Description

Technical Field

[0001] This utility model relates to the field of bathroom heater technology, and in particular to a bathroom heater installation structure that prevents drafts. Background Technology

[0002] As a commonly used heating and ventilation device in bathrooms, the installation method of a bathroom heater directly affects its performance and safety. Traditional bathroom heaters are mostly installed directly in the ceiling, with the panel and main unit working together to achieve their function. However, the existing installation structure has certain drawbacks: on the one hand, there is often an assembly gap between the panel and the main unit, allowing cold air or dust from the ceiling layer to enter the main unit through the air inlet, affecting the normal operation of the equipment and even shortening its lifespan; on the other hand, traditional installation methods mostly rely on direct fixing with screws, making the installation process cumbersome and inconvenient for later maintenance and adjustment.

[0003] Furthermore, some existing technologies attempt to improve sealing by adding sealing strips or modifying the panel structure, but they still struggle to completely prevent the intrusion of interstitial air, especially in humid environments where sealing materials are prone to aging and failure, further reducing their effectiveness in preventing interstitial air intrusion. Therefore, there is an urgent need in this field for a bathroom heater installation structure that is structurally sound, easy to install, and effectively prevents the intrusion of interstitial air. Summary of the Invention

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this utility model is to provide a bathroom heater installation structure that prevents drafts by optimizing the connection between the panel and the main unit, adding an air intake hood and a wind-guiding structure, effectively isolating drafts, and improving installation efficiency and reliability.

[0005] This utility model also provides a bathroom heater installation structure to prevent airflow from being trapped between the hinges, including a main unit and a panel. The main unit is located on the back of the panel. The back of the panel is provided with a rotatable hinge and a motor for driving the hinge to rotate. One end of the hinge is provided with a insertion post serving as a rotation shaft, and the output end of the motor is connected to the other end of the hinge. The front surface of the main unit is provided with an air inlet, and an air inlet cover is installed at the air inlet. The opening end of the air inlet cover is set towards the back of the hinge to form a guide air duct between the back of the hinge and the opening end of the air inlet cover.

[0006] Specifically, the edge of the panel is provided with a locking device for snapping the panel into the mounting frame.

[0007] Specifically, the back of the panel is provided with a left cover and a right cover on both sides of the hinge, and the left cover, the right cover and the panel body together form a U-shaped air duct chamber that constrains the airflow direction.

[0008] Specifically, the back of the panel is provided with an air guide plate, and the front surface of the main unit is provided with a support frame. In the installed state, the free end of the support frame abuts or connects with the side surface of the air guide plate to assist in supporting and positioning the main unit.

[0009] Specifically, the front surface of the main unit is connected to the air intake shroud by detachable fasteners.

[0010] Specifically, it also includes a ceiling and a mounting frame. The mounting frame is fixedly installed on the back of the ceiling. The ceiling has a panel opening. The mounting frame has a frame opening corresponding to the panel opening. The panel is embedded in the frame opening. One end of the locking member is locked onto the edge of the frame opening.

[0011] Specifically, the air intake shroud has a partition plate inside, which is located in the central area of ​​the air intake and is used to divide the intake airflow into multiple streams.

[0012] Specifically, the front surface of the host is connected to the support frame by detachable fasteners.

[0013] Specifically, the opening edge of the air intake shroud is provided with a sealing element to form a sealed contact with the back of the panel when installed.

[0014] Specifically, the free end of the support frame is provided with a slot, and the side surface of the air guide plate is provided with a protruding rib adapted to the slot, and the slot and the protruding rib are engaged. Specifically, the edge of the panel is provided with a locking element.

[0015] The beneficial effects of this utility model are as follows: 1. By setting an air intake hood, this structure directly connects the air intake of the main unit to the space behind the panel, effectively blocking cold air, dust, or humid air from the upper ceiling layer from entering the main unit, avoiding the risk of equipment performance degradation or short circuits, and improving product lifespan and operational stability. 2. This structure also utilizes a hinged structure linked to a motor to achieve controllable opening and closing of the panel, which not only facilitates installation and maintenance but also further optimizes the sealing and guiding of the air inlet and outlet ducts, reducing energy loss. 3. The panel edge is equipped with locking components that can be quickly engaged with the mounting frame. Combined with the placement installation method of the air intake hood and support frame, the assembly process is greatly simplified, the use of screws is reduced, installation efficiency is improved, and the difficulty of subsequent disassembly is reduced. 4. An air guide plate is set on the back of the panel, which enhances the rationality of airflow organization, avoids direct blowing and eddies, and improves user comfort; at the same time, the support frame and the side surface of the air guide plate cooperate to enhance the stability of the main unit suspension and the overall structural strength. V. A partition plate is installed inside the air intake hood, located in the center of the air intake, which can balance the airflow, reduce turbulence and noise, and further improve air intake efficiency and user experience. VI. The overall structural design is reasonable, suitable for mass production and market promotion. While enhancing the anti-wind-layer function, it does not significantly increase costs, and has high practicality and economy. Attached Figure Description

