Problems solved by technology

[0003] However, the working power of electric water heaters is relatively large, and usually one electric heating rod can reach thousands of watts, so if multiple electric heating rods work at the same time, it is easy to exceed the maximum electricity load allowed by the user's family. Once this happens , it will cause tripping and power failure, which will bring a lot of inconvenience to users
In addition, due to the inconsistency in the power supply design standards of residential buildings in different periods or regions, the corresponding rated power loads are also different.
However, there is no water heater that can take into account different rated power loads in the market so as to maximize the working efficiency of multiple electric heating rods

Embodiment Construction

[0030] figure 1 Shown is a specific embodiment of the water heater of the present invention. In this implementation, the water storage type electric water heater is taken as an example. Of course, the present invention can also be applied to other types of water heaters, such as gas water heaters, instant water heaters, and the like. The water heater 100 includes an inner tank 10 for storing heated water. Usually, an outer shell (not shown) is covered outside the inner tank, and a heat insulation layer (not shown) formed between the inner tank and the outer shell and filled with foam material (such as made of polyurethane material). The liner 10 is roughly in the shape of a barrel extending along the longitudinal axis, and is equally divided into an upper half and a lower half in the radial direction. It has a barrel-shaped wall, usually made of ferrous metal, such as steel, iron Wait. The bottom of the inner tank 10 is provided with a water inlet 81 for introducing cold wa...

Abstract

The invention discloses an electric water heater, which comprises a heat source, a water inlet, a water outlet, an input device and a controller, wherein the water inlet and the water outlet are respectively used for inflowing of cold water and outflowing of hot water heated by the heat source; the input device is at least used for setting a higher limit of working power of the heat source; and the controller is connected with the heat source and the input device, and is used for receiving a setting signal representing the higher limit of the working power from the input device, responding to the setting signal, and controlling the heat source to work under the condition of the higher limit or below the higher limit of the working power. Through the arrangement, a user is allowed to set the maximum working power of the water heater according to the rated electrical load of own family, so that the electrical safety of the family of the user is ensured, and the working efficiency of the water heater is maximized.

Description

technical field [0001] The invention relates to an electric water heater, in particular to a storage type electric water heater. Background technique [0002] Due to its mature technology and high safety performance, storage-type electric water heaters are currently widely used by Chinese families. Such an electric water heater usually includes an inner tank for storing water, an electric heating rod arranged in the inner tank for heating water, an insulating layer and a shell wrapped outside the inner tank. Early electric water heaters had only one heating rod. However, when a small amount of hot water needs to be used, the electric heating rod will heat the water in the entire inner tank to the set temperature, which not only needs to wait for a long time, but also because a large amount of hot water in the tank will not be used, Thereby causing unnecessary waste of energy. In order to solve this problem, current electric water heaters have begun to use two or more heat...
