Summary of the invention

Problems to be solved by the invention

The state of the water discharged from the discharge ports of the members of Patent Documents 1 to 3 is largely affected by the amount of water accumulated in the washing tub, the height of the water level, and the discharge port. For example, when the amount of water is small, or the water level is lower than the discharge port, and the height difference between the water level and the discharge port is large, the water potential at the time of discharge from the discharge port is weak, and the discharge range of water is narrowed. Thus, it is difficult to completely pour the water discharged from the discharge port to the laundry in the washing tub.

In Patent Document 1, since the discharge port is linearly wrapped so as to be flat along the tangential direction of the inner circumferential surface of the washing tub, the water discharged from the discharge port does not reach the inner peripheral surface of the washing tub. The circumferential direction spreads and only splashes onto the laundry on the side of the center of curvature of the inner peripheral surface of the washing tub.

In Patent Document 2, a portion around the discharge port in the guide wall portion is formed in a substantially arc shape that bulges toward the center of curvature of the inner circumferential surface of the washing tub. Similarly, in Patent Document 3, the portion around the discharge port in the water passage constituting member is also formed in a substantially arc shape that bulges toward the center of curvature of the inner circumferential surface of the washing tub. Therefore, since the discharge port is surrounded by a substantially arc shape that bulges toward the center of curvature of the inner circumferential surface of the washing tub, the water discharged from the discharge port faces the washing tank not only toward the center of curvature but also toward the washing tank. The inner circumferential surface of the inner circumferential surface is diffused into a fan shape, and all of it is poured onto the laundry.

However, in the case of

Patent Documents

2 and 3, it is difficult to form a portion around the discharge port of the guide wall portion and the water passage constituting member so as to bulge toward the center of curvature of the inner circumferential surface of the washing tub.

Since the present invention has been completed based on such a background, it is an object of the present invention to provide a component and a washing machine having the same, which is used for picking up water accumulated in a washing tub and pouring it onto the laundry in the washing tub. It also reduces the difficulty in setting the structure for pouring all of the water onto the laundry.

Further, an object of the present invention is to provide a member which can more completely pour water onto a laundry and a washing machine including the same.

Technical solution for solving the problem

The component of the present invention is applied to a vertical washing machine having a bottomed cylindrical washing tank having an inlet and outlet at a top end and a bottom wall at a lower end, comprising: a main body portion; a back surface facing the inner circumference of the washing tub and a surface on the opposite side of the back surface facing the center axis side of the washing tub, and being mounted in the washing tub in an up and down posture An inner peripheral surface; an intake port provided at a lower end portion of the main body portion for ingesting water in the washing tub from the bottom wall side; and a water passage provided in the main body portion for The water taken in by the intake port is guided upward; and a discharge port provided on a surface of the upper end portion of the main body portion for discharging water guided by the water passage and splashing from the upper portion into the washing tub In the laundry, the discharge port is long in the circumferential direction of the inner circumferential surface of the washing tub, and the upper and lower widths of the discharge port are two in the central portion in the circumferential direction than in the circumferential direction. The end is narrower, and the groove is adjacently disposed on the surface of the main body portion Both outer sides in the circumferential direction of said discharge port.

Further, the present invention is characterized in that the member is mounted on the inner peripheral surface of the washing tub in a state of being collected in plural and arranged in the circumferential direction, each of the members including: a guiding member, The guiding member is provided on the surface of the main body portion so as to wrap the upper end of the discharge port, and the water discharged from the discharge port is guided obliquely downward with respect to the horizontal direction.

Further, the present invention is characterized in that the member is mounted on the inner peripheral surface of the washing tub in a state of being collected in plural and arranged in the circumferential direction, each of the members including: an occluding member, The occluding member blocks one end of the same side in the circumferential direction at the discharge port.

Further, the present invention is a washing machine comprising the above-described members.

