Description

Washing cover and washing processing equipment with same

Technical Field

The invention relates to a washing cover and a washing processing device with the same.

Background

The laundry treating apparatus may be defined as an apparatus that forcibly rotates wash water and laundry to separate foreign substances attached to the laundry using a surfactant action of a detergent.

In particular, a washing machine, which is one of laundry treating apparatuses, may be classified into a front loading type washing machine and a top loading type washing machine according to a position of a laundry input port. As a front loading type washing machine, a so-called drum washing machine is known, and a door for opening and closing a laundry input port is mounted on a front surface of a washing machine main body. On the other hand, in the top loading type washing machine, a door for opening and closing the laundry loading port is mounted on the top surface of the washing machine main body.

Specifically, the top loading type washing machine includes: the washing machine includes a tub storing laundry, a drum rotatably installed in the tub, and a pulsator installed at a bottom of the drum to forcibly flow wash water and the laundry. In the case of the top loading type washing machine, when the drum and the pulsator are integrally rotated, the washing water filled in the tub ascends in a spiral shape along the vertical wall surface of the tub according to a centrifugal force and then falls to the bottom of the drum.

Specifically, a member called a balancing ring is installed at an upper end of the drum, and a predetermined amount of brine is filled in the inside of the balancing ring. When the drum rotates, the brine inside the balancing ring moves in a direction opposite to the direction in which the drum is inclined, thereby adjusting the balance of the drum. The structure and function of the gimbal is described in detail in prior art 1 below.

In addition, the washing water spirally ascends along the space between the tub and the drum moves toward the center of the drum along the bottom of the tub cover installed at the upper end of the tub and then falls to the bottom of the drum. At this time, foreign substances penetrating into the laundry are separated by collision of the falling washing water with the laundry. The structure and function of the outer tub cover are described in detail in prior art 2 below.

As disclosed in the related art 2, although there is an advantage in that a so-called waterfall flow formed by the outer tub cover collides with laundry to improve a washing effect, there are following disadvantages.

First, in the washing process using the waterfall flow, a large amount of lint is separated from the laundry, and the generated lint cannot be properly filtered, thereby causing the lint to adhere to the laundry and be dried together.

Second, when the washing water having a strong water flow continuously collides with the laundry, damage of the laundry may be caused.

Third, in case of bulky laundry such as bedding, the laundry may be damaged due to friction with the tub cover during the dehydration process due to floating in water.

Fourth, when the waterfall flow is applied to the laundry having a large volume, a portion of the washing water collided with the laundry may be splashed between the tub and the cabinet accommodating the tub, and thus, a water leakage phenomenon may occur at the bottom of the washing machine.

Disclosure of Invention

Problems to be solved by the invention

The present invention has been made to solve the above-described problems.

Technical scheme for solving problems

In order to achieve the above object, a laundry cover according to an embodiment of the present invention includes: a frame having a plurality of openings; and a screen installed on the frame to shield the plurality of openings, and having a plurality of fine pores to filter foreign substances contained in the washing water, wherein an outer edge of the frame is formed higher than a central portion of the frame.

In addition, the laundry treating apparatus according to an embodiment of the present invention may include: an outer tub filled with washing water; a drum accommodated in the inside of the tub and accommodating laundry; a balance ring which is combined with the upper end of the roller and is provided with a feeding opening at the inner side; and a laundry cover according to an embodiment of the present invention, which is put into the inside of the drum to be placed above the laundry.

Effects of the invention

When washing is performed in a state where the laundry cover of the above-described structure is placed above the laundry, the following effects can be obtained.

First, the washing water moving toward the bottom surface of the tub cover after rising along the wall surface of the tub falls to the laundry cover, so that lint contained in the washing water is filtered by the laundry cover. As a result, there is an advantage that the washing can be completed with the lint attached to the laundry, to be minimized.

Secondly, as the falling wash water collides with the laundry cover, the pressure is dispersed, and thus there is an advantage in that damage of the laundry caused by direct collision with the laundry can be minimized.

