Description

Technical Field

[0001] The present invention relates to the field of heaters, and specifically to a silent ceiling-mounted heater device. Background Art

[0002] CN202110399971.8 discloses a low-noise heater. The present invention includes a box body and a wind wheel. The box body includes a wind wheel cavity with an internal wind wheel and an air outlet channel extending outward from one side of the wind wheel cavity. Different-direction ventilation air outlets and warm air outlets are arranged on the air outlet channel. An active air damper is arranged between the ventilation air outlet and the warm air outlet. The air outlet channel selects one of the ventilation air outlet and the warm air outlet for air outlet by the action of the active air damper, optimizing the air outlet path and the exhaust path, making the use of the heater more convenient and intelligent. A noise reduction board is arranged in the box body, and the noise reduction board is located in the air outlet channel and / or the wind wheel cavity to reduce the noise during exhaust by reducing the air flow rate pouring back into the wind wheel and improving the user's use comfort.

[0003] Although the above device solves the noise generated by "the air flow impacting the side wall of the exhaust channel", similarly, the air flow will still impact the inner wall of the "volute", generating noise, and the closer to the "wind wheel", the easier it is to generate noise; moreover, since one "wind wheel" in the above device corresponds to one "warm air outlet", when the air volume increases, there may still be a problem that the air flow impacts the side wall of the "warm air outlet", generating noise; in addition, due to the setting of the "active air damper", heating and exhaust cannot be carried out simultaneously, resulting in the inability to timely discharge moisture and odors, or problems such as uneven heating, affecting the use experience. Therefore, the present invention provides a silent ceiling-mounted heater device. Summary of the Invention

[0004] The purpose of the present invention is to provide a silent ceiling-mounted heater device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

A hot air module is fixedly connected to one side inside the box body, and an air outlet is opened on the other side. An air outlet assembly is installed between the air outlet and the hot air module. A control center is fixedly connected to one side of the box body close to the air outlet; a pair of rotating structures are installed on the outer wall of the air outlet assembly for controlling the air volume delivered to the air outlet.

[0007] The air outlet assembly includes a pair of first motors, a pair of wind wheels and a pair of guide plates. The wind wheels are fixedly connected to the first motors and rotate with the first motors to generate air volume. The guide plates are located outside the wind wheels. The opposite ends of the pair of guide plates are fixedly connected to both sides of the hot air module, and the opposite ends are bent and fixedly connected to form a guiding channel for the flow of air volume. The air volume generated by the wind wheels flows through the guiding channel to the hot air module, and after being heated by the hot air module, it flows into the room;

[0009] Preferably, a straight flow guide plate and a folded flow guide plate are fixedly connected inside the guide plates for forcibly diverting the air volume so that it can flow evenly to the hot air module; the folded flow guide plate is bent towards the direction of the bent guide plate and can guide the air volume to flow to the middle of the hot air module, and the straight flow guide plate is away from the bent guide plate and can allow part of the air volume to flow to both sides of the hot air module.

[0010] Preferably, a sound absorption assembly is fixedly connected to the outer walls on the opposite sides of the guide plates.

The rotating assembly is fixedly connected to the end of the rotating guide plate, and the positioning assembly is fixedly connected to the outer wall of the rotating guide plate. The driving assembly moves to drive the rotating assembly, the rotating guide plate and the positioning assembly to rotate, and the lifting assembly is inserted into the positioning assembly in a matching manner to fix the rotating guide plate.

[0012] Preferably, the positioning assembly includes a positioning plate fixedly connected to the middle of the outer wall of the rotating guide plate and a positioning part with a hollow middle. The positioning part is fixedly connected to the end of the positioning plate close to the rotating guide plate, and the end of the positioning plate away from the rotating guide plate is bent.

