Japanese Unexamined Patent Publication No. 2000-186883

  However, in the conventional refrigerator, it is difficult to identify foods to be stored in each room, and it is difficult to check the temperature state in the storage. In particular, in a switching room capable of switching from a refrigeration temperature to a plurality of temperature zones such as a freezing temperature and an intermediate temperature thereof, it is difficult to identify completion of switching when the set temperature is switched.

  The present invention solves the above-described conventional problems, and an object of the present invention is to provide a refrigerator that easily performs temperature identification up to a set temperature in each room of the refrigerator and further improves usability.

  In order to solve the above-described conventional problems, the refrigerator of the present invention has a refrigerator main body including a storage room partitioned by heat insulation, and a light source provided in the storage room, and the light irradiated by the light source is The color tone is switched in accordance with the set temperature, and when the set temperature is changed, the indoor color tone is changed stepwise until the set temperature is reached.

  Thereby, when the set temperature of the storage room is changed, the color tone changes step by step until the set temperature is reached, and anyone can identify the completion of switching at a glance. The temperature in the cabinet is displayed by color instead of numerical value, so it is possible to give a strong impression to the emotional effect of vague colors that each individual has, and it becomes easier to realize the cooling content than the quantitative display by numerical value. The door opening / closing frequency and the door opening time are easily controlled.

  In the refrigerator of the present invention, when the internal temperature is changed, the internal temperature is displayed not by the numerical value but by the color, so it is possible to give a strong impression to the vague color emotional effect that each individual has. However, it is possible to identify the completion of switching at a glance and provide a convenient refrigerator.

  The invention according to claim 1 is a refrigerator having a refrigerator body having a storage compartment partitioned by heat insulation and a light source provided in the storage compartment, and the light irradiated by the light source is in accordance with the set temperature. It has a function of switching the color tone, and when the setting is changed, the indoor color tone is changed in stages until the set temperature is reached. Thereby, it is possible to visually recognize the completion of temperature setting in the storage chamber due to a change in color tone, and it becomes easy to control the frequency of opening and closing the door and the opening time of the door by the user. Further, the storage object can be easily associated with the color tone when the setting is completed, and when storing the food in each storage room, it is possible to promote storage suitable for each storage room while preventing the user from being confused.

  Moreover, depending on the image of the color tone, the user can feel a clean feeling and a favorable impression that the interior of the storage room is effectively cooled, and the satisfaction with the refrigerator can be increased.

  As described above, the refrigerator according to claim 1 can visually recognize completion of temperature setting in the storage chamber by the color tone of light emitted from the light source, and can be used when the set temperature is reached. Since the user is reminded of food to be stored, it is possible to provide a refrigerator that is easy to use and is easy to control the frequency of opening and closing the door and the opening time of the door.

  According to a second aspect of the present invention, in the first aspect of the present invention, the light irradiated by the light source includes a plurality of light emitting sources corresponding to a plurality of different colors. When the temperature setting is switched or when the temperature fluctuation in the storage chamber is significant, the light is switched to a different light, and the change in the temperature state in the storage chamber can be recognized at a glance. 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 storage chamber. For example, when changing the set temperature, until it reaches the set temperature, in addition to the color tone suitable for the set temperature above, by illuminating with white light, it shows a color tone lighter than the color tone suitable for the set temperature and set As the temperature approaches, the user can visually appeal to the user by gradually reducing the white light and changing it to a darker tone.

  The invention described in claim 3 is the invention described in claim 1 or 2, wherein when the temperature rises due to the door opening, light having a color tone different from that of the normal time is emitted.

  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 taken in and out, or when the door is forgotten to close. In particular, it is effective to call attention with light in the case of mischief by an infant or child, or when the door cannot be completely closed due to lack of height and power.

  In addition, the function of notifying the door opening by sound has existed in the past, but it can be replaced with a visually appealing means such as the present invention, or by using it together, even in the hearing impaired, the inside of the warehouse due to forgetting to close the door Recognition of temperature rise is possible.

