A laundry treating apparatus

Abstract

Embodiments of the present application provide a laundry treating apparatus including a tub assembly and a circulation system. The tub assembly is provided with a laundry treating cavity and a drain opening communicating with the laundry treating cavity. The circulation system includes a drain pump having a first outlet and a water inlet, a drain passage communicating the drain opening with the water inlet, and a first passage having a water inlet end communicating with the first outlet and a water outlet end facing the drain passage. During the process of the drain pump pumping water into the first passage, the water in the first passage flows at a high speed, and the water flowing out of the water outlet end of the first passage has a flow interference effect on the water and the detergent in the drain passage, which is conducive to promoting the dissolution of the detergent in the drain passage. Since the drain passage communicates with the laundry treating cavity through the drain opening, the dissolved detergent will enter the laundry treating cavity along with the water through the drain opening to clean the laundry, thereby helping to improve the cleaning ratio.

Description

Technical Field

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

[0002] In related technologies, the drainage channel of the garment processing equipment is connected to the drum assembly through the drain outlet. During the washing process, because the density of detergent is greater than that of water, the detergent that is not dissolved in time will sink to the bottom of the drum assembly. Some detergent will sink into the drainage channel through the drain outlet. The rotation of the inner drum has little effect on the detergent that sinks into the drainage channel. That is, the detergent in the drainage channel will not dissolve with the rotation of the inner drum, thus affecting the washing ratio of the garment processing equipment. Utility Model Content

[0003] In view of this, embodiments of this application aim to provide a garment processing device that helps to promote the dissolution of detergent in the drain channel, thereby improving the washing ratio.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0005] This application provides a garment processing device, including:

[0006] A tubular assembly, wherein the tubular assembly is provided with a garment processing chamber and a drain outlet communicating with the garment processing chamber;

[0007] A circulation system includes a drain pump, a drain channel, and a first channel. The drain pump has a first outlet and an inlet. The drain channel connects the drain outlet and the inlet. The inlet end of the first channel is connected to the first outlet, and the outlet end of the first channel faces the drain channel to discharge water.

[0008] In some implementations, the sidewall of the drainage channel is provided with an opening, and the outlet end of the first channel is sealed to the opening.

[0009] In some embodiments, the cylindrical assembly includes an outer cylinder and an inner cylinder, the inner cylinder being disposed inside the outer cylinder, the drain outlet being disposed in the outer cylinder, and the water outlet of the first channel being located between the outer circumferential surface of the inner cylinder and the inner circumferential surface of the outer cylinder, and discharging water toward the drain outlet.

[0010] In some implementations, the projection of the water outlet of the first channel onto a plane perpendicular to the height of the garment processing device at least partially overlaps with the projection of the drain outlet.

[0011] In some implementations, the outlet end of the first channel extends into the drain outlet.

[0012] In some implementations, the circulation system includes a second channel, the inlet of which is connected to the first outlet, and the outlet of which flows toward the garment processing chamber.

[0013] In some implementations, the garment handling device includes a door seal ring disposed at the front end of the tubular assembly, and the water outlet of the second channel is disposed at the door seal ring.

[0014] In some embodiments, the garment processing device includes a door glass bowl, and at least one outlet of the second channel is located on the upper part of the door seal ring for discharging water toward the interior of the garment processing chamber and / or the door glass bowl.

[0015] In some implementations, at least one outlet of the second channel is located at the bottom of the inner circumferential surface of the door seal ring; when the drainage pump is in a stopped state, the second channel is also used to guide the water accumulated in the door seal ring to the drainage pump.

[0016] In some implementations, the circulation system includes a main pipeline and multiple branch pipelines, with the inlet ends of at least two of the branch pipelines connected to the main pipeline, and the inlet end of the main pipeline being sealed to the first outlet.

[0017] One of the branch pipes defines a portion of the first channel, and at least one of the branch pipes defines a portion of the second channel.

[0018] In some embodiments, the garment processing device includes a water outlet channel, the drain pump has a second outlet, one end of the water outlet channel is connected to the second outlet, and the water outlet channel is used to discharge water from the garment processing device when the water inlet is connected to the second outlet.

[0019] In some embodiments, the garment handling device includes a first corrugated pipe, the space within which defines the drainage channel.

[0020] The clothing processing device provided in this application embodiment has water in the clothing processing chamber flowing through the drain outlet to the drain channel, and then through the drain channel to the drain pump. During the process of the drain pump pumping water into the first channel, the water flow rate in the first channel is relatively fast, so that the water flowing out of the outlet of the first channel has a turbulent effect on the water and detergent in the drain channel, which is conducive to promoting the dissolution of detergent in the drain channel. Since the drain channel is connected to the clothing processing chamber through the drain outlet, the dissolved detergent will enter the clothing processing chamber with the water through the drain outlet to clean the clothes, thereby helping to improve the washing ratio.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0030] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0031] This application provides a garment processing device. Please refer to... Figure 1 and Figure 3 The garment processing equipment includes a cylindrical assembly 10, which has a garment processing chamber 10a. The garment processing chamber 10a is used to hold garments.

