Description

Technology area

The present invention relates to a washing machine, and in particular to a washing machine having nozzles that spray water exiting a tub and circulating through a circulation pipe into a drum.

State of the art

In general, a washing machine is a device for removing dirt adhering to clothes, bedding, etc. (hereinafter referred to as "laundry") using the chemical decomposition of water and detergent and a physical operation such as friction between water and laundry. The washing machine includes a tub containing water and a drum rotatably mounted in the tub to accommodate laundry.

Korean Patent Application Publication No. 10-2011-0040180 (hereinafter referred to as "prior art") discloses a washing machine that circulates water discharged from a tank using a circulation pump and sprays the circulating water into a drum through a spray nozzle. The washing machine has a structure in which a distributor for distributing wash water is connected to the circulation pump, and first and second spray paths are connected to the distributor for directing wash water to the first and second spray nozzles, respectively. In addition, the spray nozzles are connected to the gasket through connectors passing through the gasket and are connected to the spray paths.

The prior art discloses a washing machine with two spray nozzles, but the washing machine is unable to uniformly wet the laundry because the spray directions are limited. In particular, although various new technologies have been developed for controlling the rotation of the drum in order to provide a variety of movements of the laundry loaded into the drum, it is difficult to expect a noticeable improvement in performance when using the traditional design.

In addition, the conventional technology has a complex structure, since the spray nozzles must be connected to the gasket by passing the connectors through the gasket, the number of spray nozzles connected to the circulation pump must match the number of spray nozzles, and multiple flow paths and multiple connectors must be connected, respectively. In addition, the manufacturing procedure is laborious due to the assembly process.

A plurality of nozzles may be provided to spray the circulating water into the drum in several directions. In this case, the structure of installing a distribution pipe for directing the circulating water to a plurality of nozzles can be considered.

In this design, the distribution pipe is designed to supply the water pumped by the circulation pump to the nozzles, and the distribution pipe can be separated from the gasket by the spray pressure of the outlet channels that release the circulating water to the nozzles or by external force from the vibration of the tank.

In addition, in the washing machine further including a drying function, the supply duct for supplying heated air to the tub and the circulating water supply pipe may interfere with each other.

In addition, a conventional washing machine is assembled in an order in which the gasket with the tub is assembled, a clip is attached to the gasket to fix the gasket to the tub, and the balancer is attached to the tub. However, the introduction of the circulating water supply tube requires a new assembly method different from the traditional assembly method.

Technical problem

A first object of the present invention is to provide a washing machine that prevents the wand, which directs the circulating water to a plurality of nozzles, from the liner due to the spray pressure of the water streams.

A second object of the present invention is to provide a washing machine that uses a balance bar provided on a front surface of a tub to prevent the wand from separating from the spacer.

A third object of the present invention is to provide a washing machine that prevents interference with the supply path provided in the heated air supply spacer and the balance bar.

A fourth object of the present invention is to provide a method for assembling a washing machine in which the spacer, wand and balance bar do not interfere with each other and are not separated when the washing machine is used.

Positive effects

The washing machine of the present invention can have one or more effects as shown below.

First, the wand pipe transport pipe is located in the space between the outer peripheral surface of the gasket body and the balance bar, and thus collision between the gasket, the wand pipe and the balance bar can be avoided, and the wand pipe can be prevented from separating from the gasket due to the spray pressure of the water jets.

Secondly, the section of the upper channel of the transport pipeline, where the upper outlet channel is located, is brought into contact with the position limiting part of the balance bar or is spaced from the position limiting part by an interval less than the length by which the upper outlet channel is inserted into the receiving tube for the upper channel. gaskets, and therefore the separation of the wand from the gasket can be prevented even without additional construction.

Thirdly, the first and second balancers, located on the front surface of the tank, are located on the left and right sides with respect to the gasket, and the upper ends of the first and second balancers are spaced from each other, in order to prevent a collision between the supply path formed in the upper parts of the spacer, and a balancer. In addition, the upper ends of the first and second pipeline portions forming the left and right sides of the transport pipeline are separated from each other to thereby prevent collisions between the supply path and the distribution pipe.

Fourth, after the distribution pipe is assembled, the distribution pipe is attached to the front surface of the tank so as to be located outside the transport pipe so that the gasket, the distribution pipe and the balance bar do not interfere with each other and do not separate when using the washing machine.

The effects of the present invention cannot be limited to the above, and other objects and other objects that are not described can be clearly understood by those skilled in the art to which this embodiment belongs through the following description.

Best Mode for Carrying Out the Invention

The advantages and features of the present invention and methods for achieving them will become apparent from the descriptions of the exemplary embodiments below with reference to the accompanying drawings. However, the present invention is not limited to the exemplary embodiments disclosed herein, but can be implemented in various ways. The exemplary embodiments are provided to make the description of the present invention detailed and fully convey the scope of the present disclosure to those skilled in the art. It should be noted that the scope of the present invention is defined only by the claims. Like reference numbers indicate like elements throughout the description.

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

FIG. 1 and 2, a washing machine according to the present invention includes a casing 10 forming an outward appearance of a washing machine, a tub 30 for holding washing water, and a drum 40 rotatably mounted in the tub 30 and containing laundry. In addition, the washing machine may include a motor (hereinafter referred to as a "driving device") for rotating the drum 40.

