Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a washing method using a dehydrator capable of carrying out washing and dehydration of laundry items stored in a dehydration basket.

[Technical background of the invention]

When washing in a two-tub washing machine, regardless of the size of the laundry, first wash and rinse the laundry in the washing tub, then transfer it to the spin basket. I try to dehydrate.

[Problems with background technology]

However, in the case of blankets and the like, there is a problem in that during washing in the washing tub, they are rolled up and cannot be loosened easily, resulting in insufficient stirring and uneven washing. In addition, blankets are relatively light at about 2 kg when dry, but weigh about 10 kg when wet, and when transferred from the washing tub to the dehydration basket, they absorb the water and become heavier. I had to lift the blanket,
There was a problem that housewives had to work hard.

[Purpose of the invention]

The present invention was made in view of the above circumstances, and
Its purpose is to eliminate the need to handle laundry items such as blankets while they contain large amounts of water, and to be able to wash the entire item cleanly without causing uneven washing, and to do the entire process from washing to spin-drying continuously. To provide a washing method using a dehydrator that can be carried out.

[Summary of the invention]

The present invention provides a water sprinkling tube that stands upright in a dewatering basket, a storage section in a water supply channel for supplying water from a water source into the water sprinkling tube, and a blanket or the like in the space surrounding the water sprinkling tube in the dehydrating basket. A long item to be washed is stored and arranged in a rolled-up state, and the detergent supplied to the storage section is gradually flowed out into the water supply channel, while water from the water source is passed through the water supply channel into the water spray tube. By intermittently driving the dehydration basket while supplying detergent to the laundry, water containing detergent is supplied from the water spray tube to the laundry to obtain a washing action, and when the detergent is exhausted from the storage section, the dehydration basket is intermittently driven. The laundry items are rinsed with water supplied from the water supply channel to the laundry items through a water spray pipe, and after this rinsing, the dehydration basket is continuously driven with the water supply cut off from the water source. This method eliminates the need to transfer the laundry items to a dehydration basket after washing, and allows water containing detergent to permeate the entire laundry item evenly and wash the entire item without causing uneven washing. The purpose is to allow cleaning to be done thoroughly and also to be able to perform a series of continuous operations from washing to dehydration.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

First, in FIG. 1, reference numeral 1 denotes an outer box of a two-tub washing machine. Inside this outer box 1, a washing tub 2 and a dewatering tank 3 are arranged side by side. At the inner bottom of the washing tub 2, a washing motor 4 is driven. A stirring blade 5 is provided. Further, a dewatering basket 7 driven by a dehydrating motor 6 is disposed in the dehydrating receiving tank 3, and a water sprinkling tube 8 is erected in the center of the dehydrating basket 7. Of the inner cover 10 and outer cover 11 for opening and closing the laundry entrance/exit 9 to the dehydration basket 7, a water injector 12 for injecting water into the water spray cylinder 8 is attached to the lower surface of the inner cover 10. The water spray tube 8 is made of sintered resin, for example, and is integrally molded with numerous water-permeable micropores in the wall. Good too. On the other hand, reference numeral 13 denotes an operation box erected at the rear of the upper part of the outer box 1, and this operation box 13 includes a washing timer 14, a dehydration timer 15, etc., as well as a water supply solenoid valve 16 and a lever 17. By switching the switch 18, the tap water supplied from the electromagnetic valve 16 is passed through the washing side waterway 19 or the dewatering side waterway 20 as a supply waterway. It is configured so that it can be selectively supplied to the washing tub 2 or the water injector 12. Further, as shown in FIG. 2, the front surface of the operation box 13 is provided with a detergent input portion 21, while a container-shaped guide portion 22 is recessed at the bottom of the operation box 13.
An outlet 21 a of the input section 21 faces inside this guide section 22 . In addition, in Figures 2 and 3, 23
is a storage section, which is integrally formed on the outside of one side wall 20a of the dewatering water channel 20 so as to include the outlet 22a of the guide section 22 and located directly below it; Dewatering side waterway 2
0 and two slits 2 formed in the side wall 20a.
4 and 25.

The electrical circuit configuration on the dehydrator side will be explained with reference to FIG. 4. Reference numeral 26 is a lid switch that closes when the outer lid 11 is closed, 27 is a buzzer, and 28 is linked to switching of the knob 18 by the lever 17. This is a water injection switch that changes when the water is turned on. On the other hand, the dehydration timer 15 includes a timer motor 29 and a plurality of cam switches 30 to 33 that are opened and closed by a group of cams using the timer motor 29 as a driving source, and includes the dehydration motor 6, the water supply solenoid valve 16, The buzzer 27 and the switches 26 and 28 are connected as shown in FIG. Each of the cam switches 30 to 33 of the dewatering timer 15 opens and closes as shown in FIG. 5, and the hatched portion indicates the closing period. That is, the dehydration timer 15 is set to 34 in FIG.
"Wash", "Dehydration Rinse" as shown by the rotation position of
and "dehydration" are set to proceed in order. Then, the cam switch 33 alternately closes for 1 minute and opens for 1 minute during the "wash" process set for 4 minutes and the "dehydration rinse" process set for 9 minutes, and then closes for 1 minute and opens for 1 minute. The closed state is maintained during the set "dehydration" process.

