Abstract: A refrigeration apparatus comprises a machine chamber for containing a compressor, a condenser and others, and a display chamber for accommodating articles to be displayed. The display chamber is constituted by an inner box and an outer box between which a cooling air passage is defined. Defined internally of the machine chamber is a cooler chamber enclosed substantially by a heat insulating material in such a manner as to communicate with the cooling air passage. Disposed within the cooler chamber is a cooling air circulating device and a cooler for causing the cooling air to circulate through the cooling air passage and back to the cooler chamber.

Abstract: A dishwasher comprises a main body having a washing tub. A box-like cover is mounted above the washing tub to be movable between a lower position to close the washing tub and an upper position to expose the tub. A supporting frame having a channel-like cross section for supporting the cover and guiding the movement thereof is mounted so as to extend from the washing tub into the interior of the cover. A pair of coil springs are provided to the inside of the channel-like supporting frame and have respective lower ends secured on the supporting frame at the inner side thereof and respective upper ends secured to a shield member which assumes a blocking position to substantially close an opening formed in a top wall of the cover when the latter is at the upper position while assuming a releasing position where the top opening of the cover is released from the blocked state. The shield member is swingable between the blocking position and the releasing position.
