Order 'Quan · Ministry of Economics Central A7 _B7_ printed by the Staff Consumer Cooperative of the Bureau of Standards V. Description of invention (7) Action flow chart. The control device 11 first clears the door opening flag and the forced operation flag (step S1), and then clears the accumulation timer (step 2). In the normal cooling operation, if the door is opened according to the door switch 8 ~ 10, the door opening flag is set (step S3), and if the forced operation button 1 2 is pressed to perform the forced operation, the forced operation flag is set Mark. During the period when the compressor 23 is turned on, the accumulation timer is driven (steps S7, S8), and during the period when the compressor 23 is off, the accumulation timer is stopped (steps S7, S9), and the cumulative operation time of the compressor 23 is calculated. When the accumulated value of the accumulation timer becomes 10 hours (step S10), it is temporarily determined to be the defrosting start sequence, but it is determined whether the defrosting start is not performed and the first extension operation delayed by a certain time is performed due to the following control . In the normal cooling control, if the reset state of the door open flag, that is, the closed state of the doors 5 to 7 continues to exist, the amount of frost attached to the cooler 15 is small, even if the defrosting operation is delayed. However, if the doors 5 to 7 are opened, a large amount of air intrudes into the refrigerator so that a large amount of frost adheres to the cooler 15. At this time, if the defrosting operation is postponed, the effect will occur. Similarly, when the forced operation is performed, the heat exchange amount of the cooler 15 increases and the frost attachment speed increases, so if the defrosting operation is postponed, the effect will occur. The control device 11 determines whether the door opening flag or the forced operation flag is set after the accumulated time reaches 10 hours (step S11).

Description of the invention (8) Within a fixed temperature range (for example, 20 ° C ~ 30 ° C) (step S12). At this time, if the atmospheric temperature is estimated to be outside a certain temperature range, the flag is cleared and the defrosting operation is performed (steps S23, S24) (Figure 3). In this way, when the atmospheric temperature is lower than a certain temperature range, the operation rate of the refrigerator is reduced and defrosting cannot be performed for a long time, so if the food containing a large amount of moisture is stored in the refrigerator, the frost attached to the cooler 15 solidifies and becomes unusable Easy to dissolve in the form of ice, cooling performance is reduced and can not delay defrosting operation. If the atmospheric temperature is higher than a certain temperature range, the operating rate of the compressor 23 increases, the heat exchange amount (cooling amount) of the cooler 15 increases, and frost easily adheres to the cooler 15, so the defrost cannot be delayed. Running. The estimation of the atmospheric temperature can be calculated based on the relationship between the temperature of the storage space (closed space) detected by the temperature sensor (not shown) provided in the control device 11 and the atmospheric temperature. The temperature of the storage space is relatively changed by the influence of the atmospheric temperature, so the atmospheric temperature can be estimated based on the temperature of the storage space. Printed by the Staff Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) During the normal cooling operation, if the closed state of the doors 5 ~ 7 and the non-operation state of the forced operation button 12 continue to exist and When it is estimated that the atmospheric temperature is within a certain temperature range, the control device 11 judges that the defrosting operation is not necessary to clear the counter, and starts the real time timer (steps S 1 3 and S 1 4), and continues for a certain time (for example, 100 Points) for the cooling operation, whereby the first extension operation can be performed (step S19). During the first extension operation, the control device 11 sets the door opening flag when opening the doors 5 to 7 (steps S15, S16), and sets the forced operation flag when pressing the forced operation button 12 (steps S 17, 7, S 1 8). When the first extension action ends, it becomes the defrosting start sequence, so the paper size of the control is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm). 11 Printed by the Ministry of Economic Affairs, Central Standard Falcon Bureau Beigong Consumer Cooperative A7 B7 5. 3. Description of the invention (9) The device 1 1 determines whether any of the door opening flag or the forced operation flag has been set (step S20), and if the flag has been set, the defrosting operation is performed (step S2 4 ). When the first extension operation ends, the atmospheric temperature is not estimated. The reason is that under normal home use environment, the room temperature cannot change by 1 o ° c abruptly. Therefore, it is sufficient to estimate the air temperature from the first defrost start timing. 'At the time when the control device 11 starts the defrost start sequence after the end of the first extension operation' If the defrost condition is not established, the second extension operation that delays the start of the defrost again for a certain time (100 minutes) is performed, and At the defrosting start timing after the end of the second extension operation, if the defrost condition is not satisfied, the second extension operation is repeatedly performed (step S22). At this time, if the control device 11 judges that the defrosting operation must be performed according to the door opening flag and the forced operation flag at the defrosting start timing after the end of the second extension operation (step S 2 1), the defrosting operation is performed (Figure 4). The control device -11 repeats the second extension operation to reach the count value, that is, after performing the predetermined number of second extension operations (steps S 2 1, S 2 2), it determines that the defrost condition has been established and performs the defrost Run (Figure 5). At this time, the prescribed number of times of the second extension operation can be based on the defrosting operation interval that can maximize the cooling effect and save power under the condition that the doors 5 to 7 are closed and the non-progressive state of the forced operation continues. Calculation. In other words, if the defrosting operation interval is set to, for example, 24 hours, the cumulative operation time of the compressor 23 during the normal cooling operation is 10 hours, and thereafter 3 times (1st extended operation, 2nd extended operation) ) Every 100 minutes of extended action time, this paper can be adapted to the Chinese National Standard (CNS) A4 specifications (210X297 mm)!

