TECHNICAL FIELD
The present disclosure generally relates to an electric fireplace and more particularly relates to an electric fireplace with a flame projector module undermounted from the main enclosure.
BACKGROUND
Most currently available electric fireplaces generally contains flame reflectors, a spindle motor, a light source and simulated logs or other ornaments, which are typically completely assembled and wired within the top surface of the enclosure's base panel which is the main viewing space for the fireplace ornaments and flame. Since the flame reflectors, spindle motor and light source would take significant space on this surface area, in current constructions these components are either:
- a) embedded in the ornamental portion of the firebox typically including simulated fire grate, logs, embers etc, for example as shown in US20210404667A1; or
- b) fully enclosed in the firebox and at the back of a translucent projection screen which hides the components from the user, for example as shown in US20060026894A1.
In construction a), the embedding of these components will negatively affect the aesthetics and realism of the ornaments which they are embedded within, as the size of the flame reflectors, spindle motor and light source must be accounted for in the shape of the ornaments which generally results in a over-sized uniform look which is unrealistic and aesthetically unappealing.
In construction b), the placement of these components at the back of a projection screen will significantly reduce the available viewing depth of the firebox which negatively affects the aesthetic and realistic aspect of the product. Also, the projection screen needs to be translucent material which has limitations to what materials can be used because the screen can't use real materials for cladding such as stone or brick on the back panel.
Also, in current constructions the number of flame generators may not exceed one without creating even more viewing constraints since the mounting space is limited, which makes the ornamental effect relatively monotonous.
The flame effect of these constructions viewing angle will also be limited to start at the height of where they are mounted on the top surface of the enclosure's base. Since space is needed for the reflectors to rotate without making contact to the base it is necessary for this position to be spaced upwards away from the base panel and therefore does not allow for the flame to start at the very bottom portion of the viewing angle near the base panel which is unrealistic as real flames would flicker at the very bottom area of the base and upwards.
Thirdly, in this kind of electric fireplaces, the grates or ornaments are wired to the light effects and cannot be interchanged with other ornaments without disconnecting and reconnecting connectors.
Therefore, in the prior art, there is a need for an electric fireplace, which allows to breakdown into modules with a reduced size for packaging, shipping and storing and then combine them in assembly at the manufacturer and to provide a more realistic flame effect with more realistic ornamental objects, such as a fire grate and logs which can also be mirrored on the flame screen, also allows to provide interchangeable grates and other ornaments without needing to be wired by connectors.
SUMMARY
An objective of the present disclosure is to design an electric fireplace with under-mounted flame projector module, which allows for saving viewing space of the electric fireplace since the space is completely opened and using multiple flame generator modules for an even more beneficial effect and realistic visual effects. Also, the size of the electric fireplace could be reduced.
Another objective of the present disclosure is to allow the manufacturer to assemble the flame projector module and the ornaments into the base as the base is typically an assembled part, the user would then combine the other parts in assembly. Also, allows to use a simple ornament without any wiring, therefore can make a cleaner more realistic look for less cost with the option of easily interchanging ornaments without having to connect any wires.

Ornament module 2 further comprises a second ornamental component 22 having an opening especially a backward opening, and the second ornamental component 22 is placed at the rear of the first ornamental component 21 and can also be a log or crystal or other ornamental component. The second ornamental component 22 could be a translucent log with a hole positioned towards the back panel of the firebox in order to project a flame effect through the translucent log as an additional effect. The first ornamental component 21 and the second ornamental component 22 may be made of transparent or preferred translucent material, so that the ornamental effect and projection effect can be seen from the front cover. At the position of the back panel 5 is provided with a projection screen 23. The projection screen 23 may be formed integrally with the back panel 5, or it can be separately provided inside the firebox with an interval of the back panel 5. In addition to the first light slot 41, the division plate 4 may also provide with a second light slot 42, the second light slot 42 is disposed in front of the first light slot 41 and located below the ornament module 2. At the position of the second light slot 42 is provided with a lighting device 13, the lighting device 13 may be a strip light or an LED light. As shown in FIG. 5, a rear view of the flame generator module assembling with the division plate is shown, wherein the flame generator module is a separate module encapsulated in the housing 10. The flame generator module is mounted under the first light slot 41.
