Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a washing machine that washes laundry using foam.

Conventional Structures and Problems There are generally known washing methods such as a whirlpool type, an agitation type, and a drum type. However, both methods basically apply mechanical force to the laundry using a water system, which works together with the chemical action of the detergent to remove stains.Due to the mechanical force, fabric damage occurs to varying degrees. It was easy to occur. In order to eliminate this damage to the fabric, the detergent solution is circulated in the washing tub using a pump, creating a water flow in the washing solution in the tub, and the force of this water flow and the washing solution itself spouted from the pump are used to wash the laundry. Products that remove dirt have been proposed. However, this method has poor cleaning efficiency and is currently not in practical use.

Purpose of the Invention The washing machine of the present invention eliminates the above-mentioned conventional problems, and washes the laundry by bringing detergent foam into contact with or passing through it, and sprays water in a shower-like manner during rinsing. This improves cleaning efficiency and enables clean rinsing at the same time.

Structure of the Invention The washing machine of the present invention includes a washing tub for storing laundry, a detergent foam generating means for supplying detergent foam to the washing tub, a drainage pipe having pulp provided at the bottom of the washing tub, and a washing machine for washing laundry. It is equipped with a rinsing water supply device installed at the top of the tank that sprays water in a shower-like manner, and the detergent foam is used for washing and the water sprayed in a shower-like manner is used for rinsing.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is a wash basin for storing laundry 2;
is a storage section for storing detergent liquid, and has a drainage vibro installed at the bottom via a valve 4, and a pressurized pipe 7 connected to a blower 6 for generating pressurized air. The reservoir 3, the blower 6, and the pressure pipe 7 constitute a detergent foam generating means 8 that generates detergent foam from the detergent liquid. On the other hand, at the top of the washing tub 1 there is a bubble 1 no. 1 for guiding the detergent foam out of the washing tub 1.
An outlet pipe 6 is provided, and this suds discharge pipe 9 is connected to a discharge hose 10 leading to the outside of the washing machine.

Also, inside the washing tub 1, there are porous bodies 11 in the -L side part and the lower part, respectively.
．． 12 are arranged, and the laundry 2 is accommodated between the porous bodies 11 and 12. 13 is washing tub 1
A rinsing water supply device is provided on the upper lid 14 and sprays water in the form of a shower. It consists of a water supply device 18 to which a water supply port 17 is connected.

19 is a washing machine frame, and 20 is a leg.

Next, the operation of the above configuration will be explained.

First, the detergent liquid 21 is put into the reservoir 3 and air is forced through the pressure feed pipe 7 from the bottom of the washing tub to generate detergent foam 22, and this detergent foam 22 comes into contact with or passes through the laundry 2. It has a mechanism that allows it to be cleaned. That is, the laundry foam binds and carries away the dirt in the laundry. If the bubbles break while the laundry is passing through, a highly concentrated detergent solution will soak into the clothes, which can also make it easier to remove stains. In this way, cleaning becomes possible. And the detergent foam i2 that came into contact with or passed through this laundry
The foam passes through the porous body 11 at the top of the washing tub and is discharged to the outside from the foam discharge pipe 9. The porous body 11 in the upper part is provided to prevent the laundry 2 from being swept away by the detergent foam 22.

Note that the detergent foam that has once come into contact with or passed through the laundry is discharged to the outside, but it is liquefied by a defoaming device (not shown) in the foam discharge pipe 9, and is guided to the storage section 3 to be used again as detergent foam. It may also be used as

Next is rinsing, but as shown in Figure 2, after washing,
The water is then rinsed by wiping water from the rinsing water supply device I3 in a shower-like manner. That is, by sprinkling water on the laundry 2, the detergent adhering to the laundry 2 is flushed out through the drain pipe 10 by opening the pulp 4. Therefore, the detergent washed out from the laundry 21 is discharged as is, which is efficient.

Also, most of the bacteria that have landed on the laundry 3 are washed away during rinsing.

Note that even if a washing machine uses a dehydration rinsing method in which only washing is performed and rinsing is performed in a dehydrator attached to the washing machine, spraying water in a shower pattern is effective for cleaning the washing tub 11. It is.

Effects of the Invention As described in 2., since the present invention uses detergent foam to clean the cloth, there is no damage to the cloth, efficient cleaning is possible, and clean rinsing can be performed using water supplied in a shower-like manner. It is something. The water supplied in the form of a shower is also effective for cleaning the washing tub.
