(Structure of detergent box)

Figure 10 is a top view of the detergent box of the washing machine in Embodiment 1 of the present invention, Figure 11A is a sectional view of 11A-11A of Figure 10, and Figure 11B is a sectional view of 11B-11B of Figure 10.

9 ~ FIG. 11A, FIG. 11B, for description. The lotion box 400 has a handle part 440 , and can be taken out from the storage box 330 by pulling the handle part 440 . In the detergent box 400, the powder detergent box 410 is provided in the front, and the liquid detergent box 420 and the softener box 430 are provided in the left and right of the back side of the powder detergent box 410.

The upper end of the powder lotion box 410 is an oval shape 411, and the R-angle shape 413 on the four sides all draws a larger arc. The powder lotion box 410 has a height difference, and compared with the bottom surface where the powder lotion is put in, the elliptical shape 411 is surrounded by an outer peripheral wall surface 412 that forms a curved surface with a steep slope.

Behind the powder lotion box 410, a liquid lotion box 420 and a softener box 430 are provided on the left and right, and a narrow flow path 414 is provided to pass between them. Narrow channel walls 415 are provided on the left and right of the narrow channel 414 .

The liquid lotion box 420 is composed of a liquid lotion cover 421 and a liquid lotion tube shape 422, and the liquid lotion cover 421 and the liquid lotion tube shape 422 are fitted to form a siphon (siphon) shape, Thereby, when water is supplied, when the liquid lotion box 420 is filled with water, the liquid lotion mixed with water will flow out from the liquid lotion box 420 .

Similarly, as shown in FIG. 9, the softener box 430 is composed of a softener cover 431 and a softener cover circular tube shape 432, and the softener cover 431 and the softener cover circular tube shape 432 are fitted to form The shape of the siphon tube is such that when water is supplied, the softener mixed with water will flow out from the softener box 430 when the softener box 430 is filled with water by the second water guide cylinder 312 . In the washing process, the time point of turning on (ON) the second water guide cylinder 312 to inject water into the softener box 430 in order to inject softener during rinsing can be adjusted.

The bottom surfaces of the powder lotion box 410 and the narrow channel 414 are sloped so as to become lower from the front to the rear. This is for the sake of making the powder lotion flow easily. In addition, the rear end of the narrow flow path 414 is provided with a bent portion 417 on the rib portion 416 to go around the softener box 430 , and a slit portion 418 is provided at its front end. The lotion will go over the rib 416 and drop from the slit 418 into the storage box 330 . In addition, since the water falls from the slit portion 418 after the water supply is stopped, no accumulation of water remains.

Also, since the rear end of the narrow flow path 414 is provided with a bent portion 417 on the rib 416 to go around the back of the softener box 430, even if foreign matter (such as hairpins, etc.) enters the powder lotion box 410, it can be The curved portion 417 and the rib portion 416 are used to secure foreign matter, thereby preventing foreign matter from flowing into the storage box 330 , the drainage path 550 and the washing tank 500 .

In addition, in the present embodiment, although the rear end of the narrow flow path 414 is formed so as to wrap around the softener box 430, the rear end of the narrow flow path 414 may be formed to wrap around the liquid detergent box 420. have the same effect. (structure of water flow)

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

In the cleaning step, the first water guiding cylinder 311 is opened by driving the water supply valve 310 to allow water to flow into the first path FP. The water flowing in from the first path FP passes through the first flow path 351 , and the flow rate is throttled from the first hole portion 371 to be supplied to the second flow path 352 .

The water that has passed through the second flow path 352 is poured into the powder detergent box 410 from the five second hole portions 372 formed above the outer peripheral wall surface 412 . The powdered lotion that has been thrown into the powdered lotion box 410 is concentrated toward the center of the powdered lotion box 410 by the water injected from above the outer peripheral wall surface 412 of the elliptical shape 411 of the powdered lotion box 410, and is absorbed. dissolve. When the flow rate during water injection becomes stronger and the water injection pressure becomes higher, the powder lotion will be scattered toward the four corners by the water injection pressure, but due to the large R-angle shape 413 formed in the powder lotion box 410, and Water is poured from the second hole portion 372 toward the outer peripheral portion of the ellipse 411 , so that the effect of preventing the dissolution residue on the corner portion can be obtained.

