Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Industrial Application Field) This invention relates to a showcase whose main body is separated into a storage chamber (cooling chamber) and a machine chamber.

(Prior Art) Generally, the main body of a showcase is separated into a storage room and a machine room by a partition. An evaporator is installed in the storage room, and a condenser, compressor, etc. are installed in the machine room. These are connected by piping to form a refrigeration cycle.

By the way, in a showcase structured like this,
The cold air cooled by the evaporator in the storage room has low humidity. Therefore, when the cold air cooled by the evaporator circulates through the storage room, the items displayed in the storage room are not only cooled, but also have moisture removed, leading to a decrease in quality.

Conventionally, in order to eliminate the above problem, a humidifier has been incorporated into the showcase.

However, incorporating a humidifier into the showcase not only complicates the overall configuration, but also increases energy consumption as power must be supplied to the heater etc. to operate the humidifier. This resulted in higher running costs.

(Problem to be solved by the invention) As described above, conventional showcases use a humidifier to humidify the storage room, which leads to complications such as a complicated configuration and an increase in running costs. there were.

This invention was made based on the above-mentioned circumstances, and its purpose is to provide a showcase that can humidify a storage room without using a humidifier.

[Structure of the Invention] (Means and Effects for Solving the Problems) In order to solve the above problems, the present invention provides a showcase equipped with a cooling chamber in which an evaporator is provided inside the main body. A water absorbing member made of a porous molded body that absorbs defrosting water is provided in the part.

Thereby, the defrosting water absorbed by the water absorbing member is dispersed by the air flow circulating in the storage chamber, thereby humidifying the storage chamber.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. The showcase 1 shown in FIG. 3 includes a main body 2. The showcase 1 shown in FIG. The main body 2 has a prismatic shape, and is divided into a storage chamber 3, which is a cooling chamber, on the upper side and a machine room 4 on the lower side. The storage room 3 is covered on all four sides with transparent glass, and one side has a door 5 that can be opened and closed, and this door 5 can be opened and closed to display items that require refrigeration inside. It has become.

The storage room 3 and the machine room 4 are separated by a partition 6 made of a heat insulating material, as shown in FIGS. 1 and 2. This partition body 6 has an open top and a bottom with an upper section 6a.
The evaporator 7 is formed into a step-like box shape with a lower part 6b and an evaporator 7 in the upper part 6a.
A first fan 8 is disposed opposite to the fan 8 . The upper surface opening of this partition 6 is closed by the bottom plate 9 of the storage chamber 3 which is slightly smaller than this opening area, thereby creating a gap between the inner peripheral surface of the opening of the partition 6 and the peripheral part of the bottom plate 9. A ventilation passage 10 is formed therein. Therefore, when the first fan 8 is operated, the cold air in the storage chamber 3 is circulated through the evaporator 7 while exchanging heat, as shown by the arrow in FIG.

A compressor 12 , a condenser 13 , and a second fan 14 facing the condenser 13 are disposed in the machine room 4 formed on the lower surface side of the partition 6 . When the second fan 14 operates, forced ventilation is generated in the machine room 4 in the direction shown by the arrow, thereby cooling the condenser 13. Further, the evaporator 7, compressor 12, and condenser 13 are connected by piping, thereby forming a refrigeration cycle.

A water absorbing member 15 is provided on the inner bottom surface of the partition body 6 over the entire inner bottom surface. That is, the water absorbing member 15 is provided at the bottom of the partition 6, which is a portion through which defrosting water generated by melting frost adhering to a low-temperature location in the storage chamber 3, such as the evaporator 7, flows. This water absorbing member 15 is formed of a porous molded body. The porous molded body is made by sintering a heat-reactive phenolic high-performance thermosetting resin (for example, Unipex manufactured by Unitika Co., Ltd.) with a particle size of 5 to 800μ at 50 to 160°C, and has a large number of pores ( It is a hydrophilic sintered body with a porosity of approximately 35%.

