Description

kitchen air conditioner

technical field

The utility model relates to the technical field of air conditioners, in particular to a kitchen air conditioner.

Background technique

The current kitchen air conditioners have the following two types of structures: one is to set the evaporator in the kitchen, when the kitchen air conditioner is running, the air in the kitchen will exchange heat through the evaporator to achieve the effect of cooling the room; the other is to install the evaporator , condenser and compressor are all arranged on the outside of the kitchen, and the air outside the kitchen is sent to the kitchen after the cooling of the outside of the kitchen through the pipeline to make the kitchen cool down. In the first structural mode, since the evaporator of the kitchen air conditioner is located inside the kitchen, a large amount of oil fume will adhere to the surface after a period of long-term operation, seriously affecting the heat exchange effect of the evaporator, and greatly reducing the use effect of the air conditioner.