Third, in the process of washing the laundry having a large volume, the phenomenon that the laundry rises or swells above the bottom surface of the balance ring is prevented by using the laundry cover placed above the laundry, thereby having an advantage of minimizing the splashing phenomenon of the washing water when the waterfall flow is applied to the laundry.

Fourthly, the laundry cover prevents the laundry with a large volume from directly contacting the balance ring and the outer tub cover, thereby having an advantage of minimizing the possibility of damage of the laundry.

Detailed Description

Hereinafter, a laundry cover and a laundry treating apparatus having the same according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, a top loading type washing machine will be exemplified as the laundry treating apparatus according to the embodiment of the present invention, and will be described.

Specifically, the laundry treating apparatus 10 according to the embodiment of the present invention forms an external appearance by a cabinet (not shown) and a top cover (not shown) rotatably provided at a top surface of the cabinet. In addition, inside the cabinet, the outer tub 11 is supported by a plurality of support members.

More specifically, the tub 11 includes a drum 12 formed with a plurality of holes therein, and a pulsator 15 for forcibly flowing washing water is provided at a bottom of the drum 12. In addition, a washing motor (not shown) is provided at a lower side of the pulsator 15, and a rotation shaft of the washing motor is connected to the pulsator. In addition, the pulsator and the drum are rotated together in a washing mode using a clutch member (not shown) provided at one side of the washing motor, and only the drum is allowed to rotate in a dehydrating mode.

In addition, a balancing ring 14 is provided at an upper end of the drum 12 to perform a function of adjusting the balance of the drum 12 when the drum 12 rotates. A hollow portion, which may be divided into a plurality of spaces by partition walls, is formed inside the balance ring 14. In addition, in the hollow portion, saline may be filled.

In addition, an outer tub cover 13 is installed at an upper end of the outer tub 11 to guide the washing water, which is raised by the rotation of the pulsator 15 and the drum 12 during the washing process, to flow toward the center of the drum.

In addition, inside the drum 12, a laundry cover 20 according to an embodiment of the present invention may be accommodated inside the drum 12. The outer diameter of the laundry cover 20 may be formed to be smaller than the inner diameter of the drum 12 and larger than the inner diameter of the balancing ring 14. Therefore, when the laundry cover 20 is placed above the drum 12 after the laundry is put therein, even if the laundry absorbs the washing water and the volume is increased, the laundry cover 20 and the laundry can be prevented from being separated to the outside of the balancing ring 14.

As shown by arrows in the drawing, the washing water spirally flows along the inner circumferential surface of the outer tub 11 by a centrifugal force and ascends during the washing. In addition, the rising washing water is guided to a space between the balancing ring 14 and the outer tub cover 13, and is guided toward the center of the drum 12 along the bottom surface of the outer tub cover 13. In addition, the washing water directed toward the center of the drum 12 drops to the bottom of the drum 12 due to gravity.

Specifically, as disclosed in the related art 2, at the bottom surface of the outer tub cover 13, a plurality of washing water guide vanes for guiding the washing water to flow in a spiral shape may be formed, and a detailed description thereof will be omitted.

Fig. 2 is a perspective view of a laundry cover according to an embodiment of the present invention, and fig. 3 is a cross-sectional view taken along line 3-3 of fig. 2.

Referring to fig. 2 and 3, the laundry cover 20 according to an embodiment of the present invention may include a frame 21 and a screen 22, the frame 21 being formed in a circular or polygonal shape and having a plurality of openings formed inside thereof, the screen 22 being integrally combined with the frame 21 to shield the openings.

Specifically, the screen 22 includes a filter net or a filter having fine pores to filter out foreign substances including lint contained in the washing water. The mesh 22 may be made of fabric (fabric) that can be restored to its original state after being deformed.

