Description

Technical Field

[0001] This utility model relates to the field of washing machines, and in particular to a fully automatic washing machine. Background Technology

[0002] A washing machine is a household appliance that cleans clothes through mechanical or electrical processes. It mainly consists of a cabinet, a washing and spin-drying tub, a transmission and control system, etc. It relies on a motor to drive the pulsator or drum to rotate, working in conjunction with water flow and detergent to remove dirt. Based on structure, washing machines are classified into pulsator, drum, and twin-tub types. They are characterized by high automation and fast washing efficiency, reducing manual labor and making clothes cleaning more convenient. Widely used in homes and various places, they are an indispensable household appliance in modern life.

[0003] In existing washing machine technology, the magnetic force generated by energizing an electromagnetic coil is often used to attract or release clutch components (such as friction plates or jaws) to control the linkage of the transmission system. When a state needs to be switched, the electromagnetic coil is energized / de-energized, driving the clutch to engage or disengage, thereby switching the power transmission path.

[0004] However, the existing clutch structure has obvious defects in practical applications. The electromagnetic clutch structure is affected by the stability of electromagnetic induction. In long-term use, due to component wear or electromagnetic force attenuation, there will be problems such as delayed clutch action and untimely switching of linkage state. This not only affects the working efficiency of the washing machine, but may also cause equipment failure due to abnormal transmission. In view of this, we propose a fully automatic washing machine.

[0036] Reference Figures 2-4 The automatic clutch switching assembly 2 includes a fixed frame 201. The upper end of the fixed frame 201 is fixedly connected to the spin-dry tub 207. The inner surface of the fixed frame 201 contacts a motor 202. A washing shaft 211 is fixedly connected to the output shaft of the motor 202. A spin-dry shaft 210 is rotatably connected to the outer arc surface of the washing shaft 211. A spline 205 is fixedly connected to the outer surface of the washing shaft 211. A toothed clutch 203 is slidably connected to the lower part of the outer arc surface of the spin-dry shaft 210. A pulsator 208 is fixedly connected to the upper end of the washing shaft 211.

[0037] Reference Figures 4-5 The upper surface of the workbench 3 has a through hole to accommodate the safety cover. The four corners of the fixing bracket 201 have through threaded holes to connect to the spin-dry tub 207. The lower part of the outer arc surface of the spin-dry shaft 210 has a toothed groove to engage with the teeth on the inner arc surface of the toothed insert 203. The outer arc surface of the spline 205 has multiple sets of toothed protrusions to engage with the bottom of the toothed insert 203 when it is in a low position. The lower surface of the toothed insert 203 has a toothed groove. A spring is fixedly connected to the upper surface of the toothed insert 203. When the shift fork 212 moves away from the toothed insert 203, the spring force can push the toothed insert 203 downward and engage with the spline 205. The center of the inner arc surface of the toothed insert 203 has a toothed groove. The upper surface of the impeller 208 has multiple sets of arc-shaped protrusions to wash the clothes inside the spin-dry tub 207 during rotation.

[0038] Reference Figures 6-7 The automatic clutch switching assembly 2 includes a clutch motor 204. The upper end of the clutch motor 204 is provided with a cylindrical protrusion. A cam 209 is fixedly connected to the output shaft of the clutch motor 204. The upper surface of the cam 209 contacts a shift fork 212. The end of the shift fork 212 away from the cam 209 contacts a jaw clutch 203. The outer surface of the shift fork 212 is rotatably connected to the lower end of the bearing seat 206, and the lower surface of the bearing seat 206 meshes with the jaw clutch 203. The upper end of the dehydration shaft 210 is fixedly connected to the dehydration bucket 207 by bolts.

[0039] The upper surface of the cam 209 is inclined, so when it is rotated by the clutch motor 204, it can synchronously push one end of the shift fork 212 to rise or fall. The lower surface of the end of the shift fork 212 near the cam 209 is provided with an arc-shaped protrusion, thereby reducing the possibility of rigid collision between it and the cam 209. The end of the shift fork 212 away from the cam 209 is set in a Y-shape, so it can push the jaw clutch 203 to rise during its rotation. The lower surface of the bearing seat 206 is provided with a toothed groove, so that the jaw clutch 203 can engage with it in the high position. The outer surface of the dehydration bucket 207 and the outer shell 1. A rotatable connection is made, and a drain rod 213 is sleeved on the upper surface of the cam 209. The end of the drain rod 213 near the clutch motor 204 is provided with an arc-shaped groove to accommodate the upper protrusion of the clutch motor 204. The end of the drain rod 213 away from the clutch motor 204 is piston-connected to a drain valve body 214. The drain rod 213 away from the clutch motor 204 is provided with a piston. Therefore, when the drain rod 213 is driven away from the drain valve body 214, the inside of the pipe is in a conductive state, thereby completing the drainage operation. The upper end of the motor 202 is fixedly connected to the dehydration tank 207.

[0040] Working principle: When the device needs to wash the clothes inside, the motor 202 can be started directly, causing it to drive the washing shaft 211 to rotate through its output shaft. During the rotation of the washing shaft 211, the upper impeller 208 will also rotate synchronously, washing the clothes inside. Simultaneously, when the washing is complete and the clothes need to be spun dry, the clutch motor 204 starts and drives the outer cam 209 to rotate. As the cam 209 rotates, its upper surface slope will push the fork 212 closer to one end, causing the other end of the fork 212 to descend. The spring on the upper part of the jaw clutch 203 will be compressed, pushing the jaw clutch 203 downwards. When the jaw clutch 203 moves downwards, the toothed groove on its lower surface will engage the spline 205. Because the spline 205... 05 is fixedly connected to the washing shaft 211, so that the toothed insert 203 is driven to rotate synchronously. The tooth groove on the inner arc surface of the toothed insert 203 will mesh with the teeth on the lower part of the outer arc surface of the spin-drying shaft 210, thereby driving the spin-drying shaft 210 to rotate synchronously. During the rotation of the spin-drying shaft 210, the upper bearing seat 206 and the spin-drying tub 207 fixedly connected to the bearing seat 206 will be driven to rotate synchronously, so that the impeller 208 and the spin-drying tub 207 will rotate synchronously and spin-dry the clothes stored inside. In addition, during the rotation of the clutch motor 204, the upper protrusion will drive the drain pull rod 213 to move towards the clutch motor 204. At this time, the piston at the end of the drain pull rod 213 away from the clutch motor 204 will release the restriction on the drain valve body 214, so that the water inside the spin-drying tub 207 can be discharged through the drain valve body 214.
