Description

Technical Field

[0001] This utility model relates to the field of drum washing machines, specifically a self-cleaning drum washing machine. Background Technology

[0002] Front-loading washing machines clean clothes by simulating hand washing through tumbling and kneading, resulting in less wear and tear. They typically offer multiple washing programs, such as wool wash and cotton / linen wash, to suit the needs of different fabrics. Front-loading washing machines also usually have higher spin speeds, resulting in higher drying efficiency. Due to their structural design, they use less water during the washing process, making them more energy-efficient and environmentally friendly. However, most current mainstream dryers lack lint filtration or use single / multi-layer filters to intercept lint. Existing products also have a dual-vortex self-cleaning function (vortex water flow blocks lint from entering the drying path). In summary, the shortcomings of existing technologies include blind spots in filtration (the filter can only intercept lint at the air inlet, and new lint that falls off during drying will directly enter the channel), lint residue (lint easily accumulates at the bends of the air duct), backflow contamination (negative pressure when the machine stops causes some lint to flow back into the washing drum with the airflow), and difficulty in maintenance (the air duct needs to be disassembled and cleaned). Therefore, we propose a self-cleaning front-loading dryer. Utility Model Content

[0003] The purpose of this utility model is to provide a self-cleaning drum washing machine, including a body, an outer drum inside the body, an inner drum rotatably installed inside the outer drum, a drying assembly inside the body, an openable and closable sealing door hinged to the opening of the body, a sealing gasket fixedly installed at the opening at the front end of the body, the sealing door contacting the sealing gasket, and a cleaning assembly assembled inside the body.

[0004] Preferably, the drying assembly includes a fan, which is disposed between the upper shell and the rear shell. The upper shell is connected to the lower shell. A heating tube is provided inside the upper shell. Temperature controllers are respectively installed on the upper shell and the lower shell. Temperature sensors are respectively installed on the lower shell and the rear shell. A flat water outlet is provided on the upper shell.

[0005] Preferably, the cleaning assembly includes a cleaning material box disposed within the machine body. The cleaning material box is connected to one outlet of a water pump via a pipe. The inlet of the water pump is connected to a tap water pipe. A rinsing pipe is connected between the cleaning material box and the inner cavity of the upper shell. The end of the rinsing pipe near the upper shell is connected to the upper shell via a flat water outlet. A condensate pipe is connected between the water pump and the rear shell.

[0006] Preferably, the lower shell has a through hole, and the through hole is aligned with the sealing gasket.

[0007] Preferably, the rear shell is provided with an air inlet, and the rear shell is connected to the inside of the cylinder through the air inlet.

[0008] Preferably, the inner wall of the rear shell is provided with multiple sets of protruding strips, the inner wall of the rear shell forms multiple sets of grooves through the multiple sets of protruding strips, and the inner wall of the rear shell is provided with a slope.

[0009] Preferably, the inner cylinder is fixedly connected to the drive end of the motor, and the motor is fixedly installed between the outer cylinder and the machine body.

[0010] Preferably, the cleaning material box is connected to a cleaning water injection pipe, and the lower end of the cleaning water injection pipe is connected to the inside of the cylinder.

[0011] Preferably, the bottom of the outer cylinder is connected to a drain pipe, and a water pump is installed on the drain pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In the daily washing process, this invention allows washing water to enter the upper shell cavity through a rinsing pipe. The water enters the upper shell cavity through a flat water outlet, which is designed to create a fan-shaped water flow. This allows some water to wash away lint from the through holes and sensors on the lower shell. This water also flows through the sealing gasket and along the inner glass wall of the sealing door to the space between the inner and outer drums, cleaning the sealing gasket and the inner glass wall of the sealing door. Finally, the water is drained outside the washing machine through the drain pipe. A portion of the water also washes away lint from the heating element and the lower shell. This invention solves the problem of automatically rinsing the front air duct and drying channel during daily washing, keeping the drying passage clean and preventing lint accumulation.

