Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frozen storage having a tray in a storage chamber and freezing food placed on the tray by cold air circulating in the storage chamber.

[0002]

2. Description of the Related Art When handling a large amount of food for business purposes and freezing these foods, a freezer as disclosed in Japanese Patent Publication No. 58-48825 is used.

As shown in the front view of FIG. 6 (the front door is removed for convenience of explanation) and the sectional view of FIG. 7, the freezer has a storage chamber inside a heat-insulating box 1 having an open front. 2 and the cooling chamber 3 are vertically partitioned from each other, and a cooler 4 and fans 5a and 5b above and below the cooler 4 are arranged in the cooling chamber 3, while the storage chamber 2 has an L-shaped cross section. The tray supporters 6 and 6 are arranged so as to extend in the depth direction and face each other, and a front pull-out tray 7 that slides in and out on a plurality of tray supports 6 and 6 arranged above and below is provided. ing. In addition, 17 and 17 are tray columns to which the tray supports 6 and 6 are attached. A machine room 8 is provided at the top of the heat insulation box 1.
A compressor 9, a condenser 11, and a condenser fan 12 that form a refrigeration cycle with the cooler 4 are installed therein. Although not shown, the cooling chamber 3 and the storage chamber 2
In the partition wall 3a of the
Cold air outlets are formed corresponding to the fans 5a and 5b. Therefore, when the refrigeration cycle is operated, cold air is blown into the storage chamber 2 and circulated, and the food on the tray 7 is frozen. Although the food may be placed directly on the tray 7, it is better for individual hygiene and placing the food on the tray 7 to store the food in a container for storing the food as described later. It is convenient and preferable.

The front opening of the heat insulating box 1 is divided into upper and lower openings 14a and 14b by the partition 13, and the upper and lower openings are formed by filling the openings 14a and 14b with hard polyurethane having a high heat insulating property. Two front doors 15a, 15b
Is attached to the right or left by a hinge or the like so as to be openable and closable, so as to close and open the storage chamber 2.

[0005] Then, various foods are stored in the freezer thus constructed and frozen. In that case, when the food to be stored is ready or when the food is manufactured, the food is lined up on the tray 7 and when the food is almost full, the front door 15
Open a and 15b and slide the tray 7 on the tray supports 6 and 6 to store it. Depending on the food, for example, in the case of boiled noodles produced by a continuous type boiled noodle manufacturing device, the boiled noodles may be placed side by side in a tray, but if that is the case, the noodles placed on the tray first will be the last one. The noodles will grow before they are placed on the tray 7, and if frozen in this situation, the texture of the boiled noodles will be lost when thawed. Therefore, the tray 7 is installed in advance in the freezer and the continuous type boiled noodles manufacturing device is used. Each time the noodles are cooked, the front door 15a of the freezer,
It is preferable to open the tray 15b, pull out the tray 7 from the inside of the storage chamber 2, put the boiled noodles one by one into the pulled-out tray 7, and then return them to the storage chamber 2 again.

In any case, various foods stored by a method suitable for foods are rapidly frozen by the cold air circulating in the storage chamber 2 in a turbulent state.

[0007]

By the way, in the case of freezing food, the freezer is pre-cooled and the doors are not opened and closed until the food is put in and all the food is frozen. Although it leads to quality improvement, in reality, when the food to be stored is prepared as described above, and when the food is manufactured, it is stored in small amounts and frozen.

However, in the case of the above-mentioned conventional freezer, when the door is opened for storage, the storage chamber is completely opened. Therefore, when a tray containing frozen food is stored, When the frozen food is additionally stored, cold air flows out from the gap 30 (see FIG. 7) between the trays and outside air flows in. As a result, there has been a problem that the temperature of frozen food already stored and the ability to freeze the stored food due to new freezing are lowered. Also,
When food is put in one by one like the above-mentioned boiled noodles, the door is frequently opened and closed, the number of cold air outflow between the trays is increased, the cooling power is reduced, frost is accelerated on the cooler, and the defrosting time is extended. There is a drawback in that the interval is shortened and the cooling power is eventually lowered.

The present invention has been made in view of the above-mentioned points, and a damper for preventing the outflow of cold air is provided at the tray outlet provided corresponding to each tray, so that the trays other than the trays in which food is put in and taken out are provided. It is an object of the present invention to provide a frozen storage which can prevent cold air from flowing out from a place, maintain a high cooling capacity, and can be stably frozen and stored without deteriorating the quality of stored food.

