Description

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

  Among dishwashers, there is a type in which a wall of the washing tank is a door that swings open and close for the convenience of loading and unloading dishes. In the case of this type of dishwasher, the detergent supply device is disposed on the door (for example, Patent Documents 1 and 2).

  FIG. 25 shows a layout of the detergent supply device in the same type of 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 is provided with 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. The rinse tank 104 is provided with a rinse replenishment port 107 and a rinse supply port 108. The rinse supplement port 107 is covered with a rinse supplement lid 109 so as to be opened and closed. The rinse supply port 108 is opened and closed by a rinse supply valve 111. During dish washing, the detergent replenishment-supply lid 106 and the rinse supply valve 111 are automatically opened and closed by a drive member (not shown). At this time, the opening / closing direction a100 of the detergent replenishment / supply lid 106 and the opening / closing direction a101 of the rinse supply valve 111 are both coincided with each other along the surface opening direction of the opening / closing door 102.

The detergent supply device 100 is deployed in the room 110 together with the door 102. For this reason, a relatively wide space is generated above the deployed detergent supply device 100. Therefore, when the operator replenishes the detergent tank 103 with detergent or when the rinse tank 104 is replenished with rinse, it is easy to secure a space necessary for replenishment.
Japanese Patent Application Laid-Open No. 2000-300498 Japanese Patent Laid-Open No. 9-14654

  By the way, in recent years, built-in drawer type dishwashers incorporated into kitchens have been developed. In the case of the same type of dishwasher, pull the entire washing tank out of the kitchen and put in and out the dishes.

  When the above-described detergent supply device 100 is incorporated into a built-in drawer type dishwasher, the above-described detergent replenishment work becomes complicated. That is, the detergent replenishment-supply port 105 and the rinse replenishment port 107 open along the surface development direction (substantially vertical surface direction) of the standing wall (corresponding to a state in which the open / close door 102 is closed). Moreover, the tableware accommodated in the washing tank 101 is arrange | positioned comparatively close to the standing wall. For this reason, the operator must put his hand into the narrow gap between the standing wall and the tableware from above and replenish detergent or rinse into the detergent replenishment-supply port 105 or the rinse replenishment port 107 which opens along the standing wall. .

  Here, in order to simplify the replenishment operation, for example, the detergent replenishment-supply port 105 may be protruded into the cleaning tank and opened upward. However, if the detergent replenishment-supply port 105 is opened upward, the opening / closing direction a100 of the detergent replenishment-supply lid 106 and the opening / closing direction a101 of the rinse supply valve 111 do not follow the same surface development direction. That is, the opening / closing direction a100 and the opening / closing direction a101 are along the plane development direction intersecting each other. This complicates the mechanism for driving the detergent replenishment-supply lid 106 and the rinse supply valve 111 when washing dishes.

  The detergent supply apparatus of the dishwasher of this invention was completed in view of the said subject. Therefore, an object of this invention is to provide the detergent supply apparatus with which the replenishment operation | work of the detergent from upper direction is easy.

  (1) In order to solve the above-mentioned problems, the detergent supply device for a dishwasher according to the present invention is arranged on a standing wall of a concave washing tank that opens upward, and opens and closes an upward detergent replenishing port for replenishing detergent into the tank. A detergent tank having a possible detergent replenishing lid and a detergent supply lid capable of opening and closing a detergent supply port for supplying the detergent into the tank of the washing tank; and a rinse supply port for supplying rinse into the tank of the washing tank A rinse tank having a rinse supply valve that can be opened and closed, a base having a vertical link portion that can open and close the detergent replenishment lid and the detergent supply lid, and a vertical link biasing member that biases the vertical link portion, The vertical link portion swings in a direction intersecting the vertical link portion, the rinse supply valve can be opened and closed, and the vertical link portion can be locked in a state where the urging force of the vertical link urging member is accumulated. A lateral link portion and a drive member for driving the lateral link portion; When the horizontal link portion locks the vertical link portion, the horizontal link portion swings by the driving force from the driving member, and the vertical link portion is released from the horizontal link portion. Thus, the detergent replenishment lid and the detergent supply lid are opened and closed by the biasing force of the vertical link biasing member, and when the vertical link portion is released from the horizontal link portion, The lateral link portion is swung by a driving force and can be switched to a rinse mode in which the rinse supply valve is opened and closed.

