In addition, by adopting the induction heating method, the time for boiling water is shortened, and as a result, milk can be prepared in a short time. Instead of the induction heating method, a resistance heating method using a resistance heating element can be employed as the heater 3.

  The heat sink 4 is a cooling means for cooling the water heated by the heater 3, and is disposed below the water container 2 and the heater 3. The heat sink 4 is made of, for example, a metal material having good heat conductivity such as aluminum, and a concave water channel 30 through which water heated by the heater 3 flows is formed on the heat sink 4.

  The water channel 30 has a concave shape that opens upward, and has a bottom surface that is inclined so that water flows down due to gravity. In the vicinity of the deepest part of the water channel 30, an outflow hole 37 penetrating from the water channel 30 to the lower surface of the heat sink 4 is formed. Specifically, the bottom surface of the water channel 30 is inclined so as to descend toward the front, and the outflow hole 37 is formed above a portion protruding forward of the housing 10, that is, a position where the baby bottle 40 is placed. Has been.

  A through hole 38 is formed in the partition member of the housing 10 located below the heat sink 4 at a position corresponding to the outflow hole 37. Thus, the water that has flowed through the water channel 30 of the heat sink 4 and cooled to a predetermined temperature passes through the outflow hole 37 and the through hole 38 and is dropped downward.

You may make it form a flow path (through-hole) automatically.

  The milk preparation apparatus 1 having the above-described configuration prepares milk by dropping water heated to a high temperature by the heater 3 by the heat sink 4 and then dripped into the capsule 9. As a result, water is sterilized by heating to, for example, 70 ° C. or higher with the heater 3 and then rapidly cooled with the heat sink 4 to efficiently prepare milk or the like at a temperature suitable for sucking (for example, around 40 ° C.). can do.

  Moreover, the milk preparation apparatus 1 has a blower 7 that sends cooling air to the heat sink 4. Specifically, as the blower 7, for example, an axial-flow type propeller fan and a motor are used to supply air to portions other than the water channel 30 of the heat sink 4, that is, the lower surface and side surfaces. Since air can be sent to the heat sink 4 by the blower 7 and the heat sink 4 can be cooled by heat exchange with the air, the cooling efficiency of water in the heat sink 4 can be improved.

  In addition, a suction port (not shown) for introducing air into the housing 10 from the outside and an exhaust port (not shown) for discharging air from the inside of the housing 10 are provided. The suction port and the exhaust port You may arrange the air blower 7 and the heat sink 4 in the air path which connects. Thereby, air can be taken in from the outside of the housing 10 to cool the heat sink 4, and heat that is heated by the heat sink 4 to be heated can be discharged to the outside of the housing 10.

  In addition, the cooling effect can be obtained only by the cooling by the blower 7, but a cooler 5 may be provided to cool the heat sink 4 more efficiently. As the cooler 5, for example, a Peltier type refrigerator or the like can be employed. The air cooled by the cooler 5 is sent to the heat sink 4 by the blower 7.

  When the cooler 5 is provided, an air path (not shown) for circulating cooling air is provided inside the housing 10, and the air supplied to the heat sink 4 by the blower 7 is circulated inside the housing 10. Also good.

  Further, instead of the configuration in which the heat sink 4 is indirectly cooled by using air as a heat transfer medium as described above, the cooling side of the cooler 5 is brought into contact with the heat sink 4 so that the heat sink 4 can be directly connected by heat conduction between solids. It is also possible to employ a cooling structure.

  By providing the cooler 5 in this way, the heat sink 4 can be further efficiently cooled, and the water heated by the heater 3 can be efficiently and rapidly cooled by the heat sink 4.

  The cooler 5 is provided with a heat dissipating blower 8 for cooling the heat dissipating side of the cooler 5. The blower 8 is, for example, an axial flow type propeller fan and a motor. The housing 10 is formed with a suction port (not shown) for introducing heat radiation air from the outside, and a heat radiation exhaust port (not shown) for discharging air from the inside of the housing 10. In addition, the blower 8 is disposed in an air path that connects the suction port and the exhaust port for heat dissipation. Thereby, air can be taken in from the exterior of the housing | casing 10, the heat radiation side of the cooler 5 can be cooled, the exhaust heat of the cooler 5 can be discharged | emitted outside the housing | casing 10, and the cooling efficiency of the cooler 5 is improved. be able to.

