Description

washing machine

field of invention

In general, the present invention relates to a washing machine, and more particularly to a tub-type washing machine with an ascending water flow guide and a spin-drying shaft bracket. damage, and the spin spin shaft bracket fits easily onto the spin bucket.

Background technique

It is clear to those skilled in the art that a washing machine performs laundry by rotating a drum filled with laundry and washing water. Such washing machines are typically classified into drum type washing machines and vertical axis type washing machines. The design of the front-loading washing machine is that the rotating tub is placed horizontally in the cabinet, rotates in opposite directions around the horizontal axis of the cabinet, repeatedly moves the clothes placed on the inner surface of the washing tub up and down and allows the clothes to fall from top to bottom in the tub due to gravity , so as to achieve the purpose of laundry. In the vertical axis washing machine, the rotating tub with the agitator is placed vertically in the cabinet and rotates in opposite directions around the vertical axis of the cabinet, so that the clothes in the tub can be cleaned by the forced water flow generated by the agitator.

The present invention relates to such a vertical axis washing machine. FIG. 1 shows the construction of a conventional vertical axis washing machine. As shown in the figure, a conventional vertical axis washing machine includes a cabinet 1 constituting the outer shape of the washing machine. The tubs are placed in the cabinet, that is, the washing tub 2 is vertically placed in the cabinet 1, and the tub is filled with washing water, while the dehydration tub 3, the so-called "drum" is placed in the main laundry tub 2, which can rotate and be connected with the washing machine. Barrel concentric. The side wall of the dehydration barrel 3 has many dehydration holes 3c. The agitator 4 is installed at the bottom of the dehydration tub 3 and generates a washing water flow in the washing tub 3 . The washing machine also has a driving motor 5 and a power transmission unit 6 installed in the space between the bottom of the washing tub 2 and the bottom of the cabinet. The drive motor 5 is a reversible motor that generates reversible power, and the power transmission unit 6 transmits the rotational force from the motor to the bucket device, thereby rotating the dehydration bucket 3 and the agitator 4 .

The top of the cabinet 1 is openable, so that the user can put clothes into the dehydration bucket 3 and take out the clothes therefrom, and the door 7 is hinged to the open side of the cabinet 1, so that the user can open or close the cabinet 1 exposure. The drain pipe 8 extends from the bottom of the washing tub 2 to the outside of the cabinet 1, and drains water from the tub 2 to the outside of the cabinet 1 after the washing operation is finished.

The dehydration tub 3 includes a bottom 3a and a cylindrical body 3b. The bottom 3a has an opening in its center. The dehydration shaft 6a of the power transmission unit 6 cooperates with the bottom of the dehydration bucket 3 at the opening, and the washing shaft 6b cooperates with the agitator 4 after passing through the opening. The bottom edge of the cylindrical body 3b and the outer side of the bottom 3a are combined with many fixing screws to form a monolithic structure.

The ascending water flow guide 10 is fitted on the inner surface of the cylindrical body 3b of the dehydration tub 3 . The guide 10 guides the washing water flow generated by the reversible rotation of the agitator 4 in the laundry mode to move toward the top of the dehydration tub 3, and discharges the water from the top to the clothes in the tub 3, thereby more effectively dissolving the detergent in the water , and apply hydraulic pressure and mechanical impact to the clothes, thus improving the washing effect of the washing machine. A burlap bag 11 is provided on top of the water flow guide 10 for collecting debris such as lint in the water drained from the water guide 10 .

Fig. 2 is a perspective view showing the assembly structure of the conventional dehydration shaft support and the bottom of the dehydration bucket.

As shown in the figure, the dehydration shaft support 15 is assembled on the bottom 3a of the dehydration bucket 3, and the dehydration shaft 6a of the power transmission unit 6 is assembled on the bottom 3a. The shaft support 15 includes a hub 16 having a socket 16a for receiving the top of the dehydration shaft 6a. A plurality of outriggers 17 extend radially outward from the hub 16, and each outrigger 17 has a locking hole 17a on its outer side. The socket 16a of the hub 16 has a rectangular cross-section and is in close contact with the top of the dehydration shaft 6a so as to be rotatable with the dehydration shaft 6a. The bottom 3a of the dehydration bucket 3 is assembled with the shaft support 15, and has an opening 18 in its center. The washing shaft 6b extends axially upward from the inside of the dehydration shaft 6a, and cooperates with the agitator 4 inside the dehydration bucket 3 after passing through the opening 18 of the bottom 3a. The openings 18 simultaneously allow wash water to drain from the spin tub 3 to the bottom of the wash tub 12 during the dehydration process. The portion of the bottom 3a around the opening 18 is flat, and there are many lock holes 19 at positions corresponding to the lock holes 17a on the extension arm 17 on the shaft support 15 . Therefore, the shaft support 15 can be fixed to the bottom 3a by using a plurality of set screws 20 at the locking holes 17a and 19 .

