Description

Technical Field

[0001] This invention belongs to the field of washing equipment fixing technology, specifically relating to a fixing device for washing equipment and a washing equipment having the fixing device. Background Technology

[0002] In everyday life, most washing machines, shoe washers, dishwashers, and other laundry appliances are placed on four feet that contact the ground or countertop. However, this conventional placement method faces several potential problems in actual use. Firstly, if the ground is uneven, the equipment will struggle to maintain stability during operation. Secondly, uneven distribution of the internal load, such as laundry piling up on one side of the drum, will disrupt the balance. Furthermore, the rubber pads at the feet, crucial for cushioning and stability, will gradually age and lose elasticity over time, becoming ineffective at absorbing vibrations. Additionally, a sudden malfunction in the internal balance adjustment components will also prevent the equipment from operating smoothly.

[0003] With these adverse factors combined, when the washing machine starts its washing and spin-drying cycle and rotates at high speed, strong vibrations follow. Once the vibration frequency approaches the machine's natural frequency and reaches the resonance point, a resonance effect is triggered. At this point, the entire machine will shift significantly. The dangers of this shift should not be underestimated. It can not only pull on the power cord, causing it to deviate from its initial position and leading to abnormal circuit connections and increased risk of electric leakage, but it can also cause the machine to collide with surrounding objects during the shift, damaging these items and creating chaos in the user's home environment. More seriously, if the machine is placed on a countertop, the combined impact of strong vibrations and shifting could cause it to fall off the countertop, resulting in serious damage, economic losses for the user, and threatening safety.

[0010] In some embodiments of this application, the rotating adjustment plate is provided with a mounting shaft for mounting the reset elastic member. The reset elastic member has a spiral portion sleeved on the outside of the mounting shaft and two push legs that are respectively connected to the upper and lower ends of the spiral portion and extend outward.

[0011] In some embodiments of this application, the rotating adjustment plate is mounted on a fixed base and is rotatable left and right. A rotating shaft is provided between the rotating adjustment plate and the fixed base, and the rotating shaft is located behind the mounting shaft.

[0013] In some embodiments of this application, a limiting structure for limiting the relative movement of the locking plate is provided between the groove wall and the locking plate. The limiting structure has a limiting groove formed on one of the groove wall and the locking plate, and a limiting post provided on the other of the groove wall and the locking plate and matched with the limiting groove. The limiting post is located relatively movable within the limiting groove.

[0014] In some embodiments of this application, the limiting groove is inclined backward in a direction away from the avoidance groove; two limiting structures are provided between the groove wall and the locking plate, arranged front to back.

[0015] In some embodiments of this application, the second fastener has a mounting plate fixed to the lower end of the housing and a locking post extending downward.

[0016] In some embodiments of this application, the locking pin has a rearward movable state and a forward movable locked state between the two locking plates.

[0031] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0032] See Figures 1-10 This is an embodiment of a fixing device for a washing machine proposed in this invention. The fixing device 100 includes a first fixing member 10 and a second fixing member 20. The washing machine 200 has a housing with four feet at its lower end. The first fixing member 10 is fixed to a fixing surface 300 at the rear of the washing machine 200, and the second fixing member 20 is fixed to the lower end of the housing of the washing machine 200. Through the cooperative installation of the first fixing member 10 and the second fixing member 20, the washing machine 200 can be fixed from multiple directions, ensuring the washing machine 200 remains stable during operation and enhancing equipment stability.

[0033] Specifically, the first fixing member 10 has a fixing seat 11 fixed on the fixing surface 300, a rotatable rotating adjustment plate 12 mounted on the fixing seat 11, and a locking plate assembly 13 that cooperates with the second fixing member 20 to achieve locking. The rotating adjustment plate 12 is rotatably mounted on the fixing seat 11. According to the specific position and angle requirements of the washing equipment 200 during actual installation, the rotating adjustment plate 12 can be adjusted by rotating and moving when cooperating with the second fixing member 20, which enhances the adaptability of the entire fixing device 100 and simplifies installation and positioning; it also achieves flexible fixing of the washing equipment 200. Through the rotating adjustment plate 12, it can swing left and right within a certain range. When the washing equipment 200 has a large amplitude vibration, it can absorb energy through swinging, which plays a shock absorption role and avoids large forces acting on the fixing device 100, thus preventing damage to the cabinet or fixing device.

