Description

Embodiments of the present invention relate to refrigerators.

In recent years, as the number of double-income households has increased, the number of meals that are eaten at home by purchasing ready-made foods cooked outside the home and taking them home or by delivering them, that is, so-called ready-to-eat meals, is increasing. Although such foods for ready-to-eat meals are consumed within a relatively short period of time after purchase, they may be stored for about half a day to several days in some cases. Therefore, there is an increasing need to preserve such cooked foods deliciously.

Here, the reason why the taste of cooked rice or bread deteriorates with the passage of time is that the starch contained in the rice or bread is pregelatinized immediately after cooking but becomes β with the passage of time. be. The β-formation of starch is most likely to proceed when the surface of the starch is in a liquid phase, that is, at about 2 ° C. to 4 ° C.

In a conventional refrigerator, the refrigerating room is maintained in a refrigerating temperature range of 3 ° C. to 5 ° C. or a so-called chilled temperature range of 0 ° C. to 3 ° C. so that fresh foods and the like can be stored for a longer period of time. Therefore, when the cooked food is stored in the conventional refrigerator, the beta conversion of starch is promoted, and the taste is rather impaired. Therefore, the conventional refrigerator is not suitable for storing cooked foods.

In addition, the communication unit 42 can receive various instructions from the information terminal 93, the server 94, and the like.

As shown in FIG. 3, the refrigerator 10 includes a normal refrigerating compartment temperature sensor 43, a high temperature switching compartment temperature sensor 44, a chilled compartment temperature sensor 45, and a storage detection unit 46.

The chilled compartment temperature sensor 45 has a function of measuring the temperature inside the chilled compartment 25.

The storage detection unit 46 has a function of detecting that a stored object is stored in the high temperature switching section 24. In this case, the storage detection unit 46 measures the function of detecting the opening / closing of the shutter 36, the function of detecting the presence or passage of an object in the high temperature switching section 24, or the weight of the object stored in the high temperature switching section 24. It can be composed of a mechanical, optical, or electrical sensor that has the function of performing. Further, the storage detection unit 46 can be configured by, for example, a button provided on the operation panel 41 or a specific operation. Further, the storage detection unit 46 can be configured to detect the presence of an object in the high temperature switching section 24 by using, for example, a camera or a sound wave. The normal refrigerating compartment temperature sensor 43, the high temperature switching compartment temperature sensor 44, the chilled compartment temperature sensor 45, and the storage detection unit 46 are each electrically connected to the control device 40, and the detection result of each sensor is transmitted to the control device 40. Send.

The control device 40 controls the switching valve of the refrigeration cycle (not shown), and also controls the compressor 17 and the blower 19 to control the supply of cold air to the storage chambers 11, 12, 13, 14, and 15. In the case of the present embodiment, the control device 40 alternately cools the storage chambers 11 and 12 in the refrigerating temperature zone and cools the storage chambers 13, 14 and 15 in the freezing temperature zone. For example, the control device 40 alternately cools the storage chambers 11 and 12 in the refrigerating temperature zone for 60 minutes and the storage chambers 13, 14 and 15 in the freezing temperature zone for 40 minutes.

The refrigerator 10 has a normal operation mode and a high temperature switching mode for the high temperature switching section 24 as an operation mode for adjusting the temperature in the refrigerating chamber 11, and a normal chilled mode and a low temperature for the chilled section 25. It has a chilled mode. That is, as shown in FIG. 4, the control device 40 can switch between the normal refrigeration mode and the high temperature switching mode for the high temperature switching section 24. Further, the control device 40 can switch between the normal chilled mode and the low temperature chilled mode for the chilled compartment 25. Each mode can be switched by, for example, the user operating the operation panel 41. The control device 40 maintains the normal refrigerating section 23 in a refrigerating temperature range of, for example, 3 ° C. to 5 ° C. regardless of the modes set in the high temperature switching section 24 and the chilled section 25.

