  The following description and the drawings referred to are provided for those skilled in the art to understand the present disclosure, and are not intended to limit the scope of the claims of the present disclosure.

<Description of appearance of dispensing device 1>
FIG. 1 is a diagram illustrating an appearance of the dispensing device 1. As shown in FIG. 1, the pouring device 1 has a hot water storage unit 100 and a pouring unit 200, and a tube 300 is connected between them. Although not particularly illustrated, the hot water storage unit 100 and the pouring unit 200 are electrically connected by, for example, a cable or the like, and from the hot water storage unit 100 to the pouring unit 200, or from the pouring unit 200 to the hot water storage unit 100. Can be supplied.

  The hot water storage unit 100 stores hot water while appropriately controlling the temperature, and transfers the hot water to the pouring unit 200 through the tube 300 as necessary. The hot water storage unit 100 is an example of the liquid storage unit of the present disclosure. The pouring unit 200 pours hot water transferred from the hot water storage unit 100 into, for example, coffee beans in the dripper. The pouring unit 200 pours hot water transferred from the hot water storage unit 100 into, for example, coffee beans in the dripper. Put out. Thereby, coffee is extracted. The tube 300 is formed of a heat-insulating material such as silicon, for example, and transfers the hot water from the hot water storage unit 100 to the pouring unit 200 so as not to be cooled as much as possible. The tube 300 is an example of piping according to the present disclosure. In the present embodiment, in order to improve the installation flexibility of the pouring device 1, the hot water storage section 100 and the pouring section 200 are arranged at a distance from each other, and the length of the tube 300 is, for example, about several meters. It is assumed that it can be changed.

<Configuration of hot water storage unit 100>
FIG. 2 is a diagram illustrating the configuration of the hot water storage unit 100. FIG. 3 is a cross-sectional perspective view illustrating the internal configuration of the hot water storage unit 100.

  As shown in FIG. 2, the hot water storage unit 100 includes a tank 101, a float 102, a float switch 103, a water supply unit 104, a water supply pipe 105, a heater 106, a surplus water discharge port 107, an overflow pipe 108, a first boiling detection unit 109, Second boiling detector 110, surplus water tank 111, partition plate 112, first water temperature detector 113, second water temperature detector 114, intake port 115, intake pipe 116, pump 117, flow meter 118, three-way valve 119, agitation A working tube 120 is provided.

  The tank 101 is a heat-resistant tank that can store high-temperature hot water, and includes a box-shaped tank body 1011 and an upper lid 1012 that covers an upper surface opening of the tank body 1011. A float 102 that moves up and down in conjunction with the water level in the tank 101 is provided above the tank 101. The float 102 is formed in a hollow shape so as to float on the water surface by a material such as metal or resin. Further, a support rod 1021 is provided at the upper part of the float 102, and when the float 102 moves up and down in conjunction with the water level in the tank 101, the support rod 1021 comes into contact with the float switch 103. The upper lid 1012 of the tank 101 is provided with a hole (not shown) through which the support rod 1021 of the float 102 passes.

  The float switch 103 includes an upper limit water level switch 1031 corresponding to the position of the float 102 at the upper limit water level of the tank 101, and a lower limit water level switch 1032 corresponding to the position of the float 102 at the lower limit water level of the tank 101. The upper limit water level switch 1031 is provided at a position in contact with the support rod 1021 when the float 102 is at the upper limit water level of the tank 101, and the lower limit water level switch 1032 is supported when the float 102 is at the lower limit water level of the tank 101. It is provided at a position in contact with the rod 1021. With such a configuration, the float switch 103 detects that the water level in the tank 101 has reached the upper limit water level or the lower limit water level. When the upper limit water level switch 1031 or the lower limit water level switch 1032 of the float switch 103 detects the upper limit water level or the lower limit water level, the detection result is transmitted to a control unit 130 (not shown in FIGS. 2 and 3) described later.

  The water supply unit 104 is a tubular member that is connected to, for example, a water supply and supplies water having a temperature lower than that of hot water in the tank into the tank 101. The water supply unit 104 supplies the amount of water requested by the control unit 130 into the tank 101 under the control of the control unit 130 described later. The water supply unit 104 may include a filter, a water purifier, and the like (not shown), and may purify the water supplied to the tank 101. The front end of the water supply unit 104 on the tank side is exposed at a position higher than the upper limit water level in the tank 101. The upper lid 1012 of the tank 101 is provided with a hole (not shown) through which the water supply unit 104 passes.

  As shown in FIG. 2, all of the water supplied from the water supply unit 104 flows into the water supply pipe 105 located at the extension of the tip of the water supply unit 104 on the tank 101 side. The front end of the water supply unit 104 on the tank 101 side and the inlet 1051 of the water supply pipe 105 have a predetermined interval (for example, an interval of 25 mm or more) to prevent backflow of water, and the inlet 1051 of the water supply pipe 105 is The water supply pipe 105 is fixed in the tank 101 so as to be higher than the upper limit water level of the tank 101. The outlet 1052 of the water supply pipe 105 is open near the bottom surface of the tank 101 as shown in FIG.

