[0002] With the improvement of modern living standards, people's requirements for the comfort and health of the living environment are increasing, especially in the private and high-humidity environment of the bathroom, the demand for heating, exhaust and blowing functions is more urgent. As an indispensable electrical device in the bathroom, the main function of the bathroom heater is to increase the temperature of the bathroom by heating and blowing, and to keep the air in the bathroom fresh by exhausting. Most of the existing bathroom heaters adopt a single air outlet design, which leads to a limited air supply area, and it is easy to have a phenomenon that the temperature of the area close to the air outlet is too high, while the temperature of the area far from the air outlet is relatively low. This problem of uneven temperature distribution affects the overall comfort of the bathroom.

[0017] From the above description of the various embodiments of the present invention, it can be seen that, compared with the prior art, the various embodiments of the present invention have the following advantages:

[0018] Beneficial effects:

[0019] In the first technical solution and related embodiments, the air duct outlet control structure realizes effective control of the air outlet area of ​​the first air duct by introducing the design of the shielding component and at least one rotating leaf thereof. The user can flexibly adjust the shielding area of ​​the first air duct by controlling the rotation of the rotating leaf as needed, thereby controlling the air outlet volume of the first air duct.

[0020] In the second technical solution and related embodiments, which is one of the embodiments, a fixed page is introduced into the shielding component and combined with the rotating page. The fixed page is an immovable part and serves as the basic frame of the shielding component, while the rotating page moves flexibly within this frame. By changing the relative position between the rotating page and the fixed page, dynamic adjustment of the shielding area is achieved.

[0021] In the third technical solution and related embodiments, which is one of the embodiments, at least two rotating leaves are used as components of the shielding assembly, and the rotating leaves can rotate relative to each other to adjust the shielding area. By changing the relative positions of the rotating leaves, the shielding area can be adjusted, the airflow dead angle is reduced, and the air supply effect is optimized.

[0022] In the fourth technical solution and related embodiments, at least one driving unit consisting of an active rotating page and a passive rotating page is introduced, and the rotation of the active rotating page drives the passive rotating page to rotate synchronously, thereby realizing the linkage control of the shielding component. This design simplifies the control logic, reduces the number of components that need to be controlled separately, and reduces the complexity and cost of the system.

[0023] In the fifth technical solution and related embodiments, a cascaded driving unit design is introduced, that is, the passive rotating page of the upper driving unit is used as the active rotating page of the lower driving unit, so that a multi-level linkage effect can be formed between the driving units. When the uppermost active rotating page is controlled, its rotation will be transmitted step by step through the driving units at each level, and finally drive all the rotating pages to rotate synchronously, thereby realizing the control of the entire shielding assembly.

[0024] In the sixth technical solution and related embodiments, the cooperation design of the pushing portion and the abutting portion ensures that the active rotating page can stably and reliably push the passive rotating page to rotate during the rotation process. This mechanical transmission method is simple and direct, reducing the difficulty and cost of design and manufacturing.

[0025] In the seventh technical solution and related embodiments, when the active rotating page in the uppermost driving unit rotates in the opposite direction to the first rotation direction, the reverse thrust portion thereon will push the passive rotating page in the adjacent secondary driving unit to move in the opposite direction. This pushing action will be transmitted in sequence, and the passive rotating pages in the multi-layer driving units will gradually overlap in the same way. In this process, the rotating pages that may have originally blocked the air outlet are pushed back one by one until all the rotating pages are completely stacked along the air outlet direction and no longer block the air outlet path. At this time, the air outlet is in a fully open or maximally open state to achieve the best air supply effect.