  In the invention described in this claim, by switching the color tone of the light emitted from the light source to a specific color when the temperature in the storage room rises, the user can recognize the long-term opening of the door, such as food or ice in the storage room. Can protect the quality. In addition, since it is possible to prevent an increase in power consumption for temperature recovery after the door is opened for a long time, an effect of reducing the amount of energy consumption can be obtained.

  According to a fourth aspect of the present invention, there is provided the switching chamber according to any one of the first to third aspects, wherein the storage chamber provided with the light source can be switched from a relatively low temperature to a relatively high temperature. It is what. The conventional switching room assumes that it can be used for multi-purpose purposes, such as refrigeration and freezing, and ice temperature, partial thawing, cooking function, etc., which are intermediate temperatures, and control temperature and humidity Has provided a wide variety of usage. However, as the number of switching operations increases, it becomes difficult for the user to determine the food to be stored, and the set temperature may be erroneously determined.

  In the invention described in this claim, by providing a light source in the switching chamber and switching the color tone of the light emitted from the light source for each set temperature, the temperature range set by the color tone of the light is what is the temperature In addition, since it is possible to make the user recognize what kind of food is suitable for storing the temperature range, it is possible to provide a refrigerator having a convenient switching room.

  The invention according to claim 5 is the invention according to claim 4, wherein the switching chamber provided with the light source is located below the refrigerator compartment and above the vegetable compartment and the freezer compartment. By adopting such a layout, it is possible for a woman of average height to open and close the door of the switching room without bending down, and to take in and out food in an easy posture without bending down. Therefore, the usability of the switching room is improved. In addition, in the vegetable room where the frequency of use is high, women with an average height can open and close the door without bowing down, and the heavy vegetables can be taken in and out without being cramped. There is no loss of usability. Such a layout that can be used in an easy posture can reduce the physical burden on the user.

  The invention according to claim 6 is the invention according to any one of claims 1 to 5, wherein the machine room is provided at the uppermost part of the refrigerator main body. The machine room 12 that houses the main components of the refrigeration cycle, such as a compressor and a condenser, is conventionally located at the back of the bottom of the refrigerator body, and thus reduces the volume of the storage room at the bottom of the refrigerator body. I was letting.

  Therefore, by arranging the compressor on the back of the uppermost part of the refrigerator body that was not effectively used in the conventional refrigerator cabinet, the conventional compressor part can be used as a refrigeration / freezing space, The effective internal volume can be increased without increasing the external dimensions.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows a longitudinal sectional view of a refrigerator in Embodiment 1 of the present invention.

  In FIG. 1, a refrigerator main body 1 is a heat insulating material formed by injecting a foam heat insulator 24 into a space formed by an inner box 22 in which a resin body such as ABS is vacuum-formed and an outer box 23 using a metal material such as a pre-coated steel plate. Has walls. For example, rigid urethane foam, phenol foam, styrene foam or the like is used as the foam insulation 24. Use of hydrocarbon-based cyclopentane as the foaming material is better from the viewpoint of preventing global warming.

  Further, a vacuum heat insulating material 25 is adhered and adhered to the space formed by the inner box 22 and the outer box 23 before foaming using an adhesive member (not shown) on the outer box side. In addition, the vacuum heat insulating material 25 is required to have a thin planar shape in order to be disposed within the thickness of the refrigerator body 1. Further, an adhesive member such as hot melt is applied to the entire surface of the vacuum heat insulating material 25 so that air does not enter the bonded portion. The vacuum heat insulating material 25 is foamed integrally with the foam heat insulating body 24 to constitute the refrigerator main body 1, and the performance is improved by the vacuum heat insulating material 25 having a heat insulating performance 5 to 20 times that of the foam heat insulating body 24. It is.

  The refrigerator main body 1 is divided into a plurality of heat-insulating sections, and has a configuration in which the upper part is a revolving door type and the lower part is a drawer type. From the top, there are a refrigerator room 2, a drawer type switching room 6 and an ice making room 5, a drawer type vegetable room 4 and a drawer type freezer room 3 arranged side by side. Each heat insulation section is provided with a heat insulation door via a gasket 31. From the top, they are the refrigerating room rotary door 7, the switching room drawer door 8, the ice making room drawer door 9, the vegetable room drawer door 10, and the freezer compartment drawer door 11.

