The cold air compressed by the compressor 12 is condensed in a condenser (not shown). The refrigerant in the condensed state is depressurized in a capillary (not shown) and a swellable valve as a decompression device. The cooler 13 is an element constituting a refrigeration cycle of the refrigerator, ..., π bait wind, and water phase, and the decompressed refrigerant evaporates in the cooler crucible 3, - the suction effect of the straw when bursting, the cooler 13 The surrounding gas is cooled. Α ... 7 The milk-repellent blower fan 14 is used for cooling the cold air around the cooler 13 to the storage compartments of the refrigerator body 1 (refrigerator compartment 2. The ice-making compartment 3, switching Room 4 The components of the sulfur recovery chamber 5 and the freezer compartment 6). The switching between the air volume adjusting device and the knife-to-use damper 15 serves to control the temperature in the switching chamber 4 by adjusting the amount of cold air blown to the cold air of the main switching chamber 4 by the cooling air circulation fan 14 Owe, dish. The cold air cooled by the cooler 13 is passed through the switching chamber cooling and the D-type air duct 16 and then blown into the switching chamber 4. Further, the switching chamber cooling buckle incineration type duct 16 is disposed downstream of the switching chamber damper 15. 7042-9822-PF 10 200923296 Fig. 3 is a plan view showing a spoon around the switching chamber of the refrigerator according to the second embodiment of the present invention. In the figure, a switching chamber housing 17 is disposed in the switching chamber 4. Further, one of the baffles 15A, which is the damper for the switching chamber of the air volume adjusting device, can be adjusted by the opening and closing adjustment (opening and closing angle adjustment) to adjust the flow into the cold chamber of the switching chamber 4, and switch the composite wind for the switching chamber cooling. Two lanes of the turnout 6. Here, the composite duct 丨β for switching chamber cooling according to the present invention is constituted by two cooling ducts of the direct cooling air 16 6A and the indirect cooling duct 丨 6B. (In Fig. 3, the composite duct 16 for switching chamber cooling is branched from the cooling duct connecting duct 16c connected to the raft to the two cooling ducts through the air volume adjusting device π (direct cooling duct) 16A and the structure of the indirect cooling air passage 16B), the switching of the two cooling air passages and the air volume adjustment are performed by the air volume adjusting device 15. The direct cooling air passage 16A is used to directly blow the cold air to the switching chamber 4. Wind tunnel. The indirect cooling duct 16β is a duct provided in the top insulating layer 18 of the switching chamber disposed on the top of the switching chamber 4 and used to pass cold air. However, at the top of the switching chamber 4, no cold air is blown. The air outlet to the switching chamber 4 'so' passes through the cold air of the duct 16β to indirectly cool the interior of the switching chamber 4 through the top plane. The direct cooling air passage 16 is provided with a f-face blowing 4A on the f-plane in the switching chamber 4, and the rear air outlet 4A directly blows cold air to the switching chamber. At this time, if the switching chamber casing _ which is the casing of the storage compartment is provided in the switching chamber 4, the rear side wall of the switching chamber casing 17 whose position is opposed to the back surface air outlet 4A is provided with an opening portion or a concave corner portion 'back air outlet' The sent cold air is blown into the switching chamber casing 17 through the opening or the concave portion of the back wall, and directly cools the food in the switching chamber casing 17, etc. Of course, the switching chamber casing 7042-2982-PF 11 200923296 17 may be omitted. The food or the like is directly stored in the switching chamber type, and in this type of energy, the cold air is directly blown into the interior of the switching chamber 4 by the back air outlet 4A, so that the food can be directly cooled. In Fig. 3, indirectly The cooling air passage 16β is not provided with a cold air blowing port that is blown to the switching = 4, but has been cooled by the indirect cooling air passage (10). The cold rolling is transmitted through the switching chamber provided under the switching chamber 4 or the side surface, etc. Returning to the cold room, at this time, if the cold air of the indirect cooling air passage 1 is slightly cooled or the cooling rate is slow, a blowing air can be blown to the air outlet in the switching chamber 4. If it is in the switching chamber 4 Cooling process The minute cold air or the cooling rate equal to the indirect cooling is a slow cooling air, and the blowing port blown into the switching chamber 4 or the switching chamber casing η may be disposed in the indirect cooling duct 16B for cooling. Further, if the cold air falls The speed is a slow speed that naturally falls, which can be regarded as indirect cooling.

Order cooling. The opening and closing angle of the block (4) is about 9 degrees (that is, if the approximate vertical output is 7 degrees to 1 degree = 8 degrees to 1 inch. If the degree is better), is it about fully open? Both the direct air passage m and the indirect cooling air duct β6β are opened, and both the direct cooling air passage 16A and the indirect cooling _ΐ6Β are cooled by both indirect cooling and direct cooling, so the heart reaches the setting quickly. ^ Temperature. At this time, the flow area of the direct cooling air duct ΐ6Α and the indirect cooling air duct 16 Β can be approximately equal, but the size of the storage room and the cooling setting can be cooled with the frequency of direct cooling and use.

When the board is fully open, the direct cooling duct 16A There is a cold flow in the household, which is easy to produce direct cooling effect. It is best to use the air passage area of the air passage 1 6A for indirect cooling ~ potassium for more than double, so when the collision plate is fully open: two: the flow area of the two The flow in the flow becomes easy, and it is easy to get straight: the effect of direct cooling in the direct cooling (4) j.) The opening and closing angle of the baffle 1 5A is 7 degrees in the middle angle, and the angle is preferably 35 degrees to 55 degrees. For the car, it is about 45 degrees (2 degrees to the state), direct cooling with the air duct 1 6A, the door is closed slightly, and the shape is open.

In the present invention, since the direct cold portion air passage 16A and the indirect cooling air passage 16B are twisted, it is possible to perform supercooling freezing or chilling freezing in addition to the slave freezing. First, the first knot is used to describe the supercooled state and the experience of cooling the cancer. The so-called speaking, entering, and jinming over-cold state means that when cooling water, it is lower than the freezing point (KC, ★, „ θ I, , & also maintains a state of 100% water. The so-called supercooling The state of water can be used to make the Kang, and σ into ice. However, in order to achieve this goal, it is necessary to give Yide 卞 卞 tea to stimulate. This kind of stimulation can be temperature stimulation or physical stimulation. In this way, the temperature stimulation is good, and the physical stimulation is good, 'the beaming can be started, but the time from the transition to the supercooling state to the beginning of the beaming is in seconds, that is, it is an instant. However, At the beginning of this freeze, the proportion of ice that freezes instantaneously is the whole percentage of the drowning water of the right ice east, which turns into milk; east. It must be further cooled before it becomes 100% ice. 'Although cooling time is required, The 东 is overcooled; the east knot is called overcooling (overcooling). The biggest difference between

If the state of (1) to (3) is controlled to obtain a sufficiently deep subcooling degree (temperature difference between the freezing point of the food and the temperature reaching the supercooled state), the effect is according to the state of (4) = (5). Will not disappear. However, when the cooling state % is reached, the right opening the door for a long time due to the ingress and egress of the food, or causing the set temperature to be above the freezing point temperature causes the temperature in the supercooling chamber to become 〇 or more = the supercooling state is released, and the slave state is again (1) Start again. Next, the steps (1) to (3) will be described. f亢' is based on the difference in the core temperature of the strip that is placed in the thickness of a soil 丄 ^ υ S 过 box. The state is cold, and it is frozen to grow. Here, the needle is large. The large ice knot food is described in the core of the solution. Next, the supercooling conditions in the glacial potassium of the present invention (in the same supercooling space) will be explained. In the process of setting: the points to pay attention to are the cooling rate and the food to be cooled: the low arrival point (the temperature reached in the supercooled state) and the freezing: when the cold part speed is too fast, the temperature of the whole food is uneven. Therefore, P (the difference between the surface temperature of the food and the core temperature is large), the part of the split and the unfrozen part. The ice crystal is centered on the ice core. If the part of the food is frozen, the side grows from the water side. As a result, I grew up. Acicular ice crystals grown in the intercellular space, etc., :: Bow: The water in the cells flows out, destroying the fine moon pack, causing the bundle to flow out of the juice.