The normal refrigeration mode is a mode in which the temperature in the high temperature switching section 24 is maintained in a normal refrigeration temperature range, for example, a temperature range of 3 ° C. to 5 ° C. The high temperature switching mode is a mode for maintaining the temperature in the high temperature switching section 24 in a high temperature zone higher than the refrigerating temperature zone. In this case, the high temperature zone is, for example, a temperature zone in which β conversion of starch can be suppressed and deterioration of the taste of the cooked food can be suppressed, specifically, in the range of, for example, 5 ° C to 15 ° C. Can be set to the temperature range of. Therefore, the high temperature switching section 24 can be referred to as a ready-to-eat room or a ready-to-eat section for storing so-called prepared meals.

Further, the normal chilled mode is a mode in which the temperature in the chilled compartment 25 is maintained in a normal chilled temperature range, for example, a temperature range of 1 ° C. to 3 ° C. The low temperature chilled mode is a mode for maintaining the temperature in the chilled compartment 25 in a low temperature chilled temperature zone lower than the normal chilled temperature zone. In this case, the low temperature chilled temperature zone is set to the temperature immediately before the contained material freezes, for example, about 0 ° C. to 1 ° C.

The control device 40 can adjust the temperature zones of the compartments 23, 24, and 25 by adjusting the temperature and the supply amount of the cold air for the compartments 23, 24, and 25. In the case of the present embodiment, the control device 40 adjusts the temperature and the amount of cold air supplied to the compartments 23, 24, and 25 by, for example, adjusting the rotation speed of the compressor 17 and the amount of air blown by the blower 19. Execute each mode.

Specifically, the control device 40 can perform normal control, high temperature control, and low temperature control. In the normal control, cold air is supplied to the normal refrigerating section 23, the high temperature switching section 24, and the chilled section 25 to maintain the normal refrigerating section 23 and the high temperature switching section 24 in the refrigerating temperature range of 3 ° C. to 5 ° C. The control is to maintain the chilled compartment 25 in the normal chilled temperature range of 1 ° C. to 3 ° C. In the present embodiment, the rotation speed of the compressor 17 and the amount of air blown by the blower 19 are based on this normal control. In this case, in FIG. 5, both the rotation speed of the compressor 17 and the amount of air blown by the blower 19 in this normal control are represented as “medium”. In this normal control, the control device 40 controls the rotation speed of the compressor 17 so that the temperature of the refrigerating cooler 16 is, for example, about 1 ° C.

The high temperature control reduces or stops the supply of cold air to the high temperature switching section 24 as compared with the execution of the normal control, or supplies air having a temperature higher than the cold air supplied by the normal control to the high temperature switching section 24. It is a control that maintains a high temperature range of ° C to 15 ° C. In the case of the present embodiment, the control device 40 stops the rotation speed of the compressor 17 and increases the amount of air blown by the blower 19 as compared with the case of the normal control by executing the high temperature control.

When the compressor 17 is stopped and the supply of the refrigerant to the refrigerating cooler 16 is stopped due to the execution of the high temperature control, the temperature of the refrigerating cooler 16 approaches the temperature of the outside air, and rises to, for example, about 10 ° C to 20 ° C. .. Then, due to the increase in the amount of air blown by the blower 19, most of the warm air around the refrigerating cooler 16 is carried to the upper part of the duct 18 and blown out from the upper outlet 182 into the high temperature switching section 24. As a result, the temperature in the high temperature switching section 24 is maintained in the high temperature zone.

On the other hand, the cold air that existed in the high temperature switching section 24 before the high temperature control was executed is pushed out to the normal refrigerating section 23, for example, through the gap between the shutter 36 and the shelf board 31 by the blower of the blower 19 increased by the high temperature control. .. Then, the cold air flowing out from the high temperature switching section 24 is then lowered by the weight of the cold air. As a result, the normal refrigerating section 23 and the chilled section 25 provided below the high temperature switching section 24 are cooled for a certain period of time even after the high temperature control is executed and the compressor 17 is stopped.

