The present invention relates to an electronic automatic cooking container for notifying completion of cooking by generating an alarm sound when cooking is completed.

Until now, the cooking vessel had no function of notifying the completion of cooking, so the user always had to stand by the cooking vessel to judge the process of cooking by smell, taste, and visual judgment. In addition, when the user forgets to cook during the cooking process, there is a risk of fire because there is always a risk of burning the cooking. In addition, people who are poor at cooking have the disadvantage of cooking less or cooking too much.

Of course, the prior art proposed to solve the disadvantages of the conventional cooking vessels such as to generate a beep sound by using the pressure and flow of the steam to be ejected when the cooking enters the boiling state to eject the steam. But it only had the function of notifying that it was boiling, but could not tell whether cooking was done.

In other words, none of the conventionally proposed cooking vessels indicate that cooking has been completed.

The present invention has been devised to solve the disadvantages of the prior art as described above, even if the dishes are put up and forgotten, it is possible to know that cooking is completed by an alarm sound notifying cooking completion, so even those who are not good at cooking can easily cook. Not only will you be able to do this well, but you will not have to worry about burning your food.It is safe and you can do other things such as washing clothes, baby watching, reading, and watching TV with the cooking vessel on the stove. The technical configuration according to the accompanying drawings in detail as follows.

The present invention is installed in the position where the steam is ejected as shown in Figs. 3 and 4 to detect whether the steam is ejected or installed in the lid of the cooking vessel as shown in Fig. 5 to detect the temperature or pressure in the container or the temperature of the container itself A sensor 11 for detecting boiling of the contents, a sensor 10 for receiving a signal from the sensor 11 to determine the ingress of boiling state, and outputting a signal when boiling, and the detecting unit 10 when boiling Is started by the output signal of the timer, and the timer is set by the operation of the setting unit 40, and is started by the output signal of the timer unit 20 and the timer unit 20 which outputs a signal when the setting time is completed. And a timer sound which is activated by a signal of another timer unit 30 and a time signal set by the operation of the setting unit 40 and the detection unit 10, the timer unit 20, and another timer unit 30. On the output signal of the generator 50 and the beep generator 50 Generating a negative and consists of a speaker 51, a first-degree control circuit and the control circuit is built-in handle (70) consisting of notifying the completion of cooking.

In the control circuit diagram of the present invention as shown in FIG. 1, the output signal of the sensing unit 10 output when the dish is boiling is introduced only into the timer unit 20 as shown in FIG. 2, and not into the beep generator 50. You can also configure it.

That is, FIG. 2 is a circuit diagram of generating alarm signals at fire extinguishing and cooking completion points, respectively. In contrast, FIG. 1 first generates alarm signals for a predetermined time when cooking is detected in boiling state. It is a circuit configuration in which a signal for lowering the fire power to lower the signal is sent and a beep sound is generated later at the fire extinguishing point and the cooking completion point.

In addition, in FIGS. 1 and 2, in order to inform the user only of the fire extinguishing point of the heating device in order to lower the manufacturing cost of the control circuit, the timer unit 30 may be configured to be omitted.

3 is an embodiment of the present invention installed in the pressure cooker as an embodiment of the present invention is a state diagram in which the control circuit as shown in FIG. 1 or 2 in the handle 70 of the cooker lid 60, the rotary weight 61 The sensor 11 is positioned at the position at which water vapor is ejected from the (61), and the knob (70) above the control knob for setting the time of the timer unit (20, 30) by the time setting unit 40 ( 1) was installed to set the time according to cooking.

Here, reference numeral 72 denotes a known " water vapor discharge port " for discharging water vapor by the operation of the water vapor ejection button 71.

On the other hand, after the control circuit is embedded in a separate case 80 as shown in FIG. 4, the case 80 can be attached to or detached from the handle 70 by forming the engaging pieces 82 at the same time and forming protrusions 81 on both bottom surfaces thereof. It can also be configured.

At this time, of course, the sensor 11 is positioned where the water vapor is ejected and the adjusting knob 1 is positioned above the case 80. Reference numerals "71" and "72" are known "water vapor ejection buttons" and "water vapor ejection openings", respectively.

In the present invention configured as described above, a case where the circuit configuration of FIG. 1 is installed as shown in FIG.

Example 1

Put the cooking contents in the cooker, close the lid, and then designates the type of contents to be cooked by the operation of the time setting unit 40.

That is, when the knob 1 of the time setting unit 40 is set to the "cooking" display, the timer unit 20 boils in a state where steam is ejected from the cooker to complete the "cooking". The "boiling duration" of the cooking to be continued is set automatically, another timer 30 is the time required to take the moxibustion without opening the lid of the pressure cooker after the heating is stopped in the cooking "moxibustion" Enter time "is set automatically.

