Description

Technical Field

[0001] The invention relates to the field of electric fireplaces, and in particular to an electric fireplace heater with multiple flame simulation effects. Background Art

[0002] A fireplace is an indoor heating device that is independent or built on a wall. It uses combustibles as energy and has a chimney inside. It originated from the heating facilities of Western families or palaces. Since its fuel is a renewable resource, it is still widely used in the West after being modernized and improved, especially among the higher education class who advocate environmental protection. Many people in Chinese cities live in high-rise buildings. It is difficult to install a chimney if a traditional fireplace is used. In order to have a warmer atmosphere in winter, electric fireplaces came into being.

[0003] At present, most of the flame simulation devices of electric fireplaces on the market use a light source to illuminate the moving parts, and then the reflective elements on the moving parts reflect and project the images, such as a simulated flame simulation device mentioned in CN200920118478.9. This flame simulation device usually requires an imaging screen, and the flame projection is flat and lacks three-dimensional effect. There are also ways to increase the three-dimensional effect of the flame simulation device by adding a simulated fuel bed with lights, but the simulated fuel bed usually only emits light by itself, and cannot form the shape of a floating flame, which is not realistic enough.

[0004] At present, there are also some atomized electric fireplaces that use fog or water vapor combined with light to achieve three-dimensional flame simulation. The flame effect brought by the fog is realistic, but usually the flame simulation device has an independent flame effect adjustment control device. It often happens that when the electric fireplace heater discharges a large amount of warm air, the flame simulation is in a low fire state, or when the electric fireplace heater is working at low power, the flame simulation device displays a high fire state, and the user needs to manually adjust it to keep the working state of the electric fireplace heater corresponding to the flame simulation effect.

[0018] 3. Beneficial Effects

[0019] Compared with the prior art, the present invention generates mist by installing a mist generating unit in a lower mounting cavity at the bottom of the electric fireplace body. The mist enters the simulated solid fuel installed at the first opening through the first opening of the lower partition plate, and enters the flame generating area through the second opening and the mist outlet. The light source in the shell is started to illuminate the mist at the mist outlet to simulate the effect of flame. When the user starts the electric fireplace heater for heating, the hot air generating unit in the upper mounting cavity on the upper side of the upper partition plate is started to generate hot air. Air enters the upper mounting cavity from the air inlet and is discharged from the air outlet after being heated by the hot air generating unit. The hot air generating unit accelerates the air flow speed in the upper mounting cavity, thereby generating negative pressure to drive the gas in the flame generating area to flow into the upper mounting cavity, thereby driving the mist at the mist outlet of the simulated solid fuel to move toward the air inlet. The greater the power of the hot air generating unit, the greater the attraction to the mist, thereby making the mist flow more intense, and the flame simulation effect of the simulated solid fuel more intense, so that the flame simulation effect of the simulated solid fuel can be automatically changed according to the heating effect of the electric fireplace heater.

[0020] The presence of the arc-shaped guide plate in the flame generation area can make the mist move toward the upper air inlet in a direction and gather at the top of the arc-shaped guide plate to form a smoke effect when the flame is burning. The hot air generated by the hot air generating unit can discharge the mist in time, which is beneficial to humidify the external environment and prevent the mist from affecting the electronic components of the hot air generating unit.

[0021] The upwardly moving mist is also illuminated by spotlights at both ends of the shell to simulate the effect of flames. The LED light strips arranged around the working ends of the spotlights can adjust the color of the flame to a certain extent to meet the preferences of different users.

[0022] Furthermore, a multifaceted pyramid is installed on the mounting seat in the middle of the second opening. The multifaceted pyramid has multiple inclined surfaces to reflect the light from the spotlights at both ends, thereby increasing the lighting effect on the mist at the mist outlet. Moreover, as the multifaceted pyramid rotates, the irradiation angle of the light can be changed, and the dynamic effect of the flame can be achieved in combination with the irregular movement of the mist itself, thereby improving the visual effect of the electric fireplace.

