Description

Technical Field

[0001] This disclosure relates to the field of heating device technology, and in particular to an air outlet structure, a method for adjusting the air outlet angle, and a heater. Background Technology

[0002] 360° circular airflow heaters are becoming increasingly popular, but these heaters lack oscillation functionality and cannot adjust the airflow angle. Airflow within the housing is directed vertically after passing through the circular airflow structure. Another approach involves a circular airflow assembly with two ducts. The airflow from these two ducts merges in a mixing cavity before flowing to the circular outlet. While this improves airflow uniformity, the inability to adjust the airflow angle results in a limited airflow range, leading to unsatisfactory heating and a poor user experience. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this disclosure provides an air outlet structure with an adjustable air outlet angle and good heating effect, a method for adjusting the air outlet angle, and a heater.

[0004] The first aspect of this disclosure provides an air outlet structure, including:

[0005] The housing is fixedly installed in the box and is circular in shape. An air guide plate is provided between the center of the housing and the box. The air guide plate is adapted to the circular housing and is set close to the housing. A first air inlet is provided on the air guide plate.

[0006] A cover body, which is fixedly connected to the housing;

[0007] A flow guide layer is disposed between the shell and the cover. A second air inlet is provided on the flow guide layer at a position corresponding to the first air inlet. An annular first air duct is formed between the flow guide layer and the shell, and an annular second air duct is formed between the flow guide layer and the cover. The first air duct and the second air duct have different air outlet directions.

[0008] A driving component drives the air guide plate to rotate to partially block the second air inlet, thereby adjusting the airflow of the first air duct and the second air duct.

[0009] In some embodiments, the area of ​​the first air inlet is greater than or equal to the area of ​​the second air inlet, and the first air inlet and the second air inlet have the same shape and are polygonal.

[0010] In some embodiments, the flow guiding layer includes a first flow guiding surface and a second flow guiding surface, and both the first flow guiding surface and the second flow guiding surface are convex surfaces;

[0011] The first airflow channel is formed between the first airflow guide surface and the shell, and the second airflow channel is formed between the second airflow guide surface and the cover.

[0012] In some embodiments, the airflow guiding layer further includes a first horn surface connected to the second airflow guiding surface, the first horn surface and the cover forming a second air outlet.

[0013] In some embodiments, the cover is cone-shaped, bulging towards the housing, and the cover includes a conical curved surface and a second flared surface;

[0014] The second horn surface and the first horn surface form a second air outlet, and the air outlet direction of the second air outlet has a second angle with the horizontal plane.

[0015] In some embodiments, the first horn surface and the housing form a first air outlet, and the air outlet direction of the first air outlet has a first angle with the vertical plane.

[0016] In some embodiments, the cross-sectional distance between the first air outlet and the second air outlet is 0.3cm to 2.5cm.

[0017] In some embodiments, the cone angle of the conical surface is less than 60°, the cone angle protrudes toward the second air inlet, and the cone angle and the second air inlet have a gap in the vertical direction.

[0018] In some embodiments, a first fixed base is provided at the bottom of the outer side of the housing, and the housing is installed in the box by fasteners passing through the first fixed base.

[0019] The second aspect of this disclosure provides a method for adjusting the air outlet angle of an air outlet structure, including:

[0020] The air guide plate is driven to rotate, and the area ratio of the first air inlet and the second air inlet is adjusted to change the air volume of the first air inlet and the second air inlet.

[0021] In some embodiments, changing the area ratio of the first air inlet and the second air inlet includes:

[0022] When the air guide plate is driven to rotate, the first air inlet rotates. When the long side of the first air inlet is parallel to the short side of the second air inlet, the area ratio of the first air inlet and the second air inlet is the largest. The air volume entering the first air duct increases, and the air volume entering the second air duct decreases, thereby increasing the angle at which air is blown out in the vertical direction and decreasing the angle at which air is blown out in the horizontal direction.

[0023] When the air guide plate is driven to rotate, the first air inlet rotates. When the long side of the first air inlet is parallel to the long side of the second air inlet, the area ratio of the first air inlet to the second air inlet is the smallest. The amount of air entering the first air duct decreases, and the amount of air entering the second air duct increases. This reduces the angle at which air is blown out in the vertical direction and increases the angle at which air is blown out in the horizontal direction.

[0024] This disclosure provides a heater that includes the air outlet structure described in any of the above embodiments, and further includes a housing, a panel, and a heater, wherein the panel is fixed to the housing, and the heater is disposed in the housing.

