DESCRIPTION

AN APPARATUS FOR FIXING HEATER

Technical Field

The present invention is related to an apparatus for fixing heater which enables cylinder heaters used in electrical ovens to be mounted and dismantled rapidly.

Prior Art There are various types of household electrical ovens and they are widely used in the prior art. Generally, these ovens use cylinder heaters as the heating element and these are placed in the upper and lower portion of the oven cabin. In general, these heaters are fixed in such a way to the oven cabin, that it is not very easy for the user to dismantle them. During the process of cooking, the steam from the food within the oven or sometimes the food itself can come in contact with these heaters. This can cause accumulation and decay on the surface of the heater leading to loss of efficiency and low yield from the oven.

One of the examples of cases for easy dismantling of oven heaters can be found in the published patent application No. EP1464894. The apparatus for fixing heater disclosed in this application is used to fix a heater to the ceiling of the oven cabin, the -end point of which can pivot around itself to move up or down as desired. The clip used here grips the front portion of the heater with the power of a spring and thus fixes the heater to the ceiling. To dismantle the heater, the clip is pulled back, enabling the point of the heater to become free. At the same time, the clip yields and settles into a slot. To mount the heater again, the heater is rotated upwards and then the clip is freed from the slot. The clip returned to its original position by the user, grips the heater and fixes it to its working position.

Brief Description of the Invention

The invention disclosed herein enables the heater and the clip to attach, without the need to touch the clip, just by pushing the heater upwards. With the apparatus for fixing disclosed in the present invention, the mounting and dismantling of the heater can be realized far more practically compared to the previous technical field. The oven with the apparatus for fixing heater, which is the subject of the present invention, has been developed in such a way as to enable easy mounting and dismantling of cylinder heaters. The cylinder heater is attached from one of its points to a vertical wall within the oven cabin through a hinge. The fixing apparatus grips the opposite end of the heater, fixing it to the cabin ceiling. By using the apparatus which is the subject of the present invention, to stabilize the heater, the free end of the heater is only pushed upwards and at the same time the fixing point of the apparatus is fitted into the slot within the clip, by itself. To do this, the fixing clip of the apparatus which acts as a spring and the connection plate is utilized. To dismantle, the clip is pushed backwards, which frees the heater.

The Aim of the Invention

The aim of the present invention is to provide a fixing apparatus which enables easy mounting and dismantling with a single motion, of cylinder heaters used in electric ovens.

Detailed Description of the Invention

With the present invention, an oven is developed which comprises an oven cabin (5); a heater (4), one end of which is connected to one of the vertical walls of the cabin

(5) with a turning hinge; and an apparatus for fixing heater (1) mounted to the ceiling of the cabin (5) and connected to the other end of the heater. In Figures 1 and 2, the apparatus for fixing heater (1), which is the subject of the present invention, the application of which is shown within an oven cabin (5), comprises a connecting plate (2) fixed to the ceiling of the oven cabin (5); a fixing clip (3) which is attached to the plate (2) and to which the cylinder heater is mounted. (Detailed perspective view of the fixing apparatus is shown in Figure 3, while the front, side and top views are shown in Figure 4.)

The connecting plate (2) shown in Figures 5 and 6, is formed by shaping a plate. The connecting plate (2) bent in the shape of "U" comprises top and bottom surfaces (21 , 22) approximately parallel to each other; a base portion (23) bent in the shape of a circle where the two surfaces (21 , 22) meet; a connecting flap (21 ') formed by the top surface (21) bending at an angle; another connecting flap (22') approximately parallel to the aforementioned connecting flap (21') formed by the bottom surface (22) bending yet at another angle; and two approximately concentric bores (24, 24') at the mid point of both flaps (21', 22').