The low temperature control increases the supply of cold air to the chilled compartment 25 as compared with the execution of the normal control, or supplies the chilled compartment 25 with cold air lower than the cold air supplied by the normal control, thereby causing the chilled compartment 25 to have a normal chilled temperature. It is a control to maintain a low temperature chilled temperature zone of, for example, 0 ° C. to 1 ° C., which is lower than the band. In the case of the present embodiment, the control device 40 increases the rotation speed of the compressor 17 and reduces or stops the amount of air blown by the blower 19 by executing the low temperature control, as compared with the case of the normal control.

In the low temperature control, the control device 40 increases the rotation speed of the compressor 17 so that the temperature of the refrigerating cooler 16 becomes, for example, about -1 ° C. Then, when the amount of air blown by the blower 19 is reduced or the blowing is stopped, the cold air generated by the refrigerating cooler 16 stays below the duct 18 without rising due to the weight of the cold air. As a result, while suppressing the supply of excessive cold air to the normal refrigerating section 23 and the high temperature switching section 24 provided above the chilled section 25, it is easy to be supplied to the chilled section 25 provided at the lowermost part in the refrigerating chamber 11. Become. By executing the low temperature control in this way, the chilled section 25 can be maintained in the low temperature chilled temperature zone even lower than the normal chilled mode while suppressing excessive cooling of the normal refrigerating section 23 and the high temperature switching section 24.

As shown in FIG. 5, the control device 40 described above according to the selected state of the normal refrigerating mode or the high temperature switching mode for the high temperature switching section 24 and the selected state of the normal chilled mode or the low temperature chilled mode for the chilled section 25. A combination of control, high temperature control, and low temperature control is performed.

Specific control contents in each mode will be described with reference to FIGS. 6 to 9. In FIGS. 6 to 9, the horizontal axis represents time. Further, in FIGS. 6 to 9, the vertical axis indicates the ability to change the temperature in each of the compartments 23, 24, and 25 to the target temperature zone in each control, and the farther away from the horizontal axis, the greater the ability. It means getting higher.

As shown in FIG. 5, when neither the high temperature switching mode nor the low temperature chilled mode is executed, that is, the normal refrigerating mode is selected for the high temperature switching section 24, and the normal chilled mode is set for the chilled section 25. When selected, the control device 40 continuously executes only normal control for a certain period of time, as shown in FIG. As a result, the normal refrigerating section 23 and the high temperature switching section 24 are maintained in the refrigerating temperature range of 3 ° C. to 5 ° C., and the chilled section 25 is maintained in the normal chilled temperature range of 1 ° C. to 3 ° C.

Further, when the high temperature switching mode is executed and the low temperature chilled mode is not executed, that is, when the high temperature switching mode is selected for the high temperature switching section 24 and the normal chilled mode is selected for the chilled section 25, As shown in FIG. 7, the control device 40 alternately repeats the normal control and the high temperature control at regular intervals. As a result, the normal refrigerating compartment 23 is maintained in the refrigerating temperature zone of 3 ° C. to 5 ° C., the high temperature switching compartment 24 is maintained in the high temperature zone set in the range of 5 ° C. to 15 ° C., and the chilled compartment 25 is 1 It is maintained in the normal chilled temperature range of ° C to 3 ° C.

Further, when the high temperature switching mode is not executed and the low temperature chilled mode is executed, that is, the normal refrigerating mode is selected for the high temperature switching section 24 and the low temperature chilled mode is selected for the chilled section 25. If so, the control device 40 alternately repeats the normal control and the low temperature control at regular intervals, as shown in FIG. As a result, the normal refrigerating compartment 23 and the high temperature switching compartment 24 are maintained in the refrigerating temperature zone of 3 ° C. to 5 ° C., and the chilled compartment 25 is maintained in the low temperature chilled temperature zone of 0 ° C. to 1 ° C.

