Description

The present invention relates to a drum-type washing machine in which a rotatable washing drum having a rotation axis centered horizontally is supported in an anti-vibration manner in an outer frame casing.

  The drum type washing machine of the present invention also includes a drum type washing machine having a drying operation function.

A drum type washing machine is described in Japanese Patent Application Laid-Open No. 2003-79995 (Patent Document 1). This drum-type washing machine has a configuration in which the rotation axis of the washing drum tub is obliquely installed so that the charging port is obliquely upward, and the outer tub in which the washing drum tub is placed is supported by the suspension in a vibration-proof manner.

JP 2003-79995 A

The drum type washing machine makes it easy to put the laundry in and out of the laundry drum by inclining the rotation axis of the laundry drum tub so that the laundry inlet is directed upward.

However, while increasing the inclination angle of the inclination, it becomes easier to put in and out the laundry,
Detergency of laundry is reduced.

Further, if L is larger than d in comparison with the radius d and the depth L of the washing drum, the mechanical force due to tapping is reduced, and the cleaning power is reduced. At the same time, the depth dimension of the outer frame casing of the drum type washing machine increases, and the thickness cannot be reduced.

On the other hand, when d is larger than L, the mechanical force by tapping is increased and the damage of the laundry is increased. At the same time, the width and height of the outer frame casing increase, and the size reduction cannot be achieved. In addition, vibration and noise increase due to an increase in centrifugal force during dehydration.

Further, when the thickness is reduced, the frontage width of the drum type washing machine is increased. Since the waterproof pan on which the drum-type washing machine is placed becomes large, a large space is required.

Moreover, the drainage hose provided on the side surface of the drum type washing machine protrudes from the lower base portion and extends outward. When you don't wash, drain the hose on the side of the drum-type washing machine.

Since the drainage hose protrudes from the base part and is curved to a large extent and makes a business trip from the side of the drum-type washing machine, it is necessary to provide a place with a wide opening that allows for a protruding margin.

  An object of the present invention is to provide a drum-type washing machine that is thin, easy to put in and out laundry, and has good cleaning power.

  The present invention relates to a drum washing machine comprising a rotatable washing drum, an outer tub in which the washing drum is placed and storing washing water, and an outer frame housing in which the outer tub is placed. Liters to 104 liters, the depth L of the washing drum is 280 mm to 310 mm, and the relationship between the radius d of the washing drum and the depth L of the washing drum is d / L = 0.9 to 1.1 Features.

  According to the present invention, it is possible to provide a drum-type washing machine that is thin, easy to put in and out laundry, and has good cleaning power.

As shown in FIGS. 1 and 5 to 9, the drum-type washing machine includes an outer frame casing 1, an outer tub 2 placed in the outer frame casing 1, and a laundry that is rotatably provided in the outer tub 2. It has a drum 3. The outer tub 2 is supported in a vibration-proof manner by a vibration-proof support means.

The outer frame housing 1 has a housing body 4 and a base 5 on which the housing body 4 is placed. The base portion 5 is made of a synthetic resin and has a number of lattice-like reinforcing structure portions 6 as shown in FIG.
Support legs 7 are provided at four corners of the bottom surface of the base portion 5.

The opening width and depth width of the base portion 5 are made smaller than the opening width and depth width of the outer frame housing 1.

That is, the outer frame casing 1 has a wide frontage width due to a relationship in which the diameter is increased by the amount by which the length (depth) of the washing drum 3 in the front-rear direction is reduced. Since the outer size of the outer frame housing 1 is thin, there is an advantage that the protruding of the placed drum type washing machine is reduced. Further, since the depth of the washing drum 3 is shallow, it is easy to put in and out the laundry.

However, since the opening width of the drum-type washing machine is increased, the waterproof pan 11 (FIGS. 3 and 4) is required to be slightly larger. If the large waterproof pan 11 is used, the merit of making the outer frame casing 1 thinner and thinner is lost. Therefore, the frontage width and the depth width of the base portion 5 are determined by the outer frame housing 1.
By making it smaller than the frontage width and the depth width, it is possible to cope with the small waterproof pan 11, so the merit of thinning can be used effectively. There is a good point that does not take up a large place to install the drum type washing machine.

  The waterproof pan is a plastic dish-shaped water tray.