[0013] Preferably, the rotating assembly includes a rotating shaft and fixing parts fixedly connected to the outer walls of the upper and lower parts of the rotating shaft. The rotating shaft is rotatably connected to the box body, and an annular groove is formed in the fixing part near the bottom of the box body; the fixing part is fixedly connected to the rotating guide plate.

[0014] Preferably, at the connection between the rotating guide plate and the fixed part, an arc-shaped notch is formed from the inner wall to the outer wall of the rotating guide plate, and a corresponding arc-shaped part matching the arc-shaped notch protrudes from the fixed guide plate. When the rotating guide plate rotates, the arc-shaped notch rotates along the inner and outer walls of the arc-shaped part, so that when the rotating guide plate rotates and after the rotation is completed, the inner wall still maintains a smooth transition with the inner wall of the fixed guide plate.

[0015] Preferably, the driving assembly includes a second motor, a driving plate and a pressing plate. A rack is provided on one side of the driving plate close to the rotating guide plate for meshing connection with the rotating shaft, and the other side is meshed with the second motor. The driving plate is slidably connected to the bottom of the box body; the length of the rack enables the rotating shaft to drive the rotating guide plate to rotate by 15 degrees or 30 degrees; the pressing plate is fixedly connected to the side of the driving plate close to the rotating guide plate and matches the annular groove, and one side of the pressing plate close to the bottom of the box body presses against the lifting assembly.

[0016] Preferably, the lifting assembly includes a telescopic block fixedly connected to the bottom of the box body, a telescopic plate slidably connected to the middle of the telescopic block, and a limit part in a shape similar to an L. The outer sides of the limit part are parallel to the pressing plate and the telescopic plate respectively, and are fixedly connected to the side of the telescopic plate. The end of the limit part parallel to the pressing plate protrudes to form a slope, and the other end of the pressing plate is hollowed out for matching the sloped end of the limit part.

[0017] Preferably, when the rotating guide plate fits with the fixed guide plate, or at the positions corresponding to the rotation of 15 degrees or 30 degrees, rubber is provided at the bottom of the box body and the inner wall of the box cover.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The present invention encloses a guiding channel through a pair of guide plates, a pair of first motors and a pair of wind wheels, which can make full use of the air volume generated by the wind wheels, reduce the loss of air volume, and use the straight guiding plate and the folded guiding plate to forcibly divide the air volume in the guiding channel, so that the air volume can flow evenly to the entire hot air module, avoiding the mutual impact of air volumes, or the noise caused by the air volume being too concentrated and only blowing to a specific position of the hot air module, as well as causing unnecessary loss of air volume, making the air volume flow more quietly, and at the same time facilitating the uniform heating of the air volume by the hot air module, optimizing the heating effect; the rotation structure provides the option of heating and exhausting at the same time, improving the use experience, and reducing the loss of air volume through the forced diversion of the straight guiding plate and the folded guiding plate, to a certain extent reducing the impact of exhaust on the heating effect;

[0020] The noise generated by blowing the air volume to the inner wall of the guide plate by the sound guide tube is transmitted to the sound-absorbing cotton and absorbed by the sound-absorbing cotton. The stabilizing plate and the fixing plate are arranged on the outside of the guide plate closest to the wind wheel, which can fully absorb the noise, making the air volume quieter when it is generated to the greatest extent. The stabilizing plate and the fixing plate can also reinforce the guide plate, so that the present invention operates quietly and stably during heating;

[0021] Driving the rotating guide plate to rotate through the rotating shaft can exhaust air while heating the room, making the heating more uniform and timely removing moisture and odors. The movement of the driving plate can drive the rotating guide plate to rotate successively and control the telescopic plate to insert into the positioning part, so as to achieve the effect of fixing the rotating plate after rotation and making the rotating guide plate more stable during air exhaust. At the same time, in the rotating structure, except for the second motor, mechanical structure design is adopted, which also makes the overall structure stable, more environmentally friendly, has a long service life and lower cost.

