[0010] The present invention will be described below through embodiments of the invention, but these embodiments are not intended to limit the scope of the invention covered by the utility model registration claims. Furthermore, not all combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0011] First, an embodiment of the capsule extraction machine (hereinafter referred to as extraction machine 10) equipped with a cleaning function and a human error prevention function according to the present invention will be described in detail with reference to Figures 1 to 5.

[0012] An embodiment of the present invention provides a capsule dispensing machine equipped with a cleaning function and a human error prevention function. This machine draws water from an external water source, heats and pressurizes it, and then extracts it into capsules 100 to produce drinks corresponding to the contents of the capsules 100, such as coffee or tea. The dispensing machine 10 also needs to be cleaned, but if cleaning is not completed, the processor 71 prohibits the continuous production of drinks by the dispensing machine 10, forcing cleaning to be performed. This ensures the quality of the drinks produced and extends the lifespan of the dispensing machine 10. Furthermore, the human error prevention mechanism for cleaning allows the machine to meet the hygiene requirements of some shop users.

[0013] As shown in Figures 1 to 5, the extractor 10 mainly comprises a capsule extractor body 1, a water tank 2, a puncture needle 6, a processor 71, a plurality of function keys 81, a power key 82, and at least one display 83. The capsule extractor body 1 comprises a housing 11, a water supply pipe 12 installed inside the housing 11, a water supply pipe 13, a pump 14, and a heater 17. The water supply pipe 12 is used to introduce water from an external water source, the pump 14 is connected to the water supply pipe 12 and the water supply pipe 13 respectively, and the water supply pipe 13 is connected to the heater 17. The housing 11 also has a capsule storage tank 15 at its top, which is used to store the corresponding capsules 100 when the user needs to produce a drink using the extractor 10. The housing 11 has a beverage nozzle 18 and a tray 19 on its front side, the beverage nozzle 18 is connected to a capsule storage tank 15, and the tray 19 is used to place a cup (not shown), and a fixing base 111 extends from the rear side of the housing 11.

[0014] As shown in FIGS. 1 to 4, the water tank 2 is detachably attached above the fixed base 111 of the housing 11 and is communicated with the water supply pipe 13. The pump 14 is used to extract water from an external water source through the water supply pipe 12 and transport the water from the external water source into the water tank 2 through the water supply pipe 13.

[0015] Specifically, the extractor 10 further includes a control valve set 3, and the control valve set 3 includes a first control valve 31 and a second control valve 32. The first control valve 31 is attached to the bottom end of the water tank 2 and is a mechanical valve. When the pressure inside the water tank 2 is higher than the external pressure, the valve of the first control valve 31 is closed. When the external pressure of the water tank 2 is higher than the internal pressure, the valve of the first control valve 31 is opened. The second control valve 32 is attached to the upper part of the fixed base 111 of the housing 11. When the water tank 2 is attached to the fixed base 111 of the housing 11, the second control valve 32 can be connected to the first control valve 31 at the bottom end of the water tank 2.

[0016] The end of the water supply pipe 12 is communicated with the pump 14. The water supply pipe 13 includes a first water supply pipe 131, a second water supply pipe 132, and a third water supply pipe 133. One end of the first water supply pipe 131 is communicated with the pump 14, and the other end is communicated with the second control valve 32. One end of the second water supply pipe 132 is communicated with the second control valve 32, and the other end is communicated with the heater 17. One end of the third water supply pipe 133 is communicated with the heater 17, and the other end is communicated with the puncture needle 6 and a part of it is housed in the hollow cover body 41 of the upper cover 4. In one embodiment, the second control valve 32 is used to first control the fluid to flow from the first water supply pipe 131 towards the first control valve 31, and then control the fluid to flow from the first control valve 31 towards the second water supply pipe 132. That is, the first control valve 31 and the second control valve 32 are used to control the water from the external water source to first flow into the water tank 2 from the first water supply pipe 131 and then flow into the second water supply pipe 132 from the water tank 2.

