This corresponds to the power supply terminal of the battery mounting portion of the invention.

  The first power supply plus line 61 and the second power supply plus line 62 are provided with short-circuit prevention fuses Hs, respectively. As shown in FIG. 16, the short-circuit prevention fuse Hs is configured such that, for example, the plus terminal 42p and the minus terminal 42n of the second battery attachment portion 42 are connected to each other in a state where the first battery B1 of the first battery attachment portion 41 is attached. This is for cutting off the short-circuit current when it is accidentally short-circuited.

  The first power supply plus line 61 and the second power supply plus line 62 of the electric circuit 60 are provided with cover operation switches 64 that operate in conjunction with the front / rear slide operation of the cover member 45. That is, as shown in FIG. 16, when the cover member 45 covers the second battery mounting portion 42, the cover operation switch 64 blocks the second power supply plus line 62 between the second battery mounting portion 42 and the heater 54. Then, the first power supply plus line 61 between the first battery mounting portion 41 and the heater 54 is conducted. Further, as shown in FIG. 17, the cover operation switch 64 blocks the first power supply plus line 61 between the first battery mounting portion 41 and the heater 54 when the cover member 45 covers the first battery mounting portion 41. Then, the second power supply plus line 62 between the second battery mounting portion 42 and the heater 54 is conducted. The cover operation switch 64 is configured so that the first power supply plus line 61 and the second power supply plus line 62 can be shut off when the cover member 45 is removed from the battery mounting portion 40.

  As shown in FIGS. 16 and 17, the power source negative line 63 of the electric circuit 60 is provided with a switching element (FET) 65 for PWM control of the power supplied to the heater 54. The heater 54 is provided with a heater fuse Ht that blows when the temperature of the heater 54 rises too much. Furthermore, a temperature sensor 66 (for example, a thermistor) that detects the temperature of the pipe portion 52 is provided in the pipe portion 52 of the water heater 50.

  The electric circuit 60 includes a controller 70 that controls the heater 54 of the water heater 50 by operating the switching element (FET) 65. The controller 70 receives a signal from a start / stop switch 72 for turning on / off the heater 54 of the water heater 50. Here, the start / stop switch 72 is attached to the front surface of the plate portion 30 as shown in FIG. The energizing lamp is turned on while the heater 54 is operating. Further, a signal from the temperature sensor 66 is input to the controller 70. Further, the battery identification signal from the battery identification circuit 74 is input to the controller 70. The battery identification circuit 74 identifies the type of battery based on data transmitted from the battery B1 attached to the first battery attachment portion 41 or the battery B2 attached to the second battery attachment portion. Moreover, you may identify the kind of battery by grasping | ascertaining whether the battery is attached to which of the 1st battery attachment part 41 or the 2nd battery attachment part 42. FIG.

  The controller 70 is supplied with a plurality of types of constant voltages from the control power supply unit 75. That is, the control power supply unit 75 can supply a plurality of types of constant voltages to the controller 70 by stepping down or boosting the voltage supplied from the battery B1 (14.4V or 18V) or the battery B2 (10.8V). It is configured as follows.

<About the operation of the coffee maker 10>
When the coffee maker 10 is used, for example, when the battery for the electric tool is the first battery B1 (18V), the cover member 45 is slid to the rear end position as shown in FIG. (2) The first battery B1 is attached to the exposed first battery mounting portion 41 so as to cover the battery mounting portion 42. At this time, as the cover member 45 slides, the cover operation switch 64 operates, and as shown in FIG. 16, the second power supply plus line 62 is cut off and the first power supply plus line 61 becomes conductive. Next, the lid portion 23 on the upper surface of the housing 22 is rotated upward to open the opening of the water storage portion 22w and hold the lid portion 23 upright as shown in FIG. And in this state, water is inject | poured into the water storage part 22w. At this time, even if splashes of water fly, they are blocked by the lid portion 23 and are less likely to splash in the direction of the first battery B1. In this manner, the start / stop switch 72 is operated with the water injection completed, the coffee powder set in the drip case 21 and the decanter 35 set on the plate portion 30.

