Description

Technical Field

[0001] This application relates to the field of bathroom heater technology, and more particularly to a bathroom heater. Background Technology

[0002] Most common bathroom heaters use a single-fan duct structure, where heating and ventilation are handled by the same fan. During use, a stepper motor switches the duct. Because the duct switching structure requires a certain amount of duct space, a long duct needs to be constructed to house the switching components. However, this long duct design increases duct resistance, reduces the airflow for both heating and ventilation, and the single-fan structure cannot achieve simultaneous heating and ventilation.

[0003] To address the aforementioned technical issues, the improved bathroom heater adopts a dual-fan air duct scheme, with one fan responsible for heating and the other for ventilation, eliminating the air duct switching structure. However, in this dual-fan structure, the two fans cannot ventilate or heat simultaneously, thus failing to maximize the performance of the bathroom heater.

[0004] Therefore, there is an urgent need for a bathroom heater with a dual-fan structure that can simultaneously perform ventilation and heating to maximize the performance of the fans. Utility Model Content

[0005] This application provides a bathroom heater that can simultaneously ventilate and heat through two fans. Compared with the traditional single-fan or dual-fan structure, it increases the air volume for ventilation and heating, reduces noise, and maximizes the performance of the fans.

[0006] The bathroom heater provided in this application includes: a heating component, the heating component including a first air outlet; at least two fan components, wherein each fan component includes: a first housing, the first housing including a first air cavity, the first air cavity including an air inlet and a second air outlet; a fan, the fan being configured to draw air into the first air cavity from the air inlet; and a flow guiding component, the flow guiding component being configured to selectively switch operating modes; wherein, when the flow guiding component is switched to the first operating mode, the flow guiding component is configured to guide the air drawn into the first air cavity to the second air outlet and blow it out; when the flow guiding component is switched to the second operating mode, the flow guiding component is configured to guide the air drawn into the first air cavity to the heating component, so that the air is heated by the heating component and then blown out from the first air outlet.

[0007] In some feasible implementations, the heating assembly includes a second housing and a heating element; the second housing includes a second air cavity, the second air cavity includes a first air outlet, and the second air cavity is configured to selectively communicate with or be isolated from the first air cavity; the heating element is disposed at the first air outlet.

[0008] In some feasible implementations, the flow guiding component includes a damper rotatably disposed within a first air cavity; when the damper is configured to rotate to a first position, it isolates the first air cavity and the second air cavity and opens a second air outlet, thereby switching the flow guiding component to a first operating mode; when the damper is configured to rotate to a second position, it connects the first air cavity and the second air cavity and closes the second air outlet, thereby switching the flow guiding component to a second operating mode.

[0009] In some feasible implementations, the flow guiding component also includes a drive element; the drive element is connected to the damper drive and is configured to drive the damper to rotate.

[0010] In some feasible implementations, the first housing includes a volute, which includes a first air cavity; the second air outlet and the damper are both located on the air outlet side of the volute, and the air inlet is opened in the axial direction of the volute.

[0011] In some feasible implementations, the first housing and the second housing are stacked along the axial direction of the volute, and the air inlet is located between the fan assembly and the heating assembly.

[0012] In some feasible implementations, the bathroom heater also includes: a cover plate and a body, the cover plate and the body forming an installation cavity, at least two fan assemblies being disposed within the installation cavity; a heating assembly being located outside the installation cavity; an air inlet being opened on the cover plate, and a second air outlet being opened on the body.

[0013] In some feasible implementations, the first air cavity further includes a first air guide port, and the second air cavity further includes a second air guide port, with the first air guide port and the second air guide port corresponding in position; the damper is configured to close the first air guide port and the second air guide port when rotated to the first position to isolate the first air cavity and the second air cavity; the damper is configured to open the first air guide port and the second air guide port when rotated to the second position to connect the first air cavity and the second air cavity.

[0014] In some feasible implementations, the first air vent is opened on the cover plate, and at least one first air vent is offset along the length of the bathroom heater.

[0015] In some feasible implementations, the bathroom heater also includes: at least two air guides, which are respectively set in at least two first air chambers; wherein, the air damper is located between the air guide and the second air outlet, and when the air damper is configured to rotate to the second position, the air in the first air chamber passes through the air guide and the second air outlet in sequence and then enters the second air chamber.

[0016] The bathroom heater provided in this application embodiment can provide power for ventilation and heating simultaneously through two fans, maximizing the performance of the fans. Compared with the traditional single or dual fan structure, it can effectively increase the air volume and achieve the same air volume as the traditional single fan with a lower speed. Thus, under the same air volume condition, the wind noise can be reduced by reducing the speed, thereby improving the product's market competitiveness. Attached Figure Description

It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0036] Figure 1 This is a schematic diagram of the structure of a bathroom heater provided in an embodiment of this application; Figure 2 This is an exploded view of a bathroom heater provided in an embodiment of this application.

[0037] See Figure 1 and Figure 2 As shown, the bathroom heater provided in this application embodiment includes a heating component 10, at least two fan components 20, and a flow guiding component 30.

