Embodiment Construction

[0019] A pump 2 acting as a discharge pump for a dishwasher (not shown) has a channel 24 through an inlet connection (not shown) and an outlet connection (not shown), and a pumping chamber 22 Connect to the plumbing of the dishwasher (not shown).

[0020] The impeller 14 is arranged in the pumping chamber 22 and is rotatably located on the shaft 6 . The shaft 6 constitutes a connection to an electric motor 18, such as a BLDC or BLAC motor, which is connected to a control system (not shown) for control purposes of the water-carrying household appliance.

[0021] The impeller 14 has at its front end a valve body 20 which, in the closed position (not shown), abuts against a seal 10 arranged inside the pumping chamber 22 and allows the passage of the pump to be reliably closed. A further seal 12 is also arranged on the pump cover 16 .

[0022] The valve body 20 and the seal 10 together form the valve 4 . The valve body 20 is firmly connected to the impeller 14 and is in particu...

Abstract

The present invention relates to a water-loading household device, especially a dish washing machine or washing machine. The water-loading household device at least comprises a pump (2) which is connected to a pipeline system of water-loading house household device. The pump (2) is connected with a motor (18) and comprises a valve (4) which is provided with a valve body (20) that is installed on the impeller of pump (2) and can axially move. The invention is characterized in that the motor (2) can be driven in two directions. Furthermore the valve (4) is opened or closed according to the rotation direction of motor (18).

Description

technical field [0001] The invention relates to a water-carrying domestic appliance, in particular a dishwasher or a washing machine, according to the preamble of claim 1 . Background technique [0002] Water-carrying domestic appliances, such as dishwashers, have a piping system that is able to conduct rinse water out of the water-carrying domestic appliance and into the domestic wastewater treatment system after the cleaning process has been completed. In dishwashers, a discharge pump is provided for this purpose, which is connected to the pipe system of the water-carrying domestic appliance for this purpose. [0003] EP1767788A1 discloses a discharge pump for a dishwasher which also has a valve function which prevents the flow in a domestic waste water treatment system from causing undesired flow processes in The device is drained. The impeller in the pump is also configured as a valve body and is arranged to be axially displaceable along a shaft on which the valve body...
