[0039] The air conditioner (not shown in the figure) proposed in this embodiment of the invention includes a control device and an indoor unit. For example... Figures 1 to 3 As shown, the indoor unit includes a body 100 with an air outlet 110 and an air guide plate assembly 200, the air guide plate assembly 200 being disposed at the air outlet 110. Figures 1 to 4 As shown, the air guide plate assembly 200 includes: N air guide plates 210, which are sequentially arranged in a first direction; and N motors 220, which are connected to the N air guide plates 210 in a one-to-one transmission manner, and drive the N air guide plates 210 to swing in a one-to-one manner. A control device is electrically connected to the N motors 220 to control the N motors 220. The output shaft of each motor 220 is located in a direction that intersects with the first direction (i.e., not parallel or collinear), and N ≥ 2.

[0040] The air conditioner's air guide plate assembly 200 includes N air guide plates 210 and N motors 220. The N air guide plates 210 are arranged sequentially in the first direction, and the N motors 220 are connected to the N air guide plates 210 in a one-to-one transmission manner. The axis of the output shaft of each motor 220 intersects the first direction, meaning that the N motors 220 are not arranged sequentially in the first direction. The N motors 220 control the N air guide plates 210 in a one-to-one manner, that is, the N motors 220 control the N air guide plates 210 respectively. This makes the air outlet 110 more versatile and can further improve the air blowing experience of the indoor unit.

[0041] In one exemplary embodiment, such as Figures 1 to 5 As shown, adjacent air guide plates 210 are hinged together, so that N air guide plates 210 form a combined structure. Through the cooperation of N air guide plates 210, the air guiding effect of the air guide plates is better, and the air outlet 110 has a more diversified air outlet mode.

[0042] Alternatively, adjacent air guide plates can be independent of each other, and N motors can be fixed on the outlet wall; or the output shaft of each motor 220 can be along the second direction, and one end of each air guide plate in the second direction can be connected to a motor for transmission, and the other end in the second direction can be hinged to the outlet wall of the air outlet 110. This can also achieve the purpose of this application. Its purpose has not departed from the design concept of this invention, and will not be elaborated here. It should also fall within the protection scope of this application.

[0043] In one exemplary embodiment, such as Figures 1 to 5 As shown, the axis of the output shaft of each motor 220 is along the second direction, and the second direction is preferably perpendicular to the first direction. This design makes the air guide plate assembly 200 more neat and aesthetically pleasing.

[0044] Of course, the air outlet 110 and the air guide plate 210 can also be designed as parallelograms or irregular shapes, etc. In this case, the second direction and the first direction may not be perpendicular, but the purpose of this application can still be achieved. The purpose has not deviated from the design concept of this invention, and will not be elaborated here. It should also fall within the protection scope of this application.

[0045] In one exemplary embodiment, the first direction is the width direction of the air guide plate 210, such as... Figure 1 and Figure 3 As shown, the second direction is the length direction a of the air guide plate 210, and the length direction a of the air guide plate 210 is parallel to the horizontal plane.

[0046] In one exemplary embodiment, such as Figures 1 to 4 As shown, N air guide plates 210 include a first air guide plate 211 and a second air guide plate 212 arranged sequentially in a first direction. The first air guide plate 211 is located above the second air guide plate 212, and the second end of the first air guide plate 211 is opposite to the first end of the second air guide plate 212. Moreover, the second end of the first air guide plate 211 and the first end of the second air guide plate 212 are hinged together. N motors 220 include a first motor 221 and a second motor 222, which are arranged sequentially in a second direction. The first air guide plate 211 and the second air guide plate 212 are located between the first motor 221 and the second motor 222 in the second direction. The output shaft of the first motor 221 is driven to the second end of the first air guide plate 211, and the first motor 221 is used to drive the first air guide plate 211 to swing. The output shaft of the second motor 222 is driven to the first end of the second air guide plate 212, and the second motor 222 is used to drive the second air guide plate 212 to swing.

[0047] In one example, such as Figure 4 and Figure 5As shown, the second end of the first air guide plate 211 is provided with a first protrusion 2111 and a first notch 2112 arranged sequentially in a second direction. The first end of the second air guide plate 212 is provided with a second notch 2121 and a second protrusion 2122 arranged sequentially in a second direction. The first protrusion 2111 corresponds to the second notch 2121, and the second protrusion 2122 corresponds to the first notch 2112. The first protrusion 2111 is placed inside the second notch 2121, and the second protrusion 2122 is placed inside the first notch 2112. The second protrusion 2122 and the first protrusion 2111 are hinged together by a first hinge structure 230, that is, the second end of the first air guide plate 211 and the first end of the second air guide plate 212 are hinged together. The first motor 221 and the second motor 222 are both located inside the main body 100. The first motor 221 is fixed to one wall of the air outlet 110 in the second direction and is driven by the first protrusion 2111, thereby driving the first air guide plate 211 to swing. The second motor 222 is fixed to the other wall of the air outlet 110 in the second direction and is driven by the second protrusion 2122, thereby driving the second air guide plate 212 to swing. To ensure that the first motor 221 can drive the first air guide plate 211 to rotate relative to the second protrusion 2122, and also to ensure that the second motor 222 can drive the second air guide plate 212 to rotate relative to the first protrusion 2111, the axis of the first hinge structure 230, the axis of the output shaft of the first motor 221, and the axis of the output shaft of the second motor 222 should be designed to be collinear.

