Similarly, the control unit 7 is actually incorporated in the apparatus main body 2.

  Inside the apparatus main body 2 are a supply pipe 10, a heater 12 for heating the liquid L supplied through the supply pipe 10, a nozzle 14 for supplying the liquid L heated by the heater 12 to the milk preparation pot 4, and The hot water supply port 13 provided at the lower part of the nozzle 14, the rotation drive unit 5 (stirring unit) for rotating the stirring bar 4 a in the milk preparation pot 4, and the temperature of the milk M in the milk preparation pot 4 And a thermistor TM to be measured. The supply pipe 10 includes a float type check valve 11 that prevents the liquid L from flowing back to the storage tank 3. Further, the apparatus main body 2 incorporates a cooling unit 30 </ b> A (blower unit) for cooling the milk M generated in the milk preparation pot 4. For this reason, the liquid L stored in the storage tank 3 flows from the storage tank 3 into the inlet of the heater 12 via the float check valve 11 inside the supply pipe 10, and hot water is supplied from the outlet of the heater 12. It flows out to the mouth 13.

  As the supply pipe 10, for example, a pipe such as a metal pipe such as stainless steel (SUS) or aluminum, or a pipe made of silicon, polypropylene, or Teflon (registered trademark) can be used. As the material of the supply pipe 10, it is preferable to select, for example, a silicon-based member suitable for supply for food use. In this embodiment, as the supply pipe 10, for example, a silicon tube having an inner diameter of φ10 mm is used. The size of the material and inner diameter of the tube can be arbitrarily set. Further, in the powdered milk preparation device 1A, for the connection between the supply pipe 10 and each part, any fixing method suitable for the size of the supply pipe 10 and the like can be selected.

  The float check valve 11 has a function of preventing the backflow of the liquid L from the heater 12 to the storage tank 3.

In the present embodiment, the heater 12 has, for example, a U-shaped pipe shape as shown in FIG. 2 and is provided in the vicinity of the supply pipe 10. The heater 12 includes, for example, a nichrome wire, and has a function of heating and boiling the liquid L for milk production, sterilizing, and supplying the hot water 13 to the hot water supply port 13. Specifically, it is as the following (1) to (5).
(1) The liquid L flows from the storage tank 3 through the float check valve 11 to a U-shaped portion in the supply pipe 10 that is in the vicinity of the heater 12.
(2) The liquid L that has flowed into the U-shaped portion in the vicinity of the heater 12 in the supply pipe 10 is filled to a height at which the float check valve 11 is attached or higher.
(3) When heating by the heater 12 is started, the liquid L boils and is pushed up from the heater 12 by its vapor pressure.
(4) Since the float type check valve 11 is provided on the inlet side of the heater 12, the liquid L is pushed out only from the outlet of the heater 12 on the reverse side, and the liquid L is supplied to the hot water supply port 13 via the supply pipe 10. Is done.
(5) As the liquid L in the vicinity of the heater 12 in the supply pipe 10 decreases, the pressure in the vicinity of the heater 12 in the supply pipe 10 decreases, and the float check valve 11 opens. As a result, returning to (1), the liquid L before heating flows in.

  In addition, the heater 12 of this embodiment is provided with a temperature sensor (not shown) so that the heating temperature of the heater 12 can always be measured.

  The above (1) to (5) are repeated until the liquid L disappears from the storage tank 3, and the liquid L heated by the heater 12 is pumped to the hot water supply port 13. When the liquid L disappears inside the supply pipe 10, the heat from the heater 12 becomes difficult to be transmitted to the outside, and the temperature of the heater 12 itself is likely to rise above the boiling temperature of the liquid L. As a result, the heating of the heater 12 can be stopped by setting and detecting the upper limit temperature.

  The liquid L may be pumped from the heater 12 to a watering portion and a funnel (both not shown) provided in the supply pipe 10 or the nozzle 14.

In order to secure this gap d, the milk adjustment pot 4 has a structure that can be installed on the mounting portion 21 of the apparatus main body 2 only by a sliding operation.

  Further, the lid portion 45 of the milk preparation pot 4 is not provided with holes except for the hole portions 451 in the portion where the air flow path 34 does not exist. As a result, the hermeticity in the milk preparation pot 4 is further improved, and foreign matters such as dust fall from the upper part of the milk preparation pot 4 to the milk M through a portion where the air flow passage 34 does not exist. There is no risk of being mixed in.

  In FIGS. 5A to 5C, the air flow path 34 is at least partially annular when viewed from above, but is not limited to such a configuration, and at least some The outer periphery may be configured to extend along the peripheral edge of the lid portion 45, and depends on the shape of the peripheral edge of the lid portion 45. Further, as can be seen from FIG. 5B, it can be said that the air flow passage 34 is formed in a tubular shape (duct shape) because it is substantially hollow.

  By the way, as a method of cooling the milk M in the milk preparation pot 4, it can be considered that air sent from the fan 32 is directly applied to the milk M via the filter 31a. However, when the wind sent from the fan 32 is directly applied to the milk M, there is a possibility that foreign matters such as finer dust that cannot be completely removed by the filter 31a are mixed into the milk M. When dust or the like touches the milk M, it is trapped and taken in the milk M by surface tension. For this reason, the method of directly applying the wind sent from the fan 32 to the milk M is not desirable as a method of creating a drink to be drunk to the baby.

  Even if the air flow is directly applied from the fan 32 to the milk M, normally, the air flow strongly hits only a part of the liquid surface. For this reason, the part which contributes to the cooling in the milk M becomes only a part which the airflow hits. Therefore, the entire liquid level of the milk M cannot be efficiently used for cooling.

  The cooling unit 30A of the present embodiment includes a cooling mechanism for dealing with these problems.

(Cooling mechanism of cooling unit 30A)
The cooling mechanism of the cooling unit 30A will be described below.

  When the fan 32 is operating, a main airflow AF1 is generated in the air flow path 34, where the horizontal component has a relatively high flow rate. As shown in FIG. 5C, the main airflow AF1 is a swirling airflow along the outer peripheral inner wall 34f of the air flow path 34, and flows in the horizontal direction from the upstream inlet 34b to the downstream outlet 34c. . In other words, the main air flow AF1 is a swirling flow that flows in a plane substantially parallel to the liquid level of the milk M that is left in the milk preparation pot 4. Therefore, the airflow generated by the fan 32 does not directly hit the milk M in the milk preparation pot 4, and a main airflow is a swirling flow in which a part of the airflow flows in a plane substantially parallel to the liquid level of the milk M. After being converted to AF1, the liquid level of the milk M is indirectly contacted while turning on the liquid level of the milk M in the milk preparation pot 4.

  As shown in FIGS. 2 and 5, air is exchanged between the inside of the air flow path 34 and the inside of the milk preparation pot 4 through the hole 452. By this exchange of air, the main air flow AF1 is diverted from the hole 452 into the milk preparation pot 4 along the outer peripheral inner wall 34f of the air flow passage 34, and a sub air flow AF2 is generated. The sub-airflow AF2 is a swirling flow that swirls on the liquid level of the milk M in the milk preparation pot 4, as shown in FIG.

