Description

  The present invention improves usability at the time of food storage by freely dividing the temperature and capacity in the refrigerator storage chamber at the same time.

Conventionally, the technology for separating the temperature and capacity in a refrigerator storage chamber can use a vegetable container in both a vegetable storage chamber and a refrigerated storage chamber at the same time. (For example, see Patent Document 1)
That is, when the slide plate, which is an opening adjusting means provided on the top cover of the vegetable container, is slid fully to the left side, the cold air intake port of the cover is opened by the slide plate. Then, cold air enters the left and right storage chambers of the vegetable container, and both chambers become refrigerated storage chambers. Further, when the slide plate is slid fully to the right side, all the cold air intakes are closed by the slide plate. Then, cold air does not enter both storage chambers of the vegetable container, and both chambers become vegetable storage chambers. Further, when the slide plate is slid to the intermediate position, the left cold air intake is opened and the right cold air intake is closed. Then, the left storage room becomes a refrigerated storage room, and the right storage room becomes a vegetable storage room.

  However, the above-described conventional technique sets the storage chamber to two temperature zones with the partition portion as a boundary, but the capacity of each temperature zone cannot be freely changed because the partition portion is fixed. This is because, for example, if there is a small amount of food stored in one temperature zone and a large amount of food stored in the other temperature zone, there will be a vacant space in the temperature zone with the smaller storage amount. There is no free space in the temperature zone where there is more. The temperature zone with a small amount of storage cannot use the vacant space to store food suitable for other temperature zones, and it is wasted in space, and the temperature zone with a large amount of storage has no vacant space. This is because foods are difficult to put in and out, and the door opening / closing time becomes long, resulting in poor cooling efficiency.

  This invention solves the said conventional subject, and it aims at providing the refrigerator which can set to a 2 temperature zone or more by setting a partition part as a boundary, changing indoor capacity | capacitance freely.

A cover that covers the upper surface of the chamber case; a cold air inlet that is formed in the storage chamber case or the cover and that takes cold air into the storage chamber case; and an opening degree adjusting means that adjusts the opening degree of the cold air inlet. The partition portion and the opening degree adjusting means operate in conjunction with each other so that the partition portion is divided into the space where the cold air intake is fully open and the space where the cold air intake is fully closed. is there.

  As a result, it is possible to set the temperature within the room to two or more temperature zones with the partition portion as a boundary while freely changing the indoor capacity.

The refrigerator of the present invention is provided with a sliding movable partition portion, a cold air inlet, and an opening degree adjusting means for taking in cold air linked to the partition portion. The temperature can be set to two or more temperature zones with the section as a boundary, and a useless space can be effectively utilized depending on the amount of food.

(Embodiment 1)
FIG. 1 is a cross-sectional view of the refrigerator according to Embodiment 1 of the present invention. FIG. 2 is a cross-sectional view from the front of the refrigerator switching chamber in the first embodiment. 3 and 4 are cross-sectional views from above the switching chamber of the refrigerator in the first embodiment.

  In FIG. 1, the refrigerator main body 1 is divided into a plurality of heat insulating compartments covered with a heat insulating material, and has a configuration in which an upper part is a revolving door type and a lower part is a drawer type. The refrigerator compartment 2 from the top, the drawer-type freezer compartment upper stage 4 provided side by side, and although not shown, an ice making room, a drawer-type freezer compartment lower stage 5 and a drawer-type vegetable compartment 6 are adjacent to the freezer compartment upper stage 4. A switching room 3 is provided in the refrigerator compartment.

  The refrigerator compartment 2 is normally set at 1 to 5 ° C. with a lower limit of the temperature at which it does not freeze for refrigerated storage, but the user can freely switch the temperature setting as described above depending on the stored items. There is also. In addition, a slightly higher temperature setting of, for example, about 10 ° C. may be used for the preservation of wine, root vegetables and the like.

  The switching chamber 3 has a sealed structure by a switching chamber case 3 a and a switching chamber case lid 7, and an opening degree adjusting means 8 for taking cold air into the switching chamber 3 is provided in a part of the switching chamber case lid 7. The temperature setting can be changed by the user's setting, and a predetermined temperature setting of −3 to 1 ° C. can be made from the partial freezing which is the fine freezing temperature range to the chilled temperature range.

