Technical Field

[0001] This application relates to the field of household appliance technology, specifically to a bathroom heater / ventilation heater. Background Technology

[0002] As living standards improve, many people have become accustomed to using bathroom heaters when showering. In recent years, bathroom heaters with circular air outlets and rectangular air outlets have become increasingly popular among consumers.

The radial cross-sectional diameter of the second contraction section decreases in the direction away from the opening of the housing assembly, and the minimum diameter of the second contraction section is not greater than the maximum diameter of the air outlet assembly.

[0021] In some embodiments, the air outlet assembly includes:

[0022] An annular air outlet plate, the outer wall of which is the first mating surface, and the annular air outlet plate is connected to the air guide component;

[0023] A flow guide has a third mating surface that is adapted to the shape of the second mating surface. The flow guide is a conical bottom shell, and the diameter of the conical bottom shell gradually decreases from the side away from the flow guide to the side closer to the flow guide.

[0024] In some embodiments, the bathroom heater further includes a driving component, the driving component comprising:

[0025] A rack, one side of which is fixedly connected to the air outlet assembly and the other side of which is movably connected to the air guide assembly; or, one side of which is movably connected to the air outlet assembly and the other side of which is fixedly connected to the air guide assembly.

[0048] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0049] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0050] In the description of this application, it should be understood that the terms "upper," "lower," "horizontal," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In this application, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0051] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two entities at the point of connection are not connected through a transitional structure, but are simply linked together to form a whole. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0052] In this application, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0053] See Figure 1 and Figure 2 This application provides a bathroom heater / ventilation unit. This unit can be wall-mounted, ceiling-mounted, or recessed, etc., and this application does not impose any specific limitations on it. This bathroom heater / ventilation unit has good stain-proofing properties.

[0054] A bathroom heater may include: a housing assembly 1, an air inlet assembly 2, a heating assembly 3, an air guide assembly 4, and an air outlet assembly 5.

[0055] The housing assembly 1 has an opening 11 for discharging gas from inside the housing assembly 1. An air inlet assembly 2 is disposed within the housing assembly 1 and configured to introduce gas from outside the housing assembly 1 into the housing assembly 1. A heating assembly 3 is disposed within the housing assembly 1 and configured to heat the gas inside the housing assembly 1. An air guide assembly 4 is disposed within the housing assembly 1 and configured to guide the gas inside the housing assembly 1 to the opening 11. An air outlet assembly 5 moves relative to the opening of the housing assembly 1 through relative movement with the air guide assembly 4, switching between a first position and a second position. When the air outlet assembly 5 is in the first position, there is a gap between the air outlet assembly 5 and the side wall of the opening 11 of the housing assembly 1 to open the opening 11 of the housing assembly 1, allowing the heated gas to be discharged. When the air outlet assembly 5 is in the second position, the air outlet assembly 5 contacts the side wall of the opening 11 of the housing assembly 1 to close the opening 11 of the housing assembly 1, preventing external dirt from entering the interior of the housing assembly 1 through the opening 11 of the housing assembly 1.

[0056] Specifically, when the user adjusts the bathroom heater to heating or ventilation mode, the air outlet component 5 is in the first position, with a gap between it and the side wall of the opening 11 of the housing component 1. At this time, air from outside the housing component 1 enters the housing component 1 through the air inlet component 2, the heating component 3 heats the air inside the housing component 1, and the air guide component 4 guides the heated air to the opening 11 of the housing component 1. The heated air is then discharged into the room through the annular air outlet, achieving indoor heating or ventilation. When the user turns off the bathroom heater, the air outlet component 5 is in the second position, contacting the side wall of the opening 11 of the housing component 1, closing the opening 11 and achieving a seal.

[0057] With this configuration, the air outlet component 5 and the air guide component 4 can be adjusted to the second position when the bathroom heater is not in operation, so that the opening 11 of the housing component 1 is closed, thereby preventing external dirt from entering the interior of the housing component 1. This avoids the problem of dirt accumulation caused by the opening 11 of the housing component 1 being open for a long time, reduces the difficulty of cleaning, and improves the user experience.

[0058] In some embodiments, see Figure 1 , Figure 2 as well as Figure 4 The housing assembly 1 may include a housing 12 and a panel 13, forming a double-layer protective structure, which is beneficial to protect the internal structure of the housing 12, thereby improving the service life of the bathroom heater.

