In FIG. 2, the right direction along the plane of the page is the X direction (front), the left direction is the -X direction (rear), the front side of the page is the Y direction (left direction), and the depth direction of the page is the -Y direction (right direction). . Also, the lower side of a certain member or surface is the lower side, the upper side is the upper side, the front side is the front side, the rear side is the rear side, the left side is the left side, and the right side is the right side That's it.

  As shown in FIGS. 1 and 2, the coffee maker E has a hot water supply unit 1, a mill unit 2, an extraction unit 3, a container 4, a placement unit 5, an operation unit 6, and a housing 7 (support unit). ) And a control unit M. A placing part 5 on a flat plate is formed at the lower end of the coffee maker E, and a casing 7 as a supporting part is in contact with the outside of the placing part 5, that is, the rear side, the left side, and the right side in a top view. It is erected. The housing 7 is a box-shaped member surrounded by the front surface 7a, the back surface 7b, the top surface 7c, the right front surface 7d, and the bottom surface 7e, and supports the mill unit 2 and the extraction unit 3 above the placement unit 5. ing.

  As shown in FIG. 1, the extraction unit 3 is arranged on the upper side of the placement unit 5 and supported by the housing 7. As shown in FIG. 2, the mill unit 2 is arranged on the upper side of the extraction unit 3 and supported by the housing 7. The operation unit 6 is disposed on the right front surface 7 d of the housing 7, and the hot water supply unit 1 and the control unit M are disposed inside the housing 7. A tank 10 for storing water is disposed on the rear side of the upper portion of the housing 7. And at the time of extraction of coffee C (beverage), the container 4 is placed on the upper side of the placing part 5 and is arranged below the extracting part 3. In FIGS. 1 and 2, an attached server 40 that is an accessory of the coffee maker E is shown as the container 4.

  As shown in FIG. 2, the hot water supply unit 1 includes a tank 10, a hot water supply pipe 11, a heater 12, and a nozzle 13. The hot water supply pipe 11 is connected to the lower part of the tank 10 inside the casing 7, is bent in a U shape at the lower part of the casing 7, and extends to the uppermost part of the casing 7. The hot water supply pipe 11 again extends to the lower part of the casing 7 and curves in a U shape, and then extends to the uppermost part of the casing 7 again and is connected to the nozzle 13.

  In the hot water supply unit 1, the curved portion of the hot water supply pipe 11 described above is disposed so as to overlap, and the heater 12 is disposed so as to cover the curved portion. The hot water supply unit 1 generates heat when the heater 12 is energized, and heats the water inside the hot water supply pipe 11. In the hot water supply unit 1, hot water is sent to the nozzle 13 due to an increase in pressure of water (hot water) in the hot water supply pipe 11 due to heating, and is supplied to the extraction unit 3 through the inside of the mill unit 2. When the water in the tank 10 and the hot water supply pipe 11 runs out, the temperature of the heater 12 rises. When the control unit M detects the temperature rise, the control unit M stops energizing the heater 12.

  The mill unit 2 includes a mill case 20, a mill blade 21, and a motor 22. The mill case 20 has a passage 20c that communicates from the upper inlet 20a to the lower outlet 20b. A mill blade 21 that is rotationally driven by a motor 22 is disposed in the middle of the passage 20c.

  The lid 14 at the top of the housing 7 can be rotated upward about the rotation axis C1, and coffee beans are introduced from the exposed inlet 20a. The coffee beans charged in the mill case 20 are pulverized by the rotating mill blade 21 to be powdered and supplied to the extraction unit 3 through the outlet 20b. When coffee C is extracted, hot water supplied from the nozzle 13 flows from the inlet 20a to the passage 20c and is supplied from the outlet 20b to the extraction unit 3.

