    • A knife may act as top or bottom knife of the cutting device of an electric razor or beard trimmer that consists of a top and a bottom knife. In its cutting area designed as a smooth sliding surface on a comb strip (6), the knife (1) has a plurality of teeth (7, 8) with intermediate slits (9) whose edges are designed as cutting edges (31). The knife (1) further has one or several walls angled in relation to the cutting area. The cutting area (30) of the knife (1) consists of a blade (2, 35) made of hardened steel sheet. The teeth (6, 7, 34) of the blade (2, 35) are produced by etching. The walls (3, 4, 46) of the knife (1, 29) are produced by welding one or several shaped steel sheet sections on the blade (2, 35). Welding is carried out in such a way that the resulting temperature increase of the blade (2, 35) be so reduced that the hardened steel sheet (2, 3) is not disadvantageously deformed, nor loses its hardness or wear-resistance. A particularly sharp and durable knife (1) is thus produced, which in addition can be produced in a particularly simple and economic manner.
    • 本发明涉及一种接受电动剃须刀,电动修剪器胡须或者上部或下部刀的功能的上和下刀刃切割机的面板刀。 所述的叶片(1)具有在上梳条(6)其构成为平坦的滑动面切割部上的多个齿(7,8)与中间槽(9)和在它们的边缘具有形成切削刃(31)。 对刀(1)被布置成抵靠切削区域成角度的壁部分的一个或多个。 刀(1)的切断部(30)由片(2,35)由硬化钢板,其特征在于,所述叶片(2,35)的齿(6,7,34)通过蚀刻产生的。 刀(1,29)的壁部分(3,4,46)由一个焊接或多个成形金属板部的与叶片(2,35)形成。 焊接进行,使得在所述叶片(2,35)的温度所得到的增加失败如此之低,硬化金属片(2,35)不干扰变形经历仍基本上丧失其硬度和耐磨性。 这导致特别锋利耐用叶片(1),其可以被更容易和kostengüngstig制造到另一个。

    • The invention concerns a kitchen appliance comprising an electric drive motor (9) which is disposed in a housing (1, 3, 4) substantially perpendicular to the surface on which said appliance stands. The drive motor (9) is surrounded by a housing part (3), ventilation apertures (13, 14) being formed in the housing (1, 3, 4). The drive motor (9) is not provided with fan wheels. Viewed in the longitudinal extension (X) of the drive motor (9), the ventilation apertures (13, 14) are disposed substantially in the region of the opposite ends of the housing part (3). The ventilation aperture (14) through which the hot air (18) is discharged is disposed above the drive motor (9). As a result, even without fan wheels, an air flow is produced by convection from the air inlet apertures (13) to the air outlet apertures (14), so rendering the appliance more economical and quieter yet providing adequate cooling of the drive motor (9).
    • 本发明涉及一种食品加工机,其被布置成与大致垂直于食物机器的表面在壳体(1,3,4),电驱动马达(9)。 所述驱动马达(9)由一个壳体件(3),其中,在所述壳体包围(1,3,4)通风口(13,14)形成。 所述驱动马达(9)是lüfterradfrei。 在所述驱动马达(9)看出的纵向延伸(X)的通风开口(13,14)在所述壳体部件的相对端部的区域基本上布置(3)。 该排气口(14)从所述热空气(18)的驱动马达(9)的上方形成射出。 以这种方式,由于空气出口的空气流,以对流从空气入口(13)(14),即使没有风扇轮实现的,从而降低了成本,该装置使得一个低的,但足以冷却所述驱动马达(9)。
