Description

Washing machine {WASHING MACHINE}

The present invention relates to a washing machine, and more particularly, to a fully automatic washing machine having a function of automatically inserting detergents (detergent, bleach, flexible finish, etc.) contained in a detergent container when water is supplied into a washing tank in which laundry is accommodated. will be.

In general, the automatic washing machine puts detergent into the washing tank together with water supplied through an external hydrant or a bath water pump during the water supply of the washing stroke, and a flexible finishing agent into the washing tank during the water supply of the final rinsing stroke. An input device is provided. The same applies to the tornado washing machine having a structure in which a washing tank having an open top is rotated about an almost vertical axis, as well as a drum washing machine having a structure in which a drum containing laundry is rotated about an almost horizontal axis.

For example, the drum type washing machine described in Patent Literature 1 is provided with a pull-out detergent container on the upper portion of the front face of the outer case provided with a door for opening and closing the laundry inlet. The detergent container has a powdered detergent container, a liquid detergent container and a finishing agent container arranged in a left-right direction and is partitioned, and when the detergent (powder detergent or liquid detergent) or a flexible finish agent is filled, the detergent is washed. At appropriate times during the administration, these detergents are automatically fed into the tank.

On the other hand, the same drum type washing machine, for example, the drum type washing machine described in Patent Literature 2 is provided with openings on the outer circumferential surfaces of the drum and the outer tub, respectively, and the laundry opening is formed on the upper surface of the outer case as in a conventional tornado washing machine, and a cover for opening and closing the same The sieve is installed to open to the rear side. In this drum type washing machine, a detergent container and an operation panel are arranged on both left and right sides of the lid, and the detergent container is formed in a pull-out type having a long shape in the front-rear direction so as not to interfere with opening and closing of the lid. Thus, the drum type washing machine provided with the cover body on the upper surface of the outer case can obtain the same ease of use as the general whirlwind type washing machine, and can also obtain high cleaning performance, water saving, etc., which are the characteristics of the drum type washing machine.

The detergent container of the drum type washing machine of this patent document 2 is divided into three in the front-back direction, and consists of a finishing agent accommodating part, a liquid detergent accommodating part, and a powder detergent accommodating part from the front side. The flexible finish is used to improve the finish of the laundry or to prevent static electricity, and in many cases, it is not actually used. In addition, in general households, powder detergents are used predominantly than liquid detergents. Therefore, the highest frequency used among these three accommodating parts is the powder detergent accommodating part. However, in such a drum type washing machine, it is necessary to pull out a lot of the detergent container toward the front in order to fill the detergent container with powder, so that it is cumbersome for the user and the possibility of being caught in the drawn detergent container is also high.

In addition, commercially available drum washing machines provided with an upper lid on the upper side have a detergent container which is long in the front-rear direction and divided into three in the front-rear direction. There is also a thing (refer nonpatent literature 1). In this case, unlike the drum-type washing machine described above, there is no effort to pull the detergent container forward when filling the detergent. However, the distance from the user's position to the powder detergent receiving portion of the detergent container is far. In particular, the drum type washing machine having such a structure is disposed at a considerably rear side of the upper surface because the size (length) in the front and rear direction tends to be larger than that of the drum type washing machine or tornado washing machine in which the door is provided on the front surface as described in Patent Document 1. In the case where the powder detergent is filled in the powder detergent container, the powder detergent may be spilled on the way, or the powder detergent may enter the liquid detergent container or the finish agent container in the front, and the convenience of use thereof is not good.

The present invention has been made to solve the above problems, and its main object is to provide a washing machine that can improve the convenience of use of the detergent container of the detergent injecting device for automatically introducing detergents into the washing tank. In addition, another object of the present invention is to provide a washing machine capable of reducing the dissolution of detergents, such as detergents are appropriately put into the washing tank while improving the convenience of use of the detergent container. Further, another object of the present invention is to provide a washing machine that can reduce the manufacturing cost by simplifying the structure of the detergent injecting device.

The present invention made to solve the above problems, an outer case forming an outer shape, a washing tank made of an outer tank installed in the outer case and a rotating material installed in the outer tank and the laundry is accommodated therein, and the water supply to the washing tank In the washing machine provided with a detergent inlet for passing at least a portion of the water through the detergent container when the detergent is carried out in the washing tank,

The detergent container has an elongated shape in the front-rear direction of the washing machine, and is divided into at least three powder detergent accommodating parts, liquid detergent accommodating parts and finishing agent accommodating parts, among which the powder detergent accommodating part is disposed at the most front side. do.

