[0002] Heating equipment, such as bathroom heaters, is a common type of indoor heating appliance. Heating equipment typically consists of a main unit and a PTC (Positive Temperature Coefficient) heating element used to heat the air. Indoor air enters through the air inlet on the main unit, is heated by the PTC heating element, and is then exhausted into the room through the air outlet on the main unit, thus achieving indoor heating.

[0003] Because the exhaust vents on the main body of heating equipment are usually rectangular in shape, their appearance is not aesthetically pleasing. Therefore, a ring-shaped PTC heating element has appeared on the market, allowing the exhaust vent to be designed in a corresponding ring shape, thus improving its appearance.

[0004] However, the circular PTC heating element is difficult to manufacture, resulting in higher production costs. Utility Model Content

Furthermore, the non-closed heating structure has a more flexible shape, thus widely adaptable to different shaped exterior panels, making its application more extensive and its applicability stronger.

[0044] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the solutions of the embodiments of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of the embodiments of the present invention, but the embodiments of the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0046] To improve the aesthetics of the exhaust vents on the exterior panel of heating equipment, the exhaust vents are usually designed in a circular shape. Therefore, the PTC heating element corresponding to the exhaust vent is usually also set in a circular shape. However, the circular PTC heating element is more difficult to process, resulting in higher production costs.

[0047] Therefore, referring to Figure 1 and Figure 2 As shown, this embodiment provides a heating structure 100, including at least two heating elements 101 for heating air.

[0048] At least two heating elements 101 are arranged sequentially around a central point, and all heating elements 101 together form a non-closed structure with a notch 103.

[0049] In practice, at least two heating elements 101 can be arranged sequentially around a virtual center point, meaning that all heating elements 101 can be equidistant from the center point, and all heating elements 101 can eventually enclose a non-closed structure.

[0050] Since the heating structure 100 in this embodiment uses at least two heating elements 101, that is, it adopts a segmented structure, the heating structure 100 in this embodiment can reduce the manufacturing difficulty to a certain extent compared with the heating structure 100 with an integral structure, thereby achieving the purpose of reducing production costs.

[0051] It should be noted that the non-closed structure here refers to a structure of any shape that is not closed, such as a ring with a gap, a polygon with a gap, or an ellipse with a gap, etc. The specific design can be determined according to the appearance requirements of the corresponding application device.

[0052] For example, heating elements 101 can be configured as two, three, or as follows: Figure 1 and Figure 2The seven shown. For example, when the heating element 101 is configured as follows: Figure 1 and Figure 2 When the seven heating elements 101 are arranged as shown, they can form a shape like... Figure 1 and Figure 2 The diagram shows a non-closed heptagonal structure. Alternatively, in other examples, when there are a sufficient number of heating elements 101, all the heating elements 101 can be enclosed to form an approximately ring-shaped non-closed structure.

[0053] As can be seen from the above, the heating structure 100 of this embodiment is configured to include at least two heating elements 101 for heating air. The at least two heating elements 101 are sequentially arranged around a central point, and all heating elements 101 together form a non-closed structure with a notch 103. That is, by setting the heating structure 100 as a segmented structure rather than a closed integral structure, the segmented heating structure 100 is easier to manufacture than a closed integral structure. Therefore, the structural design of the heating structure 100 in this embodiment can reduce manufacturing difficulty to a certain extent, thereby reducing production costs. Furthermore, the non-closed heating structure 100 has a more flexible shape, thus it can be widely adapted to different shaped exterior panels, making its application more extensive and its applicability stronger.

[0054] Reference Figure 1 and Figure 2 As shown, in some embodiments, all heating elements 101 are enclosed to form a fan-ring structure or a non-closed polygonal structure 102, which not only makes the structure easier to manufacture to reduce production costs, but also can be adapted to an appearance panel with a circular or annular exhaust port to meet user needs and effectively improve its versatility.

[0055] For example, all the heating elements 101 in this embodiment can be arranged to form such that... Figure 1 and Figure 2 The non-closed heptagonal structure shown is adapted to fit the appearance panel with a circular or annular exhaust vent. Alternatively, in other examples, a sufficient number of heating elements 101 can be provided so that all heating elements 101 together form a fan-shaped ring structure, such as a half-ring or three-quarter ring structure. The specific structural shape can be set according to actual needs.

