Description

Technical Field

[0001] This utility model relates to the field of heating device technology, specifically to heating devices. Background Technology

[0002] Traditional fan heaters typically use heating wires or PTC ceramic heating elements as heat sources, and rely on fans to blow hot air out to heat the space. However, these devices often have a monotonous design, lacking decorative appeal and ambiance-creating capabilities, failing to meet users' aesthetic needs. Although some products attempt to enhance visual appeal by simulating flame effects with lighting, their dynamic performance is poor and lacks realism, resulting in significant shortcomings in user interaction and visual effects. Utility Model Content

[0003] In view of this, the present invention provides a heating device to solve the problems of poor dynamic performance and lack of realism in the simulation of flame effects of traditional heating devices, as well as significant deficiencies in user interaction experience and visual effects.

[0004] This utility model provides a heating device, including: The casing has a flame display area. The heating module is housed within the casing; A flame simulation module is disposed inside the housing and corresponds to the position of the flame display area; The control module is communicatively connected to the heating module and the flame simulation module; The control module adjusts the output power of the heating module and the display intensity of the flame simulation module simultaneously based on the gear adjustment command.

[0005] Beneficial effects: By synchronously adjusting the output power of the heating module and the display intensity of the flame simulation module based on the gear adjustment command, the control module achieves a positive correlation between the flame visual effect and the heating power, realizing a high degree of coordination between heat output and flame visual effect. This allows users to perceive the real-time heating status through intuitive changes in flame intensity, making operation more intuitive and providing clear feedback. It also enhances the interactive experience during use, strengthens the overall realism of the product, and achieves a coordinated unity between functional adjustment and visual feedback, avoiding the problem of disconnect between heating effect and visual performance in traditional heating devices.

[0006] In one optional implementation, the flame simulation module includes: The light source unit is disposed inside the housing and is communicatively connected to the control module. A reflection unit is disposed in front of the optical path of the light source unit.

[0007] Beneficial effects: By communicating and cooperating with the control module through the light source unit and setting a reflection unit in front of its light path, the intensity of the flame display can be adjusted by responding to control commands through the light source unit, and the light can be reflected through the reflection unit to enrich the sense of layering and dynamic visual effects of the flame simulation. This simplifies the module structure while improving the realism of the flame simulation and optimizing the visual experience.

[0008] In one optional implementation, the flame simulation module further includes a drive unit, the drive unit comprising: The driving component is disposed inside the housing and is communicatively connected to the control module; The rotating shaft has one end connected to the output shaft of the drive unit and the other end rotatably connected inside the housing; the reflecting unit is wound around the rotating shaft.

[0009] Beneficial effects: By communicating with the control module through the drive component, it can directly receive command signals from the control module and control the rotation speed and start / stop status of the shaft in real time. The reflective unit wound around the shaft moves with the shaft, realizing dynamic adjustment of the reflection angle and reflection range of the light emitted by the light source unit, thereby simulating the visual effect of flickering and dancing flames. This structure not only keeps the visual output synchronized with the equipment level or setting mode, but also enhances the vividness and realism of the flame simulation. The entire drive structure is simple and reliable in design, easy to integrate with existing control modules, and ensures practicality and manufacturing feasibility while enhancing visual expressiveness.

[0010] In one alternative embodiment, the reflective unit is a silver paper made of a flexible reflective material.

[0011] Beneficial effects: Using silver paper as a flexible reflective material satisfies the flexibility required by the reflective unit, making it easy to wrap around the rotating shaft and change shape with rotation. Furthermore, the excellent high reflectivity of silver paper maximizes the reflection of light emitted by the light source unit, thus presenting a bright visual flame effect that more closely resembles the light and shadow texture of a real flame. In addition, the extremely light weight of silver paper reduces the load on the drive unit, resulting in smoother system operation, lower energy consumption, and extended service life. Moreover, as a common and readily available material, silver paper is low in cost and easy to process, effectively reducing the production and assembly costs of the flame simulation module.