  The refrigerating compartment rotary door 7 is provided with a door pocket 34 as a storage space, and a plurality of storage shelves 8 are provided in the warehouse. A storage case 35 is provided at the bottom of the refrigerator compartment 2.

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

  In addition, the storage case 35 is set at a relatively low temperature, for example, -3 to 1 ° C, for improving the freshness of meat fish, processed meat fish foods, dairy products and the like. 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 setting, and can be set to a predetermined temperature from the freezer compartment temperature zone to the refrigeration and vegetable compartment temperature zone, and the switch 12 on the refrigerating compartment rotary door 7 is operated. Thus, the temperature in the switching chamber is adjusted, and the temperature in the switching chamber 6 is detected by the detection means 17. The ice making chamber 5 is an independent ice storage chamber, and includes 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 normally 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.

  The refrigerator main body 1 is provided with a machine room 12 in which the rear part of the top surface is recessed. A second machine room 36 is provided on the lower 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. A pipe for installing and preventing drip-proofing may be combined.

  In addition, by using a flow path control means such as an electric three-way valve, a plurality of evaporators according to the partition configuration and temperature setting configuration are selectively used, a plurality of capillaries are switched, and gas is cut while the compressor 16 is stopped. 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 13 is installed on the top surface in the switching chamber 6 so as to illuminate the inside of the switching chamber 6 when it is turned on. When the drawer-type door is opened and closed, the light emitted from the light source 13 leaks, so that the user of the refrigerator can recognize the light. In addition, the light source 13 includes a plurality of light emitting sources, each of which emits light of a different color tone, and the light source is turned on and off through the control board 37. In addition, the light source 13 is provided with a cover 26 so that the light source 13 is not in direct contact with the food contained in the switching chamber 6.

  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 using 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 switching chamber 6 can be switched in several stages from the freezing temperature zone to the refrigeration temperature according to the purpose and preference of the user. In the present embodiment, the temperature compartment of the switching chamber 6 can be switched to a refrigeration temperature of 3 ° C., a freezing temperature of −18 ° C., a partial temperature of −3 ° C., a partial temperature of 3 ° C., and a chilled temperature of 0 ° C. When the person switches the temperature from the operation panel 14, the light source 13 is set so that light of the color tone set in advance for each temperature is emitted from the light source 13 step by step until the set temperature is reached. . Further, when the switching chamber 6 is opened, the light source 13 is covered with a cover 26 so that the light source does not directly enter the user's eyes.

  The cover 26 is subjected to, for example, glass cutting so that the light source 13 reaches the entire switching chamber 6. Thereby, even if there are few light sources, light can reach the entire switching chamber 6 and light can be uniformly applied to the entire food. Therefore, the number of the light sources 13 can be minimized, the installation space for the light sources can be narrowed, and the space for the switching chamber 6 can be widened. Further, when the light source 13 has a wavelength such as ultraviolet light that is said to affect the human body, even if the user opens the switching chamber 6, the user is directly irradiated by covering the light source 13 with the cover 26. It can be handled safely.

  Furthermore, by providing the cover 26 with a pupil disk that can change the incident angle of the light source 13 and convert the wavelength, even one type of light source can irradiate light sources of all wavelengths. Therefore, the number of the light sources 13 can be minimized, the installation space for the light sources can be narrowed, and the space for the switching chamber 6 can be widened.

  An LED element is used as the light emission source 13, and elements that emit light in the wavelength regions of red, green, and blue are installed on the same base, and the lighting can be switched to change colors up to seven colors by controlling their lighting. .

  Further, although the color setting of the light source 13 at each temperature is not particularly specified, the refrigeration temperature which is relatively high in the present embodiment uses green which gives a mild impression, and the refrigeration temperature which is relatively low. Used a blue color that gives a cold and cold impression. In addition, it is an intermediate temperature range generally called a new temperature range. For the partial temperature that mainly stores fresh food such as meat and fish, the purple color that gives a clean feeling and an intermediate impression is used to preserve dairy products and processed foods. White was used for the suitable chilled temperature.

