Description

Technical Field

[0001] The invention relates to a kitchen air conditioning system. Background Art

[0002] 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.

[0003] 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 indoor unit of the traditional air conditioner with the traditional range hood, and the outdoor unit of the air conditioner still needs to be installed separately outdoors. The integration of this type of air-conditioning range hood is not enough, and the installation is relatively cumbersome. Moreover, the pipe and line connection between the indoor and outdoor units of the air conditioner will also damage the wall. In addition, the air inlet of the existing kitchen air conditioner is connected to the kitchen. Since the air in the kitchen is relatively poor, it is difficult to blow out sufficiently fresh air from the air outlet, and the user experience needs to be further improved.

[0022] The present invention is further described in detail below with reference to the accompanying drawings.

[0023] Embodiment 1:

[0024] like Figures 1 to 3As 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 throttling device 15 is installed on the refrigerant pipeline 14 between the first heat exchanger 12 and the second heat exchanger 13. 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.

[0025] The oil fume extraction assembly of this embodiment has a housing 20, in which an oil fume extraction fan 21 is arranged. The oil fume extraction fan 21 is installed at the lower part of the housing 20. The upper part of the housing 20 is provided with a mutually isolated smoke exhaust passage 22 and an air outlet passage 23. Along the oil fume flow direction, the smoke exhaust passage 22 is arranged downstream of the air outlet of the oil fume extraction fan 21. 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. A compressor installation cavity 27 isolated from the smoke exhaust channel 22 and the air outlet channel 23 is provided inside the casing 20, and the compressor 11 is installed in the compressor installation cavity 27.

[0026] 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 fume exhaust fan 21. In addition, the first smoke exhaust channel 221 and the second smoke exhaust channel 222 each have an independent smoke exhaust port. In this embodiment, a first heat exchanger 12 and an 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 flow direction of the fume, so as to prevent the fume from polluting the first heat exchanger 12.

[0027] The housing 20 is provided with an air inlet 24 and an air outlet 25, and an air outlet passage 23 is formed between the air inlet 24 and the air outlet 25. In this embodiment, a second heat exchanger 13 and an air outlet fan 26 are installed in the air outlet passage 23, and along the gas flow direction, the second heat exchanger 13 is arranged downstream of the air outlet fan 26. The air outlet 25 can be arranged at the top of the housing 20 or at the front of the housing 20. When the air outlet of this embodiment is arranged at the top of the housing 20, the air outlet is connected to the kitchen room through an air duct (not shown in the figure).

[0028] The air inlet of this embodiment has a first air inlet portion 241 and a second air inlet portion 242 that are isolated from each other. The first air inlet portion 241 is connected to the fresh air passage 3, and the second air inlet portion 242 is connected to the kitchen room.

[0029] A wind valve mechanism is installed in the fresh air passage 3 to control whether the first air inlet 241 is connected to or isolated from the outside. The wind valve mechanism of this embodiment includes a first valve plate 41, a motor 42 and a push rod 43, wherein the first valve plate 41 is arranged in the fresh air passage 3, the motor 42 is arranged outside the fresh air passage 3, the push rod 43 is installed on the drive output shaft of the motor 42, and the head of the push rod 43 is arranged in the fresh air passage 3 and connected to the first valve plate 41. In addition, a second valve plate 44 is also installed in the first air inlet 241, such as Figure 2 As shown, when the second valve plate 44 is in a vertical position, the first air inlet portion 241 is closed, and when the second valve plate 44 is in an inclined position, the first air inlet portion 241 is opened.

[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, the second heat exchanger 13 is an evaporator, and the oil smoke is discharged through the second smoke exhaust channel 222. In addition, the oil smoke airflow sweeps over the surface of the first heat exchanger 12 to 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 from the air outlet 25.

[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 along with the oil smoke, and warm air is blown out from the air outlet 25.

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

[0034] In addition, when the first valve plate 41 and the second valve plate 44 are opened, outdoor fresh air enters the air outlet channel 23 through the fresh air channel 3, thereby providing fresh air to the kitchen room. When the first valve plate 41 and / or the second valve plate 44 are closed, outdoor fresh air cannot enter the air outlet channel 23.

[0035] 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.

[0036] Embodiment 2:

[0037] like Figure 4As shown, the air inlet 24 of the air outlet channel of this embodiment becomes the common air inlet portion of the fresh air channel 3 and the kitchen room, and a fan 45 and a third valve plate 46 are installed in the fresh air channel 3, and along the fresh air flow direction, the third valve plate 46 is arranged downstream of the fan 45. A spring 47 is installed on the third valve plate 46, and when the fan 45 is not started, the third valve plate 46 closes the fresh air channel 3 under the elastic force of the spring 47, and when the fan 45 is started, the third valve plate 46 overcomes the elastic force of the spring 47 under the wind force of the fan 45 and opens the fresh air channel 3.

[0038] When the system is working, the fan 45 is turned on, the third valve plate 46 swings down, and the outdoor fresh air enters the air outlet channel 23 through the fresh air channel 3, thereby providing fresh air to the kitchen. The fan 45 is closed, and the third valve plate is reset to a horizontal position under the action of the spring 37, the fresh air channel 3 is closed, and the outdoor fresh air cannot enter the air outlet channel 23. The remaining structures and corresponding working principles of this embodiment are the same as those of the first embodiment, and will not be described in detail here.

[0039] 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.
