Description

1299395 'Nine, invention description: [Technical field to which the invention belongs]

The invention relates to a preservation technology of foods such as fruit thinning in the φ phase I phase of the refrigerator. [Prior Art] Previously, the refrigerator is known as a technology for improving the storage property of fruits and vegetables by illuminating fruits and vegetables with red led from above. For example, 彖昭 Patent Document 1). In addition, there is also a setting of white glory a 兀 且 and the switch for detecting the opening and closing of the window is used to perform the light-on control to reduce the green chlorophyll reduction (for example, moxibustion patent document 2). In addition, there is also a report that, by illuminating the LED for the temperature of the unconcealed temperature of the food below 0 C, the respiration phenomenon is reported by you, Tara, and the action or low temperature barrier (for example, Patent Document 3). J., [Patent Document 1] Japanese Special Openings 2_2673, 1st, 2nd, etc.) % c 0036 [Patent Document 2] 曰本特开平 9_28363号1, etc.) Uub Bar, [Patent Document 1] Japanese special 帛 2 () (n_61459 0012 ban, 0069 ban, etc.) U11 block, [Summary of the invention] [Problems to be solved by the invention] Previously, the refrigerator had (1) the light used red LED, so the appearance was poor; (7), Measure the opening and closing time of the window and control the opening time of the window, and all the windows to open and close the mechanism; (3.) from the food in the storage container arranged in the lower part; (4) because it is illuminated from above:

7042-7134-PF 1299395 Wiring of electric milk parts is difficult; and (5) When it is illuminated from above, it is only illuminated when the window is closed. Therefore, it is difficult to confirm whether there is a problem such as turning on the light in the home or in the store. In the case of household refrigerators, there are many types of fruits and vegetables to be preserved, or many types of foods such as fruits and vegetables are often replaced, and if they are not placed, they are placed in the refrigerator, or placed in the refrigerator. There are various preservation modes such as space, period and state. Moreover, it is also possible to store only the refrigeration and freezing, and to store it regardless of the temperature. For the work required and necessary in such food preservation, no matter what kind of preservation, there is a preservation effect by irradiation of light, and there is no adverse effect. In the refrigerator with low power consumption and good efficiency, the life of the parts Reporter j almost no maintenance, but in the case of white fluorescent lamps, good influence and adverse effects cannot be separated. In the specific preservation effect such as red or blue, even if a good wavelength is selected, the experiment is performed under ideal conditions. It also has a poor storage condition, so it may not be possible to obtain a practical refrigerator. In order to solve the above problems, the present invention provides a refrigerator which is excellent in appearance and appearance of foods such as fruits and vegetables, and which can effectively store foods in various storage forms. Further, the present invention is a refrigerator which has a long service life and is efficient because of the effective use of a small number of semiconductor light-emitting elements (LEDs). Further, the present invention provides a refrigerator which is capable of irradiating light even when stored in a necessary space such as a storage container provided at a lower portion, and has good storage stability. Further, the present invention provides a refrigerator which is easy to maintain and which can be assembled at a low cost with a small amount of ineffective energy consumption and which is easy to recycle. Further, the present invention provides a refrigerator which uses light which is not adversely affected by food and is friendly to 7042-7134-PF 6 1299395 which is also used for illumination in an ice storage, and which not only improves food preservability but also improves food preservation performance. [Means for Solving the Problem] The refrigerator of the present invention has a plurality of light sources that illuminate light having a warm wavelength, and a control device that individually controls the light sources to be turned on. i, the present invention is a storage container for storing foods in a "prepared", shame-like, and non-illuminated space. [Invention Effect] • Inventing a refrigerator, the light source is irradiated with light having a wavelength of warmth, so that it does not damage The appearance of foods such as fruits and vegetables can increase the nutrient content, and has the effect of being able to use the light in the ice storage. Moreover, the light source of the refrigerator of the present invention, the LED is intermittently irradiated, and the control allows the UDs to be turned on and off, which can be extended. [Embodiment] Embodiment 1 FIG. 1 is a cross-sectional view showing a refrigerator compartment according to an embodiment of the present invention, and FIG. 2 is a view showing a room interior of a fruit and vegetable according to Embodiment 1 of the present invention. 3 is a perspective view of a wavelength characteristic of an LED as a semiconductor light-emitting element; and FIG. 4 is a perspective view showing a light-emitting device according to Embodiment 1 of the present invention. In Fig. 1, a 1 type refrigerator body is used in the refrigerator. The upper part has a refrigerating compartment 1 具备 with a switch door, and can be switched from the freezing temperature zone (-18 ° C) to refrigerated, fruit and vegetable, chilled, and weakly cold under the refrigerator compartment 1 〇〇 a temperature zone such as a bundle (-7C), which has a switching chamber 4拉 pulled out of the door, and an ice making compartment 5具备 with a pull-out door arranged in parallel to the 400, arranged at the lowermost portion, and 7042-7134-PF 7 1299395 Pull out the cold of the sputum; Dong t, and the vegetable and fruit room 300 with the pull-out door between the room (4) and the ice-making room. Above the window of the refrigerating room, the temperature or setting of each room is adjusted. The operation panel 5 and the operation panel 5 including the liquid crystals and the like for displaying the temperature of each chamber at this time are provided with a storage container 3 made of an opaque material in the vegetable compartment 300 as shown in Fig. 2 and Fig. 2 . 3. The first part of the storage container 30 is made of a light-transmitting material, and the inner valley 31 is filled with food such as fruit thinning. The opaque material is made of white plastic or stainless steel or aluminum. As shown in Fig. 2, the 32-type illumination device is provided on the back surface of the second storage container 31, and is capable of illuminating light around the center of the second storage container 31. The illumination device 32 is as shown in Fig. 3, A substrate mounted with four LEDs 34 emitting a wavelength range of 550 nm to 620 nm with a peak of 590 nm In the first drawing, a 1 〇-based compressor, an 11-series cooler, and a 12-system fan that blows cold air cooled by the cooler 11 into the refrigerating compartment 100 and the freezing compartment 5 〇 0 The bunker unit of the cold air chamber 5 〇〇, the 14 series is used to introduce the cold air cooled by the cooler into the air passage in the refrigerating chamber 1 . Lu control, 3⁄4 optical device 3 2 switch lamp control device The substrate 2 2 is housed in the electrical component chamber 21 on the back side of the refrigerator, and is controlled by a microcomputer or the like mounted on the substrate 22. In the fourth diagram, the illumination device 32 is mounted on the mounting substrate 33 as a light source. The semiconductor light-emitting element LED 34 and the light-transmitting cover 35 for protecting the LED 34 are formed. In general, the directivity of the LED is narrower as the brightness is higher. Therefore, the mounting substrate 33 and the lid 35 are fixed by screws so that the irradiation angle is not changed by the vibration of the refrigerator. Mounting substrate 7042-7134-PF 8 1299395 33 The inner surface of the substrate is covered with a sealing weave 36 in order to prevent short circuits. Further, the illuminating device 32 is incorporated in the deep-side heat insulating portion 37 of the vegetable and fruit chamber 300, and the light is provided to illuminate the inside of the vegetable and fruit chamber 3, but in order to prevent the inside of the lid 35 from being exposed The 0-ring 38 is inserted to increase the degree of adhesion to block the cold air, prevent the dew junction of the mounting substrate 33, or the scattered light due to water droplets. Further, the lid body 35 has a projection portion 39, and the storage container is formed to prevent the shape of the surface from colliding with the cover body to prevent the light from being scattered and reflected by the wear of the surface of the cover body. early. The collision prevention of the surface of the carcass is expected to be performed in the process of manufacturing the cover 35 and the storage container during use, and the projections 39 are provided, and the illumination device is placed in the refrigerator as a vegetable and fruit room. The deep side, especially on the back side, is close to the fan or the support plate and other electrical parts. Therefore, the wiring is easy to report and can be produced at low cost. Moreover, when the cold air is circulated in the refrigerator, the air outlet and the suction port are disposed at the deep side, so that the direction of the light from the deep side toward the front side and the direction of the flow of the cold air in the refrigerator, that is, y owes cold air or sucks in air-conditioning. The direction is consistent. A refrigerating compartment without a storage container, or a vegetable and fruit compartment having a storage container, etc., in a refrigerator, even if a lot of food is squeezed, there is a lot of structure in which cold air is easily circulated, and by aligning with the cold discharge or suction direction, Light rays are easily passed through the whole. Further, by arranging the illumination inside the refrigerator on the deep side, the inside of the refrigerator can be easily seen when the door is opened.

