[0026] Example:

[0027] Reference Figure 1-Figure 5The present embodiment provides a high-efficiency dehumidifying dryer heater, comprising a fixing plate 1, a main board and a heating wire 2. The heating wire 2 is composed of a plurality of ring structures to form a spiral structure, wherein the fixing plate 1 is installed at the installation position of the dryer by screwing screws into the positioning hole 5, the main board is arranged in the middle of the inner cavity of the main board, and the heating wire 2 is fixed above and below the main board in a set configuration. The heating wire 2 is commonly a whole resistance wire, which can be coiled to form a variety of shapes.

[0028] like Figure 1 As shown, the main board is provided with a plurality of wire clamping parts 3 for keeping the heating wire 2 in a certain shape, the wire clamping part 3 includes a first limiting part 11 and a second limiting part 12 arranged in parallel, the first limiting part 11 and the second limiting part 12 each include two limiting points, and the two ends of the bottom of the same annular structure are respectively limited between two limiting points on the diagonal line in the first limiting part 11 and the second limiting part 12, so that the annular structure is kept fixed along its own installation direction; the annular structure is obviously one of the spiral structures of the heating wire 2, and the heating wire 2 is formed by connecting several spiral structures end to end. The annular structure mentioned in this embodiment, the part fixed to the wire clamping part 3 is usually the inclined part at the bottom, and the details can be referred to Figure 3 Obviously, since the bottom part is inclined, Figure 3 For example, it is obvious that when limiting, the front end of the annular structure acts on the front end of the first limiting portion 11, and the rear end of the annular structure acts on the rear end of the second limiting portion 12, so that the annular structure forms a clamping position in the above space. It is obvious that the four limiting points have two diagonals, and the two diagonals are in different directions, which can correspond to the positive or negative spiral directions of the spiral heating wire 2, so no matter what form the heating wire 2 is installed in, the clamping part 3 can be fixed.

[0029] Of course, in addition to using Figure 3 In addition to the structure shown, other optional embodiments may be provided, for example: two identical columnar clamping bodies are provided, and clamps are provided at both ends of the clamping bodies (corresponding to the aforementioned limiting points), and the two clamping bodies are arranged parallel to each other so that the four clamps form a rectangular or parallelogram distribution, and the above two clamping bodies are respectively the first limiting portion 11 and the second limiting portion 12, and the clamps on the two clamping bodies are respectively marked as a, b and c, d, wherein ac forms a diagonal line, and bd forms a diagonal line, and correspondingly, when the annular structure is engaged, it acts on ac or cd to form a clamping position. The above-mentioned clamping portion mainly forms an inclined configuration to match the inclination of the bottom of the annular structure of the heating wire 2 when it is actually installed, so as to ensure that the installation is simple and stable, and the heating wire 2 will not be excessively bent, thereby reducing the wear of the heating wire 2 during installation and use.

[0030] The following are all adopted Figure 1 The wire clamping part 3 shown in the figure will be described in detail.

[0031] Among them, reference Figure 3 The clamping portion 3 includes an enlarged hole 8, and a first limiting portion 11 and a second limiting portion 12 are formed on both sides of the bottom of the enlarged hole 8; the cross section of the enlarged hole 8 is preferably as follows Figure 3 In order to facilitate the installation of the heating wire 2, the wire clamping part 3 also includes a reduced diameter hole 10, which is arranged on the top surface of the wire clamping part 3, and the bottom of the reduced diameter hole 10 is the top of the expanded diameter hole 8. The expanded diameter hole 8 and the reduced diameter hole 10 form an hourglass-shaped groove structure; obviously, through the arrangement of the reduced diameter hole 10, the top opening of the reduced diameter hole 10 is large and has a guiding effect downward, so that the heating wire 2 is easier to install. After installation, due to the small top opening of the expanded diameter hole 8, the bottom of the annular structure in the heating wire 2 is as shown in FIG. Figure 3 As shown, the heating wire 2 is stuck between the first limiting portion 11 and the second limiting portion 12, thereby completing the fixation. After being fixed in this way, several annular structures of the heating wire 2 at the installation location can be as shown in FIG. Figure 3 The positioning and separation shown in the figure have good fixing effect and are easy to operate. Preferably, the edge of the bottom of the enlarged diameter hole 8 is rounded, and the rounded corner design is rounded at the two inclinations at the bottom of the enlarged diameter hole 8, so that friction can be effectively reduced when the heating wire 2 is limited.

[0032] Continue to refer Figure 3 , a rotating shaft 13 and a slider 9 are sequentially provided at the bottom of the wire clamping part 3, a fixing groove 4 is provided on the main board, and the slider 9 slides in the fixing groove 4, and the rotating shaft 13 has a limited rotation range a in both positive and negative directions starting from the return angle of the wire clamping part 3, wherein 10°≤a≤30°. The slider 9 is provided with a fixing hole 19, and the fixing hole 19 is suitable for fixing the slider 9 at a set position. In this embodiment, the wire clamping part 3 has a small-angle rotation space, and the reason for this is that when the heating wire 2 is coiled and installed, its installation direction may not be exactly along the direction of the shrinking hole 10 or the expanding hole 8, and there may be a certain angle difference, and the rotating shaft 13 enables the wire clamping part 3 to have a small-angle rotation space, which can be fine-tuned during installation to adapt to the initial angle of the heating wire 2 when it is installed. Figure 1 When the wire clamping parts 3 are arranged at multiple locations, the multiple wire clamping parts 3 restrict each other so that the heating wire 2 can still be stably installed, and the installation stability will not be affected by the rotation space of the wire clamping parts 3. How to set the rotation range of the rotating shaft 13 is a prior art and will not be described in detail in this embodiment.

[0033] like Figure 1 , Figure 4As shown, this embodiment proposes a preferred embodiment of the wiring terminal 6, which is intended to facilitate the installation of the heating wire 2. The heater also includes a pair of wiring terminals 6 and a potential connection point 7 connected to the wiring terminals 6; the wiring terminal 6 has a wire hole 16 and a clamping structure, and a conductive part 17 is provided at the bottom of the wire hole 16. The end of the heating wire 2 passes through the wire hole 16, and then the clamping structure is adjusted to press the end of the heating wire 2 against the conductive part 17, and the conductive part 17 is connected to the wiring terminal 6. The clamping structure includes a threaded adjustment screw 14 and a clamping portion 15 mounted at the bottom of the adjustment screw 14 through a bearing; preferably, the axial length of the clamping portion 15 is greater than the axial length of the conductive portion 17, and the conductive portion 17 extends out of or is recessed in the inner wall of the wire hole 16; when the clamping portion 15 clamps the end of the heating wire 2 against the conductive portion 17, the adjustment screw 14 moves downward during rotation, so that the clamping portion 15 presses the end of the heating wire 2 and is close to the conductive portion 17, and at the same time, the end of the heating wire 2 is slightly deformed along the outer wall of the conductive portion 17 to form a folded line structure there, so that the end of the heating wire 2 can be better installed in the wire hole 16. The conductive portion 18 is connected to the outside of the conductive portion 18, and is connected to the terminal 6 through the conductive portion 18, so that the heating wire 2 can be energized.