  In the milk preparation pot 4, the milk M is cooled by the sub-airflow AF <b> 2 that is a swirling flow coming into contact with the liquid surface of the milk M. More specifically, the sub-airflow AF2, which is a swirling flow divided into the milk adjustment pot 4, hits the liquid level of the milk M while swirling along the inner wall of the milk adjustment pot 4, and attracts the hot air of the milk M. To do. As a result, heat is removed from the milk M. The auxiliary airflow AF <b> 2 that has taken heat from the milk M in this way becomes warm air, and therefore rises toward the air flow path 34. Then, the auxiliary airflow AF2 merges with the main airflow AF1 by exchanging with the air in the air flow path 34 through the hole 452, and is finally discharged from the downstream outlet 34c to the outside of the apparatus main body 2.

  However, as shown also in FIG. 2, the turning direction of the main airflow AF1 and the subairflow AF2 is opposite to the direction in which the stirrer 4a, that is, the liquid (milk M) in the milk preparation pot 4 is rotated.

  The sub airflow AF2 that is a swirling flow generated in the milk adjustment pot 4 is a shunt of the main airflow AF1 that is a swirling flow in the air flow passage 34. Therefore, the sub airflow AF2 is horizontal to the liquid level of the milk M from the upstream side to the downstream side of the main airflow AF1 in the same manner as the main airflow AF1. For this reason, the secondary airflow AF2 that hits the liquid level of the milk M on the upstream side of the main airflow AF1 takes heat from the milk M, becomes warm air, and flows to the downstream side of the main airflow AF1.

  Here, as described above, the holes 452 are provided at a plurality of positions from a position corresponding to the upstream inlet 34b to a position corresponding to the downstream outlet 34c. Therefore, the secondary airflow AF2 that hits the liquid level of the milk M on the upstream side of the main airflow AF1 takes heat from the milk M and is discharged into the hole 452 on the downstream side of the main airflow AF1. In other words, the auxiliary airflow AF2 enters the milk adjustment pot 4 from the air flow path 34 through the hole 452 on the upstream side of the air flow path 34, flows through the upper portion of the milk adjustment pot 4, and flows into the air flow path 34. An airflow component that returns to the air flow path 34 through the hole 452 is formed on the downstream side of the airflow. Due to this airflow component, the hot air of the milk M attracted by the auxiliary airflow AF2 can be smoothly discharged from the hole 452 to the air flow path 34.

  In the present embodiment, the airflow flowing in the air flow path 34 becomes faster near the upstream side of the fan 32 due to the airway resistance and fine leakage in the middle, and the airflow speed in the air flow path 34 increases. The air pressure is higher than that in the milk pot 4. On the other hand, the speed of the airflow is reduced toward the downstream side, and the air pressure is lower than that in the milk preparation pot 4. For this reason, out of the plurality of holes 452, in the hole 452 arranged on the upstream side of the main airflow AF1, the heat of the milk M is taken away from the milk adjustment pot 4 and the auxiliary airflow AF2 discharged to the air flow path 34. The amount of air that enters the milk preparation pot 4 and becomes the auxiliary airflow AF2 is larger than the amount. On the other hand, among the plurality of holes 452, the hole 452 disposed on the downstream side of the main airflow AF1 takes heat from the milk M more than the amount of air that enters the milk adjustment pot 4 and becomes the auxiliary airflow AF2. The amount of the secondary airflow AF2 discharged from the milk adjustment pot 4 to the air flow path 34 is larger. That is, on the upstream side, air mainly flows into the milk adjustment pot 4 from the air flow path 34 side, and on the downstream side, air is mainly discharged from the milk adjustment pot 4 to the air flow path 34 side. . In the present embodiment, a plurality of hole portions 452 are provided, and are mainly different between an upstream side where air flows into the milk preparation pot 4 and a downstream side where air is mainly discharged from the milk adjustment pot 4. Since the hole 452 is assigned, air can be more efficiently flowed in and out than a form having one hole.

  In this way, the cooling unit 30A does not directly apply the air flow generated by the fan 32 from the direction perpendicular to the liquid level of the milk M, but indirectly the horizontal main air flow AF1 generated by the fan 32. The sub-airflow AF2 is generated in the milk preparation pot 4 by diversion. In the cooling unit 30A, the milk M is cooled by applying the indirectly divided sub-airflow AF2 to the liquid surface of the milk M. The sub airflow AF2 in the milk preparation pot 4 is not a part of the liquid surface but the entire liquid surface because the flow velocity of the horizontal airflow component flowing along the liquid surface of the milk M is relatively fast. As a result, according to the cooling unit 30A, heat can be efficiently taken from the entire liquid surface of the milk M, and efficient cooling of the milk M can be realized.

  In addition, since the flow velocity of the airflow component in the horizontal direction of the auxiliary airflow AF2 is relatively fast, the cooling unit 30A is trapped in the milk M as compared with the configuration in which the airflow is applied from the direction perpendicular to the liquid level of the milk M. Foreign matter such as dust can be reduced.

  Moreover, it is preferable that the shape of the periphery of the milk preparation pot 4 is circular shape, and the ventilation flow path 34 centered on the center of the milk adjustment pot 4, as shown to (c) of FIG. It extends along the arc shape of the periphery. Therefore, a part of the shape of the air flow path 34 is annular. Therefore, the main airflow AF1 flowing through the air flow path 34 becomes a swirling flow, and centrifugal force is generated in the main airflow AF1.

  Therefore, even if the main airflow AF1 contains foreign matter such as dust, the foreign matter flows along the outer peripheral inner wall 34f on the outer peripheral side of the air flow channel 34 by centrifugal force, and the foreign matter flows from the hole 452 to the milk adjustment pot 4 Intrusion into the is suppressed.

  Further, in the cooling unit 30 </ b> A according to the present embodiment, it is preferable that the upstream inlet 34 b of the air flow path 34 is opened in the annular tangential direction of the air flow path 34. Thereby, the main airflow AF1 which is a swirl flow can be efficiently generated in the air flow passage 34.

  In addition, in the case where a part of the shape of the air flow path 34 is an annular shape, the air flow path 34 is formed at the periphery of the milk adjustment pot 4 in order to form the auxiliary air flow AF2 that is the swirl flow described above. Of these, it preferably extends along a peripheral region corresponding to an angle of 90 degrees or more with the center at the center. In this case, the hole 452 is also formed over an angle of 90 degrees or more around the center from the upstream side to the downstream side of the air flow path 34.

  Further, as shown in FIG. 5C, the hole 452 formed in the lid 45 attached to the milk adjustment pot 4 faces the air flow path 34, and the shape of the air flow path 34 is Similarly, since the widths thereof are also the same, when the main air flow AF1 in the air flow passage 34 is diverted into the milk preparation pot 4 through the diverging hole 452, and when the auxiliary air flow in the milk adjustment pot 4 is reached. The airflow AF2 merges with the main airflow AF1 in the air flow path 34 through the hole 452. For this reason, the main airflow AF1 in the air flow path 34 enters the milk adjustment pot 4 as a swirl flow through the hole 452 while maintaining the directivity. The sub airflow AF2 in the milk adjustment pot 4 is discharged from the milk adjustment pot 4 as a swirl flow through the hole 452 while maintaining the directivity, and merges with the main airflow AF1. Therefore, in addition to less contamination of the milk M with foreign matters such as dust, very efficient air cooling can be realized.

