Abstract
Description
Technical Field
[0001] This disclosure relates to the field of household appliance technology, and in particular to a washing machine. Background Technology
[0002] Washing machines are clothing processing devices that convert electrical energy into mechanical energy to wash clothes. They are now commonplace in almost every household.
[0003] Currently, many washing machines are equipped with an automatic detergent dispensing function. This function mainly relies on an electric pump, which draws detergent from the reservoir into the water inlet or directly into the washing machine drum at appropriate times, achieving automatic detergent dispensing. However, the addition of an electric pump increases the cost of the washing machine and adds complexity to its control operation. Utility Model Content
[0004] In view of this, the purpose of this disclosure is to provide a washing machine that improves the technical problems of high cost and complex control operation of washing machines due to the addition of an electric liquid pump in the prior art.
[0005] To achieve at least one of the above objectives, this disclosure provides the following technical solutions:
[0006] In a first aspect, a washing machine is provided, comprising:
[0007] The tank has an inlet, and the interior of the tank is equipped with a water inlet structure, a dispensing box, and a washing drum. The water inlet structure is configured to guide external water into the washing drum through the dispensing box.
[0008] The door cover is movably connected to the housing via a shaft to open or close the inlet.
[0009] Liquid storage box, used to store detergents and care products;
[0010] A press pump, including a press lever, is configured to drive the press pump by applying force to press the press lever to pump the detergent in the reservoir into the dispensing box;
[0011] During the opening or closing of the inlet, the cover and the push rod work together in a coordinated manner. The cover can apply force to the push rod and move it to drive the push pump to work.
[0012] In the above technical solution, by linking the opening and closing of the door cover with the pressing lever, the user will open and close the door cover at least once every time they wash clothes. The movement of the door cover during this process will mechanically squeeze the pressing lever, thereby driving the pressing pump to work and pumping a certain amount of detergent from the storage tank to the dispensing box, thus realizing the automatic detergent dispensing function. Compared with washing machines on the market that use electric liquid pumps to achieve the automatic detergent dispensing function, the washing machine using the above automatic detergent dispensing solution is more cost-effective and easier to operate.
[0013] In some embodiments, the door cover has an outer surface that is positioned away from the inlet when the door cover is rotated about an axis to fully close the inlet;
[0014] During the opening of the inlet, the outer surface of the door can directly or indirectly press the pressing rod and drive it to move, thereby activating the pressing pump.
[0015] In the above technical solution, by linking the outer surface of the door cover with the pressing rod, the detergent is dispensed by squeezing the pressing rod with the outer surface during the opening of the door cover. The fit between the outer surface and the pressing rod can be clearly observed, which is conducive to timely detection and handling of abnormal fit between the outer surface and the pressing rod.
[0016] In some embodiments, a portion of the pump is disposed within the reservoir, and at least a portion of the push rod is exposed outside the reservoir.
[0017] The liquid storage box is located on the top of the box and near the end where the door is movably connected to the box.
[0018] In the above technical solution, by placing the pump and the liquid storage box on the top of the box, it is convenient to disassemble and assemble the pump and the liquid storage box with the box, and it is also convenient to replace and replenish the detergent in the liquid storage box.
[0019] In some embodiments, when the door cover is rotated about the axis to the maximum opening angle, the distance the pressing rod moves during the pressing process is the maximum moving distance, and the amount of detergent that the pressing pump can pump into the dispensing box in a single operation is the maximum pumping amount. The maximum moving distance is positively correlated with the maximum pumping amount.
[0020] The outer surface of the door cover is equipped with height-adjustable adjustment blocks;
[0021] During the opening of the inlet, the door cover presses the push rod by adjusting the block;
[0022] The adjustment block is configured to change the maximum travel distance of the push rod by adjusting the height of the adjustment block, thereby controlling the maximum pumping volume of the push pump.
[0023] In the above technical solution, by setting an adjustable block on the outer surface of the door cover, and the adjustable block and the pressing rod are linked together, the maximum moving distance of the pressing rod can be changed during the pressing process by using the adjustable block at different height positions, thereby controlling the maximum pumping volume of the pressing pump and adjusting the amount of detergent added; moreover, setting the adjustable block on the outer surface of the door cover makes it easier to adjust the adjustable block.
[0024] In some embodiments, the door cover has an inner surface that faces the inlet when the door cover is rotated about an axis to fully close the inlet;
[0025] During the closing of the inlet, the inner surface of the door can directly or indirectly press the push rod and move it to drive the push pump.
[0026] In the above technical solution, by linking the inner surface of the door cover with the pressing rod, the inner surface is used to squeeze the pressing rod to dispense detergent during the closing process of the door cover, which makes it easier to apply force to the door cover and can apply greater pressure to the pressing rod; moreover, the pressing rod can be automatically pressed during the closing and falling process of the door cover by lever principle under its own weight, which saves users more effort.
[0027] In some embodiments, a portion of the pump is disposed within the reservoir, and at least a portion of the push rod is exposed outside the reservoir.
[0028] The liquid storage box is located inside the tank. When the door is fully closed, the liquid storage box is located below the door.
[0029] In the above technical solution, by placing the pump and liquid storage box inside the cabinet and below the door, the washing machine can be made to look more beautiful and neat.
[0030] In some embodiments, when the door cover rotates about the axis to fully close the inlet, the distance the pressing lever moves during the pressing process is the maximum moving distance, and the amount of detergent that the pressing pump can pump into the dispensing box in a single operation is the maximum pumping amount. The maximum moving distance is positively correlated with the maximum pumping amount.
[0031] The inner surface of the door cover is equipped with a height-adjustable adjustment block;
[0032] During the closing of the inlet, the door cover presses the push rod using the adjusting block;
[0033] The adjustment block is configured to change the maximum travel distance of the push rod by adjusting the height of the adjustment block, thereby controlling the maximum pumping volume of the push pump.
