[0039] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application.

[0040] The laundry treating device in the prior art comprises a water containing tub, a drain pipe and a drain pump, one end of the drain pipe is connected with a drain port at the bottom of the water containing tub, and the other end of the drain pipe is connected with the drain pump, and when the drain pump is started, the water in the water containing tub can be driven to be discharged through the drain pipe.

[0041] When the laundry treating device is washing laundry, the laundry to be washed is placed in the water containing tub, and the dissolution of washing powder needs a certain time, so the washing powder is easy to deposit at the bottom of the water containing tub, and when the water flow in the water containing tub rotates, the washing powder deposited at the bottom of the water containing tub is driven to rotate, at this time, the washing powder is easy to enter the drain pipe below the water containing tub, thereby reducing the utilization rate of the washing powder and affecting the washing effect.

[0042] Therefore, in the prior art, a blocking piece is arranged at the front end of the drain pipe and the drain port of the water containing tub, the blocking piece is used for opening and closing the drain port defined by the water containing tub, so as to reduce the washing powder entering the drain pipe when the water containing tub is washing laundry, reduce resource waste and reduce pollution. In this structure, a sealing chamber needs to be arranged at the front end of the drain pipe, one part of the sealing chamber is sealingly connected with the water containing tub, and the other part of the sealing chamber is connected with the drain pipe. In this case, the sealing structure is relatively complex, and the cost is relatively high. In addition, in some models which do not need to control the on-off connection between the drain pipe and the water containing tub, since the sealing chamber is not arranged, the connection between the drain pipe and the water containing tub needs to be changed, and the compatibility is low.

[0043] Hereinafter, a on-off assembly 100 according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0044] As shown in Figures 1-10 , the on-off assembly 100 according to the embodiment of the present application comprises a housing 10 and a blocking piece 20.

[0045] The housing 10 has a water passing cavity 103, a first water passing hole 101 and a second water passing hole 102, the first water passing hole 101 and the second water passing hole 102 are both in communication with the water passing cavity 103, the first water passing hole 101 is used for connecting the water containing tub 500 of the laundry treating device, and the second water passing hole 102 is used for connecting the drain pipe 61 of the laundry treating device, when the laundry treating device is draining, the water in the water containing tub 500 enters the water passing cavity 103 through the first water passing hole 101, enters the drain pipe 61 through the second water passing hole 102, and is discharged along the drain pipe 61.

[0046] The blocking piece 20 is movably arranged in the water passing cavity 103 under the action of buoyancy, and is used for opening and closing the first water passing hole 101, so as to control the on-off connection between the water passing cavity 103 and the water containing tub 500.

[0047] When the laundry in the water containing tub 500 is washed, the blocking piece 20 closes the first water passing hole 101, so as to reduce the washing powder entering the drain pipe 61, and thereby facilitate to improve the utilization rate of the washing powder in the water containing tub 500.

[0048] Specifically, when the laundry in the tub 500 is cleaned and the washing powder is added into the tub 500, the washing powder is prone to deposit at the bottom of the tub 500, and if there is no blocking member 20, when the water flow in the tub 500 rotates to clean the laundry, the washing powder at the bottom of the tub 500 is prone to fall into the drain pipe 61 and the water passing cavity 103, which results in low utilization rate of the washing powder and affects the cleaning effect on the laundry to be cleaned.

[0049] Therefore, by arranging the blocking member 20 to block the first water passing hole 101, when the water flow in the tub 500 rotates, the washing powder falling into the drain pipe 61 and the water passing cavity 103 is reduced, which facilitates to improve the utilization rate of the washing powder and the cleaning effect on the laundry to be cleaned.

[0050] It should be noted that when the laundry treating apparatus needs to clean the laundry and water is added into the tub 500, the drain pipe 61 is disconnected with the outside, and at this time, the drain pipe 61 is in a closed state, and the water can fill the drain pipe 61. Specifically, the water first enters the drain pipe 61 through the first water passing hole 101 and the second water passing hole 102, at this time, the water level in the water passing cavity 103 gradually rises, and the blocking member 20 is floated upward and closes the first water passing hole 101 under the action of the buoyancy, at this time, when water continues to be added into the tub 500, the water level in the tub 500 gradually rises to clean the laundry in the tub 500.

