The second driving unit may be a rotary driving unit, such as a motor 1342 or a rotary driving unit formed by a combination of the motor 1342 and the connecting rod assembly. It is understood that the structure of the second switch member may be similar to the structure of the first switch member 130 shown in fig. 3 to 5, and the detailed description thereof is omitted.

In use, heat generated by the air conditioning assembly can enter the second mounting cavity 212 along the air inlet hole and be exhausted to the smoke exhaust hole along the air outlet of the first fan 230. The oil smoke in the kitchen can enter the second installation cavity 212 along the smoke inlet, enter the first fan 230 along the first through hole 244 or the second through hole, and be discharged to the smoke exhaust hole along the air outlet of the first fan 230.

Further, referring to fig. 6, the cigarette maker construction 200 further includes a third switch 250, the third switch 250 is used for opening or closing the first through hole 244, and the third switch 250 is in communication with the controller. Thus, the third switch 250 can control the first via 244 to be turned on or off. For example, when the pressure of the range hood 10 absorbing the oil smoke is not large, the third switch 250 may be controlled to close the first through hole 244; at this time, the oil smoke is only sucked to the first fan 230 along the second through hole; when the pressure of the range hood 10 absorbing the oil smoke is relatively high, the third switch 250 can open the first through hole 244, and at this time, the oil smoke can be simultaneously sucked into the first fan 230 along the first through hole 244 and the second through hole.

Of course, the third switching part 250 may also have a structure similar to that of the first switching part 130 shown in fig. 3 to 5. Alternatively, the first switch member 130, the second switch member, and the third switch member 250 may be all switch members of the same type.

The air conditioning assembly 120 includes a condenser 122. when the air conditioning assembly 120 is in operation, particularly when the air conditioning assembly 120 is in a cooling mode, the condenser 122 generates a large amount of heat, and it is desirable to quickly dissipate the heat from the condenser 122. In order to exhaust the heat of the condenser 122, it is generally considered that the heat of the condenser 122 is transferred into the second installation cavity 212 along the exhaust hole 114 and exhausted to the outside along the exhaust hole.

Referring to fig. 1 and 2, in some embodiments, the air outlet end of the condenser 122 faces the air outlet hole 114 or the condenser 122 is disposed in the air outlet hole 114, the air conditioning structure 100 further includes a second fan 140, and the air outlet end of the second fan 140 faces the condenser 122. At this time, the heat generated from the condenser 122 can be rapidly discharged into the second installation cavity 212 by the second fan 140.

It will be appreciated that the range hood 10 does not require the second fan 140 to be in operation at all times. When the range hood 10 is used, the temperature of the condenser 122 can be detected, and when the temperature of the condenser 122 reaches a preset value, the second fan 140 is started to dissipate heat of the condenser 122. At this time, the second fan 140 needs to be in communication with the controller, the controller receives the temperature information of the condenser 122, and the operation of the second fan 140 is controlled according to the temperature information.

Specifically, referring to fig. 7, the second fan 140 includes a fourth driving unit 142 and a blade 144, the fourth driving unit 142 drives the blade 144 to rotate, and the fourth driving unit 142 is in communication connection with the controller. Alternatively, the fourth driving unit 142 may be a motor 1342.

Based on the foregoing description of the embodiment, the range hood 10 has three modes, which are the air conditioning mode of independent operation, the smoke absorption mode of independent operation, and the air conditioning mode and the smoke absorption mode of simultaneous operation.

When the range hood 10 is in the single-operation range hood mode, the second driving unit drives the second baffle to open the smoke inlet, the first fan 230 is turned on, the third driving unit 254 drives the third baffle 252 to open the first through hole 244, the fourth driving unit 142 is in the closed state, that is, the second fan 140 is in the closed state, and the first driving unit 134 drives the first baffle 132 to close the air outlet 114, so as to prevent the oil smoke from entering the first mounting cavity 112 along the smoke inlet and being conveyed to the kitchen. At this time, under the action of the first fan 230, the oil smoke may enter the second installation cavity 212 through the smoke inlet and enter the first fan 230 along the second through hole, and a part of the oil smoke may also enter the first fan 230 through the first through hole 244 and finally be discharged from the smoke outlet.

