Description

Technical Field

[0001] The invention relates to a feeding box for a washing device, a corresponding washing device, a corresponding method for operating a washing device and a corresponding computer program product. Background Art

[0002] The function of the feeding box of a washing machine is to provide users with a carrier for feeding detergents and other substances. Therefore, the feeding box will have a feeding area or multiple independent feeding areas to meet the needs of users to feed detergents, disinfectants, softeners, etc.; because the purpose of the washing program is different, water will enter different areas of the feeding box when entering and carry different detergents, etc. into the washing drum. Usually, several areas of the feeding box are open. For liquid detergents, they will automatically flow out of the feeding box due to gravity after being added; for solid particles of washing powder, they will flow out of the feeding box with the water. However, because it will flow through many pipes from the feeding box to the washing drum, some washing liquid or washing powder particles that have not been diluted by water will remain in the pipes, and these pipes cannot be cleaned by users. Therefore, over time, there will be some hygienic problems such as stains or mold in the pipes. Even some laundry detergents / washing powders will adhere to the side walls of the washing drum or the door of the washing machine, causing waste or unclean washing. What's worse, the laundry detergent may be directly discharged from the drum without playing its due cleaning role.

[0003] In order to solve the above problem, some feeding boxes have some blocking structures at the opening position, but this solution has not achieved real effect. Instead, some laundry detergent or laundry powder will remain in the feeding box or the blocking structure and other parts. After a long time, the laundry detergent will condense or the laundry powder will clump, affecting the user's hygienic use.

[0004] Some people also consider strengthening the mixing to avoid this situation as much as possible, and use a mixer for this purpose. However, the end of the feeding box is open, which cannot effectively keep the liquid, and the mixing effect is poor. In addition, some mixers have problems such as complex structure and leakage.

[0005] Therefore, there is a need for continued improvement. Summary of the invention

[0070] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention clearer, the present invention will be further described in detail in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the scope of protection of the present invention, and each embodiment may share the same view or multiple views for description, but all features appearing in the same figure cannot be interpreted as features that must be possessed by an embodiment. On the contrary, as long as they are not mutually exclusive technically, they can be combined in any suitable manner. Moreover, for the sake of simplicity, different embodiments of different aspects may be presented in the same specific design, but such presentation does not mean that the embodiments of these aspects should appear together. The disassembly and / or combination of all possible embodiments and / or technical features should also take into account the description of the specification and the content that can be directly and unambiguously determined by those skilled in the art based on the description of the specification.

[0071] Before starting the description, it should be pointed out that, for the sake of convenience, this document may use directional terms or direction terms for description, and the directional terms or direction terms are relative to the normal use state of the washing device. Those skilled in the art can clearly understand this from the description of the present invention without causing confusion. In this case, the directional terms and direction terms should not be simply interpreted as the directional terms or directions in any state.

[0072] Moreover, the ordinal numbers such as "first" and "second" in this specification are provided to avoid confusion among constituent elements, rather than to limit the quantity, nor do they mean that there is any difference in importance between them.

[0073] It must also be pointed out that due to the proportional relationship, the limitation of the space of the figure markings, etc., in the following description, it may be necessary to refer to multiple figures at the same time for understanding.

[0074] The present invention mainly relates to a feeding box of a washing device. A user and / or an automatic feeding device can feed various required substances (also referred to as feeding) into a washing drum of the washing device through the feeding box, for example, detergent, softener, disinfectant, etc. Those skilled in the art can understand it by taking a drum washing machine as an example, but the feeding box of the present invention can also be applied to any other suitable type of washing device in principle.

[0075] Figure 1 Taking a drum washing machine as an example, a three-dimensional view of a washing device 100 according to an exemplary embodiment of the present invention is shown. The feeding box 1 is usually arranged as a pull-out structure at the upper left corner area of ​​the front of the drum washing machine, but in practice it can also be arranged in other areas according to specific circumstances and specific designs.

[0076] Figure 2 A schematic principle diagram of a feeding box 1 according to an exemplary embodiment of the present invention is shown.

[0077] First, if Figure 2 As shown, according to a first exemplary aspect of the present invention, there is provided a feeding box 1 for a washing device 100, comprising: a liquid storage chamber 11 for receiving feeding, the liquid storage chamber 11 having a discharge port 111; a discharge door mechanism 12, the discharge door mechanism 12 comprising a discharge door 121 for opening and closing the discharge port 111; and a stirring mechanism 13 for stirring the liquid in the liquid storage chamber 11.

[0078] Here, the "discharge" in the terms "discharge port" and the like means that in the working state, when the discharge door 121 is opened, the liquid in the liquid storage chamber 11 can flow out of the liquid storage chamber 11 by gravity, especially can flow out completely by itself without the need for other special conveying devices. This allows the liquid to pour into the washing tub. On the one hand, pouring can give the liquid greater kinetic energy and better mix and spread on the clothes in the washing tub. On the other hand, it can also simplify the structure, for example, the conveying device can be omitted.

[0079] By providing the stirring mechanism 13, the liquid in the liquid storage chamber 11 can be fully mixed with the feed, and the controllable opening of the discharge port 111 can make the liquid and the feed fully mixed to a certain degree before being discharged, thereby avoiding the problem of insufficient dissolution. In addition, the controllable opening also provides flexibility to the control strategy.

[0080] According to an exemplary embodiment of the present invention, the discharge door mechanism 12 is configured to at least be able to actively control the opening of the discharge door 121 .

