Description

Technical Field

[0001] The utility model relates to the technical field of bathroom heating and lighting structures, in particular to a fan structure capable of adjusting wind direction and a bathroom heater comprising the fan structure. Background Art

[0002] Nowadays, many people install a bathroom heater in their bathroom. A bathroom heater usually includes a heating device and a lighting device to provide heating and lighting for the user. The heating device usually includes a heating module and a fan structure. After the heating module heats the nearby air, the fan structure blows the heated air toward the user.

[0003] However, the hot air direction of the heating device in the above-mentioned bathroom heater is fixed and cannot be adjusted. It may blow towards a certain part of the user's body, causing discomfort to the user. In addition, the adaptability of the air outlet angle is different for different users, which is not conducive to optimizing the user experience. Therefore, in order to adjust the angle of the hot air, the designer added an air guide plate to the fan structure. The air guide plate is arranged on the shell of the bathroom heater and located on the front side of the heating module. The air guide plate can be rotated to adjust the wind direction of the hot air blown out.

[0004] The above-mentioned existing bathroom heater with a fan structure capable of adjusting wind direction has at least the following disadvantages:

[0005] 1. This fan structure with adjustable wind direction adopts a split design and needs to be installed separately. For example, in the structure of a bathroom heater, the main wind-generating part of the fan structure is located on the back side of the heating module, and the wind guide plate for wind direction adjustment is located on the front side of the heating module. Therefore, the installation steps of this fan structure are relatively cumbersome and inconvenient in transportation and storage.

[0006] 2. Due to considerations of weight, energy consumption and other reasons, the air guide plate is generally made of plastic, and the maximum temperature of the heating module can reach 180°C. Therefore, the air guide plate is easy to turn yellow and brittle, and is easily damaged. The air guide plate often needs to be repaired or replaced, resulting in a generally short lifespan of the fan structure with adjustable wind direction in this type of bathroom heater, which is not conducive to optimizing the user experience and increases the user's cost of use.

[0038] like Figures 1 to 8 As shown, a fan structure 10 with adjustable wind direction includes a mounting plate 1, an adjustment seat 2, a fan body 3 and a wind direction adjustment device 4, wherein the adjustment seat 2 is arranged on the mounting plate 1, and the fan body 3 is rotatably connected to a side of the adjustment seat 2 away from the mounting plate 1; the wind direction adjustment device 4 includes an elastic support assembly 44, an adjustment motor 42 and an adjustment rod 43, the elastic support assembly 44 includes a plurality of elastic support members 41, the adjustment seat 2 is installed on the mounting plate 1 through the plurality of elastic support members 41, and a protrusion assembly 21 is provided on a side of the adjustment seat 2 close to the mounting plate 1, and the protrusion assembly 21 includes a plurality of first protrusions arranged along an arc or a circumference at intervals. A protrusion 211, the adjusting motor 42 is arranged on the mounting plate 1 and is located on the inner side of the protrusion assembly 21, the adjusting rod 43 includes a fixed end 431 and an adjusting end 432, the fixed end 431 is arranged on the output end of the adjusting motor 42, and the adjusting end 432 is provided with a lifting portion 433 matching the first protrusion 211, and the lifting portion 433 is located between the adjusting seat 2 and the mounting plate 1; when adjusting, the adjusting motor 42 drives the adjusting rod 43 to rotate, so that the lifting portion 433 lifts one of the first protrusions 211, so that the adjusting seat 2 is tilted relative to the mounting plate 1 or changes the tilt direction to adjust the air outlet direction of the fan body 3.

[0039] When the wind direction needs to be adjusted, the adjusting motor 42 drives the adjusting rod 43 to rotate, and one of the first protrusions 211 is lifted up by the lifting portion 433, so that the adjusting seat 2 is tilted, and the fan body 3 is driven to tilt. The lifting portion 433 lifts different first protrusions 211, and the adjusting seat 2 will obtain different tilt directions, so that the fan body 3 can blow air in different directions. In the utility model, the connection between the various parts of the fan structure 10 is closer, so that the integrity of the fan structure 10 is stronger, and it is more convenient to install the fan structure 10 on the corresponding device, which is conducive to simplifying the installation steps, improving the efficiency of device assembly and production, and also facilitating the transportation and storage of the fan structure 10.