Effect of the invention

According to the present invention, a component of a vertical washing machine for a bottomed cylindrical washing tank having an inlet and outlet having a laundry formed at an upper end and a bottom wall at a lower end includes a main body portion to be mounted in an up and down posture The inner peripheral surface of the washing tank. In the main body portion, the water in the washing tub can be taken in from the intake port of the lower end portion, guided upward by the water passage, discharged from the discharge port on the surface of the upper end portion of the main body portion, and poured into the washing tub from above. Washed on.

The discharge port is long in the circumferential direction of the inner circumferential surface of the washing tub. It is difficult for the discharge port which is long in the circumferential direction to spread the water rising from the water passage to the discharge port to both ends in the circumferential direction. However, the width of the upper and lower sides of the discharge port is narrower at the central portion in the circumferential direction than at both ends in the circumferential direction. That is, the discharge port is wide from the central portion in the circumferential direction to both ends. Therefore, even if the water potential from the water passage toward the discharge port is weak, since the water rising to the discharge port spreads over the entire area from the center portion to the both ends in the discharge port, the discharge port can discharge the water from the entire area in the circumferential direction.

Further, on the surface of the main body portion, grooves are provided adjacent to each other on both outer sides of the discharge port in the circumferential direction. In other words, it is only necessary to provide a groove on both outer sides of the discharge port on the surface of the main body portion, and the discharge port is surrounded by a substantially arc shape which is bulged toward the central axis of the washing tub, so that the row is arranged. The water discharged from the outlet diffuses into a fan shape not only toward the central axis side but also in the circumferential direction of the inner peripheral surface of the washing tub, and all of it is poured onto the laundry. Therefore, it is possible to reduce the difficulty in providing a discharge port which is provided in a substantially arc shape as a structure for pouring all of the water onto the laundry.

Further, according to the present invention, in the case where the members are mounted on the inner peripheral surface of the washing tub in a state of being collectively arranged in a plurality of rows and arranged in the circumferential direction, in each of the members, the discharge port is formed on the surface of the main body portion. The guide member provided at the upper end by the edging method guides the water discharged from the discharge port obliquely downward with respect to the horizontal direction. Therefore, even if water discharged from each of the discharge ports of the plurality of members collides with each other in the washing tub, compared with the case where water is discharged from the respective discharge ports in the horizontal direction or obliquely upward with respect to the horizontal direction, a collision wall in which the water collides with each other from the entrance and exit to the bottom wall in the washing tank side. Therefore, it is possible to prevent the water after the collision from scattering to the outside of the entrance and exit, and to more completely pour the water onto the laundry on the side of the bottom wall.

Further, according to the present invention, in the case where the components are mounted on the inner circumferential surface of the washing tub in a state of being collectively arranged in a plurality of rows and arranged in the circumferential direction, in the respective members, the discharge port is blocked in the circumferential direction by the blocking member. One end on the same side. Thus, by preventing the water discharged from each of the discharge ports of the plurality of members from colliding with each other as much as possible, it is possible to prevent the water after the collision from scattering to the outside of the entrance and exit, and to more completely splash the water onto the laundry.

Further, according to the present invention, in the washing machine including the above-described members, it is possible to reduce the difficulty in providing a structure for pouring all of the water onto the laundry in the member.

In the water tank 4, water such as tap water, bath water, and a liquid in which the detergent is dissolved is accumulated.

The washing tub 5 is formed into a bottomed cylindrical shape which is one turn smaller than the water tub 4. The washing tub 5 has a substantially cylindrical peripheral wall 5B having an inlet and outlet 5A at the upper end, and a disk-shaped bottom wall 5C that blocks the hollow portion of the circumferential wall 5B from the lower side X2. Therefore, in the washing tub 5, the inlet 5A is formed at the upper end, and the bottom wall 5C is provided at the lower end. The washing tub 5 is housed in the water tank 4 in a coaxial state. The washing tub 5 in a state of being housed in the water tank 4 is rotatable about a central axis 9 extending in the vertical direction X and orthogonal to the horizontal direction H. Therefore, the washing machine 2 is a vertical washing machine in which the washing tub 5 is vertically arranged.

