[0054] Example 1

[0055] The main body of this embodiment is an air conditioner, including an indoor unit body, wherein the indoor unit body is provided with an air duct structure 100. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the air duct structure 100 includes:

[0056] A fresh air passage 110, wherein the inlet end of the fresh air passage 110 is used to introduce fresh air from the outdoor environment;

[0057] A humidification channel 120, wherein a humidification element is disposed in the humidification channel 120, and an inlet end of the humidification channel 120 is used to introduce air from an external environment;

[0058] An air supply channel 130, wherein the air supply channel 130 is connected to the fresh air channel outlet end 110a and the humidification channel outlet end 120a;

[0059] A switching part, the switching part is used to connect or disconnect the air supply channel 130 and the fresh air channel 110 , and the switching part is also used to connect or disconnect the air supply channel 130 and the humidification channel 120 .

[0060] In this embodiment, the inlet end of the fresh air channel 110 extends to the outdoor environment to receive fresh air from the outdoor environment as fresh air, while the inlet end of the humidification channel 120 is used to receive air from external environments such as indoor environments or outdoor environments for humidification.

[0061] Please combine Figure 4 and Figure 5 , where the direction indicated by the arrow is the direction of fresh air flow. When the user needs fresh air from the outdoor environment, the user can operate the switch to connect the air supply channel 130 with the fresh air channel 110, and then let the fresh air be discharged from the outlet of the air supply channel 130; and when the user needs air conditioning with a certain humidity, please combine Figure 6 and Figure 7 , where the direction indicated by the arrow is the flow direction of the humidified airflow. The user operates the switching part again to connect the humidification channel 120 with the fresh air channel 110, so that the humidification component humidifies the external ambient air passing through the humidification channel 120, and finally discharges the humidified air at the outlet end of the air supply channel 130.

[0062] This embodiment mainly couples the fresh air channel 110, the humidification channel 120 and the air supply channel 130, so that the fresh air channel 110 and the humidification channel 120 share a section of the air duct structure 100, reducing redundant and useless structures, avoiding the bloated structure of the indoor unit body caused by the fresh air channel 110 and the humidification channel 120 being independent of each other, saving precious internal space in the indoor unit body, and further reducing the manufacturing cost of the air conditioner mold.

[0063] More specifically, in the present embodiment, the inlet end of the humidification channel 120 is used to receive the air in the indoor environment, and the inlet end of the humidification channel 120 directly extends to the casing of the indoor unit body to directly receive the air in the indoor environment.

[0064] It should be noted that the fresh air passage 110 is not necessarily limited to extending to the outdoor environment, and the inlet end of the fresh air passage 110 can be connected to the fresh air duct provided inside the indoor unit body. Similarly, the humidification passage 120 is not necessarily limited to having its inlet end exposed on the shell of the indoor unit body, and the inlet end of the humidification passage 120 can be connected to the indoor environment through other passages.

[0065] Please see again Figure 5 and Figure 7 The switching part is used to realize the isolation or connection between the fresh air channel 110 and the humidification channel 120 and the air supply channel 130, and it can be a plurality of components, which respectively control the connection and isolation between the fresh air channel 110 and the air supply channel 130, and the connection and isolation between the humidification channel 120 and the air supply channel 130. For example, in another embodiment, the switching part includes a first switching component and a second switching component, the first switching component is used to control the connection and isolation between the fresh air channel 110 and the air supply channel 130, and the second switching component is used to control the connection and isolation between the humidification channel 120 and the air supply channel 130. For this embodiment, since the first switching component and the second switching component are independent of each other, they need to be configured with independent driving mechanisms, which will occupy valuable space inside the indoor unit body.

[0066] Therefore, in this embodiment, the switching unit includes:

[0067] Active plate 141;

[0068] A driving mechanism, the driving mechanism is connected to the movable plate 141, and is used to drive the movable plate 141 to switch between the first position and the second position;

[0069] The movable plate 141 in the first position blocks the humidification channel outlet end 120a and opens the fresh air channel outlet end 110a, and the movable plate 141 in the second position opens the humidification channel outlet end 120a and blocks the fresh air channel outlet end 110a.