  Further, the milk adjustment pot 4 is arranged so as to be separated from the outer peripheral inner wall 34 f of the air flow path 34 with respect to the peripheral edge of the hole 452 of the lid 45. 5C, the center position 33M of the hole 452 is located outside the center position 34M in the width direction W of the air flow path 34. The “width direction W” here is also referred to as a direction perpendicular to the direction of the main airflow AF1 or the radial direction of the ring formed by the air flow passage 34.

  Foreign matter such as dust contained in the main airflow AF1 flows along the outer peripheral inner wall 34f by centrifugal force. Therefore, since the peripheral edge of the hole 452 is separated from the outer peripheral inner wall 34f, foreign matters such as dust are less likely to enter the milk preparation pot 4 from the hole 452. Thereby, it is suppressed that foreign matters, such as dust, mix in milk M. Here, a plurality of hole portions 452 are provided, and the peripheral edges of all the hole portions 452 may be provided apart from the outer peripheral inner wall 34f. As a result, the main airflow AF1 containing foreign matters such as dust flowing through the air flow passage 34 and the flow of the sub-airflow AF2 entering the milk preparation pot 4 are separately formed. As a result, while the milk M is efficiently cooled by the auxiliary airflow AF2, it is possible to suppress the entry of foreign matters such as dust into the milk M.

  Further, the shape of the peripheral edge of the hole 452 is a shape that is long in the direction in which the air flow path 34 extends. As a result, the airflows of the main airflow AF1 and the subairflow AF2 are easily exchanged, and the milk M can be efficiently cooled.

  Moreover, the clearance gap d between the cover part 45 and the opening 34a of the ventilation flow path 34 is 5 mm or less, and is very small. For this reason, the risk that foreign matter such as dust is mixed with the outside air from the gap d into the milk preparation pot 4 is reduced. Moreover, when the clearance gap d between the cover part 45 and the opening 34a of the ventilation flow path 34 is 5 mm or more, an airflow will leak from the clearance gap d, and it will be in the liquid level of the milk M in the milk adjustment pot 4. The sub-airflow AF2 that is the swirling flow along is less likely to occur. Therefore, ventilation efficiency can be improved.

  Further, the cooling unit 30A of the present embodiment has a configuration in which a blower fan 32 is connected to an upstream side inlet 34b of the blower flow path 34 as an airflow generation unit. However, the air flow generation unit of the cooling unit 30 </ b> A according to the present embodiment is not limited to the fan 32, and is not particularly limited as long as the main air flow AF <b> 1 can be generated in the air flow path 34. For example, the air flow generation unit may be a suction pump connected to the downstream outlet 34 c of the air flow path 34.

(Additional notes)
In the present embodiment, the guide 212 is formed from the center portion to the rear portion of the placement surface 211, but may be formed from the front portion to the rear portion of the placement surface 211. However, the former is preferable compared to the latter, so that the milk adjustment pot 4 can be first placed on the placement surface 211 and then slid toward the guide 212, so that the placement surface can be stabilized. It can be slid to a fixed position 211.

  Further, the ratio of the width of the guide 212 to the width of the bottom surface of the milk preparation pot 4 in contact with the placement surface 211 is preferably 50% or more and less than 100%, and is 70% or more and less than 100%. Is more preferable. As a result, the width of the guide 212 becomes larger than the width of the milk adjustment pot 4, and therefore the operation of moving the milk adjustment pot 4 along the guide 212 can be performed stably.

  By the way, the placement surface 211 of the apparatus main body 2 adjusts the milk adjustment pot 4 when horizontally moving from the near side (placement start position) to the fixed position (placement end position) of the placement surface 211. It is desirable to have a gradient so that the pot 4 gradually rises upward. In this case, strictly speaking, the placement surface 211 is slightly tilted from the horizontal direction, and the front part is lowered rather than the rear part. For this reason, when putting the milk preparation pot 4, it is easy to put the milk preparation pot 4 because a sufficient gap can be made with respect to the restricting portion 24 (opposite portion), and the milk preparation is performed. When the pot 4 is moved to a fixed position, the gap with respect to the restricting portion 24 (opposing portion) can be reduced, so that leakage of airflow from the gap and entry of foreign matters can be reduced.

  On the other hand, when the mounting surface 211 has an inclined structure as described above, when the milk adjustment pot 4 is mounted, the normal milk adjustment pot 4 is inclined obliquely. Therefore, in the milk preparation pot 4, it is preferable that the thickness of the bottom portion 41 becomes thinner from the handle 44 side toward the spout 43 side so as to correspond to the gradient. In this case, when the milk adjustment pot 4 is installed at a predetermined position on the placement surface 211, the bottom surface in the milk adjustment pot 4 can be set in the horizontal direction.

1 A of powdered milk preparation apparatuses which concern on other embodiment of this invention are the points where the groove | channel 411 of the bottom face of the pot 4 for milk preparation is changed compared with the powdered milk preparation apparatus 1A shown in FIGS. The other configurations are the same.

  FIG. 6 is a perspective view of the milk preparation pot 4A according to the present embodiment as viewed from below. As shown in FIG. 6, a groove 413 is formed on the bottom 41 of the milk adjustment pot 4 </ b> A for fitting with the guide 212 of the placement unit 21. In the present embodiment, at the bottom 41, U-shaped protrusions 414 are provided on both sides in the direction from the spout 43 side to the handle 44 side and on the handle 44 side, so that the groove 413 is formed. Thereby, the groove | channel 413 is opened in the direction from the spout 43 side to the handle 44 side. The groove 413 is open on the side of the spout 43 and closed on the side of the handle 44.

  The interval between the projecting portions 414 corresponds to the width of the guide 212 of the placement portion 21, but the tip portions 414 a and 414 a on the spout 43 side are widened. In addition, a base portion 414 b that is a portion on the handle 44 side of the protruding portion 414 has a shape in which the distal end portion 212 a of the guide 212 is fitted. Further, the protruding portion 414 has a recessed portion other than the peripheral portion.

  When the milk adjustment pot 4A having the above-described configuration is moved to the placement surface 211 of the apparatus main body 2 illustrated in FIG. 1, the guide is compared with the case where the milk adjustment pot 4 illustrated in FIG. 3 is moved to the placement surface 211. The tip 212a of 212 is brought into contact with the base 414b of the projecting portion 414 and stopped, and the installation of the milk preparation pot 4A on the apparatus main body 2 is completed, and the other operations are the same. As described above, in this embodiment, the distal end portion 212 a of the guide 212 and the base portion 414 b of the protruding portion 414 serve as a positioning mechanism for installing the milk preparation pot 4 </ b> A at a predetermined position on the placement surface 211.

