Description

Technical Field

[0001] The present application relates to the field of clothing processing, and in particular to an opening and closing valve for a liquid container, a liquid container, and clothing processing equipment. Background Art

[0002] CN113215778A discloses a laundry treatment agent box and a washing machine. The laundry treatment agent box is mounted on the washing machine and is used to add wash water to the washing tub. The laundry treatment agent box comprises a box body and an upper cover. The box body is provided with at least one receiving chamber. The upper cover is located above the box body and is provided with a water inlet for supplying water to the receiving chamber. First, laundry treatment agent is added to the receiving chamber. Then, tap water is added to the receiving chamber through the water inlet to dilute and dissolve the laundry treatment agent in the receiving chamber, allowing it to flow into the washing tub of the washing machine. A siphon structure is provided within the receiving chamber to allow the liquid in the receiving chamber to flow out through the siphon.

[0003] This prior art solves the problem of water accumulation in the laundry treatment agent box after the washing machine has finished running. However, this laundry treatment agent box is suitable for situations where laundry treatment agent is manually added and used up in a single use. It is not suitable for storing laundry treatment agent in batches for multiple uses.

[0004] CN112553840A discloses a liquid storage box that reduces liquid residue. The liquid storage box has a liquid extraction port at its bottom, and a liquid extraction channel within the liquid extraction port. A one-way valve assembly is installed within the liquid extraction channel to open or close its outlet. The one-way valve assembly includes a movable valve core, a spring, and a fixed seat. The fixed seat is fixed to the top of the liquid extraction port via a plurality of circumferentially arranged brackets. One end of the movable valve core is movably inserted into a guide cavity within the fixed seat. The other end of the movable valve core has a plugging head for opening or closing the outlet of the liquid extraction channel. A spring is sheathed on the outside of the movable valve core, and the two ends of the spring are connected to the fixed seat and the plugging head, respectively.

[0005] In this prior art, when the one-way valve assembly switches from open to closed (for example, when removing the liquid storage box from the washing machine), a large amount of residual liquid will flow out of the flow channel, causing liquid waste and a poor user experience.

[0006] More specifically, for example, referring to FIG. 3 of CN112553840A , residual liquid is generated during the process of the one-way valve assembly (hereinafter sometimes referred to as the valve) switching from open to closed. When the liquid storage cartridge is removed from the washing machine, the valve switches from open to closed. Due to the increased clearance between the valve and the mating connector, a local negative pressure is generated at the location of the connector. This causes a significant amount of liquid in the liquid extraction channel (i.e., the liquid within the housing) to be drawn out, resulting in a large amount of residual liquid.

[0007] Additionally, the sealing capability of the fluid reservoir may be insufficient. Utility Model Content

[0008] This application is made in view of the above-mentioned state of the prior art. The purpose of this application is to provide a novel opening and closing valve for a liquid container, a liquid container and a clothes processing device.

[0009] The present application provides an on-off valve for a liquid container, which includes an on-off valve housing, an on-off rod, a first seal, and a second seal.

[0010] The opening and closing rod includes a liquid pumping channel rod, the liquid pumping channel rod partially extends out of the opening and closing valve housing and forms a sealed sliding connection with the opening and closing valve housing.

[0011] The opening and closing rod can move axially relative to the opening and closing valve housing to open or close the opening and closing valve.

[0012] The opening and closing rod has a valve core portion, and the first seal is installed on the valve core portion and is used to seal the flow channel when the opening and closing valve is closed.

[0013] The second seal is integrally formed with the opening and closing valve housing and cooperates with the liquid pumping channel rod to perform normal sealing.

[0014] The liquid pumping channel rod is formed with a liquid pumping channel, the liquid inlet end of the liquid pumping channel is located in the opening and closing valve housing, between the first seal and the second seal, and the liquid outlet end of the liquid pumping channel is located outside the opening and closing valve.

[0015] In the above scheme, when the on-off valve is open, the first seal is released (unsealed), and the liquid inlet end of the liquid extraction channel is connected to the interior of the liquid container. When the on-off valve is closed, the first seal is sealed, and the liquid inlet end of the liquid extraction channel is not connected to the interior of the liquid container. The second seal is permanently sealed and is in sealing and sliding connection with the on-off rod. When the on-off valve is open, liquid can flow and the pressure in the liquid container is stable. When the on-off valve is closed, if the pressure in the liquid container increases due to environmental factors, the second seal has the effect of strengthening the seal, ensuring that the seal of the liquid container will not fail when the pressure in the liquid container is high.

