This towel drying rack cannot achieve constant temperature drying and uses electric heating wire, resulting in high energy consumption and a risk of overheating, short circuits, and other safety issues.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0005] A constant temperature heating drying rack designed for this purpose includes a rack body, characterized in that: a heat-conducting plate for placing towels and clothing is provided on the rack body, and a circuit board is provided. A heating device is provided inside the heat-conducting plate, and a temperature detection component for detecting the temperature value of the heating device is provided on the heat-conducting plate. The circuit board is electrically connected to the temperature detection component, and a constant temperature control component is provided on the circuit board. The constant temperature control component is electrically connected to the heating device. The temperature detection component feeds back the detected temperature value to the circuit board, and the circuit board controls the current output value through the constant temperature control component, thereby controlling the operation of the heating device.

[0006] The heating device includes a heating element and an insulating element, with the insulating element fitted around the outer periphery of the heating element.

[0007] The heat-conducting plate has mounting holes, and the insulating parts are press-fitted into the mounting holes.

[0008] The heating element is a PTC ceramic heating element, and the insulation is high-temperature resistant insulating adhesive.

[0009] The temperature detection assembly includes a temperature probe and a flexible fastener. The temperature probe is fixed on the flexible fastener, which is mounted on a heat-conducting plate.

[0010] The circuit board is equipped with a microcontroller, and the temperature control component is a thyristor. The heating component is electrically connected to the thyristor. The microcontroller is electrically connected to the thyristor and the temperature probe. The temperature probe feeds back the detected temperature value to the microcontroller, and the thyristor feeds back the current value to the microcontroller.

[0014] The heat-conducting plates are distributed on the frame, one above the other.

[0015] This utility model's constant temperature heating drying rack uses a temperature detection component to feed back the detected temperature value to a circuit board. The circuit board then controls the current output value through a constant temperature control component, thereby controlling the operation of the heating device to achieve a constant temperature effect and realize intelligent constant temperature drying. This makes the heating drying rack more energy-efficient and prevents the heating device from overheating. In addition, the heating device uses PTC ceramic heating elements and high-temperature resistant insulating adhesive surrounding the PTC ceramic heating elements. PTC ceramic heating elements have the advantages of energy saving, safety, reliability, and long life. The high-temperature resistant insulating adhesive prevents short circuits. Furthermore, the heat conduction plate can improve the heat conduction speed, thereby improving drying efficiency. Attached Figure Description

A heating device 3 is provided inside the heat-conducting plate 2, and a temperature detection component 5 for detecting the temperature value of the heating device 3 is provided on the heat-conducting plate 2. The circuit board 6 is electrically connected to the temperature detection component 5, and a constant temperature control component is provided on the circuit board 6. The constant temperature control component is electrically connected to the heating device 3. The temperature detection component 5 feeds back the detected temperature value to the circuit board 6, and the circuit board 6 controls the current output value through the constant temperature control component, thereby controlling the operation of the heating device 3.

[0020] The heating device 3 includes a heating element 7 and an insulating element 8. The insulating element 8 is fitted around the outer periphery of the heating element 7 to insulate the heating element 7 and prevent short circuits.

[0021] The heat-conducting plate 2 is provided with mounting holes 9, and the insulating part 8 is pressed into the mounting holes 9. The insulating part 8 is elastic and the insulating part 8 is press-fitted into the mounting holes 9, thereby pressing the entire heating device 3 into the mounting holes 9. The temperature probe 10 extends into the mounting holes 9 to detect the temperature value of the heating device 3.

[0023] The temperature detection assembly 5 includes a temperature probe 10 and a flexible fastener 11. The temperature probe 10 is fixed on the flexible fastener 11, which is mounted on the heat-conducting plate 2. Specifically, the flexible fastener 11 is elastic and has a mounting groove for mounting the temperature probe 10. The temperature probe 10 is press-fitted into the mounting groove, thus pressing the temperature probe 10 firmly into the mounting groove. The heat-conducting plate 2 also has a mounting groove for mounting the flexible fastener 11, which is press-fitted into the mounting groove. The flexible fastener 11 is made of silicone material.
