In this case, there is a problem in that the manufacturing process of the cold storage device is complicated. Since the heat conductive block 25 is welded and bonded to the lower surface of the storage container 21, it is difficult to bring the storage container 21 and the heat conductive block 25 into close contact with each other, and heat generated from the thermoelectric element 27 is stored in the storage container. When delivered to (21), there is a problem that heat loss occurs in the seam of the storage container 21 and the heat conduction block 25.

An embodiment of the present invention is intended to provide a cold / warm storage apparatus having improved heat efficiency delivered to an article in a storage container.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for efficiently describing the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

2 is a perspective view illustrating a cold / warm storage apparatus according to an embodiment of the present invention. In FIG. 2, the cover of the storage container is omitted for convenience of explanation. Here, not only the refrigerator and the warmer are used but also the case where they are used only as a refrigerator or a warmer.

2, the cold storage apparatus 100 includes a storage container 102, a heat conduction block 104, a thermoelectric element 106, a heat dissipating unit 108, and a circulating fan 110.

The storage container 102 has a storage space of a predetermined shape therein. In the storage container 102, for example, an article such as a drink can and a water bottle can be accommodated. The storage container 102 is made of a material having excellent thermal conductivity, such as aluminum, copper, magnesium, tungsten, stainless steel, or the like.

A plurality of seating grooves 121 may be formed on the bottom surface of the storage container 102. Here, the seating groove 121 may include at least one first seating groove 121-1 and at least one second seating groove 121-2. The first seating groove 121-1 may be formed on the bottom surface of the storage container 102 along the longitudinal direction of the storage container 102. [ The second seating groove 121-2 may be formed on the bottom surface of the storage container 102 along the width direction of the storage container 102. [

In the first seating groove 121-1 and the second seating groove 121-2, an article such as a beverage can or a water bottle is seated. At this time, a beverage can or a water bottle with a long length can be seated in the first seating groove 121-1, and a beverage can or a water bottle with a short length can be seated in the second seating groove 121-2.

The first seating groove 121-1 and the second seating groove 121-2 may be formed in a shape corresponding to the shape of the portion where the article is seated. For example, when the beverage can having a columnar shape is seated in the first seating groove 121-1 and the second seating groove 121-2, the first seating groove 121-1 and the second seating groove 121-2 121-2 may be formed in an arc shape. In this case, the entire one side of the beverage can can stably be seated in the first seating groove 121-1 and the second seating groove 121-2, whereby the area of the beverage can contacting the storage vessel 102 So that heat generated in the thermoelectric element 106 can be efficiently transferred to the beverage can.

The first seating groove 121-1 and the second seating groove 121-2 are formed on the bottom surface of the storage container 102. However, the present invention is not limited to this, And the second seating groove 121-2 may be formed. Although the seating groove 121 is illustrated as being formed on the bottom surface of the storage container 102, the seating groove is not limited thereto, and the seating groove may be formed on the inner surface of the storage container 102. In this case, when the article is stored upright in the storage container 102, the side surface of the article can be seated in the mounting groove. As such, the seating groove can be formed in at least one of the bottom surface and the inner surface of the storage container 102.

In addition, the inner surface of the storage container 102 may be surface treated with a material comprising at least one of alumina, magnesium oxide, sodium oxide, zirconium oxide, potassium oxide, graphene, and Carbon Nano Tube (CNT). In this case, when the heat generated in the thermoelectric element 106 is transferred to the article stored in the storage container 102 via the storage container 102, the wavelength of the far-infrared ray changes in the surface-treated surface inside the storage container 102 So that the heat can be transferred deep into the inside of the article, thereby allowing the article stored inside the storage container 102 to be cooled or heated more quickly.

At least one heat conducting pin 124 may be formed on the inner surface of the storage container 102. For example, the heat conductive fins 124 may be formed in a portion of the inner surface of the storage container 102 where the heat conductive block 104 is formed. In this case, the heat transfer area through the heat conduction block 104 at the inner surface of the storage container 102 can be widened, thereby improving the heat conduction efficiency. Here, the heat conductive fin 124 may be integrally formed with the storage container 102, or may be separately manufactured and then coupled to the inner surface of the storage container 102.

