Abstract

PROBLEM TO BE SOLVED: To make a device small and light and to quickly execute an operation for putting-in the wash by permitting washing water to flow-in to a part where the pressure force of the wash is reduced and permitting a water liquid to flow-out from a part where pressure force is increased to the outside of the wash. SOLUTION: The washes 2a, 2b,... are alternately pressurized in a left half part and the right half one and it is repeated when pressing plates 9A and 9B are repeatedly inclinedly moved between a left inclination posture 9A and the right inclination posture 9B in a state where the washes 2a and 2b are held between the pressure plates 9A and 9B and base plates 16 and 16'. When a part of the washes 2a and 2b is locally observed, they are pressurized or released from pressure. The washes released from pressure absorb washing water inside while expanding by the elasticity of animal or plant source clothes themselves. When pressure force is added, absorbed washing water is pushed-out. Thus, washing water is permitted to flow into the inside of the washes 2a and 2b so that at effect on washing away stain or rinsing is improved.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for washing clothes and other textiles in general using an aqueous solution of a detergent, and to an apparatus therefor, and more particularly to a method for removing contaminants that could not be removed by dry cleaning using a solvent. It is suitable for removal.

[0002]

2. Description of the Related Art Natural fiber products such as wool, animal hair, silk, cotton, and hemp, and natural leathers such as fur and leather (for convenience of explanation,
(Whereafter referred to as animal and vegetable clothing) When washing with an aqueous solution of soap or a surfactant when washing with an aqueous solution of soap or detergent, the laundry is shrunk or hardened. To prevent such problems, dry using a non-aqueous solvent. Cleaning is being performed. However, non-aqueous solvents may cause environmental pollution and hygiene problems, have a risk of fire, and are relatively expensive. Water-drying washing techniques that do not shrink or harden animal and vegetable clothing are being developed. This water-dry type washing has come into practical use with a shrinkage-hardening inhibitor (for example, Japanese Patent No. 182516) for preventing deterioration of animal and vegetable clothes due to water. As for a method and an apparatus for water-dry washing using such agents in combination, for example, Japanese Patent Application Laid-Open No. 9-103594, “Washing Method and Washing Apparatus” is known.

FIG. 5 shows an example of a known water-drying type washing apparatus. FIG. 5 (A) is a schematic diagram showing a state in which a laundry object put in a basket is immersed in washing water in a washing tub and washed. Sectional drawing, (B) is a single-piece perspective view which extracted and drawn the spacer plate which is a component of the said water-drying type washing machine. Are placed in a basket 1, and a spacer plate 3 having a specific gravity as large as possible is sandwiched between the laundry. And washing water 4
The basket 1 is suspended in the washing tub 5 filled with water, and the basket 1 is reciprocated up and down as shown by the reciprocating arrows ab, and the washing water is sprayed from the side as shown by the arrow c. Can be FIG. 5A is a schematic diagram.
Although the injection of the wash water is indicated by an arrow c, as a specific structure, a nozzle for injecting the wash water and a pump for pumping the wash water are provided. .. Are swung up and down by the vertical movement of the basket 1. At this time, the inertia force of the spacer plate 3 acts to repeatedly apply a pressing force to the laundry. When the dirt on the laundry is removed by repeatedly receiving the pressing force and receiving the injection of the washing water (arrow c), the laundry is similarly rinsed in water, and then a diaphragm plate (not shown) is placed above the laundry. From the horizontal position, and presses the laundry with an air cylinder (not shown) to squeeze out moisture.

[0004]

According to the known water-drying washing technique described above, the water-based washing liquid can be made to flow into the laundry by using an inexpensive and harmless water-based washing liquid. However, (a) a nozzle or a pump for spraying the washing liquid must be provided in order to make the washing liquid flow into the laundry, so that the apparatus is complicated, large and heavy, and the manufacturing cost is high. Yes, (b) the basket must be placed in the washing tub and the nozzle must be installed facing the basket, so that there is less laundry to be stored than the inner volume of the washing tub, and (c) ) Since the spacer plate must be interposed between the laundry objects, it takes time to put the laundry object into the washing tub in preparation for washing, and also takes time to remove the laundry object from the washing tub. There is also the complexity of storing the spacer plate,
(D) Not only the laundry but also the basket in which the laundry is placed must be moved up and down in water, so that the required power is large. (E) The washing is performed to squeeze the washed and rinsed laundry. Since a squeezing member is required in addition to the rinsing member, the structure becomes complicated, the apparatus becomes large and heavy, and the manufacturing cost further increases. There is a problem.

