Abstract

A cooking utensil consists of a cabinet, a range (10) and a smoke exhaust ventilator. Front and rear vertical suction ports (100) both are disposed on the smoke exhaust ventilator, and an inclined retarding wall (30) and a horizontal hood (20) arranged on the same. In the smoke exhaust ventilator, the distance for smoke exhausting is shorter, and in use a shielding space held by two different envelope surfaces is formed. There is a large effective free space in this exhaust ventilator with two envelope surfaces and short exhausting distance which exhausts smoke downwards. At the same time, the problem of flow backwards of polluted air in flue is solved in the cooking utensil.

Description

Oil exhaust smoke cooker

The invention relates to the field of mechanical devices, and in particular to an oil exhausting smoke cooker equipped with a double envelope surface near-down air exhaust device. Background technique

At present, the well-known exhaust gas exhaust device consisting of a fan, an air suction duct, an air suction port and an exhaust air duct can be classified into a top suction and a side suction according to the position of the air suction port. The side suction type exhaust fume device can be divided into one-way side suction and ring side suction according to the form of the suction port.

We call the space around the cooktop for cooking use a free and effective space. From the convenience of the work, there should be a larger value. The distance from the suction port of the exhaust fume device to the pollution source - the plane on which the upper edge of the cooking pot is located (hereinafter referred to as the contaminated surface of the cooker) is called the effective range of the range of soot; the negative rate of soot absorption is related to the distance. of. From the point of view of the fume removal rate, there should be a small value.

The top suction type fume device is arranged on the top of the contaminated surface of the cooker because of its suction port. Considering the free effective space, the suction port is passively set to a far distance from the contaminated surface of the cooker, that is, it has a large distance of the oil fume. This results in a lower soot removal rate for the soot unit.

The side suction type fume extracting device usually has a high soot absorption rate because the suction port is actively set at a relatively close distance from the contaminated surface of the cooker, that is, it has a small effective range of the soot. For the top suction type fume device, the effective range of the soot is generally larger than that of the ring side fume device, that is, the fume removal rate has a lower value. For a ring side suction fume device, the free effective space usually has a small value; in other words, the fume device is characterized by its entanglement as a defect. For example, an existing type of oil-discharge stove has been placed in the so-called "deep well", and the cooking pot is smashed against the wall. Summary of the invention

In order to overcome the various deficiencies of the existing exhaust fume device, including the exhaust fume cooker, the present invention An exhaust gas cooker is provided. The device is provided with two vertical suction vents at the same time, and is provided with a slanted blocking wall and a horizontal hood, which has a small effective range of oil absorbing fumes, especially formed in the work by two different envelopes. The shielding space overcomes the defects of the lower soot absorption rate of the top suction type and the ordinary one-way side suction type fume exhaust device; and has a large free effective space, thereby overcoming the operation of the ring side exhaust fume device. defect. Incidentally, the present invention completely solves the problem of backflow of the flue-contaminated gas of the conventional exhaust lamp device.

The technical solution adopted by the present invention to solve the technical problem is that the exhaust gas cooker of the present invention is composed of a cabinet, a cooker and a fume exhausting device, the cooker and the fume extracting device are embedded in the cabinet, and the fume extracting device is in the cooker The back.