  Further, in the milk preparation pot 4A of the present embodiment, as shown in FIG. 6, two linear ribs 415 and 415 extend from the base portion 414b of the protruding portion 414 to the spout 43 side. The height of the ribs 415 decreases from the handle 44 side toward the spout 43 side so as to correspond to the gradient on the placement surface 211.

  Accordingly, when the milk preparation pot 4A is installed at a predetermined position on the placement surface 211, the bottom surface in the milk adjustment pot 4 can be set in the horizontal direction, and the thickness of the bottom 41 of the milk adjustment pot 4A There is no need to change.

[Embodiment 3]
A powdered milk preparation apparatus 1A (apparatus main body 2A) according to another embodiment of the present invention is substantially the same as the powdered milk preparation apparatus 1A (apparatus main body 2) shown in the first and second embodiments, and is different. The contents will be described in detail. In addition, the lid 45A in the present embodiment is different from the lid 45 described in the first and second embodiments, and therefore the details thereof will be described.

  7A and 7B are perspective views showing an external configuration of the lid portion 45A. FIG. 7A is a perspective view of the lid portion 45A viewed from obliquely above. FIG. 7B is a perspective view of the lid portion 45A viewed obliquely from below. is there. 8 is a six-sided view of the lid portion 45A, (a) is a plan view of the lid portion 45A, (b) is a front view of the lid portion 45A, and (c) is the back surface of the lid portion 45A. (D) is a left side view of the lid portion 45A, (e) is a right side view of the lid portion 45A, and (f) is a bottom view of the lid portion 45A. Further, FIG. 9 is a cross-sectional view taken along line IX-IX shown in FIG.

  Hereinafter, the lid portion 45A will be described with reference to FIGS. 7 to 9. However, in the case where the lid portion 45A is described using a direction, the vertical direction in a state where the lid portion 45A is attached to the milk adjustment pot 4A. Is described as the vertical direction of the lid 45A. In addition, while explaining the state in which the milk adjustment pot 4A with the lid 45A mounted thereon is placed at a fixed position of the apparatus main body 2A as viewed from the front of the apparatus main body 2A, the left-right direction is described as the left-right direction of the lid 45A. The front-rear direction in which the milk adjustment pot 4A moves when the milk adjustment pot 4A is placed at a fixed position of the apparatus main body 2A will be described as the front-rear direction of the lid 45A.

  As shown in FIGS. 7 to 9, the lid 45 </ b> A is formed in a substantially disk shape and includes a substantially circular main body 450. The front end portion (hereinafter, also referred to as “tip portion”) of the main body 450 (lid portion 45A) is formed in a straight line with a part of the arc omitted (removed), and the rear end of the lid portion 45A An extending portion 450b described later is provided in the portion. The main body 450 is formed with one hole 451 and a plurality (four in this embodiment) of holes 452 (holes 452a, 452b, 452c, 452d).

  In the following description, when it is necessary to distinguish the four holes 452, they are referred to as holes 452a, 452b, 452c, and 452d, but when it is not necessary to distinguish, the holes 452 are simply referred to as holes 452. I will decide.

  The hole 451 is formed at the center of the main body 450, and the four holes 452 are formed along the edge (outer periphery) of the main body 450. The hole 451 has a circular shape, and the hole 452 has a shape obtained by bending an ellipse along the edge (arc) of the main body 450. In addition, an annular projecting portion 451 a projecting upward from the main body portion 450 and an annular projecting portion 451 b projecting downward from the main body portion 450 are formed at the outer peripheral portion of the hole portion 451.

  Moreover, the shape of the hole part 451 and the hole part 452 shown in FIG. 7 and FIG. 8 is an example, and should not be limited. For example, the hole 451 may be a polygon. The hole 452 may have a shape obtained by curving a rectangle along an arc.

  Further, the main body 450 is provided with two notches 450a extending in parallel to a straight line perpendicular to the tangential direction of the outer periphery thereof, and the main body from the part of the main body 450 sandwiched between the two notches 450a. An extended portion (or extended portion) 450b that extends (extends) toward the outside of 450 is provided. The extending portion 450b can be moved in the vertical direction, and a part of the main body 450 sandwiched by the notches 450a is deformed (bent) in the vertical direction according to the vertical movement of the extending portion 450b.

  The four holes 452 are arranged separately on the left and right sides with two notches 450a provided in the main body 450 interposed therebetween. The reason why the four holes 452 are arranged separately on the right and left in this way is to efficiently suck and discharge the wind from the cooling unit 30A. In addition, the four holes 452 are provided when the two adjacent holes 452 are formed as one continuous hole, and when the milk M is poured into the baby bottle, the stirring bar 4a is adjusted through the holes 452. This is to prevent this from jumping out of the milk pot 4A. Therefore, in this embodiment, the size (length in the longitudinal direction) of each hole 452 is set to be shorter than the diameter of the stirring bar 4a. Furthermore, if the adjacent two hole portions 452 are made one continuous hole portion, the strength of the lid portion 45A is reduced at the portion where the hole portion 452 is formed.

  Further, as can be seen from (a) and (f) of FIG. 8, the four hole portions 452 are arranged close to the rear end portion (the extending portion 450 b side) of the main body portion 450. In the present embodiment, the air flow path 34 through which the main airflow AF1 flows has an arc shape that is biased toward the front side so that the user can easily clean the portion of the air flow path 34 of the apparatus main body 2A. The reason why the four holes 452 are arranged close to the extending portion 450b side (front side) is to arrange each hole 452 on the path of the main airflow AF1.

  A protruding portion (engaging portion) 450c protruding upward is provided on the upper surface of the extending portion 450b. As can be seen from FIGS. 8D, 8E, and 9, the protrusion 450c has an inclined surface 4500 on the front side of the main body 450 and a vertical surface 4502 on the rear side of the main body 450. ing. As described above, the inclined surface 4500 is provided on the projecting portion 450c because the milk adjustment pot 4A to which the lid portion 45A is attached is placed on the apparatus main body 2A without the user pressing down on the extending portion 450b. This is because the protrusion 450 c is engaged with a recess (engaged portion) 35 (see FIG. 13) formed on the lower surface of the restricting portion 24. Further, the vertical surface 4502 is provided on the projecting portion 450c when the milk adjustment pot 4A to which the lid portion 45A is attached is placed at a fixed position of the apparatus main body 2A without the user pressing down on the extending portion 450b. For example, the state in which the protrusion 450c is engaged with the recess 35 cannot be released.

  A guide groove 450d is provided on the upper surface of the main body 450 and on the opposite side, that is, the front side of the extending portion 450b with the hole 451 interposed therebetween. The guide groove 450d includes a mortar-shaped concave portion 4504 disposed at the rear end portion thereof, and a groove 4506 extending from the concave portion 4504 toward the outer periphery (front end) of the main body portion 450. That is, the guide groove 450d is formed to extend in the front-rear direction of the lid portion 45A. However, the joint between the recess 4504 and the groove 4506 is above the bottom surface of the recess 4504. Further, the groove 4506 has a slope that is lowered (inclined downward) from the concave portion 4504 side toward the outer periphery (from the rear to the front).

