A main sectional view is shown. FIG. 14 is a cross-sectional perspective view of a main part of a water supply section of a general top load washing machine. FIG. 15 shows a main cross-sectional view of a general top load washing machine when a detergent storage case is pulled out. FIG. 16 is an exploded perspective view of essential parts of a general front load washing machine. FIG. 17 shows a cross-sectional view of essential parts of a general top load washing machine.

Hereinafter, the configuration of a general top load washing machine will be described with reference to FIGS. 13 to 17.

The washing machine main body 102 rotatably accommodates the washing tub 101 therein, and an upper housing 103 is mounted on the upper portion of the washing machine main body 102 to substantially cover the entire upper portion of the washing machine main body 102. At approximately the center of the upper casing 103, there is formed a clothes inlet 104 which is integrally formed with the upper casing 103 and extends downward in the washing tub 101. A lid 105 that covers the entire upper part of the clothing inlet 104 is openably and closably attached to the upper housing 103. The washing tub 101 is rotated and stopped by the motor 110.

A detergent accommodating case 106 for accommodating a detergent is disposed in the upper housing 103 in a position near the clothes inlet 104 so as to be freely drawn out. A flow path structure 107 is formed above the detergent storage case 106, and tap water is guided by the flow path configuration 107 to flow down to each part of the detergent storage case 106. The flow path structure portion 107 constitutes an upper surface of the flow path structure portion 107, constitutes a flow path structure portion upper surface 107a for preventing water leakage from the flow path structure portion 107, and a lower surface of the flow path structure portion 107, and includes a detergent. It is composed of a flow path structure lower surface 107b through which water supplied to the housing case 106 flows down. Below the detergent containing case 106, detergent dissolving means 108 is configured. The detergent containing case 106 mixes tap water and detergent to form an aqueous detergent solution 109.

The upper surface 107a of the flow path structure portion and the detergent dissolving means 108 are integrally formed, open toward the washing tub 101 side, and have a bottom on the opposite side of the washing tub 101.

As a result, even when the tap water pressure is high and the flow rate flowing through the flow path structure 107 is large, the detergent accommodating case 106 and the detergent aqueous solution 109 overflowing from the detergent dissolving means 108 are transferred to the washing machine main body 102 and the upper casing 103. Since it is prevented from overflowing, it is prevented that the electric parts such as the motor 110 are splashed with water to cause insulation failure.

The detergent containing case 106 has a first drainage portion 111 formed at one end located on the opposite side of the clothes inlet 104, and the detergent aqueous solution 109 is drained from the first drainage portion 111 to the detergent dissolving means 108. doing.

The detergent dissolving means 108 has a second drain portion 112 formed at one end located on the side of the clothes inlet 104. The detergent aqueous solution 109 that has flowed down on the surface of the detergent dissolving means 108 is drained from the second drainage section 112 to the clothes inlet 104.

The detergent dissolving means 108 is inclined downward from the first drainage portion 111 toward the second drainage portion 112. The second drainage section 112 is arranged outside the clothes insertion port 104 and inside the washing tub opening inner wall 113 at the opening end of the washing tub 101 on the clothes insertion port 104 side.

As a result, the detergent aqueous solution 109 is drained from the second drain portion 112 to the inside of the washing tub opening inner wall 113, so that the detergent aqueous solution 109 is transmitted between the washing tub 101 and the washing machine main body 102, and the motor 110 is discharged. It prevents electrical parts such as water from being exposed to water and resulting in poor insulation.

The detergent dissolving means 108 is held from below by a holding member 114. The holding member 114 is attached to the upper housing 103 by means of tabs, screws, etc., not shown, after previously assembling the detergent dissolving means 108, electric parts such as lead wires, sensors, etc., not shown, into a unit state.

As a result, the holding member 114, the detergent dissolving means 108 and the like are assembled into a unit state and assembled to the upper housing 103, which facilitates manufacturing.

As shown in FIG. 14, the detergent dissolving means 108 is provided with ribs 120 extending from the bottomed side of the detergent dissolving means 108 toward the open side. A slit 121 is opened at the bottom of the detergent accommodating case 106, and a rib 120 is inserted in the slit 121.

By passing the detergent aqueous solution 109 through the gap between the rib 120 and the slit 121, the detergent is efficiently dissolved and the cleaning performance is improved. In addition, since the rib 120 slides in the slit 121 every time the user inserts and removes the detergent containing case 106, it is possible to prevent the detergent from being fixed between the rib 120 and the slit 121 and clogging. Further, the detergent dissolving means 108 is inclined downward from the first drainage portion 111 toward the second drainage portion 112, and the rib 120 extends from the bottomed side of the detergent dissolving means 108 toward the open side. Since the detergent dissolving means 108 is formed in such a manner, the mold withdrawing direction and the rib 120 extending direction can be made the same, and the detergent dissolving means 108 can be easily molded.