The present invention has been made in view of the above circumstances, and has been known in the art. It is known that an inexpensive and harmless water-based washing liquid can be used to flow the water-based washing liquid into a laundry. FIG. 5) Without impairing the advantages, (a) the washing liquid can be flowed to the inside of the laundry without providing a nozzle or a dedicated pump, and (b) a large member separate from the washing tub. It is not necessary to provide a basket, and a large amount of laundry can be stored and washed and rinsed in comparison with the inner volume of the washing tub. (C) A rigid member having a large specific gravity between the laundry There is no need to sandwich the spacer plate,
(D) using components directly necessary for washing and rinsing,
An object of the present invention is to provide a simple, compact, lightweight, and water-drying type washing technique which requires less power and can squeeze out washing water from a washed article.

[0006]

The basic principle of the present invention created to achieve the above object will be briefly described with reference to FIG. 1 corresponding to one embodiment of the present invention.
Are directly stored without being put in a basket, and a push plate (for example, 9A) is placed thereon.
Position. This push plate has a plurality of rods (10
a, 10a ', etc.) and is supported by a push plate drive mechanism 12, which is lifted and lowered by a lift cylinder 14. The above-described push plate driving mechanism 12 includes, for example, a crank mechanism 12.
The rods are moved up and down in coordination with each other by means of a and 12b.
It is repeatedly tilted back and forth between the posture and the 9B posture, or vertically moved in the horizontal posture. In this operation,
Washing is performed by placing an aqueous detergent solution in the washing tub, and rinsing is performed by adding water. After rinsing, drainage is performed, and the push plate driving mechanism 12 is
Is lowered, the push plate pushes down the laundry to perform a squeezing action. In the present invention, the water refers to substantially pure water, and may contain impurities such as industrial water. The term "detergent" is a generic term for chemicals added to water for washing, and is a generic term for soaps, surfactants, enzyme agents, anti-shrinkage agents, and the like. Washing water is a general term for water and an aqueous detergent solution used for washing and / or used for washing, and may include washed foreign substances.

The method according to the first aspect of the present invention is based on the principle described above. A laundry object is placed in a washing tub, immersed in washing water, and a push plate is positioned on the laundry object. The above-mentioned push plate is alternately tilted in the opposite direction from a substantially horizontal neutral posture, or in a form in which the inclination direction relative to the horizontal plane is continuously rotated 360 degrees all around.
By repeatedly swinging, the distribution of the pressing force received by the laundry is periodically changed, and the washing water is caused to flow into the portion where the pressing force of the laundry is reduced,
The washing liquid is caused to flow out of the laundry from the portion where the pressing force is increased, and this operation is repeated. According to the method of the first aspect described above, the distribution of the pressing force changes periodically while the laundry is pressed by the pressing plate in the washing liquid. For this reason, when an arbitrary part of the laundry is considered locally, the pressing force received from the pressing plate periodically changes. As a result, when the pressing force decreases, the washing liquid permeates and flows into the object to be washed, and when the pressing force increases, the soaked washing liquid flows out of the object to be washed. The washing function is performed, and contaminants adhering to the laundry are dissolved in the washing liquid and removed. Since the above operation is performed by placing the laundry in the washing tub without placing it in the basket, it is possible to put a large amount of laundry in the relatively small laundry tub and perform water-dry washing. Also, there is no need to swing the basket up and down, so less power is required. In addition, since there is no need to insert a spacer plate between the laundry items, the operation of loading the laundry item into the washing tub can be performed quickly and easily, and the washed laundry item is carried out of the washing tub. Can be performed quickly and easily.

According to a second aspect of the present invention, the object to be washed is placed in a washing tub, immersed in washing water, and a push plate is positioned on the object to be washed. By repeatedly moving up and down in a horizontal position, the pressing force received by the laundry is changed periodically, and when the pressing force of the laundry decreases, the washing water flows into the laundry, and When the pressing force is increased, the washing liquid is caused to flow out of the laundry, and this operation is repeated.
According to the above-described method of the second aspect of the present invention, the magnitude of the pressing force periodically changes while the laundry is pressed by the push plate in the washing liquid. For this reason, when an arbitrary portion of the laundry is considered over time, the pressing force received from the pressing plate periodically changes. Thereby, when the pressing force decreases, the washing liquid infiltrates into and flows into the laundry,
When the pressing force increases, the infiltrated washing liquid flows out of the laundry, and this operation is repeatedly performed to perform a push-washing action, and contaminants adhering to the laundry are dissolved into the washing liquid. Removed. Since the above operation is performed in the washing tub without putting the laundry in the basket,
A large number of items to be washed can be put into a relatively small washing tub and subjected to water-dry washing. Also, there is no need to swing the basket up and down, so less power is required.

According to a third aspect of the present invention, in addition to the constituent features of the first or second aspect of the present invention, an object to be washed put in a washing tub is placed on a floor surface in the washing tub. And the amount of bending of the elastic member is changed with a change in the pressing force applied to the laundry by the movement of the push plate, and the washing water is relatively distributed around the laundry. It is characterized by violently flowing. According to the above-described method of the third aspect of the present invention, when the push plate is driven to repeatedly tilt or move up and down repeatedly, the object to be washed repeatedly bends by bending the elastic member, or moves repeatedly up and down. In this way, the washing water is repeatedly tilted or moved up and down in the washing water, whereby the washing water is agitated by the washing object, and as a result, the flow of the washing water violently collides with the washing object. , The washing effect is further enhanced.