The entrance 5A communicates with the opening 4A from the lower side X2, and the opening 4A and the entrance 5A are opened and closed by the cover 8. The user of the washing machine 2 can input and take out the laundry S into the washing tub 5 via the opened port 5A. The through hole 5D is formed in the bottom wall 5C, and the water in the water tank 4 reciprocates between the water tank 4 and the washing tub 5 via the through hole 5D.

The annular balancer 10 is attached to the upper end portion of the inner peripheral surface 5E of the circumferential wall 5B. The balancer 10 is a member that reduces the vibration of the washing tub 5 during rotation, and a liquid for facilitating vibration reduction is accommodated in the cavity 10A inside the balancer 10.

The motor 6 is disposed below the bottom wall 4C of the water tank 4 in the casing 3 by X2. The output shaft 6A of the motor 6 extends upward X1, and penetrates in the order of the center of the bottom wall 4C and the center of the bottom wall 5C of the washing tub 5. The output shaft 6A has a flange portion 6B that protrudes in a ring shape between the bottom wall 4C and the bottom wall 5C, and the flange portion 6B is coupled to the washing tub 5 by being fixed to the bottom wall 5C. The washing tub 5 is rotated when the motor 6 is driven.

The rotary wing 11 is attached to the upper end portion of the output shaft 6A that protrudes upward from the bottom wall 5C by X1. The rotary wing 11 is a so-called pulsator. The rotary wing 11 is formed in a disk shape, and an upper end portion of the output shaft 6A is attached to the center of the rotor. A plurality of agitating blades 11A arranged in a radial shape are provided on the upper surface of the rotor blade 11, and a plurality of pump blades 11B arranged in a radial shape are provided on the lower surface of the rotor blade 11. When the motor 6 is driven, the rotary wing 11 rotates, and the laundry S in the washing tub 5 is stirred by the stirring blade 11A.

The member 1 is mounted on the inner circumferential surface 5E of the washing tub 5. Hereinafter, the circumferential direction of the inner circumferential surface 5E is referred to as a circumferential direction Y, and the radial direction of the inner circumferential surface 5E is referred to as a radial direction Z. In the radial direction Z, the side toward the central axis 9 is referred to as the radially inner side Z1, and the side away from the central axis 9 is referred to as the radially outer side Z2. The vertical direction X and the circumferential direction Y are orthogonal to each other when viewed from either the radially inner side Z1 and the radially outer side Z2.

The number of components 1 used in the washing machine 2 can be arbitrarily set, either single or plural. In this embodiment, the member 1 is attached to the inner circumferential surface 5E in a state in which a plurality of members having the same shape and the same size are arranged in the circumferential direction Y. The spacing of the adjacent members 1 in the circumferential direction Y may be fixed between any of the members 1 or different depending on the member 1.

The member 1 includes a main body portion 12 made of resin. The main body portion 12 has a long lid shape in the up-and-down direction X, and is disposed between the balancer 10 and the bottom wall 5C of the washing tub 5 and is attached to the washing tub 5 from the radially inner side Z1 in the vertical posture. On the 5E surface. Therefore, the main body portion 12 has a rear surface 12A that faces the inner circumferential surface 5E of the washing tub 5 and a surface 12B that faces the side opposite to the rear surface 12A and faces the center shaft 9 side.

An intake opening 13 is provided in the lower end portion 12C of the main body portion 12, and a discharge port 14 is provided on the surface 12B of the upper end portion 12D of the main body portion 12. A water passage 15 extending in the vertical direction X is provided on the back surface 12A of the main body portion 12. The water passage 15 is blocked from the radially outer side Z2 by the inner peripheral surface 5E of the washing tub 5, communicates with the intake port 13 at the lower end, and communicates with the discharge port 14 at the upper end.

When the rotary wing 11 rotates, the water in the washing tub 5 is pressed into the intake opening 13 of each member 1 through the pump blade 11B of the rotary wing 11, and is taken up from the bottom wall 5C side of the washing tub 5 to Ingestion mouth 13. The water taken in by the intake port 13 is guided to the discharge port 14 of the upper X1 through the water passage 15, and then discharged from the discharge port 14, and the laundry S splashed from the upper side X1 into the washing tub 5 as indicated by a thick broken arrow. on. Thereby, since the water in the washing tank 5 is repeatedly used for washing by circulating through the water passage 15 of the member 1, it is possible to wash with a small amount of water.

