Description

Full-automatic gas water heater

The utility model relates to a kind of water heater, particularly a kind of full-automatic gas-fired water heater.

Existing water heater exists a fatal defective, must be safely in the bathroom when promptly having a bath, and the bathroom space of general family is narrow and small, and improper ventilation, in the bathroom, use the water heater time long slightly, accident such as promptly fall in a swoon easily, imperfect combustion produces anthracemia just in case water heater gas leakage also can produce the combustion gas poisoning, uses this water heater to cause personnel death's accident that generation is arranged.In order to stop the generation of this accident, one of way of solution is that water heater is installed in outside the bathroom, and the user only needs control cold water switch and remote control knob in the bathroom, can obtain required hot water.A kind of remote-control water heater is disclosed in the Chinese patent (patent No. 922290881).It can realize above-mentioned distant control function.But its complex structure, cost are very high, operate complicatedly, and it is convenient inadequately to use.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of simple and reasonable, and cost is lower, convenient and practical full-automatic gas-fired water heater.

The purpose of this utility model can reach by following measure: a kind of full-automatic gas-fired water heater, comprise burner, heat exchanger, water regulating valve, the gas control valve, hot water outlet, fuel gas inlet, cooling water inlet, controller, battery case, the igniting pin, flame detects pin, ignition switch, motor, housing, it is characterized in that: also have reducing gear, transmission mechanism, the motor rotation control circuit, limit switch XK1, XK2, reducing gear respectively with water regulating valve, the gas control valve fuses, motor is connected with reducing gear by transmission mechanism and by the limit switch AXK1 that is loaded in the water heater, XK2 is spacing, the contact K of the contact b of duplex press button AN1 and duplex press button AN2 joins, the contact c of AN1 and the contact j of AN2 join, the contact e of AN1 joins by the contact h of limit switch XK2 and AN2, the f contact of AN1 joins by the l contact of limit switch XK1 and AN2, the a of AN1, d contact and battery join, the g of AN2, j contact and motor join.

The purpose of this utility model is also to reach by following measure: transmission mechanism adopts connecting rod or gear mechanism.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the electrical schematic diagram of the utility model motor rotation control circuit.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, the utility model is made of burner 1, heat exchanger 2, water regulating valve 3, gas control valve 4, hot water outlet 5, fuel gas inlet 6, cooling water inlet 7, controller 8, battery case 9, igniting pin 10, flame detection pin 11, ignition switch 12, motor 13, slowing-down structure 14, transmission mechanism 15, housing 16, limit switch XK1, XK2, control button AN1, AN2 etc., reducing gear fuses with water regulating valve 3, gas control valve 4 respectively, and motor 13 is connected with reducing gear 14 by transmission mechanism 15.And limit switch XK1, XK2 are loaded on suitable position in the water heater, are used to limit the movement travel of transmission mechanism 15.Reducing gear 14 can adopt reducing gears commonly used such as gear, worm gear; Transmission mechanism 15 can adopt connecting rod or gear etc.

Controlling organizations such as the auto lighting switch of the existing full-automatic water heater of the utility model reservation, igniter, flame-out protection device have been cancelled the water on the water heater, controlled atmosphere joint knob, increase by a cover motor, reducing gear, and drive water valve and air valve rotate.Just commentaries on classics, counter-rotating and the extreme position of controlling motor with the motor rotation control circuit are spacing.The user presses button AN1, AN2, can realize the water yield to water heater, the adjusting control of tolerance.The control button wiring is drawn outside the water heater, can realize remote control water heater.

The water heater working process is as follows: open cold water switch, cold water enters water heater from cooling water inlet 7, and ignition switch 12 detects water-flow signal simultaneously, 10 sparkings of controller 8 control igniting pins, and water heater fire burns, and hot water flows out from hot water outlet 5.When needs are regulated water temperature, press button AN1(or AN2) give motor 13 to rotate electric current, motor 13 drives water regulating valve 3 gentle control valves 4 simultaneously by reducing gear 14, transmission mechanism 15 to be changeed, wherein on the direction that heats up, the action of water regulating valve 3 is that the water yield is reduced, the action of gas control valve 4 is that gas quantity is strengthened, and so just can obtain the higher water of temperature; Otherwise on the direction of cooling, water regulating valve 3 strengthens the water yield, and gas control valve 4 reduces gas quantity, so just can obtain the lower hot water of temperature.When pressing the control button (AN1, AN2) that heats up or lower the temperature respectively, motor is the difference forward or reverse just, the corresponding hot water that just can obtain different temperatures.

Control button AN1, AN2 can be installed on the water heater, also can add long lead, and button is drawn the water heater main body as RCU.The effect of limit switch XK1, XK2 is that the restriction motor can not rotate to limit direction again when water regulating valve or gas control valve turn to extreme position, and protection motor, reducing gear, transmission mechanism etc. are not damaged.

With reference to Fig. 2, button AN1, AN2 are the duplex button, and travel switch XK1 is the limit switch of AN1 when pressing, and are installed in the extreme position of positive veer; Travel switch XK2 is the limit switch of AN2 when pressing, and is installed in the extreme position of reverse directions.AN1, AN2 are chain mutually again, connect with another button by normally-closed contact separately, and user's misoperation like this, when the forward and backward button was pressed simultaneously, power supply can not damage in short circuit.When pressing when just changeing button AN1, motor obtains forward current and turns round and drive transmission mechanism to positive movement, and when transmission mechanism went to direct limit, the normally-closed contact of limit switch XK1 disconnected, and the forward current loop is cut off, and motor no longer rotates.In like manner, provide reverse current to motor when button AN2 presses, make the motor counter-rotating, XK2 can limit the limit of reverse directions.

The utility model has following advantage compared to existing technology: rational in infrastructure, circuit is simple, and is with low cost, easy to use, practical reliable, and processing ease is safe, can be fit to vast family and use.