7042-9822-PF 20 200923296 Finally, the original food tastes worse. On the other hand, the t-flavor is reduced, the nutrients such as free amino acids are reduced, and there is no maintenance. The right part is too slow to catch, and in the supercooled state, there is a time for bacteria to multiply, °, and 'but not frozen. Thus, before the bead node, the oxidation or the like causes a problem of food deterioration. That is, when the difference between the surface temperature and the core temperature of the core 7 is reduced, the cooling speed is made to make it early: at the temperature of two times (supercooled state), the cold portion is raised to make the future junction state The :: the minimum arrival point 'to solve the overcooling, before the point and at the freezing point to a too long S. In this way, the food is frozen or continued to enter the pole / ^, the grave 7 is disfigured and cooled, and evenly ordered to adjust to the Yuan Quan Guang Shi Shi ‘a gas adjustment. In order to solve this: the temperature control of each stage of the 'cold function method. It is anti-bacterial, and there is a method of adding antibacterial in the space of the supercooling. First # : The crime of raising costs will also arise. I first, for the over-cooling, A, people, (the cooling rate of the S-children, the cold part of the car, the center of the car according to the type of food, and the mouth of the mouth.) The speed of cooling food by heat conduction is also determined. After H, the cold of the center is controlled by the actual household refrigerator to control the change of the food, and the mouth will be 笳#, θ' and θ ""The surface temperature of the food, first of all, will be the surface temperature of the target. According to the food 婉^, s ώ,,, the diachronic change of the surface and center of the food produced by the work, the spear, κ °0 center The temperature and the surface temperature of the food are reduced by about the same tendency. The beef with the best 丨5_ and weight 15〇g is taken as the air around the R product, and the B7谇4^ rolling degree is set to arrive within 30 minutes. The temperature, for example, reaches -5, -7, ~10t:, ^ 〇 / / However, the time when the surface temperature of the food reaches the freezing point is 120 minutes respectively ^ Sickle clock, longer than 60 minutes

7042-9822-PF 200923296 * Time. The temperature difference between the food center temperature and the surface temperature of the food is relatively small, and each temperature difference is 0·5 to 3. 0 degrees (K). However, the higher the air set temperature, the smaller the temperature difference between the surface and the center, and the lower the set temperature, the lower the subcooling, that is, the energy at the time of freezing. The cooling rate is calculated as the surface temperature of the food is in the range of 3 °C to 0 °C. The temperature of the surface of the food is about 3.5 ° C / h, when the set temperature of the food is -5 ° C, the cooling rate of the food surface is about 3. 5 ° C / h, when When the set temperature is -7 °C, the cooling rate of the food surface is about 5 °C / h. When the set temperature is -10 °C which is very shallow supercooling, the cooling rate is about 10 °C / h. According to this result, the condition of influx supercooling is such that when there is a distance between the surface and the center of the food, the cooling rate of the surface of the food should be 10° (:/1) or less, preferably 51:/]1 or less. At this time, the temperature of the food surface and the center are also differently inserted. When the set temperature is -5 ° C, the temperature difference between the food surface and the food center is about 1 degree (K) (the cooling rate of the food center is about 3. 5 ° C / h), when the set temperature is -7 ° C, the temperature difference between the food surface and the food center is about 2 degrees (K) (the cooling rate of the heart in the food is about 5 ° C / h). On the other hand, when the set temperature is -10 ° C where the supercooling is shallow, the temperature difference between the food surface and the food center is about 3 degrees (K) (the cooling rate of the food center is about 10 ° C / h). According to this result, the condition of influx supercooling is that the temperature difference between the surface and the center of the food is below 3 degrees (K), preferably below 2 degrees (K). When the distance between the surface and the center of the food is small, that is, the food When the heat capacity is small, such as thin meat, the set temperature is lower than -10 °C, for example, even if the set temperature is -1 5 °C, When the degree of cooling does not become shallow, a good frozen food is obtained. 7042-9822-PF 22 200923296 It can be seen from the above that the cooling rate of the surface of the food is assumed to be a cooling rate of 3 degrees or less between the surface temperature of the food and the center. At this time, it is necessary to consider the following phenomenon. First, when the temperature difference between the surface and the center of the food becomes large, the density of the water contained in the food changes, and the convection of the moisture contained in the food is caused by the Therefore, the polymerization rate of water molecules increases, and the growth of ice cores is promoted, so that it is easy to release the supercooled state. Second, if the surface of the food is frozen first, the surface of the food is stabilized at a certain temperature of the freezing point. The environment that has come down becomes the whole food. Therefore, the food is stably maintained at the freezing point, and the cooling heat conducted from the surface of the food is completely utilized as latent heat, so that the freezing continues. Therefore, when the surface of the food freezes, the whole food does not become supercooled. On the other hand, the air temperature around the food is such that the food reaches below the freezing point in the unfrozen state. Degree will vary with the type and thickness of the food. However, in general, the temperature of the air around the food can be set to above -10 °C, and the upper limit of the air temperature around the food should obviously be cooled. The freezing point of the food is below -1, for example, for beef and pork, it is -1. 7 ° C or less, and for most foods, it is -2 ° C. The temperature difference is suppressed to be cooled below 3 degrees (K). The speed is about 3.5 ° C / h to about 10 ° C / h, preferably about 5 ° C / h or less. However, when the thickness of the food is less than 10 mm, such as thin slices of meat, it must be 5 ° C / mi η is poured into the subcooling. When the food is a blocky meat with a thickness of 40 to 5 Omm, a cooling rate of 2 to 3 ° C / h is required. Regardless of the type of food, the temperature difference between the food surface and the food center can be controlled within 3 degrees. However, for foods such as yoghur, which are easy to maintain moisture in a gel position and are easy to be homogeneously supercooled, it can be 7042-9822-PF 23 200923296 about 3. 5 ° C / h to about 10 ° The cooling rate of C / h is overcooled. However, if the set temperature is -1 8 °C, the temperature difference can be overcooled at 5 to 10 degrees. An important obstacle to the influx of supercooling and maintaining the supercooled state is the irregular temperature distribution around the food. For this, the degree of irregularity of the cooling rate can be controlled, that is, the cooling rate around the food can be made smaller. . Further, in order to control the air temperature to a certain fixed temperature, the refrigerator avoids fluctuations in the air temperature around the food due to the influence of various compressor operations such as opening and closing of the compressor, opening and closing of the compartment fan, and opening and closing of the damper. The temperature change inside the food will increase as the temperature of the air changes. Therefore, convection of moisture inside the food is promoted, that is, the polymerization rate of water molecules is increased, and the release of supercooling is facilitated. To avoid this, the influx of supercooled state, before the freezing point of the food (for example, -1.7 °C), that is, the temperature fluctuation before the inflow of the supercooled state, after experiment, about 6 degrees ( Within K). Regardless of the size or type of the food, it is impossible to give the surface of the food a cold but relieved stimulus. Therefore, the temperature change of the air around the food is as described above, and should be within 6 K. However, even if the degree of supercooling becomes lighter or the probability of supercooling becomes lower, a supercooling state can be created. For example, in the vicinity of the air outlet, in an environment where the temperature variation is greater than 6 K, such as 15 K, Influx is supercooled, and the overcooling can be deepened for foods that are easily cooled. To infuse supercooling and deepen the supercooling, it is not necessary to cool at the same temperature. When cooling is performed at a certain temperature, the food is cooled, the surface temperature of the food is lowered, and the temperature difference between the temperature of the air around the food becomes small, and the surface temperature of the food remains stable almost at the air temperature around the food. Therefore, if the supercooling depth 7042-9822-PF 24 200923 is to be circulated, the temperature difference between the food surface and the air temperature around the food can be maintained at a certain level or more, and cooling can be performed on the one hand. To this end, the degree of air around the food can be lowered depending on the surface of the food or the temperature of the center. In the step of overcooling and deepening in the domestic refrigerator, after a predetermined time (experimental review in advance, from the food into the refrigerator until the temperature of the center of the food reaches -1, for example, 2 hours), every The set temperature is lowered for a certain period of time (experimental review in advance, the time when the food temperature drops by rc, for example, 〇·5 hours). Thereby, the temperature difference between the surface of the food and the temperature air around the food can be maintained and the food can be cooled, so that the supercooling can be deepened. Conversely, when the degree of irregularity of the air temperature is large or the variation of the air temperature is large, the temperature distribution on the surface of the food becomes large, or the thermal conductivity of the surface of the food becomes large, and crystallization is started from a position where the surface is easily cooled. Release the overcooled state. -Generally, after the cold bed meat, fish, etc., if the ice crystals formed inside are large, the cells will be destroyed, and the amount of juice flowing out after thawing will increase. Therefore, if the amount of juice flowing out of the cold-cold and the cold-cold beef or box fish is compared, the juice outflow of the cold-cooler is now lower than that of the ordinary cold--half The following trends. Pesses such as potatoes have been used as foods that are not frozen. After making food such as curry rice, it is stored in cold bundles, and then reheated after the next day to eat. 'Although it is a daily operation in the average family, at this time, the potatoes are taken out separately, ground into a mud, and then cold-bound. It is common sense to make cold curry rice delicious. Such a cold and refreshing horse 钤 potato will make the potato soft and taste worse. However, when the curry rice was made by cooling the cold, the 7042-9822-PF 25 200923296 of the potato was almost squid after thawing, and there were two kinds of 'will not become soft.

