Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine in which two independent washing tubs are provided in a single outer frame and can be separately washed at the same time.

[0002]

2. Description of the Related Art In recent years, the number of housewives working part-time has increased, and the demand for shortening the time for housework and saving labor has increased significantly. Of the domestic labor, the above-mentioned demands are strong because the laundry work is particularly labor intensive, and recently, the fully automatic washing machines have become popular. Since the fully automatic washing machine is used as both a washing tub and a dehydrating tub, it is necessary to wash together the items that should be washed separately according to the type of clothes, colored and white items, and the degree of dirt. As a result, white goods may be dyed or delicate clothing may be damaged. To avoid this, you have to wash several times,
Even if you use a fully automatic washing machine, the result is time-consuming and time-consuming.

In order to solve the above problem, a washing machine in which a fully automatic washing machine and a semi-automatic washing machine are installed in parallel has been proposed (Japanese Patent Publication No. 63-66232). A schematic plan view of this type of washing machine is shown in FIG. Referring to FIG. 4, this washing machine S is a fully automatic washing machine S in which a washing tub and a dehydrating tub are combined.
1 and the semi-automatic washing machine S2 are arranged side by side in the same casing C. The plane dimensions of the washing machines S1 and S2 are
The depth d and width w1 of the fully automatic washing machine S1 are substantially the same as the depth d and the width w2 of the semi-automatic washing machine S2. For this reason, the size of the washing machine S, in particular, the overall width, is significantly increased. This does not fit into the reality of a small Japanese domestic washing machine. As a countermeasure against this, for example, as shown in FIG. 5, it is conceivable to reduce the width w2 of the semi-automatic washing machine S2 so as to have a vertically long shape to suppress the entire width of the washing machine. However, if the dimensions of the depth and width of the washing tub are unbalanced, the flow of water in the washing tub will deteriorate, and if there is a small amount of laundry there will be no problem. The inconvenience of not being able to wash easily occurs.

In order to solve these problems, a semi-automatic washing machine S2 of the two washing machines S1 and S2 is devised in shape to provide a washing machine in which the overall width is kept within a certain limit (Japanese Patent Laid-Open No. Hei 3). -215287). This washing machine is shown in Figure 6.
And shown in FIG. FIG. 6 is a schematic plan view showing the arrangement of the fully automatic washing machine S1 and the semi-automatic washing machine S2. Further, FIG. 7 is a front sectional view showing a schematic configuration of this washing machine.
Referring to FIG. 6 and FIG. 7, this washing machine is
A fully automatic washing tub 2 and a semi-automatic washing tub 3 are housed in an outer frame 1, and a pulsator 2 is provided at the bottom of the fully automatic washing tub 2.
The semi-automatic washing tub 3 has a pulsator 3a at the bottom thereof.

As shown in FIG. 6, the semi-automatic washing tub 3 has a narrow width w2 to suppress the entire width of the washing machine and a depth d.
2 is made substantially equal to the width w2 to ensure a good water flow in the tank.

[0006]

However, if the semi-automatic washing tub 3 is arranged as shown in FIG. 6, the space cannot be effectively used even if the washing machine has a large depth, that is, The shaded area in FIG. 6 exists as a dead space. This is too space-efficient and does not fit into the reality of a small Japanese family. Moreover, the volume of the semi-automatic washing tub 3 is extremely reduced, and the rated capacity is extremely reduced. Therefore, when washing separately
Since the capacity of the semi-automatic washing tub 3 is extremely small, there is a problem that it has to be repeatedly washed in multiple times.

[0007] Explaining these problems in consideration of the dimensions when a washing machine is actually installed in a house, the dimensions of a washing pan currently installed in a house are as follows: frontage width 800 mm, depth 640 mm, height 80 mm. Is common. The dimensions of the fully automatic washing tub 2 need to be substantially the same in width and depth because the washing tub 2 is circular. Therefore, fully automatic washing tub 2
Considering mainly the side, the size of the fully automatic washing tub 2 side is 64
It is preferably 0 mm square. As a result, the remaining dimension of the width of the above-mentioned washing pan is 160 mm, and the semi-automatic washing tub 3
The allowable size on the side is 160 mm in width and 640 mm in depth. However, for the above-mentioned reason, the size of the semi-automatic washing tub 3 side is inevitably made to be a 160 mm square in accordance with the smaller size. In this case, there is a dead space of 160 mm × 480 mm on the semi-automatic washing tub 3 side of the washing machine. Moreover, if the space of 160 mm square is available on the side of the semi-automatic washing tub 3, it will be too small compared to the side of the fully automatic washing tub 2 and it may be necessary to do separate washing even if doing separate washing. There is also. On the contrary, considering the size mainly on the semi-automatic washing tub 3 side, the size on the fully automatic washing tub 2 side is 160 mm square, which means that the capacity of the fully automatic washing tub 2 is too small and the dehydration work is divided many times. There is a problem that it has to be done.

[0008] Further, those that are extremely dirty (oil stains, etc.)
When washing separately, it is convenient to wash with warm water because the washing power improves, which is convenient, but there is also the problem that special warm water has to be prepared, which takes a lot of time and effort. Therefore, an object of the present invention is to provide a compact washing machine in which the entire width of the washing machine is suppressed and which can be separately washed, in which the space efficiency in the washing machine is improved to secure a large washing capacity and the washing power is enhanced. Is to provide a machine.

[0011]

According to the washing machine of the first aspect, since the pulsator of the semi-automatic washing tub is arranged on the side wall of the washing tub, it is not necessary to shorten the depth D _{0 of the} washing tub according to the width W _0. . In a semi-automatic washing tub with a pulsator on the side wall, a vortex is generated in the lateral direction to wash the laundry. When a vortex is generated in the lateral direction, the depth D ₀ and effective height H of the semi-automatic washing tub
_{If 0} is substantially equal, the lateral vortex can well rotate in the entire tub, so that the laundry is well agitated. As a result, the laundry is easily soiled and the depth dimension of the washing machine can be effectively used.

Further, according to the washing machine of the second aspect, since the convex portion is provided on the opposite wall of the pulsator on the side wall provided with the semi-automatic washing tub, the laundry is rubbed against the convex portion during washing. , It is easier for the laundry to get dirty. Further, according to the washing machine of the third aspect, since the washing tub of the semi-automatic washing section is of the drum type, the width dimension of the washing tub can be reduced and the depth dimension can be effectively used. .

Further, since the heater is disposed between the drum type washing tub and the outer washing tub for accommodating the washing tub, it is possible to warm the water in the washing tub of the semi-automatic washing section and perform washing with warm water. , The laundry becomes easier to get dirty.
