In cold source channel in exchanger 12, the normal-temperature water in water tank 11 is pumped into heating device 13 and dynamically add by the first water pump 15
Heat, the hot water after heating immediately enters the heat source passages of heat exchanger 12 by the first entrance 121 of heat exchanger 12, with cold source
Normal-temperature water in channel carries out heat exchange cooling, and the warm water that generating directly to drink is flowed out by tap, and whole process is not store
Warm water is deposited, tap just starts to be heated immediately, a series of actions that cools down carries out production warm water with opening, and has prevented bacterium
Growth problems, ensure that the quality of drinking water.
It is preferred that heating device 13 is electric heater unit, dynamic quickly heating, heating device 13 can be carried out to the water flowed through
In do not store hot water, can be to avoid the growth of bacterium.
When user uses water dispenser, it is possible to which the warm water come out from heat exchanger 12 is excessively high or too low, is not suitable for
It directly drinks, water tank 11 further includes the second water return outlet 114, the pipe between the first outlet 123 and tap 14 of heat exchanger 12
Triple valve 17 is provided in road, the entrance of triple valve 17 is connect with the first outlet 123 of heat exchanger 12, and triple valve 17 is wherein
One outlet is connect with tap 14, and in addition an outlet is connect with the second water return outlet 114 of water tank 11.When the temperature of warm water is not suitable for
When, it can be with switching three-way valve 17, so that the water after the heat exchange that heat exchanger 12 is flowed out flows back into water by the second water return outlet 114
In case 11, prevents from scalding or other are happened.
Triple valve 17 is preferably solenoid valve, is set in the pipeline between the first outlet 123 and triple valve 17 of heat exchanger 12
It is equipped with the first temperature sensor 18, solenoid valve and the first temperature sensor 18 are connect with control module respectively, the first temperature sensing
Device 18 is used to detect the temperature of the water outlet of the first outlet 123 of heat exchanger 12, and is sent to control module, due to heat exchanger
12 first outlet 123 is connect with tap 14, and therefore, temperature measured by the first temperature sensor 18 is close from tap stream
The temperature of water outlet, control module pass through the temperature value for judging the first temperature sensor 18 feedback, control each branch of triple valve 17
On state, for example, if the first temperature sensor 18 feedback temperature value be located at setting within the scope of, control module
The pipeline controlled between the first outlet 123 and tap of heat exchanger 12 is connected, and user can normally connect drinking water, if first
The temperature value that temperature sensor 18 is fed back is located at except the range of setting, if leaving water temperature is excessively high or too low, control module control
Pipeline between the first outlet 123 of heat exchanger 12 and the second water return outlet 114 of water tank 11 is connected, between tap
Pipeline disconnects, and can prevent that temperature is excessively high to lead to scald or temperature is too low gives up wasting situation by user, from
The water that the first outlet 123 of heat exchanger 12 goes out is returned in water tank by the second water return outlet 114, can avoid water resource waste.
It is preferred that the first water pump 15 or the second water pump 16 are the controllable variable frequency pump of frequency, can also both be variable frequency pump, water
Second temperature sensor 19 is provided in case 11, second temperature sensor 19 is connect with control module.Second temperature sensor 19
It is different according to the water temperature in water tank 11 for detecting the water temperature in water tank 11, after feeding back to control module, control module control the
One water pump 15 or the second water pump 16 go out different flows, in order to which water outlet comes out 45 degree needed.Such as the water temperature in water tank 11
When being 10 degree, 15 flow of the first water pump is 200ml/min, when the water temperature in water tank 11 is 20 degree, frequency conversion pump discharge 700ml/
Min, when the water temperature in water tank 11 is 30 degree, frequency conversion pump discharge is 1400ml/min, therefore adapts to Various Seasonal difference room temperature
Water temperature, the warm water for making out is in the range of being suitble to straight drink for 45 degree or so.
Heat exchanger 12 preferably uses shell-and-tube exchanger in the present embodiment, as shown in Fig. 2, shell-and-tube exchanger packet
The inner tube 12b for including shell 12a and being arranged in shell 12a forms shell side between the inner wall of shell 12a and the outer wall of inner tube, interior
The inside of pipe forms tube side, and first entrance 121 and first outlet 123 are connected to the both ends of tube side, and tube side corresponds to heat exchange
The heat source passages of device, shell side correspond to the cold source channel of heat exchanger, and second entrance 122 and second outlet 124 are connected to shell
The both ends of journey.Hot water after heating enters the tube side of heat exchanger 12 by the first entrance 121 of heat exchanger 12, and is located at shell
Normal-temperature water in journey carries out heat exchange cooling, and this programme carries out the water flowed through first with heating device 13 to be heated to higher temperature
Degree, plays the role of sterilization, then cools down through over-heat-exchanger 12, reaches the temperature for being suitble to directly drink, and whole process only needs
Want several seconds, rapid and convenient.
In order to improve heat exchange efficiency, so that high-temperature water is reduced to 45 degree or so in a short period of time, in the application preferably
Inner tube 12b includes several, and the both ends of inner tube 12b pass through two end plates respectively and the inner wall sealing of shell 12a is fixed, and is located at upper
The end plate of side is upper head plate 12c, and underlying end plate is bottom plate 12d, is enclosed between upper head plate 12c and the inner wall of shell 12a
At confluence chamber, surround splitter cavity between bottom plate 12d and the inner wall of shell 12a, the both ends of inner tube 12b respectively with confluence chamber and divide
Chamber connection is flowed, first entrance 121 is connected to splitter cavity, and first outlet 123 is connected to confluence chamber, and the hot water after heating is handed over by heat
The first entrance 121 of parallel operation 12 initially enters splitter cavity, separately flow into each inner tube 12b, during flowing through
It exchanges heat, by increasing the quantity of inner tube 12b, heat exchange area can be increased, and then heat exchange efficiency can be improved, flow through inner tube
The water of 12b enters confluence chamber and converges, and then flows out through first outlet 123.By being arranged first entrance 121 in bottom,
The setting of first outlet 123 is at top, and hot water is during entering inner tube, the gradually uplink under the pressure effect of water, the weight with water
Power is contrary, conducive to the air in the second heat exchanger channels of discharge, furthermore, it is possible to extend time of the hot water in inner tube, extends
It exchanges heat action time, and then heat exchange efficiency can be improved.
Since splitter cavity and confluence chamber are located at the both ends of shell 12a, it is therefore preferable that first entrance 121 and first
Outlet 123 is located at the both ends of shell 12a, and second entrance 122 and second outlet 124 can be formed in shell 12a's
On side wall.
By the way that second entrance 122 to be arranged in the top of shell, second outlet 124 is arranged in the lower part of shell, tube side and
The flow direction of liquid in shell side is on the contrary, make heat exchange more abundant.
Water tank 11 is open-type cistern, and water tank 11 further includes water purification entrance, and water tank 11 connects water purification by water purification entrance and sets
Standby, the water purification of purifier preparation is input in water tank 11, improves the quality of drinking water.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made in the essential scope of the utility model,
It should also belong to the protection scope of the utility model.