[0016] The liquid extraction channel rod forms a liquid extraction channel for downwardly discharging liquid from the interior of the on-off valve housing. The liquid inlet end of the liquid extraction channel is located below the valve core (first seal). When the on-off valve is open, the liquid extraction channel can discharge liquid from the on-off valve. When the on-off valve is closed, the valve core (first seal) separates the liquid extraction channel from the space within the on-off valve, preventing the liquid from being discharged. Thus, embodiments of the present application provide a novel on-off valve structure.

[0017] On the other hand, the liquid extraction channel rod used as the valve stem is formed with a liquid extraction channel, and the space inside the opening and closing valve can be smaller. During the process of switching from valve opening to closing, the residual liquid remaining in the flow channel (especially in the opening and closing valve) can be less. When the opening and closing valve is closed, the valve core separates the liquid extraction channel from the space inside the opening and closing valve, and the liquid in the opening and closing valve cannot be discharged, which can reduce the outflow of residual liquid and avoid liquid waste.

[0018] Optionally, the on-off valve for the liquid container further comprises a siphon cap, the siphon cap being arranged around the on-off valve housing, a siphon gap being formed between the siphon cap and the on-off valve housing, and a siphon hole being formed in the on-off valve housing to connect the siphon gap with the interior of the on-off valve housing.

[0019] The bottom of the siphon cap is provided with a liquid extraction port, and the liquid extraction port is located at the lowest point of the liquid level of the liquid container.

[0020] In the above solution, the siphon effect can ensure that the liquid in the liquid container is drained cleanly, and the liquid in the liquid container can be used more economically and efficiently.

[0021] Optionally, the on-off valve shell includes an on-off valve lower shell and an on-off valve upper shell, the on-off valve lower shell and the on-off valve upper shell are connected together to form the on-off valve shell, the on-off valve lower shell and the on-off valve upper shell are snap-connected, and the siphon hole is formed at the snap-connected position.

[0022] In the above solution, the lower shell of the on-off valve and the upper shell of the on-off valve are connected by a snap-fit ​​connection, which is simple and easy to assemble. A siphon hole is formed at the snap-fit ​​connection position, so that one component can realize multiple functions and simplify the structure of the on-off valve shell.

[0023] Optionally, the upper shell of the on-off valve forms a sliding guide assembly with the siphon cap on the upper side of the snap connection position.

[0024] In the above solution, the on-off valve upper shell of the on-off valve is supported on the siphon cap, and the on-off valve has good structural stability and is easy to assemble.

[0025] Optionally, the on-off valve is used to be installed on the annular mounting portion of the liquid container, and the siphon cap has a sleeve portion for sleeved on the annular mounting portion.

[0026] The on-off valve lower shell has an inserting lower end for being inserted into the annular mounting portion.

[0027] This installation method has a simple and compact structure and is convenient for reducing the flow channel space in the on-off valve.

[0028] Optionally, the on-off valve further includes a third sealing ring, which is mounted on the lower shell of the on-off valve and is used to form a seal with the annular mounting portion when the on-off valve is mounted on the liquid container.

[0029] In the above solution, the third sealing ring can improve the sealing performance of the on-off valve and prevent unexpected liquid leakage.

[0030] Optionally, the first seal is a rubber seal ring, the second seal is made of rubber and includes one or more sealing lips, and the third seal ring is a rubber piece.

[0031] In this way, the rubber seal is low-cost and can achieve a good, long-lasting seal.

[0032] Optionally, the opening and closing valve also includes a spring, and the opening and closing rod also has a guide rod and a spring seat located between the guide rod and the liquid pumping channel rod. The spring is installed under pressure between the spring seat and the upper end of the opening and closing valve housing, and the guide rod and the opening and closing valve housing form a sliding guide installation.

[0033] In the above solution, when the opening and closing rod is not lifted, the spring can ensure the closure of the opening and closing valve, which facilitates the sealing of the liquid container before use (for example, during transportation or storage before installation in the clothing processing device) and avoids unexpected liquid leakage.

[0034] The present application also provides a liquid container, comprising:

[0035] an annular mounting portion located at the bottom of the liquid container, the annular mounting portion defining a liquid outlet; and

[0036] According to the on-off valve of the present application, the on-off valve is mounted on the annular mounting portion, and the liquid extraction channel rod extends into the annular mounting portion, thereby being used to discharge liquid to the liquid outlet.

