Description

Technical Field

[0001] The present application relates to the technical field of laundry treatment equipment, and more particularly to a dosing device for laundry treatment equipment and a laundry treatment equipment. Background Art

[0002] In the field of washing machine technology, the traditional atomized washing technology sprays the detergent onto the surface of the clothes after atomizing it with high-pressure water flow to enhance the washing effect and reduce water consumption. However, this technology faces a significant technical problem in practical applications: due to the huge pressure generated during the high-pressure atomization of the water flow, existing washing machine designs often need to be provided with a dedicated pressure relief port to balance the system pressure and prevent equipment damage (such as causing the water box to rupture, leak, or performance degradation, etc.). However, this design compromise directly results in some of the atomized laundry detergent flowing back through the pressure relief port under high pressure to the space between the detergent box and the inner and outer tubs, rather than directly acting on the clothes. This phenomenon not only weakens the penetration and peeling ability of the atomized bubbles on the stains of the clothes, greatly reducing the advantages of the atomized washing technology, but also causes waste of the detergent, reduces the utilization rate of the detergent, increases the washing cost of the user.

[0037] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0038] Reference will be made below to Figures 1 - 3 Describe a dosing device 1000 for a laundry treatment apparatus and a laundry treatment apparatus according to embodiments of the present application.

[0039] As Figure 1 shown, a dosing device 1000 for a laundry treatment apparatus according to a first aspect embodiment of the present application, the dosing device 1000 for a laundry treatment apparatus includes: a water box 1 and a flow limiting device 2.

[0040] Among them, the water box 1 is provided with a water inlet cavity; a flow limiting channel is formed in the flow limiting device 2, the flow limiting channel is communicated with the water inlet cavity, and the flow limiting device 2 is adapted to limit the fluid flow rate in the flow limiting channel.

[0041] Specifically, a water inlet cavity is formed in the water box 1. The water inlet cavity can be used for the injection, storage and discharge of fluid. The water inlet cavity can have a water inlet and a water outlet. The water outlet can be connected to the spraying system of the laundry treatment device to spray a washing medium, such as water and a detergent solution, into the laundry treatment cavity. The water inlet of the water inlet cavity can be connected to the flow limiting device 2. The flow limiting device 2 can be arranged at the water inlet or on the pipeline connected thereto. It can be understood that the flow limiting device 2 is located upstream of the water inlet. A flow limiting channel is formed in the flow limiting device 2, and the flow limiting channel is communicated with the water inlet cavity of the water box 1. By limiting the fluid flow rate in the flow limiting channel, that is, the volume of fluid passing through the flow limiting channel per unit time, the fluid flow velocity on the inlet side of the flow limiting channel can be increased, and accordingly, the dynamic pressure of the fluid on the inlet side is increased. At the same time, due to the increase in dynamic pressure, the pressure energy of the fluid (mainly manifested as static pressure) will be correspondingly reduced to maintain the conservation of the total energy (dynamic pressure + static pressure + potential pressure, and the potential pressure can be ignored in a horizontal pipeline). Therefore, due to the increase in flow velocity, the static pressure of the fluid near the outlet of the flow limiting channel will be reduced, and further, the pressure of the fluid entering the water inlet cavity can be reduced, which can avoid damaging the equipment due to the high pressure of the fluid, and further, an additional pressure relief port can be eliminated.

[0042] According to the dosing device 1000 for a laundry treatment device of the present application, by providing a flow limiting device 2 to limit the fluid flow rate and utilizing the conversion of fluid energy from pressure energy to kinetic energy, the pressure of the fluid entering the water inlet cavity can be reduced to protect the equipment from high-pressure damage, and an additional pressure relief port can be eliminated. In this way, it can be avoided that the washing medium flows back from the pressure relief port to the space between the detergent box and the inner and outer drums of the laundry treatment device, and it can be realized that the washing medium can directly act on the clothes entirely, thereby improving the atomized bubble effect of the detergent, increasing the utilization rate of the detergent, enhancing the laundry effect and efficiency, and saving the laundry cost.

[0043] As Figure 3 shown, according to some embodiments of the present application, the flow limiting device 2 includes: a flow limiting portion 21, the flow limiting portion 21 is arranged in the flow limiting channel and is adapted to block at least part of the fluid, and a plurality of flow limiting holes 21a are formed on the flow limiting portion 21.

