Abstract

Disclosed herein is a cooking apparatus including a heating unit configured to heat an ingredient contained in a cooking chamber, a gas sensor configured to detect a gas inside the cooking chamber, a communication unit configured to communicate with an external apparatus, and a control unit configured to determine a cooking progress state of the ingredient based on the type and concentration of the gas detected by the gas sensor and to transmit information on the cooking progress state to the external apparatus through the communication unit to inform a user of the cooking progress state.

Claims

1. A cooking apparatus comprising:

a heater configured to heat an ingredient in a cooking chamber of the cooking apparatus;

a gas sensor configured to detect a gas generated by the ingredient inside the cooking chamber;

a communication device configured to communicate with an external apparatus; and

a controller configured to;

determine at least one of a type of the gas and a concentration of the gas detected by the gas sensor based on a change in a resonant frequency of a component of the gas sensor,

determine a cooking progress state of an ingredient in the cooking chamber of the cooking apparatus based on the determined at least one of the type of the gas and the concentration of the gas detected by the gas sensor, and

transmit information on the determined cooking progress state to the external apparatus through the communication device to inform a user of the cooking progress state of the ingredient.

2. The cooking apparatus of claim 1, wherein the controller determines at least one of the cooking progress state of the ingredient and a type of the ingredient based on the determined at least one of the type of the gas and the concentration of the gas detected by the gas sensor.

3. The cooking apparatus of claim 2, wherein the controller determines at least one of a cooking mode, a cooking time, and a cooking temperature according to the determined type of the ingredient.

4. The cooking apparatus of claim 2, wherein the controller transmits information to the external apparatus through the communication device about a food item for a next meal according to the determined type of the ingredient to inform the user of the food item for the next meal.

5. The cooking apparatus of claim 2, wherein the controller transmits information to the external apparatus through the communication device about an additional food item according to the determined type of the ingredient to inform the user of the additional food item.

6. The cooking apparatus of claim 2, wherein the controller transmits ingredient information including the determined type of the ingredient to an external dishwasher to allow the external dishwasher to control a washing program based on the determined type of the ingredient.

7. The cooking apparatus of claim 1, wherein the controller determines whether cooking of the ingredient is completed based on the type of the gas and the concentration of the gas detected by the gas sensor and transmits a cooking completion display request to the external apparatus through the communication device to inform the user that the cooking is completed.

8. The cooking apparatus of claim 1, wherein the controller determines a cooking completion time of the ingredient based on at least one of the type of the gas and the concentration of the gas detected by the gas sensor and transmits information on the cooking completion time to the external apparatus through the communication device to inform the user of the cooking completion time.

9. The cooking apparatus of claim 1, wherein the controller transmits a ventilation request message to an external air conditioner through the communication device when the concentration of the gas detected by the gas sensor is higher than a reference value.

10. A gas detection apparatus comprising:

a gas sensor configured to detect a gas inside a cooking chamber of a cooking apparatus;

a communication device configured to communicate with an external apparatus; and

a controller configured to;

determine at least one of a type of the gas and a concentration of the gas detected by the gas sensor based on a change in a resonant frequency of a component of the gas sensor,

determine a cooking progress state of an ingredient in the cooking chamber of the cooking apparatus based on the determined at least one of the type of the gas and the concentration of the gas detected by the gas sensor, and

transmit information on the determined cooking progress state to the external apparatus through the communication device to inform a user of the cooking progress state.

11. The gas detection apparatus of claim 10, wherein the controller determines a type of the ingredient based on the determined type and the determined concentration of the gas detected by the gas sensor.

12. The gas detection apparatus of claim 11, wherein the controller determines at least one of a cooking mode, a cooking time, and a cooking temperature according to the determined type of the ingredient.
