Description

[Detailed explanation of the invention] This invention is designed to keep daily items belonging to a distribution system, such as milk and eggs, at an appropriate temperature for 2 to 3 hours before they are processed by a refrigerated truck, when they are jointly delivered using a refrigerated truck. This relates to a cold storage box for receiving daily deliveries.

Refrigeration devices such as freezer cases and refrigerated cases with cold storage functions have been available at retail stores for a long time, but these are for consumers and are not used in large quantities shipped jointly by wholesalers or manufacturers. Daily delivery items are usually left at stores or on the street early in the morning, unless the store receives them and disposes of them immediately.
It takes two to three hours for the store to process the items, so they are left exposed to sunlight or damaged by wind and rain, especially in the summer. Therefore, the quality of the products could not be guaranteed, resulting in increased storage and transportation costs for retailers. There has not yet been a cooling device for simple storage and cold storage of daily items that can solve the above problems and be compatible with future organization of distribution systems.

As a means to solve the above problems, we created a vertically long box in which the front door, left and right side panels, back panel, top panel, and bottom panel are assembled airtight using colored steel panels sandwiched and filled with a lightweight insulating material such as polyurethane foam. , except for the door, the opposing parts of each plate are fastened with removable fittings,
The joint joints are appropriately sealed, a pallet shelf is removably installed inside, a cooling device unit case compatible with the bottom plate and housing cooling equipment is removably installed, and the lid of the case is removably installed. A cold air outlet with a cold air duct erected on a part of the door and a cold air suction port on the other side, and packing containing magnetic rubber that sticks to the box is provided on the back of the door for receiving daily items. This is an attempt to obtain a cold storage box.

This invention relates to an improvement of the ``cold box for receiving daily deliveries'' of Utility Model Publication No. 4-15110 filed by the applicant of this invention. The invention of the earlier application was to install a cold storage board under the top plate of the cold storage box, that is, on the top shelf.
Cold storage was achieved by natural convection of cold air due to the latent heat of dissolution of the cold storage agent. Therefore, not only does it reduce the effective volume of the box due to its structure, but it is also impossible to freely control the depletion and temperature of the refrigerant, which increases the burden of running costs and the need to replace and clean the refrigerant during operation. Maintenance also required manpower.

The invention of this application uses a cooling device unit case that is compatible with the bottom plate of the box, so that it can be used in place of the bottom plate of the box during the winter when cold storage is not required.
Furthermore, it is possible to form a forced air circulation circuit and to freely control the selection and maintenance of an appropriate temperature for the article. or,
Since the joining means of the assembled joints of each plate can be performed in one operation, it is easy to disassemble and store when not in use, and this improvement contributes to labor saving during operation.

An embodiment of this invention will be described below with reference to the drawings.

A front door 1 consisting of a hollow panel P made of colored steel plate sandwiched and filled with a lightweight heat insulating material D such as polyurethane foam, left and right side panels 2 and 3, a back panel 4, and a top panel 5 having a rain shield projecting like an eave. , a vertically long box B is constructed by assembling a bottom plate 6 which is compatible with a cooling device unit case C to be described later. In box B, except for door 1, each board 2, 3,
4, 5, and 6 are assembled, the joint surface of the heat insulating material D is engaged with the unevenness, as shown in FIG. The box is tightly fastened at multiple points using connecting metal fittings, and the joining joints of each plate are appropriately filled with silicone sealer 9 to enhance airtightness and weather resistance. A packing 10 containing magnetic rubber is placed around the periphery of the back surface of the door 1 facing the opening of the box, and the door is hermetically closed with a hinge and a latch.
In place of the bottom plate 6, a compatible cooling device unit case C is airtightly connected to the box B via packing 12 provided around the four peripheries of the upper surface of the case 11. vessel 14
and a cold air fan 15, a cold air outlet 17 which is a part of the lid 21 of the case 11 and has a cold air duct 16 erected at the back of the upper part of the fan 15, and an inlet on the other side at a symmetrical position. 18 is opened to form a forced cold air circulation circuit, and a thermostat lens 19 is provided on the side wall of the case 11 to form a cold storage box. 20 in the diagram
is a shelf for pallets that can be installed and removed inside the box B.

With the above configuration, when assembling the back plate 4
After connecting both side plates 2 and 3 to the top plate 5 and cooling unit case C, the cold storage box is completed by attaching the door 1.
Precooling operation can be performed in a timely manner by turning on electricity via a timer. The temperature inside the box can be controlled to be weakly cooled, medium cooled, or strongly cooled by the thermostat 19 depending on the daily items. In this case, the refrigerator 13, cooler 14, cold air fan 15
The cold air is forcibly blown up from the duct 16, rises from the back panel 4 of the box toward the top plate 5, reverses, descends along the door, and is sucked into the cold air suction port 18, creating a convection of cold air. A circulation circuit is formed. When daily items are loaded into a box during delivery, they are kept cool by convection cold air and maintained at the required temperature until they are taken out. After the items are taken out, they are left unattended until the next operation is started by turning off the electricity.

Unlike cold storage boxes, which use cold storage agents and use cold air to fall from the top, there is no wasteful consumption of cold storage agents, no need for temperature control, and no need to consider the reduction in cold storage volume. The upper load of the cool storage agent is also avoided. Therefore, the cold storage box of this invention starts the specified operation at the appropriate time without requiring manual operation, is pre-cooled to the set temperature, and continues to be cooled at that temperature even after the goods are brought in.
After transporting the goods, all you have to do is set the timer for the next scheduled operation time, which is extremely efficient and requires no special consideration or manpower.The center of gravity is stabilized by installing the cooling unit case at the bottom, reducing the risk of tipping over. There is no need to control temperature and operation in response to changes in temperature, and it has excellent weather resistance, allowing for extremely safe and stable operation. It also has the effect of allowing the cooling device unit case to be opened and a bottom plate to be attached when there is no need for cold storage, such as during the harsh winter months. Furthermore, this box has excellent weather resistance and can be placed outdoors without worrying about the harmful effects of rain, dew, strong winds, or drought, or the intrusion of dust, so after taking out daily items, you can use it as a refrigerated storage space and display it in a show case. It can also be used as a storage space for frozen products in case of unavailability.

Furthermore, according to the configuration of the present invention, when the cold storage box and the cooling device unit case are combined, the bottom plate of the cold storage box is removed and the cooling device unit case is attached. There is no need for alignment at all, and the workability is extremely high.
