Description

Technical Field

[0001] This invention relates to the technical field of bathroom heaters, and in particular to a swing structure and a bathroom heater. Background Technology

[0002] Traditional bathroom heaters often use a dynamic oscillating blade structure to adjust the airflow direction. The dynamic oscillating blade structure is generally composed of oscillating blades and a stepper motor. The stepper motor drives the rotation of the oscillating blades to achieve airflow.

[0003] However, the diameter of a conventional stepper motor is generally 24mm or 28mm, and its installation size is generally 31mm-35mm. Due to its installation size limitation, the size of a typical oscillating blade air outlet is usually 50mm, which cannot be used in bathroom heaters with ultra-narrow air outlets and cannot meet the needs of modern minimalist design. In addition, the dynamic oscillating blade structure will take up space in the air duct outlet position and affect the uniformity of air output. Summary of the Invention

[0004] Therefore, it is necessary to address the problem that the current swing structure cannot adapt to extremely narrow air outlets and has relatively poor air uniformity, and to provide a swing structure and bathroom heater that can be adapted to extremely narrow air outlets and has more uniform air distribution.

[0005] This application first provides a swing structure, including an air outlet duct and a partition.

[0006] The air outlet duct includes a columnar main air duct section and an air outlet section. The main air duct section is connected to the air outlet section in its own radial direction. The air outlet section has an air outlet opening in the radial direction. The cross-sectional area of ​​the air outlet section in the YOZ plane gradually decreases in the direction close to the air outlet.

[0007] The separator is fixed inside the air outlet duct. The separator extends along the X-axis to divide the main air duct section and the air outlet section into two independent air paths. The inner wall of the air path located inside the air outlet section forms a guide surface. The guide surface is configured to guide the airflow of the two air paths to converge at the air outlet position.

[0008] In one embodiment, the swing structure further includes an air volume regulating component, which is disposed in or upstream of the air outlet duct and is used to control the air intake ratio of the two air paths (a).

[0009] In one embodiment, the air outlet duct further includes an adjustment box, one end of the main air duct section along its own axial direction is connected to the adjustment box, and the air volume adjustment component is disposed inside the adjustment box.

[0010] In one embodiment, the airflow regulating component includes a motor, a rotating shaft, and a partition. The motor is fixed inside the regulating box, the rotating shaft extends along the Y-axis and one end is fixed to the output end of the motor, and the partition is fixed to the rotating shaft.

[0011] In one embodiment, a motor protection box is fixed to the inner wall of the adjustment box away from the air outlet, the motor is fixed inside the motor protection box, and the rotating shaft passes through the motor protection box.

[0012] In one embodiment, the air outlet section is strip-shaped and arranged axially along the main air duct section, with both ends of the air outlet section flush with both ends of the main air duct section in the axial direction.

[0013] In one embodiment, one end of the separator along the Y-axis is fixed to the inner wall of the main air duct section and extends into the air outlet section.

[0014] In one embodiment, the separator includes a separator plate and a flow guide. One end of the separator plate is fixed to the inner wall of the main air duct section, and the other end is fixed to the flow guide. The flow guide is located in the air outlet section and has a triangular cross-section along the YOZ plane, with one corner of the triangle facing the air outlet.

[0015] In one embodiment, the corner of the air guide facing the air outlet is rounded.

[0016] In one embodiment, the two sets of guide surfaces are symmetrically arranged with respect to the guide member.

[0017] In one embodiment, the inner wall of the air outlet section is a plane, and its tilt angle α ranges from 20° to 35°.

[0018] In one embodiment, the width of the air outlet along the Y-axis is less than or equal to 30 mm.

[0019] A second aspect of this application provides a bathroom heater, including a housing, a fan, and the aforementioned swing structure. The fan is disposed inside the housing, the swing structure is disposed on the side of the housing, and the air inlet of the regulating box is connected to the outlet of the fan.

[0020] In one embodiment, the air inlet is arranged along the radial direction of the fan, and the air outlet is arranged along the axial direction of the fan.

[0021] In one embodiment, the fan has two outlets, and two sets of swing structures are provided on both sides of the housing, which are respectively connected to the two outlets of the fan.

[0022] The above-mentioned swing structure decouples the traditional dynamic swing blade structure from static to dynamic. The two sets of guide surfaces formed by the inner wall of the air outlet section and the top of the separator serve as static airflow guiding structures, only undertaking the function of airflow turning. This functional separation effectively reduces the volume of the swing structure, making it suitable for machines with extremely narrow air outlets. Furthermore, the airflow direction can be controlled by controlling the air volume within the two sets of guide surfaces.

