本発明は水１ｔＨＪ算機構による定水量給水弁および注
水が実質的に成されているか否かを報知する報知手段を
備えた洗濯機の給水装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water supply device for a washing machine, which is equipped with a constant water supply valve using a water 1 tHJ calculation mechanism and a notification means for notifying whether or not water is being poured substantially.
従来、洗濯機の給水′方法としては、本道蛇口を手動で
開閉して洗濯槽への給水を行うか、電磁給水弁と水位検
知用圧力スイッチを用いて自動給水を行う方法がある。Conventionally, water has been supplied to a washing machine by manually opening and closing a main faucet to supply water to the washing tub, or by using an electromagnetic water supply valve and a water level detection pressure switch to automatically supply water.
前者は手動で筒車であるが使用勝手が悪く、水道蛇口を
閉め忘れると水が溢れるといった不都合があシ、後者は
電磁給水弁と圧力スイッチが必要で一気回路が複°雑、
且つコスト高になるという欠点があった。The former is a manual hour wheel, but it is not easy to use, and there are inconveniences such as water overflowing if you forget to close the water faucet.The latter requires an electromagnetic water supply valve and a pressure switch, and the circuit is complicated.
In addition, there was a drawback that the cost was high.
本発明は、上記従来の問題を解決するもので、注水量を

より使用者に知らせるものである。The present invention solves the above-mentioned conventional problems.The basic structure of the present invention is to integrate the amount of water injected using an impeller rotating with the water flow, and automatically stop the water injection when a certain amount of water is injected. When water is not substantially being poured, that is, when a very small amount of water is being poured or when no water is being poured at all, the user is notified by operating the notification means.
以下、本発明の実施例を添付図面に基づいて説明する。Embodiments of the present invention will be described below with reference to the accompanying drawings.

、２９は防水用のベローズである。A branch pipe 15 is installed horizontally in the water injection tube 1 so as to be located upstream of the valve seat 2 in the figure.
The operating rod 16, whose tip abuts against and separates from it, is slidably inserted through the O-ring backing 17! A coil spring 18 is inserted between the branch pipe 16 and the operating rod 16, which urges the operating rod 16 in a direction away from the spherical valve body 3, that is, in a direction to push the operating rod 16 out of the water injection barrel 1. 19
is a spring plate whose one end is fixed to the base plate 20, and the protrusion 19' on the other end abuts against the cam 13. Further, the rear end 16' of the operating rod 16 is in contact with the intermediate portion of the spring plate 19. 2
1 is a water supply hose, and 22 is a holding band thereof. - A cam is provided which frictionally engages with the final gear 12 of the reduction gear group. The scale 24 from 0 to 4o11 corresponds to the water supply heir 23. Note that this scale 24 is from O to 1o.
OI! , which is determined by the reduction ratio of the reduction gear. When the arrow point 23a of the water supply heir 23 is at the 0 point on the scale 24, the protrusion 19' of the spring plate 19
The spring plate 19 is moved to the right in the figure by the biasing force of the coil spring 18 via the operating rod 16, and the spherical valve body 3 moves to the position where the valve seat 2 is closed. At this time, rotate the water supply heir 23 in the direction of the arrow a to set the arrow point 23a at 3 on the scale.
02, the protrusion 19' is located on the circumference of the cam 13, and the operating rod 16 and the spherical valve body 3 are connected to the coil spring 18.
is pushed to the left in the figure against the urging force of , the valve seat 2 is opened, and water is injected by the water supply hose 21. The impeller 4 is rotated by this water, which is decelerated by the small gear 6' and the reduction gear group 6 to 11, and the cam 13 rotates together with the water supply head 23 in the direction indicated by the arrow in the figure. , - the protrusion 19' engages with the notch 14, and the coil spring 18
Due to the biasing force, the suppression of the spherical valve body 3 by the operating rod 16 is released, the spherical valve body 3 closes the valve seat 2, and water injection is stopped. On the other hand, a pressure receiving lever 26, which is a water flow pressure receiving part that operates by receiving water injection pressure at its tip, is arranged corresponding to the water injection outlet 1' of the water injection tube 1, and the other end of this pressure receiving lever 26 is connected to the base plate 26. Also, this pressure receiving lever 26
A water flow detection switch 27, such as a micro switch, is provided by contacting the protrusion 27' with the water flow detection switch 27. 028 is a partition wall that prevents splashes of water from hitting the water flow detection switch 27, and 29 is a waterproof bellows. .

ある表示ランプを点灯させる。Reference numeral 30 denotes a notification means connected to the power supply circuit in series with the water flow detection switch 27, and is composed of an indicator rung.When the pressure receiving lever 26 is displaced in response to the water pressure from the water flow outlet 1', the protrusion 27 The pressure receiving lever 26 is released from ', the water flow detection switch 27 is turned on, and the indicator lamp serving as the notification means 30 is turned on.

ランプが点灯しないように考慮されている。There is substantially no water pressure from the water outlet 1', e.g.
When the water is flowing in a very small amount per minute or not at all, the pressure receiving lever 25 does not bend and the water flow detection switch 27 does not bend.
does not turn on, and the above indicator lamp does not light up. That is, extremely small water flow, for example 11! , at 7 minutes, the impeller □wheel 4 may not rotate due to rotational friction resistance or water flow loss (water does not hit the blades enough), so in such cases, consideration should be given so that the indicator lamp does not light up. has been done.

戻り、給水は自動的に止まる。Also, if the amount of water injected is extremely low and is not practically secured, for example, 12! In the case of a water injection amount of about one minute, the impeller 4 may not rotate as described above, so the display rung does not light up as described above. As a result, the users see the lighting of the indicator lamp and inject water, thereby preventing the occurrence of a problem in which the amount of water injected is too small and automatic water supply cannot be performed. When the water injection described above is performed at 30° C., the water supply heir 23 and the cam 13 return to the 0 position on the scale 24, and the water supply automatically stops.

。In addition, although the example explained the case where an indicator lamp was used as the notification means, a buzzer may be used instead. In this case, when the water flow pressure receiving part stops sensing the water flow pressure, , the water flow detection switch may be turned on and the buzzer may be energized to make it sound.

行える等、その工業的価値はきわめて大きい。As described above, the water supply device for a washing machine according to the present invention has a simpler configuration and is less expensive than a conventional water supply device using an electromagnetic water supply valve and a pressure switch, and the water supply status can be easily and easily detected by the notification means. It can be reliably determined and prevents troubles such as being unable to integrate the amount of water due to the extremely small amount of water.
Its industrial value is extremely great, as it allows the user to perform laundry tasks smoothly with proper operation.