[0040] In some specific embodiments, reference Figure 2 and Figure 8The elastic support member 41 includes a screw member 411 and a spring member 412 sleeved on the screw member 411, and a thread is provided on the end of the screw member 411 away from the head; a first mounting hole 11 is provided on the mounting plate 1, and a second mounting hole 24 is provided on the adjustment seat 2. The screw member 411 passes through the first mounting hole 11 and is spirally connected to the second mounting hole 24. The screw member 411 can move axially in the first mounting hole 11, and the spring member 412 is arranged between the mounting plate 1 and the head of the screw member 411.

[0041] Specifically, the first mounting hole 11 is a through hole, and the second mounting hole 24 is a screw hole. After the screw 411 passes through the through hole, the threaded end thereof is screwed into the screw hole, and the adjustment seat 2 can be mounted on the mounting plate 1 .

[0042] Take the fan structure 10 in the bathroom heater as an example: in the bathroom heater, the mounting plate 1, the adjustment seat 2 and the fan body 3 of the fan structure 10 are arranged from top to bottom, and the wind direction is generally downward. When one of the first protrusions 211 is lifted up by the lifting portion 433, the first protrusion 211 moves downward, and the screw member 411 on the elastic support member 41 at the position corresponding to the first protrusion 211 will further extend into the mounting plate 1. At this time, the spring member 412 is further compressed to limit the downward movement of the adjustment seat 2. When the lifting portion 433 is separated from the first protrusion 211, the spring member 412 will return to its original state, so that the first protrusion 211 that was originally lifted up moves upward and resets, thereby resetting the adjustment seat 2 and the lamp body.

[0043] In some specific embodiments, reference Figure 1 , Figure 5 and Figure 8 The multiple elastic support members 41 correspond to the multiple first protrusions 211 one by one, and the elastic support members 41 are arranged beside the corresponding first protrusions 211.

[0044] Specifically, in this embodiment, eight first protrusions 211 are provided on the adjustment seat 2 , and the adjustment seat 2 is mounted on the mounting plate 1 via eight elastic support members 41 .

[0045] The number of elastic support members 41 is the same as that of the first protrusions 211. The elastic support members 41 are arranged beside the corresponding first protrusions 211, which is conducive to providing sufficient resetting elastic force for the resetting of the first protrusions 211, ensuring that the adjustment seat 2 and the fan body 3 can be smoothly reset after the top part 433 is separated from the first protrusion 211.

[0046] In some specific embodiments, reference Figure 6 The adjustment seat 2 includes a circular adjustment base plate 22 , and a plurality of first protrusions 211 are disposed on the adjustment base plate 22 and are evenly spaced around the axis of the adjustment base plate 22 .

[0047] Specifically, the plurality of first protrusions 211 are evenly spaced along the circumference around the axis of the adjusting base plate 22. With such arrangement, when the adjusting motor 42 controls the adjusting rod 43 to rotate at a constant speed, the time for the protruding portion 433 to reach the adjacent first protrusion 211 from one first protrusion 211 is substantially the same, and the direction change of the fan body 3 is easily controlled.

[0048] In this embodiment, when the protrusion is located between two adjacent first protrusions 211, the adjustment base plate 22 is substantially parallel to the mounting plate 1, and the axis of the rotating shaft of the adjustment motor 42 is substantially on the same straight line as the axis of the adjustment base plate 22. This arrangement is conducive to enabling the top portion 433 to fully contact each first protrusion 211, ensuring that the set inclination angle is reached in different inclination directions to achieve wind direction adjustment.

[0049] When the lifting portion 433 moves from between two adjacent first protrusions 211 to the corresponding position of one of the first protrusions 211 and lifts the first protrusion 211, the adjustment base plate 22 changes from a state relatively parallel to the mounting plate 1 to a state relatively inclined to the mounting plate 1; when the lifting portion 433 moves from the corresponding position of one of the first protrusions 211 to the corresponding position of the other first protrusion 211, that is, switches from the state of lifting one of the first protrusions 211 to the state of lifting the other first protrusion 211, the inclination direction of the adjustment base plate 22 changes.

