Description

具有变温和/或真空保鲜系统的冰箱及其控制方法 Varying temperature and / or refrigeration system and a control method of vacuum preservation

技术领域 FIELD

[0001] 本发明涉及一种冰箱,特别是涉及一种具有变温和/或真空双重保鲜系统的冰箱,另外,本发明还涉及一种具有变温和/或真空双重保鲜系统的冰箱的控制方法。 [0001] The present invention relates to a refrigerator, and more particularly to a refrigerator having a variable temperature and / or vacuum preservation dual system, further, the present invention further relates to a control method having a variable temperature and / or vacuum double preservation system of a refrigerator.

背景技术 Background technique

[0002] 在保鲜技术研究中,新鲜食品难以长久保存的原因主要是,存放食品温度会自行不断升高,湿度加大,以及气压有利于有害细菌的生长、繁殖,但在低温、低压条件下,既能杀灭或抑制霉菌、真菌生存,能抑制存放新鲜食品(如植物类,肉类)的呼吸,防止脱水、霉变。 [0002] In the study preservation technology, the reasons for long-term preservation of fresh food is difficult mainly, food storage temperature will continue to rise on their own, to increase humidity, and barometric pressure in favor of harmful bacteria growth, reproduction, but at a low temperature, low pressure conditions , kill or inhibit both molds, fungi survive, can be suppressed breathe fresh food storage (e.g., plants, meat), to prevent dehydration, mildew.

[0003] 现有技术的应用是将变温空间与真空保鲜空间分开在两个空间,变温单独作为一个功能区,真空保鲜单独作为一个功能区,用户需要根据自己对于不同食品的要求在不同的空间间室进行所需要的功能,而且两个功能占有两个空间,也是比较浪费的。 [0003] Application of the prior art is to temperature change space and vacuum space preservation separated two spaces, the temperature change as a separate functional areas, vacuum preservation as a separate functional areas, the user needs according to their different food products require different space between the chamber desired function, and both functions occupy two spaces, but also more wasteful.

[0004] 另外,如果用户对于某些食品的储藏可能在需要变温的同时,也需要真空保鲜的储藏,目前的功能排布不能使用户方便的同时享受这些功能。 [0004] In addition, if the user may also need to change the temperature, but also the need for storage of vacuum preservation of certain food storage, the current arrangement can not function enables users to conveniently enjoy these features.

[0005] 对比文件专利号200720037^9. 2,实用新型名称是冰箱真空保鲜盒,专利权人合肥美菱股份有限责任公司。 [0005] comparative file patent No. 200 720 037 ^ 9.2, is the name of the utility model refrigerator crisper vacuum, the patentee Hefei Meiling Co., Ltd. 其公开了一种冰箱真空保鲜盒,设置在冰箱冷藏室内,由盒体和盒盖构成的密闭盒,盒盖的背部设置抽气孔,所述密闭盒置于冰箱间室内。 Which discloses a refrigerator crisper in vacuo, provided the refrigerator chamber, the closed box and composed of a cover box body, a suction hole provided in the back cover, the closed cassette is placed between the refrigerator chamber. 这种结构的冰箱真空保鲜盒的温度不能调节,无法满足用户根据不同食物不同需选择不同低温进行真空保鲜的要求,达不到人性化的要求。 Temperature of the refrigerator crisper vacuum can not be adjusted to such a configuration, can not meet the needs of different users select different low temperature vacuum preservation according to the different requirements of the food, not meet the requirements human.

[0053] 参见图3所示的冰箱保鲜功能选择面板图,①、②、③、④表示的四种不同温度Tl、 T2、T3和T4,中间三个指示灯分别是低温选择正常运行指示(绿色)、真空选择正常运行指示(绿色)、故障报警指示(红色),右侧是START和OFF键。 [0053] The functions shown in refrigerator fresh selection panel FIG see FIG. 3, ①, ②, ③, four different temperatures Tl ④ represented, T2, T3 and T4, respectively, the middle three lights indicate normal operation to select a low temperature ( green), indicating normal operation of the vacuum select (green), fault alarm indication (red), and the right is OFF key START.

[0054] 参见图4为本发明所述的具有变温和真空双重保鲜系统的冰箱的控制方法,为本发明冰箱保鲜控制方法的最佳实施例,与图2所示的本发明冰箱结构实施例配合使用。 [0054] Referring to Figure 4 having varying temperature control method of double vacuum preservation system of a refrigerator according to the present invention, a preferred embodiment of the control method of the refrigerator preservation of the present invention, embodiments of the present invention, the structure of the refrigerator shown in FIG. 2 With the use of.

