Detailed Embodiments

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

It should be understood that the orientation descriptions "above", "below", "outside", and "inside" are all in the orientation in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which may or may not be the left and right directions in the normal use state.

[0041] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, article or device including the element. "Plurality" means greater than or equal to two.

[0042] The embodiment of the present application provides a clothing treatment device. Please refer to Figure 1 and Figure 2 , which includes a clothing treatment cylinder 10, a door seal 20, a door body assembly 30 and a filling member 40.

[0043] The clothing treatment cylinder 10 has a clothing accommodation cavity 10a, and the front end of the clothing accommodation cavity cylinder 10a has an opening. The clothing is processed in the clothing accommodation cavity 10a.

[0044] Please refer to Figure 1 and Figure 2 , the door seal 20 is arranged on the front side of the clothing treatment cylinder 10, and the door seal 20 has a clothing feeding port 20a communicating with the clothing accommodation cavity 10a. The user can put the clothing into the clothing accommodation cavity 10a from the clothing feeding port 20a. It should be noted that the front side of the clothing treatment cylinder 10 refers to the side facing the user.

[0045] Exemplarily, the clothing treatment device further includes a housing, and the clothing treatment cylinder 10 is arranged in the housing. The housing has an installation opening, and the door seal 20 is arranged at the installation opening. The door body assembly 30 is arranged on the housing, and the housing provides an installation position and a force support for the door body assembly 30.

[0046] Please refer toFigure 1 and Figure 2 , the door body assembly 30 is used to open or close the clothing inlet 20a. A part of the door body assembly 30 protrudes inward to define a protruding portion 30a. The protruding portion 30a extends into the clothing inlet 20a, and there is a spaced area 20b between the protruding portion 30a and the bottom wall of the clothing inlet 20a. It should be noted that the door body assembly 30 also realizes the function of opening or closing the opening while opening or closing the clothing inlet 20a. The protruding portion 30a extends into the clothing inlet 20a, which can push the clothes towards the clothing receiving cavity 10a to prevent the clothes from gathering in the clothing inlet 20a and resulting in the clothes not being cleaned. In addition, it is also helpful to inject water from above the protruding portion 30a to realize the flushing of the protruding portion 30a.

[0047] Please refer to Figures 1 to 4 , the filling member 40 has an expanded state and a contracted state and can switch between the expanded state and the contracted state. In the expanded state, the filling member 40 bulges to fill at least part of the spaced area 20b; in the contracted state, the filling member 40 contracts to relieve the filling of the spaced area 20b.

[0048] Specifically, when entering the washing program, the filling member 40 can switch from the contracted state to the expanded state to block the clothes from extending into the spaced area 20b between the bottom wall of the clothing inlet 20a and the protruding portion 30a. When the washing program ends and enters the dehydration program, the filling member 40 can switch from the expanded state to the contracted state. On the one hand, it is convenient for the user to put in or take out clothes through the clothing inlet 20a after the dehydration program ends; on the other hand, it reduces the interference of the filling member 40 on the rapid rotation of the clothing treatment cylinder 10, and also reduces the probability of the clothing treatment cylinder 10 damaging the filling member 40 during the rapid rotation, reducing the failure rate.

[0049] It can be understood that the clothes in the clothing receiving cavity 10a are affected by gravity. When the centrifugal force applied to the clothes by the clothing treatment cylinder 10 is high enough to overcome the gravity, the clothes will cling to the inner wall of the clothing treatment cylinder 10 under the action of the centrifugal force and cannot enter the spaced area 20b. When the centrifugal force applied to the clothes by the rotation of the clothing treatment cylinder 10 is not enough to overcome the gravity, the clothes will concentrate at the bottom of the clothing receiving cavity 10a. The filling member 40 in the expanded state can block the clothes at the bottom of the clothing receiving cavity 10a from entering the spaced area 20b.

[0050] In the related art, a clothes blocking rib is provided on the bottom wall of the clothes inlet of the door seal to prevent clothes from falling into the gap area between the clothes treatment cylinder and the glass door of the door body. However, during the process of the user taking out or putting clothes into the clothes receiving cavity, the clothes blocking rib will block the clothes, hindering the user from taking and putting clothes; in addition, during the dehydration process of the clothes treatment device, the clothes blocking rib will prevent the normal discharge of the liquid in the gap area, easily causing the liquid to stay in the gap area and generate an odor, or when the door body is opened, the water staying in the gap area is likely to flow onto the indoor floor plate.

