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

1 and 2 are perspective views illustrating a dishwasher according to an embodiment of the present invention. At this time, FIG. 1 shows a state in which the door 3 is closed, and FIG. 2 shows a state in which the door 3 is opened. 3 is a perspective view illustrating a state in which an outer panel of a door is removed from the dish washing machine of FIG. 1;

1 to 3, the dishwasher selectively includes a housing 1 forming an exterior, a washing tub 2 provided inside the housing 1 and forming a washing space 21, and a washing space 21. A door 3 that opens and closes, a base 4 supporting the washing tank 2, a rack 5 provided inside the washing tank 2 and accommodating objects to be washed, a sump for storing washing water (not shown), a washing tank ( 2) It may include a spray arm 6 provided inside and spraying washing water toward the washing object, and a sealing part 100 installed between the washing tank 2 and the door 3 to prevent the washing water from leaking.

The washing tub 2 forms a washing space 21 therein, and may have a shape with one surface open. The open side may be selectively opened and closed by a door (3).

Hereinafter, for convenience of explanation, the direction in which the open side of the washing tub 2 is located will be defined as 'front' of the washing tub 2. That is, 'forward' means the positive direction of the X-axis, and 'reverse' means the negative direction of the X-axis. In addition, 'side' of the washing tub 2 means the Y-axis direction, 'upward' means the positive direction of the Z-axis, and 'downward' means the negative direction of the Z-axis.

The washing tank 2 may include a washing tank bottom 23 forming the bottom of the washing space 21, a pair of side walls, a rear wall, and a ceiling. A filter 7 inserted into the sump and a spray arm 6 may be coupled to the bottom 23 of the washing tank. In addition, a sealing unit 100 to be described below may be mounted on the bottom 23 of the washing tub.

The door 3 is rotatably connected to the housing 1 to selectively open and close the washing space 21 . For example, as shown in FIG. 2 , a lower portion of the door 3 may be hinged to the housing 1 . In this case, the door 3 can open and close the washing tub 2 by rotating around the lower part.

On the other hand, since the door 3 must be able to rotate, a free space for rotation is required. Therefore, the space between the washing tub 2 and the door 3 may not be completely sealed. More specifically, a gap may be formed between the washing tank bottom 23 and the door 3, and washing water may flow out through the gap. In the present invention, by installing the sealing part 100 in the gap, the washing water can be prevented from leaking. This will be described later.

In one embodiment, the door 3 includes an inner panel 31 provided on the side of the washing space 21, and an outer panel 33 facing the inner panel 31 and forming the exterior of the door 3. can include When the door 3 is closed (see FIG. 1), the outer panel 33 is exposed to the outside, and when the door 3 is opened (see FIG. 2), the inner panel 31 is exposed to the outside.

An opening 32 for accommodating the detergent box 37 is formed on an outer surface of the inner panel 31, and a sealing unit 100 may be coupled to the inner surface. At this time, the outer surface of the inner panel 31 means a surface in contact with the washing space 21, and the inner surface of the inner panel 31 means a surface opposite to the outer surface.

A control panel 8 for controlling the dishwasher may be provided on the outer panel 33 . The control panel 8 includes a power switch 81 for turning on/off the power of the dishwasher, a manipulation unit 83 for allowing the user to input commands for controlling the dishwasher, and a display unit 85 for displaying the operation status of the dishwasher. etc. may be included.

The base 4 is provided below the housing 1 and can support the washing tub 2 to be located at a certain height. A predetermined space is formed inside the base 4, and various mechanical devices such as the sump and a steam generator may be accommodated in the space.

The rack 5 accommodates objects to be washed, and at least one may be provided inside the washing tub 2 . That is, although only one rack 5 installed above the washing tub 2 is shown in FIG. 2, this is for convenience of description and the present invention is not limited thereto. For example, a dishwasher may include two or more racks spaced vertically apart.

The rack 5 may be drawn out of the washing tank 2 through the open side of the washing tank 2 . The user may receive a washing object or collect a washing object after washing by pulling the rack 5 out of the washing tub 2 .

The sump may receive and store water supplied from the outside and circulate the stored water within the dishwasher. Specifically, the water stored in the sump may be sprayed to a washing object stored in the rack 5 through the spray arm 6 . The sprayed water may fall to the bottom 23 of the washing tank and be returned to the sump through the filter 7 .

The spray arm 6 is rotatably mounted on the bottom 23 of the washing tub, and can spray washing water toward a washing object stored in the rack 5. At this time, since the spray arm 6 sprays the washing water while rotating, the spray range of the washing water can be increased compared to the case where the washing water is sprayed in a stationary state. Accordingly, the washing effect of the dishwasher may be increased.

