[0002] With the improvement of people's living standards, washing machines have become an essential household appliance, and their functions are gradually developing towards intelligence and multi-functionality, such as integrating washing, drying, and care functions. However, existing drum washing machines still have the following problems in actual use: Insufficient drying efficiency: The hot air delivery path of traditional drying components is not designed properly, and the hot air is easily dispersed or blown directly onto the drum wall, resulting in uneven drying of clothes, longer drying time, and low heat energy utilization.

[0003] Unstable door seal performance: Door seal components are easily aged, deformed or not sealed properly due to long-term exposure to humid environment, temperature changes and frequent opening and closing, resulting in water leakage, hot air leakage, and even affecting the service life of the washing machine.

[0004] Low accuracy of care solution dispensing: Traditional care solution dispensers often rely on gravity or simple valve control, which can easily lead to over-dispensing, residue, or leakage, resulting in waste or poor washing effect.

[0005] Insufficient structural reliability: The connection structure between the door seal assembly and the drying system, and between the care solution box and the outer barrel is complex and requires high assembly precision. After long-term use, the connection is prone to loosening due to vibration, corrosion, etc., which affects the overall performance.

[0006] To address the aforementioned issues, this invention proposes an intelligent drum washing machine that integrates efficient drying, reliable sealing, and precise care functions. By optimizing the door seal structure, the airflow guidance for drying, and the care liquid dispensing system, the overall performance of the washing machine is improved. Utility Model Content

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] like Figure 1-5 As shown in the figure, this embodiment discloses an intelligent drum washing machine.

[0031] Specific reference Figure 1 As shown, it includes a housing 100 and a roller assembly 200 disposed inside the housing 100. The roller assembly 200 includes an inner drum 210 and an outer drum 220 arranged concentrically, and the outer drum 220 is fixed inside the housing 100, while the inner drum 210 can rotate inside the outer drum 220. The front opening of the roller assembly 200 forms a clothing placement inlet, and a door seal assembly 300 is provided on the edge of the opening; a drying assembly 400 is provided at the upper end of the roller assembly 200, and the air outlet 401 of the drying assembly 400 extends to the door seal assembly 300, and an air inlet 301 is provided on the door seal assembly 300 and communicates with the air outlet 401. The door seal assembly 300 includes a steel ring 310 and a sealing ring 320 integrally formed by injection molding. The steel ring 310 is rigidly connected to the drying assembly 400, and the steel ring 310 is provided with an air guide part 311 to guide the hot air blown out of the air outlet 401 to the middle of the inner barrel 210. A door 1 is hinged to the outer casing 100, and the door 1 and the door sealing assembly 300 are sealed together.

[0032] The above is the basic scheme of this embodiment.

[0033] The outer casing 100 is designed as a shell structure with an opening on its front end. The roller assembly 200 is installed inside the outer casing 100, and its front opening is perfectly aligned with the opening of the outer casing 100, forming a garment placement inlet. Garments can be placed into the washing chamber of the roller assembly 200 through this inlet for washing. One side of the door 1 is hinged to the outer casing 100, while the other side can be opened outwards for easy access to garments. During the washing process, since a large amount of water exists in the washing chamber, the garment placement inlet must be reliably sealed and have a good seal to prevent water from overflowing from the opening. Therefore, a special door seal assembly 300 is provided at the edge of the garment placement inlet. This assembly fits tightly with the door 1 to achieve an effective seal.

[0034] In this embodiment, a drying assembly 400 is also provided. This assembly can deliver hot air to the washing chamber of the drum assembly 200, thereby drying the clothes that have already undergone spin-drying and improving the efficiency of the overall washing process. The drum assembly 200 includes a rotatable inner tub 210 and a fixed outer tub 220. The inner tub 210 can rotate relative to the outer tub 220 under the action of a driving component, while the outer tub 220 is fixedly installed inside the outer casing 100. The door seal assembly 300 is installed on the outer tub 220 and does not move with the rotation of the inner tub 210, thereby ensuring a stable and reliable seal between the drum assembly 200 and the door 1. Furthermore, the hot air outlet channel 401 of the drying assembly 400 is connected to the door seal assembly 300 to ensure the consistency of the air outlet position, enhance the concentration and effectiveness of the drying airflow, and improve the thermal energy utilization efficiency.

