Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic washing machine for washing large clothes using a washing net.

2. Description of the Related Art In recent years, washing machines, especially fully automatic washing machines, have become larger, and it has become possible to wash large clothes such as skin blankets and blankets at home. In such a case, it is a general washing method to wash the skin blanket or blanket as it is in a washing tub or to use a dedicated washing net. The structure of a conventional laundry net when a dedicated laundry net is used will be described with reference to FIGS. 6 and 7. The laundry net 1 is provided with an opening / closing fastener 4 in an arc shape on the upper side portion 2 or on the upper surface portion 3. ,
It has a substantially cylindrical shape made of a net-like cloth, and has a shape along the washing tub 6 when the skin blanket and the blanket 5 are stored. Therefore, the clothes move smoothly left and right according to the rotation of the pulsator 7 during washing and rinsing. Since the water flowing from the circulating lint filter 8 sufficiently scatters above the skin blanket and the blanket 5, washing and rinsing can be performed evenly.

Problems to be Solved by the Invention However, in the conventional configuration, since the upper surface portion 3 is a net-like fabric, the detergent water coming out of the circulating lint filter 8 directly flows over the skin blanket and the blanket 5. Since the washing net 1 is substantially cylindrical and extends along the washing tub 6,
The laundry net 1 containing the skin blanket and the blanket 5 rotates only in the horizontal direction and does not rotate up and down. Therefore, there is a problem that the particles of the powder detergent adhere to the surface of the skin blanket or the blanket 5 and remain after washing. Therefore, an attempt was made to make the upper surface cloth 3 a cloth that does not allow particles of the powdered detergent to pass through, such as cotton cloth. Comes out and the washing net 1 rises and gets stuck on the lower end of the fluid balancer 9, so that the washing net 1 does not move smoothly and the detergent on the upper part is immediately washed down from the side, so that the upper part of the clothes is well There was a problem that it could not be washed.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to make it possible to wash large clothing such as skin bedding.

Means for Solving the Problems In order to achieve the above object, the present invention relates to a substantially cylindrical laundry net, which is made of a cloth having a water-permeable upper surface and impervious to powder detergent particles. The upper fabric with a small hole for venting the air and the upper fabric with the upper net fabric larger than the upper fabric at the top, wash with a large-size washing automatic course, and during the rinsing process of the course, to the high water level After the water supply, the operation is stopped for a certain short period of time, followed by stirring and rinsing.

Action According to the above configuration, the particles of the powder detergent do not adhere to and remain on the surface of the skin budding, etc., and the laundry net is lifted by the air coming out of the clothing such as the skin budding, and the fluid balancer It is possible to prevent large clothes from being stuck and to be able to wash properly.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view of a fully automatic washing machine, and FIG. 2 is an example of a block diagram of a control device.

In FIG. 2, reference numeral 10 denotes a washing and dewatering tub, and a pulsator 11 is rotatably arranged at the center bottom. Reference numeral 12 denotes a water tank containing a washing and dewatering tub. A substrate 13 is fixed to the outer bottom of the water tub 12, and a drive motor 14, a drainage electromagnetic valve 15, a washing and dewatering switching mechanism 16 and the like are provided. The outer edge of the substrate 13 is suspended from the upper corner of the outer frame 19 via a vibration isolator 17 and another rod 18. An upper cover 20 is provided above the outer frame 19, and a water supply valve 21, a power switch 22, a control device 23, and the like are provided. The control device 23 includes the motor 14, the drain solenoid valve 15,
The water supply valve 23 and the like are controlled.

A fluid balancer 24 is fixed to an upper portion of the washing and dewatering tub 10, and a circulating lint filter 25 is provided on a part of the fluid balancer 24, and communicates with a water channel 26 formed on a side wall of the washing and dewatering tub 10. .

A clothing inlet 27 is formed in the center of the upper cover 20, and a lid 28 is provided to be freely opened and closed. 29 is an operation panel.

Reference numeral 30 denotes a substantially cylindrical washing net which is put into the washing / dewatering tub 10 for washing large clothing such as skin bedding, which will be described later in detail.

