A food storage system according to each embodiment of the present invention will be described below with reference to the drawings. The description will first describe the configuration of the embodiment, then the method of implementation, and finally other examples.
In addition, each embodiment shown below is an example of this invention, and does not limit this invention to each following embodiment.

<<First embodiment>>
Hereinafter, the invention according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. Symbol X in this embodiment represents a storage system. In addition, in FIG. 1, the thick line arrow represents the flow of air.

As shown in FIG. 1, the storage system X according to the present embodiment includes a storage unit 1 that stores bread, a control unit 2 that controls and adjusts the internal environment of the storage unit 1, the storage unit 1 and the control unit 2. and a connecting portion 3 for connecting the . Also, although not shown, the entire storage system X is covered with a heat-insulating cover.

As shown in FIG. 1 , the storage unit 1 has an air supply unit 11 to which air is supplied from the control unit 2 and an air discharge unit 12 for discharging the air inside the storage unit 1 .
The storage unit 1 is constructed by stacking stages of storage tanks 13 capable of storing a plurality of breads. It forms one storage unit 1. The buffer tank 14 provides temperature regulation and air filtration.

The air supply portion 11 is an insertion portion provided between the storage portion 1 and the control portion 2 through which air can flow in and out. In the present embodiment, the air supply part 11 is provided as a lattice-like gap part that is not shielded by the heat insulating material Q and the pan F in the bottom surface of the storage tank 13 .
A check valve may be provided in the air supply unit 11 so that air can flow in one direction from the control unit 2 to the storage unit 1 . Furthermore, the air supply section 11 may be configured to be covered with a rectifying plate so that the storage section 1 is uniformly supplied with air.

The air discharge portion 12 is an insertion portion provided between the storage portion 1 and the connection portion 3 through which air can flow in and out. In this embodiment, the portion connecting the buffer tank 14 and the connection portion 3 functions as the air discharge portion 12 .
A check valve may be provided in the air discharge section 12 so that the air can flow out in one direction from the storage section 1 to the connection section 3 .

The storage tank 13 is a substantially rectangular box-shaped member in a plan view having an open top surface and a grid-shaped bottom surface. As shown in FIG. 1, the upper surface and the bottom surface of the storage tank 13 are configured so that they can be fitted together while securing a space for storing bread therein.

As shown in FIG. 2, the bottom surface of the storage tank 13 has a lattice shape by arranging a plurality of void portions in a pattern. In addition, a plurality of pans F are placed on the bottom surface of the storage tank 13, so that gaps provided in a grid pattern are shielded. As a result, a blocking portion 131 that blocks the passage of air and an insertion portion 132 that allows the passage of air are formed on the bottom surface of the storage tank 13 . 2 and 3, the insertion portion 132 is represented by grid lines.

Preferably, the bottom area of the storage tank 13 is provided so as not to coincide with a constant multiple of the bottom area of the bread F to be stored. This prevents the pan F from being arranged without gaps, so that both the shielding portion 131 and the insertion portion 132 can be reliably formed.

More preferably, the pan F has a substantially rectangular parallelepiped shape, and the length of the plurality of pans F arranged in the width direction matches the length and/or width of the bottom surface of the storage tank 13 . As a result, when the bread F is properly placed in the storage tank 13, gaps other than the insertion portion 132 are less likely to be formed, and air control, which will be described later, can be easily performed.

The bread F in this embodiment is assumed to be a loaf of bread having a general size of about 25 cm in length, about 12.5 cm in width, and about 12.5 cm in height. That is, the length of the bread F is about twice the width of the bread F.
For example, in FIGS. 2 and 3, the length of the bottom surface of the storage tank 13 is five widths of the pan F, and the width thereof is three widths of the pan F. As shown in FIG. Accordingly, by arranging seven pans F as shown in FIGS. 2 and 3, the insertion portion 132 smaller than the bottom area of the pans F can be formed.

As shown in FIGS. 2 and 3 , the insertion portions 132 are provided close to corners of the bottom of the storage tank 13 . Here, in the two storage tanks 13 that are connected, the insertion portions 132 are provided at opposing positions in a plan view. As a result, the flow of air, which will be described later, spreads over the entire pan inside the storage tank 13 .

Further, a projecting guide or mark may be provided on the bottom surface of the storage tank 13 in order to assist in arranging the pan F at an appropriate position.

The buffer tank 14 is provided on the uppermost level of the storage unit 1 , has substantially the same outer shape as the storage tank 13 , and is connected to the storage tank 13 by the same mechanism as the storage tank 13 . The buffer tank 14 has a filter 141 that filters air and a lid portion 142 that covers the top.

The filter 141 is a fine planar member provided on the cross section of the buffer tank 14 in the width direction, and prevents impurities such as cross-sectional dust and dust of the buffer tank 14 from circulating in the storage unit 1, but it is not necessary. .