As shown in FIG. 15, the sliding surface 131 of the detergent containing case is slidably supported on the sliding surface 130 of the detergent dissolving means. The claws 135a and 135b of the flow path structure portion arranged on the left and right of the flow path structure portion 107 are arranged so as to contact the edge portion 134 of the detergent storage case when the detergent storage case 106 is most pulled out.

Accordingly, when the detergent is put into the detergent containing case 106, the position of the detergent containing case 106 is regulated by bringing the tabs 135a and 135b of the flow path structure portion 107 into contact with the edge portion 134 of the detergent containing case 106. And, it is easy to put detergent by eliminating rattling. When cleaning the detergent accommodating case 106, after pulling out the detergent accommodating case 106, the diagonally upward is lifted to remove the edge portion 134 of the detergent accommodating case 106 from the tabs 135a and 135b of the flow path structure 107, and the detergent accommodating case 106 is removed. The 106 is removable.

FIG. 16 shows another conventional washing machine, for example, a front-loading washing machine. The claw 135 of the flow channel structure 107 is provided in the center of the flow channel structure 107, on the surface facing the detergent containing case 106, and contacts the claw 137 of the detergent containing case when the detergent containing case 106 is most pulled out. .. The detergent accommodating case 106 has a vertically long shape.

Thus, when the detergent containing case 106 is pulled to the position where it comes into contact with the claw 137, the left and right wall surfaces of the rear portion of the detergent containing case 106 are regulated by the inner wall of the detergent dissolving means 108 to eliminate rattling. , Easy to put detergent. When removing the detergent storage case 106, the beam portion 36 of the detergent storage case 106 that elastically holds the tab 137 of the detergent storage case 106 is pushed down, and the tab 137 of the detergent storage case 106 is removed from the tab 135 of the flow path structure 107. Removed and removed.

As shown in FIG. 17, above the washing tub 101, a water supply means 151 for supplying shower water 150a, 150b to the clothes is provided. The water in the washing tub 101 is pumped up by a pump (not shown), pressurized and sent to the water supply means 151. The water supply means 151 further has a circular first discharge port 152 provided on the bottom surface and a second discharge port 153 opened on the outer peripheral surface in a substantially horizontal direction. A throttle 154 is provided in front of the first outlet 152 and the second outlet 153, and the flow rate is increased by the throttle 154.

As a result, the shower water 150a jetted from the first discharge port 152 and spread downward, and the shower water 150b jetted from the second discharge port 153 and spread horizontally are applied to the laundry 155 in the washing tub 101. The shower water 150a and 150b are evenly applied so that the shower water can be efficiently washed.

However, in such a conventional washing machine, when the tap water pressure is high, the flow rate flowing down from the flow path structure portion 107 to the detergent accommodating case 106 is large, so that the detergent aqueous solution 109 is present in the gap between the rib 120 and the slit 121. The detergent flows out of the first drainage section 111 into the detergent dissolving means 108 faster than it is passed through. For this reason, the detergent is supplied to the washing tub 101 without being melted, and there is a problem that it is difficult to improve the cleaning performance. Further, when the tap water pressure is low, the flow rate flowing down from the flow path structure 107 is small, and the water flows out from the slit 121 before the water level of the detergent accommodating case 106 rises. Only the detergent melts and flows down, and the detergent on the upper side remains undissolved forever, which poses a problem that the detergent cannot be effectively dissolved. Therefore, it is difficult to commercialize the detergent because the detergent dissolution and the cleaning performance are likely to vary depending on the tap water pressure.

The present invention solves the above-mentioned conventional problems, and provides a washing machine with a simple configuration, which efficiently dissolves detergent and improves washing performance even when tap water pressure is high or low. The purpose is to

In order to solve the above-mentioned conventional problems, the washing machine of the present invention includes a detergent accommodating case, a mixing chamber in which a detergent aqueous solution is generated by mixing detergent and water, and a detergent in the detergent aqueous solution is crushed by spraying water. It is divided into a crushing chamber and a partition wall, and the detergent solution is discharged downward to the bottom of the crushing chamber to remove the detergent.
Look including long plurality of slits in the out direction of the housing case, a plurality of pins formed on the flowing water surface below the detergent housing case, the pin is obtained by a partially inserted structure for a slit. As a result, even when the water pressure is high, the water and the detergent are mixed in the mixing chamber before the detergent solution flows into the crushing chamber, so that the detergent is easily dissolved, and the force of water jetting into the crushing chamber is strong. , More easily dissolve the detergent. When the water pressure is low, the water is partitioned by the partition wall, so until the water level exceeds the partition wall, water and detergent are mixed in the mixing chamber and sent to the grinding chamber in order, and the detergent can be finely ground by the slit. So it is easy to dissolve detergent. This can prevent the cleaning performance from varying due to water pressure.

INDUSTRIAL APPLICABILITY The washing machine of the present invention has a simple structure and efficiently dissolves the detergent even if the tap water pressure fluctuates, so that the washing performance can be prevented from varying.