  The heater 106 heats the water stored in the tank 101 to hot water under the control of the control unit 130 described later. The heater 106 is a sheathed heater, for example. The heater 106 is attached to the upper lid 1012 of the tank 101 and extends to the vicinity of the bottom surface of the tank 101 (more specifically, the vicinity of the upper surface of a partition plate 112 described later) as shown in FIG. The heater 106 includes a non-heat generating portion 1061 that is a portion that does not generate heat and a heat generating portion 1062 that is a portion that generates heat. In the heater 106 inserted into the tank 101, the non-heat generating portion 1061 extends from the upper lid 1012 of the tank 101 to below the lower limit water level, and the heat generating portion 1062 is a portion below the lower end of the non-heat generating portion 1061. . Therefore, the heat generating part 1062 is immersed in the hot water stored in the tank 101. Thereby, empty cooking can be prevented.

  The surplus water discharge port 107 is a hole provided at a position slightly higher than the upper limit water level of the tank 101, and an overflow pipe 108 is connected thereto. When the hot water stored in the tank 101 exceeds the upper limit water level for some reason, surplus hot water (surplus water) is discharged from the surplus water discharge port 107. Alternatively, when the hot water in the tank 101 boils, steam generated from the hot water is discharged from the surplus water discharge port 107. Similarly to the inlet 1051 of the water supply pipe 105 described above, the surplus water discharge port 107 has a predetermined distance (for example, an interval of 25 mm or more) with respect to the front end of the water supply unit 104 on the tank 101 side to prevent backflow. It is desirable to be arranged.

  The overflow pipe 108 is a pipe for discarding excess water. The tip of the overflow pipe 108 opposite to the surplus water discharge port 107 is connected to a surplus water tank 111, and surplus water in the tank 101 is stored in the surplus water tank 111. The surplus water tank 111 can be arbitrarily removed by the user of the pouring device 1, and the surplus water stored in the surplus water tank 111 is appropriately discarded by the user of the pouring device 1.

  The overflow pipe 108 has a first boiling detector 109 in the vicinity of the middle thereof, and a second boiling detector 110 in the vicinity of the connection portion (terminal portion) with the surplus water tank 111. In the above description, the position of the first boiling detector 109 is near the middle of the overflow pipe 108. However, in order to increase the detection speed, the first boiling detector 109 may be arranged slightly closer to the tank 101 than the middle of the overflow pipe 108. .

  FIG. 4 is a diagram illustrating the first boiling detection unit 109. As shown in FIG. 4, the first boiling detector 109 has a configuration in which a temperature sensor 1092 is attached to a pipe portion 1091. The pipe portion 1091 is a tubular member that constitutes a part of the overflow pipe 108. The pipe portion 1091 may be configured integrally with other parts of the overflow pipe 108, or may be configured separately and connected to other parts of the overflow pipe 108.

  The temperature sensor 1092 has a configuration in which, for example, a thermistor is held by a screw-like member, and the tip of the screw-like member is inserted into a hole (not shown) provided in the pipe portion 1091 and fixed. And the thermistor exposed from the front-end | tip part of a screw-shaped member is warmed by the surplus water or steam which passes the inside of the pipe part 1091. With such a configuration, the temperature sensor 1092 can detect the temperature of excess water or steam. The temperature sensor 1092 transmits the detected temperature of excess water or steam to the control unit 130 described later. As will be described in detail later, the control unit 130 stops heating by the heater 106 when the temperature of the thermistor of the first boiling detection unit 109 becomes a predetermined temperature or higher due to excess water or steam. The predetermined temperature is a temperature of the first boiling detection unit 109 heated by the steam generated by boiling in the tank 101, and is 83 ° C., for example.

  The second boiling detection unit 110 has a configuration in which, for example, a bimetal thermostat is attached to a pipe connected to the overflow pipe 108. As excess water or steam in the overflow pipe 108 passes through the pipe, the temperature of the bimetal thermostat increases accordingly. When the bimetal thermostat reaches a predetermined temperature or higher, the power supply to the heater 106 is physically cut off regardless of the control of the control unit 130. The predetermined temperature is, for example, 83 ° C., similar to the first boiling detector 109 described above.

  With such a configuration, the heater 106 prevents the hot water in the tank 101 from continuing to boil. Preferably, the bimetal thermostat included in the second boiling detector 110 is a manual return type. As a result, when the bimetal thermostat that has reached a predetermined temperature or more is cut off, the heater 106 does not heat the hot water in the tank 101 unless it is restored by the user of the pouring device 1. The situation where the hot water continues to boil is more preferably avoided.

  As described above, in the pouring device 1 according to the embodiment of the present disclosure, the hot water storage unit 100 includes two boiling detection units, and performs boiling detection using different methods. The first boiling detection unit 109 has a configuration in which the thermistor is exposed in the pipe unit 1091, and the first boiling detection unit 109 is located upstream of the overflow pipe 108 from the second boiling detection unit 110, and is boiling. Therefore, when the hot water in the tank 101 has boiled, the boiling detection is faster than the second boiling detection unit 110. In this embodiment, the detection temperature of the first boiling detection unit 109 and the second boiling detection unit 110 are the same, but the detection temperature of the first boiling detection unit 109 is higher than the detection temperature of the second boiling detection unit 110. It may be low. In this case, when the hot water in the tank 101 further boils, the second boiling detection unit 110 detects the boiling earlier.

  In the normal operation of the dispensing apparatus 1, since the heating of the heater 106 is stopped when the first boiling detector 109 detects boiling, the boiling of hot water in the tank 101 stops and the second boiling detector 110 boils. Will not be detected. Only when the first boiling detector 109 cannot detect boiling of hot water in the tank 101 for some reason, the second boiling detector 110 detects boiling, the bimetal thermostat is cut off, and the power supply to the heater 106 is physically performed. Is blocked. In other words, the second boiling detection unit 110 does not operate in the normal operation of the dispensing device 1, and plays a role like a safety device in an abnormal state, that is, when the first boiling detection unit 109 does not operate. .

