Example 1

The main body of this embodiment is an air conditioner, which includes an indoor unit body 100 and an air duct structure disposed in the indoor unit body 100, please refer to fig. 1, in this embodiment, the air duct structure includes:

a volute 310;

an air duct 320, one end of the air duct 320 being communicated with an outlet of the volute 310, an air opening 323 being defined at the other end of the air duct 320, the air opening 323 and the outlet of the volute 310 being arranged in a staggered manner in the axial direction of the volute 310, and the air duct 320 extending in a smooth curve shape along the direction from the outlet of the volute 310 to the air opening 323.

The volute 310 is mainly used for matching with a centrifugal fan blade, drawing an air flow from an inlet of the volute 310, and discharging the air flow at an outlet of the volute 310 at a certain pressure and speed, and the air duct 320 is used for transmitting the air flow blown out from the outlet of the volute 310, so as to realize air supply.

Referring to fig. 1 again, in the present embodiment, the air duct 320 is configured to extend in a smooth curve shape along the direction from the outlet of the spiral casing 310 to the air inlet 323, and when passing through the air duct 320, the air flow can smoothly flow along the inner wall of the air duct 320.

The axial direction of the scroll 310 refers to a direction parallel to a reference center line of a spiral extending section in the profile of the scroll 310, the spiral extending section in the profile of the scroll 310 extends spirally around the reference center line, an outlet of the scroll 310 is formed on a circumferential side wall of the scroll 310, and an inlet of the scroll 310 is formed on an axial end of the scroll 310.

In the present embodiment, please refer to fig. 2, a schematic view of a side of the air duct structure provided in this embodiment, which is opposite to the air opening 323, wherein the air duct 320 includes a first extending section 321 and a second extending section 322 sequentially connected in a direction from the outlet of the volute 310 to the air opening 323;

under the view angle perpendicular to the air opening 323, the line of the first extending section 321 bends at a first included angle α relative to the spiral case 310, and the second extending section 322 bends at a second included angle β relative to the first extending section 321, that is, the whole air duct structure is substantially in an S shape, so that the space utilization efficiency inside the indoor unit body 100 can be improved, and the design difficulty of the whole indoor unit body 100 can be reduced. Meanwhile, in the present embodiment, the first included angle α is configured to be 120 ≦ α ≦ 170 °, and the second included angle β is configured to be α ≦ β ≦ α +50 °. The air outlet path of the volute 310 extends along the direction from the volute 310, the first extending section 321 to the second extending section 322. If the first included angle α between the volute 310 and the first extending section 321 and the second included angle β between the first extending section 321 and the second extending section 322 are too small (for example, the first included angle α and the second included angle β are acute angles), the aerodynamic resistance of the whole air duct structure is significantly improved, and therefore, in this embodiment, by the specific configuration of the first included angle α and the second included angle β, the aerodynamic resistance at the transition position of the volute 310, the first extending section 321, and the second extending section 322 is reduced, so that the air flow can smoothly and smoothly pass through the whole air duct 320, the moving path of the air flow does not excessively turn, and thus, the smooth transition of the air flow is realized. Similarly to the above description, referring to fig. 3, in the present embodiment, the straight line perpendicular to the plane of the tuyere 323 is a first straight line 327, the straight line tangent to the molded end of the volute 310 is a second straight line 328, and the first straight line 327 and the second straight line 328 are arranged at a third angle ψ which is set to 100 ° ψ 160 °. Wherein the gas flow at the tuyere 323 flows substantially in a direction perpendicular to the plane of the tuyere 323, i.e., in a direction parallel to the first line 327. Correspondingly, the flow at the exit of the volute 310 flows generally tangentially to the line end of the volute 310, i.e., parallel to the second line 328. Through the specific arrangement of the third included angle psi, the gentle change of the air flow between the inlet end and the outlet end of the air duct is realized, the sudden change of the moving direction of the air flow in the air duct 320 is avoided, and the resistance of the air duct structure to the air flow is reduced.