As shown in FIGS. 1 and 3, the drain hose 8 protrudes from the right side surface of the base portion 5 and extends outward. When washing is not performed, as shown in FIG. 3, the drainage hose 8 is placed against the side surface of the housing body 4.

A hook (not shown) is provided on the distal end side of the drain hose 8. By hooking the hook into the hook hooking hole 9 (FIG. 1) provided on the side surface of the housing body 4, the drainage ho

The support 8 is leaned so as to be along the side surface of the housing body 4.

As shown in FIGS. 5 to 11, the housing body 4 includes left and right side plates 20 formed of steel plates (plate thickness 0.7 mm), and steel plates ( Plate thickness 1.6mm
) And the steel plate (plate thickness 1.
6 mm) the rear lower reinforcing plate 22, the rear upper reinforcing plate 23 of the steel plate (plate thickness 1.6 mm) connected to the rear upper portion of the both side surface portions 20, and the upper side of the both side surface portions 20. And a ceiling reinforcing plate 24 made of steel plates (plate thickness 1.6 mm).

The front reinforcing plate 21, the rear lower reinforcing plate 22, the rear upper reinforcing plate 23, and the ceiling reinforcing plate 24 are fastened to the both side plates 20 with screws. Since both side plates 20 have a resin coating on the surface, screw fastening is employed without welding.

The housing body 4 is strong because it is configured by combining the both side plates 20 of the steel plate, the front reinforcing plate 21, the rear lower reinforcing plate 22, the rear upper reinforcing plate 23, and the ceiling reinforcing plate 24. The housing body 4 sufficiently withstands large load vibration caused by unbalance of the washing drum 3 during the dehydrating operation.

As shown in FIG. 1, the rear cover 25 is a lid that closes the rear opening of the housing body 4 that opens between the rear lower reinforcing plate 22 and the rear upper reinforcing plate 23, and is a steel plate (plate thickness: 0.3 mm). It is made with. Since the rear cover 25 is not subjected to large load vibration due to unbalance, the weight is reduced by making it thinner than the side plates 20.

Further, as shown in FIGS. 1, 2, 5, and 9, the housing body 4 covers the front cover 26 made of synthetic resin so as to cover the front reinforcing plate 21 and the ceiling reinforcing plate 24. A top cover 27 made of a synthetic resin to be covered, a corner cover 29 made of a synthetic resin to cover the front corner portions of the side surface portions 20, a lower side of the front corner portion, and a lower portion of the casing body portion 4. It has a lower cover 40 made of synthetic resin that covers the side.

The casing main body 4 has an appearance excluding the rear side in the double-sided face plate 20, the front cover 26, the top cover 27,
The corner cover 29 and the lower cover 40 are formed. Since the appearance is formed of synthetic resin parts except for both side plates 20, various shapes and colors can be freely selected.

As shown in FIGS. 1, 2, 7, and 9, the laundry outer lid 41 opens and closes the laundry entrance / exit 42 of the front cover 26. As shown in FIG. 7, the hinge 43 of the washing outer lid 41 is supported by the front reinforcing plate 21.

The push button 44 is provided on the upper right side of the front cover 26 as shown in FIGS. 1, 2, 5, and 9. When the push button 44 is pressed, the outer lid 41 for washing is unlocked and the outer lid 41 for washing is opened. The laundry is taken in and out.

The front cover 26, the upper cover 27, the corner cover 29, and the lower cover 40 are separately formed of synthetic resin. Since it is formed of synthetic resin, various shapes and color schemes including curved surfaces can be arbitrarily selected.

The upper surface cover 27 has an upper surface portion 27a and a corner portion 27b. The upper surface portion 27a and the corner portion 27b are separately molded and assembled into a single body using a coupling means such as a locking claw. Upper surface part 2
The reason why the 7a and the corner portion 27b are separately formed is to make them different in color.

The upper surface portion 27a has a flat portion 27c that is somewhat depressed in the center. The flat portion 27c is made of detergent or

It can be used as a temporary table to place a funner temporarily.

The upper surface portion 27a is provided with a detergent charging container 45 on the left end front side and a finishing agent charging container 46 on the right end front side in a detachable manner.

The lower cover 40 has a front surface portion 40a and a corner portion 40b. The front surface portion 40a and the corner portion 40b are separately molded and assembled into a single body using a coupling means such as a locking claw. Front part 4
The reason for separately forming 0a and the corner portion 40b is to make the colors different.

