Description

Induction heating electric pressure cooker with condensate evaporation structure

The present invention relates to an induction heating type electric pressure cooker having a condensate evaporation structure.

An electric pressure cooker is a home appliance that uses electricity as a heating source to perform a cooking function. The electric pressure cooker maintains the inside of the oven at high pressure to keep the heating temperature higher than normal atmospheric pressure, so that it can cook quickly. there is.

1 is a cross-sectional configuration diagram showing an electric pressure cooker according to the prior art.

Referring to FIG. 1 , the electric pressure cooker includes an oven 10 , a body case 12 in which the oven 10 is seated, a lid 14 for opening and closing the oven 10 and the body case 12 , an electric device And, is configured to include a vapor discharge device for adjusting the pressure in the oven (10).

The electric device of the electric pressure cooker includes a working coil 16 that is mounted on the main body case 12 to generate an induced current during cooking, and a heater 18 that generates heat.

The steam discharge device is automatically opened during cooking to lower the pressure in the oven 10, a solenoid valve 20, and a poise valve that is opened and closed by the pressure in the oven 10 to keep the pressure in the oven 10 constant (poise valve, 30).

During cooking of the electric pressure cooker configured as described above, an eddy current is induced in the oven 10 by the working coil 16, and the oven 10 is gradually heated due to the eddy current, so that the rice grains are soaked and cooked.

At this time, the upper lid of the oven 10 is bound to the lower surface of the top plate by a binding device (not shown), and the solenoid valve 20 and the poise valve 30 constituting the vapor discharge device are maintained in a closed state. Therefore, the pressure inside the oven 10 becomes higher than atmospheric pressure.

As the pressure inside the oven increases, the temperature of the rice also rises to a temperature higher than the boiling point (about 100℃) at normal atmospheric pressure, so quick cooking is achieved.

After that, when the boiling and cooking processes are completed, the steaming process is performed for a certain time while the heating by the working coil 16 is stopped, and the water vapor inside the oven 10 is discharged to the outside by the solenoid valve 20 The warming process is carried out in a state where the pressure is lowered.

In the conventional electric pressure cooker configured and operated as described above, after the cooking and steaming process is performed in a state where the pressure inside the oven is increased, the internal water vapor is discharged through the steam discharge device such as the solenoid valve 20 at the upper end of the lid 14 . is emitted as

Some of the water vapor discharged through the solenoid valve 20 and the poise valve 30 is vaporized, but a significant number is not vaporized and flows to the outside of the lid 14 or is filled in the side drain through the condensate flow path inside. . In this way, the condensate flow path inside the lid and the condensate filled in a separate drain container should be emptied and washed quickly for hygiene reasons.

However, in conventional electric pressure cookers, since the lid is assembled in a hinge type on either side of the main body case 12 , most of the structures can only open and close the lid 14 and are not separated. Therefore, the lid 14 of the electric pressure cooker, which is not separated, can only wash the outer surface and the drain container, and the inner space and the condensate flow path cannot be washed, so hygiene problems have arisen.

In addition, as shown in Korean Patent Publication No. 10-1839068 (2018.03.09), etc., the conventional electric pressure cooker had to form the condensate flow path as short as possible because it is impossible or difficult to wash the condensate flow path. Accordingly, most of the condensate drains are configured in the peripheral portion of the hinge to which the lid is coupled, in particular, in the rear portion of the hinge. As such, since most of the condensate drain tube is configured on the back or rear side of the pressure cooker, washing and management of the condensate drain tube has no choice but to be neglected.

On the other hand, a technique for controlling the condensate flow path inside the lid using a jog dial has been proposed as in Korean Patent Application Laid-Open No. 10-2016-0112017 No. 10-2016-0112017 (2018.03.09). However, the conventional condensate flow path control structure only facilitates the management of the condensate flow path including the assembly structure of the jog dial, but there is still a limit to emptying and managing the condensate drain tank.

The present invention aims to provide an induction heating type electric pressure cooker that allows the lid to be separated when the lid of the electric pressure cooker is opened, so that the condensed water evaporation structure inside the separated lid and the external surface can be easily washed do.

In addition, the present invention is an induction heating type electric pressure cooker that enables the treatment of steam and condensed water without installing a separate condensate drain container by forming a vapor discharge part such as a poise valve on the upper part of the lid and forming a condensed water evaporation structure inside the lid. is intended to provide

In addition, the present invention provides an induction heating type electric pressure cooker in which a waterproof space is provided inside the lid so that an electric circuit can be mounted and applied in the waterproof space, so that the upper end of the lid and the inner space can be easily washed with tap water or a washing solution. intended to provide
