571066 ⑴ 玫、發明說明 (發明說明應敘明：發明所屬之技術領域、先前技術、内容、實施方式及圖式簡單說明) 【發明之技術領域】 本發明係關於冰箱之冷卻儲藏室，尤其是關於製冰室之 結構及控制方法以及弱冷凍室之控制方法。 【先前技術】 近年來冰箱係跟著生活多樣化而收容量也有趨於大型 化之傾向，其形態大都因門扇之開閉次數多，使用頻度高 之故而在冰箱本體上部配設儲藏物收容容積大的冷藏 室，並在其下部配置蔬菜室及冷凍室，同時在蔬菜室與冷 凍室間獨立設置具有製冰裝置之製冰室與可使室内切換 成自冷凍溫度至蔬菜保存溫度的複數種溫度區域之溫度 切換室者。 如此由於設有儲藏溫度互異的多數之儲藏室，在冷卻器 方面也由先前之單一方式改變為採用各溫度區域專用之 冷卻器，例如使冷凍溫度用冷卻器與冷藏溫度用冷卻器等 兩種冷卻器對應於各自之溫度室而設置之結構。 並且，在具有如上述複數個冷卻器之冷卻方式，基於對 於儲藏室的冷卻效率上，則將對應於各自儲藏溫度的冷卻 器配置於該儲藏室背面等附近。就是說一向是使冷藏用冷 卻器配置於冷藏室附近，且連較該冷藏室溫度稍呈高溫的 蔬菜室也使之鄰近於冷藏室而配設，冷凍用冷卻器則使之 設在冷凍室背面部，同樣地也使會呈冷凍室溫度的製冰室 或溫度切換室配置於冷凍室附近（將此種情形態稱為第一 形態）。 571066 ⑺ 按在冷凍食品時，若儘使食品快速通過自· 1 °C至-5 °C之 食品最大冰晶生成區域，便可在不致使食品細胞組織受到 破壞而失去鮮度下加以冷凍保存。 因此以家庭用冷藏庫冷凍食品時，一般採取藉由提高冷 凍循環的壓縮機之旋轉數等而提高冷凍能力，藉以提高食 品冷卻速率而快速冷凍之方法。然當食品溫度處於適合於 保存的溫度，例如處於-18 °c以下時，卻有因凍結程度過 度而不能用菜刀切開肉或生魚片之問題存在。 與此相對，最近知曉有一種當提高食品之冷柬溫度，在 -7 °C至-1〇 °C (下稱為弱冷凍溫度區域）下進行冷凍保存 時，對於長期保存雖有困難，但對於數週間左右之保存卻 不致有任何問題且在烹調時馬上可用菜刀切開之方法，因 此曾揭露有一種具有可切換成包括弱冷凍溫度區域在内 的各種溫度設定之切換室的冰箱。 該切換室係在室内溫度相對於目標設定溫度為高時則 打開設在箱内後方之擋板而引進冷空氣，室溫低時則執行 以加熱器加熱而保持於設定溫度之控制（將此種形態稱為 第二形態）。 【發明所欲解決之課題】 然在第一形態之冰箱，其製冰室必被配置於蔬菜室下 部，且就冰箱之整體佈置而言，也偏位於下方位置，因而 欲取出冰時則須向前彎著身子，致在夏天等須頻繁取用冰 塊時，會造成使用上極其不便之困擾。 冷藏室之外形尺寸，因受到國内的廚房需求情況等設置 571066 (3) 條件上限制，致進深尺寸、高度尺寸均已達到其極限，要 擴大儲藏空間也因此而受到限制，使得使用者提高使用方 便性之要求與日倶增。 至於第二形態之冰箱，若在設定為弱冷凍溫度區域的切 換室内擺放未經凍結的常溫狀態之食品時、由於其室内溫 度比例如-25°C之冷凍室溫度為高，致食品溫度要通過最 大冰晶生成區域的溫度區域必需化一段長時間，即必定會 變成所謂的緩冷凍模式。 按食品受到上述缓冷凍模式時，必會造成食品細胞組織 被破壞，肉等會發黑，且因蛋白質之自我分解或因脂肪分 之氧化而會引起食品變壞之問題。 加上當擺放溫度比弱冷凍溫度區域為高的新食品時，連 已保存於弱冷凍溫度區域的既有冷康食品之溫度也會隨 著室内溫度升高而上升，因而有食品之味道或鮮度會變壞 之問題存在。 本發明之目的即在於解決上述問題而對於第一形態之 冰箱提供一種為了對應於多樣化的使用者需求而提供一 種藉由對於儲藏室之有效的冷氣通道機構或冷卻機器之 配置結構，使製冰室配置於冷藏室空間之一隅而使用方便 的儲藏室佈置者。 對於第二形態之冰箱則提供一種在弱冷凍溫度區域進 行食品保存時，可在不致使食品之鮮度或味道受損下加以 保存之冰箱者。 【課題之解決手段】 571066 (4) 發瞵讓_讀買 申請專利範圍第1項之發明，係一種冰箱，其特徵為包 括有：由配置在冰箱本體上部之冷藏用冷卻器及冷藏用風 扇所冷卻的冷藏室；由配置在冰箱本體下部的冷凍用冷卻 器及冷凍用風扇所冷卻的冷凍室（9);設在上述冷藏室與 冷凍室之間的蔬菜室；具有以絕熱區劃而配置在上述冷藏 室之底部一隅的自動製冰裝置之製冰室；以及設在該製冰 室的背部之製冰用風扇；且將由冷凍用冷卻器生成之冷空 氣經由通道及製冰用風扇而送風至製冰室，並在蔬菜室背 面並排設置含有冷凍用風扇的上述通道及來自於製冰室 的回流通道。 藉此結構，即可使製冰室之高度位置變高，使得欲取用 冰塊時，無須使姿勢向前彎著身子即可輕鬆地取出冰塊， 同時即使由位於冰箱本體下部的冷凍用冷卻器，延伸而設 置用以向上方的製冰室部導入冷空氣之通道，但只要藉由 使冷凍用冷卻器與冷卻風扇，及冷空氣通道或回流通道並 排設置在儲藏室背面，即可在不致於損及箱内容積效率下 可更進一步使各儲藏室背面形狀加以平坦化而實現收容 空間之有效活用。 申請專利範圍第2項之發明，其特徵為在冷凍用冷卻器 生成之冷空氣係直接以製冰室用風扇經由冷空氣通道而 送風於製冰室，申請專利範圍第3項之發明，其特徵為將 經在冷康用冷卻器生成而送風於冷；東室之冷芝氣，以製冰 室用風扇經由冷空氣通道而送風於製冰室。 藉此結構，即可確實地將低溫之冷空氣送風至與冷凍用 -10 -

571066 ⑻ 冰箱本體最上部之冷凍室者，其係藉由以未圖示之鉸鏈裝 置轉動自如地樞支在本體一側的門扇閉塞其前面開口部。 在冷藏室（5)之下部，介以隔板（6)形成有蔬菜室（7)，其 係用以收容保存在比冷藏室溫度稍高的溫度之蔬菜等。 在蔬菜室（7)之下方介以絕熱隔離室（9)配置有供收容冷 凍食品之冷凍室（9)。該冷凍室（9)係劃分成上下兩格，並 在上格設有快速冷凍部（1 〇)。 上述蔬菜室（7)或冷凍室（9)之結構，在圖式上雖看不 出，但其係設成為：以門扇閉塞其前面開口部，且在門扇 内侧安裝有向儲藏室内方向延仲之框體，俾供在該框體上 面載置收容容器，並藉由與安裝在上述框體後端之未圖示 的滾輪與設在箱内侧壁之軌道構件等之扣合滑動，使收容 容器可向前後方向自由抽出者。 並且在冷藏室（5)空間之下方一隅，形成有以絕熱壁（11) 劃分之製冰室（12)。該製冰室（12)係用以接收來自於設其 上部之冷藏室（5)内的給水槽（13)之供水而使之裝上於自 動製冰裝置（1 4)，同時將用以接收經製得之冰塊而儲存之 儲冰箱配設成可自由抽出，且可接收來自於後述冷凍用冷 卻器（2 7)之冷空氣而冷卻成冷凍溫度者。 自動製冰裝置（14)係在裝在製冰盤底部外面之製冰檢 測感測器（5 5 )檢測到-19 °C時，則視為所有製冰盤内之水已 結成冰而完成製冰，然後執行使製冰盤之冰塊落下於儲冰 容器之脫冰動作。脫冰係採取使製冰盤反轉且使其轉動至 1 8 0度時限制其一侧端之轉動而維續對該製冰盤施加扭 -14 -

