Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a bottom structure of a display room in a refrigerated showcase. 2. Description of the Related Art Conventionally, as an example of this type of refrigerated showcase, a spilled display case installed in a sushi restaurant or the like is known. As shown in FIG. 9, the display case is provided with a display room c having a heat insulating structure and a double glazing b extending from the front surface to the upper surface on the upper surface side of a machine room a equipped with a refrigerating device. The cold air generated by the above-mentioned refrigerating apparatus flows through the cool air passages d and e (the left and right sides are not shown) provided in a circulating manner over the upper, lower, left and right side surfaces of the chamber c, so that the inside of the display room c is indirect. Cooled. Bottom n of display room c
Is slightly inclined forward, and a drain port f is opened at one side of the front end, and is led out of the machine by a drain hose g. Further, a slide door i is arranged at an entrance h opened on the rear surface of the display room c, and the lower rail j is installed so as to be below the bottom surface n of the display room c in order to increase the opening area of the entrance h. ing. During operation, a drain k is plugged into the drain port f, a snowboard m is placed on the bottom surface n of the display room c, and the sushi naga is put in and out of the snowboard m while opening and closing the slide door i. . [0003] Incidentally, in the case of the above-mentioned display case, the bottom surface n of the display room c is particularly liable to be soiled, so that it is necessary to appropriately clean it. As a washing method, after removing the mushroom m, water is poured with a hose or the like with the drain port f kept in the stopper k, and the water is stored using the slope of the bottom surface n, and rubbed and washed with a sponge or the like. In many cases, the tap k is removed and drained. In the case where the above-described cleaning method is adopted, when the water is scrubbed with a sponge, the stored water is wavy and overflows on the lower rail j of the slide door i. As shown in FIG. 10, an auxiliary drain port o is opened in a part of the outer wall to join with the above-mentioned drain hose g so as to be convenient for cleaning the lower rail j. j
The water that has overflowed is drained through a drain hose g. However, since the amount of drainage from the lower rail j is limited to a small amount, if large sprinkles are generated one after another due to the sponge washing as described above and overflow to the lower rail j, the drainage from the lower rail j cannot be made in time, Eventually, the result is that the air overflows the lower rail j and out of the machine. However, if the inclination of the bottom surface n of the display room c is steep, the overflow of water as described above can be improved. However, not only is it difficult to place sushi and the like, but also the opening area of the entrance h becomes smaller. Alternatively, it has been difficult to adopt it to increase the height of the product, and no effective solution has been found. The present invention has been completed based on the above-described circumstances, and an object of the present invention is to effectively prevent overflow of water to the outside of a machine during indoor cleaning. [0005] As means for achieving the above object, the invention of claim 1 has a display room for foodstuffs and the like inside, and a slide door is provided on a side surface of the display room. Ru is arranged
At the same time, a draining member such as a snowboard is provided on the bottom of the display room.
In the refrigerated showcase in which is provided, a rising portion is provided at an edge of the bottom surface of the display room on the side where the slide door is provided , and the rising portion of the rising portion is provided .
It is characterized in that the height is set to be equal to or less than the height of the draining member . <Effects and Effects of the Invention><Invention of claim 1> Even if the water stretched in the display room is wavy, the rising portion functions as a weir to prevent overflow from the outside of the machine. Regulate . When arranging the drainage member to the bottom surface of Chen column chamber, but the height of becomes dead space, so the rising portion will be provided by utilizing the dead space,
The wave stopping effect can be expected without reducing the effective aperture.

A circulating cool air passage is formed by connecting the lower passage 24, the side passage 25B, the upper passage 26, and the side passage 25A. As shown in FIG. 2, the lower surface of the upper passage 26 is provided so as to have a slightly downward slope toward the rear surface, and a dew receptacle 29 is provided at the rear edge of the lower surface. On the back side of the display room 2, as shown in FIG. 1, a back plate 31 is provided only behind the above-mentioned portion of the bottom plate 21 on which the high-order surface 22 is provided. The opening 8 described above is formed toward the side. The opening 8 is divided right and left by a partition frame 32 to form two entrances 33, and each entrance 33 is provided with a slide door 35. This sliding door 35
Is composed of upper and lower rails 36 and 37 and a pair of glass doors 38. Specifically, as shown in FIG. 2, an upper rail 36 and a lower rail 37 each having a channel shape are attached to the upper edge and the lower edge of the entrance 33 so as to face each other. One long rail is attached to each of the rails 37 so as to be shared by the left and right entrances 33. A partition plate 39 stands on the upper rail 36 at the center in the width direction. On the other hand, the lower rail 37 is left without a partition and is provided at a position lower than the bottom plate 21 of the display room 2 described above. Each glass door 38 has an upper rail 3 on the upper edge side.
6 is individually fitted on both sides of the partition plate 39, and the lower edge side is fitted in the lower rail 37 in a state of being in contact with each other, and is mounted in a pulling manner. At the front edge of the left end of the bottom plate 21 of the display room 2 as viewed from the front, a drain 41 is opened as shown in FIG. 2, and a lower end of a drain pipe 42 connected to the drain 41 is provided. A hose 43 that penetrates through the heat insulating plate 18 and protrudes into the machine room 3 and is connected to the lower end of the drain pipe 42 is guided outside from the back surface across the inside of the machine room 3. The drain 41 is provided with a removable stopper 44. Also,
As shown in FIG. 5, an auxiliary drain port 45 is opened at a predetermined position on the outer wall 37A of the lower rail 37, and an auxiliary drain pipe 46 is provided so as to correspond to the outside of the auxiliary drain port 45.
And is joined to the hose 43 described above. The edge of the bottom plate 21 of the display room 2 on the side of the opening 8 has a rising portion 5 having a mountain shape in cross section.
