Description

Technical Field

[0001] This invention relates to the field of fabric washing technology, and more particularly to a fabric drying and washing machine. Background Technology

[0002] With the accelerating pace of life and consumers' increasing demands for quality of life, fabric processing equipment with integrated washing and drying functions (such as washer-dryer combos) is gradually becoming the mainstream in the market. These devices, after completing the washing, rinsing, and dehydration processes, send hot air into the washing drum through a built-in drying system to achieve rapid drying of fabrics, meeting users' "wash and wear immediately" needs and greatly improving the convenience of life.

[0003] However, in existing washer-dryer combo technology, the air duct outlet structure of the drying system is generally fixed. Traditional drying devices mostly use fixed air outlets, which limits the direction of hot air delivery to a specific angle or a narrow range. In actual use, the distribution of fabrics inside the washing drum is often random and disordered as the drum rotates, potentially accumulating in different locations within the drum. Because the hot air angle cannot be adjusted, the fixed heat flow often only blows directly onto a specific area inside the drum, causing some fabrics to be difficult to dry completely due to uneven heating, while other fabrics may be damaged due to prolonged exposure to high temperatures. This uneven drying phenomenon not only reduces drying efficiency and increases energy consumption but also seriously affects user experience and the lifespan of fabrics. Summary of the Invention

[0004] The purpose of this invention is to provide a fabric drying and washing machine that solves the technical problems mentioned in the background section.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention discloses a fabric drying and washing integrated machine, comprising a casing, one end of which has a loading / unloading port, and an opening / closing door hinged to the outside of the loading / unloading port; an inner cylinder is rotatably disposed inside the casing, and an outer cylinder is sleeved on the outside of the inner cylinder, the axes of the inner cylinder and the outer cylinder being aligned, and both having an open structure at the end near the loading / unloading port; water permeable holes are evenly distributed on the peripheral wall of the inner cylinder, and the outer peripheral wall of the outer cylinder is fixedly connected to the inner wall of the casing by a plurality of support plates evenly arranged circumferentially; a mounting shaft aligned with the axis of the outer cylinder is rotatably disposed at the end of the outer cylinder away from the loading / unloading port, one end of the mounting shaft being fixedly connected to the inner cylinder, and the other end being connected to a washing electrode fixedly disposed on the inner wall of the casing. The machine is driven by a drive shaft; a water inlet pipe is fixedly installed on the upper part of the machine housing, and a drain pipe is installed on the lower part of the machine housing. The water inlet pipe and the drain pipe extend into the cavity between the outer cylinder and the inner cylinder, respectively. A hot air drying module is also installed inside the machine housing. An annular air duct is fixedly sleeved on the outer peripheral wall of the outer cylinder. The hot air drying module is connected to the annular air duct through a hot air supply pipe. Multiple air blowers connected to the annular air duct are evenly hinged along the circumference of the outer cylinder at the corresponding positions of the annular air duct. Multiple swinging mechanisms are installed on the inner peripheral wall of the outer cylinder to drive each air blower to reciprocate. A blowing nozzle is installed at the end of each air blower near the inner cylinder.

[0006] Furthermore, the inner circumference of the retrieval port is provided with a sealing ring that is compatible with the opening and closing door.

[0007] Furthermore, the drive shaft of the washing motor is provided with a driving pulley, and the other end of the mounting shaft is provided with a driven pulley. The driven pulley is connected to the driving pulley through a transmission belt.

[0008] Furthermore, the water inlet pipe is equipped with a water inlet valve, the drain pipe is equipped with a drain valve, and the hot air supply pipe is equipped with a hot air valve.

[0009] Furthermore, the hot air drying module includes a compressor, a condenser, an expansion valve, and an evaporator fixedly mounted on the inner wall of the casing. The compressor, condenser, expansion valve, and evaporator are connected sequentially via refrigerant pipelines. An air inlet connected to the condenser is provided at the top of the casing, and an induced draft fan is provided outside the air inlet. The condenser is connected to the annular air duct via the hot air supply pipeline. The upper part of the evaporator is connected to the cavity between the outer and inner cylinders via a return steam pipe, and a discharge pipe is provided at the bottom of the evaporator, extending to the outside of the casing.

[0010] Furthermore, a return steam valve is installed on the return steam pipe.

[0011] Furthermore, air passage holes are formed on the peripheral wall of the outer cylinder at the locations between each of the air blowers and the annular air duct, and a flexible corrugated pipe is connected between each air blower and its corresponding air passage hole.

[0012] Furthermore, each of the swing mechanisms includes a micro motor fixedly mounted on the inner wall of the outer cylinder. The drive shaft of the micro motor is connected to one end of a rotating rod, the other end of the rotating rod is hinged to one end of a connecting rod, and the other end of the connecting rod is hinged to an ear plate fixedly mounted on the outer wall of the corresponding blower pipe.

[0013] Furthermore, multiple protective boxes are fixedly installed on the inner wall of the outer cylinder, and each of the micro motors is respectively installed inside the protective box.