[0038] The heating assembly 10 includes a first air outlet 101. The heating assembly 10 is used to heat air, and the first air outlet 101 is used to discharge the heated air. Figure 1The number of first air outlets 101 shown is multiple. In other implementations, the number of first air outlets 101 can also be one, with one first air outlet 101 opening along the length of the heating component 10. It can be understood that when there is only one first air outlet 101, the first air outlet 101 is a continuous air outlet, and when there are multiple first air outlets 101, the multiple first air outlets 101 are arranged sequentially along the length of the heating component 10.

[0039] Each fan assembly 20 includes a first housing 201 and a fan 202.

[0040] The first housing 201 includes a first air cavity 201a, which includes an air inlet a1 and a second air outlet a2. The air inlet a1 is used to introduce air from outside the first air cavity 201a into the first air cavity 201a, and the second air outlet a2 is used to exhaust air from the first air cavity 201a to the external environment. That is, air can enter the first air cavity 201a through the air inlet a1 and exit the second air cavity 102a through the second air outlet a2. Specifically, at least two fan assemblies 20 include at least two first housings 201, and the at least two first housings 201 can be arranged along the length of the bathroom heater. For example, when there are two fan assemblies 20, the two first housings 201 are arranged side-by-side along the length of the bathroom heater; or, when there are three fan assemblies 20, the three first housings 201 are arranged sequentially along the length of the bathroom heater.

[0041] The first housing 201 can be an independent housing structure with an air inlet a1 and a second air outlet a2, or, as... Figure 2 As shown, the bathroom heater may also include an outer shell, with at least two first shells 201 disposed within the outer shell, thereby improving the overall aesthetics of the bathroom heater.

[0042] The fan 202 is rotatably disposed within the first air chamber 201a, and the introduction and exhaust of air within the first air chamber 201a are achieved through the fan 202. Specifically, during the rotation of the fan 202, air from the external environment can be drawn into the first air chamber 201a through the air inlet a1.

[0043] The airflow guiding component 30 is disposed within the first air cavity 201a. The airflow guiding component 30 includes a first operating mode and a second operating mode, and the airflow guiding component 30 can be selectively switched between the first operating mode and the second operating mode.

[0044] When the airflow guiding component 30 switches to the first operating mode, it guides the air drawn into the first air chamber 201a to the second air outlet a2 for expulsion. In this operating mode, the air drawn in by the fan 202 is guided by the airflow guiding component 30 to the second air outlet a2. That is, the air drawn into the first air chamber 201a is directly discharged to the external environment without being heated; in this operating mode, the bathroom heater is in ventilation mode. During ventilation, the bathroom heater can guide the poor-quality indoor air to the external environment through the second air outlet a2. The external environment can refer to the outdoors.

[0045] When the airflow guiding component 30 switches to the second operating mode, it guides the air drawn into the first air chamber 201a to the heating component 10, where it is heated and then blown out from the first air outlet 101. In this operating mode, the air drawn in by the fan 202 does not pass through the second air outlet a2, but is instead guided by the airflow guiding component 30 into the heating component 10 for heating. In this operating mode, the bathroom heater is in hot air mode. During hot air operation, the bathroom heater can draw in indoor air, heat it, and then return it to the room to raise the indoor temperature.

[0046] Specifically, the airflow guiding component 30 can be slidably disposed within the first air cavity 201a, or it can be rotatably disposed within the first air cavity 201a. For example, when the airflow guiding component 30 is slidably disposed within the first air cavity 201a, the airflow direction can be changed by sliding when guiding air. Alternatively, when the airflow guiding component 30 is rotatably disposed within the first air cavity 201a, the airflow direction can be changed by rotating when guiding air. Of course, the airflow guiding component 30 can also be installed in other ways besides sliding and rotating.

[0047] It should be emphasized that the airflow guiding components 30 and fans 202 provided in this application embodiment can be configured in a one-to-one correspondence. That is, there are at least two fans 202 and at least two airflow guiding components 30. Thus, the operating modes of at least two airflow guiding components 30 can include a first operating mode and / or a second operating mode. For example, when there are two fans 202 and two airflow guiding components 30, and both airflow guiding components 30 are in the first operating mode, the air in both first air chambers 201a is ventilated to the external environment, and the bathroom heater is in ventilation mode. Alternatively, both airflow guiding components 30 are in the second operating mode, and the air in both first air chambers 201a is ventilated to the heating component 10 and then discharged after heating, and the bathroom heater is in hot air mode. Alternatively, one of the two airflow guiding components 30 is in the first operating mode and the other is in the second operating mode, so that the bathroom heater can be in both ventilation and hot air modes simultaneously.

