DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application discloses a washing, dyeing and drying machine. Figure 1 , including a cylinder 1 into which the cloth is placed to be turned over, the cylinder 1 is connected to a water inlet pipe 3 for feeding clean water, a water inlet valve 29 is connected between the water inlet pipe 3 and the cylinder 1, the water inlet pipe 3 can be composed of a tap water pipe and a recycled water pipe, and the cylinder 1 is also connected to a drain valve 11 for discharging cleaning water. The cylinder 1 is also connected to a material pump 4, the water inlet of the material pump 4 is connected to a material barrel 2, and dye liquid is placed in the material barrel 2 so that the dye liquid can be pumped into the cylinder 1 during dyeing.

[0033] Reference Figure 2 The cylinder 1 comprises an outer cylinder 31 and an inner cylinder 32 coaxially sealed and rotatably connected to the inner wall of the outer cylinder 31. The surface of the inner cylinder 32 is densely covered with holes for liquid to enter and exit the inner cylinder 32. The outer cylinder 31 is detachably connected to an inner cylinder motor 39 that drives the inner cylinder to rotate through a belt and a pulley. A cylinder rack 26 is placed on the ground around the outer cylinder 31, and a plurality of air springs 27 are detachably connected between the cylinder rack 26 and the outer cylinder 31. An outward-turning door 36 that can close the opening of the outer cylinder 31 is hinged at the opening of the outer surface of the circumference of the outer cylinder 31. The rotation axis direction of the outward-turning door 36 is consistent with the axis direction of the outer cylinder 31. The outward-turning door 36 can be supported by the gas spring and can be hooked by a hook driven by the cylinder to rotate after turning down, so that the liquid in the outer cylinder 31 is not easy to leak out during the rotation of the inner cylinder 32. An inward-turning door 33 is hinged on the circumferential outer wall of the inner cylinder 32, and the surface of the inward-turning door 33 is densely covered with holes. An insertion rod 34 is slidably connected to the circumferential outer wall of the inward-turning door 33 along the axial direction of the inner cylinder 32, and a compression spring 35 is installed between the insertion rod 34 and the inward-turning door 33 to force the insertion rod 34 to be inserted into the inward-turning door 33 and the inner cylinder 32, so that the insertion rod 34 can be moved when the inward-turning door 33 needs to be opened.

[0034] Reference Figure 1 and Figure 3 , a positioning rod is fixedly connected to the periphery of the end surface of the inner cylinder 32, and a proximity switch 38 is detachably connected to the inner wall of the end surface of the outer cylinder 31. The inner cylinder motor 39 and the proximity switch 38 are both electrically connected to the controller 21. When the inner cylinder 32 needs to stop rotating and has reached a lower rotation speed, and the positioning rod is facing the proximity switch 38, the proximity switch 38 sends a signal to the controller 21, and the inner cylinder motor 39 stops rotating at this time, so that the inner flip door 33 is facing the outer flip door 36 at this time. In addition, the outer cylinder 31 is connected to the outer cylinder liquid level meter 23, which can be a magnetic flap type and electrically connected to the controller 21, and the material pump 4 is electrically connected to the controller 21, so that when the liquid level detected by the outer cylinder liquid level meter 23 exceeds the preset liquid level height in the controller 21, the material pump 4 stops running.

[0035] Reference Figure 1 and Figure 3 The outer cylinder 31 is connected to a circulation pump 47, and the water outlet of the circulation pump 47 is connected to a filter 48 which may be a basket type. The water outlet of the filter 48 is connected to a heat exchanger 49 which is located outside the outer cylinder 31 and may be a tube sheet type and can heat the dye solution or clean water. The water outlet of the heat exchanger 49 is connected to the outer cylinder 31. The outer cylinder 31 is also detachably connected to a thermometer 24 which is electrically connected to the controller 21. After the temperature value detected by the thermometer 24 is lower than the temperature value preset by the controller 21, the circulation pump 47 starts to run to send the liquid in the outer cylinder 31 into the heat exchanger 49 until the temperature value detected by the thermometer 24 reaches the standard.

