JP 2002-13864 A

  However, the conventional refrigerator has an easy-to-use layout, but it has been difficult to determine the temperature setting status of each storage room and the food to be stored, and the good layout has not been fully utilized. In particular, in the case where a plurality of compartments having different temperature zones are provided in the same storage room, there are problems in that the temperature setting status of each compartment is different and the food to be stored becomes more difficult to understand.

  This invention solves the said conventional subject, and it aims at providing the visibility which raised the visibility of the temperature condition in each division in the storage room of a refrigerator, and improved the usability more.

  In order to solve the above-described conventional problems, the refrigerator of the present invention includes a main body including a heat-insulated compartment, a plurality of compartments having different temperatures, and a light source in each compartment, The light emitted by the light source has a color tone that emits light in a preset color corresponding to the temperature zone in the compartment. When the temperature zones of the respective compartments are different in the same storage room, the color tone of the light emitted from each light source is different, so that the user can recognize at a glance that the temperature between the compartments is different in the same storage room. Is possible.

  The refrigerator of the present invention visually appeals to the user by installing a light source that emits light of such a color tone and illuminating each compartment in the storage room.

  In the refrigerator of the present invention, the user can recognize at a glance that the temperature between the compartments is different in the same storage room. In addition, the user is reminded of the temperature conditions in each compartment and the food to be stored. Therefore, when food is stored in each compartment, storage suitable for the temperature in the compartment is prevented while preventing confusion for the user. Therefore, it is possible to provide a refrigerator that is easy to use. In addition, depending on the color tone, it is possible to give the user a good impression that each compartment is clean and effectively cooled, or is effectively warmed and kept warm, As a result, the user can be satisfied.

  The invention according to claim 1 has a main body including a heat-insulated compartment, a plurality of compartments having different temperatures, and a light source in each compartment, and the light irradiated by the light source is The color tone emits light in a preset color corresponding to the temperature zone in the compartment.

  Thereby, the user can recognize the difference in temperature of each section in the same storage room at a glance from the difference in color tone, and can easily associate the storage object with the color tone. Therefore, when food is stored in each section, storage suitable for each section can be promoted while preventing user confusion.

  In addition, depending on the image of the color tone, the user can feel a clean impression and a favorable impression that the compartment is effectively cooled, and the satisfaction with the refrigerator can be increased.

  For example, the color tone of the light emitted from the light source is set so that the user is reminded of the storage object and temperature in each storage room, so that the user can easily store food in each compartment. In addition, the temperature of each section is recognized, and the food to be stored can be determined. For example, a red system that gives a warm taste for a refrigerated temperature that is relatively high or a green system that gives a mild impression, and a blue system that gives a cold impression for a relatively low freezing temperature are preferable. In addition, regarding the partial temperature and the ice temperature that are in the intermediate temperature range, it is preferable to use a purple or green system that is an intermediate color and gives a clean feeling. As for the thawing, heat-retaining and cooking functions, the color tone of red or yellow that makes warm and energy feel is preferable.

  Thus, the refrigerator according to claim 1 is subject to visual recognition and storage of the temperature state in each compartment for the user due to the difference in color tone of light emitted from the light source of each compartment in the storage chamber. Since the association of food is promoted, a refrigerator that is easy to use can be provided.

  According to a second aspect of the present invention, at least one of the sections can be switched to a plurality of temperature zones, and irradiation is performed by a light source provided in a section of the sections that can be switched to a plurality of temperature zones. The emitted light has a color tone that emits a plurality of different colors, and the color irradiated by the light source changes corresponding to each of the plurality of temperature zones.

  For this reason, by associating each temperature zone with the color of light, it becomes possible to recognize the temperature setting status in each section at a glance even when the temperature setting in the section is switched. It is easy to use because it can be stored in the correct compartment, and the storage quality can be maintained well.

  Invention of Claim 3 has a temperature detection means to detect the temperature in the said division, and it preset by the temperature in the storage chamber detected by the said temperature detection means instead of the said set temperature range The color tone is emitted.

  As a result, the actual temperature in the compartment is detected, and the light source provided in the compartment emits a color tone corresponding to that temperature, so when the temperature setting changes in the compartment or when the temperature changes in the compartment Even if the temperature setting is the same, when the temperature fluctuation is significant, the light is switched to a light of a different color tone, and it becomes possible to recognize at a glance the change in the temperature condition in each section.

  In addition, especially in the case of a storage room having a switching function that can set an arbitrary temperature zone by switching to a plurality of temperature zones in one storage room, the user can hardly understand the temperature state of the storage room, Even if food storage is confusing, even if the temperature setting of the storage room changes and the temperature in the storage room changes, the light changes to a different color and the temperature in the storage room can be seen at a glance. It becomes possible to recognize. For this reason, by associating the color tone of each light and the temperature state, it is possible to prevent the user from confusing food storage and the like, and to enlighten correct food storage, so that it is easy to use and the storage quality can be maintained well.

  According to a fourth aspect of the present invention, the light source includes a plurality of light emitting sources corresponding to a plurality of different colors. Further, by using a plurality of light sources in combination, variations in the color tone of the emitted light increase, so that the color tone of the light can be switched in various ways according to the temperature change in the section. The installation of a plurality of light sources in the same section is not limited to one place, and individual light sources may be installed in different places in the same section.

