Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ethylene removing and deodorizing device for removing ethylene gas and malodor in the air in a refrigerator such as a prefabricated refrigerator or a showcase for flowers.

[0002]

2. Description of the Related Art Conventionally, in a prefabricated refrigerator of this type, for example, JP-A-4-184071 (F25D2) is used.
As shown in 3/06), an inner box of good heat conductivity is provided in an outer box composed of a heat insulating box at intervals, and cold air is circulated as a duct between these boxes to circulate the inner box. In addition to indirectly cooling the inside of the refrigerator, fresh flowers and wine are stored in the refrigerator so that they can be stored without being dried.

In addition, since ethylene gas generated from the above-mentioned stored articles is filled in the storage and accelerates the aging of the articles, in the above publication, a porous material made of green tuff is attached to adsorb this ethylene gas. I was trying to remove it. However, since such a porous material is heavy and difficult to handle, in recent years, as shown in Japanese Patent Application No. 5-347971 filed by the applicant earlier, an ethylene decomposition catalyst such as palladium was kneaded into activated carbon. The mixed decomposition sheet material was used and stored in the box body attached to the back side of the panel forming the side wall of the inner box.

In this case, the inside of the box communicates with the inside of the box through the ventilation holes formed in the panel, and the air inside the box enters into the box through one ventilation hole, passes through the sheet material, and then the other ventilation hole. More spilled into the warehouse. Such a sheet material has a large ethylene gas removing ability as compared with the above green tuff, has a deodorizing effect, is light in weight and rich in flexibility, and therefore is easy to handle. Further, since it does not adsorb ethylene gas like green tuff, but decomposes, it has various advantages such as a long life.

[0005]

However, in such a conventional panel, when it is attached to the inner surface of the outer box of an existing forced draft type prefabricated refrigerator that does not require indirect cooling, only the panel is inside the side wall of the outer box. Since the side surface of the box body is exposed, it is not desirable for appearance, the mounting position is limited, and the flow rate of cold air in the box body is limited, so ethylene gas can be efficiently used. There was also a problem that could not be processed.

The present invention has been made to solve the above-mentioned conventional technical problems, and is capable of efficiently removing ethylene gas and malodor, and can be easily applied to existing prefabricated refrigerators and the like, and The purpose of the present invention is to provide an ethylene removal deodorizing device that is easy to install.

The circuits are connected in series. The timer 61 is to open the contact after closing the contact inside the heating switch 31 for an arbitrary time that can be changed, and here, for example, it is assumed that 24 hours are set. Further, the bimetal thermo 52 opens the contact at + 60 ° C.
It shall return at 0 ° C.

As shown in FIG. 6, the ethylene removing and deodorizing apparatus 1 is placed on the upper surface of the shelf S with the holding plates 57 and 58 facing downward. When the outlet 56 is connected to a commercial 100V power source (not shown) (the heating switch 31 is not closed here), the power lamp 32 and the blower 27 are energized, the power lamp 32 lights up, and the blower 27 is turned on.
Are operated continuously.

By operating the blower 27, the cold air in the refrigerator 11 is sucked into the air flow path 38 from the air suction port 26 of the box body 20 of the ethylene removing and deodorizing apparatus 1 as shown by an arrow in FIG. After passing through the ventilation hole 40 and the inside while contacting the surface of the agent 41, ..., It is blown into the inside 11 from the air outlet 36. This air suction port 2
The cold air sucked from No. 6 contains ethylene gas and malodorous components generated from the above-mentioned article.
In the process of passing through .., first, it is adsorbed on activated carbon, and ethylene gas is decomposed and removed by palladium and malodorous component by manganese. Therefore, fresh cold air is constantly blown out from the air outlet 36.

Particularly, the ethylene removing deodorant sheet agent 41 ...
Is provided at a substantially right angle to the flow direction of the cool air flowing from the air suction port 26 to the air outlet port 36, and a large number of vent holes 40 are formed, so that the contact area is reduced while reducing the flow resistance of the cool air. Therefore, the ethylene gas and the malodorous components in the interior 11 can be removed smoothly and efficiently as a whole.

Further, ethylene removing deodorant sheet agent 41 ...
Is detachably provided in the box body 20, and the inside of the box body 20 can be opened and closed by the detachable side wall 37 of the exterior decorative plate 21, so that the side wall 37 is removed to remove the ethylene deodorizing sheet agent 41. By pulling out the arrow toward the front side of FIG. 4, it becomes possible to smoothly replace the ethylene removing deodorant sheet material 41.

When the activated carbon etc. in the ethylene removing and deodorizing sheet material 41 is to be regenerated, the ethylene removing and deodorizing apparatus 1 is taken out of the storage (it may be performed in the storage 11) and the outlet 56 is used as a power source. Connect and close the heating switch 31. Then, the contact of the timer 61 is initially closed,
Since the contact of the bimetal thermo 52 is also closed, the heating lamp 33 is turned on and the heater 51 generates heat. still,
Due to the heat generated by the heater 51, the temperature inside the box body 20 rises abnormally, and when the temperature rises above + 60 ° C., the bimetal thermostat 52 opens the contact, so that the occurrence of an accident due to overheating is eliminated.

Since the activated carbon and the like in the ethylene removing and deodorizing sheet material 41 is regenerated by the heat generated by the heating heater 51, it is possible to always exert stable decomposition processing ability of ethylene gas and malodorous components. Further, even if the heating switch 31 is forgotten to be opened, the contact of the timer 61 is opened after 24 hours, so that the heater 51 is no longer energized. Therefore, it becomes possible to avoid the occurrence of an accident due to forgetting to turn off the heater 51.

Next, FIGS. 8 to 13 show another installation state of the ethylene removing and deodorizing apparatus 1 of the present invention. In each drawing, the same reference numerals as those in FIGS. 1 to 7 are the same.
In this case, a pair of slide rails 71, 71 as shown in FIGS. 12 and 13 is attached to the lower surface on the left side of the ceiling panel 4 of the prefabricated refrigerator 2. The slide rails 71, 71 are provided with an outer fixed side 72 and an inner holding side 7 that descends downward from the fixed side 72 in a stepwise manner.
3, and the holding side 73 has an area dimension capable of holding at least the holding plates 57 and 58. Also,
The front and rear edges of the holding side 73 have flanges 7 bent upward.
4, 74 are formed.

The slide rails 71, 71 are spaced apart from each other by a distance slightly larger than the width of the ethylene removing and deodorizing device 1, and the holding sides 73 face each other.
It is screwed to the ceiling panel 4 by 2. In this state, a gap larger than the thickness of the holding plates 57 and 58 is formed between the flange 74 and the ceiling panel 4 as shown in FIG. Then, using this space, the ethylene removing and deodorizing apparatus 1 is slid as shown by the arrow in FIG. 13 to hold the holding plates 57 and 58 of the ethylene removing and deodorizing apparatus 1 on the holding sides 73 and 73 as shown in FIG. It is attached to the lower surface of the panel 4.

Since the operation of the ethylene removing and deodorizing device 1 is the same as that described above, its explanation is omitted. Further, in the embodiment, the present invention is applied to a prefabricated refrigerator in which the cool air from the cooler is forcibly circulated directly into the refrigerator, but the present invention is not limited to this, and is also effective for showcases for flowers, and so-called indirect cooling type. It goes without saying that the present invention is also effective for the cold storage and the like.