[0048] The bathroom heater provided in this embodiment can simultaneously provide power for ventilation and heating using at least two fans 202, maximizing its performance. Compared to traditional single-fan or dual-fan structures, it effectively increases airflow and achieves the same airflow as a traditional single-fan unit with a lower rotation speed. Furthermore, while maintaining the same airflow, it reduces noise by lowering the rotation speed, enhancing the product's market competitiveness. Simultaneously, the airflow guide component 30 allows the bathroom heater to operate in both ventilation and heating modes simultaneously, fulfilling its multi-functional requirements.

[0049] It should be emphasized that this application Figure 2 The diagram shows the installation of two fans 202. In other feasible implementations, the number of fans 202 can also be 3, 4, or 6. When there are three fans 202, the number of the first air chamber 201a, the air guide assembly 30, the air inlet a1, and the second air outlet a2 are all three. The three fans 202 can be arranged sequentially along the length of the bathroom heater. It can be understood that the number of fans 202 can be positively correlated with the length of the bathroom heater. For example, the more fans 202, the longer the bathroom heater; the fewer fans 202, the shorter the bathroom heater. A relatively long bathroom heater can be adapted to a larger space; a relatively short bathroom heater can be adapted to a smaller space.

[0050] See also Figure 2 In one specific implementation, the heating assembly 10 includes a second housing 102 and a heating element 103.

[0051] The second housing 102 includes a second air cavity 102a, which can be understood as a heating air cavity. The second air cavity 102a includes a first air outlet 101, and the second air cavity 102a is used to selectively connect with or disconnect from the first air cavity 201a.

[0052] Specifically, in the first operating mode of the airflow guiding component 30, the first air chamber 201a and the second air chamber 102a are isolated. The air drawn into the first air chamber 201a cannot enter the second air chamber 102a for heating, but is instead discharged through the second air outlet a2, enabling the bathroom heater to achieve ventilation mode. In the second operating mode of the airflow guiding component 30, the first air chamber 201a and the second air chamber 102a are connected. The air drawn into the first air chamber 201a is guided by the airflow guiding component 30 to the second air chamber 102a, and the heating element 103 is located at the first air outlet 101. That is to say, the air is heated by the heating element 103 before being discharged from the second air chamber 102a, so that the air discharged from the first air outlet 101 is hot air, making the bathroom heater a hot air state.

[0053] In this way, the second air chamber 102a in the heating component 10 and the first air chamber 201a in the fan assembly 20 are two independent air chambers, so that the ventilation state and the hot air state of the bathroom heater are realized in two independent air chambers, and there is no interference between them. That is to say, when the bathroom heater is in the ventilation state and the hot air state, the air will not interfere during the circulation process, which can effectively reduce the wind noise of the bathroom heater during operation.

[0054] Figure 3 This is a partial exploded view of a bathroom heater provided in an embodiment of this application.

[0055] In a specific implementation, see Figure 3 As shown, the flow guiding assembly 30 includes a damper 301, which is rotatably disposed within the first air chamber 201a.

[0056] Specifically, during the rotation of the damper 301, the damper 301 is in different positions in the first air chamber 201a. When the damper 301 rotates to the first position, it can open the second air outlet a2 and disconnect the first air chamber 201a and the second air chamber 102a, and the air guiding component 30 switches to the first working mode. At this time, the air in the first air chamber 201a cannot be guided to the second air chamber 102a, but is guided to the external environment through the second air outlet a2 to realize the ventilation operation of the bathroom heater. In this implementation, the damper 301 can rotate to the first position along the first direction, which can be understood as the connection position between the first air chamber 201a and the second air chamber 102a. The specific way to isolate the first air cavity 201a and the second air cavity 102a can be that the damper 301 can block the connection between the first air cavity 201a and the second air cavity 102a at the first position, or the damper 301 can cover the connection between the first air cavity 201a and the second air cavity 102a at the first position, so that the first air cavity 201a and the second air cavity 102a are not connected.

[0057] When the damper 301 rotates to the second position, it can close the second air outlet a2 and connect the first air chamber 201a and the second air chamber 102a, and the flow guiding component 30 switches to the second working mode. Air in the first air chamber 201a is guided by the flow guiding component 30 to the second air chamber 102a, and after being heated by the heating element 103, it is guided back into the room to achieve the heating operation of the bathroom heater. In this implementation, the damper 301 can rotate to the second position along the second direction to close the second air outlet a2. Specifically, closing the second air outlet a2 can be achieved by the damper 301 blocking or covering the second air outlet a2 at the second position, thus preventing air from passing through the second air outlet a2. The first direction and the second direction are opposite directions. For example, the first direction is clockwise and the second direction is counterclockwise. Or, the first direction is counterclockwise and the second direction is clockwise.

[0058] By setting a rotatable damper 301, the size of the damper 301 can meet the requirements of covering the size of the second air outlet a2 and the size of the connecting part of the first air cavity 201a and the second air cavity 102a. By utilizing the installation space of the first air cavity 201a, the structure can be effectively simplified, which is conducive to meeting the miniaturization requirements of the bathroom heater.

