Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressure cooker equipped with an inner lid that forms a sealed container together with a pot, and an outer cover that covers the inner cover, and in which the outer cover opens when the pot and the inner cover are fully engaged. The purpose of this invention is to provide a highly safe pressure cooker that prevents such problems.

Until now, no pressure cooker with an outer lid has been proposed,
When considering transportation and heat retention, it is a good idea to provide an outer lid. Moreover, it is convenient to use if the outer cover and the inner cover can be opened together. However, when the pot and the inner lid are in a normally engaged state and the user attempts to open the outer cover, the pot is lifted and the outer cover opens slightly. In this case, the pressure valve attached to the inner lid would tilt, and there was a danger that the steam inside the pot would suddenly and forcefully blow out.

The present invention aims to prevent steam from suddenly and forcefully spewing out by preventing the outer cover from opening when the pot and the inner cover are in a normal state of engagement. This will be explained with reference to the attached drawings.

In the figure, 1 is the main body, 2 is a heating element placed at the bottom of the main body, 3 is a pot detachably housed in the main body 1, and 4 is a pot 3
Nono-Nking placed on the upper opening edge of the sti pot 3
': An inner lid that airtightly covers the surface opening through a seal. This inner lid 6 is horizontally rotated to engage the pot 3 in a locking manner, thereby forming a closed container. Reference numeral 6 denotes a heating element for the lid, which is provided on the lower surface of the inner lid 5f: the cover 3, and the outer lid 7. The outer cover 7 has one side pivoted to the upper part of the main body 1, and a lever 8 which can be freely engaged and detached from the upper part of the other side of the main body 1 is provided on the other side. 9 is the inner lid 6
It is an operating lever that is fixed to and protrudes from the outside, and when manually rotated horizontally, the inner cover 5 is rotated horizontally, and the inner cover 5 is rotated horizontally.
and the pot 3 can be engaged and detached. 10ij a power supply section provided at the lower side of the main body 1; 11 a notch formed in the pot 3 and the inner lid 5 for bayonet engagement between the pot 3 and the inner lid 6; 12 a lever 8 and an operating lever 9; These are notched locking portions formed in the two parts, and engage with each other.

13 is a heat-sensitive device that senses the temperature of the pot 3 and controls the supply of electricity to the heating element. Further, the inner lid 5 is provided with a pressure valve (not shown) extending through the outer lid 7 to keep the pressure inside the pot constant.

In the above configuration, when the outer cover 7 is closed, the lever 8 is moved to the main body 1.
engage with. In this state, when the operating lever 9 is horizontally rotated from the A position to the B position as shown in FIG. 2, the pot 3 and the lid 5 engage in bayonet engagement, forming a closed container. At this time, since the notch locking portion 12 of the lever 8 is engaged with the notch locking portion 12 of the operating lever 9, the engagement between the lever 8 and the main body 1 will not come off. do not have.

Therefore, when the pot 3 and the lid 6 are in a normally engaged state, the outer lid 7 does not open. Therefore, steam does not suddenly blow out from the pressure valve, making it safe. When opening the outer cover 7,
By horizontally rotating the operating lever 9 from the B position to the A position as shown in FIG. 2, the pot 3 and the lid 6 are brought into a disengaged state.
When the lever 8 is operated to release the engagement between the lever 8 and the main body 1, the outer cover 7 can be opened. In addition, at this time, the outer cover 7
The inner lid 5 is also opened at the same time.

In the above embodiment, the cutout locking portion 12II'i is formed on the lever 8 and the operating lever 9, but it may be formed on only one of them.

As is clear from the above description, according to the present invention, when the pot and the inner lid engage in bayonet engagement, the lever and the operating lever are engaged, so the lever is operated to engage the main body. It cannot be released and the outer lid is prevented from opening, thereby preventing the pressure valve from tilting and steam inside the pot from violently gushing out, thereby providing a safe 6° pressure cooker.