When the cumulative operation time of the compressor 23 is converted to a real time, the operation rate of the compressor 2 3 can be calculated according to the operation rate of the compressor 2 3 under the condition that the defrosting start delay of the external air temperature is 20 ° C ~ 3 0 ° C. The real time of 0 hours accumulated running time. In this embodiment, it is judged whether to delay the start of defrosting at the end of the extension operation. The reason is that according to the structure that the doors 5 to 7 are opened during the extended operation or the defrosting operation is immediately performed by the operation of the forced operation button 12, if the doors 5 to 7 are opened to cool and store the food during the extended operation, it is immediately Carry out the defrosting operation. If the defrosting operation is not completed, the food cannot be cooled and stored. Similarly, if the forced operation is desired during the extended operation and the forced operation button 12 is pressed, the defrosting operation is performed immediately and the forced operation cannot be performed. In this embodiment, it is determined whether the flag used in the defrosting start timing after the extended operation ends and the defrosting start timing is cleared when the defrosting operation is performed. The reason is that if the doors 5 to 7 are opened during the defrosting operation to pick and place food, a large amount of moisture-containing air penetrates into the refrigerator, and a large amount of frost may adhere to the cooler 15 during the subsequent cooling operation. Therefore, when opening and closing doors 5 to 7, it must be tested even during defrosting. According to the above structure, when the conditions that do not require the defrosting operation of the cooler 15 to continue to the preset defrosting start timing, the first extension operation that delays the start of the defrosting by a certain time is performed without the need for defrosting. When the condition of the frost operation continues until the defrosting start timing after the end of the extension operation, the second extension operation that performs the extension operation a predetermined number of times is performed. Therefore, the size of this paper is applicable to the Chinese National Standard (CNS) A4 (210 X 297mm): ----- Ίprivate clothing— ((Please read the precautions on the back before filling this page)

Description of invention (11) When the conditions that do not require defrosting operation continue to exist, you can charge a large fee: ¾ Defrosting operation as possible After the delay, the power is saved, and once the conditions that require the defrosting operation occur, the normal cooling operation or the defrosting operation can be performed at the end of the extended operation sequence, so the cooling performance of the cooler 15 can be maintained. Therefore, unlike a conventional device that performs a defrosting operation when a certain time has elapsed since the last defrosting operation or when the cumulative operation time of the compressor becomes a certain value, the defrosting operation can be performed at an appropriate timing, so that energy efficiency can be improved. In addition, unlike the method of estimating the defrost start timing, the control device 11 does not need to have functions such as high-speed calculation and high calculation accuracy, so the control device 11 can be simplified and the cost can be reduced. In this embodiment, the specific value of power saving is 1; for example, in a refrigerator with a capacity of 400 liters, if the defrost interval is set to a real time of 24 hours or more, 2 KW of power can be saved in a month. If the defrost interval is set to more than 7 2 hours in real time, 4 to 5 KW of electricity can be saved in one month. Fig. 6 shows a flow chart of the control device 11 of the second embodiment of the present invention. The second embodiment differs from the first embodiment in that the accumulated operation time of the compressor 23 is used to determine the delay time when the extended operation is performed. When the control device 11 determines that the defrosting operation is not to be performed based on the flag when the defrosting sequence is reached (steps S11, S12), the counter is counted (step S1 3), and if the count value is 1, it is determined that the normal cooling operation is ended According to the estimated defrosting start timing, it is determined whether or not to delay the start of defrosting based on the estimated atmospheric temperature (steps S14, S15).
