Description

{A Cooker Cover For Stone Pots}

The present invention relates to a lid for a pressure stone pot, and more particularly, to a lid for a pressure stone pot with an improved structure to simplify the opening and closing structure of the lid and to conveniently open and close the lid by a handle operation.

In the old days, royal families and noble families used talc stones to cook rice or cook the ingredients, but recently, it has become popular and is often used in restaurants made of granite.

The advantage of such a stone pot is that it does not cool well and can be eaten while cooking the ingredients. If you cook rice in a pot, the rice is cooked evenly and does not boil, so the taste of the rice is good, and the rice does not cool down easily.

These stone pots are increasingly used at home, and like a pressure cooker, they are sealed with a lid so that you can cook more quickly, thereby saving fuel and improving the taste of rice.

As an example of such a stone pot lid, in Korean Patent Publication No. 10-1379001 (registration date March 21, 2014), the opening of the container is covered with a sealing lid, and then the opening of the container is closed using a locking member of the pressing part. However, after the user presses the upper part of the operation part connected to the pressurizing part to the lower part, a stone pot lid for a cooker has a structure in which the container is opened or closed by simply pressing or releasing the button part of the guide member is disclosed.

However, the above-described conventional stone pot for stone pot has a separate operation part and a pressurizing part that are releasably engaged with the frame of the stone pot to be engaged with the edge of the stone pot. There was a big problem, and due to such a complex structure, failures frequently occurred and, if it had to be disposed of, the economic loss was large, resulting in high consumer dissatisfaction.

Korean Patent Publication No. 10-1379001 (Registration Date March 21, 2014)

The object of the present invention is to solve the problem of the dolsot for stone pots of the prior art, the pressure members for sealingly pressing the dolsot to the rim of the stone pot, the displacement to the release position and the pressing position of the opposite ends of the pressing members It is to provide a lid for a pressure stone pot with an improved structure to simplify the coupling structure of the operation unit releasably engaged with and reduce manufacturing cost and facilitate operation.

The lid for a pressure stone pot of the present invention for achieving the above object is a head in which the lower end edge is disposed on the edge of the stone pot, and a pressure position for contacting the edge of the stone pot with the head top, and a release position for releasing it from the close contact in a radial direction Two pressing members disposed in a radial direction on the top of the lid so as to be movable inward and outward and having a holder part engaged with the rims of the lid and the stone pot at the outer end thereof, and the pressing members by engaging the pressing members to displace the pressing members with respect to the lid In the lid for a pressure stone pot having an operation unit,

Each of the pressing members has a long hole formed in the horizontal portion, and a protrusion protruding upward is formed at the inner end thereof,

The manipulation unit includes a cap having a hole formed in the center, a cam plate rotatably provided inside the hole of the cap and engaged with the protrusions formed on each of the pressing members to displace the pressing members to the pressing position and the releasing position, and rotating the cam plate. and a handle coupled to the cam plate with screws to operate the pressing member in the pressing position and the releasing position.

In the cam plate, cam holes having a shape in which one side is curved closer to the center are symmetrically formed with respect to the center of rotation, and protrusions formed on horizontal portions of the respective pressing members penetrate through the cam holes in the cam holes according to the rotation of the cam plate. As the protrusion is displaced by the , the pressing members are displaced to the pressing position and the releasing position to open and close the lid.

The upper surface of the headgung is spaced apart from the center in the radial direction at equal intervals to form guide protrusions, and between the guide protrusions, two protrusions with a "L"-shaped cross section are formed between the guide protrusions, and pressurized therebetween. It is configured to guide the linear motion of the member.

The cap of the operation unit is formed on the head, and a boss is formed to engage with guide protrusions passing through the long holes of each of the pressing members on both sides, a hole is formed in the center, and the cam plate has a guide ring provided inside the hole of the cap It is provided rotatably inside the member.

The lid for the pressure stone pot according to the present invention has a simplified structure in which the cam plate rotates according to the rotation of the handle, and the protrusion is engaged with the cam hole of the cam plate, and the pressing member is moved to combine or release the rim portions of the cap and the stone pot. Costs can be reduced, the risk of failure is minimized, and ease of use is improved because the operation is simple and reliable.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings showing embodiments of the present invention.

1 to 3, the lid for the pressure stone pot according to the present invention has a lower end edge disposed on the edge of the stone pot (1) to cover the stone pot (2), and the edge of the stone pot (1) and the cover (2) are in close contact Two pressing members (3) arranged in a radial direction on the lid so as to be movable in the radial direction inward and outward between the pressing position for releasing and releasing from the close contact, and the pressing members (3) engaged with the pressing members to hold the pressing members. It includes an operation unit (4) for displacing with respect to.

The rim portion 21 is disposed on the rim of the stone pot 1, and guide protrusions 22 spaced from the center at equal intervals in the diametrical direction are formed on the upper surface of the headgung 2, and the guide protrusions ( 22) between the two protrusions 23 with a cross-section of a “L”-shaped spaced apart are formed therebetween to guide the linear motion of the pressing member 3 as will be described later between them.

Each of the pressing members 3 has a “L” shape in cross section, and a holder part ( 31) is formed at the outer end, and a long hole 32 is formed in the horizontal portion 33 so that the guide protrusion 22 of the headgung 2 is fitted and guided to move in and out in the radial direction, and at the inner end A protrusion 34 protruding upward is formed.

In each of the pressing members 3, the guide protrusion 22 formed on the upper surface of the hood 2 is inserted into the long hole 32 of the horizontal part 33, and the holder part 31 of the outer end is the edge part of the hood 2 The horizontal portions 33 on the upper surface of the headgung to be fitted in the (21) are arranged at positions opposite to each other in the diametric direction.

The manipulation unit 4 is formed on the head, and a boss 411 is formed to engage the guide protrusions 22 penetrating the long holes 32 of each of the pressing members 3 on both sides, and a hole 413 is formed in the center. The formed cap 41, the guide ring member 42 provided inside the hole 413 of the cap, and the protrusion ( The cam plate 43 engages with 34 to displace the pressing members 3 to the pressing position and the releasing position, and the cam plate 43 rotates the cam plate 43 to manipulate the pressing member 3 into the pressing position and the releasing position. ) and a handle 44 coupled with a screw.

In the cam plate 43, cam holes 431 and 431' having one side curved closer to the center are symmetrically formed around the center of rotation, and the cam holes 431 and 431' have the horizontal positions of the pressing members 3 respectively. The protrusions 34 formed on the part penetrate and the protrusions are displaced by the cam holes according to the rotation of the cam plate, and the pressing members 3 are displaced to the pressing position and the releasing position to open and close the cap.