[0081] Here, "active control" means being able to actively choose whether and when to open (especially close) the discharge door 121. The discharge door 121 is not pushed open by the pressure generated by the gravity of the liquid in the liquid storage chamber 11, because it cannot be actively controlled, especially the opening time cannot be actively controlled. Different mixing times may be required for different feed materials, and the active control of the present invention provides flexibility for the control strategy.

[0082] In particular, according to an exemplary embodiment of the present invention, the discharge door mechanism 12 is configured to actively open the discharge door 121 at least in response to a control instruction, especially an electrical signal, issued by a controller (not shown) of the washing device 100 .

[0083] As described above, according to an exemplary embodiment of the present invention, the liquid storage chamber 11 is configured to be able to discharge all the liquid in the liquid storage chamber 11 when the discharge port 111 is opened. At this time, the discharge port 111 may be the lowest point of the liquid storage chamber 11. It is particularly preferred that the bottom of the liquid storage chamber 11 extends downwardly and obliquely toward the discharge port 111, for example, in a funnel shape to gather the liquid toward the discharge port 111.

[0084] According to an exemplary embodiment of the present invention, the discharge port 111 is disposed at the side or bottom of the liquid storage chamber 11. This may be determined according to the specific design of the discharge door mechanism 12 or other structures. Compared with being disposed at the bottom, being disposed at the side can relatively reduce the force required to seal the discharge port 111.

[0085] like Figure 2 As shown, according to an exemplary embodiment of the present invention, the discharge door mechanism 12 is configured to change the discharge door 121 from a closed state to an open state by moving outward. This outward opening mode can make the liquid flow out of the liquid storage chamber 11 smoothly, which is also beneficial to the arrangement of the discharge door mechanism 12.

[0086] According to an exemplary embodiment of the present invention, the discharge door 121 is configured to achieve the transition between the closed state and the open state by swinging. This can be easily achieved by a lever mechanism, simplifying the structure of the discharge door mechanism 12. In particular, this can be better understood in conjunction with the more specific embodiments described below.

[0087] According to an exemplary embodiment of the present invention, the discharge door mechanism 12 further includes a driving device 122 for driving the discharge door 121, which is at least partially located outside the liquid storage chamber 11. In particular, when the driving device 122 is an electric driving device, the driving device 122 can be arranged at other safer locations. On the contrary, if the driving device 122 is arranged in the liquid storage chamber 11, good insulation protection is required, and the mixing in the liquid storage chamber 11 will also be affected.

[0088] Figure 3 A top view of a feeding box 1 according to an exemplary embodiment of the present invention is shown. Figure 4 Shows Figure 3 The feeding box 1 shown is along Figure 3 However, for the sake of clarity and better understanding, Figure 3 After cutting along the cutting line AA, it is rotated 90 degrees counterclockwise to form Figure 4 When the feeding box 1 is a pull-out structure, Figure 3 The upper and lower directions shown may actually correspond to the pulling direction, for example, the lower end corresponds to the outer end, and the upper end corresponds to the inner end.

[0089] like Figure 3 and Figure 4 As shown, according to an exemplary embodiment of the present invention, the driving device 122 includes an actuator 1221 located outside the liquid storage chamber 11 and a transmission mechanism 1222 for transmitting the actuation action of the actuator 1221 to the discharge door 121 .

[0090] like Figure 3 As shown, the transmission mechanism 1222 may include a lever mechanism. Preferably, the transmission mechanism 1222 is a lever mechanism.

[0091] As for the improvement of the stirring mechanism, according to the second exemplary aspect of the present invention, a feeding box 1 for a washing device 100 is provided, comprising: a liquid storage chamber 11 for receiving feeding, the liquid storage chamber 11 having a discharge port 111; a discharge door mechanism 12, the discharge door mechanism 12 comprising a discharge door 121 for opening and closing the discharge port 111; and a stirring mechanism 13 for stirring the liquid in the liquid storage chamber 11, the stirring mechanism 13 being configured as a magnetic stirring mechanism, the magnetic stirring mechanism having a magnetic stirring structure 131 located in the liquid storage chamber 11 and a magnetic drive device 132 located outside the liquid storage chamber 11 and capable of driving the magnetic stirring structure 131 by means of a magnetic force across the wall of the liquid storage chamber 11.

[0092] like Figure 3 and Figure 4As shown, according to an exemplary embodiment of the present invention, the stirring mechanism 13 is arranged at the bottom wall 112 of the liquid storage chamber 11, and the magnetic stirring structure 131 and the magnetic drive device 132 are respectively located on both sides of the bottom wall 112 opposite to each other. No through hole is required in the corresponding area, avoiding possible leakage problems. The arrangement of the stirring mechanism 13 at the bottom is beneficial to the stirring mixing effect, and is also very beneficial for the arrangement of this non-contact magnetic drive mode.

[0093] See in particular Figure 4 According to an exemplary embodiment of the present invention, the magnetic drive device 132 includes a motor 1321 and a magnet 1322 driven to rotate by the motor 1321. The magnet 1322 may be a magnet, and may be fixed to the output shaft of the motor 1321 to rotate with the output shaft. Thus, the magnet 1322 may generate a rotating magnetic field to act on the magnetic stirring structure 131 in the liquid storage chamber 11, so that the magnetic stirring structure 131 follows the movement.

[0094] Those skilled in the art will appreciate that, as an alternative, the magnetic drive device 132 may also include a rotating magnetic field generating device that generates a rotating magnetic field based on alternating current. It will be appreciated that alternating current may be converted from direct current.

