according to the range of the temperature reduction range of the hot water outlet, calculating the numerical range of heat energy to be exchanged between the hot water and the cold water in the hot water outlet pipe 2;
and calculating the numerical range of the pipeline surface area of the hot water outlet pipe 2 in the water heat-dissipation heat-exchange slow flow box 4 according to the heat energy to be exchanged.
In this embodiment, if the temperature drop range of the hot water outlet is between 5 ℃ and 15 ℃, the temperature change of 5 ℃ is taken as the lower limit of the heat energy that the hot water and the cold water in the hot water outlet pipe 2 should exchange, and the temperature change of 15 ℃ is taken as the upper limit of the heat energy that the hot water and the cold water in the hot water outlet pipe 2 should exchange, the heat energy that the hot water and the cold water in the hot water outlet pipe 2 should exchange can be calculated by the following formula:
Q＝CM(t2-t1)；
wherein, C is the quality of hot water in the heat exchange section 22 of the hot water outlet pipe 2, M is the specific heat of an object, t2 is the temperature of the hot water in the hot water outlet pipe 2 before heat exchange, and t1 is the temperature of the hot water in the outlet pipe after heat exchange.
After the numerical range of the heat energy to be exchanged between the hot water and the cold water in the hot water outlet pipe 2 is obtained, the numerical range of the pipeline surface area of the hot water outlet pipe 2 in the water heat dissipation and exchange buffer box 4 can be calculated according to the following formula:
Q＝KS(T2-T1)；
wherein K is the heat exchange coefficient, S is the pipeline surface area of the hot water outlet pipe 2 in the heat-dissipation heat-exchange slow flow box 4, T2 is the temperature of the hot water in the hot water outlet pipe 2 before heat exchange, and T1 is the temperature of the cold water inlet before heat exchange.
And selecting a proper pipeline surface area of the hot water outlet pipe 2 in the water heat-dissipation heat-exchange slow flow box 4 according to the calculation result.
In the above calculation method, the maximum hot water temperature of the water heater is usually calculated during calculation, after the surface area of the heat exchange section 22 is determined, when the hot water temperature in the hot water outlet pipe 2 is reduced to a lower temperature before heat exchange, the heat exchange area and the heat exchange coefficient are fixed, and the temperature difference between the cold water inlet and the hot water is reduced, so that the heat exchange amount between the cold water inlet and the hot water outlet is synchronously reduced, and therefore, even if the hot water temperature in the liner 1 is lower, the hot water outlet cannot be rapidly reduced under the influence of the water-dispersing heat exchange slow flow box 4, the fluctuation of the water outlet temperature is stabilized, and the temperature stability of the hot water output of the water heater is ensured.

In this embodiment, the heat exchange section 22 is a coil structure, and the coil structure makes the cold water in the water-dispersing heat exchange slow flow box 4 fully contact with the hot water outlet pipe 2, and facilitates adjustment of the pipe area of the heat exchange section 22, preferably, the coil of the heat exchange section 22 is preferably 1-2 circles.
The tenth embodiment of the invention provides an energy-regulating and recycling type efficient water heater, and on the basis of any one of the above embodiments, as shown in fig. 1 to 2, the energy-regulating and recycling type efficient water heater further comprises an electric heating tube 5, and the water-dispersing heat-exchanging slow-flow box 4 is fixedly connected with the electric heating tube 5 and/or the inner container 1.
In the embodiment, the electric heating tube 5 is used for heating the water in the liner 1, because the heat exchange capacity of the dispersed water heat exchange slow flow box 4 is increased along with the increase of the temperature difference, the output of ultra-high temperature hot water is inhibited, the heating of the electric heating tube 5 can be started at the first time when cold water enters the water tank, the heating time in the whole using process is increased, and the output of warm water of the whole water heater is improved; the maximum temperature which can be reached by hot water in the inner container 1 of the water heater can be increased, for example, the maximum temperature is set to 90 ℃, but in order to ensure the service life of the water heater, the temperature of 90 ℃ can be set to be a maximum heating mode, and when the maximum mode is started and is heated to 90 ℃, the normal heating mode of 75 ℃ is automatically and forcibly exited until the maximum heating mode is manually restarted.
Specifically, the maximum heating mode is set manually, and does not exceed 3 times per 24 hours.