In addition, it is better to set the light on the top or the side than the user. Therefore, it is easier to confirm the opening of the product in the store or in the home 7042-7134-PF 9 1299395. Further, the heat insulating material structure on the back side is stronger than the partition plate separating the chambers, and the vibration applied to the LEDs is reduced, whereby the reliability is improved. Figure 5 is a graph showing the wavelength of visible light absorption and its color. Figure 6 shows the growth effect of plants per unit of energy, expressed in terms of wavelength. The LED 34 emits an object having a wavelength in the visible light region. In the visible light, as shown in Fig. 5, the shortest wavelength to the longest wavelength are respectively purple, blue, green, yellow, orange, and red. Plants are basically used for photosynthesis to grow, but in addition to this, the light forms of plant matter changes such as seed germination, flower bud differentiation, flowering, cotyledon development, chlorophyll synthesis, and inter-strength elongation are performed. The accumulated nutrients serve as an energy source. Among them, germination or flowering is not suitable for the formation of light forms for preservation of fruits and vegetables. As shown in Fig. 6, it is promoted by blue light near 47 〇 nm and red light near 660 mn. In addition, the absorption peak of chlorophyll is also blue and red, and the ratio of green to yellow is small. In addition, as shown in Fig. 6, the energy efficiency of photosynthesis is highest in red light, and the shorter the wavelength, the lower the energy efficiency. Therefore, in the visible light field, the light with the most effective photosynthetic speed is red, the second is blue, the second is blue, and the other colors are more effective. {, the wavelength near the blue light will promote germination and flowering, so it is not suitable for long-term preservation of fruits and vegetables. Next, the photosynthesis reaction will be described. When the photosynthesis reaction is expressed by the chemical formula, 6CO2+12H2〇 + 688kcal C6Hi2〇6 + 6h2〇 + 6〇2 (c〇2··CO 2 'h2〇: water, 688kcal: light energy, C6Hi2〇6: glucose)