[0025] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0026] The air outlet structure provided in this embodiment achieves overall installation by fixing the housing within a box using a housing, a cover, a guide layer, and a driving component. The housing is annular, and a guide plate is provided between the center of the housing and the box. The guide plate fits the annular housing and is positioned close to the housing to prevent air from entering through gaps between the guide plate and the housing. A first air inlet is provided on the guide plate, which communicates with the air outlet of the box, allowing air from the box to enter the air outlet structure through the first air inlet. The cover is fixedly connected to the housing. The guide layer is positioned between the housing and the cover, and the guide layer has components corresponding to the first air inlet. A second air inlet is provided at the location. A first annular air duct is formed between the guide layer and the shell, and a second annular air duct is formed between the guide layer and the cover. The annular air outlet is achieved through the first and second annular air ducts. The air outlet directions of the first and second air ducts are different, which increases the area of ​​hot air blowing, improves the heating effect, and reduces wind resistance. By setting a driving component to drive the air guide plate to rotate, part of the second air inlet is blocked, which changes the area ratio of the first and second air inlets. This adjusts the air volume of the first and second air ducts, thereby adjusting the direction of the annular air outlet, expanding the blowing range, improving the heating effect, and enhancing user comfort.

[0037] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0038] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0039] Example 1:

[0040] refer to Figure 1 and Figure 2 As shown, some embodiments of this disclosure provide an air outlet structure, including a housing 1, a cover 4, a flow guide layer 2, and a drive component.

[0041] The shell 1 is fixedly installed in the box and is circular in shape. A guide plate 7 is provided between the center of the shell 1 and the box. The guide plate 7 is adapted to the circular shell 1 and is set close to the shell 1. A first air inlet 701 is opened on the guide plate 7. The cover 4 is fixedly connected to the shell 1. A guide layer 2 is provided between the shell 1 and the cover 4. A second air inlet 201 is opened on the guide layer 2 at the position corresponding to the first air inlet 701. A first annular air duct 3 is formed between the guide layer 2 and the shell 1, and a second annular air duct 5 is formed between the guide layer 2 and the cover 4. The air outlet directions of the first air duct 3 and the second air duct 5 are different. A driving component drives the guide plate 7 to rotate to block part of the second air inlet 201, thereby adjusting the air volume of the first air duct 3 and the second air duct 5.

[0042] Specifically, the shell 1 is fixed inside the box to enclose the air guide layer 2 and the cover 4, meaning the entire air outlet structure is fixed inside the box. The shell 1 is annular in shape, and an air guide plate 7 is provided between the center of the shell 1 and the box. The air guide plate 7 has the same size and shape as the inner circle of the annular shell 1, and it is positioned close to the shell 1. A first air inlet 701 is provided on the air guide plate 7, which is connected to the air outlet of the box. The air drawn in enters the first air inlet 701 through the air outlet of the box. The air enters the housing 1; the cover 4 is fixedly connected to the housing 1, and the cover 4 is used to conceal the internal components of the air outlet structure, improving the aesthetics of the heater; the guide layer 2 is located between the housing 1 and the cover 4, specifically, the guide layer 2 is fixedly connected to the housing 1 by screws passing through the screw post 101, or the guide layer 2 is fixedly connected to the cover 4 by screws. Of course, the fixing method is not unique; it can also be fixed by clips, or by a combination of screws and clips. The guide layer 2 is connected to the first air inlet. A second air inlet 201 is provided at the position corresponding to the first air inlet 701. The second air inlet 201 and the first air inlet 701 are connected to the air outlet of the box. A first annular air duct 3 is formed between the guide layer 2 and the shell 1, and a second annular air duct 5 is formed between the guide layer 2 and the cover 4. The first air duct 3 and the second air duct 5 have different air outlet directions. By setting two annular air ducts with different air outlet directions, the effect of annular air outlet is ensured. Moreover, the two air ducts have different air outlet directions. Compared with single-direction annular air outlet, the blowing area is expanded, the heating effect is improved, the wind resistance is reduced, and the user's comfort is improved. The driving component can drive the air guide plate 7 to rotate, so that part of the second air inlet 201 is blocked by the air guide plate 7, thereby changing the area ratio of the first air inlet 701 and the second air inlet 201, adjusting the air volume entering the first air duct 3 and the second air duct 5, achieving the effect of changing the air outlet angle, realizing the adjustment of the annular air outlet direction, expanding the blowing range, improving the heating effect and the user's comfort.

