Description

The present invention relates to a washing machine for washing clothes.

In the fully automatic washing machine, the types of detergents have increased in recent years, and the number of mechanisms provided with a pull-out detergent case at the top of the washing machine has increased so that the user can easily put the detergent or fabric softener into the washing machine. In this mechanism, it is a mainstream that powder detergent, liquid detergent, softener and each container are provided side by side to form a three-in-one configuration.

However, in order to satisfy the above requirements within a limited area due to the configuration of the fully automatic washing machine, the volume of each container is small, and it is generally a vertically long square configuration. Since each container has a small volume, there is a problem that different agents overflow into the containers adjacent to each other when the detergent is added.

In addition, when the detergent is dissolved, the water injection route is also limited, and it is difficult to completely dissolve all the scattered detergent at the time of water injection. When water is injected at a low flow rate, the water does not sufficiently hit, so the undissolved detergent remains. Trigger.

The water in the storage box 330 flows from the first flowing water portion 333 and the second flowing water portion 334 of the storage box 330 into the washing tub 500 through the bellows portion 551, the drain port 552, and the check valve 553.

(Structure of detergent case)
10 is a top view of the detergent case of the washing machine according to the first embodiment of the present invention, FIG. 11 (a) is a sectional view taken along the line BB of FIG. 10, and FIG. 11 (b) is a cross-sectional view taken along the line CC of FIG. It is a sectional view.

This will be described with reference to FIGS. 9 to 11. The detergent case 400 is provided with a handle portion 440, and can be taken out from the storage box 330 by pulling the handle portion 440. The detergent case 400 includes a powder detergent case 410 on the front surface, and a bleach case 420 and a softener case 430 on the left and right sides of the back surface of the powder detergent case 410.

The upper end edge of the powder detergent case 410 has an elliptical shape 411, and each of the four corners R-shaped 413 draws a large arc. The powder detergent case 410 has a height difference, and the elliptical shape 411 is surrounded by a steep high wall 412 as compared with the bottom surface into which the powder detergent is charged.

A bleach case 420 and a softener case 430 are provided on the left and right behind the powder detergent case 410, and a narrow flow path 414 is provided so as to pass between them. Narrow flow path walls 415 are provided on the left and right sides of the narrow flow path 414.

The bleach case 420 is composed of a bleach lid portion 421 and a bleach tube shape 422, and is fitted with the bleach lid portion 421 and the bleach tube shape 422 to form a siphon shape. Then, when the bleach case 420 is filled with water at the time of water supply, the agent flows out from the bleach case 420.

Similarly, as shown in FIG. 9, the softener case 430 is composed of a softener lid portion 431 and a softener lid circular tube shape 432, and includes a softener lid portion 431 and a softener lid circular tube. By fitting with the shape 432 and forming a siphon shape, water is supplied from the second water guide cylinder 312 at the time of water supply, and when the softener case 430 is filled with water, the agent flows out from the softener case 430. .. The second water bottle 312 is turned on so that the softener is added during rinsing in the washing sequence, and the timing of injecting water into the softener case 430 is adjusted.

The bottom surfaces of the detergent powder case 410 and the narrow flow path 414 are sloped so as to decrease from the front to the rear. This is to make it easier to flush the detergent powder. The rear end of the narrow flow path 414 is provided with a bent portion 417 with ribs 416 so as to wrap around the rear of the softener case 430, and a slit portion 418 is provided at the tip thereof. The detergent solution gets over the rib 416 and falls into the storage box 330 from the slit portion 418. After the water supply is stopped, water falls from the slit portion 418, so that no residual water pool is generated.

Further, since the rear end of the narrow flow path 414 is provided with a bent portion 417 by ribs 416 so as to wrap around behind the softener case 430, foreign matter (for example, a hairpin or the like) has entered the powder detergent case 410. Even so, foreign matter can be secured at the bent portion 417 and the rib 416, and it is possible to prevent the foreign matter from flowing into the storage box 330, the drainage path 550, and the washing tub 500.

In the present embodiment, the rear end of the narrow flow path 414 is formed so as to wrap around the rear of the softener case 430, but the rear end of the narrow flow path 414 wraps around the rear of the bleach case 420. Even if it is formed, it can have the same effect.

(Mechanism of water flow)
The flow of water to the water supply unit 300 will be described.

In the washing step, the first water bottle 311 is opened by driving the water supply valve 310, and water flows into the first path FP. The water flowing in from the first path FP passes through the first flow path 351, is throttled from the first hole portion 371, and is supplied to the second flow path 352.

