因此，本发明所涉及的冰箱的特征在于，所述冰箱包括箱体和设置于所述箱体内的冷藏室蒸发器，所述冷藏室蒸发器包括传热板以及蒸发管，所述蒸发管设置在所述传热板上，并经由所述传热板而吸收来自所述箱体的热量，所述蒸发管包括水平走向的蛇形蒸发管和垂直走向的倒U型蒸发管，所述蛇形蒸发管和所述倒U型蒸发管串联连接。Therefore, the refrigerator according to the present invention is characterized in that the refrigerator includes a box body and a refrigerating room evaporator arranged in the box, the refrigerating room evaporator includes a heat transfer plate and an evaporating tube, and the evaporating tube is arranged On the heat transfer plate and absorb the heat from the box through the heat transfer plate, the evaporator tubes include horizontal serpentine evaporator tubes and vertical inverted U-shaped evaporator tubes. The evaporating tube is connected in series with the inverted U-shaped evaporating tube.

根据上述的本发明所涉及的冰箱，由于制冷剂在流入到倒U型蒸发管时，一部分制冷剂因重力作用而发生回流，因而增加了冷藏室蒸发器中的制冷剂蒸发量。由此，能够吸收更多的热量，并能够提高冷藏室蒸发器的制冷能力。According to the above-mentioned refrigerator of the present invention, when the refrigerant flows into the inverted U-shaped evaporating tube, a part of the refrigerant flows back due to the action of gravity, thereby increasing the evaporation amount of the refrigerant in the evaporator of the refrigerating chamber. Thereby, more heat can be absorbed, and the cooling capacity of the evaporator in the refrigerator compartment can be improved.

另外，在上述的本发明所涉及的冰箱中，所述冰箱还包括：温度测量部，设置在所述传热板上，用于测量所述冷藏室蒸发器的温度；温度控制器，控制所述冷藏室蒸发器的温度；以及温控套管，连接所述温度测量部和所述温度控制器。In addition, in the above-mentioned refrigerator according to the present invention, the refrigerator further includes: a temperature measuring part, arranged on the heat transfer plate, for measuring the temperature of the evaporator in the refrigerating room; the temperature of the evaporator in the refrigerating room; and a temperature control sleeve connecting the temperature measuring part and the temperature controller.

具体实施方式 Detailed ways

以下，参照附图，对本发明所涉及的冰箱100的最佳实施方式进行详细的说明。Hereinafter, preferred embodiments of the refrigerator 100 according to the present invention will be described in detail with reference to the drawings.

图2为表示本实施方式所涉及的冰箱100的大致结构的立体图。如图2所示，冰箱100包括箱体80和设置于箱体80内的冷藏室蒸发器90。冷藏室蒸发器90具备传热板10和蒸发管20。蒸发管20设置在传热板10上，并经由传热板10而吸收来自箱体80的热量。蒸发管20包括水平走向的蛇形蒸发管40和垂直走向的倒U型蒸发管30，蛇形蒸发管40和倒U型蒸发管30串联连接。FIG. 2 is a perspective view showing a schematic configuration of refrigerator 100 according to the present embodiment. As shown in FIG. 2 , the refrigerator 100 includes a box body 80 and a refrigerating room evaporator 90 disposed in the box body 80 . Refrigerating room evaporator 90 includes heat transfer plate 10 and evaporator tube 20 . The evaporation tube 20 is disposed on the heat transfer plate 10 and absorbs heat from the box body 80 through the heat transfer plate 10 . The evaporating tube 20 includes a horizontal serpentine evaporating tube 40 and a vertical inverted U-shaped evaporating tube 30 , and the serpentine evaporating tube 40 and the inverted U-shaped evaporating tube 30 are connected in series.

如以上所述，由于制冷剂在流入到倒U型蒸发管30时，一部分制冷剂因重力作用而发生回流，因而增加了冷藏室蒸发器90中的制冷剂蒸发量。由此，能够吸收更多的来自箱体80的热量，并能够提高冷藏室蒸发器90的制冷能力。As mentioned above, when the refrigerant flows into the inverted U-shaped evaporator tube 30 , a part of the refrigerant flows back due to the action of gravity, thereby increasing the evaporation amount of the refrigerant in the evaporator 90 of the refrigerator compartment. Thereby, more heat from the box body 80 can be absorbed, and the cooling capacity of the refrigerating room evaporator 90 can be improved.

另外，在传热板10上设置有用于测量冷藏室蒸发器90的温度的温度测量部50，温度测量部50经由温控套管60而连接于温度控制器70。温度控制器70基于温度测量部50所测量出的温度，对冷藏室蒸发器90的温度进行控制。In addition, a temperature measurement part 50 for measuring the temperature of the refrigerating room evaporator 90 is provided on the heat transfer plate 10 , and the temperature measurement part 50 is connected to the temperature controller 70 through the temperature control sleeve 60 . Temperature controller 70 controls the temperature of refrigerator compartment evaporator 90 based on the temperature measured by temperature measuring unit 50 .

温度测量部50优选为以与倒U型蒸发管30平行的方式设置在倒U型蒸发管30的附近。这样，由于利用倒U型蒸发管30而提高了冷藏室蒸发器90的制冷能力，因此，平行设置在倒U型蒸发管30的附近的温度测量部50的温度测量变得稳定。The temperature measuring part 50 is preferably disposed near the inverted U-shaped evaporating tube 30 in parallel with the inverted U-shaped evaporating tube 30 . In this way, since the cooling capacity of the refrigerating room evaporator 90 is improved by using the inverted U-shaped evaporating tube 30 , the temperature measurement of the temperature measuring unit 50 arranged in parallel near the inverted U-shaped evaporating tube 30 becomes stable.

以上，对本实施方式所涉及的冰箱100进行了说明，但是，本发明所涉及的冰箱并不限于上述的实施方式，本领域技术人员在不偏离本发明的实质精神和范围的情况下可以根据需要对本发明进行变形和变化。这些变形和变化均落入本发明的范围内。The refrigerator 100 according to the present embodiment has been described above, but the refrigerator according to the present invention is not limited to the above-mentioned embodiment, and those skilled in the art can make Modifications and variations are made to the invention. These modifications and changes all fall within the scope of the present invention.

例如，在上述的实施方式中，设置有1个倒U型蒸发管30，但是，为了更好地提高制冷能力，也可以设置2个以上的倒U型蒸发管，该2个以上的倒U型蒸发管串联连接。For example, in the above-mentioned embodiment, one inverted U-shaped evaporating tube 30 is provided. However, in order to better improve the refrigeration capacity, more than two inverted U-shaped evaporating tubes can also be provided. The evaporator tubes are connected in series.
