As shown in fig. 1 to 3, a kitchen air conditioning system 1000 according to the present invention includes an air conditioner main unit 100, a range hood main unit 200, and a discharge fan 300. According to the utility model discloses a kitchen air conditioning system 1000 can independently use in the kitchen, and air conditioner host computer 100 has the refrigeration and/or heat function, can be used for changing the ambient temperature in the kitchen, and produced oil smoke when cigarette machine host computer 200 is used for the interior culinary art of suction kitchen, and exhaust fan 300 can derive the oil smoke that the cigarette machine smoked, provides the negative pressure for cigarette machine smoking oil smoke.

Among the correlation technique, the air conditioner integrated level in the kitchen is low, and spare part quantity is many, and cigarette machine and air conditioner all need lead the air current, but can't share same fan, and the air-out position limitation of air conditioner is big simultaneously, and the air-out position differs far away with the position of user when culinary art, can't guarantee the ambient temperature of user when the kitchen cooks. In addition, a kitchen always has some residual oil smoke smell after long-term use, if the air interchanger is installed to introduce outdoor fresh air into the kitchen, a part of space is occupied, and the whole pipeline connection is complex and troublesome. In order to solve the problem, according to the kitchen air conditioning system 1000 provided by the scheme of the application, the air conditioning main unit 100 and the smoke machine main unit 200 are highly integrated in structure and can be used for fresh air ventilation.

As shown in fig. 4-6, according to the utility model discloses an among the kitchen air conditioning system 1000, air conditioner host 100 includes first casing 10, first heat exchanger 20 and second heat exchanger 30, inject first heat transfer cavity 11 and second heat transfer cavity 12 in the first casing 10, first heat exchanger 20 is established in first heat transfer cavity 11 and is suitable for and carries out the heat transfer with the air current of flowing through first heat transfer cavity 11, second heat exchanger 30 sets up in second heat transfer cavity 12 and is suitable for and carries out the heat transfer with the air current of flowing through second heat transfer cavity 12, and can pass through refrigerant tube coupling between first heat exchanger 20 and the second heat exchanger 30, be provided with spare parts such as compressor 40 and throttle piece on the refrigerant pipeline, so that first heat exchanger 20 and second heat exchanger 30 can accomplish the carnot cycle.

Specifically, an air-conditioning blower 71 is disposed in the first heat exchange chamber 11, and when the air-conditioning blower 71 operates, air is sucked from the first air return opening 11a and air flow is blown out from the first air outlet opening 11 b.

As shown in fig. 9-11, the main body 200 of the range hood includes a second cabinet 210 and an oil filter 220. The second housing 210 has a smoke channel 211 therein, and the oil filter 220 is disposed in the smoke channel 211, for example, the oil filter 220 may be disposed at a smoke inlet 211a of the smoke channel 211. The smoke channel 211 has a smoke inlet 211a and a smoke outlet 211b, wherein the smoke inlet 211a and the smoke outlet 211b are both formed on the second housing 210, and the oil filter 220 can filter the smoke in the smoke channel 211, so as to achieve the basic smoke absorbing and oil filtering function of the main body 200 of the range hood.

A heat exchange air duct 212 is further arranged in the second casing 210 of the range hood main unit 200, the heat exchange air duct 212 has an air conditioner air outlet 212a and an air conditioner air inlet 212b, the air conditioner air outlet 212a and the air conditioner air inlet 212b are both arranged on the second casing 210, and the air conditioner air inlet 212b is communicated with the first air outlet 11b through an air outlet pipe 903.

The low-temperature or high-temperature airflow generated by the air conditioner main unit 100 can be transmitted to the heat exchange air duct 212 in the cigarette machine main unit 200 through the air outlet pipe 903, and is blown to a kitchen or even a direct-blowing user from the cigarette machine main unit 200 through the air conditioner air outlet 212a of the heat exchange air duct 212, so that the kitchen temperature of the user in the cooking process is effectively improved, and the cooking comfort of the user is improved.

Through the arrangement of the heat exchange air duct 212 on the second casing 210 of the main unit 200 of the cigarette machine, the air flow generated by the main unit 100 of the air conditioner can be blown to the user through the main unit 200 of the cigarette machine. When the air outlet 212a of the air conditioner is located on the second housing 210, the air outlet range of the air conditioner is substantially located in the cooking area of the user, and the air outlet range can be more adaptive to the working position of the user, so that the arrangement of the kitchen air conditioning system 1000 is more concise.

The exhaust fan 300 is connected to the second air outlet 12b and the flue outlet 211b, respectively, to guide out the air in the second heat exchange chamber 12 and the air in the oil smoke channel 211.

The exhaust fan 300 can simultaneously act on the range hood main unit 200 and the air conditioner main unit 100 to respectively provide power for the flow of the air flow in the oil smoke channel 211 and the second heat exchange chamber 12, and the exhaust fan 300 can selectively serve the range hood main unit 200 or the air conditioner main unit 100. Exhaust fan 300 set up make the gas after the heat transfer of second heat transfer cavity 12, the flue gas of oil smoke passageway 211 after filtering, can be driven by exhaust fan 300 and discharge towards outdoor flow, the integration makes the flow of air in second heat transfer cavity 12 like this, the flow of flue gas is discharged by exhaust fan 300, and the discharge of so setting up back two strands of gas can set up same pipe-line system, thereby not only can reduce part quantity, and reduce pipeline length, make the pipe connection simpler.

