A washing machine, which is a device for washing clothes with mechanical force, is classified into a cylinder type, an agitator type, and a pulsator type washing machine depending on its structure. In addition, it is divided into a household washing machine mainly used for washing a small amount of clothes within 20 kg at home, and an industrial washing machine used for washing clothes in large quantities in a laundry, a hotel, a hospital and the like.

Since the industrial washing machine is bulky and has a high height, the agitated or waved washing machine provided at the upper side of the laundry loading port is not suitable for industrial washing machine because it is not easy to put in and take out laundry, and drum type washing machine is usually applied to industrial washing machine do. FIG. 1 is a side view showing an industrial washing machine according to a conventional example. Referring to FIG. 1, a conventional industrial washing machine 4 includes a base 5 and a hinge 6 And a washing machine body (7) slidably coupled. The washing machine main body 7 includes a tub 9 as a washing tub and a drum (not shown) disposed in the tub 9 and rotating at a high speed. The laundry is charged into the drum 9 , And a door (8) is provided on a front surface of the drum so that laundry can be taken out from the drum. A water supply hose 3 connected to the water pipe 1 is connected to the back surface of the washer main body 7 so that water can be supplied to the tub 9.

The washer main body 7 can be inclined around the hinge 6 by the power of the motor. During the washing of the laundry, four corners of the bottom of the washing machine main body 7 are supported on the base 5 as shown by two-dot chain lines, and the washing machine main body 7 is erected straight. However, when the washing is finished, the door 8 is opened and the washing machine body 7 rotates around the hinge 6 by a certain angle so that the rear surface of the washing machine body 7 can be heard as shown by the solid line. Thus, the washing machine main body 7 is inclined so that the laundry in the drum is naturally discharged to the outside of the washing machine main body 7 by gravity or is easily removed by the operator.

However, in the conventional industrial washing machine 4, the water supply hose 3 connected to the back surface of the washing machine main body 7 has to be sufficiently long in consideration of the rotation of the washing machine main body 7. As a result, the water supply hose 3 may be attracted to the floor and contaminated or damaged as shown by the two-dotted chain line, and the operator may inadvertently step on or hit the water supply hose 3, thereby hindering the laundry operation. On the other hand, the structure of rotating the washing machine body 7 directly with the power of the rotating shaft of the motor also has a problem that the power of the motor is insufficient and it is difficult to tilt the washing machine body 7 at a sufficient angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a tiltable washing machine according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The terminology used herein is a term used to properly express the preferred embodiment of the present invention, which may vary depending on the intention of the user or operator or the custom in the field to which the present invention belongs. Therefore, the definitions of these terms should be based on the contents throughout this specification.

FIG. 2 is a perspective view illustrating the tiltable washing machine according to the embodiment of the present invention, and FIG. 3 is a side view illustrating the tiltable washing machine according to the embodiment of the present invention. 2 and 3, the tilable washing machine 10 according to the embodiment of the present invention includes a washing machine body 20, a base 11, an actuator, a water supply passage, Respectively. The washing machine main body 20 is a so-called drum type washing machine configured to put laundry into the washing machine body 20 through a front door 28 or to take laundry out of the washing machine body 20, A tub 30, and a drum 32. The drum 30 is a drum.

The main body housing 21 has a rectangular parallelepiped shape and includes a plurality of beams 22 as a skeleton and a panel 23 as an outer shell and a front door 28 that can be opened and closed is provided on the front surface . However, the structure and the shape of the housing 21 are not limited thereto. For example, the housing 22 may be composed of only the beam 22 without the panel 23, or vice versa. A tub 30, which is a washing tub, is disposed inside the main body housing 21, and a drum 32 is rotatably disposed within the tub 30. When the front door 28 is opened, the laundry can be introduced into the drum 32, and the laundry accumulated in the drum 32 can be taken out of the main housing 21.

The base 11 supports the washing machine main body 20 and the lower end of the front surface of the main body housing 21 is connected to a front floor 13 of the base 11 by a hinge 17. [ And is rotatably coupled. The actuator rotates the washing machine body 20 about the hinge 17 and includes a hydraulic cylinder 35. The hydraulic cylinder 35 has a cylinder-shaped body 36 and a rod 39 whose lower side is fitted to the body 36. The lower end 37 of the body 36 is pivotally coupled to the back floor of the base 11 and the upper end 40 of the rod 39 is pivotally rotatably coupled to the back surface of the body housing 21. [ . Although only one hydraulic cylinder 35 is shown in FIG. 3, a plurality of hydraulic cylinders may be provided. Further, a hydraulic cylinder may be provided on the left and right sides of the main body housing, not on the back surface of the main body housing.

