Abstract

The present invention discloses an isolated type washing machine inner drum locking device, comprising an open inner drum door, a fixed inner drum door, a supporting mechanism and a locking mechanism. The unlocking unit rotates to drive the lock seat to rotate, so that the arc-shaped limit rod pulls the telescopic rod to contract, so that the locking groove member is separated from the triangular clamping plate and the door locking clamping seat at the upper end of the open inner drum door, so that the open inner drum door is opened, and the inner drum door can be effectively self-locked and closed, so that the inner drum door will not shake. The triangular clamping plate is clamped in the locking key groove. When the inner drum door rotates at a high speed during operation, the greater the centrifugal force generated by the rotation of the inner drum door, the more the locking key groove of the locking groove member is clamped with the triangular clamping plate. The locking key groove of the locking groove member can play a role of fixing and further locking the inner drum door when the inner drum door is locked and rotates, so that the two inner drum doors are extremely fixed. When in use, the two inner drum doors will not fall off when the inner drum rotates at a high speed, thereby ensuring the overall use.

Description

Technical Field

[0001] The invention relates to the technical field of washing machines, and in particular to an isolated washing machine inner drum locking device. Background Art

[0002] The concept of the isolation type washing machine is to divide the laundry room into two independent operating areas: the clean area and the non-clean area. The laundry is loaded through the machine door located on the non-clean area side, and taken out from the machine door located on the clean area side after washing. It prevents cross contamination caused by loading and unloading laundry from the non-clean area, and is an ideal washing equipment for dust-free industrial and hospital laundries. The hygienic isolation type washing machine is fully suitable for pharmaceutical factories, hospitals, sanatoriums, virus and microbiology laboratories, electronics factories, food processing plants, oil platforms and other industries. The existing isolated washing machine inner drum structure is unreasonably designed. The washing machine inner drum usually adopts an inner drum door that can be opened up and down. After adding the objects to be cleaned, the two inner drum doors are closed by being connected up and down by latches or hooks. When the two inner drum doors are pushed, they will still shake against each other, and the fixation is poor. When in use, the two inner drum doors are very likely to fall off under high-speed rotation, affecting the overall use. The greater the centrifugal force, the easier it is to cause the lock pin to be insufficiently strong and break, resulting in an accident, causing the two inner drum doors to flip inward and damage the door lock structure. Therefore, it is urgent for technical personnel in this field to design an isolated washing machine inner drum locking device. Summary of the invention

[0003] The problem to be solved by the present invention is that the rotation of the lock seat is driven by the rotation of the unlocking unit, so that the arc limit rod pulls the telescopic rod to retract, and the telescopic rod retracts, thereby driving the spring clamp seat to retract through the tension spring, and the spring clamp seat drives the locking groove member to retract, so that the locking groove member is separated from the triangular clamp plate and the lock door clamp seat at the upper end of the open inner drum door, thereby opening the open inner drum door, and can effectively realize the self-locking and closing of the inner drum door, so that the inner drum door will not shake, and the triangular clamp plate is clamped in the locking key slot. When the inner drum door rotates at a high speed during operation, the greater the centrifugal force generated by the rotation of the inner drum door, the more the locking key slot of the locking groove member fits the triangular clamp plate, and the locking key slot of the locking groove member can play a role in fixing and further locking the inner drum door when the inner drum door is locked and rotates, so that the two inner drum doors are extremely fixed, and when in use, the two inner drum doors will not fall off when the inner drum rotates at a high speed, thereby ensuring the overall use of the isolated washing machine inner drum locking device.

[0027] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are described in detail below through specific usage methods.

[0028] The specific working process is as follows: when in use, the unlocking piece 401-1 of the unlocking unit 401 of the locking mechanism 4 in the limiting cavity groove 5 of the fixed inner cylinder door 2 is inserted into the core groove 401-4 of the unlocking core shaft 401-3, and the limiting protrusion 401-2 at the bottom end of the unlocking piece 401-1 presses the pin 401-8 downward, so that the pin 401-8 and the long axis 401-7 and the telescopic spring 401-6 below shrink downward, and then the operator holds the unlocking piece 401-1 and rotates it clockwise, so that 401-1 rotates the unlocking core shaft 401-3, and the unlocking core shaft 401-3 drives the rotating shaft 401-11 to rotate, and the rotating shaft 401-1 1 rotates to drive the lock seat 402 to rotate, so that the arc-shaped limiting rod 403 pulls the telescopic rod 404 to contract, and the telescopic rod 404 contracts, thereby driving the spring clamping seat 406 to contract through the tension spring 405, and the spring clamping seat 406 drives the locking groove 407 to contract, and the locking groove 407 is separated from the triangular clamping plate 408 and the door locking clamping seat 6 at the upper end of the open inner cylinder door 1, and the door locking clamping seat 6 leaves the limiting cavity groove 5, so that the open inner cylinder door 1 is opened, and the operator puts the cleaning object into the open inner cylinder door 1. The rotation of the 401-11 rotating shaft will drive the first connecting rod 301 and the second connecting rod 302 of the supporting mechanism 3 to swing upward, and the second connecting rod 302 of the supporting mechanism 3 will swing upward. The connecting rod 302 drives the threaded rod 304 and the second connecting sleeve 305 to move toward one end, thereby driving the supporting connecting arm 306 and the limiting spring 308 to elastically contract, and the supporting mechanism 3 elastically supports the locking mechanism 4. Then the operator closes the open inner cylinder door 1, and the door lock holder 6 enters the limiting cavity groove 5. Then the operator holds the unlocking piece 401-1 and rotates it counterclockwise. The limiting protrusion 401-2 at the bottom end of the unlocking piece 401-1 is retracted upward to make the extrusion pin 401-8 and the long axis 401-7 and telescopic spring 401-6 below return to their original positions, and the rotating shaft 401-11 rotates in the opposite direction. The rotating shaft 401-11 rotates in the opposite direction to drive the lock The rotation of the seat 402 causes the arc-shaped limiting rod 403 to pull the telescopic rod 404 to extend. The telescopic rod 40 extends, thereby driving the spring clamping seat 406 to extend through the tension spring 405. The spring clamping seat 406 drives the locking groove part 407 to extend. The locking groove part 407 is inserted into the locking door clamping seat 6 at the upper end of the open inner drum door 1. The locking key groove 409 of the locking groove part 407 is inserted into the triangular clamping plate 408, thereby locking the open inner drum door 1 and starting the washing machine to wash. When the inner drum door rotates at a high speed during operation, the greater the centrifugal force generated by the rotation of the inner drum door, the more the locking key groove 409 of the locking groove part 407 fits the triangular clamping plate 408 and is clamped.