[0043] Further reference Figure 2 As shown, the area of ​​the first air inlet 701 is greater than or equal to the area of ​​the second air inlet 201, and the first air inlet 701 and the second air inlet 201 have the same shape and are polygonal. By limiting the area of ​​the first air inlet 701 to be greater than or equal to the area of ​​the second air inlet 201, airflow is allowed to enter both the first air duct 3 and the second air duct 5, achieving annular airflow from different directions. By setting the first air inlet 701 and the second air inlet 201 to have the same shape and be polygonal, it is ensured that when the air guide plate 7 rotates, part of the second air inlet 201 can be blocked by the air guide plate 7, thereby changing the area ratio of the first air inlet 701 and the second air inlet 201 and adjusting the airflow entering the first air duct 3 and the second air duct 5.

[0044] refer to Figure 1As shown, the airflow guiding layer 2 includes a first airflow guiding surface 202 and a second airflow guiding surface 203, both of which are convex. A first airflow duct 3 is formed between the first airflow guiding surface 202 and the shell 1, and a second airflow duct 5 is formed between the second airflow guiding surface 203 and the cover 4. By setting the airflow guiding layer 2 to be formed jointly by the first airflow guiding surface 202 and the second airflow guiding surface 203, both of which are convex, specifically, the first airflow guiding surface 202 protrudes towards the shell 1, and the second airflow guiding surface 203 protrudes towards the cover 4. The first airflow guiding surface 202 and the second airflow guiding surface 203 form cavities. This design reduces wind resistance and increases the airflow velocity. Furthermore, the first airflow guiding surface 202 forms the first airflow duct 3 between the shell 1, and the second airflow guiding surface 203 forms the second airflow duct 5 between the cover 4, achieving annular airflow from both airflow ducts. The structure is simple and easy to install.

[0045] Furthermore, the airflow guiding layer 2 also includes a first horn surface 204 connected to the second airflow guiding surface 203. The first horn surface 204 and the cover 4 form a second air outlet 501. The first horn surface 204 is a straight section. The first horn surface 204 and the cover 4 form the second air outlet 501, which is the air outlet of the second air duct 5. The first horn surface 204 can guide the air to diffuse further outward so that the warm air can wrap around the human body.

[0046] Furthermore, the cover 4 is cone-shaped and protrudes towards the shell 1. The cover 4 includes a cone-shaped curved surface 401 and a second horn surface 402. The second horn surface 402 and the first horn surface 204 form a second air outlet 501. The air outlet direction of the second air outlet 501 is provided with a second angle with the horizontal plane. Specifically, the cover 4 is a cone-shaped structure that bulges towards the shell 1, so that after the air enters through the second air inlet 201, it flows towards the cone angle of the cover 4 and can be dispersed and flowed in all directions under the cutting of the cone angle, thereby achieving uniform flow into the annular second air duct 5 and out through the second air outlet 501, so that the warm air can wrap around the human body and improve the user's comfort. The cover 4 includes a conical curved surface 401 and a second horn surface 402. The setting of the conical curved surface 401 effectively reduces wind resistance and increases the air outlet speed. The second horn surface 402 is also a straight section. The second horn surface 402 and the first horn surface 204 form the second air outlet 501 to guide the air outlet direction. Specifically, the second included angle is α.

[0047] Furthermore, the first horn surface 204 and the housing 1 form a first air outlet 301, and the air outlet direction of the first air outlet 301 has a first angle with the vertical plane. The first air outlet 301 is the air outlet of the first air duct 3. Air flows into the first air duct 3 through the first air inlet 701 and flows out from the first air outlet 301. The first angle is β, and the sum of the first angle β and the second angle α is not greater than 90°.

[0048] To ensure that wind energy flows smoothly from the first air outlet 301 and the second air outlet 501, the cross-sectional distance between the first air outlet 301 and the second air outlet 501 is 0.3cm to 2.5cm. Specifically, the distance between the first horn surface 204 and the second horn surface 402 is 0.3cm to 2.5cm, and the distance between the first horn surface 204 and the housing 1 is 0.3cm to 2.5cm.

