Description
Technical field
The present invention relates to a kind of electric heater.
Background technology
Existing electric heater is roughly three classes, one class is that water-storage electric heater, a class are the instant electric water heater, also has a class for being the hybrid battery water heater in advance, take electricity, water storage courage capacity inapplicable long-time heat supply water less than normal when water-storage electric heater length heat time heating time, insulation, and heater easily produces incrustation scale, and service life is short.Though the instant electric water heater is fast heat time heating time, require power big, water temperature rising amplitude is little, and discharge is also less than normal, and when requiring discharge big, power then needs corresponding increase, and general family is difficult to bear.Though be that the hybrid battery water heater can overcome drawbacks more recited above in advance, but require the alternately heating of 2 heaters, the heater that wherein is positioned at the water storage courage is easy to generate incrustation scale reduction of service life equally, and the water temperature in the water storage courage is inhomogeneous, the temperature difference is big, influences result of use.
Summary of the invention
Therefore, the object of the present invention is to provide that heater of a kind of usefulness just can realize that hot water flow is big, firing rate is fast, even water temperature and long-lived electric heater in the use.
The object of the present invention is achieved like this.
A kind of electric heater, comprise the water storage courage, heater, magnetic valve and threeway, water storage courage bottom is provided with water inlet pipe and outlet pipe, it is external that described heater is located at the water storage courage, also be provided with water sucking mouth and water return outlet on the storage water bladder wall, pass through magnetic valve between water sucking mouth and the water return outlet, circularly-supercharged pump, heater and check valve are formed a water stream channel, respectively establish a threeway on described water inlet pipe and the outlet pipe, two threeways all have a port to link to each other with the cold and hot import of mixed water valve, mixing the water valve outlet links to each other with heater, mix between water valve and the heater and be provided with magnetic valve, the delivery port of heater links to each other with the user hot water tap by control valve.
Above-mentioned purpose also can be done further perfect by following technical proposals.
Described heater delivery port place is provided with a threeway, and threeway two ports in addition links to each other with control valve with check valve respectively.
Described control valve is the current inductive switch.
Described water storage courage and heater can be located in the housing jointly, also can divide separately to be opened in the different housings.
Also can establish auxiliary heater in the described water storage courage.
Described mixed water valve is that manual adjustments is mixed water valve or automatic thermostatic water mixing valve.
Structure simplicity of design of the present invention is reasonable, and heater is worked under water is in flow regime, and working environment improves greatly, and increase service life, and even water temperature is used comfortable, greatly energy savings.Shorter, littler than water-storage electric heater preheating time than instant electric water heater power demand, than being that the hybrid battery water heater is simple in structure in advance.
Description of drawings
Accompanying drawing is a structure principle chart of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and occupation mode.
In conjunction with the accompanying drawings, a kind of electric heater, comprise water storage courage 1, heater 2, water storage courage 1 bottom is provided with water inlet pipe 3 and outlet pipe 4, it is external that described heater 2 is located at water storage courage 1, also be provided with water sucking mouth 5 and water return outlet 6 on water storage courage 1 wall, water sucking mouth 5 is located at the below of water storage courage 1, water return outlet 6 is located at the top of water storage courage 1, pass through magnetic valve 7 between water sucking mouth 5 and the water return outlet 6, circularly-supercharged pump 8, heater 2 and check valve 9 are formed a water stream channel, respectively establish a threeway 10 on described water inlet pipe 3 and the outlet pipe 4,11, two threeways 10,11 all have a port to link to each other with mixed water valve 12 cold and hot imports, mix water valve 12 outlets and be provided with magnetic valve 13, magnetic valve 13 links to each other with heater 2, the delivery port place of heater 2 is provided with a threeway 14, and threeway 14 two ports in addition links to each other with current inductive switch 15 with check valve 9 respectively, and current inductive switch 15 links to each other with user hot water tap 16.
If the bathroom installing space is limited, water storage courage 1 can be located at outside the bathroom, and heater 2 control assemblies such as grade can be located in the bathroom.
During preheating, user hot water tap 16 water shutoffs, magnetic valve 13 and current inductive switch 15 disconnect, magnetic valve 7 is opened, circularly-supercharged pump 8 work, and the water in the water storage courage 1 flows out after heater 2 heating from water sucking mouth 5 and flows back to water storage courage 1 from check valve 9, water return outlet 6, when the temperature probe in the water storage courage 1 is visited water temperature to setting value, circularly-supercharged pump 8 quits work, and magnetic valve 7 cuts out, and preheating finishes.The circuit control section is opened magnetic valve 13 automatically, if user hot water tap 16 opens, current inductive switch 15 is closed under flow action, warm water after the preheating and cold water mix enter heater 2 heating after current inductive switch 15 flows out from user hot water tap 16 through mixed water valve 12, magnetic valve 13, for using.
If the water temperature in the water storage courage is not during to setting value, user hot water tap 16 is opened, current inductive switch 15 closures, and magnetic valve 7 cuts out immediately, and magnetic valve 13 is opened, and the warm water of lower temperature and cold water mix directly flow out use through heater 2 instant heatings.
If as long as the water of lower temperature can select to close magnetic valve 13 so, the water in the water storage courage 1 directly flows out from outlet pipe 4,17 after water sucking mouth 5 and water return outlet 6 circulation heating and uses.
Enter the water temperature of water storage courage 1 when higher when summer, do not need preheating this moment, can select the instant heating mode, and magnetic valve 7 cuts out, and circularly-supercharged pump 8 quits work, and water uses for the user through mixing water valve 12, magnetic valve 13, heater 2 and current inductive switch 15.
