[0043] Figure 1 FIG. 1 is a schematic partial structural diagram of an indoor unit of an air conditioner according to an embodiment of the present utility model. Figure 1 As shown, and refer to Figures 2 to 6 The embodiment of the utility model provides an indoor unit 100 of an air conditioner, comprising an air outlet duct and at least two air guide plates. The air outlet duct has an air outlet 160 extending in a transverse direction, and the upper wall surface of the air outlet duct comprises a first air guide section 111, and a first clearance section 112 arranged between the first air guide section 111 and the air outlet 160. At least two air guide plates are sequentially arranged at the air outlet 160 along the width direction of the air outlet 160, and are configured to close the air outlet 160. Each air guide plate is rotatably arranged around an axis extending in a transverse direction. The uppermost air guide plate is the first air guide plate 120, and the first clearance section 112 is configured to allow the upper edge of the first air guide plate 120 to rotate to the connection between the first air guide section 111 and the first clearance section 112.

[0044] In the indoor unit 100 of the air conditioner of the embodiment of the utility model, when the indoor unit 100 of the air conditioner is discharging air, the air guide plate closing the air outlet 160 rotates, so that the air outlet 160 is in an open state, or in other words, the air outlet passage 110 is connected to the room. When the air outlet 160 is discharging air downward, the air guide plate rotates so that the lower edge of the air guide plate faces downward, and the upper edge of the air guide plate is in the air outlet passage 110. And the first air guide plate 120 on the uppermost side rotates, and its upper edge is at the connection between the first air guide section 111 and the first yield section 112, so that the wind passing through the first air guide section 111 in the air outlet passage 110 is blown downward from the first air guide section 111 to the first air guide plate 120, and then passes through the first air guide plate 120. When the air outlet 160 is to discharge air upward, the air guide plate rotates so that the upper edge of the air guide plate faces upward, and the lower edge of the air guide plate is in the air outlet passage 110. The wind passing through the first air guide section 111 in the air outlet channel 110 passes through the first clearance section 112 and is finally guided upward by the first air guide plate 120. When the air outlet 160 discharges air downward, the upper edge of the first air guide plate 120 can pass through the first clearance section 112 to the connection between the first clearance section 112 and the first air guide section 111, that is, the space of the first clearance section 112 is relatively large. No matter what upward tilt angle the first air guide plate 120 is at, the smoothness of the air outlet is not affected.

[0045] The first air guide section 111 and the first clearance section 112 are arranged so that when the air outlet 160 discharges air downward, the upper edge of the first air guide plate 120 enters the first clearance section 112, thereby reducing the influence of the first air guide plate 120 on the air discharge, which is more conducive to the downward air guide. Also, when the air outlet 160 discharges air upward, the upper edge of the first air guide plate 120 is closer to the upper edge of the air outlet 160, and the air guide angle is more upward, and the air volume is sufficiently large here, which ultimately increases the air discharge efficiency of the air conditioner indoor unit 100.

[0046] In this embodiment, the wind guide plate can be rotated so that part of the wind in the air outlet channel 110 is blown out upward or front upward, front downward or downward.

[0047] In some embodiments of the present invention, Figures 1 to 3 As shown, the first giving way section 112 is an arc surface, and the axis of the arc surface is coaxial with the rotation axis 130 of the first air guide plate. The first air guide plate 120 is in contact with the first giving way section 112 .

[0048] In this embodiment, during the rotation of the first air guide plate 120, when the upper edge of the first air guide plate 120 reaches the position of the first clearance section 112, the upper edge of the first air guide plate 120 will contact the surface of the first clearance section 112. In other words, when the first air guide plate 120 closes the corresponding position of the air outlet 160 or the air outlet 160 discharges air downward, the upper edge of the first air guide plate 120 is always in contact with the surface of the first clearance section 112, so that the air in the air outlet channel 110 will not flow upward, and the air outlet direction is accurately determined while the airtightness is increased.

[0049] Of course, the user can adjust the air outlet direction of the air outlet 160 by adjusting the position of the upper edge of the first air guide plate 120 in the first clearance section 112. For example, if the user wants the air outlet direction to be vertically downward, then the upper edge of the first air guide plate 120 should be closer to the outer end of the first clearance section 112. In other words, when the air outlet 160 is discharging air downward, the higher the air outlet position is, the closer the upper edge of the first air guide plate 120 is to the connection between the first clearance section 112 and the first air guide section 111.