[0050] In some specific embodiments, reference Figure 3 and Figure 8 A second protrusion 434 is provided on one side of the top raising portion 433 close to the adjusting base plate 22, a hemispherical surface 435 is provided on one end of the second protrusion 434 close to the adjusting base plate 22, an arcuate surface 2111 is provided on one end of the first protrusion 211 close to the mounting plate 1, one end of the arcuate surface 2111 is connected to the adjusting base plate 22, and the other end extends radially around the adjusting base plate 22 and is connected to the adjusting base plate 22.

[0051] When adjusting the angle of the fan body 3, the lifting portion 433 moves circumferentially around the axis of the adjusting base plate 22. In the process of lifting the first protrusion 211, the hemispherical surface 435 on the second protrusion 434 cooperates with the arcuate surface 2111 on the first protrusion 211 until the top of the second protrusion 434 contacts the top of the first protrusion 211, and the first protrusion 211 is completely lifted. The hemispherical surface 435 is provided on the second protrusion 434 and the arcuate surface 2111 is provided on the first protrusion 211, so that the lifting portion 433 is subjected to less resistance in the process of completely lifting the first protrusion 211, and the fan body 3 can be tilted relative to the mounting plate 1 more smoothly, and the tilting direction of the fan body 3 can be adjusted more smoothly to adjust the wind direction of the fan structure 10. In addition, it is also helpful to reduce the probability of damage to the fan structure 10 and to extend the service life of the fan structure 10.

[0052] In some other embodiments, the two ends of the arc surface 2111 on the first protrusion 211 are not directly connected to the adjustment bottom plate 22, but a certain distance is left between the arc surface 2111 and the adjustment bottom plate 22, and the arc surface 2111 is connected to the adjustment bottom plate 22 through a plane perpendicular to the adjustment bottom plate 22. As long as the first protrusion 211 can be lifted up, it will be fine.

[0053] In some other embodiments, the lifting portion 433 is not provided with an outer convex structure, and its outer side surface is flush with the outer side surfaces of other parts of the adjustment rod 43, as long as the first protrusion 211 can be lifted up.

[0054] In some specific embodiments, reference Figure 4 and Figure 6 The adjustment seat 2 includes an adjustment base plate 22 and a fan mounting ring 23. The fan mounting ring 23 is arranged on a side of the adjustment base plate 22 away from the mounting plate 1. A first annular mounting groove 231 is arranged on the outer side of the fan mounting ring 23. The fan body 3 includes an adjustment connecting ring 34. A second annular mounting groove 341 is arranged on the inner side of the adjustment connecting ring 34. The positions of the first annular mounting groove 231 and the second annular mounting groove 341 correspond to each other. The fan structure 10 also includes a first ball assembly 25. The first ball assembly 25 includes a plurality of first balls 251. The plurality of first balls 251 are arranged in sequence around the axis of the fan mounting ring 23 and are arranged in the first annular mounting groove 231 and the second annular mounting groove 341, so that the fan body 3 can rotate relative to the adjustment seat 2.

[0055] By installing a plurality of first balls 251 in the first annular mounting groove 231 and the second annular mounting groove 341, a structure similar to a "ball bearing" is formed, so that the fan body 3 can rotate relative to the adjustment seat 2. In addition, the first balls 251 are simultaneously clamped in the first annular mounting groove 231 and the second annular mounting groove 341, which can limit the fan body 3 from moving away from the adjustment seat 2 along the axial direction of the adjustment base plate 22. Even if the adjustment seat 2 is at different tilt angles, the fan body 3 is stably connected to the adjustment seat 2 and can rotate relative to the adjustment seat 2.

[0056] In some specific embodiments, reference Figure 4 and Figure 6 A third mounting annular groove is provided on the side of the fan mounting ring 23 away from the adjusting base plate 22, and a fourth mounting annular groove corresponding to the position of the third mounting annular groove is provided on the fan body 3. The fan structure 10 also includes a second ball assembly 26, and the second ball assembly 26 includes a plurality of second balls 261. The plurality of second balls 261 are arranged in sequence around the axis of the fan mounting ring 23 and are arranged in the third mounting annular groove and the fourth mounting annular groove.

