There is a freezer-refrigerator with a deodorizing device introduced in Japanese Patent No. 793. This freezer-refrigerator is provided with a bypass air passage in which a deodorizing device is installed in part or all of the circulation air passage in the refrigerator,
It is characterized in that the circulation air passage in the refrigerator is branched into a main circulation air passage and a bypass air passage having less air resistance than the bypass air passage. As the deodorizing device, a combination of an ozone generator and a deodorizing catalyst is used. A damper is provided in the main circulation air passage, and the deodorizing effect is improved by closing the damper. On the other hand, by opening the damper, the cool air is made to flow into the main circulation air passage to cool it, so most of the cool air will flow into the main circulation air passage, eliminating the problem of insufficient cooling. Is to do.

ては、脱臭機能は重要な機能の１つである。The odor generated from food not only causes discomfort when the door of the freezer / refrigerator is opened, but also the odor is transferred to other foods. This is one of the important functions.

しく冷却不足になるという問題があった。However, in the conventional refrigerator-freezer disclosed in Japanese Utility Model Publication No. 3-83793, the damper in the main circulation air passage must be closed for effective deodorization, but the damper is closed. If this happens, the cool air must pass through the bypass air passage where the deodorizing device with overwhelmingly large air resistance is installed, so the cool air hardly goes to the main circulation air passage, and each room in the refrigerator / freezer is significantly There was a problem of insufficient cooling.

影響を与えたりするという問題があった。Further, when the deodorizing operation is carried out while the compressor is stopped, there is a problem that the temperature of each room of the freezer-refrigerator rises, and it is impossible to improve both the deodorizing capacity and the cooling capacity at the same time. There was a problem. In addition, although ozone is used in the deodorizing device to decompose this ozone by the deodorizing catalyst, the decomposition efficiency of the deodorizing catalyst decreases due to long-term use, and ozone flows back into the refrigerating room and adversely affects food and the like. There was a problem of giving it.

形にしなければならないという問題があった。Further, in the structure of the conventional refrigerator-freezer, it is impossible to deodorize all the rooms of the refrigerator-freezer unless the deodorizing device is arranged in the circulation air passage for guiding the cool air to the rooms of the refrigerator-freezer. If the deodorizing device is placed in the circulation air passage that guides cool air to all the rooms of the refrigerator / freezer, the air passage becomes complicated and the cost is increased. In particular, if the bypass air duct is branched from the main circulation air duct in order to provide a bypass air duct for all circulation air ducts, the number of branch air ducts will increase by the amount of the bypass air duct, and more space will be required for the refrigeration room. There is a problem that the capacity of a room such as a refrigerator or a freezer must be reduced, or the size of a refrigerator must be increased.

冷蔵庫の脱臭運転が終了する。Then, in S5, it is determined whether or not the internal fan 14 has been operated for a predetermined time. If it is determined that the fan 14 has not been operated for the predetermined time, the process returns to S5 and the time is continuously counted. If it is determined in S5 that the internal fan 14 has operated for a predetermined time, the internal fan operation is terminated in S6, and the time counted by the timer is reset. In the case of the present embodiment, the predetermined time is a time required for all the air in the cooler chamber in which the cooler 13 is arranged to pass through the deodorizing device 22, and is about several seconds to several minutes. For example, when the air volume around the cooler 13 is 0.05 cubic meters, the operating time of the internal fan 14 is about 30 seconds. S
When the operation of the internal fan is completed in 6, the deodorizing operation of the refrigerator is completed in S7.

You can get a clean refrigerator with no odor. Furthermore, if the deodorizing operation is performed after the defrosting operation is finished, the foul odor associated with the temperature rise of the cooler room immediately after the defrosting does not flow into each room of the refrigerator, so that a refrigerator having no bad odor can be obtained. In addition, the compressor 11
Since cold air is prevented from passing through the deodorizing device 22 during the operation of, the deterioration of the cooling performance can be prevented.

る。Also, most of the cool air in the cool air supply air passage in the refrigerator body 1 passes through the cooler 13 with odor, but since the cooler 13 is frosted, it is between the cooling fins of the frosted cooler 13. The odor is easily trapped. This trapped odor melts the frost that has formed due to the temperature rise due to the defrosting operation, etc., and becomes an offensive odor and is released into the cooler chamber. Therefore, in the present embodiment, the internal fan 14
The bypass flow passage 21 having the deodorizing device 22 is configured so that a short cycle occurs in which the cool air blown by passes through the bypass flow passage 21 and returns to the cooler chamber in which the cooler 13 is arranged. Thus, it is possible to efficiently deodorize the cooler room where the offensive odors generated in each room of the refrigerator are likely to be collected and accumulated, and it is possible to provide a refrigerator with a clean sensation without any offensive odor. Further, if the bypass flow passage 21 is provided independently of the air flow passage, the bypass flow passage does not affect the air blowing performance of the air flow passage such as the size and length of the air flow passage. Larger and cheaper refrigerators can be obtained.
