Abstract
The utility model discloses a magneto-resistive type eccentric load sensor in a full-automatic pulsator washing machine. The magneto-resistive type eccentric load sensor is characterized in that a reed pipe is fixedly arranged on a washing machine box body, wherein a permanent magnet is fixedly arranged on the outer barrel wall of a wash bucket; and a switching signal of the reed pipe is used as a detection output signal. According to the magneto-resistive type eccentric load sensor in the full-automatic pulsator washing machine disclosed by the utility model, the detection for the eccentric-load vibration of the wash bucket is carried out by adopting the reed pipe; the process is free of collision and noises; the service life is long; the condition is stable; and the field debugging is not needed.
Description
Technical field
The utility model relates to a kind of for full-automatic impeller type washing machine reluctance type unbalance loading sensor.
Background technology
In the prior art, for detection of wash bucket unbalance loading after vibration position two schemes is arranged in the full-automatic pulsator washing machine: the one, adopt linked switch, be door for washing machine to be uncapped detect the mechanical contact-type switch of combining with wash bucket unbalance loading after vibration position probing, rely on the stroke that changes the contact to come on-off circuit; Another kind is to adopt the independent switch formula namely to detect separately the mechanical contact-type switch of wash bucket unbalance loading after vibration position, is to rely on the stroke that changes the contact to come on-off circuit equally.
Above-mentioned dual mode all is to adopt mechanical contact switch, by forcing to make switch contact separate to detect the unbalance loading position of washing machine tub behind the washing machine tub mechanical collision.But the easy oxidation of mechanical contact, easy to wear; Have collision noise, switch yielding, affect switch service life.Simultaneously in first kind of way, because the unbalance loading of wash bucket detects with the control test set of uncapping and is combined, when producing, washing machine need the on-the-spot contact position of adjusting to guarantee the door closure distance of uncapping, the uncap error of Height Adjustment of door closure can have influence on the precision of washing machine tub unbalance loading after vibration position, there is related impact, bad to the unbalance loading detection uniformity of washing machine.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, and reluctance type unbalance loading sensor in a kind of collisionless noise, long service life, in stable condition, the full-automatic impeller type washing machine that do not need field adjustable is provided.
The utility model is that the technical solution problem adopts following technical scheme:
The design feature of reluctance type unbalance loading sensor is in the utility model full-automatic impeller type washing machine: be fixedly installed tongue tube at casing of washing machine, be fixedly installed permanent magnet at the wash bucket outer barrel wall, with the switching signal of described tongue tube output as detecting output signal.
Compared with the prior art, the utility model beneficial effect is embodied in: the utility model adopts the tongue tube device to carry out the detection of wash bucket unbalance loading vibration, process collisionless noise, long service life, in stable condition, do not need field adjustable.
Description of drawings
Fig. 1 is the utility model structural representation;
Number in the figure: 1 support; 2 tongue tubes; 3 wash bucket outer barrel walls; 4 permanent magnets.
The specific embodiment
Referring to Fig. 1, the present embodiment is to be fixedly installed tongue tube 2 by support 1 on casing of washing machine, is fixedly installed permanent magnet 4 at wash bucket outer barrel wall 3, with the switching signal of tongue tube output as detecting output signal.
The present embodiment is the position of identifying washing machine tub unbalance loading after vibration with tongue tube 2 and the cooperating of permanent magnet 4.And then the working condition of control washing machine.
During the clothing unbalance loading, the wash bucket vibration amplitude of oscillation is excessive when causing laundry machine dehydration in washing machine tub, wash and the machine outer barrel wall on the permanent magnet as trigger source excite tongue tube to make control circuit closed, reach the purpose that detects the wash bucket unbalance loading.
Consider the difference of polarization direction, in the implementation, can on the wash bucket outer barrel wall, arrange two sensors by the orientation that is 90 °.
Claims (1)
1. reluctance type unbalance loading sensor in the full-automatic impeller type washing machine, it is characterized in that: be fixedly installed tongue tube (2) at casing of washing machine, be fixedly installed permanent magnet (4) at wash bucket outer barrel wall (3), with the switching signal of described tongue tube (2) output as detecting output signal.