[0048] Alternatively, the first hinge structure 230 may include a hinge convex shaft and a hinge shaft hole, with one of the hinge convex shaft and the hinge shaft hole located in the first protrusion 2111 and the other in the second protrusion 2122; or it may be, as... Figure 4 As shown, the first hinge structure 230 includes two hinge protrusions and a connecting sleeve. One of the two hinge protrusions is located in the first protrusion 2111 and the other is located in the second protrusion 2122. The connecting sleeve is located between the first protrusion 2111 and the second protrusion 2122 and is sleeved on the two hinge protrusions. All of the above can achieve the purpose of this application. The purpose has not departed from the design concept of this invention, and will not be repeated here. All of them should fall within the protection scope of this application.

[0049] In one exemplary embodiment, such as Figures 1 to 5As shown, the N air guide plates 210 also include a third air guide plate 213, which is located on the side of the second air guide plate 212 facing away from the first air guide plate 211, that is, the second air guide plate 212 is located between the first air guide plate 211 and the third air guide plate 213. The first end of the third air guide plate 213 is opposite to the second end of the second air guide plate 212, and the first end of the third air guide plate 213 and the second end of the second air guide plate 212 are hinged together. The N motors 220 also include a third motor 223, which is fixed to the second end of the second air guide plate 212 and is drivenly connected to the first end of the third air guide plate 213. The third motor 223 is used to drive the third air guide plate 213 to swing relative to the second air guide plate 212.

[0050] In one example, such as Figure 4 and Figure 5 As shown, the second end of the second air guide plate 212 is provided with a third protrusion 2123, a third notch 2124, and a fourth protrusion 2125 arranged sequentially in the second direction. The first end of the third air guide plate 213 is provided with a fourth notch 2131, a fifth protrusion 2132, and a fifth notch 2133 arranged sequentially in the second direction. The third protrusion 2123 corresponds to the fourth notch 2131, the fifth protrusion 2132 corresponds to the third notch 2124, and the fourth protrusion 2125 corresponds to the fifth notch 2133. The third protrusion 2123 is placed in the fourth notch 2131, the fifth protrusion 2132 is placed in the third notch 2124, and the fourth protrusion 2125 is placed in the fifth notch 2133. The fifth protrusion 2132 and the fourth protrusion 2125 are hinged together by the second hinge structure 240, which means that the first end of the third air guide plate 213 and the second end of the second air guide plate 212 are hinged together. The third motor 223 is fixed to the third protrusion 2123 and is connected to the fifth protrusion 2132 for transmission, so that the third motor 223 drives the third air guide plate 213 to swing around the fourth protrusion 212. In order to ensure that the third motor 223 can drive the third air guide plate 213 to rotate around the fourth protrusion 2125, the axis of the second hinge structure 240 and the axis of the output shaft of the third motor 223 should be collinear. Alternatively, the fifth protrusion 2132 and the third protrusion 2123 can be hinged together by the second hinge structure 240, and the third motor 223 can be fixed to the fourth protrusion 2125 and connected to the fifth protrusion 2132 for transmission. This can also achieve the purpose of this application. Its purpose has not departed from the design concept of this invention, and will not be elaborated here. It should also fall within the protection scope of this application.

[0051] Alternatively, the second hinge structure 240 may include a hinge convex shaft and a hinge shaft hole, with one of the hinge convex shaft and the hinge shaft hole located in the fourth protrusion 2125 and the other in the fifth protrusion 2132; or it may be, as... Figure 4As shown, the second hinge structure 240 includes two hinge protrusions and a connecting sleeve. One of the two hinge protrusions is located in the fourth protrusion 2125 and the other is located in the fifth protrusion 2132. The connecting sleeve is located between the fourth protrusion 2125 and the fifth protrusion 2132 and is sleeved on the two hinge protrusions. All of the above can achieve the purpose of this application. The purpose has not departed from the design concept of this invention, and will not be repeated here. All of them should fall within the protection scope of this application.