In the washing machine which concerns on this invention, the powder detergent accommodating part is arrange | positioned in front of the detergent container of a long shape in the front-back direction, ie, the side which is close to the position where a user stands. Thus, for example, in the case where the detergent container is formed in a draw-out type, a powder detergent can be put in if the detergent container is pulled out to a position where only the front powder detergent accommodating part is opened without drawing much detergent container. In addition, in the case where the detergent container is not a draw-out type, for example, the structure is opened or closed by a cover body that also serves as a dedicated or top cover, the powder detergent container is located relatively close to the user, so that the powder detergent weighed with a measuring spoon or the like is stored in the powder detergent container. The distance to convey to a part is short, and can prevent it from flowing in a middle or putting into another accommodating part.

Moreover, the washing machine which concerns on this invention is one specific embodiment, Comprising: The water supply means which introduces the water supplied from the exterior to each accommodating part of the said detergent container, and receives the water and detergents which flow out from each accommodating part, and supplies it to a washing tank. And a water supply port for discharging water into the respective receiving portions of the detergent container, and an auxiliary soil for flowing water to the water supply port without passing through the detergent container. It is preferable to set it as the structure which has a water port.

Placing the powder detergent receiving portion on the front side has the advantages as described above, while the following disadvantages. That is, powder detergents generally do not dissolve in water and do not flow well as compared to liquid detergents such as liquid detergents or cast finishes. Therefore, even if the powder detergent is dropped into the water supply port by being pushed from the water supply means to the powder detergent container, there is a possibility that the powder detergent is not transported to the washing tank and part of the powder detergent is dissolved in the water supply port. According to the configuration in which the auxiliary water jet is installed to solve this problem, even if the powder detergent spilled with water from the powder detergent container of the detergent container is dissolved in the water supply port, water supplied directly from the auxiliary water jet to the water supply port. It flows down or melt | dissolves in the water, and can prevent a detergent from remaining in a water supply port part.

In this configuration, the outlet of the water from the water supply port portion to the washing tank is disposed on the rear side, and the auxiliary water jetting port is disposed on the front side of the outlet of the water and detergent from the powder detergent receiving portion to the water supply port portion. It is further more preferable if it is set as a structure.

According to this configuration, since the powder detergent which has been dropped from the powder detergent container to the water supply port and melted is present in the middle of the water supplied from the auxiliary water discharge port to the water supply port, flows toward the water outlet of the water supply port, By this, the outflow or dissolution of the powder detergent can be performed more reliably.

Moreover, in a liquid detergent accommodating part, a finishing agent accommodating part, etc., as described in patent document 2 etc., a liquid agent is made to flow out from each accommodating part using siphon action. In this case, even if the strength of the water supplied to the receiving portion is weak, when the water level is above the predetermined level, the liquid agent flows smoothly along the water to the water supply port. However, in the powder detergent container, since the powder detergent is flowed using the strength of water, if the strength of the water supplied from the main water discharge port of the distillation unit to the powder detergent container is weak, the powder detergent does not flow well from the container to the water supply port. Poor dissolution tends to occur in the receiving portion.

In the washing machine according to the present invention, it is preferable that the main water jetting port of the water purifying means is provided at a position lower than the water supply valve for supplying water supplied from the outside to the water purifying means.

According to this configuration, since the flow of water supplied from the external water supply at a predetermined water pressure is not broken until the powder detergent container is reached through the water supply valve and the water feeding means, the water is discharged from the main water discharge port into the powder detergent container. Water can be discharged strongly. Thereby, the powder detergent contained in the powder detergent accommodating part can be smoothly flowed out to a water supply port part, and the dissolution in a accommodating part can be reduced.

In addition, it is preferable that the auxiliary water jetting port is provided at the lowest position of the water passage provided in the water supply means, and the configuration also serves as a drain opening for discharging water remaining in the water passage.

According to this configuration, for example, when the water supply valve for supplying water to the water supply means is closed, water remaining in the water passage of the water supply means reaches the auxiliary water discharge port by gravity and is discharged to the water supply port portion. Therefore, it is possible to prevent water from remaining in the water passage of the dilution means after the end of the washing operation.