[0059] Specifically, the airflow guiding assembly 30 may further include a driving component 302, which is connected to the damper 301 via a transmission connection. The driving component 302 drives the damper 301 to rotate, thereby switching the damper 301 between a first position and a second position. The driving component 302 can be a motor. When the motor rotates clockwise, the damper 301 can rotate clockwise to the first position to open the second air outlet a2. When the motor rotates counterclockwise, the fan 202 can rotate counterclockwise to the second position to close the second air outlet a2. By using the driving component 302 to drive the damper 301, the driving method is relatively simple and can meet the installation requirements of small spaces.

[0060] In some feasible implementations, the drive component 302 can be located inside or outside the first air cavity 201a. When the drive component 302 is located inside the first air cavity 201a, the first housing 201 can exist as an independent housing, and no outer shell structure needs to be provided on its exterior. In this implementation, the size of the bathroom heater can be effectively simplified, achieving miniaturization. When the drive component 302 is located outside the first air cavity 201a, the bathroom heater can also include an outer shell, with multiple first housings 201 disposed inside the outer shell. In this implementation, the aesthetics of the bathroom heater can be improved, and since the drive component 302 is located outside the first air cavity 201a, and the driving end of the drive component 302 penetrates the first housing 201 and connects to the damper 301, the drive component 302 will not interfere with the air inside the first air cavity 201a during operation, effectively reducing wind noise during the operation of the bathroom heater.

[0061] It is worth noting that, such as Figure 2 The damper 301 shown rotates along the length of the bathroom heater. In other words, in this installation method, the rotation axis of the damper 301 extends along the height of the bathroom heater, allowing the damper 301 to swing left and right along its length. In this implementation, the damper 301 can be installed on the left or right side of the second air outlet a2.

[0062] Of course, in other implementations, the damper 301 can also rotate along the height direction of the bathroom heater. That is, in this implementation, the pivot of the damper 301 extends along the length direction of the bathroom heater, allowing the damper 301 to swing up and down along the height direction. In this case, the damper 301 can be positioned above or below the second air outlet a2. Of course, in this implementation, the position of the second air outlet a2 can be... Figure 2 Unlike other types of bathroom heaters, the second air outlet a2 can be offset along the length of the heater.

[0063] In some feasible implementations, the first housing 201 includes a volute, and each volute includes a first air chamber 201a. Specifically, the volute can be spiral-shaped, and the second air outlet a2 and the damper 301 are located in the air outlet area of ​​the volute. Thus, after air enters the spiral volute, with the rotation of the fan 202, it can be directly conducted to the external environment through the second air outlet a2 in the air outlet area, effectively shortening the airflow length and reducing energy loss. Furthermore, the damper 301 is also located on the air outlet side. When the bathroom heater is in hot air mode, it can intercept the air flowing to the second air outlet a2, allowing the air to be directly blocked by the damper 301 and conducted into the second air chamber 102a. The fan 202 can draw gas from the external environment into the first air chamber 201a by rotating itself. For example, a mounting shaft for the fan 202 (not shown in the figure) can be provided at the bottom of the inner housing of the volute.

[0064] Along the height direction of the bathroom heater, the air inlet a1 can be located above the volute, and the air inlet a1 is opened along the axial direction of the volute. This shortens the distance between the air inlet a1 and the volute, allowing air to be drawn into the first air chamber 201a along the axial direction of the volute. The air intake direction is parallel to the axial direction of the volute, which effectively reduces wind noise during the operation of the bathroom heater. At the same time, it effectively utilizes the installation space in the height direction, and through the reasonable design in the height direction, the air conduction channel during the heating process is reduced.

[0065] In some feasible implementations, each first housing 201 and second housing 102 is stacked along the axial direction of the volute. That is, each first housing 201 and second housing 102 is arranged along the height direction of the bathroom heater. In this way, the air inlet a1 is located between the fan assembly 20 and the heating assembly 10, drawing in air along the height direction of the bathroom heater and expelling air from the height direction of the bathroom heater. This can effectively utilize the installation space in the height direction of the bathroom heater, optimize the installation space, and meet the miniaturization requirements of the bathroom heater.

[0066] In one example, see Figure 2 As shown, when there are two first housings 201, the two first housings 201 are arranged along the length of the heating assembly 10. Along the axial direction of the volute, the second housing 102 is stacked on top of the two first housings 201. Alternatively, in other examples, when there are three or more first housings 201, all the first housings 201 are arranged sequentially along the length of the heating assembly 10, and the second housings 102 are stacked on top of all the first housings 201. It should be emphasized that "on top" is relative. Figure 2 In terms of the direction of the middle, it is not a specific limitation.

[0067] Figure 4 This is a schematic diagram of the structure of a body and a cover plate provided in an embodiment of this application.

[0068] Combination Figure 2 and Figure 4 As shown, in the implementation where the first housing 201 includes a volute, the bathroom heater also includes an outer shell structure, with the volute disposed within the outer shell structure. Specifically, the outer shell structure includes a cover plate 40 and a body 50. The cover plate 40 covers the body 50 and together with the body 50 forms a mounting cavity 50a. At least two fan assemblies 20 are disposed within the mounting cavity 50a, and a heating assembly 10 is disposed on the cover plate 40 and located outside the mounting cavity 50a. The body 50 may have a structure with a base plate and four side plates.