[0012] In one alternative implementation, the light source unit is a light-emitting diode lamp.

[0013] Beneficial effects: Due to the high photoelectric conversion efficiency of LED lights, their energy consumption is much lower than that of traditional light sources, which can effectively reduce the overall energy consumption of heating devices and meet the requirements of energy-saving design; in addition, their fast response speed can follow the control module's gear adjustment command to realize timely switching of flame display intensity, ensuring the synchronicity of the positive correlation between flame visual effect and heating power; furthermore, LED lights have a long lifespan and high stability, which can reduce the replacement frequency of light source units and improve the long-term reliable operation capability of flame simulation module; and their low-temperature light emission characteristics can avoid the high temperature of the light source itself from causing thermal impact on other components inside the housing, ensuring the operational safety of internal components of the heating device.

[0014] In one optional embodiment, the flame simulation module further includes a charcoal effect panel, which is disposed inside the housing and corresponds to the position of the flame display area. The light source unit and the reflection unit are both disposed on the side of the charcoal effect panel away from the flame display area.

[0015] Beneficial effects: Since the charcoal fire effect panel is set up in correspondence with the flame display area, and the light source unit and the reflection unit are set on the side of the charcoal fire effect panel away from the display area, the charcoal fire effect panel can shield the internal light source unit, reflection unit and other module structures, which enhances the realism of the simulated flame. It also allows the light reflected by the reflection unit to present a more regular visual effect after being processed by the charcoal fire effect panel, making the simulated flame more layered and beautiful. In addition, it can also improve the overall appearance of the heating device.

[0016] In one alternative embodiment, the housing includes: The casing has an opening on one side; A transparent plate is fixedly covered at the opening to form the flame display area.

[0017] Beneficial effects: The combination of the casing and the transparent panel creates a stable and enclosed installation environment. The casing provides effective protection and structural support for each module while ensuring the visualization of the flame visual effect. It also achieves a reasonable division of functional areas and a stable presentation of display functions while ensuring the protective performance of the casing.

[0018] In one alternative implementation, the heating module is arranged circumferentially around the housing.

[0019] Beneficial effects: The heating module is arranged circumferentially around the casing, allowing heat to be evenly distributed along the perimeter, avoiding localized overheating or heat concentration. This promotes uniform heat diffusion and ensures a consistent temperature distribution on the casing surface, thereby enhancing safety and comfort. It improves heating efficiency and the balance of heat utilization, while also creating a rational spatial layout with the flame display area, reducing interference with display functions, and enhancing the overall thermal stability and safety of the structure.

[0020] In one optional embodiment, the heating device further includes: A temperature detection module is installed in the housing and is communicatively connected to the control module.

[0021] Beneficial effects: By setting up a temperature detection module that communicates with the control module, the ambient temperature can be detected in real time and fed back to the control module. This allows the control module to adjust the output power of the heating module based on the temperature data, avoiding excessively high or low temperatures. This not only improves the temperature control accuracy of the heating device but also optimizes energy consumption and ensures stable operation of the equipment.

[0022] In one alternative implementation, the heating device is a fan heater. Attached Figure Description

[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0031] According to an embodiment of the present invention, a heating device is provided, including a housing 100, a heating module 200, and a flame simulation module; the housing 100 is provided with a flame display area; the heating module 200 is disposed inside the housing 100; the flame simulation module is disposed inside the housing 100, corresponding to the position of the flame display area; a control module 400 is communicatively connected to the heating module 200 and the flame simulation module; wherein, the control module 400 synchronously adjusts the output power of the heating module 200 and the display intensity of the flame simulation module based on a gear adjustment command.

[0032] In the above embodiments, the control module 400 synchronously adjusts the output power of the heating module 200 and the display intensity of the flame simulation module based on the gear adjustment command, so that the flame visual effect and the heating power are positively correlated. This achieves a high degree of coordination between heat output and flame visual effect, allowing users to perceive the real-time heating status through intuitive changes in flame intensity. The operation is more intuitive and the feedback is clear. This improves the interactive experience during use, enhances the overall realism of the product, and achieves a coordinated unity between functional adjustment and visual feedback, avoiding the problem of the disconnect between heating effect and visual performance in traditional heating devices.

