Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to an energy-saving split-type household water-cooled tower fan. Background Technology

[0002] Most existing household water-cooled tower fans adopt an integrated fixed structure, with the evaporative cooling pad, water distributor, and drip tray all integrated inside the casing. After prolonged use, scale and dust accumulate on the surface of the cooling pad, causing airflow blockage and a significant increase in wind resistance. To maintain the nominal airflow, the fan motor is forced to operate at increased power, significantly reducing overall energy efficiency and increasing power consumption, failing to meet the requirements of energy-efficient household appliances. While some products allow the cooling pad to be removed for cleaning, their installation structure is a simple drawer-type gap fit. After reinsertion, steps and gaps exist between the cooling pad assembly and the inner wall of the air duct, causing turbulence and air leakage, negating the heat exchange performance restored by cleaning, resulting in limited energy savings. Furthermore, the condensate and impurities collected at the bottom of the cooling pad can easily breed bacteria, further reducing heat exchange efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an energy-saving split-type household water-cooled tower fan, which has the advantages of forming a double airtight seal by combining a sealing convex gasket, avoiding cold air bypass, maximizing the effective cooling air volume output, indirectly saving energy, forming a labyrinth-type double seal, further blocking the leakage of hot and humid air to the outside of the casing, increasing the static pressure on the air outlet side of the water-cooled fan, and reducing energy loss.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving split-type household water-cooled tower fan, comprising a tower fan shell and an impeller assembly disposed at its center, wherein the outer wall of the impeller assembly is partially covered by a water-cooled baffle. The water-cooled baffle is assembled with the tower fan housing via mounting components; The installation assembly includes a hydrophobic ring plate, a curved clamp, a sealing assembly, and a flow guide. The hydrophobic ring plate is fixed below the water-cooled partition fan. Curved clamps are connected to both the inner and outer sides of the hydrophobic ring plate. A sealing assembly is provided below the hydrophobic ring plate, and a flow guide is provided inside the hydrophobic ring plate. The tower fan shell has an inner cavity for water-cooled fan insertion and installation, and the bottom of the inner cavity has an installation groove for movably inserting with the hydrophobic ring plate. The water-cooled baffle is inserted into the inner cavity from the top of the tower fan shell, and the bottom end is connected to the wall of the mounting groove through a bent clamp. The bottom end of the hydrophobic ring plate is sealed to the inner wall of the mounting groove through a sealing component.

[0005] Furthermore, a water storage cavity is provided at the upper end of the tower fan shell, and a sealing plate is installed on one side of the water storage cavity by means of a spring. A water inlet hole for communicating with the upper end of the water-cooled fan is provided on one side of the water storage cavity, and the sealing plate is used to block the water inlet hole.

[0006] Furthermore, the upper end of the water-cooled partition is provided with an annular plate, one side of the annular plate is provided with a water inlet groove communicating with the water inlet hole, and the lower part of the annular plate is provided with a permeation hole communicating with the fan layer of the water-cooled partition.

[0007] Furthermore, the water-cooled fan is provided with support columns at both ends, and a water storage tank is provided below the fan shell. The support columns are provided with pipes for connecting the water storage tank and the water storage cavity, and the pipes are used to transport water from the water storage tank to the water storage cavity through a water pump.

[0008] Furthermore, the bending clamp includes an inner bending clamp and an outer bending clamp. An extension plate is provided at the upper end of the mounting groove to engage and clamp the inner bending clamp and the outer bending clamp. Friction strips are provided on the clamping end faces of the inner bending clamp and the outer bending clamp.

[0009] Furthermore, the sealing assembly includes an annular pressure plate, an external air ring, an inflation groove, and a pressing rod. The annular pressure plate is located below the hydrophobic ring plate. An external air ring is provided on the outer wall of the annular pressure plate. An inflation groove communicating with the external air ring is opened on the inner wall of the annular pressure plate. A pressing rod is provided in a sealed fit on the inner wall of the inflation groove.

[0010] Furthermore, the inner wall of the mounting groove is provided with a corresponding sealing convex gasket, and the external air ring is inflated and engages with the sealing convex gasket.

[0011] Furthermore, a guide hole is provided at one end of the hydrophobic ring plate, and a pipe is provided below the guide hole to connect with the sewage storage tank.