By the way, when the water injection changeover switch 28 is set to close between the contacts (c and b), the water supply solenoid valve 16 can be manually controlled to be energized or disconnected when water is supplied to the washing tub 2. Further, 35 is an AC power source.

Next, in the above configuration, a case where a long object to be washed, such as a blanket, is washed will be explained. First, the blanket 36 is folded to have a width equivalent to the length of the water spray tube 8, and then wound into a spiral to form a tube. Then, the blanket 36 rolled into a cylinder is placed in the water spray tube 8 inside the dehydration basket 7.
(See Figure 1). The inner cover 10 and outer cover 11 are closed (lid switch 26 is closed), and the lever 17 is used to set the pot 18 to the water supply side of the water injector 12 (closed between contacts (c and a) of the water injector switch 28. ).
Then, a predetermined amount of liquid detergent is poured into the input portion 21 of the operation box 13, and the knob 34 of the dehydration timer 15 is operated to set the start point of the "washing" process. As a result, cam switches 30, 32 and 33
is closed, the timer motor 29 is energized to start a timed operation, and the water supply solenoid valve 16 and the dewatering motor 6 are energized.

By the way, the detergent introduced into the input section 21 is dripped and stored in the storage section 23 via the guide section 22. At the same time, water from the water supply solenoid valve 16 flows out in the dewatering side waterway 20 in the direction of arrow A in FIG. The water enters the storage section 23 through the slit 24 on the upstream side, and the water enters the storage section 23.
The water mixes with the detergent contained in the water, gradually flows out from the slit 25 on the downstream side into the dewatering side waterway 20, and gradually dissolves into the water flowing inside the waterway 20. Therefore,
The water flowing in the dewatering water channel 20 finally becomes water containing detergent and is injected into the water spray tube 8 from the water injector 12. Now, when the dehydration motor 6 is energized as described above, the dehydration basket 7 is driven and its rotational speed is gradually increased, so that the water injected into the water spray tube 8 is affected by its water head and rotational centrifugal force. Water is vigorously jetted out from the permeable micropores in the peripheral wall toward the surrounding blanket 36, and the blanket 3
6 and is discharged into the dehydration receiving tank 3. Water is poured into the water spray cylinder 8 without interruption by keeping the cam switch 30 closed during the "washing" process and continuing to energize the water supply solenoid valve 16.
On the other hand, in the dehydration basket 7, the dehydration motor 6 is connected to the cam switch 3.
3, the power is alternately turned on and off at one-minute intervals, so
Drive rotation and inertia rotation are repeated every minute, and the rotation speed is approximately
It rises to 1300r.pm and approximately 200rpm during each coasting rotation.
pm (the rotation mode of this dehydration basket 7 is shown in FIG. 7). As described above, since the rotational speed of the dehydration basket 7 repeatedly increases and decreases during the "washing" process, the speed of water passing through the blanket 36 decreases in the low rotational speed range, and the water permeates the blanket 36 evenly. In the high-speed rotation range, the speed of water passing through the blanket 36 increases, and the permeated water is actively shaken off. By repeating such water infiltration and shaking off, the detergent-containing water comes to pass through the blanket 36 in a centrifugal direction while coming into contact with the blanket 36, and is therefore agitated in the washing tub 2. Water containing detergent and a blanket 36 as in the case of washing the wings 5 by rotating them.
The blankets 36 are brought into contact with each other and move relative to each other, thereby obtaining a cleaning action and washing the blanket 36. Since water is ejected almost evenly from the entire circumference of the water spray tube 8, the blanket 3 stored in the surrounding space
6, the water penetrates evenly throughout the product, so it can be washed evenly without causing uneven washing.

