DETAILED DESCRIPTION

[0064] 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.

[0065] 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.

[0066] A bathroom heater is a device that is installed in the bathroom and blows warm air to provide heating when the user is bathing.

[0067] The air outlet of the bathroom heater in the related art is fixed, which means that after the bathroom heater is installed, 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. In addition, the blowing range of the bathroom heater in the related art is also relatively small.

[0068] 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.

[0069] In this way, on the one 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 outlet direction of the air outlet component 2. On the other hand, by periodically adjusting the outlet direction of the air outlet component 2, the blowing range of the bathroom heater can also be expanded.

[0070] The following is an exemplary description of the implementation method of the adjustable air outlet direction of the air outlet component 2.

[0071] like Figure 3 and Figure 5 As shown, the air outlet component 2 includes a first air guide housing 21, a second air guide housing 22 and a driving mechanism 23. The first air guide housing 21 has an air inlet 210, and the air inlet 210 is connected to the first air outlet 110 of the host 1. The first side of the second air guide housing 22 surrounds the first air guide housing 21 (as shown in FIG. Figure 5 Alternatively, the first side of the second air guide housing 22 extends into the interior of the first air guide housing 21 (as shown in Figure 8 The second side of the second air guide housing 22 has an opening 220, wherein the first side and the second side are two opposite sides of the second air guide housing 22. The driving mechanism 23 is used to drive the second air guide housing 22 to swing.

[0072] According to the technical solution provided by the embodiment of the present disclosure, when the air outlet component 2 is working, after the wind is blown out from the first air outlet 110 of the main unit 1, it first flows into the first air guide shell 21 through the air inlet 210. Afterwards, under the guidance of the first air guide shell 21, the wind flows into the interior of the second air guide shell 22 and blows out from the opening 220 of the second air guide shell 22. The driving mechanism 23 can drive the second air guide shell 22 to swing, and during the swinging process of the second air guide shell 22, the direction of the opening 220 will change, and the air outlet direction of the air outlet component 2 will also change. Thus, the air outlet direction of the air outlet component 2 is adjustable.

[0073] In some examples, such as Figure 5 and Figure 6 As shown, there is a certain gap between the first air guide shell 21 and the second air guide shell 22, so as to avoid interference between the second air guide shell 22 and the first air guide shell 21 during the swinging process. However, the existence of the above gap makes the wind leak from the gap between the first air guide shell 21 and the second air guide shell 22 during the process of wind flowing from the first air guide shell 21 to the second air guide shell 22.

[0074] In order to reduce the amount of leaked air, in some examples, such as Figure 6-Figure 8As shown, on any cross section where the central axis of the first air guide shell 21 is located, the straight line passing through the highest point and the lowest point of the first side of the second air guide shell 22 is the first straight line A. During the swinging process of the second air guide shell 22, that is, no matter where the second air guide shell 22 swings to, the end surface of the first air guide shell 21 away from the air inlet 210 is always located on the side of the first straight line A facing the opening 220. In this way, the wind flows from the first air guide shell 21 to the second air guide shell 22 more smoothly, and the amount of wind leaking from the gap between the first air guide shell 21 and the second air guide shell 22 is small.

[0075] In some examples, such as Figure 5-Figure 7 As shown, the air outlet component 2 further includes a wind shield ring 25, a portion of the wind shield ring 25 surrounds the second air guide shell 22, and / or another portion of the wind shield ring 25 surrounds the first air guide shell 21. Fig.11 As shown, the wind shielding ring 25 can block the wind leaking from the gap between the first wind guide shell 21 and the second wind guide shell 22, thereby reducing the amount of air leakage from the air outlet component 2. The gap includes gaps in the horizontal and vertical directions.

[0076] The embodiment of the present disclosure does not limit the installation method of the wind shielding ring 25. In some examples, the wind shielding ring 25 is connected to the first wind guide shell 21 (e.g., fixedly connected), and protrudes relative to the end surface of the first wind guide shell 21 away from the air inlet 210. In this way, when the central axis of the second wind guide shell 22 coincides with the central axis of the first wind guide shell 21, the wind shielding ring 25 surrounds the first wind guide shell 21 and the second wind guide shell 22.