[0034] In the above technical solution, by setting an adjustable block on the inner surface of the door cover, and the adjustable block and the pressing rod are linked together, the maximum moving distance of the pressing rod can be changed during the pressing process by using the adjustable block at different height positions, thereby controlling the maximum pumping volume of the pressing pump and adjusting the amount of detergent added; moreover, setting the adjustable block on the inner surface of the door cover can make the appearance of the washing machine more beautiful and neat.
[0035] In some embodiments, there are multiple liquid storage boxes, and different liquid storage boxes are configured to store different detergents;
[0036] The dispensing box is divided into multiple chambers, and each chamber corresponds to a different liquid storage box.
[0037] Each reservoir of detergent can be pumped into a corresponding chamber via a push-button pump.
[0038] In the above technical solution, by setting multiple liquid storage boxes, different detergents can be contained to achieve automatic dispensing of different detergents; moreover, each liquid storage box has a corresponding chamber in the dispensing box. After different detergents are dispensed into different chambers, under the control of the washing machine, the water inlet structure can be connected to different chambers based on different washing stages, so that the corresponding detergents can be flushed into the washing drum by the water inlet.
[0039] In some embodiments, the push pump includes:
[0040] The extrusion chamber includes a temporary storage chamber and a first connecting port, a second connecting port, and a slide chamber connected to the temporary storage chamber.
[0041] The liquid inlet pipe has one end connected to the inner cavity of the liquid storage box and the other end connected to the first connecting port.
[0042] The liquid outlet tube has one end connected to the second connecting port and the other end connected to the inner cavity of the dispensing box.
[0043] The first check valve is located between the inlet pipe and the first connecting port. The first check valve is configured to open the flow channel of the detergent from the inlet pipe to the first connecting port and close the flow channel of the detergent from the first connecting port to the inlet pipe.
[0044] The second check valve is located between the second connecting port and the outlet pipe. The second check valve is configured to open the flow channel of the detergent from the second connecting port to the outlet pipe and close the flow channel of the detergent from the outlet pipe to the second connecting port.
[0045] The pressing rod is partially slidably installed inside the slide cavity;
[0046] An elastic element is disposed between the pressing rod and the cavity wall of the temporary storage cavity along the sliding direction of the pressing rod, and the elastic element is configured to reset the pressing rod;
[0047] In this process, by pressing the pressing rod, the pressing rod slides in the slide cavity toward the temporary storage cavity, squeezing the detergent in the temporary storage cavity, and using the pressure difference between the temporary storage cavity and the outlet pipe to conduct the second check valve, so as to pump the detergent in the temporary storage cavity into the dispensing box through the outlet pipe.
[0048] The elastic element drives the pressing rod to reset, causing the pressing rod to slide away from the temporary storage chamber in the slide cavity. The pressure difference between the temporary storage chamber and the inlet pipe is used to open the first check valve, so that the detergent in the storage box is pumped into the temporary storage chamber through the inlet pipe.
[0049] In the above technical solution, the press pump utilizes the inlet pipe, temporary storage chamber, and outlet pipe, along with the first and second check valves, to form a unidirectional detergent flow channel from the storage box to the dispensing box. The pressure in the temporary storage chamber is changed by the movement of the press rod in the slide chamber, creating a pressure difference between the press pump and the inlet and outlet pipes. This allows the detergent in the storage box to be drawn into the temporary storage chamber and the detergent in the temporary storage chamber to be pumped into the dispensing box. Moreover, the press pump with the above-mentioned structure is simple in design and easy to operate.
[0050] Secondly, a washing machine is also provided, comprising:
[0051] The tank has an inlet, and the interior of the tank is equipped with a water inlet structure, a dispensing box, and a washing drum. The water inlet structure is configured to guide external water into the washing drum through the dispensing box.
[0052] The door cover is movably connected to the housing via a shaft to open or close the inlet.
[0053] Liquid storage box, used to store detergents and care products;
[0054] A press pump, including a press lever, is configured to drive the press pump by applying force to press the press lever to pump the detergent in the reservoir into the dispensing box;
[0055] The door cover is equipped with a height-adjustable adjustment block, and the height position of the adjustment block includes at least a first height position and a second height position.
[0056] When the adjusting block is at the first height position, during the process of opening or closing the inlet of the door cover, the adjusting block and the pressing rod work together. The adjusting block can apply force to the pressing rod and drive the pressing rod to move, so as to drive the pressing pump to work.
[0057] When the adjusting block is in the second height position, neither the door cover nor the adjusting block applies force to the pressing lever during the opening or closing of the inlet.
[0058] In the above technical solution, the opening and closing motion and stroke of the door cover enable the adjusting block and the pressing rod to work together. Since the user opens and closes the door cover at least once each time they wash clothes, the movement of the door cover during this process mechanically squeezes the pressing rod, driving the pump to work and pumping a certain amount of detergent from the storage tank into the dispensing box, thus achieving automatic detergent dispensing. Furthermore, by using the adjusting block at different heights, the maximum movement distance of the pressing rod can be changed during the squeezing process, thereby controlling the maximum pumping volume of the pump and adjusting the amount of detergent dispensed. Additionally, by adjusting the height of the adjusting block, the door cover and the adjusting block can be kept from applying pressure to the pressing rod, thus turning off the automatic dispensing function.

[0089] As part of the inventive concept of this disclosure, before describing the embodiments of this disclosure, it is necessary to analyze the reasons for the high cost and complex control operation of washing machines with automatic detergent dispensing function in related technologies, and obtain the technical solution of the embodiments of this disclosure through reasonable analysis.
