Description

Technical Field

[0001] This invention belongs to the field of washing machine technology, specifically relating to a drum washing machine and a method for moving the drum washing machine. Background Technology

[0002] Currently, drum washing machines have increasingly larger washing capacities, with 10 kg being the starting capacity. Spin speeds are also getting higher; 1200 RPM is no longer considered high, and 1400 RPM is not uncommon. With these improvements in specifications, the weight of the motor, casing, frame, and counterweights also increase, making the washing machine itself heavier and more difficult to move. Indoor transport is even more challenging because the packaging has been removed, easily leading to scratches on the floor or even injuries from crushing.

[0003] Especially for built-in washing machines, placing them inside cabinets is a challenge. For many users who value simplicity, the smaller the distance between the built-in washing machine and the cabinet, the better. Therefore, they purchase direct-drive washing machines with low vibration.

[0004] Currently, in order to facilitate the indoor movement of washing machines, especially their placement in cabinets, specialized moving devices using motors or manual operation have emerged, which are convenient to use; however, they are expensive, and the washing machine is moved too infrequently after installation, averaging less than once a year, making such a complex and costly structure completely unnecessary, resulting in extremely low cost-effectiveness.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] To address the aforementioned problems in the prior art, this invention proposes a drum washing machine that, by incorporating a movable rod, allows the washing machine to be moved while in its installed state by activating the spin-drying program and utilizing the vibration of the washing machine.

[0007] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0008] A drum washing machine, comprising:

[0009] Box;

[0010] The outer cylinder is located inside the box;

[0011] The inner cylinder is rotatably located inside the outer cylinder;

[0012] An electric motor, which drives the rotation of the inner cylinder;

[0013] A movable rod, which detachably connects the housing and the outer drum, and can move the washing machine by starting the spin-drying program when it is installed.

[0014] Furthermore, the housing has a front plate with a first mounting hole matching the moving rod, and a second mounting hole matching the moving rod is provided on the outer cylinder.

[0015] Furthermore, the first mounting hole is made at the lower left or lower right corner of the front panel.

[0016] Furthermore, it also includes a lint filter, with an inner groove provided in the lower right corner of the front plate, the lint filter being installed at the bottom of the inner groove, and the first mounting hole being opened at the bottom of the inner groove.

[0017] Furthermore, the movable rod has a movable rod body passing through the first mounting hole and a handle hinged to the front end of the movable rod body, the handle being located within the inner groove.

[0018] Furthermore, a locking groove for limiting the handle is provided on the side wall of the inner groove, and the end of the handle away from the moving rod is located in the locking groove.

[0019] Furthermore, the engaging groove has an arcuate portion centered on the first mounting hole and a flat portion that can be matched with the side of the handle.

[0020] Furthermore, the movable rod can be used to fix the box and outer drum during the transport packaging of the washing machine.

[0021] Furthermore, the first mounting hole is a through-hole.

[0022] Furthermore, the second mounting hole is either a threaded hole or a smooth hole.

[0023] Furthermore, it also includes a shock-absorbing component disposed between the housing and the outer cylinder, wherein the shock-absorbing component is in a partially or completely ineffective state when the moving rod is installed.

[0024] Based on the above-described drum washing machine, the present invention also provides a method for moving the washing machine. By setting a moving rod, the washing machine can be moved by starting the spin-drying program in its installed state, utilizing the vibration of the washing machine.

[0025] A method for moving the above-mentioned drum washing machine includes the following steps:

[0026] S10. Install the movable rod; install the movable rod onto the housing and outer cylinder;

[0027] S20. Select the spin-drying program and start it; After powering on the washing machine, select the spin-drying program and start it;

[0028] S30. Portable washing machine; the vibration of the outer drum is transmitted to the cabinet through the moving rod, and the washing machine is moved by utilizing the vibration of the cabinet and the force applied to the cabinet by the user to guide the direction of movement.

[0029] S40. After moving the lever into place, turn off the washing machine and then remove the lever.

[0030] Furthermore, after step S10, there is a step S11 to increase the weight of the washing machine by placing a weight in the inner drum to increase the weight of the washing machine and increase the vibration amplitude.

[0031] Furthermore, prior to step S20, there is a step S19 in which the moving rod is held to control the direction of movement of the washing machine.

