Abstract
Description
Technical Field
[0001] The present invention relates to the field of drum washing machines, and specifically to a drying self-cleaning drum washing machine. Background Art
[0002] Drum washing machines wash clothes by simulating the beating and rubbing methods of hand washing, causing less wear and tear on clothes. They usually have a variety of washing programs, such as wool wash, cotton and linen wash, etc., to meet the needs of different fabrics. Drum washing machines usually also have a higher dehydration speed, and the clothes drying efficiency is higher. Due to their structural design, drum washing machines use less water during the washing process, which is more energy-saving and environmentally friendly; existing mainstream drying washing machines generally do not have a function of filtering lint or use a single-layer / multi-layer filter screen to intercept lint, and there is a double-vortex self-cleaning function in existing products (vortex water flow blocks lint from entering the drying path). Generally speaking, the defects of the existing technology include filtering blind spots (the filter screen can only intercept the lint at the air inlet, and the new lint shed during the drying process will directly enter the channel), lint residue (lint is easily left and piled up at the bent part of the air duct), reverse pollution (negative pressure during shutdown will cause some lint to flow back into the washing drum with the air flow), and difficult maintenance (the air duct needs to be disassembled and cleaned). Therefore, we propose a drying self-cleaning drum washing machine. Summary of the Invention
[0003] The purpose of the present invention is to provide a drying self-cleaning drum washing machine, including a machine body. An outer cylinder is arranged inside the machine body, an inner cylinder is rotatably installed inside the outer cylinder, a drying component is arranged inside the machine body, a seal door that can be opened and closed is hinged to the open end of the machine body, a sealing gasket is fixedly installed at the open end of the front end of the machine body, the seal door contacts the sealing gasket, and a cleaning component is assembled inside the machine body.
[0004] Preferably: The drying component includes a blower, the blower is arranged between the upper shell and the rear shell, the upper shell is connected to the lower shell, a heating tube is arranged inside the upper shell, temperature controllers are respectively assembled on the upper shell and the lower shell, temperature sensors are respectively assembled on the lower shell and the rear shell, and a flat water outlet is arranged on the upper shell.
[0005] Preferably: The cleaning component includes a cleaning material box, the cleaning material box is arranged inside the machine body, the cleaning material box is connected to one water outlet end of a water pump through a pipeline, the water inlet end of the water pump is externally connected to a tap water pipeline, a flushing pipeline is connected between the cleaning material box and the inner cavity of the upper shell, one end of the flushing pipeline close to the upper shell is mutually communicated with the upper shell through the flat water outlet, and a condensation water pipe is connected between the water pump and the rear shell.
[0006] Preferably: A through hole is arranged on the lower shell, and the through hole is aligned with the sealing gasket.
[0007] Preferably: An air inlet is arranged on the rear shell, and the rear shell is connected to the inside of the connecting cylinder through the air inlet.
[0008] Preferably, a plurality of raised strips are provided on the inner wall of the rear shell. A plurality of grooves are formed on the inner wall of the rear shell through the plurality of raised strips, and an inclined surface is provided on the inner wall of the rear shell.

[0011] Preferably, a drain pipe is connected to the bottom of the outer cylinder, and a water pump is assembled on the drain pipe.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: During the daily clothes washing process of the present invention, cleaning water enters the inner cavity of the upper shell through the flushing pipeline, and the cleaning water enters the inner cavity of the upper shell through the flat-shaped water outlet. The flat-shaped water outlet is designed to be flat, so that the water outlet shape is fan-shaped, which can make a part of the water flow flush the through holes provided on the lower shell and the lint on the sensor, and this water flow passes through the sealing gasket and flows along the glass inner wall of the sealing door to the space between the inner and outer cylinders, which can clean the sealing gasket and the glass inner wall of the sealing door, and then is discharged outside the washing machine through the drain pipe. Another part of the water flow flushes the heating pipe and the lint in the lower shell, thus solving the problem that the front air duct and the drying channel can be automatically flushed during daily washing, keeping the drying path clean, and avoiding the problem of lint accumulation.