[0026] In the eighth technical solution and related embodiments, the air outlet device realizes dual regulation of the airflow through the design of the first air duct and the second air duct working independently or in collaboration. The first air duct is located in the center, providing a direct and concentrated air supply effect. The air outlet control structure of the first air duct flexibly adjusts the air volume to meet the wind speed requirements of different users. The second air duct surrounds the first air duct layout, and its control structure uses a rotating part to drive the swing wind blade to rotate, and can adjust the air outlet angle arbitrarily within a 360° range, thereby enhancing the diversity and coverage of the air supply. In this air outlet device, the first air duct surrounded by the second air duct forms two independent air supply channels inside and outside. In addition, the independent control systems of the first air duct and the second air duct not only retain the ability to supply air from both the inner and outer air outlets at the same time, but also allow users to selectively open or close the air supply function of any air duct according to actual needs, thereby meeting the air supply requirements in different scenarios and enhancing the user's experience.

[0027] In the ninth technical solution and related embodiments, the air outlet device further improves the control accuracy and stability of the air outlet angle through the meshing transmission mechanism between the rotating wheel and the driven wheel. The rotation of the rotating member on the bottom shell is transmitted to the driven wheel on the swing leaf through the rotating wheel, driving the swing leaf to rotate smoothly around its rotation axis, realizing continuous and smooth adjustment of the air outlet angle, thereby realizing the control of the air outlet angle.

[0028] In the tenth technical solution and related embodiments, the design of the olive-shaped grille helps to optimize the distribution of airflow. Compared with the traditional straight or square grille, the olive-shaped grille can more effectively guide the airflow direction, reduce the turbulence and eddy flow of the airflow at the air outlet, and reduce wind resistance and noise level.

[0029] In the eleventh technical solution and related embodiments, the bathroom heater connects the fan and the air outlet device through the main air duct to form an air flow transmission system, realizing a single-duct dual-outlet air supply system. The main air duct is directly opposite to the first air duct, ensuring that high-speed, concentrated airflow can directly enter the first air duct and achieve a direct blowing effect. At the same time, the second air duct surrounds the first air duct layout and realizes multi-angle air supply through the swinging wind blades, enhancing the diversity and flexibility of air supply.

[0030] In the twelfth technical solution and related embodiments, the duct arc surface gradient design reduces wind resistance and improves the flow efficiency of the airflow. The smooth transition of the duct arc surface reduces the energy loss and turbulence of the airflow during turning and acceleration, allowing the airflow to pass through the duct more smoothly and reach a predetermined air outlet speed and direction.

[0057] Embodiment 1

[0058] like Figures 7 to 10 As shown, a duct outlet control structure is used to control the outlet area of ​​the first duct 9, and the first duct 9 is connected to the first air outlet 30. The duct outlet control structure includes a shielding component and a first motor 21. The shielding component includes at least one rotating page 18, and the rotating page 18 rotates to change the shielding area of ​​the first duct 9 by the shielding component. The first motor 21 controls the rotation of the rotating page 18 to change the shielding area of ​​the first duct 9. In this embodiment, the duct outlet control structure realizes effective control of the outlet area of ​​the first duct 9 by introducing the design of the shielding component and at least one rotating page 18 thereof. The user can flexibly adjust the shielding area of ​​the first duct 9 by controlling the rotation of the rotating page 18 as needed, thereby controlling the air volume of the first duct 9. Specifically, the shape of the rotating page 18 is fan-shaped, and a plurality of rotating pages 18 are overlapped and layered to form a shielding component along the air outlet direction. The size of the first air outlet 30 is controlled by the contraction and folding method of the rotating page 18, and the rotating page 18 can be fully folded, half folded, and other angles.

[0059] There are at least two rotating pages 18 in the shielding assembly, and each rotating page 18 is adapted to rotate relative to at least one other rotating page 18 to change the shielding area of ​​the shielding assembly. At least two rotating pages 18 are used as components of the shielding assembly, and the rotating pages 18 can rotate relative to each other to adjust the shielding area. By changing the relative positions of the rotating pages 18, the shielding area can be adjusted, the airflow dead angle can be reduced, and the air supply effect can be optimized.

[0060] At least one group of rotating pages 18 constitutes a driving unit, and the driving unit includes an active rotating page 19 and a passive rotating page 20. When the active rotating page 19 rotates, the passive rotating page 20 is driven to rotate. At least one group of driving units consisting of an active rotating page 19 and a passive rotating page 20 is introduced, and the passive rotating page 20 is driven to rotate synchronously by the rotation of the active rotating page 19, thereby realizing the linkage control of the shielding component. This design simplifies the control logic, reduces the number of components that need to be controlled separately, and reduces the complexity and cost of the system.