  The freezer compartment upper stage 4 is set at −22 to −18 ° C. for freezing storage, and has a quick freezing function for quickly freezing food and improving the freezing quality. In some cases, cold air of −35 ° C. temporarily flows into the upper stage 4 of the freezer compartment.

  Further, the ice making chamber provided beside the freezer upper stage 4 is an independent ice storage chamber, and is provided with an automatic ice making device (not shown) to automatically produce and store ice. Although it is a freezing temperature zone for storing ice, since the purpose is storage of ice, it is possible to set a freezing temperature relatively higher than the freezing temperature zone.

  The freezer compartment lower stage 5 is usually set at −22 to −18 ° C. for frozen storage, but may be set at a low temperature of −30 or −25 ° C., for example, to improve the frozen storage state.

Is provided with a partition fixing recess 16 and an upper portion of the partition 10 is fitted therein. Further, a part of the shutter 14 is provided with a moisture permeable film 25, which controls the humidity of the switching chamber left chamber 17 when the shutter 14 is pulled out and food is put in the switching chamber left chamber 17 in a sealed state. To do.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the operation of the refrigeration cycle will be described. The refrigeration cycle is operated by a signal from the control board according to the set temperature in the cabinet, and the cooling operation is performed. The high-temperature and high-pressure refrigerant discharged by the operation of the compressor dissipates heat in the condenser to be condensed and liquefied, and is reduced in pressure by the capillary to become a low-temperature and low-pressure liquid refrigerant and reaches the evaporator.

By the operation of the cooling fan, heat is exchanged with the air in the cabinet, and the refrigerant in the evaporator evaporates. Each room is cooled by distributing low-temperature cold air with a damper. Of the cool air blown from the cooling fan, the cool air distributed upward reaches the refrigerating room 2 from the refrigerating room discharge port via the refrigerating room air passage and the refrigerating room side of the switching room damper 9. Further, a part reaches the switching chamber 3 from the discharge port for the switching chamber via the switching chamber side of the switching chamber damper 9. Here, a signal is output from a control board (not shown), the damper is operated, the flow of cold air is controlled, the temperature of the refrigerator compartment 2 and the switching chamber 3 is controlled, and the internal temperature is adjusted to a predetermined temperature. When a plurality of evaporators or decompressors are used, the refrigerant is supplied to the required evaporator by the flow path control means. The refrigerant exiting the evaporator is sucked into the compressor. Thus, the inside of the cabinet is cooled by repeating the cycle operation.

  The switching chamber 3 can be switched from a partial freezing temperature zone centered at -3 to -2 ° C to a chilled temperature zone centered at -1 ° C to 1 ° C according to the purpose and preference of the user. The size of the room can be freely changed by sliding the unit 10 to the left and right, and the chilled temperature zone and the partial temperature zone can be set at the partition 10 as a boundary. When the food stored in the switching chamber case 3a is taken out, the switching chamber case 3a, the partitioning section 10, the partitioning section slide knob 11, and the slide rail 12 are pulled out simultaneously, and the switching chamber case 3a is closed. The switching chamber case 3 a is in close contact with the switching chamber case lid 7.

  For example, when the configuration of the switching chamber 3 is in the case of FIG. 2, the partition portion 10 is located at the left third of the switching chamber case 3a. At this time, the shutter 14 provided on the switching chamber case lid 7 covers the cold air intake port 13 on the left side of the partition 10. In addition, the cold air intake 13 provided in the switching chamber case lid 7 on the right side of the partition 10 is in an open state. At this time, the cold air flowing into the switching chamber 3 from the switching chamber damper 9 enters the air passage 19, and the cold air flows in from the cold air inlet 13 on the right side of the partition 10 in the open state, and the switching chamber right chamber 18 is partially It becomes a temperature zone. In the switching chamber left chamber 17 in which the cold air inlet 13 is covered with the shutter 14, the cool air does not flow, but the cool air flows into the air passage 19 between the switching chamber 3 and the switching chamber case 3a and is indirectly cooled. It becomes a chilled temperature zone that is slightly higher than the right ventricle.

  At this time, the amount of food stored in the chilled temperature zone and the partial temperature zone can be stored at a ratio of 1: 2. In addition, since the switching chamber left chamber 17 is in a sealed state, drying due to cold air can be prevented. For example, hams and cheeses that are often stored in chilled temperature zones are easily deprived of moisture from the opening when stored after opening, and they often dry, harden or discolor, and must be discarded. Since it is in a hermetically sealed state, the moisture of the food is not easily taken away, and the state of the food before opening can be maintained for a long time. Further, since the moisture permeable membrane 25 is provided in a part of the shutter 14, for example, even when a food with a large amount of water such as cut vegetables is added, dew condensation can be prevented, and water rot and mold of vegetables can be prevented. Can be stored for a long period of time, and the food waste rate can be reduced.

