Description

A dispensing device and a control method for a washing machine Technical Field

[0001] The present invention belongs to the field of clothing cleaning, and in particular relates to a feeding device and a control method for a washing machine. Background Art

[0002] The clothing treatment device is a frequently used household appliance. It is equipped with an additive dispensing device, which primarily comprises a water box connected to the water inlet pipe of the clothing treatment device and a liquid storage box contained within the water box. The liquid storage box is typically configured to be retractable within the water box, allowing the user to pull the liquid storage box out of the water box and add additives such as detergent, softener, and / or disinfectant. After water begins to flow into the clothing treatment device, the liquid pumping device draws the additives from the liquid storage box and dispenses them into the water channel of the water box. Water in the water inlet pipe first enters the water channel of the water box, where it is fully mixed with the additives before flowing into the clothing treatment device.

[0003] In daily use, some users are only accustomed to using detergent or are accustomed to hand-washing clothes and then rinsing clothes in the washing machine, so that only detergent or softener is stored in the dispensing device, resulting in the softener storage box or the detergent storage box being idle all the time, causing space waste. At the same time, the capacity of the detergent storage box or the softener storage box is relatively small, which requires users to frequently replenish the corresponding additives, which is very troublesome.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a dispensing device and a control method for a washing machine. By opening a connecting port on the side wall between the two liquid storage chambers and correspondingly setting a partition structure, the user can connect or disconnect the two liquid storage chambers as needed, thereby solving the problem that when the user only uses one additive, the liquid storage chamber of the other additive is idle and not reasonably utilized.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a dosing device, including a water box; a liquid storage box, installed inside the water box, a first liquid storage chamber is provided inside the liquid storage box, the first liquid storage chamber pumps the additive stored inside to the flow channel of the water box by setting a first liquid pumping component; a second liquid storage chamber is also provided in the liquid storage box, the second liquid storage chamber is provided with a second liquid pumping component, and the liquid outlet end of the second liquid pumping component is connected to the flow channel of the water box; a connecting port is provided on the adjacent side walls of the first liquid storage chamber and the second liquid storage chamber, and a partition structure is provided in the liquid storage box, and the partition structure can be opened and closed to seal the connecting port.

[0007] Furthermore, the partition structure is a partition door, which can be switched between a first position and a second position. In the first position, the outer peripheral edge of the partition door is sealed and fitted with the edge of the connecting port; in the second position, the partition door is spaced apart from the edge of the connecting port.

[0008] Furthermore, the partition structure includes a rotating shaft rotatably arranged in the liquid storage box, and the partition door is set on the rotating shaft and rotates synchronously with the rotating shaft.

[0009] Furthermore, the rotating shaft is arranged vertically, and the top end of the rotating shaft passes through the upper cover of the liquid storage box, and the top end of the rotating shaft is connected to a bent and extended toggle portion; a first gear rib and a second gear rib are provided on the upper surface of the cover of the liquid storage box, and when the partition door is in the first position or the second position, the toggle portion correspondingly abuts against the first gear rib or the second gear rib.

[0010] Furthermore, the lower side of the communication port is flush with the bottom of the first liquid storage cavity and the bottom of the second liquid storage cavity respectively.

[0011] Furthermore, the bottom of the first liquid storage chamber is lower than the bottom of the second liquid storage chamber, and the lower side of the communication port is tilted downward from the side close to the second liquid storage chamber to the side close to the first liquid storage chamber.

[0012] A control method for a washing machine includes a dispensing device as described above; before executing a washing program, the opening and closing status of a partition structure is obtained, and the dispensing mode of the dispensing device is adjusted accordingly according to the opening and closing status of the partition structure.

[0013] Furthermore, before executing the washing program, it is determined whether the partition structure is opened;

[0014] If so, it is determined that only one type of additive is stored in the dispensing device, the type of the additive is obtained, and when executing the corresponding stage of the washing program corresponding to the additive, the automatic dispensing device is controlled to extract the additive;

[0015] If not, when the washing machine performs different stages of the washing program, the liquid pumping assembly corresponding to the washing stage is enabled to pump the additive.

