Technical Problem

[0002]现有燃气热水器使用水泵均只具有单一进冷水功能，无混水功能，热水器再次开启出现冷水过多，出水温度波动大，影响用户体验，且现有燃气热水器零冷水产品若想进行混水需使用：水泵外加其他结构件共同作用混水后流入水泵内部，外加零部件连接增加连接漏水风险及提升零件成本

Benefits of technology

[0016] This application embodiment achieves three functions in one unit through the injection molding of the water circuit regulating valve core: mixing, increasing water volume, and decreasing water volume. This reduces manufacturing difficulty, improves the overall reliability of the parts, and enhances the water regulation capability of existing integrated water pumps. The improved water pump can achieve flow rate increase, flow rate decrease, water pressure increase, and mixing, meeting the user's needs for constant temperature performance in winter or when the inlet water temperature is low. It can adjust the water flow rate upon restarting, reducing the flow through the water heater, reducing outlet water temperature fluctuations, and improving the user experience. At the same time, it can achieve dual circulation of the whole machine during restarting and stopping, eliminating the need for additional parts to mix water before it enters the water pump, reducing the risk of connection leakage, and improving product reliability and installation convenience.

Abstract

The application relates to a direct-current variable-frequency water pump with a water mixing function, which comprises a cold water inlet channel, a mixed water inlet channel, a water flow size adjusting device and a water outlet channel. The cold water inlet channel comprises a shell, a water flow sensor and a rotor. The mixed water inlet channel comprises a water channel stop valve one, a mixed water inlet channel opening, a one-way valve and a mixed water channel inlet. The water channel adjusting valve core is integrally injection molded, three functions of mixed water, water flow increase and water flow decrease are integrated, the production and manufacturing difficulty is reduced, the overall reliability of the part is improved, the existing integrated water pump water adjusting capacity is improved, the water flow of the subsequent water pump can be increased, the water flow can be reduced, the water pressure can be increased and the mixed water can be realized, the constant temperature performance of the user in winter or the low water temperature can be met, the water flow can be adjusted when being turned on again, the water flow through the water heater is reduced, the water outlet temperature fluctuation is reduced, and the user experience is improved.