[0051] When the water in the tub 500 needs to be drained, the drain pipe 61 is connected with the outside, at this time, the water in the drain pipe 61 is drained, and at the same time, the water level in the water passing cavity 103 gradually decreases, and the blocking member 20 is floated downward with the water level in the water passing cavity 103, and the blocking member 20 opens the first water passing hole 101, and the water in the tub 500 enters the water passing cavity 103 through the first water passing hole 101, enters the drain pipe 61 from the second water passing hole 102, and is drained outward along the drain pipe 61.

[0052] In this way, the opening or closing of the first water passing hole 101 by the blocking member 20 is automatically realized when water is added and drained, and no additional control element is needed, which facilitates to reduce the complexity and save the cost.

[0053] In addition, the utility model discloses the on-off assembly 100 and drain pipe 61 are set apart, make the on-off assembly 100 itself as a structure, compared with the prior art plugging piece is arranged at the drain of the water tub, the water inlet of drain pipe, such structure needs to set up the sealing chamber of higher sealing property alone to accommodate plugging piece, and the sealing chamber is connected with drain pipe, such setting, not only the sealing property of sealing chamber and water tub is also higher, causes higher cost, in addition, in some models, the on-off of drain pipe and water tub is not needed, when drain pipe and water tub are directly connected, at this moment, another set of connecting structure and connecting mode are needed, and the compatibility is lower, causes the invisible increase of cost.

[0054] Meanwhile, the utility model discloses plugging piece 20 is arranged in shell 10, make the first water hole 101 of shell 10 is connected with water tub 500, and plugging piece 20 opens and closes the first water hole 101, like this, without considering the position of drain pipe 61 and the space in drain pipe 61, without changing any structure of drain pipe 61 or water tub 500, can realize the on-off between water tub 500 and drain pipe 61 by on-off assembly 100, and the cost is lower, and the compatibility is higher.

[0055] In addition, like this, also facilitate the first water hole 101 is set at the position of higher position, make the first water hole 101 and laundry treatment device's drain pump piece have enough distance, and then facilitate reducing the difficulty of drainage, to smoothly drain the water in water tub 500.

[0056] In some embodiments, when at least part of on-off assembly 100 is arranged in drain pipe 61, the on-off assembly 100 will not occupy any space at the bottom of the water tub 500.

[0057] Therefore, the on-off assembly 100 itself is a structure according to the utility model embodiment, the on-off assembly 100 is connected at the outlet of the water tub 500, without separately setting a sealing chamber, and without changing any structure of the drain pipe 61 or the water tub 500, the cost is lower, and the compatibility is higher.

[0058] In addition, the plugging piece 20 can be processed as a separate component, and then assembled with the drain port 51, which is simple to manufacture and low in cost.

[0059] The on-off assembly 100 according to the specific embodiments of the utility model will be described below with reference to the accompanying drawings.

[0060] In some specific embodiments of the utility model, as shown inFigures 1-10 As shown in the figure, the on-off assembly 100 comprises a shell 10 and a blocking piece 20.

[0061] In some embodiments of the utility model, as shown in the figure, Figure 4 As shown in the figure, the flow area of the first water passing hole 101 and the flow area of the second water passing hole 102 are all less than the maximum cross-sectional area of the blocking piece 20, so as to limit the floating range of the blocking piece 20.

[0062] Specifically, the flow area of the first water passing hole 101 is less than the maximum cross-sectional area of the blocking piece 20, so as to avoid the blocking piece 20 from entering the water tub 500, and the flow area of the second water passing hole 102 is less than the maximum cross-sectional area of the blocking piece 20, so as to avoid the blocking piece 20 from entering the drain pipe 61.

[0063] In some optional embodiments of the utility model, as shown in the figure, Figure 4 As shown in the figure, the first water passing hole 101 is a circular hole, and the blocking piece 20 is a sphere, so that the shape of the blocking piece 20 is matched with the shape of the first water passing hole 101, and then the blocking piece 20 can be attached to the hole wall of the first water passing hole 101, so as to fully block the first water passing hole 101.

