Problems solved by technology

[0003] However, the placement of the wires in the hood, the mounting of the handle on the hood and the connection of the wires to the control are operations that are difficult to achieve during the automated production of cooking vessels
[0004] Furthermore, during installation or abnormal use, especially when the cooking vessel is overheated, the wires can be damaged and lead to incorrect temperature measurements

Embodiment Construction

[0056] Such as figure 1 and figure 2 As shown, the cooking vessel 1 comprises a hood 2 comprising a bottom 3 and side walls 4 . The cover 2 is made of a non-magnetic material, in particular aluminum, for example by a stamping operation of the disc or by a casting operation. The bottom 3 has a thickness in which the magnets 10 are embedded, preferably by a punching operation. The magnet 10 has remanence, and the remanence changes according to the temperature of the cover 2 to generate a change in the magnetic field. The cooking vessel 1 comprises a handle 20, the end 21 of which is fixed to the side wall 4 by a fixing mechanism (not shown in the figure). The handle 20 includes a magnetic field measuring sensor 22 connected to a control device 25 . The magnetic field measuring sensor 22 is positioned as close as possible to the housing 2 . The magnetic field measurement sensor measures changes in the magnetic field from the magnet 10 and generates a change in an electrical...

Abstract

The present invention relates to a cooking receptacle (1). The cooking receptacle (1) is disposed on a heating board (30), a combustion furnace or an analogue for cooking foods. The cooking receptacle comprises one or more than one cover (2) made of nonmagnetic materials. According to the invention, the cover (2) includes a magnet (10) which has nonzero remanence changing with the temperature and the Curie temperature of larger than 350 DEG C, the changing of the remanence generates the changing of the magnetic field, and the magnet (10) is used for cooperating with at least one magnetic field measurement sensors (22, 22a) arranged around the cover (2). The electrical signals used in a control device (25) generated by the magnetic field measurement sensor to permit the determination of the cover temperature.

Description

technical field [0001] The invention relates to a cooking vessel comprising a sensor, more particularly a temperature sensor. The cooking vessel is intended to be placed on a cooking plate, burner or similar for food cooking. The cooking vessel is in particular a saucepan, a saucepan, a frying pan, an amphorae or a pressure cooker. Background technique [0002] From document EP0931495 is known a cooking vessel comprising a bottom and a temperature sensor integrated between the bottom and a perforated plate mounted on the bottom. The temperature sensor is connected via two wires to a control device provided in the handle to process the measured values ​​and determine the temperature. The temperature sensor and the two wires are arranged in a receiving duct realized in the bottom of the cooking vessel. [0003] However, the placement of the wires in the hood, the mounting of the handle on the hood and the connection of the wires to the control device are operations that are...