[0052] In one example, such as Figure 1 and Figure 4 As shown, the second motor 222 and the third motor 223 are located on one side of the second air guide plate 212, and the first motor 221 is located on the other side of the second air guide plate 212. Furthermore, the output shaft of the second motor 222 is connected to the second protrusion 2122 via a bushing 250. Wherein, as... Figures 4 to 6 As shown, the side wall of the bushing 250 is provided with a wire passage 251, which is located in the outer area of ​​the second air guide plate 212. The second air guide plate 212 is provided with a wire passage hole. The wire passage 251, the interior of the bushing 250 and the wire passage hole form a wire passage channel. The connecting wire 2231 of the third motor 223 passes through the wire passage hole and the interior of the bushing 250 in sequence, and then extends out of the bushing 250 from the wire passage 251 to be electrically connected to the control device. The connecting wire 2231 of the third motor 223 is hidden, which is not only aesthetically pleasing, but also prevents the problem of wire jamming.

[0053] In one embodiment, such as Figure 4 , Figure 5 and Figure 7As shown, the second air guide plate 212 includes a plate body 2126 and a pressure cover 2127. The plate body 2126 and the pressure cover 2127 are arranged sequentially in the second direction. The pressure cover 2127 is located between the second motor 222 and the plate body 2126 in the second direction. The fourth notch 2131, the fifth protrusion 2132 and the fifth notch 2133 are all located on the plate body 2126. The third motor 223 is installed on the plate body 2126. The pressure cover 2127 is installed on one end of the plate body 2126 in the second direction and covers the third motor 223. The pressure cover 2127 and the plate body 2126 together form a wire passage hole. The plate 2126 has a wiring groove 2128 on its side, which extends to the third protrusion 2123. The opening of the wiring groove 2128 on the third protrusion 2123 faces the third motor 223. The bushing 250 is inserted into the through end of the wiring groove 2128 on the third protrusion 2123 along the second direction. The pressure cap 2127 abuts against the side of the bushing 250 in the first direction and blocks the opening of the wiring groove 2128 (one end of the pressure cap 2127 that cooperates with the bushing 250 has a concave arc surface 2129). This can help the second motor 222 to position the bushing 250 and prevent the bushing 250 from coming out of the wiring groove 2128. The wiring groove 2128 and the pressure cover 2127 form a wiring hole, and the wiring groove 2128, the pressure cover 2127 and the bushing 250 together form a wiring channel, making the wiring operation of the connection line 2231 of the third motor 223 simpler and faster.

[0054] In one example, such as Figures 1 to 3 As shown, the air outlet 110 includes a first region 111 and a second region 112. The first region 111 is located above the second region 112. A first air guide plate 211 corresponds to the first region 111. When the indoor unit is off, the first air guide plate 211 closes the first region 111. At this time, the lower end of the first air guide plate 211 is the second end of the first air guide plate 211, and the upper end of the first air guide plate 211 is the first end of the first air guide plate 211. The second air guide plate 212 and the third... The air guide plate 213 corresponds to the second area 112. When the indoor unit is turned off, the second air guide plate 212 and the third air guide plate 213 together close the second area 112. At this time, the lower end of the second air guide plate 212 is the second end of the second air guide plate 212, and the upper end of the second air guide plate 212 is the first end of the second air guide plate 212. The lower end of the third air guide plate 213 is the second end of the third air guide plate 213, and the upper end of the third air guide plate 213 is the first end of the third air guide plate 213.

[0055] like Figures 1 to 5 As shown, N motors 220 are actually 3 motors, namely the first motor 221, the second motor 222, and the third motor 223.

[0056] Of course, N motors 220 can also be 4 motors, 5 motors, or 6 motors, etc., all of which can achieve the purpose of this application. Their purpose has not departed from the design concept of this invention, and will not be elaborated here. They should all fall within the protection scope of this application.

[0058] The air conditioner control method proposed in this embodiment of the invention (not shown in the figure) includes: controlling N motors 220 to adjust N air guide plates 210 respectively through a control device, thereby adjusting the air outlet direction of the air outlet 110.

[0059] The control method of this air conditioner includes an air guide plate assembly 200 comprising N air guide plates 210 and N motors 220. The N air guide plates 210 are arranged sequentially in a first direction, and the N motors 220 are connected to the N air guide plates 210 in a one-to-one transmission manner. The axis of the output shaft of each motor 220 intersects with the first direction, meaning that the N motors 220 are not arranged sequentially in the first direction. The N motors 220 control the N air guide plates 210 in a one-to-one manner. That is, the control device controls the N motors 220 to adjust the N air guide plates 210 respectively, thereby adjusting the air outlet direction of the air outlet 110. This makes the air outlet 110 more versatile and can further improve the air blowing experience of the indoor unit.