[0013] When the present invention is working for drying, when the condensed water starts to enter the rear shell through the condensate pipe, there are grooves and raised structures in the rear shell to disperse the water flow. The purpose is that after the water flow is dispersed, the area increases, which increases the heat exchange between the condensed water and the hot air and improves the drying efficiency; there is also a waterfall-shaped water flow formed by the dispersed and falling condensed water to block the lint, and after the waterfall water flow falls onto the designed inclined surface, the splashing water droplets can also block the lint; furthermore, through the special design, the water flow in the rear-end condensate water path forms a waterfall water curtain and splashing water mist, which double-blocks the lint at the air inlet, further reducing the lint entering the drying channel.

Specific implementation mode
[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0017] Refer to Figure 1 - Figure 7 A drying and self-cleaning drum washing machine of the present invention includes a machine body 1. An outer cylinder 2 is arranged inside the machine body 1. An inner cylinder 3 is rotatably installed inside the outer cylinder 2. A drying component 4 is arranged inside the machine body 1. A sealing door 5 that can be opened and closed is hingedly installed at the open end of the machine body 1. A sealing gasket 7 is fixedly installed at the open end of the front end of the machine body 1. The sealing door 5 contacts the sealing gasket 7. A cleaning component 6 is assembled inside the machine body 1.
[0018] The drying component 4 includes a fan 401. The fan 401 is arranged between the upper shell 402 and the rear shell 403. The upper shell 402 is connected to the lower shell 408. A heating pipe 404 is arranged inside the upper shell 402. Thermostats 405 are respectively assembled on the upper shell 402 and the lower shell 408. Temperature sensors 406 are respectively assembled on the lower shell 408 and the rear shell 403. A flat water outlet 407 is arranged on the upper shell 402; when in use, the temperature sensor 406 continuously measures the temperature and transmits the data to the thermostat 405. The thermostat 405 compares the feedback temperature value with the set value. If the temperature is lower than the target value, the thermostat 405 closes the circuit and energizes the heating pipe 404 to heat. Once the temperature reaches or exceeds the target temperature, the thermostat disconnects the circuit and stops heating.
[0019] The cleaning component 6 includes a cleaning material box 601, which is arranged inside the machine body 1. The cleaning material box 601 is connected to an outlet end of a water pump 602 through a pipeline. The inlet end of the water pump 602 is externally connected to a tap water pipeline. A flushing pipeline 603 is connected between the cleaning material box 601 and the inner cavity of the upper shell 402. One end of the flushing pipeline 603 close to the upper shell 402 communicates with the upper shell 402 through a flat-shaped water outlet 407. A condensate water pipe 604 is connected between the water pump 602 and the rear shell 403. When in use, the cleaning material box 601 can be opened, and an appropriate amount of laundry detergent or washing powder can be put into the cleaning material box 601. The water pump 602 can be used to pump the water in the tap water pipeline 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 flushing pipeline 603, and the cleaning water enters the inner cavity of the upper shell 402 through the flat-shaped water outlet 407.
[0020] The lower shell 408 is provided with through holes, and the through holes are aligned with the sealing gasket 7. When the air is discharged through the through holes, the discharged air enters the cylinder through the sealing gasket 7. When the water is discharged through the through holes, the water flows through the sealing gasket 7 and along the glass inner wall of the sealing door 5 to the space between the inner and outer cylinders, and the sealing gasket 7 and the glass inner wall of the sealing door 5 can be cleaned.
[0021] 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 inlet 8 is connected to the inside of the cylinder, and the high-humidity air in the cylinder enters the inner cavity of the rear shell 403.
[0022] The inner wall of the rear shell 403 is provided with multiple groups of raised strips 9. Multiple groups of grooves are formed on the inner wall of the rear shell 403 through the multiple groups of raised strips 9, and the inner wall of the rear shell 403 is provided with an inclined surface. When the condensate water starts to enter the rear shell 403 through the condensate water pipe 604, the grooves and raised structures in the rear shell 403 disperse the water flow. The purpose is that after the water flow is dispersed, the area increases, which increases the heat exchange between the condensate water and the hot air and improves the drying efficiency. There is also a waterfall-shaped water flow formed by the dispersed condensate water falling, which can play a role in blocking lint. And after the waterfall water flow falls onto the designed inclined surface, the splashing water droplets can also block lint.
[0023] The inner cylinder 3 is fixedly connected to the driving end of the motor 10, and the motor 10 is fixedly installed between the outer cylinder 2 and the machine body 1. During the process of washing clothes, starting the motor 10 will drive the inner cylinder 3 to rotate, and the rotation of the inner cylinder 3 can wash the clothes. It should be noted that when assembling the motor 10, the inner cylinder 3 and the outer cylinder 2, attention should be paid to the waterproofing of the motor 10. Since this is the prior art, it will not be described in detail here.