[0095] If the magnet is in contact with water for a long time or frequently, its performance will be affected. Moreover, due to the limitation of material properties, it is difficult to construct a structure with good stirring effect if it is constructed only with magnets as the matrix. Figure 4 As shown, according to an exemplary embodiment of the present invention, the magnetic stirring structure 131 includes a magnet 1311 and a stirring body 1312 which seals the magnet 1311 and can rotate together with the magnet 1311 .

[0096] like Figure 4 As shown, according to an exemplary embodiment of the present invention, the stirring body 1312 can be configured as a wheel disc, and has a convex-concave structure 1313, such as a blade, on the side away from the magnetic drive device 132. This can enhance the stirring effect. At this time, the stirring body 1312 is preferably circular.

[0097] As an advantageous embodiment, the agitating body 1312 may embed the magnet 1311 by plastic overmolding.

[0098] According to an exemplary embodiment of the present invention, Figure 4 As shown, the stirring mechanism 13 also includes a groove structure 136 for receiving the magnetic stirring structure 131, and the outer periphery of the magnetic stirring structure 131 and the inner periphery of the groove structure 136 can be relatively slidably matched. This fit can smoothly guide the rotation of the magnetic stirring structure 131. The groove structure 136 is preferably cylindrical.

[0099] like Figure 4 As shown, according to an exemplary embodiment of the present invention, the stirring mechanism 13 further includes a cover 137 for covering the groove structure 136 to constrain the magnetic stirring structure 131 in the groove structure 136, wherein the cover 137 is provided with at least one through hole 1371. Water enters through the through hole 1371 and is stirred by the stirring body 1312.

[0100] According to an exemplary embodiment of the present invention, the groove structure 136 is formed integrally with the wall of the liquid storage chamber 11. In the case where the liquid storage chamber 11 is injection molded, the groove structure 136 can be easily integrally molded on the wall of the liquid storage chamber 11.

[0101] from Figure 3 As can be seen in FIG. 1 , the at least one through hole 1371 includes a plurality of through holes arranged in a petal shape. Such an arrangement of through holes 1371 can promote mixing.

[0102] According to an exemplary embodiment of the present invention, the cover 137 is snap-fastened to the groove structure 136 as a cap.

[0103] According to an exemplary embodiment of the present invention, Figure 3 and Figure 4 As shown, the feeding box 1 comprises a box body 14 and a box lower cover 15, wherein the box body 14 is configured to be embedded in the box lower cover 15, the liquid storage chamber 11 is formed in the box body 14, and the magnetic drive device 132 is fixed on the box lower cover 15. This upper and lower stacking is very advantageous for the arrangement of the magnetic stirring mechanism.

[0104] According to an exemplary embodiment of the present invention, Figure 4 As shown, the magnetic drive device 132 is fixed to the bottom side 151 of the lower cover 15 of the material box away from the material box body 14. In this case, the wall of the material box body 14 and the wall of the lower cover 15 of the material box are separated from the magnetic drive device 132 and the magnetic stirring structure 131, that is, there are two layers of walls. In this area, the wall of the material box body 14 and the wall of the lower cover 15 of the material box are directly attached together.

[0105] like Figure 4 As shown, according to an exemplary embodiment of the present invention, the bottom side 151 is formed with a recess 1511 for accommodating at least a portion of the magnetic drive device 132, and the feeding box 1 also includes a bracket 16 for holding the magnetic drive device 132, the bracket 16 having a preferably laterally cantilevered fixed foot 161, and the fixed foot 161 can be fixed to the outer peripheral edge of the recess 1511 by screws.

[0106] According to an exemplary embodiment of the present invention, Figure 3 As shown, the actuator 1221 can be fixed on the lower cover 15 of the magazine.

[0107] According to an exemplary embodiment of the present invention, the transmission mechanism 1222 , in particular the lever mechanism thereof, is pivotally fixed on the magazine lower cover 15 .

[0108] According to an exemplary embodiment of the present invention, Figure 3 It can be seen that the liquid storage chamber 11 is configured to be open at the top to allow feeding when the feeding box 1 is pulled out.

[0109] Figure 5-Figure 10 Another exemplary embodiment of the feeding box 1 is shown. Specifically, Figure 5 A perspective view of a feeding box 1 according to an exemplary embodiment of the present invention is shown.

[0110] To make it clearer, Figure 6 Shows Figure 5 The three-dimensional exploded view of the feeding box 1 is shown.

[0111] Figure 7 Shows Figure 5 The stereoscopic view of a part of the lower cover 15 of the feeding box 1 and some components and structures located thereon is shown, wherein the actuator 1221 is in a non-working state and the discharge door 121 is in a state capable of opening the discharge port 111.

[0112] Figure 8 Shows Figure 7 The stereoscopic view of the relevant parts shown is in another working state, wherein the actuator 1221 is in the working state, and it enables the discharge door 121 to be in a state capable of closing the discharge port 111 through the transmission mechanism 1222.

[0113] Fig. 9 Shows Figure 5 The liquid storage chamber 11 and the discharge door mechanism 12 of the feeding box 1 are shown in a three-dimensional view from another angle.

[0114] Fig.10 Shows Figure 5 The feeding box 1 shown is a cross-sectional view taken along the discharge port 111 and the discharge door 121 of the liquid storage chamber 11 , wherein the discharge port 111 is closed by the discharge door 121 .

[0115] The above embodiment more clearly illustrates a discharge door mechanism 12. Figure 5-Figure 10 In the exemplary embodiment shown, the actuator 1221 is configured as an electrically driven actuator.