  According to the fifth aspect of the present invention, in each section, at least a part of the boundary surface between the sections is made of a light shielding material. As a result, the light shielding material can suppress the scattering of the light in each compartment to the outside, so that the amount of light irradiation in the compartment increases, and the light of each compartment is clearer to the user than in the past. Can be recognized.

  In the invention according to claim 6, in each section, at least a part of the boundary surface between the sections is provided with a heat insulating material. Thereby, it becomes possible to reduce the heat transfer between the sections set in different temperature zones. Thereby, it is possible to obtain the effect of reducing temperature fluctuations in the compartments and reducing the deterioration of energy consumption, and it is possible to set a larger temperature difference between the compartments.

  For example, in a storage room having two compartments, one can be set to a refrigeration temperature of about 1 to 5 ° C, and the other can be set to a high temperature setting of about 30 ° C to 60 ° C or a refrigeration temperature setting of about -20 ° C. Even in such a case, the temperature fluctuation in the compartment and the amount of deterioration of the energy consumption can be reduced.

  According to a seventh aspect of the present invention, the light source emits light when the door of the storage room is opened.

  Accordingly, since the user can recognize the color tone of light when the user opens the door when storing food, the recognition effect is high and the product appeal of the refrigerator at a store or the like is also high.

  According to an eighth aspect of the present invention, the refrigerator has a machine room at the top of the main body. The machine room that houses the main components of the refrigeration cycle, such as compressors and condensers, has traditionally been located at the back of the bottom of the main unit, thus reducing the volume of the storage room at the bottom of the main unit. . In addition, the average depth of women in the top of the refrigeration room is difficult to reach, so it was very unusable and a dead space.

  Therefore, by placing the machine room on the back of the uppermost part of the main body and using the space behind the uppermost refrigerator compartment that was not used effectively in the conventional refrigerator as a machine room, a part of the conventional machine room Can be used as a refrigeration / freezing space, so that the effective internal volume can be increased without increasing the external dimensions.

  According to the ninth aspect of the present invention, the compartment provided with the light source provided in the storage room includes a drawer-type storage case, and the light source is provided on the main body side outside the storage case, and at least the light source and The storage case of the facing part is made of a light transmissive material.

  As a result, when the storage case is in a storage space having a relatively small internal volume, there is a concern that the temperature in the storage case will increase due to heat generated by the light source used, but the light source is provided outside the storage case. As a result, temperature rise in the storage case can be prevented, and condensation on the light source accompanying temperature rise can be prevented. In this way, the color tone emitted from the light source can be effectively irradiated through the light-transmitting case while keeping the inside of the storage case at a low temperature, so that the inside of the storage case is shining from the user. By making the color of this light different from the color tone outside the storage case, the temperature zone in the storage case is prevented from rising, and the preservability in the storage case is further improved, It is possible to effectively notify the user of the difference in temperature range from the outside of the storage case. As a result, the user's food can be prevented from being confused and stored in the correct compartment, so that it is easy to use and the storage quality can be maintained well.

  The invention according to claim 10 is provided with a plurality of storage compartments that are insulated, and two doors that open and close the front opening of the storage compartment located at the uppermost stage among the plurality of storage compartments. And a section irradiated with a plurality of different color tones in the projection surface from the front of the larger door of the two doors.

  As a result, the storage compartment provided in the projection surface from the front of the larger door often has a large storage capacity in the storage room of the refrigerator. In such a case, the storage compartment corresponds to the large door. By irradiating a plurality of compartments with different temperature zones provided in the storage compartment with different colors, the user can easily use different storage compartments, and as a result, when storing the user's food Confusion can be prevented, and it can be stored in the correct compartment, making it easy to use and maintaining good storage quality.

  The invention according to claim 11 is provided with a plurality of storage compartments that are thermally insulated, and two doors that open and close by dividing the front opening of the storage compartment located at the uppermost stage among the plurality of storage compartments into left and right The storage chamber is divided into left and right regions at the joint portion of the two doors, the door with the smaller width in the left-right direction of the two doors is provided with a pull-out door, and the other is rotating. A temperature-switching function that includes a plurality of compartments, and at least one of the plurality of compartments can be set to a plurality of different temperature zones. The section having the temperature switching function is irradiated with a plurality of different colors on the section not having the temperature switching function. As a result, the storage room located at the uppermost stage generally has the largest storage compartment, but even in that case, the storage compartment for the drawer-type storage space and the storage space corresponding to the revolving door are properly used. In addition, by irradiating multiple compartments with different colors in different temperature zones provided in the large storage compartment corresponding to the rotary door, the user can use the large storage compartment properly. It can be done easily. As a result, the user's food can be prevented from being confused and stored in the correct compartment, so that it is easy to use and the storage quality can be maintained well.

There is also. In addition, in order to preserve wine, root vegetables, etc., the temperature may be set slightly higher, for example, around 10 ° C.

  The storage case 35 in the refrigerator compartment 2 can be switched from a refrigeration temperature to a relatively low temperature for improving the freshness of meat fish, processed meat fish foods, dairy products, etc. Set by. The vegetable room 4 is often set to a temperature setting of 2 ° C. to 7 ° C., which is equal to or slightly higher than that of the refrigerator compartment 2. The lower the temperature, the longer the freshness of the leafy vegetables can be maintained.