A front panel 11 having a laundry inlet 12 formed therein is disposed on the front surface of the cabinet 10. A door 20 for opening and closing the laundry inlet 12 is located on the front panel 11, and a detergent dispenser 14 can be installed on the front panels 11.

In addition, a water supply valve 15, a water supply pipe 16 and a water supply hose 17 are provided in the casing 10, so that the wash water supplied after passing through the water supply valve 15 and the water supply pipe 16 is mixed with the detergent in the dispenser 14 and then it is fed into the tank 30 through the water supply hose 17.

Meanwhile, the direct water supply pipe 18 may be connected to the water supply valve 15 so that wash water is supplied directly to the tub 30 through the direct water supply pipe 18 without mixing with the detergent.

In addition, a pump 70 and a wand 80 can be installed. The pump 70 and tank 30 can be connected through the outlet hose 72, and the wand 80 and the pump 70 can be connected directly to each other or through the circulation pipe 86. Accordingly, if the pump 70 is in operation, the wash water contained in the tub 30 can be sprayed into the drum 40 through the distribution pipe 80 and circulated. A pump 70 may be connected to a drain pump 74 and drain the wash water to the outside through a drain tube 74.

As described above, the pump 70 of the washing machine according to the embodiment of the present invention functions as a drain pump for draining wash water to the outside and as a circulation pump for circulating wash water. In contrast, the drain pump and the circulation pump can be installed separately, in which case it is obvious that the drain pump is connected to the drain pipe 74 and the circulation pump is connected to the circulation pipe 86.

Meanwhile, the tank 30 may be formed as a single tank body or may be formed as a combination of the first tank body 30a and the second tank body 30b connected thereto. In an embodiment of the present invention, an example is described in which the first tank body 30a and the second tank body 30b are connected to form a tank 30. Hereinafter, the first tank body 30a is referred to as the “tank” 30.

A tub 30 is disposed in the casing 10, and an opening 32 (see Fig. 4) is formed in the front of the tub 30 to match the laundry inlet 12 formed in the front panel 11.

The drum 40 for receiving laundry may be rotatably provided in the tub 30. The drum 40 receives the laundry and is positioned such that the inlet through which the laundry is loaded is located on the front surface. The drum 40 rotates about an approximately horizontal axis of rotation. In this case, "horizontal" does not apply to its mathematical definition. That is, even when the center line of rotation is inclined at a predetermined angle with respect to the horizontal state, the axis is more like a horizontal state than a vertical state, and thus the center line of revolution is considered to be substantially horizontal. The drum 40 may be provided with a plurality of through holes to introduce water contained in the tub 30 into the drum 40.

A plurality of lifters may be provided on the inner surface of the drum 40. The plurality of lifters may be positioned at a predetermined angle relative to the center of the drum 40. As the drum 40 rotates, the laundry repeatedly passes through the lifter and drop operation of the lifters.

Additionally, a drive unit 50 may be provided to rotate the drum 40. A drive shaft to be rotated by the drive unit 50 may pass through the rear of the tub 30 to connect to the drum 40.

Preferably, the drive unit 50 includes a direct drive wash motor, and the wash motor may include a stator attached to the rear of the tub 30 and a rotor rotating by a magnetic force with respect to the stator. The drive shaft 38a can rotate integrally with the rotor.

FIG. 3 and 4, a washing machine according to an embodiment of the present invention includes a gasket 60 for connecting a casing 10 and a tub 30, a plurality of nozzles 66 and 67 (see FIG. 6) for spraying water into a drum 40, a pump 70 for pumping water discharged from tank 30, and a distribution pipe 80 for directing the water pumped by the pump 70 to the nozzles 66 and 67. In addition, the washing machine may include a balancer 90 located on the front surface 31 of the tank 30, and a circulation pipe 86 for directing the water pumped pump 70, into the distribution pipe 80.

FIG. 5-9 and 15, the liner 60 includes a liner body 61 and 62 that defines a channel 60P connecting the laundry inlet 12 in the casing 10 and the opening 32 of the tub 30. An inner peripheral surface facing the central direction of the liner body 61 and 62 of the liner 60 may be referred to as the inner peripheral surface 62, and the outer peripheral surface opposite to it may be referred to as the outer peripheral surface 61.

The inner peripheral surface 62 of the napkin body may define a passage 60P connecting the laundry inlet 12 and the hole 32. The outer peripheral surface 61 of the napkin body may be opposite the inner peripheral surface of the balance bar 90. The outer peripheral surface of the napkin body 60 may be opposed to the wand 80.

The spacer 60 is made of a resilient material such as rubber and has an approximately cylindrical shape (hereinafter referred to as an annular shape). For example, spacer 60 may be formed from a substance such as ethylene propylene diene monomer (EPDM), thermoplastic elastomer (TPE), or the like, but aspects of the present invention are not limited thereto.

The spacer is located between the boundary of the front panel inlet 11, which defines the laundry inlet 12, and the boundary of the tub 30, which defines the opening 32, so that the wash water contained in the tub 30 does not flow out of the tub 30.

