Embodiment 1

[0032] Embodiment 1 of the present invention provides an electric water heater, such as figure 1 As shown, it includes a housing 1, an inner tank 2, a heater 3, a temperature acquisition unit 4 and a controller 5, the inner tank 2 is located in the housing 1 for water storage, and the heater 3 is located in the inner tank 2 and its end extends out of the inner tank 2 and is connected to the controller 5 arranged in the housing 1, and the temperature acquisition unit 4 is arranged on the corresponding plug of the electric water heater and connected to the controller 5;

[0033] Specifically, the plug 8 includes a neutral pin 81, a live pin 82 and a ground pin 83, and the temperature acquisition unit 4 is adjacent to the neutral pin 81 or the live pin 82;

[0034] In this way, with the above-mentioned structure, the water in the inner tank 2 is heated by the heater 3, and during the heating process: the temperature acquisition unit 4 collects the real-time temperature on the plu...

Embodiment 2

[0051] Embodiment 2 of the present invention provides a control method for an electric water heater, such as Figure 5 As shown, it is used to control the electric water heater described in Embodiment 1, specifically implemented according to the following steps:

[0052] S1, the temperature collection unit 4 collects the real-time temperature on the plug corresponding to the electric water heater, and transmits the real-time temperature to the controller 5;

[0053] S2, the controller 5 controls the working state of the heater 3 according to the relationship between the real-time temperature and the preset temperature threshold, specifically:

[0054] When the real-time temperature is greater than the temperature threshold, the heater 3 stops working; otherwise, the heater 3 continues to work.

[0055] In this embodiment, the real-time temperature on the plug corresponding to the electric water heater is collected by the temperature collection unit, and the real-time temperat...

Abstract

The invention discloses an electric water heater and a control method thereof. The electric water heater comprises a housing, a liner, a heater, a temperature acquisition unit and a controller. The liner is located in the housing for storing water, the heater is located in the liner and the end part of the heater extends out of the liner and is connected to the controller arranged in the housing,and the temperature acquisition unit is arranged on a plug corresponding to the electric water heater and is connected to the controller. The temperature acquisition unit acquires a real-time temperature of the plug corresponding to the electric water heater and transfers the real-time temperature to the controller. When the real-time temperature is greater than a temperature threshold value, theheater stops working. On the contrary, the heater works continuously. By setting the temperature threshold value, when the real-time temperature is greater than the temperature threshold value, the heater is cut off immediately, so that the heater stops working. In this way, parts in the electric water heater are prevented from being burnt, and safety problems due to overtemperature of the plug are further prevented.

Description

technical field [0001] The invention belongs to the technical field of electric water heaters, and in particular relates to an electric water heater and a control method thereof. Background technique [0002] High-power electrical products have been widely used in family life. These electrical appliances basically use ordinary three-pole plugs or leakage protection plugs. Electric water heater products belong to the category of high-power products. The use of ordinary triangular plugs is more widely used. [0003] However, due to some uncertain factors, such as the use of inferior sockets, the use of sockets that do not match the plug, the aging of the socket, etc., the contact resistance between the plug and the socket increases, and prolonged heating will cause a fire, and there is a serious safety hazard. Hidden danger. Contents of the invention [0004] In order to solve the above problems, the present invention provides an electric water heater. When the temperature...