  The switching chamber 6 can be changed in temperature setting according to the user's settings, and can be set to a predetermined temperature from the freezer temperature zone to the refrigeration and vegetable room temperature zones, and the ice making room 5 is an independent ice storage room. There is 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 3 is usually set at −22 to −18 ° C. for frozen storage, but may be set at a low temperature of −30 ° C. or −25 ° C., for example, to improve the frozen storage state.

  An operation panel 14 is provided on the wall of the refrigerator compartment, and the temperature setting in each storage room or compartment can be changed by operating the operation panel 14.

  The main body 1 is provided with a machine room 12 in which the rear part of the freezer compartment is recessed. A second machine room 36 is provided on the upper back wall surface of the machine room 12.

  The refrigeration cycle is configured by annularly connecting a compressor 16 disposed in the machine room 12, a condenser (not shown), a capillary as a decompressor, and an evaporator 20. The evaporator 20 performs forced convection heat exchange with a cooling fan 21. The condenser (not shown) may be forcibly air-cooled using a fan, may be a natural air-cooled type that is affixed to the inside of the outer box 23 with good heat transfer, or may be arranged in a partition between the heat insulating doors in each room.

May be.

  A control board 37 for operating the refrigeration cycle is hermetically disposed in the second machine room 36 with a removable cover. Further, the machine room 12 is also substantially sealed by a back cover 15 so as to be removable.

  Moreover, the evaporator 20 which is a component apparatus of a refrigerating cycle is provided in the back part of the vegetable compartment 4 located in a middle stage with the cooling fan 21. FIG. Thereby, it is possible to maximize the internal volume and depth of the freezer compartment 3 which is the lowermost storage room.

  Note that if the middle vegetable room 4 and the lowermost freezer room 3 have the opposite configurations, the internal volume and depth of the vegetable room 4 can be maximized.

  A light source 19 for the refrigerating room is provided in the back of the refrigerating room 2 and a light source 13 for the storage case is provided on the top surface of the storage case 35 so as to illuminate the whole refrigerating room 2 and the inside of the storage case 35 when turned on. When the refrigerator door 7 is opened, the refrigerator user can recognize the light emitted from both light sources. The temperature of the refrigerator compartment 2 is constant, and the color tone of the light of the refrigerator compartment light source 19 is not particularly changed. However, the temperature inside the storage case light source 13 can be switched, and a plurality of light sources can be switched. Emission sources are provided, each emitting light of a different color. The light source is turned on and off through the control board 37.

  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 37 in accordance with the set temperature in the refrigerator, and the cooling operation is performed. The high-temperature and high-pressure refrigerant discharged by the operation of the compressor 16 dissipates heat in the condenser and is condensed and liquefied, and is decompressed by the capillary to become a low-temperature and low-pressure liquid refrigerant and reaches the evaporator 20.

  By the operation of the cooling fan 21, heat is exchanged with the air in the cabinet, and the refrigerant in the evaporator 20 is evaporated. Each room is cooled by distributing low-temperature cold air with a damper (not shown). When a plurality of evaporators or decompressors are used, the refrigerant is supplied to the necessary evaporator 20 by the flow path control means. The refrigerant exiting the evaporator 20 is sucked into the compressor 16. Thus, the inside of the cabinet is cooled by repeating the cycle operation.

  The storage case 35 in the refrigerator compartment 2 can be switched in several stages according to the user's purpose and preference. In the present embodiment, the temperature classification of the storage case 35 can be switched to a refrigeration temperature of about 5 to 0 ° C., a chilled or partial temperature of about 0 ° C. to −7 ° C., and the user can switch the temperature from the operation panel 14. If it does, it will set so that the light of the color tone preset to each temperature may be irradiated from the light source 13 for storage cases simultaneously.

  In the present embodiment, a fluorescent lamp is used as the light source 19 for the refrigerator compartment, and the interior of the refrigerator compartment 2 is always illuminated in white. However, the type and color tone of the light source are not particularly specified. In addition, an LED element is used for the light source 13 for the storage case. For example, elements that emit light in the respective wavelength regions of red, green, and blue are installed on the same base, and lighting thereof is controlled up to seven colors. Although switching is possible, other single colors or only two colors can be installed according to the number of switching temperature zones, and is not particularly specified.

  Further, although the color setting of the light source 13 for the storage case at each temperature is not particularly specified, in the present embodiment, the storage temperature is white, which is the same color as the light source 19 for the refrigerator compartment, and is at a relatively low temperature. 、 Mainly for fresh foods such as meat and fish, the partial temperature is chilled and purple that gives a clean impression, and yellowish green that gives an intermediate impression for chilled temperatures suitable for storage of dairy products and processed foods Was used.

  In addition, when the inside of the storage case 35 has the same temperature setting as that of the refrigerator compartment, the light source 13 may be turned off, thereby reducing material and running cost.

  Due to the change in the color tone of the light accompanying the change in the temperature setting thus set, the temperature setting and the temperature change inside the storage case 35 can be visually recognized, and the user can easily select the storage object from the color tone. Can be associated. Further, when the inside of the storage case 35 is set to a temperature zone different from that in the refrigerator compartment 2, the storage case light source 13 emits light of a color different from that of the refrigerator compartment light source 19, so that each compartment in the same storage compartment It is possible to make the user recognize instantly that the temperature conditions are different. For this reason, storage of food suitable for the set temperature of each section can be promoted, which is very convenient for the user.

