Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and more specifically, to a clothing processing device. Background Technology

[0002] Clothing handling equipment, such as washing machines and washer-dryer combos, can accumulate detergent residue, clothing fibers, sebum, mineral scale, and various bacteria and molds in areas like the space between the inner and outer drums, the outer wall of the inner drum, and the door seal during long-term use. This grime not only produces unpleasant odors and affects the cleanliness and hygiene of washed clothes, but it can also breed harmful bacteria, posing a potential threat to the user's health. Therefore, the self-cleaning function of clothing handling equipment has become an important requirement for modern home appliances.

[0003] Research has revealed that dirt easily accumulates on the inner wall of the outer drum of front-loading washing machines because most washing machines on the market lack a dedicated design for cleaning the inner drum. As the washing machine is used more frequently and over the years, stains accumulate over time without being cleaned, directly affecting the quality of laundry.

[0004] Most washing machines on the market lack separate cleaning mechanisms for the inner and outer drums. This often results in ineffective cleaning of the inner drum after washing clothes, or poor cleaning performance due to insufficient water flow or pressure. Over time, this can lead to bacterial growth and unsatisfactory washing results. Summary of the Invention

[0038] This invention discloses a clothing processing device to solve the problem that existing washing machines cannot clean the area between the inner drum and the outer drum, thus affecting the washing quality.

[0039] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0040] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a garment processing device provided in an embodiment of this application.

[0041] In one specific embodiment, the garment processing device provided in this application includes:

[0042] An outer tub 2 and an inner tub 1, with the inner tub 1 located inside the outer tub 2, and an interlayer provided between the outer tub 2 and the inner tub 1;

[0043] The nozzle device includes several nozzles, each nozzle being located within the interlayer, for spraying the inner tank 1 and / or the outer tank 2;

[0044] The ultrasonic device 4, located on the outer tub 2, is used to generate high-frequency vibrations in the water inside the clothing processing equipment.

[0045] The interlayer is an annular space between the inner wall of the outer tub 2 and the outer wall of the inner tub 1. It is an area where water, foam, and dirt easily accumulate during the washing process. The outer tub 2 and the inner tub 1 constitute the main structure of the equipment. The inner tub 1 is used to hold and wash clothes and can rotate. The spray head device consists of multiple spray heads, which can achieve multi-point and multi-angle full coverage rinsing to avoid blind spots. The spray heads can be fixedly installed on the inner wall of the outer tub 2 or on a specific bracket, with a stable position. The water outlet of the spray head can be set towards the outer wall of the inner tub 1 and the inner wall of the outer tub 2, spraying water directly onto the outer wall of the inner tub 1 and the inner wall of the outer tub 2 to wash away the dirt attached to them.

[0046] The ultrasonic device 4 generates ultrasonic waves and typically consists of an ultrasonic generator (power supply) and an ultrasonic transducer (vibrating head). The transducer is usually bonded or embedded in the bottom or side wall of the outer tank 2. The ultrasonic generator emits high-frequency electrical signals to drive the ultrasonic transducer to convert electrical energy into mechanical vibration. The ultrasonic device 4 is in direct contact with the outer tank 2, transferring ultrasonic energy to the internal water body through the tank. Specifically, the ultrasonic device 4 generates sound waves with frequencies higher than 20kHz, which propagate in the water and cause intense physical effects.

[0047] The specific working principle is as follows: When ultrasound propagates in water, it generates alternating rarefaction and compression waves. During the rarefaction phase, the water is locally "stretched," forming tiny vacuum bubbles (cavitation bubbles). During the compression phase, these bubbles undergo violent implosion (collapse) within an extremely short time (microseconds). The implosion of these bubbles generates extreme temperatures: instantaneous temperatures can reach thousands of degrees Celsius; extreme pressures: instantaneous pressures can reach hundreds or even thousands of atmospheres; and powerful shock waves and microjets: speeds can reach hundreds of meters per second. These extreme physical effects act on dirt, bacteria, viruses, etc., breaking down and peeling off large pieces of dirt; destroying the cell walls and internal structures of microorganisms, rendering them inactive; and the high-temperature, high-pressure environment accelerates the generation of free radicals, enhancing the water's oxidation capacity. In one embodiment, the nozzle's outlet faces the outer wall of the inner tank 1, allowing water to be sprayed directly onto the outer wall of the inner tank 1, washing away the dirt adhering to it.