[0056] In some embodiments, at least any two adjacent heating elements 101 are connected in series or in parallel.

[0057] For example, when there are more than two heating elements 101, any two heating elements 101 can be connected in series or in parallel. Alternatively, when there are two heating elements 101, these two heating elements 101 can be connected in series or in parallel to meet different heating effects. In addition, when there are more than two heating elements 101, all heating elements 101 can be connected end to end in series to meet the needs of scenarios with higher heating efficiency.

[0058] For example, the heating element 101 in this embodiment can be a PTC heater, which has the advantages of rapid heating, no open flame, and long service life. Alternatively, in other examples, the heating element 101 can also be a resistance heating wire.

[0059] Reference Figures 3 to 5 As shown, this embodiment also provides a heating assembly 200, including a mounting bracket 201 and the heating structure 100 described above.

[0060] The specific structure and implementation principle of the heating structure 100 in this embodiment are the same as those of the heating structure 100 described above, and can bring the same or similar technical effects. They will not be described in detail here, but can be referred to the above description.

[0061] Specifically, refer to Figure 3 As shown, a first cavity 202 is formed on the mounting bracket 201. The top of the first cavity 202 has an opening and a ventilation hole structure is provided on the bottom wall of the first cavity 202. The first cavity 202 is arranged around a center point and encloses to form a non-closed structure. All heating elements 101 are housed in the first cavity 202.

[0062] In a specific implementation, the first cavity 202 can be enclosed to form a fan-shaped ring or a polygonal shape. At this time, the two ends of the first cavity 202 are separated and not connected, thus forming a non-closed structure that matches the shape of the heating structure 100, so as to better accommodate the heating structure 100.

[0063] In some embodiments, refer to Figure 3 As shown, at least two sub-chambers 203 are formed in the first cavity 202. The at least two sub-chambers 203 are arranged sequentially along the circumference of the mounting bracket 201 and enclosed to form a non-closed structure. Each sub-chamber 203 contains at least one heating element 101.

[0064] In other words, by forming at least two sub-chambers 203 within the inner cavity of the mounting bracket 201, and by sequentially arranging and enclosing multiple sub-chambers 203 along the circumference of the mounting bracket 201 to form a non-closed structure, different heating elements 101 can be housed within different sub-chambers 203, ensuring that all heating elements 101 ultimately present a non-closed structure. Thus, the mounting bracket 201 can function as a support or accommodator for the heating elements 101. Furthermore, because the mounting bracket 201 contains sub-chambers 203 arranged sequentially along its circumference in a non-closed structure, the heating elements 101 housed within it can be ultimately constrained as follows: Figure 4 The non-closed structure shown.

[0065] For example, the mounting bracket 201 in this embodiment can be made of alloy or metal to provide sufficient structural strength and a long service life. Alternatively, to save costs and reduce overall weight, the mounting bracket 201 can be made of heat-resistant plastic.

[0066] Furthermore, it should be noted that the center point in the arrangement of the heating elements 101 around a central point can be considered as the center point of the mounting bracket 201 in this embodiment.

[0067] Reference Figure 3 and Figure 4 As shown, in some embodiments, all sub-chambers 203 are arc-shaped structures extending circumferentially along the mounting bracket 201, and all sub-chambers 203 together enclose a fan-shaped ring structure.

[0068] In other words, all the sub-chambers 203 are arc-shaped chambers. Therefore, the enclosed structure formed by all the sub-chambers 203 is a fan-ring structure. This fan-ring structure can be used to house the heating structure 100, which has a non-closed structure, and the overall appearance is smooth.

[0069] In some embodiments, the outer contour shape of the heating element 101 is adapted to the inner cavity shape of the corresponding sub-chamber 203, thereby making the fit between the heating element 101 and the sub-chamber 203 better.