A lint outer lid 47 is detachably provided on the front surface portion 40a. The lint outer lid 47 is removed, and the lint pocket 48 placed inside is removed.

The corner cover 29, the corner portion 27b, and the corner portion 40b have curved surfaces. Because of the corner cover 29, the corner portion 27b, and the corner portion 40b, the periphery of the front corner on the lower side of the outer frame housing 1 has a curved shape in the vertical direction, so there is no cornering and the contact is soft. Convenience is good.

Since the corners at both the left and right corners of the corner portion 40b are formed in a substantially spherical surface, the hitting is alleviated and the usability is improved.

As shown in FIGS. 1 to 4 and FIGS. 15 to 19, the side plates 20 have curved portions 20 a, 20 b, 20 c, and 20 d that are curved on the upper and lower sides and the front and rear sides, and a flat central flat plate provided at the center. Part 2
0e. The curved portions 20a, 20b, 20c, and 20d are curved so as to protrude toward the surface side on which the resin coating is applied.

Both side plates 20 are 0.6 mm steel plates, but curved portions 20a around the central flat portion 20e.
, 20b, 20c, and 20d are provided to increase the rigidity in the vertical and horizontal directions. Thereby, the housing body 4 sufficiently withstands large load vibration due to the unbalance of the washing drum 3.

The center flat part 20e has two lower transport handles 60 and 61 provided in the front and rear side, a transport upper handle 62 provided on the upper side, and a hook hole 9. Lower handle 60 for transportation,
61, The upper handle 62 for conveyance provided in the upper side, and the hook hooking hole 9 are formed by punching the steel plate of the side plate 20 by press working.

Since the flat central flat portion 20e is punched out by pressing, it is easy to punch.

The lower handling handles 60, 61 and the upper handling handle 62 provided on the upper side are formed by fitting a synthetic resin handle or bar into the punched hole.

The hole punched out by the handle or bar is covered, so it is easy to put it on and safe. Moreover, the hook hooking hole 9 is bent inward to eliminate sharp corners.

As shown in FIGS. 8, 10, and 11, two upper rear handles 63 and 64 for transportation are provided side by side.

Since the lower transport handles 60 and 61 are provided side by side, the drum type washing machine can be carried so that two transporters hold the front and rear. Even a heavy drum type washing machine of about 80 kg can be easily transported by two transporters.

The transport upper handle 62 and the transport upper rear handles 63 and 64 are used when changing the installation direction of the drum type washing machine or placing the drum type washing machine on the waterproof pan 11. In this case, four handles were provided so that two people could work.

In addition, a handle is provided in the outer frame casing of the present embodiment. When carrying the body manually, the weight of the body is heavy, so it is often lifted by two people from both sides. In that case, it becomes easier to pass through the narrower passage when the frontage width is smaller than the depth dimension. In addition, since the rotation axis of the washing drum is arranged in a state inclined from the horizontal, the depth tends to increase particularly.

  Therefore, such a configuration is preferable.

As shown in FIGS. 15, 16, and 18, the side plates 20 are curved in the vertical direction on the lower side. In this curved shape, the lower curvature R1 is made smaller than the upper curvature R2. Both side plates 20 have a lower connection flange 65 at the lower end.

As shown in FIG. 15, the both side plates 20 come into contact with the lower connection flange 65 so as to be placed on the base portion 5, and by tightening screws 66 inserted from below the base portion 5 to the lower connection flange 65, To be concluded.

As described above, the opening width of the base portion 5 is made smaller than the opening width of the housing main body portion 4. As shown in FIGS. 1 and 3, the drainage hose 8 protrudes from the side surface of the base portion 5 having a small opening width and extends outward.

The drainage hose 8 is accommodated so as to lean against the side plates 20. For this storage,
The drain hose 8 is curved. However, since the opening width of the base portion 5 is smaller than the opening width of the housing main body portion 4 and the lower side of the side plates 20 has a curved shape in the vertical direction, It does not occur that the drainage hose 8 partially bulges to the side and makes a business trip.

Thus, since the business trip due to the partial swelling of the drainage hose 8 does not occur, it is possible to provide a drum type washing machine that does not take up a large place.

Further, the curved shape of the side plates 20 is such that the upper curvature R2 is made larger than the lower curvature R1, so that the durability life against bending of the drainage hose 8 can be extended.

