Referring to fig. 1-9, a dispensing device 10 according to an embodiment of the present invention is used in a washing appliance 100, wherein the washing appliance 100 is, for example, a dishwasher. The dosing device 10 comprises a housing 11 and a drive mechanism 12. A feed cavity 111 and a discharge cavity 112 are formed in the housing 11. The inlet chamber 111 is communicated with the outlet chamber 112. The dosing device 10 comprises a discharge opening 113 communicating with the discharge chamber 112. The driving mechanism 12 includes a motor 121 and a pusher 122. The motor 121 is connected to the pusher 122. The pushing portion 122 is disposed in the discharging cavity 112. The motor 121 is used for driving the pushing part 122 to move back and forth in the discharging cavity 112.

In the above dispensing device 10, the motor 121 can control the distance of the material pushing portion 122 moving back and forth, so that the distance of the material pushing portion 122 moving back and forth each time can be precisely controlled, and then the precision of the amount of detergent dispensed from the discharge port 113 each time by the dispensing device 10 can be ensured, thereby preventing the detergent from being discharged incompletely or wastefully due to too much detergent, and ensuring the stability of the cleaning effect of the washing appliance 100 with the dispensing device 10.

In the present embodiment, the dispensing device 10 is used for dispensing a detergent. In order to ensure that the supply of detergent in the dosing device 10 is sufficient, the volume of the inlet chamber 111 may be made larger than the volume of the outlet chamber 112. So that the detergent in the inlet chamber 111 can be supplied to the outlet chamber 112 for one or more doses.

In some embodiments, the dosing device 10 comprises a control device 13. The control device 13 is electrically connected to the motor 121. The control device 13 is used to control the operation of the motor 121.

Specifically, in the present embodiment, the control device 13 is configured to control the rotation of the motor 121 to control the distance of the pushing unit 122 moving back and forth relative to the discharging chamber 112. The pushing unit 122 can push out the liquid (e.g., detergent) in the discharging chamber 112 and discharge the liquid from the discharging port 113 while moving back and forth with respect to the discharging chamber 112. In this way, the control device 13 can precisely control the distance of the pushing part 122 moving back and forth in the discharging cavity 112 each time, and thus the precision of the detergent amount thrown out from the discharging hole 113 by the throwing device 10 each time can be ensured.

In certain embodiments, the drive mechanism 12 includes a link 123. The connecting member 123 connects the motor 121 and the pusher 122. The motor 121 is used for driving the connecting piece 123 to move so that the connecting piece 123 drives the pushing part 122 to move back and forth in the discharging cavity 112. Specifically, in one embodiment, the connecting member 123 is a rotating shaft, and the control device 13 can control the rotating direction of the rotating shaft 123 by controlling the rotating direction of the motor 121 to control the direction of the pushing part 122 moving back and forth in the discharging cavity 112 relative to the motor 121. The control device 13 can also control the speed of the pushing unit 122 moving back and forth in the discharging chamber 112 by controlling the speed of the motor 121. Therefore, the smooth operation of the pushing part 122 can be realized by controlling the rotation speed of the motor 121, and the discharging stability of the discharging hole 113 can be further ensured, so that the detergent entering the washing appliance 100 can be fully and uniformly mixed with the water.

It should be noted that the distance that the pushing part 122 moves back and forth in the discharging cavity 112 may be set according to specific situations. This can be done by the control device 13 in combination with controlling the speed and time of rotation of the motor 121 to determine the distance the material chamber 112 moves back and forth within the material chamber 112.

In some embodiments, the rotating shaft 123 is rotatably disposed through the housing 11 and extends into the discharging cavity 112 to be directly connected to the pushing portion 122, the rotating shaft 123 is, for example, a screw, the pushing portion 122 is in threaded connection with the rotating shaft 123, and a limiting member for preventing the pushing portion 122 from rotating may be disposed in the discharging cavity 112, so that when the rotating shaft 123 rotates, the pushing portion 122 does not rotate but moves back and forth along the axial direction of the rotating shaft 123. Of course, a sealing member may be appropriately provided at a position where the rotation shaft 123 penetrates the housing 11 to prevent the leakage of the detergent.