  The extraction unit 3 includes a holder 30 and a dripper 31, and the dripper 31 is placed on the holder 30. The holder 30 is supported by the housing 7 in a rotatable state by a right pin 30a (FIG. 1). With the holder 30 rotated and opened in the right direction, the dripper 31 is attached and detached, and the filter is attached to the dripper 31, and the coffee C is extracted when the holder 30 is rotated in the left direction and closed (FIG. 1). Do. The dripper 31 has an inlet 31 a provided in the lid 38, an extraction port 31 b provided in the lower part of the dripper 31, and an extraction space 31 c surrounded by the dripper 31 and the lid 38. In the extraction unit 3, the coffee beans crushed by the mill unit 2 are supplied from the inlet 31a to the extraction space 31c. Thereafter, the extraction unit 3 supplies the hot water supplied from the hot water supply unit 1 to the extraction space 31c from the inlet 31a, extracts the coffee C from the coffee beans using the hot water, and supplies the extracted coffee C to the container 4 described later in detail.

  A dripper valve 32 is inserted into the extraction port 31b of the dripper 31 and is urged downward by a spring 32a. The lever 33 is attached to the dripper 31 in a state where the lever 33 can swing around the rotation axis C <b> 3, and the front end of the lever 33 is connected to the dripper valve 32. A cam 35 is disposed at a position behind the lever 33 in the housing 7.

  The rotation of the motor 34 causes the cam 35 to take two states: a separated state in which the cam 35 is separated from the lever 33, and a depressed state in which the rear end of the lever 33 is pushed down. In the separated state, the dripper valve 32 is pushed downward by the spring 32a, and the O-ring 32b blocks the extraction port 31b, so that the coffee C does not flow out of the extraction port 31b. In the pressed state, the dripper valve 32 is pushed up by the lever 33, and the coffee C flows out from the gap between the dripper valve 32 and the extraction port 31b. The coffee C that has flowed out of the dripper 31 is accommodated in the attached server 40 arranged below the extraction unit 3.

  The container 4 accommodates the coffee C supplied from the extraction unit 3, and various forms such as the attached server 40 shown in FIGS. 1 and 2 and the cup 41 shown in FIG. 5 can be used. . The attached server 40 is a metal insulated double structure container, and includes a lever 40a, a valve member 40b, and a spout 40c. The valve member 40b is urged upward by a spring (not shown).

  In a state where the attached server 40 is not attached to the coffee maker E (FIG. 1), the valve member 40b closes the inlet 40d at the upper part of the attached server 40. When the attached server 40 is attached to the coffee maker E, that is, when the attached server 40 is placed on the upper side of the mounting portion 5 (FIG. 2), the rib 36 formed on the lower side of the dripper 31 pushes down the valve member 40b. Thus, the inlet 40d is opened. In this state, when the dripper valve 32 of the dripper 31 is moved upward by the operation of the motor 34, the coffee C flows out from the extraction port 31b along the surface of the dripper valve 32 and falls downward. And the fallen coffee C is accommodated in the inside of the attached server 40 through the upper opening part (not shown) and the inflow port 40d of the valve member 40b.

  Hereinafter, the structure of the mounting portion 5 and spill detection, which are characteristic configurations of the coffee maker E according to the present embodiment, will be described.

  As shown in FIG. 3, the placement unit 5 includes a first beverage receiving member 51 and a second beverage receiving member 52, and these are arranged in a recess 50 provided in the placement unit 5. The first beverage receiving member 51 is a metal member, has a first bottom surface portion 51 a and a first side wall portion 51 b, and can receive a spilled beverage that does not fit in the container 4. . The 1st side wall part 51b is standingly arranged in the circumference | surroundings of the 1st bottom face part 51a, and the 1st drink receiving member 51 becomes a dish shape with the depth as a whole. In the present embodiment, the first beverage receiving member 51 is fitted and fixed in the recess 50.