  As described above, the guide groove 450d is provided with the concave portion 4504 when the milk preparation pot 4A to which the lid portion 45A is attached is placed at a fixed position of the apparatus main body 2A. This is for accommodating the tip of the contact pin 241a of the detected portion 241. In this state, the movement of the lid 45A in the horizontal direction is restricted.

  Further, the groove 4506 provided in the guide groove 450d has a slope when the milk adjustment pot 4A with the lid 45A attached is attached to the apparatus main body 2A. This is because the contact pin 241a is gradually pushed in as it is moved (switch is turned on or off).

  Furthermore, a substantially annular projecting portion 450f that projects upward is provided on the outer peripheral portion of the upper surface of the main body 450. That is, the upper surface of the main body 450 has an ascending step at the outer peripheral portion (edge portion).

  Further, in the lid portion 45A of the present embodiment, there is a substantially annular wall portion (leg portion) 450g extending downward from the outer peripheral portion, excluding the portion sandwiched between the two notches 450a, which is the lower surface of the main body portion 450. Provided. Further, a wall portion (leg portion) 450h similar to the wall portion 450g is provided below the extending portion 450b.

  The diameter of the outer periphery of the circle formed by the wall 450g and the wall 450h is the same as or substantially the same as the inner diameter of the opening 42 of the milk adjustment pot 4A, and the wall 450g is the opening 42 of the milk adjustment pot 4A. The lid 45A is attached to the milk preparation pot 4A. The wall portion 450g has the largest vertical width (height) on the side where the extending portion 450b is provided and the smallest vertical width on the side where the tip portion of the guide groove 450d is provided, and guides from the extending portion 450b side. The width is gradually reduced toward the tip of the groove 450d. This is because the notch 450a and the hole 452 are formed in the main body 450 on the side where the extending portion 450b is provided, so that the strength of the lid 45A is secured (reinforced). Further, the wall 450h prevents a gap from being formed at the lower end of the notch 42a (see FIG. 10) provided in the milk preparation pot 4A. Furthermore, since the front end of the guide groove 450d is disposed at a position corresponding to the spout 43 of the milk preparation pot 4A, the milk M is not disturbed when poured into the baby bottle. Further, in order to prevent the milk M from getting in the way when it is poured into the baby bottle, the height of the wall 450h is another part of the wall 450h corresponding to the spout 43 of the milk preparation pot 4A. A notch 4508 directed upward is provided so as to be lower.

  Further, a protrusion is provided on the outer peripheral surface of the wall 450g and at the tip of the guide groove 450d. In the present embodiment, the protrusions are two protrusions (projections) 450i extending in the height direction (vertical direction) of the wall 450g. For example, the two protrusions 450i extend in a direction perpendicular to the upper surface or the lower surface of the main body 450 of the lid 45A. In the present embodiment, the two protrusions 450i are provided at the tip of the guide groove 450d with a predetermined interval therebetween. This predetermined interval corresponds to the horizontal width (left and right width) of the spout 43 of the milk preparation pot 4A, is on the handle 44 side of the milk preparation pot 4A, and is the horizontal width of the notch 42a provided on the top of the handle 44. Wider than. Therefore, when the lid 45A is attached to the milk adjustment pot 4A, when the two protrusions 450i are located at a portion other than the spout 43, at least one of the two protrusions 450i is the edge of the opening 42 (adjustment). The wall portion 450g does not fit into the open portion 42 by being caught on the upper edge of the milk pot 4A. That is, the two protrusions 450i are members (erroneous mounting prevention members) that prevent the lid portion 45A from being mounted in the milk preparation pot 4A in an incorrect direction (see FIG. 12). Therefore, the lid 45A can be attached to the milk preparation pot 4A in the correct orientation.

  However, since the extending portion 450b can be moved in the vertical direction as described above, the lateral width of the notch 42a is set larger than the lateral width of the extending portion 450b (see FIG. 10). Further, since the engagement (lock) between the protrusion 450c and the recess 35 is released by pushing down the extending portion 450b, the vertical width of the notch 42a is determined to be a height at which the lock is released.

  In the present embodiment, the two protrusions 450i are provided at the position corresponding to the spout 43 on the outer peripheral surface of the wall 450g. However, the present invention is not limited to this. As another example, two protrusions 450i may be provided at the end portion on the side where the extending portion 450b is provided. In such a case, the lateral width of the notch 42a is set wider than the lateral width of the spout 43, and the predetermined interval between the two protrusions 450i is set to a length corresponding to the lateral width of the notch 42a. Therefore, as described above, it is possible to prevent the lid 45A from being attached to the milk preparation pot 4A in the wrong direction.

  In the present embodiment, the two protrusions 450i are provided on the distal end side of the guide groove 450d because the lid 45A is provided between the wall 450g and the wall 450h when the lid 45A is attached to the milk preparation pot 4A. This is to cover the gap with the side wall of the milk preparation pot 4A as much as possible. For this reason, the liquid in the milk preparation pot 4A leaks outside through the gap, the swirl flow leaks out through the gap, or foreign matters such as dust enter the milk M in the milk adjustment pot 4A through the gap. Mixing can be prevented as much as possible.

  FIG. 10 is a perspective view of the milk preparation pot 4A as viewed from the handle 44 side obliquely from above with the lid 45A attached to the milk preparation pot 4A. FIG. 11 is an illustrative view showing a state before and after mounting the lid 45A on the milk preparation pot 4A. FIG. 11 (a) shows the side of the pouring spout 43 of the milk preparation pot 4A obliquely from above before the mounting. (B) is the perspective view which looked at the spout 43 side of the pot 4A for milk preparation from diagonally upward in the state after mounting | wearing. FIG. 12 is a perspective view of the milk preparation pot 4A viewed from obliquely above the handle 44 in a state in which the orientation of the lid 45A is erroneously attached to the milk adjustment pot 4A.

  As can be seen from FIGS. 10 and 11, the four holes 452 provided in the lid 45A are formed along the edge of the opening 42 of the milk adjustment pot 4A in relation to the milk adjustment pot 4A. The However, since the lid 45A is attached to the opening 42 of the milk adjustment pot 4A, the four holes 452 are formed inside the edge of the opening 42.

  Further, as shown in FIGS. 8A and 8F, in the lid portion 45A, the extending portion 450b, the protruding portion 450c, the hole portion 451, and the guide groove 450d are arranged in a straight line. Therefore, as shown in FIGS. 10 and 11, when the lid portion 45A is attached to the milk preparation pot 4A, the extending portion 450b is disposed above the position where the handle 44 is provided, and the tip of the guide groove 450d The part is disposed above the spout 43. That is, the handle 44, the protrusion 450c, and the guide groove 450d are also arranged on a straight line.

  Moreover, as shown in FIG. 11, the length (width) in which the tip of the lid 45A is formed in a straight line corresponds to the left and right widths of the spout 43 of the milk preparation pot 4A.

