Description

Technical Field

[0001] The utility model belongs to the technical field of heating components, and specifically refers to a heating module of a heater used on a clothes drying rack. Background Art

[0002] Currently, most heating modules on the market are composed of a fan, a heating wire and a temperature protection device. The temperature protection device is mostly based on an old-fashioned fuse-type structure. The fuse is a disposable consumable part. After it blows, the fuse core needs to be replaced, which brings trouble to users. In addition, the installation position of this device is between the two sets of heating wires and is far away from the heating wires.

[0003] When the fan is damaged, the heating wire continues to heat up. Since the temperature protection device is far away from the heating wire, the heating wire will continue to heat up rapidly to 100°C or even higher during this period. The fuse-type temperature protection device may still fail to fuse, and the power-off protection effect cannot be achieved. The heavy load can easily cause the device to catch fire until the entire clothes drying rack catches fire. In severe cases, it will bring huge safety hazards and significant economic losses to the family and the entire building. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a heating module for a heater on a clothes drying rack, which is used to solve the problem that the fuse structure in the prior art is far away from the temperature of the heating wire and cannot be identified and melted in time, and the disadvantage of not being able to achieve timely power-off protection, and solve the disadvantage that the fuse structure is inconvenient for users to use after it melts.

[0005] The technical solutions adopted in this application are as follows:

[0006] The present invention provides a heating module for a warm air blower on a clothes drying rack, which is composed of a frame, a fan and a heating wire. The fan is installed on one side of the frame, the heating wire is arranged inside the frame and corresponding to the fan, a support frame for supporting the heating wire is arranged inside the frame, a protective partition is arranged on one side of the frame away from the fan, and the heating wire is electrically connected to a power source;

[0007] The support frame is composed of two groups of support sheets distributed in the frame from top to bottom. Two groups of support frames are arranged inside the frame in the up and down directions. The heating wires include two groups of heating wires 1 and 2, which are arranged on the upper and lower support frames respectively.

[0008] Also includes:

[0009] Temperature control protection device;

[0010] The temperature control protection device is installed on the supporting plate. The temperature control protection device is provided with two groups, namely temperature control switch 1 and temperature control switch 2. One end of the temperature control switch 1 is connected to the live wire of the power supply, and the other end of the temperature control switch 1 is connected to the heating wire 1, the heating wire 2 is connected to the other end of the heating wire 1, the other end of the heating wire 2 is connected to the temperature control switch 2, and the temperature control switch 2 is connected to the neutral wire of the power supply.

[0011] Preferably, the live wire of the power supply, the first temperature control switch, the first heating wire, the second heating wire, the second temperature control switch and the neutral wire of the power supply are sequentially connected in series to form a series circuit.

[0012] In a preferred embodiment, a protection module may be provided between the second heating wire and the first heating wire, and the protection module may be a leakage protection switch.

When the temperature rises to about 65°C, at least one group of heating wires will be disconnected, so that the heating wires will no longer heat up, thereby playing a protective role and avoiding fire.

[0018] By using reusable temperature control switches and leakage protection switches, when the temperature drops to a certain level, the switches will work repeatedly to ensure the safety of the product's temperature protection, thus overcoming the complexity of replacing the fuse after it blows.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Example 1

[0031] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a heating module for a warm air blower on a clothes drying rack, which is composed of a frame 1, a fan 2 and a heating wire 3. The fan 2 is installed on one side of the frame 1, and the heating wire 3 is arranged inside the frame 1 and corresponding to the fan 2. A support frame 4 for supporting the heating wire 3 is provided inside the frame 1. A protective partition 11 is provided on the side of the frame 1 away from the fan 2. The heating wire 3 is electrically connected to a power source. A positioning groove is provided on the surface of the support sheet 41. The positioning groove is serrated to accommodate the heating wire 3, so that the heating wires 3 are spaced apart from each other. Among them, a wiring terminal is provided on one side of the frame 1, and the wiring terminal is connected to a power source.

[0032] refer to Figure 3 As shown, the support frame 4 is composed of two groups of support plates 41 distributed up and down in the frame 1. Two groups of support frames 4 are arranged inside the frame 1 in the up and down directions. The heating wire 3 includes two groups of heating wire 1 31 and heating wire 2 32. The heating wire 1 31 and the heating wire 2 32 are respectively arranged on the upper and lower support frames 4.

[0033] In the prior art, the temperature protection device is mostly based on the old-fashioned fuse structure, and the installation position of this device is between the two groups of heating wires and far away from the heating wire 3, so it cannot be fused in time. In order to solve the above problems, this solution provides a temperature control protection device 5.

[0034] Combination Figure 3 and Figure 4As shown, the temperature control protection device 5 is installed on the supporting plate 41. The temperature control protection device 5 is provided with two groups, namely a temperature control switch 1 51 and a temperature control switch 2 52. One end of the temperature control switch 1 51 is connected to the live wire of the power supply, and the other end of the temperature control switch 1 51 is connected to the heating wire 1 31, the heating wire 2 32 is connected to the other end of the heating wire 1 31, and the other end of the heating wire 2 32 is connected to the temperature control switch 2 52, and the temperature control switch 2 52 is connected to the neutral wire of the power supply.

[0035] Preferably, the live wire of the power supply, the temperature control switch 1 51 , the heating wire 1 31 , the heating wire 2 32 , the temperature control switch 2 52 and the neutral wire of the power supply are sequentially connected in series to form a series circuit.

[0036] As an example to further illustrate:

[0037] A protection module 7 may be further provided between the second heating wire 32 and the first heating wire 31. The protection module 7 is a leakage protection switch.

[0038] As an example to further illustrate:

[0039] The temperature control switch 1 51 is located inside the heating wire 1 31, and the temperature control switch 2 52 is located inside the heating wire 2 32. Inside the heating wire 3, the temperature sensing of the device can be synchronized with the heating wire 3.

[0040] When using the utility model, this scheme adopts a series structure to form a heating module. Once the fan 2 is damaged and the heating wire 3 continues to heat up, since the temperature control protection device 5 is respectively located inside the heating wire 3, the temperature control protection device 5 will feel the temperature rise of the heating wire 3. When the temperature rises to about 65°C, at least one group of the heating wires 3 will be disconnected, so that the heating wire 3 will no longer be heated, thereby playing a protective role.

[0041] Moreover, due to the series structure, even if one of the temperature control switches fails, the other temperature control switch will immediately intervene and then play a protective role of disconnecting the circuit, which can prevent the fire caused by damage to the fan 2 and avoid causing greater losses.

[0042] In addition, the present solution utilizes reusable temperature control switch 1 51, temperature control switch 2 52 and protection module 7, which repeat the operation when the temperature drops to a certain level to ensure the safety of product temperature protection, thus overcoming the complexity of the need to replace the fuse after it blows.

[0043] It should be noted that although the embodiments of the utility model have been shown and described, for ordinary technicians in this field, without departing from the inventive purpose of the utility model, structural methods and embodiments similar to the technical scheme without creative design should all fall within the scope of protection of the utility model.
