Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to setting the optimum washing rotation speed and dewatering rotation speed for clothes to be washed, in a washing machine such as a dry cleaner or a water washer-extractor. Washing machine rotation speed 1al
a method and apparatus.

[Conventional technology]

For example, in a conventional dry cleaner that cleans clothes using an organic solvent such as perchlorethylene, as shown in FIG.
When the #i is closed and operation is started, the steps #i are generally carried out in the following order.

(1) Pump up the solvent 4 from the solvent tank 3 via the valve 5 with the pump 6 and transfer it to the processing tank 10 through the path consisting of the valve 7 and filter 8 or the path consisting of the valve 9.
Send in the required amount.

(2) Slowly rotate the processing drum 1 with the cleaning motor 5 and apply the solvent 4 to the processing tank 10. The clothes 2 are washed by circulating through the button trap 12, the valve 13, the pump 6, and a circuit consisting of a valve 7 and a filter 8, or a circuit consisting of a valve 9.

(3) Processing tank 10, button trap 12, valve 13,
The liquid is drained through the path of the pump 6, valve 14, and distiller 15, and then the processing drum 11 is rotated at high speed by the liquid removing motor 52 to centrifugally separate the solvent 4 in the clothing 2 and let it flow. This completes the first step of prewashing.

(4) Next is the second step, the main hospital, where the above ill,
Repeat step +21.

(5) Processing tank 10, button trap 12, valve 13,
The liquid is drained into the solvent tank 3 through the path of the valve 5, and then the processing drum 11 is rotated at high speed by the liquid removing motor 52 to remove the liquid from the clothing 2.
The solvent 4 inside is centrifuged and drained. This concludes the main session.

(6) Next is the third step of drying, in which the processing drum 11 is again slowly moved by the cleaning motor 5 in the direction of the arrow 2o between the recovery air duct 19 consisting of the lift fan 16, the air cooler 17, and the air heater 18 and the processing tank 10. The air is circulated and the clothes 2 are dried. The solvent that evaporates from the clothes 2 enters the water separator 22 via the recovery route 21 in the air cooler 17 (11), and enters the clean tank 24 via the solvent pipe 23.

(7) After drying is completed, the final step is deodorization, in which the dampers 25 and 26 open as shown by the broken lines, fresh air is taken in from the damper 25, and the uncondensed solvent gas that cannot be recovered by the air cooler 17 is exhausted from the damper 26 by the exhaust 11. To deodorize the solvent odor in clothing 2.

The above is an example of the dry cleaner's process from cleaning to drying and deodorization.

Next, a conventional method of driving the processing drum 11 will be described with reference to FIG. No. 5 is a cleaning motor that drives the processing drum No. 1 at low speed during cleaning, drying, and deodorization. An induction motor is used, and it can rotate forward and reverse in a certain pattern. Reference numeral 52 denotes a deliquid motor that drives the processing drum 1 at high speed during deliquification to centrifugally deliqe, and uses a double-shaft induction motor. This is an electromagnetic clutch that disconnects the cleaning motor 5 from the KQ cleaning motor 51 to prevent the cleaning motor 5 from free-running rotation at high speed when the cleaning motor 52 is driven.

The button has a deceleration function so that it rotates at a predetermined speed during cleaning, drying, deodorizing, and deliquing.

[Problem that the invention seeks to solve]

In the drive system of the conventional dry cleaner mentioned above, the rotation speed of the processing drum 1 is automatically determined, and in the conventional dry cleaner, the rotation speed of the processing drum 1 is determined slightly depending on the target diameter of the processing drum 1.・The speed was fixed at 33 rpm+n during deodorization and 400 rpm during dehydration. Furthermore, the rotational speed of the processing drum II during washing is determined to be such that the clothing 2 lifted up by the rotation of the processing drum 1 falls from a high position and efficiently produces a knocking effect. However, at this speed, various announcements have been made recently, especially in the apparel industry. As for the delicate clothes that are being washed, there have been many accidents where the clothes have been damaged due to the washing effect, and it can no longer be said that the IIQ J internal rotation training during washing has become a problem. The rate of liquid removal from clothing changes depending on the centrifugal force generated by the rotation speed, but if the rotation speed is fixed, as mentioned above, there is a risk of clothing accidents for delicate clothing, and energy savings (due to high-performance liquid) for durable clothing.
There is a special case in which it is not possible to achieve a large effect on the drying process in the subsequent process due to the liquid removal rate (1~, which also shortens the processing time).

The present invention was developed as follows: As clothing becomes more diverse, there is an increase in the number of clothing that cannot be washed with conventional washing/machines with a fixed rotation speed. In addition, in view of the fact that even in this type of washing machine there is a demand for energy consumption and short washing time, the above-mentioned conventional problems have been solved. 〃Set I+J chest washing rotation speed and removal/r& rotation speed according to R clothing VC 11! It is an object of the present invention to provide a method and apparatus for washing and cleaning which are capable of saving energy and cleaning in a short period of time.

[Means for Solving the Problems] The method of controlling the rotation speed of a washing machine according to the present invention uses a motor with variable speed control as the motor for washing and removing liquid, and adjusts the washing rotation speed to the clothes to be washed. and the number of rotations for removing liquid are varied within predetermined ranges, respectively, to perform optimal washing and removing liquid operations for the clothes.

Furthermore, the rotation speed control device of the washing machine according to the present invention includes a 1LIT variable speed control motor for washing and deliquoring, a variable speed motor control device for controlling this motor, and pre-stored information corresponding to the clothes to be washed. It is characterized by comprising a command voltage storage circuit that transmits a command voltage to the oTf speed motor control sub-device and sets the optimum washing rotation speed and deliquing rotation speed corresponding to the clothes. be.

[Effect]

According to the present invention, in order to simplify and reduce the cost of the drive system, the two-motor system of the cleaning motor and the dehydrating motor is replaced with a one-motor system using a variable speed motor using an inverter, etc.
This makes it possible to change the rci1 dispersion in a wide range from washing, drying, deodorizing to deliquing to renci (
1. By varying the rotation speed during washing, by adjusting the mechanical force due to the washing effect on delicate clothing, the optimal washing operation is performed to suit the clothing, and the rotation speed during deafening and dehydration is variable. By doing so, it performs a weak dehydration operation for delicate clothes and a strong dehydration operation for durable clothes, and performs an optimal deliquification operation suitable for the clothing, and a strong deliquification operation for the filter. By doing so, it is possible to shorten the drying time in the post-process and to save labor, thereby solving the problems of the conventional method.

[Effects of the Invention] As described above, the present invention provides the following excellent effects.

(1) By changing the rotation method and rotation speed of the processing drum during washing, the falling distance of the clothes can be reduced compared to the conventional method of dropping clothes from 111 hours on the clock to produce a washing effect. In addition, in combination with rocking that does not rotate the processing drum too much, it becomes possible to wash delicate clothing without damaging it.

(2) When removing liquid from delicate clothing, lowering the rotation speed of the processing drum will reduce the effect of centrifugal force with the processing drum, and prevent holes from leaving marks on the clothing. Wrinkles caused by centrifugal dehydration force become less noticeable.

Furthermore, for durable clothing, by increasing the number of rotations of the processing drum and applying high-temperature liquid, less energy is required for drying in the post-process, and time is shortened.
