DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warmer used for both a milk preparation pot and a baby bottle.

[0002]

2. Description of the Related Art Milk preparation for nursing infants is performed by heating and boiling drinking water up to 100 degrees Celsius to sterilize it, and then boiling the water to an appropriate temperature of about 50 degrees, which is the optimum temperature of the beverage. Cool the water until it becomes hot water, transfer the hot water at the appropriate temperature for the preparation to a baby bottle about half of the target amount, put a predetermined amount of powdered milk into the baby bottle, and then put the mouthpiece and cap on the baby bottle. Set and shake the baby bottle, dissolve the powdered milk in the hot water, pour hot water to the target amount after all of the powdered milk is melted, shake the bottle lightly again to finish. As described above, the preparation of milk requires a great deal of time and effort for parents having infants, which is a great burden. Therefore, it is very convenient if hot water having an appropriate temperature for preparing the milk is always at hand to reduce the burden. Conventionally, several products of this kind have been developed, and among them, those products which are considered to be convenient are roughly classified into two types. One was a warmer with a boiling function for a milking pot, and the other was a warmer for a baby bottle.

As shown in a perspective view in FIG. 7, the former warmer with a boiling function for a milking pot includes a warmer 1 'with a boiling function for mounting a milking pot, a lid 21, a handle 22, and a glass container. The glass container main body 23 (a water amount display scale 24 is marked on the glass container body 23 so that the amount of water in the glass container body 23 can be recognized). The milk preparation pot 2 is an independent container by itself, and is used by removing it from a warmer with a boiling function when putting drinking water into it or pouring it into a baby bottle. It can also be used for applications. The bottom part of the milking pot 2 has the same shape and the same area as the heating upper surface of the insulated warmer 1 'with the boiling function and is in contact with each other without any gap, so that the heat from the insulated warmer 1' with low loss is reduced. To the milking pot 2. On the other hand, the warmer 1 'with a boiling function is of an electric heating type, and has a function of taking electricity from the power cord 11 and heating and boiling water to 100 degrees Celsius by a built-in high-power electric heater. After boiling the water, change the value of the electric heater by the temperature control knob 18 to 50.
The hot water temperature is maintained at a certain temperature between about 100 degrees and 100 degrees. A power indicator 13 indicating that electric heating and heat retention are being performed is provided near the temperature control knob 18.

[0004] This warmer 1 'with a boiling function for a milking pot
First, put a predetermined amount of drinking water in the milking pot 2 and place it on the warmer 1 'with a boiling function.
8 is adjusted to the boiling temperature, and the drinking water is first heated to boiling water by electric heating. Once the drinking water has boiled to 100 degrees, if the adjusting knob 18 is adjusted to the desired heat retaining temperature, after a predetermined time, the desired warming temperature of the desired warming temperature can be obtained. is there. Therefore, the use of the incubator 1 'with a boiling function can always provide a suitable temperature for milk preparation, so that the above milk preparation work can be speeded up and the milk preparation can be easily completed. The hot water of the milk preparation pot 2 is around 50 degrees, and gyokuro, sencha, matcha and the like are preferably around 50 degrees, so that it can be used not only for milk preparation but also for other purposes, which is convenient.

[0005] However, since the insulated warmer 1 'with a boiling function is exclusively intended to be boiled by electric heating, the insulated warmer 1' with a boiling function is provided with drinking water in a milk preparation pot 2 '.
The biggest drawback is that it takes too long to get the hot water of the right temperature when you put it in. Taking a commercially available product as an example, this warmer with a boiling function 1 '
It is 215 W at 0 V, about 1 hour to boil 300 cc of water, about 75 minutes with 500 cc of water, and about 800 cc of hot water required by infants a day.
0 cc of water requires about 2 hours or more. In addition, since all the heating is performed by electric heating, there is a disadvantage that power consumption is too high compared with gas heating and it is uneconomical. In order to obtain hot water of the appropriate temperature for the preparation, this boiling water is further cooled naturally to hot water of the proper temperature for the preparation.
It took about 4 hours, and it took about 4 hours in total to obtain hot water of the appropriate temperature from the cold drinking water. Further, since the warmer 1 'with the boiling function has a high-output electric heater required for the boiling function and a boiling control circuit, the purchase price is high, the circuit is complicated, and the circuit is easily broken.

