Description

  The present invention relates to a refrigerator that has a plurality of rooms in different temperature zones and can store products to be stored having different storage optimum humidity in the same room.

  In the refrigerator for home use, it has been generally performed so far that the storage temperature is divided according to the characteristics of the stored product and the storage period. For example, if you want to use meat or fish immediately, use a chilled room at about 0 ° C, if you want to store for a long time, use a -18 ° C freezer room. -7 ° C freezer, vegetables and fruits are stored in a vegetable room at about 6 ° C.

  On the other hand, those that are desired to be stored in a cool and dark place such as oil and rice are rarely stored in a refrigerator, and are stored in a storage near the kitchen or in a predetermined storage location. In addition, vegetables and fruits, such as eggplants, cucumbers, and bananas, that are prone to low temperature damage, are often stored in a cool and dark place.

  However, in recent years, the housing structure has increased heat insulation and airtightness, and in the past it was mostly facing north, but with the integration with the living room etc., there are more kitchens facing south and east, etc. It tends to be hot and humid. For this reason, it has become difficult to secure a storage place for food to be stored in a cool and dark place, that is, “a cool place that does not require a low temperature as refrigeration is required”.

Therefore, there is a conventional refrigerator provided with a storage having a temperature of about 10 to 15 ° C. to suppress deterioration of food such as dry matter (for example, Patent Document 1).
Moreover, there exists a thing which provides a 3rd storage room in a common household refrigerator, and preserve | saves a subtropical crop, rice, etc. (for example, refer patent document 2).
Some refrigerators are provided with a third temperature chamber having a temperature of 0 to 20 ° C. and a humidity of 50% or less (for example, see Patent Document 3).
Some refrigerators include a storage container for high-humidity storage and a storage container for low-humidity storage in a temperature zone called “medium temperature” of about 10 to 18 ° C. (see, for example, Patent Document 4).
Furthermore, a high-humidity mode, a low-humidity mode, and a humidity control mode for storing brown rice that is intermediate between them are set in a low-temperature storage, and each mode is switched with an operation panel to adjust the humidity in the storage chamber (for example, , See Patent Document 5).

Japanese Patent Laid-Open No. 2-126073 (FIG. 1) Japanese Patent Laid-Open No. 10-54641 (FIG. 1) JP 2001-133110 A (FIG. 2) Japanese Patent Laid-Open No. 3-84383 (FIG. 1) JP-A-10-339547 (FIG. 2)

The storage described in Patent Document 1 has a structure capable of preserving dry matter, but does not have a structure for preserving foods that require high humidity, and has a general refrigerator room or freezer room. There is a problem that it is placed separately from the refrigerator and is expensive as the second refrigerator.
The refrigerator described in Patent Document 2 includes a third storage room in which subtropical crops, rice, and the like can be stored. However, a specific technique regarding an adjustment method related to a humidity zone is not described, and Patent Document 3 is disclosed. The third temperature chamber described in 1 is placed on the upper part of the lower refrigerator as an upper refrigerator, and has not been adapted to foods having a storage temperature of 10 ° C. or higher and requiring a high humidity zone.
According to the technique described in Patent Document 4, a storage container for high-humidity storage requires a lid mainly composed of a moisture permeable membrane, and when the lid is condensed, there is a risk of falling on food and damaging the food. .
The technology described in Patent Document 5 uses moisture generated by melting frost attached to the cooler when the compressor is turned off, and is used for humidification of a refrigerator having a freezer compartment whose internal temperature is −18 ° C. There was a possibility that sufficient humidification capacity could not be obtained with the specifications.
That is, in the techniques described in Patent Documents 1 to 5 described above, in a refrigerator in which rooms in various temperature zones such as refrigeration and freezing are integrated, there is no damage to food due to condensation, and a temperature and humidity zone corresponding to the food to be stored There is a problem that it cannot be adjusted.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a refrigerator that can be stored at a temperature equivalent to a cool and dark place and at an appropriate humidity corresponding to the food to be stored. To do.

