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] Gas-fired instantaneous water heaters are widely used as common household hot water equipment due to their fast heating speed and clean water production. Since gas-fired 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 water heater.

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

[0004] To address the aforementioned technical issues, existing technologies incorporate an atomizing device inside the water heater, with the atomized steam being directly discharged through the heater's flue. However, existing atomizing devices require high-quality surface coating materials, limiting the flow rate of condensate water in a single atomization cycle and reducing 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 water heater and affecting the appearance of the 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:

[0008] Atomizing device includes: a plurality of covers arranged in a vertical direction, each cover including a bottom shell and a grid structure, the bottom shell having a water storage cavity, and the grid structure connected to the top of the bottom shell; rotating components corresponding to each cover, the rotating components being rotatably disposed within the cover about their own axis, the rotating components including a guide cone and a centrifugal disc connected in sequence, at least a portion of the guide cone being located within the water storage cavity, and the outer peripheral edge of the centrifugal disc being disposed opposite to the grid structure; and a driving component connected to each rotating component to drive each rotating component to rotate.

[0009] Compared with the prior art, the atomizing device of the present invention has the following advantages:

[0010] Multiple enclosures are arranged sequentially in a vertical direction. Each atomization stage consists of a centrifugal disc and a grid structure. The upper centrifugal disc and the upper grid structure are opposite each other to process the condensate dripping into the upper water storage chamber, forming the first stage of atomization. The lower centrifugal disc and the lower grid structure are opposite each other to process the condensate dripping into the lower water storage chamber, forming the second stage of atomization, and so on. Since the water storage chambers of each enclosure have independent water inlet, there is no droplet backflow, and the atomization process is uninterrupted between each stage. Each stage of atomization only acts on the condensate of its own stage, achieving parallel multi-point atomization. This multi-stage independent atomization structure improves the atomization efficiency of condensate, has a compact structure, stable operation, and no risk of water accumulation, solving the problem of low atomization efficiency in existing gas water heaters.

[0011] In one embodiment, the output shaft of the drive unit is sequentially inserted into each housing from top to bottom and is fixedly connected to each rotating component.

[0012] In one embodiment, the plurality of covers include at least one first cover and one second cover, with the second cover located below at least one first cover; wherein, the bottom shell of each first cover is provided with a clearance hole for the output shaft of the drive component to pass through, and a water-retaining ring is provided around the clearance hole.

[0013] In one embodiment, the bottom of the drainage cone within each first enclosure is provided with an avoidance groove, and the top of the water-blocking ring is located within the avoidance groove.

[0014] In one embodiment, the plurality of covers include a first cover located at the top, the first cover having an upper opening, and an upper cover covering the upper opening; the drive component is a motor, the motor's base is fixed to the outer wall of the upper cover, and the motor's output shaft passes through the upper cover and is fixedly connected to each rotating component.

[0015] In one embodiment, each cover is provided with a first condensate delivery channel, which is connected to the corresponding water storage chamber.

[0016] In one embodiment, the plurality of covers include a first cover located at the top, the first cover having an upper cover, a drive member disposed on the outer wall of the upper cover, the output shaft of the drive member passing through the upper cover and fixedly connected to each rotating component; wherein, the upper cover is provided with a plurality of second condensate delivery channels, each second condensate delivery channel corresponding to and connected to each first condensate delivery channel.

[0017] In one embodiment, two adjacent covers are fixedly connected by a bracket; or, two adjacent covers are interconnected.

[0018] In one embodiment, the plurality of covers include a first cover and a second cover arranged sequentially in a vertical direction. The top of the first cover is connected to a top cover, and a drive member is disposed on the outer wall of the top cover. The output shaft of the drive member passes through the top cover and is fixedly connected to each rotating component. The second cover is fixedly connected to the top cover by a bracket.

[0019] In one embodiment, the second cover is provided with a first condensate delivery channel, which is connected to the water storage chamber; the upper cover is provided with a second condensate delivery channel; and the bracket is provided with a third condensate delivery channel, the two ends of which are connected to the second condensate delivery channel and the first condensate delivery channel, respectively.

[0020] According to another aspect of the present invention, a gas water heater is provided, comprising a body, an atomizing device, and a fan. The atomizing device is disposed within the body, and the fan is disposed above the atomizing device. The air inlet of the fan faces the atomizing device, and the air outlet of the fan faces the outside of the body. The atomizing device is the aforementioned atomizing device.

