Description

[Detailed description of the invention] The present invention relates to a freezing/refrigerating case, in particular, a machine room containing a built-in cooling device and a cooling room surrounded by a transparent plate such as glass, which is divided vertically or horizontally, and the front side of the cooling room is divided into two parts. This invention relates to a freezing/refrigerating case in which at least one of the top surface and the back surface is a sliding door made of two transparent plates.

As an example of this type of case, FIG. 1 shows a horizontal freezing/refrigerating case.

This show case 1 has a machine room 11 on the side that houses a cooling device consisting of a refrigerant compressor, a condenser, etc.
is formed, and four frames 1 are attached to the corners of this machine room 11 so as to extend in the length direction.
2, 13, 14, and 15 are used to form a cooling chamber 16 for frozen or refrigerated products. This cooling chamber 16 is provided with glass plates 18 and 19 (the side glass is not shown) on the front, top and side surfaces, except for a bottom wall 17 made of a heat insulator, and a sliding door made of two glass plates 20 and 21 on the back. is provided and formed. Each glass plate is attached to a sash integrated into each frame so that cold air does not leak. 22 is a partition having a cold air outlet through which a refrigerant evaporator passes, and 23 is a display shelf.

By the way, since each frame of conventional show cases is made of metal such as aluminum, condensation tends to occur, which poses problems in terms of use and service. Furthermore, the side glass is attached via the side frame 24, which prevents the display effect from being degraded by creating a blind spot in the display space 16, for example.

The present invention aims to provide a freezing/refrigerating case that eliminates these drawbacks.

The present invention is characterized by a frame that is attached using a part of a machine room and forms a cooling space in combination with a glass plate, and this will be explained below with reference to the drawings.

FIG. 2 shows an exploded view of an embodiment in which the present invention is applied to a horizontal freezing/refrigerating case.

In this case 1, as in the conventional case, a partition wall 22 made of a heat insulating material is erected on a bottom wall 17 made of a heat insulating material covered with a decorative board, and the machine room 11 and the cooling room 16 are partitioned by this partition wall 22. This partition wall 22
A cold air circulation circuit is formed in which the air in the cooling chamber 16 is sucked in by a motor fan (not shown) and then blown out into the cooling chamber 16 again through a refrigerant evaporator (not shown). Machine room 11
A refrigerant compressor 25, a condenser 26, etc. are arranged inside. In addition, the machine room 11 has a bottom wall 17, a partition wall 2
2, it is covered with a front panel 27, a ceiling panel 28, a rear panel 29, and a side panel 30. Note that each panel is screwed to a frame 31 that forms the framework of the machine room 11.

Next, one of the features of the present invention is a frame 32 provided at a corner extending in the length direction on the ceiling side.
33 will be explained with reference to FIG.

FIG. 3 is a partial sectional view taken along the line A--A in FIG. 2, with the partition wall 22 removed.

The frames 32 and 33 are each integrally molded from a resin material and have the same shape, so only one will be described. The frame body 32 has a generally fan-shaped cross section, and two end faces in the length direction that are substantially perpendicular to each other are provided with notches 321 and 322 in the length direction, respectively, and the frame body facing the notches has a different level. Board material 32
3,324 are provided. As a result,
Different level grooves 325 and 326 are formed by a deep groove and a shallow groove with the notch as an entrance. In addition, a cylindrical portion 327 is provided in the longitudinal direction in a portion near the key point of the sector, and a portion in the longitudinal direction, specifically, a second cylindrical portion 327 is provided in the longitudinal direction.
Referring to the figure, a flange 328 is attached to a portion of the machine room 11 corresponding to the mounting portion 311 of the frame 31.
is provided. The flange 328 extends horizontally when the frame body 32 is attached to the frame 31, and can be fixed with the screw 34 between the flange 328 and the attachment portion 311.

By using a frame body having such uneven grooves, as for the frame body 32, the horizontal uneven grooves 325 are filled with glass having different thicknesses as shown by solid lines and two-dot chain lines in FIG. A board can be inserted. In addition, by fitting glass plates into the deep grooves and the shallow grooves, both glass plates can be slid in the length direction, thereby forming a sliding door. In the vertical groove 326,
The front glass plate 18 is fitted with a slight inclination.

The frame 33 is the same as the frame 32,
Here, the ceiling glass plate 19 is fitted into the horizontal uneven groove 335, and the vertical uneven groove 336 is fitted into the ceiling glass plate 19.
As described above, sliding doors made of glass plates 20 and 21 of the same thickness are fitted into the deep groove and the shallow groove, respectively.

Referring again to FIG. 2, regarding the lower receiving portions of the front glass plate 18 and the glass plates 20, 21, each glass plate is attached to a lower frame body 34, 35 molded from a resin material in a similar shape to the conventional one. It is sufficient to use one that has grooves in the length direction that allow for sliding.

For assembly, the frames 32 and 33 are screwed to each mounting portion 311 (the rear side is not shown), and then the panels 27, 28, 29, and 30 are screwed to form the machine room 11. Next, the glass plate 18 is fitted into the longitudinal groove of the frame 32 and the groove of the frame 34 by sliding it from the side end. Similarly, the ceiling glass plate 19 is set. A frame 36 having a groove corresponding to the groove provided in the frame 35 is integrally erected at the end of the frame 35 opposite to the machine room 11.
For this reason, the sliding door glass plates 20 and 21 are fitted in the same manner as in the fitting of shoji or fusuma sliding doors, by fitting the upper edge of the glass plate into the groove of the frame 33 and then fitting the lower edge into the groove of the frame 35. is taken.