0 is provided. As shown in detail in FIG. 5, the rising portion 50 is formed integrally with the bottom plate 21 by bending an edge of the bottom plate 21, and the inner surface is gradually formed from the room toward the outside of the room. The inclined surface 51 has a gentle up slope. On the other hand, the outer surface becomes a steeply inclined surface and extends further below the bottom plate 21, and the insertion portion 52 bent outward is formed below the groove bottom of the lower rail 37. It is inserted into the insertion groove 53 and is fixed in close contact with the inner wall 37B of the lower rail 37. Further, as shown in FIG. 2, the height of the rising portion 50 is set slightly lower than the height of the snowboard 28 placed on the bottom plate 21 of the display room 2. The first embodiment has the above structure, and its operation will be described below. During operation, the drain port 41 is plugged to prevent cold air from leaking.
A snowboard 28 is placed on the bottom plate 21. When the refrigerating device and the cooling fan 15 are driven, as shown by an arrow in FIG. 3, the air sucked by the cooling fan 15 passes through the cooler 12 to generate cool air, and the cool air is generated in the lower passage. 24, the side passage 25B, the upper passage 26, and the side passage 25A, circulates around the display room 2 and is again sucked into the cooler 12 side, so that the inside of the display room 2 is indirect. Cooled. Then, while the slide door 35 is opened and closed, sushi noodles and the like are put in and out of the snowboard 28 in the display room 2. During this time, the juice and shards from the sushi noodles are likely to fall and adhere to the bottom plate 21 of the display room 2, so that it is necessary to appropriately wash them. As an example of cleaning, the glass door 38 of the slide door 35 is removed and the saw blade 28 is taken out, while the plug 44 of the drain port 41 is left open.
As shown by the dashed line, water W is put into the display room 2 from the hose X, and the water is stored using the inclination of the bottom plate 21. Then, as shown in FIG. 4, as shown in FIG. 4, scrubbing is performed using a sponge Y or the like, and finally, the plug 44 is removed, and waste and wastewater are discharged from the drain port 41, whereby efficient cleaning can be performed. When the sponge Y is used for scrubbing as described above, the water W stretched in the display room 2 is wavy, but the bottom plate 2
Since the rising edge 50 is provided at the edge of the opening 8 on the side of the opening 1, the rising portion 50 functions as a dam weir, as shown in FIG. 5, and is prevented from overflowing to the lower rail 37 side. You. Even if it overflows to the lower rail 37 side, it is slightly stopped, so that it is quickly discharged from the auxiliary drain port 45 of the lower rail 37 and a large amount of water is prevented from being accumulated in the lower rail 37, so that the airplane may go out of the machine. Water is prevented from overflowing. As another cleaning method, a plug 44 of the drain port 41 is used.
While water is continuously supplied from the hose X in an amount larger than the drainage amount, and the sponge Y is stored while storing the water W at the same time as the drainage.
In some cases, rubbing may be performed. In this case as well, the accumulated water W undulates, but similarly, the rising portion 50 functions as a weir to prevent water from overflowing outside the machine. There is a concern that the provision of the rising portion 50 may reduce the opening area of the rear surface. However, in use, the snowboard 28 is placed on the bottom plate 21 of the display room 2, and the rising portion 50 is set lower than the snowboard 28. The 50 does not get in the way and does not substantially reduce the open area during use. In use, for example, when taking out the sushi noodles, the snowboard 28 is shifted rearward together with the entrance 33.
If it protrudes from the sliding door 35, the sliding door 35 may not be able to be closed. However, the provision of the rising portion 50 prevents the snowboard 28 from shifting backward. Further, since the inner surface of the rising portion 50 is formed as a gentle slope 51, for example, when a solid material such as a large food material falls on the bottom plate 21 of the display room 2 and the solid material such as food is removed, a cloth width or the like is used. It can be easily swept out using the inclined surface 51. <Second Embodiment> Another embodiment in which the arrangement of the rising portion is changed will be described below. FIG. 6 shows a second embodiment of the present invention. In the second embodiment, the rising portion 55 is provided as a separate component from the bottom plate 21 of the display room 2. The rising portion 55 has a gentle inclined surface 56 on the inner surface side and a steep inclined surface 57 on the outer surface side.
The bottom plate 21 is formed by fitting a mounting portion 58, which is formed in a cross-section mountain shape slightly shorter than the snowboard 28 and protruded at an appropriate position in the longitudinal direction of the bottom surface, into a mounting hole 59 of the bottom plate 21. It is attached along the edge on the opening 8 side.
The same operation and effects as those of the first embodiment can be obtained. <Third Embodiment> FIG. 7 shows a third embodiment of the present invention. In the third embodiment, the rising edge 60 is formed by extending the upper edge of the inner wall 37B of the lower rail 37 upward and bending the extended portion as a gentle inclined surface 61 toward the bottom plate 21. . The rising portion 60 is also formed to be slightly shorter than the snowboard 28. The same operation and effect as in the first embodiment can be obtained. <Fourth Embodiment> FIG. 8 shows a fourth embodiment of the present invention. In the first embodiment, the rising portion 50
Is a straight slope 51, whereas in the rising portion 65 of the fourth embodiment, the inner face is formed as a curved slope 66. The same operation and effect as in the first embodiment can be obtained. <Other Embodiments> The present invention is not limited to the embodiments described above and illustrated in the drawings. For example, the following embodiments are also included in the technical scope of the present invention. In addition, various changes can be made without departing from the scope of the invention. (1) The present invention can be similarly applied to a display case in which a refrigerating device is provided on a side surface of a display room. (2) Further, the present invention can be widely applied not only to the display case of sushi nata, but also to other general refrigerated showcases that refrigerate while displaying ingredients and the like.
