Technical Field

The utility model relates to a kitchen air conditioning system.

Background

The kitchen is the main place that people cook, and the good or bad of kitchen air environment directly influences the culinary art and experiences. The kitchen is hot in summer and cold in winter, and has the requirements of cold supply and heat supply, so that people invent various kitchen air conditioners, the air in the kitchen is cooled in summer, and warm air can be provided for the kitchen in winter, so that the cooking comfort level is improved.

The existing kitchen air conditioner has no big difference from a common air conditioner in basic form, and generally has two forms, namely an internal machine and an external machine split type, namely an external machine is positioned outdoors, an internal machine is positioned indoors, the internal machine and the external machine are respectively provided with a motor fan, the internal machine and the external machine split type kitchen air conditioner are connected in a pipeline mode, holes need to be formed in a wall, decoration is damaged, an external machine needs to be hung outdoors, the installation difficulty is high, and the structure is not compact enough. The other type is that the inside and outside machine is an integrated structure, although the evaporator and the condenser of the air conditioner can be installed indoors, the heat-discharging pipe of the condenser can be installed only by destroying a larger area of wall, so that the installation difficulty is increased, and the indoor attractiveness is influenced. The internal and external integrated machine usually comprises a mobile air conditioner and a window machine, when the mobile air conditioner is used, a heat dissipation hose needs to be manually connected, and the hose is placed outside a window, so that the use is inconvenient; the window machine needs to be provided with a square hole with a large area on the wall, the window machine can be put in and moved out when not in use, and a square hole is left on the wall, so that the window machine can be plugged by other objects, but is troublesome and damages decoration.