After each glass plate is fitted into the groove of each frame in this way, a side glass plate 37 is placed on the side of the cooling chamber 16.
can be installed. The glass plate 37 is attached with screws, and the upper side of the glass plate 37 is attached to the frame 3.
Female threads are cut in the holes at the ends of the cylindrical parts 327, 337 (see FIG. 3) of 2 and 33, and on the lower side, the ends of the bottom wall 17 or the frames 34, 3
By providing a screw hole at the end of 5,
The glass plate 37 includes the bottom wall 17 and the frames 32, 33, 3
4, 35 and the ends of the frame 36 in close contact. Note that at both ends of the front glass plate 18 and the ceiling glass plate 19, that is, at the contact portions with the partition wall 22 and the side glass plate 37, there is a cross section for sealing, except for the portions that fit into the grooves of each frame. A U-shaped gasket 38 (see FIG. 3) is attached. The same applies to the glass plates 20 and 21.
Note that 39 is a hanging rod for hanging the shelf board.

By the way, in such a frame, when a sliding door is constructed from two glass plates, the height of the glass plate fitted into the deep groove of the stepped groove must be larger than that of the glass plate fitted into the shallow groove.
Moreover, since there is nothing intervening between the two glass plates, the two glass plates are slid in a state close to surface contact, which is undesirable.

The present invention solves these problems, and will be explained below.

FIG. 4 shows an embodiment of the present invention in which a sliding door is provided on the back side of the show case, and shows the same portion as FIG. 3.

Vertical step groove 3 in the frame 33 on the back side
Inside 36 is a rectangular board 4 having the same length as the frame 33.
0 is inserted. This substrate 40 has notches 33 at both edges of the opening in the length direction of the stepped groove 336.
Since it is hung on the flange forming part 2, there is no need for screwing, gluing, etc. Further, the board 40 is provided with holes for screwing at intervals in the length direction, so that the screws 3
4', the rail substrate 41 is attached so that the flange at the opening edge of the stepped groove 336 is sandwiched between the substrate 40 and the rail substrate 41.

The rail board 41 includes a mounting plate 411 to the board 40 having the same length as the frame body 33, and glass plates 20, 21.
It is formed by integrally molding plates 414a, 414b, and 414c, which form grooves 412 and 413 for guiding the slides, from a resin material. and mounting plate 411
A screw hole is provided in the substrate 40 so as to correspond to a screw hole in the substrate 40 .

The depths of the grooves 412 and 413 are determined to provide sufficient space between the grooves 412 and 413 and the upper ends of the fitted glass plates, taking into account the above-mentioned fitting operation of the glass plates 20 and 21. Also, the glass plates 20, 2
1 in the front-to-back relationship shown in Figure 2, groove 4
A rectangular soft resin material (not shown) is press-fitted into the end of the groove 412 on the machine room side and the end of the groove 412 on the side glass plate side, respectively. This is to soften the impact on the edge of one glass plate when it is completely opened, and to create a portion of the two glass plates on the opposite side that do not overlap with each other. This prevents the glass plate from breaking, and when closing the opened glass plate again, the end of the glass plate to be closed can be easily grasped with fingers and slid in the closing direction. Furthermore, a flange is formed at the tip of each plate 414a, 414b, 414c forming the grooves 412, 413, respectively. As shown in FIG. 4, this flange serves to insert a plate 42 having an L-shaped cross section into a groove 412 in a portion corresponding to the rear panel 29 of the machine room without screwing or mounting. That is, through holes are provided in the plate 414c corresponding to the screw-fastening locations of the back panel 29, and screw holes are provided in the plate 42 to be used when attaching the back panel 29.

In FIG. 4, reference numeral 41' denotes a rail substrate that is provided on the frame 35 in FIG. 2 and receives the lower sides of the glass plates 20, 21.

Of course, the substrate 40 and the rail substrate 41 are not limited to the shapes shown in the drawings, and the substrate 40 may have an L-shaped cross section. Rail board 41
The same effect as in the embodiment can be obtained even when the plate 414b has no flange at the tip, like the lower rail board 41' shown in FIG. A cross-sectional shape that omits the flange at the tip is fine.

As described above, in the present invention, by using a frame body having a generally fan-shaped cross section and having uneven grooves on the two end faces, and a rail board combined with this frame body, two glass plates of the same size can be used. In addition to being able to form a sliding door and allowing the glass plates to slide with a slight gap between them, the following effects can be obtained.

Since the frame body and the rail board are molded products made of extremely fat material, it is possible to prevent dew condensation from forming on these parts.

The rail board can be combined with either the vertical or horizontal uneven grooves in the frame. For example, in Fig. 4, by attaching the rail substrate to the horizontal uneven grooves of the frames 32 and 33, the ceiling surface can be It can be used as a case with a sliding door, and can also be made into a case with a front sliding door.

By reducing the number of parts, it is possible to improve workability and reduce costs.

As mentioned above, by press-fitting a soft resin material into the end of the predetermined groove of the rail board 41, it functions as a stopper when opening and closing the sliding glass plate, and
It is possible to prevent the glass plate from breaking due to a collision between the edges of the glass plate.

By inserting a plate into the outer groove of the rail board corresponding to the machine room, the rail board can be used for attaching a back panel for forming the machine room.

By giving the frame multiple functions as described above, the front, top and back surfaces of the show case can be freely selected from combinations such as double-glazed glass, single-paned glass, and even sliding doors.

Note that the present invention is not limited to the horizontal freezing/refrigerating case shown in the embodiment, but can also be applied to a vertical freezing/refrigerating case. In other words, in the case of this show case, a machine room is configured at the bottom of the show case, and a cooling room is formed by a glass plate through frames extending upward from the four corners of the machine room. The frame body according to the present invention is used, and a rail board is combined with the frame body at the ceiling and bottom of the surface to be used as a sliding door. It goes without saying that a transparent plate made of acrylic resin or the like may be used instead of each glass plate.
