Abstract

A wirelessly operable cooking appliance for cooking food products includes a wireless communication device. A computing device, such as a smartphone, can wirelessly communicate with the cooking appliance to control and monitor the cooking appliance.

Claims

1. A cooking appliance comprising:

a housing;

an electric heating element disposed within the housing;

a cooking plate mounted on the housing for cooking a food item thereon and configured to be heated by the electric heating element;

a temperature sensor coupled to the cooking plate and configured to monitor a temperature of the cooking plate;

a temperature probe assembly including a temperature probe element, the temperature probe element configured to be inserted into the food item to measure an internal temperature of the food item; and

a control device configured to communicate with a user computing device via a wireless network, receive a cooking configuration from the user computing device via the wireless network, the cooking configuration including at least a target cooking plate temperature setting and a target probe temperature setting, and control the heating element based upon the cooking configuration to heat the cooking plate to the target cooking plate temperature setting such that the internal temperature of the food item reaches the target probe temperature setting.

2. The cooking appliance of claim 1, wherein:

the housing has a forward end and a rearward end; and

the cooking plate has a food contact surface configured to receive a food item, the food contact surface configured to slope down from the rearward end to the forward end when the cooking plate is mounted on the housing.

3. The cooking appliance of claim 1, wherein:

the housing has a forward end and a rearward end; and

the cooking plate has a food contact surface configured to receive a food item, the food contact surface configured to be substantially flat from the rearward end to the forward end when the cooking plate is mounted on the housing.

4. The cooking appliance of claim 1, wherein the cooking configuration includes a target cooking temperature.

16. The cooking appliance of claim 1, wherein the cooking plate is selected from a group consisting of a grill plate, a waffle plate, a bake plate, a muffin plate, a griddle plate, an omelet plate, a meatball plate, a steam plate, a wok plate, and a multi-cooker plate.

5. A method of controlling a cooking appliance, the cooking appliance including an electric heating element and a cooking plate, the cooking plate being arranged and configured to be heated by the electric heating element and being configured for cooking a food item thereon, the method comprising:

receiving cooking configuration data from a user computing device via a wireless network, the cooking configuration data including at least a target cooking plate temperature setting and a target probe temperature setting;

monitoring a temperature of the cooking plate using a temperature sensor coupled to the cooking plate;

monitoring an internal temperature of the food item while the food item is on the cooking plate using a temperature probe assembly, the temperature probe assembly having a temperature probe element inserted into the food item; and

controlling the heating element based on the cooking configuration data to heat the cooking plate to the target cooking plate temperature setting such that the internal temperature of the food item reaches the target probe temperature setting.

6. The method of claim 5, wherein the user computing device is configured to prompt a user to provide a cooking configuration input therethrough and generate the cooking configuration data based upon the cooking configuration input.

7. The method of claim 5, further comprising:

prior to controlling a heating element, controlling the heating element to heat the cooking plate until a temperature of the cooking plate reaches the target cooking temperature; and

prompting a user to place the food item in the cooking appliance.

8. The method of claim 5, further comprising:

prior to receiving cooking configuration data, establishing a wireless connection to the user computing device via a router.

9. The method of claim 8, wherein the user computing device is configured to prompt a user to input a wireless connection password for establishing the wireless connection via the router.

10. A cooking appliance comprising:

a first assembly comprising;

a first housing;

a first electric heating element disposed with the first housing;

a first cooking plate detachably mounted on the first housing, the first cooking plate for cooking a food item thereon and configured to be heated by the electric heating element; and

a first temperature sensor coupled to the first cooking plate and configured to monitor a temperature of the first cooking plate;

a second assembly comprising;

a second housing pivotally coupled to the first housing; and

a second heating element disposed with the second housing;

a temperature probe assembly including a temperature probe element, the temperature probe element configured to be inserted into the food item to measure an internal temperature of the food item;

a control circuit configured to communicate with a user computing device via a wireless network and operable to;

receive cooking configuration data from the user computing device, the cooking configuration data including at least a target cooking plate temperature setting and a target probe temperature setting; and

control at least one of the first and second heating elements based on the cooking configuration data to heat the first cooking plate to reach the target cooking plate temperature until the internal temperature of the food item reaches the target probe temperature setting.

11. The cooking appliance of claim 10, wherein the control circuit is further operable to:

prior to controlling a heating element, control at least one of the first and second heating element to heat the first cooking plate until a temperature of the first cooking plate reaches the target cooking temperature; and

prompt a user to place the food item in the cooking appliance.

12. The cooking appliance of claim 10, wherein the second assembly further comprises a second cooking plate detachably mounted on the second housing.

13. The cooking appliance of claim 10, wherein:

the first housing has a forward end and a rearward end; and

the first cooking plate has a food contact surface configured to receive the food item, the food contact surface configured to slope down from the rearward end to the forward end when the first cooking plate is mounted on the first housing.

14. The cooking appliance of claim 10, wherein the temperature probe assembly further comprises:

a probe body configured to mount the temperature probe element, the probe body including a cord management portion around which a cord is at least partially wrapped.

15. The cooking appliance of claim 10, further comprising:

a probe storage configured to receive and store the temperature probe assembly.