Now, when the above-mentioned "washing" process is carried out for about 4 minutes, the detergent in the reservoir 23 that had been flowing out little by little into the dehydration side waterway 20 disappears, and the detergent is contained in the water spray tube 8. The process moves to a "dehydration rinsing" process in which the dehydration basket 7 is alternately driven and rotated at one-minute intervals while supplying clean water. In this "dehydration rinsing" process, fresh water is spouted from the water spray barrel 8, passes through the blanket 36 by centrifugal dehydration action, and is discharged into the dehydration receiving tank 3 together with detergent, thereby rinsing the blanket 36. be exposed. When the "dewatering and rinsing" process is completed and the process moves to the "dewatering" process, the cam switch 30 opens and the water supply solenoid valve 16 is cut off, so water injection into the water spray tube 8 is stopped and the cam switch 33 is activated. In order to continue the final closed state in the ``dehydration and rinsing'' process, the dehydration motor 6 is continuously energized, and thereby the dehydration basket 7 is continuously driven to perform the ``dehydration and rinsing'' process.
It rotates at a higher speed than the maximum rotation of the stroke (see FIG. 7), thereby performing dehydration in which water is shaken off and removed from the blanket 36. Then, at the end of the "dehydration" process, the cam switch 31 closes and the buzzer 27 sounds, and then all the cam switches 30 to 33
is turned off, and the operation ends.

Note that a "dehydration" process may be provided between the "washing" process and the "dehydration rinsing" process, in which the dehydration basket 7 is driven to rotate without supplying water to the water spray cylinder 8. Further, in the above embodiment, both the "washing" and "dehydration rinsing" processes are set in the same operating mode in which the dehydrating motor 6 is alternately opened and closed at one-minute intervals, but they may be in different operating modes.

Next, FIGS. 8 to 12 show other embodiments of the present invention, and the difference from the above embodiment is that finishing treatment is performed on the dehydrator side to attach a soft finishing agent etc. to the laundry items. It was made so that it could be done. Hereinafter, in FIGS. 8 to 12, the same parts as in the above-mentioned embodiment will be denoted by the same reference numerals, and different parts will be explained. First, in FIG. 8, reference numeral 37 denotes a finishing agent inputting section, which is located below the detergent loading section 21 on the front surface of the operation box 13 and is formed separately from the detergent loading section 21. Reference numeral 38 denotes a finishing agent guide section, which is located at the bottom of the operation box 13 in front of the detergent guide section 22.
It is formed separately from 2. The reason why the finishing agent input section 37 and the guide section 38 are divided into the detergent input section 21 and the guide section 22 is that the soft finishing agent is usually composed of a cationic surfactant and the anionic surfactant. This is because if it mixes with the constituent detergent, its finishing effect will be impaired.
Next, in FIG. 9 showing the electric circuit, 39 and 4
0 is a cam switch of the dehydration timer 15, which is provided in place of the cam switch 33 in the previous embodiment, and is opened and closed together with the other cam switches 30, 31, and 32 as shown in FIG. The shaded area indicates the closing period. That is, the dehydration timer 15 has two operating bands, which, when expressed as one rotation of the knob 34 as shown in FIG. It is divided into an operating zone indicated by the angular range D, and the operating zone C consists of the "washing" process, the "dehydration rinsing" process, and the "dehydration" process similar to the one embodiment described above, and the D operating band consists of the "dewatering" process. It consists of a "finishing" process and a "dehydration" process immediately thereafter. The cam switch 39 is then alternately closed for 3 seconds and opened for 6 seconds, for example, during the entire period of both operation bands C and D. In addition, the cam switch 40 is operated for one minute during the "washing" process and the "dehydrating and rinsing" process.
b) The state in which the space is closed and the 1 minute contact piece c is the contact piece a,
In the "finishing" step, which is set for 4 minutes, the closed state is alternately repeated with no connection to any of b), and in the "finishing" process set for 4 minutes, the state is closed for the first 3 minutes of the segment (c-a), and the second half is in the closed state for 1 minute. The state between the intermediate pieces (c and b) is changed to closed, and the closed state between the intermediate pieces (c and b) is maintained during both "dehydration" steps, both of which are set for 3 minutes. Therefore, "washing" in the C operating band,
A series of operations of "dehydration rinsing" and "dehydration" are performed in the same mode as in the previous embodiment (see FIG. 12).

Next, in the above configuration, the effect when a soft finishing agent is applied to the blanket 36 after dehydration and rinsing will be described. That is, a predetermined amount of the soft finishing agent is poured into the lower input portion 37, and the knob 34 of the dehydration timer 15 is operated to set the start point of the "finishing" process. As a result, the cam switches 30 and 32 are closed, and the cam switch 40 closes the contact piece (c-b). At this time, the lid switch 26 is in the closed state, and the water filling changeover switch 28 is also in the state where the contacts (ca) are closed, so the timer motor 29 is energized and starts a timed operation. Water supply solenoid valve 16 and dewatering motor 6
is energized.