[Previous technology] In recent years, refrigerators have tended to increase in capacity with the diversification of life. Most of their forms are equipped with large storage capacity on the upper part of the refrigerator due to the large number of door opening and closing times and high frequency of use. The refrigerator compartment is provided with a vegetable compartment and a freezer compartment at the lower part, and an ice-making compartment with an ice-making device and a plurality of temperature areas that can switch the room from the freezing temperature to the vegetable storage temperature are independently set between the vegetable compartment and the freezing compartment. Temperature switch room. In this way, because there are many storage rooms with different storage temperatures, the cooler has also been changed from the previous single method to a dedicated cooler for each temperature area, such as a cooler for freezing temperature and a cooler for refrigerating temperature. This type of cooler has a structure corresponding to each temperature chamber. In addition, in the cooling method having the plurality of coolers as described above, based on the cooling efficiency with respect to the storage room, the coolers corresponding to the respective storage temperatures are arranged near the back of the storage room and the like. That is to say, the cooler for refrigerating is always arranged near the refrigerating compartment, and even the vegetable compartment that is slightly higher than the temperature of the refrigerating compartment is also arranged adjacent to the refrigerating compartment. The refrigerating cooler is placed in the freezing compartment. Similarly, an ice-making chamber or a temperature-switching chamber, which has a temperature of the freezing chamber, is arranged in the vicinity of the freezing chamber (this aspect is referred to as a first aspect). 571066 ⑺ When pressing on frozen food, if the food is allowed to quickly pass through the maximum ice crystal generation area of the food from 1 ° C to -5 ° C, it can be frozen and stored without damaging the food cell tissue and losing its freshness. Therefore, when freezing food in a domestic refrigerator, generally, a method of increasing the number of rotations of a compressor in a refrigeration cycle to increase the freezing capacity, thereby rapidly freezing the food by increasing the cooling rate of the food. However, when the temperature of the food is suitable for storage, for example, below -18 ° c, there is a problem that the meat or sashimi cannot be cut with a kitchen knife due to excessive freezing. In contrast, recently, it has been known that when the cold storage temperature of food is increased and stored at -7 ° C to -10 ° C (hereinafter referred to as the weak freezing temperature region), it is difficult to store it for a long time, but The method of storing for several weeks without any problems and immediately