[0044] Specifically, a flow-limiting portion 21 may be provided in the flow-limiting channel. The flow-limiting portion 21 may span the entire cross-section of the flow-limiting channel or be designed to cover a part of the cross-section of the flow-limiting channel as required. Exemplarily, the flow-limiting portion 21 may be configured as a flow-limiting plate or the like. The flow-limiting portion 21 can block at least part of the fluid in the flow-limiting channel. It should be noted that this blockage does not completely prevent the fluid from flowing, but blocks at least part of the fluid from directly passing through the flow-limiting channel. At least part of the fluid needs to bypass the blocking part on the flow-limiting portion 21 and then pass through the flow-limiting hole 21a on the flow-limiting portion 21 to pass through the flow-limiting channel, thereby restricting the fluid flow rate and changing the fluid velocity. Specifically, when the fluid passes through the flow-limiting portion 21, due to the reduction of the flow area, the flow velocity of the fluid will increase on the water inlet side of the flow-limiting portion 21, so that the dynamic pressure of the fluid on the inlet side increases, and the static pressure of the fluid near the outlet of the flow-limiting channel can be reduced, and the fluid pressure on the outlet side of the flow-limiting channel can be reduced.

[0045] In addition, in some specific embodiments of the present application, the flow-limiting hole 21a may be configured as a hole with a regular shape such as a circular hole, a rectangular hole or an oval hole, etc., so as to facilitate production and manufacturing and improve the uniformity of flow distribution; in some other specific embodiments of the present application, the flow-limiting hole 21a may also be configured as a special-shaped hole to provide more complex flow control characteristics or meet specific process requirements.

[0046] As Figure 2 shown, according to some embodiments of the present application, the flow-limiting device 2 further includes: a flow-limiting structure body 22, a first pipe body 23 and a second pipe body 24.

[0047] Among them, a first channel section is formed in the flow-limiting structure body 22, and the flow-limiting portion 21 is arranged in the first channel section; the first pipe body 23 and the second pipe body 24 are respectively arranged on both sides of the flow-limiting structure body 22, and respectively form a second channel section and a third channel section communicating with the first channel section; the first pipe body 23 is adapted to communicate with an external water source, and the second pipe body 24 is adapted to communicate with the water inlet cavity.

[0048] Specifically, the first pipe body 23, the current-limiting structure body 22, and the second pipe body 24 are connected in sequence. The second channel section in the first pipe body 23, the first channel section in the current-limiting structure body 22, and the third channel section in the second pipe body 24 are connected in sequence. Among them, the first pipe body 23 is adapted to be connected to an external water source, and the second pipe body 24 is adapted to be connected to the water inlet cavity of the water box 1. Thus, the external water source can flow into the water inlet cavity after flowing through the second channel section, the first channel section, and the third channel section in sequence. Among them, a current-limiting part 21 is arranged in the first channel section. Therefore, when the fluid flows through the second channel section, the current-limiting part 21 can block the fluid in the first channel section and adjust the flow rate of the fluid through the current-limiting holes 21a on it. The pressure of the fluid after being adjusted by the current-limiting part 21 decreases and can enter the water inlet cavity through the third channel section. By supplying the fluid with adjusted flow rate and pressure, the atomized bubble effect of the washing medium can be improved, and the utilization rate of the detergent and the washing effect can be enhanced. In addition, by integrating the current-limiting part 21 into the current-limiting structure body 22 and connecting it with the first pipe body 23 and the second pipe body 24, the entire current-limiting device 2 is also made structurally compact, which helps to improve the convenience of installation and maintenance.

[0049] As Figure 2 and Figure 3 shown, according to some embodiments of the present application, the cross-sectional area of the second channel section is configured as S1, the cross-sectional area of the third channel section is configured as S2, and the sum of the cross-sectional areas of the plurality of current-limiting holes 21a is configured as S3, and it satisfies: S1 > S3, S2 > S3.

[0050] Specifically, since the current-limiting part 21 is arranged in the first channel section, therefore, the second channel section is located upstream of the plurality of current-limiting holes 21a, and the cross-sectional area of the second channel section is set to be larger than the sum of the cross-sectional areas of the plurality of current-limiting holes 21a. In this way, in the second channel section, the flow space of the fluid is relatively large, which helps the fluid to flow smoothly and accumulate a certain pressure before reaching the current-limiting holes 21a; the third channel section is located downstream of the plurality of current-limiting holes 21a, and the cross-sectional area of the third channel section is also set to be larger than the sum of the cross-sectional areas of the plurality of current-limiting holes 21a. In this way, after the fluid passes through the current-limiting holes 21a and enters the third channel section, although it has undergone current-limiting treatment, in the third channel section, the fluid still has enough space to continue flowing, which helps to improve the flow smoothness of the fluid flowing out of the current-limiting device 2.