[0061] When there are more than two driving units, the passive rotating page 20 of the upper driving unit serves as the active rotating page 19 of the lower driving unit. By introducing a cascade driving unit design, that is, the passive rotating page 20 of the upper driving unit serves as the active rotating page 19 of the lower driving unit, a multi-level linkage effect can be formed between the driving units. When the uppermost active rotating page 19 is controlled, its rotation will be transmitted step by step through the driving units at each level, and finally drive all the rotating pages 18 to rotate synchronously, thereby realizing the control of the entire shielding assembly.

[0062] Automatically rotate page 19, such as Figure 7 and Figure 8 As shown, it adopts the shape of a fan-shaped blade, and a semicircular shaft hole 23 is provided in the center thereof, which is used to be connected to the motor shaft 22 so as to rotate with the rotation of the motor shaft 22. On the side of the active rotating leaf 19 facing the passive rotating leaf 20, a push portion 25 is designed at one end, which is specifically in the form of a convex point, and is used to push the corresponding part of the passive rotating leaf 20 during the rotation process; the other end is designed as a reverse thrust portion 27, which is a folded edge perpendicular to the fan-shaped plane, and is used to push the passive rotating leaf 20 to move in the reverse direction when the motor rotates in the reverse direction.

[0063] Passive rotation page 20, such as Figure 7As shown, it is also fan-shaped, but the middle shaft hole is circular so that it can be installed on the motor shaft 22 instead of rotating directly with the motor. Each passive rotating leaf 20 is provided with two abutment portions 26, both of which are in the shape of convex points. The positions of the two abutment portions 26 are: one is close to the corresponding position of the push portion 25 of the upper active rotating leaf 19, so as to receive the thrust from the active rotating leaf 19; at the same time, the passive rotating leaf 20 also serves as the active rotating leaf 19 of the next level driving unit, and the other abutment portion 26 is close to the corresponding position of the abutment portion 26 of the lower passive rotating leaf 20, so as to transmit the rotational force at the next level.

[0064] The first motor 21 is provided with a motor shaft 22, and a notch is designed on the motor shaft 22 to correspond to the semicircular shaft hole 23 of the active rotating page 19, so that the motor shaft 22 is connected to the active rotating page 19 to prevent rotation. During installation, multiple rotating pages 18 (including the active rotating page 19 and the passive rotating page 20) are overlapped and installed on the motor shaft 22 through their intermediate shaft holes. The semicircular shaft hole 23 of the active rotating page 19 fits with the notch of the motor shaft 22, ensuring that when the first motor 21 rotates, the active rotating page 19 can rotate synchronously therewith. The passive rotating page 20 has a circular shaft hole 24 in the middle. Although it is installed on the motor shaft 22, it does not directly rotate with the motor, but moves through the thrust or reverse thrust of the upper rotating page 18.

[0065] When the active rotating page 19 rotates along the first rotation direction until the pushing portion 25 abuts against the abutting portion 26, the passive rotating page 20 is driven to rotate. The matching design of the pushing portion 25 and the abutting portion 26 ensures that the active rotating page 19 can stably and reliably push the passive rotating page 20 to rotate during the rotation process. This mechanical transmission method is simple and direct, reducing the difficulty and cost of design and manufacturing.

[0066] The active rotating page 19 in the uppermost driving unit is provided with a reverse thrust portion 27, which is suitable for pushing other rotating pages 18 to rotate when rotating away from the first rotation direction until all rotating pages 18 are stacked along the air outlet direction. When the active rotating page 19 in the uppermost driving unit rotates in the opposite direction of the first rotation direction, the reverse thrust portion 27 thereon will push the passive rotating page 20 in the adjacent secondary driving unit to move in the opposite direction. This pushing action will be transmitted in sequence, and the passive rotating pages 20 in the multi-layer driving units will gradually overlap in the same way. In this process, the rotating pages 18 that may have originally blocked the first air outlet 30 are pushed back one by one until all rotating pages 18 are completely stacked along the air outlet direction and no longer block the air outlet path. At this time, the first air outlet 30 is in a fully open or maximally open state to achieve the best air supply effect.