The heat conduction block 104 is formed on one side of the storage container 102. The heat conduction block 104 is formed to have a thickness enough to secure a required heat insulation distance between the heat dissipating portion 108 and the storage container 102. At this time, the heat conduction block 104 is formed integrally with the storage container 102.

For example, when the die casting method is used, the heat conductive block 104 can be formed integrally with the storage container 102 when the storage container 102 is manufactured. At this time, the thermally conductive pins 124 may also be formed integrally with the storage container 102. As such, by forming the heat conductive block 104 integrally with the storage container 102, the manufacturing process of the storage container 102 can be simplified, and the storage container (through the heat conductive block 104 in the thermoelectric element 106) can be simplified. 102, it is possible to minimize the heat loss that occurs when the heat is transferred to.

The thermoelectric element 106 is formed on one side of the heat conduction block 104. The thermoelectric element 106 refers to a device capable of converting electrical energy into thermal energy or heat energy into electrical energy. Here, the electric energy is converted into thermal energy through the thermoelectric element 106. At this time, the storage container 102 can be cooled or heated according to the polarity of the power applied to the thermoelectric element 106. [

For example, in hot weather such as summer, heat is absorbed on one surface of the thermoelectric element 106 (that is, the surface in contact with the heat conduction block 104), and the other surface of the thermoelectric element 106 In this case, the storage container 102 is cooled through the thermoelectric element 106 to cool the hot / cold storage device 100 to the refrigerator (not shown) .

In cold weather such as winter, heat is emitted from one surface of the thermoelectric element 106 (that is, the surface in contact with the thermoelectric block 104) by reversing the polarity of the power source applied to the thermoelectric element 106, (That is, the surface in contact with the heat radiating portion 108) of the heat sink 106. In this case, the storage container 102 can be heated through the thermoelectric element 106, so that the cold / warm storage apparatus 100 can be used as a warming-up apparatus.

The heat dissipating unit 108 is installed on one side of the thermoelectric element 106 to emit heat generated from the thermoelectric element 106.

The circulating fan 110 is installed on one side of the thermally conductive pin 124 in the storage container 102. At this time, the circulating fan 110 may be installed on the front surface of the heat conducting pin 124. The circulation fan 110 allows the heat transferred through the heat conduction block 104 to circulate in the inner space of the storage container 102. In this case, heat transfer efficiency to the article housed in the storage container 102 can be improved. That is, the article stored in the storage container 102 is not only directly subjected to heat transfer through the portion in contact with the storage container 102, but also indirectly through heat circulated internally by the circulation fan 110 The heat transfer efficiency to the article stored in the storage container 102 can be improved. A detailed description thereof will be described later with reference to FIG. 3 and FIG.

3 is a cross-sectional view of a cold / warm storage apparatus according to an embodiment of the present invention.

Referring to FIG. 3, articles 150 such as drink cans or water bottles are seated in the seating grooves 121 in the storage container 102. In this case, since the entire one side of the article 150 is in contact with the storage container 102, the area of contact with the storage container 102 can be widened and the heat transfer efficiency can be increased.

The thickness of the portion where the first seating groove 121-1 and the second seating groove 121-2 are formed in the storage container 102 can be made thicker than the thickness of the other portion. The first seating groove 121-1 and the second seating groove 121-2 are portions where the beverage can is seated and contact with the storage container 102. The first seating groove 121-1 and the second seating groove 121-2, The heat efficiency to be transmitted to the beverage can in the storage container 102 can be further improved.

For example, if the thickness of the other part of the storage container 102 is 1 to 2 mm, the first seating groove 121-1 and the second seating groove 121-2 are formed to have a thickness of 3 to 10 mm can do. When the storage container 102 is manufactured by, for example, a die casting method, the thickness of the portion where the first and second seating grooves 121-1 and 121-2 are formed through a simple process is greater than the thickness of the other portions So that it can be formed thick.