[0051] By setting the size relationship among the cross-sectional area S1 of the second channel section, the cross-sectional area S2 of the third channel section, and the sum S3 of the cross-sectional areas of the plurality of current-limiting holes 21a within the above range, the cross-sectional areas of the second channel section, the third channel section, and the current-limiting holes 21a are made reasonable, which can ensure a good current-limiting effect of the current-limiting device 2 on the fluid while improving the flow smoothness of the fluid flowing out of the current-limiting device 2, and is beneficial to improving the washing efficiency.

[0052] As Figure 2 and Figure 3 shown, according to some embodiments of the present application, the cross-sectional area S1 of the second channel section is greater than the cross-sectional area S2 of the third channel section.

[0053] Specifically, by setting the cross-sectional area of the second channel section to be relatively large, a relatively large buffer space can be provided before the fluid enters the flow-limiting hole 21a, enabling the fluid to flow more smoothly, reducing turbulence or impact caused by too fast a flow rate or too large a flow volume, protecting the flow-limiting device 2 from impact damage, and facilitating improving the adaptability of the flow-limiting device 2 to an external water source with a conventional flow rate (such as 4 L / min or 8 L / min, etc.). Moreover, the relatively large cross-sectional area also helps store more fluid when needed for precise control in subsequent processes; by setting the cross-sectional area of the third channel section to be relatively small, when the fluid passes through the flow-limiting hole 21a and enters the third channel section, the flow rate and flow volume limiting effect of the fluid can be ensured, guaranteeing the flow rate and flow volume of the fluid entering the water inlet cavity from the third channel section, etc., thereby improving the control accuracy of various parameters (such as detergent solution concentration, water temperature, etc.) in the subsequent clothing treatment process. Therefore, by reasonably configuring the cross-sectional areas of the second channel section and the third channel section, the working stability of the entire dosing device 1000 for a clothing treatment device under different working conditions can be improved. The second channel section with a relatively large cross-sectional area can reduce the impact of fluid fluctuations or external disturbances on the system stability, while the third channel section with a relatively small cross-sectional area can ensure that the fluid is fully controlled and regulated before entering the clothing treatment area.

[0054] As Figure 1 shown, according to some embodiments of the present application, the dosing device 1000 for a clothing treatment device further includes: a water inlet valve 3 and a first conduit 4.

[0055] Wherein, one end of the first conduit 4 is sleeved on the outer periphery of the first pipe body 23, and the other end is connected to the water inlet valve 3.

[0056] Specifically, the first conduit 4 has a certain length, and the two ends of the first conduit 4 in the extending direction are respectively connected to the first pipe body 23 and the water inlet valve 3 to conduct the first pipe body 23 and the water inlet valve 3. The water inlet valve 3 can precisely control the external water source entering the first conduit 4 to flexibly adjust the water volume entering the first pipe body 23 through the first conduit 4, thereby providing an appropriate amount of water with an appropriate temperature according to different stages and requirements of clothing treatment, and further improving the flexibility of water flow control, providing a more efficient, convenient, and comfortable clothing treatment experience for users.

[0057] It should be noted that the above-mentioned assembly form in which one end of the first conduit 4 is sleeved on the outer periphery of the first pipe body 23 is conducive to ensuring good connection stability between the first conduit 4 and the first pipe body 23, and can make the connection between the first conduit 4 and the first pipe body 23 convenient and intuitive, which helps to improve the assembly efficiency and maintenance convenience of the first conduit 4 and the first pipe body 23.

[0058] As Figure 1 and Figure 2 shown, according to some embodiments of the present application, a first limiting portion is formed on the inner peripheral surface of the first conduit 4, and a second limiting portion 232 is formed on the outer peripheral surface of the first pipe body 23. The second limiting portion 232 is adapted to cooperate with the first limiting portion to limit the relative movement of the first pipe body 23 with respect to the first conduit 4.

[0059] Specifically, a first limiting portion and a second limiting portion 232 are respectively formed on the inner peripheral surface of the first conduit 4 and the outer peripheral surface of the first pipe body 23. The second limiting portion 232 is adapted to cooperate with the first limiting portion. The first limiting portion may be a structure such as a protrusion, a groove or a clamping groove formed on the inner peripheral surface of the first conduit 4, and the second limiting portion 232 may correspondingly be a structure such as a groove, a protrusion or a buckle matching the first limiting portion. Through the limiting cooperation of the first limiting portion and the second limiting portion 232, on the one hand, the assembly positioning accuracy and accuracy of the first pipe body 23 and the first conduit 4 can be improved, and the stability and accuracy of the position of the first pipe body 23 relative to the first conduit 4 can be ensured. In this way, accidental movement or deviation of the first pipe body 23 during operation can be prevented, so that the accuracy and stability of water flow delivery can be effectively guaranteed; on the other hand, through the limiting cooperation of the first limiting portion and the second limiting portion 232, the connection strength between the first conduit 4 and the first pipe body 23 can also be enhanced, and loosening or damage of the connection caused by vibration or external force can be avoided.