7042-7134-PF 10 1-299395 This reaction is divided into a dark reaction using light energy and a dark reaction not using light energy. The bright reaction system converts solar energy into chemical energy. In this stage, carbon dioxide is not used, and pigments such as chlorophyll use light energy to dissolve water into oxygen and hydrogen, and accumulate chemical energy by the action of enzyme proteins. Further, in the dark reaction, glucose is synthesized using hydrogen generated by the reaction and carbon dioxide in the atmosphere. In addition, the storage of fruits and vegetables that increase glucose may become better, or may be converted from glucose to vitamin C. Thereby, by using a plurality of LEDs to suppress heat generation, water dispersion of fruits and vegetables φ and the like can be suppressed, and LED 34 can be used as a red LED to promote photosynthesis. However, the cool color of fruits and vegetables does not look bright under red light, and it is impossible to judge the deterioration of fruits and vegetables. The red light has a warning impression that it is not suitable for lighting in the refrigerator. Therefore, yellow light near the peak of 590 nm or near 6 〇〇 is used. Orange light and other warm-colored light LEDs, instead of red or cold-colored light LEDs that make fruits and vegetables look like fresh, can get close to the effect of white heat, and can achieve photosynthesis and illumination at the same time. Moreover, as shown in Fig. 6, photosynthesis can achieve food preservation effects. As shown in Fig. 5, when the wavelength range of 580 to 61 〇 nm from the yellow color to the orange color is taken as a peak, the color of the warm color can be obtained. Further, an illuminating device comprising a plurality of LEDs combining a red LED and a blue LED is formed, whereby light illuminating the peak of chlorophyll absorption is irradiated: more effective and fine photosynthesis. That is, the plurality of colors are simultaneously illuminated to obtain warm light, and at the same time, individual effects can be obtained by individually emitting light. Moreover, not only the monochromatic light-emitting LEDs but also the LEDs and the phosphors can be combined.

And by using high-brightness LEDs or diffused LEDs, LEDs can be reduced

7042-7134-PP 11 1299395 numbers, while achieving photosynthesis effects and illumination, can also constitute a low cost illumination device 32. Further, Fig. 7 is a circuit diagram of the illumination device, and Fig. 8 is a diagram showing the mounting arrangement of the LEDs 34. The system 34A of the two LEDs 34a and 34b of the parallel mounting substrate and the system 34B of the parallel LEDs 34c and 34d are arranged in parallel. The currents of about 30 mA are applied to DC 5V to 12V, whereby the LEDs 34a, 34b, 34c, and 34d are caused to emit light. A small current with a current value of 30 mA is safer. In addition, '34A and 34B, the LEDs are composed of two systems. ・ As shown in Fig. 8, the systems are arranged up and down, and the switch lights are controlled by the microcomputer, respectively, so that when only the system is turned on, There are about lOOLx in the illumination range. When the 2 system is turned on, it can ensure the illumination of about 3〇〇Lx, which can extend the service life of the LED. Therefore, it is not necessary to detect the opening and closing of the window to ensure the full use of the life. Further, by making the plurality of LEDs a system, that is, by group control, the number of connections of the microcomputer can be reduced, and the effect of simplifying the substrate can be achieved. As shown in Fig. 7, the electric crystal that controls the switching lamp from the microcomputer output signal and the resistor that sets the current into the LED current and the current limiting are connected to the LED string to control the switching light of the LED. In the mounting of the substrate having the above-described configuration, when the resistor is placed on the side of the control board, the substrate 33 of the illumination device 32 can be miniaturized, and it can be easily placed in the vegetable compartment, and the resistance heating can be suppressed. Therefore, the storage performance of the fruit and the fruit can be improved. Further, when the resistor-arranged illumination device 32 is mounted on the side of the substrate 33, it is easy to confirm the effect of turning on the light or finding a defective place in the event of a failure or the like. Further, although the control of the switch lamp has been described as a combination of two or four, it may be a combination of a small number and a plurality of eight or twelve combinations. Also, as long as the number of LEDs or the necessary illumination is used

7042-7134-PF 12 1299395 It is sufficient to select the applied voltage/current. By promoting the synthesis of glucose and other fruits and vegetables, and improving the storage of fruits and vegetables, and increasing the vitamin C nutrition, it is necessary to make the dark reaction of photosynthesis. Therefore, it is not necessary to open the LEDs 45 frequently. It is necessary to limit the opening. Light time or illumination. By this limitation, the life of (10) can be extended without the need to replace the illumination device. By this, you don't need (four) energy to save food. In the refrigerator configured as above, the operation will be described below. The cold air cooled by the cold pack in Fig. 1 is sent to the inside of the refrigerator by the fan 丨 2, and the freezer compartment 2 is cooled to a predetermined temperature. In addition, the cold air cooled by the cooling n 11 is partially controlled by the air passage 14 and the opening and closing of the reading plate η, and is sent to the refrigerating compartment 1〇〇, the switching chamber 4〇〇, and the ice making compartment 5〇〇, and the refrigerating compartment 100 The system is cooled to a predetermined limit, the switching chamber is cooled to a corresponding set temperature, and the ice making chamber 500 is cooled to _18. In order to prevent the loss of fruit and vegetable water, the vegetable and fruit room 30 does not directly blow into the air-conditioning. (4) From the upper part of the vegetable and fruit 2 switching room 400 and the ice-making room 500, the lower part of the vegetable and fruit room 300 is cooled to 200 radiant cooling, and indirectly cooled to the established The temperature is about. The field j may not be indirectly cooled as described above, and it is also possible to make a structure for circulating cold air. ^

