[0039]
FIG. 1 is a first diagram illustrating a process of transmitting article storage information to a freezer compartment for a refrigerator. The process of transmitting article storage information to the freezer compartment will be described with reference to FIG.
[0040]
In FIG. 1, 1 is a refrigerator and 18 is a refrigerator side indoor communication apparatus connected to the refrigerator. 201 is a telephone, and 202 is a telephone-side indoor communication device connected to the telephone 201. The refrigerator-side indoor communication device 18 and the telephone-side indoor communication device 202 are connected by a wired or wireless indoor communication line 203. Reference numeral 16 denotes an accounting apparatus placed in a merchandise store, and reference numeral 17 denotes an accounting apparatus communication apparatus connected to the accounting apparatus. The accounting device communication device 17 is connected to the telephone 201 via a public line 204.
[0041]
Reference numeral 205 denotes article information to the freezer transmitted through the public line 204, 206 article information displayed on the accounting apparatus 16, and 207 a refrigerator user's telephone number input to the accounting apparatus 16. When a refrigerator user purchases an article at a store and finishes accounting, the product name and price are displayed on the accounting device 16. When the user designates the product name 1, the product name 3, the product name 5, and the product name n as the products to be stored in the freezer compartment of the refrigerator, the accounting person in charge has the product names 1, 3, 3, It is input to the accounting device 16 that the article with the product name n is stored in the freezer compartment. At this time, a circle is displayed in front of the product name to be stored in the freezer. Further, in order to transmit article information 205 to a freezer, which will be described later, to the refrigerator 1 at home, the user tells the accounting person the telephone number 207 of the refrigerator user, and the accounting person inputs the telephone number.
[0042]
When the above operation is completed, the accounting device 16 creates the article information 205 to the freezer by adding the packaging form information and the weight information of the article corresponding to the commodity name to the commodity name to be stored in the freezer. The article information 205 to the freezer is transmitted from the communication apparatus 17 of the accounting apparatus to the telephone 201 corresponding to the telephone number 207 of the refrigerator user via the public line 204. After receiving the article information 205 to the freezer, the telephone 201 transmits the article information 205 to the freezer from the telephone-side indoor communication device 202 to the refrigerator-side indoor communication device 18 via the indoor communication line 203.
[0043]
Reference numeral 19 denotes data analysis means (see FIG. 3). From the article information 205 to the freezer input via the refrigerator-side indoor communication device 18, the product name, the packaging form information corresponding to the product name, and the product name are changed. Corresponding weight information is extracted and transmitted to the numerical value determination means 21 and the calculation means 22.
[0044]
Reference numeral 20 denotes third recording means (see FIG. 3), which records a rule for determining a numerical value Cp corresponding to the packaging form information, as shown in FIG. 21 is numerical value determination means, and determines a numerical value based on the rule which determines the numerical value corresponding to packaging form information.
[0045]
For example, when obtaining information that the packaging form of an article is a close-packed package in which the contents and the package are in close contact, C given to a product classified as a close-packed package recorded in advance in the third recording means The value of (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 thermal resistance or specific heat, and represents the difficulty of cooling per unit weight.
[0046]
Reference numeral 22 denotes calculation means (see FIG. 3) for obtaining the sum of products of the numerical value corresponding to the packaging form information and the weight information corresponding to the product name. When the calculation means 22 receives the weight information from the data analysis means 19 and receives the packaging form-corresponding numerical value Cp from the numerical value determination means 21, it calculates the product of the packaging form-corresponding numerical value Cp and the 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 difficulty of cooling each product. The calculation means 22 calculates the product of the packaging form corresponding numerical value Cp and the mass for all the products, then sums up the products of the packaging form corresponding numerical value Cp and the mass of all the products, and pre-cooling temperature determination means described later as the total value X Send to. The total value X is a numerical value corresponding to the heat load of the product stored in the storage chamber 3.
[0047]
Reference numeral 23 denotes fourth recording means (see FIG. 3), which records membership functions M1 (X), M2 (X), M3 (X) for the total value X as shown in FIG. Further, the temperature decrease widths ΔT1, ΔT2, and ΔT3 for the membership functions M1 (X), M2 (X), and M3 (X), and the temperature decrease width corresponding to the temperature increase when the refrigerator compartment door or the freezer compartment door is opened / closed. ΔT4 is recorded. The pre-cooling temperature determination means 24 refers to the membership function and the temperature decrease width with respect to the membership function, and determines the temperature decrease width ΔT from Equation 1 below.