  The switching chamber right chamber 18 which is a partial temperature zone is suitable for storing, for example, meat and fish. For example, in the case of chicken, when stored at 0 ° C. in the chilled temperature range, it is impossible to completely suppress the growth of adherent bacteria and the action of autolytic enzymes, and not only the storage chamber is filled with odor, Offensive odors can be transferred to other stored items and cause rot. In the vicinity of −3 ° C., which is a partial temperature zone, the water content in the cells of the meat freezes, so that the function of the autolysis enzyme of the meat and the growth of the attached bacteria can be suppressed. It can be stored for a relatively long time than the temperature range.

  In addition, since it is in a slightly frozen state, for example, when sashimi sac is stored, it can be sliced with an appropriate hardness that allows a knife to enter, so that it can be sliced easily.

  Next, when the food to be stored in the switching chamber 3 is only a chilled temperature zone such as yogurt, cheese, or ham, the state of FIG. 3 is obtained by sliding the partition 10 to the right end, and the temperature of the switching chamber 3 is reached. The belt switches to the chilled temperature zone.

As an operation at this time, the partition part slide knob 11 is manually picked from the state of FIG. 2 and is slid to the right end, but when sliding, since the upper stage of the partition part 10 is in the partition part fixing recess 16, The shutter storage case 15 provided on it also moves to the right at the same time. At this time, the shutter 14 housed in the shutter housing case 15 is pulled out, so that the cold air inlet 13 of the switching chamber case lid 7 can be covered. When the partition 10 moves to the right end as shown in FIG. 3, the switching chamber case 3a is in a sealed state, and the cold air flowing in from the switching chamber damper 9 is indirectly cooled through the air passage 19 and becomes a chilled temperature zone. .

  In addition, the partition part 10 can stabilize the temperature control of the left and right rooms partitioned by the partition part 10 by using a material having heat insulation performance.

  Next, when the same amount of food is desired to be stored in the chilled temperature zone and the partial temperature zone, the partition portion slide knob 11 is manually picked from the state of FIG. 3, and the partition portion 10 is slid to the center of the switching chamber 3. At this time, the shutter 14 is stored so as to be wound into the shutter storage case 15. When the cold air inlet 13 is opened, the cold air flowing from the switching chamber damper 9 flows from the cold air inlet 13 to the switching chamber right chamber 18, and the switching chamber right chamber 18 becomes a partial temperature zone. In the switching chamber left chamber 17, the cold air inlet 13 of the switching chamber case lid 7 is closed by the shutter, so that the cold air does not flow into the switching chamber left chamber 17, and the switching chamber 3 and the switching chamber case 3 a Since it is indirectly cooled by the cold air flowing in the air path between, it becomes a chilled temperature range slightly higher than the partial temperature range.

  The shutter 14 may be of a folding type such as a bellows in addition to a roll screen method wound around the shutter storage case 15.

  Further, the moisture permeable film 25 is not limited to the one installed on the shutter 14, and may be installed on the wall surface of the switching chamber 3 or the partition 10.

  Moreover, when the partition part 10 moves to the left or right case end and stores only in one temperature zone, the partition part 10 can be removed, and at this time, the storage capacity corresponding to the thickness of the partition part 10 is increased. Can do.

  Although not shown in the figure, a temperature sensor may be provided in the storage chamber case. In this case, more stable temperature control is possible by controlling the inflow amount of cold air by opening and closing the damper.

  Moreover, the method of flowing cool air into the switching chamber 3 is not limited to the damper, and a flap may be attached. In the case of the flap, since the duct into which the cold air flows can be provided widely, the amount of the cold air flowing into the switching chamber 3 increases, and the temperature unevenness and temperature fluctuation in the warehouse can be reduced.

  Two or more partitions may be provided. For example, when two partitions are provided, the room is divided into three by the partitions, and the temperature zone can also be divided into three by adjusting the cold air intake and the shutter.

  The switching chamber 3 is not limited to the refrigerated chamber, and may be installed in the upper stage 4 of the freezing chamber, for example. In this case, since the freezer compartment upper stage 4 has a depth longer than the width, the partition 10 can partition the room efficiently by sliding back and forth.

