Abstract

The present disclosure provides an air outlet component and a bathroom heater, which belongs to the technical field of household appliances. The air outlet component includes a first air guide shell, an air guide cone and a driving mechanism. The first air guide shell has an air inlet, and the air inlet is connected to the first air outlet of the host. The air guide wall of the air guide cone is convex, the outer diameter of the first end of the air guide cone is smaller than the outer diameter of the second end of the air guide cone, and the first end of the air guide cone extends toward the inside of the first air guide shell. The driving mechanism is used to drive the air guide cone to swing. During the swinging of the air guide cone, the guiding direction of the wind by the air guide cone will change, and the air outlet direction of the air outlet component will change. Therefore, by periodically driving the air guide cone to swing, the blowing range of the air outlet component can be expanded. In addition, the air guide cone is convex outward, so that the air guide cone can guide the air outlet direction to be approximately the same as the direction of the central axis of the air guide cone, thereby making the air outlet direction of the air outlet component straighter and not too divergent, so that the wind blown out of the air outlet component is easier to land.

DETAILED DESCRIPTION

[0079] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0080] The terms used in the embodiments of the present disclosure are only used to explain the embodiments of the present disclosure, and are not intended to limit the present disclosure.

[0081] A bathroom heater is a device that is installed in the bathroom and blows warm air to provide heating when the user is bathing.

[0082] The blowing range of the bathroom heater in the related art is relatively narrow, which affects the user experience. In addition, the air outlet of the bathroom heater in the related art is fixed, which means that after the bathroom heater is installed in place, the blowing position of the bathroom heater is also fixed. If you want to adjust the blowing position of the bathroom heater, you must adjust the installation position of the bathroom heater, which is very cumbersome.

[0083] In view of the above technical problems, the present disclosure provides a bathroom heater. Figure 1-Figure 4 As shown, the bathroom heater includes a main unit 1, an air outlet component 2 and a panel 3. The main unit 1 has a first air outlet 110, and the panel 3 has a avoidance opening 30 at a portion opposite to the first air outlet 110. The air outlet component 2 is installed in the avoidance opening 30. When the bathroom heater is working, the wind blown out from the first air outlet 110 of the main unit 1 flows into the air outlet component 2, and the wind is guided by the air outlet component 2 and then blown out. Figure 1 and Figure 2 It can be seen that the air outlet direction of the air outlet component 2 of the bathroom heater provided in the embodiment of the present disclosure is adjustable.

[0084] In this way, on the one hand, the blowing range of the bathroom heater can be expanded by periodically adjusting the air outlet direction of the air outlet component 2. On the other hand, when the bathroom heater is installed in place, if the blowing position of the bathroom heater is not ideal, the blowing position of the bathroom heater can be adjusted by adjusting the air outlet direction of the air outlet component 2, which is very easy to operate.

[0085] The following is an exemplary description of the implementation method of the adjustable air outlet direction of the air outlet component 2.

[0086] like Figure 3 and Figure 5-Figure 7 As shown, the air outlet component 2 includes a first air guide shell 21, an air guide cone 22 and a driving mechanism 23. The first air guide shell 21 has an air inlet 210, and the air inlet 210 is connected to the first air outlet 110 of the host 1. The outer diameter of the first end of the air guide cone 22 is smaller than the outer diameter of the second end of the air guide cone 22, and the first end of the air guide cone 22 extends toward the inside of the first air guide shell 21. The driving mechanism 23 is used to drive the air guide cone 22 to swing. In some examples, the first end of the air guide cone 22 extends into the inside of the first air guide shell 21.

[0087] The technical solution provided by the embodiment of the present disclosure is that when the air outlet component 2 is working, the wind blows out from the first air outlet 110 of the main unit 1 and then flows into the first air guide housing 21 through the first air inlet 210. After that, the wind flows into the air guide cone 22 under the guidance of the first air guide housing 21 and is blown out after being guided by the air guide cone 22. The driving mechanism 23 can drive the air guide cone 22 to swing, such as Figure 6 and Figure 7 As shown, during the swinging process of the wind guide cone 22, the wind guiding direction of the wind guide cone 22 will change, and the wind outlet direction of the wind outlet component 2 will also change. Thus, the wind outlet direction of the wind outlet component 2 is adjustable.

