Description

Technical Field

[0001] This application relates to the field of fabric cleaning, and in particular to a washing machine. Background Technology

[0002] After the fabric is manufactured, it needs to be washed to remove as many chemicals as possible that were present on the surface or inside during the weaving process, reduce the pungent smell of the fabric, and dry it after washing, which also helps to improve the feel of the fabric.

[0003] For example, in the existing fabric washing machine with announcement number CN207793610U, the fabric is fed into the washing tank and immersed below the surface of the cleaning liquid. The stirring rod rotates and contacts the surface of the fabric to clean it. Then the fabric is sent out of the washing tank and vibrated and squeezed to achieve the purpose of dehydration. Finally, the fabric is dried by infrared heating.

[0004] Regarding the aforementioned technologies, during the washing process, many short fiber ends adhering to the fabric surface will float on the surface of the washing liquid. When the fabric is discharged from the washing liquid, some of the fiber ends will still adhere to the fabric surface and be discharged together, resulting in insufficient cleaning of the fabric surface. Summary of the Invention

[0005] To more thoroughly clean the fabric surface, this application provides a washing machine.

[0006] The washing machine provided in this application adopts the following technical solution.

[0007] A washing machine includes a washing tank for feeding fabric into for washing, a dehydration chamber for dehydrating the washed fabric, and a drying chamber for drying the dehydrated fabric. The washing tank is provided with a tank partition that divides the washing liquid into two parts. The tank partition has a through-hole for the fabric to pass through. An inlet roller that presses the fabric into the washing liquid and an outlet roller that drives the fabric out of the washing tank are rotatably connected in the washing tank. The tank partition is located between the inlet roller and the outlet roller. An inlet pipe for feeding the washing liquid is connected to the washing tank near the outlet roller, and an outlet pipe for discharging the washing liquid is connected to the washing tank near the inlet roller.

[0008] By adopting the above technical solution, the lint and some impurities are located in the cleaning liquid near the inlet roller of the tank baffle. This makes it less likely for a lot of lint to adhere to the fabric when it is conveyed to the side of the tank baffle near the outlet roller. Furthermore, the positions of the inlet and outlet pipes ensure that the flow direction of the cleaning liquid through the fabric opening is opposite to the fabric conveying direction, making it less likely for lint to move through the fabric opening to the position of the tank baffle facing the outlet roller. This makes it even less likely for lint to adhere to the surface of the fabric when it is sent out of the washing tank, thus achieving a more thorough cleaning effect on the fabric surface.

[0009] Optionally, the drying chamber is provided with a cleaning frame for the fabric to pass through. The inner circle of the cleaning frame is connected to four brush belts that correspond to the four sides of the fabric. The cleaning frame is located above the liquid surface in the washing tank and on the side of the tank partition near the inlet roller.

[0010] By adopting the above technical solution, the brush belt can remove impurities or stains with strong adhesion to the fabric surface, thereby improving the cleaning effect of the fabric surface.

[0011] Optionally, the washing tank is equipped with two sets of rotating pressure rollers, with the fabric pressed tightly through the two pressure rollers in the same set, and the cleaning frame is located between the two sets of pressure rollers.

[0012] By adopting the above technical solution, a portion of the cleaning liquid in the fabric can be squeezed out, so that the cleaning liquid with more impurities absorbed by the fabric after being brushed can be squeezed out, and then the fabric enters the washing pool to absorb relatively clean cleaning liquid.

[0013] Optionally, the pressure applied to the fabric by one set of pressure rollers located in front of the cleaning frame in the direction of fabric transmission is less than the pressure applied to the fabric by the other set of pressure rollers.

[0014] By adopting the above technical solution, some of the cleaning liquid in the fabric can be squeezed out before the fabric is brushed by the brush belt, so that the brush belt can effectively brush the fabric with a certain amount of cleaning liquid inside, and it is less likely to damage the fabric surface. After the fabric is brushed, the pressure roller squeezes out the cleaning liquid in the fabric to improve the thoroughness of the fabric cleaning.

[0015] Optionally, a group of pressure rollers located behind the cleaning frame in the direction of fabric transmission are formed with several liquid suction holes on their surfaces, and the pressure rollers with liquid suction holes are connected to a liquid suction pipe that creates a negative pressure at the liquid suction holes.

