Problems solved by technology

[0004] However, in the conventional freezer described in the Publication No. 3-83793, in order to carry out effective deodorization, it is necessary to close the baffle of the main circulation air path. However, once the baffle is closed, the air resistance will decrease. If it becomes overwhelmingly large, the cold air will pass through the bypass air passage equipped with a deodorizing device, so the cold air will hardly enter the main circulation air passage, and the cooling of each chamber in the freezer will obviously be insufficient.
[0005] In addition, when the deodorization operation is performed while the compressor is stopped, there is also a problem that the temperature of each compartment of the freezer rises, so there is a problem that the improvement of the deodorization ability and the assurance of the cooling ability cannot be achieved at the same time.
Moreover, although the odor is used in the deodorization device and the odor is decomposed by the deodorization catalyst, the decomposition efficiency of the deodorization

Abstract

An odorless refrigerator with a deodorizing function free from insufficient refrigeration, which is provided with a deodorizing device operable with a stable deodorizing performance for a long time, simply structured, small-sized, and provided at a low cost. The refrigerator includes a draft air duct as a passage of refrigerated air blown off forcibly by an inside fan to the compartments, a damper in the draft air duct and opens/closes to allow/prevent the supply of refrigerated air to the compartments, a bypass channel in the draft air duct between the damper and a cooling device for returning refrigerated air from the cooling device to the cooling device, and a deodorizing device in the by-pass channel for deodorizing refrigerated air supplied to the compartments. The refrigerated air inside the draft air duct between the damper and the cooling device is forcibly blown off through the bypass channel by closing the damper.

Description

technical field [0001] The present invention relates to a refrigerator equipped with a deodorizing device. Background technique [0002] As an example of the known technology, there is a freezer with a deodorizing device described in Utility Application Publication No. 3-83793. The above-mentioned refrigerated refrigerator is provided with a bypass (by-pass) air path with a deodorizing device inside a part or all of the circulating air path in the refrigerator, and it is characterized in that: the air resistance is smaller than the above-mentioned bypass air path The circulation air path of the main circulation air path and the bypass air path in the refrigerator is in a shunt state. As for the deodorizing device, a combination of an odor generating device and a deodorizing catalyst is used. A baffle is provided in the main circulation air path, and the deodorizing effect is improved by closing the above-mentioned baffle. On the contrary, since the cold air can flow into ...
