2. Description of the Related Art Insulated showcases such as frozen showcases and refrigerated showcases are widely used for selling frozen foods, ice creams, and low-temperature storage foods such as chilled foods, dairy products, and alcoholic beverages. Has been
Normally, the temperature inside the refrigerator is also set so as to maintain -5 to -30C, and the temperature difference between the outside air temperature which is 5 to 35C is large.

[0003] By the way, this kind of cold storage showcase is
A case body portion formed with a storage space for low-temperature stored food in the refrigerator, and a door portion that is openably and closably attached to the case body portion by surrounding and supporting the multi-layer glass in the sash frame material. In general, it is composed of

[0004] In addition, the case body of the cold storage showcase having such a structure is usually provided with an inner frame located on the contact side with the door when closed, and a case body supported by the inner frame. And an outer frame part for makeup that covers the opening side of the part.

FIG. 2 is an enlarged vertical sectional view of an essential part showing an example of a conventional structure of the lower side of the above-mentioned enclosure provided in the case body of the cool-insulated showcase. The inner frame portion 3 located on the contact side is formed with a space therein by mainly using a metal structural material.

That is, the inner frame portion 3 is covered with a top cover 3b and a bottom cover 3c with respect to a partition wall portion 3a which is provided upright in parallel with the vertical opening surface of the case body portion 1.
Further, an inner cover 3d is formed by attaching the inner cover 3d to the upper cover 3b and the bottom cover 3c, and between the inner cover 3d and the partition 3a is used as a cable box for various wirings. A space 4 is provided.

The decorative outer frame portion 5 formed by using an appropriate metal material such as a stainless steel material inserts and fixes a wood screw S from the upper surface cover 3b of the inner frame portion 3 to the support member W side. While being supported by this, it is covered by the opening peripheral portion of the case main body 1.

In addition, the upper end concave curved portion 3a of the partition 3a

0, and the heat insulating resin material 7 and the cushioning heat insulating material 10 cause dew condensation due to a decrease in temperature on the side of the surrounding frame 2, particularly, on the side of the decorative outer frame 5, due to cool air inside the refrigerator. The heat insulation function for suppressing the occurrence is provided.

[0009]

By the way, even with the conventional structure shown in FIG. 2, the heat transmission coefficient of the surrounding frame 2 itself is reduced by the heat insulating resin material 7 and the cushioning heat insulating material 10, thereby lowering the temperature due to cold air in the refrigerator. In order to prevent the occurrence of dew condensation, it is possible to raise the temperature of the surrounding frame portion 2, especially the decorative outer frame portion 5 side, to the dew point temperature of the external atmosphere or more by energizing and heating the cord heater. Can do it.

However, although the surrounding frame portion 2 includes the heat insulating resin material 7 and the cushioning heat insulating material 10 therein,
It cannot be said that it always maintains sufficient heat insulating performance, and therefore, it is not possible to reliably prevent the occurrence of dew condensation due to the influence of cold air in the refrigerator due to outside air that has entered from the joint of each part of the enclosure 2. Moisture generated in the space 4 due to the defrosting operation (usually about 30 minutes) performed after the normal operation for 7 to 10 hours leaks out of the case along a path shown by a broken line, for example, and the showcase It was dangerous, for example, that the floor on which it was placed could get wet, causing shoppers to fall.

Further, in order to sufficiently prevent the generation of such moisture, that is, the occurrence of dew condensation, the cord heater is energized and heated with relatively large electric power so that the temperature of the surrounding frame 2, especially the outer frame 5 for makeup, is reduced to the outside. It must be kept above the dew point temperature of the atmosphere, and the power supply for
20W or more is required, and there is a disadvantage that the power consumption becomes large, and there is a disadvantage that the heat-insulating resin material 7 and the cushioning heat-insulating material 10 must be built in the surrounding frame portion 2. In addition to the need for complicated assembling work, as well as the structural complexity, the number of man-hours required to manufacture this product increases, which delays product delivery and increases production costs, as well as repairs. The maintenance cost for the operation also increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has an inner space portion which has a space therein and which is located on a contact side with a door portion when closed. And a case body provided with a surrounding frame part comprising an outer frame part for makeup that is supported by the inner frame part and covers the opening side of the case body part. At least the lower side of the inner frame part Drainage means for discharging moisture from the space toward the inside of the case body is provided near one end, and water generated in the space in the longitudinal direction is guided to the drainage at the lower side of the inner frame. An object of the present invention is to provide a frame structure in a case main body of a cool-insulated showcase, which has a groove-shaped portion.

