In one embodiment, a cool and boiled water supply system is provided and is suitable for equipment such as a water purifying and drinking machine, a water purifier and a water dispenser. As shown in fig. 1, the water supply system for the cool boiled water comprises a parameter acquisition device, a water supply device 100, a heating device 200, a heat exchange device 300 and a control device 400, wherein the heating device 200 is connected with the water supply device 100 and the heat exchange device 300, and the control device 400 is connected with the parameter acquisition device, the water supply device 100, the heating device 200 and the heat exchange device 300; the water supply device 100 is used for providing water source to the heating device 200, the heating device 200 is used for heating water to enable the water to reach a set heating temperature and then delivering the water to the heat exchange device 300, and the heat exchange device 300 is used for carrying out heat exchange and cooling on the received water; the parameter acquisition device is used for acquiring waterway data and sending the waterway data to the control device 400, and the control device 400 is used for carrying out parameter adjustment on the water supply device 100 and the heating device 200 according to the target water outlet temperature when the waterway parameters accord with the preset water taking starting conditions, so that the cooled boiled water temperature output by the heat exchange device 300 is matched with the target water outlet temperature. Wherein, the heating device 200 can heat the water to above 90 ℃ to boil the water. For convenience of understanding, the cold boiled water supply system applied to the water purifying drinking machine is explained as an example.

Specifically, the water supply device 100 receives raw water, provides normal-temperature purified water required for drinking to the heating device 200, and also provides cooling liquid to the heat exchange device 300 for heat exchange and cooling. The specific structure of the water supply apparatus 100 may be different depending on the quality of raw water. When the raw water is drinking water, the water supply device 100 may be a non-purification system, and the normal-temperature purified water is transported from the water outlet end of the water supply device 100 to the water inlet end of the heating device 200 only by a transportation device, such as a pressure stabilizing pump, or the heat-exchange low-temperature water is transported to the heat-exchange water inlet of the heat exchange device 300; when the raw water quality is non-drinking water quality, the water supply device 100 may have a corresponding purification system to purify the raw water quality to meet the drinking standard, and the normal temperature outlet water of the purification system is input to the water inlet end of the heating device 200 through the conveying device or is used as the heat exchange low temperature water source of the heat exchange device 300.

The heating device 200 may specifically adopt a power-adjustable heating element, which may be a PTC (Positive Temperature Coefficient) heating element, a rare earth thick film heating element, or a metal heating tube, etc., and the purified water contacting the heating element is heated and boiled by heating. The heating power of the heating element is controlled and adjusted by the control device 400 according to the detected parameters, and the boiled purified water is input into the purified water inlet end of the heat exchange device 300 from the water outlet end of the heating element.

The heat exchange device 300 may specifically adopt a heat exchanger or other sleeve heat exchange structure devices, a purified water inlet end of the heat exchange device 300 is connected to the heating device 200, and a purified water outlet end of the heat exchange device 300 may be connected to the water outlet nozzle 500. The heat exchange water inlet and the heat exchange water outlet of the heat exchange device 300 are connected to the water supply device 100. The heat exchanger 300 exchanges heat with the boiled purified water heated by the heater 200 by the cooling liquid provided by the water supply device 100 to cool the boiled water, and the cooled boiled water flows out from the water outlet 500. Wherein, combining the heating element and the heat exchanger, the temperature is reduced immediately after the water is boiled, and the instant preparation of the boiled water is realized.

The Control device 400 can adopt a Control mainboard, a Central Processing Unit (CPU), a Micro Control Unit (MCU) and other devices can be set on the Control mainboard, a user can set a target outlet water temperature through an interaction device according to the user's own needs, the interaction device sends the target outlet water temperature to the Control device 400 for storage, and the interaction device can be a key circuit or a touch screen. The user may also send the target outlet water temperature to the control device 400 for storage through a mobile phone, a remote controller, or other end devices.

After the target outlet water temperature is set, the user can also send a cool boiled water taking signal to the control device 400 through the terminal equipment, and the control device 400 starts to perform the cool boiled water preparation operation after receiving the cool boiled water taking signal. Specifically, the parameter acquiring device may include sensors disposed at the water supply device 100 and the heating device 200 to detect parameters of water level, water temperature, and the like. In addition, the parameter collecting device may further include a temperature sensor disposed at the clean water outlet end of the heat exchanging device 300 or the water outlet nozzle 500 to monitor the actual outlet water temperature. The control device 400 analyzes whether the collected water path data meets the preset water intake starting condition or not, and when the water intake starting condition is met, the target water outlet temperature and the collected water path data are combined to adjust the output water flow of the water supply device 100 and the heating power of the heating device 200, so that the heating device 200 heats the purified water, the purified water reaching the heating temperature is obtained and is conveyed to the heat exchange device 300, then the heat exchange device 300 performs heat exchange cooling on the boiled purified water, cool boiled water with the temperature matched with the target water outlet temperature is obtained, and finally the cooled boiled water flows out of the water outlet nozzle 500 for users to use. In addition, the control device 400 may perform synchronous/asynchronous parameter adjustment of the water supply device 100 and the heating device 200.

The control device 400 may also pre-store the corresponding relationship between the purified water temperature, the target effluent temperature, and the heating temperature, and after the purified water temperature and the target effluent temperature are determined, the control device 400 may directly determine the heating temperature. The temperature of the cool boiled water is matched with the target water outlet temperature, the temperature of the cool boiled water can be the same as the target water outlet temperature, and the difference value of the temperature of the cool boiled water and the target water outlet temperature can be within an allowable error range.

In addition, when the cool boiled water supply system is applied to other devices such as a water purifier and a water dispenser, the control device 400 may only detect the water temperature or the water flow, and when the water temperature or the water flow meets the requirement of the corresponding threshold, the water intake starting condition may be considered to be met.

When the waterway parameters meet the preset water intake starting conditions, the control device 400 adjusts the parameters of the water supply device 100 and the heating device 200 according to the target water outlet temperature, so that the cooled and boiled water temperature output by the heat exchange device 300 is matched with the target water outlet temperature.

When the user sends a new target outlet water temperature to the control device 400, the control device 400 may obtain a new heating temperature, and adjust the current heating parameter of the heating device 200 according to the temperature difference between the new heating temperature and the purified water temperature and the ratio of the temperature difference between the previous heating temperature and the purified water temperature, so that the heat exchange device 300 outputs cool boiled water with the output temperature matched with the updated target outlet water temperature.

The control device 400 may specifically adjust the output flow rate of the raw water pump 104 according to the updated target outlet water temperature, for example, when the updated target outlet water temperature is higher than the original target outlet water temperature, the output flow rate of the raw water pump 104 is decreased; when the updated target outlet water temperature is lower than the original target outlet water temperature, the output flow of the raw water pump 104 is increased. The fine adjustment correction can also be achieved by adjusting the output flow rate of the raw water pump 104 according to the updated target outlet water temperature, so that the output temperature of the heat exchange device 300 is cool and boiled with the target outlet water temperature.

It should be noted that the specific structure of the cool boiled water supply system may be different according to different application scenarios of the cool boiled water supply system. For example, when the cold boiled water supply system is applied to a water purifier, the water supply device 100 may not include the purified water tank 101, directly filter the incoming water source, and deliver the filtered purified water to the heating device 200.