In addition, as an embodiment of the washing machine according to the present invention, the water supply means having a water passage for guiding the water supplied from the outside into each of the receiving portion of the detergent container, the washing tank receiving the water and detergent flowing out from each receiving portion Further comprising a water supply port for supplying to the upper surface plate member which forms a part of the outer case and covers the upper portion of the outer tub integrally formed in a substantially concave shape, the water supply means inside the water supply port It can be set as the structure which accommodated.

In general, since the water passage means is provided with a passageway therein, a plurality of members are joined by vibrating welding, ultrasonic welding, thermal welding, or the like, but leakage may occur due to incomplete bonding. In the configuration of the above embodiment, since the water supply port in which the water supply means is accommodated is integrally formed with the top plate member, there is no seam that may cause water leakage. Therefore, even if water leaks from the water supply means, the water flows through the water supply port to the washing tank. Water can be prevented from leaking out of the electrical casing or the outer case. In addition, the water supply port can be manufactured as a separate member and manufactured at a lower cost than when mounted on the top plate member or other parts.

In addition, in the washing machine having such a configuration, a laundry inlet for inserting or removing laundry into the inner tank is provided in the upper plate member, and the detergent container is stored in the water supply port so that the washing means is blocked, and the laundry inlet is further provided. The top cover for opening and closing may be configured to cover the upper portion of the detergent container.

According to this structure, since the upper cover which opens and closes a laundry input opening can be used as the cover body of a detergent container, cost can be reduced compared with the case where the cover body of a detergent container is provided separately.

Hereinafter, a drum type washing machine according to an embodiment of the present invention will be described with reference to the drawings.

The two dampers 13 which support the lower part of the outer tub 11 in 12 and the front-back direction are hold | maintained so that it can oscillate suitably. Inside the outer tub 11, the horizontal drum C, in which both end surfaces of the substantially cylindrical outer circumferential surface on which a plurality of through-holes, which are the inner tub of the present invention, are almost occluded, is occluded, is centered on a horizontal axis C extending in the left and right directions. It is rotatably installed. That is, in the drum type washing machine according to the present embodiment, the outer tub 11 and the drum 14 correspond to the washing tub of the present invention. The main shaft 15 fixed to the center of the left end face of the drum 14 is supported by the bearing 18 held by the first bearing case 17 fixed to the left end face of the outer tub 11. On the other hand, the auxiliary shaft 16 fixed to the center of the right end surface of the drum 14 is supported by the bearing 20 held by the second bearing case 19 fixed to the right end surface of the outer tub 11. The horizontal axis C is formed by the main axis 15 and the auxiliary axis 16.

The rotor 212 of the drum motor 21, which is an outer rotor-type DC motor, is fixed to the front end of the main shaft 15 protruding to the left from the left end surface of the outer tub 11, and the first bearing case 17 also serving as a motor stand. ), The stator 211 of the drum motor 21 is fixed. When a driving current is supplied to the stator 211 from a control circuit (not shown), the rotor 212 rotates accordingly, and the drum 14 is rotationally driven through the main shaft 15 at the same rotational speed as the rotor 212. .

The outer tub opening 111 which is opened and closed by the outer tub door 112 is provided in the position which coincides with the laundry inlet 4 of the outer case 1 from the upper part of the outer peripheral surface of the outer tub 11 to the diagonal front. Moreover, although the drum opening 141 is provided also in the outer peripheral surface of the drum 14, the drum opening 141 is opened and closed by the drum door 142 which consists of two door bodies which have a Kannon opening structure back and forth. Since the drum 14 is rotatable, a drum lock mechanism 22 is provided below the stator 211 so that the drum 14 remains stationary at a position where the drum opening 141 is radially coincident with the outer tub opening 111. ) Is installed. The stop position of the drum 14 is determined by engaging the engaging convex portion formed in the rotor 212 with the engaging convex portion advancing upward from the drum lock mechanism 22.

The washing machine as described above is a drum-type washing machine, the upper cover 2 installed on the upper surface of the outer case 1, the outer door 112 installed on the outer circumferential surface of the outer tub 11, and the drum door 142 installed on the outer circumferential surface of the drum 14. ) It is formed in a structure in which laundry can be put into or taken out of the drum 14 from above or diagonally forward with three open. Thus, the same convenience of use as a tornado washing machine is achieved.