[0077] In other examples, the wind shield ring 25 is connected to the second wind guide shell 22 and protrudes relative to the first side of the second wind guide shell 22. In this way, when the central axes of the first wind guide shell 21, the second wind guide shell 22 and the wind shield ring 25 coincide, the wind shield ring 25 surrounds the first wind guide shell 21 and the second wind guide shell 22. In some examples, the wind shield ring 25 is fixedly connected to the second wind guide shell 22 and is coaxial, so that the wind shield ring 25 swings with the second wind guide shell 22.

[0078] In other examples, the wind shield ring 25 is an integral connection piece with the second air guide shell 22, and protrudes relative to the first lateral air inlet 210 of the second air guide shell 22. In other examples, the wind shield ring 25 is an integral connection piece with the first air guide shell 21, and protrudes toward the second air guide shell 22 relative to the first air guide shell 21. Both methods are conducive to assembly and manufacturing, and the wind shield ring 25 can partially block the gap between the first air guide shell 21 and the second air guide shell 22, block the leaked wind, and thus reduce the air leakage of the air outlet component 2.

[0079] Wherein, the gap includes gaps in the horizontal and vertical directions. When the wind shield ring 25 and the second air guide shell 22 are connected as an integral part or the wind shield ring 25 and the first air guide shell 21 are connected as an integral part, the second air guide shell 22 and / or the air guide body 24 can be rotated by, for example, driving the second air guide shell 22 and / or the air guide body 24 inside or outside the second air guide shell 22, that is, the driving mechanism 23 can be arranged in a place other than the second air guide shell 22, such as on the first air guide shell 21 or the host for relatively fixed installation.

[0080] In other examples, the wind shielding ring 25 is rotatably connected to the second wind guide shell 22. The specific implementation of the rotatable connection will be described below.

[0081] 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 second air guide shell 22 to rotate around a rotation axis.

[0082] In other examples, the driving mechanism 23 is used to drive the second air guide housing 22 to rotate around two rotation axes, thereby achieving a larger blowing range. Below, the implementation method of the driving mechanism 23 driving the second air guide housing 22 to rotate around two rotation axes is exemplarily described.

[0083] In some examples, such as Figure 3 , Fig. 9 and Fig.10 As shown, the driving mechanism 23 includes a first driving mechanism 231 and a second driving mechanism 232. The wind shield ring 25 is connected to the main unit 1 or the panel 3 for rotation around the first rotation axis, and the second wind guide shell 22 is located on the inner side of the wind shield ring 25 and is connected to the wind shield ring 25 for rotation around the second rotation axis. 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 wind shield ring 25 and the second wind guide shell 22 to swing around the first rotation axis. The second driving mechanism 232 is provided on the wind shield ring 25, and the second driving mechanism 232 is used to drive the second wind guide shell 22 to swing around the second rotation axis.

[0084] The first rotation axis and the second rotation axis intersect, such as being perpendicular. In some examples, the first rotation axis and the second rotation axis are both perpendicular to the central axis of the second air guide shell 22 .

[0085] In the technical solution provided by the embodiment of the present disclosure, the first driving mechanism 231 can drive the wind shielding ring 25 and the second wind guide housing 22 to swing together relative to the main unit 1 or the panel 3 around the first rotation axis. The second driving mechanism 232 can drive the second wind guide housing 22 to swing relative to the wind shielding ring 25 around the second rotation axis. Thus, the second wind guide housing 22 is swung around two rotation axes, and a larger adjustment range of the air outlet direction of the air outlet component 2 can be achieved.

[0086] In some examples, such as Fig. 9 and Fig.10 As shown, a base 311 is provided on the panel 3, and the wind shielding ring 25 is rotatably connected to the base 311 via a first rotating shaft 27. The axis of the first rotating shaft 27 is the first rotating axis. The second wind guide shell 22 is rotatably connected to the wind shielding ring 25 via a second rotating shaft 28. The axis of the second rotating shaft 28 is the second rotating axis.

[0087] In some examples, such as Fig. 9 and Fig.10 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 wind shield ring 25, and the rotation axis of the second gear 2313 is the first rotation axis. The first gear 2312 is meshed with the second gear 2313.

[0088] In this way, the first motor 2311 can drive the wind shield ring 25 and the second wind guide shell 22 to swing around the first rotation axis through the first gear 2312 and the second gear 2313.