[0050] In some embodiments of the present invention, Figures 1 to 3 As shown, the connection between the first air guide section 111 and the first clearance section 112 is located at the rear lower side of the upper edge of the air outlet 160. The connection between the first air guide section 111 and the first clearance section 112 is located at the front upper side of the lower edge of the air outlet 160, or the connection between the first air guide section 111 and the first clearance section 112 is located just above the lower edge of the air outlet 160. The upper edge of the air outlet 160 is located at the front upper side of the lower edge of the air outlet 160.

[0051] In this embodiment, the first air guide section 111 and the first clearance section 112 are located in the upper half of the air outlet channel 110. Since the connection between the first air guide section 111 and the first clearance section 112 is located at the front upper side or directly in front of the air outlet 160, that is, the first clearance section 112 is always located at the front upper side of the lower edge of the air outlet 160. Therefore, the angle between the width direction of the air outlet 160 and the horizontal plane is less than 90°, that is, when the air guide plate closes the air outlet 160, the air guide plate is also inclined, which is conducive to the mutual rotation between the first air guide plate 120 and the second air guide plate 140.

[0052] In some embodiments of the utility model, the lower wall surface of the air outlet duct includes a second air guide section and a second clearance section disposed between the second air guide section and the air outlet 160. The lowermost air guide plate is the second air guide plate 140, and the second clearance section is configured to allow the rear edge of the second air guide plate 140 to rotate to the connection between the second air guide section and the second clearance section.

[0053] In this embodiment, when the air outlet 160 guides the air upward, the lower edge of the second air guide plate 140 at the lowest side rotates to the connection between the second air guide section and the second yield section, and the upper edge of the second air guide plate 140 extends upward from the air outlet 160. The wind of the air outlet channel 110 passing through the second air guide section reaches the second air guide plate 140 through the second air guide section, and then blows upward along the second air guide plate 140. In other words, when the air outlet 160 discharges the air upward, the second air guide plate 140 at the lowest side does not need to close the lower part of the air outlet 160, and the wind in the lower part of the air outlet channel 110 will be directly blown upward through the second air guide plate 140, and the air outlet area of ​​the air outlet 160 will not be reduced, which further ensures the air outlet efficiency.

[0054] In this embodiment, the second air guide plate 140 can be rotated to allow part of the wind in the air outlet channel 110 to be blown out upward or front upward, front downward, or downward.

[0055] In some embodiments of the present invention, the second yielding section is an arc-shaped surface, and the axis of the arc-shaped surface is coaxial with the rotation axis 130 of the first air guide plate. The second air guide plate 140 contacts the second yielding section.

[0056] In this embodiment, during the rotation of the second air guide plate 140, when the second air guide plate 140 reaches the position of the second yielding section, the upper edge of the second air guide plate 140 will contact the surface of the second yielding section. In other words, when the second air guide plate 140 closes the corresponding position of the air outlet 160 or the air outlet 160 discharges air upward, the upper edge of the second air guide plate 140 is always in contact with the surface of the second yielding section, so that the air in the air outlet channel 110 will not flow out, thereby improving the airtightness.

[0057] Of course, the user can adjust the air outlet direction of the air outlet 160 by adjusting the position of the upper edge of the second wind shield to the second clearance section. That is to say, when the air outlet 160 is discharging air upward, the lower the air outlet position is, the closer the lower edge of the second air guide plate 140 is to the connection between the second clearance section and the second air guide section.

[0058] In some embodiments of the present invention, Figure 1 As shown, the air guide plate has a preset position, in which, when the angle between the tangent plane of the upper end of the inner surface of the first air guide plate 120 and the horizontal plane is within 10°, the angle between the tangent plane of the rear end of the inner surface of the second air guide plate 140 and the horizontal plane is greater than 80°. And the upper edge of the second air guide plate 140 contacts the first air guide plate 120.

[0059] It can be seen from the above embodiment that the first air guide plate 120 is located at the uppermost position, and the second air guide plate 140 is located at the lowermost position. In this embodiment, when the angle between the cut surface of the upper end of the inner surface of the first air guide plate 120 and the horizontal plane is within 10°, the upper wind of the air outlet channel 110 will be blown out horizontally through the first air guide plate 120. At this time, the angle between the cut surface of the rear end of the inner surface of the second air guide plate 140 and the horizontal plane is greater than 80°, and the lower half of the wind of the air outlet duct will be blown out vertically downward through the second air guide plate 140. And at this time, the upper edge of the second air guide plate 140 is in contact with the first air guide plate 120, so that the wind of the air outlet channel 110 will not be blown out from between the first air guide plate 120 and the second air guide plate 140. That is to say, the air outlet of the air conditioner indoor unit 100 is an encircling wind composed of horizontal wind and vertical downward wind. While ensuring the air outlet efficiency, it avoids the air conditioner indoor unit 100 blowing directly to the indoor position corresponding to the air outlet 160, thereby improving the user experience.

