Description

Range hood with negative pressure cavity

Technical Field

The utility model relates to a range hood with a negative pressure cavity.

Background

The kitchen ventilator is also called as a range hood, and is a kitchen appliance for purifying the kitchen environment. The existing range hood comprises a top suction type and a side suction type, wherein the top suction type range hood uses the principle of hot gas rising to suck and discharge naturally rising oil smoke generated during cooking; the side-draft range hood absorbs most of the oil smoke close to the cooking bench in an arc form by using the vortex wind pressure principle; however, in the existing side-draft range hood, part of the oil smoke escapes and cannot be sucked into the range hood, so that the range hood has poor oil smoke suction effect.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the present invention provides a range hood with a negative pressure chamber, comprising: a main body, a wind screen and a panel; the wind net is arranged at the lower part of the inclined surface of the main body; the panel is arranged at the upper part of the inclined plane of the main body and is connected with the wind net; the panel is provided with a negative pressure cavity, the negative pressure cavity is positioned in the main body, and an air inlet of the negative pressure cavity is communicated with the negative pressure hole in the panel.

In one or more embodiments, the outlet of the negative pressure chamber is inclined downward.

In one or more embodiments, a separation mesh is disposed within the negative pressure cavity.

In one or more embodiments, an oil receiving pan is connected to the bottom of the main body, and the oil receiving pan corresponds to the oil hole in the bottom of the main body.

In one or more embodiments, a safety net is disposed on the blower inside the main body.

In one or more embodiments, the panel is glass.

The utility model has the beneficial effects that: the range hood with the negative pressure cavity has a simple structure, and the panel is provided with the negative pressure cavity and the negative pressure holes to suck escaping oil smoke which is not sucked at the air net, so that a good oil smoke suction effect is achieved.

Detailed Description

The application scheme is further described below with reference to the accompanying drawings:

referring to fig. 1 to 3, the range hood with a negative pressure cavity of the present application includes a main body 10, a wind screen 11 and a panel 12; the wind screen 11 is arranged at the lower part of the inclined surface of the main body 10; the panel 12 is arranged on the upper part of the inclined plane of the main body 10 and is connected with the wind net 11; wherein, be equipped with negative pressure cavity 13 on the panel 12, negative pressure cavity 13 is located main part 10, and the air intake intercommunication negative pressure hole 121 on the panel 12 of negative pressure cavity 13.

When the range hood works, the fan in the main body 10 is started, so that oil smoke is sucked into the main body 10 through the air net 11 and then discharged to the outside, and the oil smoke which does not enter the air net 11 continuously escapes upwards, and when reaching the negative pressure hole 121, the oil smoke is sucked into the main body 10 through the negative pressure hole 121 and the negative pressure cavity 13 in sequence under the action of the fan.

Preferably, the air outlet of the negative pressure cavity 13 is inclined downward, so that the oil separated from the oil smoke slides down along the inclined surface.

Preferably, a separation net 14 is arranged in the negative pressure cavity 13, and the separation net 14 cools and separates the sucked oil smoke, so that only the smoke is discharged by the range hood.

Preferably, an oil receiving pan 15 is connected to the bottom of the main body 10, and the oil receiving pan 15 corresponds to an oil hole at the bottom of the main body 10. The oil separated from the oil smoke flows to the oil receiving pan 15 through the oil holes and is collected.

Preferably, a safety net 16 is provided on the blower inside the main body 10. The safety net 16 plays a role of protection.

Preferably, the panel 12 is made of glass, which is convenient for cleaning.

The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
