Abstract
Description
Technical Field
[0001] This utility model belongs to the field of household appliance technology, specifically relating to an atomizer with a cooling structure, a condensate drain device, and a condensing gas water heater. Background Technology
[0002] Condensing gas water heaters are high-efficiency and energy-saving water heating devices that produce acidic condensate during operation. Currently, atomizing this acidic condensate and discharging it with the flue gas is one of the trends in condensate treatment. Previous technology sends the condensate to a rotating disc, which is driven by a drive unit to rotate, throwing the water out and colliding it with any surface, thus atomizing the condensate and discharging it with the flue gas produced by combustion. However, the drive unit heats up during prolonged operation and may even malfunction, reducing its lifespan and affecting the normal operation of the condensing gas water heater. Therefore, to address these problems and technical needs, it is necessary to improve existing condensate treatment devices. Summary of the Invention
[0003] To address the aforementioned problems, the purpose of this invention is to provide a centrifugal atomizer with a cooling structure, which can atomize and discharge condensate while also cooling the motor, effectively solving the problem of motor overheating during prolonged operation in the prior art and extending the motor's service life.
[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] An atomizer with a cooling structure includes an atomizing chamber, an atomizing disc, and a motor; the atomizing disc is connected to the motor; the atomizing disc is located inside the atomizing chamber; the outer wall of the motor is provided with a cooling shell; the cooling shell has a cavity structure; the cooling shell is provided with a water inlet and a water outlet.
[0006] In this invention, condensate is transported to the atomizing disc, which is driven by a motor to rotate, throwing the water out to collide with the atomizing chamber, forming a water mist. This mist is then discharged from the gas water heater along with the flue gas generated by combustion in the main combustion chamber. The cooling shell is used to cool the motor. In practical applications, cooling water can be introduced into the cooling shell through the inlet, and then exited through the outlet to achieve water circulation cooling of the motor and prevent it from overheating.
[0007] Furthermore, the cooling shell is located on all or part of the outer wall of the motor. Preferably, the cooling shell is located on part of the outer wall of the motor, which achieves the effect of cooling the motor while facilitating the installation of the motor.
[0008] Preferably, a water flow channel is formed between the water outlet and the upper surface of the atomizing disc. In practical applications, the positions of the water inlet and outlet are not specifically limited. Condensed water can be introduced into the cooling shell through the water inlet. When the water outlet is located at the bottom of the cooling shell and opposite the atomizing disc, the introduced condensed water flows out through the water outlet and directly onto the atomizing disc. When the water outlet is not located at the bottom of the cooling shell and is not opposite the atomizing disc, the introduced condensed water flows out through the water outlet and flows onto the atomizing disc through the water flow channel.
[0009] Preferably, the cooling shell is provided with a plurality of baffles. More preferably, the baffles include a flow divider and a flow guide; the two sidewalls of the flow divider contact the sidewalls of the cooling shell, while the upper and lower bottom surfaces do not contact the upper and lower walls of the cooling shell; the flow guide is located between two adjacent flow dividers, with one sidewall contacting the sidewall of the cooling shell, and the upper and lower bottom surfaces contacting the upper and lower walls of the cooling shell, respectively. The baffles are used to ensure water circulation and increase the contact area between the incoming cooling water and the motor. In practical applications, the structure of the baffles is not limited, as long as water circulation can be achieved.
[0010] Furthermore, the cooling shell and the atomizing cavity can be either separate or integrated structures. The sidewall of the atomizing cavity can be flat, with the cooling shell located on or passing through the sidewall of the atomizing cavity and attached to it via a conventional snap-fit method; that is, the cooling shell and the atomizing cavity are separate structures. Alternatively, the sidewall of the atomizing cavity can protrude outwards or recess inwards, making the cooling shell and the atomizing cavity an integrated structure. More preferably, the sidewall of the atomizing cavity is recessed inwards, making the cooling shell and the atomizing cavity an integrated structure. This facilitates motor installation and prevents the motor from contacting the condensate mist, further extending the motor's service life.
[0011] Preferably, the atomizing chamber is provided with an air inlet and an air outlet; the atomizing disc is located between the air inlet and the air outlet. The air inlet is used to introduce airflow and carry away the condensed water mist from the air outlet.
[0012] Preferably, a grid is provided on the outer side of the atomizing disc and inside the atomizing chamber. The grid includes a fixing ring and columns arranged at intervals on the fixing ring. The condensed water thrown off the atomizing disc collides with the grid to form a condensed water mist. The grid is fixed using conventional technology and can be installed on the atomizing chamber using conventional connectors, as long as the grid can be fixed to the outer side of the atomizing disc.
[0013] Preferably, a water-air separator is provided below the atomizing disc. Further, the water-air separator has a ring-shaped structure; the water-air separator is partially or entirely located within the atomizing chamber. In practical applications, some condensate will flow back to the bottom of the atomizing disc and then rise again with the flue gas. This condensate flowing back and rising with the flue gas encounters and adheres to the lower surface of the atomizing disc, affecting its balance and thus consuming additional motor power. By setting up a water-air separator, the flowing condensate and flue gas can be separated, preventing the flowing condensate from being carried out again by the flue gas and affecting the stability of the atomizing disc's operation.
[0014] As a preferred example, the outer wall of the water-air separator is provided with a recovery element; the recovery element is sealed and connected to the inner wall of the atomizing chamber to form a water return temporary storage chamber; the water return temporary storage chamber is provided with a drain pipe. The recovery element is a plate-like or sheet-like structure, located between the outer wall of the water-air separator and the inner wall of the atomizing chamber, used to isolate the flue gas; when the recovery element is sealed and connected to the inner wall of the atomizing chamber, the returned condensate and flue gas can be completely separated, preventing the returned condensate from being carried out again by the flue gas, improving the stability of the atomizing disc and motor operation. The formed water return temporary storage chamber can store the returned condensate. In practical applications, one end of the drain pipe is connected to the water return temporary storage chamber, and the other end is connected to the condensate collection chamber, used to transport the returned condensate to the condensate collection chamber for re-atomization and discharge.
[0015] This utility model discloses a condensate drainage device, including a condensate collection chamber, a water delivery device, and the aforementioned atomizer with a cooling structure; the water delivery device includes a water delivery pipe; one end of the water delivery pipe is connected to a water inlet. The condensate collection chamber is used to collect condensate generated from preheated cold water, and the water delivery device is used to transport the condensate to the cooling shell, thereby maximizing the utilization of condensate.
[0016] This utility model discloses a condensing gas water heater, including the aforementioned condensate discharge device; the atomizer with a cooling structure of the condensate discharge device is located inside or outside the condensing gas water heater.
[0017] When the atomizer with a cooling structure is located inside the condensing gas water heater, the air inlet is connected to the condenser, a conventional component of the condensing gas water heater, and the air outlet is connected to the flue pipe, a conventional component of the condensing gas water heater. The water supply device sends the condensate in the condensate collection chamber to the cooling shell to cool the motor. The outflowing condensate flows through the water flow channel to the atomizing plate for atomization. The resulting condensate mist is then carried out of the atomizing chamber by the flue gas generated by combustion and discharged outdoors through the flue pipe.
[0018] When the atomizer with a cooling structure is located outside the condensing gas water heater, the atomizer with a cooling structure is connected in series with the air inlet and outlet of the atomizing chamber at any position on the flue pipe of the conventional component of the condensing gas water heater. The water supply device sends the condensate in the condensate collection chamber to the cooling shell to cool the motor. The outflowing condensate flows through the water flow channel to the atomizing plate for atomization. The formed condensate mist is then carried out of the atomizing chamber by the flue gas generated by combustion and discharged outdoors through the flue pipe.
[0019] Due to the application of the above technical solutions, the beneficial effects of this utility model compared with the prior art are as follows: This utility model can atomize and discharge condensate water. In particular, by setting a cooling shell and a water flow channel, the condensate water flows through the cooling shell before being transported to the atomizing plate, and is used to cool the motor, thereby maximizing the utilization of condensate water, solving the problem of motor overheating during long-term operation in the prior art, and extending the service life of the motor; This utility model ensures water circulation by setting a baffle inside the cooling shell, and increases the contact area between the incoming cooling water and the motor.