Then, when both the high temperature switching mode and the low temperature chilled mode are executed, that is, when the high temperature switching mode is selected for the high temperature switching section 24 and the low temperature chilled mode is selected for the chilled section 25, control is performed. As shown in FIG. 9, the device 40 alternately repeats the high temperature control and the low temperature control at regular intervals. As a result, the normal refrigerating compartment 23 is maintained in the refrigerating temperature zone of 3 ° C. to 5 ° C., the high temperature switching compartment 24 is maintained in the high temperature zone set in the range of 5 ° C. to 15 ° C., and the chilled compartment 25 is 0. It is maintained in the low temperature chilled temperature range of ° C to 1 ° C.

Here, when controlling in the direction of lowering the temperature of each section 23, 24, 25, the control device 40 lowers the temperature of the refrigerating cooler 16 by increasing the rotation speed of the compressor 17, thereby lowering the temperature of each section 23. , 24, 25 lower the temperature of the cold air supplied. On the other hand, when controlling in the direction of raising the temperature of each of the compartments 23, 24, and 25, the control device 40 lowers the temperature of the refrigerating cooler 16 by lowering or stopping the rotation speed of the compressor 17. However, in this case, the temperature rise of the refrigerating cooler 16 depends on the outside air and the like. Therefore, the refrigerator 10 can actively control the control in the direction of lowering the temperature of each of the compartments 23, 24, 25, but is relatively relatively controlled in the direction of lowering the temperature of each of the compartments 23, 24, 25. It tends to be passive control. That is, in general, the refrigerator 10 is relatively good at controlling the cooling of the storage chambers 11, 12, 13, 14, and 15, but is relatively poor at controlling the storage chambers 11 and 12, 13, 14, and 15.

Therefore, when two controls for maintaining each of the compartments 23, 24, and 25 in different temperature zones are repeatedly executed, the control device 40 lengthens the execution period in one cycle of the control having the higher temperature, and increases the temperature. The execution period in one cycle of the control with the lower value is shortened. That is, the control period in the cooling direction, which the refrigerator 10 is good at, is shortened, and the control period in the direction of suppressing cooling or raising the temperature, which the refrigerator 10 is not good at, is secured for a long time. As a result, even when the compartments 23, 24, and 25 are maintained in different temperature zones, the temperatures in the compartments 23, 24, and 25 can be accurately maintained in the set temperature zones.

Specifically, the high temperature switching mode is selected for the high temperature switching section 24 and the normal chilled mode is selected for the chilled section 25, and the high temperature control and the normal control are alternately executed as shown in FIG. In this case, the control device 40 sets the execution period T2 of the high temperature control, which is the control having the higher temperature, from the execution period T1 of the normal control, which is the control having the lower temperature, in one cycle of the high temperature control and the normal control. Also set longer.

Further, when the normal refrigeration mode is selected for the high temperature switching section 24 and the low temperature chilled mode is selected for the chilled section 25, and the normal control and the low temperature control are alternately executed as shown in FIG. The control device 40 sets the execution period T4 of the normal control, which is the control having the higher temperature, longer than the execution period T3 of the low temperature control, which is the control having the lower temperature, in one cycle of the normal control and the low temperature control. do.

Then, when the high temperature switching mode is selected for the high temperature switching section 24 and the low temperature chilled mode is selected for the chilled section 25, and the high temperature control and the low temperature control are alternately executed as shown in FIG. The control device 40 sets the execution period T6 of the high temperature control, which is the control having the higher temperature, longer than the execution period T5 of the low temperature control, which is the control having the lower temperature, in one cycle of the high temperature control and the low temperature control. do. As a result, the temperature of each of the compartments 23, 24, and 25 can be precisely controlled.

Further, in this case, the control device 40 controls the high temperature control in the direction of further raising the temperature of the high temperature switching section 24 and one cycle as compared with the case where the high temperature switching mode is executed without executing the low temperature chilled mode. The execution period T6 of the high temperature control in is set short. In this case, the control device 40 further increases the air volume of the blower 19 as compared with the case where the high temperature switching mode is executed and the normal chilled mode is executed, for example, with the compressor 17 stopped. As a result, the temperature of the high temperature switching section 24 rises when both the high temperature switching mode and the low temperature chilled mode are executed, as compared with the case where the high temperature switching mode is executed without executing the low temperature chilled mode. It becomes easier to do.