[0012] Furthermore, the flow guide includes a bracket, a scraper, a movable plate, a tension spring, and a limiting plate. The bracket is fixed to the movable plate by a bearing. One end of the movable plate is connected to the tension spring. One end of the bracket is connected to the scraper, which is in movable contact with the inner wall of the hydrophobic ring plate.

[0013] Furthermore, a limiting track groove is provided on the limiting plate, and one end of the bracket passes through the limiting track groove and is connected to the impeller assembly for transmission.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention designs the water-cooled baffle as an independent and detachable component. By quickly plugging and positioning the mounting components with the tower fan housing, users can remove the water-cooled baffle by hand for deep cleaning or replacement. This effectively eliminates the problems of air duct blockage and heat exchange efficiency reduction caused by the accumulation of dirt on the wet curtain, allowing the impeller assembly to operate in a low wind resistance and low load state for a long time, thereby significantly reducing the power consumption of the whole machine and meeting the needs of household appliances for energy-saving components.

[0015] 2. This invention utilizes the elastic clamping of the bent clamping clip in conjunction with the friction strip, and the structural design of the external gas ring being passively inflated by the pressing rod in the sealing assembly. After the water-cooled fan is inserted into the mounting slot, it automatically completes mechanical locking and gas sealing. The seal is automatically released during disassembly, ensuring reliable sealing between the split-type components and the air duct, preventing cold air bypass loss, and maintaining ease of disassembly and assembly. The external gas ring and the sealing convex gasket in the mounting slot form a double labyrinth seal, further blocking the leakage of humid and hot air, increasing the effective air output ratio, and indirectly reducing the fan's energy consumption.

[0016] 3. This invention utilizes the spring sealing plate at the water storage cavity of the tower fan shell to cooperate with the annular plate at the upper end of the water-cooled baffle. When the water-cooled baffle is inserted, the water inlet is automatically opened, and when it is pulled out, the sealing plate automatically resets and blocks the water inlet hole. This enables the split-type components to be plugged in and turned off immediately, eliminating water leakage and ineffective wetting, and avoiding the waste of water resources and circulating water pump energy.

[0017] 4. The present invention integrates a flow guide within the hydrophobic ring plate. The rotating shaft of the impeller assembly drives the bracket to reciprocate along the limiting track groove via the gearbox and drive ring. This causes the scraper to alternately move down to scrape water and then tilt up to reset. In a zero-additional-power manner, wastewater and impurities deposited at the bottom of the hydrophobic ring plate are forcibly transported and discharged through the flow guide holes. This prevents sludge accumulation from causing poor drainage and wind resistance rebound, ensuring that the water-cooled fan maintains optimal water flow and minimum wind resistance throughout its entire life cycle, achieving continuous energy-saving self-maintenance based on wind power recovery.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Reference Figure 1 - Figure 8 The present invention provides an energy-saving split-type household water-cooled tower fan, including a tower fan shell 1 and an impeller assembly 11 disposed at its center. The outer wall of the impeller assembly 11 is partially covered by a water-cooled baffle 2. The water-cooled baffle 2 is an independent and replaceable part of the energy-saving household appliance and can be completely removed from the tower fan shell 1 for easy cleaning or replacement, so as to restore the tower fan to its initial low wind resistance state and maintain energy-saving operation.

[0022] The water-cooled baffle 2 is assembled with the tower fan housing 1 via the mounting assembly 3; The mounting assembly 3 includes a drainage ring plate 31, a curved clamp 32, a sealing assembly 33, and a flow guide 34. The drainage ring plate 31 is fixed below the water-cooled fan 2. Curved clamps 32 are connected to both the inner and outer sides of the drainage ring plate 31, and a sealing assembly 33 is provided below the drainage ring plate 31. A flow guide 34 is provided inside the drainage ring plate 31. The mounting assembly 3 enables the rapid positioning, clamping and sealing of the water-cooled fan 2 and drainage of accumulated water, ensuring that the component is smoothly connected to the internal air duct of the tower fan after installation, eliminating additional air resistance.

[0023] The tower fan housing 1 has an inner cavity for the water-cooled baffle 2 to be inserted and installed, and the bottom of the inner cavity has an installation groove 12 for movably inserting with the hydrophobic ring plate 31; the water-cooled baffle 2 is an independent and replaceable energy-saving household appliance component, which can be completely removed for deep cleaning or replacement, eliminating the increased wind resistance and reduced heat exchange efficiency caused by dirt accumulation, so that the tower fan always operates in the low load range, significantly reducing the energy consumption of the whole machine.

