Description

  The present invention relates to a detergent supply device for a dishwasher that houses and cleans tableware in a washing tank.

  FIG. 25 shows a layout of the detergent supply device in the dishwasher. As shown in the figure, one wall of the cleaning tank 101 is an open / close door 102 whose lower end is pivotally supported. A detergent supply device 100 is embedded on the back surface of the open / close door 102.

  In FIG. 26, the enlarged view of the detergent supply apparatus of the dishwasher is shown. As shown in the figure, the detergent supply device 100 is provided with a detergent tank 103 and a rinse tank 104. The detergent tank 103 includes a storage chamber 112 and a detergent replenishment / supply port 105. The detergent replenishment / supply port 105 is covered with a detergent replenishment / supply lid 106 so as to be opened and closed.

  Before washing the dishes, the operator manually opens the detergent replenishment-supply lid 106 and replenishes the storage chamber 112 with detergent. Tableware washing is performed in the order of the preliminary washing step and the main washing step. That is, first, the dishes are washed with water in the preliminary washing step, and then the dishes are washed with a detergent in the main washing step. In the main cleaning step, the detergent replenishment / supply lid 106 is automatically opened, and the detergent is supplied from the storage chamber 112 into the tank of the cleaning tank 101.

  By the way, the detergent is powdery. For this reason, when supplying the detergent in the main cleaning process, the detergent may aggregate due to moisture in the preliminary cleaning process, which is a previous process, and may adhere to the inner surface of the storage chamber 112. In this case, it becomes difficult to supply the detergent into the washing tank 101.

In view of this point, Patent Document 1 introduces a detergent supply device that causes the detergent in the storage chamber 112 to flow into the tank by water discharged from the water supply pipe into the tank of the cleaning tank 101.
Japanese Patent Laid-Open No. 2000-300498 (FIG. 5)

  However, in the case of the detergent supply device described in the same document, as in the case of the detergent supply device shown in FIGS. 25 and 26, it is the detergent replenishment that communicates the storage chamber 112 with the inside of the washing tank 101. Only the supply port 105 is provided. For this reason, water enters and exits the storage chamber 112 via the single detergent replenishment-supply port 105. Accordingly, the incoming and outgoing water flows collide with each other and the water does not flow easily.

  The detergent supply apparatus of the present invention has been completed in view of the above problems. Therefore, an object of this invention is to provide the detergent supply apparatus which has a water flow path which is easy to supply a detergent to the washing | cleaning chamber of a washing tank.

  (1) In order to solve the above-mentioned problem, a detergent supply device for a dishwasher according to the present invention is a detergent supply device for a dishwasher that is disposed on a standing wall of a concave washing tank that opens upward and divides a washing chamber. A storage chamber for storing a detergent; a first communication port communicating the storage chamber and the cleaning chamber; and the storage chamber and the cleaning chamber communicated independently of the first communication port. A detergent tank having a second communication port, a first lid capable of opening and closing the first communication port, and a second lid capable of opening and closing the second communication port, and storing the detergent. When supplying the cleaning chamber from the chamber, the first lid and the second lid are opened, and the passage connecting the first series port, the storage chamber, and the second communication port to the cleaning chamber. The detergent is guided to the cleaning chamber by securing a water channel and flowing water through the water channel.

  According to the detergent supply device of the present invention, when supplying the detergent from the storage chamber to the cleaning chamber (for example, at the time of the main cleaning step), the water passage connecting the first series of ports, the storage chamber, and the second communication port. Is formed. By flowing water (including hot water) through this water passage, the detergent in the storage chamber is guided to the cleaning chamber.

  According to the detergent supply device of the present invention, a water passage can be formed by using one of the first serial port and the second communication port as an inlet and the other as an outlet. That is, it is possible to form a water flow path through which water flows in the order of the first continuous port → the storage chamber → the second communication port or the second communication port → the storage chamber → the first continuous port. For this reason, the flow of water is smooth. Therefore, it is possible to smoothly supply the detergent to the cleaning chamber in a water flow.

  (2) Preferably, when supplying the detergent from the storage chamber to the cleaning chamber, the first lid is held in a half-open position between a fully open position and a fully closed position, and the second lid is in a fully open position. It is better to have a configuration to be held. The fully open position refers to a position where the mouth is fully opened. The fully closed position refers to a position where the mouth is fully closed. The half-open position refers to a predetermined position between the fully open position and the fully closed position.

