Description

structurally detachable fuel dispenser

[0001] Various embodiments of the present invention relate to a structurally separated fuel dispenser, and more specifically, to a structurally separated fuel dispenser in which an electronic payment unit, a fuel dispensing unit, and a flow rate unit are isolated and separated at a certain distance from each other, thereby resolving the disadvantages of a conventional fuel dispenser in which the electronic payment unit, the fuel dispensing unit, and the flow rate unit are integrated into a single unit, such as large volume and integration.

[0002] A fuel dispenser refers to equipment or device used at a fueling station to transfer a required amount of fuel from a fuel storage tank and directly dispense it into the fuel tank of a vehicle or the like.

[0003] A fuel dispenser largely comprises an electronic payment unit responsible for electronic payments, a fueling unit including fueling nozzles and hoses to perform fueling functions, and a flow unit including motors and pumps to transfer fuel from a fuel storage tank to the fueling unit.

[0004] However, conventional fuel dispenser structures typically featured an integrated design where the electronic payment unit, fuel dispensing unit, and flow rate unit were mostly contained within a single main body case.

[0005] For this reason, conventional integrated fuel dispensers had the problem of requiring a significantly large volume. Consequently, the following problems occurred.

[0006] First, there were disadvantages such as the potential for a higher rate of safety accidents due to obstructing the view of customers refueling, and significant limitations on the usable site area of ​​gas stations because the fuel dispenser itself occupies a large volume.

[0007] Second, since the flow section was located inside the main body of the fuel dispenser installed on the ground at the gas station, there was a disadvantage of significant noise and vibration occurring during use. This resulted in inconvenience during use and a decrease in user satisfaction.

[0008] Third, conventional integrated fuel dispensers had the disadvantage that if structural or part changes were required for at least one of the electronic payment, fuel dispensing, or flow rate sections, a type approval modification procedure was necessary for the entire unit due to its integrated structure. Furthermore, if a problem or malfunction occurred in a part, repair, maintenance, or replacement work was required for the entire unit, resulting in a disadvantage of long maintenance times. In particular, considering the frequent failures of the electronic payment section, conventional integrated fuel dispensers are at a disadvantage in terms of maintenance.

[0009] As prior art related to the present invention, there is JP7375783B2 (hereinafter referred to as the prior art), which discloses technology regarding a refueling device. However, in the case of the prior art disclosed therein, the structure in which the components of the flow section, including a refueling pump and a flow meter for refueling the refueling section, are located inside the main body case retains the disadvantages of conventional integrated refueling devices.

[0010] The objective of the present invention is to provide a structurally separated fuel dispenser that can resolve the disadvantages associated with the large volume and integration of the existing fuel dispenser in which the electronic payment unit, fuel dispensing unit, and flow rate unit are integrated, by isolating and separating the electronic payment unit, fuel dispensing unit, and flow rate unit from each other.

[0011] In addition, the objective of the present invention is to provide a structurally separated fuel dispenser that minimizes volume by positioning the electronic payment unit on a pillar or wall or separating it into a self-supporting structure, positioning the fuel dispensing unit in a small fuel dispenser body erected on the ground at a location isolated from the electronic payment unit, and burying the flow unit underground or in a pit to reduce user inconvenience caused by vibration and noise.

[0012] The objects of the present invention are not limited to those mentioned above, and other unmentioned objects and advantages of the present invention may be understood from the following description and will be more clearly understood by the embodiments of the present invention. Furthermore, it will be readily apparent that the objects and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims.

[0013] To achieve the above objective, according to one aspect of the present invention, a structurally separated fuel dispenser can be provided that resolves the disadvantages caused by the large volume of conventional integrated fuel dispensers by isolating and separating the electronic payment unit, the fuel dispensing unit, and the flow rate unit. For example, the electronic payment unit may be positioned on a pillar or wall or separated into a self-supporting structure, the fuel dispensing unit may be positioned on a fuel dispensing body erected on the ground at a location isolated from the electronic payment unit to minimize volume, and the flow rate unit may be buried underground or in a pit to reduce user inconvenience caused by vibration and noise.

[0014] A structurally separated fuel dispenser according to one embodiment comprises: an electronic payment unit responsible for electronic control and payment in relation to a fuel dispensing operation; a fuel dispensing unit that injects fuel into a fuel supply target; and a flow unit that transfers fuel from a fuel storage tank and supplies fuel to the fuel dispensing unit, wherein the electronic payment unit, the fuel dispensing unit, and the flow unit are separated and arranged at different locations, separated from each other by a certain distance.

[0015] According to one embodiment, the fuel dispensing unit comprises: a small fuel dispensing main body installed on the ground within a gas station and separated from the electronic payment unit at a certain distance from each other; a fuel supply hose provided on the small fuel dispensing main body for transporting fuel supplied from the flow rate unit; a fuel supply nozzle connected to the fuel supply hose for injecting the fuel transported through the fuel supply hose into a fuel supply target; and a fuel supply nozzle holder provided on the small fuel dispensing main body for storing the fuel supply nozzle.