[0060] As Figure 2 shown, according to some embodiments of the present application, the second limiting portion 232 is configured as a plurality of sequentially arranged in the extending direction of the first pipe body 23, and each second limiting portion 232 is configured as a limiting protrusion extending radially away from the first pipe body 23, and the diameter of each limiting protrusion gradually increases in the direction close to the flow limiting portion 21.

[0061] Specifically, the second limiting portion 232 may be configured as a plurality, and the first limiting portion is configured as a plurality corresponding to the second limiting portion 232 one by one. By increasing the number of the second limiting portion 232 and the first limiting portion, the number of limiting points and the connection area between the first pipe body 23 and the first conduit 4 can be increased, which helps to improve the stress dispersion uniformity of the first pipe body 23 and the first conduit 4 when subjected to external forces, and further enhance the connection stability between the two, improve the working reliability of the two and extend the service life.

[0062] Moreover, each second limiting portion 232 is configured as a limiting protrusion extending radially away from the first pipe body 23. The diameter of each limiting protrusion gradually increases in the direction close to the flow limiting portion 21. Then, a plurality of first limiting portions on the first conduit 4 are configured as limiting grooves for cooperating with the plurality of limiting protrusions. The limiting protrusions are adapted to extend into the corresponding limiting grooves to achieve limiting cooperation. Among them, the diameter of the limiting protrusion gradually increases in the direction close to the flow limiting portion 21, so that the limiting protrusion and the limiting groove can abut in the extending direction of the first pipe body 23, which plays a good role in restricting the movement of the first pipe body 23 and the first conduit 4 in the extending direction, and can further improve the connection stability and reliability of the first pipe body 23 and the first conduit 4.

[0063] As Figure 1 shown, according to some embodiments of the present application, the dosing device 1000 for a laundry treatment device further includes: a second conduit 5. One end of the second conduit 5 is sleeved on the outer periphery of the second pipe body 24, and the other end is connected to the water inlet chamber.

[0064] Specifically, the second conduit 5 has a certain length. The two ends of the second conduit 5 in the extending direction are respectively connected to the second pipe body 24 and the water inlet chamber to conduct the second pipe body 24 and the water inlet chamber. When the fluid flows through the first conduit 4 and the first pipe body 23 in sequence from the water inlet valve 3, the flow limiting adjustment can be realized through the flow limiting portion 21 in the flow limiting structure body 22. After the flow limiting adjustment, the fluid can flow into the water inlet chamber after flowing through the second pipe body 24 and the second conduit 5 in sequence for subsequent laundry treatment. By providing the second conduit 5, a good guiding effect can be exerted on the fluid, so that the fluid can quickly and accurately enter the water inlet chamber, thereby improving the efficiency and quality of the entire laundry treatment process. At the same time, the convenience of separate maintenance and replacement of the second pipe body 24 and the water box 1 can also be improved.

[0065] Similarly, adopting the assembly form in which one end of the second conduit 5 is sleeved on the outer periphery of the second pipe body 24 is beneficial to ensuring good connection stability between the second conduit 5 and the second pipe body 24, and can make the connection between the second conduit 5 and the second pipe body 24 convenient and intuitive, which helps to improve the assembly efficiency and maintenance convenience of the second conduit 5 and the second pipe body 24.

[0066] As Figure 1 and Figure 2 shown, according to some embodiments of the present application, a first clamping portion is formed on the inner peripheral surface of the second conduit 5, and a second clamping portion is formed on the outer periphery of the second pipe body 24. The second clamping portion is adapted to be clamped and cooperate with the first clamping portion.

