Description

Technical Field

[0001] This invention relates to the field of electric fireplaces, and more particularly to a 3D projection portable electric fireplace. Background Technology

[0002] Electric fireplaces are a common heating device. They achieve a simulated heating effect by combining a heating system and a simulated 3D projected flame system inside the fireplace, thus replacing traditional fireplaces.

[0003] Electric fireplaces can be broadly classified into built-in, wall-mounted, and portable types. Portable electric fireplaces, due to their ease of movement, can be flexibly placed without spatial limitations, making them convenient to move to different rooms or offices.

[0004] Electric fireplaces typically generate heat through internal heating elements, which are then dissipated into the room via a fan. However, existing electric fireplaces have limited heating range and cannot adequately meet the demand. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing an electric fireplace with a wider heating range. To solve the aforementioned technical problems, this invention offers the following technical solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A 3D projection portable electric fireplace includes a housing with a ventilation chamber inside. The housing also has a front air outlet grille connected to the ventilation chamber, side air outlet grilles on both sides, and a rear air inlet grille. A heating device is placed inside the ventilation chamber and has an air inlet and an air outlet, the air outlet being connected to the front air outlet grille. A flow guide is disposed inside the housing and forms a flow channel with the inner wall of the housing. The flow guide channel connects the air outlet and the side air outlet grilles. Hot air flows out from the two side air outlet grilles through the flow guide channel and enters the room, expanding the heating range.

[0007] Preferably, the air guide includes: a first plate segment having an air guide port communicating with the air outlet; and a second plate segment extending from one end of the first plate segment toward the side air outlet grille, the air guide directing warm air to the side air outlet grille.

[0008] Preferably, it also includes several diversion pipes, which are located below the side air outlet grille and one end is connected to the guide channel. Several air outlet holes are also provided on the diversion pipes. The diversion pipes and air outlet holes further expand the heating range.

[0009] Preferably, it further includes an opening and closing assembly, which includes: a lock body connected to the air guide, the lock body having an opening communicating with the air guide channel; and a bolt connected to the lock body and rotatable relative to the lock body; wherein, when the opening and closing assembly is in the closed state, the bolt closes the opening to block the communication between the air guide and the side air outlet grille, and the opening and closing assembly controls whether hot air enters the air guide channel, thereby controlling whether hot air blows from the side air outlet grille.

[0010] Preferably, the device further includes at least one suspension assembly disposed on the upper side of the housing. The suspension assembly includes: a frame slidably connected to the housing; a first support member connected to the frame and having an unfolded position extending from the frame and a folded position housed within the frame; and a drive assembly connected to the first support member and capable of driving the first support member to switch between the unfolded position and the folded position. When the first support member is in the folded position, the frame is located within the housing; when the first support member is in the unfolded position, the frame slides out of the housing. The suspension assembly is used to hang clothing, and hot air blown from the side air grille and air outlet dries the clothing.

[0011] Preferably, the driving assembly includes: a guide seat, which is horizontally slidable relative to the frame, and has a first guide groove and a second guide groove; a driving rod, which is connected to the guide seat and vertically slidable relative to the frame, and has a first guide block slidably connected to the first guide groove; and a driving block, which is connected to the housing and slidably connected to the second guide groove; wherein, a first support member is connected to the driving rod and one end of the first support member is rotatably connected to the frame; when the frame slides relative to the housing, the driving block can force the guide seat to slide horizontally to drive the driving rod to slide vertically, and the first support member deflects around the rotation axis of the frame to extend one end out of the frame; the driving assembly is used to drive the first support member to unfold, thereby expanding the space and facilitating the increase of the distance for hanging clothes on both sides.

[0012] Preferably, it also includes an extension component, which includes: a frame that is slidably connected to the frame body; and several second support members that are connected to both sides of the frame to increase the number of clothes that can be hung.

[0013] Preferably, it further includes a limiting component, which includes: a locking member disposed inside the housing; and a locking groove formed on the side of the frame; wherein, when the first support member is in the unfolded position and the folded position, the locking member is connected to the locking groove, and the limiting component is used to fix the frame, thereby maintaining the stability of the frame before and after movement.

