[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. FIG. 1 is a front view of an automatic detergent rinsing device 10 for a dishwasher equipped with a rinse metering adjustment shaft 61 of the present invention. FIG. 3 is an AA enlarged sectional view of FIG. The automatic detergent rinse dispenser 10 for a dishwasher equipped with the rinse metering adjustment shaft 61 of the present invention is basically mounted on the inner surface of the door of the dishwasher as in the conventional configuration, and the detergent is attached to the main body panel 11. It has an inlet 16 and a rinse tank 19.

On the main body panel 11, a detergent inlet 16 closed by a detergent lid 15 that swivels along a plane parallel to the inner surface of the door, an air intake 17 of a rinse tank 19, and a bayonet type. The rinse replenishment port, which is closed by the rinse lid 18 in which watertight packings (eg, rubber plate, etc.) are installed, the rinse amount adjustment knob 14 for setting the amount of one rinse, and the rinse remaining amount. A rinse level meter 12 for visually observing the amount from the outside and a discharge port 13 (the outlet part of the rinse discharge valve 40, which is usually a square hole) for discharging the rinse into the dishwasher cabinet are provided. ing. The air intake 17 is usually a small square hole in order to prevent the washing water in the storage from entering the rinse tank, and to improve drainage in the drained water after entering the rinse tank. It is desirable to use a large square hole in order to reduce the power consumption of the solenoid device 20 described later as much as possible and to reduce the size of the device itself. In that case, consider measures to prevent entry of washing and cleaning water. For example, the air intake port 17 may be covered with the bayonet type rinse lid 18. Since the detergent input port 16 can store only the amount of detergent for one treatment, it is necessary to measure an appropriate amount with a measuring spoon attached to the dishwasher and store it in the detergent input port 16 each time it is used. On the other hand, the rinse tank 19 can store a capacity for a suitable number of processing times to several times. To rinse, turn the rinse lid 18 from the position of the "closed" character near the rinse lid 18 of the main body panel 11 to the position of the "open" character, remove the rinse lid 18, and inject from the rinse replenishing port. When the color is visible up to the position of the "full" character near the rinse level meter 12 on the main body panel 11, the replenishment work is stopped while visually checking.

As shown in FIG. 3, the rinse level meter 12 is formed of a colored (for example, red, blue, or other) resin molding member on the level gauge plate support wall 58 below the rinse tank 19. A level gauge plate 55 is provided, and a plate prism 57 formed of a resin molding member of a substantially transparent color serving as a display window is provided on an upper portion (panel side of the main body panel 11) of the level gauge plate 55. , O-rings, V-packings, etc.) to improve watertightness and diagonally fixed to the main body panel 11. When the plate-like prism 57 comes into contact with the liquid surface of the rinse, the light guiding rate of that portion changes, so that the side touching the liquid surface appears as a color difference in the rinse level meter 12. Even when the door is open and there is no float, it is possible to know the remaining amount of rinse in any of the rinse tanks 19 similar to the float.

FIG. 2 is a rear view of the automatic detergent rinse thrower 10 rotated 180 degrees clockwise with respect to FIG. The rinse metering chamber 62 and the rinse metering adjusting shaft 61, which are the internal parts of the rinse tank 19 and which are originally invisible from the outside of the rinse tank 19, are shown by dotted lines. This is for indicating the mounting position of 61 and the like. A solenoid device 20 is provided on the back surface of the main body panel 11. The solenoid device 20 includes a solenoid in which a copper wire is wound around a cylindrical bobbin and connected to a solenoid terminal 21, a yoke 24 for forming a magnetic path around the outer periphery of the solenoid, and a current to the solenoid terminal 21. It is composed of an armature 22 which is sucked into the solenoid device 20 by flowing it, and is fixed to the main body panel 11 by inserting a screw into a screw hole provided in the yoke 24. The working end of the armature 22 is engaged with the valve lid latch shaft 30 which is constantly elastically biased by the latch compression coil spring 23 in the protruding direction. The valve lid latch shaft 30 is provided with a lid engaging claw 32 for holding the detergent lid 15 which is constantly elastically urged by a detergent lid torsion coil spring 54 in the opening direction in a closed position, and a rinse discharge valve 40. Although not shown in the drawing, it is formed with a valve locking claw 31 that locks to the valve protrusion formed on the operating end of the rinse shaft 41 of the valve body. Bombing has been activated. Although not shown, the rinse discharge valve 40 (substantially cylindrical, which resembles a syringe of a syringe, for example), the rinse shaft 41, an actuating compression coil spring, and a bellows (made of rubber). A circular valve seat hole (discussed below) provided in a discharge passage (considered to be rectangular) 67 inside the discharge port 13 of the main body panel 11 66), the bellows coupled to the tip of the rinse shaft 41, which is constantly elastically biased by the actuating compression coil spring in the direction of the valve seat, is pressed to block the discharge of the rinse. The detergent lid 15 is pivotally supported by a support shaft 50 penetrating the main body panel 11, and a lid projection 51 that engages with the lid engaging claw 32 of the valve lid latch shaft 30 is included in the support shaft 50. It is integrally connected to the end.