[0116] In particular, the electrically driven actuator may be configured as an electromagnetic linear actuator. The electromagnetic linear actuator may have only two working states: 1) when powered on, its power output portion 1229 extends outward by a certain distance (see Figure 8) to drive the transmission mechanism 1222; 2) when the power is off and not working, the power output unit 1229 retracts (see Figure 7 ), the transmission mechanism 1222 can follow the return. This driving method is simple, but can meet the control objectives of the present invention.

[0117] According to an exemplary embodiment of the present invention, Figure 6 , Figure 7 and Figure 8 As shown, the driving device 122 also includes a holding device 1224 for initially keeping the discharge door 121 in an open state or a closed state. Figure 6 , Figure 7 and Figure 8 In the illustrated embodiment, the retaining device 1224 is a tension spring and has a tendency to pull the discharge door 121 away from the discharge port 111, so that when the electromagnetic linear drive is powered off and its power output part 1229 retracts, the discharge port 111 can be opened. When powered on, its power output part 1229 needs to overcome the pulling force of the retaining device 1224 to move the discharge door 121 to the discharge port 111.

[0118] Figure 5-Figure 10 The focus is on an implementation of the discharge door mechanism 12. Although it has been mentioned above, we come to the third exemplary aspect of the present invention, which provides a feeding box 1 for a washing device 100, including: a liquid storage chamber 11 for receiving feeding, the liquid storage chamber 11 having a discharge port 111; and a discharge door mechanism 12, the discharge door mechanism 12 including a discharge door 121 for opening and closing the discharge port 111 and configured to at least be able to actively control the discharge door 121 to open.

[0119] In particular, Figure 6 As shown, according to an exemplary embodiment of the present invention, the lower cover 15 of the material box has a lower cover chamber 152 for receiving the liquid discharged from the discharge port 111 when the discharge door 121 is opened, the material box body 14 is configured to be suitable for being embedded in the lower cover chamber 152, and at least a part of the driving device 122 is arranged on the lower cover 15 of the material box. Here, it should be pointed out that the lower cover chamber 152 can be understood as an inner cavity area in the lower cover 15 of the material box that can contact the liquid discharged from the discharge port 111.

[0120] According to an exemplary embodiment of the present invention, Figure 7 and Figure 8 As shown, the transmission mechanism 1222 is arranged in the lower cover chamber 152.

[0121] According to an exemplary embodiment of the present invention, in particular Figure 6 , Figure 7 and Figure 8As shown, the lever mechanism of the transmission mechanism 1222 includes a lever 1225 having a door holding end 1226 for holding the discharge door 121 and a driving end 1227 for receiving an actuating action stimulated by the actuator 1221 .

[0122] According to an exemplary embodiment of the present invention, the lever 1225 is held by a pivot structure 1228 disposed on the lower cover chamber 152 so as to be rotatable.

[0123] like Figure 7 and Figure 8 As shown, according to an exemplary embodiment of the present invention, the lever 1225 is retained on the bottom wall of the lower cover chamber 152 .

[0124] According to an exemplary embodiment of the present invention, Figure 5 As shown, the main body of the actuator 1221 is arranged outside the lower cover chamber 152, and the power output part 1229 of the actuator 1221 sealably passes through the wall of the lower cover chamber 152 and can act on the transmission mechanism 1222. The main body of the actuator 1221 can be the live part of the actuator 1221 when it is working.

[0125] According to an exemplary embodiment of the present invention, in particular Figure 6 , Figure 7 and Figure 8 As shown, the pivot structure 1228 is configured to make the door holding end 1226 and the driving end 1227 rotate in opposite directions. At this time, the pivot structure 1228 can be arranged in the middle area of ​​the lever 1225.

[0126] According to an exemplary embodiment of the present invention, the pivot structure 1228 is configured as a pivot shaft, and the lever 1225 can be mounted on the pivot shaft.

[0127] According to an exemplary embodiment of the present invention, Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the lower cover 15 of the magazine has a platform structure 153 formed on the outside of the lower cover chamber 152 , and the actuator 1221 is fixed on the platform structure 153 .

[0128] It can be clearly seen from the figure that the platform structure 153 is arranged at a corner of the lower cover chamber 152. In addition, relative to the lower cover 15 of the magazine, the platform structure 153 is also arranged at a corner of the lower cover 15 of the magazine.

[0129] The platform structure 153 may extend laterally outward from the outer side of the wall of the lower cover chamber 152 , and the top is not covered by other structures, thereby facilitating the installation of the actuator 1221 .

[0130] According to an exemplary embodiment of the present invention, see Figure 7 and Figure 8 The power output part 1229 is an output shaft of linear motion and directly acts on the driving end 1227 after passing through the side wall of the lower cover chamber 152 .

[0131] like Figure 7 and Figure 8 As shown, according to an exemplary embodiment of the present invention, the pivot shaft is arranged vertically and can be inserted into a retaining structure formed on the bottom wall of the lower cover chamber 152. Figure 7 and Figure 8 As shown, the retaining structure can be a boss that can be integrally formed on the corresponding wall of the lower cover chamber 152.

[0132] Specifically, according to an exemplary embodiment of the present invention, the retaining device 1224, preferably a tension spring, is configured to tension the door retaining end 1226 in a direction away from the discharge port 111. The tension spring is arranged across the corresponding area of ​​the lower cover 15 of the magazine, and another feeding area can be arranged above the area.

[0133] According to an exemplary embodiment of the present invention, the actuator 1221 is configured to only be able to push the transmission mechanism 1222. In this case, the actuator 1221 does not need to be connected to the transmission mechanism 1222.