When the range hood 10 is in the air conditioning mode of single operation, the third driving unit 254 drives the third baffle 252 to open the first through hole 244, the first fan 230 is started, the first driving unit 134 drives the first baffle 132 to open the air outlet 114, and the second driving unit drives the second baffle to close the smoke inlet, so as to prevent the oil smoke from entering the second installation cavity 212 along the smoke inlet and entering the first installation cavity 112 along the air outlet 114 to be delivered to the kitchen. In this mode, the first fan 230 is operated at a low speed, so that hot air is drawn out. The wind passes through the condenser 122 from above the condenser 122 to take away the heat of the condenser 122, and then turns into hot wind, after the hot wind enters the second installation cavity 212 along the wind discharging hole 114, a part of the hot wind can enter the first fan 230 from the second through hole, and another part of the hot wind can enter the first fan 230 from the first through hole 244, and finally is discharged from the smoke discharging hole.

When the range hood 10 is in the air conditioning mode and the oil smoke suction mode, the second driving unit drives the second baffle to open the smoke inlet, the first fan 230 is started, the first driving unit 134 drives the first baffle 132 to open the air outlet 114, and the third driving unit 254 drives the third baffle 252 to close the first through hole 244, so that the oil smoke entering the second mounting cavity 212 along the smoke inlet is prevented from entering from the first through hole 244 and restricting the normal circulation of the air entering the second mounting cavity 212 along the air outlet, and the heat dissipation of the condenser 122 is affected. The oil smoke enters the second installation cavity 212 along the smoke inlet and enters the first fan 230 along the second through hole together with the hot air, and finally is discharged from the smoke outlet.

In the aforementioned three modes, after the first driving unit 134 drives the first shutter 132 to open the exhaust hole 114, the controller continuously receives the temperature information of the condenser 122, and when the temperature of the condenser 122 is higher than a predetermined critical temperature (e.g., 60 ℃), the fourth driving unit 142 is turned on to drive the blades 144 to rotate, thereby improving the heat dissipation efficiency of the condenser 122.

Referring to fig. 2 and 3, in some embodiments, the air conditioning structure 100 further includes a mounting bracket 150, the condenser 122 is installed in the exhaust hole 114, the second fan 140 is connected to the inner wall of the first mounting cavity 112 through the mounting bracket 150, and the air outlet end of the second fan 140 and the condenser 122 are disposed at an interval along the depth direction of the first mounting cavity 112, wherein the depth direction of the first mounting cavity 112 is shown as F in fig. 1. In this manner, the second fan 140 is mounted by the mounting bracket 150.

Further, referring to fig. 2 and 3, the mounting bracket 150 is formed with a mounting through hole 1562, the mounting through hole 1562 faces the air exhausting hole 114 and is spaced apart from the air exhausting hole 114 along the depth direction of the first mounting cavity 112, or the mounting through hole 1562 is in butt communication with the air exhausting hole 114, and the second fan 140 is disposed in the mounting through hole 1562. The installation through holes 1562 can realize installation of the second fan 140, and can also realize collection of air blown by the second fan 140, so as to increase the amount of air blown to the condenser 122 by the second fan 140.

Referring to fig. 2 and 3, in one embodiment, the mounting bracket 150 includes a first section of bracket 152, a second section of bracket 154, and a third section of bracket 156, the first section of bracket 152 is connected to the third section of bracket 156 through the second section of bracket 154, the first section of bracket 152 and the second section of bracket 154 are respectively connected to the bottom wall of the first mounting cavity 112 at two sides of the exhaust hole 114, the third section of bracket 156 and the exhaust hole 114 are arranged at intervals along the depth direction of the first mounting cavity 112, and the third section of bracket 156 is provided with mounting through holes 1562.
