Description

Portable Cooling and Cooling Cabinet {Portable Cooling / Heating Cabinet}

The present invention relates to a portable cold storage cabinet, and more particularly, to a portable cold storage cabinet that combines refrigeration and warming in an adiabatic space that is a portable transport space.

In general, a portable cold and hot refrigerator is produced by a combination of refrigeration or warming, typically an ice box as shown in FIG.

This is to provide a thermal insulation space on the enclosure, and to insulate the cooling pack or hot pack, which is responsible for cooling or heating, together with the storage items.

Portable cold and hot storage for this is a case filled with a heat insulating material is provided with a heat insulating body (1), which is divided into a housing body (2) and the opening and closing cover (3) is hinged to each other.

The opening and closing cover 3 is equipped with a handle (not shown) or a shoulder belt (not shown) for transporting when carrying, the opening and closing cover 3 and the main body 2 is fastened with a clamp (4) or the like.

The sealed inner space of the enclosure body and the opening / closing cover provides a thermal insulation space so that a sealing packing or a locking step or a groove part is formed at the boundary thereof, and a cooling pack or a hot pack inserted into the thermal insulation space is subjected to convection or predetermined heat conduction. This is to cool or warm the internal filling.

However, the conventional portable cold and hot store has a problem that can not be used at the same time refrigeration or heating.

That is, since only a cooling pack (not shown) or a hot pack (not shown) is selectively used in the insulation space provided by the insulation enclosure, it is not possible to perform cold and hot storage through the cooling pack and the hot pack at the same time.

This is particularly inconvenient in the food culture that uses rice as a staple, because rice and soup need to be transported in a warm state, and cold and cold can not be carried out simultaneously in a single space.

In addition, there is a problem in that the storage of cooling packs or hot packs, etc., is inconvenient, and the bulky cooling packs or hot packs are simply put together with the refrigerated article or the warmed article in the insulation space provided by the main body, so that the insulation as a clean space You will not be able to provide space.

In addition, the cooling pack or the hot pack may be arranged to be mounted at any portion, but in this case, there is a problem that sufficient cooling or heating cannot be performed by the biased arrangement.

The present invention has been made in order to improve the above problems, it is an object of the present invention to provide a portable cold and hot storage that combines the refrigeration and warming in a single insulation transport space.

The present invention for this purpose is to divide the insulation space provided by the portable insulation enclosure into a thermal insulation partition wall to provide two or more insulation spaces adjacent to it and to provide a portable cold and cold storage by providing a cooling means and heating means such as a cooling pack or hot pack. .

And, Figure 4 is a conceptual diagram showing a cold and hot refrigerator applied thermoelectric element as a cooling and heating means as another embodiment of a portable cold and hot refrigerator according to the present invention.

The present invention is provided with a movable or portable heat insulating housing made of a heat insulating material, the cooling means or heating means is provided in the heat insulating housing in a portable cold or cold storage that is carried out portable refrigeration or warming,

Insulating partition (10) made of a heat insulating material is formed so that refrigeration and warming is performed in one heat insulating body (1), two or more separate heat insulating spaces (12) and (14) are provided and the heat insulating spaces (12) (14). Portable cold and cold storage, characterized in that the cooling means and heating means is installed separately.

Here, as an embodiment, a seating groove 20 in which the cooling pack 16 or the hot pack 18 is seated is formed in the heat insulating spaces 12 and 14, and as the inner wall of the seating groove and the heat insulating space adjacent thereto. The thermal conductive panel 22 is characterized in that it is installed.

Here, in another embodiment, the thermal insulation partition wall 10 that distinguishes the refrigerator and the warmer is provided with a thermoelectric element 24 as a boundary wall, so that the cooling surface 26 and the heating surface 28 of the thermoelectric element 24 are respectively separated. It is characterized in that exposed to the heat insulating space (12) (14).

In this case, the power supply of the thermoelectric element 24 is characterized in that the cigar jack 36 is mediated so as to be applied from the vehicle, and the battery 34 is further mediated between the cigar jack and the thermoelectric element.

As described above, the present invention provides a portable cold storage cabinet that performs both refrigeration and warming in one heat insulation enclosure (1).

The present invention for this purpose is first divided into a heat insulating space provided by the heat insulating enclosure is divided into a heat insulating partition (10) adjacent to each other the heat insulating space (12, 14).

Here, the heat insulating spaces 12 and 14 provided by the heat insulating enclosure 1 refer to a space separated from the outside formed by the body 2 and the cover 3, and filled in the case and the inside as described above. Provided insulation.

The insulating partition wall is also made of a heat insulating material is filled in the case forming it, by the insulating partition wall 10 is divided the insulating space.