[0016] Furthermore, when it is determined that only one type of additive is stored in the dispensing device, the type of the stored additive is confirmed to the user, and according to the selected additive type, the washing machine is controlled to extract the additive when executing the washing stage or the rinsing stage of the washing program.

[0017] Furthermore, when it is determined that only one type of additive is stored in the dispensing device, during the corresponding stage of the washing program, the first liquid extraction component and the second liquid extraction component are controlled to extract the additive simultaneously.

[0018] Furthermore, the bottom height of the first liquid storage chamber is lower than the bottom height of the second liquid storage chamber; when only one additive is stored in the dosing device, the real-time liquid level height of the additive in the dosing device is obtained during the corresponding stage of the washing program, and when the real-time liquid level height is less than the preset first liquid level height, the second liquid pumping component is closed.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: by opening a communication port on the side wall between the two liquid storage chambers and correspondingly setting a partition structure, when the user only uses one additive, the two liquid storage chambers are connected by opening the partition structure, so that the two chambers of the dispensing device can store and use the same additive at the same time, thereby greatly reducing the frequency of users replenishing additives and improving the user experience.

[0020] At the same time, the present invention has a simple structure, significant effects, and is suitable for popularization and use.

[0021] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0032] As shown in Figures 1 and 2, in an embodiment of the present invention, a dosing device is introduced, including a water box; a liquid storage box 1, which is installed inside the water box, and a first liquid storage chamber 110 is provided inside the liquid storage box 1. The first liquid storage chamber 110 pumps the additive stored inside to the flow channel of the water box by setting a first liquid pumping component 111; a second liquid storage chamber 120 is also provided in the liquid storage box 1, and the second liquid storage chamber 120 is provided with a second liquid pumping component 121, and the liquid outlet end of the second liquid pumping component 121 is connected to the flow channel of the water box; a connecting port 130 is provided on the adjacent side walls of the first liquid storage chamber 110 and the second liquid storage chamber 120, and a partition structure 140 is provided in the liquid storage box 1, and the partition structure 140 can be opened and closed to seal the connecting port 130.

[0033] Through the above-mentioned arrangement, by opening a communication port 130 on the side wall between the two liquid storage chambers and correspondingly setting a partition structure 140, when the user only uses one additive, the two liquid storage chambers are connected by opening the partition structure 140, so that the two chambers of the dosing device can store and use the same additive at the same time, thereby greatly reducing the frequency of the user's replenishment of additives and improving the user's usage experience.

[0034] In the embodiment of the present invention, the partition structure 140 is a solenoid valve, the outer peripheral side wall of the solenoid valve is fixed on the peripheral side edge of the communication port 130; the two liquid storage chambers are connected or disconnected by turning the solenoid valve on and off.

[0035] In an embodiment of the present invention, the partition structure 140 is a partition door 141, which can be switched between a first position and a second position. In the first position, the outer peripheral edge of the partition door 141 is sealed and fitted with the edge of the connecting port 130; in the second position, the partition door 141 is spaced apart from the edge of the connecting port 130.

[0036] Through the above-mentioned setting, by setting the partition door 141 and moving the partition door 141, the partition door 141 can be correspondingly blocked or opened for the connecting port 130; at the same time, in addition to setting the partition door 141 to be electrically controlled, the user can manually operate the partition door 141 to open or block the connecting port 130, which is convenient for the user to use while simplifying the complexity of the delivery device and reducing costs.

[0037] In an embodiment of the present invention, a slide is provided at the bottom of the first liquid storage chamber 110 and / or the second liquid storage chamber 120, and the partition door 141 is slidably provided on the slide; the partition door 141 can be opened or closed by sliding on the slide, and the connecting port 130 is simple in structure and easy to use.

[0038] In an embodiment of the present invention, a slot recessed inward is provided on the bottom end surface of the partition door 141, and at least two upwardly protruding protrusions are correspondingly provided on the slide. The two protrusions are arranged at a distance from one end along the extension direction of the slide, and one of the protrusions is located in the connecting port 130. The partition door 141 can be selectively engaged with the corresponding protrusion through the slot; by making the partition door 141 engage with the protrusion in the connecting port 130, or engage with another protrusion, the partition door 141 is limited to a position of blocking the connecting port 130 or opening the connecting port 130, thereby improving the working stability of the feeding device and preventing shaking during the operation of the washing machine, which pushes the partition door 141 to shift; at the same time, when it is necessary to switch the connection state of the two liquid storage chambers, the partition door 141 can be disengaged from the currently engaged protrusion and slid to the other protrusion by sliding the partition door 141 with force. The operation is simple and convenient, and the failure rate is low.

