This is a field for controlling the canceling key of the electric pressure thermal cooker which prevents the loss of human body or property by discharging the steam of high temperature and high pressure or the contents of the cooking when the cooking is canceled by opening the steam to the outside. .

The electric pressure thermal cooker is connected to the inside and the outside of the cooker when the lid of the cooker to form a vent for discharging the steam inside when the steam is discharged, the vent is controlled by the solenoid valve Configure the method of control. In this connection, pressing the cancel key during cooking cancels the process in progress, opens the solenoid valve, and discharges steam and cooking contents including water inside the electric pressure thermal cooker through the tube of the solenoid valve. At this time, since the temperature of the steam and the cooking contents discharged through the solenoid valve exceeds 100 ℃ can cause a burn to the human body, a number of research and development has been progressed.

The following is a known technology related to the cancel key control of the electric pressure rice cooker.

Korean Patent No. 10-0843762 relates to a method for controlling a cancel key of an electric pressure cooker and an electric pressure cooker using the same, wherein a temperature of an inner pot (a pot accommodated inside the electric pressure cooker) is a constant temperature (for example, 85 ° C.). ) If the cancel key is pressed for more than a certain time (for example, 2 seconds), the process is canceled.If the inner pot is low or the solenoid valve is open, the process is canceled immediately when the cancel key is pressed. It is a technology that enhances stability in use, but the process is canceled simply by pressing only the cancel key input method of the control window for a certain time, so that the steam containing high temperature-high pressure is discharged as it is discharged as it is. There is a high risk of human and property loss due to cooking contents.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 to 3 showing embodiments of the present invention.

First, the soaking process (S200), heating process (S300, heating 1, heating 2, boiling heating process), steaming process (process consisting of S400, steam 1, steam 2, steam 3, as shown in Fig. 2), the warming process ( In the cooking process (S100) of the electric pressure thermal cooker 10 operating sequentially according to a predetermined algorithm (S500) may cause a case of canceling the cooking due to the wrong menu selection, such as the need for cooking is not necessary. There is a conventional method for canceling the control of the electric pressure thermal cooker 10, if the cancel key is input immediately discharge the steam inside the electric pressure thermal cooker 10 to the outside to perform a cancellation function and accordingly discharged high temperature- Human or property damage caused by high pressure steam or cooking contents has been caused.

That is, as shown in Fig. 2, the cooking process during the soaking step (S200), the heating step (S300) and the heating step (S500) is relatively stable at 60-98 ° C in the electric pressure thermal cooker (10), and steam is discharged. There is no fear that the moxibustion 3 in the moxibustion process (S400) is a step in which the solenoid valve 20 is opened to discharge steam after the moxibustion 2, so cancellation of cooking is insignificant, while heating 2 and heating in the heating process (S300) are performed. In the boiling heating and the moxibustion process (S400), the cooking cancellation during the moxibustion 1 and moxibustion processes is a state in which the inside of the electric pressure thermal cooker 10 has a high temperature and high pressure, so if the steam of high temperature and high pressure is discharged as it is, the high temperature and high pressure of water is included. In addition to steam, the contents of cooking are also discharged, causing a loss of human or property.

Thus, the present invention starts the cooking by entering the cooking key during the cooking process (S100) using the electric pressure thermal cooker 10 as shown in FIG. 1 and the cancellation key occurs when the soaking process (S200) is performed. When input, the soaking process (S200) has a relatively stable value of 25 ~ 60 ℃, internal pressure 1 ~ 1.25 atm of the electric pressure thermal rice cooker 10, and performs the step (a) to finish cooking immediately.

In addition, when the canceling factor is not generated during the soaking process (S200) and the canceling factor is generated during the heating process (S300), and the cancel key is input, the electric heating load supplied to the electric pressure thermal cooker 10 is immediately stopped. And, if the internal pressure or the internal pressure of the electric pressure thermal cooker 10 is less than 95 ~ 100 ℃ or the internal pressure is less than 1.5 ~ 1.8 atm by judging the internal temperature or internal pressure of the electric pressure thermal cooker 10 Open the solenoid valve 20 which is a device for discharging the steam to discharge the steam inside. In addition, if the internal pressure of the electric pressure thermal cooker (10) is 95 ~ 100 ℃ or more or the internal pressure is more than 1.5 ~ 1.8 atm or lower the internal temperature of the electric pressure thermal cooker (10) to 95 ~ 100 ℃ or the internal pressure 1.5 ~ After lowering naturally to less than 1.8 atm, the solenoid valve 20, which is a device for discharging steam inside the electric pressure thermal cooker 10, is opened to discharge steam from the outside and finish cooking.

