[0045] DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0047] It should be noted that all directional indications, such as upper, lower, left, right, front, back, under, over, upper, lower, left, right, front, back, etc., are intended to facilitate the understanding of the relative position relationship, movement condition, etc. between various components, and if the specific posture changes, the directional indications will also change accordingly.

[0048] In the present application, unless otherwise explicitly specified and limited, the terms "connection", "fixation" and the like should be understood in a broad sense, for example, "fixation" can be fixed connection, or detachable connection, or integral; can be mechanical connection, or electrical connection; can be direct connection, or indirect connection through intermediate medium; can be internal communication of two elements or interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] In addition, the description involving "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that the technical solutions can be realized by those skilled in the art. When the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the scope of protection claimed in the present application.

[0050] The first aspect of the present application discloses a dispensing device, which is combined with Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown in the drawings, in some embodiments, the dispensing device comprises a frame 1000, a cover 2000, a clamping jaw 3100 and an operating member 3200. The frame 1000 can be understood as the main part of the dispensing device, and the frame 1000 is provided with a dispensing opening 1200, more specifically, the frame 1000 is provided with a position for storing detergent, such as a containing cavity 1100, which forms a dispensing opening 1200. Through the dispensing opening 1200, the detergent can be placed into the containing cavity 1100, and the detergent can also be dispensed out of the containing cavity 1100 through the dispensing opening 1200 (to the washing cavity). The detergent can be a solid detergent, such as dishwashing powder, dishwashing block, etc. Of course, the detergent can also be other types of detergent.

[0051] The pouring opening 1200 needs to cooperate with the cover 2000, and the cover 2000 is used to open and close the pouring opening 1200, that is, the cover 2000 can both open and close the pouring opening 1200. It can be understood that the cover 2000 needs to be opened to the pouring opening 1200 before the detergent is placed into the containing cavity 1100, and the cover 2000 needs to be closed to the pouring opening 1200 after the detergent is placed into the containing cavity 1100 and before the pouring. When the detergent needs to be poured during the use of the pouring device, the cover 2000 needs to be opened to the pouring opening 1200.

[0052] The cover 2000 needs to cooperate with the pawl 3100 to close and open the pouring opening 1200. When the cover 2000 is in the state of closing the pouring opening 1200, the pawl 3100 locks the cover 2000, that is, a constraint is generated between the pawl 3100 and the cover 2000, so that the state of the cover 2000 closing the pouring opening 1200 is maintained. When the pawl 3100 unlocks the cover 2000, the cover 2000 can be switched from the state of closing the pouring opening 1200 to the state of opening the pouring opening 1200. The cover 2000 can be switched from the state of closing the pouring opening 1200 to the state of opening the pouring opening 1200 under the action of the elasticity, for example, by arranging a third elastic member (not shown in the figure), the third elastic member is used to generate force on the cover 2000. When the pawl 3100 unlocks the cover 2000, the third elastic member drives the cover 2000 to open the pouring opening 1200.

[0053] The cooperation between the cover 2000 and the pawl 3100 above realizes the closing and opening of the pouring opening 1200, which is similar to related technologies. For specific structures, please refer to related technologies, and no more details are given here.

[0054] The user may repeatedly control the cover 2000 to close and open the pouring opening 1200 each time when the user supplements the detergent into the accommodation cavity 1100. For example, after the user places the detergent into the accommodation cavity 1100 and controls the cover 2000 to close the pouring opening 1200, if the user wants to continue to adjust the amount of the detergent, the user needs to open the cover 2000. Therefore, in the embodiment, the operation member 3200 is arranged to achieve the above purpose. The operation member 3200 is used to drive the pawl 3100 to move, so that the pawl 3100 unlocks the cover 2000. The movement of the pawl 3100 includes but is not limited to rotation, swing, translation, curved motion, straight reciprocating motion or compound motion (such as rotation first and then translation), and the like. For example, in the embodiment, the pawl 3100 is unlocked by rotating the cover 2000, which can not only ensure the locking of the cover 2000, but also reduce the unlocking resistance. The user can manually operate the operation member 3200, so that the operation member 3200 drives the pawl 3100 to move, and the pawl 3100 is unlocked, so that the cover 2000 opens the pouring opening 1200, and the user can adjust the amount of the detergent. When the adjustment is completed, the user can control the cover 2000 to close the pouring opening 1200. Alternatively, the operation member 3200 is arranged on the frame 1000 and is movable relative to the frame 1000. When the user operates the operation member 3200 to drive the pawl 3100 to move, no force is directly generated on the cover 2000 to interfere with the movement (opening of the pouring opening 1200) of the cover 2000. Therefore, the cover 2000 can be more smoothly opened to open the pouring opening 1200, and the operation experience is improved.