[0048]
[Equation 1]
ΔT = (ΔT1 × M1 (X) + ΔT2 × M2 (X) + ΔT3 × M3 (X)) / (M1 (X) + M2 (X) + M3 (X)) + ΔT4 Equation 1
In the above description, the temperature decrease range ΔT is determined from the membership function, but a function or correspondence table that directly determines the temperature decrease range ΔT from the total value X may be used.
[0049]
The precooling temperature determination unit 24 determines the precooling set temperature TSET2 from the following equation 2 with respect to the freezer compartment set temperature TFSET input from the input unit 10.
[0050]
[Equation 2]
TFSET2 = TFSET−ΔT Equation 2
Further, the precooling temperature determination means 24 determines a precooling upper limit temperature TFH2 that is higher than the precooling set temperature TFSET2 by a predetermined temperature, and a precooling upper limit temperature TFL2 that is lower than the precooling set temperature TFSET2 by a predetermined temperature.
[0051]
Reference numeral 25 denotes precooling operation control means (see FIG. 3). The precooling operation control means 25 replaces the freezer compartment set temperature TFSET recorded in the first recording means 11 with the precool set temperature TFSET2, replaces the freezer compartment upper limit temperature TFH with the precool upper limit temperature TFH2, and The lower limit temperature TFL is replaced with the precooling lower limit temperature TFL2, and the precooling operation control is performed via the operation control means 15.
[0052]
Hereinafter, the pre-cooling operation control will be described with reference to the flowchart of FIG.
In S11, the operation control means 15 compares the freezer temperature with the precooling upper limit temperature TFH2, and if the freezer temperature is equal to or higher than the precooling upper limit temperature TFH2, the operation proceeds to S12, and the freezer temperature is lower than the precooling upper limit temperature TFH2. In step S16, it is assumed that the refrigerator compartment has already been cooled. In S12, the operation control means 15 switches the three-way valve 40 in the F direction, operates the compressor 4 at a higher rotational speed than during normal operation, operates the freezer compartment fan 35, and proceeds to S13. In S13, the operation control means 15 compares the freezer temperature with the precooling lower limit temperature TFL2, and if the freezer temperature is equal to or lower than the precooling lower limit temperature TFL2, the operation control means 15 regards that the freezer is cooled and proceeds to S16. When the freezer compartment temperature is higher than the freezer compartment lower limit temperature TFL2, the process proceeds to S14.
[0053]
In S14, the operation control means 15 compares the elapsed time TIME (F) from the start of operation of the freezer compartment fan 35 with the predetermined time TS (F), and the elapsed time TIME (F) is set to the predetermined time TS (F). F) If it is greater than or equal to, the process proceeds to S16, and if the elapsed time TIME (F) is less than the predetermined time TS (F), the process proceeds to S15. In S15, when the pre-cooling operation control means 25 has received the pre-cooling release signal, the pre-cooling operation is terminated as the product has been stored. If the precooling operation control means 25 has not received the precool release signal, the process returns to S13. In S16, the operation control means 15 stops the freezer compartment fan 35, switches the three-way valve 40 in the RF direction, and proceeds to S17.
[0054]
In S17, the operation control means 15 compares the refrigerating room temperature with the refrigerating room upper limit temperature TRH. If the refrigerating room temperature is equal to or higher than the refrigerating room upper limit temperature TRH, the operation control means 15 proceeds to S18 and the refrigerating room temperature is the refrigerating room upper limit temperature TRH. If it is less than this, it is assumed that the freezer has already been cooled, and the process proceeds to S22. In S18, the operation control means 15 operates the compressor 4 at a higher rotational speed than during normal operation, operates the refrigerator compartment fan 34, and proceeds to S19. In S19, the operation control means 15 compares the refrigerating room temperature with the refrigerating room lower limit temperature TRL. If the refrigerating room temperature is equal to or lower than the refrigerating room lower limit temperature TRL, the operation control means 15 is sufficiently cooled to precool the refrigerating room. If it is determined that the temperature of the refrigerator compartment is higher than the lower limit temperature TRL of the refrigerator compartment, the procedure advances to S20.