That is, when the drainage hose 8 is stored, the drainage hose 8 bends as the drainage hose 8 is raised and lowered. Since the upper curvature R2 is larger than the lower curvature R1, the bending radius of the drainage hose 8 is larger, bending fatigue is reduced, and the durability life is longer than that of the one made with a small curvature. Become.

Furthermore, since the lower curvature R1 is small and the upper curvature R2 is large, it is possible to reduce the gap interval (a) with the waterproof pan as compared with the one made with one large curvature. For this reason, the drainage hose 8 can be easily inserted even with a small waterproof pan. If the width is the same, the height (b) of the waterproof pan can be increased.

As shown in FIGS. 5, 6, and 10 to 12, the vertical reinforcing member 67 is a reinforcement of the lower part on the front side of the side plates 20. The longitudinal reinforcing member 67 is formed of a steel plate (plate thickness 1.6 mm).

As shown in FIG. 16, the side plates 20 include a front connection flange 80 and a rear connection flange 81.
And an upper connecting flange 82. As shown in FIGS. 10 to 13, the vertical reinforcing member 67

Fastened with screws to the lower side of the part connection flange 80.

The longitudinal reinforcing member 67 has a leg portion 83. The both side plates 20 are coupled to the base portion 5 by placing the leg portions 83 on the support bosses 84 of the base portion 5 and fastening them with screws. Vertical reinforcement member 67
The reinforcement of the diaphragm rib is formed.

Since the front side of both side plates 20 is firmly coupled to the base portion 5 using the vertical reinforcing member 67, it can withstand a large load vibration due to the unbalance of the washing drum 3.

As shown in FIGS. 10 and 11, the ceiling reinforcing plate 24 is formed by connecting the upper connecting flanges 8 of the side plates 20.
2 is fastened with screws. The rear lower reinforcing plate 22 and the rear upper reinforcing plate 23 are shown in FIGS.
As shown in FIG. 1, it is fastened to the rear connection flange 81 of the side plates 20 with screws.

As shown in FIGS. 6 and 9, the front reinforcing plate 21 is fastened to the front connection flange 80 of the side plates 20 with screws.

Since both side plates 20 have a strong structure in which the front side, the rear side, the upper side, and the lower side of the front side are assembled with reinforcing plates or reinforcing members, they can withstand large load vibration due to unbalance of the washing drum 3.

Further, the outer frame casing 1 has a front cover 26 whose outer appearance is made of synthetic resin, excluding the side plates 20.
Since the upper cover 27, the corner cover 29, and the lower cover 40 are formed, a drum-type washing machine having a good appearance can be provided.

The corner cover 29 and the lower cover 40 are attached to the front side of the side plates 20 as shown in FIGS. 1, 2, 9, and 10. The front side of the both side plates 20 has a cover support step 85 that is narrowed inward.

Since the surfaces of the corner cover 29 and the lower cover 40 attached so as to fall into the cover support step 85 are flush with the surfaces of the side plates 20, the appearance is good.

As shown in FIGS. 9 and 13, the cover support step 85 has a locking hole 86. By locking the locking claw 87 provided in the corner cover 29 or the lower cover 40 in the locking hole 86,
The corner cover 29 and the lower cover 40 are fixed to the side plates 20.

As shown in FIGS. 7 and 8, the outer tub 2 has a large number of reinforcing ribs that run in a lattice pattern on the outer surface. By reinforcing the outer tub 2 made of a synthetic resin with these many reinforcing ribs, the outer tub 2 can withstand a large load vibration due to unbalance of the washing drum 3.

The electric motor 88 is fixedly supported at the rear rear center of the outer tub 2. The washing drum 3 is fixed to the rotating shaft of the electric motor 88 and is driven to rotate by the electric motor. 40 to 50r for washing and drying
The motor rotates at a low speed of pm.

In the dehydration operation, the washing drum is rotated at a high speed by an electric motor to perform centrifugal dehydration. A large load vibration due to unbalance of the washing drum 3 occurs during centrifugal dehydration. The drum type washing machine has a structure that can withstand this large load vibration.

  Next, another embodiment will be described with reference to FIGS.

This embodiment is a drum type with a thin outer frame housing that allows easy loading and unloading of laundry and good cleaning power.