Next, in FIG. 1, 31 is an AC power supply, and 32 is a motor.
14 phase-advancing capacitors. The control device 23 is housed in a signal control means 33 composed of a microcomputer and an operation panel 29, and a program is set in advance. Automatic course changeover switch 34 including large washing course, start / pause switch 3 for both start and pause
5, an operation display means 37 comprising a display device 36, and a motor 14, a drain solenoid valve 15, a water supply valve according to a signal from the signal control means 33.
It is composed of a power switching means 38 for controlling 21 and the like, a water level detecting means 39, and a storage means 40.

3 and 4 are perspective views of the washing net 30. The washing net 30 is substantially cylindrical and the whole is made of a net-like cloth. Reference numeral 41 denotes an upper surface cloth, which is water-permeable and impervious to powder detergent particles. Reference numeral 42 denotes the side surface fabric, which is sewn so that the fabric extends in the vertical direction, and 43 denotes the lower surface fabric. A fastener 44 for opening and closing the net is provided at a boundary between the upper surface cloth 41 and the side cloth 42. An air vent small hole 45 is provided in the center of the upper surface fabric 41. An upper surface net fabric 46 having a larger mesh than the upper surface material is provided above the upper surface material 41.
In this configuration, the quilt or blanket is folded in four or five.
When folded and wound, the washing net 30 can easily maintain its cylindrical shape, which is more effective. After putting the skin bedding, etc., the zipper 44 is closed, and the washing net 30 is put in advance into the washing / dehydrating phase 10 containing the detergent so that the zipper 44 is on the top. At this time, since the upper and lower surface diameters of the washing net 30 are slightly larger than the clothes inlet 27, the washing net 30 is pushed into the washing and spin-drying tub 10 from above by hand.

FIG. 5 shows an embodiment of the flowchart of the present invention.
When the power switch 22 is turned on, the program starts, and after a key input of 101, it is determined at 102 whether or not the course is a large washing course. If it is a large washing course, water is supplied to a high water level at 103 and washing and stirring are started at 104. At this time,
Since the diameter of the washing net 30 is slightly smaller than the diameter of the washing and dewatering tub 10, it does not irregularly hit the washing and dewatering tub 10,
Rotate left and right very smoothly. In addition, the height of the washing net 30 is smaller than the height from the bottom of the washing and dewatering tub 10 to the lower surface of the fluid balancer 24, so that the washing net 30 can sufficiently fall within the specified water level.
Then, the detergent water pumped up by the rotation of the pulsator 11 passes through the circulating lint filter 25, and enters a state in which the detergent water sufficiently covers the washing net 30 from above. At this time, since the upper surface fabric 41 of the washing net 30 is a cloth having water permeability and impervious to the particles of the powder detergent, the particles of the powder detergent that do not completely dissolve are washed out of the washing net 30. It does not adhere to the surface of tons or blankets.

After the washing, draining is performed at 105 and intermediate dehydration is performed at 106.
Next, the rinsing process is started, and water is supplied to a high water level at 107.
At this time, the skin bedding in the washing net 30 gradually rises as the amount of supplied water increases due to the buoyancy due to the dehydration of 106, because it contains a lot of air, and hits the lower end of the fluid balancer 24, With the force of pushing up, the top of the skin cushion may even bulge into the inner diameter of the fluid balancer 24. However, after the end of water supply 108
And stop for 10 seconds. Then the upper fabric of the washing net 30
The air escapes from the air vent small hole 45 provided in 41,
The skin bedding will wither. Small hole 45 for venting the water
Air cannot escape because water is flowing over the water. Then, the stirring is started at 109. At this time, the air of the skin budding is evacuated, and the laundry net 30 can be rotated left and right extremely smoothly right and left. Next, at 110, the water supply valve 21 is operated again, and at 111, water rinsing is sufficiently performed. At this time, since water has infiltrated after the air has escaped, it does not float. Drainage and dehydration are performed at 112 and 113, and the washing is completed.

Advantageous Effects of the Invention As described above, according to the present invention, even if skin bedding stored in a washing net contains air due to dehydration and rises by supplying water in a rinsing step, the air escapes and the washing net Is extremely smoothly inverted right and left without losing the rinsing performance.