  The refrigerator according to the present invention is a refrigerator main body having at least a freezer compartment, a vegetable compartment and a cold / dark storage room formed by compartments of the partition walls, first and second storage containers disposed vertically in the cold / dark storage room, A first cold air inlet that is provided on a partition wall between the vegetable room and the cold-dark storage room and that opens and closes the first cold air inlet for introducing the return cold air from the vegetable room into the first storage container. A first open / close means, a second cool air inlet for introducing cool air from the cooler into the second storage container, and a second cool air inlet for opening and closing the second cool air inlet. 2 opening and closing means, provided at the back of the cool / dark storage chamber below the second cool air introduction port, and flows out from the first and second storage containers. Temperature detection means to detect the temperature in the cool and dark storage room by cold air, and temperature detection Is obtained by a control means for detecting temperature of the stage to control the first and second switching means so as to preset a cool, dark place considerable temperature.

  In the present invention, the first and second cold air inlets are opened by the first and second opening / closing means to introduce the return cold air from the vegetable compartment into the first storage container, and the second storage container. The cool air from the cooler is introduced, and when the temperature in the cool and dark storage room reaches a temperature corresponding to the cool and dark place, the first and second open / close means are closed by the first and second opening / closing means. . Thereby, in the 1st storage container, it becomes high humidity by the temperature equivalent to a cool dark place, and the return cold air from a vegetable room, Therefore, the food which should be preserve | saved at the temperature equivalent to a cool dark place can be preserve | saved with appropriate humidity. It becomes possible. On the other hand, in the second storage container, the temperature is equivalent to a cool and dark place and the humidity is lowered by the cool air from the cooler. Therefore, dry matter can be stored in an optimum environment.

It is sectional drawing which cut | disconnects and shows the side surface of the refrigerator which concerns on Embodiment 1 of this invention. It is sectional drawing which expands and shows the cool dark storage room vicinity of the refrigerator of FIG. It is an expanded sectional view when the cold-dark storage room of the refrigerator which concerns on Embodiment 2 of this invention is made into a high humidity state. It is an expanded sectional view when the cold-dark storage chamber of FIG. 3 is made into a low humidity state.

Hereinafter, an embodiment of a refrigerator according to the present invention will be described with reference to FIGS. 1 to 4.
Embodiment 1 FIG.
1 is a cross-sectional view showing a side surface of a refrigerator according to Embodiment 1 of the present invention by cutting, and FIG. 2 is an enlarged cross-sectional view showing the vicinity of a cool-dark storage room of the refrigerator in FIG.

  The refrigerator shown in FIG. 1 is, for example, a household refrigerator, and the refrigerator body 1 is configured by filling a space between an outer box and an inner box with a heat insulating member such as urethane foam. In the refrigerator body 1, a plurality of rooms are formed vertically by partition walls 1 a, 1 b, 1 c that are integrally molded with the refrigerator body 1. For example, the refrigeration chamber 6 is formed at the top, the switching chamber 7 and the ice making chamber 8 disposed adjacent to the side between the partition walls 1a and 1b are formed, and vegetables and 2L are formed between the partition walls 1b and 1c. A vegetable room 9 for storing PET bottles and the like is formed, and a freezing room 10 and a cold and dark storage room 11 are formed adjacent to the lower side.

  The refrigerator body 1 is provided with doors that open and close the front opening of each room. The refrigerating room 6 is provided with a single-open door 6a with an operation panel 5 installed on the front surface. The switching room 7, the ice making room 8, the vegetable room 9, the freezing room 10 and the cold and dark storage room 11 are each drawn out. Formula doors 7a, 8a, 9a, 10a, 11a are provided. A compressor 2 is provided behind the bottom of the refrigerator body 1, a cooler 3 is installed in a space provided on the back of the vegetable compartment 9, and the cool air cooled by the cooler 3 is placed above the cooler 3. Is installed in each room.

