[0023] FIG. 1 is a flowchart schematically illustrating a car wash method using a car wash kiosk having car wash and fuel discount coupon issuance functions according to the present invention. Specific details for implementing the invention

[0024] Hereinafter, an embodiment of a car wash method using a car wash kiosk having car wash and fuel discount coupon issuance functions according to the present invention will be described in detail with reference to the drawings.

[0025] FIG. 1 is a flowchart schematically illustrating a method for washing a vehicle using a car wash kiosk having a car wash and fuel discount coupon issuance function according to the present invention. The present invention is performed by a customer using the car wash service moving the vehicle in front of the car wash device and then operating the car wash kiosk.

[0026] Referring to FIG. 1, the car wash kiosk first guides the customer using the car wash service to select the desired car wash service, either a regular car wash or a gas voucher car wash (step S1).

[0027] In step (S1), the car wash service selection is provided through the user interface of the car wash kiosk, and a general car wash button and a fuel voucher car wash button are intuitively arranged so that the customer using the car wash service can make a selection.

[0028] In addition, brief information or icons regarding the corresponding car wash service can be displayed on the general car wash button and the fuel voucher car wash button, allowing customers using the car wash service to easily distinguish between them.

[0029] Furthermore, a brief explanatory text regarding the differences between a regular car wash and a gas voucher car wash, or the benefits associated with them, can be displayed together.

[0030] In the aforementioned step (S1), if a customer using the car wash service selects a general car wash service, the car wash kiosk guides the customer using the car wash service to select a car wash course (S10).

[0031] In step (S10), the selection of a car wash course is provided through the user interface of the car wash kiosk, and a standard car wash course button, a premium car wash course button, and a top-tier car wash course button are intuitively arranged so that customers using the car wash service can make a selection.

[0032] In addition, the standard car wash course button, premium car wash course button, and top-tier car wash course button can display brief information and costs for the corresponding car wash course, allowing customers using the car wash service to easily distinguish between them.

[0033] For example, the standard car wash course button, premium car wash course button, and top-tier car wash course button can each display the car wash service sequence and wash time.

[0034] As another example, the standard car wash course button, premium car wash course button, and premium car wash course button may display car wash service costs of 10,000 won, 12,000 won, and 14,000 won, respectively.

[0035] In the aforementioned step (S10), when a customer using the car wash service selects a desired car wash course button, the car wash kiosk guides the customer using the car wash service to pay for the car wash service (step S11).

[0036] In step (S11), instructions for paying the car wash service fee are provided through the user interface of the car wash kiosk, and the customer using the car wash service can perform payment for the car wash service fee by following the instructions of the car wash kiosk.

[0037] For example, payment for car wash services can be made through various payment methods such as credit cards, cash, and RF cards, and customers using the car wash service can complete the payment by selecting a payment method according to the instructions presented at the car wash kiosk and entering specific information.

[0038] Here, specific information may be a car wash discount coupon held by a customer using the car wash service, and in step (S11), payment for the final car wash amount with the car wash discount amount applied may be performed upon recognition of the car wash discount coupon.

[0039] As described above, when payment for the car wash service is completed (step S11), the car wash kiosk informs the customer using the car wash service whether the payment has been approved (step S12).

[0040] For example, if payment is successfully completed, the car wash kiosk screen may display an animation or image announcing the start of the car wash, along with a message such as "Payment completed. Car wash will begin soon." Additionally, an alert sound confirming the successful payment may be played.

[0041] Conversely, if payment approval fails, a brief explanation of the cause of the failure (insufficient card balance, card information error, etc.) may be displayed along with an error message such as, "Payment failed. Please check your payment information again or select a different payment method."

[0042] At this time, the car wash kiosk may return to the step (S11) of guiding the car wash service user to pay for the car wash service and attempt to pay again, or the car wash service may be terminated, although not shown.

[0043] When payment is successfully completed in the aforementioned step (S12), the car wash kiosk issues a car wash discount coupon to the customer using the car wash service (step S13).

[0044] In step (S13), the car wash discount coupon can be printed as a paper QR code and issued at a car wash kiosk, or issued as a mobile coupon and sent via SMS or a dedicated app after the user enters their mobile device number.

[0045] The issued car wash discount coupon can be used on your next car wash service by scanning the QR code or entering the discount code.

[0046] In addition, the issued car wash discount coupon may display the discount amount and a validity period restricting use to a certain period from the date of issuance.

[0047] For example, when selecting the standard car wash course button, the premium car wash course button, and the top-tier car wash course button, the car wash discount coupons issued may display discount amounts of 1,000 won, 2,000 won, and 3,000 won, respectively.