  According to this configuration, the first lid is held in the half-open position. Accordingly, the first series of openings are also in a half-open state. For this reason, compared with the case where both a 1st cover and a 2nd cover are a full open position, the water flow resistance in a water flow path becomes large. That is, the flow rate of water becomes slow. According to this configuration, the supply speed of the detergent to the cleaning chamber can be reduced. In other words, the detergent can be continuously supplied in small amounts for a long time.

  (3) Preferably, in the configuration of the above (2), the first communication port is a detergent replenishment port for replenishing the storage chamber with the detergent, and the second communication port is located below the detergent replenishment port. A detergent supply port that supplies the detergent to the cleaning chamber, the first lid is a detergent replenishment lid that can open and close the detergent replenishment port, and the second lid has the detergent supply port It is a detergent supply lid that can be opened and closed, and it is preferable that the water flow through the water passage in the order of the detergent replenishing port, the storage chamber, and the detergent supply port.

  According to this configuration, a water passage is secured in the direction from top to bottom. For this reason, water and detergent easily flow according to gravity. The detergent replenishing port is arranged above the detergent supply port. For this reason, when the detergent supply device is arranged on a standing wall that does not open and close, it is easy to replenish the detergent.

  (4) Preferably, in the configuration of (3) above, after the tableware storing step of storing tableware in the cleaning chamber and replenishing the storage chamber with the detergent, the detergent replenishing lid is in the fully closed position and the fully opened position In any case, in the main cleaning step of cleaning the tableware with the detergent, it is preferable that the detergent replenishing lid be held in the half-open position.

  According to this configuration, the detergent replenishment lid is automatically switched to the half-open position regardless of the position of the detergent replenishment lid after the tableware storage step. Therefore, the detergent can be reliably supplied to the cleaning chamber in the main cleaning process.

The cleaning tank 91 protrudes backward (in the room) from the design panel 93 of the kitchen 9. Next, the operator places the tableware 95 in the tableware basket 94. Then, the operator manually opens the detergent replenishment lid 212 shown in FIG. That is, in this step, the detergent supply device 1 is in the manual open / close mode.

  In FIG. 10, the model right side exploded view of the vertical link part of the detergent supply apparatus of this embodiment and a horizontal link part is shown. FIG. 11 shows a transparent right side view of the detergent supply apparatus in the manual open / close mode (fully closed position). (A) is the transparent right view of a vertical link part and a horizontal link part. (B) is the permeation | transmission right side view in a detergent tank main body. For convenience of explanation, as shown in FIG. 10, each member is schematically shown as deformed.

  As shown in FIG. 11, when the operator opens the detergent replenishing lid 212 from the fully closed position, the vertical first arm 30 connected by the detergent replenishing lid 212 and the vertical first swing shaft x1 also rotates clockwise in the figure. Swing. A fully closed positioning throttle 301b is disposed at one end of the guide frame 301a. In the fully closed position, the fully closed positioning throttle 301b interferes with the inner protrusion 312 of the vertical second arm 31. Due to this interference, the fully closed position is determined. When opening the detergent replenishment lid 212, the inner protrusion 312 relatively gets over the fully closed positioning throttle 301b. When the overlying inner protrusion 312 moves to the other end of the guide frame 301a, the detergent replenishment lid 212 is switched to the fully open position.

  In FIG. 12, the permeation | transmission right side view in the manual opening / closing mode (fully opened position) of the detergent supply apparatus of this embodiment is shown. (A) is the transparent right view of a vertical link part and a horizontal link part. (B) is the permeation | transmission right side view in a detergent tank main body.

  The operator who opened the detergent replenishing lid 212 replenishes the detergent tank body 210 with the detergent as shown in the figure. If the light guide column 222b shown in FIG. 2 is lit, the operator manually opens the rinse replenishing lid 222 and replenishes the rinse. Then, the detergent replenishment lid 212 is again swung to the fully closed position shown in FIG. That is, in the manual opening / closing mode, as shown in Table 1 above, the detergent replenishment lid 212 is switched in the order of full closing → full opening → full closing again.

  The operator who closed the detergent replenishing lid 212 pushes the cleaning tank 91 into the kitchen 9 as shown in FIG. And the start button of the operation part (not shown) divided into the design panel 93 is pushed. Thereby, dishwashing is started.

