Description

Technical Field

[0001] This invention relates to the field of hot water supply equipment, and more specifically, to an atomizing device and a gas water heater having the same. Background Technology

[0002] Instantaneous gas water heaters are widely used as common household hot water equipment due to their fast heating speed and clean water production. Since gas water heaters produce condensate during the heating process, they are usually equipped with a condensate drain pipe to discharge the condensate generated during the heating process to the outside of the gas water heater.

[0003] Existing condensate drain pipes are usually installed on the outside of gas water heaters, requiring specific installation locations to be reserved. This not only damages the overall appearance of the gas water heater but also limits its installation location, reducing its installation flexibility and applicability.

[0004] To address the aforementioned technical problems, existing technologies incorporate an atomizing device inside the gas water heater, with the atomized steam being directly discharged through the heater's flue. However, in existing atomizing devices, the condensate centrifuged by the centrifugal structure tends to splash everywhere, resulting in poor atomization efficiency. Summary of the Invention

[0005] The first technical problem solved by the present invention is to provide an atomizing device that can improve atomization efficiency.

[0006] The second technical problem solved by the present invention is to provide a gas water heater that avoids the problems of occupying the installation space of the gas water heater and affecting the appearance of the gas water heater caused by the external placement of the condensate drain pipe.

[0007] The first technical problem mentioned above is solved by the following technical solution:

[0009] Compared with the prior art, the atomizing device of this application has the following advantages: a forced water droplet transmission channel is formed between the centrifugal disc and the grid element through the guiding structure. This structure transforms the small water droplets after leaving the centrifugal disc from an uncontrollable splashing state to a controlled state of orderly movement within the guiding channel, thereby greatly reducing the possibility of small water droplets splashing into non-target areas and greatly increasing the number and uniformity of water droplets reaching the grid element, thus significantly increasing the atomization amount of condensate and improving atomization efficiency; in addition, the fan-shaped annular channel or the guiding channel of the annular channel can also ensure sufficient flow capacity.

[0010] In one embodiment, the guide structure includes an annular member and a connecting rib, the connecting rib connecting the annular member and the disc structure, and a guide channel formed between the lower surface of the annular member and the upper end surface of the disc structure.

[0011] In one embodiment, the guide channel has a first height dimension H1, and the grille has a second height dimension H2, wherein the ratio of the first height dimension H1 to the second height dimension H2 satisfies: 0.02≤H1 / H2≤0.6.

[0012] In one embodiment, the grid member has a second height dimension H2, and the ring member has a third height dimension H3, the ratio of the third height dimension H3 to the second height dimension H2 satisfies: 0.025≤H3 / H2≤1.2.

[0014] In one embodiment, when at least a portion of the upper end of the disc structure is recessed downward to form a guide groove, and the groove wall of the guide groove is an arc-shaped structure, the annular member extends from the edge of the guide groove toward the grid member to form an outer plate segment, and a guide channel is formed between the annular member and the guide groove, with the outlet of each guide channel facing the bottom surface of the outer plate segment.

[0015] In one embodiment, the minimum distance between the outer peripheral edge of the outer plate segment and the grid member is greater than or equal to 1 mm and less than or equal to 1.5 mm.

[0016] In one embodiment, the annular member extends from the edge of the guide groove toward the inside of the guide groove to form an inner plate segment.

[0017] In one embodiment, the disc structure, the ring-shaped component, the outer side plate segment, the inner side plate segment, and the connecting rib are formed into an integral structure.

[0018] In one embodiment, when at least a portion of the upper end of the disk structure is recessed downward to form a guide groove, and the groove wall of the guide groove is an arc-shaped surface structure, a plurality of guide ribs are provided on the guide groove. The plurality of guide ribs are arranged at intervals along the circumferential direction of the guide groove. Each guide rib extends from the center of the guide groove to the edge of the guide groove along a spiral trajectory, and the direction of the spiral trajectory is opposite to the rotation direction of the centrifugal disk.

[0019] In one embodiment, the atomizing hood further includes a top cover, the grid member has an upper opening, the top cover is disposed on the upper opening and connected to the grid member, and the atomizing device further includes a liquid delivery channel, the outlet of the liquid delivery channel is connected to the first centrifugal section, and the liquid delivery channel is disposed on the top cover.