[0069] Air inlets a1 are formed on the cover plate 40, and the number of air inlets a1 is the same as the number of fans 202. At least two air inlets a1 are spaced apart along the length of the bathroom heater. For example, when there are two air inlets a1, they are positioned on both sides of the cover plate 40 along the length of the bathroom heater, thus achieving side air intake. By configuring the outer casing as a body 50 and a cover plate 40, the installation requirements between at least two first housings 201 can be met. Simultaneously, the spaced air inlets a1 on the cover plate 40 achieve uniform and symmetrical air intake, reducing wind noise.

[0070] The second air outlet a2 is provided on the main body 50. Specifically, the second air outlet a2 can be provided on the side plate extending along the length direction of the main body 50, and at least two second air outlets a2 can be provided on two opposite side plates of the main body 50.

[0071] For example, when there are two second air outlets a2, they are positioned on opposite side panels. This ensures that when the bathroom heater is in ventilation mode, air is discharged from both outlets a2, resulting in even airflow and preventing wind noise. In this implementation, the two outlets a2 can be positioned opposite each other or staggered. For example, when there are three second air outlets a2, one outlet a2 and two outlets a2 are positioned on opposite side panels of the main body 50. In this implementation, the centers of the three outlets a2 can form a triangular structure, ensuring stable airflow.

[0072] The volute is mounted on the main body 50. The first air chamber 201a also includes a first air guide a3, and the second air chamber 102a also includes a second air guide a4, with the first air guide a3 and the second air guide a4 corresponding in position. It can be understood that the connection between the first air chamber 201a and the second air chamber 102a is achieved through the connection between the first air guide a3 and the second air guide a4.

[0073] Specifically, when the damper 301 rotates to the first position, it closes the first air guide port a3 and the second air guide port a4, thereby isolating the first air chamber 201a from the second air chamber 102a. In this implementation, the damper 301 can cover the first air guide port a3, thus preventing the second air guide port a4 from communicating with the first air chamber 201a through the first air guide port a3, and the bathroom heater is in ventilation mode.

[0074] When the damper 301 rotates to the second position, it opens the first air guide port a3 and the second air guide port a4 to connect the first air cavity 201a and the second air cavity 102a. In this implementation, the damper 301 can open the first air guide port a3, allowing the second air guide port a4 to connect with the second air cavity 102a through the first air guide port a3, and the bathroom heater is in heating mode.

[0075] The first air chamber 201a and the second air chamber 102a are connected by connecting the first air vent a3 and the second air vent a4. This effectively simplifies the connection between the first air chamber 201a and the second air chamber 102a. In conjunction with the damper 301, the damper 301 can be rotated to effectively simplify the opening and closing of the first air vent a3. The operation is simple and does not require any additional connecting parts, thus effectively simplifying the structure.

[0076] In some feasible implementations, the first air vent a3 is opened on the cover plate 40, at least two first air vents a3 are staggered along the length of the bathroom heater, and any one of the first air vents a3 is located between two adjacent air inlets a1.

[0077] For example, there are two first air guide vents a3 and two air inlets a1. In this implementation, the air inlets a1 are located on both sides, and the first air guide vents a3 are located in the middle. This makes efficient use of the opening space on the cover plate 40. Regarding the first air chamber 201a, air enters from the side areas and exits from the middle area, preventing interference between the two first air chambers 201a. This not only makes efficient use of installation space but also effectively reduces wind noise.

[0078] Alternatively, when there are three first air guides a3 and three air inlets a1, the air inlets a1 are spaced apart along the length of the bathroom heater, and two first air guides a3 and one first air guide a3 are respectively set in the interval between two adjacent air inlets a1.

[0079] See also the following for some feasible implementation methods. Figure 2 As shown, in order to meet the installation requirements of the heating component 10, the cross-sectional shape of the air inlet a1 can be semi-circular, or a shape larger than semi-circular composed of arcs and straight lines. The heating component 10 can be installed between two straight lines, thereby avoiding interference between the heating component 10 and the fan 202 due to the installation position.

[0080] Of course, in another feasible implementation, to meet the air intake requirements, the cross-sectional shape of the air inlet a1 can also be designed as circular, and along the height direction of the casing, the air inlet a1 corresponds exactly to the fan 202. In this implementation, the heating component 10 is placed between the two fans 202, and without affecting the air intake, the heating component 10 can block a small part of the air inlet a1.

[0081] For example, when there are two air inlets a1 and two first air guides a3, the two air inlets a1 can be symmetrical, and the two first air guides a3 can be symmetrical. This effectively improves aesthetics while ensuring the stability of air intake and exhaust.