  As shown in FIGS. 2 and 3, the partition plate 112 is a plate-like member provided in the tank 101. As shown in FIGS. 2 and 3, the outlet 1052 of the water supply pipe 105 is disposed below the tank 101 with respect to the partition plate 112. In addition, the lower end of the heat generating portion 1062 of the heater 106 is disposed at a position away from the partition plate 112 by a predetermined distance (for example, 5 mm).

  With such a configuration, the water supplied by the water supply unit 104 is discharged from the outlet 1052 of the water supply pipe 105 to the lower side than the partition plate 112 in the tank 101. Accordingly, the water present below the partition plate 112 in the tank 101 is kept at a relatively low temperature because it is not easily heated by the heat generating portion 1062 of the heater 106 due to the partition plate 112. On the other hand, relatively hot water heated by the heat generating portion 1062 of the heater 106 exists above the partition plate 112 in the tank 101. Hereinafter, the hot water existing above the partition plate 112 in the tank 101 may be simply referred to as hot water in the tank 101. Further, water existing below the partition plate 112 in the tank 101 may be simply referred to as water in the tank 101.

  As illustrated in FIG. 3, the partition plate 112 may be provided with holes or openings. The holes and openings provided in the partition plate 112 are not limited to the positions and shapes illustrated in FIG. 3. For example, the openings may be provided on both sides of the partition plate 112.

  The partition plate 112 is provided at a position near the bottom surface of the tank 101 between the lower limit water level of the tank 101 and the bottom surface of the tank 101. Depending on the position of the partition plate 112, the amount of hot water present above the partition plate 112 is greater than the amount of water present below the partition plate 112. Specifically, for example, the partition plate 112 is arranged so that the capacity above the partition plate 112 of the tank 101 is 5.5 l and the capacity below the partition plate 112 is about 2.0 l.

  The 1st water temperature detection part 113 and the 2nd water temperature detection part 114 are temperature sensors, detect the temperature of the hot water or water in the tank 101, and transmit to the control part 130 mentioned later. As shown in FIGS. 2 and 3, the sensor unit of the first water temperature detection unit 113 is above the partition plate 112 of the tank 101, and the sensor unit of the second water temperature detection unit 114 is below the partition plate 112 of the tank 101. , Each is arranged. Accordingly, the first water temperature detection unit 113 detects the temperature of hot water existing in the tank 101 above the partition plate 112 (hereinafter referred to as hot water temperature), and the second water temperature detection unit 114 includes the partition plate 112 in the tank 101. The temperature of water existing below (hereinafter, water temperature) is detected.

  The water intake 115 is an opening for taking hot water in the tank 101, and a water intake pipe 116 is connected to the water intake 115. The water intake 115 is disposed below the lower limit water level of the tank 101 and sufficiently above the partition plate 112. Thereby, the temperature of the hot water taken from the water intake 115 becomes substantially equal to the hot water temperature detected by the first water temperature detection unit 113. A pump 117 is provided near the water intake 115 of the water intake pipe 116. The pump 117 operates under the control of the control unit 130, sucks out hot water in the tank 101, and transfers the hot water to the pouring unit 200 through the tube 300 connected to the downstream side of the water intake pipe 116.

  A flow meter 118 is provided on the downstream side of the intake pipe 116 from the pump 117 (on the tube 300 side). The flow meter 118 transmits information related to the flow rate of hot water flowing through the intake pipe 116 to the control unit 130. For example, hot water flowing through the intake pipe 116 flows to the flow meter 118, and pulse information is transmitted to the control unit 130 for each predetermined amount of hot water.

  A three-way valve 119 is provided on the downstream side of the flow meter 118 of the intake pipe 116. The three-way valve 119 connects the upstream side, the downstream side, and the stirring pipe 120 of the intake pipe 116. The three-way valve 119 is, for example, an electromagnetic valve, and changes the flow path under the control of the control unit 130. Specifically, when the stirring pipe 120 side of the three-way valve 119 is closed under the control of the control unit 130, a flow path that flows from the upstream side to the downstream side of the water intake pipe 116 is formed. On the other hand, when the downstream side of the intake pipe 116 in the three-way valve 119 is closed by the control of the control unit 130, a flow path that flows from the stirring pipe 120 through the three-way valve 119 to the upstream side of the intake pipe 116 is formed. As a configuration for changing the flow path of the hot water flowing through the intake pipe 116, an electromagnetic valve may be provided on each of the upstream side, the downstream side, and the stirring pipe 120 of the intake pipe 116 instead of the three-way valve 119. . In this case, the flow path is changed by the control unit 130 controlling each of the three electromagnetic valves.

  The stirring tube 120 is a tubular member, one connected to the three-way valve 119 and the other connected to the lower side of the partition plate 112 of the tank 101.

<Operation of hot water storage unit 100>
Next, the operation of each component of the hot water storage unit 100 will be described. Each component of the hot water storage unit 100 described above operates under the control of the control unit 130. FIG. 5 is a diagram illustrating a control block of the hot water storage unit 100.

