Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a vibration suppressor for a home laundry in which a clothes dryer is combined with a washing machine.

[Conventional technology]

Such a home laundry is, as shown in FIG. 10 and FIG. 11, placed on a stand (2) on which a one-tank fully automatic washing machine (3) or a two-tank washing machine (4) is arranged as a washing machine below. A clothes dryer (1) is installed so that a washing machine and a clothes dryer can be combined and used in the same place.
After taking out the clothes that have undergone all the washing processes of rinsing and dehydration from the washing machine, put them inside the outer drum (1a) of the clothes dryer (1) above and inside the rotating drum that is the drying chamber. It is put in and dried.

By the way, during operation of the clothes dryer, the rotating drum rotates, and the impact of the clothes in the drum caused by the rotation causes the outer box (1
In a), a large amplitude sway is generated as shown in FIG. 13, and this sway is transmitted to the stand (2), and the clothes dryer (1) and the stand (2) are greatly swayed as shown in FIG. (2) might fall.

Therefore, in order to prevent falls, conventionally, for example, a washing machine (3)
For example, butyl rubber or the like is used as a vibration-proof rubber having good vibration damping property in (4) or the leg (5) of the stand (2), or the rigidity of the stand (2) is increased.

[Problems to be solved by the device]

However, the shaking of the home laundry is mostly due to the rigidity of the floor on which the clothes dryer is installed, so using vibration-proof rubber on the legs of the washing machine or stand, or simply increasing the rigidity of the stand will prevent shaking of the entire laundry. It was difficult to obtain a sufficient damping effect.

The object of the present invention is to eliminate the inconveniences of the conventional example, effectively dampen the vibration of the clothes dryer during operation, regardless of the rigidity of the installed floor, and reliably prevent the laundry from falling over. To provide a suppression device.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in a home laundry in which a clothes dryer is installed on a stand, liquid is enclosed in a casing in an outer box of the clothes dryer, and the vibration frequency of the clothes dryer is the same. The gist is that a liquid balancer having a liquid level frequency of 1 is attached.

[Action]

According to the present invention, since the liquid balancer having the liquid surface frequency matching the vibration frequency of the clothes dryer is provided on the upper surface of the outer box of the clothes dryer, the liquid balancer vibrates when the clothes dryer vibrates. It moves in the opposite phase to the shake of the dryer and attenuates the shake. Thereby, the vibration of the stand, that is, the home laundry is suppressed.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of an essential part showing an embodiment of a vibration suppressor for home laundry according to the present invention. As a basic structure of laundry, as shown in FIG. 2 and FIG. Clothes dryer (1) on a stand (2) where a one-tank fully automatic washing machine (3) and a two-tank washing machine (4) are arranged as
Is installed and the laundry is constructed by combining the washing machine and the clothes dryer (1) with the stand (2).

In such a home laundry, the liquid balancer (7) is installed, for example, on the upper surface of the outer box (1a) of the clothes dryer (1).

This liquid balancer (7) is, for example, one in which an appropriate amount of salt water (6) is enclosed in a closed rectangular parallelepiped casing (7a) as shown in FIG. 4 and FIG.
The liquid surface frequency in a) was made to match the vibration frequency of the clothes dryer (1).

When the casing (7a) is a rectangular container having a flat bottom and a width a and length b and a liquid having a depth h is contained in the rectangular container, the liquid surface frequency is calculated by the following equation.

In this case, m and n are positive integers of 0 and represent the mode of liquid vibration.

Therefore, the size of the container and the depth of the liquid may be set so that the liquid level vibration frequency fm ² , n matches the vibration frequency of the clothes dryer (1) measured in advance.

Next, usage and operation will be described.

For example, when clothes that have been dehydrated by the one-tank fully automatic washing machine (3) are put into the rotating drum in the clothes dryer (1) above and the clothes are dried, the rotating drum rotates to remove the clothes. The impact on the drum causes the clothes dryer (1) to vibrate, causing the stand (2) to shake as shown in FIG.

At this time, the liquid balancer (7) installed on the upper surface of the outer box (1a) of the clothes dryer (1) also shakes together with the clothes dryer (1), and salt water (6) in the casing (7a) As shown in FIG. 8, the liquid balancer (7) is shaken because the liquid level frequency of the liquid balancer (7) is set to be the same as the vibration frequency of the home laundry. It moves in the opposite phase and absorbs the shaking of home laundry and suppresses vibration.

In this way, even if the clothes dryer (1) vibrates, this vibration is absorbed by the liquid balancer (7) and the amplitude becomes small as shown in FIG. 9, so that the stand (2) shakes greatly. There is no.

[Effects of the Invention] As described above, the vibration suppressor for a home laundry of the present invention absorbs and damps the vibration of the clothes dryer during operation at the clothes dryer regardless of the rigidity of the installed floor. Since this is done, the vibration of the clothes dryer can be prevented from being transmitted to the stand so that the clothes shake greatly and fall.