  That is, the detergent supply device of the present invention drives the vertical link portion and the horizontal link portion by the driving force of the driving member and the urging force of the vertical link urging member. A detergent replenishment lid and a detergent supply lid are interlocked with the vertical link portion. A rinsing supply valve is linked to the horizontal link portion. The horizontal link portion locks the vertical link portion in a state where the urging force of the vertical link urging member is accumulated. The drive member drives the lateral link portion.

  In the detergent mode, the lateral link portion is driven by the drive member, and the longitudinal link portion is released from the lateral link portion. For this reason, the vertical link portion swings by the biasing force of the stored vertical link biasing member. Therefore, the detergent replenishment lid and the detergent supply lid are opened and closed. On the other hand, in the rinse mode, the lateral link portion is driven by the drive member, and the rinse supply valve is opened and closed.

  Thus, in the detergent mode, the drive member functions as a trigger for releasing the urging force of the longitudinal link urging member. On the other hand, in the rinse mode, the drive member functions as an actuator that swings the lateral link portion.

  According to the detergent supply device of the present invention, it is possible to drive the vertical link portion and the horizontal link portion that move in the plane development direction intersecting each other by a single drive member. That is, it is possible to drive the detergent replenishment lid and the rinse supply valve that move in the plane development direction crossing each other by a relatively simple drive mechanism. Moreover, since the drive mechanism is simple, the detergent supply apparatus of the present invention is compact. Therefore, it is excellent in space saving. Further, the detergent replenishing port is opened upward. For this reason, it is easy to replenish the detergent.

  Note that “opening / closing” of the detergent replenishing lid, the detergent supply lid, and the rinse supply valve means at least one of an opening operation and a closing operation. Further, the opening operation and the closing operation include not only a switching operation between fully closed and fully opened, but also a switching operation between fully closed and a predetermined opening or between fully opened and a predetermined opening.

  (2) Preferably, the vertical link portion swings around a swing shaft of the detergent replenishing lid and a swing first shaft of the detergent supply lid. A vertical second arm interlocked with one arm, and the horizontal link portion is capable of opening and closing the rinse supply valve, the horizontal first arm contacting the vertical second arm, and the horizontal first arm A lateral link urging member that urges in the direction of the longitudinal second arm, and can be engaged with the lateral first arm by the urging force of the lateral link urging member, is driven by the drive member, and has the longitudinal link. A lateral second arm that can lock the longitudinal second arm in a state where the urging force of the urging member and the lateral link urging member is accumulated, and in the detergent mode, the driving force from the driving member The second horizontal arm swings, the second vertical arm is released from the second horizontal arm, and the vertical link The detergent supply lid opens and closes by swinging the vertical second arm by the biasing force of the biasing member, and the detergent replenishment lid opens and closes by interlocking the vertical first arm with the vertical second arm, The lateral first arm and the lateral second arm are engaged by the urging force of the lateral link urging member, and in the rinse mode, the lateral first arm and the lateral second arm engaged in the detergent mode. However, it is preferable that the rinse supply valve is opened and closed by swinging integrally with the driving force from the driving member.

  The vertical link portion includes a vertical first arm and a vertical second arm. The swing axis of the first vertical arm is coincident with the swing axis of the detergent replenishing lid. Similarly, the swing axis of the vertical second arm coincides with the swing axis of the detergent supply lid.

  The lateral link portion includes a lateral first arm, a lateral second arm, and a lateral link biasing member. The lateral first arm is interlocked with the rinse supply valve. The lateral second arm follows the drive member. The lateral link biasing member biases the lateral first arm in the longitudinal second arm direction and the lateral second arm direction. The vertical second arm is applied with the horizontal link biasing member and the biasing force of the vertical link biasing member. The horizontal second arm locks the vertical second arm in a state where the urging force is accumulated.