[0032] Compared with the prior art, the advantages and positive effects of the present invention are as follows: By setting a movable rod, the housing and the outer drum are connected when the movable rod is installed, so that the shock-absorbing components between the housing and the outer drum are partially or completely ineffective; when the spin-drying program is started, the outer drum and the housing vibrate together, and by utilizing the force of the washing machine's vibration and by the force provided by the user to guide the movement of the washing machine, the movement of the washing machine can be easily realized, making the operation simple and convenient; the movable rod alone can realize the movement of the washing machine, making the structure simple and helping to reduce costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example

[0048] See Figures 1-8 This is the first embodiment of a drum washing machine proposed in this invention. The drum washing machine includes: a housing 10, an outer drum 20, an inner drum 30, and a moving rod 40. The outer drum 20 and the inner drum 30 are fitted inside the housing 10. The outer drum 20 is mounted inside the housing 10 via a shock-absorbing component 60. The outer drum 20 contains washing water. During the washing process, the inner drum 30 is rotated by a motor to clean the clothes. The washing machine vibrates during operation, especially during the spin-drying cycle, requiring high-speed rotation of the inner drum 30 to use centrifugal force to remove the water absorbed by the clothes. The shock-absorbing component 60 helps to reduce the vibration of the outer drum 20 and minimizes the transmission of vibration from the outer drum 20 to the housing 10, thus ensuring the stability of the housing 10.

[0049] To prevent the outer drum 20 from violently shaking and impacting the casing 10 during transportation, it is usually necessary to fix the outer drum 20 to the casing 10. Bolt holes 121 are made on the casing 10, and transport bolts are used to secure the outer drum 20 to the casing 10. For a more aesthetically pleasing appearance, the bolt holes 121 are located on the rear panel 12 of the casing 10, and threaded holes 121 matching the transport bolts are provided on the outer protruding frame of the outer drum 20. After the washing machine is transported to the user's home, the transport bolts must be removed before actual use; otherwise, the vibration of the outer drum 20 will be directly transmitted to the casing 10, causing significant vibration in the casing 10.

[0050] The present invention utilizes the large vibration of the outer drum 20 and the housing 10 when they are fixed or connected, especially during the high-speed spin-drying program. By using the vibration process, a certain force is applied to the washing machine, which can easily push or pull the washing machine in and out, thus realizing the movement of the washing machine.

[0051] In this embodiment, a movable rod 40 is also included, which is detachably and fixedly connected to the housing 10 and the outer drum 20. When the movable rod 40 is installed, that is, when the movable rod 40 is fixedly connected to the housing 10 and the outer drum 20, the washing machine's spin-drying program is started. At this time, the housing 10 will have a large high-frequency vibration, that is, the vibration amplitude is large and the frequency is high, which can easily move the washing machine. By setting a movable rod 40, when the movable rod 40 is installed, the cabinet 10 and the outer drum 20 are connected, causing the shock-absorbing component 60 between the cabinet 10 and the outer drum 20 to be partially or completely ineffective. When the cabinet 10 and the outer drum 20 are fixedly connected, meaning there is no relative freedom of movement between them, the shock-absorbing component 60 is completely ineffective. When the cabinet 10 and the outer drum 20 are connected, and only a portion of their relative movement is restricted, allowing relative movement in certain directions, the shock-absorbing component 60 is partially ineffective. When the spin-drying program starts, the outer drum 20, along with the cabinet 10, vibrates significantly. Utilizing the force of this vibration, and with the user providing force to guide the washing machine's movement, the washing machine can be easily moved. The operation is simple and convenient. The movable rod 40 enables the washing machine to be moved, resulting in a simple structure, dual functionality, and cost reduction.

[0052] See Figure 5 As shown, the casing 10 has a front panel 11, on which a first mounting hole 111 matching the moving rod 40 is provided, and on the outer drum 20, a second mounting hole 21 matching the moving rod 40 is provided. By providing the first mounting hole 111 on the front panel 11, the moving rod 40 can be installed and removed from the front of the washing machine, which is convenient for operation; because when the washing machine is placed, it must be against the wall. If it is set on the back panel 12, there will be no space to remove the moving rod 40 after it is moved into place, and the moving rod 40 cannot be installed when it needs to be moved again, especially when the washing machine is placed inside a cabinet, there is no space to remove and install the moving rod 40.