Further, in this case, as shown in FIGS. 9 and 7, the low temperature chilled mode is not executed during the execution period T6 per cycle of the high temperature control when the high temperature switching mode and the low temperature chilled mode are executed at the same time. It is set shorter than the execution period T2 per cycle of the high temperature control when the high temperature switching mode is executed. Then, as shown in FIGS. 9 and 8, when the high temperature switching mode and the low temperature chilled mode are executed at the same time, the execution period T5 per cycle of the low temperature control is the low temperature chilled mode without the high temperature switching mode being executed. Is set shorter than the execution period T3 per cycle of the high temperature control when is executed.

That is, in the case of the present embodiment, the high temperature switching mode is executed without executing the low temperature chilled mode during the period T5 + T6 of one cycle of the high temperature control and the low temperature control when the high temperature switching mode and the low temperature chilled mode are executed at the same time. That is, it is shorter than the period T1 + T2 of one cycle in the case where the high temperature control and the normal control are alternately executed as shown in FIG. Further, the period T5 + T6 of one cycle of high temperature control and low temperature control when the high temperature switching mode and the low temperature chilled mode are executed at the same time is the case where the low temperature chilled mode is executed without executing the high temperature switching mode, that is, the figure. As shown in 8, the period of one cycle is shorter than the period T3 + T4 when the normal control and the low temperature control are alternately executed. As a result, the internal temperature control between the high temperature switching section 24 and the chilled section 25 can be alternately performed at short intervals, so that the internal temperature between the high temperature switching section 24 and the chilled section 25 can be maintained with high accuracy.

Further, in the present embodiment, the control device 40 can execute management control for managing the storage period of the food stored in the high temperature switching section 24. In this case, for example, the recording area 402 records the management control program. Then, by executing the management control program in the CPU 401, the control device 40 executes the management control.

When the control device 40 executes the management control, in step S11 shown in FIG. 10, based on the detection result of the storage detection unit 46, the control device 40 determines whether or not the food is stored in the high temperature switching section 24. For example, if the storage detection unit 46 detects the opening / closing of the shutter 36, such as an open / close sensor, the control device 40 determines the high temperature switching section 24 when the storage detection unit 46 detects the opening / closing of the shutter 36. It is judged that the food has been stored in.

Further, as shown in FIG. 11, the storage detection unit 46 can be composed of a device for acquiring two-dimensional information such as a camera, a device for acquiring three-dimensional information such as a ToF (Time of Flight) sensor, and the like. .. When the storage detection unit 46 is composed of a camera or a ToF sensor, it is desirable that the storage detection unit 46 covers the entire image area of the high temperature switching section 24 as much as possible. In this case, the control device 40 performs image processing on the image or video taken by the storage detection unit 46, and based on the result of the image processing, the food is stored in the high temperature switching section 24 and the food is delivered from the high temperature switching section 24. Determine that it has been taken out.

Further, the storage detection unit 46 can be configured to detect the presence of an object by reflecting or blocking light or a laser, such as a photoelectric sensor or a laser sensor. In this case, the storage detection unit 46 may be provided on the ceiling portion 113 and arranged so that the optical axis faces in the vertical direction, or may be provided on the left and right wall surfaces and arranged so that the optical axis faces in the left and right horizontal direction. .. In this case, when the light or laser output from the storage detection unit 46 changes from an unreflected or unobstructed state to a reflected or blocked state, the control device 40 puts food in the high temperature switching section 24. Is judged to have been stored. Further, the control device 40 changes from a state in which the light or laser output from the storage detection unit 46 is reflected or blocked to a state in which it is not reflected or blocked, and the high temperature switching section 24 It is judged that food etc. was taken out from.