cutting it with a kitchen knife during cooking has been disclosed. Therefore, a refrigerator having a switching room that can be switched to various temperature settings including a weak freezing temperature region has been disclosed. This switching room is to open the baffle provided in the rear of the box to introduce cold air when the indoor temperature is high relative to the target set temperature. When the room temperature is low, the heater is controlled by the heater to maintain the set temperature. This form is called the second form). [Problems to be Solved by the Invention] However, in the refrigerator of the first form, the ice-making chamber must be arranged at the lower part of the vegetable compartment, and the overall layout of the refrigerator is also located at a lower position, so when you want to take out the ice, you must Bending forward, causing extreme inconvenience when using ice cubes frequently in summer, etc. The external dimensions of the refrigerating compartment are limited by the conditions of domestic kitchen requirements such as setting 571066 (3). The depth and height dimensions have reached their limits. Expansion of the storage space is also constrained. The requirements for ease of use increase with each passing day. As for the refrigerator of the second form, if the unfrozen normal temperature food is placed in the switching room set to the weak freezing temperature region, the food temperature will be higher because the indoor temperature is higher than the freezing room temperature of, for example, -25 ° C. It is necessary to pass through the temperature region of the maximum ice crystal generation region for a long time, that is, it must be changed into a so-called slow freezing mode. When the food is subjected to the above-mentioned slow freezing mode, the food cell tissue will be destroyed, the meat will be darkened, and the food will be deteriorated due to the self-decomposition of protein or the oxidation of fat. In addition, when new food is placed at a higher temperature than the weak freezing temperature zone, the temperature of even the cold food that has been stored in the weak freezing temperature zone will rise with the indoor temperature, so there is a taste of the food or There is a problem that the freshness deteriorates. An object of the present invention is to solve the above-mentioned problems and provide a refrigerator of the first form with a configuration of an air-cooling channel mechanism or a cooling machine that is effective for a storage room in order to respond to a variety of user needs, and make The ice compartment is located in one of the refrigerating compartment spaces and is a convenient storage room decorator. The refrigerator of the second aspect provides a refrigerator that can be stored without impairing the freshness or taste of the food when the food is stored in a weak freezing temperature region.