  Furthermore, as described above, the two protrusions 450i are provided at the tip of the lid portion 45A, and the predetermined interval between these two protrusions 450i is the same as or substantially the same as the left and right widths of the spout 43. Is set to (narrow). Since the width of the notch 42a is narrower than the width of the spout 43, the two protrusions 450i are located at positions corresponding to the spout 43 when the lid 45A can be attached to the milk preparation pot 4A. Will be directed.

  Therefore, as shown in FIG. 11, when the two protrusions 450i are directed to the position corresponding to the spout 43 and the lid portion 45A is attached to the milk preparation pot 4A, the wall portion 450g fits into the opening portion 42. . That is, the lid 45A is correctly attached to the milk preparation pot 4A.

  However, for example, as shown in FIG. 12, when the two protrusions 450i are directed to the positions corresponding to the notches 42a and the lid 45A is to be attached to the milk adjustment pot 4A, the protrusions 450i are adjusted. The wall portion 450g does not fit into the opening portion 42 by being caught on the edge of the opening portion 42 of the milk pot 4A. That is, the lid 45A is not attached to the milk preparation pot 4A.

  Note that FIG. 12 is merely an example, and when the two protrusions 450 i are displaced from the position corresponding to the spout 43, the wall portion 450 g does not fit into the opening portion 42.

  13 is a perspective view of the powdered milk preparation device 1A (device main body 2A) shown in FIG. 1 as viewed obliquely from below. FIG. 14 is a schematic diagram for explaining the guide portion 34h. FIG. 15 is a cross-sectional view showing an example of a cross section when the milk preparation pot 4A with the lid 45A attached is placed on the placement surface 211 of the powdered milk preparation device 1A (device main body 2A).

  As can be seen from FIG. 13, a concave portion 221 is formed in the wall portion 22. As shown in FIG. 15, the pouring spout 43 of the milk adjustment pot 4 </ b> A is accommodated in the recess 221 when the milk adjustment pot 4 </ b> A is placed at the correct position of the placement portion 21.

  Further, on the lower surface of the restricting portion 24, that is, the facing surface facing the placement surface 211, the milk adjustment pot 4 </ b> A with the lid portion 45 </ b> A is placed at the correct position (fixed position) of the placement portion 21. In this case, the detection unit 241 in which the contact pin 241a is disposed at a position facing the recess 4504 of the guide groove 450d provided in the lid 45A is provided. The detection unit 241 includes a mechanical switch that is turned on or off when the contact pin 241 a is pressed, and an electrical signal corresponding to the on / off of the switch is input to the control unit 7.

  The detection unit 241 is a device that mainly detects from the upper side (above) of the lid 45A whether the lid 45A is attached to the milk preparation pot 4A. However, as described above, the contact pin 241a is located at a position facing the concave portion 4504 of the guide groove 450d provided in the lid portion 45A when the milk adjustment pot 4A is placed at the correct position of the placement portion 21. Since it is provided, the detection unit 241 is also a device for detecting whether the milk adjustment pot 4A is correctly placed.

  When the milk adjustment pot 4A to which the lid 45A is attached is attached to the apparatus main body 2A, the contact pin 241a slides in the groove 4506 of the guide groove 450d. However, what is actually moving is the lid 45A having the guide groove 450d. Therefore, it is possible to prevent the orientation of the milk preparation pot 4 </ b> A from being wrong when attached.

  Although not shown, the contact pin 241a is urged downward by an elastic member such as rubber or a spring. Accordingly, when the milk adjustment pot 4A to which the lid 45A is attached is attached to the apparatus main body 2A, the contact pin 241a is pushed down by the restoring force of the elastic member and fits (contains) in the recess 4504. For this reason, the depth of the recess 4504 is set to a depth at which it can be detected that the switch is turned on or off and the lid 45A is correctly attached. As described above, in the lid portion 45A, the groove 4506 is moved along the contact pin 241a and is guided to the detection position by the detection portion 241.

  Further, as described above, in the present embodiment, the handle 44, the protruding portion 450c, and the guide groove 450d are arranged on a straight line. For this reason, when attaching or removing the milk adjustment pot 4A with the lid 45A attached to the apparatus main body 2A, a load is not applied in a direction different from the direction in which the milk adjustment pot 4A is moved. Therefore, even if the guide 212 of the apparatus main body 2A and / or the protruding portion 414 of the milk adjustment pot 4A is not provided, the milk adjustment pot 4A is difficult to rotate in the horizontal plane. Therefore, the user can smoothly attach and remove the milk preparation pot 4A with one hand.

  In the present embodiment, the detection unit 241 having the contact pin 241a and the mechanical switch is provided, but the present invention is not limited to this. An optical sensor or a magnetic sensor may be used. For example, a reflective optical sensor is used, and a coating that reflects light or does not reflect light is applied to a position corresponding to the concave portion 4504 of the lid 45A, and the lid is applied according to the output of the optical sensor. It is possible to detect whether or not the portion 45A is mounted. When a magnetic sensor is used, whether or not the lid 45A is attached according to the output of the magnetic sensor by embedding a magnet or applying a magnetic paint at a position corresponding to the concave portion 4504 of the lid 45A. Can also be detected. That is, various mechanisms can be adopted as a mechanism for detecting the lid 45A.

  In this embodiment, the guide groove 450d is provided in the lid portion 45A. However, a U-shaped protruding portion 414 is provided on the bottom 41 of the milk adjustment pot 4A, and the protruding portion 414 serves as a guide. In order to fit to 212, the milk adjustment pot 4 </ b> A is attached to the guide 212 in the correct orientation. For this reason, the guide groove 450d is not necessarily provided. Even in such a case, the contact pin 241a can be pressed on the upper surface of the lid 45A, and it can be detected that the lid 45A is mounted.

  The agitation system of the present embodiment is considered so as to reduce leakage of high-temperature steam from the gap between the milk preparation pot 4A and the regulating portion 24 as much as possible during use. For that purpose, it is necessary not only to attach the milk adjustment pot 4A to the correct position (fixed position) of the placement portion 21, but also to correctly attach the lid portion 45A to the milk adjustment pot 4A. In the stirring system of the present embodiment, whether the lid 45A is correctly mounted as well as the mounting state as to whether or not the milk adjustment pot 4A is placed at the correct position (fixed position) of the mounting portion 21. It is possible to simultaneously determine the mounting state of the lid as to whether or not it is used in an inappropriate state such as when the lid 45A is incorrectly mounted, and the structure is designed with safety in mind. ing.

  Further, a hot water supply port 13 is provided on the lower surface (opposing surface) of the restricting portion 24 and is a part of the opposing surface, and a concave portion 242 that is recessed upward is formed around the hot water supply port 13. Therefore, the lower end portions of the hot water supply port 13 and the nozzle 14 protrude from the facing surface and are exposed. For this reason, even if the liquid splatters from the hot water supply port 13 in the lateral direction, the facing surface is difficult to adhere, and when a droplet adheres to the nozzle 14 itself, the milk adjustment pot 4A below the lower end of the nozzle 14 The liquid will drop out.

