 is received in the air outlet 111, and the outer air guide plate 130 shields the air outlet 111, so that the outer air guide plate 130 and the inner air guide plate 150 are less likely to interfere with each other, and meanwhile have a certain protection effect on the inner air guide plate 150 in the power-off state.

[0050] With reference to FIG. 2 and FIG. 3, the outer air guide plate 130 and the inner air guide plate 150 are both provided in an arc shape. When the air conditioner 100 operates in a heating mode from the power-off state, the inner air guide plate 150 rotates to the outside of the air outlet 111, the outer air guide plate 130 rotates at a first angle, and the outer air guide plate 130 and the inner air guide plate 150 form an inclined downward air guide channel, so that the airflow blown out from the air outlet 111 obliquely flows downwards along a side of the outer air guide plate 130 close to the inner air guide plate 150, and in this case, a concave arc surface of the outer air guide plate 130 is opposite to a concave arc surface of the inner air guide plate 150. The outer air guide plate 130 and the inner air guide plate 150 are both provided in an arc shape. The concave surface of the outer air guide plate 130 faces one side of the outer air guide plate 130 close to the air outlet 111, and the concave surface of the inner air guide plate 150 faces one side of the inner air guide plate 150 close to the air outlet 111.

[0051] In the prior art, the air guide plate is provided in the air outlet 111, an air guiding size thereof is restricted by the size of the air outlet 111, and the flow guiding effect on the output air is limited. During the operation of the air conditioner 100 in the heating mode, hot air will immediately float upwards after being blown out from the air outlet 111, which results in a large amount of hot air being gathered in an upper space of a room, causing the user to feel that the head is hot and feet are cold, such that the heating effect on the whole room is poor. In the present embodiment, the outer air guide plate 130 is provided outside the housing 110, the size thereof is not restricted by the size of the air outlet 111, and all the output air of the air outlet may be guided, thus the pressing down effect on the hot air is better, and the heating effect on the whole room is better. Moreover, the outer air guide plate 130 is an arc-shaped plate, with end hanging down, and has a better pressing down effect on the hot air.

[0052] With reference to FIG. 2 to FIG. 4, when the air conditioner 100 operates in a cooling mode from the power-off state, the inner air guide plate 150 rotates to the outside of the air outlet 111, the outer air guide plate 130 rotates at a second angle, in this case, the concave arc surface of the outer air guide plate 130 is opposite to the concave arc surface of the inner air guide plate 150, and the outer air guide plate 130 and the inner air guide plate 150 form an approximately horizontal air guide channel, where the second angle is greater than the first angle.

[0053] As the hot air and the cold air have different airflow distributions, the cold air needs to be transported farther in order to achieve a better cooling effect. By providing the outer air guide plate 130 outside the housing 110, the size of the outer air guide plate is not restricted by the size of the air outlet 111, and then the outer air guide plate may be provided to be longer in size, so as to ensure that the cold air can be blown farther, and improve the cooling effect. In the cooling mode, as the inner air guide plate 150 is an arc-shaped plate, with ends upturned, it is more conducive to long-distance transport of the cold air.

[0054] In conclusion, in practical application of the air conditioner 100 provided in the present embodiment, as the outer air guide plate 130 is provided on the outer wall of the housing 110, the rotation process and the rotation angle thereof are visible, and the user can quickly determine whether the outer air guide plate 130 is adjusted in place by observing with naked eyes when adjusting the air guide angle, so that the user obtains a good use feeling. Moreover by providing the outer air guide plate 130 outside the air outlet 111, the outer air guide plate may be adjusted to a larger size, so as to obtain a better air guiding effect and prevent generation of condensation.

[0055] The implementation principle of the embodiments of the present application is as follows: when the air conditioner 100 needs to be used, the air conditioner 100 is turned on, in this case, the outer air guide plate 130 rotates to open, and after the outer air guide plate 130 is opened, the inner air guide plate 150 rotates to open, so that the air guide channel between the outer air guide plate 130 and the inner air guide plate 150 is opened. During the operation of the heating mode, the outer air guide plate 130 and the inner air guide plate 150 rotate to form a hot air down-pressing channel, so that the airflow blown out from the air outlet 111 flows obliquely downwards, thereby rendering a better heating effect. During the operation of the cooling mode, the outer air guide plate 130 and the inner air guide plate 150 rotate to form a cold air up-rising channel, so that the airflow blown out from the air outlet may transport cold air over a long distance, thereby rendering a better cooling effect. After the use is completed, the air conditioner 100 is turned off, and in this case, first the inner air guide plate 150 rotates back into the housing 110, and then the outer air guide plate 130 rotates to cover at the air outlet 111.