[0055] In combination Figure 2 As shown in the drawings, in some embodiments, the pouring device is arranged on the door body of the washing appliance. When the door body of the washing appliance is opened and the door body is in a flat state, the cover 2000 is located on the top surface of the pouring device, and the operation member 3200 is located on the side surface of the pouring device. The washing appliance has a washing cavity, and the door body can close the washing cavity and open the washing cavity. When the door body opens the washing cavity, the door body is generally in a flat state. At this time, the cover 2000 is located on the top surface of the pouring device, and the operation member 3200 is located on the side surface of the pouring device. The operation member 3200 and the cover 2000 are arranged on different surfaces, which is beneficial to the arrangement of the structure and makes full use of the structure space. Generally, the user stands around the door body. Arranging the operation member 3200 on the side surface of the pouring device is more beneficial to the operation of the user. The operation member 3200 is located on the top surface of the pouring device. When the cover 2000 is opened, the pouring opening 1200 is exposed, which is convenient for adding the detergent.

[0056] In combination Figure 2As shown, in some embodiments, the operation member 3200 is configured to be pressable so as to drive the clamping jaw 3100 to move, the user can press the operation member 3200 so that the operation member 3200 drives the clamping jaw 3100 to move, thereby unlocking the cover 2000 by the clamping jaw 3100, the pressing operation is easier for the user to exert force on the operation member 3200, the pressing direction is basically the same as the moving direction of the operation member 3200 under the pressing action, and the relative sliding between the user's finger and the operation member 3200 is not easy to occur, which is easier for the user to drive the operation member 3200 to move.

[0057] On the basis of the pressable configuration of the operation member 3200, the operation member 3200 and the clamping jaw 3100 are matched to realize the movement of the clamping jaw 3100 in the form of rotation, as shown in Figure 7 , Figure 8 and Figure 13 As shown, the pressing direction of the operation member 3200 is the first direction, the operation member 3200 is provided with a first abutting surface 3210, the clamping jaw 3100 is provided with a second abutting surface 3110, the first abutting surface 3210 and the second abutting surface 3110 are obliquely arranged relative to the first direction, and the first abutting surface 3210 is adapted to abut against the second abutting surface 3110 when the operation member 3200 is pressed so as to drive the clamping jaw 3100 to rotate, that is, when the user presses the operation member 3200 along the first direction to move the operation member 3200, the first abutting surface 3210 contacts the second abutting surface 3110, and since the first abutting surface 3210 and the second abutting surface 3110 are obliquely arranged relative to the first direction, for example, the first abutting surface 3210 and the second abutting surface 3110 are parallel at the moment of contact and oblique relative to the first direction, in this way, the force generated by the operation member 3200 on the clamping jaw 3100 generates a component force in the direction perpendicular to the second abutting surface 3110, which can drive the clamping jaw 3100 to rotate.

[0058] Further, as shown in Figure 3 The device further comprises a driving mechanism 4000 for driving the clamping jaw 3100 to move, so as to unlock the cover 2000 by the clamping jaw 3100, the driving mechanism 4000 is a component capable of outputting power, and the automatic opening of the cover 2000 can be realized by the arrangement of the driving mechanism 4000.

