Washing machine water inlet monitoring device and washing machine

Abstract

The invention discloses a washing machine water inlet monitoring device and a washing machine, and relates to the technical field of washing machines. The washing machine water inlet monitoring device of the present invention includes a control module, a monitoring module, a power supply module and an alarm module. When the washing machine is in a standby state, the alarm module is powered off, and the power supply module supplies power to the control module and the monitoring module; the monitoring module is used to monitor the washing machine The incoming water level signal is sent to the control module. The control module is used to receive the water level signal and judge whether the incoming water exceeds the safe water level. If so, control the alarm module to power on and make it send an alarm signal. The present invention also protects a washing machine with the above monitoring device. In the invention, the monitoring module and the control module are powered by the power supply module in the standby state, so that the washing machine can monitor whether the water inflow is abnormal in the standby state, and avoid abnormal water inflow problems such as overflow.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a washing machine water inlet monitoring device and a washing machine. Background technique [0002] At present, because the installation position of the washing machine is relatively partial, the water inlet pipe and the drain pipe will not be disconnected after being connected. When the washing machine is in the standby state, if the solenoid valve of the washing machine fails to close completely, since the water inlet pipe is always in a normal connection state, water will slowly flow into the machine from the gap that is not completely closed in the solenoid valve. Since the washing machine cannot monitor the condition of the whole machine in the standby state, if the user cannot detect the abnormal water intake of the washing machine in time, the water in the washing machine will increase until it overflows from other outlets of the washing machine. The appliance b...

AI Technical Summary

Problems solved by technology

Since the washing machine cannot monitor the condition of the whole machine in the standby state, if the user cannot detect the abnormal water intake of the washing machine in time, the water in the washing machine will increase until it overflows from other outlets of the washing machine. The appliance box overflows, and the water keeps flowing out, which may damage the floor and other furniture and facilities

[0003] At present, the washing machine is in standby state after running (standby state refers to the state after the washing machine is automatically shut down after running. At this time, the power cord of the washing machine is connected to the power plug, but the power switch is not turned on, and there is no display). All loads controlled by the strong current switch Power off; for loads controlled by non-strong current switches, part of the circuit is not powered off, but the water inflow monitoring of the washing machine cannot be realized

Therefore, the existing washing machine is in a standby state and does not have a monitoring function, and cannot monitor abnormal water inflow.