[0055]
In S20, the operation control means 15 compares the elapsed time TIME (R) from the start of operation of the refrigerator compartment fan 34 with the predetermined time TS (R), and the elapsed time TIME (R) is set to the predetermined time TS (R). If it is equal to or greater than (R), the process proceeds to S22. If the elapsed time TIME (R) is less than the predetermined time TS (R), the process proceeds to S21. In S21, when the pre-cooling operation control means 25 has received the pre-cooling release signal, the pre-cooling operation is terminated as the storage of the article has started. When the precooling operation control means 25 has not received the precool release signal, the process returns to S19.
[0056]
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 has received the pre-cooling release signal, the pre-cooling operation is terminated because the storage of the article has started. When the precooling operation control means 25 has not received the precool release signal, the process returns to S11. After the precooling operation, the precooling operation control means 25 replaces the precooling set temperature TFSET2 recorded in the first recording means with the freezer compartment set temperature TFSET, replaces the precooling upper limit temperature TFH2 with the freezer compartment upper limit temperature TFH, and precools. The lower limit temperature TFL2 is replaced with the freezer compartment lower limit temperature TFL, and normal operation control as shown in FIG.
[0057]
As described above, in the pre-cooling operation, the freezer compartment is exclusively cooled for a predetermined time TS (F) so that the freezer compartment temperature is lower than the normal set value. Further, by switching the direction of the three-way valve with reference to the elapsed time TIME (R) or TIME (F) from the start of operation of the fans in the refrigerator compartment and the freezer compartment as described above, either the refrigerator compartment or the freezer compartment It can be avoided that the inside temperature rises to an extent that the other is unacceptable while one is being cooled.
[0058]
An example of temperature changes in the refrigerator compartment and the freezer compartment before and after performing the above-described pre-cooling operation and storing articles in the freezer compartment 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 refrigerator compartment is being cooled, and the pre-cooling operation is started. At this time, since the freezer temperature is lower than the precooling upper limit temperature TFH2, the operation control proceeds from S11 to S12 in the flowchart of FIG. 8, the refrigerating room fan stops, and the operation control means 15 moves the three-way valve 40 in the F direction. Switching, the high speed operation of the compressor 4 and the operation of the freezer compartment fan 35 are performed. The operation control further proceeds to S13, and the operation control means 15 compares the freezer temperature with the precooling upper limit temperature TFH2. Since the freezer temperature is higher than the precooling upper limit temperature TFH2, the operation control proceeds to S14.
[0059]
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), and it is determined that the elapsed time TIME (F) is smaller than the predetermined time TS (F). Then, the process proceeds to S15. In S15, it is confirmed whether or not the precooling operation control means 25 has received the precooling release signal. If the precooling release signal has not been received, the process returns to S13. While the precooling release signal has not reached the precooling operation control means 25, the control is repeated between S13 and S15, and cooling of the freezer compartment is continued. When the pre-cooling lower limit temperature TFL2 has not been reached, the storage is started, and when the pre-cooling release signal reaches the pre-cooling operation control means 25, the pre-cooling operation is terminated and the normal operation is resumed.
[0060]
When the precooling operation control is performed as described above, the air in the freezer compartment and the heat insulating wall 45 around the freezer compartment are cooled, and as shown by the solid line in FIG. To drop. During storage, air in the freezer compartment flows out of the refrigerator and the temperature rises. However, since the heat insulating wall 45 around the freezer compartment is cooled to a temperature lower than usual by the precooling operation, it is shown by a dotted line in FIG. Compared to the temperature change when the pre-cooling operation is not performed, the freezer temperature at the end of the storage is kept low, and the frozen material can be melted and the material deterioration of the material due to melting can be suppressed. Further, since the heat insulating wall 45 around the freezer compartment is cooled to a temperature lower than usual by the pre-cooling operation, it accumulates in the heat insulating wall 45 around the freezer compartment while the refrigerating cycle 8 does not cool the freezer compartment. The newly stored article is cooled by the cooling power thus generated. In the above description, the heat insulating wall 45 around the freezer compartment is used as the cold storage means. However, by using a part of the heat insulating wall 45 as a heat storage material or installing a container with heat capacity in the freezer compartment, the cold storage effect is achieved. May be increased.
[0061]
As described in the first embodiment, in the refrigerator of this embodiment, the temperature of the freezer is set in advance by using the time until the user of the refrigerator who purchased the article returns to the home from the purchase store. It is possible to suppress the rise in the internal temperature when the article is stored in the refrigerator, and to prevent the quality of the article stored in the freezer compartment from being lowered. In addition, the refrigerator according to the present embodiment calculates how much lower the temperature from the preset internal temperature based on the given packaging form information or weight information. Unlike the case of changing the temperature setting of the freezer compartment in anticipation from the above, the internal temperature will not rise too much to impair the quality of the goods, and the internal temperature will fall too much to use excess power There is no burden on the user.