In addition, the frame 21 may be designed in a dish shape in which the top surface edge of the laundry cover 20 is higher than the bottom surface. Thereby, not only an effect of pressing down the laundry may be obtained, but also a phenomenon that the foreign matter collected to the mesh 22 by the washing water falling to the top surface of the mesh 22 is separated from the mesh 22 and re-flows to the laundry side may be prevented.

More specifically, the frame 21 may include: an outer frame 211 formed at the outermost side, an inner frame 213 formed at the innermost side, one or more intermediate frames 212 formed between the outer frame 211 and the inner frame 213, and a plurality of connection frames 214 connecting the plurality of frames. The plurality of connection frames 214 extend in a radial shape from the center of the laundry cover 20, and sequentially connect the inner frame 213, the middle frame 212, and the outer frame 214.

In addition, the width of the middle frame 212 may be formed to be different from the width of the outer frame 211, but is not limited thereto. In addition, the outer frame 211, the intermediate frame 212, and the inner frame 213 may be formed in a circular shape as shown in the drawing, or may be formed in a polygonal shape.

In addition, the thickness of the connection frame portion connecting the inner frame 213 and the middle frame 212 may be formed to be different from the width of the connection frame portion connecting the middle frame 212 and the outer frame 211, but is not limited thereto.

In addition, a connection frame portion (which may be defined as a first connection portion) connecting the outer frame 211 and the middle frame 212 may be formed to be inclined lower as closer to the middle frame side. In addition, a connection frame portion (which may be defined as a second connection portion) connecting the middle frame 212 and the inner frame 213 may be horizontally formed, and may also be obliquely formed to be lower as approaching the inner frame 213 side.

In addition, a central opening 201 may be formed inside the inner frame 213. In addition, the inner frame may be formed in a truncated cone shape (truncated cone) or a cylindrical shape having a width that becomes narrower toward the upper side. That is, the inner edge of the inner frame 213 may be formed higher than the outer edge.

In this way, since the outer edge of the frame 21 is formed higher than the center of the frame 21, it is possible to prevent the foreign matter filtered by the mesh 22 from flowing to the outside of the laundry cover 20.

In addition, the inner frame 213 is formed such that an inner edge is higher than an outer edge, thereby minimizing lint caught on the mesh 22 from flowing into the laundry side again through the central opening 201 during the washing process.

In addition, one or more cross bars 23 are formed at the central opening 201 of the inner frame 213 so that a user can grip the cross bars 23 to move the laundry cover 20.

As shown in fig. 1, the outer diameter of the laundry cover 20 may be formed to be greater than the inner diameter of the balancing ring 14 and less than the inner diameter of the drum 12. Due to this structural feature, in order to put the laundry cover 20 inside the drum 12, it is preferable that the laundry cover 20 is made of a material capable of being bent.

For example, the frame 21 is preferably made of a plastic material having flexibility so that the frame is easily bent by an external force and then returns to an original state. Furthermore, the mesh 22 is also preferably made of a material that is restored to its original shape when the external force is removed after the shape is deformed.

In addition, the cross bar 23 may be configured such that both ends of the cross bar are connected to the edges of the central opening 201 after passing through the center of the central opening 201. The cross bar 23 may be arranged in a straight line or in a cross shape as shown in the figure, but it is clear that other shapes may be provided.

Referring to fig. 4, the laundry cover 20 according to the embodiment of the present invention is the same as the laundry cover according to the previous embodiment, however, the inner structure of the inner frame 213 is a slightly changed structure.

Specifically, instead of the cross bar 23 provided at the center opening 201 formed inside the inner frame 213, an arc-shaped lid handle 24 may be provided. In addition, the screen 22 is installed at the central opening 201, so that the lint caught on the top surface of the laundry cover 20 is fundamentally prevented from being lost through the central opening 201.

Both end portions of the cover handle 24 may be connected to the edge of the central opening 201, and may be formed in a shape convex upward. The cover handle 24 may be injection molded integrally with the frame 21, but a structure in which additional members are coupled is not excluded.

In addition, it should be clear that the cover handle 24 may be added in a state where the cross bar 23 is still present.