Next, a configuration of a water supply device having a detergent injecting mechanism that is characteristic of the drum washing machine will be described with reference to FIGS. 2, 3, and 6 to 13.

Fig. 6 is a partial top perspective view of a state where the detergent container 40 is removed from the drum type washing machine, Fig. 7 is a side sectional view of the entire upper part at the position of the water supply port 1b, and Fig. 8 is a water supply unit 50 and a water supply valve. (8) is an external perspective view, FIG. 9 is an external perspective view of the member constituting the water supply unit 50, FIG. 10 is a right side view of the water supply unit 50, and FIG. 11 is a detergent container 40 in the water supply port 1b. 12 is a front longitudinal cross-sectional view of the state where the detergent container 40 is attached to the water supply port 1b, and FIG. 13 is an external perspective view of the detergent container 40. FIG.

As shown in Figs. 6 and 7, the part of the outer case 1 of the drum type washing machine of the present embodiment is stretched in the front-rear direction to the left and rear of the top plate member 1a made of synthetic resin in which a laundry inlet 4 is formed. And the concave water supply port portion 1b in which the bottom wall is inclined downward toward the rear is integrally formed. The outlet 1d is provided in the lower end of the rear wall 1c of this water supply port 1b, and the outlet 1d is connected to the outer tank 11 through the water supply pipe 23 shown in FIG. That is, the water which flowed into the water supply port part 1b flows into the water supply pipe 23 from the outlet 1d, and is supplied to the outer tank 11 through the water supply pipe 23. Since the water inlet port 1b is formed integrally with the top plate member 1a, there is no seam where leakage may occur.

In addition, as shown in FIG. 7, a recess 1f is formed immediately in front of the water supply port portion 1b of the upper plate member 1a, which causes the top cover 2 to be downwardly formed in two sections. Contact with the shaft 3b which protrudes can be avoided.

The left side wall surface of this water supply port part 1b is provided in the back of the rear wall 1c, and forms the water flow path between the water supply valve 8 and bath water pump 9, and the detergent container 40 which are not shown in FIG. The water supply unit 50 which is a water supply means of this invention for storing is accommodated. As shown in Fig. 8, the water supply unit 50 has a structure in which the left and right main members 50a and the sub members 50b, which are made of two synthetic resins, are joined by ultrasonic welding (vibration welding, thermal welding, or the like). It has, but a hollow channel is formed between these two members 50a and 50b.

Specifically, a rib for forming a water passage is complicatedly formed inside the main member 50a positioned on the right side, and thus, the tap water inlet for detergent is formed inside the water supply unit 50. The water supply passage 521 for detergents communicated to 511, the bath water passage 523 communicated with the bath water inlet 513, and the water passage 522 for the finish agent communicated with the finisher water inlet 512 are disposed. do. In addition, in the water supply passage 521 for detergent, the main water jetting port 534 for fluid detergent and the main water jetting port 531 for powder detergent are sequentially installed in accordance with the flow of water. In addition, in the bath water passage 523, the main water jetting port 533 for the liquid detergent and the main water jetting port 532 for the powder detergent are provided in order according to the flow of water. Further, the main water jetting port 535 for the finishing agent is provided at the end of the water passage 522 for the finishing agent. Further, an auxiliary water jetting port 536 opened downward is provided at the end of the detergent tap water flow passage 521.

The detergent tap water inlet 511 and the finisher tap water inlet 512 arranged in the horizontal direction are connected to two outlets of the water supply valve 8. Further, the bath water inlet 513 is connected to the outlet of the bath water pump 9 via a hose not shown. The height of the powdered detergent main water jetting port 531 provided in the detergent tap water passage 521 is lower than the position of the detergent tap water inlet 511. In addition, the position of the auxiliary water jet hole 536 is located at the lowest in the tap water passage 521 for detergent, which brings the action as described below. As shown in FIG. 8, when the assembly unit consisting of the water supply unit 50 and the water supply valve 8 is mounted to the water supply port 1b, the state shown in FIG. 6 is achieved, and at this time, the rear wall of the water supply port 1b. A part of the protrusion piece 55 extended in the horizontal direction (right side) from 1c and the main member 50a of the water supply unit 50 is superposed | polymerized. That is, the notch 1e for inserting the water supply unit 50 is formed in the rear wall 1c of the water supply port 1b, and when the water collects in the water supply port 1b, this notation 1e and the water supply are made. Water may flow from the distance between the unit 50 to the rear side, that is, to the water supply valve 8 side, but by providing a portion overlapping the section 55 and the rear wall 1c as described above, the gap is made very small. This prevents the outflow of water.