According to a fourth aspect of the present invention, in addition to the constituent elements of the first to third aspects of the present invention, a plurality of articles to be washed are stacked in the washing tub,
A water-impermeable sheet-like member is sandwiched between vertically adjacent laundry objects to simultaneously wash the plurality of laundry items and to prevent color transfer between the plurality of laundry items. And According to the above-described method of the fourth aspect of the present invention, even if a plurality of types of laundry are put in a water-based washing liquid and simultaneously water-washed, color transfer may occur between different types of laundry. There is not. As described above, when a plurality of objects to be washed with each other that may be mutually color-transferred can be simultaneously water-dry-washed, the work efficiency can be directly improved. In this method, a means for selecting the garment according to the kind of the animal or plant garment is omitted, and the danger of causing color transfer due to erroneous selection is eliminated. Under the current situation where the types of dyes and mordants are increasing due to the recent development of dyeing technology for clothing and new dyeing methods are being developed one after another, sorting work in preparation for water-dry washing is highly knowledgeable and skilled, and Since a great deal of time and labor is required, the economical effect of omitting this operation is great, and the practical value of eliminating the possibility of human error (misselection) is great.

According to a fifth aspect of the present invention, in addition to the constituent features of the first to fourth aspects of the present invention, the washing water is discharged from the washing tub after the push plate is moved and washed. The laundry is pressed by the push plate to squeeze out the washing water contained in the laundry. According to the method of the fifth aspect described above, in the squeezing step after washing, a large-sized component dedicated to squeezing work is not required, and the equipment for performing the washing step (push plate and its driving means) , The washing water contained in the laundry can be squeezed out.

A structure in which the push plate is alternately swung between a state in which the push plate is inclined relative to the horizontal posture and a state in which the push plate is inclined in a direction opposite to the above-described inclination, or the push plate has an inclination direction of the push plate Swings around 360 degrees around Characterized in that it is a caulking structure. According to the apparatus of the sixth aspect described above, each of the plurality of rods is moved up and down by the operation of the push plate driving mechanism, and the push plate connected to the lower ends of the plurality of rods is covered. Since the laundry is repeatedly tilted back and forth in contact with the upper surface of the laundry, the laundry is pushed and washed in the washing water filled in the washing tub, and the laundry can be washed without providing the washing liquid jetting means. The washing liquid flows into the inside of the washing machine, and contaminants dissolve in the washing liquid and are removed. The configuration of the device according to the present invention does not include a basket that stores laundry and swings up and down in the washing tub, and is directly inserted into the washing tub. Therefore, the washing tub can be made smaller and lighter than the amount of laundry to be washed in one operation. In addition, since a nozzle for injecting the washing liquid is not provided in the washing tub, the washing tub can be smaller and lighter. Further, since a pump for injecting the washing liquid and a driving mechanism thereof are not required, the entire apparatus is small, light and inexpensive. In addition, since a spacer plate, which is a large member having rigidity, is not required, handling is easy, and there is no dead space occupied by the spacer plate. You can put it inside and wash it with water.

According to a seventh aspect of the present invention, there is provided a washing tub having a water supply means for feeding water, an injection means for injecting a detergent, and a drainage means for discharging water or an aqueous solution. A push plate positioned on the object to be washed placed in the tub, a plurality of substantially vertical rods connected to the push plate and positioned above the push plate, and the plurality of rods A push plate drive mechanism connected to the upper end of the rod, wherein the push plate drive mechanism is connected to the plurality of rods by reciprocatingly driving each of the rods up and down. The push plate is reciprocated up and down repeatedly while maintaining a substantially horizontal posture. According to the apparatus of the seventh aspect described above, each of the plurality of rods is moved up and down by the operation of the push plate driving mechanism, and the push plate connected to the lower ends of the plurality of rods is covered. Since the laundry is repeatedly moved up and down while being in contact with the upper surface of the laundry, the laundry is pushed and washed in the washing water filled in the washing tub, and the laundry can be washed without providing the washing liquid jetting means. The washing liquid flows into the inside of the washing machine, and contaminants dissolve in the washing liquid and are removed. The configuration of the device according to the present invention does not include a basket that stores laundry and swings up and down in the washing tub, and is directly inserted into the washing tub. Therefore, the washing tub can be made smaller and lighter than the amount of laundry to be washed in one operation. Moreover,
Since the nozzle for injecting the washing liquid is not provided in the washing tub, the washing tub is smaller and lighter. Further, since a pump for injecting the washing liquid and a driving mechanism thereof are not required, the entire apparatus is small, light and inexpensive.
In addition, since a spacer plate, which is a large member having rigidity, is not required, handling is easy, and there is no dead space occupied by the spacer plate. You can put it inside and wash it with water.