In this case, at least one storage detection unit 46 may be provided, but for example, as shown in FIG. 12, a plurality of storage detection units 46 may be arranged along the depth direction of the high temperature switching section 24. According to this, the blind spot of the storage detection unit 46 can be reduced, and the control device 40 can detect the loading and unloading of food and the like in a wide range of the high temperature switching section 24.

Further, the storage detection unit 46 may be a weight scale as shown in FIG. 13, for example. In this case, the control device 40 determines that the food is stored in the high temperature switching section 24 when the weight measured by the storage detection unit 46 increases. Further, the control device 40 determines that the food has been taken out from the high temperature switching section 24 when the weight measured by the storage detection unit 46 is reduced.

When the storage of food in the high temperature switching section 24 is not detected (step S11), the control device 40 repeats step S11. Then, when the storage of food in the high temperature switching section 24 is detected (YES in step S11), the control device 40 shifts the process to step S12. The control device 40 executes the storage notification process in step S12. The storage notification process is a process of notifying the user that food has been stored in the high temperature switching section 24. By executing the storage notification process, the control device 40, for example, emits or displays a sound from the operation panel 41 to notify the user that the food has been stored in the high temperature switching section 24.

Next, the control device 40 shifts the process to step S13, and determines whether or not a predetermined time has elapsed after detecting the storage of food in the high temperature switching section 24. The predetermined time can be arbitrarily set by the user, for example, according to the food, and is, for example, a period of several hours to several days.

If a predetermined time has not elapsed since the storage of food in the high temperature switching section 24 was detected (NO in step S13), the control device 40 repeats step S13 until the predetermined period elapses. Then, when a predetermined time elapses after the storage of food in the high temperature switching section 24 is detected (YES in step S13), the control device 40 shifts the process to step S14 and executes the attention notification process.

The caution notification process is a process of notifying the user that a predetermined time has elapsed without taking out the food from the high temperature switching section 24 after the food is stored in the high temperature switching section 24. By executing the caution notification process, the control device 40, for example, emits or displays a sound from the operation panel 41 to notify the user that a predetermined period has elapsed since the food was stored in the high temperature switching section 24. do.

In this case, the storage notification process in step S12 and the caution notification process in step S14 are performed after, for example, the user's information terminal 93 has stored food in the high temperature switching section 24 via the communication unit 42, and the food has been stored. It may be displayed that the predetermined period has passed. In this case, the notification mode may be as follows. That is, for example, the calendar may be displayed on the user's information terminal 93, and the date when the food is put in the calendar and the date when the food should be taken out may be displayed. Further, the date when the food is put in and the date when the food should be taken out may be displayed side by side in chronological order on, for example, the user's information terminal 93.

According to the embodiment described above, the refrigerator includes a refrigerating chamber 11 which is a storage chamber that can be maintained in the refrigerating temperature zone, and a control device 40 that controls the supply of cold air to the refrigerating chamber 11. The refrigerating chamber 11 has a high temperature switching section 24. The high temperature switching section 24 is provided in a part or all of the refrigerating chamber 11, and is configured to be switchable between a refrigerating temperature zone and a high temperature zone higher than the refrigerating temperature zone. Then, the control device 40 can switch between normal control and high temperature control for the high temperature switching section 24. The normal control is a control in which cold air is supplied to the high temperature switching section 24 to maintain the high temperature switching section 24 in the refrigerating temperature zone. The high temperature control reduces or stops the supply of cold air to the high temperature switching section 24 as compared with the execution of the normal control, or supplies air having a temperature higher than that of the cold air supplied by the normal control to raise the high temperature switching section 24. It is a control that maintains the temperature range.

According to this, the refrigerator 10 can switch the high temperature switching section 24 into a section in the refrigerating temperature zone and a section in the high temperature zone. As a result, the high temperature switching section 24 can be normally used as the refrigerating temperature zone section, and the high temperature switching section 24 can be switched to the high temperature zone section as needed. Then, by storing the cooked food such as rice and bread in the high temperature switching section 24 switched to the high temperature zone, the user can suppress the deterioration of the taste of the food and store it in a delicious state. ..

