Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a lid device for a cooker that covers the opening of a pot with a porridge lid for cooking porridge.

(b) Prior Art Most cooking appliances with a pot have a lid that covers the opening of the pot. One of the cooking methods that requires the most care when using a cooker with a lid like this is ``rice porridge cooking,'' which uses a large amount of water. In other words, when cooking rice porridge, when the food to be cooked reaches a boiling state, the steam and slime generated in the pot push up the lid and forcefully flow out to the outside, causing overflow. It is necessary to lift the container and release the steam and slime to the outside air.

In order to eliminate the need for such troublesome operations,
As shown in Publication No. 57-38108, a gap was created in advance at the contact area between the lid and the pot, and steam and sticky liquid were released from this gap, but when the boiling state reached its peak, steam spouted out from the gap. Because of this, there was a risk of burns if the product hit the fingers.

(c) Problems to be solved by the invention The invention prevents porridge from overflowing when cooking, and also prevents steam from flowing out from the periphery of the porridge lid.

(d) Means for solving the problem The present invention consists of a frame, a frame cover fixed to the frame and formed with a ring-shaped exposure groove, a pot provided with a flange, and a plurality of holes extending downward. The rice porridge lid is comprised of a protruding wall placed on the flange and a guide wall provided outside the protruding wall with an edge spaced apart from the pot and facing the condensation groove.

(E) Effect In the present invention, the steam generated in the pot flows out through the holes to suppress the increase in pressure in the pot, and the dew adhering to the inner wall of the porridge lid falls into the pot along the ridged wall. Furthermore, even if a gap is created between the protruding wall and the flange of the pot, and steam or sticky liquid flows out from this gap, the steam will be weakened by the guide wall and will flow along the guide wall. It falls into the ditch.

(f) Examples Examples of the present invention will be explained based on the drawings. 1 is a frame integrally molded into a cylindrical shape from synthetic resin; 2
is a storage case stored and fixed inside the frame,
3 is a bottomed cylindrical pot stored in the storage case 2; 4 is a heat insulating material interposed between the frame 1 and the storage case 2; 5 is a disk-shaped heater fixed to the inner bottom of the storage case 2; , 6 is a back plate fixed to the lower part of the frame 1 and covers the outer bottom surface of the storage case 2, and 7 is a temperature protector tightly fixed to the side wall of the storage case 2 by a mounting bracket 8.

Reference numeral 9 denotes a ring-shaped frame cover made of synthetic resin that fits and fixes the upper peripheral edges of the frame 1 and the storage case 2, and has a ring-shaped exposed groove 10 formed on the upper surface and a bearing that protrudes outward on one side. The body 11 is integrally molded. As shown in FIGS. 2 and 3, this bearing body 11 is provided with a U-shaped insertion groove 12 that opens horizontally toward the center of the pot 3, and a guide hole 13 that communicates with the insertion groove and opens vertically. , furthermore, the exposure groove 10 is provided at a position closer to the center of the pot 3 than the guide hole.
A dew drop hole 14 that is open in the vertical direction and communicates with the dew hole 14 is provided. 15 is a locking stepped portion 16 at the lower part of both side walls,
16, a cavity 17 on the inside, and a locking piece 18 on the top.
The locking piece 18 is inserted into the guide hole 13 to project the operating portion 19 to the outside of the bearing body 11 using a locking body integrally molded with each of the operating portions 19 projecting outward from the rear side wall. Reference numeral 20 denotes a planar-shaped support base having a through hole 21, and is fixed to the lower part of the bearing body 11 with the hooking body 15 installed therein by screws 22, 22. Reference numeral 23 denotes a spring housed in the cavity 17, which biases the locking piece 18 so that it always protrudes into the insertion groove 12. Reference numeral 24 denotes a dew receptor that engages with the support base and is detachable.

