Description

Technical Field

[0001] This application relates to the technical field of clothes drying, and particularly to a clothes dryer and its base assembly. Background Art

[0002] In the related art, a clothes dryer includes a drying drum, a heat exchange component, a filter screen, and a base located below the drying drum. An air duct and a lint chamber communicating with the air duct are formed inside the base. The heat exchange component is arranged in the air duct, and the filter screen is arranged in the lint chamber. The heat exchange component forms dry hot air flow, and the dry hot air flow enters the drying drum through the air duct. The dry hot air flow contacts the wet clothes in the drying drum and is converted into wet cold air flow carrying lint. The wet cold air flow carrying lint enters the lint chamber, flows through the filter screen to remove lint and forms filtered wet cold air flow. The filtered wet cold air flow contacts the heat exchange component again for heat exchange to form dry hot air flow, and the dry hot air flow returns to the drying drum again and exchanges heat with the wet clothes in the drying drum to form wet cold air flow again. Such a cycle is repeated to dry the clothes.

[0003] During the air flow process, lint is likely to adhere to the inner side wall of the filter screen and the lint chamber, and it is difficult for the lint to fall off from the inner side wall of the filter screen and the lint chamber. Usually, users need to work on the ground, and use hands or other objects to stir the lint adhering to the inner side wall of the filter screen and the lint chamber to clean the inner side wall of the filter screen and the lint chamber. In this way, the comfort level during the operation process is low, and it is difficult to thoroughly clean the lint adhering to the inner side wall of the filter screen and the lint chamber.

[0040] It should be noted that, without conflict, the embodiments in the present application and the technical features in the embodiments can be combined with each other. The detailed description in the detailed implementation manners should be understood as an explanatory illustration of the gist of the present application and should not be regarded as an improper limitation to the present application.

[0041] In the description of the embodiments of the present application, the orientation or positional relationship of "upper", "lower", "top", "bottom", "front", "rear", "left", "right" is the orientation or positional relationship when the base assembly is in normal use. For example, Figure 1 and Figure 2 the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0042] Please refer to Figures 1 to 6 Figures 1 to 6 , an embodiment of the present application provides a base assembly for a dryer. The base assembly includes a base 100 and a filtering device 200. A lint chamber 100a is formed in the base 100. The filtering device 200 includes a stop block 230 and a filter element 220 having a ventilation air duct 220a. The filter element 220 is rotatably disposed in the lint chamber 100a. The stop block 230 is disposed in the lint chamber 100a, and the stop block 230 blocks the lint that is centrifugally separated from the filter element 220.

[0043] In the base assembly provided by the embodiment of the present application, the wet and cold air flow carrying lint enters the lint chamber 100a. After being filtered by the filter element 220, the wet and cold air flow becomes the wet and cold air flow from which lint is removed. The wet and cold air flow from which lint is removed is discharged from the lint chamber 100a through the ventilation air duct 220a. In this way, the lint is collected in the lint chamber 100a, and the filtered wet and cold air flow is blown out of the lint chamber 100a through the ventilation air duct 220a, achieving the purpose of filtering the air flow. On the one hand, the lint adhering to the outer surface of the filter element 220 can be removed by rotating the filter element 220, so that the lint is separated from the filter element 220 under the action of centrifugal force. In this way, the lint is centrifugally separated from the filter element 220 under the action of centrifugal force, realizing self-cleaning of the filter element 220. The user does not need to manually clean the filter element 220, and the user experience is good. On the other hand, the base 100 forms a lint chamber 100a, and the filtered air flow is discharged from the lint chamber 100a through the ventilation air duct 220a. The structure is simple and structural components are saved; the stop block 230 is used to block the lint that is centrifugally separated from the filter element 220, avoiding the lint that is centrifugally separated from the filter element 220 being thrown onto the inner side wall of the lint chamber 100a, and to a certain extent, avoiding the user from crouching on the ground to clean the inner side wall of the lint chamber 100a.