[0067] The specific implementation is as follows:

[0068] When the first motor 21 is started and rotates forward, it drives the active rotating leaf 19 installed on the first layer to rotate. The push portion 25 equipped on the active rotating leaf 19 will then abut against the abutment portion 26 of the passive rotating leaf 20 on the second layer, and this abutment causes the passive rotating leaf 20 to start rotating. Subsequently, the abutment portion 26 of the passive rotating leaf 20 on the second layer continues to transmit this rotational motion in a similar manner, activating and driving the passive rotating leaf 20 of the next level to rotate in turn. When the first motor 21 completes a full rotation of 360°, all the rotating leaves 18 will be fully unfolded, reaching the state as shown in the figure. Fig. 9 In the state shown, the internal air outlet is in a closed state due to the obstruction of the rotating leaf 18.

[0069] On the contrary, when the first motor 21 rotates in the reverse direction, the reverse thrust portion 27 on the active rotating leaf 19 contacts and pushes the side of the second layer of passive rotating leaf 20, and this reverse thrust causes the passive rotating leaf 20 to start to move in the reverse direction. Subsequently, this reverse motion is sequentially transmitted through the interaction between the passive rotating leaves 20 at each level, so that all the passive rotating leaves 20 gradually overlap. When all the rotating leaves 18 are rearranged and overlapped in this way, as shown in FIG. Fig.10 As shown, the internal air outlet is thus opened, allowing air to circulate.

[0070] Embodiment 2

[0071] Different from the first embodiment, the shielding assembly also includes a fixed page, and the rotating page 18 rotates relative to the fixed page to change the shielding area of ​​the shielding assembly. In this embodiment, a fixed page is introduced into the shielding assembly and combined with the rotating page 18. The fixed page, as an immovable part, is the basic frame of the shielding assembly. The fixed page is usually installed at the edge, corner or specific position of the shielding assembly to enhance the overall structural stability of the shielding assembly. The rotating page 18 moves flexibly within this frame, and the dynamic adjustment of the shielding area is achieved by changing the relative position between the rotating page 18 and the fixed page. The fixed page itself also has a certain shielding area, and together with the rotating page 18, it constitutes the overall shielding range of the shielding assembly.

[0072] Embodiment 3

[0073] An air outlet device, such as Figures 4 to 6As shown, it includes a bottom shell 2, a rotating member 11, a plurality of swinging leaves 14, an air outlet cover 10 and the above-mentioned air duct outlet control structure. The bottom shell 2 is provided with a first air duct 9 and a second air duct 8 both of which discharge air in a first direction, respectively connected to a first air outlet 30 and a second air outlet 29, the second air duct 8 surrounds the first air duct 9, and the air duct outlet control structure is installed on the first air duct 9; the rotating member 11 is arranged around the second air duct 8 and meshes with the swinging leaves 14, and the rotating member 11 rotates relative to the bottom shell 2 to drive the swinging leaves 14 to rotate around the rotation axis, so as to change the air outlet angle of the swinging leaves 14 relative to the second air outlet 29.

[0074] The bottom shell 2 includes a bottom shell body and an air outlet seat 7, as shown in FIG. Figure 4 and Figure 5 As shown, the air outlet seat 7 is fixedly connected to the bottom shell body.

[0075] Air outlet seat 7, such as Figure 5 and Figure 6 As shown, it is designed in an inclined conical shape to enhance the smoothness of the airflow. The air outlet is equipped with two air outlets: a first air outlet 30 and a second air outlet 29, and the air inlet is an air inlet 31. The first air outlet 30 is located in the center of the air outlet seat 7, surrounded by a bracket to form a ventilation surface. The wall of the first air duct 9 in the air outlet seat 7 is evenly distributed with a plurality of grooves along the circumferential direction to support the swinging blades 14.

