本发明涉及冰箱的冷却储藏室，尤其是制冰室的结构及控制方法、弱冷冻室的控制方法。 The present invention relates to cooling a refrigerator storage compartment, the structure and control method of the ice making compartment in particular, the control method of the weak freezing chamber.
背景技术 Background technique
近年来，冰箱随着人们生活的多样化其容量呈大型化的趋势，从门的开关次数多、使用频度高考虑，在冰箱本体的上部配置容纳储藏物容积最大的冷藏室，其下部配置蔬菜室及冷冻室，同时大多在蔬菜室和冷冻室之间设置具有制冰装置的制冰室以及可将箱内温度从冷冻温度到蔬菜保存温度为止切换成多个温度带的温度切换室。 In recent years, with diversification of living refrigerator of large capacity as a trend, the number of switching from the multi-door, consider frequently used, arranged in an upper portion of the refrigerator body to accommodate the maximum refrigerating capacity stored products, the lower portion configured vegetable compartment and the freezer compartment, while most of the ice making chamber provided with an ice making apparatus and between the freezer compartment and a vegetable compartment inside temperature can be switched from the freezing temperature to the storage temperature of vegetables up into a plurality of temperature switching compartment temperature zone.
因为要设置多个储藏温度不同的储藏室，原来单一的冷却器变成各温度带专用的冷却器、比如冷冻温度用冷却器和冷藏温度用冷却器等二个冷却器分别与各自的温度室对应设置的结构。 Since a plurality of different settings to the storage temperature of the storage compartment, the cooler into the original single cooler temperature zone of each specific, such as the freezing temperature with the refrigerating temperature with the cooler and cooler respectively two respective temperature cooling chamber corresponding structures provided.
而且，这种具有多个冷却器的冷却方式中，为了提高储藏室的冷却效率，将与各储藏室温度对应的冷却器设置在该储藏室的背后等。 Moreover, this cooler having a plurality of cooling, in order to improve the cooling efficiency of the storage compartment, the storage compartment temperature corresponding to each cooler disposed behind the storage compartment and the like. 即，冷藏用冷却器配置在冷藏室的旁边，将比该冷藏室温度稍高的蔬菜室也靠近冷藏室配置。 That is, next to refrigeration cooler arranged in the refrigerating compartment, the refrigerating compartment temperature slightly higher than the vegetable compartment also arranged close to the refrigerating compartment. 冷冻用冷却器设置在冷冻室的背面部，同时，将成为冷冻室温度的制冰室及温度切换室也同样配置在冷冻室附近。 Freezing cooler portion provided on the back of the freezer compartment, while the temperature of the freezing compartment becomes ice compartment and the temperature switching compartment are also arranged in the vicinity of the freezing compartment. 这种形态称为第1形态。 This form is called the first aspect.
而在冷冻食品时，尽快通过食品的最大冰结晶生成带、即-1～-5℃，这样可不破坏食品的细胞组织和鲜度而进行冷冻保存。 And in the frozen food, the maximum ice crystal generating quickly with food, i.e., -1 ~ -5 ℃, this may damage cells and tissue of the fresh food and cryopreserved.
因此，用家庭用冰箱冷冻食品时，一般是通过提高冷冻循环的压缩机的转速等来增加冷冻能力，加快食品的冷却速度进行急速冷冻。 Therefore, when using household refrigerator frozen foods, freezing is generally to increase the capacity by increasing the speed of the compressor of a refrigeration cycle, and accelerate the rapid cooling rate of the food will be frozen. 但是，如食品温度在最佳保存的温度、比如-18℃以下，则会出现冰冻程度太厉害、肉及生鱼片等食品很难用刀切割的问题。 However, as the temperature of the food stored in the optimum temperature, such as less -18 ℃, the degree will be frozen too much meat and raw fish and other foods difficult to cut with a knife problem occurs.
对此，最近得知，如将食品的冷冻温度提高，在-7～-10℃(以下称为弱冷冻温度带)下进行冷冻保存，则虽然不能长期保存，但保存数周程度却没有任何问题，而且烹调时用刀切割方便，有人提出了一种冰箱，具有可切换至包括弱温度带在内的各种温度的切换室。 In this regard, recently learned, as will increase the temperature of the food frozen, at -7 ~ -10 ℃ (hereinafter referred to as weak freezing temperature) under cryopreservation, although it is not long-term storage, but stored for several weeks without any degree problem, but also easy to cut with a knife, a refrigerator has been proposed, having to switch to various temperatures including low temperature zone including switching cooking chamber.