More specifically, since the front edge of the gasket 60 is connected to the edge of the inlet 12 of the front panel 11, and the rear edge of the gasket 60 is connected to the edge of the opening 32 of the tub 30, the gasket body 61 and 62 connecting the front and rear boundaries of the gasket 60 forms an inlet 60P for linen. If the space between the tub and the front panel is closed and the door 20 is closed, the door 20 and the front end of the pad 60 come into close contact with each other, and the space between the door 20 and the pad 60 becomes sealed to prevent water from leaking for washing.

The front end and the rear end of the spacer 60 are annular and the spacer 60 has a tubular shape extending from the front end to the rear end. The front end portion of the gasket 60 is attached to the casing 10 and the rear end portion is attached to the circumference 33 of the inlet of the tub 30. The gasket 60 may be made of a resilient or elastic material. The spacer 60 can be made from natural rubber or synthetic resin.

The gasket 60 may include a casing connecting portion 68a connected to the periphery of the casing inlet 12 of the casing 10, a tub connecting portion 68b connected around the circumference of the circumference 33 of the tub inlet 30, and a body 61 and 62 extending between the casing connecting portion 68a and the connecting portion 68b tank.

The case connecting part 68a and the tank connecting part 68b are annular. The gasket body 61 and 62 may include an annular front end connected to the case connecting portion 68a and an annular rear end connected to the tub connecting portion 68b and have a tubular shape extending from the front end to the rear end.

The circumference of the inlet 12 of the front panel 11 is turned outward, and the case connecting portion 68a can be installed in a concave region formed by the outwardly turned portion.

An annular wire winding groove may be formed in the connecting portion 61 of the casing. After winding the wire around the groove 61r, both ends of the wire are bonded, and therefore, the case connecting portion 61 is tightly fixed around the circumference of the inlet 12h.

The circumference 33 of the inlet of the tub 30, which defines the opening 32 of the tub 30, protrudes from the front surface 31 and curls outwardly, and the tub connecting portion 68b is set in the concave region formed by the outwardly curled portion. An annular groove for winding the clip 100 (see FIGS. 16 and 17) may be formed in the tank connecting portion 68b. The clip is wound around the groove and both ends of the wire are connected, and accordingly, the tank connecting portion 68b can be tightly connected to the periphery 33 of the inlet of the tank 30.

While the casing connecting portion 68a is attached to the front panel 11, the tub connecting portion 68b can move in accordance with the movement of the tub 30. Accordingly, the gasket body 61 and 62 should be able to deform in accordance with the movement of the tub connecting portion 68a. To allow the pad body to be easily transformed, the pad 60 may include a folding portion 61b between the casing connecting portion 68a and the tub connecting portion 68b (or pad bodies 61 and 62), as well as a folding portion 61b (hereinafter referred to as the "inner circumferential portion" ) collapses when the tank 30 is moved in the eccentric (or radial) direction.

The gasket body 61 and 62 may include: a rim 61a extending from the casing 10 (or the casing connecting portion 68a) to the tub 30 (or the tub connecting portion 68b) (or to the rear); an inner peripheral portion 61b bent outward from the rim portion 61a extending towards the casing 10 and bent outward again; and an outer circumferential portion 61c bent outwardly from the inner circumferential portion 61b, extending towards the tub 30 and having a diameter larger than the diameter of the rim portion 61a and the diameter of the inner circumferential portion 61b.

The gasket 60 may include an outer door contact portion 683 that is bent outwardly from the front end of the gasket body 61 and 62 to bring it into contact with the rear surface of the door 20 outside the inlet 12 to a state in which the door 20 is closed. In the case connecting portion 68a, the above-described groove may be formed in a portion extending from the outer side of the outer door contact portion 683.

The gasket 60 may include an inner door contact portion 681 that curves inwardly from the front end of the gasket body 61 and 62 to bring it into contact with the rear surface (preferably window 22) of the door 20 in a state in which the door 20 is closed.

Meanwhile, during rotation, the drum 40 vibrates (i.e., the center line of rotation of the drum 40 (see FIG. 2) moves, and accordingly, the center line of the tub 30 (approximately identical to the center line of rotation of the drum) 40) also moves. In this case, the direction of movement (hereinafter referred to as "eccentric direction") has a radial direction component.

The front side of each of the inner peripheral part 61b and the outer peripheral part 61c can be folded or unfolded when the tub 30 is moved in the eccentric direction. When a portion of the inner circumferential portion 61b is folded as the center of the tub 30 moves in the eccentric direction, the distance between the inner circumferential portion 61b and the outer circumferential portion 61c decreases in this portion, while the distance between the inner circumferential portion 61b and the outer circumferential portion 61c is enlarged in another portion in which the inner peripheral portion 61b is unfolded.

FIG. 8 and 9, the gasket 60 includes an enclosing portion 610 on which is located at least a portion of the transport conduit 81 and 82, which will be described below. The pad body 61 and 62 is divided into a front body located on the casing 10 side and a rear body located on the tub 30 side. The receiving portion 610 may be formed at the rear of the pad body.

The receiving portion 610 may include a boundary surface 612 extending inwardly from the rear end of the forward nap body 61ad 62. The boundary surface 612 can be curved from the rear end of the front napkin body and extend inwardly. The boundary surface 612 may be located at a boundary that separates the pad body 61 and 62 into a front body and a rear body.