[0064] In some embodiments of the utility model, as shown in the figure, Figures 7-10 As shown in the figure, the first water passing hole 101 is arranged on the top wall of the shell 10, and the at least one second water passing hole 102 is arranged on the bottom wall of the shell 10 and is oppositely arranged with the first water passing hole 101 in the up-down direction, so that when the water in the water tub 500 is discharged, the water entering from the first water passing hole 101 can smoothly flow to the second water passing hole 102, enter the drain pipe 61 from the second water passing hole 102, and be discharged along the drain pipe 61.

[0065] In some embodiments of the utility model, as shown in the figure, Figure 9 , Figure 10 As shown in the figure, the first water passing hole 101 is arranged on the top wall of the shell 10, and the number of the second water passing holes 102 is multiple, and at least a part of the second water passing holes 102 are arranged at intervals in the circumferential direction of the shell 10, so that when the water in the water tub 500 is discharged, the water entering from the first water passing hole 101 can smoothly flow to the second water passing hole 102, enter the drain pipe 61 from the second water passing hole 102, and be discharged along the drain pipe 61.

[0066] In some embodiments of the utility model, as shown in the figure, Figure 4 , Figure 7 and Figure 8As shown, the shell 10 also has a pressure relief backwater hole 151 for communicating the water tub 500 and the water passing cavity 103, so that after the water in the water tub 500 is discharged, the water passing cavity 103, the drain pipe 61 and the water tub 500 are communicated through the pressure relief backwater hole 151, and then the pressure in the water passing cavity 103 and the drain pipe 61 is atmospheric pressure, so that when the water flows back to the drain pipe 61, the pressure in the drain pipe 61 and the water passing cavity 103 is prevented from changing, and then the components for detecting the water level in the clothes treatment device are not disturbed.

[0067] Specifically, the clothes treatment device includes a structure defining an air chamber and a water level detection member, the air chamber is communicated with the drain pipe 61, and the water level detection member detects the water level in the water tub 500 according to the change of the air pressure of the air chamber. When water is added to the water tub 500, the gas in the air chamber is compressed, and when the water level in the water tub 500 gradually rises, the air pressure in the air chamber gradually increases, so that the water level in the water tub 500 is detected by detecting the change of the air pressure in the air chamber.

[0068] When the water in the water tub 500 is discharged, since the drain pipe 61 is not continuously extended downward, but is composed of multiple drain sections downward and upward, when the drain pump stops draining, the phenomenon of water flowing back to the water passing cavity 103 occurs. If there is no pressure relief backwater hole 151, the impact force of the air when the water flows back will make the blocking member 20 move upward, and the air pressure in the air chamber is compressed. At this time, although no water is added to the water tub 500, the air pressure in the air chamber suddenly increases for a period of time, and the detection structure of the water level detection member mistakenly thinks that water is being added to the water tub 500 at this time, which is inconsistent with the actual situation.

[0069] And the pressure relief backwater hole 151 is provided, and when the water flows back, since the drain pipe 61 is communicated with the outside atmosphere through the pressure relief backwater hole 151, the air pressure in the drain pipe 61 will not change at this time, and the air pressure in the air chamber will not change or change little, so that the detection result of the water level detection member is consistent with the actual situation.

[0070] The pressure relief backwater hole 151 is higher than the first water passing hole 101, so that the washing powder is not easy to accumulate at the pressure relief backwater hole 151. Specifically, when the washing powder falls to the bottom of the water tub 500 and the water flow in the water tub 500 rotates, the washing powder is not easy to enter the pressure relief backwater hole 151 which is located higher, and then the washing powder entering the water passing cavity 103 and the drain pipe 61 from the pressure relief backwater hole 151 can be reduced, so as to improve the utilization rate of the washing powder.

[0071] In some embodiments, the drain pipe 61 is a three-way pipe, one end of the drain pipe 61 is connected with the drain pump of the clothes treatment device, one end is connected with the drain port of the water tub, and one end is connected with the air chamber.

[0072] In some optional embodiments of the present application, as shown inFigure 7 , Figure 8 As shown, there are multiple pressure relief return water holes 151, which are arranged circumferentially around the first water passage hole 101. After the water in the water tank 500 is discharged, the multiple pressure relief return water holes 151 connect the outside atmosphere, the water passage cavity 103, and the drain pipe 61. In this way, when water flows back, the multiple pressure relief return water holes 151 keep the pressure in the drain pipe 61 and the water passage cavity 103 unchanged or very small, thereby avoiding interference with the water level detection components in the clothing processing device.