[0051] In the clothes treatment device according to the embodiment of the present application, since the filling member 40 can be switched between an expanded state and a contracted state, selective filling of the gap area 20b between the bottom wall of the clothes inlet 20a and the protruding portion 30a is realized, that is, it can prevent clothes from extending into the gap area 20b, facilitate the user to take out and put clothes from the clothes inlet 20a, and can also reduce the probability that the liquid still stays in the gap area 20b after dehydration, improving the washing and care effect of the clothes treatment device on clothes.

[0052] In the embodiment of the present application, the connection position of the filling member 40 is not limited.

[0053] In some embodiments, please refer to Figures 1 to 4 the figure, the filling member 40 is arranged on the door seal 20 and / or the door body assembly 30. It can be understood that the filling member 40 being arranged on the door seal 20 and / or the door body assembly 30 includes three situations. The first: the filling member 40 is arranged on the door seal 20. The second: the filling member 40 is arranged on the door body assembly 20. The third: the filling member 40 is arranged on both the door seal 20 and the door body assembly 30.

[0054] It should be noted that the volume of the filling member 40 in the expanded state is larger than that in the contracted state. The filling member 40 can be arranged on the door seal 20 and / or the door body assembly 30 in a direct connection or an indirect connection manner.

[0055] In other embodiments, the filling member 40 can be arranged in the gap area 20b and connected to other structures outside the door seal 20 and the door body assembly 30 through a bracket.

[0056] The principle of expansion and contraction of the filling member 40 is not limited.

[0057] In some embodiments, please refer to Figure 5, the filling member 40 has a sealed chamber 41 for accommodating a fluid medium and at least one interface. The sealed chamber 41 introduces or discharges the fluid medium through the interface to adjust the volume of the filling member 40. By changing the volume of the fluid medium in the sealed chamber 41, the filling member 40 expands or contracts. Specifically, when expansion is required, the fluid medium is injected into the sealed chamber 41 through the interface. At this time, the fluid medium fills the sealed chamber 41, and the overall appearance volume of the filling member 40 becomes larger, so that the filling member 40 bulges. When contraction is required, the fluid medium in the sealed chamber 41 is discharged through the interface, thereby reducing or emptying the fluid medium in the sealed chamber 41, and the overall appearance volume of the filling member 40 becomes smaller, so that the filling member 40 contracts.

[0058] It should be noted that the type of the fluid medium is not limited, and it can be a gas, such as air or other gases; it can also be a liquid, such as tap water, brine, etc.

[0059] Exemplarily, the filling member 40 is a flexible film-like structure, which is convenient for expansion and contraction. In some embodiments, please refer to Figure 4 , the filling member 40 includes an airbag, and the space inside the airbag defines the sealed chamber 41. That is to say, in this embodiment, a gas is used as the fluid medium and is filled into the sealed chamber 41; even if the gas leaks, it will not pose risks such as electricity and corrosion to other structures of the laundry treatment device, improving safety; in addition, no additional water source and drainage pipeline are required, and the structure is simple.

[0060] Exemplarily, please refer to Figure 5 , the laundry treatment device further includes a first pump assembly 51. The first pump assembly 51 is connected to one or more of the interfaces and is used to inject the fluid medium into the sealed chamber 41 to make the filling member 40 bulge. It can be understood that the first pump assembly 51 can increase the flow rate of the fluid medium, improve the flow rate of the fluid medium flowing into the sealed chamber 41 through the interface at the same time, and enhance the speed of the filling member 40 switching from the contracted state to the expanded state. At the same time, the first pump assembly 51 can also pressurize the fluid medium flowing into the sealed chamber 41, improve the bulging degree of the filling member 40 when it is in the expanded state, and make the filling member 40 better fill the gap area 20b between the bottom wall of the laundry inlet 20a and the protrusion 30a.

[0061] In the embodiments of the present application, "a plurality of" means not less than two.

[0062] In some embodiments, please refer to Figure 5, the first pump assembly 51 includes a first operating state and a second operating state. In the first operating state, the first pump assembly 51 is used to inject a fluid medium into the sealed chamber 41 to cause the filling member 40 to bulge; in the second operating state, the first pump assembly 51 is used to extract at least part of the fluid medium in the sealed chamber 41 to cause the filling member 40 to contract. In this way, the first pump assembly 51 can accelerate the speed of the fluid medium flowing into the sealed chamber 41, quickly cause the filling member 40 to bulge, and when it is necessary to discharge the fluid medium, accelerate the speed of the fluid medium flowing out of the sealed chamber 41, and can cause the filling member 40 to contract. This not only accelerates the conversion speed of the filling member 40 between the contracted state and the expanded state, but also enables a compact structural arrangement, saves the internal space of the laundry treatment device, and can also save the manufacturing cost of the laundry treatment device.