[0076] Rotating member 11, such as Fig.11 As shown, it includes a second motor 13 and a rotating wheel 12. The second motor 13 is used as a power source to drive the rotating wheel 12 to rotate. The rotating wheel 12 is arranged circumferentially along the second air duct 8 and meshes with the swinging blade 14. Specifically, the rotating wheel 12 is designed to be annular and is a 360° full-circumference gear, which is installed between the bottom shell body and the air outlet seat 7. Driven by the second motor 13, the rotating wheel 12 can rotate, thereby driving the swinging blade 14 meshed therewith to adjust its air outlet angle relative to the second air outlet 29.

[0077] Page 14 of the swing wind Fig.12 As shown, it is a fan-shaped structure, one end of which is provided with a rotating shaft 17, and the rotating shaft 17 is sleeved in a groove on the wall of the first air duct 9. The other end of the swing leaf 14 is a rotating shaft 17 with a driven wheel 16. The driven wheel 16 is designed as a gear that matches the rotating wheel 12 to ensure that the two can mesh and transmit power. When the rotating wheel 12 rotates, the meshing action between the gears can drive the swing leaf 14 to swing around its rotating shaft 17, thereby adjusting the air outlet direction. Figures 13 to 15 As shown, the second air outlet 29 can realize 360° multi-angle air supply.

[0078] In this embodiment, the air outlet device further improves the control accuracy and stability of the air outlet angle through the meshing transmission between the rotating wheel 12 and the driven wheel 16. The rotation of the rotating member 11 on the bottom shell 2 is transmitted to the driven wheel 16 on the swing leaf 14 through the rotating wheel 12, driving the swing leaf 14 to rotate smoothly around its rotation axis, thereby achieving continuous and smooth adjustment of the air outlet angle, thereby achieving control of the air outlet angle.

[0079] like Figures 4 to 6 As shown, the air outlet cover 10 is disposed on the first air outlet 30, and a mounting hole is provided in the center of the air outlet cover 10 for mounting the first motor 21. Figures 16 to 18 As shown, the air outlet cover 10 is provided with a grille 28 with an olive-shaped cross section. The design of the grille 28 with an olive-shaped cross section helps to optimize the distribution of the airflow. Compared with the traditional straight or square grille 28, the grille 28 with an olive-shaped cross section can more effectively guide the airflow direction, reduce the turbulence and eddy flow of the airflow at the air outlet, and reduce the wind resistance and noise level.

[0080] In this embodiment, the air outlet device realizes dual regulation of airflow through the design of the first air duct 9 and the second air duct 8 working independently or in coordination. The first air duct 9 is located in the center, providing a direct and concentrated air supply effect. The air outlet control structure of the first air duct 9 flexibly adjusts the air outlet volume to meet the needs of different users for the air outlet area. The second air duct 8 is arranged around the first air duct 9, and its control structure uses the rotating member 11 to drive the swinging leaf 14 to rotate, and can adjust the air outlet angle arbitrarily within the range of 360°, thereby enhancing the diversity and coverage of air supply.

[0081] In the present air outlet device, the first air duct 9 surrounded by the second air duct 8 forms two independent air supply channels, inner and outer. The inner second air duct 8 has an independent control system, which not only retains the ability to supply air from both inner and outer air outlets at the same time, but also allows the user to selectively open or close the air supply function of any air duct according to actual needs, thereby meeting the air supply needs in different scenarios and enhancing the user experience.

[0082] The specific implementation of the air outlet device is as follows:

[0083] like Fig.16 As shown, it is a multi-angle air supply mode. The second motor 13 drives the rotating member 11 to drive the swinging leaves 14 of the second air outlet 29 to unfold, and at the same time, the air outlet control structure of the first air duct 9 is used to open the rotating leaves 18 of the first air outlet 30, so that the first air outlet 30 is in a closed state. At this time, the hot air can be supplied 360° around the second air outlet 29, effectively preventing the user from being directly blown by the strong wind from the first air outlet 30 when bathing, thereby improving the bathing comfort.

