Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pot with a lid for deep-frying and stir-frying, which is used for tempura, fried dishes, and the like.

Generally speaking, it is sufficient to cover the frying pan as a means to prevent oil from springing up while frying, and to prevent the oil that is often generated from catching fire and causing a fire.
It has the following drawbacks:

In other words, closing the lid reliably prevents oil springs and the risk of fire due to lack of oxygen inside the pot, but if the lid opening is opaque, it is impossible to observe the inside of the pot. Therefore, it has no choice but to be transparent.

However, since a large amount of water vapor is generated from inside the pot, the transparent body of the cut corner quickly fogs up, impairing the internal observation function and making it impractical. Therefore, in the present invention, a method is adopted to prevent the transparent lid from fogging. In order to perform the internal observation function, a blind mechanism is provided to quickly dissipate the generated gas to the outside, and the opening area of the lid plate that covers the pot opening is made as equal as possible to the opening area of the pot opening. This is a conventional frying pot that can be opened and closed using only a part of the cover that covers almost the entire opening of the pot as a lid piece, making it even more convenient and also functioning as a frying pan such as a frying pan. be.

In recent years, with the development of dietary habits, stir-fried dishes have increased, and it is common to cover these dishes to prevent oil springs, but it is still impossible to observe the inside, and it is difficult to cook for long periods of time. In the past, it has been pointed out that when cooking stir-fried foods, the steam generated in the pot tends to overwhelm, resulting in a dish that resembles steamed food.

However, in the device of the present invention, since almost the entire opening area of the pot can be opened as described above, it is possible to adapt it to a stir-fry pot. By also incorporating a lid plate weight canceling mechanism that does not cause any resistance and is extremely convenient to handle, the present invention provides an extremely innovative pot with a lid for frying and stir-frying on the market. This has made it possible to provide this service to the public.

The present invention is based on the patent application No. 52-6606 filed by the same applicant.
This invention has been developed to further simplify the content of invention No. 2.

Embodiments of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 indicates a frying and stir-frying cooking pot body having an inverted trapezoidal shape with a relatively shallow bottom, and a lid that opens and closes using one end as a fulcrum at its opening. The plate 3 is fixed so as to be detachable (examples thereof will be described later) or to be operable to open and close.

A pair of swinging arm pieces 4, 4' are protruded from one end of the cover plate 3 made of a heat-resistant transparent material such as thick glass, which covers almost the entire surface of the opening of the pot body 1, and is rotatable on the pot side shaft bearing. A lid plate weight canceling mechanism part 5 is attached that can support the lid plate 3 and cancel the weight of the lid plate 3 that is loaded on the arm piece, and can stand still at any opening angle.

The other end of the lid plate 3 is provided with a hook portion on the side of the pot 1, or provided with an appropriate shape on the inner wall surface on the chain side or a part of the lid body so that the lower limit of operation is the horizontal state in which the lid plate itself performs the closing action. A stopper (not shown) may be provided with a one-step portion (not shown) to prevent the cover plate from being inserted more than necessary.

In this embodiment, as will be described later, the guide notch 13 of the collar 2,
The movable range is regulated by the correlation between 13' and the swinging arm pieces 4, 4'.

The correspondence relationship between the pot body 1 and the lid plate 3 is as shown in FIGS. 1 to 3. The lid plate 3 is loosely fitted to the upper edge of the opening of the pot body 1, and gases such as steam and oil smoke rising from the inside of the pot are prevented. Ventilation gap S to quickly escape from the system by utilizing the possibility of bending.
At the same time, the oil splashes generated from inside the pot are kept in the system by utilizing their straight-line propagation properties.

The lid plate self-weight canceling mechanism 5 is constructed, for example, as shown in FIG. This is intended to balance the weight of the thick glass lid plate 3.

Although the spring force used here may be conventionally known technical means such as using the expansion/contraction strain force of a normal tension spring, etc.
The present invention utilizes the twisting and rotational elasticity of the winding spring.