Or compressor (41). The front of the refrigerating fan (22) is provided with a cold air exhaust port (23) for the upper part of the refrigerating compartment, and at the same time, at the back of the refrigerating compartment, a channel (24) is formed from the upper part of the inner part on both sides up and down, (24) is provided with a cold air outlet (25) at a specific interval position toward the inside of the box, and the cold air is blown out according to the intervals of the storage shelf (17) in the refrigerator (5), thereby cooling and refrigerating indoor. According to the above structure, since the cooler for refrigerating is arranged on the back of the refrigerating compartment with a large area, the capacity of the cooler can be enlarged to increase the cooling force, and even if the evaporation temperature is increased, a sufficient cooling chamber can be obtained indoors, thereby reducing the The contained food takes away moisture to prevent the food from drying out, and because the two sides are used as a passage, the indoor and outdoor can be flattened to effectively use the installation and storage space. A cold air inlet (2 6) is arranged on the lower back of the refrigerating compartment (5), and the cold air circulated through the refrigerating compartment is sucked back and returned to the cooler (21). A freezer cooler (2 7) is arranged on the back of the freezer compartment (9) below the refrigerator body. A refrigerating fan (28) is provided above the refrigerating cooler (27), which can blow cold air out of the cold room; it is constructed in the east room, so that part of the cold air can be extended -16-571066 (11). The passage (30) is guided to the ice-making fan (3 1), and then blows out of the ice-making chamber (12). Between the ice-making fan (3 1) and the temperature switching chamber (15), as shown in the enlarged cross-sectional view of the ice-making chamber section of FIG. 3, a switching chamber passage (3 2) and a cold air baffle are provided. (16) so that part of the cold air from the ice-making fan (31) is attracted to the switching chamber passage (32) and blown out of the temperature switching chamber (15) through the cold air baffle (16). The cold air baffle plate (16) for the temperature switching chamber is buried in the isolation portion between the ice making chamber (12) and the temperature switching chamber (15), so that the storage space is not reduced. And because the passage (30) to the ice-making chamber (12) can be used, there is no need to set a dedicated passage space for the temperature switching chamber (15), and the effective use of the storage space can be achieved. A cold air inlet (34) (3 5) is formed in the ice-making chamber (12) and the temperature switching chamber (15), and an ice-making chamber is provided from the back of the vegetable chamber (7) to the freezing chamber (9). The return channel (3 6) and the switching chamber return channel (37) are used to return the circulating cold air to the refrigerating cooler (27). These cold air circulation channels are shown in Fig. 4 in the longitudinal sectional view and Fig. 5 in the AA sectional view in Fig. 2 or in Fig. 6 along the BB sectional view. (30) with the return channel (3 6) (3 7) from the ice-making room and the switching room, or the refrigerating cooler (2 7) and the refrigerating fan (2 8) and the above return channel (3 6) ( 3 7), are arranged side by side on the back of the freezer compartment (9) or vegetable compartment (7). With this structure, the unevenness on the back of the storage room can be minimized, and the protruding parts in each room can be reduced, and the vegetable room (7) or cold beam -17- 571066 can be effectively used _ 囔 页 囔 室 (9 ) Volume, which makes the indoor space easy to plan and use. At the same time, by parallel arrangement as described above, each channel can be made into a simple structure, so that efficient cold air supply can be achieved without loss of ventilation resistance caused by channel bending. . Furthermore, on the back of the refrigerator body (1) from the vegetable room (7) to the temperature switching room (15), there is a cold; an east cooler (27) or cold; an east fan (28) or each channel ( 30) (36) A recessed portion (39) is provided in parallel, and a control circuit board (40) for performing operation control of the refrigerator is arranged in the recessed portion. Next, the operation mode of the refrigerator will be described as follows. Fig. 8 is a schematic diagram showing a refrigeration cycle of the present invention. The refrigerant discharged from the compressor (41) in the mechanical room located at the lower rear of the freezing chamber (9) is radiated by the condenser (43), and is controlled by the flow path at the switching valve (42) to cool the refrigerator. The refrigerator (21) or the refrigerating cooler (27) is cooled, and the refrigerating cooling mode and the refrigerating cooling mode are alternately performed as described below. The refrigerating cooling mode is implemented when the temperature of the refrigerated space is higher than the set temperature. In this mode, the switching valve (42) is switched to allow the refrigerant to flow through the capillary tube (44), and the refrigerant is cooled in the refrigerating cooler (21) by evaporating. At this time, the refrigerating fan (22) is driven in synchronization with the switching of the refrigerant flow path, so that cold air is blown out of the refrigerating space for cooling. The refrigerant gasified by heat exchange with the cooler