Further, the high temperature switching section 24 is provided in a part of the refrigerating chamber 11. The refrigerating room 11 usually further has a refrigerating section 23. The normal refrigerating section 23 is a section provided in the refrigerating chamber 11 different from the high temperature switching section and maintained in the refrigerating temperature zone. Then, the control device 40 can be executed by switching between the normal refrigeration mode and the high temperature switching mode. The normal refrigerating mode is a mode in which the high temperature switching section 24 and the normal refrigerating section 23 are maintained in the refrigerating temperature zone by executing the normal control. The high temperature switching mode is a mode in which the high temperature switching section 24 is maintained in the high temperature zone and the normal refrigerating section 23 is maintained in the refrigerating temperature zone by executing the high temperature control.

According to this, when the normal refrigerating mode is executed, the normal refrigerating section 23 and the high temperature switching section 24 can be used as a storage section in the refrigerating temperature zone. Further, when the high temperature switching mode is executed, the high temperature switching section 24 can be used as the storage section in the high temperature zone while the normal refrigerating section 23 is used as the storage section in the refrigerating temperature zone. Therefore, when the high temperature switching mode is executed, the refrigerated product suitable for storage in the refrigerated temperature zone and, for example, cooked food suitable for storage in the high temperature zone are simultaneously stored in the refrigerated chamber 11. can do. As a result, the convenience of the user can be improved.

Further, the refrigerator compartment 11 further has a chilled compartment 25. The chilled section 25 is provided in a section different from the high temperature switching section 24 and the normal refrigerating section 23 in the refrigerating chamber 11, and is a section maintained in a chilled temperature zone lower than the refrigerating temperature zone. Further, the normal control includes a control for maintaining the chilled compartment 25 at a normal chilled temperature by supplying cold air to the chilled compartment 25. Then, the control device 40 can further execute the low temperature control and further execute the low temperature chilled mode.

The low temperature control increases the supply of cold air to the chilled compartment 25 as compared with the execution of the normal control, or supplies cold air lower than the cold air supplied by the normal control to make the chilled compartment 25 more than the normal chilled temperature zone. It is a control that maintains a lower low temperature chilled temperature range. The low temperature chilled mode is a mode in which the chilled compartment 25 is maintained in the low temperature chilled temperature zone and the normal refrigerated compartment 23 is maintained in the refrigerated temperature zone by executing the low temperature control.

According to this, the refrigerator 10 has a chilled compartment 25 in the refrigerating chamber 11 which is maintained in a chilled temperature zone lower than the refrigerating temperature zone. Then, the refrigerator 10 can maintain the chilled compartment 25 in a low temperature chilled temperature zone lower than the normal chilled temperature zone by executing the low temperature chilled mode. Therefore, according to the present embodiment, since the refrigerating chamber 11 is provided with a large number of temperature zone sections, it can be stored in a temperature zone suitable for storage.

When the high temperature switching mode is executed without executing the low temperature chilled mode, the control device 40 executes the high temperature control without executing the low temperature control. According to this, when only the high temperature switching mode is executed, the control device 40 executes the high temperature control without executing the low temperature control, so that the high temperature switching section 24 is cooled by the low temperature control. You can prevent that. As a result, the high temperature switching section 24 can be maintained in the high temperature zone with high accuracy.

When the low temperature chilled mode is executed without executing the high temperature switching mode, the control device 40 executes the low temperature control without executing the high temperature control. According to this, when only the low temperature chilled mode is executed, the control device 40 executes the low temperature control without executing the high temperature control, so that the chilled section 25 is warmed by the high temperature control. Can be prevented. As a result, the inside of the chilled compartment 25 can be maintained in the low temperature chilled temperature zone with high accuracy.

Further, when both the high temperature switching mode and the low temperature chilled mode are executed, the control device 40 alternately executes the high temperature control and the low temperature control at a predetermined cycle. According to this, the normal refrigerating section 23, the high temperature switching section 24, and the chilled section 25 are different from each other without partitioning the normal refrigerating section 23, the high temperature switching section 24, and the chilled section 25 with a member having a heat insulating property. Can be maintained in the temperature range. Thereby, the normal refrigerating section 23, the high temperature switching section 24, and the chilled section 25 can be realized with a simple configuration and at low cost.