Meanwhile, the washing water sprayed from the spray arm 6 collides with a washing object accommodated in the rack 5 and then falls to the bottom 23 of the washing tub. However, since the washing water is sprayed in various directions and the shape of the washing object is not constant, the falling washing water may form a flow in various directions. Among them, washing water flowing towards the filter 7 can be directly recovered into the sump, and washing water flowing towards the side wall or rear wall of the washing tank 2 has little fear of leaking out of the dishwasher.

However, since the door 3 and the washing tub bottom 23 are not completely sealed and a slight gap is formed, washing water flowing toward the open surface of the washing tub 2 may flow out of the dishwasher. In the present invention, the sealing unit 100 is installed between the inner panel 31 of the door 3 and the bottom 23 of the washing tank to prevent such washing water from leaking out. Hereinafter, the sealing unit 100 will be described in more detail.

FIG. 4 is an enlarged view illustrating part A of FIG. 3 . 5 and 6 are a perspective view and a front view of the bottom of the washing tub, respectively. 7 and 8 are a perspective view and a front view of the sealing part, respectively. 9 is a cross-sectional view of the sealing portion of FIG. 7 taken along line VI-VI'. 10 is a cross-sectional view illustrating a sealing unit according to another embodiment.

First, referring to FIGS. 5 and 6 , the washing tub floor 23 includes a bottom surface 231 forming the bottom of the washing space 21 and a blocking wall 233 bent upward from an end of the bottom surface 231. , a pair of side walls 237 and a rear wall. That is, the blocking wall 233 means a wall surface formed at the front end of the washing tub bottom 23 . Due to the bottom surface 231, the blocking wall 233, the side wall 237, and the rear wall, the washing tub bottom 23 can accommodate a certain amount of washing water. The washing water received in the washing tank bottom 23 may be returned to the sump through the filter 7 .

However, in some cases, the washing water may exceed the storage capacity of the washing tank bottom 23 . For example, when the filter 7 is clogged with foreign substances and the recovery of washing water to the sump is not smooth, or when the amount of washing water sprayed is too large. In this case, washing water may flow out of the dishwasher beyond the barrier wall 233 .

In order to prevent this, at least one discharge part 235 may be provided in the blocking wall 233 . 5 and 6 show two discharge units 235 spaced apart from each other on both sides of the blocking wall 233, but are not limited thereto. That is, the location and number of the discharge units 235 may be variously changed as needed.

The discharge unit 235 is provided on the blocking wall 233 , and the height of the upper surface thereof may be lower than that of the upper surface of the blocking wall 233 . Accordingly, the washing water may be discharged to the discharge unit 235 before exceeding the storage capacity of the washing tank bottom 23 .

A drip tray 13 may be installed below the discharge unit 235 . The water tray 13 may be supported by the lower frame 11 that is part of the housing 1. The water tray 13 may guide the washing water discharged through the discharge unit 235 to the inside of the base 4 .

Referring to FIGS. 7 to 9 , the sealing unit 100 includes a first coupling unit 110 coupled to the blocking wall 233 of the washing tank bottom 23 and a second coupling unit 120 coupled to the door 3. ), a body 130 connecting the first coupling portion 110 and the second coupling portion 120, and a seal extending downward from the body 130 and contacting the bottom surface 231 of the washing tub bottom 23. may contain ribs.

The first coupling part 110 may be mounted on the blocking wall 233 to fix the sealing part 100 to the bottom 23 of the washing tub. At this time, a plurality of ribs may be formed on the inner surface of the first coupling part 110 . The ribs increase the coupling force between the first coupling portion 110 and the blocking wall 233, thereby preventing the sealing portion 100 from being separated from the washing tank bottom 23 when the door 3 is opened and closed. In addition, the ribs can prevent the washing water from leaking out beyond the barrier wall 233 .

In one embodiment, the first coupling part 110 extends along the longitudinal direction of the blocking wall 233 but may be provided so as not to cover the discharge part 235 . This is to prevent discharging of the washing water through the discharge unit 235.

For example, as shown in FIG. 6 , when a pair of discharge parts 235 are spaced apart from each other on both sides of the blocking wall 233, the first coupling part 110 is the pair of discharge parts 235 can be formed between That is, the length (L1, see FIG. 8) of the first coupling part 110 may be smaller than the gap (D, see FIG. 6) between the discharge parts 235.

Unlike this, when the discharge part 235 is provided in the center of the blocking wall 233, the first coupling part 110 may have a shape in which the center is cut.

The second coupling part 120 may be coupled to the door 3 to fix the sealing part 100 to the door 3 . For example, as shown in FIG. 4 , the second coupling part 120 may be inserted into the fixing part 35 provided in the door 3 . Accordingly, when the door 3 rotates, the second coupling part 120 can rotate together with the door 3 .