[0089] In some examples, such as Fig. 9 and Fig.10 As shown, the second driving mechanism 232 includes a second motor 2321, a third gear 2322 and a fourth gear 2323. The second motor 2321 is mounted on the wind shielding ring 25. The third gear 2322 is sleeved on the output shaft of the second motor 2321. The fourth gear 2323 is fixed on the second wind guide housing 22, and the rotation axis of the fourth gear 2323 is the second rotation axis. The third gear 2322 is meshed with the fourth gear 2323.

[0090] In this way, the second motor 2321 can drive the second air guide shell 22 to swing around the second rotation axis through the third gear 2322 and the fourth gear 2323.

[0091] In some examples, such as Fig.11 As shown, when the central axes of the first air guide shell 21, the second air guide shell 22 and the wind shielding ring 25 coincide, the wind shielding ring 25 protrudes relative to the first side of the second air guide shell 22, a portion of the wind shielding ring 25 surrounds the second air guide shell 22, and another portion of the wind shielding ring 25 surrounds the first air guide shell 21. Fig.11 As shown, the wind shielding ring 25 can block the wind leaking from the gap between the first wind guiding shell 21 and the second wind guiding shell 22, thereby reducing the air leakage of the air outlet component 2.

[0092] In addition, in order to ensure that the wind shielding ring 25 can block the leaked wind when the second wind guide shell 22 swings to any position, in some examples, such as Fig.15As shown, during the swinging process of the second air guide housing 22 around the first rotation axis and around the second rotation axis, or when the second air guide housing 22 rotates to the limit angle:

[0093] The side of the wind shielding ring 25 close to the air inlet 210 of the first air guide shell 21 (where the annular convex strip 251 is located) is lower than the end surface of the first air guide shell 21 away from the air inlet 210;

[0094] And / or, one side of the wind shield ring 25 close to the air inlet 210 of the first air guide shell 21 (where the annular protrusion 251 is located) is lower than the end surface of the first air guide shell 21 away from the air inlet 210 and the other side of the wind shield ring 25 is higher than the side of the second air guide shell 22 close to the air inlet 210.

[0095] In this way, the leaked wind will come into contact with the wind shielding ring 25 and be blocked by the wind shielding ring 25.

[0096] To further improve the wind shielding effect of the wind shielding ring 25, in some examples, such as Figure 6-Figure 7 and Figure 11-Figure 12 As shown, the minimum inner diameter D2 of the portion of the wind shielding ring 25 surrounding the first wind guide shell 21 is smaller than the inner diameter D1 of the first side of the second wind guide shell 22. Alternatively, the portion of the wind shielding ring 25 surrounding the first wind guide shell 21 protrudes toward the inner side of the first wind guide shell 21 relative to the inner wall of the first side of the second wind guide shell 22.

[0097] In some examples, such as Figure 6-Figure 7 and Figure 11-Figure 12 As shown, the difference between the inner diameter D1 of the first side of the second air guide shell 22 and the minimum inner diameter D2 of the portion of the wind shield ring 25 surrounding the first air guide shell 21 is greater than 6 mm and less than 16 mm. That is, D1-D2 is greater than 6 mm and less than 16 mm. Alternatively, it can be understood that 2d1 is greater than 6 mm and less than 16 mm, and d1 is greater than 3 mm and less than 8 mm.

[0098] To further improve the wind shielding effect of the wind shielding ring 25, in some examples, such as Figure 11-13 As shown, the wind shielding ring 25 has an annular protrusion 251 protruding toward the first wind guide shell 21 , and the annular protrusion 251 surrounds the first wind guide shell 21 .

[0099] The provision of the annular ridge 251 reduces the value of the minimum inner diameter D2 of the portion of the wind shield ring 25 surrounding the first wind guide shell 21, thereby improving the wind shielding effect of the wind shield ring 25. It should be noted that, for the solution with the annular ridge 251, D2 may also be not less than D1, for example, D2 is greater than or equal to D1.

[0100] In other examples, such as Fig.14As shown, the wind shielding ring 25 has a tapered portion 252 , which surrounds the first wind guide shell 21 , and the inner diameter of the tapered portion 252 gradually decreases along the direction pointing to the air inlet 210 of the first wind guide shell 21 .