[0032] The tubular assembly 10 is also provided with a drain outlet that communicates with the garment processing chamber 10a.

[0033] It is understood that the specific structure of the tubular assembly 10 is not limited. For example, in some embodiments, the tubular assembly 10 includes an outer tub 11 and an inner tub, with the inner tub disposed inside the outer tub 11. The outer tub 11 is used to hold water, and the space inside the inner tub forms a clothing processing chamber 10a. In this embodiment, the inner tub holds water through the outer tub 11. The inner tub can also be referred to as a perforated inner tub, and the drain outlet is located on the outer tub 11.

[0034] For example, the garment processing equipment includes a circulation system; see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The circulation system includes a drain pump 21, a drain channel 22, and a first channel 23. The drain pump 21 has a first outlet and a water inlet, and the drain channel 22 connects the drain outlet and the water inlet. Thus, water in the clothing processing chamber 10a flows into the drain channel 22 through the drain outlet, and then flows into the drain pump 21 through the water inlet. That is, the drain channel 22 is used to guide the water in the clothing processing chamber 10a to the drain pump 21.

[0035] The inlet of the first channel 23 is connected to the first outlet, and the outlet of the first channel 23 faces the drain channel 22. Thus, water from the drain pump 21 can be discharged through the first outlet to the first channel 23, and the outlet of the first channel 23 faces the drain channel 22. In other words, the first channel 23 is used to guide the water from the drain pump 21 back to the drain channel 22. Furthermore, during the process of the drain pump 21 pumping water into the first channel 23, the water flow rate in the first channel 23 is relatively fast, causing the water flowing out of the outlet of the first channel 23 to have a turbulent effect on the water and detergent in the drain channel 22, which helps to promote the dissolution of the detergent in the drain channel 22. Since the drain channel 22 is connected to the clothes processing chamber 10a through the drain outlet, the dissolved detergent will enter the clothes processing chamber 10a along with the water through the drain outlet to clean the clothes, thereby helping to improve the washing ratio.

[0036] It should be noted that the water outlet of the first channel 23 faces the drain channel 22, which means that the water in the first channel 23 can flow directly into the drain channel 22 to turbulently move the water and detergent in the drain channel 22. This can be a partial flow of water in the first channel 23 into the drain channel 22, or all the water in the first channel into the drain channel 22; or the water in the first channel 23 can flow towards the vicinity of the drain channel 22, and the faster flow of water in the first channel 23 can drive the water near the drain channel 22 to quickly enter the drain channel 22, thus turbulently moving the water and detergent in the drain channel 22.

[0037] There are no restrictions on the type of clothing processing equipment, such as washing machines, washer-dryer combos, etc.

[0038] The structure or form of the drainage channel 22 is not limited. For example, in some embodiments, please refer to... Figure 1 and Figure 3 The garment processing equipment includes a first corrugated pipe 50, the space within which defines a drainage channel 22. The corrugated pipe has multiple stretchable corrugations, possessing a strong ability to undergo elastic deformation. It can generate displacement under pressure, axial force, lateral force, or bending moment, exhibiting strong impact resistance and reducing the impact of pipe length changes caused by temperature variations on the garment processing equipment. Due to the corrugated pipe's extensibility and elastic deformation capabilities, even if the drain outlet and the inlet of the drain pump 21 are not aligned, a connection can still be achieved through the first corrugated pipe 50.

[0039] In some embodiments, please refer to Figure 1 and Figure 3The garment processing equipment includes a water outlet channel 40 and a drain pump 21 with a second outlet. One end of the water outlet channel 40 is connected to the second outlet. The water outlet channel 40 is used to discharge water from the garment processing equipment when the water inlet is connected to the second outlet. That is, the water outlet channel 40 is used to discharge the water in the drain pump 21 to the outside of the garment processing equipment.

[0040] Specifically, the connection state of the drainage pump 21 includes at least a first state and a second state.

[0041] In the first state, the drain pump 21 connects the inlet and the first outlet, and closes the second outlet. In the second state, the drain pump 21 connects the inlet and the second outlet. In this state, the first outlet can be open, or it can be closed.

[0042] Specifically, when the garment processing equipment is in the washing state, the drain pump 21 is in the first state, with the inlet connected to the first outlet and the second outlet closed. The drain pump 21 circulates water to the drain channel 22, which helps to improve the washing ratio. When the garment processing equipment needs to drain water, the drain pump 21 is in the second state, with the inlet connected to the second outlet, and the drain pump 21 discharges water from the garment processing equipment.

