Description

A kitchen airflow organization system

technical field

Background technique

The kitchen is the main place for people to cook, and the quality of the kitchen air environment directly affects the comfort of cooking. Especially in the hot summer, the high temperature environment in the kitchen will cause physical discomfort to the cooking staff, resulting in suffocation and sweating. If an external electric fan is added, although the discomfort of the cooking staff can be relieved to a certain extent, the electricity The airflow blown by the fan will have a direct impact on the cooking fire, and it will also blow away the fumes and affect the effect of absorbing the fumes.

To this end, people have invented kitchen air conditioners, which can cool the kitchen air in summer and provide warm air to the kitchen in winter to improve cooking comfort. Existing kitchen air conditioners are generally divided into two types: split type and integrated type. The split type kitchen air conditioner includes an inner unit and an outer unit.

Blow out cold or hot air into the kitchen room through the air outlet of the air conditioner. The integrated kitchen air conditioner usually includes a mobile air conditioner and a window unit. When the mobile air conditioner is used, it is necessary to manually connect the cooling hose and put the hose outside the window, which is inconvenient to use; the window unit needs to open a square, For larger holes, put the machine in and take it out when not in use, leaving a square hole on the wall. Although it can be blocked with other things, it is troublesome and destroys the decoration. Although the airflow blown by the existing kitchen air conditioner will not adversely affect the fire and the effect of absorbing oil fume, it only plays the role of adjusting the indoor ambient temperature of the kitchen. Under the action, they are directly inhaled into the flue of the range hood, and there is no airflow organization path in the kitchen that can effectively improve the cooking comfort of the cook, nor can it play the role of reducing the escape of oil fume gas and improving the effect of oil fume absorption. .
