Description

Embodiments of the present invention relate to a refrigerator.

In recent years, with the increase in the number of dual-income households, there has been an increase in the number of ready-made meals that are eaten at home by purchasing ready-made food prepared outside the home and taking it home or having it delivered. Although such ready-to-eat foods are consumed within a relatively short period of time after purchase, they may be stored for half a day to several days depending on the case. Therefore, there is a growing need to preserve such cooked foods in a delicious manner.

The reason why the taste of cooked rice and bread deteriorates over time is because the starch contained in rice and bread is already gelatinized immediately after cooking, but becomes beta over time. be. Beta conversion of starch is most likely to occur when the surface of the starch is in a liquid phase, that is, at about 2°C to 4°C.

In conventional refrigerators, the inside of the refrigerator compartment is maintained at a refrigeration 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 can be stored for longer periods of time. Therefore, if cooked food is stored in a conventional refrigerator, the beta conversion of starch will be accelerated, and the taste will be impaired. Therefore, refrigerators with conventional configurations are not suitable for storing cooked foods.

Therefore, a refrigerator having a special high-temperature section that can be switched between a refrigeration temperature zone and a high temperature zone higher than the refrigeration temperature zone in the storage room is being considered.

Here, some foods have different temperature ranges suitable for different parts of the food. For example, for sushi, it is best to store vinegared rice, which contains a lot of starch, within the range of about 10°C to 20°C, while so-called toppings such as raw fish should be stored within the range of about 2°C to 3°C. It is best to keep it. In addition, while cakes and sponges containing a lot of starch are best stored within a range of approximately 10°C to 20°C, fresh cream should be stored within a range of approximately 2°C to 3°C. is optimal.

Therefore, a refrigerator is provided in which a plurality of temperature zones are provided in one compartment and the food can be stored in a temperature zone suitable for each part of the food, thereby improving convenience for the user.

The control device 16 can transmit various information such as the operating status of the refrigerator 10 to an information terminal or a server that is an external device. Additionally, the communication unit can receive various instructions from information terminals, servers, and the like.

The refrigerator 10 has a special compartment A in one or more of the storage compartments 11, 12, 13, 14, and 15. The special compartment A is a compartment in which the temperature within the compartment can be maintained in a temperature range different from the normal temperature range of each storage room having the compartment. The special section A may be provided in a part of each storage room, or may be provided in the entirety of each storage room. When special compartment A is provided in a part of each storage room, special compartment A is physically separated from compartments other than special compartment A in the storage room by a wall that has heat insulation properties or does not have heat insulation properties. It is configured. The wall separating special section A from sections other than special section A only needs to allow the user to recognize special section A as an independent space that is physically separated from sections other than special section A. There is no need to completely cut off the area from areas other than special area A. That is, the special section A does not need to be sealed, and the special section A and sections other than the special section A may be in communication with each other in part.

In this embodiment, the special compartment is provided in a part of the refrigerator compartment 11, which is a storage compartment in the refrigeration temperature range. Although the special section A may be provided anywhere in the refrigerator compartment 11, the chilled room 35 functions as the special section A in this embodiment. The chilled room 35 is physically separated from sections other than the special section A in the storage room 11 by a partition wall 39 that does not have heat insulation properties, a shelf board 34, and a rotating lid (not shown). There is. In this embodiment, the food 100 stored in the special compartment A is housed in a case 351. Although illustration of the case 351 is omitted in FIGS. 5, 6, etc., a slit (not shown) is formed on the back surface of the case 351, and cold air supplied from the air passage 36 can flow into the inside of the case 351. It is possible to flow out from the case 351.

Special compartment A contains multiple areas within it that can be maintained at different temperature zones. For example, the special section A includes a normal region A1 and a weakly cooled region A2. The normal area A1 is an area that is maintained in the normal temperature zone of the storage room 11 having the special section A, in this case the refrigerated temperature zone or the chilled temperature zone. In this embodiment, the normal area A1 is an area maintained in a chilled temperature range. The weakly cooled region A2 is a region maintained in a high temperature range higher than the temperature range of the normal region A1. That is, the weakly cooled area A2 is an area where cooling is suppressed compared to sections other than the special section A and/or the normal area A1. The altitude range can be set, for example, within a range of about 10°C to about 20°C. The temperature zone of the weak cooling area A2 may be always maintained in the high temperature zone, or may be configured to be switched between the normal temperature zone and the high temperature zone by user operation or control of the control device. It's okay.

At least one normal area A1 and one weakly cooled area A2 are included in each special section A. In this embodiment, one special section A includes one normal region A1 and one weakly cooled region A2. In other embodiments, for example, one or more normal areas A1 and weakly cooled areas A2 may be arranged alternately within one special section A.

5 and 6 are diagrams schematically representing the special section A. In the special section A, the normal area A1 and the weakly cooled area A2 may be arranged side by side in the vertical direction, for example, with the virtual boundary line L in between, or may be arranged side by side in the left and right direction. . In this embodiment, the normal area A1 and the weakly cooled area A2 are arranged side by side in the vertical direction. Furthermore, in this embodiment, the weak cooling area A2 is arranged below the normal area A1. As a result, the food 100, such as sushi or cakes, which has a lower part suitable for storage at a relatively high temperature and an upper part suitable for storage at a low temperature, can be stored at a temperature range suitable for each part. Can be done.

In addition, in other embodiments, as shown in FIG. 7, the weak cooling area A2 may be arranged above the normal area A1. Also in this case, the special return port 363a and the special air outlet 364a are both provided in the normal area A1. Moreover, the heating part 54a may be provided on the side surface or the top surface of the weakly cooled area A2. For example, in the example shown in FIG. 7, the heating section 54a is provided below the shelf board 34 that serves as the top surface of the weak cooling area A2. In this case, food 100 having a lower part suitable for storage at low temperatures and an upper part suitable for storage at relatively high temperatures can be stored in a temperature range suitable for each part.

In this embodiment, the volume ratio of the normal region A1 and the weakly cooled region A2 may be approximately 1:1, or one may be larger than the other. In this embodiment, the volume ratio of the normal area A1 and the weakly cooled area A2 is set to approximately 1:1. That is, the boundary line L between the normal area A1 and the weakly cooled area A2 is located near the midpoint of the vertical height dimension of the special section A.