It relates to a washing machine. In this embodiment, the configuration in which the width of the base and the depth of the base portion described in the previous embodiment are smaller than the width of the front and the width of the outer casing.

As shown in FIG. 20, the outer dimensions of the outer casing 1 are 1100 mm in height H, 650 mm in width W on the front side, and 610 mm in depth D.

This external dimension is a case where the washing capacity is 8 to 10 kg and the dry capacity is 6 to 8 kg. When the washing capacity and the drying capacity change, the size of the washing drum also changes, so that the outer dimensions change.

The outer frame housing 1 can be made thinner by increasing the diameter of the washing drum 3 and reducing the depth, thereby reducing the depth of the outer tub 2.

Moreover, since the depth of the washing drum 3 becomes shallow by making it thin, it becomes easy to put in and take out the laundry. If the laundry drum 3 is tilted so that the laundry outlet / outlet is directed upward, the laundry can be easily taken in / out, but it goes against thinning, and the tapping (detergency) of the drum type washing machine decreases.

Therefore, the inclination θ of the washing drum 3 was set to about 10 ° to 20 °, and the relationship between the diameter and the depth of the washing drum 3 was examined.

  This will be described with reference to FIGS.

As the washing drum 3 rotates, the laundry 90 is lifted up by the lifter 91 and naturally falls and washed.

When the rated capacity of the laundry 90 is 8 kg and the specific volume is 9 to 13 (L / kg), the internal volume V liter of the washing drum tub is about 72 liters to 104 liters.

  When it is within this range, the relationship between the diameter and depth of the washing drum 3 is as follows.

  When the diameter D1Φ is 540 mm, the depth L is 315 mm.

  When the diameter D1Φ is 660 mm, the depth L is 205 mm.

If the depth L is 315 mm, the outer casing 1 cannot be thinned. When the diameter D1Φ is 660 mm, the depth L is 205 mm and the thickness is reduced. However, the width (W) of the main body housing 1 increases as the diameter increases.
Will become bigger. For this reason, the installation property to a house worsens.

Therefore, in order to achieve an appropriate thinning in consideration of the ease of installation in a house, the specific volume is 9 to 13 (kg
), When the rated capacity is 8 kg, 80 to 88 (L) is desirable. From this result, it is desirable that the depth L is 280 to 310 mm and the diameter D1Φ is 600 mm.

Further, the detergency and damage will be described with reference to FIG. 23 based on the relationship of the diameter DΦ of the washing drum / the depth L of the washing drum.

In this figure, the left vertical axis represents the cleaning power index, the right vertical axis represents the MA value (scratch value), and the horizontal axis represents the ratio of the diameter DΦ of the washing drum 3 / the depth L of the washing drum 3. Solid line is detergency index, dotted line is MA
The value is shown.

This data is a measurement value when the inclination angle θ of the washing drum tub 11 is set to 10 ° to 20 °.

The MA (Machine Action) test method is a damage evaluation method for the laundry 90.

MA that evaluates the degree to which the laundry 90 is damaged by physical action.
In the (Action) test method, a 400 mm square plain woven cotton cloth obtained by punching five circles having a diameter of D35 mm is used. Inspect and evaluate the damage to the laundry due to the sum of the number of frays in the five circles using mechanical force such as washing and tapping at the time of rinsing.

The higher the MA value, the stronger the mechanical force received by the laundry and the better the cleaning power, but the laundry 90 becomes more severely damaged.

The MA value in a standard washing course is about 45 to 55. If it is less than that, the removal of dirt will worsen. If it is more than that, cloth damage will become intense and the function as a washing machine will be impaired.

If the washing time is lengthened, the total amount of mechanical force received by the laundry 90 is increased, and on the other hand, the cloth damage is also increased. Further, when the diameter of the washing drum 3 is increased, the effect of tapping and washing is improved and the dirt is better removed, but the fabric damage is increased.

Considering the advantages and disadvantages related to the washing performance, after various examinations and trials, the ratio (d / L) of the “radius dΦ / depth L of the washing drum 3” of the washing drum 3 is 0.9 to 1. It was determined that the range of 1 was appropriate. D is the radius of the washing drum 3.

In addition, by making the ratio (d / L) in the range of 0.9 to 1.1, the laundry 90 can be easily taken in and out, and the drum that has been appropriately thinned in consideration of the ease of installation in a house. Type laundry dryer can be provided.
