DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described configuration, a sound generated from drive-related components such as the motor 7 and the transmission mechanism portion 6 during washing or dehydration, a sound generated due to vibration of the washing tub 4, and the like The internal sound of the main body 1 propagates to the outside of the main body 1 through the gap between the opening 1 ′ at the bottom of the main body 1 and the foot 12, that is, between the bottom of the main body and the installation surface 14 and significantly increases the noise level. Had. Therefore, as a means for solving this, it is conceivable that the opening 1 ′ of the main body 1 is simply sound-insulated by a plate to reduce the noise level. However, in this structure, the washing tub 4 overflows with washing water or the like. In this case, since it is difficult for the overflow to escape to the outside of the main body 1, there is a possibility that the electric parts such as the motor 7 attached to the bottom of the washing tub 4 may be exposed to the overflow, resulting in a safety problem. As described above, when the washing machine is transported, since the laundry receiving tub 4 is fixed to the packing material by using the transfer fitting 13, there is a problem that the opening cannot be eliminated.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a dehydration washing machine that lowers the noise level during washing and removal, and does not adversely affect the safety and the packability.

Means for Solving the Problems In order to achieve this object, the dehydration washing machine of the present invention is provided with a washing tub suspended and supported by a vibration isolation mechanism in the main body, and a washing / dehydrating tub and a stirring blade are provided in the washing tub. A motor for driving the washing / dehydrating tub and the stirring blade is provided inside the main body, and a bottom plate is attached to the bottom of the main body so as to close the opening, and the bottom plate forms a protrusion protruding to the vicinity of the installation surface of the main body. A communication hole that communicates with the outside is provided in a part of the portion of the protrusion that faces the installation surface, and a flat surface portion that faces the installation surface is formed around the entire circumference of the communication hole.

Operation With this configuration, the sound generated from the drive parts such as the motor during washing or dehydration, the sound generated from the vibration of the washing tub, and the like generated inside the main body are mostly insulated by the bottom plate attached to the bottom of the main body. Further, with respect to the sound overflowing from the communication hole of the projecting portion to the bottom portion, the sound can be sufficiently insulated because the gap between the projecting portion and the installation surface is small, and as a result, the noise level can be remarkably reduced. Further, even if washing water or the like overflows from the washing tub, drainage can be performed from the communication hole provided in the bottom plate, so that electric parts inside the main body will not be wetted. Further, the bottom plate is provided with a communication hole, which can be used to fix the washing tub during transportation, which does not adversely affect the packing property.

Example An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of a dewatering washing machine according to an embodiment of the present invention, and FIG. 2 is a perspective view of essential parts of the dewatering washing machine. In the figure, 1 to 14 are the same as the members of the conventional example shown in FIG. 3, and therefore their detailed description is omitted. Reference numeral 15 denotes a bottom plate attached to the bottom of the main body 1 with screws or the like, which is attached with the opening 1'at the bottom of the main body 1 closed to insulate sound. Reference numeral 16 denotes a protrusion that is bulged in the center of the bottom plate 15.
The tip of 16 projects to the vicinity of the installation surface 14 of the main body 1. 17
Is a communication hole provided in the center of the bottom surface of the protruding portion 16,
It is opened to a size that allows packing materials for fixing 13 to pass through.

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

As for the washing and dehydrating operations, the rotation of the motor 7 is transmitted to the stirring blade 5 or the washing / dehydrating tub 2 similarly to the conventional example.
To communicate through. At this time, the internal sound of the main body 1 such as the sound generated from the drive parts such as the motor 7 and the transmission mechanism 6 and the sound generated from the vibration of the washing tub 4 causes the opening 1 ′ at the bottom of the main body 1 and the foot 12. Although air is propagated to the outside through the gap between the two, the present embodiment lowers the noise level because most of the internal sound is blocked by the bottom portion 15 provided at the bottom portion of the main body 1. be able to. Further, some internal sound overflows from the communication hole 17 provided in the bottom plate 15, but since the projecting portion 16 projects to the vicinity of the installation surface 14, this overflow sound also has a narrow clearance between the projecting portion 16 and the installation surface 14. You can insulate sound. Further, even if the washing water overflows from the washing tub 4, it can be discharged to the outside through the communication hole 17 provided at the bottom, so that the overflowing washing water is collected at the bottom of the main body 1 to wet the electric parts such as the motor 7. Never. Also, the laundry receiving tub 4 may be fixed so as not to hit the main body 1 or the like during transportation, or the packing 13 can be fixed to the transfer fitting 13 through the communication hole 17 as in the conventional case.

In the present embodiment, the size of the communication hole 17 is the size through which the packing material for fixing the transfer fitting 13 passes, that is, the same size as the transfer fitting 13, but if the laundry receiving tub 4 can be fixed during packing, The small communication hole 17 may be used. Also the bottom plate 15
The shape of is not limited to that of the embodiment, and an appropriate shape can be used.

EFFECTS OF THE INVENTION As described above, according to the present invention, a laundry receiving tub suspended and supported by a vibration isolation mechanism is provided in the main body of a dewatering washing machine, and the washing receiving tub has a washing / dehydrating tub and a stirring blade. And a motor for driving the stirring blade is provided in the main body, and a bottom plate is attached to the bottom of the main body so as to close the opening, and the bottom plate forms a protrusion protruding to the vicinity of the installation surface of the main body. By forming a communication hole that communicates with the outside in a part of the part that faces the outside and forming a flat part that faces the installation surface around the entire circumference of the communication hole, it is generated from driving parts such as a motor during washing and dehydration Since the sound inside the main body such as the sound generated by the washing tank and the sound generated by the vibration of the washing tub is shut off, the noise level can be remarkably reduced. Further, even if washing water or the like overflows from the washing tub, drainage can be performed, so that the safety is high and the bottom of the main body has a communication hole, so that the washing tub can be fixed during transportation by almost conventional packaging. Moreover, the number of parts required for the configuration is small, the cost is low, the mass productivity is good, and the practical effects are great.
