Embodiments of the present application are further described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, an embodiment of the present application provides an air conditioner 100, which includes a main housing 11 and an air duct assembly 200, wherein the air duct assembly 200 includes an air guiding cover 21, the air guiding cover 21 has an air cavity 211, and the main housing 11 is connected with the air guiding cover 21. The main housing 11 is provided with a vent 111, and the vent 111 communicates with a wind chamber 211 of the wind scooper 21. Cold air or hot air produced by the air conditioner 100 can be discharged from the ventilation opening 111 to the outside of the air conditioner 100 through the air chamber 211.

Referring to fig. 1 and 2, in one embodiment, a plurality of ventilation openings 111 are provided. For example, four ventilation openings 111 are provided, which are a first air inlet 111a, a second air inlet 111b, a first air outlet 111c, and a second air outlet 111d. When the air conditioner 100 is in operation, air outside the air conditioner 100 enters the air conditioner 100 from the second air inlet 111b for heat exchange to form cold air or hot air, and the cold air or hot air is discharged through the first air outlet 111 c. The air conditioner 100 is also capable of allowing air outside the air conditioner 100 to enter the air conditioner 100 from the first air inlet 111a and discharging air sucked in from the first air inlet 111a through the second air outlet 111d. The first air inlet 111a, the second air inlet 111b, the first air outlet 111c, and the second air outlet 111d may be covered with a wind scooper 21.

Referring to fig. 1 and 2, in an embodiment, the duct assembly 200 further includes a duct 22, and the duct 22 is used for guiding the flow direction of the airflow. For example, the air conditioner 100 is applied to cooling of a motor home, the air conditioner 100 is placed in the motor home, cold air is blown out from the first air outlet 111c, the air guide covers 21 are respectively covered at the first air inlet 111a and the second air outlet 111d, the air guide covers 21 are connected with the air pipes 22, the air pipes 22 are respectively communicated with the first air inlet 111a and the second air outlet 111d, one end, away from the air guide covers 21, of the air pipes 22 extends out of the motor home, and hot air generated by the second air outlet 111d is discharged out of the motor home, so that cooling in the motor home is realized.

Referring to fig. 1 and 2, in an embodiment, the air conditioner 100 further includes an apparatus main body (not shown), and the main housing 11 is wrapped around the apparatus main body. The apparatus body may include a fan, an evaporator, a condenser, a compressor, and the like for making the normal temperature wind sucked from the air conditioner 100 into cool wind or hot wind.

Referring to fig. 1, 3 and 4, in an embodiment, the duct assembly 200 further includes an adaptor 300, the adaptor 300 is used for connecting the air guiding cover 21 and the duct 22, the adaptor 300 is connected to an end of the air guiding cover 21 away from the air conditioner 100, the air guiding cover 21 includes a clamping block 212, the clamping block 212 is located on a wall surface of the air guiding cover 21 forming the air cavity 211, and the clamping block 212 can form a clamping engagement with the adaptor 300, so that the air guiding cover 21 is connected to the adaptor 300.

Referring to fig. 2 and 5, in an embodiment, the adaptor 300 includes an adaptor body 31 and a clamping member 32. The adapter body 31 has a first end 311 and a second end 312, which are opposite to each other, the first end 311 is used for being abutted with the air duct 22, the second end 312 is used for being abutted with the air guiding cover 21, and the clamping piece 32 is connected to the second end 312.

For example, in one embodiment, the adapter body 31 is annular, and the end surfaces of the first end 311 and the second end 312 are annular. The adapter body 31 has an air duct 313, and the air duct 313 penetrates through the end face of the second end 312 from the end face of the first end 311. The first end 311 of the adapter body 31 is provided with an internal thread 314, the internal thread 314 is located in the air duct 313, and the air duct 22 is provided with an external thread (not shown) matched with the internal thread 314 of the first end 311, so that one end of the air duct 22 can extend into the air duct 313 from the first end 311 and be in threaded connection with the adapter body 31.