By the way, the finishing agent introduced into the input section 37 is dripped and stored in the storage section 23 via the guide section 38. Note that the detergent remaining in the reservoir 23 during the previous washing process is cleaned in the subsequent dewatering and rinsing process, so there is no risk of impairing the effectiveness of the finishing agent.
At the same time, water supply solenoid valve 1
As explained in the previous embodiment, the water from 6 flows out in the direction of arrow A in FIG. The water enters the storage section 23 through the slit 24 on the side, mixes with the finishing agent in the storage section 23, and gradually flows out through the slit 25 on the downstream side into the dewatering side waterway 20 and flows within the waterway 20. It begins to dissolve in water. Therefore, the dewatering side waterway 2
The water flowing through the water bottle 0 finally becomes water containing a finishing agent and is injected into the water spray tube 8 from the water injector 12. On the other hand, since the dewatering motor 6 is turned on and off by the cam switch 39, which repeats opening and closing, the dewatering basket 7 is
The dewatering basket 7 is driven to rotate by the second dewatering motor 6 and is intermittently driven by inert rotation for 6 seconds, and although the dehydrating basket 7 gradually increases its rotational speed due to this intermittent drive, the increase is gradual and not that much. As a result, the average rotational speed of the dewatering basket 7 during the "finishing" process is approximately 200 r.
pm) is lower than the average rotational speed (about 800 rpm) in the "washing" process and the "dehydrating and rinsing" process (see Figure 12). The water containing the finishing agent injected into the water spray barrel 8 is ejected toward the blanket 36 due to its water head and rotational centrifugal force, passes through the blanket 36, and finally enters the dewatering tank 3.
released within. At this time, as mentioned above, the dehydration basket 7 is rotating at a lower speed than during dehydration rinsing, so the water containing the finishing agent does not pass through the blanket 36 all at once, and is distributed evenly over the blanket 36. An ideal condition for the adhesion of the finishing agent, in which the finishing agent impinges on the blanket 36 while permeating, is achieved, and the finishing agent can be effectively deposited on the blanket 36. When such an intermittent driving operation of the dewatering basket 7 is performed for 3 minutes, the cam switch 40 switches from closing between the contact pieces (ca) to closing between the contact pieces (c and b), so that the dehydration motor 6 is continuously energized for the remaining one minute of the "finishing" process, and as a result, the rotational speed of the dewatering basket 7 increases significantly (see FIG. 12). Now, when the "finishing" process is completed and the transition to the "dewatering" process begins (the finishing agent in the reservoir 23 is exhausted at or slightly before the end of the "finishing" process), the cam switch 30 opens and the water supply starts. In order to cut off the power to the electromagnetic valve 16, the water injection into the water spray tube 8 is stopped, and the cam switch 40 is turned off when the contact piece (c-
b) In order to maintain the closed state, the dehydration motor 6 is continuously energized, and as a result, the dehydration basket 7 continues to increase its rotational speed and enters a high-speed rotation state.
The blanket 36 is dehydrated. Of course, in this case, the finishing agent that once adhered to the blanket 36 in the previous "finishing" step does not come off due to the dehydration effect, and only the moisture is mainly shaken off.

In each of the embodiments described above, the dewatering side waterway 20 and the storage section 23 are connected by two slits 2.
4 and 25, but this may be done only through the slit 24 on the upstream side as shown in FIG. Since the water enters into the storage section 23 and flows out, the same effect can be obtained. Further, when washing ordinary laundry such as clothes, the clothes may be washed in the washing tub 2, and then transferred to the dehydration basket 7 for dehydration rinsing and dehydration.

Furthermore, the present invention is not limited to the embodiments described above and shown in the drawings; for example, the shape of the blanket may be arbitrary as long as it is housed in a cylindrical shape; It can be widely applied to washing not only long items such as duvet covers, but also general items such as sheets.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, even long laundry items such as blankets can be stored and washed in a dehydration basket. Therefore, unlike when washing in a washing tub, there is no need to transfer the laundry, which contains a large amount of water and is quite heavy, from the washing tub to the dehydration basket, and the labor required for washing can be greatly reduced. . In addition, since the items to be washed are stored in the elongated cylindrical space surrounding the water sprinkling tube in the spin-drying basket, the detergent-containing water spewed out from the watering tube is evenly supplied to the entire laundry. With,
Since the dehydration basket is driven intermittently, the detergent-containing water sufficiently permeates the entire laundry and is shaken off, resulting in a sufficient cleaning action without uneven washing. It can be washed cleanly. In addition, by continuing to supply water from the water source to the water spray bottle even after the detergent is used up in the reservoir, fresh water can sufficiently soak into the entire laundry and be shaken off, so that it can be rinsed immediately after washing. Furthermore, after the rinsing is completed, the laundry basket can be dehydrated by continuously driving the dewatering basket while the water supply from the water source is cut off. Therefore, it is possible to carry out a series of steps from washing to dehydration continuously by simply controlling the water supply and driving the dehydration basket, which is an excellent effect.
