Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing machine equipped with a detergent dissolving container.

Generally, in a washing machine, the clothes to be washed and powdered detergent are placed in the water in the washing tank, and the detergent is dissolved in the water by the water flow generated by the pulsator, but if the detergent absorbs moisture and hardens, it will dissolve. It is difficult to clean, and there is a risk of clogging drain passages such as drain valves. In particular, natural detergents (so-called powdered soaps made from oils and fats) not only easily absorb moisture, but are also difficult to dissolve in water, forming particles that float in the water and can clog drainage channels or stick to clothing. be. Filling the washing tank with hot water makes it easier to dissolve the detergent, but it is uneconomical to prepare a large amount of hot water.

In this invention, an amount of detergent corresponding to a specified amount of water in a washing tank is poured into a container having an internal volume that can accommodate a sufficient amount of liquid to dissolve the detergent. By thoroughly dissolving the detergent solution in a large amount of water or warm water, and then adding the detergent solution to the water in the washing tank or the water supplied to the washing tank, the detergent can be well dissolved in the water in the washing tank and the detergent solution can be dissolved well in the water in the washing tank. This is an attempt to eliminate shortcomings.
In particular, a stirring blade is provided in the container to dissolve the detergent more quickly and completely, and
A drive source is provided in the container installation part of the washing machine where the container is detachably attached, so that when the container is attached to the installation part, the stirring blade is connected to the drive source, making handling of the container and dissolving detergent convenient. It is something to do.

Further, this invention provides a ceiling wall that covers at least a part of the top opening of the container in the container installation part on the side of the washing machine, and a stirring blade is suspended into the container from the ceiling wall,
Dissolving the detergent and handling the container can be made convenient without requiring a complicated structure in which the container is provided with stirring blades.

A detailed explanation will be given below with reference to the drawings. 1st
Figures 1 to 3 show an embodiment of the present invention. In the figure, 1 is a washing machine equipped with a washing tank 2 with an open top (see Fig. 4), and a control device equipped with a time switch etc. on the rear top. A box 3 is provided. Reference numeral 4 denotes a container for dissolving detergent, which is formed of a transparent or translucent material into a cylindrical shape with an open top and a handle 5 on the side.

The container 4 is equipped with a scale 7 on the side that indicates the amount of detergent required to obtain the appropriate detergent concentration for the specified amount of water in the washing tank 2, and the amount of liquid is sufficient to dissolve the indicated amount of detergent. (Indicated by scale 8 on the side of the container)
It has an internal volume that can accommodate. In the case of a two-tank washing machine with parallel dehydration tanks, the capacity for the clothes to be washed is approximately 2
The washing tank is filled with about 30 kg of water, and the appropriate concentration is about 90 c.c. of natural detergent for this 30 water. Since a natural detergent of 90 c.c. is sufficiently dissolved in warm water of about 30° C., the internal volume of the container 4 is set to 1, for example, and the detergent scale 7 is provided at a position of about 90 c.c.

In addition, when there are few clothes to be washed, there is a water volume scale (not shown) in the washing tank 2 according to the amount of clothes.

The washing machine 1 has an installation part 18 in a part of the control box 3 in the upper part of the washing tank 2, which is formed into a notch shape with the top and front surfaces open and allows the container 4 to be detachably attached thereto. The bottom of the installation part 18 has a recess 18 into which the bottom protrusion 4a of the container 4 is fitted.
A is provided. Further, a small motor 21 is provided below the installation part 18, and a drive-side joint 22 driven by the motor 21 is protruded from the recess 18a. The drive side joint 2 is provided at the lower end of the shaft 11.
It has a driven side joint 23 connected to 2. In addition, the container 4 has a heater 24 embedded in the bottom wall, and the heater 24
A plug 25 electrically connected to 4 is made to protrude downward. The recess 18a of the installation part 18 is connected to the plug 25.
It has an outlet 26 connected to. Note that water can be supplied to the washing tank by connecting a water supply hose 19 extending from a water faucet to a connection port 20 provided in the control box 3.

FIG. 3 shows an electric circuit, in which 27 is a plug connected to a power source, 28 is a bimetal that responds to the heat of the heater 24, and 29 is the bimetal 28.
This is a switch that is operated by a switch. When the push button 30 is pressed to close the switch 31 connected in series to one contact a of the switch 29 and the heater 24, the heater 24 is energized and the water in the container 4 is heated. Claw 33 operated by bimetal 28 at the same time
engages with the notch 30a to hold the push button 30 in the pressed state. When the heater 24 reaches a predetermined temperature, the switch 29 closes contact b due to the deformation of the bimetal 28.
The motor 21 is energized to stir the hot water in the container 4 and dissolve the detergent. When the thermistor 32 connected in series to the motor 21 is energized for a predetermined period of time, its resistance value increases due to self-heating, and the energization to the motor 21 is cut off to stop stirring. Further, when the switch 29 is switched to the aforementioned contact point b, the pawl 33 is removed from the notch 30a and the spring 34 returns the push button 30 to the protruding state, and the switch 31 is opened.

When the temperature of the heater 24 decreases and the bimetal 28 returns to normal, the switch 29 switches to contact a.
Since the switch 31 is already open, the heater 24 is not energized.

Although it is uneconomical to obtain hot water to fill the washing tank 2, it is easy to obtain a small amount of hot water to be poured into the container 4. For example, if the container 4 containing detergent and cold water is placed in the installation part 18 of the washing machine By operating the push button 30 in the attached state, the container 4
The detergent can be completely dissolved by changing the cold water inside to hot water, and the concentrated detergent solution can be poured into the spout 4 of the container 4.
By pouring the water from b into a large amount of water in the washing tank, you can obtain washing water that is completely dissolved and has an appropriate concentration. Of course, if you pour hot water into the container, the heater 24
At , the switch 29 is switched and the stirring operation is started without substantially energizing. Container 4 when not in use
If you attach it to the installation part 18 of the washing machine, you won't have to worry about where to put it. When adding detergent or water as necessary, the container 4 may be removed from the installation portion 18.