[0010]

A cooling chamber in which a cooler and a fan are arranged inside a heat insulating box, and the inside is cooled by the cold air generated in the cooling chamber, and a plurality of stages are provided vertically. A storage chamber having a front drawer type tray, a front door that opens and closes a front opening formed in the front of the storage chamber, and a tray outlet formed at a position of the front opening facing the tray, A damper for preventing cold air outflow, which is axially supported by the upper end of the tray outlet and abuts on the front wall of the tray to close the tray outlet.

A cooling chamber in which a cooler and a fan are arranged inside the heat insulating box, a storage chamber for cooling the inside by the cool air generated in the cooling chamber, and a plurality of upper and lower chambers provided in the storage chamber A front drawer type tray that is provided stepwise and has a notch formed in a part of the front side of the side wall, a front door that opens and closes a front opening formed in the front surface of the storage chamber, and the front opening A tray outlet formed at a position facing the tray,
A damper for axially supporting the outlet of the tray and for preventing the outflow of cold air that slides along the cutout portion of the tray side wall when the tray is pulled out is provided.

[0012]

The tray outlet is provided corresponding to each of the front drawer type trays which are installed vertically in the storage chamber, and the tray outlet is provided with the openable and closable damper whose upper end is pivotally supported.
For this reason, only the damper that tries to store food is opened and closed, and the other tray outlets do not open.If you open the front door as in the past, all the front of the storage room will be opened and cool air will be released. It is possible to prevent as much as possible that air leaks and outside air enters. As a result, stable freezing of the stored items is maintained, and cooling power reduction is avoided.

When the damper is closed, the lower end of the damper hits the front wall of the tray to hold the damper in a stable closed state, so that the seal for preventing the outflow of cold air is sure.

Further, when the damper is rotated by providing cutouts on both side walls of the tray, the cutouts serve as relief portions for smooth opening and closing of the damper. Further, when the tray is pulled out to take out the frozen food, the damper is gently turned outward to open along the notch, and the tray can be pulled out smoothly.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. It should be noted that components that are the same as or correspond to those of the conventional device shown in FIGS.

Each front opening 14a, 1 of the upper and lower storage chambers 2
4b, as shown in FIG. 1, the vertical plates 40, 40 and the vertical plates 4
The partition plates 40A and 40A in which a plurality of support plates 16 are laterally provided to the 0 and 40 to form a plurality of openings are arranged.
The spacing between the support plates 16 arranged vertically is set to a height width width that is sufficient for loading and unloading the tray 7.
Therefore, by arranging the partition plates 40A and 40A,
The divided openings serve as tray outlets 18 corresponding to the respective trays 7.

The partition plates 40A and 40A can be fixed to the front openings 14a and 14b by screwing the vertical plates 40 and 40 to the front ends of the tray columns 17 and 17, respectively.

Further, without using the partition plates 40A and 40A, both ends of each support plate 16 are directly fixed to the front ends of the tray columns 17 and 17 at predetermined intervals in the vertical direction by a simple method so that the tray outlet 18 can be fixed. , 18 can also be configured.

Reference numeral 19 is a damper for preventing the outflow of cold air which is attached to each tray outlet 18, and is pivotally fixed to the support plate 16 by means of hinges 21 and 21 at the upper ends as shown in FIGS. , Can be rotated back and forth
It is designed to open and close 8.

Here, the damper 19 is rotated and opened inward when the food is stored or the tray 7 is inserted, but it is normally in a vertical posture due to its own weight. At this time, the lower end of the damper 19 is the front wall 7 of the tray 7 stored in the storage chamber 2.
The front wall 7a restricts the movement of the damper 19 in the outward direction. As described above, the tray outlet 18 is kept closed to prevent cold air from flowing out. That is, the length of the damper 19 is formed to be in contact with the front wall 7a of the tray 7, and as shown in FIG.
9. The double bent portion 19a formed at the lower end of the tray 9 overlaps the double bent portion 7b at the upper end of the tray front wall 7a from the inside to ensure a seal for preventing the outflow of cold air, and to secure each tray outlet 18 to the individual damper 19. Is blocked. As a result, when the front doors 15a and 15b are opened, cold air can be prevented from flowing out between the trays 7 other than when the damper 19 is opened and food is taken in and out. Since the lower end of the damper 19 and the upper end of the tray front wall 7a, which are frequently opened and closed, are the double-folded portions 19a and 7b as described above, the mechanical strength is sufficient.

FIG. 4 shows the movement of the damper 19 when the container 22 containing food is stored in the already stored tray 7. At the tip of the container 22 to be placed, the damper 19 is pushed inward with the hinges 21 and 21 as a fulcrum, and is completely stored in the tray 7. At this time, notches 23, 23 are formed at the tip portions of the left and right side walls 7c, 7c of the tray 7 so that the damper 19 can be opened and closed without any hindrance. Also, 2
Reference numeral 4 denotes a guide plate which is also provided as a partition in the center of the tray 7 when the containers 22 are accommodated in the tray 7 in two rows, and when the container 22 is put into the tray 7, the guide plate It can be inserted smoothly by 24. Then, when the last container 22 enters along the guide plate 24, the container 22 is stored at a position before the cutout 23 as shown in FIG. 3 so as not to hit the damper 19 that opens and closes.