In addition, the milk preparation apparatus 1 may include, for example, a temperature sensor, a current sensor, a pressure sensor, and other various sensors (not shown) for detecting an operation state such as the temperature of each part.

  FIG. 3 is an exploded perspective view of the milk preparation device 1. As shown in FIG. 3, the water container 2 includes a substantially bottomed cylindrical container body 21 and an outer tube 24, a sealing member 25, a seal member 26, and a lid body 22 that are attached to the container body 21 so as to be disassembled and assembled. Have. The container body 21 is integrally formed with a substantially cylindrical inner tube 23 that forms a flow path penetrating from the inside to the outside on the bottom surface of the container body 21.

  A substantially cylindrical outer tube 24 is fitted on the outside of the inner tube 23 with a predetermined gap serving as a water flow path. Are fitted. Thereby, the siphon part 20 is comprised. Details will be described later with reference to FIGS. 5 and 6.

  A substantially disc-shaped lid 22 that closes the opening is attached to the upper opening of the container body 21 through a seal member 26 in a sealed state. The integrally assembled water container 2 is detachably mounted on a concave water container mounting portion 11 formed on the upper portion of the housing 10 and is locked by a lock mechanism 27. In addition, a through hole 35 communicating with a heat sink mounting portion 13 described later is formed at the bottom of the water container mounting portion 11.

  As described above, the water container 2 is detachably attached to the housing 10 and is configured such that each component can be disassembled. Thereby, the user can remove and decompose | disassemble the water container 2 after use, and can clean easily.

  A heat sink mounting portion 13 that opens to the front surface is formed below the water container mounting portion 11 of the housing 10. The heat sink 4 has a lid 31 and a heat sink cover 15 attached thereto, and is detachably attached to the heat sink attachment portion 13.

  A capsule holder mounting portion 14 that opens to the front surface is formed in the housing 10 below the heat sink mounting portion 13. A capsule holder 16 is detachably mounted on the capsule holder mounting portion 14. Thereby, the capsule holder 16 can be removed and cleaned.

  In addition, the through-hole 38 (refer FIG. 2) is formed in the partition member between the heat sink mounting part 13 and the capsule holder mounting part 14 as mentioned above. A through hole 39 is formed in the lower surface of the capsule holder mounting portion 14.

  The pedestal 19 for placing the baby bottle 40A having a low height, that is, a small capacity, is detachably attached to the lower front portion of the housing 10. For example, the magnetic force of a magnet can be used for fixing the housing 10 and the pedestal 19. Thereby, the base 19 can be attached and detached easily.

  By providing the detachable pedestal 19, it is possible to use a plurality of types of baby bottles 40 having different capacities (for example, a baby bottle 40A having a small capacity and a baby bottle 40B having a large capacity) according to the growth of the infant.

  FIG. 4 is a perspective view of the heat sink 4 and the lid 31 and the heat sink cover 15 assembled thereto. As shown in FIG. 4, the water channel 30 formed in the upper part of the heat sink 4 has a groove shape that is open at the top and recessed downward.

  A substantially plate-shaped lid 31 is detachably attached to the upper portion of the heat sink 4 so as to close the water channel 30 from above. Thereby, the cover 31 can be removed and the concave water channel 30 and the cover 31 can be easily washed. That is, the water channel 30 through which water flows can be cleaned to suppress the propagation of germs and the like, and can be kept hygienic.

  The lid 31 is formed with a through-hole 36 that allows passage of water dripped from the water container 2 (see FIG. 2). Further, a sealing member (not shown) surrounding the peripheral edge of the water channel 30 may be interposed between the lid 31 and the heat sink 4. Thereby, the airtightness of the water channel 30 can be maintained, and the leakage of water etc. can be suppressed.

  Radiation fins 32 are formed in the water channel 30. Thus, the water heated by the heater 3 (see FIG. 2) can be efficiently and rapidly cooled by the heat sink 4. That is, heat exchange between water and the heat sink 4 can be promoted by providing the radiation fins 32 in the water channel 30 through which the water heated by the heater 3 flows.