[0020] In one embodiment, the atomizing cover further includes a top cover, a grid member having an upper opening, the top cover being disposed on the upper opening and connected to the grid member, and a drive member being a motor fixed on the upper side of the top cover, the motor's output shaft extending to the lower part of the top cover and connected to the centrifugal disc.

[0021] The second technical problem mentioned above is solved by the following technical solution:

[0022] A gas water heater includes a body, an atomizing device, and a fan. The atomizing device is disposed in the body and is used to atomize condensate in the body. The fan is used to blow the mist generated by the atomizing device out of the body. The atomizing device is the aforementioned atomizing device.

[0023] Compared with the prior art, the gas water heater of this application has the following advantages: The gas water heater of this application is equipped with an atomizing device inside the machine body. The condensate water is atomized inside the gas water heater and discharged through the flue, eliminating the need for an external drain pipe, making the overall appearance of the gas water heater more concise. By setting a guide structure in the atomizing device, the movement path of the condensate water leaving the centrifugal disc is controlled, so that it moves accurately to the grille, significantly increasing the amount of condensate water atomized and improving the atomization efficiency.

[0046] The technical solutions of 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 of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] When atomizing condensate in a gas water heater, a centrifugal disc is typically placed inside the atomizing hood. As the condensate passes the edge of the rotating disc, it initially forms small water droplets. These droplets then move with inertia and collide with the atomizing hood, further atomizing them. However, the droplets tend to splash when leaving the disc, resulting in low efficiency in further atomization. Therefore, to address these technical problems, this application provides an atomizing device.

[0048] Please refer to Figures 1 to 10This application provides an atomizing device, comprising: an atomizing hood 10, a centrifugal disc 20, and a driving component 30; the atomizing hood 10 includes a grid component 11; the centrifugal disc 20 is disposed inside the atomizing hood 10, the grid component 11 is located on the circumferential outer side of the centrifugal disc 20, the centrifugal disc 20 includes a disc body structure 21 and a guide structure 22 located above the disc body structure 21, the disc body structure 21 is rotatably disposed around its own axis, and a first centrifugal section 211 is disposed on the side of the disc body structure 21 facing the guide structure 22, the first centrifugal section 211... The outer peripheral edge is set towards the grid member 11, and the guide structure 22 is set at the outer peripheral edge of the first centrifugal part 211. The guide structure 22 has a guide channel 221 that penetrates the inner and outer surfaces of the guide structure 22. The first port of the guide channel 221 is connected to the first centrifugal part 211, and the second port of the guide channel 221 is set opposite to the grid member 11. The drive member 30 is connected to the centrifugal disk 20 and is used to drive the centrifugal disk 20 to rotate. The guide channel 221 is a fan-shaped annular channel extending along the circumferential direction of the guide structure 22.

[0049] The atomizing hood 10 is one of the components that enables secondary atomization of condensed water. The atomizing hood 10 includes a grid element 11, which is located on the outer circumferential side of the centrifugal disc 20, allowing secondary atomization to occur in the outer circumferential region of the centrifugal disc 20. As a key component for secondary atomization of condensed water, the circumferential arrangement of the grid element 11 ensures that water droplets ejected from the centrifugal disc 20 have ample opportunity to collide, while the gaps within the grid element 11 allow the secondary atomized condensed water to smoothly exit the atomizing device.

[0050] The drive unit 30 is connected to the centrifugal disk 20, which drives the centrifugal disk 20 to rotate at high speed around its own axis, providing centrifugal force to the condensed water, so that it can gain initial kinetic energy and be accelerated outward, thereby achieving atomization.

[0051] The centrifugal disc 20 is the core component for achieving primary atomization (initial centrifugal breakage). The centrifugal disc 20 includes a disc body structure 21 and a guide structure 22 located above the disc body structure 21. The disc body structure 21 serves as the mounting base for the other components of the centrifugal disc 20 and is also the basis for connection with the drive component 30. The disc body structure 21 is rotated by the drive component 30, causing the other components of the centrifugal disc 20 to move in the same way. A first centrifugal section 211 is provided on the side of the disc body structure 21 facing the guide structure 22, with its outer peripheral edge facing the grid component 11. When condensate is delivered to the first centrifugal section 211, under the centrifugal force generated by the high-speed rotation of the disc body structure 21, the condensate spreads outward and accelerates along the surface of the first centrifugal section 211. When it reaches the outer peripheral edge, it is broken into initial small water droplets due to its high linear velocity. At this time, the small water droplets tend to fly outward radially under the action of inertia. It should be noted that "the outer peripheral edge of the first centrifugal section 211 is set toward the grid member 11" means that after the water droplets leave the centrifugal disc 20, they move closer to the grid member 11 rather than away from the grid member 11.