[0044] The base assembly is used for a dryer. The dryer provided by the embodiment of the present application includes a drying drum and the base assembly in any embodiment of the present application. The drying drum has a drying chamber. The base assembly is located below the drying drum, and the lint chamber 100a is communicated with the drying chamber. The drying chamber is used for placing clothes to be processed, such as wet clothes to be dried. The wet and cold air flow carrying lint from the drying drum enters the lint chamber 100a. After being filtered by the filter element 220, it is then discharged from the lint chamber 100a through the ventilation air duct 220a. The separated lint can be temporarily stored in the lint chamber 100a. The layout between the drying drum and the base assembly is compact, and the occupied installation space is small.

[0045] The clothes drying drum can rotate. Exemplarily, in one embodiment, the rotation axis of the clothes drying drum is in the front-to-back direction, and the front side of the clothes drying drum has a delivery port connected to the clothes drying chamber, and the user can deliver clothes into or take out of the clothes drying chamber through the delivery port. In the clothes drying mode, the clothes drying drum can rotate continuously. During the rotation of the clothes drying drum, the clothes drying drum drives the clothes in the clothes drying chamber to move, and the clothes constantly change their posture during the movement so as to fully contact with the dry hot air flow, thereby improving the clothes drying efficiency.

[0046] In one embodiment, please refer to Figure 3 and Figure 4 The lint chamber 100a has an air inlet 100aa and an air outlet 100ab. The wet and cold airflow carrying lint enters the lint chamber 100a from the air inlet 100aa, and the wet and cold airflow carrying lint is filtered by the filter element 220 to become a wet and cold airflow with lint removed, and the wet and cold airflow with lint removed is blown toward the air outlet 100ab through the ventilation duct 220a, so that the lint is collected in the lint chamber 100a, and the filtered wet and cold airflow is blown out of the lint chamber 100a through the air outlet 100ab, thereby achieving the purpose of filtering the airflow.

[0047] In one embodiment, the clothes dryer includes a heat exchange component, a heat exchange air duct is formed on the base 100, the heat exchange air duct is connected to the clothes drying chamber and the air outlet 100ab, and the heat exchange component is arranged in the heat exchange air duct. The heat exchange component is used to convert the filtered wet cold airflow from the air outlet 100ab into a dry hot airflow, and the dry hot airflow then flows back into the clothes drying chamber. In other words, the clothes dryer is a heat pump clothes dryer, which dries clothes through circulating airflow, and the user experience is good.

[0048] In one embodiment, the heat exchange assembly includes an evaporator and a condenser, the heat exchange air duct is located behind the dander chamber 100a, the evaporator and the condenser are both located in the heat exchange air duct, and the evaporator is located in front of the condenser. For example, the evaporator and the condenser can both be fin-tube heat exchangers, and the refrigerant flows in the evaporator and the condenser to exchange heat with the wet and cold airflow flowing through the heat exchange air duct. On the flow path of the airflow, the airflow first flows through the evaporator and then through the condenser. For example, the wet and cold airflow from the air outlet 100ab enters the heat exchange air duct from the front side, first flows through the evaporator and then flows through the condenser. The wet and cold airflow from the air outlet 100ab exchanges heat with the evaporator for dehumidification to form a dry and cold airflow, which is heated by the condenser to form a dry and hot airflow, which flows back into the drying chamber, and the dry and hot airflow exchanges heat with the wet clothes in the drying chamber again to form a wet and cold airflow.

[0049] It should be noted that in the embodiment of the present application, the front side refers to the side facing the user, and the rear side, which is opposite to the front side, refers to the side facing away from the user. The top side refers to the side where the ceiling is located, and the bottom side refers to the side where the ground is located.

[0050] In one embodiment, please refer to Figures 2 to 4, the rotation axis of the filter element 220 is arranged in the front-rear direction. An air inlet 100aa is formed on the upper surface of the lint chamber 100a, and an air outlet 100ab is formed on the rear side surface of the lint chamber 100a. That is to say, the air flow carrying lint from the drying chamber enters the lint chamber 100a from the upper side of the base 100 and then enters the heat exchange air duct from the rear side. With such a design, on the one hand, the distance between the air inlet 100aa and the drying chamber is relatively close, and the air flow path between the air inlet 100aa and the drying chamber can be shorter, so that the wet and cold air flow carrying lint in the drying chamber can smoothly enter the air inlet 100aa, and the air resistance is small. On the other hand, the distance between the air outlet 100ab and the heat exchange air duct is relatively close, so that the wet and cold air flow with lint removed can smoothly enter the heat exchange air duct, and the air loss is small.