  A circuit board 21 having control means is housed in the back wall of the refrigerator compartment 6. The drive of the compressor 2 and the air blower 4 is controlled by the control means, and the opening and closing of first and second dampers to be described later are controlled. Although not shown, the operation panel 5 is provided with a display unit for displaying the temperature in the refrigerator compartment 6, a switch for adjusting the temperature of each room, a warning lamp that is turned on when various errors occur, and the like. .

  As will be described later, the cool / dark storage chamber 11 is set to have a temperature corresponding to a cool / dark place (for example, 10 to 20 ° C.). The set temperature is the widest temperature range that is higher than the temperature set in a general household refrigerator and lower than the temperature at which a person feels cool. In addition, when preserving the vegetable which is easy to produce a disorder | damage | failure at the low temperature of about 6 degreeC, it is good also considering setting temperature as 10-15 degreeC.

  As shown in FIG. 2, the cool / dark storage chamber 11 includes a first storage container 12 disposed in the upper part of the cool / dark storage chamber 11 and a second storage container disposed in the lower part of the cool / dark storage chamber 11. 13 is provided. The first and second storage containers 12 and 13 are made of a material such as polystyrene, for example, and are box-shaped containers having an opening at the top. Food can be taken in and out from the opening. In addition, although the material of the 1st and 2nd storage containers 12 and 13 was made into polystyrene, it is not limited to this.

  A plurality of slits 12a and 13a are provided on the front surfaces of the first and second storage containers 12 and 13, respectively. The first storage container 12 is formed shorter than the depth of the second storage container 13. Thereby, the opening part of the rear part of the 1st storage container 12 is in the open state. Although not shown, the first and second storage containers 12 and 13 can be moved back and forth using a protrusion integrally formed on the inside of the side wall of the cool / dark storage chamber 11 as a rail.

  The partition wall 1c of the refrigerator main body 1 has a first cold air inlet 14 and a first cold air inlet 14 for introducing cold air from the vegetable compartment 9 into the first storage container 12 of the cold and dark storage compartment 11. A first damper 15 (first opening / closing means) that opens and closes is provided. On the back surface of the cool / dark storage chamber 11, a second cold air inlet 16 for introducing cold air from the cooler 3 into the second storage container 13, and a second damper that opens and closes the second cold air inlet 16. 17 (second opening / closing means) is provided.

  Guide plates 16 a (first cold air guide portions) that are inclined downward toward the second storage container 13 are provided at the upper and lower portions of the second cold air inlet 16. The guide plate 16a causes the cool air introduced into the cold and dark storage chamber 11 to flow into the first storage container 12 or hits the first storage container 12 to locally lower the temperature in the first storage container 12. It is provided to avoid this.

  In addition, an outlet 18 is provided below the second cold air inlet 16 on the back surface of the cold / dark storage chamber 11. The cold air flowing in the cold / dark storage chamber 11 flows out from the outlet 18 and flows toward the cooler 3 from below. The outlet 18 is provided at the lower part of the cool / dark storage chamber 11 as much as possible in order to avoid a short cycle of cool air introduced into the cool / dark storage chamber 11 from the first and second cold air inlets 14, 16. In order to ensure, a shielding plate 18a is provided at the upper part of the outlet 18 to prevent the generation of airflow. In addition, a thermistor 19 (temperature detection means) that detects the temperature in the cold and dark storage chamber 11 by the cold air flowing from the first and second storage containers 12 and 13 is installed in the vicinity of the outlet 18.

  The above-described control means is set in advance so that a temperature corresponding to a cool dark place, for example, a temperature of 10 ° C. to 20 ° C. is set, and the temperature in the cool dark storage chamber 11 detected by the thermistor 19 falls within the set temperature range. The opening and closing of the first damper 15 and the second damper 17 are controlled. That is, the control means opens the first damper 15 and the second damper 17 when the temperature in the cool / dark storage chamber 11 is outside the set temperature range, and the temperature in the cool / dark storage chamber 11 falls within the set temperature range. When entering, the first damper 15 and the second damper 17 are closed.