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Example 1: See Figures 1 to 7 This utility model provides a bathroom heater installation structure to prevent "interstitial draft". The core design concept of this structure is to construct a completely sealed or clearly oriented independent air duct between the air inlet of the main unit 3 and the back of the panel 4 through an independent air intake hood 5. This physically isolates the air in the upper layer of the ceiling 1 (also known as the suspended ceiling space), ensuring that all the air drawn in by the main unit 3 comes from the air inside the bathroom that flows in through the opening of the panel 4, thus completely eliminating the "interstitial draft" phenomenon.

[0027] The installation structure mainly includes a ceiling 1, a mounting frame 2, a main unit 3, a panel 4, an air intake hood 5, and a support frame 6. The ceiling 1 is a component of the bathroom ceiling and is typically made of materials such as aluminum composite panels or gypsum board. The mounting frame 2 is a component independent of the main unit 3 and the panel 4; its function is to provide a sturdy, flat, and easily adjustable mounting base for the panel 4.

[0028] like Figure 4 As shown, the ceiling 1 has a suitably sized opening 101. The mounting frame 2 is fixed to the back of the ceiling 1 (i.e., inside the interlayer) by self-tapping screws, clips, or other conventional connection methods. The mounting frame 2 has a frame opening 201 in the middle corresponding to the opening 101. The opening 101 and the frame opening 201 together form the installation opening for the bathroom heater. The panel 4 is embedded in the frame opening 201, so that its front is flush with the decorative surface of the ceiling 1, achieving an aesthetically pleasing visual effect.

[0029] like Figures 1 to 3As shown, the front surface of panel 4 is the part directly visible to the user, while the back of panel 4 serves as the mounting base for various functional components. At least two, typically four, symmetrically distributed locking elements 402 are provided along its edges. These locking elements 402 can be elastic metal clips or plastic claws. During installation, by pressing panel 4, one end of the locking element 402 extends past the edge of frame opening 201 and engages with it, thereby achieving a quick and secure connection between panel 4 and mounting frame 2. Assembly and disassembly can be completed without tools, greatly facilitating daily maintenance and cleaning.

[0030] A movable hinge 401 is located in the center of panel 4. This hinge 401 is not a traditional book hinge; it should be broadly understood as a rotatable damper or air guide. One end of hinge 401 has a insertion post 405, which is embedded in a corresponding bearing seat or groove on the back of panel 4, forming the rotation axis of hinge 401. The other end of hinge 401 is connected to the output shaft of a micro motor 407. This motor 407 is fixedly mounted on the back of panel 4 and, upon receiving user commands (such as switching between heating, blowing, and ventilation modes), can drive hinge 401 to rotate around the insertion post 405 at a certain angle. When hot or cold air needs to be blown out, hinge 401 opens (e.g., when...). Figure 3 (as shown in the diagram); when the device is in standby mode or only requires lighting, hinge 401 can be closed to prevent dust and keep the device warm.

[0031] To ensure the effectiveness of airflow organization during hinge 401 rotation and to prevent airflow leakage to both sides, a left cover 403 and a right cover 404 are respectively provided on the back of panel 4 and on the left and right sides of hinge 401. The left cover 403, the right cover 404, and the panel 4 body together form an approximately "U"-shaped air duct chamber, which strictly confines the airflow guided by hinge 401 to its front, effectively improving airflow efficiency and directionality.

[0032] In addition, an air guide plate 406 is fixedly installed on the back of panel 4. The air guide plate 406 is located below the hinge 401, and its cross-section can be arc-shaped or inclined plane. Its main function is to guide the airflow led out by hinge 401 further towards the center of the bathroom space, avoiding the airflow from blowing directly to the ceiling or circulating only near the panel, thereby improving the temperature balance efficiency and ventilation efficiency of the bathroom heater.

[0033] like Figure 2 and Figure 7As shown, the main unit 3 is the core functional component of the bathroom heater, integrating a heating module (such as a PTC ceramic heating element), a fan (centrifugal or cross-flow impeller), an air exchange module, and a circuit control board. The main unit 3 intakes and exhausts air through its front surface (the side facing panel 4). One or more air inlets are provided on its front surface. One key improvement of this invention is the installation of an independent, cylindrical or hood-shaped air intake cover 5 on the air inlet.