[0052] To address the issue of uncontrollable splashing paths after water droplets detach, this embodiment incorporates a guide structure 22 located at the outer periphery of the first centrifugal section 211 on the centrifugal disc 20. The guide structure 22 has a guide channel 221 extending through its inner and outer surfaces. The first port of the guide channel 221 communicates with the first centrifugal section 211, while the second port is positioned opposite to the grid member 11. This structure creates a constrained path that limits the freedom of movement of the water droplets. Water droplets detaching from the outer periphery of the first centrifugal section 211 are captured by the first port and enter the guide channel 221 during the initial radial splashing phase. Constrained by the wall of the guide channel 221, the droplets are forced to move orderly along a predetermined spatial path, ultimately exiting from the second port in a directional and controllable manner, precisely spraying onto the grid member 11.

[0053] Therefore, in this embodiment, a forced water droplet transport channel is formed between the centrifugal disc 20 and the grid member 11 through the guide structure 22. This structure transforms the small water droplets after leaving the centrifugal disc 20 from an uncontrollable splashing state to a controlled state of orderly movement within the guide channel 221, thereby greatly reducing the possibility of small water droplets splashing into non-target areas and greatly increasing the number and uniformity of water droplets reaching the grid member 11, thus significantly increasing the atomization amount and atomization efficiency of the condensate.

[0054] Furthermore, compared to opening multiple discrete orifice channels on the guide structure 22, the fan-shaped annular channel provides a continuous and longer effective passage cross-section in the circumferential direction. When the drive unit 30 drives the disk structure 21 to rotate at high speed, a large number of small water droplets detached from the outer peripheral edge of the first centrifugal section 211 enter the guide channel 221 in a very short time. The fan-shaped annular channel, with its continuous circumferential space, can simultaneously accommodate and orderly guide more water droplets through, avoiding the water droplet congestion or backflow that may occur in orifice channels due to their scattered and limited circumferential space, thus ensuring smooth liquid flow at high speeds. Simultaneously, since the fan-shaped annular channel is a continuous opening area formed in the circumferential direction of the guide structure 22, the solid material of the guide structure 22 remains continuous in the circumferential direction while maintaining the same liquid flow rate, ensuring a certain connection strength characteristic. This structure achieves a balance between ensuring sufficient flow capacity and maintaining structural integrity, enabling the guide channel 221 to operate stably and reliably under high flow conditions.

[0055] In one embodiment, the guide channel differs from the fan-shaped annular channel in the above embodiment in that the guide channel 221 is an annular channel extending along the circumferential direction of the guide structure 22. In this embodiment, the guide structure 22 can be directly connected to the atomizing hood 10. That is, the guide structure 22 can rotate without following the rotation of the disc structure 21, but this does not affect the setting of the guide channel 221. In fact, due to the change in the connection method, the guide structure 22 can form a continuous annular channel, thereby maximizing the liquid throughput.

[0056] Please refer to Figures 1 to 10In one embodiment, the guide structure 22 includes an annular member 222 and a connecting rib 223. The connecting rib 223 connects the annular member 222 and the disc structure 21, and the guide channel 221 is formed between the lower surface of the annular member 222 and the upper end face of the disc structure 21. This configuration utilizes the axial clearance (i.e., vertical clearance) between the components of the centrifugal disc 20 to construct a liquid guiding path, resulting in a simple structure that is easy to manufacture. When the drive member 30 drives the disc structure 21 to rotate at high speed, the disc structure 21 rotates synchronously, and its first centrifugal section 211 centrifugally accelerates the condensate towards the outer periphery. Since the connecting rib 223 supports and fixes the annular member 222 above the disc structure 21, a circumferentially extending gap space is naturally formed between the lower surface of the annular member 222 and the upper end face of the disc structure 21, and this gap space constitutes the guide channel 221. As the small water droplets detach from the outer periphery of the first centrifugal section 211 move radially, they directly enter the constrained space enclosed by the upper and lower surfaces. Under the support and restraint of the lower surface of the annular component 222 and the upper surface of the disc structure 21, the splash trajectory of the water droplets is effectively constrained. They can only pass through the guide channel 221 along the preset path and finally be directionally ejected from the second port of the guide channel 221 to the grid component 11, completing precise collision atomization.