Figures 3a and 3b are partial cross-sectional perspective views showing a conventional ascending water flow guide and dewatering tub assembly. Among the figures, Fig. 3a shows the water flow guide separated from the dehydration bucket, and Fig. 3b shows the water flow guide completely assembled with the dehydration bucket.

As shown in Fig. 3a, the longitudinal water flow guide 10 is shown separately from the dehydration bucket 3, and is axially assembled on the inner surface of the side wall of the bucket body 3b of the dehydration bucket. As mentioned above, the guide 10 guides the washing water generated by the agitator 4 to move toward the top of the spin-drying tub 3 during the washing process. The above-mentioned longitudinal guide 10 is open at the top, bottom and rear, thus having a U-shaped cross-section and forming a longitudinal passage. On the guide 10, there are regularly formed many internal threaded holes (not shown) at positions corresponding to the screw holes 3d on the side wall of the dehydration bucket body 3b, so the guide 10 can be fixed to the dehydration bucket 3 with a plurality of fixing screws 20 on the barrel body 3b.

When the water flow guide 10 is fully assembled on the inner surface of the dehydration barrel body 3b as shown in FIG. A water outlet 22 is formed between the side wall of the dehydration barrel body 3 b and the top end of the guide 10 to discharge water from the guide 10 .

The operation of the vertical axis washing machine with the dehydration tub 3 and the water flow guide 10 at the same time is as follows. The clothes are put into the dehydration tub 3, the washing machine is switched on, and a predetermined amount of water is injected into the washing tub 2 at first. Thereafter, the reversible motor 5 rotates to generate a rotational force and is transmitted to the agitator 4 through the power transmission unit 6, thereby rotating the agitator 4 in the opposite direction. The reversible rotation of the agitator 4 generates a washing water flow in the dehydration bucket 3, so that the clothes are forced to move with the water flow, and at the same time form frictional contact with the inner surface of the dehydration bucket 3 and other clothes to achieve the purpose of washing. In this case, part of the washing water flow generated by the agitator 4 is introduced into the water flow guide 10 through the water inlet 21, rises along the guide 10, and is discharged from the guide 10 to the clothes through the water outlet 22, thereby improving the washing machine. washing effect. When the water is discharged from the guide 10 through the water outlet 22 , various impurities in the water, such as lint, are captured by the burlap bag 11 and collected in the burlap bag 11 .

In a conventional vertical axis washing machine, the bottom 3a of the dehydration tub 3 and the dehydration shaft support 15 are connected together by many fixing screws, and the step of tightening the screws complicates the assembly process. In addition, when the washing machine is repeatedly used for a long time, the screws of the dehydration bucket 3 will definitely loosen, thereby generating vibration during the dehydration process.

The bottom 3a of the conventional dehydration tub 3 is flat and therefore does not have the desired high structural strength.

The ascending water flow guide 10 is fixed on the barrel body 3b of the dehydration barrel 3 with many screws. Therefore, the guide 10 is not in close contact with the inner surface of the dehydration tub 3, but a gap is formed at the junction of the dehydration tub 3 and the guide. Thus the wash water seeps from the guide 10 into the inside of the spin-drying tub 3 through the gap of the joint, so the guide 10 cannot guide a sufficient amount of water to its water outlet 22 . Since the amount of water discharged from the water outlet 22 of the guide 10 to the clothes in the dehydration tub is insufficient, the washing effect of the washing machine is weakened. In addition, it is almost impossible to effectively remove foreign substances, such as lint, from the water with the burlap bag 11, which impairs the washing effect of the washing machine.

The bottom 3 a of the dehydration bucket 3 has an upward annular flange 23 aligned with the bottom edge of the water flow guide 10 . Sundries may be stored inside the flange 23 , and the clothes are in frictional contact with the flange 23 during the operation of the washing machine, and are easily damaged by the flange 23 .