[0022] Notches are opened on the inner wall of the rotating guide plate in the direction from the inner wall to the outer wall, and the corresponding fixed guide plate protrudes with an arc-shaped part to match the notch, so that after the rotating guide plate rotates, the inner wall still maintains a smooth transition with the fixed guide plate, minimizing the additional resistance to the air volume generated by the rotation of the rotating guide plate to ensure the smooth flow of the air volume.

Detailed implementation mode

[0037] Embodiment 1:

[0038] Please refer to Figures 1-13 As shown in Figures 1-3 , the present invention provides a technical solution: As shown in

[0039] , a silent ceiling heating device includes a box body 1 and a box cover 2 connected by screws. One side inside the box body 1 is fixedly connected with a hot air module 3, and the other side is provided with an air exhaust port 11. An air outlet assembly 5 is installed between the air exhaust port 11 and the hot air module 3 to convey the generated air volume to the hot air module 3 to heat the air volume and discharge it into the room or convey it to the air exhaust port 11 to discharge it to the outside. A control center 4 is fixedly connected to one side of the box body 1 near the air exhaust port 11 for controlling the hot air module 3 and the air outlet assembly 5; A pair of rotating structures 6 are installed on the outer wall of the air outlet assembly 5 for controlling the air volume conveyed to the air exhaust port 11; An air exhaust duct 12 is fixedly connected to the outside of the air exhaust port 11 for connecting with an external pipeline.

[0039] The air outlet assembly 5 includes a pair of first motors 51, a pair of wind wheels 52 and a pair of guide plates 53. The wind wheels 52 are fixedly connected to the first motors 51 and rotate with the first motors 51 to generate air volume. The guide plates 53 are located outside the wind wheels 52. The guide plates 53 are preferably in the shape of a volute. The opposite ends of the pair of guide plates 53 are fixedly connected to both sides of the hot air module 3, and the opposite ends are bent and fixedly connected to form a guiding channel 531 for air volume flow, which can increase the air volume flowing from the wind wheels 52 to the hot air module 3 and also help to disperse the flow direction of the air volume, avoiding the air volume being too concentrated, resulting in noise when blowing towards the hot air module 3 and air volume loss; The air volume generated by the wind wheels 52 flows through the guiding channel 531 to the hot air module 3 and is discharged into the room after being heated by the hot air module 3.

[0040] Inside the guide plate 53, a straight flow guide plate 532 and a bent flow guide plate 533 are fixedly connected to further forcibly divide the air volume, enabling the air volume to flow towards the hot air module 3 relatively evenly. Among them, the bent flow guide plate 533 bends towards the direction of the bent guide plate 53, which can guide the air volume to flow towards the middle of the hot air module 3. The straight flow guide plate 532 is away from the bent guide plate 53, which can forcibly make part of the air volume flow towards both sides of the hot air module 3. In this way, the entire hot air module 3 can heat the air volume, and the heating is more uniform, fully reaching the heating temperature, thereby achieving a better heating effect indoors. The dispersion of the air volume also reduces the impact force generated by the air volume, effectively avoiding the impact force when the air volume blows towards the hot air module 3, reducing the generation of noise, making the air volume flowing into the room more uniform, and providing a better and more comfortable user experience. The ends of the straight flow guide plate 532 and the bent flow guide plate 533 close to the wind wheel 52 are conical to reduce wind resistance and air volume loss.

