Abstract

A laundry treatment machine for washing and drying has two valve blocks (10a,10b). It features a connecting piece (3) between the water entry openings of the blocks (10a,10b). The piece (3) has two outlet openings connected to the entry openings, and an inlet opening in the form of a tube connection which permits a detachable connection to a water tube.

Description

The invention relates to a laundry treatment machine for washing and drying Laundry with a water connection, a first valve block to control the water supply in the washing process and with a second valve block to control the water supply to a condensation channel in the drying process.

A laundry treatment machine of the type mentioned is, for example, by a washer dryer known as Miele WT 745. To at the pre called washer-dryers the water supply from a tap to the two valves to divide blocks, the inlet hose is connected to a Y-piece. To guarantee ensure that the connection meets the high requirements in terms of tightness is the Connection made permanent. There is the disadvantage that speci for washer dryer All connection hoses must be used.

The invention thus turns the pro it is a problem to design a laundry treatment machine of the type described in the introduction equip the water connection with a standard connection hose for washing machine NEN can be done.

According to the invention, this problem is solved by a laundry treatment machine with the Features of claim 1 solved. Advantageous refinements of the invention result arising from the following subclaims.

The advantages that can be achieved with the invention result from the laying of the branches for the water connection in the valve block area. This allows a standard application end hose with a single water outlet opening can be used. Another The compact design of the connecting piece and the valve blocks provides an advantage to a module, which is prefabricated and checked before installation in the washer dryer can.

Manufacturing is facilitated by positioning on the connector pins are arranged, which interact with positioning holes in the valve block. Further relief results from the fact that a receptacle for a radio interference suppression choke is arranged.  

It is also advantageous that the connection between the outlet openings of the An closing piece and the water inlet openings of the valve blocks by rolled over union nuts. As a result, the tightness of the connection point is high even Water pressure guaranteed.

An example of the invention is shown in the drawings and is described in more detail below described. Show it:

Fig. 1 shows the essential parts of the water supply in a washer-dryer,

Fig. 2, the connector ( 3 ) as a detail.

The dash-dotted line in Fig. 1 indicates the housing ( 1 ) of the washer dryer. In this housing ( 1 ) a water inlet hose, not shown in the drawing, leads, which is connected to the inlet opening ( 2 ) of a connector ( 3 ). For this purpose, the inlet opening ( 2 ) is designed as a hose connection with a thread ( 5 ). (See Fig. 2) The connector ( 3 ) branches into two outlet openings ( 6 a; 6 b), which are provided with a collar ( 7 a; 7 b). These collars ( 7 a; 7 b) are equipped with rolled union nuts ( 8 a; 8 b). The union nuts ( 8 a; 8 b) are connected to the water inlet openings ( 9 a; 9 b) by two valve blocks ( 10 a; 10 b). The first valve block ( 10 a) has three individually controllable solenoid valves ( 11 ), the outputs ( 12 ) of which are connected to the channels ( 13 ) of a detergent dispenser drawer ( 14 ). The second valve block ( 10 b) has two controllable solenoid valves ( 15 ) which are connected to different channels ( 16 ) in a condensation channel ( 17 ). Here, the first channel is used to supply the condensation channel with cooling water, the second to clean the condensation channel from fluff. The water inlet openings ( 9 a; 9 b) of the valve blocks ( 10 a; 10 b) are surrounded by valve holding plates ( 18 a; 18 b), in which holes are arranged. These holes work with positioning pins ( 20 a; 20 b) on the connector ( 3 ) as a positioning aid and anti-rotation device. Furthermore, a receptacle ( 21 ) for a suppression choke is arranged on the connector ( 3 ).

Claims (4)

1. laundry treatment machine for washing and drying laundry with a water connection, a first valve block ( 10 a) for controlling the water supply in the washing process and with a second valve block ( 10 b) for controlling the water supply to a condensation channel ( 17 ) in the drying process, characterized in that between the water inlet openings (9 a; 9 b) of the valve blocks (10 a, b 10) an on is arranged circuit piece (3), which two with the water inlet openings (9 a; 9 b) 6 b output openings (6 connected to a ) and an inlet opening ( 4 ) designed as a hose connection which enables the detachable connection ( 5 ) with a water hose. 2. Laundry treatment machine according to claim 1, characterized in that on the connecting piece ( 3 ) positioning pins ( 20 a; 20 b) are arranged which cooperate with positioning bores arranged on the valve blocks. 3. Laundry treatment machine according to one of claims 1 or 2, characterized in that a receptacle ( 21 ) for a radio interference suppressor is arranged on the connecting piece ( 3 ). 4. laundry treatment machine according to one of claims 1 to 3, characterized in that the connection between the outlet openings ( 6 a; 6 b) of the connector ( 3 ) and the water inlet openings ( 9 a; 9 b) of the valve blocks ( 10 a; 10 b ) by means of rolled union nuts ( 8 a; 8 b).