[0134] Although a possible working mode of the actuator may be mentioned above, for the sake of clarity, according to an exemplary embodiment of the present invention, the actuator 1221 drives the transmission mechanism 1222 to close the discharge door 121 in the working state, and keeps the discharge door 121 in the open state through the retaining device 1224 in the non-working state. Therefore, the discharge door 121 can be actively closed by the actuator 1221 only when the discharge door 121 needs to be closed.

[0135] Next, let's look at another possible implementation according to the third exemplary aspect of the present invention.

[0136] Fig.11 A perspective exploded view of a feeding box 1 according to an exemplary embodiment of this aspect of the invention is shown.

[0137] Fig.12 Shows Fig.11 The feeding box 1 shown is a three-dimensional view observed from an oblique upper angle in the assembled state, wherein relative to Fig.11 , some parts have been removed.

[0138] Fig.13 Shows Fig.12The bottom cover 15 of the feeding box 1 and the transmission mechanism 1222 located thereon and the three-dimensional view of the related structure, wherein relative to Fig.12 Some parts have been removed. It can be seen that the transmission mechanism 122 is also a lever mechanism at this time.

[0139] Fig.14 Shows Fig.11 and Fig.13 A three-dimensional view of the transmission mechanism 1222 and the discharge door 121 of the feeding box 1 is shown.

[0140] Fig.15 Shows Fig.12 The feeding box 1 shown is a three-dimensional cross-sectional view taken along a section (in the width direction) passing through the actuating box 1223.

[0141] Fig.16 Shows Fig.12 The feeding box 1 shown is a cross-sectional view taken along another cross-section (longitudinal direction) through the transmission mechanism 1222.

[0142] According to an exemplary embodiment of the present invention, the actuator 1221 is configured as a water-driven actuator. Fig.11 In the illustrated embodiment, the water-driven actuator includes an actuation box 1223 for receiving water to be displaced to actuate the transmission mechanism 1222. The actuation box 1223 may be substantially square in shape.

[0143] Those skilled in the art will appreciate that when the actuation box 1223 is filled with water, it will sink as the weight increases, which can actuate the transmission mechanism 1222 .

[0144] In this case, according to an exemplary embodiment of the present invention, the actuator 1221 and the transmission mechanism 1222 may both be arranged in the lower cover chamber 152 , because in this case, there is no need to consider the electrical insulation sealing problem of the actuator 1221 .

[0145] As can be seen from the figure, according to an exemplary embodiment of the present invention, the top of the actuating box 1223 is open. This facilitates filling with water from above.

[0146] According to an exemplary embodiment of the present invention, in particular Fig.13 and Fig.15 As shown, the actuating box 1223 is movably, especially vertically movably, embedded in a retaining frame 1521 in the lower cover chamber 152 .

[0147] According to an exemplary embodiment of the present invention, in particular Fig.13 and Fig.15 As shown, the driving end 1227 of the transmission mechanism 1222 is arranged below the actuating box 1223.

[0148] According to an exemplary embodiment of the present invention, Fig.15 As shown, the bottom of the actuating box 1223 is provided with a leakage hole 1230 for draining water into the lower cover chamber 152. The water in the actuating box 1223 can leak into the lower cover chamber 152 through the leakage hole 1230, so that the actuating box 1223 can be returned to its original position with the help of the retaining device 1224, so as to prepare for the next water filling sinking drive transmission mechanism 1222.

[0149] like Fig.13 As shown, according to an exemplary embodiment of the present invention, the retaining frame 1521 is provided with a lateral opening 1523 through which the transmission mechanism 1222 can pass.

[0150] According to an exemplary embodiment of the present invention, the actuator box 1223 is removably embedded in the holder 1521. For example, it can be removed from the holder 1521.

[0151] like Fig.15 As shown, according to an exemplary embodiment of the present invention, the bottom of the actuator box 1223 is configured in a step shape, and the leakage hole 1230 is set at the lowest point. The step is in the shape of a platform, and the leakage hole 1230 is set on the lowest platform. The water that will eventually flow out of the leakage hole 1230 will gather at the lowest area, and the lever principle can be used to return the actuator box 1223 to the normal position, so as to release the pushing effect on the transmission mechanism 1222 after the water flows out of the leakage hole 1230.

[0152] According to an exemplary embodiment of the present invention, the bottom of the actuating box 1223 includes a protrusion 1231 that acts on the transmission mechanism 1222. In this way, the transmission mechanism 1222 can be driven by concentrated force.

[0153] See in particular Fig.14 According to an exemplary embodiment of the present invention, the pivot structure 1228 is configured to make the door holding end 1226 and the driving end 1227 rotate in the same direction. This is different from the above-mentioned embodiment.

[0154] According to an exemplary embodiment of the present invention, the actuator box 1223 is integrally formed, for example, by injection molding.

[0155] Especially if Fig.13 As shown, the pivot structure 1228 includes a lateral opening 1232 (at Fig.13 The lever 1225 is inserted into the retaining channel through the lateral opening 1232. For example, the lateral opening is opened by squeezing and loading.

[0156] like Fig.13 , Fig.14 and Fig.15As shown, the lever mechanism 1222 further includes a toggle piece 1233 extending laterally at the driving end 1227, and the actuator 1221, in particular the protrusion 1231, acts on the toggle piece 1233. The protrusion 1231 can act on the end of the toggle piece 1233 to enhance the lever action.

[0157] Especially if Fig.14 As shown, according to an exemplary embodiment of the present invention, the lever 1225 has a narrowing section 1234 at a position corresponding to the pivot structure 1228 to limit the axial movement of the lever 1225. That is, in the assembled state, the narrowing section 1234 is clamped in the holding channel of the pivot structure 1228.