[0053] In this embodiment, a first mounting hole 111 is provided at the lower left or lower right corner of the front panel 11 to minimize the impact on the appearance of the washing machine. An inner groove 13 is provided at the lower right corner of the front panel 11, and the lint filter 90 is detachably mounted in the inner groove 13. Preferably, the first mounting hole 111 is located on the bottom of the inner groove 13, which is also the rear wall of the inner groove 13. Preferably, the first mounting hole 111 is located at the upper left corner of the bottom of the inner groove 13, and the plane containing the axis of the first mounting hole 111 and the axis of the filter 90 forms a plane at a 45° angle to the horizontal plane. A hinged cover 70 is attached to the inner groove 13. The cover 70 is normally closed. It is only opened when the lint filter 90 needs to be cleaned or the moving rod 40 needs to be disassembled or installed. This avoids the impact of opening the first mounting hole 111 on the appearance of the washing machine. Furthermore, the inner groove 13 has a concave structure, which helps to strengthen the structure and ensures that it can withstand the vibration force transmitted by the outer drum 20. It also helps to transmit the vibration of the outer drum 20 in the left and right directions to the cabinet 10, which is conducive to the movement of the cabinet 10.

[0054] There are multiple implementation methods for connecting the movable rod 40 to the first mounting hole 111 and the second mounting hole, and different implementation methods determine the degree of freedom of movement between the outer drum 20 and the housing 10. In the first implementation method, the second mounting hole on the outer drum 20 is a threaded hole, and the rear end of the movable rod 40 is provided with an external thread that matches the threaded hole; the first mounting hole 111 is a through hole, and the movable rod 40 is provided with a stop edge that stops in front of the first mounting hole 111. After the movable rod 40 is installed and fixed, the movable rod 40 is fixed to the outer drum 20. The movable rod 40 is restricted in its vertical and horizontal movement within the first mounting hole 111, and its backward movement is also limited, but its forward movement is not limited; that is, the shock absorption component 60 is still effective in the forward direction. After the movable rod 40 is installed, it can be used to fix the housing 10 and the outer drum 20 during the transportation of the washing machine, which helps to increase the firmness of the fixation of the housing 10 and the outer drum 20. In the second embodiment, the movement freedom of the moving rod 40 within the first mounting hole 111 is restricted, thus rendering the shock-absorbing components 60 completely ineffective. In the third embodiment, the second mounting hole on the outer cylinder 20 can be a through hole, and the first mounting hole 111 can be a through hole extending from front to back. This means that the moving rod 40 has a degree of freedom in the front-back direction relative to the outer cylinder 20, and vibrations in the front-back direction on the outer cylinder 20 are not transmitted to the housing 10, thus keeping the moving rod 40 stationary relative to the housing 10.

[0055] When the washing machine is moved, due to its considerable weight, even using the vibration force of the washing machine, such as pushing the cabinet 10 to achieve synchronous movement of the entire machine, requires a significant force. Specifically, when the washing machine needs to be moved, the moving rod 40 is installed into the first mounting hole 111 and the second mounting hole, thus fixing the outer drum 20 to the cabinet 10. Then, the spin-drying program is started, and the motor drives the inner drum 30 to rotate at high speed, causing the washing machine to vibrate violently. A force is then applied to guide the movement of the washing machine, that is, a pushing or pulling force is applied to the cabinet 10, and the upward vibration force of the washing machine is used to move it.

[0056] In this embodiment, see Figure 8 As shown, the moving rod 40 has a moving rod body 41 passing through the first mounting hole 111 and a handle 42 hinged to the front end of the moving rod body 41. The handle 42 facilitates the application of force to the washing machine, making it easier to control the direction of movement, especially when the washing machine is placed inside a cabinet. The hinged connection between the handle 42 and the moving rod body 41 prevents the handle 42 from extending into the cabinet 10 after packaging, as the handle 42 is located within the inner groove 13. Furthermore, when moving the washing machine, the user can grasp the handle 42 to control its direction of movement. The hinged connection between the handle 42 and the moving rod body 41 also allows vibrations transmitted from the moving rod body 41 to the handle 42 to be buffered by the relative movement between the handle 42 and the moving rod body 41, providing a comfortable and secure grip for the user.

[0057] A locking groove 131 for limiting the handle 42 is provided on the side wall of the inner groove 13. The end of the handle 42 away from the moving rod 41 is located in the locking groove 131. The locking groove 131 is located on the rear side of the front plate 11. When the moving rod 40 is used as a fixed part of the transport packaging, after the moving rod 40 is installed, the moving rod 41 passes through the first mounting hole 111 and the second mounting hole. The included angle between the handle 42 and the moving rod 40 is greater than or equal to 90°, and the lower end of the handle 42 is located in the locking groove 131. The degree of freedom of movement of the handle 42 in the front-back direction is limited, that is, it is locked, so that the moving rod 40 is fixed to the box 10.

