Description
REFRIGERATORCONTROLMETHOD
This invention is related to a control method developed to eUminate the problem of cooling failure at low ambient temperature in refrigerators, preferably dual- compartment refrigerators.
In refrigerators, preferably dual-compartment refrigerators having one refrigerating compartment and one freezer, compressor is activated by a thermostat located in the refrigerating compartment. Since the thermostat is affected by outside temperature, when the outside temperature is low, the compressor is not activated properly and as a result sufficient cooling is not provided. According to the known techniques, to eliminate the problem of cooling failure at low outside temperature, temperature of the refrigerating compartment is increased in a short period of time so that the thermostat can activate the compressor.
In the German Patent Application DE4210603, a thermostat which senses the outside air temperature activates the heater in the refrigerating compartment when the temperature falls.
In the German Patent Application DE4208144, a heater resistance serially connected to a bulb, and alternatively a second bulb of long-life and low-power consumption type instead of heater resistance is used.
According to the International Patent Applications WO9849507 and WO0075585, power of the bulb is decreased by resistive elements, and thus it is used both for heating and illuminating purposes.
In the German Patent Application DE19634687, when the freezing compartment is to be cooled rapidly, for example; when the door of freezing
compartment is opened and closed, the thermostat is activated at low temperature and the bulb is turned on.
In the USA Patent US4375750, in an absorption refrigerator, to prevent insufficient or excessive amount of cooling gas from entering the freezing compartment and the refrigerating compartment at low temperatures, when the disconnect period of the thermostat for the refrigerating compartment the thermostat placed in the freezing compartment is activated and thus cooling gas is sent to the freezing compartment at short intervals.
The objective of this invention is to provide a simple and low-cost control method which will enable refrigerators to perform cooling at low ambient temperatures.
The cooling control method which is designed to achieve this objective is shown in the appended figures.
Figure 1 — is a schematic view of a refrigerator.
Figure 2 - is a flow diagram of a cooling control method in which temperatures of the freezing compartment and the refrigerating compartment are controlled independently.
Figure 3 — is a flow diagram of a cooling control method in which firstly the temperature of the freezing compartment and later the temperature of the refrigerating compartment are controlled consecutively. Figure 4 - is a flow diagram of a cooling control method in which firstly the temperature of the refrigerating compartment and later the temperature of the freezing compartment are controlled consecutively.
Each part shown in the figures has a unique number and the equivalents of these numbers are stated below:
1. Refrigerator
2. Refrigerating compartment
3. Freezing compartment 4. Main thermostat
5. Safety thermostat
6. Compressor
Refrigerators (1) include a refiigerating compartment (2) where foods are stored; a freezing compartment (3) where foods are frozen and stored; a main thermostat (4) placed into the refrigerating compartment (2); a safety thermostat
(5) placed into the freezing compartment (3), which is connected parallelly to the main thermostat (4), preferably selected as bi-metal; and a compressor (6).
According to the method mentioned above, refrigerator (1) control process (100) is started in order to ensure that the temperature (TF) of the freezing compartment (3) and the temperature (TR) of the refrigerating compartment (2) are controlled independently. From these temperatures, while the temperature (TF) of the freezing compartment (3) is controlled, the temperature (TF) of the freezing compartment (3) is compared with threshold value (TF-threshoid) of the temperature (TF) of the freezing compartment (3) (101). If the temperature (TF) of the freezing compartment (3) is higher than the threshold value (Tr-hreshoid) of the temperature (TF) of the freezing compartment (3)
safety thermostat (5) enables current passage . With this current compressor (6) is activated (103) and it is returned to starting point (100). If the temperature (TF) of the freezing compartment (3) is lower than the threshold value (TF-threshoid) of the temperature (TF) of the freezing compartment (3) (TF<TF-thresiιoid), safety thermostat (5) cuts the current (104) and it is returned to the starting point (100). While the temperature (TR) of the refrigerating compartment (2) is controlled, the temperature (TR) of the refrigerating compartment (2) is compared with uppermost value (TR-ιφper) of the
temperature interval of the refrigerating compartment (2) (105). If the temperature (TR) of the refrigerating compartment (2) is higher than the uppermost value (TR. u er) of the temperature (TR) interval of the refrigerating compartment (2) (TR>TR. iφ er), the main thermostat (4) enables current passage (106). With this current the compressor (6) is activated (103) and it is returned to the starting point (100). If the temperature (TR) of the refrigerating compartment (2) is lower than the uppermost value (TR.„pper) of the temperature (TR) interval of the refrigerating compartment (3) (TR<TR-Upper), the temperature (TR) of the refrigerating compartment (2) is compared (107) with the lowermost value (TR-ιower) of the temperature interval of the refrigerating compartment (2). If the temperature (TR) of the refrigerating compartment (2) is higher than the lowermost value (T -IOWCΓ) of the temperature (TR) interval of the refrigerating compartment (2) (TR>TR-lower), H is returned to the step (105) where it is compared with the uppermost value (TR- npper) of the temperature (TR) of the refrigerating compartment (2). If the temperature (TR) of the refiigerating compartment (2) is lower than the lowermost value (TF-iower) of the temperature (TR) interval of the refrigerating compartment (2) (TR<TR-lower), the main thermostat (4) cuts (108) the current and it is returned to the starting point (100).
In this refrigerator (1) control method, when the main thermostat (4) and the safety thermostat (5) simultaneously cut the current, compressor (6) stops.