[0070] Reference Figure 3 and Figure 4 As shown, in some embodiments, a second cavity 204 is also formed on the mounting bracket 201. The second cavity 204 is disposed between the first and last ends of the first cavity 202 and closes the first and last ends of the first cavity 202, thereby allowing the first cavity 202 to form a non-closed structure, so that its shape design is more flexible.

[0071] As can be seen from the above, the first cavity 202 on the mounting bracket 201 divides all the sub-cavities 203 to form a fan-shaped ring structure. The sub-cavities 203 are used to house the heating element 101, while the remaining part of the inner cavity of the mounting bracket 201 can be formed as the second cavity 204. The first cavity 202 and the second cavity 204 together form the complete inner cavity of the mounting bracket 201, that is, a closed ring structure.

[0072] In other words, in order to facilitate the manufacture of the mounting bracket 201, a closed and complete inner cavity is formed on the mounting bracket 201. However, a part of the inner cavity of the mounting bracket 201 forms a first cavity 202 for accommodating the heating element 101, while the remaining part forms a second cavity 204 for not accommodating the heating element 101.

[0073] Reference Figure 3 As shown, in some embodiments, the annular structure and the fan-shaped structure are arranged concentrically, thereby making the final heating assembly 200 more regular in structure and better in appearance.

[0074] Reference Figure 4 As shown, in some embodiments, all sub-chambers 203 have the same dimensions along the circumference of the mounting bracket 201, that is, all sub-chambers 203 have the same arc length along their circumference, which means that all sub-chambers 203 have the same specifications, thereby making it easier to manufacture and form the sub-chambers 203, and can be adapted to heating elements 101 of the same specifications, so as to improve the efficiency of the placement operation of heating elements 101 in the sub-chambers 203.

[0075] In some embodiments, refer to Figure 3 As shown, at least one of the sub-cavities 203 has the same circumferential dimension along the mounting bracket 201 as the second cavity 204, meaning that at least one sub-cavity 203 has the same specifications as the second cavity 204, thus simplifying the manufacturing process. When all sub-cavities 203 also have the same specifications, then all sub-cavities 203 and the second cavity 204 have the same specifications, effectively simplifying the manufacturing process and making the internal structure of the entire mounting bracket 201 more regular and aesthetically pleasing.

[0076] For example, in this embodiment, the mounting bracket 201 is annular, meaning that the outer contour of the mounting bracket 201 matches the shape of its inner cavity, making the overall structure of the mounting bracket 201 more concise and aesthetically pleasing. Of course, in other embodiments, the mounting bracket 201 can also be rectangular, and an annular inner cavity can be formed within the rectangular mounting bracket 201 to satisfy the above structural design.

[0077] Reference Figure 3As shown, in some embodiments, at least one first partition structure 205 is provided in the first cavity 202, the first partition structure 205 being used to divide the first cavity 202 into at least two sub-cavities 203.

[0078] Specifically, the first partition structure 205 can be a first partition plate, which can extend along the axial direction of the mounting bracket 201 and be integrally formed with the mounting bracket 201 to simplify the manufacturing process and improve the overall structural strength of the mounting bracket 201.

[0079] Reference Figure 3 As shown, a second partition structure 207 is provided in the inner cavity of the mounting bracket 201. The second partition structure 207 is used to divide the inner cavity of the mounting bracket 201 into a first cavity 202 and a second cavity 204.

[0080] Specifically, the second partition structure 207 can be a second partition plate, which can extend along the axial direction of the mounting bracket 201 and be integrally formed with the mounting bracket 201 to simplify the manufacturing process and improve the overall structural strength of the mounting bracket 201.

[0081] In some embodiments, a reinforcing structure 206 may be provided on the inner wall of the first cavity 202, such as reinforcing ribs or reinforcing blocks, to effectively enhance the structural strength of the mounting bracket 201.

[0082] In some embodiments, the heating assembly 200 further includes a cover that covers the second cavity 204 to seal the second cavity 204. That is, the second cavity 204 is not used to house the heating element 101. In order to avoid the waste of air by allowing air to enter the second cavity 204 and thus preventing it from entering the first cavity 202 and being heated by the heating element 101, the cover can be provided to seal the second cavity 204.

