Description

The quick electric water-boiling device of card-scanning type

One, technical field

The utility model relates to a kind of electricallly heated water boiling vessels, the quick electric water-boiling device of a kind of specifically card-scanning type.

Two, background technology

Past, the street, enterprise and universities and colleges are in order to solve the problem of people's drinking water, be provided with tea furnace, utilize wooden carbon or coal to heat up water with the supply demand, development along with society, tea furnace is replaced by electrically heated boiler gradually, existing electric water-boiling device has conveniently, fast, practical advantage, and do not produce emission and help environmental sanitation, but open and close and do not measure or billing function because it is controlled by the people fully, can't realize consumption control accurately, particularly in each universities and colleges, using hot water all is to adopt toll administration, cause each boiler all must someone to keep an eye on, and, make it cause dispute in actual use easily owing to there be the inaccurate of metering of chargeing, more there is the human boiling water to clean rice bowl, mop, laundry, the serious waste energy.

Three, utility model content

1, goal of the invention: the utility model is in order to overcome the deficiencies in the prior art, provides a kind of place at public water to carry out unattended and the quick electric water-boiling device of card-scanning type that can the accurate billing water.

2, technical scheme: the quick electric water-boiling device of a kind of card-scanning type described in the utility model, comprise support, shell, cold water storage cistern, inner bag, electric heating tube, outlet pipe, water inlet pipe and circuit controller, described shell is rack-mount, cold water storage cistern is housed in the enclosure, inner bag and circuit controller, cold water storage cistern connects the water source by water inlet pipe and links to each other with inner bag by pipeline, in inner bag, be provided with electric heating tube by circuit controller control, outlet pipe is installed on the inner bag and stretches out shell, it is characterized in that: on shell, be provided with card reader, be provided with the magnetic valve that is opened and closed by card reader control on outlet pipe, card reader also is electrically connected with circuit controller.

Circuit controller comprises partial power and signal controlling two parts, and partial power is to connect AC relay, tongue tube and A.C. contactor by power supply respectively through controllable transformer, and AC relay links to each other with card reader again; The signal control part branch comprises that card reader one tunnel connects magnetic valve, another road connects electric heating tube through DC relay, Kick type temperature controller, A.C. contactor realizes adding thermal control, and tongue tube connects knob temperature controller, AC relay and electric heating tube realization preservation and controlling successively.

Running water is at first laid in cold water storage cistern through water inlet pipe, water when the water yield in the inner bag reduces in the cold water storage cistern injects inner bag with supplement consumed from the inner bag bottom, when using IC-card or magnetic card, water intaking person on card reader, carries out the operation of swiping the card the first time, card reader control magnetic valve is opened, hot water is flowed out by outlet pipe, when water intaking person carried out swiping the card the second time operation, card reader control closed electromagnetic valve was finished the process of once fetching water; The heater circuit (being that many heating tubes heat simultaneously) that the A.C. contactor of card reader control is meanwhile opened electric heating tube heats the cold water that replenishes into, when temperature reached the design temperature of Kick type temperature controller, A.C. contactor disconnected heater circuit and stops heating.In order in long-time unmanned water intaking process, to keep the water temperature in the inner bag, control the switching (i.e. a heating tube job) of AC relay realization to the thermal circuit of electric heating tube by the knob temperature controller that the temperature sensor unit is located on the inner bag; In addition, in order to prevent after cutting off the water, the inner bag water yield exhausts and situation that electric heater is still worked takes place, and also is provided with tongue tube on inner bag, and the operating circuit that cuts off electric heater in case the inner bag water yield is lower than the height of tongue tube stops heating process.

3, beneficial effect: the utility model has been installed the control system of swiping the card on the electric water-boiling device that constituent parts all generally uses, not only realized unattended, and can carry out reasonable and the water accurately that charges.It is specially adapted to universities, if the quick electric water-boiling device of card-scanning type is installed in each student dormitory, because it is deducted fees and calculates with the water yield all is to finish automatically, and accurate measurement, so can supply student's boiling water in 24 hours, and the boiling water room that need not like before on time school's appointment goes to fetch water, so both made things convenient for the student, economize the energy for school again, stopped waste.