[0051] In one embodiment, please refer to Figure 1 and Figure 3 , the stopper 230 is arranged in the up-down direction. During the rotation of the filter element 220, the centrifugally separated lint is thrown out along the tangential direction of the circumference of the filter element 220. The stopper 230 is arranged in the up-down direction to ensure that the centrifugally separated lint all impacts on the stopper 230.

[0052] In one embodiment, please refer to Figure 1 and Figure 3 , the stopper 230 is located on the left side of the filter element 220, and the air inlet 100aa extends from above the filter element 220 to the right side of the filter element 220. Specifically, in the front-to-back projection (taking Figure 3For reference), the filter element 220 rotates in the clockwise direction. The airflow from the air inlet 100aa blows towards the filter element 220 from directly above and the upper right of the filter element 220. On the one hand, the airflow can blow the lint adhering to the left and right sides of the filter element 220 down to the bottom surface of the lint chamber 100a, and the lint is not easily adhered to the left side surface of the lint chamber 100a. On the other hand, the airflow can blow the lint adhering to the upper surface of the filter element 220 down to the bottom surface of the lint chamber 100a. In addition, during the rotation of the filter element 220, the upper surface of the filter element 220 rotates from top to bottom, and the lint adhering to the upper surface of the filter element 220 moves centrifugally from top to bottom under the action of centrifugal force, and the lint adhering to the upper surface of the filter element 220 can be thrown off to the bottom surface of the lint chamber 100a. In this way, the lint is not easily adhered to the left side surface of the lint chamber 100a. On the other hand, the lower surface of the filter element 220 is the leeward surface but close to the bottom surface of the lint chamber 100a, and lint may adhere to it. The lint adhering to the lower part of the filter element 220 is difficult to contact the airflow. Therefore, the lint adhering to the lower part of the filter element 220 is mainly removed by centrifugal throwing. The lint adhering to the lower part of the filter element 220 moves from bottom to top under the action of centrifugal force and is easily thrown off to the left side surface of the lint chamber 100a. Therefore, a stop block 230 is provided on the left side of the filter element 220 to block the lint, to a certain extent, to prevent the lint from adhering to the left side surface of the lint chamber 100a.

[0053] It should be noted that in the embodiments of the present application, the left-right direction, the up-down direction, and the front-back direction are perpendicular to each other and jointly form a three-dimensional vertical coordinate system. The top side is consistent with the upper direction, and the bottom side is consistent with the lower direction.

[0054] In one embodiment, please refer to Figure 3 , the upper part of the stop block 230 bends towards the side where the filter element 220 is located. For example, the upper part of the stop block 230 bends to the right. In this way, when the lint adhering to the lower part of the filter element 220 is thrown off under the action of centrifugal force, and the thrown-off lint moves centrifugally from bottom to top, the upper part of the stop block 230 can more comprehensively block the thrown-off lint, so that the lint directly falls to the bottom surface of the lint chamber 100a after being blocked by the upper part of the stop block 230.

[0055] In one embodiment, please refer to Figure 3 , the surface of the stop block 230 facing the filter element 220 is a smooth arc surface. For example, the right side surface 230a of the stop block 230 is a smooth arc surface. With such a design, the lint thrown off to the stop block 230 can slide down along the arc surface or fall directly.

[0056] In one embodiment, please refer to Figure 3, the lowest position D1 of the stopper 230 is lower than or flush with the lowest position L1 of the filter element 220. After the lint adhered to the lowest position L1 of the filter element 220 is thrown off, it moves towards the stopper 230 along the tangent direction of the lowest position L1 of the filter element 220. Since the lowest position D1 of the stopper 230 is lower than or flush with the lowest position L1 of the filter element 220, in this way, the lint moving towards the stopper 230 along the tangent of the lowest position L1 of the filter element 220 can be thrown off onto the stopper 230, preventing the thrown-off lint from remaining on the left side surface of the lint chamber 100a.

[0057] In one embodiment, please refer to Figure 3 , the highest position D2 of the stopper 230 is flush with or higher than the highest position L2 of the filter element 220. In this way, the stopper 230 has a relatively high height and can block the lint moving upward in a centrifugal motion as much as possible.

