[Industrial applications]

 The present invention relates to a water heating device, and is suitable for use in, for example, a water heating device that heats hot water for milk preparation.

[0002]

[Prior art]

 Conventionally, the temperature of hot water when preparing powdered milk for infants, that is, the optimum temperature for preparing milk, is said to be about 40 to 60 degrees Celsius. This takes into account the temperature of breast milk at about 40 degrees and the temperature at which the destruction of immune substances and vitamins at about 60 degrees begins.

In order to obtain this hot water, the water is not warmed from the beginning to a suitable temperature for milk preparation, but is used by cooling the boiled water once sterilized to a suitable temperature for milk preparation. . For this reason, conventionally, after putting water in a kettle and boiling it, the kettle is naturally cooled or tap water is used.

[0004]

[Problems to be solved by the device]

 However, in such a method of naturally cooling the boiling water in a kettle or cooling it with tap water, in addition to the time and labor involved, even if the milk is once cooled to a suitable temperature for milking, There is a problem that it is difficult to maintain this temperature.

In order to solve such a problem, for example, one having a heat-retaining bottle structure, which is configured to cool boiled hot water to a suitable temperature for milking for a certain period of time and maintain it, and an electric pot structure In some cases, water is once boiled to keep the milk at an appropriate temperature for milk preparation. However, in each case, there is a problem that it takes a long time to obtain hot water with a suitable temperature for milk preparation because the water is once boiled and cooled, which is still insufficient in terms of usability. Further, when the device is configured as a device for preparing milk, for example, it is desired that the device can be used as cleanly as possible. Furthermore, when preparing milk, the baby bottle had to be steam sterilized by a steamer or the like prepared separately.

In view of the above points, the present invention can remarkably improve the usability for the user, cool the hot water once boiled in a short time to a predetermined temperature to keep it warm, and use the device cleanly. It is an object of the present invention to provide a water heating device having a function of cleanly using a baby bottle and the like.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Since the embodiments described below are preferred specific examples of the present invention, various technically preferable limitations are attached. However, the scope of the present invention limits the present invention particularly in the following description. Unless otherwise stated, the present invention is not limited to these modes.

In FIG. 1, reference numeral 1 generally shows a mechanism of a water heater according to the present invention. The water heating device 1 is connected to, for example, a water tank 2 in which water for milk preparation is stored and a hole provided in the bottom surface of the water tank 2 and provided with a check valve, and is composed of, for example, a ceramic heater. It is mainly composed of a pipe 4 which is drawn into the heating unit 3 to boil water and a server 5 which receives hot water ejected from the pipe 4.

In the case of this water heating apparatus 1, the pipe 4 is routed to the server 5 through the water tank 2, and the boiling water heated in the heating unit 3 is heated by the water temperature in the water tank 2 to obtain a suitable milk preparation temperature. It cools down to spout. The pipe 4 is preferably shaped so as to have a spiral shape 4A near the bottom surface in the water tank 2 so that the heat exchange efficiency during cooling can be improved.

Further, the server 5 is arranged such that the bottom surface thereof is separated from the heating portion 3 by a predetermined distance, whereby the hot water of a suitable temperature for the milk prepared from the pipe 4 is received and stored, and the heating is performed. The hot water stored by heating the portion 3 is kept at a suitable temperature for milk preparation, for example. Further, as will be described later with reference to FIG. 3, the server 5 is configured so as to also serve as, for example, a disinfection container in the present embodiment, and is sufficient for accommodating a baby bottle inside. It has a large size, and is provided with a slender support 6 that can be removably inserted near the inner bottom surface and a cap that can close the upper opening.

FIG. 2 specifically shows the external appearance of the water heater of FIG. 1, and parts corresponding to those of FIG. 1 are designated by the same reference numerals. In FIG. 2, a power switch 8A with a lamp and a boiling / disinfecting changeover switch 8B having a push switch are arranged on an operation panel 8 arranged at the bottom of the case 7, and the boiling for displaying an operation state is displayed. A heat retention lamp 8C and a disinfection lamp 8D are arranged.

In the case of this water heating device 1, a lid 9 is provided in a shape that covers the water tank 2 and the server 5, so that dust and the like can be prevented from entering the water tank 2.