[0049] refer to Figure 1 As shown, the cone angle of the conical surface 401 is less than 60°, and the cone angle protrudes towards the second air inlet 201, with a gap between the cone angle and the second air inlet 201 in the vertical direction. By limiting the cone angle to less than 60° and ensuring that the cone angle protrudes towards the second air inlet 201, the airflow after entering through the second air inlet 201 flows towards the cone angle and is dispersed in all directions under the cutting action of the cone angle. This achieves uniform airflow into the annular second air duct 5, resulting in uniform airflow from the second air outlet 501 in the circumferential direction, thus achieving annular all-around airflow. This allows warm air to surround the body, improving user comfort. The larger the cone angle, the more gentle the conical surface 401 becomes, which reduces the effect of cutting the airflow and reducing wind resistance. In other words, it cannot disperse the air entering the second air inlet 201 in time, resulting in uneven airflow from the second air outlet 501. By setting a vertical gap between the cone angle and the second air inlet 201, i.e., the cone angle does not protrude beyond the second air inlet 201, the air entering the air outlet structure can enter the first air duct 3 along the first air inlet 701, and the air entering the air outlet structure can enter the second air duct 5 along the second air inlet 201. This ensures that air is blown out from both air ducts in different directions, expanding the blowing area, improving the heating effect, and enhancing the user's experience and comfort. The fact that the cone angle does not protrude beyond the second air inlet 201 also prevents all the air from flowing into the first air duct 3 and out through the first air outlet 301, ensuring that the air can flow out in a circular pattern from different directions after passing through the air outlet structure, thus improving the heating effect and enhancing the user's comfort.

[0050] To securely mount the housing 1 within the enclosure, a first fixing base 6 is provided on the bottom outer side of the housing 1. The housing 1 is installed into the enclosure via fasteners that pass through the first fixing base 6. By placing the first fixing base 6 on the outside of the housing, installation is facilitated. Specifically, the fasteners are screws, and the housing 1 is installed into the enclosure via screws that pass through the first fixing base 6.

[0051] In summary, this embodiment also provides a method for adjusting the air outlet angle, including: driving the air guide plate 7 to rotate and adjusting the area ratio of the first air inlet 701 and the second air inlet 201 to change the air volume of the first air inlet 701 and the second air inlet 201.

[0052] Specifically, the change in the area ratio of the first air inlet 701 and the second air inlet 201 includes: driving the air guide plate 7 to rotate, the first air inlet 701 rotates, and when the long side of the first air inlet 701 is parallel to the short side of the second air inlet 201, the second air inlet 201 is partially blocked. At this time, the area ratio of the first air inlet 701 and the second air inlet 201 is the largest, the air volume entering the first air duct 3 increases, and the air volume entering the second air duct 5 decreases, thereby increasing the angle at which the air is blown out in the vertical direction and decreasing the angle at which the air is blown out in the horizontal direction.

[0053] When the drive guide plate 7 rotates, the first air inlet 701 rotates. When the long side of the first air inlet 701 is parallel to the long side of the second air inlet 201, the second air inlet 201 is not blocked, so that the area ratio of the first air inlet 701 and the second air inlet 201 is minimized. The air volume entering the first air duct 3 decreases, and the air volume entering the second air duct 5 increases, thereby reducing the angle at which the air is blown out in the vertical direction and increasing the angle at which the air is blown out in the horizontal direction.

[0054] In the above embodiments, both the first air inlet 701 and the second air inlet 201 are rectangular.

[0055] Example 2:

[0056] refer to Figure 3 and Figure 4 As shown, the air outlet structure of this embodiment differs from that of the air outlet structure of the above embodiment in that the installation position of the air guide plate 7 is different and the setting position of the first air inlet is different.

[0057] Specifically, the air guide plate 7 is installed on the air guide plate bracket 11. The air guide plate 7 can be fixed by the inner buckle 1102 on the air guide plate bracket 11. The outer periphery of the air guide plate bracket 11 is also provided with a second fixed base 1103. The first fixed base 6 and the second fixed base 1103 can be fixed to the housing with screws. A first air inlet is opened at the center of the housing 1. A first opening 702 is opened on the air guide plate 7 corresponding to the first air inlet. A second opening 1101 is opened on the air guide plate bracket 11 corresponding to the first air inlet. In order to drive the air guide plate 7 to rotate, the air outlet structure also includes a motor 8. The motor 8 is powered and signaled by the main control module. The motor 8 is fixed on the motor bracket 9. The motor bracket 9 is fixed to the cover plate of the housing with screws. The shaft of the motor 8 passes through the gear 10 for transmission. The gear 10 meshes with the air guide plate 7, and the air guide plate 7 can rotate with the gear 10.

