Description

DETAILED DESCRIPTION OF THE INVENTION In dishwashers, performance is improved by using liquid detergents for cleaning and drying finishes for better drying. Therefore, there is a need for a device for dispensing liquids such as liquid detergents and dry finishing agents for dispensing them into the dishwasher at any effective time.

However, conventional liquid injection devices have not been fully satisfactory. The conventional configuration will be explained based on FIG. 1. In the figure, 1 is the main body of the dishwasher, 2 is a tank installed inside the main body 1 of the dishwasher, and 3 is a washing pump that circulates the washing water in the tank 2. So, the cleaning water is sent to nozzle 4.
is injected by. 6 is a discharge pump for discharging the wash water after use. 6 is a k-th dish basket for efficiently washing dishes, 7 is a lid that can be opened and closed in front of the dishwasher main body 1, and inside it is a device for introducing liquids such as electrical parts, liquid detergent, drying finishing agent, etc. 8 is built-in.

The conventional liquid injection device 8 will be explained in detail with reference to FIGS. 2 and 3. Reference numeral 9 denotes a vessel-shaped measuring chamber, which is rotated by an adjustment knob 1o. A QIJ ring 11 is attached to a shaft portion provided integrally with the measuring chamber 9. and lid 7
When opened and leveled, the liquid in the liquid reservoir 8& is in the measuring chamber 9.
When the lid 7 is closed, excess liquid returns to the liquid reservoir EIL from the open end of the measuring chamber 9 and the set amount is measured. Then, when the valve 8b is opened at an arbitrary time, the liquid is discharged into the tank 2 through the hole 9bl of the metering chamber 9 and the pulp 8bi. By rotating the measuring chamber 9, the number of stitches to be measured when the lid 7 is closed changes, and a desired setting t can be obtained.

By the way, in this case, since the rotation angle of the measuring chamber 9 is narrow, within 9 cf', it is difficult to make fine adjustments using the adjustment knob 10.

The present invention is designed to make it possible to increase the rotation angle of the adjustment knob in order to eliminate the sluggishness of the conventional example, that is, to make it easier to adjust the amount of liquid to be set.

An embodiment of the present invention will be explained with reference to FIGS. 4 and 6.

The same parts as in FIGS. 1 to 3 are designated by the same reference numerals. The key point of the configuration is that gears 9el and 121L are provided on the outer bottom surface of the measuring chamber 9 and the knob shaft 12.

The knob shaft 12 and the adjustment knob 1o are integrated with screws or adhesive, and rotate at the same time. Gear 9e also in measuring chamber 9
When the gear 9e is turned off, the gear 9e engages with the gear 121L of the knob shaft 12, and the rotation of the adjustment knob 1o is transmitted to the metering chamber 9. Therefore, by rotating the adjustment knob 10, the metering chamber 9 can be set at any angle, and a desired set amount of liquid can be obtained.

Here, the gear ratio is set so that the rotation angle of the adjustment knob 12 is as large as possible with respect to the rotation angle of the measuring chamber 9. This allows the rotation angle of the adjustment knob 1o to be large, making adjustment easier. ing. The liquid metered in the metering chamber 9 is introduced into the tank 2 by opening the pulp 8bi at any effective time. An O-ring 13 is attached to the measuring chamber 9 and the knob shaft 12 to prevent liquid from flowing out.

Examples of these assembly configurations are shown. Gear of measuring chamber 9 9o
A collar 9C is provided at the end of the portion. First, the measuring chamber 9 is assembled inside the main body of the liquid injection device 8, and then the knob shaft 1
Incorporate 2. At that time, the aforementioned collar 9C is the knob shaft 12.
One person is caught between the gear 12& and the liquid injection device 8. The knob shaft 12 is engaged with the adjustment knob 10 from the outside of the liquid injection device 8, and integrated by screwing or gluing. That is, the measuring chamber 9 and the main body of the liquid injection device 8 are sandwiched between the knob shaft 12 and the adjusting knob 10, and the movement of the measuring chamber 9 in the direction shown in FIG. 6 is prevented from rain. This is to prevent the surface 9d of the metering chamber 9 from coming into contact with the liquid injection device 8, causing increased friction and preventing smooth rotation.

In addition, a protrusion 101L is provided on the adjustment knob 1o,
If a groove is provided in the liquid injection device 8 to restrict rotation, the rotation range is determined and rotation is safe.

As is clear from the above embodiments, in the present invention, the rotation angle of the adjustment knob can be made larger than the rotation angle of the metering chamber, so that the set amount of liquid can be easily finely adjusted.

Also, if you adjust the assembly configuration of the adjustment knob and knob shaft,
Once the device is assembled, the parts will no longer come apart, making later assembly advantageous. Furthermore, liquid leakage can be inspected at this point, leading to early detection of defective parts. Therefore, there is less loss of parts, which is advantageous in terms of price.