As shown in Fig. 2, there are storage containers 3〇 and 2nd storage of cereals 31 in the vegetable and fruit room. When the fruits and vegetables are stored in the vegetable and fruit room, the rapeseed and coagulation that mainly require photosynthesis effect (4) In the second collection (four) n 31, the roots and stems such as horseradish and onion are stored in the storage container. The fruits and vegetables accommodated in the second storage container 31 are illuminated by the illumination device 32 provided on the back surface of the second storage container 7042-7134^PF 13 1299395. This day, when using the high-brightness LED34, it can illuminate about 300~400Lx. When the ϋ2 is used, it can illuminate about 〇~】5〇Lx. Further, the roots and stems accommodated in the storage container 30 are blocked by the opaque material, or the food stored in the second storage container 30 is blocked from direct light. Figure 9 is a simple control flow chart of the illuminating device. The ι〇 diagram shows the timing chart of photosynthesis and fruit and vegetable photosynthesis. In Fig. 9, the main body of the refrigerator] after the power is turned on, the data stored in the control board microcomputer is controlled by step 4, and when the data is turned on by 2, in step 41, the LED 34 of the two illuminations 32 is turned on. When the foregoing data is turned off, in step (4), the LED 34 of the device 32 does not turn on the light. Then, when the refrigerator enters the defrosting in step 43, in step 44, the four LEDs 34 are redundant, and in step 45, after the four 丨Friq/i, the process proceeds to step 46, and the fourth (four) The data of the substrate is continued for 3 small connections, and the 2 LEDs are turned on or off. Step 4 6 Qiao ## ★, μ / 诹讪 system 5 has recalled the state before the defrosting in step 43 is the same as the case. Step 43 Two, in addition to the phase action, is controlled once a day, so the 'hunting step by step 4 3 to step 以上 β above... one series of control, so that 3 〇〇 Lx above the light for 3 hours. In Figure 10, four (10) lights up, and the illumination and fruit action are triggered. After the implementation of the hour, the two LEDs light up, and the first cooperation is to use the Ming reaction, after 3 # 夕, children or switch to off. The lamp, thereby producing a dark reaction to photosynthesis. In the refrigerator, except for the private circulation, the water contained in the air-conditioning is used to cool the cold air in the ice storage.

Kf± U. ^ The knife is fixed on the fan of the cooler 11 as the evaporator. The removal of this frost is called defrosting. Evaporation in the refrigeration cycle

7042-7134-PF 14 1299395 The air inside the recirculating machine 10 cycles of evaporation of air in the n, at this time, included in the = cooling the ice cubes to become frost. In order to defrost, actuate the p-heater to remove the frost. At this time, DD σ σ .. Λ . The fan in the ice bank 12 2, close the raft to prevent the cold air from blowing into the chambers, the cold air is crying, the s rolling is blocked, by heating Wide, no leakage, the temperature inside the ice store will rise. In the low temperature chamber below 二, the higher the temperature, the more active the photosynthesis is. Therefore, it is very effective to increase the illumination intensity of the light source in the ice storage during defrosting. In addition, the defrosting movement #, the memory... The opening and closing mode of the refrigerator door is separated by the real time when the refrigerator door is opened and closed, so that the light source can be irradiated according to the preset conditions. Moreover, in the freezer compartment, not only the illumination inside the ice store, but also the ultraviolet rays are also effective. Further, although the defrosting operation has been described with reference to the control of the light, it is of course possible to memorize the opening and closing of the portal to set the time, or to set the late-night time zone in advance, and only to turn on the light during this time, and the other is outside. Do not turn on the light, or increase the illuminance, such as setting the time zone with the time zone outside the night time zone and setting the time base. The cycle of switching lights or the cycle of increasing the illuminance and reducing the illuminance does not need to be performed once a day, as long as it is necessary to increase the nutrition of the fruits and vegetables. Then, by operating the operation switch of the operation panel 5 provided in the window of the refrigerating compartment 100, the switching light of the LED can be switched. In step 49, the operation panel accepts the switch input. When the LED is lit, the display spot will light. When the LED is off, the display spot will be extinguished and the status data will be transmitted to the control board. In step 50, the control substrate receiving the signal corresponding to the data causes the LED 34 to illuminate • 2 or off. In the switching operation, by the switch light that can select the LED, 7042-7134-PF 15 1299395 users who do not need to save leafy vegetables can annihilate the led, or the leaves are not listed in the winter, can be operated by switching Destroy the LED. Further, the operation panel is not limited to being set outside the refrigerator, and may be installed in the library. It is also possible to operate the lighting in the refrigerator from the operation panel; and to transmit the command by means of a wired or wireless method such as a wire, etc. Control device. ^ ◊ , , , , , , 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者 使用者When you open the window and only use it as the light in the ice store, you can set it as “Ding Magic” and sigh von 2 lights. When you pay attention to energy saving, you can set it to turn off the light. X 'When the three-stage control of the point 4 light, the point 2 light, and the light off is set to be stronger than the temperature setting of the vegetable and fruit room/1?/weak, the temperature environment of the suitable leafy vegetables is set to "strong"; In the vegetable and fruit room, the lights are turned on continuously (9): those with the preservation effect are set to “medium”; the fruits and vegetables that have higher temperature settings and are not illuminated and energy-saving are set to “weak”, and the fruits and vegetables room can have the above three proposals. 'In particular, it is not necessary to set the illumination setting on the operation panel to simplify the operation panel interface. In addition, it is also possible to switch off the lED in conjunction with the "Energy Saving Mode" or "Power Saving Mode" that can be set on the operation panel. Finally, in step 53, because the plug is unplugged or powered off, etc., and the power of the refrigerator 1 itself is reset, the state of the time is memorized, and when the power is turned on again, the process returns to step 40, so that it can be reset from the power source. The state before it begins. Above, although it has been explained that there are 2 lights, 4 lights, and lights off, you can also increase or decrease (10) one by one, or turn 3 or 4 LEDs into a group to turn the lights on and off.

