JPH10113493A - Decompression washing machine or decompression drier for laundry - Google Patents

Abstract

PROBLEM TO BE SOLVED: To wash clothing without damaging fabric and to dry the said clothing without transferring or lingering over the drying. SOLUTION: Laundry is put in a closed air tight container, incorporated with water and detergent, heated by a heater and decompressed by a vacuum pump. The water in the container boils at a low temperature. The force of the boiling bubble washes the laundry, and the fabric is not damaged. Then, combinations of discharging and pouring water, and, discharging, pouring water, heating and decompression rinse off the laundry. That is, discharging, pouring and discharging water is one pattern of rinsing and pouring water, heating and decompressing is the another pattern of rinsing to rinse off by the force of boiling bubbles so boiled at a comparatively low temperature. After the rinsing, discharging water, heating and decompression is given, water in the laundry is vaporized and then discharged and the clothing are dried.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a new washing machine or a washing and drying machine for washing clothes and the like, dishes and the like, and others.

[Conventional mode] Most conventional washing machines are of the stirring type, and most of the dryers are of the hot air type.

[What the present invention brings] By washing clothes with the washing and drying machine of the present invention, the clothes can be dried as they are without damaging the fabric and after washing.

[How the washing and drying machine of the present invention works] It is recommended that laundry be folded and stacked. If necessary
A light pressure plate may be placed on the finished laundry.
(Thus, after they have been washed and dried, the laundry remains folded and is less likely to wrinkle). Add detergent. Close the door and seal the container. Inject water. Heat. (Heating may be by a heater, by passing an alternating current through the washing liquid using an electrode, by applying a microwave, or otherwise).
The inside of the container is depressurized moderately with a vacuum pump. The reduced pressure is determined from the capacity of the vacuum pump and the temperature suitable for washing. At that temperature (eg, 60 degrees), the detergent added water begins to boil. The laundry is washed with the force of the boiling foam.
(Thus, do not damage the fabric). Meanwhile, the vacuum pump continues to work to maintain that state. After washing,
Turn off the heater and vacuum pump and drain. (If the vacuum pump is turned off, if the vacuum pump is of a type that does not allow air to naturally enter the container through the vacuum pump,
Provide a vent with a valve and open the vent when draining).
After draining, the next step is rinsing. Repeat water injection and drainage an appropriate number of times. Thereafter, it is poured, heated, depressurized, boiled and rinsed. And drain. The rinsing is repeated an appropriate number of times. Next is drying. After draining, heat and reduce the pressure. (Heating can be done in any of the ways described above, except that the clothing is not burned.) Thereby,
The moisture on the clothes evaporates and is exhausted and dried.
(The above can be applied to dishwashers, etc.).

[Embodiment of the Invention] "Claims"
And "How the washer-dryer of the present invention works". The following should be added. The exhaust hose should be connected to the drain. Because the exhausted steam is cooler than usual,
Most of them liquefy in water. When an alternating current is applied to the water and the clothing to heat the electrode, it is preferable to use an electrode that is as large as possible and does not dissolve in water. Alternatively, a number of protrusions may be provided on the electrode to ensure contact with clothing.

[Effects of the Invention] By washing clothes with the washing and drying machine of the present invention, the clothes can be washed without damaging the fabric, and when the washing is completed, the clothes can be dried as they are, thus requiring less labor.

Claims (1)

[Claims] 1. An airtight container having a door that can withstand the required decompression inside and that can be opened and closed, has a drain port and a valve at the bottom of the container, and has an exhaust port at the top of the container. If the vacuum pump is connected to the exhaust port, and the vacuum pump is stopped, if the vacuum pump is of a type that does not allow air to naturally enter the container through the vacuum pump, a vent with a valve is provided for drainage. A washing machine or a washing / drying machine having a mechanism capable of supplying water into the container, having a heating device inside or outside the container, and having a necessary control device, Is a combination of water injection, drainage, heating and decompression.
