Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a washing machine. Background Technology

[0002] Currently, when people wash clothes, outerwear, underwear, socks, insoles, baby clothes, and other types of clothing are usually washed separately because they are prone to cross-contamination. The washing cycles for outerwear, underwear, socks, and insoles are different. Underwear and socks are best washed daily, while outerwear and insoles are best washed every two weeks. Therefore, it is not advisable to wash different types of clothing together.

[0003] Current fully automatic washing machines are mainly used for washing large items of clothing. When underwear, socks, insoles, and outerwear are washed together, cross-contamination can easily occur. Washing outerwear, underwear, socks, and insoles separately in existing fully automatic washing machines is both wasteful of water and electricity. Washing only outerwear in existing fully automatic washing machines while manually washing smaller items such as underwear, socks, insoles, and baby clothes is very labor-intensive and increasingly unpopular with modern consumers. Therefore, people need a small washing machine specifically designed for washing small items of clothing.

[0004] The applicant's earlier patent application, CN202223033146.5, disclosed an inner liner assembly between the drum and the outer shell for mounting and fixing electrical components, resulting in a more compact structural layout and higher space utilization, suitable for small washing machines. However, existing conventional washing machines often include a detergent dispenser and an automatic dispensing device to meet the need for automatic detergent dispensing. Therefore, how to further fully and rationally utilize the internal space of small washing machines by incorporating a detergent dispenser and automatic dispensing device to improve space utilization has become one of the problems that need to be solved in this field. Utility Model Content

[0005] In view of this, the present invention aims to provide a washing machine that solves the problem in the prior art of how to set up a liquid storage box and an automatic dispensing device in a small washing machine to improve space utilization.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A washing machine includes a shell, an inner liner, a liquid storage device, and a power device. The inner liner is disposed inside the shell and has a liquid storage assembly position and a power assembly position. The liquid storage device is disposed in the liquid storage assembly position, and the power device is disposed in the power assembly position. The power assembly position is located below the liquid storage assembly position. The lower end of the liquid storage device is provided with an outlet pipe and a liquid level sensor. The inlet of the power device is connected to the outlet pipe.

[0008] Furthermore, both the liquid storage device and the power device are detachably connected to the liner.

[0009] Furthermore, an assembly part is provided at the lower end of the liquid storage device, a sealing mounting part is provided at one end of the liquid level sensor, and the other end passes through the assembly part and extends toward the interior of the liquid storage device, with a sealed connection between the sealing mounting part and the assembly part.

[0010] Furthermore, the liquid level sensor is a reed switch type liquid level sensor.

[0011] Furthermore, the liquid storage device includes a main box and a liquid inlet, the liquid inlet being connected to the main box and the main box being connected to the inner liner.

[0012] Furthermore, the liquid storage device includes an extended neck, one end of which is connected to the liquid inlet and the other end of which is connected to the main housing.

[0013] Furthermore, the liquid storage device has an assembly plate on the outer edge of the liquid inlet, and an assembly opening is provided on the upper end face of the liner, with the assembly plate engaging with the assembly opening.

[0014] Furthermore, a support plate is provided inside the assembly port, and the lower surface of the assembly plate abuts against the upper surface of the support plate.

[0015] Furthermore, the washing machine includes a drum, a mixer is provided in the water inlet pipe of the drum, and the outlet of the power unit is connected to the drum and / or connected to the mixer.

[0016] Compared with the prior art, the washing machine described in this utility model has the following advantages:

[0017] The washing machine of this utility model has an outlet pipe located at the lower end of the liquid storage device and a power device located below the liquid storage device. This helps to shorten the distance between the liquid storage device and its corresponding power device, reduce the length of the pipeline, reduce the difficulty of pipeline layout, and reduce the space occupied by the pipeline inside the washing machine. At the same time, under the action of gravity, the detergent tends to flow towards the lower outlet pipe and the power device, so that the power device can easily draw the detergent out of the liquid storage device.

[0018] Meanwhile, due to the requirements of the outlet pipe and pipeline installation, a certain height of space (hereinafter referred to as "necessary space") must be reserved below the liquid storage device. This application further places the liquid level sensor at the lower end of the liquid storage device. While realizing normal liquid level detection of the liquid storage device, the liquid level sensor is also located in the necessary space, making the layout more compact, improving the utilization rate of the necessary space, avoiding the liquid level sensor occupying other non-necessary spaces, and helping to improve the space utilization rate of the entire washing machine.

