Description

[Detailed Description of the Invention] The present invention relates to a show case, and more particularly, to an improvement of a heat insulating panel of the show case body.

As shown in Fig. 1, this type of case, such as a vertical type case, is divided into two upper and lower chambers. The case body 1 shown in FIG. 1 has side panels 3, 3 and a back panel 4, as shown in FIGS. 2 and 3. It is made by assembling via screws 5. The side panel 3 has an inner panel 6 and an outer panel 7 connected together via a structural member 8 made of wood arranged along the side edge, and a space formed between the inner panel 6 and the outer panel 7. It is made by injecting urethane resin 9. Further, the back panel 4 is also made in the same manner as the side panel, but the shape of the structural member 8 located on the back panel side of the side panel 3 is slightly different.

However, in order to assemble the case body 1 in a conventional vertical case, as shown in FIG. This is done by connecting the two from the outside with screws 5, but in this case, since the structural members 8, 8 provided on the side panels of the case body 1 are exposed to the outside, the cover metal fittings 11 are separately attached. established,
It is necessary to cover the exposed parts. Furthermore, since the mounting position of the screw 5 is also visible from the outside, it is necessary to provide the cap 12 at this location as well.

Furthermore, during use, the structural material 8 causes dew to form on the surface of the outer panel 7 due to heat conduction of the inner panel 6 and conduction of cold air inside the refrigerator, so an anti-condensation heater 13 is attached to prevent this. There is a need. In addition, the structural material 8 absorbing moisture may cause corrosion.

This idea was made in view of the above points,
The purpose of the present invention is to provide a case that reduces the number of component parts, prevents dew from forming on the outer panel, and is lightweight and easy to work with.

The purpose of the present invention is to construct a side panel consisting of a box-shaped outer panel, an inner panel that covers the opening of the outer panel, and a heat insulating material filled between the outer panel and the inner panel, and which is in contact with the side panel. An L-shaped bracket is installed at the inner corner formed between the back panel and the rear panel, and one side of the L-shaped bracket is fixed to the structural member provided on the side panel, and the other side is fixed to the structural member provided on the back panel. This is achieved by using a case with

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

In FIG. 4, the same members as those in FIG. 2 are given the same reference numerals.

In Fig. 4, reference numeral 20 is a side panel of the main body of the refrigeration case, and 20 is a box-shaped metal plate whose peripheral edge is bent 90 degrees to one side and the bent end is bent 90 degrees inward. It is composed of an outer panel 21 made of plastic, an inner panel 22 for covering the opening of the outer panel 21, and a heat insulating material 23 made of foamed urethane resin that is filled in the space defined between the outer panel and the inner panel. A structural member 24 made of wood is arranged on the rear side of the space and at a distance from the end face toward the front side by the thickness of the back panel 4. As shown in FIG. 5, the structural member 24 is provided only at the mounting position of an L-shaped metal fitting 25 for joining the panels.

As shown in FIG. 6, the L-shaped fitting 25 is arranged at an inner corner formed at the joint between the side panel 20 and the back panel 4, and connects one side 25a to the side panel 20 via a screw 26. Screw 2 on the other side 25b
It is attached to the rear panel 4 via 6. Thereby, the side panel 20 and the back panel 4 are integrally coupled. The dimensions of the screw 26 are as follows:
The thickness is set to be smaller than the thickness of the outer plate 21, so that when the screw is screwed in, the tip of the screw does not protrude outside from the outer plate 21.

Further, a urethane block 27 which is a heat insulating material is interposed between the structural member 24 and the outer panel 21.
By adjusting the dimensions when foaming urethane, side panel 2
This prevents 0 from being deformed.

On the other hand, a gasket receiver 30 made of a material with poor thermal conductivity, such as plastic, is attached via screws to the periphery of the front opening of the show case body 1. By causing the magnet 32 to attract the door frame 33 of the door 2, the door 2 can be tightly closed. In this case, as shown in FIG. 8, the magnetic gasket 34 may be directly attached to the show case body through screws, or as shown in FIG. 9, a gasket receiver 35 may be fitted around the opening.

With this configuration, since no magnet is attached to the opening/closing door, the door frame can be set small, and the glass area becomes large.

Therefore, the filling operation with foamed urethane when assembling the case body can be performed with the side panels and the back panel connected to each other with the L-shaped metal fittings, so the urethane filling operation can be completed in one time.

In the above embodiment, the structural member 24 is made of wood, but it goes without saying that the same effect can be obtained by using an L-shaped member 40 made of plastic or metal as shown in FIG.

As mentioned above, according to the present invention, the strength is reinforced by the structure of the side panels, so unlike conventional ones, there is no need for as many structural materials, which reduces the amount of wood used and reduces the urethane work. It is easy to use, and it prevents dew from coming into contact with the wood and the outer panel.Furthermore, it eliminates the need for screw fixing caps and cover metal fittings, which were required with conventional products, making the appearance more streamlined. Since there is no need to install an upper dew-proof heater, the cost can be reduced.
