The display means 34 is composed of a liquid crystal panel or the like and is attached to the surface of the door 13 of the refrigerator compartment.

Regarding the refrigerator configured as described above,
The operation will be described below with reference to FIG.

First, when fresh vegetables are stored in the vegetable compartment 12, the inside of the vegetable compartment 12 is caused by gas generated from the stored items such as vegetables and fruits stored in the vegetable storage container 15 of the vegetable compartment 12. Reducing gases such as alcohols and aldehydes are present in low concentrations.

When the compressor 16 is turned on / off, outside air is introduced by opening / closing the doors 14 and 13 of the vegetable compartment and the refrigerator compartment, and the temperature change due to defrosting of the first cooler 17, the sensor cover is vented. The output voltage of the atmosphere sensor 24 that detects gas through the portion 31c repeats a waveform having a peak when the temperature rises, and changes at a level according to the concentration of the reducing gas at that time.

However, the outside air invades into the vegetable compartment 12 when the door 14 is opened or closed, and the ambient temperature of the atmosphere sensor 24 temporarily rises to increase the voltage value, and the vegetables are damaged even when fresh vegetables are stored. I will judge. For this reason, the vegetable temperature sensor 30 is placed in the same substrate 3 near the atmosphere sensor 24.
1a, the ambient temperature is sensed through the ventilation part 31c of the sensor cover, and input to the temperature correction means 33 built in the control means 32 to inform the user of the accurate storage state by the voice notification means 35 or display means. This can be notified by 34 and erroneous detection can be prevented.

Next, for example, when the vegetables in the vegetable compartment 12 are damaged, the reducing ability of ammonia, ethanol, acetaldehyde, dimethyl sulfide, etc., generated from the vegetables in the vegetable compartment 12 when the preservation condition of the vegetables deteriorates. Filled with gas.

Therefore, the sensing layer 2 of the atmosphere sensor 24
The oxygen in the air adsorbed on the surface of the tin oxide forming 8 is reduced by the reducing gas described above, and the atmosphere sensor 24
The electrical resistance is decreased and the output voltage is increased according to the concentration of the reducing gas.

Then, the output voltage after the rise changes in a waveform in which the peak of the temperature rise is repeated in accordance with the above-mentioned various temperature fluctuation factors as in the case of storing fresh vegetables.

Therefore, the magnitude of the output voltage increase width V at the peak a time immediately before the output voltage of the atmosphere sensor 24 when storing fresh vegetables and at the peak b immediately after the output voltage increase is a predetermined output voltage increase determined in advance. If the width is larger than the width, the control means 32 determines that the reducing gas concentration is high and the ambient temperature is also high, so that the environment in which the freshness of the stored items stored in the vegetable compartment 12 is deteriorated is judged. Display information is sent to the display means 34, and the user visually recognizes on the liquid crystal panel that the storage state of the vegetables in the vegetable compartment 12 has deteriorated by, for example, an image drawing or animation.

At the same time, voice information is sent from the control means 32 to the voice notification means 35, and the user can be notified by voice that the preservation state of the vegetables in the vegetable compartment 12 has deteriorated.

As described above, according to the present embodiment, the freshness is detected by detecting the concentrations of the sulfur compound gas and the reducing gas generated from the contents themselves stored in the vegetable compartment 12 as the deterioration of the freshness progresses as in the conventional example. Unlike the one that drives the maintenance device, when the freshness of the vegetables decreases, the atmosphere sensor 24 detects the change in the specific gas concentration generated from the vegetables, and displays the refrigerator in advance before the damage to the vegetables progresses. By using the means 34 or the voice notifying means 35, the user can economically manage the food storage.

Further, as shown in FIG. 1, the sulfur-based gas, which is apt to be generated when the vegetables are damaged, has a larger specific gravity than air, and therefore tends to accumulate on the lower surface of the vegetable compartment. Further, if the sensor assembly 31 is arranged on the rear wall surface 25 of the vegetable compartment 12 in order to reduce temporary temperature fluctuations due to external factors, a temperature rise due to the outside air when the door is opened and closed and a cold air passage are also formed. Since there is no condensation, the temperature correction value can be reduced as much as possible, and the storage state can be accurately detected.

Furthermore, the sensor assembly 31 is attached to the vegetable compartment 1
If it is provided below the vegetable storage container 15 on the rear wall surface of 2, the stable output characteristics can be obtained for a longer period of time, and the state of vegetables can be detected and notified accurately without opening the door.

Further, by providing the atmosphere sensor 24 and the vegetable compartment temperature sensor 30 on the same substrate 31a, the ambient temperature can be accurately detected and the function can be achieved at a low cost.

(Second Embodiment) FIG. 7 is a sectional view of a refrigerator according to a second embodiment of the present invention.

In FIG. 7, reference numeral 36 is a refrigerator body,
A refrigerating compartment 11 is formed in the upper part, and a vegetable compartment 12 for storing vegetables and fruits is formed in the lower part. The refrigerating compartment 11 and the vegetable compartment 12 are partitioned by a partition plate 37, and cold air generated by the first cooler 17 is provided at the rear of the partition plate 37 to supply air to the vegetable compartment 12 3
8 to the exhaust port 39 in front of the partition plate 37.

The sensor assembly 31 is provided in the vegetable compartment 12, and the sulfur-based gas, which is often generated when the vegetables in the vegetable compartment 12 are damaged, and the air supply port 38 to pass ammonia, alcohol, and Aldehyde-based and sulfur-based gases are carried and such composite gas components are detected by the sensor assembly 31.

Normally, even when the gas is not generated as described above, the temperature inside the vegetable compartment 12 temporarily rises due to opening and closing of the door 14, and the atmosphere sensor 24 is affected by the temperature, so that the vegetable preservation state is maintained. The same substrate 31a
Atmosphere sensor 2 with vegetable room temperature sensor 30
The temperature in the vicinity of 4 is detected, and the temperature correction means 33 incorporated in the control means 32 corrects the erroneous detection of the atmosphere sensor 24, so that the user can be notified of the accurate storage state of the vegetable compartment 12.

If the sensor assembly 31 is arranged on the rear wall surface 25 of the vegetable compartment 12, the temperature fluctuation due to the opening and closing of the door is unlikely to occur, so that the fluctuation range of the internal temperature can be made as small as possible. The storage status can be detected. Further, by disposing the sensor assembly 31 on the rear wall surface of the vegetable compartment 12 below the vegetable storage container 15, the state of the vegetables can be detected and notified to the user with high accuracy.
