Abstract

Gas circuit (1) for a kitchen appliance (2) comprising a gas rail (3) with a gas inlet (4) for connecting said gas rail (3) to a gas source (5) and with at least one gas outlet (6), said gas circuit (1) further comprising a gas tube (7) for providing gas from said gas outlet (6) to a gas hob (8), and said gas circuit (1) further comprising a gas valve assembly (9) connecting said gas tube (7) to said gas outlet (6) of said gas rail (3) in a flow conducting manner, said gas valve assembly (9) comprising a gas valve (10) with a valve body (11) and fixation means (12) fixing said valve body (11) to said gas rail (3) such that said gas valve (10) is supported by said gas rail (3), characterized in that said fixation means (12) comprise a first spring member (13a) looping around said gas rail (3) and/or said valve body (11), thereby resiliently bracing said gas valve (10) and said gas rail (3).

First claim

The invention claimed is:

1. A gas circuit for a kitchen appliance comprising a gas rail with a gas inlet for connecting said gas rail to a gas source and with at least one gas outlet, said gas circuit further comprising a gas tube for providing gas from said gas outlet to a gas hob, and said gas circuit further comprising a gas valve assembly connecting said gas tube to said gas outlet of said gas rail in a flow conducting manner, said gas valve assembly comprising a gas valve with a valve body and fixation means that fix said valve body against said gas rail such that said gas valve is supported by said gas rail, wherein said fixation means comprises at least one spring member enclosing said gas rail and said valve body, thereby resiliently bracing said gas valve and said gas rail.

2. The gas circuit according to claim 1 , wherein said gas outlet of said gas rail is an opening of said gas rail, wherein said gas valve comprises an inlet duct, said inlet duct being at least partially inserted into and/or sealed to said opening.

3. The gas circuit according to claim 2 , said opening being arranged in a side wall of said gas rail.

4. The gas circuit according to claim 1 , wherein said at least one spring member comprises attachment means at two opposite sides, said attachment means being any of hooks, bails, grooves and spring-loaded edges.

5. The gas circuit according to claim 4 , wherein the fixation means comprise(s) a locking member, wherein said attachment means attach said at least one spring member to said locking member wherein said at least one spring member and said locking member together enclose both said gas rail and said valve body, or wherein said attachment means at opposite sides of said at least one spring member are mutually attached to each other wherein said at least one spring member encloses both said gas rail and said valve body.

6. The gas circuit according to claim 1 , wherein said at least one spring member has at least one contact zone contacting said gas rail or said valve body, wherein said at least one spring member further has a spring zone spring-loading said contact zone against attachment means.

7. The gas circuit according to claim 1 , wherein said at least one spring member has at least two contact zones respectively contacting said gas rail and/or said valve body, wherein said at least one spring member further has a spring zone spring-loading said contact zones against each other.

8. The gas circuit according to claim 1 , wherein said gas tube is connected with said gas valve in a flow conducting manner, wherein said gas tube is inserted into and/or sealed to a gas outlet of said valve body and resiliently fixed to said valve body by means of said at least one spring member.

9. The gas circuit according to claim 8 , wherein at least one of said at least one spring member and said locking member is made from sheet metal.

10. A kitchen appliance comprising the gas circuit according to claim 1 .

11. The gas circuit according to claim 1 , said at least one spring member comprising first and second spring members that together enclose said gas rail and said valve body.

12. A gas valve assembly for a gas circuit, said gas valve assembly comprising a gas valve with a valve body and fixation means configured to fix said valve body against a gas rail of said gas circuit such that said gas valve is supported by said gas rail, wherein said fixation means comprises at least one spring member arranged for enclosing said gas rail and said valve body, thereby resiliently bracing said gas valve and said gas rail.

13. A fixation means for a gas valve assembly for a gas circuit, said fixation means being configured to fix a valve body of a gas valve of said gas valve assembly against a gas rail of said gas circuit such that said gas valve is supported by said gas rail, wherein said fixation means comprises at least one spring member arranged for enclosing said gas rail and said valve body, thereby resiliently bracing said gas valve and said gas rail.

14. A gas circuit for a kitchen appliance comprising a gas rail having a gas outlet, a gas valve comprising a valve body and an inlet duct, said valve body being seated directly against said gas rail such that said inlet duct is received within said gas rail through said gas outlet, and fixation means for fixing said valve body against said gas rail such that said gas valve is supported by said gas rail, said fixation means comprising at least one spring member enclosing said gas rail and said valve body to thereby resiliently brace said gas valve and said gas rail together under a spring tension of said at least one spring member without screwing components, said at least one spring member possessing sufficient interfacial area with at least one of said valve body and said gas rail to ensure precise positioning thereof upon resilient closure of said at least one spring member via a snap action to brace said gas valve and said gas rail together, said fixation means being devoid of any further supporting element that is secured or mounted to a wall of the appliance, said gas circuit being screw-free.

15. The gas circuit according to claim 14 , said at least one spring member comprising opposing ends, each of said opposing ends being secured to said gas valve via respective cooperating locking members on the valve body.

16. The gas circuit according to claim 14 , said gas valve further comprising a gas tube in fluid communication with a gas outlet duct of said gas valve to carry gas delivered through said gas rail, via said valve and out from said gas outlet duct to said appliance, said fixation means further resiliently bracing said gas tube to said gas valve such that said fixation means is effective to fix both said gas valve and said gas tube onto the gas rail.

17. The gas circuit according to claim 16 , said at least one spring member being effective to fix both said gas valve and said gas tube onto the gas rail.

18. The gas circuit according to claim 14 , said at least one spring member comprising first and second spring members that together enclose said gas rail and said valve body.