[0048] In addition, car wash discount coupons may include a unique discount code or QR code information to prevent reuse, and car wash kiosks may display a notice such as, "A car wash discount coupon has been issued. Please use it on your next visit."

[0049] When a car wash discount coupon is issued at step (S13), the car wash kiosk guides the customer using the car wash service to enter the car wash device (step S14).

[0050] In step (S14), the car wash kiosk can instruct the car wash service customer to enter the car wash device from the front and stop at the guide line through screen and voice guidance.

[0051] In addition, it can provide instructions on precautions for entry, such as folding the side mirrors, and display a message indicating that you must wait briefly after stopping the vehicle until the car wash starts automatically.

[0052] Here, the car wash device may be a brushless automatic car wash device, but the car wash device is not limited to a brushless automatic car wash device.

[0053] Then, when the vehicle enters the car wash device according to the guidance of the car wash kiosk in step (S14), the car wash device provides a car wash for the vehicle according to the control of the car wash kiosk, and when the car wash is completed, the car wash device terminates the car wash service (step S15).

[0054] Meanwhile, in the aforementioned step (S1), if a customer using the car wash service selects the gas voucher car wash service, the car wash kiosk guides the customer using the car wash service to select a car wash course (S20).

[0055] In step (S20), the selection of a car wash course is provided through the user interface of the car wash kiosk, just as in step (10), and a general car wash course button, a premium car wash course button, and a high-end car wash course button are intuitively arranged so that customers using the car wash service can select.

[0056] In addition, the standard car wash course button, premium car wash course button, and top-tier car wash course button can display brief information and costs for the corresponding car wash course, allowing customers using the car wash service to easily distinguish between them.

[0057] For example, the standard car wash course button, premium car wash course button, and top-tier car wash course button can each display the car wash service sequence and wash time.

[0058] As another example, the standard car wash course button, premium car wash course button, and premium car wash course button may display car wash service costs of 10,000 won, 12,000 won, and 14,000 won, respectively.

[0059] In the aforementioned step (S20), when a customer using the car wash service selects a desired car wash course button, the car wash kiosk guides the customer using the car wash service to select a desired discount method between a fixed-amount fuel discount or a discount per liter of fuel (step S21).

[0060] In step (S21), the selection of the discount method is provided through the user interface of the car wash kiosk, and the fixed-amount fuel discount button and the per-liter fuel discount button are intuitively arranged so that customers using the car wash service can select.

[0061] In addition, brief information about the corresponding discount method may be displayed on the fixed-price fuel discount button and the discount per liter fuel button.

[0062] For example, the fixed-amount discount button and the discount button per liter of fuel can display 'discount by a set amount' and 'discount based on fuel volume' respectively to help customers using the car wash service understand.

[0063] In the aforementioned step (S21), if a customer using the car wash service selects a fixed-rate fuel discount method, the car wash kiosk guides the customer using the car wash service to pay for the car wash service (step S21-1).

[0064] In step (S21-1), instructions for paying the car wash service fee are provided through the user interface of the car wash kiosk, and customers using the car wash service can pay the car wash service fee by following the instructions of the car wash kiosk.

[0065] For example, payment for car wash services can be made through various payment methods such as credit cards, cash, and RF cards, and customers using the car wash service can complete the payment by selecting a payment method according to the instructions presented at the car wash kiosk.

[0066] As described above, when payment for the car wash service is completed (step S21-1), the car wash kiosk informs the customer using the car wash service whether the payment has been approved (step S22-1).

[0067] For example, if payment is successfully completed, the car wash kiosk screen may display an animation or image announcing the start of the car wash, along with a message such as "Payment completed. Car wash will begin soon." Additionally, an alert sound confirming the successful payment may be played.

[0068] Conversely, if a payment fails, a brief explanation of the cause of the failure (insufficient card balance, card information error, etc.) may be displayed along with an error message such as, "Payment failed. Please check your payment information again or select a different payment method."

[0069] At this time, the car wash kiosk may return to the step (S21-1) of guiding the customer using the car wash service to pay for the car wash service and attempt to pay again, or the car wash service may be terminated, although not shown.

[0070] When payment is successfully completed in the aforementioned step (S21-2), the car wash kiosk issues a fuel discount coupon to the customer using the car wash service (step S23-1).

[0071] In step (S23-1), the fuel discount coupon can be printed as a paper QR code and issued at a car wash kiosk, or issued as a mobile coupon and sent via SMS or a dedicated app after the user enters their mobile device number.

[0072] The issued car wash discount coupon can be used when using the refueling service by scanning the QR code or entering the discount code.

[0073] In addition, the issued fuel discount vouchers may display a fixed discount amount and a validity period that restricts use to a certain period from the date of issuance.

