  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 in a built-in drawer type dishwasher, it becomes difficult to replenish the detergent and rinse. That is, the door 102 is not provided in the case of a type of dishwasher that pulls out the entire washing tank from the kitchen and takes in and out the dishes. Therefore, the detergent supply device 100 is disposed on a vertical wall extending in the vertical direction. Near the standing wall, the dishes stored in the washing tank 101 are arranged relatively densely. For this reason, the operator must put his hand into the narrow gap between the standing wall and the tableware from above and replenish the detergent replenishment / supply port 105 or the rinse replenishment port 107 with detergent or rinse.

  The detergent supply apparatus of the dishwasher of this invention was completed in view of the said subject. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a detergent supply device for a dishwasher that can be easily replenished with detergent and rinse from above.

  (1) In order to solve the above-described problem, a detergent supply device for a dishwasher according to the present invention includes a substrate through which a detergent replenishment port and a rinse replenishment port penetrate front and back, fixed to the back surface of the substrate, A detergent tank that is replenished with a detergent, and a rinse tank that is fixed to the back surface of the substrate and that is replenished with the rinse through the rinse replenishing port, and has a recessed cleaning tank standing upward The detergent replenishing device of the dishwasher is arranged in the horizontal direction in the upper part of the substrate, the detergent replenishing port and the rinse replenishing port.

  According to the detergent supply device of the present invention, the detergent replenishing port and the rinse replenishing port are disposed on the top of the substrate. That is, it is arrange | positioned in the comparatively high position of the standing wall of a washing tank. For this reason, at the time of replenishing detergent and rinse, the operator's hand hardly interferes with the tableware stored in the tank of the cleaning tank. Therefore, the detergent and rinse can be easily replenished. The detergent replenishing port and the rinse replenishing port are arranged side by side in the horizontal direction. For this reason, it is convenient.

  (2) Preferably, the substrate has a rectangular shape, and the surface of the substrate is embedded in the standing wall in a state where the substrate is exposed in the tank of the cleaning tank, and the rinse tank is formed on the back surface of the substrate. The detergent tank has an L-shape extending along one side edge and a lower edge, and the detergent tank includes the other side edge of the back surface of the substrate facing the one side edge, the upper edge, and the rinse tank. It is better to have a configuration surrounded by

  The substrate is embedded in the standing wall. For this reason, if the thickness of the detergent supply device is large, the thickness of the standing wall itself becomes large. For example, in the case of a built-in drawer type dishwasher, the installation space of the dishwasher in the kitchen is determined. For this reason, if the thickness of the standing wall is increased, the capacity of the cleaning tank must be reduced accordingly.

  In this regard, according to the present configuration, the limited space on the back surface of the substrate can be used efficiently. Therefore, the thickness of the detergent supply device can be reduced. The rinse tank has an L shape extending along one side edge and the lower edge of the substrate. For this reason, according to this structure, although the thickness of a detergent supply apparatus is small, the capacity | capacitance of a rinse tank can be ensured comparatively large.

  As shown in these drawings, the substrate 20, the detergent tank 210, the rinse tank 220, the rinse supply valve 224, the vertical link portion 3, the horizontal link portion 4, and the drive member 6 are arranged on the rear surface side of the detergent supply device 1. Has been.

  The entire rinsing tank 220 is made of a transparent resin and has a concave shape. The rinse tank 220 is laid down on a rinse tank frame 206 disposed on the rear surface of the substrate 20 (the back surface of the substrate in the present invention). The rinse tank 220 is joined to the rear surface of the substrate 20. The rinse tank 220 has an L shape extending from the left edge (one side edge in the present invention) to the lower edge of the rear surface of the substrate 20. The rinse replenishment port 221 in FIG. 3 communicates with the L-shaped upper end portion of the rinse tank 220. The rinse supply port 223 communicates with the L-shaped lower end portion of the rinse tank 220.

  The rinse supply valve 224 is disposed at the lower end of the L-shape of the rinse tank 220 so as to face the rinse supply port 223 in the front-rear direction. The rinse supply valve 224 includes a valve seat 224a, a valve body 224b, a valve body biasing spring 224c, and a pressing member 224d. The valve seat 224a is fixed to the rinse tank 220. A holding member 224d is locked to the valve seat 224a. In a space defined by the valve seat 224a and the pressing member 224d, a valve body 224b in which a valve body biasing spring 224c is mounted around the body portion is disposed so as to be capable of reciprocating. A hook 224g is formed at the right end of the valve body 224b. The hook 224g protrudes to the right side from the pressing member 224d.

  An LED seat 220a protrudes rearward from the upper rear wall of the rinse tank 220. An LED 220b is mounted on the LED seat 220a. The LED 220b is disposed to face the light guide 222b of FIG. 2 through the rear wall of the rinse tank 220. A lower wall boss 220e protrudes from the lower wall of the rinse tank 220. A nail-like float support member 220d is inserted into the tank from the lower wall boss 220e. On the outer peripheral surface of the float support member 220d, a ring-shaped float 220c made of resin is mounted so as to be able to reciprocate in the vertical direction. On the other hand, an electric sensor 7 for detecting the position of the float 220c is accommodated in the float support member 220d. When the rinsing liquid level falls below a predetermined level, the LED 220b is turned on by an instruction from the sensor 7. The light from the LED 220b passes through the rear wall of the transparent rinse tank 220 and the light guide 222b shown in FIG. 2 and is visually recognized by the operator from above. That is, the operator can recognize the lack of rinsing by the light emission of the light guide 222b.

