Abstract

Abstract The cold side of the module(s) (1) is coupled to a dissipator element (2) facing directly onto the refrigerator compartment (9). The hot side faces onto a ventilated dissipator element (3) that dispels the calories generated by the reverse thermoelectric process. Appropriate thermic insulation (12) between the hot side and the cold side optimizes the use of the refrigeration units produced. The thermoelectric module (1) is powered by direct low-voltage current flowing in one direction only and such as to generate on the cold side the amount of refrigeration units necessary to suitably cool a refrigeration compartment which is capable of performing its traditional function without limits. The refrigerator according to the invention can be subordinated, by means of an electronic circuit (6), to the signal transmitted by a temperature sensor located inside the refrigerator compartment which enables the user to set up a temperature-control program, and to select precisely defined operating conditions.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 95 words
A refrigerator incorporating thermoelectric modules with reverse thermoelectric effect, essentially comprising the following elements: - a container with a high level of thermic insulation; - access means from the outside to the inner area of the container; - Peltier-effect generating modules; - means for supplying the generating modules with direct current; - means for distributing the refrigeration units generated within the container; - means for dispersing the calories externally; - thermic insulation means between the aforesaid means for distribution and dispersion; - cooling means; and - optionally, electronic means for piloting the Peltier-effect generating modules.
Claim 2
Dependent Claim 95 words
A refrigerator incorporating thermoelectric modules with reverse thermoelectric effect, essentially comprising the following elements: - a container with a high level of thermic insulation; - access means from the outside to the inner area of the container; - Peltier-effect generating modules; - means for supplying the generating modules with direct current; - means for distributing the refrigeration units generated within the container; - means for dispersing the calories externally; - thermic insulation means between the aforesaid means for distribution and dispersion; - cooling means; and - optionally, electronic means for piloting the Peltier-effect generating modules.