[0035] In actual use, the sealing ring 320 in the door seal assembly 300, which connects to the door body 1, is made of flexible and durable rubber, which can adapt to the deformation caused by frequent opening and closing of the door body 1 to achieve a sealing effect. At the same time, in order to ensure the stability of the door seal assembly 300 installed on the roller assembly 200 and to avoid unstable connection between the door seal assembly 300 and the roller assembly 200 due to deformation of the sealing ring 320, a rigid steel ring 310 is provided on the sealing ring 320 and fixed to the roller assembly 200. The sealing ring 320 can be removed from the steel ring 310 for replacement or cleaning.

[0036] In this embodiment, the steel ring 310 and the sealing ring 320 are fixed by a conventional snap-fit ​​connection in the prior art, which will not be described in detail here.

[0037] The door seal assembly 300 is located at the clothing inlet. To ensure that hot air can be blown into the washing chamber, an air guide part 311 is provided on the door seal assembly 300. The air guide part 311 is a protrusion on the inner wall of the steel ring 310, and the end face of the air guide part 311 facing the air inlet 301 is set as an inclined surface.

[0038] Specific reference Figure 2 Hungry Figure 3 As shown, the air guide portion 311 is formed on the steel ring 310 structure. The upper part of the steel ring 310 has an air inlet 301 that perfectly matches the shape of the outlet of the air outlet channel 401. This air inlet 301 and the air outlet channel 401 form a seamless airflow guiding system. Specifically, the air guide portion 311 is located below the air inlet 301. It is designed by protruding a portion of the surface of the steel ring 310 towards the inside of the cleaning chamber, forming a special structure with a guiding function. The upper surface of the air guide portion 311, i.e., the contact surface facing the air inlet 301, is set as an inclined surface with a certain angle, forming the air guide surface 311.1. This inclined air guide surface 311.1 can effectively change the airflow direction, redirecting the originally vertically downward-flowing hot air, allowing it to flow precisely along a preset trajectory to the center area of ​​the inner tub 210, thereby ensuring optimal distribution of hot air within the cleaning chamber.

[0039] Furthermore, the protruding design of the air guide section 311 not only optimizes the airflow path but also further enhances the overall structural strength of the door seal assembly 300. This design allows the steel ring 310 to better maintain its shape stability under external pressure, preventing deformation caused by long-term use. Simultaneously, the surface of the air guide section 311 undergoes special treatment, providing a certain degree of corrosion resistance and wear resistance to meet the long-term usage requirements of the humid environment inside the washing machine.

[0040] To improve the efficiency of hot air utilization, the tilt angle of the air guide section 311 has been repeatedly tested and adjusted to ensure a stable airflow guidance effect under different wind speed conditions. This design also effectively reduces energy loss of airflow during transmission, allowing hot air to cover the clothes in the washing chamber more quickly and evenly, thereby shortening drying time and improving drying quality.

[0041] In this embodiment, the drying assembly 400 includes a fan 420 and an air duct 410. An air outlet ring 411 is provided at the edge of the air outlet of the air duct 410, and the outer diameter of the air outlet ring 411 is smaller than the outer diameter of the air duct 410. The steel ring 310 is provided with a connecting part 312 that can surround the air outlet ring 411.

[0042] Specific reference Figure 3 As shown, the air duct 410 adopts a conventional pipe structure design, and its output end has an air outlet ring 411 that protrudes slightly from the end along the air outlet direction. The outer wall of the air outlet ring 411 forms an annular groove structure with the outer wall of the main body of the air duct 410. At the same time, on the steel ring 310 located on the side of the air inlet 301, a connecting part 312 with a shape that perfectly matches the aforementioned annular groove is provided.

[0043] Through this design, the connecting part 312 can tightly and completely wrap around the entire outer surface of the air outlet ring 411, thus achieving a seamless connection. This structure ensures that during the operation of the washing machine, the hot airflow can flow smoothly along the internal channel of the air duct 410 and be directly delivered to the air outlet, effectively avoiding any gas leakage or energy loss caused by assembly gaps, and improving the system's sealing and thermal efficiency.