is returned to the compressor (41). Freeze cooling mode starts when the temperature of the freezing space is higher than the set temperature. In this mode, the switching valve (42) is switched to allow the refrigerant to flow through the capillary tube (48). After the refrigerating cooler (2 7) evaporates, the storage pressure is (45) through (13) (13) 571066. ) And check valve (4 6) and return to the compressor (41). In addition, the cooling fan (2 8) is synchronized with the switching of the refrigerant flow path to the cooling cooler (2 7) and operates at a normal rotation number to cool the freezing space. The phase-removal mode is to apply power to a defrosting heater (4 7), such as a glass tube heater, arranged at the lower part of the freezing cooler (2 7) to perform cypress removal of the freezing cooler (). The defrosting mode is implemented, for example, in a time sequence in which the accumulated time of operation of the compressor (41) has passed for eight hours, and is started when switching to the refrigerating and cooling mode. And through the defrost sensor (5 6) installed in the refrigerating cooler (2 7) & then the defrost ends when the refrigerating cooler (2 7) has been heated to a specific temperature, such as 3 C. Mode and return to cooling operation. The quick ice making mode starts with & operation of the operation panel (54) provided on the surface of the refrigerator door, and the cold air baffle (1 6) is fully opened, and the rotation of the ice making fan (3 1) is set to Rotate at a high speed so that the amount of cold air sent to the ice making chamber & add 'is continued until the ice making is completed or the rapid ice making mode is cancelled. The downward pumping mode is to switch the refrigerating cooling mode and the freezing cooling mode to 'close the switching valve (42) and rotate the compressor (4 丨) at a specific time, for example, 30 seconds, so as to recover the residual cooling in the cooling for freezing. The refrigerant of the device (27). Next, a cooling (cooling) mechanism of each storage room will be described. The above-mentioned coolers (2 1) (27) are used to cool I and 2 gases, which are blown out of the respective leaning room spaces by the respective cooling fans (22) (28) on the upper part for refrigeration and freezing. Or, the cold air blown out will repeat the order of the cooling of each storage room, as shown by the arrow mark, and the cycle from the suction port to the cooler. -19- 571066 Send _ Continue to buy (14) ring to Each storage room is cooled and maintained at a specific set temperature. In the refrigerating compartment (5), the cold air from the refrigerating cooler (21) is blown by a refrigerating fan (2 2) above the refrigerating compartment, and the remaining part is diverted to the back of the refrigerating compartment. The channels (24) on both sides are blown out of the refrigerating room by the cold air blowing outlets (2 5) passing through the channels (24) at a certain interval and upward and downward, and the cold air circulating in the refrigerating room will be repeated. Refrigeration cycle from the suction port (26) to the cooler (21). When the refrigerating compartment is cooled to a certain temperature, the refrigerating fan (2 2) is stopped. On the other hand, when the indoor temperature rises above a certain temperature due to the stopping of the cooling operation, the fan (22) is driven again to implement a refrigeration cycle. The role of refrigeration. The cooling control of the freezing space is basically the same as that of the above-mentioned refrigerating compartment, but the cold air of the freezing cooler (2 7) is discharged to the freezing compartment (9) through the freezing fan (2 8), and is The air duct (30) provided in the upper direction of the back of the vegetable compartment (7) in the upper part of the freezing compartment is guided to the ice-making compartment (1 2) in one of the upper refrigerating compartment spaces. Then, by rotating the ice-making fan (3 1) which is a third fan on the back of the ice-making chamber, part of the cold air from the freezing fan (2 8) is blown out of the ice-making chamber (12). At the same time, part of it is introduced into the adjacent temperature switching chamber (15) through the switching chamber passage (32) and the cold air baffle (16) to cool it. The cold air baffle (16) changes the opening area of the cold air outlet according to the set temperature, so as to control the amount of cold air inflow, so that the temperature switching chamber (15) can be maintained at the freezing temperature or chilling temperature. Waiting for a specific temperature of -20-571066, the Bun said that it would depend on buying another (15) degree zone. The cold air cooled by the ice-making chamber (12) and the temperature-switching chamber (15) will return the ice-making chamber return channels (36) on both sides of the air-supply channel (30) formed on the back of the vegetable room (7). And switch the chamber return channel (37) to return to cold; the eastern cooler (27) merges with the cold air circulating through the freezing chamber (9) and continues to receive the cooling cycle of cooling again. Furthermore, the storage room provided at the side of the ice-making room (12) is not limited to the temperature switching room as in the above embodiment, but it can also be a special room or a fast-freezing room that has a lower temperature than the refrigerating room. The cooling chamber can also be used as a cooling chamber, which can be freely set and effectively