Abstract

(57) [Summary] [PROBLEMS] To store in a cold and hot storage, which is installed in a vehicle or the like and has a temperature control means for keeping the temperature inside the refrigerator constant and a means for switching between cold keeping operation and warm keeping operation in the refrigerator. Prevents the rolling of cans of soft drinks, etc., and prevents damage to the storage tray in the refrigerator. A plurality of first grooves parallel to one side surface of the tray and having an arc-shaped cross section are formed on the bottom surface of a tray for storing cold or heat-retaining articles, and the plurality of the plurality of grooves are formed. A second groove was formed which was orthogonal to the first groove and whose cross-sectional shape was an arc shape having a curvature different from that of the first groove. As a result, it is possible to prevent the two types of cans stored from rolling and prevent the tray from being damaged.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cold storage box installed in a vehicle or the like.

[0002]

2. Description of the Related Art FIG. 4 is a top view of the interior of a conventional vehicle cold / heat storage cabinet, and FIG. 5 is a vertical cross-sectional view of the same cold / hot storage cabinet. In the figure, 1 is a main body, 2 is a tray, 3 is a heat insulating material adhered to the back surface of the tray 2, 4 is a Peltier unit whose one surface is in contact with the tray 2, 10 is a cooling fan, 11 is a duct, and 12 is a switch. A switch, 13 is a console, and 15 is a lid.

A main body 1 installed in a console 13 in a vehicle compartment is equipped with a tray 2 for storing articles which is formed of a material having good thermal conductivity such as an aluminum plate material and keeps cold or warm. A heat insulating material 3 is adhesively attached to the entire surface for heat insulation. The heat insulating material 3 is not attached to a part of the wall surface on the back surface of the side surface of the tray 2, and the entire heat transfer surface of the Peltier unit 4 is attached in close contact with that portion.

The Peltier unit 4 performs electronic cooling and heating by utilizing the Peltier effect of a thermoelectric element, and the surface of the Peltier unit 4 which is in close contact with the side surface of the tray 2 serves as a heat absorbing or heating element. Due to the heat transfer through the side wall surface of the tray 2, the inside of the cold storage box formed by the tray 2 and the closed lid 15 is maintained in a cooled or heated state. By operating the changeover switch 12 installed in the main body 1, the inside of the refrigerator is switched to a cold or warm state, and a temperature sensor and a controller (not shown) control the temperature inside the refrigerator to keep it constant. A cooling fan 10 equipped with a duct 11 is installed on the surface of the Peltier unit 4 opposite to the surface in contact with the tray 2 in order to promote heat dissipation or heat absorption of the Peltier unit 4. In this type of cold storage, the floor surface of the tray 2 forming the interior has a flat shape, and is often used for keeping cold or warm of soft drinks and juices in a cylindrical metal container. ing.

[0005]

In the conventional cold and hot storage, since the floor surface of the tray for storing cold or heat insulating articles has a flat shape, the soft drinks and juices in the cylindrical container are provided. When it is stored, it cannot be stably stored in the storage, and especially when it is installed in the vehicle, the storage can rolls in the storage as the vehicle runs,
This causes problems such as damage to the tray wall surface.

The present invention is intended to solve the above-mentioned drawbacks of the prior art, to stably store the cans of the beverage so as not to roll, and to prevent the tray from being damaged.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems and includes a temperature control means installed in a vehicle or the like for keeping the temperature inside the refrigerator constant, and a cold keeping operation and a warm keeping operation in the refrigerator. In a cold / hot storage provided with a switch or the like means, a plurality of first grooves having a circular arc-shaped cross-section parallel to one side surface of the tray are provided on the bottom surface of the tray for storing the cold insulation or the article for keeping the heat. And a second groove which is orthogonal to the plurality of first grooves and whose cross-sectional shape has an arcuate shape having a curvature different from the arcuate curvature of the first groove. It is about the warehouse.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a top view of the interior of a vehicle cold / heat storage box according to an embodiment of the present invention, and FIG. 2 is A- in FIG.
A sectional view, FIG. 3 is a BB sectional view of FIG. In FIGS. 1 and 2, reference numeral 16 denotes a groove provided on the bottom surface of the tray 2 and having a bottom surface having an arc cross section. This groove is provided parallel to one side surface of the tray 2, and the cross-sectional shape of the bottom surface is adapted to the outer cross-sectional shape of a slightly large cylindrical metal can A of commercially available soft drinks and juices. A plurality of such grooves 16 are provided. 1 and FIG. 3, 1
Reference numeral 7 is a groove provided on the bottom surface of the tray 2 and having a bottom surface having an arc cross section. This groove is provided orthogonally to the groove 16, and the cross-sectional shape of the bottom surface is adapted to the outer cross-sectional shape of a slightly small cylindrical metal can B of commercially available soft drinks and juices. A plurality of such grooves 17 are provided.
The configuration of other parts is the same as that of the related art.

In the cold storage of this embodiment, rows of grooves having different radii of curvature are formed so as to be orthogonal to the cross section of two types of cylindrical metal cans for soft drinks which are orthogonal to each other on the bottom surface of the tray. Therefore, two types of cylindrical metal cans having different outer diameters can be sunk into the groove and stably stored with an appropriate gap. This prevents the metal cans from rolling within the tray and prevents damage to the tray.

[0010]

In the cold-storage cabinet of the present invention, a plurality of first trays having a circular arc-shaped cross-section parallel to one side surface of the tray are provided on the bottom surface of the tray in the cabinet for storing cold-keeping or heat-retaining articles. No. 2 is formed, and a second groove is formed which is orthogonal to the plurality of first grooves and has an arcuate cross-sectional shape different from the arcuate curvature of the first groove. It is possible to store various kinds of cans for soft drinks, etc., and it is possible to prevent rolling of these cans and prevent damage to the tray.