[0034] The locking plate assembly 13 has two movable locking plates 131 mounted on the rotating adjustment plate 12, and the second fixing member 20 is fixed between the two locking plates 131. The double locking plate structure allows for stable clamping of the second fixing member 20 from both sides, making the fixation more secure and reliable. Furthermore, the movable design of the locking plates 131 facilitates the installation of the second fixing member 20 between the two locking plates 131, improving the convenience and reliability of the fixing device 100 in terms of connection and fixation. The structural design of the fixing device 100 is relatively simple and clear, with clear connections between the various components. In actual installation, no complex installation techniques or professional skills are required, facilitating subsequent maintenance and disassembly.

[0035] In some embodiments of this application, the locking plate assembly 13 further includes a reset elastic member 132 for pushing the two locking plates 131 closer together to reset. The reset elastic member 132 has two pushing legs 1322 that respectively cooperate with the two locking plates 131. When the second fixing member 20 is moved backward and installed between the two locking plates 131, the second fixing member 20 can push the two locking plates 131 away from each other, so that the second fixing member 20 has space to move backward. Then, the reset elastic member 132 pushes the two locking plates 131 closer together to reset, preventing the second fixing member 20 from moving forward and disengaging from the locking plates 131, which is beneficial for a firm fixation. When installing the second fixing member 20, it needs to be moved backward and installed between the two locking plates 131. The reset elastic member 132 pushes the two locking plates 131 away from each other, automatically making room for the second fixing member 20 to move backward, and then quickly and automatically resets. This adaptive space adjustment mechanism greatly simplifies the installation process, eliminating the need to manually and precisely adjust the spacing of the locking plates 131, making the installation process more convenient and efficient. It also reduces the stringent requirements for the processing and installation accuracy of each component, thus reducing the overall installation difficulty. The reset elastic element 132 engages with two locking plates 131 via two push legs 1322. The reset elastic element 132 promptly pushes the two locking plates 131 closer together, thus firmly clamping the second fixing member 20. This effectively prevents the second fixing member from moving forward and disengaging from the locking plates due to external forces or equipment vibrations, ensuring the stability of the connection between the first fixing member 10 and the second fixing member 20. This allows the entire fixing device 100 to continuously and stably fix the washing equipment 200. During the operation of the washing equipment 200, vibrations and shaking occur continuously. The reset elastic element 132, with its elastic properties, consistently applies a force to the locking plates 131, bringing them closer together, maintaining a continuous clamping force on the second fixing member 20. It prevents loosening due to repeated interference during equipment operation, thus maintaining a secure and stable fixation for a long time.

[0036] In some embodiments of this application, the locking plate 131 has a locking plate body 1311 arranged parallel to the rotation adjustment plate 12, an upper edge portion 1312 extending upwardly along the rear end of the locking plate body 1311, and a rear edge portion 1313 extending backwardly along the upper end of the upper edge portion 1312. The upper edge portion 1312 and the rear edge portion 1313 form a push groove that cooperates with the push leg 1322. The push leg 1322 provides the locking plate 131 with a forward and inward torque. The push slot provides a precise positioning space for the push leg 1322, allowing it to accurately engage with the reset elastic element 132 during operation. This prevents positional shifts or detachment of the push leg 1322 due to vibrations or other factors during equipment operation, ensuring the stability and reliability of the fit between the reset elastic element 132 and the locking plate 131. The reset elastic element 132 can continuously and effectively push the locking plate 131 closer together to reset, thus firmly securing the second fixing element 20. The upper edge 1312 and the rear extension 1313 enhance the overall strength and rigidity of the locking plate 131, enabling it to better withstand the thrust from the reset elastic element 132 and the thrust during installation of the second fixing element 20. This helps maintain the integrity and stability of the entire locking plate assembly structure over the long term.

