Description

A kitchen air conditioning system

Technical field

The invention relates to a kitchen air conditioning system.

Background technique

The kitchen is the main place for people to cook, and the quality of the kitchen air environment directly affects the cooking experience. The kitchen is hot in summer and cold in winter, and there is a need for cooling and heating. For this reason, people invented various kitchen air conditioners to cool the kitchen air in summer and provide warm air to the kitchen in winter to improve cooking comfort.

There is no big difference between the basic form of existing kitchen air conditioners and ordinary air conditioners. Generally, there are two forms, one is the split type of internal and external units, that is, the external unit is located outdoors, the internal unit is located indoors, and the internal and external units each have a motor fan. The internal and external unit split-type kitchen air conditioner connection method needs to be connected through pipelines, and holes need to be opened on the wall to destroy the decoration. An external unit needs to be hung outdoors, which is difficult to install and the structure is not compact enough. The other is the integrated structure of the internal and external units. Although it can install the evaporator and condenser of the air conditioner indoors, a larger area of the wall must be destroyed to install the condenser heat pipe, which not only increases the difficulty of installation, but also It also affects the beauty of the interior. The integrated internal and external machine usually includes a mobile air conditioner and a window machine. When the mobile air conditioner is used, it is necessary to manually connect the heat dissipation hose and place the hose outside the window, which is inconvenient to use; the window machine needs to open a square, area on the wall For larger holes, put the machine in and move it out when not in use, leaving a square hole on the wall. Although it can be plugged with other things, it is troublesome and ruining the decoration.

In addition, due to the limited space in the kitchen, the volume of the kitchen air conditioner cannot be too large. Therefore, the heat dissipation of the kitchen air conditioner has a big problem. If the kitchen air conditioner is not used for heat dissipation in time, the energy efficiency of the air conditioner will be greatly reduced. However, the existing kitchen air conditioner and the range hood work independently of each other, and the two cannot be linked. The heat generated by the kitchen air conditioner cannot be discharged to the outside through the fan of the range hood. Therefore, how to exhaust the heat generated by the kitchen air conditioner through the range hood becomes Problems that people need to solve urgently.

Although, there are also products such as air-conditioning hoods, that is, air-conditioning components are added to the range hood platform, which can not only realize all the functions of the range hood, but also realize the function of air conditioning. However, these air-conditioning hoods often combine traditional air-conditioning indoor units and traditional range hoods with simple functions. The air-conditioning outdoor units still need to be installed outdoors separately. The air-conditioning range hoods in this way are not integrated enough, and the installation is more cumbersome. , The pipes and wiring connections of the internal and external units of the air conditioner will also damage the wall.