[0044] In this embodiment, the air outlet of the fan 420 is provided with a heating element 430. The airflow passes through the heating element 430 to form hot air, which is then transported along the air outlet channel 401 in the air duct 410.

[0045] Frequent opening and closing of the door 1 can easily cause wear on the sealing ring 320. Additionally, during the washing machine's operation, continuous vibration can lead to unstable connections between the sealing ring 320 and the door panel. (See details...) Figure 4 As shown, in this embodiment, the sealing ring 320 includes a rubber outer ring 321 and a metal inner ring 322 embedded in the rubber outer ring 321. The metal inner ring 322 is integrally formed inside the rubber outer ring 321 by injection molding.

[0046] Preferably, the inner metal ring 322 is a nickel-titanium alloy shape memory metal, and the outer wall of the inner metal ring 322 is coated with a fluororubber coating.

[0047] Nickel-titanium shape memory alloy is a special alloy material with unique shape memory function. When the external temperature reaches a certain critical value, it can automatically restore the plastic deformation generated at low temperature to its original shape. This characteristic makes this type of alloy not only have excellent shape memory effect, but also good plasticity and mechanical properties.

[0048] At room temperature, the inner metal ring 322, made of nickel-titanium shape memory alloy, is in a relatively relaxed state. This allows it to cause the connected outer rubber ring 321 to expand outwards moderately, ensuring the entire sealing structure remains fully fitted to the surface of the door body 1, achieving a reliable static seal. During the drying and heating process, as the temperature of the outer rubber ring 321 gradually rises, the inner metal ring 322 undergoes a phase change due to heat, resulting in contraction. This actively drives the sealing ring 320 to adhere more tightly to the connection point of the door body 1, forming a continuously following, dynamic clamping seal mechanism that effectively adapts to changes in structural dimensions caused by temperature variations.

[0049] Preferably, a fluororubber coating is applied to the outer surface of the metal inner ring 322. This coating significantly increases the coefficient of friction between the metal inner ring 322 and the rubber outer ring 321, preventing unnecessary relative sliding between them due to insufficient friction when the washing machine vibrates during operation. This maintains the stability of the sealing ring 320's shape, preventing unintended deformation and thus improving the reliability and durability of the overall sealing structure.

[0050] In this embodiment, a sensor 2 is provided on the rubber outer ring 321. The probe of the sensor 2 extends into the interior of the rubber outer ring 321 and contacts the metal inner ring 322 to detect the temperature of the metal inner ring 322.

[0051] In the specific structure of this embodiment, a high-sensitivity temperature sensor 2 is integrated and installed on the rubber outer ring 321. The precision probe of the sensor 2 extends through the rubber material layer into its internal area and makes direct contact with the surface of the inner metal ring 322, thereby realizing real-time monitoring of the temperature of the inner metal ring 322.

[0052] The miniature sensor 2 can be embedded inside the rubber outer ring 321 or fixed to the outer surface of the rubber outer ring 321. Depending on the actual measurement requirements, multiple sensor units 2 can be arranged at intervals in the circumferential direction to obtain more comprehensive temperature distribution data. The detection end of each sensor 2 is tightly connected to the substrate of the metal inner ring 322 through a high thermal conductivity adhesive material to minimize thermal resistance and ensure the shortest heat transfer path and the fastest response.

[0053] By continuously monitoring the temperature of the rubber outer ring 321 or the metal inner ring 322 using the deployed sensor system 2, the phase change triggering state of the nickel-titanium shape memory alloy component can be accurately monitored, effectively ensuring its operational accuracy and response reliability, and thus providing an accurate basis for judgment on the operation, maintenance or timely replacement of the sealing ring 320.

[0054] To prevent the microsensor 2 from being damaged by heat, a heat insulation layer can be provided between the microsensor 2 and the rubber outer ring 321.