丄乂, after freezing for a few half | rlJ, the stereo structure of T^ is changed [even after thawing] to maintain the original three-dimensional structure. In 1: Cooling in the cold • The taste of the deactivated potato will not be 3 Β This principle also applies to the unsuitable for cold; other foods in the east: 'This means 'if used to cool the cold, the previous discomfort The cold R product can also be used for freezing. As for the so-called α Ding 7 , it can be understood that when the food is cooled to the east, fine ice crystals are formed, so it is not

It is preserved in the case of the original food structure such as cells and proteins. In Yu, even if the food is frozen until it is thawed and then frozen and then frozen and thawed, there is a possibility that the quality will not be extremely deteriorated as it was in the past. The above has the advantages of being used in general households, but in the course of food processing, supercooling and freezing can also be effectively utilized. The fine particles of the ice crystals produced by the supercooling and freezing can give excellent results in the freezing at -6 °C, and the high-quality freezing can be achieved. In addition, since there is no need to use a large amount of energy to manufacture extremely low-temperature cold air due to business needs, it has the advantage of high energy efficiency. In the above review, it is assumed that the wind speed around the food is 7042-9822-PF 26 200923296 〇.5m/s. The difference between the temperature of the air temperature around the surface of the product and the air temperature of the food and the convective heat conductivity 氺 the smaller the rate, the speed of food, and the speed of the food. This ^ is 'convective heat transfer quickly becomes supercooled: and the temperature difference is smaller with 1:', and the time change is required to specify (a) 卩;:, /, although the temperature according to the temperature of the food surface temperature: ;;=Γ For the actual product, the 'food surface device can receive the thermoelectric stack from the second sensor'. This type of non-contact detection of the surface of the food produces heat, the switching chamber of the refrigerator, etc. Hunting this 'from the temperature of the thermopile after the food is placed in the temple, the temperature of the food is pushed out, and the thermoelectricity after the enthalpy changes the temperature of the food into the heat capacity of the food. Put the food into the long or shorten the control time in each step. :: It was originally an unstable state, which can be relieved by some kind of stimulation. Door gap 2: Although the solution can be released by vibration, when the water is filled in the sealed container with the gap of the cover... The half shovel ~, a under the circumstance, even if the container is vibrated violently -... to relieve the supercooling, Moreover, φ Ρ can not release 2 P if the pull-out space that enters the refrigerator is cut by Am + 1 repeatedly. However, when only W2 water is placed in the sealed container, it can be released. Therefore, if Panzis wants to hunter to relieve the supercooling by vibration, it is necessary to move the liquid freely. For the meat preparation,, - Temple R 0 and S, fill the ' ^ ^ M ' between the cells and the cells without gaps and the gap-free energy = container equivalent. In fact, in the switching room that has been cooled and cooled: meat, even if it is repeated. μ Wang Kai and full closure can not be removed, and when the cooling is released, the percentage of the whole food is reduced.

7042-9822-PF 27 200923296 The ice core is determined by the degree of subcooling. For example, when the supercooling yields 4 degrees (K), the ice core is formed by 5 percent of the moisture of the whole food, which can be understood by the mathematical formula of the freezing rate below. Freezing rate (%) = (Cp* rV* △ T) / L* rV* 100 Cp : specific heat (kJ/kgK) r : density (kg/m3) V: volume (m3) L: latent heat (kJ/kg)

△ T: Temperature difference (K) If the degree of supercooling is 4 degrees, the shape of the ice crystal is fine particles. After the supercooling is released, the temperature of the food is restored from the temperature below the freezing point to the freezing point (the temperature difference at this time is the degree of supercooling), and from this point on, the next step is opened, and the knot is turned into a frozen state. When the freezing point is reached, a phase change is obtained (if water is used, for example, from liquid water to solid ice), which is a state of transition at a certain temperature, after which the freezing is completed, and the frozen storage state is maintained at the set temperature. As long as overcooling occurs, the subsequent freezing rate does not affect the shape of the ice crystal, and when it is supercooled, a minute ice core is formed, and if the ice core is distributed throughout the food towel, the ice crystal of the whole food becomes fine. As described above, when the supercooling is released, the freezing rate is determined by forming the ice core by a few percent of the moisture of the whole food. According to the experimental data, when the degree of subcooling is 0.8 degrees, the freezing rate is about 100%. First, the ice crystals are large needle crystals. If the supercooling degree becomes larger before reaching 2-6 degrees, the ice crystals will become quite small, but the freezing rate is about three percent. If the supercooling degree becomes larger than 4.1 degrees, it will become impossible. Ice crystals discriminated by the naked eye, frozen 7042-9822-PF 28 200923296 The knot rate is about 100% dance. As described above, the ice core obtained when the supercooling is released is only a few percent of the entire food, and the ice core is generated in a uniform state throughout the food. Therefore, it is affected by the ice crystal state after the cryopreservation. Moreover, the energy accumulated in the supercooled state is used as the energy at the time of formation of the ice core, so that the larger the material p degree is, the more energy is accumulated, and the more the number of ice nuclei generated when the supercooling is released. Therefore, the ice crystal diameter also becomes small, and the influence of ice crystal on food damage is also small. As described above, in order to make the food stored in the ice compartment supercooled, it is necessary to cool by a certain range of cooling capacity. This means that if the cooling capacity of the food cooling is too weak or too strong, it cannot be made into a #supercooled state, or the supercooled state is quickly released. When the cooling capacity is too weak, the stored food is liable to enter a supercooled state. However, the cooling ability around the food is too weak to mean that the temperature is too high, and the point of arrival of the food temperature in the supercooled state also becomes high, so The supercooling is released when the supercooling is not deepened (that is, becomes a lower temperature). In general, the greater the degree of deepening of the supercooling, the greater the energy, the formation of fine crystals in the food, and the achievement of high-quality cold rolling. Therefore, based on the purpose of further deepening the supercooling, It is too weak to be established. Regarding the ice formation of supercooling, if it reaches 3 Κ (for example, after the food reaches the -4 state in the supercooled state (after reaching the minimum reaching temperature), the supercooling is released, and the temperature rises instantaneously to: -lt) above the freezing point, When the meat is thawed, the amount of juice outflow also produces a difference, and it is necessary to catch up with the overcooling deepening above it. (The difference between overcooling and deepening (the difference between the peak temperature and the minimum temperature) is as large as 3K or more. The smaller the juice outflow when the meat is consumed, the better the quality of the cold bundle.