In addition, the powdered lotion is collected in the center of the powdered lotion box 410 and discharged toward the narrow flow path 414 as a drainage path. Compared with the elliptical shape 411 of the powder lotion box 410, the flow path area of the narrow flow path 414 is narrow, and the surrounding peripheral wall 412 and the narrow flow path wall 415 are very high, and the water accumulated by water injection will use the high potential energy to dissipate. Inflow toward the narrow channel wall 415 . In the narrow flow path wall 415, since the water is discharged toward the back of the product at a constant speed, the powder detergent accumulated on the bottom surface of the powder detergent box 410 will also dissolve and move along a certain flow direction, so it becomes even at a low flow rate. Under the dissolved residue there is still very little composition.

Next, the water passing through the first flow path 351 and not passing through the first hole portion 371 is divided into the third flow path 353 and the fourth flow path 354 . The water flowing toward the third flow path 353 is poured into the liquid detergent box 420 of the detergent box 400 from the third hole portion 373 . In the liquid lotion box 420, it is filled with water by the water injection from the third hole portion 373, and by the shape of the siphon tube formed by the liquid lotion cover portion 421, it faces toward the back of the storage box 330. Drain path 550 drains water.

The water diverted to the fourth flow path 354 is injected into the fifth hole 375 leading to the drying path, and passes through a heat exchanger not shown in the figure to wash away dirt or dust accumulated in the heat exchanger. At the same time, water is injected into the fourth hole portion 374 formed at the front end of the protruding portion 370 and is ejected toward the drain path 550 . Since the water injected into the drain path 550 is ejected from the sixth hole 376 with a height difference, the injection pressure is higher than that of other holes, so that the water is injected toward the open drain path 550 at an increased speed.

The water from the fourth hole 374 collides and stirs with the liquid lotion dissolved and flowing from the powder lotion box 410 in the foaming space 332 (the bottom of the drain path 550 and the storage box 330), thereby containing air and generating bubbles. Bubbles, the aforementioned water from the fourth hole portion 374 is the water that is ejected by increasing the speed by falling from the fourth flow path 354 to the protruding portion 370 . The foamed lotion liquid will pass through the telescopic part 551 , the drain port 552 , and the check valve 553 , and be thrown into the washing tank 500 . The foamed lotion liquid will directly fall on the clothes that have been put into the washing tank 500 . By expanding the surface area of the surfactant with foam, the probability of the surfactant adhering to the dirt on the clothes is increased, and the decontamination effect is improved faster.

In addition, the flow velocity of the water ejected from the fourth hole portion 374 is mainly determined by the amount of water stored in the inner space of the protruding portion 370 . Assuming that even if the flow rate of tap water supplied by the water supply valve 310 fluctuates, the water will still fall from the fourth flow path 354 to the protruding portion 370 and be sprayed from the fourth hole portion 374, so that the bubble space 332 can be adjusted. The lotion liquid exerts a stable stirring force. Also, since the lotion liquid is stirred by the force of the water jetted in a linear form, a large amount of water is not consumed by the stirring function.

Next, in the flushing step, the second water guiding cylinder 312 is opened by driving the water supply valve 310 to allow water to flow into the second path SP. The water supplied from the second water guiding cylinder 312 passes through the fifth flow path 355 and is injected into the sixth hole portion 376 and the seventh hole portion 377 . Then, water is poured into the softener case 430 of the detergent case 400 from the sixth hole portion 376 , and water is poured into the powder detergent case 410 from the seventh hole portion 377 . The softener box 430 is filled with water by filling water from the seventh hole 377, and is directed to the drainage path at the back of the storage box 330 by the shape of a siphon tube formed by the softener cover 431. 550 drain.

By driving the second water guide cylinder 312 , it can be switched with the first water guide cylinder 311 , so as to avoid mixing of lotion liquid and softener in the washing tank 500 . Use the first water guiding cylinder 311 to carry out the steps of washing and rinsing the clothes. After removing the residue of the lotion on the clothes, start the second water guiding cylinder 312 in the final rinsing step, and put the softener into the washing tank 500 to lift the laundry detergent. Handling effects will become possible.

The tank pump 314 is used to reuse accumulated water such as bath water. First, start the first water guide cylinder 311 from the water supply valve 310 to fill the tank pump with water called starting water, so as to prevent the idling of the tank pump rotor and absorb accumulated water. After the starting water is filled, the tank pump 314 will absorb accumulated water through the driving of the rotating member.

The sucked water passes through the sixth flow path 356 and is injected from the eighth hole 378 . Water is poured into the powder detergent box 410 inside the detergent box 400 to dissolve the lotion, and the water is drained toward the drain path 550 .

In addition, in the above-mentioned embodiment, although the liquid detergent box 420 for injecting the liquid lotion is described, it is not limited to the liquid lotion, and may be a bleaching agent input box for injecting the bleaching agent.