[0073] In some optional embodiments of this utility model, such as Figure 4 , Figure 7 As shown, the top wall of the outer casing 10 has an upwardly extending mounting protrusion 15. The top wall of the mounting protrusion 15 is higher than the first water passage hole 101. The pressure relief return hole 151 is provided on the top wall of the mounting protrusion 15. By setting the pressure relief return hole 151 at a higher position, when the water in the water tank 500 rotates, the laundry detergent is less likely to remain on the mounting protrusion 15, thereby reducing the amount of laundry detergent entering the drain pipe 61 through the pressure relief return hole 151 and improving the utilization rate of the laundry detergent.

[0074] In some embodiments, such as Figure 1 , Figure 4 As shown, the bottom of the water tank 500 has a recess 52 that is recessed outward along the radial direction of the water tank 500. The drain outlet 51 is located on the bottom wall of the recess 52 so that the water in the water tank 500 can be smoothly discharged from the drain outlet 51. The pressure relief return hole 151 is higher than the bottom wall of the recess 52, so the laundry detergent is easy to accumulate on the bottom wall of the recess 52, but difficult to accumulate at the pressure relief return hole 151. This makes it easier to reduce the amount of laundry detergent entering the drain pipe 61 from the pressure relief return hole 151, thereby improving the utilization rate of the laundry detergent.

[0075] Specifically, when the water in the water tank 500 rotates, it can move the laundry detergent accumulated on the bottom wall of the recess 52 to dissolve the laundry detergent, so that the pressure relief return hole 151 is higher than the bottom wall of the recess 52, so that the laundry detergent is less likely to accumulate at the pressure relief return hole 151, thereby reducing the amount of laundry detergent entering the drain pipe 61 from the pressure relief return hole 151, and improving the utilization rate of the laundry detergent.

[0076] In some specific embodiments of this utility model, such as Figure 7 As shown, the mounting protrusion 15 extends circumferentially along the first water passage 101, and the top wall of the mounting protrusion 15 is provided with a pressure relief return water hole 151.

[0077] In other specific embodiments of this utility model, such as Figure 7As shown, the top wall of the mounting protrusion 15 is provided with a plurality of pressure relief backwater holes 151, and the plurality of pressure relief backwater holes 151 are arranged in the extension direction of the mounting protrusion 15, so as to reasonably arrange the positions of the plurality of pressure relief backwater holes 151, so as to avoid that the hole diameter of the pressure relief backwater hole 151 is too large while ensuring the pressure relief area, thereby being capable of reducing the washing powder entering the water cavity 103 and the drain pipe 61 through the pressure relief backwater hole 151.

[0078] In some optional embodiments of the present application, as shown in Figure 7 As shown, the number of the mounting protrusions 15 is multiple, the plurality of mounting protrusions 15 are arranged in the circumferential direction of the first water passing hole 101, and the water passing channel 16 is arranged between the adjacent two mounting protrusions 15, so as to allow the water flow, so that the liquid remaining at the bottom of the water tub 500 can flow to the first water passing hole 101 through the water passing channel 16, thereby avoiding that too much water remains at the bottom of the water tub 500, and avoiding that the water remaining for a long time will produce odor or breed bacteria.

[0079] In some embodiments of the present application, as shown in Figures 6-10 As shown, the shell 10 comprises a first shell 11 and a second shell 12, the first shell 11 is arranged above the second shell 12, the first water passing hole 101 is arranged in the first shell 11, and the second water passing hole 102 is arranged in the second shell 12, so as to be capable of placing the plugging part in the shell 10, and the plugging part 20 is capable of opening and closing the first water passing hole 101.

[0080] In some examples, the upper end of the first shell 11 defines the first water passing hole 101, the lower end of the second shell 12 defines the second water passing hole 102, the flow area of the first water passing hole 101 and the second water passing hole 102 is smaller than the maximum cross-sectional area of the plugging part 20, the first shell 11 and the second shell 12 are in a split structure, so as to be capable of loading the plugging part 20 into the water cavity 103 from the lower end of the first shell 11 and the upper end of the second shell 12, and the plugging part 20 is capable of floating with the water level in the water cavity 103.

