Description

refrigerator

本發明係有關於一種冰箱，該冰箱係具備被設定於軟冷凍溫度帶的貯藏室。The present invention relates to a refrigerator equipped with a storage compartment set in a soft freezing temperature zone.

在以往之冰箱所進行之一般的冷凍，係從食品之表面往中心逐漸地產生針狀的結晶。因此，出現食品之細胞被破壞所造成之解凍後之口感的惡化及鮮味成分的流失之對食品之品質的影響。因此，提議一種進行提高冷凍品質之冷凍的冰箱(例如，參照專利文獻1)。The general freezing in conventional refrigerators gradually produces needle-shaped crystals from the surface of the food to the center. Therefore, the deterioration of the taste after thawing and the loss of umami components caused by the destruction of the cells of the food will affect the quality of the food. Therefore, a refrigerator that performs freezing with improved freezing quality is proposed (for example, refer to Patent Document 1).

在專利文獻1之冷凍，係在食品被投入冰箱內並門被關閉後，一度將食品導入在結凍溫度以下亦不結凍之過冷卻狀態，再對被導入過冷卻狀態之食品給與物理性或溫度性的刺激。此處，過冷卻狀態係意指食品被冷卻至食品之結凍溫度以下亦成為未結凍的狀態。藉由依此方式，解除過冷卻狀態，而食品急速地進行結凍。依此方式已進行結凍的食品係因為在食品整體形成冰核，並可均勻地產生微粒子的冰結晶，而抑制食品之細胞破壞，並抑制解凍後之口感的惡化。亦維持鮮味成分，所以進行結凍亦可高品質地保存食品。 [先行專利文獻] [專利文獻]The freezing in Patent Document 1 refers to the fact that after the food is put into the refrigerator and the door is closed, the food is once brought into a supercooled state below the freezing temperature without freezing, and then the food introduced into the supercooled state is given physical Sexual or temperature stimulation. Here, the super-cooled state means that the food is cooled to below the freezing temperature of the food and becomes an unfrozen state. In this way, the over-cooling state is released, and the food freezes rapidly. In the food that has been frozen in this way, ice cores are formed in the whole food, and ice crystals of fine particles can be uniformly produced, thereby inhibiting the destruction of food cells and inhibiting the deterioration of the taste after thawing. It also maintains umami ingredients, so it can preserve food with high quality by freezing. [Prior Patent Document] [Patent Literature]

[發明所欲解決之課題][The problem to be solved by the invention]

要在被設定於軟冷凍溫度帶(例如，約－7℃)的貯藏室在將食品確實地導入過冷卻狀態後進行結凍，係需要在食品被投入冰箱內並門被關閉後，一度使冰箱內溫度上升至食品之結凍溫度的附近，然後，為了促進食品之結凍，使冰箱內溫度成為食品之結凍溫度以下的溫度。可是，在如專利文獻1之以往的冰箱，係在食品被投入冰箱內並門被關閉後，在未使冰箱內溫度上升至食品之結凍溫度的附近下成為結凍溫度以下的溫度。因此，有時在食品仍然未被導入過冷卻狀態下就結凍了，而具有無法高品質地保存食品的課題。To freeze the food in a storage room set at a soft-freezing temperature zone (for example, about -7°C), the food must be put into the refrigerator and the door is closed. The temperature in the refrigerator rises to the vicinity of the freezing temperature of the food, and then, in order to promote the freezing of the food, the temperature in the refrigerator is made to be below the freezing temperature of the food. However, in a conventional refrigerator such as Patent Document 1, after the food is put into the refrigerator and the door is closed, the temperature in the refrigerator becomes a temperature below the freezing temperature of the food without raising the temperature in the refrigerator to the vicinity of the freezing temperature of the food. Therefore, the food may freeze even when the food has not been introduced into the supercooled state, and there is a problem that the food cannot be preserved with high quality.

本發明係為了解決如以上所示之課題所開發者，其目的在於提供一種可高精度並高品質地保存食品的冰箱。 [解決課題之手段]The present invention was developed to solve the problems described above, and its object is to provide a refrigerator that can store foods with high precision and high quality. [Means to solve the problem]

[Effects of Invention]

若依據本發明之冰箱，在將被設定於軟冷凍溫度帶之第一貯藏室的冰箱內溫度維持於平常設定溫度的平常溫度控制中，偵測到門之開閉的情況，係進行特殊溫度控制，而該特殊溫度控制係將第一貯藏室之冰箱內溫度以比平常設定溫度更高的第一設定溫度維持第一時間後，以比平常設定溫度更低的第二設定溫度維持第二時間。因此，即使是食品被投入冰箱內並門被關閉後，亦可在將食品更確實地導入過冷卻狀態後進行結凍，而可高精度並高品質地保存食品。According to the refrigerator of the present invention, in the normal temperature control that maintains the temperature in the refrigerator in the first storage compartment of the soft freezing temperature zone at the normal set temperature, the opening and closing of the door is detected, and special temperature control is performed , And the special temperature control system maintains the temperature in the refrigerator in the first storage compartment at a first set temperature higher than the normal set temperature for the first time, and then maintains it at a second set temperature lower than the normal set temperature for a second time . Therefore, even after the food is put into the refrigerator and the door is closed, the food can be frozen after being brought into the supercooled state more reliably, and the food can be preserved with high precision and high quality.

其次，說明藉切換被設定於軟冷凍溫度帶(－7℃)的切換室200之冰箱內溫度的控制。Next, the control of the temperature in the refrigerator in the switching chamber 200 set in the soft freezing temperature zone (-7°C) by switching will be described.