[0017] As shown in FIGS. 1 to 4, the extractor 10 according to the present invention further includes an upper lid 4. The upper lid 4 is pivotally attached above the capsule extractor main body 1 and covers the capsule storage tank 15. The upper lid 4 is a hollow lid body 41. The bottom surface of the hollow lid body 41 has a bottom plate 411, and a recessed groove 42 is provided at the front end. The puncture needle 6 is attached to the bottom plate 411 and is disposed at a position corresponding to the capsule storage tank 15. When the user uses the extractor 10 to produce a drink, the capsule 100 is accommodated in the capsule storage tank 15, and the upper lid 4 covers the capsule extractor main body 1 correspondingly. First, the puncture needle 6 punctures the capsule 100 stored in the capsule storage tank 15. The pump 14 and the heater 17 transport high-pressure hot water to the puncture needle 6 through the water supply pipe 13. The puncture needle 6 continuously injects high-pressure hot water into the capsule 100, and the high-pressure hot water is uniformly mixed with the powder in the capsule 100 to form a drink. Finally, the drink is completed and flows out from the beverage nozzle 18.

[0018] The extractor 10 according to the present invention further includes a locking mechanism 5. The locking mechanism 5 includes a movable plate 51 pivotally attached to the upper lid 4. A recessed groove 42 is provided on one side of the upper lid 4. The movable plate 51 is pivotally attached to the inner wall of the recessed groove 42 and may be fitted or protruded into the recessed groove 42. The movable plate 51 further has a movable portion 511. When the movable portion 511 receives a force and the movable plate 51 is rotated in a direction approaching the upper lid 4 until it is fitted into the recessed groove 42, the movable plate 51 is held by the locking mechanism 5 so that the upper lid 4 is locked to the housing 11. When the movable plate 51 is rotated in a direction away from the upper lid 4 until it protrudes into the recessed groove 42, the movable plate 51 releases the holding of the upper lid 4 by the locking mechanism 5 and can be opened with respect to the housing 11, and the capsule storage tank 15 is exposed. By using the locking mechanism 5, the upper lid 4 is prevented from being accidentally opened, and in the process of the capsule 100 being punctured by the puncture needle 6 and hot water being injected, the upper lid 4 is accidentally opened, and situations such as the failure of capsule 100 extraction are prevented.

[0019] In one embodiment, the extraction machine 10 according to the present invention has the characteristic that the water tank 2 is detachably attached to the housing 11, so that the user can manually remove the water tank 2 to replenish the water and manually attach the full water tank 2 to the housing 11, thereby achieving the effect of allowing the user to manually replenish the water in the event of a water outage or the like. Furthermore, when the water tank 2 is attached to the fixing base 111 of the housing 11, the pump 14 first extracts water from an external water source via the water supply pipe 12, and then transports the water from the external water source into the water tank 2 via the water supply pipe 13, thereby achieving an automatic water replenishment function and eliminating the drawback that the user has to manually remove the water tank 2 and replenish the water after brewing multiple drinks.

[0020] In the example shown in Figure 5, in one embodiment, the extractor 10 is further equipped with a processor 71, a power supply 72, a timer 73, a sensor 74, multiple function keys 81, a power key 82, and at least one display 83. The processor 71, power supply 72, timer 73, sensor 74, multiple function keys 81, power key 82, and at least one display 83 are all mounted on a main board (not shown) inside the housing 11, and the processor 71 is electrically connected to the power supply 72, timer 73, sensor 74, multiple function keys 81, power key 82, and at least one display 83 via the main board.

[0021] The processor 71 is installed within the housing 11 and is used to control the pump 14 and heater 17 of the extractor 10 to transport high-pressure hot water and extract it into the capsules 100 in the capsule storage tank 15. In one embodiment, the processor 71 may be implemented as a central processing unit (CPU), a microcontroller (MCU), a programmable logic controller (PLC), a system on a chip (SoC), or an FPGA (Field Programmable Gate Array), etc.

[0022] The power supply 72 is electrically connected to the processor 71, exposed outside the extractor 10 from one side of the housing 11, and is used to connect to the commercial power supply. In one embodiment, the power supply 72 may be a power cord or a transformer.

[0023] The power key 82 is located on the side of the housing 11 and is positioned to trigger the activation of the extraction machine 10. For example, after the extraction machine 10 is connected to commercial power by the power supply 72, the user can activate the extraction machine 10 by pressing the power key 82.

