Abstract

An air conditioner control circuit having a thermostat for automatically causing the air conditioner to be deenergized at predetermined low temperatures and including a timing device causing the room air to be periodically delivered to the thermostat of the air conditioner for providing improved automatic thermostatic control of the air conditioner. The means for bringing the air to the thermostate may comprise an automatic timer for periodically energizing the fan of the air conditioner at temperatures below the predetermined low.

Claims

1. An air conditioner comprising:

means for conditioning air;

air-circulating means for circulating ambient air in association with said conditioning means to be conditioned thereby;

control means for sensing the condition of the air to be conditioned for controlling the operation of said conditioning means and said air-circulating means, said control means including a thermostat switch for terminating operation of said air-circulating means as a result of the temperature of air in heat transfer association with said sensing means being below a preselected temperature; and

means for periodically operating said air-circulating means to sample the ambient air by bringing ambient air to control means periodically for sensing the condition thereof notwithstanding the temperature of air in heat transfer association with said thermostat switch being below said preselected temperature.

2. The air conditioner of claim 1 wherein said conditioning means comprises air-refrigerating means.

3. The air conditioner of claim 1 wherein said means for periodically operating said air-circulating means is connected in parallel wiTh said thermostat switch to operate said air-circulating means.

4. The air conditioner of claim 1 wherein said means for periodically operating said air-circulating means comprises a motor driven timer.

5. The air conditioner of claim 1 wherein said control means include a first thermally responsive switch means for controlling the operation of said conditioning means, and a second thermally responsive switch means for controlling the operation of said air-circulating means.

6. The air conditioner of claim 5 wherein said means for periodically operating said air-circulating means comprises a timer motor, said second thermally responsive switch means concurrently energizing said timer motor and deenergizing the air-circulating means, and means responsive to a preselected time of operation of said timer motor for energizing said air-circulating means.

7. The air conditioner of claim 1 wherein said control means is arranged to operate said air-circulating means independently of said means for periodically operating said air-circulating means.

8. An air conditioner comprising:

a compressor;

a condenser;

an evaporator;

air-circulating means for circulating air in heat transfer relationship with said condenser and said evaporator and from the evaporator to an enclosure;

means for selectively energizing said compressor and air-circulating means;

thermally responsive means for deenergizing said compressor at a first preselected temperature and deenergizing said air-circulating means at a second preselected temperature below said first preselected temperature; and

control means for sampling ambient air periodically including means for energizing said air circulating means periodically notwithstanding the temperature being sensed by said thermally responsive means being below said second preselected temperature.

9. The air conditioner of claim 8 wherein said control means includes a timer means.

10. The air conditioner of claim 9 wherein said control means is controlled by said thermally responsive means.

11. The air conditioner of claim 8 wherein said thermally responsive means includes a first thermostat switch for controlling operation of the compressor and a second thermostat switch for controlling operation of the air circulating means.

12. The air conditioner of claim 11 wherein said second thermostat switch controls operation of said control means.