圖3係表示本發明之實施形態1的冰箱1之在平常溫度控制中進行切換室門12的開閉時之切換室200的冰箱內溫度之時間變遷的圖。首先，說明在平常溫度控制中進行切換室門12的開閉時之切換室200之冰箱內溫度的控制。此處，平常溫度控制係將切換室200之冰箱內溫度維持於平常設定溫度(例如，約－7℃)的控制。又，切換室門12的開閉係切換室門12從被打開的狀態被關閉。FIG. 3 is a diagram showing the time transition of the temperature in the refrigerator in the switching chamber 200 when the switching chamber door 12 is opened and closed in the normal temperature control of the refrigerator 1 according to the first embodiment of the present invention. First, the control of the temperature in the refrigerator in the switching chamber 200 when the switching chamber door 12 is opened and closed in the normal temperature control will be described. Here, the normal temperature control is a control that maintains the temperature in the refrigerator in the switching chamber 200 at a normal set temperature (for example, about −7° C.). In addition, the opening and closing of the switching chamber door 12 is that the switching chamber door 12 is closed from the opened state.

控制裝置50係在平常溫度控制中偵測到切換室門12之開閉的情況，使切換室200之冰箱內溫度移至比在切換室門12無開閉的情況所設定之平常設定溫度更高的第一設定溫度(例如，約－4℃)。而且，在移至第一設定溫度後，維持於第一設定溫度第一時間(例如，約一個半小時)。然後，控制裝置50係使切換室200之冰箱內溫度移至比平常設定溫度更低的第二設定溫度(例如，約－12℃)。而且，在移至第二設定溫度後，維持於第二設定溫度第二時間(例如，約2小時)。此處，關於從第一設定溫度往第二設定溫度之轉移，從第一設定溫度至平常設定溫度的轉移係花約2.5小時所進行。即，此期間係切換室200之冰箱內被逐漸地冷卻。而，從平常設定溫度至第二設定溫度的轉移係花約10分鐘所進行。即，此期間係切換室200之冰箱內被急速地冷卻。然後，控制裝置50係維持於平常設定溫度至偵測到切換室門12的開閉。The control device 50 detects the opening and closing of the switching chamber door 12 during normal temperature control, and moves the temperature in the refrigerator in the switching chamber 200 to a higher temperature than the normal setting temperature set when the switching chamber door 12 is not opened or closed. The first set temperature (for example, about -4°C). Moreover, after moving to the first set temperature, it is maintained at the first set temperature for the first time (for example, about one and a half hours). Then, the control device 50 moves the temperature in the refrigerator in the switching chamber 200 to a second set temperature (for example, about -12° C.) that is lower than the usual set temperature. And, after moving to the second set temperature, it is maintained at the second set temperature for a second time (for example, about 2 hours). Here, regarding the transition from the first set temperature to the second set temperature, the transition from the first set temperature to the normal set temperature takes about 2.5 hours. That is, during this period, the inside of the refrigerator in the switching chamber 200 is gradually cooled. However, the transition from the usual set temperature to the second set temperature took about 10 minutes. That is, during this period, the inside of the refrigerator in the switching chamber 200 is rapidly cooled. Then, the control device 50 maintains the normal set temperature until the opening and closing of the switching chamber door 12 is detected.

依此方式，控制裝置50係在偵測到切換室門12之開閉的情況，進行特殊溫度控制，該特殊溫度控制係將切換室200之冰箱內溫度維持於第一設定溫度第一時間後，維持於第二設定溫度第二時間。此處，平常設定溫度、第一設定溫度以及第二設定溫度係分別是0℃以下的冷凍溫度帶。又，第一設定溫度係採用比平常設定溫度之追逐寬度的上限高，並成為食品之開始結凍溫度以上的－5℃~0℃之間的溫度。又，第二設定溫度係採用比平常設定溫度之追逐寬度的下限低的溫度。In this way, the control device 50 performs a special temperature control upon detecting the opening and closing of the switching chamber door 12, and the special temperature control is to maintain the temperature in the refrigerator in the switching chamber 200 at the first set temperature for the first time, Maintain at the second set temperature for a second time. Here, the normal set temperature, the first set temperature, and the second set temperature are each a freezing temperature zone of 0°C or less. In addition, the first set temperature is higher than the upper limit of the chase width of the usual set temperature, and becomes a temperature between -5°C and 0°C above the freezing temperature of the food. In addition, the second set temperature is a temperature lower than the lower limit of the chase width of the usual set temperature.

控制裝置50係偵測到切換室門12的開閉時進行特殊溫度控制，藉此，可配合以與切換室門12之開閉連動的方式所進行之食品的投入，使特殊溫度控制開始。因此，因為食品係在剛投入後在第一設定溫度被保存，所以比在平常設定溫度被保存的情況更緩慢地被冷卻。又，尤其藉由在成為開始結凍溫度以上之－5℃~0℃之間保存食品，可將食品高精度地導入過冷卻狀態。此處，過冷卻狀態係意指食品被冷卻至食品之結凍溫度以下亦成為未結凍的狀態。The control device 50 performs special temperature control when detecting the opening and closing of the switching chamber door 12, and thereby, can cooperate with the input of food in a manner linked with the opening and closing of the switching chamber door 12 to start the special temperature control. Therefore, since the food system is stored at the first set temperature immediately after being put in, it is cooled more slowly than when it is stored at the usual set temperature. Moreover, especially by storing the food between -5°C and 0°C which is higher than the freezing temperature, the food can be brought into the supercooled state with high accuracy. Here, the super-cooled state means that the food is cooled to below the freezing temperature of the food and becomes an unfrozen state.

