Kitchen air conditioning system

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, 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 by switching between the two air ducts. 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

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, and the quality of the kitchen air environment directly affects the cooking experience. The kitchen is hot in summer and cold in winter, and there is a need for cooling and heating. For this reason, people have invented various kitchen air conditioners to cool the kitchen air in summer and provide warm air to the kitchen in winter to improve cooking comfort.

[0003] The basic form of the existing kitchen air conditioner is not much different from that of ordinary air conditioners. Generally, there are two forms. One is the split type of internal and external units, 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 kitchen air conditioner with split internal and external units needs to be connected through pipes, and a hole needs to be opened on the wall, which destroys the decoration. An external unit needs to be hung outdoors, which is difficult to install and the structure is not compact enough. The other is an integrated structure of the internal and external units. Although it can install the evaporator and condenser of the air conditioner indoors, it is necessary to destroy a larger area of ​​the wall to install the heat exhaust pipe of the condenser, which not only increases the difficulty of installation, but also affects the beauty of the room. The integrated internal and external units usually include mobile air conditioners and window units. 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 unit 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.

[0004] In addition, due to the limited space in the kitchen, the size of the kitchen air conditioner cannot be too large. Therefore, there is a big problem in the heat dissipation of the kitchen air conditioner. If the heat cannot be dissipated in time during the use of the kitchen air conditioner, the energy efficiency of the air conditioner will be greatly reduced. However, the existing kitchen air conditioner and the range hood work independently of each other and the two cannot be linked. The heat generated by the kitchen air conditioner cannot be discharged to the outside through the fan of the range hood. Therefore, how to discharge the heat generated by the kitchen air conditioner through the range hood has become a problem that people need to solve urgently.

[0005] Although, there are also products such as air-conditioning hoods, which add air-conditioning components on the basis of the range hood platform, which can realize all the functions of the range hood and the functions of the air conditioner at the same time. However, these air-conditioning hoods often simply merge the functions of the indoor unit of the traditional air conditioner with the traditional range hood, and the outdoor unit of the air conditioner still needs to be installed separately outdoors. The integration of this type of air-conditioning range hood is not enough, and the installation is relatively cumbersome. Moreover, the pipe and line connection between the indoor and outdoor units of the air conditioner will also damage the wall. Moreover, the air conditioning component and the range hood component of the existing air-conditioning hood are not organically combined. For example, its exhaust channel is not much different from the exhaust channel of the existing range hood, and the exhaust channel has not been improved due to the combination of the range hood component and the air conditioning component. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a kitchen air conditioning system with a novel smoke exhaust channel structure, convenient switching and good energy-saving effect in view of the above-mentioned existing technical status.

In this way, the linkage switching of the first air duct switching valve and the second air duct switching valve can be achieved by swinging the swing arm back and forth.

[0010] In order to prevent the oil smoke from contaminating the first heat exchanger, the first heat exchanger is arranged in the first smoke exhaust channel, and an oil smoke purification device is also installed in the first smoke exhaust channel, and the oil smoke purification device is arranged upstream of the first heat exchanger along the path of the oil smoke flow. In this way, the oil smoke is purified by the oil smoke purification device before passing through the first heat exchanger.

When cooling, a fan system is shared to save material cost and space; when heating, in addition to sharing the fan, the waste heat generated by the stove can be fully absorbed to achieve energy saving effect.

[0024] The present invention is further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, the kitchen air conditioning system of this embodiment includes an air conditioning component and a fume extraction component. The air conditioning component 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. The two ends of the four-way valve 15 are connected to the compressor 11, and the other two ends of the four-way valve 15 are respectively connected to the first heat exchanger 12 and the second heat exchanger 13. A throttling component 16 is installed on the refrigerant pipeline 14 between the first heat exchanger 12 and the second heat exchanger 13. A refrigerant flows through the cold channel 4. Common refrigerants can be water, ethylene glycol or propylene glycol, etc. By switching the four-way valve 15, the system can switch between cooling mode and heating mode. In cooling mode, the first heat exchanger 12 is a condenser and the second heat exchanger 13 is an evaporator. In heating mode, the first heat exchanger 12 is an evaporator and the second heat exchanger 13 is a condenser. The specific working principle of the air conditioning assembly 1 is the same as that of the existing air conditioner, and will not be described in detail here.

[0026] The oil fume suction assembly has a casing 20 , a compressor 11 is disposed in the casing 20 or adjacent to the casing 20 , a first fan 25 is disposed in the casing 20 , and a smoke exhaust passage 21 is disposed downstream of the first fan 25 along the path of oil fume flow.