[0058] In one embodiment, please refer to Figure 3 and Figure 4 , the base assembly includes a spray head 300. The spray head 300 includes a nozzle 310 located in the lint chamber 100a. The nozzle 310 can spray water onto the outer surface of the filter element 220. The water flow sprayed by the nozzle 310 flushes the outer surface of the filter element 220, so that the lint on the outer surface of the filter element 220 is impacted and separated by the water flow. In this way, the cleaning efficiency and cleaning effect are further improved.

[0059] In one embodiment, please refer to Figure 3 and Figure 4, the number of nozzles 310 is multiple. The nozzle 310 located on the left side of the filter element 220 is the first nozzle 311, and the nozzle 310 located on the right side of the filter element 220 is the second nozzle 312. Both the first nozzle 311 and the second nozzle 312 are not lower than the filter element 220. The first nozzle 311 sprays water to the right, and the second nozzle 312 sprays water downward. The multiple nozzles 310 are divided into the first nozzle 311 or the second nozzle 312. The first nozzle 311 is located on the left side of the filter element 220, and the second nozzle 312 is located on the right side of the filter element 220. The lowest positions of the first nozzle 311 and the second nozzle 312 are both flush with or higher than the highest position of the filter element 220. The first nozzle 311 sprays water to the right towards the filter element 220, and the water flow sprayed by the first nozzle 311 flushes the upper surface of the filter element 220. The second nozzle 312 sprays water downward towards the filter element 220 from top to bottom, and the water flow sprayed by the second nozzle 312 flushes the right side surface of the filter element 220. The upper surface of the filter element 220 and the right side surface of the filter element 220 are windward surfaces. Although the lint adhered to the upper surface of the filter element 220 and the right side surface of the filter element 220 can be blown down by the airflow, compared with other surfaces of the filter element 220, the upper surface of the filter element 220 and the right side surface of the filter element 220 have a larger contact area with the airflow, and the upper surface of the filter element 220 and the right side surface of the filter element 220 may still adhere to lint. Therefore, in addition to using the rotation of the filter element 220 to centrifugally separate the lint, the upper surface of the filter element 220 can be flushed by the first nozzle 311, and the right side surface of the filter element 220 can be flushed by the second nozzle 312. In this way, the lint on the upper surface of the filter element 220 and the right side surface of the filter element 220 can be removed targeted.

[0060] The specific structure of the spray head 300 is not limited. Exemplarily, in one embodiment, please refer to Figure 3 and Figure 4 , the spray head 300 includes a water guiding body 320 and two water supply pipes 330. The water guiding body 320 is arranged in the left-right direction, and the water supply pipes 330 are arranged in the front-back direction. The two water supply pipes 330 are respectively located on the left and right sides of the water guiding body 320 and are both communicated with the water guiding body 320. At least one nozzle 310 is arranged on each of the two water supply pipes 330. An inlet 320a is formed on the water guiding body 320. For example, the first nozzle 311 is located on the left water supply pipe 330, and the second nozzle 312 is located on the right water supply pipe 330. The water flow enters the water guiding body 320 through the inlet 320a. The water guiding body 320 guides the water flow to the two water supply pipes 330, and then sprays out from the nozzles 310. Designed in this way, the structure of the spray head 300 is simple. The water supply pipes 330 are arranged in the front-back direction, and the water supply pipes 330 are respectively arranged on the left and right sides of the water guiding body 320. In this way, the nozzles 310 can cover as many areas as possible in the front-back direction of the filter element 220.

[0061] It should be noted that, in the embodiments of the present application, a plurality refers to a number of two or more.

[0062] The number of nozzles 310 is not limited. For example, in one embodiment, please refer to Figure 4 There are three nozzles 310 in total, including one first nozzle 311 and two second nozzles 312 .

[0063] The specific structure of the nozzle 310 is not limited. For example, in one embodiment, the water supply pipe 330 is formed with a water supply hole, and the nozzle 310 includes two guide plates, which are located on opposite sides of the water supply hole, and the two guide plates jointly define a water outlet. With such a design, on the one hand, the direction of the water flow sprayed out of the water outlet can be changed by changing the direction of the guide plates, and the structure is simple. On the other hand, the guide plates can be in the shape of long strips, and the two long strips of guide plates can define a long strip of water outlet. In this way, the water flow sprayed out from the water outlet is in the shape of a flat waterfall, the water flow rate is fast and the coverage area is large, and the filter element 220 can be more fully rinsed.