[0023] The guide surfaces formed within the two independent air paths can guide the two airflows to converge. It is easy to understand that the greater the difference in the air intake of the two air paths, the closer the direction of the converging airflow will be to the airflow direction of the air path with the larger air intake. Therefore, the direction of the converging airflow can be adjusted by adjusting the ratio of the air intake of the two air paths.

[0024] The static airflow guiding structure uses the inner wall of the air outlet section as a guiding surface, so that the airflow of the two air paths converges at the air outlet position. That is, the air outlet position can be reused by the two air paths, achieving the effect of saving space. At the same time, the tapered guiding surface and the airflow adhesion effect work together to improve the deflection efficiency. Attached Figure Description

[0037] For ease of description, in this application, the length direction of the main air duct section 12 is defined as the X-axis direction, the width direction of the air outlet 13a is defined as the Y-axis direction, and the outlet orientation of the air outlet 13a is defined as the Z-axis direction. The X-axis, Y-axis, and Z-axis directions are perpendicular to each other.

[0038] Please combine Figure 1 as well as Figure 2 As shown, this application first provides a swing structure, including an air outlet duct 10 and a partition 30. The air outlet duct 10 includes a main air duct section 12 and an air outlet section 13. The main air duct section 12 is connected to the air outlet section 13. An air outlet 13a is provided on the side of the air outlet section 13 away from the main air duct section 12. The cross-sectional area of ​​the air outlet section 13 along the YOZ plane gradually decreases in the direction close to the air outlet 13a.

[0039] The separator 30 is fixed inside the air outlet duct 10. The separator 30 extends along the X-axis to divide the main air duct section 12 and the air outlet section 13 into two independent air paths 10a. The inner wall of the air path 10a located inside the air outlet section 13 forms a guide surface. The guide surface is configured to guide the airflow of the two air paths 10a to converge at the air outlet 13a.

[0040] The swing structure of this application decouples the traditional dynamic swing blade structure from static to dynamic. The two sets of guide surfaces formed by the inner wall of the air outlet section 13 and the top of the separator 30 serve as static airflow guiding structures, only undertaking the function of airflow turning. By separating functions, the volume of the swing structure is effectively reduced, making it suitable for machines with extremely narrow air outlets. On this basis, the airflow direction can be controlled by controlling the air volume in the two sets of guide surfaces.

[0041] Specifically, the guide surfaces formed within the two independent air paths 10a can guide the two airflows to converge. It is easy to understand that the greater the difference in the air intake volume between the two air paths 10a, the closer the direction of the converging airflow will be to the airflow direction of the air path 10a with the larger air intake volume. Therefore, the direction of the converging airflow can be adjusted by adjusting the ratio of the air intake volume of the two air paths 10a.

[0042] More specifically, the static airflow guiding structure uses the inner wall of the air outlet section 13 as a guiding surface so that the airflow of the two air paths 10a converges at the air outlet 13a. That is, the air outlet 13a can be reused by the two air paths 10a, achieving the effect of saving space. At the same time, the tapered guiding surface and the airflow adhesion effect work together to improve the deflection efficiency.

[0043] It is worth mentioning that the design of the main air duct section 12 and the air outlet section 13 has two aspects. First, the air outlet 13a is distributed in a long strip along the X-axis direction so that the air outlet can cover a wider area in the X-axis direction, which helps to distribute the air volume evenly. Second, the flow cross-section of the air path 10a in the air outlet section 13 is smaller than that in the air path 10a in the main air duct section 12, so that the airflow velocity at the air outlet 13a can be increased by utilizing the Venturi effect.

[0044] Preferably, the main air duct section 12 is columnar, that is, the axial direction of the main air duct section 12 is its length direction, which is the X-axis direction, and the radial direction of the main air duct section 12 is the Z-axis direction, so that the airflow direction in the main air duct section 12 is perpendicular to the airflow direction in the outlet section 13.

[0045] It should be understood that in some other embodiments, the main air duct section 12 may also be of other shapes, which will not be listed here.

[0046] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the swing structure further includes an air volume adjustment component 20, which is disposed in the air outlet duct 10 or upstream of the air outlet duct 10, and is used to control the air volume ratio of the two air paths 10a.

[0047] As a dynamic adjustment structure, the air volume adjustment component 20 can adjust the air volume ratio of the two air paths 10a. Specifically, the air volume adjustment component 20 can be set between the two air paths 10a to directly change the air volume ratio of the two air paths 10a, or it can be set in one of the air paths 10a, so that the air volume ratio of the two air paths 10a can be adaptively changed by changing the air volume of that air path 10a.

