Further, such cooking device can also be divided into several cooking devices such as cooking device with low operating head, cooking device with middleoperating head and cooking device with high head, and appropriate cooking device can be chosen depending on the foods to be cooked.
[3] Also, most of such cooking devices are provided with a step portion at their periphery to prevent the overflow of the rice water or soup and the pot stew, and a cover is placed and used on the upper step portion of the cooking device.
[4] The material for manufacturing such cooking device can be selected from an aluminum, which is good in heat conductivity and has rust resistant property to make it convenient to use, a steel plate which is good in heat conductivity and good in heat insulation property, also it can be made of an enamel with the white soil coated so that it can boil the foods for a long time.
[5] As described above, such cooking device is generally constructed to increase the heat transmission efficiency and heat insulation property by using various materials, and in such a cooking device, a gap produced between the cooking device and the cover is decreased to thereby maintain the temperature in the device, resulting in the increase of the heating efficiency.
[6] However, the cooking device and the cover for it cannot be closed completely because the inside air will be expanded due to the inside heat and the water in the device heated to be vaporized as a steam.
[7] Accordingly, as shown in FIG. 1, al least one venting hole 111 is formed at the cover 110 for the cooking device, and inside steam and the expanded air can be discharged through the venting hole 111 to thereby maintain the closed state between the cover and the cooking device 1.
[8] In this instance, as it is difficult to discharge the whole steam and the expanded air through the venting hole 111, the saturated steam and the expanded air are discharged through the gap produced between the cover 110 and the support portion 101 formed as step shape of the cooking device 100. However, as shown in FlG. 2, in such an engagement structure, the inside moisture is vaporized and rises, then descends along the inclined surface of the cover 110 to thereby form water films, resulting in the closing of an engagement portion. Accordingly, the inside air and the steam cannot be discharged smoothly.
[9] As a result, the cover 110 of the cooking device is floated up and down by the push of the pressure of the expanded air and the steam, so that it is necessary to clean the cooking device 100, the cover 110, and the other portions of the cooking device more than they are required, because the soup and the pot stew have been splashed on those portions. Therefore, the cover 110 has been positioned slant on the support portion of the cooking device so as to reduce the excessive floating of the devices.
[10] Further, as the use of the cover is not stable, the cover 110 has been often separated from the cooking device to thereby increase the heat loss of the cooking device 100, resulting in the extension of the cooking time and increase of the energy consumption.