[0083] For example, the cover can be a cover plate, which can be snapped or screwed onto the mounting bracket 201.

[0084] For example, the cover can be made of alloy or plastic.

[0085] Reference Figures 6 to 9 As shown, this embodiment also provides a heating module 300, including a fan housing 301, an air outlet 302, and a heating component 200 as described above.

[0086] The specific structure and implementation principle of the heating component 200 in this embodiment are the same as those of the heating component 200 described above, and can bring the same or similar technical effects. They will not be described in detail here. For details, please refer to the description of Embodiment 1.

[0087] Specifically, refer to Figure 7 As shown, the air outlet 302 of the heating module 300 in this embodiment is provided with an air outlet 303. Specifically, the air outlet 302 may be provided with a grid structure, and a plurality of grid holes on the grid structure are formed as air outlets 303.

[0088] The air casing 301 and the air outlet 302 are located on both sides of the heating assembly 200 and are respectively connected to the mounting bracket 201 of the heating assembly 200. The air casing 301 has an air cavity 304 and an air inlet 305 communicating with the air cavity 304. All sub-chambers 203 are respectively connected to the air cavity 304 and the air outlet 303.

[0089] Specifically, indoor air can enter the air cavity 304 of the air shell 301 through the air inlet 305 of the air shell 301, and then enter the sub-cavity 203 through the ventilation hole structure on the first cavity 202. After being heated by the heating element 101, the air is discharged into the room through the top opening of the first cavity 202 and the air outlet 303 on the air outlet 302, thereby realizing indoor heating operation.

[0090] In some embodiments, the second cavity 204 of the heating assembly 200 is located at the air inlet 305.

[0091] Specifically, it can be combined with Figure 10 As shown, when the heating module 300 of this embodiment is applied to a heating device using a centrifugal fan, the air duct of the centrifugal fan is driven by the centrifugal fan to take in air from the axial direction of the centrifugal impeller and then to the radial direction away from the centrifugal impeller. The air coming out of the centrifugal impeller will be phased (i.e., the air direction will be phased by 90° and then become parallel to the direction of air intake) after entering the air cavity 304 of the air casing 301 before it can be blown into the room through the air outlet 303 on the air outlet 302. Based on this characteristic, the airflow is usually greatest in the air cavity 304 and near the air outlet 302, while the airflow is smaller near the air inlet 305 of the air casing 301. Therefore, the second cavity 204 without the heating element 101 is positioned at the air inlet 305, so that the sub-cavity 203 with the heating element 101 is relatively far away from the air inlet 305 of the air casing 301. This allows a large amount of air to enter the sub-cavity 203 to provide air cooling for the heating element 101 in the sub-cavity 203, thereby improving the local heat dissipation effect of the heating element 101 in the sub-cavity 203 and preventing the heating element 101 from overheating and causing damage.

[0092] Furthermore, it should be noted that when the second cavity 204 is closed, the air in the air chamber 304 cannot enter the second cavity 204 and instead enters the first cavity 202. The second cavity 204 can also guide the airflow, thereby achieving efficient utilization of the air entering the air chamber 304. This allows the air entering the air chamber 304 to be heated by the heating element 101 in the first cavity 202 and then discharged into the room, thereby improving heating efficiency. It also allows all the air to enter the sub-cavity 203 to achieve greater localized air cooling of the heating element 101.

[0093] It should be noted that all the chamber walls of the sub-chambers 203 are provided with ventilation holes that communicate with the air chambers 304, so that the sub-chambers 203 and the air chambers 304 can be connected through the ventilation holes, so that the air in the air chambers 304 can enter the sub-chambers 203 and be heated by the heating element 101.

[0094] For example, the ventilation hole structure can be configured to include multiple air inlets to achieve efficient air intake.

[0095] For example, the outer contour shape of the air outlet 303 is adapted to the outer contour shape of the heating structure 100, thereby making the appearance of the heating structure 100 better compatible with the appearance of the air outlet 303.

[0096] For example, when the heating structure 100 is in the form of a fan ring structure, the air outlet 303 can also be in the form of a fan ring structure.

