Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, and in particular provides a washing machine. Background Art

[0002] Drum washing machines mainly wash clothes by impact washing, which can prevent clothes from being damaged. However, the drum of current drum washing machines is mostly placed horizontally, and clothes need to be put in or taken out from the front opening of the washing machine, so the user needs to bend over to put in or take out clothes.

[0003] However, when putting clothes into the drum washing machine and taking clothes out after washing, since the washing machine is relatively short, the user needs to bend down to put clothes in or take clothes out. When taking clothes out after washing, the clothes are at the innermost part and may be missed, causing users to experience many inconveniences when using the washing machine.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention

[0005] The present invention aims to solve the above technical problem, that is, to solve the problem that the existing drum washing machine is relatively short and it is inconvenient for users to take and put clothes.

[0006] The present invention provides a washing machine, comprising:

[0007] shell.

[0008] The outer cylinder and the inner cylinder rotatably arranged in the outer cylinder are both arranged in the outer shell.

[0009] The first driving device is connected to the inner cylinder and is used for driving the inner cylinder to rotate.

[0010] The second driving device is arranged in the outer shell and is used for driving the outer cylinder and the inner cylinder to deflect so that the openings of the outer cylinder and the inner cylinder are in a state of tilting upward.

[0011] A third driving device is disposed in the outer shell and is used to drive the outer cylinder and the inner cylinder to reciprocate linearly, so that the outer cylinder and the inner cylinder can be at least partially exposed outside the outer shell.

[0012] In the case of adopting the above technical solution, the first driving device is a power device for washing clothes. The second driving device is a power device for deflecting the outer drum and the inner drum. The third driving device is a power device for making the inner drum and the outer drum move horizontally back and forth. By providing power through different driving devices, the inner drum and the outer drum of the washing machine can achieve different movement modes.

[0013] Preferably, the second driving device comprises:

[0016] A connecting rod has one end hinged to the slider and the other end hinged to the outer cylinder.

[0017] The second driver is arranged at one end of the slide bar. When the second driver drives the slide block to move along the slide bar, the connecting rod swings and drives the outer cylinder to deflect.

[0018] When the above technical solution is adopted, the slider can slide left and right along the slide rod. Driven by the second driver, the slider drives the connecting rod to move on the slide rod. Since the connecting rod is hinged to the slider and the wall of the outer cylinder respectively, when the slider drives the connecting rod to move, the connecting rod will drive the outer cylinder to deflect, thereby realizing the deflection of the inner cylinder.

[0019] Preferably, the second driver is an electromagnet, the slider is a magnetic body, and when the electromagnet is energized, the magnetic body moves along the slide bar under the action of the magnetic field, thereby driving the outer cylinder to deflect.

[0020] In the case of adopting the above technical solution, after being attracted by the electromagnetic force of the electromagnet, the magnetic body moves along the slide bar toward the electromagnet so that the front end of the outer cylinder is pulled up, and the axis of the outer cylinder and the inner cylinder forms an inclined angle with the horizontal direction. In addition, the electromagnet and the magnetic body are used to drive the cylinder and the inner cylinder to deflect, and the inclination angle can be changed by controlling the magnitude of the current. It should be noted that the magnitude of the current can at least tightly adsorb the magnetic body and the electromagnet together after the electromagnet is energized, so that the outer cylinder is tilted to form a fixed inclination angle.

[0021] Preferably, the second driving device further comprises:

[0022] The return spring is sleeved on the slide bar and is located on the side of the magnetic body away from the electromagnet. When the electromagnet is powered on, the magnetic body compresses the return spring. When the electromagnet is powered off, the return spring drives the slide bar to move to the initial position.

[0023] When the above technical solution is adopted, when the electromagnet is powered on, the magnetic body approaches the electromagnet, the reset spring is pulled open, and a certain traction force is generated. When the electromagnet is powered off, the magnetic body is acted upon by the traction force, and the reset spring pulls the magnetic body back to its original position, so that the axis of the outer cylinder returns to the horizontal line.

