In addition, in connection with other embodiments of the present invention, the tie rod 123 is connected to the tuyere and extends forward.

In addition, a handle 124 perpendicular to the pull rod 123 is arranged at one end of the pull rod 123 adjacent to the air outlet frame 24. In combination with other embodiments of the present invention, an end of the pull rod 123 adjacent to the air-out frame 24 is an end of the pull rod 123 away from the door pocket 11.

Optionally, the air duct shell 20 includes: a rear air duct 21 and a front air duct 22. The rear air duct 21 is provided with a fresh air inlet 205 and a circulating air duct 201. The front air duct 22 is disposed at the front side of the rear air duct 21, the front air duct 22 is provided with a fresh air outlet 206 and an air guide opening 207, the fresh air outlet 206 and the fresh air inlet 205 are front-back opposite and jointly form a fresh air duct 202, and the air guide opening 207 and the air outlet end of the circulating air duct 201 are front-back opposite and jointly form an air supply opening 204. Through the combination of the front air duct and the rear air duct 21, the manufacturing difficulty of the air ducts can be reduced, the air duct shell 20 is convenient to form, and the forming efficiency is improved.

Alternatively, the switch device 10 of the present invention may be configured such that at least a portion of the switch device is disposed in the fresh air inlet 205 for opening the fresh air inlet 205, thereby facilitating the installation of the switch device 10. Also, as will be described below, the fresh air inlet 205 has a larger flow area than the fresh air outlet 206, thereby facilitating installation of the switch device 10.

Optionally, the switch device 10 is configured to be adapted to load the fresh air inlet 205 from the front side of the fresh air inlet 205. So that the installation of the switching device 10 can be facilitated.

In connection with the switch device 10 described in the other embodiments of the present invention, the door pocket 11 may be nested in the fresh air inlet 205, and the switch member 12 is adapted to be mounted on the door pocket 11 from front to rear. Thus, the fresh air duct 202 and the air supply opening 204 in the invention are both arranged in a form extending along the front-back direction, so that the fresh air opening can be conveniently formed in the air supply opening 204, and fresh air is driven to be introduced through the wind wheel 23. In addition, the installation of the switch member 12 is facilitated, the switch member 12 can be moved in the front-back direction conveniently, and the opening and closing of the fresh air duct 202 are facilitated.

Optionally, the switch member 12 abuts against the rear side of the front duct 22 in the open position.

A complete circulation duct 201 can be formed by the cover plate 25.

In the foregoing embodiment, the flow area of the fresh air outlet 206 may be set smaller than the flow area of the fresh air inlet 205, so that negative pressure is more easily generated at the fresh air outlet 206, and the airflow is conveniently introduced into the fresh air duct 202 and sent to the room. And the fresh air inlet 205 with larger flow area can provide more fresh air, and the conveying efficiency of the fresh air is improved.

Optionally, the fresh air duct 202 may communicate with the supply air outlet 204. In the operation process, the air current is sent out from supply-air outlet 204, can guide the air current to be sent to indoor through new trend wind channel 202 equally to provide new trend indoor through new trend wind channel 202.

In addition, in order to make things convenient for the new trend to be sent to indoorly through new trend wind channel 202 steadily, can increase the negative pressure that forms in the exit in new trend wind channel 202 among the operation process to introduce indoor with the new trend more conveniently. In the invention, the negative pressure at the outlet of the fresh air duct 202 can be increased in various ways, at least including that the negative pressure is formed by the structure; negative pressure is provided by the turning of the wind wheel 23.

Optionally, the bottom surface of the air supply outlet 204 includes a first step surface 208, a second step surface 209 and a connection surface 2010, the connection surface 2010 is connected between the first step surface 208 and the second step surface 209, the first step surface 208 is higher than the second step surface 209 to form a step, and the outlet of the fresh air duct 202 is disposed on the first step surface 208. Thus, in the operation process (of the air conditioner 1000 or other equipment), an airflow passage from the return air duct to the air supply opening 204 can be formed through the circulating air duct 201, and because the air supply opening 204 is provided with the step structure, the negative pressure formed at the step can be enhanced, so that fresh air can be conveniently introduced into the room from the air duct.

Advantageously, the step may be provided in a form higher than the circulation duct 201.

In addition, in order to further improve the generation of negative pressure, the first step surface 208 is configured into an arc-shaped surface with gradually decreasing depth in the direction away from the second step surface 209, so that the negative pressure effect at the first step surface 208 can be further improved, the suction force to the airflow in the fresh air duct 202 can be effectively enhanced, and the fresh air volume can be increased.

Alternatively, the present invention may also form negative pressure at the outlet of the fresh air duct 202 by changing the structure of the circulating air duct 201. For example, the circulating air duct 201 is configured to incline from the air return opening 203 to the air supply opening 204 in a direction away from the fresh air duct 202, so that during operation, the air flow is conveyed in a direction deviating from the fresh air duct 202 in a process of being conveyed from the air return opening 203 to the air supply opening 204, and thus, negative pressure can be formed on a side deviating from the conveying direction of the air flow, namely, negative pressure is formed at the position of the fresh air duct 202, thereby effectively improving the effect of the negative pressure.

To further enhance the negative pressure generating effect, the rotation direction of the wind wheel 23 may be changed, for example, the wind wheel 23 is configured to rotate in a direction away from the fresh air duct 202 in a direction from the return air opening 203 to the air supply opening 204. Therefore, in the rotation process of the wind wheel 23, the airflow is conveyed from the air return opening 203 to the direction of the air supply opening 204 far away from the fresh air duct 202, so that the negative pressure effect of the position of the fresh air duct 202 can be further improved.

Optionally, in the present invention, the fresh air duct 202 penetrates through the duct shell 20 along the front-back direction, so that fresh air can be smoothly sent into the room from the back to the front through the fresh air duct 202, the running track of the fresh air in the fresh air duct 202 is relatively simple, and energy loss which may be generated when the direction of the duct changes is avoided.

The circulation duct 201 extends in the longitudinal direction (refer to the up-down direction in the drawing), and the air blowing port 204 is closed at the rear side and opened at the front side for blowing air, that is, the air blowing port 204 is configured in the form of forward blowing air. The air blowing port 204 is configured in a shape extending in the lateral direction (refer to the left-right direction in the drawing) so as to form a wide range of air blowing. The fresh air duct 202 is disposed at one end of the air supply opening 204 along the transverse direction, so that negative pressure is conveniently formed at the position where the fresh air duct 202 is located, and the generation effect of the negative pressure is effectively improved.

The transverse, longitudinal and front-to-back directions are perpendicular to each other.

As shown in fig. 20 to 22, according to the switching apparatus 10 of the embodiment of the present invention, the switching apparatus 10 includes: a door pocket 11 and a switch 12.

Wherein the opening and closing member 12 is adapted to be inserted into the door pocket 11 from the front to the rear, that is, the opening and closing member 12 does not have a non-elastic structure to interfere with the door pocket 11 when the opening and closing member 12 is mounted to the door pocket 11 from the front to the rear. Including but not limited to: the switch 12 can be installed on the door pocket 11 from the front side of the door pocket 11, and the switch 12 and the front side of the door pocket 11 are separated in the front-to-rear projection; alternatively, the switch member 12 may be mounted on the door pocket 11 from the front side of the door pocket 11, and the switch member 12 and the front side of the door pocket 11 have the capability of elastic deformation at a place where the projections from front to back coincide, so that the switch member 12 can give way by elastic deformation during the mounting process.
