Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing machine in which a washing tub with rotary blades arranged at the inner bottom is housed in an outer casing, and this outer casing is supported via a base and a support. The purpose of the present invention is to provide a structure in which the washing machine is shaped approximately like a wine glass and can create extra space compared to conventional washing machines of the same type.

In conventional washing machines of this type, all functional parts, such as the washing tub and the motor that is the drive source, are housed in a cubic-shaped outer casing, and if this washing machine is installed in the corner of a bathroom, for example, However, the corner was completely occupied by the washing machine.

On the other hand, washing machines currently have a large amount of space between the washing tub and the outer casing, below the washing tub, and the like. This tendency has become more pronounced with the recent increase in washing and dehydrating capacities.

The above-mentioned space does not have any special effect when compared with the original function of the washing machine.

The present invention reduces the installation space of the washing machine and creates more indoor space by eliminating space within the outer casing. The basic configuration of the present invention is that a washing tub with rotary blades arranged on the inner bottom is housed in an outer casing, and a support is provided between the bottom side of the outer casing and a base placed on the floor. It is connected by .

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is a washing tub, which in this embodiment has a structure that also serves as a dehydrator. Specifically, it has a large number of drain holes 2 on its peripheral wall, and a balancer 3 containing liquid inside is attached to the upper open end. Reference numeral 4 denotes a rotor blade arranged at the inner bottom of the washing tub 1.

Reference numeral 5 denotes an outer casing housing the washing tub 1, and a ring-shaped cover 6 is disposed at the upper opening, and the opening of the cover 6 can be opened and closed by a lid 7. 8 is an operation box provided at the rear of the upper surface of the outer housing 5, and the operation panel 8a has a knob 10 for adjusting the set pressure of the pressure switch 9, that is, for changing the water level.
and a knob 12 of a time switch 11.

Reference numeral 13 indicates a drain port provided on the bottom wall of the outer casing 5, and 14 indicates a water overflow port provided on the upper side wall of the outer casing 5. 15
The degree of compression of the air in the air trap 15 due to the rising water level in the outer casing 5 is transmitted to the pressure switch 9 via the air hose 16, and this compression When the air pressure reaches a predetermined value, as is well known, the contacts of the pressure switch 9 are switched to stop the operation of the electromagnetic water supply valve (not shown), water supply is stopped, and the drive source for the rotary blade 4 described above is activated. It is something.

17 is a drive device fixed to the lower surface of the bottom wall of the washing tub 1, which includes a motor and a clutch mechanism (none of which are shown).
etc. are built-in. During washing and rinsing, the rotational force of the motor is transmitted to the rotary blades 4 by the clutch mechanism, and the rotation of the rotary blades 4 agitates the clothes together with the washing water. Further, during spin-drying, the rotational force of the motor acts to rotate the washing tub 1 through the clutch mechanism. The above motor is
In order to reduce the dimension in the height direction, an axial gap induction motor, that is, a motor in which the gap between the rotor and the stator is formed in the length direction of the rotating shaft, is preferable, but the gap is formed in the radial direction. It may also be a general induction motor.

Reference numeral 18 denotes a drain valve installed at the drain port 13, which must be closed before washing and rinsing begins.
When washing and rinsing are completed, the washing tub 1 and the outer casing 5 are opened and water is discharged.

19 is a three-way pipe, one of which is connected to the drain port 13 through a hose 20, one of the remaining pipes is connected to the overflow port 14 through an overflow hose 21, and the other of the remaining pipes is connected to a drainage tube. It communicates with one end of the body 22.

Reference numeral 23 denotes a cover member which covers the drive device 17, the three-way pipe 19, etc. from below and has a peripheral portion fixed to the peripheral edge of the lower surface of the bottom wall of the outer casing 5 by screwing or the like, and has a substantially dish shape. Reference numeral 24 denotes a cylindrical support whose upper end is fixed by welding 25 or screws to the peripheral edge of the opening 23a provided in the approximate center of the cover member 23, and whose lower end is attached to a base placed on the floor 26. It is connected and fixed to the substantially central portion of the upper surface of the stand 27 by welding 28 or screwing. That is, the cover member 23 has sufficient strength to support the outer casing 5 and the various members attached thereto, and the support column 24 has sufficient strength to support all the members above the cover member 23. . Furthermore, the base 27 also has sufficient strength.

The base 27 has an inverted dish shape, and a plurality of legs 29 made of an elastic material such as rubber are provided at appropriate intervals on the periphery of the lower surface of the base 27. The spring 30 receives a load against the urging force of the spring 30, and at the same time receives viscous resistance due to contact between the spring 30 and its inner small diameter portion 27a, thereby exhibiting a buffering performance.