  Moreover, you may install a cool storage material and an aluminum plate in the switch room case 3a bottom face. As a result, when the food is introduced, the cooling speed is increased, so that the activity of adhering bacteria and self-digesting enzymes is suppressed and freshness is improved.

  As described above, in the present embodiment, a main body provided with one or more storage compartments that are thermally insulated, a partition that slides left and right, front and rear, or up and down within the storage compartment case, and the storage compartment case. A cover that closes the upper surface; a cold air inlet that is formed in the storage case or cover for taking cold air into the storage chamber; and an opening degree adjusting means that adjusts an opening degree of the cold air inlet, the opening degree adjusting means By interlocking with the partition part, the compartment in the storage room case can be freely changed, and the partition part can be set to two or more temperature zones, and the wasteful space can be effectively utilized depending on the amount of food. be able to.

FIG. 5 is a sectional view from the front of the switching chamber of the refrigerator in the second embodiment.

  A light source 20 is installed on the side surface of the switching chamber case lid 7 of the switching chamber 3. When the drawer door is opened and closed, the light emitted from the light source 20 leaks, so that the user of the refrigerator can recognize the light. In addition, a cover 21 is attached to the light source 20 so that the food 22 placed in the switching chamber 3 and the light source 20 are not in direct contact with each other.

  The switching chamber 3 has a sealed structure by a switching chamber case 3 a and a switching chamber case lid 7, and an opening degree adjusting means 8 for taking cold air into the switching chamber 3 is provided in a part of the switching chamber case lid 7. The temperature setting can be changed by the user's setting, and a predetermined temperature setting of −3 to 1 ° C. can be made from the partial freezing which is the fine freezing temperature range to the chilled temperature range.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The switching chamber left chamber 17 of the switching chamber case 3a partitioned by the partition section 10 has a sealed structure in which the cold air intake 13 is closed by the shutter 14 with the shutter 14 and is in a chilled temperature zone. The switching chamber right chamber 18 has a cold air inlet 13 in the top surface, and cold air flows into a partial temperature zone.

  The partition 10 is a material that does not transmit light, and irradiates only the switching chamber 3 to reflect light from the light source 20.

  For example, when the partition part slide knob 11 is slid to the right, the upper part of the partition part 10 is in the partition part fixing recess 16 at the same time, so the shutter storage case 15 provided on the upper part simultaneously moves to the right. . At this time, the shutter 14 housed in the shutter housing case 15 is pulled out, so that the cold air inlet 13 of the switching chamber case lid 7 can be covered. When the partition 10 is completely moved to the right end, the switching chamber case 3a is in a hermetically sealed state, and the cold air flowing in from the switching chamber damper 9 is indirectly cooled through the air passage 19 and becomes a chilled temperature zone. Further, a part of the shutter 14 is provided with a moisture permeable film 25, which serves to prevent condensation and dryness when the shutter 14 is pulled out and food is put in the switching chamber left chamber 17 in a sealed state. .

  In addition, the partition part 10 can stabilize the temperature control of the left and right rooms partitioned by the partition part 10 by using a material having heat insulation performance.

Next, when the same amount of food is desired to be stored in the chilled temperature zone and the partial temperature zone, the partition portion slide knob 11 is picked by hand, and the partition portion 10 is slid to the center of the switching chamber 3. At this time, the shutter 14 is stored so as to be wound into the shutter storage case 15. When the cold air inlet 13 is opened, the cold air flowing from the switching chamber damper 9 flows from the cold air inlet 13 to the switching chamber right chamber 18, and the switching chamber right chamber 18 becomes a partial temperature zone. In the switching chamber left chamber 17, the cold air inlet 13 of the switching chamber case lid 7 is closed by the shutter, so that the cold air does not flow into the switching chamber left chamber 17, and the switching chamber 3 and the switching chamber case 3 a Since it is indirectly cooled by the cold air flowing in the air path between, it becomes a chilled temperature range slightly higher than the partial temperature range.

  The shutter may be of a folding type such as a bellows, in addition to the method of being wound around the shutter storage case 15.

  Moreover, the method of flowing cool air into the switching chamber 3 is not limited to the damper, and a flap may be attached. In the case of the flap, since the duct into which the cold air flows can be provided widely, the amount of the cold air flowing into the switching chamber 3 increases, and the temperature unevenness and temperature fluctuation in the warehouse can be reduced.