[0048] Of course, in other embodiments, the air intake volume of the swing structure of this application can also be changed in other ways, such as the two air intake volumes of ...

[0049] Please combine Figure 1 as well as Figure 2As shown, in some embodiments, the air outlet duct 10 further includes an adjustment box 11, one end of the main air duct section 12 along its own axial direction is connected to the adjustment box, and the air volume adjustment component 20 is disposed in the adjustment box 11.

[0050] By placing the air volume adjustment component 20 inside the adjustment box 11, that is, moving the dynamic adjustment structure forward and placing it upstream of the main air duct section 12, on the one hand, the upstream space is effectively utilized through functional separation, which improves the uniformity of air outlet and is applicable to machines with extremely narrow air outlets. On the other hand, the adjustment box 11 is far from the outside world, so that the air volume adjustment component 20 is not directly exposed to the outside world, effectively improving its service life.

[0051] It should be noted that the presence of the static airflow guiding structure enables the swing structure of this application to achieve functional separation, thereby allowing the air volume adjustment component 20 to be placed in front (located upstream of the main air duct section 12), avoiding the situation where the mechanical structure occupies the space of the air outlet 13a, which would affect the uniformity of the air outlet, and effectively improving the uniformity of the air outlet of the swing structure of this application.

[0052] Please combine Figure 1 , Figure 3 as well as Figure 4 As shown, in some embodiments, the air volume regulating component 20 includes a motor 21, a rotating shaft 22 and a partition 23. The motor 21 is fixed inside the regulating box 11, the rotating shaft 22 extends along the Y-axis and one end is fixed to the output end of the motor 21, and the partition 23 is fixed to the rotating shaft 22.

[0053] The rotation of baffle 23 can change the air intake volume of the two air passages 10a, thereby changing the deflection vector of the two airflows along the Y-axis at the outlet 13a. It is easy to understand that when the deflection vectors of the two airflows along the Y-axis at the outlet 13a are the same, the deflection vectors cancel each other out, and the converging airflow is blown out along the Z-axis. Otherwise, the converging airflow will deflect in the direction with the larger deflection vector. Thus, the airflow angle is adjusted by adjusting the angle of baffle 23.

[0054] Please refer to Figure 2 As shown, preferably, the two sets of guide surfaces are symmetrically arranged with the separator 30 as the center to facilitate the adjustment of the airflow direction.

[0055] Specifically, in the initial state, please refer to Figure 4 As shown, the baffle 23 is in the middle state. At this time, the airflow entering the air outlet duct 10 through the air inlet 11b is evenly divided into two parts by the baffle 23. That is, the air volume entering the two airways 10a is the same. The two airflows with the same air volume converge at the air outlet 13a and cancel each other out along the Y-axis direction. Finally, the converged airflow is blown out vertically along the Z-axis direction.

[0056] When the swing function is activated, motor 21 starts and drives partition 23 to rotate reciprocally via shaft 22. After motor 21 drives partition 23 to rotate a certain angle ( Figures 4 to 3 (In the intermediate state between), the air intake of the left air passage 10a decreases, while the air intake of the right air passage 10a increases. The air volumes of the two airflows are different. Therefore, when the two airflows converge at the outlet 13a, the deflection vectors along the Y-axis cannot completely cancel each other out. The converged airflow still has a deflection vector to the right along the Y-axis, that is, the converging airflow deflects to the right, but the deflection angle is smaller than the guiding angle of the right guide surface.

[0057] When motor 21 further drives partition 23 to Figure 3 When the position is such that the left air passage 10a is completely closed, the intake airflow completely enters the right air passage 10a, and therefore the airflow flowing out along the outlet 13a deflects to the left, and the deflection angle is the same as the guiding angle of the left guide surface.

[0058] In some other embodiments, the air volume regulating component 20 may also have other structures, such as a partition that moves or rotates along the ZOY plane to change the air volume of the two air paths 10a, which will not be described in detail here.

[0059] In some other embodiments, a set of airflow adjustment components 20 may be provided for each airflow path 10a, so that the airflow of the two airflow paths 10a can be adjusted independently, thereby further improving the degree of adjustment freedom to meet the needs of more scenarios.

[0060] Please combine Figure 1 , Figure 3 as well as Figure 4 As shown, in some embodiments, a motor protection box 11a is fixed to the inner wall of the regulating box 11 on the side away from the air outlet 13a, and the motor 21 is fixed inside the motor protection box 11a and the rotating shaft 22 passes through the motor protection box 11a, thereby achieving the effect of reducing the failure rate of the motor 21.

