Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electrical appliances, and in particular to a washing and drying machine. Background Technology
[0002] With the rapid development of smart home technology, washer-dryer combos, which combine washing, dehydration, and drying functions, are gradually becoming core home appliances in modern households. These integrated devices can sequentially complete the entire process of cleaning clothes through program control. Their core working principle is to use the forward and reverse rotation of the drum to achieve tumbling and washing, high-speed centrifugal dehydration, and hot air circulation drying. However, in actual use, it has been found that because the equipment needs to continuously drive the drum to rotate at different speeds during different working stages, the entire machine experiences significant vibration. This severe vibration can cause a series of derivative problems: First, the vibration is transmitted to the ground through the base, potentially causing the equipment to shift or even tip over, especially when installed on wooden floors or balconies. Second, the vibration energy is transmitted through the building structure as structural noise, easily creating noise pollution in apartment buildings. Currently, the industry commonly uses passive vibration reduction solutions, mainly adding rubber cushioning pads and other vibration-damping components to support the base. However, rubber cushioning pads are prone to plastic deformation after long-term compression, reducing their vibration-damping effect, and existing rubber cushioning pads cannot recover and utilize vibration energy.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0041] Unless otherwise stated or defined, the term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.
[0042] For ease of description, unless otherwise stated, the terms "up" and "down" in the following text refer to the same direction as "top" and "bottom". Figure 1 Its vertical direction is consistent.
[0043] like Figures 1 to 5As shown, a washer-dryer combo includes a housing 10, a base 11, a support assembly 12, a first power generation assembly 13, a second power generation assembly 14, and a drum assembly 15. The housing 10 has a cavity, and the base 11, support assembly 12, first power generation assembly 13, second power generation assembly 14, and drum assembly 15 are all installed inside the cavity. A cover is mounted on the upper surface of the housing 10, and the clothes can be placed and removed from the drum assembly 15 by rotating the cover. The base 11 is located at the bottom of the cavity.
[0044] The support assembly 12 includes a first rail seat 121 disposed on the upper surface of the base 11, a second rail seat 122 disposed above the first rail seat 121, a first roller 123 rotatably mounted on the second rail seat 122 and rollingly mounted on the first rail seat 121 along a first arc trajectory, a support seat 125 disposed above the second rail seat 122, and a second roller 124 rotatably mounted on the support seat 125 and rollingly mounted on the second rail seat 122 along a second arc trajectory. The support seat 125, the second roller 124, the second rail seat 122, the first roller 123, and the first rail seat 121 are arranged sequentially from top to bottom. The roller assembly 15 is mounted on the support seat 125. The plane containing the first arc trajectory is vertically oriented, and the plane containing the second arc trajectory is vertically oriented. The plane containing the first arc trajectory and the plane containing the second arc trajectory are perpendicular to each other, that is, the axis of the first roller 123 and the axis of the second roller 124 are both horizontally oriented and perpendicular to each other. When the roller assembly 15 is not working, under the action of gravity, the first roller 123 is located at the lowest point of the first arc trajectory, and the second roller 124 is located at the lowest point of the second arc trajectory.
[0045] Both the first power generation assembly 13 and the second power generation assembly 14 include a power generation electromagnetic damper 131, a driving wheel 132 and a driven wheel 133 that are driven and connected to the output end of the power generation electromagnetic damper 131, and a conveyor belt 134 fitted onto the driving wheel 132 and the driven wheel 133. The power generation electromagnetic damper 131 contains a rotor, a stator, and windings. The working principle of the power generation electromagnetic damper 131 mainly relies on the phenomenon of electromagnetic induction. When a conductor moves in a magnetic field, a current is induced. The magnetic field generated by this current opposes the movement of the conductor; this phenomenon is called electromagnetic damping. Specifically, when a closed conductor moves relative to a magnetic pole, a current is induced. This current generates a magnetic field reaction force in the conductor, thereby opposing the movement of the conductor and achieving a vibration reduction effect. In this application, when the rotor of the power generation electromagnetic damper 131 rotates relative to the stator and windings, a current is induced, which opposes the rotor's movement. This not only achieves a vibration reduction effect but also generates electrical energy through the induced current, thus having a certain energy recovery function.
