[0057] In addition, it should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0058] Please refer to Figures 1 to 21 as shown, for the bathroom warmer 100 of the present invention.

[0059] Embodiment 1:

[0060] The bathroom warmer 100 includes a conversion frame 1, an air duct assembly 200, an inner ring module 4 and a warm air main unit 5. The conversion frame 1 is used to mount the bathroom warmer 100 onto a mounting base 6. The air duct assembly 200 includes an air duct structure 2 and an outer ring module 3. The air duct structure 2 is disposed below the mounting base 6 and at least partially exposed outside the mounting base 6, and is detachably connected to the warm air main unit 5. The outer ring module 3 is detachably connected to the outside of the air duct structure 2. The inner ring module 4 is disposed inside the air duct structure 2. The warm air main unit 5 is disposed in the installation space above the mounting base 6. The bathroom warmer 100 adopts an annular air outlet mode, making the indoor temperature distribution more uniform.

[0061] In this embodiment, the mounting base 6 is made of materials such as gypsum board or honeycomb large board. At this time, when installing the bathroom warmer 100, a separate hole needs to be opened on the mounting base 6, and the warm air main unit 5 is hidden inside the mounting base 6. The setting of the conversion frame 1 can block the hole on the mounting base 6, making the appearance of the bathroom warmer 100 more beautiful and having a stronger overall sense.

[0062] Specifically, the mounting base 6 is provided with an opening 61, and there is an installation space above the mounting base 6 for accommodating the warm air main unit 5 of the bathroom warmer 100.

[0063] The conversion frame 1 includes a frame body 11 and a bracket 12, and the bracket 12 is rotatably connected to the frame body 11. The conversion frame 1 further includes a rotating member 13. A first rotating hole 1111 is provided on the top wall 111, and a corresponding second rotating hole 121 is provided on the bracket 12. The rotating member 13 sequentially passes through the first rotating hole 1111 and the second rotating hole 121 to rotatably connect the bracket 12 and the frame body 11.

[0064] The frame body 11 includes a top wall 111 facing the mounting base 6. An installation opening 112 is provided on the inner side of the top wall 111 corresponding to the position of the opening 61, and the installation opening 112 can pass through part of the internal structure of the bathroom warmer 100.

[0065] On the outer side of the top wall 111, there is also an outer peripheral wall 114 extending away from the mounting base 6. The outer peripheral wall 114 extends downward from the top wall 111 and has a certain height. The two ends of the outer peripheral wall 114 are respectively in contact with the mounting base 6 and the outer ring module 3. A number of first grilles 1141 for air intake are provided on the outer peripheral wall 114. When the bathroom heater 100 works, cold air enters the air heating main unit 5 from the first grilles 1141. The first grilles 1141 extend from the direction away from the mounting base 6 towards the mounting base 6. The height of the first grilles 1141 should be set large enough to ensure sufficient air intake, so as to enable the bathroom heater 100 to achieve sufficient air output. Moreover, the setting of the outer peripheral wall 114 can fix the distance between the outer ring module 3 and the mounting base 6, ensuring the air intake of the bathroom heater 100.

[0066] Furthermore, a number of second grilles 1112 arranged at intervals are provided on the top wall 111. The second grilles 1112 are arranged close to the mounting opening 112 and at least partially located inside the opening 61. The setting of the second grilles 1112 makes the bathroom heater 100 more breathable. In other embodiments, the second grilles 1112 may not be provided.

[0067] On the inner side of the top wall 111, there is a limiting wall 113 extending towards the mounting base 6. The limiting wall 113 is configured to limit the rotation angle of the limiting bracket 12.

[0068] The bracket 12 is arranged on the side of the top wall 111 facing the mounting base 6 and is rotatably connected to the top wall 111. It is configured to fixedly connect the air heating main unit 5 to the mounting base 6 and fixedly connect the air heating main unit 5 and the duct structure 2.

[0069] The bracket 12 has a first position and a second position. In the first position, at least part of the orthographic projection of the bracket 12 is located inside the mounting opening 112 to enter the interior of the mounting base 6 through the mounting opening 112. In the second position, at least part of the orthographic projection of the bracket 12 is located outside the top wall 111 to fixedly connect the bathroom heater 100 to the mounting base 6 through the bracket 12 and fixedly connect the air heating main unit 5 and the duct structure 2 of the bathroom heater 100.