7042-9822-PF 29 200923296 Conversely, when the cooling capacity is too strong, it will continue to freeze at the point of reaching the freezing temperature of the food, or even if it enters the supercooled state, it will immediately stimulate the powerful cooling capacity to release the supercooling. This leads to a lack of deep cooling. Therefore, it is necessary to cool the food with a certain range of cooling capacity. As described above, if the cooling capacity is weakened (equal to increase the temperature of the compartment), after the food is placed in the refrigerator, the temperature of the compartment is changed to -3 to -4 ° C, and the food is cooled at this temperature. Since the temperature is -3 to -4 °C, the food temperature must of course be lower, so that deeper subcooling cannot be obtained, so that although the temperature of the compartment continues to decrease little by little, the final temperature in the food is about - The supercooling was released at the time of 3 °C. If the cooling capacity is weakened in this way (equal to increasing the temperature of the compartment), although it enters the supercooled state, it does not go deep, so the user rarely feels a significant difference in food. Moreover, if the cooling capacity is increased (equal to lowering the compartment temperature), it will not enter the supercooling state, and when it reaches the freezing temperature, it will start to be inconsistent. However, if the air temperature is set to -1 0 °c or more, the compartment temperature is only lowered by 4 to about -7 to -8 ° C. However, the deepening of the supercooling to 3 K or more is sufficient at this temperature. Further, when the set temperature is lowered, if the temperature is lowered from the vicinity of the freezing temperature of the food (about -1 ° C), deeper supercooling can be obtained. Further, when the temperature is lowered, the temperature can be lowered little by little without giving a strong stimulation to the food. For example, when the set temperature is gradually lowered by 2 degrees, the state of overcooling is finally released. When the set temperature is gradually lowered by 1 degree, the stimulus caused by the temperature gradient is alleviated, so it is not released. Overcooled. 7042-9822-PF 30 200923296 Next, as already explained, as another necessary condition for supercooling, the air temperature distribution in the vicinity of the supercooled target food is also included. This is because if the food is not set under a certain range of air temperature distribution, it will not enter the overcooling state or the phenomenon of immediately releasing the supercooling. The reason is that the freezing of the lower temperature portion of the temperature distribution of the food or the release of the supercooling results in the expansion of the food to a higher temperature, causing it to freeze or be desupercooled. Therefore, cooling in a certain range of temperature distribution becomes a necessary condition. Specifically, the smaller the range of the air temperature distribution, the better, but the variation of the refrigerator entity, the size and shape of the food to be stored, and the like, and the temperature distribution range is preferably about 2K or less. In the state unrelated to the temperature of the compartment, if the temperature distribution range and the degree of deep cooling are collected in a statistical manner, it can be judged that when the temperature distribution range reaches 2 K or less, the probability of supercooling is increased. By correlating this condition with the temperature settings described above, the probability of discovery of supercooling can be very close to 100%. In order to adjust the cooling intensity, the temperature is kept constant by a damper or the like which is adjusted by a switch of a compressor mounted in the refrigerator and a temperature sensor provided in each compartment. Thus, in each compartment of the refrigerator, there must be time for supplying cold air and not supplying cold air (cooling air on/off). Thus, in order to adjust to the set compartment temperature, it is necessary to supply cold air which is lower than the compartment temperature. However, in order to achieve a supercooled state, the food must be subcooled at the above temperature. In this case, it is sure to continue cooling at a temperature above -1 °C, preferably at -10 °C, which is a necessary condition for the air temperature in the vicinity of the food. However, in the real life of the household refrigerator In the realization of the temperature 7042-9822-PF 31 200923296 It is difficult to search for a small amount of ambient air, and it is necessary to control the temperature of the cold air around the food that has cooled the target. The implementation method is roughly divided into two. First, the first is a method in which the temperature of the cold air that cools the compartment approaches the optimum temperature for supercooling. Usually, when cooling, the temperature can be set in the refrigerator in the cold two: range, such as the interval of the cold air supply in the cold air supply, σ (blowing $ port) can reach about -25 ° C. This temperature is a very different value from the optimum temperature for supercooling, and it is effective to control the temperature of the source of the cold air supply. With regard to this method, this method of first increasing the cold temperature by reducing the cold-blowing ability of the I-shrinking machine is included. However, 'the original cooling capacity beyond the cold must be ensured in advance, so 'do not reduce the capacity of the compressor itself, and s % 丄 士,士,, π 疋 疋 转换器 转换器 转换器 转换器 转换器 转换器To reduce the driving force of the compressor, the cold air supply temperature m, the low freezing capacity, the increase will be found, the speed of the machine is reduced, and the brewing degree is also increased by about 3~5 [again, in the supply of cold The temperature of the air supply fan can be changed, and the temperature of the ice can be changed. In fact, when the 对 small π 状 衩 供应 supply cold rolling convection heat conduction is suppressed, the γ wind speed is also reduced,

In addition to the skin, it is also possible to consider the temperature of the air-conditioning supply. The first method is not to raise the air-conditioning. The first method is not to raise the air-conditioning.

7042-9822-PF 32 200923296 Gas is not directly blown onto food. In order to achieve this method, it is included in the method of lengthening the cold table for hire, for example, the distance to the air-conditioning of the food. For example, a cold air rectifying guide is provided around the helium oxygen supply port, and the air outlet and the D & In this way, the food of the food week is blown: =; the heat exchange in the middle rises, and the air-conditioning is also reduced, so that it can be carefully cooled without giving it. Use the outer cover =::: to increase the outer cover of the food storage box and place the cold air outlet on the back side of the door sill to more than half. When the distance between the openings of the storage box is taken as the length of the storage box, when the airflow in this case is analyzed, the food can be increased by the addition of the outer cover, and the wind speed can be reduced. In addition, between the refrigerator and the air blower in the refrigerator, the limit of the control of the cold air supply should be reduced by the angle of the cold air, such as reducing the amount of cold air: =: fully closed, fully open, and can be adjusted To medium damper opening, μ control.

The temperature near the temperature is the appropriate temperature for overcooling. = Regarding the method of improving the temperature distribution, the temperature distribution range and the search can be suppressed by reducing the number of people supplied with the air. The method reduces the I reduction machine 1 as described above. Speed, supply higher cold temperatures

Therefore, this is an effective method for reducing the amount of cold air by adjusting the above-mentioned damping @ angle f#. The cold air temperature, the wind speed, and the like can be adjusted by the shape of the air guide that the person exports, the cold air outlet, and the food: the shape of the obstacle: the shape of the object. Then the case of rapid freezing in the next month. In the case of rapid freezing, the freezing and the sputum-sα, and the state after the freezing of the child and the cold air against the surface are made (the early _ point * LJL · point and the general freezing condition are the same. In the case of a rapid cold beam (rolling), it is known that && F is relatively frozen, so that the cold air with a low temperature is rapidly rushed to the surface of the food, etc., and the temperature of the surface is drastically lowered. It is the same as the general freezing, and it hangs from the surface and hangs from the sweat σ / East, but the difference from the general knot is that 'the cold air with a low temperature is quickly rushed to the surface of the food, etc., so it is cooled to the inside.

When considering the cold food of the food, the ice crystals after the completion of the east knot are small and the shape does not have a great influence on the quality of the food when the knot is unwound. Most of the food is made up of WD neck, such as cells, proteins, and sugar. Therefore, when the ice scorpion destroys its structure, most of it cannot be completely restored to the original 16.

