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 holes need 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. In addition, due to the limited space in the kitchen, the volume of the kitchen air conditioner cannot be too large. Therefore, there are major problems in the heat dissipation of the kitchen air conditioner. If the kitchen air conditioner cannot dissipate heat in time during use, 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 on the market, that is, air-conditioning components are added 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 relatively cumbersome. Moreover, the pipe and line connections 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 a water pipe. There is no other discharge method, and the condensed water has not been effectively utilized. Summary of the invention

The first heat exchanger 12 and the electrostatic purification device 5 are installed in the second smoke exhaust channel 222, and the electrostatic purification device 5 is arranged upstream of the first heat exchanger 12 along the oil fume flow direction, so as to prevent the oil fume from polluting the first heat exchanger 12.

[0027] In this embodiment, the first smoke exhaust channel 221 has a first smoke exhaust port 223 , and the second smoke exhaust channel 222 has a second smoke exhaust port 224 . The first smoke exhaust port 223 and the second smoke exhaust port 224 are independent of each other.

[0028] The housing 20 is provided with an air inlet 24 and a first air outlet 25, an air outlet passage 22 is formed between the air inlet 24 and the first air outlet 25, a second heat exchanger 13 and an air outlet fan 27 are installed in the air outlet passage 23, and the air outlet fan 27 is located upstream of the second heat exchanger 13 along the gas flow direction. The air inlet 24 is fluidly connected with the kitchen room or with the outside of the kitchen, the first air outlet 25 can be arranged at the top of the housing 20, or at the front of the housing 20, when the first air outlet is arranged at the top of the housing 20, the first air outlet is connected with the kitchen room through an air duct (not shown in the figure), when the first air outlet is arranged at the front of the housing 20, the air conditioning air is blown directly from the first air outlet to the kitchen room.

[0029] A second air outlet 26 is also provided on the casing 20 , which is connected to the kitchen room and is independent of the air outlet channel 23 and the smoke exhaust channel 22 . The second air outlet 26 is specifically provided on the cavity wall of the compressor installation cavity 28 , and an atomization device 3 is installed in the compressor installation cavity 28 .

[0030] The atomizing device 3 of this embodiment includes a water tank 31, a water pump 32, a water inlet pipe 33, an atomizing nozzle 34, a motor 35, an impeller 36, a water mist hood 37 and a water return pipe 38. The water tank 31 is arranged below the second heat exchanger 13 and is used to collect condensed water generated by the second heat exchanger 13. The water pump 32 is arranged in the water tank 31.

[0031] In addition, in order to reduce the refrigerant temperature, the refrigerant pipeline 14 between the compressor 11 and the first heat exchanger 12 is at least partially immersed in the condensed water inside the water tank 31 .

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

[0033] The range hood and the air conditioner are both turned on. In the cooling mode, the first heat exchanger 12 is a condenser, and the second heat exchanger 13 is an evaporator. The oil smoke is discharged through the second smoke exhaust channel 222. In addition, the oil 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 refrigerant 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 air outlet fan 27, cold air is sent into the kitchen from the first air outlet 25. At the same time, the atomizing device 3 is started, and the condensed water generated by the second heat exchanger 13 is atomized by the atomizing device 3 and blown out from the second air outlet 26 to humidify the kitchen.

[0034] In the heating mode, the first heat exchanger 12 is an evaporator and the second heat exchanger 13 is a condenser. At this time, the cold energy of the first heat exchanger 12 is discharged with the oil smoke, and warm air is blown out from the air outlet 25, and the second heat exchanger 13 no longer produces condensed water.

[0035] Only the range hood is turned on, and the oil smoke is discharged through the first smoke exhaust channel 221 .

[0036] In addition, the oil fume extraction component of the present invention is not limited to the structure of installing the oil fume extraction fan inside the casing. The oil fume extraction component can also adopt a non-powered structure, that is, the oil fume extraction component only retains the smoke collecting shell, and the oil fume fan is placed outside the casing. For example, the oil fume extraction fan can be installed on the top of the public flue of the building.

[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.
