[0027] The double-arc structure air damper assembly of the present application is mainly used for a bathroom heater, so that the air entering from the air inlet duct can flow out from the heating air outlet or the ventilation air outlet. The double-arc structure air damper assembly adopts an arc structure at the rotational mating part between the air damper and the heater base. This arc structure not only better controls the deformation amount at the mating part between the air damper and the heater base, but also can improve the coaxiality of rotation between the two, making the rotational operation smooth. In addition, with the improvement of coaxiality, the air damper and the heater base adopt a lapped edge structure around, so that the air damper can very effectively reduce the air leakage from the side wall whether in the ventilation or heating state, further increasing the ventilation air volume.

Figure 6 is a perspective view of an air damper and an air damper seat after installation according to an exemplary embodiment of the present disclosure.
[0029] According to an exemplary embodiment of the present application, as Figures 1-6 shown, the double-arc structure air valve assembly 1 includes: an air valve 10, the air valve 10 includes a rotating member 11 located on one side and having an arc shape and a plate-shaped main body 12 adjacent to the rotating member 11, and the air valve 10 can rotate around its said one side to guide air to flow along different paths; an air valve seat 20, the air valve 10 is rotatably mounted to the air valve seat 20, the air valve seat 20 includes a rotating support portion 21 and an opening 22, wherein, the rotating support portion 21 has an arc shape and bears the rotating member 11 of the air valve 10, and the shape of the opening 22 matches that of the plate-shaped main body 12 and the area is smaller than the area of the plate-shaped main body 12.
[0030] This double-arc structure air valve assembly realizes an air valve switching structure with high sealing performance and high coaxiality.
[0031] Specifically, the air valve 10 is generally plate-shaped, the rotating member 11 and the plate-shaped main body 12 are an integral part, and the rotating member 11 having a certain angle with the plate-shaped main body 12 is provided on one side of the air valve 10, so that the air valve 10 can rotate around the air valve seat 20 to guide air to flow in different directions. As Figure 5 and 6 shown, when the rotating member 11 is located on the rotating support portion 21, the two opposite members are both arc surfaces, and the axes corresponding to the two arc surfaces are the same axis. In other words, the two arc surfaces are coaxially arranged. The overall shape of the air valve seat 20 matches that of the air valve 10, and a rotating support portion 21 capable of supporting the rotating member 11 is provided on one side. An air valve seat plate extends from the rotating support portion 21, and an opening 22 is provided on the panel of the air valve seat. The shape of the opening 22 is the same as that of the plate-shaped main body 12 and is smaller than the plate-shaped main body 12, so that the air valve main body can be supported by the air valve seat 20. The air valve seat is provided with orifices at both ends of the air valve for receiving the rotating shaft of the air valve 10. When the air valve 10 rotates, air flows out through the opening 22. When the air valve 10 is supported on the air valve seat 20, the opening 22 is blocked by the air valve 10, realizing another air flow path, and thus passing through different air outlets 30. As shown in the figure.
[0032] In one embodiment of the present disclosure, the rotating member 11 includes cylindrical rotating shafts 111 located at both ends and an arc-shaped rotating member 112 located between the cylindrical rotating shafts 111, and the axes of the cylindrical rotating shafts 111 and the arc-shaped rotating member 112 are coaxial. Specifically, one end of the rotating member 11, such as the cylindrical rotating shaft, is connected to the air valve seat 20, and preferably, it can be inserted into the orifice of the air valve seat 20. One end of this rotating member 11 is one of the rotating shafts 111 in the cylindrical rotating shafts 111, and a sheet-shaped limiting member 1111 can be provided on the outer surface of the cylindrical rotating shaft 111 to limit the longitudinal position of the arc-shaped rotating member 112 relative to the air valve seat 20, and the limiting member 1111 protrudes outward along the circumferential direction from a part of the outer surface. The other end of the rotating member, for example, the cylindrical rotating shaft, is connected to the driving motor 40, so as to rotate under the drive of the motor. The other end can also be the cylindrical rotating shaft 111 or a hollow rotating shaft, and can be connected to the drive shaft of the motor 40 through various keys such as splines. Alternatively, the arc-shaped rotating member 112 can be a hollow tube cut along the axis.
[0033] For the air valve 10 and the air valve seat 20 according to this embodiment, especially at the rotational mating part of the air valve 10 and the air valve seat 20, an arc structure is adopted, as Figures 4-6 shown, which can not only well control the deformation amount at the mating part of the air valve 10 and the air valve seat 20, but also improve the coaxiality of rotation between the two.
[0034] In one embodiment of the present disclosure, the angle between the arc-shaped rotating member 112 and the plate-shaped main body 12 corresponds to the angle between the rotating support portion 21 and the air valve seat plate, so that when the arc-shaped rotating member 112 is supported on the rotating support portion 21, the plate-shaped main body 12 can block the opening 22 of the air valve seat 20.
[0035] In one embodiment of the present disclosure, at least one recess 1121 is provided on the arc-shaped rotating member 112 for accommodating the protruding member of the air valve seat 20. A plurality of protruding members 211 can also be provided on the air valve seat 20 to enhance the strength of the air valve seat. The protruding member 211 is perpendicularly arranged with respect to the rotating support portion 21, and when the air valve 10 rotates, the protruding member 211 can be accommodated in the above-mentioned recess 1121. The number of the recesses 1121 can correspond to the number of the protruding members 211.
[0036] In one embodiment of the present disclosure, the plate-shaped main body 12 is provided with a reinforcing rib 121 on the side opposite to the rotating member 11. The reinforcing rib 121 can increase the strength of the air valve 10 and can also make the air valve 10 fit more closely to the air valve seat 20 when the air valve 10 is placed on the air valve seat 20, thereby reducing the air leakage around the air valve 10.
[0037] In one embodiment of the present disclosure, the damper seat plate of the air valve overlaps with the periphery of the plate-shaped main body 12 around the periphery of the opening 22 by a width. Thus, the air valve 10 and the damper seat 20 form a lap joint structure, which not only reduces air leakage, but also increases the air volume of the product as a whole, improves the performance, and ultimately enhances the user experience and the recognition of the product by the customers.
[0038] In one embodiment of the present disclosure, the air valve 10 can rotate around the damper seat 20 by at least 60 degrees and at most 75 degrees. Preferably, it is 65 degrees or 70 degrees.
[0039] In one embodiment of the present disclosure, the damper seat 20 is provided on the heater base. In other words, a rotating support portion 21 and an opening 22 can be provided on the heater base so that the air valve 10 can be installed on the heater base.
[0040] Figure 7A and Figure 7B are schematic diagrams of the double-arc structure air valve assembly in different rotation states according to the exemplary embodiments of the present disclosure.
[0041] On the other hand, the present application also provides a bathroom heater, including the double-arc structure air valve assembly 1 as described above. As Figure 7A and Figure 7B shown, for the bathroom heater adopting the above double-arc structure air valve assembly 1, the rotation coaxiality of the air valve is improved, avoiding the air valve from rotating smoothly or getting stuck during rotation. And with the improvement of the coaxiality, when the air valve switches between heating and ventilation, the air valve fits well with the surrounding lap joint structure, improving the sealing effect, reducing air leakage, increasing the air volume of the product as a whole, improving the performance, and thus enhancing the user experience and the recognition of the product by the customers.
