Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
The invention provides a vibration absorption device for a drum of a clothes drier, which is sleeved on the side surface of a drum 1 and comprises two symmetrical half-moon-shaped vibration absorption units, a transmission unit and a trigger unit.
Each vibration absorbing unit includes an upper turntable 2 and a lower fixed disk 3. The upper turntable 2 comprises a protruding cylindrical block 21 arranged in the middle and three concave structures uniformly arranged on the outer edge of the upper turntable, a buffer layer 22 is arranged on the inner edge of the upper turntable 2, the buffer layer 22 is made of rubber or natural rubber and the like, the buffer layer 22 can protect the roller 1, the roller is not easy to be excessively impacted, and the phenomenon that the upper turntable is clamped with the roller due to excessive rotation can be avoided.
The lower fixed disk 3 comprises a hollowed arc-shaped groove 31 arranged in the middle and a hollowed groove 32 matched with the concave structure, and a spring is arranged in the hollowed groove 32 in a protruding mode. Preferably, the length of the hollowed out groove 32 may be slightly less than the length of the concave structure to facilitate the concave structure to reciprocate at the spring within the hollowed out groove 32. One end of the lower fixed disc 3 is provided with a protruding ring 33 for fixedly connecting with the laundry dryer while allowing the vibration absorbing unit to hinge around the ring 33, and the other end is provided with a protrusion and a concave groove, preferably, a spring is provided in the concave groove. The upper turntable 2 is buckled above the lower fixed disk 3, the diameter of the cylindrical block 21 is equal to the width of the arc-shaped groove 31, the cylindrical block 21 can slide in the arc-shaped groove 31, and the concave structure reciprocates at the spring in the hollow groove 32.
The transmission unit comprises a scissor lever 4, an arc frame 5 and a swivel lever 6. The scissor lever 4 comprises a first end, a second end, a third end and a fourth end, wherein the first end and the second end of the scissor lever 4 are provided with small protruding blocks which can be arranged in the arc-shaped frame 5 to slide and are connected with the arc-shaped frame 5 through springs, and the third end and the fourth end of the scissor lever 4 are connected with the protruding blocks on the lower fixing disc 3 through hinges. The rotating lever 6 comprises a first end and a second end, the first end of the rotating lever 6 is located below the trigger unit and spaced apart, and the second end of the rotating lever 6 is fixedly connected with a wedge block 61. The wedge 61 is located between the first and second ends of the scissor lever 4 when the shock absorber is not in operation.
The triggering unit comprises a push rod 7, the push rod 7 is an electric push rod and is controlled by a triggering circuit, and when the vibration absorption device does not operate, the push rod 7 is positioned above the first end of the rotating lever 6 and has a spacing distance.
The working principle is as follows:
when the fact that the spin dryer is about to finish running is detected, the trigger circuit sends out an instruction, the electric push rod pushes the first end of the rotating lever to move downwards, the second end of the rotating lever and the wedge-shaped block sleeved at the second end of the rotating lever move upwards together, the wedge-shaped block is pulled away from the arc-shaped frame, the shear-type lever is rapidly drawn towards the middle under the action of the force of the spring in the arc-shaped frame at the upper end (the first end and the second end) and the spring connected with the lower fixing disc at the lower end (the third end and the fourth end), accordingly, the upper rotating disc of the vibration absorption unit is in contact with the roller, the shear-type lever is driven to do shear-fork type movement, and the. Because the mass of the fixed disc at the middle lower part of the vibration absorption unit is larger, the vibration of the roller is effectively weakened by utilizing the vibration absorption principle.
When the scissors type wedge block is used again, the upper ends (the first end and the second end) of the scissors type levers are pulled along the arc-shaped frame, the springs for connecting the arc-shaped frame and the upper ends (the first end and the second end) of the scissors type levers are compressed, and the wedge block returns to the original position again, namely is clamped between the first end and the second end of the scissors type levers to wait for being excited again.
It is envisaged that the vibration absorbing apparatus of the present invention may be used not only in a clothes dryer but also in a washing machine.
The technical principles of the present invention have been described above in connection with specific embodiments, which are intended to explain the principles of the present invention and should not be construed as limiting the scope of the present invention in any way. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive efforts, which shall fall within the scope of the present invention.
