The present invention relates to a laundry machine, and more particularly, to a laundry machine that can be used by the public outside the coin box.

In general, a washing machine is a device for washing a washing product by washing, rinsing, dehydrating, drying, etc. so as to remove the contamination on clothes, bedding, etc. (hereinafter, referred to as washing matter). .

The laundry machine is classified into a household washing machine and a commercial washing machine according to the purpose of use, and the household washing machine is provided in each home and used to wash the washings generated by the members of the household. The laundry machine is provided in a separate store and used to rent and receive a predetermined fee to a customer who wants to wash the washings.

As illustrated in FIG. 1, a configuration of a general commercial laundry machine will be described with a washing machine as an example.

A main body 1 forming an outer appearance, a tub provided inside the main body 1 so as to be buffered by a spring and a damper, a drum rotatably disposed inside the tub, and having a plurality of handmade holes formed on an outer circumferential surface thereof; It is configured to include a motor mounted to the rear of the tub to rotate the drum, and the main PC for controlling the function of the washing machine. Here, the main PC is provided with a power control unit 17 that can turn on or off the power to the drive unit. In addition, the commercial washing machine is provided with a fee processing device 10 consisting of a card reader 12 and a coin box 14 to receive cash, such as card payment and coins so that customers can pay the fee.

Such a commercial laundry machine is installed in a public place and used by a customer for the purpose of profit of a business operator. The commercial laundry machine is designed and manufactured to have superior profitability, safety, maintainability, durability, and the like compared to the domestic laundry machine.

That is, the commercial laundry machine requires not only an apparatus for processing a fee and a control algorithm of the apparatus, but also a separate laundry algorithm for maximizing the profit of the operator. In addition, the commercial laundry machine should be manufactured in a structure that prevents the product from being damaged or the parts lost by the customer, and also makes the operation very easy and quick during maintenance. Therefore, it is necessary to prevent the customer from attempting an illegal operation such as disassembling part of the device so that the washing machine can be operated without paying a fee.

2 is a block diagram showing a circuit configuration of a conventional washing apparatus.

The main PCB receives information on an operation state from a driving unit of the washing machine, and controls the power control unit 17 for supplying power to the driving unit to control the operation of the driving unit of the washing machine as the stroke proceeds. The main PCB supplies power required by the coin box 14, and when the user pays a fee, the coin box 14 outputs a control signal indicating that the payment has been made to the main body. Therefore, the washing apparatus may be set to supply power to the driving unit from the power control unit 17 when a control signal is input from the coin box 14. In addition, the main PCB may transmit information on the operating state of the laundry machine to the coin box 14 in relation to the fee processing.

However, in the related art, since the coin box PCB is separated from the commercial power source, only the control signal can be transmitted and received. Therefore, power must always be applied to the main body 1 in order to receive the control signal according to the settlement process from the coin box PCB. There was a problem that unnecessary power consumption occurs.

In addition, in the conventional commercial laundry machine, since only a low voltage direct current flows through the communication cable 15 connecting the coin box 14 and the main PCB of the control panel, the communication cable 15 is removed from the coin box 14. Cutting was not a safety hazard. Therefore, when a signal similar to the control signal output from the coin box 14 is input to the separated communication cable 15 using a portable device, the washing machine can be operated without paying a fee.

However, even if the coin box 14 is to be embedded in the product, there is a limitation in reducing the size because there is a space for storing components and cash for payment processing. . In addition, since the commercial laundry machine is exported to the domestic as well as overseas, it is necessary to install a coin box 14 according to the power situation of each country, it was forced to adopt a separate method of exterior.

The present invention is to solve the above problems, it is an object of the present invention to provide a commercial laundry machine having a structure that can operate the main body according to whether or not the payment at all times without applying power to the main body.

It is still another object of the present invention to provide a commercial laundry machine designed to prevent a customer from arbitrarily operating a power source of the laundry machine.

In order to achieve the above object, the present invention provides a laundry body; Provides a commercial laundry machine comprising a; processing charges and connected to an external power source and a charge processing device having a power control unit for controlling the power is applied to the main body.

Then, the power is applied to the main body through the power control unit according to the payment of the fee.

At this time, the charge processing device starts to accumulate time when the laundry start signal is input from the main body.

In addition, if it is determined that the accumulated time has passed the reference time, the washing operation is stopped and the washing operation is continued when an additional fee is paid.

Here, the power control unit cuts off the power of the main body when the washing end signal is input from the main body.

The power control unit includes a relay, and controls the power of the main body on and off through the relay.

On the other hand, the present invention is a power cable for introducing power to the main body; And an auxiliary power cable connecting the power cable and the tariff processing device and applying power to the main body from the power control unit.

The power cable and the charge processing device are connected to the auxiliary power cable to supply power to the main body through the charge processing device.

In addition, it further comprises a communication cable for transmitting the driving information of the main body to the charge processing device.

Therefore, according to the present invention, since power is applied to the main body after payment processing is performed, unnecessary power consumption can be prevented.
