Description

A kind of efficiently pure flat electricity combustion stove of retractable stand formula

Technical field

The present invention relates to electric power, combustion field, are a kind of efficient, gas-cooker (electric stove) structures of telescopic type.

Background technique

Gas-cooker is a kind of very universal household cookware, and the common thermal efficiency only has 60% or so, due to existing gas-cooker The limitation of structure has been difficult to improve efficiency of combustion；And the combustion gas of annual probably 370,000,000,000 cubes of the needs of China, and 40% needs Therefore import improves thermal efficiency of gas stove, can not only save 100,000,000,000 cubes of combustion gas every year, but also can reduce greenhouse Gas discharge, protects environment.

Currently, the gas-cooker that family uses, the mostly bicyclic or polycyclic flame in burning；The heat flow of flame of centre is general Only account for burner heat flow 10 ~ 20% or so (desk-top stove: 16 ~ 20% or so, embedded stove: 10 ~ 16% or so).Center is burning hot The size of flow is mainly limited by burner Means of Secondary Air Supplement；Central flame heat flow is excessive, and oxygen supply is insufficient, combustion The pernicious gas burnt in flue gas then may be exceeded.The heat flow of embedded gas range central flame is generally smaller than gas cooker, Mainly since the air supply of embedded gas range central flame is than gas cooker difficulty, to guarantee having in combustion product gases Evil gas is not exceeded, has to the heat flow for reducing central flame.

And the thermal efficiency of general coal-burning boiler is between 70%-90%, and the boiler thermal efficiency of large power plant can achieve 95%. Most of gas fired-boiler thermal efficiency could pass through national authentication at least more than 90%.Therefore, the thermal efficiency of gas-cooker, there is also very Big room for promotion.

By the structure of current gas-cooker, it is common that entered the wind using simple four sides, centre lacks air, 80% burning All occur in the outer ring of pot, and with the cold air on periphery strong heat exchange can occur for outer ring burning, and amount of heat is caused to be lost, Combustion thermal efficiency can not improve, and therefore, design reasonable structure, be the effective solution for improving thermal efficiency of gas stove.

For current gas-cooker due to combustion head, bracket is all to cause cleaning inconvenient on prominent hearth table top, have an effect on It is beautiful.

In order to fundamentally solve current gas stove existed general problem, the present invention uses completely new chamber structure, With scalable bracket, efficient pure flat gas-cooker is developed, is also applied for the kitchen tools such as electric ceramic heaters, plasma stove, present invention system Referred to as electricity combustion stove.

Summary of the invention

The object of the present invention is to provide a kind of high-efficiency gas stove of brand new (electricity combustion stoves), can effectively promote burning effect Rate, and easy to clean, good appearance.

A kind of efficiently pure flat electricity combustion stove of retractable stand formula, it is characterised in that combustion head is mounted on U-shaped semi-enclosed combustion Interior is burnt, and is not higher than hearth table top, forms pure flat structure；The pan bracket of annular cylinder shape overlays on combustion chamber along upper and pot one The space for constituting a relative closure is acted, the pan bracket outer diameter for reducing heat losses, improving combustion efficiency, and ring structure is rigid Well be less than U-shaped combustion chamber internal diameter, when cooking stove when not in use, can pan bracket be inverted put in the combustion chamber so that hearth be water It puts down without protrusion.

The present invention adopts the following technical solutions to realize.

A kind of efficiently pure flat electricity combustion stove of retractable stand formula, by the U-shaped combustion chamber being mounted on hearth face, bottom is provided with Air inlet hole, inside are equipped with combustion head, thereon along being inverted L shape, can be in close contact with ring cartridge type pan bracket and keep pot steady, in ring Along setting, there are three protrusions to support point on shape pan bracket, allows pot and pan bracket to form exhaust gap, using waste heat to the pot upper half Divide further heating, promotes combustion thermal efficiency.

Preferably, the U-shaped combustion chamber is round, rectangular or polygonized structure, and is made for heat insulating refractory material.

Preferably, lifting structure is rotated for screw-type between the U-shaped Inner Wall of Combustion Chamber and ring support outer wall.

Preferably, the U-shaped combustion chamber, ring support is by heat resistant fire-proof thermal insulation material, glass, ceramic making.

Preferably, the U-shaped bottom of combustion chamber air inlet hole is equipped with blast pipe, is attempted by kitchen ventilator exhaust outlet, allows useless Gas burns again, reduces discharge.

Specific embodiment

Principle according to the present invention, a kind of efficiently pure flat electricity combustion stove example of retractable stand formula are as follows:

Example 1

As shown in Fig. 1, a kind of efficiently pure flat electricity combustion stove of retractable stand formula, by ring support 1, hot plate 2, U-shaped combustion chamber 3, combustion head 6, air inlet pipe 8 and pedestal 7 are constituted, and are disposed with supporting point 4, in U-shaped combustion chamber 3 on the upper edge of ring support 1 Bottom is provided with ventilation hole 5, is connected to air inlet pipe 8.Along being inverted L shape on U-shaped combustion chamber, for being mounted on the cooktop surface for being provided with recess hole On plate 2, and lower than above hot plate, the lower edge of ring support 1 is L-type, for being placed on edge on U-shaped 3 inverted L shape of combustion chamber On, it is used to support pot, and form exhaust gas discharge slit there are three (or multiple) supporting point 4 along upper on ring support 1.

When gas-cooker normal combustion, air enters from the air inlet hole 5 of U-shaped bottom of combustion chamber, and exhaust gas after burning is from pot Gap discharge between the upper edge of ring support 1, and the process burnt carries out in the U-shaped bags of relative closure, Higher ignition temperature can be kept, makes burning more abundant, the thermal efficiency can promote 20%-30%；Due to U-shaped bottom of combustion chamber It is connected to air inlet pipe 8, air inlet pipe 8 kitchen ventilator exhaust outlet can be connected to, the exhaust gas containing oil smoke is burnt again, is further promoted Low exhaust gas emission drops in the thermal efficiency.

Example 2

As shown in Fig. 1, a kind of efficiently pure flat electricity combustion stove of retractable stand formula, by ring support 1, hot plate 2, U-shaped combustion chamber 3, combustion head 6, air inlet pipe 8 and pedestal 7 are constituted, and are disposed with supporting point 4, in U-shaped combustion chamber 3 on the upper edge of ring support 1 Bottom is provided with ventilation hole 5, is connected to air inlet pipe 8.There is a threaded connection in U-shaped 3 inner wall of combustion chamber and 1 outer wall of ring support, and can be with By rotary annular bracket 1,4 height of pot supporting point is increased or decreased, ring support 1 can also be contracted in U-shaped burning completely The inside of room 3 allows gas kitchen range panel holding level without protrusion.Other principles are identical as example 1.

The foregoing describe basic principles and main features of the invention and advantages of the present invention.The technical staff of the industry answers The understanding, the present invention is not limited to the above embodiments, and the above embodiments and description only describe of the invention former A kind of applicable cases of reason only change component structure, quantity, shape, material without departing from the principle of the present invention The parameters such as matter, mounting means, size, these changes and improvements belong to the scope of the present invention.
