Definitions

• 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.
• 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.
• the clip yields and settles into a slot.
• the clip returned to its original position by the user, grips the heater and fixes it to its working position.
• 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.
• the apparatus for fixing disclosed in the present invention 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.
• 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.
• 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 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.

• Figure 9. is the perspective view of the fixing apparatus and the heater.
• Figure 10. is the side view of the fixing apparatus and the heater.
• the items in the drawings are each numbered and the numbers corresponding to the items are listed below.
• an oven which comprises an oven cabin (5); a heater (4), one end of which is connected to one of the vertical walls of the cabin
• 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.
• FIG 3 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').
• 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.
• 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').
• FIGs 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.
• both arms (31 , 31 ') are joined at the mid section (32).
• 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.
• 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.
• 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).