That is, the reduced diameter portions 8, 8' of the operating shaft 7 are rotated by bearing the reduced diameter portions 8, 8' of the operating shaft 7 on the L-shaped wheel bearing pieces 6, 6' which are fixed by screws or welding to the flange 2 that protrudes from a part of the opening edge of the pot body 1. In order to integrally move the base end portions of the swinging arm pieces 4, 4', which attach the upper end of the transparent cover plate 3 made of thick glass to the rectangular shaft portion 9.9′ which is freely movable and extends into the reduced diameter portion. At the same time, the outer ends of the wound springs 11 and 11' are wound around the left and right sides of the operating shaft 7, respectively, and the inner ends of the springs 10 and 10' are fixed to the shafts.
, 6', both swinging arm pieces 4, 4' are made to protrude outward from guide notches 13, 13' in the collar 2, and the opening/closing angle is regulated by the notches. When fixing the base end of the swinging arm piece 4, 4' to the rectangular shaft portions 9, 9' of the operating shaft 7, the operating shaft 7 is twisted and rotated in advance. The coiled spring 11.11' is returned to the coiled spring 11.11' to store its rotational elasticity and is then individually determined. By selecting this, the return rotation elasticity of 11, 11' and the own weight of the cover plate 3 can be appropriately balanced. For example, when closing the cover, the closer the cover falls to the horizontal position, the more the gravity of the cover increases, but at the same time the spring The spring force is adjusted so that the return rotational elasticity also increases at the same rate as the gradual change in . .

For this reason, when opening and closing the lid plate 3, the gravity of the lid plate 3 can be made extremely light.
, 13', it is possible to stand still at any position within the opening/closing permissible angle regulated by .

Reference numeral 14 denotes a handle for opening/closing operation provided protruding from the tip of the lid plate 3.

Figure 5 shows the 1. 2. Figure 3 shows an embodiment in which the lid plate self-weight canceling mechanism 5 is fixed and supported on the flange 2 of the pot body 1, whereas the flange 2, which is the bearing part of the lid plate 3, is attached to the flange 2 of the pot body 1. A U that is separable from the pot body 1 and protrudes from the outside of the pot body 1.
A female protrusion 16 corresponding to the groove spring material 15 is formed on the separation flange 2' to provide convenience in cleaning. For example, as shown in FIG. 9, the connected state is such that the hanging piece 17 of the female projection 16 is fitted into the U-groove, and a pair of guide hem pieces 18 are formed at both ends of the hanging piece 17, respectively, protruding in corresponding directions. It is preferable to configure it so that 18' is exposed to the outside.

The oil draining vat 19, which is removably equipped with a net 20 for draining the oil on which the following dishes are placed, is integrated with the main body 1 of the application pot 1 in a monadic shape as shown in Figure 6, and then stored and stored. One of the clever applications of the present invention is to make it easy to use.

The present invention has the above-mentioned configuration, and the lid plate 3 in the state shown in FIG. 1 is lifted by its handle 14 to open the pot body 1. cover plate 3
The self-weight canceling mechanism 5 acts, allowing the user to open and close the device in a state close to zero gravity, and to allow the device to stand still at any opening angle, for example, when cooking fried foods.
If you want to prevent oil splashes as much as possible, even if you want to turn the food inside the pot over, you can simply leave a small gap between the pot and the lid by inserting a pair of chopsticks, and the lid plate will allow you to turn the food over. The presence of the transparent lid, which is the main part of the present invention, is even more effective due to its ease of operation, since it is possible to handle the lid freely without giving any sense of resistance.

In addition, since the lid plate 3 is loosely fitted with only a ventilation gap S left at the tin opening, the oil droplets generated from inside the pot will be removed as shown by the arrow in Figure 2-3. Since it is linear in nature, for example, as long as the oil level (Fig. 7) in a frying pan and the bottom surface (Fig. 8) in a stir-fry pan are both smaller than the inner diameter of the gap S, the gap will remain constant. The shape and cone shown in Figures 7 and 8 are also suitable for the present invention because there is almost no fear of them splashing outward from S, and it is possible to perform a blind function that allows only gases such as water vapor and oil smoke to be discharged. It is clear that it belongs to the range.

In addition, in the device of the present invention, gas is constantly generated from inside the pot during cooking, and air from outside does not flow into the pot, so when the lid is closed, the interior is almost oxygen-deficient, so the oil temperature will rise. There is no danger of the pot catching fire, and even if you happen to get sick while cooking and have to leave the site for a long time due to an emergency, as long as the pot is covered, there is no risk of the pot catching fire.
This invention is effective in preventing the causes of fires during deep-fried food cooking, and the present invention solves at once the three major problems of oil springs and fire prevention in deep-fried and stir-fried food dishes, which had previously posed major problems. This is an extremely excellent invention.

In this embodiment, the combined pot body 1 and lid body 3 are formed into a rectangular shape, but the gist of the present invention does not change even if the shape is round, polygonal, or the like.