[0024] Multiple function keys 81 are located on the side of the housing 11 and are arranged to trigger the processor 71 so that the pump 14 and water supply piping 13 of the extractor 10 control the transport of water from the water tank 2 to the heater 17, the heater 17 heats the water and transports the high-pressure hot water to the puncture needle 6, and so on, to control the extraction of the capsules 100 in the capsule storage tank 15. In one embodiment, the multiple function keys 81 correspond to different types of drinks, for example, the multiple function keys 81 correspond to different water volumes and temperatures. When a user places different types of capsules 100 in the capsule storage tank 15 and presses the corresponding function key 81, the extractor 10 can extract the capsules 100 with the corresponding water volume and temperature and dispense the manufactured drink from the beverage nozzle 18.

[0025] As shown in Figures 1 to 4, the multiple function keys 81 and power key 82 are installed on the same side of the housing 11. In one embodiment, the power key 82 is installed on the underside of the multiple function keys 81. In one embodiment, the number of power keys 82 is one, and the number of multiple function keys 81 is four. However, the above is merely one specific embodiment of the present invention, and the number and arrangement of keys in the extraction machine 10 according to the present invention are not limited to those shown in Figures 1 and 4.

[0026] In one embodiment, the multiple function keys 81 and power key 82 may be mechanical keys or touch-controlled keys.

[0027] At least one display 83 is mounted on the side of the housing 11 and is configured to emit warning signals. For example, if one of the usage time, number of uses, or output volume of the extractor 10 reaches a predetermined cleaning condition, the processor 71 of the extractor 10 controls the display 83 to flash to notify the user to clean the extractor 10. In one embodiment, the processor 71 controls the display 83 to emit different types of warnings by flashing with different colors, different frequencies, and different durations. Examples include, but are not limited to, cleaning warnings, malfunction warnings, low water level warnings, and warnings that the top lid 4 is not properly closed.

[0028] The display 83 may be a light-emitting diode (LED). In one embodiment, the display 83 is independently mounted on the housing 11 and is exposed to the outside of the surface of the housing 11.

[0029] In one embodiment, the number of displays 83 is the same as the total number of power keys 82 and function keys 81, and these displays 83 are installed within the power keys 82 and function keys 81, respectively. For example, if the extractor 10 has one power key 82 and four function keys 81, it has five displays 83, and these five displays 83 are installed within the power keys 82 and function keys 81, respectively. In this embodiment, since the power keys 82 and function keys 81 are manufactured from transparent or translucent substrates, when a display 83 emits light, the light rays can pass through the power keys 82 and function keys 81, making it visible to the user.

[0030] In one embodiment, the number of displays 83 is the same as the total number of power keys 82 and function keys 81, and these displays 83 are installed so as to surround the outer edges of the power keys 82 and function keys 81, respectively. In this embodiment, the power keys 82 and function keys 81 may be manufactured from substrates of any material. Because the displays 83 surround the outer rings of the power keys 82 and function keys 81, the light emitted by the displays 83 can be directly observed by the user with the naked eye.

[0031] One of the technical features of this invention is that when the usage time, number of uses, or output volume of the extractor 10 reaches a predetermined cleaning condition, the extractor 10 needs to be cleaned. In this case, the display 83 of the extractor 10 flashes to notify the user to clean the extractor 10. The flashing of the display 83 stops after the user has finished cleaning the extractor 10. To prevent the extractor 10 from being used continuously and drinks being produced before the user has finished cleaning, the processor 71 disables several function keys 81 if the extractor 10 needs to be cleaned but has not yet been cleaned. In other words, if the display 83 is flashing, several function keys 81 are disabled. In this case, no matter which function key 81 the user presses, it will not be possible to trigger the extractor 10 to produce a drink.

[0032] In one embodiment, the timer 73 is a physical timer installed inside the housing 11. In another embodiment, the timer 73 is a virtual timer implemented by the processor 71 using software. The timer 73 continuously records the length of the startup time of the extractor 10 from the time the extractor 10 is powered on and started up. In one embodiment, if the length of the startup time of the extractor 10 exceeds a predetermined length of time, the processor 71 determines that the extractor 10 needs to be cleaned, controls the display 83 to blink, and disables several function keys 81.

[0033] In one embodiment, the length of the predetermined time is 24 hours from the time the extraction machine 10 is powered on and started up, but the present invention is not limited thereto.

[0034] In one embodiment, the sensor 74 is installed inside the housing 11 and detects the action of the puncture needle 6 piercing the capsule 100. The sensor 74 is, for example, a microphone that detects the sound of the puncture needle 6 piercing the capsule 100, an image capture unit (e.g., a camera) that detects an image of the puncture needle 6 piercing the capsule 100, or an infrared sensing unit that detects an image of the puncture needle 6 being inserted into the capsule 100. The sensor 74 continuously records the amount of drink produced from the time the dispenser 10 is powered on and started up until the puncture needle 6 pierces the capsule 100.