[0059] For example, the dispensing device is applied to a washing appliance, including but not limited to a dishwasher, a washing machine, etc. Before starting the washing appliance, the pawl 3100 is driven by the operating member 3200 to move, so that the cover 2000 opens the dispensing opening 1200 (if the cover 2000 has already opened the dispensing opening 1200, this step can be skipped). The user can place the detergent into the accommodation cavity 1100. After placing the detergent into the accommodation cavity 1100, the cover 2000 is controlled to close the dispensing opening 1200. If the amount of the detergent is to be adjusted again after the cover 2000 closes the dispensing opening 1200, the pawl 3100 is driven by the operating member 3200 to move, so that the cover 2000 opens the dispensing opening 1200. After the amount of the detergent is adjusted, the cover 2000 is controlled to close the dispensing opening 1200. After starting the washing appliance, at a certain stage of washing, the pawl 3100 is driven by the driving mechanism 4000 to move, so that the pawl 3100 drives the cover 2000 to open the dispensing opening 1200. The detergent can be separated from the accommodation cavity 1100 and be dispensed from the dispensing opening 1200 (e.g. under the action of gravity) into the washing cavity. After the washing appliance is stopped (at this time, the cover 2000 is already in the state of opening the dispensing opening 1200) and before the washing appliance is used next time, the detergent needs to be replenished into the accommodation cavity 1100.

[0060] It can be understood that the driving mechanism 4000 has various forms. For example, the driving mechanism 4000 is in the form of electric driving. For another example, the driving mechanism 4000 includes a power source 4001 and a transmission assembly 4002. The power source 4001 can be an electric motor. The transmission assembly 4002 can be a gear transmission or a link transmission, etc. This document does not list them one by one.

[0061] In combination with Figures 4 to 9 As shown in FIG. 8, in some embodiments, the dispensing device further includes a rotating shaft 3300. The pawl 3100 is arranged on the rotating shaft 3300. The driving mechanism 4000 is adapted to be connected with the rotating shaft 3300 to drive the rotating shaft 3300 to rotate. The pawl 3100 is adapted to rotate when the rotating shaft 3300 rotates to unlock the cover 2000. The driving mechanism 4000 drives the pawl 3100 to move, which specifically means that the driving mechanism 4000 drives the rotating shaft 3300 to rotate, so that the rotating shaft 3300 drives the pawl 3100 to rotate. The pawl 3100 rotates to unlock the cover 2000, so that the detergent is dispensed. Through the arrangement of the rotating shaft 3300, the pawl 3100 can be away from the driving mechanism 4000, which is more convenient for the arrangement of the structure.

[0062] In combination with Figure 10 and Figure 11As shown, in some embodiments, the clamping jaw 3100 is sleeved on the rotating shaft 3300, the circumferential wall of the rotating shaft 3300 is provided with a clamping protrusion 3310, the clamping jaw 3100 is provided with a gap 3120, the clamping protrusion 3310 is suitable for clamping into the gap 3120 so that the rotating shaft 3300 can drive the clamping jaw 3100 to rotate, by such arrangement, the complexity of the cooperation between the rotating shaft 3300 and the clamping jaw 3100 is reduced, which is conducive to simplifying the structure. Specifically, the clamping protrusion 3310 clamps into the gap 3120, when the rotating shaft 3300 rotates, along the rotating direction of the rotating shaft 3300, the clamping protrusion 3310 abuts against the wall of the gap 3120, so that the clamping jaw 3100 can be driven to rotate, thereby opening the cover body 2000.

[0063] From the above, the clamping jaw 3100 can also be driven to rotate by the operating member 3200 to open the cover body 2000, in order to avoid interference between the clamping jaw 3100 driven to rotate by the operating member 3200 and the clamping jaw 3100 driven to rotate by the driving mechanism 4000, in the present embodiment, the included angle between the two sides of the clamping protrusion 3310 is smaller than the included angle between the two sides of the gap 3120 along the circumferential direction of the rotating shaft 3300 (which can be understood as the rotating direction), that is, there is a gap between the clamping protrusion 3310 and the wall of the gap 3120. For example Figure 12 As shown, the included angle between the two sides of the clamping protrusion 3310 is L1, the included angle between the two sides of the gap 3120 is L2, L2 is greater than L1, and in the present embodiment, L2 is three times L1. Assuming that one side wall of the clamping protrusion 3310 and the gap 3120 abuts, if the rotating shaft 3300 rotates, the clamping protrusion 3310 can act on one side wall of the gap 3120, thereby driving the clamping jaw 3100 to rotate, if the rotating shaft 3300 does not move and the clamping jaw 3100 is driven to rotate by the operating member 3200 (the rotating direction is the same as that of the rotating shaft 3300 driving the clamping jaw 3100 to rotate), at this time, one side wall of the gap 3120 gradually moves away from the clamping protrusion 3310, and the other side wall of the gap 3120 gradually approaches the clamping protrusion 3310, so that the clamping jaw 3100 unlocks the cover body 2000 and the rotation of the clamping jaw 3100 does not interfere with the rotating shaft 3300 (the driving mechanism 4000).