[0061] Because the ambient humidity at the air outlet 13a is high, there is a risk of corrosion and jamming of the motor 21 after long-term use. In this application, the regulating box 11 is relatively far away from the air outlet 13a, and the regulating box 11 is also equipped with a motor protection box 11a that is far away from the air outlet 13a. By placing the motor 21 inside the motor protection box 11a, the operating environment can be kept dry, thereby effectively extending the service life of the motor 21 and reducing the failure rate.

[0062] Please refer to Figure 1 As shown, in some embodiments, the air outlet section 13 is strip-shaped and arranged along the axial direction of the main air duct section 12. The two ends of the air outlet section 13 are flush with the two ends of the main air duct section 12 in the axial direction, so that the air outlet can cover a wider area in the X-axis direction, which helps to distribute the air volume evenly.

[0063] Please refer to Figure 2 As shown, in some embodiments, the separator 30 is fixed to the inner wall of the main air duct section 12 and extends into the air outlet section 13. The separator 30 includes a separator plate 30a and a guide 30b. One end of the separator plate 30a is fixed to the inner wall of the main air duct section 12, and the other end is fixed with the guide 30b. The guide 30b is located in the air outlet section 13 and its cross-section along the YOZ plane is triangular, with one corner of the triangle facing the air outlet 13a. The surface of the triangular guide 30b can cooperate with the inner wall of the air outlet section 13 to form a guiding surface, using the Coanda effect to guide the airflow direction.

[0064] Of course, in other embodiments, the guide member 30b may also have other structures and shapes. The surface of the guide member 30b may be a plane or a curved surface, as long as the guide member 30b can separate the two air paths 10a and form a guide surface with the inner wall of the air outlet section 13. This application does not make any further limitations here.

[0065] Please refer to Figure 2 As shown, preferably, one corner of the guide member 30b facing the air outlet 13a is rounded. The rounded corner of the guide member 30b can delay the boundary layer separation caused by the collision between the airflow and the guide surface, and reduce the generation of eddies.

[0066] Please refer to Figure 2 As shown, in some embodiments, the inner wall of the air outlet section 13 is a plane, and its tilt angle α ranges from 20° to 35°.

[0067] If the tilt angle α is too large, the airflow in the wind path 10a may detach from the guide surface, thus failing to guide the momentum vector deflection of the airflow. Furthermore, the deflection vectors of the two airflows along the Y-axis are large, and most of the airflow will be lost due to the collision and convergence of the two airflows, resulting in insufficient output airflow of the final converging airflow. On the other hand, if the tilt angle α is too small, the maximum deflection angle of the final output airflow will be small, which cannot meet the normal swing requirements. Moreover, the length of the wind path 10a needs to be increased to achieve the equivalent deflection angle under the condition of a large tilt angle α, which will lead to an increase in the thickness of the swing structure.

[0068] Preferably, the inclination angle α of the inner wall of the air outlet section 13 relative to the axis of the air outlet 13a is 27°.

[0069] Of course, in some other embodiments, the inner wall of the air outlet section 13 may also be curved, as long as its cross-sectional area gradually decreases along the direction close to the air outlet 13a and can play the role of guiding airflow. This application will not go into detail here.

[0070] Please refer to Figure 2 As shown, in some embodiments, the inner wall of the air outlet section 13 is parallel to the side wall of the guide member 30b to optimize the airflow guiding effect.

[0071] In some embodiments, the width of the air outlet 13a along the Y-axis is less than or equal to 30 mm; preferably, the width of the air outlet 13a along the Y-axis is in the range of 15 mm to 30 mm, so as to simultaneously meet the requirements of air volume and extremely narrow appearance design.

[0072] Please refer to Figure 5 As shown, the second aspect of this application provides a bathroom heater, including a housing 100, a fan 200 and the aforementioned swing structure. The fan 200 is disposed inside the housing 100, the swing structure is disposed on the side of the housing 100, and the regulating box 11 has an air inlet 11b connected to the outlet of the fan 200 along the axial direction of the main air duct section 12.

[0073] Please combine Figure 1 as well as Figure 5 As shown, in some embodiments, the air inlet 11b is arranged along the radial direction of the fan 200, and the air outlet 13a is arranged along the axial direction of the fan 200. The structure is relatively compact, which can effectively improve the space utilization rate inside the housing 100, reduce the thickness of the bathroom heater, and improve the appearance.

[0074] Please refer to Figure 5 As shown, in some embodiments, the fan 200 has two outlets, and two sets of swing structures are provided on both sides of the housing 100, which are respectively connected to the two outlets of the fan 200 to further increase the air outlet range.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
