Referring to fig. 1 to 2 and 7 to 8, the air guide member 100 may include a housing 110, an upper communication duct 130 fixed in the housing 110, and an air outlet frame 120. Specifically, the bottom wall and the top wall of the casing 110 may be respectively provided with an air inlet opening 1111 and an air outlet opening 1112. The air inlet of the upper communication duct 130 may be configured to interface with the air inlet opening 1111 to receive the air flow outside the housing 110. The air outlet frame 120 may be configured to cover the air outlet of the upper communication air duct 130 in the air duct, and be controllably movable between an open position where the air outlet is exposed above the air outlet 1112 and a closed position completely inside the casing 110, so as to guide the air flow from the upper communication air duct 130 to the front side of the casing 110 when in the open position and lower the center of gravity of the air guiding member 100 when in the closed position.

In some preferred embodiments, the upper communication duct 130 may be disposed to extend from the bottom to the top and to the front, so as to reduce a gap between the air outlet frame 120 and the upper communication duct 130 when in the open position, and reduce the overall size of the air guide member 100. Fig. 5 is a schematic partial enlarged view of a region C in fig. 2, which shows the matching structure of the supporting portion 116 of the housing 110 and the corresponding air-out frame 120. Referring to fig. 2 and 5, further, the air-out frame 120 may include an air-out frame main body 121 provided with an air duct and a pivot portion 122 extending rearward from a rear side edge of the air inlet of the air-out frame main body 121. The rear end of the pivoting portion 122 may be formed with a pivoting hole 1221 configured to be engaged with a shaft hole of a pivoting shaft 141 fixed to the rear portion of the housing 110, so as to rotate the outlet frame 120 around the pivoting shaft 141. The pivot shaft 141 is preferably disposed at the rear side of the air duct of the air-out frame 120 to increase the rotation radius of the air duct of the air-out frame 120 around the pivot shaft 141, so as to reduce the gap between the air duct 120 and the upper communication air duct 130 when the air-out frame 120 is in the open position. The wind guiding member 100 may further include another pivot shaft 141, and the two pivot shafts 141 may be respectively fixed to two lateral sidewalls of the casing 110, so as to facilitate installation of the air-out frame 120.

Particularly, the inventor of the present application creatively designs the air outlet frame 120 to always emit the air outlet cover, the upper portion of which is communicated with the air duct 130, into the air duct thereof in the process of moving between the open position and the closed position, so that the air flow uninterruptedly flows through the upper air supply air duct and the air outlet frame 120, thereby solving the technical problems of low air flow rate, non-compact overall structure and high noise of the indoor unit of the cabinet air conditioner with the movable air outlet frame 120 in the prior art, and improving the air outlet effect of the air conditioner and the user experience.

Further, according to the present invention, the upper communicating air duct 130 is designed to extend from bottom to top and forward, so as to increase the rotation radius of the air outlet frame 120, and reduce the cross-sectional area of the air outlet frame 120 and the gap between the air outlet frame and the upper communicating air duct 130, thereby enabling the structure of the air guide member 100 to be more compact and the air flow to be smoother.

FIG. 4 is a schematic partial enlarged view of region B of FIG. 2, showing the elastomeric seal 170 and the stop member 180; fig. 18 is a schematic cross-sectional view of the elastomeric seal 170 of fig. 4. Referring to fig. 4 and 18, in some preferred embodiments, the peripheral portion of the outlet of the upper communication duct 130 may be provided with an elastic sealing member 170. The elastic sealing member 170 is configured to contact the air outlet frame 120 and generate a compressive deformation when the air outlet frame 120 moves to the open position, so as to prevent the air flow from flowing out through the gap between the upper communicating air duct 130 and the air outlet frame 120. A limiting member 180 may be disposed at a periphery of the air inlet of the air-out frame 120, and the limiting member 180 may be configured to contact the elastic sealing member 170 when the air-out frame 120 moves to the open position, so as to prevent the air flow from flowing out through a gap between the upper communication air duct 130 and the air-out frame 120 and prevent the air-out frame 120 from moving over.

