[0079] Embodiment 4

[0080] like Figures 1 to 11 As shown, this embodiment introduces a washing machine, on which the washing machine dispensing device described in any one of the above embodiments 1 to 3 is installed. The washing machine described in this embodiment can be a pulsator washing machine or a drum washing machine. For the convenience of description in the present invention, a pulsator washing machine is taken as an example for explanation:

[0081] In this embodiment, the washing machine comprises a housing, a vertically arranged barrel with an open top is arranged in the housing, and a stirring component which can rotate relatively or together is installed in the barrel to stir the water in the barrel and generate a rotating water flow to process the clothes in the barrel. The stirring component comprises: any existing structure or a combination of structures such as a pulsator, an inner barrel, and a stirring column.

[0082] like Figures 1 to 11 As shown, in this embodiment, a control panel seat 400 is provided on the top of the shell, a clothing delivery port corresponding to the opening at the top of the barrel is provided in the middle of the control panel seat 400, and a door cover that can open and close the clothing delivery port is provided on the top of the control panel seat 400. The washing machine delivery box 1 described in any of the above embodiments is installed on the control panel seat 400. Preferably, the delivery box 1 is installed on the inner periphery of the control panel seat 400, and the delivery box 1 is installed on the rear side wall of the clothing delivery port protruding forward, so that the blocking cover 2 on the top wall of the delivery box 1 can be unlocked by the push elastic force pressed downward, and automatically flipped upward and opened by the elastic force component 200, so that the user can conveniently inject additives into the delivery box 1, and then use the washing machine water inlet flow flowing through the delivery box 1 to inject the additives into the washing machine barrel.

[0083] In this embodiment, the specific process of opening the cover 2 on the delivery box 1 is as follows:

[0084] like Fig.11As shown, the baffle cover 2 is in a closed state, and the plug-in shaft 15 of the rocker arm 4 is in the locking groove 10; after the user applies a downward pushing elastic force to the baffle cover 2, the plug-in shaft 15 of the rocker arm 4 is guided by the sliding-out side inclined surface of the stopper 14 and moves toward the sliding-out side of the locking groove 10, and the stopper 14 and / or the locking rib 13 are squeezed by the plug-in shaft 15 to produce elastic deformation and increase the gap distance between the two, and the plug-in shaft 15 passes over the gap between the locking rib 13 and the stopper 14, and the plug-in shaft 15 slides out of the locking groove 10 and moves to the limiting slide groove 9 downstream of the locking groove 10, so that the baffle cover 2 is unlocked. Then, driven by the opening force applied by the elastic component 200 to the baffle cover 2, the baffle cover 2 is automatically flipped upward to open, and the plug-in shaft 15 is limited by the outer ring retaining rib 12 and moves circumferentially in the clockwise direction along the limiting slide groove 9; until as shown in FIG. Figure 6 As shown, the plug-in shaft 15 moves to the limiting slide groove 9 at the opposite end of the locking groove 10; at the same time, when the cover 2 is flipped upward to open, the cover 2 is acted upon by the damping assembly 300 and a damping force is applied thereto to hinder its flipping and opening, so as to avoid the occurrence of situations such as excessive opening speed.

[0085] In this embodiment, the specific process of closing the cover 2 on the delivery box 1 is as follows:

[0086] like Figure 6 As shown in FIG. 1 , the cover 2 is in an open state, and the plug-in shaft of the swing rod 4 is in the limiting slide groove 9 at the end opposite to the locking groove 10; after the user applies a downward closing force to the cover 2, the plug-in shaft 15 of the swing rod 4 is limited by the outer ring retaining rib 12 and moves circumferentially along the limiting slide groove 9 in the clockwise direction; until the locking groove 10 is closed. Fig.11 As shown, the plug-in shaft is limited by the curved portion of the outer ring retaining rib 12 and slides smoothly into the locking groove 10, and the plug-in shaft 15 is blocked by the locking rib 14 so that the cover 2 can no longer move downward. After the user cancels the closing force, the cover 2 is acted upon by the elastic component 200 and has a tendency to flip upward and open, and the plug-in shaft 15 moves to the sliding side. However, since the diameter of the plug-in shaft 15 is greater than the distance between the locking rib 13 and the stop portion 14, the plug-in shaft 15 is limited by the locking rib 13, so that the cover 2 is in a closed position and is locked.

[0087] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as above in the preferred embodiment, it is not used to limit the present invention.