Further, for the tuyere 323, it is easy to accumulate fly ash in the indoor environment when the module is idle. In order to prevent the dust from entering the module through the tuyere 323, referring to fig. 4 and 5, in this embodiment, the air duct structure further includes:

a cover plate 324, wherein the cover plate 324 is arranged at the tuyere 323;

the driving mechanism 325 is connected with the cover plate 324 to drive the cover plate 324 to open or close the air port 323;

wherein, a part of the side wall of the tuyere 323 is recessed towards the central portion of the tuyere 323 to define a recessed area 326 at the outer side of the air duct 320, and the driving mechanism 325 is disposed in the recessed area 326.

The cover plate 324 is mainly used for closing the tuyere 323, and the cover plate 324 has a first position for opening the tuyere 323 and a second position for closing the tuyere 323 under the driving of the driving mechanism 325. In order to ensure that the cover plate 324 can completely cover the whole tuyere 323, a cantilever area with a larger area is often formed on the cover plate 324. When the cover plate 324 is pressed, the distance between the joint of the cover plate 324 and the driving mechanism 325 and the pressing force acting line, i.e., the moment arm of the pressing force, is very large, which may cause the joint of the cover plate 324 and the driving mechanism 325 to be easily broken or failed by the pressing force.

Correspondingly, referring to fig. 1 and 5, in the present embodiment, the sidewall of the air inlet 323 at the end of the air duct 320 is recessed inward to define a recessed region 326, and the driving mechanism 325 is disposed in the recessed region 326, so that the joint of the driving mechanism 325 and the cover plate 324 moves a certain distance toward the central portion of the air inlet 323, thereby reducing the force arm at the joint of the cover plate 324 and the driving mechanism 325 when the cover plate 324 is pressed, further improving the reliability of the cover plate 324 and the driving mechanism 325, and improving the durability of the mechanism.

In addition, it should be noted that the portion of the sidewall of the tuyere 323 recessed toward the central portion of the tuyere 323 may be configured as a circular arc shape as shown in the present embodiment to reduce the aerodynamic resistance of the airflow at the position, and may also be configured as a right-angled edge shape, which is not limited by the present disclosure. Further, referring to fig. 5, in the present embodiment, in the plane of the tuyere 323, the projection of the side wall of the end of the air duct 320 to the central portion of the tuyere 323 is in the shape of an arc, the length of the arc is L1, the size of the L1 is configured to be 100 to 160mm, and the width of the projection of the side wall of the whole tuyere 323 is L2, wherein L2 is greater than or equal to 1.2 × L1, so as to ensure that the pneumatic performance of the tuyere 323 is not greatly affected by the portion of the side wall of the tuyere 323 recessed toward the central portion while the recessed region 326 is formed.

In this embodiment, the air duct structure is a part of the fresh air module, and the air port 323 constitutes a fresh air outlet. For fresh air, which is mainly fresh air in the outdoor space, some dust is inevitable, and the fresh air needs to be used with the filter 200. Correspondingly, in this embodiment, the indoor unit further includes a filtering member 200 disposed in the indoor unit body 100, a fresh air channel is defined in the indoor unit body 100, and the filtering member 200 is disposed at an inlet of the scroll casing 310 and between the fresh air channels to filter fresh air. Referring to fig. 10 and 11, in the present embodiment, the fresh air channel is mainly enclosed by the induced draft shell 140.

In this embodiment, the filter 200 is a filter plate. It is understood that the filter element 200 may be a filter screen structure or a filler adsorption structure containing activated carbon filler, which can realize fresh air filtration. In addition, when the filter structure is adopted, the filter 200 may be one or a combination of multiple layers of a non-woven fabric filter, a glass fiber filter, a synthetic fiber filter, a nano silver filter, or a photocatalyst filter. The present disclosure is not particularly limited thereto.

Further, in the related art, the fresh air outlet is generally formed between the side portion, the top portion or the rear portion of the indoor unit body 100, and the user does not have a strong visual sense of the fresh air function of the air conditioner. Referring to fig. 6, in the present embodiment, referring to fig. 6, the air opening 323 is correspondingly disposed at the front center of the indoor unit body 100 to enhance the visual sense of the user for the fresh air function of the air conditioner.