[0006] Furthermore, this warmer 1 'with a boiling function is:
It was quite inconvenient when used in the bed at night. In other words, most of the milk preparation work that is performed when an infant crys on a night hunger is performed while the parent is on the bed. This is especially true on cold winter nights. The operation of holding the milk preparation pot containing 800 cc of hot water with one hand while staying on the bed causes a considerable burden on the arm because the arm is in a cantilevered state. Especially for mothers who are tired during daytime childcare, sleepy at night,
This task of holding a milk preparation pot with 800 cc of hot water in one hand while being rushed by the baby's cry was very harsh, and therefore this milk preparation pot was unsuitable for use at night.

[0007] As a convenient and inexpensive milk preparation at night to solve the above-mentioned drawbacks, another product has hitherto been put on the market. It is the above-mentioned warmer for baby bottles. As shown in a perspective view in FIG. 8, this is a low-power electric heater (commercially available
5W) It is composed of a built-in warmer 1 and a fully closed cover 39 placed on the warmer 1, and the warmer 1 has a warming recess 19 into which the baby bottle 9 is inserted and supported. It is provided in the place. The warmer 1 is provided with a power cord 11 and a power indicator 13 for indicating that electric heat is being maintained.

[0008] The method of using the warming device 1 for a baby bottle is as follows. First, boiling water separately boiled with gas or the like is put in the baby bottle 9 in an amount required for milk preparation, and is set on the heat retaining recess 19, and the cover is fully closed. By closing the power supply 39 and plugging the power cord 11 into a 100 V outlet, it is possible to obtain hot water having a desired temperature suitable for preparing the milk after 3 hours. In this way, if the warmer 1 with the baby bottle 9 is placed at the bedside at night, when the baby crying on an empty stomach, the parent opens the cover 39, removes the baby bottle 9 from the warmer 1, and puts the powdered milk therein. Since it is completed simply by shaking in a bowl, it is convenient without having to hold the heavy milk preparation pot as described above with one hand.

[0009] However, since the baby bottle warmer 1 has a warming cover and the cover is the fully closed cover 39, it takes a long time of three hours for the boiling water to cool down to the hot water suitable for the preparation of the milk. There was a drawback to do. In addition, when a new baby bottle with boiling water is set up next to a baby bottle that is already kept in hot water of the appropriate temperature, the heat dissipated from the new baby bottle with hot water will be dissipated in this fully closed cover. The drawback is that the baby bottles that are already kept at the temperature for preparing the milk become hot, and when removing one of a plurality of baby bottles that are already kept in hot water that is suitable for preparing the milk, this cover is completely closed. The warm air inside the cover that was in equilibrium was dissipated because it had to be opened, and when the fully closed cover was closed again, the warm air in the fully closed cover replaced the cold ambient temperature. Therefore, there was a disadvantage that the temperature of the remaining baby bottle was lowered.

[0010] In addition, this warming device for baby bottles, on the contrary,
It was inconvenient in that it did not have the advantages of the incubator with a boiling function. That is, this warming device for baby bottles cannot be used for purposes other than baby bottles. In other words, a pot shaped like a milking pot has the convenience that it can be used not only for milk preparation but also for other uses that require hot water at around 50 degrees, such as gyokuro, sencha, matcha, etc. Does not have this convenience. Another drawback is that it is not possible to employ a rapid milk preparation procedure in which the powdered milk is first dissolved in approximately half the target amount of hot water and then the remaining hot water is added to the baby bottle, which is the procedure of the milk preparation operation described above. In other words, in this method of using a bottle warmer, the amount of hot water necessary for formula preparation is already added to the bottle from the beginning, so even if the bottle is shaken to dissolve the powdered milk, the hot water in the bottle can be removed. The movement is slow and the milk powder is difficult to mix. Therefore, it was necessary to shake the baby bottle for a long time until all the powdered milk was dissolved. Therefore, at night, this baby bottle warmer, which is convenient for preparing milk from the bed,
It is inconvenient for preparing milk during the daytime and it is much more efficient to use a milking pot.