[0090] In related technologies, washing machines are clothing processing devices that convert electrical energy into mechanical energy to wash clothes. They are now widely used in households. During the washing and rinsing stages, users need to add detergent to the dispenser each time they wash clothes, or at different stages of the washing process. This is inconvenient for users who wash clothes frequently. Therefore, washing machines with automatic dispensing functions are common on the market. Users no longer need to add a fixed amount of detergent to the dispenser each time; instead, they can add a large amount at once. The automatic dispensing function automatically draws a certain amount of detergent from the reservoir and dispenses it into the washing machine based on the amount of clothes and water used each time. This allows users to replace the detergent only every few weeks or even months, greatly reducing the need for manual detergent addition and the difficulty in accurately calculating and controlling the amount of detergent used. However, implementing the automatic dispensing function requires an electric pump to draw detergent from the reservoir and requires certain initial settings to modify the control program of the washing machine to adjust the amount of detergent used or to turn the automatic dispensing function on and off. The addition of an electric liquid pump makes washing machines with automatic dispensing functions very expensive and their operation very complex, greatly increasing the consumer's financial burden and the complexity of product operation.
[0091] To address this issue, this disclosure provides a washing machine that achieves automatic detergent dispensing through a mechanical means by linking the opening and closing of the door with a pressing lever. This solves the technical problem in the prior art where the addition of an electric liquid pump results in high washing machine costs and complex control operations.
[0092] The technical solutions of the embodiments of this disclosure are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.
[0093] Please refer to the above. Figures 1 to 3 as well as Figure 5 , Figure 1 and Figure 2 A schematic diagram of the internal structure of a washing machine is provided, showing the basic components of the washing machine. Figure 3 A schematic diagram of a washing machine with a liquid storage box is provided; it shows a structural relationship between the liquid storage box and the washing machine. Figure 5 A schematic diagram of the internal structure of a push-pump assembled in a liquid reservoir is provided; it shows a structural relationship between the liquid reservoir and the push-pump.
[0094] An embodiment of this disclosure provides a washing machine, such as Figure 1 and Figure 2As shown, the washing machine includes a cabinet 1, a water inlet structure 2, a detergent dispenser 3, and a washing drum (not shown) disposed within the cabinet 1. The washing drum can hold clothes and can rotate within the cabinet 1 for washing or rinsing. The detergent dispenser 3 is installed in the cabinet 1 by a pull-out mechanism. The inner cavity of the detergent dispenser 3 can hold detergent, which can be a detergent for washing clothes and / or a fabric softener for leaving clothes soft and smooth after washing. The water inlet structure 2 is configured to guide external water into the detergent dispenser 3, allowing the detergent in the dispenser 3 to mix with the incoming water and be flushed into the washing drum to facilitate washing or rinsing of the clothes.
[0095] In this embodiment, as Figure 1 and Figure 2 As shown, the box 1 is usually a rectangular hollow structure with a receiving cavity inside, in which a washing drum is installed; the box 1 is also provided with an inlet 11 that communicates with the receiving cavity, through which clothes can be put into the washing drum and taken out of the washing drum.
[0096] Optionally, the inlet 11 is located at the top of the housing 1 and above the washing drum, which facilitates the loading and unloading of clothes.
[0097] In this embodiment, as Figure 1 and Figure 2 As shown, the washing machine also includes a door cover 4, which is movably connected to the housing 1 via a shaft 43. The door cover 4 is configured to open or close the inlet 11.
[0098] Optionally, the door cover 4 can be in the form of a rectangular plate, a circular plate, etc.
[0099] For example, a specific connection method between the door cover 4 and the box body 1 can be: the rear end of the door cover 4 is hinged to the top rear end of the box body 1 via a shaft 43, and the front end of the door cover 4 can be connected to the top front end of the box body 1 by a snap-fit method. The snap-fit method can be a matching protrusion and a slot. One of the door cover 4 and the box body 1 is provided with a protrusion, and the other is provided with a slot. When the door cover 4 is fully closed at the inlet 11, the protrusion and the slot engage and lock tightly, ensuring the reliability and stability of the connection between the door cover 4 and the box body 1 after the door cover 4 is closed. When it is necessary to open the door cover 4, force can be applied to the door cover 4 to separate the protrusion and the slot, thereby opening the door cover 4.
[0100] In this embodiment, as Figure 3 As shown, the washing machine also includes a liquid storage box 5, which is usually a hollow cuboid structure. It can be used to store detergent and care products. The liquid storage box 5 is also provided with an injection port, through which detergent and care products can be added into the liquid storage box 5 to facilitate the replacement and replenishment of detergent and care products.
[0101] Optionally, the liquid storage box 5 is detachably installed on the housing 1. By removing the liquid storage box 5 from the housing 1, it is convenient to clean, maintain and replace the liquid storage box 5.
[0102] In this embodiment, as Figure 3 and Figure 5 As shown, the washing machine also includes a press pump 6, which includes a press lever 61. The press lever 61 is configured to drive the press pump 6 to work by applying force to press the press lever 61, so as to pump the detergent in the liquid storage box 5 into the dispensing box 3.
[0103] During the opening or closing of the inlet 11, the cover 4 and the push rod 61 work together. The cover 4 can apply force to the push rod 61 and move the push rod 61 to drive the push pump 6 to work.
[0104] It should be noted that the linkage between the door cover 4 and the pressing rod 61 can include the following situations:
[0105] 1. Throughout the entire process of opening the inlet 11, the door cover 4 and the pressing rod 61 are always in a linked cooperation. That is, from the closed state to the fully open state, the door cover 4 continuously applies force to the pressing rod 61 and makes the pressing rod 61 continuously move, so as to drive the pressing pump 6 to work continuously.