[0021] Compared with the prior art, the gas water heater of the present invention has the following advantages: the atomizing device is integrated inside the body to optimize the atomization and discharge process of condensate. The atomizing device is located between the combustion chamber and the flue, so that the atomized condensate can be discharged through the flue along with the flue gas without affecting the combustion process or heat exchange efficiency. There is no need for an external drain pipe, making the overall appearance of the water heater simpler. Attached Figure Description

[0035] 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.

[0036] When atomizing condensate in a gas water heater, the condensate is typically drawn into the intake body via a reverse suction method. Centrifugal force then propels the condensate outwards. Upon contact with the grid structure, the impact disperses the water droplets, achieving atomization. However, existing atomizing devices can only atomize a fixed amount of condensate; excessive condensate can easily overflow from the device, resulting in low atomization efficiency. Therefore, to address these technical problems, this application provides an atomizing device.

[0037] refer to Figures 1 to 4 This application provides an atomizing device, comprising: a plurality of covers 100 arranged in a vertical direction, each cover 100 including a bottom shell 110 and a grid structure 120, the bottom shell 110 having a water storage cavity 111, and the grid structure 120 being connected above the bottom shell 110; rotating components 200 corresponding to each cover 100, the rotating components 200 being rotatably disposed within the cover 100 about their own axis, the rotating components 200 including a guide cone 210 and a centrifugal disc 220 connected in sequence, at least a portion of the guide cone 210 being located within the water storage cavity 111, and the outer peripheral edge of the centrifugal disc 220 being disposed opposite to the grid structure 120; and a driving member 300 connected to each rotating component 200 to drive each rotating component 200 to rotate.

[0038] The covers 100 of this application are arranged sequentially in the vertical direction. Each cover 100 is an independent structure, including a bottom shell 110 and a grid structure 120. A water storage cavity 111 is formed inside the bottom shell 110, which receives condensate dripping from the heat exchanger.

[0039] The grid structure 120 is connected above the bottom shell 110. The grid structure 120 is opposite to the outer peripheral edge of the centrifugal disk 220 of the corresponding rotating component 200 to form an independent atomization working area. The grid structure 120 is used to receive the droplets thrown out by the centrifugal disk 220 and break them by impact to form mist droplets.

[0040] The drive component 300 (such as a motor) is installed at the bottom center of the cover 100, and its output shaft is connected to the rotating component 200 through a water-resistant sealed bearing to ensure that the rotating component 200 can operate reliably for a long time in a humid environment.

[0041] Each rotating component 200 corresponds to one of the housings 100. The rotating component 200 includes a flow-guiding cone 210 and a centrifugal disc 220, which are integrally formed to ensure structural stability at high speeds. The flow-guiding cone 210 is an inverted cone shape, with its bottom immersed below the liquid surface of the water storage chamber 111. The localized negative pressure generated by rotation, combined with the surface tension of the liquid, allows the condensate to move smoothly upwards along the cone surface, achieving self-priming liquid supply without external pumping. The centrifugal disc 220 is located above the flow-guiding cone 210. When the rotating component 200 rotates, the liquid is driven by centrifugal force to diffuse radially along the disc surface, impacting the grid structure 120 at high speed. The liquid film is torn into fine droplets, achieving atomization.

[0042] Multiple enclosures 100 are arranged sequentially in a vertical direction. Each atomization stage is formed by a centrifugal disc 220 and a grid structure 120. The upper centrifugal disc 220 and the upper grid structure 120 are opposite each other to process the condensate dripping into the upper water storage chamber 111, forming the first stage of atomization. The lower centrifugal disc 220 and the lower grid structure 120 are opposite each other to process the condensate dripping into the lower water storage chamber 111, forming the second stage of atomization, and so on. Since the water storage chamber 111 of each enclosure 100 is independently inlet, there is no droplet backflow, and the atomization process is uninterrupted between stages. Each stage of atomization only acts on the condensate of its own stage, achieving parallel multi-point atomization. This multi-stage independent atomization structure improves the atomization efficiency of condensate, has a compact structure, stable operation, and no risk of water accumulation, solving the problem of low atomization efficiency in existing gas water heaters.

[0043] Specifically, such as Figure 2 As shown, multiple covers 100 are arranged sequentially in the vertical direction, and the output shaft of the drive component 300 passes through each cover 100 from top to bottom and is fixedly connected to each rotating component 200.