According to an eighth aspect of the present invention, in addition to the constituent features of the sixth or seventh aspect of the present invention, the push plate driving mechanism can be moved vertically above the washing tub. And a lifting cylinder means for reciprocating the push plate driving mechanism in a vertical direction, and the lifting cylinder means can adjust the magnitude of its output in at least two stages. It is characterized by the following. According to the apparatus of the eighth aspect described above, the push plate driving mechanism for supporting the push plate in a suspended manner is guided above the washing tub so as to be able to move up and down, and the up and down movement is driven by the cylinder means. Thus, when the push plate driving mechanism is raised, the push plate is pulled up, and the operation of putting the article to be washed in and out of the washing tub becomes free. Further, when the push plate driving mechanism is lowered, the push plate is lowered and comes into contact with the laundry to be able to perform the push washing action.
Further, when the push plate driving mechanism is lowered with a strong force in a state where the washing water in the washing tub is drained and the inside of the tub is emptied, the push plate strongly presses down the laundry to perform the squeezing operation. . In this way, without providing a large-sized dedicated member or dedicated equipment for the squeezing operation, the washing liquid contained in the laundry is effectively used as a component for performing the push-washing operation. Can be squeezed out.

According to a ninth aspect of the present invention, in addition to the constituent elements of the sixth to eighth aspects of the present invention, a base plate for placing an article to be washed is provided near the bottom in the washing tub. The base plate is supported on the washing tub via an elastic member, and maintains a substantially horizontal posture when no external force is applied, and is added to the laundry by the push plate. It is characterized in that it can be tilted and / or moved up and down with a change in the applied pressing force. According to the ninth aspect of the present invention described above, since the rolling force received by the elastic member changes with the change in the force of the push plate pushing down the laundry, the base plate moves with the movement of the push plate. I do. As a result, the laundry is swung in the washing water while being sandwiched between the push plate and the base plate,
The flow of the stirred washing water collides with the laundry.
The dynamic pressure generated by the collision of the washing water stream is constantly changing to promote the flow of the washing water into the laundry, thereby further improving the washing efficiency. In the case where the laundry stacked on the base plate is pressed down on the upper surface thereof by the push plate and the push plate only tilts or moves up and down, if the base plate is a stationary member, The upper laundry to be touched is strongly affected by the push washing action, but the lower washing to be in contact with the base plate, which is a stationary member, is hard to sufficiently reach the push washing action. However, if the base plate moves synchronously with the same stroke as compared with the push plate, the push washing operation is not performed. In consideration of such circumstances, since the base plate is supported by the elastic member according to the configuration of the present invention, the base plate is driven substantially synchronously with a small stroke as compared with the push plate. Both the laundry and the lower laundry
It receives a push-washing effect in almost the same way.

According to a tenth aspect of the present invention, in addition to the constituent features of the ninth aspect of the present invention, a drawer-type slider on which the object to be washed can be placed is provided on the base plate. A door is provided in the tub, and the door can be opened and the drawer-shaped slider can be pulled out at least halfway out of the washing tub so that the object to be washed can be put on or taken up therefrom.

(C), a push plate 9 supported by the push plate drive mechanism 12 via a plurality of rods 10 and an operation panel 15 provided with an automatic control device. .

The push plate drive mechanism 12 drawn by a solid line indicates a lowered position, and the push plate drive mechanism 12 'drawn by a virtual line indicates a raised position. When the push plate driving mechanism is at the raised position 12 ', the rod is moved to the raised position 1'.
0 '. As the push plate drive mechanism moves up and down, the push plate 9 supported in a suspended manner also moves up and down.
The push plate 9 can be lowered to a position where it can be in contact with the upper surface of the laundry 2 even when the laundry 2 is small. 8 is a door provided on the washing tub 7. The fact that the door is provided means that an opening is provided in the side wall of the washing tub (the side facing the front view (A), that is, the side facing the localization value of the worker), and can be opened and closed by the door 8. , Which is used for taking in and out of laundry.

FIG. 1 shows an embodiment of a water-drying type washing machine according to the present invention, and is a schematic vertical sectional view. However, since it is schematically depicted, it is not necessarily a realistic JIS projection projection. It is not a simple projection. Reference numeral 7 denotes a washing tub, which is provided with a door for taking in and out the articles to be washed as shown in FIG. 2 (A), but the door is not shown in FIG. A drain pipe 7a is provided on the bottom surface of the washing tub 7 and is provided for discharging washing water in the washing tub, and is provided with a solenoid valve (not shown). A water supply pipe 7 for supplying water to the washing tub 7 is provided.
b, and a detergent injection pipe 7c for injecting a detergent is provided, and a predetermined liquid level for washing and rinsing is set, and an overflow pipe 7d is provided for automatically maintaining this liquid level. ing.

