Technical Field
[0001] The utility model belongs to the technical field of household appliances, and particularly relates to an eccentric water removal structure and device. Background Art
[0002] At present, vaporizing water and discharging it along with flue gas is one of the trends in the removal of condensed water from gas water heaters. In order to solve the problems of inconvenient use and poor use effect caused by using an external water storage container or additionally arranging a condensed water drain pipe in the prior art, a high-speed gas source device is used to drive an atomizing head to atomize all or most of the condensed water into tiny droplets, which are discharged through the smoke exhaust pipe of the gas water heater, thus solving the problem of discharging acidic condensed water from a condensing gas water heater. In order not to change the appearance of the burner, the water removal structure is generally placed in the extension pipe of the smoke exhaust pipe. It is found in practical applications that water droplets appear at the smoke exhaust port, which has an adverse effect on the building facade after a period of time and even causes slight corrosion. Therefore, it is necessary to improve the water removal structure and adopt a new mechanical structure to relieve the dripping problem on the basis of not affecting the appearance and operation of the burner. Summary of the Invention
[0003] Aiming at the above problems, the purpose of the utility model is to provide an eccentric water removal structure and device, which realizes the water removal function and relieves the dripping problem existing in the prior art during the water removal process, and avoids the corrosion phenomenon on the building facade.
[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0005] An eccentric water removal structure includes a turntable, a turntable driving device, and a hollow cavity; the hollow cavity includes an air inlet and an air outlet; the turntable is connected with the turntable driving device; the turntable driving device is arranged inside or outside the hollow cavity; the turntable is located between the air inlet and the air outlet; among the axes of the turntable, the air inlet, and the air outlet, at least two axes are not on the same straight line.
[0006] In the utility model, the axis refers to a straight line that extends infinitely. Flue gas flows from the main combustion chamber into the hollow cavity through the air inlet, and then enters the smoke exhaust pipe through the air outlet. At the same time, the water vapor formed by the turntable throwing water in the hollow cavity is carried into the smoke exhaust pipe and discharged from the burner together; among the axes of the turntable, the air inlet, and the air outlet, at least two axes are not on the same straight line. Under this structure, the flow path of the flue gas through the air inlet and the flow path of the flue gas / water vapor mixture are different, weakening the ability of the relatively large-sized water vapor particles in the water vapor to rush out with the flue gas.
[0007] In the utility model, among the axes of the turntable, the air inlet, and the air outlet, at least two axes are not on the same straight line. The specific design can adopt the following several structures.
[0008] In the present utility model, the axis of the turntable and the axis of the air inlet are not on the same straight line; or the axis of the turntable and the axis of the air outlet are not on the same straight line; further, when the axis of the turntable and the axis of the air inlet are not on the same straight line, the axis of the turntable passes through the air inlet or does not pass through the air inlet; when the axis of the turntable and the axis of the air outlet are not on the same straight line, the axis of the turntable passes through the air outlet or does not pass through the air outlet. In this structure, there is partial overlap or no overlap between the turntable and the air inlet (or the air outlet).
[0009] As a preferred example, the axis of the air inlet coincides with the axis of the air outlet, and both are not on the same straight line as the axis of the turntable.
[0010] In the present utility model, the axis of the air inlet and the axis of the air outlet are not on the same straight line; further, the axis of the air inlet passes through the air outlet or does not pass through the air outlet. In this structure, there is partial overlap or no overlap between the air inlet and the air outlet.
[0011] As a preferred example, the axis of the air inlet coincides with the axis of the turntable; or the axis of the air outlet coincides with the axis of the turntable.
[0012] In the present utility model, the axis of the air inlet, the axis of the turntable, and the axis of the air outlet are not all on the same straight line; further, the axis of the air inlet passes through the air outlet or does not pass through the air outlet. In this structure, there is partial overlap or no overlap between the air inlet and the air outlet.
[0013] As common knowledge, the overlap in the present utility model refers to the projection of each component on the same plane, rather than the overlap in actual contact, which can be understood by those skilled in the art according to common knowledge.
[0014] In the present utility model, the turntable driving device is provided on the wall of the hollow cavity with an air outlet or an air inlet; or the turntable driving device is provided on the wall of the hollow cavity without an air outlet or an air inlet. Preferably, the turntable driving device is provided on the wall of the hollow cavity with an air outlet or an air inlet, and the turntable is horizontally arranged and horizontally rotated under the drive of the turntable driving device, which can provide better water throwing ability than vertical rotation.