[0034] The air intake shroud 5 is preferably made of ABS engineering plastic through one-time injection molding, which has good strength, flame retardancy and weather resistance. It is firmly connected to the front surface of the main unit 3 by screws, completely surrounding the air intake of the main unit 3. The size, shape and orientation of the opening end of the air intake shroud 5 (i.e. the end away from the main unit 3) are carefully designed, with its opening facing directly and closely towards the hinge 401 on the back of the panel 4 and the air duct chamber formed by the left and right shroud bodies 403 and 404.

[0035] More preferably, a partition plate 501 is provided at the center of the interior of the air intake hood 5. The partition plate 501 divides the inner cavity of the air intake hood 5 into two sub-air ducts. This design corresponds to the dual air intake structure of the fan impeller inside the main unit 3, which can balance the negative pressure of the air intake on both sides, reduce turbulence, reduce wind noise, and improve the working efficiency and stability of the fan.

[0036] The main unit 3 is installed and fixed within the ceiling cavity via a support frame 6. The support frame 6 is fixed to the front surface of the main unit 3 by screws or snap-fit ​​connections, typically located on either side or below it. During installation, the free end of the support frame 6 (the end furthest from the main unit 3) is securely rested on a wooden or metal support frame pre-installed on the ceiling joists. Another ingenious design of this invention is that the top of the support frame 6 is not suspended in mid-air, but rather tightly abuts against or is connected to the side surface of the air guide plate 406 on the back of the panel 4 (see...). Figure 3 This not only provides an additional support point for the main unit 3, enhancing the stability of the overall structure and preventing the main unit 3 from shifting or making noise due to fan vibration, but more importantly, it forms a structural "interlock" that physically connects the main unit 3 and the panel 4, ensuring that the opening of the air intake shroud 5 can always be accurately aligned with the air duct on the back of the panel 4, maintaining the integrity and sealing of the independent air duct.

[0037] The working principle and anti-cavitation process of this structure are as follows: After installation, the panel 4 is tightly secured to the mounting frame 2 by the locking piece 402. Any minor gaps that may exist between the back of the panel 4 and the joint between the ceiling 1 and the mounting frame 2 are blocked by the structure of the panel 4 itself or by any possible sealing strips. When the bathroom heater starts working, negative pressure is generated inside the main unit 3, requiring air to be drawn in.

[0038] In traditional structures, negative pressure draws air in from both the panel 4 opening and the ceiling interlayer through various assembly gaps, causing "interlayer wind" to mix in.

[0039] In this invention, the opening of the air intake hood 5 is directly aligned with the effective air duct formed on the back of the panel 4. Since this path is the one with the least resistance to airflow to the main unit 3, most of the air will preferentially and centrally enter the air intake hood 5 from the bathroom environment, the opening on the front of the panel 4, the channel after the hinge 401 is opened, and finally flow into the air inlet of the main unit 3.

[0040] At this point, the interlayer space above the ceiling 1 and the air inlet of the main unit 3 are physically separated by components such as the panel 4, mounting frame 2, and air intake hood 5. Air in the interlayer cannot find a low-resistance path to enter the main unit 3, thus being completely blocked.

[0041] The cooperation between the support frame 6 and the air guide plate 406 further secures the relative positions of the main unit 3 and the panel 4, ensuring the long-term accuracy of the aforementioned air duct connection. The partition plate 501 inside the air intake shroud 5 optimizes the air intake airflow and improves the overall performance of the machine.

[0042] Example 2: Based on Example 1, this example further optimizes the air intake shroud 5. The opening edge of the air intake shroud 5 can be integrally molded or a high-elasticity sealing sponge strip or silicone ring can be added later. When the main unit 3 is finally installed, the sealing ring is slightly compressed and tightly adheres to a specific area on the back of the panel 4 (e.g., the edge of the chamber formed by the left shroud 403 and the right shroud 404), thereby forming a soft, highly sealed interface between the air intake shroud 5 and the panel 4. This design can completely eliminate the tiny gaps that may occur due to manufacturing tolerances or long-term use, providing the highest level of protection against air leakage, while also providing additional beneficial effects of vibration reduction and noise reduction.

[0043] Example 3: Based on Example 1, this example refines the support frame 6 and its connection method with the air guide plate 406. The top of the support frame 6 can be designed as a "U"-shaped or "V"-shaped slot. A matching protruding rib or pivot can be designed at the corresponding position of the air guide plate 406 on the back of the panel 4. During installation, simply align the slot of the support frame 6 with the rib of the air guide plate 406 to achieve a quick and precise connection. Compared to simple contact, this snap-fit ​​connection is more robust and reliable, effectively preventing the main unit 3 from shifting under unexpected external forces (such as severe vibration or collisions during transport), further enhancing the stability and reliability of the structure.