[0084] like Fig.17As shown, it is an omnidirectional air supply mode. While keeping the swinging leaves 14 of the second air outlet 29 fully open, adjust the rotating leaves 18 of the first air outlet 30 to a contracted state, so that the first air outlet 30 is in an open state, so that the hot air can be widely spread to the bathroom space through the second air outlet 29, and can also be supplemented by air supply through the first air outlet 30. This method has a large air outlet area and a wide air supply range, and can quickly and evenly heat the bathroom space, ensuring the warmth and comfort of the entire bathroom.

[0085] like Fig.18 As shown, it is the centralized air supply mode. Close the swinging leaves 14 of the second air outlet 29, and adjust the rotating leaves 18 of the first air outlet 30 to the contracted state at the same time, so that the first air outlet 30 is in the open state, so that the hot air is mainly concentrated and blown out from the first air outlet 30. As the air outlet area is reduced, the wind speed is correspondingly increased. This method is suitable for quickly drying hair and water droplets on the body after bathing, providing high-intensity local air supply, and meeting the user's demand for quick drying.

[0086] Through the above three different working modes, the air outlet device can flexibly meet the needs of users in different scenarios, which not only ensures a comfortable experience during bathing, but also takes into account the need for quick drying after bathing, greatly improving the practicality and user experience of bathroom equipment.

[0087] Embodiment 4

[0088] A bathroom heater, such as Figure 1 and Figure 2 As shown, it includes a housing, a fan 4, a heating element 6, a lamp and the above-mentioned air outlet device. The bottom shell 2 is fixedly connected to the housing, the fan 4 is used to form wind flow, and the lamp is used for lighting; specifically, the housing includes a housing body 1 and a lamp panel 3, and the lamp panel 3 is provided with a clearance space 32 for the second air outlet 29 of the air outlet seat 7 to communicate with the outside, and the housing body 1 is fixedly connected to the air outlet device and then fixedly connected to the lamp panel 3. Other functions of the bathroom heater, such as exhaust and other functions, belong to the existing technology and will not be repeated.

[0089] like Figures 1 to 3 As shown, the shell is provided with a main air duct 5, one end of the main air duct 5 is connected to the fan 4, and the other end is connected to the second air duct 8 and the first air duct 9 along the first direction and directly faces the first air duct 9. Specifically, the shell body 1 is provided with the main air duct 5, the heating element 6 is installed between the fan 4 and the main air duct 5, and the main air duct 5 is connected to the air inlet 31 of the air outlet seat 7. When the fan 4 is working, the wind is heated by the heating element 6 from the fan 4, and then passes through the main air duct 5 and enters the air outlet device from the air inlet 31 of the air outlet seat 7, and finally blows out through the first air outlet 30 and the second air outlet 29; one end of the main air duct 5 is connected to the fan 4, and the other end is connected to the air outlet seat 7. The first air outlet 30 is located in the middle of the air outlet seat 7 and is aligned with the air outlet of the main air duct 5.

[0090] The main air duct 5 adopts a curved surface design, with a semicircular arc at the top and a plurality of circular arc surfaces at the bottom. In this embodiment, the curved surface of the air duct is gradually changed to reduce wind resistance and improve the flow efficiency of the airflow. The smooth transition of the curved surface of the air duct reduces the energy loss and turbulence of the airflow during turning and accelerating, so that the airflow can pass through the air duct more smoothly and reach the predetermined air outlet speed and direction.

[0091] In this embodiment, the bathroom heater connects the fan 4 and the air outlet device through the main air duct 5 to form an air flow transmission system, realizing a single-duct dual-outlet air supply system. The main air duct 5 faces the first air duct 9, ensuring that high-speed, concentrated airflow can directly enter the first air duct 9 and achieve a direct blowing effect. At the same time, the second air duct 8 surrounds the first air duct 9 and realizes multi-angle air supply through the swinging leaf 14, enhancing the diversity and flexibility of air supply.