  The right temperature room in the switching room, which is a partial temperature zone, can store fresh food for a week and can be cooked without the need for thawing, as well as less cell damage due to freezing compared to freezing. There is little outflow and it is possible to maintain the deliciousness.

  The cover 21 is subjected to, for example, glass cutting so that the light source 20 reaches the entire inside of the switching chamber left chamber 17. Thereby, even if there are few light sources, light reaches the whole inside of the switching chamber left chamber 17, and it can irradiate the whole food uniformly. Therefore, the number of light sources 20 can be minimized, the installation space for the light sources can be narrowed, and the space for the switching chamber left chamber 17 can be widened. Further, when the light source 20 has a wavelength such as ultraviolet light that is said to affect the human body, even if the user opens the switching chamber 3, the light source 20 is covered with the cover 21 so that the user is directly irradiated. It can be handled safely.

  Furthermore, by providing the cover 21 with a light guide plate capable of changing the incident angle of the light source 20 and converting the wavelength, even one type of light source can irradiate light sources of all wavelengths. Therefore, the number of light sources 20 can be minimized, the installation space for the light sources can be narrowed, and the space for the switching chamber left chamber 17 can be widened.

  In the present embodiment, the light emitted from the light source irradiates the inside of the switching chamber left chamber 17 that is a storage chamber. However, the light is provided on the side surface of the switching chamber case 3a of the switching chamber right chamber 18, and 18 may be irradiated.

  In the refrigerator of the present embodiment, it is also possible to emit light having a color tone different from normal when the temperature rises due to the opening of the switching chamber 3 door. Generally, when the door is opened for a long time and the temperature in the storage chamber rises, the food in the storage chamber tends to be adversely affected. In particular, at a negative temperature, moisture in the frozen food vaporizes due to an increase in the ambient temperature due to long-term opening of the door, and frosting may occur around the food when they are cooled again. There is a decrease in quality in terms of appearance, flavor and texture. Examples of the case where the door is opened for a long time include when food is carried in and out, or when the user forgets to close the door. In particular, when the user forgets to close the door, the opening time often takes a long time.

  In addition, although it does not specifically limit about a color tone, In the case of the wavelength of the range of 280 nm to 400 nm which is a comparatively safe ultraviolet A and B area | region with a long wavelength, the microorganisms adhering to the wall surface and food surface in a storage chamber Can be inactivated. As a result, the hygiene of the inside of the storage chamber can be maintained, and the discoloration and rot odor caused by the microorganisms of the food and the occurrence of netting on the food surface can be delayed. By providing a light source containing ultraviolet light in this way, sanitary preservation with improved food preservation can be performed.

Furthermore, some mushrooms and fish contain a lot of vitamin D precursors, and when they are irradiated with ultraviolet rays, the molecules are excited and converted into vitamin D. Therefore, it can preserve | save, raising the vitamin D content of the specific foodstuff in a storage chamber by providing the light source containing an ultraviolet light in a storage chamber.

  In addition, anthocyanins, which are red plant pigments in the body, which are abundant in apples, blueberries, strawberries, blue perilla, broccoli, eggplant, purple potatoes, etc., are produced by irradiation with light having a wavelength in the range of 290 nm to 320 nm. Promoted. In addition, anthocyanins are a kind of polyphenol, and in addition to the effects that are good for the eyes, effects such as anti-aging and anti-atherogenic effects have been verified, and they are substances that are extremely good for the body. Yes, nutritional value can be increased during storage.

  Moreover, although the light source includes a light bulb, a light emitting diode, a fluorescent lamp, an ultraviolet lamp, etc., it is not particularly specified, and any light source can be applied. Among them, the light emitting diode hardly generates heat by the lamp itself, is excellent in terms of running cost and durability, and is highly versatile.

In addition, this makes it possible to notify the user with light when calling the user some attention, and the user can recognize the attention visually, so that anyone can make a judgment at a glance.

In addition, when a user opens a storage room that wants to store stored items such as food, the state in the storage room can be visually recognized at a glance. It is possible to encourage the storage of food suitable for the food.

  The light source 20 and the cover 21 may be embedded in the switching chamber case. In this case, the amount of storage in the switching chamber 3 is increased, and an operation that is difficult to put in contact with the cover 21 when food is put into the switching chamber can be avoided.