When hydraulic pressure is applied to the inside of the body 36 by a hydraulic operation motor (not shown), the rod 39 moves in the direction to be inserted into the body 36 or vice versa in the direction in which the rod 39 protrudes from the body 36 . 3, the four corners of the bottom of the main body housing 21 are connected to the bottom 12 of the base 11, as shown by the two-dot chain line in FIG. 3, . At this time, most of the rod 39 of the hydraulic cylinder 35 is inserted into the body 36 and only the upper end portion 40 is protruded out of the body 36.

When the washing operation is completed in the washing machine main body 20 and the hydraulic operation motor of the actuator is operated, the rod 39 moves in the direction of protruding from the body 36 to move the rod 39 from the lower end 37 of the body 36, The length to the upper end portion 40 is elongated. When the washing machine main body 20 is rotated about the hinge 17 by a predetermined angle TA due to the stretching force of the hydraulic cylinder 35, the lower end of the back surface of the main housing 21 contacts the bottom 12 of the base 11, And the washer main body 20 is inclined to be bent forward. When the washing machine body 20 is tilted forward, the laundry in the drum 32 is moved toward the front door 28. Thus, the laundry in the drum 32 is opened by opening the front door 28, ).

The washing machine main body 20 is not tilted so that the lower end of the back surface of the main body housing 21 contacts the bottom 12 of the base 11 in order to tilt the washing machine main body 20, The largest force is required in the supported state. Therefore, at this time, the rod 39 of the hydraulic cylinder 35 is installed so as to be orthogonal to the bottom 12 of the base 11, that is, the rod 39 is extended in parallel with the Z axis, The direction of the extension force of the cylinder 35 and the direction of gravity are opposite to each other so that the extension of the hydraulic cylinder 35 is used to rotate the washing machine body 20 around the hinge 17 without waste. 3, when the washing machine main body 20 rotates about the hinge 17 and the lower end of the back surface of the main body housing 21 is separated from the bottom 12 of the base 11, The rod 39 of the base 35 is inclined with respect to the bottom 12 of the base 11.

The use of the hydraulic cylinder 35 without using the power of the electric motor having the rotary shaft for tilting the washing machine main body 20 makes it possible to reduce the cost since it is not necessary to apply a large- The reliability of the rotation operation around the hinge 17 is improved and the washing machine body 20 can be stably held in a tilted posture. The rotatable angle TA of the washer main body 20 is determined according to the stroke range of the rod 39. [ Since the load that can be supported while the rod 39 of the hydraulic cylinder 35 is stopped at a position within the stroke range is larger than that of the rotary shaft of the electric motor, 20 can be tilted at a relatively large angle TA and stably maintained in a tilted posture.

The water supply unit supplies water required for washing from the water pipe 1 to the tub 30 of the washer main body 20. The water supply passage is disposed at a position that does not interfere with the rotation of the washer main body 20 and is fixed to the base 11. The water supply unit includes a water supply flow path 48 for guiding water from the water pipe 1 to a rear side of the washing machine body 20 and a water supply path 48 fixed to the base 11 and not interfering with rotation of the washing machine body 20 And a second flow path 53 connected to the end of the first flow path 51 and leading water to the washing machine main body 20. The first flow path 51, The first flow path 51 is a pipe made of a non-bending material such as metal or plastic and the second flow path 53 is a flow path such as a hose. A plurality of the water supply flow path 48, the first flow path 51, and the second flow path 53 may be provided.

