Description

RICE COOKING METHOD FOR ELECTRIC PRESSURE RICE COOKER

The present invention can not only cook a lot of sticky rice of the electric pressure thermal cooker, but also the rice grain spreads like a soft rice cooker of the general electric warm rice cooker, the stickiness is low, the taste of the rice cooker of the electric pressure thermal cooker can implement the taste of the pressure cooker The present invention relates to a cooking control method, and more particularly, to a cooking control method of an electric pressure insulating rice cooker capable of cooking rice according to the preferences of various people with a single pressure cooker.

In the conventional method of controlling the electric pressure of the rice cooker, the rice is put into the rice cooker, the lid is closed, and the first step (S1) of raising the steam discharge valve to a constant pressure in a closed state; The second step (S2) of heating the rice for a predetermined time (S2), the third step (S3) of terminating the heating and steaming after a certain time in the above, and steaming before the completion of cooking after the steam in the above The fourth step (S4) of removing the internal pressure by opening the discharge valve, and the fifth step (S5) of proceeding to the warming process after removing the internal pressure from the above.

And the steam discharge valve driving unit circuit for the cooking of the electric pressure thermal cooker for performing the process consisting of each step, as shown in Figure 1, to adjust the pressure of the pressure cooker to cook using the electric pressure thermal cooker The microcomputer 10 for outputting a control signal for the control, the steam discharge valve 30 for adjusting the pressure of the pressure cooker according to the open (OPEN) or closed state (CLOSE) state, and is output from the microcomputer 10 It is composed of a valve control transistor 20 for controlling the operation of the steam discharge valve 30 in accordance with a control signal.

Thus, based on the cooking control pattern shown in Figure 2 with respect to the prior art made of each step as follows.

First, after washing the rice in the warm rice cooker, close the lid and press the start button, the microcomputer 10 of Figure 1 outputs a low signal to the base of the valve control transistor 20.

Then, the valve control transistor 20 is turned off to block the operation of the steam discharge valve 30.

Therefore, the vapor discharge valve 30 is in a closed state as in the? Pattern of FIG. 2.

The steam discharge valve 30 is heated in such a state that it is closed to raise the pressure to a constant pressure as shown in the pattern ⓐ in FIG. 2 (S1), and the rice is cooked under this pressure. This process is referred to as a heating process (S2).

When the heating step is completed, the steam discharge valve 30 is heated while lowering the temperature in a state in which the steam discharge valve 30 is continuously closed as in the pattern ⓓ of FIG. 2. This is called a moxibustion process, and corresponds to the ⓑ pattern in FIG. 2 (S3).

In this moxibustion process, after closing the steam discharge valve 30 in a closed state, the microcomputer 10 outputs a high signal to the valve control transistor 20 two to three minutes before the completion of cooking or immediately after the completion of cooking.

Then, the valve control transistor 20 is turned on to drive the steam discharge valve 30 to open, as shown in the ⓔ pattern of FIG. 2.

Then the internal pressure of the pressure cooker is removed. (S4)

After the internal pressure is removed, you will eat.

When cooked like this, there is little spread of the grain of rice and becomes a conventional pressure cooker rice with a lot of stickiness and persistence.

And, if you do not eat the rice in step S4 will enter the warm mode. (S5)

However, in the prior art as described above, most of the electric rice of the current pressure rice cooker on the market is a lot of stickiness, but lack of spreading or softness to keep warm or to eat rice in the rice bowl to eat rice only water Even though the grains of rice stick together with stickiness and persistence, they are hard to eat. Especially, it is more burdensome for children and the elderly to eat, and people who don't like sticky rice are cooked in a general electric rice cooker and steamed pressure dishes. There is a cumbersome problem, such as in an electric pressure thermal cooker.

Therefore, an object of the present invention for solving the conventional problems as described above is not only possible to cook the pressure of the existing electric pressure thermal cooker and sticky pressure rice, but also spreads the rice as well as the rice of a general electric thermal cooker soft and low stickiness It is to provide a cooking control method of the electric pressure thermal rice cooker to cook rice.

Another object of the present invention is to provide a cooking control method of the electric pressure thermal cooker to be selectively used by the consumer according to the preference.