Here, as described above, the refrigerator 10 is better at low temperature control than high temperature control due to the nature of the refrigeration cycle. That is, when comparing the high temperature control and the low temperature control, the low temperature control converges to the target temperature in a shorter period of time than the high temperature control. Therefore, when both the high temperature switching mode and the low temperature chilled mode are executed, the control device 40 alternately executes the high temperature control and the low temperature control in different predetermined cycles, and the high temperature control in one cycle. Make the execution period longer than the low temperature control.

According to this, when both the high temperature switching mode and the low temperature chilled mode are executed, the execution period per cycle of the high temperature control, which the refrigerator 10 is not good at, is longer than the execution period of the low temperature control. By doing so, the temperature control of the high temperature switching section 24 by the high temperature control can be performed more precisely.

Further, when both the high temperature switching mode and the low temperature chilled mode are executed, the control device 40 alternately executes the high temperature control and the low temperature control at different predetermined cycles, and executes the high temperature switching mode. Compared with the case where the low temperature chilled mode is executed without the chilled mode, the low temperature control is controlled in the direction of further lowering the temperature of the chilled section 25, and the execution period of the low temperature control in one cycle is shorter than that of the high temperature control. According to this, the low temperature control and the high temperature control can be alternately and repeatedly executed in a short period of time. Therefore, when the high temperature switching section 24 is maintained in the high temperature zone and the chilled section 25 is maintained at the low temperature chilled temperature, both can perform temperature control with high accuracy.

Further, when both the high temperature switching mode and the low temperature chilled mode are executed, the control device 40 alternately executes the high temperature control and the low temperature control at different predetermined cycles, and executes the low temperature chilled mode. Compared with the case where the high temperature switching mode is executed without the high temperature switching mode, the high temperature control is controlled in the direction of further raising the temperature of the high temperature switching section 24, and the execution period of the high temperature control in one cycle is shorter than that of the low temperature control. Also with this, the low temperature control and the high temperature control can be alternately and repeatedly executed in a short period of time. Therefore, when the high temperature switching section 24 is maintained in the high temperature zone and the chilled section 25 is maintained at the low temperature chilled temperature, both can perform temperature control with high accuracy.

Further, the refrigerator 10 is further provided with a blower 19 for supplying cold air into the refrigerator compartment 11. Then, the control device 40 can control the drive of the blower 19, and when the high temperature switching mode is executed, the control device 40 increases the amount of air blown by the blower 19 as compared with the case where the high temperature switching mode is not executed. To execute. In this case, it is preferable that the number of revolutions of the compressor 17 is reduced or stopped as compared with the normal refrigerating mode. According to this, for example, air warmer than the cold air supplied in the normal refrigerating mode can be supplied to the high temperature switching section 24 without using a heater or the like for heating the high temperature switching section 24, so that the high temperature switching section 24 can be supplied. The inside can be easily maintained in a high temperature zone.

Further, the control device 40 executes control to reduce the amount of air blown by the blower 19 when the low temperature chilled mode is executed as compared with the case where the low temperature chilled mode is not executed. In this case, it is preferable that the number of revolutions of the compressor 17 is increased as compared with the normal refrigerating mode. According to this, since cold air that is colder than the cold air that is normally supplied in the chilled mode can be supplied to the chilled compartment 25, the inside of the chilled compartment 25 can be easily maintained in the low temperature chilled temperature zone.

The position of the high temperature switching section 24 is not limited to the configuration of the above-described embodiment. For example, the high temperature switching section 24 may be provided at the middle position of the refrigerating chamber 11, that is, at the position of the normal refrigerating section 23 of the above embodiment. Further, the high temperature switching section 24 may be provided at the lower position of the refrigerating chamber 11, that is, at the position of the chilled section 25 of the above embodiment.