  The second beverage receiving member 52 is a resin member and has a second bottom surface portion 52a, a second side wall portion 52b, and a rib 52c. The 2nd side wall part 52b is standingly arranged in the circumference | surroundings of the 2nd bottom face part 52a, and the 2nd drink receiving member 52 becomes the dish shape with the depth as a whole. A resin net 53 is placed on the upper side of the second beverage receiving member 52.

  As shown in FIG. 4, the temperature measurement unit 54 is disposed outside the first beverage receiving member 51 in a state of being in contact with the first side wall 51 b of the first beverage receiving member 51. The temperature measurement part 54 measures the temperature of the 1st drink receiving member 51, especially the temperature of the 1st side wall part 51b.

  In this embodiment, the temperature measurement part 54 is arrange | positioned in contact with the 1st site | part 51c which is a site | part nearest to the front direction (X direction) in the 1st side wall part 51b. Here, in the coffee maker E, as shown in FIG. 4, the first beverage receiver is seen in a top view (viewed in the −Z direction) while the casing 7 is in contact with the rear side (−X direction) of the placement portion 5. It is erected outside the member 51. The front surface 7 a of the housing 7 is erected in a state of surrounding the rear half of the first beverage receiving member 51.

  That is, the 2nd site | part 51d shown by the arrow A among the 1st side wall parts 51b of the 1st drink receiving member 51 is a site | part which faces the housing | casing 7 (support part). And among the 1st side wall parts 51b, the 3rd site | part 51e shown by the arrow B is a site | part which does not face the housing | casing 7 (support part). That is, the temperature measurement part 54 is arrange | positioned in contact with the 3rd site | part 51e which does not face the housing | casing 7 (support part) in the said 1st side wall part 51b of the 1st drink receiving member 51. FIG.

  The arrangement of the temperature measuring unit 54 in the first part 51c or the third part 51e has the following advantages. The coffee maker E is usually installed in a kitchen or a table, but may be installed at an angle. For example, when the coffee maker E is installed to be inclined rearward, the coffee C that has spilled out of the container 4 flows backward (−X direction). In this case, since the housing 7 (supporting portion) is erected in the −X direction as viewed from the first beverage receiving member 51, the outflow of the coffee C from the coffee maker E is blocked and suppressed by the housing 7. . The same applies when the coffee maker E is disposed obliquely in the rearward direction.

  On the other hand, when the coffee maker E is disposed to be inclined forward (or obliquely forward), the spilled coffee C flows forward or obliquely forward. In this case, since the housing 7 (supporting portion) does not exist in the X direction when viewed from the first beverage receiving member 51, the outflow of the coffee C from the coffee maker E cannot be suppressed. Therefore, in this case, it is required to detect the spillage of the coffee C as soon as possible and stop the discharge of the coffee C from the extraction unit 3.

  In the coffee maker E, the temperature measuring unit 54 is disposed in the first part 51c or the third part 51e. For this reason, when coffee C flows in the forward direction or the oblique direction, that is, in the direction in which the support portion (housing 7) is not erected, the detection of spillage of coffee C to the first beverage receiving member 51 is quickly performed. Can do. Therefore, disposing the temperature measuring unit 54 in contact with the portion of the first side wall 51b of the first beverage receiving member 51 that does not face the support (housing 7) enhances the use comfort of the coffee maker E. Preferred above.

  As is clear from FIG. 1, when the container 4 is taken in and out of the coffee maker E, that is, when the container 4 is placed on the placement part 5 from the outside of the coffee maker E, or the container 4 is lowered from the placement part 5. In this case, the container 4 passes through a space where the support portion (housing 7) does not exist. Therefore, the same effect can be obtained by arranging the temperature measuring unit 54 below the passage region when the container 4 is attached and detached.

  Next, spill detection will be described with reference to FIG. In the example shown in FIG. 5, a cup 41 is used as the container 4, and the cup 41 is placed on the net 53 of the placement unit 5. Coffee C is supplied to the cup 41 from the extraction unit 3 disposed on the upper side of the placement unit 5. In the state shown in FIG. 5A, the coffee C is accommodated in the cup 41, and no spillage of the coffee C from the cup 41 occurs.