[0039] In an embodiment of the present invention, the partition structure 140 includes a rotating shaft 143 rotatably arranged in the liquid storage box 1, and the partition door 141 is mounted on the rotating shaft 143 and rotates synchronously with the rotating shaft 143; by rotating the door body around the axis, the movement amplitude of the partition structure 140 when opening and closing is reduced, and the rotation can be achieved through simple mechanical transmission, thereby improving the stability of the operation of the partition structure 140.

[0040] In the embodiment of the present invention, the rotating shaft 143 is vertically arranged, and the lower end of the rotating shaft 143 is rotatably connected to the lower side of the communication opening 130 , and the partition door 141 is rotatably embedded in the communication opening 130 .

[0041] In the embodiment of the present invention, a rotation groove recessed inward is provided on the lower side of the communication port 130 , and the lower end of the rotation shaft 143 is rotatably disposed in the rotation groove.

[0042] In an embodiment of the present invention, the rotating groove is a cylindrical groove body coaxially arranged with the rotating shaft 143, and an annular positioning groove recessed inward is provided on the circumferential groove wall of the rotating groove, and a radially outwardly protruding positioning rib is provided on the circumferential side wall of the lower end of the rotating shaft 143. The positioning rib can be rotated around the rotating shaft 143 and engaged in the positioning groove; so as to limit the rotating shaft 143 in the vertical direction and prevent the rotating shaft 143 from falling out of the rotating groove.

[0043] In an embodiment of the present invention, the positioning ribs are arranged circumferentially around the rotating shaft 143, and each positioning rib is set at a certain distance to reduce the sliding friction between the positioning ribs and the positioning grooves. At the same time, when the rotating shaft 143 is disassembled, each positioning rib can be elastically deformed toward the spacing space, thereby reducing the difficulty of the rotating shaft 143 being disengaged from the positioning groove.

[0044] In an embodiment of the present invention, the rotating shaft 143 is vertically arranged, and the top end of the rotating shaft 143 passes through the upper cover 150 of the liquid storage box 1, and the top end of the rotating shaft 143 is connected to a bent and extended toggle portion 144; a first gear rib 151 and a second gear rib 152 are provided on the upper surface of the cover 150 of the liquid storage box 1, and when the partition door 141 is in the first position or the second position, the toggle portion 144 correspondingly abuts against the first gear rib 151 or the second gear rib 152.

[0045] Through the above-mentioned arrangement, without disassembling the cover 150 of the liquid storage box 1, the user can rotate the partition door 141 by turning the toggle portion 144, which is convenient for the user to operate manually; at the same time, by allowing the top end of the rotating shaft 143 to pass through the cover 150 of the liquid storage box 1, the upper end of the rotating shaft 143 is fixed more firmly, thereby improving the limiting effect of the radial direction of the rotating shaft 143; in addition, by arranging the first gear rib 151 and the second gear rib 152 on the top of the water box, the rotation angle of the rotating shaft 143 and the partition door 141 is limited to prevent the partition door 141 from excessive rotation, resulting in the partition door 141 not tightly blocking the connecting port 130.

[0046] In the embodiment of the present invention, the extending direction of the toggle portion 144 is arranged parallel to the partition door 141 , and the toggle portion 144 and the partition door 141 are located in the same radial direction of the axis of the rotating shaft 143 .

[0047] In an embodiment of the present invention, the partition door 141 located at the first position and the partition door 141 located at the second position are arranged perpendicular to each other; so that when the partition door 141 is opened, the area overlapping with the connecting port 130 is minimized, and the connection effect between the first liquid storage chamber 110 and the second liquid storage chamber 120 is optimal.

[0048] In an embodiment of the present invention, a first liquid injection port and a second liquid injection port are provided on the cover body 150 of the liquid storage box 1. The first liquid injection port and the second liquid injection port are respectively located above the first liquid storage cavity 110 and the second liquid storage cavity 120, so that the user can add additives to the corresponding liquid storage cavity through each injection port.