  In addition, depending on the image of the color tone, the user can feel a clean feeling or a favorable impression that the storage case 35 is cooled effectively, and the user's satisfaction with the refrigerator can be increased. .

  The wavelength of light is not particularly limited. However, when a light source that emits light including ultraviolet light is used, the ultraviolet light floats in the compartment or adheres to the wall surface or food surface. It can act on genes and inactivate the growth function of microorganisms. As a result, the hygiene of the inside of the compartment is maintained, and it is possible to delay the discoloration and rot odor caused by microorganisms and the occurrence of netting on the food surface. 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, by providing the light source 13 including ultraviolet light in the storage chamber, it can be preserved while increasing the vitamin D content of the specific food in the storage chamber.

  In addition, the light source 13 is composed of a light source 13 having a wavelength near 650 nm which is red light together with an ultraviolet wavelength, and is a red plant in a living body that is contained a lot in apples, blueberries, strawberries, blue perilla, broccoli, eggplants, purple peaches, and the like. It is possible to most promote the production of anthocyanins, which are pigments. Since anthocyanins contain a large amount of fruits such as vegetables and fruits, the set temperature of the switching chamber 6 is suitable for the preservation of vegetables. Anthocyanins are a kind of polyphenols that have been proven to be very good for the body, as well as being effective for the eyes. is there.

  In addition, the types of light sources include miniature bulbs, LED elements, fluorescent lamps, ultraviolet lamps, and the like, but are not particularly specified, and any light source can be applied. Among them, the LED element hardly generates heat by the lamp itself, is superior to conventional fluorescent lamps and incandescent lamps in terms of running cost and durability, and is highly versatile.

  The installation of such a light source is not particularly specified as long as it can sense light when the user opens the door, and may be located at any location in each section. It is also possible to install a cover made of resin, glass or the like on the light source to protect the base from moisture, diffuse light, or strengthen it.

  Furthermore, the installation of a plurality of light sources in the same section is not limited to one place, and individual light sources may be installed in different places in the same section.

  Each light source may be turned on only when the refrigerator rotary door 7 is opened. In this case, the opening / closing of the door is detected by a detection means 17 (not shown), and the turning on / off of the light source is controlled. As a result, lipid oxidation due to light irradiation of food can be reduced and power consumption can be reduced without impairing the effect of visually recognizing the temperature zone.

  Further, in the present embodiment, the storage case 35 is a section that can be switched to a plurality of temperature zones in the refrigerator compartment 2, but the temperature of the refrigerator compartment 2 itself may be switched, and in that case, the light source for the refrigerator compartment It is also possible to change the color tone of the light emitted by 19 according to the temperature of the refrigerator compartment 2.

  The bottom of the storage shelf 8 is the top surface of the storage case 35, and by using this as a light shielding material, the light shielding member can suppress the scattering of light outside each compartment, The amount of light irradiation in the compartment is increased, and the user can clearly recognize the color of the light in each compartment as compared with the prior art. Examples of the light shielding material include an opaque resin, a colored resin, and metals, but are not particularly specified. In addition, when a material having a large light reflection effect such as metal is used, it is possible to further increase the light irradiation amount in the storage case 35 and diffuse the light throughout the storage case 35. It becomes.

  In the refrigerator according to the present embodiment, the switching chamber 6 is located below the refrigerator compartment 2 and above the vegetable compartment 4 and the freezer compartment 3. By adopting such a layout, it is possible for a woman of average height to open and close the door of the switching chamber 6 without bending down, and to take food in and out without bending down. Because it is possible, usability improves. In addition, in the vegetable room 4 that is frequently used, a woman with an average height can open and close the door without bowing down, and a heavy vegetable can be taken in and out without being crouched. There is no loss of usability. In addition, the physical burden on the user can be reduced by using a layout that can be used in an easy posture.

  In the present embodiment, the doors of the storage rooms are of a rotary type for the refrigerator compartment 2 and a drawer type for the others in consideration of usability, but these are not particularly limited.

  As described above, in the refrigerator compartment 2 of the refrigerator according to the present embodiment, the light source 13 for the storage case is provided in the storage case 35 that can be changed to a plurality of temperature zones in addition to the light source 19 for the refrigerator compartment. From the difference in the color tone of the light emitted from the camera, it is possible to make the user instantly recognize whether the temperature zone of each section is the same or different. In addition, the color tone of the irradiated light urges the user to recognize the set temperature condition, and can remind the user of food to be stored at the set temperature, thus providing a convenient refrigerator. be able to.

  In the present embodiment, the color tone emitted from the light source 13 has been mainly described as changing in correspondence with the temperature zone setting in which the storage case 35 is switched according to the temperature function. However, the temperature zone set in this way is described. In addition to the color tones fixed by the sensor, the actual temperature state detected by the temperature detection means such as a temperature sensor for detecting the temperature in the storage case 35 that changes in practice regardless of only the temperature zone setting is detected. In addition, it is also effective to emit light of a specific color tone for each constant temperature range based on the detection result in a sense that is more appropriate to the actual use situation.

  Moreover, in this Embodiment, although demonstrated in the storage case 35 which has a switching function of a temperature zone, it is not limited to this, For example, it provides in the freezer compartment 3, the vegetable compartment 4, etc., It is also effective to emit light of a specific color tone corresponding to the temperature control range that is commonly used, such as strong to weak, to give the user a sense of temperature control, prevention of overcooling and awareness of energy saving It is also possible to support good usage such as enlightenment.