The first flow path 51 maintains a height lower than the height of the end of the second flow path 53 connected to the washing machine main body 20 and specifically to the tub 30 and the left or right corner of the base 11, As shown in Fig. The base 11 has a side wall 18 protruding upward from the left and right corners and a first flow path 51 is fixedly supported on the side wall 18 so that the first flow path 51 is connected to the base 11 parallel to the X-axis while being spaced apart from the side floors 14 by a predetermined height. 2, the first flow path 51 extends parallel to the X axis, that is, in the front-rear direction, between the side wall 18 of the base 11 and the side surface of the main housing 21. [

One end of the second flow path (53) is connected to the front end of the first flow path (51), and the other end is connected to the tub (30). An opening 23a is formed in the side surface of the main body housing 21 and the second flow path is connected to the tub 30 through the side surface of the main body housing 21 through the opening 23a. The opening 23a is formed closer to the front than the rear surface of the main housing 21 so that the opening 23a is close to the hinge 17. Even if the washing machine main body 20 rotates about the hinge 17, (23a) and the length of the second flow path (53) can be shortened so as not to touch the floor of the workplace. The first flow path 51 and the second flow path 53 can be disposed in the region of the base 11 so that the second flow path 53 made of a soft material is attracted to the floor and is not contaminated or damaged. There is no fear that the second flow path 53 will be stepped on or struck, thereby hindering the laundry operation.

An impact is applied to the tub 30 and the drum 32 when the washing machine main body 20 rotates about the hinge 17 or when washing is performed while the drum 32 rotates. The buffer unit mitigates the impact applied to the tub 30 and the drum 32 in the process described above. The shock absorbing unit has a structure in which the upper end is connected to the beam 22 or the panel 23 at the upper end of the main body housing 21 and the lower end thereof is fixed to the outer circumferential wall of the tub 30 or a frame And a plurality of springs (42) connected and supported by the spring (42). The lower end of the shock absorber unit is connected to the beam 22 or the panel 23 at the lower end of the main body housing 21 and the upper end of the shock absorber is fixed to the outer circumferential wall of the tub 30, And a plurality of shock absorbers 45 connected to and supported by a shaft (not shown).

Although not shown in detail, the shock absorber 45 has a cylinder filled with oil and a piston movable in the longitudinal direction of the cylinder inside the cylinder. When the piston is pressed by the external impact and moves in one direction inside the cylinder, the oil in the cylinder moves through the orifice formed in the piston to the other space in one side space, .

FIG. 4 is a perspective view illustrating a tilting-type washing machine according to another embodiment of the present invention, and FIG. 5 is a side view illustrating the tilting-type washing machine of FIG. The same reference numerals are given to the same components as those of Figs. 2 and 3 in Fig. 4 and Fig. 4 and 5, the tilable washing machine 10 according to the embodiment of the present invention includes a washing machine body 20, a base 11, an actuator, a water supply passage, Respectively. The washing machine main body 20 is a so-called drum type washing machine configured to put laundry into the washing machine body 20 through a front door 28 or to take laundry out of the washing machine body 20, A tub 30, and a drum 32. The drum 30 is a drum.

The main body housing 21 has a rectangular parallelepiped shape and includes a plurality of beams 22 as a skeleton and a panel 23 as an outer shell and a front door 28 that can be opened and closed is provided on the front surface . However, the structure and the shape of the housing 21 are not limited thereto. For example, the housing 22 may be composed of only the beam 22 without the panel 23, or vice versa. A tub 30, which is a washing tub, is disposed inside the main body housing 21, and a drum 32 is rotatably disposed within the tub 30. When the front door 28 is opened, the laundry can be introduced into the drum 32 and the laundry accumulated in the drum 32 can be rotated and taken out of the main housing 21.

The base 11 supports the washing machine main body 20 and the lower end of the front surface of the main body housing 21 is connected to a front floor 13 of the base 11 by a hinge 17. [ And is rotatably coupled. The actuator rotates the washing machine body 20 about the hinge 17 and includes a hydraulic cylinder 35. The hydraulic cylinder 35 has a cylinder-shaped body 36 and a rod 39 whose lower side is fitted to the body 36. The lower end 37 of the body 36 is pivotally coupled to the side wall 14 of the base 11 and the upper end 40 of the rod 39 is pivotally connected to the side of the body housing 21. [ And is rotatably coupled. Although only one hydraulic cylinder 35 is shown in Figs. 4 and 5, a hydraulic cylinder identical to that shown on the opposite side not shown is provided.