[0049] In an embodiment of the present invention, support columns are respectively provided in the first liquid storage chamber 110 and the second liquid storage chamber 120, the top ends of the support columns are in contact with the cover body 150, and the support columns are respectively staggered with respect to the direction of the connecting port 130; so as to prevent the support columns from hindering the additives in each liquid storage chamber from flowing into the other liquid storage chamber.

[0050] In the embodiment of the present invention, the top end surfaces of the adjacent side walls of the first liquid storage cavity 110 and the second liquid storage cavity 120 are provided with downwardly concave notches, which cooperate with the cover 150 of the liquid storage box 1 to form a communication port 130.

[0051] In an embodiment of the present invention, partition grooves with an upward opening are provided on the top end faces of the adjacent side walls of the first liquid storage chamber 110 and the second liquid storage chamber 120 along the extension direction of the side walls, and strip-shaped partition ribs with protruding surfaces are provided on the lower surface of the cover body 150, and the partition ribs are sealed and inserted into the partition grooves to limit the cover body 150 in the horizontal direction.

[0052] In an embodiment of the present invention, the lower side edge of the communication port 130 is flush with the bottom of the first liquid storage chamber 110 and the second liquid storage chamber 120 respectively; when it is necessary to divert all the additives in the first liquid storage chamber 110 or the second liquid storage chamber 120 to the other liquid storage chamber, by making the lower side edge of the communication port 130 flush with the bottom of the two chambers, the additives can be prevented from remaining near the communication port 130.

[0053] In an embodiment of the present invention, the bottom of the first liquid storage chamber 110 is lower than the bottom of the second liquid storage chamber 120, and the lower side edge of the connecting port 130 is tilted downward from the side close to the second liquid storage chamber 120 to the side close to the first liquid storage chamber 110; by sinking the height position of the bottom of the first liquid storage chamber 110, when the first liquid storage chamber 110 and the second liquid storage chamber 120 are connected, the first liquid storage chamber 110 serves as the main liquid storage chamber. When there are fewer additives, all additives are gathered in the first liquid storage chamber 110 to reduce the horizontal area of ​​the additives and increase the liquid level, so as to facilitate the first liquid extraction component 111 to extract all the additives in the delivery box to avoid additive residue.

[0054] In an embodiment of the present invention, the lower side edge of the partition door 141 is correspondingly provided with an inclined surface that is in contact with the lower side edge of the connecting port 130; when the partition door 141 switches from the first position to the second position, the partition door 141 rotates around the rotation axis 143 into the first liquid storage chamber 110.

[0055] In an embodiment of the present invention, a stop portion extending outward is provided on the outer peripheral edge of the side wall of the partition door 141 facing the first liquid storage chamber 110, and the stop portion is arranged to fit the adjacent side walls of the first liquid storage chamber 110 and the second liquid storage chamber 120, so that when the partition door 141 is switched from the second position to the first position, the stop portion abuts against the adjacent side wall to position the partition door 141 and prevent it from continuing to rotate. At the same time, the stop portion has a larger abutment area with the side wall, thereby improving the stability of the partition door 141 in blocking the connecting port 130.

[0056] As shown in Figures 1-4, in an embodiment of the present invention, a control method for a washing machine is also introduced. The washing machine includes a dispensing device as described above; before executing the washing program, the opening and closing status of the partition structure 140 is obtained, and the dispensing method of the dispensing device is adjusted accordingly according to the opening and closing status of the partition structure 140.

[0057] Through the above-mentioned arrangement, during the operation of the washing machine, by confirming the opening and closing status of the partition structure 140, it is determined whether the first liquid storage chamber 110 and the second liquid storage chamber 120 of the dispensing device are connected. In this way, the additives stored in each liquid storage chamber can be judged to prevent the softener or detergent from being mistakenly dispensed into the washing chamber of the washing machine during the washing stage or the rinsing stage.

[0058] In an embodiment of the present invention, the washing machine is a drum-type washing machine, a pulsator-tub-type washing machine, or a washing machine having both a pulsator tub and a drum.