Cooling means and heating means are built in the divided thermal insulation spaces 12 and 14, respectively, and a seating groove 20 is provided for accommodating them.

The storage of the cooling and heating means in the seating groove 20 exposes only the cooling surface or the heating surface to the adiabatic space to provide an organized storage space and further facilitates the storage and placement of the storage article.

When the cooling pack 16 and the hot pack 18 are inserted, the cooling pack 16 and the hot pack 18 are preferably disposed at the bottom, and the hot pack 18 may provide a separate heating means as heat transfer means.

For example, a portable heating device (Application No. 20-2004-0027499) can be applied as a hot pack, which is provided with a case body made of a portable unit independently, and the case body is in contact with a heating wire to release heat to the outside. In this case, a heating device including the heating wire and a battery for supplying power to the heating wire and a control unit for controlling the heating wire is built into the case body through a heat insulating material, thereby forming an independent portable heating means.

When such a portable heating means is applied to a warmer in a portable cold and hot refrigerator of the present invention, the warming can be performed more conveniently by the user.

In addition, in order to further assist the heat transfer of the cooling means and the heating means, each of the heat insulating spaces 12 and 14 is equipped with heat conducting means surrounding the inside thereof.

The heat conductive panel 22, which is a metal thin film having high thermal conductivity, is installed on the inner wall of the heat insulating spaces 12 and 14, respectively, and is installed up to the seating groove 20 in order to contact the cooling means or the heating means.

Therefore, when the cooling pack 16 or the hot pack 18 housed in the seating groove 20 is in thermal contact with the heat conduction panel 22, the heat is transferred to the inner wall, and the cooling pack 16 is cooled to the heat insulating space exposed therein. The heat is assisted, and the holding groove 20 is formed in the gripping groove 30 to facilitate the departure of the cooling pack 16 or the hot pack 18.

On the other hand, the cooling and heating means can be applied to the thermoelectric element 24, in this case, both the cooling surface and the heat dissipation surface of the thermoelectric element can be used.

That is, the thermoelectric module 24 is formed in the form of a module in which n and p type thermocouples 32 are electrically connected in series and thermally parallel, and a thermoelectric effect when a direct current flows. The temperature difference is generated on both sides of the module by means of cooling or heating refers to a solid state heat pump (solid state heat pump) using the cooling effect caused by the Peltier (Peltier) phenomenon.

The thermoelectric element is a next-generation environmentally friendly cooling method that breaks the existing cooling method of operating a compressor to circulate a refrigerant, and the current temperature control range is about -30 ° C to + 180 ° C.

In the present invention, the heating surface 28 and the cooling surface 26 of the thermoelectric element are exposed to the respective insulating spaces by using the insulating partition wall 10 as the boundary wall so that the refrigerator and the warming cabinet can be afforded at the same time.

That is, in general, the thermoelectric element 24 is concentrated and used in the cooling system, but in the present invention, the heat to be radiated is not discharged to the outside, but rather is exposed to the warming and storage side to simultaneously perform cooling and heating.

It is more preferable that the thermal element 24 also serves as the above-described thermal conductive panel 22, and the thermal conductive panel is in contact with the cooling surface 26 and the heating surface 28 of the thermal element 24 in each thermal insulation space. The heat conduction is performed to cool or heat the inside of the insulation space.

When such a thermoelectric element 24 is used, it is natural that a control unit (control unit) for controlling cooling and heat of the thermoelectric element is mounted, and the provision of the control unit using the thermoelectric element is general and detailed description thereof will be omitted.

In this case, however, since the heating of the thermoelectric element and the heating by the heat dissipation are operated in conjunction with each other, independent temperature control of the refrigerator and the refrigerator is difficult.

On the other hand, the power source is portable, the battery 34 may be used, in this case it is natural that a separate storage space is provided.

In addition, the power supply line can use the vehicle's cigar jack 34 for charging the battery 32 and for portable use.

As described above, according to the present invention, since the heat insulation space is divided into a heat insulation bulkhead of a portable insulation, there is an effect that the refrigeration and the warming are performed in a single case.

In addition, a seating groove in which a cooling pack or a hot pack is seated is formed in the heat insulating space, and a heat conducting panel which is in thermal contact therewith is disposed on the inner wall of the heat insulating space, thereby further increasing the cooling and heating functions.

In addition, when the thermoelectric element is mounted with the insulating partition wall as a boundary wall, the cooling through the cooling unit and the heating through the radiating unit are performed at the same time, so that all the use of the thermoelectric element cooling system is performed, and thus the portable cold / hot storage is operated.