[0041] On the outer walls of the opposite sides of the guide plate 53, a sound-absorbing component 54 is fixedly connected. The sound-absorbing component 54 includes a pair of stabilizing plates 541, a pair of fixing plates 542, and two groups of sound guide tubes 543. The pair of stabilizing plates 541 are attached to the outer walls of the pair of opposite guide plates 53, located between the bent guide plate 53 and the rotating structure 6. One end of the fixing plate 542 is fixedly connected to the bent guide plate 53, and the other end is fixedly connected to the outer wall near the end of the stabilizing plate 541. There is a gap between the stabilizing plate 541 and the fixing plate 542, and a group of sound guide tubes 543 are fixedly connected between the stabilizing plate 541 and the fixing plate 542. The sound guide tubes 543 penetrate through the stabilizing plate 541 and the fixing plate 542. The pair of fixing plates 542 and the pair of opposite bent guide plates 53 enclose a sound-absorbing cavity, and sound-absorbing cotton 536 is provided in the sound-absorbing cavity. The closer the wind wheel 52 is to the inner wall of the guide plate 53, the more likely it is to generate noise when the air volume blows towards the inner wall of the guide plate 53. The noise generated when the air volume blows towards the inner wall of the guide plate 53 can be transmitted to the sound-absorbing cavity through the sound guide tubes 543 and then absorbed by the sound-absorbing cotton 536, achieving the effect of noise reduction and silencing.

[0042] As Figures 4-6 shown, the guide plate 53 includes a fixed guide plate 534 and a rotating guide plate 535. The ends of the fixed guide plate 534 and the rotating guide plate 535 fit together. The rotating guide plate 535 is close to the air outlet 11, and the rotating guide plate 535 is fixedly connected to the rotating structure 6. The rotating structure 6 drives the rotating guide plate 535 to rotate towards the air outlet 11, and part of the air volume generated by the wind wheel 52 can flow towards the air outlet 11. Conversely, when the rotating guide plate 535 fits with the fixed guide plate 534, no air is exhausted.

[0043] The rotating structure 6 includes a rotating component 61, a driving component 62, a positioning component 63 and a lifting component 64. The rotating component 61 is fixedly connected to the end of the rotating guide plate 535. The positioning component 63 is fixedly connected to the middle part of the outer wall of the rotating guide plate 535. The driving component 62 is meshed with the rotating component 61. By moving the driving component 62, the rotating component 61 is driven to rotate. The rotating component 61 drives the rotating guide plate 535 and the positioning component 63 to rotate. In this way, through the matching of the positioning component 63 and the lifting component 64, the rotating guide plate 535 is fixed to prevent the rotating guide plate 535 from shaking. The positioning component 63 includes a positioning plate 631 and a positioning part 632 with a hollow middle. The positioning part 632 is fixedly connected to the end of the positioning plate 631 close to the rotating guide plate 535, and the end of the positioning plate 631 away from the rotating guide plate 535 is bent.

[0044] The rotating component 61 includes a rotating shaft 611 and fixing parts 612 fixedly connected to the outer walls of the upper and lower parts of the rotating shaft 611. A clamping tooth is provided in the middle of the rotating shaft 611. The rotating shaft 611 is rotatably connected to the box body 1. An annular groove 6121 is opened in the fixing part 612 close to the bottom of the box body 1. The fixing part 612 is fixedly connected to the rotating guide plate 535. By rotating the rotating shaft 611, the fixing part 612 is driven to rotate, and the fixing part 612 drives the rotating guide plate 535 to rotate. The rotation angle is a fixed angle, preferably 15 degrees or 30 degrees (in this embodiment, the rotation angle of the rotating guide plate 535 on the left side is 15 degrees, and the rotation angle of the rotating guide plate 535 on the right side is 30 degrees).

[0045] As Figures 7-8 shown, at the connection between the rotating guide plate 535 and the fixing part 612, an arc-shaped notch is opened from the inner wall to the outer wall of the rotating guide plate 535. The corresponding fixing guide plate 534 protrudes with an arc-shaped part 5341 to match the arc-shaped notch. When the rotating guide plate 535 rotates, the arc-shaped notch can rotate along the inner and outer walls of the arc-shaped part 5341, so that when the rotating guide plate 535 rotates and after the rotation is completed, its inner wall still maintains a smooth transition with the inner wall of the fixing guide plate 534 (see Figure 8 ), to ensure the smooth flow of the air volume.

