The instant heating purifying type water dispenser 10 includes a cabinet 11, a heater 12, a controller 13, and a heating water purifier 14.

The cabinet 11 is provided with an external water inlet 110, a water outlet nozzle 111, and a mounting groove 112 at the top of the cabinet 11.

The heater 12 is arranged in the inner cavity of the machine shell 11, and the heater 12 is provided with a water inlet pipe and a water outlet pipe.

The controller 13 is provided in the cabinet 11.

The heating water purifier 14 is detachably provided in the mounting groove 112, and the heating water purifier 14 includes a housing 140, a heating water softener 141, and a composite filter element 142.

The heating and water softening device 141 is detachably installed in the housing 140, and is provided with a water receiving port and a water pump 1410.

The composite filter element 142 is fixed in the housing 140 and is configured with a water inlet portion and a water outlet portion.

Wherein, the water receiving port is connected with the external water inlet 110, is connected with an external water source, heats the water in the heating water softener 141 to boiling, generates soft water and generates a water temperature signal, and the heating water softener 141 is in communication connection with the controller 13 and transmits the water temperature signal to the controller 13;

the water pump 1410 is connected to the water inlet unit and is in communication with the controller 13, and when the controller 13 receives a water temperature signal satisfying a condition, the water pump 1410 is controlled to pump soft water into the composite filter element 142 for filtering to generate pure water.

The water outlet portion is connected to the heater 12 and the water outlet nozzle 111 through a valve structure to selectively supply pure water to one of the heater 12 and the water outlet nozzle 111 through the valve structure.

The heater 12 is used to heat the received pure water, and supplies the heated pure water to the water outlet nozzle 111.

The instant heating and purifying type water dispenser 10 can be directly communicated with a municipal tap water pipeline. The instant heating purifying type water dispenser 10 includes a cabinet 11, a heater 12, a controller 13, and a heating water purifier 14. The external water inlet 110 of the housing 11 communicates with a municipal tap water pipe that supplies tap water to the instant heat-purifying water dispenser 10. Tap water enters the heating water purifier 14 from the external water inlet 110 to be heated and purified to generate pure water, and the pure water can be selectively delivered to one of the heater 12 and the water outlet nozzle 111 through the valve structure so as to be heated or directly drunk by people, and people can also drink the pure water heated by the heater 12. Wherein, in order to improve the service life of the instant heating purification type drinking machine 10, the heating water purifier 14 is detachably arranged in the casing 11, when the heating water purifier 14 is damaged or can not work normally, the maintainer of the instant heating purification type drinking machine 10 can install a new heating water purifier 14 in the casing 11 to continue the service life of the instant heating purification type drinking machine 10. In order to reduce the use cost of the heating water purifier 14, the heating water purifier 14 includes a housing 140, a heating water softener 141, and a composite filter element 142. After entering the heating water purifier 14, the tap water is first heated by the heating water softener 141 to precipitate calcium and magnesium ions in the tap water, so that the tap water becomes soft water, and when the heating water softener 141 detects the temperature of the tap water and transmits a water level signal to the controller 13, and when the controller 13 receives a water temperature signal satisfying a condition, for example, when the temperature of the tap water on the surface of the water temperature signal is 100 degrees celsius, the water suction pump 1410 is turned on. Soft water is pumped into the composite filter element 142 by a suction pump 1410 for filtration. It should be noted that, since tap water is first heated and softened, the filtering load of the composite filter element 142 is relatively small, which can effectively prolong the service life of the load filter element, thereby prolonging the replacement period of the load filter element. Meanwhile, the heating water softener 141 is detachably disposed in the housing 140, that is, a maintenance worker of the hot water purification type water dispenser 10 can periodically detach the heating water softener 141 to remove the scale in the heating water softener 141, thereby prolonging the service life of the heating water softener 141.

In this embodiment, the composite filter element 142 includes an activated carbon filter element 20 and a PP cotton filter element 21, and the activated carbon filter element 20 and the PP cotton filter element 21 are connected in series.

Wherein, the active carbon filter core 20 can be able to bear 300 degrees centigrade, so can directly carry the soft water that has just heated to the active carbon filter core 20 in, simultaneously, hot soft water flows in the active carbon filter core 20 simultaneously, can conduct the heat to the active carbon filter core 20 gradually, and to external radiation to reduce the temperature of soft water.

The soft water with reduced temperature safely enters the PP cotton filter element 21 for further heat dissipation treatment, and simultaneously plays a certain role in filtration.

The pure water filtered by the activated carbon filter element 20 and further subjected to heat dissipation treatment in the PP cotton filter element 21 can selectively enter the heater 12 or be directly discharged from the water outlet nozzle 111 according to the control of an operator on the controller 13, so as to adapt to the temperature for people to drink.

In this embodiment, the composite filter element 142 further includes a cooling temperature detector 22, a water pump 23, and an RO membrane filter element 24.

The activated carbon filter element 20, the PP cotton filter element 21, the cooling temperature detector 22, the water pump 23 and the RO membrane filter element 24 are connected in series.

Wherein, the instant heating purification type water dispenser 10 is powered on, and when in work, the free water is processed by the heating water purifier 14 to generate pure water with proper temperature.

When the controller 13 is not activated, i.e., there is no demand for drinking pure water at an appropriate temperature, the second electromagnetic valve 32 is closed and the first electromagnetic valve 31 is opened. Pure water with a proper temperature enters the heater 12 to be heated and stored, after the pure water is heated for a certain time, for example, 2 hours, the heated water is stored for a certain time, for example, 6 hours, and when people do not trigger the controller 13, that is, when the demand of drinking the pure water with a proper temperature and the heated water does not exist, the water in the heater 12 is discharged through the water discharge pipe, otherwise, when the demand of drinking the heated water exists, the controller 13 is triggered, and the third electromagnetic valve 33 is opened.

Similarly, when the instant purification type water dispenser 10 is in standby, if people need to drink pure water with a proper temperature, the controller 13 is triggered, water temporarily stored in the cooling temperature detector 22 is pumped into the RO membrane filter element 24 through the water pump 23, and then the second electromagnetic valve 32 is opened, so that pure water with a proper temperature is obtained.