[0060] In some embodiments of the present invention, Figures 1 to 3 As shown, the plane passing through the rotation axis 130 of the first air guide plate and perpendicular to the first air guide plate 120 is the first plane, and the intersection position of the first plane and the first air guide plate 120 is the first position. The vertical here refers to being perpendicular to the first air guide plate 120 or perpendicular to the tangent plane of the first air guide plate 120. The distance from the first position to the lower edge of the first air guide plate 120 is the first distance. The plane passing through the rotation axis 150 of the second air guide plate and perpendicular to the second air guide plate 140 is the second plane, and the intersection position of the second plane and the second air guide plate 140 is the second position. The vertical here refers to being perpendicular to the second air guide plate 140 or perpendicular to the tangent plane of the second air guide plate 140. The distance from the second position to the upper edge of the second air guide plate 140 is the second distance. The distance between the rotation axis 130 of the first air guide plate and the rotation axis 150 of the second air guide plate 140 is the third distance. The sum of the first distance and the second distance is greater than the third distance.

[0061] In this embodiment, since the sum of the first distance and the second distance is greater than the third distance, that is, the sum of the distance from the first position to the lower edge of the first air guide plate 120 and the distance from the second position to the upper edge of the second air guide plate 140 is greater than the distance between the rotation axis 130 of the first air guide plate and the rotation axis 150 of the second air guide plate. When the air guide plate closes the air outlet 160, the lower section of the first air guide plate 120 overlaps with the upper section of the second air guide plate 140. And it can be seen from the above embodiment that the upper edge of the first air guide plate 120 contacts the surface of the first yielding section 112, and the lower edge of the second air guide plate 140 contacts the surface of the second yielding section, that is, at this time, the first air guide plate 120 and the second air guide plate 140 seal the air outlet 160. When the air conditioner indoor unit 100 is not turned on, dust is prevented from entering the air conditioner indoor unit 100 through the air outlet 160.

[0062] In some embodiments of the present invention, Figures 1 to 3 As shown, the ratio between the first distance and the second distance is between 1 and 2. For example, it is set to 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2. More preferably, the ratio between the first distance and the second distance is set between 1.4 and 2. That is, the distance from the first position to the lower edge of the first air guide plate 120 is 1.4 to 2 times the distance from the second position to the upper edge of the second air guide plate 140. That is, the length value of the first air guide plate 120 from the rotation axis 130 of the first air guide plate to the lower edge area of ​​the first air guide plate 120 is greater than the length value of the second air guide plate 140 from the rotation axis 150 of the second air guide plate to the upper edge area of ​​the second air guide plate 140. When the air outlet 160 blows the surrounding wind, the relative movement between the second air guide plate 140 and the first air guide plate 120 is not affected.

[0063] In some embodiments of the present invention, Figure 1 As shown, the first air guide plate 120 and the second air guide plate 140 can work relatively independently.

[0064] In this embodiment, the first air guide plate 120 and the second air guide plate 140 can both rotate independently. The lower edge of the first air guide plate 120 rotates inwardly toward the air outlet 160, and the lower edge of the second air guide plate 140 rotates outwardly toward the air outlet 160. When the upper edge of the second air guide plate 140 contacts the first air guide plate 120, the first air guide plate 120 and the second air guide plate 140 both stop rotating. The wind in the upper half of the air outlet channel 110 is blown out horizontally through the first air guide plate 120, and the wind in the lower half of the air outlet channel 110 is blown out downwardly through the second air guide plate 140 to form the above-mentioned surrounding wind. Of course, the user can achieve different angles of rotation through the first air guide plate 120 and the second air guide plate 140 to make the air outlet area larger or smaller.

[0065] When the air outlet 160 discharges air upward, the user can reduce the air volume by closing the lower half of the air outlet 160 with the second air guide plate 140. Of course, when the air outlet 160 discharges air upward, the user can reduce the air volume by closing the upper half of the air outlet 160 with the first air guide plate 120.

[0066] As can be seen from the above embodiments, both the first air guide plate 120 and the second air guide plate 140 can guide the air upward or downward. Therefore, when the user needs the air outlet 160 to discharge air with a smaller air volume, one of the first air guide plate 120 and the second air guide plate 140 can be controlled separately to guide the air of the air outlet channel 110, and the other air guide plate is in a state of closing the air outlet 160.