[0059] In an embodiment of the present invention, before executing the washing program, it is determined whether the partition structure 140 is open; if so, it is determined that only one type of additive is stored in the dispensing device, the type of the additive is obtained, and when the corresponding stage of the washing program corresponding to the additive is executed, the automatic dispensing device is controlled to extract the additive; if not, when the washing machine executes different stages of the washing program, the liquid extraction component corresponding to the washing stage is instructed to extract the additive.

[0060] Through the above arrangement, after determining that the first liquid storage chamber 110 and the second liquid storage chamber 120 are connected, the type of additive is determined to determine at which stage of the washing process of the washing machine the automatic dosing needs to be performed; for example, when the user is accustomed to pouring detergent directly into the washing drum of the washing machine and only using the dosing device to dispense softener, by confirming that the type of the additive is softener, during the washing stage, the dosing device is closed or only used to conduct water inlet; during the rinsing stage, the dosing device performs the dosing work and dispenses softener into the washing drum of the washing machine.

[0061] In an embodiment of the present invention, before executing the washing program, the position of the partition door 141 is obtained to determine whether the partition door 141 is located in the second position. If so, the partition structure 140 is determined to be open; if not, the partition structure 140 is determined to be closed.

[0062] In an embodiment of the present invention, a detection component is provided in the dispensing device. When it is determined that only one type of additive is stored in the dispensing device, the detection component is controlled to detect the type of additive. According to the detected type of additive, when the washing machine executes the corresponding stage of the washing program, the dispensing device is controlled to perform the dispensing work.

[0063] In an embodiment of the present invention, the detection component is a conductivity detection component, which detects the conductivity of the additive and determines the type of the additive based on different detected conductivity values.

[0064] In an embodiment of the present invention, when it is determined that only one type of additive is stored in the dispensing device, the type of the stored additive is confirmed to the user, and according to the selected additive type, the washing machine is controlled to extract the additive when executing the washing stage or the rinsing stage of the washing program; the type of additive automatically dispensed by the washing machine is confirmed by the user to ensure that the washing machine accurately dispenses the additive.

[0065] In an embodiment of the present invention, a washing machine is provided with a single-dispensing detergent box and a single-dispensing softener button; when the washing machine determines that only one type of additive is stored in the dispensing device, the type of the stored additive is confirmed to the user, and it is determined whether the single-dispensing detergent button is triggered by the user; if so, the dispensing device is controlled to operate when the washing machine executes the washing stage of the washing program; if not, the dispensing device is controlled to operate when the washing machine executes the rinsing stage of the washing program.

[0066] In an embodiment of the present invention, when it is determined that only one type of additive is stored in the dispensing device, during the corresponding stage of the washing program, the first liquid pumping component 111 and the second liquid pumping component 121 are controlled to extract the additive simultaneously; when the first liquid storage chamber 110 and the second liquid storage chamber 120 of the dispensing device are connected, the dispensing efficiency of the dispensing device is improved and the dispensing time is shortened by making the two liquid pumping components work simultaneously.

[0067] In an embodiment of the present invention, the bottom height of the first liquid storage chamber 110 is lower than the bottom height of the second liquid storage chamber 120; when only one additive is stored in the dosing device, the real-time liquid level height of the additive in the dosing device is obtained during the corresponding stage of the washing program, and when the real-time liquid level height is less than the preset first liquid level height, the second liquid pumping component 121 is closed.

[0068] Through the above-mentioned setting, by making the first liquid storage chamber 110 as the main injection chamber, when the amount of additives is small, the remaining additives are collected in the first liquid storage chamber 110, and the bottoms of the two liquid storage chambers are located at the same height. This effectively increases the liquid level of the additives, facilitates the suction component to suck the additives, and avoids the idling of the suction component or the entry of air into the suction chamber of the suction component.

[0069] In an embodiment of the present invention, the control steps of the washing machine include:

[0070] S1: The washing machine is turned on;

[0071] S2: Obtain the position information of the partition door and determine whether the partition door 141 is located at the second position. If so, execute S3; if not, execute S10;

[0072] S3: Confirm with the user whether the stored additive is detergent. If yes, execute S4; if not, execute S5;
