Title: Indicating circuit of combustion device
Inventor: MURAKAMI SHIGERU
IPC: F23N5/26
Filed: 1984-06-20
Abstract: PURPOSE:To obtain a display circuit, which is effective in case of the limited exterior space and under the condition, that the application of many light emitting elements is not allowed from the viewpoint of artistic design, and the like by a method wherein the luminescent color of a single light emitting diode, which contains a plurality of light emitting elements, is changed-over in order to indicate normal state and abnormal state. CONSTITUTION:When a combustion device is put into the state of ignition failure due to the shortage of fuel oil or the like, a reset circuit 6 turns to be in the actuating state after the elapse of a predetermined period of time and a transistor 7 is driven to conduction. The conduction of the transistor 7 causes to flow current in a light emitting element 9 in order to bring in a light emitting state. Simultaneously, a signal is supplied from the reset circuit 6 to a temperature detection circuit 2 to bring it into a standstill state. As a result, a pre-purging timer circuit 4 is also brought into a standstill state, resulting in driving a transistor 5 to nonconduction and consequently causing to stop current in a light emitting element 8 in order to bring in a state to stop light emission. In other words, the luminescent color of the light emitting diode is changed-over from ''green'' to ''red'' and indicates the abnormal state.

Abstract: PURPOSE:To obtain the stable warmth and comfortableness regardless of the room temperature by connecting a temperature setting changing unit and a room temperature detecting unit, changing the temperature setting change width in response to the room temperature, and making the change width smaller as the room temperature becomes lower. CONSTITUTION:When the temperature is set in a temperature adjusting unit 5, a temperature setting changing unit 6 feeds an output to change the preset temperature to the high temperature side in response to the input from a room temperature sensor 7.

After the fixed time elapses, the changing unit 6 changes the set temperature to the low temperature side in response to the input of the sensor 7 and sends it to the control unit 4 to keep this temperature for a fixed time, thus temperature setting changes are periodically repeated. This temperature setting width is made 4 deg. at the room temperature of 17 deg. or higher, 3 deg. at 13 deg.-17 deg., and 2 deg. at the room temperature lower then 13 deg.. The stable warmth and comfortableness can be thereby obtained regardless of the room temperature.
