washing machine

Abstract

The invention provides a washing machine which washes throughout an outer groove. Thewashing machine (1) is provided with a machine cabinet (2), the outer groove (9) which is supported in the machine cabinet (2) and stores water inside, an inner groove (8) which is supported in the outer groove (9) in a free rotation manner, and a drive device (10) which drives the inner groove (8) to rotate. An upper surface of the inner groove (8) is formed with a water storage portion (30) used to store water. A water supply unit supplying water for the water storage portion (30) is provided. Through driving the drive device (10) and speeding up rotation speed of the inner groove (8), the water supply unit is used to supply water for the water storage portion (30), and stored water sprays towards an inner wall of theouter groove (9).

Description

technical field [0001] The present invention relates to washing machines. Background technique [0002] For washing machines, there are washing machines that can set a course for tank cleaning that is different from washing operation because dirt adheres to the inner tank (washing and dehydrating tank) and the outer tank. However, in the process for cleaning the tank, chemicals for cleaning are required, and the user needs to select the operation of the tank cleaning process, etc., and the cleaning work is cumbersome. [0003] Therefore, tank cleaning of the washing machine is performed by another method, and there is a washing machine in which a concave portion is provided on the upper surface of the inner tank and a water supply unit for supplying water to the concave portion is provided. In this washing machine, the inner tank and the outer tank can be cleaned by supplying water to the recess to overflow the inner tank, or by supplying water while rotating the tank to sc...

AI Technical Summary

Problems solved by technology

[0007] However, in the technology described in Patent Document 1, in the case of cleaning by splashing water toward the outer tank, only the amount of supplied water is diffusely scattered from the concave portion to the outer tank, making it difficult to spread the water over the entire inner peripheral wall of the outer tank.

If the amount of water applied to the outer tank is small, the scattered water will flow along the same path, and the path of the water flowing on the inner peripheral wall of the outer tank will be easily fixed, which may cause uneven washing in the form of stripes.

[0008] In addition, in the technology described in Patent Document 2, since the supplied water flows in a dispersed manner toward the inner peripheral wall of the inner tank and the inner peripheral wall of the outer tank, the amount of water flowing down each tank is reduced. flow in the same path, so there is concern about streaky uneven washing

In addition, the concave portion on the upper surface of the inner tank is provided with an outflow hole, and the water flows to the inner peripheral wall of the inner tank, so that the amount of water flowing to the inner peripheral wall of the outer tank is less, and the above-mentioned uneven washing is likely to occur.