7042-7134-PF 16 1299395 In the case of weak illumination, it is also possible to continuously illuminate regardless of whether the window is opened or closed, and the necessary illumination can be performed for the purpose. ~ Control by the above - When the four LEDs are lit, the photosynthesis effect can be obtained, and the dark reaction effect of photosynthesis can be obtained when two LEDs are lit. ^Multiple LEDs are alternately lit, which can extend the service life of the LED. It is not necessary to replace the illumination device before the end of the life of the refrigerator. Moreover, because the clothing is placed on the back, it can improve the airtightness to prevent the condensation. ^ , can: stop the user inadvertently touching, can also prevent the failure and transfer security. Moreover, the timing of the illumination does not have to be implemented when the window is closed. By implementing the above control, it is not necessary to measure the window switch and turn on the light for a long time. Therefore, it is not necessary to use the touch-measuring window switch to touch the cutting part. The system itself can also save energy. Of course, it is also possible to switch the switch light or the illumination level from the opening and closing signal of the dry grip window by the setting of the microcomputer. In addition, relative to the rated value, the current value is increased to read the WOLx with less f-flow value, and the moon is also guaranteed to be about 3 〇〇 Lx to control the illuminance. In addition, when the brightness of the LED34 is reduced due to the use of the ' and T' gates, the number of LEDs that can be lit can be controlled to ensure illumination. The system does not use the radiant-cooled vegetable and fruit room, and blows it like other ice rooms: In the cold room, 'when the water is generated during defrosting, it is blown into the fruit and vegetable room. 'It can be promoted more, and the gas circulation is completely independent of the light source illumination system. That is, the cold air circulation system is detected by the temperature in the ice storage tank, corresponding to the fan movement, and necessary (4) β I (4) board people into the air. In addition, in accordance with photosynthesis, the illuminating system is used to make the sturdy, sinuous, and sinister

7042-7134-PF 17 1299395 Source. Further, in the vegetable and fruit room, etc., the rolling cycle enters the storage container to be fixed or the upper part, but the amount of cold air circulating in the direction of R σσ is small. Hunting is carried out by a small number of air-conditioning cycles, which can provide carbon dioxide in the ice bank. The photosynthetic dark reaction can be effectively implemented. The U map of the stomach is a comparison of the glucose and vitamin C changes in the rapeseed for 3 days, and the comparison between the illuminance and the comparison of the illuminance and the 昭L + τ... shot in 1 day. The amount of each component in each condition is expressed as a percentage after 3 days of not storing the rapeseed (unirradiated), and the amount of each component under each condition is expressed as a percentage. That is, the line of 1% in the chart. The amount of each component in the green watch is not changed after 3 days, and it is not changed when it is not irradiated. The result is that the 60 system makes the light of about 260Lx 1 day and the shot is 3 hours. The amount of each ingredient in the rapeseed is 9 compared with that of the non-irradiated Γ <,, σ fruit, more than the original sugar and vitamins are more than the irradiator. And the results of the 61 series irradiation about igg Lx light experimental results' effect Low-lower ## When the heart is formed, it can be used as the light in the ice store. In the darkroom, it can identify the type or label of the preserved food, for example, to identify the bottle of beverage or seasoning or vegetable or fruit. Therefore, in order to produce photosynthesis Ming reaction, so that about 30OLxl days Zhao shot qf + ..., shooting 3 hours is enough, leaving 21 small 'Less Shu Ming reaction 1⑽

Below Lx or turn off the light to produce a dark reaction. The result of the test is the result of the figure i 2 . Figure 12 is a cross-sectional view of another vegetable and vegetable chamber perspective view of the present invention. In the second drawing, the storage container 30 is made of an opaque material, and the second storage container 31 is made of a light-transmitting material. However, as shown in Fig. 12, the second storage container 31 is made of an opaque material. The light-emitting device 32 of the self-standing back surface is only made of a light-transmitting material, and