[0070] Specifically, the bracket 12 includes a first part 122 rotatably connected to the top wall 111, a second part 123 extending from the first part 122 towards the mounting base 6, and a third part 124 arranged at an angle to the second part 123 and used for fixing the air heating main unit 5 and the duct structure 2. The second part 123 includes a first plate 1231 extending vertically and a second plate 1232 extending horizontally from the first plate 1231. The first part 122 is connected to the first plate 1231, and the third part 124 is connected to the second plate 1232.

[0071] An assembly hole 1233 is provided at one end of the first plate 1231 away from the first part 122. When the bracket 12 is in the second position, the fastener passes through the assembly hole 1233 to fix the bracket 12 to the mounting mechanism 62 in the installation space, thereby fixing the bathroom heater 100 to the installation base 6. In this embodiment, the mounting mechanism 62 is a wooden strip, which is directly supported on the keel.

[0072] There is a yield portion 125 between the second plate 1232 and the first portion 122, and the yield portion 125 is configured to allow the installation base 6 to pass through, that is, the second plate 1232 is at a certain distance from the top wall 111, and this distance is greater than the height of the installation base 6, so as to prevent the part of the orthographic projection that exceeds the top wall 111 from colliding with the installation base 6 when the bracket 12 rotates to the second position.

[0073] The first portion 122 is provided with a second fixing hole 1221 , and the top wall 111 is correspondingly provided with a first fixing hole 1113 . When the bracket 12 is in the second position, the first fixing hole 1113 overlaps with the second fixing hole 1221 , and the bracket 12 is fixed in the second position by a fastener.

[0074] The third portion 124 is provided with a connecting portion 1241 and a stopping portion 1242 . The connecting portion 1241 is used for fixing the connection between the air-heating main unit 5 and the air duct structure 2 , and the stopping portion 1242 is configured to limit the installation position of the air-heating main unit 5 .

[0075] In the present invention, a plurality of brackets 12 are provided, and the plurality of brackets 12 are arranged circumferentially along the top wall 111 .

[0076] Specifically, in the first position, the orthographic projections of the second portions 123 of the brackets 12 are located on the top wall 111 , the extended lines of the orthographic projections of the second portions 123 of the brackets 12 intersect, and the orthographic projections of the third portions 124 are located in the installation opening 112 .

[0077] In the second position, the orthographic projection of the second portion 123 is at least partially located outside the top wall 111 , the orthographic projections of the second portions 123 of the brackets 12 are arranged in parallel, and the orthographic projection of the third portion 124 is located on the top wall 111 .

[0078] In this embodiment, four brackets 12 are provided. When in the second position, the orthographic projections of the second portions 123 of the four brackets 12 are parallel to each other and are mounted on the mounting mechanism 62 . The orthographic projections of the two mounting mechanisms 62 are also parallel to each other.

[0079] The air duct structure 2 includes a shell 21 , and the shell 21 includes an outer shell 211 and an inner shell 212 . An arc-shaped air duct 22 and an annular air outlet 2121 connected to the arc-shaped air duct 22 are formed between the outer shell 211 and the inner shell 212 .

[0080] The housing 211 is provided with a second air inlet 2111. Air enters the arc-shaped air duct 22 through the second air inlet 2111 and then enters the room from the annular air outlet 2121. The shape of the arc-shaped air duct 22 is set to make the air flow more gentle. The annular air outlet mode makes the indoor temperature distribution more uniform. When the air blows on the human body, it will not cause discomfort due to too fast air speed or concentrated blowing area.

[0081] The arc-shaped air duct 22 includes a first section 221, a second section 222 and an arc section 223. The first section 221 is arranged close to the second air inlet 2111, the second section 222 is arranged close to the annular air outlet 2121, and the arc section 223 connects the first section 221 and the second section 222. Moreover, the first section 221 is in a trumpet shape, and the wide end of the first section 221 is connected to the second air inlet 2111, and the narrow end of the first section 221 is connected to the arc section 223. That is, the two ends of the arc-shaped air duct 22 are respectively provided with the second air inlet 2111 and the annular air outlet 2121. The arc-shaped air duct 22 gradually decreases from large to small, which actually plays a role in guiding the air flow, guiding the air from the second air inlet 2111 to the annular air outlet 2121. This process makes the air speed more gentle. The arc design can also make full use of the air flow, shorten the air intake path, and reduce the air volume loss.

[0082] The annular air outlet 2121 is exposed outside the installation base 6, that is, the plane where the annular air outlet 2121 is located is lower than the plane where the lower part of the installation base 6 is located.