[0062]
In the above description, the pre-cooling operation for storing articles in the freezer compartment has been described. Next, the pre-cooling operation for storing articles in the refrigerator compartment will be described.
[0063]
When the user tells the accountant that a predetermined article is to be stored in the refrigerator compartment 2 at the time of checkout at the store, the article storage information in the refrigerator compartment is similar to the article information transmission process to the freezer compartment. It is transmitted to the refrigerator side indoor communication device 18 through the public line 204 and the indoor communication line 203. The data analysis means 19 transmits the packaging form information and the weight information to the numerical value determination means 21 and the calculation means 22 from the article information for the refrigerator compartment input via the refrigerator-side indoor communication device 18.
[0064]
As in the case of storing articles in the freezer compartment, the numerical value determining means 21 determines a 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. The precooling temperature determination means 24 determines a precooling upper limit temperature TFH2 that is higher than the precooling set temperature TFSET2 by a predetermined temperature and a precooling upper limit temperature TFL2 that is lower than the precooling set temperature TFSET2 by a predetermined temperature.
[0065]
After the above work, the precooling operation control means 25 performs the precooling operation control according to the flowchart shown in FIG. An example of temperature changes in the refrigerator compartment and the freezer compartment in this pre-cooling operation will be described with reference to FIG.
[0066]
In FIG. 10, the pre-cooling operation is started while the refrigerator compartment is being cooled. In S11, the operation control means 15 compares the freezer 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 S <b> 12, the operation control unit 15 switches the three-way valve in the F direction, and performs the high rotation speed operation of the compressor 4 and the operation of the freezer compartment fan 35. Next, the process proceeds to S13, but since the freezer 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 a predetermined time TS (F). If the elapsed time TIME (F) is smaller than the predetermined time TS (F), Proceed to S15.
[0067]
In S15, it is confirmed whether or not the precooling operation control means 25 has received the precooling release signal. If the precooling release signal has not been received, the process returns to S13. While the precooling release signal has not reached the precooling operation control means 25, the control is repeated between S13 and S15, and cooling of the freezer compartment is continued. When the pre-cooling lower limit temperature TFL2 has not been reached, the storage is started, and when the pre-cooling release signal reaches the pre-cooling operation control means 25, the pre-cooling operation is terminated and the normal operation is resumed.
[0068]
When the pre-cooling operation control is performed as described above, the temperature change between the refrigerator compartment and the freezer compartment as shown by the solid line in FIG. 10 occurs. Moreover, the temperature change when not performing pre-cooling operation is shown by a dotted line in FIG. In the example of FIG. 10, the refrigeration room temperature exceeds the refrigeration room upper limit temperature TRH at the end of the storage, whether or not the pre-cooling operation control is performed. However, paying attention to the freezer compartment temperature, if the precooling operation is not performed, the freezer compartment temperature exceeds the freezer compartment upper limit temperature TFH while the refrigerator compartment is being cooled. On the other hand, when the pre-cooling operation is performed, since the freezer compartment has been pre-cooled in advance, the temperature of the freezer compartment does not exceed the freezer compartment upper limit temperature TFH. Material deterioration can be suppressed.

FIG. 14 is a diagram showing the temperature changes in the refrigerator compartment and the freezer compartment, the control status of the compressor 4, the damper 27, and the blower fan 9.
[0074]
It is assumed that the compressor 4 and the blower fan 9 are stopped and the damper 27 is closed when the operation control in FIG. 13 is started. In S101, the operation control means 15 compares the refrigerating room temperature with the refrigerating room upper limit temperature TRH. If the refrigerating room temperature is equal to or higher than the refrigerating room upper limit temperature TRH, the operation control means 15 proceeds to S102 and the refrigerating room temperature is the refrigerating room upper limit temperature TRH. If it is less than this, it is considered that the refrigerator compartment has already been cooled, and the process proceeds to S104. In S102, the operation control means 15 operates the compressor 4 and the blower fan 9, opens the damper 27, and proceeds to S103. In S103, the operation control means 15 compares the refrigerating room temperature with the refrigerating room lower limit temperature TRL. If the refrigerating room temperature is equal to or lower than the refrigerating room lower limit temperature TRL, the operation control means 15 considers that the refrigerating room is cooled and proceeds to S104. If the refrigeration room temperature is higher than the refrigeration room lower limit temperature, it is determined that it is necessary to continue cooling the refrigeration room, and the process returns to S103.
