[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0045] In the related art, a kitchen air conditioner includes a housing, a fan, an adapter, and a duct arranged in the housing. The fan is located in the housing, and the adapter and the duct are arranged outside the housing. The outlet of the fan can be communicated with the duct through the adapter, so that the airflow in the housing can be discharged through the duct. However, since the duct is usually installed on the top of the housing through the adapter, the adapter is arranged outside the housing, so that the overall height of the kitchen air conditioner is high, and the kitchen air conditioner occupies a large space. Therefore, it is necessary to consider resetting the structure and / or installation position of the adapter to reduce the space occupied by the kitchen air conditioner.

[0046] Therefore, the present application provides a fan outlet adapter structure for a kitchen air conditioner, which includes a housing, a first adapter, and a second adapter. The first adapter is arranged in the housing, and includes a first connecting end and a second connecting end. The first connecting end is used for connecting with the outlet of the fan. The second adapter is arranged in the housing, and the first end of the second adapter is connected with the second connecting end. The second end of the second adapter is located outside the housing. The airflow discharged from the outlet of the fan passes through the first adapter and the second adapter in sequence, and is finally discharged through the duct outside the housing. The whole first adapter and part of the second adapter are located in the housing to reduce the occupation of the space outside the housing, so that the overall height of the kitchen air conditioner can be reduced, and the space occupied by the kitchen air conditioner can be reduced.

[0047] The content of the present application will be described in detail below in combination with the drawings, so that a person skilled in the art can understand the content of the present application more clearly and in detail.

[0048] Please refer to Figures 1-2The embodiment of the present application provides a fan air outlet adapter structure 100 for a kitchen air conditioner 200. The fan air outlet adapter structure 100 comprises a shell 130, a first adapter 110 and a second adapter 120. The shell 130 is configured as an outer shell of the fan air outlet adapter structure 100.

[0049] In some embodiments of the present application, the first adapter 110 is arranged in the shell 130. The first adapter 110 can not occupy the external space of the shell 130, which helps to reduce the overall height of the kitchen air conditioner 200, thereby reducing the space occupied by the kitchen air conditioner 200.

[0050] In some embodiments of the present application, the first adapter 110 has a first connecting end for connecting with the fan and a second connecting end for connecting with the second adapter 120. The first connecting end has a circular cross section, and the second connecting end has a square cross section.

[0051] For example, the first connecting end and the second connecting end can be oppositely arranged, and the first connecting end is located below the second connecting end, so that the air flow entering the first adapter 110 enters through the first connecting end and is discharged through the second connecting end. The first connecting end is used for connecting with the air outlet of the fan 300.

[0052] In some embodiments of the present application, the second adapter 120 is arranged in the shell 130, the first end of the second adapter 120 is connected with the second connecting end, and the second end of the second adapter 120 is located outside the shell 130. The part of the second adapter 120 towards the first adapter 110 is arranged in the shell, so as to reduce the occupation of the external space of the shell, reduce the overall height of the kitchen air conditioner, and further reduce the space occupied by the kitchen air conditioner.

[0053] Please refer to Figures 2-3 In some embodiments of the present application, the first adapter 110 and the second adapter 120 are detachably connected. For example, the second adapter 120 can be sleeved on the first adapter 110, and the second adapter 120 and the first adapter 110 can also be connected by bolts. The first adapter 110 and the second adapter 120 are connected in a detachable manner, which facilitates the installation and disassembly of the fan 300, the first adapter 110 and the second adapter 120.

Specifically, the end of the second communicating part 122 away from the first communicating part 121 is arranged outside the shell 130 and communicated with the pipeline. The end of the second communicating part 122 away from the first communicating part 121 is the top end of the second communicating part 122, and the airflow discharged from the top end of the second communicating part 122 is discharged through the pipeline.

[0058] Referring to Figures 2-3 In some embodiments of the present application, the first communicating part 121 and the second communicating part 122 are coaxially arranged. Specifically, the first communicating part 121 and the second communicating part 122 are both in the shape of a circular tube. The central axis of the first communicating part 121 and the central axis of the second communicating part 122 are coaxially arranged, so that the airflow entering the first communicating part 121 can smoothly enter the second communicating part 122 and be discharged from the top end of the second communicating part 122.

[0059] In some embodiments of the present application, the cross-sectional area of the second communicating part 122 is greater than the cross-sectional area of the first communicating part 121 in a plane perpendicular to the height direction of the shell 130. The second communicating part 122 is arranged above the first communicating part 121, and the lower end surface of the second communicating part 122 can abut against the upper end surface of the shell 130 after the first communicating part 121 is inserted into the communicating port, so as to axially limit the second adapter 120.

The second communication part 122 is fixedly connected with the top plate 131, which can improve the connection stability of the second communication part 122 and the top plate 131 and reduce or avoid the movement of the second communication part 122 relative to the top plate 131.

[0062] In some embodiments of the present application, the second communication part 122 is fixedly connected with the top plate 131 by adhesion. Specifically, an adhesive is arranged between the lower end surface of the second communication part 122 and the upper end surface of the top plate 131 to achieve the fixed connection of the second communication part 122 and the top plate 131. The fixed connection by adhesion does not require complex equipment, and the process is simple and low in cost. The entire adhesive surface bears the load, the stress is uniformly distributed, and the fatigue resistance is good.
