Abstract
The invention provides an anti-freezing device of a gas water heater and relates to a reliable anti-freezing device capable of effectively preventing the cold air from entering the gas water heater and causing frost crack of an internal water pipe. The technical problems to be solved are as follows: 1. changing the traditional electric heating anti-freezing method which cause energy waste; 2.changing the method of windproof cap, which is only good in windproof function but poor in anti-freezing function; and 3. changing the method which needs such complex operations as pressure release and drainage after use every time. According to the technical scheme, a traction magnet, a connecting rod and a gravity sealing body in an air sealing cylinder body are connected in sequence; the magnet and the gas water heater are installed on the same controllable power supply; and the anti-freezing device is started by one key and closed by one key. The device mainly has the advantages of solving the general frost crack problem of the gas water heater in north in winter, and the anti-freezing measure is simple, energy-saving, safe, reliable and convenient in operation.
Description
A kind of gas heater defroster.Be linked in sequence by tractive magnet, lever, envelope air cylinder.Electromagnet is installed on the same base plate with the envelope inflator.Lower interface vertically inserts in the middle of the smoke evacuation tube of gas heater on the envelope inflator.
Affiliated field:
The present invention relates to a kind of cold air that prevents and get into the reliable defroster that gas heater causes the inner water tube bursting by freezing.
Know altogether that at present means to prevent freezing is
1, electric heater unit is installed in water heater, is controlled at 6 ℃ of-20 ℃ of scopes to the cold air temperature that blows back into water heater.Promptly be lower than 6 ℃ of heating, be higher than 20 ℃ and stop.
2, install anti-blast cap additional.
3, water in manually step-down, the emptying water heater
Summary of the invention:
The deficiency of existing antifreezing measures:
A, electrical heating: manufacturer is directly installed on heating resistor in the water heater, and water heater communicates with outdoor through very short smoke exhaust pipe, and every heating is once cool soon, because of being tired of heating power consumption every day 4-5 degree frequently, wastes very much electric energy.If winter unexpected power failure several hrs, water heater still can bursting by freezing.
B, anti-blast cap: open because of the cap body leans on the water heater pressure at expulsion, cause the cap body too light, poorly sealed, can only reduce cold air and flow into, can not solve anti-bursting by freezing problem.
C, step-down discharge water: complicated operation, in case forget the inevitable bursting by freezing of operation water heater.
The invention provides a kind of novel defroster; When using, can open immediately by this defroster; Reliably close immediately after the use; Guarantee that outdoor cold air can't get in the water heater, fundamentally solved the water heater bursting by freezing problem that prevents, again special power saving and simple to operate safe and reliable, only need press twice power switch (opens, and stops) before and after using water heater.Even if having a power failure suddenly for a long time, water heater can bursting by freezing yet.
The technical solution adopted for the present invention to solve the technical problems is: in water heater smoke exhaust pipe upper vertical one gravity sealing device is installed.This device is by sealing gasket, the movable seal in double-deck location, and connection chain, lever, cylindrical shell [comprising lower interface] are formed.The outside is linked to each other with lever by tractive magnet.Water heater power supply and drawing magnetism power supply with being inserted in the supply socket that has a switch.When the needs water heater working, click " opening ", the drawing magnetism adhesive, lever drives gravity seal is opened, and the water heater exhaust blower is opened, and outer smokejack is open-minded.When using up water heater, click " stopping ", drawing magnetism outage, the gravity seal gets into sealing state under the gravity effect, and cool exterior air and water heater completely cut off, and without pressure release, operation such as discharge water, can guarantee that water heater can bursting by freezing.
The invention has the beneficial effects as follows problem that can fundamentally solve the frequent bursting by freezing of north gas heater in winter and the problem that a large amount of electric energy are wasted to have simple in structure, reliable operation, be convenient to install, operate characteristics such as facility.

Claims (3)
- The technical characterictic of gas heater defroster of the present invention is to utilize tractive magnet to move up and down through lever connection drive gravity seal to reach the switching of control water heater smoke exhaust pipe to outdoor exhaust passage, guarantees that water heater is not by simple, the effective scheme of bursting by freezing.The scope of asking for protection is following:1. the version and the profile that constitute by drawing magnetism, connecting rod, gravity seal, sealed base.
- 2. the bilayer of taking in order to guarantee sealing effectiveness is located movable sealed body structure.
- 3. with the control method of combustion gas blower fan synchro switch.
