Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applied during the use of washing machines. It concerns noise reduction.

Conventional technology In recent years, as society has become more concerned about noise problems,
2. Description of the Related Art Reducing the noise level of home appliances with motors, such as washing machines, is attracting attention.

Conventional washing machines do not have a lid on the bottom of the main unit, and are still
Since the legs had gaps, the inside and outside of the main body communicated over a large area.

Problems to be Solved by the Invention However, with the above conventional configuration, the noise generated by the motor and other drive-related parts during washing and dehydration is
This has the disadvantage that the noise propagates to the outside of the main body through the gap between the bottom of the main body and the legs, significantly increasing the noise level. In addition, as a means to solve this problem, in a structure that simply fixes the bottom plate to the bottom of the main unit and insulates the sound inside the main unit, if an abnormal situation such as flooding occurs where water flows into the main unit, water will leak to the bottom of the main unit. This had the disadvantage that various electrical parts inside the main body were soaked in water, causing poor insulation.

The present invention solves the above-mentioned conventional problems.It reduces the scratching sound level during washing and dehydration, and even if an abnormal situation such as overflow occurs where water flows into the main body, the electrical components inside the main body can be The purpose of the present invention is to provide a washing machine that does not cause insulation defects.

Means for Solving the Problems In order to achieve this object, the washing machine of the present invention has an additional bottom plate that closes when a load greater than its own weight is applied to the bottom of the main body.

Function: With this configuration, the sound generated by the motor and other shaft-related parts during washing and dehydration is insulated by the bottom plate provided at the bottom of the main body, resulting in a significant reduction in the noise level. Furthermore, if an abnormal situation occurs in which water flows into the main body due to flooding, etc., the bottom plate is pushed open by the weight of the water, so that the water flowing into the main body is drained without accumulating.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, 1 is a main body, and 2 is a support added to the main body 1. 3 is an outer tank, which is suspended from the support part 2 by a suspension 4 having a spring and a damper. 5 is an inner tank, which doubles as a washing tank and a dehydration tank. 6 is a stirring blade provided at the center bottom of the inner tank 5, 7 is a transmission mechanism unit that transmits rotational force to the stirring blade 6 and the inner tank 5, and a reduction gear for washing and a switching clutch for washing and dewatering are installed inside. ing. Reference numeral 8 denotes a motor that applies rotational force to the transmission mechanism section 7. Reference numeral 9 denotes a transfer metal fitting, which is provided at the bottom of the outer tank 3.

Reference numeral 1o denotes a bottom plate, and a magnet 11 is provided on the upper surface of the outer periphery, and the bottom plate 1o is attached to the bottom of the main body 1 from below by a magnetic force of 8 degrees to prevent it from falling under its own weight.

Further, a concave water storage portion 12 is provided on the bottom plate 1o.

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

For washing, put the laundry and washing water into the inner tub 6, and transfer it to the transmission mechanism section 7.
This is done by setting the switching clutch to the washing side and transmitting the rotation of the motor 8 to the stirring blades 6. Next, dewatering is performed by setting the switching clutch of the transmission mechanism section 7 to the dewatering side and transmitting the rotation of the motor 8 to the inner tank 5. During the above-mentioned washing and dehydration, the motor 8, the transmission mechanism 7, etc. generate noise due to the drive, but in this embodiment, the bottom plate 10 is attached to the bottom of the main body 1, so that It insulates the sound generated from the outside, significantly lowering the noise level to the outside.

Next, when water overflows from the outer tank 3 due to a malfunction or the like and water flows into the main body 1, water accumulates in the water storage part 12 of the bottom plate 10, and the force generated downward on the bottom plate 1o due to the weight of the accumulated water is
When the magnetic force becomes stronger than the magnetic force of the magnet 11 that attaches the main body 1 and the bottom plate 10, the bottom plate 1° will fall from the main body 1, and the water flowing into the main body 1 will be drained from the gap created at the bottom of the main body 1. Water will not accumulate inside the main body 1.