[0046] The electromagnetic damper 131 of the first power generation component 13 is mounted on the second rail base 122. The driven wheel 133 of the first power generation component 13 is connected to the first roller 123 and rotates synchronously. The electromagnetic damper 131 of the second power generation component 14 is mounted on the support base 125. The driven wheel 133 of the second power generation component 14 is connected to the second roller 124 and rotates synchronously.
[0047] When the roller assembly 15 vibrates during operation, the support base 125 vibrates, causing the first roller 123 to roll along a first arc trajectory on the first rail base 121, and the second roller 124 to roll along a second arc trajectory on the second rail base 122. The rolling of the first roller 123 and the second roller 124 buffers the vibration of the roller assembly 15 in the front-back, left-right, up-down directions. Simultaneously, the rotation of the first roller 123 and the second roller 124 drives the rotor of the generator-type electromagnetic damper 131 to rotate. This allows the generator-type electromagnetic damper 131 to not only generate damping for vibration reduction but also generate current for energy recovery. By electrically connecting the generator-type electromagnetic damper 131 to the driver 151 of the roller assembly 15, the vibration energy is recovered and utilized.
[0048] In one embodiment, the second rail base 122 is provided with a first arcuate guide groove 126, and the first roller 123 is rolled and mounted on the first arcuate guide groove 126. The height of the first arcuate guide groove 126 first decreases and then increases along its extension direction. The support base 125 is provided with a second arcuate guide groove 127, and the second roller 124 is rolled and mounted on the second arcuate guide groove 127. The height of the second arcuate guide groove 127 first decreases and then increases along its extension direction. The first arcuate guide groove 126 provides rolling guidance for the first roller 123, and the second arcuate guide groove 127 provides rolling guidance for the second roller 124. Specifically, the height of the middle part of the first arc guide groove 126 is lower than the height of the two ends of the first arc guide groove 126, and the height of the middle part of the second arc guide groove 127 is lower than the height of the two ends of the second arc guide groove 127. This allows the first roller 123 and the second roller 124 to generate horizontal displacement and vertical displacement when the washing and drying machine vibrates during operation. The vertical displacement of the first roller 123 and the second roller 124 can eliminate part of the vibration energy by gravity, and some of the vibration energy is converted into electrical energy in the winding by the mechanical energy of the rotor of the generator electromagnetic damper 131.
[0049] Optionally, two first limiting pads 128 are spaced apart on the first rail seat 121, and two second limiting pads 129 are spaced apart on the second rail seat 122. The two first limiting pads 128 are spaced apart at both ends of the extension path of the first arc guide groove 126 to prevent the first roller 123 from disengaging from the first arc guide groove 126. The two second limiting pads 129 are spaced apart at both ends of the extension path of the second arc guide groove 127 to prevent the second roller 124 from disengaging from the second arc guide groove 127.
[0050] Furthermore, a first ball bearing is rotatably mounted on the side wall of the first arc guide groove 126, with the spherical surface of the first ball bearing abutting against the end face of the first roller 123. A second ball bearing is rotatably mounted on the side wall of the second arc guide groove 127, with the spherical surface of the second ball bearing abutting against the end face of the second roller 124. This not only prevents the first roller 123 and the second roller 124 from swaying along the axial direction, but also reduces the rolling friction of the first roller 123 and the second roller 124.