[0055] 该控制方法包括如下步骤: [0055] The control method comprises the steps of:

[0056] A、选定变温和真空双重保鲜功能; [0056] A, the selected variant vacuum double mild preservation of function;

[0057] B、进行变温选择; [0057] B, for variable temperature selection;

[0058] C、风门打开,制冷输入至保鲜抽屉; [0058] C, damper opening, the refrigerant is input to the drawers;

[0059] D、温控传感器进行检测,达到设定温度,风门关闭; [0059] D, the thermal sensor detects reaches the set temperature, the damper is closed;

[0060] E、自动启动真空泵,对保鲜抽屉进行抽真空; [0060] E, automatic vacuum pump, for evacuating drawers;

[0061] F、对保鲜抽屉内压力进行检测,达到设定压力,真空泵停止工作。 [0061] F, a pressure of the drawers is detected, reaches the set pressure, the vacuum pump is stopped.

[0062] 具体地,冰箱有冷藏室、冷冻室和变温室,变温和真空保鲜系统包括变温系统和真空系统,低温保鲜和真空保鲜做成一个空间设在同一隔层中。 [0062] Specifically, the refrigerator, a refrigerator, freezer and the temperature changing, becomes gentle vacuum preservation system comprises a variable temperature and vacuum systems, and cryogenic preservation of fresh make a vacuum space provided in the same compartment.

[0063] 用户选择变温度的功能区间,每个功能对应有Tl,T2,T3,T4不同的温度。 [0063] The user selects the function of the transition temperature range, corresponding to each function has Tl, T2, T3, T4 different temperatures. 用户根据储存不同的食品选择不同的低温温度,低温保鲜系统根据用户不同的温度选择进行制冷输入,以保证对于存放的蔬果有一个相对较低的温度,一段时间以后,温度达到要求的Tl 或T2或T 3或T4,温控感应器反馈信号,连接风门关闭; The user selects a different store different food cryogenic temperatures, cryogenic preservation system for cooling a user to enter different temperature selected according to the stored fruits and vegetables in order to ensure for a relatively low temperature, after a period of time, to achieve the required temperature Tl or T2 or T 3 or T4, temperature control sensors and feedback signals, connection damper is closed;

[0064] 此时,冰箱控制系统给真空保鲜系统一个信号,真空泵自动开启,对这个空间进行抽真空,持续一段时间,压力传感器检测此时保鲜抽屉的气压值,使得该空间的气压低于一个大气压,比如0. 7-0. 08atm,保持一个相对的真空度,如果达到压力设定的要求,真空泵停止工作,使得存放的东西可以在这个较低的氧气空间里面相对持久保存。 [0064] At this time, the control system for vacuum preservation refrigerator system signal, automatically turn on the vacuum pump for evacuating the space for a period of time, a pressure sensor for detecting the pressure value at this time of the drawers, so that a pressure of the space below atmospheric pressure, for example 0. 7-0. 08atm, maintaining a relative degree of vacuum required set pressure is reached, the vacuum pump is stopped, so that the stored things may be relatively persistent in the space inside this lower oxygen.

[0065] 由于向抽屉内收放或取出食品而使抽屉内的压力变得比规定值高的场合,经压力传感器检测抽屉内的压力值不在0. 7-0. OSatm范围内时,再次利用真空泵的驱动来抽吸空气进行减压,直到压力达到规定值以下。 [0065] Since the pressure in the extraction or retraction of the food drawer becomes higher than the predetermined value into the case of a drawer, the drawer the pressure sensor detects the pressure value is not 0. 7-0. OSatm within range, again using the driving a vacuum pump to pump air under reduced pressure, until the pressure reaches a predetermined value or less. 在压力检测步骤中,优先是是使用压力传感器进行压力检测,另外真空压力检测装置也可以采用计时器,通过启动真空泵的时间和真空泵抽真空的流速来计算变温真空系统的压力值。 A pressure detecting step, priority yes pressure sensor detects a pressure, the vacuum pressure detecting means may additionally be used a timer to calculate the pressure variable temperature vacuum system through the vacuum pump time values ​​and the flow rate of a vacuum pump.
