Referring to fig. 1, the warm water system in one embodiment of the present invention includes a control module, a water storage tank 100, a water pump 200, a heat exchanger 300, a heating module 400, and a warm water outlet line 510. The heat exchanger 300 includes a cold water line and a hot water line. The water outlet end of the water storage tank 100 is communicated with the cold water inlet of the heat exchanger 300 through the water pump 200. The heating module 400 is disposed between a cold water outlet of the heat exchanger 300 and a hot water inlet of the heat exchanger 300, and heats cold water. The hot water heated by the heating module 400 enters the heat exchanger 300 through the hot water inlet of the heat exchanger 300, and is changed into warm water after exchanging heat with the cold water in the cold water pipeline. The hot water outlet of the heat exchanger 300 is communicated with the warm boiled water outlet pipeline 510, and warm boiled water after heat exchange flows out from the warm boiled water outlet at the end of the warm boiled water outlet pipeline 510. Wherein, a heating body 110 and a first temperature detecting device 610 are provided in the water storage tank 100. The heating body 110 is used to heat water in the water storage tank 100.

The control module controls the heating body to heat the water in the water storage tank 100 to a preset water temperature, for example, 30 ℃ according to the first temperature detection device 610, and when the preset water temperature is reached, the heating body is closed, so that the water in the water storage tank is heated to be kept at the preset water temperature. The control system controls the water pump 200 according to the preset water temperature, and adjusts the flow rate of the water pump 200 according to a flow meter connected with the water pump 200. The water tank 100 discharges water with a constant temperature, and the water passes through the water pump 200, the heat exchanger 300, the heating module 400 and the warm water outlet pipe 510 in sequence at a constant flow rate.
In the warm boiled water system, the heat exchange is performed through the heat exchanger 300, so that the warm boiled water function is realized, and meanwhile, cold water in the heat exchanger 300 supplies water to the heating module 400 after absorbing heat, the water entering the heating module 400 is preheated, and the heat energy is fully utilized; through setting up the heating body at storage water tank 100, make the temperature of water in storage water tank 100 reach and predetermine the temperature, the water of constant temperature in storage water tank 100 like this passes through water pump 200, heat exchanger 300, heating module 400 with invariable velocity of flow in proper order, can ensure that hot water comes out the very stable warm boiled water of temperature after the heat exchange, can not fluctuate because of different seasons such as winter, summer and realize the accurate control of warm boiled water temperature.
In addition, the cold water outlet of the heat exchanger 300 is further provided with a second temperature detecting device 620 for detecting the temperature of the water before entering the heating module 400 and feeding back to the control module. The control module controls the heating module 400 according to the water temperature detected by the second temperature detecting device 620, and adjusts the heating power of the heating module 400, for example, when the water temperature is low, the power is increased, and when the water temperature is high, the power is decreased.
Further, a third temperature detection device 630 and a first switching valve 710 are disposed on the warm water outlet pipe 510. The first switching valve 710 is connected to the water storage tank 100 through the first switching pipe 520. The third temperature detecting means 630 is disposed between the first switching valve 710 and the hot water outlet of the heat exchanger 300, and the control module controls the switching of the switching valve according to the water temperature detected by the third temperature detecting means 630. When the water temperature detected by the third temperature detecting device 630 is the set warm boiled water temperature, the first switching valve 710 is communicated with the warm boiled water outlet, so that warm boiled water flows out from the warm boiled water outlet; when the water temperature detected by the third temperature detecting device 630 does not meet the set warm boiled water temperature, the control system controls the first switching valve 710 to switch the pipeline, so that the water in the warm boiled water pipeline flows into the water storage tank 100, and the pipeline is switched to allow the warm boiled water to flow out until the water temperature reaches the set warm boiled water temperature. Through the first switching valve 710 and the third temperature detecting device 630, the water which does not reach the temperature can be discharged to the water storage tank 100 again, and when the warm boiled water system does not perform heat exchange for a long time, the water is discharged to the water storage tank 100, so that the cold water is prevented from flowing out from the warm boiled water outlet at the beginning.
Furthermore, the warm water system further includes a second water outlet pipeline 530, and the second water outlet pipeline 530 is used for flowing out water with other temperatures, such as normal temperature water, water with different temperatures of 45 ℃ and 60 ℃. A second switching valve 720 is provided on a pipeline between the heating module 400 and the hot water outlet of the heat exchanger 300, the second switching valve 720 is communicated with the second water outlet pipeline 530 after switching, and when water with other temperature is required to be discharged, the second switching valve 720 is controlled to switch. In other embodiments, the second directional valve may be replaced by two control valves to achieve the same line switching function.