Next, the component 1 will be described in detail.

Two components 1 are illustrated in FIG. Among the two members 1, a front view when viewed from the radially inner side Z1 is illustrated as one member 1, and a longitudinal cross-sectional view is shown as the other member 1. As shown in the one member 1, in each of the members 1, the discharge port 14 is a slit which is long in the circumferential direction Y of the inner circumferential surface 5E of the washing tub 5. Hereinafter, the posture of the member 1 when attached to the inner circumferential surface 5E of the washing tub 5 As a reference, in this case, the direction is mainly determined by the vertical direction X, the circumferential direction Y, and the radial direction Z.

Fig. 3 is a perspective view of the member 1 as seen from the front.

Referring to Fig. 3, in the main body portion 12 of the member 1, a portion above the lower end portion 12C by X1 extends upward in the circumferential direction Y by substantially the same width, and the lower end portion 12C is in the circumferential direction Y toward the lower side X2. Slowly widen on the top.

In Figure 3, the surface 12B of the body portion 12 is maximized and illustrated. In the main body portion 12 of Fig. 3, the surface located behind the surface 12B is the back surface 12A. The radially inner side Z1 is a front side of the main body portion 12 from the back surface 12A toward the front surface 12B, and the radially outer side Z2 is a back side of the main body portion 12 from the front surface 12B toward the back surface 12A.

The surface 12B may be a flat surface or a curved surface, or may be a surface in which a flat surface and a curved surface are combined. The outer peripheral portion of the surface 12B when viewed from the radially inner side Z1 constitutes a flange 16 which is bent from the surface 12B and extends radially outward Z2 except for substantially the entire lower end portion.

Figure 4 is a rear elevational view of the component 1.

As shown in FIG. 4, the overall shape of the flange 16 when viewed from the back side of the member 1, that is, the radially outer side Z2, is formed in a substantially U shape which is upside down. Among the flanges 16, the upper flange 16A at the upper end of the main body portion 12 extends flat in the circumferential direction Y.

In the upper flange 16A, the central portion in the circumferential direction Y constitutes a block-shaped first engaging portion 17 that protrudes upward from the upper side X1. In the main body portion 12, the plug-shaped second engaging portions 18 projecting downward from the lower end X2 are formed in a pair in the circumferential direction Y at intervals. As described above, in a state where the main body portion 12 is placed between the balancer 10 and the bottom wall 5C of the washing tub 5, the first engaging portion 17 is engaged with the balancer 10 from the lower side X2, and the second engaging portion 18 is engaged. The upper portion X1 is engaged with the bottom wall 5C, so that the main body portion 12 is positioned on the balancer 10 and the bottom wall 5C, respectively.

On the back surface 12A of the main body portion 12, a pair of ribs 19 extending in the vertical direction X are integrally provided in a region inside the substantially U-shaped flange 16. The upper end portions 19A of the pair of ribs 19 are bent and coupled in a direction in which they approach each other, and extend as a whole in the circumferential direction Y. Therefore, the overall shape of the pair of ribs 19 is smaller than the overall shape of the flange 16, and is formed in a substantially U-shape that is upside down. The space enclosed by the pair of ribs 19 is the water passage 15. Strictly speaking, the water passage 15 is a vertically long space defined by the pair of ribs 19, the back surface 12A of the main body portion 12, and the region facing the back surface 12A of the main body portion 12 in the inner peripheral surface 5E of the washing tub 5. .

The lower end portions 19B of the pair of ribs 19 extend obliquely so as to gradually expand toward the lower side X2 with respect to each other in the circumferential direction Y. The intake port 13 is a region sandwiched by the lower end portion 19B of the pair of ribs 19, and is opened toward the lower side X2. The discharge port 14 is located at the upper end of the water passage 15, and is adjacent to the upper end portion 19A of the pair of ribs 19 from the lower side X2, and penetrates the main body portion 12 in the radial direction Z.