[0075]
In S104, the operation control means 15 closes the damper 27, and proceeds to S105. In S105, the operation control means 15 compares the freezer compartment temperature with the freezer compartment upper limit temperature TFH. If the freezer compartment temperature is equal to or higher than the freezer compartment upper limit temperature TFH, the operation control means 15 proceeds to S106 and the freezer compartment temperature becomes the freezer compartment upper limit temperature TFH. If it is less than this, it is assumed that the freezer has already been cooled, and the process proceeds to S108. In S106, the operation control unit 15 continues the operation when the operation control unit 15, the compressor 4, and the blower fan 9 are already operated, and the compressor 4 and the blower fan 35 are stopped. If yes, start and proceed to S107.
[0076]
In S107, the operation control means 15 compares the freezer compartment temperature with the freezer compartment lower limit temperature TFL. If the freezer compartment temperature is equal to or lower than the freezer compartment lower limit temperature TFL, the operation control means 15 considers that the freezer compartment is cooled and proceeds to S108. If the freezer compartment temperature is higher than the freezer compartment lower limit temperature TFL, the process returns to S107 to continue cooling the freezer compartment. In S108, the operation control means 15 stops the compressor 4 and the ventilation fan 9, and returns to S101. By performing the operation control as described above, the temperatures of the refrigerator compartment 2 and the freezer compartment 3 fluctuate as shown in FIG. 14 when stable.
[0077]
When the user tells the accountant that a predetermined article is to be stored in the refrigerator compartment at the time of transaction at the storefront, the process of the second embodiment is similar to the process of transmitting the article storage information to the refrigerator of the first embodiment. Article information for the refrigerator is transmitted to the refrigerator-side indoor communication device 18 via the public line 204 and the indoor communication line 203. The data analysis means 19 transmits the packaging form information and the weight information to the numerical value determination means 21 and the calculation means 22 from the article storage information in the refrigerator compartment input via the refrigerator-side indoor communication device 18.
[0078]
As in the case of storing articles in the refrigerator of the first embodiment, the numerical value determination means 21 determines the numerical value Cp corresponding to the packaging form, and the calculation means 22 calculates the total value X from the weight information and the packaging form correspondence 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 that is higher than the precooling set temperature TFSET2 by a predetermined temperature and a precooling upper limit temperature TFL2 that is lower than the precooling set temperature TFSET2 by a predetermined temperature.
[0079]
After the above work, the precooling operation control means 25 performs precooling operation control according to the flowchart shown in FIG. At the start of the precooling operation, the precooling operation control means 25 replaces the freezer compartment set temperature TFSET recorded in the first recording means with the precool set temperature TFSET2, and replaces the freezer compartment upper limit temperature TFH with the precool upper limit temperature TFH2. The freezer compartment lower limit temperature TFL is replaced with the precooling lower limit temperature TFL2.
[0080]
In S111, the operation control means 15 closes the damper 27, and proceeds to S112. In S112, the operation control means 15 compares the freezer temperature with the precooling upper limit temperature TFH2, and if the freezer temperature is equal to or higher than the precooling upper limit temperature TFH2, the operation proceeds to S113, where the freezer temperature exceeds the precooling upper limit temperature TFH2. If not, it is assumed that the freezer has already been cooled, and the process proceeds to S117. In S113, the operation control means 15 continues the operation of the compressor 4 and the blower fan 9 when the compressor 4 and the blower fan 9 are already in operation, and the compressor 4 and the blower fan 9 stop. If yes, start each and proceed to S114.
[0081]
In S114, the operation control means 15 compares the freezer temperature with the precooling lower limit temperature TFL2, and if the freezer temperature is equal to or lower than the precooling lower limit temperature TFL2, the operation control means 15 is sufficiently cooled to precool the freezer. The process proceeds to S117, and if the freezer temperature is higher than the precooling lower limit temperature TFL2, the process proceeds to S115. In S115, the operation control means 15 compares the elapsed time TIME (F) from the start of operation of the blower fan 9 with the predetermined time TS (F), and the elapsed time TIME (F) is the predetermined time TS (F). In the above case, the process proceeds to S117, and when the elapsed time TIME (F) is less than the predetermined time TS (F), the process proceeds to S116. In S116, when the precooling operation control means 25 has received the precooling release signal, the precooling operation is terminated as the storage of the article has started. If the precooling operation control means 25 has not received the precool release signal, the process returns to S114.