  Further, for the purpose of the present invention, the light source 13 does not necessarily have a plurality of color tones in advance, but a specific color tone associated with, for example, a cooling image in an appropriate storage room or an image of stored food. However, the light source 13 may be provided for each of the storage rooms having different temperature zones, and a specific light source 13 may be provided for each storage room.

  Further, from the viewpoint of economic efficiency of standardization and sharing, the light source 13 is a light source capable of emitting a plurality of different color tones, and a specific color tone selected corresponding to the temperature zone setting of each storage room is fixed. Can also be used.

(Embodiment 2)
FIG. 2 shows a longitudinal sectional view of the refrigerator in the second embodiment of the present invention.

  In FIG. 2, the heat insulating material 18 includes a foamed urethane panel, a foamed polystyrene panel, a glass fiber laminate, a silica aerogel, a vacuum heat insulating panel, etc. at the boundary surface between the storage case 35 and the refrigerator compartment 2, but is not particularly specified. Absent. As a result, the heat insulating property of the storage case 35 is enhanced. Therefore, even when the temperature switching range is expanded from −18 ° C., which is a relatively low freezing temperature zone, to a relatively high temperature of about 40-60 ° C. The movement can be kept small. As a result, the temperature range that can be used for the user is greatly widened and user-friendliness is improved, and the temperature fluctuation inside the storage case 35 is reduced, thereby reducing frost formation on the food particularly when used at a minus temperature. As a result, the quality maintaining effect of the food can be obtained. Moreover, since installing the heat insulating material 18 and reducing the movement of heat between compartments will reduce useless energy movement, the deterioration of the energy consumption of the refrigerator main body can be reduced.

  In addition, when the heat insulating material 18 consists of a light shielding material, since the heat insulating material 18 can suppress scattering to the exterior of the light in each division, the irradiation amount of the light in a division becomes large and is used. The person can recognize the color of the light of each section more clearly than before.

  Further, by providing the storage case light source 13 in the storage case 35 that can be changed to a plurality of temperature zones in addition to the light source 19 for the refrigerator compartment, the difference in color tone of the light emitted from each light source It is possible to make the user instantly recognize whether the temperature zone is the same or different. In addition, the color tone of the irradiated light urges the user to recognize the set temperature condition, and can remind the user of food to be stored at the set temperature, thus providing a convenient refrigerator. be able to.

FIG. 3 shows a longitudinal sectional view of the refrigerator according to Embodiment 3 of the present invention.

  In FIG. 3, a machine room 12 that houses main components of the refrigeration cycle, such as a compressor 16 and a condenser (not shown), is installed at the top rear portion of the refrigerator compartment 2.

  Conventionally, the machine room 12 is located on the back of the freezer room 3 which is the lowermost part of the main body 1, and therefore the volume of the freezer room 3 is reduced. It was very difficult to use because it was out of reach without stretching, and it was a dead space.

  Since the machine room 12 is arranged on the back of the uppermost part of the main body 1 and the space behind the uppermost stage of the refrigerator compartment 2 that has not been effectively used in the conventional refrigerator is used as the machine room 12, the conventional machine room Since 12 portions can be used as a freezing space, the effective internal volume of the freezer compartment 3 can be increased without increasing the external dimensions.

  Further, by providing the storage case light source 13 in the storage case 35 that can be changed to a plurality of temperature zones in addition to the light source 19 for the refrigerator compartment, the difference in color tone of the light emitted from each light source It is possible to make the user instantly recognize whether the temperature zone is the same or different. In addition, it is possible to provide a user-friendly refrigerator because the color tone of the irradiated light prompts the user to recognize the set temperature state and can be associated with food to be stored at the set temperature. Can do.

(Embodiment 4)
FIG. 4 shows a longitudinal sectional view of the refrigerator in the fourth embodiment of the present invention.

  In FIG. 4, a light shielding member 18 is installed at the boundary surface between the storage case 35 and the refrigerator compartment 2, and the machine room 12 that houses main components of the refrigeration cycle such as the compressor 16 and a condenser (not shown) The main body 1 is installed on the rear surface of the top surface.

  FIG. 5 is a cross-sectional view of the light source in the present embodiment.

  In FIG. 5, a light source 13 includes a light source base 28 including an ultraviolet LED 26 that emits ultraviolet light having a wavelength peak of 387 nm and a blue LED 27 that emits blue light having a wavelength peak of 468 nm. However, the light source 13 cannot be directly viewed. Further, the light source 13 is fixed and installed downward on the top surface of the storage case 35 with a screw or the like (not shown) so that the ultraviolet LED 26 and the blue LED 27 illuminate the bottom surface. Further, a cushion 30 between the cover 29 and the storage case 35 and a claw 31 provided around the cover 29 prevent intrusion of water droplets and the like.

  First, since the heat insulating property of the storage case 35 is enhanced by providing the heat insulating material 18, the temperature switching width is expanded from −18 ° C., which is a relatively low temperature freezing temperature range, to a relatively high temperature of about 40-60 ° C. In this case, the heat transfer between the compartments can be kept small. As a result, the temperature range that can be used for the user is widened and the usability is improved, and the temperature fluctuation inside the storage case 35 is reduced, and the frost formation on the food particularly when used at a minus temperature is reduced. Quality maintaining effect. Moreover, since installing the heat insulating material 18 and reducing the movement of heat between compartments will reduce useless energy movement, the deterioration of the energy consumption of the refrigerator main body can be reduced.