In another embodiment, the connecting member 123 may be an expansion link, the connecting member 123 is telescopically connected to the motor 121, the connecting member 123 movably penetrates through the housing 11 and extends into the discharging cavity 112 to be directly connected to the pushing portion 122, and the motor 121 is configured to drive the connecting member 123 to expand and contract so that the connecting member 132 drives the pushing portion 122 to move back and forth in the discharging cavity 112.

In other embodiments, the connecting member 123 may be connected to the pushing member 122 by another member, and such embodiments will be described in detail with the connecting member 123 as a rotation shaft in the embodiments later in the present application.

In some embodiments, delivery device 10 includes a stand 1105. The bracket 1105 is formed with a first mounting slot 1106. The motor 121 is mounted in the first mounting groove 1106. One end of the rotation shaft 123 is connected to the motor 121. The other end of the rotating shaft 123 is rotatably inserted through the sidewall of the first mounting groove 1106 and connected to the pushing part 122. Thus, the support 1105 can prevent the motor 121 from shaking during operation, and then the stability of the operation of the motor 121 can be improved.

In the present embodiment, the housing 11 is formed with a second mounting groove 1107 for mounting the bracket 1105. The bracket 1105 is mounted to the second mounting groove 1107. The dispensing device 10 is thus more compact.

In some embodiments, the dispensing device 10 includes a moving portion 14 and a rotating shaft 123. The rotating shaft 123 is connected with the motor 121. The moving section 14 connects the rotating shaft 123 and the pushing section 122. The motor 121 is used for driving the rotating shaft 123 to rotate so that the moving portion 14 drives the pushing portion 122 to move back in the discharging cavity 112.

Specifically, in the present embodiment, the control device 13 is configured to control the speed and time of the rotation of the motor 121 to control the speed and time of the rotation of the rotating shaft 123 to control the distance of the moving part 14 moving back and forth relative to the motor 121 to control the distance of the pushing part 122 moving back and forth in the discharging cavity 112. In this embodiment, the rotating shaft 123 is connected to the pushing section 122 through the moving section 14.

In some embodiments, the moving portion 14 includes a moving end 141 and a push rod 142. The rotating shaft 123 rotatably penetrates the moving end 141. The motor 121 and the moving end 141 are located outside the housing 11. The push rod 142 penetrates through the housing 11 and connects the moving end 141 and the pushing part 122. Thus, the pushing portion 122 can be driven to move in the discharging cavity 112 by the movement of the moving end 141.

Specifically, in the present embodiment, one end of the rotation shaft 123 is connected to the motor 121. The other end of the rotating shaft 123 rotatably penetrates the moving end 141. When the rotating shaft 123 rotates, the moving end 141 can be driven to move along the rotating shaft 123. One end of the push rod 142 is fixedly connected to the moving end 141. The other end of the push rod 142 is fixedly connected to the pushing member 122 (the pushing member 122 shown in fig. 8 is a pusher plate). When the control device 13 controls the motor 121 to operate, the operating motor 121 drives the rotating shaft 123 to rotate so as to drive the moving end 141 and the push rod 142 to move back and forth relative to the rotating shaft 123.

In some embodiments, the delivery device 10 includes a fixed end 15 located outside the housing 11. The rotation shaft 123 rotatably connects the motor 121 and the fixed end 15. The fixed end 15 is located between the moving end 141 and the pushing section 122. The push rod 142 is movably inserted through the fixing end 15.

Specifically, in the present embodiment, the other end of the rotating shaft 123 rotatably penetrates the moving end 141 and is rotatably connected to the fixed end 15. The other end of the push rod 142 is inserted through the fixed end 15 and fixedly connected to the pushing member 122. When the motor 121 drives the rotating shaft 123 to rotate, the rotating shaft 123 drives the moving end 141 to move along the rotating shaft 123 and drives the pushing rod 142 and the pushing part 122 to move together.

In some embodiments, the number of push rods 142 is two. The two push rods 142 are parallel to each other. The rotating shaft 123 is located between the two push rods 142. Thus, the arrangement of the two parallel push rods 142 can improve the smoothness of the back-and-forth movement of the push rods 142 and the pushing part 122.