The heat insulating material Q is a plate-shaped or box-shaped heat insulating material such as polystyrene foam or polyurethane foam, and prevents heat radiation from the inside and the occurrence of dew condensation. It is preferable to attach the heat insulating material Q to each of the storage tanks 13, but it is particularly preferable to attach the heat insulating material Q to the uppermost stage of the storage unit 1 because heat tends to be trapped there.
Further, in the present embodiment, by cutting a part of the heat insulating material Q, the insertion portion 132 through which air is inserted between the storage tank 13 and the buffer tank 14 is formed.

The control unit 2 is a part having a function of adjusting air flow, temperature, and humidity inside the storage unit 1 and is provided to be connected to the storage unit 1 . In this embodiment, the control unit 2 has substantially the same outer shape as the storage tank 13 and is provided below the storage unit 1 .
The control unit 2 processes information from an air control unit 21 that controls the flow rate of air sent into the storage unit 1, a temperature control unit 22 that controls the temperature inside the storage unit 1, and a temperature sensor S to and a processing unit 23 for appropriately operating the control unit 21 and the temperature control unit 22, and information is transferred as shown in FIG. In addition, substantially the entire inner peripheral surface of the control unit 2 is covered with a heat insulating material Q, which prevents excessive heat supply to the adjacent container tank 13 and facilitates temperature control.

The air control unit 21 has the effect of agitating the air in the storage unit 1 by generating an air flow inside the storage system X. FIG.
In this embodiment, the air control unit 21 is provided as a circulator installed inside the control unit 2 toward the air supply unit 11 .

In the storage system X, the storage unit 1, the control unit 2, and the connection unit 3 integrally form a closed loop flow path. Pervasive throughout System X.
More specifically, as shown in FIG. 1, the air flow generated by the air control unit 21 flows through the air supply unit 11 into the storage tank 13, and passes through the insertion part 132 of the storage tank 13 one level above. It flows into the storage tank 13 one level higher, further flows into the buffer tank 14 one level higher through the insertion part 132 of the buffer tank 14 one level higher, and then passes through the air discharge part 12 to the connection part 3 . , and returns to the air supply section 11 .
As a result, an air flow path with a closed structure is formed, and a temperature-controlled air flow efficiently spreads to the storage system X.

The temperature control unit 22 adjusts the temperature inside the storage system X based on the temperature information obtained from the temperature sensor S, which will be described later, and adjusts the temperature inside the storage unit 1 so that the temperature in the storage unit 1 is optimal for the bread F. do.
In this embodiment, the temperature control unit 22 is provided as a heater installed behind the flow generated by the air control unit 21 inside the control unit 2, and is installed in the air from the front surface and the back surface. warm.

For example, if the bread F is a loaf of bread, the temperature in the storage unit 1 will be kept below 30°C by the temperature control unit 22, since E. coli, which causes food poisoning, tends to propagate when the ambient temperature rises above 30°C. Adjust so that
In this embodiment, the temperature inside the storage unit 1 is configured to be adjustable to 15 to 45.degree. C., preferably 25 to 36.degree.

The temperature sensors S include an outside temperature sensor S1 installed outside the storage system X to measure the outside air temperature, an intake temperature sensor S2 installed at the connection between the control unit 2 and the connection unit 3, and the control unit 2. By the supply temperature sensor S3 installed at the connection part with the storage unit 1, the storage tank temperature sensor S4 that measures the temperature of the bottom storage tank 13, and the buffer temperature sensor S5 that measures the temperature of the buffer tank 14 It is configured.
A temperature sensor S may be provided in each storage tank 13 .

By using the temperature sensor S, various information regarding the storage system X can be obtained.
For example, by comparing the temperature of the outside temperature sensor S1 and the temperature inside the storage system X, the amount of heat radiated from the bread storage system X can be estimated.
Also, by taking the difference between the temperature measured by the intake temperature sensor S2 and the temperature measured by the supply temperature sensor S3, the effect of heating by the air supply unit 11 and the temperature control unit 22 can be estimated.
Further, by comparing the storage tank temperature sensor S4 and the buffer temperature sensor S5, it can be estimated whether the hot air flow has reached the uppermost stage of the storage unit 1 or not.

Note that the temperature sensor S may have a function of measuring the dew point temperature and a function of measuring the wind speed separately, so that the humidity and the air flow rate can be measured and estimated.
Also, if the storage system X has high heat insulation, either one of the suction temperature sensor S2 and the buffer temperature sensor S5, which are located close to each other, may be provided. Either one of S4 may be provided.

Next, the user stacks the storage tank 13 and the buffer tank 14 on the control part 2 so that the positions of the insertion parts 132 are staggered to form the storage part 1 . After that, the connection part 3 that connects the uppermost part of the storage part 1 and the control part 2 is attached.

Finally, the user activates the control section 2 . The user sets the airflow and temperature of the storage section 1 so that the bread F is in an optimum state, and operates the control section 2 .
