Description

Absorber device of drum machine cleaner

The present invention relates to a shock absorber of a drum washing machine, and more particularly, to a shock absorber of a drum washing machine, which is capable of absorbing and alleviating shock and vibration generated in a tub according to rotation of a drum during a dehydration stroke of a commercial drum washing machine or a water washing machine. Relates to a device.

In general, a washing machine is a household washing machine that receives washing water and repeatedly performs operations such as washing, rinsing, dehydration, and drying, and a large amount of washing water and laundry are put in a large container (drum). The operation of dropping laundry is repeated, and the drum washing machine is distinguished from a drum washing machine for a business that performs washing by the impact applied to the laundry. At this time, the drum washing machine has been applied for a lot of technical information about extending the life of the device by absorbing and mitigating the vibration of the motor generated when rotating the large drum so that noise and vibration is not transmitted to the outside of the main body.

1 is a state of use equipped with a shock absorber of the drum washing machine according to the prior art.

As shown, the drum 2 in the tub 1 has a rotational axis (not shown) of the drum 2 through the belt 4 by a power driven by a motor 5 mounted below the tub 1. It is rotated by being transmitted to the pulley (3) connected to drive the laundry, and the laundry inside the drum 2 is rotated at an angle of 120 ° inside the drum (2) while the laundry inside the drum (2) is rotated simultaneously with the rotation of the drum (2). After being raised to a certain height inside the drum 2 by the three water flow adjusting devices arranged, it is dropped, and the laundry is knocked by being hit by the drum 2 when the laundry falls.

Detergent pump (A) formed at the bottom of the frame (7) for holding the above-described tub (1) fixed to receive the solvent, which is a washing oil, and pumped from the detergent container (A) due to the drive of the detergent circulation pump (B) After the primary detergent filter (C) and the detergent passing through the primary detergent filter (C) to filter the primary filter by its own filter (for example, carbon) to the secondary filter by the same method and then the drum ( 2) It is provided with a secondary detergent filter cylinder (D) which is formed to communicate with the primary detergent filter cylinder (C) so as to supply the inside.

In addition, the other end of the shock absorbing spring (6) is fixed to one end of the upper end of the tub (1) in order to absorb and mitigate the shock, vibration and noise generated in the tub (1) during the dehydration stroke of the laundry. It is fixed to 7), the other end of the shock absorber 8 is fixed to the frame 7, one end of which is fixed to the lower outer periphery of the tub (1).

The aforementioned drum 2 is formed of stainless material to prevent corrosion, and an automatic balancer is built in to reduce vibration and noise generated when the drum 2 rotates due to the driving of the driving means. A plurality of small holes are formed in the circumferential direction at the side of the) so that the laundry flows inside the drum 2, and the wash water in the tub 1 can flow into the drum 2.

Therefore, since the laundry is washed by the fall of the laundry inside when the drum 2 is rotated, the damage of the laundry due to the twisting of the laundry generated during the washing in a general household washing machine is prevented. Washing is possible.

However, the shock, vibration and noise generated in the tub 1 due to the rotation of the drum 2 during dehydration may not be properly absorbed and alleviated by the shock absorber 8 mounted on the lower part of the tub 1, thereby reducing its function. Due to the deterioration of the durability of the product has a problem of shortening the service life. That is, in the shock absorber 8 described above, there is a problem in that the shock and vibration acting downward on the tub 1 when the drum 2 is rotated (when the compression drive of the shock absorber 8 is operated) cannot be sufficiently coped. .

In addition, by assembling and manufacturing them due to an increase in the number of parts corresponding to separately mounting the shock absorbing spring 6 and the shock absorber 8 separately to absorb and alleviate the shock and noise generated in the upper and lower parts of the tub 1 described above. The workability is poor.

On the other hand, in order to prevent the drum washing machine from flowing due to the shock and vibration generated in the tub (1) during dehydration, the anchor bolt is embedded in the bottom surface to fasten the lower side of the frame (7). You have the problem of being limited.

Accordingly, an object of the present invention is to install a shock absorber and a compression spring coaxially between the tub of a commercial drum washing machine or a water washing machine and a frame supporting the same, so as to absorb the shock and vibration, the shock generated when driving the washing machine, It is to provide a shock absorber of the drum washing machine to completely absorb and mitigate noise and vibration to improve durability.