[0042] Embodiment 1:

[0043] like Figures 1 to 13 As shown, the present embodiment provides an electric fireplace heater with multiple flame simulation effects, including an electric fireplace body 1 and a plurality of simulated solid fuels 2; an upper partition 1a and a lower partition 1b are arranged in the electric fireplace body 1, the upper partition 1a and the lower partition 1b are arranged horizontally, an upper mounting cavity 1c is formed between the upper partition 1a and the top of the electric fireplace body 1, a flame generating area 1d is formed between the upper partition 1a and the lower partition 1b, a lower mounting cavity 1e is formed between the lower partition 1b and the bottom of the electric fireplace body 1, and a panel 1f is fixedly installed on the front side of the electric fireplace body 1; a mist generating unit 3 is arranged in the lower mounting cavity 1e, and a plurality of first openings 1b1 are arranged on the lower partition 1b on the upper side of the lower mounting cavity 1e, the first openings 1b1 connect the flame generating area 1d and the lower mounting cavity 1e, and the simulated solid fuel 2 is fixedly installed at the first openings 1b1; the simulated solid fuel 2 includes a shell 2a, the outer wall of the shell 2a is provided with simulated patterns, and the shell 2a A mist outlet 2a1 extending in the length direction is arranged at the top of the simulated solid fuel 2, mounting feet 2a2 are arranged at both ends of the bottom of the simulated solid fuel 2, the simulated solid fuel 2 is inserted at the first opening 1b1 through the mounting feet 2a2, a second opening 2a3 is arranged between the mounting feet 2a2, and the mist generated by the hot air generating unit 4 enters the flame generating area 1d through the first opening 1b1, the second opening 2a3 and the mist outlet 2a1; light sources 2b are arranged at both ends of the shell 2a of the simulated solid fuel 2, and the light source 2b irradiates the mist to form a simulated flame; An arc-shaped guide plate 1d1 is arranged in the flame generating area 1d, and an air inlet 1a1 is arranged on the top of the flame generating area 1d, and the air inlet 1a1 is connected to the upper mounting cavity 1c; an air inlet 1c1 is arranged on the top of the rear side of the electric fireplace body 1, and the air inlet 1c1 is connected to the upper mounting cavity 1c; an air outlet 1f1 is arranged on the panel 1f, and the air outlet 1f1 is connected to the upper mounting cavity 1c; a hot air generating unit 4 is arranged in the upper mounting cavity 1c, and the input end of the hot air generating unit 4 is connected to the air inlet 1c1, and the output end of the hot air generating unit 4 is connected to the air outlet 1f1.

[0044] Specifically, the electric fireplace body 1 of the present embodiment divides the internal space into an upper installation chamber 1c, a flame generating area 1d and a lower installation chamber 1e which are distributed from top to bottom through an upper partition 1a and a lower partition 1b. The mist generating unit 3 is installed in the lower installation chamber 1e at the bottom of the electric fireplace body 1 to generate mist. The mist enters the simulated solid fuel 2 installed at the first opening 1b1 through the first opening 1b1 of the lower partition 1b. The shell 2a of the simulated solid fuel 2 can be made into various simulated fuel shapes, such as charcoal, firewood, coal, etc. The shell 2a is installed by the foot 2a2 Inserted at the first opening 1b1, the bottom of the mounting foot 2a2 can be provided with an inclined surface so that according to the Coanda effect, the mounting foot 2a2 enters the shell 2a along the inclined surface of the mounting foot 2a2, and enters the flame generating area 1d through the second opening 2a3 and the mist outlet 2a1. At this time, the light source 2b in the shell 2a is started to illuminate the mist at the mist outlet 2a1 to simulate the effect of flame. From the outside, the multiple simulated solid fuels 2 in the flame generating area 1d can produce a 3D flame effect, and the overall visual feeling is good. In this embodiment, an air inlet 1a1 is provided on the upper partition 1a at the top of the flame generating area 1d. When the user starts the electric fireplace heater for heating, the hot air generating unit 4 in the upper mounting cavity 1c on the upper side of the upper partition 1a is started to generate hot air, and the air enters the upper mounting cavity 1c from the air inlet 1c1, and is heated by the hot air generating unit 4 and is discharged from the air outlet 1f1 The hot air generating unit 4 accelerates the air flow speed in the upper installation cavity 1c, thereby generating negative pressure to drive the gas in the flame generation area 1d to flow into the upper installation cavity 1c, thereby driving the mist at the mist outlet 2a1 of the simulated solid fuel 2 to move toward the air inlet 1a1. The greater the power of the hot air generating unit 4, the greater the attraction to the mist, thereby making the mist flow more violently, and the flame simulation effect of the simulated solid fuel 2 is also more violent, so that the flame simulation effect of the simulated solid fuel 2 can be automatically changed according to the heating effect of the electric fireplace heater. The presence of the arc-shaped guide plate 1d1 in the flame generation area 1d can make the mist move directionally toward the upper air inlet 1a1 and converge at the top of the arc-shaped guide plate 1d1 to form a smoke effect when the flame is burning. The hot air generated by the hot air generating unit 4 discharges the mist in time, which is beneficial to humidifying the external environment and preventing the mist from affecting the electronic components of the hot air generating unit 4.

