Abstract

A refrigerator includes a fermentation compartment having a heater and a cooler. A food container is inserted into the compartment for fermenting food. The container includes a power source, a detector, and a radio transmitter. The detector detects fermentation conditions within the container. That detected information transmitted by the transmitter as radio signals which are received by a controller of the refrigerator which controls the temperature in the fermentation compartment in accordance with the received information. If the power source in the container becomes insufficiently charged, an indicator lamp on the refrigerator is energized.

Claims

1. A refrigerator, comprising:

a case forming at least a fermentation compartment;

a temperature regulating mechanism for regulating the temperature in the fermentation compartment;

a storage container insertable into the fermentation compartment for storing fermenting food, the storage container including a detector for detecting fermentation conditions of fermenting food in the storage container, and a transmitter connected to the detector for transmitting a wireless signal representative of the detected fermentation conditions; and

a refrigerator controller mounted in the case for receiving and processing the signal, the refrigerator controller connected to the temperature regulating mechanism for regulating the temperature in the fermentation compartment in accordance with the signal received from the transmitter.

2. A refrigerator according to claim 1, wherein the refrigerator controller includes a receiver for receiving the wireless signal and being disposed in the fermentation compartment.

3. A refrigerator according to claim 1, wherein the detector includes at least one of:

a temperature sensor, a hydrogen ion concentration sensor, a CO₂ concentration sensor, and a gas pressure sensor.

4. A refrigerator according to claim 1, wherein the transmitter comprises a radio transmitter.

5. A refrigerator according to claim 1, wherein the case forms an additional compartment, the fermentation and additional compartments including a respective, independently controlled heat exchange means for regulation of the temperatures therein.

6. A storage container adapted for use in a refrigerator having at least a fermentation compartment, a temperature regulating mechanism for controlling the temperature within the fermentation compartment, and a signal receiver for receiving wireless signals and being connected to the temperature regulating mechanism, the storage container comprising:

a detector for detecting a fermentation condition of fermenting food in the container; and

a transmitter connected to the detector for transmitting a wireless signal representative of the detected fermentation conditions to the signal receiver.

7. A storage container according to claim 6, wherein the storage container includes a storage container controller connected to the transmitter for transmitting a signal only when there is a detected change in fermentation conditions.

8. A storage container according to claim 7 further including a lid in which the transmitter and storage container controller are disposed.

9. A storage container according to claim 8, wherein the lid further includes a detecting compartment wherein the detector is disposed.

10. A storage container according to claim 6, wherein the detector includes at least one of:

a temperature sensor, a hydrogen ion concentration sensor, a CO₂ concentration sensor, and a gas pressure sensor.

11. A storage container according to claim 9, wherein the detecting compartment includes a wall having pores through which gases from the fermenting food passes.

12. A storage container according to claim 11, wherein the detector includes a hydrogen ion concentration detector disposed outside of the detecting compartment and connected to a wire which projects through a pore in the detecting compartment.

13. A storage container according to claim 6, wherein the transmitter constitutes a radio signal transmitter.

14. A refrigerator, comprising:

a case forming at least a fermentation compartment adapted to receive a storage container which contains fermenting food and a transmitter for sending a wireless signal representative of fermentation conditions in the container;

a temperature regulating mechanism for controlling the temperature in the fermentation compartment; and

a refrigerator controller connected to the temperature regulating mechanism and including a signal receiver for receiving a wireless signal from the transmitter to regulate the temperature in the fermentation compartment in accordance with the signal.

15. A refrigerator according to claim 14, wherein the receiver is a radio receiver for receiving a radio signal.

16. A refrigerator according to claim 14, wherein the case forms an additional compartment, the fermentation and additional compartments including a respective, independently controlled heat exchange means for regulation of the temperatures therein.

17. A method of controlling the fermentation of food in a refrigerator, comprising the steps of:

A) providing the refrigerator with at least a fermentation compartment;

B) placing in the fermentation compartment a storage container containing food to be fermented, the storage container including a detector for detecting the fermentation condition of the food, and a transmitter;

C) actuating the detector for detecting the fermentation condition of the food;

D) actuating the transmitter for transmitting a wireless signal representative of the detected fermentation condition; and

E) causing a temperature regulating mechanism in the refrigerator to receive the wireless signal and control the temperature of the fermentation compartment in accordance with the wireless signal.

18. A method according to claim 17, wherein step D comprises transmitting a radio signal.

19. A method of controlling a refrigerator which includes at least a fermentation compartment, comprising the steps of:

A) detecting the fermentation condition of fermenting food disposed within a storage container placed within the fermentation compartment and comparing the detected condition with a reference condition;

B) controlling the temperature in the fermentation compartment in accordance with the result of the comparison in step A;

C) sensing a condition wherein a power supply in the storage compartment is insufficiently charged; and

D) actuating an indicator indicating the condition sensed in step C.

20. A method according to claim 19, wherein step A comprises sensing at least one of:

temperature, hydrogen ion concentration, CO₂ concentration, and gas pressure in the storage container.
