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 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 there is no other discharge method.

Common refrigerants can be water, ethylene glycol or propylene glycol, etc. The specific working principle of the air conditioning component 1 is the same as that of the existing air conditioner, and will not be described in detail here.

[0024] The oil fume extraction assembly of this embodiment has a housing 20, and an oil fume extraction fan 21 is installed at the lower part of the housing 20. The oil fume extraction fan 21 of this embodiment adopts a horizontally arranged centrifugal fan. The upper part of the housing 20 is provided with a mutually isolated exhaust passage 22 and an air outlet passage 23. Along the gas flow direction, the exhaust passage 22 is arranged downstream of the oil fume extraction fan 21 to Figure 1 The direction indicated by the middle arrow B is right, and the air outlet channel 23 is located on the right side of the smoke exhaust channel 22 and above the range fumes suction fan 21 .

[0025] The smoke exhaust channel 22 of this embodiment includes a first smoke exhaust channel 221 and a second smoke exhaust channel 222. An air duct switching valve 5 is installed at the entrance of the first smoke exhaust channel 221 and the second smoke exhaust channel 222 to switch one of the first smoke exhaust channel 221 and the second smoke exhaust channel 222 to be connected to the air outlet of the range fumes fan 21.

[0026] Both the first smoke exhaust channel 221 and the second smoke exhaust channel 222 have a transverse smoke exhaust section, and the transverse smoke exhaust section of the first smoke exhaust channel 221 is located above the transverse smoke exhaust section of the second smoke exhaust channel 222. The first heat exchanger 12 and the electrostatic purification device 6 are installed in the second smoke exhaust channel 222, and the electrostatic purification device 6 is arranged upstream of the first heat exchanger 12 along the path of the oil smoke flow, so as to prevent the oil smoke from polluting the first heat exchanger 12.

[0027] The housing 20 is provided with an air inlet 24 and an air outlet 25 of the air outlet passage 23. The air inlet 24 can be connected to the kitchen room or to the outside of the kitchen so that outdoor fresh air enters the air outlet passage 23. The air outlet 25 is located at the front of the housing 20 or at the top of the housing 20. The second heat exchanger 13 and the air outlet fan 26 are installed in the air outlet passage 25, and the air outlet fan 26 is located downstream of the second heat exchanger 13 along the gas flow direction.

[0028] In this embodiment, the compressor 11 is integrated on the casing 20 and is located outside the smoke exhaust passage 22 and the air outlet passage 23, so that the system structure is more compact and the installation is more convenient.

[0029] An atomizer 3 is installed inside the housing 20. The atomizer 3 is located in the second smoke exhaust channel 222 and rotates synchronously with the range fumes suction fan 21 under the drive of the driving mechanism. The atomizer 3 is used to atomize the condensed water generated by the second heat exchanger 13 into the second smoke exhaust channel 22.

The water spray pipe 33 is installed on the water outlet of the water pump 32, and the water outlet of the water spray pipe 33 faces the atomizing tray 34.

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

[0031] 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 26, cold air is sent into the kitchen room from the 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 enters the second smoke exhaust channel 222, thereby realizing the smooth discharge of the condensed water.

[0032] 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.

[0033] Only the range hood is turned on, and the oil smoke is discharged through the first smoke exhaust channel 221 .

[0034] 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.