[0016] According to one embodiment, the electronic payment unit includes a recessed electronic payment unit that is separated from the fueling unit by a certain distance and is embedded in a pillar or wall within the gas station.

[0017] According to one embodiment, the electronic payment unit includes a self-standing electronic payment unit that is independently positioned on the ground separately from the fuel dispenser, and the self-standing electronic payment unit further includes a main body for a self-standing electronic payment unit that is individually installed at a certain distance from the small fuel dispenser main body within the gas station and to which the self-standing electronic payment unit, which is in the form of a pad, can be connected in a detachable manner.

[0018] According to one embodiment, the electronic payment unit includes an ODT (Outdoor Terminal) unit that provides a refueling-related user interface; a display unit that visually displays refueling-related information; a control unit that controls refueling-related operations according to user commands; and a payment unit that provides refueling-related payment functions.

[0019] According to one embodiment, the flow portion may be an underground-buried type flow portion that is separated from the oiling portion and buried underground.

[0020] According to a preferred embodiment, the underground-buried flow unit comprises: an underground-buried housing that is separated from the fuel supply unit and buried underground; an underground-buried motor pump unit provided inside the underground-buried housing and connected to the fuel storage tank by a fuel pipe, and pumping fuel from the fuel storage tank to supply fuel to the fuel supply nozzle; an underground-buried solenoid valve provided inside the underground-buried housing and controlling the flow rate of the fuel supplied to the fuel supply nozzle by the underground-buried motor and pump unit; and an underground-buried flow meter pulse generator provided inside the underground-buried housing and detecting the flow rate when fuel is supplied to the fuel supply nozzle.

[0021] According to one embodiment, the flow unit may be a pit-buried type flow unit that is separated from the oiling unit and accommodated inside a pit located underground.

[0022] According to one embodiment, the pit-embedded flow unit comprises: a pit-embedded motor pump unit provided inside the pit and connected to the oil storage tank by an oil pipe, which pumps oil from the oil storage tank and supplies oil to the fueling nozzle; a pit-embedded solenoid valve provided inside the pit and which controls the flow rate of the oil supplied to the fueling nozzle by the pit-embedded motor and pump unit; and a pit-embedded flow meter pulse generator provided inside the pit and which detects the flow rate when oil is supplied to the fueling nozzle.

[0023] According to one embodiment, the pit is formed below the ground where the small fuel dispenser body is installed, and is a structure that is open at the top and concave downward, and the pit includes a cover that covers the open top. Preferably, the pit may include a vapor detection sensor provided inside the pit. The vapor detection sensor detects vapor components diffused around the fuel pipe, enabling real-time detection of fuel leakage. In addition, it can detect in real-time even when vapor generated at the gas station accumulates inside the pit due to the characteristic that it is heavier than air, thereby enabling rapid ventilation.

[0024] According to one embodiment, the flow unit may be a ground-supporting flow unit installed on the ground, separated from the fuel supply unit.

[0025] According to one embodiment, the ground-mounted self-supporting flow unit comprises: a ground-mounted self-supporting housing installed on the ground and separated from the fuel supply unit; a ground-mounted self-supporting motor pump unit provided inside the ground-mounted self-supporting housing and connected to the fuel storage tank by a fuel pipe, and pressurizing fuel from the fuel storage tank to supply fuel to the fuel supply nozzle; a ground-mounted self-supporting solenoid valve provided inside the ground-mounted self-supporting housing and controlling the flow rate of fuel supplied to the fuel supply nozzle by the ground-mounted self-supporting motor and pump unit; and a ground-mounted self-supporting flow meter pulse generator provided inside the ground-mounted self-supporting housing and detecting the flow rate when fuel is supplied to the fuel supply nozzle.

[0026] Specific details of other embodiments are included in the specific details and drawings for carrying out the invention.

[0027] According to various embodiments, there is one or more of the following effects.

[0028] First, by isolating and arranging the electronic payment, fuel dispensing, and flow rate sections—which have distinct functions and roles within the fuel dispenser—at a certain distance from one another, there is an advantage in that it can simultaneously resolve various disadvantages caused by the large volume of existing integrated fuel dispensers.

[0029] Second, since the flow unit can be separated from the electronic payment unit and the fuel dispensing unit and buried underground or in a pit (i.e., a box-shaped concrete structure with an open top), user inconvenience caused by vibration and noise from the flow unit during fuel dispensing operations can be reduced. As a result, there is an advantage in improving user satisfaction.

