Description

Technical Field

[0001] The present invention relates to a quick-release joint for the raw material end of a beverage dispenser, and specifically, to a quick-release joint for the raw material end of a beverage dispenser and a cleaning method for a beverage dispenser.

Background Art

[0002] As shown in Patent Document 1, when a general beverage dispenser and a raw material supply device for supplying raw materials for beverages (for example, a flexible packaging bag for storing raw materials or a tank for storing raw materials) are not connected, the connection part between the two is exposed to the air and is thus easily contaminated. Also, if raw materials for beverages remain at the connection part of the beverage dispenser, harmful bacteria are likely to multiply.

[0003] Even if the connection parts of both are cleaned before connection, after connection, the connection parts of both cannot be cleaned from the outside.

[0004] Therefore, in conventional beverage dispensers and raw material supply devices, there is a food safety problem in that the raw materials for beverages are easily contaminated and spoiled by passing through the parts contaminated by bacteria.

The raw material connecting pipe is for connecting to the raw material discharge end of the raw material supply device, and is installed inside the outer tube so as to be able to slide between a cleaning position and a raw material supply position relative to the outer tube. When the raw material connecting pipe is in the cleaning position, the raw material connecting pipe is separated from the beverage supply machine end pipe section, and the space within the branch pipe section is in communication with the space within the beverage supply machine end pipe section, and The present invention provides a quick-release fitting for the raw material end of a beverage supply machine, characterized in that when the raw material connecting pipe is positioned at the raw material supply location, the raw material connecting pipe approaches the beverage supply machine end pipe section, and communication between the space within the branch pipe section and the space within the outer pipe section is blocked by the pipe wall of the raw material connecting pipe.

[0008] Furthermore, the present invention relates to a method for cleaning a beverage dispenser, which involves using a cleaning system to clean the above-mentioned quick-release fitting for the raw material end of the beverage dispenser, the raw material supply device, and the beverage dispenser. The cleaning system includes a detergent dispensing end, The raw material supply device includes a raw material delivery end, The raw material dispensing end of the raw material supply device has a raw material outlet and an opening / closing stopper that is configured to move between a closed position that closes the raw material outlet and an open position that opens the raw material outlet, and The steps include: connecting the raw material connecting pipe of the quick-release fitting to the raw material discharge end of the raw material supply device, connecting the beverage supply machine end pipe portion of the quick-release fitting to the raw material inlet end of the beverage supply machine, connecting the detergent discharge end of the cleaning system to the branch pipe portion of the quick-release fitting, and positioning the raw material connecting pipe at the cleaning position; The steps include supplying detergent from the detergent discharge end of the cleaning system, the detergent entering the branch pipe portion of the quick-release joint, passing through the beverage dispenser end pipe portion and entering the beverage dispenser, The present invention provides a method for cleaning a beverage dispenser, comprising the steps of: stopping the supply of the detergent from the detergent discharge end of the cleaning system; sliding the raw material connecting pipe from the cleaning position toward the raw material supply position to the raw material supply position; and having the pressing portion of the quick-release joint push the opening / closing valve portion from the closed position toward the open position. [Effects of the Invention]

[0009] The present invention provides a quick-release fitting for the raw material end of a beverage dispenser, with a branch pipe section for connecting to a cleaning system. When the raw material connecting pipe is in the cleaning position, the cleaning system can supply detergent into the quick-release fitting for the raw material end of the beverage dispenser, thereby cleaning the raw material outlet end of the raw material supply device and the raw material inlet end of the beverage dispenser.

[0010] Furthermore, when the raw material connecting pipe is positioned for raw material supply, the communication between the space inside the branch pipe section and the space inside the outer pipe section is blocked by the pipe wall of the raw material connecting pipe, thus blocking the passage of detergent. This allows the raw material in the raw material supply device to enter the quick-release fitting for the raw material end of the beverage supply machine, or to enter the beverage supply machine via the quick-release fitting for the raw material end of the beverage supply machine.

