FIG. 1 is an exploded perspective view of a defroster according to the present invention, FIG. 2 is a partially broken cross-sectional view of the defroster shown in FIG. 1 in a used state, and FIG. 3 is shown in FIGS. It is a fragmentary sectional view showing the mode of use of the defroster. Referring to FIGS. 1 and 2, a defroster according to the present invention includes a first heat conductive plate 1,
And a second heat conductive plate 2. Thawed object 3 (see Fig. 3)
Is sandwiched between the first heat conductive plate 1 and the second heat conductive plate 2. The first heat conductive plate 1 and the second heat conductive plate 2 are made of a material having good heat conductivity. A typical example of such a material is a metal material.

At least one of the first heat conductive plate 1 and the second heat conductive plate 2 located on the lower side
Are provided with concave grooves 51 to 5 around the surface 201 in contact with the object to be thawed.
3 Although the concave grooves 51 to 53 are divided into three in the embodiment, they may be continuous as a whole. Groove 51
53 are arranged so as to surround the mounting area of the object 3 (see FIG. 3).

In using the defroster according to the present invention,
As shown in FIG. 3, an object to be thawed 3 such as frozen food is sandwiched between the first heat conductive plate 1 and the second heat conductive plate 2. When the thawing device is placed at room temperature, the temperature of the surface 101 of the first heat conductive plate 1 that is in contact with the air at room temperature is higher than the temperature of the back surface 102 that is in contact with the object 3 to be defrosted. Causes a temperature gradient in a direction of decreasing the temperature. Due to this temperature gradient, heat is conducted from the front surface 101 of the first heat conduction plate 1 to the back surface 102, and the object 3 to be defrosted in contact with the back surface 102 receives the conduction heat and is thawed. Second heat conductive plate 2
A similar heat conduction effect is also performed in.

As a result, the material to be thawed 3 is quickly defrosted without substantially impairing its quality and freshness. Further, care and cleaning are easy, and maintenance such as consumable repair is almost unnecessary and easy to handle. In addition, it is economical because it does not require electricity bills, and is excellent in portability and versatility.

The first heat conduction plate 1 has through holes 11 to 13 at three places, for example. Also, the second heat conductive plate 2
Has three guide rods 21 to 23 at positions corresponding to the through holes 11 to 13. When assembling the first heat conductive plate 1 and the second heat conductive plate 2, guide rods 21 to 23 are inserted into the through holes 11 to 13. Thereby, both 1-2
Are integrated, and mutual displacement in the front-back and left-right directions does not occur. The length of the guide rods 21 to 23 is determined in consideration of the size of the target object 3 to be thawed.

In the embodiment shown in FIGS. 1 and 2, the bases 210 to 230 of the guide rods 21 to 23 are provided with through holes 11 to 23.
13 has a larger diameter than the portions 211 to 231 to be inserted. Therefore, the guide rods 21 to 2 are inserted into the through holes 11 to 13 of the first heat conductive plate 1 in a state where the object 3 is not present.
3 is inserted and assembled (see FIG. 2), the first heat conductive plate 1 is received by the bases 210 to 230, and the lower surface of the first heat conductive plate 1 and the second heat conductive plate 2 A gap having a height h1 of the bases 210 to 230 is generated therebetween. For this reason, when the first heat conductive plate 1 is combined with the second heat conductive plate 2 in the non-use state, the first heat conductive plate 1 does not adhere to each other and the first heat conductive plate 1 is used in use. It can be easily removed from the second heat conduction plate 2. Providing the finger hooks 14 (see FIG. 1) around the back surface 102 of the first heat conductive plate 1 facilitates the work of removing the first heat conductive plate 1 from the second heat conductive plate 2.

The corners of the first heat conduction plate 1 and the second heat conduction plate 2 are formed in an arc shape, so that danger can be avoided.

It has concave grooves 51-53. According to this structure, the object to be thawed 3
With the thawing, the sap of water or biological components oozing out of the object 3 is received by the grooves 51 to 53. Therefore, it is possible to prevent the quality and freshness of the thawing object 3 from being impaired by the sap oozing from the thawing object 3 as the thawing object 3 is thawed.

8 to 11 show examples of the shapes of the concave grooves 51 to 53. FIG. In the example of FIG. 8, the concave grooves 51 to 53 have an arc on the bottom surface 410, and have a substantially vertical wall surface 4 thereon.
