Description

Technology Field

[0001] The present invention relates to an induction safety timer. Background Technology

[0002] Currently, induction ranges (hereinafter referred to as 'induction') are an innovative tool in modern kitchens, and thanks to their fast and efficient cooking methods, many people are choosing induction ranges instead of traditional gas ranges.

[0003] Induction cooktops utilize technology that generates heat through electromagnetic induction, shortening cooking times and maximizing energy efficiency. They offer various advantages, including the absence of combustion flames, superior safety compared to other electric cookware, ease of cleaning, and precise temperature control. However, because these cooktops can consume high power instantaneously, they are generally powered by an external power supply.

[0004] Induction ranges are sometimes equipped with a timer function for convenient use. Generally, the timer function is designed to be set for each individual burner. However, users tend not to use it often, and there is the inconvenience of having to set the timer for each burner individually if you want to stop the operation of all burners or the induction range itself after a certain period of use.

In this embodiment, the non-contact temperature sensor (140) is provided in the second plug (120). However, depending on the use, the non-contact temperature sensor (140) may be provided in the first plug (110), or it may be provided in both the first plug (110) and the second plug (120) to increase convenience of use.

[0090] Here, since the first plug (110) and the second plug (120) are connected by wireless communication, if they are within the communication range, the first plug (110) and / or the second plug (120) containing a non-contact temperature sensor (140) can be plugged into an outlet (10) located at a position where the temperature of a dish placed on the induction cooker (20) or the surroundings can be detected.

[0091] As a non-contact temperature sensor (140), an infrared temperature sensor (140), an electromagnetic wave temperature sensor (140), etc., may be used.

[0092] Since the non-contact temperature sensor (140) must be positioned near the induction (20) and installed so as to face the top of the induction (20), the position of the induction (20) is adjusted so that the non-contact temperature sensor (140) faces the top of the induction (20), or the first plug (110) or second plug (120) equipped with the non-contact temperature sensor (140) is connected to an outlet (10) near the induction (20), or the position of the first plug (110) or second plug (120) equipped with the non-contact temperature sensor (140) is adjusted using a power strip or the like.

[0093] The signal transmission unit (124) of the second plug (120) receives the temperature detected by the non-contact temperature sensor (140), and when the temperature reaches the set overheating temperature, it transmits a power cutoff signal to the first plug (110) via wireless communication, and the first plug (110) cuts off the power supply from the outlet (10) to the induction (20).

[0095] Hereinafter, an induction safety timer according to the fourth embodiment of the present invention will be described.

[0096] The induction safety timer according to the fourth embodiment of the present invention comprises a first plug (110), a second plug (120), and a terminal (130).

[0097] The first plug (110), second plug (120), and terminal (130) of this embodiment are basically the same as those of the second embodiment.

[0098] However, as in the third embodiment, at least one of the first plug (110) and the second plug (120) further includes a non-contact temperature sensor (140) that detects the temperature of the tableware placed on the induction cooker (20) or the surroundings. The non-contact temperature sensor (140) is the same as in the third embodiment.

[0099] The signal transmission unit (124) of the second plug (120) receives the temperature detected by the non-contact temperature sensor (140), and when the temperature reaches the set overheating temperature, it transmits a power cutoff signal to the first plug (110) via wireless communication, and the first plug (110) cuts off the power supply from the outlet (10) to the induction (20).

[0100] In addition, the signal transmission unit (124) of the second plug (120) receives the temperature detected by the non-contact temperature sensor (140) and, when the temperature reaches the set overheating temperature, notifies the user through an app installed on the user terminal (130).

[0101] After checking the overheating temperature and waiting, the user can instruct the temperature sensor (140) to measure the temperature again, and when the temperature drops, the user can order the induction cooker to operate again. That is, the user can indirectly control the power control unit (113) of the first plug (110) through the second plug (120) to remotely resume power supply from the outlet (10) to the induction cooker (20).