[0015] As a preferred example, the turntable driving device is provided outside the wall of the hollow cavity with an air outlet or an air inlet, and this outside is opposite to the inside of the hollow cavity, which means that the turntable driving device is not inside the hollow cavity, reducing corrosion by water (smoke) and having a protective effect on the turntable driving device.
[0016] In the present utility model, a grille is provided inside the hollow cavity on the outside of the turntable; a water inlet pipe is provided above the turntable, and the water inlet pipe passes through the wall of the hollow cavity. As common knowledge, the water inlet pipe pumps condensed water onto the turntable.
[0017] The present utility model also discloses a device including the above eccentric water removal structure; the device is a device that needs water removal, and it may further include other conventional structures, such as a water storage tank, a water delivery device, etc. The water in the water storage tank can be sent to the above eccentric water removal structure through the water delivery device and discharged from the device. As an example, the device can be a condensing gas water heater.
[0018] In the present utility model, preferably, the axis of the air inlet coincides with the axis of the turntable, and neither of them is on the same straight line as the axis of the air outlet; this structure facilitates the flue gas in the eccentric water removal device to carry out the water vapor, improves the water removal efficiency, and the water vapor particles will flow back when they encounter the wall (such as the upper wall of the hollow cavity) during the outflow process.
[0019] Due to the application of the above technical solution, the beneficial effects of the present utility model compared with the prior art are as follows:
[0020] Currently, in the technical solution of atomized water removal, the water removal structure is located in the center of the extension pipe of the smoke exhaust pipe, which is a concentric structure. The flow paths of the flue gas and the flue gas / water vapor mixture are basically the same. The probability that the relatively large-sized water vapor particles in the water vapor rush out with the flue gas is relatively large. The relatively large-sized water vapor particles in the water vapor are relatively easy to condense. Some water vapor particles will flow back along the inner wall of the smoke exhaust pipe, but some water vapor particles will condense along the outer wall of the smoke exhaust pipe, resulting in water dripping at the smoke exhaust port or flowing down along the outer wall of the smoke exhaust pipe to the building facade; the present utility model can utilize the rotation of the turntable to shoot out water and collide with any facade to form water vapor, and then discharge it with the flue gas in the device to achieve the water removal function. In particular, the water removal structure of the present utility model is designed in an eccentric manner. Compared with the concentric design in the prior art, the innovative structure in which at least two of the axes of the turntable, the air inlet, and the air outlet are not on the same straight line weakens the ability of the relatively large-sized water vapor particles in the water vapor to rush out with the flue gas, weakens the water dripping phenomenon, and also avoids causing corrosion to the building.

[0031] Wherein: turntable 1, turntable driving device 2, hollow cavity 3, grille 4, condenser 5, smoke exhaust pipe 6, water storage tank 7, water conveying device 8, air outlet 301, air inlet 302, fixing ring 401, triangular prism 402. Specific embodiments
[0032] In the present utility model, a grille is provided on the outer side of the turntable and inside the hollow cavity; a water inlet pipe is provided above the turntable, and the water inlet pipe passes through the wall of the hollow cavity. As common knowledge, the water inlet pipe pumps the condensed water onto the turntable; preferably, the hollow cavity is a split structure, which is convenient for the installation of the turntable and the turntable driving device. The water in the water storage tank of the gas water heater is conveyed to the turntable by a conventional water conveying device (such as a water pump), and the turntable is driven by the turntable driving device to rotate, and the water is ejected to collide with the wall (preferably the grille) to form water vapor, which is discharged with the flue gas. Compared with the concentric water removal device in the prior art, in the present utility model, among the axes of the turntable, the air inlet, and the air outlet, the structure in which at least two axes are not on the same straight line can weaken the ability of the water vapor particles to rush out with the flue gas. In addition, there is a situation where the water vapor particles will flow back when they encounter the wall during the outflow process, and they can be atomized again, alleviating the dripping problem existing in the water removal process of the prior art and avoiding corrosion of the building surface.
[0033] The grille includes a fixing ring and columns arranged at intervals on the fixing ring, and the columns are prisms or cylinders. The turntable rotates and throws out water, which collides with the grille to form water vapor.
[0034] The eccentric water removal structure of the present utility model can be applied to a device that needs water removal, such as a condensing gas water heater, and the eccentric water removal structure can be connected to the condensing gas water heater through the air inlet and air outlet of the hollow cavity.