The water that has passed through the second flow path 352 is poured into the powder detergent case 410 from five locations of the second hole 372 formed above the high wall 412. The powder detergent charged into the powder detergent case 410 is dissolved while being concentrated in the central portion of the powder detergent case 410 by water injected from above the high wall 412 of the elliptical shape 411 of the powder detergent case 410. When the flow rate at the time of water injection is strong and the water injection pressure is high, the powder detergent scatters in all directions due to the water injection pressure, but the powder detergent case 410 has a large square R shape 413 and a second hole. Since water is injected from the portion 372 toward the outer peripheral portion of the elliptical shape 411, the effect of preventing undissolved residue at the corner portion is obtained.

Further, the powder detergent is discharged to the narrow flow path 414 as a drainage route while being concentrated in the center of the powder detergent case 410. The narrow flow path 414 has a narrow flow path area as compared with the elliptical shape 411 of the powder detergent case 410, the high wall 412 surrounding the narrow flow path 414 and the narrow flow path wall 415 are high, and the water accumulated by water injection is at a high position. It uses energy to flow into the narrow channel wall 415. Since the narrow flow path wall 415 drains water at a constant speed toward the back surface of the product, the powder detergent collected on the bottom surface of the powder detergent case 410 also dissolves and moves along a constant flow direction, so that it dissolves even under a low flow rate. The configuration has few remaining.

Next, the water that has passed through the first flow path 351 and has not passed through the first hole portion 371 is split into the third flow path 353 and the fourth flow path 354. The water flowing into the third flow path 353 is poured from the third hole 373 into the bleach case 420 of the detergent case 400. In the bleach case 420, water is filled by water injection from the third hole 373, and is drained toward the drainage path 550 at the back of the storage box 330 by the siphon circular tube shape composed of the bleach lid 421. ..

The water diverted to the fourth flow path 354 is injected into the fifth hole 375 connected to the drying path, passes through a heat exchanger (not shown in the drawing), and washes away dust and dirt accumulated in the heat exchanger. At the same time, water is injected into the fourth hole 374 formed at the tip of the protrusion 370 and discharged into the drainage path 550. Since the water injected into the drainage path 550 is injected with a height difference from the sixth hole 376, the injection pressure is higher than that of the other holes, and the speed is increased to the drainage path 550 in the open state. It rises and is ejected.

The water from the fourth hole 374, which is ejected by increasing the speed by falling from the fourth flow path 354 to the protrusion 370, is dissolved in the powder detergent case 410 and flows into the detergent liquid and the foaming space 332. (Drainage path 550 and the bottom of the storage box 330) collide and stir, and air is contained and foaming is generated. The foamed detergent solution passes through the bellows portion 551, the drain port 552, and the check valve 553, and is charged into the washing tub 500. The foamed detergent solution directly falls on the clothes in the washing tub 500. By expanding the surface area of the surfactant with bubbles, the probability that the surfactant adheres to the stains on the clothes is increased, and the effect on stain removal is enhanced more quickly.

The flow velocity of the water ejected from the fourth hole 374 is mainly determined by the amount of water stored in the internal space of the protrusion 370. Even if the flow rate of tap water supplied from the water supply valve 310 fluctuates, the water falls from the fourth flow path 354 to the protrusion 370 and is ejected from the fourth hole 374. A stable stirring force is given to the detergent solution in the foaming space 332. Further, since the detergent solution is agitated by the force of the water ejected linearly, a large amount of water is not consumed for the agitation function.

Next, in the rinsing step, the second water bottle 312 is opened by driving the water supply valve 310, and water flows into the second path SP. The water supplied from the second water bottle 312 passes through the fifth flow path 355 and is injected into the sixth hole 376 and the seventh hole 377. Then, water is poured from the sixth hole 376 into the softener case 430 of the detergent case 400 and from the seventh hole 377 into the powder detergent case 410. In the softener case 430, water is filled by water injection from the seventh hole portion 377, and is drained toward the drainage path 550 at the back surface of the storage box 330 by the siphon circular tube shape composed of the softener lid portion 431. ..

By driving the second water bottle 312, it is possible to switch to the first water bottle 311 and it is possible to avoid mixing the detergent solution and the softener in the washing tub 500. After washing and rinsing the clothes with the first water bottle 311 and eliminating the detergent solution residue on the clothes, the second water bottle 312 is started in the final rinsing process to transfer the softener to the washing tub 500. It is possible to put it in and improve the finish effect.

The bath pump 314 is used to reuse accumulated water such as bath water. First, the first water bottle 311 is started from the water supply valve 310 to fill the bus pump called priming water with water, prevent the bus pump rotor from idling, and suck up the accumulated water. After the priming water is filled, the bus pump 314 sucks up the accumulated water by driving the rotor.

The sucked up water passes through the sixth flow path 356 and is injected from the eighth hole 378. Water is poured into the powder detergent case 410 in the detergent case 400, the detergent is dissolved, and the water is drained to the drainage path 550.