Referring to fig. 4 and 6, in an embodiment, the adapter body 31 has a center line L, the locking member 32 uses the center line L of the rotating body as a rotation axis, and the locking member 32 is configured to be able to be locked with the locking block 212 of the wind scooper 21 when rotating along the first direction a, and able to be separated from the locking block 212 of the wind scooper 21 when rotating along the second direction B opposite to the first direction a. By rotating the adapter body 31, the clamping member 32 can be clamped or separated from the clamping block 212 in a rotating manner, and the number of rotation turns is reduced relative to a threaded connection manner, so that the assembly and disassembly efficiency of the adapter member 300 and the wind scooper 21 is improved.

In practical application, after the air duct 22 and the adapting body 31 are connected in advance, the adapting piece 300 is installed on the air guiding cover 21, compared with the air duct 22 which is directly connected with the air guiding cover 21 through threads, the air duct 22 is required to rotate for more than 2 to 3 circles in the installation process, and the convenience of installing and detaching the air duct 22 is improved in a very inconvenient operation mode.

Referring to fig. 5, 6 and 7, in an embodiment, the clamping member 32 includes a first connecting portion 321, a second connecting portion 322 and a third connecting portion 323 sequentially connected. The first connecting portion 321 is connected to the second end 312, a spacing space 33 is formed between the second connecting portion 322 and the second end 312, an inlet 34 is formed between the third connecting portion 323 and the second end 312, the inlet 34 is communicated with the spacing space 33, and the inlet 34 is configured to allow the fixture block 212 of the air guiding cover 21 to enter the spacing space 33. After the clamping block 212 of the air guide cover 21 enters the limit space 33 from the inlet 34, the clamping block 212 of the air guide cover 21 and the clamping piece 32 form a clamping state.

In an embodiment, the first connecting portion 321, the second connecting portion 322 and the third connecting portion 323 are integrally formed, and the first connecting portion 321, the second connecting portion 322 and the third connecting portion 323 are made of metal or plastic, so that the clamping member 32 can be deformed integrally. When the third connecting portion 323 receives an external force in a direction away from the second end portion 312, the size of the inlet 34 can be increased so that the latch 212 can be disengaged from the limit space 33. The external force here does not include the force applied by the clamping block 212 of the wind scooper 21 to the clamping piece 32, that is, when the clamping piece 32 is only subjected to the force applied by the clamping block 212, the deformation generated by the clamping piece 32 is insufficient to make the clamping block 212 separate from the limiting space 33. The size of the inlet 34 refers to the width of the inlet 34, i.e., the minimum distance between the surface of the third connecting portion 323 facing the second end portion 312 and the end surface of the second end portion 312.

In an embodiment, the first connection portion 321 and the second connection portion are disposed in a substantially L shape, and the second connection portion 322 is parallel to an end surface of the second end 312 to form the limiting space 33. Meanwhile, the first connecting portion 321 can play a role in stopping and limiting the clamping block 212.

With continued reference to fig. 5, fig. 6, and fig. 7, in an embodiment, the clip 32 further includes a limiting portion 324, where the limiting portion 324 is protruded on the third connecting portion 323 and exposed in the limiting space 33, a minimum distance between the second connecting portion 322 and the second end 312 is a first distance P1, a minimum distance between the limiting portion 324 and the second end 312 is a second distance P2, and the second distance P2 is smaller than the first distance P1, so as to limit the clip 212 from being separated from the limiting space 33. The limiting portion 324 can limit the clamping block 212 from separating from the limiting space 33, so that when the wind scooper 21 is impacted or vibrated, the wind scooper 21 is not easy to separate from the adaptor 300, and the wind scooper 21 and the air pipe 22 are firmly connected and not easy to detach.

