Abstract
The utility model relates to a domestic electric water heating device for shower, mainly composed of a housing, a water tank, electric heating pipes, a water-control contact switch, an alternating-current contactor and a power regulator. The utility model obtains hot water through two electric heating pipes connected in parallel and energized and heated in the water tank, the water-control contact switch controls the connection or disconnection of the electric heating pipes and a power supply through controlling the alternating-current contactor, and the power regulator is connected with one electric heating pipe in series to regulate heating power. The utility model has the advantages of fast heating speed and regulated heating power.
Description
The utility model relates to a kind of electric heater, especially family expenses shower electric heater.
At present, a kind of new-type family expenses shower electric heater on the market, its structure is made up of shell, water tank, electrothermal tube, water control contact switch and attaching plug.Wherein water tank is contained in the top in the shell, and the water tank end face is shaped on that water-in and water-out are chewed and all stretch out shell; An electrothermal tube that stretches in the water tank is installed in the water tank side; The water tank bottom surface has a through hole, and the water control contact switch is contained in this through hole and seals this through hole, and electrothermal tube is directly connected with the water control contact switch, but the water control contact switch is according to the water pressure conducting in the water tank or separate electric loop.This water heater is simple in structure, thermal efficiency height.But also have following deficiency in actual applications: promptly firing rate is slow and electric thermal power is non-adjustable.
The purpose of this utility model just provides the family expenses shower electric heater that a kind of firing rate is very fast and heating power is adjustable.
Technical solution of the present utility model is: family expenses shower electric heater has shell, water tank, electrothermal tube, water control contact switch, power governor, A.C. contactor, lead and attaching plug; Water tank is installed in the top in the shell, A.C. contactor and power governor are installed in the bottom in the shell, the electrothermal tube that stretches in the water tank is contained on the water tank side, the water tank bottom surface has a through hole, the water control contact switch is contained in this through hole and seals this through hole, but the water control contact switch is according to the water pressure conducting in the water tank or separate electric loop; Its special feature is: be equipped with two electrothermal tubes parallel with one another in the above-mentioned water tank, an electrothermal tube is by the direct incoming transport contactor of lead, another electrothermal tube earlier with incoming transport contactor again after power governor is connected, the another side of A.C. contactor links by lead and attaching plug, the control coil of A.C. contactor and water control contact switch are connected in series, and A.C. contactor is connected power supply or cut off the electricity supply is to be controlled by the water control contact switch.
The utility model is owing to assembled two electrothermal tubes, its electric thermal power increases, and can regulate the electric thermal power of an electrothermal tube by power governor, and the water control contact switch connects with the control coil of A.C. contactor, thus make its contact avoid electric thermal power increase influence.Therefore, it has the advantage of the very fast and adjustable power of firing rate.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing is a structural representation of the present utility model.
The utility model by shell (1), water tank (2), electrothermal tube (3), (12), water-control switch (5), attaching plug (7), (10) are chewed in water inlet, water outlet is chewed (11), A.C. contactor (8), power governor (9) and lead (4), (6), (13), (14) and formed.Water tank is installed in the bottom in the shell, the electrothermal tube that stretches in the water tank is contained on the water tank side, the water tank bottom surface has a through hole, and the water control contact switch is contained in this through hole and seals this through hole, but the water control contact switch is according to the water pressure conducting in the water tank or separate electric loop; Be equipped with two electrothermal tubes parallel with one another in the above-mentioned water tank, an electrothermal tube is by the direct incoming transport contactor of lead, another electrothermal tube earlier with incoming transport contactor again after power governor is connected, the another side of A.C. contactor links by lead and attaching plug, the control coil of A.C. contactor and water control contact switch are connected in series, and A.C. contactor is connected power supply or cut off the electricity supply is to be controlled by the water control contact switch.Chewing external water channel when water outlet closes and intakes that to chew external water channel open-minded, current are chewed through water inlet and are entered water tank and water level raises gradually, water pressure in the water tank also increases gradually, after two electrothermal tubes all are immersed in the water by water, water pressure in the water tank just can make water control contact switch closing contact and conducting A.C. contactor control coil electricity loop, so the electrical contacts closed and connection power supply on the A.C. contactor, just energising heating of electrothermal tube.Open water outlet then and chew external water channel, the just outflow from water outlet is chewed of heated hot water, water inlet is chewed then and can be continued to flow into cold water simultaneously.Firing rate can be regulated by power governor, because of needing an electrothermal tube heating at least, just can satisfy the adjusting needs so power governor is only controlled an electrothermal tube in actual applications.When two electrothermal tubes all during heating with full power, firing rate is obviously very fast.