[0059] The housing 12 may have a first through hole 123 and a second through hole 124. The first through hole 123 allows gas from outside the housing 12 to enter the housing 12, and the second through hole 124 allows gas guided by the air guide assembly 4 to exit the housing 12. The housing 12 may also include a housing cover 121 and a housing base 122 with a second opening. The housing base 122 is fixed to a wall or ceiling by pre-embedded bolts. The housing cover 121 is detachably connected to the housing base 122 and covers the internal structure of the housing base 122 to facilitate maintenance of the internal structure of the housing 12.

[0060] Panel 13 can be connected to the side of housing 12 with the second through hole 124 to cover housing 12 and improve the aesthetics of the bathroom heater. Panel 13 has a third through hole 131, which is the opening 11 of housing assembly 1. The third through hole 131 communicates with the second through hole 124 so that the gas guided by the air guide assembly 4 passes through the second through hole 124 and the third through hole 131 in sequence and is discharged to the outside of the bathroom heater.

[0061] Specifically, indoor air enters the housing 12 through the first through hole 123. The heating component 3 heats the air inside the housing 12. The air guide component 4 guides the heated air to the second through hole 124. The air in the second through hole 124 flows to the third through hole 131. By switching the position of the air outlet component 5, the contact state between the air outlet component 5 and the side wall of the third through hole 131 is adjusted, so as to close or open the third through hole 131, that is, to close or open the opening 11 of the housing component 1. This allows the user to close the opening 11 of the housing component 1 when the bathroom heater is not in operation, preventing external dirt from entering the housing component.

[0062] In some embodiments, see Figure 2 and Figure 4 When the air outlet component 5 is in the second position, the end of the air outlet component 5 facing away from the inner cavity of the housing component 1 is coplanar with the panel 13. This end of the air outlet component 5 facing away from the inner cavity of the housing component 1 is the end of the air outlet component 5 facing away from the air guide component 4. This arrangement ensures that when the opening 11 of the housing component 1 is closed, the end of the air outlet component 5 facing away from the air guide component 4 forms a flat surface with the panel 13, improving the overall aesthetics of the bathroom heater. Simultaneously, it avoids dust accumulation and bumps caused by the protruding or recessed end of the air outlet component 5 facing away from the air guide component 4, further reducing the cleaning difficulty and maintenance cost of the bathroom heater.

[0063] Specifically, when the user turns off the bathroom heater, the end of the air outlet component 5 that is away from the air guide component 4 is moved to be coplanar with the panel 13; this setting makes the overall structure of the bathroom heater more compact and occupies less space when it is not in operation.

[0064] In some embodiments, see Figure 1 and Figure 2 The air intake assembly 2 may include: an air intake plate 21, a fan 22, and a second drive component 23.

[0065] The air inlet plate 21 is rotatably connected to the panel 13, which has an air inlet 132. The air inlet plate 21 can either close or expose the air inlet 132. The air inlet plate 21 can be rotatably connected to the edge of the air inlet 132 on the panel 13 via a pivot or hinge. This arrangement ensures that when the air inlet plate 21 is closed, it completely covers the air inlet 132, thus preventing foreign objects and dirt from entering the bathroom heater through the air inlet 132. This ensures the normal operation of the bathroom heater and facilitates cleaning. The fan 22 is installed inside the housing base 122 and is connected to the air inlet 132. It is used to draw indoor air into the housing assembly 1. The fan 22 can be selected according to actual needs; for example, a centrifugal fan or an axial fan can be used, all of which fall within the scope of protection of this application. The output end of the second driving component 23 is coaxially connected to the fan 22 and is used to drive the fan 22 to rotate, thereby driving the fan 22 to work; the second driving component 23 can be a motor, a stepper motor or a servo motor, etc., all of which are within the protection scope of this application.

[0066] In some embodiments, see Figure 1 and Figure 2 The heating component 3 may include a heating mounting base 31 and a heating block 32.

[0067] The heating mounting base 31 is installed inside the housing assembly 1 to securely support the heating block 32. The heating block 32 is connected to the heating mounting base 31 and generates heat to heat the gas inside the housing assembly 1. The heating block 32 can be a ceramic heating block or a carbon fiber heating block. The heating block 32 in this application is a commercially available product and will not be described in detail here.

[0068] In some embodiments, see Figure 1 and Figure 2 The heating block 32 can be partially exposed to the heating mounting base 31, and the exposed part of the heating block 32 faces the air inlet assembly 2, so that the gas entering from the air inlet assembly 2 can directly contact the heating block 32, thereby improving the heating efficiency.

