Description

Description: FIELD OF THE INVENTION The present invention relates to a silent washing machine.

Conventional technology In recent years, in the social situation where the concern about noise is increasing,
Noise reduction of home electric appliances having a motor such as a washing machine is drawing attention.

Conventionally, since the bottom of the washing machine main body of the washing machine is open and the leg has a gap, the inside and outside of the washing machine main body communicate with each other with a large area.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described conventional configuration, the sound generated from the motor and other drive-related parts at the time of washing and dehydrating,
It has a drawback that it propagates to the outside of the washing machine body through the gap between the bottom and the legs of the washing machine body and significantly increases the noise level.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a washing machine that lowers noise levels during washing and dehydration to reduce noise and facilitates packaging when transferring to a washing machine.

Means for Solving the Problems In order to achieve this object, a washing machine of the present invention provides an inner tub having a stirring blade inside, an outer tub in which the inner tub is installed, and an outer tub that surrounds the outer tub. A washing machine main body in which the above is elastically suspended, a transmission mechanism section and a motor for transmitting a rotational force to the stirring blades and the inner tub, and a transfer tool provided at the bottom of the outer tub so as to face the bottom opening of the washing machine main body. And to close the bottom opening of the washing machine main body when installing the washing machine to block the sound generated inside the washing machine main body and to hold the transfer tool with the packing material through the bottom opening of the washing machine main body when packing the washing machine. And a sound insulation plate to be removed from the bottom opening of the washing machine body.

Function With this configuration, the sound generated from the motor and other drive-related parts during washing and spin-drying is shielded by the sound insulation plate provided in the bottom opening of the washing machine body, significantly reducing the noise level and reducing noise. Will be stripped.
Also, when packing for transporting the washing machine, the sound insulation plate can be removed from the bottom opening of the washing machine main body, and the transfer tool can be held by the packing material through the bottom opening of the washing machine main body, which facilitates packing when transferring the washing machine. It can be done.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a washing machine main body which surrounds an outer tub, which will be described later, and has a bottom opening 1a at the bottom. Reference numeral 2 is a support portion attached to the main body 1 of the washing machine. Reference numeral 3 denotes an outer tank having an inner tank, which will be described later, which is elastically suspended from the support portion 2 by a suspension 4 having a spring and a damper. Reference numeral 5 denotes an inner tub, which doubles as a washing machine and a dehydrating tub. 6
Is a stirring blade provided on the inner bottom of the center of the inner tank 5. Reference numeral 7 denotes a transmission mechanism portion that transmits a rotational force to the stirring blade 6 and the inner tub 5, and internally includes a reduction gear for washing and a switching clutch for washing and dehydration. Reference numeral 8 denotes a motor, which applies a rotational force to the transmission mechanism section 7. A transfer tool 9 is provided at the bottom of the outer tub 3 and faces the bottom opening 1 a of the washing machine body 1. Reference numeral 10 denotes a sound insulating plate that is provided at the bottom of the washing machine main body 1 by opening and closing the bottom opening 1a so as to insulate sound generated in the washing machine main body 1. In this embodiment, a magnet 11 is provided on the upper surface of the outer periphery of the sound insulating plate 10, and the sound insulating plate 10 is attached to the bottom of the washing machine body 1 from below by a magnetic force such that the sound insulating plate 10 does not drop by its own weight.

The operation of the washing machine configured as described above will be described below.

For washing, put laundry and washing water in the inner tub 5, and transfer mechanism 7
The switching clutch is set to the washing side, and the rotation of the motor 8 is transmitted to the stirring blade 6. Next, dehydration is performed by setting the switching clutch of the transmission mechanism unit 7 to the dehydration side and transmitting the rotation of the motor 8 to the inner tank 5. At the time of washing or dehydration described above, a sound or the like generated by the drive of the motor 8 or the transmission mechanism portion 7 is generated, but since the sound insulating plate 10 is attached to the bottom portion of the washing machine main body 1 in the present embodiment, washing is performed. The sound generated from the inside of the machine body 1 is blocked, and the noise level to the outside is made extremely low.

As described above, according to the present embodiment, since the sound insulating plate 10 is attached to the bottom of the washing machine main body 1 with a magnetic force that does not drop by its own weight, the internal sound of the washing machine main body 1 is shut off and the noise level is significantly increased. Can be low. In this case, the presence of the small holes 18 does not affect the sound insulation characteristics to the left. further,
Since the main body 1 of the washing machine and the sound insulating plate 10 are attached by magnetic force, the sound insulating plate 10 can be easily attached and detached and can be dealt with when the washing machine is transported. That is, in order to prevent the washing machine main body 1 and the outer tub 3 from colliding with each other during transfer of the washing machine, the upper part of the outer tub 3 is held by the inner surface of the inner tub 5 during packing, and the lower part is passed through the bottom opening 1a. The outer tank 3 can be fixed by holding the bottom of the transfer tool 9 with a packing material. Therefore, at the time of transfer, the conventional packing method can be used as it is. The sound insulation plate 10 may be removed from the washing machine body 1 at the time of packaging for transportation, and the sound insulation plate 10 may be attached to the washing machine body 1 when the washing machine is installed.

In the embodiment, the sound insulating plate 10 is not limited to its shape, and may be a simple flat plate. Further, in the embodiment, it is also included in the present invention to extend the bottom of the washing machine body 1 from the surroundings and reduce the size of the sound insulating plate 10 so as to reduce the area of the bottom opening 1a of the washing machine body 1. .
Further, in the embodiment, the sound insulation plate 10 for the washing machine body 1 is used.
Various attachment methods other than magnetic force can be considered.

As described above, according to the present invention, by closing the bottom opening of the washing machine main body and providing the sound insulation plate, the sound insulation plate can insulate the internal sound, and the noise level can be remarkably lowered. A washing machine can be provided. Further, by removing the sound insulating plate, the transfer tool can be held by the packing material through the bottom opening of the main body of the washing machine, so that the packing can be easily performed when the washing machine is transferred.
