Further, the humidifying container is provided with a drainage hole for discharging water, the back wall of the humidifying container is exposed from the refrigerator main body to be brought close to the heat generating part, and the humidifying container is provided with a humidifying hole that communicates with the interior of the refrigerator.

(E) Function According to the present invention, the defrosting water from the cooler is introduced into the humidifying container, where the necessary amount is absorbed by the porous water absorbing body, and the surplus is discharged from the drain hole. Become. The moisture contained in the porous water absorbent body is heated from the back side of the humidifying container by the heat generating part of the cooling device, and is efficiently evaporated and dissipated into the refrigerator, so that the interior of the refrigerator is quickly humidified.

In addition, the porous water absorbent body is stored in the humidifying container and is not exposed outside the refrigerator body, suppressing the dissipation of moisture, so that the humidifying function of the porous water absorbent body continues stably. Furthermore, by suppressing complete drying of the porous water absorbent body, ventilation of the porous water absorbent body is suppressed, and therefore, entry of outside air from the porous water absorbent body is prevented.

It is stored in a non-vibration absorption refrigerator to prevent stirring of the sediment and is a public product.

As shown in FIGS. 2 and 3, the humidifying device (16) stores a porous water absorbent (19) having a laminated structure in a humidifying container (20). (20) is installed through the heat insulating wall (3). The porous water absorber (19) is
It is made of an alumina-based material that was developed with particular emphasis on its water absorption properties due to capillarity, and its characteristics include the gasification of organic matter in the raw materials during the firing process, and the volume reduction caused by oxidation and melting of metal compounds, which releases water to the outside. It is formed by continuous pores of a certain size. Furthermore, when the moisture contained in the porous water absorbent body (]9) completely evaporates, it becomes breathable because of its continuous pores. Further, the humidifying container (20) has the cooling! An introduction hole (21) for introducing the defrosting water (12) is provided to introduce the drain pipe (15), and a drain hole (21) for discharging excess defrosting water is provided at the bottom of the humidifying container (20). 22) is provided.
