Problems solved by technology

[0002] There are many types of heating devices made of one heating wire, such as: electric blankets, electric heating pads, electric heating carpets, electric heating vegetation pads, electric heating table and chair pads, etc. These heating devices usually have only one independent heating area, and the temperature of the entire heating area is the same. Rise and fall at the same time, it cannot be controlled in different areas. If you want to achieve real temperature control in different areas, two or more independent heating wires are generally used to control the temperature in different areas. For example, the patent application document with the publication number CN200994614 is It is disclosed that three heating wires are used to realize temperature control in three independent regions. Such a design will lead to complicated production process, complicated connection lines, complicated circuit control part, uneven heating loop, and high overall production cost, which is not suitable for large-scale mass production and sales of

Embodiment 1

[0029] Such as image 3 As shown, in Example 1, an auxiliary heating resistance wire is used, and the heating blocks are distributed horizontally in the left and right in the fabric interlayer, and the single-wire heating wire is continuously wired in an S-shaped direction up and down, and the single-wire heating wire is arranged in the left and right direction in the same manner as Spacing distribution, from the leftmost end of the fabric layer to the rightmost end, where the main heating resistance wire and auxiliary heating resistance wire in the single-wire heating wire on the left end are connected in series by connecting step-down electronic components, and the single-wire heating wire on the right end leads out to the fabric to connect to the controller , and connected to the power supply, a certain S-shaped bend of the single-wire heating wire is used as a dividing point to form two heating blocks on the left and right.

Embodiment 2

[0031] Such as Figure 4 As shown, in Example 2, two auxiliary heating resistance wires are used, and two S-shaped bends of the single-line heating wire are used as dividing points. At the first dividing point, the first auxiliary heating resistance wire and the main The heating resistance wire is cross-connected internally and externally, and the second auxiliary heating resistance wire is self-connected back and forth. They are connected back and forth to form three heating blocks on the left, middle and right, and the single-wire heating wire at the left end is directly connected to the controller and connected in series on the controller. The other parts of Embodiment 1 and Embodiment 2 are the same.

[0032] Compared with Embodiment 2, the wiring of the single-wire heating wire at the left end is different in Embodiment 1. The single-wire heating wire at the left end of Embodiment 1 is connected directly by connecting a step-down electronic component in series between the...

Embodiment 3

[0034] Such as Figure 5 As shown, Embodiment 3 is the same as Embodiment 1, except that in Embodiment 3, the heating block is distributed vertically in the fabric interlayer, and the single-wire heating wire is continuously routed in an S-shape in the left and right directions, and the upper and lower Distributed at equal intervals in the direction, from the uppermost end of the fabric layer to the lowermost end, and an S-shaped bend at a certain point of the single-line heating wire is used as a dividing point to form two upper and lower heating blocks.

Abstract

The invention relates to a single-line segmented and regional temperature control heating device and a processing method of the heating device. The heating device comprises two fabric layers and a heating layer, wherein the two fabric layers are arranged in an up-and-down overlapping mode, and the heating layer is fixed between the two fabric layers; the heating layer is orderly spread between thetwo fabric layers through a single heating wire to form continuous regional heating blocks, and a turn is arranged at a demarcation point of every two continuous heating blocks; the single heating wire comprises main heating resistance wires and auxiliary heating resistance wires which are arranged adjacently inside and outside, an independent insulation protective layer is arranged on each layerof heating resistance wires, and a resistance value difference exists between each main heating resistance wire and the corresponding auxiliary heating resistance wire; the main heating resistance wire and the auxiliary heating resistance wire at one end of the single heating wire are connected in series, and the main heating resistance wire and the auxiliary heating resistance wire at the otherend of the single heating wire are electrically connected to a control end of a controller separately; and the main heating resistance wires and the auxiliary heating resistance wires are connected ina crossing mode on an inner layer and an outer layer at the demarcation points. Through the heating device, the problem of complicated wire arrangement is solved.