[0033] In a specific implementation, the heating module 200 adopts proportional-integral-derivative (PID) control, which can dynamically adjust the output based on real-time feedback signals to achieve continuous stepless adjustment of heating power, thereby improving the accuracy of temperature control.

[0034] In a specific embodiment, the control module 400 includes a control board 410, which is disposed on the housing 100. It should be noted that the control module 400 in this embodiment can receive gear adjustment commands from various input units. Input units include, but are not limited to, a button panel 420 or knob disposed on the housing 100, a wireless receiving unit for receiving remote signals, a voice control unit for receiving user voice commands, and other control methods such as touch control, remote control, or mobile application. Those skilled in the art will understand that any substitution of the aforementioned input units falls within the protection scope of this application.

[0035] In a specific embodiment, the heating device further includes a support structure 500, on which the housing 100 is fixed. In a specific embodiment, the support structure 500 includes three support legs 510, which are evenly distributed circumferentially along the bottom of the housing 100 and fixedly connected to the housing 100. Each support leg 510 extends outwards at an angle, ensuring the stability of the support structure 500.

[0036] In one embodiment, the flame simulation module includes a light source unit 310 and a reflection unit 320; the light source unit 310 is disposed inside the housing 100 and is communicatively connected to the control module 400; the reflection unit 320 is disposed in front of the light path of the light source unit 310.

[0037] In the above embodiment, the light source unit 310 communicates and cooperates with the control module 400, and a reflection unit 320 is set in front of its light path. The light source unit 310 can respond to control commands to adjust the intensity of the flame display, and the reflection unit 320 can reflect the light to enrich the sense of layering and dynamic visual effects of the flame simulation. This simplifies the module structure while improving the realism of the flame simulation and optimizing the visual experience.

[0038] In a specific implementation, the light source unit 310 adopts pulse width modulation (PWM) control, which continuously and steplessly adjusts the luminous intensity of the light source unit 310 by adjusting the duty cycle. When the heating device is turned up, the brightness of the light source unit 310 increases accordingly, thereby making the simulated charcoal fire and flames more visually bright, enhancing the realism and dynamic layering of the overall performance.

[0039] In one embodiment, the flame simulation module further includes a drive unit, which includes a drive element 331 and a rotating shaft 332. The drive element 331 is disposed inside the housing 100 and is communicatively connected to the control module 400. One end of the rotating shaft 332 is connected to the output shaft of the drive element 331, and the other end is rotatably connected inside the housing 100. The reflection unit 320 is wound around the rotating shaft 332.

[0040] In the above embodiment, the drive unit 331 is communicatively connected to the control module 400, allowing it to directly receive command signals from the control module 400 and control the rotation speed and start / stop status of the rotating shaft 332 in real time. The reflective unit 320, wound around the rotating shaft 332, moves with the shaft, dynamically adjusting the reflection angle and range of the light emitted by the light source unit 310, thereby simulating the visual effect of flickering and dancing flames. This structure not only synchronizes the visual output with the device's settings or modes but also enhances the vividness and realism of the flame simulation. The entire drive structure is simple and reliable in design, easy to integrate with the existing control module 400, and while enhancing visual expressiveness, it also ensures practicality and manufacturing feasibility.

[0041] Specifically, the driving component 331 is preferably a stepper motor. The stepper motor can receive signals from the control module 400 and precisely control the rotation speed of the rotating shaft 332, thereby achieving stable and reliable driving of the dynamic effect of the reflection unit 320.

[0042] In a specific embodiment, the housing 100 is provided with a groove, one end of the rotating shaft 332 is connected to the output shaft of the drive member 331, and the other end is rotatably disposed in the groove.

[0043] In one embodiment, the reflective unit 320 is made of a flexible reflective material.

