为了防止冷冻室侧冷气管100和冷藏室侧第一冷气管210的冷气相互进行交流,使冷冻室侧冷气管100和冷藏室侧第一冷气管210相互隔离。 To prevent freezing chamber and the refrigerating chamber side of the first side cold air pipe 100 air-conditioned cold air pipe 210 communicate with each other, so that the freezer side 100 and the cold side cold air pipe cool air duct 210 first isolated from each other. 所以本发明片管型蒸发器27的管27a由分区板90分成冷冻室侧冷气管100和冷藏室侧第一冷气管210,管27a的外周表面设置有散热片27b。 So-tube type evaporator tubes 27 of the present invention by a partition plate 27a and a refrigerating chamber side 90 into the freezing chamber cold air pipe 100 side of the first air-conditioning pipe 210, the outer peripheral surface of the tube 27a is provided with fins 27b.

冷冻室侧冷气的设定温度要比冷藏室侧的冷气设定温度低,所以在冷冻室侧冷气管100上散热片27b的个数要比在冷藏室侧第一冷气管210上的散热片27b的个数多。 Air-conditioning of cold air freezing chamber side than the set temperature side of the refrigerating compartment set temperature is low, so the freezer side 100 on the number of fins 27b than in the refrigerator compartment side of the first cool air duct 210 fin cool air duct The number of multi-27b.

具有上述结构的独立制冷型电冰箱通过压缩机的运转造成蒸发器27的热交换的环境,通过轴流扇105和热风扇205的运转,使箱内的冷气强制循环。 Independent refrigeration type refrigerator having the above structure causes the evaporator heat exchange environment 27 through operation of the compressor, axial flow fan operation by 105 and the hot air fan 205, so that the inside of the cold air forced circulation. 在冷冻室1内循环的冷气通过冷气吸入口103流入到冷冻室侧冷气管100,经过蒸发器27进行热交换,经蒸发器27进行热交换后的冷气经过排出口101排放到冷冻室,反复执行上述循环过程。 In the cold air circulating the freezing chamber 1 through the cold air suction port 103 side flows into the freezer compartment cool air duct 100, through the evaporator 27 exchanges heat, through air-conditioning evaporator 27 performs heat exchange through the discharge port 101 is discharged to the freezing chamber, repeatedly performing the above cycle.

另外,通过热风扇205的运转,使在冷藏室内循环的冷气通过冷气吸入口240吸入到冷藏室侧第一冷气管210,然后,经过蒸发器27进行热交换,经过热交换后的冷气在热风扇的作用下,通过冷气连接管230向冷藏室侧第二冷气管220流动,通过冷气排出口201排出到冷藏室2,反复执行上述循环过程。 Further, operation of the fan 205 by heat, so that the cold air circulated through the refrigerating compartment cold air suction port 240 to the suction side of the first refrigerating chamber cold air pipe 210, and then, through the evaporator 27 by heat exchange, the cold air after the heat exchange in the heat Under the effect of the fan, through the cool air flow pipe 220 connecting tube 230 to a second side of the refrigerating chamber cold air, through the cool air discharge port 201 is discharged into the refrigerating chamber 2, the above-described cycle is repeated.

因此,本发明独立制冷型电冰箱只用一个蒸发器也能充分的使冷冻室和冷藏室进行独立制冷。 Therefore, the independent refrigeration type refrigerator of the present invention only one evaporator can be sufficient to make the freezer and refrigerator independent refrigeration. 由于上述冷藏室侧冷气管内单独具备了热风扇,增加了在冷藏室循环冷气的风量。 Because of the above side refrigerator compartment with a separate fan in the air-conditioning heat pipe, increasing the circulation of cool air in the refrigerator compartment air flow.

此外,本发明独立制冷型电冰箱也可以具有如下结构:冷冻室侧冷气管和冷藏室侧冷气管不拘于分隔板的分隔,以分隔蒸发器的分区板为中心,将冷冻室和冷藏室的后面分离,所以上述冷藏室侧冷气管无需分成两个冷气管也可以形成相互独立的冷气流路,与冷冻室侧冷气管相同,冷藏室侧冷气管也位于冷冻室和冷藏室的后面,用送风扇替换轴流扇。 In addition, independent cooling type refrigerator of the present invention may also have the following structure: the freezer and refrigerator compartment side side cool air duct cold air tube confined in separate separation plate to separate the evaporator partition plate as the center, the freezer and refrigerator behind the separation, so the cool air duct above the refrigerator compartment side without cool air into the tube may be formed of two mutually independent air flow path, and the same side of the freezer cool air duct, air conditioning duct side refrigerator compartment is also located behind the freezer and refrigerator, Replace axial fan with a blower fan.
