Abstract
Description
Technical Field
[0001] The utility model specifically relates to the technical field of washing machines, and particularly to an auxiliary bracket for a washing machine without a counterweight. Background Art
[0002] Counterweights are assembled on the drum of a drum washing machine; during the operation of the washing machine, the inner drum rotates at a high speed. If the center of gravity is unstable, violent shaking will occur, which will not only affect the normal operation of the washing machine, but may also damage the components of the washing machine and even cause damage to the surrounding environment. The counterweights are usually installed at the bottom or side of the washing machine. By increasing the weight of specific parts of the washing machine, the center of gravity of the washing machine is kept at a relatively stable position, so as to ensure that the washing machine can remain stable in various working states; when the inner drum of the washing machine rotates, centrifugal force will be generated, causing vibration. The existence of the counterweights can balance this centrifugal force and reduce the amplitude of vibration. Especially in the high-speed dehydration stage, the rotation speed of the inner drum is very fast, and the vibration will also increase accordingly, and the role of the counterweights is more obvious.
[0003] However, the use of counterweights will increase the weight of the washing machine, making it relatively heavy and inconvenient to carry; in particular, the counterweights are fixed on the top and both sides of the drum, and the four corners are hoisted by springs;
[0004] After long-term use, the springs will produce elastic fatigue, and under the pressing of the counterweights, the center of gravity of the drum will shift downward, resulting in an eccentric situation when the drum rotates. Therefore, abnormal noises or large overall vibrations or jumping of the washing machine will occur during the operation of the washing machine. Summary of the Utility Model
[0005] The purpose of the utility model is to provide an auxiliary bracket for a washing machine without a counterweight, using a spring as a tensile member at the bottom for traction, and adjusting the upper end of the drum through a tension adjusting member to make up for the defect of spring elastic fatigue, so as to ensure the uniqueness of the axis when the drum rotates, and remove the use of counterweights, thus realizing the lightweight design of the washing machine, so as to solve the technical problems raised in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Please refer to Figures 1-5 , in the embodiment of the present utility model, an auxiliary bracket for a washing machine without a counterweight includes a washing machine drum 1 disposed inside the outer cylinder 2, wherein the outer cylinder 2 is fixed to the rear shell 3 by bolts; the washing machine drum 1 is rotatably connected to the outer cylinder 2 through a slip ring, a transmission shaft is provided at the rear end of the washing machine drum 1, and the transmission shaft is installed in cooperation with the rear shell 3 through a bearing; and the transmission shaft also penetrates to the outside of the rear shell 3 and is installed in cooperation with a pulley 4;
[0027] Tension springs 6 are buckled on both sides of the outer cylinder 2; the lower ends of the tension springs 6 are buckled to the hanging buckles 8; tension adjustment members 10 for upward lifting are also provided on both sides of the outer cylinder 2.
[0028] Specifically, the hanging buckle 8 is welded to one side of the fixed bottom plate 7; and feet 5 are also fixed on the fixed bottom plate 7; the feet 5 are movably connected to the rear shell 3 through a rotating shaft.
[0029] By adopting the above technical solution, when in use, the tension springs 6 buckled on both sides of the outer cylinder 2 can exert a downward pulling force on the outer cylinder 2, and the tension adjusting member 10 can exert an upward pulling force on the outer cylinder 2, ensuring that the washing machine drum 1 inside the outer cylinder 2 has a stable axis when rotating; and both ends of the tension adjusting member 10 are hung and connected by hooks. Coupled with the setting of the tension springs 6, the vibration conduction during the rotation of the washing machine drum 1 can be reduced, thereby achieving the mute effect of the washing machine.
[0030] In this embodiment, the lower end of the tension adjusting member 10 is buckled on the first buckle rod 9. Both ends of the first buckle rod 9 are inserted into the outer cylinder 2 and locked and fixed by nuts; and the upper end of the tension adjusting member 10 is buckled on the second buckle rod 11; both ends of the second buckle rod 11 are fixed to the hanging rod 13.
[0031] By adopting the above technical solution, the connection with the first buckle rod 9 and the second buckle rod 11 is carried out by buckling, which simplifies the installation method of the tension adjusting member 10, has a simple structure and is convenient for assembly. Especially when repairing or cleaning the washing machine, the disassembly and assembly are more convenient.
[0032] In this embodiment, there are two hanging rods 13, and a cross brace 12 is fixed between the two hanging rods 13; through holes are provided on the cross brace 12 and the hanging rods 13, and are fixed to the washing machine shell by bolts.
[0033] By adopting the above technical solution, the cross brace 12 and the hanging rods 13 are fixed to the washing machine shell, which can play a role in hoisting and fixing the outer cylinder 2 and ensure the stability of the washing machine drum 1 during rotation.
[0034] In this embodiment, the tension adjusting member 10 includes a two-way locking device 101, and a forward screw rod 102 is threadedly connected to the upper end of the two-way locking device 101, and a reverse screw rod 103 is threadedly connected to the lower end of the two-way locking device 101.
[0035] When the traditional spring is used for a long time, its elastic fatigue will occur, resulting in a decrease in the tensile force of the spring. Therefore, we set the elastic force of the tension spring 6 to be twice the traditional tensile force, and then screw the forward screw rod 102 and the reverse screw rod 103 into the two-way locking device 101 to increase their cooperation. When the elastic force of the tension spring 6 produces elastic fatigue, rotate the forward screw rod 102 and the reverse screw rod 103 out of the two-way locking device 101 to reduce the pulling force on the tension spring 6, thereby ensuring the stability of the washing machine drum 1, and the service life of the tension spring 6 is doubled compared with the traditional spring.
[0036] The working principle of the present utility model is as follows: When in use, the tension springs 6 buckled on both sides of the outer cylinder 2 can apply a downward pulling force on the outer cylinder 2, and the tension adjusting member 10 applies an upward pulling force on the outer cylinder 2 to ensure that the washing machine drum 1 inside the outer cylinder 2 has a stable axis during rotation; moreover, both ends of the tension adjusting member 10 are hung and connected by hooks, and with the arrangement of the tension springs 6, the vibration conduction during the rotation of the washing machine drum 1 can be reduced, thereby achieving the silent effect of the washing machine.
[0037] Set the elastic force of the tension spring 6 to be twice the traditional tension, and then screw the forward lead screw 102 and the reverse lead screw 103 into the two-way locking device 101 to increase their fit. When the elastic force of the tension spring 6 generates elastic fatigue, rotate the forward lead screw 102 and the reverse lead screw 103 out of the two-way locking device 101 to reduce the pulling force on the tension spring 6, thereby ensuring the stability of the washing machine drum 1, and the service life of the tension spring 6 is doubled compared to the traditional spring.