[0043] In some embodiments, please refer to Figure 1 and Figure 2 The side wall of the drain channel 22 has an opening, and the outlet end of the first channel 23 is sealed to the opening. In this way, all the water flowing out of the outlet end of the first channel 23 can enter the drain channel 22, which helps to enhance the turbulence of water and detergent in the drain channel 22, and is more conducive to accelerating the dissolution of detergent in the drain channel 22, thereby helping to further improve the washing ratio.

[0044] In this embodiment, since the water outlet of the first channel 23 is sealed to the opening, the first channel 23 can be located completely outside the cylinder assembly 10, thereby minimizing the occupation of the internal space of the cylinder assembly 10 by the first channel 23.

[0045] The structure or form of the first channel 23 is not limited. For some embodiments, please refer to... Figure 1 The garment processing equipment includes a second corrugated pipe 60, the internal space of which defines at least a portion of the first channel 23.

[0046] In other embodiments, the water outlet of the first channel 23 is located between the outer circumferential surface of the inner tub and the inner circumferential surface of the outer tub 11, and water flows out towards the drain outlet. In this embodiment, the water outlet of the first channel 23 is located inside the outer tub 11. In this case, at least a portion of the water flowing out of the water outlet of the first channel 23 can be guided to the drain channel 22 through the drain outlet, thereby creating a turbulence effect on the water and detergent in the drain channel 22.

[0047] In some embodiments, please refer to Figure 4 The first channel 23 passes through the front wall of the outer tub 11, such that the outlet end of the first channel 23 is located between the outer circumferential surface of the inner tub and the inner circumferential surface of the outer tub 11. It is understood that in some other embodiments, the first channel 23 may also pass through the rear wall of the outer tub 11.

[0048] In some embodiments, the drain outlet is located on the side wall of the outer tub 11, and at least part of the water outlet of the first channel 23 is higher than the drain outlet and flows out toward the drain outlet. In this case, as the water in the first channel 23 flows toward the drain channel 22, it can also play a certain role in disturbing the water and detergent near the drain channel 22 inside the outer tub 11, and can also accelerate the dissolution of some detergent inside the outer tub 11. At the same time, it can also cause the water near the drain channel 22 to enter the drain channel 22 at a faster speed, thereby disturbing the water and detergent in the drain channel 22, which helps to improve the washing ratio.

[0049] In this embodiment, the drain outlet can be located at the lowest point of the circumference of the outer tub 11, so that the water in the outer tub 11 can be discharged into the drain channel 22 through the drain outlet.

[0050] In other embodiments, the drain outlet may also be located on the rear wall of the outer tub 11. In this case, the water outlet of the first channel 23 flows out toward the drain outlet located on the rear wall of the outer tub 11.

[0051] In some embodiments, the projection of the water outlet of the first channel 23 onto a plane perpendicular to the height of the garment handling device at least partially overlaps with the projection of the drain outlet. This facilitates water outlet of the first channel 23 facing the drain outlet.

[0052] For example, the outlet end of the first channel 23 extends into the drain outlet. This helps to ensure that as much water as possible in the first channel 23 enters the drain channel 22, which helps to enhance the turbulence effect on the water and detergent in the drain channel 22.

[0053] In this embodiment, when projected onto a plane perpendicular to the height direction, the projection of the water outlet end of the first channel 23 falls within the projection range of the drain outlet.

[0054] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The circulation system includes a second channel 24, the inlet of the second channel 24 is connected to the first outlet, and the outlet of the second channel 24 is directed toward the clothing processing chamber 10a.

[0055] In this embodiment, the second channel 24 is used to guide the water in the drain pump 21 to the clothes processing chamber 10a. That is, the water in the clothes processing chamber 10a returns to the clothes processing chamber 10a through the drain channel 22, the drain pump 21 and the second channel 24. Undissolved detergent also returns to the clothes processing chamber 10a with the water. As the inner drum rotates continuously during the clothes processing, the undissolved detergent is fully stirred again and dissolved in the water to clean the clothes and help improve the washing ratio.

[0056] In this embodiment, during the washing process, water in the garment processing chamber 10a enters the drain pump 21 through the drain channel 22. The drain pump 21 continuously pumps water into the first channel 23 and the second channel 24, causing water and undissolved detergent to circulate continuously within the garment processing chamber 10a, the drain channel 22, the first channel 23, and the second channel 24. The rotation of the inner drum and the turbulence effect of the water flowing out of the first channel 23 toward the drain channel 22 make the undissolved detergent more fully dissolved in the water. The dissolved detergent can clean the clothes, thereby helping to improve the washing ratio.

[0057] In some embodiments, the water outlet of the second channel 24 is inclined toward the inside of the clothing processing chamber 10a, so that the water outlet of the second channel 24 sprays water directly into the inside of the clothing processing chamber 10a.