[0083] At least two first engaging parts 23 are arranged on the housing 21 along the circumferential direction. The outer ring module 3 includes a module housing 31. The module housing 31 has an annular assembly port 311. At least two second engaging parts 32 are arranged at the position of the module housing 31 facing the assembly port 311. The outer ring module 3 and the air duct structure 2 are detachably connected through the first engaging parts 23 and the second engaging parts 32.

[0084] One of the first engaging part 23 and the second engaging part 32 includes a clearance notch 231 and a buckle part 232 arranged in sequence. The buckle part 232 includes a first clamping surface 2321. The other of the first engaging part 23 and the second engaging part 32 includes a protruding part 321 corresponding to the clearance notch 231. The protruding part 321 includes a second clamping surface 3211. The protruding part 321 slides into or out of the buckle part 232 through the clearance notch 231 so that the first clamping surface 2321 is slidably connected to the second clamping surface 3211.

[0085] In this embodiment, the outer shell 211 extends away from the inner shell 212 to form an outer edge portion 2113. The first engaging portion 23 is provided on the outer edge portion 2113 and includes a clearance notch 231 and a snap portion 232 arranged in sequence. The snap portion 232 includes a first engaging surface 2321 arranged upward and a first guiding surface 2322 arranged close to the clearance notch 231. The first guiding surface 2322 extends obliquely downward from the first engaging surface 2321 toward the clearance notch 231.

[0086] Furthermore, the second engaging portion 32 is a convex portion 321 formed by the module housing 31 extending toward the assembly port 311. The convex portion 321 includes a second engaging surface 3211 facing downward and second guiding surfaces 3212 arranged at both ends of the second engaging surface 3211. The positions of the second guiding surfaces 3212 correspond to the positions of the first guiding surfaces 2322.

[0087] One of the snap portion 232 and the convex portion 321 is provided with a limiting structure 3213, and the other of the snap portion 232 and the convex portion 321 is provided with a limiting surface 2323 corresponding to the limiting structure 3213. The limiting structure 3213 and the limiting surface 2323 cooperate to limit the sliding distance of the convex portion 321 on the snap portion 232.

[0088] In this embodiment, the limiting surface 2323 is provided on the snap portion 232. The limiting surface 2323 is adjacent to the first guiding surface 2322 and faces the clearance notch 231. The limiting structure 3213 is provided on the convex portion 321, and the limiting structure 3213 extends downward from the second engaging surface 3211.

[0089] The housing 21 is provided with a first positioning portion 2112, and the outer ring module 3 is correspondingly provided with a second positioning portion 33. One of the first positioning portion 2112 and the second positioning portion 33 includes an elastic protrusion facing each other, and the other of the first positioning portion 2112 and the second positioning portion 33 includes a card slot facing each other. In this embodiment, the first positioning portion 2112 is a card slot, and the second positioning portion 33 is an elastic protrusion.

[0090] When the outer ring module 3 and the air duct structure 2 are rotationally snapped together, after the convex portion 321 is aligned with the clearance notch 231 from below the air heater main body 5 and pushed upward to the in-place position, the outer ring module 3 is rotated counterclockwise. The second guiding surface 3212 slides into the snap portion 232 along the first guiding surface 2322, and the first engaging surface 2321 abuts against the second engaging surface 3211 until the second positioning portion 33 is snapped into the first positioning portion 2112, indicating that the rotational snap is in place. When the elastic protrusion enters the card slot, a sound will be emitted to indicate that the rotation is in place and play a certain role in preventing rotation, preventing the outer ring module 3 from accidentally falling off during use.

[0091] Further, when the air duct structure 2 is rotationally and snap-fitted with the outer ring module 3 in place, the limiting structure 3213 abuts against the limiting surface 2323, thereby limiting the outer ring module 3 to prevent the outer ring module 3 from rotating excessively and causing structural damage, greatly improving the safety of the installation process and saving costs.

[0092] A connecting member 24 is provided on the air duct structure 2, and the connecting member 24 is detachably connected to the air heating main unit 5. The connecting member 24 includes a connecting end 241 facing the air heating main unit 5, and the connecting end 241 is detachably connected to the main unit bracket 51.

[0093] Optionally, the outer ring module 3 is any one of a ring-shaped lighting assembly, a ring-shaped electrical module, a ring-shaped display module, and a ring-shaped audio module. In this embodiment, the outer ring module 3 is a ring-shaped lighting assembly, and the ring-shaped lighting assembly is disposed around the air duct structure 2.