  As described above, in the present embodiment, a main body including one or more storage compartments that are thermally insulated, a partition that slides left and right, front and rear, or up and down in the storage compartment case, and an upper surface of the storage compartment case A cover for closing cold, a cold air inlet formed in the storage case or cover for taking cold air into the storage chamber, and an opening degree adjusting means for adjusting the opening degree of the cold air inlet. The refrigerator is interlocked with the partition, and the partition is provided with a light source such as an LED. The temperature zone can be easily determined visually by illuminating the partitioned storage room. . Further, by providing the LED with a light source of a specific wavelength, it is possible to sterilize germs and the like attached to the food stored in the case, or to increase the nutritional components of the food.

FIG. 1 is a cross-sectional view of the refrigerator in the third embodiment. 6 and 7 are cross-sectional views from the front of the switching chamber of the refrigerator in the third embodiment. FIG. 8 is a cross-sectional view from above the switching chamber of the refrigerator in the third embodiment.

A light source 20 and a light source 23 are respectively installed on the case side surfaces of the switching chamber left chamber 17 and the switching chamber right chamber 18 partitioned by the partition 10 of the switching chamber 3. When the drawer-type door is opened and closed, light emitted from the light source 20 and the light source 23 leaks, so that the user of the refrigerator can recognize the light. Further, a cover 21 is attached to the light source 20 and a cover 24 is attached to the light source 23, so that the light source 30 and the food 31 placed in the switching chamber 3 are not directly in contact with each other. In addition, a right chamber light source switching sensor 40 and a left chamber light source switching sensor 41 are installed on the top surface of the switching chamber case. These sensors sense the direction of passing the sensor when the partition 10 is slid, and turn on or off the light source 20 and the light source 23.

  The switching chamber 3 has a sealed structure by a switching chamber case 3 a and a switching chamber case lid 7, and an opening degree adjusting means 8 for taking cold air into the switching chamber 3 is provided in a part of the switching chamber case lid 7. . As shown in FIG. 6, the opening degree adjusting means 8 slides the partition 10 left and right to open and close the cold air intake 13 with the shutter 14 to adjust the amount of cold air. In addition, the opening ratio of the switching chamber damper 9 to the switching chamber is controlled by the position of the partitioning portion 10, and the switching chamber left chamber 17 and the switching chamber right chamber 18 are efficiently chilled from the partial freezing that is the slight freezing temperature zone. A predetermined temperature setting of −3 to 1 ° C. can be set up to the temperature zone.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The switching chamber left chamber 17 of the switching chamber case 3a partitioned by the partition section 10 has a sealed structure in which the cold air intake 13 is closed by the shutter 14 with the shutter 14 and is in a chilled temperature zone. The switching chamber right chamber 18 has a cold air inlet 13 in the top surface, and cold air flows into a partial temperature zone.

  When the partition 10 is slid from the left side to the right side of the switching chamber 3, the volume of the chilled temperature zone of the switching chamber left chamber 17 increases, and the volume of the partial temperature zone of the switching chamber right chamber 18 decreases. This increases the volume of the chilled high temperature zone, and the switching chamber damper 9 lowers the opening rate and reduces the amount of cold air taken in. Conversely, when the partition 10 is slid from the right side to the left side of the switching chamber 3, the volume of the chilled temperature zone of the switching chamber left chamber 17 decreases and the volume of the partial temperature zone of the switching chamber right chamber 18 increases. . As a result, the volume of the partial in the low temperature zone increases, so the switching chamber damper 9 increases the opening rate and increases the amount of cold air taken in. Thereby, when the partition part 10 is slid and the volume of the switching chamber left chamber 17 and the switching chamber right chamber 18 is changed, each internal temperature can be efficiently stabilized at the set temperature.

  The partition unit 10 is a material that does not transmit light, and the light source 20 and the light source 23 are partitioned by the partition unit 10 to irradiate the switching chamber left chamber 17 and the switching chamber right chamber 18, respectively.

  In addition, the partition part 10 can stabilize the temperature control of the left and right rooms partitioned by the partition part 10 efficiently by using a material having heat insulating performance.

