Technical Field

The invention relates to a gas cooker, in particular to a gas plug valve and a gas inlet pipe for a flat gas cooker.

Background

The flat gas stove is a gas stove with a new structure developed in recent years, and is popular with consumers because the flat gas stove is thin and does not need to be provided with a large mounting hole on the table top of a cabinet like an embedded gas stove.

The existing flat gas stove has the advantages that the thickness of the flat gas stove is thin, and except that the upward protruding height of a valve core part exceeds 20mm, the heights of other parts do not exceed 20 mm. Because the restriction of flat gas-cooker thickness and plug valve structure can't adopt the gas intake pipe of traditional structure, need replace traditional structure gas intake pipe with two 6 ~ 8 millimeters external diameter metal pipes and a tee bend gas air inlet joint, at gas plug valve air inlet end and tee bend gas air inlet joint department, all need set up screwed joint and connect this metal pipe. With this structure, there are several disadvantages as follows: 1. the metal pipe of the traditional air inlet pipe is replaced, the routing is long, the bending is more, the attractiveness is affected, and the flowing loss of the fuel gas in the pipe is increased due to the long routing and the bending; 2. the number of pipeline connection points is large, so that potential safety hazard points of gas leakage are increased, and 3, the material cost and the assembly cost are increased. For a flat gas stove at a high price, will not cause discomfort in the mind of a consumer when the panel is removed and the internal structure is more "disorderly" than that of a common embedded gas stove? This is worth thinking and attention of manufacturers.

The existing flat gas plug valve is only provided with two gas channels which are respectively communicated with an outer ring fire and a central fire nozzle of a burner, and cannot meet the requirements of a three-ring fire burner which needs to control an outer ring fire, a middle ring fire and a central fire respectively, so that the development of a flat gas stove is limited.

Although the existing gas plug valve also has a three-channel plug valve which can respectively control the outer ring fire, the middle ring fire and the central fire of a burner, the height of the plug valve main body can not meet the requirements of a flat gas stove. In addition, the existing three-channel plug valve cannot realize the functions of the two-channel plug valve in a simpler mode, and if the three-channel plug valve can be realized, the investment of a plug valve manufacturing mold and the management and control of materials can be reduced, and the application of the plug valve is facilitated.