[0032] The outer wall of the motor is provided with a cooling shell 4. The cooling shell and the atomizing cavity are an integral structure. The side wall of the atomizing cavity is recessed into the atomizing cavity to form a certain space, which is located on part of the outer wall of the motor.
[0033] The motor shaft passes through the cooling shell and connects to the atomizing disc, which is located between the air inlet and the air outlet.
[0034] The cooling shell has a hollow structure with a water inlet 401 and a water outlet 402. The water inlet is located at the top of the cooling shell, and the water outlet is located at the bottom of the cooling shell, opposite to the atomizing plate.

[0035] The cooling shell is equipped with a plurality of baffles. The baffles include a flow divider 5 and a flow guide 6. The two side walls of the flow divider are in contact with the side walls of the cooling shell, while the upper and lower bottom surfaces are not in contact with the upper and lower walls of the cooling shell. The flow guide is located between two adjacent flow dividers, with one side wall of the flow guide in contact with the side wall of the cooling shell, and the upper and lower bottom surfaces in contact with the upper and lower walls of the cooling shell, respectively.

Example 2
[0038] Based on Embodiment 1, the difference in this embodiment is that the side wall of the atomizing cavity is flat, the cooling shell and the atomizing cavity are separate structures, the cooling shell passes through the side wall of the atomizing cavity and is installed on the atomizing cavity by conventional snap-fit method, and the rest is the same. Example 3
[0039] Based on Embodiment 1, the difference in this embodiment is that the baffle is omitted, while the rest is the same. Example 4
[0040] Based on Embodiment 1, the difference in this embodiment is that the grille is omitted, while the rest is the same. Example 5
[0041] A condensate drainage device includes a condensate collection chamber 12, a water delivery device, and an atomizer with a cooling structure as described in Embodiment 1. The water delivery device includes a conventional water delivery pipe 13 and a water pump 14.

[0043] The specific method for draining condensate is as follows:
[0044] (1) When the condensing gas water heater is working, it produces high-temperature flue gas and condensate, and the condensate is stored in the condensate collection chamber;
[0045] (2) The condensate is pumped to the cooling shell and then flows from the outlet to the atomizing plate. The motor drives the atomizing plate to rotate, which throws the water out and collides with the grid to form condensate mist. The high-temperature flue gas enters the atomizing chamber and carries the condensate mist out and discharges it through the exhaust pipe.
[0046] Furthermore, the returned condensate falls into the return water storage chamber and is then transported by the drain pipe to the condensate collection chamber, repeating step (2). Example 7
[0047] A condensing gas water heater includes the condensate discharge device of Embodiment 5; an atomizer with a cooling structure is located outside the condensing gas water heater, and the air inlet of the atomizing chamber is connected to the exhaust pipe of a conventional component. In practical applications, the other end of the atomizing chamber can also be connected to an exhaust pipe of a conventional component, depending on the need. Comparative Example 1
[0048] Based on Example 6, one end of the water supply pipe passes through the wall of the atomizing chamber and is located on the atomizing disc, while the other end is connected to the water pump. Everything else remains the same; that is, the condensate is directly delivered to the atomizing disc and does not flow through the cooling shell. The condensate discharge device is described in [reference needed]. Figure 7 .