The receiving portion 610 includes an opposing surface 611 extending rearwardly from the boundary surface 612. The opposing surface 611 curves from the inner end of the boundary surface 611 and opposes the inner surface of the transport conduit 81 and 82.

An opposing surface 611 extends from the rear of the liner body 61 and 62 in the circumferential direction of the liner body 61 and 62. The boundary surface 612 extends toward the outside of the radial direction from the opposite surface 611. The boundary surface 612 is connected to the front of the pad body 61 and 62.

The receiving portion 610 can be formed to be farther inward than the portion adjacent to the front of the living portion 610. The receiving portion 610 can be formed such that a portion of the outer peripheral surface 61 of the pad 60 is recessed inwardly, or such that the portion the outer peripheral surface 61 of the spacer 60 protrudes (or rises) to form an enclosing portion 610 is formed on one side of the protruding portion.

As described above, while the drum 40 rotates, the tub 30 vibrates. Due to the vibration of the tub 30, the spacer 60 formed from the elastic material may fold or unfold, and vibration is generated accordingly.

The upper channel sections 81a and 82a may form the left and right upper ends of the transport pipeline. The upper channel section 81a of the first pipeline part and the upper channel section 82a of the second pipeline part can be separated from each other. Thus, although the diameter of each of the outlet ducts 83 and 84 is larger than the inner diameter of each of the duct receiving pipes 63 and 64, the upper outlet ducts 83a and 84a may be separated from the upper duct receiving pipes 63a and 64b. A washing machine according to an embodiment of the present invention has a balance bar 90 located outside the transport lines 81 and 82 to thereby prevent the wand 80 from separating. These will be described in detail below.

In addition, the protrusions 65 and nozzles 66 and 67 may be omitted to spray water from the outer passages 83 and 84 into the drum 40 without them. In addition, the nozzles 66 and 67 may be formed separately from the gasket 60 and must be connected to or spaced from the gasket 60.

Meanwhile, as shown in FIG. 3 and 5, one end of the circulation pipe 86 is connected to an inlet 85 protruding from the bottom of the distribution pipe 80, and the other end of the circulation pipe 86 may be connected to the circulation passage 78 of the pump 70. In the case where the circulation passage 78 of the pump 70 is formed in position facing the inlet in a straight line, the circulation tube 86 may be in the form of a straight tube. However, in other cases, the circulation tube 86 may be formed as a hose made of flexible material, or may be formed by bending.

The circulation tube 86 can be formed from a substance that is flexible but able to maintain its shape. In an embodiment of the present invention, the circulation pipe 86b may be made of ethylene propylene diene monomer rubber (EPDM). The circulation tube 86 may contain a bellows.

FIG. 11, 12 and 13, pump 70 can selectively function to pump water discharged through drain hose 72 to drain tube 74 and pump water to circulation tube 86. Pump 70 can be located under tank 30. Pump 70 can pump water discharged from tank 30. As described above, the pumped water, directed to the distribution pipe 80 through the circulation pipe 86, and then sprayed into the drum 40, is called the circulation water.

The pump 70 may include a pump housing 71, a first pump motor 73, a first impeller 715, a second pump motor 75, and a second impeller 717. The pump 70 may include a circulation channel 78 and a drain channel 76 that protrude from the housing 71 pump and discharges the water leaving the tank 30.

The pump inlet 711 may be formed in a pump housing 71. In the pump housing 71, a first chamber 714 may be formed to receive a first impeller 715 and a second chamber 716 to receive a second impeller 717. The first impeller 715 is rotated by the first pump motor 73 and the second impeller 717 is rotated by the second pump motor 75.

The first chamber 716 and circulation channel 78 define a spiral shaped flow path that rotates in the direction of rotation of the first impeller 715. The second chamber 716 and drain channel 76 define a spiral shaped flow path that rotates in the direction of rotation of the second impeller 717. Here, the direction of rotation of each the impeller 715 and 717 is controlled and given. The pump inlet 711 is connected to an outlet hose 74, and the first chamber 714 and the second chamber 716 communicate with the pump inlet 711. Water discharged from tank 30 via drain hose 74 is supplied to first chamber 714 and to second chamber 716 via pump inlet 711.

The first chamber 715 communicates with the circulation channel 78 and the second chamber 716 communicates with the drain channel 76. Thus, when the first impeller 715 rotates during the operation of the first pump motor 73, the water contained in the first chamber 714 is discharged through the circulation channel 78. In addition, In addition, if the second pump motor 75 is running, the second impeller 717 rotates and, accordingly, the water contained in the second chamber 716 is drained through the drain passage 76. The circulation passage 78 is connected to the circulation pipe 86, and the drain passage 76 is connected to the drain pipe 74.

FIG. 3 and 4, a washing machine according to an embodiment of the present invention includes a balance bar 90 disposed on the front surface 31 of the tub 30. The balance bar 90 may be attached to the front surface 31 of the tub 30. The balance bar 90 is used to reduce vibration of the tub 30, and the balance bar 90 is a weighting agent having a given weight. The balancer 90 may include one or more balancers 90 located around the circumference of the front surface 31 of the tank 30.

The balancer 90 of the washing machine according to the first embodiment of the present invention may include a first balancer 91 and a second balancer 92 disposed on the left and right sides of the front surface 31 of the tub 30, respectively. The first balancer 91 may be located on the left side of the pad 60, and the second balancer 92 can be located on the right side of the gasket 60.