When steam sterilization of a baby bottle or the like is performed on the server 5, as shown in FIG. 3, a slats-like support tool 6 is detachably inserted near the inner bottom surface and the opening thereof is opened. Is closed by a cap 11 instead of the lid 10 shown in FIG. Here, the cap 11 is preferably formed in a dome shape capable of closing the upper opening of the server 5. And, the above-mentioned drainboard-like support 6 preferably has a ring-shaped outer diameter slightly smaller than the inner diameter of the server 5, and is provided with a rim-shaped support portion and a leg portion that supports this rim-shaped support portion. Then, a small amount of water is stored in the server 5 so that the water surface thereof is located below the upper surface of the above-mentioned slatted support 6. As a result, when the server 5 is heated by the heating unit 3, the water contained therein boils and evaporates, and the water vapor causes the water to be placed on the support 6 inside the server 5. The placed baby bottle and the like can be steam sterilized.

Actually, in the case of the water heater 1, the water tank 2 is designed to be capable of containing about 700 cc, that is, about four times of water as a baby bottle, and this water is stored in the water tank. Due to the influence of the remaining amount in 2, the temperature is first cooled to around 35 degrees Celsius in about 5 to 6 minutes, and finally reaches a temperature of around 80 degrees Celsius and is stored in the server 5. Therefore, when the water in the water tank is completely depleted, the temperature is kept at about 50 degrees, which is the optimum temperature for milk preparation.

In order to control the temperature in this way, in the water heating device 1, for example, two types of thermostats (not shown) are arranged. The first thermostat is provided in the vicinity of the outlet of the heating pipe portion 4B of the pipe 4 arranged in the lower portion of the heating unit 3, and detects the temperature of the pipe portion 4B which rises when all the water is sent to detect the temperature. The heating section 3 is turned off at about 120 degrees, and the thermostat controls the heating section 3 to be turned on and off at about 120 degrees Celsius. A second thermostat (not shown) is provided in the vicinity of the outlet of the heating pipe portion 4B, so that the heating portion 3 is controlled to be turned on and off at a temperature of about 50 degrees Celsius.

These thermostats are appropriately switched by operating the changeover switch 8B of the operation panel 8. Thus, as will be described later, when steam sterilization, after putting a small amount of water in the server 5, the first thermostat works to control the heating unit 3 to boil the water in the server, Perform steam sterilization. Further, in this disinfection mode, heating by the heating unit 3 may be performed for a certain period of time by using a predetermined timer without using a thermostat. When the changeover switch 8B is operated to boil water and keep warm, when the hot water has been stored in the server 5, the temperature of the heating pipe portion 4B rises, and the first thermostat operates at around 120 degrees Celsius. It will be. This is switched to the control of the second thermostat by the relay, and the hot water in the server is kept warm by the heating section 3 at an appropriate temperature of about 50 degrees.

In the above-mentioned configuration, when hot water for milk preparation is prepared using the water heating device 1 of this embodiment, the support tool 6 is inserted into the server 5 as shown in FIG. Then, after pouring a small amount of water, the baby bottle 12 to be steam sterilized is placed on the support 6 in an inverted state. Here, the power switch 8A of the operation panel 8 is turned on, and the changeover switch 8B is operated so that the disinfection lamp 8D is turned on. As a result, when the heat of the heating unit 3 causes the water in the server 5 to boil by the heating unit 3, the vaporized water vapor circulates in the server 5, whereby the baby bottle 12 can be sterilized with steam. It will be.

Thereafter, as shown in FIG. 4 (A), for example, after transferring a predetermined amount of water to the server 5 to the water tank 2, the power switch 8A is turned on as shown in FIG. 4 (B). Then, the changeover switch 8B is operated to turn on the boiling / heat keeping lamp 8C. As a result, as shown in FIG. 4 (C), the water stored in the water tank 2 is gradually boiled in a relatively short period of time, and the water is cooled in the water tank 2 one by one, and the water is adjusted to a suitable temperature for preparing the server. Stored in 5.

As shown in FIG. 4 (D), the hot water of a suitable milk preparation temperature thus stored in the server 5 is transferred to the baby bottle 12 containing the powdered milk after being steam sterilized as described above. , Can be prepared immediately. When hot water for milk preparation is left over, the server 5 may be set in the water heating device 1 again. As a result, the hot water in the server 5 is kept at the optimum temperature for milk preparation by the heating unit 3, and it is possible to always obtain the optimum hot water for milk preparation.

In the above-mentioned embodiment, the water heating device according to the present invention is applied to the one for boiling hot water for preparing milk, but the present invention is not limited to this, and the one for boiling hot water to dissolve powdered juice for infants and toddlers is used. It is also suitable for wide application to various water heating devices such as boiling water for pouring tea such as gyokuro.

Further, in the above-described embodiment, the server 5 is configured so as to serve as a container for disinfection and a container for hot water. However, it goes without saying that these may be used in separate containers.
