Abstract

The invention provides a ventilation tower-type lower air-inlet gas cooker belonging to the field of gas cooker. The technical proposal different from the prior art comprises an up-down through hyperbolic guide flow cylinder (1); the lower end port of the hyperbolic guide flow cylinder is provided with a hearth (2) with a ventilation tower-type structure; and the hearth is internally provided with a burner. When the gas combusts in the hearth, the temperature of the fire in the hearth is much higher than the temperature of the air outside the hearth; a chimney effect is generated under the effect of hot pressure; the secondary air is sucked in from the lower end port of the hearth, is then combusted and exhausted out from the upper end port of the hearth; the hearth has a function of gathering fire and drawing fire; an external mixing chamber (3) and an internal mixing chamber (4) of the burner are structures of small cross-section and long cylinder body, and generate small resistance to the secondary air flowing from bottom to top; simultaneously, the mixed gas is heated for a long time by the hot mixing chamber cylinder and the temperature thereof is increased quickly so that the combustion is more sufficient and fierce. The gas cooker can reinforce the combustion and improve the heat gathering effect without increasing the external power.

Description

(1) Technical field

[0001] The invention relates to a ventilation tower type bottom-intake gas stove used in the field of gas combustion used in families, hotels, restaurants and catering industries. (2) Background technology

[0002] In recent years, people pay more and more attention to energy-saving and environment-friendly gas stoves. Improving the combustion efficiency and heat utilization rate of gas stoves and reducing the emission of harmful substances are the first issues to be considered in the design of gas stoves.

[0003] Generally, the structural feature of household gas stoves is that the volume of the burner is too large. According to its installation method, it can be roughly divided into two types. One is a desktop gas stove, which is directly placed on the cabinet table; the other is an embedded gas stove. The stove is installed in the reserved opening of the countertop of the cabinet. All there is following deficiency in above two kinds of gas ranges: th...