[0044] In this way, multiple enclosures 100 are arranged sequentially in the vertical direction. Each enclosure 100 contains an independent rotating component 200, which includes a guide cone 210 and a centrifugal disc 220. The axial center of the rotating component 200 coincides with the axis of the enclosure 100. The drive shaft of the drive unit 300 passes through the central area of ​​all enclosures 100 from top to bottom and is directly fixedly connected to the central shaft hole of each rotating component 200, forming a rigid transmission. This ensures that there is no radial interference when each rotating component 200 rotates, and that multiple rotating components 200 are driven by a single drive unit 300. This avoids the problems of space occupation, complex wiring, and inconsistent control caused by multiple motor arrangements. At the same time, each rotating component 200 is accurately positioned axially by the drive unit 300, and the relative position of the centrifugal disc 220 and the corresponding grid structure 120 remains stable, ensuring uniform droplet impact efficiency in each atomization process. The overall transmission structure simplifies the mechanical assembly process and improves the manufacturing consistency and operational reliability of the device.

[0045] In the specific implementation process, such as Figure 2 As shown, the plurality of covers 100 include at least one first cover 130 and one second cover 140, with the second cover 140 located below at least one first cover 130; wherein, each first cover 130 has a clearance hole 112 on its bottom shell 110 for the output shaft of the drive member 300 to pass through, and a water baffle ring 113 is provided around the clearance hole 112.

[0046] Each of the first covers 130 has a clearance hole 112 at the center of the bottom shell 110 for the output shaft of the drive component 300 to pass through. A water baffle ring 113 is integrally formed around the clearance hole 112. The water baffle ring 113 protrudes upward and its height is higher than the highest liquid level of the water storage cavity 111 inside the bottom shell 110.

[0047] When the drive unit 300 rotates, the water-blocking ring 113 prevents droplets from overflowing along the outer edge of the clearance hole 112 through its enclosure structure, ensuring that the water storage chamber 111 of each first cover 130 can stably store liquid and prevent liquid cross-flow due to the rotation of the drive unit 300. This structure achieves the anti-overflow function of the shaft hole area by utilizing the molding structure of the bottom shell 110 itself without adding additional seals, improving assembly reliability and ensuring that the atomization process of each first cover 130 is independent and stable.

[0048] Specifically, such as Figure 2 As shown, the bottom of the drainage cone 210 in each of the first covers 130 is provided with a relief groove 211, and the top of the water-blocking ring 113 is located in the relief groove 211.

[0049] The clearance groove 211 is an axially recessed structure, and its depth matches the height of the water-blocking ring 113. After assembly, the top of the water-blocking ring 113 is inserted into the clearance groove 211. The inner diameter of the clearance groove 211 is slightly larger than the outer diameter of the water-blocking ring 113, and a small gap is maintained between them. This ensures that the drainage cone 210 can rotate freely with the rotating component 200 without interfering with the water-blocking ring 113. During the rotation process, the lower end of the drainage cone 210 is kept at a stable depth immersed in the liquid surface of the water storage chamber 111, ensuring the continuity of liquid self-priming supply.

[0050] Meanwhile, after at least a portion of the water-retaining ring 113 is inserted into the clearance groove 211, its upper end face forms a smooth transition with the bottom surface of the drainage cone 210, preventing droplets from accumulating at the edge of the water-retaining ring 113 or climbing axially. This fitting method achieves the overflow prevention function through structural fitting without adding sealing elements, improving assembly accuracy and operational stability, and ensuring that the atomization process of each stage's first cover 130 is independent and reliable, unaffected by interference from other structural levels.

[0051] In this application, as Figure 2 As shown, the plurality of covers 100 include a first cover 130 located at the top, the first cover 130 having an upper opening, and an upper cover 400 covering the upper opening; the driving component 300 is a motor, the motor's base is fixed to the outer wall of the upper cover 400, and the motor's output shaft passes through the upper cover 400 and is fixedly connected to each rotating component 200.

[0052] The upper opening fits tightly against the lower surface of the upper cover 400, isolating the internal rotating component 200 from the water storage chamber 111 and thus enclosing the atomizing area. The drive component 300 is a motor, whose base is directly fixed to the outer wall surface of the upper cover 400 by bolts or snap-fit ​​structures. Located in the external space above the atomizing area, it does not directly contact the interior of the cover 100 or the inner cavity of the upper cover 400, ensuring that the motor body is completely in the external environment of the atomizing device and physically isolated from the internal high-humidity, high-concentration mist droplet operating area. This arrangement effectively avoids the direct impact of a humid environment on the motor's insulation performance and corrosion of metal components, reduces the risk of short circuits, torque attenuation, or bearing jamming caused by moisture intrusion, extends service life, improves the overall reliability of the system, and eliminates the need for additional moisture-proof covers or drying devices.

[0053] In the specific implementation process, such as Figure 2 As shown, each cover 100 is provided with a first condensate delivery channel 101, which is connected to the corresponding water storage chamber 111.

