The cross section of Fig. 3 is the same as the cross section of Fig. 2, but the cross-sectional position is different, so 2l48-l〇239-PF; Ahddub u 200949179 exhibits different cross-sectional shapes. Fig. 5 is a side plan view showing the vicinity of a switching chamber of a refrigerator according to a second embodiment of the present invention. In Fig. 3 and Fig. 5, 31 is a damper for switching to indirect cooling and vegetable compartment. 31A is a first baffle for the switching chamber indirect cooling and the vegetable compartment damper 31. 31B is an opening for the vegetable compartment for the indirect cooling of the switching chamber and the damper for the vegetable compartment, and the vegetable compartment opening 3β is an inlet for introducing the cold air into the air passage (not shown) of the vegetable compartment 6.

When the first baffle 31A is fully opened, the vegetable compartment uses 2148-1023 9-PF/Ahddub 200949179 opening portion_closed so that cold air is not introduced into the vegetable compartment 6. Therefore, even when the indirect cooling is performed in the two chambers 4, the temperature of the vegetable compartment 6 is controlled in accordance with the set temperature. Of course, if the first baffle 31A is closed, there is no cold air flow into the vegetable compartment 6'; and the milk is transferred to the switching chamber indirect cooling air passage 6B. The fourth is not blocking the cry _M to ° The cost of having a motor is less than when using an individual motor. Fig. 6 is a block diagram showing the structure related to the control of the first embodiment of the present invention.

The hanging picture is the digital message. ... the operation of the control unit 71, which is switched to the refrigerator in the first known type of the present invention, and is switched to the direct switching chamber 2148-10239-pp in general freezing; Ahddub 200949179 - using a damper and a switching chamber The indirect cooling is related to the control of the vegetable compartment damper. The control unit 71 determines in step S1 that it is The operating condition of the compressor 丨2 is satisfied. The operating condition of the s gastric compressor 12 is that the temperature detected by the temperature detecting device 23 of the freezing chamber 5 is equal to or higher than a predetermined temperature, and is determined in step s丨. NO returns to step si. If the determination in step S1 is YES, the process proceeds to step S2. In step S2, the control unit 71 determines whether or not the switching chamber thermistor j 9 is equal to or higher than the predetermined temperature TO t. In step S2, it is determined that the switch is switched to the thermistor 19 at a predetermined temperature το. ,, and the process returns to step S2. If the control unit 71 determines in step S2 that the switch room thermistor 19 is at or above the predetermined temperature TO C, the process proceeds to Step S3: In step S3, the control unit 71 turns on the switching chamber direct cooling damper 21. After step S3, the control unit 71 proceeds to the step. The control unit 71 determines in step S4 whether or not the switching chamber thermistor 19 is in the predetermined state. The temperature is T1 ° C or less. If it is determined in step S4 that the switching chamber thermistor i Q is not below the predetermined temperature T1 ° C, the process returns to step S4. If it is determined in the step, the switch to the thermistor 19 is at the predetermined temperature τ. Below 1 °C, proceed to step s 5. The control unit 71 is closed square in step S5 the switch compartment 21. The direct cooling damper from step S2 to step S5 'to each other independent of each other, in step ", if the determination is YES, the process proceeds to step S6. In step 邡, the control unit 71 determines whether or not the vegetable room thermistor (not shown) is at or above the predetermined temperature T2t:. When it is judged in step S6 that the kitchen thermistor (not shown) is below the predetermined temperature τ 2 ^', the process returns to step S6. If it is determined in step S6 that the vegetable compartment thermistor (not shown) is at or above the predetermined temperature T 2 °C, the routine proceeds to step s7. The control unit 71 opens the switching chamber indirect cooling and the vegetable compartment damper 31 to a predetermined angle Θ 0 in step S7. After step S7' proceeds to step S8. Steps 2148-10239~PF; Ahddub 14 200949179 is old! Disconnect 4 dishes until the thermistor (not shown) is at a predetermined temperature Τ 3. Please follow the steps below. If it is determined in step S8 that the vegetable compartment thermistor (not shown) I is equal to or lower than the predetermined temperature T3 < t, the flow returns to step S8. If it is determined in step s8 that the kitchen thermistor (not shown) is below the predetermined temperature T3t:, the process proceeds to step S9. The control unit 71 turns off the switching chamber indirect cooling and the vegetable compartment damper 31 in step 39. ^

