2. Description of the Related Art Items such as bento that you do not want to cool
It must be transported while keeping it warm, but conventionally, it was packed in a heat-insulating container such as styrofoam at a bento manufacturing factory and delivered to a convenience store or the like by a carrier. In such a method, since the heat source is only the lunch itself, no matter how excellent the heat insulation performance of the heat insulation container is, there is a limit to the heat retention performance.

On the other hand, in recent years, as in Japanese Patent Application No. 2-307925 filed by the applicant earlier, wheels are attached to the bottom of the heat insulation box to make it movable, and a cold storage agent is arranged in the heat insulation box. It is also considered to construct a refrigerator in which cold air cooled by a cold storage agent is circulated by a blowing means driven by a storage battery to cool articles inside, and the refrigerator itself is transported by a transport vehicle.

Therefore, when transporting the bento etc., it is conceivable that a heat storage box is constructed in which the inside of the heat insulation box is heated by a heater fed from a storage battery, and the heat storage box itself is transported.

[0005]

The storage battery, which is the power source for such a refrigerator or refrigerator, is heavy in itself and has harmful substances such as electrolyte solution inside. It is impossible because of the need to prevent damage.
On the other hand, if it is simply attached to the outer surface of the heat-insulating box, there are problems that it may become an obstacle during transportation and the center of gravity of a storage such as a refrigerator or a refrigerator may become unstable.

[0006] The present invention has been made to solve the above problems, by providing a storage battery in which the storage battery has a low center of gravity by arranging the storage battery at an appropriate position, and which does not hinder mobile transportation. The purpose is to

[0007]

According to the present invention, a heat insulating box 5 having a storage chamber 7 for storing articles therein, wheels 4 and 4 for movement attached to a bottom surface 5A of the heat insulating box 5, and storage are provided. Room 7
In a storage (heat storage 1) equipped with temperature control means (electric heater 8) for adjusting the internal temperature and a storage battery 11 for supplying electric power to the electric heater 8, wheels 4 and 4 facing the storage battery 11 face each other. It is attached to the bottom surface 5A of the heat insulating box 5 between the two.

[0008]

According to the storage (heat storage 1) of the present invention, the storage battery 11 is arranged in the dead space between the wheels 4, 4 on the bottom surface 5A of the heat insulating box 5. In addition, since the heavy storage battery 11 is arranged below the refrigerator 1, the refrigerator 1 itself has a low center of gravity. Furthermore,
Since the storage battery 11 exists outside, maintenance is easy, and even if the internal liquid leaks, it does not affect the articles in the storage chamber 7. Furthermore, since the storage battery 11 exists between the wheels 4 and 4, it does not interfere with the claws F of a forklift or the like when the storage box 1 is transported.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a perspective view of a refrigerator 1 as an embodiment to which the present invention is applied, FIG. 2 is a longitudinal sectional view thereof, FIG. 3 is an electric circuit diagram, and FIG. 4 is a bottom view. Further, FIG. 5 is a schematic block diagram showing a distribution flow of transporting the goods from the client to the recipient while keeping the goods in a warm state.

First, the distribution flow in which the warm storage 1 as the storage of the present invention is used will be described with reference to FIG. That is,
In the delivery base SK where the carrier Y described later stands by,
The heating cabinet 1 is connected to a power supply device 2 described below, and a storage battery 11 described below is charged. After that, the warm storage 1 is loaded on the carrier Y and heads to the client T of the bento manufacturing factory or the like, where the food to be stored such as bento is stored in the warm storage 1. This storing operation is performed while the warm storage 1 is loaded on the transport vehicle Y, or once the warm storage 1 is unloaded from the transport vehicle Y.

The warm storage 1 containing the bento etc. is transported and delivered to the receiver U such as a convenience store while being loaded on the carrier Y (in this case, the carrier Y also serves as a delivery vehicle). In some cases, the delivery vehicle SH once delivers the delivery vehicle to another delivery base SH near the destination, and then the delivery base SH transfers the delivery vehicle to the delivery vehicle SH for delivery to the recipient U.

In the warm storage 1, the electric heater 8 heats the storage chamber during this process to keep food such as bento box stored at + 15 ° C., for example. Of course, it is conceivable to use the above-mentioned refrigerator for storing refrigerated food or frozen food instead of the warm storage 1 or to mix the warm storage 1 and the refrigerator in the carriage Y. This is shown in the broken line of the carrier Y of FIG. After this transportation and delivery is completed, the transport vehicle Y returns to the delivery base SK with the storage cabinet 1 being loaded.

Next, in the refrigerator 1, the vertical heat insulating box 5 having an opening formed on one side surface, the movable wheels 4 attached to the four corners of the bottom surface 5A, and the opening are closed so as to be openable and closable. And a heat-insulating door 6, which has a storage chamber 7 formed therein,
A heating plate 9 having an electric heater 8 which constitutes a temperature adjusting means is attached to both back sides of the lower part of the storage chamber 7.

