Description

AUTOMATIC QUICK FREEZING
The present invention relates to automatically performing the quick freezing operation realized for the quick freezing of the food placed in the freezer compartment of the refrigerators without effecting the already frozen food present in the said compartment.
The methods that are controlled by the user in order to quick freeze the food placed in the freezer compartment without effecting the previously frozen food present in the said compartment, are already known.
In the quick-freeze methods controlled by the user, the freezer compartment is cooled before a food at a temperature that is higher than the interior temperature of the freezer compartment is put into the said compartment, in order to accelerate freezing and to avoid the spoiling of the frozen food in the freezer compartment, by the increase of temperature caused by the food to be placed in the freezer compartment being at temperatures higher than the temperatures of the food that are already present in the freezer, thus minimizing the rise in temperature in the compartment. When the quick freezer button is pressed by the user, the quick-freezing operation starts. By running the compressor and the freezer compartment fan at 100% capacity, the freezer compartment is cooled up to values which are much more lower than the preset values. When the freezer compartment is cooled to a certain temperature (approximately -27°C) the user is warned by an audible or visual signal, to place the food in the freezer compartment. Then, the compressor and the fan are operated at 100% capacity for a certain period or until a certain temperature is attained, thus completing the quick freezing operation.
In another method, the quick freezing operation is carried out by running the compressor and the fan at 100% capacity when the quick freezing function is started, until the user stops the said function. The user has to know how and when to use the quick freeze function. If the user puts warm food into the freezer compartment without starting the quick freeze function, the said warm food causes an unwanted increase in the temperature of the frozen food already present in the freezer and this also creates an inconvenience for the user.
The object of the present invention is to carry out the quick freeze function employed for the quick freezing of the food placed in the freezer compartment of the refrigerators without having any negative impact on the frozen food already present in the said compartments, automatically and independently from the user.
The automatic quick freezing realized to attain the object of the present invention is illustrated in the attached drawings, wherein:
Figure 1, is the general view of the refrigerator;
Figure 2, is the flow diagram showing the automatic quick freeze control; Figure 3, is the time-dependent temperature distribution graphic, of the freezer compartment.
The components shown in the drawings have the following numbers;
1. Freezer compartment
2. Quick freeze compartment 3. Freezer compartment sensor
4. Quick freeze compartment sensor
In the refrigerator of the present invention, a "Freezer compartment sensor" (3) is provided to determine the average temperature in the freezer compartment (1) and a "Quick freeze compartment sensor" (4) in the quick freeze compartment (2). When the quick freezing is not carried on and the freezer compartment (1) door is closed, the change in the temperature values detected by the freezer compartment sensor (3) and by the quick freeze compartment sensor (4) is negligible. The quick freeze compartment sensor (4) is placed under the metal plate at the bottom of the quick freeze compartment (2). A refrigerator quick freeze function embodiment shown in Figure 2 is explained in detail below.
The user opens the freezer compartment (1) door, puts food into the quick freeze compartment (2) found in the said freezer compartment (1) and closes the freezer compartment (1) door. After these operations, the user does not interfere with the quick freeze operation and the quick freeze operation is carried out automatically.
When the freezer compartment (1) door is opened by the user, food can be put into or taken out of the freezer compartment (1). At the end of a period (tl) that starts after the freezer compartment (1) door is closed by the user and that is determined by the manufacturer, the quick freezing compartment sensor (4) in the quick freezing compartment (2) reads the value (Tl) of the temperature in the quick freezing compartment (2). At the end of step 4, after the completion of the waiting period (t2), also referred to as the test period that has been determined by the manufacturer, step 5 starts. The quick freezing compartment sensor (4) reads the temperature value (T2) in the quick freezing compartment (2) and the freezer compartment sensor (3) reads the temperature value (T3) in the freezer compartment (1) in Step 5.
In order to realize the quick freezing operation, the quick freezing compartment (2) has to attain a certain temperature value in a certain period and there should be a certain difference between the said value and that of the freezer compartment (1), at the end of the said period. In the following steps, the time and temperature values for starting the quick freezing operation are determined by using the temperature values Tl, T2 and T3 that have been determined at the above mentioned steps.
In step 6, the difference (?T3) between the temperature value (T2) in the quick freezing compartment (2) read by the quick freezing compartment sensor (4) at the end of period (t2) and the temperature value (Tl) in the quick freezing compartment (2) read by the quick freezing compartment sensor (4) at the end of period (tl) is calculated and compared with the temperature value (SI) specified by the manufacturer, and if the difference (?T3) is smaller than the temperature value (SI) specified by the manufacturer, Step 1, wherein the freezer compartment (1) door is closed starts. If the difference (?T3) between the temperature value (T2) in the quick freezing compartment (2) read by the quick freezing compartment sensor (4) at the end of period (t2) and the temperature value (Tl) in the quick freezing compartment (2) read by the quick freezing compartment sensor (4) at the end of period (tl) is greater than the temperature value specified by the manufacturer (SI), Step 7 starts.
In Step 7, the difference (?T4) between the temperature value (T2) in the quick freezing compartment (2) read by the quick freezing compartment sensor
(4) at the end of the period (t2) and the temperature value (T3) in the freezer compartment (1) read by the freezer compartment sensor (3) at the end of the period (t2) is calculated and compared with the temperature value (S2) specified by the manufacturer, and if the difference (?T4) is smaller than the temperature value (S2), specified by the manufacturer, Step 1 starts. If the difference (?T4) between the temperature value (T2) in the quick freezing compartment (2) read by the quick freezing compartment sensor (4) at the end of period (t2) and the temperature value (T3) in the freezer compartment (1) read by the freezer compartment sensor (3) at the end of period (t2) is greater than the temperature value (S2), specified by the manufacturer, Step 8 starts and the quick freezing operation starts by the activation of the compressor; and the inner temperature value of the freezer compartment (1) reaches to a value that is lower than that is set by the user. At the moment when automatic freezing starts, an indication that shows the start of the automatic quick freezing, is displayed on the refrigerator control panel indicator, in order to warn the user.
In Step 10, if the quick freezing termination period (t3) determined by the manufacturer, has been attained, the quick freezing operation is terminated in Step 13 and the refrigerator carries on its operation according to the values defined by the user. If the quick freezing termination period (t3) determined by the manufacturer, has not been attained in Step 10, the temperature value in the freezer and/or quick freezing compartment (1 and 2) is controlled in Step 11 and if the said temperature value is above that defined by the manufacturer (T6), the compressor keeps on running and the quick freezing operation continues, otherwise Step 12 starts, at the end of a waiting time (t4) defined by the manufacturer, that starts when the freezer and/or quick freezing compartment (1 and 2) temperature value drops below the value (T6) defined by the manufacturer, quick freezing is terminated in Step 13 and the refrigerator carries on its operation according to the values defined by the manufacturer.
Thus, automatic quick freezing continues until the freezer and/or quick freezing compartment (land 2) temperature drops down to a temperature value defined by the manufacturer or until the termination of the time period defined by the manufacturer. After the automatic quick freezing operation is completed the freezer compartment (1) temperatures are kept according to the values set by the user.
