JPH0480525A - Device of preventing empty cooking in grill - Google Patents

Abstract

PURPOSE:To improve the safety by a method wherein an empty cooking prevention device is comprised of a gradient judging part for measuring a gradient of temperature increasing, comparing the measured gradient with a predetermined value and judging it and a control device for terminating an electrical energization when the measured value exceeds the predetermined value. CONSTITUTION:When a switch 8 is turned on, a temperature within a grill is increased at a specified gradient and after a specified period of time (t1) elapses, a gradient judging part 11 judges a gradient. In the event that the gradient is less than a predetermined value A, a present temperature is judged by a temperature judging part 13. If the temperature is lower than a predetermined value Ta capable of producing any burning, an electrical energization is continued and the gradient is judged again. In the event that there is water in a water pan, the temperature does not increase by more than a specified value and in turn if there is no water in it, the temperature in the grill is increased more and more to exceed the predetermined value Ta, so that an electrical energization for the heater 4 is stopped.

している。(Example) Reference numeral 1 denotes a grill storage, which has an opening/closing door 2 on the front and an exhaust port 3 on the rear of the top surface. 4 is a heater (
(heat source), and energization I# is controlled by a control device to be described later. Reference numeral 5 indicates a grill on which food such as fish is placed, and reference numeral 6 indicates water I placed on the bottom of the refrigerator. Reference numeral 7 denotes a temperature sensor such as a thermistor attached to the back side of the bottom of the grill chamber 1, which sends a temperature signal to the control device. The temperature detector 7 is not limited to this location, but may be provided at any other suitable location within the refrigerator. 8
is the switch to start cooking. Reference numeral 9 denotes a control device, which includes a temperature detection section IO that reads the temperature detected by the temperature detector 7, an inclination detection section 11 that measures the slope of temperature rise, and an inclination detection section 1.
a slope determination unit 12 that determines whether the slope ΔT/Δt measured in step 1 exceeds a predetermined value A, and a temperature T detected by the temperature detection unit 10 when the slope is less than or equal to a predetermined value A. Temperature judgment 813 determines whether or not the detected temperature exceeds Ta, and if the detected temperature exceeds a predetermined value Ta, the power supply to the heater 4 is stopped, and if t and ma are less than Ta, the power supply to the heater 4 is continued. An energization control unit 14 counts the time when the slope exceeds a predetermined value A, and turns on the energization 1118 at the time of count up.
It has a timer 15 that outputs a energization stop signal to the first section 14.

のであり、実使用り問題はない。First, when switch 8 is turned on (Sl), energization starts (
S2), the temperature inside the refrigerator increases with a constant slope. After a certain period of time 11 (for example, 5 minutes), the slope determination unit 1
1 determines the slope (S3.S4). Fish is grilled here 5
If it is placed on a slope, the slope is gentle and the specified 4
It becomes 1fA or less. If the slope is below the predetermined value A, then the temperature determining section 13 determines the current temperature (S5); if the temperature is below the predetermined value Ta, which may cause a fire inside the refrigerator,
The energization control unit 14 continues energization (S6), and returns to step s4 again to determine the inclination. By the way, if there is water in water l, as shown by solid line a in Figure 3,
The temperature will no longer rise above a certain point. However, when there is no water in the water I, the temperature inside the refrigerator continues to rise, as shown by the broken line, and eventually exceeds the predetermined value Ta. If this happens, there is a risk that the oil on the water 116 will catch fire, so the temperature determination unit 13 outputs a energization stop signal to the energization control unit 14 to stop energizing the heater 4 (
S5. S7), When baking dried fish, do not add water,
Usually, the food is baked before the internal temperature rises to the predetermined value Ta, and there is no problem in actual use.

ところで、使用者が誤って魚も水も入れずにスイッチ８
を入れてしまうことも考えられる。By the way, the user accidentally turned on switch 8 without adding fish or water.
It is also possible to include .

時間以上続いたときに通電停止出力を出すものである。If oil from the previous time remains on the water level at this time, there is a risk of a fire as described above. In this case, there is no fish or water, so the temperature inside the refrigerator rises rapidly (3rd stage).
When the tilt detection section 11 detects this (see the dashed line C in the figure), the timer 15 is activated. When the timer 15 counts a certain period of time tz (for example, 3 minutes), the energization control unit 14 stops energizing the heater 4 (38.3
7), that is, this timer 15 is reset in the event of a momentary steep slope, and outputs an energization stop output when the steep slope continues for a certain period of time or more.

従って魚も水もない場合も、安全にヒータ４への通電は
停止せられる。Therefore, even if there is no fish or water, the power supply to the heater 4 can be safely stopped.
