Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine for washing laundry using vibration waves.

[0002]

2. Description of the Related Art Laundry (water, water, etc.) is used for washing laundry (clothing, textiles, carpets, futons, cotton, wool, synthetic fibers, etc.).
A method of giving a vortex to a washing water, a soap solution, a detergent aqueous solution, a solvent, etc.) and agitating or reversible vortex agitating to wash is widely used. A washing machine using a vibration wave has also been invented, as disclosed in Japanese Patent Application No. 8-14897.

[0003]

In the conventional washing by vortex agitation, the laundry is entangled with each other and the laundry is easily damaged. There is a disadvantage that it has to be loosened one by one. As a method for solving this problem, a washing machine using a vibration wave disclosed in Japanese Patent Application No. 8-214797 has been invented, but it has been difficult to perform both washing and dehydration in one washing tub. The present invention has been made to eliminate these disadvantages.

[0004]

According to the present invention, in order to solve these problems, an object to be washed (7) is placed in a dewatering basket (6) having a large opening ratio, and The vibration wave generated by the vibration wave generator (15) installed outside or the vibration wave generator (26) having the elastic vibrating plate (23) is efficiently applied to the laundry (7), and the laundry is washed. After that, the washing liquid (8) is drained, and the dewatering basket (6) is rotated as it is to be dewatered.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION When a washing liquid is put in a washing tub, a washing object is put in a dehydrating basket, and a vibration wave is generated by a vibration wave generator, the washing liquid and the washing object are rapidly increased. Since the vibration is repeated, a washing effect can be obtained, washing can be performed by rotating the dewatering basket after draining, and an effect can be obtained that the articles to be washed are not entangled with each other.

[0006]