[0030] When the above technical solution is adopted, the extension amount of the inner tube and the outer tube can be controlled by transmission through the cooperation of the lead screw and the nut, and the cooperation of the lead screw and the nut can also enhance the stability of the movement of the inner tube and the outer tube.

[0031] Preferably, the third driving device comprises:

[0032] A mounting frame is arranged in the housing.

[0033] The rack is slidably arranged on the mounting frame.

[0034] A gear is rotatably arranged in the outer cylinder, and the gear is meshed with the rack.

[0035] A support rod has one end fixedly connected to the rack and the other end hinged to the outer cylinder.

[0036] and a third driver connected to the gear and used for driving the gear to rotate.

[0037] Wherein, the second driving device also includes a base, the sliding rod and the second driver are both fixed on the base, the base is slidably arranged in the outer cylinder, and when the third driving device drives the outer cylinder to move, the outer cylinder drives the base to move synchronously.

[0038] When the above technical solution is adopted, the gear drives the rack to realize linear reciprocating movement by forward and reverse rotation, and then the rack drives the support rod to move. The rack is installed on the mounting frame to ensure that the rack can move linearly without slipping.

[0039] Preferably, it further comprises a sealing ring connected between the opening edge of the outer cylinder and the opening edge of the outer shell.

[0040] Preferably, the sealing ring is a rubber ring or a corrugated hose.

[0041] When the above technical solution is adopted, the retractable sealing ring can ensure the cleanliness of the interior of the shell, and can also facilitate the outer tube and the inner tube to extend out of the shell opening.

[0042] Preferably, the first driving device is arranged on the outer cylinder.

[0043] When the above technical solution is adopted, the first driving device is installed on the outer cylinder, so that the first driving device can move synchronously with the outer cylinder, thereby improving the coordination and integrity of the first driving device and the outer cylinder during movement.

[0050] When the above technical solution is adopted, the power of the first driver is output to the inner drum through the transmission connection between the driving pulley, the driven pulley and the transmission belt, so that the inner drum can be driven to rotate quickly during washing.

[0059] The preferred embodiments of the present invention are described below with reference to the accompanying drawings.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] Reference Figure 1-2The present invention provides a washing machine, comprising a shell 1, an outer drum 2 and an inner drum 3 installed inside the shell 1, wherein the outer drum 2 does not rotate, and the inner drum 3 is rotatably connected to the inside of the outer drum 2 through a rotating shaft 605. A first driving device 6 is connected to the inner drum 3 and is used to drive the inner drum 3 to rotate. A second driving device 7 is arranged in the shell 1 and is used to drive the outer drum 2 and the inner drum 3 to deflect, so that the openings of the outer drum 2 and the inner drum 3 are in an upwardly inclined state. A third driving device 5 is arranged in the shell 1 and is used to drive the outer drum 2 and the inner drum 3 to reciprocate linearly, so that the outer drum 2 and the inner drum 3 can at least partially be exposed outside the shell 1. The first driving device 6 is a power device for the washing machine when washing clothes. The second driving device 7 is a power device for realizing the deflection of the outer drum 2 and the inner drum 3, and the third driving device 5 is a power device for driving the outer drum 2 and the inner drum 3 to extend or retract the shell 1.

[0063] Further, the first driving device 6 comprises: a first driver 601, the first driver 601 is mounted on the bottom side wall of the outer cylinder 2, the output end of the first driver 601 is fixedly connected with a driving pulley 602, a transmission belt 603 is mounted on the driving pulley 602, a driven pulley 604 is mounted on the side of the transmission belt 603 away from the driving pulley 602, and the driven pulley 604 is fixedly connected with the rotating shaft 605 of the inner cylinder 3. The rotating shaft 605 passes through the bottom of the outer cylinder 2 and is rotatably connected with the outer cylinder 2, one end of the rotating shaft 605 is fixedly connected with the bottom of the inner cylinder 3, and the other end is connected with the driven pulley 604. When the first driving device 6 is working, the first driving device 6 transmits power to the inner cylinder 3 through the driving pulley 602, the transmission belt 603 and the driven pulley 604, so that the inner cylinder 3 rotates.