The surface of the claw 35 and the claw 37 opposite to the contacting surface is inclined with respect to the sliding direction of the detergent accommodating case 6. Accordingly, when the detergent containing case 6 is attached to the flow path structure 7, the inclined surfaces of the claws 35 and 37 come into contact with each other, and as the detergent containing case 6 is inserted, the beam portion 36 of the detergent containing case 6 is elastic. The tab 37 of the detergent accommodating case 6 and the tab 35 of the flow path structure part are locked by the tab 37 overcoming the tab 35.

At the left and right ends of the flow path structure 7, support means 38 of the flow path structure 7 are formed extending downward along the sliding direction of the detergent accommodating case 6, and the inner surface of the support means 38 is It is located close to the outer walls of the first storage chamber 14 and the second storage chamber 15.

At the left and right ends of the detergent accommodating case 6, the position suppressing means 39 of the detergent accommodating case 6 is formed extending upward along the sliding direction of the detergent accommodating case 6, and the inner surface of the position suppressing means 39 is It is close to the outer wall of the support means 38 of the road structure 7.

From the outer side to the inner side, the position suppressing means 39 of the detergent accommodating case 6, the supporting means 38 of the flow path structure portion, the outer wall of the first accommodating chamber 14 and the second accommodating chamber 15, the first accommodating chamber 14 and the second accommodating chamber 14 Accommodation room 15
Further, the claw 37 of the detergent accommodating case 6 and the claw 35 of the flow path structure portion are sequentially arranged so as to be sandwiched therebetween.

As described above, the claw 37 (first locking means) of the detergent storage case 6 and the claw 35 (second locking means) of the flow path structure portion 7 are located substantially at the center of the detergent storage case 6. However, the support means 38 of the flow path structure portion 7 and the position restraining means 39 of the detergent storage case 6 are located close to each other on the left and right end sides of the detergent storage case 6 which are located away from the claws 35 and 37. There is.

The support means 38 of the flow path structure 7 is integrally formed on the flow path structure lower surface 7b, and extends in the front-back direction of the flow path structure lower surface 7b, that is, in the sliding direction of the detergent accommodating case 6, and the flow path structure lower surface 7b. Is extended over the length of the entire length, and is formed in a rail shape having substantially the same cross section.

As a result, the lower surface 7b of the flow path structure portion, the sliding surface 34 of the flow path structure portion 7, the claws 35 of the flow path structure portion 7, and the supporting means 38 of the flow path structure portion 7 are integrally configured. Further, the detergent accommodating case 6, the sliding surface 31 of the detergent accommodating case 6, the position suppressing means 39 of the detergent accommodating case 6, the beam portion 36 of the detergent accommodating case 6, and the claw 37 of the detergent accommodating case 6 are integrally configured. It

A part of the bottom surface of the first storage chamber 14 is opened to form a drainage hole 40 for the powder detergent. The drainage hole 40 of the powder detergent faces the running water surface 8a of the detergent dissolving means 8 on the drainage hole 29 side of the water splash suppressing wall 28a.

At the time of washing, when water is supplied from the flow path structure portion 7 to the first storage chamber 14 and the powder detergent is flowed, part of the water and the detergent flows down from the drain hole 40 of the powder detergent, and the detergent dissolving means. It is supplied to the washing tub 1 through the drain hole 29 through the flowing water surface 8a.

After supplying a predetermined amount of water to the washing tub 1, when the water supply from the flow path structure portion 7 is completed, the water remaining in the first storage chamber 14 flows down from the drainage hole 40 of the powder detergent and is supplied to the washing tub 1. .. Even if there is a partition wall 23 on the drain side of the first storage chamber 14, the first storage chamber 14 is not left with residual water, so that the next time the user puts powder detergent into the first storage chamber 14, the surface of the first storage chamber 14 Since it is dry, it is easy to add detergent and it is easy to use.

The flow path at one end of the flow path structure portion 7 on the side of the clothes inlet 4 constitutes a lateral flow path 41, and the lateral flow path 41 extends laterally around the washing tub 1 to the left and right ends of the detergent storage case 6. It is formed by extending in the direction.

The water supplied from the water supply valve 18 passes through the flow path including the first downflow hole 25 and the second downflow hole 26 in the flow path structure portion 7, and then passes through the flow path throttle portion 42 to flow in the lateral direction flow path. Water is supplied to 41. The left and right ends of the lateral flow passage 41 respectively extend downward to form a first water pipe portion 43 and a second water pipe portion 44.

Near the lower ends of the first water pipe portion 43 and the second water pipe portion 44, there is a spherical surface portion 45, and the spherical surface portion 45 has the central axes of the first water pipe portion 43 and the second water pipe portion 44. At the center, the inner surface is formed with substantially the same radius. A part of the spherical surface portion 45 opens obliquely downward toward the washing tub 1 side to form a first horizontal opening portion 46 and a second horizontal opening portion 47. The first water pipe portion 43 and the first horizontal opening portion 46 form a first water supply means 48, and the second water pipe portion 44 and the second horizontal opening portion 47 form a second water supply means 49. I am configuring.

