Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1 and 2, the present embodiment provides an air conditioner 1, where the air conditioner 1 includes an air conditioner housing 11 and an air duct assembly 12, the air conditioner housing 11 includes a housing body 111, the air duct assembly 12 is detachably connected to the housing body 111, a mounting opening 1111 is disposed on the housing body 111, and when the air duct assembly 12 works, air generated by the air conditioner housing passes through the mounting opening 1111 to realize an air supply function.

Referring to fig. 1 and fig. 2, in the present embodiment, the air conditioner casing 11 further includes a door 112 and a driving device (not shown in the drawings), the driving device is installed on the casing body 111, the door 112 is slidably connected to the casing body 111 along a circumferential direction of the casing body 111, the door 112 is in transmission connection with the driving device, the driving device can drive the door 112 to slide relative to the casing body 111, and the installation opening 1111 can be opened or closed when the door 112 slides relative to the casing body 111.

That is, in a case where the door 112 opens the mounting port 1111, the wind generated by the wind tunnel assembly 12 may flow out from the mounting port 1111. When the door 112 closes the mounting opening 1111, the air generated by the air duct assembly 12 cannot flow out from the mounting opening 1111, and at this time, the door 112 may protect and prevent dust for the air duct assembly 12 located in the casing body 111.

It should be noted that, in actual use, even if the door 112 opens the mounting opening 1111, at least a portion of the door 112 may cause an obstruction to the air duct assembly 12. Due to the blocking effect of the door 112, the air duct assembly 12 cannot easily pass through the mounting opening 1111, and the air duct assembly 12 cannot be easily detached from the inside of the casing body 111.

For this reason, in the present embodiment, in a state where the mounting port 1111 is opened, the door body 112 is rotatable with respect to the driving device to switch between the first state and the second state.

In the first state, at least a portion of the door 112 shields the air duct assembly 12 located in the housing body 111, and the door 112 may obstruct the air duct assembly 12 from passing through the mounting opening 1111. At this time, the air duct assembly 12 is not easily separated from the inside of the casing body 111, and the door 112 can protect the air duct assembly 12 in a normal working state.

In the second state, the door 112 slides for a preset distance relative to the shell body 111 and then rotates, an avoiding space 113 communicated with the mounting opening 1111 can be formed between the door 112 and the shell body 111, the air duct assembly 12 is not shielded by the door 112, and the air duct assembly 12 can be separated from the shell body 111 through the avoiding space 113 and the mounting opening 1111. That is, in the second state, the air duct assembly 12 can be detached from the inside of the casing body 111, so as to facilitate subsequent cleaning of the air duct assembly 12.

In the present embodiment, the first state and the second state are switched to each other by rotating the door 112 relative to the driving device.

In actual use, the driving device firstly slides the door body 112 relative to the shell body 111, the mounting opening 1111 is opened, when the door body 112 slides to the limit position, the door body 112 is rotated by external force, and an avoiding space 113 communicated with the mounting opening 1111 is formed between the door body 112 and the shell body 111. Thus, the air duct assembly 12 can be completely exposed in the corresponding region of the mounting opening 1111 and the avoiding space 113, and the air duct assembly 12 can be more easily detached from the housing body 111 through the mounting opening 1111 and the avoiding space 113.

Generally, the angle at which the door body 112 is slidable in the circumferential direction of the case body 111 is 28 °, and the angle at which the door body 112 is rotatable with respect to the drive device is 12 ° in the state in which the mounting port 1111 is opened.

Of course, if the rotatable angle of the door 112 is large, in practical use, the door 112 may also be directly rotated by external force without using a driving device to drive the door 112 first, so that the region where the installation opening 1111 and the avoiding space 113 are communicated can meet the requirement of being capable of passing through the air duct assembly 12.

In the present embodiment, the longitudinal direction of the door body 112 is the same as the vertical direction. Referring to fig. 1 and 2, the door 112 is rotatably connected to the driving device around a predetermined axis 2 extending in a vertical direction. Therefore, on the premise that the door 112 does not shield the air duct assembly 12, the space occupied by the rotation process of the door 112 can be reduced.

Of course, in other embodiments, the door 112 may be rotatably connected to the driving device about an axis extending in the horizontal direction.

It should be noted that the terms "vertical", "horizontal", and the like in this specification indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, or orientations or positional relationships that are conventionally placed when the air conditioner 1 is used. For example, the placement state of the air conditioner 1 in fig. 1 and 2 may be understood as a normal placement state of the air conditioner 1 at the time of normal operation.

Referring to fig. 2 and 3, in the present embodiment, the door body 112 includes a first edge 1121 and a second edge 1122 on two opposite sides of the shell body 111 in the circumferential direction, the first edge 1121 is disposed near the mounting opening 1111, and the second edge 1122 is disposed near the preset axis 2.

Like this, rotating door body 112, in the process of switching to the second state from the first state, the majority of door body 112 can be kept away from shell body 111 gradually, can increase and dodge space 113 for the region that installing port 1111 and dodge space 113 expose is bigger, and wind channel subassembly 12 is more easy through installing port 1111 and dodge space 113.

In the present embodiment, the first edge 1121 and the second edge 1122 both extend in a vertical direction. That is, the first edge 1121, the second edge 1122 and the predetermined axis 2 are parallel to each other.

With reference to fig. 1 and 2, in the present embodiment, the number of the door bodies 112 is two, two door bodies 112 are distributed along the circumferential direction of the case body 111, and the opening width of the two door bodies 112 in the first state is smaller than the opening width in the second state.