Detailed Implementation

[0044] The inventive concepts of this disclosure will be described below using terminology commonly used by those skilled in the art to convey the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The directional terms such as "up," "down," "left," "right," "front," and "back" used in this application can be referred to in the appendix. Figure 4 , 7 The coordinate system in the middle; regarding the appendix Figure 8-12 The viewpoints are quite unique, all of which involve rotating the lid and related components up and down to clearly show the corresponding structure.

[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] Example 1

[0048] To address the problem in existing technologies of how to incorporate a liquid storage tank and automatic dispensing device into small washing machines to improve space utilization, this embodiment proposes a washing machine, as shown in the attached figure. Figure 1-17 As shown, the washing machine includes an outer shell (not shown), an inner liner 2, a drum 1, a liquid storage device 3, and a power device 4. The inner liner 2 is disposed between the outer shell and the drum 1. The liquid storage device 3 and the power device 4 are both connected to the inner liner 2. A mixer 5 is installed in the water inlet pipe of the drum 1. The outlet of the liquid storage device 3 is connected to the inlet of the power device 4. The outlet of the power device 4 is directly connected to the drum 1 and / or connected to the mixer 5.

[0049] Therefore, by utilizing the gap between the outer shell and the drum 1, this application places the liquid storage device 3 containing detergent and the power device 4 in this gap, and connects the liquid storage device 3 and the power device 4 to the inner liner 2, thus achieving the purpose of setting up a liquid storage box and an automatic dispensing device in a washing machine (especially a small washing machine). This can make full use of the internal space of the washing machine, improve space utilization, and at the same time ensure the reliable assembly of the liquid storage device 3 and the power device 4, providing a guarantee for the normal operation of the automatic dispensing function of the washing machine.

[0050] Furthermore, with the connection of the power unit 4 and related pipelines, the liquid storage device 3 can be directly connected to the drum 1 and / or connected to the mixer 5 in the water inlet pipeline of the drum 1; under the power of the power unit 4, the detergent stored in the liquid storage device 3 can be directly delivered to the drum 1, or delivered to the mixer 5, mixed with the washing water, and then enter the drum 1 together, so that the small washing machine has at least two automatic dispensing modes, which can meet the dispensing and usage needs of different detergents and help improve the user experience.

[0051] The cylinder 1 includes a liquid inlet section 12, one side of which is connected to the outlet of the power unit 4, and the other side is directly connected to the cylinder 1. This allows the detergent to be delivered directly into the cylinder 1 from the storage device 3, passing sequentially through the power unit 4 and the liquid inlet section 12, without being diluted.

[0052] Preferably, the drum body 1 includes a lid plate 11, and the lid plate 11 is provided with a liquid inlet 12. Since the liquid inlet 12 is provided on the lid plate 11, the liquid inlet 12 will be higher than the washing space (or washing tub) in the drum body 1. The side of the liquid inlet 12 that is directly connected to the drum body 1 can be directly set above the washing space of the drum body 1, so that the detergent can fall directly into the inside of the drum body 1 under the action of gravity after flowing through the liquid inlet 12.

[0053] As attached Figure 15-17As shown, the mixer 5 includes a water inlet pipe 51, a discharge pipe 53, and at least one liquid inlet pipe 52. The water inlet pipe 51 is connected to a water supply unit 7 outside the washing machine, which can be a faucet, water tank, etc., used in daily life. The outlet of the power unit 4 is connected to the liquid inlet pipe 52, and the discharge pipe 53 is directly connected to the drum 1. This allows the detergent to be fully mixed with water inside the mixer 5 before being sent into the drum 1. It should be noted that this application is not limited to the appendix. Figure 15-17 As shown in the structure, the mixer 5 can be equipped with two or more liquid inlet pipes 52. At the same time, the washing machine can also be equipped with a liquid storage box corresponding to the liquid inlet pipe 52 to meet the needs of adding different types of detergents.

[0054] For the installation and fixing of the liquid storage device 3 and the power device 4, the inner liner 2 is provided with a liquid storage assembly position and a power assembly position. The liquid storage device 3 is set in the liquid storage assembly position and the power device 4 is set in the power assembly position. The liquid storage device 3 and the power device 4 are both connected to the inner liner 2 in a detachable manner, preferably by fastener connection.