In one embodiment, the second coupling part 120 may be provided at a higher position than the first coupling part 110 .

Since the washing tub bottom 23 is fixed, the position of the first coupling part 110 mounted on the washing tub bottom 23 may not change. On the other hand, since the door 3 rotates to selectively open and close the washing space 21 , the second coupling part 120 coupled to the door 3 can rotate together with the door 3 . In this case, since the second coupling portion 120 is positioned at a higher position than the first coupling portion, deformation of the body 130 when the door 3 is opened can be minimized. Accordingly, even if the door 3 is repeatedly opened and closed, the effect of blocking the washing water of the sealing unit 100 may be maintained.

The body 130 connects the first coupling part 110 and the second coupling part 120, and can prevent the washing water from leaking out through the space between the door 3 and the washing tub bottom 23. . In addition, the body 130 can improve the user's satisfaction by blocking noise inside the washing tub 2.

The body 130 may extend to both side walls 237 of the washing tank bottom 23 and contact both side walls 237 . Accordingly, the outflow of washing water through the side wall 237 can be prevented.

Meanwhile, as shown in FIG. 11 , a connection portion between the blocking wall 233 and the sidewall 237 may be rounded to have a predetermined curvature. At this time, the edge of the body 130 is also rounded to have a predetermined curvature, so that the blocking wall 233 and the side wall 237 can be closely adhered to the connection portion. Accordingly, the washing water blocking effect can be maximized.

In one embodiment, the body 130 may be formed of a material having elasticity. For example, the body may be formed of rubber, silicon, or the like. Accordingly, the shape of the body 130 can be flexibly deformed when the door 3 is opened and closed.

At least one sealing rib may be provided at a lower portion of the body 130 . The sealing rib may block washing water flowing toward the blocking wall 233 by contacting the bottom surface 231 of the washing tub bottom 23 . That is, the body 130 is spaced apart from the bottom surface 231 , but the sealing rib contacts the bottom surface 231 to block the outflow of washing water.

In one embodiment, the sealing rib may include a plurality of ribs extending downward from the body 130 and contacting the bottom surface 231 of the washing tub bottom 23 .

For example, as shown in FIG. 9 , the sealing ribs include a first sealing rib 140 contacting the inner surface of the blocking wall 233 and a second sealing rib 140 spaced apart from the first sealing rib 140. A sealing rib 150 may be included.

The first sealing rib 140 may contact the bottom surface 231 by extending downward along the inner surface of the blocking wall 233 . Accordingly, the first sealing rib 140 can prevent washing water from riding over the barrier wall 233 .

The second sealing rib 150 extends downward from a position spaced apart from the first sealing rib 140, and at least one may be provided. At this time, the second sealing rib 150 may come into close contact with the bottom surface 231 due to its own load and the load of the body 130 . Therefore, the washing water blocking effect can be maximized.

The second sealing rib 150 may extend toward both side walls 237 of the washing tank bottom 23 and contact both side walls 237 respectively. Accordingly, the outflow of washing water through the space between the sealing part 100 and the side wall 237 may be blocked.

Meanwhile, a connection portion between the blocking wall 233 and the side wall 237 may be rounded to have a predetermined curvature. Accordingly, the edge of the second sealing rib 150 is also rounded to have a predetermined curvature, so that the blocking wall 233 and the side wall 237 can be in close contact with each other.

In one embodiment, at least one slit 151 may be formed in the second sealing rib 150 .

The second sealing rib 150 may block washing water flowing toward the blocking wall 233 . However, when a large amount of washing water flows into the bottom 23 of the washing tank, the washing water may flow between the first sealing rib 140 and the second sealing rib 150 . The slit 151 may prevent the washing water from accumulating between the sealing part 100 and the bottom surface 231 by discharging the washing water introduced between the first and second sealing ribs 140 and 150 to the rear.

In this case, the first sealing rib 140 extends toward both side walls 237 of the washing tank bottom 23, but is provided to cover at least the slit 151.

For example, as shown in FIG. 8 , the length L3 of the first sealing rib 140 may be greater than the distance L2 between the slits 151 . Accordingly, even if the washing water flowing toward the blocking wall 233 passes through the slit 151, the first sealing rib 140 blocks them to prevent the washing water from flowing out.

However, when the first sealing rib 140 extends to the side wall 237, it may be difficult to discharge the washing water through the discharge part 235. Therefore, the first sealing rib 140 should be formed shorter than the distance between both side walls 237 .

Meanwhile, if the door 3 is repeatedly opened and closed, the adhesion of the second sealing rib 150 to the bottom surface 231 may be weakened. To compensate for this, the sealing rib may further include a reinforcing rib 160 connecting the body 130 and the second sealing rib 150.