[0014] Furthermore, each of the micro motors has a drive bevel gear on its drive shaft, and a transmission shaft is rotatably mounted on the outer wall of each of the protective boxes. The end of the transmission shaft located inside the protective box has a driven bevel gear that matches the drive bevel gear. Each of the rotating rods is vertically and fixedly connected to the end of the transmission shaft located outside the protective box.

[0015] Compared with the prior art, the beneficial technical effects of the present invention are as follows: This invention, during fabric drying, uses multiple oscillating mechanisms to drive each blower pipe to oscillate back and forth, causing the direction of the hot air ejected from the blower nozzles to change in real time. This effectively covers all areas of the randomly distributed and constantly tumbling fabric within the inner drum. This allows hot air to penetrate the fabric from different directions, avoiding the problem of "over-drying areas and remaining wet in shaded areas" caused by fixed hot air. This ensures uniform drying of the entire drum of fabric and improves drying efficiency. Attached Figure Description

[0018] like Figures 1-5 As shown, a fabric drying and washing machine includes a housing 1. One end of the housing 1 has a loading / unloading port, and a hinged door 2 is mounted on the outside of the loading / unloading port. Additionally, a sealing ring 3, adapted to the hinged door, is provided on the inner circumference of the loading / unloading port. An inner cylinder 4 is rotatably mounted inside the housing 1, and an outer cylinder 5 is fitted around the outer cylinder 4. The inner cylinder 5 and the outer cylinder 5 are axially aligned, and both have an open structure at the end near the loading / unloading port 2.

[0019] The inner cylinder 4 has evenly distributed water-permeable holes 6 on its peripheral wall. The outer cylinder 5 is fixedly connected to the inner wall of the housing 1 by multiple support plates 7 evenly arranged along its circumference, meaning the outer cylinder 5 is fixedly installed inside the housing 1. A mounting shaft 8, aligned with the axis of the outer cylinder 5, is rotatably mounted at the end of the outer cylinder 5 away from the loading / unloading port. One end of the mounting shaft 8 is fixedly connected to the inner cylinder 5, meaning the inner cylinder 4 is rotatably installed inside the outer cylinder 5. The other end of the mounting shaft 8 is connected to the drive shaft of a washing motor 9 fixedly mounted on the inner wall of the housing 1. In this embodiment, a drive pulley 10 is mounted on the drive shaft of the washing motor 9, and a driven pulley 11 is mounted on the other end of the mounting shaft 8. The driven pulley 11 is connected to the drive pulley 10 via a transmission belt 12.

[0020] A water inlet pipe 13 is fixedly installed on the upper part of the housing 1, and a drain pipe 14 is fixedly installed on the lower part of the housing 1. The water inlet pipe 13 and the drain pipe 14 extend into the cavity between the outer cylinder 5 and the inner cylinder 4, respectively. In addition, a water inlet valve 15 is installed on the water inlet pipe 13, and a drain valve 16 is installed on the drain pipe 14. Both the water inlet valve 15 and the drain valve 16 are electrically controlled valves.

[0021] In this invention, during the washing operation of fabrics, the fabric to be washed and detergent are placed into the inner drum 4 through the loading and unloading port, and then the opening and closing door 2 is closed. The sealing ring 3 between the loading and unloading port and the opening and closing door 2 can prevent water leakage during the washing process. Then, the water inlet valve 15 is opened and the drain valve 16 is closed, and washing water is supplied through the water inlet pipe 13. The washing water enters the cavity between the outer drum 5 and the inner drum 4 and then enters the inner drum 4 through the water permeable hole 6 to come into contact with and mix with the fabric. At the same time, the washing motor 9 is turned on and drives the mounting shaft 8 and the inner drum 4 to rotate through belt drive. In this embodiment, the washing motor 9 is a variable frequency motor, which can drive the inner drum 4 to rotate clockwise and counterclockwise alternately, thereby completing the automatic washing operation of the fabric. After the washing operation is completed, the water inlet valve 15 is closed and the drain valve 16 is opened, and the excess washing water is discharged outward through the drain pipe 14. At this time, the washing motor 9 continues to drive the inner drum 4 to rotate, thereby realizing the centrifugal dehydration operation of the internal fabric.

[0022] The housing 1 is also equipped with a hot air drying module. An annular air duct 17 is fixedly fitted on the outer peripheral wall of the outer cylinder 5. The hot air drying module is connected to the annular air duct 17 through a hot air supply pipe 18. A heating air valve 19, which is an electrically controlled valve, is installed on the hot air supply pipe 18. Multiple air blowing pipes 20, which are connected to the annular air duct 17, are uniformly hinged along the circumference of the outer cylinder 5 at positions corresponding to the annular air duct 17. Specifically, air passage holes 21 are formed on the peripheral wall of the outer cylinder 5 at positions between each air blowing pipe 20 and the annular air duct 17. A flexible corrugated pipe 22 is connected between each air blowing pipe 20 and its corresponding air passage hole 21. Multiple swinging mechanisms are provided on the inner peripheral wall of the outer cylinder 5 to drive each air blowing pipe 20 to reciprocate. A blowing nozzle 23 is installed at the end of each air blowing pipe 20 near the inner cylinder 4.

