Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a steam exhaust device for a cooker having a steam cylinder for releasing steam above the main body of the cooker.

Structure of conventional example and its problems As shown in Fig. 1, in the conventional steam exhaust device for a cooking device, a steam cylinder 1 is caulked and fixed to a heat sink 2 which is a part of the lid, and a steam cylinder 1 is attached to the top surface of the steam cylinder 1. The structure was provided with a steam port 3 for discharging steam.

However, according to the above configuration, when steam containing viscous bubbles is discharged, there is a problem that droplets when the bubbles are crushed by the steam fly out of the steam port 3 and stain the area around the cooker. . Particularly in recent years, cooking appliances have become more diverse, such as those that apply pressure,
Many of these droplets are of high wattage, and the amount of droplets is increasing, making the problem more serious.

Purpose of the invention The present invention solves these conventional problems,
The present invention aims to improve the splash prevention performance and provide a steam exhaust device for a cooker that has splash prevention performance that is compatible with pressure type cookers and high-wattage cooking.

Composition of the Invention In the steam exhaust device for a cooking device of the present invention, a splash prevention plate is disposed with a gap in a steam cylinder having an opening at the top, and the splash prevention plate is placed at a position that does not face the opening of the steam cylinder. This structure creates an obstruction in the flow path of steam inside the steam cylinder during cooking, and prevents droplets from reaching the outside of the cooking appliance.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In Figures 2 to 5, 4 is the cooking device body, 5
is a heat source for cooking and heating; 6 is a pot placed on the heat source 5 for storing food; 7 is an outer lid; 8 is an inner lid that covers the pot 6;
Reference numeral 9 denotes a steam cylinder support plate arranged on the lower surface of the outer lid 7, to which a steam cylinder 10 and a splash prevention plate 11 are attached by caulking.

The steam cylinder 10 is provided with an opening 10a on the top surface, and the top surface of the splash prevention plate 11, which is caulked and fixed inside the steam cylinder 10, is provided with an opening at a position that does not face the opening 10a of the steam cylinder 10. A portion 11a is provided.

To explain the operation in the above configuration, during cooking, there is always a flow of steam from the bottom to the top in the steam cylinder 10, and the crushed bubbles on the inner lid 8,
The water becomes droplets and is carried along with the steam toward the steam cylinder 10.

Next, the state of generation of droplets will be explained in comparison with a conventional example.

FIG. 6A shows the flow of steam in the conventional example, and the bubbles that form on the inner lid, which form water droplets, fly out of the cooking device without any obstruction and become splashes.

However, in the embodiment of the present invention, as shown in FIG. 6B, there is an obstacle in the steam flow path, that is, the splash prevention plate 1.
1, the bubbles that become water droplets collide with the wall of the splash prevention plate 11, and the water droplet bubbles that pass through the opening 11a of the splash prevention plate 11 collide with the wall of the steam cylinder 10, and are exposed to the outside. I don't go out.

In this way, by providing a barrier in the middle of the upward flow of steam, only the bubbles in the form of water droplets can hit the wall and fall off, thereby preventing the generation of splashes. This effect can be achieved by providing a gap between the steam cylinder 10 and the splash prevention plate 11, and by creating a structure that does not obediently allow the flow of steam to escape.

Effects of the Invention As described above, according to the present invention, there is provided a steam cylinder having an opening on the top surface for discharging steam generated in the cooking device, and a steam cylinder arranged in the steam cylinder so as to face the opening. Since the top surface of this splash prevention plate has an opening at a position that does not face the opening of the steam cylinder, water droplets that flow into the steam cylinder first pass through the splash prevention plate. The water droplet-shaped bubbles that hit the wall and passed through the opening of the splash prevention plate will then hit the steam cylinder wall, and as a result, the water droplet-shaped bubbles will be prevented from coming out of the steam cylinder. This can be reliably prevented, and since the openings are provided on the top surface of the steam cylinder and the top surface of the splash prevention plate, it is possible to obtain a compact structure.

In addition, because the splash prevention plate has more openings than the openings of the steam cylinder, the steam generated in the cooker flows at a slow flow rate into the steam cylinder above the splash prevention plate, and inside the steam cylinder. After sufficient dew condensation occurs, it is released outside the steam cylinder, and the moisture content of the steam discharged outside the machine can be kept low.