[0037] Here, the liquid container has corresponding effects or advantages because it has the above-mentioned opening and closing valve. In addition, the opening and closing valve and the liquid container have simple structures and are easy to install.

[0038] The present application also provides a clothes processing device, comprising:

[0039] one or more liquid containers according to the present application; and

[0040] a container mounting joint for drawing out the liquid in the liquid container,

[0041] When the liquid container is mounted on the clothes processing device, the container mounting joint pushes up the opening and closing rod to open the opening and closing valve.

[0042] Here, the laundry processing device has corresponding effects or advantages due to the presence of the liquid container. In addition, the opening and closing valve can be opened by the container mounting joint for drawing out the liquid in the liquid container, so that one component can realize multiple functions, with fewer parts, simple structure, and easy use.

[0050] Description of Reference Numerals DETAILED DESCRIPTION

[0051] The following describes exemplary embodiments of the present application with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible embodiments of the present application, nor to limit the scope of the present application.

[0052] See also Figures 1 to 3A In one aspect, the present application provides a laundry processing apparatus, which may include one or more liquid containers 110 , 120 .

[0053] Here, for example, the multiple liquid containers 110 and 120 can respectively contain different liquids, such as laundry detergent, softener, disinfectant, care agent, water, etc. The clothes processing device can use liquids in different liquid containers according to actual needs.

[0054] Here, the clothes processing device may be various types of clothes processing devices, for example, a clothes cleaning device, a clothes drying device, or a clothes processing device having both washing and drying functions.

[0055] See also Figures 1 to 4C , especially Figure 3B and Figure 4B The liquid containers 110 and 120 of the embodiment of the present application may include an opening and closing valve 124.

[0056] Taking the liquid container 120 as an example, the opening and closing valve 124 thereof will be first introduced.

[0057] The on-off valve 124 for a liquid container may include an on-off valve housing, an on-off rod 43 , a first seal 45 , and a second seal 47 .

[0058] The opening and closing rod 43 may include a liquid extraction channel rod 431 that partially extends from the opening and closing valve housing and forms a sealed sliding connection with the opening and closing valve housing. The opening and closing rod 43 can move axially relative to the opening and closing valve housing to open or close the opening and closing valve 124. The opening and closing rod 43 may have a valve core portion 435. A first seal 45 is mounted on the valve core portion 435 to seal the flow channel when the opening and closing valve 124 is closed. A second seal 47 may be integrally formed with the opening and closing valve housing and cooperate with the liquid extraction channel rod 431 to provide a normal sealing.

[0059] It will be understood that the second seal 47 and the on-off valve housing are integrally formed, meaning that the two are inseparably connected together and can be made of the same or different materials. For example, the second seal 47 can be bonded (e.g., by vulcanization bonding) to the on-off valve housing. The second seal 47 being integrally formed with the on-off valve housing includes the second seal 47 being integrally formed with a portion of the on-off valve housing.

[0060] It is understood that the normal sealing here means that the second seal 47 plays a sealing role when the on-off valve 124 is opened and closed. Figure 3B and Figure 4B The second seal 47 realizes the seal between the opening and closing valve housing and the opening and closing rod 43 (the outer peripheral surface).

[0061] The liquid extraction channel rod 431 is formed with a liquid extraction channel 434. The liquid inlet end 433 of the liquid extraction channel 434 (see Figure 4C ) is located in the on-off valve housing, in the axial direction of the on-off valve 124 ( Figure 3B and Figure 4B In the substantially vertical direction), the liquid inlet end 433 is between the first seal 45 and the second seal 47, and the liquid outlet end of the liquid extraction channel 434 is located outside the opening and closing valve 124. Here, without limitation, the liquid outlet end of the liquid extraction channel 434 can be formed at the lower end of the liquid extraction channel rod 431.

[0062] A valve seat portion 411 may be formed at the lower end portion of the on-off valve housing for cooperating with the valve core portion 435 (first seal 45 ) to close the on-off valve 124 .

[0063] In the above embodiment, the on-off valve 124 is open (see Figure 3B ), the first seal between the first seal 45 and the opening and closing valve housing is released (unsealed), and the liquid inlet end 433 of the liquid extraction channel 434 is connected to the liquid container 120 (see Figures 1 to 3A ) is connected to the inside, the on-off valve 124 is closed (see Figure 4B ), the first seal is sealed, and the liquid inlet end 433 of the liquid extraction channel 434 is not connected to the interior of the liquid container 120. The second seal is permanently sealed and is in sealed sliding connection with the opening and closing rod 43. When the opening and closing valve 124 is open, liquid can flow and the pressure in the liquid container 120 is stable. When the opening and closing valve 124 is closed, if the pressure in the liquid container 120 increases due to environmental factors, the second seal 47 strengthens the seal, ensuring that the seal of the liquid container 120 will not fail even when the pressure in the liquid container 120 is high.

