Vibration alarming system for full-automatic washing machine

Abstract

The invention relates to a vibration alarming system for a full-automatic washing machine. The vibration alarming system comprises a safety rod assembly and a micro switch assembly positioned on one side of the safety rod assembly, wherein the safety rod assembly comprises a safety rod, a safety rod base, a first seal ring and a second seal ring. The first seal ring and the second seal ring are positioned in the middle of the safety rod base, and a reset spring is fixedly arranged between the first seal ring and the second seal ring. A roller is arranged at one end of the safety rod, the other end of the safety rod sequentially penetrates through the centers of the first seal ring and the second seal ring, and the two ends of the safety rod are connected with the inner wall of the safety rod base respectively through the first seal ring and the second seal ring. One end with the roller, of the safety rod is close to a case body, and the other end of the safety rod is close to the micro switch assembly. By means of the vibration alarming system, the situation that vibration exceeds a limit value in the dehydration process of the washing machine can be effectively prevented, and smooth dehydration operation of the washing machine can be ensured.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a vibration alarm system for a fully automatic washing machine. [0002] Background technique [0003] In order to solve the problems such as serious vibration of the washing machine caused by the eccentricity of the clothes and loud vibration noise during the dehydration process of the washing machine, the casing of the washing machine is damaged or the movement of the washing machine affects the normal use, etc., the existing fully automatic washing machines are equipped with a bucket switch. Currently, if figure 2 As shown, the barrel switch position 16 of the existing fully automatic washing machine is fixed, waiting passively for the impact of the outer barrel cover hitting the safety switch position 17. However, the vibration trajectory of the outer tub of the washing machine during the dehydration process is usually irregular, thus causing the inaccurate problem...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems such as severe vibration of the washing machine caused by the eccentricity of the clothes and loud vibration noise during the dehydration process of the washing machine, the damage to the washing machine box or the movement of the washing machine affects the normal use of the washing machine, etc., the existing fully automatic washing machines are equipped with a bucket switch

Currently, if figure 2 As shown, the barrel switch position 16 of the existing fully automatic washing machine is fixed, passively waiting for the impact of the outer barrel cover to hit the safety switch position 17

However, the vibration trajectory of the outer drum of the washing machine during the dehydration process is usually irregular, so the problem of inaccurate alarm of the drum switch is caused.

For example, sometimes the washing machine vibrates but the outer tub does not hit the cabinet, but touches the tub switch, resulting in oversensitivity; Do not reach the bucket switch, which will cause damage to the washing machine cabinet or overturn and cause danger