After the air inlet 323 is arranged at the center of the front surface of the indoor unit body 100, the volute 310 can be arranged in a deviated manner, that is, the volute 310 and the air inlet 323 are staggered in the axial direction of the volute 310, so that the volume of the whole air duct structure is saved, and the space utilization efficiency is improved. Referring to fig. 9 and 11, in the present embodiment, since the air opening 323 and the scroll 310 are staggered in the axial direction of the scroll 310, for the scroll 310, an accommodating space is formed on a side facing the air opening 323. This receiving space can be used to receive the filter element 200. Correspondingly, in the present embodiment, the filter element 200 is located outside the side of the volute 310 close to the tuyere 323, so as to improve the compactness.

After the air conditioner is operated for a certain period of time, the lower filter member 200 needs to be replaced to clean the filter member 200. In order to facilitate the replacement of the filter member 200 by the user, referring to fig. 7 and 8, in the present embodiment, the indoor unit body 100 is formed with a mounting opening 110 communicated with the inside thereof, and the filter member 200 passes through the mounting opening 110 to be mounted inside the indoor body. After the air conditioner is operated for a certain period of time, the user can directly take out the filter member 200 through the mounting port 110 to perform cleaning or replacement.

More specifically, in the embodiment, the installation opening 110 is disposed on the front surface of the indoor unit body 100. So set up, the user need not move whole indoor set promptly when dismantling filtering piece 200 to change the orientation of whole indoor set, the user can realize filtering piece 200's replacement comparatively easily. The front surface of the indoor unit body 100 refers to a use surface thereof and a surface facing a user during use. In the present embodiment, the air outlet 323 of the indoor unit main body 100 is also formed on the use surface. Note that the front surface of the indoor unit main body 100 does not necessarily have to be provided with the air blowing port 323, and the front surface is a use surface as long as it is kept facing the user during use.

In this embodiment, to facilitate the filter element 200 to be removed from the indoor unit main body 100, in this embodiment, the air conditioner further includes a bracket portion 120 disposed in the indoor unit main body 100, and the filter element 200 is movably connected to the bracket portion 120, so that the filter element 200 can move relative to the bracket portion 120 and be removed from the mounting opening 110 inside the indoor unit main body 100. The filter 200 is movably mounted on the holder portion 120, and when the filter 200 is replaced, a user only needs to move the filter 200 with respect to the holder portion 120.

More specifically, referring to fig. 10 and 11, in the present embodiment, a mounting sliding groove 121 extending in a direction away from the mounting opening 110 is formed at a position of the bracket portion 120 opposite to the mounting opening 110, and the filter element 200 is slidably mounted in the mounting sliding groove 121 along the extending direction of the mounting sliding groove 121, that is, the filter element 200 is movably mounted by mainly using the mounting sliding groove 121. Other types of bracket portions 120 may also be correspondingly selected by the practitioner. For example, in another embodiment, the holder portion 120 is formed with a clamping structure, which clamps the filter 200 in a clamping state and releases the filter 200 in a releasing state. However, with such a solution, the clamping structure needs to be operated each time the filter element 200 is detached, which is complicated in operation and poor in user experience. For another example, in another embodiment, the holder portion 120 is formed with a rotation structure, and the filter 200 is rotatably connected to the holder portion 120. When it is desired to replace the filter element 200, the user need only rotate the entire filter element 200.

Referring to fig. 6, 7 and 9, in this embodiment, the air conditioner further includes a detachable panel 130, and the detachable panel 130 is detachably connected to the indoor unit body 100 to close the installation opening 110. When replacement of the filter element 200 is required, the user merely needs to remove the entire removal panel 130 to expose the entire mounting opening 110. In addition to effectively preventing the mounting opening 110 from being exposed and improving the aesthetic appearance of the product, the removal panel 130 can also limit the filter element 200 to prevent the filter element 200 from being accidentally separated from the mounting opening 110.

The operator can correspondingly set the connection relationship between the filter member 200 and the detaching panel 130 according to his or her own needs. For example, in another embodiment, the filter element 200 is directly mounted on the detaching panel 130, so that the filter element 200 can be drawn out of the mounting opening 110 together with the detaching panel 130 being detached from the indoor unit main body 100.

In addition, in the present embodiment, the air duct 320 extends to the detachable panel 130, so that the air opening 323 is exposed on the detachable panel 130.
