Reference numeral 201 is a telephone, and 202 is a telephone-side indoor communication device connected to the telephone 201, which is a wired or wireless indoor communication line 2
By 03, the refrigerator-side indoor communication device 18 and the telephone-side indoor communication device 202 are connected. Reference numeral 16 is an accounting device placed at a store of goods, and 17 is a communication device of the accounting device connected to the accounting device. The communication device 17 of the accounting device is
It is connected to the telephone 201 by the public line 204.

Numeral 205 is article information for the freezer transmitted via the public line 204, numeral 206 is article information displayed on the accounting apparatus 16, and numeral 207 is a telephone number of the refrigerator user input to the accounting apparatus 16. When a refrigerator user purchases an article at a store and completes accounting, the product name and price are displayed on the accounting device 16. When the user designates the product with the product name 1, the product name 3, the product name 5 and the product name n as the product to be stored in the freezer of the refrigerator, the accountant takes the product name 1, the product name 3, the product name 5 and It is input to the accounting apparatus 16 that the article with the product name n is stored in the freezer. At this time, a circle mark is displayed in front of the product name to be stored in the freezer. Further, the user informs the telephone number 207 of the refrigerator user to the accounting person in order to transmit the item information 205 to the freezer described later to the refrigerator 1 at home, and the accounting person inputs the telephone number.

When the above work is completed, the accounting device 16
Creates the product information 205 for the freezer in which the packaging form information and the weight information of the product corresponding to this product name are added to the product name to be stored in the freezer, and the communication device 17 of the accounting device makes the public line. The item information 205 for the freezer is transmitted via 204 to the telephone 201 corresponding to the telephone number 207 of the refrigerator user. After receiving the item information 205 for the freezer, the telephone 201 transmits the item information 205 for the freezer to the refrigerator-side indoor communication device 18 from the telephone-side indoor communication device 202 via the indoor communication line 203.

Reference numeral 19 is a data analysis means (see FIG. 3), which includes a product name and packaging form information corresponding to the product name from the product information 205 to the freezer inputted via the refrigerator-side indoor communication device 18.

For example, when the information that the packaging form of a certain article is a close-packed package in which the contents and the package are in close contact with each other is obtained, the product is classified as a close-packed package recorded in advance in the third recording means. The given value C (1) is determined as the packaging form corresponding numerical value Cp of the article. The packaging form corresponding numerical value Cp is a numerical value corresponding to the heat resistance or the specific heat, and represents the coldness per unit weight.

When the calculating means 22 receives the weight information from the data analyzing means 19 and the packaging form corresponding numerical value Cp from the numerical value judging means 21, the calculating form 22 receives the packaging form corresponding numerical value Cp.
And the product of mass. The product of the packaging form corresponding numerical value Cp and the mass is a numerical value corresponding to the heat capacity and represents the coldness of each product. The calculating means 22 calculates the product of the packaging form corresponding numerical value Cp and the mass for all the products, and then sums the products of the packaging form corresponding numerical value Cp and the mass of all the products to obtain a total value X.

1, ΔT2, ΔT3, and the temperature decrease width ΔT4 corresponding to the temperature increase when the refrigerating compartment door or the freezing compartment door is opened and closed are recorded. The precooling temperature determination means 24 refers to the membership function and the temperature decrease width for the membership function, and determines the temperature decrease width ΔT from the following equation 1.

[Equation 1] ΔT = (ΔT1 × M1 (X) + ΔT2 × M2 (X) + ΔT3 × M3 (X)) / (M1 (X) + M2 (X) + M3 (X)) + ΔT4 ... Equation 1 Although the temperature decrease width ΔT is determined from the membership function in the above description, a function or a correspondence table that directly determines the temperature decrease width ΔT from the total value X may be used.

The precooling temperature determination means 24 determines the precooling set temperature TSET2 from the following equation 2 with respect to the freezer compartment setting temperature TFSET input from the input means 10.

In S13, the operation control means 15 compares the freezing compartment temperature with the precooling lower limit temperature TFL2, and when the freezing compartment temperature is equal to or lower than the precooling lower limit temperature TFL2, the freezing compartment is considered to be cooled, and the process proceeds to S16. If the freezing room temperature is higher than the freezing room lower limit temperature TFL2, the process proceeds to S14.

In S14, the operation control means 15 determines the elapsed time TIME from the start of the operation of the freezer compartment fan 35.