Another problem with the conventional vertical axis washing machine is that the material of the guide 10 is different from that of the drum body 3b of the dehydration tub 3 . Due to the different materials of the dehydration tub body 3b and the guide 10, when the washing tub 2 is filled with hot water for laundry operation, the guide 10 will be thermally deformed due to the different thermal expansion coefficients of the dehydration tub body 3b and the guide 10 . This thermal deformation of the guide expands the gap between the barrel body 3b and the guide, so that foreign matter is stored in the gap, thereby polluting the clothes after washing. Clothes may be blocked in the large gap between the dehydration tub body 3b and the guide 10 and be damaged.

Moreover, the material of the dehydration shaft support 15 is different from that of the bottom 3 a of the dehydration bucket 3 , therefore, the bottom 3 a and the support 15 may be corroded due to the potential difference caused by the different materials. The corroded bottom 3a or the corroded rack 15 may contaminate the laundry during washing.

Detailed ways

Referring now to the drawings, in the following description, the conventional washing machine shown in FIG. 1 and the washing machine of the present invention have the same parts, which have the same reference numerals.

In a preferred embodiment of the present invention, Fig. 4 is a structural sectional view of a dehydration tub in a vertical axis washing machine. As shown, the dehydration bucket 30 includes a bottom 40 and a cylindrical bucket 50 . The central area of the bottom 40 has a hole. The dehydration shaft 6a is coupled with the dehydration tub 30 at the hole and rotates the tub 30 in the opposite direction, while the laundry shaft 6b passes through the hole before being coupled to the agitator 4 to rotate the agitator 4 in the opposite direction. The cylindrical body 50 is connected at its bottom to the outside of the bottom portion 40, while the dehydration tub 30 is cylindrical with an open top.

The connection between the outer edge of the bottom 40 and the bottom edge of the cylindrical barrel 50 can be realized by seaming. Wherein, the edges of the two parts 40 and 50 are connected at the seam 31 to form a single structure. Unlike the screw seams of conventional dehydration buckets, the seams 31 of the dehydration bucket 30 will not loosen even if the bucket 30 is repeatedly used for a long time.

A plurality of dehydration holes 51 are formed on the side wall of the cylindrical body 50 of the dehydration tub 30, through which water removed from the laundry by centrifugal action can be discharged from the dehydration tub 30 to the washing tub during the dehydration operation. The rising water flow guide 80 is installed on the inner surface of the staving 50, and a burlap bag 11 is arranged at the upper end of the water flow guide 80. The above-mentioned water flow guide 80 guides the washing water flow to the upper part of the dehydration tub 30. During the laundry mode, the washing water flow can be generated by the reverse rotation of the agitator 4, and then the upper part of the water is discharged to the clothes in the dehydration tub 30. In this way, the detergent in the water can be dissolved more effectively and the water force can be applied to the laundry, so the washing effect of the washing machine can be improved. The burlap bag 11 collects impurities such as lint from the wash water discharged from the water flow guider 80 .

That is to say, from the bottom to the upper part of the barrel body 50 , the water flow guide 80 is vertically installed on the inner surface of the barrel body 50 to guide the water generated by the agitator 4 to the upper part of the dehydration barrel 30 . The burlap bag 11 is attached to the upper end of the water flow guide 80, and collects impurities such as lint from the washing water discharged from the water flow guide 80.

In the present invention, it should be understood that in the area of the burlap bag attached to the top of the water flow guide, an additional ascending water flow guide can be installed on the inner surface of the barrel, providing a metal mesh at the opening of the additional guide , used to remove impurities from the wash water.

In the preferred embodiment shown in FIG. 4 , an ascending water deflector 80 is attached to the dehydration tub 30 . However, it should be understood that two or more water flow directors may be mounted on the inner surface of tub 30 at regular intervals if desired.

Fig. 5 shows a structural plan view of the bottom of the dehydration bucket. Fig. 6 shows a cross-sectional view of the dehydration shaft support installed on the bottom of the dehydration bucket according to the present invention.

As shown in the figure, the bottom 40 of the spin-drying tub 30 includes a central portion 41 , and a locking unit 43 is combined at the center of the central portion 41 . The locking unit 43 locks the dehydration shaft support 60 on the bottom 40 . Of course, the above-mentioned shaft support 60 supports the dehydration support 6 a at the bottom 40 of the dehydration tub 30 . The stepped portion 42 protrudes upward and outward from the outer edge of the central portion 41 as a whole.