[0054] The first condensate delivery channel 101 is an independently perforated flow channel structure, directly connecting the condensate collection area of ​​the heat exchanger outside the enclosure 100 with the water storage chamber 111 inside the enclosure 100. Under the action of gravity, the condensate flows naturally into the corresponding water storage chamber 111 along the first condensate delivery channel 101. Each channel serves only one enclosure 100 and is not connected to the water storage chambers 111 of other enclosures 100, allowing the condensate to be delivered according to location and ensuring that each water storage chamber 111 only receives condensate dripping from the heat exchanger area, achieving precise distribution and independent reception of condensate. Since each delivery channel corresponds one-to-one with the water storage chamber 111, internal mixing or overflow of condensate is avoided, ensuring a stable water intake for each atomizing unit, providing a continuous and controllable liquid supply to the centrifugal disc 220, and improving the consistency of atomization efficiency and the stability of system operation.

[0055] Specifically, such as Figure 2 As shown, the plurality of covers 100 include a first cover 130 located at the top, the first cover 130 is covered with an upper cover 400, a drive member 300 is disposed on the outer wall of the upper cover 400, and the output shaft of the drive member 300 passes through the upper cover 400 and is fixedly connected to each rotating component 200; wherein, the upper cover 400 is provided with a plurality of second condensate conveying channels 401, and each second condensate conveying channel 401 is connected to each first condensate conveying channel 101 in a one-to-one correspondence.

[0056] The upper cover 400 is equipped with multiple second condensate delivery channels 401, each extending vertically downwards and directly connected to the first condensate delivery channel 101 of the corresponding lower cover 100, forming an independent water supply path from the outside of the upper cover 400 to each water storage chamber 111. Each second condensate delivery channel 401 corresponds one-to-one with the first condensate delivery channel 101, ensuring that condensate is accurately distributed to each cover 100 according to its location. This allows the condensate generated by the heat exchanger to be uniformly accessed from the upper cover 400, avoiding water vapor leakage or structural weakness caused by openings around the atomization area. Each delivery channel is independently connected, ensuring a clear and non-intersecting water inlet path for each water storage chamber 111, stable condensate supply, controllable atomization volume, and improved system operational consistency.

[0057] In one embodiment where two adjacent covers 100 are assembled, such as Figure 2 As shown, two adjacent covers 100 are fixedly connected by a bracket 500.

[0058] The bracket 500 is a rigid structural component. Its two ends are connected to the upper and lower covers 100 respectively, forming axial positioning and limiting, ensuring that adjacent covers 100 maintain a fixed vertical distance. This prevents relative displacement of each cover 100 during operation due to vibration, thermal expansion, or liquid weight, maintaining a precise clearance between the internal rotating parts 200 and the atomizing cover. This structure ensures stable coaxiality between the output shaft of the drive unit 300 and each rotating part 200, avoiding increased rotational resistance, axial movement, or localized wear caused by cover 100 misalignment. Simultaneously, the bracket 500 transfers the load from one cover 100 to the other, achieving mechanical synergy of the overall structure, improving overall rigidity, and reducing localized stress concentration. The independent atomization function of each cover 100 is unaffected by the displacement of adjacent components, ensuring uniform atomization volume and consistent particle fineness, thus improving system operational stability and long-term reliability.

[0059] In another embodiment where two adjacent covers 100 are assembled, the two adjacent covers 100 are interconnected.

[0060] The two adjacent covers 100 are assembled via a direct connection structure. Their contact surfaces are connected as a whole through a fitting structure, snap-fit, or threaded engagement, eliminating the need for an additional support 500. This creates a rigid, integrated structure between the two covers 100 in the axial direction, eliminating the gaps and tolerance accumulation that occur in separate assemblies. It ensures that the central axes of the upper and lower covers 100 are always aligned, and the rotation center of the rotating component 200 is not affected by installation errors. This simplifies the overall assembly process, reduces the number of parts, and lowers manufacturing and maintenance costs. Simultaneously, the direct connection between the two adjacent covers 100 strengthens the overall structural rigidity, improves vibration and thermal deformation resistance, and ensures a stable spatial relationship between the covers 100 during long-term operation. This guarantees a constant gap in the atomization zone, improves the consistency of water intake and atomization efficiency, and enhances the stability of system operation.

[0061] In one embodiment where the second cover 140 is assembled with the upper cover 400, the plurality of covers 100 include a first cover 130 and a second cover 140 arranged sequentially in the vertical direction. The top end of the first cover 130 is connected to the upper cover 400. A drive member 300 is disposed on the outer wall of the upper cover 400. The output shaft of the drive member 300 passes through the upper cover 400 and is fixedly connected to each rotating component 200. The second cover 140 and the upper cover 400 are fixedly connected by a bracket 500.