[0060] In an exemplary embodiment, the step of adjusting the air outlet 110 by controlling N motors 220 to adjust N air guide plates 210 respectively through a control device includes: Figure 1As shown, in the first operating mode, the control device controls the first motor 221, the second motor 222, and the third motor 223 to make the first air guide plate 211, the second air guide plate 212, and the third air guide plate 213 coplanar and tilted at a first set angle relative to the air outlet 110. The first operating mode can be set to a normal cooling mode or a normal heating mode. Alternatively, the control device can stop the third motor 223 and control the first motor 221 and the second motor 222 to operate synchronously, thereby achieving the coplanarity of the first air guide plate 211, the second air guide plate 212, and the third air guide plate 213. Alternatively, the first air guide plate 211 can be located above the second air guide plate 212 and the third air guide plate 213, and tilted downwards and outwards from the first air guide plate 211 to the third air guide plate 213, so that both the first region 111 and the second region 112 are tilted downwards and blowing air. It can be a fixed blower (i.e., the first motor 221 and the second motor 222 rotate synchronously at a set angle and then be fixed at a set position), or it can be a swing blower (i.e., the first motor 221 and the second motor 222 swing back and forth within a set angle range). Both can achieve the purpose of this application. Their purpose has not departed from the design concept of this invention, and will not be elaborated here. Both should fall within the protection scope of this application.

[0061] In an exemplary embodiment, the step of adjusting the air outlet 110 by controlling N motors 220 to adjust N air guide plates 210 respectively through a control device includes: Figure 2As shown, in the second working mode, the control device controls the first motor 221, the second motor 222, and the third motor 223 to close the first area 111 with the first air guide plate 211, tilt the second air guide plate 212 relative to the second area 112 at a second set angle, and tilt the third air guide plate 213 relative to the second air guide plate 212 at a third set angle. The second working mode can be set to a long-distance heating and air delivery mode. Specifically, the control device can stop the first motor 221, and control the second motor 222 and the third motor 223 to operate respectively. This achieves the following: the first air guide plate 211 closes the first area 111; the second air guide plate 212 tilts downwards towards the air outlet 110 relative to the second area 112 at a second set angle; and the third air guide plate 213 tilts downwards relative to the second air guide plate 212 at a third set angle. This allows hot air to be blown downwards from the second area 112 towards the ground, achieving carpet-like auxiliary heating. This solution allows for a long-distance hot air delivery. The air blower can be a fixed air blower (i.e., the second motor 222 and the third motor 223 rotate at corresponding angles and then be fixed at a set position), or it can be an oscillating air blower (the second motor 222 can oscillate back and forth within a corresponding angle range, or the third motor 223 can oscillate back and forth within a corresponding angle range, or the second motor 222 and the third motor 223 can oscillate back and forth within a corresponding angle range respectively). Both can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention. They will not be elaborated here, and should all fall within the protection scope of this application.

[0062] In an exemplary embodiment, the step of adjusting the air outlet 110 by controlling N motors 220 to adjust N air guide plates 210 respectively through a control device includes: Figure 3 As shown, in the third working mode, the control device controls the first motor 221, the second motor 222, and the third motor 223 to tilt the first air guide plate 211 relative to the first region 111 at a fourth predetermined angle, and to close the second region 112 with the second air guide plate 212 and the third air guide plate 213. The third working mode can be set to a long-distance cooling and air delivery mode. Alternatively, the control device can control the first motor 221 to operate, and control the second motor 222 and the third motor 223 to stop, so that the first air guide plate 211 tilts outward and upward at a fourth predetermined angle relative to the first region 111, and the second air guide plate 212 and the third air guide plate 213 close the second region 112, causing cold air to be blown upward from the first region 111 at an angle, achieving waterfall-style cooling. This scheme allows for a long-distance cold air delivery. It can be a fixed blower (i.e., the first motor 221 rotates to a corresponding angle and then is fixed at a set position) or an oscillating blower (the first motor 221 can oscillate back and forth within a corresponding angle range). Both can achieve the purpose of this application. Their purpose has not departed from the design concept of this invention, and will not be elaborated here. Both should fall within the protection scope of this application.

The N air deflectors are arranged in sequence in the first direction, and the N motors are in one-to-one transmission connection with the N air deflectors. The direction of the axis of the output shaft of each motor intersects with the first direction, that is, the N motors are not arranged in sequence in the first direction. The N motors control the N air deflectors one by one, that is, the N motors respectively control the N air deflectors. This air deflector assembly is applied to the indoor unit, and the air outlet mode is more diversified, which can further improve the blowing feeling of the indoor unit.