When hydraulic pressure is applied to the inside of the body 36 by a hydraulic operation motor (not shown), the rod 39 moves in the direction to be inserted into the body 36 or vice versa in the direction in which the rod 39 protrudes from the body 36 . 3, the four corners of the bottom of the main body housing 21 are connected to the bottom 12 of the base 11, as shown by the two-dot chain line in FIG. 3, . At this time, most of the rod 39 of the hydraulic cylinder 35 is inserted into the body 36 and only the upper end portion 40 protrudes out of the body 36.

When the washing operation is completed in the washing machine main body 20 and the hydraulic operation motor of the actuator is operated, the rod 39 moves in the direction of protruding from the body 36 to move the rod 39 from the lower end 37 of the body 36, The length to the upper end portion 40 is elongated. When the washing machine main body 20 is rotated about the hinge 17 by a predetermined angle TA due to the stretching force of the hydraulic cylinder 35, the lower end of the back surface of the main housing 21 contacts the bottom 12 of the base 11, And the washer main body 20 is inclined to be bent forward. When the washing machine body 20 is tilted forward, the laundry in the drum 32 is moved toward the front door 28, so that the front door 28 is opened so that laundry in the drum 32 can be easily removed from the washing machine main body 20 .

The washing machine main body 20 is not tilted so that the lower end of the back surface of the main body housing 21 contacts the bottom 12 of the base 11 in order to tilt the washing machine main body 20, The largest force is required in the supported state. Therefore, at this time, the rod 39 of the hydraulic cylinder 35 is installed so as to be orthogonal to the bottom 12 of the base 11, that is, the rod 39 is extended in parallel with the Z axis, The direction of the extension force of the cylinder 35 and the direction of gravity are opposite to each other so that the extension of the hydraulic cylinder 35 is used to rotate the washing machine body 20 around the hinge 17 without waste. 3, when the washing machine main body 20 rotates about the hinge 17 and the lower end of the back surface of the main body housing 21 is separated from the bottom 12 of the base 11, The rod of the rod 35 is inclined with respect to the bottom 12 of the base 11.

The use of the hydraulic cylinder 35 without using the power of the electric motor having the rotary shaft for tilting the washing machine main body 20 makes it possible to reduce the cost since it is not necessary to apply a large- The reliability of the rotation operation around the hinge 17 is improved and the washing machine body 20 can be stably held in a tilted posture. The rotatable angle TA of the washer main body 20 is determined according to the stroke range of the rod 39. [ However, since the load that can be supported while the rod 39 of the hydraulic cylinder 35 is stopped in a position within the stroke range is larger than that of the rotating shaft of the electric motor, when the laundry is filled in the tub 30, The main body 20 can be tilted at a relatively large angle TA and stably maintained in a tilted posture.

The water supply unit supplies water required for washing from the water pipe (1) to the tub (30). The water supply unit includes a hard channel 48 for guiding water from the water pipe 1 to a rear side of the washing machine body 20 and a water channel 48 connected to the end of the hard channel 48, (Soft) flow path 51 for guiding the fluid. The flexible channel 51 can be connected to the rear side of the main body housing 21 or the side or upper side closer to the back side than the front side of the main body housing 21 to guide the water. The hard channel 48 is a metal or plastic pipe and the soft channel 51 may be a flexible hose.

The base 11 further includes a support 15 protruding upward from the rear of the washer main body 20 in parallel with the Z axis and the end of the hard channel 48 is supported at the upper end of the support 15. Specifically, the hard channel 48 has a faucet 49 for opening and closing the flow of water at its end, and the faucet 49 is connected to a fixing (not shown) And a soft flow path 51 is connected to the end of the water tap (49).

The end of the hard channel 48 extends to the rear of the main body 20 of the washing machine body 20 as close as possible to the main body 20 of the washing machine 20 without interfering with the rotation of the washing machine main body 20, The length of the soft flow path 51 can be shortened so as not to touch the floor of the workplace. Accordingly, there is no fear that the soft flow path 51 will be pulled to the floor so as not to be contaminated or damaged, and that the soft flow path 51 will be stepped on or hit by the operator inadvertently, thereby hindering the laundry operation.

An impact is applied to the tub 30 and the drum 32 when the washing machine main body 20 rotates about the hinge 17 or when washing is performed while the drum 32 rotates. The buffer unit mitigates the impact applied to the tub 30 and the drum 32 in the process described above.