[0011] As a result, the connection between the beverage dispenser and the raw material supply device can be easily cleaned by the cleaning system, preventing the growth of harmful bacteria and preventing contamination and spoilage of beverage raw materials, thereby preventing food safety issues.

[0017] Hereinafter, the present invention will be described in detail.

[0018] The first embodiment of the quick release joint 100 for the raw material end of the beverage dispenser of the present invention is shown in FIG. 1.

[0019] The quick-release joint 100 for the raw material end of the beverage dispenser is installed between the raw material outlet end 201 of the raw material supply device 200 and the raw material inlet end 301 of the beverage dispenser 300, so as to connect the raw material outlet end 201 of the raw material supply device 200 and the raw material inlet end 301 of the beverage dispenser 300.

[0020] The raw material supply device 200 is used to contain and supply the raw materials for beverages, and includes, but is not limited to, flexible packaging bags for containing the raw materials or tanks for containing the raw materials.

[0021] The beverage dispenser 300 is a device that dispenses beverages as products, and examples include, but are not limited to, smart cookers and drink dispensers.

[0022] The raw material dispensing end 201 of the raw material supply device 200 has a raw material outlet 201a and an opening / closing plug 201b that is configured to move between a closed position (see Figures 1, 3, and 4) that closes the raw material outlet 201a and an open position (see Figure 5) that opens the raw material outlet 201a.

[0023] For example, by installing an elastic member (not shown) at the raw material dispensing end 201 and biasing the opening / closing valve 201b toward the closed position with the force acting on the elastic member, it is possible to prevent the raw material in the raw material supply device 200 from leaking out of the raw material dispensing end 201.

[0024] The quick-release fitting 100 for the raw material end of the beverage dispenser includes a quick-release fitting 1, as shown in Figure 1.

[0025] The quick-release fitting 1 includes a main body 11 and a raw material connecting pipe 12.

[0026] The main body 11 has a raw material supply device end pipe section 111 and a beverage supply machine end pipe section 112 which is connected to the raw material supply device end pipe section 111 and also connects to the raw material input end 301 of the beverage supply machine 300.

[0027] In this embodiment, as shown in Figure 1, the raw material supply device end pipe section 111 and the beverage supply machine end pipe section 112 are located on opposite sides.

[0028] The raw material end pipe section 111 has an outer pipe section 111a, a branch pipe section 111b extending from the outer pipe section 111a and connected to a washing system 400 that can supply detergent, and a pressing section 111c installed inside the outer pipe section 111a and pressed against the opening / closing stopper section 201b.

[0029] In this embodiment, as shown in Figure 1, the branch pipe section 111b extends downward from the outer pipe section 111a in the drawing, meaning that the space inside the branch pipe section 111b and the space inside the outer pipe section 111a are in communication.

[0030] The raw material connecting pipe 12 is for connecting to the raw material discharge end 201 of the raw material supply device 200, and is installed inside the outer pipe section 111a so that it can slide between a cleaning position (see Figures 1, 3, and 4) and a raw material supply position (see Figure 5) relative to the outer pipe section 111a.

[0031] Specifically, in this embodiment, as shown in Figure 1, the outer tube portion 111a is fitted over the raw material connecting tube 12, and the raw material connecting tube 12 has a plurality of sealing rings 121 that are installed between the outer tube portion 111a and the raw material connecting tube 12 so as to seal the gap between the inner surface of the outer tube portion 111a and the outer surface of the raw material connecting tube 12.