[0048] The aforementioned device provides a wide-range water flow through a nozzle assembly to remove loose and attached dirt. The ultrasonic device 4 utilizes cavitation to penetrate deep into the microscopic level, removing dirt and biofilm from tiny crevices and effectively killing microorganisms. The cavitation effect of ultrasound has a broad-spectrum and highly effective killing ability against bacteria, viruses, fungi, and other microorganisms, and is less likely to induce drug resistance. Ultrasonic waves can penetrate into tiny crevices and pores that are difficult for water flow and brushes to reach, achieving thorough cleaning with a cleaning effect far exceeding that of simple water rinsing.

[0049] In one specific embodiment, each nozzle is evenly arranged circumferentially on the wall of the outer tub 2, and the water outlet faces the outer wall of the inner tub 1 to rinse the outer wall of the inner tub 1.

[0050] Multiple nozzles are installed on the inner wall of the outer tub 2, arranged at equal intervals around the circumference of the entire tub; for example, if there are 4 nozzles, they are located at 0°, 90°, 180°, and 270° respectively; if there are 6 nozzles, they are spaced one at every 60°, and so on. This uniform circumferential arrangement ensures that water flow can simultaneously or alternately scour the outer wall of the inner tub 1 from all directions, forming a complete rinsing ring and thoroughly eliminating cleaning dead zones. The uniform layout also ensures that the impact force of the water flow on the outer wall of the inner tub 1 is evenly distributed circumferentially, preventing over-scouring of some areas due to concentrated water flow while other areas are under-scored, thus guaranteeing consistent cleaning results.

[0051] Understandably, during the self-cleaning process, the inner tub 1 may rotate at a low speed or intermittently. Even if the inner tub 1 rotates, the circumferentially evenly distributed nozzles can ensure that at any time, there is a nozzle facing a certain part of the inner tub 1 to rinse, ensuring the continuity and comprehensiveness of rinsing. The evenly distributed nozzles can make more effective use of the limited water volume and pressure, avoid water flow interference or the formation of eddies, and improve rinsing efficiency.

[0052] The aforementioned nozzle device is responsible for large-scale physical rinsing, removing loose, large pieces of dirt and clearing obstacles for ultrasonic waves. The ultrasonic device 4 penetrates to the microscopic level, using cavitation to remove stubborn dirt and biofilm from tiny crevices and pores that are difficult for the nozzle's water flow to reach, and effectively kills microorganisms. The nozzle's rinsing loosens the dirt, making it easier for the ultrasonic shock waves and microjets to break it up and peel it off. The combination of these two methods results in a cleaning effect far exceeding that of using either device alone.

[0053] In one specific embodiment, in the axial direction of the outer barrel 2, some nozzles are evenly arranged circumferentially at the front and rear ends of the outer barrel 2.

[0054] And / or, some of the nozzles are arranged in a matrix in the middle of the outer barrel 2.

[0055] The outer drum 2 is located at the front end, near the door seal, and at the rear end, near the motor. A ring of nozzles is installed at each end, evenly distributed around its circumference, forming a ring around the drum wall. The nozzles between the front and rear ends are arranged in a matrix, forming a grid-like array on the wall surface of the central area. For example, 3 rows x 5 columns, or 4 rows x 6 columns, etc. This matrix arrangement allows for a large number of nozzles in the central area, creating a high-density rinsing matrix. The matrix arrangement ensures uniform rinsing (equal row and column spacing) and increases overall rinsing intensity by increasing the number of nozzles. The density of the matrix (number of rows and columns) can be flexibly adjusted according to water pressure, flow rate, and cleaning requirements.

[0056] The end section features a ring-shaped layout, focusing on areas where dirt tends to accumulate, forming a closed rinsing ring. The middle section uses a matrix layout to achieve large-area, high-density, uniform rinsing. Although the cavitation effect of ultrasound is powerful, its effectiveness is affected by the thickness and coverage area of ​​the dirt. Excessively thick dirt layers will absorb and attenuate ultrasonic energy. This three-dimensional nozzle layout can more thoroughly flush away large and deep dirt, creating channels for ultrasonic action, allowing it to more effectively target the tank walls and microorganisms, significantly improving overall cleaning efficiency.