该切换室可进行如下控制，即在室内温度相对目标设定温度太高时打开设置在冰箱后方的风门送入冷气，当室温低时用加热器加热以保持设定温度。 The chamber may be a control switch, i.e. the indoor temperature set relative to the target throttle opening is provided at the rear of the cool air into the refrigerator when the temperature is too high, the low temperature when heated by a heater to maintain the set temperature. 这种形态称为第2形态。 This form is called the second aspect.
但是，第1形态的冰箱，其制冰室配置在蔬菜室的下部，即使从冰箱整体的布局来看也位于下方，因此在取冰时身体要弯曲，夏季等频繁利用冰的时期尤其使用不方便。 However, the first aspect of the refrigerator in which ice making chamber disposed at a lower portion of the vegetable compartment, even if the entire refrigerator is also located below the layout view, and therefore when the harvest of the body to be bent, in particular during the summer season is frequently used without using an ice Convenience.
冰箱的外形尺寸由于日本国内厨房等设置条件的限制，其宽度、深度及高度都几乎达到了极限，因而储藏空间的扩大也受到限制，客户需要使用方便的要求越来越强烈。 Refrigerator dimensions due to the Japanese domestic kitchen set limits, the width, depth and height have almost reached the limit, and thus expand the storage space is limited, customers need easy to use and requires more and more intense.
而第2形态的冰箱，将没有冰冻的常温状态的食品放入设定在弱冷冻温度带的切换室内时，因该室内的温度高于比如-25℃的冷冻室温度，故食品温度通过最大冰结晶生成带的温度带需要较多的时间，成为所谓的缓慢冷冻。 When the refrigerator of the second aspect, the food is not placed in the frozen state at room temperature is set at low freezing temperature switching chamber due to a temperature higher than the room temperature such as -25 ℃ freezing chamber, so the maximum temperature of the food ice crystal formation temperature zone requires more time, a so-called slow freezing.
缓慢冷冻时，食品细胞组织被破坏、肉等的颜色发黑、蛋白质的自我分解和脂肪的氧化引起食品劣质。 When the slow freezing, the food is damaged tissue, such as meat color black, self-decomposition of protein and fat food inferior due to oxidation.
而且，在将比弱冷冻温度带的温度高的新食品放入时，随着室内温度上升，原已用弱冷冻温度带保存的冷冻食品的温度也随之上升，出现食品口味和鲜度下降的问题。 Moreover, at high temperatures than the freezing temperature with the weak into the new food, along with the indoor temperature rises, the already frozen food with a temperature preservation of weak freezing temperatures will also rise, food taste and freshness decline The problem.
本发明是为了解决上述问题而进行的，目的在于使第1形态的冰箱对应客户的多样化要求，通过将冷气管道机构及冷却机器对储藏室的有效配置，提供一种将制冰室配置在冷藏室空间一角的、使用方便的储藏室布局。 The present invention is made to solve the above problems, the object of the first aspect of the refrigerator corresponding to the diverse requirements of the customer, the cool air duct by the cooling means and effective allocation machinery storage compartment is provided an ice making compartment disposed corner of freezer space, easy to use storage room layout.
并使第2形态的冰箱提供一种在以弱冷冻温度带保存食品时不使食品鲜度和口味下降的冰箱的控制方法。 And the second aspect of the refrigerator is provided a method of controlling a refrigerator without food freshness and taste of a weak decrease in the freezing temperature range for preserving food.

急速制冰模式时，通过设在冰箱门表面的操作盘54的按钮操作等开始执行，将冷气挡板16完全打开，使制冰用风扇31高速旋转，并使送往制冰室的冷气量增加，一直持续到制冰结束或急速制冰模式解除为止。 When the rapid ice-making mode, started by the surface of a refrigerator door provided on an operation panel 54, a button operation or the like, the cold air flap 16 is fully opened and the fan 31 rotates at high speed ice-making, and the amount of cold air sent to the ice making chamber increase continued until the end of the ice or fast ice mode is canceled so far.
