Refrigerator-oven complex
First Claim
1. A refrigerator-oven complex comprising a refrigerator space and an oven space thermally insulated from one another, and a refrigerating-heating system for cooling said refrigerator space and for heating said oven space, said system containing a refrigerant and comprising a cooling coil in said refrigerator space, a heating coil in said oven space, a motor-driven compressor for compressing refrigerant vapor received from said cooling coil, a condensor for compressed refrigerant vapor, a trident valve having an inlet connected with the output of said compressor, one outlet connected with an inlet of said heating coil and another outlet connected by a bridge pipe to an inlet of said condenser, an outlet of said heating coil being connected with an inlet of said condenser, refrigerant storage means having an inlet connected with an outlet of said condenser and an outlet connected through a controllable capillary valve with said cooling coil whereby said cooling coil with said capillary valve comprises a volitilator, means for sensing the temperature in said oven space, and means responsive to said sensing means for controlling said trident valve to direct hot compressed refrigerant vapor from said compressor through said heating coil to said condenser when the temperature in said oven space is below a predetermined value and to direct said hot refrigerant vapor through said bridge pipe to said condenser when the temperature in said oven space is above a predetermined value.

Abstract
The present invention provides for a refrigerator-oven complex based on the principle of the operative circuitry of the conventional refrigerator or freezer, specifically it means the additional incorporation of an empty box with temperature conservancy equipments at a suitable quarter of the conventional refrigerator or freezer, the said additional empty box will be referred to as the oven hereafter, the high temperature evaporation tube as the exhaust of the compressor of the refrigerator or the freezer is extended into the oven, the calorific power is diffused in the oven by means of several curved tubeworks and various ways of heat-diffusion so as to afford heating for objects such as foods or temperature conservation for them. Or else the calorific power may be drawn to the chambers where hot air is required by fans so as to permit adjustment of the room (chamber) temperature, the evaporation tubes that have been treated for heat-diffusion are fed into the tubeworks of the refrigerant-cooler, thence recycled back to the compressor with the commonly known technique, the invention so claimed is characteristic in best exploitation of the calorific power that has been so far left over as remanets roving in the atmosphere so as to reduce waste of thermal energy without affecting the normal running operation of the refrigeration, nor will it incur increase in electric power consumptions.