The normal area A1 and the weakly cooled area A2 are in communication with each other. That is, food can be stored across the boundary line L between the normal area A1 and the weakly cooled area A2. Here, in FIGS. 5 and 6, no physical barrier is provided between the normal area A1 and the weakly cooled area A2, but the invention is not limited to this. For example, as shown in FIGS. 8 and 9, a removable partition member 352 is attached between the normal area A1 and the weak cooling area A2, and separate foods are stored in the normal area A1 and the weak cooling area A2. You may do so. The partition member 352 is made of a plate-like material having low heat insulation properties, such as a resin member, and physically separates the normal area A1 and the weakly cooled area A2. The partition member 352 does not need to be completely cut off, as long as the normal area A1 and weakly cooled area A2 can be used as separate food storage spaces with the partition member 352 attached to the special section A. That is, in a state where the partition member 352 is attached to the special section A, the normal area A1 and the weakly cooled area A2 may partially communicate with each other. Although the case 351 is not shown in FIGS. 8 and 9, the partition member 352 may be detachably attached to the case 351.

The air passage 36 has one or more special return ports 363, in this case one special return port 363, and one or more special air outlets 364, in this case two. The special return port 363 and the special air outlet 364 are openings that directly or indirectly communicate the special section A and the air passage 36, and allow cool air to enter and exit the special section A. Both the special return port 363 and the special air outlet 364 are formed within the normal area A1. In other words, since both the special outlet 364 and the special return outlet are provided closer to the normal area A1 than the boundary line L, the cold air flowing through the air path 36 is directed from the special outlet 364 toward the normal area A1. The air flows into the air, circulates mainly within the normal area A1, and returns to the air passage 36 through the special return port 363.

In this embodiment, the special return port 363 and the special air outlet 364 are formed on the back surface of the special section A. The downstream side of the special return port 363 is connected to the upstream side of the refrigerating cooler 41 in the air path 36 by an auxiliary air path 365 .

The distance between the special return port 363 and the weak cooling area A2 is set longer than the distance between the special air outlet 364 and the weak cooling area A2. In other words, the special return port 363 is arranged at a position farther from the weak cooling area A2 than the special air outlet 364 is. Therefore, the cold air that has flowed into the normal area A1 from the special air outlet 364 tends to flow in a direction away from the weakly cooled area A2. Thereby, it is possible to prevent the weakly cooled region A2 from being cooled more than necessary. In the present embodiment, the weak cooling area A2 is located below the normal area A1, so the special return port 363 is formed above the special air outlet 364.

The refrigerator 10 includes a first temperature detection section 51, a second temperature detection section 52, and a third temperature detection section 53, as shown in FIG. 4 and the like. The first temperature detection unit 51 detects the temperature of the air within the normal area A1. The second temperature detection unit 52 detects the temperature of the air within the weakly cooled area A2. The first temperature detection section 51 and the second temperature detection section 52 are, for example, thermistors, and can be installed on the wall, top, or bottom of the respective areas A1 and A2. The third temperature detection unit 53 is an infrared sensor capable of detecting the temperature or surface temperature of the food stored in the special section A, for example, the surface temperature of the food.

It is preferable that the third temperature detection unit 53 detects both the temperature of the food in the normal area A1 and the temperature of the food in the weak cooling area A2. For example, a third temperature detection section 53 that measures the temperature of the food in the normal area A1 and a third temperature detection section 53 that measures the temperature of the food in the weak cooling area A2 may be provided, or one The third temperature detection unit 53 may be configured to be able to measure the temperature of the food in the normal area A1 and the temperature of the food in the weakly cooled area A2. In this embodiment, the temperature of the food in the normal area A1 and the temperature of the food in the weak cooling area A2 can be measured by one third temperature detection unit 53, and for example, the temperature of the food in the normal area A1 and the temperature of the food in the weak cooling area A2 can be measured. The temperature of the food in both areas A1 and A2 can be detected by the third temperature detection unit 53 attached on or near the boundary line L between the two areas.

Furthermore, the refrigerator 10 includes a heating section 54. The heating unit 54 can heat the temperature inside the weakly cooled area A2 to a high temperature range. As a result, the heating unit 54 has a function of maintaining the temperature of the food inside the weak cooling area A2 in the high temperature range. The heating unit 54 is connected to the control device 16 as shown in FIG. 4, and is driven under control from the control device 16. Further, the amount of heat generated by the heating section 54 is controlled by the control device 16.

The heating section 54 is provided at the outer periphery of the weak cooling area A2. In this embodiment, the heating unit 54 is embedded in the lower part of the weak cooling area A2, in this case, the bottom 114 of the refrigerator compartment 11.

The heating unit 54 is, for example, a heating wire heater that generates heat by passing electricity through a heating wire. In this embodiment, the heating unit 54 is a so-called aluminum foil heater in which a heating wire is wrapped in aluminum foil, for example. The heating section 54 is light and thin, and may be drip-proofed. In another embodiment, the heating section 54 may be a flexible planar heating element made of a heating wire wrapped in a sheet of silicone rubber, for example. The current consumption of the heating section 54 is set to, for example, about 5 to about 15 mA. Preferably, the current consumption of the heating section 54 is set to about 9 to about 11 mA. The control device 16 controls the supply of electric power to the heating section 54 . In other words, the heating unit 54 is not always in operation, but is only in operation when electric power is supplied under the control of the control device 16 .

In response to a user's operation on the operation unit 50 or when an imaging device (not shown) detects that the food 100 to be weakly cooled is accommodated in the weakly chilled area A2, the control device 16 starts the weakly chilled operation. Start. The weak cooling operation is an operation for maintaining the weak cooling area A2 in a high temperature range. The control device 16 executes the weak cooling operation according to a flowchart, an example of which is shown in FIG. 10, for example. The control device 16 includes at least one of a first temperature detection section 51, a second temperature detection section 52, a third temperature detection section 53, and a temperature detection section (not shown) that detects the temperature of a storage room in a refrigeration temperature range and the outside temperature. Mild cooling operation can be performed based on one or more detection results. In the case of the example shown in FIG. 10, the control device 16 executes the weak cooling operation based on at least the detection result of the third temperature detection section 53.

When the weak cooling operation is started (start), the control device 16 determines whether the temperature t of the food in the weak cooling area A2 detected by the third temperature detection unit 53 is lower than the first temperature x1 in step S11. Determine. The first temperature x1 can be set, for example, to 10° C., which is the lowest temperature in the high temperature range. When the detected temperature t of the third temperature detection section 53 is less than the first temperature x1 (Yes in step S11), the control device 16 advances the process to S12. When the detected temperature t is equal to or higher than the first temperature x1 (No in step S11), the control device 16 repeats the process of step S11.

The control device 16 drives the heating section 54 in step S12. As a result, the food in the weak cooling area A2 is heated. The control device 16 determines whether the detected temperature t is less than the second temperature x2 in step S13. The second temperature x2 is a temperature lower than the first temperature x1, for example, a temperature lower than the high temperature range. In this embodiment, the second temperature x2 is set to 5° C., which is the highest temperature in the refrigeration temperature zone, which is the normal temperature zone of the refrigerator compartment 11 in which the special section A is provided. If the detected temperature t is less than the second temperature x2 (Yes in step S13), the control device 16 advances the process to step S14. If the detected temperature t is equal to or higher than the second temperature x2 (No in step S13), the control device 16 advances the process to step S17.