[0016] By adopting the above technical solution, when a set of pressure rollers with high pressure squeezes the cleaning liquid out of the fabric, the suction hole can simultaneously suck in the squeezed cleaning liquid. This makes it less likely for the fabric in the cleaning liquid that moves down into the washing tank after passing through the pressure rollers to absorb the cleaning liquid squeezed out by the pressure rollers. This allows the fabric to effectively remove the cleaning liquid with more internal impurities, which helps to improve the cleanliness of the fabric.

[0017] Optionally, both the outlet pipe and the inlet pipe are connected to a three-way valve, and a return pump is connected between the two three-way valves. The outlet of the return pump can be connected to the inlet pipe, and a collection box is connected to the inlet of the return pump. The collection box is equipped with a filter screen that divides the inside of the collection box into two spaces. The positions of the outlet pipe and the return pump connected to the collection box are located on opposite sides of the filter screen.

[0018] By adopting the above technical solution, when the cleaning solution is relatively clean, the two three-way valves enable the return pump to continuously circulate the cleaning solution in the washing tank, so as to maintain the flow of the cleaning solution at the fabric outlet while reducing the consumption of the cleaning solution. At the same time, it can also collect the thread ends in the cleaning solution near the inlet roller of the tank baffle as much as possible into the collection box for collection, so as to prevent the thread ends from entering the cleaning solution near the outlet roller of the tank baffle. When there are more impurities in the cleaning solution, the two three-way valves switch so that the new cleaning solution in the washing tank is sent in through the inlet pipe, and the dirtier cleaning solution is sent out through the outlet pipe.

[0019] Optionally, the pool partition is slidably connected to two sets of two adjustment gates on the side near the feed roller. The two sets of adjustment gates are slidably connected to each other, and the two sets of adjustment gates form an adjustment opening that faces the fabric passage for the fabric to pass through.

[0020] By adopting the above technical solution, after the specifications of the fabric are adjusted to a certain extent, the two sets of adjustment gates can also be adjusted accordingly to fit the fabric, so that the cleaning liquid near the position of the adjustment gate can maintain a faster flow rate.

[0021] Optionally, each of the two regulating gates in the same group is fixedly connected with a lever whose top end is located above the liquid surface in the washing pool. The two levers in the same group are threaded together with an adjusting screw that moves the two regulating gates in the same group closer or further apart. The pool partition is equipped with a screw motor that rotates the adjusting screw. A distance sensor is provided between the two levers in the same group, located above the cleaning liquid surface in the washing pool, and used to detect the distance between the two regulating gates in the same group.

[0022] By adopting the above technical solution, the two regulating gates in the same group can move synchronously, and the distance sensor is not easily affected by lint or other impurities in the cleaning fluid, so that the spacing adjustment between the regulating gates is not easily affected, and a more suitable spacing can be maintained between the regulating gates and the fabric.

[0023] Optionally, the dehydration chamber is provided with a slope block whose lowest point is located directly above the liquid surface of the washing tank, and a set of two squeeze rollers are rotatably connected directly above the slope block, clamping the fabric so that the washing liquid flows down to the slope block.

[0024] By adopting the above technical solution, the fabric entering the dewatering chamber can first squeeze the cleaning liquid onto the slope block and flow into the washing tank, thereby reducing the consumption of cleaning liquid in the washing tank.

[0025] Optionally, the dehydration chamber is equipped with a clean water tank for the fabric to enter and wash away the cleaning liquid. The dehydration chamber is rotatably connected to a row of dehydration rollers that are pressed tightly against the fabric. The row of dehydration rollers is used to drive the fabric in an S-shape. The dehydration rollers are located directly above the clean water tank.

[0026] By adopting the above technical solution, the fabric is cleaned to remove residual cleaning liquid inside, and then the water in the fabric is squeezed out by the dewatering roller and falls back into the clean water pool.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. When the fabric is conveyed to the side of the tank partition near the outlet roller, it is less likely to have many loose threads attached to it. In addition, the position of the inlet and outlet pipes makes the flow direction of the cleaning liquid through the fabric opening opposite to the direction of fabric conveying, which makes it even less likely for loose threads to adhere to the surface of the fabric when it is sent out of the washing tank, so as to achieve a more thorough cleaning effect on the surface of the fabric.