7042-7134-PF 18 1299395 Set the light transmission window 40. At this time, the storage container 3 constitutes a light material or an opaque material. In order to achieve the above-described configuration, the light that has been irradiated into the second storage container 31 for storing the leafy vegetables is reflected by the irradiation inside the container, and the light beam of the LED is irradiated onto the vegetable without loss, and is irradiated to the storage container 3 The occlusion of the light of the food of 〇 is also better. χ When the unevenness is provided on the surface of the second storage container, the light is scattered or scattered in the container, so that even in the case of the directional (four) LED, the photosynthesis can be promoted in a wide range. Fig. 14 and Fig. 15 are sectional views of the interior of another fruit and vegetable for carrying out the invention. In the second drawing, the storage container 3 is made of an opaque material, and the second storage container 31 is made of a light-transmitting material. However, as in the case of (10), the second storage container 31 can be made opaque. The material is made to make the container 3. The light-transmitting material is made to illuminate the container 3 by tilting the illumination device 32 or the mounting substrate. The light of the inside of the 'second storage container' is blocked. By adopting the above configuration, the leafy vegetables having a large umbrella portion are generally stored in the lower storage container 30, and many small objects are reported and are not suitable for the roots of the light. In the upper second storage container 31', the finishing property is improved. In the second drawing, the same effect can be obtained by using only the light-transmitting portion or the transparent effect from 4G. In this case, it is surrounded by the reflective material in an all-round manner, so that the illumination effect can be increased. The first figure is a perspective view of the interior of the vegetable and fruit interior for implementing the present invention. In the figure 2 of the drawing, the illumination device (10) is attached to Second storage

7042-7134-PF 19 1299395 The plane of the container 31, as in the case of the 〗β闰 - 戈迪i b diagram, can also be placed on the side. Or, set it on the deep side of the upper part of the vegetable 胄 _, and, tilt the light-emitting device 32, or illuminate the direction of the LED, so that the light can reach the container μ. The hunter is reflected by the surface of the container, or on the surface of the container. The reflections generated by the set bumps will report an effective reflection or scattering in the container. By adopting the above configuration, the light emitted from the side or the deep side of the upper surface is reflected to the side composed of the plastic material, and the light is irradiated without waste, and the fruits and vegetables are preserved for ten years. The storage container also has a good effect. Even when the window is opened, the light does not escape to the outside, so that the function of the light in the ice store can be effectively utilized, and the lock effect of the store surface can be improved. In Fig. 16, although the light source is provided at the center portion of the side surface and the depth, it is better to reflect the interior of the ice bin or the photosynthesis at a position deeper than the center portion. Figure 17 is an external view of the refrigerator of another configuration; Figure 18 is a sectional view of the fruits and vegetables. In the figure 7 of the present invention, the main body of the refrigerator is an ice making chamber having a two-door refrigerator in the uppermost portion of the refrigerator, and an ice making chamber having a door open and closed under the refrigerator compartment 100. There is a freezing compartment 200 for opening and closing the door below the ice making compartment 5, and a vegetable and fruit compartment 3配置 which is disposed in the ice making compartment 5〇〇 and the freezer compartment 2〇〇 and has a door for opening and closing. As shown in Fig. 18, in the vegetable and vegetable compartment 300 of the vertically long design, a drawer-type storage container is arranged from the top to the bottom, and is suitable for small fruit or tomato size 31a, 3 lb, 31c for medium-sized fruits and vegetables such as leafy vegetables, and Suitable for preservation of bottles or large vegetables for 31 days. The elements 32a, 32b, and 32c are respectively irradiated to the storage unit by the illumination device.

7042-7134-PF 20 1299395 By adopting the above configuration, the same effect as the light source illumination described above can be obtained. Further, when only the element 32b is used, when the leafy vegetables are stored in the storage container 31c' so that the root vegetables which are not suitable for illumination are stored in the storage containers 3a, 3, the storage of various fruits and vegetables is performed. Further, when a plurality of illumination devices 3 2 are provided, an illumination device 32 composed of a yellow LED is provided, and an illumination device 32 composed of red light lED and an illumination device 32 composed of an ultraviolet LED are provided, and illumination devices having different colors are provided. The leafy vegetables suitable for photosynthesis are based on red light. It is hoped that the foods that inhibit the growth of bacteria are based on ultraviolet light, and the foods that hope the above two effects are preserved on the basis of yellow light. Even when such a plurality of illumination devices of different wavelengths are turned on for a long time, when the control contents described in the illuminance and the like are increased in combination, the illumination at the time of opening the door is possible and the visual sensation can be suppressed. Further, when the LEDs 34 in the single unit of the illumination device 32 are LEDs of a plurality of colors, for example, LEDs of different colors such as red or blue, the illumination device 32 can be used, and even if the illumination device alone can emit light of a plurality of wavelengths, the fruits and vegetables are It is possible to carry out various kinds of light form formation, and the light spring system gives a color which is warmer than the red color, so that the appearance of the product and the appearance of the preserved food are improved. The light source described above is such that a plurality of LED elements having a plurality of optical semiconductors are provided on the mounting substrate 33 to simplify the structure or wiring. However, the substrate may be provided with only one Led element at one site. One LED can be configured. That is to say, a component with a wavelength of about 60Onm is disposed on the deep side of the vegetable and fruit room, and the light of the long-time weak illumination can be used to illuminate and preserve the high nutritional value of fruits and vegetables, and can also be deep in the lower part of the refrigerator. At the side, set a wavelength of about 6〇〇nm 7042-7134-PF 21 1299395