[0070] The switching part provided in this embodiment realizes the on-off control between the fresh air channel 110 and the air supply channel 130 and between the fresh air channel 110 and the humidification channel 120 at the same time through the same movable plate 141, avoiding the separate setting of the first switching component and the second switching component. While effectively improving the compactness of the structure, it also avoids mutual interference between the humidification function and the fresh air function in the air duct structure 100.

[0071] For the above-mentioned driving mechanism, it can adopt a linear driving mechanism or a rotary driving mechanism. For example, in another embodiment, the above-mentioned driving mechanism is a linear driving device, and the telescopic end of the linear driving device is connected to the movable plate 141 so that the movable plate 141 can switch between the first position and the second position.

[0072] Among them, the existing linear drive devices can be divided into two types. One is a component that directly realizes linear movement by itself, such as a linear motor, a cylinder, etc.; the other is a component that converts the rotation of the shaft motor into linear movement through a kinematic pair. For the first type of linear drive device mentioned above, since it requires additional gas circuits, circuits and other systems, the implementation cost is relatively high and its practicality needs to be improved.

[0073] Therefore, in this embodiment, the movable plate 141 is configured to rotate along a rotation axis under the action of the driving mechanism to switch between the first position and the second position. In other words, this embodiment uses a shaft motor 142 as a driving component to drive the movable plate 141 to rotate, thereby reducing the implementation cost of the switching unit.

[0074] Specifically, in another embodiment, the movable plate 141 is connected to the rotating shaft 142a of the rotating shaft motor 142 via a kinematic pair such as a gear pair. Obviously, the connection via a gear pair will increase the difficulty of installing the movable plate 141 and the rotating shaft motor 142. Therefore, in this embodiment, the movable plate 141 is directly fixedly connected to the rotating shaft 142a, so that the movable plate 141 is configured to rotate together with the rotating shaft 142a of the rotating shaft motor 142.

[0075] More specifically, regarding the fixed connection between the movable plate 141 and the rotating shaft 142a, the implementer may set a fixed connection structure on the movable plate 141 and the rotating shaft 142a to achieve fastening between the two. Figure 8 and Fig. 9 In this embodiment, the movable plate 141 includes an integrally formed plate body 141a and a sleeve portion 141b, wherein the sleeve portion 141b extends along the rotation axis and is formed with a shaft hole, and the shaft hole is interference-fitted with the shaft 142a, so that the shaft 142a can drive the movable plate 141 to rotate. Such an arrangement can avoid the need for a kinematic pair and reduce the structural complexity of the switching portion, facilitating large-scale production.

[0076] In addition, in this embodiment, the fresh air channel outlet end 110a and the humidification channel outlet end 120a are arranged side by side, and the rotation axis is parallel to the plane where the fresh air channel outlet end 110a and the humidification channel outlet end 120a are located. In another embodiment, the fresh air channel outlet end 110a and the humidification channel outlet end 120a are arranged side by side, and the rotation axis is perpendicular to the plane where the fresh air channel outlet end 110a and the humidification channel outlet end 120a are located. The implementer can select the specific structure of the fresh air channel 110 and the humidification channel 120.

[0077] At the same time, for the above-mentioned rotation axis, it can be set that the outlet end of the fresh air channel 110a and the outlet end of the humidification channel 120a are facing away from each other on one side, so that the movable plate 141 is driven by the driving motor 142 to switch between the first position and the second position. However, in this way, the structure of the movable plate 141 is relatively complex and easily causes a bloated structure. Correspondingly, in this embodiment, the rotation axis is set between the outlet end 110a of the fresh air channel and the outlet end 120a of the humidification channel to improve the compactness of the structure and reduce the difficulty of forming the movable plate 141.

[0078] Please note that, see Figure 5 and Figure 7 In this embodiment, a certain gap is left between one end of the sleeve portion 141b on one side away from the shaft motor 142 and the rear bracket 224, and the sleeve portion 141b on the other side is directly connected to the edge of the rear bracket 224, that is, only one end of the sleeve portion 141b is matched and connected to the shaft motor 142, and the other end is roughly in a free state. Such a setting can reduce the manufacturing and installation accuracy requirements of the movable plate 141, and facilitate production and installation. The implementer can also establish connections between the two ends of the sleeve portion 141b and the shaft motor 142 and the rear bracket 224 respectively according to their own needs. This disclosure does not specifically limit this.