used. Next, a modification of the present invention will be described as follows. < Modification 1 > Fig. 9 is a schematic diagram showing a channel structure explained in the above embodiment, and Fig. 10 is a schematic diagram showing a channel structure according to Modification 1. Figs. Regarding one embodiment of the present invention, as shown in FIG. 9, the cold air generated by the cooling cooler (2 7) is taken, and the cooling fan (2 8) is sent to the cold air passage (30). The ice-making fan (3 1) is blown out of the ice-making chamber (1 2) from the top, but the modification 1 is shown in FIG. 10, which uses the cooling generated by the cooling cooler (27). The air is blown out of the freezing chamber (9) by a refrigerating fan (28), and the cold air in the freezer compartment space is blown out of the ice making chamber by an ice making fan (31) through a passage provided behind the freezing chamber ( 12) Composition. Alternatively, as shown in FIG. 11, the cold air generated through the cooling cooler (2 7) may also be taken out of the ice making chamber by an ice making fan (3 1) directly through the passage-21-571066 (16) Γ # 5ίίίϊ · .-- * * (12) Foot composition. In this case, the refrigerating fan (28) can be arranged below the cold rolling cooler (2 7), so that the structure can not only improve the refrigerating capacity of the freezing compartment (9), but also reliably make the The ice chamber is cooling. < Modification 2 > When the automatic ice-making device performs an ice-making operation, except for the defrost mode, the air-ice fan (31) is operated. ^ During the defrost operation of the male prisoner, the freezing cooler (2 7) will become relatively high. If the air in the warm atmosphere is sent to the ice making chamber (12), not only 1: the internal temperature will be significant Land rise and prolong ice-making time will also cause storage < Existing ice melts. On the other hand, in the refrigerating cooling mode, although the freezing cooler (a?) Does not cool down, the temperature of the cooler is still kept at a low temperature. Therefore, the ice making chamber (12) can be operated by operating the ice making fan (3 丨). ) Continue to be cooled. Therefore, in addition to the defrosting mode, the ice-making fan (31) is operated even if it is not in the freeze-cooling mode, so that the ice-making time can be shortened, and the temperature in the cabinet can be reliably maintained. < Modification 3 > In the refrigerating and cooling mode, the ice-making fan (31) is operated at a low speed, and in the east cooling mode, 'the ice-making fan (31) is operated at a high speed and a cooler is added. (2 7) It is less affected by cold running or low speed running. Therefore, in the refrigerating and cooling mode, power can be saved, and in the refrigerating and cooling mode, even if the ice making fan (3 1) is made at high speed, the result is still in the gap ratio mode compared with the normal high-speed operation. The ice-making fan (31) is used to cool the ice-making chamber (12) at low speed. -22- 571066 Praise _Read Buy ⑼ < Modification 4> When the user sets the quick ice-making mode on the operation panel (54), the user can enter any specific time, such as the 8-hour quick cooling mode. And until it is detected that the water supply tank (1 3) is short of water or the ice storage capacity is full, the ice making fan (3 1) will be continuously operated at high speed. As a result, ice can be made quickly and efficiently. < Modification 5 > In this modification, when the user sets the quick ice making mode on the operation panel (54), the setting temperature of the freezing compartment (9) is reduced. For example, if the setting temperature is -20 ° C, Reduce for example 3 K. The ice-making fan (3 1) is operated in synchronization with the compressor (41). When the set temperature of the freezing chamber (9) is lowered, the actual indoor temperature becomes higher than the set temperature. Therefore, the compressor (4 1) The number of rotations must be increased in order to increase the freezing capacity. Therefore, the number of rotations of the ice-making fan (31), which runs synchronously with the compressor (41), will also automatically increase to increase the cold-resistance capability, so that rapid ice-making can be achieved. < Modification 6 > In this modification, the number of rotations of the ice-making fan (31) is adjusted to maintain the indoor temperature of the ice-making chamber (12) while the ice-making operation is stopped. That is, as long as the ice making operation is stopped, it can be maintained without dissolving the ice cubes. Therefore, it is possible to efficiently perform ice making by reducing the number of rotations of the ice making fan (3 1). The cooling of the chamber (12) keeps the ice cubes well and the operation of the ice-making fan (31) tends to be efficient and save power. At this time, if the temperature in the ice making chamber is low, the ice making fan (3 1) can also be stopped. -23-571066 (18) Hair Bunting _ Continued < Modification 7 > In this modification, the ice-making fan (31) is operated in the downward pumping mode. The push-to-pump operation is implemented only when the cooling mode is switched. Therefore, it is advisable to recover the refrigerant from the refrigerating cooler (27) to the compressor (41) as quickly as possible. Running the ice making fan can increase the amount of heat exchange between the air in the freezing space and the cooling cooler, so the refrigerant recovery can be completed quickly.