[0030] Third, since the fuel dispensing unit is separated from the fuel volume unit and the electronic payment unit and installed on the ground with a minimized volume, the problem of obstructing customer visibility caused by the large volume of existing integrated fuel dispensers can be resolved, and the rate of safety accidents resulting from this can be reduced. In addition, since the fuel dispensing unit (i.e., the main body of the fuel dispenser) itself does not take up a large volume, there is an advantage of reducing restrictions on the usable land area of ​​the gas station.

[0031] Fourth, since the electronic payment unit is separated from the fueling unit and is embedded in a canopy column or wall or installed as a freestanding unit, there is an advantage in that maintenance and replacement work on the electronic payment unit, which frequently malfunctions, is easier.

[0032] Fifth, as the electronic payment, fuel dispensing, and flow rate sections are all separated, it has the advantage of resolving issues such as the type approval change procedures that were previously required for the entire integrated fuel dispenser.

[0033] In addition to the effects described above, the specific effects of the present invention are described together with the specific details for implementing the invention below.

[0044] A fuel dispenser refers to equipment or device used at a fueling station to transfer a required amount of fuel from a fuel storage tank and directly dispense it into a fuel tank (i.e., a fuel supply target), such as a vehicle.

[0045] A fuel dispenser largely comprises an electronic payment unit responsible for electronic payments, a fueling unit including fueling nozzles and hoses to perform fueling functions, and a flow unit including motors and pumps to transfer fuel from a fuel storage tank to the fueling unit.

[0046] Figure 1 is a conceptual diagram briefly illustrating a conventional integrated fuel dispenser.

[0047] Referring to FIG. 1, the conventional fuel dispenser (40) included an electronic payment unit (42) responsible for electronic payment, etc., a fueling unit (43) including a fuel nozzle, a fuel hose, etc., and a flow unit (44) including a motor and a pump, etc., in a single main body (41) of large volume.

[0076] The small fuel dispenser body (201) can be installed on the ground above the gas station, separated from the electronic payment unit (100) at a certain distance from each other, and can also be spatially separated from the underground-buried flow unit (310) above and below ground. Accordingly, user inconvenience caused by vibration and noise that may occur during the operation of the motor pump, etc., can be eliminated.

[0077] Referring to FIG. 7, it shows a case where the flow section (300) is a pit-buried flow section (320).

Accordingly, the presence of vapor components diffused around the oil pipe (22) and the pit-embedded flow section (310) can be detected in real time to detect whether oil is leaking. Furthermore, since the vapor generated at the gas station is heavier than air, it allows for real-time detection and rapid ventilation even when the vapor accumulates inside the pit (20).

[0085] According to one embodiment, the electronic payment unit (100) may include an ODT (Outdoor Terminal) unit (101) that provides a fuel-related user interface and a display unit (102) that visually displays fuel-related information.

[0086] Additionally, according to one embodiment, the electronic payment unit (100) may include a control unit (103) that controls refueling-related operations according to user commands and a payment unit (104) that provides refueling-related payment functions.

Accordingly, user inconvenience caused by vibration and noise that may occur during the operation of the motor pump, etc., can be eliminated.

[0089] Referring to FIG. 8, it shows a case where the flow unit (300) is a ground-supported flow unit (330).

[0090] The ground-mounted self-supporting flow unit (330) can be installed on the ground separated from the fueling unit (200) at a certain distance from each other.

[0096] As described above, according to various embodiments, the electronic payment unit, fuel dispensing unit, and flow rate unit, which have distinct functions and roles within the fuel dispenser, can be isolated and arranged at a certain distance from each other. Accordingly, various disadvantages caused by the large volume of conventional integrated fuel dispensers can be resolved at once.

[0097] In addition, according to various embodiments, the flow unit can be separated from the electronic payment unit and the fuel dispensing unit and buried underground or in a pit, thereby reducing user inconvenience caused by vibration and noise from the flow unit during fuel dispensing operations. As a result, user satisfaction can be improved.

[0098] In addition, according to various embodiments, the fuel dispensing unit is separated from the flow rate unit and the electronic payment unit and installed on the ground with a minimized volume, thereby resolving the problem of obstructing customer visibility caused by the large volume of conventional integrated fuel dispensers. Accordingly, the rate of safety accidents that may occur due to difficulty in securing visibility can be reduced. Furthermore, since the fuel dispensing unit (i.e., the fuel dispensing body) itself does not occupy a large volume, restrictions on the usable land area of ​​the gas station can be reduced.

[0099] In addition, according to various embodiments, the electronic payment unit is separated from the fueling unit and is embedded in a canopy column or wall or installed as a freestanding unit, making maintenance and replacement work for the electronic payment unit, which is prone to frequent breakdowns, advantageous.

[0100] In addition, according to various embodiments, the electronic payment unit, fuel dispensing unit, and flow rate unit are all separated, thereby resolving the issues regarding type approval change procedures that were previously required for the entire integrated fuel dispenser.