[0158] According to an exemplary embodiment of the present invention, the discharge door 121 and the toggle piece 1233 extend from the same side of the lever 1225 .

[0159] Especially if Fig.13 and Fig.15 As shown, according to an exemplary embodiment of the present invention, the lower cover chamber 152 is further provided with a limiting structure 1522 adjacent to the driving end 1227 for limiting the retaining device 1224 .

[0160] Especially Fig.13 and Fig.15 As shown, according to an exemplary embodiment of the present invention, the lower cover chamber 152 is further provided with a stop structure 1523 below the actuating box 1223 for limiting the maximum extent of the downward movement of the actuating box 1223 .

[0161] Preferably, the limiting structure 1522 and / or the stop structure 1523 are configured as plate-like structures protruding upward from the bottom of the lower cover chamber 152. They can be integrally formed on the lower cover chamber 152. The lower cover 15 of the material box can be integrally formed.

[0162] Especially if Fig.13 and Fig.15 As shown, the limiting structure 1522 and the stopping structure 1523 are arranged parallel to each other.

[0164] In this exemplary embodiment, the drain port 111 is provided at the bottom of the liquid storage chamber 11 .

[0165] Similarly, the actuation box 1223 is also configured to only be able to push the transmission mechanism 1222 .

[0166] Although the corresponding working principles or working processes may have been mentioned or implied above, for the sake of clarity, according to an exemplary embodiment of the present invention, the actuating box 1223 drives the transmission mechanism 1222 to open the discharge door 121 when receiving water, and drives the retaining device 1224 to close the discharge door 121 when not receiving water.

[0167] According to an exemplary embodiment of the present invention, Fig.11 As shown, the feeding box 1 further includes a diverter plate 17 for diverting water of the water inlet system of the washing device 100 into the liquid storage chamber 11 from above.

[0168] Also like Fig.11 As shown, the feeding box 1 further comprises a box cover 18 , which is provided with at least one first water inlet 181 for supplying water to the liquid storage chamber 11 and a second water inlet 182 for supplying water to the actuating box 1223 .

[0169] According to an exemplary embodiment of the present invention, in particular Fig.11 As shown, the diverter plate 17 is arranged below the upper cover 18 of the material box.

[0170] Especially if Fig.11 As shown, the at least one first water inlet 181 includes two first water inlets 181 that supply water to different areas of the diverter plate 17 respectively.

[0171] To strengthen the seal, Fig.14 As shown, the discharge door 121 is provided with a sealing member 1211 for sealingly engaging with the edge of the discharge port 111. For other embodiments described above, for example Fig.10 As shown, a corresponding seal 1211 is also provided.

[0172] for Figure 11-Figure 16 In the illustrated embodiment, the actuator 1221 may be disposed at the outer end of the pull-out structure.

[0173] like Figure 17-Figure 21 As shown, according to a fourth exemplary aspect of the present invention, there is provided a feeding box 1 for a washing device 100, comprising: a liquid storage chamber 11 for receiving feeding, the liquid storage chamber 11 having a discharge port 111; a discharge door mechanism 12, the discharge door mechanism 12 comprising a discharge door 121 for opening and closing the discharge port 111; and a stirring mechanism 13 for stirring the liquid in the liquid storage chamber 11, the stirring mechanism 13 being configured as a pneumatic stirring mechanism, the pneumatic stirring mechanism comprising an airflow generating device 133 for generating an airflow and a drainage device 134 for introducing the airflow into the liquid in the liquid storage chamber 11.

[0174] It can be understood that the airflow generating device 133 can be any device capable of generating airflow, such as a compressor and a fan.

[0175] Specifically, Fig.17 A perspective view of a feeding box 1 according to an exemplary embodiment of the present invention is shown.

[0176] Fig.18 Shows Fig.17 The cross-sectional view of the feeding box 1 is shown, wherein the airflow generating device 133 is in a connected state.

[0177] Fig.19 Shows Fig.17 The cross-sectional view of the feeding box 1 is shown, wherein the airflow generating device 133 is in a disconnected state.

[0178] Fig. 20 Shows Fig.17 The cross-sectional view of the feed box 1 shown is a part of the diverter plate 17 for diverting the water supply into the liquid storage chamber 11 and the pneumatic stirring mechanism 13 .

[0179] Fig.21 Shows Fig.17 The feeding box 1 shown in FIG. Fig. 20 A top view of the structure shown.

[0180] According to an exemplary embodiment of the present invention, Fig.18 , Fig.19 and Fig.21 As shown, the pneumatic stirring mechanism further includes an air flow nozzle 135 fluidly connected to the end of the flow guide device 134 , and the air flow nozzle 135 has a plurality of air flow nozzles 1351 .

[0181] According to an exemplary embodiment of the present invention, in particular Fig.18 and Fig.19 As shown, the drainage device 134 includes a first tube segment 1341 fixed in the liquid storage chamber 11 and a second tube segment 1342 fluidically connected to the airflow generating device 133, and the first tube segment 1341 and the second tube segment 1342 are configured to be able to dock or separate through relative movement.

[0182] Especially if Fig.18 and Fig.19 As shown, the first pipe section 1341 is fixed to the wall of the liquid storage chamber 11 through the air flow nozzle 135.

[0183] To facilitate docking and separation, especially Fig.19 As shown, the butted ends 1343 , 1344 of the first pipe section 1341 and the second pipe section 1342 are configured to have slopes that match each other.