When the rapid freezing operation is in operation, the timing of the start of the defrost is not activated, and the operation is waited until the end of the rapid freezing. The temperature is at the lower part of the back wall of the refrigerator (1 0 1). In the machinery room (1 1 4), there is a compressor (1 1 5), and a cold demon device or a variety of replies with the compressor to form a refrigeration cycle. A fan (hereinafter referred to as a C fan) (1 2 5) is provided near the condenser (1 2 1). Figure 14 shows the refrigeration cycle of the refrigerator (101). The refrigerant discharged from the compressor (1 1 5) passes through the condenser (121) and is switched by a three-way valve (122). One outlet of one of the three-way valves (122) is connected with a refrigerated capillary (1 2 3) and R steam (1 10) in sequence, and the other outlet is connected with a refrigerated capillary (124) and F steam ( 112) and pressure accumulator (116). Therefore, the three-way valve (122) can be -26-571066. See_buy (21) is switched and controlled to the state where the refrigerant is only transferred to the R steam (1 1 〇) side, and the state is only transferred to the F steam (112) side. FM steam (110) (112) both sides of the refrigerant in the fully open state, and the valve (1 2 2) to cut off the refrigerant flow in the four closed states of the four circulation states. The outlet pipe of the pressure accumulator (116) is connected with a check valve (1 1 7) in the machine room (114), and the outlet side of the check valve (1 1 7) is connected with r steam (ii 〇) The outlet pipes are merged and connected to the suction side of the compressor (1 1 5). Figure 15 is a block diagram of the control system of a 5 series refrigerator (101). As shown in the figure, in the upper part of the back of the refrigerator (101), a control part (164) composed of a microcomputer for controlling the refrigerator is connected with a compressor (115) for driving a refrigeration cycle; So that the cold air from the RF steam (110) (112) is exhausted to the R fan (111), F fan (113), C fan (125), I fan (13 1), S fan (142) in each storage room ) And baffle (137) for adjusting the amount of cold air; for detecting each room temperature and controlling and adjusting the scale sensor (丨 4 4), F sensor (145), S sensor of each cooling machine (141), and heater (143); a glass tube heater (i 4 6) and a D sensor (1 4 7) for controlling the defrost of the hair dryer, and a refrigerator (丨〇4) The door (1 18) is used to perform various operation control or display. The temperature control operation of the refrigerator (丨 〇 丨) in the normal state is described below. Compressed and pressurized high-temperature refrigerant is applied to the compressor (1 1 5). After the condenser (121) releases heat, it enters the three-way valve (122) and is steamed at R (110) or at F by switching the flow path. Steaming (112) evaporates and cools, so that alternate operation of the following refrigerating mode and freezing mode is performed alternately. The refrigerating mode is a control implemented to keep the temperature inside the refrigerated space (130) at a specific set temperature of -27-571066 (22) Fan_Ganbuy. It is switched when the temperature ratio of the refrigerated space rises. The three-way valve (122) allows the refrigerant to flow from the refrigerating capillaries to the R steam (110) side, and evaporates the cooling fan guide space (130) generated by the evaporation to cool the indoor person. The vaporized and cooled back to the compressor (115), but the flow path on the side of the F steam (112) is provided with (117). When the refrigeration mode is performed, the refrigerant will not flow from R to the lower evaporation temperature. The F was steamed (1 1 2) and coagulated again. In the R steam (110) cooling, the R fan (111) is switched with the refrigerant flow path to blow cold air out of the refrigerated space (130). Freezing mode is implemented when the temperature in the freezing space (1 40) is higher than the set temperature. The three-way valve (1 2 2) is used to switch the refrigerant flow path so that it can flow to the refrigerating capillary (124) to form F steam (112) for evaporation, pass the accumulator (116) and the check valve (117). ) And return to the compressor (115) cycle. In addition, in the F steam (1 1 2) cooling, the F fan (113) is driven by switching the refrigerant flow, and is operated at a normal rotation number to cool the inside of the tank. Then, according to the graph of FIG. 16 and the flow of FIG. 17 The picture is as follows for the preservation of the food with a weak cold capacity and a weak freezing temperature range (from -5 ° C to -10 ° C).
在步騾1 ( S 1 )，則指示將常溫食品收容於弱冷凍 之容器（1 3 9 )並關閉門扇，同時由使用者操控操作 而指示（S 2)該食品之保存溫度。該保存溫度應設定 以菜刀切開該食品的屬弱冷凍溫度區域之自-5 °CAt step 1 (S1), the normal temperature food is stored in a weakly frozen container (139) and the door is closed. At the same time, the user controls the operation to indicate (S2) the storage temperature of the food. The storage temperature should be set to -5 ° C, which is a weak freezing temperature region for cutting the food with a kitchen knife.