[0069] In some embodiments, see Figure 1 and Figure 2 The air guiding assembly 4 may include an air guiding element 41 and an outer ring plate 42. The air outlet end of the air guiding element 41 faces the opening 11 of the housing assembly 1. The air guiding element 41 is connected to the air outlet assembly 5, and the heated gas is guided to the opening 11 of the housing assembly 1 through the air guiding element 41. The outer ring plate 42 is disposed on the side wall of the opening 11 of the housing assembly 1. One end of the outer ring plate 42 away from the opening 11 of the housing assembly 1 is connected to the air guiding element 41. The air outlet assembly 5 has a first mating surface, and the outer ring plate 42 has a second mating surface that matches the shape of the first mating surface. The first mating surface and the second mating surface can achieve shape matching by means of planar mating, curved mating, or conical mating.

[0070] Specifically, when the air outlet assembly 5 is in the first position, the first mating surface and the second mating surface are separated, and the opening 11 of the housing assembly 1 is open. At this time, the heated gas can be smoothly discharged through the annular air outlet to achieve indoor heating or ventilation. When the air outlet assembly 5 is in the second position, the first mating surface and the second mating surface are in contact, and the opening 11 of the housing assembly 1 is closed. At this time, it can effectively prevent external dirt from entering the interior of the housing assembly 1, avoiding the problem of dirt accumulation caused by the opening 11 of the housing assembly 1 being in an open state for a long time, thereby reducing the difficulty of cleaning and improving the user experience.

[0071] With this configuration, when the user turns off the bathroom heater, the opening 11 of the housing assembly 1 can be closed by the second mating surface on the outer ring plate 42 contacting the first mating surface on the air outlet assembly 5, which is convenient to operate. In addition, during the relative movement of the air outlet assembly 5 and the air guide 41, the outer ring plate 42 can constrain the movement trajectory of the air outlet assembly 5, thereby preventing the air outlet assembly 5 from deviating.

[0072] In some embodiments, see Figure 1 and Figure 2 The air guide component 41 includes an annular air guide base 411 and an annular air guide seat cover 412. The separate annular air guide base 411 and annular air guide seat cover 412 facilitate installation, disassembly, and maintenance of the internal structure of the air guide component 41. The annular air guide base 411 has a first opening, facilitating the introduction of heated gas into the air guide assembly 4, thereby improving the air guiding efficiency of the bathroom heater. The annular air guide seat cover 412 closes the first opening and is positioned close to the outer ring plate 42, facilitating the guidance of gas through the air guide assembly 4 to the opening 11 of the housing assembly 1, improving the air output effect of the bathroom heater.

[0073] In some embodiments, see Figure 1 and Figure 2 When the air outlet assembly 5 is in the first position, the first mating surface can be away from the opening 11 of the housing assembly 1 and located outside the housing assembly 1, that is, the air outlet assembly 5 is set to be external. With this configuration, when the air outlet assembly 5 is in the first position, the first mating surface is exposed outside the housing assembly 1, so that the airflow discharged from the opening 11 of the housing assembly 1 is discharged into the room in an expanded manner, thereby improving the uniformity of the indoor airflow.

[0074] In some embodiments, see Figure 1 and Figure 2When the air outlet assembly 5 is in the first position, with its first mating surface away from the opening 11 of the housing assembly 1 and located outside the housing assembly 1, the axial outer contour of the outer ring plate 42 can be a variable diameter structure. The radial cross-sectional diameter of the variable diameter structure can decrease along the direction away from the opening 11 of the housing assembly 1, forming an outwardly convex arc or conical structure. The minimum diameter of the variable diameter structure is not greater than the maximum diameter of the air outlet assembly 5, ensuring that the air outlet assembly 5 will be engaged at the minimum diameter of the variable diameter structure or just in contact with the minimum diameter of the variable diameter structure, thereby closing the opening. The axial direction of the outer ring plate 42 is the y-direction (see...). Figure 2 The radial direction of the variable diameter structure is the x-direction (see...). Figure 2 ).

[0075] Specifically, the variable diameter structure of the outer ring plate 42 forms a conical sealing structure with the air outlet component 5. During the process of the air outlet component 5 moving to the second position, the variable diameter structure of the outer ring plate 42 causes the second mating surface to gradually contact and press against the first mating surface, thereby improving the sealing effect between the second mating surface and the first mating surface.

[0076] In some embodiments, see Figure 1 and Figure 3 When the air outlet component 5 is in the first position, the first mating surface can be away from the opening 11 of the housing component 1 and located inside the housing component 1, that is, the air outlet component 5 is set to be built-in. With this configuration, when the air outlet component 5 is in the first position, the first mating surface is located inside the housing component 1, so that an annular air gathering channel is formed between the air outlet component 5 and the outer ring plate 42.