Another object of the present invention is to provide a shock absorber of a drum washing machine, which is provided with a shock absorbing member for absorbing and mitigating shock and vibration generated when the washing machine is driven only to the lower side of the tub, thereby greatly improving workability of assembling and manufacturing the washing machine. It is.

It is integrally mounted and is generated in the tub 11 when dewatering between the brackets 15 and 16 formed in the four corners of the frame 14 for supporting the tub 11 and the brackets 12 and 13 of the tub 11. The shock absorbing member to absorb the shock and vibration to be coaxially mounted, the shock absorbing member is mounted to absorb the shock, vibration generated in the downward direction with respect to the tub 11 when driving the washing machine (17) And an absorber 18 formed inside the shock absorbing spring 17 and mounted to absorb shocks and vibrations generated upwardly with respect to the tub 11 due to its extension drive. Preferably, the brackets are provided at four positions of the outer periphery of the front part of the tub 11 and the left and right both sides of the rear side. 12 and 13, and corresponding brackets 15 on the opposing frames 14 on both the left and right sides provided forward and backward along the tub 11 with respect to the brackets 12 and 13, respectively. And a buffer spring 17 and a buffer spring 17 together with the buffer spring 17 on the inner same axis of the buffer spring 17 as a cushioning member therebetween. The shock absorbing spring 17 and the shock absorber 18 are installed in the vertical direction from the upper bracket (12, 13) toward the lower bracket (15, 16), the shock absorbing spring (17) installed on the rear of the tub (11) And the shock absorber 18 are inclined downward from the upper brackets 12 and 13 toward the lower brackets 15 and 16.

At this time, the reference numeral 19, 19A is a detergent (washing oil; solvent) in the detergent container 20 mounted on the frame 14 to the lower side of the tub 11 described above to the drum 10 of the tub 11. It is a detergent circulation pump that is supplied to the first detergent filter 21 and the second detergent filter 22 to be connected to filter the foreign matter by its own filter (not shown) and then supplied to the drum (10).

Hereinafter, a method of using the shock absorber of the drum washing machine according to the present invention will be described.

In the shock absorber of the drum washing machine according to the present invention, the laundry and the washing water are supplied to the drum 10 to wash the laundry, and the detergent (solvent) in the detergent container 20 is supplied to the drum 10 and the detergent container 20 after washing. It is to be noted that since the discharge to the same applies to substantially the same as shown in Figure 1, a detailed description thereof will be omitted.

Thus, as shown in FIGS. 2 and 4, the laundry and the washing water are loaded into the drum 10 and then mounted in the tub 11 due to the driving of the driving means, which is not shown, mounted on the frame 14. As the drum 10 rotates, washing is performed by repeatedly washing, rinsing, and dehydrating strokes.

As a result, the drum 31 rotates as the driving force of the driving motor 32 is transmitted to the rotating shaft 35 of the drum 31 and the shaft fixed pulley 42 through the belt 34 to drive the driving motor 32. do.

Therefore, the laundry is placed at a 120 ° angle inside the drum 31 while the laundry introduced into the drum 31 is rotated according to the rotation of the drum 31 by the driving motor 32. After being raised to a certain height inside the drum 31 by three water flow adjusting devices, the laundry is knocked out by colliding with the drum 31 when the laundry falls.

At this time, the shock absorbing member is coaxial between the outer periphery of the tub 30 and the frame 33 for fixing the tub 30 to absorb and alleviate the shock, vibration and noise generated in the tub 30 during the dehydration process of the laundry. Mounted onto the table.

That is, the above-mentioned shock absorbing member is a shock generated downward against the tub 30 when dewatering between the brackets 36 and 37 formed on the four corners of the frame 33 and the brackets 38 and 39 of the tub 30. The shock absorber 40 is installed to absorb vibration, and the shock absorber is formed inside the shock absorber 40 to absorb shock and vibration generated upwards with respect to the tub 30 due to its extension drive. (41).

On the other hand, the description of the operation of the buffer member (buffer spring 40, shock absorber 41) for absorbing and mitigating shock and vibration generated in the tub 31 when the laundry is dewatered, shown in Figures 2 to 4 Since the same applies to the dry washing machine, the description thereof will be omitted.

As described above, according to a preferred embodiment, the washing machine is driven by mounting the shock absorber and the compression spring coaxially to absorb the shock and vibration in the vertical direction between the tub of the commercial drum washing machine or water washing machine and the frame for holding the same. It is designed to improve durability by completely absorbing and mitigating shock, vibration and noise generated during dehydration.
