Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, a ventilation device for a kitchen provided by an embodiment of the present invention includes an air supply duct 1 and a control valve 5, wherein the air supply duct 1 penetrates through a wall of the kitchen, and is used for supplying fresh air into a cabinet 4 below a kitchen range 3 in the kitchen; the control valve 5 is arranged on the air supply pipeline 1.

Specifically, the kitchen ventilation device provided in this embodiment is used for being matched with a kitchen range 3 of a kitchen, wherein the air supply duct 1 is used for supplying fresh air into a cabinet 4 below the kitchen range 3, the air supply duct 1 penetrates through a wall of the kitchen, an air inlet of the air supply duct is located on the outer side of the wall of the kitchen, and an air supply outlet of the air supply duct is located in the cabinet 4 in the kitchen, that is, the air supply duct inputs the fresh air outside the wall into the cabinet 4 in the kitchen. The air supply pipeline 1 is provided with a control valve 5, the control valve 5 is opened and closed to control whether the air supply pipeline 1 sends fresh air or not, preferably, an air supply outlet of the air supply pipeline 1 is positioned below the kitchen range 3, so that the sent fresh air is guided to the kitchen range 3 under the drainage action of flame when the kitchen range 3 burns, and is sucked and exhausted by the oil smoke exhaust mechanism 2 after auxiliary combustion, preferably, such as a range hood, and optionally, an exhaust fan or other air exhaust structures in the prior art.

In this embodiment, it is preferable that the air inlet of the air supply duct 1 is provided with a filtering device, so as to ensure that no foreign matter is supplied to the cooker 3.

Optionally, the air inlet of the air supply duct 1 may be further provided with an insect prevention mechanism such as a filter screen or an insect prevention net, a rain prevention mechanism such as an arc-shaped rain shade, or a vertically downward air inlet structure, so as to prevent insects from entering the kitchen through the air supply duct 1, and prevent rainwater from entering the kitchen through the air supply duct 1.

The utility model provides a kitchen ventilation unit sends into the new trend to the kitchen through supply air duct 1, so guarantee the kitchen and even indoor be unlikely to the negative pressure state that is in that lasts, also solve the negative pressure from this and give the negative effects that culinary art and life brought, if the oil smoke pump drainage is convenient, maintain indoor pressure balance.

In another embodiment, it is preferable that the portion of the air supply duct 1 connected to the wall is provided with a sealing and heat insulating structure, such as a sealing strip or a sealing ring made of heat insulating material, so as to seal the air supply duct 1 to the wall, and reduce the heat exchange between the inside and the outside of the wall.

The utility model provides a still another embodiment, it is further, control flap 5 with the oil smoke pumping and discharging mechanism of kitchen links mutually, and the linkage refers to supply air duct 1 when oil smoke pumping and discharging mechanism 2 starts to open in step again here, and is optional, also can open earlier or open late.
