Description

电冰箱用真空保鲜箱 Refrigerator box with vacuum preservation

本实用新型涉及的是在电冰箱(柜)中设置一密封真空保鲜箱,用于延长各类食品的存放、保鲜期,弥补现有冰箱(柜)只冷藏不能真空保鲜。 The present invention relates to a seal disposed in the vacuum preservation refrigerator box (cabinet), the extension storing various types of food for preservation period, to compensate for the conventional refrigerator (cabinet) not only frozen vacuum preservation. 功能单一的不足。 Single function deficiencies.

食品的存放、保鲜方法主要有二种。 Food storage, preservation methods are mainly two kinds. 一是冷藏法,将食品置于一定的低温环境中抑制菌类的快速繁殖。 First, refrigeration method, the food placed in certain low-temperature environment to inhibit rapid propagation of fungi. 如把食品放在冰箱(框)中保存等。 As the food in the refrigerator (box) in preservation. 二是真空法,将食品放在密封的容器内,将其抽成接近真空状态进行保鲜。 Second, the vacuum process, the food placed in a sealed container, which is evacuated to near vacuum state to be fresh. 如软塑料真空封装袋等。 The soft plastic vacuum packaging bags. 但两种方法分别使用蔽病较大。 However, two methods were used large shield disease. 冰箱冷藏室内的温度约0℃左右,里面存放的食品时间稍长则变味、变质。 The temperature of the refrigerator compartment about 0 ℃, the food stored inside a little longer time then taste and deterioration. 真空封装的食品虽存放期较长,但一经启封,则失去了保鲜能力。 Vacuum packaging of food, although longer storage period, but once unsealed, then lost the preservation ability.

本实用新型的目的就是提供一种即冷藏又真空封装双倍功效的冰箱(柜)用真空保鲜箱。 The object of the present invention is to provide a vacuum packaged and refrigerated i.e. double the efficacy of the refrigerator (cabinet) with vacuum preservation tank. 即在电冰箱冷藏室中设置一个关启容易、自动控制的密封式真空保鲜箱。 I.e. easy to open is provided a refrigerating compartment in a refrigerator off, the automatic control box sealed vacuum preservation. 该保鲜箱的大小根据冰箱内的格局设计。 The size of the box is designed in accordance with the pattern of preservation in the refrigerator. 主要由箱体。 Mainly by the cabinet. 箱门(盖),微型电动机带动真空排气泵和传感控制系统组成。 Door (lid), a miniature motor driven vacuum pump control system and sensor. 届时只需将食物放在电冰箱内的保鲜箱中,卡紧密封门即可达到长期保鲜、反复使用的目的。 Then simply put fresh food in the refrigerator box, the card tightly closed doors to achieve long-term preservation, the purpose of repeated use. 此保鲜箱不需使用时。 This fresh boxes without the use of time. 可拔下电源插头,停止其系统工作,还可将其取出电冰箱外单独作为密封保鲜箱用。 Can unplug the system stops its work, it can also be taken out as a separate outer sealing refrigerator with storage bins.

此保鲜箱如由电冰箱(柜)制造厂的新产品开发项目中整体设计,专设一保鲜室,抽真空系统和控制系统则可移至电冰箱(柜)上的压缩机组和其它部件上联动,令电冰箱的使用功能更提高一步。 This fresh boxes as indicated by the refrigerator (cabinet) factory new product development projects in the overall design, a dedicated fresh food compartment, and a vacuum system can be moved to a refrigerator control system (cabinet) on the compressor and other components linkage, so refrigerators use more features to improve further.

本实用新型是这样实现的:注塑机制作一整体的塑料箱体与箱门(盖),箱体的框部有凹槽,凹槽内嵌有密封橡胶圈,以便关上箱门后保持其内、外密封。 The present invention is implemented as follows: injection molding machine made integral with the plastic box door (lid), the box frame portion with a groove, a groove embedded in a sealing rubber ring, so as to maintain within the closed door outer seal. 箱体上还设有一小隔离室,隔离室内安装抽真空系统的微型电动机带动的微型真空排气泵。 There is a small box on the isolation chamber, isolating the micro vacuum pump evacuated chamber mounted miniature motor driven system. 还安有检测控制系统的波纹管、按扭开关(也可用压力传感器检测控制)。 An bellows further detection control system, a switch button (detection control may also be used a pressure sensor). 隔离室与箱体有二个导通孔,其一安装一个只许空气单向流通的阀门,真空排气泵通过此单向阀门将保鲜箱内的空气抽出。 Isolation chamber and the tank has two vias, one can only install a one-way air flow valve, the vacuum pump fresh air drawn through this tank way valve. 另一孔上安一支波纹管,波纹管的一端封闭,另一端与箱体密封压接,封闭端顶住一按扭开关,作为检测保鲜箱内的真空状况、控制电动机电源的关断或接通。 An aperture on the other one of the bellows, the bellows is closed at one end, the other end of the housing seal crimped, closed end against a button switch, a vacuum condition detection preservation tank, controlling the motor supply is turned off or ON. 保鲜箱的箱门有锁紧卡,关上箱门则与箱体上的卡座卡紧,箱门上还有一个三通阀门,作用是当需取出保鲜箱内的食物时,先将其旋转90度,令箱内外气体流通、气压平衡,然后才易开启箱门。 Preservation box door with a locking card, close the door and the cabinet card deck tight when the door there is a three-way valve, when required to remove the effect of food preservation tank, first rotation 90 degrees, so that the gas flow inside and outside the tank, pressure balanced, easy to open before the door. 用后旋归原位。 After a spin in his own place. 总电源开关与电冰箱箱门上的电源开关并接,打开电冰箱的箱门则整个系统停止工作。 The main power switch and the power switch on the refrigerator door and then opens the door of the refrigerator to stop the whole system work. 微型电动机采用YYS10的交流电动机,真空排气泵采用小型滑动式空气压缩机,该类型压缩机的排气量公式如下:Vh=A×L×h×60(m3/h)A=2[πD2/8-πd2/8+de+2e(-t/2)]据上述公式计算,三公升容器的排气时间20分钟即可达到长期保鲜的真空度。 YYS10 miniature motor using the AC motor, a small vacuum pump slide-type air compressor, the displacement type compressor of the following equation: Vh = A × L × h × 60 (m3 / h) A = 2 [πD2 / 8-πd2 / 8 + de + 2e (-t / 2)] according to the above formula, three liters of gas by the container 20 minutes to achieve a degree of vacuum of long-term preservation.