  In the preliminary washing step, the dishes are washed with water. In this step, the detergent supply device does not operate.

  In the main cleaning process, as shown in Table 1 above, the main detergent mode and the sub detergent mode are alternatively performed. That is, in the manual opening / closing mode, when the detergent replenishment lid 212 after the detergent is replenished is closed to the fully closed position, the main detergent mode is performed. On the other hand, when the detergent replenishment lid 212 after the detergent is replenished remains in the fully opened position (that is, when the operator forgets to close), the sub detergent mode is performed. Here, the main detergent mode will be described. The sub detergent mode will be described later.

  In FIG. 13, the rear view in the main detergent mode (fully closed position) of the vertical link part and horizontal link part of the detergent supply apparatus of this embodiment is shown. FIG. 14 shows a rear view of the vertical link portion and the horizontal link portion in the main detergent mode (opening). FIG. 15 shows a rear view of the vertical link portion and the horizontal link portion in the main detergent mode (half-open position). In FIG. 16, the schematic diagram of the engagement state of a vertical 2nd arm and a horizontal 2nd arm is shown. In FIG. 17, the permeation | transmission right side view in the main detergent mode (half-open position) of the detergent supply apparatus of this embodiment is shown. (A) is the transparent right view of a vertical link part and a horizontal link part. (B) is the permeation | transmission right side view in a detergent tank main body. Note that FIG. 16A is a view as viewed in A of FIG. Moreover, FIG.16 (b) is a B view of FIG. FIG. 16C is a C view of FIG.

  In the fully closed position shown in FIG. 11, the vertical second arm 31 is placed on the rear surface of the horizontal engagement portion 416 of the horizontal second arm 41 as shown by the solid line hatching in FIG. The vertical engagement portion 313 is in pressure contact. In this state, when the solenoid coil of the drive member 6 is energized, the reciprocating drive protrusion 60 is immersed in the case as shown in FIGS. 13 and 16A. Here, the nail 63 integrated with the reciprocating protrusion 60 is locked to the nail U-shaped frame 413 of the second horizontal arm 41. For this reason, the horizontal second arm 41 swings counterclockwise in FIG. 13 about the horizontal swing axis y. Accordingly, the lateral engagement portion 416 slides leftward with respect to the vertical engagement portion 313. Then, as shown in FIGS. 14 and 16 (b), the vertical engagement portion 313 is released from the lateral engagement portion 416. In FIG. 16B, the vertical engagement portion 313, that is, the vertical second arm 31 is biased forward by the vertical link biasing spring 5. Therefore, as shown in FIG. 17A, the vertical second arm 31 swings clockwise around the vertical second swing axis x2. The vertical second arm 31 and the detergent supply damper 214 are connected by a vertical second swing shaft x2. Accordingly, as shown in FIG. 17B, the detergent supply damper 214 also swings clockwise in the drawing, and switches from the fully closed position to the fully open position.

  On the other hand, as shown by dotted line hatching in FIG. 14, the guided projection 415 of the sliding second horizontal arm 41 is in sliding contact with the guide rib 303 of the first vertical arm 30. For this reason, when the guided protrusion 415 slides leftward, the guide rib 303 is pushed upward. This push-up triggers the first vertical arm 30 to swing. As shown in FIG. 17A, the outer projection 314 of the vertical second arm 31 is in sliding contact with the fan edge 302 a of the outer fan plate 302 of the vertical first arm 30. The swinging force of the vertical second arm 31 is transmitted to the vertical first arm 30 through this sliding contact. Therefore, the vertical first arm 30 swings clockwise in FIG. 17 about the vertical first swing axis x1. The vertical first arm 30 and the detergent replenishing lid 212 are connected by a vertical first swing shaft x1. For this reason, as shown in FIG. 17 (b), the detergent replenishing lid 212 also swings clockwise in the drawing, and switches from the fully closed position to the half open position. This swinging ends when the half-open positioning protrusion 317 of the vertical second arm 31 comes into contact with the contact seat 210f of the detergent tank body 210 shown in FIG. That is, the half-opening positioning projection 317 biased by the vertical link biasing spring 5 abuts against the abutment seat 210f, whereby the detergent replenishment lid 212 is held at the half-open position. As shown in FIG. 17 (b), a water passage 7 is formed between the half-open detergent replenishing port 211, the storage chamber 215, and the fully-open detergent supply port 213. As water flows through the water passage 7, the detergent in the detergent tank body 210 is supplied to the cleaning chamber 910 in FIG.