If less than (F), the process proceeds to S15. In S15, when the pre-cooling operation control means 25 receives the pre-cooling release signal, the pre-cooling operation is terminated as if the storage of the product has started. When the precooling operation control means 25 has not received the precooling cancellation signal, the process returns to S13. In S16, the operation control means 15 stops the freezer compartment fan 35, and the three-way valve 40
Is switched to the RF direction, and the process proceeds to S17.

In S17, the operation control means 15 compares the refrigerating compartment temperature with the refrigerating compartment upper limit temperature TRH. When the refrigerating compartment temperature is equal to or higher than the refrigerating compartment upper limit temperature TRH, the operation proceeds to S18, and the refrigerating compartment temperature is kept. When the temperature is lower than the upper limit temperature TRH, it is considered that the freezer compartment has already been cooled, and the process proceeds to S22. In S18, the operation control means 15 operates the compressor 4 at a higher rotation speed than in the normal operation, and the refrigerator compartment fan 3 is operated.

In S19, the operation control means 15 compares the refrigerating compartment temperature with the refrigerating compartment lower limit temperature TRL, and when the refrigerating compartment temperature is equal to or lower than the refrigerating compartment lower limit temperature TRL, the freezing compartment is sufficiently cooled for precooling. If it is determined that the temperature of the refrigerating compartment is higher than the lower limit temperature TRL of the refrigerating compartment, the process proceeds to S20.

In S20, the operation control means 15 determines the elapsed time TIME from the start of the operation of the refrigerating compartment fan 34.

If less than (R), the process proceeds to S21. In S21,
When the pre-cooling operation control means 25 receives the pre-cooling release signal, the pre-cooling operation is ended assuming that the storage of the articles has started. When the precooling operation control means 25 has not received the precooling cancellation signal, the process returns to S19.

In S22, the operation control means 15 stops the compressor 4 and the refrigerator compartment fan 34, and proceeds to S23. In S23, when the pre-cooling operation control means 25 receives the pre-cooling release signal, the pre-cooling operation is ended assuming that the storage of the articles has started. When the precooling operation control means 25 has not received the precooling cancellation signal, the process returns to S11. After the pre-cooling operation is completed, the pre-cooling operation control means 25 replaces the pre-cooling set temperature TFSET2 recorded in the first recording means with the freezing room set temperature TFSET, replaces the pre-cooling upper limit temperature TFH2 with the freezing room upper limit temperature TFH, and performs the pre-cooling. The lower limit temperature TFL2 is replaced with the freezer compartment lower limit temperature TFL, and the operation control means 15 is caused to perform normal operation control as shown in FIG.

As described above, in the pre-cooling operation, the freezing compartment is exclusively cooled for the predetermined time TS (F) so that the freezing compartment temperature becomes lower than the normal set value. Further, as described above, by switching the direction of the three-way valve with reference to the elapsed time TIME (R) or TIME (F) from the start of the operation of the fans in the refrigerating room and the freezing room, either the refrigerating room or the freezing room can be operated. It is possible to avoid an unacceptably high temperature inside the refrigerator while the other is being cooled.

An example of temperature changes in the refrigerating compartment and the freezing compartment before and after the articles are stored in the freezing compartment by performing the above-described precooling operation will be described with reference to FIG. In FIG. 9, the article information 205 to the freezer is transmitted to the refrigerator 1 while the refrigerating room is being cooled, and the pre-cooling operation is started. At this time,

The high rotation speed operation of the machine 4 and the freezer compartment fan 35 are operated. Operation control is S1
3, the operation control means 15 compares the freezer compartment temperature with the precooling upper limit temperature TFH2. The freezing room temperature is the precooling upper limit temperature T
Since it is higher than FH2, the operation control proceeds to S14.

At S14, the elapsed time TIME (F) from the start of operation of the freezer compartment fan 35 is set to a predetermined time TS (F).
And the elapsed time TIME (F) is equal to the predetermined time TS
When it is determined that it is smaller than (F), the process proceeds to S15. S15
Then, it is confirmed whether the pre-cooling release signal is received by the pre-cooling operation control means 25, and if the pre-cooling release signal is not received, the process returns to S13. The precool release signal is the precool operation control means 2
While the time has not reached 5, the control is repeated between S13 and S15, and the cooling of the freezer is continued. When the pre-cooling lower limit temperature TFL2 is not reached and the pre-cooling release signal reaches the pre-cooling operation control means 25, the pre-cooling operation ends and the normal operation is resumed.

