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.

[0027] The oil fume extraction assembly of this embodiment has a housing 20, and an oil fume extraction fan 21 is arranged in the housing 20. The oil fume extraction fan 21 of this embodiment is a centrifugal fan installed at the lower part of the housing 20 and arranged horizontally. The upper part of the housing 20 is provided with a mutually isolated smoke exhaust channel 22 and an air outlet channel 23. Along the oil fume flow direction, the smoke exhaust channel 22 is arranged downstream of the air outlet of the oil fume extraction fan 21. Figure 1 The direction indicated by the middle arrow A is right, and the air outlet channel 23 is located on the right side of the smoke exhaust channel 22. The compressor 11 is arranged at the lower part of the casing 20 and integrated on the casing 20.

[0028] The smoke exhaust channel 22 of this embodiment includes a first smoke exhaust channel 221 and a second smoke exhaust channel 222. At the entrances of the first smoke exhaust channel 221 and the second smoke exhaust channel 222, an air duct switching valve 6 is installed for switching one of the first smoke exhaust channel 221 and the second smoke exhaust channel 222 to be connected to the air outlet of the oil fume exhaust fan 21. 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. In this embodiment, a first heat exchanger 12 and an electrostatic purification device 7 are installed in the second smoke exhaust channel 222, and the electrostatic purification device 7 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.

[0029] The housing 20 is provided with an air inlet 24 and an air outlet 25, and an air outlet channel 23 is formed between the air inlet 24 and the air outlet 25. An air outlet fan 26, a filter 27 and a second heat exchanger 13 are installed in the air outlet channel 23, and the filter 27, the second heat exchanger 13 and the air outlet fan 26 are arranged in sequence along the path of air flow. The air inlet 24 can be fluidly connected with the kitchen room, that is, indoor air intake is realized, and can also be fluidly connected with the kitchen room, that is, outdoor fresh air intake is realized; the air outlet 25 can be arranged on the front of the housing 20, that is, air is directly discharged from the front of the housing 20, and can also be arranged on the top of the housing 20, and connected with the air outlet holes on the kitchen ceiling through the air duct to realize ceiling air outlet.

[0030] A condensate collecting device is provided in the casing 20. In the present embodiment, the condensate collecting device is a water receiving tray 3 provided in the air outlet channel 23. The water receiving tray 3 is located below the second heat exchanger 13 and is used to collect condensate generated by the second heat exchanger 13. A water outlet 31 is provided on the water receiving tray 3.

[0031] A heating device is installed in the smoke exhaust passage 22. The heating device in this embodiment is an electric heating pipe 4 vertically or obliquely arranged in the smoke exhaust passage 22. The electric heating pipe 4 can be located upstream of the first heat exchanger 12 or downstream of the first heat exchanger 12. In this embodiment, the electric heating pipe 4 can be located downstream of the first heat exchanger 12.

[0032] A water groove 41 is formed on the outer wall of the electric heating tube 4, and the water outlet 31 of the water receiving tray 3 is connected to the water groove 41 through the water pipe 5. The water pipe 5 serves as a guide to guide the condensed water in the water receiving tray 3 to the water groove 41. After the water groove 41 is set, the water flow area of ​​the outer wall of the electric heating tube 4 can be increased to improve the evaporation efficiency. The water groove 41 of this embodiment is an annular groove distributed on the outer peripheral wall of the electric heating tube 4, and each annular groove is distributed in sequence along the length direction of the electric heating tube 4. In addition to the structure of this embodiment, the water groove can also adopt other different structures such as a threaded groove and a knurled groove.

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

[0034] 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 a condenser. The oil smoke is discharged through the second exhaust channel 222. In addition, the oil smoke airflow sweeping over the surface of the first heat exchanger 122 can cool down and dissipate the heat of the first heat exchanger 12, reduce 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 condensed water generated by the second heat exchanger 13 enters the water receiving tray 3, and after being guided by the water pipe 5, it flows through the water groove 41 on the surface of the electric heating tube 4 and is evaporated, and then discharged outward with the oil smoke, realizing the effective discharge of condensed water.

[0035] 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 no condensed water is generated in the air outlet channel 23.

[0036] Only the range hood is turned on, and the oil smoke is discharged through the first smoke exhaust channel 221 .

[0037] 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.

[0038] 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.
