Description
Technical Field
The present invention relates to an ultrasonic wave generating unit of a drum washing machine and a drum washing machine having an ultrasonic wave generating function using the same, and more particularly, to an ultrasonic wave generating unit of a drum washing machine, which is installed at a door of a drum washing machine, rotates according to the flow of washing water, and continuously emits ultrasonic waves to laundry to improve the washing efficiency of the drum washing machine, and a drum washing machine having an ultrasonic wave generating function using the same.
Background
A general drum washing machine includes a tub to store wash water, and a drum rotatably disposed in the tub.
The drum is partially immersed in the washing water stored in the tub, and the laundry is thrown into the inside of the drum, and the drum receives the washing water from the tub and rotates together with the laundry inside thereof. The laundry is lifted up and dropped down inside the drum due to the rotation of the drum, and the washing is achieved by the energy generated at this time and the physicochemical action of the laundry and the washing water.
However, the related art drum washing machine has the following problems.
First, in order to obtain appropriate energy required for washing, the drum washing machine needs to limit the rotation speed of the drum to a speed within a specific range, and also has a limit to increase the size of the drum in order to increase energy. Therefore, the drum washing machine cannot improve washing capacity above a certain efficiency. Therefore, in order to obtain appropriate energy, it is necessary to extend the time required for the washing process of the drum washing machine.
Second, when the laundry is large, the washing ability is reduced. The drum washing machine makes the laundry into a mass in the washing process. The drum washing machine has an effect of performing beating washing using energy generated when laundry falls down. In the drum washing machine, when the laundry is agglomerated, energy generated when falling is reduced, thereby reducing washing ability.
In order to solve such problems, a drum washing machine disclosed in korean patent laid-open No. 10-1275204 includes a tub storing washing water, a drum rotatably disposed in the tub, and an ultrasonic wave generating device generating ultrasonic waves to the inside of the drum.
However, in the ultrasonic washing machine according to the above-mentioned related art, the ultrasonic wave generating part is fixed, and thus, when the drum rotates, the laundry rotating together with the drum may be separated from the ultrasonic wave emitting range of the fixed ultrasonic wave generating part, or the ultrasonic wave generating part may be separated from the washing water along with the flow of the washing water, thereby reducing the washing efficiency using the ultrasonic wave.

Detailed Description
Hereinafter, a drum washing machine having an ultrasonic wave generating function according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
A drum washing machine 1 having an ultrasonic wave generating function according to an embodiment of the present invention is shown in fig. 1 to 5.
Referring to fig. 1 to 5, a drum washing machine 1 having an ultrasonic wave generating function of the present invention includes: a body 40 including a case 41 and a door 45; a tub 50 disposed in the body 40 and including a water storage space 51 storing washing water; a drum 60 rotatably disposed inside the tub 50; and an ultrasonic wave generating unit 2 emitting ultrasonic waves to the washing water stored in the tub 50.
The main body 40 includes a case 41 having an opening 42 formed in a front surface thereof, and a door 45 for opening and closing the opening 42.
The cabinet 41 has a hexahedral shape, and an opening 42 is formed at a front surface thereof so that laundry can enter and exit.
The door 45 seals the opening portion 42. The door 45 is closely coupled to the case 41 and fastened to the case 41, and includes a protrusion 46 protruding from the door 45 toward the inside of the tub 50.
The cross-section of the projection 46 is circular. The protrusion 46 seals the opening 42 to prevent the washing water stored in the tub 50 from leaking.
The tub 50 is disposed inside the case 41. The tub 50 includes a water storage space 51 storing washing water.
The drum 60 is cylindrical and is arranged long in the front-rear direction. The drum 60 is rotatably disposed inside the tub 50. A plurality of communication holes 61 are formed on the drum 60, and the drum 60 shares the washing water stored in the tub 50 through the plurality of communication holes 61.
The drum 60 rotates while agitating the laundry and the washing water inside the drum 60. At this time, the drum 60 includes a rotating wing 62 to effectively agitate the laundry and the washing water. The rotary wings 62 extend in the front-rear direction at the inner circumferential surface of the drum 60, and are formed at the same intervals in the rotation direction of the drum 60.
The ultrasonic wave generating unit 2 includes: a housing 10 disposed on the door 45 and forming an inner space; an ultrasonic generator 20 disposed inside the housing 10 to emit ultrasonic waves to the washing water; and a rotation support 30 supporting the housing 10 when the washing water flows by the rotation of the drum 60, such that the housing 10 can be rotated by the flow of the washing water.
The housing 10 is rotatably provided on the protruding portion 46 by the rotation support portion 30.