[0037] In some embodiments of this application, a mounting shaft 133 for mounting the reset elastic member 132 is provided on the rotary adjustment plate 12. The reset elastic member 132 has a spiral portion 1321 sleeved on the outside of the mounting shaft 133 and two push legs 1322 connected to the upper and lower ends of the spiral portion 1321 and extending outward. The mounting shaft 133 provides reliable support and fixation for the reset elastic member 132. The spiral portion 1321 is tightly sleeved on the mounting shaft 133, ensuring that the reset elastic member 132 is always in a stable installation state throughout the entire use process, continuously and effectively providing a reset thrust to the locking plate 131, maintaining the clamping effect of the two locking plates 131 on the second fixing member 20, thereby ensuring the stability of the overall structure of the fixing device 100.

[0038] In some embodiments of this application, the rotating adjustment plate 12 is mounted on the fixed base 11 and can rotate left and right. A rotating shaft 14 is provided between the rotating adjustment plate 12 and the fixed base 11, and the rotating shaft 14 is located behind the mounting shaft 133. When actually installing the second fixing member 20, it is difficult to guarantee that it can be precisely aligned with the locking plate assembly 13 in the front-back direction and without any deviation in the left-right direction each time. By setting a rotating adjustment plate that can rotate left and right, when there is a certain range of left-right deviation, the rotational movement of the rotating adjustment plate enables the smooth installation of the second fixing member 20; this greatly improves the error tolerance of the installation process, reduces the stringent requirements for installation accuracy, and makes the installation operation simpler and easier.

[0039] In some embodiments of this application, the rotating adjustment plate 12 extends forward and is horizontally positioned. A clearance groove 121 for avoiding the second fixing member 20 is provided on the rotating adjustment plate 12, and the clearance groove 121 has a front opening. Two locking plates 131 are respectively disposed on the left and right walls 122 of the clearance groove 121, and the locking plates 131 extend inward into the clearance groove 121. When installing the second fixing member 20, the operator can easily guide the second fixing member 20 to a suitable position within the clearance groove 121 along the front opening, allowing it to accurately engage with the two locking plates 131 located on the left and right walls of the clearance groove 121. This eliminates the need for complex alignment operations, greatly simplifying the installation process and improving installation efficiency. When the second fixing member 20 enters the clearance groove 121, it can directly interact with the locking plates 131 on the side groove walls 122. This integrated layout reduces unnecessary spacing and connection links between components, enhances the overall integrity and structural stability of the fixing device, and allows the fixing device 100 to function more harmoniously. The two locking plates 131 are located on the left and right groove walls of the clearance groove, and they can tightly clamp the second fixing member 20 located within the clearance groove 121 from both sides, forming a stable fixing structure. During equipment operation, when faced with external forces such as vibration and shaking, this clamping from both sides can effectively limit the horizontal displacement of the second fixing member 20, preventing it from loosening or detaching from the locking plates, and ensuring the firmness of the connection between the first fixing member 10 and the second fixing member 20.

[0040] In some embodiments of this application, a limiting structure is provided between the groove wall 122 and the locking plate 131 to limit the relative movement of the locking plate 131. The limiting structure limits the direction and distance of movement of the locking plate 131 relative to the groove wall 122. The limiting structure has a limiting groove 1314 formed on the locking plate 131 and a limiting post 1221 provided on the groove wall 122. The limiting post 1221 is matched with the limiting groove 1314 and is movably located within the limiting groove 1314. The two locking plates 131 can always be maintained at a suitable distance and angle by relying on the limiting structure, so as to better clamp and fix the second fixing member 20, maintain the functional state of the fixing device 100 at the beginning of its design, and avoid problems such as fixing failure caused by changes in the relative position of the components. When the second fixing member 20 needs to be installed, the locking plate 131 can move appropriately and correctly under the constraint of the limiting post 1221 and the limiting groove 1314 to ensure that the clamping operation of the second fixing member 20 can be successfully completed.

[0041] In other embodiments of this application, the limiting structure may also be a limiting groove formed on the groove wall 122, and a limiting post provided on the locking plate 131.

[0042] In some embodiments of this application, the limiting groove 1221 is inclined backward in the direction away from the avoidance groove 121; two limiting structures are provided between the groove wall 122 and the locking plate 131, which facilitates the smooth movement of the locking plate 131 and further limits the movable range of the locking plate 131.