  In the detergent mode, first, the lateral second arm is swung by the driving force of the driving member. For this reason, the vertical second arm is released. Next, the vertical second arm is swung by the urging force of the accumulated vertical link urging member. For this reason, the detergent supply lid opens and closes. Then, the vertical first arm also swings in conjunction with the vertical second arm. For this reason, the detergent replenishment lid opens and closes. In addition, the lateral first arm engages the lateral second arm by the urging force of the accumulated lateral link urging member. For this reason, the horizontal first arm and the horizontal second arm are combined. In the rinse mode, the already combined horizontal second arm and horizontal first arm swing together by the driving force of the driving member. For this reason, the rinse supply valve opens and closes.

  According to this configuration, the number of parts constituting the vertical link portion and the horizontal link portion can be reduced. Moreover, the horizontal first arm and the horizontal second arm can be engaged and disengaged. For this reason, in the detergent mode, by separating both arms, it is possible to prevent the oscillating force of the lateral second arm from being transmitted to the lateral first arm and causing the rinse supply valve to malfunction. On the other hand, in the rinse mode, the swinging force of the lateral second arm can be reliably transmitted to the lateral first arm by engaging both arms. That is, the rinse supply valve can be operated reliably.

  According to the detergent supply apparatus of the present invention, the vertical link portion and the horizontal link portion that intersect each other can be driven by a single drive member. That is, it is possible to drive the detergent replenishment lid and the rinse supply valve that move in directions crossing each other with a relatively simple drive mechanism. Moreover, since the drive mechanism is simple, the detergent supply apparatus of the present invention is compact. Therefore, it is excellent in space saving. Further, the detergent replenishing port is opened upward. For this reason, it is easy to replenish the detergent.

A lateral engagement portion 416 is disposed on the upper rear surface. Also, a nail U-shaped frame 413 is arranged on the upper left side. Also, a pencil-shaped guided projection 415 projects from the upper front surface. The coalescing hole 414 has a rectangular frame shape. The coalescing hole 414 is disposed on the upper edge of the rear end of the horizontal second boss 410 so as to face the coalescing convex portion 404.

  The lateral link biasing spring 42 is mounted on the lateral first boss 400. The lateral link biasing spring 42 is compressed between the front bottom wall of the seat wall boss 210 c and the lateral first arm body 402. Accordingly, the lateral link biasing spring 42 biases the lateral first arm 40 toward the lateral second arm 41.

  Next, the link mechanism of the detergent supply device of this embodiment will be described. In FIG. 8, the expansion perspective view of the vertical link part of the detergent supply apparatus of this embodiment and the horizontal link part vicinity is shown. In FIG. 9, the expansion disassembled perspective view of the vertical link part of the detergent supply apparatus and the horizontal link part vicinity is shown. In FIG. 9, the detergent tank main body 210 is omitted. Also, these drawings show a state of a manual opening / closing mode described later.

  As shown in these drawings, in the manual opening / closing mode, the nail portion 63 of the drive member 6 is locked to the nail portion U-shaped frame 413 of the lateral second arm 41. Behind the lateral engagement portion 416 of the lateral second arm 41 is urged by the longitudinal link urging spring 5 and the longitudinal engagement portion 313 of the longitudinal second arm 31 is in pressure contact. That is, the vertical second arm 31 is pressed by the horizontal second arm 41 in a state where the urging force of the vertical link spring 5 is accumulated. The guided protrusion 415 of the horizontal second arm 41 is in contact with the guide rib 303 of the vertical first arm 30. The uniting hole 414 of the second horizontal arm 41 is opposed to the uniting projection 404 in the front-rear direction with a predetermined spacing.