The control device 16 reduces the rotation speed of the refrigerating blower 37 in step S14. The rotational speed after the reduction can be set, for example, within a range of about 50% to about 75% of the rotational speed during normal operation. As a result, the blowing action of the refrigerating blower 37 is reduced, and the inflow of cold air into the weakly cooled area A2 is suppressed. The control device 16 determines whether the detected temperature t is equal to or higher than the third temperature x3 in step S15. The third temperature x3 is higher than the first temperature x1 and the second temperature x2. For example, in this embodiment, the third temperature x3 is set to 15° C., which is higher than the lowest temperature in the high temperature range and lower than the highest temperature. If the detected temperature t is equal to or higher than the third temperature x3 (Yes in step S15), the control device advances the process to step S16. If the detected temperature t is less than the third temperature x3 (No in step S15), the control device repeats the process of step S15.

The control device 16 increases the rotation speed of the refrigerating blower 37 in step S16. That is, the control device 16 returns the rotation speed of the refrigerator blower 37 to the rotation speed during normal operation. This suppresses the cooling efficiency of the storage compartments 11 and 12 in the refrigeration temperature range including the normal area A1 from decreasing excessively.

The control device 16 determines whether the detected temperature t is equal to or higher than the fourth temperature x4 in step S17. The fourth temperature x4 is higher than the first temperature x1, the second temperature x2, and the third temperature x3. For example, in this embodiment, the fourth temperature x4 is set to 20° C., which is the highest temperature in the high temperature range. If the detected temperature t is equal to or higher than the fourth temperature x4 (Yes in step S17), the control device advances the process to step S18. If the detected temperature t is less than the fourth temperature x4 (No in step S17), the control device repeats the process in step S17.

The control device 16 stops driving the heating section 54 in step S18. This suppresses the food in the weak cooling area A2 from being heated more than necessary. After executing step S18, the control device advances the process to step S11 again. In this way, the control device 16 executes the weak cooling operation. Note that the control device 16 stops the weak cooling operation in response to a user's operation on the operation unit 50 or when the imaging device no longer detects food to be subjected to the weak cooling operation in the weak cooling area A2. . In this way, the control device 16 can perform a weak cooling operation.

In addition, in controlling the weak cooling operation described above, the control device 16 executed the weak cooling operation based on the temperature t detected by the third temperature detection section 53, but instead of using the temperature t detected by the third temperature detection section 53. Alternatively or in addition, a configuration may be adopted in which the weak cooling operation is performed based on the detected temperature u of the first temperature detecting section 51 and/or the detected temperature v of the second temperature detecting section 52, or both thereof.

For example, as shown in FIG. Based on this, weak cooling operation may be performed. The flowchart shown in FIG. 11 has step S21 instead of step S13, step S22 instead of step S15, and step S23 instead of step S17, compared to the flowchart of the first embodiment shown in FIG. Other processing is similar to the processing in FIG.

In step S21, the control device 16 determines whether the detected temperature v of the second temperature detection section 52 is equal to or lower than the fifth temperature x5. The fifth temperature x5 is a temperature lower than the first temperature x1, for example, a temperature lower than the high temperature range. In this embodiment, the fifth temperature x5 is set to 5° C., which is the highest temperature in the refrigeration temperature zone, which is the normal temperature zone of the refrigerator compartment 11 in which the special section A is provided. If the detected temperature v is equal to or lower than the fifth temperature x5 (Yes in step S21), the control device 16 advances the process to step S14. If the detected temperature v is higher than the fifth temperature x5 (No in step S21), the control device 16 advances the process to step S23.

The control device 16 determines whether the detected temperature u of the first temperature detection section 51 is higher than the sixth temperature x6 in step S22. The sixth temperature x6 is lower than the first temperature x1 and is equal to or lower than the fifth temperature x5, for example, below the high temperature range. For example, in this embodiment, the sixth temperature x6 is set to 5° C., which is the highest temperature in the refrigeration temperature zone, which is the normal temperature zone of the storage room 11 having the special section A. If the detected temperature u of the first temperature detection unit 51 is higher than the sixth temperature x6 (Yes in step S22), the control device advances the process to step S16. If the detected temperature u is equal to or lower than the sixth temperature x6 (No in step S22), the control device repeats the process of step S22.

In step S23, the control device 16 determines whether the detected temperature v of the second temperature detection section 52 is equal to or higher than the seventh temperature x7. The seventh temperature x7 is higher than the first temperature x1, the fifth temperature x5, and the sixth temperature x6. For example, in this embodiment, the seventh temperature x7 is set to 20° C., which is the highest temperature in the high temperature range. If the detected temperature v of the second temperature detection unit 52 is equal to or higher than the seventh temperature x7 (Yes in step S23), the control device advances the process to step S18. When the detected temperature v is less than the seventh temperature x7 (No in step S23), the control device repeats the process of step S23. In this way, the control device 16 detects the detected temperature u of the first temperature detection section 51, the detected temperature v of the second temperature detection section 52, and the detected temperature Weak cooling operation can be performed based on t.

The refrigerator 10 of this embodiment includes storage chambers 11, 12, 13, 14, and 15, coolers 41 and 42, blowers 37 and 38, and an air path 36. The storage rooms 11, 12, 13, 14, and 15 each have a normal compartment and a special compartment A separated from the normal compartment by a wall. The coolers 41 and 42 send the cold air generated by the coolers 41 and 42 to the storage chambers 11, 12, 13, 14, and 15. The air passage 36 supplies cold air to the storage chambers 11 and 12. The special section A has therein a normal region A1 that can be maintained in a normal temperature zone, in this case a chilled temperature zone, and a weakly cooled region A2 that can be maintained in a high temperature zone higher than the normal temperature zone. The special air outlet 364 in this case serves as an inlet for cold air from the air passage 36 to the special section A, and the special return outlet 363 in this case serves as an outlet for cold air from the special section A, on the normal area A1 side. It is provided.

Thereby, the cold air that has flowed into the special section A mainly circulates within the normal area A1, so that a plurality of temperature zones can be realized within one section with a simple structure. Therefore, one food product can be stored in multiple temperature zones suitable for each part, improving convenience for the user.

According to the present embodiment, the special return port 363 is located farther from the weak cooling region A2 than the special air outlet 364.

That is, the distance between the special return port 363 and the weak cooling area A2 is set longer than the distance between the special outlet 364 and the weak cooling area A2. It is provided at a position away from the special air outlet 364. Thereby, the air heading toward the special return port 363 flows further away from the weakly cooled area A2, so that the inflow of cold air from the normal area A1 to the weakly cooled area A2 can be further suppressed. Therefore, the weak cooling area A2 can be cooled more gently, and the temperature difference in the special section A can be realized more effectively.