  When the partition 10 is slid from the position of FIG. 6 to the position of FIG. 7, when the partition section slide knob 11 is slid to the right to the position of FIG. 7, the upper stage of the partition 10 simultaneously enters the partition fixing recess 16. Therefore, the shutter storage case 15 provided on the same also moves to the right at the same time. At this time, the shutter 14 housed in the shutter housing case 15 is pulled out, so that the cold air inlet 13 of the switching chamber case lid 7 can be covered. Further, since the space of the switching chamber right chamber 18 is lost and the capacity of the chilled temperature zone of the switching chamber left chamber 17 is increased, the opening rate of the switching chamber damper 9 is lowered, and the cold air flowing from the switching chamber damper 9 is wind It is indirectly cooled through the path 19 and becomes only a chilled temperature zone. When the partition unit 10 is slid, the partition unit 10 passes through the right ventricular light source switching sensor from the left to the right, and the light source 23 is turned off by detecting this sensor. Only the light source 20 is turned on, and it can be easily confirmed visually that the switching chamber 3 is in one temperature zone. Further, turning off the light source 23 also has an energy saving effect.

Next, when the partition portion 10 is returned from the position of FIG. 7 to the position of FIG. 6, when the partition portion slide knob 11 is slid to the left, the upper portion of the partition portion 10 is in the partition portion fixing recess 16 at the same time. In addition, the shutter storage case 15 provided on the same moves to the left at the same time. At this time, the shutter 14 is engulfed in the shutter storage case 15, thereby opening the cold air inlet 13 of the switching chamber case lid 7. Further, the capacity of the partial temperature zone of the switching chamber right chamber 18 is increased, and the capacity of the chilled temperature zone of the switching chamber left chamber 17 is decreased, so that the opening rate of the switching chamber damper 9 is increased. The inflowing cool air flows into the cool air intake 13 of the switching chamber right chamber 18 opened through the air passage 19 and indirectly cools the case of the switching chamber left chamber 17. As a result, the switching chamber right chamber 18 is efficiently stabilized in the partial temperature zone and the switching chamber left chamber 17 is stabilized in the chilled temperature zone. When the partition portion 10 is slid, the partition portion 10 moves the right chamber light source switching sensor 40 to the right. The light source 23 is turned on when this sensor senses it. Accordingly, the light source 20 and the light source 23 are turned on with the partition 10 as a boundary, and it can be easily confirmed visually that the temperature is in the two temperature zones.

  The operation of sliding the partition 10 to the left side of the switching chamber 3 to eliminate the space of the switching chamber left chamber 17 and setting the partial temperature zone of the switching chamber right chamber 18 is also the same, and thus will be omitted.

  A temperature sensor may be installed in the switching chamber 3. Thereby, the inflow amount of the cold air from the switching chamber damper 9 can be controlled more accurately, and the temperature fluctuation in the switching chamber 3 can be suppressed.

  Moreover, the method of flowing cool air into the switching chamber 3 is not limited to the damper, and a flap may be attached. In the case of the flap, since the duct into which the cold air flows can be provided widely, the amount of the cold air flowing into the switching chamber 3 increases, and the temperature unevenness and temperature fluctuation in the warehouse can be reduced.

  In addition to the roll screen method that is wound around the shutter storage case 15, the shutter may be a folding type like a bellows or a sliding type that overlaps in layers.

  The switching room right chamber 18 is a partial temperature zone that can store fresh food for a week and can be cooked without the need for thawing. It is possible to maintain the taste.

  The cover 21 and the cover 24 are subjected to, for example, glass cutting so that the light source 20 and the light source 23 reach the entire interior of the switching chamber left chamber 17 and the switching chamber right chamber 18, respectively. Thereby, even if there are few light sources, light reaches the whole inside of the switching chamber left chamber 17 and the switching chamber right chamber 18, and the whole food can be irradiated with light evenly. Therefore, the number of light sources 20 and light sources 23 can be minimized, the installation space for the light sources can be narrowed, and the space for the switching chamber left chamber 17 and the switching chamber right chamber 18 can be expanded. Further, when the light source 20 or the light source 23 has a wavelength such as ultraviolet light that is said to affect the human body, the cover 21 and the cover 24 cover the light source 20 or the light source 23 even if the user opens the switching chamber 3. Thus, the user is not directly irradiated and can be handled safely.

  Furthermore, by providing the cover 21 and the cover 24 with a pupil disk capable of changing the wavelength by changing the incident angle of the light source 20 and the light source 23, even one type of light source can irradiate light sources of all wavelengths. . Therefore, the number of light sources 20 and light sources 23 can be minimized, the installation space for the light sources can be narrowed, and the space for the switching chamber left chamber 17 and the switching chamber right chamber can be expanded.