In some embodiments, the dosing device 10 comprises a feed valve 16 and a stop device 17. The dosing device 10 comprises a partition 1102 separating the inlet chamber 111 and the outlet chamber 112. The partition 1102 is provided with a feeding port 1131. The feeding port 1131 and the discharging port 113 are located on the same side of the pushing member 122. The feed valve 16 is rotatably installed on the partition 1102 and opens or closes the feed port 1131. The limiting means 17 is mounted to the housing 11. The stop 17 is configured to limit rotation of the inlet valve 16 relative to the delivery port 1131 between a first position and a second position B. With feed valve 16 in the first position, feed valve 16 opens feed port 1131. When feed valve 16 is in second position B, feed valve 16 closes feed port 1131. In this way, the limiting device 17 can limit the rotation of the inlet valve 16 between the first position and the second position B relative to the material delivery opening 1131, so as to prevent the inlet valve 16 from being opened too much when the material delivery opening 1131 is opened, which may result in the failure of the inlet valve 16, and prevent the liquid in the material outlet chamber 112 from returning to the inlet chamber 111.

In this embodiment, when the inlet valve 16 is rotated from the second position B to the first position, the inlet valve 16 opens downward to open the material delivery opening 1131, so that the liquid enters the material outlet 112 from the material delivery opening 1131 to prepare for the next dispensing. The control device 13 can control the motor 121 to operate, and drive the rotating shaft 123 to rotate through the operating motor 121 to drive the moving end 141 and the pushing rod 142 to move relative to the rotating shaft 123 towards the discharge port 113 so as to push the liquid to flow out of the discharge port 113 under the action of the liquid pressure. The inlet valve 16 is also able to rotate from the first position to the second position B under the effect of the liquid pressure in the outlet chamber 112 and finally to be held in the second position B, the inlet valve 16 being rotated upwards to close the delivery opening 1131. The feed valve 16 may be a one-way valve.

In some embodiments, the surface of the partition 1102 located at one side of the feeding cavity 111 is recessed with a guiding groove 1103 connected to the feeding port 1131. In this way, the position of the diversion trench 1103 is lower, so that under the guiding action of the diversion trench 1103, the liquid in the feeding cavity 111 can more easily enter the discharging cavity 112 through the feeding port 1131, and the liquid is not easily remained in the feeding cavity 111.

In some embodiments, housing 11 includes body 110 and cover 1101. A discharge chamber 112 is formed in the body 110. The cover 1101 is opened with a feeding port 1104. The cover 1101 covers the body 110 and forms a feeding cavity 111 with the body 110. The feed inlet 1104 communicates with the feed cavity 111. In this way, the formation of the inlet chamber 111 and the outlet chamber 112 is facilitated.

In the present embodiment, the body 110 has a substantially rectangular shape. The spacer 1102 is integrally formed with the body 110. Thus, the molding is convenient. The partition 1102 forms a side wall common to the inlet chamber 111 and the outlet chamber 112. The cover 1101 is hermetically connected to the spacer 1102.

In some embodiments, the position limiting device 17 includes a first position limiting member (not shown) and a second position limiting member 172. The first limiting member and the second limiting member 172 are respectively disposed at two sides of the material delivery opening 1131. The inlet valve 16 is located between the first and second stop members 172. The second retainer 172 is located in the feed cavity 111. The first limiting member is located in the discharging cavity 112. When feed valve 16 is in the first position, feed valve 16 abuts first stop and when feed valve 16 is in the second position B, feed valve 16 abuts second stop 172. Thus, under the limiting action of the first limiting member and the second limiting member 172, the feeding valve 16 can only rotate between the first limiting member and the second limiting member 172.

In some embodiments, the dispensing device 10 comprises a control device 13 and a reminder device 131. The prompting device 131 is electrically connected to the control device 13. The control device 13 is used for controlling the prompting device 131 to prompt when the motor 121 drives the pushing part 122 to move towards the discharge port 113 and the feeding valve 16 is not in the second position B. In this way, when the pushing unit 122 moves toward the discharge port 113 to push the liquid in the discharge chamber 112 to flow toward the discharge port 113, if the liquid pressure in the discharge chamber 112 cannot push the feed valve 16 to the second position B, the control device 13 can control the prompting device 131 to prompt according to the state information that the feed valve 16 is not located at the second position B, so as to prompt the user to indicate that the liquid in the discharge chamber 112 is insufficient. Therefore, the user can stop the discharging of the dispensing device 10 according to the prompt result of the prompt device 131, or add liquid into the feeding cavity 111 in time for replenishment.

