    • A non-open fire type cooking burner capable of exhibiting endurance, workability and safety. Heat combustion or exhaust gas produced by combustion in a burner body are guided to a heat exchanger made of metal and discharged through an exhaust pipe to an exterior of a room, respectively. The heat is then radiated to a ceramic plate arranged above the heat exchanger for cooking. An air shifter provided with an air-direction change-over damper is arranged so as to change over flowing of air, to thereby permit the cooking burner to be applied to space heating as well as cooking.
    • 能够显示耐久性,可加工性和安全性的非开放型火焰烹饪燃烧器。 在燃烧器体内由燃烧产生的热燃烧或排气被引导到由金属制成的热交换器,并且分别通过排气管排出到室外。 然后将热辐射到布置在热交换器上方的陶瓷板进行烹饪。 设置有空气方向转换阻尼器的空气移动器被布置成改变空气的流动,从而允许烹饪燃烧器应用于空间加热以及烹饪。

    • The present invention relates to a benzene detecting element capable of detecting benzene selectively and highly sensitively, and a preparation process thereof. The benzene detecting element of the present invention is a mesoporous silicate for detecting benzene selectively and highly sensitively in atmospheric air, and the detecting element has a nanosized fine pore having a highly ordered periodic fine pore structure, and the wall of the nanosized fine pore has a sub-nanosized fine pore. The nanosized fine pore has a pore size of from 0.15 nm to 50 nm in radius, the sub-nanosized fine pore has a pore size of from 0.05 to 0.5 nm in radius, and at least the sub-nanosized fine pore among the fine pores is modified with an organosilicon functional group having a phenyl group, or a silanol group. The present invention also relates to a preparation process of the detecting element.

    • The present invention relates to a structure in which an unburnt gas can be prevented from being diffused into a room while suppressing the generation of the unburnt gas during the extinction operation of a pot type oil burner. During the extinction operation, first of all, the supply of a fuel from fuel feeding means (35) to a pot (15) is stopped and conduction to an electric heater (31) is started. The rotation of each of a combustion fan (23) and a convection fan (11) is carried out continuously. While a second timer (67) counts a second time period, the convection fan (11) is rotated at a high speed. After the second time period is ended, the rotation of the convection fan (11) is switched from high speed rotation into low speed rotation. The low speed rotation is carried out continuously for a third time period counted by a third timer. After the third time period is ended, the rotation of the convection fan (11) is returned from the low speed rotation to the high speed rotation. During the low speed rotation, an unburnt gas discharged from an air outlet (3) of a frame body (1) to the outside is raised to a ceiling portion with a natural convection so that the diffusion of the unburnt gas can be suppressed.
    • 本发明涉及一种结构,其中可以防止在锅式油燃烧器的灭火操作期间抑制未燃烧气体的产生而扩散到房间中的未燃烧气体。 在灭火操作期间,首先停止从燃料供给装置(35)向罐(15)供给燃料并且向电加热器(31)传导。 燃烧风扇(23)和对流风扇(11)各自的旋转被连续地进行。 当第二计时器(67)计数第二时间段时,对流风扇(11)以高速旋转。 在第二时间段结束之后,对流风扇(11)的旋转从高速旋转切换到低速旋转。 低速旋转连续进行由第三定时器计数的第三时间段。 在第三时间段结束之后,对流风扇(11)的旋转从低速旋转返回到高速旋转。 在低速旋转中,从框体(1)的出风口(3)向外部排出的未燃烧气体以自然对流被升温到顶部,从而能够抑制未燃烧气体的扩散。
