Abstract
The utility model relates to a gas water heater. The purpose of the utility model is to provided a forced gas-supply-exhausting type dual-purpose gas water heater for heating and bathing which can ensure that a combustion chamber generates negative pressure before a burner working normally, and a double-flue full-sealed structure is used for improving the security of the burner. Thus, a smoke exhaust fan is arranged on the upper end of the burner in the utility model; a sealed smoke exhaust chamber is arranged on the upper end of a heat exchanger, and the sealed smoke exhaust chamber is communicated with an exhaust flue of a double-way chimney; a micro-pressure relay is arranged at the extremity of a gas inlet flue mouth of the double-way chimney, and the micro-pressure relay is used for opening a control program controller, thereby, improving the safety and the reliability of the burner, and the utility model is an ideal gas water heater.
Description
The utility model belongs to gas heater.
Traditional gas heater, the upper end of main ignition combustor is provided with heat exchanger, cooling water inlet is communicated with heat exchanger one end by water inlet pipe with cold water, and the cold water that enters from cooling water inlet heats the hot-water supply use after the outlet pipe of its opposite side communicates with shower nozzle in heat exchanger.The waste gas of combustion chamber is derived outdoor along the outlet flue of casing upper end by chimney, duty with controller control burner, and the power switch on the controller is realized by hydromagnetic float triggering reed switch relay in the water inlet water film valve, discharge to one in water inlet pipe regularly, hydromagnetic lifts the tongue tube adhesive with power connection, the hydromagnetic float sinks when closing into water, and reed switch relay disconnects, and power supply is cut off.Controller is by timer, the firepower control circuit, and sound light alarming circuit, the high-voltage pulse firing circuit, institutes such as temperature sensing circuit form the igniting that is used to control burner, functions such as automatic safe cutoff.
But this traditional water heater is when igniting, because cold air of saving in the chimney and burner are by the natural wind circulation, smoke evacuation indoor hot-air in igniting back can not be extruded cold air in the chimney, fresh air just can not enter the combustion chamber, cause burning not smooth, the combustion chamber is oozed out in combustion gas, and security is relatively poor.Therefore guarantee to produce certain negative pressure in the combustion chamber, the waste gas discharge and the entering of fresh air that are beneficial to the combustion chamber are the urgent problems that solves of current combustion device.
The purpose of this utility model provides the dual-purpose gas heater of a kind of pressure supply and exhaust formula heating and bathing, guaranteeing before the burner operate as normal, to make the combustion chamber produce negative pressure, and adopts the twin flue all-sealed structure, to improve the security of burner.
The utility model is by heat exchanger, main ignition combustor and cyclelog etc. are formed, be provided with the smoke exhaust fan device in the heat exchanger upper end, the heat exchanger upper end connects sealing and is provided with the smoke evacuation chamber, the smoke evacuation chamber communicates with smokejack, air inlet end at the air inlet flue is provided with the minute-pressure relay, and the minute-pressure relay is serially connected on the circuit of opening program controller, and smokejack and air inlet flue are the two pass chimney that is positioned at one.The said structure design has realized the purpose of this utility model.
The utility model has the advantages that: guarantee safety, the security performance height, adopt the guide of minute-pressure relay as cyclelog, produce about 35-48pa negative pressure rear connection cyclelog in the combustion chamber and carry out operate as normal to guarantee that air exhauster turns round to make after about 6 seconds, thereby guaranteed the combustion chamber normal combustion, improved security.Adopt the two pass chimney simultaneously, an available two pass chimney is finished discharging waste gas and inspiration outdoor fresh air, and is easy to install.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model schematic diagram
Fig. 2 is the utility model two pass chimney user mode schematic diagram
The utility model is by heat exchanger 14, main burner 13, water film valve 12, and water temperature regulating handle 11, cooling water inlet 10, triple valve 9, fuel gas inlet 8, gas valve 7, plug 6, cyclelog 5, shower nozzle 4 and overheat protector 3 are formed.Be provided with smoke exhaust fan 16 in the heat exchanger upper end.The heat exchanger upper end connects sealing and is provided with smoke evacuation chamber 15, the smoke evacuation chamber communicates with smokejack 17, be provided with blower fan between smokejack and the smoke evacuation chamber, the smokejack outer end is an air inlet flue 1, air inlet end at the air inlet flue is provided with minute-pressure relay 2, the minute-pressure relay is serially connected on the circuit of opening program control, and smokejack and air inlet flue are the two pass chimney that is positioned at one.The minute-pressure relay can be blast switch, and its operating pressure is 35-36pa.The operating pressure 35-48pa of minute-pressure relay.The minute-pressure relay can be serially connected in the circuit between water film valve reed switch relay and the cyclelog.
The utility model is a kind of improvement structure; heat exchanger, main burner, water film valve, water temperature regulating handle, cooling water inlet; triple valve, fuel gas inlet, gas valve, plug, cyclelog, shower nozzle and overheat protector are the traditional structure position; the conversion of heating and bathing is a traditional structure also, so be not repeated.
In the smoke evacuation chamber 15 that the upper end, combustion chamber is tightly connected airtight, upper end, smoke evacuation chamber sets out mouth, directly communicates with the exhaust uptake 17 of two pass chimney.The two pass chimney is big young waiter in a wineshop or an inn's chimney of the different-diameter that connects together, and the inner width between two chimneys has support, and the gap constitutes the air inlet flue.The seal casinghousing of main burner upper end because the housings close of main burner upper end, air inlet flue then communicate.The air inlet flue that formation enters fresh air communicates with the main burner lower end, and exhaust uptake communicates with the smoke evacuation chamber, forms good recycle seal system.The air-breathing mouth of pipe of minute-pressure relay 2 or negtive micropressure switch is at the air inlet end of air inlet flue, and their pilot is serially connected on the circuit of opening program controller.Also can be serially connected in the circuit between water film valve reed switch relay and the cyclelog.Blower fan 16 is positioned on the interface of the exhaust uptake on the smoke evacuation chamber.Blower fan directly communicates with power switch.
During use, connect power supply, open 16 runnings of Cold water tap smoke exhaust fan, the room air of will discharging fume is discharged outdoor, makes combustion chamber to can form a 35-48pa negative pressure, so fresh air is by in the air inlet flue 1 inspiration water heater.This intake process is connected minute-pressure relay or blast switch, thereby connects the cyclelog circuit, opens just combustion gas of hot-water valve this moment.Flow out hot water, if flue partly stops up or formula water heater burning die cavity is poorly sealed, when negative pressure is lower than 35pa in the combustion chamber, just interrupt routine controller circuitry of minute-pressure relay then, the gas valve valve cuts out automatically, and water heater can't use, to guarantee safety.
In a word, the utility model security performance is good, and combustion efficiency is good, can save combustion gas, and being convenient to install is a kind of desirable gas apparatus water heater.