  Further, as shown in FIG. 17A, the pressing projection 315 of the vertical second arm 31 swings clockwise in the drawing, so that the horizontal first arm 40 is moved by the biasing force of the horizontal link biasing spring 42. Move backwards. For this reason, the combining convex portion 404 of the horizontal first arm 40 is inserted and locked in the combining hole 414 of the horizontal second arm 41. That is, the horizontal first arm 40 and the horizontal second arm 41 are combined.

  Further, as shown in FIG. 16C, when the longitudinal engagement portion 313 is released from the lateral engagement portion 416, the energization to the drive member 6 is cut off. For this reason, the reciprocating protrusion 60 and the nail part 63 are restored to the right by the biasing force of the protrusion biasing spring 61. Accordingly, the lateral second arm 41 also moves backward to the position shown in FIG.

  As described above, in this mode, the detergent replenishment lid 212 is switched from the fully closed position to the half open position. Further, the detergent supply damper 214 is switched from the fully closed position to the fully opened position. Moreover, the horizontal first arm 40 and the horizontal second arm 41 are united.

  In the rinsing step, as shown in Table 1 above, the rinsing mode is switched. In FIG. 18, the rear view in the rinse mode (fully opened position) of the vertical link part and horizontal link part of the detergent supply apparatus of this embodiment is shown. As shown in the figure, in this mode, the energized drive member 6 is driven again. Similar to the main detergent mode described above, the second horizontal arm 41 swings leftward when pulled by the nail portion 63 of the drive member 6. Here, the horizontal first arm 40 and the horizontal second arm 41 are united. For this reason, the horizontal first arm 40 and the horizontal second arm 41 integrally swing counterclockwise around the horizontal swing axis y. Therefore, the locking rib 403 at the lower end of the lateral first arm 40 swings in the right direction. The locking rib 403 is engaged with the hook 224g of the rinse supply valve. Pulled by the locking rib 403, the hook 224g, that is, the valve body 224b shown in FIG. 7 also slides to the right. For this reason, the seal plate 224f is separated from the valve seat 224a against the urging force of the valve body urging spring 224c. Through the gap between the seal plate 224f and the valve seat 224a, the rinse in the rinse tank main body 220 is supplied into the cleaning tank from the rinse supply port 223 shown in FIG. When the energization to the driving member 6 is interrupted, the second horizontal arm 41 swings in the right direction and returns as in the above-described main detergent mode. For this reason, the lateral first arm 40 swings leftward. Then, the valve body 224b slides leftward by the biasing force of the valve body biasing spring 224c, and the seal plate 224f is seated again on the valve seat 224a.

  Thus, in this mode, first, the rinse supply valve 224 is switched from the fully closed position to the fully open position by the electromagnetic force of the drive member 6. Next, the rinsing supply valve 224 is switched from the fully open position to the fully closed position again by the urging force of the valve body urging spring 224c.

  In the rinsing step, the dishes after the rinse cleaning are rinsed with water. In the drying process, the rinsed tableware is dried with warm air. In both of these steps, the detergent supply device does not operate. After drying for a predetermined time, the dishwasher automatically stops.

  In the tableware collection step, the tableware after drying is collected. That is, as shown in FIG. 1, the operator first pulls out the washing tank 91 of the dishwasher 90 backward. Next, the operator collects the tableware 95 from the tableware basket 94. Then, the operator manually opens the detergent replenishment lid 212 shown in FIG. In this step, the detergent supply device 1 is in the manual return mode.

  In FIG. 19, the permeation | transmission right side view in the manual return mode (half-open position) of the detergent supply apparatus of this embodiment is shown. (A) is the transparent right view of a vertical link part and a horizontal link part. (B) is the permeation | transmission right side view in a detergent tank main body. FIG. 20 shows a transparent right side view of the detergent supply device in the manual return mode (opening). (A) is the transparent right view of a vertical link part and a horizontal link part. (B) is the permeation | transmission right side view in a detergent tank main body.