When the pad body 61 and 62 is divided on both sides into a first region and a second region, the first balance bar 91 may be located outside the first region and the second balance bar 92 may be located outside the second region.

The first rocker 91 and the second rocker 92 can be spaced apart on both the upper and lower sides. The first and second balancers 91 and 91 may be bilaterally symmetrical about a vertical line OV through the center O of the spacer 60 and may be positioned symmetrically on either side of the vertical line.

Hereinafter, with reference to FIG. 13, 14 and 15, the arrangement of the gasket 60, the wand 80 and the balance bar 90 will be described.

At least a portion of the balance bar 90 is spaced from the outer peripheral surface 61 of the pad body 61 and 62. At least a portion of the transport conduit 81 and 82 is located in the space between the outer peripheral surface 61 of the pad body 61 and 62 and the balance bar 90.

At least a part of the first pipeline part 81 is located in the space between the outer peripheral surface 61 of the first region and the first balance bar 91, and at least part of the second pipeline part 82 is located in the space between the outer peripheral surface 61 of the second region and the second balance bar 92.

The first balance bar 91 and the second balance bar 92 may be bilaterally symmetrical. Thus, the first balance bar 91, the distributor 80 and the left side of the spacer 60 will be described below, while the description of the second balance bar 92, the distribution tube 80 and the right side of the spacer 60 will be partially omitted.

The upper channel section 81a, the upper guide section 81c, the middle guide section 81d and the lower channel section 81b of the transport conduit 81 are located in a space where the first balance bar 91 and the outer peripheral surface 61 of the pad body are spaced apart. The curved section 81e may be located in the space between the first balance bar 91 and the outer peripheral surface 61 of the napkin body. A part (upper part) of the lower guide 81f may be located in the space between the first balance bar 91 and the outer peripheral surface 61 of the pad body.

Accordingly, the first balance bar 91 may be located outside of the first region and extend from the top of the first upper channel section 81a to the bottom of the first lower channel section 81b. The second balancer 92 may be located outside the second region and extend from a position above the second upper channel section 82a to a position below the second lower channel section 82b.

The balancer 90 may include a position limiting portion 90p that prevents the upper outlet 83a and 84b from separating from the receiving tubes 63a and 64a for the upper channels. The position limiting part of the first rocker 91 is referred to as the first position limiting part 91p, and the position limiting part of the second rocker 92 is referred to as the second position limiting part 92p. The first position limiting portion 91p may be provided at a position corresponding to the first upper channel section 81a. The first position limiting portion 91p may be spaced from the outer circumferential surface 61 of the pad body. The first position limiting portion 91p may be outwardly separated from the outer circumferential surface 61 of the pad body.

The section 81a of the first upper channel of the transport conduit 81 may be located in the space between the outer peripheral surface 61 of the pad body and the first position limiting portion 91p. By adjusting the interval between the first position limiting portion 91p and the outer circumferential surface of the napkin body, or the interval between the first position limiting portion 91p and the first upper channel section 81a, it is possible to prevent the first upper outlet channel 83a from separating from the receiving tube 63a for the first upper channel.

The transport conduit 81 and 82 includes an inner surface opposite the outer peripheral surface 61 of the pad body and an outer surface opposite the inner surface. The balancer 90 includes an inner surface opposite the outer peripheral surface 61 of the pad body. The outer surface of at least a portion of the transport conduits 81 and 82 is located opposite the inner surface of the balance bar 90.

The upper channel sections 81a and 82a may include channel surfaces 81a1 and 82a1 where the upper outlet channels 83a and 84a are located, and abutment surfaces 81a2 and 82a2 opposite the channel surfaces 81a1 and 82a1. That is, the transport conduit 81 and 82 includes an inner surface of the gasket body 61 and 62 and an outer surface of the balance bar 90. The abutment surfaces 81a2 and 82a2 refer to the outer surface of the top pore sections 81a and 82a.

Further, the channel surface 81a1 and the abutment surface 81a2 of the first upper channel section 81a are respectively referred to as the first upper channel surface 81a1 and the first abutment surface 81a2, and the channel surface 82a1 and the abutment surface 82a2 of the second upper channel section 82a are respectively referred to as the second upper channel surface 82a1, and the second abutment surface 82a2.

The first portion 91P limiting the position of the first balance bar 91 can come into contact with the first abutment surface 81a2. Alternatively, the first balance bar 91 may be positioned such that the interval between the first position limiting portion 91P and the first abutment surface 81a2 is shorter than the length L by which the first upper outlet 83a is inserted into the receiving tube 63a for the first upper channel.

The first abutment surface 81a2 may come into contact with the first position limiting portion 91p. Alternatively, the first abutment surface 81a2 may be located at a distance from the first position limiting portion 91P, and the interval between the first abutment surface 81a2 and the first position limiting portion 91P may be shorter than the length L by which the first upper outlet port 83a is inserted into the receiving tube 63a for the first upper channel.

The second portion 92p of limiting the position of the second rocker 92 can come into contact with the second abutment surface 82a2. Alternatively, the second balancer 92 may be positioned such that the interval between the second position limiting portion 92p and the second abutment surface 82a2 is shorter than the length L by which the first upper outlet 84a is inserted into the receiving tube 64a for the first upper channel.