[0063] In some other embodiments, please refer to Figure 5 , the number of interfaces is multiple, and the multiple interfaces at least include a first interface 42 and a second interface 43. Among them, the first pump assembly 51 is connected to the first interface 42, and the second interface 43 is used to discharge the fluid medium in the sealed chamber. It can be understood that the fluid medium flows out of the sealed chamber 41 through the second interface 43 and flows into the sealed chamber 41 through the first interface 42. The fluid medium flows into and out of the sealed chamber 41 through different interfaces, so that the performance requirements for the first pump assembly 51 can be reduced, and the cost of the first pump assembly 51 can be reduced.

[0064] Exemplarily, the laundry treatment device includes a switching valve assembly disposed at or communicating with the second interface 43. In this way, the switching valve assembly can control the closing or opening of the passage for the fluid medium to flow out of the sealed chamber 41. Specifically, when the filling member 40 is in the expanded state, the switching valve assembly is closed, and the fluid medium in the sealed chamber 41 cannot flow out, so that the filling member 40 remains bulged; when the filling member 40 needs to contract, the switching valve assembly is opened, and the fluid medium in the sealed chamber 41 is discharged from the second interface, so that the filling member 40 can be contracted. In some embodiments, the switching valve assembly can be an electromagnetic valve.

[0065] In some embodiments, please refer to Figure 5, the laundry treatment device further includes a second pump assembly 52. The second pump assembly 52 is connected to the second interface 43 and is used to extract the fluid medium in the sealed chamber 41 through the second interface 43. It can be understood that the second pump assembly 52 can increase the flow rate of the fluid medium, improve the throughput of the fluid medium flowing out of the sealed chamber 41 through the second interface 43 at the same time, and increase the speed of the filler 40 switching from the expanded state to the contracted state, so as to quickly respond to the time requirement of the laundry treatment device switching from the washing program to the dehydration program. In addition, in the embodiment where the fluid medium is a gas, the second pump assembly 52 can reduce the air pressure in the sealed chamber 41 to a negative pressure, so that the filler 40 is continuously subjected to the pressure of the external atmosphere, compressing the volume of the filler 40 when it is in the contracted state, so that the filler 40 can better relieve the filling of the spacer area 20b.

[0066] In some embodiments, please refer to Figure 6 and Figure 7 , the laundry treatment device further includes a drainage passage 60. It can be understood that the drainage passage 60 is used to drain water from the laundry treatment device. For example, it drains to an indoor floor drain, etc.

[0067] The drainage passage 60 includes a closed state and a conducting state. When water is injected into the laundry drum 10, the drainage passage 60 is in the closed state, that is, the water in the laundry treatment device cannot be drained outwards. When the laundry drum 10 drains water, the drainage passage 60 is in the conducting state, and the water in the laundry treatment device is drained through the drainage passage.

[0068] Please refer to Figure 7 , the laundry treatment device further includes a first air chamber structure 61. The first air chamber structure 61 includes a first end 61a and a second end 61b. The position of the first end 61a is higher than that of the second end 61b. Among them, the first end 61a is communicated with the interface, for example, connected to the interface through a pipeline, and the second end 61b is communicated with the drainage passage 60. It can be understood that there is a cavity for accommodating gas inside the first air chamber structure 61. When water is injected into the laundry drum 10, the water enters the upstream of the drainage passage 60 (at this time, the drainage passage 60 is in the closed state), and the liquid flows into the first air chamber structure 61 through the second end 61b, compressing the gas in the first air chamber structure 61, so that the gas in the first air chamber structure 61 flows into the filler 40 through the first end 61a and the interface, so that the filler 40 bulges and enters the expanded state. When the laundry drum 10 drains water, the water in the laundry drum 10 is drained through the drainage passage 60, and the water in the first air chamber structure 61 is drained through the second end 61b. When the drainage passage 60 is substantially emptied, the space of the drainage passage 60 is communicated with the atmospheric environment. Under the combined action of the surface tension of the filler 40 and the atmospheric pressure, the gas inside the filler 40 is discharged through the interface, the first air chamber structure 61, and the drainage passage, so that the filler 40 shrinks and enters the contracted state.

