Electric heater, for many people rush bath with shower, the common electric heater of both the above is full sufficient demand.With life
The raising of level, the problem of much liking the bathing in bathtub leisurely to enjoy life, but run into new is mainly into balneation
Cylinder first puts water well before having a bath, and the bad control of water temperature, temperature is too high then too boiling hot, and people can't stand or hurt sb.'s feelings, and temperature is too low then too cold,
It can not be had a bath for a long time, so existing water heater there is certain defect, thus water heater uses self priming pump cold water
Water inlet pipe access bathtub directly draws water to heat to put again puts back to bathtub by hot water, because self priming pump is having the situation of air（It is i.e. untrue
Empty condition）Under also can normal work, it is possible to solve the above problems, but because self priming pump its shelf-life is shorter, be not suitable for
Work long hours, so cause repair rate very high, to bringing very big inconvenience after sale.
Utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and provides a kind of simple in construction,
The lower electric heater with cold water self-suction function of life-span longer repair rate.
The technical scheme in the invention for solving the above technical problem is：A kind of electric heater, including housing, heater
And self priming pump；The heater and self priming pump are all arranged in housing；The heater is provided with heater water inlet and heater
Delivery port；The self priming pump is provided with self priming pump water inlet pipe and self-priming water pump outlet pipe, and the self-priming water pump outlet pipe is intake with heater
Mouth is connected；It is characterized in that：Circulating pump and tube, heater inlet are had additional in the housing；The circulating pump is provided with circulating pump
Water inlet pipe and circulation water pump outlet pipe；The circulation water pump outlet pipe is connected with self priming pump water inlet pipe；The tube, heater inlet one
End is connected with heater water inlet, and the other end is connected with self priming pump water inlet pipe and circulation water pump outlet pipe respectively；The self-priming
Water pump outlet pipe is connected with tube, heater inlet；Control valve is provided with the tube, heater inlet.The utility model is set certainly
Sucking pump and circulating pump, using that can meet the condition of work of circulating pump by self priming pump self-priming cold water, are then connected by circulating pump
Continuous work, it is sustainable to provide cold water, the cold water flow direction of the setting principal security self priming pump water inlet pipe of control valve for heater, it is ensured that
Cold water flows into the direction of heater, prevents adverse current, so water can be drunk up.
Control valve described in the utility model is check valve or magnetic valve.
The utility model compared with prior art, with advantages below and effect：It is simple in construction, it is reasonable in design, by certainly
The mutual cooperation of sucking pump, circulating pump and each pipeline is set, can play self priming pump have the advantages that air conditionses can also draw and
Its working time and intensity can be reduced, increases service life, maintenance cost is reduced, while also playing circulating pump long-term work
Advantage, is continuously the cold water in heater offer bathtub, makes user's bathtime unrestricted, enjoy life to the full.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and the utility model is described in further detail by embodiment, following examples are pair
It is of the present utility model explanation and the utility model is not limited to following examples.
Reference：Housing 1, heater 2, heater water inlet 21, heater delivery port 22, tube, heater inlet 23,
Check valve 24, self priming pump 3, self priming pump water inlet pipe 31, self-priming water pump outlet pipe 32, circulating pump 4, circulating pump water inlet pipe 41, circulating pump
Outlet pipe 42.
Embodiment：
Referring to Fig. 1, the electric heater of the present embodiment, including heater 2, self priming pump 3, circulating pump 4 in housing 1
With tube, heater inlet 23.Self priming pump 3 is provided with self priming pump water inlet pipe 31 and self-priming water pump outlet pipe 32.Heater 2 is provided with heater
Water inlet 21 and heater delivery port 22.Circulating pump 4 is provided with circulating pump water inlet pipe 41 and circulation water pump outlet pipe 42.
The one end of tube, heater inlet 23 is connected with heater water inlet 21, the other end and self priming pump water inlet pipe 31 and circulation
Water pump outlet pipe 42 is connected.Circulation water pump outlet pipe 42 is also connected with self priming pump water inlet pipe 31.
Self-priming water pump outlet pipe 32 is connected with tube, heater inlet 23, and self-priming water pump outlet pipe 32 passes through tube, heater inlet 23
It is connected with heater water inlet 21.
Check valve 24 is provided with tube, heater inlet 23, can be protected and be flowed to again to greatest extent by cold water using check valve 24
Use cost is saved, while also reducing the maintenance cost of magnetic valve or motor-driven valve.
Operation principle：The circulating pump water inlet pipe 41 of circulating pump 4 is connected to bathtub in electric heater, circulation water pump outlet pipe 42 with
Self priming pump water inlet pipe 31 is connected, during start-up operation, and self priming pump 3 first works, and sucks cold water and enters by circulation water pump outlet pipe 42
Enter heater 2 to be heated, after the inside of circulating pump 4 is full of water, the air discharge in circulating pump 4 and circulating pump water inlet pipe 41,
The condition of work of circulating pump is met in this case, has started circulating pump 4 and be operated, self priming pump 3 is stopped, and cold water passes through
Circulation water pump outlet pipe 42 is connected with self-priming water pump outlet pipe 32 is fed directly to heater 2, from heater water outlet after the heating of heater 2
Mouth 22 is discharged into bathtub, completes working cycles, after continuing or a section works, exists when in circulating pump 4 and circulating pump water inlet pipe 41
Air enters, and circulating pump 4 can be stopped, at this moment, is again started up self priming pump 3, is again started up a cycle period.
The work of circulating pump 4 can be met by the self-priming cold water of self priming pump 3 using self priming pump 3 and being applied in combination for circulating pump 4
Make condition, then continuously worked by circulating pump 4, it is sustainable to provide cold water for heater 2, so it can play self priming pump 3
Have the advantages that air conditionses can also be drawn and its working time and intensity can be reduced, increase service life, reduction repair into
This, while also play the advantage of the long-term work of circulating pump 4, is continuously heater 2 and provides cold water in bathtub, when the user is had a bath
Between it is unrestricted, enjoy life to the full.
It should be noted that：Heater 2, self priming pump 3 and circulating pump 4 are all by electric meter functional module management and control, electric instrument
Table function module includes carrying out detection means with the presence or absence of air in managing in circulating pump water inlet pipe 41, to control the He of self priming pump 3
The start and stop of circulating pump 4, because electric meter functional module is that those skilled in the art need easily to think according to function
The conventional meanses arrived, and be not the emphasis of the application, so being no longer described in detail.
Above content described in this specification is only to the utility model example explanation.The utility model