[0043] In some embodiments of this application, the second fixing member 20 has a mounting plate 21 fixed to the lower end of the housing and a locking post 22 extending downward. The locking post 22 has a rearward movable state and a forward moving locked state between the two locking plates 131. When the locking post 22 moves backward, it pushes the two locking plates 131 away from each other, allowing the locking post 22 to move forward and be installed between the two locking plates 131, making the installation process simple and smooth, effectively improving installation efficiency and reducing installation difficulty. When the locking post 22 has a tendency to move forward, it is blocked by the two locking posts 22, forming a stable locking structure; effectively limiting the forward movement of the locking post 22, thereby preventing the second fixing member 22 from detaching from between the two locking plates, and ensuring the firmness of the connection between the first fixing member 10 and the second fixing member 20.

[0044] In some embodiments of this application, a row of locking teeth 1315 that cooperate with the locking pin 22 is provided on the side of the two locking plates 131 that are close to each other. The locking pin 22 has two pushing surfaces 221 that are far apart in the forward direction and a locking surface 222 that extends inward along the front end of the pushing surfaces 221. The locking teeth 1315 on the left and right locking plates 131 are arranged opposite each other. When the locking pin 22 moves backward, the two pushing surfaces 221 respectively contact the pair of locking teeth 1315 arranged opposite each other on the two locking plates 131. The pushing surfaces 221 contact the pushing mating surfaces 13151 on the front side of the locking teeth 1315 and move relative to each other, so that the locking plates 131 move outward and backward, so that the locking pin 22 moves backward through the locking teeth 1315. Then, under the action of the reset elastic member 132, the locking plates 131 are reset. The locking pin 22 can continue to move backward through the next locking tooth 1315. When the locking pin 22 moves forward, the locking surface 222 is blocked by the locking mating surface 13152 behind the locking tooth 1315, preventing it from moving forward.

[0045] In some embodiments of this application, the locking tooth 1315 has a front pushing engagement surface 13152 and a rearward locking engagement surface 13152. The pushing engagement surface 13152 is inclined inward in the rearward direction. When the locking pin 22 is inserted between the two locking plates 131 in the rearward direction, the pushing engagement surface 13151 can smoothly engage with the pushing surface 221 on the locking pin 22. The locking engagement surface 13152 is arranged in the left-right direction, or the locking engagement surface 13152 is inclined forward in the outward direction. The locking mating surface 13152 is arranged parallel to the locking surface 222. When the locking pin 22 moves forward, it enters a movable locking state. The locking mating surface 13152 and the locking surface 222 can fit tightly together, forming a stable and large-area contact, maximizing the locking effect and effectively preventing the locking pin 22 from shifting forward when subjected to vibrations, shaking, or other external forces generated by equipment operation. This ensures the firmness of the fixed connection between the second fixing member 20 and the locking plate 131. Each locking tooth 1315 has a pushing mating surface 13151 and a locking mating surface 13152. When a row of locking teeth 1315 engages with the locking pin 22, the pushing mating surfaces 13151 of multiple teeth work together to help the locking pin 22 to be smoothly positioned during installation. The locking mating surfaces 13152 of multiple teeth can engage with the locking surfaces 222 of the locking pin 22 respectively, forming a "multiple insurance" fixing structure in the locking state. When it is necessary to disassemble the first fixing member 10 and the second fixing member 20, the locking pin 22 needs to be moved upward to disengage from the locking member 131.

[0046] In some embodiments of this application, the fixing base 11 has a vertically arranged fixing plate 111 and a horizontally arranged base plate 112. The vertical fixing plate 111 can be easily and firmly connected to the fixing surface 300 behind the washing equipment 200, ensuring the vertical stability of the fixing base 111 itself. The horizontal base plate 112 provides a horizontal bearing surface for the hinge of the rotating adjustment plate 12, so that it is not overly restricted by the surrounding space during rotation adjustment, and it is easy to cooperate with the second fixing member 20. The rotating adjustment plate 12 is hinged on the base plate 112. The locking mating surface 13152 is inclined forward in the outward direction to ensure the locking effect. The included angle between the locking mating surface 13152 and the fixing plate 111 is 4° to 8°. Preferably, the included angle between the locking mating surface 13152 and the fixing plate 111 is 5°; the length of the locking mating surface 13152 is 4mm. The fixing plate 111 is fixed to the fixing surface 300, which can be a wall.