[0067] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the air conditioner indoor unit 100 is an air conditioner indoor unit 100 for the bedroom 300, and is installed on the vertical wall of the bedroom 300. Moreover, the air conditioner indoor unit 100 is installed on the upper side of the head of the bed 200 in the bedroom 300, or is installed on the vertical wall of the bedroom 300 that is opposite to the foot of the bed 200. The air outlet 160 of the air conditioner indoor unit 100 is installed opposite to the middle part of the bed 200 along the width direction of the bed 200.

[0068] In this embodiment, the air conditioner indoor unit 100 is installed on a vertical wall, and the air conditioner indoor unit 100 is located above the middle of the head of the bed 200 or above the middle of the foot of the bed 200. It can be seen from the above embodiment that the air outlet 160 of the air conditioner indoor unit 100 can discharge air upward or downward. When the air conditioner indoor unit 100 is at the head of the bed, the air outlet 160 discharges air upward, avoiding the wind from the air outlet channel 110 from blowing directly on the bed 200. When the air conditioner indoor unit 100 is located at the foot of the bed directly opposite to the bed 200 in the bedroom 300, the air outlet 160 discharges air downward, avoiding the wind from the air outlet channel 110 from blowing directly on the bed 200. In other words, the bed 200 is not directly blown by the wind from the air outlet channel 110, which improves the user experience.

[0069] In some embodiments of the present invention, Figures 4 to 6As shown, the air conditioner indoor unit 100 is an air conditioner indoor unit 100 for the bedroom 300, and is arranged on the vertical wall of the bedroom 300. The air conditioner indoor unit 100 also includes a sensor and a control device. The sensor is used to detect the position of the bed 200 in the bedroom 300. The control device is electrically connected to the sensor, and the control device is used to control at least two air guide plates, so that when the sensor detects that the air conditioner indoor unit 100 is located at the head of the bed 200, the at least two air guide plates are controlled to send air horizontally forward and / or forward and upward. And when the sensor detects that the air conditioner indoor unit 100 is located at the foot of the bed 200, the at least two air guide plates are controlled to send air downward and / or front and downward. When the sensor detects that the air conditioner indoor unit 100 is located on one side of the bed 200, at least two air guide plates are controlled to allow part of the air flow to be sent horizontally forward and / or forward and upward, and the remaining part of the air flow is sent downward and / or front and downward.

[0070] In daily life, after the air conditioner indoor unit 100 is installed indoors, it is not easy to be frequently disassembled and assembled, but the indoor layout may change. For example, the position of the bed 200 in the bedroom 300 is not fixed, but the position of the air conditioner indoor unit 100 in the bedroom 300 is basically fixed, in order to keep the air conditioner indoor unit 100 from blowing directly on the bed 200 after the position of the bed 200 changes. In this embodiment, when the sensor detects that the air conditioner indoor unit 100 is located at the head of the bed 200, the control device electrically connected to the sensor controls the first air guide plate 120 and the second air guide plate 140 to send air horizontally forward or forward upward, thereby avoiding the wind from blowing directly on the bed 200. When the sensor detects that the air conditioner indoor unit 100 is located at the foot of the bed, the control device controls the first air guide plate 120 and the second air guide plate 140 to send air downward or front and lower, thereby avoiding the wind from blowing directly on the bed 200. When the sensor detects that the air conditioner indoor unit 100 is located at one side of the bed 200, the control device controls the first air guide plate 120 at the upper position to supply air horizontally forward or forward and upward, and the control device controls the second air guide plate 140 at the lower position to supply air downward or front and lower, thereby preventing wind from blowing directly onto the bed 200.

[0071] Of course, when the sensor detects that the air conditioner indoor unit 100 is located at the head of the bed 200, the first air guide plate 120 and the second air guide plate 140 can also be controlled to send air horizontally forward and forward upward. When the sensor detects that the air conditioner indoor unit 100 is located at the foot of the bed, the first air guide plate 120 and the second air guide plate 140 can also be controlled to send air downward and front and lower. When the sensor detects that the air conditioner indoor unit 100 is located at a side of the bed 200, the first air guide plate 120 can also be controlled to send air horizontally forward and forward upward, and the second air guide plate 140 can be controlled to send air downward and front and lower. Users can set it according to personal needs, and both avoid direct wind blowing on the bed 200.