[0014] Preferably, it also includes a linkage component, which includes: a drive gear connected to a locking bolt; and a rack located on the side of the frame; wherein, when the first support member switches from the folded position to the unfolded position, the drive gear and the rack mesh with each other to drive the locking bolt to rotate, causing the air guide to connect with the side air outlet grille, and the linkage component causes the side air outlet grille to automatically open and blow out warm air when the frame moves outward.

[0015] Preferably, the limiting component is located on the upper side of the linkage component, and the opening and closing component further includes a lever on the housing. The lever can mesh with the drive gear and can adjust the air volume of the side air outlet grille and the air outlet hole, or can control the use of the air outlet grille and the air outlet hole independently.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention increases the heating range by setting up an air outlet channel and a side air outlet grille, allowing warm air to be blown out from the side air outlet grille through the air outlet channel; it further increases the heating range by setting up a diversion pipe connected to the guide channel; and it combines an opening and closing component to control the opening and closing of the guide channel and adjust the opening degree.

[0017] By setting up a suspension assembly, after it moves outward from the housing, clothes can be hung on the first and second supports. Hot air blown from the side air grilles and air vents blows onto the clothes, thereby drying them. The first support expands to both sides under the action of the drive assembly, which increases the distance between the clothes hanging on both sides, which is beneficial for drying clothes. The second support can slide along the frame's moving direction, and can slide out between the first supports on both sides, increasing the distance between the clothes hanging on the first and second supports, which is beneficial for ventilation and drying.

[0018] As the frame moves outward, its rack and pinion mechanism activates the opening and closing components. Without manual intervention, this allows the closed airflow channel to open, enabling hot air to escape from the side air grilles and vents, drying the suspended clothes. A toggle switch adjusts the airflow through the side air grilles and vents. Furthermore, the linkage mechanism allows the side airflow function to open simultaneously with the unfolding of the hanging assembly, achieving a near-automatic drying function.

[0040] Please see Figures 1-15A 3D projection portable electric fireplace includes a housing 1 and a heating device installed inside the housing 1. The housing 1 has a ventilation chamber 11, and also has a front air outlet grille 12 connected to the ventilation chamber 11, side air outlet grilles 13 on both sides, and a rear air inlet grille 14. Air enters through the rear air inlet grille 14, forming warm air, and then flows out through the front air outlet grille 12 and side air outlet grilles 13.

[0041] The heating device is placed in the air cavity 11 to heat the air entering the air cavity 11. It has an air inlet 16 and an air outlet 15. The air outlet 15 is connected to the front air outlet grille 12. Hot air enters from the air inlet 16 and then flows out from the air outlet 15 and the front air outlet grille 12 into the room.

[0042] This electric fireplace is also equipped with a flow guide 2. The flow guide 2 is located inside the housing 1 and has a gap between it and the inner wall of the housing 1 to form a flow guide channel 21. The flow guide channel 21 connects the air outlet 15 and the side air outlet grille 13. Some hot air enters the flow guide channel 21 from the air outlet 15. The hot air flows out from the two side air outlet grilles 13 through the flow guide channel 21 and enters the room, thereby expanding the heating range.

[0043] The guide member 2 is generally L-shaped and includes a first plate segment 22 and a second plate segment 23 connected to each other. The first plate segment 22 has a guide port 24 that communicates with the air outlet 15. The guide port 24 has a guide plate 221. One end of the guide plate 221 is bent toward the air outlet 15. A portion of the air blown toward the air outlet 15 is guided along the inner wall of the guide plate 221 and then enters the guide channel 21 from the guide port 24.

[0044] The second plate segment 23 extends from one end of the first plate segment 22 toward the side air outlet grille 13. In this embodiment, the second plate segment 23 is arranged parallel to the inner sidewall of the housing. Hot air first passes through the guide channel 21 of the first plate segment 22, then flows into the guide channel 21 of the second plate segment 23, and then flows out from the side air outlet grille 13.

[0045] The flow guide 2 also includes several diversion pipes 25. The diversion pipes 25 are connected to the housing 1. The diversion pipes 25 are located below the side air outlet grille 13 and one end is connected to the flow guide channel 21. The upper end of the diversion pipes 25 is connected to the flow guide channel 21. Several air outlet holes 251 are also provided on the diversion pipes 25. The air outlet holes 251 are distributed along the length of the diversion pipes 25. The multiple air outlet holes 251 further expand the heating range.

