The air conditioner has the functions of refrigeration and heating, and can provide proper indoor temperature for people, so that the air conditioner is widely loved by people. Air conditioner indoor units are generally classified into wall-mounted air conditioner indoor units and floor air conditioner indoor units.

However, when the rotation angle of the cover plate is not maximized, the cover plate may affect the wind direction guided by the wind guide plate, so that the wind direction may not meet the user's expectation.
The following explains a preferable technical scheme of the air conditioner indoor unit of the embodiment of the invention.
Referring first to fig. 1 to 3, fig. 1 is a schematic diagram of an air conditioner indoor unit according to an embodiment of the present invention; fig. 2 is a schematic view of an air outlet of an air conditioner indoor unit according to an embodiment of the present invention in a closed state; fig. 3 is a schematic view of an air outlet of an air conditioner indoor unit according to an embodiment of the present invention in an open state. As shown in fig. 1 to 3, the present embodiment provides an air conditioner internal unit 10, in particular, a wall-mounted air conditioner internal unit 10, which includes: casing 1, apron 2, connecting rod 3 and motor. The surface of the shell 1 is provided with an air inlet and an air outlet 11, the inside of the shell 1 is provided with a heat exchanger, outside air flows into the inside of the shell 1 from the air inlet, and flows into a room from the air outlet 11 after flowing through the heat exchanger for heat exchange so as to adjust the indoor temperature.
Here, it should be noted that the air outlet 11 is disposed on the surface of the casing 1, which should be understood in a broad sense, that is, the air outlet 11 is disposed on the front side wall of the casing 1, especially the position of the front side wall of the casing 1 near the bottom, and the air outlet 11 is disposed at the boundary between the front side wall and the bottom wall of the casing 1. The front side wall of the housing 1 refers to a side wall of the housing 1 facing indoors and away from a wall, and the bottom wall of the housing 1 refers to a side wall of the housing 1 facing the ground and parallel to the ground. Specifically, an air deflector (not shown) is disposed at the air outlet 11, and the air deflector is rotatably connected to the casing 1 for changing the air outlet direction of the air outlet 11.
The cover plate 2 covers the air outlet 11, the motor is mounted on the inner side wall of the housing 1, the motor shaft is perpendicular to the inner side wall of the housing 1, the first end (i.e. the bottom end in fig. 1) of the connecting rod 3 is in transmission connection with the motor, and the second end (i.e. the top end in fig. 1) of the connecting rod 3 is in fastening connection with the inner surface of the cover plate 2. Therefore, the motor transmits power to the connecting rod 3 to drive the connecting rod 3 to rotate, and further drives the cover plate 2 to move so as to open or close the air outlet 11.
The cover plate 2 is covered on the air outlet 11, which can also be understood in a broad sense, that is, the cover plate 2 can cover the surface of the shell 1 to block the air outlet 11; or, 2 holding of apron are in air outlet 11, and 2 outer fringe of apron and the lateral wall butt of air outlet 11 set up like this, and 2 and the surperficial coplanarity of casing 1 of apron, and whole is more pleasing to the eye.
The first end of the connecting rod 3 can be sleeved on the motor shaft, and the connecting rod 3 rotates along with the motor shaft, so that the moving path of the second end of the connecting rod 3 is a partial arc of a circle which takes the motor shaft as the center of a circle and takes the length of the connecting rod 3 as the radius, and the partial arc is also the moving path of the cover plate 2. In this embodiment, the inner surface of the cover plate 2 and the connecting rod 3 can be firmly connected by welding, clamping, etc. in a manner known to those skilled in the art.
Taking the orientation shown in fig. 1 as an example, when the motor shaft rotates counterclockwise, the connecting rod 3 rotates counterclockwise, so as to drive the cover plate 2 to move toward the outside of the housing 1 and simultaneously drive the cover plate 2 to move upward, so that the air outlet 11 is opened; when the motor shaft rotates clockwise, the movement process is reversed, and will not be described again. It is noted that the link 3 is in an initial state, i.e. in a state of the link 3 when the cover 2 is in the first extreme position (see below), the link 3 is inclined downwards from the first end to the second end.