In the refrigerator of the present embodiment, it is also possible to emit light having a color tone different from normal when the temperature rises due to the opening of the switching chamber 3 door. Generally, when the door is opened for a long time and the temperature in the storage chamber rises, the food in the storage chamber tends to be adversely affected. In particular, at a negative temperature, moisture in the frozen food vaporizes due to an increase in the ambient temperature due to long-term opening of the door, and frosting may occur around the food when they are cooled again. There is a decrease in quality in terms of appearance, flavor and texture. Examples of the case where the door is opened for a long time include when food is carried in and out, or when the user forgets to close the door. In particular, when the user forgets to close the door, the opening time often takes a long time.

  In addition, although it does not specifically limit about a color tone, In the case of the wavelength of the range of 280 nm to 400 nm which is a comparatively safe ultraviolet A and B area | region with a long wavelength, the microorganisms adhering to the wall surface and food surface in a storage chamber Can be inactivated. As a result, the hygiene of the inside of the storage chamber can be maintained, and the discoloration and rot odor caused by the microorganisms of the food and the occurrence of netting on the food surface can be delayed. By providing a light source containing ultraviolet light in this way, sanitary preservation with improved food preservation can be performed.

Furthermore, some mushrooms and fish contain a lot of vitamin D precursors, and when they are irradiated with ultraviolet rays, the molecules are excited and converted into vitamin D. Therefore, it can preserve | save, raising the vitamin D content of the specific foodstuff in a storage chamber by providing the light source containing an ultraviolet light in a storage chamber.

  In addition, anthocyanins, which are red plant pigments in the body, which are abundant in apples, blueberries, strawberries, blue perilla, broccoli, eggplant, purple potatoes, etc., are produced by irradiation with light having a wavelength in the range of 290 nm to 320 nm. Promoted. In addition, anthocyanins are a kind of polyphenol, and in addition to the effects that are good for the eyes, effects such as anti-aging and anti-atherogenic effects have been verified, and they are substances that are extremely good for the body. Yes, nutritional value can be increased during storage.

  Moreover, although the light source includes a light bulb, a light emitting diode, a fluorescent lamp, an ultraviolet lamp, etc., it is not particularly specified, and any light source can be applied. Among them, the light emitting diode hardly generates heat by the lamp itself, is excellent in terms of running cost and durability, and is highly versatile.

In addition, this makes it possible to notify the user with light when calling the user some attention, and the user can recognize the attention visually, so that anyone can make a judgment at a glance.

In addition, when the user opens a storage room that wants to store stored items such as food, the user can visually recognize the state of the storage room at a glance, thus preventing misrecognition of the user. It is possible to encourage the storage of food suitable for the food.

  The light source 20, the light source 23, the cover 21, and the cover 24 may be embedded in the switching chamber case. In this case, the amount of storage in the switching chamber 3 is increased, and an operation that is difficult to put in contact with the cover 21 or the cover 24 when food is put into the switching chamber can be avoided.

As described above, in the present embodiment, a main body including one or more storage compartments that are thermally insulated, a partition that slides left and right, front and rear, or up and down in the storage compartment case, and an upper surface of the storage compartment case A cover for closing cold, a cold air inlet formed in the storage case or cover for taking cold air into the storage chamber, and an opening degree adjusting means for adjusting the opening degree of the cold air inlet. The refrigerator is interlocked with a partition, and the storage room is provided with a plurality of light sources such as LEDs, and can be set to two or more temperature zones with the partition as a boundary, and is partitioned storage By illuminating the room, the temperature zone can be easily determined visually. In addition, when the temperature zone is switched from two to one and from one to two at the position of the partition, the temperature inside the warehouse can be visually notified by turning off or turning on the light source, and a wasteful light source Saving energy by not using. In addition, by linking the opening rate of the switching chamber damper with the position of the partition, the amount of cool air flowing into the switching chamber can be controlled, and the switching chamber can be efficiently cooled. Further, by providing the LED with a light source of a specific wavelength, it is possible to sterilize germs and the like attached to the food stored in the case, or to increase the nutritional components of the food.

  As described above, the refrigerator according to the present invention can be set to two or more temperature zones with the partition part as a boundary while freely changing the compartment in the storage room case by sliding the partition part. It is possible to effectively use a useless space. Therefore, it can be applied not only to household refrigerators but also to commercial refrigerators and wine cellars.