[0082]
In S117, the operation control means 15 stops the compressor 4 and the ventilation fan 9, and progresses to S118. In S118, the operation control means 15 compares the refrigerating room temperature with the refrigerating room upper limit temperature TRH. If the refrigerating room temperature is equal to or higher than the refrigerating room upper limit temperature TRH, the operation control means 15 proceeds to S119 and the refrigerating room temperature is the refrigerating room upper limit temperature TRH. If it is less than that, it is assumed that the freezer has already been cooled, and the process proceeds to S122. In S119, the operation control means 15 opens the damper 27, operates the compressor 4 and the blower fan 9, and proceeds to S120.
[0083]
In S120, the operation control means 15 compares the refrigerating room temperature with the refrigerating room lower limit temperature TRL. If the refrigerating room temperature is equal to or lower than the refrigerating room lower limit temperature TRL, the operation control means 15 is sufficiently cooled to precool the refrigerating room. The process proceeds to S122, and if the refrigerator compartment temperature is higher than the refrigerator compartment lower limit temperature TRL, the process proceeds to S121. In S121, when the pre-cooling operation control means 25 has received the pre-cooling release signal, the pre-cooling operation is terminated as the article has been stored. When the precooling operation control means 25 has not received the precool release signal, the process returns to S120. In S122, when the pre-cooling operation control means 25 has received the pre-cooling release signal, the pre-cooling operation is terminated as the storage of the article has started. If the precooling operation control means 25 has not received the precool release signal, the process returns to S111.
[0084]
After the precooling operation, the precooling operation control means 25 replaces the precooling set temperature TFSET2 recorded in the first recording means with the freezer compartment set temperature TFSET, replaces the precooling upper limit temperature TFH2 with the freezer compartment upper limit temperature TFH, The precooling lower limit temperature TFL2 is replaced with the freezer compartment lower limit temperature TFL, and normal operation control as shown in FIG.
[0085]
The temperature change of the refrigerator compartment and the freezer compartment when the above-described pre-cooling operation is performed and goods are stored in the freezer compartment will be described with reference to FIGS.
[0086]
In S111, the operation control means 15 closes the damper 27, and the control proceeds to S112. In S112, the operation control means 15 compares the freezer temperature with the precooling upper limit temperature TFH2. Since the freezer temperature is higher than the precooling upper limit temperature TFH2, the control proceeds to S113, and the operation control means 15 operates the compressor 4 and the blower fan 9. Next, the process proceeds to S114, but since the freezer temperature is higher than the precooling lower limit temperature TFL2, the process proceeds to S115. If it is determined in S115 that the blower fan operation time TIME (F) does not exceed the predetermined time TS (F), the control proceeds to S116.
[0087]
While the pre-cooling operation control means 25 has not received the pre-cool release signal, the control is repeated between S114 and S116, and cooling of the freezer compartment is continued. When storage is started when the freezer temperature has not reached the precooling lower limit temperature TFL2, a precool release signal reaches the precooling operation control means 25, the precooling operation is terminated, and the normal operation is resumed.
[0088]
When the pre-cooling operation control is performed as described above, the temperature change of 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 by the precooling operation as compared with the normal operation, the temperature change when the precooling operation indicated by the dotted line in FIG. The freezer temperature is kept low, and it is possible to suppress the melting of articles and ice that have already been stored and frozen, and the deterioration of the materials of the articles accompanying the melting.
[0089]
In the second embodiment, a large amount of articles are stored in the refrigerator compartment in order to lower the freezer compartment temperature from the preset internal temperature by transmitting information for storing the articles in the refrigerator compartment to the refrigerator. Even if all or most of the cooling air is supplied to the refrigerator compartment, the temperature inside the refrigerator compartment can be quickly lowered, and the temperature inside the compartment inside the refrigerator compartment is lowered to a lower quality. There is no rise.
