Abstract

An electrical water heater capable of storing water by amount comprises a bladder, a heat-preservation layer, a shell and a function displaying window, wherein the external side of the bladder is provided with an installation and maintenance cover plate and a water pump; a gas-guide tube with communicated inside and outside is vertically arranged on the bottom surface of the bladder; an upper port of the gas-guide tube is horizontally higher than a highest floating ball switch Kn, wherein n is more than or equal to 2; a water inlet electromagnetic valve is additionally arranged in front of a water inlet draft tube; a water inlet of a water outlet joint approaches to the bottom surface at the internal side of the bladder; the bladder is internally provided with a temperature measurement probe; and one side surface of the internal side of the bladder is sequentially provided with a water inlet pipe of a water pump, a heating pipe and floating ball switches K1-Kn from bottom to top. The electrical water heater overcomes the defects of electric energy loss as the general storage-type electrical water heater can not deplenish the hot water; the user can select a button by water amount according to personal water using habit for bathing and can select the water inlet amount so as to carry out automatically heating and keep constant temperature; and by adopting a direct drainage mode, all hot water in the bladder can be drained completely, thus eliminating the electric energy loss due to residual hot water.

Description

The component water-storage electric heater

Technical field

The utility model relates to electric heater, particularly a kind of component water-storage electric heater.

Background technology

Existing water-storage electric heater, because its water inlet mozzle directly is communicated with running water pipe, hydraulic pressure is with hydraulic pressure is consistent from the beginning in the inner bag.During shower, need the hot water of capacity high temperature in the water heater, by mixing water valve with high-temperature-hot-water in the water heater and cold water mix from the beginning, regulate to mix when water valve is fit to water temperature and just can use, after so each shower finishes, always have a certain amount of surplus hot water in the water heater, thereby cause waste of electric energy.

The utility model content

Problem at above-mentioned existence, the purpose of this utility model provides a kind of component water-storage electric heater, and it can select different inflows to intake automatically and heat by the custom of taking a shower, and makes water temperature integral body constant, all hot water in the energy emptying inner bag, and can realize the digital demonstration of water level.

The technical solution of the utility model is: the inner bag outside is provided with installation and maintenance cover plate and water pump, the vertical wireway that is interlinked to the outside in of installing in the inner bag baseplane, and wireway upper port level is higher than the highest float switch K _n, wherein n 〉=2 install an entering water electromagnetic valve additional before the water inlet mozzle, and the water inlet of water out adapter is equipped with temperature probe near the inboard baseplane of inner bag in the inner bag, and a side of inner bag inboard is installed pump water inlet, heating tube, float switch K from low to high successively ₁-float switch K _n

Any natural number in the number n of float switch desirable 2～9.

The utility model has the advantages that: the utility model is by the vertical wireway that is interlinked to the outside in of installing in the inner bag baseplane, makes that hydraulic pressure remains under the nature in the inner bag, and draining and water feeding pressure are worked under low state; The water inlet of water out adapter is convenient to hot water all in the emptying inner bag near the inboard baseplane of inner bag; The inner bag outside is equipped with water pump, at heating tube work while pump working, makes the cold water of bottom and the hot water on upper strata mix, and reaches the purpose of whole even water temperature unanimity; Float switch K1-float switch Kn and entering water electromagnetic valve constitute inflow automatic control from low to high, and water level is digital to be shown, can show the water situation in real time.

The user can pass through water yield selector button according to individual's shower water custom, and how much that can select inflow carries out automatic heated constant temperature, adopts direct discharging modes, and all hot water in the energy emptying inner bag reaches and eliminates the energy loss that the surplus hot water causes.

The specific embodiment

Now in conjunction with the accompanying drawings, technology contents of the present utility model is described in detail.

By Fig. 1 and Fig. 2 as can be known, the vertical wireway 2 that is interlinked to the outside in of installing in inner bag 1 baseplane, wireway 2 upper port levels are higher than a highest float switch K _n12.Water inlet mozzle 5 top closure, both sides have delivery port, and water can flow in the inner bag from the both sides level like this.Wherein intake mozzle 5 perpendicular to inner bag 1 baseplane, and the delivery port level of water inlet mozzle 5 is lower than first float switch K ₁11, can reduce the fluctuation of water when intaking like this.Entering water electromagnetic valve 6 is connected the into water inlet place of water mozzle 5.The water inlet of water out adapter 9 is convenient to hot water all in the emptying inner bag near inner bag 1 inboard baseplane.Water pump 13 is installed in inner bag 1 outside as the water admixing device of lower floor's cold water and upper strata hot water, from the cold water of pump water inlet 10 suction, by pumping line 16 be connected flexible pipe 14, evenly mix with the hot water on upper strata.Wherein water pump 13 standard of fuselage are lower than float switch K ₁11 position.In a side of inner bag 1 inboard that water pump 13 is installed, pump water inlet 10 is installed in the below of U type heating tube, and U type heating tube is installed in float switch K ₁11 belows, float switch K ₁11 to K _n12 install from low to high successively, and the temperature probe 17 in the inner bag 1 is installed in same horizontal level with U type heating tube.

Control procedure of the present utility model (control circuit is seen Fig. 3):

In Fig. 3, the plug that plugs in, D1 lights, and start button S2 is pressed in the display power supply indication, and D6 lights, and shows to select first grade of water yield, and charactron DS shows " 0 ", entering water electromagnetic valve D energising begins water inlet.When water rises to float switch K1, make the K1 closure, entering water electromagnetic valve D outage stops into water, and charactron DS shows " 1 ", and while U type heating tube R and water pump MG get electric, heating and pump working, after temperature is heated to setting value, U type heating tube K and MG dead electricity.Press start button S2, again by water yield selector button S3, by the float switch of correspondence, can realize that the multiple water yield controls automatically, charactron DS shows equivalent water level simultaneously.Close water button S5 and can realize manually closing water in the water inlet process, water inlet is selected higher one grade of water yield by water yield selector button S3 after finishing automatically, can realize intaking automatically once more by water inlet button S4 again.Can realize automatic constant-temperature control by mechanical temperature controller or electronic temperature controller, stop button S1 can make complete machine be in little electric current holding state.