[0057] In an optional embodiment, a control device is also included, which is connected to the nozzle device and the ultrasonic device 4 respectively, for controlling the nozzle device and the ultrasonic device 4 to start simultaneously.

[0058] The control device is typically equipped with a microprocessor, upgrading the self-cleaning function from a simple mechanical action to a programmable and coordinated intelligent process; providing the hardware foundation for precise control of the timing and status of multiple actuators (nozzle head, ultrasonic waves). The control device establishes an electrical or signal connection with the drive components (such as solenoid valves, water pump motors, ultrasonic generators) of the nozzle device and ultrasonic device 4 via wires or signal lines; enabling the control device to issue commands and monitor the status of these two devices.

[0059] Specifically, the user selects or the device automatically enters the "self-cleaning program"; the control device receives the start signal; the control device sends start commands to the nozzle device (possibly by controlling the water pump and solenoid valve) and the ultrasonic device 4 (by controlling the ultrasonic generator); the nozzle starts spraying water, and the ultrasonic transducer starts vibrating, both starting to work at the same time or in a very short time; the high-pressure water flow and the ultrasonic cavitation effect work together to remove water and dirt from the interlayer.

[0060] High-pressure water flow disperses and peels away large pieces of dirt; it generates disturbance and bubbles in the water, which act as "seeds" for ultrasonic cavitation, making it easier to form cavitation bubbles in the sound field; it carries away dirt particles broken up by ultrasound, preventing them from re-adhering. The strong shock waves and micro-jets of ultrasound significantly enhance the scouring force of the water flow, allowing it to penetrate crevices more effectively; it can break down stubborn biofilms and scale that are difficult for water flow to remove; and it kills bacteria and viruses at the microscopic level, compensating for the shortcomings of simple physical rinsing in sterilization. A unified control device ensures that the operating parameters (such as start time and duration) of each self-cleaning program remain consistent, without fluctuations due to human operation or random factors; reducing the possibility of program errors.

[0061] In one embodiment, a drainage device 5 is also included, located at the bottom of the outer barrel 2 and communicating with the interlayer. The drainage device 5 is connected to the control device and is used to drain the water inside the outer barrel 2.

[0062] The drainage device 5 includes components such as a drainage pump, drainage valve, drainage pipe, and filter. It is located at the bottom of the outer tub 2. Dirt and water will naturally flow to the lowest point under the action of gravity, making it easy to be completely discharged. The water inlet or outlet of the drainage device 5 is directly connected to the interlayer space between the inner tub 1 and the outer tub 2, providing a dedicated and efficient discharge channel for the sewage in the interlayer (containing the dirt, debris, and microbial remains broken by ultrasonic waves).

[0063] Example 2

[0064] like Figure 2-7 As shown, Figure 2 This is a schematic diagram of the structure of an inner barrel provided in an embodiment of this application; Figure 3 for Figure 2 A magnified view of the structure at point A in the middle; Figure 4 This is a schematic diagram of the inner barrel structure provided in another embodiment of this application; Figure 5 for Figure 4 A magnified schematic diagram of the structure at point B in the middle; Figure 6 This is a schematic diagram of the structure of the flow guide provided in an embodiment of this application; Figure 7 for Figure 6 A magnified schematic diagram of the structure at point C.

[0065] This embodiment is an expanded description based on Embodiment 1.

[0066] In one specific embodiment, the clothing processing equipment provided in this application includes an inner tub 1;

[0067] Several flow guides 3 are provided on the circumferential outer wall of the inner barrel 1. Each flow guide 3 has a hollow closed cavity. In the width direction of the flow guide 3, one end of each flow guide 3 is provided with a water inlet 31 and the other end is provided with a water outlet 32. The water inlet 31 and the water outlet 32 ​​are respectively connected to the hollow closed cavity.