  As a form of the radiation fin 32, for example, various fin shapes such as a rod shape, a needle shape, and a plate shape protruding from the bottom surface of the water channel 30 in a staggered arrangement can be adopted. The radiating fin 32 may have any shape as long as it increases the heat transfer area of the water channel 30 and disturbs the flow of water to promote heat transfer. For example, by reducing the height of the radiating fin 32, The bottom surface of the water channel 30 may be formed in an uneven shape such as a wave shape. In addition, as the radiating fins 32, a large number of dimples may be formed on the bottom surface.

  Further, the bottom surface of the water channel 30 may be flat (inclined plane) without forming the heat radiation fins 32 in the water channel 30. By forming the bottom surface of the water channel 30 flat, there is an advantage that the water channel 30 can be easily cleaned.

  Further, the substantially fin-shaped heat radiation fins 32 extending in the left-right direction may be alternately formed on the left and right sides so that the water flowing from the through holes 36 flows in a meandering manner toward the outflow holes 37. Alternatively, the recess that becomes the water channel 30 may be formed in a meandering shape. Thereby, the path | route which the water flows in the heat sink 4 can be lengthened, and water can be cooled efficiently.

  On the lower surface of the heat sink 4, for example, substantially plate-shaped heat radiation fins 33 are formed. Thus, by forming the radiation fins 33 other than the water passage 30 such as the lower surface of the heat sink, heat radiation from the heat sink 4 to the outside can be promoted. In addition, the radiation fin 33 is not limited to a substantially plate shape, and various fin shapes can be adopted.

  A heat sink cover 15 is detachably fitted to the front end portion of the heat sink 4. And as above-mentioned, since the heat sink 4 is attached to the housing | casing 10 (refer FIG. 3) detachably, the heat sink 4 can be removed from the milk preparation apparatus 1, and it can wash | clean easily.

  FIG. 5 is a side cross-sectional view (part A detail view shown in FIG. 2) showing the vicinity of the siphon part 20 of the milk preparation apparatus 1. As shown in FIG. 5, the inner tube 23 formed integrally with the container main body 21 of the water container 2 has a substantially cylindrical shape and penetrates the bottom surface of the container main body 21 so as to protrude inward and outward. It is formed. Thereby, the flow path in which water flows from the water container 2 to the heat sink 4 disposed below the water container 2 is formed.

  A portion of the inner tube 23 that protrudes downward from the lower surface of the container body 21 is inserted into a through hole 35 that allows the water container mounting portion 11 and the heat sink mounting portion 13 to communicate with each other. Thereby, the water in the water container 2 can be dripped in the vicinity of the through-hole 36 of the lid 31 and guided to the water channel 30 of the heat sink 4 while suppressing scattering to the surroundings.

  An outer tube 24 is detachably mounted on the outer peripheral side of the inner tube 23 projecting from the water container 2 while ensuring a gap for water to flow. And the upper end part of the outer tube | pipe 24 is sealed by the sealing member 25 fitted so that attachment or detachment is possible. On the other hand, the lower end portion of the outer tube 24 is separated from the bottom surface of the container main body 21 so as to ensure a gap through which water flows.

  With the above configuration, the releasable siphon part 20 that guides the water in the water container 2 to the water channel 30 of the heat sink 4 is formed. That is, the water in the water container 2 is heated by the heater 3 to pass through the gap between the lower end portion of the outer tube 24 and the bottom surface of the container body 21, and the gap between the outer tube 24 and the inner tube 23, The gas passes through the gap between the upper end of the inner tube 23 and the sealing member 25 and the inside of the inner tube 23 in sequence, and flows from the through hole 36 of the lid 31 to the water channel 30 of the heat sink 4.

  In this way, by forming the siphon portion 20, no means for sending water such as a pump is required, and the water in the water-soluble device 2 is drained from the water container 2 to the water channel 30 of the heat sink 4 without power from the outside. Can be shed. Note that substantially all the water in the water container 2 can be sent out to the water channel 30 by the siphon unit 20 having the above-described configuration.

