[0019] The utility model will be further described in detail in combination with the drawings.

[0020] As Figures 1 to 3 shown, the refrigeration type range hood of the embodiment comprises a casing 1, and the casing 1 is integrated with a range hood module and a refrigeration module. The range hood module comprises a range hood fan 7, and the range hood fan 7 of the embodiment is a vertical centrifugal fan, the central axis of the impeller of the range hood fan 7 extends forward and backward and is perpendicular to the front face of the casing 1, and the range hood fan 7 has front and rear double air inlet structures, that is, has a front air inlet 71 and a rear air inlet 72.

[0021] As Figure 4 shown, the refrigeration module comprises a compressor 81, a condenser 82, an evaporator 83, a heat dissipation fan 84 and an indoor fan 85, the compressor 81, the condenser 82 and the evaporator 83 are connected in communication through a refrigerant pipeline 86, the heat dissipation fan 84 is used to dissipate heat for the condenser 82, and the indoor fan 85 is used to blow out cold air on the side of the evaporator 83.

[0022] In this embodiment, the top of the casing 1 is provided with a heat dissipation air inlet, which is connected to the air inlet of the cooling fan 84. The air outlet of the cooling fan 84 is connected to the air inlet of the range hood 7. The top of the casing 1 is also provided with an indoor unit air inlet, and the front of the casing 1 is provided with an air conditioning outlet 4. The indoor unit air inlet is connected to the air inlet of the indoor unit fan 85, and the air outlet of the indoor unit fan 85 is connected to the air conditioning outlet 4. When operating in cooling mode, the heat of the condenser 82 is carried away by the range hood 7, and at the same time, cold air is blown out from the air conditioning outlet 4.

[0023] In this embodiment, a first smoke inlet 2 is provided at the lower part of the casing 1, and the first smoke inlet 2 is the main smoke inlet. In this embodiment, the first smoke inlet 2 is arranged obliquely downward from front to back, and a smoke baffle 3 is provided on the front side of the first smoke inlet 2. The smoke baffle 3 flips upward to open the first smoke inlet 2, and flips downward to close the first smoke inlet 2. When the smoke baffle 3 flips upward to its maximum angle, the smoke baffle 3 is arranged obliquely forward from top to bottom.

[0024] The second smoke inlet 5 is located adjacent to and above the smoke baffle 3. The second smoke inlet 5 is an auxiliary smoke inlet, and its air intake area is smaller than that of the first smoke inlet 51. An air conditioning outlet 4 is located above the second smoke inlet 5. A damper 6 is installed at the second smoke inlet 5; switching the damper 6 allows the second smoke inlet 5 to be opened or closed. The second smoke inlet 5 has an inclined guide channel 51 adjacent to the smoke baffle 3. Along the direction of smoke flow, the inclined guide channel 51 extends backward and upward. When the smoke baffle 3 is open, the smoke intake direction of the inclined guide channel 51 is consistent with the inclination direction of the smoke baffle 3.

[0025] like Figure 2 As shown, when both the range hood and air conditioner are on, the first smoke inlet 2, the second smoke inlet 5, and the air conditioner outlet 4 are all open. The first smoke inlet 2 is connected to the rear air inlet 72, and the second smoke inlet 5 is connected to the front air inlet 71. At this time, when the fumes rising from the pot 9 overflow along the baffle plate 3, the overflowing fumes enter the negative pressure zone and are drawn into the second smoke inlet 5 by the range hood 7 and discharged outdoors.

[0026] like Figure 3 As shown, when the range hood is turned on but the air conditioner is not turned on, the cooling module does not work, the first smoke inlet 2 is open, and the second smoke inlet 5 and the air conditioner outlet 4 are closed. The oil fumes drawn in from the first smoke inlet 2 can enter the range hood 7 simultaneously through the front air inlet 71 and the rear air inlet 72. That is, the front and rear air inlets of the range hood 7 simultaneously draw in oil fumes, which enhances the oil fume extraction effect.