Wheels 4 facing each other on both front sides of the heat insulating box 5,
As shown in FIG. 4, a heat insulating cover 10 is attached to the bottom surface 5 </ b> A between the storage battery 4 and a storage battery 11 and a low-capacity heater 12 for keeping the storage battery 11 warm. At this time, the heat-insulating cover 10 is substantially wheel 4,
It is preferable to arrange them so as to be within the left and right projection area of No. 4. Since the storage battery 11 is arranged between the wheels 4 and 4 in this manner, even if the claw F of the forklift truck is inserted below the bottom surface 5A in order to load and store the storage box 1 in the delivery base SK as shown in FIG. It does not get in the way.

A socket portion 13 for supplying power to the storage battery 11 is formed on the upper front portion of the heating cabinet 1. Further, the power supply device 2 includes a plug 14 for connecting to a commercial AC 100V power supply AC, a power supply unit 15 for generating a low voltage of DC 12V from the AC power supply 100V supplied from the plug 14, and a power supply unit 15. It is composed of a connector 16 which is detachably connectable to the socket portion 13 of the refrigerator 1 in order to output the produced direct current 12V. Since the direct current voltage generated by the power supply unit 15 is as low as 12V, the refrigerator 1 is loaded on a refrigerating vehicle or the like to cause dew condensation on the outer surface thereof, resulting in high safety for the user even if electric leakage occurs.
In addition, since the power supply device 2 is configured separately from the heat storage cabinet 1, the structure of the heat storage cabinet 1 itself is simplified and durability against impacts is increased, and the wiring of the heat storage cabinet 1 itself is minimized. Therefore, the countermeasure against dew condensation becomes easy, and the damage of the equipment by the electric leakage is suppressed.

The electrical connection of these is shown in FIG. That is, the changeover switch 17 and the thermostat 18, which constitutes a temperature adjusting means for detecting the temperature of the storage chamber 7 and opening and closing the contact at a set temperature, for example, + 15 ° C., are connected to the storage battery 11 in series with the electric heater 8. Further, the electric heater 12 is connected between the storage battery 11 and the connection point of the changeover switch 17 and the thermostat 18. Storage battery 1
1 is a power supply device 2 via a socket portion 13 and a connector 16
It is connected to the.

The operation will be described. In the delivery base SK, the changeover switch 17 is initially opened, and the storage battery 11 is charged with the connector 16 connected to the socket portion 13 in this state. When this charging is completed, the connector 16 is removed and the refrigerator 1 is loaded on the transport vehicle Y. Changeover switch 17 after loading or before loading
Is closed and kept in a warm state. In the warming state, the discharge current of the storage battery 11 is supplied to the electric heater 8 by the control of the thermostat 18, and the electric heater 8 intermittently generates heat to keep the temperature inside the storage chamber 7 at + 15 ° C. which is the set temperature.

In this way, the electric heater 8 can keep the inside of the storage chamber 7 warm for a relatively long time by supplying power from the storage battery 11. Further, the wheels 4 in which the storage battery 11 becomes a dead space,
Since it is arranged between the four, the loading efficiency on the transport vehicle Y is improved. In particular, since it is between the wheels 4 and 4 on the bottom surface 5A, it does not interfere with the claw F of the forklift and does not hinder the cargo handling work. Further, the relatively heavy storage battery 11 is used as the warm storage 1.
Since it is located at the bottom of the refrigerator 1, the center of gravity of the refrigerator 1 can be lowered, and it is difficult for the refrigerator 1 to fall over when the wheels 4 are used for movement. Furthermore,
Since the storage battery 11 is outside the storage chamber 7, even if the internal solution leaks, the food in the storage chamber 7 will not be damaged, and maintenance such as replacement in this case can be easily performed.

When a refrigerating vehicle is used as the transportation vehicle Y, the temperature around the cover 10 for accommodating the storage battery 11 is low, such as + 7 ° C., but the inside of the cover 10 is insulated and the heater 12 is used.
As it is also kept warm, it is possible to secure electric power.

Further, in the embodiment, the warm storage 1 is taken as an example of the storage, but the storage is not limited thereto, and as described above, the cool storage is provided and the cold air cooled by the latent heat of the storage is driven by the storage battery. The present invention is also effective in a refrigerator in which a DC fan motor is used to circulate in a storage room. In this case, the regenerator and the DC fan motor constitute the temperature adjusting means.

[0021]

As described above, according to the present invention, since the storage battery is arranged between the wheels which are dead spaces, the loading efficiency on the transport vehicle is improved. Especially, because it is between the wheels on the bottom, it does not interfere with the nails of the forklift,
It does not interfere with cargo handling work. Further, since the relatively heavy storage battery is located at the bottom of the storage, the center of gravity of the storage can be lowered, and the storage battery is less likely to fall when moving.
Further, since the storage battery is located outside the storage room, even if the internal solution leaks, it does not damage the food in the storage room, and in this case, there is an excellent effect that maintenance such as replacement can be easily performed.