[0088] The air outlet direction of the bathroom heater in the related art is fixed and vertically downward, while the air outlet direction of the bathroom heater provided in the embodiment of the present disclosure is adjustable. Therefore, in some cases, the air outlet direction of the bathroom heater must be diagonally downward, which increases the length from the bathroom heater to the ground and increases the difficulty of the bathroom heater blowing air to the ground.

[0089] In order to make the bathroom heater easier to land, in some examples, such as Figure 5-Figure 7 As shown, the wind guide wall of the wind guide cone 22 is convex. In this way, the wind guide cone 22 can guide the wind outlet direction to be approximately consistent with the direction of the central axis of the wind guide cone 22, so that the wind outlet direction of the wind outlet component 2 is straighter and not too divergent, so that the wind blown out by the wind outlet component 2 is easier to land.

[0090] In some examples, such as Figure 5-Figure 7 As shown, the wind guide wall of the wind guide cone 22 includes a first wind guide segment 221. On any reference cross section where the central axis of the wind guide cone 22 is located, along the wind outlet direction, the angle between the tangent of the first wind guide segment 221 and the central axis of the wind guide cone 22 gradually decreases. That is, A1>A2>A3.

[0091] In this way, when the wind flows along the first wind guide section 221, the angle between the wind direction and the central axis of the wind guide cone 22 gradually decreases, so that the wind direction gradually deflects toward the direction indicated by the central axis of the wind guide cone 22, and the wind outlet direction of the wind outlet component 2 gradually becomes straight.

[0092] In some examples, such as Figure 6 As shown, on the reference cross section, the angle between the tangent line of the first air guiding section 221 and the central axis of the air guiding cone 22 is greater than 40° and less than 60°, that is, 60°>A1>A2>A3>40°.

[0093] In some examples, such as Figure 5-Figure 7 As shown, the wind guide wall of the wind guide cone 22 also includes a second wind guide segment 222, and the first wind guide segment 221 and the second wind guide segment 222 are arranged in sequence along the wind outlet direction. On the reference cross section, the angle between the tangent of the second wind guide segment 222 and the central axis of the wind guide cone 22 is greater than or equal to 0° and less than 10°. That is, the wind guide direction of the second wind guide segment 222 is approximately consistent with the direction indicated by the central axis of the wind guide cone 22, and the second wind guide segment 222 can adjust the wind outlet direction to be approximately consistent with the direction indicated by the central axis of the wind guide cone 22. Among them, the wind guide direction of the second wind guide segment 222 can be understood as the tangent direction of the second wind guide segment 222 on the reference cross section.

[0094] In some examples, such as Figure 5-Figure 7 As shown, on the reference cross section, the wind guiding wall of the second wind guiding section 222 is parallel to the central axis of the wind guiding cone 22. That is, the wind guiding direction of the second wind guiding section 222 is consistent with the direction indicated by the central axis of the wind guiding cone 22.

[0095] In other examples, on the reference cross section, along the air outlet direction, the angle between the tangent of the second air guiding section 222 and the central axis of the air guiding cone 22 gradually decreases. That is, the air guiding direction of the second air guiding section 222 gradually deflects toward the direction indicated by the central axis of the air guiding cone 22.

[0096] Generally speaking, when the first central axis X of the first air guide shell 21 and the second central axis Y of the air guide cone 22 coincide, the air outlet direction of the air outlet component 2 is vertically downward, and the air blown out by the bathroom heater is easier to land. As the swing angle of the air guide cone 22 increases, the air blown out by the bathroom heater will deflect horizontally, which makes it difficult for the air blown out by the bathroom heater to land. In some examples, during the swinging of the air guide cone 22, the angle α between the first central axis X and the second central axis Y does not exceed 10° to avoid the air outlet being too oblique and difficult to land.

[0097] Next, the air guide wall of the first air guide case 21 is exemplarily described.

[0098] In some examples, such as Figure 6 and Figure 7As shown, the air guiding wall of the first air guiding shell 21 has an arc surface, and the arc surface is concave in a direction away from the air guiding cone 22 .

[0099] In some examples, such as Figure 8 and Fig. 9 As shown, on the first reference section, along the air outlet direction, the first air guide shell 21 includes a third air guide segment 211 and a fourth air guide segment 212 in sequence. The inner diameter of the third air guide segment 211 increases in sequence along the air outlet direction, and along the air outlet direction, the angle between the tangent of the third air guide segment 211 and the central axis of the first air guide shell 21 gradually decreases, that is, B1>B2>B3. The air guide wall of the fourth air guide segment 212 is parallel to the central axis of the first air guide shell 21. Among them, the first reference section is parallel to the length direction of the air inlet 210, and the central axis of the first air guide shell 21 is located at the first reference section. Exemplarily, the air inlet 210 is rectangular.