  The control unit 130 is a control block for controlling the operation of each component of the hot water storage unit 100. Although not shown in FIGS. 2 and 3, control unit 130 is provided inside hot water storage unit 100. The control unit 130 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory) storing a control program, and a working memory such as a RAM (Random Access Memory). The CPU reads out the control program from the ROM and develops it in the RAM, and controls the operation of each component of the hot water storage unit 100 in cooperation with the developed control program.

  As shown in FIG. 5, the control unit 130 includes a float switch 103, a first boiling detection unit 109, a first water temperature detection unit 113, a second water temperature detection unit 114, a flow meter 118, an operation unit 131 to be described later, and an operation unit to be described later. Operation control of the water supply unit 104, the heater 106, the pump 117, and the three-way valve 119 is performed using at least one of the information transmitted from the control unit 240 of the dispensing unit 200. Below, the control which the control part 130 performs according to each information is demonstrated.

[Water level control]
The control unit 130 refers to the upper limit water level detection result from the upper limit water level switch 1031 of the float switch 103, and receives water supply from the water supply unit 104 depending on whether or not the current water level in the tank 101 is the upper limit water level. Decide whether or not.

  Specifically, while the upper limit water level detection result from the upper limit water level switch 1031 is received, the control unit 130 stops the operation of the water supply unit 104 and detects the upper limit water level because the inside of the tank 101 is at the upper limit water level. When the result is not received, the hot water in the tank 101 is no longer the upper limit water level, and the water supply unit 104 is controlled to supply water.

  By such control, for example, when hot water in the tank 101 is transferred to the pouring unit 200, when the water level in the tank 101 falls from the upper limit water level, water is supplied into the tank 101 by the water supply unit 104. For this reason, the water level in the tank 101 is always kept at the upper limit water level.

[Control of hot water transfer]
The control unit 130 controls the pump 117 based on the hot water supply instruction information received from the control unit 240 of the pouring unit 200 and transfers the hot water in the tank 101 to the pouring unit 200. The hot water supply instruction information includes information related to the amount of hot water requested by the pouring unit 200, and the control unit 130 receives the intake pipe received from the flow meter 118 so as to transfer hot water by the required amount. Information about the flow rate through 116 is used to control pump 117. Details of the hot water supply instruction information will be described in the description of the dispensing unit 200. In the present embodiment, the discharge direction of the pump 117 when the pump 117 transfers hot water from the intake port 115 through the intake pipe 116 and the tube 300 to the extraction unit 200 is referred to as a forward direction.

  By such control, hot water required in the pouring part 200 is transferred to the pouring part 200 without excess or deficiency.

[Control for preheating the tube 300]
The control unit 130 controls the pump 117 based on preheating instruction information (described later) received from the control unit 240 of the dispensing unit 200 to transfer a predetermined amount of hot water in the tank 101 into the tube 300. The hot water used for preheating the tube 300 may be discarded in the pouring unit 200 as it is, or may be used to warm a beverage container used for extracting coffee in the pouring unit 200. Alternatively, the controller 130 may operate the pump 117 in the reverse direction so that hot water remaining in the tube 300 after preheating the tube 300 is returned to the tank 101. Note that the predetermined amount may be as little hot water as possible with the amount of heat sufficient to heat the entire tube 300, and the method for determining the predetermined amount is not particularly limited in the present disclosure.

[Control on hot water temperature in tank 101]
The control of the control unit 130 regarding the temperature of the hot water in the tank 101 differs depending on whether or not the set temperature is set lower than the boiling point. The set temperature is a temperature at which hot water in the tank 101 should be kept. The set temperature is set by the control unit 130 based on an operation by the user of the dispensing device 1 via the operation unit 131. The control unit 130 stores the set temperature in a memory or the like (not shown).

  The operation unit 131 is an input device such as a button, a switch, or a touch panel provided on the outer surface of the hot water storage unit 100 (not shown in FIGS. 1 to 3). Alternatively, the operation unit 131 may be configured to be able to communicate with the control unit 130 by wired or wireless communication like a remote control switch and to be separable from the main body of the hot water storage unit 100. For example, the operation unit 131 receives an operation input by a user of the dispensing device 1 and transmits operation information regarding the content of the operation input to the control unit 130. Specifically, the content of the operation input received by the operation unit 131 is, for example, the extraction of coffee when the set temperature of hot water in the tank 101 is lower than the set temperature (the hot water is not boiling). It is the lower limit temperature at which the transfer of hot water to the pouring part 200 is stopped as impossible.

(1) When the set temperature is not set lower than the boiling point When the set temperature is not set lower than the boiling point, in other words, the set temperature is not set or the set temperature is set to a temperature higher than the boiling point. If it is, the control unit 130 performs the following control. The case where the set temperature is set to a temperature equal to or higher than the boiling point occurs, for example, when the boiling point is lowered due to a change in atmospheric pressure, such as when the pouring device 1 is installed at a high place. In this case, the boiling point is 95 ° C, the set temperature is 97 ° C, and the like.

  The control unit 130 receives the temperature (hot water temperature) of hot water existing above the partition plate 112 in the tank 101 from the first water temperature detection unit 113, and determines whether or not the received hot water temperature is lower than the set temperature. To do. When the received hot water temperature is lower than the set temperature, the heater 106 is controlled until the hot water temperature in the tank 101 reaches the set temperature, and heating is performed. Even when the set temperature is not set, the control unit 130 similarly controls the heater 106 to perform heating.