Reference numeral 12 denotes a push plate drive mechanism described with reference to FIG. 2 described above, which is driven by a lift cylinder 14 and is moved up and down along a lift guide rail 13. The push plate drive mechanism 12 shown in FIG. 1 is located near the middle of the elevating stroke and has four rods 10a, 10a ', 10b, 10
The state where the push plate 9A supported in a suspended form by b 'is brought into contact with the upper surface of the laundry 2a is illustrated. The push plate drive mechanism 12 tilts the push plate by vertically moving the rods 10a and 10b by crank mechanisms 12a and 12b. The push plate 9A drawn by a solid line represents a state tilted to the left from the horizontal posture, and the push plate 9B drawn by a virtual line also represents a state tilted to the right. This tilt drive mechanism will be described later in detail with reference to FIG. On the bottom surface of the washing tub 7,
Is supported. In the present embodiment, it is elastically supported via the base plate support spring 17. Although the above-mentioned base plate is a constituent member for placing the laundry objects 2a and 2b, in this embodiment, the drawer type is placed on the base plate 16 without directly placing the laundry object on the base plate 16. Place the slider 21 and
The laundry 2a. 2b. With this configuration, the drawer-type slider 21 is pulled out of the washing tub 7 by opening a door (not shown) (the pull-out slider 21 may be pulled out halfway without being completely pulled out), and the laundry objects 2a and 2 can be easily drawn.
b can be loaded and unloaded in the washing tub.

It is desirable that the draw-out type slider 21 is made of a perforated plate so that washing water can flow therethrough. When the drawer type slider 21 is provided on the base plate 16, the function of the base plate 16 only needs to be supported as a rail of the drawer type slider 21. Therefore, it does not have to be plate-shaped as the name implies. When loading and unloading laundry, the lifting cylinder 14 is extended to push up the push plate drive mechanism 12, and the push plate (9A) is pulled up. The output of the lifting cylinder is adjusted in at least two stages by adjusting the pressure of the supply fluid. As shown in the figure, when the laundry 2a and 2b are pressed by the push plate 9A, and the washing or rinsing is performed by swinging in the form of repeating the left tilting posture 9A and the right tilting posture 9B, the contraction force of the lifting cylinder 14 is reduced. Adjust weakly. After the rinsing, when the lifting cylinder 14 is strongly contracted and the laundry is strongly pressed down by the push plate, the washing water contained in the laundry is squeezed out. In the present embodiment, a vinyl sheet 22, which is a water-impermeable sheet member, is sandwiched between each of the plurality of laundry objects 2a, 2b,. Accordingly, there is no possibility that color transfer will occur even if different types of laundry are put in the aqueous laundry and washed.

FIG. 3 is a schematic exploded perspective view shown to explain the structure and operation of a crank mechanism configured to alternately move two rods up and down. However, it is not a projected figure that realistically represents the apparatus of the embodiment because it is schematically drawn for explaining the principle operation. The pulley shaft 17 rotatably supports the pulleys 18a and 18b, and each pulley is rotated by a belt 19. Pulley 18a has crankpin 12c
However, a crank pin 12f is attached to the pulley 18b.

When the belt 19 rotates in the direction of arrow d to rotate the pulley 18a in the direction of arrow e, the crankpin 1
2c rotates as indicated by arrow f. This crank pin 12
c is fitted into the cam groove 12e of the cam plate 12d. The cam plate 12d is fixed to the upper end of a rod 10a supported by a slide bearing 20 so as to be slidable up and down. Thus, when the pulley 18a rotates, the rod 10
a is moved up and down. Similarly, the rod 10b is moved up and down by the rotation of the pulley 18b. 2 above
When the pulleys 18a and 18b are rotated at the same rotation speed and the phase difference between them is maintained at 180 degrees, the rod 10
a and the rod 10b alternately move up and down, and the push plate shown in FIG. 1 is repeatedly swung between the left tilting posture 9A and the right tilting posture 9B. When the push plate is swung right and left in the state where the washing tub 7 is filled with the washing liquid as described above, the distribution of the pressing force applied to the articles 2a, 2b,... Changes. In response to this, the base plate 16 also moves the solid line posture 16 and the virtual line posture 1 while alternately bending the base plate support springs 17.

Between the state of 2) and the state of (C2), the inclination direction does not change intermittently but changes continuously and continuously. When the inclination direction arrow q shown in (D) changes to the same arrow t, the state of the arrow r and the arrow s passes on the way.
That is, the inclination direction of the push plate 9 continuously changes steplessly as shown by arrows q, r, s, t, u, and v, and this change further changes as shown by the arc arrow ω. 360
It is repeated continuously in all directions. The movement as shown in FIG. 6 can be driven, for example, as follows.

