SUMMARY OF THE INVENTION The present invention relates to an operation for fixing an outer tub to a gantry at the time of packing during transportation and an operation for separating and supporting the outer tub from the gantry when unpacking and installing. It is something that simplifies.

[0006]

A solution of the present invention is to dispose a drum and its outer tub in a main body frame installed on a gantry, and to arrest the outer tub from below with a vibration-proof air spring. While elastically supporting and providing an engaging portion on the outer tank side,
The outer side by the exhaust from the air spring is
A configuration is provided in which the engaged portion engages when the tank is lowered .

[0007]

[Effect] At the time of packing during transportation, the air of the air spring is released. Then, the outer tank and the gantry are lowered by their own weight, and the engaging part and the engaged part of the outer tub and the gantry are engaged with each other, so that they are fixed to the gantry.
When unpacking and installing, the air spring is blown with a predetermined compressed air to raise the outer tub and disengage.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS.

Reference numeral 1 denotes a frame of a main body of the washing and dehydrating machine. An operation opening 2 is provided on a front surface, and a bottom portion is fixed to a gantry 3. Reference numeral 4 denotes an outer tub installed in the main body frame 1, and reference numeral 5 denotes a drum 5 which is rotatably supported on one side in the outer tub 4 and has a dewatering hole on a peripheral wall. The outer tub 4 has a front plate 6A and a rear plate 6A fixed to the front and rear surfaces thereof as flanges, and a rear plate 6A has a bearing portion 7 for supporting the drive shaft of the drum 5 and a motor. 8A
The motor room 8 accommodating the above is mounted. This motor 8A
Is decelerated by the pulley and the belt and transmitted to the rotating shaft of the drum 5. 9.9A are air springs disposed at two places on the front side and one place on the rear side of the gantry 3, and are fixed to the upper surface of the gantry 3 and the L-shaped metal fittings 10 at the lower part of the outer tub 4 and compressed. By enclosing the air, the outer tank 4 is elastically supported from below. A door device 11 is attached to the outer tank front plate 6 so as to be openable and closable, and a door handle 12 for opening and closing the door device 11 is provided.

Reference numeral 13 denotes a plurality of engaging portions A and 14 formed by extending the lower end of the outer tank front plate 6 downward and forming triangular projections. Arrange,
The engaged portion A is provided to face the engaging portion A13. Reference numeral 15 denotes an L-shaped engaging portion B, 17 fixed downward to the motor chamber 8 on the side of the outer tub 4 and provided with a through hole 16 in the horizontal side. Part B (engaging projection).

In a normal installation state, each of the air springs 9 is filled with about 3 kg / cm ² of compressed air.
The air spring 9A is filled with compressed air of about 5 kg / cm ² , which supports the outer tub 4 as a whole in an anti-vibration manner.
3, B16 and the engaged portions A14, B17 are separated from each other.

When packing and transporting, air is extracted from the air springs 9 and 9A and contracted. Then, outer tank 4
At the two front positions, the engaging portion A14 and the engaged portion A13 are engaged and held, and at the two rear positions, the engaging portion A14 is engaged with the through hole 16 provided in the engaging portion B15. The part B (engaging projection) 17 is inserted to be engaged. Therefore, any engagement holding state such as the gantry 3 and the outer tub 4 can be obtained (see FIGS. 2 to 4).

As described above, the air springs 9 and 9A for vibration isolation are used at the time of packing without using packing metal fittings or fixing bolts.
The outer tub 4 can be engaged and held (fixed) only by bleeding (shrinking) the air. At the time of unpacking and installation, a predetermined amount of compressed air is sent to the air springs 9 and 9A by pressure to expand the air springs 9 and 9A so that the air springs 9 and 9A are disengaged from each other.

A second embodiment will be described with reference to FIGS. 1 to 4 are denoted by the same reference numerals, and description thereof will not be repeated.

Each of the figures shown here shows a state of packing during transportation. Reference numeral 20 denotes an engaging piece provided at the lower left and right ends of the front plate 6 by being bent in the depth direction. An insertion hole 21 is provided substantially at the center. Further, the mount 3 is provided with a fixing hole 22 corresponding to the insertion hole 21.

Reference numeral 24 denotes a holding piece vertically provided on both side walls of the motor chamber 8 on the side of the outer tub 4 , and an insertion hole 25 is provided at a substantially central portion of the holding piece 24. Further, a fixing hole B26 corresponding to the insertion hole 25 is provided in the gantry 3. And air spring 9.
When the engagement piece 20 and the holding piece 24 are inserted downward through the holes on the gantry 3, the lock rods A23, B
27 is inserted into the insertion hole 21 and the fixing hole 22, the insertion hole 25 and the fixing hole B26, and is engaged therewith.

When the washing and dewatering machine is installed and put into use, the lock bars 23 and 26 are pulled out, and the air springs 9 and 9A are filled with a predetermined amount of compressed air in the same manner as in the first embodiment.
The outer tub 4 is lifted as described above, and is supported by the air springs 9 and 9A.

As described above, also in the second embodiment, at the time of packing, the air is removed from the air springs 9 and 9A, and the lock bars 23 and 27 are inserted into the respective holes to hold the engagement, and to be engaged in the front-rear and left-right directions. Restrict the movement of Lock rod 2 at installation
By pulling out 3 and 27, the engaged and held state can be released. After that, by sending a predetermined amount of compressed air to the air springs 9 and 9A, the work of packing and installation can be easily performed in a short time.
Anti-vibration support by the air springs 9 and 9A can also be performed.

[0019]

According to the present invention, the compressed air is extracted from the vibration-preventing air spring, or the outer tub and the gantry are engaged and held by releasing air, or released. The workability during packing and installation can be improved.