[0032] When the raw material connecting pipe 12 is in the cleaning position, as shown in Figures 3 and 4, the raw material connecting pipe 12 is separated from the beverage supply machine end pipe section 112, and the space inside the branch pipe section 111b communicates with the space inside the beverage supply machine end pipe section 112, and the opening / closing valve section 201b is in the closed position. When the raw material connecting pipe 12 is in the raw material supply position, as shown in Figure 5, the raw material connecting pipe 12 approaches the beverage supply machine end pipe section 112, and the communication between the space inside the branch pipe section 111b and the space inside the outer pipe section 111a is blocked by the pipe wall of the raw material connecting pipe 12, and the pressing portion 111c pushes the opening / closing valve section 201b from the closed position to the open position.

[0033] Regarding the position of the raw material connecting pipe 12, when it is in the cleaning position, the raw material connecting pipe 12 is further away from the beverage supply machine end pipe section 112 compared to when it is in the raw material supply position, and when it is in the raw material supply position, the raw material connecting pipe 12 is closer to the beverage supply machine end pipe section 112 compared to when it is in the cleaning position.

[0034] Referring to Figures 1 and 2, the first embodiment of a cleaning method for a beverage dispenser 300 that applies the first embodiment of the quick-release fitting 1 for the raw material end of the beverage dispenser will be described below.

[0035] In the first embodiment of the cleaning method for the beverage dispenser 300 of the present invention, the cleaning is performed by the cleaning system 400 on the quick-release joint 1 for the raw material end of the beverage dispenser, the raw material supply device 200, and the beverage dispenser 300 of the first embodiment.

[0036] The cleaning system 400 includes a detergent dispensing end 401 for supplying detergent.

[0037] Furthermore, the first embodiment of the method for cleaning the beverage dispenser 300 includes the following steps.

[0038] Referring to Figures 2 and 3, step S11 is the step of connecting the raw material connecting pipe 12 of the quick-release fitting 1 to the raw material discharge end 201 of the raw material supply device 200, connecting the beverage supply end pipe 112 of the quick-release fitting 1 to the raw material inlet end 301 of the beverage supply device 300, connecting the detergent discharge end 401 of the cleaning system 400 to the branch pipe 111b of the quick-release fitting 1, and positioning the raw material connecting pipe 12 in the cleaning position.

[0039] Referring to Figures 2 and 4, step S12 is the step of supplying detergent from the detergent discharge end 401 of the cleaning system 400, so that the detergent enters the branch pipe section 111b of the quick-release joint 1, passes through the beverage dispenser end pipe section 112, and enters the beverage dispenser 300.

[0040] The aforementioned detergent is, for example, a food-grade detergent.

[0041] In this embodiment, the detergent is a food-grade detergent.

[0042] In step S12, the detergent passes through the raw material discharge end 201 of the raw material supply device 200, the raw material inlet end 301 of the beverage supply machine 300, and the inside of the quick-release fitting 1, cleaning the raw material discharge end 201 of the raw material supply device 200, the raw material inlet end 301 of the beverage supply machine 300, and the inside of the quick-release fitting 1.

[0043] The detergent then flows out of the beverage outlet (not shown) of the beverage dispenser 300 through the internal conduit through which the beverage flows, thereby cleaning the internal conduit of the beverage dispenser 300.

[0044] Referring to Figures 2 and 5, step S13 is the step of stopping the supply of the detergent by the detergent discharge end 401 of the cleaning system 400, and sliding the raw material connecting pipe 12 from the cleaning position toward the raw material supply position so that the pressing portion 111c of the quick-release joint 1 pushes the opening / closing plug portion 201b from the closed position toward the open position.

[0045] After step S13, the raw material supply device 200 can supply the raw material to the beverage supply device 300 via the quick-release fitting 1.

[0046] Then, after using the beverage dispenser 300 for a predetermined period, the process is repeated periodically (for example, once every four hours) by returning to the step S11 "position the raw material connecting pipe 12 in the cleaning position," and then performing steps S12 and S13 in order. This cleans the raw material discharge end 201 of the raw material supply device 200, the raw material inlet end 301 and internal piping of the beverage dispenser 300, and the inside of the quick-release fitting 1, thereby regularly maintaining cleanliness of the raw material discharge end 201 of the raw material supply device 200, the raw material inlet end 301 and internal piping of the beverage dispenser 300, and the inside of the quick-release fitting 1.

