Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner. Background Art

[0002] Existing wall-mounted indoor units use an air guide door to direct the airflow. However, this door typically directs the airflow toward the center of the room, potentially hitting users and resulting in a poor user experience. In particular, the door directs hot air from the indoor unit toward the upper center of the room, minimizing the amount of hot air reaching the lower part of the room. Summary of the Invention

[0003] The problem solved by the present invention is that the air discharged by the existing air conditioner is generally blown directly to the middle of the room, and may be blown directly to the indoor users, and the amount of the blown hot air reaching the lower space of the room is very small.

[0004] In order to solve the above problems, in a first aspect, the present invention provides an air conditioner, comprising:

[0005] The shell is provided with an air outlet;

[0006] The driving member comprises a mounting portion and a driving portion connected to each other, wherein the mounting portion is mounted on the housing;

[0007] The first air guide door is provided with a notch, the driving part extends into the notch and can slide along the notch to avoid interference between the first air guide door and the driving part, and the driving part is used to drive the first air guide door to rotate to open or close the air outlet.

[0008] The air conditioner provided by the present invention has at least the following beneficial effects:

[0009] 1. The first air guide door is connected to the driving portion of the driving member and is driven by the driving portion to rotate. When the first air guide door is rotated to open the air outlet, the air blown out from the air outlet will be guided downward or toward the wall by the first air guide door, so that the blown air will not be blown directly into the middle of the room, reducing the possibility of the air blowing directly toward indoor users;

[0010] 2. When the air conditioner is blowing hot air, the first air guide door can be rotated to a roughly vertical position, so that the hot air can be blown downward or toward the wall, which is conducive to the hot air reaching the lower space of the room. The hot air reaching the lower space of the room will automatically rise under the action of buoyancy, which is conducive to the hot air heating up the entire room;

[0011] 3. The driving portion of the driving member is located in the gap of the first air guide door. When the first air guide door rotates around the driving portion, it is equivalent to the driving portion sliding in the gap, which can avoid interference between the first air guide door and the driving portion. Moreover, the overall assembly of the shell, the driving member and the first air guide door is more compact, reducing the possibility of air leakage.

[0012] In an optional embodiment, the first air guide door includes:

[0013] A hollow shaft, wherein a notch is provided on the outer circumference of the hollow shaft, and the driving part is inserted into the hollow shaft through the notch;

[0014] The air guide body is connected to the hollow shaft.

[0015] In an optional embodiment, the notch extends along the circumferential direction of the hollow shaft, and an extension angle of the notch is greater than or equal to a maximum rotation angle of the first air guide door.

[0016] In this way, when the air conditioner is in any working mode, the first air guide door rotates to a corresponding angle, and the gap has a sufficient length so that the driving part and the first air guide door will not interfere with each other.

[0017] In an optional embodiment, the hollow shaft comprises:

[0018] A first half shaft is connected to the air guide body;

[0019] a second half-shaft detachably connected to the first half-shaft;

[0020] The notches are provided on the outer circumferential surfaces of the first and second semi-axles.

[0021] In this way, the hollow shaft adopts the form of splicing the first half shaft and the second half shaft, which can make the first air guide door convenient to manufacture and easy to assemble.

[0022] In an optional embodiment, the first semi-shaft has a notch extending over a portion of its circumference, and the second semi-shaft has a notch extending over the entire circumference.

[0023] Like this, the method for opening the gap is simple and manufacturing is convenient.

[0024] In an optional embodiment, the first air guide door further includes:

[0025] The latch is installed inside the hollow shaft and is transmission-connected to the driving part.

[0026] In this way, a pin is set inside the hollow shaft to connect with the driving part, so that the driving part, the pin, the hollow shaft and the air guide body are driven in sequence. It not only has a compact structure and occupies less space, but also has high transmission accuracy.

[0027] In an optional embodiment, the air guide body is tangent to the circumference of the first semi-axis.

[0028] In this way, the stress at the connection between the air guide body and the first semi-axle can be reduced, and the connection is firm.

[0029] In an optional embodiment, the air guide body is an arc-shaped structure, and the concave surface of the arc-shaped structure faces the air outlet.

[0030] In this way, the air guide body has less resistance to the air blown out by the air conditioner, the guidance is smoother, and the direction of the wind can be changed more quickly, so that the wind blown out of the air outlet flows downward or toward the wall.

[0031] In an optional embodiment, the driving member includes:

[0032] A support frame, one end of the support frame is connected to the shell, and the other end of the support frame passes through the notch and is inserted into the hollow shaft;

[0033] The rotating member is rotatably arranged in the supporting frame, and the rotating member drives the first air guide door to rotate.

[0034] In this way, the structure of the driving member can be made more compact, and the support frame of the driving member passes through the gap and is inserted into the hollow shaft, which further makes the connection between the driving member and the first air guide door more compact and reduces the possibility of air leakage.