The component continues to be in a dimming state for a long time. Further, the illuminance is weakly converted by controlling the applied voltage during the defrosting and after the defrosting, thereby increasing the irradiation at night and the like, and the effect of producing reducing sugar and increasing vitamins. Alternatively, it is also possible to arrange an i-violet-emitting LED on the inlet side and to provide a freezer compartment for storing a bottle of beverage that is fading by ultraviolet rays. In this case, the lighting is performed for a long time, or when the window is opened, the lighting is turned off when the window is closed, and the sterilization effect is obtained. In any case, ultraviolet rays or red light are not directly seen by the eyes when viewed from the window or are viewed in a single color and can be inspected by light having a warm feeling close to natural light when combined with other wavelength LEDs. In the library, the user of the refrigerator has no need to worry about it when looking at food or holding it, and has a strong sense of security. In the structure of the storage container, the light-shielding portion, the illumination portion, and the unlit portion of the light source are described. However, there is also a storage room in which the storage container is not provided, and for example, a shelf is provided to separate and store the food. In the structure of each of the racks as the accommodating portion, the structure of Fig. 2 or the drawings of Figs. 12 to 16 may be provided with, for example, a light blocking portion. For example, it is possible to make the material transparent or mesh-like in the rack or use an opaque member, ϋ:: wood illuminating window ′ or to make the rack a structure for scattering light. Further, in the configuration of the figure of FIG. 4, the illuminating device is immersed in the air passage 14 in the airway unit. However, as shown in Fig. 19, the air duct 14 may be disposed outside the air duct 14 The outer side of the heat insulating portion is fixed by a screw 39. = The above configuration can also be obtained with the above description. (4) The illumination device 32 is attached to the surface of the ice bank (four), and when it is replaced or removed,

7042-7134-PF 22 1299395 It must be disassembled to the air path 14 for easy replacement, and it is easy to separate from the insulation of the insulation, and the recovery of the insulation material is simple. The illuminating device 32 of the present invention is provided in the vegetable compartment 3, but may be provided in the refrigerating compartment 100, the freezing compartment 2, the ice making compartment 4, or the switching compartment 500. Recently, the reason why the capacity of the vegetable and fruit room is insufficient or the temperature of the vegetable and fruit room is lower is that the fruit is stored in the refrigerator. Therefore, the same effect can be obtained. Moreover, regardless of the room, it is used as the light in the ice store, and when it is used intermittently and only for a short time, even LEDs of about 6 〇〇 nm wavelength, for example, LEDs such as ultraviolet rays are used alone. In any ice room, tea or juice in bottled or pudding bottles does not affect color, and has a bactericidal effect on ice or preserved food. Mushrooms have the effect of increasing vitamin D. The present invention is mainly provided with a storage container for storing fruits and vegetables in one of the vegetable and fruit compartments, and an illumination unit is disposed on the back surface of the storage container. It is also possible to have a light-shielding portion in the storage valley, and to have an illumination area and an unilluminated area. Further, according to the present invention, the light source having the illumination unit is a semiconductor light-emitting element that outputs a wavelength in the visible light region having a peak wavelength of about 600 nm. Therefore, the food is not poorly visualized. Moreover, the present invention has a plurality of LEDs for illuminating the light source, so that the LEDs can be turned on or off for a certain period of time, or the LEDs can be redundant or extinguished between the 疋τ, respectively, and the control is not controlled during the operation of the refrigerator. All led are extinguished at the same time, or, after several years of use, when the brightness of the lED monomer is lowered

7042-7134-PF 23 1299395

When the number of LEDs that are lit at the same time is increased, it is very effective. Further, the LED is divided into a plurality of LEDs, and the structure can be simplified by using n. 0 group control LEDs. In the present invention, by controlling the number of LEDs to be lit, f is irradiated with high illumination for several hours, and the Tianren ^W is weakly photographed by Tang Zhao, which can improve preservation. And the effect of energy saving. Moreover, the present invention operates the refrigerator by operating the panel on the door of the refrigerator or the remote controller, the operation panel in the ice phase, or the operation via the communication ^, / Dingle. Can stop the illumination function, or set the illumination. The temperature of the door object ice storage unit is further set. The present invention is a special time zone such as a few hours after defrosting or the like, and the illuminance of the south is illuminated, whereby the food preservation performance can be further improved. Moreover, the refrigerator of the present invention has an illumination device with a wavelength of light of about 590 to 600 nm from the back surface, a light-shielding portion for limiting the irradiation field, and lighting control. Therefore, the light has a warmth and can be used as an interior of the ice storage. . In addition, it is placed on the back of the storage container, or it is placed so that it is inclined from the side or the top side. Therefore, the I line can illuminate the whole, and the visual perception of fruits and vegetables can be impaired, and nutrients can be increased. Further, in the illuminating device of the refrigerator of the present invention, the LEDs are intermittently irradiated or a plurality of controls are provided, and (4) are alternately lit, whereby the life of the LED can be prolonged.

