Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following describes the defect management modes in the embodiments in detail with reference to the drawings in the embodiments of the present invention.
Example 1
In the past, the self-generating device of the washing machine usually utilizes the rotation of the washing machine to cause the vibration of the self-generating device, the vibration of the self-generating device cuts the magnetic induction lines to generate induction current, and the self-generating device needs to be arranged outside the rotating inner barrel of the washing machine and cannot be in contact with the inner barrel. Because the self-generating device does not contact the inner barrel, more rotating energy can only be converted into smaller vibration energy in the vibration process of changing the rotation of the washing machine into the self-generating device, and the efficiency of converting the energy by the self-generating device is lower.
The self-generating device 3 for the washing machine provided by the embodiment converts the mechanical energy of the rotation of the washing machine into the electric energy, but the self-generating device 3 for the washing machine has higher conversion efficiency compared with the traditional self-generating device for the washing machine due to the installation position and the internal structure of the self-generating device 3 for the washing machine.
As shown in fig. 1, the bottom of the inner tub 14 of the washing machine is often provided with a pulsator 1, and the pulsator 1 supplies energy to the pulsator 1 by being connected to a power transmission module 15, so that the pulsator 1 rotates around an axis to achieve an effect of washing laundry. The impeller 1 is often provided with a profiling to facilitate the generation of eddy currents. As shown in fig. 2, the bottom of the pulsator 1 of the present embodiment has a groove 2 depressed from the bottom of the tub toward the top of the tub, and a self-generating device 3 for converting mechanical energy of the rotation of the pulsator 1 into electrical energy is fixed in the groove 2. The self-generating device 3 only needs to be arranged on the impeller 1, and other positions of the impeller 1 can be arranged if the impeller 1 does not have the groove 2, and the groove 2 is preferably arranged. The arrangement enables the self-generating device 3 to rotate together with the impeller 1. The outside of the self-generating device 3 is preferably provided with a housing that prevents water from flowing into the self-generating device 3.
The self-generating device 3 comprises a fixed part fixed in the self-generating device 3, a moving assembly moving relative to the fixed part along with the rotation of the wave wheel 1, a part for generating magnetic induction lines is arranged on one of the fixed part and the moving assembly, a cutting magnetic induction line part is arranged on the other of the fixed part and the moving assembly, and the relative movement of the fixed part and the moving assembly generates the action of cutting the magnetic induction lines to generate electric energy. As shown in fig. 2 to 4, the self-generating device 3 is provided with a permanent magnet 4 for generating magnetic induction lines and a coil winding 6 for cutting the magnetic induction lines, one of the fixed part and the moving component is provided with the permanent magnet 4, the other is provided with the coil winding 6, and the permanent magnet 4 and the coil winding 6 perform relative movement to cut the magnetic induction lines and generate current. That is, the fixed coil winding 6 cuts the permanent magnet 4 which moves relatively to generate magnetic induction lines, or the fixed permanent magnet 4 generates magnetic induction lines which are cut by the coil winding 6 which moves relatively to generate current in both cases.
The relative movement comprises that the centrifugal force of the rotation of the impeller drives the permanent magnet 4 or the coil winding 6 to do quasi-simple harmonic movement along the radial direction of the impeller; the motion assembly comprises a simple harmonic motion assembly 5 which generates simple harmonic motion relative to the permanent magnet 4 or the coil winding 6 along with the rotation of the impeller 1. I.e. a relative harmonic-like movement between the permanent magnet 4 and the coil winding 6.
As shown in fig. 3 and 4, the quasi-simple harmonic motion assembly 5 extends along the radial direction of the pulsator 1, and a vibrator which can move along the radial direction of the pulsator 1 is arranged in the quasi-simple harmonic motion assembly 5. The vibrator in the embodiment is the permanent magnet 4, and when the impeller 1 rotates around the shaft, the permanent magnet 4 can obviously reciprocate along the radial direction of the impeller 1 under the action of the rotating centrifugal force to form the simple harmonic motion. Because the permanent magnet 4 reciprocates along the radial direction of the impeller 1, only the fixed coil winding 6 is arranged outside the quasi-simple harmonic motion assembly 5, so that the magnetic induction line generated by the permanent magnet 4 can be cut by the coil winding 6 to generate induction current. The magnetic induction lines generated by the permanent magnets 4 are as shown in fig. 11, and it is apparent that as the permanent magnets 4 move, the coil windings 6 will cut the magnetic induction lines to generate current. In the embodiment, the radial centrifugal force generated by the rotating impeller 1 is utilized, and the permanent magnet 4 in the quasi-simple harmonic motion assembly 5 is driven to perform radial reciprocating motion through the radial centrifugal force, so that the magnetic induction lines generated by the permanent magnet 4 are cut to generate current. That is, in the present embodiment, the rotation of the pulsator 1 is directly utilized to drive the self-generating device 3 to rotate and the self-generating device 3 is made to perform the motion of cutting the magnetic induction lines to generate the current. Because from power generation facility 3 direct fixation on impeller 1, can directly utilize the pivoted mechanical energy of impeller 1 to convert the electric energy into for the efficiency that the rotatory mechanical energy of impeller 1 of the self power generation facility 3 that this embodiment provided converts the electric energy into is higher.