According to a different embodiment of the invention, refrigerator (1) control process is started (200) in order to ensure that firstly the temperature (TF) of the freezing compartment (3) and later the temperature (TR) of the refrigerating compartment (2) are controlled consecutively. The temperature (TF) of the freezing compartment (3) is compared (201) with threshold value (TF-threshoid) of the temperature (TF) of the freezing compartment (3). If the temperature (TF) of the freezing compartment (3) is higher than the threshold value (TF-threshoid) of the temperature (TF) of the freezing compartment (3) (TF>TF-t res oid), safety thermostat
(5) enables (202) current passage . With this current compressor (6) is activated (203) and it is returned to starting point (200). If the temperature (TF) of the freezing compartment (3) is lower than the threshold value (TF-ihreshoid) of the temperature (TF) of the freezing compartment (3)
safety thermostat (5) cuts the current (208). The temperature (TR) of the refrigerating compartment (2) is compared with uppermost value
of the temperature (TR) interval of the refiigerating compartment (2) (204). If the temperature (TR) of the refiigerating compartment (2) is higher than the uppermost value (TR-Ϊlpper) of the temperature (TR) interval of the refrigerating compartment (2)
the main thermostat (4) enables current passage (205), with this current the compressor (6) is activated (203) and it is returned to the starting point (200). If the temperature (TR) of the refrigerating compartment (2) is lower than the uppermost value (TR-upper) of the temperature (TR) interval of the refrigerating compartment (2) (TR<TR.upper), the temperature (TR) of the refrigerating compartment (2) is compared with lowermost value (TR-l0wer) of the temperature interval of the refrigerating compartment (2) (206). If the temperature (TR) of the refrigerating compartment (2) is higher than the lowermost value (TF-IO -T) of the temperature (TR) interval of the refrigerating compartment (2) (T >TR-lower), it is returned to the starting point (200). If the temperature (TR) of the refrigerating compartment (2) is lower than the lowermost value (TR-loWer) of the temperature (TR) interval of the refrigerating compartment (2) (TR<TR.l0Wer), the main thermostat (4) cuts (207) the current and it is returned to the starting point (200). In this refrigerator (1) control method, when the main thermostat (4) and the safety thermostat (5) cut the current, the compressor (6) stops.
According to a different embodiment of the invention, refrigerator (1) control process is started (300) in order to ensure that firstly the temperature (TR) of the refrigerating compartment (2) and later the temperature (TF) of the freezing compartment (3) are controlled consecutively. The temperature (TR) of the refrigerating compartment (2) is compared with uppermost value (T ^PO of the
temperature interval of the refrigerating compartment (2) (301)Jf the temperature (TR) of the refrigerating compartment (2) is higher than the uppermost value (TR. u per) of the temperature (TR) interval of the refrigerating compartment (2) (TR>TR. upper), the main thermostat (4) enables current passage (302). With this current the compressor (6) is activated (303) and it is returned to the starting point (300).If the temperature (TR) of the refrigerating compartment (2) is lower than the uppermost value (TR-Upper) of the temperature (TR) interval of the refrigerating compartment
(2) (T <T -ιφper), the temperature (TR) of the refrigerating compartment (2) is compared with lowermost value (T .ιower) of the temperature interval of the refrigerating compartment (2) (304). If the temperature (TR) of the refiigerating compartment (2) is lower than the lowermost value (I -iower) of the temperature (TR) interval of the refiigerating compartment (2) (TR<TR-1OW?Γ), the main thermostat cuts (305) the current and it is returned to the starting point (300). If the temperature (TR) of the refrigerating compartment (2) is higher than the lowermost value (TR-lower) of the temperature (TR) interval of the refπgerating compartment (2) (TR>TR.ι0wer), the temperature (TF) of the freezing compartment
(3) is compared with threshold value (I -threshoi ) of the temperature interval of the freezing compartment (3) (306). If the temperature (TF) of the freezing compartment (3) is higher than the threshold value (TF-threshoid) of the temperature (TF) of the freezing compartment (3) (TF>TF-t reshoi ), safety thermostat (5) enables current passage (307) . With this current compressor (6) is activated (303) and it is returned to starting point (300). If the temperature (TF) of the freezing compartment (3) is lower than the threshold value (TF-thresh0id) of the temperature (TF) of the freezing compartment (3) (TF<TF-t reshoid), safety thermostat (5) cuts the current (308) and it is returned to the starting point (300). Also in this embodiment, when the main thermostat (4) and the safety thermostat (5) cut the current, the compressor (6) is stopped.
At low ambient temperatures, safety thermostat (5) is activated to ensure that sufficient cooling is provided when the main thermostat (4) fails. To make sure
that the safety thermostat (5) is activated only at low temperatures when refrigerator fails, a different working interval has been selected than the working interval of the freezing compartment (3) in normal circumstances. For example, when outside temperature falls below 5 °C, the main thermostat (4) which normally activates the compressor (6) at approximately + 3°C ~ +5°C, does not activate the compressor and as a result the temperature (TF) of freezing compartment (3) increases. However the safety thermostat (5), which has a different threshold value (I -t reshoid = - 9°C) activates the compressor and ensures that cooling is resumed. At normal or higher outside temperatures, the main thermostat (4) fulfills its duty, and since the temperature (TF) of freezing compartment (3) is lower than Tr-t res oid, the safety thermostat (5) is not activated.