Here, the flow of the cool air in the cool and dark storage chamber 11 will be described with reference to FIG. In addition, the arrow in a figure has shown the flow direction of cold air.
When the first damper 15 is open, the return cold air from the vegetable compartment 9 is introduced into the first storage container 12 through the first cold air inlet 14. The vegetable room 9 stores vegetables and fruits that continue life activities during storage and exhale moisture in addition to carbon dioxide. For this reason, it becomes cold of high humidity compared with other rooms. Moreover, the temperature of the vegetable compartment 9 is about 6 degreeC, and is the closest to the preset temperature 10-20 degreeC of the cold-dark storage room 11. FIG. For this reason, it is possible to introduce cold air having a higher absolute humidity than that of returning cold air from other rooms, and efficiently introduce high-humidity cold air into the first storage container 12 in the cool and dark storage chamber 11.

  The cold air introduced into the first storage container 12 flows out from the slit 12 a provided in the front surface of the first storage container 12, and reaches the front surface of the second storage container 13 in front of the second storage container 13. It is mixed with the cold air flowing out from the provided slit 13 a and heads toward the outlet 18. The mixed cold air is blocked by the shielding plate 18 a and flows out from the outlet 18, and flows toward the cooler 3 from below. In addition, when the 1st damper 15 is closed, the return cold air of the vegetable compartment 9 returns to the downward direction of the cooler 3 via an air path (not shown) similarly to a general refrigerator.

  Further, when the second damper 17 is open, the cool air from the cooler 3 passes through the second cool air inlet 16 and is guided to the guide plate 16 a and introduced into the second storage container 13. The cold air introduced into the second storage container 13 is the cold air immediately after the water is collected by the cooler 3, and thus has the lowest humidity in the refrigerator main body 1. By introducing this into the second storage container 13, low-humidity cold air can be most efficiently introduced into the second storage container 13. This cold air flows out from the slit 13 a provided in the front surface of the second storage container 13, is mixed with the cold air that flows out from the first storage container 12 in front of the second storage container 13, and goes to the outlet 18. Head over. The mixed cold air flows out from the outlet 18 and flows from below toward the cooler 3.

Next, what is necessary is the relative humidity of the return cold air in the vegetable compartment 9.
As stored items that want to maintain high humidity at a temperature equivalent to a cool dark place, vegetables and fruits that are vulnerable to low temperatures, summer vegetables such as eggplant and cucumber, and fruits native to the tropics such as banana and pineapple. Generally, it is desirable to store vegetables at a high humidity of about 85 to 95% relative humidity. However, these vegetables are vulnerable to dew condensation, and since the vegetables and fruits themselves are alive, they breathe and release moisture, and if they are placed in a high humidity environment with nothing in the first storage container 12, Condensation occurs in this area, and if vegetables are added in this state, the vegetables may be deteriorated.

  Therefore, it is necessary to make the inside of the first storage container 12 into a high humidity environment with a small amount of vegetables and fruits. In many cases, the vegetable room 9 is almost full of various vegetables, and the return cold air at this time is approximately 90% or more in relative humidity. Therefore, assuming that the temperature of the return cold air in the vegetable room 9 is 6 ° C. and the relative humidity is 90%, and the temperature of the cool and dark storage room 11 is 13 ° C. within the set temperature range, the relative humidity is about 54%. For example, 3 long eggplants and 3 cucumbers were stored in this environment. At this time, the absolute humidity was as high as about 0.0045 [kg / kg (DA)], and the relative humidity was 99%.

By the way, if it is estimated whether the return cold air of the refrigerator room 3 having the next highest temperature after the vegetable room 9 can be directly used, if the return cold air of the refrigerator room 6 is at a temperature of 3 ° C. and a relative humidity of 95% or more, it is stored in the dark. The relative humidity of the chamber 11 is 90% or more (when the same amount of vegetables is stored at a temperature of 13 ° C.). However, in general, the food to be put in the refrigerator compartment 6 is contained in a container covered with a lid, and wrapping is used to suppress the evaporation of moisture, which is introduced into the refrigerator compartment 6 from the cooler 3. It is unlikely that the cool air will contain a lot of water and become high humidity. This is the same tendency for other rooms.
Therefore, it can be said that the cool air to be introduced when it is desired to make the cool / dark storage chamber 11 high in humidity is the return cool air of the vegetable chamber 9.