[0057] Meanwhile, the connecting ribs 223 act as a connecting structure between the annular component 222 and the disc structure 21. In one embodiment, multiple connecting ribs 223 are arranged at circumferential intervals to firmly fix the annular component 222 above the disc structure 21, so that the annular component 222 can maintain a precise spatial position and structural rigidity under the centrifugal force generated by high-speed rotation, avoiding changes in the gap size of the guide channel 221 due to vibration or deformation, and ensuring the stability of the water droplet's path.

[0058] In one embodiment, the cross-section of the connecting rib 223 can be configured as a streamlined cross-section shape, with an arc-shaped guide surface on the side facing the liquid flow direction. This allows small water droplets entering the guide channel 221 from the first centrifugal section 211 to be smoothly guided into the guide channel 221 when they come into contact with the connecting rib 223, preventing the formation of eddies or stagnant areas at the root of the connecting rib 223, and further improving the smoothness and uniformity of water droplets passing through the guide channel 221.

[0059] In one embodiment, the guide channel 221 has a first height dimension H1, and the grid member 11 has a second height dimension H2. The ratio of the first height dimension H1 to the second height dimension H2 satisfies: 0.02 ≤ H1 / H2 ≤ 0.6. This numerical relationship is set to balance the liquid throughput and the guiding effect. When the ratio of H1 / H2 is within the defined range, the guide channel 221 has sufficient axial height to accommodate a large number of small water droplets detached from the outer peripheral edge of the first centrifugal part 211 and allow them to pass smoothly. If the ratio is too small, i.e., H1 is too small relative to H2, the cross-sectional area of ​​the guide channel 221 is limited. When the drive member 30 drives the disc structure 21 to rotate at high speed to generate a large flow of liquid, the water droplets may become congested due to the narrow channel, causing some water droplets to overflow from a non-preset direction, thus weakening the guiding effect. If the ratio is too large, the axial height of the guide channel 221 will be too large, resulting in an excessively loose constraint space between the lower surface of the annular component 222 and the upper surface of the disk structure 21. This increases the axial movement freedom of the water droplets within the channel, potentially causing vertical jumping or vortex disturbances. This also leads to directional divergence when detaching from the second port, reducing the accuracy of the water droplets hitting the grid component 11. The ratio H1 / H2 of the first height dimension H1 to the second height dimension H2 can be 0.02, 0.08, 0.1, 0.15, 0.23, 0.38, 0.4, 0.57, or 0.6. More specifically, the first height dimension H1 is greater than or equal to 0.8 mm and less than or equal to 3 mm; the second height dimension H2 is greater than or equal to 5 mm and less than or equal to 40 mm.

[0060] In one embodiment, the grille 11 has a second height dimension H2, and the annular member 222 has a third height dimension H3. The ratio of the third height dimension H3 to the second height dimension H2 satisfies: 0.025 ≤ H3 / H2 ≤ 1.2. This numerical relationship is set to balance the water-blocking effect with the overall weight and cost of the atomizing device. The third height dimension H3 of the annular member 222 directly determines the axial coverage range of the solid material above the guide channel 221. When the ratio of H3 / H2 is within the defined range, the annular member 222 has sufficient height to confine all the liquid in the guide channel 221 within the effective collision area of ​​the grille 11, that is, the annular member 222 can play a water-blocking role. If the ratio is too small, that is, H3 is too small relative to H2, the axial water-blocking coverage of the annular member 222 is insufficient. The initial water droplets detached from the first centrifugal part 211 may escape due to inertia and jump upwards out of the confinement range of the annular member 222, resulting in a decrease in the water-blocking effect and a reduction in the number and hit rate of water droplets guided to the grille 11. If the ratio is too large, the annular component 222 will be too tall. While this enhances the water-blocking effect, it also increases the weight and material usage of the annular component 222, increasing the rotational inertia of the centrifugal disc 20 and the power requirement for the drive component 30, thus raising manufacturing costs. Within a reasonable H3 / H2 ratio range, the annular component 222 provides sufficient axial water-blocking constraint, ensuring all water droplets smoothly enter the grid component 11, while minimizing material consumption and component weight, achieving an effective balance between water-blocking effect and the overall weight and cost of the atomizing device. The ratio H3 / H2 of the third height dimension H3 to the second height dimension H2 can be 0.025, 0.05, 0.12, 0.18, 0.34, 0.58, 0.76, 0.8, 1, 1.15, or 1.2. More specifically, the third height dimension H3 is greater than or equal to 1 mm and less than or equal to 6 mm.