[0055] The liquid storage device 3 is a liquid storage box, and at least one of them is provided. The power device 4 is a conventional pump for delivering detergent, and at least one of them is provided. This application can provide one liquid storage device 3 and one power device 4. The outlet of the power device 4 is directly connected to the cylinder 1, or the outlet of the power device 4 is connected to the mixer 5, or the outlet of the power device 4 is connected to both the cylinder 1 and the mixer 5.

[0056] As a preferred embodiment, the liquid storage device 3 includes a first liquid storage box 31 and a second liquid storage box 32, and the power device 4 includes a first pump 41 and a second pump 42. The outlet of the first liquid storage box 31 is connected to the inlet of the first pump 41, and the outlet of the first pump 41 is directly connected to the cylinder 1 or to the mixer 5. The outlet of the second liquid storage box 32 is connected to the inlet of the second pump 42, and the outlet of the second pump 42 is directly connected to the cylinder 1 or to the mixer 5. Alternatively, the outlets of the first pump 41 and the second pump 42 can both be connected to the liquid inlet section 12; or, the mixer 5 has two liquid inlet pipes 52, and the outlets of the first pump 41 and the second pump 42 are respectively connected to the corresponding liquid inlet pipes 52; or, one of the outlets of the first pump 41 and the second pump 42 is connected to the liquid inlet section 12, and the other is connected to the liquid inlet pipe 52 of the mixer 5. By setting up two liquid storage boxes and corresponding automatic dispensing components, on the one hand, more detergent can be stored in the limited internal space of the washing machine, which helps to make full use of the internal space of the washing machine and improve space utilization. On the other hand, the washing machine can store different types of detergents and simultaneously realize the independent automatic dispensing of different liquid storage boxes to meet the user's needs for different detergents.

[0057] Correspondingly, the first liquid storage box 31, the second liquid storage box 32, the first pump 41, and the second pump 42 are all connected to the inner liner 2. The inner liner 2 is provided with a first assembly position 21, a second assembly position 22, a third assembly position 23, and a fourth assembly position 24. The first assembly position 21 and the third assembly position 23 are liquid storage assembly positions, and the second assembly position 22 and the fourth assembly position 24 are power assembly positions. The first liquid storage box 31 is disposed in the first assembly position 21, the first pump 41 is disposed in the second assembly position 22, the second liquid storage box 32 is disposed in the third assembly position 23, and the second pump 42 is disposed in the fourth assembly position 24. This ensures that the first liquid storage box 31, the second liquid storage box 32, the first pump 41, and the second pump 42 can be reliably disposed in the gap between the outer shell and the cylinder 1.

[0058] It should be noted that the washing agent used in this application can be a conventional detergent, fabric softener, etc., or it can be a garment treatment agent with other special formulations. The remaining solutions in this embodiment can adopt the technical solutions of at least any one of the other embodiments.

[0059] Example 2

[0060] After the detergent is directly added to the drum 1 through the liquid inlet 12, a small amount of detergent will often remain in the liquid inlet 12. Over time, this will cause the liquid inlet 12 to become blocked and will also breed microorganisms, affecting the normal use of the washing machine.

[0061] To avoid residue of detergent in the liquid inlet section 12, as shown in the attached... Figure 8-14 As shown, the cylinder 1 is provided with a liquid inlet section 12, which includes a first liquid inlet pipe 121, a second liquid inlet pipe 122, a liquid flow channel 13, and a partition structure. The partition structure divides the liquid flow channel 13 into a first channel 131 and a second channel 132. The first liquid inlet pipe 121 is connected to the first channel 131, and the second liquid inlet pipe 122 is connected to the second channel 132. The partition structure has a water passage slit 603, through which the first channel 131 and the second channel 132 can be connected.

[0062] Of the two inlet pipes, one of the first inlet pipe 121 and the second inlet pipe 122 is connected to the external water supply unit 7 for supplying water to the cylinder 1, and the other is connected to the liquid storage device 3 for directly delivering detergent into the cylinder 1. This application does not specifically limit which inlet pipe is for water and which is for detergent. For ease of description, the first inlet pipe 121 and the first channel 131 are used for water intake, and the second inlet pipe 122 and the second channel 132 are used for detergent intake, but this application is not limited to this limitation.

