In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the air guide door structure of the prior art air conditioner, a main board is fixedly connected with an auxiliary board, and when the air guide door structure is in an initial position state, the main board seals an air outlet to prevent dust from entering the air conditioner in a standby state; when the air guide door is in use, the upper edge of the air outlet has a limiting effect on the upper edge of the main board, so that the auxiliary board cannot rotate upwards and can only rotate downwards to open the air guide door, and the adjustment of the upper air guide angle and the lower air guide angle and the air supply distance of the main board are limited.
According to the air guide door structure provided by the embodiment of the invention, the main board 200 is arranged to be in sliding fit with the auxiliary board 300 and the frame body 100 at the same time, and the two sliding tracks are fitted to enable the main board 200 to rotate upwards along with the auxiliary board 300 and downwards along with the auxiliary board 300, and meanwhile, the main board 200 slides and extends outwards on the auxiliary board 300 in the rotating process along with the auxiliary board 300, so that the air supply distance is increased, and the large-angle and long-distance air supply of the main board 200 is realized. The specific structure and the movement principle of the air guide door structure in the embodiment of the present invention are analyzed in detail as follows, and the air guide door structure is located at the air outlet of the frame body 100 of the wall-mounted air conditioner as an example.
An embodiment of the present invention provides a wind guiding door structure, as shown in fig. 1a, 1b, and 1c, the wind guiding door structure is disposed at a position of an air outlet 102 of an air conditioner frame 100, and includes a main board 200 and a sub board 300; the sub-plate 300 is rotatably connected with the frame body 100, and the sub-plate 300 can rotate relative to the frame body 100 under the driving action of the driving device; the left and right sides of the main board 200 are slidably connected to the frame 100 and can slide on the frame 100 along a first predetermined track, and the main board 200 is slidably connected to the sub-board 300 and can slide on the sub-board 300 along a second predetermined track. When the main board 200 opens the air outlet 102, the main board rotates with the sub board 300 and slides outwards on the sub board 300 along the second preset track under the limiting action of the first preset track.
Fig. 2a shows a position of the sub-board 300 during the downward rotation from the initial position of fig. 1a, and fig. 3a shows an extreme position of the rotation direction, as can be seen from a comparison analysis in the figure, during the downward rotation of the sub-board 300, the main board 200 not only rotates along with the sub-board 300 to achieve downward adjustment of the air outlet angle, but also the main board 200 slides outward on the sub-board 300, that is, the main board 200 extends outward on the sub-board 300, and the air supply distance is increased.
Fig. 2a 'shows a position of the sub-board 300 during upward rotation from the initial position of fig. 1a, and fig. 3a' shows an extreme position of the rotation direction, and it can be seen from a comparison analysis in the figure that, during the upward rotation of the sub-board 300, the main board not only rotates with the sub-board 300 to achieve upward adjustment of the air outlet angle, but also the main board 200 slides outward on the sub-board 300, i.e., the main board 200 extends outward on the sub-board 300 to increase the air supply distance.
That is, it is assumed that the main board 200 closes the air outlet 102 in an initial state. In the process that the main board 200 swings upwards to open the air outlet 102, the auxiliary board 300 rotates upwards, the main board 200 rotates along with the auxiliary board 300, and the main board 200 slides relative to the frame body 100 and the auxiliary board 300 simultaneously, namely, the movement track of the main board 200 relative to the frame body 100 is a first preset track, and slides outwards on the auxiliary board 300 along a second preset track under the limiting action of the first preset track, so that the interference limitation between the upper edge of the main board 200 and the upper edge of the air outlet 102 of the frame body 100 is removed, the upward rotation of the auxiliary board 300 can be realized until the limit position state of the rotation direction is reached, and at the moment, the main board 200 reaches the maximum swing angle upwards; when the main board 200 swings downward to open the air outlet 102, the main board 200 rotates along with the sub board 300, and the main board 200 slides relative to the frame body 100 and the sub board 300 simultaneously, that is, the main board 200 slides outward on the sub board 300 along the second preset track under the limiting action of the first preset track, so that the interference limitation between the lower edge of the main board 200 and the lower edge of the air outlet 102 of the frame body 100 is removed, the downward rotation of the sub board 300 can be realized until the limit position state of the rotation direction is reached, and at this time, the main board 200 reaches the maximum swing angle downward. Since the main plate 200 slides outward on the sub-plate 300 in the process of opening the outlet 102, the air blowing distance is increased. Thereby realizing large-angle and long-distance air supply.
In short, during the rotation of the sub-board 300, the main board 200 is simultaneously limited by the first preset track and the second preset track, and the first preset track and the second preset track are fitted to form the movement track of the main board 200. The movement locus of the main board 200 can not only rotate upwards and downwards along with the auxiliary board 300 to realize swing at different angles, but also slide outwards on the auxiliary board 300 to realize remote air supply.

So set up, can guarantee that the movement track of mainboard 200 is only, and then can guarantee that the movement track of mainboard 200 is even, smooth, stable.
In this embodiment, in the process of rotating the sub plate 300, the only way that the position of the sliding shaft 201 in the first guide groove 101 is that the rotating angle of the sub plate 300 is in one-to-one correspondence with the sliding position of the sliding shaft 201 in the first guide groove 101.
Specifically, as shown in fig. 7a, 7b, 8a, and 8b, the first guide groove 101 is an arc-shaped groove, that is, the first preset track is an arc-shaped movement track along the arc-shaped groove, and the arc-shaped movement track can ensure that the main board 200 moves smoothly and stably.
The sliding connection between the main board 200 and the frame 100 is realized by the sliding fit between the sliding shaft 201 and the first guide groove 100, and the structure is simple, the manufacturing cost is low, and the disassembly is easy. In addition to this sliding connection, other sliding connection methods may be employed, for example, the first guide groove 101 is provided in the main board 200, and the slide shaft 201 is provided in the housing 100 (not shown); alternatively, a guide block and a guide rail are arranged between the main board 200 and the frame body 100, and the guide block can move along a first preset track under the guiding action of the guide rail (not shown in the figure); both of these sliding connections are also within the scope of the claimed invention.