25 is an outer lid 28 consisting of an upper plate 26 and a lower plate 27.
and a heat-insulating lid 2 removably attached to the bottom of the outer lid.
9 and an inner lid 30, a horizontally long shaft 31 provided on one side is fitted into the insertion groove 12 of the bearing body 11 to make it rotatable and detachable, and a chain gun is provided on the other side. A button 32 is provided so that it can be hung on a stopper (not shown) provided on the frame cover 9.
The bearing body 11, the locking body 15, and the shaft rod 31 constitute a locking device 33. Reference numeral 34 denotes an inverted U-shaped handle provided above the lid 25, and is integrally fixed to the lid 25 by screws 35 that fix the upper plate 26 and the lower plate 27. 36 is a heat insulating material interposed between the upper plate 26 and the lower plate 27; 37 is the lower plate 27;
A support pin protruding downward from the center of the 3
Reference numerals 8 and 39 denote pushings fixed to the central portions of the heat-retaining lid 29 and the inner lid 30, and 40 a plurality of holes 41, 41... on the upper surface, a knob 42, and a pusher extending downward to the lower part of the periphery outside the holes. A vertical ring-shaped protruding wall 43 and a ring-shaped guide wall 4 that is outside the protruding wall and extends downward from the lower end of the protruding wall.
This is a rice porridge lid with 4 parts.

Next, we will discuss the operation. First, when attaching the lid body 25, push down the operating part 19 against the spring 23 as shown by the arrow in FIG. state. In this state, the shaft rod 31 is fitted into the insertion groove 12, the operating part 19 is released from the depression, and the locking piece 18 is pushed into the insertion groove 12 by the spring 23, and the peripheral side wall of the shaft rod 31 is inserted into the insertion groove 12. It is surrounded by the inner wall surface and the locking piece 18 to prevent it from coming off. In this way, the lid body 25 is pivotally supported on the pot side, but when the lid is to be closed, it is rotated and the chain gun button 32 is hooked to the stopper of the frame cover 9.

Further, when removing the lid body 25, the operating portion 19 is pushed down and the shaft rod 31 is removed from the insertion groove 12 in the same manner as in the case of attachment described above.

In this way, the removed lid body 25 can be washed with water, and the vicinity of the bearing body 11 can be easily wiped of dew and the like.

Thus, when the lid body 25 is removed, the sixth
As shown in the figure, attach the lower end of the protruding wall 43 of the porridge lid 40 to the pot 3.
Place the edge of the guide wall 44 on the flange 3b of the pot 3.
The heater 5 is placed facing the dew receiving groove 10 at a distance from the heater 5.
When electricity is applied to the pot, the steam generated in the pot flows through the holes 41 and 4.
1...It flows out more and suppresses the rise in pressure inside the pot. The dew attached to the inner wall of the porridge lid 40 is removed from the protruding wall 4.
3 to the flange 3b, and most of it is returned to the pot, but some remains. In such a state, for some reason, for example, a part of the hole 41 is blocked by bubbles in the sticky liquid, the internal pressure rises slightly, and the porridge lid 40 rises, causing the ridge wall 43 and flange 3b to When a gap is created between them, the steam flowing out from this gap flows into the outflow path formed by the space between the pot 3 and the guide wall 44, and then hits the inner wall of the guide wall 44 and its momentum is weakened. The waste on the flange 3b hits the guide wall 44 and falls, and accumulates in the dew receiving groove 10.

(G) Effects of the invention In this invention, the porridge lid is provided with multiple holes through which the steam inside the pot flows out, so the pressure inside the pot does not increase and overflow is eliminated. In addition, the porridge lid has a ring-shaped protruding wall that rests on the flange of the pot.
In particular, dew adhering to the inner wall of the porridge lid near the hole does not fall into the pot along the protruding wall and flow out of the hole along with the steam. Furthermore, even if steam or goo flows out from the protruding wall for some reason, the guide wall outside the protruding wall is spaced apart from the pot, so a wide outflow path is ensured, and the guide wall The outflow speed decreases when the water hits the guide wall, and it is collected in the exposed groove along the guide wall, so there is no danger of burns.
