Description

[Detailed description of the invention] The original F! Part A particularly relates to a centrifugal dehydrating washing machine that automatically performs washing, cleaning, and dehydration.

Conventionally, this type of washing machine includes a whirlpool type, a stirring type, and a drum type washing machine, but the stirring type has a complicated mechanical drive system for the stirring blades, requires a large electric motor, and has low cleaning power. It had the disadvantage of being weak. The drum type has the following advantages, such as less damage to the cloth and less need for toilet water, but it has weak cleaning power, and most detergents on the market have a cleaning mechanism that uses a rotary drum that is closed. However, there are drawbacks such as the fact that the sand cleaning power is further reduced due to foaming. On that point, the 14-volume type is widely used in the domestic market. Although this is a well-known method, there are dissatisfaction with the fact that it causes a lot of damage to the fabric and causes a lot of tangles in the fabric.

Therefore, an object of the present invention is to propose a new washer mt that improves the drawbacks of the whirlpool type. For more information,
Pulsator as a stirring rotary blade used in a spiral system
The aim is to improve the drawbacks of the spiral type by reviewing the shape and operating method.

That is, the substantially circular bottom 11'rijO1 in the spiral type
-4 The area ratio of the pulsator placed at the bottom to the cleaning shell is α5~! The TIA range is set to , and the forward and reverse operation cycles of the nonoru sweater are set to 5 seconds or less in the forward direction, 0.5 seconds or less in the pause period, and 5 seconds or less in the reverse direction, and the pulsator rotation speed r at that time.
1100 to 280 rPm, even if the bath ratio indicated by the ratio of the water tray to the container is reduced, there is little waste, there is less tangle of cloth, and the washing machine still has cleaning power. can be provided.

In order to provide a detailed explanation of the present invention, as shown in FIG. 1, a spring 4. Lifting machine with hanging rod 5 *6
The entire outer tank 2 is supported by a suspension 9'F for vibration isolation.

On the mounting plate 3, there is a water valve 8 that communicates with the drainage lower provided in the outer tank 2, and this drainage valve 8 and the outer frame 11F! : A connecting drain hose 9 and a bearing clutch device 15 are attached.

The motor 16 is supported by the mounting plate 3 using the motor mounting plate 14 . The power is transmitted via the motor 16 and the belt 17 to the Basquera 11 or the pulsator 13. The bearing clutch device 15 includes a shaft (not shown) that drives a pulsator 13 as a rotary blade, and a ninth shaft that rotates at high speed the basket 11 that serves as a washing and dehydrating tank during dehydration (usually the pulsator drive described above). The shaft is provided in a hollow shape around the outer periphery of the shaft. Basquera) 11
It has a dehydration hole 12. Attached to the top of the basket 11 is a balance ring 18 filled with a suitable liquid. A tank cover 19 is attached to the upper part of the outer tank 2. At the top of the outer frame 1, there is a slot for taking in and taking out items to be washed.
There is a top cover 20 with a 7tk function, a panel 21, and a timer 22 inside that controls the entire operation.
etc. are stored.

The operation is to put the items to be washed into the basket 11,
Water is injected using a water supply valve (not shown). When the specified water level is reached,
The water level is detected and the motor 16t is rotated 19 times according to the instructions of the timer 22.

As shown in FIG. 2, in the conventional centrifugal dehydration washing machine, the outer diameter d of the pulsator 13' is made smaller than the inner diameter of the Basquera 11. Therefore, the eyelids that are washed between the water levels H are twisted by the rotation of the pulsator 13. Stool causes a lot of damage to the fabric, and it also gets tangled up a lot.

In particular, the bath ratio is 107. If the value is less than /j4, the object to be cleaned will not rotate smoothly and the motor power will increase.

Therefore, in this embodiment, as shown in FIG. 3, the ratio dt/D'e of the outer diameter d of the pulsator 13" to the inner diameter of the basket 11 is set at 0.5 to 1. Taking the relationship between the value and the pulsator rotation speed in Fig. 4, we get
The current product level is pulsator rotation speed asorpm
If the value is 1 when the pulsator outer diameter is set to about 200 and the basket diameter is set to 390, then for example, if the pulsator outer diameter d*'je is set to about 300, the pulsator rotation speed will be When the distance is 2801m or less, the value -+ is tZ8Kf'! I can experimentally confirm that simply increasing i:136h can also reduce the current product level.

The cleaning performance at this time was 280 rpm as shown in Figure 5.
In the case of m, it was confirmed that the improvement was as much as 40%. However, if the diameter of the pulsator blades is increased, as shown in Figure 6, the amount of cloth entangled due to twisting and entanglement between the items to be washed will increase, and the damage to the cloth will increase proportionally, and the motor input will also become extremely large. This is confirmed! ! Ta.

On the other hand, if you frequently turn the pulsator forward and backward, you will get tangled in the cloth! My friend thought that it might be possible to prevent this. Therefore, the pulsator's reversal period (t) is currently automatic, in which it rotates forward for 20 seconds, pauses for 3 seconds, and then reverses for another 20 seconds, but we considered what would happen if we varied this t. , the results are shown in FIG. That is, in order to achieve the current product level, for example, the pulsator rotation speed zsor
It was confirmed that during PM hours, the operating time for forward and reverse rotations should be 5 seconds, and the rest period should be 1 second.

However, in a short period of time such as 0.5 seconds of operation and 0.5 seconds of rest, it was confirmed that the cleaning ratio decreased by 1't- as shown in FIG. Therefore, it was found that it is better to set the reversal period to t-0, 5 seconds to 5 seconds, and to set the operation (of course, forward, reverse > t-O, S to about 1 second. However, the rest time is the so-called unearned For example, if the washing time is t-10 minutes, then 0.5 to 5 seconds is the working time, α5 to 1 second is the unworked time, and the total of these is the washing time.In this way, it is reversed. time period.

If you choose the outer diameter of the pulsator and the inner diameter of the basket, for example, if you have a Haharu sweater with a diameter of around 200 mm, a pulsator rotation speed of around 38 orpm, and a basket with a diameter of around 390 mm, the reversal time will be 20 seconds 0N, 13 seconds OFF cycle, 2.5 to 2.
8~36ha degree or washing capacity t-
Wash even if multiplied by 1 or 2 times.

In order to improve cloth damage and cloth tangling, the outer diameter of the pulsator was changed to φ3.
00m, reversal period 'i 0.5 to 5 seconds ON.

0, 5 to 1 seconds OFF' and pulsator rotation speed t-28
This can be achieved by reducing the value to below Orpm.

The input at this time is 350W 8 degrees, food, laundry f/k
It was found that the value remained constant despite the increase in t-. Therefore, if we look at the experiments in this example all together, fabric damage can be reduced by lowering the rotational speed of the pulsator.

The mechanical force applied to the items to be washed from the bottom to the top is determined by setting the outer diameter of the pulsator to 0.5 to 1 relative to the outer diameter of the basket.
It is omnipresent. Considering the carefully selected reversal cycle from the viewpoint of subtraction, by setting it ON for 0.5 to 5 seconds and OFF for 0.5 to 1 second, the cleaning time for 1 wash time is 10 minutes, which is equivalent to or longer than the current genuine product from Mouse. , the performance of sub-damage and cloth entanglement is 4
