That is, the wind guide cover plate 44 can adjust the direction of the blown wind, and the wind direction can be adjusted by adjusting the included angle between the wind guide cover plate 44 and the wind outlet 422 (i.e. the degree of the outward turning of the wind guide cover plate 44), and the smaller the included angle is, the more the wind goes downwards. (the included angle is preferably 47 degrees). The blowing assembly 4 uses the blowing fan 41 to perform air draft and supply, uses the heater 43 to heat the supplied air, and uses the air guide cover plate 44 to adjust the direction of the blown air, and has the advantages of simple structure, no need of complex structure, low cost, stability, reliability, convenient use and low power consumption.

The range hood of the utility model is provided with two sets of air duct systems which are respectively independent. One is a smoke exhaust module 3 (described in detail below) for exhausting smoke and fume outwards: after the oil smoke extraction component 3 is opened, various oil smoke, moisture, spicy flavor and other oil stain gases generated by cooking and cooking are sucked and discharged. It is second the subassembly 4 of blowing that is used for cooling and heating: in hot weather, the blowing fan 41 is started, clean air is extracted from the top of the range hood by the blowing fan 41, cool air is sent out through the air guide pipeline 42, and the cool air is blown to the 47-degree position right in front of the range hood from the air outlet 422 and onto the body of a person, so that the cooling purpose is achieved; in cold weather, the heater 43 is turned on while the blowing fan 41 is turned on, warm air is sent out through the air guide duct 42, and the warm air is blown to the position 47 degrees in front of the range hood from the air outlet 422 and then blown to the human body, so that the temperature rise purpose is achieved.

In order to make the blowing fan 41 draw clean air, the blowing assembly 4 is located above the smoke suction chamber 2, and the blowing assembly 4 and the smoke suction chamber 2 are isolated from each other, i.e. the blowing fan 41 draws clean air from the upper part of the room without drawing air containing smoke.

The wind guide cover plate 44 can be opened and closed when in use and closed when not in use, has an attractive effect except for adjusting the wind outlet direction, and also has the functions of dust prevention and insect prevention, so that the wind guide pipeline 42 is kept clean, and the wind blowing component 4 blows the wind on the human body cleanly.

In a more specific embodiment of the present invention, as shown in fig. 3, the blower fan 41 is preferably a centrifuge in order to provide a large air volume, high efficiency and low noise. The blowing fan 41 comprises a volute 411, a fan motor 412 is arranged in the volute 411, an impeller 413 is arranged at the output end of the fan motor 412, suction openings 414 are respectively arranged on the left side and the right side of the volute 411, and a filter screen 415 is arranged on each suction opening 414. The filter screen 415 has a function of adsorbing oil smoke, dust, cilia and the like, and can clean air.

Preferably, as shown in the figure, a U-shaped opening 4151 (convenient for hooking and screwing) is arranged at the edge of the filter screen 415 so as to be capable of being aligned and assembled and disassembled quickly.

In a more specific embodiment of the present invention, a first flange 416 is disposed at the air suction opening 414 on a side of the scroll 411 facing away from the output end of the fan motor 412, an air guiding ring 417 is disposed at the air suction opening 414 on a side of the scroll 411 close to the output end of the fan motor 412, and a second flange 4171 is disposed on the air guiding ring 417. Both the first flange 416 and the second flange 4171 reduce noise and increase static pressure.

In a more specific embodiment of the present invention, the blower fan 41 is covered with a protective cover 46, and the top or upper part of the protective cover 46 is provided with an opening for air intake. This is to further enable the blower fan 41 to suck the cleanest air in the kitchen, that is, to locate the suction inlet (i.e., the opening for air intake) on the top of the range hood (i.e., the top or upper portion of the protective cover 46), and the air sucked by the blower fan 41 is air in the upper portion of the kitchen, relatively fresh, far away from the cooktop and the smoke exhaust module 3, and free of smoke.

In a more specific embodiment of the present invention, in order to make the duct of the air duct system have low resistance, short length, and smooth switching, the blowing fan 41 is a vertical fan with a downward output, so that the duct is less bent and the ventilation is smooth.

Of course, the blower 41 may also be horizontal, and the air inlet thereof is preferably upward, and a filter screen is disposed at the air inlet.

In a more specific embodiment of the present invention, the corner position of the air guiding duct 42 has an arc-shaped transition surface 423. Therefore, the air duct is smooth, the air flows smoothly, and the energy loss is reduced. Of course, as shown in fig. 5, in order to uniformly blow out the wind from the wind outlet 422, the left side wall 424 and the right side wall 425 of the wind guide duct 42 are transition surfaces having slopes so that the airflow is diffused to the left and right.

In a more specific embodiment of the present invention, as shown in fig. 4, the first opening/closing driving device 45 includes a first driving motor 451 fixed to the housing 1, a first link assembly 452 connecting an output end of the first driving motor 451 and a lower portion of the wind guide cover 44 is provided, and an upper portion of the wind guide cover 44 is hinged to the housing 1. The first link assembly 452 includes two links, wherein two ends of one link are respectively rotatably connected to the lower portion of the air guiding cover plate 44 and one end of the other link, and the other end of the other link is connected to the output end of the first driving motor 451. When the first driving motor 451 rotates, the lower portion of the air guiding cover plate 44 is driven to turn inside and outside, so that the air guiding cover plate 44 is automatically opened and closed.

In a more specific embodiment of the present invention, the smoke exhaust module 3 includes a suction centrifuge 31, an inclined smoke panel 32 is disposed in front of the suction centrifuge 31, a smoke grid opening 33 is disposed on the smoke panel 32, a smoke collecting plate 34 capable of opening and closing the smoke grid opening 33 is disposed at the smoke grid opening 33, and the smoke collecting plate 34 is connected to a second opening and closing driving device (not shown in the figure) capable of driving the smoke collecting plate to open and close. The suction centrifuge 31 sucks the oil smoke generated during cooking from the smoke grill port 33 and discharges the oil smoke to the outside through the smoke discharge duct. The smoke collecting plate 34 has a smoke collecting function, namely, blocks oil smoke, so that cooking oil smoke is completely sucked at the smoke sucking grid opening 33 and cannot rise and escape. In addition, the smoke collecting plate 34 can also block the air blown out from the air outlet 422, so as to prevent the suction-discharge centrifuge 31 from sucking away the air blown out from the air outlet 422.

Preferably, in order to further allow the blower fan 41 to draw clean air, the suction centrifuge 31 of the smoke evacuation module 3 is provided at a lower portion of the smoke evacuation chamber 2.

In a more specific embodiment of the present invention, the air outlet 422 is located between the air guiding cover plate 44 and the cigarette collecting plate 34. The air blown out from the air outlet 422 can form an air curtain to prevent outside air from flowing into the smoke suction grid opening 33, so that the smoke collecting effect is achieved, and the smoke suction effect of the smoke suction assembly 3 is improved.

Preferably, the second opening and closing driving device (not shown in the drawings, and the structure is similar to the first opening and closing driving device 45) includes a second driving motor fixed on the housing 1, a second connecting rod assembly connecting the output end of the second driving motor and the lower portion of the cigarette collecting plate 34 is provided between the output end of the second driving motor and the lower portion of the cigarette collecting plate 34 (the structure of the second connecting rod assembly is similar to the first connecting rod assembly 452, and is not described here again), and the upper portion of the cigarette collecting plate 34 is hinged on the housing 1.