泵停止模式时，在对冷藏模式和冷冻模式进行切换时，关闭切换阀41，让压缩机40旋转规定时间，比如30秒，使残留在冷冻冷却器27内的制冷剂得到回收。 When the pump stop mode, when the freezing mode and a refrigeration mode switching, the switching valve 41 closed, so that the compressor 40 is rotated for a predetermined time, such as 30 seconds, and the residue is recovered in the refrigerant in the refrigerating cooler 27.
以下对各储藏室的冷却机构进行说明。 Hereinafter, each storage compartment cooling mechanism will be described.
由前述冷却器21、27冷却的冷气在其上部的冷藏用和冷冻用风扇22、28的各自作用下向各储藏室空间内吹出，吹出的冷气如箭头所示将各冷藏室冷却，然后从吸入口返回冷却器，重复这样的循环使各储藏室冷却到规定的温度并得以保持。 Each within the storage space of the blown air cooled chiller 21, 27 in its upper part with the refrigerating and freezing fans 22 and 28 under the action of a respective, blown cold air cooling the refrigerating compartment as shown in each arrow, then from return to the cooler air inlet, the cycle is repeated so that each storage compartment is cooled to a predetermined temperature and maintained.
冷藏室5中，来自冷藏用冷却器21的冷气在冷藏用风扇22的作用下其一部分向冷藏室的上面吹出，同时其他冷气分流至在冷藏室背面两侧形成的管路24中，并从在管路24上下方向按规定间隔穿设的冷气吹出口25吹向冷藏室内，在冷藏室内循环后的冷气从吸入口26返回冷却器21，冷气循环如此重复。 5, the refrigerating chamber, the cool air from the refrigerating cooler 21 under the action of the fan 22 is blown to the upper part of the refrigerating compartment in a refrigeration, air-conditioning while the other bypass line to the back surface is formed on both sides of the refrigerating compartment 24, and from 24 in the vertical direction line by a predetermined interval of cold air provided through the air outlet 25 is blown refrigerating room, the cooler 21 returns from the suction port 26 in the cold air circulating the refrigerating room, air circulation repeat.

冷冻空间的冷却控制基本与前述冷藏室控制相同，冷冻用冷却器27的冷气由冷冻用风扇28送至冷冻室9内，同时通过从冷冻室上部的蔬菜室7的背面中央向上方设置的送风管路30，被导向设在上部的冷藏室空间一角的制冰室12内。 Cooling the refrigerated space is substantially the same control and the control of refrigerating, freezing cooler 27 cool air is supplied to the freezing chamber 9 by the freezing fan 28, while disposed upwardly from the center of the back of the vegetable compartment through the upper portion of the freezing chamber 7 is sent air line 30, is guided to the upper portion of the refrigerating compartment space provided at a corner of the ice making chamber 12.
设在该制冰室背部的第3风扇、即制冰用风扇31的旋转使来自冷冻用风扇28的冷气的一部分吹至制冰室12内，而且一部分通过切换室管道32及冷气挡板16导入相邻的温度切换室15内并对其进行冷却。 Provided in the back of the ice making compartment fan 3, i.e. the rotation of the fan 31 the ice making portion of the cold air from the freezer fan 28 is blown into the ice making compartment 12, and a portion of the chamber by switching the air-conditioning duct 32 and the baffle 16 introduced adjacent temperature switching chamber 15 and subjected to cooling.

以下对本发明的一个变更例作说明。 Examples of a change to make the following description of the present invention.
(变更例1)图9是说明前述第1实施形态的管道结构的概要图，图10是变更例1的管道结构概要图。 (Modification 1) FIG. 9 is a schematic diagram illustrating a structure of a duct of the first embodiment, FIG. 10 is a schematic diagram of a duct structure changes.
本发明的第1实施形态如图9所示，从冷冻冷却器27生成的冷气由冷冻用风扇28经由冷气管道30向上方送风，并由制冰用风扇31吹向制冰室12内。 The first embodiment of the present invention shown in Figure 9, the cooler 27 from freezing cold air generated by the blower 28 to the top of the freezing air duct 30 via a fan, a fan 31 is blown by the ice within the ice making compartment 12. 如图10所示，由冷冻冷却器27生成的冷气由冷冻用风扇28吹向冷冻室9内，该冷冻室空间内的空气经由设在冷冻室后方的管路由制冰风扇31吹向制冰室12。 10, generated by the freezer cooler 27 by the cool air blown to the freezing chamber 28 within the freezer fan 9, air inside the freezing chamber via the space provided in the rear of the freezing chamber fan blowing pipe routing ice ice 31 room 12.