Therefore, after the beads are removed, the food quality such as taste, texture and storage state of the food can be said to be good. Therefore, in the case of supercooled freezing which has been subjected to the freezing state freezing, the ice core is small and fine, and the ice core is in an approximately uniform state in the cold food target such as the whole food, so that it is colder than the The rapid cooling of the Park, the food quality is good, can be said to be the best choice. Next, the advantages of Dongjie Food and the advantages of the new special features by freezing and freezing the food are as follows: (4) Cold Kang ^ has been described so far, after passing through In the case of cooling, freezing, freezing, freezing (cooling and freezing), it is cooled to the inside of the food within the temperature difference between the surface and the predetermined temperature in the process of becoming "P趴," The R mouth is formed into an ice core in a roughly uniform state to form: a granular ice crystal. Also, the number of ice cores that are unfrozen and still exhibits overcooling, "t take low enthalpy (take low arrival temperature) and freeze point" is the number of ice cores that are kept at the beginning of Kangxi As a result, the fine iron/water crystals are formed, and after the supercooling is released, the ratio of instantaneous ice to ice, t σ, and good freezing quality are transmitted. Therefore, if supercooling is sufficiently caused (to k cooling) The temperature of the state, .4. X is lower), after thawing after supercooling and freezing, it can be maintained: like the bundle: the state before, the quality of cold washing is good. The cooling of Japanese and 艮οσ and the size of ice crystal, The relationship between the shapes of the day's ' needs to be considered as the passage of the temperature range::: crystal generation range of _rc ~ - 5t this if / 4 - 士 ° between. In the process of - freezing and rapid freezing, right in In a short period of time, 'in the H "" 1 crystal production range' ice crystals are small. No part is cold; in the east, if the unfrozen overcooling state is maintained,

7042-9822-PF 35 200923296 » Even if the temperature range (between -1 °c and -10 °c) including the maximum ice crystal generation range (-It~n) is long, it is not damaged. The quality of the food is frozen. When the field is cooled and frozen, 'the unfrozen supercooled state is maintained in the temperature range (near -rc~10〇c) including the maximum ice crystal generation range (-1c~5c) The time spent (the time spent in the state of supercooling, that is, the state of not freezing) is longer than that of normal freezing and rapid freezing (the passage time is longer). However, if it is in a supercooled state, the passage time (-rc~_1 (near TC) in the vicinity of the range containing the maximum ice crystal generation range (-1 to -5 °C) is very long. The frozen ice crystals do not become large, and fine ice crystals can be produced in a roughly uniform state. In the freezing using the temperature range in the vicinity of the maximum ice crystallization temperature range, the present invention is cooled and frozen. The method of thinking is a new cold/east method in which a large number of small ice crystals are formed to achieve good quality freezing. Further, it can be confirmed in advance that in the supercooling state of the present invention, when the supercooling state is released, The freezing starts, and after the phase change with constant temperature, it is completely frozen. However, if it is cooled, in the subsequent freezing process, even if the range is generated by the maximum ice crystallization, the time is long (even if it stays at the maximum ice for a long time). The range of crystallization is), the ice crystals will not become hypertrophy, the ice crystals will be very fine, and will be roughly uniform in the whole food, and can be cooled and frozen under high quality. In terms of point, it can be said that it is a new type of cold card. If it is cooled, even if the subsequent freezing process takes a long time, it will hardly affect the ice crystal state. Therefore, there will be no 7042-9822-PF. 36 200923296 Q5 No 4-'ja After the cooling state is released and the freezing process is entered, the ice is cold and the ice gentleman S k water, and the possibility of sweet fat is lower, so the quality of the product can be obtained. Moreover, it is possible to avoid the factors other than the factors related to the ice crystal crystallization: (e.g., recent reproduction, etc.), so that it is possible to perform a colder quality, and, so far, it has been taught that The food in the state of the state in which the food in the cooled state is cooled and then frozen, and the food W in the state of being cooled is required to be kept in the supercooled portion which is maintained in the supercooled state without being frozen, because it is in Dongsha, θ at the end, , , ° / liters below the same as the general freeze done under the degree of preservation is irrelevant, for the social day of the # 疋 疋 100 hundred knives of the hundred knots, not all formed ice y- excellent 2 for, one Aspects can be stored at low temperatures, the other side But almost completely 皤4 曰U, water π day to produce food structure... right to save the change reed &; a red city JS mouth of various chemical deficiencies U and ^ can effectively maintain fresh Degree, however, the two advantages of this unfrozen can be in this - ' 皿 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , In addition, the state of the frozen and the mouth is the same. Therefore, the cooling state 11 in the food means a cut-off state, and the lack of freezing of the knife in the middle means that the bacteria may have the moisture. However, if it is used as the present invention ::; After the ρ state, the cold cooling of the cooling is performed, and the second?:= is in a good state. Therefore, in the supercooled state, the mouth is preserved) compared to the preservation after the rolling (over Cooling cold roll) save (cooling protection

There is no possibility of paying attention (however, if the quality of short-haired food deteriorates to three weeks), there is no problem. , ', and save the work (for example, a 7042-9822-PF 37 200923296 Next, the operation of the display panel 60 and the control device 3〇 will be described. The stored food becomes a supercooled cooling chamber, that is, the switching chamber For refrigeration (about 3. 〇, condensation (about 〇t), soft cold; east (about - 5 7 knife U, cold Kang (about 7 〇 C below) and other multiple temperature ranges, about this: degree, by The control device 30 of the microcomputer or the like provided on the upper portion of the rear portion of the refrigerator main body controls the damper, the compressor, the blower, and the like, and switches the set temperature to the temperature. The display panel (10) provided on the surface of the sill is, for example, the fifth. 〃 f 5 is a liquid crystal display panel representing an embodiment of the present invention. On the display panel 6〇 in the figure, there is provided a selection of any of the refrigerating compartment, the vegetable compartment, and the switching compartment. One of the compartment selection switches 6〇a, selected: temperature adjustment between the room (storage room) or the choice of rapid cooling temperature adjustment / each _, select the subcooling of cold cooling (instant cold): Two r: _c, from the general, transparent, rapid, stop green selection system = two: change the switch 6 ° d. (Here, the supercooled cold bead is used for the instant lingering. In the present invention, it can also be called the instant cold beam.) In addition, the display can be displayed on the display panel 60, and the zucchini is changed. Room, ... the compartment of the dry space (refrigeration room, cold rolling room, cutting temperature, etc. In addition, in the use of non-connected t set temperature and the current port - production 矣 * "infrared sensor, thermopile measurement , food mouth (four) to, if the measured surface temperature of the food is not as good as the mouth _

