Description

Technical Field

[0001] This utility model relates to the field of washing machines, and in particular to a dual-engine washing machine with a pulsator and a roller. Background Technology

[0002] Currently, washing machines are divided into two types: top-loading (pulsator) and front-loading (drum). A top-loading washing machine has a pulsator at the bottom of a fixed drum that drives the water flow to wash clothes. A front-loading washing machine has a rotating drum inside an outer drum to hold the clothes, and the drum's rotation tumbles the clothes. Both structures essentially require a power mechanism to drive the pulsator or drum to rotate, thereby moving the water or clothes for cleaning. However, a drawback is that due to the limitations of the motor, the maximum rotational speed and switching efficiency of the drum or pulsator are limited. Especially in the process of miniaturizing washing machines, smaller motors have relatively weaker power. The maximum rotational speed and switching efficiency of the pulsator and drum further restrict washing efficiency. Therefore, small top-loading washing machines have good washing results but are difficult to dry, while small front-loading washing machines are easy to dry but have poor washing results. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a dual-engine washing machine with a pulsator and a roller.

[0004] The technical solution adopted by this utility model to solve the problem is: a dual-engine washing machine, comprising: The washing machine body includes an outer drum, a drum rotatably mounted inside the outer drum, and a pulsator rotatably mounted at the bottom of the drum. A first power mechanism is connected to the drum and is used to drive the drum to rotate. The second power mechanism is connected to the impeller and is used to drive the impeller to rotate.

[0005] As a further improvement to the above technical solution, the axis of the outer drum is arranged at an angle to the bottom surface of the washing machine body, and the axes of the drum and the impeller are collinear with the axis of the outer drum.

[0006] As a further improvement to the above technical solution, the angle between the axis of the outer drum and the bottom surface of the washing machine body is between 20 and 50 degrees.

[0007] As a further improvement to the above technical solution, a dual-rotor motor is provided at the bottom of the outer cylinder. The dual-rotor motor is provided with a first output shaft and a second output shaft arranged coaxially. The first output shaft and the second output shaft respectively constitute the first power mechanism and the second power mechanism.

[0008] As a further improvement to the above technical solution, the dual-rotor motor includes a central stator, an inner rotor disposed within the stator, and an outer rotor surrounding the outer periphery of the stator. The inner rotor has a first channel passing through both sides in its middle. The second output shaft is directly connected to the inner rotor. The second output shaft has a second channel coaxial with and connected to the first channel in its middle. The first output shaft is synchronously arranged in the first channel and the second channel. The end of the first output shaft has a connecting plate that passes through the inner rotor and the stator end and connects to the end of the outer rotor. The front end of the first output shaft extends to the front end of the second output shaft.

[0009] As a further improvement to the above technical solution, the washing machine body is provided with a shock-absorbing device connected to the outer drum.

[0010] As a further improvement to the above technical solution, the shock absorption device includes a first sleeve disposed vertically inside the washing machine body and a second sleeve disposed at the lower part of the outer drum and perpendicular to the washing machine body. The first sleeve and the second sleeve are sleeved together, and shock absorption springs are respectively connected to the washing machine body and the outer drum inside the first sleeve and the second sleeve.

[0011] The beneficial effects of this invention are as follows: By incorporating both a drum and a pulsator at the bottom of the washing machine, and using a first power mechanism and a second power mechanism to drive the drum and pulsator to rotate respectively, the clothes or water flow can be propelled at a higher speed and with greater reciprocating efficiency, resulting in a more effective cleaning of the clothes. Depending on the needs, the rotation speed and frequency of rotation direction switching between the drum and pulsator can be set to allow for more diverse control over the movement of water and clothes, thus enabling more precise cleaning.

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Reference Figures 1 to 2 A dual-engine washing machine, comprising: The washing machine body 10 has an outer drum 20 inside it, a drum 30 rotatably mounted inside the outer drum 20, and a pulsator 40 rotatably mounted at the bottom of the drum 30. A first power mechanism is connected to the roller 30 and is used to drive the roller 30 to rotate. The second power mechanism is connected to the impeller 40 and is used to drive the impeller 40 to rotate.