另外如图11所示，也可是由冷冻冷却器27所生成的冷气直接经由管路后由制冰风扇31吹向制冰室12。 Also shown in Figure 11, may also be frozen by the cold air generated by the cooler 27 is blown directly via the conduit 31 from the ice making compartment fan 12 ice. 在此场合下，可将冷冻用风扇28配置在冷冻冷却器27的下方，该结构可提高冷冻室9的冷冻能力并可靠地对制冰室进行冷却。 In this case, the freezer fan 28 may be disposed below the refrigerating cooler 27, the structure can increase the refrigerating capacity of the freezing chamber 9 and the ice making compartment reliably cooled.
(变更例2)自动制冰装置在制冰过程中，除了除霜模式外，要运转制冰用风扇31，。 (Modification 2) automatic ice making unit in the ice making process, in addition to the defrost mode, the fan 31 to the ice making operation ,.
进行除霜运转时，冷冻用冷却器27温度较高，如将该较高温度环境下的空气送风至制冰室12内的话会使室内温度显著上升，不仅制冰时间延长，而且储存的冰会融化。 When the defrosting operation, a high freezing temperature of the cooler 27, such as the ambient air blowing at higher temperatures to the ice making chamber 12 then causes a significant increase in the room temperature, not only prolonged ice, and stored ice will melt. 另外，冷藏模式时，尽管冷冻用冷却器27不被冷却，但冷却器温度保持在低温，通过运转制冰室风扇31使制冰室12继续冷却。 Further, when the cold storage mode, although freezing is not cooled by the cooler 27, the cooler temperature is maintained at a low temperature but, by operation of the ice making compartment fan 31 continues to cool the ice making compartment 12.
因此，除除霜模式以外，即使不是冷冻模式也运转制冰室风扇31，这样可缩短制冰时间、可靠地保持箱内温度。 Thus, in addition to the defrost mode, the operation mode can also if not frozen ice making compartment fan 31, so that the ice making time can be shortened, securely holding the internal temperature.
(变更例3)冷藏模式时，使制冰用风扇31低速运转，冷冻模式时，使制冰室风扇31高速运转。 When the cold storage mode (Modification 3), so that the ice making fan 31 at low speed, when the freezing mode, the ice making compartment fan 31 at high speed.
冷藏模式时，因冷冻冷却器27不被冷却，故无论制冰用风扇31高速旋转和低速运转，与通常的高速运转之差较小。 When the cold storage mode, by freezing cooler 27 is not cooled, so that regardless of the ice making fan 31 rotates at high speed and low speed, the difference is usually small and the high-speed operation. 因此，冷藏模式中使制冰用风扇31低速运转既可节电又能可靠地将制冰室12冷却。 Thus, the ice cold storage mode manipulation low speed fan 31 can be reliably saving both the ice making chamber 12 is cooled.
(变更例4)一旦用户利用操作盘54设定急速制冰模式，则进入任意规定时间比如8小时的急速冷冻模式。 (Modified Example 4) Once the user using the operation panel 54 to set the rapid ice-making mode, the process proceeds to an arbitrary predetermined time period such as 8 hours snap frozen mode. 制冰用风扇31高速运转，直到给水箱13的水用完，或检测出储冰量满了为止。 Ice fan 31 at high speed, up to a water tank 13 is used up, the amount of ice is detected or full. 这样可迅速、有效地制冰。 This rapid, efficient ice making.
(变更例5)一旦用户利用操作盘54设定急速制冰模式，则一旦将冷冻室9的设定温度定为比如-20oC，则规定温度下降比如3K。 (Modification 5) Once the user using the operation panel 54 to set the rapid ice-making mode, once the set temperature of the freezer compartment 9 is set at -20oC for example, such as the predetermined temperature drop 3K.
制冰用风扇31与压缩机41同步运转，一旦降低冷冻室9的设定温度，则实际的室内温度将高于设定温度，压缩机41为了提高冷冻能力而增加转速。 Ice fan 31 and the synchronous operation of the compressor 41, once the set temperature of the freezing chamber 9 is reduced, the actual indoor temperature above the set temperature, the compressor 41 is increased in order to improve refrigerating capacity speed. 因而与压缩机41同步运转的制冰风扇31的转速也自动增加，冷冻能力提高使制冰迅速进行。 41 and thus the synchronous operation of the compressor 31 of the ice making fan automatically increases the rotational speed, the refrigerating capacity improving the ice quickly.