The refrigerator 10 of this embodiment further includes a removable partition member 352 between the normal area A1 and the weakly cooled area A2, which at least partially partitions the normal area A1 and the weakly cooled area A2.

This makes it difficult for the cold air in the normal area A1 to flow into the weakly cooled area A2, and also makes it difficult for the relatively warm air in the weakly cooled area A2 to flow into the normal area A1, making it easier to maintain each desired temperature range. Become. Further, if necessary, different foods suitable for storage in different temperature zones can be stored in the normal area A1 and the weakly cooled area A2. Therefore, the special section A can be used as one space or as a space divided into two or more spaces, improving convenience for the user.

The refrigerator 10 of this embodiment includes a heating section 54 that heats the weakly cooled area A2.

Thereby, the temperature of the weak cooling area A2 can be maintained higher than the temperature of the normal area A1 more effectively by driving the heating unit 54 as necessary. That is, by actively warming the weakly cooled region A2, the temperature difference within the special section A can be realized more effectively.

The refrigerator 10 of this embodiment includes a third temperature detection section 53 as a third detection section capable of detecting the temperature of food stored in the weak cooling area A2, and a control device 16 that controls the rotation speed of the refrigerating blower 37. and. The control device 16 controls the rotation speed of the refrigerating blower 37 based on the temperature of the food detected by the third temperature detection section 53.

As a result, for example, when the food temperature in the weak cooling area A2 is too low, the cooling of the storage compartment 11 in the refrigeration temperature range including the special section A is suppressed by suppressing the air blowing action of the refrigeration blower 37, and when the temperature of the food is too low. In this case, cooling of the storage compartment 11 in the refrigeration temperature range including the special section A can be promoted by strengthening the blowing action of the refrigeration blower 37. Therefore, it is possible to control the temperature according to the condition of the food stored inside.

The refrigerator 10 of this embodiment includes a first temperature detection section 51 that detects the temperature u of the normal area A1, a second temperature detection section 52 that detects the temperature v of the weakly cooled area A2, and controls the rotation speed of the refrigerating fan 37. A control device 16 is provided. The control device 16 controls the rotation speed of the refrigerator blower 37 based on the temperature u detected by the first temperature detection section 51 and the temperature v detected by the second temperature detection section 52.

According to this, more appropriate control of the rotation speed can be executed based on both the cooling state on the side of the normal region A1 and the heating state on the side of the weakly cooling region A2. Therefore, the normal area A1 and the weakly cooled area A2 can be maintained at different desired temperatures more effectively.

(Second embodiment)
Next, a second embodiment will be described with reference to FIGS. 12 to 14. In the first embodiment, the special return port 363 is not provided in the weak cooling area A2, but the present invention is not limited to this. For example, a configuration may be adopted in which a return port serving as an air outlet is provided in each of the normal area A1 and the weakly cooling area A2, and the return port provided in at least the weakly cooling area A2 can be opened and closed. That is, when it is desired to maintain the weakly cooled area A2 in a high temperature range, the return port on the weakly cooled area A2 side is closed and the inflow of cold air into the weakly cooled area A2 is suppressed, thereby cooling the weakly cooled area A2. may be suppressed.

As shown in FIGS. 12 and 13, in addition to the special return port 363 provided on the normal area A1 side, the refrigerator 10 of the present embodiment has a second special return port 366 as a second return port, and a second special return port 366 that can be opened and closed. A device 367 is provided. The second special return port 366 is provided on the weak cooling area A2 side, and serves as an outlet for air from the weak cooling area A2. The second special return port 366 is connected to the downstream side of the refrigeration cooler 41 in the air path 36 by an auxiliary air path 365 . The opening/closing device 367 has a function of opening and closing the second special return port 366, and is, for example, a so-called damper having a closing member that rotates around an axis and a motor that rotates the closing member.

As shown in FIG. 14, the opening/closing device 367 is electrically connected to the control device 16, and under the control of the control device 16, a motor (not shown) rotates the closing member. When the opening/closing device 367 closes the second special return port 366, the flow of air from the weakly cooled area A2 to the outside of the special section A is blocked, and as a result, it becomes difficult for cold air to flow into the weakly cooled area A2. On the other hand, when the opening/closing device 367 opens the second special return port 366, air flows from the weak cooling area A2 to the outside of the special compartment A, and as a result, cold air tends to flow into the weak cooling area A2.

Note that the opening/closing device 367 may be configured to be able to adjust the degree of opening of the second special return port 366, that is, the cross-sectional area of the flow path. In this case, when the opening degree of the second special return port 366 is increased to widen the cross-sectional area of the flow path, cold air easily flows into the weak cooling area A2 and is further cooled. When the cross-sectional area of the flow path is reduced, it becomes difficult for cold air to flow into the weakly cooled region A2, and cooling of the weakly cooled region A2 is further suppressed.

For example, when the user operates the operation unit 50 to “start mild cooling operation” or when the target food 100 suitable for storage in a high temperature range is detected by an imaging device (not shown), the control device 16 opens and closes the The device 367 is driven to close the second special return port 366 or to reduce its opening degree. This makes it difficult for cold air to flow into the weakly cooled area A2 and suppresses cooling, making it easier to maintain the weakly cooled area A2 in a high temperature range. When the user operates the operation unit 50 to “stop the weak cooling operation” or when the image capturing device (not shown) does not detect the target food 100 suitable for storage in a high temperature range, the control device 16 causes the opening/closing device 367 to be activated. Drive to open the second special return port 366 or increase its opening degree. This makes it easier for cold air to flow into the weakly cooled area A2 and promotes cooling, making it easier to maintain the weakly cooled area A2 in the normal temperature range.

According to this embodiment, the same effects as those of the above embodiments are achieved.

Furthermore, the refrigerator 10 of the present embodiment includes a second special return port 366 as a second return port provided on the weak cooling area A2 side and serving as an outlet for cold air, and an opening/closing device for opening and closing the second special return port 366. 367, and a control device 16 that controls the opening degree of the opening/closing device 367. The control device 16 maintains the weakly cooled area A2 in the high temperature range by reducing or closing the opening degree of the opening/closing device 367.

As a result, the refrigerator 10 can sufficiently cool the weak cooling area A2 during normal operation, and can maintain the weak cooling area A2 in a high temperature range during weak cooling operation, improving user convenience. improves.

In addition to the special return port 363 of the normal area A1, a return port is also provided in the weak cooling area A2, and the return port of the weak cooling area A2 is operated by an opening/closing device that opens and closes the air passage from the return port of the normal area A1 to the cooler. Although the present embodiment has explained that the return port is set in the normal area A1 by closing the return port, the present invention is not limited to this. In other words, even if the normal area A1 and the weak cooling area A2 are not provided in a manner that clearly separates them, the present invention in that a plurality of return ports are provided and any one of the return ports is closed can be implemented. can.

