Description
Technical Field
The invention relates to the field of washing machines, in particular to a vibration damper, and particularly relates to a vibration damper with a weighing function and a washing machine with the same.
Background
Most of the existing full-automatic washing machines utilize a motor to drive a washing barrel filled with clothes to rotate so as to realize a weighing function. The weighing is realized in the following way: firstly, a first torque of a motor is measured by controlling the motor to reach a first preset rotating speed and enabling the motor to rotate at a constant speed at the first preset rotating speed, then the motor is controlled to accelerate the motor from the first preset rotating speed to a second preset rotating speed, a rising torque of the motor when the motor rises from the first preset rotating speed to the second preset rotating speed is measured, finally the motor is controlled to rotate at a constant speed at the second preset rotating speed, a second torque of the motor at the moment is measured, and the weight of clothes in a washing barrel is calculated according to a change value of the torque; secondly, controlling the motor to reach a first preset rotating speed, then enabling the motor to suddenly power off, detecting the number of turns of the motor which is in a static rotating state after power off, and calculating the weight of clothes in the washing barrel; the weight of the clothes in the washing barrel can be calculated by controlling the motor to reach a first preset rotating speed, then enabling the motor to be powered off suddenly, detecting the counter electromotive force generated after the motor is powered off and calculating the weight of the clothes in the washing barrel.
No matter which way the measurement of the weight of the laundry is carried out, the weight of the laundry is measured by the motor. These measurement methods are often influenced by conditions such as the type of the motor, the tension of the transmission belt, the friction force of the washing tub system, and the like, the measurement precision is not high, and the conditions of wrong judgment are very many. A few clothes in the washing barrel are often measured into a great number of clothes, so that the waste of the washing water quantity is caused; many times, a lot of clothes in the washing barrel are measured into few clothes, so that the quantity of the washing water is insufficient, and the clothes are not cleaned cleanly. This weighing method can only be used as a general reference, and in addition, cannot be used as a judgment for the amount of water. At present, people advocate environmental protection, not only the water consumption needs to be saved, but also the detergent needs to be used less, the best matching of clothes, the detergent and the water consumption is achieved, and the weighing method is difficult to meet the requirements of users.
The Chinese patent with the application number of 201320340304.3 discloses a washing machine with a suspension system, which relates to the field of washing machines and comprises a box body and a washing barrel, and is characterized by further comprising the suspension system, wherein the suspension system comprises suspension pins, a suspension rod, a spring sleeve, a spring seat, a weighing sensor and a sensor seat, and the suspension system is fixedly connected with the box body through the suspension pins and fixedly connected with the washing barrel through the spring sleeve; the hanger rod is hung and installed on the hanging foot; the spring sleeve, the spring seat, the weighing sensor and the sensor seat are all sleeved on the suspender; the spring suspension is arranged between the spring sleeve and the spring seat; the weighing sensor is arranged between the spring seat and the sensor seat, and the sensor seat and the suspender are relatively fixed.
Although the above structure can be accurately measured, the following defects exist: because the weighing sensor is arranged on the suspension system, the washing machine component is more complex to install, the wiring is difficult, and potential safety hazards exist; in addition, the suspension system is mainly used for damping, and the vibration of the washing barrel assembly is large in the working process, so that the pressure change of a weighing sensor arranged between the spring seat and the sensor seat is large, and the service life is shortened.
In addition, the existing vibration absorber often causes the gravity and the vibration reduction spring to be in a non-linear relation due to certain damping property of the structure of the vibration absorber, and the hanger rod spring often presses the whole machine in a water inlet state, so that the measuring range is insufficient, and the weighing of the washing machine is influenced.
Chinese patent No. 201210176786.3 discloses a laundry weight sensing device for washing machine and a method of using the same, comprising a weighing device disposed on the washing machine and a weighing circuit connected to the weighing device, wherein the weighing circuit comprises a microprocessor, a piezoresistor and a voltage-dividing protection resistor connected in series with each other and connected to the microprocessor, and the calculation is performed by the variation of the resistance value of the piezoresistor. The weighing device is positioned above the upper cover plate of the shell so as to be convenient for placing clothes. The weighing device may be an electronic balance-like weighing device.
The structure is equivalent to that the existing electronic balance is embedded above the shell of the washing machine, although the weight of clothes can be measured, the clothes must be placed on the weighing device to be measured before each time of washing, and then the clothes are put into the washing machine to be washed, so that the use of a user is very troublesome; secondly, the device cannot measure the amount of water in the washing machine.
Still some manufacturers realize the function of weighing at the washing machine footing through the installation foil gage, and install the peripheral circuit of footing structure and be difficult for connecting, walk the line difficulty, and have the potential safety hazard, thereby again because most users are used to place article on the washing machine box and lead to measuring inaccurately, perhaps need the user to move article at every turn, use inconveniently.
In view of the above, the present invention is particularly proposed.