[0064] In combination Figure 10 and Figure 11 As shown, in some embodiments, the clamping jaw 3100 is suitable for reciprocating along the rotating shaft 3300 between a third position and a fourth position; at the third position, the clamping protrusion 3310 clamps into the gap 3120; at the fourth position, the clamping protrusion 3310 and the gap 3120 are separated so that the clamping jaw 3100 and the rotating shaft 3300 can rotate relative to each other.

[0065] The clamping jaw 3100 is movably connected with the rotating shaft 3300, and the clamping jaw 3100 can move to a third position and a fourth position along the rotating shaft 3300. The third position and the fourth position are limit positions of reciprocating movement of the clamping jaw 3100. When the clamping jaw 3100 is in the third position, the clamping protrusion 3310 is clamped into the gap 3120 at this time. In this case, the rotating shaft 3300 can drive the clamping jaw 3100 to rotate, and the operating member 3200 can drive the clamping jaw 3100 to rotate. When the clamping jaw 3100 is in the fourth position, the clamping protrusion 3310 is separated from the gap 3120 at this time. When the rotating shaft 3300 rotates, the clamping protrusion 3310 no longer abuts against the wall of the gap 3120 along the rotating direction of the rotating shaft 3300. Thus, the rotating shaft 3300 can no longer drive the clamping jaw 3100 to rotate, that is, the rotating shaft 3300 and the clamping jaw 3100 can rotate relative to each other.

[0066] The driving mechanism 4000 is adapted to drive the rotating shaft 3300 to rotate to drive the clamping jaw 3100 to rotate when the clamping jaw 3100 is in the third position. The operating member 3200 is also adapted to drive the clamping jaw 3100 to rotate when the clamping jaw 3100 is in the third position. The clamping jaw 3100 is adapted to switch from the third position to the fourth position after the cover 2000 is unlocked. That is, before the washing appliance is started and after the user supplements the detergent, the cover 2000 is in a position of closing the pouring opening 1200, and at this time, the clamping jaw 3100 is in the third position. During use of the washing appliance and when the detergent needs to be poured, the driving mechanism 4000 drives the rotating shaft 3300 to rotate, and the rotating shaft 3300 drives the clamping jaw 3100 to rotate, so that the clamping jaw 3100 unlocks the cover 2000. In this embodiment, the clamping jaw 3100 is adapted to switch from the third position to the fourth position after the cover 2000 is unlocked, that is, after the rotating shaft 3300 drives the clamping jaw 3100 to rotate by a certain angle, the clamping jaw 3100 unlocks the cover 2000, the cover 2000 opens the pouring opening 1200, and the clamping jaw 3100 needs to switch from the third position to the fourth position. If the driving mechanism 4000 continues to control the rotating shaft 3300 to rotate subsequently, the rotating shaft 3300 can no longer drive the clamping jaw 3100 to rotate. Thus, the driving mechanism 4000 can continue to perform other actions without affecting the clamping jaw 3100.