(变更例6)制冰动作停止时，调节制冰用风扇31的转速，以保持制冰室12的室内温度。 (Modification 6) when the ice making operation is stopped, adjust the speed of fan 31 with ice to maintain the indoor temperature of the ice making compartment 12. 即，制冰动作停止中，只要保持储存的冰不融化即可，故可降低制冰风扇31的转速以有效地对制冰室12冷却，很好地保存冰，并有效地运转制冰用风扇31，以节省电力。 That is, the ice making operation is stopped, as long as they can be stored in the ice does not melt, it can reduce the rotational speed of the ice making fan 31 to efficiently cool the ice making compartment 12, well preserved ice, and ice-making operation effectively fan 31, to save power. 此时，制冰室内温度为低温时也可停止制冰用风扇31。 At this time, the ice making room temperature is a low temperature ice-making fan 31 may be stopped.
(变更例7)泵停止模式时使制冰用风扇31运转。 (Modified Example 7) an ice making fan pump 31 when the operation stop mode. 泵停止是在切换冷却模式时进行的，最好将冷冻用冷却器27的制冷剂尽快地回收至压缩机41。 Stopping the pump is in the cooling mode switch, preferably the frozen recovered refrigerant cooler 27 to the compressor 41 as soon as possible. 通过运转制冰用风扇，可增加冷冻空间的空气与冷冻用冷却器的热交换量，故可迅速回收制冷剂。 By the operation of the ice making fan, air can be increased and the freezing refrigerated space in heat exchange cooler, so the refrigerant can be quickly recovered.

冷藏模式用于将冷藏空间130的温度保持在规定的设定温度，当冷藏空间温度上升至大于设定值时，切换三通阀122，使制冷剂从冷藏毛细管123流入R蒸发器110侧，将通过蒸发产生的冷气导入冷藏空间130以将室内冷却。 The temperature of the cold storage mode for refrigerated space 130 is maintained at a predetermined set temperature, refrigerated space when the temperature rises to greater than a set value, the three-way valve 122, refrigerant 123 flows into the R evaporator 110 side from the refrigerator capillary, the cool air generated by the evaporator 130 to be introduced into the refrigeration room cooling space. 蒸发气化的制冷剂要返回压缩机115，但冷藏模式时，为了使制冷剂不流入比R蒸发器110蒸发温度低的F蒸发器112内而再次冷凝，在F蒸发器112侧的流道上装单向阀117。 Evaporated and gasified refrigerant returns to the compressor 115, but the cold storage mode, the refrigerant does not flow to the ratio R 110 is evaporated in the evaporator 112 F lower temperature evaporator and condensed again, the flow path in the evaporator 112 side F coat one-way valve 117.
在R蒸发器110的冷却过程中，在切换制冷剂流路的同时驱动R风扇111，将冷气吹入冷藏空间130内对室内进行冷却。 During cooling the R evaporator 110, while switching the refrigerant flow path R driven fan 111, cool air is blown into the refrigerated space 130 to chamber cooling.
冷冻模式在冷冻空间140的温度高于设定温度时启动。 Freeze mode is activated when the temperature of the refrigerated space 140 higher than the set temperature. 该模式通过三通阀122将制冷剂流路进行切换，使制冷剂流入冷冻毛细管124内，在F蒸发器112蒸发并通过蓄能器116和单向阀117返回压缩机115，形成制冷循环。 This mode switching three-way valve 122 through the refrigerant passage, the refrigerant flows into the freezer capillary tube 124, the evaporator 112 in the F evaporator and the accumulator 116 through check valve 117 and returned to the compressor 115, the refrigeration cycle is formed.
在对F蒸发器冷却的冷冻模式时，在切换制冷剂流路的同时以通常的转速运转F风扇113，以对箱内进行冷却。 When the F evaporator for cooling freezing mode, while switching the refrigerant flow path F at a normal speed operation of the fan 113 to be cooled on the inside.
关于将安放在弱冷冻室内的食品保存在弱温度带(-5至-10℃)的情况，根据图16和图17的流程图进行说明。 Food placed on the weaker stored in the freezer compartment temperature zone where the weak (-5 to -10 deg.] C), and 16 described with reference to the flowchart of FIG. 17 and FIG.