[0045] like Figures 11 to 13As shown, the light source 2b includes a power supply 2b1, a spotlight 2b2 and an LED light strip 2b3. The power supply 2b1 is fixedly installed at the two ends of the shell 2a. The spotlights 2b2 at the two ends of the shell 2a are arranged opposite to each other. The LED light strip 2b3 is evenly distributed around the outside of the spotlight 2b2. The spotlight 2b2 and the LED light strip 2b3 are electrically connected to the power supply 2b1. A mounting seat 2c is provided in the middle of the second opening 2a3 of the shell 2a. A polyhedral pyramid 2c1 is rotatably installed on the mounting seat 2c. The rotation axis of the polyhedral pyramid 2c1 is vertically arranged. The polyhedral pyramid 2c1 has a cross-section that gradually decreases from bottom to top. The polyhedral pyramid 2c1 reflects the light from the light source 2b.

[0046] The light sources 2b of this embodiment are installed at both ends of the shell 2a, and the power supply 2b1 supplies power to the spotlights 2b2 and the LED light strip 2b3. When the light source 2b is started, the spotlights 2b2 at both ends illuminate the upwardly moving mist to simulate the effect of flame. The LED light strip 2b3 arranged around the working end of the spotlight 2b2 can adjust the color of the flame to a certain extent to meet the preferences of different users. A multifaceted pyramid 2c1 is installed on the mounting seat 2c in the middle of the second opening 2a3. The multifaceted pyramid 2c1 has multiple inclined surfaces to reflect the light of the spotlights 2b2 at both ends, thereby increasing the lighting effect of the mist at the mist outlet 2a1, and with the rotation of the multifaceted pyramid 2c1, the irradiation angle of the light can be changed, and the irregular movement of the mist itself can be coordinated to achieve the dynamic effect of the flame, and the mist at the mist outlet 2a1 is illuminated to simulate the dynamic effect of the flame, thereby improving the visual effect of the electric fireplace.

[0047] Further, such as Fig. 9 and Fig.10 As shown:

[0048] A first light-transmitting strip 2a4 is arranged around the mist outlet 2a1 of the housing 2a; a plurality of second light-transmitting strips 2a5 are arranged around the housing 2a; the first light-transmitting strip 2a4 and the second light-transmitting strip 2a5 are made of light-transmitting transparent material.

[0049] Based on the above embodiments, the technical problem that this embodiment wants to solve is how to ensure that the flame simulation effect is realistic. To this end, this embodiment sets a first light-transmitting strip 2a4 at the mist outlet 2a1 and sets a plurality of second light-transmitting strips 2a5 around the shell 2a. When the light source 2b is started, the light illuminates the first light-transmitting strip 2a4 to hide the mist outlet 2a1. The existence of the second light-transmitting strip 2a5 can make the simulated solid fuel 2 produce a real burning state. The light is reflected by the multi-faceted pyramid 2c1 and hits the second light-transmitting strip 2a5 to form a flickering spark effect, which is combined with the texture on the outside of the shell 2a to improve the flame simulation effect of the simulated solid fuel 2.

[0050] Further, such as Figures 3 to 6As shown:

[0051] The cross-sectional shape of the flame generating area 1d is an isosceles trapezoid, and the two sides of the flame generating area 1d are gradually inclined from the inside to the outside, and lenses 1d2 are fixedly installed on both sides of the flame generating area 1d; grooves 1d3 are provided on both sides of the flame generating area 1d, and the grooves 1d3 are located on the rear side of the lens 1d2, and heating wires 1d4 are provided in the grooves 1d3; the heating wires 1d4 are attached to the rear side of the lens 1d2 to heat the lens 1d2.