[0068] The inner drum is a rotating tub used in clothing handling equipment to hold and wash clothes. The guide section 3 is fixed or integrally formed on the outer surface of the inner drum 1, and is arranged at certain intervals along the circumference of the inner drum 1 to ensure that the water flow can cover the drum wall. The guide section 3 can be connected to the inner drum 1 by injection molding, welding or bolts. Its shape can be long strip, arc or other streamlined shape to optimize water flow. The interior of each guide section 3 is a closed, hollow pipe or channel. The inlet 31 and the outlet 32 ​​are located at both ends of the guide section 3, so that the water flow must pass through the entire hollow cavity to flow out, maximizing the use of the length of the guide section 3. The water flow path is: inlet 31, hollow closed cavity to outlet 32, ensuring that the water flow can smoothly flow into, through and out of the guide section 3.

[0069] The specific working process is as follows: the self-cleaning program is started and the water pump starts to work; the pressurized water flow is guided to the inlet 31 of each guide section 3; the water flow enters the hollow closed cavity of the guide section 3 and flows inside; the water flow is sprayed out from the outlet 32 ​​of the guide section 3; the sprayed water flow directly impacts the outer wall of the inner barrel 1 (i.e. the barrel surface to which the guide section 3 is attached) and the interlayer space to achieve rinsing.

[0070] Compared with the prior art, the garment processing device provided in this application has the following technical advantages:

[0071] Several guide sections 3 are provided on the circumferential outer wall of the inner cylinder. The water inlet 31 and the water outlet 32 ​​are located at both ends of the guide section 3, so that the water flow must pass through the entire hollow cavity to flow out. The launch point of the cleaning water flow is directly located on the surface to be cleaned. This allows the water flow to directly flush the dirt accumulation area with the shortest distance and the largest angle, resulting in extremely high cleaning efficiency. Since the water outlet 32 ​​is located on the outer wall of the inner cylinder 1, the water flow can generate the strongest shearing force, effectively removing stubborn dirt. This avoids the rinsing dead angles or power reduction caused by the long distance and poor angle of traditional nozzles.

[0072] In one embodiment, the inner tub 1 is arranged horizontally; the guide portion 3 extends axially along the inner tub 1; the axial direction is along the central rotation axis of the inner tub 1, that is, the length direction from the front end (door side) to the rear end (motor side) of the tub. Since the guide portion 3 extends axially, the water outlet 32 ​​on it can be arranged along the entire length of the tub; when water is sprayed from the water outlet 32, it can simultaneously wash the entire outer wall area of ​​the inner tub 1 from the front end to the rear end of the tub and the inner wall area of ​​the outer tub 2; this ensures that there are no blind spots in the axial direction, achieving full longitudinal coverage.

[0073] The axially extending hollow closed cavity provides a long and straight flow channel for water, reducing resistance and pressure loss inside the guide section 3. Water can flow smoothly from the inlet 31 to the outlet, ensuring stable flow and pressure at the outlet 32. The specific working process is as follows: When the self-cleaning program is activated, the inner tub 1 rotates around its own axis. When the guide section 3 passes the bottom water in the outer tub 2, the water flows in through the guide section 3 from the inlet 31 and flows out from the outlet 32 ​​under the centrifugal force of the rotating inner tub, rinsing the outer wall of the inner tub 1 and the inner wall of the outer tub 2. It does not require an additional nozzle device; the centrifugal force of the rotating inner tub 1 drives the water to be sprayed through the guide section 3, thus achieving the cleaning of the interlayer area between the outer wall of the inner tub 1 and the inner wall of the outer tub 2.

[0074] In one optional embodiment, the centerline of the inlet 31 is collinear with the tangent of the inner tub 1; the direction of the inlet 31 is parallel to the surface of the outer wall of the inner tub 1 and is circumferential; ensuring that the water flow enters the hollow closed cavity of the guide section 3 tangentially rather than radially or axially. When the water flow enters the guide section 3 tangentially, it flows along the inner wall of the guide section 3 instead of directly impacting the opposite wall; the water inlet method has minimal resistance, effectively reducing turbulence, eddies, and energy loss at the inlet, ensuring that the water flow enters the hollow cavity smoothly and efficiently. Due to the reduced inlet resistance, more pumping energy can be converted into the kinetic energy and pressure of the water flow. This means that the water flow ejected from the outlet 32 ​​will have higher speed and stronger impact force, thereby significantly improving the flushing effect.

[0075] Radial or oblique water inlet can easily create a local low-pressure area at the inlet, causing water vaporization and the formation of bubbles (cavitation). When the bubbles burst, they will generate noise and vibration, and may damage the inner wall of the guide section 3 (cavitation). Tangential water inlet can effectively avoid this situation, making the system operate more quietly and reliably.