There are a plurality of drainage holes 44 on a central portion 41 of the tub bottom 40 outside the lock unit 43 to discharge wash water from the dehydration tub 30 into the wash tub 2 during the dehydration operation (see FIG. 1 ). Along the annular area outside the drainage hole 44 , the central portion 41 is repeatedly depressed and convexed, so that the reinforced portion 45 is formed to increase the structural strength of the bottom 40 . Due to the reinforcing portion 45, the bottom 40 of the dehydration tub 30 can effectively withstand the dynamic load applied thereto by the wash water and the laundry during the rotation of the agitator 4 or the dehydration tub 30.

There is a water inlet 46 and a water outlet 47 on the bottom 40 of the dehydration bucket 30, and the water inlet 46 and the water outlet 47 can guide the washing water flow generated by the rotation of the agitator 4 to the inlet of the upward water flow guide 80. There is a water inlet 46 on the bottom 40 between the inner edge of the stepped portion and the outer edge of the central portion 41 , and a water outlet 47 on the upper portion of the stepped portion 42 .

The dehydration shaft bracket 60 can be locked on the locking unit 43 combined with the central part 41 of the bottom 40 . Referring to FIG. 6 , the structures of the dehydration shaft support 60 and the locking unit 43 will be described in detail below.

As shown in FIG. 6, the dehydration shaft support 60 of the present invention is a hollow cylinder, and inside the support 60 there is a shaft insertion hole 61 for accommodating the dehydration shaft 6a. At the lower end of the shaft holder 60 there is a hook-shaped recess 62 having a diameter larger than that of the shaft insertion hole 61 and mounted with the locking unit 43 . As shown in FIG. 5, the shaft insertion hole 61 of the shaft support 60 is square, and just accommodates the dehydration shaft 6a, so that it can rotate together with the dehydration shaft 6a. In this way, the dehydration tub 30 can rotate under the effect of the rotational force of the dehydration shaft 6a. Of course, it should be understood that the shaft insertion hole 61 may have another polygonal cross section in the area of the square cross section. The dewatering creel 60 may also have a cylindrical appearance.

The locking unit 43 is combined with the central part of the tub bottom part 40 and locks the dehydration shaft support 60 on the bottom part 40, and includes a cylindrical support wall 43a, a hook part 43b and a plurality of stuffing protrusions 43c. The support wall 43a protrudes vertically downward by a predetermined length from the central area of the central portion 41, and accommodates the dehydration shaft holder 60 therein. At the lower end of the support wall 43a, there is a hook portion 43b which engages with the lower end of the dehydration shaft holder 60. As shown in FIG. The stuffing protrusion 43c protrudes horizontally inwardly by a predetermined length in the radial direction from the top edge of the supporting wall 43a.

The locking unit 43 is assembled with the dehydration shaft support 60 as follows: that is, the hollow cylindrical shaft support 60 is fitted upwardly with the locking unit 43 from the lower end of the unit 43 . In this case, the hook portion 43b of the locking unit 43 is not at the lower end of the support wall 43a, but the lower end of the support wall 43a that will become the hook portion in the next step protrudes vertically, so that the shaft bracket 60 is aligned with the unit 43 Cooperate. As described above, when the shaft bracket 60 is fitted with the lock unit 43, the top end of the shaft bracket 60 is stuffed by the stuffing protrusion 43c of the lock unit 43, so the upward movement of the shaft bracket 60 inside the lock unit 43 is restricted. The outer surface of the shaft bracket 60 is surrounded by the support wall 43 a of the locking unit 43 .

Accordingly, the lower end of the supporting wall 43a is bent inwardly to form a hook-shaped portion 43b which engages with a hook-shaped recessed portion 62 formed at the shaft bracket 60 as shown in FIG. 6 . The dehydration shaft 6a is inserted into the shaft insertion hole 61 of the shaft holder 60 so that the shaft 6a can rotate the dehydration tub 30 .

As described above, the structure of the small-sized dehydration shaft support 60 does not require fixing screws when it is mounted on the bottom 40 of the dehydration tub 30 . The shaft bracket 60 is thus simply and easily mounted to the locking unit 43 provided on the bottom 40 of the dehydration tub 30 .

The undersized shaft support 60 and the bottom 40 of the dewatering bucket 30 are preferably made of the same material, such as corrosion-resistant stainless steel. In this way, the shaft support 60 can prevent corrosion caused by the voltage difference between the shaft support 60 and the dehydration tub 30 .