[0027] The smoke exhaust channel 21 of this embodiment includes a first smoke exhaust channel 211 and a second smoke exhaust channel 212. The first fan 25 of this embodiment adopts a horizontally arranged centrifugal fan, and the so-called horizontal arrangement means that the motor shaft of the fan is arranged vertically. In this embodiment, the first smoke exhaust channel 211 and the second smoke exhaust channel 212 are generally arranged horizontally, and the first smoke exhaust channel 211 is located below the second smoke exhaust channel 212, and the first fan 25 is located below the first smoke exhaust channel 211. The entrances of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 are arranged adjacent to each other and a first air duct switching valve 3 is arranged there, so that the two entrances are opened selectively. The first smoke exhaust channel 211 and the second smoke exhaust channel 212 share a smoke exhaust pipe 6 to exhaust oil smoke outward, and the outlet of the first smoke exhaust channel 211 and the outlet of the second smoke exhaust channel 212 are arranged adjacent to each other and a second air duct switching valve 4 is arranged there, so that the two outlets are opened selectively.

[0028] The first air duct switching valve 3 and the second air duct switching valve 4 are configured to be linked in a mechanical linkage manner and / or an electric control linkage manner, that is, both simultaneously open the inlet and outlet corresponding to the same channel in the first smoke exhaust channel 211 and the second smoke exhaust channel 212. In this embodiment, the first air duct switching valve 3 and the second air duct switching valve 4 are both valve plates, and a drive seat 51, a swing arm 52, a first connecting rod 53 and a second connecting rod 54 are installed in the housing 20. The swing arm 52 is installed on the drive seat 51, and the first end of the first connecting rod 53 and the first end of the second connecting rod 54 are both rotatably connected to the swing arm 52, and the second end of the first connecting rod 53 is rotatably connected to the first air duct switching valve 3, and the second end of the second connecting rod 54 is rotatably connected to the second air duct switching valve 4.

[0029] In this embodiment, the first heat exchanger 12 is disposed in the first smoke exhaust channel 211, and a fume purification device 7 is also installed in the first smoke exhaust channel 211. The fume purification device 7 is located at the front end of the first heat exchanger 12, that is, along the path of the fume flow, and the fume purification device 7 is disposed upstream of the first heat exchanger 12. The fume purification device 7 can generally adopt various electrostatic purification devices in the prior art.

[0030] The housing 20 of this embodiment is also provided with an air outlet channel 22, which is isolated from the smoke exhaust channel 21. The air outlet channel 22 of this embodiment is provided at the top of the housing 20, and the air outlet channel 22 has at least a lateral air outlet section. Since the smoke exhaust channel 21 also has a lateral smoke exhaust section, combined with Figure 1 and Figure 3 It can be seen that the transverse air outlet section is located above the transverse smoke exhaust section.

[0031] The air inlet 23 and the air outlet 24 of the air outlet channel 22 are both arranged on the housing 20, and the second fan 26 and the second heat exchanger 13 are installed in the air outlet channel 22. The air inlet 23 can be in fluid communication with the outside of the kitchen or with the outside of the kitchen, and the air outlet 24 is in fluid communication with the inside of the kitchen. In this embodiment, the air outlet 24 is arranged on the top of the housing 20 and is externally connected to an upper air outlet duct 27, and the air outlet of the upper air outlet duct 27 is in communication with the inside of the kitchen, that is, air is finally supplied from the air outlet of the upper air outlet duct 27 to the inside of the kitchen. In addition, the air outlet 24 of the air outlet channel 22 can also be directly in communication with the inside of the kitchen, and the air outlet 22 is preferably arranged on the front of the housing 20.

[0032] The working principle of the kitchen air conditioning system is as follows:

[0033] Taking the cooling mode as an example, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator.

[0034] When both the range hood and air conditioner are turned on, Figure 1 and Figure 2 As shown, through the linkage of the first air duct switching valve 3 and the second air duct switching valve 4, the first smoke exhaust channel 211 is connected between the air outlet of the first fan 25 and the smoke exhaust pipe 6, and the second smoke exhaust channel 212 is closed. At this time, the oil smoke is discharged into the smoke exhaust pipe 6 through the first smoke exhaust channel 211, and the oil smoke airflow passing over the surface of the first heat exchanger 12 can cool and dissipate the heat of the first heat exchanger 12, thereby reducing the temperature of the coolant flowing through the first heat exchanger 12, thereby improving the heat exchange effect of the first heat exchanger, and then improving the air conditioning energy efficiency. At the same time, under the action of the second fan 26, the cold air comes out of the air outlet 24 and enters the upper air outlet duct 27, and is transported to the kitchen room.

[0035] When the range hood is turned on only, Figure 3 and Figure 4 As shown, the second smoke exhaust channel 212 is connected between the air outlet of the first fan 25 and the smoke exhaust pipe 6 through the linkage of the first air duct switching valve 3 and the second air duct switching valve 4, and the first smoke exhaust channel 211 is closed. At this time, the oil smoke sucked by the first fan 25 is discharged into the smoke exhaust pipe through the second smoke exhaust channel 212.

[0036] In the heating mode, the air duct switching method is the same as the cooling mode, the difference is that the upper air outlet duct 27 sends warm air to the kitchen, and the cold energy of the first heat exchanger 12 is discharged into the exhaust pipe 6 along with the oil smoke.

[0037] The "fluid connection" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part respectively), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
