Description

Separated electric film fast water heater
The utility model relates to the water heater that is used for bathing.
Have two kinds with electric energy as the water heater of thermal source, a kind of is fast water heater, and a kind of is storage water heater.Fast water heater is in the coating of glass water container coated outside ceramic membrane, and when ceramic membrane was switched on, the water of ceramic membrane heating and heating glass water container inside directly supplied bath water.Though fast water heater has the advantage of Fast Heating, its weak point is that power is big, and water yield is little, just can't use in the winter of cold.Storage water heater is to heat by the electrothermal tube that is installed in the water tank, plays bath when making water temperature in the water tank reach the requirement temperature again.Its weak point is that electrothermal tube does not separate with water, and is dangerous; Preheating time is long; In case hot water uses up in the water storage tube, wait next time in the water storage tube and could use after the water heating, can not continuous water supply, so the storage water heater volume that has is done very greatly; The water temperature delamination difference causes the leaving water temperature instability, regulate trouble of water temperature during bathing, and the thermal efficiency is low.
The purpose of this utility model is to overcome above-mentioned weak point and a kind of separated electric film fast water heater is provided, under the situation of not very big power (the average family energy meter can bear), even also can well-off quickly hot water during the winter bathing; Electricity separation, safety; Thermal efficiency height; Energy hot water without interruption, volume is also little; Leaving water temperature is stable.
Description of the present utility model is as follows: separated electric film fast water heater is made up of the compound coating of glass water container, ceramic membrane and PTC, water storage tank, mixed water jet valve, unidirectional electrical magnet valve, level sensor control circuit, temperature control circuit.Running water is entered by the cold water end that mixes the water jet valve.Between mixed water jet valve and glass water container, connect a unidirectional electrical magnet valve.The glass water container is a container, and an end is connected by pipeline and unidirectional electrical magnet valve, and the other end is connected by pipeline and water storage tank.In glass water container coated outside ceramic membrane and the compound coating of PTC, the compound coating of ceramic membrane and PTC is a heater, and heating and heat passed to the water of water container inside during energising makes the water heating.In glass water container outside PTC themistor is housed, thermal resistor is connected with temperature relay, unidirectional electrical magnet valve again.Prescribe a time limit when water temperature in the water container reaches on the design temperature, PTC themistor impels temperature relay to open the unidirectional electrical magnet valve, and under tap water pressure, hot water is pressed by pipeline from water container and is passed to water storage tank.Because entering of cold water, water temperature descends in the water container, prescribe a time limit when dropping under the design temperature, PTC themistor impels temperature relay to close the unidirectional electrical magnet valve, cut off entering of running water, the water of water container inside is under the effect of ceramic membrane and the compound coating heater of PTC, again heat up, when temperature is raised to going up in limited time of design temperature, PTC themistor opens the unidirectional electrical magnet valve by temperature relay once more, by tap water pressure hot water in the water container is pressed once more and be passed to water storage tank, unidirectional electrical magnet valve discontinuous operation like this is again and again to the hot water of water storage tank supply uniform temperature.Water storage tank top has the hole, does not have confining pressure.There is the hot water end of joint and mixed water jet valve to be connected at water tank bottom, is connected to the pouring shower nozzle by pipeline again, for beating water for shower.
Separated electric film fast water heater is provided with power selector switch, can select watt level according to the temperature difference.The solenoid control switch also is housed on water heater of the present utility model, in weather hot season, disconnect the solenoid control switch, the PTC thermistor is not worked, temperature relay impels the unidirectional electrical magnet valve to open normal open, and running water continuously flows to the glass water container.The water of water container inside presses to be passed in the water storage tank after ceramic membrane and the compound coating heater heating of PTC continuously.Be provided with water level controller in the water storage tank, two probes are arranged on water level controller, be contained in respectively on high-water line and the low water line.High water level probe normally closed relay in parallel, low water level probe normally opened relay in parallel.Two electrodes of probe are a segment distance separately, when the high water level probe touches liquid level, forms electrical conduction current, impels normally closed relay to cut off circuit water heater is quit work; If water level is reduced to below the low water level, the low water level probe cuts off electric current, impels normally opened relay to be in the connection circuit state, makes heater work.The utility model water heater also is provided with the heater of PTC heating sheet and fan composition, in order to improve environment temperature, dries up hair.
