Abstract

The utility model discloses a safety gas radiator using liquefied gas as fuel. A burner (2) and an igniter (7) are arranged on the bottom of a casing (1); the upper part of the burner (2) is provided with a combustion chamber composed of a straight-through metallic cylinder (4) and the burner (2); the top of the metal cylinder (4) of the combustion chamber is provided with a heat exchanger (6) which is itinerantly penetrated in a heat collector (5) and continuously wound and fixed on the outside of the metal cylinder (4) from top to bottom and a flameout, overheat, room temperature control mechanism which is composed of a thermocouple, a thermistor, a digital display thermometer, a controller and a gas valve. The utility model has the advantages of reasonable structure, high efficiency, low consumption, sanitation and convenience, convenient operation, adjustable room temperature control, no pollution, etc.

Description

Safety gas radiator

The utility model relates to a kind of small-sized heating boiler, particularly relates to a kind of heating boiler that make use of liquefied petroleum gas and act as a fuel.

Northern China is colder winter, and in the cities and towns of some no central heating, cottar's dwelling house, hotel, restaurant etc., general " the native heating installation " or small scall coal-fired boiler or the stove of lighting a fire of adopting is warmed oneself.No matter above-mentioned which kind of heating mode all will expend a large amount of coals, not only time-consuming, bothersome, unhygienic but also room temperature is low, uncontrollable, air and environment easily pollute, and do not note slightly, just the gas poisoning phenomenon may take place, and weight person will cause death.

The purpose of this utility model is will provide a kind of to replace coal with liquefied gas, both saved time save trouble, clean hygiene, can improve and also control room temperature selectively, no air and environmental pollution, do not jeopardize the safety fuel gas house heater of people's life safety.

Task of the present utility model realizes as follows:

This utility model comprises cabinet, burner, heat exchanger, igniter, heat collector and controller, the utility model is provided with burner and igniter in the cabinet bottom, directly over burner, be covered with a through type metal cylinder and burner and constitute the combustion chamber, on the heat collector on the metal cylinder top of combustion chamber, be provided with the touring tubular heat exchange that then is fastened continuously again in the heat collector metal cylinder outside that is installed on from top to bottom and reach flame-out, overheated, the room temperature controlling organization of forming by thermocouple, thermistor, digital display temperature meter, controller, gas valve.

The utility model is owing to change fire coal into combustion gas, and whole organic cooperation of controlling organization in addition makes this utility model have rational in infrastructure, efficient low-consume, convenient and healthy, easy and simple to handle, and room temperature is controlled adjustable advantage such as pollution-free.Especially can avoid combustion gas excessive in combustion process, anhydrous empty burning and accident extinguishing in particular cases can make gas valve close automatically in heat exchanger, guarantee the safe and reliable of work.

Accompanying drawings embodiment:

Fig. 1 is the complete machine structure schematic diagram of safety fuel gas house heater.

As shown in Figure 1, that cabinet of the present utility model 1 bottom is provided with is main, pay the deep hole cross-tube burner 2 that two burners are formed, by the card of cabinet 1 bottom with its support fixation.Control by gas valve 3 between this burner 2 and the air inlet pipe.Burner 2 constitutes the combustion chamber with the metal cylinder 4 that covers on above it, the top of combustion chamber is the heat collector 5 that is made of dozens of sheet metal with holes, the water inlet pipe of heat exchanger 6 is fastened on metal cylinder 4 outer walls from bottom to top through water intaking valve 8, and goes the rounds continuously to pass from heat collector 5.The air inlet pipe of the water inlet pipe of heat exchanger 6, outlet pipe and burner 2 is respectively by drawing in the hole on cabinet 1 sidewall, fixing by taper pipe thread and cabinet 1, and with water supply valve (or water pump), radiator (radiator just) and liquefied gas tube connector join accordingly.Excessive for preventing combustion gas, be provided with thermocouple in burner 2 tongues of fire positions, this thermocouple is transferred to controller with signal, and the self-priming magnetic valve in the controller control gas valve 3 is to realize the start or stop of gas valve 3.Also lay a thermistor on the sidewall of combustion chamber metal cylinder 4, thermistor still is connected with controller and controls gas valve 3 and water intaking valve 8 by controller.Be provided with steam vent and connect blast pipe outdoor unnecessary micro-waste gas and hot gas discharge on the top of cabinet 1.

During use, open water intaking valve 8 earlier, and connect gas valve 3, press press button fixing on the cabinet 1 front housing then, corresponding indicator lamp is bright, and ignition 7 is lighted burner 2 by spray point, and this moment, house heater was started working.Room temperature raises gradually with water temperature, it is indoor when anhydrous empty the burning is housed in temperature that digital display temperature meter and access controller select control when room temperature is higher than or the heat exchanger 6, the resistance of thermistor changes, automatic self-closing gas valve 3 and water intaking valve 8(or water pump under the effect of controller), only keep a kindling material.When room temperature is lower than selection control temperature, gas valve 3 and water intaking valve 8(or water pump) just to open automatically, burner 2 burns away.When stopping working when meeting accident, the thermocouple on the burner 2 turn-offs gas valve 3 fast and enters valve 8(or water pump by controller), in case combustion gas is excessive, avoid having an accident.The utility model is widely used in town and country does not have the home dwelling of central heating, hotel, restaurant, school, and other places such as dormitory of field work.

Claims

1, a kind of safety fuel gas house heater, comprise cabinet (1), burner (2), heat exchanger (6), igniter (7), heat collector (5) and controller is characterized in that cabinet (1) bottom is provided with burner (2) and igniter (7), directly over burner (2), be covered with a through type metal cylinder (4) and burner (2) and constitute the combustion chamber, on the heat collector (5) on metal cylinder (4) top of combustion chamber, be provided with the touring tubular heat exchange (6) that then is fastened continuously again in the heat collector (5) metal cylinder (4) outside that is installed on from top to bottom and reach by thermocouple, thermistor, digital display temperature meter, controller, it is flame-out that gas valve (3) is formed, overheated, the room temperature controlling organization.
