Description
Technical field: the present invention relates to a kind of gas heater with defroster.
Background technology: existing gas heater, the water pipe in the heat exchanger is because of the water freezing spalling in managing in the gas heater when preventing that environment temperature is low, and existing technical scheme adopts following three kinds of antifreeze modes usually: electrical heating antifreezing, combustion gas heating and anti-freezing, the draining of manual drainage valve; Preceding two kinds of antifreeze modes must civil power could operate as normal; Need heating constantly simultaneously, and consume a large amount of energy, electrical heating antifreezing and combustion gas heating and anti-freezing all can't be worked under situation about having a power failure; The draining of manual drainage valve needs user's manual operations draining valve to discharge water; The user usually can forget and discharges water in actual the use, and causes the gas heater inner water tube by bursting by freezing, causes to exist defroster to waste energy; Can't be normally antifreeze under the power failure situation, defective such as automaticity is low.For overcoming these defectives, the gas heater of band defroster is developed.
Summary of the invention: technical problem to be solved by this invention is that a kind of gas heater with defroster will be provided, and it does not need consumes energy, can be antifreeze effectively under the power failure situation, and automaticity is high.
The technical scheme that the present invention solves its technical problem employing is: it comprises water pipe, magnetic valve, controller, heat exchanger, smoke pipe; Controller and magnetic valve electrically connect, and it also comprises antifreeze unit, and described antifreeze unit comprises antifreeze relief tube, piston, spring, seal cover; Piston be installed in the inboard of antifreeze relief tube front end water inlet and with antifreeze relief tube movable sealing; Seal cover is provided with the hole, and seal cover is connected in the end of antifreeze relief tube, and spring is installed in the antifreeze relief tube; Both ends of the spring respectively with the interior side contacts of piston and seal cover, antifreeze unit is communicated with water pipe through the water inlet of antifreeze relief tube.
It also comprises sealing ring, and described sealing ring is enclosed within on the piston.
Heat exchanging water pipe's union elbow place is equipped with antifreeze unit in the described water pipe.
Antifreeze unit is installed on the water inlet pipe in the described water pipe.
Antifreeze unit is installed on the outlet pipe in the described water pipe.
The sectional area of described antifreeze relief tube is more than or equal to the sectional area of water pipe.
Be with more than one sealing ring on the described piston.
The present invention compares the beneficial effect that is produced with background technology:
1, because the present invention adopts antifreeze unit, and antifreeze unit comprises antifreeze relief tube, piston, spring, seal cover, piston be installed in the inboard of antifreeze relief tube front end water inlet and with antifreeze relief tube movable sealing; Seal cover is provided with the hole; Seal cover is connected in the end of antifreeze relief tube, and spring is installed in the antifreeze relief tube, both ends of the spring respectively with the interior side contacts of piston and seal cover; The structure that the water inlet of antifreeze unit through antifreeze relief tube is communicated with water pipe; So it does not need consumes energy, can be antifreeze effectively under the power failure situation, automaticity is high.
Description of drawings: Fig. 1 is a structural representation of the present invention.
Fig. 2 is the annexation enlarged diagram of antifreeze unit 2 and water pipe 1 among Fig. 1.
The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, present embodiment comprises water pipe 1, antifreeze unit 2, and antifreeze unit 2 comprises antifreeze relief tube 4, piston 7, spring 8, sealing ring 9, seal cover 10, magnetic valve 13, controller 14, heat exchanger 15, smoke pipe 16; Controller 14 electrically connects with magnetic valve 13; Piston 7 is installed in the inboard of antifreeze relief tube 4 front end water inlets 3, and with antifreeze relief tube movable sealing, seal cover 10 is provided with hole 12; Hole 12 can be hole, groove etc.; Sealing ring 9 is enclosed within on the piston 7, and the quantity of sealing ring 9 can be more than one, as 1,2,3,4 etc.; Seal cover 10 is connected in the end of antifreeze relief tube 4; Spring 8 is installed in the antifreeze relief tube 4, spring 8 two ends respectively with the interior side contacts of piston 7 and seal cover 10, antifreeze unit 2 is communicated with water pipe 1 through the water inlet 3 of antifreeze relief tube 4.Antifreeze unit 2 can be installed in heat exchanging water pipe's 11 in the water pipe 1 union elbow place, also can be installed in the water pipe 1 on water inlet pipe 5 or the outlet pipe 6.Antifreeze unit 2 is installed in antifreezing effect on the heat exchanging water pipe 11 and is superior to antifreeze relief tube 4 and is installed on water inlet pipe 5 or the outlet pipe 6, and a plurality of antifreeze unit 2 are installed in antifreezing effect on the heat exchanging water pipe 11 and are superior to single antifreeze unit 2 and are installed on the heat exchanging water pipe 11.Antifreeze relief tube 4 can be respectively and heat exchanging water pipe 11, water inlet pipe 5, outlet pipe 6 global formations, and 2～12 antifreeze unit 2 can be installed on the water pipe 1.In the present embodiment, 5 antifreeze unit 2 are installed in respectively on heat exchanging water pipe 11 union elbow, water inlet pipe 5 and the outlet pipe 6, are with a sealing ring on the piston 7.
Water heater is when normal the use; The pressure of running water acts on the end face of piston 7 in the antifreeze unit 2; The piston 7 that promotes in the antifreeze unit 2 moves to seal cover 10 directions; Compression spring 8 reaches the dynamic balance on piston 7 both sides, and at this moment antifreeze unit 2 is in poised state, in the antifreeze relief tube 4 at piston 7 and the space that also has enough pistons 7 to move between near seal cover 10.
When environment temperature is low; Water freezing in heat exchanging water pipe 11 in the water pipe 1, water inlet pipe 5, the outlet pipe 6 solidifies; Volume becomes big behind the water freezing, promotes piston 7 extrusion springs 8, and moves to the direction of seal cover 10; Discharge in the hole 12 of air in the antifreeze relief tube 4 from seal cover 10; The part ice cube gets in the antifreeze relief tube 4, has reduced after the water freezing volumetric expansion ice cube greatly to the pressure of water pipe in the water pipe 1, when avoiding environment temperature low in the gas heater water pipe in the heat exchanger because of the water freezing spalling in managing.Antifreeze unit 2 does not need civil power, does not need user's manual operations draining valve to discharge water yet, so it does not need consumes energy, can be antifreeze effectively under the power failure situation, and automaticity is high.Can be applicable to gas heaters such as chimney flue type gas heater, balanced type gas heater, forced exhaust formula gas heater, pressure supply and exhaust formula gas heater.