[0077] Specifically, when the air outlet component 5 is in the first position, the gas heated by the heating component 3 enters the annular air gathering channel from the air outlet end of the air guide component 41. The hot airflow gathers in the annular air gathering channel and is discharged into the room from the opening 11 of the housing component 1. This setting increases the airflow velocity at the opening 11 of the housing component 1, thereby increasing the airflow penetration, reducing the time it takes for the bathroom heater's airflow to reach the ground, and improving the user experience.

[0078] In some embodiments, see Figure 1 , Figure 2 and Figure 3 When the air outlet assembly 5 is in the first position and the first mating surface is inside the housing assembly 1, the axial outer contour of the outer ring plate 42 can be a variable diameter structure. The radial cross-sectional diameter of the variable diameter structure can increase in the direction away from the opening 11 of the housing assembly 1, forming an outwardly protruding arc or conical structure. The minimum diameter of the variable diameter structure is not greater than the maximum diameter of the air outlet assembly 5, so that when the air outlet assembly 5 moves to the minimum diameter of the variable diameter structure, it is ensured that the air outlet assembly 5 will be stuck at the minimum diameter of the variable diameter structure or just in contact with the minimum diameter of the variable diameter structure, thereby closing the opening.

[0079] Specifically, the variable diameter structure of the outer ring plate 42 forms an inverted conical sealing structure with the air outlet component 5. When the air outlet component 5 moves to the second position, the variable diameter structure of the outer ring plate 42 causes the second mating surface to gradually contact and press against the first mating surface, thereby improving the sealing effect between the second mating surface and the first mating surface.

[0080] In some embodiments, see Figure 1 and Figure 3 When the air outlet assembly 5 is in the first position, with the first mating surface located inside the housing assembly 1, the axial outer contour of the outer ring plate 42 can be a variable diameter structure. This variable diameter structure can include a protruding section, a first contracting section, and a second contracting section. The protruding section has a maximum diameter. The first contracting section is located on the side of the protruding section near the opening 11 of the housing assembly 1, and the radial cross-sectional diameter of the first contracting section decreases along the direction near the opening 11 of the housing assembly 1. The second contracting section is located on the side of the protruding section away from the opening 11 of the housing assembly 1, and the radial cross-sectional diameter of the second contracting section decreases along the direction away from the opening 11 of the housing assembly 1. The minimum diameter of the second contracting section is not greater than the maximum diameter of the air outlet assembly 5, ensuring that when the air outlet assembly 5 moves to the minimum diameter of the first contracting section, the air outlet assembly will be stuck at or exactly in contact with the minimum diameter of the first contracting section, thereby closing the opening.

[0081] Specifically, when the air outlet assembly 5 moves to the second position, the gas heated by the heating assembly 3 is discharged from the air outlet end of the air guide 41. First, the gas flows to the second contraction section to achieve airflow concentration, which improves the airflow penetration. This causes the gas flow velocity to increase when it flows to the protrusion section. Then, the gas flow velocity increases again when it flows to the first contraction section, further improving the airflow penetration.

[0082] In some embodiments, see Figure 1 and Figure 2 The air outlet assembly 5 may include an annular air outlet plate 51. The outer wall of the annular air outlet plate 51 is a first mating surface, and the annular air outlet plate 51 is connected to the air guide 41. This arrangement facilitates the shape adaptation between the first mating surface and the second mating surface.

[0083] In some embodiments, see Figure 1 and Figure 2 The air outlet assembly 5 may further include a flow guide. The flow guide is disposed on the side of the annular air outlet plate 51 near the air guide 41 to optimize the air outlet effect and make the gas more evenly discharged from the bathroom heater. The flow guide can be a flow vane, a flow guide ring, or a flow guide plate, etc. Any flow guide that can achieve uniform gas discharge is within the protection scope of this application.

[0084] In some embodiments, see Figure 1 and Figure 2The guide component has a third mating surface, at least a portion of which is adapted to the shape of the first mating surface, thereby creating a tighter fit between the guide component and the annular air outlet plate 51 and improving the sealing effect. In this application, only a portion of the third mating surface may be adapted to the shape of the first mating surface. In this case, the guide component can have a certain gap in the area where it does not fit the shape of the first mating surface to adapt to the structure; this setting ensures the sealing effect while reducing the requirements for the machining accuracy of the guide component. In this application, all the third mating surfaces may also be adapted to the shape of the first mating surface. In this case, a complete sealing fit is formed between the guide component and the air outlet assembly 5, improving the sealing effect.