[0052] Based on the above embodiments, the technical problem that this embodiment intends to solve is how to improve the display effect of the flame simulation effect of the simulated solid fuel 2 in the flame generation area 1d. To this end, this embodiment forms an isosceles trapezoidal shape by tilting the two sides of the flame generation area 1d from the inside to the outside. The arc-shaped guide plates 1d1 installed on both sides of the flame generation area 1d can mirror the flame effect generated by the simulated solid fuel 2 in the flame generation area 1d, so that the visual space in the flame generation area 1d is larger, and the user can view the flame simulation effect of the simulated solid fuel 2 through the arc-shaped guide plates 1d1 at multiple angles. The lens 1d2 set on the rear side of the arc-shaped guide plate 1d1 is used to install the groove 1d3. The groove 1d3 is rotated to fit the rear side of the arc-shaped guide plate 1d1. The groove 1d3 starts to heat the arc-shaped guide plate 1d1 after the device is turned off, thereby preventing the mist from condensing on the arc-shaped guide plate 1d1 and affecting the reflection effect of the arc-shaped guide plate 1d1.

[0053] like Figure 5 As shown, the panel 1f includes a transparent area 1f2 and a metal area 1f3, wherein the transparent area 1f2 is located in front of the flame generating area 1d, and the metal area 1f3 is located in front of the upper mounting cavity 1c and the lower mounting cavity 1e. The panel 1f of this embodiment shields the hot air generating unit 4 installed in the upper mounting cavity 1c on the upper side of the electric fireplace body 1 and the mist generating unit 3 in the lower mounting cavity 1e below through the metal area 1f3, and the transparent area 1f2 is arranged at the flame generating area 1d to facilitate display of the flame simulation effect of the simulated solid fuel 2 in the flame generating area 1d. When repairing the device, the user only needs to disassemble the panel 1f.

[0054] like Figure 4 and Figure 5 As shown, the mist generating unit 3 includes a water tank 3a and an atomizer 3b, the water tank 3a is installed in the lower installation cavity 1e, and the atomizer generator 3b is arranged inside the water tank 3a; a through hole 1f4 is arranged at the bottom of the panel 1f, and a water inlet pipe 3a1 is arranged on the upper side of the water tank 3a to connect with the inside of the water tank 3a, and the water inlet pipe 3a1 extends through the through hole 1f4 to the outside of the lower installation cavity 1e; a plurality of spray nozzles 3a2 are also arranged on the upper side of the water tank 3a, and the working end of the spray nozzle 3a2 is arranged to align with the first opening 1b1 of the upper lower partition 1b.

[0055] Based on the above embodiments, the technical problem to be solved in this embodiment is how to display mist in the mist generating unit 3. To this end, in this embodiment, a certain amount of liquid is stored in the water tank 3a, and the atomizing generator 3b atomizes the liquid in the water tank 3a and sprays it upward through the spray nozzle 3a2 on the top of the water tank 3a. The atomizing generator 3b is a prior art and is relatively mature, so it will not be described in detail here. The water tank 3a is inserted into the through hole 1f4 of the panel 1f through the water inlet pipe 3a1, so that the user can directly add liquid into the water tank 3a.

[0056] like Figure 4 As shown, the hot air generating unit 4 includes an air duct 4a, a heating unit 4b and a cross-flow fan 4c; the air duct 4a is horizontally arranged, and the air inlet end of the air duct 4a is connected to the air inlet 1c1 of the electric fireplace body 1; the heating unit 4b is fixedly installed at the air outlet end of the air duct 4a, and the heating unit 4b is arranged on one side of the cross-flow fan 4c; the cross-flow fan 4c is fixedly installed on one side of the upper mounting cavity 1c close to the air outlet 1f1.

[0057] Based on the above embodiments, the technical problem to be solved in this embodiment is how the hot air generating unit 4 can achieve the segment effect. To this end, the hot air generating unit 4 in this embodiment drives the air flow through the cross flow fan 4c, and the cross flow fan 4c sucks the external air into the air duct 4a through the air inlet 1c1 through the air duct 4a. The air is heated when passing through the heating unit 4b and discharged through the air outlet 1f1 to achieve the heating function. The heating unit 4b can be a heating rod or a heater, which are both existing technologies and are relatively mature, and will not be described in detail here.