Preferably, the motor is selected as a stepping motor, and the stepping motor receives the pulse signal and rotates a fixed angle in a set direction so as to control the rotation angle of the connecting rod 3, thereby being capable of controlling the movement path, i.e., the movement track, of the cover plate 2 and avoiding the interference between the cover plate 2 and the housing 1. Moreover, the stepping motor can be self-locked, so that when the cover plate 2 reaches the first limit position or the second limit position, the interference caused by the continuous movement of the cover plate 2 can be avoided. The first limit position refers to a position where the cover plate 2 covers the air outlet 11, and the second limit position refers to a position where the cover plate 2 can reach and the air outlet 11 is completely opened.
In summary, the air conditioner internal unit 10 provided by this embodiment moves through the motor driving connecting rod 3 fastened on the inner side wall of the casing 1, and then drives the cover plate 2 to move along the preset movement track to the casing 1, specifically, the movement track may be that the cover plate moves upward while moving outward, so as to open the air outlet 11. Because the air-out direction of the wall-mounted air conditioner indoor unit is usually obliquely downward, when the cover plate 2 moves upward along an oblique direction to open the air outlet 11, the air flow blocking effect of the air outlet 11 towards the obliquely downward direction is small, and the requirements of users can be basically met.
With continued reference to fig. 1, the air conditioner internal unit 10 may further include a transmission mechanism 4, and the transmission mechanism 4 is configured to transmit power of the motor to the connecting rod 3 to drive the connecting rod 3 to rotate. Thus, if the transmission mechanism 4 is a reduction gear (e.g., a belt transmission mechanism or a chain transmission mechanism), the accuracy of controlling the movement of the cover 2 is improved by a large reduction ratio. The transmission mechanism 4 can be implemented in various ways, and several exemplary embodiments are described below:
in one realizable manner, the transmission mechanism 4 includes a driving gear, a driven gear, and a rotating shaft; the driving gear suit is on the motor shaft of motor, and driven gear suit is in the axis of rotation, and the axis of rotation is connected with the inside wall of casing 1, and the axis perpendicular to casing 1's of axis of rotation lateral wall sets up, driving gear and driven gear meshing, the first end and the axis of rotation fastening connection of connecting rod 3. The gear transmission mechanism is used for transmitting power, the transmission is stable, the transmission ratio is accurate, and the cover plate 2 can move stably.
As shown in fig. 1, in another realisation, the transmission mechanism 4 comprises a driving gear 41 and a rack 42; the driving gear 41 is sleeved on a motor shaft of the motor, and the rack 42 is longitudinally arranged and meshed with the driving gear 41; the first end of the connecting rod 3 is hinged with the rack 42. The power is transmitted by the gear rack transmission mechanism, the work is stable, and compared with a belt transmission mechanism and a chain transmission mechanism, the structure is compact, and the occupied space is small. Also, the rack 42 arranged longitudinally moves up and down by engagement with the driving gear 41 to increase the up-and-down movement speed of the cover 2, thereby enabling the air outlet 11 to be opened or closed quickly.
As shown in fig. 1, the side of the rack gear 42 engaged with the driving gear 41 may be provided with an upper stopper 8 and a lower stopper 9, and the driving gear 41 is located between the upper stopper 8 and the lower stopper 9. Therefore, the upper limit block 8 and the lower limit block 9 can prevent the driving gear 41 from rotating, and further can prevent the rack 42 from continuously moving upwards, so that the cover plate 2 stops moving after reaching the second limit position, at this time, the air outlet 11 is in a fully opened state, or prevent the rack 42 from continuously moving downwards, so that the cover plate 2 stops moving after reaching the first limit position, at this time, the air outlet 11 is in a closed state.
Of course, the present invention is not limited thereto, and in an alternative example of the present invention, only a part of teeth is formed on the side of the rack gear 42 engaged with the driving gear 41, and grooves or flat surfaces are formed on both sides of the teeth, so that when the driving gear 41 is engaged to the groove position or the flat position, the driving gear 41 is no longer engaged with the rack gear 42, so that the rack gear 42 stops moving.