[0011]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the disadvantages of both the above-mentioned warmer with a boiling function and the warmer for baby bottles (both of which are drinking water → boiling → radiation →
It took more than 3 hours to reach the milk preparation temperature. ) And to obtain a warmer that can use both the function of the warmer with the boiling function and the function of the warmer for baby bottles.

[0012]

Means for Solving the Problems An electric heater for controlling the temperature of the milk to be controlled by an electric heater, a heat conducting plate and a mounting plate disposed immediately above the electric heater and in close proximity to the electric heater are provided. In order to selectively place the milk pot and the opening cover for holding a baby bottle, a peripheral ridge formed from a part of the peripheral wall of the heat insulator is provided around the heat conduction plate and the mounting plate. Things. The opening cover for holding a baby bottle has an upper surface at a size and height at which a part of the baby bottle is exposed when the baby bottle is placed on a warmer. Further, the electric heating device turns on and off the electric heater only so that the boiling water placed in the milking pot or the baby bottle placed on the placing plate is maintained at an appropriate temperature in a steady state. A control circuit configured by a thermostat for controlling, wherein the control circuit is configured such that when there is a difference in ambient temperature, the boiling water contained in the milk-supplying pot or the baby bottle is in a steady state at a suitable temperature for preparing the milk. And a changeover switch for connecting either thermo-high or thermo-low in series with the electric heater so that the electric heater is held.

[0013] The thing to be placed on the warmer is preferably a milking pot having a container body, a handle and a lid. In particular, the bottom of the container body has a peripheral ridge formed on the warmer. , And a lid is formed on the rear side of the lid at a portion where the lid comes into contact with the container main body for air circulation.

Alternatively, the one to be placed on the warmer is an inverted-concave opening cover in which an upper surface and a peripheral portion are covered, a lower surface is opened, and a large space is formed therein. The upper surface of the cover is provided with at least one opening having a size into which the baby bottle is inserted, and the height of the peripheral portion is formed lower than the height of the baby bottle.

[0015]

As described above, this warming device according to the present invention is exclusively used for keeping warm, and the heating is left to another gas heating having a high calorie and a low cost, so that cold drinking water is turned into hot water of a suitable temperature for preparing milk. Time is significantly reduced. And since this warmer can be used for both the warming pot and the baby bottle, it is possible to select the container which is more convenient for day and night. In addition, since a switch for switching the control circuit is provided, even when there is a difference in the ambient temperature, the boiling water contained in the milking pot or the feeding bottle is maintained in a steady state at an appropriate temperature for the milking, and further, the warmer Since the peripheral raised portion is formed around the periphery of the container, a milking pot and a baby bottle can be reliably placed. In addition, the milk preparation pot placed on the warmer is particularly sized so that the bottom of the container body fits inside the surrounding ridge formed on the warmer, so that the heat is efficiently kept, and Because the lid is formed on the back side of the lid with a protruding portion for air circulation at a portion where the lid comes into contact with the container main body, the cooling time until boiling water becomes hot water of a suitable temperature for preparation is greatly reduced. . Further, the cover to be placed on the warmer is an inverted-concave opening cover in which the upper surface and the peripheral portion are covered, the lower surface is open, and a large space is formed inside, and the upper surface of the opening cover The part is provided with a plurality of openings of a size into which the baby bottle is inserted, and the height of the peripheral portion is formed to be lower than the height of the baby bottle, so that the baby bottle is inserted into this opening. Because the upper part of the baby bottle is exposed from the opening when it is set up, the time required for the boiling water to radiate heat and reach the milk preparation temperature is greatly reduced, and also when one of a plurality of baby bottles is taken in and out. Since it is not necessary to remove the cover as in the related art, the heat retention state in the cover does not change. Also, even if a boiling water bottle is placed next to the bottle, most of the heat is radiated from the part exposed through the opening of the bottle, so there is no heat and the temperature of other bottles is affected. I do not give.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a warmer 1 for a milking pot and a baby bottle according to an embodiment of the present invention, which incorporates a low-output electric heater only for keeping warm and a control circuit therefor. Power cord 11 for that