[0047] Additionally, after each wash with detergent (food-grade detergent), an extra step can be taken to rinse with clean water to completely remove the detergent.

[0048] A second embodiment of the quick-release fitting 100 for the raw material end of a beverage dispenser of the present invention is similar to the first embodiment of the quick-release fitting 100 for the raw material end of a beverage dispenser, except that it further includes a three-way valve 2, as shown in Figure 6.

[0049] The three-way valve 2 has a main pipe 21 and a branch pipe 22 extending from the main pipe 21.

[0050] The main pipe 21 has a first pipe section 211 located on one side of the branch pipe 22 and a second pipe section 212 located on the other side of the branch pipe 22.

[0051] In this embodiment, as shown in Figure 6, the branch pipe 22 of the three-way valve 2 extends from the main pipe 21 to the lower side of Figure 6, the first pipe section 211 of the main pipe 21 is located on the left side of the branch pipe 22, and the second pipe section 212 is located on the right side of the branch pipe 22, that is, the first pipe section 211 and the second pipe section 212 are located on opposite sides of the branch pipe 22.

[0052] The first pipe section 211 is connected to the beverage dispenser end pipe section 112 of the quick-release fitting 1.

[0053] The second pipe section 212 is for connecting to the raw material feeding end 301 of the beverage supply machine 300.

[0054] The branch pipe 22 is for connecting to the cleaning system 400.

[0055] Referring to Figures 6 and 7, a second embodiment of a cleaning method for a beverage dispenser that applies the quick-release fitting 1 for the raw material end of the beverage dispenser according to the second embodiment will be described below.

[0056] A second embodiment of the beverage dispenser cleaning method of the present invention is performed by the cleaning system 400 on the beverage dispenser raw material end quick-release joint 1, raw material supply device 200, and beverage dispenser 300 of the second embodiment.

[0057] The cleaning system 400 includes a detergent dispensing end 401 for supplying detergent and a detergent recovery end 402 for recovering the detergent.

[0058] Furthermore, a second embodiment of the method for cleaning the beverage dispenser 300 includes the following steps.

[0059] Referring to Figures 7 and 8, step S21 is the step of connecting the raw material connecting pipe 12 of the quick-release fitting 1 to the raw material discharge end 201 of the raw material supply device 200, connecting the second pipe section 212 of the three-way valve 2 to the raw material inlet end 301 of the beverage supply machine 300, connecting the detergent discharge end 401 of the washing system 400 to the branch pipe 22 of the three-way valve 2, connecting the detergent recovery end 402 to the branch pipe section 111b of the quick-release fitting 1, and positioning the raw material connecting pipe 12 in the washing position.

[0060] Referring to Figures 7 and 9, step S22 is the step of supplying detergent from the detergent discharge end 401 of the cleaning system 400, so that the detergent enters the branch pipe 22 of the three-way valve 2, passes through the branch pipe section 111b of the quick-release joint 1, and enters the detergent recovery end 402 of the cleaning system 400.

[0061] In step S22, the detergent passes through the inside of the branch pipe 22 and the first pipe section 211 of the three-way valve 2, the inside of the quick-release fitting 1, and the raw material discharge end 201 of the raw material supply device 200, cleaning the inside of the branch pipe 22 and the first pipe section 211 of the three-way valve 2, the inside of the quick-release fitting 1, and the raw material discharge end 201 of the raw material supply device 200.

[0062] Referring to Figures 7 and 10, step S23 is the step in which the raw material connecting pipe 12 is slid from the cleaning position toward the raw material supply position so that the pressing portion 111c of the quick-release fitting 1 pushes the opening / closing plug portion 201b from the closed position toward the open position.