When the thickness of the other portion of the storage container 102 is 2 mm and the portion where the first and second seating grooves 121-1 and 121-2 are formed is 5 mm, 106) was applied for 30 minutes. The temperature difference between the portion where the thermoelectric element 106 is formed and the portion farthest from the thermoelectric element 106 is different from the temperature difference of 4.5 ° C. in the other portion of the storage container 102, 121 - 1 and the second seating groove 121 - 2 have a temperature difference of 7 ° C. By forming the portions where the first seating grooves 121-1 and the second seating grooves 121-2 are formed to be thicker than other portions as described above, the heat efficiency transmitted to the beverage can in the storage container 102 can be further improved .

At this time, when the first seating groove 121-1 formed in the longitudinal direction of the storage container 102 is formed from the thermoelectric element 106 provided on one side of the storage container 102 to the other side of the storage container 102 , A heat pass line is formed from the thermoelectric element 106 to the first seating groove 121-1, thereby enhancing heat transfer efficiency.

In the embodiment of the present invention, the heat conductive pin 124 is formed on the inner surface of the storage container 102 and the circulating fan 110 is provided on the front surface of the heat conductive pin 124, So that heat can be circulated through the inner space of the storage container 102. In this case, since the article 150 stored in the storage container 102 receives heat also by the air (cold or warm) circulated by the circulation fan 110, the efficiency of heat conduction can be further improved.

That is, the article 150 housed in the storage container 102 receives heat generated from the thermoelectric element 106 through the portion contacting the storage container 102 primarily. At this time, since the article 150 is seated in the seating groove 121 in the storage container 102, the area in contact with the storage container 102 can be widened. Further, since the thickness of the portion where the seating groove 121 is formed is thicker than the other portion, the heat efficiency transmitted to the article 150 seated in the seating groove 121 can be improved.

The article 150 stored in the storage container 102 receives heat generated from the thermoelectric element 106 through the air (cold or warm) circulated by the circulating fan 110 in a secondary order. In this case, since the air circulating inside the storage container 102 transfers heat to the portion of the article 150 that is not in contact with the storage container 102, heat efficiency to be transferred to the article 150 can be increased . In this case, the temperature of the article 150 stored in the storage container 102 can be quickly reached to the target temperature. The heat generated in the thermoelectric element 106 is circulated through the heat conduction block 104 and the heat conduction pin 124 and the circulation fan 110 is circulated through the heat conduction block 104 and the heat conduction pin 124. [ When circulated by the fan 110, the heat conduction efficiency can be increased while minimizing heat loss.

In the embodiment of the present invention, the heat conduction block 104 and the heat conduction pin 124 are integrally formed with the storage container 102, so that the manufacturing process of the cold / warm elongated device 100 can be simplified, It is possible to minimize the heat loss generated in the process of transferring the heat generated in the storage container 102 to the storage container 102, thereby maximizing the heat efficiency delivered to the product 150.

4 is a cross-sectional view illustrating a cold / warm storage apparatus according to another embodiment of the present invention.

Referring to FIG. 4, the cold / warm storage apparatus 100 may further include an ultraviolet illumination unit 130. The ultraviolet illumination unit 130 may be installed on the upper side of the inner surface of the storage container 102. However, the present invention is not limited thereto, and the ultraviolet illumination unit 130 may be installed at a position other than the above (for example, a cover of a storage container).

The ultraviolet illumination unit 130 serves not only as a light illuminating the inside of the storage container 102 but also as a sterilizing function for sterilizing the inside of the storage container 102. In this case, the inside of the storage container 102 can be sanitarily managed by ultraviolet rays generated from the ultraviolet light illuminator 130 by sterilizing the inside of the storage container 102.

Here, at least one of the inner surface of the storage container 102 and the bottom surface of the storage container cover may be surface treated with an ultraviolet barrier coating agent. In this case, it becomes possible to prevent the storage container 102 and the storage container cover from being discolored or discolored by ultraviolet rays.