[0064] The liquid extraction channel rod 431 is formed with a liquid extraction channel 434 for discharging liquid from the interior of the on-off valve housing downward. The liquid inlet end 433 of the liquid extraction channel 434 is located below the valve core portion 435 (first seal 45). When the on-off valve 124 is open, the liquid extraction channel 434 can discharge the liquid from the on-off valve 124. When the on-off valve 124 is closed, the valve core portion 435 (first seal 45) separates the liquid extraction channel 434 from the space within the on-off valve 124, preventing the liquid from being discharged from the on-off valve 124. Thus, the embodiments of the present application provide a novel on-off valve structure.

[0065] On the other hand, the liquid extraction channel rod 431 used as the valve stem is formed with a liquid extraction channel 434, and the space inside the on-off valve 124 can be smaller. During the process of switching from valve opening to closing, the residual liquid remaining in the flow channel, especially in the on-off valve 124, can be less. When the on-off valve 124 is closed, the valve core part 435 separates the liquid extraction channel 434 from the space inside the on-off valve 124, and the liquid in the on-off valve 124 cannot be discharged, which can reduce the outflow of residual liquid and avoid liquid waste.

[0066] Alternatively, see Figure 3B The on-off valve 124 may further include a siphon cap 48, which may be disposed around the on-off valve housing. A siphon gap is formed between the siphon cap 48 and the on-off valve housing. The on-off valve housing is provided with a siphon hole 410 connecting the siphon gap and the interior of the on-off valve housing.

[0067] See also Figure 4A The bottom of the siphon cap 48 may be provided with a liquid extraction port 481 , and the liquid extraction port 481 may be located at the lowest point of the liquid level in the liquid container 120 .

[0068] In the above embodiment, the siphon effect can ensure that the liquid in the liquid container 120 is drained cleanly, and the liquid in the liquid container 120 can be used more economically and efficiently.

[0069] Alternatively, see Figure 3B The on-off valve housing may include an on-off valve lower housing 41 and an on-off valve upper housing 42. The on-off valve lower housing 41 and the on-off valve upper housing 42 are connected together to form the on-off valve housing. The on-off valve lower housing 41 and the on-off valve upper housing 42 may be snap-connected, and a siphon hole 410 is formed at the snap-connected position.

[0070] In the above embodiment, the on-off valve lower shell 41 and the on-off valve upper shell 42 are connected by snap fastening, which is simple and easy to assemble. A siphon hole is formed at the snap fastening position, so that one component can realize multiple functions and simplify the structure of the on-off valve shell.

[0071] In another non-limiting example, the opening and closing valve housing may be an integral structure, for example, integrally formed by injection molding.

[0072] Alternatively, see Figure 3B The on-off valve upper shell 42 forms a sliding guide assembly with the siphon cap 48 on the upper side of the buckle connection position. For example, a guide flange 421 can be provided on the upper side of the buckle connection position of the on-off valve upper shell 42.

[0073] In the above embodiment, the on-off valve upper shell 42 of the on-off valve 124 is supported by the siphon cap 48 , so the on-off valve 124 has good structural stability and is easy to assemble.

[0074] Alternatively, see Figure 3A and Figure 3B The on-off valve 124 can be installed on the annular mounting portion 1211 of the liquid container 120, the siphon cap 48 can have a sleeve portion 483 for being sleeved on the annular mounting portion 1211, and the on-off valve lower shell 41 can have a plug-in lower end for being inserted into the annular mounting portion 1211.

[0075] This installation method has a simple and compact structure and is convenient for reducing the flow channel space in the on-off valve 124 .

[0076] The annular mounting portion 1211 may extend upward from the bottom wall of the liquid container 120. The lower end of the annular mounting portion 1211 forms an opening.

[0077] Also refer to Figure 4A A structure that engages with the annular mounting portion 1211 may be formed on the siphon cap 48 so that the siphon cap 48 is fixed to the annular mounting portion 1211 in its axial and circumferential directions. Here, the engaging structure of the siphon cap 48 may be an engaging hole 482 .