[0046] As Figure 6 and Figures 9-12As shown, the driving component 62 includes a second motor 621, a driving plate 622, and a pressing plate 623. The driving plate 622 protrudes near one side of the rotating guide plate 535 and has racks in some areas that are engaged with the gear teeth of the rotating shaft 611. The other side is engaged with the second motor 621. The driving plate 622 is slidably connected to the bottom of the box body 1. By rotating the second motor 621, the driving plate 622 is driven to move, so as to drive the rotating shaft 611 to rotate. The total length of the racks is sufficient for the rotating shaft 611 to drive the rotating guide plate 535 to rotate by 15 degrees or 30 degrees; the pressing plate 623 is fixedly connected to the side of the driving plate 622 close to the rotating guide plate 535 and matches the annular groove 6121, and can pass through the annular groove 6121 along with the movement of the driving plate 622. One side of the pressing plate 623 close to the bottom of the box body 1 presses against the lifting component 64; when the rotating guide plate 535 fits with the fixed guide plate 534, the end of the driving plate 622 away from the rotating guide plate 535 abuts against the bent part of the positioning plate 631 (see Figure 4 ), ensuring the stability of the rotating guide plate 535.

[0047] The lifting component 64 includes a telescopic block 641, a telescopic plate 642, and a limiting part 643. The telescopic block 641 is fixedly connected to the bottom of the box body 1. The telescopic plate 642 is slidably connected to the middle of the telescopic block 641. The limiting part 643 is L-shaped. The outer sides of the limiting part 643 are parallel to the pressing plate 623 and the telescopic plate 642 respectively, and are fixedly connected to the side surface of the telescopic plate 642 respectively, aligned with one end of the pressing plate 623 close to the rotating shaft 611. The end of the limiting part 643 parallel to the pressing plate 623 protrudes to form a slope (see Figure 10 ). Part of the other end of the pressing plate 623 is hollowed out to match the sloped end of the limiting part 643. The distance of the non-hollowed part of the pressing plate 623 is greater than or equal to the distance that the driving plate 622 moves when the rotating shaft 611 drives the rotating guide plate 535 to rotate by 15 degrees or 30 degrees. When the pressing plate 623 moves in the direction away from the air outlet 11 following the driving plate 622, the pressing plate 623 will move accordingly until the sloped end moves to the hollowed-out part at the other end of the pressing plate 623. At this time, the telescopic plate 642 drives the limiting part 643 to move in the direction of the hollowed-out part at the other end of the pressing plate 623 under the action of gravity until the sloped end matches the hollowed-out part. At this time, the telescopic plate 642 is inserted into the positioning part 632 to position the rotating guide plate 535. At this time, the guiding channel 531 communicates with the air outlet 11 (see Figure 12 , the gray part in the figure is the part where the positioning plate 631 is blocked by the exhaust air cylinder 12), and the air volume can flow to both the hot air module 3 and the air outlet 11 at the same time; when the rotating guide plate 535 fits with the fixed guide plate 534, or at the positions where it rotates by 15 degrees or 30 degrees, rubber is provided at the bottom of the box body 1 and the inner wall of the box cover 2 ( Figure 2 the dotted line at the bottom of the box body 1 in the figure is the position of the rubber), which can seal the gaps on both the upper and lower sides of the rotating guide plate 535 to prevent the air volume from flowing into the gaps and generating noise.

[0048] When the rotation angle of the rotating guide plate 535 is 30 degrees, the lifting assembly 64 is closer to the driving plate 622 by 15 degrees of rotation. When the rotating guide plate 535 rotates 30 degrees, it will occupy part of the position of the driving plate 622, causing the driving plate 622 to make an adaptive adjustment. A notch is provided at one end of the driving plate 622 away from the rotating guide plate 535 ( Figure 13 The dotted line indicates the notch part of the driving plate 622), and the notch is close to the bottom of the box body 1, leaving an installation position for the lifting assembly 64.