Specifically, the limiting member 180 may include a limiting portion 181 extending inward from a circumferential edge of the air inlet of the air-out frame 120 and a fixing portion 182 extending outward from an outer end of the limiting portion 181. The fixing portion 182 may be configured to be fixedly connected to the pivot portion 122 and a plurality of limiting installation posts 123 extending outward from the front outer wall and the two lateral outer walls of the air-out frame body 121. The fixing portion 182 may have a positioning groove 183 formed on a surface thereof facing the air-out frame body 121, and the positioning groove 183 may be configured to be matched with a front end portion and two lateral end portions of the air-out frame body 121 on the air-intake side, so as to facilitate installation and positioning of the limiting member 180. The elastic sealing member 170 may include a trim portion 171 that is snap-fitted to a peripheral portion of the outlet port of the upper communication duct 130, and a sealing portion 172 that extends downward and outward from an outer peripheral wall or a bottom surface of the trim portion 171. The sealing portion 172 is configured to deform upward when the air-out frame 120 moves to the open position and closely attach to the limiting portion 181 of the limiting member 180. In some further preferred embodiments, the trim portion 171 may be formed with an annular trim groove 1711 for trim-fitting with a peripheral portion of the upper communication duct 130. The peripheral portion of the upper communicating air duct 130 may be composed of a parallel section 1331 extending in a direction parallel to the air outlet of the upper communicating air duct 130 and a perpendicular section 1332 extending from the outer end of the parallel section 1331 in a direction perpendicular to the air outlet, so as to facilitate the installation and positioning of the elastic sealing member 170 and effectively prevent the elastic sealing member 170 from falling off. The elastic sealing member 170 may further include a stopper 173 extending downward from the bottom surface of the trim portion 171 and disposed inside the sealing portion 172. The stopping portion 173 may be configured to limit the inner end of the limiting portion 181 to the outer side when the air-out frame 120 moves to the open position, so as to prevent the air flow from being exposed due to the gap between the sealing portion 172 and the limiting portion 181 caused by the deflection of the air-out frame 120 during the movement.

FIG. 11 is a schematic exploded view of the drive unit 150 of FIG. 8; fig. 12 is a schematic exploded view of the drive device 150 of fig. 8 from another angle; fig. 13 is a schematic exploded view cross-sectional view of the drive device 150 of fig. 8. Referring to fig. 11 to 13, in some preferred embodiments, the air guide member 100 may further include a driving device 150 for driving the air-out frame 120 to move between the open position and the closed position. The driving device 150 may include a guide 154, a base 151, a gear 153, and a driving motor 152. Wherein the base 151 may be configured to be fixedly connected with the air-out frame 120. The drive motor 152 may be configured to be fixedly coupled to the base 151 and an output shaft thereof may be configured to be drivingly coupled to the gear 153 to power rotation of the gear 153. The guide 154 may be configured to be fixedly coupled to the housing 110 and have an arc-shaped rack 1541 engaged with the gear 153 to define a movement path of the gear 153 and thus the movement path of the wind frame 120. The number of the driving devices 150 may be two, and the two driving devices are respectively disposed at two lateral sides of the air-out frame 120 to improve the stability of the rotation of the air-out frame 120. The arc-shaped rack 1541 is preferably disposed at the front side of the gear 153, so as to increase the distance between the meshing point of the arc-shaped rack 1541 and the gear 153 and the pivot axis 141, and reduce the driving force required for driving the air-out frame 120 to move, thereby reducing the reaction force applied to the gear 153 and prolonging the service life of the gear 153.

In the prior art, the driving device 150 that drives the air-out frame 120 to move by using the rack 153 of the gear 153 is to fix the driving motor 152 that drives the gear 153 to rotate, and the rack is fixedly connected with the air-out frame 120 and drives the air-out frame 120 to move, but because the size of the rack is large, the processing defects and the deformation generated after long-time work of the rack can cause the air-out frame 120 to move unstably. The inventor of the application creatively fixedly connects the rack with the shell 110, and fixedly connects the driving motor 152 for driving the gear 153 to rotate with the air outlet frame 120, and makes the movement of the air outlet frame 120 more stable by utilizing the characteristics of small size, short movement stroke and easier control of processing precision of the gear 153.

In some embodiments, the guide 154 may include a mounting plate 1542 and a curved rack 1541 for fixed connection with one lateral sidewall of the housing 110. The arc-shaped rack 1541 may be disposed to extend from the mounting plate 1542 in a direction close to the air-out frame 120, and its surface perpendicular to the mounting plate 1542 is formed with teeth. The surface of the mounting plate 1542 facing away from the curved rack 1541 has at least one locating projection 1542 a. The housing 110 may be correspondingly formed with at least one positioning hole 115, and the at least one positioning protrusion 1542a may be configured to cooperate with the at least one positioning hole 115, respectively, to facilitate the installation and positioning of the guide 154. Further, positioning holes 115 may be provided through lateral sidewalls of the housing 110.