Although the outflow of water is not completely prevented through this overlapping portion, it is possible to avoid the massive outflow of water that extends to at least the electrical contact on the rear side of the water supply valve 8. In addition, as shown in FIG. 7, even if a small amount of water flows into the water supply valve 8 side, since the drain hole 1g is formed in the bottom wall below the water supply valve 8 of the upper plate member 1a. It discharges smoothly through the drain hole 1g.

Detergent container 40 is attached to the upper portion of the water supply port (1d) as a removable material, as shown in Figure 13, the tray portion 40a divided into three in the front and rear direction, and the upper portion of the tray portion 40a It consists of a decorative plate portion 40b coupled to. These three compartments include a powder detergent accommodating portion 41 for accommodating powder detergent from the front side, a liquid detergent accommodating portion 42 for accommodating a liquid detergent or a liquid bleach (liquid injected simultaneously with the detergent during washing), It is the finish agent accommodating part 43 for accommodating a flexible finishing agent (liquid injected into the last rinse), and the letter which shows the content of each accommodating part 41, 42, 43 is displayed on the makeup board part 40b. .

As shown in Fig. 11, the bottom wall 411 of the powder detergent accommodating portion 41 is gently inclined downward toward the rear, and a large detergent outlet 412 through which water including detergent flows out from the bottom of the rear wall. Is open. When water is supplied to tap water or bath water in a state where powder detergent is accommodated in the powder detergent accommodating portion 41 and water flows into the accommodating portion 41, the powder detergent is supplied through the detergent outlet 412 according to the flow of water. Outflow to 1b).

On the other hand, at the bottom walls of the liquid detergent accommodating portion 42 and the finishing agent accommodating portion 43, cylindrical portions 421 and 431 penetrating up and down in the center thereof are respectively installed, and the base portions thereof are provided on the cylindrical portions 421 and 431. The cylindrical caps 422 and 432 covering the top, leaving the top covered. A narrow gap is formed between the inner circumferential side wall surfaces of the caps 422 and 432 and the outer circumferential side wall surfaces of the cylindrical portions 421 and 431, and the liquid detergent accommodating portion is formed through the gap and the through holes of the cylindrical portions 421 and 431. The inner side and the outer side of the 42 and the finishing agent accommodating part 43 communicate with each other. Therefore, even if the liquid liquid having fluidity is accommodated in the liquid detergent container 42 and the finish agent container 43, the liquid agent does not flow out before the water supply, and the water supply of tap water or bath water is performed so that the water level in the receivers 42 and 43 is reduced. Only when the above water accumulates, the water flows downward along the liquid agent, that is, into the water supply port portion 1b.

A portion corresponding to the main water jetting holes 531, 532, 533, 534, 535 is opened on the left wall surface of each of the accommodation portions 41, 42, 43 (for example, the opening 44 of FIG. 12). }, The water discharged from each said main water discharge port 531, 532, 533, 534, 535 through this opening is comprised so that it may enter into each accommodation part 41, 42, 43. In addition, as shown in Fig. 12, non-shaped protrusion pieces 54 are formed diagonally downward on the upper portions of the main water jetting holes 531 and 532 for powder detergent of the water supply unit 50. If the protrusion piece 54 is not present, the water discharged from the main water jetting ports 531 and 532 is strongly discharged in the horizontal direction when water is supplied while the detergent container 40 is not attached to the water supply port 1b. Although it is easy to be scattered, if the stone piece 54 is installed, the outflow direction of water is changed downward, and it can reduce the splashing of water upward even if the detergent container 40 is not mounted. In addition, when the detergent container 40 is properly mounted, the water discharged from the main water jetting holes 531 and 532 falls to the bottom piece 411 of the powder detergent accommodating portion 41 and fits into the stone pieces 54. Therefore, the powder detergent in the bottom wall 411 can be spilled favorably.