[0079] For example, in another embodiment, one end of the sleeve portion 141b close to the shaft motor 142 is fixedly connected to the shaft 142a of the shaft motor 142, and one end of the sleeve portion 141b away from the shaft motor 142 is rotationally matched with a positioning hole formed on the rear bracket 224. This arrangement can improve the rotation stability of the sleeve portion 141b and reduce the risk of unexpected situations such as deviation of the movable plate 141 during its own movement.

[0080] The plane where the fresh air channel outlet end 110a is located and the plane where the humidification channel outlet end 120a is located can be parallel to each other but not coplanar, or they can be coplanar with each other. In this embodiment, the plane where the fresh air channel outlet end 110a is located and the plane where the humidification channel outlet end 120a is located are coplanar. This arrangement can reduce the difficulty of structural molding while also reducing the difficulty of designing the movable plate 141 in the switching part, facilitating large-scale production.

[0081] Among them, as for fresh air, since it mainly comes from fresh air in outdoor space, it will carry some dust. Figure 5 and Figure 7 , it is necessary to use a filter to filter the fresh air. In this regard, in the embodiment, a filter 225 is installed on the rear bracket 224. When the fresh air enters the indoor unit body through the fresh air duct, it will first be filtered by the filter 225. The filter 225 is specifically a HEAP filter.

[0082] Obviously, only one filter screen is provided, and the filtering effect on the fresh air is relatively limited. Therefore, a filter element may be provided in the air supply channel 130. To improve the filtering effect, when a filter element is provided in the air supply channel 130, since the air supply channel 130 also passes humidified airflow, the filter element is prone to mildew, which affects the use of the user.

[0083] Therefore, see Figure 4 and Figure 6 In this embodiment, a filter (not shown) is provided in the air supply channel 130, and the filter divides the internal space of the air supply channel 130 into a first chamber 131 and a second chamber 132, and the outlet end of the air supply channel 130 is connected to the second chamber 132;

[0084] Among them, the air supply channel 130 is formed with a first docking port 133 connected to the first chamber 131, and a second docking port 134 connected to the second chamber 132, the first docking port 133 is used to connect with the fresh air channel outlet end 110a, and the second docking port 134 is used to connect with the humidification channel outlet end 120a.

[0085] The first chamber 131 is connected to the second chamber 132 mainly through the filter element. When the indoor unit body is in the fresh air mode, the fresh air passes through the fresh air channel 110, the first chamber 131 and the second chamber 132 in sequence and is blown out at the outlet of the air supply channel 130. At this time, the fresh air is filtered by the filter element. When the indoor unit body is in the humidification mode, the indoor air is blown out at the outlet of the air supply channel 130 only through the humidification channel 120 and the second chamber 132, thereby effectively avoiding the mildew of the filter element caused by the humidified airflow.

[0086] The filter element may be selected to have a style that is consistent with the filter screen 225 installed on the rear bracket 224, or a style that is inconsistent with the style, and the present disclosure does not limit this.

[0087] Furthermore, the indoor unit body provided in this embodiment also includes a fan assembly for cooperating with the air duct structure 100, and the air duct structure 100 described above constitutes a part of the fan assembly. Figure 1 and Figure 2 In this embodiment, the fan assembly includes:

[0088] Wind wheel 211;

[0089] A fan housing, wherein the wind wheel 211 is disposed in the fan housing, and the fan housing has a housing inlet 212a and a housing outlet 212b;

[0090] In the air duct structure 100 described above, the shell inlet 212a is correspondingly connected to the outlet end of the air supply channel 130.

[0091] This embodiment uses a single fan to simultaneously draw outdoor fresh air or air in the indoor environment, avoiding the need to configure independent fans for the humidification module and the fresh air module on the air conditioner, thereby reducing the implementation cost of the indoor unit body and further improving the structural compactness of the indoor unit body.