The housing 10 includes: a rotating body 11 provided on the protruding portion 46; and a body cover 12 covering the rotating body 11 and fixed to the rotating body 11 by bolts 13.
The rotating body 11 has a circular plate shape. The diameter of the rotating body 11 is formed to be not greater than that of the section of the protrusion 46 to prevent the laundry from being caught between the protrusion 46 and the rotating body 11.
An ultrasonic generator 20 is provided inside the body cover 12. The body cover 12 is fixed to the rotating body 11 by bolts 13. A gasket 14 is included between the body cover 12 and the rotating body 11 to prevent wash water from flowing into the inside of the body cover 12. The upper portion of the main body cover 12 is formed to be inclined such that, when the laundry is separated from the inside of the drum 60 to the opening 42, the laundry collides against the main body cover 12 and returns to the inside of the drum 60.
The ultrasonic generator 20 is disposed inside the body cover 12 and is disposed near the lower end at the lower portion of the body cover 12 such that the ultrasonic generator 20 is located below the water surface of the washing water stored in the tub 50. Accordingly, since the ultrasonic generator 20 is located under the water surface of the washing water and emits ultrasonic waves to the inside of the drum 60, the ultrasonic generator 20 can continuously emit ultrasonic waves to the laundry immersed in the washing water.
A power supply 21 may be included inside the housing 10 to supply power to the ultrasonic generator 20.
The rotation support portion 30 includes a main body rotation shaft 31 and a shaft support bearing 32.
The body rotation shaft 31 protrudes from the center of the rotating body 11. The main body rotation shaft 31 is provided to be introduced into a through hole 46a formed in the center of the protruding portion 46 through the shaft support bearing 32 and to be rotatable.
The shaft support bearing 32 is provided to be introduced into the through hole 46 a. A projection projecting in the centripetal direction of the through hole 46a is formed at the rear end of the through hole 46 a. Therefore, the shaft support bearing 32 is prevented from coming off the rear end of the protruding portion 46 by the protrusion protruding in the radial direction of the through hole 46 a.
When the body rotation shaft 31 is introduced into the shaft support bearing 32, the stopper ring 33 is fastened to the body rotation shaft 31. Therefore, the body rotation shaft 31 is prevented from being detached toward the rear end of the shaft support bearing 32.
The housing 10 can be rotated in the left and right directions about the main body rotation shaft 31 by the rotation support part 30.
Fig. 6 to 8 show an operation state of the drum washing machine 1 according to an embodiment of the present invention.
Referring to fig. 6 to 8, when the drum 60 rotates, the washing water flows to the left and right sides by the rotation of the drum 60. At this time, the washing water flows while colliding with the housing 10, and the housing 10 is rotated in synchronization with the flow of the washing water by a frictional force generated by the collision of the washing water with the housing 10.
In a state where the drum 60 is stopped, the washing water is located at a lower portion of the drum 60, and the cabinet 10 is in a stopped state. At this time, the ultrasonic generator 20 is located below the water surface of the washing water.
When the drum 60 rotates in the clockwise direction, the washing water may be inclined toward the left side of the drum 60. At this time, the housing 10 is rotated in a direction in which the washing water flows by friction with the washing water, and the ultrasonic generator 20 is continuously located under the water surface of the washing water inclined to the left side.
In contrast, when the drum 60 rotates in the counterclockwise direction, the washing water may be inclined toward the right side of the drum 60. Likewise, the housing 10 is rotated in a direction in which the washing water flows by friction with the washing water, and the ultrasonic generator 20 is continuously located under the water surface of the washing water inclined to the right side.
In the drum washing machine 1 having the above-described configuration, even if the laundry is inclined to the left or right in the drum 60 while the drum 60 is rotated, the ultrasonic wave generating unit 2 rotates with the flow of the washing water and continuously emits the ultrasonic wave to the laundry, so that the washing efficiency using the ultrasonic wave can be improved.
Further, a drum washing machine 101 according to another embodiment of the present invention is shown in fig. 9 to 10. The constituent elements having the same functions as those in the above drawings are denoted by the same reference numerals, and detailed description thereof is omitted.
Referring to fig. 9 to 10, a drum washing machine 101 according to another embodiment of the present invention has the same configuration as the drum washing machine 1 according to an embodiment of the present invention except for a rotational force increasing part 70 of an ultrasonic wave generating unit 102.
The rotational force increasing part 70 is provided on the outer circumferential surface of the main body cover 12 to be immersed in the washing water stored in the tub 50. When the drum 60 rotates, the washing water flows to the left or right side of the drum 60 according to the rotation direction of the drum 60. At this time, the washing water collides with the rotational force increasing part 70, thereby increasing the rotational force of the casing 10.
