Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, specifically relating to a waterproof atomizer, a condenser with an atomizing structure, and a condensing gasifier. Background Technology

[0002] Gas water heaters are widely used due to their energy-saving and environmentally friendly characteristics. They preheat cold water by absorbing the residual heat of the high-temperature flue gas produced by combustion, thus improving the thermal efficiency of the gas water heater. However, during the preheating process, water vapor in the high-temperature flue gas condenses into a large amount of liquid water in the condenser. Because the high-temperature flue gas produced by natural gas combustion contains a large amount of acidic substances (carbon oxides, sulfur oxides, nitrogen oxides, etc.), which dissolve in the water, the water becomes acidic and cannot be directly discharged outdoors. The discharge of this water remains a problem to be solved.

[0003] Currently, most gas water heaters on the market require a pre-installed drain outlet and drain pipe, which must be connected to a floor drain during installation. Alternatively, a temporary water storage container may be installed at the drain outlet, requiring frequent emptying by the user. Other solutions, such as connecting to other special drainage channels, are unpopular due to increased installation costs and complexity. Existing technologies utilize a drive device to rotate a disc, projecting water that collides with a grille to reduce energy consumption. However, because the drive device is exposed to the water mist and in direct contact with it, prolonged exposure to a humid environment leads to corrosion and a reduced lifespan. Therefore, to address these issues and technical requirements, it is necessary to improve existing atomizing devices to mitigate corrosion. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a waterproof atomizer, a condenser with an atomizing structure, and a condensing burner. By setting a protective shell and cooperating with a shaft seal, water mist is isolated from the drive equipment, effectively preventing water corrosion of the drive equipment.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A waterproof atomizer includes a driving device, an atomizing disc, and a grille; the driving device is provided with a protective shell on its outer side; the driving end of the driving device passes through the protective shell and is connected to the atomizing disc; a shaft seal is provided on the driving end; the grille is located on the outer side of the atomizing disc.

[0007] As is common knowledge, a driving device includes a body and a driving end, where the driving end refers to the power output end of the driving device. In this invention, water to be atomized is delivered to an atomizing disc, and the driving device drives the atomizing disc to rotate, ejecting water that collides with the grille to form a water mist. A protective shell is installed on the outside of the driving device to reduce corrosion caused by prolonged exposure to humid environments. Furthermore, this invention employs a shaft seal structure to further isolate the water mist, preventing it from penetrating the body from the driving end of the driving device, thus avoiding corrosion and extending its service life.

[0008] Preferably, the inner wall of the protective shell is not in complete contact with the outer wall of the driving device, which facilitates heat dissipation of the driving device. More preferably, the inner wall of the protective shell is provided with an isolation element, so that the inner wall of the protective shell is not in complete contact with the outer wall of the driving device. In practical applications, the isolation element can be an isolation column, an isolation ring, or other structure, selected as needed, as long as it ensures that the inner wall of the protective shell is not in complete contact with the outer wall of the driving device, thus providing heat dissipation space for the driving device without affecting the understanding of the technical effects of this invention by those skilled in the art.

[0009] Furthermore, the shaft seal is fitted onto the drive end; the shaft seal may be partially or entirely located inside the protective housing, or the shaft seal may be located outside the protective housing; the shaft seal has one or more sealing lips. The shaft seal is used to further isolate water mist and reduce the possibility of water mist flowing out from the gap between the drive end of the drive device and the protective housing. Preferably, the shaft seal has multiple sealing lips to improve the sealing effect. As is common sense, the shaft seal is in close contact with the protective housing.

[0010] Preferably, the waterproof atomizer further includes an atomizing housing; the atomizing housing is provided with an air inlet and a mist outlet; the protective shell is partially or entirely located on the atomizing housing.

[0011] In this invention, the shape of the atomizing shell is not specifically limited, as long as it can achieve the technical effect of this invention.

[0012] Furthermore, the waterproof atomizer also includes a water delivery mechanism for delivering water to be atomized to the atomizing disc.