[0046] This electric fireplace also includes an opening and closing assembly 26, which includes a lock body 261 connected to the air guide 2 and placed in the air guide channel 21. The lock body 261 has a contact surface on both sides, and the two contact surfaces contact the air guide plate 221 on the corresponding side and the inner wall of the housing 1 respectively. The lock body 261 has an opening 2611 that connects to the air guide channel 21. Hot air enters from the air guide port 24 and flows into the air guide channel 21 of the second plate section 23 through the opening 2611.

[0047] The opening and closing assembly 26 also includes a bolt 262, which is connected to the lock body 261 and can rotate relative to the lock body 261. The bolt 262 includes a plate 2621 and a rotating rod 2622 connected to the plate 2621. The plate 2621 contacts the inner wall of the lock body 261 and has a certain width to close the opening 2611.

[0048] The rotating rod 2622 is rotatably engaged with the lock body 261. The thickness of the plate body 2621 is less than the width of the opening 2611. When the opening and closing assembly 26 is in the closed state, the locking bolt 262 closes the opening 2611 to block the connection between the guide port 24 and the side air outlet grille 13. By rotating the rotating rod 2622, the plate body 2621 can be controlled, thereby controlling whether hot air enters the guide port 24, and the flow rate of hot air can also be adjusted.

[0049] This electric fireplace also includes at least one suspension assembly 3 disposed on the upper side of the housing 1. The suspension assembly 3 includes a frame 31. The upper side of the housing 1 is provided with a main body portion 17 and a cover plate 18 connected to each other. The frame 31 is slidably connected to the main body portion 17. In this embodiment, the main body portion 17 has a function to accommodate two sets of symmetrically arranged suspension assemblies 3. A pull rod is connected to the outer side of the frame 31 to facilitate the movement of the frame 31. The frame 31 is located above the side air outlet grille 13. The frame 31 can slide out of the housing 1 from the main body portion 17, and the sliding direction of the frame 31 is the same as the air outlet direction of the side air outlet grille 13.

[0050] The suspension assembly 3 also includes a first support member 32 and a drive assembly 33, which are connected to the frame 31 and have an unfolded position extending out of the frame 31 and a folded position housed in the frame 31. The first support member 32 is symmetrically arranged about the frame 31. When the first support member 32 is in the unfolded position, it can hang clothes. Hot air blown out from the side air grille 13 dries the clothes. The first support member 32 has a hanging groove to prevent the hung clothes from falling off.

[0051] The drive assembly 33 is connected to the first support member 32 and can drive the first support member 32 to switch between an unfolded position and a folded position. During the outward sliding of the frame 31, the drive assembly 33 causes the first support member 32 to unfold. When the first support member 32 is in the folded position, the frame 31 is placed inside the housing 1. When the first support member 32 is in the unfolded position, the frame 31 slides out of the housing 1. The first support member 32 is set close to the side of the frame 31. The drive assembly 33 causes the first support members 32 on both sides of the frame 31 to unfold in opposite directions to expand the space and increase the distance for hanging clothes on both sides.

[0052] The drive assembly 33 includes a guide seat 331, a drive rod 332, and a drive block 334. The guide seat 331 can slide horizontally relative to the frame 31. The guide seat 331 is slidably connected to the inner side plate of the frame 31. A slider is connected to the guide seat 331. A sliding groove is formed on the inner side plate of the frame 31. The guide seat 331 has a first guide groove 3311 and a second guide groove 3312. The first guide groove 3311 is used for the unfolding and folding of the first support member 32, and the second guide groove 3312 is used for the horizontal movement of the frame 31. The drive rod 332 is connected to the guide seat 331 and can slide vertically relative to the frame 31. The drive rod 332 is slidably connected to the frame 31 and has a first guide block 333 that is slidably connected to the first guide groove 3311. The first guide block 333 is inserted into the first guide groove 3311. When the guide seat 331 moves horizontally, the drive rod 332 moves vertically. The drive block 334 is connected to the cover plate 18 and can be slidably connected to the second guide groove 3312. The second guide groove 3312 has an inlet end. When the frame 31 moves outward, the drive block 334 enters the second guide groove 3312, causing the guide seat 331 to move horizontally. The first support member 32 is connected to the drive rod 332, and one end of the first support member 32 is rotatably connected to the frame 31. When the frame 31 slides relative to the housing 1, the drive block 334 can force the guide seat 331 to slide horizontally, thereby driving the drive rod 332 to move. Sliding vertically, the first support member 32 deflects around the rotation axis 335 of the frame 31 and extends out of the frame 31 at one end. Specifically, an extension plate 336 is fixedly connected to the rotation axis 335, and a rotation groove 3361 is opened on the extension plate 336. A rod body 337 is rotatably connected to the drive rod 332 and is inserted into the rotation groove 3361. When the drive rod 332 moves, the rod body 337 moves, thereby causing the extension plate 336 and the first support member to rotate around the rotation axis 335, and the first support member 32 rotates out of the frame 31.

