Description

Technical Field

[0001] The present disclosure relates to the technical field of household electrical appliances, and in particular to a bathroom heater. Background Art

[0002] Because of the advantages of air-heated bathroom heaters, such as no strong light, no open flame, safety and full-area heating, they have basically become the mainstream products in the bathroom heater industry. The current air intake method of air-heated bathroom heaters is mainly grille intake, or holes are opened around the light panel to let in air. The appearance is not neat enough. Some bathroom heaters set air intake plates at the air inlet of the panel to improve the overall appearance, but the air intake plates need to be suspended and protrude from the ceiling to achieve air intake. Although the appearance of the bathroom heater is relatively neat, the air intake plates protrude from the ceiling plane, which is relatively abrupt as a whole. Utility Model Content

[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0037] The following is a detailed description of the bathroom heater through specific embodiments:

[0038] Reference Figures 1 to 10 As shown, some embodiments of the present invention provide a bathroom heater, comprising a panel 1, an air inlet plate 2 and a drive assembly.

[0039] Among them, an air inlet is opened on the panel 1, and the air inlet plate 2 is arranged at the corresponding position of the air inlet; the driving assembly includes a driving motor 5, a gear 3 and a rack 4. The driving motor 5 is relatively fixed to the panel 1, and the gear 3 is connected to the driving motor 5. The position of the gear 3 relative to the panel 1 is relatively fixed, and the rack 4 is arranged on the air inlet plate 2 and extends along the axial direction of the air inlet. When the gear 3 is engaged with the rack 4, the driving motor 5 drives the gear 3 to rotate, which can drive the rack 4 to move linearly relative to the gear 3 and the panel 1, and then drive the air inlet plate 2 to move relative to the panel 1 along the axial direction of the air inlet to open or close the air inlet.

[0040] In specific implementation, a guide portion 42 is provided on the rack 4, and the guide portion 42 is extended along the extension direction of the rack 4. A guide limiter 11 is provided on the panel 1, and the guide limiter 11 slides with the guide portion 42 to guide and limit the movement of the rack 4. That is to say, the guide limiter 11 is provided on the panel 1. When the rack 4 moves, the guide portion 42 on the rack 4 can slide with the guide limiter 11 along the extension direction of the rack 4 (that is, the axial direction of the air inlet), thereby limiting the movement direction of the rack 4 and the air inlet plate 2. When the bathroom heater is turned on and running, the air inlet plate 2 moves away from the panel 1 and the air inlet along the axial direction of the air inlet, thereby opening the air inlet to realize the air intake of the bathroom heater. After the bathroom heater finishes working, the air inlet plate 2 moves close to the panel 1 and the air inlet along the axial direction of the air inlet until the air inlet can be covered to enhance the overall appearance of the bathroom heater.

[0041] It should be noted that the air inlet is a hole-like structure formed on the panel 1. The axial direction of the air inlet is the axial direction of the hole-like structure, that is, the thickness direction of the panel 1, or the direction perpendicular to the surface of the panel 1. Taking the installation of the bathroom heater on the ceiling as an example, the axial direction of the air inlet is the height direction of the bathroom heater. The air inlet plate 2 can move relative to the panel 1 along the axial direction of the air inlet, that is, the height direction of the bathroom heater, and thus can open the air inlet to allow air to enter the bathroom heater, and can also cover the air inlet to ensure a neat appearance.

[0042] Reference Figure 2 and Figure 3As shown, a motor mounting base 7 is provided on the panel 1, and the drive motor 5 can be connected to the motor mounting base 7 by fasteners such as screws, thereby mounting the drive motor 5 on the panel 1. Of course, the drive motor 5 can also be provided on other non-moving parts of the bathroom heater, for example, on the housing of the bathroom heater, etc. This disclosure does not limit this, as long as the drive motor 5 can be fixed relative to the panel 1 so that the rack 4 can move relative to the panel 1.

[0043] In a specific implementation, the output shaft 51 of the driving motor 5 is formed as a flat shaft, and a flat hole is opened on the gear 3. The flat hole matches the size of the flat shaft of the driving motor 5, so as to drive the gear 3 to rotate through the flat shaft.

[0044] In some embodiments, reference Figure 7 As shown, the rack 4 is provided with a guide hole 41, which extends along the extension direction of the rack 4 and is closed at both ends of the guide hole 41 along the extension direction. The guide stopper 11 is passed through the guide hole 41 and slides relative to the guide hole 41 along the extension direction of the guide hole 41. In other words, when the guide stopper 11 is passed through the guide hole 41, the inner wall of the guide hole 41 can limit the position of the guide stopper 11, and the closed ends of the guide hole 41 along the extension direction can limit the movement. In other words, the guide stopper 11 can slide between the two ends of the guide hole 41 relative to the guide portion 42 to limit the relative position between the air inlet plate 2 and the panel 1.

[0045] When implementing it, refer to Figure 1 and Figure 6 As shown, when the guide limiter 11 abuts against the hole wall at one end of the guide hole 41 along the extension direction, the air inlet plate 2 is flush with the panel 1 to cover the air inlet and enhance the overall appearance of the bathroom heater. When the guide limiter 11 abuts against the hole wall at the other end of the guide hole 41 along the extension direction, the air inlet plate 2 protrudes from the panel 1 along the axial direction of the air inlet, and an air inlet gap is formed between the air inlet plate 2 and the panel 1. The air inlet gap is connected to the air inlet to open the air inlet and allow air to enter the bathroom heater. At the same time, when the guide limiter 11 abuts against the hole wall at the other end of the guide hole 41 along the extension direction, it can also prevent the air inlet plate 2 from detaching from the panel 1, ensuring user safety.

