Abstract
A gas-combustion water heater control device for stopping water and controlling temperature comprises a heat exchanger, a hot water outlet pipe, a cold water inlet pipe which is provided with a current sensor. The main technical characteristics are that the utility model also comprises a control device which employs a current sensor which as an input element and an on-off valve which is controlled by the control device and which is arranged beside a cold water by-pass pipe. The inlet port of the cold water by-pass pipe is communicated with the cold water inlet pipe, and the output port of the cold water by-pass pipe is communicated with the hot water output pipe. The utility model can lower the water temperature, stabilize the water-yielding temperature, and effectively avoid the scald or discomfort.
Description
Technical field: the utility model relates to a kind of gas heater temperature rising control device of cutting off the water.
Background technology: existing gas heater is cutting out water intaking valve to the blink of cutting off source of the gas, stationary water in the heat exchanger can be heated above the leaving water temperature of setting, the temperature rise phenomenon appears cutting off the water, when opening again in the blink after closing water intaking valve, the initial hot water that flows out may cause the bather to be scalded or discomfort in the hot-water line.For overcoming these defectives, the gas heater temperature rising control device of cutting off the water is developed.
Summary of the invention: technical problem to be solved in the utility model provides a kind of gas heater temperature rising control device of cutting off the water, and it can reduce the temperature rise of cutting off the water effectively, makes leaving water temperature comparatively stable, avoids effectively scalding or uncomfortable.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises heat exchanger, hot water outlet pipe and the cold water inlet that is equipped with water flow sensing unit, be provided with the controller of water flow sensing unit as input block, be controlled by the on-off valve on the cold water bypass pipe of being installed on of controller, the water inlet of cold water bypass pipe is connected with cold water inlet, delivery port is connected with the hot water outlet pipe.
Described on-off valve is a magnetic valve.
Described on-off valve is the spool of stepper motor, and the spool that stepper motor drives its rotation carries out break-make.
The utility model is compared the beneficial effect that is produced with prior art:
1, owing to having adopted, the utility model is provided with the controller of water flow sensing unit as input block, the on-off valve on the cold water bypass pipe of being installed on that is controlled by controller, the cold water bypass pipe structure that communicates with cold water inlet and hot water outlet pipe, so it can reduce the temperature rise of cutting off the water effectively, make leaving water temperature comparatively stable, avoid effectively scalding or discomfort.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
The specific embodiment: referring to accompanying drawing 1, it comprises heat exchanger 6, hot water outlet pipe 7 and be equipped with the cold water inlet 1 of water flow sensing unit 2 is provided with and adopts the controller 3 of water flow sensing unit 2 as input block, is controlled by the on-off valve 4 on the cold water bypass pipe 5 of being installed on of controller 3.
When the gas heater operate as normal, controlled on-off valve 4 is in closed condition, and all cold water enters heat exchanger 6 heating through cold water inlet 1, water flow sensing unit 2, and hot water flows out through hot water outlet pipe 7 afterwards.
After gas heater operate as normal a period of time, close when again it being opened in the blink behind the cold water inlet 1, water flow sensing unit 2 sends control signal makes controller 3 open Bypass hose 5 by on-off valve, the part of external cold water enters heat exchanger 6 through water inlet pipe 1, flows out through hot water outlet pipe 7 again; Another part cold water enters hot water outlet pipe 7 again and mixes the back outflow with high-temperature-hot-water through bypass pipe 5, has effectively reduced the temperature rise phenomenon of cutting off the water of gas heater.Water flow sensing unit 2 size of discharge is after testing determined the time that on-off valve 4 is opened, it is controlled recovery closed condition that time one crosses on-off valve 4, cold water enters heat exchanger 6 by cold water inlet 1 entirely, is flowed out by hot water outlet pipe 7 again, and gas heater changes normal operating conditions over to.