[0100] The technical solution provided by the embodiment of the present disclosure is to gradually reduce the angle between the tangent of the third air guide section 211 and the central axis of the first air guide shell 21 along the wind outlet direction, so that the wind direction of the wind flowing along the third air guide section 211 gradually deflects toward the direction indicated by the central axis of the first air guide shell 21. And by setting the wind guide wall of the fourth air guide section 212 to be parallel to the central axis of the first air guide shell 21, the wind guide direction of the fourth air guide section 212 is consistent with the direction indicated by the central axis of the first air guide shell 21. Both of the above points can prevent the wind blown out of the first air guide shell 21 from being too divergent, thereby preventing the wind outlet of the air outlet component 2 from being too divergent, so that the wind blown out of the air outlet component 2 is easier to land.

[0101] In some examples, such as Fig.10 and Fig.11 As shown, on the second reference section, the inner diameter of the first air guide shell 21 increases successively along the air outlet direction, and the angle between the tangent of the air guide wall of the first air guide shell 21 and the central axis of the first air guide shell 21 gradually decreases. That is, C1>C2>C3. The second reference section is parallel to the width direction of the air inlet 210, and the central axis of the first air guide shell 21 is located at the second reference section.

[0102] In this way, when the wind flows along the first air guide shell 21, the wind direction gradually deviates toward the direction indicated by the central axis of the first air guide shell 21, thereby preventing the wind blown out of the first air guide shell 21 from being too divergent, and further preventing the wind outlet component 2 from being too divergent, making the wind blown out of the air outlet component 2 easier to fall to the ground.

[0103] In some examples, such as Fig.12As shown, when the central axes of the first air guide shell 21 and the air guide cone 22 coincide, the projection of the air guide cone 22 along the central axis of the first air guide shell 21 is partially located outside the air inlet 210. In this way, the outer diameter of the air guide cone 22 is large, and the air guide effect of the air guide cone 22 can be fully exerted.

[0104] In some examples, such as Figure 13-Figure 17 As shown, the air outlet component 2 further includes a second air guide shell 24, which is connected to the air guide cone 22. The first side of the second air guide shell 24 is connected to the first air guide shell 21, or the first side of the second air guide shell 24 extends into the interior of the first air guide shell 21. The second side of the second air guide shell 24 has a first opening 240, and an annular second air outlet 20 is formed between the inner wall of the first opening 240 and the second end of the air guide cone 22. The first side and the second side are two opposite sides of the second air guide shell 24.

[0105] The technical solution provided by the embodiment of the present disclosure, by providing the wind guide cone 22 and the second wind guide shell 24, enables the wind guide cone 22 to guide the middle airflow, and the second wind guide shell 24 to guide the peripheral airflow, thereby improving the guiding effect of the wind blown out by the first wind guide shell 21, making the wind blown out by the wind outlet component 2 straighter, and reducing wind loss. Therefore, the wind blown out by the wind outlet component 2 is easier to land.

[0106] In addition, the second air guide shell 24 swings along with the air guide cone 22, so that the shape of the second air outlet 20 does not change, which is convenient for setting the grille 25 at the second air outlet 20. Moreover, it is also convenient for the user to determine the air outlet direction of the bathroom heater by observing the position of the second air guide shell 24.

[0107] In some examples, such as Figure 13-Figure 15 As shown, the driving mechanism 23 is connected to the second air guide housing 24, and the driving mechanism 23 is used to drive the air guide cone 22 to swing through the second air guide housing 24. In this way, the driving mechanism 23 can be arranged outside the first air guide housing 21 and the second air guide housing 24, and the driving mechanism 23 will not block the airflow in the first air guide housing 21 and the second air guide housing 24, so that wind loss can be reduced.

[0108] In some examples, such as Fig.16 and Fig.17 As shown, along the air outlet direction, the inner diameter of the second air guide shell 24 gradually decreases. In this way, the second air guide shell 24 can gather the wind and reduce the divergence of the air blown by the air outlet component 2.