[0046] Of course, it should be noted that the limitation between the guide limiter 11 and the guide portion 42 can also be achieved through other forms of structures, and the present disclosure does not limit this. It is sufficient as long as limiting ribs can be formed on both ends of the rack 4 along the axis of the air inlet to limit the movement of the rack 4 and the air inlet plate 2.

[0047] In some embodiments, reference Figure 8 and Figure 10As shown, the rack 4 is provided with a guide rib located on one side of the guide hole 41 along the extension direction. The guide limiter 11 is disposed around the periphery of the guide rib and slidably cooperates with the guide rib, and the guide rib forms a guide portion 42. It is understandable that the gear 3 and the guide limiter 11 are both disposed on the panel 1, and the gear 3 is located on the side of the guide portion 42 away from the guide limiter 11. The position of the rack 4 can be limited by the gear 3 and the guide limiter 11. The guide limiter 11 is disposed around the periphery of the guide portion 42, that is, the guide limiter 11 can limit the rack 4 from multiple directions, so that the rack 4 can move along the axial direction of the air inlet.

[0048] In specific implementation, the guide limit member 11 includes a first surround 111, a second surround 112 and a third surround 113 connected in sequence. The first surround 111, the second surround 112 and the third surround 113 jointly form a guide limit slot 115. The second surround 112 is passed through the guide hole 41 to cooperate with the guide rib. The guide rib is located in the guide limit slot 115 and slides with the guide limit slot 115.

[0049] For example, referring to Figure 10 As shown, the guide and limiting groove 115 is a concave groove, and the shape of the guide rib is adapted to the shape of the guide and limiting groove 115 to achieve a sliding fit between the guide rib and the guide and limiting groove 115. It is understood that the width of the guide hole 41 is greater than the width of the guide and limiting member 11 to facilitate installation. Through the arrangement of the guide and limiting member 11 and the gear 3, the fit between the guide and limiting groove 115 on the guide and limiting member 11 and the guide portion 42 can be ensured.

[0050] In a specific implementation, one side wall of the guide portion 42 (ie, the guide rib) is formed as the inner wall of the guide hole 41 , so that the guide limiter 11 can slide and cooperate with the guide portion 42 when passing through the guide hole 41 .

[0051] Furthermore, the stopper also includes a fixing block 114, to which at least one of the first peripheral edge 111, the second peripheral edge 112, and the third peripheral edge 113 is connected, and the fixing block 114 is fixedly connected to the panel 1. Specifically, the fixing block 114 can be installed on the panel 1 using fasteners such as screws to avoid opening holes in the first peripheral edge 111, the second peripheral edge 112, or the third peripheral edge 113 that affect sliding performance, thereby ensuring service life.

[0052] In some embodiments, reference Figure 9 As shown, the rack 4 includes a rack body 43 and a plurality of teeth 44 arranged on one side of the rack body 43. The rack body 43 extends along the axial direction of the air inlet, and the plurality of teeth 44 are arranged in sequence along the extension direction of the rack body 43, so that the rack 4 can move linearly along the axial direction of the air inlet under the drive of the gear 3.

[0053] In a specific implementation, the guide holes 41 are provided on the rack body 43 and arranged side by side with the plurality of teeth 44 to accommodate the actual installation space of the bathroom heater. Of course, it should be noted that the guide holes 41 and the teeth 44 can also be arranged in other ways, and this disclosure does not limit this, as long as the guide holes 41 and the teeth 44 can be arranged along the axis of the air inlet to accommodate the actual installation space of the bathroom heater.

[0054] Continue to refer to Figure 9 As shown, the rack 4 further includes a fixing base 45, to which the rack body 43 is connected, and the fixing base 45 is fixedly connected to the air inlet plate 2. Specifically, the fixing base 45 can be mounted on the air inlet plate 2 using fasteners such as screws. The fixing base 45 can also serve as a limiting structure for sliding between the guide limiter 11 and the guide portion 42 to limit the extreme position of the movement of the air inlet plate 2.

[0055] In some embodiments, reference Figures 2 to 6 As shown, the air inlet plate 2 is provided with a guide post 21, and the panel 1 is provided with a through hole 12 corresponding to the guide post 21. A shaft sleeve 6 is disposed within the through hole 12. The guide post 21 is inserted into the shaft sleeve 6 and slidably cooperates with the shaft sleeve 6 to follow the relative sliding between the guide portion 42 and the guide stop 11 to ensure smoother movement. Specifically, the shaft sleeve 6 is made of a wear-resistant and lubricating material such as POM or nylon to ensure longevity.

[0056] In some embodiments, reference Figure 6 As shown, the rack 4 is disposed at the center of the side of the air inlet plate 2 facing the air inlet. In a specific implementation, there are two guide posts 21, and the rack 4 is located on the midline of the line connecting the two guide posts 21. It will be appreciated that the rack 4 and the two guide posts 21 form a triangular support structure, making the structure more stable, thereby enabling smoother sliding and improving the stability of the air inlet plate 2.

[0057] Of course, it should be noted that the guide columns 21 can be single, three, four or more, and the present disclosure does not limit this, as long as they can be reasonably arranged on the air inlet plate 2 and can guide the air inlet plate 2 to move.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.

[0059] The above are merely specific embodiments of the present disclosure, intended to enable those skilled in the art to understand and implement the present disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure is not limited to these embodiments, but is to be construed in the broadest manner consistent with the principles and novel features disclosed herein.