[0061] Please refer to Figures 1 to 10In one embodiment, the first centrifugal section 211 is the upper end face of the disc structure 21. At least a portion of the upper end face of the disc structure 21 is recessed downwards to form a guide groove 212, and the groove wall of the guide groove 212 has an arc-shaped surface structure. When the drive member 30 drives the disc structure 21 to rotate, and condensate is transported to the upper end face of the disc structure 21, the presence of the guide groove 212 provides a predetermined space for liquid to converge and guide. The downwardly recessed guide groove 212 can actively collect and accommodate the liquid entering the area, preventing the liquid from flowing disorderly or splashing prematurely along the upper end face due to lack of constraint in the early stage of high-speed rotation, ensuring that the liquid is effectively converged and guided in an orderly manner. More importantly, the groove wall of the guide groove 212 is constructed as an arc-shaped surface structure. This curved shape makes the change in the flow direction of the liquid continuous and smooth when it moves from the inside to the outside along the groove wall under the action of centrifugal force. The curved surface avoids localized eddies, impacts, or energy scattering caused by sharp corners or abrupt changes in cross-section along the liquid's flow path, minimizing irregular breakage caused by self-collision or impact with the wall during the guiding stage. Guided by the curved groove wall, the liquid arrives smoothly at the outer edge of the first centrifugal section 211 in a more concentrated state and at a higher speed, providing sufficient conditions for subsequent entry into the guide channel 221 and achieving a uniform and stable initial centrifugal breakage effect, thereby improving atomization efficiency.

[0062] In one embodiment, the first centrifugal section 211 is the upper end face of the disc structure 21, and the upper end face of the disc structure 21 is a first planar structure. The first planar structure has significant advantages from a manufacturing process perspective. The planar structure eliminates the need for complex milling or forming processes, resulting in simpler processing, lower manufacturing costs, and easier control over dimensional accuracy and surface quality. In mass production, the first planar structure can achieve stable and reliable part production with higher processing efficiency and lower scrap rates.

[0063] Please refer to Figures 1 to 10 The centrifuge disc 20 also includes a guide cone 23, and the atomizing hood 10 also includes a liquid storage chamber 12. The liquid storage chamber 12 is located below the grid member 11. A second centrifuge part 213 is provided on the side of the disc structure 21 away from the guide structure 22. The guide cone 23 is provided on the side of the disc structure 21 away from the guide structure 22. The outer peripheral edge of the second centrifuge part 213 is provided towards the grid member 11. The guide surface of the guide cone 23 is connected to the second centrifuge part 213. At least a portion of the guide cone 23 extends into the liquid storage chamber 12.