FIG. 7 is a schematic perspective view showing an example of a drive mechanism for repeatedly rocking the push plate as shown in FIG. 6 described above. However, it is not a realistic projection because it is schematically illustrated for convenience of explanation of the principle. Four crank mechanisms 23a to 23d are provided, each of which is provided with a crank pin 24a to 24d and rotates at a constant speed as shown by an additional arc arrow, but has a phase difference of 90 degrees as shown in the figure. Have. That is, the phase of the crank mechanism 23b is delayed by 90 degrees as compared with the phase of the crank mechanism 23a.
One cycle later, the program returns to the crank mechanism 23a.

The movement of each of the crank pins 24a to 24d is converted into vertical movement by the cam plates 25a to 25d, and the rods 26a to 26d are moved up and down. The above-mentioned cam plate and rod are the same components as the cam plate and rod shown in FIG. 3 described above. The four rods 2
The lower ends of 6a to 26d are connected to the vicinity of the four corners of push plate 9 via ball joints. Thus, when the four crank mechanisms 23a to 23d are rotationally driven while maintaining the above-described phase relationship, the push plate 9 repeats the swing described with reference to FIG.

The laundry 2a, 2b is a push plate (9A, 9A).
In the state of being sandwiched between B) and the base plate (16, 16 '), these members swing together with the swing of these members in the washing liquid to stir the washing liquid. The agitated and flowing washing liquid collides with the laundry to be washed, thereby increasing the washing efficiency.

The push plate of the present embodiment was constituted by a perforated plate.
It is desirable that the push plate has a structure (a lattice shape, a frame shape, or the like) through which washing water can flow, and does not need to have a plate shape in appearance. When the push plate is repeatedly tilted between the left tilting posture 9A and the right tilting posture 9B as described above, the left half and the right half of the laundry 2a, 2b. And repeat this. When a part of the laundry is considered locally, it is pressed or released. The laundry to be released, which has been depressed, sucks the washing water into the inside while expanding due to the elasticity of the animal and vegetable clothing itself. When the pressing force is given, the washing water sucked is pushed out. In this way, the washing water flows to the inside of the laundry, thereby improving the effect of washing off dirt and rinsing.

As an embodiment different from the embodiment in which the push plate is tilted as described above with reference to FIG. 1, washing and rinsing can be performed by vertically moving the push plate while keeping the push plate in a substantially horizontal posture. When the push plate is moved up and down so as to move up and down in parallel, a plurality of rods 10a, 10
b are moved up and down in equal strokes in synchronization with each other. FIG. 4 is a schematic exploded perspective view for explaining an example of a crank mechanism that moves a plurality of rods up and down with an equal stroke in synchronization, and is not necessarily a realistic projection view. The pulley shaft 17 'of this embodiment is rotatably supported by bearings (not shown), and pulleys 18c and 18d are fixed to both ends thereof, and are synchronously rotated by belts 19 as indicated by arrows e and e'. A crank pin 12c fixed to the pulley 18c;
The crank pin 12c 'fixed to d is rotated synchronously, and the rod 10a and the rod 10b are vertically moved synchronously with an equal stroke.

(See FIG. 1.) When the push plate is moved up and down in a substantially horizontal position, the base plate 16 elastically supported by the plate support spring 17 also moves up and down in a substantially horizontal position.
.. Are swayed up and down in the washing water while being sandwiched between the push plate and the base plate, and the pressing force given by the push plates changes periodically. . When the pressing force decreases, the washing water infiltrates into the laundry, and when the pressing force increases, the washing water is squeezed out of the laundry, and by repeating this, the contamination adhered to the laundry. The object dissolves in the washing water and is removed.

Considering the structural functions of the water-drying type washing machine of FIG. 1 described above in comparison with the conventional washing machine shown in FIG. 5, the present invention (FIG. 1) shows a conventional example (FIG. 1). As described in 5), there is no need to provide a basket in the washing tub or a washing water jetting means, so that a large amount of laundry can be stored and washed in comparison with the inner volume of the washing tub.
In addition to being able to rinse and clean, the whole device is small, light,
It can be configured at low cost and does not need to move the basket up and down as in the conventional example (FIG. 5), so that the required power is small, and it is a large rigid member as in the conventional example (FIG. 5). Since there is no need to sandwich the spacer plate between the objects to be washed, the operation of loading and unloading the object to be washed into and out of the washing tub can be performed quickly and easily. It is possible to store and wash as much as possible of the laundry in the washing tub, and to rinse and rinse the laundry, and to squeeze the laundry using a washing and rinsing push plate.

