The second plate 12 is located on the upper side of the first plate 11, and the air flow passes through the air deflector from the rear to the front along the upper surface of the second plate 12 on the upper side of the second plate 12. When the air flow temperature is lower than the first set value, the second plate 12 is in the first state, at this time, the lower surface of the second plate 12 is attached to the first surface 11a, and the upper surface of the second plate 12 is recessed downward toward the direction approaching the first surface 11a, that is, the upper surface of the second plate 12 may be formed as a concave surface; when the air flow temperature is higher than the second set value, the second plate 12 is in the second state, at which the lower surface of the second plate 12 is separated from the first surface 11a, and the second plate 12 protrudes upward toward a direction away from the first surface 11a, that is, the upper surface of the second plate 12 is formed to be convex.

Wherein the first setting is smaller than the second setting, for example, the first setting may be 35 ° and the second setting may be 40 °. It is understood that the first setting value and the second setting value may be set according to parameters such as the outlet air temperature in different operation modes of the air conditioner 200.
According to the air deflector provided by the embodiment of the invention, the second plate body 12 is arranged, so that the second plate body 12 can be deformed to the first form or the second form according to the air flow temperature, and the flow of the air flow can be better guided. When the air guide plate is applied to the air conditioner 200, the user's comfort in use can be improved.
In an alternative embodiment of the invention, the first plate body 11 is formed as an arc-shaped plate protruding in a direction toward the second surface 11 b. For example, as shown in fig. 4, the second surface 11b is located at the lower end of the first plate 11, and the first plate 11 is formed as a downwardly convex arc plate, so that when the first surface 11a is deformed to the first configuration, the upper surface of the second plate 12 is conveniently formed as a concave surface. Meanwhile, when the air deflector is applied to the air conditioner 200, the air deflector is rotatably disposed at the air outlet 101a of the air conditioner 200, and when the air conditioner 200 is in a closed state (as shown in fig. 1), the air deflector rotates to shield the air outlet 101a, and the first plate 11 protrudes outwards to match with the surface of the air conditioner 200, thereby improving the aesthetic property of the whole air conditioner 200. Here, the direction "outside" refers to a direction away from the center of the air conditioner 200.
Further, on the cross section of the air deflector, the connection line of the two free ends of the second plate body 12 is a reference connection line 10a, the length of the reference connection line 10a is L, the surface of the second plate body 12, which is attached to the first plate body 11, is an attaching surface 12a, and when the second plate body 12 protrudes toward the direction approaching the first surface 11a, the longest protruding distance between the attaching surface 12a and the reference connection line 10a is B 1 Wherein 1/10.ltoreq.B 1 L is less than or equal to 1/4; when the second plate body 12 protrudes in a direction away from the first surface 11a, the longest protruding distance between the surface of the second plate body 12 opposite to the bonding surface 12a and the reference line 10a is B 2 Wherein 1/10.ltoreq.B 2 /L≤1/4。
Specifically, the first plate 11 and the second plate 12 may be substantially equal-thickness members, the bonding surface 12a is located at the lower end of the second plate 12, when the second plate 12 is in the first configuration, as shown in fig. 3 and 4, the second plate 12 protrudes downward toward the direction close to the first surface 11a to bond the bonding surface 12a to the first surface 11a, and at this time, in the cross section of the air deflector, the longest protruding distance between the bonding surface 12a and the reference line 10a is B 1 ，B 1 Satisfy 1/10.ltoreq.B 1 L is less than or equal to 1/4, thereby avoiding B 1 Too small/L results in a gentle upper surface of the second plate 12, so that the air flow cannot be guided to flow upwards after passing through the second plate 12At the same time avoid B 1 Too large/L results in the upper surface of the second plate body 12 being too steep, which affects the air supply distance and the air volume.
When the second plate body 12 is in the second configuration, as shown in fig. 6, the second plate body 12 protrudes upward in a direction away from the first surface 11a to separate the bonding surface 12a and the first surface 11a from each other, and at this time, in the cross section of the air deflector, the longest protruding distance between the upper surface of the second plate body 12 and the reference line 10a is B 2 ，B 2 Satisfy 1/10.ltoreq.B 2 L is less than or equal to 1/4, thereby avoiding B 2 Too small/L, which results in a gentle upper surface of the second plate 12, so that the air flow cannot be guided to flow downwards after passing through the second plate 12, while avoiding B 2 Too large/L results in the upper surface of the second plate body 12 being too steep, which affects the air supply distance and the air volume.
Thus, by setting B 1 Satisfy 1/10.ltoreq.B 1 /L≤1/4、B 2 Satisfy 1/10.ltoreq.B 2 And L is less than or equal to 1/4, so that the air deflector has good guiding effect on air flow when the second plate body 12 is in the first form or the second form. Further, B 1 Can be combined with B 2 The first and second shapes of the second plate 12 are equal, that is, symmetrical about the reference line 10 a.
Optionally, the second plate 12 is a piece of shape memory material. Therefore, other devices are not required to be arranged, the second plate body 12 can sense the temperature of the air flow flowing through the second plate body 12, and accordingly the air flow can be automatically adjusted to the first form or the second form according to the air flow temperature, the user is greatly facilitated, and meanwhile, the structure of the air deflector is simplified.
Wherein the shape memory material is a thermal shape memory material. Specifically, when the air deflector is applied to the air conditioner 200, the air conditioner 200 is turned off, the air temperature around the second plate 12 is lower than the first set value, and the second plate 12 is automatically adjusted to the first shape; when the air conditioner 200 is refrigerating, the temperature of the air flow flowing through the second plate 12 is lower than the first set value, and the second plate 12 is automatically deformed to the first form; when the air conditioner 200 heats, the temperature of the air flow flowing through the second plate 12 is higher than the second set value, and the second plate 12 is automatically deformed to the second shape.

It will be appreciated that the two ends of the second plate body 12 may also be fixedly connected or otherwise detachably connected to the two ends of the first plate body 11, for example by a bolt structure.
In a further embodiment of the present invention, the two ends of the first plate 11 are respectively formed with a clamping groove 111, and the two ends of the second plate 12 are respectively provided with a clamping protrusion 121 matched with the clamping groove 111. For example, in the examples of fig. 3, 4, 6 and 7, the catching grooves 111 are formed at the front and rear ends of the first plate body 11, respectively, the catching grooves 111 extend in the left-right direction and penetrate the left and right ends of the first plate body 11, and the catching grooves 111 at both ends of the first plate body 11 may be formed by downwardly recessing a portion of the first surface 11a in a direction away from each other. The clamping protrusions 121 are respectively disposed at the front end and the rear end of the second plate body 12, the clamping protrusions 121 extend to the left end and the right end of the second plate body 12 along the left-right direction, and the clamping protrusions 121 at the two ends of the second plate body 12 can be formed by downward protruding a part of the bonding surface 12a towards a direction away from each other. The clamping protrusions 121 are correspondingly assembled into the clamping grooves 111, so that the first plate 11 and the second plate 12 can be assembled, the structure is simple, the assembly is convenient, the efficiency is high, and meanwhile, the connection strength between the first plate 11 and the second plate 12 is ensured.