[0035] The eccentric water removal structure can be integrated into a condensing gas water heater as a component thereof. For example, the air inlet of the eccentric water removal structure is communicated with the condenser, a conventional component of the condensing gas water heater, and the air outlet is communicated with the smoke exhaust pipe, a conventional component of the condensing gas water heater. The water conveying device is connected to the water inlet pipe to send the condensed water to the turntable for atomization. The formed water vapor is then carried out of the hollow cavity by the flue gas generated by combustion and discharged outdoors through the smoke exhaust pipe. The eccentric water removal structure can also be used as a separate module and arranged outside the condensing gas water heater to cooperate with the condensing gas water heater. For example, the eccentric water removal structure is connected in series at any position of the smoke exhaust pipe, a conventional component of the condensing gas water heater, through the air inlet and air outlet of the hollow cavity. The water conveying device is connected to the water inlet pipe to send the condensed water to the turntable for atomization. The formed water vapor is then carried out of the atomization cavity by the flue gas generated by combustion and discharged outdoors. As another example, the air outlet of the hollow cavity of the eccentric water removal structure is open for fog discharge or is connected to a single pipe (different from the smoke exhaust pipe) for fog discharge. The water conveying device is connected to the water inlet pipe to send the condensed water to the turntable for atomization. The formed water vapor is then carried out of the hollow cavity by the flue gas generated by combustion or discharged outdoors by itself.
[0036] In the present utility model, the shape of the hollow cavity is not specifically limited as long as the technical effects of the present utility model can be achieved. In actual applications, a fan can also be provided above or below the turntable, which is designed by those skilled in the art according to actual needs.
[0037] The present utility model will be further described below in conjunction with the drawings and embodiments. The specific components involved are existing products. Conventional mounting holes are provided on the specific components, and the connection and usage methods between the specific components are conventional technologies.
[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present utility model. The terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. For example, the terms "inverted", "length", "width", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate the orientation or position based on the orientation or position shown in the drawings, which are only for convenience of description and should not be construed as a limitation to the technical solution of the present application.

[0058] Application Example
[0059] The prior art discloses a condensate water treatment device for a gas water heater, which uses an air pump to drive an atomizing head to atomize the condensate water and discharges it through an exhaust pipe channel. Replace the atomizing head with the eccentric water removal structure of the present utility model, omit the structures related to atomization such as the air pump, inject the condensate water onto the surface of the turntable by a water pump through a water inlet pipe, the air inlet of the hollow cavity faces the condensate pipe direction, and the air outlet is communicated with the smoke exhaust pipe; other structures are all conventional structures of a condensing gas water heater.
[0060] Dripping occurs in the actual use of the prior art, and a high-power motor is required for the high-pressure atomization method. The condensate water discharge device designed by the applicant before can use a motor with a relatively small power, but a 27W motor is also required to drive the turntable (see CN2024110520627). Once a small-power motor is used, a small amount of dripping will also occur. And for some gas water heaters with a small reserved power, at this time, the cavity of the water removal structure still needs to be improved.
[0061] The specific components involved in the eccentric water removal structure of the present utility model are existing products, and conventional installation holes are provided on the specific components. The connection and usage methods between the specific components are conventional technologies. A 13W motor is used as the driving device for the turntable, and a 6W water pump is used to pump water. The total power is less than 20W, and the reserved power supplies of current gas water heaters can all meet the requirements. Referring to the experimental method of CN2024110520627, for the smoke exhaust pipe (placed horizontally), there is almost no dripping at the smoke exhaust port connected to the eccentric water removal structure of Example 1, and there is a water film on the outer wall, while there is some dripping at the smoke exhaust port connected to the concentric water removal structure of the comparative example.
[0062] In the present utility model, the condensate water is transported to the turntable, and the turntable driving device drives the turntable to rotate, so that the water on the turntable is ejected, collides with the inner wall (preferably the grille) of the hollow cavity to form water vapor, and after converging with the flue gas coming from the air inlet, it is discharged into the smoke exhaust pipe through the air outlet and further discharged to the outside, completing the water removal. Since at least two of the axes of the turntable, the air inlet, and the air outlet are not on the same straight line, the ability of water vapor particles to rush out with the flue gas is weakened. In addition, there is a situation where water vapor particles will flow back when they encounter the wall during the outflow process, and they can be atomized again, alleviating the dripping problem existing in the water removal process of the prior art and avoiding corrosion of the building surface.
[0063] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
