Problems solved by technology

The main problem is: the heater is located on one side of the water tank, and the heating is realized by the heat transfer between the water and the water. If it is high for a long time, the heater is prone to scaling, which will reduce the thermal efficiency of the heater and shorten the service life. The cold water in the outlet pipe, and then the hot water problem

Embodiment 1

[0013] Please read figure 1 , The solar water heater includes a shell 3, an insulation layer 2, an inner tank 1, a heat collector and a bracket, one side of the inner tank 1 is provided with a water inlet pipe 11, and the other side of the inner tank 1 is provided with a water outlet pipe 12 and a heater 4, and the outlet pipe 12 is connected with a water valve 13, and one side of the liner 1 is provided with a circulating water inlet 6, and the circulating water inlet 6 is connected with a circulating water pump 8 through a circulating pipe 7, and the circulating water pump 8 is connected to the circulating water outlet 5 through the circulating pipe 7. In addition, a normally open solenoid valve 10 can be provided between the circulating water inlet 6 and the circulating water pump 8, and a three-way port is provided on the circulating pipe 7 between the circulating water pump 8 and the normally open solenoid valve 10, and the three-way port passes through the return pipe 9 ...

Embodiment 2

[0015] Please read figure 2 , figure 2 It is an embodiment of the present invention, and the water tank is a vertical structural schematic diagram, and its structure and connection method are the same as those of the first embodiment.

[0016] When the present invention is in use, the circulating water pump 8 is connected with the circuit of the heater 4 to realize synchronous work or the circulating water pump 8 intermittently works; Synchronous work is realized through delayer control.

[0017] When the water temperature of the solar water heater is low on cloudy and rainy days, the heater 4 of the solar water heater is energized, the heater 4 emits heat energy to transfer to the water, and the circulating water pump 8 is started synchronously, and the hot water enters the circulating pipe 7 from the circulating water outlet 5 and passes through the circulating water inlet 6 It flows into the inner tank 1, and circulates the hot water at both ends of the inner tank 1, so...

Abstract

The invention relates to a solar water heater with rapid and even heating and a dynamic heating method thereof, and comprises an outer shell, a thermal insulation layer, an inner liner, a heat collector and a support. One side of the inner liner is provided with a water inlet pipe, the other side of the inner liner is provided with a water outlet pipe and a heater, a valve is connected on the water outlet pipe, one side of the inner liner is provided with a circulating water inlet, the circulating water inlet is connected with a circulating water pump by a circulating pipe, and the circulating water pump is connected on a circulating water outlet by the circulating pipe. The solar water heater carries out the circulating promotion by the circulating water pump with the tiny power consumption, the distribution of the hot water in the inner liner is even, the water temperature of the outlet water has no temperature difference, thus greatly improving the comfort of shower; the solar water heater can carry out the rapid and even heating to obtain the hot water, which is further characterized by long service life of the heater, short heating time, high efficiency and simple structure due to the reduction of the generation of water scale of the heater.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and relates to a fast and uniform solar water heater and a dynamic heating method thereof. Background technique [0002] With the improvement of people's living standards, solar water heaters have entered thousands of households. Hot water is widely used in bathing, washing hands, laundry, dishes, vegetables, etc., especially in winter, the amount of hot water is large, which makes solar water heaters The design capacity of the water tank is getting larger and longer, and the water tank is getting longer and longer, which puts forward higher requirements for the water temperature balance and heating speed in the heating process. At present, for large-capacity solar water heaters, whether using a heat pump heat exchanger or an electric heating tube as a heater for auxiliary heating in cloudy and rainy days, the water temperature needs to be set before use. Power cut off to stop heating to g...