[0064] A second centrifugal section 213 is added to the lower side of the disc structure 21 away from the guide structure 22, creating a lower liquid centrifugal atomization path independent of the upper first centrifugal section 211. The liquid storage chamber 12 enables the atomizing hood 10 to temporarily store condensate below the grid member 11. When a certain amount of condensate accumulates in the liquid storage chamber 12, the guide cone 23, which extends at least partially into the liquid storage chamber 12, can directly contact the liquid surface. When the drive member 30 drives the disc structure 21 to rotate at high speed, the guide cone 23 rotates synchronously. Utilizing the centrifugal pumping effect generated by its conical surface, the condensate in the liquid storage chamber 12 is lifted upwards along the outer surface of the guide cone 23 and transported to the second centrifugal section 213. This structure enables the centrifugal disc 20 to actively draw liquid from the liquid storage chamber 12, without relying on an additional pumping device or the liquid's own gravity overflow. After the liquid enters the second centrifugal section 213 through the guide cone 23, it spreads outward along the surface of the second centrifugal section 213 and accelerates under the action of centrifugal force. When it reaches the outer peripheral edge of the second centrifugal section 213, the liquid is first centrifuged and broken into initial small water droplets, which are then sprayed directly towards the grid member 11 under the action of inertia. Since the outer peripheral edge of the second centrifugal section 213 is set towards the grid member 11, the direction of the water droplets' departure corresponds directly in space to the collision area of ​​the grid member 11. It should be noted that "the outer peripheral edge of the second centrifugal section 213 is set towards the grid member 11" means that the water droplets move closer to the grid member 11 after leaving the centrifugal disk 20, rather than moving away from the grid member 11. This configuration allows the centrifugal disc 20 to have centrifugal atomization capabilities on both the upper and lower sides. The upper side processes the liquid from above through the first centrifugal section 211 and the guide structure 22, while the lower side processes the liquid accumulated in the storage chamber 12 through the guide cone section 23 and the second centrifugal section 213. The double-sided centrifugal layout significantly improves the liquid processing capacity and overall atomization efficiency of the atomization device.

[0065] Please refer to Figures 1 to 10In one embodiment, the second centrifugal section 213 is the lower end face of the disc structure 21. The lower end face of the disc structure 21 includes a flat wall surface 214 and an inclined wall surface 215 connected from the inside to the outside. The inclined wall surface 215 slopes downward in the direction from the inside to the outside and forms the outer peripheral edge of the second centrifugal section 213. The guide cone 23 is located inside the flat wall surface 214. This segmented end face configuration optimizes the complete path of the liquid moving from the guide cone 23 to the grid member 11. When the guide cone 23 lifts and delivers the condensate in the liquid storage chamber 12 to the second centrifugal section 213, the liquid first enters the region of the flat wall surface 214 located on the inside. The flat wall surface 214 provides a smooth initial receiving surface for the liquid, in which the liquid completes the transition from the axial lifting motion of the guide cone 23 to the radial centrifugal motion, avoiding splashing or energy loss caused by abrupt changes in the direction of movement. Subsequently, under the action of centrifugal force, the liquid continues to move outward from the flat wall 214 region and enters the inclined wall 215. The downward slope of the inclined wall 215 causes it to gradually decrease in the direction from the inside to the outside. As the liquid moves along this inclined surface, it is simultaneously subjected to the combined effect of centrifugal force and the component of gravity along the inclined surface, resulting in a more significant acceleration. The liquid gains a higher radial velocity on the inclined wall 215. When it reaches the outer peripheral edge of the second centrifugal section 213 formed at the end of the inclined wall 215, the liquid is thrown out with higher kinetic energy, forming finer initial water droplets, and is sprayed towards the grid member 11 along the downward sloping departure direction.

[0066] In one embodiment, the second centrifugal section 213 is the lower end face of the disc structure 21, and the lower end face of the disc structure 21 is a second planar structure. The second planar structure has significant advantages in terms of manufacturing process. The single planar structure does not require angle forming processing; it can be completed by turning or grinding, resulting in a simple and efficient process route, and easy assurance of machining accuracy and surface quality.

[0067] Please refer to Figures 1 to 10 In one embodiment, the atomizing device further includes a liquid delivery channel 40, which includes a main channel 41, a first sub-branch channel 42, and a second sub-branch channel 43. The first sub-branch channel 42 and the second sub-branch channel 43 are located inside the atomizing hood 10. The first end of the first sub-branch channel 42 is connected to the main channel 41, and the second end of the first sub-branch channel 42 is connected to the liquid storage chamber 12. The first end of the second sub-branch channel 43 is connected to the main channel 41, and the second end of the second sub-branch channel 43 is connected to the first centrifugal section 211.