This is because the internal pressure of the electric pressure thermal cooker 10 or more than 95 ~ 100 ℃ or the internal pressure of 1.5 ~ 1.8 atm or more because the steam pressure is too high compared to the outside of the electric pressure thermal cooker 10, the solenoid valve ( 20) When the steam inside the electric pressure thermal cooker 10 is opened to the outside, steam and cooking contents, including water, are discharged to the outside, resulting in a loss of human body or property, so that the electric pressure thermal rice cooker 10 This is to discharge steam in a stable state by naturally dropping the hot-high pressure state. In addition, since the internal pressure also decreases when the internal pressure of the electric pressure thermal cooker 10 decreases because of physical properties having a proportional relationship with each other, the internal temperature or internal pressure of the electric pressure thermal cooker 10 in the present invention. The internal temperature 95 ~ 100 ℃ and the internal pressure of 1.5 ~ 1.8 atm, which is a standard for determining whether the natural fall processing of It is possible to determine whether or not the internal temperature or internal pressure is naturally lowered by judging one or more physical characteristics of the temperature or internal pressure.

In addition, when the canceling factor does not occur in the heating step (S300) and the canceling factor occurs during the moxibustion step (S400), when the cancel key is input, the solenoid valve 20 which is a steam discharge device of the electric pressure thermal cooker 10 is provided. The following control method is decided according to whether or not) is closed. That is, as shown in Fig. 2, the moxibustion process (S400) is performed by dividing moxibustion 1, moxibustion 2, and moxibustion 3 because moxibustion 3 is a process of discharging steam in the electric pressure thermal cooker 10 to the outside by opening the solenoid valve after moxibustion 2. Since the cooking process is quite completed, the cooking cancel key input after the moxibustion 3 in which the solenoid valve 20 is open is insignificant and thus performs the warming process (S500), and the moxibustion 1 or the moxibustion 2 in which the solenoid valve 20 is closed. When the cancel key input at the input of the cancel key during the heating process (S300), since the inside of the electric pressure thermal cooker 10 is in a high temperature-high pressure state, the internal temperature of the electric pressure thermal cooker 10 is 95 to 100 ° C or higher. As the internal pressure is 1.5 ~ 1.8atm or more electric pressure insulating rice cooker (10) after the internal temperature naturally lowered to 95 ~ 100 ℃ or internal pressure is lowered to less than 1.5 ~ 1.8atm, electric pressure insulating rice cooker (10 ) Soleno, a device that discharges steam inside Open the valve 20 to discharge the steam to the outside and finish cooking.

In addition, when the internal temperature of the electric pressure thermal cooker 10 in the heating process (S300) is 95 ~ 100 ℃ or more or the internal pressure is 1.5 ~ 1.8atm or more and the solenoid valve 20 during the steaming process (S400) is closed The internal temperature and internal pressure of the electric pressure thermal cooker 10 was measured in relation to time, and the results shown in Table 1 were obtained. In other words, the internal temperature and the internal pressure of the electric pressure cooker due to the natural fall performed in the above case during the heating step (S300) or the moxibustion step (S400) are stable after the natural fall time is 13 to 25 minutes (preferably 20 minutes). In this case, the solenoid valve 20 is opened to indicate that steam can be discharged, and the present invention has a controllable effect in relation to temperature, pressure, and time in a control method of discharging steam after input of a cooking cancel key.

Table 1.

The present invention is a hot-high pressure steam or cooking contents inside the electric pressure insulation rice cooker 10 immediately even if a canceling factor occurs during the cooking process using the electric pressure insulation rice cooker 10 as the solution means. It is not discharged to the outside, the electric pressure insulating rice cooker (10) inside the predetermined temperature or constant pressure for a predetermined time so that the high temperature-high pressure after a natural drop down and open the solenoid valve 20 to discharge to the outside ( 10) There is an effect to prevent internal high temperature-high pressure steam or cooking contents to be discharged as it is, causing human or property loss.