Next, an example using the apparatus of the embodiment shown in FIG. 1 will be described in the order of steps. The operations in these steps are automatically performed by the operation panel 15 having the automatic control device shown in FIG. 2, but the door 8 shown in FIG. Preparation work for loading into the garbage and unloading work for opening the door 8 and taking out the washed laundry are manually performed by an operator. a. The lifting cylinder 14 is contracted, and the push plate drive mechanism 12 is lowered until the push plate contacts the upper surface of the laundry. At this time, it is desirable to read the volume (top height) of the article to be washed while visually checking the scale 23 shown in FIG. 1 and manually adjust the stroke of the lifting cylinder 14. b. Before, after (or concurrently with) the above-mentioned step a, water is poured into the washing tub 7 from the water supply pipe 7b, and a washing agent is injected from the detergent injection pipe 7c to form an aqueous solution for washing. Preparing (washing water) and filling the washing water to a predetermined water level; c. Crank mechanism 12a, 12b of push plate drive mechanism 12
To perform the washing operation by repeatedly tilting the push plate left and right and / or repeatedly up and down, d. Activate a solenoid valve (not shown) provided in the drain pipe 7a to drain the washed washing water (after draining, a squeezing step similar to the item h described later may be inserted) e. Supplying water from the water supply pipe 7b into the washing tub 7 and adjusting the water level by the overflow pipe 7d; f. The push plate is actuated again in the same manner as in the above item c to perform rinsing, and g. Activate the solenoid valve (not shown) in the same manner as in item d to discharge the washing water after the rinsing operation, h. The lifting cylinder 14 is strongly contracted to compress the laundry 2a, 2b with the push plate, and the washing water contained in the laundry is squeezed out.

The above-mentioned steps a to h are standard work steps, but other steps (for example, prewashing or addition of detergent) are inserted in the middle of these steps or before or after these steps. Is also possible. In a normal case, the steps a to h are automatically performed by the operation panel 15 with an automatic control device shown in FIG. 2. However, under special working conditions,

[0036]

As described above, the structure and function of the embodiment of the present invention are clarified. According to the method of the present invention, the object to be washed is pressed by the push plate in the washing liquid. Meanwhile, the distribution state of the pressing force changes periodically. For this reason, when an arbitrary part of the laundry is considered locally, the pressing force received from the pressing plate periodically changes. As a result, when the pressing force decreases, the washing liquid permeates and flows into the object to be washed, and when the pressing force increases, the soaked washing liquid flows out of the object to be washed. The washing function is performed, and contaminants adhering to the laundry are dissolved in the washing liquid and removed. Since the above operation is performed by placing the laundry in the washing tub without placing it in the basket, it is possible to put a large amount of laundry in the relatively small laundry tub and perform water-dry washing. Also, there is no need to swing the basket up and down, so less power is required. In addition, since there is no need to insert a spacer plate between the laundry items, the operation of loading the laundry item into the washing tub can be performed quickly and easily, and the washed laundry item is carried out of the washing tub. Can be performed quickly and easily.

According to the second aspect of the present invention, while the object to be washed is pressed by the push plate in the washing liquid, the magnitude of the pressing force changes periodically. For this reason, when an arbitrary portion of the laundry is considered over time, the pressing force received from the pressing plate periodically changes. As a result, when the pressing force decreases, the washing liquid permeates and flows into the object to be washed, and when the pressing force increases, the soaked washing liquid flows out of the object to be washed. The washing function is performed, and contaminants adhering to the laundry are dissolved in the washing liquid and removed. Since the above operation is performed by placing the laundry in the washing tub without placing it in the basket, it is possible to put a large amount of laundry in the relatively small laundry tub and perform water-dry washing. Also, there is no need to swing the basket up and down, so less power is required.

According to the third aspect of the present invention, when the push plate is driven to be repeatedly tilted or vertically moved up and down, the object to be washed repeatedly bends by bending the elastic member.
Or move up and down repeatedly. In this way, the washing water is repeatedly tilted or moved up and down in the washing water, whereby the washing water is agitated by the washing object, and as a result, the flow of the washing water violently collides with the washing object. , The washing effect is further enhanced.

According to the fourth aspect of the present invention, even if a plurality of types of laundry are put in a water-based washing liquid and washed with water at the same time, color transfer may occur between different types of laundry. There is no. As described above, when a plurality of objects to be washed with the possibility of color transfer mutually can be simultaneously water-dried, it goes without saying that the direct work efficiency is improved,
In the preparation for the water-dry washing, means for selecting the type of animal and plant garment according to the type thereof is omitted, and the risk of color transfer due to erroneous selection is eliminated. Under the current situation where the types of dyes and mordants are increasing due to the recent development of dyeing technology for clothing and new dyeing methods are being developed one after another, sorting work in preparation for water-dry washing is highly knowledgeable and skilled, and Since a great deal of time and labor is required, the economical effect of omitting this operation is great, and the practical value of eliminating the possibility of human error (misselection) is great.

According to the fifth aspect of the present invention, in the squeezing step after washing, large components dedicated to the squeezing operation are not required, and equipment (push plate and its driving means) for performing the washing step is not required. By using the washing water, the washing water contained in the laundry can be squeezed.

