Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an improvement in a fully automatic washing machine in which washing, rinsing and spin-drying are performed automatically.

[Prior art]

A fully automatic washing machine automatically performs washing, washing, rinsing, and spin-drying processes according to a preset time cycle. In the washing operation, the rotary blades at the bottom of the washing machine are driven by a motor to rotate at low speed through a speed reduction mechanism to create a water stream, which agitates the laundry and applies mechanical force to the fabric to remove dirt. It is designed to be acted upon. The detergency is achieved by the separation of dirt due to the above-mentioned mechanical force and the chemical action of the detergent, and the detergency of only one is insufficient. With a fully automatic washing machine, after putting in the laundry and detergent without any water in it, you close the lid and press the start switch. Once set, the washing machine will automatically start washing. The feature is that the work can be continued.

Conventional rotor blades operate at high speed (400fIn) and for long periods of time (23
After rotating in one direction (seconds), it paused for a certain period of time (3 seconds), then reversed and created a stream of water that rotated for the same period of time. In this one-way system, 1. Since a vortex is created, the laundry is drawn into the vortex by the water flow, so the detergent dissolves quickly in the early stages of washing, and the washing machine is submerged in water, allowing washing to be done in a short time.

On the other hand, as a new cleaning method, the rotor blades are rotated in one direction for a short period of time (0.8 seconds) at low speed (190 rotations), and then for a certain period of time (0.8 seconds).
, 5 seconds) If the machine pauses, then reverses and rotates for the same amount of time, no vortex will be formed and the washing method will be similar to shaking or massaging. In this case, the detergent does not dissolve quickly, and it takes time for the washing machine to rise to the surface of the water and submerge it, reducing the washing time.
Umu's new short-cycle reversal washing method, which had the problem of not being able to be used effectively to remove dirt, has the advantage of not causing laundry to tangle with each other, making the fabric less squeaky and causing less uneven washing. As mentioned above, this was a problem that required a solution. If the dissolution of the detergent is delayed, there will be no cleaning power due to the printing action, so efficient cleaning cannot be achieved using mechanical action alone. In addition, since the cleaning action is not effective during the time when the face is not above the water surface, efficient cleaning is impossible in this case as well.

In addition, if a mechanical timer is used, the cleaning time limit and the overall time cycle are set by providing irregularities on a 360-degree rotating cam plate and setting the time length cycle. In this case, since the washing time is set and operated by adjusting the knob, when washing;
The rotation time and rest time of the rotor blade in ( ) are selected to be constant and standard values, and it is impossible to clean at the optimal time depending on the purpose. It operated in reverse until after M.

[Purpose of the invention]

The present invention was made in view of the above situation, and an object of the present invention is to provide an all-white M washer that can improve washing efficiency and shorten washing time.

[Summary of the invention]

The full-output washing machine of the present invention has a water tank that is driven by a motor, has rotary blades and a basket built in, is suspended from an outer frame, and is supplied and drained, and washes, rinses, and spins water at a predetermined time cycle. A timer for controlling the rotary blades during normal operation, stoppage, and
A time-nicle that repeats reverse rotation, stop, and forward rotation sequentially,
The first half has a long period and the second half has a short period! The result is -C.

[Embodiments of the invention]

The I71 Iso of the present invention will be explained below using the example of Kuzukusu with reference to Fig. 11 and Fig. 2. Fig. 1 is a front view of No. 11 is a steam circuit diagram.

In Fig. 1, C, 1 is an outer frame, 2 is a top cover that covers the upper surface of the outer frame 1, and 3 is a corner grate, which has a 1 ml capacity at the upper four corners of the outer frame 1, and the water receiving tank 4 is suspended from four corners. I fully support it. A vibration-proof spring 6 is attached to the hanging rod 5 and is formed so as to absorb the vibration of the water receiving tank 4 during dewatering. 7 is a basket that rotates at high speed during spin-drying to centrifugally spin-dry the laundry. Reference numeral 8 denotes a motor, and the power of the motor 8 is transmitted via a belt 9 and a pulley 10 to a clutch deceleration unit 11 and decelerated, and the rotary blade 12
is designed to be driven at low speed. 14 is a water injection hose, 15 is a water injection port for supplying water from a faucet into the water tank 4, 16 (see Fig. 2) is a playback timer, a motor 8,
It is designed to instruct the operation and operation of electrical parts such as the water supply valve 13. Further, the motor 8 rotates in both forward and reverse directions, so that the rotary blade 12 can be repeatedly rotated in the forward and reverse directions.

