Embodiment 1

[0049]In order to solve the technical problem that current water heaters cannot accurately display the remaining bathing time, this embodiment proposes a control method for an electric water heater with dynamic heating function. The calculation of bathing time will be described in detail. It should be noted that the electric water heater in this embodiment defaults to an electric water heater that can perform static heating and dynamic heating at the same time, that is, it has both electric heating tubes and dynamic heating tubes. The water storage of the electric water heater The container is a water tank, and the heating components such as electric heating tubes and dynamic heating tubes are set in the water tank. The water tank of the electric water heater is closed, that is, the water in the water tank is always full, and when the hot water is released, it will enter the cold water to supplement at the same time, and release The amount of water is equal to the amount of wat...

Embodiment 2

[0087] This embodiment proposes an electric water heater, based on the control method described in Embodiment 1, such as figure 2 shown, including:

[0088] The water tank 11 is connected with the water inlet pipe 12 for entering the cold water and the water outlet pipe 13 for the hot water respectively;

[0089] The electric heating device comprises an electric heating tube 141 and a dynamic heating tube 142, the electric heating tube 141 is used for overall heating of the water in the water tank 11; the dynamic heating tube 142 is used for locally heating the water in the water tank 11;

[0090] At least one water tank temperature sensor 15 is arranged in the water tank 11 for detecting the current temperature of the water in the water tank 11;

[0091] The control device 16 is connected with the electric heating device and the water tank temperature sensor 15 respectively, and is used to receive the temperature data collected by the water tank temperature sensor 15, colle...

Abstract

The invention discloses a control method of an electric water heater with a dynamic heating function and the electric water heater. The control method includes the following steps of (1) collecting user-defined temperature R, and switching on an electric heating pipe; (2) during heating of the electric heating pipe, periodically detecting the current actual temperature Rt of the interior of a water tank; (3) detecting whether or not the dynamic heating pipe is switched on, and calculating a hot water supplementation rate of the dynamic heating pipe if yes; (4) calculating remaining bath time tand displaying the remaining bath time t; (5) when water in the water tank is heated to the set temperature R, stopping heating of the electric heating pipe; (6) periodically continuing calculation of the remaining bath time t and updating the display. By means of the control method of the electric water heater with the dynamic heating function, the remaining bath time can be displayed for users,the users can have visual understanding on the amount of hot water in the water tank, and the problems of electricity waste or bathing comfort decline due to excessive heating or insufficient heatingcan be avoided.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to a control method for an electric water heater with a dynamic heating function and the electric water heater. Background technique [0002] Most of the water heaters currently on the market, the user sets the heating temperature, but does not know the corresponding bathing time, and the user has no idea how many degrees should be set to satisfy the bathing time. Most of them are set to the highest temperature, and only part of the water is used in the bath, and the remaining hot water is basically wasted. Moreover, it takes a long time to heat up to the highest temperature, and the user needs to wait for a long time. [0003] At present, the water heaters on the market can only see the temperature of the water stored in the water tank, and the displayed temperature cannot represent the real temperature in the water tank. Often, the displayed temperature will drop s...
