Circuit structure of water dispenser

Abstract

The invention discloses a circuit structure of a water dispenser, comprising a direct-current power supply module, a relay module, a control module, a sensor module and a leakage protection module. The direct-current power supply module is electrically connected with each circuit module. The sensor module is connected with the input end of the control module, the output end of the control module is connected with the relay module, and the electric leakage protection module is connected with the relay module. The electric leakage protection module is configured to cut off the control of the control module on the relay module and disconnect the relay module when electric leakage occurs. According to the invention, the leakage protection module is arranged to detect whether there is electricleakage in the water dispenser in the power-on process, and if electric leakage occurs in the water dispenser, the electric leakage protection module cuts off the control of the control module on therelay module and enables the relay module to be disconnected, so that an electric leakage protection function is achieved, the direct-current power supply module supplies power normally, and work of other weak current modules in the water dispenser is not affected.

Description

technical field [0001] The invention relates to the technical field of water dispensers, and more specifically relates to a circuit structure in a water dispenser. Background technique [0002] Water dispenser is a common electrical equipment, mainly used to improve drinking water service for the general public. Conventional water dispensers are mainly equipped with temperature detection function and heating function. When the temperature of the water stored in the water dispenser is lower than the set value, the heating device in the water dispenser is controlled to be connected to the mains, and the water stored in the water dispenser is Water is heated. [0003] Since the water dispenser is a high-voltage power supply device and has a high probability of leakage, most water dispensers are equipped with leakage protection devices. When a leakage occurs, the leakage protection device cuts off all circuit modules in the water dispenser and the market Electricity connection...

Problems solved by technology

[0003] Since the water dispenser is a high-voltage power supply device and has a high probability of leakage, most water dispensers are equipped with leakage protection devices. When a leakage occurs, the leakage protection device cuts off all circuit modules in the water dispenser and the market Electricity connection, although the leakage protection function can be realized in the prior art, the water dispenser is disconnected from the mains, causing other weak current modules (such as communication modules, alarm modules, etc.) in the water dispenser to realize auxiliary functions , display module, etc.) will fail together, which will also cause inconvenience to users