In FIG. 2, 17 is a capacitor for advancing the phase of the motor 8;
18 is a drain valve, 19 is a power outlet, 20 is a power switch, 21 is a neon lamp, and 22 is a connector.

23 is a pressure switch, 24 is a safety switch, 25 is an instruction 1. Yama U1 Department, micro computers, etc.
11. This is a functional LSR element. 26 is a progress indicator composed of light emitting diodes, and 27 is a power supply circuit section that converts alternating current (AC) into direct current (DC) and generates high voltage (ACl).
This is the part that generates the power supply for the slave timer 16 by converting the low pressure (I) CIOV) to the low pressure (I) CIOV).

Reference numeral 28 denotes an oscillation circuit section which supplies a clock to the instruction control section 25 and also supplies an excavation frequency to the buzzer 29. 30 is an input signal reasoning circuit, which receives inputs 1. The signal is transmitted to the signal path line 31 to the signal control section 25, and 32 is an input switch section. There is. 33 is an output signal path line, and the instruction control unit 25
The signal is transmitted to the progress display section 26 and the drive circuit 34. In addition, the line 35 is connected to the water supply valve 13 via the connector 22, and the line 36 is connected to the forward rotation side of the motor 8.
The line 37 is connected to the reverse rotation side, and the line 38 is connected to the drain valve 18.

In the above configuration, when there is an operation instruction input to the input switch section 32, the signal from the pressure switch 23 is determined, and when the water is not full, the signal is sent from the output circuit of the instruction control section 25 to the drive circuit 34 via the output signal path line 33. The water is amplified and switched, a signal is issued through the line 35 to turn on the water supply valve 13, and water is supplied through the water injection port 15 via the water injection hose 14. Then, when the water is full, pressure switch 2
When the signal No. 3 is switched, the water supply valve 13 is de-energized and the washing process begins.

Washing is usually done by short-cycle reversal, with clockwise rotation on for 0.8 seconds, pause for 0.5 seconds, counterclockwise rotation for 0.8 seconds, and pause for 0.5 seconds. Mechanical force acts on it. In the above-mentioned washing method, the washing time can be up to about 12 minutes, but the washing time can be adjusted to be shorter depending on the degree of dirt. Since the present invention relates to washing in the washing process, the following explanation will be limited to washing.

FIG. 3 is a flowchart showing the operation of the shark routine of the washing process. When a washing process is entered, the washing time is set. Next, check whether the pressure switch 23 is ON,
When NO, the water supply valve 13 is turned ON. When the water accumulates and becomes full, the pressure switch 23 is turned ON, so it is judged as YES, the water supply valve 13 is turned OFF, the process moves to the reversal subroutine, and the washing subroutine is removed and the original process returns. It is something.

FIG. 4 shows the masterpiece of the inversion subroutine at t70-. First, in order to update the washing time, the mask of the subtraction timer is released and subtraction counting is started. The subtracted number is the wash time set at the beginning of FIG. Next, T indicates the washing execution time as T = (washing time) - (subtraction timer value), but until this value reaches the constant To, the rotor operating time tM is set as a constant t1, Pause time tS
is set to a constant t2. When T≧TO, t
M is a constant 13, and TS is changed to a constant t4.

Here, tl>tB, tB>14. tl>tB.

Operation is performed based on the relationship 13>t4. tl is usually 2 to 3 times t3, and tB is also the same (a value of 2 to 3 times t4 is appropriate. tB is 0.8 seconds, and t4 is 0.5 seconds, which are the optimal values for the cloth entanglement characteristics described later. Therefore, tl is about 2 seconds and tB
is approximately 145 seconds. The next process is a flow in which the rotor blade 12 is operated in short-period inversion according to the set tM and tS. The above shows control in which the reversal cycle changes from long to short until the washing execution time reaches To and after that.