[0109] In some examples, such as Fig.18 and Fig.19As shown, on any reference cross section where the central axis of the second air guide shell 24 is located, along the air outlet direction, the second air guide shell 24 sequentially includes a fifth air guide segment 241 and a sixth air guide segment 242. The inner diameter of the fifth air guide segment 241 gradually decreases along the air outlet direction. The air guide wall of the sixth air guide segment 242 is parallel to the central axis of the first air guide shell 21.

[0110] The technical solution provided by the embodiment of the present disclosure can gather the wind blown out of the first wind guide shell 21 by setting the inner diameter of the fifth wind guide segment 241 to gradually decrease along the wind outlet direction. And by setting the wind guide wall of the sixth wind guide segment 242 to be parallel to the central axis of the first wind guide shell 21, the direction of the wind blown out along the sixth wind guide segment 242 can be approximately consistent with the direction indicated by the central axis of the wind guide cone 22, so that the wind direction of the wind blown out from the second air outlet 20 is straighter, and the wind blown out of the air outlet component 2 is easier to land.

[0111] In some examples, such as Fig.18 and Fig.19 As shown, along the air outlet direction, the angle between the tangent line of the fifth air guiding segment 241 and the central axis of the second air guiding shell 24 gradually increases, that is, D2>D1.

[0112] In some examples, such as Fig. 9 , Fig.11 and Fig. 20 As shown, the first air guide shell 21 has a second opening 213 on the side facing away from the air inlet 210, and the ratio of the inner diameter d2 of the first opening 240 to the inner diameter d1 of the second opening 213 is greater than 0.9 and less than 1.1. When the central axis of the first air guide shell 21 coincides with the central axis of the second air guide shell 24, the central axis of the first opening 240 coincides with the central axis of the second opening 213. In this way, the sizes of the first opening 240 and the second opening 213 are roughly the same. The wind blown out from the first opening 240 can be blown out from the second opening 213 more easily, reducing wind loss.

[0113] In some examples, such as Fig. 20 As shown, the width of the second air outlet 20 is b, and the diameter of the second end of the air guide cone 22 is d3, wherein b>0.25d3.

[0114] In some examples, such as Fig. 20 As shown, the length of the air inlet 210 is L, and the diameter of the second end of the air guide cone 22 is d3, where d3 < 0.75L. The length of the first air inlet 210 can also be understood as the length of the heater 13 (eg Fig.23 shown).

[0115] The technical solution provided by the embodiment of the present disclosure can prevent the diameter d3 of the second end of the air guide cone 22 from being too large, thereby reducing the width b of the second air outlet 20, resulting in increased air outlet damping, reduced air volume, and increased air leakage, by limiting the value of the diameter d3 of the second end of the air guide cone 22 or the width b of the second air outlet 20. Through the above arrangement, it is possible to ensure smooth air outlet and reduce air outlet damping and leakage.

[0116] The embodiment of the present disclosure does not limit the implementation method of the driving mechanism 23. In some examples, the driving mechanism 23 is used to drive the air guide cone 22 to rotate around a rotation axis.

[0117] In other examples, the driving mechanism 23 is used to drive the air guide cone 22 to rotate around two rotation axes, thereby achieving a larger blowing range. The following is an exemplary description of the implementation method of the driving mechanism 23 driving the air guide cone 22 to rotate around two rotation axes.

[0118] In some examples, such as Fig.13 and Fig.14 As shown, the driving mechanism 23 includes a first driving mechanism 231, a support ring 232, a first rotating shaft 233, a second driving mechanism 234 and a second rotating shaft 235. The support ring 232 is connected to the main unit 1 or the panel 3 for rotation around the first rotating shaft 233, and the second air guide housing 24 is located on the inner side of the support ring 232 and is connected to the support ring 232 for rotation around the second rotating shaft 235. The first driving mechanism 231 is provided on the main unit 1 or the panel 3, and the first driving mechanism 231 is used to drive the support ring 232, the second air guide housing 24 and the air guide cone 22 to swing around the first rotating shaft 233. The second driving mechanism 234 is provided on the support ring 232, and the second driving mechanism 234 is used to drive the second air guide housing 24 and the air guide cone 22 to swing around the second rotating shaft 235.

[0119] The first rotating shaft 233 and the second rotating shaft 235 intersect, such as being perpendicular. In some examples, the first rotating shaft 233 and the second rotating shaft 235 are both perpendicular to the central axis of the second air guide housing 24 .