At the section where the top surface (21) and the connecting flap (21') attached to it meet; there are two support surfaces (25, 25') on both sides of the surface (21) approximately parallel to each other, the free ends of which are pointed upwards from the top surface (21), and the fixed points folded on top of the connecting flap (21 '). When the connecting plate (2) is mounted on the cabin ceiling, the top surface (21) is positioned opposite to the ceiling and a connecting element, for example a screw, is threaded through the bores (24, 24') to mount the plate (2) to the ceiling. The aforementioned support surfaces (25, 25') are positioned to the two corresponding cavities on the cabin ceiling and the rotation of the connecting plate (2) mounted on the ceiling with the aforementioned connecting element, is thus prevented.

At the section where the bottom surface (22) is connected to the base section (23) which is bent to form a circle, the inflated portion (26) formed towards the top, continues to maintain the circular form of the base section (23) and at the same time forms the base section (23) into a slot into which one point of the fixing clip can slide.

In the section where the inflated portion (26) ends and towards the connecting flaps

(22'), the bottom surface (22) continues almost parallel to the top surface (21) approximately at a distance equal to the diameter of the base portion (23) and then with a bend (27) comes nearer to the top surface (21), to continue towards the connecting flap (22').

In Figures 7 and 8, different perspective views of the fixing clip (3) are shown. The clip (3) is formed by twisting of a wire. The lower portion is formed by bending the two lower arms (31 , 31 ') which are approximately parallel to each other (relative to the vertical plane (Z) of the fixing clip (3)), at an arc. At the very lower end of this form, both arms (31 , 31 ') are joined at the mid section (32). On the other side, both of the arms (31 , 31 ') are twisted coaxially and towards opposite directions to form a couple of bends (33, 33'), and then these bends (33, 33'), are twisted in a circular form towards the mid section (32) at an approximate equal radius nearly parallel to each other. The slot (36) formed by the aforementioned bends (34, 34') (shown in Figure 4), is pointed upwards and the wire of the heater can be positioned on top of it.

After the bends (34, 34') there are two arms (35, 35') which continue upwards at a straight line. One of these arms (35, 35') continues upwards with a tighter angle relative to the other. In other words, although these two arms (35, 35') continue approximately parallel towards the vertical plane (Z) of the fixing clip (3), they form an angle between them relative to their position (as shown in Figure 4). At the end point of these arms (35, 35'), there are end points (37, 37') continuing approximately parallel and opposite to each other formed at a right angle bend to the arms. As shown in Figures 3 and 4, one of these end points (37, 37') should be embedded in the aforementioned base portion (23) while the other one should be embedded within the channel (28) with the flexing of the clip (3).

The attached state of the heater (4) and the fixing apparatus (1) is shown as a perspective and sideways view in Figures 9 and 10. The positions given in these figures are for the mounted form at the ceiling of the oven cabin. The horizontal rod (41 ) at the front part of the heater (4) fits into the slot (36) on the fixing clip (3). The other end of the heater (4) is hooked to the opposite wall of the oven cabin with a hinge allowing the heater (4) to turn up or down. In this way, the heater (4) is hanged between the back wall of the oven cabin and the fixing apparatus. When the rod (41) at the end of the heater (4) is detached from the fixing clip (3), since the back side of the heater is attached to the cabin wall with a hinge, the front portion of the heater is brought down by twisting it. The back side also can be dismantled in different ways by the user as required (not shown in the Figures).

In order to separate the heater (4) from the clip (3), all that is needed is to turn the clip (3) towards the inside of the cabin (shown in Figure 10 as anti-clockwise (T)). With this turn, the top surface (21) and the bottom surface (22) of the connecting plate (2) turn by yielding and the aforementioned rod (41) is freed from its slot. After the heater (4) is freed from the slot (36) as stated above, it takes the previous position of the yielding clip (3) (the mounting position of the heater (4)). When the heater (4) is mounted again, its end point needs to be pushed upwards. The rod (41) first comes into contact with the curved arms (31 , 31 '). Following this, the motion yields the clip (3) and the connecting plate (2) and turns them again towards the oven cabin. Once the contact of the rod (41) with the arms (31 , 31 ') stop, the clip (3) goes back to its previous position by itself and the rod (41) is in position to slide into the slot (36). As can be seen from this, it is possible to mount and dismantle the heater (4) with a single motion.