又，藉由將食品保存於第一設定溫度第一時間後在第二設定溫度保存，解除食品之過冷卻狀態，且開始結凍後係比在平常設定溫度保存的情況更急速地冷卻食品。依此方式，藉由將食品導入過冷卻狀態後進行結凍而形成均勻的結冰，且藉由在開始結凍後急速地冷卻食品而可抑制冰結晶擴大。結果，可抑制結凍所引起之食品之細胞被破壞所造成之解凍後之口感的惡化、及鮮味成分的流失之對食品之品質的影響。即，因為抑制食品之細胞的破壞、可抑制解凍後之口感的惡化、鮮味成分亦被維持，所以進行結凍亦可高品質地保存食品。In addition, by storing the food at the first set temperature for the first time and then at the second set temperature, the supercooled state of the food is released, and after freezing starts, the food is cooled more quickly than when stored at the normal set temperature. In this way, the food is introduced into the supercooled state and then frozen to form uniform icing, and the expansion of ice crystals can be suppressed by rapidly cooling the food after the freezing starts. As a result, it is possible to suppress the influence of the deterioration of the taste after thawing and the loss of umami components on the quality of the food caused by the destruction of the cells of the food caused by freezing. That is, since the destruction of the cells of the food is suppressed, the deterioration of the taste after thawing can be suppressed, and the umami components are also maintained. Therefore, the food can be preserved with high quality by freezing.

又，因為使用者在投入食品後不必以設定操作部10輸入已投入食品，控制裝置50係偵測到切換室門12的開閉時自動地使特殊溫度控制開始，所以可在不費人力與時間下高品質地保存食品。又，可防止因使用者在投入食品後忘了以設定操作部10輸入已投入食品而在投入食品後未進行特殊溫度控制的事情。In addition, since the user does not need to input the inputted food with the setting operation unit 10 after putting in the food, the control device 50 automatically starts the special temperature control when it detects the opening and closing of the switching chamber door 12, so it can save labor and time. Preserve food with high quality. In addition, it can be prevented that the user forgets to input the input food with the setting operation unit 10 after inputting the food, and the special temperature control is not performed after the input of the food.

又，關於從第一設定溫度往第二設定溫度之轉移，藉由從第一設定溫度至平常設定溫度係逐漸地冷卻冰箱內，抑制冰箱內之食品的溫度變動。因此，在鷄肉等之難被導入過冷卻狀態的食材，亦可更穩定地向過冷卻狀態導入。又，藉由從平常設定溫度至第二設定溫度係將冰箱內急速地冷卻，冰箱內之食品的溫度變動變大。因此，在過冷卻狀態難被解除，即結凍難結束的乳製品等之脂質高的食材亦可確實地解除過冷卻狀態。In addition, regarding the transition from the first set temperature to the second set temperature, by gradually cooling the inside of the refrigerator from the first set temperature to the normal set temperature, the temperature fluctuation of the food in the refrigerator is suppressed. Therefore, food materials that are difficult to be introduced into the supercooled state, such as chicken, can also be introduced into the supercooled state more stably. In addition, by rapidly cooling the inside of the refrigerator from the normal set temperature to the second set temperature, the temperature fluctuation of the food in the refrigerator increases. Therefore, it is difficult to be released in the supercooled state, that is, foods with high lipids such as dairy products that are difficult to freeze can be reliably released from the supercooled state.

此外，第一時間及第二時間係以一次之特殊溫度控制中的平均溫度成為與平常設定溫度相同的方式決定即可。藉由依此方式決定，在重複特殊溫度控制的情況，亦因為平均溫度成為平常設定溫度，所以可保持與冰箱內溫度具有相關關係之食品的保存期間。In addition, the first time and the second time may be determined such that the average temperature in one special temperature control becomes the same as the normal set temperature. By determining in this way, when the special temperature control is repeated, the average temperature becomes the usual set temperature, so the storage period of the food that has a correlation with the temperature in the refrigerator can be maintained.

圖4係表示本發明之實施形態1的冰箱1之在特殊溫度控制中進行切換室門12的開閉時之切換室200的冰箱內溫度之時間變遷的圖。其次，說明在特殊溫度控制中進行切換室門12的開閉時之切換室200之冰箱內溫度的控制。4 is a diagram showing the time transition of the temperature in the refrigerator in the switching chamber 200 when the switching chamber door 12 is opened and closed in the special temperature control of the refrigerator 1 according to the first embodiment of the present invention. Next, the control of the temperature in the refrigerator in the switching chamber 200 when the switching chamber door 12 is opened and closed in the special temperature control will be described.

控制裝置50係在特殊溫度控制中偵測到切換室門12之開閉的情況，使特殊溫度控制從最初重新開始。即，控制裝置50係使切換室200之冰箱內溫度從那時之溫度移至第一設定溫度，在移至第一設定溫度後，維持第一時間。接著，控制裝置50係使切換室200之冰箱內溫度移至第二設定溫度，在移至第二設定溫度後，維持第二時間。然後，控制裝置50係將切換室200之冰箱內溫度維持於平常設定溫度至偵測到切換室門12的開閉。The control device 50 detects the opening and closing of the switching chamber door 12 during the special temperature control, so that the special temperature control is restarted from the beginning. That is, the control device 50 moves the temperature in the refrigerator in the switching chamber 200 from the temperature at that time to the first set temperature, and maintains it for the first time after moving to the first set temperature. Next, the control device 50 moves the temperature in the refrigerator in the switching chamber 200 to the second set temperature, and maintains it for the second time after moving to the second set temperature. Then, the control device 50 maintains the temperature in the refrigerator in the switching chamber 200 at the usual set temperature until the opening and closing of the switching chamber door 12 is detected.