The first water supply means 48 and the second water supply means 49 are arranged adjacent to the left and right of the detergent storage case 6. As a result, the shower water 50 flows into the laundry 55 in the washing tub 1 from the first horizontal opening 46 and the second horizontal opening 47 toward the washing tub 1.

The first horizontal opening portion 46 and the second horizontal opening portion 47 are opened obliquely downward toward the washing tub 1 side on the spherical portion 45 centered on the central axes of the water pipe portion 43 and the water pipe portion 44. Water flows vertically to the first horizontal opening 46 and the second horizontal opening 47 around the central axes of the water pipe 43 and the water pipe 44. The spherical surface portion 45, the first horizontal opening portion 46, and the second horizontal opening portion 47 respectively constitute urging means for determining the jet direction of water.

The washing tub 1 has a first rotating state in which it is rotated clockwise by the motor 10 and a second rotating state in which it is rotated counterclockwise by the motor 10, and the water supply valve 18 is opened during washing and rinsing. During these rotations, the shower water 50 is supplied to the laundry 55 in the washing tub 1.

As a result, in the first rotation state, the laundry 55 on the left side of the washing tub 1 moves toward the first water supply means 48 on the left side of the washing tub 1 as well. Similarly, in the second rotation state, the laundry 55 on the right side of the washing tub 1 moves toward the second water supply means 49 also on the right side of the washing tub 1 in a direction approaching.

End openings 51 are formed at the left and right ends of the first horizontal opening 46 and the second horizontal opening 47. The end opening 51 is formed in a substantially circular shape, and has an opening size larger than the vertical opening size of the first horizontal opening 46 and the second horizontal opening 47. The first horizontal opening 46 and the end opening 51, and the second horizontal opening 47 and the end opening 51 are formed in a long hole shape having a large opening area at both ends. As a result, an opening shape similar to the opening shape of the tip of the rubber hose is formed when the tip of the rubber hose is pinched with fingers and the water is spread in a fan shape and discharged.

The opening area S1 including the first horizontal opening 46 and the left and right end openings 51 is smaller than the flow passage cross-sectional area S2 of the first water pipe portion 43, and the opening area of the flow passage throttle portion 42. It is set larger. The flow passage cross-sectional area S2 of the first water pipe portion 43 is set to be substantially the same as the flow passage cross-sectional area of the lateral flow passage 41.

Thereby, the water flowing to the lateral flow passage 41, the first water pipe portion 43, and the first horizontal opening portion 46 via the flow passage throttle portion 42 has no narrowed portion, that is, the flow passage cross section is Since there is no place to narrow, it is possible to make it difficult for the water pressure in the flow path to drop. When the tap water pressure is low and the flow rate is low, the velocity of the shower water 50 from the first horizontal opening 46 is also low, and the decrease in the water in the first water pipe portion 43 is also slow.

Since the opening area S1 including the first horizontal opening 46 and the left and right end openings 51 is set to be smaller than the flow passage cross-sectional area S2 of the first water pipe portion 43, the shower water 50 From the velocity of, the flow velocity flowing in the first water pipe portion 43 becomes slower in inverse proportion to the cross-sectional area S2. When the pressure due to the water level in the first water pipe section 43 and the speed of the shower water 50 are balanced, the water level in the first water pipe section 43 becomes stable, and the water level in the first horizontal opening section 46 becomes A certain amount of water pressure will continue to be applied. The same applies to the second horizontal opening 47.

The first horizontal opening 46 has a jaw 52 that constitutes the lower half. The inner side of the jaw portion 52 has a throttle surface 53 that extends a part of the spherical surface portion 45 to the edge of the first horizontal opening portion 46 and narrows the cross-sectional area of the flowing water path. The outside of the jaw portion 52 has a retreat surface 54 that retreats downward from the edge of the first horizontal opening portion 46 in the extending direction of the first water pipe portion 43. The same applies to the second horizontal opening 47.

Below the washing tub 1, there is an agitating blade 56 that applies a rotational force to the laundry to wash it. Below the stirring blade 56, there is a detergent dissolving blade 57 configured by extending radial ribs toward the opening of the washing tub 1. During the washing operation, the stirring tub 56 is rotated by the motor 10 without rotating the washing tub 1. As a result, the detergent dissolving blade 57 also rotates.

On the side wall of the washing tub 1, a washing tub detergent inlet 58 is supported. In the state in which the detergent input port 58 of the washing tub is opened, one end of the detergent input port 58 of the washing tub extends outward from the opening of the washing tub 1 to dispose the introduced detergent in the washing tub 1. Let it flow down. The detergent flows down through a detergent flow path 59 formed in a gap outside the washing tub 1 and drops to a position facing the detergent melting blade 57.

The operation and action of the washing machine configured as described above will be described.