The light emitted by the flame generator 12 is reflected by the rotating reflecting blades, and irradiated to the projection screen 23 through the first light slot 41 on the division plate 4, forming a scrolling changing flame effect on the projection screen 23. From the front cover, the user can also observe the flame effect on the projection screen 23, even through the first ornamental component 21 and the second ornamental component 22. The light emitted by the lighting device 13 is directly irradiated on the first ornamental component 21 and the second ornamental component 22. From the front cover, the user can observe the overall ornamental effect inside the fireplace. By placing the ornaments on a separately power supplied lighting device, the ornament module in the present disclosure can be illuminated without any wires connected to the power supply, so that the installation and combination of the ornament module is convenient. There is no need to use wires to connect the ornament module with the power supply, and can present a variety of different combined visual effects.
FIGS. 6-8 show a second embodiment with a dual flame generator module. In this embodiment, the lighting device 13 in the previous embodiment is replaced by another flame generator module, the dual flame generator modules are still installed in the accommodating chamber of the base 7. Correspondingly, the second light slot 42 on the division plate 4 is replaced by another first light slot 41. As shown in FIG. 7, the front flame generator module is located below the ornament module, and the rear flame generator module is located at the rear of the ornament module. The reflected light emitted by the rear flame generator module is projected onto the projection screen 23, and the light emitted by the front flame generator module is directly irradiated to the first ornamental component 21 and the second ornamental component 22. By changing the color of the light emitted by the flame generators, different flame effects can be observed.
FIGS. 9-11 show a third embodiment having only a single flame generator module. In this embodiment, the flame generator module is still mounted in the accommodating chamber of the base 7, and is located below the ornament module 2, but the lighting device 13 is removed. Correspondingly, the division plate 4 also has only a first light slot 41. The light emitted by the flame generator module irradiates directly on the ornament module, and part of the light irradiates through the ornament module to the projection screen to form a projection effect. The ornament module and the projection screen create an overall visual effect of flame burning. This embodiment may make the thickness of the fireplace smaller, and is more suitable for miniaturized fireplace products.

The embodiment differs from the first embodiment in that, in addition to a projection screen 23 positioned at the back panel, a translucent plate 24 is also provided in front of the projection screen 23. The translucent plate 24 and the projection screen 23 can be set parallel at an interval, and the projection screen 23 has a reflection function, that is, the projection screen 23 is a reflective projection screen, i.e. a mirrored projection screen. In this embodiment, the flame generator module is still installed in the accommodating chamber of the base 7, and the light emitted by the flame generator module is reflected on the translucent plate 24 after irradiating on the reflective projection screen 23. The light emitted by the lighting device 13 irradiates directly on the first ornamental component 21 and the second ornamental component 22. FIG. 13 shows a varied embodiment of the second embodiment, i.e., a fifth embodiment of the present disclosure. The dual flame generator modules are mounted in the accommodating chamber of the base 7, and a vertical translucent plate 24 is provided in front of the projection screen 23. The projection screen 23 has a reflective function, that is, the projection screen 23 is a reflective projection screen. These two embodiments can achieve different flame visual effects relative to the first and second embodiments.