  Further, assuming that the cold air directly introduced from the cooler 3 is −25 ° C. and the relative humidity is 100%, the relative humidity at the temperature 13 ° C. of the cold / dark storage chamber 11 is 4%. Common desiccants contained in commercially available baggy foods are 10-15% relative humidity for seaweed, 20-25% for rice crackers, and 25-30% for dried shiitake mushrooms and boiled dishes. It can be seen that the relative humidity is sufficient to cope with dry matter.

  As described above, in the first embodiment, the first and second cold air inlets 14 and 16 are opened by the first and second dampers 15 and 17, and the vegetable compartment 9 is placed in the first storage container 12. When the cool air from the cooler 3 is introduced into the second storage container 13 and the temperature in the cool and dark storage chamber 11 reaches the set temperature (10 ° C. to 20 ° C.), The first and second cool air inlets 14 and 16 are closed by the first and second dampers 15 and 17. Thereby, in the 1st storage container 12, it becomes high humidity by preset temperature and the return cold air from the vegetable compartment 9, Therefore, the food which should be preserve | saved at the temperature equivalent to a cool dark place can be preserve | saved with appropriate humidity. In addition, in the second storage container 13, the temperature is equivalent to a cool dark place and the humidity is reduced by the cool air from the cooler 3, so that dry matter can be stored in an optimum environment.

  In the first embodiment, the first and second dampers 15 and 17 are opened when the temperature in the cool / dark storage chamber 11 is outside the set temperature range. You may make it adjust the opening degree of the 1st and 2nd dampers 15 and 17 according to the difference in temperature. Further, the guide plate 16 a is provided at the upper and lower portions of the second cold air inlet 16, but the guide plate 16 a may be provided only at the upper portion of the second cold air inlet 16.

Embodiment 2. FIG.
FIG. 3 is an enlarged cross-sectional view of the refrigerator according to Embodiment 2 of the present invention when the cool-dark storage room is in a high humidity state, and FIG. 4 is an enlarged cross-sectional view of the cold-dark storage room of FIG. 3 in a low humidity state. is there. In the present embodiment, the same reference numerals are assigned to the same or corresponding parts as in the first embodiment.

  3 and 4, the first storage container 12 disposed in the upper part of the cold / dark storage chamber 11 is provided with a plurality of slits 12 b on the bottom surface in addition to the front surface. A guide plate 16 b (second cold air guide portion) that is inclined upward toward the first storage container 12 is provided below the second cold air inlet 16. The guide plate 16b is provided in order to prevent the cool air from flowing into the cool / dark storage chamber 11 and short-cycled and going to the outlet 18 without circulating through the cool / dark storage chamber 11.

  The operation panel 5 includes, for example, a first switch for selecting the high humidity mode, a first switch for selecting the low humidity mode, in addition to the display unit, the switch for adjusting the set temperature, the warning lamp, and the like. Two switches (both not shown) are provided. The first and second switches may display “high humidity” and “low humidity” in the vicinity of each switch in order to identify which is the high humidity mode or the low humidity mode. In addition, it may be easy to understand by expressing more easily to the refrigerator user, for example, “vegetables / fruits” is displayed near the first switch, and “dry foods” is displayed near the second switch. Alternatively, it may be displayed with a picture similar to that.

  When the high humidity mode is selected by operating the first switch, the control means opens the first damper 15 and opens the first cold air inlet 14, and the detection temperature of the thermistor 19 is preset. When a temperature corresponding to a cool dark place (10 ° C. to 20 ° C.) is reached, the first damper 15 is closed and the first cold air inlet 14 is closed. Further, when the low humidity mode is selected by operating the second switch, the control means opens the second damper 17 and opens the second cold air inlet 16, and the detected temperature of the thermistor 19 is the same as that described above. When the temperature reaches a set temperature (10 ° C. to 20 ° C.), the second damper 17 is closed and the second cold air inlet 16 is closed.