If the cooking of the ribs, if you set the control knob (1) of the setting section 40 to "steam ribs" timer 20, the "boiling duration" of the steamed ribs is automatically set and another timer unit 30 ) Will be set automatically "steaming time" of ribs steamed. As described above, the "boiling duration time" and "moxibustion time" can be determined by experimentally measuring each menu (or cooking type) in advance, and converting the data into a timer unit during the menu selection operation of the setting unit 40. In (20) and (30), the data of the menu (or cooking type) are respectively set automatically.

That is, the menu (type of cooking) is designated by the operation of the adjusting knob 1 of the setting unit 40 and the cooking vessel is heated with a gas or electric burner.

When the temperature of the contents is increased by continuous heating of the burner, water vapor is finally ejected, and the rotary weight 61 of FIG. 3 (or FIG. 4) rotates to discharge water vapor in all directions.

Then, the hot temperature of the steam (if the sensor is a temperature sensor) raises the temperature of the sensor 11, and soon the cooking unit 10 detects that the cooking is boiling.

Then, the detection unit 10 transmits a signal to the timer unit 20 to start the timer unit 20 and at the same time sends a signal to the beep generator 50 to generate an alarm signal sound for a predetermined time.

Therefore, by the primary alarm sound, the user lowers the fire power (as a high fire power is not necessary in the boiling state). The cooking vessel then continues to discharge steam while being heated at low thermal power, and the timer unit 20 performs the time set by the setting unit 40.

Finally, when the set time of the timer unit 20 is completed, a signal is output from the timer unit 20 to the beep generator 50 and a second alarm sound is generated for a predetermined time. The user then stops heating completely this time.

In addition, the output signal of the timer unit 20 also flows into another timer unit 30 so that the timer unit 30 continues another time set by the setting unit 40 ("moxibustion time"). .

Finally, when the set time of the timer unit 30 is completed, the timer unit 30 sends an output signal to the beep generator 50 to generate the third alarm sound.

That is, a beep sound is signaled to indicate that all cooking is completed, so the user opens the lid of the cooker by the third beep to eat rice. That is, you can eat the most cooked and steamed rice.

In addition to cooking rice, steamed pork ribs, steamed rice cakes… It is also possible to cook various menus using the cooking vessel of the present invention as described above.

Here, as shown in the circuit diagram of FIG. 2, the primary signal sound for notifying the boiling state may not only cause generation, but also may replace the primary signal sound with water jet noise.

In addition, the beep signal indicating the fire extinguishing point of the fire may also be generated continuously until the user presses the stop button (not shown).

The above is the case where the sensor 11 is comprised by the temperature sensor in the circuit block diagram of this invention.

In the case where the sensor 11 is a humidity sensor, the moisture of the steam to be ejected is sensed to detect boiling of the steam by detecting humidity of the boiling state of the cooking unit 10 by detecting the boiling state of the cooking unit 10. In addition, when the sensor 11 is an acoustic sensor, the sensor 10 detects whether the cooking is boiling by detecting continuous jet noise of water vapor.

As such, when the sensor 11 is a humidity sensor, it is a matter of course to clean the moisture from the sensor 11 on the heating line of the dish and then start cooking. In this case, when the cooking boils and the rotary weight 61 rotates and the steam is ejected, the water vapor is detected by the humidity sensor, which is immediately detected as a boiling state by the sensing unit 10 and the timer unit 20 and another timer. The unit 30 and the signal generator 50 are operated.

In addition, the sensor 11 of the present invention can also be installed to be in contact with the lid of the cooking vessel as shown in FIG. In this case, the sensor 11 detects the temperature of the lid 60 as a temperature sensor and allows the sensing unit 10 to determine the boiling state of the dish. In addition, the sensor 11 is installed on the lid 60 but the lid is closed. The sensing part of the sensor can be configured to be located in the lid so that the internal temperature can be detected.

In addition, in FIG. 5, the sensor 11 may be configured as a pressure sensor that senses the pressure inside the cooking vessel. In this case, the configuration and operation of the basic control circuit are the same as those of FIGS. 1 and 2.

However, it is possible to configure by adjusting the sensitivity of the sensing unit 10 to output a signal from the pressure inside the cooking vessel at the point where the steam is ejected experimentally.

The electronic automatic cooking container of the present invention can be easily applied to cooking vessels of general pots as well as pressure cookers, and when applied to general pots without the rotary weight 61, the temperature of the sensor 11 as shown in FIG. It is easy to carry out by constructing a sensor and sensing the space temperature (inside the cooking vessel) of the lid or the lid of the pot.

In addition, the tone is changed every time the 1st, 2nd, and 3rd (in the case of FIG. 2) up to the 2nd beep in the case of FIG. 1 control circuit. Of course, you can judge the completion point of cooking.

As described above, the present invention is the first to lower the fire power saving point, fire extinguishing point, cooking completion point (or digestion set point and cooking completion point, or fire extinguishing point) to the user to enable the most delicious cooking, mind while cooking It has the effect of providing a very convenient function that makes it possible to work and not to burn or fire.
