In more detail, the inner pot 10 has a cylindrical shape having an upper surface open therein and a predetermined space therein so that cooking objects can be contained therein, and a storage unit 12 in which cooking objects are contained, and a lid 30. It is made of a closed portion 14 which is in close contact by. In this case, the inner pot 10 may be made of a metal material having good thermal conductivity, and a coating film having various functions may be coated on the surface thereof.

The cooker body 20 is in a cylindrical shape, the fitting portion 21 is formed in the center portion so as to fit the inner pot 10 described above, the outside of the various functions of the electric pressure cooker 50 (On) / off ( A switch (not shown) to turn off and a liquid crystal display unit (not shown) and a timer (27 of FIG. 3) to output a rice cooker state are installed. In addition, a sensing unit (not shown) for detecting whether the inner pot 10 is inserted into a bottom surface or a bottom peripheral portion of the fitting portion 21 and a heating unit (not shown) for heating the inner pot 10 and the The temperature sensor 23 for detecting the temperature of the inner pot 10 is installed. Here, the sensing unit and the temperature sensor 23 may be integrally formed.

The lid 30 is hinged to one side end of the rice cooker body 20 so that one end thereof is rotatable to the rice cooker body 20. At this time, the lid 30 is located on the lower side of the hinged portion of the cooker body 20 is provided with a lid opening and closing detection device 25 for detecting whether the lid 30 is opened or closed. Therefore, the lid open / close detection device 25 detects whether the lid 30 is opened or closed and transmits the detected value to the above-described control device 40, and the control device 40 according to the detected value. The operation of the electric pressure cooker 50 is appropriately controlled. In addition, the lid 30 is provided with a steam discharge device 32 that can selectively discharge the steam generated in the inner pot 10 to the outside. In one embodiment, the steam discharge device 32 may be driven when the cooking objects contained in the inner pot 10 is cooked to discharge the steam generated in the inner pot 10 to the outside.

The control device 40 is built in the inside of the cooker body 20, is electrically connected to each of the above-described devices to control the overall operation of the electric pressure cooker (50). Specifically, the control device 40 is the above-described lid opening and closing detection device 25, the temperature sensor 23, the timer 27, the air forced discharge device 33, solenoid device 36, steam discharge device ( 32) is electrically connected to a switch, a liquid crystal display unit, a sensing unit, a heating unit, and the like, and controls the overall operation of the electric pressure cooker 50 by controlling the devices in general according to a preset order and algorithm. In one embodiment, the control device 50 drives the heating unit or the like appropriately to advance the cooking mode and the warming mode. In other words, the control device 50 cooks the cooked food contained in the inner pot 10 through the cooking mode, and stores the cooked cooked food through the warming mode.

On the other hand, the lid 30 is provided with an air passage 37 so as to communicate the inside of the inner pot 10 and the outside of the lid 30. Therefore, the aforementioned air forced discharge device 33 forcibly pumps the air in the inner pot 10 to the outside through the air passage 37.

Hereinafter, with reference to Figure 4, it will be described in detail the control method of the electric pressure cooker of the present invention configured as described above.

4 is a flowchart illustrating a control method of the electric pressure cooker according to the present invention.

First, when the user of the electric pressure cooker 50 closes the lid 30 and then presses any one of the switches outside the cooker body 20, the control device 40 detects a signal generated by pressing the switch. It is determined whether the cooking mode (S61). Therefore, when it is determined that the determination value is the cooking mode, the control device 40 drives the heating unit or the like to proceed with the cooking process (S64), and also drives the solenoid device 36 to install the air flow path installed in the lid 30. The air inflow passage 35, that is, a portion in which air flows into the air passage 37, is sealed in step 37. Therefore, since the solenoid device 36 seals the air inflow passage 35, the high pressure in the inner pot 10 generated in the cooking mode acts on the air forced discharge device 33 installed inside the lid 30. It can't be blocked.

On the other hand, if it is determined that the value detected by sensing the signal generated by the switch is not the cooking mode, the control device 40 determines whether the warming mode (S62). Therefore, if it is determined that the determination value is not the warming mode, it is determined whether it is the initial mode again (S63), and if it is the initial mode, the initial mode is maintained (S65). It is made (S61). When the determination value is determined to be the warm mode, the control device 40 determines whether the sensor, that is, the temperature sensor 23 is 85 ° C. or less (S67). Therefore, if the temperature value is not below 85 ° C., the control device 40 controls the solenoid device 36 to be closed (S66). However, if the temperature value is 85 ° C. or less, the control device 40 has reached the set driving time of the air forced discharge device 33 using the lid open / close detection device 25 or the timer 27 or the like. It is determined whether the lid 30 is opened or closed (S68).

Next, if the set driving time of the air forced discharge device 33 is not reached or the lid is not opened or closed by the determination value, it is again determined whether the temperature sensor 23 is 85 ° C. or less (S67). However, if the set driving time of the air forced discharge device 33 is reached or the lid is opened or closed by the determination value, the control device 40 controls the solenoid device 36 to be opened (S69). Thus, the air inflow passage 35, which was closed by the solenoid device 36, is opened.

Then, when the air inflow passage is opened, the control device 40 controls the air forced discharge device 33 to operate the device (S70). Therefore, the air forced discharge device 33 is forced to pump the air in the inner pot 10 to the outside through the air passage 37. Thus, since the air inside the inner pot 10 is forced to the outside, the inner pot 10 is maintained in a vacuum. Therefore, any problems such as discoloration and off-flavor of the cookware generated by the air introduced into the inner pot 10 are all solved.

Next, the control device 40 determines whether the air forced discharge device 33 has been operated for a predetermined time by using the timer 27 or the like (S71). Therefore, if the air forced discharge device 33 has not been operated for the preset time, the air forced discharge device 33 continues to operate (S70), and, if the air forced discharge device 33 for the preset time, ) Is operated, the operation of the air forced discharge device 33 is controlled to stop the operation (S72).

Therefore, according to the control of the electric pressure cooker 50 as described above, in the warming mode, all the air is discharged inside the inner pot 10 and maintained in a vacuum, so discoloration in the cooked food stored in the inner pot 10 or All problems such as odor and the like are eliminated. In addition, in the cooking mode, the solenoid device 36 is closed and the air passage 37, which is a passage through which air is discharged, is sealed so that the air is forcibly discharged. The device 33 is not directly exposed to the high temperature and high pressure during cooking. As a result, according to the present invention, since the air forced discharge device 33 is not directly exposed to the high temperature and high pressure at the time of cooking, the air forced discharge device 33 can withstand even during cooking where high pressure is generated, As a conventional air forced exhaust device is directly exposed to high temperature and high pressure during cooking, all problems caused by the conventional air forced discharge device are solved.

In other words, according to the present invention, since the air forced discharge device 33 is not directly exposed to the high temperature and high pressure during cooking, the valve is automatically exposed as the conventional air forced discharge device is directly exposed to the high temperature and high pressure of the cooking gas. It will be opened, and through this, it is possible to solve all the problems such as foreign matters that cause the failure of the forced air discharge device in advance.

As described above, according to the electric pressure cooker and the control method thereof of the present invention, the apparatus for forcibly discharging air because the solenoid device is closed in the cooking mode and the air passage, which is a passage through which air is discharged, is sealed. The discharge device is not directly exposed to the high temperature and high pressure during cooking. As a result, according to the present invention, since the air forced discharge device is not directly exposed to the high temperature and high pressure during cooking, the air forced discharge device can withstand the cooking even when high pressure is generated, the conventional air forced discharge device is All problems caused by direct exposure to high temperature and high pressure during cooking have all the effects to be solved.