Referring to fig. 4 and 5, fig. 4 is a schematic diagram of another air conditioner internal unit 10 according to an embodiment of the present invention; fig. 5 is a partially enlarged view of a portion a in fig. 4. In order to further improve the control precision and/or stability of the movement path of the cover plate 2, the air conditioner 10 further includes a main support plate 5 in this embodiment, a sliding groove 6 is formed on the inner side wall of the casing 1, one end of the main support plate 5 is fastened and connected with the inner surface of the cover plate 2, the other end of the main support plate 5 is hinged to the second end of the connecting rod 3, and the main support plate 5 and the hinge shaft of the connecting rod 3 are slidably arranged in the sliding groove 6. Due to the arrangement, on one hand, the main supporting plate 5 plays a supporting role for the cover plate 2, so that the connecting rod 3 can more stably drive the cover plate 2 to move; on the other hand, when the motor drives the connecting rod 3 to rotate, the main support plate 5 connected with the hinge shaft moves along the sliding groove 6 because the hinge shaft of the main support plate 5 and the connecting rod 3 is slidably arranged in the sliding groove 6, so that the cover plate 2 moves along the track of the sliding groove 6.
It should be noted that, when the transmission mechanism 4 is a gear transmission mechanism, the track of the sliding slot 6 is the same as the moving path of the second end of the connecting rod 3, so as to prevent the moving path of the connecting rod 3 from colliding with the track of the sliding slot 6, which results in movement jamming. When the transmission mechanism 4 is a gear rack transmission mechanism, the shape of the chute 6 is reasonably set, so that the cover plate 2 which moves to the second limit position along the track of the chute 6 is close to the surface of the shell 1 as much as possible, and the attractiveness of the air conditioner indoor unit 10 is improved.
Illustratively, the sliding groove 6 may be an inclined line groove, the top end of which is closer to the cover plate 2 than the bottom end of the inclined line groove, that is, the inclined line groove extends obliquely upward from the bottom end to the top end thereof. So set up, the shape of spout 6 is simple, the processing of being convenient for. When the air outlet device is used, the driving gear 41 rotates to drive the rack 42 to move up and down, and the connecting rod 3 moves in the inclined linear groove along with the rack, so that the cover plate 2 moves outwards while moving upwards, and the air outlet 11 is exposed.
When the cover plate 2 is located at the first limit position, the hinged shaft is arranged at the bottom end of the inclined wire groove in a sliding mode, and when the cover plate 2 is located at the second limit position, the hinged shaft can be arranged at the top end of the inclined wire groove in a sliding mode or located between the top end and the bottom end.
With continued reference to fig. 4 and 5, of course, the present invention is not limited thereto, and the chute 6 may further include a first section 61 and a second section 62 communicating with each other, the first section 61 being disposed away from the cover 2 with respect to the second section 62, and a junction of the first section 61 and the second section 62 being smoothly transitioned. The first section 61 is obliquely arranged and used for guiding the cover plate 2 to move towards the outer side of the shell 1 in the early stage of opening and guiding the cover plate 2 to move towards the inner side of the shell 1 in the later stage of closing; a second section 62 for guiding the cover 2 up and down in the later stage of opening or the earlier stage of closing. Through the arrangement, the cover plate 2 can move towards the outer side or the inner side of the shell 1 and move up and down along a definite track through reasonable design.
Alternatively, the second section 62 may be disposed obliquely, so that the cover 2 moves toward the outside of the housing 1 while moving upward in the later stage of opening and moves toward the inside of the housing 1 while moving downward in the earlier stage of closing under the guiding action of the second section 62. Here, the inclination angle of the second segment 62 may be different from that of the first segment 61, or may be the same, and when the inclination angle of the second segment 62 is the same as that of the first segment 61, the first segment 61 and the second segment 62 together constitute an inclined line groove.
Alternatively, when the air outlet 11 is formed at a position near the bottom of the front side wall of the housing 1, the front side wall of the housing 1 being a vertical plane, the second section 62 is a vertical groove section. So set up, the central line of the second section 62 of spout 6 is on a parallel with casing 1, then follow 6 second sections 62 of spout and reciprocate apron 2 can be better in the later stage of opening press close to casing 1, improved the aesthetic property of air conditioner internal unit 10 in the state of opening, visual effect is good.