[0063] By setting a water passage 603 in the partition structure, the first channel 131 and the second channel 132 can be connected. After the detergent is added into the cylinder 1 through the second liquid inlet pipe 122 and the second channel 132, water can be introduced into the cylinder 1 through the first liquid inlet pipe 121 and the first channel 131. Some water will flow from the first channel 131 into the second channel 132 along the water passage 603 to rinse any detergent residue that may remain in the liquid inlet section 12. This can effectively prevent detergent residue in the liquid inlet section 12 and avoid blockage of the liquid inlet section 12 and microbial growth.

[0064] The baffle structure can simply be the first baffle 14 installed in the liquid flow channel 13, with the water passage 603 being a notch created in the first baffle 14. While its structure is relatively simple, creating a notch in the first baffle 14 itself inevitably reduces its mechanical properties, which is detrimental to its service life under relatively rapid water flow impact. Therefore, creating a water passage 603 in the first baffle 14 in the liquid flow channel 13 is an alternative solution in this application.

[0065] As a preferred embodiment of this application, the cylinder 1 is provided with a dispensing clip 6, which engages with the liquid inlet 12. A first partition 14 is provided in the liquid flow channel 13, and a water passage 603 is formed between the dispensing clip 6 and the first partition 14. The first channel 131 and the second channel 132 can be connected through the water passage 603. Thus, by providing the dispensing clip 6, a water passage 603 is formed between the dispensing clip 6 and the first partition 14. This solves the problem of detergent residue in the liquid inlet 12 without damaging the structure of the first partition 14, which helps to protect the mechanical properties of the first partition 14 and even the liquid inlet 12, and improves their service life.

[0066] The dispensing clip 6 is equipped with a second partition 61, which is interlocked with the first partition 14, forming a water passage 603 between them. Correspondingly, both the first partition 14 and the second partition 61 can be considered as partition structures separating the liquid flow channel 13. After the dispensing clip 6 is interlocked with the liquid inlet 12, the dispensing clip 6 and the liquid inlet 12 form a dispensing port communicating with the interior of the cylinder 1. The dispensing port is divided by the second partition 61 to form a first liquid outlet 601 and a second liquid outlet 602. The inlet of the first channel 131 is connected to the first liquid inlet pipe 121, and the outlet of the first channel 131 is connected to the first liquid outlet 601. The inlet of the second channel 132 is connected to the second liquid inlet pipe 122, and the outlet of the second channel 132 is connected to the second liquid outlet 602.

[0067] To improve the assembly reliability between the dispensing clip 6 and the liquid inlet 12, a locking block 141 is provided at one end of the first partition 14 facing the dispensing clip 6. The locking block 141 forms a first engagement port 142 with the upper surface of the liquid flow channel 13 (corresponding to the top plate 112 of the barrel cover 11). A protrusion 611 is provided at one end of the second partition 61 facing the first partition 14. A locking plate 62 is provided at the upper end of the second partition 61. A second engagement port 612 is formed between the protrusion 611 and the locking plate 62. The locking plate 62 is inserted into the first engagement port 142 and engages with the first engagement port 142. The locking block 141 is inserted into the second engagement port 612 and engages with the second engagement port 612. This makes the second partition 61 and the first partition 14 form a mutually engaging and locking form, which helps to improve the assembly reliability between the dispensing clip 6 and the liquid inlet 12.

[0068] Based on this, the bottom of the groove of the second engagement port 612 is designated as the first plate surface 613, and the end of the snap-fit ​​plate 62 facing the first engagement port 142 is designated as the second plate surface 621. A second gap 6032 is formed between the snap-fit ​​block 141 and the first plate surface 613, and a first gap 6031 is formed between the second plate surface 621 of the snap-fit ​​plate 62 and the bottom of the groove of the first engagement port 142. (Refer to the attached document.) Figure 14 The first gap 6031 and the second gap 6032 together form a water-passing gap 603. Water (red arrow) can flow from the first channel 131 through the first gap 6031 and the second gap 6032 (as indicated by the blue arrow) into the second channel 132. The red and blue arrows indicate the direction of water flow, used only to differentiate the water flow towards the first gap 6031 and the second gap 6032. Accordingly, this design not only improves the assembly reliability between the dispensing card 6 and the liquid inlet 12, but also creates multiple water-passing gaps, allowing water to flow dispersedly into the second channel 132 from multiple gaps, forming multiple rinsing points. This increases the rinsing area provided to the second channel 132, ensuring that the water flow is evenly distributed throughout the space, preventing the water flow from being too concentrated and causing some areas of the second channel 132 to remain unrinsed.

