Next, the operation of the above configuration will be described. When laundry items such as clothes and detergent are placed in a washing/dehydration tank 1 and the washing machine is energized, water is automatically supplied, and then the rotor A2 rotates to agitate the laundry items. When the agitation continues for a certain period of time and ends, the washing water is drained after several rinsing steps, and the washing and dewatering tank 1 rotates to centrifugally dewater the laundry. The dehydrated water is discharged into the outer tank 3 through a small hole 1a provided in the washing and dehydrating tank 1, and led to the outside through a drain hose 14t.

Problems to be Solved by the Invention As washing machines that automatically perform a series of processes from washing to dehydration as described above have recently been used more often at night and early in the morning, reducing noise has become a major issue. ing. There are various factors contributing to the noise, such as the rotating vibration sound of the washing and dehydrating tank 1 during spin-drying, the rotating sound of the motor 10, the sound of water flowing during washing, the noise of the speed reducer 6, and the amount of opening and closing of various valves. It is necessary to effectively prevent these noises. Furthermore, such washing machines can be operated even when the user is not present, and for this reason, reliability and safety are important issues.

In particular, thorough measures must be taken to prevent water leakage.

However, in the washing machine having the configuration shown in FIG. 10, the lower end of the main body 5 of the washing machine remains open, and there are many problems with noise and water leakage.

The present invention solves these problems, and has the following objects: 1. To provide a washing machine that has a simple structure and can provide noise prevention effects and water leakage prevention effects.

Means for Solving the Problem In order to solve this problem, the present invention provides a washing and dehydrating tub having rotary blades inside the lower end, an outer tub that houses the washing and dehydrating tub, and a washing machine that encloses the outer tub. This washing machine includes a main body and a bottom plate that closes a lower opening of the washing machine main body.

With this configuration, the bottom opening of the washing machine body is closed by the bottom plate, which reduces noise during washing and spin-drying, and even if hot water is generated due to damage to the drain hose, the bottom plate catches it and prevents leakage. It is possible to provide a highly reliable and safe washing machine.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings (FIGS. 1 to 9). Note that the same reference numerals as in the conventional example refer to the same members, and detailed explanation thereof will be omitted.

First, the 15i! shown in FIGS. 1 and 2! To explain the embodiment, 21 is attached to the lower end of the washing machine main body 5 so as to be inclined downward in one direction.
The bottom plate 21 is closed at the lowest point, and a drain hole 23 is provided at the lowest point of the bottom plate 21 to be opened and closed by rotating a lever 22. Reference numeral 24 denotes a water leakage detector provided on the bottom plate 21J near the drainage hole 23. The water leakage detector 24 is configured to change its electrical resistance and generate a signal when it gets wet with water. This electrical signal is guided to the washing machine control circuit section (not shown) through the cape/L'25. 26 is Mtlf
These are installation legs provided at the four corners of the lower surface of the IB bottom plate 21.

In the above configuration, conventionally, much of the noise during washing and dehydration leaked out from the opening at the lower end of the washing machine main body 5, but in the above embodiment, the lower end of the washing machine main body 5 is sealed with the bottom plate 21, so the noise is reduced. leakage is prevented. Furthermore, even if water leaks due to damage to the drain hose 14, etc., this water will remain on the bottom plate 21 and will not leak onto the floor of the house. Further, this water collects at the lowest point of the bottom plate 21, and since a drainage hole 23 is provided there, it can be drained as appropriate by operating the lever 22. In addition, a water leakage detector 24 is installed near the drain hole, and a signal is generated when water leaks, so it is possible to know when it is time to drain water.

Furthermore, draining can be carried out automatically by providing a solenoid valve in the drain hole 23 and guiding leakage water with a hose.

According to the first embodiment described above, by sealing the lower end of the washing machine main body 5 with the bottom plate 21, noise can be reduced, water leakage can be prevented, and reliability can be improved. Furthermore, it is also possible to prevent foreign matter from entering from the lower end of the washing machine main body 5, resulting in improved safety.

Next, a second embodiment shown in FIG. 3 will be described.

Reference numeral 27 indicates an inspection opening floor formed on the back side of the washing machine main body 5 and a lower end opening 29 formed on the bottom of the washing machine main body 5.
t- A back plate/bottom plate integrally formed in a substantially L shape so as to be closed at the same time, and this back plate/bottom plate n is detachably fixed to the washing machine main body 5 using six screws 30 as shown in the figure. .

i2'j mentioned above! In this embodiment as well, since the lower end of the washing machine main body 5 is closed with the back plate/bottom plate 27, not only is noise leakage from the lower end prevented, but even if water leaks on the bottom plate 27, it is not only possible to prevent leakage of noise from the floor of the house, etc. leakage is prevented. In that case, by interposing a sealing material or the like between the bottom plate 27 and the washing machine main body 5, the effect of preventing noise and water leakage is further improved.

Further, by integrally forming the back plate and the bottom plate metal, it is possible to reduce costs.

Next, a third embodiment shown in FIGS. 4 to 7 will be described. A pair of guides are provided at the bottom of the 31-it washing machine main body 5, and a bottom plate 32 is inserted between the guides 31 to close the lower end opening of the washing machine main body 5.

Figure 7 shows the washing machine body 5 and the bottom plate 32' after removing the bottom plate 32 from the washing machine body 5! It shows a state in which it is stored and packed in a l-packing box 33. In FIG. 7, inside the packaging box 33, the top and bottom of the washing machine body 5 are cushioned and supported by packing material 16 made of Styrofoam, and the bottom plate 32 is placed between the outer surface of the washing tub body 5 and the inner surface of the packaging box 33. It is stored.

In this third embodiment as well, since the lower end of the washing machine main body 5 is closed with the bottom plate 32, not only is noise leakage from the lower end prevented, but even if water leaks on the bottom plate 32, it can be leaked to the floor of the house, etc. leakage is prevented. In that case, by interposing a sealing material or the like between the bottom plate 32 and the washing machine main body 5,
The effectiveness of preventing noise and water leakage is further improved.

Further, a fourth embodiment shown in FIG. 8 and FIG. 9 will be described. Reference numeral 34 denotes a bottom plate having installation legs 35 at the four corners of the lower surface and walls 36 rising from the four sides, which is fitted onto the outside of the lower end of the washing machine main body 5 and is fixed to the washing machine main body 5 with screws 37 from either side. 5 between the lower ends Ot- is designed to close. Even in such a washing machine, the washing machine main body 5 and the bottom plate 34 are packed and stored separately inside the packaging box section as shown in FIG.

When installing this washing machine on the floor, the bottom plate 34t
- Place on the floor, adjust the installation legs 35t so that they are horizontal, raise the bottom of the washing machine main body 5, raise the bottom plate 34, and fix them to each other.

In this fourth embodiment as well, since the entire lower end of the washing machine main body 5 is closed by the bottom plate 34, leakage of noise from the lower end is not only prevented, but even if water leaks on the bottom plate 34, it can reach the floor of the house, etc. leakage is prevented. In that case, by completely interposing the VA material between the bottom plate 34 and the washing machine main body 5, the effect of preventing noise and water leakage is further improved.

Effects of the Invention As described above, according to the present invention, the bottom plate metal membrane that closes the lower end opening of the washing gum body reduces noise during washing and dehydration, and also prevents water leakage due to damage to the drain hose, etc. However, the bottom plate can stop the receiver and prevent leakage, making it possible to provide a highly reliable and safe pumping machine.
