Abstract

The present invention relates to a washer fluid distribution device ( 1 ) comprising a connectors support ( 9 ) comprising a base ( 31 ) equipped with a fixing device ( 18 ) configured to hold at least one hydraulic coupling ( 7, 8 ) at a location on the base ( 31 ), characterized in that a housing ( 35 ) accommodating a heating element ( 36 ) of the distribution device ( 1 ) is formed in the connector support ( 9 ), a wall portion delimiting the housing ( 35 ) being intended to be in contact with the at least one hydraulic coupling ( 7, 8 ).
The present invention also relates to a washing and/or wiping system comprising a distribution device ( 1 ).

First claim

1 . A washer fluid distribution device comprising:
a connector support comprising a base equipped with a fixing device configured to hold at least one hydraulic coupling at a location on the base wherein a housing accommodating a heating element of the distribution device is formed in the connector support, a wall portion delimiting the housing being intended to be in contact with the at least one hydraulic coupling.

2 . The distribution device according to claim 1 , wherein the housing accommodates a heat-conducting resin coating the heating element, the heat-conducting resin being in contact with the walls of the housing.

3 . The distribution device according to claim 1 , wherein the connector support comprises a retaining cap collaborating with the base to be fixed to the base over the location of the at least one hydraulic coupling that is intended to be held in place by the fixing device.

4 . The distribution device according to claim 3 , wherein the retaining cap is fixed to the base by clip-fastening.

5 . The distribution device according to claim 3 , wherein the housing is formed in a retaining cap of the connectors support.

6 . The distribution device according to claim 5 , wherein the retaining cap is made of a heat-conducting plastic material or of a metallic material.

7 . The distribution device according to claim 1 , wherein the housing is formed in the base of the connectors support underneath the location for the at least one hydraulic coupling intended to be held in place by the fixing device.

8 . The distribution device according to claim 7 , wherein the base of the connectors support is made of a heat-conducting plastic material or of a metallic material.

9 . The distribution device according to claim 1 , characterized in that the housing has at least one lateral opening for the passage of the electric wires of the heating element.

10 . The distribution device according to claim 1 , wherein the fixing device has a cavity of cylindrical overall shape defining the location intended to accommodate the at least one hydraulic coupling, the said cavity having:
a first opening configured for the passage of at least one inlet of the at least one hydraulic coupling, a second opening configured for the passage of at least one first outlet of the at least one hydraulic coupling, and a third opening configured for the passage of at least one second outlet of the at least one hydraulic coupling.

11 . A washing and/or wiping system, comprising a distribution device according to claim 1 .