  Here, since the case where the set temperature is not set or the set temperature is set higher than the boiling point is described, the heater 106 continues to heat, so that the hot water temperature in the tank 101 becomes the boiling point. Over and boil.

  The control unit 130 determines that the hot water in the tank 101 is boiling when the temperature of the first boiling detection unit 109 provided in the overflow pipe 108 is equal to or higher than a predetermined temperature (for example, 83 ° C.).

  When the temperature detected by the temperature sensor 1092 of the first boiling detection unit 109 is equal to or higher than a predetermined temperature, the control unit 130 determines that the hot water in the tank 101 is boiling, controls the heater 106, and controls the tank 101. Stop heating the hot water inside. In addition, when the temperature detected by the temperature sensor 1092 of the first boiling detection unit 109 is lower than the predetermined temperature, the control unit 130 does not determine that the hot water in the tank 101 is boiling and operates the heater 106. The hot water in the tank 101 is heated.

  That is, the control unit 130 controls the heater 106 to always heat the hot water when it is determined that the hot water in the tank 101 is not boiling, and to stop heating when it is determined that the water has boiled. By such control, the hot water in the tank 101 frequently repeats a boiling state and a non-boiling state, and the hot water temperature is maintained at a temperature immediately before boiling. With such a configuration, the hot water in the tank 101 can be kept as high as possible while avoiding the danger of the hot water in the tank 101 continuing to boil.

  For example, when the first boiling detection unit 109 cannot detect boiling of hot water in the tank 101 due to a failure of the first boiling detection unit 109, a disconnection between the first boiling detection unit 109 and the control unit 130, or the like. The second boiling detector 110 detects boiling and forcibly stops the heater 106. Specifically, as described above, when the temperature of the excess water or steam in the overflow pipe 108 is equal to or higher than the predetermined temperature, the second boiling detection unit 110 sends the heater 106 to the heater 106 regardless of the control of the control unit 130. Physically cut off the power supply. And if the temperature of the surplus water or steam in the overflow pipe | tube 108 becomes more than predetermined temperature and the 2nd boiling detection part 110 cuts out once, unless it returns by the user of the pouring device 1, it will be in the tank 101 by the heater 106. The hot water is not heated, and the situation where the hot water in the tank 101 keeps boiling is preferably avoided.

  In this way, when the set temperature is not set lower than the boiling point, the control unit 130 performs control so that the hot water in the tank 101 is kept as high as possible (close to the boiling point).

(2) When a set temperature lower than the boiling point is set When a set temperature lower than the boiling point is set, specifically, for example, when the set temperature is 97 ° C. when the boiling point is 100 ° C., control is performed The unit 130 performs the following control.

  The control unit 130 receives the temperature (hot water temperature) of hot water existing above the partition plate 112 in the tank 101 from the first water temperature detection unit 113, and determines whether or not the received hot water temperature is lower than the set temperature. To do. When the received hot water temperature is lower than the set temperature, the control unit 130 controls the heater 106 until the hot water temperature in the tank 101 reaches the set temperature, so that heating is performed. On the other hand, the control unit 130 stops the heating of the heater 106 when the received hot water temperature is equal to or higher than the set temperature.

  And control part 130 performs control which lowers the temperature of the hot water which exists above partition plate 112 using the water which exists below partition plate 112, when the received hot water temperature is more than preset temperature.

  Specifically, the control unit 130 operates the pump 117 in the reverse direction, closes the downstream side of the water intake pipe 116 of the three-way valve 119, and removes water existing below the partition plate 112 from the stirring pipe 120. The water is sucked up and flows upstream of the intake pipe 116. Thereby, the relatively low temperature water existing below the partition plate 112 is supplied from the water intake 115 into the relatively high temperature hot water above the partition plate 112 in the tank 101.

  The control unit 130 supplies a relatively low temperature to the tank 101 based on the set temperature, the hot water temperature received from the first water temperature detection unit 113, and the water temperature received from the second water temperature detection unit 114. Calculate the amount of water. This calculation method is not particularly limited in the present embodiment. Then, the control unit 130 controls the pump 117 so as to supply relatively low temperature water into the tank 101 by the calculated amount while referring to the flow rate of the water flowing through the intake pipe 116 received from the flow meter 118. .

  By such control, water present below the partition plate 112 is transferred from the water intake 115 to the hot water layer present above the partition plate 112 in the tank 101, so that relatively low-temperature water is The hot water existing above the partition plate 112 is lowered by being mixed with relatively hot water. Thereby, the temperature of the hot water existing above the partition plate 112 is adjusted to the set temperature. If the first water temperature detection unit 113 detects that the set temperature has been reached, the control unit 130 may end the control even during the control.

<Description of the dispensing unit 200>
Next, the extraction unit 200 will be described. FIG. 6 is a perspective view showing the appearance of the extraction unit 200. As shown in FIG. 6, the pouring unit 200 includes an upper structure 201, two columns 202 and 203, a base 204, a dripper base 205, an operation unit 206, a hot water supply availability switch 207, a drain port 208, a drain groove 209, and a nozzle. A unit 210 is included. In the following description of the extraction unit 200, as shown in FIG. 6, the front side of the extraction unit 200 in FIG. 6 is defined as front, the right side is right, and the upper side is up.

  As shown in FIG. 6, the pouring part 200 has two columns 202 and 203 provided at almost right and left ends of the base 204, and an upper structure 201 provided at the upper ends of the two columns. The shape is as follows. A nozzle unit 210 for spraying hot water is provided near the left and right center of the upper structure 201.