[0064] The condensed water of the clothes dryer can be used to supply water to the nozzle 300. In one embodiment, the clothes dryer includes a condensed water pan and a condensed water pump. The condensed water pan is located at the bottom of the heat exchange component and is used to receive the condensed water from the heat exchange component. The condensed water pump pumps the condensed water in the condensed water pan to the water inlet 320a. In other words, the condensed water is used as a water source for washing the filter element 220, so as to realize the secondary utilization of the condensed water and save energy and protect the environment.

[0065] Tap water can also be used to supply water to the nozzle 300. In one embodiment, the clothes dryer includes a water supply pipe and a water supply pump. The water supply pipe connects the tap water pipe and the water inlet 320a. The water supply pump pumps the tap water into the water inlet 320a. In this way, tap water is used as a water source for washing the filter 220.

[0066] In one embodiment, please refer to Figure 1 , Figure 5 and Figure 6 The filter device 200 includes a driving member 210, which is connected to the filter element 220 to drive the filter element 220 to rotate. The driving member 210 provides power to drive the filter element 220 to rotate, so that during the rotation of the filter element 220, the hair debris adhering to the outer surface of the filter element 220 is centrifugally separated.

[0067] In one embodiment, please refer to Figure 1 , Figure 5 and Figure 6, the filtering device 200 includes a mounting frame 240 detachably connected to the base 100. The filtering element 220 is rotatably arranged on the mounting frame 240, and the stopper 230 is fixed on the mounting frame 240. On the one hand, the stopper 230, the filtering element 220 and the mounting frame 240 form a module. The stopper 230 and the filtering element 220 can be assembled to the mounting frame 240 first, and then the mounting frame 240 can be assembled to the base 100, which reduces the assembly difficulty and improves the assembly efficiency.

Another example is that if the connecting block 242 is formed with a positioning hole 243c, then the rear cover 243 is formed with a positioning post 2421. When assembling the rear cover 243 to the connecting block 242, the positioning post 2421 is first inserted into the positioning hole 243c to achieve the positioning function, and then the screw is tightened into the first screw hole 242a and the second screw hole 243b. In this way, the misalignment between the rear cover 243 and the connecting block 242 can be avoided, and the assembly difficulty can be reduced.

[0077] In one embodiment, please refer to Figure 5 and Figure 6 , the stop block 230 and the rear cover 243 are connected by screws. For example, the stop block 230 is formed with a third screw hole 230b, and the rear cover 243 is formed with a fourth screw hole 243d. The screw passes through the third screw hole 230b and the fourth screw hole 243d to fix the rear cover 243 and the stop block 230 into one body.

[0078] In one embodiment, one of the stop block 230 and the rear cover 243 is formed with an insertion bar 231, and the other of the stop block 230 and the rear cover 243 is formed with an insertion hole 243e. The insertion bar 231 can be inserted into the insertion hole 243e. For example, please refer to Figure 5 and Figure 6 , if the stop block 230 is formed with an insertion bar 231, then the rear cover 243 is formed with an insertion hole 243e. Another example is that if the stop block 230 is formed with an insertion hole 243e, then the rear cover 243 is formed with an insertion bar 231. The insertion bar 231 is first inserted into the insertion hole 243e to achieve the positioning function, and then the screw is tightened into the third screw hole 230b and the fourth screw hole 243d. In this way, it is convenient for the stop block 230 and the rear cover 243 to be quickly aligned, the misalignment between the stop block 230 and the rear cover 243 can be avoided, and the assembly difficulty can be reduced.

[0079] In one embodiment, please refer to Figure 3 and Figure 6, the number of the connecting blocks 242 can be two. Both of the two connecting blocks 242 are located on the right side of the filter element 220, and the two connecting blocks 242 are distributed at intervals up and down. In this way, the stop block 230 and the two connecting blocks 242 are roughly triangularly distributed, and the force bearing is better.

[0080] The specific manner of the detachable connection between the mounting frame 240 and the base 100 is not limited. For example, the mounting frame 240 and the base 100 are connected by screws. In one embodiment, please refer to Figure 1 and Figure 5 , one of the front cover 241 and the base 100 is formed with a mounting hole 241b, and the other of the front cover 241 and the base 100 is formed with a stud 110. The stud 110 passes through the mounting hole 241b, and the screw is in threaded cooperation with the stud 110 to fix the filtering device 200 to the base 100.