[0082] In some feasible implementation methods, continue to combine Figure 2 and Figure 4 As shown, the cover plate 40 may include a groove structure, and the groove structure at the bottom of the cover plate 40 can be embedded in the top of the body 50. In this way, not only is the connection between the cover plate 40 and the body 50 ensured, but an installation environment is also provided for the heating assembly 10. The outer edge of the top of the cover plate 40 may protrude from the body 50, thereby facilitating the subsequent snapping of the outer casing into a ceiling or other installation location.

[0083] Of course, among other feasible implementation methods, the cover plate 40 can also be configured as a flat plate structure. The specific structure of the cover plate 40 can be adapted to the actual installation conditions of the bathroom heater.

[0084] Figure 5 This is a schematic diagram of the structure of a base provided in an embodiment of this application.

[0085] In some feasible implementation methods, see [reference] Figure 2 and Figure 5 As shown, the second housing 102 includes a base 1021 and an air guide shroud 1022.

[0086] The base 1021 is mounted on the cover plate 40, and the air guide shroud 1022 covers the base 1021, forming a second air cavity 102a. The heating element 103 is mounted on the base 1021 and extends along the length of the outer casing. The heating element 103 is used to heat the air entering the second air cavity 102a.

[0087] Specifically, the base 1021 may include a mounting part 1021a, which can cover the first air guide a3. The mounting part 1021a is provided with a second air guide a4, which is opposite to and communicates with the first air guide a3, thereby realizing air communication between the first air chamber 201a and the second air chamber 102a. The number of second air guides a4 can be one or two. When there are two fans 202, the two first air guides a3 can be located in the central area of ​​the cover plate 40, and the corresponding second air guide a4 can be configured as a large open structure. That is, the bottom of the mounting part 1021a is completely open on the cover plate 40, eliminating the need for a connecting plate structure between the bottom of the mounting part 1021a and the cover plate 40. This simplifies the structure of the heating assembly 10 while meeting connection strength requirements, and is beneficial for the lightweight design of the heating assembly 10. In this implementation, the second air guide a4 at the bottom of the mounting part 1021a can also be provided with an inclined beam. The inclined beam can improve the overall stability of the mounting part 1021a and ensure its service life.

[0088] Of course, when there are two first air guide ports a3, the number of second air guide ports a4 can also be set to two. The second air guide ports a4 can also be set as through holes opened on the bottom plate of the mounting part 1021a. In this implementation, the shape and position of the second air guide ports a4 can correspond to the first air guide ports a3, so that the air in the first air cavity 201a is guided into the second air cavity 102a through the second air guide ports a4. The specific structural form of the mounting part 1021a can be adapted to the actual structure of the cover plate 40.

[0089] Of course, when there are three first air vents a3, the corresponding number of second air vents a4 can be two or three.

[0090] In the above implementation, the heating element 103 is disposed at the second air guide a4. This ensures that when air enters the second air chamber 102a through the second air guide a4, it is immediately heated by the heating element 103, effectively guaranteeing the hot air effect. In this implementation, the length of the heating element 103 can be the same as the length of the mounting portion 1021a, ensuring that all air entering the second air chamber 102a is heated after passing through the heating element 103, thus guaranteeing the heating area. Of course, in other specific implementations, the length of the heating element 103 can be greater than the length of the mounting portion 1021a. For example, the length of the heating element 103 can be the same as the length of the base 1021. Both ends of the heating element 103 can be installed in the clearance portion 1021b. This increases the heating area, thereby improving the hot air conduction efficiency.

[0091] It is worth noting that when the heating element 103 is installed in the mounting part 1021a, its extension direction can be the same as the length direction of the bathroom heater, as shown in the attached figure. Figure 2 As shown. Of course, in another specific implementation, taking two fans 301 as an example, the heating element 103 can also be tilted to match two staggered first air guides a3. When the heating element 103 is tilted, the projection of the heating element 103 towards the volute along the axial direction of the volute can cover both first air guides a3. In this implementation, the mounting part 1021a can also include adapter ends d, with two adapter ends d staggered, and the size of the adapter ends d matching the size of the first air guides a3. In this implementation, both ends of the heating element 103 are located within the adapter ends d, thereby increasing the area of ​​air being heated.

[0092] It should be emphasized that the dimensions and structural form of the installation part 1021a can be adapted to the shape and setting method of the first air guide a3.

[0093] In other implementations, the heating element 103 can also be located at the first air outlet 101, so that all air exiting from the second air chamber 102a can be heated by the heating element 103. In this implementation, the length of the heating element 103 can be the same as the length of the first air outlet 101 to ensure heating effect.

[0094] It should be emphasized that the length of the heating element 103 includes the overall dimensions of the heating element 103, such as the dimensions of the heating section and the dimensions of the mounting ends on both sides of the heating section. The heating element 103 can be mounted on the base 1021 through the mounting ends.

[0095] See also Figure 2The base 1021 also includes at least two clearance portions 1021b, with any one mounting portion 1021a located between the two clearance portions 1021b along the length of the bathroom heater. For example, when there are two fans 202, the number of clearance portions 1021b can be two, and the two clearance portions 1021b are located at both ends of the mounting portion 1021a.

