Description

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

Structures of Conventional Examples and Their Problems In general, known washing methods include a whirlpool type, an agitation type, and a drum type. However, both methods basically apply mechanical force to the laundry using a water system, and together with the chemical action of the detergent, remove dirt. The fabric was easily damaged. 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 force of the washing solution itself spouted from the pump are used. A product has been proposed that removes stains from laundry. 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.The washing machine washes the laundry by bringing detergent foam into contact with or passing through it, and when rinsing, sprays water in a shower over the entire clothes. To ensure rinsing of water, and to provide a simple and economical configuration of a water supply device for a shower.

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 drain pipe having a valve provided at the bottom of the washing tub, and a washing machine. A rinsing water supply device is provided at the top of the washing tub and sprays water in a shower shape, and a part of the upper lid covering the top of the washing tub has a downwardly curved protrusion. The structure has a shower nozzle formed in the part.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is a washing tub for storing laundry 2, 3 is a storage part for storing detergent liquid, and a drain pipe 5 is provided at the bottom via a valve 4, and a pressure feed pipe is connected to a blower 6 that generates pressurized air. It has 7. The reservoir 3, the blower 6, and the pressure feed pipe 7 constitute a detergent foam generating means 8 that generates detergent foam from the detergent liquid. On the other hand, a foam discharge pipe 9 is provided at the top of the washing tub 1 for guiding detergent foam out of the washing tub 1.
is connected to a discharge hose 10 that connects to the outside of the washing machine.

Further, porous bodies 11 and 12 are arranged in the upper and lower parts of the washing tub 1, respectively, and the laundry 2 is accommodated between the porous bodies 11 and 12. Reference numeral 13 denotes a rinsing water supply device provided on the upper lid 14 of the washing tub 1, which sprays water in a shower-like manner. It consists of a water supply tool 18 whose upper surface is covered and a water supply hose 17 is connected to it.
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.
It is designed so that it can be cleaned by coming into contact with or passing through it. That is, the detergent foam binds and carries away the dirt in the laundry. Furthermore, if the detergent foam breaks while passing through the laundry, a highly concentrated detergent solution will soak into the laundry, which can also make it easier to remove stains. In this way, cleaning becomes possible. The detergent foam 22 that has come into contact with or passed through the laundry 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 washed away by the detergent foam 22.

Next is rinsing, as shown in Figure 2, after washing,
The laundry 2 is rinsed by being showered with water from a rinsing water supply device 13. That is, by spraying the laundry 2 with water, the detergent adhering to the laundry 2 is flushed out through the drain pipe 10 by opening the valve 4. Therefore, the amount of washing washed out from the laundry 21 is discharged as is, which is efficient.

Also, most of the bacteria attached to the laundry 3 are washed away during rinsing.

Here, in this embodiment, the upper lid 1 of the washing tub 1 is
A number of holes 15 protrude by bending a part of 4 downward.
A protrusion 16 is formed to serve as a shower outlet. Therefore, it can be processed simultaneously when molding the upper lid 14, which is simple and economical.

Effects of the Invention As described above, since the present invention uses detergent foam to clean the clothes, there is no damage to the fabric, and efficient cleaning can be performed, and since the protrusion is curved, the rinsing water can be applied to the entire clothes. In addition, bubbles attached to the inner wall of the washing tub can be washed away, resulting in clean rinsing. Further, since the protrusion is formed in a part of the upper lid, the structure is simple and economical.