  However, the hot water supply port 13 is disposed in the same plane as the facing surface or above the facing surface. This is to prevent the lower end portion (hot water supply port 13) of the nozzle 14 from coming into contact with the upper surface of the lid portion 45A when the milk preparation pot 4A is attached to the apparatus main body 2A while moving in parallel. is there.

  If the concave surface 242 is not formed on the opposed surface and is completely flat, there is almost no gap between the opposed surface and the upper surface of the lid 45A, so that the lower end of the nozzle 14 protrudes from the opposed surface. In this case, the lower end portion (hot water supply port 13) of the nozzle 14 comes into contact with the upper surface of the lid portion 45A. Preventing this is one of the effects of forming the recess 242.

  Moreover, the recessed part 242 is formed in a mortar shape, and the opening of the recessed part 242 and the opening of the hole part 451 are set to the same or substantially the same size. Also, the hole 451 is provided with an annular protrusion 451a. As can be seen from FIG. 13, when the milk preparation pot 4A fitted with the lid 45A is attached to the apparatus main body 2A, the hole 451 protrudes. The part 451a contacts the lower surface of the restricting part 24. That is, the recess 242 and the hole 451 are connected (joined).

  Therefore, even if the liquid splatters laterally from the hot water supply port 13, the liquid hits the concave portion 242, and the liquid droplet adhering to the concave portion 242 moves downward due to the mortar-like inclination and finally passes through the hole portion 451. It is injected into the milk preparation pot 4A. Further, the liquid does not enter the inside of the apparatus main body 2A. Further, liquid does not spill on the upper surface of the lid 45A. Thus, even if the liquid scatters from the hot water supply port 13 in the lateral direction due to the various features described above, the liquid does not easily adhere to the surroundings.

  Furthermore, in the present embodiment, one hole 33 is formed on the lower surface (opposing surface) of the restricting portion 24 so that a part thereof is recessed upward, and an opening 34 a is formed by the hole 33. The hole 33 has a shape that is long in the direction of the air path, in other words, has a groove shape. When the shape of the air flow passage 34 is an annular shape as in the present embodiment, the hole portion 33 has a long arc shape corresponding thereto. Since the hole 33 is open on the lower side by the opening 34a, it does not function as the air flow path 34 by itself, but the lid portion with the milk adjustment pot 4A attached to the mounting surface 211 of the apparatus main body 2A. When the opening 34a is covered by the upper surface of 45A, the portion surrounded by the upper surface of the hole 33 and the lid 45A becomes a substantially hollow tubular shape (duct shape), and functions as the air flow path 34.

  As another embodiment, a duct functioning alone as the air flow path 34 may be provided on the lower surface (opposing surface) of the restricting portion 24. However, in that case, it becomes difficult for the user to wipe off dirt adhering to the inside of the duct of the air flow path 34. On the other hand, in this embodiment, since the lower side of the hole 33 is opened by the opening 34a in a state where the milk preparation pot 4A is detached from the apparatus main body 2A, the user can pass through the opening 34a to the inside of the air flow path 34. Dirt adhered to the surface can be easily wiped off. Furthermore, in this embodiment, since one long hole 33 is formed, the hole 33 can be made relatively large. Therefore, the user can wipe off the dirt attached to the air flow path 34 from the hole 33 even more easily. That is, the inside of the air flow path 34 can be easily cleaned.

  Further, a guide portion 34h for guiding the main air flow AF1 generated when the fan 32 is operating into the lower milk adjustment pot 4A is provided inside the air flow passage 34.

  As shown in FIG. 14, the guide portion 34 h has an inverted triangular shape in the longitudinal section along the air flow path 34 and protrudes downward from the upper surface of the air flow path 34. Therefore, the guide portion 34 h has an inclined surface (first inclined surface) 340 that is inclined downward as it goes from the upstream side to the downstream side on the upstream side of the air flow path 34. Further, the guide portion 34 h has an inclined surface (second inclined surface) 342 that is inclined upward as it goes from the upstream side to the downstream side on the downstream side of the air flow path 34. Further, a gap 344 for allowing the main airflow AF1 to pass is formed between the lower end of the guide portion 34h and the bottom of the air flow path 34.

  According to such a guide part 34h, it is possible to change the flow direction of the main airflow AF1 that attempts to flow in the airflow passage 34 in the horizontal direction. Specifically, when the main airflow AF1 flows downward along the first inclined surface 340, the flow direction of the main airflow AF1 is changed obliquely downward. Thereby, a part of the main airflow AF1 becomes a subairflow AF2, and is guided from the hole 452 (hole 452b) into the milk preparation pot 4A and enters the milk adjustment pot 4A.

  Then, the auxiliary air flow AF2 becomes a swirling flow in the milk preparation pot 4A, stirs the air in the milk preparation pot 4A, and rises while attracting hot air of the milk M, and again, the hole 452 ( From the holes 452c and 452d), the main air flow AF1 of the air flow path 34 is merged.

  Thus, by providing the guide part 34h in the ventilation flow path 34, the sub airflow AF2 branched from the main airflow AF1 can be actively guided to the milk adjustment pot 4A. Therefore, the milk M in the milk preparation pot 4A can be efficiently cooled.

  Further, the air flow component that has not become the sub air flow AF2 in the main air flow AF1 passes through the gap 344, passes through the guide portion 34h, and is guided along the second inclined surface 342 to the upper surface of the air flow path 34. Is done. At this time, the airflow component joins again with the auxiliary airflow AF2 that attracted the hot air of the milk M in a state where the flow velocity is maintained to some extent, and flows smoothly downstream.

  Thereby, discharge | emission of the secondary airflow AF2 which attracted the hot air of the milk M can be accelerated | stimulated. Further, it is difficult for air to stay below the guide portion 34h. Therefore, the occurrence of condensation can be suppressed in the vicinity of the second inclined surface 342. As a result, the cooling unit 30A (the air flow path 34) can be maintained as clean as possible.

  Further, the concave portion 35 described above is formed on the lower surface (opposing surface) of the restricting portion 24. The recess 35 is formed in a straight line with the hot water supply port 13 and the detection unit 241. This straight line extends in the front-rear direction with respect to the powder milk preparation device 1A (device main body 2A). The concave portion 35 is provided at a position facing the protruding portion 450c when the milk adjustment pot 4A to which the lid portion 45A is attached is attached at a correct position. Therefore, when the milk adjustment pot 4A to which the lid portion 45A is attached is attached at the correct position, the protrusion 450c engages with the recess 35. That is, the milk preparation pot 4A to which the lid portion 45A is attached is fixed (locked) to the apparatus main body 2A.

  In addition, if the detection part similar to the detection part 241 is provided in the concave part 35 so as to detect that the protruding part 450c is engaged with the concave part 35, the milk adjustment pot 4A to which the lid part 45A is attached is provided. It is possible to detect that the main body 2A has been moved to a fixed position.