  Next, the flow of cool air in the cool / dark storage chamber 11 will be described with reference to FIGS. First, the flow of cold air when the high humidity mode is selected will be described with reference to FIG. 3, and then the flow of cold air when the low humidity mode is selected will be described with reference to FIG. In addition, the arrow in a figure has shown the flow direction of cold air.

  When the high humidity mode is selected by operating the first switch, the control means on the circuit board 21 opens the first damper 15 and opens the first cold air inlet 14. At this time, the return cold air from the vegetable compartment 9 is introduced into the first storage container 12 through the first cold air inlet 14. The cool air in the first storage container 12 flows from the slit 12b provided on the bottom surface of the first storage container 12 into the second storage container 13 and is provided on the front surface of the first storage container 12. It flows out of 12a. Then, the cold air flowing out from the slit 12 a is mixed with the cold air flowing out from the second storage container 13 in front of the second storage container 13, and goes to the outlet 18. The mixed cold air is blocked by the shielding plate 18 a, flows out from the outlet 18, and flows toward the cooler 3 from below. On the other hand, the control means determines whether or not the detected temperature of the thermistor 19 has reached the set temperature. When the detected temperature reaches the set temperature, the first damper 15 is closed and the first cold air inlet 14 is closed. Occlude. Thereby, the temperature of the cool and dark storage chamber 11 becomes high humidity within the set temperature range.

  Next, when the low humidity mode is selected by operating the second switch, the above-described control means opens the second damper 17 and opens the second cold air inlet 16. At this time, the cool air from the cooler 3 passes through the second cool air inlet 16 and is guided to the guide plate 16 b and introduced into the first storage container 12. The cool air in the first storage container 12 flows from the slit 12b provided on the bottom surface of the first storage container 12 into the second storage container 13 and is provided on the front surface of the first storage container 12. It flows out of 12a. Then, the cold air flowing out from the slit 12 a is mixed with the cold air flowing out from the second storage container 13 in front of the second storage container 13, and goes to the outlet 18. The mixed cold air is blocked by the shielding plate 18 a, flows out from the outlet 18, and flows toward the cooler 3 from below. On the other hand, the control means determines whether or not the detected temperature of the thermistor 19 has reached the set temperature. When the detected temperature reaches the set temperature, the second damper 17 is closed and the second cold air inlet 16 is closed. Occlude. As a result, the temperature of the cool / dark storage chamber 11 is low within the set temperature range. In addition, when the 1st and 2nd dampers 15 and 17 are closed, the return cold air of the vegetable compartment 9 returns to the downward direction of the cooler 3 via an air path like a general refrigerator.

  As described above, according to the second embodiment, when the high humidity mode is selected, the first cold air inlet 14 is opened by the first damper 15 and the first and second storage containers 12, 13 are opened. When the return cold air from the vegetable room 9 is introduced and the temperature in the cold and dark storage room 11 reaches the set temperature (10 ° C. to 20 ° C.), the first damper 15 closes the first cold air inlet 14. I have to. Thereby, in the 1st and 2nd storage containers 12 and 13, it becomes high humidity by set temperature and the return cold air from the vegetable compartment 9, Therefore, food suitable for high humidity at the temperature equivalent to a cool dark place It becomes possible to save.

  When the low humidity mode is selected, the second cooler air inlet 16 is opened by the second damper 17 so that the cool air from the cooler 3 is introduced into the first and second storage containers 12 and 13. When the temperature inside the cool and dark storage chamber 11 reaches the set temperature (10 ° C. to 20 ° C.), the second cooler inlet 16 is closed by the second damper 17. Thereby, in the 1st and 2nd storage containers 12 and 13, it becomes low humidity by the preset temperature and the cool air from the cooler 3, Therefore Therefore, the dry matter suitable for low temperature humidity can be preserve | saved.

  In the second embodiment, when opening the first damper 15 or the second damper 17, the opening angle may be adjusted according to the difference between the temperature in the cool / dark storage chamber 11 and the set temperature.