FIG. 14 shows a varied embodiment of the fourth embodiment, i.e., a sixth embodiment of the present disclosure. FIG. 15 shows a varied embodiment of the fifth embodiment, i.e., a seventh embodiment of the present disclosure. In the embodiments shown in FIGS. 14-15, there is no projection screen provided at the back panel, but only a translucent plate 24 is provided in front of the back panel. The translucent plate 24 needs to be disposed in front of the rear flame generator module. Correspondingly, the rotary electric reflector 11 in the flame generator module needs to be disposed at the rear of the flame generator 12, the light emitted by the flame generator 12 is reflected by the rotary electric reflector 11 and directly irradiates to the translucent plate 24 and the second ornamental component 22. The light emitted by the lighting device 13 or the front flame generator module irradiates directly on the first ornamental component 21 and the second ornamental component 22. Preferably, the translucent plate 24 may be disposed on the top of the second ornamental component 22 with an opening, i.e., the translucent plate 24 does not obscure the opening portion of the second ornamental component 22.
FIGS. 16-17 respectively shows the eighth and ninth embodiments of the present disclosure, which are the varied embodiments of the first embodiment shown in FIG. 3 and the fourth embodiment shown in FIG. 12 respectively, wherein a combined flame generator module is provided in the accommodating chamber of the base. Specifically, the combined flame generator module comprises a flame generator module and a lighting device as described above, i.e., the flame generator module and the lighting device are combined and encapsulated inside the housing 10. As shown in FIG. 16, the light emitted by the lighting device irradiates on the first and second ornamental components, and the light emitted by the flame generator module irradiates on the projection screen 23. In the embodiment shown in FIG. 17, the projection screen 23 has a reflective function, i.e., the projection screen 23 is a reflective projection screen. The front of the projection screen 23 is provided with a translucent plate 24, and the light reflected by the projection screen 23 irradiates on the translucent plate 24.
FIG. 18 shows a schematic diagram of the combined flame generator module of the present disclosure. The housing 10 comprises a main body 101 and a top cover 102, the main body 101 and the top cover 102 encloses a cavity. In the cavity of the housing 10 is provided with a lighting device 13, a rotary electric reflector 11 and a flame generator 12 in turn. The lighting device 13 is disposed in front of the rotary electric reflector 11 and the flame generator 12. Preferably, as shown in FIGS. 16-17, in order to prevent the light emitted by the lighting device 13 and the flame generator 12 from interfering with each other, an auxiliary housing 100 may be provided. The rotary electric reflector 11 and the flame generator 12 are disposed inside the auxiliary housing 100, and the lighting device 13 may be disposed outside the auxiliary housing 100. As shown in FIG. 18, the exterior of the housing 10 is further provided with a driving motor 103, the driving motor 103 is connected to the driving shaft of the rotary electric reflector 11.
By under-mounting the flame generator module in the base, it can save viewing space of the visual firebox since there is no space used on the main viewing area. It also allows for the option of using multiple flame generator modules for an even more beneficial effect as it can bounce the flame off objects on the firebox. It also looks more like a flame as the starting point from a visual vantage point, which looks like it is coming from under the grate or other objects such as logs. Also, the full firebox area and depth is now can be used for ornamental objects, thicker stone cladding textures, larger more realistic logs etc.
By under-mounting the flame generator module in the base, it also allows manufacturer to pre-assemble the flame projector module inside the base which is hollow and therefore does not add any additional packaging space for the flame generator module only. Additionally, it allows the manufacturer to take all the electronics out of the ornament module, allowing that to be a simple ornament without any wiring therefore can make a cleaner more realistic look for less cost. This is especially important for some of the smaller mantel models that have limited space and depth in the firebox area.
It is also possible to combine loose logs and other ornaments such as stones crystals, to allow the consumer to place logs in a preferred configuration, since the grate is not electrified and the illumination comes from a separated light strip module source. Other light strips can be installed in different areas of the mantel to create effects such as downlights, shadows, etc. Further, in various embodiments, the components of the electric fireplace can be configured relative to one another so that they can be packaged together much more compactly, which can provide even further cost efficiencies.
Although the implementations of the present disclosure are described above, the contents descried are only implementations used to understand the present disclosure and not intended to limit the present disclosure. Without departing from the spirit and scope disclosed by the present disclosure, any person skilled in the art to which the application belongs can make any modifications and alterations to the forms and details of implementation.