❹ In step S7, the switching chamber indirect cooling and the vegetable compartment damper 3ι are opened, so that the cooling duct can be connected to the switching chamber 4, but if the angle of the first jaw 31A is set to be small In addition, the wind speed of the cold air introduced into the top air outlet m is lowered, and the cold air passing through the switching chamber indirect cooling and the vegetable compartment damper 31 mostly flows into the opening portion 31B. Thus, the temperature influence applied to the switching chamber 4 is very small, so that the switching chamber 4 can be controlled only by the damper 直接 of the switching chamber direct cooling. According to the flowchart shown in Fig. 7, by switching the operation state of the chamber 4, the temperature can be controlled without being affected. Further, since the cold air of the damper 21 is directly blown into the switching chamber container 17 by the switching chamber, the switching chamber 4 is cooled, so that waste of power consumption of the shoulder of the refrigerator body 1 can be reduced. On the other hand, Fig. 8 is a flowchart showing the operation of the control unit 71. The first and second types of the refrigerator switching chamber 4 in the supercooling and freezing compartment are directly cooled by the damper 21 and switched. Indirect cooling of the room and a: and (4) 1 control. The so-called over-cooling means that the cold-sending mode is called "the so-called super-cooling state, which means that it is not in the state of the following:. Here, the so-called roll 2148-l〇239-PF; Ahddub 15 200949179 结 node ' refers to the temperature at which the substance begins to freeze. In other words, the supercooled state refers to a state in which it is not completely frozen at a temperature at which freezing should be started. For example, the freezing point of water is 〇 t:. This freezing point varies with different substances, and in foods with high salinity or sweetness, there is a tendency to be lower than 〇t:. Regarding the freezing in the supercooled state or the cooled state, if water is taken as an example, the supercooled state is a state in which, after the water is cooled, even if it is lower than the freezing point, it is still 100% water. The water in the supercooled state is also the same, as long as the knot is slightly smeared, it can become ice, but 'some kind of stimulation is needed at this time. This stimulus can be a temperature stimulus or a physical stimulus. Thus, the time required for the stimulus to cause the bead to begin to change but the state to begin to freeze is in seconds, and is instantaneous. However, #此; At the beginning of the East knot, the ratio of instantaneous frozen ice is a percentage of the total, and more cooling time is required before it becomes one hundred and two hundred. Knife Here, the difference between the normal freezing and the supercooling freezing is compared, and the description is made. First, the general; east knot and overcooling; the biggest difference of the east knot is the difference between entering the supercooled state and not entering the supercooled state. In the case of general ·, ^ ^, if it exceeds; East node, do not enter the person to cool (four) to open ^, Huiji ° Again, another - a general Kang Jie and supercooling Kang Jie is very different: The state at the beginning of the bead. In the case of Λ, the water in the bottle is taken as an example;;: What happens when there is no knot. In the case of general knots: When the freezing begins, the name is frozen from the water near the surface of the bottle, and part of it has a state of thin ice adhesion, then the ice expands toward the inside: Finally: all freeze. The growth of ice is based on the ice core. Among them, the ice core shape is 2l48-l〇239-PF; the Ahddub 16 200949179 water molecule is more than a certain size ^ a* ^ , the formation of ice nuclei is in Generated at the beginning of the freeze. Therefore, it can be said that in the case of the freezing of the female slave slave, the ice core on the surface is formed on the surface, and the ice is grown as part of the water state. ~~j

On the other hand, in the case of the cold name P; the golden gentleman AA, if the east is frozen, when the freezing starts, the ice core is formed in a uniform shape throughout the entire bottle. Then, all the parts inside the bottle containing the inner and the surface, 3 1 knife, the growth of the ice, so the ice ❿