[0068] This branched liquid supply structure allows condensate from a single input to be simultaneously distributed to the upper and lower working areas of the centrifugal disc 20. The main channel 41, serving as the main inlet for liquid delivery, introduces condensate into the atomizing hood 10. The first sub-branch channel 42 then directly delivers a portion of the liquid to the storage chamber 12 located below the grid member 11 for temporary storage, providing liquid reserves for the lower centrifugal atomization paths of the guide cone 23 and the second centrifugal section 213. Simultaneously, the second sub-branch channel 43 directly delivers another portion of the liquid to the first centrifugal section 211 on the upper surface of the disc structure 21, directly supplying liquid to the upper centrifugal atomization paths of the first centrifugal section 211 and the guide structure 22. This dual-path parallel liquid supply allows the centrifugal atomization functions on both the upper and lower sides of the centrifugal disc 20 to operate simultaneously, fully utilizing the double-sided centrifugal capacity of the centrifugal disc 20 and significantly increasing the overall liquid processing capacity of the atomizing device. Furthermore, the two sub-branch channels correspond to different liquid supply methods. The liquid supplied to the storage chamber 12 by the first sub-branch channel 42 is supplied via immersion. The guide cone 23 draws liquid from the storage chamber 12 by self-priming, resulting in a relatively slow and stable supply speed. The second sub-branch channel 43, on the other hand, directly supplies liquid to the surface of the high-speed rotating first centrifugal section 211. Upon contact, the liquid is rapidly spread by centrifugal force, resulting in a fast response. The two supply methods complement each other, giving the atomizing device good adaptability to rate fluctuations caused by condensate. The outlet of the liquid delivery channel 40 is the second end of the second sub-branch channel 43. Of course, the liquid delivery channel 40 also has other outlets.

[0069] Please refer to Figures 1 to 10 In one embodiment, the atomizing hood 10 further includes a top cover 13. The grid member 11 has an upper opening, and the top cover 13 is placed over the upper opening and connected to the grid member 11. A liquid delivery channel 40 is disposed on the top cover 13. The top cover 13 closes the upper opening of the grid member 11, forming a structurally complete closed cavity at the top of the atomizing hood 10. When the disc structure 21 rotates at high speed to centrifuge and break up the condensate and spray it onto the grid member 11 for secondary atomization, some water droplets may splash or bounce upwards after colliding with the grid member 11, thereby avoiding impact on other components such as the drive member 30 and preventing wetting and contamination of surrounding components. By directly placing the liquid delivery channel 40 on the top cover 13, the liquid supply path is integrated with the structural function of the top cover 13, thereby optimizing the structural layout.

[0070] Please refer to Figures 1 to 10 In one embodiment, the drive component 30 is a motor, which is fixed on the upper side of the top cover 13, and the output shaft of the motor extends to the lower part of the top cover 13 and is connected to the centrifugal disc 20.

[0071] The motor is directly fixed to the upper side of the top cover 13, and its output shaft runs from top to bottom through the top cover 13 and connects directly to the centrifugal disc 20 located inside the atomizing cover 10. The driving torque is directly transmitted from the motor output shaft to the rotation axis of the disc structure 21, resulting in high transmission efficiency and low loss, ensuring the rotational accuracy and operational stability of the disc structure 21 at high speeds. The motor's installation position is also rationally organized. The top cover 13 serves as an open structural component covering the grille 11, and the motor is fixed to it, eliminating the need for additional motor supports on the sides or bottom of the atomizing cover 10, thus simplifying the overall structure of the atomizing cover 10. The motor is positioned in the space above the top of the atomizing cover 10, effectively utilizing the space above the atomizing cover 10 and avoiding spatial conflicts with other components.

[0072] In addition, please refer to Figures 1 to 10 In one embodiment, a weight-reducing annular groove 24 is also provided at the circumferential edge of the disc structure 21, located between the first centrifugal section 211 and the second centrifugal section 213. The weight-reducing annular groove 24 directly reduces the overall weight and moment of inertia of the centrifugal disc 20. By creating an annular groove at the circumferential edge between the first centrifugal section 211 and the second centrifugal section 213, edge solid material that contributes little to the centrifugal function but has a significant impact on the moment of inertia is selectively removed. This significantly reduces the acceleration and deceleration torque required for the drive component 30 to start and stop the centrifugal disc 20, resulting in faster motor response and more economical energy consumption.