  When the start / stop switch 72 is operated, the controller 70 operates the switching element (FET) 65 in accordance with the type (voltage) of the battery, and adjusts the power supplied to the heater 54. For example, in the case of the first battery B1 (18V), the energization time in PWM control is shorter than that of the second battery B2 (10.8V). Then, the heater 54 heats the pipe portion 52 of the water heater 50, and the hot water in the pipe portion 52 is supplied to the cafe pod CP of the drip case 21. And the coffee extracted below by the extraction part 21p of the drip case 21 (case main-body part 21m) is stored in the decanter 35 on the plate part 30. FIG. In this way, when the water in the pipe portion 52 of the water heater 50 decreases and the temperature of the pipe portion 52 rises, the controller 70 receives the signal from the temperature sensor 66 and turns off the switching element (FET) 65. The energization of the heater 54 is stopped.

  When using the second battery B2 (10.8V), as shown in FIGS. 9 and 10, the cover member 45 is slid to the front end position to cover the first battery mounting portion 41 and exposed. The second battery B2 is attached to the battery mounting portion 42. Then, as the cover member 45 slides to the front end position, the cover operation switch 64 cuts off the first power supply plus line 61 and turns on the second power supply plus line 62 as shown in FIG. And coffee is extracted by operating the coffee maker 10 in the above-mentioned procedure.

<Advantages of the coffee maker 10 according to this embodiment>
According to the coffee maker 10 according to the present embodiment, the coffee maker 10 (electric equipment) can be operated at a construction work site or the like using the batteries B1 and B2 of the electric tools. The coffee maker 10 includes a drip case 21 (case part) in which a cafe pod CP (pod product) in which a predetermined amount of coffee powder is stored in a water-permeable bag-like member is set. The drip case 21 is provided with an extraction unit 21p for extracting coffee generated by hot water poured into the set cafe pod CP. Thus, since the cafe pod CP can be used, for example, the work of taking out the coffee powder from the bag of coffee powder with a measuring spoon or the like and setting it on the filter becomes unnecessary. That is, if the coffee maker 10 is operated by setting the cafe pod CP in the drip case 21, the coffee can be obtained, so that the coffee can be easily provided at the construction work site.

  Further, since the water storage part 22w and the drip case 21 (case part) of the coffee maker 10 are arranged at substantially the same height, the hot water supply part 50y drips the hot water boiled by the heater 54 (heating means). When supplying the case 21 from above, water supply means such as a pump becomes unnecessary. Further, the battery mounting portions 41 and 42 are provided at positions lower than the water storage portion 22 w and the drip case 21. For this reason, when boiling water, the heavy batteries B1 and B2 are arranged at low positions, and the stability of the coffee maker 10 is improved. Furthermore, since the water storage space W and the hot water space Y in which the heater 54 is stored are partitioned by the upper and lower partition walls 210, there is no problem that water enters the space Y in which the heater 54 is stored. Further, since the nozzle storage space N in which the hot water supply nozzle portion 57 of the hot water supply portion is stored and the water heater space Y in which the heater 54 is stored are partitioned by the vertical wall 212, there is a problem that hot water enters the water heater space Y. Does not occur.

  According to the coffee maker 10 according to the present embodiment, in a state where the corresponding batteries B1 and B2 are attached to any one of the battery attachment portions 41 and 42, the other battery attachment portions 41 and 42 are Corresponding batteries B1 and B2 cannot be attached. For this reason, even if two types of battery mounting portions 41, 42 are provided, only one battery B1, B2 can be mounted on the battery mounting portions 41, 42. That is, two batteries are not attached to the battery attachment portions 41 and 42 at the same time. This eliminates the need for a battery switching circuit, an interlock circuit, and the like, simplifying the circuit configuration and improving the electrical reliability.

  Further, with the batteries B1 and B2 attached to one exposed battery attachment portion 41 and 42, the other battery attachment portions 41 and 42 are covered with the cover member 45. That is, in the state where the batteries B1 and B2 are attached to one battery attachment portion 41 and 42, the charging portion of the other battery attachment portions 41 and 42 is not exposed, so that a short circuit accident can be prevented. Further, when the batteries B1 and B2 are attached to one battery attachment portion 41 and 42, another battery B1 and B2 are moved in the attachment direction (downward) with respect to the other battery attachment portions 41 and 42. The other batteries B1 and B2 are in contact with the batteries B1 and B2 attached to one battery attachment portion 41 and 42, and the movement of the other batteries B1 and B2 is stopped. For this reason, even if the cover member 45 is removed, there is no problem that the plurality of batteries B1, B2 are attached to the plurality of battery attachment portions 41, 42.