[0106] Second, during the initial period of opening the inlet 11, the door cover 4 and the pressing rod 61 do not form a linkage; during the later period of opening the inlet 11, the door cover 4 and the pressing rod 61 form a linkage. When the door cover 4 and the pressing rod 61 form a linkage, the door cover 4 applies force to the pressing rod 61 and moves the pressing rod 61 to drive the pressing pump 6 to start working until the door cover 4 is in a fully open state.
[0107] Third, throughout the entire process of closing the inlet 11, the door cover 4 and the pressing rod 61 are always in a linked cooperation. That is, from the fully open state to the closed state, the door cover 4 continuously applies force to the pressing rod 61 and makes the pressing rod 61 continuously move, so as to drive the pressing pump 6 to work continuously.
[0108] Fourth, during the initial period of closing the inlet 11, the door cover 4 and the pressing rod 61 do not form a linkage; during the later period of closing the inlet 11, the door cover 4 and the pressing rod 61 form a linkage. When the door cover 4 and the pressing rod 61 form a linkage, the door cover 4 applies force to the pressing rod 61 and moves the pressing rod 61 to drive the pressing pump 6 to start working until the door cover 4 is in the closed state.
[0109] In the above technical solution, by linking the opening and closing of the door cover 4 with the pressing rod 61, the user will open and close the door cover 4 at least once every time they wash clothes. During this process, the movement of the door cover 4 will mechanically squeeze the pressing rod 61 to drive the pressing pump 6, thereby pumping a certain amount of detergent from the liquid storage box 5 into the dispensing box 3, thus realizing the automatic dispensing function of detergent. Compared with washing machines on the market that use electric liquid pumps to realize the automatic dispensing function of detergent, the washing machine using the above automatic detergent dispensing solution is more cost-effective and easier to operate.
[0110] Please refer to the above. Figure 5 and Figure 6 , Figure 5 A schematic diagram of the internal structure of a push-pump assembled in a liquid reservoir is provided; it shows a structural relationship between the liquid reservoir and the push-pump. Figure 6 A schematic diagram of a liquid storage box installed above a dispensing box is provided; it shows a structural relationship between the liquid storage box and the dispensing box.
[0111] In some embodiments, such as Figure 5 and Figure 6 As shown, a specific structure of the press pump 6 can be as follows: The press pump 6 includes a squeezing chamber 62, an inlet pipe 63, an outlet pipe 64, a first check valve 65, a second check valve 66, a pressing rod 61, and an elastic element 67. The squeezing chamber 62, the inlet pipe 63, and the outlet pipe 64 are connected and can form a flow channel between the storage box 5 and the dispensing box 3. The first check valve 65 and the second check valve 66 are disposed in this flow channel, making it a unidirectional flow channel. The pressing rod 61, by moving, can create a pressure difference between the squeezing chamber 62 and the inlet pipe 63 and outlet pipe 64. Using this pressure difference and the unidirectional flow channel, the detergent in the storage box 5 can be pumped into the dispensing box 3. The elastic element 67 can reset the pressing rod 61, allowing the press pump 6 to repeatedly pump the detergent.
[0112] In this embodiment, as Figure 5 As shown, the compression chamber 62 includes a temporary storage chamber 621 and a first connecting port 622, a second connecting port 623 and a slide chamber 624 connected to the temporary storage chamber 621.
[0113] The first connecting port 622 can be connected to the inner cavity of the liquid storage box 5 through the liquid inlet pipe 63, so that the detergent in the liquid storage box 5 can flow into the temporary storage cavity 621 through the liquid inlet pipe 63.
[0114] A first check valve 65 is also provided between the inlet pipe 63 and the first connecting port 622. The first check valve 65 is configured to open the flow channel of the detergent from the inlet pipe 63 to the first connecting port 622 and close the flow channel of the detergent from the first connecting port 622 to the inlet pipe 63. That is, the first check valve 65 can allow the detergent in the storage box 5 to flow through the inlet pipe 63 to the temporary storage chamber 621, and can prevent the detergent in the temporary storage chamber 621 from flowing back into the inlet pipe 63.
[0115] The second connecting port 623 can be connected to the interior of the dispensing box 3 through the liquid outlet pipe 64, allowing the detergent in the temporary storage chamber 621 to flow into the dispensing box 3 through the liquid outlet pipe 64.
[0116] A second check valve 66 is also provided between the second connecting port 623 and the outlet pipe 64. The second check valve 66 is configured to open the flow channel of the detergent from the second connecting port 623 to the outlet pipe 64 and close the flow channel of the detergent from the outlet pipe 64 to the second connecting port 623. That is, the second check valve 66 can allow the detergent in the temporary storage chamber 621 to flow into the dispensing box 3 through the outlet pipe 64, and can prevent the detergent in the outlet pipe 64 from flowing back into the temporary storage chamber 621.
[0117] A portion of the pressing rod 61 is exposed outside the compression chamber 62 and is used to form a linkage with the door cover 4, while the other portion of the pressing rod 61 is slidably installed in the slide cavity 624.
[0118] like Figure 5 and Figure 6 As shown, the movement of the pressing rod 61 within the slide cavity 624 includes the following two cases:
[0119] 1. By pressing the pressing lever 61, the pressing lever 61 slides in the slide cavity 624 towards the temporary storage cavity 621, squeezing the detergent in the temporary storage cavity 621. The pressure difference between the temporary storage cavity 621 and the outlet pipe 64 is used to activate the second check valve 66, so that the detergent in the temporary storage cavity 621 is pumped into the dispensing box 3 through the outlet pipe 64. That is, during the pressing of the pressing lever 61, one pumping action (or dispensing action) of detergent can be completed.
