Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine installation stand.

[0002]

2. Description of the Related Art In a housing complex such as an apartment or a condominium, a washing machine and a dehydrator are installed indoors. Conventionally, the installation method has often been to place it directly on the floor surface or to put the legs of the washing machine on a concrete block placed on the floor surface, and drainage of the washing machine was installed on the floor surface. It was leading to the drain.

However, since water attached to the body of the washing machine may fall on the floor surface and wet the floor surface, floor pans (drain pans) for installing the washing machine have been often used in recent years. The floor pan for receiving the water has a rectangular tray shape, and metal, resin, concrete or the like is used as the material. Some are made of concrete and are molded integrally with the floor. In addition, the floor pan is provided with a drainage outlet for drainage.

[0004]

A washing machine and a dehydrator are provided with a rotary tub inside, and a motor rotates the rotary tub to perform washing and dehydration. And since laundry and water are contained in the rotary tub, vibration is likely to occur. Therefore, when a washing machine is installed on a rigid body such as a floor surface, a concrete block, or a conventional floor pan, the vibration of the washing machine is transmitted to the floor surface, and the vibration is transmitted as a vibration sound to the room below, causing an inconvenience to the residents below. I may call.

When the rotating tub of the washing machine is rotating at a constant speed, the vibration is relatively small, but when the rotation speed changes such as when the rotation is started or when the rotation is stopped, the washing machine is moved laterally. Twisting force is exerted, and horizontal vibration is likely to occur. In particular, recently, the number of washing machines that perform constant-speed rotation has decreased, and the mainstream is a type of washing machine that repeats a cycle of "rotation, stop, rotation" or "rotation, reversal" in a short cycle. Has become even more significant.

Therefore, there is a demand for a washing machine installation stand that absorbs vibrations of the washing machine and makes vibration noise less likely to occur.

[0007]

The washing machine installation stand of the present invention comprises a plurality of legs (5) at the bottom of the floor pan (1), and each leg (5) is connected to the floor pan (1). An upper rubber member (9) and a lower rubber member (11) connected to the floor surface (2), and at least one of the upper rubber member (9) and the lower rubber member (11) has a tubular portion (11a). ), A part (9a) of one of the rubber members (9) is fitted so as to be inscribed in the tubular portion (11a) of the other rubber member (11), and the upper rubber member (9) A spring (13) is arranged between the lower rubber member (11) and the lower rubber member (11).

[0008]

The vertical spring vibration can be absorbed by the coil spring, and the horizontal vibration can be absorbed by the adjacent rubber members coming into contact with each other and deforming. Therefore, it is possible to effectively suppress the vibration of the washing machine and prevent the vibration noise.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to preferred embodiments. FIG. 1 shows the overall shape of a washing machine installation stand of the present invention. In the figure, (1) is a resin floor pan installed on the floor surface (2), on which a washing machine (3) is placed. (4) is a drainage port provided in the floor pan (1), which is connected to the drainage port of the floor surface (2) by a flexible pipe (not shown). (5) is a leg portion provided on the bottom of the floor pan (1), and an enlarged cross-sectional view thereof is shown in FIG.

(6) is a core attached to the floor pan (1) by a nut (7). On the floor side surface of the floor pan (1), there are arranged an upper mounting member (8) having an edge portion and an upper rubber member (9) so as to fit inside thereof. Part of the upper rubber member has a cylindrical portion (9a) perpendicular to the floor pan (1). The core body (6) penetrates the upper mounting member (8) and the tubular portion (9a) of the upper rubber member (9), so that the core member (6), the upper mounting member (8), and the upper rubber member (9). ) And are fixed together.

Reference numeral (10) is a lower mounting member fixed to the floor (2) by a nut (12) and having an edge portion. A lower rubber member (11) is arranged inside the edge portion. Lower rubber member (1
1) has a tubular portion (11a) in a direction perpendicular to the floor surface (2), and its inner diameter is slightly larger than the outer diameter of the tubular portion (9a) of the upper rubber member (9).

The tubular portion (9a) of the upper rubber member (9) is fitted inside the tubular portion (11a) of the lower rubber member (11) so as to be inscribed. A coil spring (13) is arranged between the upper rubber member (9) and the lower rubber member (11). Therefore, a spring is interposed between the floor pan (1) and the floor surface (2).

As for the vibration in the vertical direction (direction perpendicular to the floor surface), the coil spring (13) flexes to absorb the vibration and suppress the vibration from being transmitted to the floor surface (2). .
In addition, for vibration in the lateral direction (direction parallel to the floor surface), the outer surface of the tubular portion (9a) of the upper rubber member (9) and the lower rubber member (1
The inner surface of the cylindrical portion (11a) of 1) comes into contact with each other and both elastic bodies are deformed to absorb vibrations and suppress the transmission of the vibrations to the floor surface (2).

In the above embodiment, the upper rubber member is inscribed in the tubular portion of the lower rubber member, but conversely, the lower rubber member is inscribed in the tubular portion of the upper rubber member. Good. The ends of the spring coil may be embedded in the rubber member. The spring is not limited to the coil spring, and an air spring or the like may be used. As for the installation item, a dehydrator or a clothes dryer having a rotating portion may be installed instead of or in addition to the washing machine. Moreover, the type of the washing machine is not limited, and it is needless to say that the washing machine may be a one-tub type or a two-tub type having a dehydration-dedicated tub.

[0015]

As described above, according to the present invention, it is possible to prevent the vibration when the washing machine is used from being transmitted to the floor surface, and it is possible to eliminate the vibration noise disturbance to the downstairs especially in the concentrated house.