Growth does not go in a certain direction. After the end of the freeze, the ship & is the difference between the east, the .σ and the supercooled bundle, from the difference of the cooling process, y·,. ^ ° brother in the case of general freezing, A large acicular ice junction is formed from the surface toward the inside. On the other hand, in the case of supercooling, crystals are formed in a uniform state on the surface and inside. In the case of rapid freezing, at the beginning of freezing and after the end of freezing, the cold air is brought into contact with the surface to cause rapid freezing, which is the same as the condition of the normally frozen state. First, the temperature of the surface drops rapidly, so it starts to roll from the surface. However, the difference from the general bead is that the speed of cooling to the inside is faster. The phase of n is easier to form the ice core than the inside of m, and ice crystals as large as normal freezing do not occur. Considering the use of food freezing, the size and shape of ice crystals after freezing are greatly affected by the quality of the food during thawing. In most cases, foods are composed of cells, proteins, sugars, etc. Therefore, most of them are destroyed by ice crystals, and most of them cannot be completely restored to their original state. Yu Yu, the size and shape of the ice crystal formed when frozen to the right will not destroy the food 2l48-l〇239-PF; Ahddub 200949179 original structure, it will achieve a good mouth-to-mouth quality. Next, the advantages and originality of freezing food by A's careful freezing and freezing are described. By overcooling and cooling; refreshing I, going to the frozen ', the biggest advantage of the mouthfuls is that it can achieve good quality cold; East. As described above, 丨曰&& 刖, as described above, during the freezing of the supercooled state, the process of supercooling makeup >, ai 1 ^ state allows the inside of the food to be sufficiently cooled, therefore, The whole food state forms an ice core and grows into small granular ice crystals. Further, the difference between the lowest temperature at which the supercooled state is reached and the difference between the nodes 越大 ’ is larger. The more the number of ice cores formed at the beginning of the knotting, the more the ice crystals are formed. Therefore, if the past eight ", the right cold can be fully generated (the lower the temperature reached the state of cooling), even if the mouth of the food has undergone a process from freezing to thawing, it can be maintained close to freezing. State. When considering the cooling and ice crystallization of foods, the size and shape of the ice crystals, it is a conventional practice to consider the passage time of the temperature band of -1 °C to 5.7 as the largest ice crystal formation zone. The idea is that the ice crystals can be made smaller by the maximum ice crystal formation zone in the short-term day. In the case of supercooling and freezing, the temperature band (-rc-iot: nearby) in the vicinity of the largest ice crystal generation zone is left, a, A, and is in a supercooled state for a long time. However, the so-called supercooled state refers to a state in which it has not been frozen. Therefore, if it is in a supercooled state, even if the temperature band is full and the spray 4 is long, the ice crystal after freezing does not become large, and fine ice red β, ,, crystal can be generated. By freezing in the vicinity of the temperature band containing the maximum ice crystallization temperature band, small particle ice crystals can be formed by π 1 J to achieve high quality freezing. According to this point, this ounce is a new freezing method. Also, when the supercooling state is released, 'Kunction starts, the temperature does not change, and then the phase changes state, and then completely smashes'. However, if it is cooled 2 2148-10239-PF; Ahddub 18 200949179 state, even later The freezing process stays in the maximum ice crystallization zone for a long time, and it is also determined that the ice crystals will not be enlarged. Therefore, according to this point, it can also be called a new cold; East method. ❹ ❹ If it is cooled, even if it takes a long time in the subsequent freezing process, it will hardly affect the ice crystal state. However, if it enters the rolling process, it will be cold and cold; the east down will further reduce the ice crystal hypertrophy. The possibility of chemical conversion can also avoid the main reason for the deterioration of food quality in addition to ice crystals, so that better quality freezing can be achieved. Further, although only the advantage of supercooling and releasing the food which has previously entered the supercooled state has been described, the food which has entered the supercooling state does not need to be washed. The advantage of maintaining the supercooled state is that, although it is at the temperature of the east junction, that is, at the temperature at which the knot will be rolled, it is in a state of freezing without freezing, and no ice crystal is formed at all. It can be preserved at low temperature and can be finished in the Eight Kings to avoid ice. The crystal structure of the food is changed by: Oral crystal: It can inhibit various chemical changes of food under the condition of lower temperature. According to this point, 'General knowledge It can effectively maintain the freshness, not correct. This can also be said to be a preservation method for the advantages of low dish preservation and non-beading. Also, there is no need to solve the food. However, going and thawing have their shortcomings. If the water in the mouth is not frozen, the bacteria will be mutated, and various chemical changes may be beneficial. Therefore, because of this point, compared to the "knot of the knot, that is, if you want to achieve over-cooling; to be more note ο, Α φ you 7 / Dong flat to cool the food in the state - the mouth - the method is to carry out Indirect cooling Next, the flow chart of Fig. 8 will be described. At the beginning of step (4), as the starting point of the main overcooling die cold mode, the display surface 2148-10239-PF is set; Ahddub 200949179 ❹ plate And a switch (not shown), these devices are operated by the user to start the supercooling mode. After the step, the control unit first closes the switching chamber direct cooling damper 21 in the step "Μ". In such an action, the cooling and freezing are achieved, and the cold air is prevented from being directly blown into the inside of the switching chamber 4, whereby the food inside the switching chamber 4 is cooled in a uniform state. After the step S1 〇 2, the process proceeds to a step S1 03 of judging whether or not the compressor 12 is in operation. If it is judged in step 03 that the compressor 12 is in the stop (no), the process returns to step S1 〇2. If it is determined in step S103 that the compressor 12 is in operation (YES), the process proceeds to step 4 control. In step S1 0 4, P 71 determines whether or not the detection result of the vegetable compartment thermistor 2 3 is equal to or higher than a predetermined temperature T 〇 t . If it is determined in step s丨〇 4 that the detection result of Zhao Cai to the thermistor 2 3 is not at the predetermined temperature τ 〇. 〇