此外，控制裝置50係在已從最初重新開始之特殊溫度控制中偵測到切換室門12之開閉的情況，使特殊溫度控制再從最初重新開始。In addition, the control device 50 detects the opening and closing of the switching chamber door 12 during the special temperature control that has been restarted from the beginning, so that the special temperature control is restarted from the beginning.

依此方式，控制裝置50係在特殊溫度控制中偵測到切換室門12之開閉的情況，使特殊溫度控制從最初重新開始。藉由依此方式，因為可將食品更確實地導入過冷卻狀態，所以在食品被追加投入的情況，亦可高精度並高品質地保存食品。In this way, the control device 50 detects the opening and closing of the switching chamber door 12 during the special temperature control, so that the special temperature control is restarted from the beginning. By this method, since the food can be brought into the supercooled state more reliably, it is also possible to store the food with high precision and high quality when the food is added.

此外，亦可為了一次之特殊溫度控制的平均溫度成為與平常設定溫度相同，在發生了特殊溫度控制之從最初重新開始的情況，從原本所設定之值改變第一時間及第二時間。即，亦可控制裝置50係在發生了特殊溫度控制之從最初重新開始的情況，為了一次之特殊溫度控制的平均溫度成為與平常設定溫度相同，從未發生特殊溫度控制之從最初重新開始的情況的值變更第一時間及第二時間。藉由依此方式，在重複特殊溫度控制的情況，亦因為平均溫度成為平常設定溫度，所以可保持與冰箱內溫度具有相關關係之食品的保存期間。In addition, it is also possible to change the first time and the second time from the originally set value in order that the average temperature of the one-time special temperature control becomes the same as the usual set temperature. That is, the control device 50 may restart from the beginning when the special temperature control occurs, so that the average temperature of the special temperature control once becomes the same as the normal set temperature, and the special temperature control has never been restarted from the beginning. The value of the situation changes the first time and the second time. In this way, even when the special temperature control is repeated, the average temperature becomes the usual set temperature, so the storage period of the food that has a correlation with the temperature in the refrigerator can be maintained.

又，在藉切換被設定於軟冷凍溫度帶之切換室200的上方，配置被設定於冷藏溫度帶的冷藏室100，並在切換室200的下方，配置被設定於冷藏溫度帶的蔬菜室400。In addition, above the switching chamber 200 set in the soft freezing temperature zone by switching, the refrigerating chamber 100 set in the refrigerating temperature zone is arranged, and below the switching chamber 200, the vegetable room 400 set in the refrigerating temperature zone is arranged .

此處，在若切換室200被設定於比平常設定溫度更低之溫度的貯藏室包圍的情況，係被周圍之貯藏室吸熱。因此，為了將切換室200之冰箱內溫度維持於平常設定溫度以上的第一設定溫度，係具有新需要輸入熱的裝置等之元件的可能性。因此，在與切換室200鄰接之上下位置配置被設定於是第一設定溫度以上之冷藏溫度帶的貯藏室。藉由依此方式，因為從切換室200之頂面及底面被輸入熱，所以不新追加輸入熱的裝置等，而僅藉擋板裝置17之開度的控制可將切換室200之冰箱內溫度維持於第一設定溫度。此外，將被設定於是第一設定溫度以上之冷藏溫度帶的貯藏室僅配置於與切換室200鄰接之上下位置的一方，亦可得到與上述相同之效果，但是配置於雙方可得到更大之效果。Here, if the switching room 200 is surrounded by a storage room set at a temperature lower than the usual set temperature, the heat is absorbed by the surrounding storage room. Therefore, in order to maintain the temperature in the refrigerator in the switching chamber 200 at the first set temperature higher than the usual set temperature, there is a possibility of new elements such as devices that require heat input. Therefore, a storage room set at a refrigerating temperature zone that is equal to or higher than the first set temperature is arranged at upper and lower positions adjacent to the switching room 200. In this way, because heat is input from the top and bottom surfaces of the switching chamber 200, no new heat input devices are added, and the temperature in the refrigerator in the switching chamber 200 can be controlled only by controlling the opening of the baffle device 17 Maintain at the first set temperature. In addition, the storage room set at the refrigerating temperature zone above the first set temperature can be arranged only on the side adjacent to the upper and lower positions of the switching room 200, and the same effect as the above can be obtained, but the arrangement on both sides can achieve larger effect.

