Abstract

A thermostatic air conditioner control for use with individual unit air conditioners having a thermostatic switch disposed at a location remote from the air conditioner. The control includes circuitry interposed between the air conditioner and a source of electrical energy operative a selected time interval after closure of said thermostatic switch to energize a socket in which the air conditioner is plugged, and operative a selected time interval after opening of said thermostatic switch to de-energize the socket.

Claims

1. A thermostatic air conditioner control adapted for use with individual unit air conditioners comprising in combination:

means for connecting said control to a source of electrical energy;

socket means adapted to rEceive the leads of said air conditioner unit;

switching circuit means adapted to selectively interconnect said source connecting means and said socket means to energize said socket means and, thereby, said air conditioner unit;

said switching circuit means including first temperature sensitive switching means responsive to surrounding ambient temperatures and actuated in response to a selected ambient temperature;

timing means energized in response to the operation of said temperature sensitive switching means and operative a selected time interval after energization thereof;

relay means connected to be energized in response to operation of said timing means;

relay switch means operative in response to energization of said relay means for interconnecting said source connecting means and said socket means to energize said socket means.

2. A control as claimed in claim 1 wherein said source connecting means is a plug adapted to be inserted into an A.C. wall outlet connected to a source of A.C. voltage.

3. A control as claimed in claim 2 wherein said plug is connected to the primary of a step down transformer, and wherein said socket and said relay switch means are connected in series with each other across the primary of said step down transformer.

4. A control as claimed in claim 3 wherein said temperature responsive switching means and said timing means are connected in series with each other and across the secondary of said step down transformer.

5. A control as claimed in claim 4 including control switch means connected in series with said relay means across the secondary of said step down transformer, said control switch means closing in response to operation of said timing means to energize said relay means.

6. A control as claimed in claim 5 wherein said temperature sensitive switching means is located remotely from the remainder of said control, whereby said control is adapted to be operative in response to selected ambient temperature at a location remote therefrom and remote from the air conditioner unit connected to said socket means.

7. A control as claimed in claim 6 wherein said temperature responsive switching means is a thermostat and includes means for selecting the ambient temperature at which said temperature responsive switching means closes.

8. A control as claimed in claim 7 wherein said timing means includes a time delay relay connected in series with said temperature responsive switching means, said time delay relay being operative a selectable time interval after closure of said temperature responsive switching means to close said control switch means, and being operative a selected time interval after opening of said temperature sensitive switch means to open the contacts of said control switch means.

9. A thermostatic air conditioner control for controlling the operation of a room air conditioner in response to variations in the temperature of the room at a point remote from said air conditioner comprising in combination:

a thermostatic switch disposed at a location remote from said air conditioner for sensing ambient temperatures at said location, said thermostatic switch including means for selecting a desired temperature and switching means closing in response to said sensed ambient temperature being above said selected temperature and opening in response to said sensed ambient temperature being below said selected temperature;

circuit means electrically connecting said switching means in series with a time delay relay, said series combination of said switching means and said time delay relay being connected across the secondary of a step down transformer;

means connecting the primary of said step down transformer to a source of electrical energy;

a relay coil, and time delay switch contacts operatively associated with said time delay relay, said time delay relay contacts and said relay coil being connected in series with each other across said secondary of said step down transformer, sAid time delay relay operative a selected time interval after closing of said thermostatic switch to close said time delay contacts and energize said relay coil;

normally open relay contacts closing in response to the energization of said relay coil, said relay contacts being connected in series with a socket across the primary of said step down transformer;

whereby said socket is connected to said source of electrical energy a selected time interval after closure of said thermostatic switch and is disconnected from said source of electrical energy a selected time interval after opening of said thermostatic switch to energize and deenergize a room air conditioner connected to said socket.
