Description

Electricity separation Split type gas hot water spit of fland controller

Technical field

The utility model patent relates to that a kind of Split type gas hot water spit of fland self-con-tained unit, especially controller and gas and hot water spit of fland are installed on respectively that indoor and outdoor and high voltage are all positioned at controller and the self-con-tained unit that separates with body.

Background technology

For current a kind of novel Split type gas hot water spit of fland that is applicable to southern area locellus heating, what now adopt is general temperature controller, in order to control the switch of 220V voltage in hot water spit of fland. Hot water spit of fland is made up of controller, radiator and gas-fired water heater, gas-fired water heater is made up of low-pressure pump, pulse igniter, gas electromagnetic valve, fire grate and heating water tank, gas-fired water heater is placed in outdoor, controller and radiator are placed in indoor, and operator directly realizes the control to equipment by the man-machine interface of controller. This design is through the simulation checking to southern climates heating demand, and equipment is simple, easy for installation, is convenient to maintenance, and comfortableness is good, is very suitable for the locellus heating of southern area.

What the existing controller using on this novel gas hot water spit of fland adopted is the switch control form of 220V circuit, and 220V power supply is placed in off-premises station, and by indoor controller, according to user of service's setting, output signal is controlled cut-offfing of 220V operating voltage. But because equipment is by power supply, combustion gas, water concentrates on a place, and existing leaks makes equipment conduction, the serious potential safety hazards such as combustion gas of igniting of leaking electricity, thus in equipment, need to adopt a lot of safe designs to increase a lot of design costs, and device line complexity.

Summary of the invention

The utility model provides a kind of novel control device that is applicable to Split type gas hot water spit of fland, and this device has overcome the shortcoming of existing gas and hot water controller design, has inherited its design and installation conveniently, is convenient to the feature of maintenance and inspection. The problem solving comprises leaking and causes 220V short circuit, and the conduction 220V voltage that leaks is to casing, the 220V voltage short circuit coal gas that ignites, and touch control process is away from combustion gas forceful electric power.

The utility model solves the technical scheme that its technical problem adopts: control device is placed in together with man-machine interface to controller and is built in indoorly, gas and hot water equipment is placed in outdoor casing, connect between the two by control circuit. Power supply and safeties are arranged on controller, the water pump transformer that gas-fired water heater is required, and pulse igniter transformer, control circuit transformer is set directly in controller. In controller, source current is transported to after three in parallel transformation coils through ballast by safeties, the 3V input voltage of output pulse igniter, and water pump 24V operating voltage, control circuit 5V normal voltage is in control circuit. Indoor temperature transmitter, intake-outlet temperature sensor, directly be connected in the lump on control circuit, controlled according to the setting value of man-machine interface by computing module, control water pump voltage, whether pulse igniter voltage outputs in gas-fired water heater is gone, and with temperature in accurate automatic control room, and by display chip, real-time room temperature and control situation is shown in man-machine interface. Like this, 220V voltage only acts on controller under the effect of safeties, only has the 3V input voltage of pulse igniter in casing gas-fired water heater, and water pump 24V operating voltage all below 36V human electric shock voltage, and is not enough to the combustion gas of igniting. When the utility model just can effectively solve water in conventional tank, high voltage, combustion gas and coexists, leak and cause 220V short circuit, the conduction 220V voltage that leaks causes and gets an electric shock to casing, and 220V voltage circuit damages the coal gas that ignites. The utility model separates high voltage completely with water and combustion gas, controller is separated to the security that has greatly improved Split type gas hot water spit of fland with gas-fired water heater, reliability, has reduced original controller secure design cost, and is only connected and installed easy to use by control circuit.

The beneficial effects of the utility model are: electricity separation, and safe and efficient, comfort and convenient, cost is low, economic and practical.