A high switching lever 12, a power indicator light 13 indicating that the apparatus is in a warm state, and a heat conductive plate 14 serving as a mounting plate for mounting a milking pot or a baby bottle thereon. In addition, a peripheral raised portion 15 is formed to securely hold a milk preparation pot and a baby bottle placed thereon. Focusing on the fact that 800 cc of water can be boiled in only 5 minutes by gas heating, compared to the case of the above-mentioned incubator with a boiling function that required 2 hours to boil 800 cc of water. The heating and boiling of water depends on a fast and cheap gas to be heated, and it is a feature of the present invention that this warmer 1 is exclusively used for keeping warm.

FIG. 5 shows a circuit diagram of an electric heating circuit 4 composed of an electric heater and a control circuit built in the heat retaining device 1 exclusively used for keeping heat. The electric heater 45 used here is only for keeping heat, and is 85 V at 100 V.
An electric heater with a low output of W may be used. Therefore, the control circuit is simple and the thermostat 4 is set at a high temperature for winter.
41 and a thermostat 442 with a low temperature setting for summer are prepared and switched by a changeover switch 43. Further, a thermal fuse 42 is provided between the power input unit 41 and the heater 45 to prevent overheating due to overcurrent at the time of an accident. Further, there is the above-mentioned power indicator light 13, which is turned on even if the changeover switch is on the thermostat 441 side or the thermostat 442 side, and is turned off only when the changeover switch is on the off side. Installed. As described above, since the electric heating circuit 4 of the present invention does not aim at heating and boiling the drinking water, the circuit is very simple, so that the price is low, light, and hard to break down.

FIG. 2 shows a milk preparation pot 2 according to the present invention, which is mounted on a heat-conducting plate 14 on the heat retaining plate 1 of FIG. 1 which is an embodiment of the present invention. The milk preparation pot 2 includes a lid 21, a handle 22, and a container body 23 made of a glass container. The container body 23 made of a glass container stores the amount of hot water stored in the container body. The indicated water volume display scale 24 is marked, and the spout 2 for further pouring hot water.
5 are formed. The lid 21 is pivotally supported at the upper part of the handle 22 for convenient handling. Although the lid 21 is large enough to cover the upper opening of the container body 23, a protrusion 211 is formed on the lid 21 in order to quickly dissipate the heat of the hot water put therein to the outside. Further, the bottom of the container body 23 is formed to have a size that fits inside the peripheral ridge 15 formed in the heat retaining device of FIG. The height and shape of the container are such that the heat energy received from the heat conducting plate and the mounting plate 14 and the heat energy dissipated from the container quickly reach the temperature range suitable for preparing the milk, and this temperature is maintained with high efficiency for a long time. It is designed to have a large bottom area and a low height.

FIG. 4A is a longitudinal sectional view showing a state where the milk preparation pot 2 shown in FIG. 2 is placed on the warmer 1 shown in FIG.
From the figure, the bottom of the milk preparation pot 2 of FIG.
It can be understood that there is no gap with poor heat transfer efficiency inside the surrounding raised portion 15 formed in the above. Also, lid 2
The projecting portion 211 formed on the back side of the container 1 serves to lift the lid 21 from the upper opening of the container body 23 to secure a space for air to flow, so that boiling water is put into the milk preparation pot 2. In this case, it can be understood that the heat of the boiling water easily escapes to the outside of the milk preparation pot 2. Further, the electric heater 4
5 so that the heat supplied to the milk preparation pot 2 from FIG. 5 and the heat dissipated from the whole milk preparation pot 2 are quickly balanced and the balance is efficiently maintained for a long period of time. It can be understood that the bottom area is relatively large and the height is relatively low as compared with.

FIG. 3 shows the opening cover 3 according to the present invention which is mounted on the heat-conducting plate 14 of the heat retaining device 1 of FIG. 1 which is an embodiment of the present invention. The opening cover 3 is formed of plastic, has an inverted concave shape in which an upper surface and a peripheral portion are covered, a lower surface is opened, and a large space is formed inside. A plurality of openings 31 (three in FIG. 3 which is an embodiment) having a size into which a baby bottle is inserted are provided on the upper surface, and the height H of the peripheral portion is set.
Are formed lower than the height of the baby bottle. An engaging portion 32 that curves outward is formed at a lower portion of the opening cover 3. The bending engaging portion 32 allows the opening cover 3 to be placed on the warmer 1 of FIG. 1. When this is done, it conforms to the curvature of the peripheral ridge 15 formed on the incubator 1. Thereby, the warmer 1 of the opening cover 3
Placement on the top becomes stable.