The second abutment surface 82a2 may come into contact with the second position limiting portion 92p. Alternatively, the second abutment surface 82a2 may be located at a distance from the second position limiting portion 92p, and the interval between the second abutment surface 82a2 and the second position limiting portion 92p may be shorter than the length L by which the second upper outlet 84a is inserted into the receiving tube 64a for the second upper channel.

Accordingly, it is possible to prevent the upper outlet ducts 83a and 84a from separating from the receiving tubes 63a and 64a for the upper duct.

The balance bar 90 may be located outside the pad body 61 and 62, and the inner surface of the balance bar 90 may have a convex shape and surround a portion of the outer peripheral surface 61 of the pad body. The first balance bar 91 may surround a portion of the first region, and the second balance bar 92 may surround a portion of the second region. The first and second position limiting portions 91p and 92p may be provided at locations corresponding to the first and second upper outlet ducts 83a and 84a, respectively, and the first and second upper outlet ducts 83a and 84a may be located higher than the center O of the body 61 and 62 gaskets. Accordingly, the inner surfaces of the first and second position limiting portions 91p and 82p can be inclined away from the vertical line OV passing through the center O of the pad body 61 and 62 from the top side to the bottom side.

The first abutment surface 81a2, which is the outer surface of the first upper channel section 81a, and the inner surface of the first position limiting portion 91p are opposite each other. The second abutment surface 82a2, which is the outer surface of the receiving section 82a for the second upper channel, and the inner surface of the second position limiting portion 92p are opposite to each other. Accordingly, the first and second abutment surfaces 81a2 and 82a2 can be inclined in a direction away from the vertical line OV from the upper side to the lower side.

Meanwhile, the first position limiting portion 91p may include a protrusion that is formed on the inner surface of the first position limiting portion 91p and protrudes towards the first upper channel section 81a or 82a or towards the liner body 61 and 62. The protrusion of the first position limiting portion 91P may come into contact with the first abutment surface 81a2, which is the outer surface of the first upper channel section 81a. In addition, the inner surface of the second position limiting portion 92p may include a protrusion that is formed on the inner surface of the second position limiting portion 92p and projects toward the second upper channel section 82a or toward the liner body 61 and 62. The protrusion in the second position limiting portion 92p may come into contact with the second abutment surface 82a2.

The first abutment surface 81a2 of the first upper channel section 81a and the inner surface of the first position limiting portion 91P of the first balance bar 91 opposite to the first abutment surface 81a2 are inclined in the same direction. The second abutment surface 82a2 and the inner surface of the second position limiting portion 92p are inclined in the same direction. Accordingly, the balance bar 90 can stably support the wand 80, and the wand 80 can be prevented from separating from the spacer 60.

Meanwhile, the balance bar 90 has the advantage of preventing the wand 80 from separating when using the washing machine. However, when the washing machine needs to be repaired, the balance bar 90 can make it difficult to separate the wand 80 from the gasket 60.

The lower outlet ports 83b and 84b may be located below the upper outlet ports 83a and 84a. The position limiting portions 91p and 92p prevent the spacing between the upper ends of the lower outlet ports 83b and 84b from increasing. Thus, while the lower channel sections 81b and 82b are not supported by the balance bar, the lower outlet channels 83b and 84b are less likely to be separated from the lower channel receiving tubes 63b and 64b. Accordingly, the inner surface of the balance bar 90 and the outer surface of each of the lower channel sections 81b and 82b can be spaced apart.

The interval between each of the lower channel sections 81b and 82b and the balance bar 90 may be greater than the interval between each of the upper channel sections 81a and 82a and the balance bar 90. That is, the interval between the outer surface of the first lower channel section 81b and the inner surface of the first balance bar 91 may be greater than the interval between the first abutment surface 81a2 and the first position limiting portion 91P. The interval between the outer surface of the second lower channel section 82b and the inner surface of the second balance bar 92 may be greater than the interval between the second abutment surface 82a2 and the second position limiting portion 92p.

In addition, the spacer 60 may be formed of a resilient material, and thus, although the spacing between each of the lower channel sections 83b and 84b and the balance bar 90 is slightly less than the length by which the lower outlet channels 83b and 84b are inserted into the receiving tubes 63b and 64b for the lower channels, it is possible to forcefully separate the lower outlet channels 83b and 84b from the receiving tubes 63b and 64b for the lower channels.

Accordingly, when the washing machine needs to be repaired, it is possible to separate the lower outlet ducts 83b and 84b from the receiving tubes 63b and 64b for the lower channels without separating the balance bar 90 from the tub 30, and then separate the upper outlet channels 83a and 84a from the receiving tubes 63a and 64a. for the upper channels.

Hereinafter, with reference to FIG. 16 and 17, a method for assembling a washing machine according to a first embodiment of the present invention will be described.

First, the gasket 60 is assembled with the front surface 31 of the tub 30. The tub 30 has an inlet circumference 33 that defines an opening 32. The gasket 60 may include a tub connection 68b recessed around the inlet circumference 33.

The tub connecting portion 68b includes an outer tub connecting portion 68b1 protruding from the rear end of the gasket body 61 and 62, and an inner tub connecting portion 68b2. The outer tank connecting part 68b1 protrudes further from the outside than the inner tank connecting part 68b2, and a groove is formed between the outer tank connecting part 68b1 and the inner tank connecting part 68b2 into which the inlet circumference 33 of the tank is inserted.