[0120] Second, the elastic element 67 drives the pressing rod 61 to reset, causing the pressing rod 61 to slide away from the temporary storage chamber 621 in the slide cavity 624. The pressure difference between the temporary storage chamber 621 and the liquid inlet pipe 63 is used to conduct the first check valve 65, so as to pump the detergent in the liquid storage box 5 into the temporary storage chamber 621 through the liquid inlet pipe 63. That is, during the process of resetting the pressing rod 61, a detergent extraction action (or liquid inlet action) can be completed.
[0121] Optionally, a handle 611 is provided at the end of the pressing rod 61 that is exposed outside the compression chamber 62. The side of the handle 611 away from the pressing rod 61 has a contact surface, which can be an arc surface. When the door cover 4 and the pressing rod 61 are linked, the contact surface of the handle 611 can always have a large surface area of contact with the door cover 4, so as to improve the smoothness and reliability between the door cover 4 and the pressing rod 61 during the linkage.
[0122] The elastic element 67 is disposed between the pressing rod 61 and the cavity wall of the temporary storage cavity 621 along the sliding direction of the pressing rod 61, and the elastic element 67 is configured to reset the pressing rod 61.
[0123] Optionally, the elastic element 67 includes, but is not limited to, a spring or an elastic sheet.
[0124] In the above technical solution, the press pump 6 utilizes the inlet pipe 63, the temporary storage chamber 621, and the outlet pipe 64, along with the first check valve 65 and the second check valve 66, to form a unidirectional detergent flow channel from the storage box 5 to the dispensing box 3. The pressure in the temporary storage chamber 621 is changed by the movement of the press rod 61 in the slide cavity 624, and a pressure difference is generated between the press pump 61 and the inlet pipe 63 and the outlet pipe 64, so as to draw the detergent in the storage box 5 into the temporary storage chamber 621 and pump the detergent in the temporary storage chamber 621 into the dispensing box 3. Moreover, the press pump 6 with the above-mentioned structure is simple in structure and easy to operate.
[0125] Please refer to the above. Figure 2 and Figure 3 , Figure 2 A schematic diagram of a washing machine with a dispensing box is provided; the dispensing box is shown to have two chambers. Figure 3 A schematic diagram of a washing machine with a liquid storage box is provided; it shows a structural relationship in which two liquid storage boxes are installed on the washing machine.
[0126] In some embodiments, such as Figure 2 and Figure 3 As shown, there are multiple liquid storage boxes 5, and different liquid storage boxes 5 are configured to store different detergents; the dispensing box 3 is divided into multiple chambers 31, and the multiple chambers 31 are arranged one-to-one with the multiple liquid storage boxes 5. The detergent in each liquid storage box 5 can be pumped into the chamber 31 corresponding to that liquid storage box 5 by a press pump 6.
[0127] Optionally, multiple liquid storage boxes 5 can be arranged adjacent to each other in the horizontal direction.
[0128] Optionally, the corresponding liquid storage box 5 and chamber 31 can be arranged adjacent to each other.
[0129] Optionally, in the dispensing box 3, each chamber 31 may also be provided with a siphon cap 32, which can use the siphon principle to transport the mixture of water and detergent in the chamber 31 to the washing drum.
[0130] In the above technical solution, by setting multiple liquid storage boxes 5, different detergents and care products can be stored to achieve automatic dispensing of different detergents and care products. Moreover, each liquid storage box 5 has a corresponding chamber 31 set in the dispensing box 3. After different detergents and care products are dispensed into different chambers 31, under the control of the washing machine, the water inlet structure 2 is connected to different chambers 31 according to different washing stages, so that the corresponding detergents and care products can be flushed into the washing drum by the water inlet. For example, in the washing stage, the water inlet structure 2 is connected to the chamber 31 containing detergent. After the water and detergent are mixed, the mixture can be transported into the washing drum by the siphon cap 32. Or, for example, in the rinsing stage, the water inlet structure 2 is connected to the chamber 31 containing fabric softener. After the water and fabric softener are mixed, the mixture can be transported into the washing drum by the siphon cap 32.
[0131] Please refer to the above. Figures 3 to 8 , Figure 3 and Figure 4 A schematic diagram of a liquid storage box installed on a washing machine is provided; it shows one possible installation position of the liquid storage box on the washing machine. Figure 5 A schematic diagram of the internal structure of a push-pump assembled in a liquid reservoir is provided; it shows a structural relationship between the liquid reservoir and the push-pump. Figures 6 to 8 A schematic diagram of a structure is provided showing a liquid storage box and a door cover arranged opposite each other; it illustrates a structural relationship between the liquid storage box and the door cover.
[0132] In some embodiments, such as Figure 5 As shown, a portion of the press pump 6 is disposed inside the liquid reservoir 5, and at least a portion of the press lever 61 is exposed outside the liquid reservoir 5.
[0133] For example, such as Figure 5 and Figure 6 As shown, one possible structural relationship between the press pump 6 and the liquid storage box 5 is as follows: For ease of description, a specific structure of the press pump 6 described above is used as an example. Specifically, in the press pump 6, the temporary storage chamber 621, the inlet pipe 63, the first check valve 65, the second check valve 66, and the elastic element 67 can all be disposed in the inner cavity of the liquid storage box 5. The slide cavity 624 passes through the box wall of the liquid storage box 5, and a portion of the slide cavity 624 is exposed outside the liquid storage box 5. Then, a part of the pressing rod 61 is located inside the slide cavity 624, and another part of the pressing rod 61 passes through the slide cavity 624 and is exposed outside the liquid storage box 5. The liquid outlet pipe 64 passes through the box wall of the liquid storage box 5 and a portion of the liquid outlet pipe 64 extends into the interior of the dispensing box 3.