[0081] In one embodiment, the outer peripheral edge of the front cover 241 is in sealing cooperation with the surrounding part of the mounting opening 100ac, and the outer peripheral edge of the rear cover 243 is in sealing cooperation with the surrounding part of the air outlet 100ab. In this way. The gap between the outer peripheral edge of the front cover 241 and the surrounding part of the mounting opening 100ac will not leak air, and the gap between the outer peripheral edge of the rear cover 243 and the surrounding part of the air outlet 100ab will not leak air either. The airtightness between the filtering device 200 and the base 100 is good. The air flow from the air inlet 100aa is filtered by the filter element 220 and then flows out through the ventilation air duct 220a from the ventilation opening 243a.

[0082] In one embodiment, the filtering device 200 includes a sealing member. The rear part of the filter element 220 is inserted into the ventilation opening 243a. The sealing member is sleeved outside the filter element 220, and the sealing member is located between the rear part of the filter element 220 and the surrounding part of the ventilation opening 243a. The filter element 220 can drive the sealing member to rotate in the ventilation opening 243a. The sealing member is used to seal the gap between the filter element 220 and the surrounding part of the ventilation opening 243a. In this way, on the one hand, the cooperation between the sealing member and the ventilation opening 243a provides a guiding effect for the rotation of the filter element 220, and to a certain extent, avoids relative sliding between the filter element 220 and the rear cover 243; on the other hand, the sealing member realizes dynamic sealing and avoids air leakage from the gap between the filter element 220 and the surrounding part of the ventilation opening 243a.

[0083] The specific structure of the filter element 220 is not limited. Exemplarily, in one embodiment, please refer to Figure 5 and Figure 6 , the filter element 220 includes a filter cartridge 221 and a filter screen. The ventilation air duct 220a is formed inside the filter cartridge 221. An air inlet 221a is formed on the circumferential surface of the filter cartridge 221, and the filter screen covers the air inlet 221a. In this way, the air flow passes through the filter screen, and after being filtered by the filter screen, the lint is isolated outside the filter cartridge 221, and the air flow removing the lint enters the ventilation air duct 220a through the filter screen.

[0084] In one embodiment, please refer to Figure 5 and Figure 6 , the filter cartridge 221 includes a front plate 2211 and a hollow cylindrical frame 2212.

The hollow space of the cylindrical frame 2212 is a ventilation air duct 220a. The rear opening of the cylindrical frame 2212 communicates with the ventilation opening 243a of the rear cover 243. A sealing member is sleeved on the rear opening of the cylindrical frame 2212, and an avoidance groove 220b is formed on the front plate 2211. The structure of the filter cartridge 221 is simple and easy to manufacture.

[0085] In one embodiment, please refer to Figure 3 , the base 100 is formed with a discharge channel 100b communicating with the lint chamber 100a, and the discharge channel 100b is located at the bottom of the lint chamber 100a. In this way, lint can be discharged from the lint chamber 100a through the discharge channel 100b.

[0086] In one embodiment, the base assembly includes a water storage box and a drainage pump. The water storage box communicates with the discharge channel 100b, and the drainage pump can discharge the lint and liquid in the water storage box. In this way, the lint and liquid in the lint chamber 100a both enter the water storage box through the discharge channel 100b, and the drainage pump pumps the lint and liquid in the water storage box to the outside of the dryer.

[0087] In one embodiment, please refer to Figure 3 , the part of the bottom surface of the lint chamber 100a close to the discharge channel 100b is lower than the part of the bottom surface of the lint chamber 100a far from the discharge channel 100b. In this way, the lint accumulated on the bottom surface of the lint chamber 100a is more likely to move into the discharge channel 100b under the action of gravity.

[0088] In one embodiment, please refer to Figure 3 , both the discharge channel 100b and the stopper 230 are located on the left side of the filter element 220, and the right part of the bottom surface of the lint chamber 100a is higher than the left part of the bottom surface of the lint chamber 100a. In this way, the lint blocked by the stopper 230 can fall to the location where the discharge channel 100b is located.