The shape of this sintered compact is usually formed into a flat plate, which is then cut and bent into a desired shape.

In addition, this sintered compact has high hydrophilicity, and when the bottom of the compact is immersed in the water surface, the height of water sucked up for 10 seconds is 20.
It has a high water absorption effect of ~30m+s.

Furthermore, since the sintered molded body is made of resin, it is possible to mix an anti-mold agent, thereby preventing the growth of mold and maintaining a clean state at all times.

Therefore, the defrosting water generated in the storage chamber 3 is absorbed by the water absorbing member 15 provided in the flow path, and is evaporated by the airflow inside the storage chamber 3 generated by the first fan 8. It has become.

Incidentally, a drain port 1 is provided in the lower part 6b of the partition body 6. The water absorbing member 15 corresponding to this drain port 11
A through hole 16 is bored at the location. Therefore, if there is too much defrosting water generated in the storage room 3, it will drip into a drain pan (not shown) through the through hole 16 and the drain port 11.

According to the showcase 1 having such a configuration, when the frost adhering to the evaporator 7 and the like melts to become defrosting water, the defrosting water flows from the upper section 6a of the partition body 6 to the lower section 6b. Since a water absorbing member 15 is provided at the inner bottom of the partition 6 so as to cover the upper section 6a and the lower section 6b, the water absorbing member 15 absorbs defrosting water.

On the other hand, the cold air in the storage chamber 3 is circulated by a first fan 8 provided in the partition 6 as shown by arrows in FIG. Since the water absorbing member 15 is disposed in the flow path of the cold air generated by the first fan 8, the defrosting water absorbed by the water absorbing member 15 is evaporated by the cold air flow generated by the first fan 8. , the storage chamber 3 will be humidified. In other words, storage room 3 without using a humidifier
Can be humidified with defrost water.

Further, if an anti-mold agent is mixed into the water-absorbing member 15, it is possible to prevent mold from forming on the water-absorbing member 15, so that a clean state can be maintained at all times.

FIG. 4 shows another embodiment of the invention. This embodiment is applied to a showcase IA of a different type from the above embodiment. In other words, the front of the storage room 3 is the glass plate 21.
A door 22 is provided on the back surface of the container, and the door 22 can be opened and closed to allow articles to be taken in and taken out. In addition, 23 in the figure is a shelf for placing articles.

An evaporator 7 is arranged in a lower part 6b of a partition 6 that separates the storage room 3 and the machine room 4.

Note that other structures are the same as those in the above embodiment, so the same symbols are given and explanations are omitted.

Also in the showcase IA having such a configuration, the defrosting water generated in the storage chamber 3 is absorbed by the water absorbing member 15 and evaporated by the cold air circulated by the first fan 8. Can be humidified.

In this embodiment, since the evaporator 8, which generates the most defrosting water, is provided in the lower part 6b of the partition 6, the water absorbing member 15 is also provided only in the lower part 6b of the partition 6. Good too.

Further, in each of the above embodiments, the drain port 11 is provided in the partition body 6 and the through hole 16 is provided in the water absorbing member 15 so that defrosting water can be drained when a large amount of water is generated. In this case, the drain port 11 and the through hole 16 do not need to be provided. If the drain port 11 and the through hole 16 are not drilled,
Since it becomes difficult for the cold air in the storage room 3 to escape, operational efficiency can be improved.

[Effects of the Invention] As described above, in this invention, a porous molded body that absorbs defrosting water is provided at the bottom of the cooling chamber, so that the defrosting water absorbed by the porous molded body is absorbed by the porous molded body. The cold air circulating in the cooling chamber is evaporated and humidifies the cooling chamber. Therefore, it is possible to humidify the cooling chamber without having to take the trouble to provide a humidifier as in the conventional case, which has the advantage of simplifying the configuration and reducing running costs.