Here, although not directly related to the description of the rinse measuring and adjusting shaft 61 of the present invention, the operating procedure of the automatic detergent rinse inserter 10 for a dishwasher equipped with the rinse measuring and adjusting shaft 61 of the present invention will be described. Including, explain the operation procedure of the whole dishwasher. First, the rinse tank 19 has already been rinsed. Further, it is assumed that the detergent inlet 15 has the detergent lid 15 opened. At this time, the valve locking claw 31 of the valve lid latch shaft 30 and the valve projection of the rinse shaft 41 are engaged. Open the dishwasher door, measure an appropriate amount of the specified detergent with the measuring spoon attached to the dishwasher, store it in the detergent inlet 16, and then rotate the detergent lid 15 to close the basket. Put the tableware in the dishwasher / dryer cabinet and close the door. When the detergent lid 15 is closed, the lid projection 51 provided on the support shaft 50 of the detergent lid 15 engages with the lid locking claw 32 of the valve lid latch shaft 30. At this time, the valve lid latch shaft 30 which is constantly elastically urged by the compression coil spring of the valve lid latch shaft is a valve lid latch shaft pressing plate 52 provided on the support shaft 50, and is a panel of the main body panel 11. It is moved to the side, and the engagement between the valve locking claw 31 of the valve lid latch shaft 30 and the valve protrusion of the rinse shaft 41 is released.

When a power switch (for example, an auto-off type) is turned on and various processing switches are used to specify a cleaning time, a rinsing time, a drying time, etc. (which can be confirmed by a display lamp or the like), the processing is started. First, the electromagnetic water supply valve operates according to the processing procedure (program or software) stored in advance in the ROM or EEPROM of the microcomputer, and water (eg, water Water) is supplied. After water supply, according to the treatment procedure, the operation of the electromagnetic water supply valve is stopped, the heater for steam heating is operated, and when the hot water suitable for cleaning is turned off, the heater for heating steam is stopped, The circulating water pump for pumping the hot water (washing water) from the shower nozzles provided at the top and / or the bottom of the oven is operated to start hot water washing.

Then, when the solenoid device 20 is actuated by the processing procedure, the valve lid latch shaft 30 is rotated to release the engagement between the lid locking claw 32 and the lid projection 51, and the opening direction The detergent lid torsion coil spring 54 elastically urges the detergent lid 15 to open the detergent lid 15 to discharge the detergent into the storage. When the detergent lid 15 is opened, the valve lid latch shaft holding plate 52 moves the valve lid latch shaft 30 to the panel side of the main body panel 11, and the valve lid latch shaft holding plate 52 moves and The valve lid latch shaft is restored to the initial position by the elastic biasing action of the compression coil spring. Here, when the processing procedure stops the operation of the solenoid device 20, the valve locking claw 31 of the valve lid latch shaft 30 and the valve projection of the rinse shaft 41 are engaged.

When the designated cleaning time ends, the treatment procedure operates the electromagnetic drain valve to drain the used cleaning water, and after draining, the electromagnetic drain valve is deactivated and the electromagnetic drain valve is stopped. The water supply valve is activated (second time), and water is supplied to the inside of the storage from the water discharge port at the top of the storage. After water is supplied, the operation of the electromagnetic water supply valve is stopped according to the treatment procedure, the heater for steam heating is operated (second time), and the heater for heating steam is operated when hot water suitable for cleaning is reached. Stop and turn on the circulation pump to start the hot water rinse.