[0024] The water-cooled baffle 2 is inserted into the inner cavity of the tower fan housing 1 from the top, and the bottom end is connected to the wall of the mounting groove 12 through the bent clamp 32. The bottom end of the hydrophobic ring plate 31 is sealed to the inner wall of the mounting groove 12 through the sealing component 33. An airtight connection is formed between the lower part of the water-cooled baffle 2 and the mounting groove 12 to prevent bypass airflow that has not been cooled by evaporation from leaking into the air outlet, thereby increasing the effective air outlet ratio and reducing the ineffective power consumption of the fan.

[0025] With a design that allows for easy disassembly and assembly without bolts, users can replace the two core components of the water-cooled baffle fan themselves without scrapping the entire unit. This extends the lifespan of the electrical components and maintains energy efficiency through component replacement.

[0026] The upper part of the tower fan housing 1 has a water storage chamber. A sealing plate 13 is installed on one side of the water storage chamber via a spring. A water inlet hole for communication with the upper part of the water-cooled fan 2 is opened on one side of the water storage chamber. The sealing plate 13 is used to block the water inlet hole. When the water-cooled fan 2 is inserted, the annular plate 21 pushes open the sealing plate 13, automatically opening the water inlet. When the water-cooled fan 2 is pulled out, the sealing plate 13 is reset and blocked by the spring, realizing the instant water supply and instant water cut-off of the split components, eliminating water leakage and ineffective wetting, and saving the energy consumption of the circulating water pump.

[0027] The upper end of the water-cooled partition fan 2 is provided with an annular plate 21. A water inlet groove communicating with the water inlet hole is provided on one side of the annular plate 21, and a permeation hole communicating with the fan layer of the water-cooled partition fan 2 is provided below the annular plate 21. Water from the water storage chamber evenly wets the entire fan layer of the water-cooled partition fan 2 through the water inlet hole, water inlet groove and permeation hole, forming a large area of ​​uniform water film, increasing the air-water heat exchange area, improving evaporation efficiency, thereby obtaining a lower outlet air temperature at the same fan speed, reducing the investment in compressor or additional cold source, and achieving the purpose of energy saving.

[0028] The water-cooled partition fan 2 has support columns 22 at both ends, and a water storage tank is located below the tower fan shell 1. The support columns 22 have pipes for connecting the water storage tank and the water storage cavity. The pipes transport water from the water storage tank to the water storage cavity through a water pump. The support columns 22 serve as both structural support and water channels, realizing the integrated water flow between the split water-cooled partition fan 2 and the host, avoiding exposed hoses, and improving the integrity and reliability of the components.

[0029] The support column 22 contains a circulating water channel, and the sewage is directly discharged into the independent storage tank through the guide hole 311. The clean water and sewage are separated, which avoids the accelerated scaling caused by the increase of circulating water concentration and maintains high evaporation efficiency and low wind resistance.

[0030] The bending clamp 32 includes an inner bending clamp 321 and an outer bending clamp 322. An extension plate is provided at the upper end of the mounting groove 12 to engage and clamp the inner bending clamp 321 and the outer bending clamp 322. Friction strips are provided on the clamping end faces of both the inner bending clamp 321 and the outer bending clamp 322. Through the elastic clamping and the cooperation of the friction strips, the water-cooled partition fan 2 automatically grips the extension plate of the mounting groove 12 after insertion, achieving reliable vertical fixation of the components. It can withstand wind pressure and vibration without loosening, and requires no additional bolts or tools, facilitating manual disassembly and maintenance by the user.

[0031] The sealing assembly 33 includes an annular pressure plate 331, an external air ring 332, an inflation groove 333, and a pressing rod 334. The annular pressure plate 331 is located below the hydrophobic ring plate 31. An external air ring 332 is provided on the outer wall of the annular pressure plate 331. An inflation groove 333, which communicates with the external air ring 332, is opened on the inner wall of the annular pressure plate 331. The pressing rod 334 is sealed and fitted to the inner wall of the inflation groove 333. When the water-cooled fan 2 is inserted into place, the bottom of the mounting groove 12 squeezes the pressing rod 334, pushing the air in the inflation groove 333 into the external air ring 332, causing the air ring to expand radially and passively completing the inflation and sealing. When disassembling, the pressure is released, and the air ring automatically contracts for easy removal. This adaptive air seal design ensures that the split-type components fit tightly with the air duct during operation, while there is no interference resistance during disassembly, balancing sealing performance and ease of disassembly and assembly.