  When the user attaches the milk adjustment pot 4A to the mounting surface 211 of the apparatus main body 2A, first, the user grasps the handle 44 of the milk adjustment pot 4A and directs the spout 43 toward the apparatus main body 2A. The pot 4 </ b> A is moved from the front of the apparatus main body 2 </ b> A toward the placement unit 21 and the regulation unit 24. When the milk adjustment pot 4 </ b> A slides on the placement surface 211, the end portion 414 a of the protruding portion 414 is engaged with the tip end portion 212 a of the guide 212. At this time, the contact pin 241a is brought into contact with the tip of the guide groove 450d. When the milk adjustment pot 4A further slides on the placement surface 211, the protruding portion 414 is fitted with the guide 212, and the milk adjustment pot 4A moves on the placement surface 211 in the longitudinal direction of the guide 212 (long axis). Direction). Further, by moving the milk adjustment pot 4A, the contact pin 241a slides relatively along the guide groove 450d.

  Then, the milk preparation pot 4A stops when the tip 212a of the guide 212 contacts the base 414b of the protrusion 414, and the installation (installation) of the milk adjustment pot 4A to the apparatus main body 2A is completed. Further, the milk adjustment pot 4A gradually moves not only in the rear of the apparatus main body 2A but also in the upper part in the latter half of the operation of attaching the milk adjustment pot 4A to the apparatus main body 2A by the ribs 415 contacting the guide 212. Moved. Therefore, as shown in FIG. 13, the upper surface of the lid portion 45A gradually approaches the lower surface of the restricting portion 24, and when the attachment is completed, a part of the upper surface of the lid portion 45A comes into contact with the lower surface of the restricting portion 24.

  Further, when the attachment of the milk preparation pot 4A to the fixed position of the apparatus main body 2A is completed, the protrusion 450c provided on the lid 45A is engaged with the recess 35. As described above, since the projecting portion 450c has the inclined surface 4500, when the user slides the milk adjustment pot 4A on the placement surface 211, the inclined surface 4500 does not have to be pushed down by the user. Hitting the lower corner and lower surface of the restricting portion 24, the extending portion 450b is pushed down, and then the extending portion 450b is returned to its original state so as to engage with the recess 35.

  As described above, in the powdered milk preparation device 1A, in the milk preparation pot 4 placed on the placement portion 21 of the device body 2A, the powdered milk PM previously set inside and boiled for milk production are prepared. Milk M is produced by preparing and mixing the liquid L. As described above, the recess 242 is provided around the hot water inlet 13, and the protrusion 451 a of the hole 451 provided in the lid 45 </ b> A contacts (contacts) the lower surface of the restricting portion 24. Even if the liquid splashes laterally from 13, the liquid hits the recess 242 and is injected into the milk preparation pot 4 </ b> A through the hole 451. Further, the liquid does not enter the inside of the apparatus main body 2A.

  As described above, when the milk M is cooled, the main air flow AF1 generated when the fan 32 is operated is guided into the milk adjustment pot 4A, thereby adjusting the air above the lid 45A. The air is exchanged with the air inside the milk pot 4A. As described above, since the lid portion 45A has the substantially annular protruding portion 450f protruding upward at the outer peripheral portion of the main body portion 450, the upper surface of the main body portion 450 is the outer peripheral portion (edge portion). In almost the whole, it contacts (abuts) the lower surface of the restricting portion 24. Accordingly, since air leakage can be reduced as much as possible, the sealing performance (airtightness) between the apparatus main body 2A and the milk preparation pot 4A can be improved. Therefore, the exchange of air can be performed efficiently.

  FIG. 16 is a schematic diagram showing an outline of the powdered milk preparation device 1A according to the present embodiment. The schematic diagram shown in FIG. 16 is basically matched to the arrangement of components in the powdered milk preparation apparatus 1A shown in FIG. 1, and is symmetrical to the schematic diagram of FIG. The schematic diagram of FIG. 2 for explaining the operation and the like of the powdered milk preparation device 1A is symmetric with respect to FIG. 1, but even if it is symmetric, the operation of each component is the same. Further, in the first and second embodiments, if the positional relationship between the placement unit 21 and the milk preparation pot 4 (4A) is correct and the guide 212 protruding upward with respect to the placement surface 211 is provided. In order to achieve the effects of the invention corresponding to Embodiments 1 and 2, the perspective view showing the appearance shown in FIG. 1 and the schematic view shown in FIG. It will never be.

  In the case of producing milk M, the operation of each component of the powdered milk preparation device 1A shown in FIG. 16 is the same as that described in the first embodiment, and a duplicate description is omitted. However, as shown in FIG. 16, the downstream outlet 34c of the cooling unit 30A is provided on the back surface of the apparatus main body 2A. Further, as described above, the operation panel 6 is provided on the upper portion of the apparatus main body 2A (the restricting portion 24).

  17 shows the configuration of the milk preparation pot 4A and the cooling unit 30A in the state shown in FIG. 16, (a) of FIG. 17 is a perspective view, and (b) of FIG. 17 is (a) of FIG. It is an arrow directional cross-sectional view in the BB line of FIG. 17, (c) of FIG. 17 is an arrow directional cross-sectional view in the CC line of (a) of FIG.

  Note that (a) to (c) in FIG. 17 are also symmetrical with (a) to (c) in FIG. This is because (a) to (c) of FIG. 5 are described based on FIG. As described above, the feasibility of the invention corresponding to the first embodiment and the second embodiment is not impaired.

  As shown to (a)-(c) of FIG. 17, the hole part 33 is provided so that it may overlap with the three hole parts 452b, 452c, 452d. Further, as described above, the main airflow AF1 is a swirling airflow along the outer peripheral inner wall 34f of the air flow path 34, and flows in the horizontal direction from the upstream side inlet 34b to the downstream side outlet 34c. That is, the main airflow AF1 flows along the upper surface of the milk preparation pot 4A (strictly, inside the edge of the opening portion 42 of the milk adjustment pot 4A). Therefore, in a state where the milk preparation pot 4A with the lid 45A attached is attached to the placement portion 21 (fixed position), the four holes 452 are formed along the path of the main airflow AF1. Each hole 452 has a shape that is long in the direction of the main airflow AF1.

  However, in the present embodiment, as shown in FIGS. 17B and 17C, the hole 33 is located at the position corresponding to the hole 452a on the most upstream side of the main airflow AF1 on the lower surface of the restricting portion 24. Is not formed. This is because the air pressure entering the milk preparation pot 4A is narrowed to increase the wind pressure, and the air outlet exiting the milk preparation pot 4A is wider than the air inlet so that warm air is discharged as soon as possible. This is to improve the cooling efficiency. For this reason, the hole 452a may not be provided. In the present embodiment, in consideration of the beauty of appearance (aesthetic appearance), by forming four holes 452 on the left and right sides of the hole 451, the extending part 450b and the guide groove 450d in the lid part 45A, The lid 45A is formed in a symmetrical shape. That is, the lid 45A is axisymmetric about a straight line passing through the center of the hole 451, the center of the extending portion 450b, and the center of the guide groove 450d.