Here, in the air passages from the coolers 41 and 42 to the air outlets provided in the storage compartments 11 and 12 in the refrigerator temperature zone and in the storage compartments 13, 14, and 15 in the freezing temperature zone, It is also conceivable to provide an opening/closing device that opens and closes the storage chambers 11, 12, 13, 14, and 15 to select which of the storage chambers 11, 12, 13, 14, and 15 the cold air generated by the coolers 41 and 42 is supplied to. As in this embodiment, a plurality of return ports are provided in any one of the storage rooms 11, 12, 13, 14, and 15, and one of the air channels is closed by a switching device in the air path from the return port to the coolers 41, 42. By closing, it is also possible to change the flow of cold air in any of the storage chambers 11, 12, 13, 14, 15. In this case, the opening and closing of the air passage by the opening/closing device may be provided so that it can be switched between the open state and the closed state, or the opening/closing device that can adjust the degree of opening and closing may be used to cool the air from multiple return ports. It is also possible to implement the method in such a manner that the amount of air flowing to the containers 41 and 42 is adjusted.

(Third embodiment)
Next, a second embodiment will be described with reference also to FIGS. 15 and 16. In the first embodiment, the special return port 363 was provided on the back side of the special compartment A, but the position of the special return port 363b, which is the outlet of the air from the special compartment A in this embodiment, is on the back side of the special compartment A. It is placed on the other side. That is, in this embodiment, the special return port 363b is provided on a different surface from the special air outlet 364. This prevents the cold air that has flowed into the normal area A1 from the special air outlet 364 from being sucked in immediately from the special return port 363b without sufficiently circulating within the normal area A1.

When the weak cooling area A2 is provided below the normal area A1, the special return port 363b can be provided on the side surface or the top surface of the special section A. When the weak cooling area A2 is provided above the normal area A1, the special return port 363b can be provided on the side surface or the bottom surface of the special section A. When the weak cooling area A2 and the normal area A1 are arranged side by side, the special return port 363b can be provided on the side surface, top surface, or bottom surface of the special section A.

In this embodiment, the special return port 363b is provided in the partition wall 39 forming the side surface of the special section A. Note that the special return port 363b may be provided in the right side wall portion 115 forming the side surface of the special section A. The special return port 363b is connected to the air path 36 on the downstream side of the refrigerator cooler 41 by an auxiliary air path 365b.

According to this embodiment, the same effects as those of the above embodiments are achieved.

Furthermore, according to this embodiment, the special air outlet 364 is provided on the back surface of the special section A. The special return port 363b is provided on a surface other than the back surface of the special section A.

As a result, the cold air flowing into the normal area A1 from the special air outlet 364 does not take a short cut near the back surface, but travels to at least a surface other than the back surface. Therefore, the cold air is prevented from being sucked into the air passage 36 without circulating within the normal area A1. Therefore, even during execution of the weak cooling operation, the cooling efficiency of the food in the normal area A1 is suppressed from decreasing.

In this embodiment, the air in the special section A is connected to the air path 36 by the auxiliary air path 365b, but the configuration is not limited thereto. For example, in other embodiments, by providing a through hole penetrating the partition wall 39 or the shelf board 34 in the thickness direction and communicating with the compartment other than the special compartment A in the refrigerator compartment 11, the compartment other than the special compartment A A configuration may be adopted in which air returns to the air passage 36 from the return port 361 via the return port 361.

(Fourth embodiment)
Next, a fourth embodiment will be described with reference to FIGS. 17 to 21. The refrigerator 10 of this embodiment has a wind direction adjustment device 60 in addition to the configuration of each of the embodiments described above. Below, an example in which a wind direction adjustment device 60 is added to the configuration of the first embodiment will be described.

The wind direction adjustment device 60 has a function of adjusting the wind direction of cold air flowing into the special section A. The wind direction adjustment device 60 is provided at the special air outlet 364 and can adjust the wind direction and volume of the cold air flowing into the special section A. In this embodiment, the wind direction adjustment device 60 is configured by arranging a plurality of rectangular blades in parallel with each other partially overlapping each other, and changing the direction of air passing between the blades by rotating the blades. It's a louver. As shown in FIGS. 17 and 18, when the normal area A1 and the weakly cooled area A2 are arranged side by side in the vertical direction, the blades are rectangular long in the left-right direction and partially overlap each other in the front-back direction. They can be arranged vertically like this. In addition, when the normal area A1 and the weak cooling area A2 are arranged side by side in the left-right direction, the blades are rectangular long in the vertical direction, and are arranged side-by-side in the left-right direction with parts of them overlapping each other in the front-rear direction. can do.

As shown in FIG. 19, the wind direction adjustment device 60 is electrically connected to the control device 16, and a motor (not shown) is driven under the control of the control device 16 to rotate the plate member. The wind direction adjustment device 60 sets the wind direction of the cold air flowing into the special section A from the special outlet 364 into a normal range in which it directs to the entire area including the normal area A1 and a weakly cool area A2, and a specific range in which it directs it to the normal area A1. It is possible.

FIG. 17 shows a state in which the wind direction is set in the normal range by the wind direction adjustment device 60. The blades are maintained in a position generally parallel to the horizontal direction. The cold air flowing into the special section A from the special outlet 364 is guided generally horizontally by the wind direction adjustment device 60 and circulates within the special section A. A part of the cold air also reaches the weakly cooled region A2 side. In this way, the entire inside of the special section A including the weakly cooled area A2 is cooled.

FIG. 18 shows a state in which the wind direction is set within a specific range by the wind direction adjustment device 60. The blades are maintained in an slanted position upward toward the front. The cold air flowing into the special section A from the special outlet 364 is guided by the wind direction adjustment device 60 in a direction away from the weakly cooled region A2, and circulates mainly within the normal region A1 within the special section A. In this way, cooling of the normal region A1 is promoted, and cooling of the weakly cooled region A2 is suppressed.

In this embodiment, as control contents during weak cooling operation, in addition to driving the heating unit 54 and lowering the rotation speed of the refrigerator blower 37, the control device 16 controls the wind direction of the wind direction adjustment device 60 to be within a specific range. Set. Thereby, it is possible to further suppress the inflow of cold air into the weak cooling area A2 during the weak cooling operation, and it is possible to more effectively realize a plurality of temperature zones within one section.

Furthermore, the control device 16 controls the temperature t of the food 100 detected by the third temperature detection section 53, the temperature u of the normal area A1 detected by the first temperature detection section 51, and the weak cooling area detected by the second temperature detection section 52. The wind direction adjustment device 60 may be controlled based on the detection result of at least one or more of the temperature v of A2 and a temperature detection section that detects the temperature of the storage room in the refrigerated temperature zone (not shown) and the outside air temperature. .