[0044] In the above embodiments, the reflective unit 320 is made of flexible reflective material, which is not only easy to wrap and fix on the rotating shaft 332 to adapt to the rotating structure of the drive unit, but also produces natural shape changes due to its own flexibility when the rotating shaft 332 rotates, so that the angle and intensity of the reflected light present rich and irregular dynamic differences, further simulating the realistic texture of the flame naturally swaying. At the same time, the flexible material is easy to process and has a low cost, which is conducive to the production, assembly and cost control of the flame simulation module.

[0045] In one embodiment, the flexible reflective material is silver paper.

[0046] In the above embodiments, silver paper is selected as a flexible reflective material. This satisfies the flexibility required by the reflective unit 320, making it easy to wrap around the rotating shaft 332 and change with rotation. Furthermore, the excellent high reflectivity of the silver paper maximizes the reflection of light emitted by the light source unit 310, thus presenting a bright visual flame effect that more closely resembles the light and shadow texture of a real flame. Moreover, because the silver paper is extremely lightweight, it reduces the load on the drive unit, making the system operate more smoothly and consuming less energy, thus extending its service life. At the same time, as a common and readily available material, silver paper is low in cost and easy to process, effectively reducing the production and assembly costs of the flame simulation module.

[0047] In one embodiment, the light source unit 310 is a light-emitting diode lamp.

[0048] In the above embodiments, since light-emitting diode lamps (LED lamps) have high photoelectric conversion efficiency and energy consumption far lower than traditional light sources, they can effectively reduce the overall energy consumption of the heating device and meet the requirements of energy-saving design. Furthermore, their fast response speed allows them to follow the gear adjustment commands of the control module 400, enabling timely switching of flame display intensity and ensuring the synchronicity of the positive correlation between flame visual effect and heating power. In addition, LED lamps have long lifespan and high stability, which can reduce the replacement frequency of the light source unit 310 and improve the long-term reliable operation capability of the flame simulation module. Moreover, their low-temperature light emission characteristics can prevent the high temperature of the light source itself from causing thermal effects on other components inside the housing 100, ensuring the operational safety of the internal components of the heating device.

[0049] In one embodiment, the flame simulation module further includes a charcoal effect panel 340, which is disposed inside the housing 100 and corresponds to the position of the flame display area. The light source unit 310 and the reflection unit 320 are both disposed on the side of the charcoal effect panel 340 away from the flame display area.

[0050] In the above embodiment, since the charcoal fire effect plate 340 is set corresponding to the flame display area, and the light source unit 310 and the reflection unit 320 are set on the side of the charcoal fire effect plate 340 away from the display area, the charcoal fire effect plate 340 can block the internal light source unit 310, reflection unit 320 and other module structures, which enhances the realism of the simulated flame. It can also make the light reflected by the reflection unit 320 present a more regular visual effect after being acted upon by the charcoal fire effect plate 340, making the simulated flame more layered and beautiful, and can also improve the overall appearance of the heating device.

[0051] In a specific implementation, the charcoal fire effect plate 340 simulates the shape of charcoal fire.

[0052] In the above embodiment, the charcoal fire effect panel 340 is designed to simulate the shape of charcoal fire and corresponds to the flame display area. This allows the light generated by the light source unit 310 and the reflection unit 320 to pass through or act on the charcoal fire effect panel 340 in the shape of charcoal fire, forming a scene of flames burning on charcoal fire, which greatly enhances the overall visual immersion and realism. At the same time, the charcoal fire effect panel 340 in the shape of charcoal fire itself is decorative and can be directly used as the visual base of the flame display area without the need for additional decorative structures. This simplifies the structural design while improving the realism of the flame simulation.

[0053] In one embodiment, the housing 100 includes a cover 110 and a transparent plate 120; the cover 110 has an opening on one side; the transparent plate 120 is fixedly covered at the opening to form a flame display area.

