[0032] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0034] The air outlet of the air-heated bathroom heater is generally set as a single-side long and short side outlet, or a circular outlet. The air-heated bathroom heater can only continuously deliver warm air to one area. However, the bathroom is usually separated into dry and wet areas. Especially for bathrooms that require different areas to be heated separately, the air-heated bathroom heater in the related art cannot achieve different modes of heating for different areas.

[0035] Based on this, an embodiment of the present application provides an air supply device, and the air supply device is described in detail through a specific embodiment below:

[0036] Reference Figures 1 to 4 As shown, this embodiment provides an air supply device, including a first box body 1, a bottom plate 2 and a damper plate 5. The first box body 1 has a connecting surface 11, and an opening is provided on the connecting surface 11. The bottom plate 2 and the connecting surface 11 are arranged at intervals. A plurality of connecting plates 3 are provided on the bottom plate 2, and each connecting plate 3 is connected between the bottom plate 2 and the connecting surface 11. The plurality of connecting plates 3 are distributed at intervals along the circumference of the opening, and two adjacent connecting plates 3, the bottom plate 2 and the connecting surface 11 enclose a ventilation channel 4.

[0037] There are multiple damper plates 5, each ventilation channel 4 is provided with a damper plate 5, and the damper plate 5 is rotatably arranged in a ventilation channel. The damper plate 5 is rotatably connected to the bottom plate 2 or the damper plate 5 is rotatably connected to the connecting plate 3. One end of the damper plate 5 away from the bottom plate 2 is in contact with the connecting surface 11, so that when the multiple damper plates 5 distributed around the opening are closed, they can form a closed air flow cavity with the first box body 1. Each damper plate 5 can be rotated relative to the bottom plate 2 or the connecting plate 3 to adjust the opening of the corresponding ventilation channel 4, such as Figure 2 As shown, Figure 2 The damper plate 5a is in an open state, and the damper plate 5b is in a closed state.

[0038] After the air supply device provided in this embodiment is installed in the bathroom, the hot air delivery in different areas can be controlled by controlling the opening and closing of the damper plates 5 of the ventilation channels 4 in different areas, thereby realizing zoned air supply. The hot air flow rate output from the air outlet of each ventilation channel 4 can be realized according to the angle of rotation of the damper plates 5, thereby further controlling the hot air flow rate of the multiple ventilation channels 4 in the corresponding area, and meeting the requirements of a dry and wet separated bathroom for multiple heating modes in different areas.

[0039] In specific implementation, in some embodiments, a rotating shaft and a motor are provided between the base plate 2 and the damper plate 5, the motor is drivingly connected to the rotating shaft, the rotating shaft is connected to the damper plate 5, and the motor and the rotating shaft are both embedded in the base plate 2, so that the damper plate 5 can rotate relative to the base plate 2 when driven by the motor, thereby adjusting the air flow rate of the corresponding ventilation channel 4.

[0040] Multiple spaces in the bathroom that need to be heated separately correspond to multiple air supply areas of the bathroom heater. One heating space in the bathroom corresponds to multiple ventilation channels 4 in one area of ​​the bathroom heater, and multiple damper plates 5 corresponding to the multiple ventilation channels 4 are uniformly controlled. Compared with setting one ventilation channel 4 in one area of ​​the bathroom heater, when multiple ventilation channels 4 are set in one area, the length of each damper plate 5 is shortened. When the damper plate 5a rotates to Figure 2 In the middle state, the damper plate 5a is not too long, which reduces the driving load of the motor corresponding to the damper plate 5a and also reduces the time required for the damper plate 5a to rotate to the middle state. Figure 2 The space required in the middle state makes it easier to install the bathroom heater in a limited space. At the same time, when the damper plate 5 of one of the multiple ventilation channels 4 in an area fails to rotate, it will not have a significant impact on the air supply in the area.

[0041] In some embodiments, Figure 4 As shown, the cross-section of the base plate 2 is elliptical. Compared with the rectangular base plate 2, the elliptical base plate 2 allows the warm airflow output by multiple ventilation channels 4 to be distributed at all angles, avoiding dead corners without warm airflow output, and heating the corresponding areas in the bathroom more evenly.