[0019] By incorporating a drum 30 and an impeller 40 at the bottom of the washing machine, and using a first power mechanism and a second power mechanism to drive the drum 30 and impeller 40 to rotate respectively, the clothes or water flow can be propelled at a higher speed and with greater reciprocating efficiency, resulting in a more effective cleaning. Depending on the needs, the rotation speed and frequency of rotation switching between the drum 30 and impeller 40 (co-rotating or counter-rotating) can be set, allowing for more diverse control over the movement of water and clothes, thus enabling more precise cleaning. For example, during washing, the impeller 40 and the drum 30 can rotate in opposite directions, which is equivalent to rubbing the clothes from top to bottom, thus greatly improving the washing ratio. During spin-drying, the impeller 40 and the drum 30 spin-dry synchronously in the same direction at high speed, which prevents the clothes from being pulled back during spin-drying. During drying, the impeller 40 and the drum rotate in a staggered manner, which can quickly shake the clothes apart and dry them quickly.

[0020] In this design, the drum 30 can be arranged horizontally or vertically. Considering that the drum 30 washing machine has a better tumbling effect on clothes, while the pulsator 40 washing machine has a higher dehydration efficiency, in order to combine the advantages of both types of washing machines, it is preferable that the axis of the outer drum 20 is inclined to the bottom surface of the washing machine body 10, and the axes of the drum 30 and the pulsator 40 are collinear with the axis of the outer drum 20. Preferably, the angle between the axis of the outer drum 20 and the bottom surface of the washing machine body 10 is between 20 and 50 degrees.

[0021] In this solution, a preferred embodiment includes a dual-rotor motor 50 disposed at the bottom of the outer cylinder 20. The dual-rotor motor 50 is provided with a first output shaft 51 and a second output shaft 52 arranged coaxially. The first output shaft 51 and the second output shaft 52 respectively constitute the first power mechanism and the second power mechanism. By synchronously constituting the first power mechanism and the second power mechanism by the dual-rotor motor 50, the number of overall parts can be reduced, and the circuit layout is simpler.

[0022] Preferably, the dual-rotor motor 50 includes a central stator 53, an inner rotor 54 disposed within the stator 53, and an outer rotor 55 surrounding the outer periphery of the stator 53. The inner rotor 54 has a first channel penetrating both sides in its middle. The second output shaft 52 is directly connected to the inner rotor 54. The second output shaft 52 has a second channel coaxial with and connected to the first channel in its middle. The first output shaft 51 is synchronously arranged in the first channel and the second channel. The end of the first output shaft 51 is provided with a connecting plate that passes through the ends of the inner rotor 54 and the stator 53 and connects to the end of the outer rotor 55. The front end of the first output shaft 51 extends to the front end of the second output shaft 52.

[0023] However, it can also be any existing dual-rotor motor 50, for example, the stator 53 is arranged in the middle of the motor body, and the two sets of rotors are arranged in parallel along the horizontal direction on the outside of the stator 53.

[0024] In other embodiments, the dual-rotor motor 50 may not be used. Instead, two independent motors may be used to form the first power mechanism and the second power structure. For example, the first power structure may be the first motor and the second power mechanism may be the second motor. The first power motor is arranged at the bottom of the outer cylinder 20 and extends into the outer cylinder 20 and the drum 30 for connection with the impeller 40. A first gear is provided on the bottom outer surface of the drum 30. The second power motor is eccentrically arranged at the bottom of the outer cylinder 20, and the output end of the second power motor extends into the outer cylinder 20 and is located on the bottom outer surface of the drum 30. A second gear that meshes with the first gear is provided on the output end of the second power motor, thereby driving the drum 30 to rotate.

[0025] To avoid vibrations during washing, the washing machine body 10 is preferably equipped with a shock-absorbing device 60 connected to the outer drum 20. Preferably, the shock-absorbing device 60 includes a first sleeve vertically arranged inside the washing machine body 10 and a second sleeve arranged at the lower part of the outer drum 20 and perpendicular to the washing machine body 10. The first and second sleeves are sleeved together, and shock-absorbing springs, respectively connected to the washing machine body 10 and the outer drum 20, are disposed within the first and second sleeves. However, the shock-absorbing device 60 can also be other existing shock-absorbing methods, such as using a spring suspension at the top of the outer drum 20 for shock absorption, or using a shock-absorbing pad at the bottom of the outer drum 20 for shock absorption.

[0026] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
