Abstract

The invention discloses an electric water heater and a control method, and belongs to the technical field of water heaters. The electric water heater comprises an inner container, an electric heatingpart and an electric heat preservation part, the electric heating part is arranged in the inner container and can heat water in the inner container to a set temperature, the electric heat preservationpart is arranged outside the inner container in a surrounding mode and can carry out heat preservation on the water in the inner container, and the electric heat preservation part and the electric heating part work alternately. The control method for the electric water heater comprises the steps that when the electric heating part is in an on state, the electric heat preservation part is turned off; and the actual temperature of the water in the inner container is acquired, when the actual temperature is equal to the set temperature, the electric heating part is turned off, and meanwhile theelectric heat preservation part is turned on. According to the electric water heater and the control method, heat preservation is carried out the water in the inner container through the electric heatpreservation part, heat loss of the water is slowed down, the phenomenon that the electric heating part is frequently turned on and turned off can be avoided, and therefore the service life of the electric heating part is prolonged, incrustation is reduced, a foaming agent does not need to be arranged, and a good heat preservation effect is achieved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an electric water heater and a control method. Background technique [0002] The existing electric water heater includes an inner bag and a shell, the inner bag is arranged in the outer shell, and the inner bag is used for holding water. A water inlet pipe, a water outlet pipe and an electric heating pipe are arranged in the inner container, and the electric heating pipe is used for heating the water in the inner container. [0003] Under normal circumstances, when the electric heating tube heats the water in the inner tank to the set temperature, the heating is stopped. Because there is a temperature difference between the water in the inner tank and the surrounding medium, the heat of the water will continue to exchange heat with the surrounding medium, resulting in a decrease in the water temperature, which cannot provide constant temperature water to the user. [0004...