The surface temperature of the product can be seen as a result; ^ panel 6 〇 on the 'cooling state, food time flow, close the mouth / 'for the user of the refrigerator' can be quite convenient. "To what extent ~ does not need to open the door to confirm, 7042-9822-PF 38 200923296 Here, if you want to perform rapid freezing, you can enter the rapid freezing by continuously pressing the temperature adjustment / quenching switch 60b for a predetermined time (3 seconds) In the mode, it is rapidly cooled. In addition, if the cooling bead is cooled (instantaneous cold rolling), the supercooling mode may be performed by pressing the supercooled freezing (instantaneous freezing) switch 60c to perform supercooling cooling or supercooling freezing. In the refrigerator of the present invention, including the ice box cleaning mode, if the ice making switch 60d is continuously pressed for a predetermined time (about 5 seconds), the ice box cleaning mode is entered, and the ice box is cleaned. The temperature adjustment between the compartments (storage chamber) can be performed by the temperature adjustment/quick switch 60b. In the present embodiment, the temperature is displayed in three stages of strong, medium, and weak. This temperature display can directly display the set temperature. On the display panel 60. Further, the set temperature of the cooling chamber can be set in the supercooled state, the supercooled state can be released, and the refrigeration can be performed after the release. In the case of the three phases, the set values are switched sequentially or continuously. This setting switch can be automatically switched to the previously set temperature according to the time interval generated by the timer set in advance. However, it can be set in the refrigerator. A switch or the like is provided on the liquid crystal panel 60 of the chamber 2, and the temperature to be set is manually switched. The temperature of the cooling chamber (for example, the switching chamber 4) before the cryocooling is released and further frozen storage is performed by the thermistor. 1 9 detects the room temperature, or detects the temperature of the surface of the food, and uses it as a set value, and is controlled by a cold air adjusting device such as a damper. Further, it is of course possible to use an infrared sensor 22 for measuring the temperature of the food instead. The thermistor 19 measured at room temperature controls the compressor 1 2, the damper 15 and the like. As described above, for the supercooled state, the temperatures of the freezing compartment and the cooling compartment are set according to the first temperature setting, by introducing The cold air in the cooling chamber causes the food 7042-29822-PF 39 200923296 to become supercooled. Then, the temperature difference is first stored, and the temperature difference is subtracted from the first temperature. After the second temperature is released, the food is supercooled. If it is judged that the supercooled state has been released according to the temperature state of the food surface, the food is frozen and stored. Thus, the switch of the refrigerator threshold is adjusted according to the third temperature set. In this case, the first set temperature, the second set temperature, and the third set temperature are separated by a time interval, or the temperature of the food is measured to sequentially change the three temperatures, so that the software can be stored in the microcomputer. The cold air is adjusted by a simple structure, so that if it is not subjected to rapid freezing or if it reaches an extremely low temperature such as -60 ° C, it is possible to achieve a cryopreservation of food which can achieve low energy consumption and excellent quality. The time interval may be stored in advance, and the time may be set by the liquid crystal panel 60 on the surface of the threshold. Thereby, the food can be processed early. Further, it is possible to judge whether or not the supercooling is released by measuring the temperature of the food to obtain an excessive degree of deterioration. Further, when the food to be stored is supercooled, the temperature of the freezer compartment and the cooling compartment for storing the food is adjusted according to the first temperature k degrees stored in the microcomputer, that is, the temperature set in the setting device, and the adjustment is to be introduced. The amount of cold air in the cooling chamber at which the temperature is set is influxed into the supercooled state, and the subcooling state is continued. Then, after the time required for the supercooling state to be supercooled, the supercooled state of the food is released, so that the cold air is supplied below the first temperature, the supercooled state of the food is released, and the food in the supercooled state is released to be placed at the threshold. The third temperature set on the surface temperature setting device is cryopreserved. If the first temperature setting is stored in advance, the set third temperature can be easily switched manually, so that settings independent of each other 7042-9822-PF 40 200923296 can be performed. However, when the first temperature is set, the temperature setting means may be provided on the door surface of the refrigerator and the side of the cooling chamber to be switched in order to change the type according to the type of the food. These temperature setting states and the temperature state detected on the surface of the food can also be displayed on the liquid crystal panel 60, and the set temperature can be changed while being displayed. For the third temperature setting, it can be a switched configuration, switching to the following temperature ranges: an ultra-low temperature range of -30 ° C to -60 ° C for long-term storage of more than several months, due to -5 ° C to -1 A fine ice crystal of 5 ° C which allows a person to use a kitchen knife to cut a weak freezing temperature range or a cryopreservation temperature range in the middle thereof. When the temperature is set, in order to change the temperature detected by the sensor to the temperature range to be switched, the control device 30 performs switching control such as the rotation speed of the compressor 12 and the opening and closing of the damper 15. As described above, since the first set temperature and the third set temperature can be set independently of each other, the supercooling state required for the storage period, the use state, or the like, or the type of the food to be stored, can be continued. The time, the degree of supercooling, and the set temperature are changed, so that flexible storage can be performed. Further, when the temperature of the indirect cooling cooling chamber is set, the room temperature can be measured by a sensor provided in the cooling chamber, and the room temperature can be estimated from the elapsed time of the cooling wall surface to determine whether it is intended to change the food to a supercooled state. The first temperature. The temperature of the cold air which is indirectly cooled can be lowered at a temperature lower than the first temperature at which the food stored in the cooling chamber is supercooled, and the wall surface temperature can be lowered to cancel the supercooling. Alternatively, by increasing the rotational speed of the blower fan in the sealed cooling chamber to increase the wind speed around the food, 7042-9822-PF 41 200923296 further increases the conductivity of the food surface and releases the supercooling. The more the degree of distribution of the surface of the food is uneven, the easier it is to release the supercooling. The opening of the cooling cooling chamber is released by the supercooling state releasing device that releases the food in the supercooled state, and is directly introduced into the storage compartment. The cold air preserves the above foods, or continues to indirectly cool, so that the temperature of the wall surface is further lowered and maintained at a low temperature, and the food in the storage room is cooled = so that it can be simply constructed to carry out cold energy consumption. Beads are preserved. Fig. 6 is a flow chart showing another control example of the damper for the switching chamber of the refrigerator of the first embodiment, which is a control flow when the cooling is performed. The structure of the water is the same as that of the refrigerator shown in the first, second, and third figures. Here, ^ indicates that the cooling is cold. The cold-cooling mode in which the supercooling and the cold-rolling are in a state of being supercooled is a state in which it is not smashed in a state of a helmet under a freezing point of a substance such as a food. Here, the so-called beam junction: 温度 the temperature at which the substance begins to freeze. In other words, the supercooled state means that a substance such as a food has a temperature that normally starts to freeze but is not finished: a frozen heart, for example, a freezing point of water. . The freezing point varies with the substance, and the rolling point of foods with higher salt concentration and higher sugar concentration is lower. . The tendency of C: ..., here, with reference to the flowchart of Fig. 6, the method for controlling φ!1 for realizing, partial & In the supercooling mode startup step, start (4). As the main overcooling mode start Ii, display panels (buttons, etc.) and _ (not shown) are provided on the threshold of the refrigerator, and these devices (buttons, switches, etc.) activate the supercooling mode by the user's operation. After the β V step S11 has elapsed and the potassium hydrazine type is activated, the process proceeds to the compressor operation state confirmation step M2 for determining whether the compressor 12 is in operation or not. In step Μ 2

7042-9822-PF 42 200923296, if it is determined that the compressor 12 is in the stopped state (JV0), return to step S12, "If it is judged that the compressor 12 is in operation (yes), a, month y enters the switching chamber damping The first step is s丨3. In the switching chamber damper opening step - S13, the switching chamber damper 15 is opened to a predetermined angle 0]. degree. Step S14 is a first step of determining whether or not the switching chamber temperature sensitive resistor 19 as the switching chamber temperature detecting means is at a switching chamber temperature lower than a predetermined temperature T1 (). In step S14, if it is judged that the temperature detected by the switching chamber thermistor -9 is greater than the predetermined temperature by 1 () degrees (Ν〇), the process returns to step S3. In step S14, if it is determined that the temperature detected by the switching chamber thermistor 丨9 is equal to or lower than the predetermined temperature L (YES), the process proceeds to the switching chamber damper opening two: step S15. In step S15, the switching chamber damper 15 is opened to a predetermined angle of 0 η degrees. In step S16, it is judged whether or not the temperature detected by the switching chamber thermistor 19 is equal to or lower than the predetermined temperature Τ, ! In step S16, if it is determined that the temperature detected by the switching chamber thermistor 19 is greater than a predetermined temperature Τπ degrees (N0), returning to step 8丨5 D in step S16, if it is determined that the switching chamber thermistor is The detected temperature is 9 or less below the predetermined temperature (YES), and the process proceeds to step S17. In the third step S17 of the switching chamber damper opening, the switching chamber damper 15 is opened to a predetermined angle 0]. Degree, then proceed to step Magic 8. Step S18 is a supercooling mode end step, where the supercooling mode ends. Here, the predetermined angle 0 " degree can be about 9 degrees (about 7 degrees ~ Π 0 degrees, preferably 80 degrees ~ 100 degrees), the air is blown to the switching chamber and the direct cooling air passage 16A The air is blown by the air duct 16B for indirect cooling. Therefore, the knife is changed to 4 or the portion directly flowing into the cold air is cooled earlier. Established temperature

