Abstract

The invention discloses a preheating and instant heating dual-mode water heater and belongs to the field of water heaters. The preheating and instant heating dual-mode water heater comprises a storage type hot water device, an instant heating type hot water device, a pipe valve assembly and a pressure regulating cylinder, wherein the pressure regulating cylinder is used for storing pressure and reducing the overall pressure borne by the whole preheating and instant heating dual-mode water heater. The storage type hot water device is connected with the instant heating type hot water device through the pipe valve assembly. The storage type hot water device comprises a liner communicating with the pipe valve assembly. The pressure regulating cylinder directly communicates with the liner or communicates with the liner through a water inlet / outlet pipe, or the pressure regulating cylinder directly communicates with the pipe valve assembly or communicates with the pipe valve assembly through the water inlet / outlet pipe. According to the preheating and instant heating dual-mode water heater provided by the invention, the water storage liner is in the low-pressure state for a long time, hot water backflow is avoided, and the problems that a dual-mode electric water heater is prone to scaling and short in service life can be effectively solved.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a pre-dual-mode water heater. Background technique [0002] The pre-heating dual-mode water heater is a kind of fast electric water heater, which has two heating modes: instant heating and preheating. [0003] The pre-instant dual-mode water heater not only overcomes the shortcomings of storage-type electric water heaters such as large volume, slow heating, and high energy consumption, but also overcomes the installation bottleneck of high-power installation of instant electric water heaters, and has good market promotion value. But the fatal problem of the pre-instant dual-mode water heater is that it makes the tank of the water storage type water heater communicate with the shell where the heating body of the instant water heater is located, and the instant water heater sometimes needs to withstand hot water from the inner tank If the heating element is soaked in warm water for a ...