Freezing room storage situation (106) Department (118) In the easy to -10 ° C -28-571066 (23) 5 here is set to -8 C. In step 3, the user controls the weak freezing switch of the operation section (118) to be turned on. With this, the control unit (1 6 4) switches the cold rolling cycle to cold; in the east mode, the F fan (113) is rotated at a higher number of rotations than usual, and the S fan (142) is also rotated. Then, the baffle (137) is opened, and the cold air of F steam (11 2) is supplied to the weak freezing chamber (1 06), thereby, as shown in FIG. 16, the rapid freezing operation is started (S 4) , Until the food temperature in the weak freezing chamber will reach a set temperature lower than the lower limit of the maximum ice crystal generation region, in this case it is -10 ° C. In this case, the heater (1 4 3) is not energized. Once the rapid freezing operation is implemented, the food stored in the container (139) is about to be cooled and will quickly pass through the maximum ice crystal generation region from -1 ° C to -5 ° C, which is the temperature region where the moisture of the food is most likely to form solid ice. Therefore, the food can be frozen while the taste or freshness is still sealed inside. When the rapid freezing operation is continued and the temperature of the food detected by the S sensor (1 4 1) drops below -10 ° C, the rapid freezing mode is stopped. If it is above-l0t: above, continue to step 4 Quick freeze (S5). In step 6, the shutter (13 7) is closed, while the S fan (14 2) is stopped, and the heat heater (1 4 3) is heated. At this time, PID (Proportional-Integral-Derivative) control is applied in such a way that the over-adjustment does not exceed -5t. This PID constant is ideally set such that it does not overshoot the time required to reach the target temperature. When the food temperature rises to -8 ° C as shown in FIG. 5, the heater (143) is stopped (S7), and then the shutter (ID) is closed to maintain the control (S8) so that the temperature in the box becomes -8 ° C. -29-571066 (24) Therefore, by implementing a rapid freezing operation, the food is quickly passed through the maximum ice crystal generation area, and then stored in a weak freezing temperature area, so that the taste or freshness of the food is not deteriorated and it is easy to use. Keep frozen while cutting. At this time, the food that has been stored in the weak cold room may be cooled by a lower temperature than the weak freezing temperature area, but a temporary temperature drop like this will not affect the taste or freshness of the food, so Can be kept well. In addition, even if the weak freezing chamber (106) is provided in the freezing space (140), the temperature can be easily increased to the weak freezing temperature region by heating with a bottom heater (14 3). Since the rapid freezing operation is performed to a temperature lower than the maximum ice crystal generation region < the lower limit value is a specific temperature, even if the volume of food such as a meat block is large, it can be cooled to the maximum ice crystal generation region ^ ' Therefore, regardless of the volume of the food, the taste or freshness can be kept uniformly. In this case, the temperature of the food may be different from the temperature in the box due to rapid operation, but if the temperature in the box and the temperature of the food are different from the type or size of the food, then how much difference will occur? The in-phase / solarity that makes the food reach the lower limit of the maximum ice crystal generation area is modeled according to the type of food mouth, and when the type or size of the food is entered by the user / operating part, the most correct selection is made. Since the fast operation is performed at a set temperature of 50 ° C, the food can be reliably cooled below the lower limit of the maximum ice crystal generation region. In addition, if the temperature of the food is detected directly using infrared rays or the like, it can be cooled more reliably below the maximum ice crystal generation region. In addition, because it is controlled so as not to overshoot the lower limit of the maximum ice crystal generation region -30- 571066 hair quail_continued to buy (25) or more, it can be reliably maintained in the weak freezing temperature region. In addition, in the rapid freezing, the heating control is not implemented in accordance with the defrosting operation. Therefore, the rapid freezing can be preferentially performed even when the timing of the defrosting starts in the rapid freezing, thereby maximizing the freezing capacity. . In addition, in this embodiment, a description is given by taking a configuration in which a weak freezing chamber (106) is provided in the freezing chamber (108), but it is not limited to this, but the door leaf may be separated from the cold rolling chamber. The independent method may be a temperature switching chamber (15) that can be switched to a specific temperature region including a weak freezing temperature region. [Effects of the Invention] In summary, in terms of the ice making chamber, since the height of the ice cubes in the ice making chamber can be changed to be near the waistline of the user, it is not necessary to change the posture when using the ice cubes. Bend forward to easily remove ice cubes to improve the usability, and extend the passage even if the cold air from the freezing cooler located below the main body is introduced into the upper ice-making chamber section. The cooler and the cooling fan and the cold air channel or the return channel are arranged side by side on the back of the storage room, so that the shape of the back of the respective storage room can be flattened without damaging the internal volume efficiency of the refrigerator, so that the storage space can be realized. Use it effectively. On the other hand, in the cold-rolling room, because the food is controlled quickly and quickly passed through the largest ice crystal generation area and stored in a weak freezing temperature area, it will not damage the cell tissue of the food and will not cause the taste to deteriorate -31 -571066 Fat Ju says-buy (26) and keep it fresh.
