Problems solved by technology

[0004] The above method can be considered as, before the buckle pin protrudes from the drum lock driving part (21), the described drum of the washing machine has been accurately positioned. Therefore, the actual solution of the above technical solution is to adjust its position At the same time, it is very troublesome to set the concave part on the drum, and the drum needs to be redesigned, and there is a possibility that the strength of the drum will be reduced; if the concave part is set on the rotor of the motor, the motor also needs to be redesigned. In view of this, present invention

Embodiment 1

[0017] The positioning method described in the present invention is like this, referring to accompanying drawing 2,

[0018] Usually, when positioning is not required, the driving device 4 does not work, and the positioning buckle 5 is in a normal position, and will not contact the positioning wheel 3, as shown in (a) of FIG. 2 .

[0019] But when positioning is required, drive the electromagnet to make the drive block move forward. If the positioning hole 2 is not facing the positioning buckle 5, the positioning buckle will withstand the edge of the positioning wheel 3. Referring to (b) of Figure 2, the spring 6 is compressed. Positioning wheel 3 continues to rotate.

[0020] When the positioning hole 2 is just aligned with the positioning buckle 5, the positioning buckle 5 is inserted into the positioning hole 2 due to the action of the spring, and the roller is accurately positioned, as shown in (c) of FIG. 2 .

[0021] Considering the friction between the positioning buck...

Embodiment 2

[0024] The positioning device of the present invention includes two parts, one part is the positioning wheel 3 installed on the drum shaft, the positioning wheel is fixed on the drum shaft of the washing machine with a spline, and the positioning hole of the positioning wheel 3 and the drum door of the washing machine are connected Form a certain relative position.

[0025] The other part of the positioning device is the driving device 4, the driving device is installed on the appropriate position of the washing machine tub, the driving device includes an electromagnet (not marked in the figure), the electromagnet is used to drive When the driving block 7 moves forward or retreats, the driving block 7 and the positioning buckle 5 are connected with the spring 6 to form an elastic connection. When the driving block 7 moves back and forth, the positioning buckle 5 can be driven to move forward and backward.

[0026] A buffer device 8 is arranged on the side of the driving device...

Embodiment 3

[0035] Others are the same as in the second embodiment, except that the driving device is partially replaced by a pneumatic device, that is, the pneumatic device is used to drive the driving block to move back and forth.

[0036] Because the size of the pneumatic force can be controlled, the positioning buckle 5 can elastically bear on the positioning wheel, and when the positioning buckle falls into the positioning hole, the cylinder is locked after being positioned.

Abstract

The drum buffering locator of drum type washing machine has one locating wheel set in the proper position on the power input shaft or belt pulley and one telescopic elastic locating buckle set to the outer wall of the outer tub. During operation, the locating buckle pushes on the locating wheel elastically until the locating buckle falls into the locating hole to locate the drum of the washing machine accurately. At the same time, one buffer is set beside the locating buckle or the driving unit to reduce impact caused by the locating. Compared with available technology, the present invention has the advantages of simple structure, capacity of being used in available washing machine without need radical change, and low cost.

Description

technical field [0001] The invention relates to a positioning device, in particular to an inner tub buffer positioning device for a drum type washing machine. Background technique [0002] CN03105194.4 discloses a drum type washing machine which uses a simple structure to fix the rotation position of the drum. An engagement groove (25) is provided on the outer periphery of the rotor (20b) of the external gear motor directly connected to the main shaft (14) of the drum (13), and a drum locking device (21) is provided directly below the shaft. . The drum locking device (21) has a structure to move the lock pin vertically with the rotation of the torque motor, and the position of the drum (13) is fixed when the lock pin advances to fit in the groove of the engagement groove (25). [0003] CN200410034795.4 discloses a drum-type washing machine. In the drum-type washing machine, an opening for putting in laundry is provided on the peripheral surface of the drum, and the operati...
