detailed description

As shown in FIGS. 1 , 2 , 3 and 4 , a flocculant dispenser for a washing machine includes a material box 4 , a flocculant delivery device, a pre-storage box 7 , and a top extension device 10 .

The material box is connected with a flocculant conveying device, which includes a screw barrel 5 , a conveying screw 2 , a stirring gear 3 and a motor 1 .

The material box 4 is open up and down, and the upper opening of the material box is provided with a sealing cover. The lower end of the material box 4 is connected to the screw barrel 5 in the flocculant conveying device, the screw barrel 5 is a stepped barrel, and the middle part is thicker than the two ends. The wall of the screw barrel 5 is provided with an opening to communicate with the lower opening of the material box 4. The conveying screw 2 is arranged in the screw barrel 5, and one end of the conveying screw 2 is connected with the motor 1. In the present embodiment, the motor 1 adopts a stepping motor. The port at one end of the screw barrel 5 connected to the motor 1 is sealed.

A pre-storage box 7 communicating with the screw barrel 5 is fixed at the port of the screw barrel 5 opposite to the other end of the conveying screw 2, and the lower end of the pre-storage box 7 is provided with an openable and closable blanking port.

In this embodiment, the bottom plate 9 of the pre-storage box 7 is movable, one end of the bottom plate 9 is hinged to the adjacent wall of the pre-storage box, and the other end is a free end. The bottom plate 9 of the pre-storage box 7 is a slant plate, and the hinged end is high, and the free end is low.

A jacking device 10 is installed at the bottom of the screw barrel 5, and the push rod 8 in the jacking device 10 can be stretched. When the push rod 8 stretches out, it contacts the bottom plate 9 of the pre-storage box, and pushes the bottom plate 9 to make it around the hinged end. Rotate until the free end of the base plate 9 contacts with other walls of the pre-storage box 7, so that the bottom end of the pre-storage box 7 is closed. When the push rod 8 was retracted, the base plate 9 drooped under the action of gravity, so that the bottom end of the pre-storage box 7 was opened.

The transition between the upper end and the bottom end of the magazine is through an inverted tapered surface. In order to connect the material box 4 to the screw barrel 5 stably, a reinforcing rib 6 is provided on the outside of the inverted tapered surface of the material box, and the lower end of the reinforcing rib 6 is connected to the screw barrel 5 .

A stirring gear 3 is installed in the feed box 4, and a central shaft is arranged on the stirring gear 3, and both ends of the central shaft are erected on the feed box wall through bearings. The stirring gear 3 meshes with the conveying screw 2 .

In order to make the stirring gear 3 better stir the flocculant, at the position where its central axis is connected with the material box, the wall of the material box is recessed inward, so that the space of the material box here is narrow, and the flocculant flows to both sides , so as to ensure that the stirring gear can stir the flocculant more effectively.

In order to make the flocculant fall into the screw barrel more efficiently and ensure the effective meshing of the stirring gear 3 and the conveying screw 2, the length of the opening on the wall of the screw barrel along the axial direction of the screw barrel is 5-7 times the pitch of the conveying screw. In this way, the flocculant falls into the screw barrel, which can ensure that the 5-7 screw pitches of the conveying screw are filled with flocculant, so that the conveying screw 2 can convey the flocculant as soon as possible and improve the working efficiency.

The size of the opening on the wall of the screw barrel in the axial direction of the screw barrel is 1/3-1/2 of the length of the screw barrel. In this way, it can ensure that the flocculant has enough openings to fall into the screw barrel and improve working efficiency.

In this embodiment, the length of the opening on the wall of the screw barrel in the axial direction of the screw barrel is 6 times the pitch of the conveying screw. The size of the opening on the wall of the screw barrel in the axial direction of the screw barrel is 1/2 of the length of the screw barrel.

In order to make more flocculant fall into the screw barrel and ensure that the conveying screw effectively transports the flocculant without filling the flocculant somewhere between the conveying screw blades, the diameter of the opening on the wall of the screw barrel is larger than that of the screw barrel. The other parts are larger in diameter.

Since the screw barrel is a stepped barrel, the middle part of the screw barrel is provided with an opening, and the middle part is thicker than the two ends. The size of the opening on the wall of the screw barrel in the radial direction of the screw barrel is equal to the diameter of the screw barrel where the opening is located. That is, the part of the screw barrel where the opening on the wall of the screw barrel is located is a semi-cylinder with an upward opening, and the upper end of the semi-cylindrical is connected with the lower opening edge of the feed box. In this way, the width of the opening is the largest, and the efficiency of the flocculant falling into the screw barrel is ensured to the greatest extent.

During work, the flocculant is poured into the feed box 4 from the upper opening of the feed box, and sealed with a sealing cover, which can ensure that the flocculant is not easily affected by moisture under conventional placement. The bottom plate 9 of the pre-storage box 7 closes the lower end of the pre-storage box under the action of the push rod 8, as shown in FIG. 2 . The motor 1 drives the conveying screw 2 to rotate, and since the stirring gear 3 meshes with the conveying screw 2, the stirring gear 3 also rotates to stir the flocculant to prevent the flocculant from agglomerating. The flocculant enters the screw barrel 5 from the lower opening of the material box 4, and the conveying screw 2 rotates to output the flocculant from the end of the screw barrel 5 away from the motor and then falls into the pre-storage box 7, which is a flocculant pre-storage device. The number of rotations is controlled by the program control of the stepping motor. Since the structure of the conveying screw 2 can determine the weight of the flocculant injected in each revolution, different injection combinations can meet the actual required dosage. As shown in Figure 3, when the flocculant in the pre-storage box 7 reaches the required dosage, the push rod 8 of the extension device 10 is retracted, so that the bottom plate 9 of the pre-storage box 7 is drooped, and an opening is formed at the bottom of the pre-storage box. The flocculant falls out from the opening at the bottom of the pre-storage box 7, completing a flocculant injection. After all the flocculant falls out, the push rod 8 of the extension device 10 is stretched out, and the base plate 9 is pushed to close the bottom end of the pre-storage box 7 . Using the flocculant dispenser of this solution, the flocculant needed for the next time can be prepared while washing or flocculating the water, and the corresponding amount of flocculant is prepared in advance and injected at one time, which can also save the entire laundry time.

In the flocculant dispenser of the washing machine of the present invention, the motor drives the transmission screw to rotate, and the transmission screw drives the stirring gear to rotate. The stirring gear can stir the flocculant in the material box to facilitate the flow of the flocculant and prevent the flocculant from agglomerating. After the flocculant falls into the screw barrel from the material box, the flocculant is transported out of the screw barrel by the rotation of the conveying screw. Since the pitch of the conveying screw is fixed, the diameter of the screw barrel and the speed of the conveying screw are known, so the flocculant can be realized. The automatic and quantitative delivery not only saves manpower, but also achieves accurate delivery. In addition, a pre-storage box is set at the outlet end of the screw barrel, and the bottom plate at the bottom of the pre-storage box forms an openable and closable discharge port under the action of the push rod of the extension device, and the conveying screw pre-sets the flocculant to be injected Put it in the pre-storage box, which is a flocculant pre-storage device. When the flocculant in the pre-storage box meets the needs of the dosage, the bottom of the pre-storage box is opened to complete the feeding at one time, which shortens the feeding time, thereby reducing the flocculant and flocculant. The time of water vapor contact prevents the phenomenon that the flocculant absorbs moisture due to a long time of putting in.

The implementations in the above examples can be further combined or replaced, and the examples are only descriptions of preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention. Various changes and improvements to the technical solutions of the present invention made by those skilled in the art belong to the protection scope of the present invention.