Above (N0), proceed to step sl6. In step (10), the control unit 71 controls the damper motor drive unit 75 to indirectly cool the switching chamber and open the vegetable compartment damper 31 to a predetermined angle 011. The so-called 0 ι means that when it is a degree, the switch is switched to indirect cooling. The opening of the damper of the vegetable room is closed by the first board 31. Therefore, there is no cold airflow into the vegetable compartment 6, and unnecessary cooling is not performed. In step sm, if it is judged that the detection result of the vegetable to the thermistor benefit 23 is equal to or higher than the predetermined temperature T1 〇 i (YES), the process proceeds to step sl5. In step si〇5, the control unit 71 controls the damper motor drive unit 75 to indirectly cool the switching chamber and the vegetable compartment damper. Open to the established angle "〇. The so-called squeaking means that when it is 45 degrees, the opening portion 31 B is not closed by switching to the baffle WA of the indirect cold portion and the vegetable compartment damper, so that the cold air is blown into the vegetable compartment 6. Therefore, in step S104, regardless of the judgment, the cooling of the vegetable compartment 6 is lower than that of the switching chamber 4 2148-10239-PF; Ahddub 20 .200949179

Can be controlled independently. After step S105 and step si (10), the control unit 71 proceeds to step S101 to determine whether the detection result of the switching chamber thermistor 19 is equal to or less than Tirc in step S10". If the switching chamber heat is judged in step §1〇7 The detection result of the varistor 19 is 711 〇 or more (n〇), and returns to the step sm. If the switching chamber thermistor is judged in the step S7, the double measurement result is below the Tire (YES), and proceeds to Step S108: The control unit 71 controls the damper motor driving device 75 in the step S108, and opens the switching chamber to directly cool the damper damper 2 by step (4) 〇8, so that the cold air directly flows into the switching chamber 4, Dong Shi The food inside the switching chamber 4 is stimulated, thereby achieving overcooling. In addition, the predetermined temperature tikc is mainly the freezing point of the meat, about _5 C or so, and the freezing point is not limited to this value. The size and shape of the meat vary, for example, the pork chops of about 1 〇〇 can be made into a 100% beaded state to achieve a high-quality frozen state. The second embodiment.