Note that, in the present embodiment, the opening width between the two door bodies 112 may be understood as a distance between the first edges 1121 of the two door bodies 112 in the circumferential direction of the case body 111.

It can be understood that, in the process of switching from the first state to the second state, the opening width between the two door bodies 112 is increased, so that the air duct assembly 12 can be conveniently taken out of the casing body 111. In addition, an avoiding space 113 can be formed between the two door bodies 112 and the shell body 111, and the area where the two avoiding spaces 113 are communicated with the mounting opening 1111 is larger, so that the air duct assembly 12 can pass through more conveniently.

It should be noted that in other embodiments, the number of the door bodies 112 may also be one.

Referring to fig. 3 and 4, in the present embodiment, the driving device includes a driving plate 123 and a motor, and the door 112 is rotatably hung on the driving plate 123.

In this embodiment, after the motor is started, the driving plate 123 can be driven to move, the door body 112 follows the driving plate 123, and the door body 112 slides along the circumferential direction of the shell body 111, so as to realize the function of opening or closing the mounting opening 1111.

In the present embodiment, the mutual switching between the first state and the second state can be realized by the rotation process of the door body 112 relative to the transmission plate 123.

It should be noted that the sliding structure between the door 112 and the casing body 111 can be realized by a matching structure between the sliding block and the sliding groove, a matching structure between the pulley and the sliding rail, and the like.

It should be noted that, in this embodiment, an output shaft of the motor is connected to the transmission plate 123 in a transmission manner, the motor can drive the transmission plate 123 to move along the circumferential direction of the shell body 111, and the movement direction of the transmission plate 123 is the same as the movement direction of the door body 112. Therefore, the transmission plate 123 and the door body 112 are not easy to collide or block in the moving process.

Specifically, with reference to fig. 3 and 4, in the present embodiment, the transmission plate 123 is provided with a rack 1231, the rack 1231 extends along the circumferential direction of the housing body 111, and the output shaft of the motor is provided with a gear (not shown in the figure), and the gear is engaged with the rack 1231. That is to say, the motor drives the transmission plate 123 to move along the circumferential direction of the shell body 111 through the rack-and-pinion mechanism, so that the stability of the transmission plate 123 in the moving process can be improved.

Of course, in other embodiments, the motor and the transmission plate 123 may be in transmission connection through a worm and gear mechanism.

It should be noted that, in this embodiment, the door body 112 and the transmission plate 123 are both arc-shaped plates adapted to the shape of the outer wall of the case body 111, so that the probability that the door body 112 and the transmission plate 123 collide with the case body 111 in the moving process can be reduced, and the service lives of the door body 112, the transmission plate 123 and the case body 111 can be prolonged.

Referring to fig. 3 and 5, in the present embodiment, the door body 112 includes an outer door panel 1123 and an inner lining plate 1124, the inner lining plate 1124 is installed inside the outer door panel 1123, and the inner lining plate 1124 is rotatably engaged with the driving plate 123.

Therefore, the inner lining plate 1124 and the transmission plate 123 are in rotating fit with the rotating shaft hole 1125 through the rotating shaft 1232, and the rotating shaft 1232 and the rotating shaft hole 1125 are simple in structure and convenient to process and manufacture.

With reference to fig. 2, it can be understood that, in the present embodiment, the axis of the rotating shaft 1232 coincides with the aforementioned preset axis 2. The rotation shaft hole 1125 is located closer to the second edge 1122 than the first edge 1121, and correspondingly, the rotation shaft 1232 is disposed on the side of the transmission plate 123 far from the mounting opening 1111.

In other embodiments, the driving plate 123 may be provided with a rotating shaft hole 1125, the inner lining plate 1124 is provided with a rotating shaft 1232, and the rotating shaft 1232 is rotatably inserted into the rotating shaft hole 1125, so that the inner lining plate 1124 and the driving plate 123 are rotatably engaged with each other.

Referring to fig. 5, in the present embodiment, a notch 1126 is formed in the peripheral wall of the rotating shaft hole 1125.

It should be noted that the notch 1126 may facilitate the shaft 1232 to be inserted into or removed from the shaft hole 1125, so as to facilitate the assembly or disassembly between the inner lining plate 1124 and the transmission plate 123.

Referring to fig. 4-7, in the present embodiment, the inner lining plate 1124 has a limiting groove 1127, and the transmission plate 123 has a support lug 1233.

It should be noted that, in the process of switching from the second state to the first state, the inner liner plate 1124 and the outer door panel 1123 rotate towards the direction close to the transmission plate 123, the limiting groove 1127 is clamped in the support lug 1233, the support lug 1233 can limit the inner wall of the limiting groove 1127, and the inner wall of the limiting groove 1127 can also limit the support lug 1233. Thus, in the first state, the inner liner plate 1124 is not easily detached from the driving plate 123, and the inner liner plate 1124 and the outer door panel 1123 may follow the driving plate 123, thereby performing a function of opening or closing the mounting port 1111.

Specifically, in this embodiment, the inner wall of the limiting groove 1127 is provided with a limiting portion 1128, after the support lug 1233 is clamped into the limiting groove 1127, the limiting portion 1128 abuts against the support lug 1233, the support lug 1233 can also stop the limiting portion 1128 in the circumferential direction of the shell body 111, and the inner liner plate 1124 and the outer door panel 1123 can move along with the transmission plate 123.