[0092] In addition, in this embodiment, the humidifying element described above is a wet film 121. When the airflow passes through the wet film 121, the airflow takes away the water molecules on the wet film 121, thereby achieving the purpose of humidifying the air. Implementers can also use components such as nozzles to humidify the air. At the same time, whether the wet film 121 or the nozzle is used as the humidifying element, the air will face greater pressure and flow rate losses when passing through the humidification channel 120. Therefore, in this embodiment, the shell inlet 212a of the fan shell is connected to the outlet end of the air supply channel 130 to increase the pressure and flow rate of the fresh air and humidified airflow entering the indoor environment.

[0093] Furthermore, in order to increase the air output of the fan assembly, in the present embodiment, the number of components of the shell inlet 212a is multiple, the number of components of the air duct structure 100 corresponds to the number of components of the shell inlet 212a, at least two shell inlets 212a are respectively formed on opposite sides of the fan shell in the first direction, at least two groups of air duct structures 100 are symmetrically arranged outside the fan shell on opposite sides in the first direction, and the outlet end of the air supply channel 130 is connected to the shell inlet 212a on the same side.

[0094] The fan assembly provided in this embodiment mainly increases the flow rate of the airflow entering the fan housing by setting a plurality of housing inlets 212a on the fan housing and matching the corresponding air duct structure 100, thereby achieving the output of large air volume and low noise fresh air or humidified airflow, and improving the comfort level of the fresh air or humidified airflow. At the same time, at least two housing inlets 212a and the corresponding air duct structure 100 are symmetrically arranged along the first direction, further improving the compactness of the structure.

[0095] It should be pointed out that the first direction may be a vertical direction or a horizontal direction, and implementers may select the direction according to their own needs. The present disclosure does not specifically limit this. In the present embodiment, the first direction is a horizontal direction.

[0096] The above-mentioned wind wheel 211 can be any one of an axial flow wind wheel housing, a cross-flow wind wheel housing or a centrifugal wind wheel housing. Correspondingly, when the wind wheel 211 is an axial flow wind wheel housing, the fan housing corresponds to an axial flow fan housing. In the present embodiment, the above-mentioned wind wheel 211 is a centrifugal wind wheel housing, and the fan housing corresponds to a volute 212. Specifically, the housing inlet 212a described in the foregoing is respectively formed on both axial ends of the volute 212, so that the volute 212 cooperates with the wind wheel 211 to form a double-suction centrifugal fan capable of achieving large air volume discharge of fresh air and humidified airflow. More specifically, in the present embodiment, the above-mentioned volute 212 is mainly enclosed by a left housing 213 and a right housing 214. The left housing 213 cooperates with the left bracket 135 to enclose the air supply channel 130 located on the left side, and the right housing 214 cooperates with the right bracket 136 to enclose the air supply channel 130 located on the right side.

[0097] See also Figure 2 and Figure 7 In this embodiment, the fan assembly further includes:

[0098] A water tank seat 221 and a water tank 222;

[0099] The water tank 222 is configured to provide humidifying water to the wet membrane 121 , and the wet membrane 121 is mounted on the water tank 222 ;

[0100] The water tank seat 221 is configured to be a container shape with an open end, and the water tank 222 is accommodated in the internal space of the water tank seat 221 through the open end. The water tank seat 221 at least partially defines the humidification channel 120, and the water tank seat 221 and the water tank 222 jointly define an air outlet 223 connected to the inlet end of the humidification channel 120.

[0101] This embodiment mainly improves the shape of the water tank 222 and the water tank seat 221, so that the water tank 222 and the water tank seat 221 together define the air outlet 223 exposed on the exterior of the indoor unit body, avoiding the additional arrangement of the air outlet 223 structure on the indoor unit body, and at the same time achieving the effect of concealing the air outlet 223 and improving the aesthetics of the air outlet 223.

[0102] More specifically, in this embodiment, the water tank seat 221 cooperates with the rear bracket 224 to enclose the fresh air channel 110 distributed on both sides, and the humidification channel 120 is directly enclosed by the water tank seat 221 and the water tank 222. The wet film 121 described above is installed on the wet film 121 installation position formed by the water tank 222 and covers the entrance end of the humidification channel 120. The wet films 121 on both sides are arranged in a left-right symmetrical manner, and the air outlet 223 is formed between the wet films 121 on the left and right sides, facing the front.
