It should be interpreted as a meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, so at the time of the present application, they can be replaced. It should be understood that there may be many equivalents and variations.

1 is a perspective view showing a refrigerator dedicated to cooking and storage containers according to a preferred embodiment of the present invention, and FIG. 2 is a longitudinal sectional view showing the inside of a refrigerator dedicated to cooking and storage containers according to a preferred embodiment of the present invention. "A" in 3 is an enlarged view of part A according to a preferred embodiment of the present invention, "B" is an enlarged view showing another embodiment of the main body, and "C" is an enlarged view showing another embodiment of the sealing member. It is an enlarged view, and FIG. 4 is a longitudinal cross-sectional view showing a heat conduction plate according to a preferred embodiment of the present invention.

1 to 3, the refrigerator 100 for exclusive use of cooking and storage containers of the present invention includes a main body 110, a heat conduction plate 120, a thermoelectric element 130, a heat dissipation member 140, and a discharge fan ( 150), and further includes a sealing member 160.

First, the main body 110 may be formed of a metal material, but is preferably formed of a synthetic resin material that is advantageous in terms of weight and manufacturing. It is natural that the inside of the main body 110 is provided with a space for mounting each of the above components, and a through hole 112 communicating with the inside is formed on the upper surface, and a discharge hole for discharging internal heat to the outside on one side. (114) is formed. The discharge hole 114 is preferably formed on the bottom surface, but may be formed on the side surface according to circumstances. It is more preferable to configure such a body as a type that is separated up and down for convenience of assembly.

In addition, it is preferable that the upper surface of the main body 110 has a slope that gradually decreases toward the outside so that water droplets due to dew condensation can be transported to the outside when they fall on the upper surface of the main body 110, and more preferably the main body An upwardly protruding edge 116 is formed on the upper edge of the 110 so that even if water droplets fall to the upper surface of the main body 110 due to condensation, they are not leaked to the outside.

Next, the heat conduction plate 120 is inserted into the through hole 112 of the main body 110, preferably inserted into the through hole 112 inside the main body 110, and the cooking container and storage container to be seated It is for delivering cool air by directly contacting or close to the bottom surface of the heat conduction plate 120 by looking at the height W of the heat conduction plate 120 and the main body 110 as shown in "A" of FIG. It can be seen that the upper side protrudes higher than the upper surface of the main body 110 . This is because when the heated cooking vessel is placed on the top of the main body 110, the heat conduction plate 120 touches and the upper surface of the main body 110 is spaced apart from the bottom surface of the cooking vessel, so that the main body 110 is deformed or damaged due to high heat. to prevent damage. At this time, as shown in “b” of FIG. 3, a heat-resistant silicon pad 118 is provided on the upper surface of the main body 110 to cover the separation space generated on the upper surface of the heat conduction plate 120 and the main body 110. can do. Even in this case, this is to prevent the main body 110 from directly touching the bottom surface of the cooking vessel, and removing the heat-resistant silicon pad 118 is the same result in that the heat conduction plate 120 protrudes higher than the upper surface of the main body 110. , It should be recognized that there is another example modified in this way.

On the other hand, as shown in FIG. 4, a concave mounting groove 122 is formed on the bottom surface of the heat conduction plate 120 to mount a thermoelectric element 130 to be described below. If it is formed concavely and the thermoelectric element 130 is mounted therein, it is advantageous to reduce heat loss. In addition, a groove 124 is formed along the shape on the edge of the upper surface, and a packing 126 is inserted therein, which is It is provided to prevent slippage and reduce heat loss at the same time by ensuring that the container is in close contact with the bottom surface when seated.

Next, the thermoelectric element 130 is referred to as a Peltier element using heat absorption and heat generation by the Peltier effect, and is installed close to the lower side of the heat conduction plate 120 to control the temperature. This Peltier effect is a phenomenon in which when two types of metal ends are connected and a current flows through them, one terminal absorbs heat and the other terminal generates heat, depending on the direction of the current. The cooking container placed on the heat conduction plate 120 can be stored in a cool manner. Furthermore, since heating operation is also possible according to the direction of the current, a heating function may be further included, and storage at room temperature as well as cold storage is possible. Furthermore, the cooking vessel may be directly heated. Since the heat transfer element 130 adjusts the amount of heat absorption and heat generation according to the amount of current, it is possible to precisely control the temperature even though the capacity is small. It is natural that the present invention also configures the temperature control stepwise.

Next, the heat dissipation member 140 is provided to be installed close to the lower side of the thermoelectric element 130 to expand the heat dissipation area so that heat can be quickly dissipated, and is also referred to as a heat dissipation fin.

Next, the discharge fan 150 is disposed close to the heat radiating member 140 to quickly discharge the heat emitted from the heat radiating member 140 to the outside through the discharge hole 114 of the main body 110. .

Finally, the sealing member 160 is provided to block foreign matter or water from entering the main body 110 in the gap generated by fitting the heat conduction plate 120 into the through hole 112, This is possible by being positioned between the outer surface of the heat conduction plate 120 and the inner wall of the through hole 112, the sealing member 160 is configured to cover the entire outer surface of the heat conduction plate 120 as shown in FIG. It is preferable to be configured to have a heat insulating function as well as blocking the inflow of foreign substances.

