DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for freezing various foods such as cooked rice, vegetables and seafood.

[0002]

2. Description of the Related Art As a conventional freezing apparatus of this type, a cooling air suction fan for cooling air discharged from the cooling device and a cooling air induction duct connected to a discharge side of the fan are provided in a refrigerator provided with a cooling device. And a storage portion for the frozen food connected to the guide end of the duct.

[0003]

The food freezing apparatus described in the above-mentioned prior art has the following problems in the freezing operation because the storage section of the food to be frozen and the duct are integrally connected.

[0004] In other words, in a specific example, if the color or flavor of cooked rice, such as pilaf, is now switched to a different type of frozen rice, such as white rice, the color and taste of the pilaf are already stored in the storage unit. Since the white rice is frozen as it is on the inner surface, the white rice naturally undergoes a color or taste shift when it is frozen. We perform cleaning work of inner wall, but this cleaning work is effective if we use water,
Since the duct is connected to the housing part, there is a concern that water may enter the duct, so it is not possible to do so. Therefore, it is not preferable, but at present, it is performed only by wiping with a cloth or the like. In addition, since the cleaning operation is performed by inserting a hand into the storage unit in a small storage, there are some extremely complicated operations.

Accordingly, the present invention provides a structure in which a tray can be attached to and detached from a duct in a refrigerator, so that freezing can be performed without causing color or taste transfer when switching and freezing foods as in the prior art. It is an object of the present invention to eliminate the necessity of cleaning the tray in the inside.

[0006]

SUMMARY OF THE INVENTION In order to solve the problems of the prior art, the present invention provides a fan provided with a cooler, a fan for sucking cool air discharged from the cooler, and a discharge side of the fan. A food freezing apparatus having a duct connected to the duct and a storage section for the frozen food to be connected to the duct and through which the cold air is sucked, wherein the storage section is detachably attached to the duct, and a large number of The invention is characterized in that it is formed by a portable tray integrally provided with the vent hole of (1).

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a storage body constituted by a heat insulating panel. The storage body 1 has an entrance 3 provided with an opening / closing door 2. A cooler 5 having a cooler fan 4, a high static pressure fan 6 having a cool air outlet facing the suction side, and a discharge port of the fan 6 are provided in the storage body 1. And a storage section A for the frozen food to which cold air is blown through the duct 7.

Accordingly, the gist of the present invention is to
Is constituted by a portable tray 9 which is detachable from the duct 7 and has a plurality of vent holes integrally provided on the bottom surface 8.

The height of the tray 9 is about 30 in this embodiment.
It has a small cylindrical shape of about 60 centimeters in diameter and about 60 centimeters in diameter, and has a flange-like mounting portion 9a for the duct formed at the lower peripheral edge.

The duct portion to which the tray 9 is attached and detached is
In this example, a flange 10 is formed by a chamber 10 having an outlet formed on the entire upper end, and a flange-shaped mounting portion 10 on which the mounting portion 9a of the tray 9 is placed.
a is formed so as to protrude, and the two mounting portions 9a and 10a are detachably connected to each other by a fastener (not shown).

The ventilation holes provided on the bottom surface 8 of the tray 9 are formed by providing a metal plate constituting the bottom surface with a large number of horizontal tunnel-like holes parallel to this surface, not shown. ing.

Directly above the chamber 10, a stirring blade 11 intervening at a depth of the tray 9 on the chamber is exposed, and the stirring blade 11 is connected to a motor 12 that rotates forward and backward. 1 and is supported so as to be detachable or vertically movable.

[0013]

The cold air discharged from the chamber 10 is supplied to the tray 9
Are blown into the tray through the bottom surface 8 of the tray, and the food to be frozen in the tray is floated and frozen sequentially while being stirred by the stirring blades 11. In addition, in this example, the frozen food is taken out of the refrigerator through a not-shown outlet provided on the lower side surface of the tray 9.

When the frozen food is, for example, a pilaf or the like, and after the pilaf is frozen, the next step is to switch to, for example, freezing of rice, the tray used for freezing the pilaf is removed from the chamber 10 and another tray is removed. The chamber 1
Change to 0, put white rice in this tray and freeze as before.

The tray 9 removed from the chamber 10 may be taken out of the refrigerator through the entrance 3 and washed with water so that the tray 9 can be used as a tray for storing the next different food to be frozen.

The food to be frozen is put into the tray while the tray is mounted in the chamber 10, or
Although not particularly shown, the food may be put in from the outside of the container through a supply means such as a conveyor penetrating the inside and outside of the container, and the frozen food may also be put in the container from the tray outlet described above. In the case where secondary freezing is required in addition to the above, the above-mentioned outlet is connected to a tray of a secondary freezing device (not shown) by a conveying means such as a conveyor, and
Next, it may be taken out on the side of the freezing apparatus.

[0017]

According to the present invention as described above, the following effects are obtained. (A) A container for storing frozen food, which is connected to a duct and into which cool air is blown through the duct, is formed by a portable tray, and the tray is detachably mounted on the duct. Therefore, when various frozen foods such as colors and flavors are to be switched and frozen, each frozen food can be stored individually in each tray and frozen for each tray. The conventional problem of taste transfer can be completely eliminated. (B) After the food to be frozen is completely frozen, the tray can be removed from the duct and taken out of the refrigerator for cleaning, so that complicated cleaning in a narrow refrigerator as in the related art is unnecessary, and the water is washed outside the refrigerator. And complete and sanitary cleaning can be performed. (C) Since individual trays can be used, it is possible to effectively contribute to freezing of a small amount of various kinds of foods. (D) At the same time, since the tray can be taken out from the inside or outside of the refrigerator, for example, the frozen food at normal temperature is stored outside the refrigerator in a tray at normal temperature and brought into the refrigerator without any temperature difference between them. Therefore, it is possible to eliminate the problems of the tray, the frozen food, and the icing caused by the temperature difference at the beginning of freezing.