[0064] It can be understood that the first driver 601 is a motor and the transmission belt 603 is a belt.

[0065] Reference Figure 3 Further, the second driving device 7 is slidably mounted on the top of the inner side of the housing 1, and specifically includes a base 701, which is slidably connected to the top of the inner side of the housing 1, and a slide bar 703 is arranged on the base 701, and a slider is slidably connected to the slide bar 703. A reset spring 705 is sleeved on one end of the slide bar 703, and one end of the reset spring 705 is fixedly connected to the base 701, and the other end is fixedly connected to the side wall of the slider. A second driver is fixedly arranged on the end of the slide bar 703 away from the reset spring 705, and the second driver is used to drive the slider to move along the slide bar 703. A connecting rod 706 is hinged on the bottom surface of the slider, and one end of the connecting rod 706 away from the slider is hinged to the outer wall of the outer cylinder 2. When the second driver is driven, the slider moves along the slide bar 703 toward the direction of the second driver, and the slider stretches the reset spring 705. Since the position of the outer cylinder 2 inside the housing 1 is relatively fixed, the outer cylinder 2 will not move with the slider, but will deflect upward by a certain angle under the action of the connecting rod 706.

[0066] Furthermore, the return spring 705 is sleeved on the slide bar 703, one end of which is fixed on the base 701 together with the slide bar 703, and the other end is connected to the magnetic body 704 sleeved on the slide bar 703. When the electromagnet 702 is powered on, the magnetic body 704 approaches the electromagnet 702, and the return spring 705 is pulled apart, generating a certain elastic traction force; when the electromagnet 702 is powered off, under the action of the traction force of the magnetic body 704, the return spring 705 of the magnetic body 704 pulls the magnetic body 704 back to its original position, so that the rotating shaft 605 of the outer cylinder 2 and the inner cylinder 3 is restored to the horizontal line.

[0067] Further preferably, the second driver is an electromagnet 702, and the slider is a magnetic body 704. When the electromagnet 702 is powered on, the magnetic body 704 is acted upon by the magnetic field and moves along the slider 703, thereby driving the outer cylinder 2 to deflect.

[0068] Further, the third driving device 5 includes a lead screw 501 installed at the bottom of the housing 1, a nut 502 is threadedly connected to the lead screw 501, a support rod 503 is fixedly connected to the upper part of the nut 502, and the other end of the support rod 503 is hinged to the wall of the outer tube 2. A third driver 504 is arranged at one end of the lead screw 501. When working, the third driver 504 drives the lead screw 501 to rotate, and the lead screw 501 drives the nut 502 to move. In order to prevent the nut 502 from deflecting under the drive of the lead screw 501, the bottom of the nut 502 needs to contact the bottom of the housing 1, and the nut 502 is slidably connected to the bottom of the inner side of the housing 1. Among them, the base 701 in the second driving device 7 slides relative to the inner top of the housing 1. When the support rod 503 drives the outer tube 2 to move horizontally, after the slider compresses the spring or the slider is firmly adsorbed by the electromagnet 702, the base 701 can slide to ensure that the outer tube 2 can extend out of the opening of the housing 1.

[0069] Reference Figure 4 Furthermore, a round rod is provided at the bottom of the inner side of the housing 1, and another sliding block is slidably connected to the round rod. The sliding block has the same shape as the nut 502, and another supporting rod 503 is fixedly provided on the sliding block. The supporting rod 503 is also hinged to the wall of the outer cylinder 2. The round rod and the lead screw 501 are in the same horizontal plane, and the two are symmetrically arranged with respect to the outer cylinder 2. When the lead screw 501 drives the nut 502 to move, the sliding block also slides synchronously on the round rod.