The process indicated by the broken line frame 39 in FIG. 4 is for leaving the inversion period at 1/2 to 1/3 at the "Tot" boundary, but the process indicated by the broken line frame 40 in FIG. 5 is for other embodiments of the present invention. In Fig. 5, after processing 'l' 2 'l'o, tl and tB become gradually shorter, and finally 13.t4.
tM and tB are changed until they match. t
1' and tB, and tB and t4 are divided into n equal parts, and the value of 1/n is Δtl.

When Δt2 is assumed, tM=tl−flXΔt1 ts=t2−nXΔt2. According to the process shown in FIG. 5, t1→t3°t2→t
The inversion period variation to 4 can be switched over. n is normally set to switch within one minute. If we look at the above change in terms of the number of inversion cycles, it changes excessively from about 7 inversion cycles to 23 inversion cycles per minute. By making such gradual changes, it is possible to smoothly change the movement of the washing material, and the purpose can be accomplished more effectively. In other words, if the reversal cycle is changed rapidly, the laundry will become lump-like.
It becomes difficult to remove and wash.

FIG. 6 shows ON of the motor 8, 01+'Fiif number, and the relationship between tl and t2 in FIG. 4 (A).

As shown in (0), (in is the forward rotation number 1d and is connected to line 36 to shimotor 8, (b) is the reverse rotation signal that is connected to line 37 and is connected to Tanabata 8. .Furthermore, the relation i system between t3 and t4 is shown in ?9), in which forward and reverse signals are transmitted to the motor 8 in exactly the same way.

FIG. 7 is an explanatory diagram showing the washing time on the horizontal axis and the operating time of the rotating part and the weight time on the vertical axis.

t2. t3. To illustrate the relationship of t4, East Melon 1; IJ in Figure 5 is shown. T after starting washing.

This shows that after a long-period reversal for a fixed period of time until 1 minute, the signal gradually becomes shorter after about 1 minute, and then a short-period reversal for a fixed period of time.

Figure 8 is an explanatory diagram of the effect shown with washing time on the horizontal axis and detergent concentration on the vertical axis. When the detergent is operated in cycles, the detergent is not dissolved smoothly, and the dissolution curve gradually rises as shown by the two-dot chain line A. Actual aB is unloaded without adding any washing material, and tM
=ta.

The curve shows the case of operation at a cycle of t5 = t4, and shows a steep rise pattern in which the concentration increases within a short period of time. The time required to reach the same detergent concentration α% is indicated by the two-dot chain line A.
and solid line B, T'' and T', and two-dot chain line A curve shows T from the start of the set washing time.
Until //, there was no hope of cleaning power due to chemical action,
Cleaning will be performed only by mechanical power. Next, t
M=tl.

When operating at a cycle of tS = t2, the water flow becomes stronger even when the laundry is loaded as shown by the dashed-dotted line C, so the detergent dissolves and reaches the concentration α in the time To, so that the chemical action of the detergent is quickly removed. A cleaning effect can be expected.

Figure 9 is an explanatory diagram of the cloth entanglement rate, and in case 1, tM=t
l, ts = cloth entanglement rate when running for a long period of t2 is 8
%, and in case H, the cloth entanglement rate when operating in a short period of tM=t3°ts=t4 is b%. Since the relationships a) and b hold true, it is undesirable to continue the water flow in case 1 with a long cycle for a long time, and it is meaningful to return the water flow to case 2 as soon as the detergent is dissolved.

In this way, the fully automatic washing machine of the above embodiment rotates forward, stops, reverses, and stops during the washing process.

By making the time cycle of forward rotation and sequential repetition a long cycle in the first half and a short cycle in the second half, it is possible to promote the dissolution of detergent, secure effective washing time during the washing time, and improve washing efficiency. Therefore, the washing time can be shortened, and it is also possible to form a strong water flow that can draw even water-repellent fabrics that do not sink under the water surface, eliminating the need for partial washing and washing evenly and thoroughly. . In addition, by gradually switching from a long cycle to a short cycle, the switch can be made without adversely affecting the cloth tangle.

In addition, by adopting the Naruko timer, even if the washing time is selected and set, it will always operate in a long cycle from the start of washing until the time of To, so the best condition can be achieved without bothering the user. It has chemical action and mechanical power that can remove dirt.

〔Effect of the invention〕

As described above, Honchomei's fully automatic washing machine I has the effect of improving washing efficiency, shortening washing time, eliminating partial washing shortages, and washing clothes evenly and thoroughly.