[0023] After the fabric has finished dehydrating, the hot air drying module starts to generate hot air. After the hot air supply valve 19 is opened, the hot air generated by the hot air drying module is delivered to the annular air duct 19 through the hot air supply pipe 18, and then passes through the air passage 21, the flexible corrugated pipe 22 and the blowing pipe 20 in sequence, and finally sprayed out of the blowing nozzle 23 onto the fabric inside the drum. During this process, each swing mechanism drives the blowing pipe 20 and the blowing nozzle 23 to swing back and forth, so that the direction of the hot air blown out by the blowing nozzle 23 changes continuously. In conjunction with the washing motor driving the inner drum to rotate, the fabric is constantly turned over, so that the heat flow can cover a larger area, so that the fabric is heated evenly, improving the drying efficiency of the fabric and avoiding local overheating or incomplete drying.

[0024] In this embodiment, the hot air drying module includes a compressor 24, a condenser 25, an expansion valve 26, and an evaporator 27 fixedly installed on the inner wall of the housing 1. The compressor 24, condenser 25, expansion valve 26, and evaporator 27 are sequentially connected via a refrigerant pipeline 28, which is used to transfer refrigerant between the various components of the hot air drying module. An air inlet 29 connected to the condenser 25 is installed at the top of the housing 1, and an induced draft fan 31 is installed outside the air inlet 29. The condenser 25 is connected to the annular duct 17 via the hot air supply pipeline 18. The upper part of the evaporator 27 is connected to the cavity between the outer cylinder 5 and the inner cylinder 4 via a return steam pipe 32. A return steam valve 33, which is an electrically controlled valve, is installed on the return steam pipe 32. A discharge pipe 34 is connected to the bottom of the evaporator 27, extending to the outside of the housing 1. In addition, both the heating air valve 19 and the return steam valve 33 in this embodiment are one-way valves.

[0025] The working principle of the hot air drying module of the present invention is as follows: the compressor 24 compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gas and sends it into the condenser 25. At the same time, external air is introduced into the condenser 25 by the induced draft fan 31 and the air inlet 29. The high-temperature and high-pressure gaseous refrigerant liquefies and releases heat in the condenser, thereby heating the air entering the condenser 25. After being heated, the air is transmitted to the annular air duct 17 by the hot air supply pipeline 18 for drying the fabric. After being throttled by expansion valve 26, the pressure and temperature of the liquid refrigerant drop sharply, turning it into a low-temperature, low-pressure liquid refrigerant, which is then transported to evaporator 27. At the same time, the high-temperature hot air exchanges heat with the fabric in the inner cylinder, turning it into a steam-water mixture with a certain temperature (mixed with water vapor produced by the evaporation of moisture from the fabric). The low-temperature, low-pressure liquid refrigerant entering evaporator 27 exchanges heat with the steam-water mixture. The refrigerant absorbs the heat from the steam-water mixture and evaporates into a gaseous state. The water vapor in the steam-water mixture releases heat and condenses, then is discharged out through discharge pipe 34. The gaseous refrigerant returns to compressor 24, thus starting a new cycle. This cycle is repeated to achieve the hot air drying function.

[0026] In this embodiment, each of the swing mechanisms includes a micro motor 35 fixedly mounted on the inner wall of the outer cylinder 5. The drive shaft of the micro motor 35 is connected to one end of a rotating rod 36, and the other end of the rotating rod 36 is hinged to one end of a connecting rod 37. The other end of the connecting rod 37 is hinged to an ear plate 38 fixedly mounted on the outer wall of the corresponding blower pipe 20. Multiple protective boxes 39 are fixedly mounted on the inner wall of the outer cylinder 5, and each micro motor 35 is installed inside its respective protective box 39. By installing the micro motor 35 inside the protective box 39, contact between the micro motor 35 and the washing machine and water vapor can be effectively avoided, ensuring the working life of the micro motor 35. In addition, a drive bevel gear 40 is installed on the drive shaft of the micro motor 35, and a transmission shaft 41 is rotatably installed on the outer wall of each protective box 39. A driven bevel gear 42 adapted to the drive bevel gear 40 is installed at one end of the transmission shaft 41 inside the protective box 39. Each rotating rod 36 is vertically fixedly connected to the end of the transmission shaft 41 outside the protective box.

[0027] The working principle of the swing mechanism of the present invention is as follows: After the micro motor 35 is started, the micro motor 35 drives the rotating rod 36 to rotate through the meshing transmission action of the active bevel gear 40 and the driven bevel gear 42. During the rotation of the rotating rod 36, the blowing pipe 20 is driven to swing back and forth through the connecting rod 37, thereby continuously adjusting and changing the hot air blowing angle of the blowing nozzle 23 to increase the hot air coverage area.

[0028] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
