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 second heat exchanger and the first heat exchanger of the air conditioner indoors, it is necessary to destroy a larger area of ​​the wall to install the heat exhaust pipe of the first heat exchanger, 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. 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.

[0004] Although there are products such as air-conditioning hoods, which add air-conditioning components to 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 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 more cumbersome. Moreover, the pipe and line connection between the indoor and outdoor units of the air conditioner will also damage the wall. In addition, during the use of the air-conditioning hood, the evaporator of the air conditioner will produce condensed water, which is currently discharged to the outside through the water pipe, and the condensed water is not effectively utilized. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a kitchen air conditioning system capable of using condensed water generated by a heat exchanger to clean system components in response to the above-mentioned existing technical status.

[0006] 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 second technical problem is: the first heat exchanger of the kitchen air conditioning system 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.

[0010] In order to prevent the oil smoke from contaminating the first heat exchanger, an electrostatic purification device is installed in the first smoke exhaust channel, and the electrostatic purification device is arranged upstream of the first heat exchanger along the path of the oil smoke flow.

[0011] In order to clean the electrostatic purification device, the cleaning device includes a first water pump and a first cleaning water pipe. The water inlet of the first water pump is connected to the water outlet of the water storage container, the water outlet of the first water pump is connected to the inlet of the first cleaning water pipe, and the water outlet of the first cleaning water pipe faces the electrostatic purification device.

The nozzle is installed at the outlet of the second cleaning water pipe and the spray port is facing the first fan.

[0013] The first smoke exhaust channel and the second smoke exhaust channel may have a variety of positional relationships. Preferably, the first smoke exhaust channel and the second smoke exhaust channel are both vertical channels and are distributed left and right with respect to each other.

[0014] Further preferably, the first smoke exhaust channel and the second smoke exhaust channel have independent smoke exhaust ports or share a common smoke exhaust port.

[0015] Further preferably, the smoke exhaust channel and the air outlet channel are isolated from each other.

[0016] Further preferably, an air inlet and an air outlet of the air outlet channel are opened on the casing.

[0017] In order to provide both indoor and outdoor air intake, preferably, the air inlet is fluidically connected to the interior of the kitchen or to the exterior of the kitchen.

[0018] In order to enable the air conditioner to achieve top air outlet, 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.

In addition, when the system is cooling, the oil 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 effects.

[0025] Embodiment 1:

[0026] like Figure 1 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.

[0027] The oil fume suction component has a housing 20, a compressor 11 is installed in the housing 20, a first fan 26, i.e., an oil fume suction fan, is installed in the housing 20, and a smoke exhaust channel 21 is provided at the rear end of the fan outlet, i.e., the smoke exhaust channel 21 is provided downstream of the first fan 26 along the path of oil fume flow. The smoke exhaust channel 21 of this embodiment includes a first smoke exhaust channel 211 and a second smoke exhaust channel 212, both of which are vertical channels and are distributed left and right. The oil fume suction component includes a first fan 25, and a first air duct switching valve 3 for switching one of the first and second smoke exhaust channels 211 and 212 to be connected to the air outlet of the first fan 25 is installed at the rear end of the air outlet of the first fan 25. The outlets of the first and second smoke exhaust channels 211 and 212 share a smoke exhaust port, and a second air duct switching valve 7 is installed at the outlet. By switching the first air duct switching valve 3 and the second air duct switching valve 7 , the first smoke exhaust channel or the second smoke exhaust channel is opened, so that the first smoke exhaust channel 211 and the second smoke exhaust channel 212 can be selectively opened.

[0028] The first heat exchanger 12 of this embodiment is arranged in the first smoke exhaust channel 211, and an electrostatic purification device 4 is also installed in the first smoke exhaust channel 211. In addition, the electrostatic purification device 4 is arranged upstream of the first heat exchanger 12 along the path of oil smoke flow. The electrostatic purification device 4 can generally adopt various electrostatic purification devices in the prior art to prevent oil smoke from polluting the first heat exchanger 12.

[0029] An air outlet channel 22 is also provided in the housing 20. The air outlet channel 22 is located on the right side of the oil smoke channel 21 and above the first fan 26. The air outlet channel 22 is isolated from the smoke exhaust channel 21. The second heat exchanger 13 and the second fan 27 are installed in the air outlet channel 22. The air inlet 23 and the air outlet 24 of the air outlet channel 22 are both provided on the housing 20. The air inlet 23 can be in fluid communication with the kitchen room or with the outside of the kitchen. The air outlet 24 is in fluid communication with the kitchen room. The air outlet 24 of this embodiment is provided at the top of the housing 20 and is externally connected to an upper air outlet pipe 25. The air outlet of the upper air outlet pipe 25 is in fluid communication with the kitchen room, thereby realizing a top-outlet air outlet mode.

[0030] The working principle of the kitchen air conditioning system is as follows:

[0031] Taking the cooling mode as an example, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator.

[0032] The range hood and the air conditioner are both turned on, and the first smoke exhaust channel 211 is opened and the second smoke exhaust channel 212 is closed by switching the first air duct switching valve 3. At this time, the smoke is discharged through the first smoke exhaust channel 211, 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 energy efficiency of the air conditioner. At the same time, under the action of the second fan 27, the cold air is sent from the upper air outlet 25 of the air outlet 24, and finally sent into the kitchen through the air outlet of the upper air outlet 25.

[0033] Only the range hood is turned on, the second smoke exhaust channel 212 is opened by switching the first air duct switching valve 3, and the first smoke exhaust channel 211 is closed. At this time, the oil smoke sucked by the first fan 26 is discharged through the second smoke exhaust channel 212.

[0034] In the heating mode, the air duct switching method is the same as that in the cooling mode, except that the upper air outlet duct 25 delivers warm air to the kitchen, and the cold air of the first heat exchanger 12 is discharged along with the oil smoke.

[0035] When cooling, the fume extraction component and the air conditioning component share a fan system, saving 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 effects.

[0036] In addition, in the cooling mode, the second heat exchanger 13 as an evaporator will generate condensed water. In order to utilize this part of condensed water, a water storage container 5 and a cleaning device 6 are also provided in the housing 20. The water storage container 5 is used to collect the condensed water generated by the second heat exchanger 13. The cleaning device 6 uses the collected condensed water to clean the electrostatic purification device 4 in the first smoke exhaust channel 211. The cleaning device 6 includes a first water pump 61 and a first cleaning water pipe 62. The water inlet of the first water pump 61 is connected to the water outlet of the water storage container 5, and the water outlet of the first water pump 61 is connected to the inlet of the first cleaning water pipe 62. The water outlet of the first cleaning water pipe 62 faces the electrostatic purification device 4. Under the action of the first water pump 61, the condensed water flows to the electrostatic purification device 4 to clean it.

[0037] Embodiment 2:

[0038] like Figure 2 As shown, the cleaning device 6 of this embodiment is used to clean the first fan 26 of the fume suction assembly. The specific structure is that the cleaning device 6 includes a second water pump 63, a second cleaning water pipe 64 and a nozzle 65. The second water pump 63 is installed in the waterway between the second cleaning water pipe 64 and the water storage container 5. The nozzle 65 is installed at the outlet of the second cleaning water pipe 64 and the injection port is directed toward the first fan 26, so that the first fan 26 is cleaned by condensed water.
