Abstract
There is provided a regulator for wall thermostats. The regulator is operated by a timer, and provides a warm air stream upwardly beneath a thermostat to cause the thermostat to lower the house temperature between specific hours, such as at night, and cuts off the warm air stream for the remainder of the day. A housing defines an air passage which has manual means for restricting it to a greater or lesser degree. Illumination and heating means are provided within the housing which simultaneously heats the air to promote convective flow upwardly, and illuminates the manual means.
Claims7
A regulator for wall thermostats, comprising:
- a housing adapted to be affixed to a wall under a thermostat, the housing defining within it a passage for air, the passage having an inlet and an outlet with the inlet situated below the outlet,
- a manually rotatable member at least partly translucent and mounted to the housing in the path defined by said passage, the rotatable member defining a passageway which may be adjusted by rotating the member to positions between that of alignment with said passage and that of blocking said passage;
- the rotatable member including two part-cylindrical partitions each covering about 90.degree. of arc, and being spaced apart by intervals of about 90.degree., the housing defining a cylindrical guideway in which said partitions can rotate, the guideway being part of said passage, the passage having side walls which intersect the guideway so as to open through about 90.degree. of the cylinder, whereby each partition is able to assume a position in which the passage is completely blocked,
- and means including a light source within the passageway of the member for simultaneously (a) heating the air within said passageway thus promoting convective flow from the inlet to the outlet, and (b) illuminating said rotatable member.
