Description

Technical Field

[0001] This utility model belongs to the field of mattress technology, specifically relating to a width-zone heating device and a width-zone heating mattress. Background Technology

[0002] Some mattresses have a heating function. Current mattress heating devices generally use evenly distributed resistance wires or carbon fiber heating strips, without considering the different heat requirements of the human body across the left, center, and right sides. Specifically, more heat is lost on the left and right sides, and less in the center. When the heating strips are evenly distributed across the left, center, and right sides, the body feels a significant temperature difference, which is even more noticeable when lying on one's side.

[0003] Furthermore, most existing mattress heating devices use a single heating strip (not considering left and right partitions) and distribute the heating heads evenly by bending them. If the heating strip breaks in any part, the entire heating device will fail. In addition, to achieve the bending effect, the heating strip uses a circular cross-section, which has a lower heat utilization rate and is prone to causing discomfort.

[0004] Therefore, there is room for improvement in the zoned heating structure of mattresses. Summary of the Invention

[0005] This invention addresses the shortcomings of existing mattress zone heating structures that fail to consider the differences in heat loss between the left, center, and right sides of the human body. It provides a wide-zone heating device to achieve wide-zone heating, ensuring that the user's sleep is not affected by temperature differences between the sides and the center when turning over.

[0031] In this embodiment, the heating body 1 includes a substrate 10 and multiple heating strips 11 distributed along the width of the mattress on the substrate 10. The density of the heating strips 11 in the left heating section 13 and the right heating section 14 is higher than that in the middle heating section 15. By differentiating the density of the heating strips 11 in the three heating sections, different heating powers can be achieved without additional control of the three heating sections, resulting in a simple and reliable structure.

[0033] In this embodiment, the length direction of a single heating strip 11 is consistent with the length direction of the mattress, and the spacing between the heating strips 11 in the three heating sections is different, resulting in different densities. In other embodiments, the length direction of a single heating strip 11 can also be along the width direction of the mattress, in which case more heating strips 11 are required.

[0034] In this embodiment, the width of the heating strip 11 is 2-4 cm, and the spacing between adjacent heating strips 11 in the same heating section is between 2-5 cm. More specifically, the width of the heating strip 11 is 3 cm, the spacing between adjacent heating strips 11 in the left heating section 13 and the right heating section 14 is 2.25 cm, and the spacing between adjacent heating strips 11 in the middle heating section 15 is 4.5 cm (the width and distance in the figure are for illustrative purposes only and are not drawn to scale).

[0035] In this embodiment, the width-zone heating device 01 also includes a controller 5 and a temperature sensor connected to the controller 5.

Specifically, the heating bars 11 are divided into two groups, which are connected in series, and the heating bars in each group are connected in parallel. Each group of heating bars 11 includes 7 heating bars. In other embodiments, all the heating bars 11 of the three heating sections may be connected in parallel. Damage to a parallel heating bar 11 does not affect the operation of other heating bars 11 (although it will affect the power).

[0039] In this embodiment, all heating strips 11 are flat, which improves the heating effect and makes it less likely to cause a foreign body sensation.

[0040] In this embodiment, the heating strip 11 is connected to leads 12 at both ends, and the leads 12 are made of high-temperature resistant silicone wire. The internal wiring harness 3 is also made of high-temperature resistant silicone wire.

[0043] The width-zone heating mattress of this utility model embodiment 1 has a heating body 1 with two width-zone heating devices 01, which have three heating parts corresponding to the left, middle and right sides of the human body. The heating power per unit area of ​​the left heating part 13 and the right heating part 14 is higher than that of the middle heating part 15, which reduces the temperature difference between the middle and the left and right sides, and avoids or reduces the impact of the temperature difference between the sides and the middle on sleep, especially when the user turns over. The heating power per unit area of ​​the three heating parts is different through the different distribution density of the heating strips 11. The structure is simple and reliable and does not require complex control. At least some of the heating strips 11 are connected in parallel. The damage of some of the parallel heating strips 11 does not affect the operation of other heating strips 11, and there is no situation in the prior art where the failure of one part of the fully series heating component causes the entire heating device to fail.