An example of the control content of the control device 16 during the weak cooling operation will be described with reference to FIG. 20. The control content of the weak cooling operation of this embodiment further includes steps S31, S32, and S33, as compared with the flowchart of the first embodiment shown in FIG.

When the weak cooling operation is started (start), the control device 16 determines whether the temperature t of the food in the weak cooling area A2 detected by the third temperature detection unit 53 is lower than the first temperature x1 in step S31. Determine. When the detected temperature t of the third temperature detection section 53 is less than the first temperature x1 (Yes in step S31), the control device 16 advances the process to S22. If the detected temperature t is equal to or higher than the first temperature x1 (No in step S31), the control device 16 repeats the process in step S31.

In step S32, the control device 16 sets the wind direction of the wind direction adjustment device 60 to a specific range. This makes it difficult for cold air to enter the weakly cooled area A2, making it easier for the temperature of the weakly cooled area A2 to rise. After that, the control device 16 advances the process to step S11.

After executing step S18, the control device 16 advances the process to step S33. In step S33, the control device 16 sets the wind direction of the wind direction adjustment device 60 to the normal range. Thereby, cold air is easily supplied to the weakly cooled area A2 in addition to the normal area A1, and the temperature in the weakly cooled area A2 is easily maintained at an appropriate temperature. Other control details are similar to the flowchart of the first embodiment shown in FIG. In this way, the weak cooling operation of this embodiment is executed.

Furthermore, in the control of the weak cooling operation shown in FIG. Instead of or in addition to the temperature t, a configuration may be adopted in which the weak cooling operation is performed based on the detected temperature u of the first temperature detecting section 51 and/or the detected temperature v of the second temperature detecting section 52, or both thereof. .

For example, as shown in FIG. Based on this, weak cooling operation may be performed. The flowchart shown in FIG. 21 has step S42 instead of step S13, step S43 instead of step S15, and step S44 instead of step S17, compared to the flowchart of the first embodiment shown in FIG. , further includes step S41. Other processing is similar to the processing in FIG. 20.

In step S41, the control device 16 determines whether the temperature t of the food in the weak cooling area A2 detected by the third temperature detection unit 53 is equal to or lower than the eighth temperature x8. The eighth temperature x8 is higher than the first temperature x1, the fifth temperature x5, and the sixth temperature x6, and is higher than the seventh temperature x7, for example, higher than the high temperature range. In this embodiment, the eighth temperature x8 is set to 20° C., which is the highest temperature in the high temperature range. When the detected temperature t of the third temperature detection unit 53 is equal to or lower than the eighth temperature x8 (Yes in step S41), the control device 16 advances the process to step S32. If the detected temperature t is higher than the eighth temperature x8 (No in step S41), the control device 16 returns the process to step S31.

In step S42, the control device 16 determines whether the detected temperature v of the second temperature detection section 52 is equal to or lower than the fifth temperature x5. If the detected temperature v is equal to or lower than the fifth temperature x5 (Yes in step S42), the control device 16 advances the process to step S14. If the detected temperature v is higher than the fifth temperature x5 (No in step S42), the control device 16 advances the process to step S44.

In step S43, the control device 16 determines whether the detected temperature u of the first temperature detection section 51 is higher than the sixth temperature x6. If the detected temperature u of the first temperature detection section 51 is higher than the sixth temperature x6 (Yes in step S43), the control device advances the process to step S16. If the detected temperature u is equal to or lower than the sixth temperature x6 (No in step S43), the control device repeats the process of step S43.

In step S44, the control device 16 determines whether the detected temperature v of the second temperature detection section 52 is equal to or higher than the seventh temperature x7. If the detected temperature v of the second temperature detection unit 52 is equal to or higher than the seventh temperature x7 (Yes in step S44), the control device advances the process to step S18. If the detected temperature v is less than the seventh temperature x7 (No in step S44), the control device repeats the process of step S44. In this way, the control device 16 detects the detected temperature u of the first temperature detection section 51, the detected temperature v of the second temperature detection section 52, and the detected temperature Weak cooling operation can be performed based on t.

According to this embodiment, the same effects as those of the above embodiments are achieved.

The refrigerator 10 of this embodiment includes a wind direction adjustment device 60 that is attached to the special air outlet 364 and is capable of adjusting the blowing direction of cold air.

The control device 16 controls the wind direction adjustment device 60 to suppress or promote the flow of cold air into the weakly cooled area A2, as necessary. For example, when the user operates the operation unit 50 to “start mild cooling operation” or when the target food 100 suitable for storage in a high temperature range is detected by an image capturing device (not shown), the control device 16 By adjusting the angle of the plate, it is possible to suppress the cold air from flowing into the weak cooling area A2. In addition, when the user operates the operation unit 50 to "stop the weak cooling operation" or when the target food 100 suitable for storage in a high temperature range is not detected by the imaging device (not shown), the control device 16 By adjusting the angle of , it is possible to start flowing cold air into the weak cooling area A2. In this way, the temperature range of the weakly cooled region A2 can be flexibly adjusted as needed, and if necessary, the inflow of cold air into the weakly cooled region A2 can be suppressed. Thereby, by not actively cooling the weakly cooled region A2, the temperature difference within the special section A can be realized more effectively.

The refrigerator 10 of this embodiment includes a third temperature detection section 53 that can detect the temperature of the food 100 stored in the weak cooling area A2. The control device 16 drives the wind direction adjustment device 60 based on the temperature t of the food 100 detected by the third temperature detection section 53 to adjust the blowing direction of the cold air.

This makes it possible to precisely control the temperature by adjusting the wind direction according to the actual temperature of the food stored inside. Therefore, the refrigerator 10 can realize the temperature difference within the special compartment A more effectively.

The refrigerator 10 of this embodiment includes a first temperature detection section 51 that detects the temperature u of the normal area A1, a second temperature detection section 52 that detects the temperature v of the weakly cooled area A2, and a control unit that drives the wind direction adjustment device 60. A device 16 is provided. The control device 16 drives the wind direction adjustment device 60 based on the temperature u detected by the first temperature detection section and the temperature v detected by the second temperature detection section 52 to adjust the blowing direction of the cold air.

According to this, more appropriate weak cooling operation control can be executed corresponding to each of the regions A1 and 2, based on both the cooling state on the normal region A1 side and the heating state on the weak cooling region A2 side. . Therefore, it is possible to more effectively maintain the food stored in the normal area A1 and the food stored in the weakly cooled area A2 at different optimal temperatures.