[0058] In some embodiments, such as Figure 1 As shown, the garment processing device includes a door seal ring 30, which is located at the front end of the drum assembly 10, and the water outlet of the second channel 24 is located at the door seal ring 30. In this way, while the second channel 24 discharges water toward the garment processing chamber 10a, it also avoids the need to make holes in the outer drum 11.

[0059] In this embodiment, the position of the water outlet of the second channel 24 is not limited, as long as it is ensured that the water outlet of the second channel 24 can flow towards the clothing processing chamber 10a. The water outlet of the second channel 24 can extend beyond the inner circumferential surface of the door seal ring 30 in a radially inward direction (e.g., Figure 1 As shown), of course, the outlet end of the second channel 24 may also not extend beyond the inner circumference of the door seal ring 30 (as shown). Figure 3 (As shown).

[0060] Understandably, there is no limit to the number of second channels 24; there can be one, two, three, or more.

[0061] In some embodiments, please refer to Figure 2 and Figure 4At least one second channel 24 has its water outlet located above the door seal ring 30 and faces the interior of the garment handling chamber 10a. At this time, undissolved detergent is lifted to a higher position on the drum assembly 10 before falling back down. As the detergent returns from the upper part of the door seal ring 30 to the garment handling chamber 10a, the inner drum rotates, causing the detergent to disperse and foam easily, allowing it to dissolve better in the water and thus improving the washing ratio.

[0062] In other embodiments, the garment handling device includes a door glass bowl, and the outlet of the second channel 24 located above the door seal ring 30 can outlet water toward the door glass bowl. In this embodiment, the water flows along the door glass bowl into the interior of the garment handling chamber 10a.

[0063] It should be noted that the upper part of the door seal ring 30 refers to the part of the door seal ring 30 that is higher than the axis of the cylinder assembly 10.

[0064] In some embodiments, please refer to Figure 2 and Figure 4 At least one water outlet of the second channel 24 is located at the bottom of the inner circumferential surface of the door seal ring 30. In this way, water can flow from the bottom of the door seal ring 30 into the clothing processing chamber 10a.

[0065] In this embodiment, when the drain pump 21 is stopped, the second channel 24 is also used to guide the water accumulated in the door seal ring 30 to the drain pump 21. That is, when the drain pump 21 stops pumping, the water accumulated in the door seal ring 30 can flow to the drain pump 21 through the second channel 24 located at the bottom of the inner circumferential surface of the door seal ring 30, and then be discharged from the garment processing equipment. This facilitates the drainage of water accumulated in the door seal ring 30 and reduces the possibility of bacteria growing in the door seal ring 30.

[0066] In some embodiments, the circulation system includes a main pipe 25 and multiple branch pipes. The inlet of the main pipe 25 is sealed to a first outlet, and the inlets of at least two branch pipes are connected to the main pipe 25. Thus, during the circulation process, water from the drain pump 21 is discharged through the first outlet to the main pipe 25, and then diverted from the main pipe 25 to the branch pipes connected to it. In this example, only one first outlet of the drain pump is required to meet the needs of the circulation system.

[0067] In this embodiment, one of the branch pipes defines a portion of the first channel 23, and at least one branch pipe defines a portion of the second channel 24. That is, among the plurality of branch pipes, one branch pipe leads to the drainage channel 22 and at least one branch pipe leads to the clothing processing chamber 10a.

[0068] For example, in some embodiments, please refer to Figure 2 and Figure 4 There are at least three branch pipes, namely a first branch pipe 26a, a second branch pipe 26b, and a third branch pipe 26c. The inlet ends of the first branch pipe 26a and the second branch pipe 26b are both connected to the main pipe 25. The first branch pipe 26a defines a first channel 23 to discharge water toward the drainage channel 22. The second branch pipe 26b and the third branch pipe 26c define two second channels 24 to discharge water toward the clothing processing chamber 10a. The outlet end of the second branch pipe 26b is located at the upper part of the door seal ring 30 to define the second channel 24 from the upper part of the door seal ring 30 toward the clothing processing chamber 10a. The outlet end of the third branch pipe 26c is located at the bottom of the inner circumferential surface of the door seal ring 30 to define the second channel 24 from the bottom of the inner circumferential surface of the door seal ring 30 toward the clothing processing chamber 10a.

[0069] Understandably, the branch pipes connected to the main pipe 25 can either flow out only toward the garment processing chamber 10a or the drainage channel 22, or continue to divert water through other branch pipes.

[0070] In other embodiments, the drain pump 21 may also have multiple first outlets. For example, in some embodiments, the first branch pipe 26a, the second branch pipe 26b, and the third branch pipe 26c are respectively sealed to their respective first outlets. Alternatively, in other embodiments, two of the three branch pipes are respectively sealed to two first outlets, and the inlet of the remaining branch pipe is connected to an opening on the side wall of one of the first two branch pipes.
