portion of the supporting member (14) around the plug (1 1) and which provides the igniter (7) to be mounted and
[0048] - at least one thermocouple hole (13, 1 13) which is formed by punching the portion of the supporting member (14) around the plug (1 1 ) and which provides the thermocouple (8) to be mounted(Figure 5).
[0049] In the oven (1 ) of the present invention, when the burner (4) is mounted to the casing (3), first the supporting member (14) is mounted to the end of the tubular member (5) by snap-fit method or being nailed by means of the plug (1 1 ) and leak-proofing is provided by applying all around solder or welding to the joint of the plug (1 1) and the tubular member (5). Then the supporting member (14) is mounted to the lower wall of the casing (3) or to the upper wall of the casing (3) by means of the fixing tab (10) according to where the burner (4) will be used and the assembly process is completed by mounting the igniter (7) to the igniter hole (12, 1 12) thereon and the thermocouple (8) to the thermocouple hole (13, 1 13).
[0050] The supporting member (14) provides leak-proofing by blocking the end of the tubular member (5), bears the tubular member (5) at a certain distance to the casing (3) on the casing (3). The igniter (7) and the thermocouple (8) is mounted onto the supporting member (14), all of the said
connections is performed on the supporting member (14) produced as a single-piece. The number of elements required for mounting the burner (4) to the casing (3) is decreased; labor benefit and convenience of maintenance in case of any malfunction are provided.
[0051] The burner (4) is mounted to the lower wall of the casing (3) or the upper wall of the casing (3) by not changing the position wherein the reflector (9) is at the top according to the exit openings (6), that is, by not being rotated, only the position of the supporting member (14) is changed by being rotated 180 degrees around the tubular member (5) axis in order to mount the burner (4) to the lower wall of the casing (3) or the upper wall of the casing (3). When the burner (4) is mounted to the lower wall of the casing (3), the fastening tab (10) is located at the bottom, when the burner
(4) is mounted to the upper wall of the casing (3), the supporting member (14) is fixed to the end of the tubular member (5) at the 180 degrees rotated position with respect to its lower position without rotating the burner (4). In this case the fastening tab (10) is at the upper side of the supporting member (14). The supporting member (14) is mounted for mounting the burner (4) to the lower wall of the casing (3) or to the upper wall of the casing (3) by only being rotated without any modifications thereon.
[0052] In an embodiment of the present invention, the supporting member (14) comprises two igniter holes (12, 1 12) which provide the igniter (7) to be used in two different positions according to the lower and upper positions at which the burner (4) is mounted to the lower wall of the casing (3) or mounted to the upper wall of the casing (3), which are located at the right and the left of the plug (1 1 ), which are symmetrical to the tubular member
(5) axis and only to one of which, located at right or left according to the lower or upper positions of the burner (4), the igniter (7) is mounted. When the burner (4) is at the lower position, the igniter (7) is mounted to the igniter hole (12) at one side of the plug (1 1 ) and the other igniter hole (1 12) remains empty, when the burner (4) is at the upper position, this time the igniter hole (12) used at the lower position remains empty, and the other igniter hole (1 12) is used.
[0053] In another embodiment of the present invention, the supporting member (14) comprises two thermocouple holes (13, 1 13) which provide the thermocouple (8) to be used in two different positions according to the lower and upper positions at which the burner (4) is mounted to the lower wall of the casing (3) or mounted to the upper wall of the casing (3), which are located at the right and the left of the plug (1 1 ), which are symmetrical to the tubular member (5) axis and only to one of which, located at right or left according to the lower or upper positions of the burner (4), the thermocouple (8) is mounted. When the burner (4) is at the lower position, the thermocouple (8) is mounted to the thermocouple hole (13) at one side of the plug (1 1 ) and the other thermocouple hole (1 13) remains empty, when the burner (4) is at the upper position, this time the thermocouple hole (13) used at the lower position remains empty, the other
thermocouple hole (1 13) is used.
[0054] In another embodiment of the present invention, in the supporting member (14) the distance between the igniter hole (1 12) used at the upper position of the burner (4) and the fastening tab (10) is more than the distance between the igniter hole (12) used at the lower position of the burner (4) and the fastening tab (10). Similarly, the distance between the second thermocouple hole (1 13) at the upper position of the burner (4) and the fastening tab (10) is more than the distance between the thermocouple hole (13) used at the lower position of the burner (4) and the fastening tab (10). These distance differences result from the reflector (9) being mounted to the lower and the upper walls of the casing (3) at the same position (without being rotated).
[0055] In another embodiment of the present invention, the supporting member (14) comprises two thermocouple mounting tab (15) which are formed by bending slightly the edges of the supporting member (14) on which the first and the second thermocouple holes (13, 1 13) are located towards the tubular member (5) and which provides the thermocouple (8) mounted to the first or the second thermocouple holes (13 or 1 13) at the lower and upper utilization positions of the burner (4) to extend angularly towards the tubular member (5).
[0056] Moreoever the supporting member (14) mounted around the tubular
member (5) by the plug (1 1 ) portion thereof being punched in diameter of the tubular member (5) is used for supporting the tubular member (5) in L form on the casing (3) at the points except the end portion thereof, for example, for supporting the short arm thereof which forms the L form of the tubular member (5).
[0057] The supporting member (14) of the present invention provides leak-proofing by blocking the end of the tubular member (5) and supports the tubular member (5) by holding it at a certain distance from the casing (3). The supporting member (14) provides the igniter (7) and the
thermocouple (8) to be fixed at appropriate positions by means of the igniter holes (12, 1 12) and the thermocouple holes (13, 1 13) located thereon. The supporting member (14) also provides the igniter (7) and the thermocouple (8) at appropriate positions according to the lower and upper positions wherein the burner (4) is used at the lower portion or at the upper portion of the oven cavity (2). The supporting member (14) furthermore provides the thermocouple (8) to extend angularly to the tubular member (5) by only the edges thereof being bent, thus the number of elements required for mounting the burner (4) to the casing (3) is decreased, advantage in terms of material, moulding, labor and maintenance is provided by producing the supporting member (14) at one type according to the various utilization positions.
It is to be understood that the present invention is not limited by the embodiments disclosed above and a person skilled in the art can easily introduce different embodiments. These should be considered within the scope of the protection postulated by the claims of the present invention.
