Cookware with rf detection function and cookware system

Abstract

A cookware includes a cookware body, and the cookware body includes an RF device and a time module thereon. The time module monitors a cooking time of the cookware and sends a cooking time signal to the RF device; and the RF device sends a time alarming signal for alerting a user to an external receiver once the cooking time reaches a pre-set time. Once the cooking time reaches a pre-set time or the cooking temperature reaches a pre-set over boiling temperature, corresponding alarming signals are sent by the RF device to the receiver so that the user can take corresponding actions to prevent occurrence of an accident, thus improving the safety of the cookware. Furthermore, the cookware can periodically monitor the cooking time and the cooking temperature automatically to allow the user to keep track of the cooking time and the cooking temperature in real time, which is convenient.

1 . A cookware with a radio frequency (RF) detection function, comprising a cookware body, the cookware body being provided with an RF device and a time module thereon, wherein:
 the time module is configured to monitor a cooking time and send a cooking time signal to the RF device; and   the RF device is configured to send to an external receiver a time alarming signal for alerting a user once the cooking time reaches a pre-set time.   
     
     
         2 . The cookware of  claim 1 , wherein the cookware body is further provided with a temperature module for monitoring a cooking temperature and sending a cooking temperature signal to the RF device; and
 the RF device is further configured to send to the receiver a temperature alarming signal for alerting the user once the cooking temperature reaches a predetermined over boiling temperature.   
     
     
         3 . The cookware of  claim 1 , wherein the RF device is further configured to send time alerting signals for alerting the user to the receiver at time intervals of a first preset time period before the cooking time reaches the pre-set time. 
     
     
         4 . The cookware of  claim 2 , wherein the RF device is further configured to send temperature alerting signals for alerting the user to the receiver at time intervals of a second preset time period before the cooking temperature reaches the predetermined over boiling temperature. 
     
     
         5 . The cookware of  claim 2 , wherein the cookware body comprises a body having a cookware handle, and the time module, the temperature module and the RF device are all disposed on the cookware handle. 
     
     
         6 . The cookware of  claim 2 , wherein the cookware body includes a lid having a lid handle, and the time module, the temperature module and the RF device are all disposed on the lid handle of the lid. 
     
     
         7 . The cookware of  claim 2 , wherein the time module is at least a timer or a time sensor, and the temperature module is at least a thermometer or a temperature sensor. 
     
     
         8 . The cookware of  claim 7 , wherein the time alarming signal and the temperature alarming signal are each at least an audio signal, a flashing light signal or a vibration signal. 
     
     
         9 . The cookware of  claim 6 , wherein the receiver is a remote controller having an interface for displaying the temperature and the time. 
     
     
         10 . A cookware system with an RF detection function, comprising a cookware and a receiver in communication with the cookware through an RF signal, wherein: the cookware is as claimed in  claim 1 ; and
 the receiver is configured to receive an alerting signal sent by the RF device and alert the user by means of the interface, the audio signal, the flashing light signal or the vibration signal.   
     
     
         11 . The cookware of  claim 3 , wherein the time module is at least a timer or a time sensor, and the temperature module is at least a thermometer or a temperature sensor. 
     
     
         12 . The cookware of  claim 4 , wherein the time module is at least a timer or a time sensor, and the temperature module is at least a thermometer or a temperature sensor. 
     
     
         13 . The cookware of  claim 5 , wherein the time module is at least a timer or a time sensor, and the temperature module is at least a thermometer or a temperature sensor. 
     
     
         14 . The cookware of  claim 6 , wherein the time module is at least a timer or a time sensor, and the temperature module is at least a thermometer or a temperature sensor.