[0070] It can be understood that the part where the connecting rod 706 is hinged to the outer cylinder 2 is close to the opening of the outer cylinder 2, and the parts where the two supporting rods 503 are hinged to the outer cylinder 2 are located in the middle of the outer cylinder 2 or close to the bottom of the outer cylinder 2. This arrangement facilitates the deflection of the outer cylinder 2 and the inner cylinder 3.

[0071] Reference Figure 5Another embodiment of the third driving device 5 includes a mounting frame 507 arranged at the bottom of the inner side of the housing 1, a rack 505 is slidably arranged on the mounting frame 507, the rack 505 is arranged horizontally, a gear 506 is arranged in the middle of the mounting frame 507, and the gear 506 is driven by the meshing of the gear 506 and the rack 505; the axle of the gear 506 is fixedly connected with a motor, and the motor is fixedly installed at the bottom of the inner side of the housing 1. During operation, the motor drives the gear 506 to rotate, and then drives the gear 506 to move linearly, and finally realizes the outer cylinder 2 to extend or retract into the housing 1. In order to prevent the rack 505 from slipping, limit blocks are provided at both ends of the rack 505. The reciprocating linear motion of the rack 505 is realized by the forward or reverse rotation of the gear 506. Similarly, when the gear 506 drives the rack 505 to transmit, the support rod 503 will drive the outer cylinder 2 to extend or retract into the housing 1, and at this time, the connecting rod 706 on the upper part of the outer cylinder 2 will drive the base 701 to move along the inner top of the housing 1. Secondly, in the same manner as the transmission of the lead screw 501 and the nut 502, in order to enhance the stability of the movement of the outer cylinder 2, a round rod and a sliding block structure are provided inside the outer cylinder 2, and the arrangement manner thereof is consistent with the above-mentioned manner.

[0072] Furthermore, a sealing ring 4 is provided between the opening edge of the outer tube 2 and the opening edge of the outer shell 1. The sealing ring 4 is a rubber ring or a corrugated hose. When the outer tube 2 does not extend out of the outer shell 1, the sealing ring 4 can play a role in waterproofing and dustproofing. When the outer tube 2 extends out of the outer shell 1, the sealing ring 4 can also play a role in connecting the opening of the outer shell 1 and the outer tube 2, thereby enhancing the stability of the outer tube 2.

[0073] An embodiment of the present invention: In this embodiment, the electromagnet 702 is connected to the washing machine program controller. During the washing program, the electromagnet 702 is not energized, and the rotating shaft 605 of the outer drum 2 and the inner drum 3 is in the horizontal direction. Before and after the washing program starts, the electromagnet 702 is energized to generate electromagnetic force on the magnetic body 704, so that the rotating shaft 605 of the outer drum 2 and the inner drum 3 forms an inclined angle in the horizontal direction, which is convenient for users to put in / take out clothes. Or, when the user chooses water-saving washing, during the washing program, the inclination angle of the outer drum 2 and the inner drum 3 is determined according to the detected load amount, and the corresponding current value is input at the electromagnet 702, thereby controlling the electromagnetic force so that the washing machine drum obtains the inclination angle. In this embodiment, when taking and placing clothes, the magnitude of the current flowing through the electromagnet 702 is fixedly set, and the magnitude of the current can at least enable the electromagnet 702 to be energized to tightly adsorb the magnetic body 704 and the electromagnet 702 together to form a fixed inclination angle, which is 15°.

[0074] Furthermore, after the outer drum 2 and the inner drum 3 are tilted, the third driver 504 is started, driving the lead screw 501 to rotate, and the lead screw 501 drives the nut 502 and the support rod 503 to move toward the opening of the outer shell 1. Since the outer drum 2 also moves outward synchronously at this time, the outer drum 2 will drive the connecting rod 706. Since the magnetic body 704 and the electromagnet 702 are firmly adsorbed, the connecting rod 706 will drive the base 701 to move outward together. When the outer drum 2 and the inner drum 3 extend out of the opening of the outer shell 1, the user can take and put clothes.