[0053] The electric fireplace also includes an extension component 34, a limiting component 35, and a linkage component 36. The extension component 34 includes a frame 341 and a second support member 342. A support plate is provided on the frame 31, and the support plate is located in the middle of the frame 31. The frame 341 is slidably connected to the support plate, and a stop is provided on the support plate to prevent the frame 341 from falling off. A pull rod is connected to the frame 341 to facilitate the movement of the extension component 34. The second support member 342 is connected to both sides of the frame 341. The second support member 342 is also provided with a hanging groove. Multiple second support members 342 are connected to both sides of the frame 341 to hang objects. The sliding direction of the second support member 342 is the same as the sliding direction of the frame 31. This setting can adjust the distance between the second support member 342 and the side air vent grille 13, thereby controlling the distance between the clothes hanging on the second support member 342 and the side air vent grille 13. At the same time, it can also increase the distance between the clothes on it and the clothes hanging on the first support member 32.

[0054] The limiting component 35 includes a locking piece 351 disposed within the main body 17. A slot 352 is provided on the side of the frame 31. When the first support member 32 is in the unfolded position and the folded position, the locking piece 351 is connected to the slot 352. In this application, the locking piece 351 is an elastic locking plate. Two locking pieces 351 are corresponding to one side of the frame 31, which respectively fix the frame 31 before and after movement. During the outward movement of the frame 31, when the locking piece 351 is locked in the slot 352, the frame 31 stops moving. The fixing of the frame 31 keeps the drive component 33 stable, thereby keeping the first support member 32 in a stable unfolded state.

[0055] The linkage assembly 36 includes a drive gear 361 and a rack 362, which are connected to the locking bolt 262. Specifically, the rod 337 extends upward, and the drive gear 361 is connected to the upper end of the rod 337. The rack 362 is located on the side of the frame 31. Specifically, the rack 362 is located above the clip 351 and is fixed to the side of the frame 31. When the first support 32 is switched from the folded position to the unfolded position, the drive gear 361 and the rack 362 mesh with each other to drive the locking bolt 262 to rotate, causing the guide port 24 to connect with the side air outlet grille 13. During the outward sliding of the frame 31, the rack 362 meshes with the drive gear 361, causing the drive gear 361 to rotate, thereby causing the rod 337 to rotate. The rod 337 rotates the plate 2621, thereby opening the closed opening 2611 unblocking, allowing warm air to enter the guide channel 21 and be blown out from the side air outlet grille 13 and the air outlet 251 to dry the clothes. During the process of pulling out the frame 31, the rack 362 first meshes with the drive gear 361, and after the rack 362 separates from the drive gear 361, the clip 351 then snaps into the slot 352.

[0056] The limiting component 35 is positioned on the side of the linkage component 36 away from the side air outlet grille 13, ensuring that the airflow channel 21 can only be opened after the frame 31 is locked.

[0057] The opening and closing assembly 26 also includes a lever 263 disposed on the housing 1. The lever 263 is slidably connected to the housing 1 and can mesh with the drive gear 361. The arrangement of the lever 263 enables the suspension assembly 3 to control the side airflow even when it is in the housing state.

[0058] Specifically, the lever 263 and the rack 362 are located on both sides of the drive gear 361. The side of the lever 263 facing the drive gear 361 is connected with multiple teeth. The lever 263 can move to make the drive gear 361 rotate, and then control whether hot air enters the guide port 24 through the locking bolt 262. The size of the opening 2611 can be controlled by moving the lever 263 by different distances, thereby controlling the strength of the hot air blown out by the side air grille 13 and the air outlet 251, so that the amount of hot air blown towards the hanging clothes is controllable.