  The inner protrusion 312 of the second vertical arm 31 is inserted into the guide frame 301 a of the inner fan 301 of the first vertical arm 30. On the other hand, the outer protrusion 314 of the vertical second arm 31 is in contact with the fan edge 302 a of the outer fan plate 302 of the vertical first arm 30. 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. That is, the horizontal first arm 40 is pressed by the vertical second arm 31 while being urged by the horizontal link biasing spring 42 in the direction of the horizontal second arm 41 and the direction of the vertical second arm 31. Further, the vertical second arm 31 is pressed down by the horizontal second arm 41 as described above. Accordingly, the urging forces of the longitudinal link urging spring 5 and the lateral link urging spring 42 are accumulated by the lateral second arm 41. The locking rib 403 of the lateral first arm 40 is engaged with the hook 224g of the rinse supply valve 224.

  Next, the movement of the detergent supply device of the present embodiment will be described in correspondence with the steps of the dishwasher. Table 1 shows a correspondence table between the steps of the dishwasher and the movement of the detergent supply device.

  As shown in the table, the dishwasher process is performed in the order of a tableware storage process, a preliminary cleaning process, a main cleaning process, a rinse process, a rinsing process, a drying process, and a tableware collection process. The detergent supply device has a manual opening / closing mode, a main detergent mode, a rinse mode, a manual return mode, and a sub detergent mode. The main detergent mode and the sub detergent mode are each included in the detergent mode of the present invention.

  In each mode, the detergent replenishing lid is switched between a fully closed position where the lid is completely closed, a fully opened position where the lid is completely opened, and a half open position where the lid is stopped between the fully closed position and the fully opened position. Similarly, the detergent supply damper is switched between the fully closed position and the fully open position by each mode. In the rinse mode, the rinse supply valve is first switched from the fully closed position to the fully open position, and then switched from the fully open position to the fully closed position. Hereinafter, it demonstrates concretely for every process of a dishwasher.

  In the tableware storing step, as shown in FIG. 1, first, the operator pulls out the cleaning tank 91 of the tableware washing machine 90. 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 process, the dishes are washed with water or warm 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), water is supplied from the detergent replenishing lid 212 in the half-open position and drained from the detergent supply damper 214 in the fully-open position, so that the detergent in the detergent tank body 210 does not adhere to the tableware. It is supplied into the washing tank of the washing machine.

  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 rinse-washed dishes are rinsed with water or warm 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, the single link member 6 can drive the vertical link portion 3 and the horizontal link portion 4 that move in the plane development direction intersecting each other. That is, the detergent replenishment lid 212, the detergent supply damper 214, and the rinse supply valve 224, which move in the plane development direction intersecting each other, can be driven by a relatively simple drive mechanism. Moreover, since the drive mechanism is simple, the detergent supply apparatus 1 is compact. Therefore, it is excellent in space saving. The detergent replenishing port 211 and the rinse replenishing port 221 are both open upward. For this reason, it is easy to replenish detergent and rinse.

  Moreover, according to the detergent supply apparatus 1 of this embodiment, the vertical link part 3 is comprised from the vertical 1st arm 30 and the vertical 2nd arm 31. FIG. The lateral link portion 4 includes a lateral first arm 40, a lateral second arm 41, and a lateral link biasing spring 42. For this reason, the number of parts is small. Further, the horizontal first arm 40 and the horizontal second arm 41 can be combined and separated by engagement / disengagement between the combining convex portion 404 and the combining hole 414. For this reason, in the main detergent mode or the sub-detergent mode, by separating both arms, the swinging force of the lateral second arm 41 is transmitted to the lateral first arm 40 to prevent the rinse supply valve 224 from malfunctioning. Can do. On the other hand, in the rinse mode, the swinging force of the lateral second arm 41 can be reliably transmitted to the lateral first arm 40 by engaging both arms. That is, the rinse supply valve 224 can be reliably operated.

  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 detergent replenishment lid 212 of the above embodiment switches between the fully open position and the fully closed position via the half-open position, but may be switched only between the fully open position and the fully closed position. 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).