When the pre-cooling operation control is performed as described above, the air in the freezing chamber and the heat insulating wall 45 around the freezing chamber are cooled, and as shown by the solid line in FIG. The temperature drops sufficiently. The air in the freezer compartment flows out of the refrigerator during storage and the temperature rises. However, the heat insulating wall 45 around the freezer compartment is cooled to a temperature lower than usual by the pre-cooling operation, and therefore is shown by the dotted line in FIG. Compared to the temperature change when the pre-cooling operation is not performed, the freezing room temperature at the end of storage is kept low, and it is possible to suppress melting of the frozen object and deterioration of the material quality of the object due to melting.
Further, since the heat insulating wall 45 around the freezing compartment is cooled to a temperature lower than usual by the pre-cooling operation, the heat insulating wall 45 around the freezing compartment accumulates while the refrigeration cycle 8 does not cool the freezing compartment. The newly stored articles are cooled by the generated cooling power. In the above description, the heat insulating wall 45 around the freezer compartment is used as the cool storage means, but a cool storage effect is obtained by using a part of the heat insulating wall 45 as a heat storage material or by installing a container having a heat capacity in the freezer compartment. May be increased.

As described in the first embodiment, in the refrigerator of the present embodiment, the temperature of the freezer is controlled by the time taken for the user of the refrigerator who purchased the article to return from the purchase store to his home. By lowering the temperature inside the refrigerator set in advance, it is possible to suppress an increase in temperature inside the refrigerator when the articles are stored in the refrigerator, and it is possible to prevent the quality of the articles stored in the freezer from being deteriorated. In addition, the refrigerator of the present embodiment calculates, based on the provided packaging form information or weight information, how low the temperature is from the preset internal temperature. Different from the one that changes the temperature setting inside the freezer as predicted from the above, the inside temperature does not rise too much and the quality of the goods is not impaired, and the inside temperature drops too much and extra power is used. There is no burden on the user.

In the above description, the pre-cooling operation in the case of storing articles in the freezing room has been described. Next, the pre-cooling operation in the case of storing articles in the refrigerating room will be described.

The data analysis unit 19 transmits the packaging form information and the weight information from the article information to the refrigerating room input via the refrigerator-side indoor communication device 18 to the numerical determination unit 21 and the calculation unit 22.

As in the case of storing articles in the freezer, the numerical value judging means 21 judges the numerical value Cp corresponding to the packaging form, and the calculating means 22 calculates the total value X from the weight information and the packaging form corresponding numerical value Cp. Further, the precooling temperature determination means 24 determines the precooling set temperature TSET2 from the total value X. Further, the precooling temperature determination means 24 determines a precooling upper limit temperature TFH2 higher than the precooling set temperature TFSET2 by a predetermined temperature and a precooling upper limit temperature TFL2 lower than the precooling set temperature TFSET2 by a predetermined temperature.

After the above work, the precooling operation control means 25 performs the precooling operation control according to the above-mentioned flowchart shown in FIG. 8 via the operation control means 15. An example of temperature changes in the refrigerating room and the freezing room in the pre-cooling operation will be described with reference to FIG.

In FIG. 10, the pre-cooling operation is started while the refrigerating compartment is being cooled. In S11, the operation control means 15 compares the freezer compartment temperature with the precooling upper limit temperature TFH2. Since the freezer compartment temperature is higher than the precooling upper limit temperature TFH2, the control proceeds to S12. In S12, the operation control means 15 switches the three-way valve to the F direction, and the compressor 4
The high rotation speed operation and the freezer compartment fan 35 operation are performed. Next, the process proceeds to S13, but since the freezing room temperature is equal to or higher than the precooling lower limit temperature TFL2, the process proceeds to S14. In S14, the elapsed time TIME (F) from the start of operation of the freezer compartment fan 35 is compared with the predetermined time TS (F).
If (F) is smaller than the predetermined time TS (F), S1
Go to 5.

In S15, it is confirmed whether or not the precooling cancellation signal is received by the precooling operation control means 25. If the precooling cancellation signal is not received, the process returns to S13. While the pre-cooling release signal has not reached the pre-cooling operation control means 25, the control is repeated between S13 and S15 to continue cooling the freezer compartment. When the precooling lower limit temperature TFL2 is not reached, the storage is started, and the precooling release signal indicates the precooling operation control means 25.
When reaches, the pre-cooling operation ends and the normal operation is resumed.

