Description
Technical field
The present invention relates to washing machine field, specifically vibration absorber, especially a kind of vibration absorber with function of weighing and have
The washing machine of the device.
Background technology
Existing automatic washing machine drives the washing tube for filling clothing to rotate and realize function of weighing using motor itself mostly.This claims
Weight implementation be：First, the first desired speed is reached by controlled motor, and motor is at the uniform velocity rotated with the first desired speed,
The first torque of now motor is measured, then controlled motor makes motor accelerate to the second desired speed from the first desired speed, measures
Motor from the first desired speed rise to the second desired speed when rising torque, finally controlled motor is even with the second desired speed again
Speed rotation, measures the second torque of now motor, and the changing value according to torque calculates the weight of washing tube undergarment；2nd, lead to
Cross controlled motor and reach the first desired speed, then allow motor to have a power failure suddenly, detection motor arrives the number of turns of static rotation after having a power failure,
Calculate the weight of washing tube undergarment；First desired speed can also be reached by controlled motor, then allow motor to have a power failure suddenly,
The counter electromotive force that detection motor is produced after having a power failure, calculates the weight of washing tube undergarment.
The measurement to clothes weight is either realized in above-mentioned which kind of mode, is all that clothes weight is measured by motor.These
Metering system often receives the influence of the conditions such as the species of motor, the tensile force of driving belt, the frictional force of washing tube system, its survey
Accuracy of measurement is not high, and the situation of false judgment is also very more.Clothing little in washing tube is often measured into many clothings,
Cause the waste of laundry water；Many times but many clothings in washing tube are measured into little clothing, cause water of doing washing
Deficiency, cause clothes washing unclean.This weighting manner can only be used as general reference, in addition can not be used as to water
How many judgements.Present people advocate environmental protection, not only the amount of saving water, and also to use detergent less, reach clothing, wash
Agent and the best match of water consumption are washed, the above-mentioned method weighed is difficult to meet user's requirement.
The Chinese patent of Application No. 201320340304.3 discloses a kind of washing machine with suspension, is related to washing machine to lead
Domain, contains casing and washing tube, it is characterised in that the washing machine also includes a suspension, and described suspension includes
Suspension pin, suspension rod, spring housing, spring, spring base, weighing sensor and sensor holder, the suspension is by hanging pin
It is fixedly connected with casing, is fixedly connected with washing tube by spring housing；Described suspension rod suspension is arranged on suspension pin；Described
Spring housing, spring, spring base, weighing sensor and sensor holder are all enclosed within suspension rod；Described spring suspension is installed on bullet
In the middle of spring set and spring base；Described weighing sensor is arranged between spring base and sensor holder, and sensor holder is relative with suspension rod
It is fixed.
Although said structure can accurate measurement, also there is following defect：Because weighing sensor is installed on suspension
On, washing machine component installs complex, and cabling is difficult, there is potential safety hazard；Further, since suspension is mainly used in subtracting
Bestir oneself use, the course of work, the vibrations of washing tube assembly are larger, cause to be installed on the weighing and sensing between spring base and sensor holder
Device pressure change is larger, reduction of service life.
In addition, the existing shock absorber damping and amortization certain because this body structure is present, often results in gravity non-linear with shock-absorbing spring
Relation, and whole machine, in the state of water inlet, often suspension rod spring can be pressed simultaneously, cause range not enough, influence weighing for washing machine.
The Chinese patent of Application No. 201210176786.3 discloses a kind of laundry of washing machine weight detection apparatus and application method,
Including the weighing device being arranged on washing machine and connect the weighing circuit of the weighing device, the weighing circuit include microprocessor,
It is serially connected and connects the piezo-resistance and partial pressure protective resistance of microprocessor, and resistance change by piezo-resistance is counted
Calculate.The weighing device is located at the top of outer casing upper cover plate, to facilitate the placement of clothing.The weighing device can be electronic balance etc.
Weighing device.
The structure is embedded in washing machine shell top equivalent to by existing electronic balance, although can measure the weight of clothing, but
It is first clothing must to be positioned on weighing device before washing measure every time, washing in washing machine is then put into again, user uses
Bother very much；Secondly, the device can not measure the water in washing machine.
Some manufacturer realizes function of weighing by installing foil gauge in washing machine foot, and is arranged on the periphery of bottom stud structure
Circuit is difficult connection, and cabling is difficult, and there is potential safety hazard, and because most of user custom places thing on casing of washing machine
Product are so as to cause measurement inaccurate, or need user to move article every time, in-convenience in use.
In view of this, it is special to propose the present invention.

The displacement △ δ 1=5.8-2.1=3.7mm (referring to Fig. 3) of support 55 and magnetic core 53, now, output frequency of weighing is 40.74KHz.
D：Peak load state, the decrement of weighing spring 51 is 171*9.8/4/59=7.2mm, magnetic core support 55 and magnetic core
53 displacement △ δ 2=7.2-2.1=5.1mm (referring to Fig. 4), now, output frequency of weighing is 42.1KHz.
Position additionally, due to magnetic core 53 causes to weigh the change of output frequency, and the position of magnetic core 53 depends on weighing spring 51
Displacement.And passing through stress balance can draw, the power of weighing spring 51 is equal to shock-absorbing spring 31 and other suspension rods damp
With joint efforts, therefore, changed come output frequency by weighing spring 51 and evaded the influence that other suspension rods are damped, it is more accurate to make to weigh.
Embodiment in above-described embodiment can be further combined or replace, and embodiment is only to preferred reality of the invention
Apply example to be described, not the spirit and scope of the present invention are defined, on the premise of design philosophy of the present invention is not departed from,
The various changes and modifications that professional and technical personnel in the art make to technical scheme, belong to protection model of the invention
Enclose.
