In the present invention, in specific implementation, installation (such as bonding) has at least one layer of insulating layer on the outside of hot water reservoir 2.
For the present invention, it should be noted that household-tap water heating equipment 1, can for it is existing any one can be to water
It is heated, and it is made to be heated to the device of boiling point (such as 100 degrees Celsius), for example, existing drinking water water heater passes through
Heating tube or heating coil can heat the water of input, then output outward.
In specific implementation, household-tap water heating equipment 1 can be using the routine of Shenyang En Teng electric heating Science and Technology Ltd. production
Electric heater, can be by the tap water heating of room temperature at boiled water.
In the present invention, it should be noted that household-tap water heating equipment 1, for will from the first tap water connecting tube 10,
Not up to 100 degree of water of the first heat exchange coil 31 and the second heat exchange coil 32, is heated and is warming up to 100 degree, water temperature reaches
After 100 degree, boiled water is transported to hot water reservoir 2；
Hot water reservoir 2, for storing the boiled water from household-tap water heating equipment 1, user can take pipe 8 by hot water
Boiled water is obtained, when hot water reaches the rated capacity of hot water reservoir 2, hot water can be transported in water tank 18；Boiled water exists
It exchanges heat in water tank 18 with the tap water in the second heat exchange coil 32, the water temperature in water tank 18 obtains to a certain extent
On cooling, the hot water after cooling flows to the first heat exchange coil 31, while the tap water in the second heat exchange coil 32 has obtained one
Determine the heating in degree, and is transported to household-tap water heating equipment 1；
The liquid refrigerant of low-temp low-pressure in evaporator 3 absorbs the heat of hot water in third heat exchange coil 33, becomes high
Then the gaseous refrigerant of warm low pressure flows to compressor 5, compressor 5 pressurizes to the gaseous refrigerant of high-temperature low-pressure, so that it becomes
Then the gaseous refrigerant of high temperature and pressure flows to and carries out condensation heat release in condenser 4, become the liquid refrigerant of cryogenic high pressure,
And throttling set 6 is flowed to, heat is delivered to the first heat exchange coil, the tap water in 31, and tap water heating is transported to originally
In hot-water heating system 1, cryogenic high pressure liquid refrigerant is handled the liquid refrigerant for low-temp low-pressure and flows to steaming by throttling set 6
Send out device 3；Hot water in third heat exchange coil 33, the drinking water can directly to drink that cools down, which is transported to, drinks water storage bin 7
Interior, user can be taken pipe 9 by drinking water and be taken.
Compared with prior art, device for preparing drinking water provided by the invention, by being mounted on two tap water connections
Guan Shang absorbs the energy of hot water in water tank 18 first with the second heat exchange coil 32 being connected with the second tap water connecting tube,
Three heat exchange coils 33 are then fed to, and further by evaporator 3, condenser 4, compressor 5 and throttling set 6, especially
It is acted on by the evaporation endothermic of evaporator 3, significantly reduces the heat of hot water in third heat exchange coil 33, reduce third heat exchange coil
It the cooling time of hot water in 33, is then output to and drinks in water storage bin 7, at this time, since the temperature of water has significant drop
It is low, fast cooling is realized, people take pipe 9 by drinking the drinking water in water storage bin 7, can obtain temperature significant decrease
Water afterwards facilitates people that can drink in a relatively short period of time.
In addition, for the present invention, the heat discharged outward by condenser 4 can be heated and the second tap water connecting tube
The water in the first heat exchange coil 31 being connected, so that the tap water temperature in the first heat exchange coil 31 increases, then by the
The pressure conveying of two circulating pumps 20 acts on, and is conveyed to tap water heater and is heated.
Meanwhile for the present invention, the second heat exchange coil 32 being connected with the second tap water connecting tube is absorbing water tank
In 18 after the energy of hot water, after the tap water heating in the second heat exchange coil 32,19 pressure can also be pumped by first circulation
Conveying effect, is conveyed to tap water heater and is heated, therefore, the present invention can be to from the second tap water connecting tube
Water is preheated, and is then delivered in household-tap water heating equipment 1, so that the speed that household-tap water heating equipment 1 produces boiled water is promoted,
Save people's valuable time.Therefore, for the present invention, hot water (the i.e. water storage drawn from hot water reservoir 2 is not only reduced
Hot water in case 18) temperature, also use its heat, for next time heating save energy.
In conclusion compared with prior art, a kind of device for preparing drinking water provided by the invention, structure design department
It learns rationally, easily and reliably the tap water after heating rapidly can be cooled down, become available for the drink that people drink in time
With water, it is of great practical significance.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