When the pre-cooling operation control is performed as described above, FIG.
A change in temperature of the refrigerating room and the freezing room occurs as indicated by a solid line at 0. Further, the temperature change when the pre-cooling operation is not performed is shown by the dotted line in FIG. In the example of FIG. 10, the refrigerating compartment temperature exceeds the refrigerating compartment upper limit temperature TRH at the end of storage regardless of whether the precooling operation control is performed or not. However, focusing on the freezer temperature,
When the pre-cooling operation is not performed, the freezing room temperature exceeds the freezing room upper limit temperature TFH while the refrigerating room is being cooled.
On the other hand, when performing the pre-cooling operation, the temperature of the freezing room does not exceed the freezing room upper limit temperature TFH because the freezing room is pre-cooled in advance, and the frozen product is melted and the product accompanying melting is melted. Material deterioration can be suppressed.

If the refrigerating compartment temperature is higher than the refrigerating compartment lower limit temperature TRL, the process proceeds to S121. In S121,
When the pre-cooling operation control means 25 receives the pre-cooling release signal, the pre-cooling operation is ended assuming that the storage of the articles has started. When the precooling operation control means 25 has not received the precooling cancellation signal, the process returns to S120.

When the storage is started when the freezer compartment temperature does not reach the precooling lower limit temperature TFL2, the precooling release signal reaches the precooling operation control means 25,
The pre-cooling operation ends and the normal operation is resumed.

When the pre-cooling operation control is performed as described above, the temperature change in the freezer compartment as shown by the solid line in FIG. 16 occurs from the start of storage to the end of storage. Since the air in the freezer compartment and the heat insulating wall 45 around the freezer compartment are cooled more by the pre-cooling operation than during the normal operation, the temperature change at the end of storage is greater than the temperature change in the case without the pre-cooling operation shown by the dotted line in FIG. The temperature of the freezer can be kept low, and it is possible to suppress the melting of the already stored and frozen goods and ice, and the deterioration of the materials of the goods due to the melting.

Even if it is stored in the refrigerator, all or most of the cooling air can be supplied to the refrigerating room to quickly reduce the temperature inside the refrigerating room, and the temperature inside the freezing room also deteriorates the quality of the stored articles. It does not raise the temperature so much.

In the above-mentioned first and second embodiments, the signal issued when the precool release button 44 is pressed is the precool release signal. However, the door switch of the refrigerating room or the freezing room outputs the door open signal for a predetermined time. When the above transmission is continued, this door opening signal may be regarded as the precooling cancellation signal. Further, if the temperature detected by the refrigerating compartment temperature sensor 30 rises to a predetermined value or more after the opening signal of the refrigerating compartment door switch 42 is transmitted, the detected temperature rise may be regarded as the precooling release signal. Furthermore, after the opening signal of the freezer compartment door switch 43 is transmitted, if the temperature detected by the refrigerating compartment temperature sensor 31 rises above a predetermined value, the detected temperature rise may be regarded as a precooling release signal.

Further, a CCD camera, an infrared sensor or the like may be provided in the refrigerator to directly detect the storage of the articles, and the increase information of the articles stored in the cabinet may be regarded as the precooling release signal. Alternatively, a label that can be detected by a predetermined sensor may be attached to the stored article, the storage of the article in the refrigerator may be detected by the predetermined sensor, and the detection information may be regarded as the precooling release signal. Further, the refrigerator may be provided with a timer, and the precool release signal may be transmitted from the timer when a predetermined time has elapsed from the start of the precool operation.

However, when the pre-cooling release button 44 is used in place of the door open signal or the internal temperature, the person who lives at home from the time when the purchaser returns after sending the article information from the shop. If the refrigerator door is opened for a certain period of time or more and the temperature inside the refrigerator rises, there is a possibility that the operation at the preset temperature inside the refrigerator may be started before the required temperature inside the refrigerator is reached.

The third embodiment of the present invention addresses the above problem, and a precooling operation holding switch is installed in the refrigerator as an operation holding means. When the pre-cooling operation holding switch is pressed, a holding signal is sent to the pre-cooling operation control means 2