  Conventionally, the machine room 12 is located on the back surface of the freezer room 3 which is the lowermost part of the main body 1, so that the volume of the freezer room 3 is reduced. Because there was no reach, nothing was very useful and dead space.

  The machine room 12 is arranged in the rear part of the top surface of the main body 1, and the space behind the uppermost refrigerator compartment 2 that has not been effectively used in the conventional refrigerator is used as the machine room 12. Since 12 portions can be used as a freezing space, the effective internal volume of the freezer compartment 3 can be increased without increasing the external dimensions.

  Further, in the present embodiment, the ultraviolet LED 26 and the blue LED 27 are set to light only when the storage case 35 is set to a chilled temperature, an ice temperature, or a partial temperature range from 0 ° C. to −5 ° C. on the operation panel 14. Has been.

  By using the ultraviolet light source 26 and the blue LED 27 as the light source 13, the inside of the storage case 35 becomes a slightly purpleish blue color, which is clearly different from the cold room light source 19, and the storage case 35 is a compartment with a different temperature range. Can be recognized at a glance. In addition, this color setting can give the user an impression that it is a clean room suitable for storing meat and fish.

  In addition, the chilled, ice, and partial temperature ranges from 0 ° C to -5 ° C are usually frozen at the border of whether dairy products, meat, fish, etc. with relatively short storage periods are frozen or not frozen. In addition to being able to be stored for a longer time than refrigerated storage, it is easy to use, for example, a knife can be stored more easily than frozen storage. However, the food appears to be frozen at this temperature range, but the actual freezing rate is much lower than that of freezing. Enzyme reaction, lipid oxidation reaction, and microbial growth progress gradually inside the food. The quality has deteriorated. Therefore, most of the fresh foods stored in this temperature range must be used up in about 1 or 2 weeks. However, since the food is apparently frozen, the user is likely to have an image that “the food lasts as long as frozen”, and as a result, the food that has been left for a long time often rots.

  In order to solve such a misunderstanding of the user, in this embodiment, the light source 13 is turned on only at the time of setting the chilled / ice temperature / partial temperature so that the storage case 35 is in the middle of refrigeration or freezing. It is possible to promote recognition that the temperature is set for short-term storage. Moreover, since the inside of the storage case 35 is conspicuous as the light source 13 is turned on, attention is easily paid to food inside. As a result, it is possible to prevent food from being left for a long time or forgetting to use it in the storage case when setting chilled, ice temperature, and partial temperature, and as a result, waste of the food can be prevented.

  The ultraviolet rays emitted from the ultraviolet LED 26 act on microorganism genes floating in the storage case 35 or adhering to the wall surface or food surface, and have an action of inactivating the microorganism growth function. Yes. As a result, the hygiene of the inside of the storage room can be maintained, and for food, it is possible to delay discoloration caused by microorganisms, rot odor, and netting on the food surface. By providing the light source 13 including ultraviolet light in this way, sanitary preservation with improved food preservability can be performed.

  In general, long-term irradiation of foods with ultraviolet rays promotes lipid oxidation of foods and there is a concern that the quality may deteriorate, but especially if it is irradiated during short-term storage of meat and fish for about 1 to 2 weeks. There is no problem, and since the amount of light emitted by using the light source 13 as an LED element is weaker than other lamps, the adverse effect on food is very small.

  Further, when the light source 13 includes ultraviolet light as in the present embodiment, it is necessary to sufficiently consider the safety of the user.

  For example, when the door is opened or closed in conjunction with the opening and closing of the door, it is turned off when the door is opened, but for example, it is turned on when opening and closing a pull-out door where a light source is installed in a position that cannot be seen by the eyes. You may continue. In particular, since light including the ultraviolet region is invisible to the human eye, for example, when the door is opened, light including the ultraviolet region is turned off, and highly safe light such as visible light is kept on and the door is turned on. When closed, the visible light is turned off and only the ultraviolet light is turned on, so that when the door is opened, the user can recognize the lighting of the visible light, so that the temperature range, etc. It is easy to identify at a glance and improves usability, and when the door is closed, it emits ultraviolet light that has a useful effect such as antibacterial effect by LED irradiation, etc. It is also possible to improve usability and further improve the storage stability of stored items such as food.

  In addition, although the installation location of the light source 13 in the storage case 35 is not specifically limited, when the user opens the revolving door 109 of the refrigerator compartment, the light source 13 is directly outside the range visible to the user. It is preferable to install it so as not to irritate the eyeball. For example, in the case of a refrigerator used in Japan, it is desirable to arrange the light source 13 in a portion where the light source 13 is not directly visible when a woman with average Japanese height opens the revolving door 109 in an upright state. When used in other countries, it is desirable to devise the installation position according to the average height of women in that country.

  Further, by attaching a cover to the light source 13, the user's eyeball may not be directly stimulated. At this time, the material used for the cover 29 of the light source 13 is not particularly specified, but a resin material having a high light transmittance is preferable, and if it is subjected to a satin finish, the internal light source base 28 is exposed. Rather, it will look good.

