Embodiment 1

[0049]In order to solve the technical problem that the current water heater does not support the user to directly set the bath time, this embodiment proposes a control method for the electric water heater, which can support the user to directly set the bath time, and the user can control the setting through the remote control or through the electric water heater. Control panel setting, this embodiment mainly explains in detail how the electric water heater performs corresponding heating control and calculation of the remaining bathing time according to the set bathing time. It should be noted that the electric water heater in this embodiment defaults to be able to perform static Heating and dynamic heating electric water heaters, that is, electric water heaters with both electric heating tubes and dynamic heating tubes. The water storage container of the electric water heater is a water tank, and heating components such as electric heating tubes and dynamic heating tubes are arr...

Embodiment 2

[0088] This embodiment proposes an electric water heater, based on the control method described in Embodiment 1, such as figure 2 shown, including:

[0089] 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;

[0090] 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;

[0091] 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;

[0092] 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 an electric water heater control method and an electric water heater. The method comprises the following steps that (1), bath time set by a user is collected, and an electric heating tube is switched on; (2), current temperatures in a water tank is periodically detected in the heating process of the electric heating tube; (3), it is detected whether or not a dynamic heatingtube is switched on, and a hot water recharge rate of the dynamic heating tube is calculated; (4), remaining bath time t is calculated and displayed; (5), when the remaining bath time t is increasedto the bath time, the heating of the electric heating tube is stopped, and a current temperature in the water tank is detected to be Rmax; (6), the remaining bath time t is periodically calculated continuously, and the display is updated. The electric water heater control method has the advantages that the user can freely customize the bath duration, a system collects the bath time set by the user, switches on the electric heating tube to heat the water to a temperature capable of meeting the requirement of the user bath duration, also can calculate and display the remaining bath duration periodically in the whole bate process of the user, so that the remaining bath time is more visual.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to an electric water heater control method 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, but cannot display the bathing time that the water stored at the current temperature can satisfy. The bathing time that can be satisfied by the amount of water drops sh...