[0069] The liquid inlet 12 is provided with assembly side plates 15 on both sides of the liquid flow channel 13, and the dispensing clip 6 is provided with side wall parts 63 on both sides, and the side wall parts 63 are engaged with the assembly side plates 15.

[0070] The sidewall component 63 includes a first sidewall 631 and a second sidewall 632. The first sidewall 631 is located on the side of the second sidewall 632 away from the liquid flow channel 13. A snap-fit ​​cavity is formed between the first sidewall 631 and the second sidewall 632. The assembly side plate 15 can be inserted into the snap-fit ​​cavity and snap-fit ​​with it. This not only helps to improve the assembly reliability between the dispensing clip 6 and the liquid inlet 12, but also allows the dispensing clip 6 to surround the outside of the liquid flow channel 13. The medium (water, detergent, etc.) can only flow into the cylinder 1 from the first liquid outlet 601 and the second liquid outlet 602, preventing the medium from overflowing from both sides of the liquid flow channel 13.

[0071] This application further provides multiple snap-fit ​​alignment features for the snap-fit ​​connection between the side wall component 63 and the assembly side plate 15. Specifically:

[0072] The assembly side plate 15 is provided with a protrusion 151 on the side facing the liquid channel 13, and the second side wall 632 is provided with a groove 6321 on the side facing the first side wall 631, and the protrusion 151 and the groove 6321 are engaged.

[0073] The upper end of the protrusion 151 (i.e., the end near the top plate 112 of the lid 11) is provided with a snap-fit ​​groove 152, and the second side wall 632 is provided with a snap-fit ​​plate 6323 on the upper side of the groove 6321, and the snap-fit ​​plate 6323 snaps into the snap-fit ​​groove 152.

[0074] The liquid inlet 12 is provided with a connecting plate 18 below the liquid flow channel 13 (i.e., in the direction away from the top plate 112 of the lid 11). One end of the connecting plate 18 is connected to the assembly side plate 15 on one side of the liquid flow channel 13, and the other end of the connecting plate 18 is connected to the assembly side plate 15 on the other side of the liquid flow channel 13. A slot 6322 is provided at the lower end of the second sidewall 632, and the connecting plate 18 is engaged with the slot 6322. In order to improve the mechanical properties of the connecting plate 18 and avoid stress concentration, the side of the connecting plate 18 away from the slot 6322 is connected to the surrounding plate 111 of the lid 11.

[0075] While the connecting plate 18 is being set, a snap-fit ​​space is also formed between the connecting plate 18 and the snap-fit ​​block 141. The protrusion 611 can be inserted into the snap-fit ​​space and snap-fit ​​with the snap-fit ​​space, so that the second partition 61 and the first partition 14 can further engage and snap-fit ​​with each other.

[0076] Therefore, by setting multiple snap-fit ​​alignments between the side wall component 63 and the assembly side plate 15, the assembly reliability between the dispensing clip 6 and the liquid inlet part 12 can be effectively improved.

[0077] Furthermore, the barrel lid 11 is provided with a limiting platform 16, and a limiting opening 17 is formed between the assembly side plate 15 and the limiting platform 16. The dispensing clip 6 is provided with a limiting foot 64, which can be inserted into the limiting opening 17 and engaged with it. Thus, after the dispensing clip 6 and the liquid inlet 12 are assembled through multiple engagements, the limiting platform 16 on the barrel lid 11 further limits the limiting foot 64 of the dispensing clip 6 within the limiting opening 17, further improving the assembly reliability of the dispensing clip 6.

[0078] Regarding the snap-fit ​​assembly structure between the dispensing clip 6 and the liquid inlet 12, this embodiment proposes multiple snap-fit ​​structures to fully ensure the reliable assembly of the dispensing clip 6 on the barrel cover 11 and to prevent the dispensing clip 6 from loosening due to water flow impact or other special circumstances.