Referring to fig. 5 to 7, the second air return opening 12a is connected to a fresh air duct 901, and the second air return opening 12a can communicate with the space outside the kitchen through the fresh air duct 901, so that the second heat exchange chamber 12 can suck air in the space outside the kitchen. The other end of the fresh air duct 901 is connected to a position without limitation, and in the example of fig. 1, one end of the fresh air duct 901 is connected to the second return air inlet 12a, and the other end extends rightward and can be communicated to the outside. There are also solutions in which the fresh air duct 901 may extend from the second return air inlet 12a toward other rooms, for example, to communicate with a living room or the like. The arrangement can not only suck air in other rooms into the air conditioner main unit 100 to exchange heat with the second heat exchanger 30, but also promote air in other rooms to flow, at the moment, windows of other rooms are opened, and the pressure difference enables external fresh air to be filled into the rooms to achieve air circulation of the rooms.

The first housing 10 is provided with a fresh air port 14 for communicating the first heat exchange chamber 11 and the second heat exchange chamber 12, and the first housing 10 is further provided with a fresh air switch assembly 60 for switching the fresh air port 14. Therefore, when the fresh air port 14 is opened, the first heat exchange chamber 11 can be replenished with fresh air through the second heat exchange chamber 12, and when the fresh air needs to be replenished into the first heat exchange chamber 11, the first air return port 11a of the first heat exchange chamber 11 is not needed to be communicated with the outside. Therefore, the fresh air sucked by the fresh air pipeline 901 can be supplied to the second heat exchange chamber 12 and the first heat exchange chamber 11.

Because exhaust fan 300 can drive flue gas in oil smoke passageway 211 and flow in the scheme of this application, also can drive air flow in the second heat transfer chamber 12, because of exhaust fan 300's a quick-witted double-purpose, consequently can set up multiple using-way as required. For example, the communication between the exhaust fan 300 and the oil smoke passage 211 and the second heat exchange chamber 12 can be only an alternative mode (for example, the three are connected by a switchable three-way valve), when the exhaust fan 300 is communicated with the oil smoke passage 211, the communication between the exhaust fan 300 and the second heat exchange chamber 12 is completely cut off; when the exhaust fan 300 is communicated with the second heat exchange chamber 12, the communication between the exhaust fan 300 and the soot passage 211 is completely cut off, so that the heat exchange and the soot extraction can be performed only separately. In another scheme, when the exhaust fan 300 operates, gas is simultaneously sucked from the oil smoke channel 211 and the second heat exchange chamber 12, so that heat exchange and oil smoke extraction can be performed simultaneously. In another embodiment, the kitchen air conditioning system 1000 further includes a ratio adjusting device for adjusting the ratio of the oil smoke channel 211 and the second heat exchange chamber 12 to suck air when the exhaust fan 300 operates, so that the kitchen air conditioning system 1000 can perform heat exchange and oil smoke extraction separately, and also perform heat exchange and oil smoke extraction simultaneously.

When the air conditioner blowing fan 71 operates, air is sucked into the first heat exchange chamber 11 from the first air return opening 11a, the sucked air flows through the first heat exchanger 20, the temperature of the sucked air is reduced, low-temperature air is blown into the heat exchange air duct 212 of the range hood main body 200 from the first air outlet opening 11b through the air outlet pipe 903, and finally the low-temperature air is blown out from the air conditioner air outlet opening 212 a. When the exhaust fan 300 is operated, the driving air is sucked from the first air return opening 11a, the temperature of the sucked air is lowered by passing through the first heat exchanger 20, the low temperature air is sucked from the fresh air duct 901 and the second air return opening 12a into the second heat exchange chamber 12, the temperature of the sucked air is raised by passing through the second heat exchanger 30, and the high temperature air can be exhausted from the exhaust duct 902.

In the smoke exhaust mode, the exhaust fan 300 operates to drive the smoke to be sucked into the smoke passage 211 from the smoke inlet 211a, and then to be exhausted through the exhaust fan 300 and the exhaust duct 902.

In the fresh air mode, the fresh air opening 14 is opened by the fresh air switch assembly 60, and the air conditioner blower 71 is operated. When the air-conditioning blowing fan 71 operates, fresh air is sucked into the first heat exchange chamber 11 through the fresh air pipeline 901, the second air return opening 12a, the second heat exchange chamber 12 and the fresh air port 14 in sequence, the sucked air is blown into the heat exchange air duct 212 of the range hood main unit 200 through the air outlet pipeline 903 from the first air outlet 11b, and finally the fresh air is blown out from the air-conditioning air outlet 212 a.

Fresh air mode and oil extraction cigarette mode can go on simultaneously in this scheme, and compressor 40 does not operate this moment, and air conditioner blower 71, discharge fan 300 all operate, and fresh air switch subassembly 60 opens fresh air opening 14. When the air-conditioning blowing fan 71 operates, fresh air is sucked into the first heat exchange chamber 11 through the fresh air pipeline 901, the second air return opening 12a, the second heat exchange chamber 12 and the fresh air port 14 in sequence, the sucked air is blown into the heat exchange air duct 212 of the range hood main unit 200 through the air outlet pipeline 903 from the first air outlet 11b, and finally the fresh air is blown out from the air-conditioning air outlet 212 a. The exhaust fan 300 operates to drive the soot to be sucked into the soot passage 211 from the soot inlet 211a and then to be exhausted through the exhaust fan 300 and the exhaust duct 902.

Of course, the galley air conditioning system 1000 may have more modes, or a combination of more modes, as the components described above have other forms. In some embodiments, the kitchen air conditioning system 1000 further has a heating mode, a dehumidification mode, and the like, which are not described in detail herein.
