Gas stove with lifting type dry-boiling prevention temperature sensors and control method thereof

Abstract

The invention relates to the technical field of kitchen appliances, in particular to a gas stove with lifting type dry-boiling prevention temperature sensors and a control method thereof. The gas stove comprises the temperature sensors, a lifting mechanism connected with the corresponding temperature sensors and used for driving the temperature sensors to rise and all and a control system connected with the lifting mechanism and used for controlling the temperature sensors to rise and fall. The gas stove further comprises weight sensors used for acquiring weight information. The control systemis connected with the weight sensors. By means of the gas stove and the control method thereof provided by the invention, the weight information of cookware is collected through the weight sensors; the gas stove judges whether the lifting mechanism needs to rise or not according to the collected weight information of the cookware. Accordingly, intelligent rising and falling of the temperature sensors are achieved, and control is simple and reliable.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a gas stove with a lift-type anti-dry-burning temperature sensor, and a control method for the gas stove. Background technique [0002] At present, gas stoves with anti-dry function are provided with a temperature sensor in the center of the burner to detect the temperature of the bottom of the pot 8 . When the temperature detected by the temperature sensor reaches the preset value, it is judged as dry burning, and the work of the cooker is stopped, so as to realize the function of preventing dry burning of the cooker. Usually, when the gas cooker is working, the temperature sensor can be lifted out from the central through hole of the fire cover 5 under the drive of the lifting mechanism and contact with the bottom of the pot 8; driven down into the inside of the cooker to protect the temperature sensor. [0003] However, the current control of the rise and fall of ...

Problems solved by technology

[0003] However, the current control of the rise and fall of the temperature sensor is usually complicated and not intelligent enough

In addition, the rising stroke of the temperature sensor is not effectively controlled, so that the gas stove also has the following defects: (1) The bottom of some pots 8 is concave, so that the compression amount of the spring is too small, and the contact pressure is small, causing the interface Large thermal resistance is not conducive to rapid heat transfer, resulting in large temperature measurement errors; (2) when the rising stroke is insufficient, the pot 8 with a concave bottom of some pots cannot be in contact with the temperature sensor, such as figure 1 As shown; when the rising stroke is too large, the pot 8 protruding from the bottom of some pots is supported by the temperature sensor and cannot be placed stably, as figure 2 (3) In order to make a good contact between the bottom of the pot and the temperature sensor, the bottom of the pot must be in parallel contact with the temperature sensor and pressed down vertically during the process of putting the pot, otherwise the temperature sensor and the bottom of the pot will easily have skewed contact , resulting in a smaller contact area and a larger error in temperature measurement, such as image 3 shown