[0032] The mounting component 3 integrates mechanical clamping, pneumatic sealing, and mechanical top-opening water-stopping structure, enabling the water-cooled partition fan 2 to be plugged in and unplugged and stopped immediately, with no water or air leakage. The external air ring 332 passively inflates and expands to seal, forming a double airtight seal with the sealing convex gasket, preventing cold air bypass and maximizing the effective cooling air volume output, thus indirectly saving energy.

[0033] The inner wall of the mounting slot 12 is provided with a corresponding sealing convex gasket. After the external air ring 332 is inflated, it engages with the sealing convex gasket. The inflated external air ring 332 is embedded in the annular groove formed by the sealing convex gasket, forming a labyrinth-type double seal, which further blocks the leakage of hot and humid air to the outside of the casing, increases the static pressure on the air outlet side of the water-cooled fan 2, and reduces energy loss.

[0034] A guide hole 311 is provided at one end of the hydrophobic ring plate 31, and a pipe extending below the guide hole 311 connects to the sewage storage tank. Excess spray water and dust impurities on the surface of the water-cooled baffle 2 flow along the fan layer into the hydrophobic ring plate 31, and are discharged into the sewage storage tank through the guide hole 311 and the pipe, preventing water accumulation in the air duct from forming additional moisture resistance and bacterial growth, and maintaining long-term low wind resistance and energy-saving operation.

[0035] The flow guide 34 includes a bracket 341, a scraper 342, a movable plate 343, a tension spring 344, and a limiting plate 345. The bracket 341 is fixed to the movable plate 343 by bearings. One end of the movable plate is connected to the tension spring 344, and the scraper 342 is connected to one end of the bracket 341. The scraper 342 is in constant contact with the inner wall of the drainage ring plate 31. The flow guide 34 cleverly utilizes the impeller rotation power of the tower fan itself to drive the scraper 342 to intermittently scrape the bottom of the drainage ring plate 31. It requires no additional electric components, achieves self-cleaning flow guidance with zero power consumption, and eliminates poor drainage and wind resistance rebound caused by scale buildup, thus maintaining energy-saving effects throughout its entire life cycle.

[0036] A limiting track groove 3451 is formed on the limiting plate 345. One end of the bracket 341 passes through the limiting track groove 3451 and is connected to the impeller assembly 11 for transmission. The outer end of the rotating shaft of the impeller assembly 11 can be connected to a drive ring via a gearbox. The speed of the drive ring is changed by the gearbox. The outer wall of the drive ring is provided with a pressing plate, which contacts one end of the bracket 341 at a fixed position and pushes the bracket 341 to move along the limiting track groove 3451. The limiting track groove 3451 is elliptical, with its two ends being the end points of the reciprocating stroke. A guide block is provided at its end point. When the bracket 341 is in the limiting track groove When one end of 3451 is squeezed to the other end, the guide block and tension spring 344 cause the bracket 341 to return to its original position in the other limiting track groove 3451. When the bracket 341 moves within the two limiting track grooves 3451, the tilt of the bracket 341 is changed, thereby adjusting the scraper 342 to move down or up. When it moves down, the scraper 342 is attached to the inner wall of the drainage ring plate 31 to guide the water collected on the inner wall of the drainage ring plate 31 and quickly discharge it from the guide hole 311. When it is tilted up, the scraper 342 returns to its original position without affecting the water collection in the drainage ring plate 31.

[0037] By linking the limiting trajectory with the impeller drive, the downward scraping stroke and the upward return stroke of the scraper 342 alternate, which is efficient in scraping and has no resistance in the return stroke. This enables the continuous directional transport of wastewater and sediment to the guide hole 311, preventing the formation of a silt layer at the bottom of the hydrophobic ring plate 31 and causing blockage. As a result, the water-cooled baffle 2 is always in the state of optimal water flow and minimum wind resistance, realizing continuous energy saving based on wind power recovery and internal structural maintenance.

[0038] The guide component 34 directly utilizes the impeller's rotational power to drive the scraper 342 to reciprocate and scrape the hydrophobic ring plate 31 via the gearbox and limit track groove 3451. Without the need for an additional motor, it achieves rapid discharge of wastewater and impurities with zero additional energy consumption, preventing scale from clogging the air duct and ensuring low wind resistance and energy-saving operation throughout the equipment's entire life cycle.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