[0079] A support block 65 is provided on the upper surface of the dispensing card 6 (i.e., the side near the top plate 112 of the barrel cover 11). On the one hand, this allows the upper surface of the dispensing card 6 to abut against the top plate 112 more stably, ensuring the reliable assembly of the dispensing card 6 on the barrel cover 11. On the other hand, a sealing element can be further provided at the support block 65 to improve the sealing between the dispensing card 6 and the top plate 112, so that the medium in the liquid flow channel 13 can only enter the cylinder 1 through the first liquid outlet 601 and the second liquid outlet 602, preventing it from overflowing between the dispensing card 6 and the top plate 112.

[0080] The remaining solutions in this embodiment can adopt the technical solutions of at least one of the other embodiments.

[0081] Example 3

[0082] In the process of mixing detergent and water in mixer 5, in order to improve the mixing efficiency of mixer 5, as shown in the attached... Figure 15-17 As shown, the mixer 5 includes a main shell 50 and a sealing cover 56. One end of the main shell 50 is open, and the interior of the main shell 50 has a mixing chamber 54. The mixing chamber 54 is connected to the water inlet pipe 51, the liquid inlet pipe 52, and the discharge pipe 53 respectively. The sealing cover 56 is snapped and sealed to the open end of the main shell 50. A mixing component 561 is provided on the side of the sealing cover 56 facing the mixing chamber 54.

[0083] By integrating the sealing cover 56 with the main housing 50, and making the sealing cover 56 function both sealing and mixing, the sealing performance of the mixer 5 is ensured, preventing water and detergent from leaking out. Furthermore, after water and detergent enter the mixing chamber 54, the mixing efficiency of the detergent and water is effectively improved by the turbulence effect of the mixing component 561 of the sealing cover 56. Simultaneously, the integration of component functions reduces the number of parts, which not only simplifies the structural setup and assembly, reducing structural complexity and assembly difficulty, but also minimizes unnecessary space occupation, improving the space utilization of the washing machine. This makes the structure of this application more suitable for small washing machines.

[0084] The mixing component 561 consists of multiple turbulence columns that extend from the sealing cover 56 to the bottom wall of the main shell 50 (i.e., the end of the main shell 50 away from the open end). After the water and detergent enter the mixing chamber 54, the turbulence of the medium in the mixing chamber 54 is increased under the action of the multiple turbulence columns, which helps to improve the mixing efficiency of the detergent and water.

[0085] For the snap-fit ​​seal between the sealing cap 56 and the open end of the main shell 50, the sealing cap 56 is inserted into the open end of the main shell 50. A mounting flange 562 is provided on the side of the sealing cap 56 away from the mixing chamber 54. The sealing cap 56 is snapped against the side wall of the open end of the main shell 50 through the mounting flange 562. Thus, the sealing cap 56 first acts as a plug-like insertion into the open end of the main shell 50 for a first-level seal. Then, the mounting flange 562 snaps against the side wall of the open end of the main shell 50, covering the entire open end of the main shell 50 for a second-level seal. This effectively improves the assembly reliability and sealing performance between the sealing cap 56 and the main shell 50, preventing water and detergent leakage from the mixer 5. Preferably, the portion of the sealing cap 56 inserted into the open end of the main shell 50 has an interference fit with the inner wall of the main shell 50 to further improve the sealing performance.

[0086] As a preferred embodiment of this application, the water inlet pipe 51 and the outlet pipe 53 are respectively connected to the side wall of the main shell 50, and the liquid inlet pipe 52 is connected to the bottom wall of the main shell 50 (i.e., the end of the main shell 50 away from the open end). Thus, the detergent enters the mixing chamber 54 from the liquid inlet pipe 52 along the axial direction of the turbulence column, while water enters the mixing chamber 54 from the water inlet pipe 51 along the radial direction of the turbulence column. The detergent and water form a cross-flow pattern in the mixing chamber 54, which helps to further improve the mixing efficiency of the detergent and water. At the same time, a large amount of water will also thoroughly flush the outer circumferential surface of the turbulence column, preventing detergent residue in the mixing chamber 54.

[0087] The mixer 5 includes a one-way valve 55, which is disposed in the inlet pipe 52 or on the side of the mixing chamber 54 near the inlet pipe 52, ensuring that the detergent can only enter the mixing chamber 54 from the inlet pipe 52. The connection between the inlet pipe 52 and the bottom wall of the main housing 50 provides sufficient assembly space for the one-way valve 55. Furthermore, the one-way valve 55 prevents water from flowing back from the mixing chamber 54 into the inlet pipe 52 and the pipelines and equipment connected to the inlet pipe 52, thus avoiding unnecessary contamination of the detergent.

