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 a relatively novel distribution method of smoke exhaust channels and air outlet ducts 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.

[0010] Preferably, the smoke exhaust channel is annular and surrounds the air outlet channel.

[0011] The technical solution adopted by the present invention to solve the second technical problem is: 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.

[0012] Further preferably, the air inlet is arranged on the left and right sides of the air outlet channel, and the air outlet is arranged on the front side of the air outlet channel.

[0013] In order to enable the air conditioner to achieve top air outlet, the air outlet 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.

[0014] In order to realize the switching of corresponding smoke exhaust channels under different work modes, the smoke exhaust channel includes a first smoke exhaust channel and a second smoke exhaust channel, and the fume suction component includes a first fan. The rear end of the first fan outlet is equipped with a first 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.

[0015] Further preferably, the first smoke exhaust channel and the second smoke exhaust channel are connected to the smoke exhaust pipe, and a second air duct switching valve for switching one of the first smoke exhaust channel and the second smoke exhaust channel to be connected to the smoke exhaust pipe is installed at the outlet of the first smoke exhaust channel and the outlet of the second smoke exhaust channel.

[0016] Further preferably, the second air duct switching valve includes a first check valve installed at the outlet of the first smoke exhaust channel and a second check valve installed at the outlet of the second smoke exhaust channel.

[0017] In order to prevent the oil fume entering the first smoke exhaust channel from contaminating the first heat exchanger, the first heat exchanger is arranged in the first smoke exhaust channel, and an oil fume purification device is also installed in the first smoke exhaust channel, and the oil fume purification device is arranged upstream of the first heat exchanger along the path of the oil fume flow.

[0018] The first fan may have a variety of air intake modes, wherein the first fan is a centrifugal fan and has single-side air intake or double-side air intake.

[0019] In order to enable the air outlet channel to discharge air smoothly, a second fan is installed in the air outlet channel to supply air to the air outlet of the air outlet channel.

[0020] In order to switch the working mode of the air conditioner, a four-way valve is installed on the refrigerant pipeline.

[0027] The present invention is further described in detail below with reference to the accompanying drawings.

[0028] Embodiment 1:

[0029] 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.

[0030] The fume extraction assembly has a housing 20. The compressor 11 can be arranged adjacent to or inside the housing 20. A smoke exhaust passage 21 and an air outlet passage 22 isolated from each other are arranged on the top of the housing 20. The air outlet passage 22 is accommodated in the smoke exhaust passage 21. In this embodiment, the smoke exhaust passage 21 is annular and surrounds the air outlet passage 22. In addition, the smoke exhaust passage 21 and the air outlet passage 22 can be detachably mounted on the top of the housing 20. The air outlet passage 22 has an air inlet 23 and an air outlet 24. The air inlet 23 is arranged on the left and right sides of the air outlet passage 22. The air inlet 23 can be fluidly connected to the outside of the kitchen or to the outside of the kitchen. The air outlet 24 is arranged on the front side of the air outlet passage 22 and is connected to the inside of the kitchen.

[0031] A first fan 26 for exhausting oil smoke is arranged in the housing 20. The first fan 26 of the present embodiment is a centrifugal fan with single-side air intake. The smoke exhaust passage 21 is arranged at the rear end of the air outlet of the first fan 26, that is, the air outlet of the first fan 26 is fluidly connected with the smoke exhaust passage 21. The smoke exhaust passage 21 specifically includes a first smoke exhaust passage 211 and a second smoke exhaust passage 212. A first air duct switching valve 3 is installed at the entrance of the first smoke exhaust passage 211 and the second smoke exhaust passage 212. Through the first air duct switching valve 3, one of the first smoke exhaust passage 211 and the second smoke exhaust passage 212 can be connected to the air outlet of the first fan 26. A second air duct switching valve 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 includes a first check valve 51 installed at the outlet of the first smoke exhaust channel 211 and a second check valve 52 installed at the outlet of the second smoke exhaust channel 212, and the first smoke exhaust channel 211 and the second smoke exhaust channel 212 share the same smoke exhaust pipe 6 for exhausting smoke.

[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. The second heat exchanger 13 is arranged in the air outlet channel 22, and a second fan 27 is also installed in the air outlet channel 22, so that the air outlet 24 can smoothly discharge air and then replenish it into the kitchen.

[0033] The working principle of the kitchen air conditioning system is as follows:

[0034] Taking the cooling mode as an example, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator.

[0035] The range hood and the air conditioner are both turned on, the first air duct switching valve 3 swings to the left, the first check valve 51 opens, and the second check valve 52 closes, that is, the first smoke exhaust channel 211 is opened and the second smoke exhaust channel 212 is closed. At this time, the smoke is discharged through the first smoke exhaust channel 211 and the smoke exhaust pipe 6, and the smoke airflow sweeping 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 12, and further improving the air conditioning energy efficiency. At the same time, under the action of the second fan 27, the cold air is directly sent into the kitchen from the air outlet 24.

[0036] Only the range hood is turned on, the first air duct switching valve 3 swings right, the first check valve 51 is closed, and the second check valve 52 is opened, that is, the second smoke exhaust channel 212 is opened and the first smoke exhaust channel 211 is closed. At this time, the smoke sucked in by the first fan 26 is discharged through the second smoke exhaust channel 212 and the smoke exhaust pipe 6.

[0037] In the heating mode, the air duct switching method is the same as the cooling mode, the difference is that the air outlet 24 blows warm air into the kitchen, and the cold air of the first heat exchanger 12 is discharged with the oil smoke.

[0038] like Figure 3 As shown, the air outlet 24 of this embodiment is externally connected to an upper air outlet duct 25, and the air outlet of the upper air outlet duct 25 is fluidically connected to the kitchen room. Usually, the air outlet of the upper air outlet duct 25 can be set on the kitchen ceiling, so that cold air or warm air can be supplied to the kitchen through the air outlet on the ceiling.

[0039] Embodiment 2:

[0040] like Figure 4 and Figure 5 As shown, the first fan 26 of this embodiment is a double-inlet centrifugal fan, and the remaining structure is the same as that of the first embodiment, which will not be described in detail here.

[0041] 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.
