Description

Kitchen air conditioning system

Technical Field

The invention 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 which are split, 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 split kitchen air conditioner connecting mode of the internal machine and the external machine needs to be connected through a pipeline, holes need to be formed in a wall, decoration is damaged, the external machine needs to be hung outdoors, the mounting difficulty is high, and the structure is not compact enough. The other type is that the interior machine is integral type structure, though it can all install the evaporimeter and the condenser of air conditioner indoor, but need destroy the heat extraction pipe that the wall body of bigger area just can install the condenser, has not only increased the installation degree of difficulty, but also influences indoor pleasing to the eye. 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 the window machine and can be moved out when not in use, a square hole is left on the wall, and the window machine can be plugged by other objects, so that the window machine is troublesome and damages decoration.

In addition, because the kitchen space is limited, the volume of the kitchen air conditioner cannot be too large, so that the heat dissipation of the kitchen air conditioner has a great problem, and if the heat dissipation cannot be carried out in time in the use process of the kitchen air conditioner, the energy efficiency of the air conditioner can be greatly reduced. However, the existing kitchen air conditioner and the range hood work independently, and the kitchen air conditioner and the range hood cannot be linked, and heat generated by the kitchen air conditioner cannot be discharged to the outside through a fan of the range hood, so that how to discharge the heat generated by the kitchen air conditioner through the range hood becomes a problem to be solved urgently.

Although, the existing products such as the air conditioning range hood are also produced, namely, the air conditioning component is added on the basis of the platform of the range hood, all functions of the range hood can be realized, and simultaneously, the function of an air conditioner can also be realized. However, these air conditioning smoke ventilators often carry out simple function with the indoor set of traditional air conditioner and traditional lampblack absorber and merge, and outdoor unit of air conditioner still need install in outdoor alone, and the air conditioning smoke ventilator integrated level of this kind of mode is not enough, and the installation is comparatively loaded down with trivial details, and moreover, the pipeline of air conditioning inside and outside machine and circuit connection also can destroy the wall body. Moreover, the air conditioning component and the oil smoke sucking component of the existing air conditioning range hood are not organically combined, for example, the smoke exhaust channel of the existing air conditioning range hood is not greatly different from the smoke exhaust channel of the existing range hood, and the smoke exhaust channel is not improved due to the combination of the oil smoke sucking component and the air conditioning component.