[0051] In one embodiment, there are two first rollers 123 and two corresponding first arcuate guide grooves 126, with the two first arcuate guide grooves 126 spaced apart along the axial direction of the first rollers 123. Similarly, there are two second rollers 124 and two corresponding second arcuate guide grooves 127, with the two second arcuate guide grooves 127 spaced apart along the axial direction of the second rollers 124. The drive wheel 132 of the first power generation component 13 is mounted on the end face of one of the first rollers 123, and the drive wheel 132 of the second power generation component 14 is mounted on the end face of one of the second rollers 124. The two first rollers 123 and two second rollers 124 enhance the support stability.
[0052] It is understandable that two of each of the first power generation component 13 and the second power generation component 14 can be provided, with two first power generation components 13 corresponding to two first rollers 123, and two second power generation components 14 corresponding to two second rollers 124.
[0053] In one embodiment, both the first power generation component 13 and the second power generation component 14 further include a tensioning wheel. The tensioning wheel of the first power generation component 13 is rotatably mounted on the second rail base 122 and abuts against the conveyor belt 134 of the first power generation component 13. The tensioning wheel of the second power generation component 14 is rotatably mounted on the second rail base 122 and abuts against the conveyor belt 134 of the second power generation component 14. The tensioning wheel can tension the conveyor belt 134 and prevent the conveyor belt 134 from slipping.
[0054] Optionally, the diameter of the first roller 123 is larger than the diameter of the driving wheel 132 of the first power generation component 13, and the diameter of the driving wheel 132 of the first power generation component 13 is larger than the diameter of the driven wheel 133 of the first power generation component 13. The diameter of the second roller 124 is larger than the diameter of the driving wheel 132 of the second power generation component 14, and the diameter of the driving wheel 132 of the second power generation component 14 is larger than the diameter of the driven wheel 133 of the second power generation component 14, thereby improving transmission efficiency, increasing the number of rotations of the driven wheel 133, and enabling the power generation electromagnetic damper 131 to generate more current, thus improving the efficiency of vibration energy recovery.
[0055] In one embodiment, the washer-dryer combo also includes a first wheel frame 16, a second wheel frame, a third wheel frame 17, and a fourth wheel frame. The first roller 123 is mounted on the second rail base 122 via the first wheel frame 16, and the second roller 124 is mounted on the support base 125 via the second wheel frame. The power-generating electromagnetic damper 131 and driven wheel 133 of the first power generation component 13 are both mounted on the second rail base 122 via the third wheel frame 17, and the power-generating electromagnetic damper 131 and driven wheel 133 of the second power generation component 14 are both mounted on the support base 125 via the fourth wheel frame. The first wheel frame 16, second wheel frame, third wheel frame 17, and fourth wheel frame each include at least one V-shaped frame. The first wheel frame 16 enables the rotatable mounting of the first roller 123, and the second wheel frame enables the rotatable mounting of the second roller 124. The third wheel frame 17 enables the mounting of the first power generation component 13, and the fourth wheel frame enables the mounting of the second power generation component 14.
[0056] Furthermore, there are multiple support components 12, a one-to-one correspondence between the first power generation component 13 and the second power generation component 14, and multiple support components 12 are arrayed on the base 11. Specifically, in this embodiment, there are four support components 12, four first power generation components 13 and four second power generation components 14, which are installed along the four vertices of the square on the upper surface of the base 11 to improve the support stability of the roller assembly 15.
[0057] In one embodiment, the drum assembly 15 includes a driver 151 mounted on a support base 125, an outer drum 152 mounted on the support base 125, and an inner drum 153 mounted inside the outer drum 152. The output end of the driver 151 is connected to the inner drum 153 for transmission. Specifically, the driver 151 is a motor, and the washer-dryer combo also includes a battery and a hot air blower. The motor, hot air blower, and generator-type electromagnetic damper 131 are all electrically connected to the battery. When the drum assembly 15 of the washer-dryer combo is working, it will generate vibration. The generator-type electromagnetic damper 131 converts the vibration energy into electrical energy and stores it in the battery. The battery powers the motor and hot air blower to realize the washing, dehydration, and drying processes of clothes.
[0058] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
