DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quick freezer for freezing and storing fresh foods and processed foods such as meat and fish.

[0002]

2. Description of the Related Art FIG. 2 is a sectional view of a conventional example, and FIG.
2 shows a flow diagram of the wind in the refrigerator of FIG. 2 and 3, reference numeral 1 denotes a main body case having a storage box 2 formed by filling a heat insulating material between an inner box and an outer box, and having an opening on the front surface and a door 3 for closing the opening. Reference numeral 4 denotes a tray which is stored vertically in the storage 2 and on which the food 5 is placed, 6 is an evaporator through which a refrigerant is circulated from a cooling unit 7, and 8 is cold air cooled by the evaporator 6 to the food 5. The internal fan 9 is a partition for preventing the fan 8 from being re-aired by the internal fan 8 before being cooled by the evaporator 6 when the air from the internal fan 8 is blown to the food 5 and returned to the evaporator 6. A plate 10 is a core temperature sensor for detecting a central temperature by being inserted into the representative food 5 in the food placed on the tray-4, 11 is an internal temperature sensor for detecting the internal temperature, 1
Reference numeral 2 denotes a control device that controls the operation of the cooling unit 7 and the internal fan 8 based on the detection values of the core temperature sensor 10 and the internal temperature sensor 11. 2 and 3, a refrigerant from a cooling unit 7 is circulated in an evaporator 6 arranged along one side wall of a storage 2 formed in the main body case 1 to cool air in the storage. To generate cool air around. The cold air is blown by the fan 8 in the refrigerator to the food 5 placed on the tray 4 like the flow of wind shown by the arrow in FIG. 2 to freeze the food 5 and hit the door 3 on the side where there is no fan in the refrigerator. It is bent and blocked by the partition plate 9, returns to the front of the evaporator 6 at a location different from the inside fan 8, is cooled through the inside of the evaporator 6, and is circulated to the suction side of the inside fan 8. In this freezing operation, in order to maintain the quality of the food 5, in order to maintain the quality of the food 5, the detection value of the core temperature sensor 9 inserted in the representative food 5 or the detection value of the in-chamber temperature sensor 10 is taken into the control device 11, and the food 5 is completely frozen. The internal fan 8 is continuously operated until it passes through the maximum ice crystal formation zone and reaches the freezing temperature zone.

After all the foods are frozen, the core temperature sensor 9 or the internal temperature sensor 10 controls the operation of the internal fan and the cooling unit, and performs the cooling control for maintaining the temperature at a predetermined temperature.

[0004]

However, the conventional configuration has the following problems when the food is frozen. The flow of the cooling air from the gap between the trays causes the cooling time to be delayed or the smell to be transferred to another food, thereby deteriorating the quality of the food. Since there is a gap in front of the tray, when the door is opened, the cool air inside the refrigerator leaks and the temperature inside the refrigerator rises, and the operating rate of the refrigerator increases due to the deterioration of food quality and the rise in temperature inside the refrigerator, resulting in lower power consumption. To rise.

[0005] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to prevent cooling air from flowing out of a gap between trays so that an odor does not transfer to other foods. Another object of the present invention is to provide a quick freezer with less leakage of cold air when a door is opened.

[0006]

According to a first aspect of the present invention, there is provided a method of forming a storage space by filling a heat insulating material between an inner box and an outer box to form a storage box therein. Main body case having a part and a door for closing the opening, a plurality of trays arranged vertically in the storage, an evaporator arranged along one side wall of the storage, and cold air around the evaporator. In the quick freezer for freezing the food placed on the trays, a partition is provided for partitioning the trays vertically arranged in the storage, and the trays are arranged one by one. It is characterized in that a private room in which the front and rear surfaces for storing are opened is formed.

According to a second aspect of the present invention, in the quick freezer according to the first aspect, a partition is provided on a front surface of the tray to close a front opening of a private room in which the tray is stored.

According to the first and second aspects of the present invention, even when different foods are placed on each tray, cold air blown on the foods on the tray leaks to the tray on which other foods are placed. And the smell is less likely to be transferred to other foods. In addition, when the door is opened, the leakage of cool air is reduced, and it is possible to prevent the operating rate of the refrigerator from increasing.

[0009]

1 shows the structure of a main part of an embodiment of the present invention. FIG. 1A is a front view when a door is opened.
(B) shows a side sectional view of (a). In this FIG.
Reference numeral 1 denotes a partition formed by filling a heat insulating material between an inner box and an outer box, and in which a tray 4 of a storage 2 having an opening on the front side is vertically arranged and stored, and a partition 2a separates each tray 4. Doors 3 for storing trays 4 one by one, forming a private room with front and rear surfaces opened, and closing an opening at the front of the storage 2.
The main body case 4a is connected to the front of the tray 4,
A partition for closing the front opening of the private room, 5 is a food placed on the upper part of the tray 4, 6 is an evaporator for circulating a refrigerant from a cooling unit 7, 8 is cold food cooled by the evaporator 6 to the food 5. An internal fan to be blown, 10 is a core temperature sensor which is inserted into the representative food 5 in the food placed on the tray-4 and detects a central temperature, 11 is an internal temperature sensor which detects the internal temperature, 12 Is the cooling unit 7 based on the values detected by the core temperature sensor 10 and the internal temperature sensor 11.
And a control device for controlling the operation of the internal fan 8.

The embodiment shown in FIG. 1 is different from the conventional example shown in FIGS. 2 and 3 in that the trays 4 are simply arranged vertically and stored in the storage 2 in the conventional example. The partition 4a is vertically divided by a partition wall 2a to form and store a private room for each tray, and a partition 4a is provided continuously to the front surface of the tray to close the front opening of the private room.

Here, a plurality of partition walls 2a are provided up and down from the front of the internal fan 8 to the opening end of the storage box 2, and the partition walls 2a divide the storage box 2 in the vertical direction so that each tray is divided. Each room has a private room. Then, the cooling air from the inside fan 8 flows forward from the front through each of the compartments partitioned by the partition walls 2a, hits the partitions 4b, is bent, and returns to the front of the evaporator 6 where the inside fan 8 is not installed. After passing through the evaporator 6, it flows again forward by the in-compartment fan 8, and cool air circulates in each private room.

The partition 4a has a forward bent portion serving as a handle when pulling out the tray 4.
The tray 4 is configured to be able to be taken in and out of the private room.

[0013]

According to the present invention, since the food is placed on the tray stored in the private room, the cool air blown to the food is returned to the evaporator without being leaked toward another tray and cooled. Therefore, the circulation of cold air is effectively performed, and the freezing time is shortened compared to the conventional freezer,
This has the effect of preventing the smell from being transferred to other foods. In addition, since a screen is provided on the front of the tray, when the door is opened, cold air does not leak out of the refrigerator, and the temperature change inside the refrigerator is reduced, so that deterioration of food quality can be prevented and the operating rate of the refrigerator decreases. This has the effect of reducing power consumption.