[0069] Exemplarily, please refer to Figure 6 , the connection part of the drainage passage 60 and the laundry treatment cylinder 10 is located at the bottommost part of the laundry treatment cylinder 10. In this way, it is convenient for the liquid in the laundry treatment cylinder 10 to enter the drainage passage 60, and the drainage capacity of the drainage passage 60 is improved.

[0070] In some embodiments, please refer to Figure 7 , the laundry treatment device includes a pipe joint 601 and a liquid level sensor 62, and the internal space of the pipe joint 601 forms a part of the drainage passage 60.

[0071] The liquid level sensor 62 includes a second air chamber structure 621 and an electrical component. One end of the second air chamber structure 621 and the second end 61b of the first air chamber structure 61 are respectively connected to the pipe joint 601, and the electrical component is used to generate different frequency signals according to the pressure change of the second air chamber structure 621. It can be understood that when water is injected into the laundry treatment cylinder 10, the liquid water enters the interior of the pipe joint 601, and the water enters the second air chamber structure 621 through one end of the second air chamber structure 621. The electrical component senses the pressure change in the second air chamber structure 621 and generates signals of different frequencies, and the control system of the laundry treatment device calculates the current liquid level height of the laundry treatment device according to the frequency signals.

[0072] In some embodiments, please refer to Figure 8 and Figure 9 , the filling member 40 is arranged on the door seal 20. For example, it is arranged on the side wall of the laundry inlet 20a. The filling member 40 in the expanded state extends along the circumference of the side wall of the laundry inlet 20a, and the corresponding central angle is not less than 30°, such as 30°, 40°, 50°, 60°, 90°, 120° or 150°, etc. It should be noted that the central angle refers to the central angle corresponding to the arc extending from one end of the filling member 40 to the other end. In this way, when the filling member 40 is in the expanded state, it can block the laundry from entering the spaced area 20b in a relatively large area.

[0073] In some embodiments, please refer to Figure 8 , the door seal 20 has a groove 20c adapted to the filling member 40 for receiving the filling member 40 in the contracted state. In this way, when the filling member 40 is in the contracted state, the filling member 40 can retract into the groove 20c. The groove 20c can protect the filling member 40, reduce the risk of the filling member 40 being damaged when the user puts in or takes out the laundry, and at the same time, it can also make the filling member 40 release the filling of the spaced area 20b as much as possible, reduce the obstruction of the filling member 40 to the user when putting in or taking out the laundry, and improve the user experience.

[0074] Exemplarily, when the filling member 40 is in a contracted state, the filling member 40 can be fully retracted into the groove 20c. In this way, when the filling member 40 is in the contracted state, it will not protrude from the inner circumferential surface of the clothing inlet 20a. Thus, the internal space of the groove 20c is fully utilized, enabling the filling member 40 to be protected as much as possible. At the same time, the probability of other components such as clothes rubbing against the filling member 40 is also reduced.

[0075] In some embodiments, refer to Figure 8 and Figure 9 , when the filling member is in an expanded state, the groove 20c extends circumferentially along the side wall of the clothing inlet 20a, and the corresponding central angle is not less than 30°. In this way, the groove 20c can make full use of the arc length of the side wall of the clothing inlet 20a, increasing the size of the groove 20c so that the groove 20c has sufficient internal space to accommodate the filling member 40 in the contracted state, improving the protective ability of the groove 20c for the filling member 40.

[0076] In some embodiments, refer to Figure 9 , when the filling member 40 is in an expanded state, the projection L2 of the length of the filling member 40 along the axial direction of the clothing treatment cylinder 10 on the clothing inlet 20a is not less than 1 / 2 of the length L1 of the clothing inlet 20a. In this way, when the filling member 40 is in the expanded state, the filling member 40 can make full use of the axial length L1 of the clothing inlet 20a, filling as much as possible the interval region 20b between the bottom wall of the clothing inlet 20a and the protruding portion 30a, enhancing the filling effect of the filling member 40 and improving the ability of the filling member 40 to prevent clothes from falling into the interval region 20b.

[0077] Exemplarily, refer to Figure 9 , when the filling member 40 is in an expanded state, the projection L2 of the length of the filling member 40 along the axial direction of the clothing treatment cylinder 10 on the clothing inlet 20a is not greater than the length L1 of the clothing inlet 20a. In this way, when the filling member 40 is in the expanded state, a safety distance can be left between the filling member 40 and the clothing accommodation cavity 10a to reduce the influence of the filling member 40 on the clothing accommodation cavity 10a during the process of treating clothes, and at the same time, reduce the influence of the rotation of the clothing treatment cylinder 10 on the filling member 40.
