The disclosure relates to the field of washing machines, and more particularly to a vibration squeeze drum washing machine.
Conventional drum washing machines include a drum wall and a lifting rib disposed on the drum wall. The clothes are lifted by the lifting rib to a certain height and then falls off to produce tumbling and friction effect, thus achieving the purpose of washing the clothes. However, the washing mode is time-consuming, and the washing effect is not good. Thus, developing a novel drum washing machine with new structure has become one of the hot spots in the field of washing machine technology.
To overcome the above mentioned defects, there provided is a vibration squeeze drum washing machine that has a simple structure and adopts a combination washing mode of vibration and squeeze.
To achieve the above objective, the following technical solutions are adopted.
Provided is a vibration squeeze drum washing machine, comprising a housing, a barrel, a drum, a machine door, a vibration squeeze device, a turnover mechanism, a mechanical vibrator, a position sensor, a drum motor, a drive device, a water intake valve, a drainage valve, and a control system. The vibration squeeze device is disposed on the inner side of the machine door and is located in a recess of an observation window of the machine door.
As an improvement, the vibration squeeze device is connected to the machine door via the turnover mechanism. The turnover mechanism enables the vibration squeeze device to turn up and down at 90 degrees relative to the door.
In the upturning position, the axis of the vibration squeeze device is parallel to the machine door.
In the downturning position, the axis of the vibration squeeze device is perpendicular to the machine door, and the vibration squeeze device extends into the lower part of the drum.
As an improvement, the turnover mechanism comprises a motor, a worm, and a worm wheel; the worm is connected to the worm wheel; the motor is connected to the worm; the worm wheel is connected to the vibration squeeze device; the motor drives the worm to rotate to realize the vibration squeeze device to overturn.
As an improvement, the vibration squeeze device is connected to the worm wheel via an elastic part, so that the vibration squeeze device can oscillate elastically when encountering large resistance.
As an improvement, the position sensor is disposed on the machine door; the level signal of the position sensor is input to the input end of the control system to accurately sense the overturn state of the vibration squeeze device.
As an improvement, the vibration squeeze device comprises an inner chamber and a mechanical vibrator disposed in the inner chamber; the connection and disconnection of the power supply of the mechanical vibrator are controlled by the control system of the washing machine. The vibration squeeze device can be either a vibrator specially designed for the washing machine or a general industrial vibrator.
As an improvement, the vibration squeeze device further comprises a plurality of raised vibration heads.
The configurations of the vibration squeeze drum washing machine, such as water intake, water drainage, water level control, clothing weight and dehydration balance adjustment, are basically the same as that of the existing drum washing machines.
The laundry process of the vibration-squeeze type drum washing is different from that of the existing drum washing machines. The washing of clothes is mainly accomplished by the vibration squeeze device extending into the drum. The main function of the rotation of the drum is to overturn the clothes in the washing and rinsing process and dehydrate the clothes in the dehydration process.
Only when the vibration squeeze device is in the upturning vertical position can the drum rotate. Only when the drum stops rotation completely does the vibration squeeze device turn downwards and extend into the drum. It is the vibration squeeze device that turns downwards into the drum to vibrate, extrude, and wash the clothes.
After finishing vibrating, squeezing, and washing the clothes once, the vibration squeeze device will turn up automatically. After the vibration squeeze device is turned up in place, the drum rotates several times at low speed to overturn the clothes.
After rotating several circles, the drum stops rotating, and the vibration squeeze device turns downwards and vibrates again . . . . Several circles (preset by the procedure) later, the washing process is completed.
After the washing process, the water is filled in and drained out of the washing machine for several times, the drum rotates for several times at intervals, and the vibration squeeze device also turns downwards and vibrates for several times to rinse the clothes.
After the rinsing process, the vibration squeeze device stays in the upturning position, and the drum rotates rapidly to dehydrate the clothes.
After the dehydration process, the washing machine sends out a warning tone reminding that the laundry process has been completed, and then open the machine door and take out the laundry.
Advantages of the vibration squeeze drum washing machine of the disclosure are summarized as follows:
(1) The vibration squeeze drum washing machine improves the washing cleanliness, shortens the running time and reduces the power consumption. Compared with the existing drum washing machines, the vibration squeeze drum washing machine has better washing cleanliness and better energy-saving effect.
(2) The existing drum washing machines utilize the rotating inner drum to lift up the clothes to a certain height and then drop the clothes to achieve the washing effect. Only when the diameter of the drum is large enough can the clothes be raised to the required height. The vibration squeeze drum washing machine of the disclosure achieves the washing effect by vibrating and squeezing the clothes, so that the diameter of the drum can be reduced, the overall size of the drum washing machine can be reduced, and so can the overall weight of the drum washing machine.
To further illustrate, embodiments detailing a vibration squeeze drum washing machine are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.
As shown in
The turnover mechanism 6 comprises a motor 6-1, a worm 6-2, and a worm wheel 6-3; the worm 6-2 is connected to the worm wheel 6-3; the motor 6-1 is connected to the worm 6-2; the worm wheel 6-3 is connected to the vibration squeeze device 5. When the motor 6-1 rotates in one direction or in the opposite direction, through the transmission of the worm 6-2 and the worm wheel 6-3, the vibration squeeze device 5 can turn up or down, as shown in
In addition to the worm and the worm wheel mechanism, the turnover mechanism 6 can also adopt a deceleration step motor or a deceleration servo motor. The rotating shaft of the deceleration step motor or the deceleration servo motor is directly connected to the rotating shaft of the vibration squeeze device 5.
The vibration squeeze device 5 further comprises a plurality of raised vibration heads 5-1 so as to improve the vibration and squeeze effect upon contacting the clothes.
The vibration squeeze device is connected to the worm wheel 6-3 via an elastic part 6-4, so that the vibration squeeze device 5 can oscillate elastically when encountering large resistance, as shown in