  As described above, the light source 13 is provided in the storage case 35 that can be changed to a plurality of temperature zones in addition to the light source 19 for the refrigerator compartment, so that the refrigerator compartment 2 has a color tone different from the light emitted from the light source 19 for the refrigerator compartment. It is possible for the user to instantly recognize whether the temperature zones of the two sections are the same or different. In addition, by turning on the light source 13 only when chilled, ice temperature, and partial settings are set between the refrigeration and freezing in the storage case, it is possible to recognize and store the temperature setting for storing food in a slightly frozen state. The object and their quality retention period can be recalled, and a convenient refrigerator can be provided.

  In addition, when the lowermost part of the heat insulating material 18 or the storage shelf 8 is made of a light shielding material, since these can suppress scattering of the light in the storage case 35 to the outside, the light in the storage case 35 can be suppressed. As a result, the user can recognize the color of the light of each section more clearly than before, and can enhance the action of the light source on the food.

A pull-out door 109 is disposed as a door that closes the front opening of the left region 107, and a hinged door 110 is disposed as a door that closes the front opening of the right region 108.

  The width of the pull-out door 109 is smaller than the width of the hinged door 110, and therefore the inner volume of the left region 107 is smaller than the inner volume of the right region 108. The hinge portion 111 of the hinged door 110 is provided on the side opposite to the side adjacent to the drawer door 109. In other words, the pull-out door 109 is arranged in parallel on the opposite side of the hinge opening / closing door 110 to the hinge side.

  A space 112 having a predetermined interval from the front opening of the heat insulating box 103 is provided as a cold air circulation portion behind the adjacent joint portion between the pull-out door 109 and the hinged door 110. In addition, a first partition wall 106 is provided toward the back of the upper section 104.

  That is, the upper section 104 is configured such that the left area 107 and the right area 108 communicate with each other in the space 112 in front of the first partition wall 106. In the upper section 104, the left region 107 and the right region 108 are both refrigerated rooms in a refrigerated temperature zone.

  A plurality of storage shelves 113 are provided in the left region 107 that is opened and closed by the pull-out door 109, and is configured to be pulled out integrally with the pull-out door 109.

  The right area 108 opened and closed by the hinge opening / closing door 110 on the side opposite to the pull-out door 109 is provided with a plurality of shelves 114 on which stored items are placed, and one side end portion is an inner box of a heat insulating box. 115 is provided with a shelf holder and is supported and fixed, and the other side end portion is provided with a shelf holder on the side wall surface of the first partition wall 106 and is supported and fixed.

  The storage case 116 can be used by switching to refrigeration, chilled, ice temperature, or partial temperature of about 5 ° C to -5 ° C. A storage section that is mainly partitioned to store fresh food such as meat and fish, and a rail mechanism (not shown) that allows the storage case 35 to slide back and forth is provided with an inner box 115 and a first partition. The wall 106 is provided directly or indirectly on the side wall surface.

  As shown in FIG. 6, the front end surfaces are aligned so that the front end surfaces of the plurality of shelves 114 and the storage case 35 are substantially flush with the front end surface of the first partition wall 106. That is, the space 112 provided from the front opening of the heat insulating box 102 to the front end surface of the first partition wall 106 is substantially deep in the front end of the indoor storage unit such as the shelf 114 and the storage case 35. It has an interval to the surface.

  The left area 107 is configured as a bottle storage room, and the right area 108 is configured as a refrigerator room. The bottle storage chamber serving as the left region 107 is provided with a pull-out door 109. The hinge door 110 of the refrigerator compartment serving as the right region 108 is illustrated in the space 112 opened and closed by the hinge door 110. A plurality of door shelves are provided, and a shelf holder is provided on the back surface of the hinged door 110 so as to be supported and fixed so that it can be opened and closed integrally. Thus, the storage area is divided and configured so that the user can manage and manage beverages, seasonings, other small items, eggs, and the like more easily during use.

  Therefore, the depth interval of the space 112 is set to be relatively large so as to include the depth of the door shelf. Thereby, the depth of the plurality of shelves 114 installed in the refrigerator compartment is shortened by the amount of the door shelves 205 provided, and thereby, the first partition wall 106 that aligns the front end surface and the front end surface of the shelf 114 is further improved. Since the space 112 moves backward, the depth interval of the space 112 is widened, and a sense of spaciousness through the space 112 can be further provided. In addition, the front end surface of the shelf 114 and the front end surface of the first partition wall 106 are almost aligned, so that the user and the purchaser have a sense of unity and are refreshed, and the impression is even more spacious and easy to use. Can be given.

  FIG. 7 is a cross-sectional view of the storage case in the present embodiment. In FIG. 7, the shelf 114 is provided on the top surface of the storage case 35, and the light source 13 is provided on the uppermost portion of the back surface. The light source 13 is not perpendicular to the back surface of the storage case 35, but is slightly downward. It is installed to illuminate the inside of the storage case 35.

  Also in the right side area 108 of the refrigerator compartment, a refrigerator compartment light source 19 (not shown) is installed so as to illuminate the entire compartment. When the storage case 35 is set to an intermediate temperature between refrigeration and freezing such as chilled, ice temperature, and partial from 0 ° C. to −7 ° C., the light source 13 lights light of a color different from that of the light source 19 for the refrigerator compartment. Is set to the refrigeration temperature zone, the light source 13 is turned off or light of the same color as the light source 19 for the refrigeration room is turned on.