Embodiments of the present invention will be described below. FIG.
FIG. 2 is a plan sectional view of the washing machine according to the present invention, and FIG. 2 is a side sectional view. The vibration wave generator (15) comprises a driving device (1), a main shaft (2), and a plurality of diaphragms (3) fixed to the main shaft (2), and a gantry (5) fixed to a washing tub (4). ) Is fixed. The main shaft (2) is guided by a guide (21) and a guide (22) and has a structure in which a reciprocating motion is smoothly performed. A dehydrating basket (6) for dehydrating the laundry (7) is provided. The dehydrating basket (6) is connected to a pulley (10), a V-belt (11) and a pulley (12) by a motor (9). The rotation device is configured to be rotated by a drive device (13) for rotating the dehydrating basket through the intermediary. Although not shown in the drawing, the dehydrating basket rotating drive device (13) includes a brake and a structure capable of controlling the rotating force. Further, although not shown in the drawings, a water supply port is provided at the top of the washing tub (4), and a drain port is provided at the bottom of the washing tub (4). Although not shown in the drawing, the washing tub (4) and the dehydrating device are attached to the outer box (14) by a suspension rod via a buffer such as a spring. In order to efficiently supply the vibration wave generated by the vibration wave generator (15) to the object to be washed (7), the dewatering basket (6) has a hole opening ratio within the allowable range of the strength of the dewatering basket (6). It is preferable to make the structure larger. For example, FIG. 3 is an example of a development view in which square holes are arranged on the surface of the dehydrating basket (6).
When the grid is wide, the aperture ratio is about 39%. However, if the lattice width is widened due to the strength of the dewatering basket (6), the aperture ratio cannot be reduced. FIG. 4 is an example of a development view in which round holes are arranged on the surface of the dehydrating basket (6).
When staggered at a pitch of 0 mm, the aperture ratio becomes about 39%. However, if the pitch is increased due to the strength of the dewatering basket (6), the aperture ratio is inevitably reduced. When the thickness is reduced, the pitch of the holes must be increased, and the porosity decreases. However, it is preferable that the porosity be about 30% or more. Since the vibration wave is also a kind of sound wave, it propagates through the washing liquid (8) in the washing tub (4), and
The vibration wave of the washing liquid (8) in the washing tub (4) propagates in all directions because the vibration wave is reflected on the surface of the dehydrating basket (6). Therefore, as shown in FIG. 1, FIG. 2, FIG. 7, FIG. 8, and FIG. 9, not only the vibration wave from the vibration wave generator (15) side but inside the dewatering basket (6) from all directions. Energy efficiency is high because vibration waves propagate. The washing liquid (8) not only vibrates due to the vibration wave but also the vibration wave generated by the vibration wave generator (15) hits the surface of the washing tub (4), the dehydrating basket (6), etc., and the washing liquid (8). Then, a flow is caused to flow, and an action of flowing the foreign matter (18) or the product (19) of the dirt released from the laundry (7) occurs. FIG. 5 shows a washing mechanism of the vortex washing machine, and FIG. 6 shows a washing mechanism of the vibration wave washing machine. In FIG. 5, the fibrous layer (16) having a thickness of 1 is composed of many fibers (17), and when the foreign matter (18) is between the fibers (17), focusing on an arbitrary molecule (20) of the washing liquid, Vortex or centrifugal force causes the fiber layer (16) to return in one direction,
Foreign substances (18) and products (19) are released from the inside of the fiber layer (16) to the outside. In this case, for example, if the position of the foreign matter (18) or the product (19) is entangled with the fibers (17) in the direction in which the washing liquid (8) flows, the fibers cannot be released to the outside of the fiber layer (16), and When the liquid (8) flows in the opposite direction, it is discharged outside the fiber layer (16). In the vortex-type washing machine, a vortex is given to the washing liquid (8) to give a rotating motion to the washing liquid (8) and the article to be washed (7), or the direction of the vortex is periodically reversed to wash the washing liquid (8). Since the washing is performed while giving a relative speed between (8) and the laundry (7), an undesirable phenomenon that the laundry (7) is entangled with each other during rotation and reverse rotation has occurred. As shown in FIG. 6, the washing mechanism of the vibration wave type washing machine is an arbitrary molecule (20) of the washing liquid (8).
Repeats reciprocating motion according to the period of the vibration wave, for example,
Since the vibration wave of about 3 to 60 Hz can be given, the foreign matter (18) and the product (19) are quickly released from the inside of the fiber layer (16) to the outside, so that the time required for washing is short. There are advantages. In the case of washing with water, the washing liquid (8) having a high detergent concentration in the fiber layer (16) is discharged to the outside, and water having a low detergent concentration is replaced in the fiber layer,
Washing is performed. FIG. 7 shows a side cross-sectional view when two vibration wave generators (15) are used, and FIG. 8 shows four vibration wave generators (15) installed at four corners of the washing tub (4). FIG. 9 shows a plan sectional view of the example, and FIG. 9 shows a side sectional view thereof. As described above, various shapes are used for the number of the vibration wave generators (15) and the shape of the vibration plate (3), and the shapes are not limited to those shown in FIGS. 1, 2, 7, 8, and 9. Absent. As shown in FIG. 10, the vibration wave generator (15) includes a driving device (1), a main shaft (2), and a plurality of diaphragms (3) fixed to the main shaft (2). The reciprocating motion is performed in the axial direction 2). Also, a vibration wave generator (2) having a structure in which the elastic vibration plate (23) is fixed to a fixing plate (24) fixed to the main shaft (2) with a fastener (25) such as a rivet.
6) That is, as shown in FIG. 11, the elastic diaphragm (23)
The structure of the vibration wave generator (26) having the following may be adopted, and the structure of the vibration wave generator is not limited to the structures shown in FIGS. Furthermore, the mounting direction of the main shaft (2) of the vibration wave generator is not necessarily limited to the vertical direction, but may be mounted horizontally or inclined. In addition, a pulsator for causing vortexing of the washing liquid (8) may be provided at the bottom of the dewatering basket (6), similarly to the vortex stirring type washing machine widely used at present. If the pulsator for stirring is used, since the laundry (7) is entangled with each other, the laundry (7) must be loosened by hand before drying. The dewatering basket (6) of which the opening rate of the surface of the dewatering basket (6) of the machine is about 30% or more.
A vibration wave generator (15) or a vibration wave generator (26) having an elastic vibrating plate (23) is provided outside, and is switched between a case of performing a vibration wave type washing and a case of performing a vortex-type stirring type washing. Can also be used. Of course, it is also possible to use the vortex stirring pulsator and the vibration wave generator at the same time.
