Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The invention provides an electric water heater, figure 1 For an embodiment of the electric water heater provided by the present invention, please refer to figure 1 , the electric water heater 100 includes a shell 1 and a water tank 2, the water tank 2 is used to store water, and the water in the water tank 2 is distributed in layers, which is specifically shown as: the water located at the upper position in the water tank 2 The temperature is higher than that of the water located at the lower position in the water tank 2, that is, it is hot on the top and cold on the bottom. The water tank 2 is equipped with a water inlet pipe 21 and a water outlet pipe 22, ...

Abstract

The invention discloses an electric water heater and a heating control method. The electric water heater comprises a water tank, a heating device, a first temperature sensor, a second temperature sensor and a controller; the second temperature sensor and the first temperature sensor are correspondingly arranged on two positions, located in an up and down spaced mode, of the water tank, the heating device comprises a first heater, and the controller controls the first heater to work according to the descent speed of the temperature detected by the first temperature sensor. When a user uses water, water is injected into the water tank through a water inlet pipe, and the first temperature sensor located on the lower portion detects the descent of the temperature firstly, so that the controller can control the first heater to be started in time to conduct heating on the water in the water tank, and the situation that due to the fact that the temperature of the water on the lower portion of the water tank is too low and the temperature of the subsequently supplied hot water of the electric water heater is not stable, the use comfort degree of the user is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electric water heater and a heating method thereof. Background technique [0002] At present, storage-type electric water heaters are mostly heated by electric water heaters, and the required water temperature is set before use. When the water temperature reaches the preset water temperature, the temperature control device of the electric water heater (the temperature control device is arranged A specific position, such as being arranged in the middle of the inner tank) controls to disconnect the power supply of the electric water heater and stop heating. When the water temperature drops to a certain temperature, the temperature control device of the electric water heater restarts the electric water heater for heating, and the cycle repeats. Due to the natural convection characteristics of water, the water in the inner tank is layered (hot water in the upper part ...
