[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cooling device for cooling, freezing, dehumidifying, drying and thawing fresh food such as marine products, agricultural products and livestock products and processed products thereof by an air blast method.

[0002]

[Prior art]

 The cooling device of this type is as shown in FIG. 5, in which a cooling chamber 25 is formed by a horizontal partition plate 22 in the center of a refrigerator 21 made of a heat insulating material, and a cooler chamber 24 is provided above the cooling chamber 25. The fan 28 is installed above the cooler chamber 24, and the cool air cooled by the cooler 29 and discharged from the cooler chamber 24 by the fan 28 passes through the duct 23, the suction chamber 26, and the flow rectifying plate 27, and is then covered. Cool air is blown onto the cooling object 10 to remove heat, moisture, etc., and then is sucked into the cooler chamber 24 through the straightening vane 31 and the blowing chamber 32. In this way, the cool air is blown as shown by the solid arrow. It will circulate in the direction. In such a cooling device, since the cool air circulates in one direction and flows as described above, the object to be cooled 10 on the side hit by the cool air is in sufficient contact with the cool air, so that the heat transfer efficiency is high and the heat, Moisture is removed to a satisfactory degree, but the object to be cooled 10 on the opposite side does not come into sufficient contact with cold air, so heat transfer efficiency is poor and heat and moisture are not removed to a satisfactory degree. Therefore, there is a problem that unevenness in temperature and unevenness in drying occur in the object to be cooled 10 and the quality is deteriorated.

[0003]

[Problems to be solved by the device]

 Therefore, as a solution to such a problem, a duct that allows cold air to flow in one direction is provided on one side of the cooling chamber, and a duct that flows in the opposite direction is provided on the other side, and a damper that alternately opens and closes both ducts. It has been proposed that the cooling air is alternately introduced into the cooling chamber from the duct by switching the damper (Japanese Patent Publication No. 1-60757). However, such a device has a large number of constituent parts, has a complicated structure, is expensive, and has a problem that the operation is complicated.

Therefore, an object of the present invention is to solve the problems of the conventional cooling device as described above, to prevent uneven quality of the object to be cooled and uneven drying, and to reduce the quality, and to reduce the number of constituent parts. The purpose is to provide a cooling device that has a simple structure, is inexpensive, and is easy to operate.

 In order to achieve the above-mentioned object, the invention according to claim 1 is such that a horizontal partition plate is attached above a storage compartment made of a heat insulating material, and a duct is formed on the upper part of the compartment and a duct is formed on the lower part. A cooling chamber is formed, ventilation chambers are formed on both sides of the cooling chamber, and a cooler is installed on one side, and the duct, the cooling chamber, the cooler, and the ventilation chamber form a cold air passage, and an upper passage of this cold air passage. It is characterized by being equipped with a fan that can switch the air flow direction in both forward and reverse directions. According to the invention of claim 2, a horizontal partition plate is attached to the upper part of the chamber made of a heat insulating material, a duct is formed in the upper part thereof, and a cooling chamber is formed in the lower part thereof, and the ventilation chambers are provided on both sides of the cooling chamber.

It is characterized by.

[0006]

[Action]

 In the device of claims 1 and 2 as described above, the object to be cooled is stored in the cooling chamber, the cooler is operated to rotate the fan in one direction, and the cool air cooled by the cooler is passed through the cool air passage. The object to be cooled in the cooling chamber is cooled from one side by circulating it in one direction, and then the fan is rotated in the other direction to allow cold air to flow in the other direction in the cold air passage to cool the object to be cooled in the cooling chamber to the other side. By simply cooling the fan from one direction to another, by simply switching the rotation direction of the fan, the cool air flows not only in one direction but also alternately in the other direction, and alternately contacts both sides of the object to be cooled to make sufficient contact. Therefore, the heat transfer efficiency is high as a whole and heat and moisture are removed to a satisfactory degree, and it is possible to prevent deterioration of quality due to uneven temperature and uneven drying of the object to be cooled.

【Example】

 In the first embodiment of the present invention shown in FIGS. 1 and 2, reference numeral 1 denotes a box made of a heat insulating material, a horizontal partition plate 2 is attached to the upper part of the box 1, and a duct 3 is formed on the upper part thereof. A cooling chamber 4 is formed in the lower part of the cooling chamber 4, ventilation chambers 8 and 9 are formed on both sides of the cooling chamber 4, a cooler 6 is installed on one side of the cooling chamber 4, and the duct 3, the cooling chamber 4, the cooler 6 and the ventilation are provided. A cold air passage is formed by the chambers 8 and 9, and a fan 7 that can switch the air blowing direction between the forward and reverse directions is installed in the cold air passage. In such a cooling device, when the object to be cooled 10 is placed in the cooling chamber 4 and the cooler 6 is operated to rotate the fan 7 in one direction, the cool air cooled by the cooler 6 is shown by a solid line in FIG. As shown by the arrow, the object 10 to be cooled in the cooling chamber 4 is cooled from the left by circulating in the cool air passage in the counterclockwise direction. When such cooling work continues for a predetermined time, the fan 7 is rotated in the other direction by a timer (not shown) to rotate in the other direction, and the cool air flows in the cool air passage in the clockwise direction as indicated by the dotted arrow, and the cooling air in the cooling chamber 4 is cooled. Cooled product 10 is cooled from the right side. In this cooling device, as described above, only by changing the rotating direction of the fan 7, the cool air flows not only in one direction but also in the other direction and alternately circulates, and hits both sides of the object to be cooled 10 alternately. Since they are in sufficient contact with each other, the heat transfer efficiency is high as a whole, and heat, moisture, etc. are removed to a satisfactory degree, and it is possible to prevent the temperature of the object to be cooled 10 from becoming uneven and the drying to be uneven, thereby preventing the quality from deteriorating. It is preferable that the fan 7 is designed so that the blades have a warp angle in both forward and reverse directions so that the same air flow rate and the same static pressure can be secured during both forward and reverse rotations.

In the second embodiment of the present invention shown in FIGS. 3 and 4, the same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted, and different parts will be mainly described. The difference between this embodiment and the first embodiment is that the cooler 6 is installed on the upper part of the partition plate 2 and the cooler 6 is equipped with a fan 7 that can be switched in both forward and reverse directions. Since it is the same as that of the first embodiment, its explanation is omitted.