On the other hand, as shown in "c" of FIG. 3, a seating portion 162 protruding higher than the height of the heat conduction plate 120 may be integrally formed on the top of the sealing member 160, and the seating portion (162)), it is advantageous to empty the inside in the form of an empty space so that the contraction action can easily occur. This is because when the cooking vessel is placed, the seating part 162 touches the bottom surface of the cooking vessel first before other surfaces, mitigates the impact, and then contracts to guide the bottom surface of the cooking vessel to contact the heat conduction plate 120. . When the seating portion 162 is formed in this way, shock is mitigated and the bottom surface of the cooking vessel and the top surface of the main body 110 are sealed, thereby blocking cold air from leaking out.

Now, in the following, the state of use of the refrigerator dedicated to cooking and storage containers according to the present invention constructed as described above will be described.

5 "A" is a longitudinal cross-sectional view showing a state of use of the refrigerator exclusively for cooking and storage containers according to a preferred embodiment of the present invention, "B" is an enlarged view of part B, and FIG. 6 is a preferred embodiment of the present invention. It is a partially enlarged cross-sectional view showing a state of use of a refrigerator dedicated to cooking and storage containers to which another sealing member according to the example is applied.

Referring to "A" of FIG. 5, a cooking container 180 after cooking or a storage container storing food is placed on top of the main body 110 of the refrigerator 100 for cooking and storage containers according to the present invention and operated. It can be stored at a low temperature to prevent food from spoiling or deteriorating. That is, when the user sets the storage temperature to a low temperature, for example, 4 degrees, through a control unit (not shown), cold air is generated due to the operation of the thermoelectric element 130, and the cold air cools the heat conduction plate 120. In other words, since the cooking vessel 180 seated on the heat conduction plate 120 can be stored at a low temperature, it is possible to prevent food from spoiling or changing. The above temperature setting is presented as an example, and it is possible to set the temperature down to below zero. Conversely, it is also obvious that the cooking container 180 can be stored at room temperature by heating it according to the direction of the current.

At this time, as shown in "B", the sealing member 160 is installed in the gap generated between the heat conduction plate 120 and the main body 110 to prevent foreign substances or moisture from entering the inside, which is safe and convenient. will be able to use In addition, since the heat conduction plate 120 protrudes higher than the upper surface of the main body 110, even if the heated cooking vessel 180 is placed, it will not come into direct contact with the upper surface of the main body 110, so it can be used safely, As a result, condensation occurs on the surface of the cooking container 180 and water droplets may fall. The dropped water drops move outward along the inclined surface of the upper surface of the main body 110 and flow into the main body 110. It is not possible to significantly reduce the occurrence rate of minor failures, and in particular, when the edge 116 is formed on the edge, the water droplets are not discharged to the outside and stored on the upper edge of the main body 110, so that the surroundings will not become messy.

On the other hand, as shown in FIG. 6, when the seating portion 162 is formed above the sealing member 160, the shock is absorbed when the cooking vessel 180 is seated, and the weight of the cooking vessel 180 is immediately absorbed. While being contracted by the heat conduction plate 120, the bottom surface of the cooking vessel 180 is brought into contact with or placed close to the heat conduction plate 120. Here, an effect of being sealed along the edge of the bottom surface of the cooking vessel 180 can be created due to the seating portion 162, so that generated cold air can be prevented from leaking to the outside, and improved functions can be expected.

"A" and "B" of FIG. 7 are partial enlarged cross-sectional views showing another form of the sealing member according to a preferred embodiment of the present invention.

First, referring to "A", the sealing member 160 is inserted into the gap between the main body 110 and the heat conduction plate 120, but shows a case where only the upper part is fitted, and "B" is the sealing member 160 ) shows a case where each can be provided on the lower side or upper side of the gap. In this way, no matter what form the sealing member 160 has, it will be recognized that it is the same as the present application for the purpose of eventually blocking the gap.

8 is a perspective view showing a refrigerator dedicated to cooking and storing containers according to another embodiment of the present invention, and FIG. 9 is a longitudinal sectional view showing a refrigerator dedicated to cooking and storing containers according to another embodiment of the present invention. "A" and "B" are longitudinal cross-sectional views showing different shapes of the cover according to another embodiment of the present invention.

Referring to FIGS. 8 and 9 , the refrigerator 100' for exclusive use of cooking and storage containers according to another embodiment of the present invention also has a body 110 like the refrigerator 100 for exclusive use of cooking and storage containers according to a preferred embodiment of the present invention. ), a heat conduction plate 120, a thermoelectric element 130, a heat dissipation member 140, and a discharge fan 150, but is characterized in that it further includes a cover 170.

Since the main body 110, the heat conduction plate 120, the thermoelectric element 130, the heat dissipation member 140, and the discharge fan 150 are the same as the above-mentioned configurations, a separate description thereof will be omitted and the same reference numerals are used. And here, we will take a look at the cover, which is an additional component.

The cover 170 is coupled to the upper part of the main body 110 to provide a refrigerating chamber isolated from the outside, and can actively block the outflow of cold air, so that more improved performance can be expected. In addition, if the cover 170 is covered when storing the cooking container 180 or storage container without a lid, it will be possible to block the inflow of pests. Above all, it is characterized in that the refrigerating function can be further improved because it is possible to form a refrigerating chamber that is blocked from the outside due to the cover.

At this time, as shown in "A" of FIG. 10, the cover 170 is preferably configured in a corrugated tube form or in a multi-stage form as shown in "B" so that its height can be adjusted. This makes it possible to adjust the height according to the height of the cooking container 180 or the storage container, reducing unnecessary space, thereby improving performance and convenient storage and portability. Furthermore, it is preferable that the cover 170 is formed of a transparent material so as to be able to see through the inside.