Next, an example of the operation of the water supply device having the above configuration will be described. Before starting washing, the user fills the appropriate amount of powder detergent into the powder detergent container 41 (or liquid detergent container 42, for example) while the top cover 2 is opened as shown in FIG. The appropriate amount of the liquid detergent is filled in with the appropriate amount of the flexible finishing agent in the finishing agent accommodating portion 43 as necessary. Generally, powder detergent is the most frequently used, and powder detergent is more likely to spill than liquid because it uses a measuring spoon to collect the detergent and transport it to the detergent container 40. Therefore, in the drum type washing machine of the present embodiment, the powder detergent accommodating portion 41 is disposed on the frontmost side of the detergent container 40, thereby reducing the trouble of filling the detergent container 40 with the powder detergent, and flowing the detergent. It is preventing.

When the washing operation is started, the tap water supplied from the water supply line through the water supply valve 8 as the water supply of the washing stroke is sent to the tap water supply passage 521 for detergent. In the water supply using the bath water, the bath water pump 9 is operated, but at this time, the tap water is first sent to the detergent tap water passage 521. At the time of tap water supply, water is sent from the main water jetting port 531 for powder detergent to the powder detergent container 41. Therefore, when the powder detergent is accommodated in the powder detergent accommodating portion 41, the powder detergent is pushed into the water supply port portion 1b by the water falling against the stone pieces 54 and falling through the water supply pipe 23 as described above. It is supplied in the outer tub 11. As described above, the main water jetting port 531 for the powder detergent is located at a lower position than the water supply valve 8. Accordingly, the water supplied from the water supply valve 8 to the detergent tap water flow passage 521 reaches the main water jetting port 531 for powder detergent without spontaneously breaking down, and is spouted with force. Thereby, since the powder detergent can be flowed favorably, the dissolution failure of the powder detergent in this accommodating part 41 can be prevented. In addition, since water is also supplied from the main liquid jetting port 534 for the liquid detergent to the liquid detergent accommodating portion 42, when the liquid detergent is accommodated in the liquid detergent accommodating portion 42, the liquid is discharged by the siphon action as described above. The detergent flows into the water inlet 1b and is supplied into the outer tank 11 through the water supply pipe 23 like the powder detergent.

On the other hand, when tap water is initially supplied during bath water supply, part of the water is branched and supplied to the bath water pump 9 as a lake. Given a lake, the bath water pump 9 aspirates the bath water through the bath water inlet 7 and sends the sucked water to the water supply unit 50. Therefore, the bath water supplied to the bath water passage 523 flows to the water supply port 1b together with the powder detergent or the liquid detergent like the tap water. In addition, the water supply valve 8 supplies water for a predetermined time when the water is supplied to the bath water and stops the water supply. After that, the bath water sucked by the bath water pump 9 is supplied to the water supply port 1b through the detergent container 40. ) Into the outer tub 11.

In the case of the liquid detergent, the detergent from the water inlet 1b to the outer tank 11 is smoothly flowed out. In the case of the powder detergent, the powdered detergent dropped to the water inlet 1b is not dissolved and the bottom wall of the water inlet 1b is not dissolved. Easy to leave In particular, when the powder detergent flows to the front side than the detergent outlet 412 and fits into the water inlet 1b, it is difficult to flow the detergent to the outlet 1d through the water flowing out of the detergent outlet 412. In the drum type washing machine of the present embodiment, in this case, the powder detergent is spilled into the water discharged from the auxiliary water jetting port 536 located at the most front side to the water supply port part 1b. That is, since the water discharged from the auxiliary water jetting port 536 flows backward along the inclination of the water supply port 1b, that is, toward the outlet 1d, the water discharged from the auxiliary water jetting port 536 fits into the water supply port 1b and is located ahead of the detergent outlet 412. Even the existing powder detergent can be sent to the outlet 1d. Therefore, the poor dissolution of the powder detergent in the water supply port part 1b can be reduced.