The turning force increasing part 70 is constituted by a plurality of turning force increasing blades 71, 72. Of the plurality of rotational force increasing blades 71, 72, the center rotational force increasing blade 71 located at the center is formed to have the same outer shape as the side rotational force increasing blades 72 located at the left and right sides, but to be heavier than the side rotational force increasing blades 72.
The center rotational force increasing blade 71 is provided at a lower end of the housing 10 and protrudes in a centrifugal direction with respect to the center of the housing 10. Both side surfaces of the center rotational force increasing blade 71 in the left and right direction collide with the washing water, thereby increasing the rotational force of the housing 10.
The center rotational force increasing blade 71 may be formed of a material having a density greater than that of the side rotational force increasing blades 72. Further, the central rotational force increasing blade 71 may be formed in a hollow shape and include a weight inside thereof, so that the central rotational force increasing blade 71 is formed to be heavier than the side rotational force increasing blades 72.
The density of the central rotational force increasing vane 71 is greater than that of the side rotational force increasing vane 72 and the washing water. When the external force disappears after the rotation of the housing 10, the center rotational force increasing blade 71 is rapidly returned from the original position, i.e., the center of the housing 10, in the vertically downward direction.
The pair of side rotational force increasing blades 72 are spaced apart from the center rotational force increasing blade 71 at the same interval at both sides of the center rotational force increasing blade 71.
Although the side rotational force increasing blades 72 according to another embodiment of the present invention protrude in a centrifugal direction with respect to the center of the housing 10, the side rotational force increasing blades 72 may protrude in a horizontal direction with the center rotational force increasing blade 71, differently from this.
The pair of side rotational force increasing blades 72 may be formed in a hollow shape to provide buoyancy to the case 10. Accordingly, the housing 10 may be rotated not only by collision with the washing water but also by buoyancy of the pair of side rotational force increasing blades 72.
Although the rotational force increasing part 70 according to another embodiment of the present invention is composed of the three rotational force increasing blades 71, 72, the rotational force required to rotate the housing may be varied according to the weight of the housing, the storage amount of the washing water according to the size of the drum, and the like. Therefore, the number of the rotational force increasing blades may be varied according to a required rotational force.
Further, the rotational force increasing part 70 of the ultrasonic wave generating unit 102 according to another embodiment of the present invention may be constituted by only one center rotational force increasing blade 71, omitting the pair of side rotational force increasing blades 72.
Fig. 11 to 13 show operation states of the drum washing machine 101 according to another embodiment of the present invention.
Referring to fig. 11 to 13, in a state where the drum 60 is stopped, the washing water is located at a lower portion of the drum 60, and the cabinet 10 is in a stopped state. At this time, the ultrasonic generator 20 is located below the water surface of the washing water.
When the drum 60 rotates in the clockwise direction, the washing water may be inclined toward the right side of the drum 60. At this time, the rotational force increasing part 70 collides with the washing water, thereby increasing the rotational force of the housing 10 rotating in the direction in which the washing water flows. The central rotational force increases the load of the blade 71, so that the housing 10 does not rotate more than a certain angle, and the ultrasonic generator 20 is continuously located below the water surface of the washing water inclined to the right side.
In contrast, when the drum 60 rotates in the counterclockwise direction, the washing water may be inclined toward the left side of the drum 60. Similarly, the rotational force increasing part 70 collides with the washing water to increase the rotational force of the housing 10 rotating in the direction in which the washing water flows, and the central rotational force increases the load of the blade 71, so that the housing 10 does not rotate more than a certain angle. The ultrasonic generator 20 is continuously located below the water surface of the washing water inclined to the left side.
The drum washing machine 101 having the above-described configuration can increase the rotational force of the casing 10 rotated by the flow of the washing water, and thus can increase the rotational range of the casing 10 even if the flow of the washing water is small, thereby expanding the ultrasonic wave emitting range of the ultrasonic wave generator 20.
As such, in the drum washing machine 1 according to the present invention, even if the laundry is inclined to the left or right side inside the drum 60 while the drum 60 is rotated, since the ultrasonic wave generating unit 2 rotates along with the flow of the washing water and continuously emits the ultrasonic wave to the laundry, the washing efficiency using the ultrasonic wave can be improved. Also, the ultrasonic generator 20 may continuously emit ultrasonic waves toward the inside of the drum 60 under the water surface of the washing water, thereby improving the washing efficiency of the drum washing machine 1.
While the invention has been described with reference to an embodiment, this is by way of example only, and it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted. Accordingly, the true scope of the invention should be determined only by the following claims.