[0058] Embodiment 2:

[0059] Compared with Example 1, in this embodiment, Figure 8 and Fig.13As shown, a shaft rod 2c2 is coaxially arranged at the bottom of the multifaceted pyramid 2c1, the shaft rod 2c2 is inserted into the mounting seat 2c, and the shaft rod 2c2 extends vertically downward to the bottom of the lower partition 1b; a rotating gear 2c3 is coaxially arranged at the bottom of the shaft rod 2c2; a first rotating drive device 2d is fixedly installed below the lower partition 1b, and the working end of the first rotating drive device 2d is connected to the transmission belt 2d1, and the transmission belt 2d1 is connected to the rotating gear 2c3 of each simulated solid fuel 2. The polyhedral pyramid 2c1 of the present embodiment is inserted on the mounting base 2c through the shaft 2c2, and the rotating gear 2c3 arranged at the bottom of each shaft 2c2 is connected through the transmission belt 2d1. When the first rotation drive device 2d is started to drive the driving gear connected to the transmission belt 2d1 on the working end of the first rotation drive device 2d to rotate, the transmission belt 2d1 drives the rotating gears 2c3 on all the simulated solid fuels 2 to rotate, thereby driving the polyhedral pyramid 2c1 to rotate to ensure the dynamic flame effect of each simulated solid fuel 2. The first rotation drive device 2d can be a servo motor, and the manufacturer can also set the rotating gear 2c3 of each simulated solid fuel 2 to a different size to ensure that when the first rotation drive device 2d is started, the rotation rate of the polyhedral pyramid 2c1 of each simulated solid fuel 2 is different, thereby forming different dynamic effect change cycles, thereby improving the naturalness of the flame simulation effect.

[0060] like Figure 8 and Fig.13 As shown, four tensioning wheels 2c4 are inserted under the mounting seat 2c, and the tensioning wheels 2c4 are located on the peripheral side of the rotating gear 2c3. The rotating axis of the tensioning wheel 2c4 is parallel to the rotating axis of the rotating gear 2c3, and the transmission belt 2d1 fits the tensioning wheel 2c4 and the rotating gear 2c3; a limiting plate 2c5 is provided at the bottom of the tensioning wheel 2c4, and the diameter of the limiting plate 2c5 is larger than the diameter of the tensioning wheel 2c4, and the upper side of the limiting plate 2c5 fits the bottom of the transmission belt 2d1.

[0061] Based on the above embodiments, the technical problem that this embodiment intends to solve is how to ensure the stable transmission connection of a transmission belt 2d1 to each rotating gear 2c3. To this end, this embodiment inserts four tensioning wheels 2c4 under the mounting seat 2c of each simulated solid fuel 2. The tensioning wheels 2c4 are distributed on the circumference of the rotating gear 2c3. When the transmission belt 2d1 is connected to each rotating gear 2c3, it needs to pass between the tensioning wheels 2c4 and the rotating gear 2c3. The tensioning wheels 2c4 increase the contact area between the transmission belt 2d1 and the rotating gear 2c3, thereby increasing the wrap angle of the transmission belt 2d1 to the rotating gear 2c3, and ensuring the transmission effect of the transmission belt 2d1 to the rotating gear 2c3.

[0062] Furthermore, a plurality of guide blades 2c6 are provided at the bottom of the multifaceted pyramid 2c1. The guide blades 2c6 surround the circumference of the shaft 2c2 at equal intervals. The guide blades 2c6 rotate with the multifaceted pyramid 2c1 to guide the mist to move upward.

[0063] Based on the above embodiments, the technical problem to be solved in this embodiment is how to guide the mist generated by the hot air generating unit 4 into the housing 2a. To this end, in this embodiment, a plurality of guide vanes 2c6 are arranged on the shaft 2c2 at the bottom of the multi-faceted pyramid 2c1, and the first rotary drive device 2d drives the multi-faceted pyramid 2c1 to rotate, driving the guide vanes 2c6 to rotate, thereby guiding the mist in the lower mounting cavity 1e below into the housing 2a and into the flame generating area 1d through the mist outlet 2a1.

[0064] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
