The present invention relates to a thermos, and in more detail, in view of the relatively low bacterial incidence at low temperatures, usually in a refrigeration or freezing device by refrigeration or freezing the contents and then put in a thermos to cool, the reserved time The present invention relates to a reservation heating vacuum thermos, characterized in that to maintain the heating temperature after the contents are heated to a set temperature.

In general, thermos refers to a container made to keep contents (hot water, cold water, other drinks, etc.) at about the same temperature for a long time.

As such a conventional thermos bottle, the outer bottle 20a and the inner bottle 20b are joined together with the vacuum chamber 50 as shown in FIG. In addition, the inside of the inner bottle 20b is plated to prevent heat conduction by radiation.

The conventional thermos is vacuumed by removing the air in the middle of the double wall, and plating the inner wall of the double wall to prevent heat conduction and to prevent heat conduction by radiation. In other words, when the temperature of the extraterrestrial is high, it absorbs radiation from the extraterrestrial to reduce the absorption of heat, and when the temperature of the extraterrestrial is low, it reflects the radiation from the contents and sends it back to the inside. have.

In this way, since the heat is blocked from entering the outer space, the thermos can be used for the purpose of keeping warm or cold.

On the other hand, depending on the situation, it is often necessary to heat the contents stored in the freezer (for example, breast milk stored in the freezer). In this case, it is impossible to carry out the above-described thermos. It is proposed.

However, the proposed methods, such as supplying power to the heating element installed inside the inner bottle of the vacuum thermos bottle or removing and exposing the vacuum layer and the outer bottle to a part of the inner surface of the inner bottle, attaching the heating element, and the like. There is a problem that easily occurs and the intrinsic function of the thermos significantly lower the thermal barrier ability.

In addition, until now, only the function of heating only the lost temperature in order to maintain a constant temperature, there was a problem that is not suitable as a means for raising the cold content to a low temperature at low temperature where bacterial growth is suppressed.

Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to continuously cool the contents of the refrigerated or frozen state in which the occurrence of bacteria is minimized, and then heat the liquid to a temperature set at the reservation time for the fluid. It is to provide a pre-heated vacuum thermos that is effective in the supply of the contents.

An object of the present invention as described above, the outer container and the inner bottle is bonded to the thermal container with a vacuum chamber inside;

A connection pipe extending from the upper part to the lower part of the vacuum chamber and provided in close contact with the lower side in the inner bottle;

Heating means provided in the connecting pipe, located on the bottom side of the inner bottle; And

Electrically connected to the heating means, it is achieved by a pre-heated vacuum thermos, characterized in that consisting of a control device provided on the outer peripheral side of the outer bottle.

In addition, in the present invention, the control device includes a power supply unit for providing an external power source;

An input unit for setting a reservation time;

A control unit for setting a reservation time by setting a reservation time of the input unit, and determining whether or not a power supply is supplied to the heating unit by checking whether the reservation time is reached or under;

It may be configured to include a display unit for displaying the reservation time set value of the input unit and the operation state of the heating means.

Other objects, specific advantages and novel features of the invention will become more apparent from the following detailed description and the preferred embodiments described in connection with the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

2 is a view showing a vertical section of the pre-heated vacuum thermos according to an embodiment of the present invention, the present invention is a control device 60 provided on one side of the outer bottle (20a), the outer bottle (20a) and the inner bottle (20b) Installed in the vacuum chamber 30 between the upper and lower portions of the vacuum chamber 30 and provided in the connecting tube 21 and the connecting tube 21 installed in close contact with the lower side of the inner bottle 20b. It is characterized by including the heating means 70 located in the bottom face side of the inner bottle 20b.

The heating means 70 is installed in the connecting pipe 21 to increase the temperature of the contents 50 stored in the inner bottle 20b, and may be a PTC (Positive Temperature Coefficient). Apart from shown, it may be provided at any position in the connecting pipe 21.

5 is a vertical cross-sectional view of a pre-heated vacuum thermos according to another embodiment of the present invention, wherein a heating vessel 20c is added to the container 20 in one embodiment of the present invention.

In addition to the heating vessel 20c, the heating means 70 is provided in close contact with the outer bottom of the heating vessel 20c, and the outside of the heating vessel 20c and the inside of the vessel 20 are not in a vacuum state. Is different.

Hereinafter, a method of operating a preheated vacuum thermos consisting of the above configuration will be described.

First, in the present invention, the type of the contents 50 is not limited, but in order to explain the present invention, the contents 50 are limited to breast milk. Here, breast milk is always kept at a constant temperature, which is very fresh and can be stored for 6 months at room temperature, 24 hours in a refrigerator, and frozen for one month.

Therefore, the mother's milk is refrigerated or frozen below 4 ° C, which is difficult to inhabit bacteria, and then cooled in a thermos. Next, when the heated mother milk is heated to an input unit 10c of the controller 60 is set. For example, if the current time is 10 am and 2 hours later, the mother milk is to be heated to 25 ° C. The reservation time is set to 2 hours and the temperature is set to 25 ° C. through the input unit 10c. Then, after 2 hours, the control unit 11 supplies power to the heating means 70 by the value set from the input unit 10c, and the heating means 70 supplies power within a range not exceeding 25 ° C. Receive the supply, and if it exceeds, it maintains 25 ℃ while repeating the operation to cut off the power.

By using the pre-heated vacuum thermos according to the above, the contents of the refrigerated or frozen state that minimizes the occurrence of bacteria is continuously cooled and then heated to the temperature set at the time of reservation, which is effective in supplying fluid contents. This is useful when you want to receive breast milk for infants. In addition, with excellent hygiene and convenience, it is possible to efficiently manage the breast milk collected through the breast shrinker.

Although the invention has been described in connection with the preferred embodiments mentioned above, it will be readily apparent to those skilled in the art that various other modifications and variations can be made without departing from the spirit and scope of the invention. It is obvious that all modifications fall within the scope of the appended claims.
