[0027] It should be noted that, in this document, relational terms such as “first” and “second” are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0028] Example 1

[0029] The present application embodiment provides a far-infrared electric fireplace, referring to Figure 1 and Figure 2 The far-infrared electric fireplace comprises a protective panel 1, a heating plate 2, a heat insulating layer 3, a back cover 4 and a frame 5, wherein the protective panel 1, the heating plate 2 and the back cover 4 are parallel to each other, the heating plate 2 is directly opposite to the protective panel 1, and there is a safety distance between the protective panel 1 and the heating plate 2; the frame 5 is located on the side of one side of the far-infrared electric fireplace, and the frame 5, the heating plate 2 and the protective panel 1 form a cavity; the front side of the frame 5 is closed by the protective panel 1, and the back side of the frame 5 is closed by the back cover 4, and the projection of the protective panel 1 to the back completely covers the frame 5 and the back cover 4; the frame 5, the protective panel 1 and the back cover 4 form an internal space of the far-infrared electric fireplace, and the heating plate 2 and the heat insulating layer 3 are fixed in the space, and the heat insulating layer 3 is located between the heating plate 2 and the back cover 4, and the heat insulating layer 3 is preferably rock wool.

[0030] Reference Figure 1 In this embodiment, the protective panel 1 is preferably in the shape of a rectangular plate, and is divided into an upper and lower area by a horizontal line. A rectangular mesh 11 is perforated in the upper area, and a flame visual effect simulator is arranged in the lower area. The orthographic projection area of ​​the arrangement range of the mesh 11 on the heating plate 2 should account for at least half of the area of ​​the heating plate 2, and in this embodiment, it preferably accounts for 2 / 3 of the area of ​​the heating plate 2.

[0031] Reference Figure 1 The flame visual effect simulator is composed of a controller and a display screen 7. The controller is connected to the display screen 7 through a cable. The controller is used to control the display screen 7 to display a static picture or a dynamic video of the flame. The display screen 7 is preferably arranged in the center of the area below the mesh 11 on the protective panel 1. The display screen 7 can be directly attached to the outer surface of the protective panel 1 (holes need to be punched on the protective panel 1 to pass the cables), or the display screen 7 can be attached to the inner surface of the protective panel 1 and a window can be opened on the protective panel 1 to expose the display screen 7. The controller can be fixed to the bottom of the outer side of the frame 5 with an ordinary box, or it can be fixed in the air convection cavity 6 with an insulating box.

[0032] Reference Figure 1 The display screen 7 is one of a lamp bead board, an LCD screen, an LED screen or an OLED screen, among which the lamp bead board is the most stable and durable, and is least affected by the heat radiation of the heating plate 2, while the color saturation and vividness of the OLED screen are good, and the flame display effect is more realistic; the lamp bead board adopts LED lamp beads, ordinary LED lamp beads can withstand -30℃~+125℃, and high-temperature resistant LED lamp beads can withstand -40℃~+150℃, while LCD screens, LED screens or OLED screens are not heat-resistant, so the thermal insulation structure cost of the lamp bead board in the air convection cavity 6 is relatively low, while a higher thermal insulation structure cost is required when an LCD screen, LED screen or OLED screen is used.

[0033] The far-infrared electric fireplace proposed in this embodiment is directly embedded in the groove reserved on the wall during installation. When the far-infrared electric fireplace is working, it only emits heat forward by the heat radiation of the heating plate 2. The working principle of the far-infrared electric fireplace proposed in this embodiment is:

[0034] The heating plate 2 radiates heat into the room through the mesh holes 11 on the protective panel 1; the simulated flame displayed by the flame visual effect simulator can create the illusion that there is a burning fire cavity inside the electric fireplace, so that the user can feel the heat radiation like being warmed by a fire, and the body feels like a real fire fireplace, giving the user a warm feeling of using a traditional open flame fireplace, and psychologically feeling warmer and more comfortable.

[0035] Example 2

[0036] The present application embodiment provides a far-infrared electric fireplace based on embodiment 1. Figure 3 and Figure 4 The far-infrared electric fireplace of this embodiment is provided with air convection holes 51 and floor-standing support feet 9.

