Abstract

The present invention discloses a power failure compensation method for a laundry room machine that includes a payment device for collecting a payment for operating a laundry room machine, and an interface for communicating with a communicator. The method includes: a) detecting power failure by determining whether or not a pulse generated from an AC (alternative current) power is interrupted for a predetermined time; b) storing compensation data having information about a state of a laundry room machine when power failure occurs; and c) operating the laundry room machine according to the stored compensation data when the power is supplied again.

Claims

1. A power failure compensation method for compensating a power failure of a laundry room machine that includes a payment device for collecting a payment for operating a laundry room machine, and an interface for communicating with a communicator, is used for performing at least one of a washing operation and a drying operation, receives payment insertion information from the payment device, receives a selection of courses allowable by the inserted payment, and performs a predetermined operation according to the selected course, comprising the steps of:

a) detecting power failure by determining whether or not a pulse generated from an AC (alternative current) power is interrupted for a predetermined time;

b) storing compensation data having information about a state of a laundry room machine when power failure occurs; and

c) operating the laundry room machine according to the stored compensation data when the power is supplied again.

2. The power failure compensation method of claim 1, wherein the compensation data includes at least one of an inserted payment, a selected course, a remaining time of the selected course.

3. The power failure compensation method of claim 1, wherein the predetermined time of the step a) is about 20 msec.

4. A commercial laundry room machine comprising:

an interface for communicating payment collecting information with a payment device disposed corresponding to each laundry room machine;

a control panel for controlling operation of a laundry room machine according to communicating information of the interface, storing compensation data including information about a state of a laundry room machine when electric power is interrupted, and operating the laundry room machine according to the compensated data.

5. The commercial laundry room machine of claim 4, wherein the compensation data includes at least one of inserted payment, a selected course, and a remaining time of a selected course.

6. The commercial laundry room machine of claim 5, wherein the laundry room machine further includes a display unit for displaying operating state and/or compensation data.

7. The commercial laundry room machine of claim 4, wherein the laundry room machine is a washer or a dryer.