[0184] According to an exemplary embodiment of the present invention, in particular Fig.18 and Fig.19 As shown, the first pipe section 1341 is arranged upright.

[0185] like Fig.18 and Fig.19 As shown, the second tube segment 1342 has a main tube segment 1345 , and the docking end 1344 of the second tube segment 1342 is bent relative to the main tube segment 1345 .

[0186] According to an exemplary embodiment of the present invention, Fig.19 As shown, the second pipe section 1342, especially its docking end 1344, is fixed to the diverter plate 17 and extends through the diverter plate 17 into the liquid storage chamber 11.

[0187] In order to avoid causing excessive water splashes, the air flow nozzle 135 is configured to enable the air flow to flow out from the air flow nozzle 1351 along the bottom wall of the liquid storage chamber 11 .

[0188] like Fig.21 As shown, the plurality of air flow nozzles 1351 are evenly distributed in the circumferential direction. Fig.21 Only two air flow nozzles 1351 are shown in the figure. It can be understood that more air flow nozzles 1351 can be provided in practice to enhance the mixing effect.

[0189] from Fig.18 and Fig.19 As can be seen in the figure, the diameter of the airflow nozzle 135 is larger than the diameter of the first tube section 1341 and together with the bottom wall of the liquid storage chamber 11, a cavity 1352 is enclosed, and the airflow nozzle 1351 is laterally connected to the cavity 1352. The cavity 1352 is preferably flat.

[0190] Preferably, the air flow nozzle 135 is configured to generate a vortex in the liquid in the liquid storage chamber 11. For example, a plurality of air flow nozzles 1351 may be arranged in a vortex.

[0191] As an advantageous docking and separation method, the feeding box 1 is configured to enable the first pipe section 1341 to automatically dock with the second pipe section 1342 by a pushing operation, especially when the feeding box 1 is configured as a pull-out structure.

[0192] Other possible implementations of the driving device 122 are described below.

[0193] Fig. 22 A perspective view of a feeding box 1 according to another embodiment of the present invention is shown.

[0194] Fig.23 Shows Fig. 22 A three-dimensional view of a portion of the feeding box 1 is shown to better illustrate the driving device 22.

[0195] Fig.24 Shows Fig. 22 The top view of the material box body 14 of the material feeding box 1 is shown, wherein the discharge door 121 is in an open state.

[0196] Fig.25 Shows Fig.24 The material box body 14 shown is along Fig.24 The cross-sectional view is made along the cutting line BB in FIG. 1 , but the discharge door 121 is in a closed state.

[0197] Fig.26 Shows Fig.24 The material box body 14 shown is along Fig.24 From the cross-sectional view taken along the cutting line BB in FIG. 1 , it can be seen that the discharge door 121 is opened to allow the liquid to flow out, as schematically indicated by the arrow in the figure.

[0198] Since the above description has been made in detail, those skilled in the art can easily understand that the following description will focus on the differences or key parts.

[0199] exist Figure 22-26 In the embodiment shown, the actuator 1221 is configured as a rotary motor. Accordingly, the transmission mechanism 1222 can be configured as a gear rack mechanism, such as Fig.23 As shown, the rack-and-pinion mechanism includes a gear connected to the output shaft of the rotating motor and a rack meshed with the gear, and the rack acts on the discharge door 121. Here, it presses on the discharge door 121 from below.

[0200] like Fig.23 As shown, especially in combination Fig.25 and Fig.26 It can be seen that according to an exemplary embodiment of the present invention, the discharge door 121 is pivotally held on the liquid storage chamber 11 and has a convex edge 1212 extending outward, and the rack acts on the convex edge 1212 to open the discharge door 121 by pushing the convex edge 1212. In the figure, the rack presses against the lower side of the convex edge 1212 from below.

[0201] At this time, the pivoting installation part of the discharge door 121 is located in the middle of the discharge door 121. Therefore, when the convex edge 1212 is pushed upward by the rack, the convex edge 1212 will slightly deflect toward the inside of the liquid storage chamber 11, and the other end will deflect outward, thereby opening the discharge port 111. This point can be seen in Fig.26Therefore, the actuator 1221, i.e., the rotary motor, drives the transmission mechanism 1222 in the working state to open the discharge door 121, and in the non-working state, the discharge door 121 is closed by the retaining device 1224. Of course, if necessary, the rotary motor needs to rotate in the opposite direction after opening the discharge door 121 in order to close the discharge door 121 again, so as to allow the retaining device 1224 to return the discharge door 121 to the closed state.

[0202] like Fig.23 As shown, according to an exemplary embodiment of the present invention, the convex edge 1212 constitutes a part of the upper edge of the liquid storage chamber 11. It can also be seen from the figure that the rack is arranged upright.

[0203] According to an exemplary embodiment of the present invention, Fig.23 As shown, the retaining device 1224 is configured as a damping shaft, and the discharge door 121 is retained on a boss extending from the outside of the liquid storage chamber 11 by the damping shaft. The damping shaft itself is well known and has a certain reset force. Here, for the sake of simplicity, it is not repeated.

[0204] Figure 27-Figure 31 Another embodiment of the drive device 122 is shown. Specifically, Fig. 27 A top view of a feeding box 1 according to an exemplary embodiment of the present invention is shown. Fig.28 Shows Fig. 27 The three-dimensional exploded view of the feeding box 1 is shown. Fig.29 Shown along Fig. 27 The sectional view is made along the cutting line CC in FIG. 4 . For the convenience of understanding, the sectional view is rotated and flipped here. Fig.30 A perspective view is shown in the region of the drive device 122 . Fig.31 Shows Fig.30 Another operating state of the drive device 122 is shown.

