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 products such as air-conditioning hoods, which add air-conditioning components to the range hood platform, and can realize all the functions of the range hood and the functions of the air conditioner at the same time, these air-conditioning hoods often simply merge the functions of the traditional air-conditioning indoor unit and the traditional range hood, and the air-conditioning outdoor unit still needs to be installed separately outdoors. This type of air-conditioning range hood is not integrated enough, and the installation is cumbersome. In addition, the pipes and lines connecting the indoor and outdoor units of the air-conditioning will also damage the wall. Summary of the invention

[0006] The first technical problem to be solved by the present invention is to provide a kitchen air conditioning system with novel structure, compactness and high integration in view of the above-mentioned existing technical status.

[0007] The second technical problem to be solved by the present invention is to provide a kitchen air conditioning system which can save system material cost and space and has good energy-saving effect in view of the above-mentioned existing technical status.

[0008] The technical solution adopted by the present invention to solve the above-mentioned first technical problem 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, the oil fume suction component has a casing, and a smoke exhaust channel is arranged in the casing, which is characterized in that: an air outlet channel is also arranged in the casing, and the air outlet of the air outlet channel is fluidly connected with the kitchen room, the second heat exchanger is arranged in the air outlet channel, and the smoke exhaust channel has at least a vertical smoke exhaust section, and the air outlet channel has at least a vertical air outlet section, and the vertical smoke exhaust section and the vertical air outlet section are distributed left to right or front to back with respect to each other.

[0009] Preferably, an air inlet and an air outlet of the air outlet channel are provided on the housing.

[0010] In order to provide two air intake modes, indoor air intake and outdoor air intake, the air inlet is fluidically connected to the interior of the kitchen or is fluidically connected to the exterior of the kitchen.

[0011] In order to enable the system to discharge air from the top, the air outlet is arranged at the top of the casing and is externally connected to an upper air outlet duct, and the air outlet of the upper air outlet duct is fluidically connected to the kitchen room.

[0012] The technical solution adopted by the present invention for the second technical problem is that, in the kitchen air conditioning system, the first heat exchanger is arranged in the exhaust passage. In this way, when the air conditioner is cooling, the first heat exchanger is used as a condenser, and the oil smoke in the exhaust passage can take away the heat generated by the first heat exchanger. When the air conditioner is heating, the first heat exchanger is used as an evaporator, and the oil smoke in the exhaust passage can take away the cold generated by the first heat exchanger, thereby improving the system performance.

[0013] In order to switch the flue entrance, the smoke exhaust channel includes a first smoke exhaust channel and a second smoke exhaust channel, the fume suction assembly includes a first fan, and a first air duct switching valve for switching one of the first smoke exhaust channel and the second smoke exhaust channel to be connected to the first fan outlet is installed at the rear end of the first fan outlet, and the first heat exchanger is arranged in the first smoke exhaust channel.

[0015] In order to prevent the oil smoke from contaminating the first heat exchanger, an oil smoke purification device is 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.

[0016] In order to enable the air outlet to discharge air smoothly, a second fan for exhausting air is installed in the air outlet channel.

[0017] In order to enable the system to switch between cooling mode and heating mode, a four-way valve is installed on the refrigerant pipeline.

[0018] Compared with the prior art, the advantages of the present invention are: the kitchen air conditioning system is provided with a smoke exhaust channel and an air outlet channel in the casing, the vertical smoke exhaust section and the vertical air outlet section are distributed left and right or front and back with respect to each other, the system structure is more compact and the integration is higher, in addition, after the first heat exchanger is installed in the smoke exhaust channel, when the system is cooling, the fume suction component and the air conditioning component share a fan system, which can save material costs and space; when heating, in addition to sharing the fan, it can also fully absorb the waste heat generated by the stove to achieve energy saving effect.

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.

[0029] The oil fume extraction assembly has a housing 20. The compressor 11 can be arranged adjacent to or inside the housing 20. The compressor can also be installed in other locations in the kitchen, such as the kitchen ceiling. The housing 20 is provided with a smoke exhaust passage 21 and an air outlet passage 22 that are isolated from each other. The smoke exhaust passage 21 has a vertical smoke exhaust section, and the air outlet passage 22 has a vertical air outlet section. Figure 1 The direction indicated by the middle arrow A is rightward, and the air outlet channel 22 is located on the right side of the smoke exhaust channel 21 .

[0030] A first fan 26 for exhausting oil smoke is installed at the lower part of the casing 20 . The first fan 26 is located below the smoke exhaust passage 21 and the air outlet passage 22 . The air outlet of the first fan 26 is fluidically connected to the smoke exhaust passage 21 .

[0031] The smoke exhaust channel 21 specifically includes a first smoke exhaust channel 211 and a second smoke exhaust channel 212. The first smoke exhaust channel 211 and the second smoke exhaust channel 212 are basically arranged horizontally along the shell 20, and the first smoke exhaust channel 211 is located below the second smoke exhaust channel 212. A first air duct switching valve 3 is installed at the entrance of the first smoke exhaust channel 211 and the second smoke exhaust channel 212.

The outlets of the first smoke exhaust channel 211 and the second smoke exhaust channel 212 share the same smoke exhaust pipe 5. A second air duct switching valve 6 is installed at the outlet of the first smoke exhaust channel 211 and the second smoke exhaust channel 212. In this embodiment, the second air duct switching valve 6 is a one-way check valve.

[0032] The first heat exchanger 12 of this embodiment is arranged in the first smoke exhaust channel 211, and a fume purification device 4 is also installed in the first smoke exhaust channel 211. The fume purification device 4 is arranged upstream of the first heat exchanger 12 along the path of the fume flow. The fume purification device 4 can generally adopt various electrostatic purification devices in the prior art to prevent the fume from polluting the first heat exchanger 12. Figure 1 The middle arrow A indicates the right direction, and the oil fume purification device 4 is located on the left side of the first heat exchanger 12 .

[0033] The housing 20 is provided with an air inlet 23 and an air outlet 24 of the air outlet channel 22, and the second heat exchanger 13 and the second fan 27 are installed in the air outlet channel 22. The air inlet 23 can be in fluid communication with the kitchen interior, and can also be in fluid communication with the kitchen exterior. The air outlet 24 is arranged at the top of the housing 20 and is externally connected to an upper air outlet duct 25, and the air outlet of the upper air outlet duct 25 is in fluid communication with the kitchen interior. Usually, the air outlet of the upper air outlet duct 25 can be arranged on the kitchen ceiling, so that cold air or warm air can be sent to the kitchen through the air outlet on the ceiling.
