Change-over valve assemblies for water-conducting household appliances and water-conducting household appliances

Abstract

The invention relates to a switching valve assembly (1) for a water-conducting household appliance, which has a valve chamber (5), a valve closing body (6) arranged in the valve chamber, a first output port (8), a second Two output ports (9) and a first input port (10), wherein the first output port, the second output port and the first input port are allocated to the valve chamber. In the operating position, the first output and the second output are arranged in the upper region (12) of the valve chamber. Furthermore, a second input (11) is provided, which is assigned to the valve chamber. The first output and the second output are arranged in the upper region (13) of the valve chamber in the operating position. In this case, the valve closing body is designed as a floatable valve closing body. Furthermore, a delivery device ( 4 ) is provided, which conducts the liquid both via the first outlet and via the second outlet into the valve chamber in order to introduce the liquid into the valve chamber.

Description

technical field [0001] The invention relates to a switching valve assembly for a water-guiding household appliance and a water-guiding household appliance, in particular to a laundry treatment appliance for washing laundry with a switching valve assembly. The invention relates in particular to the field of washing machines and washer-dryers. Background technique [0002] Patent document US 2 918 927 A describes a washing machine. [0003] Publication EP 1 190 666 A2 describes a valve for a dishwasher with a movably arranged closing element. [0004] Publication US 2014 / 286747 A1 describes a pump comprising an impeller. [0005] Publication WO 99 / 27836 A1 describes a washing machine. [0006] Publication GB 2 199 080 A describes a valve assembly. [0007] A switching valve for switching fluid flows is known from DE 87 07 121 U1. A fluid, such as water or air, is fed to the valve via a controlled flow circuit, for example by means of a pump or by means of a blower. The c...

AI Technical Summary

Problems solved by technology

[0008] The switching valve known from DE 87 07 121 U1 has the disadvantage that a sufficiently large fluid flow must always be maintained in order to hold the valve body in the recess of the body, which is used in the corresponding switching position ball bearing area

Here too, there is the problem that the position of the valve body is unstable during brief interruptions or when the fluid flow fluctuates

Here, the reciprocating movement of the elements requires suitable actuating devices, which entails additional costs and additional space requirements and is an additional source of errors