The reinforcing rib 160 is spaced apart from the second sealing rib 150 and extends downward from the body 130 , but may extend in a direction different from the extending direction of the second sealing rib 150 . Accordingly, the end of the reinforcing rib 160 may be connected to the second sealing rib 150 . In this case, the reinforcing rib 160 may improve adhesion between the second sealing rib 150 and the bottom surface 231 by pushing the second sealing rib 150 downward.

In one embodiment, as shown in FIG. 10 , the reinforcing rib 161 may cross the second sealing rib 150 and contact the bottom surface 231 . In this case, the reinforcing rib 161 may have an effect of preventing the second sealing rib 150 from falling from the bottom surface 231 as well as blocking washing water.

In one embodiment, the sealing rib may further include a third sealing rib 170 contacting the inner panel 31 . The third sealing rib 170 may prevent the washing water from leaking out through the space between the body 130 and the inner panel 31 .

Hereinafter, with reference to FIGS. 11 to 15, a coupling relationship between the washing tank bottom 23 and the sealing part 100 will be described in more detail.

FIG. 11 is a cross-sectional view taken along the line Ⅰ-Ⅰ′ of FIG. 4 . 12 is a cross-sectional view taken along line II-II′ of FIG. 4 . FIG. 13 is a cross-sectional view taken along line III-III' of FIG. 4 . FIG. 14 is a cross-sectional view taken along line IV-IV′ of FIG. 4 . FIG. 15 is a cross-sectional view taken along line V-V′ of FIG. 4 .

The first coupling part 110 is formed to surround the blocking wall 233 and may fix the sealing part 100 to the bottom 23 of the washing tub. A plurality of ribs are formed on the inner surface of the first coupling part 110 to prevent washing water from crossing the blocking wall 233 .

Meanwhile, the first coupling part 110 extends toward the side wall 237 and may be provided between the pair of discharge parts 235 . Accordingly, the length L1 of the first coupling part 110 (see FIG. 8 ) may be smaller than the gap D between the discharge parts 235 (see FIG. 6 ).

A drip tray 13 is provided under the discharge unit 235, and washing water overflowing through the discharge unit 235 may be guided into the base 4.

The second coupling part 120 is coupled to the inner panel 31 of the door 3 and can rotate together with the door 3 . At this time, since the second coupling part 120 is provided at a higher position than the first coupling part 110 , deformation of the body 130 can be minimized when the door 3 is opened.

The body 130 connects the first coupling portion 110 and the second coupling portion 120 and may extend up to the side wall 237 . At this time, the body 130 may have a downwardly convex shape and be spaced apart from the bottom surface 231 . Accordingly, when the door 3 is opened, the amount of deformation of the body 130 can be minimized.

The first sealing rib 140 may extend to the bottom surface 231 along the inner surface of the blocking wall 233 . At this time, a plurality of ribs may be further formed between the first sealing rib 140 and the blocking wall 233, and the washing water blocking effect may be maximized.

Meanwhile, the first sealing rib 140 extends toward the side wall 237 and is provided to cover at least the slit 151 . For example, as shown in FIG. 8 , the length L3 of the first sealing rib 140 may be greater than the distance L2 between the slits 151 .

The second sealing rib 150 extends downward from the body 130 to contact the bottom surface 231 and may extend laterally to the side wall 237 . Accordingly, the second sealing rib 150 may block washing water flowing toward the blocking wall 233 . In addition, a slit 151 is provided in the second sealing rib 150 so that washing water introduced between the first and second sealing ribs 140 and 150 can be discharged to the rear.

The reinforcing rib 160 may be spaced apart from the second sealing rib 150 and extend downward from the body 130 . In this case, since the reinforcing rib 160 extends in a direction different from the extending direction of the second sealing rib 150, the end of the reinforcing rib 160 may be connected to the second sealing rib 150. The reinforcing rib 160 may push the second sealing rib 150 downward to improve adhesion between the second sealing rib 150 and the bottom surface 231 .

The third sealing rib 170 extends from the body 130 toward the inner panel 31 and may shield a space between the body 130 and the inner panel 31 .

As described above, the washing water flowing toward the opened surface of the washing tub 2, that is, the blocking wall 233 is primarily blocked by the second sealing rib 150, and is blocked by the first sealing rib 140. may be blocked sequentially. In addition, it may be blocked three times by ribs formed on the inner surface of the first coupling part 110 . In addition, even if washing water flows in between the first sealing rib 140 and the second sealing rib 150, it can be removed through the slit 151 formed in the second sealing rib 150. Accordingly, the sealing part 100 can effectively prevent the washing water from leaking through the open surface of the washing tank 2 .