[0067] Specifically, a first engaging portion and a second engaging portion are respectively formed on the inner peripheral surface of the second conduit 5 and the outer peripheral surface of the second tube body 24. The first engaging portion is adapted to be engaged and cooperate with the second engaging portion. The specific shapes and dimensions of the first engaging portion and the second engaging portion can be designed according to actual requirements. Exemplarily, the first engaging portion and the second engaging portion can be a protrusion and a groove, a tooth groove, or other structures that can engage with each other. By providing the first engaging portion and the second engaging portion, the connection stability between the second tube body 24 and the second conduit 5 can be improved, and the working reliability of the second conduit 5 and the second tube body 24 can be enhanced. At the same time, the use of snap-fit also facilitates the installation and disassembly between the second conduit 5 and the second tube body 24. For example, during installation, the user only needs to sleeved the second conduit 5 on the second tube body 24 and gently rotate or press it to ensure that the first engaging portion and the second engaging portion engage with each other. When maintenance or component replacement is required, they can also be easily separated.

[0068] As Figure 3 shown, according to some embodiments of the present application, the sum of the cross-sectional areas of the plurality of flow-limiting holes 21a is less than or equal to 2.5 mm 2 .

[0069] Specifically, when the sum of the cross-sectional areas of the plurality of flow-limiting holes 21a is too large, for example, the sum of the cross-sectional areas of the plurality of flow-limiting holes 21a is 3 mm 2 or 3.5 mm 2 etc., it will cause the flow-limiting force of the flow-limiting portion 21 to be too small, resulting in poor flow-limiting and pressure-reducing effects, and affecting the safety of the device and the utilization rate of the detergent. The sum of the cross-sectional areas of the plurality of flow-limiting holes 21a of the present application is set to be less than or equal to 2.5 mm 2 range, so that the flow-limiting holes 21a have a suitable flow area. In this way, the flow-limiting force of the flow-limiting device 2 can be ensured, the requirements for flow-limiting and pressure-reducing of the fluid in the water inlet chamber can be met, so as to realize that an additional pressure relief port can be cancelled, so that the washing medium can all directly act on the clothes, improve the atomized bubble effect of the detergent, and improve the utilization rate of the detergent.

[0070] It should be noted that the minimum value of the sum of the cross-sectional areas of the plurality of flow-limiting holes 21a can be designed accordingly according to different requirements of different clothes treatment devices. However, the sum of the cross-sectional areas of the plurality of flow-limiting holes 21a should not be too small, especially when the cross-sectional area of a single flow-limiting hole 21a is too small, it may occur that the flow-limiting hole 21a is blocked due to impurity accumulation or increased fluid viscosity during long-term use, reducing the washing efficiency and effect.

[0071] In addition, in some specific embodiments of the present application, the number of the flow-limiting holes 21a is configured to be five, and the flow-through areas of each of the flow-limiting holes 21a are the same. Four of the flow-limiting holes 21a are arranged at intervals in the circumferential direction, and another flow-limiting hole 21a is arranged at the center position of the flow-limiting portion 21 and is located inside the four flow-limiting holes 21a. In this way, when the fluid passes through these flow-limiting holes 21a, each flow-limiting hole 21a bears the same flow rate, and the fluid is evenly distributed in the circumferential and radial directions, which can improve the uniformity and stability of the overall flow rate.

[0072] As Figures 1 - 3 shown, according to some embodiments of the present application, the flow-limiting portion 21 is configured as a flange plate, and the outer edge of the flange plate protrudes from the first pipe body 23 and the second pipe body 24 and is respectively in axial contact with the first conduit 4 and the second conduit 5.

[0076] Specifically, one end of the first pipe body 23 facing away from the second pipe body 24 may be provided with a first guiding portion 231. A first guiding surface is provided on the outer periphery of the first guiding portion 231, and the first guiding surface is inclined towards the axis in a direction away from the second pipe body 24. The first guiding surface can play a good role in positioning and guiding the assembly of the first pipe body 23 and the first conduit 4, which is conducive to improving the assembly accuracy and efficiency; one end of the second pipe body 24 facing away from the first pipe body 23 may be provided with a second guiding portion 241. A second guiding surface is provided on the outer periphery of the second guiding portion 241, and the second guiding surface is inclined towards the axis in a direction away from the first pipe body 23. Similarly, the second guiding surface can play a good role in positioning and guiding the assembly of the second pipe body 24 and the second conduit 5, which is conducive to improving the assembly accuracy and efficiency.

[0077] In addition, both the first guiding surface and the second guiding surface are inclined, and the inclination directions are away from each other and towards the axis, which enables the first guiding portion 231 and the second guiding portion 241 to also have a limiting effect, can enhance the anti-disconnection performance between the first pipe body 23 and the first conduit 4, and between the second pipe body 24 and the second conduit 5, and further improve the working reliability of the flow limiting device 2, the first pipe body 23, and the second pipe body 24.
