Description

Technical Field

[0001] This utility model belongs to the field of heating devices, specifically relating to a novel far-infrared radiant electric heating device suitable for heating production workstations. Background Technology

[0002] In Northeast my country, winter outdoor temperatures are extremely low, often dropping below -20°C and even approaching -40°C in some areas. To ensure people's daily needs are met, centralized heating is the primary method. While effective for residential and office areas, centralized heating has drawbacks for production workshops and large factories. The main problems are: ① Currently, centralized heating primarily relies on convection, raising the temperature through the flow of hot and cold air. However, production workshops and large factories are spacious with high ceilings, making it difficult for centralized heating to maintain the required temperature. This results in high energy consumption and persistently low temperatures, causing significant inconvenience for workers during winter. ② For businesses, ensuring workers can work comfortably in cold winters requires maintaining a certain temperature (e.g., 18°C) throughout the workshop and factory. This incurs substantial annual heating costs, increasing production costs. In reality, businesses only need to ensure workers feel warm enough to work with their bare hands; a consistently high overall temperature is not necessary. To address these issues, electric heating has been adopted. However, existing electric heating equipment has a high design power and low electrothermal conversion rate, failing to convert electrical energy into heat energy more efficiently. This results in high power consumption, low thermal efficiency, poor heat dissipation, and poor safety. The main reasons are: most existing electric heating devices use resistance heating as the primary heating method, with a single current transmission method and still relying on convection for heating; the lack of high-performance heat conversion materials prevents the energy-consuming resistance heating from dissipating effectively, reducing the utilization of electrical energy.

[0003] To address the aforementioned technical problems, this utility model provides a novel far-infrared radiant electric heating device that is energy-saving and can purposefully warm workers at specific workstations.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a novel far-infrared workstation radiant electric heating device, comprising a shell, a reflector, and a far-infrared heating cable; the shell comprises a rear shell plate and a front frame, the reflector is placed inside the shell, and the far-infrared heating cable is arranged in an S-shape and placed between the reflector and the front frame.

[0005] Furthermore, the aforementioned novel far-infrared workstation radiant electric heating device is equipped with a hanging device, which consists of a hanging device I and a hanging device II.

After the hanging device I and the hanging device II are installed in parallel, the hooks I and hooks II are arranged alternately, and the far-infrared heating cable is arranged in an S-shape after folding back and forth between the hooks I and hooks II.

[0006] Furthermore, the aforementioned novel far-infrared workstation radiant electric heating device has an inlet positioning part and a tail positioning part for the far-infrared heating cable at both ends of the hanging device I.

[0031] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0032] Example 1

[0033] like Figures 1-12 As shown, a novel far-infrared workstation radiant electric heating device includes a shell 10, a support frame 20, heat insulation cotton 30, a reflector 40, a hanging device 50, a far-infrared heating cable 60, and a terminal block 70.

[0034] The housing 10 includes a rear shell plate 11 and a front frame 12. During assembly of the electric heating device, the rear shell plate 11 and the front frame 12 must be fastened together, and the support frame 20 must be fixed to the housing 10. When the rear shell plate 11, support frame 20, and front frame 12 are fixed together, gaps will exist between the support frame 20 and the front frame 12 and rear shell plate 11. If directly fixed with screws, the existence of these gaps can easily cause deformation of the housing. Preferably, in this embodiment, the front frame 12 is provided with several front limiting blocks 13, and the rear shell plate 11 is provided with several rear limiting blocks 15. After the front frame 12 and rear shell plate 11 are fastened together, the support frame 20 is fixed to the front frame 12 and rear shell plate 11 respectively through the front limiting blocks 13 and the rear limiting blocks 15. The front limiting block 13 and the rear limiting block 15 fill the gap between them. Screws pass directly through the front frame, the front limiting block, and the support frame, and also directly through the rear shell plate, the rear limiting block, and the support frame, thus fixing the support frame to the front frame and the rear shell plate respectively. This ensures a secure installation and prevents deformation. Since the far-infrared heating cable 60 generates a certain high temperature after being energized, it poses a safety hazard. Preferably, in this embodiment, a protective railing 14 is provided on the front frame 12 to improve safety.

[0035] The support frame 20 is used to support the internal structure of the electric heating device and provide installation support.

[0036] The thermal insulation cotton 30 can provide thermal insulation and shielding against high temperatures of 1000℃. It is used for internal thermal insulation of the rear shell to prevent the rear shell from overheating during hoisting.