[0035] In an optional embodiment, the air conditioner further comprises:

[0036] The second air guide door has a rotating shaft located at the lower side of the air outlet. When the first air guide door and the second air guide door are both closed, the second air guide door is located at the inner side of the air outlet relative to the first air guide door.

[0037] In this way, under the auxiliary guiding effect of the second air guide door on the wind, the second air guide door and the first air guide door form an air outlet duct with a smaller opening, which can more accurately guide the air outlet to the desired position, especially, can directly guide the hot air to flow downward, and directly guide the cold air to flow horizontally or upward.

DETAILED DESCRIPTION

[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0049] See also Figures 1 to 3 This embodiment provides an air conditioner 100, which includes a housing 110, a driving member (see Figure 8 ), a first air guide door 130 and a second air guide door 140.

[0050] Specifically, the housing 110 has a mounting surface 111 for connecting to a wall surface to securely mount the air conditioner 100 on the wall surface. An air outlet 112 is provided on the housing 110 on the other side of the mounting surface 111 and on the lower surface.

[0051] The driving member includes an interconnected mounting portion (not shown in the figure) and a driving portion 120. The mounting portion is mounted on the housing 110 and located on the upper side of the air outlet 112. That is, the driving member is arranged at the upper edge of the air outlet 112.

[0052] The first air guide door 130 is connected to the driving unit 120, and the driving unit 120 drives the first air guide door 130 to rotate to open or close the air outlet 112. In this way, the rotation centerline of the first air guide door 130 is located above the air outlet 112. When the first air guide door 130 is rotated to open the air outlet 112, the air blown out of the air outlet 112 is guided downward or toward the wall by the first air guide door 130, so that the blown air does not blow directly toward the center of the room, reducing the possibility of the air blowing directly toward indoor users.

[0053] For details, please refer to Figure 3 The first air guide door 130 includes a hollow shaft 131, a latch 135, and an air guide body 136. The latch 135 is installed inside the hollow shaft 131. The driving unit 120 is inserted into the hollow shaft 131 and is in transmission connection with the latch 135. The air guide body 136 is connected to the hollow shaft 131. In this way, the latch 135 is arranged inside the hollow shaft 131 and is in transmission connection with the driving unit 120, so that the driving member, latch 135, hollow shaft 131, and air guide body 136 are driven in sequence. This not only has a compact structure and occupies less space, but also has high transmission accuracy.

[0054] Specifically, the air guide body 136 is tangent to the circumference of the hollow shaft 131. In this way, the stress at the connection between the air guide body 136 and the first semi-shaft 132 is small, and the connection is firm.

[0055] The air guide body 136 is an arc-shaped structure, and the concave surface of the arc-shaped structure faces the air outlet 112. In this way, the air guide body 136 has less resistance to the air blown out of the air conditioner 100, guides it more smoothly, and can change the direction of the air more quickly, so that the air blown out of the air outlet 112 flows downward or toward the wall.

[0056] The rotation axis of the second air guide door 140 is located below the air outlet 112. When both the first air guide door 130 and the second air guide door 140 are closed, the second air guide door 140 is located inside the air outlet 112 relative to the first air guide door 130. Thus, with the auxiliary guidance of the air by the second air guide door 140, the second air guide door 140 and the first air guide door 130 form an air outlet duct with a smaller opening, which can more accurately direct the air to the desired location.

[0057] See also Figure 2 and Figure 3 When the air conditioner 100 blows out hot air, the first air guide door 130 and the second air guide door 140 can be rotated to a roughly vertical state, so that the hot air can be blown downward or toward the wall, which is conducive to the hot air reaching the lower space of the room. The hot air reaching the lower space of the room will automatically rise under the action of buoyancy, which is conducive to the hot air heating up the entire room.

[0058] See also Figure 4 and Figure 5 When the air conditioner 100 blows out cold air, the first air guide door 130 and the second air guide door 140 can be rotated to a roughly horizontal state, so that the cold air can be blown out horizontally or upwardly, which is conducive to the cold air reaching the upper space of the room. The cold air reaching the upper space of the room automatically descends under the action of gravity, which is conducive to the cold air cooling the entire room.

[0059] It is easy to understand that the rotation angles of the first air guide door 130 and the second air guide door 140 can be set according to the operating mode of the air conditioner 100 .

[0060] See also Figure 6 and Figure 7 A notch 134 is provided on the outer surface of the hollow shaft 131, and the driving part 120 extends into the notch 134 and can slide along the notch 134. When the first air guide door 130 rotates around the driving part 120, the driving part 120 is located in the notch 134 to avoid interference between the first air guide door 130 and the driving part 120.