以上，本實施形態1之冰箱1係包括：隔熱箱體2，係在內部形成包含被設定於軟冷凍溫度帶之切換室200的複數個貯藏室；及切換室門12，係開閉在切換室200之前面所形成的開口部。又，包括：門開閉偵測部19，係偵測切換室門12的開閉；溫度偵測部16，係偵測切換室200的溫度；溫度控制手段，係控制切換室200的溫度；以及控制裝置50，係根據溫度偵測部16之偵測溫度，控制溫度控制手段。而且，控制裝置50係在將切換室200之冰箱內溫度維持於預設之平常設定溫度的平常溫度控制中，偵測到切換室門12之開閉的情況，係進行特殊溫度控制，而該特殊溫度控制係使切換室200之冰箱內溫度移至比平常設定溫度更高的第一設定溫度並維持第一時間後，移至比平常設定溫度更低的第二設定溫度並維持第二時間。As described above, the refrigerator 1 of the first embodiment includes: a heat-insulating box 2 in which a plurality of storage rooms including a switching room 200 set in a soft freezing temperature zone are formed; and a switching room door 12 that is opened and closed during switching An opening formed on the front surface of the chamber 200. It also includes: a door opening and closing detection unit 19, which detects the opening and closing of the switching chamber door 12; a temperature detection unit 16, which detects the temperature of the switching chamber 200; a temperature control means, which controls the temperature of the switching chamber 200; and control The device 50 controls the temperature control means based on the temperature detected by the temperature detecting part 16. In addition, the control device 50 detects the opening and closing of the switching chamber door 12 in the normal temperature control that maintains the temperature in the refrigerator in the switching chamber 200 at a preset normal set temperature, and performs special temperature control. The temperature control system moves the temperature in the refrigerator in the switching chamber 200 to a first set temperature higher than a normal set temperature and maintains it for the first time, and then moves to a second set temperature lower than the normal set temperature and maintains it for a second time.

若依據本實施形態1之冰箱1，在將被設定於軟冷凍溫度帶之切換室200的冰箱內溫度維持於平常設定溫度的平常溫度控制中，偵測到切換室門12之開閉的情況，係進行特殊溫度控制，而該特殊溫度控制係將切換室200之冰箱內溫度以比平常設定溫度更高的第一設定溫度維持第一時間後，以比平常設定溫度更低的第二設定溫度維持第二時間。因此，可將食品更確實地導入過冷卻狀態後進行結凍，所以可高精度並高品質地保存食品。According to the refrigerator 1 of the first embodiment, the opening and closing of the switching chamber door 12 is detected in the normal temperature control that maintains the temperature in the refrigerator in the switching chamber 200 set in the soft-freezing temperature zone at the usual set temperature. The special temperature control is to maintain the temperature in the refrigerator in the switching chamber 200 at a first set temperature higher than the usual set temperature for the first time, and then to a second set temperature lower than the usual set temperature Maintain the second time. Therefore, the food can be brought into the supercooled state more reliably and then frozen, so the food can be preserved with high precision and high quality.

又，在本實施形態1之冰箱1，控制裝置50係在特殊溫度控制中偵測到切換室門12之開閉的情況，係使特殊溫度控制從最初重新開始。In addition, in the refrigerator 1 of the first embodiment, the control device 50 detects the opening and closing of the switching chamber door 12 during the special temperature control, so that the special temperature control is restarted from the beginning.

若依據本實施形態1之冰箱1，在特殊溫度控制中偵測到切換室門12之開閉的情況，係使特殊溫度控制從最初重新開始。因此，因為可將食品更確實地導入過冷卻狀態，所以在食品被追加投入的情況，亦可高精度並高品質地保存食品。If the refrigerator 1 according to the first embodiment detects the opening and closing of the door 12 during the special temperature control, the special temperature control is restarted from the beginning. Therefore, since the food can be brought into the supercooled state more reliably, it is also possible to store the food with high precision and high quality when the food is added.

又，在本實施形態1之冰箱1，控制裝置50係在特殊溫度控制中之從第一設定溫度往第二設定溫度的轉移，使從第一設定溫度至平常設定溫度的轉移比從平常設定溫度至第二設定溫度的轉移更花時間。In addition, in the refrigerator 1 of the first embodiment, the control device 50 shifts from the first set temperature to the second set temperature in the special temperature control, so that the transition from the first set temperature to the normal set temperature is greater than the normal set temperature. The transfer of the temperature to the second set temperature takes more time.

若依據本實施形態1之冰箱1，因為在從第一設定溫度至平常設定溫度係逐漸地冷卻冰箱內，所以抑制冰箱內之食品的溫度變動。因此，在鷄肉等之難被導入過冷卻狀態的食材，亦可更穩定地向過冷卻狀態導入。又，因為在從平常設定溫度至第二設定溫度係將冰箱內急速地冷卻，所以冰箱內之食品的溫度變動變大。因此，在過冷卻狀態難被解除，即結凍難結束的乳製品等之脂質高的食材亦可確實地解除過冷卻狀態。According to the refrigerator 1 of the first embodiment, since the inside of the refrigerator is gradually cooled from the first set temperature to the normal set temperature, the temperature fluctuation of the food in the refrigerator is suppressed. Therefore, food materials that are difficult to be introduced into the supercooled state, such as chicken, can also be introduced into the supercooled state more stably. In addition, since the inside of the refrigerator is rapidly cooled from the normal set temperature to the second set temperature, the temperature fluctuation of the food in the refrigerator becomes larger. Therefore, it is difficult to be released in the supercooled state, that is, foods with high lipids such as dairy products that are difficult to freeze can be reliably released from the supercooled state.

又，在本實施形態1之冰箱1，第一時間及第二時間係以一次之特殊溫度控制的平均溫度成為與平常設定溫度相同的方式所決定。In addition, in the refrigerator 1 of the first embodiment, the first time and the second time are determined so that the average temperature of one special temperature control becomes the same as the normal set temperature.

若依據本實施形態1之冰箱1，因為在重複特殊溫度控制的情況，亦因為平均溫度成為平常設定溫度，所以可保持與冰箱內溫度具有相關關係之食品的保存期間。According to the refrigerator 1 of the first embodiment, since the special temperature control is repeated, and the average temperature becomes the usual set temperature, the storage period of foods related to the temperature in the refrigerator can be maintained.

