Description
Technical Field
The invention relates to the technical field of stoves, in particular to a temperature measuring device of a gas stove, the gas stove and a temperature control method of the gas stove.
Background
Investigation data shows that two main causes of household fires are currently: fire caused by short circuit of electric wires and fire caused by fire in kitchen. When a user uses the gas stove, the user forgets the gas stove in a use state occasionally because of other things (such as going out or watching television programs when meeting emergency), so that food in the pot is boiled, carbonized and evaporated to be dry-burned, and serious fire is caused. In view of this, gas stoves having a dry burning prevention function are emerging on the market.
In general, as shown in fig. 1, the main dry burning prevention scheme in the market is as follows: a conductive temperature sensor 4 (NTC thermistor) is provided in the middle of the burner 3 so as to be in direct contact with the bottom of the pot, thereby sensing the temperature inside the pot 1. Although the temperature sensor 4 can sense the temperature of the cooker 1 to a certain extent, the temperature sensor needs to be in direct contact with the bottom of the cooker, so that the contact area is small, the heat conduction speed is low, and misjudgment is easy to cause. In addition, in the long-term use process, carbon deposition is formed on the head of the temperature sensor 4 due to carbonization of food and soup, so that the sensing time is further prolonged, and misjudgment is caused. In addition, when the temperature sensor 4 is used, enough cooling gaps 5 are required to be reserved between the head part and the burner 3, and if the cooling gaps 5 are smaller, the cooling effect of the temperature sensor 4 is greatly weakened, so that erroneous judgment is caused; if the cooling gap 5 is large, the radial dimension of the burner 3 must be increased, which makes it difficult for the gas range to achieve smaller fire power. In addition, when such a gas range is used in a windy state, the flame 2 at the head of the burner 3 swings under the influence of the air flow, and if the flame 2 contacts with the probe of the temperature sensor 4, erroneous judgment of the temperature sensor 4 is also caused, so that the actual temperature of the pot 1 cannot be known. In addition, the control accuracy of such a contact temperature sensor 4 is only ±5 ℃, and the accuracy is poor.