(Fifth embodiment)
Next, the fifth embodiment will be described with reference to FIGS. 22 to 27. In this embodiment, the refrigerator 10 includes a perforated member 70. The perforated member 70 has a function of converting the cold air flowing into the normal area A1 into a jet stream, thereby dispersing and stirring the flow direction of the air in the normal area A1.

As shown in FIGS. 22 to 24, the perforated member 70 is attached to cover at least a portion or all of the special air outlet 364. As shown in FIGS. 26 and 27, the perforated member 70 has a large number of holes 71 penetrating in the thickness direction, and at least part or all of the cold air flowing into the special section A from the air path 36 is By passing through the hole 71, the cross-sectional area of the flow path decreases, so the wind speed increases and becomes a jet stream. As the wind speed increases, the pressure decreases, so the jet draws in air from the surroundings, making it easier for the air in the normal area A1 to be stirred.

The hole 71 may have any size as long as it can convert the air passing through the hole into a jet stream, and for example, the diameter can be set within a range of about 3 to 5 mm. Each hole 71 can be formed into, for example, a circular shape, an oval shape, an oval shape, a polygonal shape including a quadrangular shape, or a slit shape, but is not limited thereto. The large number of holes 71 are arranged, for example, in a staggered pattern. The large number of holes 71 are arranged in a plurality of rows in the direction in which the normal region A1 and the weakly cooled region A2 are lined up, in this case in the vertical direction. For example, the large number of holes 71 can be arranged in 3 to 10 rows in the direction in which the normal area A1 and the weakly cooled area A2 are lined up. In this embodiment, the holes 71 are arranged in three rows in the vertical direction.

In this case, the perforated member 70 is provided in a portion of the special air outlet 364 that is further away from the weak cooling region A2, that is, on the anti-weak cooling region side. The air direction adjusting device 60 may or may not be provided in a portion of the special air outlet 364 that is not covered with the perforated member 70. In this embodiment, the air direction adjustment device 60 is provided in a portion of the special air outlet 364 that is not covered with the perforated member 70, that is, a portion that is close to the weakly cooled area A2. In this embodiment, the upper part of the special air outlet 364 is covered with a perforated member 70, and the wind direction adjustment device 60 is provided in the lower part.

When the wind direction adjustment device 60 sets the direction of the cold air passing through the wind direction adjustment device 60 in a direction away from the region where the perforated member 70 is extended forward, that is, the weak cooling region A2, the cold air passing through the wind direction adjustment device 60 The jet flow generated by passing through the perforated member 70 is more easily drawn in. This causes the air to move in multiple directions, and the effect of stirring the air by the jet within the normal area A1 is further promoted. Furthermore, since the wind direction within the normal area A1 is dispersed, drying of the food and occurrence of deformation due to the wind in a certain direction can be suppressed.

Here, since the hole portion 71 is small enough to generate a jet flow, there is a risk that the hole portion 71 may become blocked in the event of frost formation or freezing. The refrigerator 10 includes a second heating section 72 as shown in FIGS. 25 and 27. The second heating section 72 heats the area around the hole 71 to suppress frost formation, freezing, and blockage of the hole 71, and melts the ice if the hole 71 freezes. Has a function. The second heating section 72 may be, for example, a heating wire heater that generates heat by passing electricity through a heating wire, similar to the heating section 54 . The second heating section 72 may be provided on the back side of the perforated member 70 as shown in FIG. 27, or may be embedded in the perforated member 70.

As shown in FIG. 27, the second heating section 72 is arranged so as to be routed between a large number of holes 71. Thereby, the second heating section 72 can efficiently heat the surroundings of the large number of holes 71.

The second heating section 72 is electrically connected to the control device 16 as shown in FIG. 25, and heats the area around the hole 71 under the control of the control device 6. The control device 16 drives the second heating section 72 periodically or as needed. For example, the control device 16 detects the detected temperature u of the first temperature detecting section 51, the detected temperature v of the second temperature detecting section 52, the detected temperature t of the third temperature detecting section 53, and a storage room (not shown) in a refrigerated temperature range. The second heating is performed when it is determined that frost formation or freezing has occurred in the hole 71 based on the detection results of at least one or more of the temperature detection units that detect the temperature or the outside air temperature in 11 and 12. 72 can be driven.

According to this embodiment, the same effects as those of the above embodiments are achieved.

The refrigerator 10 of this embodiment includes a perforated member 70 that is provided in at least a portion of the special air outlet 364 and has a large number of holes 71 that are formed to penetrate in the thickness direction and generate a jet flow.

As a result, the cold air passes through the hole 71 having a small flow path cross-sectional area, thereby increasing the wind speed and reducing the pressure in the normal area A1. Therefore, since it becomes easier for air to flow in from the surroundings, the air is more likely to be mixed in the normal area A1, and the cold air in the normal area A1 is suppressed from entering the weakly cold area A2. Therefore, it becomes easier to maintain a plurality of regions in different temperature zones within one section.

The refrigerator 10 of this embodiment includes a second heating section 72 that heats the area around the hole 71.

Thereby, frost formation, freezing, and blockage of the holes 71 can be suppressed, and a decrease in cooling efficiency in the special section A can be suppressed.

The refrigerator 10 of this embodiment further includes a wind direction adjustment device 60 that is provided in a portion of the special air outlet 364 other than the portion where the perforated member 70 is provided, and is capable of adjusting the blowing direction of cold air. The wind direction adjustment device 60 directs the cold air passing through the wind direction adjustment device 60 to a region where the perforated member 70 is extended forward.

As a result, the degree of turbulence is further increased by actively supplying cold air by the wind direction adjustment device 60 to the area where the pressure is reduced after passing through the perforated member 70. Therefore, by further dispersing the cold air, even if the rotation speed of the refrigerator blower 37 is increased to increase the air volume, the impact of the cold air on the food 100 can be reduced. Therefore, drying of the food 100 can be suppressed and deformation of the food can be suppressed.

Note that the perforated member 70 may be configured to be able to select between a state in which it covers the special air outlet 364 and a state in which it does not cover it by rotating under the control of the control device 16. When the special air outlet 364 is covered by the perforated member 70, the cold air passing through the hole 71 generates a jet stream. If the special air outlet 364 is not covered by the perforated member 70, the cross-sectional area of the flow path will not be reduced, and no jet of cold air will be generated. Therefore, in this case, the refrigerator 10 can control whether or not to generate a jet flow, that is, to promote stirring of cold air, as necessary.

In addition, in this embodiment, the cold air that has passed through the perforated member 70 is combined with the cold air that flows in a direction different from the flow of the cold air that has passed through the perforated member 70 by the wind direction adjustment device 60, so that the cold air is directed in a certain direction. Although it has been explained that the local concentration of cold air in the special section A is suppressed by dispersing the flow of the cold air, even if the normal region A1 and the weakly cooled region A2 are not clearly separated. , the invention in this regard can be implemented.