[0088] The remaining solutions in this embodiment can adopt the technical solutions of at least one of the other embodiments.

[0089] Example 4

[0090] For conventional washing machines with liquid storage tanks and automatic dispensing devices, a liquid level sensor is usually installed in the liquid storage tank, and this application is no exception. However, while installing the liquid level sensor, this application focuses on how to optimize the layout of the liquid level sensor and related components as much as possible to improve the space utilization of the washing machine.

[0091] As attached Figure 1-7 and appendix Figure 18-22 As shown, the inner liner 2 is provided with a liquid storage assembly position and a power assembly position. The liquid storage device 3 is installed in the liquid storage assembly position, and the power device 4 is installed in the power assembly position. Both the liquid storage device 3 and the power device 4 are detachably connected to the inner liner 2. It should be noted that... Figure 18-21 The liquid storage device 3 in the embodiment is represented by the view of the first liquid storage box 31, and the power device 4 is represented by the view of the first pump 41. However, it is not limited to the first liquid storage box 31 and the first pump 41. The technical content in this embodiment is also applicable to the second liquid storage box 32 and the second pump 42.

[0092] The power assembly position is located below the liquid storage assembly position. Correspondingly, the power unit 4 is also located below the liquid storage device 3, and the lower end of the liquid storage device 3 is provided with an outlet pipe 34. Positioning the outlet pipe 34 at the lower end of the liquid storage device 3 and the power unit 4 below it helps to shorten the distance between the liquid storage device 3 and its corresponding power unit 4, reducing pipeline length, simplifying pipeline layout, and minimizing the space occupied by the pipeline inside the washing machine. Simultaneously, under the influence of gravity, the detergent tends to flow downwards towards the outlet pipe 34 and the power unit 4, allowing the power unit 4 to easily extract the detergent from the liquid storage device 3.

[0093] Based on this, due to the setting of the outlet pipe 34 and the need for pipeline installation, a certain height of space (hereinafter referred to as "necessary space") must be reserved below the liquid storage device 3. In this embodiment, the liquid level sensor 33 is also set at the lower end of the liquid storage device 3. While realizing normal liquid level detection of the liquid storage device 3, the liquid level sensor 33 is also located in the necessary space, making the layout more compact, improving the utilization rate of the necessary space, avoiding the occupation of other non-necessary space by the liquid level sensor 33, and helping to improve the space utilization rate of the entire washing machine.

[0094] For the installation of the liquid level sensor 33, an assembly part 361 is provided at the lower end of the liquid storage device 3. A sealing mounting part 331 is provided at one end of the liquid level sensor 33, and the other end (i.e., the detection end) extends through the assembly part 361 and toward the interior of the liquid storage device 3. The sealing mounting part 331 and the assembly part 361 are sealed together. This ensures the airtightness between the liquid level sensor 33 and the liquid storage device 3 while simultaneously installing the liquid level sensor 33 at the lower end of the liquid storage device 3, preventing detergent leakage from the assembly part 361 of the liquid storage device 3. Preferably, the sealing mounting part 331 and the assembly part 361 are connected by fasteners, and a sealing ring is provided between the sealing mounting part 331 and the assembly part 361.

[0095] The liquid level sensor 33 is preferably a reed switch type liquid level sensor. Since the gap between the outer shell and the cylinder 1 is often relatively narrow, the thickness of the liquid storage device 3 must also be relatively narrow. The reed switch type liquid level sensor has a small diameter and can be installed in the liquid storage device 3 with a small thickness. It can not only provide normal liquid level detection function, but also does not occupy too much space, which helps to miniaturize the washing machine and related components.

[0096] For a single liquid storage device 3, it includes a main box 36 and a liquid inlet 39. The liquid inlet 39 is connected to the main box 36, and the main box 36 is connected to the inner liner 2. The main box 36 is the main container for holding detergent. The spatial shape of the main box 36 is not limited to the spatial shapes of the first liquid storage box 31 and the second liquid storage box 32 shown in the accompanying drawings of this application. It is recommended to determine the shape based on the spatial shape of the gap between the outer shell and the cylinder 1 without causing spatial interference.

[0097] The main housing 36 and the inner liner 2 are connected by fasteners. The outer wall of the main housing 36 is provided with a mounting plate 35, and the inner liner 2 is provided with an assembly column. Fasteners can be inserted into the mounting plate 35 and the assembly column. The mounting plate 35 has a hole structure, and the assembly column has threaded holes to facilitate the installation of fasteners.