[0081] In some optional embodiments of the present application, as shown in Figure 10 As shown, the second shell 12 comprises a shell body 121 and a connecting ring 122, the second water passing hole 102 is arranged in the shell body 121, the connecting ring 122 is connected above the shell body 121 and extends along the circumferential direction of the shell body 121, and the second shell 12 is connected with the first shell 11 through the connecting ring 122, so as to fixedly connect the second shell 12 and the first shell 11 together.

[0082] In some specific embodiments of the present application, as shown in Figure 10As shown, the sealing element 20 is a sphere, and the inner surface of the shell body 121 is a spherical surface. The radial dimension of the spherical surface is larger than the radial dimension of the sphere, so that when the sealing element 20 abuts against the inner surface of the shell body 121, the sealing element 20 can be prevented from completely blocking the second water passage hole 102, thereby avoiding affecting the drainage of the water tank 500.

[0083] Specifically, when the water in the water tank 500 is drained, the drain pipe 61 is connected to the outside. At this time, the water in the drain pipe 61 is drained, and the water level in the water passage cavity 103 gradually decreases. The sealing member 20 floats down with the water level in the water passage cavity 103 to a position where it abuts against the shell body 121, so that the inner surface of the shell body 121 is a spherical surface. The radial dimension of the spherical surface is larger than the radial dimension of the sphere. When part of the sealing member 20 abuts against the inner wall of the spherical surface, the sealing member 20 cannot completely block the second water passage hole 102. At least part of the second water passage hole 102 is connected to the water passage cavity 103 and the drain pipe 61, so that water can enter the drain pipe 61 from the second water passage hole 102 and be discharged outward along the drain pipe 61.

[0084] In some specific embodiments of this utility model, the first housing 11 is sleeved on the outside of the connecting ring 122.

[0085] like Figure 10 As shown, in this embodiment, the first housing 11 is fitted over the second housing 12, and the outer peripheral wall of the connecting ring 122 is engaged with the inner peripheral wall of the first housing 11. That is, at least a portion of the first housing 11 and the connecting ring 122 are directly opposite each other. This facilitates the formation of a bent gap between the first housing 11 and the second housing 12. Compared to forming a straight gap between the first housing 11 and the second housing 12, forming a bent gap between the first housing 11 and the second housing 12 can reduce the possibility of water in the water passage cavity 103 flowing out through the gap between the first housing 11 and the second housing 12.

[0086] In some embodiments, such as Figure 10 As shown, the inner surface of the first housing 11 has a limiting step 111, which stops above the connecting ring 122 to limit the position of the connecting ring 122 when it is assembled.

[0087] Specifically, when the connecting ring 122 moves upward and its upper end stops at the limiting step 111, the connecting ring 122 is in position. The limiting step 111 can restrict the upward movement of the connecting ring 122, thereby limiting the position of the connecting ring 122.

[0088] The following describes a clothing processing device according to an embodiment of the present invention. The clothing processing device according to an embodiment of the present invention includes a water tank 500, a drainage assembly, and an on / off assembly 100 according to the above embodiment of the present invention.

[0089] The bottom of the water tub 500 has a drain port 51, and a drain assembly includes a drain pipe 61 and a drain pump, the drain pipe 61 is connected with the drain pump and the drain port 51, and the assembly is detachably arranged at the connection between the drain port 51 and the drain pipe 61, so as to control the connection between the water tub 500 and the drain pipe 61 by controlling the connection between the water passage cavity 103 and the water tub 500.

[0090] The drain assembly 100 is detachably arranged between the drain port 51 and the drain pipe 61, which facilitates the installation and disassembly of the drain assembly 100, and further facilitates the replacement and maintenance of the drain assembly 100.

[0091] Specifically, when the drain pump drives the water in the water tub 500 to be discharged outward, the drain pipe 61 is in communication with the outside, at this time, the water in the drain pipe 61 is discharged, and the water level in the water passage cavity 103 gradually decreases, the blocking piece 20 floats downward with the water level in the water passage cavity 103, the blocking piece 20 opens the first water passage hole 101, and the water in the water tub 500 enters the water passage cavity 103 through the first water passage hole 101, enters the drain pipe 61 through the second water passage hole 102, and is discharged outward along the drain pipe 61.