[0205] Here, the actuator 1221 is also configured as a rotary motor. However, in particular Fig.30 and Fig.31 As shown, the transmission mechanism 1222 is configured as a cam mechanism, which includes a cam connected to the output shaft of the rotary motor, and a coupling structure 1213 cooperating with the cam is provided on the discharge door 121. In this case, the cam can drive the discharge door 121 by rotating.

[0206] Preferably, the rotary motor is configured as a steering gear. The steering gear is usually composed of a DC motor, a motor controller, a potentiometer and a reducer, etc., and is a servo unit encapsulated in a housing that is easy to install. It is a motor system that can rotate a given angle more accurately using a simple input signal. The steering gear is equipped with a potentiometer (or angle sensor) to detect the rotation angle of the output shaft. The control board controls and adjusts the angle of the output shaft according to the information of the potentiometer (or angle sensor), forming a closed-loop control system.

[0207] In order to cooperate with the cam mechanism, the discharge door 121 is preferably held on the liquid storage chamber 11 so as to be movable up and down.

[0208] For this reason, especially Fig.30 and Fig.31 As shown, the engagement structure 1213 includes an upper engagement structure provided at the upper end of the discharge door 121 and a lower engagement structure opposite to the upper engagement structure, and the cam is arranged between the upper engagement structure and the lower engagement structure. By rotating the cam, the discharge door 121 can be brought to an upper position and a lower position. As described above, since the angle of the servo can be accurately controlled, the discharge door 121 can be kept in an upper position or a lower position as required. The discharge door 121 can be switched on and off once every 180 degree rotation of the servo.

[0209] In order to increase reliability, the cam is configured as a double-layer cam. In this case, at least one of the upper and lower positions, the double-layer cam contacts the corresponding part of the upper engaging structure or the lower engaging structure. Here, as an example, the double-layer cam contacts the upper engaging structure at Fig.31 In the state of contact, this can also be seen by comparing Fig.30 To this end, the upper engagement structure is configured as a step, such as Fig.30 shown.

[0210] Preferably, the double-layer cam is a double-layer concentric cam.

[0211] According to an exemplary embodiment of the present invention, the cam is engaged with the upper engagement structure to open the discharge door 121 , and the cam is engaged with the lower engagement structure to close the discharge door 121 .

[0212] To fix a rotating electrical machine, such as Fig.28 As shown, the feeding box 1 also includes a fixed cover 124 for fixing the rotating motor. The fixed cover 124 can be fixed on the outer side of the lower cover 15 of the feeding box.

[0213] According to an exemplary embodiment of the present invention, the feeding box 1 may be configured to be allowed to be pulled out only when the discharge door 121 is closed.

[0214] According to an exemplary embodiment of the present invention, the feeding box 1 is configured such that the discharge door 121 is always in a closed state when the feeding box 1 is pulled out.

[0215] Therefore, it can be ensured that, on the one hand, the user is not allowed to perform adding operations when the discharge door 121 is opened, and on the other hand, after opening, the liquid material added by the user will not flow out of the liquid storage chamber 11 by itself.

[0216] exist Figure 22-Figure 31 In the illustrated embodiment, the driving device generates an up-and-down force on the discharge door 121, which will not cause the feeding box to pop out accidentally.

[0217] The above mainly describes the feeding box 1 with respect to the key parts of the present invention, and other aspects are not described in detail. For example, as shown in the figure, the feeding box 1 can have multiple feeding areas, wherein the liquid storage chamber 11 corresponds to one feeding area. The present invention does not impose any limitation on these, and therefore will not be described in more detail.

[0218] According to a fifth exemplary aspect of the present invention, a washing device 100, in particular a drum washing machine, is provided, comprising: a feed box 1 for the washing device 100 according to any of the above embodiments; and a water inlet system, wherein the feed box 1 is connected in series to the water inlet system to allow water to flow through the feed box 1. The water inlet system includes corresponding water channels.

[0219] According to a sixth exemplary aspect of the present invention, there is provided a method for operating the above-mentioned washing device 100, the method comprising: supplying water to a liquid storage chamber 11 in which materials are placed through a water inlet system when a discharge door 121 is closed; stirring the liquid in the liquid storage chamber 11 through a stirring mechanism 13; and opening the discharge door 121 to allow the liquid in the liquid storage chamber 11 to flow into a washing drum of the washing device 100.

[0220] According to an exemplary embodiment of the present invention, after the stirring mechanism 13 stirs for a predetermined time, the discharge door 121 is opened. The predetermined time can be determined according to the dissolution characteristics or mixing characteristics of the feed.

[0221] According to an exemplary embodiment of the present invention, the method further comprises: while and / or after the liquid in the liquid storage chamber 11 flows into the washing tub, preferably supplying water to the liquid storage chamber 11 through a water inlet system to flush the liquid storage chamber 11. Of course, the lower cover chamber 152 and the corresponding downstream waterway may also be flushed.

[0222] for Figure 11-Figure 16In the embodiment shown, during and after the liquid in the liquid storage chamber 11 is discharged from the discharge port 111, water (usually clean water) in the actuating box 1223 can leak into the lower cover chamber 152 through the leakage hole 1230 to flush it. Since the leakage hole 1230 is relatively small, the lower cover chamber 152 can be continuously flushed for a period of time after the liquid in the liquid storage chamber 11 is discharged from the discharge port 111. This flushing can also help clean the downstream waterway to minimize the residual feed in the waterway.
