[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0054] The present solution provides an air guide device and an air conditioner, wherein the air guide device 100 comprises an air guide member 110, a transmission shaft, a seal and a force transmission structure 160, wherein the transmission shaft is connected to the air guide member 110, the seal is movably installed on the transmission shaft, the force transmission structure 160 is arranged between the air guide member 110 and the seal, the force transmission structure 160 is used to convert the rotational motion of the transmission shaft into the linear motion of the seal, when the air guide member 110 is closed, the rotation of the transmission shaft drives the air guide member 110 to rotate, and through the force transmission structure 160, the seal moves along the axial direction of the transmission shaft, that is, the seal moves toward the end of the air guide member 110 and fits the end of the air guide member 110 connected, thereby covering the gap between the wind shield and the air outlet, when the air guide member 110 is opened, the rotation of the transmission shaft drives the air guide member 110 to rotate, and the seal can move away from the air guide member 110 under the rotation of the transmission shaft, thereby facilitating the rotation and opening of the air guide member 110.

[0055] Combination Figure 1-4 As shown, the air guide device 100 includes an air guide member 110, a transmission shaft, a seal and a force transmission structure 160. The air guide member 110 is a long plate-like structure. The air guide member 110 includes a first end and a second end located in the length direction. Rotating ear seats 111 are respectively arranged near the first end and the second end of the air guide member 110.

[0056] In this solution, the first end and / or the second end are respectively provided with the transmission shaft, and the transmission shaft at the first end and / or the transmission shaft at the second end are respectively installed with the sealing member.

[0057] In the present embodiment, two seals are provided on the air guide member 110 for introduction. For the sake of clarity, the transmission shaft provided at the first end is defined as the first transmission shaft 120, the transmission shaft provided at the second end is defined as the second transmission shaft 130, the seal installed on the first transmission shaft 120 is defined as the first seal 140, and the seal installed on the second transmission shaft 130 is defined as the second seal 150. The first transmission shaft 120 is movably connected to the first seal 140 through a force transmission structure 160, and the second transmission shaft 130 is movably connected to the second seal 150 through the force transmission structure 160. The first seal 140 and the second seal 150 are respectively provided with connecting ear seats 141, and the first transmission shaft 120 and the second transmission shaft 130 respectively extend out of the air guide member 110.

[0058] Combination Figure 2-3 As shown, in this solution, the force transmission structure 160 includes an external thread 161 and an internal thread 162, that is, the first seal 140 and the first transmission shaft 120 and the second seal 150 and the second transmission shaft 130 are respectively connected by threads.

[0059] The first transmission shaft 120 and the second transmission shaft 130 are respectively provided with external threads 161, and the spiral directions of the external threads 161 on the first transmission shaft 120 are opposite to those of the external threads 161 on the second transmission shaft 130. In this solution, the first sealing member 140 and the second sealing member 150 have the same structure, so only the first sealing member 140 is described in terms of structure. Figure 4 As shown, a connecting hole 142 is formed on the connecting ear seat 141 of the first sealing member 140, and the internal thread 162 includes a first thread protrusion 162'1 and a second thread protrusion 162'2 disposed in the connecting hole 142, and the first thread protrusion 162'1 and the second thread protrusion 162'2 are disposed oppositely on both sides of the connecting hole 142. According to the understanding of those skilled in the art, the first thread protrusion 162'1 and the second thread protrusion 162'2 are staggered to adapt to the spiral external thread 161.

[0060] When the air guide assembly is installed on the air conditioner, the movement of the first seal 140 and the second seal 150 is realized by limiting the rotation of the first seal 140 and the second seal 150. When the air guide 110 rotates and closes, the first seal 140 moves toward the end of the first end of the air guide 110, and the second seal 150 moves toward the end of the second end of the air guide 110, thereby blocking the gap between the two ends of the air guide plate and the air outlet. When the air guide 110 rotates and opens, that is, the air guide 110 rotates in the opposite direction relative to the closed state, the first seal 140 moves away from the first end of the air guide 110, and the second seal 150 moves away from the second section of the air guide 110, thereby facilitating the rotation and opening of the air guide 110. The first seal 140 and the second seal 150 respectively block the gaps at the two ends of the air guide 110, avoiding air leakage after the air guide 110 is closed, and eliminating the problem of black leakage in the gap. The aesthetics of the air conditioner can be improved.

From the flow direction of the air flow in the air outlet channel 700, the air flow first passes through the first air outlet 710 and then passes through the second air outlet 720. According to the understanding of those skilled in the art, according to the setting method of the air outlet channel 700, the second air outlet 720 can also be located above the first air outlet 710.

[0062] The air guide device 100 is installed at the first air outlet 710. When the air guide member 110 rotates to open the first air outlet 710, the air guide member 110 rotates toward the inside of the air outlet channel 700, and the air guide member 110 rotates to the side of the first air outlet 710 facing the second air outlet 720 to block the air flow to the second air outlet 720. In this embodiment, the air guide member 110 is a long plate-like structure, and the surface profile of the air guide member 110 is similar to the cross-sectional profile of the air outlet channel 700 in size and shape, so that the air guide member 110 blocks the air outlet channel 700 as much as possible, ensuring the air outlet efficiency of the first air outlet 710.

[0064] Combination Figure 4 and Fig. 9 As shown, although the second seal 150 is installed on the side of the side plate 600 facing away from the air guide member 110, the second seal 150 is connected to the second transmission shaft 130 via the connecting ear seat 141, and a portion of the second seal 150 extends from the end of the side plate 600 toward the air guide member 110, thereby achieving a close connection between the second seal 150 and the air guide member 110, and the side plate 600 can also limit the movement of the second seal 150 to prevent the second seal 150 from excessively squeezing the air guide member 110.

[0065] In this solution, one or two driving members 800 may be provided. If two driving members 800 are provided, two side panels 600 in the length direction of the first air outlet 710 are respectively provided with motor seats 610 to facilitate the installation of the driving member 800 and ensure the stability of the connection of the driving member 800.