[0013]

For this reason, after the outside air entering from the joint of each part of the surrounding frame portion is dewed by the influence of the cool air in the refrigerator, the dew is released by the defrosting operation, and the moisture generated in the space portion is removed by the groove-shaped portion. Water is collected and discharged to the inside of the case main body 12 by drainage means provided near one end of the lower side of the inner frame portion, and moisture does not leak outside the case, that is, in a store with traffic.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an enlarged vertical sectional view of an essential part showing an embodiment of a lower side of an enclosing frame according to the present invention. A case main body 12 of a cool storage showcase 11 such as a frozen showcase or a refrigerated showcase is shown. The surrounding frame portion 13 includes a space portion 15 therein and an inner frame portion 14 located on a contact side with a door portion when closed, and a case body portion 1 supported by the inner frame portion 14.
2 and a cosmetic outer frame 21 covering the opening side.

The inner frame portion 14 is made of a non-metallic material having a low thermal conductivity and a high moldability, such as a synthetic resin material or a rubber material, to prevent a temperature drop due to the influence of cool air inside the refrigerator. It is preferable to form it by using an appropriate metal material if necessary.

Further, a groove 17 is provided in the longitudinal direction on the lower side of the inner frame portion 14 formed by using the above members, and the moisture generated in the space 15 is collected in the groove 17. Water is discharged to the inside of the case body 12 by the drainage means 16 provided near one end of the lower side of the inner frame portion 14.

The drainage means 16 may be appropriately selected from those capable of discharging moisture smoothly, such as a tube or a pipe. The drainage means 16 is further connected to a drain pan inside the case body 12. This is preferable in that water can be efficiently treated without exposing the inside of the case main body 12.

On the other hand, the decorative outer frame portion 21 is preferably formed by using a metal structural material such as an aluminum material, and the projecting portion of the inner frame portion 13 attached to the support member W side. It is supported by fixing a wood screw S to the support member W side via 19.

Since the present invention is constructed in this way, outside air enters the space 15 from the seam between the inner frame 14 of the surrounding frame 13 and the outer frame 21 for makeup, and dew condensation occurs. Thereafter, water generated when the defrosting operation is performed flows into the groove portion, and the water is drained by the drainage means 16 without leaking out of the case.

The showcase may be tilted to the right or left due to the conditions of the installation place or an error in assembling. It is preferable to be provided over the entire longitudinal direction below the portion, and it is preferable that drainage means are provided at both ends of the inner frame portion.

[0022]

As described above, according to the present invention, after the outside air entering from the joint of each part of the surrounding frame condenses due to the cool air in the refrigerator, the moisture generated in the space by the defrosting operation is reduced. The water is collected in the groove portion and discharged to the inside of the case main body by the drainage means provided near one end of the lower side of the inner frame portion, and the water may leak out of the case, especially into a store with traffic. Absent.

Further, according to the present invention, even if moisture is generated in the space of the surrounding frame portion, a sufficient drainage path is secured so that the moisture does not leak out of the case with traffic. It is not necessary to actively prevent condensation in the space, and to sufficiently prevent the occurrence of condensation, the cord heater is energized and heated with relatively large electric power. The temperature does not need to be maintained at or above the dew point temperature of the external atmosphere, and the power consumption can be relatively reduced and the cord heater can be configured without energizing heating or energizing heating at all.

Further, since the built-in heat insulating material of the surrounding frame portion which is required for the conventional product is not required, the entire structure can be simplified, and therefore, the time required for the product can be shortened to shorten the delivery time of the product. In addition to this, it can also contribute to reduction of manufacturing costs and maintenance costs.
