Description

Noise filter fixing structure of the drum washing machine {The noise filter mounting of a drum washer}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a noise filter fixing structure of a drum washing machine, and more particularly, to a noise filter of a drum washing machine which can prevent the noise filter from being separated by vibration generated when the drum washing machine is operated.

In general, the drum washing machine washes by using the friction between the drum and the laundry rotated by the driving force of the motor while detergent, washing water and laundry are put in the drum installed horizontally. There is almost no damage to the laundry and the laundry does not get tangled with each other. Knocking and rubbing has a washing effect.

1 is a perspective view showing a general drum washing machine, Figure 2 is a perspective view showing a noise filter fixing structure of the drum washing machine according to the prior art.

In general, the drum washing machine is a tub (not shown) horizontally installed inside the cabinet body 2 with the front open as shown in FIG. 1, and rotatably installed inside the tub (not shown) to wash laundry. And a motor (not shown) installed at the rear of the tub 4 and connected to the drum 4 and the rotating shaft (not shown) to rotate the drum 4.

In addition, a cabinet cover 3 having an input hole h is installed at a front surface of the cabinet body 2 so that laundry can enter and exit the drum 4, and the drum 4 is installed at the input hole h. In order to prevent the laundry from being separated from the door 8 is provided to be opened and closed.

On the other hand, a control panel 10 for controlling the operation of the drum washing machine and a control part (not shown) is installed on the front upper side of the cabinet body 2, the control part (not shown) is the water supply valve (Not shown), a drain valve (not shown), a motor (not shown), and the like are connected to each other by an electric wire.

Therefore, since a control signal is transmitted along a wire connecting the above devices, an unwanted signal is generated or attenuated by a control signal generated as the drum washing machine operates due to external noise in the middle of the wire. In order to achieve this, the noise filter 10 is installed in various places.

In particular, as illustrated in FIG. 2, the noise filter 10 embedded in the filter case 12 is fixed inside the rear side of the cabinet body 2, and the first and second fixed ends are respectively disposed on upper and lower ends of the filter case 12. 12a and 12b are formed, and the first and second fixed ends 12a and 12b are slidably inserted into the first and second holders 14a and 14b in which the rear surface of the cabinet body 2 is firmly formed inward. .

Here, the first holder 14a is formed such that one side and the lower side are opened, and the second holder 14b is formed so that one side and the upper side are opened so that a part of the first fixing end 12a and the second fixing portion 14a are opened. The stage 12b is slidably inserted into the first and second holders 14a and 14b, respectively, and the first fixed end 12a is fixed to the cabinet body 2 by screws S.

However, in the conventional noise filter fixing structure of the drum washing machine, the first and second fixing ends 12a and 12b of the filter case 12 having the noise filter are inserted into the first and second holders 14a14b, Since the first fixing ends 12a and 12b are fixed to the cabinet body 2 with screws S, when vibration occurs during the operation of the drum washing machine, the second fixing ends 12b rotate about the screws S. Therefore, there is a problem that noise is generated when the filter case 12 is separated from the second holder 14b.

The present invention has been made to solve the above-mentioned problems of the prior art, and even if the vibration is generated when the drum washing machine operation of the noise filter fixing structure of the drum washing machine that can be fixed so that the filter case with a built-in noise filter is not separated from the cabinet. The purpose is to provide.

In the noise filter fixing structure of the drum washing machine according to the present invention for solving the above problems, the first and second fixed ends are formed at both ends of the filter case in which the noise filter is embedded, and the first fixed end is screwed to the cabinet. In the noise filter fixing structure of the drum washing machine is fixed, the second fixing end is inserted into the holder formed in the cabinet, the holder is the second fixing end so that the second fixing end is not separated from the holder during vibration One side is characterized in that the groove is open so that it can be fitted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a perspective view illustrating a noise filter fixing structure of the drum washing machine according to the present invention, and FIG. 4 is a perspective view illustrating a state in which the noise filter of the drum washing machine is fixed.

The noise filter fixing structure of the drum washing machine according to the present invention has a noise filter to prevent unwanted signals from being generated or attenuated by the external noise in the control signals transmitted along a plurality of wires as shown in FIG. 3. A plurality of 60 are installed inside the cabinet body 52, in particular, the noise filter 60 installed on the motor (not shown) side is embedded inside the filter case 62 so as not to be separated by vibration during operation of the drum washing machine. The cabinet body 52 is fixed to the rear.

Here, the filter case 62 has first and second fixed ends 62a and 62b formed at upper and lower ends, respectively, and the first and second fixed ends 62a of the filter case 62 are formed at the rear of the cabinet body 52. Positioning portion 64 and the holder 66 is firmly formed so as to protrude in the inward direction of the cabinet body 52 at a position corresponding to .62b.

In particular, the positioning unit 64 is a rectangular groove having a lower side and one side open so that one edge of the upper end of the first fixing end 62a can be inserted, and the holder 66 has the second fixing end ( 62b) is a rectangular groove open only on the upper side to be inserted.

In addition, the boss having a screw thread formed inside the first fixing end 62a and the filter case 62 so that the filter case 62 may be fixed to the cabinet body 52 by a screw S. (B) is formed.

Looking at the noise filter fixing order and operation of the drum washing machine according to the present invention configured as described above are as follows.

First, as shown in FIG. 4, the second fixing end 62b of the filter case 62 is inserted into a holder 66 formed inside the rear side of the cabinet body 52 and the first fixing end of the filter case 62. One end portion 62a is slidably inserted into the positioning portion 64 formed inside the rear surface of the cabinet body 52 while the upper one side edge portion is rotated about the second fixing end 62b.

In addition, the boss B formed on the first fixing end 62a and the filter case 62 is fastened by the cabinet body 52 and the screw S.

Thereafter, a noise filter 60 having a wire wound inside the filter case 62 is embedded.

Therefore, even if the drum washing machine is operated to generate vibration in the up, down, left and right directions, the filter case 62 has the second fixing end 62b inserted into the holder 66, and the first fixing end 62a is the cabinet body ( Since it is fixed by the screw S to 52, it does not separate from the cabinet main body 52. FIG.

The noise filter fixing structure of the drum washing machine according to the present invention configured as described above has a first and second fixing ends formed at both ends of the filter case in which the noise filter is built, and a holder having one side and a positioning portion formed at the rear of the cabinet. Is fixed to the holder, and the second fixing end is fitted to the holder, and the first fixing end is slidably inserted into the positioning part so as to be fixed with a screw, so that the filter case is not separated from the cabinet even if vibration is generated when the drum washing machine is operated. In addition to fixing to prevent the noise is generated when the filter case is removed there is an advantage.
