Air conditioner with electric shock prevention function

Abstract

The invention discloses an air conditioner with an electric shock prevention function. A detection module is used for detecting the opening or closing state of an outer casing of the air conditioner, and sending a pulse signal to a main control module. When a user opens the outer casing of the air conditioner, the main control module can control a switch module to disconnect the output end of a power source module according to the pulse signal of the detection module, and start a prompting module to prompt the user to cut off a power source of the air conditioner. After the user opens the outer casing, as the switch module can disconnect the output end of the power source, the air conditioner stops working, and the prompting module prompts the user to cut off the power source. Therefore, the danger of electric shock of an operator is prevented in advance, the operator can cut off the power source according to the prompting of the prompting module, and the electric shock danger is avoided for the operator.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner with an electric shock prevention function. Background technique [0002] At present, electric leakage protection switches are installed in household electricity. In case of electric shock, the power supply will be automatically cut off to play a protective role. However, this protection is a hysteresis protection, and the power supply can only be cut off in the event of an electric shock. [0003] In the use of the air conditioner, if there is an electric shock, the power supply can only be cut off through the leakage protection switch to play a protective role. Whether it is a wall-mounted air conditioner or a cabinet-type air conditioner, it is necessary to work at high altitude when cleaning the filter screen or performing inspection and maintenance on the internal and external units of the air conditioner. And there are many high-rise buildings in cities n...

Problems solved by technology

Moreover, there are many high-rise buildings in cities now, and the external units of air conditioners are generally installed outdoors. When testing and maintaining the external units of air conditioners, if the maintenance personnel get an electric shock during work, it will be life-threatening.

At present, only relying on the post-event protection of the leakage protection switch cannot guarantee the personal safety of the operator.

At present, most of the air conditioner's external units are hung outdoors. After a long time, the outer shell of the external unit is easily damaged, resulting in damage to internal components, making the air conditioner unable to work normally, and affecting the work and life of users.