  Thus, by providing the light source 13 of a different color in the storage case 35 that can be changed to a plurality of temperature zones in addition to the light source 19 for the refrigerator compartment, from the difference in color tone from the light emitted from the light source 19 for the refrigerator compartment, It is possible for the user to instantly recognize whether the temperature zones of the two compartments of the refrigerator compartment 2 are the same or different. In addition, when the light source 13 is turned on only when the storage case is at the intermediate temperature of refrigeration and freezing, chilled, ice temperature, and partial setting, the room is conspicuous and easy to see, especially when fresh food with a short shelf life is put It also helps prevent forgetting to use. In addition, when the light source 13 is turned on, it is possible to recognize that the temperature setting is to store food in a microfrozen state, and it is possible to recall the objects to be stored and the quality retention period thereof, thereby providing a refrigerator that is easy to use. be able to.

  Further, by installing two different light sources in the right area 108, the user can feel the interior of the storage room brighter and give a spacious and easy-to-use impression.

  In addition, a light source is not installed in the left region 107 that stores bottles of alcoholic beverages and seasonings. Many foods such as alcoholic beverages and seasonings that are stored for a relatively long period of time have a large light transmission capacity, and oxidation may be promoted by irradiating light for a long period of time. For such foods stored for a long period of time, light-shielding storage is preferable, so the left side area 107 that is not irradiated with light is shaped to facilitate storage of bottles. Thus, by dividing into the left area 107 which does not irradiate light, and the right area 108 which irradiates light, the convenience of a refrigerator can be improved and the quality of the food preserve | saved for a long term can be protected.

  As described above, in the present embodiment, the front opening of the refrigerator compartment located at the top of the plurality of storage rooms is divided into left and right areas to form the left area 107 and the right area 108, and each area is opened and closed. In the region within the projection plane from the front of the hinged door 110 which is the larger door of the two doors, the hinged door 110 is opposite to the drawer door 109 which is the two doors. By providing the light source 13 of a different color in a storage case 35 that can be changed to a plurality of temperature zones in addition to the light source 19 for the refrigerator compartment in a certain right region 108, a section irradiated with a plurality of different colors is provided. .

  As a result, the right area 108, which is the area within the projection plane from the front of the hinged door 110, which is the larger door, has a large storage capacity in the storage room of the refrigerator. By irradiating the space and the storage space of the storage case 35 with different colors, the user can easily use different storage compartments, and as a result, preventing confusion when storing the user's food, Since it can be stored in the correct compartment, it is easy to use and the storage quality can be maintained well.

  Furthermore, in the present embodiment, the left region 107, which is a section having a small width dimension, is provided with a pull-out door 109, so that the refrigerator compartment generally positioned at the uppermost level is provided with a drawer-type storage space and a rotary-type storage space. The storage space can be easily used separately from the storage space corresponding to the door, and the storage space of the shelf 114 which is a plurality of different temperature zones provided in the large storage space corresponding to the rotary door By irradiating the storage space of the storage case 35 with different colors, the user can easily use a large storage compartment. As a result, the user's food can be prevented from being confused and stored in the correct compartment, so that it is easy to use and the storage quality can be maintained well.

  The bottom of the plurality of shelves 114 in the right region 108 constitutes the top surface of the storage case 35, but when this is made of a light shielding material, these are from the light source 13 in the storage case 35. The scattering of the irradiated light to the outside can be suppressed. As a result, the amount of light irradiation in the storage case 35 is increased, and the user can recognize the color of light in each section more clearly than before.

  In addition, when a heat-insulating material is provided on the top surface of the storage case 35, when the temperature in the storage case 35 is set to a temperature other than the refrigeration temperature, temperature fluctuations are prevented in order to prevent heat transfer to other rooms. The energy consumption can be reduced.

  In addition, when a material having a large light reflection effect such as a metal is used as the light blocking material, the light irradiation amount in the storage case 35 is further increased, and the light in every case in the storage case 35 is increased. Can be diffused.

  Therefore, for example, by covering at least the storage case 35 side of the heat insulating material 18 of the present embodiment with a light-reflective material, scattering of light to the outside is suppressed by the light blocking effect, and light in the storage case 35 is reduced. In addition, the effect of heat insulation can prevent the movement of heat to other rooms, thereby suppressing temperature fluctuations and reducing energy consumption. Since light can be reflected in the storage case, the amount of light irradiation in the storage case 35 is increased, and light can be diffused everywhere. A synergistic effect of the reflection effect can be obtained.

  In addition, since the light source 13 is installed at the uppermost portion of the back surface of the storage case 35 so as to be slightly downward with respect to the back surface, the light can illuminate the entire storage case 35, so that the user recognizes the light. It becomes easy to do. In addition, since the distance to the control board provided on the back surface of the main body 101 (not shown) is also short, processing such as wiring is easy and efficient.

  As described above, the refrigerator according to the present invention can promote the recognition of the temperature of each compartment in the storage room and the storage object suitable for each compartment using a light source, and improves the usability of the refrigerator. is there. Therefore, it can be applied not only to cold insulation but also to equipment for the purpose of keeping warm, such as showcases, cooler boxes, thermal insulation coolers, and warmers, set in a plurality of different temperature zones in one storage room. In the heat insulation box which has a division, it can utilize for the improvement of usability.