As described above (according to this embodiment), since the bottom plate 1o is attached to the bottom of the main body 1 with an 8 degree magnetic force that will not fall under its own weight, the internal sound of the main body 1 is insulated and the noise level is significantly reduced. At the same time, water may overflow from the outer tank 3, etc.
If an abnormal situation occurs in which water flows inside the body 1, the bottom plate 10 will fall from the body 1, and by draining the water flowing into the body 1, each electrically connected component inside the body 1 will be exposed to water. This eliminates the possibility of insulation failure. moreover,
Since the main body 1 and the bottom plate 10 are attached by magnetic force, the bottom plate 1o can be easily attached and detached, and even if the bottom plate 10 falls while draining the water flowing into the main body 1, it can be easily returned to the initial state. be able to.

In addition, in order to prevent collision between the main body 1 and the outer tub 3 while the washing machine is being transferred, the upper part of the outer tub 3 is held on the inner surface of the inner tub 5 during packaging, and the lower part is held on the bottom of the transfer fitting 9. by doing,
Conventionally, the outer tank 3 has been fixed, but if the bottom plate 10 is easily attached and detached, the above conventional method can be used as is to solve problems during transportation. In other words, when packing for the first time in transport,
What is necessary is to remove the bottom plate 10 from the main body 1 and attach the bottom plate 10 to the main body 1 when installing the washing machine. Furthermore, by providing a concave water storage portion 12 on the bottom plate,
The bottom plate 1 in an abnormal situation where water flows into the main body 1.
In order to improve the detachability of the 0, improve the strength of the bottom plate 10, and eliminate chatter of the bottom plate 10, a thin bottom plate of 10K can be used, and costs can be reduced.

Next, FIG. 3 shows a second embodiment of the present invention.

In the figure, 13 is a pin provided at the bottom of the main body 1. 14 is a bottom plate, one end of which is hooked onto pin 13. A spring 16 has its central portion passed through the pin 13, and has one end pressed against the main body 1 and the other end against the bottom plate 14 to apply force in the direction of closing the bottom plate 14. A magnet 16 is attached to the upper surface of the bottom plate 14 on the opposite side from the pin 13. Reference numeral 17 denotes a water storage section, which is provided by forming a groove near the magnet 16 side of the bottom plate 14. Furthermore, the water storage portion 17 is provided with a small hole 18 .

With the above configuration, when an abnormal situation occurs in which water flows into the main body 1, some of the water flows out from the small hole 18, but most of the water flows into the water storage part 17, and the water is Due to the weight, the bottom plate 14 closes using the pin 13 as a fulcrum. This action causes the inflowing water to be drained away. Then, when this abnormal situation ends and there is no more water flowing in, the bottom plate 14 returns to its original state due to the action of the spring 16.

This allows the bottom plate 14 to be opened and closed automatically,
This will improve operability. Further, when the bottom plate 14 returns to its original state, the water remaining in the water storage part 17 is gradually drained out through the small holes 18, so that water does not accumulate in the bottom plate 14 and corrode the inside.

However, if the hole is of this size, the sound insulation properties will not be degraded.

In the first embodiment, the water storage section 12 is provided on the bottom plate 10, but various electrical components on the bottom of the main body 1 and the bottom plate 1
A flat bottom plate 1o without the water storage portion 12 may be used as long as there is a sufficient distance between the bottom plate 1o and the bottom plate 1o. Furthermore, in the first embodiment,
It is also possible to extend the bottom of the main body 1 from the surroundings so as to narrow the opening area of the bottom of the main body 1, thereby reducing the size of the bottom plate 10.
Included in the present invention. Furthermore, in the first embodiment, a material with adhesive force other than magnetic force may be used for the adhesive force between the main body 1 and the bottom plate 1o.

Incidentally, the above-mentioned contents can be similarly applied to the second embodiment. Further, in this embodiment, the adhesive force is applied by magnetic force and spring force, but if the spring force alone is properly adjusted, the same operation can be achieved.

Effects of the Invention As described above, the present invention has a bottom plate that is attached to the bottom of the main body with an adhesive force that is strong enough to prevent it from falling under its own weight, thereby insulating internal sound with the bottom plate, significantly reducing the noise level, and preventing water from overflowing. When an abnormal situation occurs in which water flows into the main body, the bottom plate comes off from the main body, drains the water flowing into the main body, and prevents insulation failure due to water soaking in various electrical parts inside the main body. is possible,
Furthermore, since the structure is simple as described above, it is possible to realize an excellent washing machine that can be manufactured at a very low cost.