在步骤1(S1)中，将常温的食品放入弱冷冻室106的容器139内并关上门，客户通过操作部118对食品的保存温度进行指示(S2)。 In step 1 (S1), the ambient temperature of the food placed in the freezer compartment of the container 139,106 weak and close the door, the customer instruction (S2) through the operation unit 118 storage temperature of the food. 该保存温度设定在能用刀容易切割食品的弱冷冻温度带即-5至-10℃之间，这里设定为-8℃。 The storage temperature is set between the knife can easily cut the food that is frozen temperature zone of weak -5 to -10 ℃, here it is set to -8 ℃.
步骤3，客户将操作部118的弱冷冻开关放在开(ON)的状态。 Step 3, the client weakly frozen on the switch operating portion 118 is open (ON) state. 这样，控制部164将冷冻循环切换至冷冻模式，F风扇113以比通常高的转速旋转，而且S风扇142也旋转。 Thus, the control unit 164 switches the refrigerating cycle to the freezing mode, generally higher than 113 to the rotational speed of the fan F, and S fan 142 also rotates.
然后，打开挡板137，将F蒸发器112的冷气供给弱冷冻室106，如图16所示，进行急速冷冻运转(S4)，直到弱冷冻室内的食品温度降至比最大冰结晶生成带的下限值低的设定温度、本例为-10℃为止。 Then, the shutter 137 is opened, the cool air of the evaporator 112 F supplied weak freezing chamber 106, as shown in Figure 16, a rapid freezing operation (S4), until the temperature of the food freezer compartment weak drops below the maximum ice crystal formation zone low temperature lower limit value, in this case up to -10 ℃. 此时加热器143不通电。 At this time, the heater 143 is not energized.
进行急速冷冻运转时，安放在容器139内的食品被冷却，且快速通过食品水分最容易冰冻的温度带、即-1～-5℃的最大冰结晶生成带，所以能在保住食品的口味和鲜度的前提下冻结食品。 When rapid freezing operation, the container 139 housed within the food product is cooled, water and food by rapid freezing temperature zone most easily, i.e. the maximum ice crystal formation -1 ~ -5 ℃, it is able to keep the food taste and frozen food premise freshness.
继续急速冷冻运转，当S传感器141检测的食品温度降至-10℃以下时，停止急速冷冻运转，在-10℃以上时则继续步骤4的急速冷冻(S5)。 Continuing the rapid refrigerating operation, when the product temperature sensor 141 detects the S drops below -10 ℃, rapid freezing operation is stopped, at least -10 ℃ rapid freezing step is continued (S5) 4 in.
在步骤6，关闭挡板137并停止S风扇142，对加热器143加热。 In step 6, the closure flap 137 and fan 142 stop S, the heater 143 is heated. 此时，进行PID控制，使不要超过-5℃。 In this case, PID control, so that not more than -5 ℃. 该PID常数最好设定得不要超过到达目标温度的时间。 The PID constants set the best time not to exceed the target temperature is reached. 如图5所示，一旦食品温度上升至-8℃，则停止加热器143(S7)，然后开闭挡板137，将箱内温度保持控制在-8℃(S8)。 5, once the temperature of the food rises to -8 deg.] C, the heater is stopped 143 (S7), and then opening and closing the shutter 137, the chamber temperature control maintained at -8 ℃ (S8).
这样，进行急速冷冻运转，快速通过最大冰结晶生成带，食品不损失口味和鲜度，然后用弱冷冻温度带保存，能将食品以易切的状态冷冻保存。 In this way, rapid freezing operation, the maximum fast ice crystal formation, without loss of food freshness and taste, and then stored frozen temperature zone with a weak, easily able to cut food cryopreserved state. 此时，已保存在弱冷冻室内的食品会冷却至比弱冷冻温度带低的温度，但暂时的温度下降不会对食品的鲜度和口味有任何影响，可进行良好的保存。 At this point, it has been kept in the freezer compartment of a weak food will be cooled to freezing temperature than weak with low temperatures, but temporary drop in temperature will not have any impact on the freshness and taste of food can be good save.