1 and 2, the detergent accommodating case 6 is accommodated between the detergent dissolving means 8 formed by extending a part of the upper housing 3 downward and the flow path structure portion 7, so that the detergent aqueous solution 9 Flows on the running water surface 8a of the detergent dissolving means 8 and does not exceed the flow path structure upper surface 7a. As a result, water overflowing from the detergent accommodating case 6 is applied to electrical parts such as the water supply valve 18 and the operating portion 19 arranged at a position higher than the flowing surface 8a of the detergent dissolving means 8 of the upper housing 3, resulting in poor insulation. Can be prevented. Since the flow path structure upper surface 7a and the flow path structure lower surface 7b are formed in a substantially plate shape, the welding device is easy to downsize, easy to manufacture, and has no unevenness, so that the welding quality is stable. Cheap.

Since the detergent dissolving means 8 is formed integrally with the upper casing 3, it is possible to prevent water leakage, and to promote the dissolution of the detergent aqueous solution 9 in water and the detergent while flowing through the running water surface 8a of the detergent dissolving means 8. The cleaning performance can be improved.

Since the second waterproof wall 17, the first waterproof wall 16, the first drainage portion 11, and the second drainage portion 12 are arranged in order from above, the first drainage portion 11 is the second drainage portion. Located higher than 12. Therefore, the aqueous detergent solution 9 does not stay on the running water surface 8a of the detergent dissolving means 8 and flows down into the washing tub 1. Therefore, sufficient drainage can be achieved when passing through the first drainage portion 11, and the first drainage portion 11 Except for the above, water or the detergent aqueous solution 9 does not overflow from the detergent containing case 6, so that water does not easily leak. The first waterproof wall 16 is located at a position higher than that of the first drainage unit 11. For this reason, even if water or detergent solution 9 overflows from the detergent storage case 6, it is easy to drain the water in the first drainage portion 11, so that water is unlikely to leak from the first waterproof wall 16. Further, the second waterproof wall 17 is located higher than the first waterproof wall 16. Therefore, even if water or detergent solution 9 overflows the first waterproof wall 16, the water level is unlikely to rise to the second waterproof wall 17, so that water leakage from the second waterproof wall 17 is prevented. Therefore, it is possible to prevent the water supply valve 18, the operation unit 19, and electric parts such as the motor 10 arranged in the upper housing 3 from being splashed with water to cause insulation failure.

When viewed from the center side of the washing tub 1, the clothes inlet 4, the sliding surface 34 (second supporting means) of the flow path structure 7, the front edge 33 of the operating portion, the opening 32, and the detergent dissolving means are arranged in this order. The front edge of the sliding surface 30 (first supporting means), the second drainage portion 12, the inner wall 13 of the washing tub opening, and the flowing surface 8a of the detergent dissolving means 8 are arranged. The detergent accommodating case 6 is slidably supported not only by the sliding surface 30 (first supporting means) of the detergent dissolving means 8 but also by the sliding surface 34 (second supporting means) of the flow path structure portion 7. To be done. Thus, in order to integrate the detergent dissolving means 8 with the upper housing 3, the depth dimension of the detergent dissolving means 8 must be shortened, that is, the sliding surface 30 (first support) of the detergent dissolving means 8. Even when the detergent accommodating case 6 can be supported only outside the opening portion 32 when the means) is short, the detergent accommodating case 6 is slid out to the sliding surface 34 of the flow channel structure 7 when the detergent accommodating case 6 is greatly pulled out. Since the detergent can be supported by the moving surface 34 and the detergent storage case 6 does not fall off, the user can reliably put the detergent in.

Since the sliding surface 34 (second support means) of the flow path structure portion 7 constitutes a part of the flow path structure portion 7, the detergent accommodating case 6 is separated from the detergent dissolving means 8 and the flow path structure portion 7. Since it can be slidably supported, the sliding surface 30 of the detergent dissolving means 8 (the first supporting means) can be obtained simply by positioning the detergent dissolving means 8 and the flow path structure portion 7 with a claw or a screw. ) And the sliding surface 34 (second supporting means) of the flow path structure portion 7 and the sliding surface 31 of the detergent accommodating case 6 are deviated from each other to prevent the detergent accommodating case 6 from being difficult to pull out. be able to.

In FIG. 1, by introducing the detergent into the detergent inlet 58 of the washing tub 1 to cause the detergent to flow down to the detergent dissolving blade 57, and by rotating the stirring blade 56 during washing, the detergent dissolving rotating with the stirring blade 56. The blade 57 allows the detergent to be dissolved. When the tap water pressure is high, when the tap water pressure is low, the detergent is put into the detergent housing case 6 that is openably and closably housed in the upper housing 3, and the detergent is dissolved and supplied to the washing tub 1 when tap water is supplied. When water is supplied in a bucket or the like without using water, the detergent is put into the detergent inlet 58 of the washing tub 1 and the detergent can be dissolved by the rotation of the stirring blade 56 during the washing operation, which is convenient.