[0094] The inner ring module 4 is disposed in the space formed by the depression of the inner shell 212 towards the outer shell 211. The size of the inner ring module 4 matches the size of this accommodating space. The plane where the inner ring module 4 is located is kept horizontal with the plane where the air duct structure 2 is located, making the ceiling lamp 100 look more beautiful and reasonably utilizing the space.

[0095] In this embodiment, the inner ring module 4 is any one of an electrical module, a display module, an audio module, and a lighting module. In other embodiments, the inner ring module 4 may not be provided either.

[0096] The air heating main unit 5 includes a main unit bracket 51, a main unit housing 52, and a frame 53. The air heating main unit 5 is detachably connected to the air duct structure 2 through the main unit bracket 51.

[0097] The main unit bracket 51 includes a fixed end 511 and a clamping end 512. The fixed end 511 is fixedly connected to the connecting member 24 on the air duct structure 2, and the clamping end 512 is fixedly connected to the frame 53 of the air heating main unit 5.

[0098] A blowing assembly 521 is provided inside the main unit housing 52. The first air inlet 5211 of the blowing assembly 521 is connected to the second air inlet 2111 through a wind guiding structure.

[0099] The wind guiding structure is arranged in an arc shape and includes a third air inlet (not shown) arranged at an angle and a first air outlet 5221. The third air inlet faces the blowing assembly 521 and is connected to the first air outlet 5221. The first air outlet 5221 faces the air duct structure 2 and is connected to the second air inlet 2111. A heating device 523 is provided at the connection between the first air outlet 5221 and the second air inlet 2111.

[0100] An air extraction component 524 is also provided inside the main housing 52. The air extraction component includes an air extraction port 5241 and an exhaust port 5242. When there is fog in the room, air enters from the air extraction port 5241 and is discharged from the exhaust port 5242.

[0101] Furthermore, the positions of the first air inlet 5211 and the air extraction port 5241 correspond to the position of the second grille 1112 on the conversion frame 1, which is more convenient for air intake.

[0102] The bathroom heater 100 of the present invention has two working modes, namely the heating and air outlet mode and the ventilation mode, and the two working modes can be turned on and work simultaneously.

[0103] Specifically, when the heating and air outlet mode is started, gas enters the bathroom heater 100 from the first grille 1141 and the second grille 1112, enters the air heating main unit 5 through the first air inlet 5211, and then is blown out from the first air outlet 5221 through the heating device 523, enters the arc-shaped air duct 22 of the air duct structure 2, and finally enters the room from the annular air outlet 2121, so that the air outlet in the room is in a ring shape, making the air outlet more uniform and avoiding discomfort caused by the hot air blowing on the human body due to overly concentrated air outlets.

[0104] When the ventilation mode is started, gas enters the bathroom heater 100 from the first grille 1141 and the second grille 1112. Then, the gas enters the air heating main unit 5 from the air extraction port 5241 and is blown out to the outside through the exhaust port 5242 to achieve ventilation.

[0105] Embodiment Two:

[0106] In this embodiment, the installation base 6 is an integrated ceiling, and the conversion frame 1 is not provided on the bathroom heater 100. The integrated ceiling is simple to install, flexible in layout, convenient for maintenance, and can overcome the deficiency of the monotonous color of the ceiling. After installing the bathroom heater on the integrated ceiling, what is seen is no longer a rigid combination but a perfectly coordinated top shape, which can overcome the embarrassment of the installation position of traditional bathroom heaters.

[0107] Specifically, the main machine bracket 51 on the air heating main unit 5 is detachably connected to the connecting piece on the air duct structure 2. Thus, the lower half of the air duct structure 2, the outer ring module 3, and the inner ring module 4 are lifted. A triangular keel is provided on the upper part of the installation base 6, and a certain number of support members 64 are fixedly connected to the frame 53. The support members 64 are clamped with the triangular keel, that is, the air heating main unit 5 is directly placed on the triangular keel.

[0108] In this embodiment, there is a gap 63 between the air duct structure 2 and the installation base 6. When the bathroom heater is working, air directly enters the interior of the bathroom heater 100 from the gap 63, and the working process is the same as that of Embodiment One.

[0109] In summary, the air heating main unit 5 of the integrated ceiling heater 100 of the present invention is detachably connected to the air duct structure 2, and the air duct structure 2 is rotationally clamped to the outer ring module 3, making the installation of the integrated ceiling heater 100 more convenient. Moreover, the outer ring module 3 and the inner ring module 4 can be expanded with various types of modules, such as audio modules, display modules, etc., making the functions of the integrated ceiling heater 100 more diversified and intelligent.

[0110] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