  Further, the lid portion 23 of the water storage portion 22w rises like a bowl at the edge of the upper surface of the housing 22 that is located above the right side surface of the housing 22 where the battery mounting portions 41 and 42 are provided. The opening of the portion 22w is configured to be opened. For this reason, when supplying water to the water storage part 22w of the housing 22, the splash of water is obstructed by the lid part 23 standing along the right side surface of the housing 22 and is difficult to be applied to the battery mounting parts 41 and 42. .

<Example of change>
In addition, this invention is not limited to the said embodiment, The change in the range which does not deviate from the summary of this invention is possible. For example, in the coffee maker 10 of the present embodiment, as shown in FIGS. 1 and 13, the water storage part 22w and the drip case 21 (case part) are arranged side by side at substantially the same height, and the position is lower than that. An example in which the battery mounting portions 41 and 42 are provided is shown. However, as shown in FIG. 20, it is also possible to provide the battery attachment parts 41 and 42 at a position higher than the water storage part 22w and the drip case 21 (case part). Moreover, as shown in FIG. 21, it is also possible to provide the water storage part 22w in the position lower than the heater 54 of the water heater 50, and to provide the battery attachment parts 41 and 42 in a position higher than the water storage part 22w. is there. In this case, a pump 59 or the like is used for pumping water. Thus, when battery attachment parts 41 and 42 are arranged in a position higher than water storage part 22w, when supplying water to water storage part 22w, it becomes difficult to splash water on battery attachment parts 41 and 42.

  Moreover, in the coffee maker 10 of this embodiment, as shown to the electric circuit 60 of FIG. 16, FIG. 17, when using 1st battery B1 (18V) and using 2nd battery B2 (10.8V) In the above example, the common heater 54 is used. However, as shown in FIG. 18, when the first battery B1 (18V) is used, the dedicated A heater 54a and the FET 65a are used, and when the second battery B2 (10.8V) is used, the dedicated B A configuration using the heater 54b and the FET 65b is also possible. Further, as shown in FIG. 19, when the first battery B1 (18V) is used, the A heater 54a, the B heater 54b, the FET 65a, the FET 65b are used, and the second battery B2 (10.8V) is used. It is also possible to adopt a configuration using the B heater 54b and the FET 65b.

  Further, in the present embodiment, the contact type switch is exemplified as the cover operation switch 64 that operates in conjunction with the back-and-forth slide operation of the cover member 45, but a semiconductor type switch can also be used. Moreover, in this embodiment, the coffee maker 10 provided with the 1st battery attachment part 41 and the 2nd battery attachment part 42 from which size differs corresponding to 1st battery B1 and 2nd battery B2 was illustrated. However, for example, the sizes of the first battery mounting portion 41 and the second battery mounting portion 42 can be made equal to correspond to the first battery B1 (18V, 14.4V). Further, in the coffee maker 10 according to the present embodiment, the heat retaining function of the plate 30 on which the decanter 35 is placed is not considered, but the plate 30 can be provided with a heat retaining function. In this case, in the electric circuit 60 shown in FIG. 16 and the like, it is preferable to provide a heat retaining heater for the plate 30 in parallel with the heater 54 and the switching element 65 of the water heater 50.

  In the present embodiment, the case main body 21m of the drip case 21 is for the coffee pod CP shown in FIGS. 5 and 6, and for the coffee powder using the mesh filter F shown in FIGS. An example in which and are provided separately is shown. However, as shown in FIGS. 22 to 25, it is also possible to use both the case body 21m for the cafe pod CP and the case body 21m for the coffee powder using the mesh filter F. In the present embodiment, the coffee maker 10 is exemplified as the electric device. However, the present invention can be applied to a tea machine using a tea leaf body product.