  A dripper table 205 is provided near the vertical center of the two columns 202 and 203. A circular hole is provided in the center of the dripper base 205, and a funnel-shaped dripper 2051 (see FIGS. 10A and 10B described later) is disposed. In the present embodiment, the extraction unit 200 is described as including the dripper 2051, but the present disclosure is not limited to this, and the extraction unit 200 may not include the dripper 2051. Any dripper can be used as long as it has a funnel shape of a size that is fitted into and fixed to the hole of the dripper base 205.

  The operation unit 206 is an input device such as a button, a switch, or a touch panel, for example, and receives an operation input from the user of the dispensing apparatus 1. Specifically, the contents of the operation input received by the operation unit 206 include specifying the amount of hot water sprayed from the nozzle unit 210 and setting the tube 300 so that the hot water transferred from the hot water storage unit 100 is not cooled by the tube 300. Instructions to preheat. The operation unit 206 transmits operation information regarding the contents of the received operation input to the control unit 240 described later.

  The hot water supply availability switch 207 is, for example, an on / off switch, and is a switch for setting the availability of hot water supply from the nozzle unit 210 in the pouring unit 200. That is, in the state where the hot water supply availability switch 207 is off, the pouring unit 200 does not pour hot water from the nozzle unit 210 regardless of the operation input of the user of the pouring device 1 to the operation unit 206.

  The drainage port 208 has a hole-type configuration provided immediately below the hole of the dripper base 205, and is covered with a gap that allows hot water to pass as shown in FIG. Although illustration is omitted, when the dripper 2051 is arranged on the dripper stand 205 and coffee is extracted, a beverage container (cup or the like) is placed on the lid of the drain port 208, and the extracted coffee is used as the beverage container. Injected into. The drain port 208 allows hot water spilled from the nozzle unit 210 and the dripper stand 205 to flow into the drain groove 209, for example. The drainage groove 209 is a groove for discharging hot water spilled into the drainage port 208.

  Although details will be described later, the nozzle unit 210 sprays hot water on the ground coffee beans placed in a dripper 2051 (see FIG. 10A described later) disposed in a hole of the dripper base 205. Thereby, coffee is extracted.

  The tube 300 connected to the hot water storage unit 100 is connected to the pouring unit 200 and transfers hot water from the hot water storage unit 100. Although the position of the extraction part 200 to which the tube 300 is connected is not particularly limited in the present disclosure, it may be connected to the rear surface side of the base 204 as shown in FIG.

<Internal structure of extraction part 200>
[Purpose of this disclosure]
In the pouring device 1 according to the embodiment of the present disclosure, as described above, the hot water storage unit 100 and the pouring unit 200 are arranged at positions separated from each other in order to improve the degree of freedom of installation of the pouring device 1. Is assumed. In such a pouring device 1, there is a desire to install the pouring part 200 in a limited space. In order to realize such a demand, it is necessary to reduce the size of the extraction portion 200.

  In addition, in order to extract high-quality coffee, it is desirable that hot water is uniformly sprayed on ground coffee beans put in a dripper. As a conventional method of spraying hot water as uniformly as possible to ground coffee beans put in a dripper, there is one using a shower-like nozzle unit. However, when hot water is supplied by a shower-like nozzle unit, the position of the nozzle hole is constant, so the position where the shower-like hot water hits the ground beans is also constant. For this reason, in order to perform high-quality coffee extraction, it is desired to improve how hot water hits ground beans.

  That is, the present disclosure aims to form the extraction portion 200 as small as possible. Another object of the present disclosure is to improve how hot water hits ground beans put in a dripper. Below, the structure of the extraction | pouring part 200 for making the magnitude | size of the extraction | pouring part 200 as small as possible and improving the contact method of hot water with respect to a ground bean is demonstrated in detail.

[Details of internal structure]
FIG. 7 is a perspective view for explaining the internal structure of the upper structure 201, the column 203, and the base 204 of the extraction unit 200. In FIG. 7, the outer walls of the upper structure 201, the column 203, and the base 204 are seen through. In addition, in FIG. 7, the extraction | pouring part 200 is seen from the back side contrary to FIG.

  A motor 221 is provided immediately below the column 203 in the base 204. The motor 221 is disposed so that the rotation axis is parallel to the vertical direction of the extraction unit 200. One end of a shaft 222 disposed inside the column 203 is connected to the rotation shaft of the motor 221. The other end of the shaft 222 is connected to the rotation center of a pulley 223 provided in the upper structure 201. A belt 224 is hung on the pulley 223 and a pulley 225 disposed near the center of the upper structure 201. A nozzle head support portion 230 to be described later is provided at the center of the pulley 225. The motor 221 rotates under the control of the control unit 240 described later. The pulley 223 is an example of a first pulley, and the pulley 225 is an example of a second pulley.

  With such a configuration, when the motor 221 rotates, the pulley 223 rotates through the shaft 222, and the rotation of the pulley 223 is transmitted to the pulley 225 by the belt 224. Thereby, the nozzle head 231 (details will be described later) supported by the nozzle head support portion 230 rotates. The nozzle head support 230 and the nozzle head 231 correspond to the nozzle unit 210 described above.

  Connected to the nozzle head 231 is a hot water supply pipe 226 that passes through the inside of the upper structure 201 and the support column 202 (illustration of the hot water supply pipe 226 inside the support column 202 is omitted). The hot water supply pipe 226 is connected to the tube 300 and transfers the hot water transferred from the hot water storage unit 100 to the nozzle head 231.