[0042] Considering that the bathroom heater is usually embedded in the ceiling of the bathroom, and considering the aesthetics of the ceiling, in some embodiments, Figure 1 and Figure 2 As shown, the edge of the connecting plate 3 is flush with the edge of the bottom plate 2 in the thickness direction of the bottom plate 2, so as to avoid one end of the connecting plate 3 that forms the ventilation channel 4 protruding from the bottom plate 2, which would make the bathroom heater unsightly when people in the bathroom look at the ceiling.

[0043] In some embodiments, the bottom plate 2 and the connecting plate 3 are an integrally formed structure. The bottom plate 2 and the connecting plate 3 can be machined or injection molded into an integrally formed structure, which increases the connection strength between the bottom plate 2 and the connecting plate 3 and reduces the difficulty of assembly.

[0044] Another embodiment of the present application provides a bathroom heater with controllable partitioned air supply, including the above-mentioned air supply device, a fan 6 and a heating component 7 are arranged in the first box 1, an air inlet is arranged on the side wall of the first box 1 opposite to the opening, the external airflow enters the first box 1 through the air inlet, the heating component 7 heats the airflow in the first box 1 to form a warm airflow, and the warm airflow flows out to the external space through the ventilation channel 4 at the opening. The fan 6 can promote the flow of airflow in the first box 1, so that the heating component 7 can evenly heat the airflow in the first box 1, and the fan 6 is also conducive to the cold airflow entering from the air inlet and the warm airflow flowing out from the ventilation channel 4.

[0045] Usually, the bathroom heater is a rectangular parallelepiped structure, so in some embodiments, such as Figure 3As shown, at least two fans 6 are provided, and at least two fans 6 are spaced apart along the length direction of the first box body 1. This prevents the airflow in the local space of the bathroom heater from flowing slowly due to being away from the fans 6. A heating component 7 is provided between two adjacent fans 6 to prevent the airflow in the area of ​​the bathroom heater away from a single heating component 7 from not being heated up in time due to the lack of a heating component 7, and flowing out of the ventilation channel 4 before being heated up, thereby affecting the heating effect in the bathroom.

[0046] In some embodiments, the heating assembly 7 includes a plurality of heating sheets, and the two ends of each heating sheet are respectively plugged into the side walls of the first box body 1 on two opposite sides along the width direction thereof. Exemplarily, the heating sheet can be a PTC heating sheet, which has a large contact area with the air and can quickly and evenly heat the airflow in the area.

[0047] In some embodiments, Figure 2 and Figure 3 As shown, the air supply device also includes a second box 8, and the first box 1 is located in the second box 8. The second box 8 protects the first box 1, and the area between the second box 8 and the first box 1 is used to arrange some electrical components and power supplies, which need to dissipate heat and are not easy to be in hot air. A space for forming a hot air flow is separately set in the second box 8, and the air between the first box 1 and the second box 8 is not heated, so the electrical components and power supplies located between the second box 8 and the first box 1 will not be affected by the hot air flow.

[0048] The opening of the second box body 8 is provided with a cover plate 9, and the cover plate 9 is detachably connected to the second box body 8. Figure 2 As shown, the cover plate 9 is provided with a fixing hole 91, the outer contour of the bottom plate 2 corresponds to the fixing hole 91, the bottom plate 2 and the cover plate 9 are connected by the connecting plate 3, and the bottom plate 2 is located outside the cover plate 9, so that the air outlet end 41 of the ventilation channel 4 can circulate with the external air. Figure 1 and Figure 4 As shown, when the bottom plate 2 is elliptical, the fixing hole 91 is an elliptical hole.

[0049] Considering that when the air-heated bathroom heater is installed on the ceiling of the bathroom, the air-heated bathroom heater is usually embedded in the ceiling. In order to facilitate embedding the second box body 8 in the ceiling, the second box body 8 is a cube.

[0050] In some embodiments, the cover is embedded in the second box, and a built-in buckle is provided at the connection between the second box and the cover. The second box and the cover are connected by the built-in buckle, so that the part of the bathroom heater exposed on the ceiling is more beautiful. In specific implementation, the slot of the built-in buckle is provided on the inner wall of the second box, and the connecting protrusion of the built-in buckle is provided on the outer peripheral surface of the cover. There are multiple built-in buckles, and the multiple built-in buckles are evenly spaced along the circumference of the cover.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0052] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