[0134] Furthermore, such as Figure 3 As shown, the liquid storage box 5 is located on the top of the box body 1, and is close to the end where the door cover 4 is movably connected to the box body 1. With this structural design, by placing the pump 6 and the liquid storage box 5 on the top of the box body 1, it is convenient to assemble and disassemble the pump 6 and the liquid storage box 5 from the box body 1, and it is also convenient to replace and replenish the detergent in the liquid storage box 5.
[0135] For example, such as Figure 3 and Figure 4 As shown, one installation method between the liquid storage box 5 and the housing 1 is as follows: a snap-fit groove 12 is provided at the top rear end of the housing 1, and a snap-fit block is formed at the bottom of the liquid storage box 5. The liquid storage box 5 can be snapped onto the housing 1 by the snap-fit cooperation between the snap-fit block and the snap-fit groove 12. In addition, a liquid inlet 121 is also provided in the snap-fit groove 12, and the end of the liquid outlet pipe 64 away from the second communication port 623 can extend into the interior of the dispensing box 3 through the liquid inlet 121.
[0136] Optionally, the liquid storage box 5 can be positioned above the dispensing box 3, which shortens the pumping distance of the detergent and improves the smoothness of the detergent pumping by pumping the detergent from the upper liquid storage box 5 to the lower dispensing box 3.
[0137] Optionally, another part of the push rod 61 passes through the slide cavity 624 and is exposed at the front end of the liquid storage box 5, so that the push rod 61 can make better contact with the door cover 4 when the door cover 4 is opened, which can improve the smoothness and stability of the linkage between the door cover 4 and the push rod 61.
[0138] Furthermore, such as Figure 6 As shown, the door cover 4 has an outer surface 41, which is positioned away from the inlet 11 when the door cover 4 rotates about the axis 43 to fully close the inlet 11.
[0139] During the opening of the inlet 11, the outer surface 41 of the door cover 4 can directly press the pressing rod 61 and drive the pressing rod 61 to move, thereby driving the pressing pump 6 to work.
[0140] By adopting the above structural design, the outer surface 41 of the door cover 4 and the pressing rod 61 are linked together. During the opening of the door cover 4, the outer surface 41 is used to squeeze the pressing rod 61 to dispense the detergent. The fit between the outer surface 41 and the pressing rod 61 can be clearly observed, which is conducive to timely detection and handling of abnormal fit between the outer surface 41 and the pressing rod 61.
[0141] Furthermore, such as Figure 7 and Figure 8As shown, during the process of opening the inlet 11, the outer surface 41 of the door cover 4 can indirectly squeeze the pressing rod 61 and drive the pressing rod 61 to move, so as to drive the pressing pump 6 to work.
[0142] For example, such as Figure 7 and Figure 8 As shown, a specific structure that indirectly presses the pressing rod 61 using the outer surface 41 of the door cover 4 can be: an adjustable adjustment block 7 is provided on the outer surface 41 of the door cover 4, and the door cover 4 presses the pressing rod 61 through the adjustment block 7 during the opening of the inlet 11.
[0143] Optionally, a threaded groove is provided on the outer surface 41 of the door cover 4, and an external thread is provided on the outer periphery of the adjusting block 7. The height of the adjusting block 7 relative to the outer surface 41 can be adjusted by the helical connection between the external thread and the threaded groove.
[0144] When the door cover 4 rotates around the axis 43 to the maximum opening angle, the moving distance of the pressing rod 61 during the pressing process is defined as the maximum moving distance, and the amount of detergent that the pressing pump 6 can pump into the dispensing box 3 in a single operation is defined as the maximum pumping amount; wherein, the maximum moving distance is positively correlated with the maximum pumping amount.
[0145] The adjusting block 7 is configured to change the maximum travel distance of the pressing rod 61 by adjusting the height of the adjusting block 7, so as to control the maximum pumping volume of the pressing pump 6.
[0146] With the above structural design, an adjustable adjustment block 7 is set on the outer surface 41 of the door cover 4, and the adjustment block 7 is linked with the pressing rod 61. By using the adjustment block 7 at different height positions, the maximum moving distance of the pressing rod 61 can be changed during the pressing process, thereby controlling the maximum pumping volume of the pressing pump 6 and adjusting the amount of detergent added. Moreover, setting the adjustment block 7 on the outer surface 41 of the door cover 4 makes it more convenient to adjust the adjustment block 7.
[0147] Based on the above technical solution, the usage process of this embodiment can be as follows:
[0148] When a user is preparing to do laundry, they can open the door cover 4, put clothes into the washing drum, and use the opening action of the door cover 4 or the adjusting block 7 to squeeze the pressing rod 61 to drive the pressing pump 6 to work, pumping the detergent in the temporary storage chamber 621 into the dispensing box 3, completing one dispensing action.
[0149] After closing the door cover 4, during the closing process, the pressing rod 61 loses the squeezing force given by the door cover 4 or the adjusting block 7, and under the action of the elastic element 67, the pressing rod 61 resets, which can pump the detergent in the liquid storage box 5 into the temporary storage chamber 621 to complete one liquid filling action;
[0150] Then, turn on the washing machine to wash and rinse the clothes. During this process, the washing machine can be controlled to flush the corresponding detergent into the drum at different washing stages.
[0151] After the washing is finished, open the door cover 4, take out the clothes from the washing drum, and use the opening action of the door cover 4 or the adjusting block 7 to squeeze the pressing rod 61 again, and drive the pressing pump 6 to work, pumping the detergent in the temporary storage chamber 621 into the dispensing box 3 to complete the secondary liquid dispensing action. The detergent in the dispensing box 3 can be used for the next washing.
