DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal commercial storage generally referred to as an under counter, and more particularly to a storage provided with a storage container called a hotel pan on an upper surface thereof.

[0002]

2. Description of the Related Art Conventionally, this kind of refrigerator is known as Japanese Patent Publication No. 6-276.
As shown in Japanese Patent Publication No. 14 (F25D 23/12), a foamed heat insulating material is filled between a stainless steel inner box and an outer box, and a horizontally long rectangular opening is provided at the rear of the front surface and the top surface. And a machine room provided on the side of the heat-insulating box and accommodating the condensing unit, and a double-leafed door is provided to openably close the front opening.

Further, a heat-insulating protruding wall having an opening having substantially the same size as the top opening is provided on the heat-insulating box. This heat-insulating protruding wall is different from the heat-insulating box,
The connection between the two is performed by a plurality of L-shaped connection fittings and screws.

[0004]

The prior art described above is
Because the heat-insulating protruding wall body separate from the heat-insulating box is connected by screwing the L-shaped connection metal fitting with a screw, the connection tool and the screw etc. are exposed at the connection part, and the appearance is poor. was there. Further, the screw and the like are generally made of iron, and when dew condensation occurs on a portion where the screw is exposed, rust and the like are generated, which is a hygienic problem.

For this reason, it is necessary to use a non-rusting material such as stainless steel for the material of the screw, and there has been a problem that the cost is high. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has improved the appearance of a connection portion between a heat-insulating box and a storage portion (a heat-insulating protruding wall in the prior art), and improved hygiene at this portion. To provide a horizontal storage that aims to achieve the above at low cost.

[0006]

As a means for achieving the above object, a heat insulating material is provided between the inner and outer boxes, the heat insulating box having openings on the upper surface and the front surface, and a front surface of the heat insulating box. A heat-insulating door for opening and closing the opening and a storage port communicating with the upper surface opening of the heat-insulating box are formed, and a storage part separate from the heat-insulating box having a flange formed outward from the lower end. And a top table having an insertion opening through which the storage portion is inserted, and a top table for pressing a flange of the storage portion at a periphery of the insertion opening.

[0007]

According to the present invention, when the storage section is mounted on the heat insulating box, the flange of the storage section is held down by the top table, so that the connection can be made without using screws or the like at the connection portion. Can be maintained in a good appearance.

Reference numeral 10 denotes a pedestal supporting the heat-insulating box 1 and the machine room 8, and reference numeral 11 denotes a handle of the heat-insulating door 7.

Reference numeral 12 designates a cooler and a cooling air circulation fan which constitute a refrigeration cycle together with the condensing unit in the machine room 8.
Numeral 19 denotes a cooling air discharge duct provided on the top surface in the heat insulating box 1. Further, the cooling chamber 1
2, a cool air suction port 13 for sucking cool air in the storage room 2 is formed at a substantially middle portion and a lower portion, and a cover 14 formed to send cool air after heat exchange to the cool air discharge duct 19 is provided. ing. Reference numeral 15 denotes a net shelf on which stored items are placed, 16 denotes a guard provided so that the cold air inlet 13 of the cover 14 is not blocked by the stored items, 17 denotes an interior light for illuminating the inside of the storage room 2, Reference numeral 18 denotes a drainage device that drains defrost water generated from a cooler in the cooling chamber 12 and dew condensation water generated in the storage chamber 2.

Next, the main part of the present invention will be described. An upper surface opening 20 is formed on the upper surface of the heat insulating box 1 so as to face the cool air discharge duct 19. Reference numeral 29 denotes a resin breaker for connecting the inner box 3 and the outer box 4 of the upper surface opening 20. Reference numeral 21 denotes a top table provided on the upper surface of the horizontal storage, which forms a work table. An insertion port 22 is formed in the top table 21 at a position corresponding to the upper surface opening of the heat-insulating box 1. The insertion port 22 is formed so as to protrude upward through the insertion port 22, and is used for a container such as a hotel pan. Is stored in the storage section 23 for storing.

The storage section 23 is frame-shaped and has a storage port 28 communicating vertically. The storage portion 23 includes a frame-shaped outer plate 24 having a lower end flange 24A bent outward from the lower end and an upper end flange 24B bent inward from the upper end.
And an inner plate 25 made of resin (vinyl chloride), which is connected to the end of the upper end flange 24B of the inner plate 25 and is attached so as to form a space inside the outer plate 24, and is attached across the inner plate 25 and the outer plate 24. A heat insulating material 27 is inserted into a space formed by the outer plate 24, the inner plate 25, and the bottom plate 26. Here, the storage section 23 is foamed by a method referred to as a simple foaming method. Specifically, after the outer shell of the storage section 23 is assembled, the heat insulating material 27 is simply inserted. Note that the heat insulating material 27 used in this embodiment is a urethane heat insulating material, and the outer shell of the storage portion 23 is joined using an adhesive or a double-sided tape.

When the storage section 23 is mounted on the heat-insulating box 1, the storage section 23 assembled with the upper opening 20 of the heat-insulating box 1 is placed. At this time, the inner plate 2 of the storage section 23
5 is formed so as to protrude downward and to be located in the upper surface opening 20 of the heat-insulating box 1, and the joint portion between the heat-insulating box 1 and the storage portion 23 is hidden by the inner plate 25. . After the storage section 23 is placed, the top table 21 is mounted on the heat-insulating box 1, whereby the flange 23 </ b> A of the storage section 23 is pressed at the periphery of the insertion opening 22 of the top table 21, and the mounting is completed. Becomes

FIGS. 5 to 8 show the storage section 2 described above.
5 shows a state in which the upper end face is horizontal, and FIG. 6 shows a storage part in which the upper end face is inclined forward behind the storage part 23 in which the upper end face is horizontal. 23 is provided. FIG. 7 shows a storage portion 23 having an upper end surface inclined forward, and FIG. 8 shows a similar form, but a mounting portion 30 for mounting the flange of the hotel pan is notched inside. Configuration.

[0015]

As described above, since the flange of the storage section is pressed by the periphery of the insertion opening of the top table, the heat-insulating box and the storage section are connected, and the connection portion is also formed by the inner plate. Because it is hidden, it has an aesthetic configuration. Furthermore, since the inside is made of a resin plate without using a connection fitting or a screw, the generation of rust or the like can be prevented, and a hygienic horizontal storage can be provided at low cost.