The inner tub-connecting portion 68b2 extends rearwardly from the rear end of the pad body 61 and 62 and then curves inwardly. The outer tub connecting portion 68b1 protrudes from the rear end of the pad body 61 and 62 and bends inwardly and then outwardly.

The circumference 33 of the inlet of the tub 30 protrudes from the front surface 31 and is bent outward. The outwardly curved portion of the inlet circumference 33 engages with the inwardly curved portion of the outer tank connecting portion 68b1. When the front surface 31 of the tank 30 is to be assembled with the gasket 60, the circumference 33 of the inlet hole fits into a groove formed between the outer tank connecting part 68b1 and the inner tank connecting part 68b2.

Although the circumference 33 of the inlet of the tub 30 and the tub connecting portion 68b of the pad 60 are connected, there are possibilities that the pad 60 may be detached due to vibration of the tub 30 and that the wash water contained in the tub 30 may flow through the gap between the circumference. 33 inlet and the tank connecting part 68b. Therefore, it is necessary to more tightly secure the gasket 60 to the tank 30.

The gasket 60 is assembled with the front surface of the tank 30 and is fixed by the ring clip 100. The outer tank connection portion 68b2 is curved inwardly and curved outward to form a groove on the outside, a groove into which the clip is inserted.

The clamp 100 includes an arcuate clamping wire 101, both ends of which are open, and a spring 103 that resiliently connects both ends of the clamping wire 101. The clamping wire 101 is placed in a groove formed in the outwardly extending tank connecting portion 68b1, and the spring 103 is connected to both ends clamping wire 101, thereby fixing the gasket 60 to the tank 30.

Gasket 60 is attached to tank 30 by clamp 100, and wand 80 is assembled with gasket 60 assembled with tub 30. Wand 80 can be assembled with gasket 60 by inserting a plurality of outlet ports 83 and 84 into a plurality of receiving pipes 63 and 64 to channels protruding from the outer peripheral surface 61 of the pad body. The transport conduit 81 and 82 of the distribution tube 80 may be located on the outer peripheral surface 61 of the pad body.

The diameter of the outlet 83 or 84 is slightly larger than the inner diameter of the receiving tube 63 or 64 of the channel, so that the outlet conduit 83 or 84 can be pressed into the receiving tube 63 or 64 for the channel.

Meanwhile, in contrast to the above description, the gasket 60 can be assembled with the tank 30, the wand 80 can be assembled with the gasket 60 assembled with the tank 30, and the gasket 60 assembled with the wand 80 can be assembled with the tank 30 with clamp 100.

The spacer 60 can be attached to the tub 30, the distribution tube 80 can be assembled with the spacer 60, and the balance bar 90 can be attached to the front surface 31 of the tub 30. The balance bar 90 can be located outside of the outer peripheral surface 61 of the spacer body. In addition, the balance bar 90 can be located outside the transport pipe 81. That is, the transport pipe 81 can be located between the outer peripheral surface 61 of the pad body and the balance bar 91.

The balancer 90 includes position limiting portions 91p and 92p that prevent wand 80 from separating from the spacer 60. Position limiting portion 91p and 92p may be positioned to engage with bearing surfaces 81a2 and 82a2, which are the outer surfaces of sections 81a and 82a the upper channel of the transport conduit 81 and 82. Alternatively, the balance bar 90 may be positioned such that the position limiting portions 91p and 92p are spaced from the bearing surfaces 81a2 and 82a2 of the conveying conduit 81 and 82. The spacing between the position limiting portions 91p and 92p, located at a distance from the support surfaces 81a2 and 82a2 of the transport conduit 81 and 82, may be shorter than the length by which the first outlet 83a is inserted into the receiving tube 63a for the first upper channel.

By final assembly of the balance bar between spacer 60, clamp 100, distribution tube 80 and balancer 90, tank 30, spacer 60, clamp 100, distribution tube 80 and balancer can be easily assembled. 90.

FIG. 18, 19 and 20, the washing machine according to the second embodiment of the present invention can provide a drying function as well as a washing function. The washing machine may include a dry heater for heating the air and a fan for supplying air heated by the heater to the inside of the tub 30. After the washing operation, the drying heater and blower may be operated to dry the laundry in the drum 40.

The washing machine according to the second embodiment of the present invention may further include a supply path for supplying air to the tub 30 with a blower. The delivery path 69 may be integral with the spacer 60. Alternatively, the delivery path 69 may be formed in the tank 30. In the present embodiment, the delivery path 69 is an opening that is formed in the spacer 60 and allows entry to the inside and outside of the tank 30. The delivery path the path 69 may interfere with the distribution tube 80 and the balancers 91 and 92 located on the outer peripheral surface 61 of the pad body. Next, a structure for reducing the mutual influence between them will be described.

A supply path 69 may be formed in the gasket 60 for supplying the air blown by the blower into the tank 30. The supply path 69 may be formed on the upper side of the body 61 and 62 of the gasket. The spacer 60 differs from the spacer 60 according to the above-described embodiment in that it further comprises a supply path 69. Unless otherwise indicated, the components and structures of the above-described embodiments may be used.