[0063] Step S24 is the step in which detergent is supplied from the detergent discharge end 401 of the washing system 400, and the detergent enters the branch pipe 22 of the three-way valve 2, passes through the second pipe section 212, and enters the beverage dispenser 300.

[0064] In step S24, the raw material supply device 200 can supply raw materials to the first pipe section 211 of the three-way valve 2 via the quick-release fitting 1, and the detergent passes through the inside of the branch pipe 22 and the second pipe section 212 of the three-way valve 2 and the raw material inlet end 301 of the beverage dispenser 300, cleaning the inside of the branch pipe 22 and the second pipe section 212 of the three-way valve 2 and the raw material inlet end 301 of the beverage dispenser 300.

[0065] Furthermore, the detergent cleans the internal piping of the beverage dispenser 300 by flowing out of the beverage outlet (not shown) of the beverage dispenser 300 through the internal piping through which the beverage flows inside the beverage dispenser 300.

[0066] Referring to Figures 7 and 11, step S25 is the step of stopping the supply of detergent by the detergent dispensing end 401 of the cleaning system 400.

[0067] After step S25, the raw material supply device 200 can supply the raw material to the beverage supply device 300 via the quick-release fitting 1 and the three-way valve 2.

[0068] Then, after using the beverage dispenser 300 for a certain period, by periodically (for example, once every four hours) repeating steps S24 and S25, the inside of the branch pipe 22 and the second pipe section 212 of the three-way valve 2, and the raw material inlet 301 and internal piping of the beverage dispenser 300 can be cleaned, thereby maintaining cleanliness of the inside of the branch pipe 22 and the second pipe section 212 of the three-way valve 2, and the raw material inlet 301 and internal piping of the beverage dispenser 300.

[0069] Furthermore, after using the beverage dispenser 300 for a certain period, the process can be repeated periodically (for example, once every few days) by returning to step S21, "positioning the raw material connecting pipe 12 in the cleaning position," and then performing steps S22, S23, and S25 in order. This cleans the inside of the branch pipe 22 and the first pipe section 211 of the three-way valve 2, the inside of the quick-release fitting 1, and the raw material discharge end 201 of the raw material dispenser 200, thereby maintaining cleanliness of these areas.

[0070] Additionally, after each wash with detergent (food-grade detergent), an extra step can be taken to rinse with clean water to completely remove the detergent.

[0071] According to the above, when the raw material connecting pipe 12 is in the cleaning position, the branch pipe section 111b of the quick-release fitting 100 for the beverage supply machine raw material end connects to the cleaning system 400, allowing the cleaning system 400 to supply detergent into the quick-release fitting 100 for the beverage supply machine raw material end to clean the raw material discharge end 201 of the raw material supply device 200 and the raw material inlet end 301 of the beverage supply machine 300.

[0072] Furthermore, when the raw material connecting pipe 12 is positioned at the raw material supply location, the communication between the space inside the branch pipe section 111b and the space inside the outer pipe section 111a is blocked by the pipe wall of the raw material connecting pipe 12. This blocks the passage of detergent, allowing the raw materials in the raw material supply device 200 to enter the quick-release fitting 100 for the raw material end of the beverage supply machine, or further to enter the beverage supply machine 300 via the quick-release fitting 100 for the raw material end of the beverage supply machine. As a result, the connection between the beverage supply machine and the raw material supply device can be easily cleaned by the cleaning system, preventing the growth of harmful bacteria and preventing contamination and spoilage of the beverage raw materials, thereby preventing food safety issues.

[0073] Therefore, the objectives of the present invention can be reliably achieved.

[0074] The above embodiments are illustrative in illustrating the principles and effects of the present invention and do not limit it. A person skilled in the art can make some modifications and alterations to the above embodiments, provided that they do not deviate from the spirit and scope of the invention. Therefore, all modifications and alterations made by a person skilled in the art, provided that they do not deviate from the spirit of the invention, should also be considered to fall within the scope of protection of the present invention.