[0067] The movement of the clamping jaw 3100 from the third position to the fourth position can be achieved by the first elastic member 3410. In combination with Figure 4 、 Figure 5 、 Figure 6 and Figure 9As shown, in some embodiments, the dispensing device further comprises a first elastic member 3410 adapted to generate a force on the pawl 3100 to drive the pawl 3100 to switch from the third position to the fourth position after the pawl 3100 unlocks the cover 2000. That is, when the pawl 3100 is in the third position, the first elastic member 3410 is elastically deformed and accumulates elastic potential energy, at this time, the first elastic member 3410 generates a force on the pawl 3100, which makes the pawl 3100 have a tendency to switch from the third position to the fourth position. When the driving mechanism 4000 drives the rotating shaft 3300 to rotate, the rotating shaft 3300 drives the pawl 3100 to rotate so that the pawl 3100 unlocks the cover 2000, and after the cover 2000 opens the dispensing opening 1200 and separates from the pawl 3100, the first elastic member 3410 releases the elastic potential energy, thereby driving the pawl 3100 to switch from the third position to the fourth position. Optionally, the first elastic member 3410 is sleeved on the rotating shaft 3300, so that the arrangement of the first elastic member 3410 is more convenient. It can be understood that the first elastic member 3410 can be a spring, a pull rope, etc., and the second elastic member 3420 and the third elastic member are also the same, which will not be repeated here.

[0068] Further, in combination with Figure 5 and Figure 9 As shown, in some embodiments, the cover 2000 drives the pawl 3100 to switch from the fourth position to the third position when the cover 2000 switches from the state of opening the dispensing opening 1200 to the state of closing the dispensing opening 1200. It can be understood that the cover 2000 can be electrically switched from the state of opening the dispensing opening 1200 to the state of closing the dispensing opening 1200, or it can be manually switched, for example, during the operation of the washing appliance, the cover 2000 is switched from the state of closing the dispensing opening 1200 to the state of opening the dispensing opening 1200, and after the operation of the washing appliance is completed, the user can re-place the detergent and manually switch the cover 2000 to the state of closing the dispensing opening 1200, at this time, the cover 2000 cooperates with the pawl 3100. In this embodiment, when the cover 2000 switches to the state of closing the dispensing opening 1200, the cover 2000 drives the pawl 3100 to switch from the fourth position to the third position, so that the pawl 3100 is clamped into the gap 3120, so that the rotating shaft 3300 can drive the pawl 3100 to rotate during the next detergent dispensing. Optionally, the cover 2000 is provided with a protrusion 2200, and the cover 2000 is adapted to push the pawl 3100 through the protrusion 2200 to drive the pawl 3100 to switch from the fourth position to the third position. Through the arrangement of the protrusion 2200, it is easier to push the pawl 3100 by the cover 2000.

[0069] In combination with Figure 4 , Figure 5 , Figure 6 , Figure 9 andFigure 13 As shown, in some embodiments, the pawl 3100 is provided with a locking portion 3130, and the cover 2000 is provided with an abutting portion 2100, the locking portion 3130 is adapted to stop the abutting portion 2100 in the direction in which the cover 2000 opens the dispensing opening 1200, so that the cover 2000 is in the state of closing the dispensing opening 1200, and the locking portion 3130 is adapted to separate from the abutting portion 2100 when the pawl 3100 moves, so that the cover 2000 is switched from the state of closing the dispensing opening 1200 to the state of opening the dispensing opening 1200.

[0070] When the cover 2000 is in the state of closing the dispensing opening 1200, the locking portion 3130 stops the abutting portion 2100, the pawl 3100 locks the cover 2000, and the cover 2000 cannot move in the direction in which the cover 2000 opens the dispensing opening 1200, so that the cover 2000 cannot be switched from the state of closing the dispensing opening 1200 to the state of opening the dispensing opening 1200, i.e., the cover 2000 is maintained in the state of closing the dispensing opening 1200. When it is necessary to dispense detergent, the driving mechanism 4000 drives the pawl 3100 to move, and the pawl 3100 moving causes the locking portion 3130 to separate from the abutting portion 2100, for example, the driving mechanism 4000 controls the rotating shaft 3300 to rotate, the rotating shaft 3300 drives the pawl 3100 to rotate, and the pawl 3100 rotating causes the locking portion 3130 to separate from the abutting portion 2100, so that the locking portion 3130 no longer stops the abutting portion 2100 in the direction in which the cover 2000 opens the dispensing opening 1200, and the cover 2000 can be opened under the action of the elastic member (the third elastic member), so as to be switched from the state of closing the dispensing opening 1200 to the state of opening the dispensing opening 1200. It can be understood that when the pawl 3100 is driven to move by the operating member 3200, the cooperation between the pawl 3100 and the cover 2000 is also the same, and will not be repeated here.

