Technical Field

[0001] This invention relates to the field of boiled water production technology, and more specifically, to a boiled water production system, a water purifier, and a boiled water production method. Background Technology

[0002] Against the backdrop of the booming health industry, consumer demand for household water purifiers is constantly expanding the boundaries of product value beyond water quality safety requirements, with product functions gradually shifting from safety to health and comfort. In addition to pure water products, products with a wide range of functions have emerged. Among them, the concept of boiled water (i.e., cooked water) is deeply rooted in consumers' minds and may become the next selling point for water purifiers.

[0003] Currently, the national standard only requires that hot water reach its boiling point within 200ml. Boiled water is produced by heating with an instant heating element. During the heating process, because the volume of cold water in the boiling water setting is too large, and the temperature of the boiled water setting must be controlled after the cold water is boiled first, some of the low-temperature water in the boiling water setting will be transferred to the boiled water setting. This results in the user getting cold water as the first cup of water, which significantly affects the promotion of the boiled water function and the actual user experience of the product. Summary of the Invention

[0066] The present invention provides a water purifier, including the above-mentioned boiled water production system.

[0067] This invention also provides a method for producing boiled water, applicable to the aforementioned boiled water production system. When the boiled water production system activates the zero-cold-water instant supply mode, the boiled water production method includes: obtaining the temperature of the cooled boiled water required by the user as a first temperature T1; obtaining the real-time temperature of the raw water in the water supply pipeline 2 of the boiled water production system as a second temperature T2; calculating the difference between the boiling point T0 of water and the second temperature T2 as a first temperature difference ΔT1; turning on the electric heating component 13 of the heat exchanger 1, and controlling the electric heating component 13 to operate at a first power P1 according to the first temperature difference ΔT1; calculating the water flow rate at the outlet of the water pump 22 of the boiled water production system according to the first power P1 and the first temperature difference ΔT1 as a first flow rate Q1, and controlling the water flow rate at the outlet of the water pump 22 to be the first flow rate Q1, so as to heat the water in the heat exchanger 1 to the first temperature T1.

[0068] For example, T1 = 55℃, T2 = 25℃, Q1 = 0.4L / min.

[0069] Before the boiled water production system starts the zero-cold-water instant supply mode, the boiled water production method of the present invention includes: when the user selects to take cooled boiled water at a first temperature T1, detecting the liquid level in the water tank 21 on the water supply pipeline 2; when the liquid level in the water tank 21 is greater than the preset low liquid level, obtaining the temperature of the water at the outlet of the heating component 31 as the third temperature T3; when the third temperature T3 is less than the first preset temperature, controlling the boiled water production system to start the zero-cold-water instant supply mode; wherein, the first temperature T1 is greater than the first preset temperature.

[0070] For example, T1 = 55℃, and the first preset temperature = 40℃.

[0071] When the third temperature T3 is greater than or equal to the first preset temperature, the boiled water production system is controlled to start the multi-temperature-segment boiled water supply mode.

[0072] For example, T1 = 55℃, T2 = 25℃, Q2 = 0.81L / min.

[0073] When the boiled water production system is in the zero-cold-water instant supply mode, the boiled water production method of the present invention further includes: acquiring the temperature of the water at the outlet of the water outlet pipe 4 in real time as the fourth temperature T4; when the fourth temperature T4 is equal to the first temperature T1, controlling the boiled water production system to switch from the zero-cold-water instant supply mode to the multi-temperature-segment boiled water supply mode.

[0075] In the step of calculating the water flow rate at the outlet of the water pump 22 of the boiled water production system based on the first temperature difference ΔT1 as the first flow rate Q1, the formula for calculating the first flow rate Q1 is 4187×ΔT1×Q1=P1×η1, where η1 is the heating efficiency of the electric heating component 13.

[0076] Specifically, η1 = 100%.

[0077] In the step of calculating the water flow rate at the outlet of the water pump 22 based on the second temperature difference ΔT2 as the second flow rate Q2, the formula for calculating the second flow rate Q2 is 4187×ΔT2×Q2=P2×η2, where η2 is the heating efficiency of the heating element 31.

[0078] Specifically, η2 = 90%.
