Hot water device and control method thereof, and preheating circulation system

Abstract

The embodiments of the present application provide a hot water device integrated with a soft water function, a control method thereof, and a preheating cycle system, wherein a method for controlling a preheat cycle of a hot water device is provided. A soft water water path and a bypass water path, each of which can be independently turned on or off, a preheating circulation pump located upstream or downstream of the soft water water path and the bypass water path, and a heat pump located downstream of the soft water water path and the bypass water path an exchanger; the softening water circuit is provided with a softening module for softening water; wherein, the preheating cycle control method includes: starting the preheating circulation pump, conducting the bypass water circuit to perform a preheating cycle; When the inlet water temperature of the hot water device increases to above the first predetermined temperature, the soft water circuit is turned on to perform a preheating cycle.

Description

technical field [0001] The application relates to the field of hot water devices, and in particular, to a hot water device, a control method thereof, and a preheating circulation system. Background technique [0002] At present, with the improvement of people's living standards, people's requirements for daily water use are becoming more and more strict. Due to geographical and other factors, the water quality in all parts of the country is uneven, and the water quality resources vary greatly. The use of water with high hardness over time will make people's skin dry, rough, and aging quickly. Therefore, people's demand for soft water continues to rise. Soft water contains no or less soluble calcium and magnesium compounds. Using soft water can effectively inhibit fungi and delay skin aging. , Prevent the scaling of heated water, which is not harmful to life. [0003] The existing water softeners and hot water devices on the market are independent products, and they need to ...

AI Technical Summary

Problems solved by technology

[0003] The existing water softeners and hot water devices on the market are independent products, which need to be installed independently during the installation process. Not only does it take up a lot of space, the purchase cost is high, and it is difficult to use and install. At present, there is no product that is both It can solve the problem of hot water demand and reduce the hardness of water

[0004] In addition, when the hot water device is applied in the "zero cold water" system (also known as the preheating circulation system), the circulating waterway where it is located is prone to impurities and scaling after long-term operation, requiring regular maintenance, which has a certain impact on the user experience
