Embodiment 1

[0023] Such as figure 1 , 2 As shown, an automatic powder dispensing device of the present invention is used to dispense powder materials such as powder flocculant or washing powder. It includes a housing 1 and a screw 2. The screw 2 is rotatably installed at the bottom of the inner cavity of the housing and connected to a driving device. 2 is a variable diameter screw, divided into large diameter section, transition section and small diameter section. The diameter of the large diameter section of the screw is the same, and the diameter of the small diameter section of the screw is the same. There is a transition section between the large diameter section and the small diameter section of the screw. The thread diameter of the section gradually changes from large to small, and it is continuous with the thread of the large diameter section; the large diameter section and transition section of the screw are of single helix structure, and the small diameter section of the screw is of...

Embodiment 2

[0038] The washing machine described in this embodiment is equipped with the automatic powder dispensing device described in the first embodiment, which is used to accurately put powder materials such as powder flocculant or washing powder on the washing machine.

Abstract

The invention provides a powder automatic dispensing device and a washing machine. The powder automatic dispensing device comprises a casing and a screw. The screw is rotatably arranged in the cavity of the casing and is connected with a driving device. The screw is a variable diameter screw, and is divided into a large diameter section, a transition section and a small diameter section. The transition section is arranged between the large diameter section and the small diameter section of the screw. The thread diameter of the transition section gradually becomes from large to small, and is continuous with the thread of the large diameter section. The threads of the large diameter section and the transition section of the screw are in single helix structure. The small diameter section of the screw is in double helix structure. A discharge pipe which is communicated with the cavity of the casing and is horizontally placed is arranged at the bottom of the casing. The small diameter section of the screw runs through the discharge pipe, and the outer diameter of the small diameter section of the screw matches the inner diameter of the discharge pipe. The end part, which is away from the casing, of the discharge pipe is closed, and a discharge port is arranged in the pipe wall at the bottom of the discharge pipe. Through the delivery, compression and constant volume of materials, the dispensing of powder materials is accurate. Through the powder automatic dispensing device on the washing machine, powder is accurately dispensed.

Description

Technical field [0001] The invention relates to a putting device and a washing machine, in particular to an automatic powder putting device and a washing machine, belonging to the field of powder material putting devices and washing machines. Background technique [0002] Today's washing machines tend to be more automated and precise, so when placing powder flocculants or washing powders, they need to be accurately placed as needed. In the patent "Washing Powder Conveying Device" (Patent No.: 201220328346.0), it is mentioned that the screw conveying device is used to deliver the washing powder. The structure is simple and reliable, but the accuracy is poor. [0003] In view of this, the present invention is proposed. Summary of the invention [0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic powder dispensing device and a washing machine, which can realize precise dispensing. [0005] In orde...
