The fitting hook is provided at an angle α with respect to the upper end 51. In particular, in order to attach a convection heating device, the wall frame edge is first fixed to the wall by means of through-holes 54 and corresponding screws. First, the heating device is fitted into the lower end 52 of the wall frame edge, and the fitting hook 53 bent by the angle α is inserted into a hole formed in the rear wall 30 of the heating device until the fitting hook 53 is fitted. Introduce. By the inclination of the fitting hook by the angle α, the fitting hook can better hit the hole formed in the rear wall 30 of the heating device, and the fitting hook 53 can be better guided into the hole.

  FIG. 19 shows a perspective view of a holder for a heating element of a heating device.

  Here, the holder for the heating body 80 has a fixed unit 60 and a spring element or spring unit 70. The fixing unit 60 is fixed to the housing, in particular to the lower part of the housing. At this time, the fixing unit 60 is coupled to the heating body 80 by the spring element 70. In order to catch the elongation of the heating body 80 due to heating, it is preferable to design the element 70 as a spring element.

  FIG. 20 shows a perspective view of the fixing unit 60 and the spring element 70 fixed to the heating body 80.

  FIG. 21 shows a perspective view of another embodiment of the fixing unit 60 and the spring element 70.

  FIG. 22 shows a perspective view of the holder for the fixing unit 60 and the spring element 70, ie for the heating body 80.

  FIG. 23 shows a perspective view of the fixed unit 60.

  The fixed unit 60 has a lower side 62. This lower side is formed to be fixed to the housing of the heating device. Furthermore, the fixing unit 60 has a second portion 63 that is used to accommodate the spring unit 70.

  FIG. 24 shows a perspective view of the spring element of the holder for the heating element.

  The spring element 70 has a first end 71 which is inserted and fixed in the second part 63 of the fixing unit. The spring element 70 has a first arm 72 and a second arm 73. Each of the two arms has curved portions 72a and 73a. This part is used to be put into the heating body. It is preferable to place these ends between two stacks of heating elements. The first arm 72 of the spring element 70 is longer than the second arm 73 and is at least partly corrugated. Therefore, this arm can be better placed between the two stacks of heating elements and a greater fixation of the surface can be achieved. Therefore, the absorption of force and rotational torque acting on the heating element can be improved by the spring element.

  FIG. 25 shows a schematic diagram of the fixed unit 60.

  The fixing means 60 has a lower side 62. This lower side is preferably connected to the housing of the heating device. The second portion 63 is used to accommodate the first end 71 of the spring element 70. It is preferable that the fixing unit 60 is made of plastic.

  FIG. 26 shows a schematic cross-section of a fixed unit with a spring element 70 inserted.

  Here, the first end 71 of the spring element 70 is inserted around a bolt 69. Therefore, a portion of the first end 71 engages behind the protrusion 68.

  FIG. 27 shows a schematic diagram of a spring element representing an alternative embodiment.

  The spring element 70-1 is manufactured substantially from a thin plate. The thin plate has a lower portion 71-1. The open end of this part is bent similarly. Two fixing units 72-1 and 73-1 are provided at the other end of the spring element 70-1. These fixing units are used to be placed between two stacks of heating elements.

  FIG. 28 shows a schematic cross-sectional view of the end of the heating element and spring element 70.

  Here, in particular, the first arm 72 of the spring element is shown. This arm is placed in a hole formed in a plurality of stacks of heating elements.

  FIG. 29 shows a different cross-sectional schematic view of the end of the arm of the spring element 70.

  FIG. 30 shows two schematic cross-sections of the fixing unit and the lower part of the spring element.

  FIG. 31 shows a spring element 70 with the first end 71 having a fixing unit 60 and a fixing plate 61 unbent.

  The spring element 70 is bent in a U-shape in the region of the first end 71, and is substantially in the same plane, preferably in the same plane, at this end 71. It does not have a bent part protruding from. The spring element 70 is further inserted into the fixing unit 60 through the punched portion 64. The fixing plate 61 is pushed into the tunnel 65 of the fixing unit 60 and locked, and fixes the first end 71 of the spring element 70. It is preferable that the fitting hook 66 of the fixing plate 61 is fitted to the undercut portion or the punched portion 67. In order to securely fix the fixing plate 61, it is preferable that the fixing plate is located at an interval X from the outer surface 60a of the fixing unit 60, and on the opposite side, the fixing plate 61 protrudes from the outer surface 60b of the fixing unit 60 by a dimension Y. ing. Conveniently, the spacing X and the dimension Y are at least about 0.5 mm, in embodiments about 2 mm. At the time of attachment, the fixing plate 61 can be pushed into the fixing unit 60 using a simple tongue. This achieves that the fixing plate 61 is securely fitted, that is, that the fitting hook 66 can be reliably pushed into the punched portion 67. Instead of fitting the fixing plate 61, the fixing plate can be fixed or pasted or friction welded by screws or cotters. The fixing plate 61 has at least one fitting ramp 61a having an angle of 1 to 45 °, preferably about 10 °. Similarly, the fixed unit 60 has at least one insertion inclined portion 60c or a phase.

  FIG. 32 shows a spring element 70 having a flat first end 71 as described with reference to FIG.

  The second end 74 has a first arm 72 and a second arm 73. The first arm 72 is designed with multiple bent portions on the same surface as the first end 71 is designed. First, the bent portion 72c is bent about 90 ° outward, and two bent portions 72d bent about 45 ° to 90 ° inward are continuously located, followed by a 45 ° rising portion 72c. In the extension of the first arm 72, a longer straight portion 72f and a 90 ° hook 72g extend downward. However, the hook may be designed upward. A second arm 73 having a substantially V-shaped or U-shaped bent portion 73b is provided to face each other. Here, the V or U shape is bent outwardly from the surface of the first end 71, preferably about 90 °. These arms are engaged with a heating element (not shown in FIG. 32), and the hook 72g of the first arm 72 is engaged with or inserted into the V-shaped or U-shaped hook 73b of the second arm. It may be locked. It is advantageous for the spring element 70 to be located in a contact area 64a which is V-shaped or in a stretched line and which progressively opens upwards. These contact areas together with the fixed plate 61 form a passage that opens upward.

  As shown in FIG. 33, the opening is upwardly wider by 0.3 to 3 mm than the bottom of the opening, that is, the diameter of the wire. In FIG. 33, the opening is shown exaggerated to show the close contact of the element 70. This also applies to a spring element made of a thin plate having a square outline by analogy. The rod 75 of the spring element 70 comes into strong contact with the contact region 64a according to the expansion of the heating body 80 due to heating, and in close contact with the shape of the contact region 64a, particularly in the upper part. In the lower region of the contact region 64a, a cylindrical region is provided up to a height Z of about 3-5 mm. The purpose is that the rod 75 is firmly embedded below and does not rattle. Accordingly, the heating body 80 is securely fastened and held during transportation and in an attached state. During the heating operation, the heating body expands during heating of the heating body 80, and the longitudinal elongation is absorbed by the sticking of the rod 75 to the contact region 64a and the elastic deformation of the rod 75 (illustrated by a broken line).
