This part, which is fixed to the housing, is preferably an appendage 9 or a housing section 10, which is molded or integrally molded on the housing side, in particular on the housing bottom side. In the case of an appendage 9, the latter preferably projects freely vertically downwards beyond the housing bottom surface, which is oriented downwards. In an alternative embodiment, the appendage 9 is connected to a weighing beam of a weighing device, preferably in a rigid manner, preferably above the housing bottom 8, with said weighing beam, in turn, engaging on the other end of the housing, in particular on the housing bottom side.
(21) The appendage 9 or the housing section 10, respectively, is embodied as rigid part, more preferably together with the housing bottom 8 as a result of a one-piece, material-homogenous embodiment. Accordingly, the appendage 9 or the housing section 10 can be a hard plastic or a metal body, which is more preferably embodied in a rotationally symmetric manner with reference to a vertical axis x, which penetrates the appendage 9 or the housing section 10, respectively, centrally. In addition to the one-piece embodiment, provision is furthermore made as an alternative for an appendage 9 or a housing section 10, which can be fixed, for example screwed to the housing bottom 8 on the bottom side.
(22) In the first exemplary embodiments illustrated in particular in
(23) The appendage 9 is substantially formed as rotationally symmetrical hollow body, comprising a circumferential appendage wall 13. A base 15 is inserted in one piece and preferably in a material-homogenous manner with the appendage wall 13 into the tube opening 14, which is comprised by the appendage wall 13, at a vertical distance to the outer edge of the appendage wall 13, which is free vertically downwards.
(24) A tube section 16, which is arranged concentrically to the vertical axis x and the front surface of which, which is oriented vertically downwards, projects beyond the horizontal plane, which is defined by the free outer edge of the appendage wall 13, which is oriented downwards, is integrally molded to the base 15 on the bottom side, thus oriented vertically downwards. A vertical distance c between the front surface of the tube section 16, which extends in a horizontal plane, and the front outer edge of the appendage wall 13 preferably corresponds to one-half to one-tenth, more preferably approximately one-third of the outer diameter d of the appendage wall 13 in the area of the base 15.

It has a shell bottom 19, which is more preferably shaped in a circular disk-like manner, and a circumferential, preferably cylindrical shell wall 20. The vertical height of the shell wall 20 preferably corresponds substantially to the vertical extension measure of the aperture 17 in the appendage 9.
(28) The inner diameter f of the shell section 18 preferably corresponds to 1.1-times to 1.4-times the outer diameter d of the appendage wall 13, whereby an annular gap 21 appears circumferentially between the appendage wall 13 and the shell wall 20 in a basic orientation as illustrated in
(29) Starting at the surface of the shell bottom 19 on the inner side of the shell, a journal 22, which preferably has a circular disk-shaped and/or cylindrical cross section, grows. Said journal is preferably arranged centrally to the shell section 18 and is molded in one piece, in a material-homogenous manner with the shell section 18. The diameter g is hereby chosen so as to be smaller than the inner diameter h of the aperture 17 on the appendage side, wherein, with its front surface, which is oriented vertically upwards, the journal 22 projects beyond the plane of the appendage base 15, which is oriented upwards, passing through the aperture 17. A concentric arrangement of appendage 9 and shell section 18 results in a circumferential gap, the radial measure of which is preferably equal to or larger than the radial measure of the annular gap 21, between the journal 22 and the wall of the aperture 17.
(30) The shell section 18 is mounted to the appendage 9 in a positive manner. For this purpose, provision is made for an overlap disk 23, which is centrally permeated by the journal 22 and which preferably rests against the surface of the base 15, which is oriented upwards.

(46) As a result of the arrangement in particular of the soft part 26 as well as of the preferred direct fastening of the soft part 26 with the shell bottom 19, more preferably also with the foot part 12, the stability of the kitchen appliance 1 as a whole is improved, wherein the rubber-like foot part 12 prevents that the soft part 26 is damaged by friction relative to the table surface 7, for example in response to shifting the kitchen appliance 1.
(47) The surface of the foot part 12, which is oriented downwards, hereby forms the base 10 for interaction with the table surface 7, for example.
(48)
(49) With its surface, which faces away from the foot part 12, the soft part 26 is connected directly and to a housing section 10 of the kitchen appliance 1. Preferably, an adhesive connection is used here.
(50) Preferably facing the soft part 26, the housing section 10 has a flat surface, in particular for a holohedral adhesion to the soft part 26.
(51) In a preferred embodiment, the housing section 10 is part of the housing bottom 8, hereby preferably extends below a bottom plane, which is generally oriented downwards. According to the afore-described exemplary embodiment, the housing section 10 as well as the appendage 9 can also extend above the bottom plane and can hereby be a part of a weighing beam, for example.
