Problems solved by technology

[0003] 1. The impact hammer is always in the inner tub of the washing machine, which makes it inconvenient to pick and place clothes
[0004] 2. The impact hammer and its stroke are enlarged, the guide mechanism is bulky, and the vertical dimension is large. In order not to collide with the inner tub when drying clothes, the impact hammer must be raised to a height higher than the inner tub opening, which will inevitably increase the height of the washing machine. Increase, or reduce the height of the inner barrel

Abstract

A heavy hammer heating type sleeved-drum washer is disclosed. The beating hammer moving down by gravitation is installed to the lower end of a multi-class telescopic sleeve tube suspended from the center of cover. When the cover is opened, the hammer is vertically withdrawn in the cover by a 4-connecting-rod mechanism. Under the drive of motor, crank rockerarm, gear, rope wheel and steel cable, the hammer is moving up and down to beat the clothes while the internal is rotating in step mode.

Example Embodiment

[0027] Example
[0028] figure 1 It is a structural diagram of a heavy hammer-beating washing machine. It does not show the inlet and outlet drainage mechanism, water level control mechanism, shock absorption mechanism, electrical control and other mechanisms. The height of the washing machine is about 85 cm, which is equivalent to a general 4.2 kg fully automatic sleeve washing machine. Among them, the motor 28 has three speeds, corresponding to the beat frequency of 120 times, 60 times, and 30 times per minute. The motor 38 also has three speeds, which correspond to the continuous rotation of the inner drum at 800 revolutions per minute and 100 revolutions per minute through the pulley and each time it passes through the ratchet. It rotates in steps of 2 revolutions per minute. The working principle of each component is explained below in conjunction with a washing process.
[0029] 1. Stop state: the highest point positioning contact 22 of the rope sheave 24 is located at the position of the positioning relay 23, the motor 28 is in the braking state, the rope sheave has pulled the hammer to the highest point, and the telescopic sleeve 11 is retracted to one section. the height of. The drain valve solenoid is not energized, and the drain valve controlled by it is closed. The control electromagnets of the two two-way clutches 34 are also not energized, and their middle half-clutches are kept engaged with the lower two half-clutches under the action of springs.
[0030] 2. Put in the clothes: press the door lock and uncover the cover. During the cover opening process, the hammer and the telescopic sleeve will always remain in the vertical direction and will be lifted and moved closer to the cover. When the cover is opened to the vertical In the straight direction, half of the hammer and the telescopic sleeve retract into the cover. The torsion spring 17 fitted on the hinge shaft 13 of the machine cover is used to balance the clockwise torque of the hammer and the telescopic sleeve. After the machine cover is opened, the mouth of the inner tub is opened. At this time, clothes and detergent can be put in, and then the machine cover is closed, and the operating power cord is connected by the safety door lock.
[0031]3. Select the washing program: first press the power switch to turn on the power, and then select heavy, medium, and light washing according to the degree of soiling of the clothes on the control panel, respectively corresponding to 120 strokes and 60 strokes per minute during washing and rinsing operations , 30 beats. The input amount of clothes is more, medium and less, corresponding to 22 liters, 16 liters, and 10 liters of water respectively. It is assumed that the medium wash and the amount of laundry are medium.
[0032] 4. Water injection: The water injection solenoid valve is turned on, and water is injected into the bucket. When the water is filled to the required 16 liters, the water level controller sends a signal to the control system, and the control system cuts off the power supply of the water injection electromagnet, and the water injection stops.
[0033] 5. Washing:
[0034] (1) Clothes wetting and finishing: turn on the two-way clutch to control the electromagnet and the power of the motor 38. The inner tub drive motor drives the inner tub through a pulley to rotate forward and backward three times at 100 revolutions per minute. Each time the motor 38 is turned on for a few seconds immediately When disconnected, the inner tub rotates forwards and backwards for a short time, so that the clothes are wetted and distributed more evenly, and then the two-way clutch control electromagnet and the power of the motor 38 are disconnected.
[0035] (2) First beat: Cut off the power of relay 23 to make it in a non-functional state, turn on the power of motor 28 and motor 38, motor 28 drives crank and rocker 27 to continuously rotate, crank rocker 27 drives big gear 26 to 90 °Swing, the big gear 26 drives the small gear 25 and the rope wheel 24 to swing 180°, and the rope wheel drives the hammer up and down through the wire rope, according to the set striking frequency of 60 times per minute. Since the middle half-clutch of the clutch 34 maintains the engaged state with the two half-clutches below, the motor 38 that is started at the same time drives the inner barrel to rotate step by step at a speed of 2 revolutions per minute through the crank 35, the rocker 36, the ratchet 37, and the inner barrel shaft 39. The movement of the two motors should be adjusted until the percussion hammer is lifted off the clothes and the inner tub rotates one step further. After beating for 2 minutes, the power of the relay 23 is switched on to restore its function, and the hammer rises to the highest point corresponding to the contact 22. When the relay 23 is activated by the contact 22, the power supply of the motor 28 and the motor 38 are cut off, and the hammer stays at the highest point.
[0036] (3) Flip the clothes: turn on the power of the two-way clutch electromagnet so that the motor 38 can drive the inner tub to rotate through the pulley. Turn on the power of the motor 38 and drive the inner tub to rotate 3 times in the required direction at 100 revolutions per minute, each lasting 3 times Within seconds, water will pour in from the center of the inner tub to push the clothes over. Then disconnect the motor 38 and the two-way clutch electromagnet power supply.
[0037] (4) The second beat: Repeat the action of (2) above.
[0038] 6. Dehydration after washing: the drain valve is opened to start draining water, and the water level control mechanism starts to work. After receiving the information that the water has been drained, wait for another 30 seconds, turn on the motor 38 and the two-way clutch control electromagnet power supply, and the motor 38 drives The inner barrel has been rotated at 800 revolutions per minute for 2 minutes.
[0039] 7. The first rinsing: close the drain valve, open the water filling valve, and then repeat the operations of the 4th item and the 5th washing (1) and (2), that is, the beating time is 2 minutes.
[0040] 8. Dehydration after the first rinsing: Repeat the operation of the previous 6.
[0041] 9. The second rinsing: repeat the operation of 7 above.
[0042] 10. Final dehydration: Repeat the operation of 8 above, but the rotation time of the inner barrel is 3 minutes. Then the buzzer emits a musical sound to notify the end of the washing program. At this time, you can open the cover to take out the clothes.