[0097] Reference Figures 10 to 11 As shown, this embodiment also provides a heating device 400, including a device housing 411, a centrifugal fan 404, a centrifugal impeller 405, and a heating module 300.

[0098] The specific structure and implementation principle of the heating module 300 in this embodiment are the same as those of the heating module 300 provided above, and can bring the same or similar technical effects. They will not be described in detail here, but can be referred to the above description.

[0099] For example, the heating device 400 in this embodiment can be a bathroom heater or an air conditioner.

[0100] Specifically, the equipment housing 411 is provided with an air inlet 412 and an air outlet 413. The centrifugal fan 404, the centrifugal impeller 405 and the heating module 300 are all located in the equipment housing 411. The centrifugal fan 404 is connected to the air inlet 412, and the air outlet of the centrifugal fan 404 is connected to the air inlet 305 of the heating module 300. The air outlet 303 of the heating module 300 is connected to the air outlet 413.

[0101] Specifically, the equipment housing 411 may include a box body 401, a box cover 402, an exterior panel 406, a decorative panel 407, and a heater panel 409. The box cover 402 is snapped onto one side of the box body 401, the exterior panel 406 is snapped onto the side of the box cover 402 away from the box body 401, and the heater panel 409 is located between the box cover 402 and the exterior panel 406. The housing cover 402 is provided with a housing cover air inlet 403 and a through hole 416 that communicates with the air outlet 303 of the air outlet component 302. The housing cover air inlet 403 is connected to the centrifugal fan 404. The exterior panel 406 is provided with an exterior panel air inlet 408 that communicates with the housing cover air inlet 403. At this time, the exterior panel air inlet 408 and the housing cover air inlet 403 together form the air inlet 412 of the equipment housing 411. Then, the heater panel 409 is provided with a panel air outlet 410 that communicates with the through hole 416, and the exterior panel 406 is provided with an opening 415 that allows the heater panel 409 to be exposed. The through hole 416, the opening 415 and the panel air outlet 410 together form the exhaust port 413 of the equipment housing 411.

[0102] Reference Figure 10 As shown, the specific heating process is as follows: After the centrifugal fan 404 inside the housing 401 is powered on and starts rotating, it drives the centrifugal impeller 405 to rotate. Air enters from the air inlet 408 on the exterior panel 406, and then enters the centrifugal impeller 405 through the air inlet 403 on the housing cover 402. Since the first chamber 202 of the heating module 300 is located on the side of the second chamber 204 furthest from the centrifugal fan 404, the air passes through the centrifugal impeller 405 and exits from the centrifugal impeller 405. After being radially discharged, the air enters the air cavity 304. Here, the air is first guided by the shell wall of the second cavity 204, then phase-shifted before entering the first cavity 202. After being heated by the heating structure 100, the heated air passes through the air outlet 303 of the air outlet component 302, and then through the through hole 416 on the housing cover 402, the panel air outlet 410 on the heater panel 409, and the opening 415 on the exterior panel 406, blowing the heated air into the room. The specific airflow direction can be referenced... Figure 10 As shown by the arrow in the image.

[0103] In addition, a decorative panel 407 can be provided at the opening 415 to cover the part of the air outlet 302 except for the air outlet 303 and the part of the heater panel 409 except for the panel air outlet 410, so as to achieve an aesthetic purpose.

[0104] Reference Figure 10 and Figure 11As shown, in some embodiments, the air outlet 302 of the heating module 300 is provided with a first snap-fit ​​portion 306, and the device housing 411 is provided with a second snap-fit ​​portion 414. The air outlet 302 is connected to the device housing 411 through the snap-fit ​​engagement of the first snap-fit ​​portion 306 and the second snap-fit ​​portion 414.

[0105] Specifically, the second snap-fit ​​part 414 can be provided on the heater panel 409 of the device housing 411.

[0106] For example, one of the first latching portion 306 and the second latching portion 414 can be a latching groove, and the other can be a latching protrusion. For instance, the first latching portion 306 can be a latching groove, and the second latching portion 414 can be a latching protrusion. Alternatively, the first latching portion 306 can be a latching protrusion, and the second latching portion 414 can be a latching groove.
