Powder smoke shielding and isolating device

Abstract

The invention relates to a fume dust shielding isolation device used for solving the problem of incomplete suction and exhaust of the fume dust during the using process of the household and commercial kitchen ranges in the prior art. The fume dust shielding isolation device comprises a stove head ring, a suction motor, an air channel pipe and is characterized in that an exhaust motor and an oxygen supplying pipeline are also arranged in the fume dust shielding isolation device; the air channel pipe comprises an outer air channel pipe and an inner air channel pipe; the suction motor is mounted on the air inlet of the outer air channel pipe; the air outlet of the outer air channel pipe is positioned above the stove head ring; the exhaust motor is mounted on the air outlet of the inner air channel pipe; the air inlet of the inner air channel pipe is positioned above the stove head ring; the outer air channel pipe is communicated with the stove head ring through the oxygen supplying pipe. The fume dust shielding isolation device has the advantages that the design is novel; the suction motor and the exhaust motor are mounted separately; the positive pressure air outlet can be inclined upwards or downwards or arranged horizontally; besides, an oxygen supplying pipe is arranged in the isolation device so that the fume dust suction effect of the isolation device is complete; meanwhile, the air pollution caused by the insufficient combustion is eliminated; the fume dust shielding isolation device is widely applicable to the various types of household and commercial fume dust suction and exhaust devices.

Description

Technical field: [0001] The invention relates to a powder and fume shielding and isolating device, which is used to solve the problem of incomplete suction and discharge of powder and fume when the existing household and commercial stoves are used. Background technique: [0002] With the development of society and the progress of civilization, consumers' awareness of energy conservation and environmental protection has been continuously enhanced, and their requirements for the quality of living environment have also been continuously improved. There are a large number of different sources of powder and dust pollution in people's living environment, which is harmful to human health. Especially the kitchens of urban houses today are mostly small confined spaces. When cooking, the smell of oily smoke is still strong, and the powder smoke is pervasive. The human body is very prone to anorexia, dizziness, fatigue and other consequences due to inhalation of a large amount of powde...

AI Technical Summary

Problems solved by technology

These existing dust shielding and isolation devices more or less have the following defects: 1. Air suction and exhaust are realized by the same blower fan, which is used to get rid of the air outlet of the air duct pipe of oil fume and the air intake for sucking air. The air inlets of the air duct pipes are connected, so that the dust and dust cannot be completely discharged during work, and a small part of the dust and dust will flow back to the air outlet of the air duct pipe used to inhale air, blowing into the pot, causing secondary pollution; 2 1. The direction of the air outlet of the air duct is either horizontal or downward, and the application occasions and scope are not wide enough; 3. The bottom exhaust range hood is also called deep well type gas appliance, and its combustion burner is installed deep at the bottom. When the pot is placed on the burner ring, the distance between the edge of the pot and the burner ring is very small. This design makes it equivalent to cooking at the bottom of a well when using this gas appliance, which may lead to insufficient oxygen supply during combustion. It is easy to cause incomplete combustion, and the carbon monoxide emission exceeds the standard, causing re-pollution to the kitchen environment