[0057] Specifically, the fan body 3 includes a fan main board 31 and an adjustment connecting ring 34, and the adjustment connecting ring 34 is arranged on the side of the fan main board 31 close to the adjustment base plate 22. The fourth mounting annular groove in this embodiment is arranged on the side of the fan main board 31 close to the adjustment base plate 22. When the adjustment seat 2 is tilted relative to the mounting plate 1, the side of the fan mounting ring 23 close to the fan main board 31 may directly contact the fan main board 31, so that the friction between the fan body 3 and the adjustment seat 2 increases, affecting the rotation of the fan body 3 relative to the adjustment seat 2. Therefore, a third mounting annular groove is provided on the side of the fan mounting ring 23 away from the adjustment base plate 22, and a fourth mounting annular groove is provided on the side of the fan main board 31 close to the adjustment base plate 22. The second ball bearing 261 is arranged in the third mounting annular groove and the fourth mounting annular groove. The second ball bearing 261 can separate the fan main board 31 and the fan mounting ring 23, and can also make the rotation of the fan body 3 relative to the adjustment seat 2 not affected, thereby ensuring the normal operation of the fan structure 10.

[0058] Furthermore, the fan main plate 31 is annular, and a fan center plate 32 is provided at the inner middle position of the fan straight plate, and a plurality of fan rods 33 are arranged in sequence around the fan center plate 32, one end of the fan rod 33 is connected to the fan main plate 31, and the other end is connected to the fan center plate 32. When the fan body 3 rotates, the plurality of fan rods 33 can generate wind force.

[0059] This embodiment also discloses a bathroom heater, referring to Figures 9 to 12 , including a shell 5 and a heating device, the heating device includes an air outlet net 7, a heating module 6 and the above-mentioned fan structure 10 with adjustable wind direction, the air outlet net 7 is arranged on the shell 5, the fan structure 10 and the heating module 6 are arranged on the inner side of the shell 5, and the fan structure 10, the heating module 6 and the air outlet net 7 are arranged in sequence.

[0060] The above-mentioned fan structure 10 is applied to the bathroom heater. Different from the structure in the background art in which a guide plate is provided at the air outlet, the fan structure 10 in this embodiment is provided as a whole on the back of the heating module 6. The direction of the hot air blown out by the bathroom heater can be controlled by adjusting the tilt direction of the fan body 3. Since the fan structure 10 is provided as a whole on the back of the heating module 6, it is not easily affected by the high temperature of the heating module 6 during use and is not easily damaged. Therefore, the fan structure 10 with adjustable wind direction used for the bathroom heater in the utility model has a longer service life, which is beneficial to optimizing the user experience and also beneficial to reducing the use cost.

[0061] Specifically, the bottom of the housing 5 serves as the mounting plate 1 in the fan structure 10 , and the adjustment seat 2 is disposed at the bottom of the housing 5 .

[0062] Furthermore, a blower 9 is provided inside the shell 5 .

[0063] In some specific embodiments, reference Figures 9 to 12The bathroom heater also includes a panel light 8, which can be slidably arranged on a side of the shell 5 close to the air outlet net 7, and the panel light 8 can cover or expose the air outlet net 7.

[0064] Specifically, the housing 5 includes a bottom shell 51 and a cover plate 52 , the air outlet net 7 and the panel light 8 are arranged on the cover plate 52 , and the fan structure 10 and the heating module 6 are arranged in the inner cavity of the bottom shell 51 .

[0065] refer to Fig.11 When the heating device is not working, the edges of the panel light 8 are basically aligned with the corresponding edges of the shell 5 and have corresponding sizes. The panel light 8 does not protrude or does not obviously protrude from the shell 5 and blocks the air outlet net 7.

[0066] refer to Fig.12 When the heating device is working, the panel light 8 slides on the shell 5, protrudes from the shell 5, and completely exposes the air outlet net 7.

[0067] When the bathroom heater is in a dormant state, the panel light 8 blocks the air outlet net 7, so that the overall space occupied by the bathroom heater is smaller, which is convenient for transportation and installation, and at the same time makes the luminous area of ​​the panel light 8 arranged on the shell 5 larger; when the heating device is in a working state, the panel light 8 exposes the air outlet net 7, and the hot air blown out by the heating device will not blow directly to the panel light 8, which is beneficial to reduce or avoid the negative impact of high temperature on the panel light 8 and extend the service life of the panel light 8.