  FIG. 8 is a cross-sectional view of the nozzle head support portion 230 and the nozzle head 231 (that is, the nozzle unit 210) provided near the center of the upper structure 201. 8 is a cross-sectional view taken along the left-right direction of FIG.

  As shown in FIG. 8, a circular hole is formed at the center of the pulley 225, and the pulley 225 rotates around the center of the hole. In the hole of the pulley 225, a nozzle head support portion 230 that connects the hot water supply pipe 226 and the nozzle head 231 so as to communicate with each other is disposed. The nozzle head support portion 230 rotates integrally with the pulley 225.

  More specifically, the nozzle head support portion 230 is formed in a tubular shape, and is disposed inside the upper structure 201 such that the lower side of the tube is exposed to the outside from a bearing 233 provided on the lower surface of the upper structure 201. One end of the hot water supply pipe 226 is fitted from the upper end of the nozzle head support portion 230 to the middle of the pipe. A part (protrusion 2311 described later) of the nozzle head 231 is detachably screwed and fixed from the middle to the lower end of the tube of the nozzle head support portion 230. A seal member 2261 such as an O-ring is provided near one end of the hot water supply pipe 226 to prevent leakage. Similarly, a seal member 2315 is provided on the convex portion 2311 of the nozzle head 231.

  With such a configuration, when the nozzle head 231 is mounted on the nozzle head support portion 230, hot water is supplied into the nozzle head 231 through the hot water supply pipe 226. Further, when the pulley 225 is rotated by the rotation of the motor 221, the pulley 225, the nozzle head support part 230, and the nozzle head 231 screwed to the nozzle head support part 230 rotate together. The rotation center of the nozzle head 231 coincides with the center of the dripper 2051 disposed on the dripper base 205.

[Details of nozzle head]
FIG. 9 is a diagram for explaining the nozzle head 231. FIG. 9 is a cross-sectional view along the longitudinal direction of the nozzle head 231. The convex part 2311 on the upper side of the nozzle head 231 in FIG. 9 is a part screwed into the nozzle head support part 230 and is formed in a tubular shape. The convex portion 2311 is provided at a substantially central portion in the longitudinal direction of the nozzle head 231.

  The nozzle head body 2312 is formed in a tubular shape in which one end (the right side in FIG. 9) is released and the other end (the left side in FIG. 9) is sealed. A hole 2313 is provided on the lower surface near the end of the sealed side of the nozzle head body 2312. In addition, although the case where the number of the holes 2313 is three is illustrated in FIG. 9, this disclosure does not particularly limit the number of holes.

  Further, as shown in FIG. 9, a stopper 2314 is screwed into the released other end of the nozzle head body 2312. The stopper 2314 is provided with a seal member 2316 to prevent leakage.

  With such a configuration, when the convex portion 2311 is screwed into the nozzle head support portion 230 and hot water is supplied from the hot water supply pipe 226, hot water that has passed through the convex portion 2311 and the nozzle head main body 2312 passes through the hole 2313. Sprayed on. Hot water sprayed from the hole 2313 is poured into a dripper 2051 disposed in a hole of a dripper base 205 described later.

  Since the hole 2313 of the nozzle head 231 is provided in the vicinity of the end on one end side of the nozzle head main body 2312 sealed as shown in FIG. 9, the nozzle head 231 is rotated by the rotation of the motor 221. And the position where hot water sprayed from the hole 2313 is poured also rotates.

  Further, the nozzle head 231 can be detached from the nozzle head support portion 230, and when the stopper 2314 is pulled out with the nozzle head 231 removed from the nozzle head support portion 230, the tubular inner wall surface of the nozzle head main body 2312 is removed. It can be easily cleaned with a rod-shaped cleaning tool (not shown).

  10A and 10B are diagrams for explaining hot water sprayed from the nozzle head 231. FIG. 10A shows a cross section along a vertical line (vertical line in FIGS. 6 and 7) passing through the rotation center of the nozzle head 231.

  As shown in FIG. 10A, the respective components are arranged so that the center of the nozzle head 231 and the center of the hole provided in the dripper base 205 coincide. Moreover, the hole 2313 of the nozzle head 231 is provided so that the hot water sprayed from the nozzle head 231 is poured into the inside of the dripper 2051 formed in the funnel shape, which is disposed in the hole of the dripper base 205. More preferably, the hot water sprayed from the outermost hole among the holes 2313 of the nozzle head 231 is dropped directly on the ground coffee beans put in the dripper 2051, not on the wall surface portion of the dripper 2051. As described above, the hole 2313 of the nozzle head 231 is desirably provided.

  When the nozzle head 231 is rotated by the rotation of the motor 221, the locus of hot water sprayed from the hole 2313 is as shown in FIG. 10B. FIG. 10B is a view of the locus of hot water poured into the dripper 2051 as viewed from above the dripper 2051. Of the concentric circles shown in FIG. 10B, the outermost circle is the upper edge portion of the funnel shape of the dripper 2051, and the three inner circles are respectively from the three holes 2313 of the nozzle head 231 illustrated in FIG. It shows the trajectory of the hot water sprayed. As shown in FIG. 10B, the hot water sprayed from the nozzle head 231 is poured concentrically into the dripper 2051. For this reason, since hot water is poured evenly into ground beans (coffee beans) prepared in advance in the dripper 2051, high-quality coffee is extracted.