[0096] The avoidance part 1021b avoids the air inlet a1 by a preset distance H along the height direction of the bathroom heater. The specific value of H can be adjusted according to the dimensions of the cover plate 40, the dimensions of the air inlet a1, and the dimensions of the heating component 10.

[0097] Specifically, along the height direction of the bathroom heater, the projection of the avoidance part 1021b onto the main body 50 allows the avoidance part 1021b to partially block the air inlet a1. This ensures the length of the first air outlet 101. Simultaneously, the presence of the preset distance H ensures that there is sufficient air intake space between the air inlet a1 and the avoidance part 1021b, preventing any impact on the air intake volume.

[0098] See also Figure 2 As shown, the base 1021 can be a "T" shaped structure, with two clearance parts 1021b located at both ends and the mounting part 1021a located in the middle. The bottom of the base 1021 is mounted on the cover plate 40, and the top of the base 1021 is covered with an air guide shroud 1022, thereby forming a second air cavity 102a inside the base 1021.

[0099] Of course, among other feasible implementations, the base 1021 can also be of other structures.

[0100] See also Figure 2 As shown, the air guide cover 1022 can be set in the middle of the entire bathroom heater, and the air outlet of the air guide cover 1022 can be designed to have an air guide grille 1022a, thereby forming multiple first air outlets 101. On the one hand, it can achieve uniform air outlet, and on the other hand, it can make the appearance design more symmetrical and improve the aesthetics.

[0101] Of course, in other feasible implementations, the air guide 1022 can also be set in a non-central area to adapt to the adjustment of the spatial layout. For example, when the installation position of the bathroom heater is not in the center of the entire space, the air outlet of the entire space can be uniform by installing an offset air guide 1022.

[0102] Continue to combine Figure 2 and Figure 3As shown, in a specific implementation, the bathroom heater provided in this application embodiment may further include at least two air guides 60. The air guides 60 are used to guide air. The air guides 60 may be disposed at the bottom of the main body 50 and located within the first air cavity 201a. The air guides 60 may be disposed in the air outlet area of ​​the first air cavity 201a. A damper 301 is rotatably disposed between the second air outlet a2 and the air guides 60. The number of air guides 60 is the same as the number of the second air outlet a2 and the number of dampers 301.

[0103] Specifically, when the damper 301 is rotated to the second position, the damper 301 rotates to block the second air outlet a2. The air in the first air cavity 201a passes through the air guide 60, then passes through the first air guide a3 and the second air guide a4 in sequence before entering the second air cavity 102a. The air is then heated in the second air cavity 102a and discharged.

[0104] By setting the air guide 60, air can be better guided from the first air chamber 201a to the second air chamber 102a, which can reduce the friction between the air and the inner wall of the body 50, avoid the air volume waste and air turbulence caused by the air rushing around before entering the second air chamber 102a, and reduce noise and air loss.

[0105] In some feasible implementations, the two air guide components 60 can be staggered along the length of the bathroom heater. This allows for a more rational arrangement of the installation space within the first air chamber 201a, and while meeting the requirements for air channel size and air conduction stability, it also reduces the overall size of the bathroom heater, thus meeting the need for miniaturized bathroom heaters.

[0106] See also Figure 2 and Figure 3 The air guide 60 can be inclined and includes a first end 601 and a second end 602. The first end 601 is close to the fan 202 to guide air, and the second end 602 extends from the first end 601 towards the heating element 10 along the height direction of the bathroom heater. It can be understood that the dimension of the air guide 60 along the height direction of the bathroom heater can be less than or equal to the distance between the heating element 10 and the fan 202. This not only achieves the function of air guidance but also utilizes the original installation distance between the heating element 10 and the fan 202 without changing their positional relationship, effectively saving installation space along the height direction of the bathroom heater and meeting the miniaturization requirements of the bathroom heater.

[0107] When the damper 301 is rotated to the first position, the damper 301 is located at the first end 601, and the air cannot be guided to the second air chamber 102a through the air guide 60. At this time, the second air outlet a2 is in an open state, and the air can be directly discharged through the second air outlet a2, thereby realizing the ventilation mode.

[0108] Specifically, along the height direction of the bathroom heater, the height of the damper 301 should match the height of the air guide 60, so that when the damper 301 is rotated to the first position, the height of the damper 301 can just block the air guide 60, preventing air from being guided to the second air cavity 102a through the gap in the height direction of the damper 301 by the second end 602 of the air guide 60.

[0109] In one specific implementation, the height of the damper 301 can be the same as the height of the air guide 60. Furthermore, when the damper 301 blocks the air guide 60, airflow cannot be achieved between the first air chamber 201a and the second air chamber 102a.

[0110] It should be emphasized that the upper and lower positions are relative in the accompanying drawings of this application embodiment, and do not represent the orientation of the bathroom heater in its installed state. For example, the vertical positional relationship between the components in the drawings may differ from the actual installed state of the bathroom heater. For example, in the installed state of the bathroom heater, the heating component 10 may be located below the fan 202.