[0014] In the drying process, when the condensate water enters the rear shell through the condensate water pipe, the grooves and protrusions inside the rear shell disperse the water flow. The purpose of this is to increase the surface area after the water flow is dispersed, thereby increasing the heat exchange between the condensate water and the hot air and improving the drying efficiency. In addition, the waterfall-shaped water flow formed by the dispersed condensate water helps to block lint. Furthermore, after the waterfall water flows down the designed inclined surface, the splashing water droplets can also block lint. In addition, through a special design, the water flow in the rear condensate water channel forms a waterfall water curtain and splashing water mist, which doubly blocks lint at the air inlet, further reducing the amount of lint entering the drying channel.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 7 This utility model discloses a self-cleaning drum washing machine, comprising a body 1, an outer drum 2 inside the body 1, an inner drum 3 rotatably installed inside the outer drum 2, a drying assembly 4 inside the body 1, a hinged, openable and closable sealing door 5 at the opening of the body 1, a sealing gasket 7 fixedly installed at the opening at the front end of the body 1, the sealing door 5 contacting the sealing gasket 7, and a cleaning assembly 6 assembled inside the body 1.

[0025] The drying assembly 4 includes a fan 401, which is positioned between the upper shell 402 and the rear shell 403. The upper shell 402 is connected to the lower shell 408. A heating element 404 is installed inside the upper shell 402. Temperature controllers 405 are respectively installed on the upper shell 402 and the lower shell 408. Temperature sensors 406 are respectively installed on the lower shell 408 and the rear shell 403. A flat water outlet 407 is provided on the upper shell 402. During use, the temperature sensor 406 continuously measures the temperature and transmits the data to the temperature controller 405. The temperature controller 405 compares the feedback temperature value with the set value. If the temperature is lower than the target value, the temperature controller 405 closes the circuit and powers on the heating element 404 to heat the tube. Once the temperature reaches or exceeds the target temperature, the temperature controller disconnects the circuit and stops heating.

[0026] The cleaning assembly 6 includes a cleaning material box 601, which is disposed inside the body 1. The cleaning material box 601 is connected to one outlet of a water pump 602 via a pipe. The inlet of the water pump 602 is connected to a tap water pipe. A rinsing pipe 603 connects the cleaning material box 601 to the inner cavity of the upper shell 402. One end of the rinsing pipe 603 near the upper shell 402 is connected to the upper shell 402 via a flat water outlet 407. A condensate pipe 604 connects the water pump 602 to the rear shell 403. In use, the cleaning material box 601 can be opened, and an appropriate amount of laundry detergent or washing powder can be added into it. The water pump 602 can draw water from the tap water pipe into the cleaning material box 601. The water in the cleaning material box 601 can enter the inner cavity of the upper shell 402 through the rinsing pipe 603, and the cleaning water enters the inner cavity of the upper shell 402 through the flat water outlet 407.

[0027] The lower shell 408 is provided with a through hole, which is aligned with the sealing gasket 7. When air is discharged through the through hole, the discharged air enters the cylinder through the sealing gasket 7. When water is discharged through the through hole, the water flows through the sealing gasket 7 and along the inner glass wall of the sealing door 5 to the space between the inner and outer cylinders, which can clean the sealing gasket 7 and the inner glass wall of the sealing door 5.

[0028] The rear shell 403 is provided with an air inlet 8, and the rear shell 403 is connected to the inside of the cylinder through the air inlet 8; the air entering the inner cavity of the rear shell 403 is the high-humidity air inside the cylinder.

[0029] The inner wall of the rear shell 403 is provided with multiple sets of protruding strips 9, which form multiple sets of grooves. The inner wall of the rear shell 403 is also provided with an inclined surface. When condensate water enters the rear shell 403 through the condensate water pipe 604, the grooves and protruding structures inside the rear shell 403 disperse the water flow. The purpose of this is to increase the surface area after the water flow is dispersed, thereby increasing the heat exchange between the condensate water and the hot air and improving the drying efficiency. In addition, the waterfall-shaped water flow formed by the dispersed condensate water helps to block the lint. Furthermore, after the waterfall water flow falls onto the designed inclined surface, the splashing water droplets can also block the lint.

[0030] The inner drum 3 is fixedly connected to the drive end of the motor 10, and the motor 10 is fixedly installed between the outer drum 2 and the machine body 1. During the washing process, starting the motor 10 will drive the inner drum 3 to rotate, and the rotation of the inner drum 3 can wash the clothes. It is important to ensure that the motor 10 is waterproof when assembling the motor 10, the inner drum 3 and the outer drum 2. Since this is the existing technology, it will not be described in detail here.