Each of the pair of ribs 19 does not need to extend linearly in the vertical direction X, and may be curved in the middle. Depending on the shape of the rib 19, the width of the water passage 15 in the circumferential direction Y may be changed in the middle of the vertical direction X.

On the back surface 12A, a tubular boss 20 that protrudes toward the radially outer side Z2 is integrally provided at a position avoiding the water passage 15. The number of the bosses 20 can be arbitrarily set. In this embodiment, the bosses 20 are arranged vertically and horizontally at a substantially central portion of each of the pair of ribs 19 in the vertical direction X. A plug (not shown) provided on the inner peripheral surface 5E of the washing tub 5 is inserted into each of the bosses 20, whereby the member 1 is positioned in the washing tub 5.

Figure 5 is a front view of the component 1. Fig. 6 is a cross-sectional view taken along line VI-VI of Fig. 5; Fig. 7 is a cross-sectional view taken along line VII-VII of Fig. 5;

Referring to Fig. 5, with respect to the upper and lower widths W of the discharge port 14, when the width of the central portion 14A in the circumferential direction Y is referred to as the width W1, and the width of the both ends 14B in the circumferential direction is referred to as the width W2, the width W1 is The width W2 is narrow, and the width W is formed to gradually narrow from the both ends 14B toward the central portion 14A. That is, the upper and lower widths W of the discharge port 14 are narrower than the both ends 14B at the center portion 14A.

In the discharge port 14 which is only long in the circumferential direction Y, it is difficult for the water rising from the water path 15 to the discharge port 14 to spread over both ends 14B in the circumferential direction Y. However, in the member 1 of the present embodiment, since the vertical width W of the discharge port 14 is narrower than the both ends 14B in the central portion 14A, the discharge port 14 is widened from the central portion 14A toward both ends 14B. Therefore, even if the water potential from the water passage 15 toward the discharge port 14 is weak, since the water rising to the discharge port 14 extends from the central portion 14A to the entire end of the both ends 14B at the discharge port 14, the water can be discharged from the circumferential direction at the discharge port 14 The entire area of Y is discharged in a wide range.

Referring to Fig. 6, the grooves 21 are provided adjacent to both sides of the discharge port 14 in the circumferential direction Y one by one on the surface 12B of the upper end portion 12D of the main body portion 12. Each of the grooves 21 is formed in the upper end portion 12D of the main body portion 12 so as to be recessed toward the back surface 12A side of the main body portion 12, and extends in the vertical direction X (see also FIG. 3). Thereby, in the main body portion 12, the surface 12B of the upper end portion 12D is pressed toward the inner side in the circumferential direction Y, and the discharge port 14 is surrounded by a substantially arc shape that bulges toward the radially inner side Z1. Therefore, the discharge port 14 faces the radially inner side Z1, and is also opened at both ends 14B in such a manner as to face the circumferential direction Y.

In this case, the water discharged from the discharge port 14 is diffused in the fan-shaped discharge range P which is expanded from the discharge port 14 to the radially inner side Z1 in plan view as indicated by a broken line in FIG. 6 .

In the present embodiment, it is only necessary to provide the groove 21 on both the outer sides of the discharge port 14 on the surface 12B of the main body portion 12, and the discharge port 14 can be wrapped to the side of the central axis 9 of the washing tub 5, that is, the radial direction. The inner side Z1 bulges in a substantially arc shape. Therefore, even if the water discharged from the discharge port 14 has a small flow rate, it is expanded to the discharge range P of the sector in a wide range not only toward the radially inner side Z1 but also toward the circumferential direction Y, and all of them are splashed. Go to the laundry S. Therefore, in the washing machine 2, as a structure for pouring all of the water onto the laundry S, it is possible to reduce the difficulty in providing the discharge port 14 which is surrounded by the substantially arc shape.

As the order in which the grooves 21 are provided on the main body portion 12, when the main body portion 12 is formed by injection molding or the like, the concave portion 21 and the main body portion may be provided by previously providing a convex portion corresponding to the concave portion 21 in the mold. 12 is formed into one. Further, the groove 21 may be later placed in the formed body portion 12 by cutting or the like.

