Abstract
A defrosting apparatus comprises a housing defining therein a frozen food storage space. Within the housing, air is heated and supplied to the storage space through a hot-air entrance passage formed between a side wall of the housing and one of paired shelf receiving members which cooperate to define the storage space. The hot-air entrance passage incorporates a guide plate having a communication aperture provided at a lower end. The guide plate cooperates with the side wall of the housing and one of the shelf receiving members to force the hot air fed from a ventilating fan to flow first downwardly along the hot-air inlet passage. The hot-air flow is then changed in the flow direction upon passing through the communication aperture so as to flow upwardly. In the course of flowing upwardly, the hot air is fed into the storage space successively through a plurality of inlet ports formed in one of the shelf receiving members.