Still another object of the present invention is to provide a cooking control method of the electric pressure thermal cooker to perform both the function of the electric pressure thermal cooker and the function of the electric thermal cooker.

The present invention for achieving the object as described above is the first step of determining the rice cooker mode after putting the rice in the rice cooker and the lid, and close the steam discharge valve when determined as the electric pressure thermal cooker mode in the predetermined pressure A second step of increasing the heating process and a moxibustion process to open the steam discharge valve as soon as the steam is completely filled and removing the internal pressure, and then proceeding to a warming process; and the first step The fourth step of proceeding the soaking process called the rice for a predetermined time when determining the soft rice mode in the step, and the fifth step of proceeding the heating process by closing the steam discharge valve when the soaking process is completed, the steam at the completion of heating After the discharge valve is opened to remove the internal pressure, the steam is put in for a predetermined time, and the sixth step of proceeding to the warming process is performed.

As described above in detail with reference to the flowchart of Figure 4 the operation and effect of the present invention made of each step as follows.

First, after washing the rice in the warm rice cooker (S101) and close the lid, the user is to make the rice by the electric pressure heat cooker function, or the electric rice heat cooker mode or whether the enviable rice by the electric rice cooker function or Decide the soft rice mode, and press the start button (S102).

Then, the microcomputer 10 of FIG. 1 checks whether the mode determined by the user is an electric pressure thermal cooker mode or a soft rice mode.

When the user selects the electric pressure thermal cooker mode, as described in the prior art, by applying heat to the steam discharge valve 30 in a closed state (S104), as shown in the © pattern of FIG. After heating up to a constant pressure as in the pattern ⓐ in Fig. 2 and performing a heating process to cook rice (S105).

After the heating process, the steam discharge valve 30, as shown in the ⓓ pattern of FIG. (S106)

In this moxibustion process, after closing the steam discharge valve 30 in a closed state, the microcomputer 10 outputs a high signal to the valve control transistor 20 two to three minutes before the completion of cooking or immediately after the completion of cooking.

Then, the valve control transistor 20 is turned on to drive the steam discharge valve 30, and as shown in the ⓔ pattern of FIG. 2, open to remove the internal pressure of the pressure cooker. (S107)

When cooked like this, the rice is less spread and sticky and sticky pressure cooker rice is a lot.

And, if you do not eat rice in the above will enter the warming process. (S108)

In step S103, if the user selects a soft rice mode for making rice soft and soft and low rice, the microcomputer 10 first heats the electric pressure in a state in which the steam discharge valve 30 is opened to call rice. Add a soaking process that is not included in the cooking process of the rice cooker.

That is, the microcomputer 10 outputs a control signal in a high state to the valve control transistor 20.

Then, the valve control transistor 20 is turned on to open the steam discharge valve 30 (S109).

This is the same as the pattern shown in FIG.

Thereafter, as in the pattern ⓕ of FIG. 3, rice is called by maintaining a constant temperature (T2) for a predetermined time (ⓘ). (S110)

After the so called process is completed, the process proceeds to the heating process. In the heating process, the steam discharge valve 30 is made in a closed state as shown in the pattern ⓚ of FIG. 3 (S111), and then a constant temperature (T3) is heated as in the ⓖ pattern. Let's do it.

Then the pressure is raised to a certain pressure, and the rice is cooked by heating in this state. (S112)

When the heating process is finished, the process is switched to the moxibustion process as shown in the ⓗ pattern of FIG. 3, in the case of the conventional electric pressure thermal rice cooker mode, the steam is discharged in a state in which the steam discharge valve 30 is closed, but in the soft rice mode, steam is discharged. The internal pressure is removed while the valve 30 is opened as in the ⓛ pattern. (S113)

Thereafter, after all of the internal pressure is removed, moistening.

When cooked like this, rice can spread well like rice of electric rice cooker, and it can cook rice that tastes like rice cooker with low stickiness.

As described above, the electric pressure thermal rice cooker of the present invention not only cooks rice with a lot of stickiness and tenacity of the existing electric pressure rice cooker, but also makes rice of the electric thermal rice cooker spread so that a soft and low sticky rice can be cooked. Both people who like or dislike rice can use one pressure rice cooker to pick and cook rice that suits their taste.