  The nozzle head 231 described above is an example of a nozzle head screwed into the nozzle head support portion 230, and the present disclosure is not limited to this. That is, the nozzle head may have various shapes other than the nozzle head 231 described above.

  FIG. 11A and FIG. 11B are diagrams for explaining a shower head 232 that sprays hot water in a shower shape as a modified example of the nozzle head. FIG. 11A is an enlarged cross-sectional view of the shower head 232. As shown in FIG. 11A, the bottom surface of the shower head 232 has a funnel shape that descends from the edge portion toward the rotation center portion, and a hole 2321 is appropriately provided on the funnel-shaped slope. The hole 2321 provided in the funnel-shaped slope is slanted with respect to the horizontal direction of the pouring part 200, and hot water is sprayed obliquely from the hole 2321 as shown in FIG. 11B.

  By rotating such a shower head 232 by the motor 221, the same effect as the nozzle head 231 described above can be obtained.

<Operation of the dispensing unit 200>
Next, operation | movement of the extraction part 200 when the user of the extraction apparatus 1 tries to brew coffee using the extraction part 200 is demonstrated.

  FIG. 12 is a diagram illustrating a control block of the extraction unit 200. As illustrated in FIG. 12, the control unit 240 of the dispensing unit 200 controls the motor 221 based on the operation information transmitted from the operation unit 206 and the on / off state of the hot water supply availability switch 207. Further, based on the operation information transmitted from operation unit 206, control unit 240 transmits hot water supply instruction information for requesting hot water transfer to control unit 130 of hot water storage unit 100.

  Hereinafter, the content of the operation input performed with respect to the operation part 206 and the operation | movement of the control part 240 are demonstrated concretely.

[Control for preheating the tube 300]
When the user preheats the tube 300 so that the hot water transferred from the hot water storage unit 100 does not cool before passing through the tube 300 before brewing coffee using the pouring unit 200, the operation unit 206 is used. The preheating instruction operation of the tube 300 is performed. Then, the operation unit 206 transmits information indicating that a preheating instruction has been made to the control unit 240. Receiving the information indicating that the preheating instruction has been made, the control unit 240 generates preheating instruction information for instructing preheating of the tube 300 and transmits it to the control unit 130 of the hot water storage unit 100. In response to this, the control unit 130 of the hot water storage unit 100 performs the control related to the preheating of the tube 300 described above, whereby the tube 300 is preheated.

  The hot water used for preheating the tube 300 may be discarded, for example, from the drain port 208 through the drain groove 209 or used for preheating the beverage container. When hot water is used for preheating the beverage container, the hot water in the beverage container may be discarded before the coffee is brewed by the user.

[Operation for supplying hot water from nozzle unit 210]
When the user brews coffee using the pouring unit 200, the user operates the operation unit 206 to specify the amount of hot water required for extraction. Specifically, for example, the operation unit 206 has operation buttons for designating the amount of hot water such as “large”, “medium”, and “small”, and the user can select the amount of coffee beans used or the size of the beverage container, for example. When the corresponding operation button is operated, the operation unit 206 transmits information indicating the requested amount of hot water to the control unit 240.

Receiving the information indicating the requested amount of hot water, control unit 240 generates hot water supply instruction information for instructing hot water storage unit 100 to supply hot water, and transmits it to control unit 130 of hot water storage unit 100. Accordingly, the control unit 130 of the hot water storage unit 100 performs the control related to the transfer of hot water described above,
Hot water is transferred from the hot water storage unit 100 to the pouring unit 200.

  The hot water transferred to the pouring part 200 through the tube 300 is transferred to the nozzle unit 210 via the hot water supply pipe 226. The transfer of hot water from the hot water storage unit 100 to the pouring unit 200 via the tube 300 and the transfer of hot water from the tube 300 via the hot water supply pipe 226 are performed by the pump 117 of the hot water storage unit 100.

  Moreover, the control part 240 will rotate the motor 221 by predetermined rotation, if operation which designates the quantity of hot water with respect to the operation part 206 is made by the user. By such control, the rotation of the motor 221 is transmitted to the nozzle unit 210 via the shaft 222, the pulley 223, the belt 224, and the pulley 225, and the nozzle head 231 rotates at a predetermined rotational speed. As a result, hot water is poured into the ground coffee beans prepared in advance by the user in the dripper 2051, and the coffee is extracted and stored in the beverage container.

  The rotational speed of the nozzle head 231 is determined based on an input to the operation unit 206 by the user of the dispensing device 1. Further, the rotation method of the nozzle head 231 may be set freely by the user operating the operation unit 206. The method for rotating the nozzle head 231 includes, for example, rotating the nozzle head 231 at a constant speed, changing the number of rotations according to time, or temporarily stopping the rotation.

  After the user operates the operation unit 206 to specify the amount of hot water required for extraction, the operation unit 206 is further operated so that the hot water is sprayed from the nozzle unit 210 in a plurality of times. May be. In this case, the user inputs the number of times that the hot water is divided and sprayed, the amount of each hot water, the interval at which the divided hot water is sprayed, the flow velocity, and the like via the operation unit 206, and the control unit 240 inputs the operation unit 206. The hot water supply instruction information is generated based on the information and transmitted to the control unit 130 of the hot water storage unit 100. Thereby, the hot water is sprayed from the nozzle unit 210 in a plurality of times.
