Description
Technical field
The present invention relates to the boiler field, specifically relate to a kind of electric water boiler.
Background technology
Existing electric water boiler all is to adopt the single contact float switch to control water intake valve, and namely water intaking valve just can be opened water inlet when water level is discontented.Adopt this mode can realize the automatic water inlet of electric water boiler, guarantee that the water in the electric water boiler water tank is in the full state that carries all the time.But unboiled water entered among the boiling water when this mode can exist in relieving water, thereby people's health is drunk in influence.
In order to address this problem, this class electric water boiler can arrange the time that time-delay relay postpones water intake valve.Though the existence of time-delay relay can make entering after having put water of unboiled water, as long as the temperature of water is on the setting of temperature inductor after mixing, heating tube is not worked so, and unboiled water will exist in boiling water.And if we the critical value of temperature inductor transfer too high, then can cause the work of heating tube repeated multiple times, waste energy, reduce the service life of electric water boiler.
Summary of the invention

Further, described electric water boiler also comprises tap, and the delivery port place of described tap is provided with water outlet and chews.
(3) beneficial effect
Electric water boiler of the present invention simple in structure easily manufactured, can prevent boiling water and unboiled water mix the back directly used, energy-conservation.
Description of drawings
Fig. 1 is the structural representation of electric water boiler of the present invention;
Fig. 2 is the structural representation of electric water boiler circuit part of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
The structure of a kind of electric water boiler of the present invention as shown in Figure 1, the structure of electric water boiler circuit part of the present invention is as shown in Figure 2; Comprise floating-ball level switch, water intaking valve, relay M and water tank 1; Described floating-ball level switch comprises inductive switch 21, following inductive switch 23, ball float 22 and guide post 24; Described upward inductive switch 21 places the upper end of described water tank 1, and described inductive switch 23 down places the lower end of described water tank 1, and described upward inductive switch 21 and described inductive switch 23 down place the two ends of described guide post 24 respectively; Described ball float 22 passes described guide post 24, floats with liquid level height in the water tank 1, and described ball float 22 is used for touching described inductive switch 21 and the following inductive switch 23 gone up.
The structure of electric water boiler circuit part of the present invention as shown in Figure 2, described down inductive switch 23 be normally opened contact, described on inductive switch 21 be normally-closed contact, the contact M1 of described relay M is normally opened contact; Described upward inductive switch 21 and described inductive switch down 23 are connected, and form self-hold circuit with described relay M; Described inductive switch down 23 is connected, and described self-hold circuit is connected and kept; The described inductive switch 21 of going up disconnects, and described self-hold circuit disconnects; When described self-hold circuit is connected, described water intake valve, when described self-hold circuit disconnected, described water intaking valve was cut off the water supply.Y represents the output of water intaking valve in circuit diagram.
After boiling water bled off, water intaking valve feed-tank 1 at once discharged water like this, but after needing water tank 1 central water to be reduced to a certain degree, namely played inductive switch 23 places.Ball float 22 shake-up this moment are inductive switch 23 down, thereby self-hold circuit is connected water intaking valve is discharged water.Rise at water level, ball float 22 leaves down inductive switch 23, but because the self-sustaining effect of self-hold circuit makes circuit be in on-state all the time.When water level rises to inductive switch 21 places, inductive switch 21 touches on this moment, and originally normally-closed contact is converted to disconnection, self-hold circuit disconnection this moment, and water intaking valve stops to discharge water.So circulation.
When water level dropped to inductive switch 23 places, this moment, the prompting user did not use because water tank 1 interior water seldom, enters a spot of water its water temperature is reduced under the temperature control influence value, thereby show heated condition.Directly released use by the user after so just can avoiding unboiled water and boiling water mixes, also avoided because the continuous adding of unboiled water causes electric water boiler to heat continuously, thus energy savings.
Wherein, described upward inductive switch 21 and described inductive switch 23 down are tongue tube, are provided with magnetosphere in the described ball float 22.
Wherein, described electric water boiler also is provided with anti-dry ball float 5.When short water, described putting dryouied ball float 5 and can be cut off the electricity supply, and prevents the electric water boiler dry combustion method.
Wherein, the tank wall of described water tank 1 is divided into internal box wall, external box wall and foaming layer, and described foaming layer places between described internal box wall and the external box wall.This structure can effectively be incubated, energy savings.
Wherein, described electric water boiler also comprises tap 4, and the delivery port place of described tap 4 is provided with water outlet and chews.This structure can be adjusted the current of water outlet, prevents that tap 4 from spraying the scald human body.
Beneficial effect of the present invention: simple in structure easily manufactured, can prevent boiling water and unboiled water mix the back directly used, energy-conservation.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