When the adaptor 300 and the wind scooper 21 need to be detached, an external force in a direction away from the second end 312 is applied to the third connecting portion 323, so that the third connecting portion 323 drives the limiting portion 324 to be away from the clamping block 212 until the stopping effect of the limiting portion 324 on the clamping block 212 is released, and the adaptor 300 is rotated along the second direction B, so that the clamping block 212 is separated from the limiting space 33, and the adaptor 300 and the wind scooper 21 are detached, so that the wind pipe 22 and the wind scooper 21 are detached.

Referring to fig. 6 and fig. 7, in an embodiment, the limiting portion 324 has a first surface 3241, the first surface 3241 is disposed opposite to the first connecting portion 321, and an included angle e is formed between the first surface 3241 and the end surface of the second end 312, wherein the included angle e ranges from 70 degrees to 120 degrees.

When the clamping block 212 of the air guiding cover 21 is located in the limiting space 33 and moves towards the inlet 34, the clamping block 212 can move to a position where the limiting space 33 is far away from the first connecting portion 321 and abuts against the first surface 3241. Because the first surface 3241 of the limiting portion 324 forms an angle e of 90 degrees with the end surface of the second end 312, and the second distance P2 is smaller than the first distance P1, the latch 212 cannot enter the position between the limiting portion 324 and the second end 312 along the first surface 3241 from the limiting space 33, and the latch 212 is further limited from being separated from the limiting space 33 from the inlet 34.

For example, the angle e is 90 degrees, at which time the first surface 3241 is perpendicular to the end face of the second end 312. Further, the limiting effect of the limiting portion 324 on the clamping block 212 is improved, and the situation that the clamping block 212 is separated from the limiting space 33 is avoided.

In other embodiments, the included angle e between the first surface 3241 and the end surface of the second end 312 may be 80 degrees, 95 degrees, 100 degrees, or 110 degrees, so that the latch 212 can abut against the first surface 3241, so that the limiting portion 324 can limit the latch 212 from being separated from the limiting space 33.

Referring to fig. 6 and fig. 7, in an embodiment, the limiting portion 324 further has a second surface 3242, the second surface 3242 is disposed opposite to the second end portion 312 and is connected to the first surface 3241 and the third connecting portion 323, a minimum distance between the second surface 3242 and an end surface of the second end portion 312 is a second distance P2, a minimum distance between the third connecting portion 323 and the second end portion 312 is a third distance P3, and the second distance P2 is greater than the third distance P3.

The second distance P2 is set to be greater than the third distance P3 such that a size of the inlet 34 formed between the third connecting portion 323 and the second end portion 312 is smaller than a size of a space between the second surface 3242 and the second end portion 312. On the one hand, when the clamping block 212 and the adapter 300 are subjected to external force, the adapter 300 rotates relative to the wind scooper 21 in the second direction B, so that the clamping block 212 moves in the direction of separating from the limiting space 33 and moves between the second surface 3242 and the end face of the second end 312, the third limiting portion 324 and the second end 312 can block the clamping block 212 from moving in the direction of separating from the limiting space 33, so that the clamping block 212 and the adapter 300 are firmly connected and are not easy to separate. The external force refers only to a force that can rotate the adapter 300 and the latch 212 relative to each other. On the other hand, when the latch 212 of the wind scooper 21 moves from the inlet 34 toward the direction of entering the limit space 33, that is, the adapter 300 rotates in the first direction a relative to the wind scooper 21, the latch 212 can support the third connecting portion 323 and the second end 312, and the third connecting portion 323 and the second end 312 are separated from each other, that is, the third distance P3 becomes larger. Since the limiting portion 324 is connected to the third connecting portion 323, the second surface 3242 is further away from the end surface of the second end portion 312, i.e. the second distance P2 is also greater, and the second distance P2 is greater than the third distance P3, so that the latch 212 is not easy to be blocked by the limiting portion 324 after passing through the inlet 34, and is easier to move toward the limiting space 33.