  As shown in FIG. 19, when the operator opens the detergent replenishing lid 212 from the half-open position, the vertical first arm 30 connected to the detergent replenishing lid 212 by the vertical first swing shaft x1 also swings clockwise in the figure. Move. When the vertical first arm 30 swings by a predetermined angle, the return slope 301c of the inner fan plate 301 of the vertical first arm 30 contacts the inner protrusion 312 of the vertical second arm 31, as shown in FIG. Touch.

  FIG. 21 shows a transparent right side view of the detergent supply device in the manual return mode (while the detergent supply damper is closed). (A) is the transparent right view of a vertical link part and a horizontal link part. (B) is the permeation | transmission right side view in a detergent tank main body. When the return slope 301c contacts the inner protrusion 312, the vertical second arm 31 swings counterclockwise in the figure. For this reason, the detergent supply damper 214 connected by the vertical second arm 31 and the vertical second swing shaft x2 also swings counterclockwise as shown in FIG.

  Here, the vertical second arm 31 is biased by the vertical link biasing spring 5 in the clockwise direction in the drawing. Therefore, the operator opens the detergent supply lid 212 while resisting the biasing force of the vertical link biasing spring 5. Further, the pressing protrusion 315 of the vertical second arm 31 is in contact with the vertical second receiving seat 405 of the horizontal first arm 40. For this reason, when the operator swings the vertical second arm 31, the horizontal first arm 40 pressed by the pressing protrusion 315 slides forward while resisting the biasing force of the horizontal link biasing spring 42. . By this slide, the lateral first arm 40 is separated from the lateral second arm 41. Thus, the operator opens the detergent supply lid 212 while resisting not only the biasing force of the vertical link biasing spring 5 but also the biasing force of the horizontal link biasing spring 42.

  By the way, in order to return to the manual opening / closing mode, as shown in FIG. 16A, the vertical second arm 31 storing the urging forces of the vertical link urging spring 5 and the lateral link urging spring 42 is used. The vertical engaging portion 313 needs to be locked again by the horizontal engaging portion 416 of the horizontal second arm 41. In other words, it is necessary to reset the vertical engagement portion 313 to the rear of the lateral engagement portion 416. Hereinafter, a mechanism for reset will be described. FIG. 22 shows a positional relationship diagram between the second vertical arm and the second horizontal arm in the manual return mode (during opening) of the detergent supply device of the present embodiment. FIG. 23 shows a schematic diagram of the re-engagement state between the vertical second arm and the horizontal second arm. For convenience of explanation, in FIG. 22, the vertical second arm 31 is drawn by a one-dot chain line. As shown in FIG. 22, a tapered portion 417 is formed on the right surface of the standing wall where the lateral engagement portion 416 is disposed in the lateral second arm 41. The tapered portion 417 is formed so as to be pointed forward. The vertical engaging portion 313 of the vertical second arm 31 that is swung by the operator is in sliding contact with the tapered portion 417. That is, as shown in FIG. 23A, the vertical engagement portion 313 approaches the taper portion 417 from the front. Then, as shown in FIG. 23B, the left end of the vertical engagement portion 313 contacts the taper portion 417. When the left end of the vertical engagement portion 313 comes into contact with the taper portion 417, the stress from the front to the rear of the vertical engagement portion 313 is converted into the stress from right to left via the taper portion 417. Due to this converted stress, the reciprocating drive protrusion 60 is immersed in the case of the drive member 6. And as shown in FIG.23 (c), the vertical engaging part 313 gets over the taper part 417. FIG. Thereafter, as shown in FIG. 23 (d), the vertical engagement portion 313 is reset behind the lateral engagement portion 416. That is, it returns to the fully open position in the manual opening / closing mode shown in FIG.

  As described above, in this mode, the detergent replenishment lid is manually returned from the half-open position to the fully open position in the manual open / close mode. Further, the detergent supply damper returns from the fully open position to the fully closed position.

  Next, the sub detergent mode will be described. This mode is performed when the detergent replenishment lid 212 after the detergent replenishment is in the fully open position at the end of the manual opening / closing mode of the tableware storage process. FIG. 24 shows a positional relationship diagram between the inner fan and the vertical second arm in this mode. In addition, what is shown in the figure is an extract of the inner fan 301 and the vertical second arm 31 from the previous FIG. 12 showing the detergent replenishing lid fully opened position in the manual open / close mode. In FIG. 12, when the drive member 6 is driven, the vertical second arm 31 is released from the horizontal second arm 41 as in the main detergent mode. The released vertical second arm 31 swings clockwise in the figure by the biasing force of the vertical link biasing spring. When swinging, as shown in FIG. 24, the inner projection 312 of the vertical second arm 31 gets over the return slope 301c. The return slope 301 c, that is, the vertical first arm 30 oscillates counterclockwise in the figure due to the stress received from the inner protrusion 312 at this time. The swing of the vertical second arm 31 is ended when the half-open positioning protrusion 317 in FIG. 10 contacts the contact seat 210f as in the main detergent mode.

