Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a refrigerator-incorporated showcase having a contrived arrangement of a drain water evaporator and an improved structure.
[0002]
[Prior art]
Conventionally, Japanese Laid-Open Patent Publication Nos. 7-133777 and 9-89448 have been disclosed as drain water evaporators for refrigerator-incorporated showcases in which the heat exchange of the condenser is air-cooled.
Both publications have a structure in which drain water is directly applied to the evaporation member of the evaporator 31 of the showcase 30 from above. However, since this drain water is low temperature and takes time to evaporate, FIG. As shown, the drain water evaporation device 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. In addition, 34 is a compressor, 35 is a refrigerator (condensing unit), 36 is an evaporation member, 37 is a drain hole, 38 is a drain hose, 39 is a power transmission box, and 40 is a case control box.
[0003]
[Problems to be solved by the invention]
However, because the showcases with built-in refrigerators currently used in the market place the ventilator of the condenser blower on the high-temperature compressor body, a drain water evaporator is placed behind the compressor. Therefore, the ventilation hits the compressor and is scattered to the left and right, so that it is impossible to directly apply the ventilation to the evaporation member of the drain water evaporator, and therefore the evaporation effect cannot be expected so much.
Moreover, since the low temperature (0-5 degreeC) drain water is hung directly on the evaporation member, it is hard to evaporate.
Furthermore, if the drain water evaporator is disposed behind the compressor, the depth of the showcase becomes large, and the conventional drain water evaporator cannot be used for a showcase with a small depth.
From such a background, in Japanese Patent Application Laid-Open No. 9-89448, a multistage case with a large amount of drain water is provided with a drain water raising device and an alarm device, but the structure becomes complicated and causes cost increase. It has become.
[0004]
The present invention was devised in view of the above-described problems, and can be expected to have an evaporation effect, can be applied to a showcase with a small depth, can be reduced in cost, and the heat exchange of the condenser is a water-cooled showcase Another object of the present invention is to provide a refrigerator-incorporated showcase equipped with a drain water evaporation device that can be applied to the above.
[0005]
[Means for Solving the Problems]
In order to solve the above-described problems, in the present invention, a compressor, a condenser, and a condenser blower that are constituent elements of the refrigerator are a showcase that cools products displayed in the case by a built-in refrigerator. And a drain water evaporator that collects drain water and evaporates the drain water is isolated from the flow path of the condenser blower in the refrigerator built-in showcase installed inside the lower frame of the case. A drain water evaporator is provided beside the refrigerator, the drain water evaporator is a tray that receives drain water, an evaporation member that is provided in the tray and absorbs and evaporates the drain water, It is characterized by comprising a dedicated blower arranged downward so as to blow on the bottom surface of the tray.
[0006]
And it is desirable that this drain water evaporation apparatus is made into a kit by itself.
[0007]
By adopting such a configuration, the drain water evaporator can be installed in the space next to the refrigerator even in a showcase with a small depth. Moreover, the evaporation effect of drain water can also be improved by attaching a dedicated air blower to the drain water evaporator.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described 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 the same showcase base, and FIG. 3 is a sectional side view of the main part of the showcase. 4 is an exploded perspective view of the drain water evaporator, FIG. 5 is an exploded perspective view of the evaporation member and the fixing member, FIG. 6 is a plan view, and FIG. 7 is a side view.
[0009]
First, as shown in FIGS. 1 to 3, this type of flat showcase 1 includes a product display portion 2 formed in a box shape with an open top, and a pedestal that keeps the product display portion 2 at an appropriate height. The refrigerator 3 (condensing unit) 4 is built in the gantry 3. That is, the condenser 5 which is a component of the refrigerator 4 is provided in the front, a condenser blower 6 for attracting air is disposed behind the condenser 5, and a compressor 7 is disposed further rearward. In addition, 8 is an electrical equipment box. And the airflow in this refrigerator 4 becomes a structure of front suction and back blowing.
[0010]
By the way, although the conventional drain water evaporation apparatus was provided in the flow path behind the compressor 7 using this air flow, this invention isolate | separates from the flow path of this fan 6 for condensers, and it is a refrigerator. Next to 4, a drain water evaporator 9 is provided. And as shown in FIG. 3, the drain hole 10 is pierced in the lower end of the goods display part 2, and it is comprised so that drain water may be dropped to the saucer 12 of the drain water evaporator 9 with the drain hose 11. FIG. Reference numeral 13 denotes a case control box.
[0011]
Next, the drain water evaporator 9 which is the gist of the present invention will be described with reference to FIGS.
The drain water evaporation device 9 includes a drain tray 12 that receives drain water falling from the drain hose 11, a plurality of evaporation members 16 that absorb and evaporate drain water accumulated in the drain tray 12 by capillary action, It is generally constituted by a dedicated blower 17 disposed downward so as to blow on the bottom surface of the drain tray 12.
[0012]
The drain tray 12 is placed on a reverse convex tray slide rail 18 whose lower side is open so as to be movable in the front-rear direction. A U-shaped fan motor mounting bracket 19 is provided behind the tray slide rail 18, and a dedicated blower 17 is mounted thereon. A stopper 20 is provided at the foremost part of the tray slide rail 18, and a blind plate is provided at the rear part.
A substantially U-shaped evaporating member fixing bracket 21 is welded to substantially the center of one side of the drain tray 12, and the evaporating member 16 is attached to the opening. Each plate of the evaporation member 16 has notches 16a and 16a in the longitudinal direction on both sides thereof, and the comb-like notches 22a, 22a... Of the fixing members 22 and 22 are fitted into the notches 16a. (See FIG. 5).
[0013]
The material of the evaporating member 16 is a non-woven fabric such as polyester fiber, and the base material is thermally cured with fine phenol, and is further soaked in an alcohol-based solvent to impart hydrophilicity. It is good to use what was dried.
The drain water evaporator 9 can be applied regardless of the type and size of the showcase, and is a single kit.
[0014]
If comprised in this way, also in the showcase with a small depth, while being able to install a drain water evaporation apparatus beside a refrigerator, since the exclusive air blower was employ | adopted, the evaporation effect of drain water improves.
[0015]
【The invention's effect】
As described above, according to the showcase with a built-in refrigerator according to the present invention, the following effects can be obtained.
(1) By blowing out a dedicated blower toward the bottom surface of the drain tray, the temperature of the drain water rises, and when it is absorbed by the evaporation member, it is in a state of being easily evaporated. Further, since the wind blown on the bottom surface directly hits the evaporation member, the evaporation effect of the evaporation member is further improved.
(2) Since it is installed beside the refrigerator, it can be used for a showcase with a small depth.
(3) In addition to the showcase in which the heat exchange of the condenser is performed by air cooling, it can be used for a showcase performed by water cooling.
(4) Since the evaporation effect is enhanced by the dedicated blower, the conventional elevating member raising device and alarm device as disclosed in Japanese Patent Laid-Open No. 9-89448 are not required, and the cost can be reduced. And especially this invention can be used also for the multistage showcase with much drain drainage.