As shown in fig. 3, 4 and 7, the self-generating device 3 includes a fixed coil winding 6, the coil of the coil winding 6 is wound along the radial direction of the pulsator 1 and forms an internal hollow structure, the hollow structure is provided with a simple harmonic motion-like assembly 5 which radially penetrates through the coil winding 6, and the simple harmonic motion-like assembly 5 is provided with a permanent magnet 4 which is driven by the centrifugal force generated by the rotation of the pulsator 1 and reciprocates along the radial direction of the pulsator 1. The permanent magnet 4 reciprocates along the radial direction in the quasi-simple harmonic motion assembly 5 extending along the radial direction of the impeller 1, so as to drive the magnetic induction lines to move along the radial direction of the impeller 1, and the coil winding 6 sleeved outside the quasi-simple harmonic motion assembly 5 cuts the magnetic induction lines to generate current in the process of the motion of the permanent magnet 4.
As shown in fig. 4, the harmonic-like motion assembly 5 comprises a sealed pipe 7, springs 8 are arranged at two ends inside the pipe 7, and a permanent magnet 4 which reciprocates along the pipe 7 is arranged in the pipe 7. As shown in fig. 5, which is a schematic view of the state where the permanent magnet 4 moves to the leftmost side of the pipe 7, the permanent magnet 4 will contact the spring 8 located at the left side when the leftmost side is located, and the spring 8 decelerates and cushions the permanent magnet 4 moving to the edge, preventing the permanent magnet 4 from hitting the edge of the pipe 7 during the movement. And the permanent magnet 4 presses the spring 8 when moving on the edge due to the presence of the spring 8, and when the permanent magnet 4 starts to move along the left edge to the right, the pressed spring 8 is released, and further the elastic force of the spring 8 urges the permanent magnet 4 to move. As shown in fig. 6, which is a schematic view of a state where the permanent magnet 4 moves to the rightmost side of the duct 7, the permanent magnet 4 moves to the rightmost side of the duct 7 as same as the leftmost side, the permanent magnet 4 is buffered by means of the spring 8, and the spring 8 supplies energy when the permanent magnet 4 moves in the opposite direction. Preferably, the radial movement range of the permanent magnet 4 within the duct 7 exceeds the radial boundaries of the coil windings 6; so that the permanent magnet 4 can perform the motion of cutting the magnetic induction lines to generate current no matter the permanent magnet is moved to any position. It is further preferred that the permanent magnet 4 is a cylindrical permanent magnet, facilitating the movement of the permanent magnet 4 within the pipe 7.
After the impeller 1 starts to rotate, initial kinetic energy is provided for the permanent magnet 4 in the quasi-simple harmonic motion component 5, and the permanent magnet 4 is used as a vibrator to do quasi-simple harmonic motion. Then, no matter the pulsator 1 rotates clockwise or counterclockwise, the permanent magnets 4 do periodic harmonic-like motion, and the relationship between the current generated by the self-generating device 3 along with the rotation of the pulsator 1 and the time is shown in fig. 12.
The washing machine provided by the embodiment is provided with the self-generating device 3 which is arranged on the impeller 1 and can rotate along with the rotation of the impeller 1, and the centrifugal force generated by the rotation is utilized to enable the permanent magnet 4 to do quasi-harmonic motion along the radial direction of the impeller 1, so that the magnetic induction lines generated by the permanent magnet 4 are cut to generate current. That is, the self-generating device 3 provided in this embodiment moves together with the pulsator 1, so that the rotational mechanical energy of the pulsator 1 can be directly converted into electrical energy, and the self-generating device 3 provided in this embodiment can obtain higher energy conversion efficiency than the conventional self-generating device.
Example 2
