Electric water heater and control device thereof

Abstract

The invention discloses an electric water heater and a control device thereof. A water flow generation device is arranged and comprises a water inlet, a water inlet stop port, a water outlet stop port, a rotor and coils, wherein the water inlet stop port, the water outlet stop port and the rotor can form a movable rotor after being combined; the movable rotor is arranged in the water inlet; the coils are arranged on the periphery of the movable rotor; flow deflectors of the water inlet stop port of the movable rotor are inclined sheets, and blades of the rotor and flow deflectors of the water outlet stop port are vertical sheets. According to the electric water heater and the control device thereof, the water flow generation device is adopted for automatically controlling work of electric heaters, the optical radiation electric heaters are adopted for heating, and the control mode is simple; the electric heaters can be taken out from cavities of heat conduction blocks for being replaced conveniently and make contact with the heat conduction blocks in a non-conductive mode, so that use is safer; array diodes are adopted for carrying out gear display control over a digital displayer of the electric water heater. The electric water heater and the control device thereof have the advantages of being low in production cost and maintenance cost.

Description

technical field [0001] The invention relates to the technical field of electric heaters, in particular to an electric water heater and a control device thereof. Background technique [0002] The magnetic floating water flow switch of the existing electric water heater is used in areas with poor water quality, and it is easy to get stuck, resulting in dry burning of the electric water heater. [0003] At present, the application of electric heaters is very common. It is used in electric water heaters and metal heaters in heaters and other equipment, such as figure 1 , figure 2 As shown, the electric heating part of the metal heater is integrated with the heating part. After the damage, due to the high repair cost, it is generally not repaired, and the new metal heater is directly replaced, which is a great waste of resources. The metal heater used in the instant water heater is limited by volume and space, the length of the heating tube in the metal heater is limited, and ...

[0002] The magnetic floating water flow switch of the existing electric water heater is used in areas with poor water quality, and it is easy to get stuck, resulting in dry burning of the electric water heater

[0003] At present, the application of electric heaters is very common. It is used in electric water heaters and metal heaters in heaters and other equipment, such as figure 1 , figure 2 As shown, the electric heating part of the metal heater is integrated with the heating part. After the damage, due to the high repair cost, it is generally not repaired, and the new metal heater is directly replaced, which is a great waste of resources.

The metal heater used in the instant water heater is limited by volume and space, the length of the heating tube in the metal heater is limited, and the heat load on the wall of the heating tube is very large, which is very easy to generate scale. The heat energy emitted by the metal heater cannot be well dissipated from the wall of the heating tube of the heater to the heated water, which will cause the temperature in the heating tube of the metal heater to be too high and cause damage

And the heating pipe wall of the metal heater is in direct contact with the heated water flow. When the metal heater leaks electricity, it will cause the heated water flow to be charged, and the metal parts in the electric water heater that are in contact with the water flow will be charged. security risks