[0058] Based on the above air outlet structure, a method for adjusting the air outlet angle can also be provided. For details, please refer to [reference needed]. Figure 7As shown, the first included angle is β, the second included angle is α, the area ratio of the first air inlet and the second air inlet 201 is k, the air volume of the first air outlet 301 can be represented by the function f(k), the air volume of the second air outlet 501 can be represented by the function g(k), the actual air volume has a coefficient n in the equivalent horizontal and vertical components, and the air volume vector at a certain cross section can be expressed as: the air volume vector of the first air outlet n(cosαf(k),sinαf(k)); the air volume vector of the second air outlet n(sinβg(k),cosβg(k)), then the mixed air volume vector can be expressed as n(cosαf(k)+sinβg(k),sinαf(k)+cosβg(k)). When the motor 8 is powered on, it drives the gear 10 to rotate, thereby rotating the air guide plate 7. When the short side of the first opening 702 on the air guide plate 7 is parallel to the long side of the second opening 1101 or the long side of the first air inlet (e.g.) Figure 4 As shown), k is the minimum value; when the long side of the first opening 702 on the air guide plate 7 is parallel to the long side of the second opening 1101 or the long side of the first air inlet (as shown), k is the minimum value; Figure 3 (As shown), k is the maximum value. The main control unit outputs and records the number of rotation steps of motor 8. The value of k is calculated by controlling the number of rotation steps of motor 8. When k is the minimum value, the maximum air outlet angle of the mixed air can be obtained according to the mixed air volume vector relationship n(cosαf(k)+sinβg(k),sinαf(k)+cosβg(k)). When k is the maximum value, the minimum air outlet angle of the mixed air can be obtained according to the mixed air volume vector relationship n(cosαf(k)+sinβg(k),sinαf(k)+cosβg(k)). By controlling motor 8 to make the air guide plate 7 continuously rotate or repeatedly rotate forward and reverse, the maximum and minimum swing angles can be changed.

[0059] Example 3:

[0060] The air outlet structure provided in this embodiment is the same as that in Embodiment 1. The difference is that the housing provided in this embodiment provides separate air passages for the first air passage 3 and the second air passage 5, and each air passage is controlled by a different fan.

[0061] For details, please refer to Figure 5 and Figure 6 As shown, the housing is provided with a first air passage 12 and a second air passage 13. A first fan 14 is provided in the first air passage 12 and a second fan 15 is provided in the second air passage 13. A first outlet 1201 is formed at the end of the first air passage 12 facing the air outlet structure, and a second outlet 1301 is formed at the end of the second air passage 13 facing the air outlet structure. The first outlet 1201 and the second air inlet 201 are connected, and the second outlet 1301 and the first air inlet 701 are connected.

[0062] Based on the above-mentioned housing configuration, a method for adjusting the air outlet angle can also be provided. By adjusting the rotation speed of the first fan 14 and the second fan 15, the air volume passing through the first air duct 3 and the second air duct 5 can be changed.

[0063] Specifically, the first fan 14 and the second fan 15 are either DC motors or AC motors. The DC motor's speed is changed by adjusting the current; the AC motor's speed is changed by a thyristor. Different current values ​​are set for the first fan 14 and the second fan 15: the first fan 14 is set to current A1, and the second fan 15 is set to current A2. Current A1 corresponds to speed n1, and current A2 corresponds to speed n2. The airflow of the first duct 3 can be represented by the function p(n1), and the airflow of the second duct 5 can be represented by the function p(n2). (Refer to...) Figure 7 As shown, the angle between the air outlet direction of the first air outlet 301 and the vertical plane is β, and the angle between the air outlet direction of the second air outlet 501 and the horizontal plane is α. The actual air volume has a coefficient n in both the horizontal and vertical components. The air volume vector of the first air outlet is n(cosαp(n1), sinαp(n1)); the air volume vector of the second air outlet is n(sinβp(n2), cosβp(n2)). The mixed air volume vector can then be expressed as n(cosαp(n1) + sinβp(n2), sinαp(n1) + cosβp(n2)). When n1 is maximum and n2 is minimum, the mixed air outlet angle is minimum; when n1 is minimum and n2 is maximum, the mixed air outlet angle is maximum. By setting different current levels through the main control module, the rotation speeds of the first fan 14 and the second fan 15 are different, causing the mixed air outlet angle to change. Of course, any other means that can change the current can be used.

[0064] Other embodiments of this disclosure provide a heater, including the air outlet structure of any of the above embodiments, and further including a housing, a panel, and a heater, wherein the panel is fixed to the housing, and the heater is disposed in the housing.

[0065] Specifically, the housing has an open accommodating space, where the air outlet structure and heater are located. The panel is located at the opening of the housing and is fixed to the housing with screws. Alternatively, it can be fixed by clips or a combination of screws and clips. To facilitate the installation of the air outlet structure on the panel, the panel has mounting holes. The mounting holes also have positioning elements along their circumferential direction. The positioning elements are suitable for abutting against the air outlet structure to position it. Specifically, the positioning elements abut against the cover 4.
