In fact, this embodiment may also be a modification on the basis of the first, third, or fourth embodiment.

In fig. 11, referring to the fourth embodiment, the first low-temperature water pipeline 241 and the second low-temperature water pipeline 242 may be the same low-temperature water pipeline 24, so that the water dispenser can output low-temperature water, hot water or normal-temperature purified water.

Compared with the second implementation mode, the embodiment of the invention has the advantages that the water dispenser further comprises a second energy storage heat exchanger, the second energy storage heat exchanger comprises a third heat exchange tube, a heat storage material and a heating element, namely, the water to be heated is subjected to heat exchange with the heat storage material through the third heat exchanger, and the water to be heated is heated through the phase change of the heat storage material, so that the water dispenser can output large-flow hot water according to the requirements of users, the water dispenser can output low-temperature water or hot water, and various drinking water requirements of different users are met.

A sixth embodiment of the present invention relates to a water dispenser. The sixth embodiment is an improvement of the fifth embodiment, and the main improvement is that: in the sixth embodiment of the present invention, as shown in fig. 12, the water dispenser further includes an instant heating device 81 electrically connected to the controller 1.

In this embodiment, the instant heating device 81 is configured to instantly heat the first hot water output by the third heat exchanging pipe 81 into the second hot water according to an instant heating instruction of the controller 1.

Preferably, in this embodiment, the water dispenser further includes a temperature detector 82 electrically connected to the controller 1 and configured to detect the temperature of the second hot water, and the controller 1 is further configured to determine whether the temperature of the second hot water is within a preset temperature range, and generate the adjustment instruction. The preset temperature range may be set by a user or before factory shipment, and the setting manner of the preset temperature range is not limited in any way in this embodiment.

In one example, the temperature detector 82 may be a thermistor (NTC), a temperature sensor, etc., but is not limited thereto, and the embodiment does not set any limit to the specific type of the first temperature detector 82.

Optionally, in this embodiment, as shown in fig. 13, the water supply module 2 further includes an electric water mixing valve 91 and a cool boiled water path 92, where the electric water mixing valve 91 is used to communicate the first energy storage heat exchanger 3 with the cool boiled water path 92, and communicate the instant heating device 81 with the cool boiled water path 92, that is, the cool boiled water path 92 is used to output the cool boiled water after mixing the low-temperature water and the second hot water; in addition, the electric mixing valve 91 may output low-temperature water or second hot water according to a user instruction. In this embodiment, when receiving the indication of the cool boiled water, the controller 1 controls the cool boiled water pipeline 92 to output the cool boiled water, that is, the water dispenser can output low-temperature water, the second hot water or the cool boiled water, thereby satisfying various requirements of users.

In one example, when the electric mixing valve 91 outputs the cool boiled water, the temperature of the output cool boiled water is also detected by the temperature detector 93, and when the temperature is higher than the maximum boundary value of the set temperature range, the electric mixing valve 91 adjusts the flow rate of the low-temperature water to be larger and the flow rate of the second hot water to be smaller until the temperature of the cool boiled water is within the set temperature range; when the temperature is lower than the minimum boundary value of the set temperature range, the electric water mixing valve 91 increases the water flow of the second hot water and decreases the water flow of the low-temperature water until the temperature of the cold boiled water is within the set temperature range; the set temperature range may be set by a user in advance, or may be set before shipment. In this embodiment, the temperature of the cool boiled water output by the electric water mixing valve 91 is detected, and the mixing ratio of the low-temperature water and the second hot water is adjusted according to the temperature, so that the temperature of the cool boiled water meets the requirements of the user.

In fact, as shown in fig. 14, the present embodiment may also be a solution based on the fourth embodiment, in which the water supply module 2 further includes a hot water pipe 26 connected to the instant heating device 81. The first water path switching valve 251 and the second water path switching valve 252 are specifically configured to communicate the filtering device 6 with the low-temperature water pipeline 24, or communicate the filtering device 6 with the normal-temperature water pipeline 23, or communicate the filtering device 6 with the hot water pipeline 26 according to a switching instruction of the controller 1, and the instant heating device 81 is configured to heat the water to be heated filtered by the filtering device 6.

In fact, this embodiment may also be the solution based on the first, second, or third embodiment.

Compared with the fifth embodiment, the water dispenser further comprises an instant heating device, namely, in the embodiment of the invention, the water to be heated is preheated by the latent heat of the heat storage material, and then the water heated by the heat storage material is heated by the instant heating device in an instant manner, so that the water dispenser further outputs hot water with higher temperature, and the instant heating device can realize accurate temperature control on the second hot water, so that the water dispenser further outputs high-temperature large-flow normal-temperature purified water, low-temperature water or the second hot water.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