  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 in the six switching chambers can be visually recognized, and the user can easily select the storage object from the color tone. Can be associated. Therefore, when food is stored in the switching chamber 6, storage of food suitable for the set temperature can be promoted while preventing user confusion.

  In addition, depending on the image of the color tone, the user can feel a clean feeling and a favorable impression that the cooling room 6 is effectively cooled, and increase the user's satisfaction with the refrigerator. Can do.

  In addition, although it does not specifically limit about the wavelength of light, When the light source 13 which radiates | emits the light containing ultraviolet light is used, the microorganisms which ultraviolet light floats in the storage chamber or adheres to the wall surface or food surface It is possible to inactivate the growth function of microorganisms. 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.

  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.

  The light source 13 may be a light bulb, a light emitting diode, a fluorescent lamp, an ultraviolet lamp, or the like, but is not particularly specified, and any light source 13 is applicable. Among them, the light emitting diode hardly generates heat by the lamp itself, is excellent in running cost and durability, and has high versatility.

  Moreover, the installation of the plurality of light sources 13 in the same storage chamber is not limited to one place, and the individual light sources 13 may be installed in different places in the same storage chamber.

  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 6. 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.

  By switching the color tone emitted from the light source 13 to a specific color when the temperature in the storage room rises, the user can recognize the long-term opening of the door, and the quality of food or ice in the storage room can be protected. In addition, since it is possible to prevent an increase in power consumption for temperature recovery after the door is opened for a long time, an effect of reducing the amount of energy consumption can be obtained.

  The color of the light source 13 that allows the user to recognize the temperature rise in the storage room is not particularly specified. However, in terms of color engineering, the red system gives attention, warning, and a dangerous impression, and many users It is preferable because it is a color that is clearly recognizable by the eyes.

  Further, when the color of the light source 13 is a yellow system, it is easy to be recognized because it is a conspicuous color, and since yellow can be recognized as the same color by both a normal person and a color blind person, both are used in the same way. Therefore, it is possible to provide a refrigerator that is easy to use.

  Moreover, such input of the light source 13 is performed by the reaction of the detection means 17. The detection unit 17 uses a temperature sensor and inputs after detection of a certain temperature. For example, when the detection unit 17 is a door switch, the input is performed after a certain period of time after detecting the door opening. It is not particularly specified.

  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 door of each storage room is of a rotary type for the refrigerator compartment and a drawer type for the others in consideration of usability, but these are not particularly limited.

  As described above, in the switching room 6 of the refrigerator according to the present embodiment, the color tone of the light emitted from the light source 13 reminds the user of the food to be stored under the set temperature and recognizes the set temperature situation. Therefore, it is possible to provide a refrigerator that is easy to use.

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

  In FIG. 2, the light source 13 is installed in the switching chamber 6, and the machine room 12 that houses the main components of the refrigeration cycle such as the compressor 16 and a condenser (not shown) is the back of the uppermost stage of the refrigerator room 2. Is installed.

  Conventionally, the machine room 12 is located on the back surface of the freezer room 3 which is the lowermost part of the refrigerator body 1, and thus the volume of the freezer room 3 is reduced. However, the machine room 12 is effectively used in a conventional refrigerator cabinet. Since the conventional machine room 12 can be used as a refrigerating space by arranging it on the back of the uppermost part of the refrigerating room 2 which has not been used, the freezer room 3 can be effectively used without increasing the external dimensions. The internal volume can be increased.

  Conventionally, in order to compensate for the shortage of the capacity of the freezer compartment 3 at the lowermost part of the refrigerator body 1, the switching room 6 is frequently used as the freezing mode. It is possible to promote the use of the food at a temperature other than the freezing temperature, and the food can be stored at a wider temperature range for the user. As a result, the multipurpose use according to the situation which is the merit of the switching room 6 can be promoted, and the function of notifying the user of the temperature switching by light can be used effectively.

  As described above, the refrigerator according to the present invention can promote the recognition of the temperature in the storage room and the storage object suitable for each storage room using the light source, and improves the usability of the refrigerator. Therefore, the present invention can be applied not only to cold insulation but also to devices intended to keep warm, and can be used for improving usability of, for example, a showcase, a cooler box, a heat insulation cooler, and a heat insulator.