[0071] Further, in some embodiments, when the cover 2000 is switched from the state of opening the dispensing opening 1200 to the state of closing the dispensing opening 1200, the abutting portion 2100 of the cover 2000 touches the locking portion 3130 of the pawl 3100, so that the pawl 3100 moves in the direction of unlocking the cover 2000 and then moves reversely to stop the abutting portion 2100 in the direction in which the cover 2000 opens the dispensing opening 1200.

[0072] Specifically, when the abutting portion 2100 contacts the locking portion 3130 during the process of switching the cover 2000 to the state of closing the drop opening 1200, the abutting portion 2100 generates a force on the locking portion 3130 through the improvement of the structure of the two, which promotes the pawl 3100 to move (e.g., rotate) in the direction of unlocking the cover 2000, thus forming an avoidance for the abutting portion 2100. With the cover 2000 moving into place, the pawl 3100 moves in the opposite direction of the direction of unlocking the cover 2000 to reset, thus stopping the abutting portion 2100 in the direction of opening the drop opening 1200 by the cover 2000, so that the cover 2000 is maintained in the state of closing the drop opening 1200.

[0073] The pawl 3100 moves in the opposite direction of the direction of unlocking the cover 2000 to reset is achieved by the second elastic member 3420, which is combined with Figures 4 to 6 and Figure 8 、 Figure 9 As shown in FIG. 13, in some embodiments, the drop device further comprises a second elastic member 3420, which is adapted to generate a force on the pawl 3100 to generate a resisting force on the pawl 3100 when the pawl 3100 moves to unlock the cover 2000. Specifically, when the rotating shaft 3300 drives the pawl 3100 to move to unlock the cover 2000 or when the operating member 3200 drives the pawl 3100 to move to unlock the cover 2000, the second elastic member 3420 generates elastic deformation to accumulate elastic potential energy and generate a resisting force on the pawl 3100 with the movement of the pawl 3100. After the pawl 3100 unlocks the cover 2000, the second elastic member 3420 can release the elastic potential energy to drive the pawl 3100 to reset in the opposite direction of the direction of unlocking the cover 2000, which facilitates the pawl 3100 to cooperate with the cover 2000 to achieve the locking of the cover 2000 when the cover 2000 re-closes the drop opening 1200.

[0074] For example, when the driving mechanism 4000 drives the rotating shaft 3300 to rotate to drive the pawl 3100 to rotate or the operating member 3200 drives the pawl 3100, the pawl 3100 rotates to unlock the cover 2000, and at the same time, the pawl 3100 elastically deforms the second elastic member 3420. After the cover 2000 opens the drop opening 1200, the first elastic member 3410 releases the elastic potential energy to drive the pawl 3100 to move from the third position to the fourth position, and the second elastic member 3420 releases the elastic potential energy to drive the pawl 3100 to reset in the direction opposite to the direction of rotation of the cover 2000. When the cover 2000 switches to the state of closing the drop opening 1200, the abutting portion 2100 contacts the locking portion 3130, and the abutting portion 2100 generates a force on the locking portion 3130, which drives the pawl 3100 to rotate in the direction of unlocking the cover 2000, thereby forming an avoidance of the abutting portion 2100. At this time, the second elastic member 3420 elastically deforms, and with the movement of the cover 2000 to the position, the second elastic member 3420 releases the elastic potential energy (i.e., restores the deformation), and the second elastic member 3420 generates a force on the pawl 3100 to reset the pawl 3100 in the direction opposite to the direction of rotation of the cover 2000. Thus, the abutting portion 2100 can be stopped in the direction of opening the drop opening 1200 by the cover 2000, so that the cover 2000 is maintained in the state of closing the drop opening 1200. At this time, the cover 2000 drives the pawl 3100 to switch from the fourth position to the third position, and the first elastic member 3410 elastically deforms to generate a force on the pawl 3100.