[0036] Reference Figure 1 The barrel 2 includes a row of lower barrels 56 and a row of upper barrels 57. The height of the upper barrels 57 is higher than that of the lower barrels 56. Each upper barrel 57 is located directly above a lower barrel 56. The upper barrels 57 are filled with dye stock solution. The bottom of the upper barrels 57 is connected with a liquid replenishing valve 58 electrically connected to the controller 21, so that the liquid replenishing valve 58 can put the dye stock solution into the lower barrels 56. Only the lower barrels 56 are connected with the inlet and outlet valves 46 electrically connected to the controller 21, and the inlet and outlet valves 46 are connected to the water inlet of the material pump 4. A rear return liquid pipe 59 electrically connected to the controller 21 is connected between the lower cylinder 56 and the water inlet of the material pump 4, and one end of the rear return liquid pipe 59 away from the water inlet of the material pump 4 is connected to the water outlet of the material pump 4, and the pipe body of the rear return liquid pipe 59 is provided with a rear return liquid valve 41 electrically connected to the controller 21; a front return liquid pipe 42 electrically connected to the controller 21 is connected between the cylinder 1 and the water outlet of the material pump 4, and the pipe body of the front return liquid pipe 42 is provided with a front return liquid valve 43 electrically connected to the controller 21; a front sealing valve 44 electrically connected to the controller 21 is connected between the front return liquid pipe 42 and the water outlet of the material pump 4, and a rear sealing valve 45 electrically connected to the controller 21 is connected between the front return liquid pipe 42 connecting the water inlet of the material pump 4 and the rear return liquid pipe 59 connecting the water inlet of the material pump 4.

[0037] When the dye liquid needs to be pumped into the outer cylinder 31, the inlet and outlet valves 46, the rear sealing valve 45 and the front sealing valve 44 are opened, and the rear return valve 41 and the front return valve 43 are closed, so that the dye liquid in the lower cylinder 56 can be pumped into the outer cylinder 31. After the fabric is dyed, the inlet and outlet valves 46, the rear return valve 41 and the front return valve 43 are opened, and the rear sealing valve 45 and the front sealing valve 44 are closed, so that the dye liquid in the outer cylinder 31 is pumped into the lower cylinder 56 for storage. And when the dye liquid concentration in the lower cylinder 56 is low, the liquid replenishment valve 58 can be opened to send the dye liquid of the upper cylinder 57 into the low-concentration dye liquid in the lower cylinder 56 to ensure that the dye liquid concentration in the lower cylinder 56 is not too low.

[0038] Reference Figure 3 and Figure 4 The upper barrel 57 and the lower barrel 56 are both detachably connected with an air blowing pipe 28 and a barrel liquid level meter 25. The air blowing pipe 28 is connected to an external air pump to send air into the dye liquid so that the dye liquid in the upper barrel 57 and the lower barrel 56 can keep flowing. The barrel liquid level meter 25 is electrically connected to the controller 21 to monitor the amount of dye liquid in the upper barrel 57 and the lower barrel 56 in real time.

[0039] Reference Figure 1 and Figure 4 A water spray ring 5 is installed around the top opening of each of the lower tube 56 and the upper tube 57. The water spray ring 5 includes a fixed ring tube 53 detachably connected to the lower tube 56 or the upper tube 57. The axis of the fixed ring tube 53 is consistent with the axis of the lower tube 56 or the upper tube 57. The upper surface of the fixed ring tube 53 is coaxially sealed and rotatably connected to a moving ring tube 54. The fixed ring tube 53 is detachably connected to a rotating tube motor 55. The rotating tube motor 55 can drive the moving ring tube 54 to rotate through gears and a gear ring provided on the moving ring tube 54. A cleaning valve 52 electrically connected to the controller 21 is connected between the fixed ring pipe 53 and the water inlet pipe 3. Several water holes 51 are evenly opened around the axis of the bottom of the moving ring pipe 54. The circumferential inner walls of the lower cylinder 56 and the upper cylinder 57 are inclined, and the diameters of the upper cylinder 57 and the lower cylinder 56 are larger at higher heights, so that the clean water sent out by the water holes 51 can directly fall to the upper part of the circumferential inner wall of the lower cylinder 56 or the upper cylinder 57 to clean and remove the dye on the inner wall of the lower cylinder 56 and the upper cylinder 57. The inlet and outlet valves 46 of all the lower cylinders 56 are connected to the drain valve 22, which can discharge the sewage after the upper cylinder 57 and the lower cylinder 56 are cleaned.

[0040] The implementation principle of a washing, dyeing and dyeing machine in an embodiment of the present application is: when the cloth needs to be dyed, the outer flip door 36 and the inner flip door 33 are opened to put the cloth into the inner drum 32, and then the inner flip door 33 and the outer flip door 36 are closed, and then the material pump 4 is operated to pump the dye liquid in the lower drum 56 into the outer drum 31, and then the inner drum motor 39 is operated to make the inner drum 32 rotate to dye the cloth.

[0041] When the dyeing is finished and the cloth needs to be washed, the water inlet valve 29 is opened to allow clean water to be fed into the outer drum 31, and the inner drum 32 rotates to wash the cloth. When dehydration is required after washing, the drain valve 11 is opened, and the inner drum 32 rotates to a high degree to drain the clean water in the cloth. The steps of washing and dehydrating the cloth can be repeated multiple times to ensure that the cloth is fully washed.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
