Temperature-sensing synchronous roasting machine

Abstract

The invention relates to a temperature-sensing synchronous roasting machine, which comprises an electrical heated tube for heating a bakeware and food on the front of the bakeware, a temperature controller for measuring the temperature of the bakeware, and a fuse for electrical safety protection, wherein the electrical heated tube, the temperature controller and the fuse are all arranged on the bakeware; the distance L between the temperature-sensing points of the temperature controller and the fuse on the bakeware is not more than 35mm; the bakeware is provided with a pit; and the fuse is arranged in the pit of the bakeware. In the invention, the distance between the temperature controller and the fuse is very small, thus improving the temperature-sensing synchronism; the temperature of the fuse at normal operation condition changes with that of the temperature controller, and is not influenced or little influenced by external factors, thus ensuring that the fuse has stable and controllable work temperature and guaranteed service life and does not conduct protection prematurely or abnormally advance protection; and when the temperature controller is in normally through condition due to damage, the fuse senses the continued rising of the temperature at the first time and conducts safety protection, thus ensuring personnel safety and having high safety factor.

Description

technical field [0001] The invention relates to a frying and roasting machine, in particular to a frying and roasting machine with synchronous and accurate temperature sensing of a temperature controller and a fuse, which belongs to the modification technology of the frying and roasting machine. Background technique [0002] Existing commercially available grill, its thermostat and fuse usually adopt such as Figure 7 The fixing method shown is: the electric heating tube 2 is installed in the groove on the back of the baking pan 1, the thermostat 3 is fixed on the baking pan 1 close to the hot end of the electric heating tube, and the fuse 4 is fixed on the baking pan 1 close to the electric heating tube the cold end. For frying machines with this structure, the distance L between the temperature controller 3 and the fuse 4 is relatively large. For a baking pan with a diameter of 300mm, generally L is about 90mm, and the temperature perception of the corresponding temperatur...

Problems solved by technology

For frying machines with this structure, the distance L between the temperature controller 3 and the fuse 4 is relatively large. For a baking pan with a diameter of 300mm, generally L is about 90mm, and the temperature perception of the corresponding temperature controller and fuse will also affect the temperature of the baking pan. There is obvious asynchrony, especially when the cooling food to be heated is placed on the grill pan 1 where the thermostat 3 is fixed, the temperature of the grill pan sensed by the thermostat is low, and the electric heating tube of the frying machine is continuously energized to heat, so that the entire grill The temperature of the pan keeps rising, especially the temperature of the baking pan where the fuse is fixed is extremely high, so that the temperature of the fuse is very unstable, which affects the service life, and when the temperature of the baking pan is high, it is easy to cause the fuse to blow for safety protection