即使在冷冻空间140内设置弱冷冻室106，也能通过对底面的加热器143加热来使温度容易上升至弱冷冻温度带。 Even weak freezing chamber 106 is provided in the refrigerated space 140, but also through the bottom surface of the heater 143 is heated to the temperature is likely to rise to weak freezing temperature.
急速冷冻运转一直进行到温度低于最大冰结晶生成带的下限值规定温度的时候，故即使是肉块等体积大的食品，也能冷却到最大冰结晶生成带以下，无论食品体积如何，都能均匀地良好地保存食品的鲜度和口味。 Rapid refrigerating operation is carried out until when the predetermined temperature is below the lower limit temperature of the maximum ice crystal formation, so even bulky pieces of meat and other food can also be cooled to the maximum ice crystal formation, regardless of the volume of food, can save uniformly good freshness and taste of food.
急速运转可能使食品温度与箱内温度产生差异，但只要事先针对食品的种类和大小，预先测定箱内温度与食品温度的温度差，并将可使食品达到最大冰结晶生成带的下限值的箱内温度按食品的种类和大小确定好，则一旦客户通过操作部将食品的种类和大小输入，并选择最确切的设定温度进行急速运转，就能可靠地将食品冷却至最大冰结晶生成带的下限值以下。 Fast food operation may cause a difference in temperature and the inside temperature, but the temperature for as long as the type and size of the food in advance, and the internal temperature measured in advance and the difference between the temperature of the food, and the food can reach the lower limit of maximum ice crystal formation zone good interior temperature determined by the type and size of the food, once the client and the size of the input type of food, and choose the most exact temperature setting operation through the operation unit rapidly, the food can be cooled reliably to the maximum ice crystal generating a lower limit value of the tape. 另外，如利用红外线传感器等直接检测食品温度，则能更可靠地冷却至最大冰结晶生成带以下。 Further, as temperature of the food is directly detected using an infrared sensor, it is possible to more reliably cooled to less maximum ice crystal formation.
另外，由于控制加热器，使不要超过最大冰结晶生成带的下限值，能可靠地保持弱冷冻温度带。 Further, since the control of the heater, so that not more than the lower limit of the maximum ice crystal formation zone, can be securely held weakly freezing temperature.
而且，在急速冷冻运转中不进行除霜运转加热，即使在急速冷冻中到了应该开始除霜的时刻，也可优先进行急速冷冻，可最大限度地发挥冷冻能力。 Moreover, without the rapid freezing defrosting operation in heating operation, even if the time should start to defrost in the blast chiller, the priority may be rapidly frozen, freeze maximize capacity.
本发明的实施形态是将弱冷冻室106设在冷冻室108内，但并不局限于此，也可与冷冻室分离并独立设门，也可以是能够切换至包括弱冷冻温度带的规定温度带的温度切换室15。 Embodiment of the present invention is to weak freezing chamber 106 is provided in the freezing chamber 108, but is not limited thereto, and may be separated from the freezer compartment door is provided independently, it may be able to switch to include a predetermined temperature of freezing temperature zone weak 15 with the temperature switching compartment.
发明效果综上所述，制冰室的取冰位置在用户的腰部附近，使用冰时身体不必向前倾就可容易地取出冰，使用方便，同时即使要设置将位于本体下方的冷冻用冷却器的冷气导入上方制冰室部的管路，通过将冷冻用冷却器和冷却风扇、冷气管路和返回管路并设在储藏室的背面，也可不损害箱内的容积效率，并且能使各储藏室背面形状平坦化，有效利用安放空间。 Effect of the Invention As described above, the position of the harvest the ice making chamber near the user's waist, the body does not have to use the ice can be easily taken out of ice forward, easy to use, and to set the even positioned beneath the frozen cooling body the cool air is introduced into the ice making compartment portion above the line, by freezing cooler and cooling fans, the cold air conduit and the return conduit is provided on the back surface and the storage compartment, the volumetric efficiency may not damage the tank, and can each storage compartment is flattened back surface, the effective use of mounting space.
另外，由于是在弱冷冻室将食品急速冷冻，并快速通过最大冰结晶生成带后用弱冷冻温度带保存，不会破坏食品的细胞组织，因此能保持原味，以新鲜状态保存。 Further, since the weak snap frozen food freezer compartment, and after storage with fast through the maximum ice crystal formation weak freezing temperature without damaging the tissue of food, it is possible to preserve the original flavor, fresh state save.
