Description
Technical field
The present invention relates to drum type washing machine, specifically is a kind of lifting device of barrel roll laundry machine.
Background technology
General washing machine mixes washings and washing agent in washing together, and the device that washing is braked as washings can be divided into vertical, cabinet type according to structure, drum-type etc.This kind washing machine is the gyroaxis horizontal positioned drum, and door opening is changed in the cabinet front.
The vertical profile side view of the old-fashioned barrel roll laundry machine major part of Fig. 1.
Old-fashioned barrel roll laundry machine is that door (1) is opened on casing (2) front, outer bucket (4) places its inboard, and bucket is provided with gyroaxis (7) in (4) washings and washing agent is put in the drum (10) outside, motor (6) is set up and with on gyroaxis is connected in bucket (a 4) back outside, in order to allow outer bucket (4) and casing (2) inboard stay certain flowing space, box inside and outside barrel between load onto support bar (8).
This kind barrel roll laundry machine is with drum (10), casing (2) and outer bucket (4) place the front to come opening simultaneously, motor (6) and gyroaxis (7) are arranged at rear outer wall, set up tripod bow (9) in the gyroaxis end, bow is connected drum (10) rear portion with outer bucket.
Install with this, motor (6) rotates, and drum (10) will carry out the horizontal rotation washing with gyroaxis (7).
Place several lifting devices of giving prominence to the centre of gyration (12) in the inboard of drum (10), when drum (10) was rotating, lifting device upwards promoted washings, had increased flowing of washings, and clean result is strengthened.
The side view and the bottom view of old-fashioned barrel roll laundry machine lifting device of Fig. 2 Fig. 3 and drum, Fig. 4 are the structural representations of the A portion of Fig. 2.
As shown in Figure 1 and Figure 2, lifting device (12) is connected on drum (10) inwall, and outstanding to the centre of gyration direction that places bow (9) end horizontal to place.Drum (10) revolution, lifting device just upwards promotes washings, increases flowing of washings.
Lifting device (12) is connected on the contact-making surface of drum (10) inwall with several bloated hatpins (18), bow (9) then is screwed on drum (10) rearward end.
The action of the old-fashioned barrel roll laundry machine that constitutes by method above-mentioned is as follows.
At first, by the opening door (1) of casing (2), after washings and washing agent put into, connect power supply, motor is started working, and drum (10) begins revolution.
At this moment, washings is run into the lifting device (12) that is arranged at drum (10) inwall, and along with the revolution of drum, lifting device takes washings to the drum upside.Then, washings just breaks away from lifting device (12) after rising to a certain degree, on one side to the whereabouts, flows on one side, reaches clean result.
But, old-fashioned barrel roll laundry machine will be fixed on the drum inboard to the lifting device of washing machine with the hatpin (18) that expands, bow will be screwed at drum bottom surface outer wall, and assembly process is very complicated, and the connecting elements cost that requires to assemble lifting device and bow respectively can not reduce.
And the drum wall of solid memder is loaded onto several lifting devices, and its rear portion refills bow, and its bonding strength is not high yet, and long operational time also can produce the problem of be full of cracks on drum.
Summary of the invention
The present invention will be screwed at drum bottom surface outer wall for solving above-mentioned old-fashioned barrel roll laundry machine bow, assembly process is very complicated, and the connecting elements of lifting device and bow is assembled in requirement respectively, the problem of technology such as cost can not reduce proposes, and a kind of lifting device of barrel roll laundry machine is provided for this reason.
A kind of lifting device of barrel roll laundry machine, comprise opening door casing the preceding, outer bucket is arranged at box inside, outer bucket inner horizontal is placed the drum that gyroaxis washs, the bow that is connected with the motor gyroaxis of drum rear side outer wall, be arranged at the lifting device that the drum inboard is flowed the washings vertical direction, it is characterized in that above-mentioned lifting device and bow are loaded on the drum together by connecting elements.
Effect of the present invention is, be connected the end of lifting device and bow on the drum together, finished the assembly process of lifting device and bow device simultaneously, reduced installation time, and lifting device and bow device have also reduced cost as a connecting elements production, the inside and outside wall that lifting device and bow are fixed in the drum rear side has simultaneously also strengthened bonding strength, makes the drum safe handling avoid distortion or broken.Not only improved and be arranged at the lifting device that the drum inboard can strengthen the washings liquidity.And lifting device and the spiral pivot that is contained in the drum back link together and make barrel roll laundry machine make the engineering unification.In addition, bow and lifting device are connected in the drum between the outside with screw, and the turning power of motor directly passes to the noise that lifting device has reduced drum, have also prevented drum distortion and damaged, reach safe operation.