According to the apparatus of claim 6, each of the plurality of rods is moved up and down by the operation of the push plate driving mechanism, and the push plate connected to the lower ends of the plurality of rods is washed. Since the laundry is repeatedly tilted back and forth while being in contact with the upper surface of the laundry, the laundry is pushed and washed in the washing water filled in the washing tub, and the laundry can be washed without providing the washing liquid jetting means. The washing liquid flows to the inside, and contaminants dissolve in the washing liquid and are removed. The configuration of the device according to the present invention does not include a basket that stores laundry and swings up and down in the washing tub, and is directly inserted into the washing tub. Therefore, the washing tub can be made smaller and lighter than the amount of laundry to be washed in one operation. In addition, since a nozzle for injecting the washing liquid is not provided in the washing tub, the washing tub can be smaller and lighter. Further, since a pump for injecting the washing liquid and a driving mechanism thereof are not required, the entire apparatus is small, light and inexpensive. In addition, since a spacer plate, which is a large member having rigidity, is not required, handling is easy, and there is no dead space occupied by the spacer plate. You can put it inside and wash it with water.

According to the seventh aspect of the present invention, each of the plurality of rods is moved up and down by the operation of the push plate driving mechanism, and the push plate connected to the lower ends of the plurality of rods is washed. Since the object is repeatedly moved up and down while being in contact with the upper surface of the object, the object to be washed is pushed and washed in the washing water filled in the washing tub, and the object to be washed without the washing liquid jetting means is provided. The washing liquid flows to the inside, and contaminants dissolve in the washing liquid and are removed. The configuration of the device according to the present invention does not include a basket that stores laundry and swings up and down in the washing tub, and is directly inserted into the washing tub. Therefore, the washing tub can be made smaller and lighter than the amount of laundry to be washed in one operation. In addition, since a nozzle for injecting the washing liquid is not provided in the washing tub, the washing tub can be smaller and lighter. Further, since a pump for injecting the washing liquid and a driving mechanism thereof are not required, the entire apparatus is small, light and inexpensive. In addition, since a spacer plate, which is a large member having rigidity, is not required, handling is easy, and there is no dead space occupied by the spacer plate. You can put it inside and wash it with water.

According to the present invention, the push plate drive mechanism for supporting the push plate in a suspended manner is guided above the washing tub so as to be able to move up and down, and the up and down movement is driven by the cylinder means. Because, when the push plate drive mechanism is raised, the push plate is pulled up,
The operation of taking in and out the laundry to be washed into the washing tub can be freely performed. Further, when the push plate driving mechanism is lowered, the push plate is lowered and comes into contact with the laundry to be able to perform the push washing action. Further, when the push plate driving mechanism is lowered with a strong force in a state where the washing water in the washing tub is drained and the inside of the tub is emptied, the push plate strongly presses down the laundry to perform the squeezing operation. . In this way, without providing a large-sized dedicated member or dedicated equipment for the squeezing operation, the washing liquid contained in the laundry is effectively used as a component for performing the push-washing operation. Can be squeezed out.

According to the ninth aspect of the present invention, since the pressing force applied to the elastic member changes with the change in the force of the push plate pressing down the laundry, the base plate moves with the movement of the push plate. . As a result, the laundry is swung in the washing water while being sandwiched between the push plate and the base plate, and the flow of the stirred washing water collides with the laundry. The dynamic pressure generated by the collision of the washing water stream is constantly changing to promote the flow of the washing water into the laundry, thereby further improving the washing efficiency. The laundry to be stacked on the base plate,
In the case where the push plate only tilts or moves up and down while the upper surface thereof is being pressed down by the push plate, if the base plate is a stationary member, the upper-layer laundry to be in contact with the push plate has a push-washing action. However, it is difficult for the washing action to sufficiently reach the lower laundry to be in contact with the base plate, which is a stationary member. However, if the base plate moves synchronously with the same stroke as compared with the push plate, the push washing operation is not performed.
In consideration of such circumstances, since the base plate is supported by the elastic member according to the configuration of the present invention, the base plate is driven substantially synchronously with a small stroke as compared with the push plate. The laundry to be washed and the laundry to be washed in the lower layer are almost similarly subjected to a push-washing action.

According to the tenth aspect of the present invention, since the laundry is placed on the drawer-type slider provided on the base plate, the door is opened to open the drawer-type slider. Preparation of washing operation by quickly and easily positioning the laundry on the base plate by pulling out the slider, placing the laundry on the slider, pushing the slider into the washing tub and closing the door Is performed. Similarly, after the washing operation (rinsing and squeezing) is completed, the laundry is located on the base plate in the washing tub, but by opening the door and pulling out the slider, the laundry to be washed is completed. The object can be quickly and easily picked up, and after picking up the washed laundry, the laundry of the next work cycle can be placed on the slider as it is, and the water-dry washing operation can be performed. The overall work efficiency can be improved.

According to the eleventh aspect of the present invention, the washing, rinsing, and squeezing operations can be automatically performed by the water-dry washing method, and there is no risk of a human operation error.
