Abstract
The utility model discloses a gas heater prevents frostbite, include: the casing sets up air intake, outlet flue on the casing to and combustor, the heat exchanger of setting in the casing, air intake and room air intercommunication, outlet flue and outdoor intercommunication, a serial communication port, each junction of casing is all sealed by sealed the pad, is equipped with movable closing plate on the air intake, the closing plate is opened under the drive arrangement effect, closed air intake. The utility model provides a pair of though gas heater prevents frostbite installs in indoor, be same pressure field with the external world, can not produce the downdraught, also effectively avoid gas heater to prevent downdraught device inefficacy problem under abominable service environment. Simultaneously, need not to set up special supporting tobacco pipe like balanced type gas heater, the exhaust pipe diameter does not change, and mounting structure is simple.
Description
Technical field
The utility model relates to fluid heater technical field, particularly relates to a kind of anti-freezing gas water heater.
Background technology
At northern area, when winter environment temperature is lower than zero degree, if gas heater quits work, by the impact of water heater housing inner and outer air pressure difference, cold outdoor air is very easily poured in down a chimney to gas heater inner, causes ducted coolant-temperature gage to continue to be reduced to subzero, and water freezes when subzero, volumetric expansion causes pipeline breaking, and leakage accident occurs.
At present, means to prevent freezing general in industry is for preventing downdraught and Electric heating, and Electric heating easily limits by heating power, and preventing air reverse flow mainly ends at exhaust opening, easily loses efficacy by the impact of environment for use (as oil pollution environment).
In prior art, though balance type gas water heater can form a sealing system of isolating with room air together with supporting flue, avoid pouring in down a chimney of cold outdoor air.But cause smoke discharging pipe large because air inlet/outlet is all taken at outdoor, difficulty is installed, affects attractive in appearance simultaneously.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide the anti-freezing gas water heater that a kind of mounting structure is simple, avoid cold wind to pour in down a chimney.
For reaching above object, the utility model adopts following technical scheme.
A kind of anti-freezing gas water heater, comprising: housing, is arranged on the air inlet on housing, outlet flue, and be arranged on burner, the heat exchanger in housing; Described air inlet and ambient air, described outlet flue is communicated with outdoor; It is characterized in that, each junction of described housing is all sealed by sealing gasket, air inlet is provided with movable sealing plate, described sealing plate is opened under drive unit effect, closes air inlet.
Further illustrating as such scheme, in air inlet week along being provided with the sealing gasket contacted with air intake plate.
Further illustrating as such scheme, described drive unit is that stepper motor, magnetic valve or cylinder etc. can be subjected to displacement drive unit.
Further illustrating as such scheme, the outlet flue of housing is provided with sealing ring.
Further illustrating as such scheme, air inlet or outlet flue are provided with air blast.
Further illustrating as such scheme, is provided with hygrosensor and electric heating body on heat exchangers, and a controller is connected with hygrosensor and electric heating body signal, and the temperature information according to hygrosensor feedback controls electric heating body work.
Compared with prior art, a kind of anti-freezing gas water heater that the utility model provides has following beneficial effect:
One, Yin Putong wind-proof device can lose efficacy in severe environment for use, as guide rod cannot cut out or frozenly under the state having steam cannot to open by greasy dirt is stuck, and the generation of downdraught is because water heater is installed on indoor, the pressure field of water heater inside is identical with indoor, indoor generation pressure reduction different from pressure outside and form downdraught.The utility model passes through housing seal, and arranges sealing plate on air inlet, makes it airtight when not using, although be installed on indoor, but be same pressure field with the external world, can not downdraught be produced, also effectively avoid gas heater backward flow preventing device Problem of Failure under severe environment for use.Meanwhile, without the need to arranging special supporting smoke pipe as balance type gas water heater, smoke discharging pipe diameter does not change, and mounting structure is simple.
Two, after preventing cold air from pouring in down a chimney, electric heater unit is little, more energy-conservation with the electric heater unit phase specific power used at present.

Detailed description of the invention
Understand essence of the present utility model better for convenience of those skilled in the art, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1 and Figure 2, a kind of anti-freezing gas water heater, comprising: housing 1, is arranged on the air inlet 2 on housing 1, outlet flue 3, and is arranged on burner 4, the heat exchanger 5 in housing 1; Described air inlet 2 and ambient air, described outlet flue 3 is communicated with outdoor; It is characterized in that, each junction of described housing 1 is all sealed by sealing gasket 6, and air inlet 2 is provided with movable sealing plate 7, and described sealing plate 7 is opened under drive unit 8 acts on, closed air inlet 2.
In the present embodiment, within 2 weeks, along being also provided with the sealing gasket 9 contacted with air intake plate 7, preferred drive unit 8 is stepper motor to preferred air inlet.For ensureing air inlet effect, preferably on outlet flue 3, be also provided with air blast 10.In other embodiments, described drive unit changes magnetic valve (namely utilizing magnetic and spring to control the opening and closing of air intake plate) or cylinder into, and described air blast changes and is located at air inlet, is not limited to the present embodiment.
As shown in Figure 3, for improving the sealing property of housing 1, the outlet flue 3 of housing is provided with sealing ring 11.
During practical application, air inlet 2 is arranged to normally off, and during gas water heater working, air inlet 2 is opened, and room air participates in burning.When gas heater quits work, air inlet 2 is closed, and then avoids the gas in housing 1 and open-air convection current, effectively avoids cold wind to pour in down a chimney in housing 1, good freezing protection effect.
For improving the resistance to frost of gas heater further, heat exchanger 5 is also provided with hygrosensor 12 and electric heating body 13, one controller 14 is connected with hygrosensor 12 and electric heating body 13 signal, and works according to the temperature information control electric heating body 13 that hygrosensor 12 feeds back.Specific works principle is: when the temperature of water in heat exchanger starts heating lower than electric heating body 13 during certain design temperature, after the temperature of water in heat exchanger reaches another design temperature, electric heating body 13 stops heating.
Above detailed description of the invention has been described in detail essence of the present utility model, but can not limit protection domain of the present utility model with this.Apparently, under the enlightenment of the utility model essence, the art those of ordinary skill also can carry out many improvement and modification, it should be noted that these improve and modify and all drops within claims of the present utility model.
