Kitchen air conditioning system

Abstract

A kitchen air conditioning system includes an air conditioning component and a fume extraction component. The air conditioning component includes a compressor, a first heat exchanger and a second heat exchanger. The compressor, the first heat exchanger and the second heat exchanger are connected through a refrigerant pipeline. A four-way valve is installed on the refrigerant pipeline. The system is characterized in that the first heat exchanger is located in the exhaust passage of the fume extraction component and a heating device is also included for heating the first heat exchanger. The advantages of the present invention are that the kitchen air conditioning system installs one of the heat exchangers of the air conditioning component in the exhaust passage of the fume extraction component. Since the kitchen air conditioning is under heat pump working conditions, the heat exchanger in the fume extraction machine is prone to frost when the compressor is started. After the heat exchanger is heated by the heating device, the frosting phenomenon can be eliminated, thereby avoiding the phenomenon of poor exhaust of the fume extraction machine and weakened air conditioning performance.

Description

Technical Field

[0001] The invention relates to a kitchen air conditioning system. Background Art

[0002] The kitchen is the main place for people to cook. The quality of the kitchen air environment directly affects the mood of the cook. Especially in the hot summer, the stuffy environment of the kitchen brings great discomfort to the cook. For this reason, people have invented various kitchen air conditioners to cool the kitchen air. The basic form of the existing kitchen air conditioner is not much different from that of the ordinary air conditioner. Generally, there are two forms. One is the internal and external unit split type, that is, the external unit is located outdoors and the internal unit is located indoors. The internal and external units each have a motor fan. The connection method of the internal and external unit split kitchen air conditioner needs to be connected through a pipeline, and a hole needs to be opened on the wall, which destroys the decoration. An external unit needs to be hung outside, and the structure is not compact enough and the overall appearance is not beautiful. The other is that the internal and external units are integrated structures, which can use a double-axis motor or two motors. The internal and external unit integrated 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 put the hose outside the window, which is inconvenient to use; the window machine needs to open a square hole with a large area on the wall to put the machine in, and can be moved 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. In addition, the existing kitchen air conditioner is not organically combined with the range hood, and the structure is not compact enough. In summary, the existing kitchen air conditioning system needs to be further improved. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a kitchen air conditioning system capable of defrosting a heat exchanger in a range hood in view of the above-mentioned existing technical status.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: the kitchen air conditioning system includes an air conditioning component and an oil fume suction component, the air conditioning component includes a compressor, a first heat exchanger and a second heat exchanger, the compressor, the first heat exchanger and the second heat exchanger are connected through a refrigerant pipeline, and a four-way valve is installed on the refrigerant pipeline. It is characterized in that: the first heat exchanger is located in the exhaust channel of the oil fume suction component, and also includes a heating device for heating the first heat exchanger.

[0005] Preferably, the oil fume suction assembly includes a first fan, the first heat exchanger is located in the exhaust passage at the rear end of the first fan outlet, and an oil fume purification device is installed in the exhaust passage between the first fan outlet and the first heat exchanger.

[0006] In order to purify the fresh air entering the kitchen, the air conditioning component includes a shell, the second heat exchanger is arranged inside the shell, and an air inlet and an air outlet are opened on the shell. The air inlet is connected to the outside, and the air outlet is connected to the kitchen. A fresh air purification device and a second fan are also installed in the shell. The fresh air purification device is close to the air inlet, and the second fan is located in the air duct between the fresh air purification device and the second heat exchanger.

[0007] In order to hide the indoor unit of the air conditioner, the shell is installed above the kitchen ceiling, an air supply port connected to the air outlet is opened on the kitchen ceiling, and the compressor is located outside the shell and installed above the kitchen ceiling.

[0008] The heating device can have various structures. Preferably, the heating device includes a water tank, a water pump, a water inlet pipe, a water outlet pipe, a first hollow heating plate and a second hollow heating plate. The water tank is used to store hot water. One end of the water inlet pipe is connected to the water tank, and the other end of the water inlet pipe is connected to the first hollow heating plate. One end of the water outlet pipe is connected to the water tank, and the other end of the water outlet pipe is connected to the second hollow heating plate. The first hollow heating plate and the second hollow heating plate are respectively located on both sides of the first heat exchanger and are connected to each other.

[0009] As a preferred solution, the heating device is an electric heater installed on the first heat exchanger.

[0012] Further preferably, the first heat exchanger is an evaporator, and the second heat exchanger is a condenser.

[0013] Compared with the prior art, the advantages of the present invention are: the kitchen air conditioning system installs one of the heat exchangers of the air conditioning component in the exhaust channel of the range hood component. Since the kitchen air conditioning is under heat pump working conditions, the heat exchanger in the range hood is prone to frost when the compressor is started. After the heat exchanger is heated by the heating device, the frosting phenomenon can be eliminated, thereby avoiding the phenomenon of poor exhaust of the range hood and weakened air conditioning performance.

[0020] The present invention is further described in detail below with reference to the accompanying drawings.

[0021] Embodiment 1:

[0022] like Figure 1 and Figure 2 As shown, the kitchen air conditioning system of this embodiment includes an air conditioning component 1 and a fume extraction component 2. The air conditioning component 1 includes a compressor 11, a first heat exchanger 12 and a second heat exchanger 13. The compressor 11, the first heat exchanger 12 and the second heat exchanger 13 are connected through a refrigerant pipeline 14. A four-way valve 15 is installed on the refrigerant pipeline 14. By switching the four-way valve 15, the air conditioning working mode is switched. The working principle of the air conditioning component 1 is the same as that of the existing air conditioner, and will not be described in detail here.

[0023] In this embodiment, the oil fume extraction component 2 adopts a range hood, and a first fan 21 is installed inside the range hood. The first heat exchanger 12 is installed in the exhaust channel 22 at the rear end of the first fan outlet, and an oil fume purification device 23 is installed in the exhaust channel between the outlet of the first fan 21 and the first heat exchanger 12, so as to prevent the oil fume from contaminating the first heat exchanger 12.