[0111] In some feasible implementations, taking a scenario where there are two fans 202, the first end 601 of the air guide 60 is close to one fan 202, and the second end 602 extends away from the first end 601 and connects to the volute corresponding to the other fan 202. This arrangement, with the two air guides 60 staggered along the width of the bathroom heater, effectively utilizes the internal installation space and meets the need for miniaturized use.

[0112] The connection between the first air chamber 201a and the second air chamber 102a is achieved through the first air guide a3, and the first air guide a3 is close to the second end 602 of the air guide 60. The first air guide a3 and the air guide 60 can be located on the same side of the damper 301.

[0113] In one specific implementation, the projection of the first air vent a3 onto the main body 50 along the height direction of the bathroom heater coincides with the air guide 60. Thus, when the damper 301 rotates to the first position, one side of the damper 301 is attached to the first end 601 of the air guide 60, and the other side of the damper 301 is attached to the side of the first air vent a3, thereby rationalizing the positional relationship between the first air vent a3 and the air guide 60 and optimizing the installation space.

[0114] In some feasible implementations, the bathroom heater provided in this application embodiment may also include a T-shaped tee (not shown in the figure). Two ends of the T-shaped tee are respectively connected to two second air outlets a2, and the other end is connected to the external environment, thereby realizing the exhaust function of the bathroom heater.

[0115] It should be emphasized that the external environment mentioned in the above embodiments of this application can be understood as the environment other than the first air cavity 201a and the second air cavity 102a. The external environment may include indoor and outdoor environments. For example, when the bathroom heater is in exhaust mode, the air is directed to the outside, and when the bathroom heater is in hot air mode, the hot air is directed to the inside.

[0116] The following describes the fan 202, which includes an impeller and a motor. The motor controls the rotation of the impeller, the drive component 302 is a stepper motor, and the air guide component 60 is an air guide slope, combined with... Figures 6 to 8 The air conduction direction under different working modes is introduced.

[0117] Figure 6 This is a schematic diagram of the airflow when a bathroom heater is in heating mode, as provided in an embodiment of this application.

[0118] Combination Figure 2 and Figure 6 As shown, when the bathroom heater performs heating operation, the motor drives the impeller to rotate, drawing air into the first air chamber 201a through the semi-circular air inlet a1 on the cover plate 40, as... Figure 6 As shown in the diagram, air A is drawn in. At this time, two stepper motors drive dampers 301-1 and 301-2 to block the second air outlet a2 located on both sides of the main body 50. The drawn-in air is guided through the inclined guide surface, passing sequentially through the first air outlet a3 and the second air outlet a4, as shown in the diagram. Figure 6 As shown in the diagram, the second air duct a4 converges the two streams of air and directs them into the heating element 103. The heating element 103 heats the air, which is then blown out through the first air outlet 101 of the air guide shroud 1022.

[0119] Figure 7 This is a schematic diagram of the airflow when a bathroom heater is in ventilation mode, as provided in an embodiment of this application.

[0120] Combination Figure 2 and Figure 7 As shown, when the bathroom heater performs ventilation, the motor drives the impeller to rotate, drawing air into the first air chamber 201a through the semi-circular air inlet a1 on the cover plate 40. At this time, two stepper motors drive the dampers 301-1 and 301-2 to rotate in front of the inclined air guide, blocking the inclined air guide surface. The air is then guided through the second air outlet a2 on both sides of the main body 50 into the "T"-shaped three-way pipe. Figure 7 The air in the C-shaped tee pipe is connected to the outside and eventually discharged outdoors to complete the ventilation.

[0121] Figure 8 This is a schematic diagram of the airflow when a bathroom heater is simultaneously in ventilation and heating states, as provided in an embodiment of this application.

[0122] Combination Figure 2 and Figure 8 As shown, when the bathroom heater is operating simultaneously for ventilation and heating, the motor drives the impeller to rotate, drawing air into the first air chamber 201a through the semi-circular air inlet a1 on the cover plate 40. Figure 8 As shown in the diagram, air A is blocked by a stepper motor driving damper 301-2, which blocks the second air outlet a2 located on one side of the main body 50. Air B enters the second air chamber 102a through the inclined guide surface and will be used for heating. Another stepper motor drives damper 301-1 to rotate to the front of the inclined guide surface, blocking it. Air C is then guided to the outside through the second air outlet a2 for ventilation.

[0123] It is worth noting that, Figure 8 The quantities of air A, air B, and air C are merely examples and not specific limits.

[0124] The bathroom heater of this application embodiment upgrades the traditional single-fan ventilation and heating function of a bathroom heater to a dual-fan 202, enabling simultaneous ventilation and heating, thus improving the performance of the bathroom heater and reducing operating noise. The function of heating and ventilation can be achieved through intelligent switching between two stepper motors.

[0125] It should be noted that, upon considering the specification and practicing the application disclosed herein, those skilled in the art will readily conceive of other embodiments of this application. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