7042-9822-PF 43 200923296 τ〗 ° ° is the freezing point of food, mainly the freezing point of edible meat, about rc left and right. Of course, the freezing point is not limited to this value. In step S14, after reaching the enthalpy service T1 ° C, the process proceeds to the switching chamber damper opening second step S15, and is switched to the damper 15 to open to a predetermined angle θ η degrees. The established angle Θ " degree can be abruptly 45 degrees (20 degrees ~ 7 degrees, preferably 35 degrees ~ 55 degrees), which is the baffle 15 Α approximately closed direct cooling air duct angle of 16 people. Therefore, during the period in which the baffle plate 15 is opened to the extent that the sentence is 45 degrees, the food in the switching chamber 4 is indirectly cooled by the cold air flowing to the indirect cold air duct 16 and is not blown from the direct cooling. The cold air used for the direct air-cooling of the road is so that it can be in a supercooled state without being strongly stimulated by direct cooling. Here, the predetermined μ degree Tu degree is a temperature for judging the transition from the supercooled state to the frozen state, for example, it may be 〜5t. The frozen state will vary with the size and shape of the meat. If the pork is about 丨〇〇g, if it can be subcooled to below -5t, it can be turned into a 100% state. Cooling: East knot state) 'can get high quality overcooled and frozen state. Fig. 7 is a side cross-sectional view showing the periphery of the switching chamber of the refrigerator of the first embodiment. A switching chamber housing cover 2 is provided on the switching chamber housing 17 and a top air outlet (10) is provided on the switching chamber top insulating layer 18. The top air outlet blows the cold air from the indirect cooling duct 16B to the outlet inside the switching chamber'. However, the switching chamber casing cover 2 is provided. , become air-conditioning === change room:: '17 in-house cooling method of food. If the frozen food is frozen (the rapid freezing of the New Zealand time), the switch panel 20 can be removed to strain. In the configuration in which the switching chamber cover 2 () can be removed, if the switching chamber cover 20 is removed, only the switching chamber cover (4)

7042-9822-PF 44 200923296 White: Part of the air duct resistance from the cold air of the indirect cooling duct 16β is changed to J,: more air is cooled from the direct cooling duct 16A and the indirect cooling air. The suppression of 1 6B through several positions (at least the back and top) and then into the switching chamber housing 17 'so' can achieve earlier rigor. On the contrary, if you want to carry out the cold and cold cooling, you can install the switch chamber cover, and the right can not find the position where the switch room cover 2 is removed. The board 2◦ moves to the structure that switches the outdoor compartment I?. In other words, the configuration may be such that when the switching chamber housing 17 is pulled out, the switching chamber housing cover 20 is fixed to the top or the side of the switching chamber 4, or the like, or the housing cover is locked at the top or the side of the switching chamber 4 or the like. When the switching chamber casing 17 is pulled out, the switching chamber casing cover 2Q is left in the switching chamber 4, so that only the switching chamber casing 17 can be pulled out. Further, in Fig. 7, the switching chamber housing cover 2 is configured to cover the upper opening portion of the switching chamber housing 17, but the 'switching chamber housing cover does not need to completely cover the upper opening portion of the switching chamber housing 17'. The direct cooling cold air blown out from the back surface air outlet 4A of the direct cooling air passage 16A hardly enters the switching chamber casing 17 through the upper opening portion, and can be replaced only after the outer casing 17 is placed. In other words, in the case of switching the chamber casing cover 2, when the cover plate 20 is placed on the switching chamber casing 17, it may have a front opening portion before the refrigerator: the side opening. X ' at the position where the indirect cooling cold air enters the switching chamber casing 17 through the front opening portion' may be provided with the blowing port 1 8A of the indirect cooling air passage 16B. When indirect cooling is performed, it is preferable that the cold air does not enter the switching chamber casing 17, but if the cold air entering the switching chamber casing 17 is in a natural falling state, it is the same as the indirect cooling, and there is no problem. 7042-9822-PF 45 200923296 In the present embodiment, the opening 4A of the direct cooling air passage 16A is opened as close as possible to the air volume adjusting device 丨5, and the indirect cooling air duct 16 6 is blown out ϊ 8A It may be away from the position of the air volume adjustment device 〖5. Thereby, when it is blown out through the air outlet 18A indirectly through the air passage, the wind speed is lowered by the flow path resistance or the like, and the wind speed and the air volume suitable for indirect cooling are obtained. Further, the cold air blown through the opening 4A of the direct cooling air passage 16A can be immediately blown into the interior of the shifting chamber 4 and the inside of the switching chamber casing 7 so that the wind speed and the air volume suitable for the rapid cooling can be obtained. Fig. 8 is a detailed view showing an important part of the periphery of the damper for the switching chamber of the refrigerator of the second embodiment. The switching chamber damper 15 described so far is a single damper having only one baffle plate 15A. Here, a double damper for switching chambers is provided on the direct cooling air passage 16A and the indirect cooling air passage ι6Β. An example of 21. The double damper 21 for switching chambers includes two 21-core indirect cooling brackets 21B for direct cooling. The direct cooling bracket 21A and the direct cooling Γ are connected by the channel m: the indirect cooling bracket 21Β and the indirect cooling duct (10) on the direct cooling bracket 21Α and the indirect cooling bracket 21β, and the eight opening and closing brackets 21C, 21D By opening and closing the two two, the road is thrown for direct cooling with wind (four) eight and indirect cooling with wind. In the present embodiment, the damper for the switching chamber is double b D . Therefore, the number of brackets is two, which can be extremely fine. In the case of controlling the 2 Nitors in the wind using the Pyang, and the A, the * is adjusted by the opening degree of the baffle, although it can cause the direct cooling air cooling duct 16B to open.

If this is the case: connect the cooling air to the device 21 and directly cool the air duct (10). When you don't need to make the system, you can do it independently and meticulously. Therefore, the cold part of the department is more than _, that is, when you want the speed of each speed, the speed of the W-speed, 21B, 2%; 'If the indirect cooling is turned off beforehand, the direct cooling air duct 16A can be efficiently ventilated. Therefore, the rapid freezing is performed. On the other hand, the advantage of # σ is that the number of branches is... The use of the early damper is small and efficient, so that the capacity can be compared with this. From this point of view, expand the Bedding room or the refrigerator. The picture shows the side of the switch room around the switch room of the first type of refrigerator. At the top of the switching chamber 4, Μ, ° is also used as the switching chamber temperature detecting device, and the external line sensor 22 is used, and the inside of the switching chamber 4 (or the switching chamber housing 17) Inside) the table of good products, and, the product, sore J., phoenix. In terms of the position of the S, the position of the imitation && 1 can be switched to the inside of the outdoor and the top of the switch room 4 is quite suitable, but the 'indirect side or bottom can also be indirectly The surface temperature of the food was measured. Further, the surface temperature of the food in the clam block switching chamber 4 (or the switching chamber casing 1) can also be measured by switching the outer cover 2 〇. Temperature detection If the infrared sensation is used, the switching chamber thermistor 197 can detect the temperature closer to the food (such as the surface temperature of the food) than the temperature of the switching chamber thermistor 197. Therefore, the supercooling can be improved. The chance of success. If a switching chamber thermistor 使用 is used, only the temperature near the switching chamber thermistor 19 can be detected, in contrast, red

7042-9822-PF 47 200923296 The external line sensor 22 has a feature of detecting infrared rays emitted from the surface of a distant substance, so that the temperature closer to the food (surface temperature of the food) can be detected. The amount of infrared rays emitted from substances such as foods is higher in temperature. Therefore, the amount of infrared rays detected can be measured by the amount of infrared rays detected. Here, in order to perform supercooling storage or supercooling and freezing, the temperature difference between the surface temperature and the center temperature of the food or the like is preferably small and is cold potassium in a state of approximately one. Therefore, in the present embodiment, The type, size, thickness, weight, etc. of the food in the switching chamber 4 (or = in the chamber casing 17) are measured, and the surface temperature is measured. From this surface temperature, the center temperature is estimated experimentally, and then the surface temperature and the center temperature are estimated. Temperature difference: Holds the cooling state. In the present embodiment, when the temperature difference between the surface temperature of the food and the temperature is 5 deg or less, it is preferably one or less, and the subcooling state can be maintained, and it is confirmed by experiments that the quality of the food after unwinding is good. In addition, please refer to the refrigerator of the first embodiment which realizes the supercooled state, ... "cold control flow chart. In the supercooling mode [but the mode starts.