[0152] After the washing is completed, the door cover 4 can be left open to wait for the next washing; or the door cover 4 can be closed. During the closing process, the pressing rod 61 loses the squeezing force given by the door cover 4 or the adjusting block 7, and under the action of the elastic element 67, the pressing rod 61 is reset, which can pump the detergent in the liquid storage box 5 into the temporary storage chamber 621 to complete the secondary liquid filling action.
[0153] It should be noted that if you choose to close the door cover 4 after washing, you will need to open the door cover 4 again for the next wash. This action will cause the liquid to be dispensed again, and the amount of detergent in the dispensing box 3 may be too much. Therefore, you can adjust the height of the adjusting block 7 to control the amount of detergent dispensed by the pump 6 each time to meet the washing requirements.
[0154] Please refer to the above. Figure 5 as well as Figure 9 and Figure 10 , Figure 5 A schematic diagram of the internal structure of a push-pump assembled in a liquid reservoir is provided; it shows a structural relationship between the liquid reservoir and the push-pump. Figure 9 and Figure 10 A structural diagram showing the relative positional relationship between the liquid storage box and the door cover is provided; it illustrates a structural relationship in which the liquid storage box is disposed inside the box body and located below the door cover.
[0155] In some embodiments, such as Figure 5 As shown, part of the press pump 6 is disposed inside the liquid storage box 5, and at least part of the press rod 61 is exposed outside the liquid storage box 5;
[0156] For example, such as Figure 5As shown, one possible structural relationship between the press pump 6 and the liquid storage box 5 is as follows: For ease of description, a specific structure of the press pump 6 described above is used as an example. Specifically, in the press pump 6, the temporary storage chamber 621, the inlet pipe 63, the first check valve 65, the second check valve 66, and the elastic element 67 can all be disposed in the inner cavity of the liquid storage box 5. The slide cavity 624 passes through the box wall of the liquid storage box 5, and a portion of the slide cavity 624 is exposed outside the liquid storage box 5. Then, a part of the pressing rod 61 is located inside the slide cavity 624, and another part of the pressing rod 61 passes through the slide cavity 624 and is exposed outside the liquid storage box 5. The liquid outlet pipe 64 passes through the box wall of the liquid storage box 5 and a portion of the liquid outlet pipe 64 extends into the interior of the dispensing box 3.
[0157] Furthermore, such as Figure 9 As shown, the liquid storage box 5 is located inside the cabinet 1. When the door cover 4 is fully closed, the liquid storage box 5 is located below the door cover 4. By adopting the above structural design, and placing the pump 6 and the liquid storage box 5 inside the cabinet 1 and below the door cover 4, the appearance of the washing machine can be made more beautiful and neat.
[0158] Optionally, the liquid storage box 5 can be arranged adjacent to the dispensing box 3 and located on the periphery of the dispensing box 3, which shortens the pumping distance of the detergent and improves the smoothness of the detergent pumping.
[0159] Optionally, another part of the pressing lever 61 passes through the slide cavity 624 and is exposed above the liquid storage box 5, so that the pressing lever 61 can make better contact with the door cover 4 when the door cover 4 is closed, which can improve the smoothness and stability of the linkage between the door cover 4 and the pressing lever 61.
[0160] Furthermore, such as Figure 9 As shown, the door cover 4 has an inner surface 42, which faces the inlet 11 when the door cover 4 is rotated about the axis 43 to fully close the inlet 11.
[0161] During the process of closing the inlet 11, the inner surface 42 of the door cover 4 can directly press the pressing rod 61 and drive the pressing rod 61 to move, so as to drive the pressing pump 6 to work.
[0162] By adopting the above structural design, the inner surface 42 of the door cover 4 and the pressing rod 61 are linked together. During the closing process of the door cover 4, the inner surface 42 is used to squeeze the pressing rod 61 to dispense detergent. This makes it easier to apply force to the door cover 4 and allows for a greater pressing force to be applied to the pressing rod 61. Moreover, under the weight of the door cover 4, the lever principle can be used to automatically press the pressing rod 61 during the closing and falling process of the door cover 4, which saves the user effort.
[0163] Furthermore, such as Figure 10As shown, during the process of closing the inlet 11, the inner surface 42 of the door cover 4 can indirectly squeeze the pressing rod 61 and drive the pressing rod 61 to move, so as to drive the pressing pump 6 to work.
[0164] For example, such as Figure 10 As shown, a specific structure that indirectly presses the push rod 61 using the inner surface 42 of the door cover 4 can be: an adjustable adjustment block 7 is provided on the inner surface 42 of the door cover 4, and the door cover 4 presses the push rod 61 through the adjustment block 7 during the closing of the inlet 11.
[0165] Optionally, a threaded groove is provided on the inner surface 42 of the door cover 4, and an external thread is provided on the outer periphery of the adjusting block 7. The height of the adjusting block 7 relative to the inner surface 42 can be adjusted by the helical connection between the external thread and the threaded groove.
[0166] When the door cover 4 rotates around the axis 43 to fully close the inlet 11, the maximum moving distance of the pressing rod 61 during the pressing process is defined as the maximum moving distance, and the maximum pumping amount of detergent that the pressing pump 6 can pump into the dispensing box 3 in a single operation is defined as the maximum pumping amount; wherein, the maximum moving distance is positively correlated with the maximum pumping amount.
[0167] The adjusting block 7 is configured to change the maximum travel distance of the pressing rod 61 by adjusting the height of the adjusting block 7, so as to control the maximum pumping volume of the pressing pump 6.
[0168] With the above structural design, an adjustable adjustment block 7 is set on the inner surface 42 of the door cover 4, and the adjustment block 7 is linked with the pressing rod 61. By using the adjustment block 7 at different height positions, the maximum moving distance of the pressing rod 61 can be changed during the pressing process, thereby controlling the maximum pumping volume of the pressing pump 6 and adjusting the amount of detergent added. Moreover, setting the adjustment block 7 on the inner surface 42 of the door cover 4 makes the washing machine look more beautiful and neat.