[0074] For example, when selecting the standard car wash course button, the premium car wash course button, and the top-tier car wash course button, the fuel discount coupons issued may display discount amounts of 2,000 won, 3,000 won, and 4,000 won, respectively.

[0075] In addition, fuel discount coupons may include a unique discount code or QR code information to prevent reuse, and car wash kiosks may display a notice such as, "A fuel discount coupon has been issued. Please use it when refueling."

[0076] When a fuel discount coupon is issued in step (S23-1), the car wash kiosk guides the customer using the car wash service to enter the car wash device (step S24-1).

[0077] In step (S24-1), the car wash kiosk can instruct the customer using the car wash service to enter the car wash device from the front and stop at the guide line through screen and voice guidance.

[0078] In addition, it can provide instructions on precautions for entry, such as folding the side mirrors, and display a message indicating that you must wait briefly after stopping the vehicle until the car wash starts automatically.

[0079] Here, the car wash device may be a brushless automatic car wash device, but the car wash device is not limited to a brushless automatic car wash device.

[0080] Then, when the vehicle enters the car wash device in accordance with the instructions of the car wash kiosk in step (S24-1), the car wash device provides a car wash for the vehicle under the control of the car wash kiosk, and when the car wash is completed, the car wash device terminates the car wash service (step S25-1).

[0081] Meanwhile, in the aforementioned step (S21), if a customer using the car wash service selects a discount method per liter of fuel, the car wash kiosk guides the customer using the car wash service to pay for the car wash service (step S21-2).

[0082] In step (S21-2), instructions for paying the car wash service fee are provided through the user interface of the car wash kiosk, and customers using the car wash service can pay the car wash service fee by following the instructions of the car wash kiosk.

[0083] For example, payment for car wash services can be made through various payment methods such as credit cards, cash, and RF cards, and customers using the car wash service can complete the payment by selecting a payment method according to the instructions presented at the car wash kiosk.

[0084] As described above, when payment for the car wash service is completed (step S21-2), the car wash kiosk informs the customer using the car wash service whether the payment has been approved (step S22-2).

[0085] For example, if payment is successfully completed, the car wash kiosk screen may display an animation or image announcing the start of the car wash, along with a message such as "Payment completed. Car wash will begin soon." Additionally, an alert sound confirming the successful payment may be played.

[0086] Conversely, if a payment fails, a brief explanation of the cause of the failure (insufficient card balance, card information error, etc.) may be displayed along with an error message such as, "Payment failed. Please check your payment information again or select a different payment method."

[0087] At this time, the car wash kiosk may return to the step (S21-2) of guiding the customer using the car wash service to pay for the car wash service and attempt to pay again, or the car wash service may be terminated, although not shown.

[0088] When payment is successfully completed in the aforementioned step (S22-2), the car wash kiosk issues a fuel discount coupon to the customer using the car wash service (step S23-2).

[0089] In step (S23-2), the fuel discount coupon can be printed as a paper QR code and issued at a car wash kiosk, or issued as a mobile coupon and sent via SMS or a dedicated app after the user enters their mobile device number.

[0090] The issued car wash discount coupon can be used when using the refueling service by scanning the QR code or entering the discount code.

[0091] In addition, the issued fuel discount coupon may display a discount amount per liter of fuel and a validity period that restricts use to a certain period from the date of issuance.

[0092] For example, when selecting the standard car wash course button, the premium car wash course button, and the top-tier car wash course button, the fuel discount coupons issued may display discount amounts of 30 won, 60 won, and 90 won per liter, respectively.

[0093] In addition, fuel discount coupons may include a unique discount code or QR code information to prevent reuse, and car wash kiosks may display a notice such as, "A fuel discount coupon has been issued. Please use it when refueling."

[0094] When a fuel discount coupon is issued in step (S23-2), the car wash kiosk guides the customer using the car wash service to enter the car wash device (step S24-2).

[0095] In step (S24-1), the car wash kiosk can instruct the customer using the car wash service to enter the car wash device from the front and stop at the guide line through screen and voice guidance.

[0096] In addition, it can provide instructions on precautions for entry, such as folding the side mirrors, and display a message indicating that you must wait briefly after stopping the vehicle until the car wash starts automatically.

[0097] Here, the car wash device may be a brushless automatic car wash device, but the car wash device is not limited to a brushless automatic car wash device.

[0098] Then, when the vehicle enters the car wash device in accordance with the instructions of the car wash kiosk in step (S24-2), the car wash device performs a car wash on the vehicle under the control of the car wash kiosk, and when the car wash is completed, the car wash device terminates the car wash service (step S25-2).