Referring to FIG. 7, the rib 22 and the guiding member 23 are disposed around the discharge port 14 in the surface 12B of the main body portion 12. The rib 22 extends in the circumferential direction Y along the discharge port 14 so as to wrap the lower end of the discharge port 14, and protrudes in the horizontal direction H toward the radially inner side Z1. The rib 22 may protrude slightly obliquely upward with respect to the horizontal direction H1. The guide member 23 extends in the circumferential direction Y along the discharge port 14 on the surface 12B of the main body portion 12 so as to hem the upper end of the discharge port 14, and is inclined toward the lower side X2 with respect to the horizontal direction H toward the radially inner side Z1. protruding. A direction in which the guiding member 23 protrudes obliquely downward to the lower side X2 is referred to as an obliquely lower side X3.

The rib 22 and the guiding member 23 extend in parallel in the circumferential direction Y, and since the both end portions in the circumferential direction Y are not connected, the both ends 14B of the discharge port 14 are maintained in a state facing the circumferential direction Y (refer to FIG. 5 and Figure 6). The interval between the rib 22 in the up and down direction X and the guiding member 23 is the width W of the discharge port 14 described above.

The water discharged from the discharge port 14 is guided by the rib 22 so as not to fall along the surface 12B of the main body portion 12, and flows to the radially inner side Z1. The guiding member 23 protrudes more radially inward than the rib 22 from the rib 22 . Therefore, the water discharged from the discharge port 14 and flowing to the radially inner side Z1 is guided to the obliquely lower side X3 with respect to the horizontal direction H by the guiding member 23.

Therefore, even if the water discharged from the respective discharge ports 14 of the plurality of members 1 collide with each other in the washing tub 5, the water collides with each other from the respective discharge ports 14 in the horizontal direction H or obliquely upward with respect to the horizontal direction H. In contrast, in the washing tank 5, the collision position of the water can be moved from the inlet and outlet 5A to the lower side of the bottom wall 5C (see the thick dotted arrow in Fig. 2). Therefore, it is possible to prevent the water after the collision from scattering to the outside of the entrance and exit 5A, and to completely splash the water onto the laundry S on the side of the bottom wall 5C.

The member 1 according to the modification is assumed to be a plurality of pieces as described above. Each of the members 1 is entirely black as shown in Fig. 8, and includes a blocking member 24 that closes one end portion on the same side in the circumferential direction Y in the discharge port 14. The blocking member 24 is formed in a block shape spanned between the rib 22 and the guiding member 23, and may be integrally formed with the main body portion 12 or may be attached to the main body portion 12 later. When the respective members 1 are viewed from the radially inner side Z1, in any one of the members 1, the blocking member 24 is provided only at one end portion (the left end portion in FIG. 8) in the circumferential direction Y in the discharge port 14, and the One end is blocked. Thus, in any of the members 1, only one of the both ends 14B of the discharge port 14 faces the circumferential direction Y, and the other end of the both ends 14B in which the closing member 24 is provided does not face the circumferential direction Y.

As shown in FIG. 9, when the member 1 according to the modification is used, in each of the members 1, the discharge range P in the plan view of the water discharged from the discharge port 14 is only a dotted line as compared with the case where the blocking member 24 is not present. The shaded area Q is narrowed. That is, the water discharged from the discharge port 14 is blocked by the occluding member 24, and the discharge direction is restricted so as not to diffuse toward the region Q. Therefore, by preventing the water discharged from the respective discharge ports 14 of the plurality of members 1 from colliding with each other as much as possible, it is possible to prevent the water after the collision from scattering to the outside of the inlet and outlet 5A, and to more completely splash the water onto the laundry S. .

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention.

For example, the main body portion 12 of the member 1 has a lid shape, and the water passage 15 is a space defined by the back surface 12A of the main body portion 12, the pair of ribs 19 of the back surface 12A, and the inner circumferential surface 5E of the washing tub 5. Alternatively, the main body portion 12 may be a hollow body, and the water passage 15 may be built into the main body portion 12 by changing the hollow portion into the water passage 15.
