７の本来の冷却機能に障害を及ぼす危険性があった。However, while the blower 9 is stopped, the cold air generated in the cooler 8 accumulates in the lower part of the refrigerating compartment suction air passage 19 and finally flows into the compartment 11 from the compartment suction air passage 21. Therefore, the food in the compartment 11 may be overcooled and frozen even though the temperature inside the compartment 11 is controlled to a predetermined temperature by the damper thermostat 13. Further, even when the blower 9 is in operation, when the cool air is supplied only to the refrigerating compartment 7 by the control of the thermostats 12 and 13, the cool air returning to the cooler 8 through the refrigerating compartment suction air passage 19 is in the middle of the compartment. Compartment 1 from suction air passage 21
It sometimes flowed into 1. In particular, when the compartment temperature is set to a temperature range lower than the refrigerating compartment temperature (3 to 10 ° C.) (for example, −3 to 0 ° C.), the compartment temperature flows and the capacity and load are large. When the cold air that has sufficiently exchanged heat with the indoor parts flows into the refrigerating room suction air passage 19, it is approximately 5 to 10
The temperature rose to 0 ° C., which sometimes flowed into the compartment 11. Then, the dew condensation phenomenon occurs due to the fact that the compartment temperature is raised and the food is adversely affected, and the cool air in the minus temperature zone in the compartment 11 and the cool air in the plus temperature zone of the refrigerating compartment suction air passage 19 join together. There is a risk that the opening of the compartment suction air passage 21 may be blocked due to the development of ice, or the refrigeration compartment suction air passage 19 may be obstructed to impair the original cooling function of the compartment 11 or the refrigeration compartment 7. .
発明の目的 本発明は上記の点に鑑み、区画室吸込風路における氷結
を防止することを目的としている。SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object thereof is to prevent freezing in the compartment suction air passage.

In addition to blocking the backflow of cool air from the container to the compartment, the warm air flowing into the compartment from the refrigerating chamber suction air passage while the blower is operating also prevents damming and icing.

る。Description of Embodiments An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3.
A description will be given with reference to FIGS. The same parts as those of the related art are designated by the same reference numerals and the description thereof will be omitted. In the figure, reference numeral 21 'denotes a compartment suction air passage of the compartment 11 which penetrates the heat insulating material 20 and communicates with the refrigerating compartment suction air passage 19 to join the refrigerating compartment suction air passage 21'. It is surrounded by a weir 22 projecting into the air passage and a partition portion 22 ′ between the freezer compartment suction air passage 18 and the refrigerating compartment suction air passage 19. The weir 22 has a substantially L-shaped contact portion 22a in which the refrigerating compartment suction port 23 side is in contact with the top surface of the refrigerating compartment suction air passage 19 and the refrigerating compartment suction air passage 19 on the cooler 8 side. It is composed of a protruding portion 22b protruding at a height.

様の効果が得られる。Further, during operation of the blower 9, most of the cool air flowing from the refrigerating compartment suction port 23 toward the compartment suction air passage 21 ′ flows along the contact portion 22 a to the cooler 8, so that the compartment The phenomenon of dew condensation and icing around the opening of the suction air passage 21 'is unlikely to occur. Further, even if a partial dew condensation phenomenon occurs due to load conditions, the amount of dew condensation that can be sufficiently sublimated can be suppressed by the amount of air flowing through the compartment suction air passage 21 '. Although the present embodiment has described the mode in which the compartment suction air passage is provided in the refrigerating compartment suction air passage, the same effect can be obtained by providing the compartment suction air passage in the freezing compartment suction air passage.

る。EFFECTS OF THE INVENTION As is apparent from the above-described configuration, the present invention has an upper freezing compartment divided into upper and lower parts, a lower refrigerating compartment, a cooler arranged behind the freezing compartment, and an upper part of the refrigerating compartment. At the partition wall with the wall of the partition wall as a ceiling wall, a freezing room suction air passage for returning the cold air of the freezing room formed in the partition wall to a cooler, and the refrigerating room formed in the partition wall A refrigerating compartment suction air passage for returning the cool air of the compartment to the cooler, and a compartment suction air passage for returning the cool air of the compartment formed in the compartment wall to the cooler,
The opening of the compartment suction air passage on the leeward side is opened in the middle of the refrigerating compartment suction air passage, and a weir is provided on the windward side of the refrigerating compartment suction air passage, so the blower is stopped. The cold air from the cooler accumulated in the refrigerating chamber suction air passage is not blocked by the weir and flows into the compartment,
The food in the compartment will not be overcooled or frozen.

ものである。Even while the blower is operating, most of the cold air that flows through the compartment suction port side due to the suctioned cold air in the refrigerating room suction air passage flows along the protrusions, causing dew condensation near the communication opening of the compartment suction air passage. The icing is unlikely to occur, and even if dew condensation or icing occurs due to various load conditions, it is possible to suppress the amount of air in the compartment suction air passage to a level that allows sublimation to a sufficient extent. Therefore, there is no fear of ice blocking of the compartment suction air passage, and the practical effect of preventing the cooling function failure in practice is extremely large.