[0049] Working principle: The user starts the first motor 51, and the first motor 51 drives the wind wheel 52 to rotate to generate air volume, which flows along the guiding channel 531 to the hot air module 3. After being forced to branch by the guiding straight plate 532 and the guiding folding plate 533, the air volume can flow relatively evenly to the entire hot air module 3, avoiding the air volume being concentrated on a certain part of the hot air module 3, resulting in the air volume not being able to quickly flow into the room, thereby generating noise. Finally, after being heated by the hot air module 3, it flows into the room; a part of the air volume generated by the wind wheel 52 will directly blow against the inner wall of the guide plate 53, thereby generating noise. The noise is transmitted to the sound-absorbing cotton 536 through the sound guide tube 543 and is absorbed by the sound-absorbing cotton 536 to reduce the noise;

[0050] When exhaust is required, the user starts the second motor 621, and the second motor 621 drives the driving plate 622 to move in a direction away from the exhaust port 11. The driving plate 622 drives the rotating shaft 611 to rotate, and the rotating shaft 611 drives the fixing part 612 and the rotating guide plate 535 to rotate towards the exhaust port 11. After the rotating guide plate 535 rotates 15 degrees, at this time, the telescopic plate 642 and the hollow part of the positioning part 632 are located in the same vertical direction. At this time, the sloped end of the limiting part 643 does not match the hollow part at the other end of the pressing plate 623. The driving plate 622 continues to move. At this time, the driving plate 622 is no longer engaged with the rotating shaft 611 until the sloped end of the limiting part 643 matches the hollow part at the other end of the pressing plate 623, driving the telescopic plate 642 to extend and insert into the middle hollow part of the positioning part 632 to position the rotating guide plate 535, ensuring the stability of the rotating guide plate 535 and avoiding noise generated by shaking caused by the blowing of the air volume (during actual installation, it is installed upside down, that is, the box cover 2 faces the ground. Therefore, the pressing plate 623 is closer to the ground than the limiting part 643, and the telescopic plate 642 can extend and insert into the middle of the positioning part 632 under its own gravity); the operation of rotating the rotating guide plate 535 by 30 degrees is the same as above; the user can, according to the usage requirements, rotate one of the rotating guide plates 535 by 15 degrees, or rotate the other rotating guide plate 535 by 30 degrees, or open both rotating guide plates 535 for exhaust;

[0051] After use, the second motor 621 rotates in the reverse direction, driving the drive plate 622 to move towards the direction close to the air outlet 11. As the drive plate 622 moves, the pressing plate 623 forces the telescopic plate 642 to gradually move towards the bottom of the box body 1 until the telescopic plate 642 disengages from the positioning portion 632. The drive plate 622 continues to move and begins to resume meshing connection with the rotating shaft 611. The rotating shaft 611 drives the positioning portion 632 and the rotating guide plate 535 to move away from the air outlet 11 until they fit with the fixed guide plate 534. At this time, the end of the drive plate 622 abuts against the bent portion of the positioning plate 631 to ensure the stability of the rotating guide plate 535.

[0052] Embodiment 2

[0053] Based on the above embodiment, as Figure 11 shown, at least one support column 71 is provided between the limiting portion 643 and the bottom of the box body 1. One end of the support column 71 is fixedly connected to the bottom of the box body 1, and the other end is slidably connected with a downward pressure rod 72. The downward pressure rod 72 is used to abut against the limiting portion 643. When the sloped end of the limiting portion 643 matches the hollow portion of the pressing plate 623, the gravity brought by the downward pressure rod 72 can assist the limiting portion 643 to drive the telescopic plate 642 to move towards the positioning portion 632 to ensure that the telescopic plate 642 is inserted into the positioning portion 632. The downward pressure rod 72 is made of a weight-bearing material such as metal.

[0054] Embodiment 3

[0055] Based on the above embodiment, a spring is provided at the end of the telescopic plate 642 located inside the telescopic block 641.