[0029] 2. After the fabric specifications are adjusted, the two sets of adjustment gates can also be adjusted accordingly to fit the fabric, so that the cleaning fluid near the adjustment gate position can maintain a faster flow rate. Attached Figure Description

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses a washing machine, referring to... Figure 1It includes a washing tank 1 with internal cleaning liquid, the fabric is fed into the washing tank 1 from one end along its length, the washing tank 1 has a dehydration chamber 2 on the side for feeding the fabric out, which removes the cleaning liquid from the washed fabric as much as possible, the dehydration chamber 2 has a drying chamber 3 on the side for feeding the fabric out, and the drying chamber 3 dries the dehydrated fabric through hot air convection.

[0036] Reference Figure 1 and Figure 2 Inside the washing tank 1, an inlet roller 51 and an outlet roller 52 are rotatably connected below the liquid surface. The axes of the inlet roller 51 and the outlet roller 52 are aligned with the width of the washing tank 1. Fabric is fed into the washing tank 1 and driven below the liquid surface by the inlet roller 51. After passing through the outlet roller 52, the fabric is discharged from the washing tank 1. A vertical tank partition 4 is fixedly connected inside the washing tank 1. The length of the partition 4 is aligned with the width of the washing tank 1, and the upper surface of the partition 4 is higher than the liquid surface in the washing tank 1. A fabric passage opening 5 is provided through the partition 4, located below the liquid surface. The length of the fabric passage opening 5 is aligned with the length of the partition 4, and the opening area of ​​the fabric passage opening 5 is relatively large to accommodate the largest fabric sizes. The fabric passes horizontally through the fabric passage opening 5, preventing loose threads floating on the liquid surface on the side of the partition 4 facing the inlet roller 51 from adhering to the fabric surface after the fabric is discharged from the washing tank 1.

[0037] Reference Figure 1 Two sets of two pressure rollers 57 are rotatably connected above the liquid surface of the washing tank 1. The axis of the pressure rollers 57 is aligned with the width of the washing tank 1. The fabric in the washing tank 1 is horizontally driven between the two sets of pressure rollers 57. A cleaning frame 55 is fixedly connected between the two sets of pressure rollers 57. Four brush belts 56 are driven within the cleaning frame 55. The brush belts 56 are driven by steel rollers and a motor installed inside the cleaning frame 55. Each brush belt 56 corresponds to one surface of the fabric, so that strongly adhesive impurities or stains on the fabric can be brushed away. The set of pressure rollers 57 close to the feed roller 51 that feeds the fabric into the cleaning frame 55 can squeeze out some of the cleaning liquid from the fabric, so that the brush belts 56 can thoroughly brush the fabric and also prevent the fabric surface from being greatly damaged by the brush belts 56. A set of pressure rollers 57, located away from the feed roller 51 and squeezing the fabric sent out of the cleaning frame 55, can squeeze out all the cleaning liquid from the fabric. The surface of the set of pressure rollers 57, located away from the feed roller 51, is evenly provided with suction holes 58. A suction pipe 59 is fixedly connected to the outside of the washing tank 1 and is connected to the pressure rollers 57 with suction holes 58. The suction pipe 59 is connected to an external diaphragm pump so that the cleaning liquid squeezed out by the pressure rollers 57 can be sucked in by the suction holes 58 and discharged to the outside of the washing tank 1, so that the cleaning liquid that has been completely squeezed out is not easily absorbed by the fabric that moves down into the washing tank 1.

[0038] Reference Figure 2The washing tank 1 is equipped with an inlet pipe 53 connected to one end of the side roller 52, which pumps in the mixed cleaning solution. The washing tank 1 is also equipped with an outlet pipe 54 connected to one end of the side roller 51, which discharges the cleaning solution from the washing tank 1 after a certain period of use. This ensures that the flow direction of the cleaning solution at the fabric opening 5 is opposite to the direction of fabric movement at the fabric opening 5, preventing lint and impurities in the cleaning solution on the side of the tank partition 4 facing the side roller 51 from flowing into the cleaning solution on the side of the tank partition 4 facing the side roller 52. Both the inlet pipe 53 and the outlet pipe 54 are equipped with three-way valves 48 near the washing tank 1. A collection tank 46 and a return pump 45 connect the two three-way valves 48. The cleaning solution in the washing tank 1 is sent to the collection tank 46 via the outlet pipe 54 and then returned to the washing tank 1 via the return pump 45 and the inlet pipe 53. A filter screen 47, which is inclined and can block the wire end from passing through, is fixedly connected inside the collection box 46. The end of the outlet pipe 54 connected to the collection box 46 is lower than the height of the filter screen 47, and the end of the return pump 45 connected to the collection box 46 is higher than the height of the filter screen 47.