In addition, in the case of bath water supply, the bath water is not discharged from the auxiliary water discharge port 536, but a small amount of water (compared to tap water supply) for supplying a lake to the bath water pump 9 even when bath water is supplied is used as a detergent tap water passage ( Since it flows to 521, when a part of this tap water discharges from the auxiliary discharge port 536, it is effective for flowing out the powder detergent in the water supply port part 1b. Of course, an auxiliary water jet may be provided at the end of the bath water passage 523, or an auxiliary water jet may be provided by joining the ends of the bath water passage 523 and the detergent water passage 521.

In rinsing strokes other than the final rinse stroke, bath water supply or tap water supply is performed as described above. In the water supply of the rinsing stroke, both the powdered detergent and the liquid detergent in the detergent container 40 flow out and are empty, so that the tap water is supplied to the powder detergent accommodating portion 41 and the liquid detergent accommodating portion 42 during the subsequent rinsing water supply. Even though passing through), water containing no detergent is supplied into the outer tub 11. Of course, even in such water supply, poor dissolution of the powder detergent in the water supply port portion 1b through the water discharged from the auxiliary water discharge port 536 can be further reduced.

In the final rinsing stroke, tap water is supplied to both the detergent tap water inlet 511 and the finish tap water inlet 512 by the water supply valve 8. Therefore, tap water is also supplied to the finishing agent accommodating part 43 of the detergent container 40, the flexible finishing agent melt | dissolved in this water is aspirated by siphon action with water, and it flows out into the water supply port part 1b, and the water supply pipe 23 It is supplied into the outer tub 11 through).

Thus, tap water or bath water containing a detergent (powder detergent or liquid detergent) at the time of water supply of the washing stroke, tap water or bath water at the time of water supply of the rinsing stroke other than the final rinse stroke, and flexible water at the time of water supply of the final rinse stroke The tap water containing agent can be supplied to the outer tank 11, respectively.

As described above, the auxiliary water jetting hole 536 is disposed at the lowest position of the water passage in the water supply unit 50. Therefore, when the washing operation is finished and all the water supply is finished, the water remaining in the water passage is discharged from the auxiliary water discharge port 536 to the water supply port 1b. That is, at this time, the auxiliary jetting port 536 functions as a drain hole of the water passage of the water supply unit 50. Therefore, since no water remains in the water passage of the water supply unit 50, the inside of the water supply unit 50 can be kept clean. In addition, for example, it is possible to prevent the water from freezing in the water passage of the water supply unit 50 in an extremely cold region in winter.

The above embodiment is an example of the present invention, it is apparent that appropriate changes or modifications can be made within the scope of the present invention. For example, the above embodiment is an example in which the present invention is applied to a drum type washing machine, but the present invention may be applied to a tornado washing machine. In addition, the present invention can also be applied to a structure in which the lid of the detergent container is separate from the upper lid for opening and closing the laundry inlet, or the drawable detergent container. In addition, the frequency means of this invention is not limited to the form which formed the channel through a rib like the said Example, For example, it uses what is a pipe etc. In addition, although the powder detergent accommodating part of a detergent container is arrange | positioned in front, the arrangement of other accommodating parts is not specifically limited, For example, a liquid detergent accommodating part and a finishing agent accommodating part are not arranged in the front-back direction like the said Example. It may be a configuration arranged in the left and right directions without.

According to the washing machine according to the present invention, since the powder detergent accommodating portion is disposed in the front of the detergent container, the powder detergent accommodating portion can be easily filled into the powder detergent accommodating and used easily at the highest frequency. Therefore, the usability of a detergent container can be improved. In addition, by providing an auxiliary water jet in addition to the main water jet, the water jet means can reduce the dissolution of the powder detergent in the water supply port while arranging the powder detergent container in the front side. Thereby, since an appropriate amount of powder detergent can be thrown into a washing tank at the time of washing operation, sufficient washing | cleaning performance can be exhibited. In addition, since undissolved powder detergent can also be reduced to flow into the washing tank at the time of rinsing, it also contributes to the improvement of the rinsing performance. In addition, since the adhesion of the powder detergent in the water inlet port is reduced, the labor of maintenance such as cleaning can be reduced.

In addition, since the water supply port is integrally formed in the upper plate member and the water supply means is accommodated in the water supply port, even if the water supply means is incompletely bonded, a weak portion of the water in the outer case is avoided or water is leaked out of the device. This can be prevented from spreading. In addition, it is possible to provide a cheaper product by reducing the manufacturing cost.