In some embodiments, the dispensing device 10 includes a microswitch device 132. The microswitch device 132 can be switched between an open state and a closed state. The micro switch device 132 is connected to the second position-limiting member 172. The microswitch device 132 is electrically connected with the control device 13. When the motor 121 drives the pushing unit 122 to move toward the discharging port 113 and the feeding valve 16 is located at the second position B, the feeding valve 16 abuts against the second limiting member 172 and triggers the micro switch device 132 to an open state or a closed state, and the control device 13 can control whether the prompting device 131 prompts according to the on-off state of the micro switch device 132.

In the present embodiment, when the motor 121 drives the pushing unit 122 to move toward the discharging port 113 and the feeding valve 16 is at the second position B, the feeding valve 16 abuts against the second limiting member 172 and triggers the micro switch device 132 to an open state, and at this time, the control device 13 can control the prompting device 131 to keep closed according to the state of the micro switch device 132. When the motor 121 drives the pushing unit 122 to move toward the discharging port 113, the feeding valve 16 is not always in the second position B, and the feeding valve 16 does not abut against the second limiting member 172, the micro switch device 132 can control the prompting device 131 to be turned on according to the state of the micro switch device 132 for prompting.

In some embodiments, the dispensing device 10 includes a discharge valve 114 mounted at the discharge port 113. The discharge valve 114 is used to open or close the discharge port 113. When the inlet valve 16 is in the first position, the outlet valve 114 closes the outlet 113, and when the inlet valve 16 is in the second position B, the outlet valve 114 opens the outlet 113. Thus, the discharge of the discharge port 113 can be controlled by the discharge valve 16.

In this embodiment, the dispensing device 10 includes a cylindrical dispensing tube 18 connected to the housing 11. The casting tube 18 is integrally formed with the body 110, thereby facilitating molding. The feed pipe 18 has a discharge port 113. The outlet valve 114 is a one-way valve. The discharge valve 114 is rotatably installed at the discharge port 113. When the control device 13 controls the motor 121 to operate, and the rotating shaft 123 is driven by the operating motor 121 to rotate so as to drive the moving end 141 and the pushing rod 142 to move relative to the rotating shaft 123 in a direction away from the discharging port 113, due to the rising detergent liquid level in the feeding pipe 18, the discharging valve 114 is automatically closed under the action of the negative pressure to promote the detergent to enter the discharging chamber 112 from the feeding chamber 111. When the dispensing device 10 dispenses detergent, the operating motor 121 drives the rotating shaft 123 to rotate to drive the moving end 141 and the pushing rod 142 to move relative to the rotating shaft 123 towards the discharge port 113, at this time, the inlet valve 16 is closed, and the discharge valve 114 is rotated to open. At this time, due to the pressure of the detergent, the discharge valve 114 is opened, and the detergent is normally dispensed.

It can be understood that the upper and lower positions for limiting the rotation of the discharge valve 114 can be set at the position of the discharge port 113 to ensure that the discharge valve 114 is not opened too much and cannot be closed, and the failure occurs.

Referring to fig. 10, the washing appliance 100 according to the embodiment of the present invention includes the dispensing device 10 according to any one of the above embodiments.

In the above-mentioned washing electric appliance 100, the motor 121 can control the distance of the material pushing portion 122 moving back and forth, so that the distance of the material pushing portion 122 moving back and forth each time can be precisely controlled, and then the precision of the detergent amount thrown out by the discharge port 113 each time by the throwing device 10 can be ensured, so that the condition that the detergent is not completely washed due to a small throwing amount or the detergent is wasted due to an excessive throwing amount is not easy to occur, and the stability of the washing effect of the washing electric appliance 100 with the throwing device 10 can also be ensured.