[0031] The cleaning material box 601 is connected to a cleaning water injection pipe 11, the lower end of which is connected to the inside of the drum. When washing clothes, the clothes are placed in the inner drum 3, the sealing door 5 is closed, and water flows through the cleaning material box 601. The water flows through the cleaning material box 601 and mixes with the laundry detergent or washing powder inside the cleaning material box 601. Then, the water is injected together through the cleaning water injection pipe 11 between the inner drum 3 and the outer drum 2, so that the cleaning water mixes with the clothes. Under the action of the motor 10 driving the inner drum 3 to rotate, the clothes can be effectively cleaned.

[0032] The bottom of the outer cylinder 2 is connected to a drain pipe 12, and a water pump is installed on the drain pipe 12. When the clothes are spun dry after washing, the water pump and the drain pipe 12 are used to completely pull out the inner cylinder 3 and the outer cylinder 2 and discharge them into the sewer.

[0033] The working principle of this utility model is as follows: When washing clothes, the clothes are placed in the inner drum 3, the sealing door 5 is closed, and the water flows through the washing material box 601. The water will mix with the laundry detergent or washing powder inside the washing material box 601, and then be injected together through the washing water injection pipe 11 between the inner drum 3 and the outer drum 2, so that the washing water and the clothes are mixed together. Under the action of the motor 10 driving the inner drum 3 to rotate, the clothes can be effectively washed.

[0034] During routine clothing washing, some of the water inside the washing cartridge 601 enters the inner cavity of the upper shell 402 through the rinsing pipe 603, and the washing water enters the inner cavity of the upper shell 402 through the flat water outlet 407.

[0035] The flat water outlet 407 is designed to be flat, so that the water outlet shape is fan-shaped. This allows some water to wash the through holes and wire debris on the sensor in the lower shell 408. This water flows through the sealing gasket 7 and along the inner glass wall of the sealing door 5 to the space between the inner and outer drums, which can clean the sealing gasket 7 and the inner glass wall of the sealing door 5. Then the water is discharged to the outside of the washing machine through the inlet and outlet pipes 12. Some water also washes the heating tube 404 and the wire debris inside the lower shell 408.

[0036] After cleaning, during the drying process, the water pump 10 draws water from the tap water pipe into the condensate pipe 604 instead of the cleaning material box 601. It should be noted that the water pump 10 has a dual outlet, and both outlets are equipped with control valves for drainage. Simultaneously, as condensate is injected into the rear shell 403 through the condensate pipe 604, the fan 401 and heating element 404 are activated. Under the action of the fan 401, and with the air inlet 8 connected to the inside of the cylinder, the air entering the inner cavity of the rear shell 403 is high-humidity air from inside the cylinder. As the air flows along the rear shell 403 and the upper shell 402... The air is heated by the heating tube 404, and the heated high-temperature air is discharged through the through hole on the lower shell 408. The discharged high-temperature air enters the cylinder through the sealing gasket 7 for drying. During this drying process, when the condensate water enters the rear shell 403 through the condensate water pipe 604, the groove and protrusion structure inside the rear shell 403 disperses the water flow. The purpose of this is to increase the surface area after the water flow is dispersed, thereby increasing the heat exchange between the condensate water and the hot air and improving the drying efficiency. In addition, the waterfall-shaped water flow formed by the dispersed condensate water helps to block the lint. Furthermore, after the waterfall water flow falls onto the designed inclined surface, the splashing water droplets can also block the lint.

[0037] It should be noted that each electrical component in this utility model requires an external power supply during use, and the washing machine of this utility model is equipped with a control system. This control system is usually composed of a microcontroller (such as a microprocessor or microcomputer chip), which is responsible for adjusting various functions such as washing program, temperature, spin speed, and water level. It monitors the status of the washing machine (such as water level, temperature, and spin speed) through sensors, and automatically controls the operation of components such as motor, heater, valve and pump according to the preset program, thereby realizing an intelligent washing process.

[0038] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