本实用新型的具体结构由以下附图给出:图一是本实用新型的外观示意图。 The specific configuration of the present invention is given by the following figures: FIG. First, the external view of the present invention.

图二是本实用新型中隔离室的剖面示意图。 Figure II is a schematic cross-sectional view of the present invention in the isolation chamber.

下面结合附图进一步说明本实用新型提出的具体装置的细节及工作情况。 Further details of the specific apparatus of the present invention presented below in conjunction with the accompanying drawings and the work.

该装置包括箱体(1)、箱门(2),箱体(1)的边缘四框上有凹槽,槽内嵌有密封胶条(4),箱门(2)上有锁紧卡(5)和三通阀门(6)。 The apparatus includes a housing (1), door (2) with the housing (1) of the four edges of the frame groove, a sealing strip embedded grooves (4), door (2) has a locking snap (5) and a three-way valve (6). 关上箱门(2)后,卡紧锁紧卡(5),密封胶条(4)防止门缝漏气。 After closing the door (2), a card locked tight card (5), the sealing strip (4) to prevent leakage under the door. 三通阀门(6)是当你需取出保鲜箱内的食品时,先将其旋转90度这时箱外空气通过导通孔进入箱内,内、外气压平衡,否则很难将箱门(2)打开。 Three-way valve (6) is that when you need to remove food preservation tank, first the outer case which is rotated by 90 degrees into the air inside the box, the inner and outer pressure balance via the via hole, the door would be difficult ( 2) open. 用后旋归原位。 After a spin in his own place.

箱体(1)的上角部还设有一个小隔离室(3),隔离室(3)内装有微型电动机(7)、微型真空排气泵(8),微型真空排气泵的进气口通过单向阀门(9)与箱体(1)内导通,单向阀门(9)只允许箱体(1)内的空气向外排出而不可进气。 Case (1) of the upper corner portion also has a small isolation chamber (3), the separator chamber (3) with a built-in miniature motor (7), the micro vacuum pump (8), the micro vacuum pump via an air inlet way valve (9) and the tank (1) is turned on, the one-way valve (9) only in the exhaust air housing (1) is not outwardly intake. 隔离室(3)与箱体(1)另一个导通孔上装一个单端封闭的波纹管(10)和按扭开关(11),用来检测箱体(1)内的真空状态,关断或接通电动机(7)的电源,控制其工作。 Isolating chamber (3) of the box (1) further vias tops closed end of a single bellows (10) and a switch button (11) for detecting the vacuum in the tank (1), off power or electric motor (7) to control its operation. 其安装方法是:波纹管(10)的封闭端顶着按钮开关(11),电动机(7)的电源线与按扭开关(11)连接,非真空状态时按扭开关(11)为常开。 The method of installation is: the closed end of the bellows (10) against the push button switch (11), a motor (7) and the power supply line switch button (11) is connected to the non-vacuum state button switch (11) normally open . 随着真空系统工作,箱体(1)内的空气逐步排空,此时波纹管(10)被外部气压压缩,按扭开关(11)的手柄随其后缩而延伸,当箱体内的空气被排到设定的接近真空状态时,按扭开关(11)手柄完全伸出,此时的按扭开关(11)为关断,电动机(7)停止工作。 With the system operating vacuum, the housing (1) in the air gradually evacuated, then the bellows (10) is compressed outside air pressure, the switch button (11) followed by reduction with a handle extends, when the air in chamber when the near vacuum state, button switch (11) is discharged to set the handle fully extended, in this case the switch button (11) is oFF, the motor (7) is stopped. 取食物后,箱体(1)内、外气压平衡,波纹管(10)恢复原状态,按扭开关(11)又压缩为常开状态,电动机又开始运作。 After taking the food, the casing (1), an outer pressure balance, the bellows (10) to restore the original state, the switch button (11) and the compression is normally open, the motor operation began. 以上的功能也可用压力传感器及控制器代替。 Above functions can also be used instead of a pressure sensor and a controller. 隔离室(3)的电源通过插座(12)与电冰箱(柜)箱门上的电源开关并接,电冰箱的箱门关上是导通状态。 Isolating chamber (3) by a power outlet (12) of the power switch on the refrigerator door (cabinet) and then, the box is the refrigerator door conductive state. 打开电冰箱箱门,整个系统电源关断、不工作。 Opening the refrigerator door, the power off the whole system, does not work.