FIG. 4B-1 shows FIG. 3 on the warmer 1 of FIG.
A state in which the opening cover 3 is mounted is shown in a longitudinal sectional view. 3 that the curved engagement portion 32 of the opening cover 3 of FIG. 3 is placed on the curvature of the peripheral ridge 15 formed on the heat retaining device 1 of FIG. 1 without any gap, thereby improving heat transfer efficiency and improving the heat transfer efficiency. Is stably mounted on the incubator 1.

FIG. 4B-2 shows a state where the baby bottle 9 is inserted into the opening 31 in the state of FIG. 4B-1.
As can be seen from the figure, since the height H of the opening cover 3 is lower than the height of the baby bottle 9, it can be seen that the upper part of the baby bottle 9 is exposed above the opening cover 3. Since the upper part of the baby bottle is exposed from the opening when the baby bottle is set in this opening in this manner, when taking in and out of the baby bottle, it is possible to remove the baby bottle from the opening without removing the cover as shown in FIG. Not only can the exposed baby bottle portion be picked up and easily taken out, but the heat retention efficiency in the cover does not change, so the heat retention efficiency is good. Further, when one of the plurality of baby bottles is taken out, the cover does not need to be similarly removed, so that the heat retaining state in the cover does not change.

Furthermore, the effect of making the height H of the opening cover 3 lower than the height of the baby bottle 9 is more prominent from this exposed portion of the baby bottle 9 when a baby bottle containing boiling water is set up here. Since the heat is radiated, the time required for the milk to reach a suitable temperature of about 50 degrees is greatly reduced.
If the heights are the same, as shown in FIG.
6 and it takes three hours for natural cooling as shown in the graph of FIG. 6, which is not suitable for the purpose of the present invention. Conversely, if the height H of the opening cover 3 is set too low, although it cools quickly, it exceeds the optimum temperature for preparing the milk and equilibrates near room temperature as shown in the graph of FIG.
A high-output heater is required to maintain the milk at a suitable temperature, which is not suitable for the purpose of the present invention. Therefore, how to select the height H of the opening cover 3 is important for realizing the object of the present invention.

FIG. 9 shows the height H / of the opening cover 3.
The horizontal axis represents the height of the baby bottle, the time T required for the boiling water to reach the milk preparation temperature of about 50 degrees (unit: minutes (indicated by a circle)) is the left vertical axis, and the milk preparation temperature of about 50 degrees. Is a graph of data collected on the right vertical axis of the electric power W (unit: watts (marked by x)) required to maintain. As shown in the figure, the range in which the time T required for the boiling water to reach the milk preparation temperature of about 50 degrees does not exceed 2 hours is the height H of the opening cover 3 / the height of the baby bottle 2/3 or less. It can be seen that it is. In addition, the range where the power required to maintain the milk preparation temperature of about 50 degrees does not exceed 100 W is such that the height H of the opening cover 3 / the height of the baby bottle is about 1 /.
It turns out that it is three or more. Therefore, considering both factors comprehensively, the practical range suitable for the purpose of the present invention is that, according to the above experiment, the height H of the peripheral portion is about 1/3 of the height of the baby bottle. It can be seen that they are formed within the range of 2/3. In addition, even if a baby bottle of boiling water is set up next to it, most of the heat is radiated from the part exposed from the opening of the baby bottle, so there is no heat and the temperature of other baby bottles Has no effect. In addition, when the baby bottles are all set up at the three openings and the temperature is in an equilibrium state, two of the baby bottles are removed and the temperature in the equilibrium state after 80 minutes is measured. It was minus 3 degrees Celsius. This indicates that the number of baby bottles set in the opening has almost no effect.