Referring to fig. 5, the laundry cover 20 according to the present embodiment is characterized in that semicircular first and

second cover parts

20a and 20b are hinged so as to be foldable, unlike the previous embodiment.

Specifically, since the outer diameter of the laundry cover 20 is greater than the inner diameter of the balancing ring 14, in order to put the laundry cover 20 inside the drum 12, the laundry cover 20 can only be bent or folded to cause shape deformation. Therefore, in order to minimize a phenomenon that the shape of the laundry cover 20 is maintained in a deformed state as the frequency of use of the laundry cover 20 increases, a structure capable of folding and unfolding the laundry cover 20 by a predetermined angle may be applied.

More specifically, the first cover part 20a and the second cover part 20b may be formed in a symmetrical shape with reference to the folding line. In addition, the folding line may be defined as a line bisecting the connection frame 214 passing through the center of the laundry cover 20. That is, the connection frame 214 through which the folding line passes may be defined to include a first connection frame and a second connection frame that are connected to each other.

In addition, as an example, the folding line may bisect the cross bar 23 formed at the central opening 201 of the inner frame 213. That is, the cross bar 23 through which the folding line passes may include a first cross bar 231 and a second cross bar 232.

The hinge assembly 25 may be mounted to the connection frame 214 through which the folding line passes. The hinge assemblies 25 may be disposed at positions spaced apart from the center of the laundry cover 20 by a predetermined interval, and may be disposed at positions symmetrical to each other from the center of the laundry cover 20. In addition, the number of the hinge assemblies 25 may be one, but in order to effectively perform a hinge function, it is preferable that at least two hinge assemblies 25 are installed at positions symmetrical to each other.

Specifically, the hinge assembly 25 may include a hinge shaft 251 provided to the first connection frame and a hinge insertion portion 252 provided to the second connection frame. The hinge assembly 25 may be formed as a part of the frame 21 so as to be injection-molded as one body, or may be coupled to the connection frame 214 using coupling members such as screws.

In addition, at the first and second cross bars 231 and 232, a coupling member 26 for selectively fixing the first and

second cover parts

20a and 20b may be formed.

Specifically, the coupling member 26 may include a hook 261 provided at either one of the first and

second rails

231 and 232 and a hook receiving part 262 provided at the other. When the laundry cover 20 is rotated about the hinge shaft 251 such that the first cover part 20a and the second cover part 20b are rotated, the hooks 261 are separated from the hook receiving parts 262, so that the laundry cover 20 can be folded. At this time, the folding angle of the laundry cover 20 may be an angle greater than 0 and less than 90 degrees.

In addition, when the first and

second cover parts

20a and 20b are rotated in order to restore the laundry cover 20 to the original position, the first coupling frame contacts the second coupling frame and the hook 261 is hooked to the hook receiving part 262. It is preferable that a coupling force is maintained in a state that the hook 261 is coupled with the hook receiving part 262 to such an extent that it is not separated by the water pressure applied to the laundry cover 20 or the pressure of the laundry during the washing process.

Here, the hook 261 and the hook receiving portion 262 are proposed as an example of the coupling member 26, but it is clear that other types of coupling members may be applied. That is, it is to be understood that a member having a function of selectively separating or combining the first cover part 20a and the second cover part 20b may be used as the coupling member of the present invention and included in the scope of the right of the present invention.

On the other hand, although the coupling member 26 is shown and described as being mounted to the cross bar 23, it is not limited thereto. For example, the coupling member 26 may be mounted to the connection frame 214 through which the folding line passes.

Alternatively, the following structure is also possible: the cover handle 24 illustrated in fig. 4 can be divided, and the connection frame 214 through which a line dividing the cover handle 24 in the width direction passes may also be divided into two parts, and the coupling member 26 is mounted on the cover handle 24. That is, the cover handle 24 may be separated into a first handle portion and a second handle portion, and the hook 261 and the hook receiving portion 262 may be provided at the end portions where the first handle portion and the second handle portion are in contact with each other.