[0092] When the drain pump stops working, the drain pipe 61 is in a closed state, and when water is added to the water tub 500, the water can fill the drain pipe 61, specifically, the water first enters the drain pipe 61 through the first water passage hole 101 and the second water passage hole 102, at this time, the water level in the water passage cavity 103 gradually rises, and the blocking piece 20 floats upward and closes the first water passage hole 101 under the action of the buoyancy, at this time, when water continues to be added to the water tub 500, the water level in the water tub 500 gradually rises.

[0093] By arranging the blocking piece 20, the blocking piece 20 can block the first water passage hole 101, so that when the water in the water tub 500 flows, the amount of washing powder falling into the drain pipe 61 and the water passage cavity 103 can be reduced, thereby facilitating the utilization rate of the washing powder and improving the cleaning effect on the clothes to be cleaned.

[0094] According to the clothes processing device, the drain assembly 100 is used, the drain assembly 100 is a structure, a sealing chamber does not need to be arranged, and any structure of the drain pipe 61 or the water tub 500 does not need to be changed, so that the cost is low and the compatibility is high.

[0095] In addition, the application sets the blocking piece 20 as a structure, which can be processed as a separate component, assembled with the drain 51, simple in manufacture, low in cost, and occupying no space of the bottom of the water tub 500, thereby saving space.

[0096] In some embodiments of the application, the bottom of the water tub 500 is provided with a pipe joint 53, the pipe joint 53 is arranged around the drain 51, and the drain pipe 61 is sleeved on the pipe joint 53 and fixedly connected with the pipe joint 53.

[0097] The drain pipe 61 defines a water inlet cavity 611, and the lower part of the shell 10 extends into the water inlet cavity 611, and the second water passing hole 102 at the lower end of the shell 10 is in communication with the water inlet cavity 611.

[0098] In some embodiments, the shell 10 includes a first shell 11 and a second shell 12, the first shell 11 is arranged above the second shell 12, the first water passing hole 101 is arranged at the upper end of the first shell 11, the second water passing hole 102 is arranged at the lower end of the second shell 12, the first shell 11 defines a mounting protrusion 15, the mounting protrusion 15 extends into the water tub 500 from the drain 51 and is higher than the bottom of the water tub 500, and the mounting protrusion 15 is provided with a pressure relief backwater hole 151.

[0099] The pressure relief backwater hole 151 is in communication with the water tub 500 and the water passing cavity 103, so that the water passing cavity 103, the drain pipe 61 and the water tub 500 are communicated through the pressure relief backwater hole 151 after the water in the water tub 500 is discharged, and the pressure in the water passing cavity 103 and the drain pipe 61 is atmospheric pressure.

[0100] The second shell 12 is located in the water inlet cavity 611, and the second water passing hole 102 is spaced from the cavity wall of the water inlet cavity 611 to communicate the drain pipe 61 and the water passing cavity 103, so that the water in the water passing cavity 103 can enter the drain pipe 61 through the second water passing hole 102.

[0101] In some embodiments, as Figure 4As shown, the outer periphery of the housing 10 has a positioning step 18, and the edge of the drain outlet 51 is stopped above the positioning step 18 to limit the relative position of the housing 10 and the water tank 500, so as to prevent the entire housing 10 of the switch assembly 100 from entering the water tank 500.

[0102] The drain pipe 61 defines the water inlet cavity 611, the second housing 12 extends into the water inlet cavity 611, and the first housing 11 extends into the water tank 500, so that the edge of the drain outlet 51 is stopped above the positioning step 18 to limit the relative position of the outer shell 10 and prevent the outer shell 10 from entering the water tank 500 completely.

[0103] In some embodiments, such as Figure 4 As shown, the outer periphery of the outer casing 10 is provided with a support protrusion 17, which surrounds the outer periphery of the outer casing 10 and supports the inner wall surface of the drain pipe 61 to limit the relative position of the outer casing 10 and the drain pipe 61, so that the second water passage hole 102 avoids the inner wall surface of the drain pipe 61, and prevents the inner wall of the drain pipe 61 from blocking the second water passage hole 102, so that the water in the water tank 500 can smoothly enter the drain pipe 61 through the first water passage hole 101 and the second water passage hole 102.