The drainage cylindrical body 22 described above is provided within the support column 24, the upper end communicates with the three-way pipe 19 as described above, and the lower end opens downward within the base 27.

31 is a drainage cover provided on the floor surface 26, and the hole 31
a, receives the water coming out from the lower end opening of the cylindrical body 22, and guides it to, for example, the sewer via the drain 32. Reference numeral 33 denotes a ring-shaped wall protruding from the floor surface 26 so as to surround the base 27, and prevents drainage water from spreading onto the floor surface.

In addition, a drainage cover 31 and a wall 33 are installed directly on the floor surface 26.
The base 27 may be placed on a tray having a drainage cover without providing such a drain cover.

34 is a constriction formed by the support 24 that connects the cover member 23 and the base 27;
This surrounding space 35 is donut-shaped and constitutes a mounting portion for a substantially horseshoe-shaped storage container 36. That is, the storage container 36 has a recess 36a in the radial direction that receives the support column 24, and by inserting the support support 24 into the recess 36a in the direction of arrow a, the storage container 36 is connected to the cover member 23 and the base 27.
It fits like a sandwich between the two, and can be removed by pulling in the direction of arrow b. 36b is a storage container 36
The insertion/removal handle 36c is a partition member for appropriately partitioning the inside of the storage container 36 as necessary.

Here, the above-mentioned time switch 11 is used for washing,
In order to automatically execute the rinsing and dewatering programs, the contacts are opened and closed by the rotation of the timer motor, and the loads on the water supply valve, drain valve 18, pressure switch 9, etc. that supply water to the washing tub 1 are controlled. do. Further, the constituent materials of the washing tub 1 and the outer casing 5 are preferably made of resin from the viewpoint of molding, but are not necessarily limited to this, and may be made of metal. In addition, since it is necessary to ensure the strength of the cover member 23, pillar 24, and base 27, it is preferable that they be made of metal, but they may also be made of resin by integrally molding reinforcing ribs as appropriate. Can be done.

Note that 37 is a safety switch that stops the power supply to the electric load and prevents the program from proceeding when the lid 7 is opened, and 38 is a power cord that is plugged into an outlet 40 provided on the wall 39 of the room. 41 is a lead wire connecting the load such as the motor and the time switch 11, and 42 is a water supply hose.

According to the above configuration, since the cover member 23 provided on the lower surface side of the outer casing 5 and the base 27 are connected by the support 24 forming the constricted part 34, the overall shape becomes approximately a wine glass shape, as shown in FIG. Even if it is installed in the corner of the room as shown in the figure, there is a space 3 around the pillar 24.
5, the washing machine does not occupy much space. On the contrary, it is possible to create a space 35, eliminate the image of conventional washing machines occupying space, and provide a washing machine that can be easily installed anywhere.

In addition, as shown in FIG. 2, the space 35 allows a storage container 36 to be installed in a removable manner, and inside the storage container 36 there are detergents, finishing agents, small laundry items such as scrubbers, and even handkerchiefs. , dirty socks, and other various items can be easily stored and taken out.

In this way, the space 35 eliminates the image of a conventional washing machine that it occupies space, and at the same time creates a storage space for articles.

In addition, since the cylinder 22 for drainage exists in the column 24 in a longitudinally long state, the water discharged from the outer casing 5 side quickly passes through the cylinder 22.
Therefore, drainage performance is good. Furthermore, the drive device 17, which has conventionally been disposed close to the bottom part within the outer casing.
is located above the support column 24, and the splash of drainage generated on the bottom side of the base 27 cannot reach the drive device 17, and a dangerous situation such as leakage of electrical load is extremely likely to occur. hard.

In addition, in this example, the case where the washing tub also serves as a spin-drying tank has been described, but even if a washing tub that does not have a spin-drying function is used, the same effect as this example can be achieved. Needless to say. In this case, the outer casing does not need to function as an outer tub of a single-tank dehydrating washing machine.
Drainage, overflow, etc. can all be done directly from the washing tank.

Furthermore, in this embodiment, a configuration is described that is equipped with a time switch that automatically performs washing, rinsing, and dehydration. It's okay.

As described above, according to the washing machine of the present invention, since a space can be created between the lower surface of the outer casing and the base placed on the floor, it is possible to create a space between the lower surface of the outer casing and the base placed on the floor. This eliminates the image that conventional washing machines have of occupying a large amount of space, and furthermore, because the space can be used to install a storage container, it is possible to eliminate the image that conventional washing machines have, which is that they occupy a large amount of space. This can greatly increase the utility value of the washing machine. In addition, by forming the drainage route inside the support column, space can be used more effectively than when the drainage hose is exposed outside.
To provide an easy-to-use washing machine that can prevent the drain hose from getting caught during work.
