Embodiment 1

[0039] A food processor such as figure 1 As shown, the food processor 1 may include a heating cup 11, a heating device 12 and a main control unit 13. The heating device 12 is used to heat the heating cup 11; A temperature sensor 15 is provided; the temperature sensor 15 is connected to the main control unit 13;

[0040] A temperature sensor 15 is used to detect the temperature of the heating cup 11;

[0041] The main control unit 13 is used to compare the collected temperature of the heating cup 11 with the preset first temperature threshold T1; when the temperature of the heating cup 11 is greater than or equal to the preset first temperature threshold T1, it is determined that the food processing The machine 1 is dry burning and controls the heating device 12 to stop heating;

[0042] Wherein, the first temperature threshold T1 is determined by the protection temperature T2 of the overheat protection device, and the difference T2-T1 between the protection temperature T2 an...

Embodiment 2

[0050] In this embodiment, on the basis of the first embodiment, a dry burning judgment scheme is added.

[0051] Optionally, the main control unit 13 is further configured to: before judging whether the food processor is dry-boiling according to the first temperature threshold, judge whether the food processor 1 is dry-boiling according to the temperature rise rate of the heating cup 11 .

[0052] In the embodiment of the present invention, since the heating device 12 (such as a heating tube) will have a certain thermal inertia when heating, and there is a certain hysteresis in the detection of the temperature sensor 15, when the current temperature T is detected by the temperature sensor 15, the heating The actual temperature of the cup 11 is generally greater than T, and when the power of the heating device 12 is larger, the rate of temperature rise is faster, and the hysteresis of the temperature detected by the temperature sensor 15 is more obvious, and the thermal inertia...

Embodiment 3

[0065] The solution of this embodiment further limits the value ranges of the second temperature threshold T3 and the collection period t on the basis of the second embodiment.

[0066] Optionally, the second temperature threshold T3 satisfies: T3≥100°C.

[0067] In the embodiment of the present invention, when the temperature of the heating device 12 is lower than 100°C, the conduction effect of water is limited, and the temperature rise rate of the heating device 12 is relatively close. Misjudgment is caused. When the temperature of the heating device 12 exceeds 100°C, the water conduction effect is more obvious. When there is water, the temperature rise rate of the heating device 12 is relatively slow and gradually tends to be stable. When dry burning, the temperature rise rate of the heating device 12 It is faster and the rising speed remains basically the same, so the dry burning situation can be judged quickly and accurately according to this difference.

Abstract

The embodiment of the invention discloses a food processor. The food processor can comprise a heating cup, a heating device and a main control unit, and the heating device is used for heating the heating cup; an over-temperature protection device is arranged on the heating cup, and the food processor is still provided with a temperature sensor; the temperature sensor is connected with the main control unit, which is used for detecting the temperature of the heating cup; the main control unit compares the collected temperature of the heating cup with a preset first temperature threshold value T1; when the temperature of the heating cup is greater than or equal to the preset first temperature threshold value T1, the heating device is controlled to stop heating; the first temperature threshold value T1 is decided by the protection temperature T2 of the over-temperature protection device, and the difference value T2-T1 of the protection temperature T2 and the first temperature threshold value T1 meets that T2-T1 is greater than or equal to 40 DEG C. The food processor solves the problem that the over-temperature protection motion of a fuse link makes the food processor not work normally, dry heating is avoided, the failure rate is reduced, and the user experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to cooking equipment design technology, especially a food processor. Background technique [0002] At present, the general heating protection scheme for food processors (such as soybean milk machines) is: install an overheating protection device on the bottom or side of the heating cup body. The overheating protection device is generally a self-resetting thermostat and a thermal fuse. On the one hand, the cost is high. On the other hand, with the further strengthening of national standards, it can no longer meet the requirements of national standards; and there are certain safety hazards in self-resetting thermostats. Therefore, the current scheme generally uses two fuses for heating protection. However, due to the non-recoverable property of the fuse link, the use of two fuse links will cause the food processor to fail to work normally after the fuse link is blown, thereby increasing the failure rate of the ...