[0076] In one embodiment, the guide section 3 is a rectangular guide section 3, with the inlet 31 and outlet 32 ​​located on the side walls on both sides of the rectangular guide section 3 in the width direction; the inlet 31 and outlet 32 ​​are respectively opened on two opposite sides of the rectangular guide section 3, and are opposite to each other in the width direction. The water flows in from the inlet 31 on one side wall, must cross the entire hollow closed cavity, and flow out from the outlet 32 ​​on the other side wall; this "lateral flow" path can effectively agitate the water flow inside the guide section 3, reduce dead water areas, and ensure that the water in the entire hollow cavity can be renewed and utilized; for any small air bubbles or impurities that may exist, the lateral flow also helps to carry them out and prevent them from accumulating in the cavity.

[0077] Furthermore, there are several water outlet holes 32, and each water outlet hole 32 is evenly arranged on one side wall of the rectangular guide section 3 in the width direction.

[0078] Several water outlets 32 are provided to achieve a complex water flow distribution and stronger cleaning ability. All water outlets 32 are located on the same sidewall of the rectangular guide section 3, and are arranged at equal intervals along the length of this sidewall. If the guide section 3 is 60cm long and has 6 water outlets 32, they are spaced 10cm apart and evenly distributed from front to back. This creates multiple flushing points along the entire length of the guide section 3, ensuring water coverage from the front to the back of the container and completely eliminating linear blind spots. Simultaneous spraying from multiple water outlets 32 improves overall cleaning efficiency. After entering through the inlet 31, the water flows axially within the hollow cavity of the guide section 3. The even distribution of multiple water outlets 32 allows for more rational water flow allocation, preventing all water from rushing to the nearest outlet 32. A well-designed system ensures relatively balanced flow and pressure at each water outlet 32.

[0079] Multiple water outlets 32 are located on the same side wall, which means that after the water flows through, it will spray out from multiple points on the side wall at the same time. This design enables the horizontal flow pattern to serve multiple water outlets at the same time, improving the utilization efficiency of the hollow cavity. A row of evenly distributed water outlets 32 forms a continuous flushing band on the outer wall of the inner barrel 1, which effectively removes dirt distributed in the depth direction of the barrel.

[0080] In one optional embodiment, the inlet 31 is located in the middle of the length direction of the guide section 3. The length direction of the guide section 3 is consistent with the axial direction of the inner barrel 1. The guide section 3 is located in the central region along the length direction. When the inlet 31 is located in the middle of the length direction of the guide section 3, the water flows into the hollow closed cavity and flows in two directions (front end and rear end) simultaneously. If the outlet holes 32 are located at both ends of the guide section 3 or distributed in the regions at both ends, this "center inlet, two-end outlet" mode can ensure that the flow path length of the water from the center to both ends is equal. This symmetrical flow channel design makes the resistance and pressure loss of the water flow when it reaches the two outlet holes 32 (or the group of outlet holes 32 at both ends) basically the same, thereby ensuring that the flow rate and pressure of the outlet holes 32 at both ends are highly balanced; avoiding the uneven phenomenon of "more water at one end and less water at the other end".

[0081] The design improves overall rinsing uniformity, with pressure equalization directly translating into uniform rinsing force. Both the front and rear ends of the inner tub's outer wall receive the same water flow intensity, resulting in consistent cleaning. For the elongated guide section 3, this design effectively prevents pressure attenuation at the end due to an excessively long water flow path. Because the water flow branches from the center to both ends, the flow path in each direction is only half the total length of the guide section 3. Compared to a design where water enters from one end and exits from the other, the single-pass flow distance is halved, significantly reducing water flow resistance. This allows for higher end flow velocity and impact force. The inlet 31 is located in the middle, typically closer to the rotational axis of the inner tub 1. This makes connecting the inlet pipe or distributor easier, allowing the pipe to be arranged along the axis and simplifying the internal structure.

[0082] In another embodiment, the directions of each water outlet 32 ​​are different, thereby enabling spraying to various parts of the interlayer area formed by the outer tub 2 and the inner tub 1, expanding the rinsing direction and rinsing area, achieving more comprehensive rinsing, and improving the rinsing effect.