The number of the positioning protrusions 1542a is preferably plural, for example, two, three or more, to improve the stability of the guide 154.

In order to avoid the phenomenon that the gear 153 is excessively engaged with the arc-shaped rack 1541 or even is jammed due to the thermal expansion of the air-out frame 120, in some embodiments, the pivot hole 1221 may be configured to move in a radial direction of the pivot shaft 141 relative to the pivot shaft 141, so as to achieve the automatic adjustment of the position of the gear 153. In some preferred embodiments, the pivot hole 1221 may be oblong, and the transverse dimension of the pivot hole 1221 may be equal to the diameter of the pivot shaft 141, so as to improve the stability of the rotation of the outlet frame 120. The pivot hole 1221 may be further configured such that the longitudinal central plane thereof passes through the rotation axis of the gear 153 and the axis of the pivot shaft 141, so as to prevent the wind-out frame 120 from being jammed during the movement. The pivot hole 1221 may be disposed to leave a play clearance of 2 to 3mm, for example, 2mm, 2.5mm, or 3mm, from the pivot shaft 141 in a direction in which it approaches the gear 153 and a direction in which it separates from the gear 153, respectively. In some alternative embodiments, the pivot hole 1221 may be circular, and the aperture of the pivot hole 1221 is larger than the diameter of the pivot shaft 141.

Fig. 17 is a schematic side view of the air guide member 100 shown in fig. 7, with the cover plate and the mounting plate 1542 removed to show the fitting structure of the guide 154 and the housing 110. Referring to fig. 17, in other embodiments, the guide 154 may be configured to be moveable relative to the pivot shaft 141 in a radial direction of the pivot shaft 141 to automatically accommodate changes in the position of the gear 153. In some preferred embodiments, the length direction of the positioning hole 115 may be disposed to be parallel to a plane passing through the geometric center of the arc-shaped rack 1541 and the axis of the pivot shaft 141, and the at least one positioning protrusion 1542a may be disposed to be movable in the length direction of the positioning hole 115. The peripheral wall of the positioning projection 1542a may be disposed to leave a play gap of 2 to 3mm, for example, 2mm, 2.5mm, or 3mm, with the hole wall of the positioning hole 115 in a direction approaching the pivot shaft 141 and a direction away from the pivot shaft 141, respectively. The cross section of the annular protrusion perpendicular to the thickness direction thereof and the positioning hole 115 may be rectangular to increase the contact area between the annular protrusion and the positioning hole 115 and prevent the positioning hole 115 from being deformed. The projection of the fixing projection 1551 in the vertical plane is located completely within the end face of the positioning projection 1542a (the surface of the positioning projection 1542a facing the fixing projection 1551). A surface of the positioning protrusion 1542a facing the fixing protrusion 1551 may be formed with positioning columns 1542b extending outward. A surface of the fixing protrusion 1551 facing the positioning protrusion 1542a may be formed with a positioning opening 1552, and the positioning column 1542b may be configured to cooperate with a peripheral wall of the positioning opening 1552 to facilitate a fixed connection of the positioning protrusion 1542a and the fixing protrusion 1551.

In some further preferred embodiments, the base 151 of the driving device 150 may include a base main body 1511 fixedly connected to the outlet frame 120 and an anti-falling stop 1512 extending from the base main body 1511 in a direction away from the outlet frame 120, and the arc-shaped rack 1541 is disposed between the anti-falling stop 1512 and the gear 153 to prevent the gear 153 from being disengaged from the arc-shaped rack 1541 due to the outlet frame 120 contracting when cooled. Further, the guide 154 may further include ribs 1543 disposed opposite the curved rack 1541. The base 151 may further include a jam-proof stop 1513 extending from the base body 1511 in a direction away from the air-out frame 120, and the arc-shaped rack 1541 and the rib plate 1543 are disposed between the jam-proof stop 1513 and the anti-slip stop 1512 to prevent the gear 153 and the arc-shaped rack 1541 from being excessively engaged to cause a jam phenomenon. A gap of 0.2-0.4 mm, such as 0.2mm, 0.3mm or 0.4mm, is left between the anti-slip stopper 1512 and the arc-shaped rack 1541 in the front-back direction. A gap of 0.2-0.4 mm, such as 0.2mm, 0.3mm or 0.4mm, is left between the anti-blocking stop 1513 and the rib plate 1543 in the front-back direction. The extended ends of the arc-shaped rack 1541 and the rib 1543 may have a limit projection 1544 projecting toward the anti-slip stopper 1512 and the anti-seize stopper 1513, respectively.