[0073] In addition, please refer to Figure 11 as well as Figure 12 In one embodiment, when at least a portion of the upper end of the disc structure 21 is recessed downwards to form a guide groove 212, and the groove wall of the guide groove 212 is an arc-shaped structure, the annular member 222 extends from the edge of the guide groove 212 toward the grid member 11 to form an outer plate segment 53. A guide channel 221 is formed between the annular member 222 and the guide groove 212, with the outlet of each guide channel 221 facing the bottom surface of the outer plate segment 53. The annular member 222 extends from the edge of the guide groove 212 toward the inner side of the guide groove 212 to form an inner plate segment 52. The minimum distance between the outer peripheral edge of the outer plate segment 53 and the grid member 11 is greater than or equal to 1 mm and less than or equal to 1.5 mm. The disc structure 21, the annular member 222, the outer plate segment 53, the inner plate segment 52, and the connecting rib 223 are formed as a single integral structure.

[0074] In this way, the inner plate segment 52 and the outer plate segment 53 together form part of the annular component 222. The inner plate segment 52 extends radially into the guide groove 212, forming an annular blocking structure. During the rotation of the centrifugal disc 20, this structure prevents condensate from being thrown out of the guide groove 212 in a non-designed direction (e.g., splashing inwards and upwards), instead directing it to move along the guide channel 221. When the condensate accumulates in the tank under the protection of the baffle 51, it is guided by the guide channel 221 and the outer plate segment 53 and then thrown towards the grid component 11. This ensures controllable condensate flow and release position, preventing uneven distribution caused by random dripping and resulting atomization fluctuations, thus improving atomization stability. The minimum distance between the outer peripheral edge of the outer plate segment 53 and the grid component 11 is greater than or equal to 1 mm and less than or equal to 1.5 mm, allowing the thrown liquid to quickly impact the grid component 11 for atomization. If the distance is too small, the outer plate segment 53 and the grid member 11 are prone to collision due to vibration during operation, which will affect the structural strength. If the distance is too large, the flow path of condensate on the outer plate segment 53 will be reduced, and some condensate may fall under its own weight before hitting the grid member 11, which will affect the atomization efficiency.

[0075] Please refer to Figure 13 In one embodiment, a plurality of guide ribs 55 are provided on the guide groove 212. The plurality of guide ribs 55 are arranged at intervals along the circumferential direction of the guide groove 212. Each guide rib 55 extends from the center of the guide groove 212 to the edge of the guide groove 212 along a spiral trajectory. The direction of the spiral trajectory is opposite to the rotation direction of the centrifugal disk 20.

[0076] Thus, with the guide ribs 55 in place, when condensate enters the guide groove 212, the water gathers towards the bottom of the groove under gravity. The spiral structure of the guide ribs 55 guides the water flow along its surface towards the edge, preventing water from stagnating in the central area or forming eddies. Since the spiral trajectory is opposite to the rotation direction of the centrifugal disk 20, the water flow is simultaneously propelled by centrifugal force as it flows along the guide ribs 55, ensuring that the water film forms a uniform, thin layer before reaching the edge of the guide groove 212. This ensures that the condensate has a consistent flow velocity and distribution before being ejected, improving the uniformity and stability of the water film tearing. The guide ribs 55 also reduce the non-directional diffusion of water flow within the groove caused by surface tension or local viscosity, reducing the risk of random splashing or local accumulation of water droplets, making the atomization process more controllable. At the same time, the structure of the guide ribs 55 enhances structural rigidity, reduces deformation caused by vibration during high-speed rotation, and improves the structural reliability during long-term operation.

[0077] The present invention also provides a gas water heater, including a body 1, an atomizing device and a fan 2. The atomizing device is disposed inside the body 1 and is used to atomize the condensate inside the body 1. The fan 2 is used to blow the mist generated by the atomizing device out of the body 1. The atomizing device is the atomizing device described above.

[0078] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0079] An atomizing device is installed inside the unit, so the condensate is atomized inside the gas water heater and discharged through the flue, eliminating the need for an external drain pipe and making the overall appearance of the gas water heater more concise. By setting a guide structure in the atomizing device, the movement path of the condensate leaving the centrifugal disc is controlled, so that it moves precisely to the grille, significantly increasing the amount and efficiency of condensate atomization.