[0037] Reference Figure 4The frame 5, the heating plate 2 and the protective panel 1 form a cavity as an air convection cavity 6. A row of air convection holes 51 are provided at the top and bottom of the frame 5 along the length direction of the far-infrared electric fireplace. The air convection holes 51 are communicated with the air convection cavity 6, and there is a corresponding air convection hole 51 at the bottom of the frame 5 directly below each air convection hole 51 at the top of the frame 5.

[0038] Reference Figure 4 The bottom of the frame 5 is detachably fixed with a floor support foot 9 by screws. The floor support foot 9 can firmly support the far-infrared electric fireplace on the ground and make the bottom of the frame 5 a certain distance away from the ground, so that the air can smoothly enter the air convection cavity 6 from the air convection hole 51 at the bottom of the frame 5. The bottom air in the air convection cavity 6 rises after being heated by the heating plate 2 and is discharged from the air convection hole 51 at the top of the frame 5.

[0039] The far-infrared electric fireplace proposed in this embodiment has the following working principle:

[0040] The indoor air enters the air convection cavity 6 from the bottom of the frame 5. After the heating plate 2 heats the air at the bottom of the air convection cavity 6, the hot air rises and is discharged into the room from the top of the frame 5, thereby circulating and heating the indoor air. At the same time, the heating plate 2 radiates heat to the room through the mesh 11 on the protective panel 1.

[0041] Example 3

[0042] The present application embodiment provides a far-infrared electric fireplace based on embodiment 1. Figure 5 The far-infrared electric fireplace of this embodiment adds a second flame visual effect simulator, and the second flame visual effect simulator is arranged on two sides of the frame 5.

[0043] The second flame visual effect simulator has the same structure as the flame visual effect simulator, and the height of the display screen 7 of the second flame visual effect simulator is the same as the height of the display screen 7 of the flame visual effect simulator. This design enables the front and both sides of the electric fireplace to have a visual effect of simulated flames, making the flame effect three-dimensional, and further enhancing the illusion that the electric fireplace has a burning inner cavity.

[0044] Example 4

[0045] The present application embodiment provides a far-infrared electric fireplace based on embodiment 1. Figure 6 , which is different from Example 1, the structure of the flame visual effect simulator is different.

[0046] The flame visual effect simulator of the present embodiment is composed of a transparent plate 81, a plurality of lighting tubes 82 and a plurality of humidifiers 83. The transparent plate 81 is preferably a rectangular plate. The lighting tubes 82 can emit flame-colored light, such as orange-yellow light. The transparent plate 81 needs to be installed after a window 12 is opened on the protective panel 1. The transparent plate 81 can be attached and fixed to the inner surface or the outer surface of the protective panel 1, and only needs to cover the window 12. The lighting tubes 82 and the humidifiers 83 are both located in the far-infrared electric fireplace and below the transparent plate 81. The lighting tubes 82 and the humidifiers 83 cannot be observed from outside the far-infrared electric fireplace. The plurality of lighting tubes 82 are arranged in a row equidistantly along the length direction of the transparent plate 81, and the plurality of humidifiers 83 are also arranged in a row equidistantly along the length direction of the transparent plate 81. The lighting tubes 82 are located below the humidifiers 83 and correspond one to one. The mist of the humidifier 83 floats under the action of the rising air flow, and the lighting tube 82 shines flame-colored light on the mist, thereby creating a flame effect. The humidifier 83 can also humidify the indoor air at the same time.

[0047] Example 5

[0048] The embodiment of the present application provides a far-infrared electric fireplace based on the embodiment 4. The difference from the embodiment 4 is that the structure of the flame visual effect simulator is different.

[0049] The flame visual effect simulator of this embodiment is composed of a transparent plate 81, a resin block imitating the appearance of a carbon block, and a lamp. A window 12 facing the resin block is provided on the protective panel 1, and the transparent plate 8 is fixed on the protective panel 1 and covers the window 12. The resin block is formed by solidifying the resin by pouring the mold, and the mold is a mold of the carbon block. When pouring the resin, the lamp is placed in the mold in advance, so that the lamp is embedded in the resin block. By matching the light color of the lamp with the surface color of the resin block, a simulated scene of a burning carbon block can be displayed.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