Get sterilization and other effects. The above description has been controlled to make this multiple light two 7042-7134-PF 24 1299395

The poles are individually or divided into an array and connected in parallel to each other. By setting a non-lighting person and a lighter, energy can be saved, and the life of the device can be long without changing the device, and an efficient device that does not waste energy can be obtained. Next, another control circuit configuration and operation will be described below with reference to Fig. 20. The second diagram is a circuit diagram in which the methods of the illumination device, /, and the brother 7 are different. As shown in Fig. 2, each of the LEDs 34a, 34b, 34c, and 34d and the current limiting resistor that determines the inflow of the LED current value are connected in series to suppress the current to several tens of mA or several mA. Moreover, in conjunction with the LED switching cycle, the output signal from the control device such as the microcomputer is connected to the transistor input of the series, thereby forming a circuit of the reverse switch LED, and when lighting [the rib, a fast cycle that does not feel flicker (for example, about 4 kHz) ) For the work cycle, during this period, the LED is energized/de-energized. Further, by controlling a control device such as a microcomputer such as a transistor switch, the power-on/off ratio (current rate) can be arbitrarily adjusted. Fig. 21 is a diagram showing the conduction ratio and the ratio of the energization time between the periods P1. By adjusting the conduction rate, the illumination of the entire illumination device can be adjusted. Further, the life of the LED illuminance depends on the energization time. However, as in the above method, when the LED is turned on and the power-off time is turned off, the ratio can extend the life of the LED. Moreover, by setting the energization/de-energization period to be faster than the human eye feels, it is possible to prevent the LED from appearing to be flashing k and 'when using this circuit, the current consumption can be reduced, so that energy can be saved more. . This cycle can be selected as long as it is preset and can be freely selected accordingly. In addition, with the power-on time of the power-on time, the port is named and the LED illuminance will be 3⁄4 low. By appropriately adjusting the power-on/off-time ratio (power-on rate), the illuminance of the LED can be kept constant for κ.箆2? s at the time when the main- 疋笫 diagram is not changing the power-on rate

7042-7134-PF 25 1299395 Figure. When the refrigerator is turned on, first, it is turned on at the initial energization rate β 〇 % (step 50). After the power is turned on, when the usage time elapses for one year (step 5丨), the power-on rate is changed to 70% (step 52). When the usage time elapses for 5 years (step 53), the power-on rate is changed to 80% (step 54). The power-on rate and the time of use vary depending on the type and number of light-emitting components used. Therefore, the data can be selected and the value can be adjusted to obtain the necessary minimum illumination. Further, as shown in Fig. 7, by changing or combining the number of lightings, not only an efficient device but also a device that does not need to be replaced during the use of the Φ refrigerator can be obtained. Further, as shown in FIGS. 22 and 23, although the configuration in which the number of LEDs to be lit or the current supply rate is increased in accordance with the operation time has been described, the deterioration of the LED is matched, that is, the illumination of each LED is matched. It is only necessary to increase the number or increase the conduction rate. Therefore, for example, it is also possible to change the illuminance by detecting the illuminance by providing a switch or the like that partially short-circuits the current limiting resistor.

Thereby, it is fixed so that the angle fluctuation is not caused by the vibration of the refrigerator, and not only the inner surface is covered with the gasket 36, but also the circuit is prevented from being short-circuited, and at the same time, in order to prevent the inside of the lid body 35 from being exposed, the 〇 type is sandwiched. The ring is exposed to a high degree of density to block the cold air, preventing the dew junction of the mounting substrate 33, or the light reflection caused by water droplets. Further, as shown in Fig. 19, the lid body 35 has a projection portion 39 which is formed to prevent the collision with the surface of the lid body, to prevent the light from being reflected by the surface of the lid body, or to wear the beauty plate 33. , LED34 damage and failure.

Even when such a plurality of types of illumination devices of different wavelengths are turned on for a long time, when the control contents described in the illuminance and the like are increased in combination, the illumination can be illuminated and the visual sensation can be suppressed when the door is opened. Further, when the LEDs 34 in the single unit of the illumination device 32 are LEDs 34 of a plurality of colors, for example, LEDs of different colors such as red or blue, the illumination device 32 is formed, and even if the illumination device alone can emit light of a plurality of wavelengths, the fruits and vegetables are It is possible to carry out various kinds of light forms, and the light system is a color that is warmer than the red color. Therefore, the appearance of the product and the appearance of the preserved food 7042-7134-PF 27 Ι·299395 are all better. The above-described light source is such that a plurality of optical semiconductor LED elements are provided with a plurality of light-emitting devices, and a plurality of components are mounted on the mounting substrate 33 to make the structure or wiring premature. However, only one of the LED components is disposed at one substrate. Alternatively, one LED can be arranged in the refrigerator compartment. As described above, the refrigerator of the present invention is configured such that red or blue is not used in a single color and is combined, or an illumination device that increases the illuminance in a late-night time by using a light source having a food preservation effect such as fruits and vegetables, may be the same The frequency or possibly different frequencies, the control makes the complex specific frequency [ED, time or time to light or extinguish] so 'by controlling the non-wasting energy, not only when the window is closed, 'even when the window is opened (10) It can be used as an illumination, and the appearance of foods such as non-members and fruits and vegetables can increase the amount of nutrients, and also has the effect of being able to use the light in the ice storage. Moreover, the light source of the refrigerator of the present invention is such that the LED intermittent shame 'X, the control makes each [ED instantaneously or in a predetermined cycle to switch the lights on and off, and control the energy saving", thereby prolonging the service life of (10), so that it can be obtained The effect of a good refrigerator.