FIG. 6 shows the temporal change of the hot water temperature when the boiling water-containing milk preparation pot 2 is placed in the state of FIG. 4A, and the hot water when the boiling water-filled baby bottle is placed in the state of FIG. Temporal change of temperature, Temporal change of hot water temperature when boiling water-containing milk preparation pot 2 is left indoors, Temporal change of room temperature at that time, and the conventional insulated heater with a boiling function shown in FIG. 9 shows a temporal change of the hot water temperature and a temporal change of the hot water temperature in the case of the conventional baby bottle warmer of FIG. As can be seen, when the room temperature is constant, the milk-supplying pot of the present invention reaches the optimum temperature in 90 minutes.
It reaches the optimal temperature for formulating in 10 minutes. The milking pot of the present invention has a shape such that the milking pot of the present invention reaches a suitable temperature for milking faster than the conventional milking pot (the conventional milking pot of FIG. 7 is easily radiated). This is because the relative height is lower than the shape and a protruding portion formed on the back side of the lid is provided). Moreover, although it is not clear from this graph, since the conventional one shown in FIG. 7 is heated and boiled by electric heating, it takes a considerable amount of time to become boiling water in the first place (this invention requires 5 cc to boil 800 cc of water). Minutes, while the conventional one of FIG. 7 takes just over two hours.)

Next, the baby bottle of the present invention reaches a suitable temperature for preparing the milk in 90 minutes, while the conventional baby bottle has a temperature of 180 minutes.
Reach the optimal temperature in minutes. This is because, as described above, the shape of the cover is devised so that the baby bottle of the present invention reaches a suitable milk preparation temperature faster than the conventional milking pot. still,
In the milking pot of the present invention and the baby bottle of the present invention, the equilibrium temperature of the former is set only 5 degrees higher than the latter, when the hot water of the milking pot is poured into the baby bottle at about 5 degrees. This is because the temperature of the hot water drops.

[0027]

As described above, according to the present invention,
The time from cold drinking water to hot water of a suitable temperature for preparation can be greatly reduced as compared with the conventional one, and the cost can be reduced. In addition, since a switch for switching the control circuit is provided, even when there is a difference in the ambient temperature, the boiling water contained in the milking pot or the feeding bottle can be surely kept at a suitable temperature in a steady state in a steady state. The formation of the peripheral ridge around the container makes it possible to securely place the milk preparation pot and the baby bottle.

The milk-supplying pot placed on the warmer is so sized that the bottom of the container body fits inside the surrounding ridge formed on the warmer, so that the warming can be efficiently carried out. In addition, since the lid is formed on the back side of the lid with a protruding portion for air circulation at a portion where the lid comes into contact with the container main body, the cooling time until the boiling water becomes hot water of a suitable temperature for preparing the milk is conventionally used. Significantly shortened compared to milking pots.

Further, the cover of the present invention mounted on the warmer is provided with a plurality of openings large enough to insert baby bottles on the upper surface of the opening cover, and the height of the peripheral portion is increased. Because it was formed lower than the height of the baby bottle,
When a baby bottle is placed in this opening, the top of the baby bottle is exposed from the opening, and the time required for the boiling water to radiate heat and reach the milk preparation temperature is significantly reduced, and among the plurality of baby bottles, It is not necessary to remove the cover as in the related art even when removing and inserting one piece, so that not only is it convenient, but the heat retaining state inside the cover is slightly affected but does not change. Also, even if a boiling water bottle is placed next to the bottle, most of the heat is radiated from the part exposed through the opening of the bottle, so there is no heat and the temperature of other bottles is affected. I do not give.

In addition, both the conventional warmer with a boiling function for a milking pot and the warmer for a baby bottle have only a single function. How to use both a warmer with a function and an expensive warmer for a baby bottle, for example, using a warmer with a boiling function for a milking pot in the daytime and using a warmer for a baby bottle at night According to the present invention, the combined use of the warmer of FIG. 1 and the conventional warmer having a boiling function for a milking pot with the set of FIG. 2 and FIG. In addition to performing both functions as a warmer for water, it is possible to solve a disadvantage that is common to both conventional ones, that it takes too much time to obtain hot water of a suitable temperature for preparing milk from drinking water.
