生じていた。Conventional configuration and its problems Typical evaporator defrost heaters include pipe heaters and surface heaters, but pipe heaters have long pipes that make it easy to access the evaporator, so the pipes are long, so the heaters are difficult to use. The disadvantage is that it is difficult to handle and requires time and effort, such as inserting it into grooves previously provided in the fins and end plates of the evaporator after bending. In addition, since the surface heater has a planar shape (1), the surface blocks the air passage and the defrost water channel, so it has the disadvantage that it can only be used in evaporators with certain specific specifications. In particular, in an evaporator with a north landing, if a surface heater is installed, there is a drawback that a bypass air path cannot be provided to secure the air passage when the suction side of the cooled air is clogged with the cold air 211. was occurring.

防ぐことができるようにしたものである。Structure of the Invention In order to achieve this object, the present invention connects a part of the vertically elongated evaporator in the vertical ventilation passage on the ventilation passage suction side to a bypass air passage and one side of the evaporator on the opposite side of the pipe. By arranging the defrost surface heater to exchange heat with the evaporator, even if clogging due to frost occurs on the ventilation suction side of the evaporator, a bypass air path is secured and the amount of ventilation is ensured, preventing a decrease in performance. This is something that can be prevented.

ぞれもどされる。Reference numeral 8 designates a freezer compartment side suction port formed in the partition plate 4', and 9 represents a refrigerator compartment side suction port formed in the partition wall 4. In addition, reference numeral 10 denotes a bypass air passage formed in the partition plate 4' near the freezer compartment side suction port 8, which bypasses the ventilation suction side 6' of the evaporator 6. 11
is a fan duct that guides cold air to the freezer compartment 2 and refrigerator compartment 3. Therefore, due to the fan operation, the air in the freezer compartment 2 passes through the freezer compartment side suction port 8 9, and the air in the refrigerator compartment 3 passes through the refrigerator compartment side suction port 9, directly, and then via the bypass air path 10 to the evaporator. 6 and flows as shown by the arrow, and behind the fan 7, the fan duct 11 returns them to the freezer compartment 2 and the refrigerator compartment 3, respectively.

。On the other hand, the evaporator 6 is configured such that a refrigerant pipe 13 passes through a plate fin 12, and the entire evaporator 6 is formed vertically in accordance with the shape of the cooling chamber 5. A surface heater 14 is attached on the side opposite to the bypass air passage 10 for heat exchange with the fins 12, and is energized to remove frost when the evaporator 6 is defrosted.

に伴なってバイパス風路１ｏへの通風量が増加する。In the above configuration, the ventilated air is cooled by being ventilated from the bottom to the top as shown by the arrow in FIG. . Unfortunately, at this time, the frost on the evaporator 6 is on the ventilation suction side 6'.
It starts from the beginning and gradually progresses to the downstream side of the ventilation, that is, upward. As the ventilation passage on the ventilation suction side 6' is blocked by the clothing 1fi, the ventilation resistance thereof increases, and the amount of ventilation to the bypass air passage 1o increases accordingly.
