Embodiment 1

[0042] image 3 , Figure 4 It is a structural schematic diagram of Embodiment 1 of the high-efficiency continuous solar hot water supply system of the present invention. The device includes: a solar water heater 30 , a hot water incubator 40 , and a control device 50 . In order to overcome the deficiency that the existing technology utilizes cold tap water to push out the hot water that has been sun-dried to a certain temperature in the sun-drying box and enters the hot water incubator. Described solar water heater 30 comprises at least one drying box series group (such as Figure 5 shown); and each of the hot water drying boxes 31, 32, ..., 3n is equipped with a temperature and water level sensor 51 connected to the control device, and each hot water drying box 31, 32, ... A solenoid valve 52 controlled by a control device 50 is provided on the series pipeline of , 3n. According to the local air temperature, the drying temperatures of the hot water drying boxes 31, 32, .....

Embodiment 2

[0050] Figure 7 It is a three-dimensional schematic diagram of Embodiment 3 of the high-efficiency continuous solar hot water supply system of the present invention. In this embodiment, a high-level water tank 100 is provided between the water storage pre-drying box 60 and the series group of drying boxes. The side of the high-level water tank 100 is provided with a water inlet pipe 110, and the bottom is provided with a water outlet pipe 120. The water outlet pipe 62 of the water storage pre-drying box 60 is connected to the water inlet pipe 110 of the high-level water tank through the water pump 69, and the water outlet pipe 120 of the high-level water tank is connected to each sun-drying box series group through the water inlet electromagnetic valve 64.

[0051] The function of the high-level water tank 100 is to increase the pressure of the water flowing into the series groups of sunning boxes. When the sub-water inlet solenoid valve 64 is opened, the water can quickly fl...

Embodiment 3

[0053] Figure 8 It is a schematic diagram of the solar water heater of Embodiment 3 of the high-efficiency continuous solar hot water supply system of the present invention. The difference between this embodiment and Embodiment 1 is that the connecting structures between the series connected hot water drying tanks and the hot water drying tanks that constitute the solar water heater 30' are different. Figure 8 It can be seen that the solar water heater 30' in this embodiment also includes at least one sunning box series group composed of a plurality of hot water drying boxes 31, 32, ..., 3n, and only The last hot water drying box 3n is provided with a temperature and water level sensor 51 connected to the control device, and the pipelines of each series-connected drying box are provided with a check valve 90 instead of an electromagnetic valve.

[0054] Its working process is as follows:

[0055] The control device controls the sub-inlet electromagnetic valve 64 on the wat...

Abstract

The invention relates to a solar energy hot water device, in particular to a low-cost and high-efficiency continuous solar energy hot water supplying system used for centralized heating of big guest houses, hospitals and district residential buildings. The high-efficiency continuous solar energy hot water supplying system comprises a solar energy water heater, a hot water insulation case and a control device, wherein the solar energy water heater at least comprises a sun-cured case serial group formed by a plurality of hot water sun-cured cases, a temperature and water level sensor connected with the control device is arranged in each hot water sun-cured case, and a valve is arranged on a serial pipeline. The invention has the advantages that the cost is low, the heat efficiency is high, and hot water in the sun-cured cases is pumped into the insulation water tank for standby usage when the water temperature in the sun-cured cases reaches the maximum setting temperature (such as 50 DEG C), thereby a certain amount of high-temperature hot water can be ensured to enter the insulation case.

Description

technical field [0001] The invention relates to a solar water heating device, in particular to a low-cost, high-efficiency and continuous solar water heating supply system for centralized heating of large hotels, hospitals, and residential buildings in residential areas. Background technique [0002] Solar hot water is the field with the most mature technology, the most widely used and the fastest industrialization development in the utilization of solar heat. General requirements for solar water heaters: 1. High utilization rate of sunlight and heat; 2. Easy to use, automatic system control, stable heat supply all year round; 3. Low price and small investment. [0003] Patent No. 97122306.8 provides a solar hot water drying device that uses sunlight to heat cold water to a predetermined temperature from a hot water drying box, and then automatically sends hot water into the hot water insulation box by the pressure of tap water. Its structure is as follows: figure 1 As show...