[0120] In the technical solution provided by the embodiment of the present disclosure, the first driving mechanism 231 can drive the support ring 232, the second air guide shell 24 and the air guide cone 22 to swing together relative to the host 1 or the panel 3 around the first rotation axis 233. The second driving mechanism 234 can drive the second air guide shell 24 and the air guide cone 22 to swing together relative to the support ring 232 around the second rotation axis 235. Thus, the second air guide shell 24 and the air guide cone 22 are swung around two rotation axes, and a larger adjustment range of the air outlet direction of the air outlet component 2 can be achieved.

[0121] In some examples, such as Fig.13 and Fig.14As shown, a base 311 is provided on the panel 3, and the support ring 232 is rotatably connected to the base 311 via a first rotating shaft 233. The second air guide housing 24 is rotatably connected to the support ring 232 via a second rotating shaft 235.

[0122] In some examples, such as Fig.13 and Fig.14 As shown, the first driving mechanism 231 includes a first motor 2311, a first gear 2312 and a second gear 2313. The first motor 2311 is mounted on the panel 3. The first gear 2312 is sleeved on the output shaft of the first motor 2311. The second gear 2313 is fixed on the supporting ring 232, and the first gear 2312 and the second gear 2313 are meshed.

[0123] In this way, the first motor 2311 can drive the support ring 232 , the second air guide shell 24 and the air guide cone 22 to swing around the first rotating shaft 233 through the first gear 2312 and the second gear 2313 .

[0124] In some examples, such as Fig.13 and Fig.14 As shown, the second driving mechanism 234 includes a second motor 2341, a third gear 2342 and a fourth gear 2343. The second motor 2341 is mounted on the support ring 232. The third gear 2342 is sleeved on the output shaft of the second motor 2341. The fourth gear 2333 is fixed on the second air guide housing 24, and the third gear 2342 is meshed with the fourth gear 2333.

[0125] In this way, the second motor 2341 can drive the second air guide shell 24 and the air guide cone 22 to swing around the second rotating shaft 235 through the third gear 2342 and the fourth gear 2333 .

[0126] In addition to providing the second air guide housing 24 that moves with the air guide cone 22, in other examples, such as Fig.21 and Fig. 22 As shown, the first end and the second end of the air guide cone 22 are both extended into the interior of the first air guide shell 21, and the top of the first air guide shell 21 has a third opening 2150, and an annular second air outlet 20 is formed between the inner wall of the third opening 2150 and the second end of the air guide cone 22. The driving mechanism 23 is connected to the air guide cone 22.

[0127] In some examples, such as Fig.21 and Fig. 22As shown, the first air guide shell 21 includes an air expansion section 214 and an air shielding section 215. The air expansion section 214 has an air inlet 210, and the air shielding section 215 has a third opening 2150. The inner diameter of the air shielding section 215 gradually decreases along the air outlet direction. The first end of the air guide cone 22 is located at the air expansion section 214, and the second end of the air guide cone 22 is located at the air shielding section 215. The air shielding section 215 can block the peripheral wind and gather the peripheral wind to prevent the air blown by the air outlet component 2 from being too divergent.

[0128] Below, the main unit 1 and panel 3 of the bathroom heater are exemplarily described.

[0129] In some examples, such as Fig.23 As shown, the host 1 includes a housing 11, a wind wheel 12 and a heater 13. The wind wheel 12 is located inside the housing 11. The housing 11 has a first air outlet 110, and the heater 13 is located in the first air outlet 110. Exemplarily, there are two wind wheels 12, which are arranged on both sides of the first air outlet 110.

[0130] In some examples, such as Figure 4 As shown, the panel 3 includes an inner panel 31 and an outer panel 32, and there is a gap for air intake between the inner panel 31 and the outer panel 32. The inner panel 31 and the outer panel 32 are provided with a avoidance opening 30, and the air outlet component 2 is installed in the avoidance opening 30, and the air guide cone 22 of the air outlet component 2 can swing in the avoidance opening 30.

[0131] like Figure 4 As shown, when the bathroom heater is working, the wind wheel 12 rotates, and the wind flows into the interior of the housing 11 from the gap between the inner panel 31 and the outer panel 32. After being heated by the heater 13, the wind is blown out from the first air outlet 110 of the housing 11, and then flows through the first guide shell 21 and the wind guide cone 22 in sequence, and is blown out from the air outlet component 2. In addition, when the driving mechanism 23 drives the wind guide cone 22 to swing, the air outlet direction of the bathroom heater changes.

[0132] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
