Abstract

The invention belongs to the technical field of gas water heaters and discloses an electrically auxiliary preheating circulation gas water heater, a preheating circulation system and a control method.According to the electrically auxiliary preheating circulation gas water heater, a water outlet pipeline is provided with an intelligent heating module connected to a controller, after a preheating circulation function of the gas water heater is started, if the temperature of water heated by the minimum heat load of the gas water heater is higher than the set water outlet temperature Ts, the controller stops gas heating and controls the intelligent heating module to start, and the water is heated to the set water outlet temperature Ts. Through the gas water heater, when the water is heated with gas by the minimum heat load, if the temperature of the heated water is still higher than the set water outlet temperature, gas heating can be stopped, heating is conducted through the intelligentheating module till water is heated to the needed set water outlet temperature, and the requirements that on the premise that zero cold water is achieved, the problem of uneven water outlet temperatures is avoided, a user does not need to draw off water to wait for hot water, and hot water is available at any time are met.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to an electric-assisted preheating cycle gas water heater, a preheating cycle system and a control method. Background technique [0002] Now domestic gas water heaters are becoming the first choice of water heaters because of their characteristics of instant hot water. However, the gas water heater has the following problems when it is used: when the gas water heater is turned on, it is necessary to discharge the cold water retained in the hot water outlet pipeline before the hot water can be released, causing the user to wait and the released cold water is wasted; when the gas water heater is turned on again When the water outlet valve is turned off, there will be hot and cold water, which will affect the comfort of the user. [0003] In order to solve the above problems, a water heater with a preheating cycle function is currently designed, which returns the cold water ...