[0098] Since the spatial shape of the gap between the outer shell and the drum 1 varies among different washing machines, in order to ensure that the liquid inlet 39 of the liquid storage device 3 is aligned with the detergent filling port of the washing machine, each liquid storage device 3 also includes an extension neck 37. One end of the extension neck 37 is connected to the liquid inlet 39, and the other end is connected to the main box 36. The extension neck 37 can be a tubular component that occupies a small space. This application does not limit its specific spatial shape. The extension neck 37 can even be a flexible tube. Thus, when there is a certain misalignment or narrow space between the installation position of the main box 36 and the position of the liquid inlet 39, the extension neck 37 connects the liquid inlet 39 and the main box 36, ensuring the connection between the liquid inlet 39 and the main box 36 while making full and reasonable use of the gap between the outer shell and the drum 1.

[0099] The liquid storage device 3 has an assembly plate 38 on the outer edge of the liquid inlet 39, and the upper end face 25 of the inner liner 2 has an assembly port 26. The assembly plate 38 is engaged with the assembly port 26, so that while the main body 36 of the liquid storage device 3 is connected to the inner liner 2, the position of the liquid inlet 39 of the liquid storage device 3 is further engaged with the inner liner 2, which can effectively ensure the stability of the assembly of the liquid storage device 3 and prevent unnecessary displacement of the liquid inlet 39.

[0100] A support plate 27 is provided on the inner side of the assembly port 26. The lower surface of the assembly plate 38 abuts against the upper surface of the support plate 27, so that the assembly plate 38 is supported by the support plate 27 and is snapped in the assembly port 26. On the one hand, this creates multiple contact points between the liner 2 and the liquid storage device 3 to disperse the detergent acting on the liner 2 and the gravity of the liquid storage device 3, which helps to ensure the mechanical strength of the liner 2 and avoid stress concentration in the liner 2. On the other hand, it also helps to further improve the reliability of the assembly of the liquid storage device 3.

[0101] The remaining solutions in this embodiment can adopt the technical solutions of at least one of the other embodiments.

[0102] Example 5

[0103] As attached Figure 3-7 As shown, this embodiment proposes a washing machine with a drying function.

[0104] The washing machine includes a drying assembly 8, which is located at the rear of the drum 1 and connected to the drum 1. A liquid storage device 3 is located on the left and / or right side of the drying assembly 8, and a power unit 4 is located on the left and / or right side of the drying assembly 8. Therefore, for washing machines with a drying function, after installing the drying assembly 8 at the rear of the drum 1, a large gap often remains between the rear of the drum 1 and the outer casing. By placing the liquid storage device 3 and the power unit 4 near the drying assembly 8, this gap can be fully utilized to maximize the volume of the liquid storage device 3, allowing more detergent to be stored within the limited internal space of the washing machine, thus improving space utilization.

[0105] For a single liquid storage device 3 and its corresponding power device 4, it can be set on the left or right side of the drying assembly 8. It is preferable to set the liquid storage device 3 and its corresponding power device 4 on the same side of the drying assembly 8. This helps to shorten the distance between the liquid storage device 3 and its corresponding power device 4, reduce the length of the pipeline, reduce the difficulty of pipeline layout, and also reduce the space occupied by the pipeline inside the washing machine.

[0106] As a preferred embodiment, the liquid storage device 3 includes a first liquid storage box 31 and a second liquid storage box 32, and the power device 4 includes a first pump 41 and a second pump 42. The first liquid storage box 31 and the first pump 41 are both located on the left side of the drying assembly 8, and the second liquid storage box 32 and the second pump 42 are both located on the left side of the drying assembly 8. Correspondingly, the first assembly position 21 and the second assembly position 22 are located on the left rear side of the inner liner 2, and the third assembly position 23 and the fourth assembly position 24 are located on the right rear side of the inner liner 2. This arrangement not only makes full use of the gap between the rear side of the drum 1 and the outer shell, increasing the space for storing detergent, thus accommodating more detergent in the limited internal space of the washing machine and improving space utilization, but also distributes the weight of the detergent and the liquid storage device 3 on the left and right sides of the washing machine, providing not only lateral balance but also a certain counterweight effect.