On the outside of the bottom 40 of the dehydration bucket 30, there is a cover 70 to cover the opening. The opening is located on the bottom part 40. The water inlet 46 and the water outlet 47 on the bottom 40 are used to guide the washing water to the upward flow guide. At the entrance of the device 80. The installation structure of the cover 70 installed on the dehydration tub 30 will be described in detail below with reference to FIG. 8 .

7a and 7b are partial cutaway perspective views of the mounting structure of the dehydration tub and the ascending water flow guide shown in FIG. 4 . In the drawings, Fig. 7a shows the water flow guide separated from the dehydration tub, and Fig. 7b shows the water flow guide installed together with the dehydration tub.

As shown in FIG. 7 a , the water flow guide 80 includes a longitudinal front wall 81 , and two side walls 82 protrude rearwardly from opposite sides of the front wall 81 to form a predetermined width. The water flow guide 80 is open at the top, bottom and rear.

There is a hook 83 at the lower end of the front wall 81 of the water flow guide, which is engaged with the water outlet at the bottom 40 of the dehydration tub 30 . Along the rear edge of each side wall 82 are a number of regular locking projections 84 .

Along the two perpendicular lines of the two lines of the locking projections 84 of the corresponding water flow directors 80 , there are many regular locking grooves 52 on the side wall of the tub body 50 . The locking protrusion 84 of the water flow guider 80 may be inserted into the locking groove 52 of the tub body 50 .

As shown in Figure 7b, when the locking protrusion 84 of the water flow guide 80 is inserted into the locking groove 52 of the barrel body 50, the rear end of the protrusion 84 bends outside the barrel part 50 and is placed on the barrel part 50. on the outside. The water flow guide 80 is installed on the staving 50 so that the rear edge of the two side walls 82 of the guide 80 is in close contact with the inner surface of the staving 50 without any gap between the side walls 82 of the guide 80 and the staving 50 form.

In addition, the bottom of the water flow guide 80 and the bottom of the dehydration bucket 30 are tightly installed together by the hook 83 around the water outlet 47, so that the bottom 40 of the water flow guide 80 and the bucket 30 has a smooth surface without The undesired annular rim of a conventional washing machine as shown in FIG. 3 . The mounting structure of the hook 83 of the water flow guide 80 and the bottom 40 of the dehydration tub 30 will be described below with reference to FIG. 8 .

Since the water flow guide of the present invention is tightly installed on the dehydration bucket 30, no gap is formed between the guide 80 and the bucket 30, so the water flow directed to the guide 80 is smoothly guided to the top of the guide 80, No leakage occurs at the junction between the side wall of the guide 80 and the barrel 50 .

Fig. 8 is a partial sectional view of the dehydration bucket of the present invention, showing the ascending water flow guide and the installation structure installed at the bottom of the dehydration bucket.

As shown, the hook member of the water flow director 80 includes a horizontal portion 83a and a vertical portion 83b. The horizontal portion 83a protrudes horizontally rearward from the lower portion of the guide 80, and the vertical portion 83b protrudes downward from the rear end of the horizontal portion 83a. Projecting downward along the inner edge of the spout 47, an engaging projection 47a is formed to engage with the vertical portion 83b of the hook member 83. As shown in FIG.

Therefore, when the hook 83 of the water flow guide 80 contacts the engaging protrusion 47a of the water outlet 47 at its horizontal portion 83a and vertical portion, the lower end of the vertical portion 83b is bent to cover the lower end of the protrusion 47a. A hook 83 is fitted to the bottom 40 of the dehydration tub 30 around the water outlet.

As mentioned above, the water flow guide 80 is in contact with the body 50 of the dehydration tub 30 at its side walls 82 and is in contact with the bottom 40 of the tub 30 around the water outlet 47 at its lower end. There is no gap at the seam between the guide 80 and the dehydration bucket 30, so the water flow directed to the guide 80 can be smoothly guided to the upper end of the guide 80, not from the joint of the barrel body 50 and the guide 80. leaked everywhere. In addition, laundry or debris will not be blocked or deposited at the seam of the tub body 50 and the guide 80 .

The water flow guide 80 and the dehydration bucket 30 are preferably made of the same material, such as stainless steel. Thus the water flow guide 80 has the same coefficient of thermal expansion as the tub 30, so even when hot wash water is contained in the wash tub 2, the guide 80 is not thermally deformed (see FIG. 1).

The curved cover 70 covers the water inlet 46 and the water outlet 47 at the bottom outer side of the dehydration tub 30 so that washable water is guided from the water inlet 46 to the water outlet 47 to guide the water to the water flow guide 80 .

