DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components, and the same reference numerals will be used to designate the same or similar components. Detailed descriptions of known functions and configurations are omitted.

1 and 2, reference numeral 100 designates a cold storage refrigerator for distribution according to the embodiment of the present invention. The refrigerator compartment 100 basically includes a housing 104 having a space capable of storing foods and the like and a heat exchanger 102 installed on the upper side of the housing 104 and performing heat exchange with the outside air.

A door 106 is installed on the front surface of the housing 104 to open and close the inner space of the housing 104. The door 106 may be provided with a door handle 108.

A thermoelectric element for generating cold heat is installed inside the housing 104. Since the thermoelectric element is installed on the upper portion of the housing 104, it is possible to supply cold air having a relatively high density downward, which is advantageous for convection.

The thermoelectric element has a cold portion 116 for discharging cold heat and a heating portion (not shown) spaced apart from the cold portion and buried in the heat transfer block 118 side. The heat unit (not shown) transfers heat through the heat-transfer block 118 and releases heat to the atmosphere by a cooling fan (not shown) formed inside the heat exchanger 102.

The cooling and heating unit 116 includes a pair of cooling and heating plates 130 and 132 spaced from each other and a cooling frame 134 connecting the cooling and heating plates 130 and 132 to each other. The latent heat material 126 is charged in the latent heat accumulation holes 128, which are spaces formed between the pair of the cooling / heating plates 130 and 132.

The latent heat material 128 is made of two or more kinds of mixed materials or compounds and has a concentration of a eutectic point. As the latent heat material 128, a known technique can be used, and a mixture of water and urea can be used.

Due to the above-mentioned latent heat material 128, it is possible to store the remaining cold heat when using the cold storage compartment 100. Particularly, if the cold storage is operated by operating the cold storage refrigerator 100 intensively during a time when the electricity rate is low, it is possible to save a considerable part of the electric bill, which is economical. In addition, when a power failure occurs due to an accident or the like, it is possible to maintain the lead of the fresh product stored for a predetermined time by using the heat that has been stored.

A convection chamber 120 is formed in the cooling and heating unit 116 to transfer cold heat generated from the cooling and heating unit 116 to the inside of the housing 104 by convection.

The convection chamber 120 has a space therein, and at least one intake fan 122 is installed at a lower portion of the convection chamber 120. At least one air supply mechanism 124 is disposed in the lower portion of the convection chamber 120 around the intake fan 122. In the embodiment of the present invention, the suction fans 122 are arranged in a line in the center in the width direction of the cooling / heating plate 132, and the air supply devices 124 are arranged in a row on both sides of the suction fan 122.

The air inside the housing 104 is forced to be sucked into the convection chamber 120 by the suction fan 122 and cooled by the cold heat transmitted from the cooling plate 132 inside the convection chamber 120 The air is discharged again through the air supply mechanism 124 and is lowered. Since the cooled air is relatively more dense than the surrounding air, convection occurs in the direction of the arrow shown in Fig.

The heat exchanger 102 is provided with a control panel 110 and the control panel 102 may be installed outside or inside the housing 104 or outside the door 106.

A thermometer is installed inside the housing 104 to measure the temperature inside the housing 104. The control panel 110 compares the measured temperature with the set temperature to supply electricity to the thermoelectric element do.

In particular, thawing can be accomplished by cutting off electricity supplied to the thermoelectric element, or by changing the pole of the current applied to the thermoelectric element, so that the cooling part located inside the housing 104 emits heat. In addition, it is possible to control the time taken from the freezing to the defrosting by the control panel 110 at the time of defrosting, and in particular, it is possible to control the temperature inside the housing to rise linearly as shown in FIG.

In addition, a rechargeable battery may be installed on one side of the housing 104. In other words, it is possible not only to store electricity by the latent heat material 126 but also to save the distribution cost required for refrigeration by storing electricity in advance at a time when the electric charge is relatively inexpensive. In addition, The quality of the fresh product stored together with the food product 126 can be maintained longer.

The cold storage refrigerator 100 according to the embodiment of the present invention is basically configured as described above. Hereinafter, with reference to FIG. 4, the circulation process by the cold storage refrigerator 100 will be described as an example of semi-refrigeration.

In order to manufacture the semi-finished product, first, the senses are harvested (S10) and stored temporarily in a warehouse (S20). After storage, if the sensation is full, it is peeled (S30) and dried in a well-ventilated area (S40). When the semi-finished work is completed in this way, individual or plural pieces are wrapped (S50).

Then, the packaged half-carpentry is loaded into the cold storage refrigerator 100 to start refrigeration. Therefore, the half-life can be stored in the frozen state (S60). The temperature inside the housing 104 can be kept constant at a predetermined temperature by the control panel 110. Further, it is possible to preliminarily store surplus cold heat in the latent heat material 126 or to charge the rechargeable battery when the semi-transparent case is stored.

Thereafter, when the semi-transparent circulation is started, the refrigerator compartment 100 itself is transported to a container or the like. The electricity required for the operation of the cold storage refrigerator (100) can be carried without special electricity supply if the battery can be fully operated only by considering the circulation time. In addition, if the transportation time is long as in the case of exporting, it is possible to freeze and circulate without supplying a special facility such as a refrigeration container by simply supplying electricity to the refrigeration compartment 100.

Then, the defrosting is started in consideration of the defrosting time from the time when the display is started. At this time, the thawing does not instantaneously raise the temperature of the frozen frozen food 100, but gradually increases the temperature with time as shown in Fig. 5, so that the flavor of the half- It is desirable to keep the value of the product so that it does not float.

Also, it is possible to use the above-mentioned cold storage refrigerator 100 itself as a commodity shelf. In this case, the door 104 or the housing 104 may be made of a transparent material so that the consumer can visually confirm the half-finished product stored therein.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that