  Thus, since the milk preparation apparatus 1 provided with the siphon part 20 does not need to provide a pump etc., washing | cleaning of a pump etc. is unnecessary. Moreover, since the siphon part 20 is comprised so that decomposition | disassembly is possible, the cleaning operation | work of the siphon part 20 can be performed easily. Thereby, all the paths through which water flows can be easily washed to maintain cleanliness.

  Moreover, in the water supply method which provides the siphon part 20, the water in the water container 2 is heated and boiled with the heater 3, and this water is guide | induced to the water channel 30 for cooling from the inside of the water container 2 by the siphon effect. Thus, since the water in the water container 2 is heated and boiled, the water in the water container 2 can be suitably sterilized by boiling.

  FIG. 6 is a perspective view of the outer tube 24 constituting the siphon unit 20 of the milk preparation apparatus 1 as viewed obliquely from below. As shown in FIG. 6, a convex portion 28 that protrudes inward is formed on the inner peripheral surface of the outer tube 24. Further, the convex portion 28 protrudes downward from the lower end portion of the outer tube 24.

  Thus, by forming the convex part 28 in the outer tube | pipe 24, the convex part 28 contact | abuts to the bottom face of the inner pipe | tube 23 (refer FIG. 5) and the container main body 21 (refer FIG. 5), and functions as positioning. Thereby, the gap | interval for each flowing water between the inner peripheral surface of the outer tube | pipe 24 and the inner tube | pipe 23 and between the lower end part of the outer tube | pipe 24 and the bottom face of the container main body 21 is ensured. Instead of the configuration in which the convex portion 28 is formed on the outer tube 24, a convex shape having the same function may be formed on the inner tube 23 or the bottom surface of the container body 21.

  Moreover, since the flow rate of water can be adjusted by adjusting the path of water in the siphon unit 20, water having a flow rate suitable for cooling can flow through the water channel 30 (see FIG. 4). Specifically, by appropriately setting the inner diameter of the outer tube 24, the outer diameter of the inner tube 23, the protruding height of the convex portion 28, etc., an appropriate amount of water is transferred from the water container 2 (see FIG. 5) to the heat sink 4 ( (See FIG. 4) can be delivered to the water channel 30, whereby milk at a suitable temperature can be prepared.

  Next, referring to FIG. 7, as an example in which the embodiment is modified, a milk preparation device 101 having a different water path will be described in detail. FIG. 7 is a block diagram showing an outline of a water path of the milk preparation apparatus 101 according to another embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the component which has the same or similar operation and effect as the already described embodiment.

  As shown in FIG. 7, the milk preparation device 101 is configured such that water flowing out of the water container 2 flows into the capsule 9 and then flows through the heat sink 4. Specifically, the capsule 9 is detachably disposed below the water container 2, and the heat sink 4 is detachably disposed below the capsule 9.

  With such a configuration, the milk preparation apparatus 101 prepares milk by dripping the water heated by the heater 3 into a capsule 9 and mixing it with milk powder M (see FIG. 2). The milk is cooled by the heat sink 4. Thereby, since the milk powder M in the capsule 9 is dissolved by the high-temperature water heated by the heater 3, the bactericidal action is also exhibited in the capsule 9, and the number of germs and the like can be further reduced.

  Moreover, the high-temperature milk prepared in the capsule 9 flows through the water channel 30 (see FIG. 4) of the heat sink 4 and is rapidly cooled. Thereby, the milk preparation apparatus 101 can prepare efficiently the milk of the temperature suitable for suckling.

  Moreover, since the water channel 30 for cooling the milk has a concave shape that opens upward as described above, the water channel can be easily washed. Thereby, propagation of miscellaneous bacteria etc. can be suppressed and the inside of waterway 30 can be kept hygienic. Thus, the heat sink 4 of the present invention capable of easily cleaning the water channel 30 is particularly suitable as a cooling means for cooling the high-temperature milk after mixing the high-temperature water and the milk powder M. .

  As mentioned above, although the milking apparatus which concerns on embodiment of this invention was demonstrated, this invention is not limited to this, A various change is possible in the range which does not deviate from the summary of this invention.