The distribution tube 80 may be positioned to surround at least a portion of the outer peripheral surface 61 of the napkin body. In particular, in the surrounding area defined by the closed curved line surrounding the outer peripheral surface 61 of the napkin body, the transport conduit 81 and 82 may be located in a partial area thereof, but not in other areas. Other areas in the surrounding area in which the transport conduits 81 and 82 are not located may be defined as unreported area 690.

In particular, the transport conduit 81 and 82 of the wand 80 may include a first conduit portion 81, one end of which is connected to an inlet 85, and a second conduit portion 82, which has one end connected to an inlet 85 and a first conduit portion 81. ... The other end 81a of the first pipeline portion 81 and the other end 82a of the second pipeline portion 82 may be spaced apart.

The space between the other end 81a of the first pipeline portion 81 and the other end 82a of the second pipeline portion 82 is defined as a gap 88. The gap 88 is positioned to overlap the device-free region 690. The shape of wand 80 can reduce interference between wand 80 and delivery path 69.

An area 690 without devices may be located in a surrounding area above the center O of the casing 61 and 62 of the spacer.

The delivery path 69 can be located on the upper side of the body 61 and 62 of the napkin. When the liner body 61 and 62 is divided into four regions with respect to the center O of the liner body 61 and 62, the top side of the liner body 61 and 62 may be in the region above other regions. Alternatively, the upper side of the liner body 61 and 62 may refer to an area including one of two points at which a vertical line OV passing through the center O of the liner body 61 and 62 meets the liner body 61 and 62.

In addition, the tops of the liner body 61 and 62 may be positioned to partially cover the device-free region 690.

The supply path 69 may be located in the gap 88 between the other end 81a of the first pipe section 81 and the other end 82a of the second pipe section 82. The inlet 85 may be located on the underside of the transport duct 81 and 82, and the first portion 81 and the second portion 82 of the transport duct 81 and 82 may be connected to each other at the section where the inlet 85 is located, and the first portion 81 of the pipeline and the second part 82 of the pipeline are separated from each other on the upper side. Thus, the other ends 81a and 82a of the first and second pipeline portions 81 and 82 may be referred to as the upper ends 81a and 82a of the first and second pipeline portions 81 and 82. That is, the supply path 69 may be located in the space between the upper ends 81a and 82a of the first and second pipe portions 81 and 82. Since the supply path 69 is located in the space 99 where the upper ends 81a and 82a of the first and second pipe portions 81 and 82 are spaced apart, the distribution pipe 80 and the supply path 69 do not collide with each other.

The balance bar 90 may be disposed outside of the pad body 61 and 62 on the front surface 31 of the tub 30. In particular, when the pad body 61 and 62 is split from two sides into a first region and a second region, the balance bar 90 may include a first balance bar 91 located outside the first region, and a second balancer 92 located outside the second region. The first part 81 of the pipeline is located between the first balancer 91 and the outer peripheral surface 61 of the pad body, and the second part 82 of the pipeline is located between the second balancer 91 and the outer peripheral surface 61 of the pad body, and, accordingly, the first and second balancers 91 and 92 can be spaced from the outer the peripheral surface 61 of the pad body.

The upper end of the first rocker 91 and the upper end of the second rocker 92 can be spaced apart, and the rocker 90 cannot be located outside the upper side of the pad body 61 and 62. At least a portion of the device-free region 690 may be positioned so as not to overlap the upper side of the pad body 61 and 62, in which the balance bar 90 is not located. Accordingly, it is possible to reduce the mutual influence between the supply path 69 located in the device-free region 690, and the first and second balancers 91 and 92.

The supply path 69 may be located in the space between the upper end of the first rocker 91 and the upper end of the second rocker 92.

In addition, the washing machine may include a balance bar 90 located on the front surface 31 of the tub 30 and a circulation tube 860 for directing the water pumped by the pump 70 to the distribution tube 800.

The washing machine according to the third embodiment of the present invention differs from the washing machine according to the first embodiment of the present invention in terms of the structure of the distribution pipe 800, the balance bar 90, the pump 70, and the circulation pipe 860, but is identical to the first embodiment except for the structure. Thus, unless otherwise indicated, the same configuration and structures can be applied to the third embodiment.

FIG. 21, the balance bar 90 of the washing machine according to the third embodiment of the present invention includes an upper balance bar 93 and a lower balance bar 94, which are disposed on the front surface 31 of the tub 30 and are vertically separated from each other. An upper balancer 93 is located on the upper side of the pad body 61 and 62, and a lower balancer 94 is located on the lower part of the pad body 61 and 62. Hereinafter, the upper rocker 93 and the lower rocker 94 may be referred to as the first rocker 93 and the second rocker 94.

The first rocker 93 and the second rocker 94 can be vertically spaced from each other. The first and second balancers 93 and 94 may be vertically spaced from each other on the left and right sides of the pad body 61 and 62.

The distribution pipe 800 of the washing machine according to the third embodiment may include a first distribution pipe 801 and a second distribution pipe 802, which are disposed on the left and right sides of the pad 60. The first distribution pipe 801 may supply water pumped by the pump 70 to the first nozzle 66. and the second wand 802 can supply water pumped by the pump 70 to the second nozzle 67.
