Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device for a refrigerated storage provided with a discharge duct for discharging cold air that has exchanged heat with a cooler into a storage chamber.

[0002]

2. Description of the Related Art Heretofore, a cooling storage of this kind has a storage chamber formed in a main body composed of a heat insulating box, as shown in, for example, Japanese Patent Laid-Open No. 6-129755 (F25D21 / 14). A blower for circulating cold air discharges cool air that has exchanged heat with a cooler through a discharge duct and circulates it to cool it to a predetermined temperature.

Further, since various foods are stored in the storage chamber, the odor generated from them is filled in the storage chamber.
Since these odors are transferred to other foods and spoil the flavor, conventionally, a deodorant such as activated carbon or a deodorizer such as an ozone generator is installed in the storage chamber.

Of these, the deodorizer such as an ozone generator has a complicated structure and is expensive, and since it is necessary to provide electric wiring, the total cost rises. On the other hand, a deodorant using activated carbon or the like is inexpensive and easy to handle such as mounting, but it needs to be replaced when it is saturated and the deodorizing function is impaired. Therefore, in recent years, a deodorizing agent using a catalyst such as manganese for decomposing odorous components together with activated carbon has been developed, and such a deodorizing agent can eliminate the need for replacement or can significantly extend the interval.

[0005]

However, these deodorants adsorb odorous components in the air in contact therewith, that is, the air around it or the air passing through it,
Since it decomposes, the deodorizing efficiency is inevitably lower than that of an electric deodorizer.

Further, if the deodorant is installed in the storage chamber, the volume of the storage chamber is reduced, which hinders the storage of food. Therefore, if the deodorant is placed in the vicinity of the cooler (cooling chamber or the like), which is irrelevant to the effective volume of the storage chamber (the volume that can store food), then replacement of the deodorant becomes extremely difficult.

The present invention has been made in order to solve the above-mentioned conventional technical problems, and it is possible to improve the deodorizing efficiency of a deodorant and to deodorize a cold storage that does not adversely affect the volume of the storage chamber. The purpose is to provide a device.

[0008]

The deodorizing apparatus according to the invention of claim 1 is applied to a cooling storage cabinet provided with a discharge duct for discharging cool air that has exchanged heat with a cooler into a storage chamber. The agent is inserted into the discharge duct, and is arranged in parallel to the cold air flow direction of the discharge duct and with a gap between it and the wall surface forming the discharge duct.

The deodorizing device according to the second aspect of the present invention is applied to a cooling storage cabinet provided with a discharge duct for discharging cool air that has exchanged heat with a cooler into a storage chamber, and is located near the discharge port of the discharge duct. And a deodorant that is detachably supported by the fitting and disposed in the discharge duct. The deodorant can pass through the discharge port of the discharge duct. The fitting has a size and has a holding portion that prevents the deodorant from falling off at a position separated from the discharge port.

[0010]

The dead space of
It becomes possible to effectively utilize the volume of the storage chamber. In addition, the deodorant is located inside the discharge duct, and the wall surface of this discharge duct plays the role of a guard. It becomes possible to avoid damage to the agent.

In particular, since the plate-shaped deodorant is arranged in parallel to the cold air flow direction of the discharge duct and at a distance from the wall surface forming the discharge duct, the deodorant is discharged from the discharge duct. The deodorant in the form of a plate is unlikely to be an obstacle to the cold air flowing through the air, and also serves as a rectifying plate for the cold air, so that the discharge air volume hardly decreases. Further, since the cold air flows around the deodorant, the contact area with the cold air increases, and since the dry cold air passes through the surroundings, the ability of the deodorant to absorb moisture is prevented from deteriorating its performance, and the deodorizing effect is significantly improved as a whole. Can be achieved.

Further, according to the deodorizing device of the cooling storage of the invention of claim 2, since the deodorizing agent is arranged in the discharge duct for discharging the cool air in the storage chamber, the deodorizing agent is conventionally generated by mounting the deodorizing agent. It is possible to eliminate the dead space of the storage chamber that has been used, and to effectively utilize the volume of the storage chamber. Similarly, the deodorant is located inside the discharge duct, and the wall surface of this discharge duct plays a role of a guard. It becomes possible to avoid damage to the deodorant.

In particular, the deodorant has such a size that it can pass through the discharge port of the discharge duct, is detachably supported by a fixture fixed near the discharge port in the discharge duct, and is not attached to the fixture. Since the holding portion for preventing the deodorant from falling off is provided at a position separated from the discharge port, the deodorant can be replaced from the discharge port of the discharge duct. Therefore, it becomes possible to replace the deodorant having a reduced deodorizing ability very easily, and the maintenance workability is remarkably improved.
