Abstract
The utility model relates to a gas boiler provided with an anti-freezing electric-heating device, comprising a water jacket and a controller. An electric heater and a temperature controller connected with the electric heater are arranged in the water jacket. The electric-heating device and the temperature controller additionally arranged on the utility model can realize a heating start when the water temperature in the boiler is slightly under the gas anti-freezing temperature point, effectively avoid the frozen and damage to boilers in case of the failure of the gas anti-freezing device and guarantee a normal running of boilers in a serious cold district.
Description
Technical field
The utility model relates to a kind of hot-water boiler, particularly a kind of gas fired-boiler that has antifreeze electric calorifie installation.
Background technology
The utility model discloses a kind of " the bath stove is warmed up in the normal pressure combustion gas " in the patent No. is the utility model patent of ZL (patent No.), solved existing boiler function singleness, heat effectively and imitated low and have the problem of potential safety hazard.And also be provided with the automatic freezing-protective device, when water temperature is lower than setting value (as 5 ℃), its controller can be opened gas valve and ignition combustion device automatically, and can cut off source of the gas when being higher than a certain temperature (as 15 ℃).This function can prevent boiler frozen or phenomenon of being damaged by frost when out of service effectively at severe cold area.But in long-term use, find, under individual other situation,,, cause freezing in the boiler even damaging at antifreeze function startup afterburner loss of ignition owing to a variety of causes (thoroughly ice stifledly cause stopping the supple of gas or steam etc. as burning line internal cause dehydration).
Summary of the invention
The purpose of this utility model just provides a kind of gas fired-boiler that has antifreeze electric calorifie installation that prevents the frozen damage of boiler after the combustion gas defroster lost efficacy.
The technical solution of the utility model is: comprise water leg and controller, be provided with electric heater and connected thermostat in described water leg.
Described electric heater is an electrical bar, and described thermostat and controller are integrated.
Also comprise the water pump that is connected on the water supply loop that is connected with described water leg.
Electric heating of setting up of the present utility model and temperature regulating device, water temperature that can be in boiler starts heating during a little less than the antifreeze temperature spot of combustion gas, prevented that effectively the boiler that caused after the combustion gas defroster lost efficacy from freezing or damage, and guaranteed the normal operation of severe cold area boiler.
Description of drawings
Fig. 1 is a lateral plan of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises shell 14, body of heater 9, and body of heater 9 is positioned at shell 14, and burner 10 is arranged below body of heater 9, and it is connected with an end of motor-driven valve 4 by tracheae 11, and the other end passes shell 14 and is used to connect fuel gas source.In body of heater 9, have vertical flue 15 under lead to the top, exhaust fume collecting hood 7 is arranged at the top, exhaust fume collecting hood 7 is connected with blower fan 6.Water leg (layer) 16 is arranged between each flue 15, have heating delivery port 2 and water return outlet 1 to be communicated with, a series connection water circulating pump 5 (former circulating pump is external) on the heating loop with water leg 16.For bathing and domestic water are provided, also in water leg 16, be provided with snakelike conduit 17, its two ends (12,13) pass body of heater 9 outer being connected on the shell.In water leg 16, be provided with temperature-sensitive element and be connected (not shown) with controller.It below all is the prior art part.Feature of the present utility model is to be provided with electric heater 8 and thermostat in water leg 16, and thermostat merges in original controller.Electric heater 8 can adopt electrical bar to insert in the water leg 16, and its low warm spot is arranged on and omits the end in the antifreeze temperature spot of combustion gas.Generally the former is 3 ℃, and the latter is 5 ℃.As long as the combustion gas defroster works, electric heater 8 just can not start like this.
Claims (3)