又，在本實施形態1之冰箱1，與切換室200鄰接的貯藏室之至少一個的冰箱內溫度被設定於冷藏溫度帶。或者，在切換室200的上方配置被設定於冷藏溫度帶的冷藏室100，並在切換室200的下方配置被設定於冷藏溫度帶的蔬菜室400。In addition, in the refrigerator 1 of the first embodiment, the temperature in the refrigerator of at least one of the storage rooms adjacent to the switching room 200 is set in the refrigerating temperature zone. Alternatively, the refrigerating room 100 set in the refrigerating temperature zone is arranged above the switching room 200, and the vegetable room 400 set in the refrigerating temperature zone is arranged below the switching room 200.

若依據本實施形態1之冰箱1，在與切換室200鄰接之位置配置被設定於是第一設定溫度以上之冷藏溫度帶的貯藏室。因此，藉從切換室200之頂面及底面所輸入的熱，不新追加輸入熱的裝置等，而僅藉擋板裝置17之開度的控制可將切換室200之冰箱內溫度保持於第一設定溫度。實施形態2According to the refrigerator 1 of the first embodiment, a storage room set at a refrigerating temperature zone set at a temperature equal to or higher than the first set temperature is arranged adjacent to the switching room 200. Therefore, with the heat input from the top and bottom surfaces of the switching chamber 200, no new heat input devices are added, and only the opening of the baffle device 17 can be controlled to keep the temperature in the refrigerator in the switching chamber 200 at the first A set temperature. Embodiment 2

以下，說明本發明之實施形態2，但是關於與實施形態1重複者係省略說明，並對與實施形態1相同的部分或相當的部分係附加相同的符號。此外，在本實施形態2，係在特殊溫度控制中進行了冰箱1之切換室門12的開閉時的溫度控制與實施形態1相異。Hereinafter, the second embodiment of the present invention will be described, but the description of those overlapping with the first embodiment will be omitted, and the same or equivalent parts as in the first embodiment will be given the same reference numerals. In addition, in the second embodiment, the temperature control when the switching chamber door 12 of the refrigerator 1 is opened and closed in the special temperature control is different from that in the first embodiment.

圖5係表示本發明之實施形態2的冰箱1之在特殊溫度控制中之第一設定溫度維持中進行切換室門12的開閉時之切換室200的冰箱內溫度之時間變遷的圖。以下，說明在特殊溫度控制中之第一設定溫度維持中進行了切換室門12的開閉時之切換室200之冰箱內溫度的控制。5 is a diagram showing the time transition of the temperature in the refrigerator in the switching chamber 200 when the switching chamber door 12 is opened and closed during the first set temperature maintenance in the special temperature control of the refrigerator 1 of the second embodiment of the present invention. The following describes the control of the temperature in the refrigerator in the switching chamber 200 when the switching chamber door 12 is opened and closed during the first set temperature maintenance in the special temperature control.

控制裝置50係在是在特殊溫度控制中偵測到切換室門12之開閉的情況，並將切換室200之冰箱內溫度維持於第一設定溫度的情況，係使特殊溫度控制不從最初重新開始而仍然繼續。而且，控制裝置50係將切換室200之冰箱內溫度以第一設定溫度維持第一時間。接著，控制裝置50係使切換室200之冰箱內溫度移至第二設定溫度，在移至第二設定溫度後，維持第二時間。然後，控制裝置50係將切換室200之冰箱內溫度維持於平常設定溫度至偵測到切換室門12之開閉。The control device 50 detects the opening and closing of the switching chamber door 12 during the special temperature control, and maintains the temperature in the refrigerator in the switching chamber 200 at the first set temperature, so that the special temperature control is not reset from the beginning. Start and continue. Moreover, the control device 50 maintains the temperature in the refrigerator in the switching chamber 200 at the first set temperature for the first time. Next, the control device 50 moves the temperature in the refrigerator in the switching chamber 200 to the second set temperature, and maintains it for the second time after moving to the second set temperature. Then, the control device 50 maintains the temperature in the refrigerator in the switching chamber 200 at the usual set temperature until the opening and closing of the switching chamber door 12 is detected.

依此方式，控制裝置50係在是在特殊溫度控制中偵測到切換室門12之開閉的情況，並將切換室200之冰箱內溫度維持於第一設定溫度的情況，係使特殊溫度控制不從最初重新開始而仍然繼續。在切換室200之冰箱內溫度被維持於第一設定溫度時食品被追加投入的情況，係因為食品被緩慢地冷卻，所以食品被導入過冷卻狀態的可能性高。即，不使特殊溫度控制從最初重新開始亦可高品質地保存食品，而可抑制使特殊溫度控制從最初重新開始之第一設定溫度的維持時間。結果，可縮短切換室200之冰箱內溫度成為比平常設定溫度更高之狀態的時間。藉此，不會降低將食品導入過冷卻狀態之食品之高品質保存的精度，且可抑制切換室200之冰箱內溫度的上升所造成之對既有食品之高品質保存的影響。In this way, the control device 50 detects the opening and closing of the switching chamber door 12 during the special temperature control, and maintains the temperature in the refrigerator in the switching chamber 200 at the first set temperature, so that the special temperature control Continue without restarting from the beginning. When the temperature in the refrigerator in the switching compartment 200 is maintained at the first set temperature, the food is added to the food, because the food is slowly cooled, so there is a high possibility that the food is brought into the supercooled state. That is, the food can be preserved with high quality without restarting the special temperature control from the beginning, and the maintenance time of the first set temperature that restarts the special temperature control from the beginning can be suppressed. As a result, the time during which the temperature in the refrigerator in the switching chamber 200 becomes higher than the usual set temperature can be shortened. Thereby, the precision of the high-quality storage of the food in the supercooled state is not reduced, and the influence of the temperature rise in the refrigerator in the switching chamber 200 on the high-quality storage of the existing food can be suppressed.