  The second beverage receiving member 52 is formed to be slightly smaller than the first beverage receiving member 51. When the second beverage receiving member 52 is placed on the upper side of the first beverage receiving member 51, the second beverage receiving member 52 is formed by the ribs 52c (FIG. 3) formed around the second beverage receiving member 52. One beverage receiving member 51 is arranged near the center. A first beverage storage space S <b> 1 is formed between the second side wall portion 52 b of the second beverage receiving member 52 and the first side wall portion 51 b of the first beverage receiving member 51. In this embodiment, the 1st drink storage space S1 is the form which surrounds the circumference | surroundings of the 2nd drink receiving member 52, and is formed in the annular | circular shape by the top view. Moreover, the 2nd drink receiving member 52 has 2nd drink storage space S2 enclosed by the 2nd bottom face part 52a and the 2nd side wall part 52b. The second beverage storage space S2 has a circular shape when viewed from above.

  When coffee C is further poured into the cup 41 from the state shown in FIG. 5A, the cup 41 is filled with the coffee C, and the coffee C spills out from the cup 41 (FIG. 5B). The spilled coffee C passes through the gap provided in the net 53 and is poured into the second beverage storage space S2 of the second beverage receiving member 52, where it is stored.

  When coffee C is further poured into the cup 41 from the state shown in FIG. 5B, the second beverage storage space S2 is filled with the coffee C overflowing from the cup 41, and the coffee C overflows from the second beverage storage space S2. put out. The overflowing coffee C is poured from the periphery of the second beverage receiving member 52 into the first beverage storage space S1, and stored in the first beverage storage space S1 as shown in FIG. 5 (c). In addition, since the rim 51g is provided in the upper end of the 1st side wall part 51b of the 1st drink receiving member 51, and the circumference | surroundings of the rim 51g are sealed watertight (FIG. 2), the spilled coffee C is a mounting part. 5 and the inside of the housing 7 are prevented from entering.

  Since the coffee C is at a high temperature immediately after extraction, the first side wall 51b comes into contact with the first side wall 51b of the first beverage receiving member 51 and the coffee C stored in the first beverage storage space S1. Temperature rises.

  The control part M acquires and records the output of the temperature measurement part 54 arrange | positioned in contact with the 1st side wall part 51b every second. And the control part M compares the present temperature with the temperature of 1 minute ago, for example, and when the present temperature is 3 degreeC or more larger than the temperature of 1 minute ago, it is coffee C to the 1st drink receiving member 51. Judge that a spill occurred.

  When the control unit M determines that the coffee C spills into the first beverage receiving member 51, the control unit M stops energization of the heater 12 that heats the water from the tank 10, and ends the extraction of the coffee C. That is, when the control unit M detects that coffee C has been spilled on the first beverage receiving member 51 based on the output of the temperature measurement unit 54, the control unit M stops the supply of hot water from the hot water supply unit 1 to the extraction unit 3.

  Here, the advantage of 1st drink storage space S1 is demonstrated. Consider a case where the second beverage receiving member 52 is not placed on the upper side of the first beverage receiving member 51 and the first beverage storage space S1 is not formed. In this case, since the coffee C that has flowed into the first beverage receiving member 51 spreads thinly over the entire first bottom surface portion 51a, the rising speed of the water level of the coffee C that accumulates in the first beverage receiving member 51 is slow. If it does so, since the speed of the area increase of the area | region where the 1st side wall part 51b and the coffee C contact will also become slow, the temperature rise of the 1st side wall part 51b by the coffee C will also reduce the speed. As a result, spill detection by the control unit M is also delayed.