[0075] In another embodiment of the present application, the inclination angle of the outer drum 2 and the inner drum 3 is adjusted by controlling the magnitude of the current to change the electromagnetic force of the electromagnet 702 on the magnetic body 704 to attract the magnetic body 704 to move, and then the front end of the outer drum 2 is pulled up by the connecting rod 706 to adjust the inclination angle of the drum. The drum washing machine sets different optional drum inclination angles according to the current flowing through the electromagnet 702 of different gears. Due to the different magnitudes of the current, the electromagnetic force generated is also different. The magnetic body 704 is simultaneously subjected to the traction tension of the magnetic body 704 reset spring 705 and the electromagnetic force of the electromagnet 702. Under the action of the combined force, the distance between the magnetic body 704 and the electromagnet 702 is determined. When the electromagnetic force exceeds the traction tension of the magnetic body 704 reset spring 705, the magnetic body 704 moves toward the electromagnet 702 along the slide bar 703. At this time, the connecting rod 706 pulls up the front end of the outer drum 2, so that the rotating shaft 605 of the outer drum 2 and the inner drum 3 form an inclination angle in the horizontal direction. Therefore, the distance between the magnetic body 704 and the electromagnet 702 is different, and the tilt angle is also different. That is, the tilt angle adjustment of the outer cylinder 2 and the inner cylinder 3 can be achieved by controlling the current to change the electromagnetic force of the electromagnet 702 on the magnetic body 704.

[0076] Furthermore, when taking and placing clothes, the appropriate inclination angle of the outer drum 2 is selected according to factors such as the user's height and the model to meet the different needs of various users. In this embodiment, the inclination angles of the outer drum 2 and the inner drum 3 are provided with five optional gears of 5°, 15°, 30°, 35°, and 45°. Alternatively, four gears of 5°, 15°, 25°, and 35° are available, or three gears of 10°, 25°, and 40° are available. The purpose of facilitating users to put in / take out clothes can be achieved by selecting a suitable inclination angle of the outer drum 2 and the inner drum 3 within the range of 0 to 45°. In actual use, the outer drum 2 can be controlled to be pushed out first, and then the outer drum 2 can be controlled to deflect to prevent the outer drum 2 from moving by itself during the pushing process.

[0077] Another embodiment of the present invention is that this embodiment not only controls the inclination of the outer drum 2 and the inner drum 3 when taking out and putting clothes, but also controls the inclination angle of the outer drum 2 and the inner drum 3 according to the amount of clothes put into the washing machine during washing; for example, the less clothes put into the washing machine, the less water in the outer drum 2 and the inner drum 3, and the greater the inclination angle of the outer drum 2 and the inner drum 3. When there are more clothes, the more water in the outer drum 2 and the inner drum 3, and the smaller the inclination angle of the outer drum 2 and the inner drum 3. This embodiment can control the deflection angle of the outer drum 2 and the inner drum 3 according to the amount of clothes put into the washing machine when washing clothes, while reducing the water consumption. It can also ensure the washing effect, thereby achieving water-saving washing.

[0078] It should be noted that if the water inlet pipe and the water outlet pipe of the washing machine are connected to the outer drum 2, in order to cooperate with the deflection, movement and other actions of the outer drum 2 and the inner drum 3, the connection between the water inlet pipe, the water outlet pipe and the outer drum 2 also needs to be installed or a corrugated hose should be used to ensure that the water inlet pipe and the water outlet pipe will not be pulled off.

[0079] The present invention can realize the deflection of the outer drum 2 and the inner drum 3, and can also realize the pushing out of the outer drum 2 and the inner drum 3, and the two can work independently. The deflection of the outer drum 2 and the inner drum 3 can select a suitable deflection angle according to the amount of clothes to be washed, which can achieve the effect of water saving while ensuring the washing effect. When the outer drum 2 and the inner drum 3 extend out of the outer shell 1 and deflect upward, it is convenient for users to take and put clothes, and for users of different heights, the outer drum 2 and the inner drum 3 can be controlled to tilt at different angles, thereby improving the practicality of the washing machine.

[0080] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
