It is configured to be kept at a higher humidity than the above), and because the temperature and humidity conditions are easily adjusted optimally, the effect of maintaining the freshness of fruits and vegetables is high, the inflow of cold air into the vegetable compartment 12, the vegetable compartment 12 Since it has a cooling means (cooling plate 12a) dedicated to the vegetable compartment 12 that does not require the outflow of cold air from the
The fluctuation of the specific gas (ethanol gas) concentration in the vegetable compartment 12 is small, and the detection accuracy of the specific gas (ethanol gas) concentration can be improved.

In addition, in the refrigerator of this embodiment, the atmosphere sensor (atmosphere sensor unit 24) is used in the vegetable compartment 1.
It is arranged behind the storage container 15 that is pulled out together with the pull-out door 14 of No. 2 below the back surface of the vegetable compartment 12, and is less affected by temperature changes due to opening and closing of the pull-out door 14 of the vegetable compartment 12, Therefore, the fluctuation of the output value of the atmosphere sensor (atmosphere sensor unit 24) due to the temperature change is small, and it is difficult for dew condensation to occur. Further, the fluctuation of the surrounding specific gas (ethanol gas) concentration due to the opening and closing of the doors 13 and 14 is relatively small, so that the detection accuracy of the specific gas (ethanol gas) concentration can be improved.

Further, the specific gas to be detected is a sulfur-based or alcohol-based gas, and when the concentration of the sulfur-based or alcohol-based gas is equal to or higher than a predetermined concentration, enlightenment is made to remove the cause of generation of these gases. This allows the user to eliminate the cause of generation of these gases and maintain the freshness of fruits and vegetables.

The specific gas to be detected includes a gas that deteriorates fruits and vegetables and a gas that is generated from the fruits and vegetables itself, and the concentration of the gas that deteriorates the fruits and vegetables or the gas generated from the fruits and vegetables itself is equal to or higher than a predetermined concentration. In some cases,
By enlightening people to remove the causes of these gases, it is possible to ask the user to remove the causes of these gases and maintain the freshness of fruits and vegetables.

Further, in the refrigerator of the present embodiment, since the specific gas to be detected is ethanol gas, it has an effect of further improving the freshness control effect on fruits and vegetables and fat-based foods.

In protein foods such as beef, when the ethanol gas concentration is high, the molecular structure of the protein is deformed (whitened).

Fat-based foods such as butter, margarine, and cheese are exposed to ethanol gas,
The fat on the food surface is defatted, the food surface becomes uneven, the surface area increases, and the oxidation (yellowing) of the fat increases.

As for fruits and vegetables, ethanol gas acts on the metabolic system of vegetables to cause discoloration.

Incidentally, spinach, sunny lettuce, Chinese cabbage,
Vegetables such as lettuce generate a relatively large amount of ethylene gas when spoiled, so if the amount of vegetables is large, it is possible to detect spoilage with an atmosphere sensor. Difficult to detect. In addition, the amount of gas generated during spoilage varies greatly depending on the type of vegetable, and vegetables (onion, shiitake mushroom, shimeji mushroom, enoki, leek) that cannot detect spoilage with an atmosphere sensor that generate ethanol gas even before deterioration progresses. ) And the amount of ethanol gas generated during decay is too small to detect the decay by the atmosphere sensor (Komatsuna, bok choy, cucumber).

Further, since the amount of ethanol gas generated from miso, takuwan, and shimeji was overwhelmingly larger than the amount of ethanol gas generated from rotten vegetables, the ethanol gas detection level of the atmosphere sensor was set to miso, takuwan, When used with shimeji and other foods that produce ethanol, it becomes difficult for the atmosphere sensor to detect rotten vegetables.

Further, the amount of ethanol gas generated from miso, takuwan, and shimeji is overwhelmingly larger than the amount of ethanol gas generated from rotten vegetables. It is important to prevent the leakage of ethanol gas from foods that generate ethanol, such as Takuwan, Takuwan and Shimeji.

Regarding ethylene gas which is generated from fruits and vegetables and affects the preservation of fruits and vegetables, it is preferable to place an antibacterial agent that emits wasabi and mint components, which has an ethylene gas generation suppressing effect, in the vegetable compartment 12. .
