Washing machine and washing machine control method for automatically judging the position of drain pipe

Abstract

The invention relates to a washing machine capable of automatically judging the position of a drain pipe and a washing machine control method. The washing machine comprises the full-automatic procedures of washing, rinsing and drying, wherein the washing procedure comprises the processes of water supply, washing and drainage. The washing machine is provided with a magnet and a switch element for judging the position of the drain pipe; and the circuit of the switch element is connected with a computer programmable logic controller. When the washing is finished and the drainage process is started, the control method comprises the following steps of: judging whether the switch element is switched off or not, and transmitting a switch signal to the computer programmable logic controller; if the switch element is switched off, transmitting an alarming signal to indicate the laying-down of the drain pipe by using the computer programmable logic controller; and if the switch element is cut off, transmitting an electrifying signal to a drainage control element and starting draining the washing machine by using the computer programmable logic controller. In the technology of the invention, washing time can be effectively utilized and the safety reliability of the product is improved.

Description

technical field [0001] The invention relates to a fully automatic washing machine, in particular to a washing machine for automatically judging the position of a drain pipe and a control method for the washing machine. Background technique [0002] A fully automatic washing machine generally performs washing, rinsing, and dehydration procedures according to a set program. The washing program / rinsing program includes a water intake process, a washing / rinsing process, and a draining process. During use, if the user forgets to put the drain pipe into the downpipe, there is currently no method to provide the user with an effective prompt or solution. [0003] Although some lower drainage washing machines on the market have an alarm function that sets the drainage time too long, that is, if the drainage water level does not reach the predetermined value within the set time, the washing machine will give a buzzer alarm. However, the alarm time of this method is generally set to 8...

Problems solved by technology

However, the alarm time of this method is generally set to 8-15 minutes, which is a long time, and this alarm is not the only alarm that does not put the drain pipe into the downpipe. If the drain valve is blocked, the drainage will be slow or the drainage time will be too long However, the alarm cannot clearly indicate the cause of the washing machine failure.

When the washing machine is a washing machine that drains from the bottom, if the drain pipe is not put into the drain pipe, it often causes the user to think that when the clothes are about to be washed, they find that the washing water has not been drained, and the clothes have not been rinsed and dehydrated, resulting in a waste of time; For the washing machine, if the drain pipe is not put into the downpipe, it will cause more serious consequences. For example, the drain pump will discharge the dirty water from the washing machine to the outside of the washing machine, and the water will flow everywhere in the room, and even splash on the socket and other electrical facilities, bringing safety hazards