[0054] In the above embodiments, the combination of the cover 110 and the transparent plate 120 forms a stable and closed installation environment. The cover 110 effectively protects and supports the structure of each module, while ensuring the visualization of the flame visual effect. While ensuring the protective performance of the housing 100, it also achieves a reasonable division of functional areas and a stable presentation of display functions.

[0055] In a specific embodiment, the housing 110 has a back plate and a side wall surrounding the back plate, which together form a receiving cavity with a front opening. The light-emitting unit, the reflective unit 320, and the driving member 331 are all housed in this receiving cavity. A transparent plate 120 covers and is fixed to the front opening of the housing 110. The area observed by the user through the transparent plate 120 is the flame display area.

[0056] In a specific embodiment, the interior of the housing 100 is arranged from front to back as follows: a transparent plate 120, a charcoal effect plate 340, and a light source unit 310. The light source unit 310 is located below the housing 100, and a reflective unit 320 is positioned above it. The reflective unit 320 is wound around a rotating shaft 332 and rotates with the drive member 331. When the light source unit 310 is lit, its light is dynamically refracted by the rotating reflective unit 320, creating a visual effect of flames behind the charcoal effect plate 340. Simultaneously, the charcoal effect plate 340, illuminated by the light source unit 310, displays a static charcoal texture. The static charcoal texture and the dynamic flames together constitute the visual effect of charcoal burning.

[0057] In one embodiment, the heating module 200 is arranged circumferentially around the housing 110.

[0058] In the above embodiment, the heating module 200 is arranged circumferentially around the housing 110, which allows heat to be evenly distributed along the periphery of the housing 110, avoiding local overheating or heat concentration, and promoting uniform heat diffusion. This results in a consistent temperature distribution on the surface of the housing 100, thereby enhancing safety and comfort. It improves heating efficiency and the balance of heat utilization, forms a reasonable spatial layout with the flame display area, reduces interference with the display function, and enhances the overall thermal stability and safety of the structure.

[0059] In a specific implementation, the housing 100 has a circular structure, the heating module 200 is installed in the edge area of ​​the housing 100, and the flame display area is set in the center of the housing 100, which is conducive to achieving uniform heat diffusion and overall presentation of the flame visual effect.

[0060] In a specific implementation, the control module 400 is fixedly installed on the top of the housing 100, and the heating module 200 starts from one end of the control module 400, extends along the circumference of the housing 100 and finally wraps back to the other end of the control module 400, thereby forming a continuous heating structure around the periphery of the housing 100.

[0061] In one embodiment, the heating device further includes a temperature detection module; the temperature detection module is installed in the housing 100 and is communicatively connected to the control module 400.

[0062] In the above embodiment, by setting a temperature detection module that is communicatively connected to the control module 400, the ambient temperature can be detected in real time and fed back to the control module 400. This allows the control module 400 to adjust the output power of the heating module 200 based on the temperature data, avoiding excessively high or low temperatures. This not only improves the temperature control accuracy of the heating device but also optimizes energy consumption and ensures stable operation of the equipment.

[0063] It should be noted that the technical solution provided in this embodiment is applicable to various types of heating devices, including but not limited to electric fireplaces, heaters, and fan heaters.

[0064] In one embodiment, the heating device is a fan heater.

[0065] In a specific implementation, when the user activates the heating device, the heating module 200, the light source unit 310, and the driving component 331 start simultaneously. The heating module 200 begins heating, the light source unit 310 illuminates, and the driving component 331 drives the reflector unit 320 to rotate slowly, simulating a flame visual effect. As the heating level increases, the power of the heating module 200 increases, improving heating efficiency; simultaneously, the brightness of the light source unit 310 increases, the rotation speed of the driving component 331 increases, and the rotation of the reflector unit 320 accelerates, making the flame effect brighter and more dynamic. Conversely, when the heating level decreases, the power of the heating module 200 and the brightness of the light source decrease simultaneously, the rotation speed of the driving component 331 slows down, and the flame visual effect weakens accordingly. This linkage adjustment mechanism can maintain coordination between visual and thermal output at different heating levels, enhancing the user's immersive experience and satisfaction.
