[0025] The embodiment of the present application discloses an improved water-saving industrial washing machine. Under the condition that the volumes of the outer drum 2 and the inner drum 3 remain unchanged, a smaller amount of water is introduced into the outer drum 2, so that the amount of water immersed in the bottom of the outer drum 2 remains unchanged, and less water is used to wash clothes. In addition, the water at the bottom of the outer drum 2 is recycled by using the circulation device 6, thereby solving the problem of large water consumption of industrial washing machines in the prior art and effectively improving the water-saving effect of industrial washing machines.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The cross-sections of the first feed port 21 and the second feed port 31 are both circular, and the outer drum 2 and the inner drum 3 are spaced apart. A water guide pipe 12 and a guide pipe 13 are fixed on the body 1. The water guide pipe 12 passes through the body 1 and is connected to the top center of the outer drum 2. The other end of the water guide pipe 12 is connected to the corresponding water supply equipment. One end of the outlet pipe 13 is connected to the bottom of the outer drum 2, and a drainage pump 14 is fixedly installed on the inner bottom wall of the machine body 1. One end of the outlet pipe 13 is connected to the water inlet of the drainage pump 14, and the water outlet of the drainage pump 14 is connected to a through pipe, which passes through the machine body 1 and is connected to the corresponding drainage port. A small amount of water is introduced into the outer drum 2 through the water guide pipe 12 to soak the clothes in the inner drum 3. Due to the spherical shape of the inner drum 3, a small amount of water can be used in the outer drum 2 to soak the clothes in the inner drum 3, thereby achieving a water-saving effect.

[0028] Reference Figure 3 and Figure 4 The inner drum 3 is formed with a plurality of protrusions 32, which are convenient for rubbing clothes. The protrusions 32 are evenly arranged along the inner wall of the inner drum 3 with the rotation axis of the inner drum 3 as the center line, and the protrusions 32 are formed by the concave outer wall of the inner drum 3. The inner diameter of the water seepage hole of the inner drum 3 is larger than the outer diameter. In addition, two spaced reinforcing plates 15 are fixedly installed in the body 1, and a mounting hole is opened in the center of the reinforcing plate 15. The outer drum 2 is inserted into the mounting hole, which can improve the installation and fixation of the outer drum 2. In order to improve the rotation stability of the inner cylinder 3, two limiting devices 5 are arranged inside the outer cylinder 2.

Furthermore, a filtering device can be installed on the water inlet pipe 63, which can be a device that can filter water in the prior art. After water is introduced into the outer drum 2, in order to improve the washing effect on the clothes, the inner drum 3 is driven to rotate, and the circulating water pump 62 is started, which can suck out the water accumulated at the bottom of the outer drum 2 and spray it out through the pressure of the water inlet nozzle 65 on the circulation pipe 61, so that the clothes are completely soaked. During the rotation of the inner drum 3, the water sprayed by the water inlet nozzle 65 can improve the washing force on the clothes and enhance the washing effect.

The upper edge of the first curved panel 41 is hinged with the outer side wall of the inner cylinder 3. The cylinder door 4 covers the inner cylinder 3, so that the inner cylinder 3 can maintain a complete spherical cylinder. The side where the first curved panel 41 and the second curved panel 42 are spliced ​​is a horizontal plane. The side opposite to the first curved panel 41 and the second curved panel 42 is a circular arc surface that fits the side wall of the second feed port 31. The splicing of the first curved panel 41 and the second curved panel 42 is hinged.