[0013] A condenser with an atomizing structure includes the aforementioned waterproof atomizer. As is common knowledge, the condenser with the atomizing structure also includes conventional components of a conventional condenser, such as heat exchange tubes (condenser tubes), which utilize the flue gas generated by combustion to preheat cold water.

[0014] Furthermore, the condenser with the atomizing structure also includes a condenser housing; the condenser housing is provided with an air outlet, the protective shell is partially or entirely located inside the condenser housing, and the atomizing disc and grille are located inside the condenser housing; or the waterproof atomizer includes an atomizing housing, the condenser housing is provided with an air outlet, and the air outlet is connected to the air inlet of the atomizing housing; or the waterproof atomizer includes an atomizing housing, and the top part or entirely of the condenser housing is the atomizing housing.

[0015] In this invention, when the condenser shell is provided with an air outlet, the protective shell is partially or entirely located inside the condenser shell, and the atomizing disc and grille are located inside the condenser shell, in practical applications, the air outlet of the condenser shell is connected to the exhaust pipe of the conventional component of the burner, and the flue gas generated by combustion is discharged to the outside through the condenser shell and the exhaust pipe in sequence; or the waterproof atomizer includes an atomizing shell, the condenser shell is provided with an air outlet, and the air outlet is connected to the air inlet of the atomizing shell; or the waterproof atomizer includes an atomizing shell, and the top part or entirely of the condenser shell is the atomizing shell, in practical applications, the mist outlet of the atomizing shell is connected to the exhaust pipe of the conventional component of the burner, and the flue gas generated by combustion is discharged to the outside through the condenser shell, the atomizing shell, and the exhaust pipe in sequence.

[0016] Furthermore, the condenser with the atomizing structure also includes a water collection chamber; the waterproof atomizer also includes a water delivery mechanism; the water delivery mechanism is located between the water collection chamber and the atomizing plate. The water collection chamber is used to collect condensate generated from preheated cold water; the water delivery mechanism is used to deliver the condensate to the atomizing plate.

[0017] Furthermore, the water delivery mechanism includes a water pipe; a water channel is provided between the outlet of the water pipe and the atomizing plate. The water delivery mechanism also includes a water transport power device, such as a conventional water pump, for providing power for transporting condensate. The condensate transported by the water delivery mechanism is delivered to the atomizing plate through the water channel.

[0018] Preferably, the water inlet of the water channel faces downwards. In existing condensing gas water heaters, the condenser shell is generally connected to the flue pipe to form a flue gas flow path. The flue gas generated by combustion flows sequentially through the condenser shell and the flue pipe before being discharged outdoors. In this invention, the atomizing disc can be located above or below the water collection chamber, preferably above. This structure allows the waterproof atomizer to be directly placed in the conventional flue gas flow path, fully utilizing the flue gas to drive the water mist out. Considering cost, a flexible water pipe is preferred, as it offers greater installation flexibility and lower cost compared to a rigid pipe. However, if the atomizing disc is placed above the water collection chamber, the condensate needs to be transported from bottom to top. Setting the water inlet of the water channel downwards avoids bending of the flexible water pipe, ensuring normal condensate transport. If the atomizing disc is placed below the water collection chamber, the condensate is transported from top to bottom, altering the conventional flue gas flow path. This requires additional pipes to discharge the flue gas or to connect to the conventional flue gas flow path, not only failing to fully utilize the flue gas but also occupying space.

[0019] A condensing gasifier includes the aforementioned condenser with an atomizing structure. In this invention, the gasifier is a gas water heater.