7042-9822-PF 54 200923296 Refrigerator or storage for storage. Donggong: This 1st March's as a cold-drying function of horse quality, using over-cooling and freezing gongs instead of learning, L7, heart-thirsty, so, it has a high-quality cold-kang that effectively achieves less energy consumption. That is, the effect of environmental protection and energy saving. The ice phase of the present invention uses a temperature-controlled cooling structure in which cold air can be used to cause supercooling and the cold name P is selected as g +, A + muscle and /, and there are plural kinds of changes. The structure and control of the refrigerators that are not far apart can produce the effect of supercooling and freezing of foods such as meat. According to the invention, the infrared sensor is used for the temperature detecting cracking, so that the surface temperature of the food can be measured, and the temperature closer to the food (for example, the surface temperature of the food) is measured at θ 4, #至使The success rate of supercooling and cold heading is improved, so it can provide good cold storage of food quality (supercooling). According to the present invention, since the supercooling and cooling function of the tumbling in the supercooled state is included, the size of the ice crystal formed at the time of the east knot can be performed: the shape is difficult to destroy the freezing of the original structure of the food. Further, since the ice crystals are small, even if the ice crystals are destroyed, the state of the original state can be obtained, and after the teasing, the food quality such as taste, texture, and preservation state of the food can be said to be good. Moreover, since the supercooling and freezing function which is frozen in a supercooled state is included, the ice core is small and fine, and the ice core is approximately uniform in the frozen object such as the entire food, so that it is compared with the two frozen and Quickly frozen, good food quality. The refrigerator of the present invention changes the specifications of a part of a general refrigerator, whereby a refrigerator which can be supercooled and frozen can be obtained. In addition, the description has been made centering on the structure of the domestic refrigerator. However, for the large-scale extremely low-temperature business = 7042-9822-PF 55 200923296, the frozen warehouse can also use the concept of the present invention, for example, it can be used for some kind of control. The structure is such that after the food is stored, the temperature is lowered at a predetermined cooling rate before the freezing point, and the temperature is lowered little by little at a cooling temperature higher than the target food. While maintaining the cooling by the supercooling, after a predetermined period of time, the low temperature is directly blown to the food, the rapid freezing is performed, the supercooling is released, and then, the freezing temperature is lower than the freezing temperature at a temperature of -18 ° C. save. This can save a lot of energy. Further, the term "effective" means that the food can be conveyed in a subcooled state while being transported in a low-temperature transport vehicle as a refrigerator, and the supercooled state is maintained, and then the low-temperature cold air is directly supplied to the food, the supercooling is removed, and the cold storage is performed. In other words, in the case of meat, fish, etc., the cells and the cells are filled with water without a gap. Therefore, since the container is filled with water without a gap, the supercooling is not released by the vibration during transportation. Moreover, the room temperature food is stored and cooled at an extremely low temperature, and the final freezing temperature does not reach an extremely low temperature of -60 ° C as in a business refrigerator, whereby the freezing temperature of -20 ° C can be used as much as possible, so The energy of the truck is not used, and it is possible to use the transportation time to perform energy saving before and after the transportation such as cooling and freezing, so that a food having good freezing quality can be obtained. Further, in the refrigerator of the present invention, the cooling rate of the food which is subjected to the supercooling and freezing is slow in the production of the supercooled state, and therefore, after the temperature reaching the inside of the food is lowered in a uniform state, the ice crystals are simultaneously generated, and one part is produced. Ice crystals do not grow in a state of unevenness, and the size of ice crystals formed inside the food becomes small, and the quality of the food can be maintained. As for the relationship between the cooling rate and the size of the ice crystal inside the food, the faster the cooling rate, the larger the size of the ice crystal formed inside the food of 7042-9822-PF 56 200923296. The refrigerator of the present invention comprises a freezer compartment which can adjust the temperature of the received food from the temperature of the c°c to the temperature of the freezing temperature range by the cold air circulating by the cooler, and adopts the freezer compartment. The cold air blows out and sucks the cold air of the cooler, and maintains the food in an unfrozen supercooled state at a temperature lower than the freezing point, and is disposed in the cooling chamber in the freezing chamber, and the food stored in the cooling chamber is supercooled. The temperature setting device that sets the temperature of the freezer compartment to -2 ° C or less and -1 5 ° C or more, adjusts the wind speed around the food stored in the cooling chamber, and maintains the food stored in the cooling chamber in a supercooled state. The cold air conditioning device that blows the cold air into the freezer compartment and enters the cooling chamber can then achieve high quality freezing without energy. The refrigerator of the present invention includes a cooling chamber in which the stored food is maintained in an unfrozen supercooled state by a cold air from a cooler at a set temperature of -1 5 ° C or higher, and is blown to the supercooling chamber. The cold air adjusting device that changes the temperature of the cold air circulating in the indoor cooling chamber, and the cold air adjusting device stores the cold air which is stored in the supercooling chamber and is in a supercooled state at a temperature lower than the set temperature by 2 to 5 degrees. In the supercooled state, the supercooling release device can easily obtain a frozen food of good quality. In the temperature setting device for setting the temperature of the refrigerator or the cooling chamber of the present invention, when the room temperature food stored in the cooling chamber is cooled, the cooling rate of the surface temperature of the food falling from 3 ° C to 0 ° C is set to - 3. The range of 5 °C / hr to -1 0 °C / h, so it can be surely poured into the supercooled state. The cold air adjusting device 15 is provided, and the cold air is blown to the cold air blowing port which is the cooling chamber of the freezing chamber or the storage chamber of the present invention, and the cold air is introduced into the inlet of the 7042-9822-PF 57 200923296 room, the cold air blowing port and the cold air inlet. At least one of the air ducts adjusts the air-conditioning. By adjusting the air-conditioning by the air-conditioning adjustment, the wind speed around the food that becomes the supercooled state can be suppressed to Oi to 〇5 m/s, so that the supercooling state can be maintained. . The air-conditioning adjusting device 15 of the present invention, the air passage! 6 is configured to form a plurality of curved structures on the indirect cooling air passage 16B, or to provide a length of the air passage corresponding to the depth of the switching chamber as the cooling chamber of the storage compartment, or the cold air adjusting device by the collision plate 15A The wind speed of the cold air blowing port which is blown to the cold air chamber or the cooling chamber is suppressed to m·〇 to 2 m/s, whereby the supercooled state can be maintained. Further, in the present embodiment, the switching chamber 4 is taken as an example to describe the storage t which can be cooled, supercooled, cold-bundled, and rapidly cooled, but even if it is frozen to 6, vegetable room 5, etc. The storage room also includes the air duct for direct cooling and the air duct for indirect cooling. If the air duct can be switched, it can be supercooled and frozen = rapid freezing. In this way, it is possible to provide a good refrigerator or a storage which is easy for the user to use, regardless of the temperature range of the user's traitor == Huan's treasury, and the supercooled and frozen shape, regardless of the storage room.
