Definitions
- the present invention is related to providing heating by means of an illuminating lamp, that can be controlled with a serial switch or using a button with two contacts as the button providing the internal illumination according to the position of the door and connecting a diode to one of the said contacts, in a two-door refrigerator having a freezer and a fresh food compartment.
- the compressor is stopped when the inner temperature of the fresh food compartment reaches the required level, as detected by the thermostat; and when the fresh food compartment temperature reaches a certain level, the thermostat changes its position in order to switch in the compressor.
- This rise in the temperature of the fresh food compartment can occur naturally or additional electrical heaters can be used to accelerate the warming up. The said heaters, also prevent the frost formation etc. due to the condensation in their area.
- the lamp is used as the heater and its power is reduced by means of resistive elements so that it can be used both for illuminating and for heating purposes.
- the lamp used for both illuminating and heating purposes by reducing its value using a capacitor, is disclosed.
- the capacity of the lamp can be modified depending on the value of the capacitor.
- the object of the present invention is to use the lamp also as a heater when required, without consuming much energy.
- Figure 1 is the diagram of the circuit with diode, connected to the lamp in series;
- FIG. 1 is the diagram of the circuit for the alternative switch with dual contacts.
- the lamp (2) in the fresh food compartment is used as a heater when the door is closed, this prevents the inner temperature of the said compartment from falling below a determined level and enables the normal operation of the compressor (6).
- the lamp functions as an illuminator and a heater.
- the diode (1) that is connected in series to the normal "off contact of the door button with two contacts, is used.
- the lamp (2) stays illuminated and provides a heating with the desired capacity, when the refrigerator door is closed.
- the lamp (2) is prevented from being continuously illuminated, by using a switch (4) connected in series and thus unnecessary energy consumption is avoided.
- the switch (4) In the "on" position of the said switch (4) connected in series, the lamp (2) will be kept illuminated in low capacity status no matter if the door is open or closed.In this manner heating will be realized and the refrigerator will be able to operate in normal cycle.
- the switch (4) is at "off' position, the refrigerator illumination lamp will carry on its normal function ( Figure 2).