In FIG. 3, the mixing chamber 24 and the crushing chamber 22 are partitioned by a partition wall 23, and a first downflow hole 25 through which water flows down into the mixing chamber 24 and a second downflow hole 26 through which water flows down into the crushing chamber 22. Are provided so as to communicate with the flow path structure 7, and the detergent solution 9 is made to flow from the slit 21 that flows downward to the bottom of the crushing chamber 22. As a result, regardless of the state of the detergent, for example, even when the detergent is moist and clumped, the detergent in the detergent aqueous solution 9 promotes dissolution until it becomes smaller than the slit 21 and is washed. It can be supplied to the tank 1, and the cleaning performance can be improved.

When the tap water pressure is low, the water pressure in the flow path structure portion 7 is low, and the flow velocity of water exiting from the first downflow hole 25 and the second downflow hole 26 communicating with the first downflow hole 25 is low, the water level in the mixing chamber 24 is also slow. The detergent in the mixing chamber 24 ascends and does not exceed the partition wall 23 at a time, is dissolved by the water from the first downflow hole 25 for a sufficient time, and is then sent to the crushing chamber 22. Therefore, even when the tap water pressure is low, the dissolution can be promoted and the water can be supplied to the washing tub 1, and the cleaning performance can be improved.

When the tap water pressure is high, the water pressure of the flow path structure portion 7 is high, and the flow velocity of the water flowing out from the first downflow hole 25 and the second downflow hole 26 communicating with the first downflow hole 25 is high, the water level in the mixing chamber 24 is It rises quickly and the detergent in the mixing chamber 24 crosses the partition wall 23 in a short time. Even in this case, the water and the detergent may be mixed until the partition wall 23 is exceeded. Since the flow velocity of water from the second downflow hole 26 is also high, the detergent is vigorously pulverized in the pulverization chamber 22, and the detergent can be dissolved in a short time. Therefore, even if the tap water pressure is high, dissolution can be promoted and the water can be supplied to the washing tub 1, and the cleaning performance can be improved.

A pin 20 is erected on the running water surface 8a of the detergent dissolving means 8 toward the slit 21, and the tip of the pin 20 is inserted into the slit 21. As a result, the detergent finely crushed until it passes through the slits 21 is further finely pulverized while passing between the pins 20 on the flowing water surface 8a of the detergent dissolving means 8, so that the detergent can be efficiently dissolved. Since the longitudinal direction of the slit 21 is substantially the same as the sliding direction of the detergent accommodating case 6, the user fixed the slit 21 by taking the detergent accommodating case 6 in and out each time the detergent is inserted into the washing machine. Since the detergent can be peeled off by the sliding pin 20 and the detergent can be prevented from sticking to the slits 21 and clogging, efficient detergent dissolution can be realized for a long period of time.

The detergent aqueous solution speed adjusting wall 27 is provided above the crushing chamber 22 region. As a result, even when the tap water pressure is high and the flow rate flowing down from the first downflow hole 25 of the flow path structure portion 7 is large, the flow of the detergent aqueous solution 9 that vigorously exceeds the partition wall 23 is crushed by the detergent aqueous solution speed adjusting wall 27. The flow can be changed in the direction of the chamber 22 and downward in FIG. Therefore, the aqueous detergent solution 9 easily stays within the range of the crushing chamber 22, and it is possible to suppress the detergent aqueous solution 9 from flowing down over the crushing chamber 22 before the dissolution of the detergent, so that the detergent can be efficiently dissolved and the cleaning performance can be improved. Can be improved.

In FIG. 5, the water splash prevention wall 28a is formed by extending in the flowing direction in the vicinity of the position on the flowing surface 8a of the detergent dissolving means 8 facing the first downflow hole 25. Accordingly, when the detergent storage case 6 is forgotten to be mounted and the vehicle is driven, the water flows down from the first downflow hole 25 and splashes in all directions on the flowing surface 8a of the detergent dissolving means 8, but a part of the water splash suppressing wall. The flow changes in the upward direction when hitting 28a. For this reason, it is possible to suppress the splashing toward the front of the device from the opening on the side of the second drainage portion 12 of the flowing water surface 8a of the detergent dissolving means 8.

Since one end of the water splash suppressing wall 28a on the second drain portion 12 side extends in a substantially J-shape in a direction different from the flowing direction, the water flows down from the first downflow hole 25 and the water flows into the detergent dissolving means. When splashing in all directions on the surface 8a, it is possible to prevent water from splashing from the drain portion 12 side. The water splash restraint walls 28b and 28c extend in a substantially C-shape in a direction different from the flowing water direction so as to surround a position facing the second downflow hole 26. Thereby, when the water from the second downflow hole 26 splashes in all directions on the running water surface 8a of the detergent dissolving means, a part of the water hits the water splash suppressing walls 28b and 28c, and the flow changes upward. For this reason, it is possible to prevent the user from bouncing forward of the device, so that the user in front of the device will not get wet even when the detergent storage case 6 is removed.