[0035] In other embodiments, the processor 71 directly records the number of times each of the function keys 81 is pressed. By recording the number of times each of the function keys 81 is pressed, the processor 71 can directly obtain statistics on the amount of drinks produced by the dispenser 10.

[0036] In one embodiment, if the amount of drink produced by the extraction machine 10 exceeds a predetermined amount, the processor 71 determines that the extraction machine 10 needs to be cleaned, controls the display 83 to blink, and disables several function keys 81.

[0037] In one embodiment, the aforementioned predetermined amount is 2000 (the extraction machine 10 produces 2000 cups of drink), but the present invention is not limited to this.

[0038] In one embodiment, after the extractor 10 is powered on and started up, the processor 71 continuously records the total amount (ml) of liquid extracted by the extractor 10 and output from the beverage nozzle 18. In one embodiment, if the total amount of liquid extracted by the extractor 10 exceeds a predetermined extraction amount, the processor 71 determines that the extractor 10 needs to be cleaned, controls the display 83 to blink, and disables several function keys 81.

[0039] In one embodiment, the aforementioned predetermined extraction volume is 1 million ml (for example, the extraction machine 10 produces 2,000 cups of drink, and the average volume of one cup of drink is 500 ml), but the present invention is not limited thereto.

[0040] Figure 6 is a flowchart illustrating the prevention of human error in a capsule extractor according to one embodiment of the present invention. Specifically, Figure 6 shows a human error prevention mechanism according to the present invention that prohibits the continuous use of an extractor 10 that has not been thoroughly cleaned, and this human error prevention mechanism is applied to the extractor 10 shown in Figures 1 to 5.

[0041] In the example shown in Figure 6, first, the user presses the power key 82 to start the extraction machine 10 (see step S61). After the extraction machine 10 is started, the timer 73 or processor 71 starts recording the length of the startup time (see step S62). Next, the user places the capsule 100 into the capsule storage tank 15, closes the lid 4, punctures the capsule 100 with the puncture needle 6, and presses one of the function keys 81 to perform extraction from the capsule 100 and produce a drink (see step S63). At this time, the sensor 74 and processor 71 update the number of cups produced and the total amount of liquid extracted by the extraction machine 10 (see step S64). Then, the processor 71 determines whether one of the startup time of the extraction machine 10, the number of cups produced, or the total amount of liquid has exceeded one of the predetermined time, predetermined amount, or predetermined extraction amount (see step S65).

[0042] In step S65, if it is determined that the startup time does not exceed the predetermined time, the number of cups produced does not exceed the predetermined amount, and the total amount of liquid extracted does not exceed the predetermined extraction amount, the processor 71 returns to step S63 and waits, and the user triggers any of the function keys 61 to perform extraction again.

[0043] In step S65, if it is determined that the startup time exceeds a predetermined time, the number of cups produced exceeds a predetermined amount, or the total amount of liquid extracted exceeds a predetermined extraction amount, the processor 71 controls the display 83 to flash (see step S66) and notifies the user to clean the dispenser 10. From the time the display 83 starts flashing, the processor 71 continuously determines whether the user has performed a cleaning operation on the dispenser 10 (see step S67). The cleaning operation includes manual cleaning by the user and automatic cleaning of the dispenser 10.

[0044] Before the cleaning of the extraction machine 10 is complete, the processor 71 disables the multiple function keys 81 (see step S68) and returns to step S67 to wait and make a decision. In this case, the multiple function keys 81 become unusable. After the cleaning of the extraction machine 10 is complete, the processor 71 enables the multiple function keys 81 (see step S69) and returns to step S63 to wait. In this case, the user can perform extraction again by triggering any one of the function keys 61.

[0045] This invention prevents human error by making it impossible to continue using the capsule dispenser until cleaning is complete. This prevents the potential risk of users continuing to produce drinks without cleaning, which could affect the quality of the drinks and ultimately damage the capsule dispenser.

[0046] The embodiments described above are provided to facilitate understanding of the present invention and are not intended to limit its interpretation. The present invention may be modified or improved without departing from its spirit, and it goes without saying that equivalents thereof are included. [Explanation of symbols]
