Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of storing dewatered water such as defrosted water of a cooler or water from inside of a refrigerator generated by a defrosting operation or the like in an evaporating dish and evaporating the water in the evaporating dish. Related to commercial refrigerators.

[0002]

2. Description of the Related Art In a commercial refrigerator, waste water from a refrigerator body is stored in an evaporating dish, and the waste water in the evaporating dish is heated by a compressor or a condenser constituting a refrigerator or an electric heater. The water is forcibly evaporated by the heat of the air and exhausted as steam to the outside of the refrigerator.

[0003] In the case of a type of evaporating by the heat of a refrigerator, a compressor and a condenser must be arranged in consideration of the position of an evaporating dish. There is a problem that the degree of freedom is limited. On the other hand, in the case of the type that evaporates by the heat generated by the electric heater, the positions of the evaporating dish, the compressor and the condenser can be freely selected, so that the piping structure and the like are not complicated, and the design There is an advantage that the degree of freedom is increased.

[0004] In the type of evaporating by the heat generated by the electric heater, by disposing the evaporating dish and the electric heater on the bottom surface of the refrigerator main body, the gap between the bottom surface of the refrigerator main body and the floor surface can be effectively utilized.

[0005]

However, the temperature of the waste water immediately after flowing into the evaporating dish does not rise immediately even if it is heated by the electric heater because it is cold. For this reason,
There is a problem in that the evaporating dish is cooled, dew condensation occurs on the outer surface of the evaporating dish, and the dew drops on the floor to wet the floor. In addition, dew condensation easily occurs on the bottom surface of the refrigerator body and the like due to the vapor from the evaporating dish, and in this case, there is a problem that the dew drops on the floor.
Also, it is desirable to quickly evaporate the wastewater in the evaporation dish so that the wastewater does not accumulate in the evaporation dish too much.

Further, it is necessary to take measures to prevent the drainage from overflowing from the evaporating dish and to consider the maintainability of the evaporator.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an evaporator for a commercial refrigerator, which efficiently evaporates waste water from a refrigerator main body and hardly causes dew condensation on an outer surface of an evaporating dish. Another object of the present invention is to make it possible to easily remove and wash the evaporating dish. Another object of the present invention is to prevent the drainage from overflowing from the evaporating dish and to improve the maintainability of the evaporator.

[0008]

In the commercial refrigerator to which the present invention is applied, waste water from the refrigerator body 1 is stored in the evaporating dish 3, and the waste water in the evaporating dish 3 is heated by the heating means H. Evaporated. The heating means H here corresponds to an electric heater or the like. The present invention relates to such a commercial refrigerator, in which a blowing means B for blowing air laterally to the evaporating dish 3 is provided.
Is provided. The blowing means B corresponds to a fan motor or the like, but also includes a wind tunnel section 7 for guiding the blowing of the fan motor to the evaporating dish 3.

More specifically, an evaporating dish mounting shelf 4 having front and rear openings is provided on the lower surface of the refrigerator body 1.
Has a heating means H disposed on the bottom surface 4a on which the evaporating dish 3 is placed. Then, the mounting plate 11 provided with the blowing means B
Can be swingably attached to one opening side of the evaporating dish mounting shelf 4 so that one opening of the evaporating dish mounting shelf 4 can be opened and closed by the mounting plate 11.

A means 3b is provided for discharging the overflow of the evaporating dish 3 to the outside of the refrigerator. Further, the blowing means B is arranged in front of the evaporation dish 3.

[0011]

According to the commercial refrigerator of the present invention, the waste water from the refrigerator main body accumulates in the evaporating dish 3 and is heated by the heating means H to evaporate. Then, while the dry outside air is blown laterally to the evaporating plate 3 by the blowing means B, the air containing the vapor on the upper side of the evaporating plate 3 is quickly exhausted to the outside of the refrigerator. You.

Therefore, the efficiency of evaporating the waste water in the evaporating dish 3 increases. In addition, since the periphery of the outer surface of the evaporating dish 3 is in a dry state, dew condensation hardly occurs on the outer surface of the evaporating dish 3 and the like, and it is possible to prevent the dew from dripping on the floor and wet the floor. In addition, since the air is blown laterally to the evaporating plate 3, the air flows along the water surface of the drainage in the evaporating plate 3 and the side surfaces of the evaporating plate 3, so that the air is efficiently disturbed without much disturbance. Flows. As a result, the blowing efficiency is improved, which further contributes to an increase in the evaporation efficiency and a suppression of the dew condensation.

When the evaporating dish mounting shelf 4 is provided on the lower surface of the refrigerator main body 1 and one opening of the evaporating dish mounting shelf 4 is opened and closed by a mounting plate 11 provided with a blowing means B, the refrigerator The space between the bottom surface of the main body 1 and the floor surface can be effectively used, and the mounting plate 11 is swung to a position where it does not hinder the removal of the evaporating dish 3, so that the evaporating dish 3 is placed on the evaporating dish. It can be easily taken out from one opening of the shelf 4 and washed.

If the means 3b for discharging the overflow of the evaporating dish 3 to the outside of the refrigerator is provided, even if a large amount of wastewater flows into the evaporating dish 3 in a short time when washing the inside of the refrigerator, the evaporating dish 3
It is possible to reliably prevent the drainage from overflowing from the floor and to wet the floor.

If the blower means B is arranged in front of the evaporating dish 3, the maintenance of the blower means B can be easily performed from the front side of the refrigerator even if the rear side of the refrigerator is arranged close to a wall or the like. Can be done.
