Description

Household gas range is protected gas ket

Affiliated technical field

The utility model relates to a kind of guarantor's gas ket that is common to coal gas, liquefied petroleum gas, natural gas household gas range, especially a kind of heat that can intercept is distributed the raising thermal efficiency, not only Bao Re but also the non-conducting heat raising thermal efficiency, the flame that can raise improves the thermal efficiency, and the too fast speed of the hot-fluid that can slow down improves the thermal efficiency, can improve the thermal efficiency by corresponding minimizing combustion-supporting air quantity, combustion gas is fully burnt under the condition of high temperature improve the thermal efficiency, waste gas is few, and is energy-conservation, is convenient to observe guarantor's gas ket of flame.

Background technology

At present, known household gas range opens wide burning, needs the burning of maximum airflow source of the gas usually, and it is many to exist heat to distribute, and waste gas is many, the problem of big energy-consuming; The rate of heat flow in the bottom of a pan is too fast again, has the many problems of heat of taking away.

The utility model content

To open wide the thermal efficiency that burning exists low in order to solve present household gas range, waste gas is many, the too fast many problems of heat of taking away of big energy-consuming and rate of heat flow, the utility model proposes on a kind of range panel that is placed in household gas range, be trapped among the flame periphery, be not only applicable to coal gas, liquefied petroleum gas, natural air-air source gas-cooker, and can be according to above-mentioned source of the gas burning maximum heat flow that discharges and the amount of space that uses required source of the gas burning, control flame cross-sectional area rising flame increases the pot endotherm area and improves the thermal efficiency; Can intercept heat and distribute the raising thermal efficiency; Can protect hot non-conducting heat and improve the thermal efficiency; Can regulate the fuel gas buring amount of space according to the source of the gas required amount of space that burns, combustion gas is fully burnt, improve the thermal efficiency; Reduce waste gas; Can protect heat and make combustion gas fully burning under the condition of high temperature, energy-conservation, thermal efficiency height, guarantor's gas ket that waste gas is few.

The technical scheme that the utility model technical solution problem is adopted is: protect gas ket and mainly be made up of guarantor's gas ket body, inner ring, outer ring, a pot plate, support.Described guarantor's gas ket body is manufactured the circle of the truncated cone that big end makes progress by flame-proof thermal insulation material, protect gas ket intracoelomic cavity and inner ring and all be provided with five road flame control circles, the convex R of five road flame control circles separately is tangent line altogether, all is provided with cylindrical gas combustion chamber and the flat circle face that increases one by one from top to bottom between flame control circle; Inner ring is fixed on to be protected in the gas ket body, and the outer ring is set as the shape of protecting the gas ket body profile, is fixed on that to protect gas ket external, and the outer ring does not connect inner ring; 5 pot plates are set as the polygon plate of congruent shape, and the middle part is provided with a circular hole, and each limit to circular hole pitch-row does not wait, equipped socket cap rivet in the circular hole, and five pot plates are riveted on respectively on the upper surface of inner ring; Support is made up of five vertical rods and a round iron circle, and vertical rod upper end is fixed on the outer ring, and the lower end respectively is welded on the position of five five equilibriums of round iron circle, the screw of the equipped axial adjustment in vertical rod lower surface.

The utility model adopts above-mentioned technology beneficial effect to be:

Because be provided with the gas combustion chamber that increases one by one from top to bottom between the flame control circle of inner ring and guarantor's gas ket body, coal gas, liquefied petroleum gas, natural gas all have clean-burning space, combustion gas can fully be burnt, thermal efficiency height, and waste gas is few;

Because 5 pot plates are set as the polygonal shape of congruence and the plate that does not wait to its middle part circular hole pitch-row on each limit, can determine a limit that the pot plate props up pot according to the maximum airflow that fuel gas buring discharges, just can be according to using required heat flow, regulate the fuel gas flow amount, rotate a pot plate and select a limit of pot, control flame cross-sectional area, rising flame, increase the endotherm area of pot, thermal efficiency height, energy-conservation;

Because the guarantor's gas ket body that is trapped among the flame periphery is made by flame-proof thermal insulation material, not only intercepted heat and distributed but also be incubated, and combustion gas under the condition of high temperature, burn more abundant, thermal efficiency height, waste gas is few;

Because inner ring does not connect the outer ring, there is not the heat conduction between them, thermal efficiency height;

All be total to tangent line separately owing to protect the convex R of gas ket body and inner ring flame control circle, be convenient to observe flame;

Because it is cylindrical that the combustion chamber is set as, the hot-fluid that enters the fuel gas buring formation of combustion chamber makes progress the rising cooking bottom temperature along the periphery direction; The main flow direction of this direction of heat flow and the bottom of a pan hot-fluid constitutes angle again, the too fast rate of heat flow that slows down, and cooking bottom temperature is higher relatively; Corresponding therewith combustion-supporting air quantity also reduces, and cooking bottom temperature is higher.

Be set as flat circle face owing to protect the gas ket inner bottom surface, intercept heat and distribute, avoid range panel not to be heated;

As seen from above-mentioned, this guarantor's gas ket is applicable to coal gas, liquefied petroleum gas, natural air-air source household gas range, and is energy-conservation, thermal efficiency height, and waste gas is few, and is convenient to observe flame, and practical function is very positive.