[0020] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: In view of the problem that the existing condensate water (containing impurities) discharge scheme of the condensate water of the gas water heater is complicated and inefficient, the technical solution of water splashing and collision with the vertical surface of this utility model can effectively atomize the condensate water solution into water mist, which is discharged from the gas water heater with the flue gas, solving the problem of the existing technology of using an additional water storage container to discharge water, and the drainage effect is good. In particular, previous technical solutions involved the drive unit coming into contact with water mist, which, when exposed to a humid environment for extended periods, led to corrosion, reduced lifespan, and increased replacement frequency. This invention, by installing a protective shell on the outside of the drive unit, in conjunction with a shaft seal, isolates the drive unit from the water mist, effectively preventing water corrosion and extending its lifespan compared to previous solutions. Furthermore, by installing an insulating component on the inner wall of the protective shell, the inner wall of the shell does not completely contact the outer wall of the drive unit, improving heat dissipation. Moreover, to reduce production costs, this invention preferably uses a soft water pipe for water delivery, and to avoid affecting normal water supply, the water inlet of the water channel is designed to face downwards, preventing bending of the soft water pipe.

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific components involved are existing products, and the specific components are provided with conventional mounting holes. The connection and usage methods between the specific components are conventional technologies.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as “inverted,” “length,” “width,” “upper,” “lower,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer” indicate orientations or positions based on the orientations or positions shown in the accompanying drawings and are merely for the convenience of describing the following embodiments, and should not be construed as limiting the invention.

[0037] As is common knowledge, a condensing gas water heater includes a combustion chamber, a condenser, a water collection chamber, and a flue pipe. The condenser has a shell and internal heat exchange tubes (condenser tubes). The combustion chamber, condenser shell, and flue pipe are connected to form a flue gas flow path, allowing the flue gas generated in the combustion chamber to flow through the condenser and be discharged from the flue pipe. In the condenser shell, the surface from which the flue gas flows out of the condenser shell is considered the top of the condenser shell, and an outlet is provided on it. This outlet can be part of the top or the entire top (in this structure, the top of the condenser shell is an open structure, i.e., fully open). The atomizing mechanism (atomizing disc, grille) of this utility model is located on the flue gas discharge path, allowing the atomized condensate solution to be discharged from the gas water heater along with the flue gas. Example 1

[0038] like Figures 1 to 3 As shown:

[0039] A waterproof atomizer includes a drive device 1, an atomizing disc 2, a grille 3, and an atomizing housing 4. The drive device is a conventional brushless motor with a protective housing 5 on the outside.

The grille is located on the outside of the atomizing disc and includes a fixing ring 301 and atomizing columns 302 arranged at intervals on the fixing ring. It is installed on the inner wall of the atomizing housing by conventional connectors, such as bolts.

[0040] A shaft seal 6 is fitted onto the shaft of the brushless motor. The shaft seal is entirely located inside the protective housing and is in close contact with the housing. In this embodiment, the shaft seal has three sealing lips 601, see [reference]. Figure 3 .

[0041] The atomizing housing has an air inlet 401 and a mist outlet 402. In this embodiment, the entire bottom of the atomizing housing is an air inlet, meaning the bottom of the atomizing housing is an open structure, and the top part of the atomizing housing is the mist outlet, meaning the top of the atomizing housing is a semi-closed structure. See [link to documentation]. Figure 1 , Figure 2 The protective shell is entirely located on the atomizing shell. In this invention, the shape of the atomizing shell is not specifically limited, as long as it achieves the technical effect of this invention.

[0042] In this embodiment, the inner wall of the protective shell is provided with an isolation column 7, so that the inner side wall of the protective shell is not in complete contact with the outer side wall of the drive device, thereby providing heat dissipation space for the drive device. Example 2

[0043] Based on Embodiment 1, the difference in this embodiment is that the bottom part of the atomizing housing is the air inlet, that is, the bottom of the atomizing housing is a semi-enclosed structure. See [link to embodiment 1]. Figure 4 The rest are the same. Example 3

[0051] In this embodiment, the atomizing disc is located above the water collection chamber, and a water channel 14 is provided between the outlet of the silicone hose and the atomizing disc, located on the atomizing housing. (See also...) Figure 13 The water inlet of the water channel faces downwards, see [reference]. Figure 12 This can prevent the soft water pipes from bending and ensure the normal delivery of condensate.

[0052] The specific usage method is as follows:

[0054] (2) The water pump delivers the condensate to the atomizing plate. The brushless motor drives the atomizing plate to rotate, spraying water onto the grid to form water mist.