[0037] The reflector 40, in this embodiment, is made of 8K reflective aluminum plate, mainly used to reflect far-infrared rays for forward directional irradiation, increasing the far-infrared intensity in the directional irradiation area and improving the irradiation effect. The starting and ending ends of the far-infrared heating cable 60 need to pass through the reflector and connect to the terminal block 70. Therefore, as a preferred embodiment, the reflector 40 is provided with a recess 41 for the far-infrared heating cable 60 to pass through.

[0038] The cable hanger 50 consists of a cable hanging device I 51 and a cable hanging device II 56. The cable hanging device I 51 has several hooks I 52 spaced at equal intervals, and the cable hanging device II 56 has several hooks II 57 spaced at equal intervals. After the cable hanging devices I 51 and II 56 are installed in parallel, the hooks I 52 and II 57 are arranged alternately. The far-infrared heating cable 60 is arranged in an S-shape after repeatedly folding back and forth between the hooks I 52 and II 57. The far-infrared heating cable 60 has a certain degree of flexibility. To ensure the installation stability and slack of the far-infrared heating cable 60 after its S-shaped arrangement, preferably, in this embodiment, an inlet positioning part 53 and a tail positioning part 54 of the far-infrared heating cable 60 are respectively provided at both ends of the cable hanging device I 51. The inlet positioning part 53 and the tail positioning part 54 control the distance between the two wires at the inlet and outlet ends of the far-infrared heating cable, preventing localized overheating of the cable and damage to the circuit. After the far-infrared heating cable 60 is repeatedly folded and coiled, it needs to return to the inlet end. To prevent interference from contact with the S-shaped arrangement of the far-infrared heating cables 60 during the return process, preferably, in this embodiment, a hidden groove 55 is provided on the hanging device I 51. After the far-infrared heating cables 60 are arranged in an S-shape, preferably, the distance between two adjacent far-infrared heating cables 60 is 5-20mm. Within this range, the far-infrared heating cables can release far-infrared rays to the maximum extent, increasing the irradiation range, extending the service life of the far-infrared heating cables, and avoiding overheating caused by excessively close distance between cables.

[0039] Terminal 70 is used to connect the far-infrared heating cable 60 and the power plug.

[0040] The far-infrared radiant electric heating device provided in this embodiment is installed in the following order from back to front: rear shell plate 11, support frame 20, insulation cotton 30, reflector plate 40, hanging device 50, far-infrared heating cable 60 arranged in an S-shape, and front frame 12. The starting and ending ends of the far-infrared heating cable 60 pass through the reflector plate 40 and insulation cotton 30 and are connected to one end of the terminal block 70. The other end of the terminal block 70 is connected to the power connector. After the support frame 20 contacts the front frame 12 and the rear shell plate 11, the front limiting block 13 and the rear limiting block 15 fill the gap between them.

[0041] The far-infrared radiant electric heating device provided in this embodiment is assembled as follows: The rear shell plate 11 is laid flat, the support frame 20 is placed on the rear shell plate 11, and then the heat insulation cotton 30 and reflector plate 40 are placed in sequence. The hanging device I 51 and hanging device II 56 are then placed at both ends of the reflector plate 40 and fixed. After the starting end of the far-infrared heating cable 60 is positioned by the inlet positioning part 53, the far-infrared heating cable 60 is repeatedly folded and arranged between hooks I 52 and II 57, finally forming an S-shape. The end of the far-infrared heating cable 60 is positioned by the tail end positioning part 54 and then inserted into the concealed groove 55, returning to the inlet end through the concealed groove 55. The starting and ending ends of the far-infrared heating cable 60 pass through the reflector plate 40 and the heat insulation cotton 30 and are connected to one end of the terminal block 70. The other end of the terminal block 70 is connected to the power connector. Finally, the front frame 12 is fastened, and the front limiting block 13 on the front frame 12 and the rear limiting block 15 on the rear shell 11 contact the end face of the support frame (20) respectively. Finally, the shell 10 and the support frame 20 are fixed together by screws.

[0042] The far-infrared radiant electric heating device for workstations provided in this embodiment can be directly fixed to the wall for use. Alternatively, it can be used as follows: Figure 13 The electric heating device is fixed to the base 80 as shown. Casters 81 are installed under the base 80 so that it can be moved and used.
