Abstract

<P>PROBLEM TO BE SOLVED: To secure a cold air circulation passage not disturbed by stored articles and to reduce costs without reducing effective inner volume in a storage. <P>SOLUTION: In this cold storage wherein a cooling unit (refrigerating machine) 2 is loaded on a top portion of a main body cabinet 1 as a heat insulating housing with a front door 3, and the cold air is circulated and distributed to a storage compartment 4 inside of the storage through the cooling unit to keep the stored articles 5 in cold, the heat insulating housing is composed of heat insulating walls 6 obtained by filling a heat insulating material 6c between an outer panel 6a and an inner panel 6b, and the inner panels of the heat insulating walls of at least right and left faces and a back face of the heat insulating housing are composed of corrugated panels on which projecting and recessed beam-shape vertically extends along the air distributing direction of the inside cold air, thus a clearance g as a cold air passage can be secured with respect to the stored article by the recessed groove shape of the corrugated panel to uniformly keep the stored articles in cold in the whole area of the storage, even when the stacked stored articles 5 collapse and lean to an inside wall surface. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a cool box applied to cool agricultural products such as rice and vegetables, and more particularly to the structure of the heat insulating casing.

As the agricultural product cooler described above, a cooler having a configuration in which a cooling unit (refrigerator) is mounted on the top of a cabinet that becomes a heat-insulating housing with a door on the front surface is known (for example, see Patent Document 1). The conventional configuration is shown in FIG.
2 (a) and 2 (b), 1 is a main body cabinet that becomes a box-shaped heat-insulating housing with an open front, 2 is a cooling unit (refrigerator) installed at the top of the main body cabinet 1, and 3 is the front surface of the main body cabinet 1. A double-speech door 4 is a storage room in the cabinet. In the storage room 4, stored items 5 (for example, rice packed in a bag) are stacked and stored and stored as shown. Moreover, the heat insulation housing | casing of the main body cabinet 1 is comprised by the heat insulation wall 6 of the structure which filled the heat insulating material (foam resin, such as urethane) between the panel (product made from a steel plate) in the upper and lower sides, right and left, and the back. .
During the cold storage operation in the cool box having the above-described configuration, the cool air cooled by the evaporator of the refrigerator built in the cooling unit 2 is circulated and blown toward the storage room 4 in the cabinet 1 of the main body cabinet 1 to cool the stored product 5. To do.

In this case, when a large amount of stored products 5 are stacked and stored in the storage chamber 4, the stored products 5 block the cool air ventilation path in the warehouse due to the rubbing and inhibit the circulating circulation of the cold air. May not be kept cold (uneven cooling). Therefore, in the conventional cool box, the post (beam material) 7 as shown in the figure is provided at appropriate intervals on the left and right side surfaces and the back side of the inside of the main body cabinet 1 at an appropriate interval. Even when the stored item 5 is laid on the inner bottom and stacked and stored in the warehouse, the gap 7 is formed between the inner wall surface of the heat insulating wall 6 and the stored item 5 by the post 7 and the insulator 8. It is ensured to maintain the circulation of cool air throughout the chamber.

However, the conventional storage shown in FIG. 2 has the following problems.
(1) Since the post 7 additionally equipped on the wall surface of the heat insulating casing is pushed out toward the inner side of the cabinet, the effective inner volume of the cool box is restricted.
(2) If the arrangement interval of the posts 7 is large, the bag-packed storage product with a small internal capacity is not restrained by the posts 7 and is directly displaced to the wall surface of the heat insulating housing by rubbing against the load, thereby forming a cooling air circulation ventilation path. May block.
(3) Further, if the arrangement pitch of the posts 7 is reduced, the number of posts installed and the number of assembly steps are increased accordingly, which increases the manufacturing cost.
The present invention has been made in view of the above points, and its object is to solve the above-mentioned problems and to reduce the effective internal volume of the warehouse, and to cool air circulation ventilation that is not hindered by stored items in the warehouse. The purpose is to provide an improved cool box that secures roads and can reduce costs compared to conventional structures.

In order to achieve the above object, according to the present invention, a cooling unit is mounted on a main body cabinet that is a heat insulating housing with a door on the front surface, and cold air is circulated through the cooling unit into a storage chamber of the main body cabinet. It is a cold storage that cools stored items stored in the storage chamber by blowing air, and the heat insulating housing is composed of a heat insulating wall filled with a heat insulating material between the outer panel and the inner panel.
At least the left and right and rear heat insulation walls of the heat insulation housing, the inner panel is constituted by a corrugated panel having a corrugated cross section (Claim 1), and as a specific aspect, a main body on which the cooling unit is mounted on the top For the cabinet, the inner panel of the heat insulating wall constituting the heat insulating casing is formed of a corrugated panel in which the uneven beam shape extends vertically along the direction of ventilation of the cool air inside the cabinet.

By adopting a corrugated panel as the inner panel of the heat insulation wall as described above, it is not necessary to rush into the inside of the cabinet of the main body cabinet and add multiple posts (beams) as before, and in the warehouse Regardless of the shape and size of stored items to be stored, the concave surface of the corrugated panel can be used as a wind guide path to secure a cold air passage in the entire interior of the box, and the stored items can be kept cool without uneven cooling.
In addition, the effective internal volume in the storage for storing the stored items can be increased as compared with the conventional structure in which posts are laid on the inner wall surface, and the number of assembling steps can be reduced to reduce the manufacturing cost.

Hereinafter, embodiments of the present invention will be described based on the examples shown in FIGS. In addition, Fig.1 (a) is the front view in the store | warehouse | chamber of the cold storage which removed the door, FIG.1 (b) is arrow XX sectional drawing in (a), FIG.1 (c) is an expanded sectional view of a heat insulation wall. In the drawing of the embodiment, members corresponding to those in FIG.
That is, in the illustrated embodiment, the heat insulating wall 6 constituting the heat insulating casing of the cabinet body 1 is made of a flat steel plate outer panel 6a and a corrugated panel 6b having a corrugated cross section as shown in FIG. It consists of a heat insulating material (foamed resin) 6c filled between the inner panel and the outer panel 6a and the corrugated panel 6b. Here, the corrugated panel 6b is formed such that the concavo-convex beam shape extends upward and downward along the cold air flow direction indicated by the arrow in FIG. It is set to be shorter than the outer size of the stored product 5.

  With the above configuration, in the storage state in which the storage items 5 are stacked and stored in the storage chamber of the main body cabinet 1, the storage items 5 rubbed as shown in FIGS. 1B and 1C are applied to the inner wall surface of the heat insulating casing. Even when it is offset, a gap g is secured between the stored product 5 and the corrugated panel 6b of the heat insulating wall 6 by a corrugated groove extending in the vertical direction. Can be circulated.