[0039] Reference Figure 3 Two sets of two regulating gates 49 are slidably connected to the vertical side of the pool partition 4 near the inlet roller 51. One set of regulating gates 49 is vertical in length and the other set of regulating gates 49 is horizontal in length. The vertical regulating gates 49 move horizontally and the horizontal regulating gates 49 move vertically. An regulating port 31 is formed between the two sets of regulating gates 49, close to each surface of the fabric, so that when fabrics of different specifications pass through the regulating port 31, the flow rate of the cleaning liquid at the regulating port 31 is relatively fast. A vertical regulating gate 49 is inserted into and slidably connected to a horizontal regulating gate 49. Two regulating gates 49 in the same group are fixedly connected to a set of two screw levers 32. The screw levers 32 in the same group are threadedly connected to the same regulating screw 33 above the liquid surface of the washing pool 1. The threads on both sides of the center point of the regulating screw 33 are opposite in direction. The distance between the two screw levers 32 connected to the regulating screw 33 and the center point of the corresponding regulating screw 33 is equal. The regulating screw 33 is rotatably connected to the upper part of the pool partition 4. Two screw motors 34 are fixedly connected to the pool partition 4. The output shafts of the two screw motors 34 are coaxially fixedly connected to the two regulating screws 33.

[0040] Reference Figure 3 Two yarn levers 32 in the same group are fixedly connected to a distance sensor 35 above the liquid surface of the washing tank 1. The distance sensor 35 detects the distance between the two yarn levers 32 by laser ranging, so as to know the distance between the two corresponding adjustment gates 49, so as to adjust the distance between the two adjustment gates 49 in the same group to a suitable position for different specifications of fabric.

[0041] Reference Figure 2A ramp block 41 is fixedly connected to the dewatering chamber 2 near the side where the fabric is fed in. The lowest point of the ramp block 41 is located above the liquid surface in the washing tank 1. Two squeezing rollers 42 are rotatably connected inside the dewatering chamber 2. The squeezing rollers 42 are located directly above the upper part of the ramp block 41. The fabric passes through the two squeezing rollers 42, so that the cleaning liquid in the fabric is squeezed out and flows down onto the ramp block 41 and back into the washing tank 1. A clear water tank 43 is provided inside the dewatering chamber 2. The fabric that has passed through the squeezing rollers 42 enters the clear water tank 43 to wash away the residual cleaning liquid in the fabric. A row of dewatering rollers 44 arranged horizontally is rotatably connected inside the dewatering chamber 2. The fabric fed out of the clear water tank 43 is driven in an S-shape in the row of dewatering rollers 44, so that the residual water in the fabric is squeezed out and falls into the clear water tank 43.

[0042] The principle of a washing machine according to an embodiment of this application is as follows: the fabric is fed into the washing tank 1 and first enters the cleaning liquid to wash away most of the loose threads. Then, after passing through a set of pressure rollers 57 to squeeze out some of the cleaning liquid, the fabric passes through the cleaning frame 55 so that the brush belt 56 can further clean the surface of the fabric. Then, the brush belt 56 passes through the pressure rollers 57 with suction holes 58 to remove as much cleaning liquid as possible from the fabric. Then, the fabric is fed back into the cleaning liquid and passes through the adjustment port 31 and the fabric passage 5 in sequence. Then, the fabric is sent out of the washing tank 1 and passes between two squeezing rollers 42 to squeeze out the cleaning liquid from the fabric. The fabric then enters the clean water tank 43 to wash away the residual cleaning liquid and passes through a row of dewatering rollers 44 to squeeze out the residual water from the fabric. Finally, the fabric enters the drying chamber 3 to complete the drying and then is rolled up.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