[0061] The notch 134 extends along the circumference of the hollow shaft 131, and the extension angle of the notch 134 is greater than or equal to the maximum rotation angle of the first air guide door 130. Thus, in any operating mode of the air conditioner 100, when the first air guide door 130 rotates to the corresponding angle, the notch 134 is long enough to prevent interference between the driving unit 120 and the first air guide door 130.

[0062] See also Figure 8 The hollow shaft 131 includes a first half-shaft 132 and a second half-shaft 133. The first half-shaft 132 is connected to the air guide body 136 and is integrally formed with the air guide body 136. The second half-shaft 133 is detachably connected to the first half-shaft 132. Thus, the hollow shaft 131 is formed by splicing the first half-shaft 132 and the second half-shaft 133. The first half-shaft 132 and the air guide body 136 are integrally formed, which makes the first air guide door 130 easy to manufacture and assemble.

[0063] The air guide body 136 is tangent to the circumference of the first semi-shaft 132. In this way, the stress at the connection between the air guide body 136 and the first semi-shaft 132 is small and the connection is firm.

[0064] A notch 134 extends partially around the circumference of the first semi-shaft 132, while a notch 134 extends entirely around the circumference of the second semi-shaft 133. This simplifies the design of the notch 134 and facilitates manufacturing. In other words, the notch 134 divides the second semi-shaft 133 into multiple independent cover plates. In this embodiment, three latches 135 are spaced apart within the hollow shaft 131, located at each end and in the middle.

[0065] Correspondingly, the housing 110 is provided with two driving members, which are located at both ends of the housing 110 and correspond to the latches 135 at both ends of the hollow shaft 131. In addition, a reinforcement member 150 is provided in the middle of the housing 110. The reinforcement member 150 has a through hole, the center line of which is collinear with the center line of the driving parts 120 on the two driving members. The through hole in the reinforcement member 150 cooperates with the latch 135 located in the middle of the hollow shaft 131. In this way, when the driving parts 120 at both ends drive the latches 135 at both ends to rotate, the middle latch 135 rotates in the through hole of the reinforcement member 150, so that the reinforcement member 150 supports the hollow shaft 131 and prevents the hollow shaft 131 from deforming.

[0066] Correspondingly, a notch 134 is also provided at the position of the hollow shaft 131 corresponding to the reinforcement 150. When the first air guide door 130 rotates around the driving part 120, the reinforcement 150 is located in the middle notch 134, which is equivalent to the reinforcement 150 sliding in the middle notch 134, thereby avoiding interference between the first air guide door 130 and the reinforcement 150.

[0067] The driving member includes a support frame and a rotating member. One end of the support frame is connected to the housing 110, and the other end of the support frame passes through the notch 134 and is inserted into the hollow shaft 131. The rotating member is rotatably disposed within the support frame, and the rotating member drives the first air guide door 130 to rotate. In this embodiment, the rotating member can be a motor or a gear driven by the motor, or a sleeve driven by the motor or gear, and the sleeve is used to be sleeved on the latch 135. This can further make the structure of the driving member more compact. The support frame of the driving member passes through the notch 134 and is inserted into the hollow shaft 131, further ensuring a tight connection between the driving member and the first air guide door 130 and reducing the possibility of air leakage.

[0068] The air conditioner 100 provided in this embodiment has at least the following beneficial effects:

[0069] 1. The driving member is located above the air outlet 112. The first air guide door 130 is connected to the driving portion 120 of the driving member, and the driving portion 120 drives the first air guide door 130 to rotate. This means that the rotation centerline of the first air guide door 130 is located above the air outlet 112. When the first air guide door 130 is rotated to open the air outlet 112, the air blown out of the air outlet 112 is guided downward or toward the wall by the first air guide door 130, so that the blown air will not be blown directly toward the center of the room, reducing the possibility of the air blowing directly toward indoor users.

[0070] 2. When the air conditioner 100 is blowing hot air, the first air guide door 130 can be rotated to a substantially vertical position, so that the hot air is blown downward or toward the wall, which helps the hot air reach the lower space of the room. The hot air that reaches the lower space of the room will then automatically rise due to buoyancy, which helps the hot air heat the entire room.

[0071] 3. The driving unit 120 of the driving member is located within the notch 134 of the first air guide door 130. As the first air guide door 130 rotates around the driving unit 120, the driving unit 120 slides within the notch 134, thereby preventing interference between the first air guide door 130 and the driving unit 120.

[0072] 4. The air guide body 136 is connected to the driving part 120 of the shell 110 through the hollow shaft 131. Moreover, the driving part 120 is inserted into the interior of the hollow shaft 131, so that the gap between the shell 110 and the hollow shaft 131 can be smaller, and the space occupied by the first air guide door 130 is smaller, which makes the overall assembly of the shell 110, the driving part and the first air guide door 130 more compact and reduces the possibility of air leakage.

[0073] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