  The detergent tank 210 is made of resin and has a rectangular concave shape. The detergent tank 210 is laid down on a detergent tank frame 205 disposed on the rear surface of the substrate 20 via a rubber packing (not shown). That is, the detergent tank 210 is surrounded by the right edge (the other edge in the present invention), the upper edge, and the rinse tank 220 of the substrate 20. Inside the detergent tank 210, the detergent replenishment lid 212 and the detergent supply damper 214 are arranged.

  The drive member 6 is fixed to the rear wall of the detergent tank 210. The drive member 6 includes a reciprocating drive protrusion 60 that can reciprocate in the left-right direction by a built-in solenoid coil (not shown).

  The vertical link portion 3 includes a vertical first arm 30 and a vertical second arm 31. The vertical first arm 30 passes through the right wall of the detergent tank 210 and is fixed to the detergent replenishing lid 212 by a screw 304. Therefore, the vertical first arm 30 and the detergent replenishing lid 212 swing integrally around the vertical first swing axis x1.

  The vertical second arm 31 passes through the right wall of the detergent tank 210 and is fixed to the detergent supply damper 214 with a screw 316. Accordingly, the vertical second arm 31 and the detergent supply damper 214 swing integrally around the vertical second swing axis x2. The vertical first arm 30 and the vertical second arm 31 are interlocked.

  The lateral link portion 4 includes a lateral first arm 40 and a lateral second arm 41. The lateral first arm 40 is connected to the hook 224g of the rinse supply valve 224. The second horizontal arm 41 is locked to the reciprocating drive protrusion 60 of the drive member 6. The horizontal second arm 41 and the horizontal first arm 40 can swing around a horizontal swing axis y (screw 43). Further, the horizontal second arm 41 and the horizontal first arm 40 can be combined and separated.

  Next, the link mechanism of the detergent supply device of this embodiment will be briefly described. In the initial state, the vertical second arm 31 stores an urging force acting in the clockwise direction in FIG. The vertical second arm 31 is locked to the horizontal second arm 41 in this state. The horizontal second arm 41 and the horizontal first arm 40 are separated.

  When opening the detergent replenishing lid 212 and the detergent supply damper 214, the drive member 6 is energized. When energized, the reciprocating drive protrusion 60 slides leftward by electromagnetic force. For this reason, the horizontal second arm 41 locked to the reciprocating drive protrusion 60 also swings in the right direction. When the horizontal second arm 41 swings, the vertical second arm 31 is released from the horizontal second arm 41. Therefore, the vertical second arm 31 is swung by the accumulated urging force, and the detergent supply damper 214 is opened. Further, the vertical first arm 30 swings in conjunction with the vertical second arm 31. For this reason, the detergent replenishment lid 212 is also opened.

  When the rinse supply valve 224 is opened, the lateral second arm 41 and the lateral first arm 40 are combined by an urging spring (not shown). Then, both the arms are integrally swung by the driving member 6. Therefore, the rinse supply valve 224 driven by the lateral first arm 40 is opened.

  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 detergent replenishing port 211 and the rinse replenishing port 221 are arranged on the upper portion of the substrate 20. That is, the cleaning tank 91 is disposed at a relatively high position on the standing wall 92. For this reason, the operator's hand is unlikely to interfere with the tableware 95 housed in the tank of the cleaning tank 91 when the detergent and rinse are replenished. Therefore, the detergent and rinse can be easily replenished. The detergent replenishing port 211 and the rinse replenishing port 221 are arranged side by side in the horizontal direction. For this reason, it is convenient.

  Moreover, according to the detergent supply apparatus 1 of this embodiment, the limited space on the back surface (rear surface) of the substrate 20 can be efficiently used. For this reason, the thickness of the detergent supply apparatus 1 can be reduced. Therefore, the thickness of the rear wall 92 can be reduced. In addition, the capacity of the cleaning tank 91 can be increased. The rinse tank 220 extends from the left edge to the lower edge of the back surface of the substrate 20. For this reason, although the thickness of the detergent supply apparatus 1 is small, the capacity | capacitance of the rinse tank 220 is comparatively large.

  Further, according to the detergent supply device 1 of the present embodiment, the rinse replenishment port 221 communicates with the L-shaped upper end portion of the rinse tank 220. On the other hand, the rinse supply port 223 communicates with the L-shaped lower end portion of the rinse tank 220. For this reason, it is difficult for a dead water area to occur in the rinse tank 220. That is, the rinse can be easily supplied into the tank of the cleaning tank 95 by the action of gravity.

  Further, according to the detergent supply device 1 of the present embodiment, the detergent replenishing port 211 and the rinse replenishing port 221 are both upward. In this respect, the detergent and rinse can be easily replenished.

  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 supply device 1 of the present embodiment is not limited to the built-in drawer type, and can be employed in any type of dishwasher having a standing wall (the rear wall 92 in FIG. 1).
