[Structure] A structure is provided in which a drainage port 28 for rinsing water is provided above the washing tub 6, a water supply port 21 is opened below the washing machine 6, and a water supply hose 25 is connected to the water supply port 21 so as to communicate therewith.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for mounting a water inlet of a washing machine for enhancing the effect of rinsing.

[0002]

[Prior Art]

 In conventional washing machines, both the water supply port and the rinsing drainage port are provided around the upper part of the washing tub.When rinsing, water is supplied from above into the washing tub, and the water that reaches the drainage port above the washing tub is It was drained to the outside one by one.

[0003]

[Problems to be solved by the device]

 In the conventional rinse water supply / drainage structure described above, most of the new water supplied is drained from the upper drain port while rotating around the upper part of the washing tub being rinsed, and relatively to the lower part of the washing tub. It rotates and rinses with dirty water left behind. For this reason, in rinsing, new water is drained, and old water is used for rinsing. Therefore, rinsing requires a long time and requires a large amount of water and electric power.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a drainage port 28 for rinsing water above the washing tub 6, and a water supply port 21 opened below the washing tub 6 for supplying a water supply hose to the water supply port 21. The feature is that 25 are connected so that they can communicate with each other.

[0005]

[Action] The tap water that has passed through the water supply hose 25 is supplied to the inside of the washing tub 6 from the lower portion of the washing tub 6 through the water supply port 28 opened below the washing tub 6, so that all new water is washed. It works effectively as rinsing water while flowing upward from the bottom of 6. When the supplied water reaches the drainage port 28 provided above the washing tub 6 after rinsing, it is sequentially drained to the outside from the drainage port 28 in the upper part. For this reason, old dirty water will be drained first in the washing tub, and the entire water will be cleaned sooner.

【Example】

 In the following, the embodiment shown in the drawings will be described in detail. A washing machine main body 1 of a hollow box body made of a plastic material is placed on a leg 2, and a hollow box-shaped washing machine is provided at a substantially center of an upper wall 3 of the washing machine body. The tank 6 is accommodated and installed. A turntable 11 having a radial protrusion on its surface is rotatably supported in the center of the inside of the bottom wall 8 of the washing tub, and a pulley 12 is rotatably supported at one end of a shaft 5 penetrating to the outside of the washing tub. The pulley 12 is interlocked with a pulley 13 and a transmission belt 14, and the pulley 13 is attached to a drive shaft 10 of a motor 16 provided in the washing machine body 1. A plurality of wires 18 are connected to the motor 16, and the other end of each wire is connected to a plurality of operating instruments 19 installed on the rear end side of the upper wall 3 of the washing machine body.

A water supply port 21 is opened on the peripheral side of the bottom wall 8 of the washing tub, and the water supply port 21 is composed of a collar ring 22. The lower end of the water supply pipe 23 is connected to the end of the collar ring 22 which projects to the outer surface of the washing tub. The upper end of the water supply pipe 23 penetrates and projects toward the rear side of the upper wall 3 of the washing machine body, and the water supply hose 25 is detachably attached to the protruding portion 23a. The other end of the water supply hose 25 is attached to a water tap (not shown), and tap water flowing out from the water tap is supplied to the washing tub 6 through the water supply hose 25 and the water supply pipe 23 from the water supply port 21. Since this new water flows from the lower part of the washing tub 6 while rotating upward, it acts as effective rinse water.

On the upper end of the laundry tub peripheral wall 7, a plurality of narrow horizontally elongated holes are provided in parallel as upper drainage ports 28 for draining dirty water during rinsing. A drainage head 29 is projectingly provided on the outer surface of the peripheral wall of the washing tub so as to cover the plurality of horizontally long holes, a hole is bored at the bottom of the drainage head 29, and a collar ring 32 is inserted into the hole. A drain pipe 33 is attached to the tip of the color ring 32 protruding to the outer surface of the bottom of the drain head. The dirty rinsing water that has risen to the upper drainage port 28 sequentially flows out of the washing tub through the narrow horizontally elongated hole and is drained from the drainage head 29 through the drainage pipe 33.

A collar ring 36 is fitted around the periphery of the bottom wall 8 of the washing tub as a bottom drainage port 35 for draining all the water in the washing tub at the end of rinsing, and a tip of the color ring 36 protruding to the outer surface of the washing tub. A drainage pipe 37 is fitted in. A valve 37a is attached to the drain pipe 37, and the valve mechanism is connected to an operating tool 19 for opening and closing installed on the upper wall 3 of the washing machine body. The valve 37a is closed during rinsing so as to prevent the rinsing water in the washing tub from flowing out from the bottom drainage port 35, and is opened to drain the water in the washing tub after the rinsing. The device 19 can be opened and closed. The drainage pipes 33 and 37 attached to the upper drainage outlet 28 and the bottom drainage outlet 35 are connected by a Y-type connecting pipe 40 to form a single drainage pipe 41, which is a drainage pipe 41 of the washing machine main body peripheral wall 4. The hole formed at the lower end is connected to the drain hose 43 via the collar ring 41a.

The same structure is applied to a two-tub type washing machine that can also be rinsed in the dehydration tub. The present invention is not limited to this embodiment. For example, the water supply pipe 23 may be attached to the washing tub 6 at the lower end of the peripheral wall 7 of the washing tub, and the shapes of the water supply port 21 and the upper drainage port 28 may be changed. The structure is also arbitrary.

[0011]

[Effect of the device]

 Since the present invention is configured as described above, the new water that has passed through the water supply hose at the time of rinsing is supplied to the inside of the washing tub from the water supply port opened at the bottom of the washing tub and flows upward from the bottom while rinsing. As a result, the water that has reached the drain port opened above the washing tub is sequentially drained from the drain port. For this reason, relatively dirty old water is drained first, so that the rinse water in the washing tub can be cleaned earlier, and the effect of rinsing is better than that of the conventional washing machine that supplies rinse water from above. It will be extremely improved. As a result, the rinsing time can be shortened, which leads to the reduction of working hours and effective saving of rinsing water and power consumption.