Referring to fig. 6 and 7, in an embodiment, the third connecting portion 323 includes a first guiding surface 3231. The first guide surface 3231 is located at a side of the third connecting portion 323 toward the second end portion 312, and a distance between the first guide surface 3231 and the second end portion 312 gradually increases in a direction away from the limiting portion 324. When the wind scooper 21 is connected to the adaptor 300, the clip 212 moves along the first guide surface 3231 in a direction approaching the stopper 324 from a position of the first guide surface 3231 away from the stopper 324. The distance between the position of the first guide surface 3231 away from the limiting portion 324 and the second end portion 312 is greater than the distance between the position of the first guide surface 3231 near the limiting portion 324 and the second end portion 312, which makes it easier for the latch 212 to enter the inlet 34 between the third connecting portion 323 and the second end portion 312.

In an embodiment, the stop surface 2121 is a surface of the clamping block 212 facing away from the first connecting portion 321, and the stop surface 2121 is perpendicular to the end surface of the second end portion 312, so that the contact area with the limiting portion 324 can be increased, and the limiting portion 324 has a better stopping effect on the clamping block 212.

Referring to fig. 6 and 7, in an embodiment, the latch 212 is provided with a second guiding surface 2122, and the second guiding surface 2122 is configured to guide the latch 212 to enter the limiting space 33 from the inlet 34, and when the latch 32 rotates in the first direction a, the second guiding surface 2122 contacts a surface of the latch 32 facing the second end 312. The inclination direction of the second guide surface 2122 is the same as that of the first guide surface 3231, when the fixture block 212 enters between the third connecting portion 323 and the second end portion 312, the first guide surface 3231 and the second guide surface 2122 are in contact, and the first guide surface 3231 and the second guide surface 2122 together play a guiding role on the fixture block 212 entering the inlet 34, so that the fixture block 212 is easier to enter the inlet 34, the smoothness of the engagement between the adapter 300 and the fixture block 212 is improved, and the assembly efficiency of the adapter 300 and the air guide cover 21 is further improved.

In an embodiment, a plurality of clamping blocks 212 are disposed on the wind scooper 21, and correspondingly, a plurality of clamping members 32 are disposed on the adapter 300, and the plurality of clamping blocks 212 are in one-to-one correspondence with the plurality of clamping members 32. When the adaptor 300 rotates along the first direction a, the plurality of clamping pieces 32 can simultaneously form clamping with the plurality of clamping blocks 212, so that the adaptor 300 and the wind scooper 21 are firmly connected and are not easy to detach.

In summary, in the air conditioner 100 provided in the embodiment of the utility model, when the air duct 22 needs to be connected to the air guiding cover 21, one end of the air duct 22 extends into the air duct 313 from the first end 311 of the adapting body 31 and is in threaded connection with the adapting body 31 until the air duct 22 abuts against the first wall 361 of the stop ring 36. The second wall 362 of the stop ring 36 abuts against the wind scooper 21, and aligns the inlet 34 of the clamping piece 32 with the clamping block 212 of the wind scooper 21, and rotates the adapter piece 300 along the first direction a, so that the clamping block 212 enters the limiting space 33, the clamping piece 32 and the clamping block 212 are clamped, the adapter piece 300 is connected with the wind scooper 21, and then the connection between the air pipe 22 and the wind scooper 21 is realized. When the air duct 22 is detached, an external force in a direction away from the second end 312 is applied to the third connecting portion 323, so that the stopping effect of the limiting portion 324 on the clamping block 212 is released, the adaptor 300 is rotated along the second direction B, the clamping block 212 is separated from the limiting space 33, the adaptor 300 and the air guide cover 21 are detached, and the air duct 22 and the air guide cover 21 are detached. When the adaptor 300 is separated from the wind scooper 21, an external force in a direction away from the second end 312 needs to be applied to the third connecting portion 323, so that the stopper 324 releases the stopper from the stopper 212, and then the stopper 212 can be separated from the stopper space 33 by the rotation of the adaptor 300. Therefore, the fixing portion 324 improves the connection firmness of the adaptor 300 and the air guiding cover 21, so that the air guiding cover 21 and the air duct 22 are not easy to detach.
