The utility model has the obvious advantages that the combustion of utility model is windproof, combustion is complete, thermal efficiency is higher than 70%, the temperature rise of the stove end is fast, the ability of thermal load is strong, fuel is saved, cooking time is shortened, the cleanness of pots can be kept, and the environment of habitable rooms can be improved.

Description

Parabola heat build-up radiation gas-liquid fuels stove and accessory

The utility model relates to the stove and accessory of a kind of combustion gas or combustion liquid

The furnace combustor of Xiao Shouing adopts the naked light combustion system mostly in the market, the outside scattering of flame during burning, heat is except that a part is absorbed by pot, quite a few is space heat elimination and taken away by air-flow towards periphery, particularly when wind is moving, thermal loss is bigger, measure through relevant department, much adopt the thermal efficiency of the stove and accessory of naked light burning to have only 55-65%, and at the bottom of the very easy burning black-cooking pot of flame that burnt of the stove and accessory of naked light burning, in order to improve the thermal efficiency of stove and accessory, make fuel combustion complete, people have taked some measures, as increase windproof Tan, adjust air capacity etc., but can't tackle the problem at its root.

The purpose of this utility model provides a kind of flameless combustion and heat build-up radiation, and fuel can fully burn, and does not produce black smoke, and can significantly improve the gas-liquid fuels stove and accessory of the thermal efficiency.

The utility model is realized in following mode: on the burner position of existing stove and accessory, infrared ray burning radiation device in the repacking, between limit, radiator outer and stove and accessory panel, install the parabolic type heat build-up Radiation Cup of a shape such as flashlight optically focused reflector structure again, have vent and weeper on the Radiation Cup, infrared radiator exterior face and Radiation Cup outside are all with asbestos or other adiabator layer parcel.

The heat build-up surface of above-mentioned parabolic type heat build-up Radiation Cup can be: parabolic type or other mix profiles for how much and constitute, and can be that fix or movable, its objective is to make centralized heat energy and reflex to the bottom of a pan and easy to clean, improve the thermal efficiency of stove and accessory.

Above-mentioned infrared radiator can match with existing gas furnace with parabolic type heat build-up Radiation Cup, the method of transforming is: original burning jamb is pulled down, load onto infrared burner and parabolic type heat build-up Radiation Cup, and will get final product work in the fuel injector on the insertion of the nozzle on the former stove and accessory switch infrared radiator.

If when needing while using gases fuel and liquid fuel, its structure is that fuel inlet tube connects a fuel recycle heat air liquid/gas separator in stove and accessory, separator picks out one section outer heat air pipe and extends on the burner and heat, connect heating tube in a section again in the heating and gasifying pipe outside, the other end of interior heating tube was received on the switch after connecting gas-liquid separator inside, the course of work of this gas liquid two purpose stove and accessory is: when opening the fuel steel cylinder angle valve, owing in the bottle certain air pressure is arranged, liquid fuel is pressed stove and accessory, fuel enters separator from the stove and accessory inlet tube and isolates the gaseous fuel flow path and add hot vapor lamp, interior heating tube arrives switch, injecting injector by nozzle enters on infrared radiator inner chamber and the last burning web of string, light radiator with kindling material, burn the outer heat air pipe of heat, heating tube in allowing the fuel that has been heated turn back to flow into, and pass gas-liquid separator inside along interior heating tube stream, liquid fuel with heat transferred separator inside, impel the fuel speed up gas and liquid to transform, play the effect of circulation heating and gasifying fuel, the infrared radiator that burns combustion then is placed in the round parabolic type heat build-up Radiation Cup, and the heat that infrared radiator is sent is concentrated and is radiated on the bottom of a pan.

The utility model has the advantages that

1. thermal efficiency height, the heat energy utilization in the time of can be with fuel combustion more than 70%.Under equal conditions than existing stove and accessory fuel saving 25-35%.

2. parabolic type heat build-up Radiation Cup is with after infrared radiator combines, burner quick heating, temperature height, temperature stabilization, can be windproof, and the thermic load ability is strong, has shortened the cooking time effectively and has improved living environment.

3. fuel combustion is complete, and the bottom of a pan can not burnt black, and the bottom of a pan heating surface area is big and temperature is even.

4. the gas liquid two purpose stove and accessory is easy and simple to handle reliable, adapts to gaseous fuel and gas-liquid mixed fuel firing, and gas-liquid separation is rapid.

5. basic identical with existing gas furnace structure, as long as furnace head burner is changed this infrared radiator and parabolic type heat build-up Radiation Cup, switch and panel all need not be changed, can adapt to existing stove and accessory repair shop and reequip or establish special factory and produce supporting part in addition, take the marketing method of exchanging old for new special-purpose shop and consumer.

Below in conjunction with accompanying drawing enforcement structure of the present utility model is described.

Fig. 1 is that parabola heat build-up Radiation Cup combines the structure chart that forms burner with infrared radiator.

Fig. 2 is the gas furnace structure chart.

Fig. 3 is the structure chart of gas liquid two purpose stove and accessory.

See from Fig. 1, parabolic type heat build-up Radiation Cup 2 is housed in the burner 1, have vent 3 and weeper 7 on the Radiation Cup, in the centre of Radiation Cup is infrared radiator 5, the radiator top is an infrared radiation net 6, inner chamber at radiator 5 has fuel injector 4, and the outer wrap of Radiation Cup 2 and radiator 5 insulating 8.

See that from Fig. 2 gaseous fuel inlet tube 11 leads to switch assembly 10 earlier, by nozzle 12, enter radiator then from fuel injector 4, the 9th, stove and accessory shell and panel, method of operating is the same with existing gas furnace.

See from Fig. 3, fuel enters circulation heat air liquid/gas separator 13 by inlet tube 11, carry out gas-liquid separation, the gaseous fuel flow path that has separated adds hot vapor lamp 14, break joint between the interior heating tube 15 turns back and flows in the interior heating tube 15, and cross gas-liquid separator 13 along interior heating tube 15 percolations and arrive switch assemblies 10 inside, fuel is injected fuel injector 4 through switch assembly control flow by nozzle 12, and bring air into and be mixed into the radiator inner chamber, on the string radiation online, use the kindling material pilot fuel, radiator after lighting burns the outer heating tube 14 of heat, with fuel heating and by interior heating tube 15, transmit the liquid fuel of heat to the separator 13, impel gas-liquid to transform.
