Embodiment Construction

[0027] The pump 1 shown in Figure 1 is a pump with an integrated, electronically commutated, wet rotor motor for a household appliance (not shown). The pump 1 is usually installed and operated in a domestic appliance in the horizontal orientation shown in FIG. 1 .

[0028] The pump housing 2 consists of a front housing 3 and a pot-shaped cover 4 , which are positively connected to each other. The pump housing 2 of the pump 1 thus forms a one-piece pump chamber 5 which includes a rotor 6 with an impeller 7 inside it. The impeller 7 can be integrated with the rotor 6 .

[0029] The rotor 6 is rotatably supported on the shaft 10 via a front sliding bearing 8 facing the impeller 7 and via a rear sliding bearing 9 facing the shroud 4 . The shaft 10 is rotatably mounted at its front end 11 facing the impeller 6 in a bearing 12 fastened to the front housing 3 via a support arm 13 and at its rear facing the impeller 6 . The end 14 of the apron 4 is supported in a bracket 15 arrange...

Abstract

The invention relates to a pump body for a pump (1), which is provided with a wet running motor and comprises a seat (12) for the wet running motor axis arranged on the inlet side. Said pump is characterised in that the seat (12) is fixed to the body (2) by means of a single supporting arm (13). The pump provided with the a wet running motor and a water supply household appliance are also disclosed.

Description

technical field [0001] The invention relates to a pump housing, a pump, in particular a pump for a water-conducting household appliance and a water-conducting household appliance. Background technique [0002] In pumps for conveying liquids, it is necessary to set an impeller in a rotational motion in a pump chamber through which the liquid is conveyed. This impeller can be driven by a motor, the rotor of which is mounted on a non-rotatable shaft. In order to be able to fix the shaft relative to the pump housing, the shaft must be supported at the end assigned to the impeller in front of the impeller. This fastening or mounting preferably takes place in an axial suction connection of the pump housing. An example of such a fastening of the pump motor shaft is described in DE 103 52 487 A1. [0003] In this pump housing, the rotor of the drive motor is supported on a shaft, which is held at the front end in a mount which is fixed via a support arm in the suction connection ...
