[0002] As people pursue the quality of life, electric fireplaces as a device with both heating and decorative functions have received widespread attention. At present, electric fireplace products on the market generally install fake firewood inside, and motors and reflective beams are installed under the fake firewood. The light source is placed under or in front of the reflective beam, and the light shines on the reflective blades to form a virtual flame effect inside the back panel of the product. Some products add an atomizer and generate smoke through the atomizer, and use light to illuminate the smoke floating upward to form a virtual flame effect. However, the above-mentioned prior art has the following defects: a motor is required to drive the reflective beam to rotate and refract light sources such as LEDs and light bulbs to generate flames, and the flames are not real, the ornamental value is not high, and the structure is complex; in addition, the virtual flame effect is generated, and the flame has no temperature. If the heating function is to be added, it is necessary to add a heating element (such as a quartz tube, a heating rack, etc.) and a shaded pole fan to generate heat, which further leads to the complex structure of the electric fireplaces on the market and the limited product size.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] There are two types of electric fireplaces in the prior art. The first type is purely decorative, in which fake firewood is installed inside the shell, a motor and a reflective beam are installed below the fake firewood, and a light source is placed below or in front of the reflective beam. The light shines on the reflective blades to form a virtual flame effect inside the back panel of the product. Some products add an atomizer and generate smoke through the atomizer, and use light to shine on the upward floating smoke to form a virtual flame effect.

[0035] The second type has both heating and decorative functions. Based on the first type, the second type of electric fireplace adds resistance heating and a fan to generate heat energy.

[0036] However, both of the above solutions have the defects of being thick, complex in structure and poor in appearance. The thick electric fireplace has poor appearance and a bulky appearance. In addition, since both of the above solutions have the technical feature that the motor drives the anti-light beam to rotate, this results in a small length. If the length is too large, the motor will have difficulty driving the long anti-light beam to rotate.

[0037] In order to solve the above problems, the following Figures 1 to 10 , describing an embodiment of the present invention.

[0038] The present invention provides an electric fireplace, comprising: a housing 1, a flame generating device and a control device.

[0039] An accommodating space is provided in the housing 1; a flame generating device is provided in the accommodating space and can convert electrical energy into flame; and a control device is used to supply power to the flame generating device and control the working state of the flame generating device.

[0040] The present invention uses a flame generating device to convert electrical energy into flames. The heat generated by the flame can be dissipated into the indoor environment for heating, and the generated flame is real, just like the flame effect of burning firewood, and a real bright flame is truly generated, which improves the ornamental value. The present invention does not need heating elements such as quartz tubes, heating racks, shaded pole fans, light sources, motors, reflective light beams and other structures, simplifies the structure, and can also make small-sized electric fireplaces, such as electric fireplaces with a thickness of less than 60 mm. In addition, in the prior art, the reflective light beam is driven to rotate by a motor, and its structure cannot be made longer, while the electric fireplace in the present invention can better extend the product size, even to a length of 10 meters or more, which is a technology that cannot be achieved by traditional electric fireplaces on the market, and the market benefits generated are very large, and it can be applied to large-scale decoration industries, with broad prospects.

[0041] In some embodiments, the flame generating device includes a plurality of plasma generating devices 9 .

[0042] This embodiment uses a plasma generating device 9 to ionize air to obtain plasma, which is a flame and has the ability to generate heat energy.

[0043] In some embodiments, the plasma outlet of the plasma generating device 9 is circular, polygonal or irregular in shape.

[0044] Specifically, the plasma generating device 9 includes a first electrode 12 and a second electrode 14. The second electrode 14 is annular and is sleeved outside the first electrode 12.

Therefore, the electric fireplace provided by this embodiment has the functions of decoration and heating. The front door 5 in this embodiment can be opened and closed. Figure 3As shown, when a hollow front door 5 or a mesh front door 5 is used, heat can be dissipated to the indoor environment through the mesh structure and the hollow structure. In addition, an exhaust port 2 can be provided at the top of the shell 1 to further improve the heat dissipation effect. Since hot air will go upward, the front door 5 is set as a transparent door, and the hot air can be discharged through the exhaust port 2 on the top without setting a fan to drive the air flow.

[0049] Of course, the front door 5 can also be set to a structure that cannot be opened, such as Figure 1-2 , Figure 7-8 As shown, the non-openable front door 5 can be made of a metal plate, a transparent plate (transparent glass), a hollow plate or a mesh plate.

[0050] Regarding the arrangement of the front door 5, in addition to the above-mentioned embodiments, the front door 5 can be omitted in other embodiments of the present invention, that is, the housing 1 only has a back plate, side plates, a top plate and a bottom plate.

[0051] In some embodiments, a partition 10 is fixedly provided near the bottom of the shell 1, and the partition 10 divides the accommodating space into an upper cavity and a lower cavity. A plurality of mounting holes are provided on the partition 10, and the plasma generating device 9 is installed in the mounting holes, with the plasma outlet facing vertically upward, and the main control board 6 of the control device is arranged in the lower cavity.

[0052] The partition 10 in this embodiment plays a role of heat insulation, preventing the flame in the upper chamber from affecting the control device in the lower chamber.

[0053] In some embodiments, the shell 1 and the partition 10 are usually made of technical materials to prevent the shell 1 from being damaged by flames.

[0054] In some embodiments, the present invention further includes a heat dissipation fan 8 disposed in the lower cavity, and a portion of the housing 1 corresponding to the lower cavity is provided with heat dissipation holes.

[0056] In some embodiments, a button control panel 4 is disposed on the front side of the housing 1 , and the button control panel 4 is connected to the control device.

[0057] In some embodiments, the present invention supplies power to electrical devices in the electric fireplace by connecting an external power source via the power cord 3 .

[0058] In some embodiments, the thickness of the shell is not greater than 60 mm and the length is not less than 5 m.

[0059] This embodiment has a good ornamental function, is mainly used as a decoration, can be used in large shopping malls, etc., and has a heating function.