[0090]
In the first and second embodiments described above, the signal generated when the precool release button 44 is pressed is used as the precool release signal. However, the door switch of the refrigerator compartment or the freezer compartment transmits a door open signal for a predetermined time or more. When continuing, this door opening signal may be regarded as a precool release signal. Moreover, after the opening signal of the refrigerator compartment door switch 42 is transmitted, when the temperature detected by the refrigerator compartment temperature sensor 30 rises to a predetermined value or more, the detected temperature rise may be regarded as a precool release signal. Furthermore, after the opening signal of the freezer compartment door switch 43 is transmitted, when the temperature detected by the refrigerating compartment temperature sensor 31 rises to a predetermined value or more, the detected temperature rise may be regarded as a precooling release signal.
[0091]
Further, a CCD camera, an infrared sensor, or the like may be provided in the cabinet, and the storage of the article may be directly detected, and the increase information of the article stored in the cabinet may be regarded as the precool release signal. Further, a label that can be detected by a predetermined sensor may be attached to the stored article, and the storage of the article in the warehouse may be detected by the predetermined sensor, and the detection information may be regarded as a precool release signal. In addition, a timer may be provided in the refrigerator, and a precool release signal may be transmitted from the timer when a predetermined time has elapsed since the start of the precool operation.
[0092]
However, when using the door opening signal or the internal temperature instead of the pre-cool release button 44, the person staying at home is not allowed to wait until the purchaser returns home after the article information is transmitted from the store. Is opened for a certain period of time or more, and the internal temperature rises, there is a risk that the operation of setting the internal temperature to be preset before the required internal temperature is reached.
[0093]
The third embodiment according to the present invention corresponds to the above-mentioned problem, and is provided with a pre-cooling operation holding switch installed in the refrigerator as operation holding means. The pre-cooling operation hold switch transmits a hold signal to the pre-cooling operation control means 25 when pressed. The pre-cooling operation control means 25 that has received this signal continues to maintain the pre-cooling operation until it receives a signal from the pre-cooling operation hold switch again.
[0094]
That is, in a refrigerator configured such that a door open signal from the door switch of the refrigerator compartment or freezer compartment is regarded as a precool release signal, the door of the refrigerator compartment or freezer compartment is checked in order to check the contents stored in the refrigerator during the precool operation. If the is kept open for a certain period of time, there is a problem that the pre-cooling operation ends. However, if the above-mentioned pre-cooling operation hold switch is provided in the refrigerator and the pre-cooling operation hold switch is pushed before opening the refrigerator or freezer door, the pre-cooling operation can be performed even if the door is opened before storing the goods during the pre-cooling operation. You don't have to end
[0095]
In said 1st-3rd Example, the goods information with respect to a refrigerator may be transmitted through the process shown in FIG. In FIG. 2, 208 is a mobile phone held by the user, and 209 is a display of the mobile phone.
[0096]
After the transaction at the store is completed, the user of the refrigerator displays a pre-cooling operation start screen by operating a predetermined key of the mobile phone, designates the telephone 201 at home, and presses the call button. By this operation, the article information to the freezer compartment is transmitted to the telephone 201 via the public line 204. When the information reception on the telephone 201 side is completed, the telephone 201 disconnects the call. The telephone 201 transmits article information to the freezer compartment from the telephone-side indoor communication device 202 to the refrigerator-side indoor communication device 18 via the indoor communication line 203.
[0097]
In the refrigerator 1, after receiving the article information to the freezer compartment from the refrigerator-side indoor communication device 18, the precooling operation control means 25 and the operation are performed so that the freezer compartment has a temperature lower than the preset freezer compartment set temperature. A pre-cooling operation by the control means 15 is performed. When the pre-cooling release signal reaches the pre-cooling operation control means 25 after the start of the pre-cooling operation, the pre-cooling operation is terminated as if the article storage into the freezer is started, and the freezer temperature reaches a preset freezer temperature. Switch to normal operation.
[0098]
Moreover, in said Example 1-3, although the article form to the freezer compartment or the refrigerator compartment recorded the brand name, the packaging form corresponding to a brand name, and the weight corresponding to a brand name, it is the 3rd record. The means 20 directly associates the product name with the packaging form-corresponding numerical value Cp, and defines Cp as the product name-corresponding numerical value, so that the contents recorded in the article storage information in the freezer compartment or the refrigerator compartment are stored in the product name and the product name. It is also possible to have a corresponding weight.
[0099]
【The invention's effect】
According to the present invention, the packaging form information or weight information of the article is transmitted to the refrigerator, the freezer is cooled down from the normal set temperature, and then returned to the normal set temperature. Temperature rise can be suppressed.
