JP-A-7-133977 and JP-A-9-8944
No. 8 is disclosed. Each of the publications has a structure in which drain water is directly applied to the evaporating member of the evaporator 31 of the showcase 30 from above. However, since this drain water has a low temperature and takes a long time to evaporate, FIG. As shown in (2), a drain water evaporator 31 is provided in the flow path of the blower 33 for the condenser 32, and the ventilation effect of the blower 33 is applied to improve the evaporation effect. 34 is a compressor, 35 is a refrigerator (condensing unit), 36 is an evaporating member, 3
7 is a drain hole, 38 is a drain hose, 39 is an electric transmission box, and 40 is a case control box.

However, in the case of a refrigerator-incorporated showcase currently used in the market, the ventilation of the condenser blower is applied to the compressor body, which is heated to a high temperature. The device must be located behind the compressor, and the ventilation hits the compressor and scatters to the left and right, and it is impossible to directly apply the ventilation to the evaporating member of the drain water evaporator, and therefore the evaporation effect is not so large. Can't expect. Further, since the low-temperature (0 to 5 ° C.) drain water is dripped directly from above the evaporating member, it is difficult to evaporate. Furthermore,
If the drain water evaporator is arranged behind the compressor, the depth of the showcase becomes large, and there is a problem that the conventional drain water evaporator cannot be used in a showcase having a small depth. Against this background, Japanese Patent Application Laid-Open
In JP-89-448A, a drain water rising device and an alarm device are provided in a multi-stage case or the like having a large amount of drain water, but the structure becomes complicated and causes an increase in cost.

The present invention has been made in view of the above-mentioned problems, and can be expected to have an evaporating effect, can be applied to a showcase having a small depth, can achieve cost reduction, and has a water-cooled condenser for heat exchange. An object of the present invention is to provide a refrigerator-integrated showcase provided with a drain water evaporator that can be applied to a certain showcase.

[0005]

According to the present invention, there is provided a showcase for cooling a product displayed in a case by a built-in refrigerator, which is a component of the refrigerator. A compressor, a condenser, a blower for the condenser, etc., and a drain water evaporator for collecting the drain water and evaporating the drain water, etc., are condensed in a refrigerator built-in type showcase installed inside the lower frame of the case. A drain water evaporator is provided on the side of the refrigerator, separated from the flow path of the dexterous blower.

The drain water evaporator includes a receiving tray for receiving drain water, an evaporating member provided on the receiving tray for absorbing and evaporating drain water, and a dedicated blower disposed downward so as to blow the bottom of the receiving tray. It is composed of Further, it is desirable that this drain water evaporator is made into a kit as a single unit.

By employing such a configuration, the drain water evaporator can be installed in the space beside the refrigerator even in a showcase having a small depth. In addition, by attaching a dedicated blower to the drain water evaporator, the drain water evaporation effect can be improved.

[0008]

Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a refrigerator-incorporated showcase to which the present invention is applied, FIG. 2 is a plan view of the inside of a stand of the showcase, and FIG. 3 is a cross-sectional side view of a main part of the showcase. 4 is an exploded perspective view of a drain water evaporator, FIG. 5 is an exploded perspective view of an evaporating member and a fixing member, FIG. 6 is a plan view, and FIG. 7 is a side view.

First, as shown in FIGS. 1 to 3, a flat-type showcase 1 of this type has a commodity display section 2 formed in a box shape with an open top, and the commodity display section 2 has an appropriate height. And a chiller (condensing unit) 4 is built in the gantry 3. That is, a condenser 5 which is a component of the refrigerator 4 is provided on the front side, a blower 6 for a condenser for inducing air is arranged behind the condenser 5, and a compressor 7 is arranged further behind the condenser. Reference numeral 8 denotes an electrical box. The air flow in the refrigerator 4 has a configuration of suctioning from the front and blowing out from the back.

By the way, the conventional drain water evaporator is provided in the flow path behind the compressor 7 by utilizing this air flow. However, the present invention is separated from the flow path of the blower 6 for the condenser. A drain water evaporator 9 is provided beside the refrigerator 4. Then, as shown in FIG. 3, a drain hole 10 is formed in the lower end of the product display unit 2, and the drain hose 11 allows the drain water to drop onto the tray 12 of the drain water evaporator 9. Reference numeral 13 is a case control box.

Next, a drain water evaporator 9 according to the gist of the present invention will be described with reference to FIGS. The drain water evaporator 9 includes a drain tray 12 for receiving drain water falling from the drain hose 11, a plurality of evaporating members 16 for absorbing and evaporating the drain water accumulated in the drain tray 12 by capillary action, It is generally constituted by a dedicated blower 17 arranged downward so as to blow on the bottom surface of the drain pan 12.

The drain tray 12 is mounted on an inverted convex tray slide rail 18 having an open lower side so as to be movable in the front-rear direction. Behind the tray slide rail 18, a U-shaped fan motor mounting bracket 19 is provided, on which a dedicated blower 17 is mounted.
A stopper 20 is provided at the forefront of the tray slide rail 18,
Blind boards are provided at the rear end, respectively. At the approximate center of one side of the drain pan 12, a U-shaped evaporating member fixing bracket 21 is welded, and the evaporating member 16 is attached to this opening. Each plate of the evaporating member 16 has notches 16a, 16a in the longitudinal direction on both sides thereof, and the comb-shaped notches 22a, 22a... Of the fixing members 22, 22 are fitted into the notches 16a. (See FIG. 5).

The material of the evaporating member 16 is a non-woven fabric such as a polyester fiber as a base material, and a fine particle phenol is thermally cured on the base material to form a fixing agent. After drying, it is preferable to use a dried product. The drain water evaporator 9 can be applied irrespective of the type and size of the showcase, and is made as a single unit.

With this configuration, even in a showcase having a small depth, the drain water evaporator can be installed beside the refrigerator and a dedicated blower is used, so that the drain water evaporating effect is improved.

[0015]

As described above, according to the showcase with a built-in refrigerator of the present invention, the following effects can be obtained. (1) By blowing out a dedicated blower toward the bottom of the drain pan, the temperature of the drain water rises, and the water is easily evaporated when absorbed by the evaporating member. Further, since the wind blown to the bottom directly hits the evaporating member, the evaporating effect of the evaporating member is further improved. (2) Since it is installed beside the refrigerator, it can be used for showcases with a small depth. (3) In addition to a showcase in which heat exchange of the condenser is performed by air cooling, the present invention can be used in a showcase in which water is cooled. (4) Since the evaporative effect was enhanced by a special blower,
A conventional elevating member elevating device and an alarming device as disclosed in Japanese Patent Application Laid-Open No. 9-89448 are not required, and the cost can be reduced. In particular, the present invention can be used for a multi-stage showcase having a large drainage amount.