In this way, a large number of containers 22 each containing food are stored in the tray 7, and these foods are frozen in the storage 2.

FIG. 5 shows the movement of the damper 19 when taking out the frozen food together with the tray 7. When the tray 7 is pulled out to a certain extent, the lower end of the damper 19 slides along the R-shaped notches 23 and 23 formed on the side walls 7c and 7c, and the damper 19 rotates outward. Start opening. If the tray 7 is further pulled out as it is, the tray 7 is pulled out by further opening the damper 19.

Here, by making the height H ₂ of the container 22 lower than the height H ₁ of the side walls 7c and 7c of the tray 7, the damper 19 first pulls out the side wall 7c of the tray 7 when the tray 7 is pulled out. , 7c to open, and the containers 22 pushed in several rows in the depth direction are inserted into the damper 19
The tray 7 can be pulled out smoothly without touching.

With the above construction, therefore, when food is stored in the tray 7 which is supported by the tray supports 6 and 6 and is installed in the storage chamber 2, either of the front doors 15a and 15b is opened. open. Even if the front doors 15a and 15b are opened, the tray outlets 18 corresponding to the respective trays 7 are closed by the dampers 19, so that the cold air outflow from the storage chamber 2 is very small.

Then, when the container 22 containing the food is pushed in from the damper 19 of the tray 7 to be stored, the damper 19 is rotated inward to open and can be stored in the tray 7. When the container 22 is stored,
The damper 19 returns to its original vertical posture by its own weight and rotates, and its lower end 19a is kept in contact with the front wall 7a of the tray 7 from the inside to block the tray outlet 18, and cold air outflow is prevented.

As described above, the damper 19 is opened each time the container 22 is inserted, and the containers 22 can be easily packed in several rows in each tray 7 and placed and stored. Since only the dampers 19 to be stored are opened and the other dampers 19 are closed, cold air can be prevented from flowing out between the tray 7 and the tray 7 which are not in the storage operation, and the outside air can be prevented from entering. The quality of food frozen in the tray 7 is not significantly affected.

The food stored in each tray 7 in this way is driven by the compressor 9 to operate the refrigeration cycle and the fan 5
When a and 5b rotate, the cold air circulated and supplied into the storage chamber 2 is frozen.

Also, when the tray 7 is put in the tray 7 outside the storage chamber 2 and the tray 7 is put in the tray 7, the damper 19 can be easily opened because the tip of the tray 7 is opened inside. Of course, also in this case, since the presence of the damper 19 prevents the cold air from flowing out from the other tray take-out port 18 that has not been put in or taken out, it is possible to prevent the cooling power from decreasing and the food freezing ability from decreasing.

When taking out frozen food, either of the front doors 15a and 15b is opened, the damper 19 corresponding to the food to be taken out is slightly opened, and the tray 7 is opened.
The front wall 7a is pulled out to the front with the tray 7 or the like. As the tray 7 is pulled out, the lower end of the damper 19 slides along the notch 23 on the side wall of the tray 7 as shown in FIG. , 6 can be slid on and pulled out easily.

Then, the tray 7 in which the food is taken out and emptied
Is put in the storage chamber 2 again, the damper 19 is opened inward at the tip of the tray 7 and stored at a predetermined position, and the front wall 7a of the stored tray 7 and the lower end of the damper 19 overlap and hit. Ensures a seal to prevent cold air outflow.

[0032]

As described above, according to the present invention, a tray outlet is provided corresponding to each tray at the front opening of the product storage chamber in which slide type trays are arranged vertically, and each tray outlet is also provided. A damper for preventing outflow of cold air that is pivotally supported on the upper end of the tray and opens and closes forward and backward is provided, and this damper is normally in contact with the front wall of the tray to close the tray outlet. For this reason, when storing products or when loading and unloading trays, only the dampers at the storage and loading / unloading points are opened and closed, and other tray outlets are closed. Absent.

As a result, the temperature rise of the already stored products is prevented, and the quality of the stored products is not deteriorated.

Further, since the damper is surely closed and held, invasion of outside air is prevented as much as possible, and a constant freezing temperature can be maintained in the storage chamber.

According to the second aspect of the present invention, when the tray is pulled out, it slides in the notch formed in the side wall of the tray and the damper is opened easily to the outside. Since it does not hit, the tray can be pulled out easily, and frozen food can be taken out easily.