That is, the perforated member 70 can be used together with the wind direction adjustment device 60 or alone, not only in the special air outlet 364 but also in compartments other than the special compartment A in the storage room 11, the storage compartment 12 where the special compartment A is not provided, 13, 14, and 15 can also be provided. For example, an air outlet 362 from the air passage 36 that supplies cold air generated by the refrigerating cooler 41 provided in the storage room 11 in the refrigerated temperature range, an air outlet to the vegetable compartment 12 (not shown), and storage in the frozen temperature range A perforated member 70 may be provided at one or more of the air outlets 182 from the freezer/cooler chamber 18 that supplies cold air generated by the freezer/cooler 42 provided behind the chambers 13, 14, and 15. . As a result, the stirring effect of the supplied cold air is promoted, and the wind blows gently against the food, so that drying of the food can be suppressed. In addition, for example, in a storage room suitable for storing specific foods such as the vegetable compartment 12 or the chilled room 35, it is suitable when it is desired to suppress the concentration of cold air at one location on the downstream side in the direction of travel of the cold air from the outlet. .

(Sixth embodiment)
Next, a sixth embodiment will be described with reference to FIGS. 28 and 29. In each of the embodiments described above, the special section A is provided in a part of the storage room 11, and the normal region A1 and the weakly cooled region A2 are provided within the special section A, but the present invention is not limited to this. The normal region and the weakly cooled region may be provided throughout the storage compartments 11 and 12 in the refrigerating temperature range, or may be provided in the entire storage compartments 13, 14, and 15 in the freezing temperature range. For example, the entire small freezer compartment 14, which is a relatively small storage room, can be divided into a normal region B1 and a weakly cooled region B2.

In this case, the normal area B1 is an area maintained in the freezing temperature zone which is the normal temperature zone of the storage chamber 14 in which the normal area B1 and the weakly cooled area B2 are provided. The weakly cooled region B2 is a region maintained at a higher temperature than the freezing temperature zone which is the normal temperature zone of the storage chamber 14 in which the normal region B1 and the weakly cooled region B2 are provided. For example, the temperature zone of the weak cooling region B2 can be a so-called partial temperature zone of about -3° C., which is higher than the freezing temperature zone.

In this case, as shown in FIG. 28, a non-insulated partition wall 26 is provided between the small freezer compartment 14 and the freezer compartment 15. Furthermore, a non-insulated partition wall (not shown) is provided between the small freezer compartment 14 and the ice making compartment 13.

The normal region B1 and the weakly cooled region B2 may be arranged side by side in the vertical direction, or may be arranged side by side in the left-right direction. In this embodiment, the normal region B1 and the weakly cooled region B2 are arranged side by side in the vertical direction. Further, the normal region B1 is located above the weak cooling region B2.

The freezing/cooling chamber 18 functions as an air path that supplies cold air generated by the freezing/cooling device 42 to the storage chambers 13, 14, and 15 in the freezing temperature range. The refrigeration cooler chamber 18 has a special return port 183, a special air outlet 184, and an auxiliary air passage 185. The special return port 183 is an outlet through which air is sucked in from the small freezer compartment 14 and returns to the freezer/cooler compartment 18 . The special outlet 184 is an inlet through which cold air is supplied from the freezer/cooler chamber 18 to the small freezer compartment 14 . The special return port 183 and the special air outlet 184 are both formed facing the back side of the small freezer compartment 14. The auxiliary air passage 185 is an air passage that connects the special return port 183 and the downstream side of the freezing/cooling device 42 in the freezing/cooling chamber 18 . One or more slits 143 are formed on the back side of the case 142 so as to face the special air outlet 184 , and the cold air supplied from the freezer/cooler chamber 18 through the special air outlet 184 flows into the interior of the case 142 . can flow into the country.

The special return port 183 and the special air outlet 184 are both provided at positions facing the normal area B1. That is, the special return port 183 and the special air outlet 184 are both formed to be biased toward the normal region B1 side with respect to the virtual boundary line L between the normal region B1 and the weakly cooled region B2. The cold air that has flowed into the normal region B1 from the special outlet 184 circulates within the normal region B1, and then returns from the special return port 183 to the refrigeration cooler chamber 18 via the auxiliary air passage 185.

According to this embodiment, the same effects as those of the above embodiments are achieved.

The refrigerator 10 of this embodiment includes storage chambers 11, 12, 13, 14, and 15, a refrigerator cooler 41 and a freezer cooler 42 as coolers, a refrigerator fan 37 and a freezer fan 38 as blowers, and a refrigerator as an air path. A cooler chamber 18 is provided. The refrigeration cooler 41 generates cold air that cools the storage compartments 11 and 12 in the refrigeration temperature range. The freezing cooler 42 generates cold air that cools the storage chambers 13, 14, and 15 in the freezing temperature range. The refrigeration blower 37 blows cold air generated by the refrigeration cooler 41 into the storage rooms 11 and 12. The refrigeration blower 38 blows cold air generated by the refrigeration cooler 42 into the storage rooms 13 , 14 , and 15 . The air passage 36 supplies cold air to the storage compartments 1 and 12 in the refrigeration temperature range. The freezing cooler chamber 18 supplies the cold air generated by the freezing cooler 42 to the storage chambers 13, 14, and 15 in the freezing temperature range. The storage chamber 14 has therein a normal region B1 and a weakly cooled region B2 that can be maintained at a temperature higher than the temperature range of the normal region B1. A special outlet 184 that serves as an entrance for cold air from the freezing/cooler chamber 18 to the storage chamber 14, and a special return port 183 that serves as an outlet for cold air from the storage chamber 14 are provided on the normal region B1 side.

As a result, the cold air supplied from the freezer/cooler chamber 18 mainly circulates within the normal region B1, so that excessive cooling of the weakly cooled region B2 is suppressed. Therefore, a plurality of temperature zones can be realized in one relatively small storage chamber with a simple structure. Therefore, one food can be maintained at a temperature range suitable for each part within the food.

Note that the above embodiments can be implemented in combination as appropriate. For example, in the refrigerator 10 of the fifth embodiment, a heating section that heats the weakly cooled area B2 may be provided, or a wind direction adjustment device or a perforated member may be provided. Further, a detection section capable of detecting the temperature of the normal region B1 and the weak cooling region B2, the temperature of each region, and the temperature of the food in each region is provided, and based on the detection results, the control device 16 controls the heating section, The configuration may be such that at least one or all of the refrigeration blower and the wind direction adjustment device are controlled.

The embodiments described above are presented as examples, and the scope of the invention is not intended to be limited to the embodiments described above. Further, the present invention can be partially implemented without satisfying all the configurations in any of the above embodiments. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention.