Then, when the processing procedure operates the solenoid device 20 (second time), the valve locking claw 31 of the valve lid latch shaft 30 pulls the valve protrusion of the rinse shaft 41, and rinses. The discharge valve 40 opens and the rinse is discharged into the chamber in a few seconds. However, when the air intake 17 is small, it may not be released properly after only one operation. Therefore, the processing procedure is determined to operate the solenoid device 20 once to several times within a predetermined time. There is.

When the designated rinsing time is over, the treatment procedure activates the electromagnetic drain valve (second time) to drain the rinse water after use, and after draining the electromagnetic drain valve. After stopping and operating the air blower, the heater for heating the steam is activated (third time) to start removing hot air from the water attached to the tableware. When the specified drying time ends, the treatment procedure operates the electromagnetic drain valve (third time) to drain the runoff water, and after draining, stop the electromagnetic drain valve operation and turn on the power switch. The processing is automatically terminated by turning it off (auto off). This completes the description of the operating procedure of the entire dishwasher / dryer.

FIG. 5 is a front view of the rinse tank portion 19 of the automatic detergent rinse dispenser 10 for a dishwasher equipped with the rinse metering adjustment shaft 61 of the present invention, and FIG. 6 is a conventional automatic detergent rinse dispenser. It is a front view of a rinse tank part. The reference numerals in FIG. 6 are the same as those in FIG. 5 for parts having the same names so that it is easy to compare FIG. 5 and FIG. As can be seen by comparing FIGS. 5 and 6, the rinse metering chamber 62 of the present invention is half the size of the conventional metering chamber, and as a result, the rinse storage amount can be increased more than the conventional one. . In the rinse tank 19, a syringe 65 related to the rinse discharge valve 40, a valve guide passage (considered to be a polygonal shape) 63, a valve seat 66, a discharge passage 67, a discharge port 13, and a rinse injection amount are measured. A rinsing measuring device 60 and a level gauge plate supporting wall 58 are provided. The rinse metering device 60 is a rinse having an arcuate partition wall 64 provided inwardly on the inner surface of the wall of the rinse tank 19 and a substantially semi-cylindrical body or a fan-shaped cylinder body projecting inside the partition wall 64. When the door is in the open state, the rinse in the rinse tank 19 enters from a rinse inlet 68 (considered to be a prism) and fills the rinse measuring chamber 62. When the door is in the closed state, the excess rinse is left in the rinse tank through the rinse outlet 69 (considered to have a rectangular shape), leaving the rinse to be measured. The diameter of the rinse metering adjustment shaft 61 is set so that a predetermined gap is formed between the rinse metering adjustment shaft 61 and the inner surface of the arcuate partition wall 64, and the rinse metering adjustment shaft 61 is directly connected to the rinse amount adjusting knob 14 and is rotatable in the left-right direction. (A watertight packing 56 or the like is attached to the main body panel 11 so that the watertightness is improved.) The shape of the portion that determines the measurement volume is a substantially semi-cylindrical body or fan-shaped body. In the present invention, the rinse amount adjusting knob 14 is changed in three stages of angles, and the rinse supply amount is changed according to each angle.

FIG. 4 is a partial perspective view of the rinse metering chamber 62 and the rinse metering adjustment shaft 61 in FIG. 2 for explaining the operation of the rinse metering adjustment shaft 61 of the present invention. FIG. 4A shows the rinse amount adjusting knob 14 set to "1" (not shown). The partition wall 64 and the rinse measuring and adjusting shaft 61 are substantially semi-cylindrical or fan-shaped. The volume of the space surrounded by the body is minimized, and the amount of rinse supplied at this time is also minimized. FIG. 4B shows the rinse amount adjusting knob 14 set to “2” (not shown), the volume is larger than the above amount, and the rinse amount is larger than the above amount. FIG. 4 (c) shows the case where the rinse amount adjusting knob 14 is set to "3" (not shown), the volume becomes maximum, and the rinse input amount at this time becomes maximum. Based on such a principle, the shape of the rinse metering adjustment shaft 61 that determines the metering volume does not require a design involving complicated calculation, and can be simplified by changing the shape of the substantially semi-cylindrical body or fan-shaped body. You can change the adjustment range.