[0085] In some embodiments, see Figure 1 and Figure 2 The guiding surface of the flow guide can be a curved surface, a composite surface combining a plane and a curved surface, or a combination of multiple curved surfaces with different radii of curvature. Any flow guide that can achieve smooth gas outflow by setting a suitable guiding surface falls within the scope of protection of this application. Specifically, in this application, the guiding surface of the flow guide is a curved surface. The curved surface setting can more effectively guide gas flow, allowing the gas to maintain a relatively stable flow velocity and direction during the flow guidance process, thereby reducing resistance and improving air outlet efficiency.

[0086] In some embodiments, see Figure 1 and Figure 2 The air guide is a conical bottom shell 52, the diameter of which gradually decreases from the side away from the air guide 41 to the side closer to the air guide 41. The gradually decreasing diameter of the conical bottom shell 52 causes the gas flowing out from the annular air outlet 51 to be constrained by the gradually expanding sidewall at the air guide, thereby enabling the gas to be discharged more evenly to the outside of the bathroom heater.

[0087] In some embodiments, see Figure 1 , Figure 2 as well as Figure 4 The bathroom heater may further include a drive component 6, configured to drive the air outlet component 5 and the air guide component 4 to move relative to each other, switching between a first position and a second position. The drive component 6 can drive the air outlet component 5 to move relative to the air guide component 4 in any direction. For example, the air outlet component 5 can move relative to the air guide component 4 in a straight line, or it can move relative to the air guide component 4 in a curved direction. Any movement mode that enables adjustment of the relative position between the air outlet component 5 and the air guide component 4 falls within the scope of protection of this application.

[0088] In some embodiments, see Figure 1 , Figure 2 and Figure 4The drive assembly 6 is configured to drive the air outlet assembly 5 to move relative to the air guide assembly 4 along the axial direction of the opening 11 of the housing assembly 1, making the relative movement between the air outlet assembly 5 and the air guide assembly 4 smoother and easier to control. The axial direction of the opening 11 of the housing assembly 1 is the y-direction (see [reference]). Figure 2 This setting helps improve the stability of the airflow and the sealing effect of the bathroom heater.

[0089] In some embodiments, see Figure 1 and Figure 4 The drive component 6 can be installed on the central axis of the air outlet component 5 or at other suitable locations off the central axis. Any drive component 6 that enables relative movement between the air outlet component 5 and the air guide component 4 falls within the scope of protection of this application. Specifically, in this application, the drive component 6 is installed on the central axis of the air outlet component 5. This arrangement avoids eccentric vibration caused by uneven driving force, thereby ensuring that the air outlet component 5 remains balanced during movement and guaranteeing the stability of the bathroom heater operation.

[0090] In some embodiments, see Figure 1 , Figure 2 as well as Figure 5 The drive assembly 6 may include a rack 61, a gear 62, and a first drive member 63. One side of the rack 61 is fixedly connected to the air outlet assembly 5, and the other side of the rack 61 is movably connected to the air guide assembly 4; alternatively, one side of the rack 61 is movably connected to the air outlet assembly 5, and the other side of the rack 61 is fixedly connected to the air guide assembly 4. The gear 62 meshes with the rack 61. The output end of the first drive member 63 is coaxially connected to the gear 62.

[0091] Specifically, the first driving component 63 drives the gear 62 to rotate, and the rotation of the gear 62 drives the rack 61 to move synchronously, so as to realize the relative movement of the air outlet component 5 and the air guide component 4, thereby realizing the switching between the first position and the second position.

[0092] The drive component 6 can also be a screw and nut transmission mechanism, with the nut connected to the air outlet component 5. The relative movement between the air outlet component 5 and the air guide component 4 is achieved by rotating the screw and causing the nut to move along the screw axis. Alternatively, the drive component 6 can also be a linkage and slider mechanism, with the slider connected to the air outlet component 5. The relative movement between the air outlet component 5 and the air guide component 4 is achieved by the sliding or telescoping of the linkage along the guide rail. This application does not limit the specific structure of the drive component 6; any arrangement that enables the relative movement between the air outlet component 5 and the air guide component 4 through the drive component 6 falls within the scope of protection of this application.

[0093] In some embodiments, see Figure 1The annular air guide cover 412 can be provided with a clearance hole for the drive component 6 to pass through. This setting allows the drive component 6 to pass smoothly through the annular air guide cover 412 and connect with the air outlet component 5, thereby realizing the relative movement adjustment between the air outlet component 5 and the air guide component 4.

[0094] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application. It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solutions of the embodiments of this application should be included within the protection scope of the embodiments of this application.