The lower part of the cover 70 is provided with an engaging edge 71 which engages with the inner edge of the water inlet 46, while the upper part of the cover 70 has a plurality of screw holes 72 which receive fixing screws 73. In order to install the lid 70 on the bottom 50 of the dehydration bucket 30, the engaging edge 71 of the lid 70 is assembled with the inner edge of the water inlet 46, and then the upper end of the lid 70 is assembled on the top of the bottom 40, and screwed with many set screws. A screw hole 72 passes through the upper end of the bottom 40 . The cover 70 thus guides the wash water from the water inlet 46 to the water outlet 47 , thereby directing the water to the water flow guide 80 .

The operation effect of the vertical axis washing machine with the dehydration tub 30 and the ascending water flow guide 80 of the present invention will be described below.

After the laundry is put into the dehydration bucket 30, when the washing machine is turned on, a predetermined amount of water is put into the laundry bucket 2. Next, the reversible drive motor 5 is turned to generate a rotational force, which is transmitted to the agitator 4 through the energy transfer unit 6, thus rotating the agitator 4 in the opposite direction. Thus the agitator 4 generates a washing water flow, and when the water flow and other clothes rub against the inner surface of the dehydration tub 30, the clothes are forced to move along the water flow, thus washing the clothes.

In such a case, part of the water flow generated by the agitator 4, through the water inlet 46 and the water outlet 47 (formed on the bottom 40 of the bucket 30), can be directed to the water flow guide 80 and rise through the guide 80 to reach The top of the guide 80. After passing the burlap bag 11 at the top of the guide 80 , the rising water in the guide 80 is discharged from the guide 80 onto the clothes contained in the tub 30 . The discharged water hits the laundry, so the washing effect of the washing machine is improved. In addition, in the laundry mode, impurities such as lint can be effectively removed from the wash water.

The water flow guide 80 is tightly installed on the dehydration bucket 30, and no gap is formed at the seam of the guide 80 and the bucket 30, so that the water flow guided to the guide 80 is smoothly guided to the top of the guide 80, and Do not leak from the joint of the guide 80 and the bucket 30. In addition, laundry or debris will not clog and deposit at the seam of the guide 80 and tub 30 .

When the washing mode is completed after a predetermined time from the start of washing, washing water is drained from the washing tub 2 through the drain hole 8 before the washing operation mode in which detergent is removed from the laundry. After the cleaning operation is completed, the dehydration bucket 30 is rotated at a high speed on the dehydration shaft 6a, so that the water in the clothing can be spun off, and the laundry process is completed.

As described above, the present invention provides a vertical axis type washing machine having a small size and simple structure rotary dehydration shaft support which can be easily installed on the dehydration tub without fixing screws. on the bottom. In this way, during the production process of the washing machine, the cost and maintenance time of this type of washing machine can be reduced.

In the washing machine, although the washing machine is repeatedly used for a long time, the dehydration shaft support is firmly fixed on the bottom of the dehydration tub, thereby prolonging the service life of the washing machine.

In addition, the small-sized dehydration shaft support and the dehydration tub are made of the same material, which prevents corrosion due to a voltage difference between the shaft support and the dehydration tub, and also prevents corrosion caused by erosion of the shaft support. dirty laundry.

The repeated depression and protrusion of the bottom of the dehydration bucket can form reinforcements that increase the structural strength of the bottom, thus making it possible to increase the durability of the dehydration bucket.

In the washing machine, the ascending water flow guide is installed on the dehydration tub without forming a gap at the seam of the tub and the guide so that a sufficient amount of wash water is drained from the top of the guide to the clothes. Therefore, it is possible to improve the washing effect of the washing machine, and effectively remove impurities from the washing water.

Since the water flow guide and the dehydration bucket are installed together, there is no gap formed at the seam of the bucket and the guide, and the clothing and miscellaneous materials will not be blocked and deposited at the joint of the guide and the bucket. This makes it possible to prevent damage to the laundry and soiling of the laundry due to the sedimentation of the impurities.

In the washing machine, the water flow guide and the spin tub are made of the same material so that heat deformation can be prevented when hot water is used in the washing process. This makes it possible to prevent damage and soiling of the laundry and furthermore prolongs the service life of the water flow guide.

Although the preferred embodiment of the present invention has been schematically described, those skilled in the art will understand that various changes such as additions and reductions can be made to the present invention without departing from the spirit and scope disclosed in the claims of the present invention .