[0055] In this embodiment, the outer shell 100 is further provided with a care solution box assembly 500. The care solution box assembly 500 includes an outer box 510 fixed at the upper opening of the outer shell 100, and an inner box 520 that can be removed and disposed inside the outer box 510. The upper liquid outlet of the outer box 510 and the lower liquid outlet 561 of the outer box 510 are connected by a one-way valve assembly 530. The bottom of the outer box 510 is equipped with a peristaltic pump 540. The tubing that delivers the nursing solution passes through the peristaltic pump 540 to quantitatively dispense the nursing solution into the roller assembly 200.

[0056] The top of the outer casing 100 is provided with an opening for accommodating the outer box 510. The outer box 510 is a base structure with an opening at the top and is inserted into the outer casing 100 and fixed through the opening. The bottom of the outer box 510 is provided with a lower liquid outlet 561, which is connected to the roller assembly 200 through a pipe.

[0057] The peristaltic pump 540 pumps fluid by alternately squeezing and releasing the pump's flexible delivery hose.

[0058] The peristaltic pump 540 is fixed at the bottom of the outer box 510. The tubing passes through the peristaltic pump 540, and the peristaltic pump 540 controls the delivery of the nursing solution, thereby realizing the quantitative delivery of the nursing solution.

[0059] The inner box 520 is a detachable box body. The opening on the upper end is closed by a lid, and its shape matches the groove of the outer box 510, so it can be inserted into the outer box 510. The bottom of the inner box 520 is provided with a liquid outlet pipe 521. The liquid outlet of the liquid outlet pipe 521 is the upper liquid outlet, which is connected to the lower liquid outlet 561 of the outer box 510 through a one-way valve structure.

[0060] When the inner box 520 is removed from the outer box 510, the liquid outlet tube 521 is closed, and the nursing solution in the inner box 520 cannot overflow from the upper liquid outlet. When the inner box 520 is installed into the outer box 510, the pin on the outer box 510 pushes open the one-way valve structure, so that the liquid outlet tube 521 and the lower liquid outlet 561 are connected to allow liquid to be dispensed.

[0061] The one-way valve structure in this embodiment is consistent with the conventional one-way valve structure in the prior art, and will not be described in detail here.

[0062] The bottom of the outer box 510 is provided with a clearance hole 511. A sealing gasket 550 is embedded on the outer periphery of the clearance hole 511, and a mating rib 551 extends toward the center of the clearance hole 511. The mating rib 551 and the liquid outlet pipe 521 of the inner box 520 are interference-fitted.

[0063] Specific reference Figure 5 As shown, the liquid outlet pipe 521 at the lower end of the inner box 520 extends into the clearance hole 511, forming a gap between it and the clearance hole 511. A groove is formed on the lower end face of the outer shell 100 around the clearance hole 511. The sealing gasket 550 is embedded in the groove. Furthermore, the mating rib 551 is located below the groove and extends radially along the clearance hole 511, extending into the gap between the liquid outlet pipe 521 and the clearance hole 511. Its end is press-fitted with the liquid outlet pipe 521 to seal the clearance hole 511.

[0064] This design effectively prevents liquid leakage from the clearance hole 511, ensuring the equipment's sealing performance. Simultaneously, the interference fit makes the assembly more stable, ensuring a tight connection even during vibrations during washing machine operation. Furthermore, the use of the sealing gasket 550 further enhances the sealing effect, providing reliable assurance for the normal operation of the washing machine.

[0065] The bottom of the outer box 510 is located at the liquid outlet cover 560, and the lower liquid outlet 561 is located on the liquid outlet cover 560; the sealing gasket 550 is located between the liquid outlet cover 560 and the outer box 510.

[0066] The bottom of the outer box 510 is equipped with a dedicated liquid outlet cap 560, which is firmly fixed to the bottom of the outer box 510 with screws to ensure the stability of the overall structure. A sealing gasket 550 is provided between the contact surfaces of the liquid outlet cap 560 and the outer box 510. The gasket is tightly clamped between the two and plays a crucial sealing role, effectively preventing liquid leakage.

[0067] Meanwhile, the dispensing tube 521 passes through the pre-set clearance hole 511 and extends precisely into the internal space of the dispensing cap 560, communicating with the lower dispensing port 561 located at the bottom of the dispensing cap 560. This design forms a complete and smooth output path, enabling the care solution to be reliably delivered from inside the container to the external point of use, ensuring the realization of product functions and ease of use.