[0101] The setting of the tapered portion 252 reduces the value of the minimum inner diameter D2 of the portion of the wind shielding ring 25 surrounding the first wind guide shell 21, thereby improving the wind shielding effect of the wind shielding ring 25. It should be supplemented that, for the solution with the tapered portion 252, D2 may also be not less than D1, for example, D2 is greater than or equal to D1.

[0102] In addition, in order to reduce the amount of wind leaking from the gap between the first air guide shell 21 and the second air guide shell 22, in some examples, such as Figure 6 As shown, the central axis of the first air guide shell 21 is the first central axis B, and the central axis of the second air guide shell 22 is the second central axis C. When the angle between the first central axis B and the second central axis C is the largest, the minimum distance d2 between the highest point on the first side of the second air guide shell 22 and the first air guide shell 21 is greater than 12 mm. The highest point is the point on the first side of the second air guide shell 22 that is farthest from the air inlet 210 of the first air guide shell 21.

[0103] Generally speaking, when the first central axis B of the first air guide shell 21 and the second central axis C of the second air guide shell 22 coincide, the opening 220 of the second air guide shell 22 is vertically downward, and the wind blown out by the bathroom heater is also vertically downward, and the wind blown out by the bathroom heater is more likely to fall to the ground. As the swing angle of the second air guide shell 22 increases, the wind blown out by the bathroom heater will deflect horizontally, which makes it difficult for the wind blown out by the bathroom heater to fall to the ground, affecting the user's body feeling. In some examples, such as Figure 6 As shown, during the swinging process of the second air guide shell 22 , the angle α between the first central axis B and the second central axis C does not exceed 10° to prevent the second air guide shell 22 from swinging too much.

[0104] In order to improve the wind guiding effect, in some examples, such as Figure 5 and Figure 6 As shown, the air outlet component 2 further includes an air guide body 24, which is located inside the second air guide shell 22 and connected to the second air guide shell 22. The first end of the air guide body 24 extends toward the inside of the first air guide shell 21, and a second annular air outlet 20 is formed between the second end of the air guide body 24 and the inner wall of the opening 220 of the second air guide shell 22.

[0105] In some examples, the first end of the air guide body 24 extends into the interior of the first air guide shell 21 .

[0106] The technical solution provided by the embodiment of the present disclosure is to set an air guide body 24 inside the second air guide shell 22, so that the second air guide shell 22 can guide the peripheral airflow, and the air guide body 24 can guide the middle airflow, thereby improving the guiding effect of the wind blown out by the first air guide shell 21 and reducing wind loss.

[0107] In some examples, such as Figure 5 and Figure 6 As shown, the air guide body 24 is an air guide cone, the first end of the air guide body 24 is a small-diameter end, and the second end of the air guide body 24 is a large-diameter end.

[0108] In some examples, such as Figure 6 As shown, the width of the second air outlet 20 is b, and the diameter of the large diameter end of the air guide 24 is D3, wherein b>0.25D3.

[0109] In some examples, such as Figure 6 As shown, the length of the air inlet 210 is L, and the diameter of the large diameter end of the air guide 24 is D3, where D3 < 0.75L. The length of the air inlet 210 can also be understood as the length of the heater 13 (such as Fig.17 shown).

[0110] The technical solution provided by the embodiment of the present disclosure can prevent the diameter D3 of the large diameter end of the air guide 24 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 large diameter end of the air guide 24 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.

[0111] In some examples, such as Figure 5 and Figure 6 As shown, the air outlet component 2 includes a grille 26 , which is annular and disposed in the annular second air outlet 20 .

[0112] It should be noted that in other examples, such as Fig.16 As shown, the air outlet component 2 may also not include the air guide member 4 , and the opening 220 of the second air guide shell 22 is the second air outlet 20 .

[0113] Below, the main unit 1 and panel 3 of the bathroom heater are exemplarily described.

[0114] In some examples, such as Fig.17 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.

[0115] 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 second air guide shell 22 of the air outlet component 2 is installed in the avoidance opening 30 and can swing in the avoidance opening 30.

[0116] 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 second air guide shell 22 in sequence, and blows out from the opening 220 of the second air guide shell 22. In addition, when the driving mechanism 23 drives the second air guide shell 22 to swing, the direction of the opening 220 of the second air guide shell 22 changes, so that the air outlet direction of the bathroom heater changes.

[0117] 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.