[0024] A cleaning water injection pipe 11 is connected to the cleaning material box 601, and the lower port of the cleaning water injection pipe 11 is connected to the inside of the cylinder; when washing clothes, the clothes are put into the inner cylinder 3, the sealing door 5 is closed, water flows through the cleaning material box 601, and the water will be mixed with the laundry detergent or washing powder inside the cleaning material box 601, and then they are injected into the space between the inner cylinder 3 and the outer cylinder 2 together through the cleaning water injection pipe 11, so that the cleaning water is mixed with the clothes. Under the action of the motor 10 driving the inner cylinder 3 to rotate, the clothes can be effectively washed.
[0025] A drain pipe 12 is connected to the bottom of the outer cylinder 2, and a water pump is installed on the drain pipe 12; when drying the clothes after washing, through the water pump and the drain pipe 12, all the water between the inner cylinder 3 and the outer cylinder 2 is pumped out and discharged into the sewer.
[0026] The working principle of the present invention: when washing clothes, the clothes are put into the inner cylinder 3, the sealing door 5 is closed, water flows through the cleaning material box 601, and the water will be mixed with the laundry detergent or washing powder inside the cleaning material box 601, and then they are injected into the space between the inner cylinder 3 and the outer cylinder 2 together through the cleaning water injection pipe 11, so that the cleaning water is mixed with the clothes. Under the action of the motor 10 driving the inner cylinder 3 to rotate, the clothes can be effectively washed; During the daily process of washing clothes, a part of the water inside the cleaning material box 601 will enter the inner cavity of the upper shell 402 through the flushing pipe 603, and the cleaning water enters the inner cavity of the upper shell 402 through the flat-shaped water outlet 407. The flat-shaped water outlet 407 is designed to be flat, so that the water outlet shape is fan-shaped, which can make a part of the water flow flush the through holes provided on the lower shell 408 and the lint on the sensor. And this water flow passes through the sealing gasket 7 and flows along the glass inner wall of the sealing door 5 to the space between the inner and outer cylinders, which can clean the sealing gasket 7 and the glass inner wall of the sealing door 5, and then enters the drain pipe 12 and is discharged outside the washing machine. Another part of the water flow flushes the heating pipe 404 and the lint inside the lower shell 408; After the cleaning is completed and the drying work is carried out, when the water pump 10 pumps the water in the tap water pipe, the water will enter the condensate pipe 604 instead of the cleaning cartridge 601. Here, it should be noted that the water outlet end of the water pump 10 is provided with a double outlet and control valves are installed at both water outlets for drainage; while the condensate pipe 604 injects condensate water into the rear shell 403, the fan 401 is started to work, and the heating pipe 404 is started to heat. Under the action of the fan 401, and inside the air inlet 8 connecting cylinder, the air entering the inner cavity of the rear shell 403 is the high-humidity air in the cylinder. When the air flows along the rear shell 403 and the upper shell 402, it will be heated by the heating pipe 404, and the heated high-temperature air is discharged through the through holes on the lower shell 408, and the discharged high-temperature air enters the cylinder through the gasket 7 to carry out the drying work; during this drying process, when the condensate water starts to enter the rear shell 403 through the condensate pipe 604, there are grooves and convex structures in the rear shell 403 to disperse the water flow. The purpose is that after the water flow is dispersed, the area increases, which increases the heat exchange between the condensate water and the hot air and improves the drying efficiency; in addition, the waterfall-shaped water flow formed by the dispersed and falling condensate water can play a role in blocking lint, and after the waterfall water flow falls onto the designed inclined plane, the splashing water droplets can also block lint.
[0027] It should be noted that each electrical component in the present invention needs an external power supply during use, and the washing machine of the present invention is equipped with a control system. This control system usually consists of a microcontroller (such as a microprocessor or a microcomputer chip), which is responsible for adjusting various functions such as washing programs, temperature, rotation speed, water level, etc. It monitors the state of the washing machine (such as water level, temperature, rotation speed) through sensors, and automatically controls the operation of components such as motors, heaters, valves, and pumps according to the preset programs, so as to realize an intelligent washing process.
[0028] The above content is a further detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present invention.