Since the detergent splashing walls 28b and 28c are opened in the flowing direction of the detergent aqueous solution 9, the detergent aqueous solution 9 does not remain. A drainage hole 29 communicating with the washing tub 1 is provided in the running water surface 8a of the detergent dissolving means 8 near the water splash suppressing wall 28a which is bent in a substantially J shape at one end on the second draining section 12 side. The inner wall 13 of the first washing tub opening is open to the inside. Thereby, a part of the water flowing on the running water surface 8a of the detergent dissolving means can be drained toward the washing tub 1 without overflowing to a place other than the washing tub 1, and can be dammed by the water splash suppressing wall 28a, Alternatively, it is possible to prevent the detergent aqueous solution 9 whose flow direction is suppressed from remaining on the running water surface 8a of the detergent dissolving means 8 and then drying to adhere only the detergent to the running water surface 8a of the detergent dissolving means 8. ..

The running water surface 8a of the detergent dissolving means 8 is formed by extending a part of the upper casing 3 downward, the periphery thereof is surrounded by the peripheral wall 8b of the detergent dissolving means 8, and the upper portion thereof is covered with the flow path structure portion 7. Further, the flow path structure portion 7 is waterproofed by a second waterproof wall 17 formed integrally. As a result, the detergent dissolving means 8 and the water splash suppressing walls 28a, 28b, 28c are molded in the mold in the vertical direction of FIG. 5, that is, in the same direction as the opening direction of the mold of the upper housing 3. Since it can be molded by moving the mold, it can be molded easily without using a slide mold.

Further, in FIG. 4, since the drain hole 29 is opened at a position facing one of the first downflow holes 25, the water flowing down from the first downflow hole 25 must hit the running water surface 8 a of the detergent dissolving means 8. Since the water can be made to flow down directly into the washing tub 1, it is possible to prevent water from splashing in front of the equipment at the flowing water surface 8a of the detergent dissolving means 8 even if the detergent accommodating case 6 is not attached.

In FIG. 6, when the detergent containing case 6 is pulled out, the position is regulated by the claw 37 of the detergent containing case 6 and the claw 35 of the flow path structure portion 7. As a result, the detergent and the softening agent can be put into the first storage chamber 14 and the second storage chamber 15 each time with a predetermined withdrawal amount, which is convenient. Further, the user can remove the detergent accommodating case 6 simply by pushing down the beam portion 36 of the detergent accommodating case 6, which is convenient. Even if the tab 37 of the detergent accommodating case 6 and the tab 35 of the flow path structure are increased in size, they can be removed by simply pushing down the beam section 36 of the detergent accommodating case 6, thus improving the usability.

Since the claw 37 of the detergent storage case 6 and the claw 35 of the flow path structure portion are located at substantially one central position of the detergent storage case 6, the detergent storage case 6 is less likely to rattle to the left and right, and the beam of the detergent storage case 6 does not easily rattle. The operation of pushing down the portion 36 can be performed with one hand and can be easily removed, which is convenient. Since the beam portion 36 of the detergent accommodating case 6 can be visually recognized with the detergent accommodating case 6 pulled out, the method of removing the detergent accommodating case 6 can be visually easily determined and the usability is improved.

When the detergent accommodating case 6 is attached, the beam portion 36 of the detergent accommodating case 6 elastically bends downward and rides over, so that the claw 37 of the detergent accommodating case 6 and the claw 35 of the flow path structure part 7 are engaged. Stop. Since the user can mount the detergent storage case 6 at a predetermined position by pushing it in, the user does not need to apply a force other than the sliding direction of the detergent storage case 6, which is convenient.

The detergent accommodating case 6 has a claw 37 (first engaging means) of the detergent accommodating case 6 and a claw 35 (second engaging means) of the flow path structure portion 7 substantially at the center thereof. The support means 38 of the flow path structure 7 and the position restraining means 39 of the detergent containing case 6 are provided close to each other at positions apart from the claws 37 and 35, that is, at the left and right ends of the detergent containing case 6. As a result, even if the distance from the claw 37 of the detergent storage case 6 to the rear end surface of the detergent storage case 6 is shortened in order to make the clothes insertion port 4 large, the detergent storage case 6 can be easily inserted into the detergent storage case 6 so that the detergent can be easily input. When opened, the supporting means 38 of the flow path structure 7 and the position suppressing means 39 of the detergent accommodating case 6 are in close proximity to each other, so that the detergent accommodating case 6 has less rattling and the detergent can be easily dispensed.

The supporting means 38 of the flow channel structure 7 has the same cross section in the front-back direction of the flow channel structure lower surface 7b, that is, in the sliding direction of the detergent accommodating case 6 over the entire length of the flow channel structure lower surface 7b. It is formed in a rail shape and is brought into contact with the left and right end portions of the first storage chamber 14 and the second storage chamber 15 of the detergent storage case 6. Accordingly, even when the detergent containing case 6 is designed to be horizontally long in order to increase the amount of the detergent to be added, the movement of the left and right end portions of the detergent containing case 6 is suppressed when the detergent containing case 6 is slid back and forth. Therefore, the detergent containing case 6 has less rattling, and the detergent can be easily introduced.