[0058] The engaging groove 131 has an arcuate portion 1311 centered on the first mounting hole 111 and a flat portion 1312 that can be matched with the side of the handle 42. The arcuate portion 1311 and the flat portion 1312 are connected. The side of the arcuate portion 1311 away from the flat portion 1312 is connected to the side wall of the inner groove 13. The handle 42 can only enter and exit the engaging groove 131 from the end where the arcuate portion 1311 is connected to the side wall of the inner groove 13, which helps to ensure the stability of the handle 42 engaging in the engaging groove 131. Preferably, the flat portion 1312 is vertically oriented. The inner groove 13 is a cylindrical groove, and the length of the handle 42 is greater than the radius of the inner groove 13 and less than the diameter of the inner groove 13. Example

[0059] This embodiment is the first method for moving drum-type laundry detergent, and the structure can be the same as that of the first embodiment.

[0060] See Figure 9 As shown, a method for moving the above-mentioned drum washing machine includes the following steps:

[0061] S10. Install the movable pole 40;

[0062] Specifically, the moving rod 40 is installed on the housing 10 and the outer cylinder 20; the cover 70 is opened, and the moving rod 40 is inserted from the front into the first mounting hole 111 and installed into the second mounting hole.

[0063] S19. The hand-held movement lever 40 is used to control the direction of movement of the washing machine;

[0064] Specifically, hold the handle 42 with your hand and rotate the handle 42 relative to the moving rod 41 to reach a comfortable grip angle.

[0065] S20. Select the dehydration program and start it;

[0066] Specifically, after powering on the washing machine, select the spin-drying program and start it; after starting, the motor drives the inner drum 30 to rotate at high speed, so that the vibration of the inner drum is transmitted to the outer drum 20, and further transmitted to the cabinet 10 through the moving rod 40, so that the cabinet 10 has a large vibration.

[0067] S30. Portable washing machine;

[0068] Specifically, the vibration of the outer drum 20 is transmitted to the cabinet 10 through the moving rod 40. The vibration of the cabinet 10 is mainly achieved by taking advantage of the moment when the bottom of the cabinet 10 leaves the ground. At the same time, the user applies force to the cabinet 10 to guide the direction of movement, thereby moving the washing machine.

[0069] S40. After moving the lever into place, turn off the washing machine, and then remove the moving lever 40. Example

[0070] This embodiment is a second moving method of the first embodiment, and the structure can be the same as that of the first embodiment; the difference between this embodiment and the first moving method is that it has a step of increasing the weight of the washing machine.

[0071] See Figure 10 As shown, a method for moving the above-mentioned drum washing machine includes the following steps:

[0072] S10. Install the movable pole 40;

[0073] Specifically, the moving rod 40 is installed on the housing 10 and the outer cylinder 20; the moving rod 40 is inserted from the front into the first mounting hole 111 and installed into the second mounting hole.

[0074] S11. Increase the weight of the washing machine;

[0075] Specifically, open the door 80 and place weight-adding items into the inner drum 30. These can be clothes or other soft-outer items that prevent damage to the washing machine, in order to increase the weight of the washing machine and increase the vibration amplitude.

[0076] S19. The hand-held movement lever 40 is used to control the direction of movement of the washing machine;

[0077] Specifically, hold the handle 42 with your hand and rotate the handle 42 relative to the moving rod 41 to reach a comfortable grip angle.

[0078] S20. Select the dehydration program and start it;

[0079] Specifically, after powering on the washing machine, select the spin-drying program and start it; after starting, the motor drives the inner drum 30 to rotate at high speed, so that the vibration of the inner drum is transmitted to the outer drum 20, and further transmitted to the cabinet 10 through the moving rod 40, so that the cabinet 10 has a large vibration.

[0080] S30. Portable washing machine;

[0081] Specifically, the vibration of the outer drum 20 is transmitted to the cabinet 10 through the moving rod. The vibration of the cabinet 10 is mainly taken advantage of the moment when the bottom of the cabinet 10 is lifted off the ground. At the same time, the user applies force to the cabinet 10 to guide the direction of movement, so as to realize the movement of the washing machine.

[0082] S40. After moving the lever into place, turn off the washing machine, and then remove the moving lever 40.