以上，在本實施形態2的冰箱1，控制裝置50係在是在特殊溫度控制中偵測到切換室門12之開閉的情況，並將切換室200之冰箱內溫度維持於第一設定溫度的情況，係使特殊溫度控制不從最初重新開始而仍然繼續。As described above, in the refrigerator 1 of the second embodiment, the control device 50 detects the opening and closing of the switch compartment door 12 during the special temperature control, and maintains the temperature in the refrigerator in the switch compartment 200 at the first set temperature. In this case, the special temperature control does not restart from the beginning but continues.

若依據本實施形態2的冰箱1，在是在特殊溫度控制中偵測到切換室門12之開閉的情況，並將切換室200之冰箱內溫度維持於第一設定溫度的情況，係使特殊溫度控制不從最初重新開始而仍然繼續。因此，不使特殊溫度控制從最初重新開始亦可高品質地保存食品，而可抑制使特殊溫度控制從最初重新開始之第一設定溫度的維持時間。結果，可縮短切換室200之冰箱內溫度成為比平常設定溫度更高之狀態的時間。藉此，不會降低將食品導入過冷卻狀態之食品之高品質保存的精度，且可抑制切換室200之冰箱內溫度的上升所造成之對既有食品之高品質保存的影響。實施形態3If the refrigerator 1 according to the second embodiment detects the opening and closing of the switching chamber door 12 during the special temperature control, and the temperature in the refrigerator in the switching chamber 200 is maintained at the first set temperature, the special The temperature control does not restart from the beginning but continues. Therefore, the food can be preserved with high quality without restarting the special temperature control from the beginning, and the maintenance time of the first set temperature for restarting the special temperature control from the beginning can be suppressed. As a result, the time during which the temperature in the refrigerator in the switching chamber 200 becomes higher than the usual set temperature can be shortened. Thereby, the precision of the high-quality storage of the food in the supercooled state is not reduced, and the influence of the temperature rise in the refrigerator in the switching chamber 200 on the high-quality storage of the existing food can be suppressed. Embodiment 3

以下，說明本發明之實施形態3，但是關於與實施形態1及2重複者係省略說明，並對與實施形態1及2相同的部分或相當的部分係附加相同的符號。此外，在本實施形態3，係在根據過去之切換室門12的開閉記錄進行特殊溫度控制上與實施形態1及2相異。Hereinafter, the third embodiment of the present invention will be described, but the description of those overlapping with the first and second embodiments will be omitted, and the same or equivalent parts as in the first and second embodiments will be given the same reference numerals. In addition, the third embodiment is different from the first and second embodiments in that special temperature control is performed based on the opening and closing records of the switching chamber door 12 in the past.

圖6係表示本發明之實施形態3的冰箱1之進行切換室門12的開閉時之切換室200的冰箱內溫度之時間變遷的圖。Fig. 6 is a diagram showing the temporal transition of the temperature in the refrigerator in the switching chamber 200 when the switching chamber door 12 is opened and closed in the refrigerator 1 according to the third embodiment of the present invention.

在本實施形態3，係每隔一小時將門開閉偵測部19所偵測之切換室門12的開閉次數記憶於記憶裝置51，並記憶數日份量。In the third embodiment, the number of opening and closing of the switching room door 12 detected by the door opening and closing detection unit 19 is memorized in the memory device 51 every hour, and the number of days is stored.

控制裝置50係從記憶裝置51所記憶之資訊，算出在各時間帶之切換室門12之開閉次數的平均次數。而且，將在各時間帶的平均次數中成為預設之第一臨限值(例如0.3次)以下的時間帶，即切換室門12之開閉次數少的時間帶設定成不使用時間帶。此處，切換室門12之開閉次數少的時間帶係因為使用者因睡眠及外出等而在住屋內未活動的可能性高，所以在不使用時間帶有切換室門12之開閉的情況，係作成不進行特殊溫度控制。藉由依此方式，考慮使用者之至目前為止之冰箱1的使用狀況，在食品投入之可能性低的情況，係藉由不進行發生冰箱內之溫度變動的特殊溫度控制，可高精度地確認食品投入。因此，可抑制冰箱內之溫度變動所造成之對既有食品之保存品質的影響。The control device 50 calculates the average number of opening and closing times of the switching room door 12 in each time zone from the information stored in the memory device 51. In addition, the time zone in which the average number of times in each time zone is equal to or less than the preset first threshold (for example, 0.3 times), that is, the time zone in which the number of opening and closing of the switching chamber door 12 is small, is set as the non-use time zone. Here, the time zone in which the number of opening and closing of the switching room door 12 is small is because the user is likely to be inactive in the house due to sleep, going out, etc., so the opening and closing of the room door 12 may be switched during non-use time. The system is made without special temperature control. In this way, considering the user’s current use of the refrigerator 1, when the possibility of food input is low, special temperature control that does not cause temperature fluctuations in the refrigerator can be used to confirm with high accuracy. Food input. Therefore, the influence of temperature fluctuations in the refrigerator on the preservation quality of existing foods can be suppressed.

此外，亦可在記憶裝置51，不僅記憶切換室200之結果，而且記憶其他的各貯藏室之門開閉偵測部19的開閉次數，並根據記憶裝置51所記憶之關於各貯藏室之門開閉的資訊，設定不使用時間帶。In addition, in the memory device 51, not only the result of the switching room 200, but also the opening and closing times of the door opening/closing detection portion 19 of other storage rooms can be memorized, and the door opening and closing of each storage room according to the memory device 51 Information, set the time zone not to be used.