[0044] Example 4: In Example 1, the hinge 401 is driven by the motor 407. In this example, a purely mechanical drive scheme can be considered. For example, the motor 407 can be omitted, and a lever or gear can be provided at the connection end of the hinge 401. At the same time, a transmission mechanism (such as a linkage or wire) that is linked to the user's knob or switch can be provided inside the panel 4. When the user operates the switch, the hinge 401 is driven to open or close through mechanical transmission. This scheme reduces manufacturing costs and circuit complexity, and is suitable for cost-sensitive basic models. Although the convenience of remote control and intelligent control is lost, the core anti-wind-blocking function is fully realized by retaining the air intake shroud 5 and other structures.

[0045] Example 5: To ensure stable operation in the high-temperature and high-humidity bathroom environment over a long period, all plastic components of this installation structure (including panel 4, air intake hood 5, left hood 403, right hood 404, and air guide plate 406) should be made of flame-retardant ABS (Acrylonitrile Butadiene Styrene) or PP (Polypropylene) materials. These materials have good mechanical strength, heat resistance (typically able to withstand temperatures above 80°C), and anti-aging properties.

[0046] Metal components, such as mounting frame 2, support frame 6, and locking parts 402, should be made of stainless steel (such as SUS304) or steel with surface anti-rust treatment (such as galvanizing or powder coating) to effectively resist moisture corrosion and extend service life.

[0047] For all screw connections, especially those near the heating module of the main unit 3, stainless steel screws should be used preferentially, and spring washers should be added where necessary to prevent the connection from loosening due to thermal expansion and contraction or vibration.

[0048] The installation process for this structure is detailed below.

[0049] 1. Preparation: First, disconnect the main power supply to the bathroom to ensure safe operation. Based on the dimensions of the main unit 3, precisely cut the panel opening 101 in the ceiling 1.

[0050] 2. Secure the mounting frame: Place the mounting frame 2 on the back of the ceiling 1, aligning its frame opening 201 with the board opening 101. Use self-tapping screws to pass through the fixing lugs of the mounting frame 2 and firmly secure it to the joists or reinforcing timber of the ceiling 1. Ensure that the mounting frame 2 is installed horizontally and securely.

[0051] 3. Pre-connecting the wiring: Lead the power cord, lighting cord, heating cord, etc. of the bathroom heater out from the main unit 3, pass through the frame opening 201, and reliably connect them to the corresponding wiring pre-embedded in the bathroom ceiling using terminal blocks, and ensure proper insulation.

[0052] 4. Install the main unit and air intake cover: Secure the air intake cover 5 to the air intake on the front surface of the main unit 3 with screws. Then install the support bracket 6 to the designated position on the front surface of the main unit 3 with screws.

[0053] 5. Hoisting the main unit: Carefully lift the main unit 3 with all components connected and insert it into the ceiling cavity through the opening 101. Lead the power cord of the main unit 3 out from the frame opening 201 of the mounting frame 2. Then, place the free end of the support frame 6 stably on the pre-prepared support wooden frame or keel.

[0054] 6. Connect the panel and the main unit: Connect the lead wire on the back of the panel 4 to the lead wire of the main unit 3 (usually a quick-connect plug). Then, manually adjust the position of the main unit 3 so that the top of the support bracket 6 is in good contact with the side surface of the air guide plate 406 on the back of the panel 4. At the same time, ensure that the opening end of the air intake shroud 5 on the main unit 3 is aligned with the air duct chamber on the back of the panel 4.

[0055] 7. Fixing the panel: Finally, align the panel 4 with the frame opening 201 of the mounting frame 2, and push it upwards to make the locking piece 402 on the edge of the panel 4 engage with the edge of the frame opening 201. A "click" sound indicates that the panel is in place.

[0056] 8. Functional test: Power on and test the lighting, heating, blowing, and ventilation functions of panel 4 in sequence. Observe whether the hinge 401 opens and closes normally and whether the fan makes any abnormal noise. After confirming that all functions are normal, the installation is complete.

[0057] In summary, this utility model creatively solves the long-standing technical problem of "double-layered airflow" in bathroom heaters through a precise docking design of the air intake hood, support frame, and air duct at the back of the panel. Its structure is reasonable, the installation process is clear, and it has high reliability, possessing significant practicality and commercial promotion value.

[0058] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
