Fig. 3 is a circuit diagram of the present utility model.

Among the figure, (1) electrothermal tube, (2) water boiling pot, (3) magnetic force float, (4) float guide rod, (5) tongue tube, (6) let out the vapour storm valve, (6a) valve body, (6b) valve ball, (6c) wire netting, (6d) net hold-down nut, (6e) nut, (6f) seal washer, (7) water inlet pipe, (8) entering water electromagnetic valve, (9) water pressure safety switch, (10) bailing pipe, (11) insulation boiled water tank, (12) magnetic force float, (13) float guide rod, (14) dried spring chamber, (15) breather pipe, (16) PTC heater element, (17) foam insulation, (18) pipe, (19) cold water jar, (20) tap, (21) tap.

Among Fig. 3, K-water pressure safety switch (9), K1-tongue tube (14), K2-tongue tube (5), D1-lack of water indicator lamp, D2-burner on light, the D3-indicator lamp of intaking, D4-drinks indicator lamp fully, R-electrothermal tube (1), R '-PTC heater element (16), F-entering water electromagnetic valve (8), R1, R2, R3, R4, R5-resistance, C1, C2, C3-electric capacity, J1, J2, J3-relay, J1-1, J2-1, J3-1-relay normally open contact, J1-2, J2-2-relay normally-closed contact, BG1, BG2, BG3, BG4-triode, B1-high-power silicon controlled rectifier.

Electrothermal tube (1) is equipped with in the interior bottom of water boiling pot (2), settles the float guide rod (4) of wearing magnetic force float (3) on jar madial wall, and the tank top is equipped with and is let out vapour storm valve (6), is adorning tongue tube (5) on jar lateral wall; Water boiling pot (2) bottom connects water inlet pipe (7), and water inlet pipe (7) is gone up a series connection entering water electromagnetic valve (8), and water pressure safety switch (9) is housed; The water inlet of bailing pipe (10) is positioned at water boiling pot (2) bottom, and the other end is connected with the top of insulation boiled water tank (11).

Settle the float guide rod (13) of wearing magnetic force float (12) on insulation boiled water tank (11) madial wall, the tank top is connected to breather pipe (15), and a jar lateral wall is provided with tongue tube (14), and a jar outer bottom is provided with PTC heater element (16); The jar bottom has pipe (18) to be connected with cold water jar (19) top; Insulation boiled water tank (11) outside is coated with foam insulation (17); Insulation boiled water tank (11) and cold water jar (19) are respectively equipped with tap (20), (21).The shell body (22) of boiling water machine is represented in double dot dash line among Fig. 1.

The vapour storm valve (6) of letting out of water boiling pot (2) is made up of valve body (6a), valve ball (6b), wire netting (6c), net hold-down nut (6d), and the valve body steam passage is opened at top, valve ball chamber, wire netting (6c) valve ball (6b) be blocked in valve ball indoor in case its deviate from; Valve body (6a) is fixed on the water boiling pot top wall with nut (6e), and seals with seal washer (6f).

Connect with the mains during work, water inlet pipe (7) is connected in entering water electromagnetic valve (8) action, and running water enters water boiling pot (2).Magnetic force float (3) improves along with water level and rises, and when rising to desired location, tongue tube (5) is acted on and the adhesive conducting by magnetic force float (3), and entering water electromagnetic valve (8) is closed and electrothermal tube (1) heating power.Continuous rising along with water temperature, the interior quantity of steam of water boiling pot (2) increases, and air pressure increases thereupon, but the air pressure of this moment is not enough to the valve ball (6b) in the top stopping leak vapour storm valve (6), steam is overflowed from the valve body steam passage, avoids going into to be incubated boiled water tank (11) without the hydraulic pressure of boiling sterilization fully.When water temperature reached boiling temperature, the air pressure that fierce boiling generation is enough ended valve ball (6b) top on the steam passage opening of letting out vapour storm valve (6) and blocks steam passage opening, and the space on the water surface promptly becomes a sealing steam chest at this moment.To seethe with excitement the fully boiling water of sterilization of air pressure presses to insulation boiled water tank (11) through bailing pipe (10), and the water of insulation boiled water tank (11) flows into cold water jar (19) by water pipe (18) again.When water level is reduced to the water inlet that is lower than bailing pipe (10) in the water boiling pot (2), the sealing steam chest communicates with atmosphere by bailing pipe (10), insulation boiled water tank (11) internal upper part space, breather pipe (15), steam chest becomes open steam chest, steam is discharged rapidly, and the valve ball of letting out in the vapour storm valve (6) (6b) falls because of deadweight.When boiling water extrudes, reducing the magnetic force float (3) that descends with liquid level causes tongue tube (5) to disconnect, electrothermal tube (1) disconnects and stops heating, entering water electromagnetic valve (8) conducting water inlet, because boiling water is rapid, of short duration from the process that water boiling pot (2) is pressed into insulation boiled water tank (11), and the water inlet that entering water electromagnetic valve (8) action is connected lags behind because of the deferred action (effect of capacitor C 3) that designs in the circuit, so unboiled water can not sneaked into insulation boiled water tank (11).After treating that the interior liquid level of water boiling pot (2) rises to desired location, entering water electromagnetic valve (8) disconnects, electrothermal tube (1) conducting, repeat the process of aforementioned heating, setting-out again, water in insulation boiled water tank (11) floats magnetic force float (12) and causes tongue tube (14) conducting and disconnect electrothermal tube (1) and conducting PTC heater element (16) constant temperature that begins to generate heat, at this moment, whole boiling water machine is in drink state fully.When taking boiling water, the magnetic force float (12) in the insulation boiled water tank (11) descends with liquid level, and tongue tube (14) disconnects and makes electrothermal tube (1) connection and disconnect PTC heater element (16), and this machine repeats aforementioned work to boil water again to being equipped with the drink state.

When the running water inner pipe water pressure drops to the hydraulic pressure that water pressure safety switch (9) sets, water pressure safety switch (9) action and cut off the complete machine power supply, thus electrical equipment often leaves when avoiding lack of water, the situation of electrothermal tube (1) dry combustion method occurs.

The utility model is simple in structure, and cost is low, and drinking water is guaranteed the boiling sterilization and avoid through repeatedly boiling that health and energy-conservation can provide hot boiling water and cold water, and is convenient and practical.