又，從記憶裝置51所記憶之資訊，算出在各時間帶之切換室門12之開閉次數的平均次數。而且，將在各時間帶的平均次數中成為預設之第二臨限值(例如1.0次)以上的時間帶，即切換室門12之開閉次數特別多的時間帶設定成複數個生活時間帶。而且，在偵測到切換室門12之開閉的情況，作成在各生活時間帶僅在第一次之偵測到時進行特殊溫度控制，而在第二次以後之偵測到時係不進行特殊溫度控制。此處，因為切換室門12之開閉次數多的時間帶是使用者烹調中或購物後的可能性高，所以在生活時間帶之切換室門12的開閉係食品被投入的可能性高。因此，在切換室門12之第一次的開閉時係進行特殊溫度控制，且在烹調中或購物後的可能性低之第二次以後之切換室門12的開閉時，係因為食品被投入的可能性低，所以作成不進行特殊溫度控制。Furthermore, from the information stored in the memory device 51, the average number of opening and closing times of the switching room door 12 in each time zone is calculated. In addition, the time zone in which the average number of times in each time zone is equal to or greater than the preset second threshold value (for example, 1.0 times), that is, the time zone in which the number of opening and closing of the switching room door 12 is particularly large, is set as a plurality of life time zones . In addition, when the opening and closing of the switching chamber door 12 is detected, special temperature control is performed only when the first detection is performed in each life time zone, and it is not performed when the second and subsequent detections are performed. Special temperature control. Here, since the time zone where the number of times of opening and closing of the switching chamber door 12 is high is that the user is more likely to be cooking or after shopping, the opening and closing of the switching chamber door 12 in the life time zone is highly likely to be injected. Therefore, when the door 12 is switched for the first time, special temperature control is performed, and the possibility of switching the door 12 after the second time during cooking or shopping is because food is put in. The possibility of this is low, so no special temperature control is required.

依此方式，考慮使用者之至目前為止之冰箱1的使用狀況，作成在食品投入之可能性高的情況係進行特殊溫度控制，且在食品投入之可能性低的情況係不進行特殊溫度控制。藉由依此方式，可將食品高精度地導入過冷卻狀態，且可抑制冰箱內之溫度變動所造成之對既有食品之保存品質的影響。In this way, considering the user’s use of the refrigerator 1 so far, special temperature control is performed when the possibility of food input is high, and special temperature control is not performed when the possibility of food input is low. . In this way, the food can be introduced into the supercooled state with high precision, and the influence on the preservation quality of the existing food caused by the temperature fluctuation in the refrigerator can be suppressed.

以上，在本實施形態3之冰箱1，控制裝置50係從記憶裝置51所記憶之資訊，將在一天之中在各時間帶之切換室門12之開閉次數的平均次數為第一臨限值以下的時間帶設定成不使用時間帶。而且，在不使用時間帶偵測到切換室門12之開閉的情況，係不進行特殊溫度控制。As described above, in the refrigerator 1 of the third embodiment, the control device 50 is the information memorized from the memory device 51, and sets the average number of opening and closing times of the switching door 12 at each time zone in a day as the first threshold The following time zones are set as non-use time zones. Moreover, when the opening and closing of the switching chamber door 12 is detected during the non-use time zone, no special temperature control is performed.

又，若依據本實施形態3之冰箱1，考慮使用者之至目前為止之冰箱1的使用狀況，作成在食品投入之可能性低的情況係不進行發生冰箱內之溫度變動的特殊溫度控制。藉由依此方式，可高精度地確認食品投入，而可抑制冰箱內之溫度變動所造成之對既有食品之保存品質的影響。In addition, according to the refrigerator 1 of the third embodiment, considering the user's use condition of the refrigerator 1 so far, it is made that special temperature control that causes temperature fluctuations in the refrigerator is not performed when the possibility of food input is low. In this way, the input of food can be confirmed with high accuracy, and the influence of temperature fluctuation in the refrigerator on the preservation quality of existing food can be suppressed.

又，在本實施形態3之冰箱1，控制裝置50係從記憶裝置51所記憶之資訊，將在一天之中在各時間帶之切換室門12之開閉次數的平均次數為第二臨限值以上的時間帶設定成生活時間帶。而且，在生活時間帶偵測到切換室門12之開閉複數次的情況，係僅在第一次之偵測到時進行特殊溫度控制，而在第二次以後之偵測到時係不進行特殊溫度控制。In addition, in the refrigerator 1 of the third embodiment, the control device 50 is the information memorized from the memory device 51, and sets the average number of opening and closing times of the switching room door 12 at each time zone in a day as the second threshold The above time zone is set as the life time zone. Moreover, in the case of detecting the opening and closing of the switching room door 12 multiple times during the life time zone, the special temperature control is only performed when the first detection is performed, but not when the second detection is performed. Special temperature control.

又。在本實施形態3之冰箱1，控制裝置50係設定複數個生活時間帶。而且，在同一生活時間帶偵測到門之開閉複數次的情況，係僅在第一次之偵測到時進行特殊溫度控制，而在第二次以後之偵測到時係不進行特殊溫度控制。also. In the refrigerator 1 of the third embodiment, the control device 50 sets a plurality of life time zones. Moreover, when the door is opened and closed multiple times during the same life time, the special temperature control is only performed when the first detection is performed, and the special temperature is not performed when the second detection is performed. control.