Since the lower surface 7b of the flow path structure portion, the sliding surface 34 of the flow path structure portion 7, the claws 35 of the flow path structure portion 7, and the supporting means 38 of the flow path structure portion 7 are integrally configured, the flow path structure is formed. The claws 35 of the portion 7 and the supporting means 38 of the flow path structure portion 7 can be configured by one component, are less likely to be displaced, and reduce the rattling of the detergent accommodating case 6. Even if the gap between the support means 38 of 7 and the position restraining means 39 of the detergent containing case 6 is designed to be small, it is possible to prevent the sliding of the detergent containing case 6 from being hindered.

7, FIG. 8, FIG. 9 and FIG. 10, the first water supply means 48 supplies water to a position eccentric to the left side from the center of the washing tub 1, and the second water supply means 49 supplies the first water supply means 48. Since the water is supplied to the eccentric position on the right side, which is substantially symmetrical to, the shower water 50 can be uniformly impregnated into the entire laundry 55 even when the tap water pressure is low and the shower water 50 cannot be fanned out. The performance can be improved. Since the first water supply means 48 and the second water supply means 49 are arranged at the left and right ends of the lateral flow passage 41, and the water supply valve 18 and the flow passage structure portion 7 can be shared, the washing machine main body can be made compact. Can be designed.

In the first rotation state in which the laundry tub 1 rotates clockwise, the laundry 55 located on the left side of the laundry tub 1 moves toward the first water supply means 48 located on the left side of the laundry tub 1. The shower water 50 is urged toward the washing tub 1 by the first horizontal opening 46 (first urging means), that is, in a direction substantially opposite to the moving direction of the laundry 55. As shown in FIG. 9, the shower water 50 from the first water supply means 48 is applied to the laundry 55 while moving upward in order from the lower right in accordance with the movement of the laundry 55.

In the second rotation state in which the washing tub 1 rotates counterclockwise, as shown in FIG. 10, the second water supply means 49 moves upward from the opposite side of the laundry 55, from the lower left to the shower water. 50 is hung on the laundry 55. As a result, while the first rotating state and the second rotating state are repeated, the shower water 50 can be uniformly soaked in the entire laundry 55, and the washing performance can be improved.

In particular, when the rinse operation is performed after the dehydration operation, the laundry 55 is attached to the periphery of the laundry tub 1 due to the centrifugal force due to the high speed rotation of the laundry tub 1, so that the first horizontal By orienting the opening 46 and the second horizontal opening 47 in the circumferential direction of the washing tub 1, the shower water 50 can be uniformly impregnated into the entire laundry 55, and the washing performance can be improved.

As shown in FIG. 2, the first water supply means 48 and the second water supply means 49 are arranged adjacent to each other on the left and right sides of the detergent accommodating case 6, and the flow path structure portion 7 and the water supply valve 18 can be shared. The main body of the washing machine can be designed compact, and the washing time can be shortened by pouring the detergent solution 9 and the shower water into the washing tub 1 at the same time. Although it has been described that two water supply means are provided, the number of water supply means is not limited to two, and the same effect can be obtained by providing two or more water supply means.

In FIG. 11, the end opening 51 has a substantially circular opening and has an opening size larger than the vertical opening size of the first horizontal opening 46 and the second horizontal opening 47. The water flow becomes thick, and the water flow that is not easily affected by surface tension can be jetted radially from both ends, and the water from the first horizontal opening 46 and the second horizontal opening 47 is formed between the end openings 51. The shower water 50 can be easily fan-shaped even when the tap water pressure is low.

The opening area S1 including the first horizontal opening 46 and the left and right end openings 51 of the first horizontal opening 46 is set to be smaller than the flow passage cross-sectional area S2 of the first water pipe portion 43. Therefore, even if the tap water pressure is low, a constant water pressure according to the water level continues to be applied to the first horizontal opening 46, so that the shower water 50 can be stably ejected and the shower water 50 Can be easily fanned out.

Since the inner surface of the jaw 52 is formed by extending the part of the spherical surface portion 45 to the edge of the first horizontal opening 46 by the diaphragm surface 53, the water pressure is applied perpendicularly to the surface of the spherical surface portion 45. The shower water 50 is easily jetted straight from the horizontal opening 46, and the shower water 50 is easily spread in a fan shape. The outside of the jaw portion 52 has a receding surface 54 that recedes downward from the edge of the first horizontal opening portion 46 with respect to the extending direction of the first water pipe portion 43. Since one horizontal opening 46 can be molded and can be molded without adding a slide mechanism to the mold, it can be easily manufactured.

As described above, in the washing machine according to the present invention, the detergent can be efficiently dissolved by the mixing chamber and the crushing chamber even if the tap water pressure fluctuates, so that the cleaning performance is prevented from varying. It is useful as a washing machine and the like.