  In this way, in this mode, the detergent replenishment lid 212 is switched from the fully open position to the half open position shown in FIG. Further, the detergent supply damper 214 is switched from the fully closed position to the fully opened position. Moreover, the horizontal first arm 40 and the horizontal second arm 41 are united as in the main detergent mode. In addition, after this mode, the rinse process, rinse process, drying process, and tableware collection | recovery process which were mentioned above are performed in order.

  Next, the effect of the detergent supply device of this embodiment will be described. According to the detergent supply device 1 of the present embodiment, as shown in FIG. 17B, in the main cleaning process, the one-way water passage 7 connected to the detergent replenishment port 211 → the storage chamber 215 → the detergent supply port 213 is provided. It is formed. For this reason, the flow of water is smooth. Accordingly, the detergent can be smoothly supplied to the cleaning chamber 910 in a water flow.

  In the main cleaning process, the detergent replenishment lid 212 is held in the half-open position. Accordingly, compared with the case where both the detergent replenishing lid 212 and the detergent supply lid 214 are in the fully open position, the water passage resistance in the water passage 7 is increased. That is, the flow rate of water becomes slow. According to this configuration, the supply speed of the detergent to the cleaning chamber 910 can be reduced. In other words, the detergent can be continuously supplied in small amounts for a long time.

  Moreover, according to the detergent supply apparatus 1 of this embodiment, the water flow path 7 is ensured in the direction from the top to the bottom. For this reason, water and detergent easily flow according to gravity. Further, the detergent replenishment port 211 is disposed above the detergent supply port 213. In addition, the detergent replenishment port 211 is open upward. For this reason, it is easy to replenish the detergent.

  Further, according to the detergent supply device 1 of the present embodiment, when the detergent replenishment lid 212 is in the fully closed position after the tableware storage step, the main detergent mode causes the detergent replenishment lid 212 to be in the fully open position after the tableware storage step. In the sub-detergent mode, the detergent replenishment lid 212 is automatically switched to the half-open position in the main cleaning process. Therefore, the detergent can be reliably supplied to the cleaning chamber 910 in the main cleaning process.

  Further, according to the detergent supply device 1 of the present embodiment, the detergent replenished to the storage chamber 215 by the operator stays on the detergent supply damper 214 immediately below the storage chamber 215. In the main cleaning step shown in Table 1, the detergent supply damper 214 swings and switches from the closed position to the open position. That is, the inclination of the detergent supply damper 214 is increased. Therefore, the detergent staying on the detergent supply damper 214 slides under its own weight in the cleaning chamber 901 so that the sand loaded on the dump truck's bed slides down to the ground. Also in this point, the detergent supply device 1 of the present embodiment can easily supply the detergent to the cleaning chamber 901.

  Further, according to the detergent supply device 1 of the present embodiment, the opening width of the detergent replenishing port 211 when the detergent replenishing lid 212 is in the half-open position is narrow. For this reason, it is difficult for the operator to replenish the storage chamber 215 with the detergent in the half-open position. That is, in order to replenish the detergent, it is necessary to perform the manual return mode shown in Table 1 above. Therefore, it is possible to prevent the operator from replenishing the detergent with the detergent replenishing lid 212 in the half-open position, in other words, with the detergent supply damper 214 in the fully open position, and the detergent leaking from the detergent supply port 213.

  The embodiment of the detergent supply device of the present invention has been described above. However, the embodiment is not particularly limited to the above embodiment. Various modifications and improvements that can be made by those skilled in the art are also possible. For example, the manual return mode shown in Table 1 may be performed in the tableware storage process. All you have to do is before the manual open / close mode. Moreover, the detergent may not be powdery. For example, it may be a highly viscous gel. Moreover, the detergent supply apparatus 1 of this embodiment is employable not only for a built-in drawer type but for all types of dishwashers having a standing wall (the rear wall 92 in FIG. 1).