[0169] Based on the above technical solution, the usage process of this embodiment can be as follows:
[0170] When a user is preparing to do laundry, they open the door cover 4, put clothes into the washing drum, and use the opening action of the door cover 4 to move the door cover 4 or the adjusting block 7 away from the pressing rod 61. The pressing rod 61 loses the squeezing force given by the door cover 4 or the adjusting block 7, and under the action of the elastic element 67, the pressing rod 61 returns to its original position, which can pump the detergent in the liquid storage box 5 into the temporary storage chamber 621, completing one liquid filling action;
[0171] Then close the door cover 4. During the closing process, the closing action of the door cover 4 can be used to make the door cover 4 or the adjusting block 7 squeeze the pressing rod 61 to drive the pressing pump 6 to work and pump the detergent in the temporary storage chamber 621 into the dispensing box 3 to complete one dispensing action.
[0172] Then, turn on the washing machine to wash and rinse the clothes. During this process, the washing machine can be controlled to flush the corresponding detergent into the drum at different washing stages.
[0173] After the washing is completed, open the door cover 4, take out the clothes from the washing drum, and use the opening action of the door cover 4 to move the door cover 4 or the adjusting block 7 away from the pressing rod 61 again. The pressing rod 61 is reset under the action of the elastic element 67, and the detergent in the liquid storage box 5 is pumped into the temporary storage chamber 621 to complete the secondary liquid filling action.
[0174] After the washing is completed, the door cover 4 can be left open to wait for the next washing; or the door cover 4 can be closed. During the closing process, the closing action of the door cover 4 causes the door cover 4 or the adjusting block 7 to press the pressing rod 61 and drive the pressing pump 6 to work, pumping the detergent in the temporary storage chamber 621 into the dispensing box 3 to complete the secondary dispensing action. The detergent in the dispensing box 3 can be used for the next washing.
[0175] It should be noted that if you choose to close the door cover 4 after washing, you will need to open and close the door cover 4 again when loading clothes for the next wash. This closing action of the door cover 4 will cause the liquid to be dispensed again, which may result in too much detergent being added to the detergent dispenser 3. Therefore, you can adjust the height of the adjusting block 7 to control the amount of detergent dispensed by the pump 6 each time to meet the washing requirements.
[0176] The embodiments of this disclosure also provide a washing machine. The main difference between the washing machine in this embodiment and the washing machine in the embodiments described above is that: the door cover 4 is provided with a height-adjustable adjustment block 7, and the adjustment block 7 is provided with a second height position. When the adjustment block 7 is in the second height position, during the process of opening or closing the inlet 11 of the door cover 4, the door cover 4 and the adjustment block 7 do not apply force to the pressing rod 61, and the door cover 4 and / or the adjustment block 7 will not form a linkage with the pressing rod 61; that is, the washing machine can realize the automatic dispensing function closing.
[0177] Specifically, the washing machine includes a cabinet 1, a door cover 4, a liquid storage box 5, and a pump 6. The cabinet 1 has an inlet 11, and its interior includes a water inlet structure 2, a dispensing box 3, and a washing drum. The water inlet structure 2 is configured to guide external water through the dispensing box 3 into the washing drum. The door cover 4 is movably connected to the cabinet 1 via a shaft 43 to open or close the inlet 11. The liquid storage box 5 stores detergent. The pump 6 includes a pressing lever 61, which is configured to drive the pump 6 by applying force to pump the detergent from the liquid storage box 5 into the dispensing box 3.
[0178] The door cover 4 is equipped with a height-adjustable adjustment block 7.
[0179] Optionally, a threaded groove is provided on the door cover 4, and an external thread is provided on the outer periphery of the adjusting block 7. The height of the adjusting block 7 relative to the door cover 4 can be adjusted by the helical connection between the external thread and the threaded groove.
[0180] The height position of adjustment block 7 includes at least a first height position and a second height position.
[0181] When the adjusting block 7 is in the first height position, during the process of opening or closing the inlet 11 of the door cover 4, the adjusting block 7 and the pressing rod 61 form a linkage. The adjusting block 7 can apply force to press the pressing rod 61 and drive the pressing rod 61 to move, so as to drive the pressing pump 6 to work.
[0182] When the adjusting block 7 is in the second height position, neither the door cover 4 nor the adjusting block 7 applies force to the pressing lever 61 during the opening or closing of the inlet 11. For example, when the adjusting block 7 is fully screwed into the door cover 4, the door cover 4 and the adjusting block 7 will never contact the pressing lever 61, thus closing the automatic detergent dispensing function.
[0183] In the above technical solution, the opening and closing action and stroke of the door cover 4 are used to make the adjusting block 7 and the pressing rod 61 work together. Since the user will open and close the door cover 4 at least once each time they wash clothes, the movement of the door cover 4 during this action mechanically squeezes the pressing rod 61, driving the pressing pump 6 to work. This pumps a certain amount of detergent from the storage box 5 into the dispensing box 3, thus achieving the automatic dispensing function of detergent. Furthermore, by using the adjusting block 7 at different heights, the maximum movement distance of the pressing rod 61 can be changed during the squeezing process, thereby controlling the maximum pumping volume of the pressing pump 6 and adjusting the amount of detergent dispensed. Additionally, by adjusting the height of the adjusting block 7, the door cover 4 and the adjusting block 7 can be kept from applying pressure to the pressing rod 61, thus turning off the automatic dispensing function.
[0184] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and not to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure, and they should all be covered within the scope of the claims and specification of this disclosure.
