Technical Field
The invention relates to a temperature control device of a gas stove, in particular to an anti-dry heating probe for the gas stove.
Background
An anti-dry heating probe of a gas stove generally comprises a probe head shell, a temperature sensing controller, a spring and a fixed rod. A temperature sensing controller is arranged in the shell of the probe head, and a spring for controlling the head of the probe to lift is arranged below the temperature sensing controller. When in use, the head of the probe moves up and down relative to the fixed rod. The temperature induction controller adopts a thermistor for temperature control, a kick type temperature controller for temperature control and an NTC (negative temperature coefficient) heat-sensitive sensor for temperature control. In the existing anti-dry heating probe, a section of spring is generally arranged in the head of the probe, and the spring is also completely arranged in the head of the probe. When in use, the service life of the spring is adversely affected due to the higher temperature of the probe head.
In order to effectively contact the top of the dry-heating-preventing probe with the bottom of the pot and better detect the temperature of the bottom of the pot, the dry-heating-preventing probe adopting the thermistor temperature control is adopted in the market, a larger gap is reserved between the head of the dry-heating-preventing probe and a fixed rod along the radial direction at the matching part, so that when the bottom of the pot is locally uneven or inclined, the top of the dry-heating-preventing probe can be automatically adjusted correspondingly and is effectively contacted with the bottom of the pot. The head of the probe can be obviously felt to shake along the radial direction by hands, and the gas stove with the dry-burning-proof probe is easy to damage the dry-burning-proof probe if Chinese style cooking 'tossing pan' is adopted for cooking. The dry-burning prevention probe with the thermistor for temperature control is limited by the working temperature of the thermistor, and generally has the functions of dry burning prevention and excessive temperature burning prevention of edible oil within the use temperature range of 300-360 ℃, so that the dry-burning prevention probe is difficult to adapt to the requirement of high-temperature cooking.
chinese patent document ZL201721619375.1 discloses an anti-dry heating temperature control device for a gas stove, which adopts a bimetallic strip to control temperature, and has an anti-dry heating function and an anti-overheating spontaneous combustion function of edible oil even in the use temperature range of 300-360 ℃ under the condition of 'quick-frying', but also has several disadvantages: firstly, a spring is arranged in a high-temperature area; secondly, the radial clearance of the matched part between the probe head and the fixed rod is small, and the probe does not shake obviously, so that when the pot bottom is locally uneven or inclined, the top of the probe cannot be automatically adjusted along the radial direction, and the contact between the top of the probe and the pot bottom is influenced; third, the holding ring is installed to its dead lever upper end of preventing among the dry combustion method probe base subassembly, between holding ring and the dead lever, leans on the lug at bending dead lever top to link as an organic whole, and this kind of connection structure, junction rigidity itself is relatively poor, during the use, probably leads to the lug to warp because of the atress is big, causes the holding ring bite or pine take off to make and prevent the dry combustion method probe inefficacy.
