Abstract

A vending machine includes a bending machine main body, an internal heat exchanger, an external heat exchanger made of aluminum, a compressor. The vending machine further includes an attachment base made of a steel plate and disposed on the base such that the external heat exchanger and the compressor are provided on the attachment base, and a pair of right and left holding members made of synthetic resin and engaging with and fixing to the attachment base, each having an accommodation unit corresponding to an outer shape at two sides of a lower portion of the aluminum external heat exchanger. The pair of right and left holding members form a gap between the aluminum external heat exchanger and the attachment base such that the two sides of the lower portion of the aluminum external heat exchanger are accommodated and held in the accommodation units.

First claim

What is claimed is:

1 . A vending machine comprising:
a bending machine main body formed as a heat-insulated housing, and having a product accommodation chamber, a machine chamber and a base, an internal heat exchanger installed in the product accommodation chamber, an external heat exchanger made of aluminum and installed in the machine chamber of the vending machine main body, a compressor installed in the machine chamber and forming a refrigeration cycle together with the internal heat exchanger and the external heat exchanger, an attachment base made of a steel plate and disposed on the base, the external heat exchanger and the compressor being provided on the attachment base, and a pair of right and left holding members made of synthetic resin and engaging with and fixing to the attachment base, each having an accommodation unit corresponding to an outer shape at two sides of a lower portion of the aluminum external heat exchanger, wherein the pair of right and left holding members forms a gap between the aluminum external heat exchanger and the attachment base such that the two sides of the lower portion of the aluminum external heat exchanger are accommodated and held in the accommodation units.

2 . The vending machine according to claim 1 , wherein the aluminum external heat exchanger includes a flat tube forming a meandering refrigerant flow path and connected to an inlet header and an outlet header provided at one side in a right/left direction, and a corrugated fin adhered to a horizontally extending portion of the flat tube and having a width protruding in a forward/backward direction from a horizontally extending portion of the flat tube, the flat tube and the outlet header being made of aluminum, and
the accommodation units of the pair of right and left holding members accommodate and carry a flat fin protruding in the forward/backward direction from the horizontally extending portion of the flat tube.

3 . The vending machine according to claim 1 , further comprising a wind tunnel made of a steel plate and covering the aluminum external heat exchanger, the wind tunnel having a shield unit shielding a flow of wind to right and left end portions which are portions of hairpin-shaped bent portions formed following the horizontally extending portion of the flat tube.
