Problems solved by technology

This reduces the weight of the housing, but also impairs the cooling of the electric drive due to the poor thermal conductivity of the plastic
Depending on the type and size of the plastic this measure is also accompanied by a reduction in strength

Embodiment Construction

[0035] exist figure 1 The housing 1 shown in is used to accommodate and position an electric drive, in this embodiment for an electric household appliance. The housing 1 is formed by stamping from a relatively thin metal plate, especially a steel plate with a thickness of less than 1.0 mm. In this embodiment, the plate thickness of 0.8 mm is sufficient to withstand the static and dynamic loads generated when the household appliance is in operation.

[0036] The bowl-shaped housing 1 is composed of a radial wall 2 and an upper end wall 3 and is designed to be open at the bottom. The positional descriptions here relate to customary, but not mandatory, installation positions of the housing 1 .

[0037] Transversely across the front wall 3 and through its center 4 , first channel-shaped embossments 5 extend through their mutually opposite end regions as far as the circumference 6 of the front wall. The rectilinear punching marks 5 have a U-shaped cross section and are curved ou...

Abstract

The invention relates to a housing (1) for the drive of an electrical device, particularly a household appliance, comprising a radial wall (2) and a front wall (3) having one or more embossments. According to the invention, at least one first embossment (5) in the front wall is designed like a channel and extends between areas of the circumference (6) of the front wall (3) opposite each other. The first channel-like embossment (5) preferably opens into recesses (7) located opposite each other, through which the brush arrangement (B) of the electrical drive can be inserted into the channel-like embossment (5) and secured. A second channel-like embossment (12) preferably extends perpendicular to the first embossment (5), meeting the first embossment in the center (4) of the front wall (3) and a dome-like embossment (13) located there for receiving a bearing arrangement. The invention further relates to a housing (1) for the drive of an electrical device, wherein areas of the radial wall (2), the first front wall (3), and / or a second front wall (26) have honeycomb-shaped embossments (27) in the form of multidimensional arch structures. Savings in materials can be advantageously achieved by the invention. The cooling power can also be increased and noise generation reduced.

Description

technical field [0001] The invention relates to a housing for a drive unit of an electrical device, in particular a domestic appliance, having radial walls and at least one first end wall, which is provided with one or more punched indentations. Background technique [0002] A housing of the above-mentioned type is known from the laid-open document DE 197 17 594 A1 for accommodating a rotor of an electric drive for a domestic appliance. The bowl-shaped housing, stamped from sheet steel, has a cylindrical radial wall and an end wall, wherein outwardly curved, dome-shaped punching marks are used coaxially to the center of the end wall. It accommodates the rolling bearings of the rotor when assembling household appliances. Through the openings in the radial walls it is also possible to insert the brush structures of the stator into the housing in the direction of the rotor, the brush structures being accommodated by the clip-shaped indentations formed inwardly in the end wall....