[0062] The bracket 500 is an independent rigid component, reliably connected at both ends to the upper cover 400 and the second cover 140 respectively, forming an axial positioning structure. This ensures that the second cover 140 is stably supported by the bracket 500 in the vertical direction, without relying on the structural strength of the upper cover 400 to bear its weight. This prevents the upper cover 400 from deforming under stress, thus avoiding misalignment of the coaxiality between the output shaft of the drive component 300 and the rotating component 200. Simultaneously, the bracket 500 separates the second cover 140 from the upper cover 400, allowing the upper cover 400 to bear only the installation load of the drive component 300, unaffected by thermal deformation or vibration of the lower cover 100. This ensures smooth rotation of the output shaft, improves the assembly accuracy and operational stability of the multi-stage atomization structure, extends the service life of the drive component 300 and the rotating component 200, and facilitates maintenance of each cover 100.

[0063] Specifically, the second cover 140 is provided with a first condensate delivery channel 101, which is connected to the water storage chamber 111. The upper cover 400 is provided with a second condensate delivery channel 401, and the bracket 500 is provided with a third condensate delivery channel 501. The two ends of the third condensate delivery channel 501 are connected to the second condensate delivery channel 401 and the first condensate delivery channel 101, respectively.

[0064] A first condensate delivery channel 101 is provided on the second cover 140, which is connected to the water storage chamber 111, for receiving condensate and guiding it into the atomization area. A second condensate delivery channel 401 is provided on the upper cover 400, located on the outer wall of the upper cover 400, for introducing water from the condensate collection area of ​​the heat exchanger. A third condensate delivery channel 501 is provided on the bracket 500, with its upper end connected to the second condensate delivery channel 401 of the upper cover 400 and its lower end connected to the first condensate delivery channel 101 of the second cover 140, forming a continuous water flow path. The bracket 500 serves as an intermediate medium for condensate delivery, connecting the water inlet channel on the outside of the upper cover 400 to the water storage chamber 111 of the lower cover 100, enabling precise delivery of condensate. The condensate flows entirely within the channel, preventing leakage or contact with the drive component 300, and reducing interference from water vapor to the motor and rotating mechanism. While fulfilling its structural connection function, the bracket 500 also integrates water supply function, realizing the integrated design of structure and flow channel, reducing the amount of independent pipelines and reducing assembly complexity.

[0065] This application also provides a gas water heater, such as Figure 5 As shown, it includes a body 600, an atomizing device 700, and a fan 800. The atomizing device 700 is disposed inside the body 600, and the fan 800 is disposed above the atomizing device 700. The air inlet of the fan 800 faces the atomizing device 700, and the air outlet of the fan 800 faces the outside of the body 600. The atomizing device 700 is the one described above.

[0066] In the gas water heater embodiment provided by this invention, the body 600 is the framework of the entire system, including main components such as the combustion chamber, heat exchanger, and flue, as well as auxiliary components such as control circuits and user interface. An atomizing device 700 is integrated inside the body to optimize the atomization and discharge process of condensate. The atomizing device 700 is preferably located between the combustion chamber and the flue, so that the atomized condensate can be discharged through the flue along with the flue gas without affecting the combustion process or heat exchange efficiency. Specifically, the water storage chamber 111 of the atomizing device is connected to the condensate collection system inside the body. When the condensate is cooled in the combustion chamber and heat exchanger and collects in the water storage chamber, the cover 100 is activated to atomize the condensate and discharge it with the flue gas.

[0067] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0068] Multiple enclosures 100 are arranged sequentially in a vertical direction. Each atomization structure is formed by a centrifugal disc 220 and a grid structure 120. The upper centrifugal disc 220 and the upper grid structure 120 are opposite each other to process the condensate dripping into the upper water storage chamber 111, forming the first stage of atomization. The lower centrifugal disc 220 and the upper grid structure 120 are opposite each other to process the condensate dripping into the lower water storage chamber 111, forming the second stage of atomization, and so on. Since the water storage chamber 111 of each enclosure 100 is independently inlet, there is no droplet backflow, and the atomization process is uninterrupted between each stage. Each stage of atomization only acts on the condensate of its own stage, achieving parallel multi-point atomization. This multi-stage independent atomization structure improves the atomization efficiency of condensate, has a compact structure, stable operation, and no risk of water accumulation, solving the problem of low atomization efficiency in existing gas water heaters.