  When the second beverage receiving member 52 is placed on the upper side of the first beverage receiving member 51 and the first beverage storage space S1 is formed, the coffee C flowing into the first beverage receiving member 51 is the first beverage storage space. Stored in S1. Here, since the bottom area of the first beverage storage space S1 is smaller than the bottom area of the first beverage receiving member 51, the rising speed of the water level of the coffee C is compared with the case where the second beverage receiving member 52 is not placed. Become bigger. That is, by forming the first beverage storage space S1 by the first beverage receiving member 51 and the second beverage receiving member 52, even if the same amount of coffee C is spilled, the rising speed of the water level is increased. The speed of the temperature rise of the 1 side wall part 51b can be raised, and the spilling detection of the drink to the 1st drink receiving member 51 can be performed more rapidly.

  In the above description, the coffee C overflowing from the cup 41 has been described on the assumption that it flows into the first beverage storage space S1 after filling the second beverage storage space S2. However, when a container having a larger outer diameter than the cup 41 (for example, a cup larger than the second beverage receiving member 52 in a top view) is used, or when the coffee C overflows using the attached server 40 (for example, attached) For example, when the server 40 is shifted from the correct position), the coffee C may flow directly from the container 4 or the extraction unit 3 into the first beverage storage space S1. Even in such a case, spillage can be appropriately detected by the first beverage storage space S1 and the temperature measurement unit 54.

  With reference to the flowchart shown in FIG. 6, the extraction operation performed in the coffee maker E will be described. First, a paper filter is arranged in the dripper 31 of the extraction unit 3 by the user, water is supplied to the tank 10, coffee beans are introduced from the inlet 20 a of the mill case 20, and the container 4 is placed on the upper side of the placement unit 5. . And if a user operates the operation part 6 and instruct | indicates the extraction of coffee C, extraction operation will be started.

  In step # 01 (mill operation), the control unit M operates the motor 22 of the mill unit 2 to rotate the mill blade 21 to pulverize the coffee beans that have been charged. The coffee beans that have been pulverized into powder are supplied from the outlet 20 b to the extraction unit 3 through the inlet 31 a and fall onto a paper filter disposed in the dripper 31. After a preset time has elapsed, the control unit M stops the motor 22, ends step # 01, and proceeds to step # 02.

  In step # 02 (start of hot water supply), the control unit M starts energization of the heater 12 of the hot water supply unit 1 to heat the water inside the hot water supply pipe 11. The heated hot water flows out from the nozzle 13, passes through the passage 20 c of the mill case 20, and is supplied to the extraction unit 3. While continuing energization of the heater 12, the process proceeds to the subsequent step # 03.

  In step # 03 (extraction start), the control unit M operates the motor 34 of the extraction unit 3 to open the dripper valve 32. Then, coffee C flows out from the extraction port 31 b of the dripper 31, and the coffee C is stored in the container 4. The dripper valve 32 is opened when a predetermined time elapses from an extraction instruction (operation of the operation unit 6) by the user.

  In Step # 04, the control unit M determines whether or not the coffee C has been spilled on the first beverage receiving member 51. Specifically, the control unit M acquires the output of the temperature measurement unit 54 and compares it with the stored temperature of the first beverage receiving member 51 one minute before. When the current temperature is 3 ° C. or more higher than the temperature one minute ago, it is determined that coffee C has spilled into the first beverage receiving member 51 (Yes), and hot water is supplied to the extraction unit 3 (Extraction operation ends). Specifically, the control unit M stops the energization of the heater 12 and stops the heating of the hot water supply pipe 11. Otherwise, it is determined that no spill has occurred (No), and the process proceeds to step # 05.

  In step # 05, the control unit M determines whether or not the water stored in the tank 10 is exhausted. Specifically, the control unit M acquires the temperature of the heater 12 from a temperature sensor (not shown) and compares it with a stored threshold value. If the current temperature of the heater 12 is smaller than the threshold value, it is determined that there is no water (No), and the process returns to step # 04.
