Description

Laundry system {SYSTEM FOR WASHING MACHINE}

The present invention relates to a washing machine, in particular, the cause of the product itself, problems in installation, problems in the local characteristics, changes in lifestyle patterns of the user, and appropriately responds to the increase in ease of use, improvement in washing performance, and improvement in operation efficiency. It's about a washing machine that makes it happen.

In general, a washing machine is a device that removes contaminants from contaminated laundry through washing, rinsing, and dehydration according to a predetermined algorithm, and is fully automatic using horizontal rotation of a rotary blade, outer tank, or inner tank (washing tank / dehydrating tank). A washing machine or a drum washing machine using vertical rotation of the drum can be broadly classified.

Such a washing machine has been developed for a variety of washing courses, functions, etc. in order to respond to a variety of needs of the user and applied to the actual product.

As shown in FIG. 1, the washing machine according to the related art includes a motor 10 for directly or indirectly rotating a washing blade, an inner tank, or an outer tank, other loads 11 such as a water supply valve, a drain valve, and the like. A key input unit 12 for inputting an operation instruction related to washing, a display unit 13 for displaying an operation state or a function of a washing machine, and a washing operation corresponding to an operation command of a user input through the key input unit 12 It comprises a system microprocessor 14 for controlling the drive of the motor 10, the load 11 to achieve this and for controlling the display unit 13 to display the operation state or function.

At this time, the display unit 13 is provided with a light-emitting diode (LED) and a ROM (ROM) for storing a non-changeable laundry related program in the system microprocessor 14.

Referring to the operation of the washing machine according to the prior art configured as described above are as follows.

First, the user 'turns on' the power of the washing machine, puts laundry into the washing tank, and then inputs a washing instruction through the key input unit 12.

Subsequently, the system microprocessor 14 recognizes the washing instruction, reads the washing program from the internal ROM, and drives the motor 10 and various loads 11 based on the washing program.

Then, the display unit 13 is controlled to display the current laundry progress state and the like.

Unlike conventional home appliances, such a conventional washing machine may not function properly due to incompatibility of a built-in program and various usage environments, even if a product itself is not broken, or a user may mistake a product and request a repair. In many cases, the serviceman repairing the product could not identify the cause of the product's failure.

First, let's look at the incongruity of the built-in program and the usage environment.

There is no problem in the product itself, but the user may not be satisfied with the washing performance, which is often the cause of the problem of water hardness. In other words, washing performance is greatly affected by water hardness (hard water / sweet water) difference.In order to improve washing performance, it is necessary to change the control program such as the rotation angle of washing blade and washing time to match the program and environment. A conventional washing machine cannot change a preset program.

In addition, the nature of the laundry changes according to the change of the family members of the user, for example, the newly married couple's laundry can perform standard washing, but when you have children, laundry such as diapers occurs, hygiene is very important Therefore, a program with enhanced rinsing performance should be applied, but the conventional washing machine cannot change the program.

As such, the conventional washing machine cannot change the program, and thus, the problem caused by the change of the living pattern cannot be solved.

Next, if the service environment is not a fault of the product itself is mistaken as a failure, but the serviceman does not find the cause, or because of this improper repair,

In the dehydration stroke, the washing tank does not rotate or rotates at low speed, so dehydration may not proceed. This may be caused by an abnormality in the motor itself, but due to the excessive tension of the detergent caused by the excessive tension of the washing tank. The rotation of the motor is constrained and the motor may be damaged by the overload. In this case, however, the serviceman cannot grasp the cause of the failure, and it is difficult to prepare a countermeasure.

In addition, if the water supply time for washing is prolonged due to problems such as water pressure, installation location (high / low land), and water supply method of the washing machine installed, the user may recognize that there is a problem with the water supply and notify the manufacturer of the malfunction. do. In this case, the serviceman checks the water supply valve. If the water supply valve does not have any problem, the serviceman cannot determine the cause of the failure.

In the above case, if the serviceman can know the usage history, failure history, etc. of the washing machine in detail, the service person can infer and interpret the use environment that is recognized as a failure or failure of the product and parts, and can take optimal measures. Since it is impossible to grasp the product's operation status, usage history, failure history, etc., it is unable to identify the above-mentioned causes and therefore cannot cope properly.

The washing machine according to the prior art has the following problems.

First, since the operation state of the product, the history of use, failure history, etc. can not be stored, when replacing the parts without identifying the above-mentioned causes when repairing the product, that is, the hardware does not prevent the same problem from occurring.

Second, since the washing program that is not changeable is applied to the low-capacity memory, problems such as installation, regional characteristics, and changes in living patterns, which are not abnormalities of the product itself, cannot be solved.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to replace the pre-stored program with an appropriate program according to the use environment of the washing machine, the change of household members, the change of the flower pattern, the change of seasons, etc. Or to provide a laundry system that can be changed.

It is another object of the present invention to provide a laundry system that grasps the use history of a washing machine, the usage history of each accessory device of the washing machine, etc., to identify the root cause of the failure, and to completely solve the failure.

Still another object of the present invention is to provide a laundry system, which enables a user to obtain washing information for developing an improved washing machine by grasping a washing pattern, washing contents, and a cause of failure of a user.