[0078] Alternatively, see Figure 3B The on-off valve 124 may further include a third sealing ring 46 , which is mounted on the on-off valve lower shell 41 and is used to form a seal with the annular mounting portion 1211 when the on-off valve 124 is mounted to the liquid container 120 .

[0079] In the above embodiment, the third sealing ring 46 can improve the sealing performance of the on-off valve 124 and prevent unexpected liquid leakage.

[0080] Alternatively, see Figure 3B The first seal 45 can be a rubber seal ring. The second seal 47 can be made of rubber and include one or more sealing lips. The third seal 46 can be a rubber member, such as a rubber seal ring. The sealing lip on the lower side of the second seal 47 can contact and seal with the liquid withdrawal channel rod 431.

[0081] Rubber seals are low cost and provide a good, long-lasting seal.

[0082] Alternatively, see Figure 3B 、 Figure 4B and Figure 4C The on-off valve 124 may further include a spring 44. The on-off rod 43 may further include a guide rod 436 and a spring seat 432 located between the guide rod 436 and the liquid extraction channel rod 431. The spring 44 is installed under pressure between the spring seat 432 and the upper end of the on-off valve housing. The guide rod 436 and the on-off valve housing form a sliding guide. Here, the spring 44 may be, for example, a coil spring. The guide rod 436 can be inserted into a guide hole in the on-off valve upper housing 42.

[0083] Optionally, a plurality of guide protrusions 437 may be provided on the outer periphery of the spring seat 432 , and the guide protrusions 437 may form a sliding guide installation with the on-off valve lower shell 41 .

[0084] In the above embodiment, when the opening and closing rod 43 is not lifted up, the spring 44 can ensure the closure of the opening and closing valve 124, thereby facilitating the sealing of the liquid container 120 before use (for example, during transportation or storage before being installed in the clothing processing equipment) and avoiding unexpected liquid leakage.

[0085] The on-off valve of the embodiment of the present application leaves only a small amount of residual liquid in the liquid extraction channel during the switching process from open to closed. In a comparative example, the residual liquid amount can be a fraction of that of a conventional on-off valve. In one example, the residual liquid of the on-off valve of the embodiment of the present application can be less than 0.1g (gram).

[0086] The liquid container 120 according to the embodiment of the present application is further described below. Figures 1 to 3B As shown, the liquid container 120 may include an annular mounting portion 1211 located at the bottom of the liquid container 120 , and the annular mounting portion 1211 may define a liquid outlet 123 .

[0087] The on-off valve 124 can be installed on the annular mounting portion 1211 , and the liquid extraction channel rod 431 extends into the annular mounting portion 1211 , thereby being used to discharge liquid to the liquid outlet 123 .

[0088] In the liquid container, the liquid container has corresponding effects or advantages because it has the above-mentioned opening and closing valve 124. In addition, the opening and closing valve 124 and the liquid container 120 have simple structures and are easy to install.

[0089] The liquid container 120 may include a container body 121 and a container cover 122 , and an annular mounting portion 1211 may be formed at the bottom of the container body 121 .

[0090] The container body 121 may have a liquid filling port, and a filter 125 may be provided in the liquid filling port.

[0091] The laundry treating apparatus according to the embodiment of the present application may include one or more of the above-mentioned liquid containers 110 , 120 and a container mounting joint for drawing out the liquid in the liquid containers 110 , 120 .

[0092] When the liquid containers 110 and 120 are mounted on the clothes processing apparatus, the container mounting joint pushes up the opening and closing rod 43 of the opening and closing valve 124 to open the opening and closing valve 124 .

[0093] In this laundry processing device, the laundry processing device has corresponding effects or advantages due to the presence of the liquid container. In addition, the opening and closing valve 124 can be opened by a container mounting joint for drawing out the liquid in the liquid container. This allows a single component to perform multiple functions, resulting in a small number of parts, a simple structure, and ease of use.

[0094] See also Figure 1 The clothes treating apparatus may include one or more installation boxes 100 , and one or more liquid containers may be installed on one installation box 100 . Figure 1 1 and 2. In the embodiment of the present invention, two liquid containers 110, 120 are installed on a mounting box 100. The two liquid containers 110, 120 can have the same or different structures. Here, the two liquid containers 110, 120 can especially store different liquids.

[0095] The container mounting connector can be connected to a corresponding pipeline to supply liquid into, for example, a laundry treatment tub.

[0096] In the above embodiment, the installation and removal of the liquid container does not affect the connection between the container installation joint and the corresponding pipeline, and liquid leakage is not likely to occur.
