Abstract

A kitchen air conditioning system includes an air conditioning component and an oil fume extraction component. The air conditioning component includes a compressor, a first heat exchanger and a second heat exchanger. The compressor and the oil fume extraction component are provided with exhaust channels in their casings. The exhaust channels include a first exhaust channel and a second exhaust channel that use the same exhaust pipe to exhaust oil fume. The entrances of the two channels are arranged adjacent to each other and a first air duct switching valve is arranged there, so that the two entrances can be opened selectively. The exits of the two channels are arranged adjacent to each other and a second air duct switching valve is arranged there, so that the two exits can be opened selectively. The first heat exchanger is arranged in one of the first exhaust channel and the second exhaust channel. When the kitchen air conditioning system is working, by switching between the two air ducts, the oil fume at the flue outlet can be prevented from flowing back into the flue where the first heat exchanger is located in the oil fume extraction mode. The oil fume in the oil fume extraction + air conditioning mode can take away the heat of the first heat exchanger, thereby improving the heat exchange effect.

Description

Kitchen air conditioning system

Technical Field

The present invention relates to a kitchen air conditioning system.

Background

The kitchen is the main place that people cook, and the cooking experience is directly influenced by the kitchen air environment. The kitchen is hot in summer and cold in winter, and has the demand of cooling and heating, therefore, people invent various kitchen air conditioners, cool the kitchen air in summer, and provide warm air for the kitchen in winter to improve cooking comfort.

The existing kitchen air conditioner has no great difference from the common air conditioner in basic form, and generally has two forms, namely an inner machine and an outer machine which are separated, namely the outer machine is positioned outdoors, the inner machine is positioned indoors, the inner machine and the outer machine are respectively provided with a motor fan, the inner machine and the outer machine are separated, the kitchen air conditioner is connected in a connecting mode through pipelines, holes are formed in a wall, decoration is damaged, an outer machine is hung outdoors, the installation difficulty is high, and the structure is not compact enough. The other is that the inner machine and the outer machine are of an integrated structure, and the evaporator and the condenser of the air conditioner can be installed indoors, but the heat removal pipe of the condenser can be installed only by damaging a wall body with a larger area, so that the installation difficulty is increased, and the indoor attractiveness is also affected. The indoor and outdoor unit generally comprises a mobile air conditioner and a window unit, when the mobile air conditioner is used, a radiating hose is required to be manually connected, the hose is required to be placed outside the window, the window unit is inconvenient to use, a square hole with larger area is required to be formed in the wall, the machine is placed in the window unit, the machine can be moved out when the window unit is not used, and a square hole is left in the wall body, and the window unit can be plugged with other things, but is troublesome and damages the 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 large problem, and if the heat dissipation cannot be timely performed 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 kitchen ventilator work independently, the kitchen air conditioner and the kitchen ventilator cannot be linked, and heat generated by the kitchen air conditioner cannot be discharged outdoors through a fan of the kitchen ventilator, so how to discharge heat generated by the kitchen air conditioner through the kitchen ventilator is a problem to be solved urgently.

Although, at present, products such as an air-conditioning smoke ventilator also exist, namely an air-conditioning component is added on the basis of a smoke ventilator platform, so that not only can all functions of the smoke ventilator be realized, but also the functions of an air conditioner can be realized. However, these air conditioning smoke machines often combine the simple functions of the indoor unit of the traditional air conditioner and the traditional smoke ventilator, and the outdoor unit of the air conditioner needs to be independently installed outdoors, so that the integration level of the air conditioning smoke ventilator is not enough, the installation is complicated, and the pipelines and the circuit connection of the indoor unit and the outdoor unit of the air conditioner can damage the wall. Moreover, the air conditioning component and the oil smoke absorbing component of the existing air conditioning smoke machine are not organically combined, for example, the smoke exhaust channel of the existing air conditioning smoke machine is not greatly different from the smoke exhaust channel of the existing smoke exhaust machine, and the smoke exhaust channel is not improved due to the combination of the oil smoke absorbing component and the air conditioning component.
